Abstract

The invention discloses an embroidering method of an embroidering machine, which comprises the following steps of controlling a movable blade to swing back to a first retreating position before an embroidering needle is first needled, controlling the embroidering needle to carry an upper thread below a needle plate after the embroidering needle is first needled, controlling the movable blade to swing back for the second time until the embroidering needle is completely opened after the embroidering needle is first needled to pass through the needle plate, controlling the movable blade to swing towards a fixed blade for the first time before the embroidering needle is needled to pass through the needle plate, stopping the preliminary staggered position when the movable blade and the fixed blade are not completely closed, and controlling the movable blade to swing from the preliminary staggered position to the fixed blade slowly when the embroidering needle is second needled to be needled after the embroidering needle is second needled. The embroidering method of the embroidery machine can not only slightly loosen the bottom thread when the embroidery machine embroiders, but also cut the thread ends of the upper thread, prevent the residue of the overlong upper thread ends on the embroidery product and improve the quality of the embroidery product.

  5. 5. The embroidery method according to claim 1, wherein in the step S02, the embroidery needle is controlled to pass through the needle plate for the first time and bring the upper thread to the lower side of the needle plate, and then the embroidery needle is controlled to swing back for the second time until the embroidery needle is completely lifted up to the right place after the embroidery needle is lifted up for the first time.
  6. 6. The embroidering method according to claim 1, wherein in the step S03, the initial swing angle of the movable blade to the fixed blade is 40 °.
  7. 7. The embroidering method according to claim 1, wherein in the step S04, the movable blade swings from the preliminary intersecting position toward the fixed blade until the movable blade and the fixed blade are completely closed, and the swing angle of the movable blade is 20 °.
  8. 8. The embroidering method according to claim 1, wherein in the step S04, a maximum angular velocity ω of the movable blade is equal to or less than 0.2rad/S during the swing of the movable blade from the preliminary intersecting position to the fixed blade.
  9. 9. The embroidering method according to claim 8, wherein in the step S04, a maximum angular velocity ω of the movable blade is 0.17rad/S during the swing of the movable blade from the preliminary crossing position to the fixed blade.
  10. 10. The embroidery method according to claim 1, wherein in the step S04, the movable blade and the fixed blade are completely closed when the embroidery needle is lifted to the fully lifted position for the second time, so as to cut thread ends, and the embroidery needle is controlled to continue to be lowered after the embroidery needle is lifted to the fully lifted position for the second time.

Description

Embroidery method of embroidery machine Technical Field The invention belongs to the technical field of embroidery machines, and relates to an embroidery method of an embroidery machine. Background Embroidery machines are used to embroider patterns on embroideries (embroidering cloth, leather, etc.). The thread cutting mechanism of the embroidery machine is used for cutting the upper thread and the bottom thread after embroidery. Referring to fig. 2 to 5, the thread cutting mechanism of the embroidery machine comprises a mounting seat 1, a movable blade 2 capable of swinging, a fixed blade 3 and a thread locking elastic sheet 5, wherein a rotatable rotating shaft 4 is mounted on the mounting seat 1, the movable blade 2 is mounted at the upper end of the rotating shaft 4, the output end of an external driving mechanism is connected with the rotating shaft 4, the movable blade 2 is driven to swing through the rotating shaft 4 during operation by the external driving mechanism, the fixed blade 2 is fixed on the mounting seat 1 and is positioned at the upper side of the movable blade 2, and the thread locking elastic sheet 5 is fixed on the mounting seat 1 and is positioned at the lower side of the movable blade 2. When embroidery is performed by the embroidery machine, the movable blade 2 and the fixed blade 3 are in a staggered state, as shown in fig. 5, when thread cutting is needed after the embroidery is completed, the movable blade 2 is driven by an external driving mechanism to swing backwards to be opened, the movable blade 2 and the fixed blade 3 are mutually separated after the movable blade 2 is opened in place, then the movable blade 2 is driven by the external driving mechanism to swing forwards, when the movable blade 2 and the fixed blade 3 swing forwards in place, cross-section threads and bottom threads are staggered, at the moment, as shown in fig. 5, the lock thread elastic sheet 5 and the movable blade 2 are matched to clamp and lock the bottom threads, positioning of the bottom threads is realized, position of the bottom threads is prevented, and the upper threads and the bottom threads form a ring to pull the bottom threads when the next embroidery is performed, so that the re-embroidery is realized. However, the bottom thread is easily clamped by the thread locking elastic sheet 5 and the movable blade 2, the clamping force of the bottom thread is too large, the upper thread can not pull the bottom thread upwards, the embroidery can not be normally performed, the abnormal condition of virtual embroidery is caused, and the quality of embroidery is reduced. The applicant discloses a embroidery control method of an embroidery machine in the prior invention patent application CN202411504604X, and solves the technical problem that the bottom thread is clamped by a thread locking elastic sheet and a movable blade too tightly to be pulled up by an upper thread by the embroidery control method. However, in the actual production process, although the technical problems are solved, the thread ends of the upper thread are overlong during embroidery, and the overlong thread ends of the upper thread remain on the embroidery, so that the quality of the embroidery is affected. Disclosure of Invention The invention aims to provide an embroidering method of an embroidering machine, which aims to solve the technical problem that thread ends of upper threads are overlong during embroidering. In order to solve the technical problems, the technical scheme adopted by the invention is that the embroidering method of the embroidery machine comprises the following steps: step S01, before the embroidery needle is first put down, controlling the movable blade to swing back to a first back position for the first time, wherein the back angle of the first swing is alpha; step S02, controlling the embroidery needle to be placed down for the first time to bring the upper thread below the needle plate, and controlling the movable blade to swing back for the second time until the embroidery needle is completely opened after the embroidery needle is lifted up for the first time to pass through the needle plate; step S03, controlling the embroidery needle to be needled for the second time, controlling the movable blade to initially swing towards the fixed blade before the embroidery needle passes through the needle plate, and stopping the preliminary staggered position when the movable blade and the fixed blade are not completely closed; Step S04, after the embroidery needle is put down for the second time, when the embroidery needle is started for the second time, the movable blade swings from the primary intersection position to the fixed blade until the movable blade and the fixed blade are completely closed so as to cut off the thread end. Further, in the step S01, before the embroidery needle is first put down, the embroidery needle is located above the embroidery material, and the movable blade and the fixed blade are
