Abstract

FIELD: feeding devices. SUBSTANCE: invention describes a device for feeding buckets with a separating function, which includes the following elements: a bucket feeding mechanism, which includes a guide bracket, and a bucket separating mechanism, which includes a roller unit and a power unit. The guide bracket serves to set the direction of movement of the buckets. The roller unit is kinematically connected to the power unit, and a helical groove with a gradually increasing pitch is made on the surface of the roller unit. A side element is made on the outer surface of the bucket body, contacting the helical groove. When the roller unit rotates, the bucket is driven and guided by the bracket. Since the pitch of the helical groove gradually increases, the distance between adjacent buckets also gradually increases as the buckets are moved by the roller unit. The suction force between stacked buckets is distributed over several stages, reducing the load during separation. EFFECT: reducing the load on the separation mechanism and increasing the stability of the bucket position during feeding. 7 cl, 6 dwg

Description

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] This application claims priority to Chinese Patent Application No. 202422662277.2, filed on November 1, 2024, entitled "Bucket Feeding Apparatus with a Separating Function," the entire contents of which are incorporated herein by reference. AREA OF TECHNOLOGY [0002] The present application relates to the technical field of material feeding mechanisms, in particular to a device for feeding buckets with a separating function. LEVEL OF TECHNOLOGY [0003] Pad printing applications include processing buckets as printed items. For ease of storage before and after printing, the buckets are stacked. While compact, this method of storage results in the formation of sparse spaces between the buckets. [0004] The large depth of the buckets results in the formation of a cavity with an increased vacuum level between the two stacked buckets. Therefore, a significant force is required to separate the buckets. After separation, the bucket is typically placed into the printing plate. In currently available separation mechanisms, the rear bucket is fixed, and the front bucket is pushed by a rod; after separation, the rod moves the front bucket into the printing plate. Since this separation method requires overcoming a significant suction force caused by the vacuum between the buckets, the rod must have a high power. The combined effect of the significant suction force and the rod force not only leads to damage to the front bucket, but also imparts high kinetic energy to it at the moment of release. As a result, the position of the bucket during feeding becomes unstable (i.e., it is easily displaced) due to the effect of the vacuum. This, in turn, affects the accuracy of its installation relative to the printing form, leading to low feed efficiency and high load on the equipment.
