Description

Shower nozzle protection device of 3D printer Technical Field The utility model relates to the technical field of 3D printers, in particular to a spray head protection device of a 3D printer. Background The 3D printer realizes object construction by stacking materials layer by layer, and a spray head of the 3D printer is used as a core execution component and needs to be frequently moved in the printing process. However, existing 3D printer heads are generally lacking in effective protective measures, and when a program misjudgment, a mechanical failure, or external disturbance occurs in the operation of the apparatus, the heads may collide with the printer housing, the table, or other components. The collision is light, so that the position of the spray head is offset, the printing precision is reduced, and the internal structure of the spray head is damaged, materials are leaked and even the whole machine is in fault, so that the maintenance cost is increased, and the production progress is possibly influenced. The existing protection scheme depends on limit alarm of the equipment software layer, but has lag response and can not directly buffer physical impact. Therefore, a nozzle protector of a 3D printer is now proposed. Disclosure of utility model In order to overcome the above-mentioned drawbacks of the prior art, the present utility model provides a nozzle protection device of a 3D printer, so as to solve the above-mentioned problems in the prior art. In order to achieve the above purpose, the utility model provides the technical scheme that the spray head protection device of the 3D printer comprises a lantern ring, wherein a plurality of locking assemblies are arranged on the lantern ring, protection assemblies are arranged between every two adjacent locking assemblies, each protection assembly is connected with a locking sleeve, and each protection assembly is connected with the lantern ring through a corresponding locking sleeve. Preferably, the locking assembly comprises a screw, a knob, an axle seat, clamping plates and guide rods, wherein the knob is arranged at one end of the screw, the axle seat is arranged at the other end of the screw, the axle seat is connected with the clamping plates, and two guide rods positioned at two sides of the screw are arranged at one side of the clamping plates. Preferably, the lantern ring is provided with a screw hole, and two sides of the screw hole are provided with guide holes. Preferably, the screw rod is screwed with the screw hole, and the guide rod is inserted into the corresponding guide hole. Preferably, the protection component comprises a support rod, a guard plate, a baffle disc, a protruding head and a spring, wherein the guard plate is arranged at one end of the support rod, the baffle disc is arranged at the other end of the support rod, the protruding head is coaxially arranged at one side of the baffle disc, and the spring is sleeved on the protruding head. Preferably, the lantern ring is provided with a mounting groove, a bump is arranged in the mounting groove, the locking sleeve is screwed on the notch of the mounting groove, and the supporting rod is connected with the baffle disc in the mounting groove through the locking sleeve. Preferably, the first pole piece is installed in the middle of the protruding head, and the second pole piece is installed in the middle of the protruding block. The utility model has the technical effects and advantages that: The annular protection components are formed through the plurality of protection components on the lantern ring, if collision occurs in the moving process of the spray head, the guard plate can firstly contact with a collision object, impact force is absorbed through spring compression, the spray head is prevented from being directly damaged, the locking component can adjust the position of the clamping plate through the matching of the screw rod and the guide rod, the lantern ring is stably installed at the top of the spray head, and the installation reliability of the protection device is improved.
