[0003] At present, during the spraying of silicone earphone sleeves, the spraying head is controlled by a guide rail to repeatedly move on the silicone earphone sleeves placed on the conveyor belt for spraying, so that the spraying effect is better. The silicone earphone sleeves will be placed on a bottom plate. However, with the movement of the conveyor belt and the continuous repeated movement of the spraying head, the bottom plate will shake or the spraying head will touch the silicone earphone sleeves, resulting in the silicone earphone sleeves falling down. At this time, a part of the silicone earphone sleeves will not be fully sprayed by the spraying head, resulting in defective products and affecting the overall processing efficiency. Content of the Utility Model

[0004] In order to solve the above problems; the purpose of the utility model is to provide a spraying device for producing silicone earphone sleeves.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: a spraying device for producing silicone earphone sleeves, including a conveyor belt and a mounting frame.

Detailed Embodiment

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0017] Embodiment: As Figures 1-4As shown, the utility model provides a spraying device for the production of silicone earphone covers, including a conveyor belt 1 and a mounting frame 11, the spray head 15 conveyor belt 1 is arranged directly above the top of the mounting frame 11, and the spray head 15 mounting frame 11 is internally provided with a spraying structure directly above the conveyor belt 1, and a base plate 2 is placed on the upper surface of the spray head 15 conveyor belt 1, and a mounting plate 21 is provided directly above the base plate 2 of the spray head 15. A plurality of through grooves 22 distributed at equal intervals are opened through the mounting plate 21 of the spray head 15, and two symmetrically combined support blocks 23 are slidingly provided in the through grooves 22 of the spray head 15, and the bottoms of the two support blocks 23 of the spray head 15 are both inclined, and a top block 24 corresponding to the bottoms of the two adjacent support blocks 23 is fixed on the upper surface of the base plate 2 of the spray head 15.

[0018] A vertically arranged screw rod 25 is threadedly inserted at the middle position of both ends of the mounting plate 21 of the spray head 15. The rotation of the arranged screw rod 25 can drive the threaded mounting plate 21 to move up and down along itself, thereby making the top block 24 contact and separate from the support block 23; a bearing 27 is fixedly arranged on the upper surface of the bottom plate 2 of the spray head 15 below the screw rod 25, and the bottom of the screw rod 25 of the spray head 15 is fixedly connected to the bottom of the bearing 27 to fix the bearing 27 to the bottom plate 2. At this time, the bottom of the screw rod 25 is fixedly arranged at the inner ring of the bearing 27, so that when the screw rod 25 rotates, the bottom is stably connected to the bottom plate 2 to ensure the stability of the screw rod 25 during rotation; a rotating wheel 26 with an anti-slip strip on the surface is fixed on the top of the screw rod 25 of the spray head 15. The rotating wheel 26 can facilitate the staff to directly drive the screw rod 25 to rotate quickly, thereby improving the convenience of operation.

[0019] The inner wall of the through slot 22 of the spray head 15 is provided with a groove 3 near the expansion block 23, and a moving block 31 is slidably provided in the groove 3 of the spray head 15. One side of the moving block 31 of the spray head 15 is fixedly connected to the expansion block 23, and a spring 32 is fixedly provided between the side of the moving block 31 of the spray head 15 away from the expansion block 23 and the inner wall of the groove 3. When the expansion block 23 is pushed by the top block 24 below, it will squeeze the spring 32 along with the moving block 31. At this time, the two expansion blocks 23 will gradually separate into blocks to effectively position the silicone earphone cover on themselves. At the same time, as the top block 24 subsequently separates from the two expansion blocks 23, the spring 32 will push the moving block 31, so that the two expansion blocks 23 move to the initial merged state until the next use.

[0020] Vertically arranged uprights 28 are movably inserted at the four corners of the spray head 15 mounting plate 21, and the bottoms of the spray head 15 uprights 28 are fixedly arranged on the base plate 2. The arranged uprights 28 can ensure the stable movement of the mounting plate 21 when the mounting plate 21 is driven downward by the screw rod 25, and prevent deviation from causing normal contact between the top block 24 and the support block 23.

[0021] The spraying structure of the spraying head 15 includes an electric guide rail 12. The electric guide rail 12 of the spraying head 15 is fixedly installed on the top of the mounting frame 11 and is located directly above the conveyor belt 1. A slider 13 for cooperative use is installed on the electric guide rail 12 of the spraying head 15. A cross plate 14 is fixedly installed on the lower surface of the slider 13 of the spraying head 15. Spraying heads 15 are fixedly arranged on the lower surface of the cross plate 14 of the spraying head 15 at equal intervals. When the conveyor belt 1 drives the silicone earphone covers inserted onto the expanding blocks 23 on the mounting plate 21 to move, the electric guide rail 12 will drive the slider 13 to drive the spraying heads 15 on the lower surface of the cross plate 14 to move horizontally and vertically repeatedly, spraying the silicone earphone covers gradually passing below the mounting plate 21. In this way, the surfaces of the passing silicone earphone covers can be sprayed, and the spraying is more comprehensive. It should be noted that the spraying heads 15 are specifically connected to the storage of the paint through a delivery pipe, and the storage tank can be arranged on the mounting frame 11.

[0022] Working principle: During use, the staff can directly insert the silicone earphone covers to be sprayed onto the two expanding blocks 23. After the expanding blocks 23 on one mounting plate 21 are filled with silicone earphone covers, the lead screw 25 can be directly driven to rotate at this time. The mounting plate 21 with a thread provided on the lead screw 25 will be driven to move downward along the lead screw 25. During the downward movement of the mounting plate 21, the top block 24 fixedly arranged on the upper surface of the bottom plate 2 will be inserted between the two expanding blocks 23 at this time. The two expanding blocks 23 will gradually separate to effectively position the silicone earphone covers sleeved on themselves, and at the same time, the side walls of the silicone earphone covers will be expanded to make them better receive the spraying of the top spraying heads 15, improving the processing efficiency. Subsequently, the bottom plate 2 moves to the lower part of the cross plate 14 along with the conveyor belt 1. At this time, the electric guide rail 12 will drive the slider 13 to drive the spraying heads 15 on the lower surface of the cross plate 14 to move horizontally and vertically repeatedly, spraying the silicone earphone covers gradually passing below the mounting plate 21. In this way, the surfaces of the passing silicone earphone covers can be sprayed, and the spraying is more comprehensive.

[0023] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these changes and modifications.
