Description

Technical Field

[0001] This utility model relates to the field of facial mask production equipment, and in particular to an automatic feeding device for a dryer. Background Technology

[0002] In the production of face masks, grippers are usually used for feeding to facilitate individual sheet inspection, drying and subsequent processing. This improves production automation, increases production efficiency and reduces manual operation. Through the close cooperation between the grippers and the equipment system, they play an important role in both the precise control of the feeding process and the handling of dried materials.

[0003] However, facial masks are delicate and easily damaged consumer products, with relatively fragile materials, especially the mask sheet after it becomes wet. These materials are easily damaged by external forces, leading to breakage, deformation, or loss of function. Therefore, excessive clamping force or uneven contact between the grippers during handling can damage the mask, affecting the quality of the final product and production efficiency. To address these issues, an automatic feeding device for a dryer is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic feeding device for a dryer, which aims to improve the problem that the grippers in the prior art are prone to damaging the face mask.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the connecting rod is pushed by the second telescopic cylinder, so that the fixing plate with the suction nozzle comes into contact with the mask.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of an automatic feeding device for a dryer, comprising a base 1, a support column 2 fixedly connected to the top of the base 1, a conveyor 5 fixedly connected to the top of the base 1, a top plate 3 fixedly connected to the top of the support column 2, a driving assembly mounted in the middle of the top plate 3, and a second telescopic cylinder 22 fixedly connected to the bottom of the driving assembly. The driving assembly includes an electric slide rail 4 fixedly connected to the middle of the top plate 3, an electric slider 21 slidably connected to the middle of the electric slide rail 4, and the second telescopic cylinder 22 fixedly connected to the bottom of the electric slider 21. A groove is formed in the middle of the top plate 3, and the electric slider 21 and the second telescopic cylinder 22 are slidably connected in the middle of the groove. First, the electric slide rail 4 is driven, so that the two electric sliders 21 can drive the two second telescopic cylinders 22 to move synchronously in the groove, thereby ensuring that the distance between the two second telescopic cylinders 22 remains constant.

[0033] Reference Figures 2-4 The output end of the second telescopic cylinder 22 is fixedly connected to a connecting rod 11, the other end of the connecting rod 11 is fixedly connected to a fixing plate 16, the outer side of the fixing plate 16 is fixedly connected to a connecting block 8, the middle of the connecting block 8 is fixedly connected to a suction nozzle 18, the top of the fixing plate 16 is fixedly connected to a frame 12, the top of the frame 12 is fixedly connected to an air pump 14, the output end of the air pump 14 is equipped with a connecting assembly, the connecting assembly includes a diverter pipe 20, the diverter pipe 20 is fixedly connected to the output end of the air pump 14, the connection port of the diverter pipe 20 is fixedly connected to a connecting pipe 17, the other end of the connecting pipe 17 is fixedly connected to an air supply pipe 9, the outer circumference of the air supply pipe 9 is rotatably connected to a threaded interface 15, the threaded interface 15 is threadedly connected to the outer circumference of the suction nozzle 18. When the second telescopic cylinder 22 moves to the mask, it drives the connecting rod 11, which in turn pushes the fixing plate 16 to move. This allows the fixing plate 16 to drive the suction nozzle 18 to contact the mask via the connecting block 8. Then, the air pump 14 at the top of the frame 12 is driven to pump air. Under the action of the diversion pipe 20, multiple connecting pipes 17 can be connected, allowing the connecting pipes 17 and the air supply pipe 9 to connect multiple suction nozzles 18 in series. This allows multiple suction nozzles 18 to simultaneously use vacuuming to adsorb the mask, so that the second telescopic cylinder 22 can lift the mask and move it to the top of the conveyor 5 via the electric slide rail 4 and the electric slider 21. The mask is then placed on the conveyor 5, preventing damage to the mask during the feeding process and ensuring the quality and production efficiency of the mask during feeding. Since the two second telescopic cylinders 22 are synchronized, the mask can be repeatedly lifted from both sides for rapid feeding.

[0034] Reference Figures 2-4A first telescopic cylinder 13 is fixedly connected to the middle of the fixed plate 16. A pressure plate 10 is fixedly connected to the output end of the first telescopic cylinder 13. A telescopic rod 19 is fixedly connected to the bottom of the fixed plate 16. The other end of the telescopic rod 19 is fixedly connected to the top of the pressure plate 10. Multiple through holes are opened in the middle of the pressure plate 10. The suction nozzle 18 is slidably connected to the middle of the multiple through holes. The first telescopic cylinder 13 is located below the frame 12. Before the suction nozzle 18 adsorbs the mask, the first telescopic cylinder 13 is driven to move the pressure plate 10 downward, so that the pressure plate 10 can flatten the mask and prevent wrinkles from forming when the mask is adsorbed. Similarly, when the mask is placed on the conveyor 5, the pressure plate 10 presses down, and when the air pump 14 depresses, it can prevent the mask from forming wrinkles on the conveyor 5, ensuring the quality of mask production. At the same time, the stability of the pressure plate 10 during movement is ensured by the support of the telescopic rod 19.

[0035] Reference Figure 1 A positioning rod 7 is fixedly connected to the top of the base 1, and a pad 6 is installed on the top of the base 1. The positioning rod 7 can position the mask so that the suction nozzle 18 can accurately adsorb the mask. The removable and cleanable pad 6 can prevent the bottom of the mask from contacting the base 1, ensuring that the bottom of the mask is not contaminated.

[0036] Working principle: The second telescopic cylinder 22 pushes the connecting rod 11, causing the fixing plate 16 at the bottom of the connecting rod 11 to bring the suction nozzle 18 into contact with the mask. Then, the air pump 14 is driven to draw air, thereby adsorbing the mask onto the suction nozzle 18. This allows the second telescopic cylinder 22 to lift the mask. The electric slide rail 4 then allows the electric slider 21 to move the second telescopic cylinder 22 to the top of the conveyor 5. At the same time, the second telescopic cylinder 22 places the mask on the conveyor 5. When the air pump 14 releases the air pressure, the mask will fall back onto the conveyor 5, thus ensuring the quality and production efficiency of the mask during the feeding process.

[0037] The first telescopic cylinder 13 drives the pressure plate 10 to move downwards so that the pressure plate 10 can flatten the mask before the suction nozzle 18 adsorbs it, thereby preventing the mask from wrinkling. At the same time, after the mask is placed on the conveyor 5, the pressure plate 10 can flatten the mask again on the top of the conveyor 5 for inspection.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
