Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper pulp molding, in particular to an automatic spraying device for paper pulp molding. Background Art
[0002] Materials produced by pulp molding, such as paper bowls, paper cups and paper plates, need to be sprayed with a spray agent on the surface after the mold is formed. The spray agent forms a dense protective film on the surface of the material, thereby achieving a protective effect and allowing the material to be used longer.
[0003] However, currently when the surface of the material is sprayed, the rotation of the turntable drives the material to rotate. When the material rotates, the fixed nozzles on both sides spray the spray agent on the surface of the material, and the spray from the nozzle is in the form of mist. The characteristic of the mist is that the spraying force in the center is greater than the force around the mist, which results in that at the same time, the accumulation thickness of the spray aimed at the center of the material is greater than the thickness at the edge of the material, resulting in uneven spraying on the surface of the material. Utility Model Content
[0004] In view of the deficiencies of the prior art, the utility model provides an automatic spraying device for pulp molding, which solves the problems raised by the above-mentioned background technology.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-5 , the present utility model provides a technical solution: a pulp molding automatic spraying device, including a bracket 1. The upper end of the bracket 1 is fixedly connected with a spraying box body 2. A spray head 3 is arranged at the upper end of the spraying box body 2. Driving mechanisms are arranged on both sides of the upper end of the spraying box body 2. The driving mechanisms include: a fixed strip 4. A limit chute 5 is opened at the upper end of the fixed strip 4. A threaded rod 6 is fixedly connected in one of the limit chutes 5. A guide rod 7 is fixedly connected in the other limit chute 5. A slide plate 10 is threadedly connected to the threaded rod 6. The slide plate 10 is also slidably connected to the guide rod 7. The spray head 3 is arranged at the upper end of the slide plate 10 in a matching connection manner. An installation plate 8 is fixedly connected to the outer end of the fixed strip 4 where the threaded rod 6 is located. A motor 9 is fixedly connected to the upper end of the installation plate 8. The output end of the motor 9 is fixedly connected to the threaded rod 6. A connecting rod 14 is fixedly connected between the two slide plates 10; a stable frame is formed through the bracket 1. The spraying box body 2 is fixedly connected to the upper end of the frame. A movable spray head 3 is arranged at the upper end of the spraying box body 2. The spray head 3 sprays the coating and sprays it on the material in opposite directions on both sides centered on the spray head 3, so that it can be stably sprayed on the material through the center of the spray head 3, avoiding uneven spraying of the sprayed material on the material. And the specific moving mode of the spray head 3 is that the motor 9 drives the threaded rod 6 to rotate. The motor 9 can rotate forward and backward and is controlled by a controller. The threaded rod 6 rotates forward and backward following the output end of the motor 9, thereby driving the slide plate 10 to move back and forth at the upper end of the fixed strip 4. The spray head 3 connected to the upper end of the slide plate 10 moves back and forth accordingly. The two slide plates 10 move together through the connecting rod 14. A guide rod 7 is fixedly connected in the fixed strip 4 at the other end. The slide plate 10 is slidably guided by the guide rod 7, so that the two slide plates 10 can move back and forth synchronously, thereby driving the spray head 3 to move back and forth, evenly spraying the coating on the material. And the material itself rotates through the turntable at the lower end, cooperating with the moving spray head 3 for uniform spraying, so that the surface of the material is sprayed with a uniform sprayed material.
[0023] As Figure 3As shown in the figure, a connection card 15 is slidably connected to the connecting rod 14. A clamping plate 16 is fixedly connected to the upper end of the outer side of the connection card 15. A clamping groove 12 is formed at the outer end of the clamping plate 16. The inner diameter of the clamping groove 12 is matched with the pipe diameter of the spray head 3. The connection card 15 slidably connected to the connecting rod 14 can move according to the bending degree of the pipeline position. A clamping groove 12 is formed on the outer side surface of the clamping plate 16 fixedly connected to the upper end of the connection card 15. The connecting pipe of the spray head 3 is clamped in the clamping groove 12, thereby avoiding the influence of the connecting pipe body on the spraying of the spray head 3.
[0024] As Figure 5 shown in the figure, a groove 11 is formed at the lower end of the sliding plate 10. A ball 13 is rotatably connected to the upper end of the inner side wall of the groove 11. The ball 13 abuts against the upper end surface of the fixing strip 4. The groove 11 is clamped on the inner edge of the fixing strip 4. A ball 13 is rotatably connected to the upper end of the inner side of the groove 11. When the sliding plate 10 moves, it can slide through the ball 13 and the upper end of the fixing strip 4, which can improve the smoothness of the movement of the sliding plate 10.
[0025] As Figure 3 shown in the figure, the cross-section of the connecting rod 14 is circular, and the number of the connecting rods 14 is two, which are symmetrically arranged at the upper end of the sliding plate 10. The circular connecting rod 14 can reduce the resistance for the sliding of the connection card 15, and the symmetrically arranged connecting rods 14 can provide stable support for the connection card 15, and the connection between the sliding plates 10 is also more stable.
[0026] As Figure 4 shown in the figure, the spray head 3 is rotatably connected to the upper end of the sliding plate 10 through a fixing button. The spraying angle of the spray head 3 is fixed through the fixing button. The upper end of the sliding plate 10 is inclined. The spray head 3 is clamped on the upper end of the sliding plate 10. The spray head 3 is limited and fixed by rotating the fixing button on the side of the sliding plate 10, thereby achieving the effect of fixing the spray head 3.
[0027] As Figure 5 shown in the figure, the balls 13 are symmetrically arranged on the inner side of the groove 11. The symmetrically arranged balls 13 can improve the sliding effect of the sliding plate 10.
[0028] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content within the scope of the technical solution of the present invention to make equivalent embodiments of equivalent changes, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
