Description

Technical Field

[0001] The utility model relates to the field of feeding equipment, and more specifically, to a feeding device for the production of chlorinated polyethylene rubber dedicated to EVA cast film. Background Art

[0002] Chlorinated polyethylene (EVA) rubber dedicated to EVA cast film is a specific material used to manufacture EVA cast film. During the production of EVA cast film, the feeding device is an essential piece of equipment. Its main function is to transport the EVA raw materials to the feeding port of the casting machine to ensure the continuous supply of raw materials during the production process. It can automatically transport the EVA raw materials from the storage bin or container to the feeding port of the casting machine, realizing a continuous production process, which is crucial for ensuring the continuity, stability, and efficiency of the production process.

[0003] However, most of the current feeding devices for the production of chlorinated polyethylene rubber dedicated to EVA cast film have the following problems:

[0004] In the existing feeding devices for the production of chlorinated polyethylene rubber dedicated to EVA cast film, when transporting materials, most directly add raw materials all at once. The addition of raw materials cannot be controlled. During processing, a large amount of raw materials accumulate, which easily affects the quality and efficiency of the production of chlorinated polyethylene rubber. It requires workers to control the amount of raw materials later, and the feeding is rather troublesome and inconvenient for equidistant addition of raw materials. At the same time, when adding raw materials, the amount of raw materials added cannot be controlled, and most directly discharge the raw materials. Adding too much or too little raw materials easily affects the production quality of the materials. Most require workers to repeatedly add materials, resulting in low work efficiency and inability to conveniently adjust the amount of materials added.

[0005] Therefore, we make improvements and propose a feeding device for the production of chlorinated polyethylene rubber dedicated to EVA cast film. Summary of the Utility Model

[0006] The purpose of the present utility model is to address the problems of inconvenient equidistant addition of raw materials and inability to conveniently adjust the amount of materials added currently.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions:

[0008] A feeding device for the production of chlorinated polyethylene rubber dedicated to EVA cast film to improve the above problems.

[0009] Specifically, this application is as follows:

[0010] It includes a protective box, on which a protective outer shell is fixedly connected. On the protective outer shell, a first servo motor is fixedly connected. The output shaft of the first servo motor is fixedly connected with a first transmission gear, which meshes with a second transmission gear. The second transmission gear is fixedly connected with a connecting shaft, and the connecting shaft is rotatably connected to the protective box. The connecting shaft is fixedly connected with a material distribution box, on which a second servo motor is fixedly connected. The output shaft of the second servo motor is fixedly connected with a connecting rod, and the connecting rod is rotatably connected inside the material distribution box. The connecting rod is fixedly connected with a first bevel gear, which meshes with a second bevel gear. The second bevel gear is fixedly connected with a threaded rod, and the threaded rod is rotatably connected to the material distribution box. A threaded sleeve is threadedly connected to the threaded rod, and the threaded sleeve is fixedly connected with a partition plate. A material distribution groove is formed inside the material distribution box, and a guide rod is fixedly connected to the partition plate. The guide rod is slidably connected to the inside of the material distribution box in a limited manner. A transparent acrylic plate is fixedly connected to the material distribution box, an observation window is formed on the protective box, and a material box is fixedly connected to the protective box.

[0011] As a preferred technical solution of the present application, the output shaft of the first servo motor is fixedly connected to the central part of the first transmission gear, and the center line of the first transmission gear and the center line of the second transmission gear are on the same vertical line.

[0012] As a preferred technical solution of the present application, the second bevel gears are distributed at equal angles on the first bevel gear, and the second bevel gears and the threaded sleeves are in one-to-one correspondence through the threaded rods.

[0013] As a preferred technical solution of the present application, the side end face of the partition plate is in contact with the inner side face of the material distribution groove, and the guide rods are arranged on the left and right sides of the partition plate.

[0014] As a preferred technical solution of the present application, a connecting frame is fixedly connected to the protective box, and a sealing gasket is fixedly connected inside the protective box. The side end face of the sealing gasket is in contact with the outer side face of the material distribution box.

[0015] As a preferred technical solution of the present application, the inner bottom end face of the material box is inclined, and the cross section of the connecting frame is in an "L" shape.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] In the solution of the present application:

[0018] 1. There is a material distribution box; when adding materials intermittently, the raw materials can be added to the material box, and the materials can fall into the material distribution groove of the material distribution box. When the first servo motor on the protective housing is turned on, the first servo motor can drive the first transmission gear to operate. When the first transmission gear rotates, it can drive the material distribution box to rotate through the cooperation of the second transmission gear and the connecting shaft. The material distribution groove containing materials rotates and displaces, and the material distribution groove without materials moves to the feeding port. When the material distribution groove containing materials moves to the side, it can be sealed and isolated by the gasket to prevent the materials from falling. When the material distribution groove moves to the lower part, the materials can be discharged. The material distribution box continues to rotate to move the material distribution groove without materials to add materials again, realizing intermittent addition of materials and avoiding the impact on production caused by adding a large amount of materials at one time.

[0019] 2. There is a partition; when it is necessary to adjust the amount of material discharged, the second servo motor can be turned on to drive the connecting rod to operate. The connecting rod can drive the second bevel gear to rotate through the first bevel gear. When the second bevel gear rotates, it can drive the threaded rod to rotate at the same time. When the threaded rod rotates, it can push the threaded sleeve to move. The threaded sleeve adjusts the position of the partition to reduce the space in the material distribution groove. When the partition moves, it can move smoothly under the support and guidance of the guide rods on both sides. When using the equipment, scale lines can be set in the material distribution groove in advance to facilitate the staff to observe the situation in the material distribution groove through the observation window and the transparent acrylic plate, so as to control the amount of material feeding respectively and facilitate adjustment according to the processing and production situation.
