Description

Technical Field

[0001] The invention relates to the technical field of butyl rubber hot-melt, in particular to butyl rubber hot-melt pretreatment equipment. Background Art

[0002] Butyl rubber is a type of synthetic rubber, synthesized from isobutylene and a small amount of isoprene. It is generally used to make tires. At the same time, existing butyl rubber is also used in the production of butyl waterproof tape. It needs to be melted and stirred as a whole using hot melt equipment, and then the melted butyl rubber is extruded through a screw extruder and applied to the surface of the substrate for preparation. Although these steps are the main processing methods for butyl rubber at present, they still have obvious defects in actual use, such as: In order to facilitate transportation, existing butyl rubber blocks are usually made into large square blocks, which are directly placed in the hot melt mixer during hot melting. However, butyl rubber itself has a high hardness, which makes the hot melting efficiency extremely slow. It takes a long time to completely soften it for use. At the same time, dust and impurities will adhere to the surface of butyl rubber blocks during loading and transportation. If they are directly put into hot melting, impurities will be mixed in, resulting in a decrease in quality. Therefore, a butyl rubber hot melt pretreatment equipment that can improve hot melt efficiency and quality is now designed to solve such defects. Summary of the invention

[0014] The present invention provides a butyl rubber hot melt pretreatment device. Compared with the existing technology, it has the following beneficial effects: (1) The butyl rubber hot melt pretreatment equipment combines a cleaning and drying mechanism and a cutting and feeding mechanism. The two mechanisms can utilize the lifting and lowering of the cylinder to first drive the cutting blade to pressurize and cut the butyl rubber block, then rinse it, and allow the material holding frame to salvage the rinsed butyl rubber block. Subsequently, by utilizing the linkage between the structures, the inclined guide plate pushes the material holding support plate to flip and dock, so that the butyl rubber block falls on the top of the mesh conveyor belt for drying, thereby ensuring that the subsequent butyl rubber block is quickly hot-melted and reduces impurities, which satisfies the current use.

[0015] (2) The butyl rubber hot melt pretreatment equipment has a feed conveyor installed inside a cutting box, and rectangular grooves are opened on the top and bottom of the feed conveyor. It is used in conjunction with a cutting blade, a gear cylinder and a load-bearing support plate. The arrangement of these structures can first place a large block of butyl rubber on the inner side of the rectangular groove, and then use the force of the upper frame pressing down to push the cutting blade to press and divide the butyl rubber block into small blocks. After the subsequent retraction frame rises, it can also use the meshing with the gear cylinder to drive the feed conveyor to load and unload the material, which not only ensures that the butyl blocks after cutting are of the same size, which is convenient for hot melting, but also improves the overall efficiency.

[0016] (3) The butyl rubber hot melt pretreatment equipment is used by installing a material holding frame and a mixing drum inside the rinsing tank, and is used in combination with an inclined guide frame, a cross bar and an inclined guide plate. The arrangement of these structures can use the rotating mixing drum to drive the butyl blocks to be cleaned, and then fish them out through the material holding frame. In the process of rising, the inclined guide frame squeezes the inclined guide plate to drive the material holding support plate to reverse and connect at an angle, so that the butyl blocks can be placed on the top of the mesh conveyor. The whole process does not require manual operation by the staff to complete the catching and unloading of the materials, which is convenient for use.

[0017] (4) The butyl rubber hot melt pretreatment equipment is used by arranging a mesh conveyor belt and a hot blower inside the drying box, and using it in conjunction with a material guide inclined frame. The arrangement of these structures can use the mesh conveyor belt to drain the wet butyl blocks, and use the hot blower to increase the temperature inside the drying box to dry them, and finally use the material guide inclined frame to discharge the materials, thereby ensuring the quality and quality of the hot melt.

The end of the first rotating rod 104 extending to the front of the cutting box 102 is fixedly connected to the gear cylinder 112. The arc-shaped tooth plate 219 and the gear cylinder 112 are preset. Each rotation will drive the material conveyor belt 106 to move a constant distance, so that the rectangular groove 107 is always located below the cutting blade 109, and the inner cavity of the cutting box 102 is fixedly connected to the gear cylinder 112. A load-bearing support plate 113 used in conjunction with the material conveyor belt 106 is fixedly connected between the front and rear parts of the cutting box 102. Rebound rods 108 are slidably installed on the front and rear sides of the top of the cutting box 102 through openings. A cutting blade 109 used in conjunction with the rectangular groove 107 is fixedly connected between the bottom ends of the two rebound rods 108 and located on the inner side of the cutting box 102 through a fixed plate. A pressure plate 110 is fixedly connected between the top ends of the two rebound rods 108.

A rectangular push frame 211 is slidably installed on the surface of the positioning slide 210. A second spring 213 is fixedly connected between the positioning slide 210 and the inner wall of the rectangular push frame 211. An inclined guide plate 212 used in conjunction with the mesh conveyor belt 204 is fixedly connected between the two rectangular push frames 211 through a bracket, and the inclined guide plate 212 is located on the inner side of the drying box 201, the right end of the rectangular push frame 211 is fixedly connected to the cross rod 214 through a fixed block, the right side of the drying box 201 is fixedly connected to the cylinder 215 through a fixed seat, the top of the cylinder 215 is fixedly connected to the upper frame 216 through a fixed plate, the bottom of the upper frame 216 is fixedly connected to the inclined guide frame 217 used in conjunction with the cross rod 214 through a bracket, the surface of the upper frame 216 is fixedly connected to the retraction frame 218 through a bracket, the inner side of the retraction frame 218 is slidably installed with an arc-shaped tooth plate 219 meshing with the gear cylinder 112, and a third spring 220 is fixedly connected between the arc-shaped tooth plate 219 and the inner wall of the retraction frame 218, and the left side of the bottom of the upper frame 216 is fixedly connected to the lifting The pulling cylinder 221 has a lifting vertical rod 222 slidably installed at the bottom of the inner cavity of the lifting cylinder 221 through an opening, and the bottom end of the lifting vertical rod 222 is fixedly connected to a material holding frame 223 through a fixing plate, and a fourth spring 224 is sleeved on the surface of the lifting vertical rod 222 and located on the inner side of the lifting cylinder 221, and the bottom of the material holding frame 223 is rotatably connected to a material holding plate 225 through a bearing member, and the rotation point of the material holding plate 225 is not in the middle, but is set on the right side, so that the material holding plate 225 can be flipped and reset by its own weight, and the front and rear sides of the bottom of the material holding plate 225 are fixedly connected to a vertical push rod 226 through a fixing block, and the right side of the bottom of the upper frame 216 is fixedly connected to a pressing column 227 used in conjunction with the pressure plate 110 through a fixing block.
