Description

Technical Field

[0001] The utility model relates to the field of epoxy molding compound crushing, in particular to a device for coarsely crushing epoxy molding compound sheets. Background Art

[0002] After the epoxy plastic encapsulating material is extruded and pressed into tablets, the cooled tablets will be roughly crushed. The coarse crushing device is a double-toothed roller crusher with upper and lower crushing teeth arranged crosswise. During the working process, the material enters the crushing teeth evenly from the transmission belt. The material is sheared and crushed by the teeth on the rotating crushing shaft, and naturally falls to the material transfer port and then to the transmission belt to enter the next process.

[0003] However, the plastic encapsulation materials currently produced have high hardness. During the crushing process, the crushing teeth are in direct contact with the material, and wear and damage of the crushing teeth are inevitable. At present, there are three types of damage to the crushing teeth: abrasive wear and thermal fatigue wear. Among them, abrasive wear during the working process will increase the risk of metal content in the epoxy plastic encapsulation material, and thermal fatigue wear will cause the material to have the risk of aging at random points, resulting in poor quality of the produced epoxy plastic encapsulation material. At the same time, excessive consumption during the use of the crushing teeth increases the production cost. How to invent a coarse crushing device for epoxy plastic encapsulation material sheets to improve these problems has become a problem that technicians in this field need to solve urgently.

Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. 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.

[0025] Please refer to Figure 1 and Figure 2 The present utility model provides a technical solution: a rough crushing device for epoxy encapsulant sheets, comprising

[0026] a breaking drive mechanism 100, which includes a drive motor 110 and a housing 120; a crushing mechanism 200, which includes a crushing assembly 210 and a cooling assembly 220. The crushing assembly 210 is installed inside the housing 120, the drive motor 110 is in transmission connection with the crushing assembly 210. The crushing assembly 210 includes a lower crushing rod 211 and an upper crushing rod 212, and threads are provided on the lower crushing rod 211 and the upper crushing rod 212. A blanking assembly 230 is provided at the bottom of the housing 120, and the blanking assembly 230 is arranged corresponding to the crushing assembly 210. The cooling assembly 220 is used to cool the crushing assembly 210, and at the same time the blanking assembly 230 is used to convey the material out.

[0027] In the twin-screw extruder used in the extrusion process, the screw adopts a "building block" design. The screw elements, kneading blocks, retaining rings, etc. on the screw are all wear-resistant components made of GT35 that can be combined and disassembled. During use, many elements with damaged threads will be eliminated and have nowhere to be used. By installing the eliminated elements with damaged threads on the lower crushing rod 211 and the upper crushing rod 212, they can be recycled, reducing production costs.

[0028] Please refer to Figure 3 and Figure 4, the housing 120 includes a blanking hopper 121. A lower pulverizing housing 122 is fixedly connected above the blanking hopper 121. An upper pulverizing housing 125 is connected in a limited sliding manner above the lower pulverizing housing 122. A feeding hopper 126 is fixedly connected to the top of the upper pulverizing housing 125. An outer edge 123 of the upper pulverizing housing is fixedly connected below the upper pulverizing housing 125. The outer edge 123 of the upper pulverizing housing is fixedly installed on the outer part below the upper pulverizing housing 125. A limiting card 124 is fixedly connected to the outer side of the top of the lower pulverizing housing 122. The bottom of the limiting card 124 is fixedly connected to the top of the lower pulverizing housing 122. Above the limiting card 124 is located above the outer edge 123 of the upper pulverizing housing. The outer edge 123 of the upper pulverizing housing is in limiting abutment with the inner top of the limiting card 124. A limiting slide rod is arranged through between the lower pulverizing housing 122 and the upper pulverizing housing 125, so that the upper pulverizing housing 125 and the lower pulverizing housing 122 are in a vertically up-and-down limiting sliding manner. When there is a harder material between the lower crushing rod 211 and the upper crushing rod 212, the upper crushing rod 212 will drive the upper pulverizing housing 125 to move slightly upward. The slight upward movement of the upper pulverizing housing 125 will tighten the belt between the two connecting wheels 215. The belt has a little ductility to avoid damage to the lower crushing rod 211 and the upper crushing rod 212. At the same time, the damping spring will press down the upper pulverizing housing 125 so that the upper pulverizing housing 125 is always in close fit with the lower pulverizing housing 122, facilitating the lower crushing rod 211 and the upper crushing rod 212 to crush the material. The limiting card 124 is arranged in a U shape. Damping springs are arranged in an equally divided manner on the inner top of the limiting card 124. The other ends of the damping springs are fixedly installed on the top of the outer edge 123 of the upper pulverizing housing.

[0029] The crushing assembly 210 further includes a transmission connecting rod 213. The transmission connecting rods 213 are respectively fixedly connected to both ends of the lower crushing rod 211 and the upper crushing rod 212. The transmission connecting rods 213 at both ends of the lower crushing rod 211 respectively pass through the lower pulverizing housing 122 in a limited rotation manner. The transmission connecting rods 213 at both ends of the lower pulverizing housing 122 respectively pass through the upper pulverizing housing 125 in a limited rotation manner. Transmission wheels 214 and connecting wheels 215 are respectively fixedly sleeved on the transmission connecting rods 213 at both ends of the lower crushing rod 211. A connecting wheel 215 is fixedly sleeved on the transmission connecting rod 213 at one end of the upper crushing rod 212. The two connecting wheels 215 are arranged parallel to each other up and down. A driving wheel 216 is fixedly connected to the end of the driving motor 110. The driving wheel 216 and the transmission wheel 214 are connected by multiple groups of belts. Belts are equally divided and sleeved on the two groups of connecting wheels 215. The lower crushing rod 211 and the upper crushing rod 212 are arranged in a staggered manner to improve the crushing effect.

[0030] The cooling component 220 includes an output pipe 221 and an input pipe 222. The middle parts of the lower crushing rod 211, the upper crushing rod 212, and the transmission connecting rod 213 are hollow. The output pipe 221 and the input pipe 222 are respectively limited and rotatably sleeved on the transmission connecting rod 213 at one end. The ends of the two groups of transmission connecting rods 213 at the other end are limited and rotatably communicated with a connecting pipe 223. The two ends of the connecting pipe 223 are respectively fixedly connected to the side walls of the upper crushing shell 125 and the lower crushing shell 122. When the output pipe 221, the input pipe 222, and the connecting pipe 223 are all detachable, they are all hermetically and rotatably connected to the transmission connecting rod 213 through a sealing rotating element, which facilitates the circulation of the internal water.

[0031] The feeding component 230 includes a feeding pipe 231. The feeding pipe 231 is fixedly installed at the bottom of the feeding hopper 121. A auger 232 is rotatably installed inside the feeding pipe 231. The end of the auger 232 is fixedly connected with a matching transmission wheel 233. The matching transmission wheel 233 is in transmission connection with the transmission wheel 214. At least two groups of feeding components 230 are provided, and the two groups are symmetrically arranged on both sides of the housing 120.

[0032] Working principle: The material is conveyed into the upper hopper 126. At the same time, the driving motor 110 drives the lower crushing rod 211 and the upper crushing rod 212 to rotate to crush the incoming material. At the same time, the input pipe 222 is communicated with an external water source, and the water passes through the lower crushing rod 211 and the connecting pipe 223 and enters the upper crushing rod 212 and is discharged from the output pipe 221. The ends of the output pipe 221, the input pipe 222, and the connecting pipe 223 are all limited and hermetically rotatably connected to the transmission connecting rod 213. The crushed material falls onto the feeding hopper 121 and slides into the feeding pipe 231. When the driving motor 110 drives the driving wheel 216, it drives the connecting pipe 223 to rotate through the transmission wheel 214 at the same time, so that the auger 232 drives the material to be discharged.

[0033] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
