Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, and more specifically, to a grinding device for the production of EVA slippers. Background Technology

[0002] The material used in EVA slippers is ethylene / vinyl acetate copolymer, also known as ethylene-vinyl acetate copolymer, which is made by copolymerizing ethylene and vinyl acetate. Therefore, in the production and processing of EVA slippers, it is necessary to use a grinding device to grind the ethylene and vinyl acetate raw materials to ensure the stability of subsequent injection molding.

[0003] Currently, most grinding equipment used in EVA slipper production has the following problems:

[0004] I. Existing grinding equipment used in EVA slipper production often grinds materials of varying sizes, which can lead to uneven grinding and substandard results. This necessitates collection and secondary grinding, resulting in poor performance and inconvenience in fully grinding the materials.

[0005] Second, in the existing grinding equipment used for EVA slipper production, some large particles are easily present in the powder after grinding. Most of the materials are filtered and screened through a filter screen. After screening, the large particles are easy to clog the filter screen, affecting the subsequent material filtration effect and making it inconvenient to filter the materials conveniently.

[0006] Therefore, we have made improvements to this and proposed a grinding device for the production of EVA slippers. Utility Model Content

[0007] The purpose of this utility model is to address the current problems of inconvenience in fully grinding materials and inconvenient filtration of materials.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A grinding device for EVA slipper production was developed to improve the aforementioned problems.

[0010] The application is as follows:

[0011] The device includes a housing, on which a first motor is fixedly connected. The output shaft of the first motor is fixedly connected to a connecting shaft, which is rotatably connected inside the housing. A first grinding block is fixedly connected to the connecting shaft. A first grinding frame is fixedly connected inside the housing. A pulverizing block is fixedly connected to both the first grinding block and the first grinding frame. A second grinding block is fixedly connected to the connecting shaft. A second grinding frame is fixedly connected inside the housing. A spring is fixedly connected inside the second grinding frame. A limit plate is fixedly connected to the other end of the spring. A connecting rod is fixedly connected to the limit plate. A filter screen is fixedly connected to the other end of the connecting rod. A push plate is fixedly connected to the limit plate. A fixing frame is fixedly connected to the housing. A second motor is fixedly connected to the fixing frame. A push block is fixedly connected to the output shaft of the second motor. A sealing cover is bolted to the housing.

[0012] As a preferred technical solution of this application, the connecting shaft is fixedly connected to the center of the first grinding block, and the top surface of the first grinding block is inclined to the inner surface of the first grinding frame.

[0013] As a preferred technical solution of this application, the crushing blocks are distributed at equal angles on the first grinding block and the first grinding frame, and the gap between the second grinding block and the second grinding frame gradually decreases from top to bottom.

[0014] As a preferred technical solution of this application, the springs are distributed at equal angles within the second grinding frame, and the springs correspond one-to-one with the connecting rods through limiting plates.

[0015] As a preferred technical solution of this application, the filter screen has an inclined cross-section, and the pusher block has a teardrop-shaped cross-section.

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

[0017] In the scheme of this application:

[0018] 1. A first grinding block is provided; when grinding polypropylene granules into powder, the material can be added into the outer shell of the device and guided by the inclined surface of the first grinding frame. The first motor is turned on to drive the connecting shaft to rotate. The first grinding block and the crushing block on the first grinding frame can crush larger materials and continue to move downwards. The cooperation between the first grinding block and the first grinding frame can grind the material into powder. After grinding, the powder falls to the bottom and is guided by the inclined surface of the second grinding block to fall into the second grinding frame. The cooperation between the second grinding block and the second grinding frame can perform secondary grinding, improve the grinding effect and quality, and avoid re-collection and secondary grinding.

[0019] 2. Equipped with a pusher block; when using a filter screen to sieve the ground powder, to prevent the filter screen from becoming clogged, the second motor on the fixed frame can be turned on. The second motor drives the pusher block to rotate. When the pusher block rotates, its longer end can push the push plate to move upward. When the push plate moves, it can drive the limiting plate to move simultaneously. The limiting plate can compress the spring, and at the same time, the limiting plate pulls the filter screen upward through the connecting rod, lifting the filter screen. When the pusher block rotates rapidly and disengages from the push plate, it is pushed by the spring to drive the limiting plate and connecting rod to reset. When resetting, it can shake the filter screen to shake off the blockages on the filter screen, avoid clogging, and improve the sieving effect. Attached Figure Description

[0035] Example 2:

[0036] The solution in Example 1 will be further described below with reference to its specific working method.

[0037] like Figure 3 As shown, in a preferred embodiment, based on the above method, the connecting shaft 3 is further fixedly connected to the center of the first grinding block 4, and the top surface of the first grinding block 4 is inclined to the inner surface of the first grinding frame 5, which can ensure that the inclined surfaces of the first grinding block 4 and the first grinding frame 5 can guide the material to move.

[0038] like Figure 3 As shown, in a preferred embodiment, based on the above method, the crushing blocks 6 are further distributed at equal angles on the first grinding block 4 and the first grinding frame 5, and the gap between the second grinding block 7 and the second grinding frame 8 gradually decreases from top to bottom, which can ensure that the gap between the second grinding block 7 and the second grinding frame 8 can fully grind larger materials.

[0039] like Figure 5 As shown, in a preferred embodiment, based on the above method, the springs 9 are further distributed at equal angles within the second grinding frame 8, and the springs 9 correspond one-to-one with the connecting rods 11 through the limiting plate 10, which can ensure that the multiple connecting rods 11 can pull the filter screen 12 to move smoothly.

[0040] like Figure 7 As shown, in a preferred embodiment, based on the above method, the filter screen 12 has an inclined cross-section and the pusher block 16 has a teardrop-shaped cross-section, which can ensure that the longer end of the teardrop-shaped pusher block 16 can push the pusher plate 13 to move.

[0041] Specifically, when using this grinding device for EVA slipper production: (in conjunction with...) Figure 1-7 When grinding polypropylene granules into powder, the material can be added into the outer shell 1 of the device and guided by the inclined surface of the first grinding frame 5. The first motor 2 is turned on to drive the connecting shaft 3 to rotate. The first grinding block 4 and the crushing block 6 on the first grinding frame 5 can crush larger materials and continue to move downwards.
