Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model discloses a rubber crushing equipment for rubber shoe production, comprising a crushing equipment body 1, an inlet 2 at the upper end of the crushing equipment body 1, an outlet 3 at the lower end of the crushing equipment body 1, two drive rollers 14 symmetrically arranged at the inlet 2 above the crushing equipment body 1, a fixed shaft 13 fixedly arranged at the center of the drive rollers 14, and fixed frames 5 at both ends of the fixed shaft 13, a support rod 4 at the lower end of the fixed frame 5, a plurality of limiting shafts 9 symmetrically arranged on the outer wall of the crushing equipment body 1, and a bushing 15 through which the limiting shafts 9 pass at the bottom end of the support rod 4, and the bushing 15 is rotatably connected to the limiting shafts 9; a motor 12 is fixedly arranged on the two fixed frames 5 on the same side of the crushing equipment body 1, and the output end of the motor 12 is provided with a drive shaft that passes through the fixed frame 5 and is connected to the fixed shaft 13;

[0025] A lifting assembly 11 is fixedly installed on one side of the main body 1 of the crushing equipment. The output end of the lifting assembly 11 is provided with a drive block 10 that is slidably connected to the main body 1 of the crushing equipment. The drive block 10 is located between the two bushings 15 and engages with the bushings 15 on both sides of it.

[0026] In this embodiment, the lifting assembly 11 is a telescopic cylinder, and the motor 12 is a servo motor.

[0027] In this embodiment, the lower end of the fixing frame 5 is provided with a connecting rod 6 that is inserted into the support rod 4. The connecting rod 6 is provided with a plurality of limiting holes 7. The top end of the support rod 4 is provided with a locking rod 8 that passes through the limiting holes 7, which makes it easy to adjust the height of the drive roller 14.

[0028] In this embodiment, the locking rod 8 is threadedly connected to the support rod 4, which makes the locking rod 8 more securely installed.

[0029] In this embodiment, the outer wall of the drive roller 14 is provided with anti-slip texture.

[0030] Place the main body of the crushing equipment 1 in a suitable working position to ensure that the equipment is stable;

[0031] Above the main body 1 of the crushing equipment, two drive rollers 14 are installed at the symmetrical feed inlets 2. The specific operation is as follows: first, fix the fixed shaft 13 at the center of the drive roller 14, then install the fixing brackets 5 at both ends of the fixed shaft 13. The lower end of the fixing bracket 5 is provided with a support rod 4. Connect the support rod 4 to the fixing bracket 5. The connecting rod 6 at the lower end of the fixing bracket 5 is inserted into the support rod 4 so that the limiting hole 7 on the connecting rod 6 is aligned with the top of the support rod 4. Then, the locking rod 8 passes through the limiting hole 7 and is threadedly connected to the support rod 4, thereby realizing a stable connection between the fixing bracket 5 and the support rod 4.

[0032] Multiple limiting shafts 9 are symmetrically installed on the outer wall of the main body 1 of the crushing equipment. The bushing 15 at the bottom of the support rod 4 is installed on the limiting shaft 9, and the bushing 15 and the limiting shaft 9 are rotatably connected.

[0033] Motors 12 are installed on two fixed frames 5 on the same side of the main body 1 of the crushing equipment. The output drive shaft of the motor 12 passes through the fixed frame 5 and is connected to the fixed shaft 13. Here, the motor 12 is a servo motor so as to accurately control the speed and rotation of the drive roller 14.

[0034] A lifting assembly 11 is installed on one side of the main body 1 of the crushing equipment. In this embodiment, the lifting assembly 11 adopts a telescopic cylinder. The output end of the telescopic cylinder is connected to the drive block 10. The drive block 10 is slidably connected to the main body 1 of the crushing equipment, and the drive block 10 is located between two bushings 15 and engages with the bushings 15 on both sides.

[0035] First, place the rubber block to be crushed above the feed inlet 2. Then, activate the lifting assembly 11, which will cause the drive block 10 to move upward. At this time, through meshing, the two bushings 15 will rotate synchronously and in opposite directions around the two limit shafts 9, allowing the two drive rollers 14 to move above the feed inlet 2 on both sides of the crushing equipment body 1 (e.g., Figure 1 As shown), at this time, the two drive rollers 14 will squeeze the rubber block to be shredded, and further start the servo motor. The two servo motors drive the two fixed shafts 13 to rotate synchronously in opposite directions through the two drive shafts, thereby making the two drive rollers 14 rotate synchronously in opposite directions. The anti-slip texture on the outer wall of the drive roller 14 can increase the friction with the rubber, and more effectively grasp the rubber block, so that the large piece of rubber can be placed into the feed port 2 at a uniform speed. Then, the rubber block is shredded by the crushing shaft in the main body of the crushing equipment 1. The shredded rubber block will be discharged through the discharge port 3. This process does not require manual continuous feeding of rubber blocks, which has a high safety factor. It can also prevent large pieces of rubber from accumulating in the feed port 2, and will not cause the rubber block to block in the feed port 2. This makes the main body of the crushing equipment 1 more stable during operation.

[0036] By engaging the locking rod 8 with the limiting hole 7, the docking rod 6 can be fixed. The locking rod 8 can be pulled out and inserted into the designated limiting hole 7, which facilitates temporary adjustment of the height of the drive roller 14. The distance between the two drive rollers 14 can also be freely adjusted, making it convenient to feed rubber blocks of different thicknesses and lengths, with strong applicability.
