Description

Technical Field

[0001] This utility model relates to the technical field of rubber crushing devices, specifically a rubber crushing device for rubber shoe production. Background Technology

[0002] Rubber shoes consist of a rubber sole and a rubber upper. The rubber sole is made of rubber, and the materials for rubber soles can be broadly divided into natural rubber and synthetic rubber. The advantage of natural rubber lies in its softness and excellent elasticity, making it suitable for various sports and providing shock absorption. The production of rubber soles requires the crushing of various raw materials.

[0003] Chinese patent CN214871940U discloses a rubber crushing device for rubber shoe production. This technical solution uses the output shaft of a drive motor to rotate a stirring rod, which in turn drives multiple stirring blades to rotate and mix various raw materials at the top of the first hopper evenly. The rotation of the stirring rod also drives the crushing rod to rotate, which in turn drives multiple crushing blades to rotate and crush the raw materials at the top of the second hopper. The rotation of the crushing rod drives the rotating rod to rotate, which in turn drives two cams to rotate and intermittently collide with the screen plate, so that the crushed and qualified raw materials at the top of the screen plate can fall quickly into the receiving box.

[0004] However, the rubber crushing device used in the production of rubber shoes generates waste gas and dust during the crushing and screening process, which affects the surrounding environment and may cause certain health hazards to the workers around the device, thus hindering the production and processing of rubber shoes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rubber crushing device for rubber shoe production, which solves the problem that the waste gas and dust generated by the rubber crushing device in rubber shoe production will affect the surrounding environment.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a rubber crushing device for rubber shoe production, including a crushing box, a collection bucket placed at the bottom of the inner wall of the crushing box, and a linkage mechanism for crushing and screening rubber provided in the upper part of the inner cavity of the crushing box.

[0007] The top of the crushing box is connected to several feeding hoppers, the middle of the inner cavity of the crushing box is fixedly connected to a dust collection plate, the side wall of the crushing box is fixedly connected to a purification box, and the top of the inner cavity of the purification box is equipped with a fan. The air inlet of the fan is connected to the dust collection plate through an air inlet pipe.

[0008] The air outlet of the fan is detachably fitted with a dust collection bag, the bottom of the purification box is provided with an exhaust window, and the bottom of the inner cavity of the purification box is fixedly connected with an activated carbon plate.

[0009] Furthermore, a limiting block is fixedly connected to the top of the inner wall of the feed hopper, and a cover plate is placed on the top of the limiting block, with an air inlet window provided on the cover plate.

[0010] Furthermore, the front side of the crushing box is provided with a material handling door adapted to the collection bucket, and the material handling door is provided with an observation window.

[0011] Furthermore, a base is fixedly connected to the bottom of the crushing box, and the bottom of the base has several mounting holes.

[0012] Furthermore, the linkage mechanism includes a crushing rod, a sieve plate, and a rotating rod. The crushing rod is rotatably disposed at the top of the inner cavity of the crushing box. The sieve plate is slidably disposed in the upper part of the inner cavity of the crushing box in a vertical direction. The rotating rod is rotatably disposed in the inner cavity of the crushing box and located below the sieve plate. Both ends of the rotating rod surface are rotatably disposed with a beating wheel that can contact the lower surface of the sieve plate.

[0013] Furthermore, a transmission box is fixedly connected to the side wall of the crushing box. One end of both the crushing rod and the rotating rod extends rotatably into the inner cavity of the transmission box and is fixedly connected to a pulley. The two pulleys are connected by a belt drive. A motor is fixedly connected to the side wall of the transmission box. The output shaft of the motor extends rotatably into the inner cavity of the transmission box and is fixedly connected to one end of the crushing rod.

[0014] Furthermore, a collecting hopper is fixedly connected to the inner cavity of the crushing box, and the collecting hopper is located between the crushing rod and the feeding hopper.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: After rubber is fed into the crushing box through the feeding hopper, the crushing rod can crush the rubber. After crushing, the crushed rubber is screened through the screening plate. During the screening process, the rotating rod drives the beater wheel to intermittently contact the lower surface of the screening plate, which can improve the screening efficiency of the screening plate. In addition, during the crushing and screening process, after the fan is working, the dust collection disc generates negative pressure through the air inlet pipe, which sucks up the waste gas and dust in the crushing box and discharges them into the inner cavity of the dust collector bag. The dust collector bag filters the dust in the waste gas, and the exhaust window filters the harmful substances in the waste gas. The purified airflow is discharged through the exhaust window, avoiding the impact of the generated waste gas and dust on the surrounding buffer of the device, improving the protection of the health of the personnel around the device, and facilitating the production and processing of rubber shoe soles.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a rubber crushing device for rubber shoe production, including a crushing box 1, a collection bucket 4 placed at the bottom of the inner wall of the crushing box 1, and a linkage mechanism for crushing and screening rubber provided at the upper part of the inner cavity of the crushing box 1.

[0022] The top of the crushing box 1 is connected to several feeding hoppers 5. A dust collection disc 14 is fixedly connected to the middle of the inner cavity of the crushing box 1. A purification box 15 is fixedly connected to the side wall of the crushing box 1. A fan 16 is installed at the top of the inner cavity of the purification box 15. The air inlet of the fan 16 is connected to the dust collection disc 14 through the air inlet pipe 17.

[0023] The outlet of the fan 16 is fitted with a dust collection bag 18, the bottom of the purification box 15 is provided with an exhaust window 20, and the bottom of the inner cavity of the purification box 15 is fixedly connected with an activated carbon plate 19.

[0024] The linkage mechanism includes a crushing rod 7, a screening plate 12, and a rotating rod 9. The crushing rod 7 is rotatably disposed at the top of the inner cavity of the crushing box 1, and the screening plate 12 is slidably disposed at the upper part of the inner cavity of the crushing box 1 in the vertical direction.

[0025] The rotating rod 9 is rotatably disposed in the inner cavity of the crushing box 1 and located below the screening plate 12. Both ends of the surface of the rotating rod 9 are rotatably provided with a beating wheel 13 that can contact the lower surface of the screening plate 12.

[0026] After the rubber is fed into the crushing box 1 by the feed hopper 5, the rubber can be crushed by the crushing rod 7. After crushing, the crushed rubber is screened by the screening plate 12.

[0027] During the screening process, the rotation of the rotating rod 9 causes the beater wheel 13 to intermittently contact the lower surface of the screening plate 12, thereby improving the screening efficiency of the screening plate 12.

[0028] During the crushing and screening process, after the blower 16 is working, the dust collection disc 14 generates negative pressure through the connection of the air inlet pipe 17, which sucks up the exhaust gas and dust in the inner cavity of the crushing box 1 and discharges them into the inner cavity of the dust collector bag 18. After the dust collector bag 18 filters the dust in the exhaust gas, the exhaust window 20 filters the harmful substances in the exhaust gas.

[0029] The purified airflow is discharged through the exhaust window 20, which avoids the generated exhaust gas and dust from affecting the surrounding buffer of the device, improves the protection of the personnel around the device, and is conducive to the production and processing of rubber shoe soles.

[0030] A limiting block 21 is fixedly connected to the top of the inner wall of the feed hopper 5. A cover plate 22 is placed on the top of the limiting block 21, and an air inlet 23 is provided on the cover plate 22.

[0031] The upper surface of the cover plate 22 is provided with a handle. The cover plate 22 prevents foreign objects from entering the inner cavity of the feed hopper 5. The air inlet window 23 facilitates the balance of pressure in the inner cavity of the crushing box 1.

[0032] The front side of the crushing box 1 is provided with a material receiving door 24 that is compatible with the collection bucket 4. The material receiving door 24 is provided with an observation window. After opening the material receiving door 24, the collection bucket 4 can be taken out, which facilitates the material receiving of finished rubber.

[0033] The bottom of the crushing box 1 is fixedly connected to a base 2, and the bottom of the base 2 has several mounting holes 3.

[0034] A transmission box 8 is fixedly connected to the side wall of the crushing box 1. One end of the crushing rod 7 and the rotating rod 9 both extend rotatably into the inner cavity of the transmission box 8 and are fixedly connected to a pulley 11. The two pulleys 11 are connected by belt drive. A motor 10 is fixedly connected to the side wall of the transmission box 8. The output shaft of the motor 10 extends rotatably into the inner cavity of the transmission box 8 and is fixedly connected to one end of the crushing rod 7.

[0035] After the motor 10 starts working, it drives the crushing rod 7 to rotate, which can then carry out crushing processing. During the crushing process, the two pulleys 11 and the belt drive the rotating rod 9 to rotate, which in turn drives the beater 13 to intermittently contact the lower surface of the screening plate 12, causing the screening plate 12 to vibrate and accelerate the screening efficiency.

[0036] The inner cavity of the crushing box 1 is fixedly connected to a collecting hopper 6, which is located between the crushing rod 7 and the feeding hopper 5.

[0037] During operation, rubber is fed into the crushing box 1 through the feed hopper 5, and then crushed by the crushing rod 7. After crushing, the crushed rubber is screened by the screening plate 12. During the screening process, the rotating rod 9 rotates, causing the beater wheel 13 to intermittently contact the lower surface of the screening plate 12, which improves the screening efficiency of the screening plate 12. During the crushing and screening process, after the blower 16 is working, the dust suction plate 14 generates negative pressure through the air inlet pipe 17, sucking up the exhaust gas and dust in the inner cavity of the crushing box 1 and discharging them into the inner cavity of the dust collector bag 18. The dust collector bag 18 filters the dust in the exhaust gas, and the exhaust window 20 filters the harmful substances in the exhaust gas. The purified airflow is discharged through the exhaust window 20, avoiding the impact of the generated exhaust gas and dust on the surrounding buffer of the device.
