Description

Technical Field

[0001] This utility model belongs to the field of rubber processing and resource recycling technology, specifically a rubber cutting recycling device. Background Technology

[0002] In the processing of various rubber products, rubber materials often need to be cut. Taking rubber sheets as an example, they usually need to be cut into specific shapes and sizes during production to meet subsequent assembly or usage requirements. To improve cutting efficiency and protect the health of operators, an adjustable rubber sheet cutting device (publication number CN113829410B, publication date August 11, 2023) is disclosed in the prior art. This device cleans rubber shavings adhering to the cutting blades by setting a cleaning component, extending the service life of the blades, and at the same time, it collects and recycles a large amount of rubber powder generated during the cutting process, avoiding the potential health hazards of dust to personnel.

[0003] However, this design primarily focuses on tool cleaning and dust recovery, failing to provide an effective recycling solution for larger waste materials generated during the cutting process (such as scraps or defective products). This limitation results in a narrow recycling scope, making it difficult to fully meet the needs of resource reuse. Therefore, there is a need in the field for a technical solution capable of comprehensively processing cutting waste to achieve more efficient resource recycling. Utility Model Content

The bottom of the guide trough is designed with an inclined structure, allowing the waste material to move along the waste material flow direction and enter the starting end of the conveying mechanism.

[0005] Preferably, the rubber cutting recycling device further includes a pair of side supports, which are fixedly connected to the outer walls of both sides of the collection box and bolted to both ends of the conveying mechanism. Rollers are installed at both ends of the conveying mechanism, and the rollers are mounted in mounting holes next to the side supports via bearings.

[0007] Preferably, the lower end of the material distribution plate is provided with multiple material distribution teeth, which are evenly distributed along the length of the material distribution plate, and the tip of each material distribution tooth is inclined towards the direction of movement of the conveyor belt. The inclination angle of the material distribution teeth is set between 30° and 45° to ensure that the waste material can be evenly dispersed to different areas of the conveyor belt under the action of the material distribution teeth.

[0008] Preferably, the rubber cutting recycling device further includes an adjustment mechanism, which comprises an adjustment screw and a guide rod.

[0024] Example 1

[0025] like Figures 1 to 4 As shown, this utility model provides a recycling device for rubber cutting, including a collection box 1, a conveying mechanism 3, a distributing plate 4, a collection box 5, and multiple auxiliary components. The specific structure, connection relationships, and operation process of each component will be described in detail below with reference to the accompanying drawings.

[0026] The collection box 1 is the starting part of the device, and its interior is equipped with a guide chute 2 extending along the direction of waste material flow. The bottom of the guide chute 2 is designed with an inclined structure, and the inclination angle is set between 10° and 20° according to actual needs to ensure that the waste material can smoothly slide down to the starting end of the conveying mechanism 3 by gravity. The top of the collection box 1 is equipped with a feed inlet, and a flexible sealing strip is installed on the edge of the feed inlet. The flexible sealing strip is fixed to the inner wall of the feed inlet with adhesive, and the material is made of wear-resistant rubber to reduce the impact and wear on the edge of the feed inlet when the waste material enters. A pair of side brackets 6 are fixedly connected to the outer walls of both sides of the collection box 1. The side brackets 6 are connected to both ends of the conveying mechanism 3 by bolts, thereby realizing a stable connection between the collection box 1 and the conveying mechanism 3.

[0027] The conveying mechanism 3 is located downstream of the guide chute 2, with rollers 7 installed at both ends. The rollers 7 are mounted in mounting holes next to the side bracket 6 via bearings. One end of one roller 7 is connected to the output shaft of the drive motor 8 via a coupling. The drive motor 8 is fixedly mounted on the outer surface of the side bracket 6 and drives the roller 7 to rotate, thereby moving the conveyor belt 23. The surface of the conveyor belt 23 is provided with multiple evenly distributed baffles 9, perpendicular to the direction of movement of the conveyor belt 23, and fixed to the conveyor belt 23 by welding. The height of each baffle 9 is set to maintain a certain gap with the lower end of the distribution plate 4, ranging from 5mm to 10mm, to prevent waste from accumulating or clogging during conveying. The conveyor belt 23 is made of anti-slip material, and its surface is provided with multiple raised structures evenly distributed along the width direction of the conveyor belt 23 to increase the friction between the waste and the conveyor belt 23, preventing the waste from sliding during conveying.

[0028] The material distribution plate 4 is located above the conveying mechanism 3 and is fixedly connected to the side wall of the collection box 1 via a support frame. Multiple material distribution teeth 10 are provided at the lower end of the material distribution plate 4. These teeth 10 are evenly distributed along the length of the material distribution plate 4, and the tip of each tooth 10 is inclined towards the direction of movement of the conveyor belt 23 at an angle between 30° and 45°. The design of the material distribution teeth 10 allows waste to be evenly dispersed into different areas of the conveyor belt 23 under the action of the teeth, thereby improving the uniformity of waste distribution. The height of the material distribution plate 4 can be adjusted by an adjustment mechanism 11, which includes an adjustment screw 12 and a guide rod 13. One end of the adjustment screw 12 is threaded to the upper end of the material distribution plate 4, and the other end passes through a threaded hole in the support frame and is fixedly connected to a handwheel 14. One end of the guide rod 13 is fixedly connected to the upper end of the material distribution plate 4, and the other end passes through a guide hole in the support frame, allowing the height of the material distribution plate 4 to be adjusted vertically to accommodate waste recycling needs of different sizes and shapes.

[0029] The collection box 5 is located below the end of the conveying mechanism 3 and is used to receive waste material conveyed from the conveying mechanism 3. Figure 4 As shown, the collection box 5 has a partition 15 inside, which divides the internal space of the collection box 5 into multiple storage areas. Each storage area has a removable base plate 16 at its bottom. The base plate 16 is connected to the collection box 5 by a snap-fit ​​structure, which facilitates the operator to classify, collect, and clean different types of waste. To ensure that the collection box 5 maintains a stable position during use, the device also includes a limiting mechanism 20. The limiting mechanism 20 includes a limiting block 21 and an adjusting bolt 22. The limiting block 21 is fixedly connected to the lower end of the conveying mechanism 3. One end of the adjusting bolt 22 passes through the threaded hole of the limiting block 21 and contacts the outer wall of the collection box 5. The screw-in depth can be adjusted by manually rotating the adjusting bolt 22, thereby achieving precise control of the position of the collection box 5.

[0030] A dust collection assembly 17 is positioned above the conveying mechanism 3 to reduce dust generated during waste transport. The dust collection assembly 17 includes a suction duct 18 and a negative pressure fan 19. One end of the suction duct 18 is connected to the upper part of the conveying mechanism 3, and the other end is connected to the air inlet of the negative pressure fan 19. A filter screen is installed at the inlet of the suction duct 18, and the filter screen is fixed to the inner wall of the suction duct 18 with screws to prevent larger waste materials from entering the suction duct 18. The negative pressure fan 19 is fixedly installed on the outside of the device by a bracket. When it operates, it generates negative pressure, drawing dust from above the conveying mechanism 3 into the suction duct 18 and discharging it, thereby effectively reducing the impact of dust on the operating environment.

[0031] The working principle of this utility model is as follows: When the scraps and defective products generated during the rubber cutting process enter the guide trough 2 through the feed inlet of the collection box 1, the waste slides down the inclined bottom of the guide trough 2 to the starting end of the conveying mechanism 3. After the drive motor 8 starts, it drives the roller 7 to rotate through the coupling, thereby starting the conveyor belt 23. During the movement, the baffle 9 on the conveyor belt 23 gradually conveys the waste upwards, and the dividing teeth 10 of the dividing plate 4 evenly disperse the waste, avoiding accumulation or blockage during the conveying process. After being conveyed by the conveying mechanism 3, the waste falls into the interior of the collection box 5. Since the collection box 5 is equipped with a partition 15, the waste is classified and stored in different storage areas. When it is necessary to clean the waste, the operator can remove the bottom plate 16 by opening the buckle structure of the bottom plate 16, thus facilitating the cleaning and classification management of the waste. At the same time, when the negative pressure fan 19 of the dust removal component 17 is running, it draws the dust above the conveying mechanism 3 into the dust collection pipe 18 and discharges it, thereby effectively reducing the impact of dust on the operating environment.

[0032] In the above structure, the connections and coordination between the various components are rationally designed to ensure stable operation of the device and the automatic collection, conveying, and classification management of waste materials. The height of the material distribution plate 4 can be flexibly adjusted according to actual needs through the adjustment mechanism 11, thus adapting to the recycling requirements of waste materials of different sizes and shapes. Furthermore, the partition 15 design of the collection box 5 and the detachable bottom plate 16 structure further improve the efficiency of waste classification management, while the dust removal component 17 effectively reduces the impact of dust on the operating environment. The overall structure is compact and reasonable, easy to operate, and suitable for various rubber product processing scenarios.

[0033] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0034] In the rubber product processing workshop, after the cutting equipment cuts the rubber sheets, scraps and defective products are generated. These waste materials enter the guide chute 2 through the feed inlet of the collection box 1. A flexible sealing strip is installed at the edge of the feed inlet, and its material is made of wear-resistant rubber, which can effectively reduce the wear caused by the impact of the waste materials, and at the same time prevent the waste materials from getting stuck at the feed inlet. The bottom of the guide chute 2 is designed with an inclined structure, and the inclination angle is set at 15°, so that the waste materials can smoothly slide down to the starting end of the conveying mechanism 3 under the action of gravity. During this process, the side supports 6 on both sides of the collection box 1 are firmly connected to the conveying mechanism 3 by bolts to ensure the stability of the overall structure of the device.

[0035] When waste material slides onto the conveyor mechanism 3, the drive motor 8 starts and drives the roller 7 to rotate via the coupling, thereby starting the conveyor belt 23. Multiple baffles 9 are provided on the surface of the conveyor belt 23, with an 8mm gap between the height of the baffles 9 and the lower end of the distribution plate 4 to prevent waste accumulation or blockage. The conveyor belt 23 is made of anti-slip material and has evenly distributed raised structures on its surface. These raised structures increase the friction between the waste material and the conveyor belt 23, preventing the waste material from sliding during transport. Simultaneously, the distribution teeth 10 of the distribution plate 4 evenly disperse the waste material. The tips of the distribution teeth 10 are inclined towards the direction of movement of the conveyor belt 23 at an angle of 40°, ensuring that the waste material can be evenly distributed to different areas of the conveyor belt 23, thereby improving the uniformity of waste distribution.

[0036] In actual operation, if it is necessary to process waste materials of different sizes or shapes, the height of the material distribution plate 4 can be adjusted by adjusting the mechanism 11. Specifically, manually rotating the handwheel 14 causes the adjusting screw 12 to rotate, which in turn moves the material distribution plate 4 up and down along the guide rod 13 via a threaded connection until the desired height is reached. This height adjustment function allows the device to flexibly adapt to various waste recycling needs.

[0037] After being conveyed by the conveying mechanism 3, the waste falls into the collection box 5. The collection box 5 is divided into multiple storage areas by partitions 15, and each storage area has a removable bottom plate 16. When the waste accumulates to a certain level, the operator can remove the bottom plate 16 by opening the buckle structure, thus facilitating the sorting and cleaning of the waste. In addition, the adjusting bolt 22 in the limiting mechanism 20 can be manually rotated to adjust the screw-in depth, ensuring that the collection box 5 maintains a stable position during use and preventing waste from scattering due to vibration.

[0038] Throughout the waste conveying process, the dust collection assembly 17 operates continuously to reduce the impact of dust on the operating environment. A negative pressure fan 19 generates negative pressure through the suction duct 18, drawing dust from above the conveying mechanism 3 into the duct and discharging it. A filter screen is installed at the inlet of the suction duct 18, fixed to the inner wall with screws to prevent larger waste materials from entering the duct and causing blockages. This design not only effectively reduces the dust concentration in the workshop but also protects the health of the operators.

[0039] As can be seen from the above steps, the various components of this utility model, through reasonable design and coordination, achieve the functions of automatic collection, uniform dispersion, classified storage, and dust treatment of waste materials. The height adjustment function of the material distribution plate 4 and the partition design of the collection box 5 significantly improve the flexibility and efficiency of waste management, while the dust removal component 17 further optimizes the safety and comfort of the working environment. The overall structure is compact and reasonable, easy to operate, and suitable for various rubber product processing scenarios.
