Description

Technical Field

[0001] This utility model relates to the field of cutting technology, and in particular to an automatic cutting device for scrap materials after the production of rubber conveyor belts. Background Technology

[0002] As a core component in the field of material conveying, rubber conveyor belts are widely used in industrial scenarios such as mining, ports, metallurgy, and chemical industries. Their production quality directly affects the efficiency and safety of subsequent material conveying. In the production process of rubber conveyor belts, after vulcanization, molding and other processes, the edges of the conveyor belt blanks often form scraps that exceed the preset size. These scraps not only affect the appearance regularity of the conveyor belt, but also cause edge wear and cracking due to uneven stress during subsequent laying and operation, thereby shortening the service life of the conveyor belt.

[0003] To meet the needs of large-scale production, rubber conveyor belt manufacturers generally use automatic cutting devices to replace traditional manual cutting. These automatic cutting devices typically consist of a frame, feeding mechanism, positioning and identification mechanism, cutting execution mechanism, and waste collection mechanism.

[0004] Currently, most automatic cutting devices for rubber conveyor belt scraps use a traditional bolt-fastened structure for the blade holder. Specifically, the blade is connected and fixed to the blade holder body by multiple through bolts, usually 3-6 bolts, which are evenly distributed on the edge area of ​​the blade. When changing the blade, the operator must first use a special wrench to loosen and remove the fixing bolts one by one. After the old blade is removed, the new blade is placed in the bolt holes on the blade holder, and then the bolts are tightened one by one to ensure that the blade and the blade holder fit tightly and there is no relative shaking.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Example 1: Reference Figure 1-4 A basic embodiment of conventional thin conveyor belt cutting (limiting clip 12 + ordinary cutting blade 14) This device is suitable for cutting scraps from ordinary rubber conveyor belts. The upper end of the cutting blade 14 slides into the cutting blade groove 13 of the fixed block 11. The limiting clip 12 is engaged in the first limiting clip groove 15 of the cutting blade under the action of the return spring 16. The fixed clip 19 locks the position of the push block 17. During cutting, the hydraulic telescopic rod 8 drives the fixed block to move the cutting blade downward. The limiting clip ensures that the cutting blade does not deviate. When disassembling, pull out the fixed clip and push the push block to make the limiting block 18 disengage from the second limiting block groove 21. Then the limiting clip can be pulled out to replace the cutting blade. The operation is simple and suitable for the regular cutting needs of small and medium-sized conveyor belt production.

[0024] Example 2: Reference Figure 5 Example of a sturdy conveyor belt cutting method (trapezoidal limiting block 23 + thickened cutting blade) For heavy-duty rubber conveyor belt scraps, the installation stability of the cutting blade needs to be enhanced. The limiting clip is replaced with a trapezoidal limiting block 23, whose trapezoidal surface and the second limiting block groove 22 form a wedge-shaped self-locking mechanism to prevent loosening under force during cutting. The cutting blade 14 is thickened, and the blade is made of high-strength alloy material. When cutting thick materials, the trapezoidal limiting block firmly holds the cutting blade, and the thickened blade body resists the cutting impact without deformation. The push block 17 is enlarged to improve the ease of operation and ensure that the thick conveyor belt scraps are cut flat and do not slip, meeting the processing requirements of industrial-grade heavy-duty conveyor belts.

[0025] Furthermore, when using this device, the drive mechanism of the feeding mechanism 2 drives the unloading roller to rotate, conveying the rubber conveyor belt to be cut forward. When the conveyor belt passes under the tension roller 3, the sliding seat of the tension roller 3 is driven to move up and down by rotating the adjusting threaded rod 10, adjusting the contact pressure between the tension roller 3 and the conveyor belt, so that the conveyor belt is kept flat and taut (to avoid skewing of the cut due to looseness during cutting). The cut conveyor belt body continues to be conveyed backward, and the drive mechanism of the winding mechanism 4 drives the take-up roller to rotate to complete the winding. Then, according to the width requirement of the rubber conveyor belt scrap, the motor 5 is started, and its output end drives the bidirectional threaded rod 9 in the support frame 6 to rotate. Due to the two sliding seats 7 and the bidirectional threaded rod The threaded rod 9, restricted from rotation by the inner wall of the support frame 6, drives the two sliding seats 7 to slide horizontally in opposite directions along the support frame 6 when it rotates. This causes the lower limit mounting components to move synchronously, adjusting the distance between the two cutting blades 14 and precisely aligning them with the scrap material to be cut. Then, when the conveyor belt reaches the cutting position and remains taut, the hydraulic telescopic rod 8 starts and extends downward, causing the fixing block 11 and the cutting blades 14 to move downward synchronously. The lower blade of the cutting blade 14 contacts the scrap material on the conveyor belt, and the cutting is completed under the driving force of the hydraulic telescopic rod 8. After cutting, the hydraulic telescopic rod 8 retracts, causing the cutting blades 14 to return to their original position, ready for the next cutting cycle. Then, slide the upper end of the cutter 14 into the cutter groove 13 of the fixing block 11 until the first limiting block groove 15 is aligned with the second limiting block groove 22. At this time, under the elastic force of the return spring 16, the limiting piece 12 slides along the second limiting block groove 22 toward the cutter 14, and its end is inserted into the first limiting block groove 15. At the same time, the limiting block 18 slides synchronously along the first limiting block groove 20 and the second limiting block groove 21 to ensure the stability of the movement trajectory of the limiting piece 12. Finally, the fixing block 19 slides into the space between the push block 17 and the inner wall of the groove to lock the position of the push block 17 and prevent the limiting piece 12 from loosening, thus completing the fixing of the cutter 14. When it is necessary to replace or maintain the cutter 14, manually move it inward. The side-pressing push block 17 drives the limiting block 18 to compress the return spring 16, and at the same time pushes the fixing block 19 out of the locked position. The limiting card 12 slides away from the cutting blade 14 with the push block 17, and its end is pulled out from the first limiting card groove 15, releasing the constraint on the cutting blade 14. At this time, the cutting blade 14 can be pulled down along the cutting blade slide groove 13 to complete the disassembly. When the limiting card 12 is replaced by the trapezoidal limiting card 23, its trapezoidal structure has a larger contact area with the first limiting card groove 15 and stronger friction, which is suitable for cutting thicker or harder rubber conveyor belt scraps. It can improve the locking stability of the cutting blade 14 and prevent the cutting blade from deviating due to excessive force during cutting.

[0026] By using the mechanical linkage structure between the limiting clip 12 and the push block 17 in the limiting installation assembly, the blade changing process is simplified to four steps: "press the push block - pull out the blade - insert the new blade - release the push block". No tools such as wrenches are needed throughout the process. Specifically, when disassembling, pressing the push block 17 will cause the limiting clip 12 to disengage from the first limiting clip groove 15, thus releasing the lock on the cutting blade 14. When installing, simply slide the cutting blade 14 into the cutting blade slide groove 13 of the fixing block 11, and the limiting clip 12 will automatically engage with the first limiting clip groove 15 under the elastic force of the return spring 16, forming a double lock with the fixing block 19, which can reduce downtime losses caused by blade changing.
