[0002] Belt conveyors are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, and food for the assembly, testing, debugging, packaging, and transportation of objects. Belt conveyors have strong conveying capacity, long conveying distance, simple structure, easy maintenance, and can be easily programmed and automated, which is why they are widely used.

[0003] Currently, the commonly used protective devices for belt conveyors are mostly fixed fences or simple baffles. Fixed fences or integral baffles need to be completely disassembled before equipment maintenance or conveyor belt cleaning can be carried out, which seriously hinders daily maintenance operations. The disassembly and assembly process of integral baffles is cumbersome, and each maintenance requires multiple people to cooperate in disassembly, which increases labor costs and affects production efficiency. Therefore, a belt conveyor with a protective device is proposed. Utility Model Content

[0027] Example 1

[0028] In the current technology, the commonly used protective devices for belt conveyors are mostly fixed fences or simple baffles. Fixed fences or integral baffles need to be completely disassembled before equipment maintenance or conveyor belt cleaning can be carried out, which seriously hinders daily maintenance operations. The disassembly and assembly process of integral baffles is cumbersome, and each maintenance requires multiple people to cooperate in disassembly, which increases labor costs and affects production efficiency.

[0029] Please see Figure 1-6This utility model provides a technical solution: a belt conveyor with a protective device, including a fixed frame 1, a conveyor belt 2, a drive roller 6, and a driven roller 7. Protective components 3 are provided on both sides of the fixed frame 1. The drive roller 6 and driven roller 7 are respectively located at both ends of the conveyor belt 2 to drive its cyclic rotation. A motor 5 is mounted on one side of the fixed frame 1 via a flange. The output end of the motor 5 is coaxially fixed with the drive roller 6, and the motor 5 drives the drive roller 6 to rotate. The outer side of the drive roller 6 is provided with anti-slip textures to increase friction with the conveyor belt 2. The conveyor belt 2... Multiple support rollers 9 are evenly arranged to support the carrying section and return section of the conveyor belt. The outer side of the guide roller 8 is fitted with the surface of the stainless steel cold-rolled coil 33 with a gap of 0.5-1mm. The surface of the guide roller 8 is covered with a polyurethane wear-resistant layer. Adjustment holes are reserved on both sides of the fixing frame 1 to accommodate the adjustment of the spacing of the support rollers 9. The support rollers 9 support the conveyor belt 2. The guide rollers 8 are provided on both sides of the support rollers 9. The outer side of the guide roller 8 is in contact with the surface of the stainless steel cold-rolled coil 33. The guide rollers 8 are used in conjunction when the conveyor belt 2 moves to prevent the conveyor belt 2 from deviating.

[0030] The protective assembly 3 includes a support frame 31 and two movable plates 35. A rotating shaft 32 is movably sleeved on the outside of the support frame 31. A stainless steel cold-rolled coil 33 is wound around the outside of the rotating shaft 32. Several through slots 37 are evenly opened on both sides of the stainless steel cold-rolled coil 33. Several positioning holes 34 are evenly opened on both sides of the fixed frame 1. Several inserts 36 are evenly fixed on one side of the movable plate 35. One end of the insert 36 passes through the through slots 37 and the positioning holes 34 in sequence. A handle 38 is fixedly connected to the side of the movable plate 35 away from the inserts 36. An anti-slip sleeve is provided on the outside of the handle 38. The movable plate 35 is moved by the handle 38. The anti-slip sleeve increases the friction between the hand and the handle 38. Several threaded holes are opened on both the upper and lower parts of the movable plate 35. The movable plate 35 is fixedly connected to the outside of the fixed frame 1 by high-strength bolts, and the bolts are symmetrically distributed on both sides of the inserts 36. The movable plate 35 is fixedly connected to the outside of the fixed frame 1 by bolts, thereby fixing the unfolded stainless steel cold-rolled coil 33 to one side of the fixed frame 1.

[0031] In terms of working principle or structural principle, during use, motor 5 drives the drive roller 6 to rotate, and the conveyor belt 2 moves between the drive roller 6 and the driven roller 7. Support roller 9 provides support for the conveyor belt 2, and stop roller 8 prevents the conveyor belt 2 from deviating during movement. Under normal conditions, the stainless steel cold-rolled coil 33 is in a coiled state, such as... Figure 2 In the state shown, when protection of the belt conveyor is required, pull the stainless steel cold-rolled coil 33 to unfold it upwards along the fixed frame 1. The unfolded stainless steel cold-rolled coil 33 is then placed against the outside of the fixed frame 1. The movable plate 35 is then placed against one side of the fixed frame 1. Figure 6As shown, the insert block 36 on one side of the movable plate 35 passes through the through slot 37 and the positioning hole 34 in sequence, and then the movable plate 35 is fixedly connected to one side of the fixed frame 1 by bolts. The unfolded stainless steel cold-rolled coil 33 plays a protective role for the belt conveyor.

[0032] Example 2

[0033] Both sides of the rotating shaft 32 are provided with winding and fixing components 4. The winding and fixing components 4 include a sleeve 41, which is movably sleeved on the outside of the rotating shaft 32. The inside of the sleeve 41 is provided with a right-hand internal thread 42, and the outside of the rotating shaft 32 is provided with a right-hand external thread 43 that is adapted to it. The thread direction is consistent with the winding direction of the stainless steel cold-rolled coil 33. Rotating the sleeve 41 along the winding direction causes the external thread 43 to mesh with the internal thread 42, pushing the sleeve 41 to move axially. Each rotation moves the sleeve 41 axially by one pitch. The outside of the sleeve 41 is provided with anti-slip texture 44, which increases the friction between the sleeve 41 and the hand. The opening of the sleeve 41 is provided with a notch 45, which is a funnel-shaped design to facilitate better insertion of the wound stainless steel cold-rolled coil 33 into the sleeve 41.

[0034] Working principle or structural principle: After the unfolded stainless steel cold-rolled coil 33 is used, the moving plate 35 is removed from the fixed frame 1, and the rotating shaft 32 is rotated in the opposite direction, so that the unfolded stainless steel cold-rolled coil 33 is wound around the rotating shaft 32. Hold the sleeve 41 and rotate the sleeve 41. The internal thread 42 inside the sleeve 41 engages with the external thread 43 outside the rotating shaft 32, so that the sleeve 41 moves along the direction close to the wound stainless steel cold-rolled coil 33. The two sleeves 41 fix the two ends of the wound stainless steel cold-rolled coil 33, realizing the rapid winding of the stainless steel cold-rolled coil 33.

[0035] In summary, during use, before starting the belt conveyor, the stainless steel cold-rolled coil 33 is pulled upwards along the fixed frame 1 and unfolded. The unfolded stainless steel cold-rolled coil 33 fits against the outside of the fixed frame 1. The insert block 36 on one side of the moving plate 35 passes through the through slot 37 and the positioning hole 34 in sequence and is then fixed. The unfolded stainless steel cold-rolled coil 33 provides protection for the belt conveyor. After use, the moving plate 35 is detached from the fixed frame 1, and the rotating shaft 32 is reversed to wind the unfolded stainless steel cold-rolled coil 33 around the rotating shaft 32. The rotating sleeve 41 moves along the direction close to the wound stainless steel cold-rolled coil 33, and the two sleeves 41 fix the two ends of the wound stainless steel cold-rolled coil 33, realizing the rapid winding of the stainless steel cold-rolled coil 33. The motor 5 is a CLJSJ-CH02 manufactured by Kunshan Taiya Electromechanical Technology Co., Ltd. Since the structure and operating principle of this model are existing technologies, its structure and operating principle will not be described in detail here.
