Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a conveying device for a paper product processing production line. Background Technology

[0002] Circular conveyors are common material handling equipment widely used in manufacturing, logistics, and food processing industries. The core component of a circular conveyor is a circular track, which can be a chain, belt, roller, or other type of transmission medium. It transports materials continuously or intermittently through a closed circular path.

[0003] Patent CN112722747A discloses a combined circular conveyor system, including two turning machines and at least four vertically and horizontally extendable linear conveyors. One turning machine's two ends are respectively connected to the non-vertical extension ends of two of the vertically and horizontally extendable linear conveyors. The vertical extension ends of the two vertically and horizontally extendable linear conveyors are respectively used to connect to external equipment, and adapt to the end position of the external equipment through extension or lifting. The other turning machine's two ends are respectively connected to the non-vertical extension ends of the other two vertically and horizontally extendable linear conveyors. The vertical extension ends of the other two vertically and horizontally extendable linear conveyors are respectively used to connect to external equipment, and adapt to the end position of the external equipment through extension or lifting. The combined circular conveyor system of this invention can be used to connect one or more external devices of different specifications by combining different conveyors, making it highly adaptable. However, when this circular conveyor system is in use, because there is a circular section, the material on the conveyor belt is easily deflected by inertia when passing through the circular section and collides with the edge of the conveying device, resulting in damage to the material. Therefore, the circular conveyor system has poor protection effect on the material.

[0004] Based on the above, the present invention proposes a conveying device with protective effect for a paper product processing production line. Summary of the Invention

[0005] To overcome the shortcomings of existing circular conveyor systems, where materials on the conveyor belt are easily deflected by inertia and collide with the edges of the conveying device due to the circular section, resulting in material damage, this invention provides a protective conveyor device for paper product processing production lines.

[0006] A conveying device for a paper product processing production line includes a frame, a conveyor belt, a dual-axis motor, rollers, an outer ring expansion block, an inner ring expansion block, air cylinders, air guide pipes, connecting pipes, and guide blocks. The frame is rotatably connected to annularly distributed rollers, with pairs of conveyor belts wound between the rollers. The frame is fixedly connected to a dual-axis motor, the output end of which is fixedly connected to the rollers via a coupling. The frame is fixedly connected to an outer ring expansion block, an inner ring expansion block, and pairs of air cylinders. Air guide pipes are fixedly connected and communicate with the inner ring expansion block. Pairs of axially distributed connecting pipes are fixedly connected between the inner and outer ring expansion blocks. The output end of the dual-axis motor is fixedly connected to a pair of guide blocks, which are slidably connected to the piston rods of the air cylinders.

[0007] Furthermore, the paired conveyor belts are centrally symmetric rather than axisymmetric.

[0008] Furthermore, the two output shafts of the dual-axis motor rotate in opposite directions.

[0009] Furthermore, the guide block is elliptical.

[0010] Furthermore, it also includes a pressing mechanism, which is mounted on the frame. The pressing mechanism includes an outer ring guide frame, a limiting frame, an inner ring guide frame, a moving frame, a pressing frame, a flexible block, a servo motor, and a friction block. The outer ring guide frame is fixed to the frame, the inner ring guide frame is fixed to the frame, the limiting frame is fixed to the frame, and a ring-shaped moving frame is slidably connected between the outer ring guide frame and the inner ring guide frame. The moving frame is fixed to a pressing frame distributed along the line, the limiting frame and the pressing frame are in a pressing fit, and pairs of ring-shaped flexible blocks are fixed between the ring-shaped moving frames. A servo motor is fixed to one side of the moving frame, and a friction block is fixed to the output end of the servo motor. The friction block is in contact with the inner ring guide frame.

[0011] Furthermore, the limiting frame has an arc-shaped structure.

[0012] Furthermore, the pressure rack is composed of connecting ropes and counterweights.

[0013] Furthermore, it also includes a support mechanism, which is set on the frame. The support mechanism includes limit blocks, drive shafts and drive belts. Pairs of limit blocks are fixed to the frame. Pairs of drive shafts are rotatably connected to the frame. Drive belts are wound between the drive shafts and the rollers.

[0014] Furthermore, it also includes an unloading mechanism, which is mounted on the frame. The unloading mechanism includes a guide frame, a mounting frame, studs, rollers, a support plate frame, and a transmission wheel. The mounting frame is slidably connected to the frame and threaded with a pair of studs. The studs are pressed into the frame. The mounting frame is fixedly connected to the guide frame, which is made of rubber. The guide frame is fixedly connected to a pair of support plate frames. The support plate frames are rotatably connected to a pair of rollers. The support plate frames are rotatably connected to a pair of transmission wheels. The rollers are in contact with the transmission wheels, and the transmission wheels are in contact with the conveyor belt.

[0015] Furthermore, it also includes a cleaning mechanism, which is mounted on the frame. The cleaning mechanism includes a suction block, a guide pipe, and a vacuum cleaner. The vacuum cleaner is fixed to the frame and is connected to the guide pipe. The end of the guide pipe away from the vacuum cleaner is fixed to and connected to the suction block.

[0016] Beneficial effects:

[0017] 1. This invention, through components such as air cylinders and guide blocks, enables the outer and inner ring expansion air blocks to expand and contract intermittently, thereby intermittently squeezing the paper products and keeping them in a centered position. This prevents the paper products from shifting due to inertia when passing through the circular section and from being damaged by colliding with the frame, thus improving the protective effect of this conveying device on the paper products.

[0018] 2. This invention increases the counterweight of paper products by using components such as the pressure rack and the limiting rack, thereby increasing the friction between the paper products and the conveyor belt. This prevents the paper products from shifting due to inertia when passing through the circular section and from being damaged by colliding with the frame, thus improving the protective effect of this conveying device on paper products.

[0019] 3. This invention, through components such as limiting blocks and drive shafts, can fill the gaps and depressions at the junction of two conveyor belts and continue to transport paper products, thereby preventing damage to paper products during transportation due to getting stuck in the gaps and depressions at the junction, and improving the protective effect of this conveying device on paper products.

[0020] 4. This invention enables automatic transport and unloading of paper products through components such as guide frames and rollers, thereby eliminating the need for manual unloading, reducing the labor intensity of workers, improving the user experience, and enhancing the automation level of this conveying device.

[0021] 5. This invention, through components such as suction blocks and vacuum cleaners, can clean dust and other impurities from the surface of the conveyor belt, thereby ensuring the cleanliness of the conveyor belt and preventing paper products from being contaminated by dust and other impurities, thus improving the protective effect of this conveying device on paper products.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0037] Example 1

[0038] A conveying device for a paper product processing production line, such as Figures 1-5 As shown, the system includes a frame 1, conveyor belts 11, a dual-axis motor 12, rollers 13, an outer ring expansion block 14, an inner ring expansion block 1401, an air cylinder 15, an air guide pipe 16, a connecting pipe 17, and a guide block 18. The upper part of the frame 1 is rotatably connected to annularly distributed rollers 13, with two conveyor belts 11 wound between the annularly distributed rollers 13. A dual-axis motor 12 is fixedly connected to the middle of the frame 1, and the output end of the dual-axis motor 12 is fixedly connected to two adjacent rollers 13 via a coupling. An outer ring expansion block 14 is fixedly connected to the outer side of the upper part of the frame 1. An inner ring expansion block 1401 is fixedly connected to the inner side. Two pairs of air cylinders 15 are fixedly connected to the front and rear sides of the frame 1, which are symmetrically distributed. Each pair includes two air cylinders 15, one in front and one in back. The two air cylinders 15 in the front and rear pairs are fixedly connected to the inner ring expansion block 1401 and connected by an air guide pipe 16. Axially distributed connecting pipes 17 are fixedly connected to the front and rear sides of the inner ring expansion block 1401 and the outer ring expansion block 14. Two guide blocks 18 are fixedly connected to the output ends of the dual-axis motor 12 on both the front and rear sides. The guide blocks 18 are slidably connected to the piston rod of the adjacent air cylinder 15.

[0039] like Figures 1-4 As shown, the two conveyor belts 11 on the left and right are centrally symmetric rather than axisymmetric.

[0040] like Figures 1-5 As shown, the front and rear output shafts of the dual-axis motor 12 rotate in opposite directions.

[0041] like Figure 4 and Figure 5 As shown, the guide block 18 is elliptical.

[0042] When workers need to transport paper products via the circular conveyor, they can first place the paper products on the top right of the right conveyor belt 11, then start the dual-axis motor 12 to drive the roller 13 and the conveyor belt 11 to rotate. This allows the paper products to move clockwise along the frame 1 using the conveyor belt 11. During this process, the dual-axis motor 12 also drives the guide block 18 to rotate. The rotation of the elliptical guide block 18 causes the two adjacent left and right piston rods to move in opposite directions, thus inputting the gas from the air cylinder 15 into the inner ring expansion block 1401 through the air pipe 16. Some of the gas entering the inner ring expansion block 1401 enters the outer ring expansion block 14 through the connecting pipe 17, causing both the inner and outer ring expansion blocks 1401 to expand and compress the paper products, thus moving the paper products to the conveyor belt 1401. The conveyor belt 11 is positioned in the middle and away from the edge. As the elliptical guide block 18 continues to rotate, the adjacent left and right piston rods move towards each other and reset. The gas in the outer ring expansion block 14 and the inner ring expansion block 1401 is drawn back to the air cylinder 15 through the connecting pipe 17 and the air guide pipe 16. The inner ring expansion block 1401 and the outer ring expansion block 14 then contract and return to their original state. This cycle allows the outer ring expansion block 14 and the inner ring expansion block 1401 to expand and contract intermittently, thereby intermittently squeezing the paper product and keeping it in the center position. This prevents the paper product from shifting due to inertia and being damaged by colliding with the frame 1 when passing through the circular section. When the paper product is transported to the appropriate position by the conveyor belt 11, the worker can manually remove the paper product.

[0043] Example 2

[0044] Based on Example 1, such as Figure 6 and Figure 7 As shown, it also includes a pressing mechanism, which is set on the frame 1. The pressing mechanism includes an outer ring guide frame 2, a limiting frame 201, an inner ring guide frame 202, a moving frame 21, a pressing frame 22, a flexible block 23, a servo motor 24, and a friction block 25. The outer ring guide frame 2 is fixed to the outer side of the top of the frame 1. The inner ring guide frame 202 is fixed to the inner side of the top of the frame 1. The limiting frame 201 is fixed to the right side of the top of the frame 1. A ring-shaped moving frame 21 is slidably connected between the outer ring guide frame 2 and the inner ring guide frame 202. Three pressing frames 22 are fixed to the bottom of the moving frame 21 and are distributed along the line. The limiting frame 201 and the pressing frames 22 are pressed together. Two sets of ring-shaped flexible blocks 23 are fixed between the ring-shaped moving frames 21. A servo motor 24 is fixed to the front of one of the moving frames 21 on the rear left side. A friction block 25 is fixed to the output end of the servo motor 24. The friction block 25 is in contact with the inner ring guide frame 202.

[0045] like Figure 6 As shown, the limiting frame 201 has an arc-shaped structure.

[0046] like Figure 6 As shown, the pressure rack 22 is composed of a connecting rope and a counterweight.

[0047] When the worker starts the dual-axis motor 12, the servo motor 24 can also be started simultaneously. The servo motor 24 will drive the friction block 25 to rotate, and under the action of friction between it and the inner ring guide frame 202, it will drive the ring-shaped moving frame 21, the pressure frame 22, and the flexible block 23 to move clockwise along the outer ring guide frame 2 and the inner ring guide frame 202. The moving speed of the moving frame 21 and other components is the same as the conveyor belt 11. When the pressure frame 22 moves to contact the limiting frame 201, the connecting rope in the pressure frame 22 will be squeezed and deformed, causing the bottom counterweight to slide on the top of the limiting frame 201. At this time, Workers can place paper products directly below the limiting frame 201. When the pressing frame 22 moves to separate from the limiting frame 201, the counterweight in the pressing frame 22 will fall on top of the paper product under its own weight, thereby increasing the counterweight of the paper product and increasing the friction between the paper product and the conveyor belt 11. This prevents the paper product from shifting due to inertia and being damaged by colliding with the frame 1 when passing through the circular section. When the worker removes the paper product, the counterweight in the pressing frame 22 will move downward to reset under its own weight and straighten the corresponding connecting rope.

[0048] like Figure 8 and Figure 9 As shown, it also includes a support mechanism, which is set on the frame 1. The support mechanism includes limit blocks 3, drive shafts 31 and drive belts 32. The four limit blocks 3 are respectively fixed to the left and right sides of the front and rear sides of the frame 1. The front and rear sides of the frame 1 are rotatably connected to the drive shafts 31. The drive shafts 31 and the adjacent rollers 13 are wound with drive belts 32.

[0049] When the paper product is conveyed to the junction of the two conveyor belts 11, the limiting block 3 supports the paper product, thereby preventing the paper product from getting stuck in the gap or depression at the junction. The drive shaft 31 rotates synchronously with the adjacent roller 13 under the action of the drive belt 32, thereby continuing to convey the paper product in contact with the drive shaft 31 to the left or right. In this way, the limiting block 3 can fill the gap and depression at the junction of the two conveyor belts 11, and the drive shaft 31 can continue to transport the paper product, thereby preventing the paper product from being damaged due to getting stuck in the gap or depression at the junction during the transportation process.

[0050] like Figures 10-12As shown, it also includes an unloading mechanism, which is set on the frame 1. The unloading mechanism includes a guide frame 4, a mounting frame 41, studs 42, rollers 43, a support plate frame 44, and a transmission wheel 45. The mounting frame 41 is slidably connected to the top of the frame 1. The front and rear sides of the mounting frame 41 are threaded with studs 42, which are pressed into the frame 1. The top of the mounting frame 41 is fixedly connected to the guide frame 4, which is made of rubber. The bottom left and right sides of the guide frame 4 are fixedly connected to the support plate frame 44. The front and rear sides of the upper part of the support plate frame 44 are rotatably connected to the rollers 43, and the front and rear sides of the lower part of the support plate frame 44 are rotatably connected to the transmission wheels 45. The rollers 43 are in contact with the adjacent transmission wheels 45, and the transmission wheels 45 are in contact with the conveyor belt 11.

[0051] When a worker needs to remove a paper product from a certain position on the frame 1, they can first place the mounting bracket 41 and other components at the corresponding position on the top of the frame 1. Then, they rotate the two studs 42 clockwise, moving them towards each other while rotating, until both studs 42 contact and press against the frame 1, thus fixing the mounting bracket 41 to the frame 1. At this time, the drive wheel 45 will contact the conveyor belt 11. When the conveyor belt 11 transports the paper product to the guide frame 4, the drive wheel 45 will be subjected to friction between itself and the conveyor belt 11. The reverse rotation causes the roller 43 in contact with it to rotate in the forward direction, which in turn causes the paper products in contact with the roller 43 to continue moving along the guide frame 4 and eventually fall into the external collection device. This enables automatic transportation and unloading of paper products, eliminating the need for manual unloading, reducing the labor intensity of workers, improving the user experience, and increasing the automation level of the conveying device. When not needed, the two studs 42 are rotated in the reverse direction to reset the two studs 42 and remove the mounting frame 41 and other components from the frame 1.

[0052] like Figure 13 As shown, it also includes a cleaning mechanism, which is set on the frame 1. The cleaning mechanism includes a suction block 5, a guide pipe 51 and a vacuum cleaner 52. The vacuum cleaner 52 is fixed to the rear right side of the frame 1. The top of the vacuum cleaner 52 is fixed to and connected to the guide pipe 51. The end of the guide pipe 51 away from the vacuum cleaner 52 is fixed to and connected to the suction block 5.

[0053] During transportation, the vacuum cleaner 52 can also be turned on. The vacuum cleaner 52 will suck up dust and other impurities from the surface of the conveyor belt 11 through the guide pipe 51 and the suction block 5, thereby cleaning the dust and other impurities from the surface of the conveyor belt 11, ensuring the cleanliness of the conveyor belt 11 and preventing paper products from being contaminated by dust and other impurities. The vacuum cleaner 52 can be turned off when not needed.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
