DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0037] Example 1

[0038] A conveying device for a paper product processing production line, such as Figure 1-Figure 5 As shown, it includes a frame 1, a conveyor belt 11, a double-axis motor 12, a roller 13, an outer ring expansion gas block 14, an inner ring expansion gas 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 with an annularly distributed roller 13, and two left and right conveyor belts 11 are wound between the annularly distributed rollers 13. The middle part of the frame 1 is fixedly connected with a double-axis motor 12, and the output end of the double-axis motor 12 is fixedly connected to the two adjacent rollers 13 through a coupling. The outer ring expansion gas block 14 is fixedly connected to the outer side of the upper part of the frame 1. The upper part of the frame 1 An inner ring expansion air block 1401 is fixedly connected to the inside, and two pairs of air cylinders 15 symmetrically distributed on the left and right are fixedly connected to the front and rear sides of the frame 1, wherein each pair includes two front and rear air cylinders 15, and an air guide pipe 16 is fixedly connected and connected to the two front and rear pairs of air cylinders 15 and the inner ring expansion air block 1401, and axially distributed connecting pipes 17 are fixedly connected to the front and rear sides between the inner ring expansion air block 1401 and the outer ring expansion air block 14, and two guide blocks 18 are fixedly connected to the output ends of the front and rear sides of the dual-axis motor 12, and the guide blocks 18 are slidably connected to the piston rods of the adjacent air cylinders 15.

[0039] like Figure 1-Figure 4 As shown, the left and right conveyor belts 11 are centrally symmetrically distributed rather than axially symmetrically distributed.

[0040] like Figure 1-Figure 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 oval.

[0042] When workers need to transport paper products through the ring conveying device, they can first place the paper products on the right top of the right conveyor belt 11, and then start the dual-axis motor 12 to drive the roller 13 and the conveyor belt 11 to rotate, so that the paper products are moved clockwise along the frame 1 with the help of the conveyor belt 11. During this period, the dual-axis motor 12 will also drive the guide block 18 to rotate, and the rotation of the elliptical guide block 18 will first cause the adjacent left and right piston rods to move backwards, so that the gas in the air cylinder 15 is input into the inner ring expansion gas block 1401 through the air guide pipe 16, and part of the gas entering the inner ring expansion gas block 1401 will enter the outer ring expansion gas block 14 through the connecting pipe 17, so that the inner ring expansion gas block 1401 and the outer ring expansion gas block 14 are expanded and squeezed, so that the paper products move to the conveyor The middle position of the conveyor belt 11 is away from the edge, and the elliptical guide block 18 continues to rotate, which will cause the adjacent left and right piston rods to move toward each other and reset, and the gas in the outer ring expansion air block 14 and the inner ring expansion air block 1401 is drawn back to the air cylinder 15 through the connecting pipe 17 and the air guide pipe 16, and the inner ring expansion air block 1401 and the outer ring expansion air block 14 immediately shrink and return to their original state. This cycle can make the outer ring expansion air block 14 and the inner ring expansion air block 1401 expand and shrink intermittently, thereby intermittently squeezing the paper product and keeping it in the center position, thereby preventing the paper product from being offset due to inertia when passing through the circular section and being damaged due to collision with the frame 1. 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] On the basis of Example 1, Figure 6 and Figure 7 As shown, it also includes a pressing mechanism, which is arranged on the frame 1. The pressing mechanism includes an outer ring guide frame 2, a limit frame 201, an inner ring guide frame 202, a mobile 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, and the limit frame 201 is fixed to the right side of the top of the frame 1. A circularly distributed mobile frame 21 is slidably connected between the outer ring guide frame 2 and the inner ring guide frame 202. Three pressing frames 22 distributed along the line are fixed to the bottom of the mobile frame 21. The limit frame 201 and the pressing frame 22 are extruded and matched. Two groups of inner and outer circularly distributed flexible blocks 23 are fixed between the circularly distributed mobile frames 21. A servo motor 24 is fixed to the front of a mobile frame 21 on the left rear side. The output end of the servo motor 24 is fixed to the friction block 25, and the friction block 25 is in contact with the inner ring guide frame 202.

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

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

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

[0048] like Figure 8 and Fig. 9 As shown, a supporting mechanism is also included, which is arranged on the frame 1. The supporting mechanism includes a limit block 3, a transmission shaft 31 and a transmission belt 32. The four limit blocks 3 are respectively fixed to the left and right parts of the front and rear sides of the frame 1. The front and rear sides of the frame 1 are rotatably connected with the transmission shaft 31, and a transmission belt 32 is wound between the transmission shaft 31 and the adjacent roller 13.

[0049] When the paper products are conveyed to the junction of the two conveyor belts 11, the limit block 3 will support the paper products to prevent the paper products from getting stuck in the gaps and depressions at the junction, and the transmission shaft 31 will rotate synchronously with the adjacent roller 13 under the action of the transmission belt 32, so that the paper products in contact with the transmission shaft 31 continue to be conveyed to the left or right, so that the gaps and depressions at the junction of the two conveyor belts 11 can be filled with the help of the limit block 3, and the paper products can continue to be transported with the help of the transmission shaft 31, thereby preventing the paper products from being damaged due to getting stuck in the gaps and depressions at the junction during transportation.

[0050] like Figure 10-12As shown, a discharge mechanism is also included, which is arranged on the frame 1, and 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, and the front and rear sides of the mounting frame 41 are both threadedly connected with studs 42, and the studs 42 are extruded and matched with the frame 1. The top of the mounting frame 41 is fixedly connected with a guide frame 4, wherein the guide frame 4 is made of rubber, and the left and right sides of the bottom of the guide frame 4 are fixedly connected with support plate frames 44, the front and rear sides of the upper part of the support plate frame 44 are rotatably connected with rollers 43, and the front and rear sides of the lower part of the support plate frame 44 are rotatably connected with 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 take out a paper product from a certain position of the rack 1, he can first place the mounting frame 41 and other components at the corresponding position on the top of the rack 1, and then rotate the two studs 42 in the forward direction, and move the two studs 42 toward each other while rotating, until the two studs 42 contact and squeeze the rack 1, thereby fixing the mounting frame 41 on the rack 1, and at this time the transmission wheel 45 will contact the conveyor belt 11, and when the conveyor belt 11 transports the paper product to the guide rack 4, the transmission wheel 45 will be under the action of the friction between the conveyor belt 11 The two studs 42 rotate in the opposite direction, thereby driving the roller 43 in contact with it to rotate forward, so that the paper products in contact with the roller 43 continue to move along the guide frame 4 and finally fall into the external collection device, thereby realizing the automatic transportation and unloading of paper products, and no longer needing manual unloading, reducing the labor intensity of workers, improving the user experience and the degree of automation of the conveying device. When not needed, the two studs 42 are rotated in the opposite direction to move the two studs 42 back to reset and remove the mounting frame 41 and other components from the frame 1.

[0052] like Fig.13 As shown, a cleaning mechanism is also included, which is arranged on the frame 1. The cleaning mechanism includes a suction block 5, a guide pipe 51 and a dust collector 52. The dust collector 52 is fixedly connected to the right rear side of the frame 1. The top of the dust collector 52 is fixedly connected to and connected with the guide pipe 51. The end of the guide pipe 51 away from the dust collector 52 is fixedly connected to and connected with the suction block 5.

[0053] The vacuum cleaner 52 can also be started during transportation. The vacuum cleaner 52 will suck in dust and other impurities on the surface of the conveyor belt 11 through the guide pipe 51 and the suction block 5, so as to clean the dust and other impurities on the surface of the conveyor belt 11, thereby 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 is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
