Description

Technical Field

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

[0002] After corrugated cardboard is formed, it needs to be transported from one processing point to another. Conveyor belts or conveyor rollers are commonly used to transport the cardboard. In order to reduce the deviation of the cardboard during production, a guiding mechanism is set up to guide the cardboard during transport, so that the cardboard is transported stably to the next processing point.

[0003] Chinese Patent CN219525665U discloses a conveying device for paper product processing. Specifically, it discloses that the outer walls of conveyor rollers A and B are both provided with annular grooves, the inner wall of the guide conveyor belt is provided with rubber strips that contact the annular grooves, and a pressing roller is provided at the top of the conveyor belt. The pressing roller is mounted on a mounting plate, and a lifting component for adjusting the height of the mounting plate is installed on the frame. The patent fixes conveyor rollers A and B by fixing them with the rubber strips through the annular grooves. However, with prolonged use, wear of the rubber strips can cause the conveyor belt to deviate. Furthermore, the pressing roller and the mounting plate are rigid structures, and when the paperboard thickness is uneven or there are local bulges, the pressure cannot be adaptively adjusted, which may crush the corrugated structure or obstruct the conveying. Therefore, there is an urgent need for a conveying device for paper product processing that can prevent the conveyor belt from deviating and automatically adapt and adjust the pressure of the pressing roller. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a conveying device for paper product processing that can prevent the conveyor belt from running off-track and automatically adapt to and adjust the pressure of the pressing roller.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a conveying device for paper product processing, comprising:

[0006] Base;

[0007] The conveyor belt is connected to the base along the X-axis.

[0008] A guiding mechanism is positioned above the conveyor belt. The guiding mechanism includes two sets of guiding devices symmetrically arranged around the center of the conveyor belt surface. Each guiding device includes a cylinder, a fixed block, a side connecting block, a first conveyor roller, a second conveyor roller, a third conveyor roller, a fourth conveyor roller, a conveyor belt, and a motor. The side connecting block is connected to one end of the fixed block. Several rotatable first conveyor rollers are connected to the bottom of the fixed block, each with a first external thread. The second conveyor roller is rotatably connected to the bottom of the side connecting block, with a second external thread at its bottom. The third conveyor roller has a first internal thread matching the first external thread, and the fourth conveyor roller has a second internal thread matching the second external thread. Annular blocks are provided on the outer walls of the first, second, third, and fourth conveyor rollers. An annular groove matching the annular block is provided on the conveyor belt. The cylinder body is connected to a base, with the cylinder body axis in the Y direction. The side wall of the fixed block is connected to the piston rod of the cylinder. The motor is connected to the first conveyor rollers via a transmission connection.

[0009] The pressure regulating device is connected to the X-axis side of the guide mechanism. The pressure regulating device includes a top plate, a movable plate, an elastic mechanism, a pressure regulating frame, and a pressing roller. The top plate is located above the conveyor belt, and both ends of the top plate are connected to the base through side plates. Both ends of the pressure regulating frame are slidably connected to the side plates. The pressing roller is rotatably connected inside the pressure regulating frame, and the axis of rotation of the pressing roller is in the Y-axis. The movable plate is located between the pressure regulating frame and the top plate, and the movable plate is movably connected to the top plate in the vertical direction. The elastic mechanism is located between the lower part of the movable plate and the upper part of the pressure regulating frame.

[0010] A drive unit is used to drive the moving plate to move.

[0011] Furthermore, the outer wall of the annular block is provided with a wear-resistant layer.

[0012] Furthermore, the drive unit includes three electric telescopic rods, one at each end and one in the middle of the top plate.

[0013] Furthermore, the elastic mechanism includes a limiting post, a spring, and a limiting sleeve. The limiting post is connected to the lower part of the moving plate, and the limiting sleeve is connected to the upper part of the pressure regulating frame. The limiting post and the limiting sleeve are interactively connected, and the spring is coaxially connected to the limiting post. The spring is located between the moving plate and the limiting sleeve.

[0014] Furthermore, there are two elastic mechanisms, which are arranged symmetrically about the center of the conveyor belt surface.

[0015] Furthermore, mounting blocks are connected to the side walls of the fixing block and the side connecting block, and a pressure roller is rotatably mounted on the mounting block, with the side wall of the pressure roller in contact with the outer surface of the conveyor belt.

[0016] The beneficial effects of this invention are as follows: Compared with the prior art, the rolling resistance of the annular block within the annular groove is lower, reducing motor load and energy consumption. Simultaneously, the rolling contact avoids direct scraping between the metal and the conveyor belt material, significantly extending the service life of the conveyor roller and the conveyor belt. Furthermore, the annular block's embedding into the conveyor belt's annular groove is more effective at preventing belt slippage than rubber strips relying on friction for positioning. The elastic mechanism ensures the pressing roller always maintains flexible pressure on the cardboard, allowing for adaptive floating when thickness changes. The cardboard passes between the conveyor belt and the pressing roller, effectively suppressing warping and preventing damage. Attached Figure Description

[0034] The pressure regulating device 4 is connected to the X-direction side of the guide mechanism 3. The pressure regulating device 4 includes a top plate 41, a movable plate 43, an elastic mechanism 44, a pressure regulating frame 45, and a pressing roller 46. The top plate 41 is located above the conveyor belt 2. Both ends of the top plate 41 are connected to the base 1 through side plates 42. Both ends of the pressure regulating frame 45 are slidably connected to the side plates 42. The pressing roller 46 is rotatably connected inside the pressure regulating frame 45. The axis of rotation of the pressing roller 46 is in the Y direction. The movable plate 43 is located between the pressure regulating frame 45 and the top plate 41. The movable plate 43 is movably connected to the top plate 41 in the vertical direction. The elastic mechanism 44 is located between the lower part of the movable plate 43 and the upper part of the pressure regulating frame 45.

[0035] Drive device 6 is used to drive the moving plate 43 to move.

[0036] In the above embodiments, the first conveyor roller 314 and the second conveyor roller 315 are installed on the transmission belt, so that the annular blocks 5 of the first conveyor roller 314 and the second conveyor roller 315 are matched with the limiting groove. Then, the annular block 5 of the third conveyor roller 316 is matched with the limiting groove, and the first internal thread 3161 of the third conveyor roller 316 is matched with the first external thread 3141, thereby assembling the first conveyor roller 314 and the third conveyor roller 316.

Compared to existing technologies, the rolling resistance of the annular block 5 within the annular groove 3181 is lower, reducing the load on the motor 319 and lowering energy consumption. Simultaneously, the rolling contact avoids direct scratching between the metal and the conveyor belt 318 material, significantly extending the service life of the conveyor rollers and the conveyor belt 318. Furthermore, the annular block 5's embedding into the annular groove 3181 of the conveyor belt 318 provides better protection against belt slippage than rubber strips relying on friction. The elastic mechanism 44 ensures that the pressing roller 46 always maintains flexible pressure on the cardboard, allowing for adaptive floating when thickness changes. The cardboard passes between the conveyor belt 2 and the pressing roller 46, effectively suppressing warping and preventing damage.

[0037] As an optional implementation, the outer wall of the annular block 5 is provided with a wear-resistant layer 51.

[0038] In the above embodiments, the wear-resistant layer 51 is made of polytetrafluoroethylene, which further reduces friction with the transmission belt.

[0039] As an optional implementation, the drive device 6 includes three electric telescopic rods 61, with one electric telescopic rod 61 installed at each end and the middle of the top plate 41.

[0040] In the above embodiments, an electric telescopic rod 61 is provided at each of the two ends and the middle of the top plate 41, which can further enhance the stability of the moving plate 43.

[0041] As an optional implementation, the elastic mechanism 44 includes a limiting post 441, a spring 443, and a limiting sleeve 442. The limiting post 441 is connected to the lower part of the moving plate 43, and the limiting sleeve 442 is connected to the upper part of the pressure regulating frame 45. The limiting post 441 and the limiting sleeve 442 are interactively connected. The spring 443 is coaxially connected to the limiting post 441 and is located between the moving plate 43 and the limiting sleeve 442.

[0042] In the above embodiments, when encountering cardboard of different thicknesses, the spring 443 is compressed, and the limiting post 441 slides into the limiting sleeve 442, thereby allowing for adaptive floating.

[0043] As an optional implementation, there are two elastic mechanisms 44, which are arranged symmetrically about the center of the conveyor belt 2.

[0044] In the above embodiments, the pressure adjustment frame 45 is further adapted to the stability of cardboard of different thicknesses.
