Description

Technical Field

[0001] This utility model relates to the technical field of thin sheet material conveying equipment, specifically an anti-jumping conveying device. Background Technology

[0002] Thin, sheet-like products, such as printed materials, packaging bags, and paper, typically require transfer via conveyor systems during production. In practice, to facilitate transportation, assembly, and flexible matching, these systems usually consist of multiple sequentially arranged transfer units of uniform height. This arrangement creates gaps between adjacent units, facilitating installation and preventing interference. Furthermore, the small weight of these products means that after the head of the material detaches from the previous transfer unit, it tilts downwards due to lack of support. Then, due to inertia, it tilts upwards again upon contact with the next transfer unit. This causes the material to bounce during transfer, affecting the stability of the process. Figure 1 As shown, it may even slip out of the transmission channel, affecting the continuity of the production line. In the existing technology, the linear speed of the transmission unit is usually increased to reduce the degree of vibration, but this requires high quality of the transmission device, causes great wear, and is not conducive to reducing costs. Utility Model Content

[0003] This utility model discloses an anti-jumping conveying device, which solves the technical problem in the prior art that thin, sheet-like materials are prone to jittering during transport, affecting the stability of the transfer. It features a reasonable structure, stable material transfer, and good economic benefits. The technical solution adopted is as follows: An anti-jump transmission device includes a first transmission unit and a second transmission unit arranged sequentially along the transmission direction. The transmission platform formed by the first transmission unit includes a first end close to the second transmission unit, and the transmission platform formed by the second transmission unit includes a second end close to the first transmission unit, with the first end located above the second end.

[0004] Based on the above technical solution, the transmission platforms formed by the first transmission unit and the second transmission unit are both horizontally arranged and have a height difference.

[0005] Based on the above technical solution, the transmission platform formed by the first transmission unit and / or the second transmission unit has a downward tilt angle along the transmission direction.

[0006] Based on the above technical solution, the downward tilt angle is no greater than 20°.

[0007] Based on the above technical solution, the first transmission unit and / or the second transmission unit adopts a belt conveyor. The belt conveyor includes two drive rollers, at least one tension roller, and multiple conveyor belts arranged in parallel and sleeved outside the two drive rollers and the tension roller. The tension roller is used to tension the conveyor belts. At least one of the drive rollers is arranged with adjustable front and rear positions to adjust the horizontal distance between the first end and the second end.

[0008] Based on the above technical solution, the first transmission unit and / or the second transmission unit adopts a roller conveying device, which includes multiple rollers arranged in parallel.

[0009] Based on the above technical solution, the vertical height difference between the first end and the second end is no more than 30mm.

[0010] Based on the above technical solution, the horizontal distance between the first end and the second end is designed to be less than half the size of the material along the conveying direction on the conveying device.

[0011] Based on the above technical solution, a third transmission unit is also included. The first transmission unit, the second transmission unit and the third transmission unit are arranged sequentially along the transmission direction. The transmission platform formed by the second transmission unit includes a fourth end close to the third transmission unit. The transmission platform formed by the third transmission unit includes a third end close to the second transmission unit, and the fourth end is located above the third end.

[0012] Based on the above technical solution, the transmission platform formed by the third transmission unit is horizontally set or has a downward tilt angle along the transmission direction.

[0013] Beneficial effects This utility model has a reasonable structure. The first and second transmission units are arranged sequentially along the transmission direction, with the first end of the first transmission unit positioned above the second end of the second transmission unit. This stepped arrangement of the first and second transmission units, with a height difference, allows the material head to smoothly and stably fall onto the second end of the second transmission unit after exiting from the first end. This reduces material jolting during transmission, helps maintain stability, and lowers the failure rate. Furthermore, the ingenious design of this utility model, employing a stepped arrangement of the first and second transmission units, also helps reduce manufacturing or modification costs, resulting in good economic benefits.

[0014] In this invention, the first, second, and third transmission units are flexibly arranged, and the resulting transmission platform can be horizontally positioned or have a downward tilt angle. When the transmission platform formed by one of the transmission units has a downward tilt angle, when the head of the material product exits from that transmission unit, it has a downward tilt angle and, under its own weight, has a force component along the transmission direction. This allows the material product to transition to the next transmission unit more quickly, reducing material jolting. The design is ingenious. Furthermore, a third transmission unit may be included, and the number of third transmission units can be one or more to easily adapt to different production needs. Attached Figure Description

[0021] Example 1 An anti-jumping transmission device includes a first transmission unit 1 and a second transmission unit 2 arranged sequentially along the transmission direction. In this embodiment, the first transmission unit 1 and the second transmission unit 2 are spaced apart and both use belt conveyors, which include multiple conveyor belts extending in the transmission direction and arranged side by side. In other embodiments of this invention, the first transmission unit 1 and the second transmission unit 2 use roller conveyors, which include multiple rollers arranged side by side. Both belt conveyors and roller conveyors are existing technologies and will not be described in detail here.

[0022] The transmission platform formed by the first transmission unit 1 includes a first end 11 near the second transmission unit 2, and the transmission platform formed by the second transmission unit 2 includes a second end 21 near the first transmission unit 1, with the first end 11 positioned above the second end 21. Figure 2 and 3 As shown, the transmission platforms formed by the first transmission unit 1 and the second transmission unit 2 are both horizontally arranged with a height difference, forming a stepped structure. This allows the material product head to smoothly and stably fall onto the second end 21 of the second transmission unit 2 after it detaches from the first end 11 of the first transmission unit 1. This reduces the degree of bouncing during material transfer, helps maintain the stability of the transfer process, and lowers the failure rate. The vertical height difference between the first end 11 and the second end 21 is no more than 30mm, and the horizontal distance between the first end 11 and the second end 21 is designed to be less than half the size of the material along the transmission direction on the transmission device. This further reduces the degree of anti-jumping during the material transmission process and further improves the stability of the transfer process.

[0023] Example 2 The difference between Example 2 and Example 1 is that, as Figure 4 and 5 As shown, it also includes a third transmission unit 3. The first transmission unit 1, the second transmission unit 2 and the third transmission unit 3 are arranged in sequence along the transmission direction. The transmission platform formed by the second transmission unit 2 also includes a fourth end 22 near the third transmission unit 3. The transmission platform formed by the third transmission unit 3 includes a third end 31 near the second transmission unit 2, and the fourth end 22 is located above the third end 31. Thus, the first transmission unit 1, the second transmission unit 2 and the third transmission unit 3 have a height difference, forming a stepped shape.

[0024] like Figure 4 and 5 As shown, the transmission platform formed by the first transmission unit 1, the second transmission unit 2, and the third transmission unit 3 extends horizontally.

[0025] Example 3 The difference between Example 3 and Example 2 is that, as Figure 6 As shown, the first transmission unit 1, the second transmission unit 2, and the third transmission unit 3 all employ belt conveyors. The first transmission unit 1 includes two drive rollers 100, at least one tension roller 200, and multiple conveyor belts arranged side-by-side and fitted over the drive rollers 100 and tension roller 200. The conveyor belts have a flat cross-section. The tension roller 200 is used to tension the conveyor belts. The tension roller 200 is adjustable in height (front-to-back or up-and-down), which is existing technology and will not be described further. Furthermore, the drive roller 100 in the first transmission unit 1, near the second transmission unit 2, is adjustable in position. This allows adjustment of the horizontal distance between the first end 11 and the second end 21, providing flexibility and adaptability to material specifications. The structure enabling the adjustable position of the drive roller 100 is existing technology and will not be described further here.

[0026] Example 4 The difference between Example 4 and Example 2 is that, as Figure 7 As shown, the transmission platform formed by the second transmission unit 2 has a downward tilt angle along the transmission direction, and the downward tilt angle is no more than 20°. Thus, when the head of the material product comes out of the second transmission unit 2, it has a downward tilt angle and has a component force along the transmission direction under its own weight. This allows the material product to transition to the third transmission unit 3 at a faster speed, reducing the degree of material jumping. The design is ingenious.

[0027] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
