Abstract

This utility model discloses a feeding device for a folding machine, comprising a base frame and a side plate. A first feeding roller, a second feeding roller, a third feeding roller, and a fourth feeding roller are sequentially arranged on the side of the side plate. These four feeding rollers are rotatably connected to the side plate. An adjustment assembly is provided on the side of the side plate. The adjustment assembly includes a base fixed to the base frame, an electric cylinder mounted on the base, and a connecting rod connected to the electric cylinder. A fastening block is fixed to the side of the side plate. A transmission roller passes through the side plate and extends to the outside of the side plate. By setting the adjustment assembly, the up-and-down movement of the transmission roller can be precisely controlled. The electric cylinder drives the connecting rod, thereby adjusting the transmission roller and the blocking plate, thus adjusting the distance between the blocking plate and the pressure plate, and thus conveying papers of different thicknesses.

Description

Technical Field

[0001] This utility model relates to the field of feeding devices, specifically a feeding device for a folding machine. Background Technology

[0002] The feeding device of a folding machine is a crucial component, primarily responsible for separating and conveying paper, ensuring its accurate and stable delivery to the folding section. In practice, the feeding device works in conjunction with the transmission and folding systems. The transmission system transmits power to the folding system via motors, belts, and bearings. The folding system includes components such as the paper feeder, folding blades, and folding plates, which work together to complete the paper folding operation. When the operator places the paper to be folded into the feeder, the motor starts, driving the belt to rotate and feeding the paper between the folding blades and folding plates. The folding blades cut and fold the paper according to preset folding methods and specifications, while the folding plates position and support the paper, ensuring accuracy and stability. Furthermore, the feeding device may include auxiliary components such as pressure rollers, positioning plates, and blocking plates to further improve the stability and accuracy of paper transport. For example, pressure rollers help the paper adhere more closely to the feed rollers, while positioning and blocking plates prevent the paper from shifting or slipping during transport.

[0003] Because the paper needs to travel a certain distance before entering the folding process, its own weight and the changes in roller tension can cause uneven movement and varying tension during the process. This can lead to the paper tilting to one side or shifting, resulting in uneven folded edges. Therefore, the existing solution is to add a certain number of conveyor rollers, a fixed structure, and baffles to the feeding device. The conveyor rollers ensure smooth paper transport, and the fixed structure and baffles maintain a certain distance. After smooth transport, the paper passes through the gap between the fixed structure and the baffles again, ensuring that the paper does not shift. However, this method still has drawbacks. Different conditions require different paper thicknesses, resulting in significant variations in the thickness of the folded paper. Due to the complexity of the paper folding process, adjusting the paper thickness uniformity is difficult. The distance between the fixed structure and the baffles in the above method is difficult to adjust, usually requiring manual adjustment or using other tools to move the baffles. This cannot meet the needs of conveying paper of different thicknesses and is very cumbersome. Utility Model Content

A first feeding roller, a second feeding roller, a third feeding roller, and a fourth feeding roller are sequentially arranged on the side of the side plate. The first feeding roller, the second feeding roller, the third feeding roller, and the fourth feeding roller are rotatably connected to the side plate. An adjustment assembly is provided on the side of the side plate. The adjustment assembly includes a base fixedly mounted on the base frame, an electric cylinder mounted on the base, and a connecting rod connected to the electric cylinder. A fastening block is fixedly mounted on the side of the side plate. A transmission roller is provided on the side of the side plate, passing through the side plate and extending to the outside of the side plate. The transmission roller is rotatably connected to the fastening block. The connecting rod is fixedly connected to the transmission roller.

[0009] Furthermore, the second feeding roller is located below the first feeding roller, the third feeding roller is located below the second feeding roller, and the fourth feeding roller is located below the third feeding roller.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-3 As shown, a feeding device for a folding machine includes a base frame 3 and a side plate 1. A first feeding roller 12, a second feeding roller 13, a third feeding roller 14, and a fourth feeding roller 15 are sequentially arranged on the side of the side plate 1. The first feeding roller 12, the second feeding roller 13, the third feeding roller 14, and the fourth feeding roller 15 are rotatably connected to the side plate 1. An adjustment assembly 2 is provided on the side of the side plate 1. The adjustment assembly 2 includes a base 4 fixedly mounted on the base frame 3, an electric cylinder 5 mounted on the base 4, and a connecting rod 6 connected to the electric cylinder 5. A fastening block 7 is fixedly mounted on the side of the side plate 1. A transmission roller 8 is provided on the side of the side plate 1, passing through the side plate 1 and extending to the outside of the side plate 1. The transmission roller 8 is rotatably connected to the fastening block 7. The connecting rod 6 is fixedly connected to the transmission roller 8. A positioning plate 9 is fixedly mounted on the transmission roller 8. A blocking plate 10 is fixedly mounted on the positioning plate 9.

[0018] A roller plate 11 is fixedly installed on the side of the side plate 1. The roller plate 11 is inclined downward. The first feeding roller 12, the second feeding roller 13, the third feeding roller 14, and the fourth feeding roller 15 all have the same diameter. The first feeding roller 12, the second feeding roller 13, the third feeding roller 14, and the fourth feeding roller 15 pass through the side plate 1. The second feeding roller 13 is located below the first feeding roller 12, the third feeding roller 14 is located below the second feeding roller 13, and the fourth feeding roller 15 is located below the third feeding roller 14. This top-to-bottom arrangement... This method allows the paper to gradually decrease in height during the feeding process, which better meets the feeding requirements of the folding machine. By setting multiple feeding rollers, precise control of paper transmission can be achieved, ensuring stable and efficient paper transmission. The design of the roller pressure plate 11 allows the paper to fit more closely to the feeding rollers, further improving the stability of paper transmission. The diameters of the first feeding roller 12, the second feeding roller 13, the third feeding roller 14, and the fourth feeding roller 15 are all the same. This design makes the force on the paper more uniform during transmission, avoiding deformation or damage to the paper during transmission and ensuring the quality of the paper.

[0019] In this embodiment, the feeding device of a folding machine can precisely control the up-and-down movement of the transmission roller 8 by setting the adjustment component 2. The electric cylinder 5 drives the connecting rod 6 to move, thereby adjusting the transmission roller 8 and the blocking plate 10, thereby adjusting the distance between the blocking plate 10 and the roller pressure plate 11, so as to convey papers of different thicknesses to meet different folding requirements.
