Description

Technical Field

[0001] This utility model relates to the field of paper stacking and packaging, and in particular to a feeding device for paper stacking and packaging equipment. Background Technology

[0002] In today's paper stacking industry, paper stacking equipment plays a crucial role. It achieves efficient packing of paper stacks by wrapping the outer surface of the flat paper stacks with outer packaging paper. The paper feeding device, as a key component of this equipment, is mainly responsible for accurately conveying the paper stacks to the waiting station, preparing them for subsequent packaging processes.

[0003] However, existing paper feeding devices have some significant shortcomings. Currently, most paper feeding devices require the pusher plate to be connected to multiple power sources to complete the pushing and avoidance actions. This design not only leads to a significant increase in cost, but also results in a less smooth pushing process due to delays in the connection between multiple power sources (such as motors or cylinders), thus affecting the operating efficiency of the equipment.

[0004] To reduce the use of a power source, existing technologies employ chains for pushing. However, in practical applications, because the chain operates at high speeds for extended periods, its pushing accuracy largely depends on the chain tension. This necessitates frequent chain maintenance to ensure the required tension, increasing maintenance workload and costs. Furthermore, chain-driven systems themselves occupy a large area, complicating overall equipment layout and limiting the device's compactness and flexibility.

[0005] Furthermore, when the chain pushes the paper stack to the pallet waiting at the workstation, it needs to rotate downwards to return to its original position, resulting in a certain amount of space between the pallet and the chain. This prevents the paper stack from being fully pushed into place, affecting packaging quality. More seriously, during the chain's downward rotation, the paper stack is prone to tilting, further reducing the yield rate and causing unnecessary losses in production. Summary of the Invention

[0006] This utility model addresses the shortcomings of existing technologies by providing a feeding device for paper stacking and packaging equipment that reduces costs and ensures a high yield.

[0008] The horizontal driving cam of the present utility model can drive the pushing plate to transfer the material onto the supporting plate, and the lifting driving cam can drive the pushing plate to enter the vertical movement track and move up and down in the vertical direction, reducing the possibility of the paper stack tilting. During the process of the pushing plate pushing the material onto the supporting plate, the positioning stop cooperates to position and correct the material, improving the yield. In addition, the lifting driving cam and the horizontal driving cam are coaxially arranged, reducing the power source and lowering the cost.

The lifting drive cam 322 and the horizontal drive cam 324 are coaxially arranged, which has high synchronization and low cost. A rotary power source is provided on the frame 1. The output end of the rotary power source is connected to a rotating shaft. The lifting drive cam 322 and the horizontal drive cam 324 are arranged on the rotating shaft, and the rotating shaft drives the lifting drive cam 322 and the horizontal drive cam 324 to rotate. The lifting drive cam 322 is connected to the push plate 31 via the first linkage group 321. The lifting drive cam 322 drives the push plate 31 to achieve a vertical motion trajectory. In this embodiment, the first linkage group 321 includes a first roller follower 321a, a first lifting rod 321b, a first rocker arm 321c, and a lifting rod of the push plate 31. The first roller end of the first roller follower 321a rolls with the lifting drive cam 322. The other end of the first roller is connected to the first lifting rod 321b. The other end of the first lifting rod 321b is connected to the first rocker arm 321c. The other end of the first rocker arm 321c is connected to the lifting rod of the push plate 31. The other end of the lifting rod of the push plate 31 is connected to the lifting base 5. The connection between the first roller follower 321a, the first lifting rod 321b, the first rocker arm 321c, and the lifting rod of the push plate 31 is a movable connection, such as a hinge.

[0023] A horizontal drive cam 324, which is connected to the push plate 31 through a second link group 323. The horizontal drive cam 324 drives the push plate 31 to achieve a horizontal movement trajectory. In this embodiment, the specific structure of the second link group 323 is that the second link group 323 includes a second roller follower 323a, a second horizontal pull rod 323b, a second swing rod 323c and a paper pushing pull rod 323d.

The connection modes between the second roller follower 323a, the second horizontal pull rod 323b, the second swing rod 323c and the paper pushing pull rod 323d are movable connections, such as hinge connections. The vertical movement distance of the push plate 31 driven by the lifting drive cam 322 is a vertical movement trajectory, and the horizontal movement formed by the horizontal drive cam 324 driving the push plate 31 back and forth is a horizontal movement trajectory. The upward movement path of the push plate 31 in place → the forward movement path of the push plate 31 for pushing materials → the downward movement path of the push plate 31 for avoidance → the backward movement path of the push plate 31 for returning form a rectangular trajectory. The push plate 31 moves up and down vertically to avoid affecting the materials and ensure the posture of the materials.

[0024] A material supporting and positioning component 4, which includes a supporting plate 41 and a positioning stop 42.

The positioning stop 42 also has a vertical inner side surface 422, and the vertical inner side surface 422 is arranged on the opposite side of the opening 421. The push plate 31 pushes the materials onto the supporting plate 41 through the opening 421, and the push plate 31 cooperates with the vertical inner side surface 422 of the positioning stop 42 to correct the posture of the materials, prevent the materials from tilting, and improve the yield rate.

The material guiding cavity 423 is in a converging shape, and the material guiding cavity 423 gradually becomes larger towards the opening 421, which is convenient for materials that are skewed left and right to enter. During the movement process, the left side stop and the right side stop of the positioning stop 42 gradually correct the materials to avoid material offset during packaging and ensure the posture of the materials.

[0025] To achieve a more rational layout, the first swing arm 321c is rotatably mounted on the first swing arm spindle 6, which is fixedly mounted on the frame 1. The second swing arm 323c is rotatably mounted on the second swing arm spindle 7, and the second swing spindle is fixedly mounted on the frame 1. The first and second swing arm spindles 6 and 7 are offset vertically to save space. The vertical projection lines of the first and second swing arms 321c and 323c are parallel to avoid interference.

[0026] The working principle of this utility model is described below with reference to the accompanying drawings: The material is placed on the conveying platform 2. The lifting drive cam 322 drives the push plate 31 to move upward along the vertical movement trajectory, pass through the transfer connection channel 21 and contact the material. The horizontal drive cam 324 drives the push plate 31 to move horizontally, pushing the material through the opening 421 of the positioning stop 42 onto the push plate 31. Then the push plate 31 moves downward and returns to its horizontal position.

[0027] During the process of material entering the push plate 31, the material is corrected for its left and right deviation by the guide cavity 423. When the material contacts the front side stop, the push plane of the push plate 31 and the vertical inner side 422 cooperate to correct the material's front and back deviation, thereby improving the yield. At the same time, the position of the positioning stop 42 can position the material to ensure that the material is accurately in place.
