[0002] The widespread use of paper products in modern industrial production is driving demand for efficient and precise production equipment. With the rapid development of the logistics industry and rising environmental awareness, market demand for paper pallets, a lightweight, recyclable logistics packaging material, is growing. Paper pallets typically consist of a flat support frame with legs attached below. During the production of paper pallets, trimming is a critical step in ensuring precise dimensions and smooth edges, directly impacting product quality and transportation safety.

[0003] Existing devices for trimming paper pallets often require the pallet to be positioned and fixed before trimming, and the position of the pallet to be trimmed is manually aligned with the cutter. At the same time, the pallet is fixed with a fixing device to ensure the stability of the pallet before the paper pallet can be trimmed. There are many steps before trimming, the operation is cumbersome, and the flexibility is poor. When the direction of the pallet needs to be changed for trimming, the pallet often needs to be repositioned and fixed, and the trimming efficiency is low. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] according to Figure 1-5 As shown: The utility model provides a paper product production trimming device: it includes a cutting table 1, to which a support frame 2 is fixedly connected; a tray 7 located above the cutting table 1 is provided in the support frame 2, and a support leg 17 is fixedly connected to the bottom of the main body of the tray 7; a material storage trough 12 is provided in the cutting table 1, and a support frame 8 is rotatably connected to the material storage trough 12 through a rotating structure; a removal groove 9 connected to the material storage trough 12 is provided on one side of the cutting table 1, and a sealing plate is fixedly connected to the removal groove 9 by screws. After trimming the tray 7, waste material can directly fall into the material storage trough 12. After a period of time, the sealing plate is removed and the waste material in the material storage trough 12 can be taken out from the removal groove 9.

[0022] Two sliding frames 13 are slidably arranged in the support frame 8, and the support legs 17 are located in the sliding frames 13; a slide groove 21 is opened in the support frame 8, and an adjustment component fixedly connected to the sliding frame 13 is slidably arranged in the slide groove 21; a hydraulic cylinder 3 is provided on the support frame 2, and the working end of the hydraulic cylinder 3 is fixedly connected to the lifting plate 4, and a pressing plate 5 is connected to the bottom of the lifting plate 4 through an elastic sliding structure; the pressing plate 5 is pressed on the pallet 7, and cutters 6 are fixedly connected on both sides of the lifting plate 4, which can cut off the edge of the pallet 7 exposed from the support frame 8.

[0023] like Figure 2 、 3 As shown, the rotating structure includes a rotating motor 10 and a rotating shaft 11. The rotating motor 10 is arranged at the bottom of the cutting table 1. The rotating shaft 11 is fixedly connected to the output shaft of the rotating motor 10, and the rotating shaft 11 is fixedly connected to the support frame 8. By setting the rotating motor 10 and the rotating shaft 11, the rotation control of the support frame 8 can be facilitated.

[0024] like Figure 5As shown, the adjustment assembly comprises a sliding plate 20, which slides within a slide slot 21. A guide slot 18 is defined within the support frame 8 and communicates with the slide slot 21. The sliding plate 20 passes through the guide slot 18 and is fixedly connected to the slide frame 13. A bidirectional screw 19 is rotatably mounted within the slide slot 21. Two sliding plates 20 are provided, each threadedly connected to corresponding positions on the bidirectional screws 19. Rotation of the bidirectional screws 19 moves the two sliding plates 20 toward or away from each other, thereby adjusting the distance between the two slide frames 13 and ensuring that the spacing between the slide frames 13 corresponds to the spacing between the legs 17.

[0025] like Figure 4 As shown, the elastic sliding structure includes a fixed rod 14 and a spring 15. The fixed rod 14 is fixedly connected to the pressure plate 5, and the lifting plate 4 is slidably sleeved on the fixed rod 14; the spring 15 is located between the lifting plate 4 and the pressure plate 5, and the spring 15 is sleeved on the fixed rod 14. After cutting, under the action of the rebound force of the spring 15, the lifting plate 4 can be easily reset relative to the pressure plate 5; a limit block 16 fixedly connected to the fixed rod 14 is provided above the lifting plate 4, which can prevent the lifting plate 4 and the pressure plate 5 from separating.

[0026] Principle of the utility model

[0027] like Figure 5 As shown, before trimming the tray 7, first adjust the distance between the two sliding frames 13 according to the distance between the legs 17 below the tray 7; turn the bidirectional screw 19, and the two sliding plates 20 drive the two sliding frames 13 to move closer to or away from each other. After adjusting the distance between the two sliding frames 13, directly place the tray 7 on the support frame 8 so that the legs 17 of the tray 7 are located inside the sliding frames 13, thereby quickly completing the positioning of the tray 7. Figure 2 、 3 As shown, the hydraulic cylinder 3 is directly started, and the lifting plate 4 drives the pressure plate 5 to move downward. When the pressure plate 5 is pressed on the pallet 7, the pressure plate 5 no longer moves. Under the action of the hydraulic cylinder 3, the lifting plate 4 continues to move downward to compress the spring 15. After the compression spring 15 is compressed, it exerts pressure on the pressure plate 5, so that the pressure plate 5 exerts a fixing force on the pallet 7. At the same time, the lifting plate 4 continues to move downward to trim the two sides of the pallet 7, and the trimmed waste directly falls into the storage trough 12.

[0028] When the trimming direction needs to be changed, the hydraulic cylinder 3 is started to move the lifting plate 4 and the pressure plate 5 away from the support frame 8. At this time, when the pallet 7 is in the positioning state, the rotating motor 10 is directly started to drive the entire support frame 8 to rotate, thereby changing the direction of the pallet 7; then the hydraulic cylinder 3 is used to trim the pallet 7 again.

[0029] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
