Description

Technical Field

[0001] This utility model relates to the field of edge-cutting device technology, and in particular to a paper pallet edge-cutting device. Background Technology

[0002] Currently, most companies store finished products in warehouses. Placing finished products directly on the ground can cause them to become damp, potentially leading to product spoilage, especially in southern regions where the rainy season makes products highly susceptible to moisture. Common moisture-proofing methods include using metal frames, wooden frames, or foam. Foam is used due to its low cost, but its effectiveness in preventing moisture absorption is limited by its material properties. Wooden and metal frames are sturdy and resistant to moisture, making them better methods, but they are more expensive. Paper pallets are commonly used in product handling and transportation, serving to support and cushion products. Paper pallet corner protectors are used in paper pallet transportation. These corner protectors are inexpensive, lightweight, sturdy, and environmentally friendly. They are made from kraft paper and yarn tubes, shaped and pressed using a complete corner protector machine. Both ends are smooth and flat, without obvious burrs, and perpendicular to each other. They can replace wood and are 100% recyclable, making them an ideal new type of green packaging material.

[0003] During the paper pallet processing, an edge-cutting device is used to trim its edges and corners. The edge-cutting device mainly includes a control mechanism, a drive mechanism, and a cutting mechanism.

[0004] In the prior art, such as the paper pallet corner cutting device disclosed in Chinese announcement number CN210414703U, there is a support frame, a control mechanism, a drive mechanism, a feeding mechanism, a cutting mechanism, and a cutting stop mechanism. The control mechanism is installed on the support frame, the drive mechanism is installed inside the support frame, and the feeding mechanism is installed on the support frame. The feeding mechanism includes a sliding groove, a feeding rotary motor, a drive shaft, and a sliding groove rotating component. The sliding groove rotating component is provided on one side of the feeding rotary motor, and the drive shaft connects the feeding rotary motor and the sliding groove rotating component. This utility model belongs to the field of corner cutting technology, specifically providing a cutting device with high safety and protective function. The cutting device also has a certain measurement function, and the operator can freely adjust the corner cutting length according to the length of the paper pallet. This paper pallet corner cutting device is more efficient and has better performance.

[0005] The above-mentioned technology has achieved the effect of allowing multiple people to use it simultaneously, but there are still some shortcomings, specifically:

[0006] Traditional paper pallet edge trimming relies on simple mechanical pressing or manual cutting, lacking a precise positioning and force application system. Relying solely on experience to judge the blade position can easily lead to cutting deviations. Especially for irregularly shaped or large-sized pallets, it is difficult to ensure neat edges. The manual adjustment of blade pressure is affected by the operator's force, which can easily lead to local over-pressure tearing or under-pressure failure to cut, resulting in a high scrap rate and making it difficult to meet the dual requirements of precision and efficiency in modern production.

A hydraulic pump, combined with a sliding hydraulic rod and sliding plate structure, allows for rapid and stable positioning and pressure application of the cutter via hydraulic power, reducing the need for manual intervention. The sliding connection design between the placement plate and the base, combined with a groove guide, facilitates precise alignment of the paper pallet to be processed. Furthermore, the cooperation between the convex plate and the cutting groove effectively constrains paper displacement, ensuring a smooth cutting edge. Simultaneously, the sliding cooperation between the mounting block and the mounting groove enhances the equipment's adaptability, achieving a highly efficient and stable automated edge-cutting process, significantly improving product quality consistency, and thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a paper pallet trimming device, comprising a base, a support column fixedly installed at the bottom end of the base, a support plate fixedly installed on the back of the base, a hydraulic pump provided at the top end of the support plate, a hydraulic rod installed at the output end of the hydraulic pump, a sliding plate installed at the bottom end of the hydraulic rod, a cutter provided at the bottom end of the sliding plate, a placement plate provided at the top end of the base, and a protruding plate fixedly installed at the top end of the placement plate.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, the placement groove, groove, placement plate, protruding plate, cutting groove, pinching groove, mounting rod, fixing groove, protrusion, mounting block, mounting groove, threaded groove, threaded rod, handle, and tool groove improve the accuracy and efficiency of paper pallet edge cutting. The hydraulic pump, in conjunction with the sliding hydraulic rod and sliding plate structure, allows the cutter position to be quickly positioned and stably pressurized by hydraulic power, reducing the need for manual intervention. The sliding connection design between the placement plate and the base, combined with the groove guide, facilitates the precise alignment of the paper pallet to be processed. Furthermore, the cooperation between the protruding plate and the cutting groove can effectively constrain paper displacement and ensure a flat cutting edge. At the same time, the sliding cooperation between the mounting block and the mounting groove enhances the adaptability of the equipment, realizing an efficient and stable automated edge cutting process and significantly improving product quality consistency.

[0017] 2. In this utility model, the sliding groove, sliding rod, stop block, pressure plate, fixing block, spring, and anti-slip pad optimize the stability and adaptability of the cutting process.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: As Figures 1-4As shown, this utility model provides a technical solution: a paper pallet trimming device, including a base 1, a support column 2 fixedly installed at the bottom end of the base 1, a support plate 3 fixedly installed on the back of the base 1, a hydraulic pump 6 installed at the top end of the support plate 3, a hydraulic rod 8 installed at the output end of the hydraulic pump 6, a sliding plate 9 installed at the bottom end of the hydraulic rod 8, a cutter 12 installed at the bottom end of the sliding plate 9, a placement plate 15 installed at the top end of the base 1, a protruding plate 16 fixedly installed at the top end of the placement plate 15, the support columns 2 are evenly distributed at the four corners of the bottom end of the base 1, the hydraulic pump 6 is fixed to the top end of the support plate 3 through a storage groove 4, the hydraulic pump 6 is fixed inside the storage groove 4 through a fixing plate 5 and a mounting plate 7, the hydraulic rod 8 is slidably connected to the support plate 3, a fixing rod 10 is fixedly installed at the bottom end of the sliding plate 9, a connecting plate 11 is fixedly installed at the bottom end of the fixing rod 10, and the cutter 12 is connected to the fixing rod through the connecting plate 11. 10 is installed at the bottom of the sliding plate 9, and the sliding plate 9 is slidably connected to the support plate 3. The top of the base 1 is provided with a placement groove 13, and the side of the placement groove 13 is provided with a groove 14. The placement plate 15 is slidably connected to the base 1 through the placement groove 13. The side of the placement plate 15 is provided with a pinching groove 18, and the top of the placement plate 15 is provided with a cutting groove 17. The bottom of the hydraulic rod 8 is fixedly installed with an installation rod 19. The top of the sliding plate 9 is fixedly installed with a protrusion 21, and the top of the protrusion 21 is installed with an installation block 22. The installation block 22 is slidably connected to the installation rod 19 through the installation groove 23. The installation block 22 is provided with a threaded rod 25 inside. The threaded rod 25 is rotatably connected to the installation block 22 through the threaded groove 24. The threaded rod 25 is rotatably connected to the installation rod 19 through the fixing groove 20. The surface of the threaded rod 25 is fixedly installed with a handle 26, and the surface of the handle 26 is provided with a tool groove 27.

[0027] In this embodiment, significant improvements have been achieved. The use of a hydraulic pump 6 to drive the sliding plate 9 and the support plate 3 in a double sliding track design makes the movement trajectory of the cutter 12 more stable and the force more even, effectively improving the cutting accuracy. The addition of a rotatable and adjustable threaded rod 25 and a throttle 26 assembly can precisely control the stroke of the sliding plate 9 to adapt to the processing needs of materials of different thicknesses. The sliding positioning structure between the placement plate 15 and the base 1, combined with the groove 14 and pinch groove 18 design, ensures the stability of the workpiece and facilitates loading and unloading. The support columns 2 distributed at the four corners and the reinforced support plate 3 form a rigid frame, greatly enhancing the stability of the equipment operation. The modular design of the storage slot 4 and the fixing plate 5 simplifies the installation and maintenance process of the hydraulic pump 6. The overall structure is compact and reliable, and the convenience of operation and production safety are improved simultaneously.

[0028] Example 2: As Figure 1 , Figures 3-5As shown, a sliding groove 28 is provided at the top of the sliding plate 9, and a sliding rod 29 is provided inside the sliding groove 28. A stop block 30 is fixedly installed at the top of the sliding rod 29, and a pressure plate 31 is fixedly installed at the bottom of the sliding rod 29. A fixing block 32 is fixedly installed inside the pressure plate 31, and a spring 33 is fixedly installed at the top of the pressure plate 31. An anti-slip pad 34 is fixedly installed at the bottom of the pressure plate 31. The sliding groove 28 is evenly distributed at the four corners of the top of the sliding plate 9. The sliding rod 29 is slidably connected to the sliding plate 9 through the sliding groove 28, the stop block 30 is slidably connected to the sliding plate 9, and the spring 33 is slidably connected to the sliding rod 29.

[0029] In this embodiment, the practical performance of the equipment is improved. The sliding grooves 28 with evenly distributed corners and the sliding rods 29 are used to form a multi-point support system, which effectively suppresses the swaying phenomenon when the sliding plate 9 moves, and greatly improves the stability of the cutting process. The integrated spring 33-pressure plate 31 adaptive mechanism uses the elastic buffering characteristics of the spring 33 to achieve dynamic pressure compensation, which can not only ensure effective holding of the workpiece, but also avoid mechanical damage caused by rigid overload. The anti-slip pad 34 set at the bottom of the pressure plate 31 enhances the friction between it and the workpiece. With the design of the pinch groove 18, it ensures the stable positioning of workpieces of different shapes. The limiting cooperation structure between the stop block 30 and the sliding plate 9 not only restricts the sliding range to ensure safe stroke, but also facilitates quick reset. The overall structure is an optimized solution that combines high reliability and operational flexibility, which significantly improves the processing accuracy and equipment applicability compared with the prior art.

[0030] The working principle of this embodiment is as follows: In use, first place the base 1 in the desired position, allowing the support column 2 to firmly support it. When cutting is required, first lift the placement plate 15 through the pinch groove 18 and install it on the top of the base 1 through the placement groove 13. Then, place the paper tray on the top of the convex plate 16. Next, start the hydraulic pump 6 inside the storage groove 4, causing the hydraulic rod 8 to drive the sliding plate 9 downwards. At this time, the sliding plate 9 slides downwards together with the pressure plate 31 of the fixing block 32 via the sliding rod 29. When the pressure plate 31 contacts the paper tray, the anti-slip pad 34 firmly fixes it to the top of the convex plate 16. Then, the sliding rod 29 slides upwards at the bottom of the sliding plate 9 through the sliding groove 28, and the stop block 30 disengages from the top of the sliding plate 9, causing the spring 33 to slide and contract on the surface of the sliding rod 29, thus completing the fixing of the paper tray. At this time, the sliding plate 9 can then drive the cutter 12 downwards together via the fixing rod 10 and the connecting plate 11. The cutter 12 slides into the interior of the placement plate 15 through the cutting groove 17 and completely cuts the paper tray. When the cutter 12 needs maintenance after long-term use, first use the tool slot 27 to turn the handle 26 so that the threaded rod 25 rotates backward inside the mounting block 22 through the threaded groove 24. When the threaded rod 25 is completely turned out of the interior of the mounting block 22 through the threaded groove 24 and out of the interior of the mounting rod 19 through the fixing groove 20, then pinch the sliding plate 9 and press it down so that the protrusion 21 drives the mounting block 22 to slide down together. At this time, the mounting block 22 slides down on the surface of the mounting rod 19 through the mounting groove 23 to remove the sliding plate 9 from the bottom of the hydraulic rod 8 for maintenance of the cutter 12. Then, remove the hydraulic pump 6 from the interior of the support plate 3 through the mounting plate 7 and the fixing plate 5. Finally, pinch the placement plate 15 through the groove 14 and the pinching groove 18 and pull it upward so that the placement plate 15 slides out of the interior of the base 1 through the placement groove 13 for maintenance.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
