Description

Technical Field

[0001] This utility model relates to the technical field of cardboard cutting equipment, specifically to a cardboard cutting device that prevents detachment. Background Technology

[0002] Cardboard is generally used for product packaging or as a separator. During the production of cardboard, it needs to be cut to the appropriate size, which requires the use of cutting equipment.

[0003] Chinese Utility Model Publication No. CN222135088U discloses a cardboard cutting device to prevent it from falling off, including a cutting machine and a conveyor installed on one side of the cutting machine. Two protective components are symmetrically arranged on both sides of the conveyor. The protective components include a fixed box fixed to the side of the conveyor. A protective plate is provided on the side of the fixed box away from the conveyor. Two guide rods are fixed to the outer wall of the protective plate. The guide rods penetrate the surface of the fixed box and extend into the fixed box.

[0004] This device, through the cooperation of a protective plate and pressure rollers, effectively prevents cardboard from falling off. However, the multiple pressure rollers require individual adjustment, all achieved by rotating the handles and screw threads. When adjusting the handles, it's difficult for operators to ensure that all handles rotate the same number of turns, allowing the pressure rollers to rise or fall the same distance synchronously. This can easily lead to uneven movement of the rollers, resulting in varying pressure on the cardboard and causing positional shifts during cardboard movement. Consequently, the anti-fall-off effect is not very good. Furthermore, after prolonged use, the spring tension weakens, requiring disassembly of the pressure rollers. This necessitates unscrewing the handles from the screw threads, which involves numerous turns of the threads and is time-consuming, thus limiting its practicality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cardboard cutting device that prevents detachment, which improves practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cardboard cutting device to prevent detachment, comprising a cutting machine and a conveyor installed on one side of the cutting machine. Two protective components are symmetrically arranged on both sides of the conveyor. Each protective component includes a fixed box fixed to the side of the conveyor. A protective plate is provided on the side of the fixed box away from the conveyor. A top plate is provided on the top of the protective plate. A threaded hole is opened in the middle of the top plate, and a screw is threadedly installed in the threaded hole. A lifting plate is rotatably installed on the lower part of the screw. Multiple slots are arranged in an array on the lifting plate, and each slot is fitted with a locking component. The lifting plate is used to drive the multiple locking components to move synchronously. A sliding groove is provided in the middle of each locking component, and the lower part of the sliding groove penetrates the lower part of the locking component to form a slot. A pressing component is slidably installed in the sliding groove for pressing the cardboard.

[0007] Furthermore, fixed rods are fixedly installed on both sides of the lifting plate, and guide holes are opened at the corresponding positions of the top plate and the fixed rods, through which the fixed rods pass.

[0008] Furthermore, a limit block is fixedly provided at the upper end of the fixing rod.

[0009] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​plate snapping into a snap-fit ​​slot, a fixing tube fixedly disposed at the bottom of the snap-fit ​​plate, and a sliding groove disposed on the fixing tube.

[0010] Furthermore, the clamping assembly includes a slide rod that slides within a groove, a bracket fixedly mounted on the lower part of the slide rod, and a clamping wheel rotatably mounted on the middle part of the bracket.

[0011] Preferably, a spring is fitted around the outside of the slide rod.

[0012] Preferably, the inner surface of the protective plate is equipped with a number of horizontal and vertical rollers.

[0013] Compared with the prior art, this utility model provides a cardboard cutting device that prevents detachment, which has the following beneficial effects: This anti-drop cardboard cutting device, by rotating the screw, drives the lifting plate to move, which in turn moves multiple pressure rollers up and down by the same distance. This ensures that the multiple pressure rollers provide the same pressure to the cardboard, preventing the cardboard from shifting under uneven pressure and thus improving the anti-drop effect. Secondly, the snap-fit ​​method of the cardboard and slot is faster to disassemble than the threaded connection method, thus improving its practicality. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] In the prior art, a cardboard cutting device for preventing detachment includes a cutting machine 1 and a conveyor 2 installed on one side of the cutting machine 1. The cardboard is placed on the conveyor 2 for transportation. Two protective components are symmetrically arranged on both sides of the conveyor 2. The protective components include a fixed box fixed to the side of the conveyor 2. A protective plate 3 is provided on the side of the fixed box away from the conveyor 2. Several horizontal rollers 16 and vertical rollers 17 are installed on the inner surface of the protective plate 3. This is the prior art and will not be described in detail here.

[0018] Please see Figure 1-4 This utility model discloses a cardboard cutting device to prevent detachment. A top plate 4 is fixedly installed on the top of a protective plate 3. A threaded hole is formed in the middle of the top plate 4, allowing for adjustable installation of a screw 5 via a threaded connection. A lifting plate 6 is rotatably installed on the lower part of the screw 5 via a shaft, bearing, or bushing. This ensures that the lifting plate 6 can smoothly rise and fall when the screw 5 rotates, while preventing the lifting plate 6 from rotating synchronously with the screw 5. Multiple slots 7 are evenly spaced on the lifting plate 6. Each slot 7 precisely matches and engages with a snap-fit ​​component, achieving linkage between multiple snap-fit ​​components and the lifting plate 6, ensuring synchronous displacement of all snap-fit ​​components when the lifting plate 6 moves. Each snap-fit ​​component has a groove 8 in the middle. The lower part of the groove 8 penetrates the lower part of the snap-fit ​​component to form a slot. A pressing component is slidably installed within the groove 8, moving up and down along the groove 8 to press and fix the cardboard.

[0019] Fixed rods 9 are fixedly installed on both sides of the lifting plate 6. Guide holes are opened on the top plate 4 at positions corresponding to the two fixed rods 9. The fixed rods 9 can pass up and down along the guide holes, serving as guides and limits. A limit block is fixedly installed at the upper end of the fixed rod 9 to limit the downward stroke of the fixed rod 9 and prevent the lifting plate 6 from moving too low and causing the components to collide.

[0020] The locking plate 10 of the locking assembly precisely engages with the locking groove 7 of the lifting plate 6, ensuring a stable connection. A fixing tube 11 is fixedly installed at the bottom of the locking plate 10, and a sliding groove 8 is opened on the fixing tube 11, which is adapted to the size of the sliding rod 12. The sliding rod 12 of the pressing assembly can slide smoothly in the sliding groove 8. The middle of the bracket 13 fixed at its lower part is rotatably mounted with a pressing wheel 14 via a rotating shaft or bearing. The pressing wheel 14 presses against the upper part of the cardboard. A spring 15 is sleeved on the outside of the sliding rod 12. The upper and lower ends of the spring 15 are respectively set on the bracket 13 and the fixing tube 11. The spring 15 can generate elastic deformation as the sliding rod 12 slides, providing a continuous and adjustable pressing force for the pressing wheel 14.

[0021] In summary, this anti-drop cardboard cutting device, when in use, involves holding the top handle of the screw 5 with both hands and rotating it clockwise, causing the lifting plate 6 to descend smoothly under the guidance of the fixed rod 9; rotating it counterclockwise causes it to rise. Adjustments are made according to the cardboard thickness to ensure that the pressure roller 14 adheres to the cardboard surface without damaging it. During adjustment, all locking components move synchronously with the lifting plate 6, eliminating the need for individual adjustment of the single roller height. A single cardboard sample is placed at the feed end of the conveyor 2, and the cardboard is pushed under the pressure roller 14. The neatly stacked cardboard is then placed at the feed end of the conveyor 2. The conveyor 2 is then turned on, and the cardboard, guided by the horizontal roller 16 and vertical roller 17 inside the protective plate 3, smoothly enters under the pressure roller 14. The pressure roller 14, under the elastic force of the spring 15, continuously presses down on the cardboard, rotating synchronously with the conveyor 2's conveying rhythm to prevent the cardboard from shifting or falling off during transport or cutting. When spring 15 needs to be replaced, the support pulls the clamping plate 10 out of the slot 7, and the pressure wheel 14 and other devices can be taken to the maintenance position to replace spring 15.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
