Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing technology, and in particular to a corrugated cardboard die-cutting mechanism. Background Technology

[0002] Die-cutting is a crucial step in the processing of corrugated cardboard, aiming to cut the cardboard into specific shapes and sizes according to design requirements. However, existing corrugated cardboard die-cutting mechanisms have some obvious shortcomings in practical applications.

[0003] Feeding the cardboard is the first step in the entire corrugated cardboard die-cutting mechanism. The feeding mechanism can continuously transport the cardboard to the die-cutting structure. The existing feeding mechanism is not well designed. When transporting corrugated cardboard, the common method is to achieve feeding through the friction between the roller and the cardboard. However, cardboard is usually stacked. The weight generated by a large number of cardboard stacks will cause the bottom cardboard to be unable to be fed smoothly, thus affecting the efficiency of cardboard die-cutting. Therefore, this application proposes a corrugated cardboard die-cutting mechanism. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a corrugated cardboard die-cutting mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a corrugated cardboard die-cutting mechanism, including a processing table, a transport trough at the top left end, a conveyor belt installed in the transport trough, and a first motor connected to the conveyor belt shaft installed at the left end of the front side of the processing table.

[0006] The die-cutting section is installed in the middle of the top of the processing table and above the conveyor belt;

[0007] The protective cover is installed on the right side of the top of the processing table, and the right side and top of the protective cover are both open. The inner walls of the protective cover are provided with second plate grooves on both sides.

[0008] The pressure-reducing adjustment assembly is provided in two sets, which are respectively installed in the second plate grooves on both sides of the inner wall of the protective cover;

[0009] The bottom of the left end of the baffle and protective cover is provided with a feeding port, and the top of the feeding port is provided with a first plate groove. The baffle can be installed in the first plate groove in a liftable manner.

[0010] The first feeding mechanism has an inner groove inside the right end of the processing table, and the top of the first feeding mechanism is installed in the inner groove, extending to the upper surface of the right end of the processing table.

[0011] The second feeding mechanism is installed on top of the processing table and located between the conveyor belt and the protective cover.

[0012] Optionally, the first feeding mechanism includes rotating rods, rubber rollers, a third motor, and a transmission assembly. Multiple rotating rods are installed at equal intervals in the inner groove. Multiple rubber rollers are installed at equal intervals on each rotating rod, and the rubber rollers connected to the multiple rotating rods are arranged in a staggered pattern. The top of the inner groove has openings equal in number and aligned with the rubber rollers. The top of each rubber roller extends out of a corresponding opening. The third motor is installed on the rear side of the processing table. One end of one of the rotating rods extends to the rear side of the processing table and is fixedly connected to the output end of the third motor. The ends of the multiple rotating rods furthest from the third motor extend to the front side of the processing table. The transmission assembly is installed between the front ends of the multiple rotating rods.

[0013] Optionally, the horizontal height of multiple rotating rods gradually increases from left to right, and the horizontal height of the top of multiple rubber rollers gradually increases from left to right, with multiple anti-slip strips installed at equal angles on the arc surface of each rubber roller.

[0014] Optionally, the transmission assembly includes sprockets and chains, with the number of sprockets being the same as the number of rotating rods, and each sprocket being mounted at the front end of the corresponding rotating rod, and the chain being tensioned and sleeved between the multiple sprockets.

[0015] Optionally, the pressure-reducing adjustment assembly includes an adjustment plate, a clamping plate, and a second hydraulic rod. The adjustment plate is installed in the second plate groove, and a third plate groove is formed on the inner side of the adjustment plate. The clamping plate is installed in the third plate groove. The second hydraulic rod is installed on the outside of both sides of the protective cover, and the telescopic end of the second hydraulic rod passes through the protective cover and is fixedly connected to the center of the outer side of the adjustment plate. The top and bottom of the third plate groove and the clamping plate are both set as inclined surfaces with the same inclination. Ball grooves are formed at both ends of the inclined surface at the bottom of the clamping plate. Rotatable balls that roll in contact with the bottom of the third plate groove are provided in both ball grooves. The clamping plate has multiple slots with the same inclination as the inclined surface evenly formed on the side of the third plate groove. Positioning plugs with the same number as the slots and interlocking with the slots are fixedly installed in the third plate groove.

[0016] Optionally, the positioning plug includes a positioning rod and a spring. The positioning rod is fixedly connected to the inner side of the third plate groove. The positioning rod is set in an inclined shape, and the inclination of the positioning rod is the same as the inclination of the inclined surface. One end of the positioning rod is movably inserted into the corresponding slot. The spring is sleeved on the positioning rod, and both ends of the spring are fixedly connected to the third plate groove and the clamping plate, respectively.

[0017] Optionally, the second feeding mechanism includes a support frame, a feeding roller, and a second motor. A roller groove is provided on the top of the processing table between the conveyor belt and the protective cover. A rotatable rotating roller is installed in the roller groove, with its top extending out of the roller groove. The support frame is installed directly above the rotating roller, and the feeding roller is installed inside the support frame. The second motor is installed on one side of the support frame, and its output end passes through the support frame and is fixedly connected to one end of the feeding roller. Support plates are fixedly installed on both sides of the processing table, directly below the vertical parts on both sides of the support frame. Third hydraulic rods are fixedly installed at the bottom of both support plates. The telescopic ends of the two third hydraulic rods pass through the support plates and are respectively fixedly connected to the bottom ends of the vertical parts on both sides of the support frame.

[0018] Optionally, a vertical slot communicating with the first plate groove is provided at the middle position of the left side of the protective cover, a connecting block passing through the slot is fixedly installed at the center of the top left side of the baffle, and a first hydraulic rod is fixedly installed on the left side of the protective cover and above the slot, with the telescopic end of the first hydraulic rod fixedly connected to the top of the connecting block.

[0019] The beneficial effects of this utility model are:

[0020] By adjusting the distance between the two adjusting plates, it is easy to correct the position of cardboard of different sizes. As the two adjusting plates gradually approach each other, the clamps on the side of the adjusting plates will first contact the two sides of the cardboard and be squeezed into the third plate groove on the side of the adjusting plate. The clamps will move up the slope of the third plate groove, thereby lifting the cardboard held between the two clamps, thus reducing the weight borne by the cardboard at the bottom. Then, in conjunction with the rubber rollers in the first feeding mechanism, the cardboard directly below can be conveyed.

[0021] In the first feeding mechanism, the rubber rollers on multiple rotating rods are arranged in an alternating pattern, and the horizontal height of the rotating rods gradually increases from left to right. In conjunction with the anti-slip strips on the top of the rubber rollers, the friction between the rubber rollers and the cardboard can be increased. Furthermore, the cardboard is placed at an angle on top of several connecting rollers, with the bottom end of the cardboard close to the discharge port. Therefore, the third motor drives multiple rotating rods to rotate simultaneously, thereby enabling more stable conveying of the bottommost cardboard. Attached Figure Description

[0038] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0039] Please see Figures 1-9This utility model provides a technical solution: a corrugated cardboard die-cutting mechanism, including a processing table 11. A transport trough is provided at the left end of the top of the processing table 11, and a conveyor belt 13 is installed in the transport trough. A first motor 14 connected to the rotating shaft of the conveyor belt 13 is installed at the left end of the front side of the processing table 11. A die-cutting section 12 is installed at the middle position of the top of the processing table 11, above the conveyor belt 13. The core function of the die-cutting section 12 is to achieve cardboard forming through die cutting and a pressure system. A protective cover 21 is installed at the right end of the top of the processing table 11, and the right side and top of the protective cover 21 are both open. Second plate grooves 25 are provided on both sides of the inner wall of the protective cover 21. All are equipped with adjustable pressure-reducing components. A feeding port is opened at the bottom of the left end of the protective cover 21, and a first plate groove 22 is opened at the top of the feeding port. A liftable baffle 23 is installed in the first plate groove 22. An inner groove 16 is opened inside the right end of the processing table 11. A first feeding mechanism extending to the upper surface of the right end of the processing table 11 is installed in the inner groove 16. A second feeding mechanism 4 is installed at the top of the processing table 11 and at the position between the conveyor belt 13 and the protective cover 21. Through the protective cover 21, the first feeding mechanism and the second feeding mechanism 4, the feeding steps of corrugated cardboard can be realized. With the help of the adjusting plates 31 and clamping plates 33 on both sides of the inner wall of the protective cover 21, the bottom cardboard can be smoothly transported, ensuring a smooth and orderly production process.

[0040] like Figure 2 and Figure 8 As shown, the first feeding mechanism includes rotating rods 51, rubber rollers 52, a third motor 53, and a transmission assembly 54. Multiple rotating rods 51 are equidistantly installed in the inner groove 16. Multiple rubber rollers 52 are equidistantly installed on each rotating rod 51, and the connected rubber rollers 52 on the multiple rotating rods 51 are staggered. The top of the inner groove 16 has openings equal in number and aligned with the positions of the rubber rollers 52. The top of each rubber roller 52 extends out of a corresponding opening. The third motor 53 is installed on the rear side of the processing table 11. One end of one rotating rod 51 extends to the rear side of the processing table 11 and is fixedly connected to the output end of the third motor 53. The ends of the multiple rotating rods 51 away from the third motor 53 extend to the front side of the processing table 11. The transmission assembly 54 is installed between the front ends of the multiple rotating rods 51. The third motor 53 drives the multiple rotating rods 51 to rotate synchronously through the transmission assembly 54, ensuring consistent operation of the rubber rollers 52, stabilizing the cardboard feeding, and reducing deviation and slippage.

[0041] like Figure 1 and Figure 8As shown, the horizontal height of multiple rotating rods 51 gradually increases from left to right, and the horizontal height of the top of multiple rubber rollers 52 gradually increases from left to right. Multiple anti-slip strips are installed at equal angles on the arc surface of each rubber roller 52. The rubber rollers 52 with stepped height distribution can keep the conveyed cardboard in an inclined state. With the anti-slip strips on the surface of the rubber rollers 52, the feeding efficiency can be improved.

[0042] like Figure 1 and Figure 8 As shown, the transmission assembly 54 includes sprockets and chains. The number of sprockets is the same as the number of rotating rods 51, and each sprocket is installed at the front end of the corresponding rotating rod 51. The chain is tensioned and sleeved between multiple sprockets. The transmission method of sprockets and chains can reliably transmit power to each rotating rod 51, ensuring the normal operation of the first feeding mechanism.

[0043] like Figure 5 , Figure 6 and Figure 7 As shown, the pressure-reducing adjustment assembly includes an adjusting plate 31, a clamping plate 33, and a second hydraulic rod 34. The adjusting plate 31 is installed in the second plate groove 25. A third plate groove 32 is formed on the inner side of the adjusting plate 31. The clamping plate 33 is installed in the third plate groove 32. The second hydraulic rod 34 is installed on the outside of both sides of the protective cover 21, and the telescopic end of the second hydraulic rod 34 passes through the protective cover 21 and is fixedly connected to the center of the outer side of the adjusting plate 31. The top and bottom of the third plate groove 32 and the clamping plate 33 are both set as inclined surfaces with the same inclination. Ball grooves are formed at both ends of the bottom inclined surface of the clamping plate 33. Each of the two ball grooves is provided with a rotatable ball 37 that rolls in contact with the bottom of the third plate groove 32. The clamping plate 33 is located on the side of the third plate groove 32 with evenly spaced... Multiple slots 36 with the same inclination as the inclined plane are provided. Positioning plugs 35, the same number as the slots 36, are fixedly installed in the third plate groove 32 and are interlocked with the slots 36. By adjusting the distance between the two adjusting plates 31, the clamping plates 33 on the side of the adjusting plate 31 first contact the two sides of the cardboard. The two clamping plates 33 are squeezed and move into the third plate groove 32 on the side of the adjusting plate 31. The clamping plates 33 will move up the inclined plane of the third plate groove 32, thereby lifting the cardboard held between the two clamping plates 33, thereby reducing the weight borne by the bottom cardboard. The ball bearings 37 at both ends of the inclined plane at the bottom of the clamping plate 33 roll in contact with the bottom of the third plate groove 32, reducing the friction when the clamping plate 33 moves and making the adjustment process smoother.

[0044] like Figure 5 , Figure 6 and Figure 7As shown, the positioning plug 35 includes a positioning rod and a spring. The positioning rod is fixedly connected to the inner side of the third plate groove 32. The positioning rod is set in an inclined shape, and the inclination of the positioning rod is the same as the inclination of the inclined surface. One end of the positioning rod is movably inserted into the corresponding slot 36. The spring is sleeved on the positioning rod, and the two ends of the spring are fixedly connected to the third plate groove 32 and the clamping plate 33 respectively. The insertion and cooperation between the positioning rod and the slot 36, combined with the elasticity of the spring, can stabilize the clamping plate 33 in different adjustment positions, ensuring that the pressure on the cardboard remains constant during the die-cutting process. The spring setting enables the clamping plate 33 to automatically reset and position during adjustment.

[0045] like Figure 1 and Figure 9 As shown, the second feeding mechanism 4 includes a support frame 41, a feeding roller 42, and a second motor 43. A roller groove is formed at the top of the processing table 11, located between the conveyor belt 13 and the protective cover 21. A rotatable rotating roller 15 is installed within the roller groove, with its top extending out of the groove. The support frame 41 is mounted directly above the rotating roller 15. The feeding roller 42 is installed inside the support frame 41. The second motor 43 is mounted on one side of the support frame 41, and its output end passes through the support frame 41 and is fixedly connected to one end of the feeding roller 42. The processing table 11 is fixedly mounted on both sides, directly below the vertical portions of the support frame 41. Support plates 44 are fixedly installed, and third hydraulic rods 45 are fixedly installed at the bottom of both support plates 44. The telescopic ends of the two third hydraulic rods 45 pass through the support plates 44 and are respectively fixedly connected to the bottom of the vertical parts on both sides of the support frame 41. The height of the support frame 41 is adjusted by the third hydraulic rods 45, so that the distance between the feeding roller 42 and the rotating roller 15 can be adjusted according to the thickness of the cardboard, so as to realize the smooth transition of the cardboard from the conveyor belt 13 to the protective cover 21. The second motor 43 drives the feeding roller 42 to rotate, which cooperates with the rotating roller 15 to form a stable conveying power, ensuring that the cardboard is at a uniform speed during the transmission process and improving the continuity of production.

[0046] like Figure 3 and Figure 4 As shown, a vertical slot communicating with the first plate groove 22 is provided at the middle position of the left side of the protective cover 21. A connecting block passing through the slot is fixedly installed at the center of the top left side of the baffle 23. A first hydraulic rod 24 is fixedly installed on the left side of the protective cover 21 and above the slot. The telescopic end of the first hydraulic rod 24 is fixedly connected to the top of the connecting block. By controlling the lifting and lowering of the baffle 23 through the first hydraulic rod 24, the size of the feeding port can be precisely adjusted so that the distance between the bottom of the baffle 23 and the top of the processing table 11 is adapted to the thickness of the cardboard.

[0047] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
