Description

Technical Field

[0001] This utility model relates to the field of cardboard box die-cutting technology, and in particular to a die-cutting device for cardboard box production. Background Technology

[0002] Cardboard boxes are a widely used packaging product, primarily used to protect products, facilitate storage and transportation, and promote sales. Cardboard box die-cutting equipment is a specialized machine for die-cutting packaging materials such as cardboard boxes, cartons, and color boxes. Its main function is to use molds to creasing, cutting, and punching cardboard to meet the various shape and structural requirements of packaging products.

[0003] Existing technologies, such as CN221022536U, disclose a rapid die-cutting device for cartons, relating to the field of carton processing equipment technology. This utility model discloses a rapid die-cutting device for cartons, including a feeding rack with a feeding mechanism inside. A die-cutting mounting frame is installed on one side of the feeding rack. This utility model, through the feeding mechanism located at the bottom, allows workers to easily place cartons directly onto the carrier paper of the feeding mechanism using tools. A limiting clamp holds and positions the placed cartons during feeding, achieving a limiting function to prevent inaccurate alignment, reducing the frequency of personnel contact with the machine and improving safety. It also avoids the reduction in production efficiency caused by personnel moving back and forth. After die-cutting, the cartons are collected by a collection mechanism to facilitate centralized cleaning, keeping the production site clean, reducing the workload and intensity of production personnel, and improving production efficiency.

[0004] To address the problem of flattening and cutting cardboard using existing equipment, which requires manual hand-pushing to cut the cardboard, the operator is too close to the cutting blade, and wrinkles appear at the edges and corners of the cardboard, causing cutting errors and waste. Improvements are needed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing equipment that requires manual hand-pushing to cut cardboard, resulting in a close operating distance between the operator and the cutting blade, wrinkles appearing at the edges and corners of the cardboard, causing cutting errors and cardboard waste. The invention proposes a die-cutting device for carton production.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a die-cutting device for carton production, comprising an operating table, a support, a cutting assembly, and a transmission device. The support is fixedly connected to the lower surface of the operating table. The cutting assembly is disposed on the surface of the operating table. A fixed frame is provided on the operating table, and the fixed frame is fixed to the surface of the operating table. A transmission device is disposed on the surface of the fixed frame, and the transmission device includes a transmission wheel. A rotating rod is rotatably connected to the surface of the fixed frame. A rotating plate is fixedly connected to the surface of the rotating rod, and the transmission wheel is disposed on the surface of the rotating plate.

[0007] Furthermore, a limit block is fixedly connected to the surface of the rotating rod, and the number of the limit blocks is two sets, which are arranged symmetrically.

[0008] Furthermore, a torsion spring is fixedly connected to the surface of the limiting block, the torsion spring is sleeved and connected to the surface of the rotating rod, and the end of the torsion spring away from the limiting block is fixedly connected to the surface of the rotating plate.

[0009] Furthermore, a stabilizing block is fixedly connected to the surface of the rotating plate, a pull rod is fixedly connected to the surface of the stabilizing block, a rotating shaft is rotatably connected to the inner wall of the stabilizing block, and a transmission wheel is fixedly connected to the surface of the rotating shaft.

[0010] Furthermore, the surface of the operating table is provided with a flattening device, which includes a support block. The support block is fixedly connected to the surface of the operating table, and a feed roller is rotatably connected to the surface of the support block.

[0011] Furthermore, a fixing block is fixedly connected to the surface of the operating table, a tension spring is fixedly connected to the lower surface of the fixing block, and a connecting plate is fixedly connected to the end of the tension spring away from the fixing block.

[0012] Furthermore, a long rod is fixedly connected to the upper surface of the connecting plate, the long rod is sleeved and connected to the inner wall of the fixing block, a rotating column is fixedly connected to the upper surface of the long rod, and a pressure roller is rotatably connected to the surface of the rotating column.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a transmission device, the use of the drive wheel is more convenient when feeding cardboard. Pulling the pull rod causes the pull rod to drive the rotating plate to rotate stably along the axis of the rotating rod, thereby causing the torsion spring to deform under force. Then, when the cardboard is pressed and pulled onto the operating table by the pressure roller, the pull rod is released, causing the torsion spring to lose force and deform, driving the rotating plate to rotate stably along the axis of the rotating rod. Then, the drive wheel contacts the surface of the cardboard, and the drive wheel rotates stably along the axis of the rotating shaft, so that the cardboard is stably transmitted. By setting up a transmission device, it is convenient to feed cardboard, avoiding the need for manual hand-pushing to cut the cardboard in existing equipment, which results in the operator being too close to the cutting blade. This effectively improves the ease of use of the equipment.

[0015] 2. In this utility model, by setting a flattening device, it is easier to flatten the cardboard and make the use of the pressure roller more convenient. To this end, the connecting plate is pushed upward, causing the connecting plate to push the pressure roller to move upward, thereby compressing the tension spring. Then, the cardboard passes through the feeding roller and passes under the pressure roller. Then, the connecting plate is released, causing the tension spring to stretch and expand after losing its force, so that the pressure roller presses against the surface of the cardboard, thereby flattening the cardboard. By setting a flattening device, it is easy to flatten the cardboard and avoid wrinkles at the edges and corners of the cardboard, which would cause cutting errors and waste of cardboard. This effectively improves the practicality of the equipment. Attached Figure Description

[0024] Please see Figures 1-6 This utility model provides a technical solution: a die-cutting device for carton production, including an operating table 1, a support 2, a cutting component 3 and a transmission device 4. The support 2 is fixedly connected to the lower surface of the operating table 1. The cutting component 3 is disposed on the surface of the operating table 1. A fixing frame 41 is provided on the operating table 1. The fixing frame 41 is fixed to the surface of the operating table 1. The transmission device 4 is disposed on the surface of the fixing frame 41.

[0025] The specific setup and function of the transmission device 4 and the flattening device 5 will be explained below.

[0026] In this embodiment: the transmission device 4 includes a transmission wheel 49, and a rotating rod 42 is rotatably connected to the surface of the fixed frame 41. A rotating plate 43 is fixedly connected to the surface of the rotating rod 42, and the transmission wheel 49 is disposed on the surface of the rotating plate 43.

[0027] Specifically, a limit block 44 is fixedly connected to the surface of the rotating rod 42, and there are two sets of limit blocks 44 arranged symmetrically.

[0028] Specifically, a torsion spring 45 is fixedly connected to the surface of the limiting block 44, and the torsion spring 45 is sleeved and connected to the surface of the rotating rod 42. The end of the torsion spring 45 away from the limiting block 44 is fixedly connected to the surface of the rotating plate 43.

[0029] Specifically, a stabilizing block 46 is fixedly connected to the surface of the rotating plate 43, a pull rod 47 is fixedly connected to the surface of the stabilizing block 46, a rotating shaft 48 is rotatably connected to the inner wall of the stabilizing block 46, and a transmission wheel 49 is fixedly connected to the surface of the rotating shaft 48.

[0030] The effects achieved by the above components are as follows: by setting the rotating rod 42, the rotating plate 43 can be stably rotated along the axis of the rotating rod 42; by setting the torsion spring 45, the rotating plate 43 can be restored to its original shape after the rotating plate 43 loses its force, so that the rotating plate 43 can be rotated and reset, so that the rotating plate 43 is parallel to the operating table 1; and by setting the transmission wheel 49, the cardboard placed on the operating table 1 can be transmitted and fed.

[0031] Specifically, the surface of the operating table 1 is provided with a flattening device 5, which includes a support block 51. The support block 51 is fixedly connected to the surface of the operating table 1, and a feed roller 52 is rotatably connected to the surface of the support block 51.

[0032] Specifically, a fixing block 53 is fixedly connected to the surface of the operating table 1, a tension spring 54 is fixedly connected to the lower surface of the fixing block 53, and a connecting plate 55 is fixedly connected to the end of the tension spring 54 away from the fixing block 53.

[0033] Specifically, a long rod 56 is fixedly connected to the upper surface of the connecting plate 55, the long rod 56 is sleeved and connected to the inner wall of the fixing block 53, a rotating column 57 is fixedly connected to the upper surface of the long rod 56, and a pressure roller 58 is rotatably connected to the surface of the rotating column 57.

[0034] The effects achieved by the above components are as follows: the feed roller 52 is provided to prevent the cardboard from rubbing against the corner of the operating table 1, avoid excessive friction, and prevent the cardboard from being damaged. The tension spring 54 is provided so that after the connecting plate 55 loses its force, the rebound force of the tension spring 54 can drive the pressure roller 58 to press down, so that the pressure roller 58 can stably flatten the cardboard and prevent the cardboard from wrinkling.

[0035] Working principle: By setting up the transmission device 4, the use of the roller is more convenient when feeding the cardboard. Pulling the pull rod 47 causes the rotating plate 43 to rotate stably along the axis of the rotating rod 42. The torsion spring 45 is then deformed by the force, and the cardboard is pressed and pulled onto the operating table 1 by the pressure roller 58. When the pull rod 47 is released, the torsion spring 45 loses its force and deforms, causing the rotating plate 43 to rotate stably along the axis of the rotating rod 42. Then the transmission wheel 49 contacts the surface of the cardboard and rotates stably along the axis of the rotating shaft 48, so that the cardboard is stably transmitted. By setting up the transmission device 4, the feeding of the cardboard is facilitated, avoiding the need for manual hand-pushing to cut the cardboard in existing equipment, which results in the operator being too close to the cutting blade. This effectively improves the ease of use of the equipment.

[0036] Furthermore, by setting up the flattening device 5, the flattening of the cardboard is facilitated, and the use of the pressure roller 58 is made more convenient. To this end, the connecting plate 55 is pushed upward, causing the connecting plate 55 to push the pressure roller 58 to move upward, thereby compressing the tension spring 54. Then, the cardboard passes through the feed roller 52 and passes under the pressure roller 58. Then, the connecting plate 55 is released, causing the tension spring 54 to stretch and expand after losing its force, so that the pressure roller 58 presses against the surface of the cardboard, thereby flattening the cardboard. By setting up the flattening device 5, the cardboard is easily flattened, avoiding wrinkles at the edges and corners of the cardboard, which would cause cutting errors and waste of cardboard. This effectively improves the practicality of the equipment.
