Description

Technical Field

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

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, and CNC punching machines, are mainly used for cutting non-metallic materials, self-adhesive labels, EVA, and double-sided adhesives. Using steel blades, metal molds, and steel wire, and applying pressure through a printing plate, die-cuts printed materials or cardboard into specific shapes. Die-cutting machines are an important processing and forming equipment. During the die-cutting process of cartons, various waste chips are generated. If these chips are not removed from the material surface, they will enter the next process with the material, damaging subsequent equipment and affecting further processing of the cartons, thus failing to meet the requirements of current carton processing.

A housing is fixedly connected to the top of the base plate via a support plate. Rotary rods are movably connected to the top and bottom of the right side of the housing via fixed plates. A transmission roller is fixedly connected to the surface of the rotary rod. A first motor is fixedly connected to the top of the right side of the housing, and a first transmission wheel is fixedly connected to the output end of the first motor. A second transmission wheel is fixedly connected to the front side of the rotary rod surface. This invention, through the cooperation of the base plate, housing, rotary rod, transmission roller, first motor, first transmission wheel, second transmission wheel, box body, guide plate, rotating shaft, die-cutting roller, die-cutting plate, second motor, partition, filter box, fan, scraper, dust collection plate, and guide block, enables the cardboard box die-cutting waste removal device to clean the surface of the die-cut cardboard box through a dust removal mechanism, preventing waste from the cardboard box surface from affecting subsequent processing, thereby improving the efficiency of cardboard box die-cutting.

[0004] Traditional die-cutting machines require manual tool replacement or mold position adjustment, resulting in long changeover times and cumbersome operation. Traditional die-cutting equipment requires separate conveying, cutting, and waste removal processes, leading to low efficiency and residual debris. Utility Model Content

[0005] The purpose of this invention is to solve the problems of traditional die-cutting machines, which require manual replacement of blades or adjustment of mold positions, resulting in long changeover times and cumbersome operation. Traditional die-cutting equipment requires separate conveying, cutting and waste removal processes, resulting in low efficiency and residual debris. Therefore, a waste removal device for carton die-cutting is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cardboard box die-cutting waste removal device, comprising:

[0008] The die-cutting box contains, from left to right, a conveying mechanism, a die-cutting plate, two L-shaped cleaning plates, and a rectangular guide tube. The top of the die-cutting plate is flush with the top edge of the conveying mechanism. The two L-shaped cleaning plates are fixedly installed on the side wall of the die-cutting box. A controller is located on the outside of the die-cutting box.

[0009] The carton limiting mechanism is located on the top inner wall of the die-cutting box and above the conveying mechanism;

[0010] The spacing adjustment mechanism is installed on the die-cutting box and located above the die-cutting plate. Two die-cutting mechanisms are installed on the spacing adjustment mechanism and are located above the die-cutting plate.

[0011] Preferably, the conveying mechanism includes two conveying rollers, which are rotatably mounted on the die-cutting box via bearings. The same conveyor belt is sleeved on the outer side of the two conveying rollers. A servo motor is mounted on the outer side of the die-cutting box, and the output shaft of the servo motor is fixedly mounted to one of the conveying rollers.

[0012] Preferably, the carton limiting mechanism includes two first linear motors, both of which are fixedly installed on the top inner wall of the die-cutting box. The output shafts of the two first linear motors are equipped with the same first slide rail, and a first slider is slidably installed in each of the two first slide rails. A limiting plate is fixedly installed at the bottom of each of the two first sliders.

[0013] Preferably, a first bidirectional screw is rotatably mounted inside the first slide rail, two first sliders are threadedly connected to the two ends of the first bidirectional screw, a first motor is mounted on the outside of the first slide rail, and the output shaft of the first motor is fixedly mounted to the outer end of the first bidirectional screw.

[0014] Preferably, the spacing adjustment mechanism includes two second linear motors, both of which are mounted on the top of the die-cutting box. The output shafts of the two second linear motors are equipped with the same second slide rail, which is located inside the die-cutting box. Two second sliders are slidably mounted inside the second slide rail, and two die-cutting mechanisms are mounted at the bottom of the two second sliders.

[0015] Preferably, a second bidirectional screw is rotatably mounted inside the second slide rail, two second sliders are threadedly connected to the two ends of the second bidirectional screw, a second motor is fixedly mounted on the outside of the second slide rail, and the output shaft of the second motor is fixedly mounted to the outer end of the second bidirectional screw.

[0016] Preferably, the die-cutting mechanism includes a spacing adjustment plate, which is fixedly installed on the bottom of the second slider. A die-cutting motor is fixedly installed on the spacing adjustment plate. A circular roller is installed on the output shaft of the die-cutting motor. A ring-shaped blade is installed on the outer side of the circular roller. Multiple arc-shaped cotton pads are fixedly installed on the outer side of the circular roller. Multiple support cylinders are fixedly installed on the outer end of the circular roller. A buffer rod is slidably installed inside each of the multiple support cylinders. A spring is fixedly installed between the buffer rod and the support cylinder. A circular rubber head is fixedly installed on the outer end of the buffer rod.

[0017] The beneficial effects of the cardboard box die-cutting waste removal device described in this utility model are as follows:

[0018] 1. Dual-die cutting blade spacing automatic adjustment system (through a bidirectional screw and linear motor working in tandem): The second motor drives the bidirectional screw to rotate, causing the two second sliders to move synchronously in opposite directions, achieving precise adjustment of the spacing between the two die-cutting mechanisms. The second linear motor controls the lifting and lowering of the entire slide rail, adapting to cardboard of different thicknesses.

[0019] 2. Die-cutting, conveying, and waste removal three-in-one rotating roller design (integrating a ring blade, cotton pad, and buffer rubber head). The roller integrates three main functional components: a ring blade for rotating and cutting the cardboard; an arc-shaped cotton pad that pushes the cardboard forward during rotation, avoiding secondary positioning; and a buffer rod + round rubber head: a spring-loaded structure that rotates in contact with the cardboard surface, pulling the cutting debris outwards. The round rubber head is connected to the support cylinder via the buffer rod and spring, providing elastic pressure during waste removal. This avoids rigid contact that could damage the cardboard surface while ensuring effective debris removal.

[0020] 3. Dynamic limiting mechanism (adaptive limiting plate driven by bidirectional screw): The carton limiting mechanism drives two first sliders to move synchronously in opposite directions via a first bidirectional screw, thereby adjusting the spacing of the limiting plate. A first linear motor controls the overall lifting and lowering of the limiting mechanism to adapt to different cardboard thicknesses.

[0021] 4. The L-shaped cleaning plate is fixed to the side wall of the die-cutting box to block splashing debris and guide it downwards. After the debris falls to the bottom of the die-cutting box, it is collected and discharged by the rectangular guide pipe, achieving residue-free collection.

[0022] This utility model features automated adjustable spacing / limit self-adaptation, reducing changeover time and integrating cutting, conveying, and waste removal into one unit, saving process flow time. Attached Figure Description
