Abstract
Description
Technical Field
[0001] This utility model relates to the field of creasing device technology, specifically to an automatic creasing device for packaging cartons. Background Technology
[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc. In the cardboard box production process, in order to make the cardboard easy to fold into a cardboard box, it is often necessary to crease the cardboard. The creases facilitate the assembly of the cardboard.
[0003] Existing creasing devices require manual placement of cardboard onto the creasing mold, creasing, and then removal of the cardboard for replacement. This process is not only inefficient but also poses a risk of hand injury due to the pressure between the molds, resulting in poor safety. Therefore, an automatic creasing device for packaging cartons is proposed. Utility Model Content
[0004] The purpose of this invention is to provide an automatic creasing device for packaging cartons to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic creasing device for packaging cartons, comprising a worktable, a pair of support rails fixedly connected to the upper surface of the worktable, drive rollers rotatably connected to the inner sidewalls of the support rails, a stacking frame fixedly connected to the upper surface of the support rails, cardboard evenly distributed on the inner sidewalls of the stacking frame, a discharge port on the right sidewall of the stacking frame, a baffle fixedly connected to the upper surface of the support rails, pressure rollers rotatably connected to the inner sidewalls of the baffle, a gantry fixedly connected to the upper surface of the worktable, an electric push rod mounted on the upper surface of the gantry, a lifting plate on the lower side of the gantry, the upper surface of the lifting plate fixedly connected to the output end of the electric push rod, a creasing knife mounted on the lower surface of the lifting plate, a pressure seat on the lower side of the lifting plate, and a creasing groove on the upper surface of the pressure seat.
[0006] As a further preferred embodiment of this technical solution: the inner side wall of the palletizing rack is chamfered on the right side.
[0007] As a further preferred embodiment of this technical solution: a sprocket is fixedly connected to the outer side wall of the drive roller, a chain is installed on the outer side wall of the sprocket, a servo motor is installed on the upper surface of the worktable, and the output end of the servo motor is fixedly connected to the front end of one of the drive rollers.
[0008] As a further preferred embodiment of this technical solution: a transmission shaft is fixedly connected between two longitudinally opposite drive rollers.
[0009] As a further preferred embodiment of this technical solution: the lower surface of the workbench is fixedly connected with evenly distributed support legs.
[0010] As a further preferred embodiment of this technical solution: a pair of sliding rods are slidably connected to the inner side wall of the gantry frame, the lower end of the sliding rods is fixedly connected to the upper surface of the lifting plate, an anti-detachment block is fixedly connected to the upper end of the sliding rods, and a spring is fixedly connected between the lower surface of the anti-detachment block and the upper surface of the gantry frame.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In use, multiple sheets of cardboard are placed flat in the stacking rack, with the bottom layer tangent to the outer wall of the drive roller. The drive roller moves the cardboard to the right, and the stacking rack prevents the cardboard from being conveyed out one by one. The chamfering facilitates the bottom layer of cardboard passing through the discharge port. The baffles on both sides limit the front and rear sides of the cardboard to prevent deviation. When the cardboard is conveyed to the pressure seat, the conveying stops. At this time, the pressure roller can limit the upper part of the cardboard. The electric push rod is activated to move the lifting plate downward, so that the creasing knife presses down on the cardboard. With the corresponding creasing groove, the cardboard is creased. After completion, the drive roller continues to start, which facilitates the creasing work of the next cardboard. There is no need to frequently put in cardboard, which improves work efficiency. No manual operation is required, which is less likely to cause injury to the hands and is highly safe. Attached Figure Description

The surface is provided with a creasing groove 14. In use, multiple sheets of cardboard 5 are placed flat in the stacking rack 4, with the bottom layer of cardboard 5 tangent to the outer wall of the drive roller 3. The drive roller 3 drives the cardboard 5 to move to the right. The thickness of a single sheet of cardboard 5 is equal to that of the discharge port 6. Under the obstruction of the stacking rack 4, the drive roller 3 drives the cardboard 5 to be conveyed one by one. The front and rear sides of the cardboard 5 are limited by the baffles 7 on both sides to prevent deviation. When the cardboard 5 is conveyed to the pressure seat 13, the conveying stops. At this time, the pressure roller 8 can limit the upper part of the cardboard 5. The electric push rod 10 is activated to drive the lifting plate 11 to move downward, so that the creasing knife 12 presses down on the cardboard 5. With the corresponding creasing groove 14, the cardboard 5 is creasing. After completion, the drive roller 3 continues to open, which facilitates the creasing work of the next sheet of cardboard 5. It is not necessary to frequently put in the cardboard 5, which improves the work efficiency. No manual operation is required, which is less likely to cause injury to the hands and is highly safe.
[0023] In this embodiment, specifically: the inner side wall of the stacking rack 4 is provided with a chamfer 15 on the right side; the chamfer 15 facilitates the bottom layer of cardboard 5 to pass through the discharge port 6.

The sliding rods 21 can improve the stability of the descent of the lifting plate 11, and the spring 23 can provide buffering when the indentation knife 12 is pressed down.
[0028] The working principle of this utility model is as follows: In use, multiple sheets of cardboard 5 are placed flat in the stacking rack 4, with the bottom layer of cardboard 5 tangent to the outer wall of the drive roller 3. The servo motor 18 is started to precisely control the rotation of one drive roller 3. Under the action of the sprocket 16, chain 17, and drive shaft 19, all drive rollers 3 on both sides can rotate synchronously, achieving the effect of one servo motor 18 driving multiple drive rollers 3 on both sides to rotate simultaneously. The drive rollers 3 move the cardboard 5 to the right, with the thickness of a single cardboard 5 equal to the discharge port 6. Under the obstruction of the stacking rack 4, the drive rollers 3 carry the cardboard 5 out one sheet at a time, chamfering the edges. 15 facilitates the passage of the bottom cardboard 5 through the discharge port 6. The baffles 7 on both sides limit the front and rear sides of the cardboard 5 to prevent deviation. When the cardboard 5 is conveyed to the pressure seat 13, the conveying stops. At this time, the pressure roller 8 can limit the upper part of the cardboard 5. The electric push rod 10 is activated to drive the lifting plate 11 to move downward, so that the creasing knife 12 presses down on the cardboard 5. With the corresponding creasing groove 14, the cardboard 5 is creasing. After completion, the drive roller 3 continues to open, which facilitates the creasing work of the next cardboard 5. There is no need to frequently put in the cardboard 5, which improves the work efficiency. No manual operation is required, which is less likely to cause injury to the hands and is highly safe.
