Description

Technical Field

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

[0002] Corrugated cardboard is die-cut, creasing, and nailed or glued to make corrugated boxes. Corrugated boxes are one of the most widely used packaging products. With their superior performance and good processing properties, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers, becoming the mainstay of transport packaging. In the production process of corrugated boxes, a die-cutting machine is needed to die-cut the corrugated paper material.

[0003] Existing die-cutting equipment for corrugated boxes has the following drawbacks: Old-fashioned corrugated paper die-cutting machines, also known as die-cutting machines, adopt a semi-automatic production method. Because of their simple structure and low cost, they are still widely used. Before processing, positioning blocks need to be glued to the surface of the placement table. The positioning blocks are fixed according to the specifications of the corrugated cardboard to be die-cut and the corrugated cardboard is positioned by the positioning blocks. During the die-cutting process, manual assistance is required, and two processes, unloading and loading, need to be completed. The operation is cumbersome and increases the danger. Therefore, we propose a cardboard die-cutting device for corrugated boxes. Utility Model Content

[0004] The main purpose of this utility model is to provide a cardboard die-cutting device for corrugated boxes. By improving the surface of the die-cutting machine body, it achieves top feeding and bottom discharge, which can simplify the amount of manual labor in the die-cutting process, improve efficiency and operational safety, and effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cardboard die-cutting device for corrugated boxes includes a die-cutting machine body and a material feeding mechanism. The material feeding mechanism is provided on the side of the die-cutting machine body. The material feeding mechanism includes a placement platform, a fixed plate, a horizontal plate, a movable plate, a fixed ring, a tray, a connecting shaft, and a torsion spring. The placement platform is hinged to the side of the die-cutting machine body, and fixed plates are movably connected to both sides of the placement platform. A horizontal plate extending to the top of the placement platform is integrally formed on the top of the fixed plate, and movable plates are movably connected to the ends of the horizontal plate. A fixed ring is welded to the end of the movable plate away from the horizontal plate, and a tray is movably connected to the fixed ring. A connecting shaft inserted into the fixed ring is welded to the side of the tray, and a torsion spring is installed between the outer wall of the connecting shaft and the surface of the movable plate.

[0007] Furthermore, it also includes an adjustment mechanism. An adjustment mechanism is provided at the connection between the placement platform and the movable plate. The adjustment mechanism includes screw hole A, screw rod, slot, insert plate, screw hole B, bolt, and pressure ring. Screw holes A are provided on both sides of the end of the placement platform, and screw rods are screwed into screw holes A. Slots are provided inside the horizontal plate, and insert plates are fixedly connected to the end of the movable plate and inserted into the slots. Screw holes B are provided inside the horizontal plate, and bolts are screwed into screw holes B. A pressure ring is welded to the end of the bolt and fits against the surface of the insert plate. By turning the screw rod through screw hole A at the end of the placement platform, the screw rod will drive the slider to move along the inside of the slide groove, thereby adjusting the position of the tray on the surface of the placement platform. Loosening the bolt allows the movable plate to be pulled horizontally at the end of the fixed plate to adjust the distance between the trays. After reaching the appropriate position, tighten the bolt through screw hole B so that the pressure ring presses against the surface of the insert plate, thus fixing the position of the tray. It is convenient to use and flexible to adjust.

[0008] Furthermore, both sides of the placement platform surface are provided with sliding grooves and sliders are slidably connected through the sliding grooves, and the fixing plate is fixed to the surface of the slider; the cooperation between the sliding groove and the slider facilitates the adjustment of the position of the tray along the side of the placement platform and at the same time provides a certain limiting effect on the tray.

[0009] Furthermore, a pin is inserted at the connection between the fixing ring and the connecting shaft; the pin structure connects and fixes the fixing ring and the connecting shaft together without affecting the rotation of the connecting shaft.

[0010] Furthermore, a conveyor belt is horizontally laid at the bottom of the die-cutting machine body, and the end of the conveyor belt is inserted into the interior of the die-cutting machine body; the conveyor belt runs under the action of an external motor, and the corrugated cardboard that has been die-cut and discharged will fall onto the surface of the conveyor belt and be discharged by the conveyor belt to complete the automatic material discharge.

[0011] Furthermore, the end of the screw is connected to the slider, and a connecting ring located inside the slider is welded to the end of the screw; the connecting ring is embedded in the internal cavity of the slider, and the end of the screw extends into the cavity and is welded and fixed to the connecting ring, so that the turning of the screw can drive the slider to move along the slide groove.

[0012] Compared with the prior art, this utility model has the following beneficial effects: The main body of the die-cutting machine is structurally improved by opening a sliding groove on the side of the placement table and installing a positioning component. The position of the fixed plate on the surface of the placement table is adjusted according to the specifications of the corrugated cardboard to be die-cut, while ensuring alignment between the fixed plates on both sides of the placement table. Then, the distance between the movable plate and the fixed plate is adjusted, which in turn drives the adjustment of the distance between the pallets. When the pallet position is adjusted to the correct position, the corrugated cardboard to be die-cut is placed on the surface of the placement table, and the two ends of the cardboard are respectively attached to the surfaces of the pallet and the movable plate, thus completing the adjustment of the positioning component. The thickness of the fixed plate, movable plate, and pallet is less than the thickness of the cardboard, so it does not affect the die-cutting process. During die-cutting, the main body of the die-cutting machine operates under the action of the power component. Under normal operating conditions, the surface of the pallet is perpendicular to the end of the movable plate to support the cardboard. After the cardboard is placed on top, positioning is completed and die-cutting is performed. After die-cutting, the placement table is opened, and at this time, only the new cardboard to be die-cut needs to be placed... Align the top of the die-cut cardboard with the top of the die-cut cardboard and push it. The bottom of the cardboard will be pressed, squeezing the tray and causing it to deflect around the connecting shaft until the tray is fully open. The cardboard can then be discharged from the bottom of the placement table. After the cardboard is discharged, the tray will automatically reset under the action of the torsion spring and fit against the surface of the movable plate, making it easy to put in the cardboard to be processed later. This simplifies the material feeding process during die-cutting, realizing top feeding and bottom discharge, which can reduce the amount of manual labor in the die-cutting process and improve efficiency and operational safety. Tighten the screw through the screw hole A at the end of the placement table. When the screw is turned, it will drive the slider to move along the inside of the slide groove, thereby adjusting the position of the tray on the surface of the placement table. Loosen the bolt, and the movable plate can be pulled horizontally at the end of the fixed plate to adjust the distance between the trays. After reaching the appropriate position, tighten the bolt through the screw hole B, so that the pressure ring presses against the surface of the insert plate, thus fixing the position of the tray. It is convenient to use and flexible to adjust. Attached Figure Description

[0019] 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.

[0020] like Figure 1-5 As shown, a cardboard die-cutting device for corrugated boxes includes a die-cutting machine body 1 and a material feeding mechanism 2. The material feeding mechanism 2 is provided on the side of the die-cutting machine body 1. The material feeding mechanism 2 includes a placement platform 201, a fixed plate 204, a horizontal plate 205, a movable plate 206, a fixed ring 207, a support plate 208, a connecting shaft 209, and a torsion spring 211. The placement platform 201 is hinged to the side of the die-cutting machine body 1, and the fixed plates 204 are movably connected to both sides of the placement platform 201. The top of the fixed plate 204 is integrally formed with a horizontal plate 205 extending to the top of the placement platform 201, and the ends of the horizontal plate 205 are movably connected to the movable plate 206. A fixed ring 207 is welded to the end of the movable plate 206 away from the horizontal plate 205, and a support plate 208 is movably connected to the fixed ring 207. A connecting shaft 209 is welded to the side of the support plate 208 and inserted into the interior of the fixed ring 207. A torsion spring 211 is installed between the outer wall of the connecting shaft 209 and the surface of the movable plate 206.

[0021] The system also includes an adjustment mechanism 3. An adjustment mechanism 3 is provided at the connection between the placement platform 201 and the movable plate 206. The adjustment mechanism 3 includes a screw hole A301, a screw 302, a slot 304, an insert plate 305, a screw hole B306, a bolt 307, and a pressure ring 308. Screw holes A301 are provided on both sides of the end of the placement platform 201, and screws 302 are screwed into the screw holes A301. A slot 304 is provided inside the horizontal plate 205, and an insert plate 305 inserted into the slot 304 is fixedly connected to the end of the movable plate 206. A screw hole B306 is provided inside the horizontal plate, and a bolt 307 is screwed into the screw hole B306. The bolt 307 has a pressure ring 308 welded to its end and attached to the surface of the insert plate 305. The screw 302 is turned along the screw hole A301 at the end of the placement platform 201. Turning the screw 302 causes the slider 203 to move along the inside of the slide groove 202, thereby adjusting the position of the support plate 208 on the surface of the placement platform 201. Loosening the bolt 307 allows the movable plate 206 to be pulled horizontally at the end of the fixed plate 204, adjusting the distance between the support plates 208. Once the desired position is reached, the bolt 307 is tightened along the screw hole B306, pressing the pressure ring 308 against the surface of the insert plate 305, thus fixing the position of the support plate 208. This method is convenient to use and allows for flexible adjustment.

[0022] The placement platform 201 has sliding grooves 202 on both sides of its surface, and a slider 203 is slidably connected to the sliding grooves 202. The fixing plate 204 is fixed to the surface of the slider 203. The cooperation between the sliding grooves 202 and the slider 203 facilitates the adjustment of the position of the tray 208 along the side of the placement platform 201, and at the same time plays a certain limiting role for the tray 208.

[0023] A pin 210 is inserted at the connection between the fixing ring 207 and the connecting shaft 209. A conveyor belt 212 is horizontally laid at the bottom of the die-cutting machine body 1, and the end of the conveyor belt 212 is inserted into the interior of the die-cutting machine body 1. The pin 210 structure connects and fixes the fixing ring 207 and the connecting shaft 209 together without affecting the rotation of the connecting shaft 209. The conveyor belt 212 operates under the action of an external motor. The corrugated cardboard that has been die-cut and discharged will fall onto the surface of the conveyor belt 212 and be discharged by the conveyor belt 212 to complete the automatic material discharge.

[0024] The screw 302 is connected to the slider 203 at its end, and a connecting ring 303 located inside the slider 203 is welded to the end of the screw 302. The connecting ring 303 is embedded in the cavity inside the slider 203, and the end of the screw 302 extends into the cavity and is welded and fixed to the connecting ring 303, so that the turning of the screw 302 can drive the slider 203 to move along the slide groove 202.

[0025] It should be noted that this utility model is a cardboard die-cutting device for corrugated boxes. In use, the die-cutting machine body 1 is structurally improved by creating a sliding groove 202 on the side of the placement table 201 and installing a positioning component. The position of the fixing plate 204 on the surface of the placement table 201 is adjusted according to the specifications of the corrugated cardboard to be die-cut, while ensuring alignment between the fixing plates 204 on both sides of the placement table 201. Then, the distance between the movable plate and the fixing plate 204 is adjusted, which in turn drives the adjustment of the distance between the pallets 208, so that when the pallets 208 are in the correct position, the corrugated cardboard to be die-cut is placed on the placement table. After the cardboard is placed on the surface of the platform 201, the two ends of the cardboard are respectively attached to the surfaces of the support plate 208 and the movable plate 206, thus completing the adjustment of the positioning components. The thickness of the fixed plate 204, the movable plate 206, and the support plate 208 is less than the thickness of the cardboard, which does not affect the die-cutting process. During the die-cutting process, the main body 1 of the die-cutting machine operates under the action of the power component. Under normal use, the surface of the support plate 208 is perpendicular to the end of the movable plate 206 to support the cardboard. After the cardboard is placed on top, it is positioned and die-cut. After the die-cutting is completed, the platform 201 is opened. At this time, simply place the new paper to be die-cut. The plate is aligned with the top of the die-cut cardboard and pushed. The pressure on the bottom of the cardboard squeezes the tray 208, causing it to deflect around the mounting position of the connecting shaft 209 until the tray 208 is fully open. The cardboard can then be discharged from the bottom of the placement table 201. After discharge, the tray 208 automatically resets under the action of the torsion spring 211 and adheres to the surface of the movable plate 206, facilitating the placement of subsequent cardboard pieces. This simplifies the material feeding process during die-cutting, enabling top loading and bottom unloading, reducing manual labor and improving efficiency and operational safety. The screw hole A301 at the end of the placement platform 201 is used to screw the screw 302. When the screw 302 is screwed, it will drive the slider 203 to move along the inside of the slide groove 202, thereby driving the adjustment plate 208 to move on the surface of the placement platform 201. Loosen the bolt 307, and the movable plate 206 can be pulled horizontally at the end of the fixed plate 204 to adjust the distance between the plates 208. After reaching the appropriate position, tighten the bolt 307 along the screw hole B306 so that the pressure ring 308 is pressed against the surface of the insert plate 305, thus fixing the position of the plate 208. It is convenient to use and flexible to adjust.
