Description
Technical Field
[0001] This utility model belongs to the technical field of corrugated cardboard box processing equipment, and in particular relates to a creasing device for forming the inner lining of corrugated cardboard boxes. Background Technology
[0002] Corrugated cardboard boxes, with their advantages of being lightweight, pressure-resistant, and recyclable, have become the mainstream packaging carrier in logistics warehousing and product packaging. As a core supporting structure, the inner lining of the cardboard box is mainly used for cushioning and protection, limiting and fixing products, and ensuring the integrity of goods during transportation. The forming of the inner lining requires a special forming device to complete the bending and shaping of the cardboard. The creasing is a core pre-processing step in the forming of the inner lining. The creasing device can press out regular creases at preset positions on the corrugated cardboard, standardize the bending trajectory of the cardboard, and ensure the regularity and structural stability of the inner lining. It is a key supporting equipment to ensure the standardization and high-precision forming of the inner lining of the cardboard box and is widely used in various corrugated cardboard box inner lining processing production lines.
[0003] However, when the existing lining forming pressing device is used continuously, the pressing roller will press on the rubber roller for a long time. Due to long-term single-point wear, the rubber roller will develop annular grooves. These annular grooves will affect the normal pressing of subsequent products, thereby reducing the overall forming quality of the lining. Utility Model Content
[0004] The purpose of this invention is to provide a creasing device for corrugated carton lining forming. By setting a moving part, it solves the problem that in existing creasing devices for lining forming, the creasing roller will press on the rubber roller for a long time during continuous use, and the rubber roller will develop annular grooves due to long-term single-point wear. These annular grooves will affect the normal creasing of subsequent products, thereby reducing the overall forming quality of the lining.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a creasing device for forming the inner lining of corrugated cardboard boxes, comprising a housing and a worktable fixedly connected to the inner wall of the housing, and further comprising: a movable part installed inside the housing; an opening and closing part disposed inside the housing; the movable part including a translation component installed inside the housing; and a transmission component disposed inside the housing; the translation component including a motor fixedly connected to the inner wall of the housing, a rotating shaft rotatably connected to the inner wall of the housing, and the output shaft of the motor fixedly connected to the rotating shaft via a coupling. The wall has two receiving slots, and the two receiving slots extend to the outside of the chassis on the side closest to each other. A cross block is fixedly connected to the outer wall of the first rotating shaft, and a rubber roller is slidably connected to the outer wall of the cross block. A rotating block is fixedly connected to the left side of the rubber roller, and a rotating block is rotatably connected to the inner wall of the first rotating block. A chamfered block is fixedly connected to the left side of the second rotating block. An electric telescopic rod is fixedly connected to the inner wall of the chassis, and the output end of the electric telescopic rod is fixedly connected to the chamfered block. The right side of the first rotating shaft extends to the outside of the chassis, and the inner diameter of the receiving slot is slightly larger than the diameter of the rubber roller.
[0006] Furthermore, the opening and closing part includes a lifting assembly installed inside the chassis; and a rotating assembly disposed inside the chassis.
[0007] Furthermore, the transmission assembly includes two rotating shafts rotatably connected to the inner wall of the chassis. The right sides of both rotating shafts extend to the outside of the chassis. Transmission rollers are fixedly connected to the outer walls of both rotating shafts. A power component is provided on the right side of both rotating shafts. The two transmission rollers are mirror images of each other and are arranged vertically. The power component includes two gears fixedly connected to the outer walls of the two rotating shafts respectively. A motor is fixedly connected to the inner wall of the chassis. The output shaft of the motor is fixedly connected to the rotating shaft below via a coupling.
[0008] Furthermore, the lifting assembly includes two sliding grooves formed on the inner wall of the chassis. The inner walls of both sliding grooves are slidably connected to brackets. A lifting component is arranged between the two brackets. The two sliding grooves are mirror images of each other. The right side of the right sliding groove extends to the outside of the chassis. The lifting component includes a connecting plate fixedly connected to one side of the two brackets that are close to each other. An electric telescopic rod II is fixedly connected to the inner wall of the chassis. The output end of the electric telescopic rod II is fixedly connected to the connecting plate. The top of the electric telescopic rod II is the output end.
[0009] Furthermore, the rotating assembly includes a motor three fixedly connected to the right side of the right bracket, a rotating shaft three rotatably connected to the inner walls of the two brackets, an extrusion member provided on the rotating shaft three, the rotating shaft three passing through the bracket, the output shaft of the motor three being fixedly connected to the rotating shaft three via a coupling, the extrusion member including an extrusion roller fixedly connected to the outer wall of the rotating shaft three, and a plurality of pressure rollers fixedly connected to the outer wall of the extrusion roller, the plurality of pressure rollers being arranged in an array.
[0010] This utility model has the following beneficial effects: 1. By setting up a moving part, after the equipment completes the batch cardboard creasing process, the opening and closing part loosens the contact between the creasing roller and the rubber roller. The moving part drives the rubber roller to move laterally through its own structure, changing the working position of the rubber roller. This changes the squeezing contact area between the creasing roller and the rubber roller, completing the switching operation of the pressure position of the rubber roller. It can change the squeezing contact position between the rubber roller and the creasing roller, avoiding the problem of the rubber roller being squeezed and worn in the same position for a long time, which will produce annular grooves. It effectively avoids wear defects affecting the cardboard creasing operation, ensures the forming quality of the corrugated carton linerboard, extends the service life of the rubber roller, and ensures that the equipment can continuously and stably complete standardized creasing processing. 2. By setting up an opening and closing section, when the equipment performs cardboard creasing operations, the opening and closing section drives the creasing roller to move down and adhere to the glue roller. In conjunction with the transmission structure of the moving section, the cardboard is conveyed to complete the cardboard extrusion and creasing forming operation. When the equipment needs to adjust the pressure position of the glue roller, the opening and closing section drives the creasing roller to move up and away from the glue roller, releasing the adhesion and compression state between the two. After the glue roller position is adjusted, the creasing roller is driven down again to adhere to the glue roller, restoring the creasing operation state. It can cooperate with the moving section to complete the switching operation of the glue roller contact position. At the same time, it can adapt to the opening and closing requirements of cardboard creasing operations, provide sufficient operating space for glue roller position adjustment, ensure the smooth operation of creasing position adjustment, and stably complete the cardboard extrusion and creasing forming process.

[0019] It should be noted that the control of motor 1 211, electric telescopic pole 1 219, motor 2 224, electric telescopic pole 2 314 and motor 3 321 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.
[0020] A specific application of this embodiment is as follows: When in use, the cardboard can be placed on the workbench 102, and then the motor 224 can be started, so that its output shaft drives the lower rotating shaft 221 to rotate. When the lower rotating shaft 221 rotates, under the action of the two gears 223, it drives the two transmission rollers 222 to rotate through the two rotating shafts 221. Then the cardboard can be pushed into the machine box 101. Under the action of the two transmission rollers 222, the cardboard will be driven backward. During this process, the motor 321 and the motor 211 can be started at the same time, so that they drive the rotating shaft 322 and the rotating shaft 212 to rotate respectively. At this time, the rotating shaft 322 will drive the creasing roller 324 to rotate through the pressing roller 323, while the rotating shaft 212 will drive the glue roller 215 to rotate through the cross block 214. The cardboard will be creasing and shaped by the creasing roller 324 and the glue roller 215. After processing a batch of goods, motor 1 211, motor 224 and motor 321 can be turned off, and electric telescopic rod 2 314 can be started. Its output end drives the two brackets 312 to slide in the two slide grooves 311 through the connecting plate 313. This drives the pressure roller 324 away from the rubber roller 215 through the rotating shaft 322 and the extrusion roller 323. Then, electric telescopic rod 1 219 can be started, and its output end drives the rotating block 217 to move through the C-shaped block 218. When the rotating block 217 moves, it will drive the rubber roller 215 to slide on the cross block 214 through the rotating block 1 216. Since the rotating block 1 216 and the rotating block 217 are rotatably connected, the normal connection between the rotating block 217 and the rotating block 1 216 will not be affected when the rubber roller 215 rotates. After the rubber roller 215 moves, the electric telescopic rod 219 can be closed and the electric telescopic rod 314 can be activated, so that it moves downward through the connecting plate 313 and the bracket 312. At this time, the rotating shaft 322 will drive the pressure roller 324 to move downward through the extrusion roller 323, thereby extruding the rubber roller 215. The moved rubber roller 215 will change the extrusion position of the pressure roller 324.
