Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0026] A cardboard length cutting and transverse creasing device is applied in a commodity packaging production line and installed on the production line frame. Specifically, the creasing and cutting device includes a cardboard platform 100, a creasing component 200, and a cutting component 300. The cardboard platform 100 supports the cardboard for creasing. The creasing component 200 is positioned above the cardboard platform 100 and is used to press the required creases onto the packaging cardboard to facilitate subsequent folding. The cutting component 300 is connected to the cardboard feeding station of the packaging production line. During use, the feeding station continuously feeds cardboard; after passing through the cutting component 300, the cardboard is conveyed to the cardboard platform 100. The creasing component 200 creasing the cardboard, and once the cardboard reaches the required length, the cutting component 300 performs the cutting action. The entire process is controlled by a control system, which allows for flexible adjustment of the distance between creases and the length of the cut cardboard.

[0027] The creasing assembly 200 includes a creasing roller 210, a first drive assembly 220, and a first adjustment assembly 230. To improve working efficiency, the creasing assembly 200 can be provided in several groups; for example, two adjacent groups of creasing assemblies can be provided. The creasing roller 210 is arranged perpendicular to the paperboard feeding direction. The first drive assembly 220 drives the creasing roller 210 to rotate. The first adjustment assembly 230 is disposed between the creasing roller 210 and the first drive assembly 220 to adjust the distance between the creasing roller 210 and the paperboard platform 100, thereby adjusting the pressure of the creasing roller 210 on the paperboard.

[0028] The creasing roller 210 includes a roller body 211, and a creasing blade 212 protruding from the outer circumferential surface of the roller body 211 is arranged along the axial direction of the roller body 211. Specifically, the cylindrical roller body 211 has a notch along its axial direction, and the creasing blade 212 is a long, flat piece that is detachably and fixedly installed at the notch, with its blade protruding from the outer circumferential surface of the roller body 211. The first drive assembly 220 drives the creasing roller 210 to rotate, and each time the creasing blade 212 contacts the paperboard, it can press a crease on the surface of the paperboard. It can be seen that the distance between the creasing blade 212 and the paperboard is particularly important, so a first adjustment assembly 230 is provided to adjust the distance between the creasing roller 210 and the paperboard platform 100. When multiple sets of creasing assemblies 200 are provided, each creasing roller 210 is driven by its independent first drive assembly 220. This design allows the rotational speed of each creasing roller 210 to be independently adjustable.

[0029] The first drive assembly 220 is a drive motor, and the output end of the drive motor is connected to the roller 211. This design changes the lower shaft transmission method using gears in the prior art, thereby avoiding the paperboard rubbing phenomenon caused by gear backlash during gear transmission, and also avoiding paper jams caused by the transition gap between the transition plate and the lower shaft.

[0030] The first adjustment component 230 includes a lifting plate 231, a lifting rail 232, and a lifting frame 233. The lifting rail 232 is disposed on both sides of the lifting plate 231 and is fixedly disposed on the lifting frame 233. Thus, the lifting plate 231 can slide up and down along the lifting rail 232 on the lifting frame 233. The first drive component 220 and the roller body 211 are respectively disposed on both sides of the lifting plate 231 and move up and down accordingly. This design allows for very convenient adjustment of the distance between the creasing roller 210 and the cardboard platform 100. In order to adjust the height of the lifting plate 231 more flexibly and to prevent damage to the motor when paper jams occur, in one embodiment, the upper and lower ends of the lifting plate 231 are connected to the lifting frame 233 by spring 1 234 and spring 235 respectively. When paper jams occur, the thickness of the cardboard often increases. This design allows the distance between the creasing roller 210 and the cardboard platform 100 to be automatically adjusted by the springs in the event of a paper jam. That is, the lifting plate 231 can be automatically finely adjusted upward to prevent the motor from being damaged by excessive force. Furthermore, a crossbeam 236 is provided at the top of the lifting frame 233, and a star-shaped screw 237 is screwed onto the crossbeam 236. One end of the spring 234 is connected to the upper end of the lifting plate 231, and the other end is not directly connected to the lifting frame 233, but is connected to the lower end of the star-shaped screw 237. This design allows for convenient adjustment of the height of the lifting plate 231. For example, when it is necessary to increase the pressure, the star-shaped screw 237 can be turned downwards to move the lifting plate 231 downwards.

[0031] The cutting assembly 300 includes a roller cutter assembly 310, a second drive assembly 320, a cutting frame 330, and a second adjustment assembly 340. The roller cutter assembly 310 is connected to the second drive assembly 320 via the cutting frame 330. The second drive assembly 320 can drive the roller cutter assembly 310 to reciprocate along a direction perpendicular to the paperboard feeding direction. The second adjustment assembly 340 is disposed between the roller cutter assembly 310 and the cutting frame 330 for adjusting the height of the roller cutter assembly 310.

[0032] The second drive assembly 320 includes a drive wheel 321 and a drive belt 322. The drive wheel 321 includes a driving wheel and a driven wheel disposed at both ends of the drive belt 322. The driving wheel is driven by a motor. The motor drives the driving wheel to rotate in both directions, thereby causing the drive belt 322 to rotate in both directions in a circular motion. The roller cutter assembly 310 moves synchronously with the drive belt 322 through the cutting frame 330. Specifically, the upper end of the cutting frame 330 is fixedly connected to the drive belt 322, and the lower end is connected to the roller cutter assembly 310 through the second adjusting assembly 340. The cutting frame 330 moves along the slide rail 331 under the drive of the drive belt 322.

[0033] The second adjustment assembly 340 includes a mounting plate 341, an adjustment seat 342, and a screw 343 for adjusting the distance between the mounting plate 341 and the adjustment seat 342. The adjustment seat 342 is fixedly mounted on the cutting frame 330, and the roller cutter assembly 310 is mounted on the mounting plate 341 and moves up and down accordingly. Specifically, the screw 343 is screwed to the adjustment seat 342, and the lower end of the screw 343 is fixedly connected to the mounting plate 341. In use, turning the screw 343 can adjust the height of the mounting plate 341, thereby adjusting the height of the roller cutter assembly 310, that is, adjusting the distance between the roller cutter assembly 310 and the cardboard.

[0034] The roller cutter assembly 310 includes a coaxially arranged roller cutter 311 and a toothed roller cutter 312. The roller cutter 311 is a disc-shaped blade used for cutting cardboard. The toothed roller cutter 312 is also disc-shaped and has teeth evenly arranged along its circumference. It is used to cut serrated marks on the cardboard, facilitating subsequent folding of the carton and tearing during unpacking. The roller cutter assembly 310 also includes a rolling mark cutter 313, which is in the same plane as the toothed roller cutter 312, so that the rolling marks of the two are aligned.
