For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0018] like Figure 1-Figure 2 This is the embodiment structure of the present application.

[0019] The adjustable cutter for a paper bag cutting device provided in this embodiment comprises a moving unit mounted on two side fixing plates 2, wherein the moving unit comprises a driving motor 1 mounted on one side fixing plate, a screw rod 3 connected to the output shaft of the driving motor 1, and a guide rod 5 arranged parallel to the screw rod 3 and connected to the fixing plates on both sides;

[0020] The screw rod 3 and the guide rod 5 pass through the plurality of cutter units 4 and are respectively threadedly connected and slidably connected. The driving motor drives the screw rod 3 to rotate, so that the cutter unit 4 moves on the screw rod 3 and the guide rod 5.

[0021] Each of the cutter units 4 includes a bearing block, a bearing 45 is provided in the bearing block, a nut block 46 is fixedly connected to the inner ring of the bearing 45, the screw rod 3 passes through the nut block 46 and is threadedly connected, a sliding cavity is provided on the nut block 46 at the upper end of the bearing, a sliding block 43 capable of moving left and right is provided in the sliding cavity, a connecting rod 41 sleeved with a first spring 42 is connected to the left end of the sliding block 43, the connecting rod 41 passes through the sliding cavity wall and is connected to one end of an L-shaped linkage rod 418, and the other end of the L-shaped linkage rod 418 is inserted into a socket provided on the nut block 46;

[0022] When the L-shaped linkage rod 418 is inserted into the jack, the positions of the bearing block and the nut block 46 are relatively fixed and will not move relative to each other. When the screw rod rotates, the bearing block moves, and the position of the cutter unit can be adjusted. When the L-shaped linkage rod 418 of the cutter unit is pulled out of the jack and rotated by a certain angle, when the positions of the insertion rod and the jack do not correspond, the bearing block and the nut block 46 can rotate relative to each other. When the screw rod rotates, the bearing block is driven to rotate synchronously, and the position of the cutter unit does not change. With this structure, the position adjustment of a single cutter unit can be realized.

[0023] The lower end of the bearing block is provided with a T-shaped hole (along the Figure 2 A T-shaped slider 412 is detachably connected to the T-shaped hole, and a cutter body 413 is connected to the lower end of the T-shaped slider 412. The cutter body 413 is fixed by a tightening member on the lower end surface of the bearing block.

[0024] The above structure enables the cutter body 413 to be quickly installed and disassembled.

[0025] When installation is required, the T-shaped slider 412 connected to the cutter body 413 is slid into the T-shaped hole accordingly, and then tightened with the tightening piece to complete the installation; when disassembling the cutter body, the locking piece is used to achieve it, and then the T-shaped slider is slid out of the T-shaped hole.

[0026] Preferably, a specific structure of a bearing block and a locking member is provided, wherein the bearing block comprises an upper bearing block 44 and a lower bearing block 411, the screw rod 3 passes through the upper bearing block 44, an upper fixed flange 49 is provided on the edge of the lower end surface of the upper bearing block 44, a spring mounting groove is provided in the middle part of the lower end surface, a second spring 47 is installed in the spring mounting groove, the upper end of the second spring 47 is connected to the top of the spring mounting groove, and the lower end thereof is connected to the upper end surface of the lower bearing block 411, a lower fixed flange 410 is provided on the edge of the upper end surface of the lower bearing block 411, and the upper fixed flange 49 and the lower fixed flange 410 are connected by a locking bolt 48.

[0027] This structure can be used to adjust the longitudinal position of the cutter body. When the position needs to be adjusted, the position of the cutter body can be adjusted by adjusting the position of the nut on the locking bolt 48. Tightening the nut will move it upward, and loosening the nut will move it downward. Due to the elastic force of the second spring, the tightness can meet the usage requirements.

[0028] Preferably, a specific structure of a tensioning member is provided, which comprises a locking block 415 mounted on the lower end surface of a lower bearing block 411, a rod sliding cavity is arranged in the locking block 415, the upper end of the rod sliding cavity is open and a through hole is arranged on the lower bearing block 411 corresponding to the upper end opening position, a third spring 414 is connected to the lower end of the rod sliding cavity, a tensioning rod 417 is connected to the upper end of the third spring 414, the upper end of the tensioning rod 417 extends from the upper end opening of the rod sliding cavity and passes through the through hole to be tensioned on the T-shaped slider 412, a sliding hole connected to the rod sliding cavity is arranged on the side wall of the locking block 415, a shifting block 416 is slidably connected in the sliding hole, and one inner end of the shifting block 416 is fixedly connected to the side wall of the tensioning rod 417.

[0029] With this structure, when the Y-shaped slider needs to be disassembled, the lever is pushed downward to make the upper end of the tightening rod leave the T-shaped slider, so that the T-shaped slider can be easily taken out.

[0030] In addition, scale lines are provided on the guide rod 5 to facilitate the position and distance adjustment of the cutter body.

[0031] It should be noted that the structures not described in detail in the present application are all based on known technologies.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate and explain the present invention, and are not intended to limit the present invention to the scope of the described embodiments. In addition, those skilled in the art can understand that the present invention is not limited to the above embodiments, and more variations and modifications can be made according to the teachings of the present invention, and these variations and modifications all fall within the scope of protection claimed by the present invention.
