[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 As shown, an embodiment of the present invention proposes a cutting device for a paper-plastic composite bag, which includes a shell 1 with a support arm 3 on the top; a pressing device, which is arranged on the support arm 3 and is used to press the paper-plastic composite bag body 100; a shearing device, including a movable seat 4 slidably set on the support arm 3 through a first screw 303 and a cutter 2 slidably set on the movable seat 4 through a driving source 401, the first screw 303 is used to drive the movable seat 4 to reciprocate, and the cutter 2 is used to cut the paper-plastic composite bag body 100; a limiting device, which is arranged on one side of the shell 1 and is used to abut the paper-plastic composite bag body 100.

[0022] The detailed working process of this embodiment is as follows: the cutter 2 is fixedly arranged at the output end of the driving source 401, and the driving source 401 drives the cutter 2 to move downward to cut the paper-plastic composite bag.

[0023] The paper-plastic composite bag body 100 is cut by a cutter 2 that is adjustable within a certain range and is provided on the support arm 3, thereby meeting the cutting requirements of paper-plastic composite bag bodies 100 of different specifications and different sizes. At the same time, a plurality of groups of paper-plastic composite bag bodies 100 to be cut are fixed by a pressing device and a limiting device, thereby preventing the cutter 2 from being displaced during the cutting process and affecting the cutting accuracy.

[0024] The driving source 401 in this embodiment is a cylinder. In other embodiments, a suitable driving device can be selected according to actual conditions.

[0025] like Figure 3 As shown, the clamping device includes two first support arms 602 and two second support arms 604 and a pressure plate 6, and a connecting seat 605 is provided on the support arm 3 and the pressure plate 6, wherein the two first support arms 602 and the two second support arms 604 are hinged at one end to the corresponding connecting seat 605 respectively, and the other end of each first support arm 602 and each second support arm 604 is hinged to the connecting block 603, and the two connecting blocks 603 are threaded with a bidirectional stud 606.

[0026] The detailed working process of this embodiment is as follows: one end of the two first support arms 602 is hinged to the connecting seat 605 on the support arm 3, and one end of the two second support arms 604 is hinged to the connecting seat 605 on the pressing plate 6. The two first support arms 602 and the two second support arms 604 are hinged via two connecting blocks 603. By rotating the two-way stud 606, the two connecting blocks 603 are moved away from or towards each other, thereby changing the distance between the pressing plate 6 and the support arm 3. When the two connecting blocks 603 move away from each other, the pressing plate 6 moves closer to the support arm 3. Conversely, the pressing plate 6 moves away from the support arm 3. This controls the pressing plate 6 to compress and secure the paper-plastic composite bag, preventing multiple groups of paper-plastic composite bags from shifting during cutting.

[0027] like Figure 2 As shown, a travel groove 301 is provided on the support arm 3, the movable seat 4 is slidably arranged in the travel groove 301, the first screw 303 is rotatably arranged on the support arm 3 and is located in the travel groove 301, and the first screw 303 is threadedly connected to the movable seat 4.

[0028] The detailed working process of this embodiment is: rotating the first screw 303 can drive the movable seat 4 to translate in the travel groove 301, thereby changing the position of the cutter 2. The first screw 303 can be rotated for adjustment according to needs. After adjusting to the appropriate position, the drive source 401 is controlled to drive the cutter 2 to perform cutting.

[0029] like Figure 2 As shown, a limit rod 201 is provided on the cutter 2 , and the limit rod 201 is passed through the movable seat 4 .

[0030] The detailed working process of this embodiment is as follows: the function of the limiting rod 201 is to limit the cutter 2, thereby ensuring the position of the cutter 2 during the cutting process and preventing the cutter 2 from being displaced after being subjected to force.

[0031] like Figure 2 As shown, the limiting device includes a second screw rod 501 rotatably provided on the housing 1 and an adjusting plate 5 rotatably provided on one end of the second screw rod 501 close to the pressing plate 6 .

[0032] The detailed working process of this embodiment is as follows: the adjusting plate 5 is used to limit the position of the paper-plastic composite bag to prevent multiple groups of overlapping paper-plastic composite bags from sliding; the shell 1, the adjusting plate 5 and the pressing plate 6 cooperate with each other to limit and fix the paper-plastic composite bag, limit the degree of freedom of the paper-plastic composite bag, and prevent multiple groups of paper-plastic composite bags from displacement during cutting, which affects the cutting effect; at the same time, the adjusting plate 5 can be adjusted by the second screw 501 so that the adjusting plate 5 can abut against paper-plastic composite bags of different specifications.

[0033] like Figure 2 As shown, scale lines 302 are provided on both the support arm 3 and the housing 1 .

[0034] The detailed working process of this embodiment is as follows: the scale lines 302 on the shell 1 are used to measure the length or width of the material to be cut to ensure the accuracy of cutting, while the scale lines 302 on the support arm 3 are used to adjust the position of the cutter 2 to improve the accuracy of cutting.

[0035] like Figure 2 As shown, a rubber pad 601 is provided on the pressing plate 6 .

[0036] The detailed working process of this embodiment is to prevent the pressing plate 6 from directly contacting the paper-plastic composite bag and causing damage to the paper-plastic composite bag.

[0037] like Figure 1 As shown, support feet 102 are provided at the four corners of the bottom of the housing 1 .

[0038] The detailed working process of this embodiment is as follows: the function of the supporting legs 102 is to support the housing 1 .

[0039] like Figure 3 As shown, each leg 102 is provided with an anti-slip pad 103 .

[0040] The detailed working process of this embodiment is as follows: the function of the anti-slip pad 103 is to prevent the housing 1 from being displaced during the working process.

[0041] The implementation principle of the embodiment of the present application is: first, multiple groups of paper-plastic composite bags are stacked on the shell 1, and then the second screw 501 is rotated to make the adjustment plate 5 close to the paper-plastic composite bag and abut against it. After the multiple groups of stacked paper-plastic composite bags are aligned, the two-way stud 606 is rotated to drive the pressure plate 6 to approach the paper-plastic composite bag and press it tightly, and then the first screw 303 is rotated to adjust the position of the cutter 2. After adjusting to the appropriate position, the drive source 401 is controlled to drive the cutter 2 to perform cutting.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
