[0004] Currently, when cutting paper, it is necessary to manually place the paper on the workbench, and then use an auxiliary pressing mechanism to clamp and flatten the paper. If a large number of papers need to be processed, manual loading not only increases the complexity of the operation and reduces production efficiency, but also has problems such as low positioning accuracy, dimensional deviation, and paper waste. In view of this, we propose a cutting device for paper product processing with a feeding structure. Utility Model Content

[0027] Currently, when cutting paper, it is necessary to manually place the paper on a workbench and then clamp and flatten the paper through an auxiliary pressing mechanism. If a large number of papers need to be processed, manual loading not only increases the complexity of the operation and reduces production efficiency, but also has problems such as low positioning accuracy, dimensional deviation, and paper waste.

[0028] See also Figure 1-Figure 4 As shown, the device includes a workbench 1, the bottom of the workbench 1 is fixedly connected to a support frame 11 for stably supporting it, a cutting robot arm 12 is installed on one side of the workbench 1, and a feeding component 2 for loading paper products to be cut is arranged inside the end of the workbench 1 away from the cutting robot arm 12, and a secondary limit component 3 is installed at the end of the workbench 1 away from the feeding component 2, and the secondary limit component 3 can center the paper products to be cut and assist in measurement.

[0029] It should be noted that the shearing head of the cutting robot arm 12 is the output end of the cutting robot arm 12, which moves on the surface of the workbench 1 and is used to cut the paper products that need to be cut.

[0030] The working principle of the cutting robot arm 12 is disclosed below: the working principle of the cutting robot arm 12 is well known to those skilled in the art. The mechanical structure of the cutting robot arm 12 is the basis for realizing its multi-degree-of-freedom movement. It is composed of multiple joints, connecting rods, etc., which move in coordination with drive systems such as motors and reducers to realize the degree-of-freedom movement of the robot arm. The control principle of the cutting robot arm 12 is the key to its ability to move accurately and perform tasks. The robot arm's state and environmental information are detected by sensors, and the robot arm's motion trajectory and control instructions are calculated, so that the robot arm can accurately perform cutting tasks. The cutting execution part of the cutting robot arm 12 usually includes a cutting blade and a cutting power device. The cutting blade is designed and manufactured according to the cutting requirements to ensure the accuracy and efficiency of cutting. The cutting power device provides power through a motor or air pressure to drive the cutting blade to perform cutting operations.

[0031] First, the specific structure of the feeding assembly 2 is disclosed. The feeding assembly 2 includes a feeding roller group 21 installed inside the side of the workbench 1 away from the cutting robot arm 12. The feeding roller group 21 is driven by a starting member 24. Two inclined guide groups 22 are installed on the upper end of the side of the feeding roller group 21 close to the opening of the workbench 1. The side ends of the two inclined guide groups 22 are provided with positioning groups 23. The two inclined guide groups 22 are both composed of an inclined guide control cylinder 221 and an inclined guide plate 222. The inclined guide plate 222 is located at the end of the piston rod of the inclined guide control cylinder 221. The two positioning groups 23 are both composed of a positioning control cylinder 231 and a positioning cross plate 232. The positioning cross plate 232 is fixedly connected to the end of the piston rod of the positioning control cylinder 231. A positioning bin 25 for auxiliary positioning of the paper product feeding position is formed between the two positioning cross plates 232. The side of the inclined guide control cylinder 221 and the positioning control cylinder 231 away from the piston rod is fixedly installed on the inner wall of the workbench 1. It can be seen that before cutting the same batch of paper products, the oblique guide control cylinder 221 and the positioning control cylinder 231 can be controlled and adjusted first, so that the spacing between the positioning bin 25 and the two oblique guide plates 222 is slightly larger than the width of the current batch of paper products, and then the starter 24 is turned on to operate, so that the feed roller group 21 formed by a plurality of feed rollers rotates inside one side of the workbench 1, and then the paper products to be processed are placed one by one on the surface of the feed roller group 21. With the start of the feed roller group 21, the paper products can be driven to move toward the cutting robot arm 12. While the paper products are moving, the two oblique guide plates 222 can guide the paper products to move, and the positioning bin 25 formed by the two positioning cross plates 232 can control the end conveying position of the paper products. There is no obstruction on the top of the feed roller group 21, which is convenient for the staff to adjust the position of the paper products in time when the paper product transportation is stuck.

[0032] It should be noted that the starter 24 is formed by a plurality of gears and chains meshing with each other, and the plurality of gears are respectively connected to the ends of the feed rollers. The gears can be driven by a motor to allow the plurality of feed rollers to rotate simultaneously in the same direction, thereby achieving the effect of conveying paper products.

[0033] Among them, the oblique guide control cylinder 221 and the positioning control cylinder 231 respectively adjust the positions of the oblique guide plate 222 and the positioning cross plate 232 based on pneumatic transmission. This is a prior art and will not be elaborated here.

[0034] Secondly, the specific structure of the secondary limit assembly 3 is disclosed. The secondary limit assembly 3 includes an adjustment groove 31 opened inside the workbench 1 on the side close to the cutting robot arm 12. A sliding hole 35 is opened on the top of the adjustment groove 31. A bidirectional screw rod 32 is rotated inside the adjustment groove 31. Two slide plates 34 are movably installed on the surface of the bidirectional screw rod 32, and the two slide plates 34 are symmetrically installed. The other ends of the two slide plates 34 extend out of the surface of the workbench 1 and are fixedly connected to the bottom of the positioning plate 33. A cutting bin 36 is formed between the two positioning plates 33. When the paper product is conveyed to the bottom of the cutting robot arm 12, the bidirectional screw rod 32 is rotated (the bidirectional screw rod 32 is preferably started by a motor). Through the rotation of the bidirectional screw rod 32, the two slide plates 34 symmetrically sleeved on its surface can be driven to slide in opposite directions, thereby driving the two positioning plates 33 to clamp the paper product. On the one hand, the fixing effect during the paper product cutting process is achieved. On the other hand, the paper product is clamped between the two positioning plates 33. The cutting size of the paper product can be observed through the scale on the surface of the positioning plate 33. If a cutting deviation occurs, the cutting robot arm 12 is controlled in time, thereby reducing the waste of paper products.

[0035] Since the paper products need to be transported to the bottom of the cutting robot arm 12 by the feeding roller group 21 for cutting operation, in order to further improve the conveying effect of the paper products and reduce the reduction of cutting efficiency due to too slow conveying efficiency, the two positioning horizontal plates 232 are provided with inner grooves 4 on one side close to the positioning bin 25, and the inner grooves 4 are movably connected with auxiliary pulley groups 41 for assisting the paper product transmission. The auxiliary pulley group 41 is installed inside the inner groove 4 and connected to the starting structure (not shown in the figure), driving the auxiliary pulley group 41 and the feeding roller group 21 to rotate in the same direction. If the paper products move close to the inner wall of the positioning bin 25, the rotating auxiliary pulley group 41 can assist the paper products in conveying, thereby reducing the reduction of conveying efficiency due to the paper products touching the inner wall of the positioning bin 25.

[0036] It is worth mentioning that the starting structure connected to the auxiliary pulley group 41 is composed of multiple gears and chains meshing, and the gears are driven by a motor to start, the purpose is to drive the auxiliary pulley group 41 to rotate on the surface of the positioning horizontal plate 232 to assist in the transmission of paper products.

[0037] In the process of cutting paper products, it is inevitable that paper scraps will splash. If the cut paper scraps enter the inside of the adjustment slot 31 from the slide hole 35, it will affect the rotation of the bidirectional screw 32 to a certain extent. Therefore, in order to reduce the paper scraps from splashing into the inside of the adjustment slot 31, an elastic clamping pad 5 is installed on the inner wall of the slide hole 35. Among them, the elastic clamping pad 5 is composed of two clamping pages, and the two clamping pages are respectively fixedly connected to the inner walls of both sides of the slide hole 35. Due to the elastic structure of the clamping page, the slide hole 35 can be auxiliary closed without affecting the sliding of the slide plate 34, thereby reducing the situation of paper scraps splashing into the inside of the adjustment slot 31. The clamping page is preferably made of rubber material.

[0038] In summary, the working principle of this scheme is as follows: before cutting the same batch of paper products, the inclined guide control cylinder 221 and the positioning control cylinder 231 can be controlled and adjusted first, so that the spacing between the positioning bin 25 and the two inclined guide plates 222 is slightly larger than the width of the current batch of paper products, and then the starter 24 is turned on to operate, so that the feed roller group 21 formed by a plurality of feed rollers rotates inside one side of the workbench 1, and then the paper products to be processed are placed one by one on the surface of the feed roller group 21. With the start of the feed roller group 21, the paper products can be driven to move toward the cutting robot arm 12. While the paper products are moving, the two inclined guide plates 222 can guide the paper products to move, and the positioning bin 25 formed by the two positioning cross plates 232 can control the terminal conveying position of the paper products. If the paper products move close to the inner wall of the positioning bin 25, the rotating auxiliary pulley group 41 can assist in conveying the paper products, thereby reducing the situation where the conveying efficiency is reduced due to the paper products touching the inner wall of the positioning bin 25.

[0039] When the paper product is conveyed to the bottom of the cutting robot arm 12, the bidirectional screw rod 32 is rotated. Through the rotation of the bidirectional screw rod 32, the two slide plates 34 symmetrically sleeved on its surface can be driven to slide in the opposite direction, thereby driving the two positioning plates 33 to clamp the paper product. On the one hand, the fixing effect in the paper product cutting process is achieved. On the other hand, the paper product is clamped between the two positioning plates 33. The cutting size of the paper product can be observed through the scale on the surface of the positioning plate 33. If there is a cutting deviation, the cutting robot arm 12 is controlled in time, thereby reducing the waste of paper products.
