Description

Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to a paper feeding structure of a paper cutter. Background Art

[0002] Paper cutters are traditional products used to handle the paper cutting needs in the later stages of printing. From mechanical paper cutters to tape-controlled paper cutters, and then to microcomputer program control, color display, full-image operation-guided visual processing, and computer-aided cutting external programming and editing of production data cutting systems, production preparation time is shorter, cutting accuracy is higher, labor intensity is lower, and operation is safer; Patent No. CN202121448423.1 discloses a vertical cardboard paper cutter paper cutting mechanism. When the paper cutter cuts paper, the engine on the cutting device will start and push the blade on the link block. The engine pushes the fixed rod to drive the fixed block to move vertically, so that the fixed block squeezes the airbag, and the air inside is compressed by the squeezing of the airbag to discharge it through the high-density grid in the exhaust port, blowing the airflow on the blade and cleaning the paper debris; However, when using a paper cutter to cut paper, the staff generally manually pushes the stacked paper to move it to the bottom of the cutter inside the paper cutter for cutting, which is not convenient enough to operate. Therefore, we propose a paper feeding structure for a paper cutter. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a paper feeding structure for a paper cutter.

[0004] The technical solution adopted by the utility model to solve the technical problem is a paper feed structure of a paper cutter, comprising a body, a groove is provided on the top surface of the body, and a roller is rotatably installed in the groove, and there are two groups of rollers, a reducer is installed on the outer wall surface of the body for transmission connection with the rollers, and a servo motor is installed at the power input end of the reducer, a conveyor belt located on the inner side of the groove is installed between the two groups of rollers, and an anti-cutting cloth layer is bonded to the outer periphery of the conveyor belt, and a support plate located between the two groups of rollers is installed in the groove;

[0005] The outer wall of the body is equipped with a support, and a sliding hole is opened in the support, and there are two groups of sliding holes. A slider is slidably installed in the sliding hole, and a side of the slider located in the sliding hole is equipped with a vertical rod, the inner wall of the sliding hole is equipped with a vertical cylinder plugged into the vertical rod, and a conductive sheet is installed in the vertical cylinder, a U-shaped electric sheet located on the inner periphery of the vertical rod is installed between the two groups of vertical rods, the slider is equipped with a disk seat on the side opposite to the sliding hole, and a spring for pushing the slider to move is installed between the two groups of disk seats.

[0006] By adopting the above technical solution, when using a paper cutter to cut paper, it is convenient to place the paper stack on the conveyor belt on the surface of the machine body. Subsequently, the servo motor outside the machine body is operated. The operation of the servo motor facilitates the rotation of the roller in the groove driven by the reducer, enabling the two rollers to drive the conveyor belt to rotate accordingly and convey the paper stack to the lower part of the cutter inside the machine body, facilitating subsequent cutting. Moreover, the automatic conveying method is more convenient. At the same time, the anti-cut cloth layer on the surface of the conveyor belt is conducive to reducing the impact caused by the cutter of the paper cutter, enabling the conveyor belt to convey the paper stack more stably. Meanwhile, both the cut paper stack and the remaining debris after cutting can be removed from below the cutter along with the displacement of the conveyor belt, facilitating personnel to handle them;

[0007] When the staff places the paper stack to be cut on the surface of the conveyor belt, the staff can kick the slider on the outer wall surface of the machine body near the bottom support with their toes, causing the slider to retract into the slide hole inside the support under pressure. At the same time, the slider conveniently drives the vertical rod to penetrate into the vertical cylinder, and the U-shaped electric sheet inside the vertical rod can be in mutual contact with the conductive sheet in the vertical cylinder, thus forming a series connection and enabling the circuit to conduct. At this time, the servo motor operates, and the two sliders on the surface of the support respectively represent forward and backward, facilitating the control of the forward and reverse rotation of the servo motor, enabling the paper stack to move forward or backward along with the conveyor belt. At the same time, when the slider is not under pressure, the spring will push the slider back, causing the slider to drive the vertical rod to slide relative to the vertical cylinder, and the U-shaped electric sheet to separate from the conductive sheet, thus forming an open circuit. At this time, the servo motor will stop operating, and pressing the slider with the foot will cause the staff to support the outer wall of the machine table on the surface of the machine body with both hands, facilitating the reduction of the situation where the staff reaches their hands under the cutter inside the machine body and improving the safety of the staff during operation.

[0008] Specifically, a shock-absorbing cylinder located inside the spring is assembled between the two disc seats.

[0009] By adopting the above technical solution, the shock-absorbing cylinder is convenient to be used in cooperation with the spring, enabling the spring to operate more stably.

[0010] Specifically, a corrugated rubber tube located outside the spring is assembled between the two disc seats.

[0011] By adopting the above technical solution, the corrugated rubber tube can expand and contract, facilitating the protection of the operation of the spring and the shock-absorbing cylinder.

[0012] Specifically, a housing located outside the servo motor is assembled on the outer wall surface of the machine body.

[0013] By adopting the above technical solution, the housing is convenient for protecting the operation of the servo motor.

[0014] Specifically, one end of the slider located inside the sliding hole is integrally formed with a sliding frame adapted to the sliding hole.

[0015] By adopting the above technical solution, the sliding frame is convenient for improving the stability of the slider when sliding in the sliding hole.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. Through the design of the groove, roller, reducer, servo motor, conveyor belt, anti-cut cloth layer and support plate in the technical solution of the present application, when using a paper cutter to cut paper, it is convenient to stack the paper on the conveyor belt on the surface of the machine body. Subsequently, the servo motor outside the machine body operates. The operation of the servo motor is convenient for driving the roller in the groove to rotate through the operation of the reducer, so that the two rollers can drive the conveyor belt to rotate accordingly and convey the paper stack to the lower part of the cutter inside the machine body, which is convenient for subsequent cutting. Moreover, the automatic conveying method is more convenient. At the same time, the anti-cut cloth layer on the surface of the conveyor belt is convenient for reducing the influence caused by the cutter of the paper cutter on it, so that the conveyor belt can convey the paper stack more stably. At the same time, the paper stack and the remaining debris after cutting can both move out from under the cutter along with the displacement of the conveyor belt, which is convenient for personnel to handle.

[0018] 2. Through the design of the support, sliding hole, slider, vertical rod, vertical cylinder, conductive sheet, U-shaped electric sheet, disc seat and spring in the technical solution of the present application, when the staff places the paper stack to be cut on the surface of the conveyor belt, the staff can use the toe to kick the slider on the support near the bottom side on the outer wall of the machine body, so that the slider retracts into the sliding hole inside the support under pressure. At the same time, the slider is convenient for driving the vertical rod to penetrate into the vertical cylinder, and the U-shaped electric sheet inside the vertical rod can be in contact with the conductive sheet in the vertical cylinder, thus forming a series connection and making the circuit flow. At this time, the servo motor operates, and the two sliders on the surface of the support respectively represent forward and backward, which is convenient for controlling the forward and reverse rotation of the servo motor, so that the paper stack can move forward or backward along with the conveyor belt. At the same time, when the slider is not under pressure, the spring will push the slider back, so that the slider drives the vertical rod to slide relative to the vertical cylinder, and the U-shaped electric sheet and the conductive sheet are separated from each other, thus forming an open circuit. At this time, the servo motor will stop operating, and pressing the slider with the foot will make the staff hold the outer wall of the machine table on the surface of the machine body with both hands, which is convenient for reducing the situation that the staff puts both hands under the cutter inside the machine body and improving the safety of the staff during operation.

Specific embodiments

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please refer to Figures 1-3 , an embodiment of the present utility model provides a technical solution: a paper feeding structure of a paper cutter, including a machine body 1, a groove 2 is opened on the top surface of the machine body 1, and two rollers 3 are rotatably installed in the groove 2, and a speed reducer 4 is assembled on the outer wall surface of the machine body 1 and is drivingly connected to the roller 3, and a servo motor 5 is assembled at the power input end of the speed reducer 4. A conveyor belt 6 is assembled between the two rollers 3 and is located inside the groove 2, and an anti-cut cloth layer 7 is adhered to the outer circumference of the conveyor belt 6. A support plate 8 is assembled in the groove 2 and is located between the two rollers 3; a support 9 is assembled on the outer wall of the machine body 1, and two sliding holes 10 are opened in the support 9. Sliders 11 are slidably installed in the sliding holes 10, and a vertical rod 12 is assembled on one surface of the slider 11 located in the sliding hole 10. A vertical cylinder 13 is assembled on the inner wall of the sliding hole 10 and is inserted and connected to the vertical rod 12, and a conductive sheet 14 is assembled in the vertical cylinder 13. A U-shaped electric sheet 15 is assembled between the two vertical rods 12 and is located inside the vertical rod 12. Disc seats 16 are assembled on the opposite surfaces of the slider 11 and the sliding hole 10, and a spring 17 for pushing the slider 11 to displace is assembled between the two disc seats 16.

[0026] During use, when using a paper cutter to cut paper, it is convenient to place the paper stack on the conveyor belt 6 on the surface of the machine body 1. Subsequently, the servo motor 5 outside the machine body 1 is operated. The operation of the servo motor 5 facilitates the operation of the reducer 4 to drive the roller 3 in the groove 2 to rotate, enabling the two rollers 3 to drive the conveyor belt 6 to rotate accordingly and convey the paper stack to below the cutter inside the machine body 1, facilitating subsequent cutting. Moreover, the automatic conveying method is more convenient. At the same time, the anti-cut cloth layer 7 on the surface of the conveyor belt 6 is conducive to reducing the impact caused by the cutter of the paper cutter, enabling the conveyor belt 6 to convey the paper stack more stably. Meanwhile, both the cut paper stack and the remaining debris can be removed from below the cutter with the displacement of the conveyor belt 6, facilitating personnel to handle them;

[0027] When the staff places the paper stack to be cut on the surface of the conveyor belt 6, the staff can kick the slider 11 on the outer wall surface of the machine body 1 near the bottom support 9 with their toes, causing the slider 11 to retract into the slide hole 10 inside the support 9 under pressure. Meanwhile, the slider 11 facilitates driving the vertical rod 12 to penetrate into the vertical cylinder 13, and the U-shaped electric sheet 15 inside the vertical rod 12 can be in mutual contact with the conductive sheet 14 in the vertical cylinder 13, thereby forming a series connection and enabling the circuit to conduct. At this time, the servo motor 5 operates, and the two sliders 11 on the surface of the support 9 respectively represent forward and backward, facilitating the control of the forward and reverse rotation of the servo motor 5, enabling the paper stack to move forward or backward with the conveyor belt 6. At the same time, when the slider 11 is not under pressure, the spring 17 will push the slider 11 backward, causing the slider 11 to drive the vertical rod 12 to slide relative to the vertical cylinder 13, and separating the U-shaped electric sheet 15 from the conductive sheet 14, thereby forming an open circuit. At this time, the servo motor 5 will stop operating, and pressing the slider 11 with the foot will cause the staff to support their hands on the outer wall of the machine table on the surface of the machine body 1, facilitating reducing the situation where the staff's hands reach below the cutter inside the machine body 1 and improving the safety of the staff during operation.

[0028] As Figure 3 shown, a shock-absorbing cylinder 18 located inside the spring 17 is assembled between the two disc seats 16.

[0029] During use, the shock-absorbing cylinder 18 is convenient to be used in cooperation with the spring 17, enabling the spring 17 to operate more stably.

[0030] As Figure 3 shown, a corrugated rubber tube 19 located outside the spring 17 is assembled between the two disc seats 16.

[0031] During use, the corrugated rubber tube 19 can expand and contract, facilitating the protection of the operation of the spring 17 and the shock-absorbing cylinder 18.

[0032] As Figure 1As shown, an outer shell 21 located on the outer wall surface of the body 1 is assembled around the outer periphery of the servo motor 5.

[0033] During use, the outer shell 21 facilitates the protection of the operation of the servo motor 5.

[0034] As Figure 3 shown, one end of the slider 11 located within the sliding hole 10 is integrally formed with a sliding frame 20 adapted to the sliding hole 10.

[0035] During use, the sliding frame 20 facilitates improving the stability of the slider 11 when sliding within the sliding hole 10.

[0036] Working principle and usage process of the utility model: When in use, first install the corresponding structural components in appropriate positions. When using a paper cutter to cut paper, it is convenient to stack the paper on the conveyor belt 6 on the surface of the machine body 1. Subsequently, operate the servo motor 5 outside the machine body 1. The operation of the servo motor 5 facilitates the operation of the reducer 4 to drive the roller 3 in the groove 2 to rotate, so that the two rollers 3 can drive the conveyor belt 6 to rotate accordingly and convey the paper stack to the lower part of the cutter inside the machine body 1, facilitating subsequent cutting. Moreover, the automatic conveying method is more convenient. At the same time, the anti-cut cloth layer 7 on the surface of the conveyor belt 6 is convenient for reducing the impact caused by the cutter of the paper cutter, enabling the conveyor belt 6 to convey the paper stack more stably. At the same time, the cut paper and the remaining debris after cutting can both move out from under the cutter along with the displacement of the conveyor belt 6, facilitating personnel to process them. At the same time, when the staff places the paper stack to be cut on the surface of the conveyor belt 6, the staff can kick the slider 11 on the outer wall surface of the machine body 1 near the bottom support 9 with their toes, so that the slider 11 retracts into the slide hole 10 inside the support 9 under pressure. At the same time, the slider 11 is convenient for driving the vertical rod 12 to penetrate into the vertical cylinder 13, and the U-shaped electric sheet 15 inside the vertical rod 12 can be in mutual contact with the conductive sheet 14 in the vertical cylinder 13, thus forming a series connection and enabling the circuit to conduct. At this time, the servo motor 5 operates, and the two sliders 11 on the surface of the support 9 respectively represent forward and backward, facilitating the control of the forward and reverse rotation of the servo motor 5, so that the paper stack can move forward or backward along with the conveyor belt 6. At the same time, when the slider 11 is not under pressure, the spring 17 will push the slider 11 in the opposite direction, causing the slider 11 to drive the vertical rod 12 to slide relative to the vertical cylinder 13, and separating the U-shaped electric sheet 15 from the conductive sheet 14, thus forming an open circuit. At this time, the servo motor 5 will stop operating, and pressing the slider 11 with the foot will enable the staff to support the outer side wall of the machine table on the surface of the machine body 1 with both hands, facilitating the reduction of the situation where the staff's hands reach under the cutter inside the machine body 1, improving the safety of the staff during operation. At the same time, a support 9 can also be added to facilitate the control of the cutter inside the machine body 1, enabling the staff to support the side wall of the machine table with both hands and then use the foot to lift and press the slider 11 on the surface of the support 9 to make the cutter operate and cut the paper stack, which is safer to operate.
