A guide belt cutting device

Abstract

This utility model discloses a guide belt cutting device, belonging to the field of guide belt cutting technology. The paper cutting component is located to the side of the paper clamping component, and is closer to the paper output slot outside the printer body than the paper clamping component. In this manner, starting the first motor drives the first gear to rotate, which in turn drives the second gear to rotate in the opposite direction. The rotation of the first and second gears respectively drives the first and second movable blocks to perform circular motion. The two sets of cutters fixed at the ends of the first and second movable blocks will touch at a certain time, at which point the paper between the two sets of cutters can be cut. Since the first and second gears are of the same size, the contact time between the two sets of cutters is fixed each time, thereby achieving uniform cutting of the paper and resulting in a flat and aesthetically pleasing cut on the receipt.

Technical Field

[0001] This utility model relates to the field of guide belt cutting technology, and specifically to a guide belt cutting device. Background Technology

[0002] A printer is a computer output device used to print the results of computer processing onto relevant media.

[0003] In the existing technology, printers are a common type of machine in daily life, often used in catering or self-service. They use specific technologies to convert data such as text and images into physical outputs, with common media including paper and labels.

[0004] However, in the catering industry, when using a printer to print receipts for customers, the printed receipts need to be manually torn from the printing paper, resulting in messy and unsightly tear edges, and even the possibility of tearing the receipts.

[0005] Based on this, the present invention designs a guide belt cutting device to solve the above problems. Utility Model Content

The surface of the support plate is equipped with a paper clamping component that can prevent the printing paper from loosening. The paper cutting component is located to the side of the paper clamping component, and the paper cutting component is closer to the paper output slot outside the printer body than the paper clamping component. The paper tensioning assembly includes a tensioning component and a driving component. Both the tensioning component and the driving component are connected to the tray. The driving component is located to the side of the tensioning component and is closer to the paper output slot outside the printer body than the tensioning component.

[0008] Furthermore, the printing paper cutting assembly includes a first movable block, a first gear, a second movable block, a second gear, a support platform, a first motor, an annular block, a guide rod, and a cutter. The support platform is fixedly mounted on the back surface of the support plate. The first motor is fixedly mounted on the upper end of the support platform. The first gear and the second gear are rotatably mounted on the back surface of the support plate. The first gear and the second gear are meshed together. The first gear and the second gear are the same size. The output end of the first motor is fixedly connected to the surface of the first gear. An annular block and a guide rod are fixedly mounted on the surfaces of both the first gear and the second gear. The first movable block and the second movable block are respectively fixed to the ends of the guide rods on the surfaces of the first gear and the second gear. A cutter is fixed to the ends of both the first movable block and the second movable block. The two sets of cutters correspond to each other.

[0009] Furthermore, an annular groove is formed on the back surface of the support plate, and the inner wall of the annular groove is in rotatable connection with the outer surface of the annular block.

[0010] Furthermore, the tensioning assembly includes a weight, a support frame, a steering roller, a movable sleeve, and a sleeve shaft. The support platform has a notch on its right side, and the two sets of steering rollers are respectively rotatably mounted at both ends of the notch on the right side of the support platform. The support frame is fixedly mounted on the surface of the support plate. One end of the sleeve shaft is slidably mounted inside the support plate, and the other end of the sleeve shaft is slidably mounted inside the support frame. The weight is fixedly connected to the sleeve shaft, and the movable sleeve is rotatably mounted on the surface of the sleeve shaft.

[0011] Furthermore, the inner wall of the movable sleeve is in contact with the inner wall of the sleeve shaft, forming a rotatable connection.

[0012] Furthermore, the drive assembly includes a second motor, a first drive roller, a toothed block, and a second drive roller. The first and second drive rollers are both rotatably mounted on the surface of the support plate. The second motor is fixedly mounted on the surface of the support platform. The output end of the second motor is fixedly connected to the end of the second drive roller. The outer surfaces of the ends of the first and second drive rollers are both fixed with toothed blocks.

[0013] Furthermore, the first drive roller and the second drive roller are connected by their respective toothed blocks, the upper surface of the printing paper is in contact with the surface of the first drive roller, and the lower surface of the printing paper is in contact with the surface of the second drive roller.

[0014] Furthermore, the tray has a notch on the left side, and the two sets of cutters are located on the upper and lower sides of the notch on the left side of the tray, with the printing paper at the same distance from the two sets of cutters.

[0015] Compared with the prior art, the advantages of this utility model are as follows: 1. Starting the first motor drives the first gear to rotate. Due to the meshing connection between the first gear and the second gear, the rotation of the first gear will drive the second gear to rotate in the opposite direction. Since the guide rod is not at the center of the first gear and the second gear, the rotation of the first gear and the second gear will drive the first movable block and the second movable block to make circular motion. Since the first gear and the second gear rotate in opposite directions and at the same time, the two sets of cutters fixed at the ends of the first movable block and the second movable block will touch each other at a certain time. At this time, the printing paper between the two sets of cutters can be cut. Since the first gear and the second gear are the same size, the time for the two sets of cutters to touch each time is fixed, thereby achieving uniform cutting of the printing paper, so that the cut edge of the receipt is flat and aesthetically pleasing. 2. When the printing paper is loose, it is no longer taut, which reduces the tension of the printing paper on the weight block. As a result, the weight block pulls the sleeve shaft down by its own weight. The downward movement of the sleeve shaft will pull the movable sleeve down, increasing the distance between the printing paper on the surface of the movable sleeve and the printing paper on the surface of the tray. This will tighten the printing paper again and prevent uneven cuts on the receipt due to loose printing paper. 3. Before cutting the receipt, the second motor will be started to drive the cutter to rotate counterclockwise. Since the first drive roller and the second drive roller are connected by meshing tooth blocks, the first drive roller will rotate clockwise. The rotation of the two sets of drive rollers will drive the printing paper located between the first drive roller and the second drive roller to move in the direction of the cutter.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Example 1, please refer to the accompanying drawings in the specification. Figures 1-9 A guide belt cutting device includes a printer body 1, a support plate 2 and printing paper 18, and also includes a printing paper cutting component 3 and a printing paper clamping component 4. The support plate 2 is fixed inside the printer body 1, and the printing paper 18 is slidably placed on the support plate 5 fixed on the side surface of the support plate 2. The surface of the support plate 2 is equipped with a paper cutting component 3 that can uniformly cut the printing paper 18; The surface of the support plate 2 is equipped with a paper clamping component 4 that can prevent the printing paper 18 from loosening; The paper cutting component 3 is located to the side of the paper clamping component 4, and the paper cutting component 3 is closer to the paper output slot of the paper 18 outside the printer body 1 than the paper clamping component 4. The paper tensioning assembly 4 includes a tensioning assembly and a drive assembly. Both the tensioning assembly and the drive assembly are connected to the tray 5. The drive assembly is located to the side of the tensioning assembly and is closer to the paper output slot of the printer body 18 than the tensioning assembly.

[0021] Based on Embodiment 1, the printing paper cutting assembly 3 includes a first movable block 6, a first gear 7, a second movable block 8, a second gear 9, a support platform 11, a first motor 12, an annular block 13, a guide rod 14, and a cutter 15. The support platform 11 is fixedly mounted on the back surface of the support plate 2. The first motor 12 is fixedly mounted on the upper end of the support platform 11. The first gear 7 and the second gear 9 are rotatably mounted on the back surface of the support plate 2. The first gear 7 and the second gear 9 are meshed together. The first gear 7 and the second gear 9 have the same size. The output end of the first motor 12 is fixedly connected to the surface of the first gear 7. The annular block 13 and the guide rod 14 are fixedly mounted on the surfaces of the first gear 7 and the second gear 9, respectively. The first movable block 6 and the second movable block 8 are respectively fixed to the ends of the guide rod 14 on the surfaces of the first gear 7 and the second gear 9. The ends of the first movable block 6 and the second movable block 8 are both fixed with cutters 15, and the two sets of cutters 15 correspond to each other.

[0022] An annular groove 10 is provided on the back surface of the support plate 2, and the inner wall of the annular groove 10 is in a rotating connection with the outer surface of the annular block 13.

[0023] The tensioning assembly includes a weight 16, a support frame 17, a steering roller 19, a movable sleeve 22, and a sleeve shaft 23. The support platform 5 has a notch on its right side. Two sets of steering rollers 19 are respectively rotatably mounted at both ends of the notch on the right side of the support platform 5. The support frame 17 is fixedly mounted on the surface of the support plate 2. One end of the sleeve shaft 23 is slidably mounted inside the support plate 2, and the other end of the sleeve shaft 23 is slidably mounted inside the support frame 17. The weight 16 is fixedly connected to the sleeve shaft 23, and the movable sleeve 22 is rotatably mounted on the surface of the sleeve shaft 23.

[0024] The inner wall of the movable sleeve 22 is in contact with the inner wall of the sleeve shaft 23, forming a rotatable connection.

[0025] The drive assembly includes a second motor 20, a first drive roller 21, a toothed block 24, and a second drive roller 25. The first drive roller 21 and the second drive roller 25 are both rotatably mounted on the surface of the support plate 2. The second motor 20 is fixedly mounted on the surface of the support platform 5. The output end of the second motor 20 is fixedly connected to the end of the second drive roller 25. The outer surfaces of the ends of the first drive roller 21 and the second drive roller 25 are both fixed with toothed blocks 24.

[0026] The first drive roller 21 and the second drive roller 25 are connected by their respective toothed blocks 24. The upper surface of the printing paper 18 is in contact with the surface of the first drive roller 21, and the lower surface of the printing paper 18 is in contact with the surface of the second drive roller 25.

[0027] The tray 5 has a notch on the left side, and two sets of cutters 15 are located on the upper and lower sides of the notch on the left side of the tray 5. The distance between the printing paper 18 and the two sets of cutters 15 is the same.

[0028] In actual use, starting the first motor 12 drives the first gear 7 to rotate. Due to the meshing connection between the first gear 7 and the second gear 9, the rotation of the first gear 7 will drive the second gear 9 to rotate in the opposite direction. Since the guide rod 14 is not at the center of the first gear 7 and the second gear 9, the rotation of the first gear 7 and the second gear 9 will each drive the first movable block 6 and the second movable block 8 to make circular motion. Since the first gear 7 and the second gear 9 rotate in opposite directions and at the same time, the two sets of cutters 15 fixed at the ends of the first movable block 6 and the second movable block 8 will touch at a certain time. At this time, the printing paper 18 between the two sets of cutters 15 can be cut. Since the first gear 7 and the second gear 9 are the same size, the time for the two sets of cutters 15 to touch is fixed each time, thereby achieving uniform cutting of the printing paper 18, so that the cut edge of the receipt is flat and aesthetically pleasing. When the printing paper 18 is relaxed, it is no longer taut, thus reducing the tension of the printing paper 18 on the weight block 16. This causes the weight block 16 to pull the sleeve shaft 23 downward by its own weight. The downward movement of the sleeve shaft 23 will pull the movable sleeve 22 downward, increasing the distance between the printing paper 18 on the surface of the movable sleeve 22 and the printing paper 18 on the surface of the support 5. This causes the printing paper 18 to tighten again, preventing uneven cuts on the receipt due to the relaxation of the printing paper 18. Before cutting the receipt, the second motor 20 is started to drive the cutter 15 to rotate counterclockwise. Since the first drive roller 21 and the second drive roller 25 are connected by the meshing of the tooth block 24, the first drive roller 21 will rotate clockwise. The rotation of the two sets of drive rollers drives the printing paper 18 located between the first drive roller 21 and the second drive roller 25 to move towards the cutter 15.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
