Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, and in particular to a paper bending device for a slitting machine. Background Technology

[0002] Paper refers to thin sheets made from plant fibers, used for writing, drawing, printing books and newspapers, packaging, etc. A slitting machine is a mechanical device that cuts wide sheets of paper or film into multiple narrow strips of material, commonly used in industries such as papermaking machinery, printing machinery, and packaging machinery. During the slitting process, because paper is relatively soft and has a certain degree of elasticity and toughness, it is easily deformed, wrinkled, or shifted under the action of slitting force, thus affecting the accuracy and quality of slitting.

[0003] First, install and test the paper bending device and place it on the slitting machine to cut the paper. Then, start the device, and the paper will enter the bending device through the paper feeding system. The bending component will bend the paper at a preset angle. Finally, collect the cut fabric.

[0004] In existing technologies, some paper bending devices for slitting machines are used in a way that separates the slitting machine and the bending machine. The slitting paper is then manually transferred to the bending machine for bending. This method is inefficient and can easily damage the paper. Therefore, in order to address these shortcomings, a paper bending device for slitting machines is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a paper bending device for a slitting machine, which aims to improve the problem that some existing paper bending devices for slitting machines require manual transportation to the bending machine after slitting, and the transportation process leads to reduced efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A paper bending device for a slitting machine includes a feeding mechanism, a transport mechanism fixedly connected to the right side of the feeding mechanism, two upright plates fixedly connected to the top side of the transport mechanism, a cutting mechanism fixedly connected inside the two upright plates, and a bending mechanism fixedly connected to the right side of the transport mechanism. The cutting mechanism includes a positioning shaft, the positioning shaft being fixedly connected to the outside of the two upright plates, a trapezoidal plate being fixedly connected to the outside of the cutting mechanism, a transmission assembly being slidably connected inside the trapezoidal plate, a round shaft being fixedly connected to the left end of the transmission assembly via a fixing plate, two cutting plates being rotatably connected to the outside of the round shaft, and a side plate being included in the bending mechanism. The left side of the side plate is fixedly connected to the right side of the transport mechanism, a motor is fixedly connected to the rear end of the side plate via a cylinder, a rotating shaft is fixedly connected to the drive end of the motor, and a bending plate is fixedly connected to the outside of the rotating shaft.

[0008] Through the above technical solution: the slitting machine bending device consists of a feeding mechanism, a conveying mechanism, a cutting mechanism and a bending mechanism. The cutting mechanism is fixed on the vertical plate by a positioning shaft and uses a transmission component guided by a trapezoidal plate to drive the double cutting plates to rotate, so as to achieve precise slitting. The bending mechanism is driven by a motor-driven rotating shaft to move the bending plate and complete the paper forming operation. All mechanisms are connected in series through the conveying mechanism to form a continuous automated processing line, realizing integrated production of slitting and bending.

[0009] As a further description of the above technical solution:

[0010] The feeding mechanism includes a support platform, a fixed frame is fixedly connected to the top side of the support platform, a positioning plate is slidably connected inside the fixed frame, and feeding rollers are rotatably connected inside the two positioning plates.

[0011] The above technical solution achieves automatic paper positioning and smooth conveying by using a slidingly connected positioning plate in conjunction with the feeding roller, ensuring feeding accuracy.

[0012] As a further description of the above technical solution:

[0013] The transmission assembly includes a sliding rod, which is slidably connected to the outside of the trapezoidal plate, and a disc is fixedly connected to the right side of the sliding rod.

[0014] The above technical solution involves a sliding rod and a trapezoidal plate forming a guiding mechanism, with the right-side disc driving the cutting plate to move. This results in a compact structure and stable transmission, ensuring the accuracy of the cutting action.

[0015] As a further description of the above technical solution:

[0016] The transport mechanism includes two transport platforms. The left sides of the two transport platforms are fixedly connected to the right side of the support platform. A transport belt is installed inside the two transport platforms. A guide plate is fixedly connected to the top side of the transport platforms. Support legs are fixedly connected to the opposite sides of the two transport platforms. Protective boxes are fixedly connected to the opposite sides of the two support legs.

[0017] The above technical solution, which combines a dual transport platform with a transport belt and guide plate, and supports the legs and protective box to enhance stability, enables efficient paper transport while preventing deviation.

[0018] As a further description of the above technical solution:

[0019] The left side of the side plate is fixedly connected to the right side of the two transport platforms, and the bottom sides of the two cutting plates are in contact with the outside of the transport belt.

[0020] The above technical solution involves a rigid connection between the side plate and the transport platform, and a cutting plate that contacts the transport belt for cutting, forming an integrated cutting-transport process that improves processing efficiency.

[0021] As a further description of the above technical solution:

[0022] The left end of the sliding rod is fixedly connected to the inside of the fixed plate, and multiple limiting rings are fixedly connected to the outside of the circular shaft.

[0023] The above technical solution involves a sliding rod linked to a fixed plate and a circular shaft, with a limiting ring fixing the position of the cutting plate to prevent lateral displacement and ensure neat cutting edges.

[0024] As a further description of the above technical solution:

[0025] One of the two limiting rings is in contact with the front and rear sides of the cutting plate, and a positioning frame is fixedly connected to the top side of the side plate.

[0026] The above technical solution involves setting a positioning frame and a square opening at the top of the side panel, allowing the bending plate to rotate flexibly via a hinge, thus enabling precise bending of the paper at multiple angles.

[0027] As a further description of the above technical solution:

[0028] The top side of the side plate has a square opening, and the top side of the bent plate is fixedly connected to the left end of the top side of the side plate by two hinges.

[0029] The above technical solution involves a motor-driven shaft that moves the bending plate, combined with a flexible hinge connection, to adapt to the bending requirements of paper of different thicknesses, making operation convenient.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, paper is placed on a positioning plate, conveyed to a cutting plate by a conveyor belt, and cuts around an axis under the constraint of a limiting ring.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figures 1 to 3 The present invention provides an embodiment of a paper bending device for a slitting machine, comprising a feeding mechanism 1 for feeding square paper, the feeding mechanism 1 including a support platform 11 for providing support, a fixed frame 12 fixedly connected to the top side of the support platform 11 by welding, thereby providing support for the fixed frame 12, a positioning plate 13 slidably connected inside the fixed frame 12, the positioning plate 13 being able to slide stably by the restriction of the fixed frame 12, a feeding roller 14 being rotatably connected inside the two positioning plates 13, the feeding roller 14 being able to rotate stably for unwinding by the restriction of the positioning plates 13, and a transport mechanism 2 fixedly connected to the right side of the feeding mechanism 1, the feeding mechanism 1 providing support for the transport mechanism 2, the transport mechanism 2 including two transport platforms 21;

[0041] The left sides of the two transport platforms 21 are fixedly connected to the right sides of the support platform 11 by welding, thereby providing support for the two transport platforms 21. The two transport platforms 21 are equipped with transport belts 22. The paper is transported by starting the transport belts 22. The top side of the transport platform 21 is fixedly connected to the guide plate 23, which guides the paper during transport. The two transport platforms 21 are fixedly connected to the opposite sides of each other by welding, so that the support legs 24 can provide support for the transport platform 21. The opposite sides of the two support legs 24 are fixedly connected to the protective box 25 by welding, thereby providing support for the protective box 25.

[0042] Specifically, the feeding mechanism 1 uses a support platform 11 and a fixed frame 12 to form a rigid frame. The sliding positioning plate 13 can adjust the installation spacing of the feeding rollers 14 to adapt to different paper roll specifications. The transport mechanism 2 uses a double transport platform 21 to carry a synchronous transport belt 22, which, together with the guide plate 23, forms a precise paper feeding channel. The protective box 25 and the support leg 24 form a closed base that not only ensures the safety of the transmission components but also ensures the stability of the equipment operation. The whole system forms an adjustable feeding and directional conveying paper processing system, providing a precise and stable paper supply foundation for the subsequent bending process.

[0043] Reference Figures 1 to 3 The top side of the transport mechanism 2 is fixedly connected to two rectangular upright plates 3. A cutting mechanism 4 is fixedly connected inside the two upright plates 3, providing support through the constraint of the upright plates 3. The cutting mechanism 4 includes a positioning shaft 41, which is externally fixedly connected to the inside of the two upright plates 3 by welding, thus providing support for the positioning shaft 41. A trapezoidal plate 42 is externally fixedly connected to the cutting mechanism 4, and a transmission assembly 43 is slidably connected inside the trapezoidal plate 42. The transmission assembly is constrained by the trapezoidal plate 42. 43 can slide stably. The transmission component 43 includes a sliding rod 4301. The left end of the sliding rod 4301 is fixedly connected to the inside of the fixed plate 44 by welding, thereby providing support for the fixed plate 44. The outside of the sliding rod 4301 is slidably connected to the inside of the trapezoidal plate 42. The trapezoidal plate 42 restricts the sliding rod 4301 so that it can slide stably. The right side of the sliding rod 4301 is fixedly connected to a disc 4302 by welding, thereby providing support for the disc 4302 and preventing the sliding rod 4301 from slipping.

[0044] The left end of the transmission assembly 43 is fixedly connected to a round shaft 45 via a fixing plate 44. The sliding rod 4301 in the transmission assembly 43 is fixed to the fixing plate 44 by welding. Then, the fixing plate 44 is fixed to the round shaft 45 by welding, thereby driving the round shaft 45 to slide. Multiple limiting rings 46 are fixedly connected to the outside of the round shaft 45 by welding, thereby providing support for the limiting rings 46. Two cutting plates 47 are rotatably connected to the outside of the round shaft 45. By welding the round shaft 45, the cutting plates 47 can rotate stably and cut the paper. The adjacent side of the two limiting rings 46 is in contact with the front and rear sides of the cutting plates 47. By limiting the cutting plates 47, the cutting plates 47 can rotate stably. The bottom side of the two cutting plates 47 is in contact with the outside of the conveyor belt 22. The conveyor belt 22 provides support for the cutting plates 47 and the two are in contact.

[0045] Specifically, the cutting mechanism 4 achieves precise paper cutting through a linkage structure. The positioning shaft 41 supported by the upright plate 3 and the trapezoidal plate 42 form a rigid frame. The transmission component 43 slides horizontally within the trapezoidal plate 42 through the sliding rod 4301, driving the round shaft 45 and the limiting ring 46 to form an axial positioning system. The cutting plate 47 achieves rotational cutting with the round shaft 45 as the fulcrum. Its contact with the conveyor belt 22 ensures cutting force while avoiding damage to the conveyor belt. The whole mechanism forms a linkage mechanism of sliding drive plus rotational cutting. The axial displacement of the cutting plate 47 is precisely controlled by the limiting ring 46 to ensure the stability of the cutting operation and the flatness of the cut.

[0046] Reference Figure 1 , Figure 2 and Figure 4A bending mechanism 5 is fixedly connected to the right side of the transport mechanism 2. The bending mechanism 5 is used to bend the paper. The bending mechanism 5 includes a side plate 51. A positioning frame 52 is fixedly connected to the top side of the side plate 51. The left side of the side plate 51 is fixedly connected to the right side of the two transport tables 21 by welding, thus providing support for the side plate 51. The left side of the side plate 51 is fixedly connected to the right side of the transport mechanism 2. A motor 54 is fixedly connected to the rear end of the side plate 51 by a cylinder 53. The side plate 51 and the cylinder 53 are fixed by welding, and the cylinder 53 and the motor 54 are also fixed by welding, so that the motor 54 can be stably fixed. In operation, a rotating shaft 55 is fixedly connected to the drive end of the motor 54. The rotating shaft 55 is driven to rotate by starting the motor 54. A bending plate 56 is fixedly connected to the outside of the rotating shaft 55. The rotating shaft 55 drives the bending plate 56 to rotate and press against the paper to bend it. A square opening 57 is provided on the top side of the side plate 51. The square opening 57 provides a range of motion for the rotation of the bending plate 56. The top side of the bending plate 56 is fixedly connected to the left end of the top side of the side plate 51 by two hinges 58. By fixing one end of the hinge 58 to the left end of the side plate 51 and the right end of the hinge 58 to the top side of the bending plate 56, the bending plate 56 can rotate stably.

[0047] Specifically, the bending mechanism 5 adopts a motor 54 driven hinge structure to achieve precise bending of paper: the side plate 51 and the positioning frame 52 form a rigid support frame, the motor 54 drives the bending plate 56 to rotate within the range limited by the square opening 57 through the rotating shaft 55, and the symmetrical arrangement of the double hinges 58 not only ensures the rotational stability of the bending plate 56, but also forms a forced guiding structure, so that the bending plate 56 produces a precise bending angle when rotating.

[0048] Working principle: The paper is fed onto the roller by the positioning plate 13 and then falls onto the conveyor belt 22. The conveyor belt 22 is started to transport the paper. The paper then comes into contact with two cutting plates 47, which rotate around the circular shaft 45 and under the restriction of the limiting ring 46, so as to cut the paper into three sheets. As needed, the fixed plate 44 can be moved by pulling the sliding rod 4301, which in turn drives the cutting plates 47 to rotate. The paper is then transported stably under the restriction of the two guide plates 23.

[0049] The paper then continues to be transported through the opening at the bottom of the positioning frame 52. At this time, the Rongguang start motor 54 drives the rotating shaft 55 to rotate, which in turn drives the bending plate 56 to rotate, so that it can lift the paper until the bending plate 56 is vertical and bends the paper to fit the positioning frame 52. Then it continues to be transported to the next process.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
