[0002] The wood grain paper traction machine is an important piece of equipment used in the production and processing of wood grain paper. It is mainly used to pull the wood grain paper from the unwinding device to the subsequent processing equipment or the rewinding device. While ensuring the smooth transmission of the wood grain paper, it ensures that its tension is uniform and its position is accurate to meet the production process requirements.

[0003] Some existing wood grain paper traction machines use multiple bolts or clamps to fix the take-up drum. When changing the take-up drum, the operator needs to loosen these bolts or clamps one by one. The operation is cumbersome. Moreover, the position and size of these fixing parts are usually fixed, making it difficult to quickly adjust according to the inner diameter of different take-up drums, thus reducing the traction efficiency. Therefore, a breakage-resistant wood grain paper traction machine is proposed to solve the above problems. Utility Model Content

[0030] 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.

[0031] Referring to Figures 1-3, one embodiment of this utility model provides an anti-breakage wood grain paper traction machine, including a base 1, which serves as the basic support structure for the entire traction machine. A support frame 2 is fixedly connected to the middle of the base 1, providing support and guidance for the contact element 3. The contact element 3 is slidably connected to the inner wall of the support frame 2, directly contacting the wood grain paper. During the traction process, it presses and guides the wood grain paper, ensuring that the wood grain paper can be stably conveyed along a predetermined path. A pressure sensor 4 is fixedly connected to the upper part of the contact element 3. An electric telescopic rod 5 is fixedly connected through the upper part of the support frame 2. The electric telescopic rod 5 extends or shortens, thereby adjusting the height of the contact element 3 and changing the pressure of the contact element 3 on the wood grain paper, achieving precise control of the traction pressure of the wood grain paper and effectively preventing the wood grain paper from breaking during traction. The output shaft of the electric telescopic rod 5 is fixedly connected to the upper part of the pressure sensor 4. The pressure sensor 4 monitors the pressure of the contact element 3 on the wood grain paper in real time and converts the pressure signal into an electrical signal, which is used by the electric telescopic rod 5 to adjust the contact element 3. The position provides a basis for ensuring that the pressure on the wood grain paper is uniform during the traction process, and prevents the wood grain paper from breaking due to excessive pressure. A fixing component 6 is provided on the left side of the base 1, and a support component 7 is provided on the rear side of the fixing component 6.

[0032] Referring to Figures 1-3, the fixing assembly 6 includes a support cylinder 61 rotatably connected to the upper part of the base 1, providing a sliding track for the movable part 62 and the support part 64 for accommodating the take-up drum of wood grain paper. The movable part 62 is slidably connected to the inner wall of the support cylinder 61, and its movement drives the fixed column 63 to move, thereby adjusting the position of the fixed column 63 to accommodate take-up drums of different sizes of wood grain paper, thus achieving the fixing and positioning of the take-up drum. The fixed column 63 is fixedly connected to the inner wall of the movable part 62, and cooperates with the slide groove 65 to control the sliding of the support part 64 on the inner wall of the support cylinder 61. Multiple sets of support parts 64 are slidably connected to the inner wall of the support cylinder 61 to squeeze and limit the inner side of the take-up drum, ensuring that the take-up drum is firmly fixed. The slide groove 65 is opened on the outer side of the support part 64. The slide groove 65 is inclined, and the inclined slide groove 65 can guide the movement of the fixed column 63 when it moves. A transmission wheel 68 is fixedly connected to the front side of the support cylinder 61, and is driven by the drive motor 8 through a belt, thereby driving the fixing assembly 6. The winding mechanism rotates to rewind the cylinder. A lead screw 66 is rotatably connected to the inner wall of the support cylinder 61 via the drive wheel 68. When the lead screw 66 is rotated, the moving part 62 can be driven to slide inside the support cylinder 61 through the threaded transmission, thereby precisely adjusting the position of the fixed column 63 and achieving precise fixation of winding cylinders of different sizes. A crank handle 67 is fixedly connected to the front side of the lead screw 66. The operator can rotate the crank handle 67 to drive the lead screw 66 to rotate, which is convenient and labor-saving. A limit component 9 is provided on the outside of the crank handle 67.

[0033] Referring to Figures 1 and 2, the support assembly 7 includes a support rod 71 rotatably connected to the inner wall of the base 1, supporting the rear side of the support cylinder 61. A slot 74 is provided through the outer side of the support rod 71, which cooperates with the limiting member 73 to rotatably limit the support rod 71. A fixing frame 72 is fixedly connected to the upper part of the base 1 to limit the support rod 71 in the upright state. A limiting member 73 is rotatably connected through the outer side of the fixing frame 72, which rotatably passes through the inner wall of the slot 74. By rotating the limiting member 73, it can be inserted into or disengaged from the slot 74, thereby limiting and unlocking the support rod 71. The rear side of the fixing frame 72 is L-shaped. The fixing post 63 slides on the inner wall of the slide groove 65. The lead screw 66 is threaded to the inner wall of the moving part 62. A rubber pad is provided at the connection between the limiting member 73 and the fixing frame 72 to increase friction, prevent the limiting member 73 from loosening, and improve the reliability of the limiting.

[0034] Refer to Figure 1 and Figure 4The limiting component 9 includes a connector 91 slidably connected to the outside of the crank handle 67. The connector 91 rotates together with the crank handle 67. By inserting or pulling out the transmission wheel 68, the connection between the lead screw 66 and the support cylinder 61 is locked and unlocked. The rear side of the connector 91 is inserted into the inner wall of the transmission wheel 68. The crank handle 67 is elastically connected to the connector 91 through a compression spring 92, which provides elastic force to the connector 91, allowing it to insert into the inner wall of the transmission wheel 68, preventing the lead screw 66 from loosening and ensuring the stability of the fixing component 6. A pull handle is fixedly connected to the outside of the connector 91, making it easy for the operator to pull the connector 91 to disengage it from the transmission wheel 68, facilitating manual rotation of the crank handle 67 to adjust the fixing component 6. A drive motor 8 is fixedly connected to the upper part of the base 1, providing rotational power to the fixing component 6 for winding. The output shaft of the drive motor 8 passes through the base 1. Two sets of transmission wheels 68 are provided. The other set of transmission wheels 68 Fixedly connected to the output shaft of the drive motor 8, the two sets of transmission wheels 68 are connected by belt drive.

[0035] Working principle: When in use, the wood grain paper take-up tube is put on the support tube 61, so that the center hole of the take-up tube is aligned with the fixed post 63 and inserted. Pull the handle on the outside of the plug-in 91 to overcome the elastic force of the compression spring 92 and make the plug-in 91 disengage from the transmission wheel 68. At this time, the rocker handle 67 can be turned to adjust the fixed component 6.

[0036] Turning the crank handle 67 causes the lead screw 66 to rotate. The lead screw 66, through threaded transmission, causes the moving part 62 to slide within the support cylinder 61, thereby moving the fixed column 63. The fixed column 63 slides on the inner wall of the groove 65 on the support part 64, causing the support part 64 to slide within the support cylinder 61. Its outer side is in close contact with the inner side of the winding drum, providing multi-point support, enhancing the stability of the winding drum, and preventing swaying or deviation during traction. After installation, the connector 91 is released. Under the action of the compression spring 92, the connector 91 is inserted into the inner wall of the transmission wheel 68, connecting the lead screw 66 to the support cylinder 61, preventing the lead screw 66 from loosening, and ensuring the stability of the fixed assembly 6 during operation.

[0037] The drive motor 8 is started, and through belt drive, another set of transmission wheels 68 connected to the support cylinder 61 also rotates, thereby driving the support cylinder 61 and the winding drum to rotate, realizing the winding and traction of the wood grain paper. During the traction process, the contact element 3 is in direct contact with the wood grain paper, and the pressure sensor 4 monitors the pressure of the contact element 3 on the wood grain paper in real time. If the pressure is too high or too low, the pressure sensor 4 transmits a signal to the control system, and the control system controls the electric telescopic rod 5 to extend or shorten. The extension and retraction of the electric telescopic rod 5 causes the pressure sensor 4 and the contact element 3 to move up and down, adjusting the pressure of the contact element 3 on the wood grain paper to ensure that the pressure on the wood grain paper is uniform during the traction process, avoiding breakage of the wood grain paper due to uneven pressure.

[0038] 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.
