[0024] like Figure 1As shown, this application provides a paper feeding device, which includes a support plate 100, a conveyor belt 200, and a first roller 310 assembly 300. The rolled paper falls onto the support plate 100 after being pulled. The conveyor belt 200 passes through the support plate 100. The first roller 310 assembly 300 includes a first roller 310 and a second roller 320. The first roller 310 passes through the support plate 100, and the second roller 320 is arranged parallel to and spaced apart from the first roller 310. The first roller 310 and the second roller 320 clamp the paper to prevent the paper from tilting during movement. The conveyor belt 200 is linked with the first roller 310.

[0025] In one specific embodiment, the support plate 100 is generally rectangular. The support plate 100 is the basic support component of the entire pad paper feeding device. It is usually made of metal or high-strength engineering plastic and has sufficient flatness and strength. Its main function is to provide a stable placement surface for the pad paper.

[0026] The conveyor belt 200 is generally made of wear-resistant and flexible rubber or composite material. Connected to a power source, it rotates in a cycle, thereby moving the padding paper placed on it along a predetermined direction. It is the key power transmission medium for padding paper conveying. The conveyor belt 200 is located below the support plate 100 and penetrates through the support plate 100 so that it can contact the padding paper on the support plate 100.

[0027] The first roller 310 and the second roller 320 in the first roller assembly 300 are both cylindrical, with matching external dimensions, and are installed in a parallel and spaced state. The first roller 310 is located below the second roller 320 and passes through the support plate 100 so that the first roller 310 can contact the padding paper on the support plate 100. The distance between the first roller 310 and the second roller 320 is reasonably set according to factors such as the thickness of the padding paper, so that the padding paper can pass smoothly between them. At the same time, the first roller 310 and the second roller 320 apply appropriate pressure to both sides of the padding paper to clamp the padding paper together, thereby limiting the padding paper's random swing in the lateral direction and preventing it from tilting during movement. The conveyor belt 200 is linked with the first roller 310, so that when the conveyor belt 200 rotates, it can drive the first roller 310 to rotate synchronously, thereby enabling the first roller 310 to provide power for the movement of the pad paper on the support plate 100, ensuring that the pad paper always moves steadily along the correct path.

[0028] like Figure 2As shown, the padding paper feeding device also includes a second roller 320 assembly, which includes a third roller 410. The third roller 410 is arranged parallel to and spaced apart from the conveyor belt 200. The third roller 410 and the conveyor belt 200 clamp the padding paper to prevent the padding paper from tilting during movement, and the second roller 320 is linked with the conveyor belt 200.

[0029] In one specific embodiment, the second roller 320 assembly further supplements and enhances the function of the first roller 310 assembly 300. The third roller 410, as the core component of the second roller 320 assembly, must possess good wear resistance, surface smoothness, and appropriate hardness to ensure that it does not damage the padding paper during long-term contact. The third roller 410 is parallel and spaced apart from the conveyor belt 200, meaning that another space is formed between them for clamping the padding paper. When the padding paper moves forward under the drive of the conveyor belt 200, the third roller 410 applies a certain pressure to the padding paper from one side, working together with the conveyor belt 200 to form a double-sided constraint on the padding paper, further limiting its sway and enhancing the entire device's ability to prevent the padding paper from tilting. This allows the padding paper to achieve more comprehensive and stable positioning during transport.

[0030] A mechanical connection is established between the second roller 320 and the conveyor belt 200 to keep them moving synchronously, ensuring that the rotation speed and direction of the second roller 320 are coordinated with the movement state of the conveyor belt 200, so as to stably drive the pad paper to move on the support plate 100.

[0031] like Figure 2 As shown, the padding paper feeding device also includes a first assembly plate 110 and a second assembly plate 120. The first assembly plate 110 and the second assembly plate 120 are fixedly installed on both sides of the support plate 100. The first roller 310 assembly 300 and the second roller 320 assembly are installed based on the first assembly plate 110 and the second assembly plate 120.

[0032] In one specific embodiment, the first assembly plate 110 and the second assembly plate 120 are two plates arranged in parallel and spaced apart. The first assembly plate 110 and the second assembly plate 120 are respectively fixedly assembled on both sides of the support plate 100, and the first assembly plate 110 and the second assembly plate 120 are arranged vertically. The first assembly plate 110 and the second assembly plate 120 provide a foundation for the installation of the first roller 310 assembly 300 and the second roller 320 assembly.

[0033] like Figure 2 As shown, the paper feeding device also includes two parallel baffles 130, which are fixedly assembled with the support plate 100. The baffles 130 and the support plate 100 enclose a movement channel for the paper.

[0034] In one specific embodiment, the baffle 130 is generally rectangular, and two baffles 130 are provided, arranged parallel and spaced apart. The distance between them is reasonably designed according to the standard width of the padding paper and a certain allowance. Then, they are fixedly assembled with the first support plate 100 through a strong connection method such as welding and screw fixing, so that the file and the support plate 100 enclose a specific movement channel. This movement channel plays a clear guiding role for the padding paper, restricting the excessive swing of the padding paper in the width direction, so that the padding paper can only move forward along the direction specified by the channel. Even in the presence of some external interference factors, it can be ensured that the padding paper will not deviate from the preset conveying route, further improving the stability of the padding paper conveying.

[0035] The padding paper feeding device also includes several fixing rods, one end of which is fixedly connected to the first assembly plate 110 and the other end of which is fixedly connected to the second assembly plate 120.

[0036] In one specific embodiment, the fixing rods are cylindrical, and several fixing rods are horizontally arranged between the first assembly plate 110 and the second assembly plate 120. One end of the fixing rod is connected to the first assembly plate 110 by a reliable fixing method such as welding or threaded connection, and the other end is also firmly connected to the second assembly plate 120, forming a frame-like reinforced structure. The main function of the fixing rods is to fix the first assembly plate 110 and the second assembly plate 120, preventing relative displacement or deformation between the two assembly plates during long-term operation of the device.

[0037] like Figure 2 As shown, the padding paper feeding device also includes a driving device 500, a first transmission rod 210, and a second transmission rod 220. The first transmission rod 210 and the second transmission rod 220 are arranged in parallel and spaced apart. The conveyor belt 200 is sleeved on the first transmission rod 210 and the second transmission rod 220. The driving device 500 is used to drive the first transmission rod 210 to rotate.

[0038] In one specific embodiment, the drive device 500 is an electric motor, which is the power source of the entire paper feeding device and provides power support for the operation of the device. The first transmission rod 210 and the second transmission rod 220 are parallel and spaced apart below the support plate 100. The drive device 500 is fixedly mounted on the first assembly plate 110, and the first transmission rod 210 and the second transmission rod 220 are rotatably mounted on the first assembly plate 110 and the second assembly plate 120. The paper feeding device also includes a third belt 211 and a fourth belt 221. The output end of the drive device 500 is connected to the end of the first transmission rod 210 via the third belt 211, enabling the drive device 500 to drive the first transmission rod 210 to rotate. The end of the first transmission rod 210 away from the third belt 211 is connected to the second transmission rod 220 via the fourth belt 221, causing the first transmission rod 210 and the second transmission rod 220 to move together.

[0039] The conveyor belt 200 is fitted in the middle of the first transmission rod 210 and the second transmission rod 220. The conveyor belt 200 moves by relying on the friction between itself and the first transmission rod 210 and the second transmission rod 220, as well as the rotation of the first transmission rod 210 and the second transmission rod 220, thereby driving the pad paper to be conveyed.

[0040] The padding paper feeding device also includes a first guide wheel 150, which is located between the first transmission rod 210 and the second transmission rod 220. The first guide wheel 150 is fixedly assembled with the second mounting plate 120. The fourth belt 221 passes around the first guide wheel 150, making the fourth belt 221 triangular. This optimizes the contact area and contact angle between the fourth belt 221 and the first transmission rod 210 and the second transmission rod 220, increasing friction and facilitating stable and reliable transmission of power from the drive device 500.

[0041] like Figure 2 As shown, the first roller assembly also includes a first mounting rod 330 and a second mounting rod 340. The first roller 310 is disposed on the first mounting rod 330, and the second roller 320 is disposed on the second mounting rod 340. The second roller 320 assembly also includes a third mounting rod 420, and the third roller 410 is disposed on the third mounting rod 420.

[0042] In one specific embodiment, the first mounting rod 330 and the second mounting rod 340 are components for mounting the first roller 310 and the second roller 320 in the first roller 310 assembly 300. The first mounting rod 330 is located below the support plate 100, and the second mounting rod 340 is located above the support plate 100. The first mounting rod 330 and the second mounting rod 340 are parallel, and their two ends are rotatably connected to the first assembly plate 110 and the second assembly plate 120, respectively. The first roller 310 is fixed to the middle of the first mounting rod 330, and the second roller 320 is rotatably mounted to the middle of the second mounting rod 340.

[0043] The third mounting rod 420 is provided for mounting the third roller 410 in the second roller 320 assembly. The third mounting rod 420 is located above the support plate 100. The first mounting rod 330, the second mounting rod 340 and the third mounting rod 420 are parallel to each other. One end of the third mounting rod 420 is rotatably connected to the second assembly plate 120. The third roller 410 is fixedly connected to the end of the third mounting rod 420 away from the second assembly plate 120.

[0044] like Figure 2As shown, the padding paper feeding device also includes a first belt 600 and a second belt 700. One end of the second transmission rod 220 is linked to the third mounting rod 420 via the first belt 600, and the end of the second transmission rod 220 away from the first belt 600 is linked to the first mounting rod 330 via the second belt 700.

[0045] In one specific embodiment, the end of the second transmission rod 220 near the second mounting plate 120 is connected to the third mounting rod 420 via a first belt 600, thereby achieving linkage between the second transmission rod 220 and the third mounting rod 420. The end of the second transmission rod 220 away from the first belt 600 is connected to the first mounting rod 330 via a second belt 700, thereby achieving linkage between the second transmission rod 220 and the first mounting rod 330.

[0046] The paper feeding device also includes a second guide wheel 160 and a third guide wheel 170. Both the second guide wheel 160 and the third guide wheel 170 are rotatably mounted on the second assembly plate 120. The first belt 600 passes around the second guide wheel 160, making the first belt 600 triangular, so as to optimize the transmission effect of the first belt 600. The third guide wheel 170 is located between the second transmission rod 220 and the second guide wheel 160. The third guide wheel 170 is used to change the direction of the first belt 600, so as to further optimize the transmission effect of the first belt 600.

[0047] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
