DETAILED DESCRIPTION

[0021] The following is further described in detail through specific implementation methods:

[0022] See Figure 1 、 Figure 2 as well as Figure 3 The present invention provides an upper and lower paper winding device for installing and removing a paper roll from a printing device 1, comprising a support base 2, a support rod 3 arranged longitudinally along the support base 2, a slider 4 slidably connected to the support rod 3, and a drive assembly 5 for driving the slider 4 to slide along the support rod 3. The support rod 3 is rotatably connected to the support base 2, and the slider 4 is provided with a through-hole 41 extending vertically through the slider 4. The slider is slidably sleeved on the outer circumference of the support rod 3 through the through-hole 41. The slider 4 is provided with a bearing rod 6 in the horizontal direction, one end of the bearing rod 6 is fixedly connected to one side of the slider 4, and the other end of the bearing rod 6 axially extends through the paper roll. When loading, the slider 4 is lowered by the driving component 5, and after the roll of paper to be loaded is placed on the supporting rod 6, the support rod 3 is rotated so that the supporting rod 6 faces the printing device 1, and then the slider 4 is driven to rise by the driving component 5. When the supporting rod 6 moves to the installation position, the staff pushes the roll of paper on the supporting rod 6 to the printing device 1; when unloading is required, the supporting rod 6 is adjusted to face the printing device 1, the roll of paper is moved onto the supporting rod 6, and then the slider 4 is moved downward by the driving component 5. When the slider 4 drops to a certain position, the support rod 3 is rotated, and the supporting rod 6 is rotated to the unloading area for unloading.

[0023] The support base 2 is bolted to the ground. A servo motor (not shown) is housed within the support base 2 to drive the support rod 3. The servo motor's output is connected to the bottom of the support rod 3, driving the rotation of the support rod 3. Since paper rolls are typically placed on one side of the printing device 1, after placing the paper roll onto the support rod 6, the support rod 3 must be rotated to align the paper roll with the printing device 1, facing the printing device 1. The servo motor can also drive the support rod 3 to rotate horizontally, facilitating loading and unloading.

[0024] In order to increase the speed of the paper roll on the support rod 6, improve the moving efficiency, reduce the friction between the paper roll and the support rod, and make the paper roll move more effortlessly on the support rod 6, the upper surface of the support rod 6 is provided with a chute 61 along the length direction of the support rod 6, and a number of rollers 611 are arranged at intervals in the chute 61. When loading is needed, the paper roll only needs to be moved to the end of the support rod 6, so that the inner wall of the paper roll drum in the middle of the paper roll abuts against the top of the roller 611, and then the paper roll can be moved to the end near the slider 4 by gently pushing it. When unloading is needed, the servo motor first drives the support rod 3 to rotate so that the support rod 6 faces the printing device 1, and then the printed paper roll is moved to the support rod 6. The slider 4 is then lowered by the drive assembly 5. When the slider is lowered to a certain height, the servo motor drives the support rod 3 to rotate, so that the support rod 6 rotates to the unloading area and the printed paper roll is unloaded from the support rod 6. In order to ensure that the paper roll can fully contact the roller 611, in this embodiment, the tops of the rollers 611 are all protruding from the top of the chute 6, and the rollers 611 are arranged on the same horizontal line. The provision of the rollers 611 can reduce the friction between the paper roll and the support rod 6, making it easier to move the paper roll on the support rod 6 and saving workers more effort.

[0025] Please continue to see Figure 4 and Figure 5To limit the travel of the slider 4 during the loading process and prevent it from falling off the support rod 3, a first mounting plate 31 and a second mounting plate 32 are provided at the top and bottom of the support rod 3, respectively. The first mounting plate 31 and the second mounting plate 32 are used to limit the travel of the slider 4. The first mounting plate 31 and the second mounting plate 32 can limit the position of the slider 4 and prevent it from falling off the support rod 3. To facilitate installation and removal, the first mounting plate 31 and the second mounting plate 32 are detachably connected to the ends of the support rod 3 and are fixed to the ends of the support rod 3 by bolts. Specifically, the first mounting plate 31 and the second mounting plate 32 are provided on the side where the first mounting plate 31 and the second mounting plate 32 are connected to the support rod 3, respectively, to form a first groove 311 and a second groove 321 for the support rod 3 to be inserted. After the ends of the support rod 3 are inserted into the first groove 311 and the second groove 321, the first mounting plate 31 and the second mounting plate 32 are locked and fixed to the ends of the support rod 3 by bolts.

[0026] After the paper roll is positioned on the support rod 6, in order to control the raising and lowering of the slider 4, in this embodiment, the drive assembly 5 includes a drive motor 51 and a threaded rod 52. The drive motor 51 is disposed on the first mounting plate 31. The threaded rod 52 is longitudinally rotatably connected between the first mounting plate 31 and the second mounting plate 32. The output end of the drive motor 51 is in transmission connection with the threaded rod 52, and the slider 4 is threadedly connected to the threaded rod 52. Specifically, a threaded hole 42 is provided on the slider 4 on one side of the perforation 41, and the slider is threadedly connected to the threaded rod 52 through the threaded hole 42. The second mounting plate 32 is provided with a third groove 322 for positioning the threaded rod 52, and one end of the threaded rod 52 abuts the bottom surface of the third groove 322. When the drive motor 51 drives the threaded rod 52 to rotate, since the slider 4 is slidably connected to the support rod 3, the support rod 3 can longitudinally limit the slider 4. Therefore, when the threaded rod 52 rotates, the threaded connection between the slider 4 and the threaded rod 52 allows the slider 4 to move in the vertical direction. For ease of use, a control box 7 is further provided on the first mounting plate 31 . The control box 7 is electrically connected to the drive motor 51 and the servo motor. The operation of the drive motor 51 and the servo motor can be controlled by the control box 7 during use.

[0027] When the slider 4 rises to a certain height, a block 62 is provided on the end of the support rod 6 facing away from the slider 4 to facilitate its connection with the printing device 1. This block 62 has a latch 621 that mates with the mounting shaft 11. When the support rod 6 moves relative to the mounting shaft 11, the block 62 engages with the mounting shaft 11, integrating the support rod 6 and the mounting shaft 11. Once the block 62 engages with the mounting shaft 11, the staff member pushes the paper roll on the support rod toward the mounting shaft 11. To load paper, the staff member can rotate the support rod 6 before raising it, or raise it first and then rotate it. Therefore, to accommodate different loading methods, the block 62 is rotatably connected to the end of the support rod 6 facing away from the slider 4. When the support rod 6 is above or below the mounting shaft 11, the open end of the latch 621 faces the mounting shaft 11 vertically. When the support rod 6 is to the left or right of the mounting shaft 11, the open end of the latch 621 faces the mounting shaft 11 horizontally. Therefore, when the staff is in use, they can first rotate the supporting rod 6 so that it faces the printing device 1 and then raise the supporting rod 6 so that the block 62 is engaged with the mounting shaft 11 in the vertical direction. Similarly, the supporting rod 6 can also be raised to a certain height first, and then the supporting rod 6 is rotated so that the block 62 is engaged with the mounting shaft 11 in the horizontal direction, which is more applicable. It should be noted that the block 62 and the supporting rod 6 are connected by damping rotation. Through this design, the block 62 will not easily rotate. In this embodiment, setting the bayonet 621 to a "V" shape can make its opening width wider, making it easier for the block 62 to engage with the mounting shaft 11. At the same time, setting the bayonet 621 to a "V" shape can make the block 62 more firmly engaged with the mounting shaft 11. During the process of engaging the block 62 with the mounting shaft 11, the width of the bayonet 621 gradually decreases, so the engagement with the mounting shaft 11 can be more secure, and no shaking will occur during the process of moving the roll of paper.

[0028] The above are merely examples of the present invention, and the well-known specific structures and characteristics of the scheme are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these modifications should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention and the practicality of the present invention.
