DETAILED DESCRIPTION

[0025] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0026] See also Figures 1 to 5The present invention provides a printing device for synchronously printing different varieties, including a base 2 and a rebound mechanism. A U-shaped frame 21 is fixedly provided on the upper surface of the base 2. A platform 22 is fixedly provided inside the frame 21. The platform 22 is used to flatten the label belt 19. Three printing modules are arranged at intervals on the top of the frame 21. Three release components and three rewinding components are respectively arranged on both sides outside the frame 21. The release components, rewinding components and printing modules of each group are aligned and matched with each other. The label belt 19 is connected between the release components and the rewinding components. The release components are arranged on the top of the frame 21. The rewinding components are arranged on the bottom ... The unprinted label tape 19 is wound up by the component, and the label tape 19 is formed by connecting a plurality of labels end to end. Specifically, a plurality of blank labels are sequentially pasted on a long strip bottom tape with good tensile strength. The blank label refers to an unprinted label. The winding component can pull out the label tape 19 on the release component one by one, so that the labels can be moved one by one to and spread flat on the preset position on the upper surface of the platform 22. The printing module can print the labels on the platform 22. Each winding component includes two electric slides arranged at intervals on the upper surface of the base 2 and two electric slides arranged on the upper surface of the base 2. The support part between the platforms is fixed on the upper surface of the base 2, and the upper surface of the support part is flush with the upper surface of the platform 22. The upper surface of the support part, the upper surface of the base 2 and the upper surface of the platform 22 are flush. Guide rods 4 are fixed on both sides of the upper surface of each electric slide. A slider 9 is provided on the common sliding sleeve of the two guide rods 4. The slider 9 is connected to a sleeve 11 through a one-way bearing 10. A reel 24 is detachably connected between the two sleeves 11. The reel 24 can be connected to the head end of the label belt 19. The rebound mechanism is connected to the slider. Between the upper surface of 9 and the top of the guide rod 4, the slider 9 can generate a downward movement trend, which is used to press the lower side of the label tape 19 rolled up on the roller 24 against the upper surface of the support portion, so that when the electric slide drives the roller 24 to move away from the frame 21, the roller 24 cannot drive the sleeve 11 to rotate on the slider 9, and when the electric slide drives the roller 24 to move towards the frame 21, the roller 24 drives the sleeve 11 to rotate on the slider 9, and the roller 24 rolls on the upper surface of the support portion and rolls up the label tape 19;

[0027] The present invention can synchronously print three labels of different specifications by setting three sets of matching printing modules, release components and reel components. The reel component can be used to pull out the label belt 19 on the release component according to the length of the label, so that the three labels on the three release components can be synchronously moved one by one to and spread flat on the upper surface of the platform 22. The printing module can print the labels on the platform 22, and can synchronously print paper and plastic labels of multiple specifications, which greatly improves the printing efficiency and is suitable for mass production needs. It should be noted that more sets of matching printing modules, release components and reel components can be set according to specific needs, and no limitation is made here.

[0028] According to the length of different labels, the present invention sets the one-way moving distance of each group of electric slides (two electric slides in the same group) to be the distance between the centers of two corresponding adjacent labels. Since the lower end of the rolled label belt 19 is kept pressed against the upper surface of the support part under the action of the rebound mechanism, and the upper surface of the support part is flush with the upper surface of the platform 22, the moving path of the electric slide is parallel to the label belt 19 between the platform 22 and the roller 24. By utilizing the one-way transmission effect of the one-way bearing 10, the roller 24 does not The sleeve 11 can be driven to rotate counterclockwise on the slider 9, and can only be driven to rotate clockwise on the slider 9. Therefore, when the electric slide drives the roller 24 through the guide rod 4, the slider 9, the one-way bearing 10 and the sleeve 11, the sleeve 11 and the roller 24 are equivalent to being locked on the slider 9. At this time, the roller 24 drives the rolled label belt 19 to slide on the upper surface of the support part away from the frame 21, and it does not release and roll. The label tape 19 on the winding roller 24 is simply pulled out from the release assembly as the electric slide moves, and the unprinted label tape 19 is pulled to the preset printing position on the platform 22, and the wound label tape 19 is moved to the left side of the upper surface of the support portion. When the electric slide drives the winding roller 24 to move toward the frame 21 through the guide rod 4, the slider 9, the one-way bearing 10 and the sleeve 11, the rebound mechanism is moved through the slider 9, the one-way bearing 10, and the sleeve 11. , the sleeve 11 and the roller 24 drive the lower side of the printed and rolled-up label tape 19 to press against the upper surface of the support portion. Since the roller 24 can drive the sleeve 11 to rotate on the slider 9, the roller 24 drives the rolled-up label tape 19 thereon to roll on the upper surface of the support portion to roll up the label tape 19. In this way, the label tape 19 can be quickly released and rolled up back and forth. The control algorithm is simple, and the overall structure of the present invention is simple and small in size, which reduces the floor space of the factory building and facilitates the layout of production equipment.
