Description

Technical Field

[0001] This utility model relates to the field of rubber blanket application technology, and in particular to a rapid application device for printing plate adhesive rubber blanket. Background Technology

[0002] In the printing industry, the bonding of printing plates and adhesive rubber blankets is one of the key processes. The quality of bonding directly affects the final effect of the printed products. If the bonding is not smooth, problems such as uneven ink color and ghosting of text or patterns will occur during printing, which will seriously affect the printing quality.

[0003] Traditional methods of applying adhesive-backed rubber blankets to printing plates mainly rely on manual operation. Operators need to rely on experience and feel to gradually attach the rubber blanket to the printing plate. However, manual operation has many drawbacks. Due to the lack of effective positioning and fixing devices, the printing plate and rubber blanket are prone to relative movement during the application process, resulting in inaccurate positioning, uneven edges of the rubber blanket, or even skewing. This increases the difficulty of subsequent cutting and the scrap rate. It is also difficult to ensure uniformity when applying pressure. During the application process, there is a tendency for local pressure to be too high or too low. Excessive pressure may cause the rubber blanket to be overstretched and deformed, while insufficient pressure will result in a loose bond between the rubber blanket and the printing plate, creating air bubbles or gaps, which in turn affects the printing quality.

[0004] To overcome the shortcomings of traditional manual application methods, improve the application quality, efficiency, and stability of printing plate adhesive blankets, and reduce scrap rates and production costs, developing a convenient and rapid application device for printing plate adhesive blankets is of significant practical importance.

[0007] A rapid application device for printing plate adhesive blankets includes a base, a winding assembly for winding the blanket body is installed on the top of the base, an abutment plate is welded to the top of the base, and the printing plate body is placed on the base. A slide assembly is installed on the outer wall of the top of the base, a sliding plate is movably connected to the slide assembly, an elastic element is installed on the sliding plate, and a bracket is fixed to the bottom of the elastic element. Pressure rollers are movably connected to the inner walls on both sides of the bracket.

[0008] As a further embodiment of this utility model: the slide assembly includes a slide body and a guide plate. The slide body is fixed to the top outer wall of the base, and the guide plate is fixed to the inner walls on both sides of the slide body by screws, and the guide plate and the slide plate are movably connected.

[0009] As a further embodiment of this utility model: the elastic element includes a spring and a T-shaped rod. The T-shaped rod is movably connected to the inner wall of the through hole opened on the surface of the sliding plate. The bottom of the T-shaped rod and the top of the bracket are fixedly connected. The spring is sleeved on the outer wall of the T-shaped rod, and the two ends of the spring are respectively fixed to the top outer wall of the sliding plate and the top inner wall of the T-shaped rod.

[0010] As a further embodiment of this utility model: the winding assembly includes a vertical plate and a winding column. The vertical plate is fixed to the outer wall of the top of the base by screws, and the winding column is movably connected to the inner wall of the through hole opened on the surface of the vertical plate.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] A rapid application device for adhesive-backed printing plate blankets, in order to ensure flat application, such as... Figures 1 to 6As shown, it includes a base 1, a winding assembly for winding the blanket body 5 is installed on the top of the base 1, an abutment plate 8 is welded to the top of the base 1, and a printing plate body 7 is placed on the base 1. A slide assembly is installed on the outer wall of the top of the base 1, a sliding plate 11 is slidably connected to the slide assembly, an elastic element is installed on the sliding plate 11, and a bracket 2 is fixed at the bottom of the elastic element. Pressure rollers 22 are rotatably connected to the inner walls on both sides of the bracket 2.

[0030] When attaching the blanket body 5 to the printing plate body 7, first place the printing plate body 7 on top of the base 1, with the end of the printing plate body 7 abutting against the side of the abutment plate 8 and the side of the printing plate body 7 abutting against the side of the slide assembly, thus ensuring the stability and positioning of the printing plate body 7. Next, after applying adhesive to the surface of the printing plate body 7, unwind the blanket body 5 using the winding assembly, aligning the end of the blanket body 5 with the side of the abutment plate 8. The height of the abutment plate 8 is higher than the height of the printing plate body 7. After aligning the end of the blanket body 5 with the side of the abutment plate 8, attach it to the upper surface of one end of the printing plate body 7. The sliding plate 11 is slid along the slide rail assembly. During the sliding process, the sliding plate 11 drives the pressure roller 22 to move. The elastic force of the elastic element makes the pressure roller 22 press tightly against the top of the blanket body 5. The sliding plate 11 continues to slide along the slide rail assembly. As the pressure roller 22 rolls along the top of the blanket body 5, it tightly adheres the blanket body 5 to the top of the printing plate body 7, ensuring flatness of the adhesion. When the blanket body 5 is completely adhered to the top of the printing plate body 7, the blanket body 5 adhered to the printing plate body 7 and the remaining blanket body 5 on the winding assembly are cut off using scissors or other cutting tools to separate the two.

[0031] The slide assembly includes a slide body 4 and a guide plate 12. The slide body 4 is fixed to the top outer wall of the base 1 by bolts, and the guide plate 12 is fixed to the inner walls on both sides of the slide body 4 by screws. The guide plate 12 and the sliding plate 11 are slidably connected.

[0032] The guide plate 12 guides the movement path of the sliding plate 11, so that the pressure roller 22 rolls along the top of the blanket body 5 and attaches the blanket body 5 to the top of the printing plate body 7.

[0033] The elastic element includes a spring 18 and a T-shaped rod 19. The T-shaped rod 19 is slidably connected to the inner wall of the through hole opened on the surface of the sliding plate 11. The bottom of the T-shaped rod 19 is fixedly connected to the top of the bracket 2. The spring 18 is sleeved on the outer wall of the T-shaped rod 19, and the two ends of the spring 18 are respectively fixed to the top outer wall of the sliding plate 11 and the top inner wall of the T-shaped rod 19.

[0034] The elastic force of spring 18 is used to apply a certain pressure between the rubber blanket body 5 and the printing plate body 7 during the pasting process, thereby ensuring the tightness and flatness of the pasting between the rubber blanket body 5 and the printing plate body 7.

[0035] The winding assembly includes a vertical plate 6 and a winding column 14. The vertical plate 6 is fixed to the top outer wall of the base 1 by screws, and the winding column 14 is rotatably connected to the inner wall of the through hole opened on the surface of the vertical plate 6. A chuck 15 is welded to the outer circumference of the winding column 14, and a roll 13 for winding the rubber blanket body 5 is sleeved on the outer wall of the winding column 14. The end of the winding column 14 away from the chuck 15 is connected to a limit plate 9 through an external thread.

[0036] The winding post 14 is provided so that the drum 13 can be installed by means of sleeve connection. The chuck 15 can limit one end of the drum 13. After the drum 13 is sleeved on the outer wall of the winding post 14, the limiting plate 9 and the winding post 14 are threaded together. The limiting plate 9 can limit the other end of the drum 13, thereby ensuring the stability of the drum 13.

[0037] A connecting plate 16 is welded to one side of the outer wall of the sliding plate 11. A guide rod 20 is slidably connected to the through hole on the surface of the connecting plate 16. The bottom of the guide rod 20 is fixed to the mounting plate 10 by screws. A pressure plate 21 is fixed to the bottom of the mounting plate 10. A threaded rod 17 is rotatably connected to the top of the mounting plate 10. The threaded rod 17 and the connecting plate 16 are threaded together.

[0038] During the application process, the rubber blanket body 5 needs to be positioned between one end of the rubber blanket body 5 and one end of the printing plate body 7. That is, the end portion of the rubber blanket body 5 needs to be pre-attached to one end of the rubber blanket body 5 to position the rubber blanket body 5 and the printing plate body 7, so as to avoid the rubber blanket body 5 being misaligned when it is applied to the printing plate body 7. After positioning, the pressure roller 22 is used to roll along the surface of the rubber blanket body 5 to apply the rubber blanket body 5 to the printing plate body 7. Therefore, after the rubber blanket body 5 and the printing plate body 7 are positioned, the threaded rod 17 is rotated, so that the mounting plate 10 and the pressure plate 21 move downward under the guidance of the guide rod 20. The pressure plate 21 is used to press down and smooth the part of the rubber blanket body 5 that plays a positioning role. After pressing down and smoothing, the threaded rod 17 is rotated in the opposite direction to separate the pressure plate 21 from the rubber blanket body 5. Then, the pressure roller 22 is used to apply the remaining rubber blanket body 5 to the printing plate body 7 by rolling.

[0039] A handle 3 is welded to the top outer wall of the sliding plate 11;

[0040] The handle 3 facilitates the control of the sliding plate 11 as it slides along the slide assembly.

[0041] Working principle: First, place the printing plate body 7 on top of the base 1 so that one end abuts against the side of the contact plate 8, and place the side of the printing plate body 7 against the side of the slide assembly for positioning. Then, apply adhesive to the surface of the printing plate body 7. Then, attach the roll 13 with the blanket body 5 wound on it to the winding post 14 of the winding assembly. Use the chuck 15 and the limiting plate 9 to limit the two ends of the roll 13. Then, unwind the roll 13 and place one end of the blanket body 5 against the side of the contact plate 8, which is higher than the printing plate body 7, and then attach it to the top of one end of the printing plate body 7. Then, rotate the threaded rod 17 threaded on the connecting plate 16 on one side of the sliding plate 11 so that the mounting plate 10 and the pressure plate 21 move downward under the guidance of the guide rod 20. The pressure plate 21 is used to press down and smooth the blanket body 5, which plays a positioning role. Then, the threaded rod 17 is rotated in the opposite direction to disengage the pressure plate 21 from the blanket body 5. After that, the handle 3 at the top of the sliding plate 11 is held and pushed to slide the sliding plate 11 along the slide assembly. During the sliding process, the elastic force of the spring 18 of the elastic element causes the pressure roller 22, which is rotatably connected to the inner walls on both sides of the bracket 2, to press tightly against the top of the blanket body 5. The pressure roller 22 rolls along the top of the blanket body 5 to tightly adhere it to the top of the printing plate body 7, ensuring flatness. After the blanket body 5 is completely adhered to the top of the printing plate body 7, the blanket body 5 adhered to the printing plate body 7 and the remaining blanket body 5 on the winding assembly are cut off with scissors or other cutting tools.
