Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing equipment, in particular to a self-locking mechanism of elastic floating clamping. BACKGROUND

[0002] The adoption of multi-layer laminating technology in printing equipment can improve the comprehensive performance and effect of printed matter, especially in terms of functionality, durability, visual effect, etc. When laminating multiple layers, two or more layers of film material are combined into a multi-layer structure through physical or chemical means. Common multi-layer laminating includes hot pressing, which combines films through heating and pressure, commonly used for the lamination of thermoplastic materials.

[0003] Among them, the hot pressing process is to lay the material, then heat the system, use hydraulic or servo motor to drive the pressure roller / pressure plate, uniformly apply pressure, discharge interlayer bubbles and enhance the bonding force. In this process, constant pressure needs to be controlled. When the pressure is too large, the interlayer bubbles remain and the porosity increases. When the pressure exceeds the critical value, the air between the material layers cannot be effectively discharged, but is compressed to form micro-bubbles. In interlayer hot pressing, excessive pressure can cause the glue penetration path to be blocked, bubbles to be retained and cavities to be formed. It can also cause material deformation and surface wrinkles. When the pressure is too small, the material bonding force is insufficient, resulting in delamination defects. Therefore, it is necessary to dynamically adjust the pressure in printing, and the pressure needs to be stable. SUMMARY

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0036] Please refer to Figures 1-8 , the present application provides a technical solution: in the printing industry, in order to improve the quality of some printed materials need to be stacked in multiple layers, multiple layers of stacked materials through structure optimization and function integration, significantly improve the accuracy, durability and visual effect of printed matter, but there are still some problems in the process of multi-layer superposition. Based on this, a kind of elastic floating clamping self locking mechanism is proposed, as Figure 1 shown, including body 1, its inner side is installed with two opposite inner plates 2, as Figure 2 shown, also includes:

[0037] A plurality of transmission shafts 4 are rotatably installed between the two inner plates 2, for supporting the wound material;

[0038] Hot-pressing shaft 5 is rotatably installed between the two inner plates 2;

[0039] Pressure control part 6, as Figure 4As shown, including the rotation in the two inner plate 2 between the inner support shaft 61 and the outer side of the capsule ring 62, 62 and hot pressing shaft 5 will be hot pressing multi-layer material, such as Figure 3 As shown in the material movement diagram, the material is extruded by the capsule ring 62 and the hot pressing shaft 5;

[0040] The floating device 8 and the floating device 9 are symmetrically arranged and respectively mounted on the two inner plates 2 for clamping the pressure control part 6. One side of the floating device 8 and the floating device 9 can be air inlet, and the other side is closed, and the extrusion state of the pressure control part 6 is adjusted.

[0041] Two groups of connecting parts 7 are respectively connected at both ends of the pressure control part 6. The outer sides of the two groups of connecting parts 7 are respectively connected with the floating device 8 and the floating device 9, so that the floating device 8 and the floating device 9 are in communication with the inside of the rotatable pressure control part 6.

[0042] Specifically, the hot pressing shaft 5 can generate heat, and the machine body 1 provides power to improve the effect of hot pressing. The materials on the plurality of transmission shafts 4 realize the effect of superposition when being transmitted to the hot pressing shaft 5. Secondly, the superposition is realized under the combined extrusion of the pressure control part 6 and the hot pressing shaft 5. The inside of the capsule ring 62, the floating device 8 and the floating device 9 uses common gas, and the gas pressure is changed synchronously. When the gas pressure of the capsule ring 62 increases, the gas pressure of the floating device 8 and the floating device 9 also increases, and the downward extrusion of the capsule ring 62 increases, and the extrusion is increased. When the gas pressure is reduced, the gas pressure of the capsule ring 62, the floating device 8 and the floating device 9 is reduced synchronously, and the two are cooperated to realize a flexible change. The outer surface of the capsule ring 62 is more easy to fit the micro profile of the superposed material, so as to avoid the local pressure concentration caused by the surface indentation or wrinkle of the material under the action of pressure.

When the gas pressure is small, the contact area between the capsule ring 62 and the material is large, the unit extrusion force is small, and the unit area pressure is reduced. Only the size of the gas pressure needs to be controlled, which is convenient to operate.

[0051] Specifically, the two groups of holders 83 in the metal frame 81 limit the inner support shaft 61 to realize the up-down adjustment

[0052] The pneumatic telescopic shaft comprises a sleeve one 86 and a sleeve two 87 which are sleeved with each other, one end of the sleeve one 86 and the sleeve two 87 is fixed with the holder 83, and the other end is fixed with the inner wall of the metal frame 81.

[0056] Specifically, the air pressure in the capsule ring 62 is detected, which can be directly displayed, and the air pump can also be adjusted by the controller to ensure that it is under the appropriate air pressure.

[0057] The working principle of the present application is that a plurality of groups of materials are wound on respective transmission shafts 4, and are laminated between the hot pressing shaft 5 and the pressure control part 6, and the laminated materials are pressed by the hot pressing shaft 5 and the pressure control part 6 to realize the lamination of the materials.
