Description

Technical Field

[0001] The invention relates to the technical field of printing equipment, in particular to an elastic floating clamping self-locking mechanism. Background Art

[0002] The use of multi-layer lamination technology in printing equipment can enhance the overall performance and effectiveness of printed products, particularly in terms of functionality, durability, and visual quality. Multi-layer lamination typically involves physically or chemically combining two or more layers of film material into a multi-layer structure. Common multi-layer lamination methods include heat pressing, which uses heat and pressure to bond the films and is often used for laminating thermoplastic materials.

[0003] The hot pressing process involves laying the material, then heating it with a heating system. A hydraulic or servo motor drives the pressure roller / platen to apply uniform pressure, expel air bubbles between layers, and enhance bonding strength. During this process, constant pressure must be maintained. When the pressure is too high, air bubbles remain between layers and the porosity increases. When the pressure exceeds a critical value, the air between the material layers cannot be effectively expelled and is instead compressed to form microbubbles. During interlayer hot pressing, excessive pressure can obstruct the glue penetration path, trapping air bubbles and forming cavities. This can also cause material deformation and surface wrinkles. When the pressure is too low, insufficient bonding between the materials leads to delamination defects. Therefore, dynamic pressure adjustment is required during printing, and the pressure must be stable. Summary of the Invention

[0011] Furthermore, a supporting beam is fixed between the two inner plates.

[0012] Furthermore, the bag ring is made of rubber material, and can produce fitting deformation when the outer side is subjected to force.

[0014] The first floating device and the second floating device both include a metal frame, a clamp and a pneumatic telescopic shaft. The buckle ring is connected to the pneumatic telescopic shaft. Under changes in air pressure, the pneumatic telescopic shaft realizes telescopic changes and changes in air pressure inside the bag ring.

[0015] Furthermore, the outer closing ring and the inner closing ring are integrally formed with buckling edges near the edges, and two circles of sealing grooves are fixed on one side of the buckling ring. The two circles of sealing grooves are respectively matched with the two buckling edges, and the buckling ring and the inner closing ring are detachably fixed.

[0016] Furthermore, the metal frame is fixed to the inner plate, the metal frame is hollowed out, and longitudinal limit paths are opened on both sides thereof. The clamps are provided with two groups located inside the metal frame, and the two groups of clamps are arranged up and down to clamp the end of the inner support shaft. The outer sides of the two groups of clamps are integrally provided with an extension end extending into the limit path, and the outer sides of the two groups of extension ends are fixed with limit plates, so that the inner support shaft can move up and down in the metal frame.

[0017] Furthermore, the pneumatic telescopic shaft includes a sleeve 1 and a sleeve 2 which are sleeved together, one end of the sleeve 1 and the sleeve 2 is fixed to the clamp, and the other end is fixed to the inner wall of the metal frame;

[0018] The outer ends of sleeve one and sleeve two are respectively fixed with pipe mouth one and pipe mouth two, and the outer side of the buckling ring is integrated with an air inlet hole, and the air inlet hole is connected with the inside of the bag ring, wherein the pipe mouth one of the floating device one and the floating device two are respectively connected with the air inlet holes on both sides, the pipe mouth two of the floating device one is connected to the air inlet pipe, and the air inlet pipe is connected to the air pump, and the pipe mouth two of the floating device two is blocked with a plug.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the linkage between the air pump and the bladder ring, the pressure can be increased or decreased in real time during the hot pressing process, solving the problem of interlayer bubble retention or insufficient bonding force caused by traditional fixed pressure. Floating device 1 and floating device 2 are linked with the bladder ring. When the air pressure inside the bladder ring is high, the downward pushing force of floating device 1 and floating device 2 is also strong. When the air pressure in the bladder ring gradually decreases, the downward pushing force of floating device 1 and floating device 2 also gradually decreases, realizing dynamic pressure adaptive adjustment. When encountering materials of different thicknesses, the air pressure controls the bladder ring, floating device 1 and floating device 2, which has a buffering effect to avoid material damage, realize elastic floating clamping effect, and form a self-locking force for material extrusion under the action of air pressure.

[0022] 2. The rubber material of the capsule ring presents an elastic deformation gradient under changes in air pressure.

[0023] 3. By setting different air pressure parameters through the controller, it can adapt to the various lamination requirements of different composite materials and solve the problem that traditional hot pressing process is difficult to adapt.

[0024] 4. Floating device 1 and floating device 2 are symmetrically distributed, cooperating with the synchronous movement of the limit track and the clamp to ensure balanced force on both ends of the inner support shaft, avoiding material deviation or eccentric wear of the hot pressing shaft caused by unilateral pressure overload.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-8 The present invention provides a technical solution: In the printing industry, in order to improve the quality of some printed materials, multiple layers of materials need to be laminated. Multi-layer laminated materials have significantly improved the accuracy, durability and visual effects of printed products through structural optimization and functional integration. However, there are still some problems in the multi-layer lamination process. Based on this, an elastic floating clamping self-locking mechanism is proposed, such as Figure 1 As shown, it includes a body 1, on the inner side of which are mounted two opposite inner panels 2, as shown in FIG. Figure 2 As shown, it also includes:

[0037] Multiple sets of transmission shafts 4 are rotatably mounted between the two inner plates 2 to support the wound material;

[0038] The hot pressing shaft 5 is rotatably mounted between the two inner plates 2;

[0039] Pressure control unit 6, such as Figure 4As shown, it includes an inner support shaft 61 rotating between two inner plates 2 and a capsule ring 62 wrapped around the outer side of the inner support shaft 61. The capsule ring 62 and the hot pressing shaft 5 heat press the multi-layer material, as shown in FIG. Figure 3 The figure shows the movement of the material, in which the material is squeezed by the capsule ring 62 and the hot pressing shaft 5;

[0040] The first floating device 8 and the second floating device 9 are symmetrically arranged and respectively installed on the two inner plates 2, and are used to clamp the pressure control part 6. One side of the first floating device 8 and the second floating device 9 can be air-intake, and the other side is closed to adjust the extrusion state of the pressure control part 6;

[0041] The two sets of connecting parts 7 are respectively connected to the two ends of the pressure control part 6. The outer sides of the two sets of connecting parts 7 are respectively connected to the floating device 1 8 and the floating device 2 9, so that the floating device 1 8 and the floating device 2 9 are connected to the interior of the rotatable pressure control part 6.

[0042] Specifically, the hot pressing shaft 5 can generate heat and provide electricity through the body 1 to improve the effect of hot pressing. When the materials on the multiple transmission shafts 4 are transferred to the hot pressing shaft 5, they are superimposed. Secondly, the superposition is achieved under the joint extrusion of the pressure control unit 6 and the hot pressing shaft 5. The bag ring 62, the floating device 1 8, and the floating device 2 9 use a common gas inside, and the air pressure is changed synchronously. When the air pressure in the bag ring 62 increases, the air pressure in the floating device 1 8 and the floating device 2 9 also increases, increasing the downward extrusion of the bag ring 62. When the air pressure decreases, the bag ring 62, the floating device 1 8, and the floating device 2 9 simultaneously reduce the air pressure. The two work together to achieve a flexible change. The outer surface of the bag ring 62 is more easily fitted to the micro-contours of the superimposed materials, thereby avoiding indentations or wrinkles on the material surface caused by local pressure concentration under the action of pressure.

[0043] A supporting crossbeam 3 is fixed between the two inner panels 2 to reinforce the inner panels 2 on both sides.

[0044] The bag ring 62 is made of rubber. When the outer side is subjected to force, it can produce fitting deformation and can change the air pressure according to the overlapping materials. When the air pressure is high, the area of the bag ring 62 fitting with the material is small, the extrusion force is large, and the pressure per unit area is also increased. When the air pressure is low, the area of the bag ring 62 fitting with the material is large, the unit extrusion force is small, and the pressure per unit area is reduced. It is only necessary to control the size of the air pressure for easy operation.

[0045] like Figure 5 and Figure 6The figure shows the structure of the connecting portion 7. The connecting portion 7 includes an outer closed ring 71 and an inner closed ring 72. The axes of the outer closed ring 71 and the inner closed ring 72 coincide with the inner support shaft 61. The edge of the bag ring 62 is fixed to the outer closed ring 71. The inner closed ring 72 is fixedly sleeved on the inner support shaft 61. The outer closed ring 71 and the inner closed ring 72 are sleeved together. An annular air intake cavity 73 is formed between the outer closed ring 71 and the inner closed ring 72. The outer cover of the air intake cavity 73 is provided with a snap ring 75.

[0046] like Figure 7 As shown, both the floating device 1 8 and the floating device 2 9 include a metal frame 81, a clamp 83 and a pneumatic telescopic shaft. The buckle ring 75 is connected to the pneumatic telescopic shaft. Under the change of air pressure, the pneumatic telescopic shaft realizes telescopic change and the air pressure inside the bag ring 62 changes.

[0047] Specifically, the buckle ring 75 is fixed to the inner closed ring 72 so that the buckle ring 75 remains fixed, while the bag ring 62 can rotate with the outer closed ring 71 , and the gas can also move from the air inlet cavity 73 into the bag ring 62 .

[0048] The outer sealing ring 71 and the inner sealing ring 72 are integrally formed with a buckling edge 74 near the edges of each other, and two circles of sealing grooves 76 are fixed on one side of the buckling ring 75. The two circles of sealing grooves 76 respectively cooperate with the two buckling edges 74, and the buckling ring 75 and the inner sealing ring 72 are detachably fixed.

[0049] Specifically, there are sealing rings in the two sealing grooves 76 of the buckling ring 75, and the two sealing grooves 76 clamp the buckling edge 74 to achieve relative sealing and prevent the internal gas from moving outward. It should be noted that the buckling ring 75, the outer sealing ring 71 and the inner sealing ring 72 can be replaced by other rotatable connecting parts by those skilled in the art.

[0050] The metal frame 81 is fixed to the inner plate 2. The metal frame 81 is hollowed out and has longitudinal limiting paths 82 on both sides. There are two groups of clamps 83 located inside the metal frame 81. The two groups of clamps 83 are arranged up and down to clamp the end of the inner support shaft 61. The outer sides of the two groups of clamps 83 are integrally provided with extension ends 84 extending into the limiting paths 82. The outer sides of the two groups of extension ends 84 are fixed with limiting plates 85, so that the inner support shaft 61 can move up and down in the metal frame 81.

[0051] Specifically, the two sets of clamps 83 in the metal frame 81 limit the inner support shaft 61 to achieve the adjustment in the up and down directions.

[0052] The pneumatic telescopic shaft includes a sleeve 1 86 and a sleeve 2 87 which are connected to each other. One end of the sleeve 1 86 and the sleeve 2 87 is fixed to the clamp 83, and the other end is fixed to the inner wall of the metal frame 81.

[0053] The outer ends of sleeve 1 86 and sleeve 2 87 are respectively fixed with a pipe opening 1 861 and a pipe opening 2 871. The outer side of the buckle ring 75 is integrally provided with an air inlet 77, and the air inlet 77 is connected to the interior of the bag ring 62. The pipe opening 1 861 of the floating device 1 8 and the floating device 2 9 are respectively connected to the air inlet 77 on both sides, and the pipe opening 2 871 of the floating device 1 8 is connected to the air inlet pipe 872, and the air inlet pipe 872 is connected to the air pump. Figure 8 As shown, a plug 873 is blocked in the pipe opening 871 of the second floating device 9.

[0054] Specifically, the pneumatic telescopic shaft comprises a sleeve 1 86 and a sleeve 2 87 that are interconnected. The downward force exerted by the two sets of grippers 83 is controlled by the air pressure, enabling more precise control. Furthermore, the air can be compressed, giving the pneumatic telescopic shaft an elastic expansion and contraction effect. When compressing laminated materials of varying thickness, the pneumatic telescopic shaft can produce an elastic floating effect. While the effect is similar to that of a spring, springs are prone to fatigue, while pneumatic telescopic shafts do not. The plug 873 serves to close the floating device 1 8, the floating device 2 9, and the intermediate bag ring 62, leaving only a single air inlet. It should be noted that the air pump achieves inflation, and while there is a certain potential for leakage of the blown air, this allows for continuous inflation and pressure maintenance.

[0055] An air pressure sensor 63 is fixed to the outer wall of the inner support shaft 61 , and a controller is also installed inside the body 1 . The air pressure sensor 63 and the air pump are electrically connected to the controller, and the air pressure sensor 63 controls the working state of the air pump.

[0056] Specifically, by detecting the air pressure inside the bag ring 62, it can be displayed intuitively, and at the same time, the air pump can be adjusted through the controller to ensure that it is at an appropriate air pressure.

[0057] The working principle of the present invention is as follows: multiple groups of materials are wound on their respective transmission shafts 4, and are passed between the hot pressing shaft 5 and the pressure control part 6 for overlap, and the overlapping of the materials is achieved under the extrusion action of the hot pressing shaft 5 and the pressure control part 6 on the multiple groups of materials.

[0058] The multiple layers of material are wound onto the conveyor shaft 4, guided, and then overlapped and passed through the gap between the hot pressing shaft 5 and the pressure control unit 6. The conveyor shaft 4 rotates to ensure smooth material delivery. The air pump is activated, and gas is injected into the second nozzle 871 of the floating device 1 8 through the air inlet pipe 872. Because the second nozzle 871 of the floating device 2 9 is sealed by a plug 873, the gas flows unidirectionally into the air inlet cavity 73 of the connecting portion 7, ultimately entering the interior of the bag ring 62.

[0059] In the high-pressure state, when the air pump increases the pressure, the air pressure inside the bag ring 62 increases, the expansion and deformation ability of the rubber material decreases, and the pneumatic telescopic shaft is pushed downward by the air pressure. The pressure control part 6 and the hot pressing shaft 5 apply a rigid clamping force to the material to ensure a tight fit between the layers.

[0060] In the low-pressure state, when the air pump decompresses, the air pressure inside the bag ring 62 decreases, the rubber recovers its elastic deformation ability, the pneumatic telescopic shaft contracts, and the clamping force of the pressure control part 6 on the material is weakened, adapting to the stacking of materials of different materials.

[0061] In addition, the air pressure sensor 63 monitors the internal pressure of the bag ring 62 in real time and feeds the data back to the controller to achieve precise control in high pressure or low pressure state, which can be used for laminated materials of different materials.

[0062] Floating device 1 8 and floating device 2 9 constrain the vertical displacement of inner support shaft 61 through symmetrical clamps 83 and limit rails 82. When air pressure changes, extension end 84 slides along limit rails 82, ensuring a stable vertical trajectory of inner support shaft 61 and preventing uneven pressure distribution.
