In the running process of the device, the heating roller 3 and the pressing plate 5 need to be moved and positioned on the supporting plate 2, and the supporting plate 2 can provide enough support and stability, so that the movement track of the heating roller 3 and the pressing plate 5 is ensured to be accurate, and the precision and the stability of the processing process are ensured. During the pressing process, the heating roller 3 and the pressing plate 5 need to withstand a certain pressure and load. The support plate 2 can uniformly distribute these pressures and loads, avoid deformation or damage of the device due to pressure unevenness, and simultaneously ensure stable movement and pressing effect of the heating roller 3 and the pressing plate 5. Meanwhile, the supporting plate 2 is used as a component part of the whole device, and the heating roller 3, the pressing plate 5 and other functional components can be organically integrated together to form a stable structure. The backup pad 2 is provided with the heating roller 3 that is the cylinder shape from top to bottom symmetry, and the heating roller 3 of cylinder shape can ensure that label leatheroid obtains even heating in the pressfitting process. Since the heating roller 3 is cylindrical, the contact area between the surface of the heating roller and the label sheet is relatively uniform, and heat can be more uniformly conducted to the surface of the label sheet, thereby ensuring uniformity and consistency of heating. And the cylindrical heating roller 3 is more flexible in design and is suitable for label leathers with different shapes and sizes. The cylindrical heating roller 3 can provide good adaptability regardless of the planar or curved label sheet, ensuring the stability and effect of the pressing process. While the cylindrical heating roller 3 is simpler in structure than other heating elements. Therefore, the manufacturing cost can be reduced, the reliability and stability of the device are improved, the occurrence rate of faults is reduced, and meanwhile, the maintenance and the maintenance are easier. The pressed label paper sheets are arranged between the heating rollers 3 which are vertically symmetrical, the inside of the heating rollers 3 is provided with the cavity 4 which is made of flexible materials, and the cavity 4 can lighten the whole weight of the device, so that the device is easier to move, install and operate. Particularly in the case where frequent movement or adjustment of the position is required, the lightweight design can improve the operation efficiency and convenience. Referring to fig. 5 and 9, a pressing plate 5 is disposed inside the cavity 4, and a heating module is disposed inside the pressing plate 5, so that the design of the pressing plate 5 can ensure that enough pressure is applied to the label paper sheet in the processing process, thereby realizing the pressing effect. Referring to fig. 1, 7, 8 and 9, connecting rods 9 are disposed at two ends of the heating module, and the connecting rods 9 penetrate through the heating roller 3 and are disposed at the outer sides thereof, so that the connecting rods 9 can be used for communicating with the internal power supply of the heating module. The two ends of the heating roller 3 are provided with driving components for driving the heating roller to rotate and slide up and down along the supporting plate 2; referring to fig. 5 and 6, when the upper and lower heating rollers 3 are close to each other, the upper and lower pressing plates 5 press each other, so that the upper and lower heating rollers 3 are deformed by pressing each other and the contact surfaces thereof are changed into planes, as shown in fig. 6. The drive assembly includes rotation motor 6, lifter plate 7, lifting module 8, fixed connection between rotation motor 6's the motor shaft and the heating roller 3, rotation motor 6 is fixed to be set up on lifter plate 7, and lifter plate 7 assembles on lifting module 8. The lifting module 8 is fixedly arranged on the supporting plate 2. The lifting plate 7 can be driven to move up and down by the lifting module 8.

Referring to fig. 5, 7, 8 and 9, the two ends of the heating roller 3 are further provided with a plurality of ventilation holes, and the ventilation holes are provided with an air pump 10 for controlling the air quantity in the cavity 4, and in the working process, the total air quantity in the heating roller 3 is regulated by the air pump 10, so that the deformation and pressure of the heating roller 3 can be accurately controlled to adapt to different material and thickness requirements. Referring to fig. 1, the support plate 2 is provided with sliding grooves 11 symmetrically up and down, two ends of the heating roller 3 are slidably disposed in the sliding grooves 11, and the sliding grooves 11 can limit the sliding range of the heating roller 3. Referring to fig. 5 and 6, the length of the cross section of the pressing plate 5 is smaller than the inner diameter of the heating roller 3, so that a gap is left between the pressing plate 5 and the heating roller 3, and the gas circulation efficiency inside the cavity 4 is improved. The heating roller 3 is made of heat-resistant flexible material. Referring to fig. 1, the lifting module 8 adopts a screw structure. The two sides of the heating roller 3 are also provided with driving rollers 12.

When the device is used, the driving roller 12 on one side is provided with the label paper sheets which are not pressed, the driving roller 12 on the other side collects the label paper sheets which are pressed, and the air pump 10 inflates the heating pipe. When the label paper sheet which is not pressed is preliminarily pressed by the heating roller 3 when passing through the upper and lower heating rollers 3, as shown in fig. 5, after the heating roller 3 rolls by a distance of one half of the section of the pressing plate 5, the upper and lower lifting plates 7 drive the heating roller 3 to leave the surface of the label paper sheet, and then the motor 6 is rotated to drive the heating roller 3 to rotate until the pressing plate 5 is parallel to the label paper sheet. The heating roller 3 is driven by the up-down lifting plate 7 to indirectly press the label paper sheet by the pressing plate 5, the surface temperature of the heating roller 3 contacting with the pressing plate 5 rises due to the heating module arranged inside the pressing plate 5, and the heating roller 3 is made of heat-resistant flexible materials, the upper pressing plate 5 and the lower pressing plate 5 are mutually close to each other to press the heating roller 3 and enable the surface of the heating roller 3 to be gradually attached to the surface of the pressing plate 5 to be a plane, and when the upper pressing plate 5 and the lower pressing plate 5 are completely pressed, the surface of the upper heating roller 3 and the surface of the lower heating roller 3 are also completely attached to the label paper sheet, and at the moment, the upper surface and the lower surface of the label paper sheet are subjected to the up-down pressure of the high-temperature heating roller 3 and the pressing plate 5 to carry out a pressing procedure as shown in fig. 6. The device combines the original two independent steps into one by integrating the preliminary pre-pressing and complete pressing procedures in the label paper sheet pressing process, thereby reducing the complexity of the device and the number of required parts. By performing both procedures in one configuration, the volume of the device is greatly reduced, as the functions of the entire device are compactly integrated, making it more suitable for use in applications where space is limited or frequent movement is required.

In the course of working, because the pressure plate 5 can heat the gas in the cavity 4 to indirectly heat the surface of the heating roller 3, thereby realize just can preheat the label leatheroid in preliminary pressfitting in-process, can reduce required heat in the follow-up heating process, this kind of preheating can make the label leatheroid reach higher temperature when getting into the pressfitting link, process time is shorter, production efficiency is higher, and this kind of heating is because heating the surface of the heating roller 3 through surrounding gas, the heating effect is more even, compare the inhomogeneous problem of heating that probably exists in the traditional structure, this kind of structure can guarantee the temperature homogeneity in the course of working better, processingquality and stability have been improved.

In the laminating process of the device, the pressure in the cavity 4 can be adjusted by adjusting the total amount of gas in the heating roller 3 through the air pump 10, so that the pressure in the preliminary pre-laminating process is adjusted, the deformation degree and the pressure of the heating roller 3 can be very accurately controlled by adjusting the internal gas amount, the control mode can be quickly adjusted according to different material and thickness requirements, compared with the traditional mechanical adjusting mode, the air pressure adjustment can be more flexible and quicker to meet the changing requirements on the production line, and the gas is used as an adjusting medium, so that the abrasion is small and the failure rate is low compared with a mechanical adjusting element. This design reduces wear and potential maintenance of the mechanical components, reducing the cost of long-term operation. And the contact area between the heating roller 3 and the label paper can be indirectly adjusted by changing the pressure in the cavity 4, and the internal pressure of the heating roller 3 can be controlled by inflating or releasing gas into the internal cavity 4 of the heating roller 3 through the air pump 10. Increasing the air pressure expands the heating roller 3, thereby reducing the contact area with the label sheet; reducing the air pressure causes the heated roller 3 to partially collapse, increasing the contact area with the label web. Thereby realizing the change of the preliminary pre-pressing area, and when the preliminary pre-pressing pressure or the contact area with the label paper needs to be changed, the adjustment of the gas pressure in the cavity 4 can be realized. This is because the shape and size of the heating roller 3 directly affect the contact with the label sheet. If a more uniform or wider contact is required to increase heating efficiency or improve press-fit effect, the contact area can be enlarged by reducing the internal air pressure. Conversely, if it is desired to reduce the contact area to suit a particular processing requirement or to avoid excessive lamination, the internal air pressure may be increased. Meanwhile, in the process of pressing the upper and lower pressing plates 5, the air pump 10 can release the pressure in the air stabilizing cavity 4 in the cavity 4 to prevent potential safety hazards.
