The description and drawings of the application and the above-described accompanying drawings are intended to cover not only the technical solutions falling within the present application but also technical equivalents or substitutes for them.

[0025] In order to solve the problem that the fine waste leather produced in the embossing process of the PU synthetic leather is easily sucked into the body and harms the health of the body in the related art, the embodiments of the present application provide the following solutions.

[0026] Please refer to Figures 1-5 , including a rack 1, an embossing mechanism 2, and a dust removal mechanism 5, the dust removal mechanism 5 includes a working box 54, a lifting glass 51, an electric push cylinder 52 and a dust collector 53, the working box 54 is fixedly connected to the rack 1, the working box 54 is provided with a groove, the electric push cylinder 52 is arranged in the groove, the lifting glass 51 is arranged on the electric push cylinder 52 and is in sliding connection with the working box 54, the working box 54 is also provided with a ventilation hole 8, the ventilation hole 8 is in communication with the dust collector 53, the embossing mechanism 2 is arranged on the rack 1, and the embossing mechanism 2 is used for printing synthetic leather.

[0027] In this way, when the staff performs the embossing operation on the PU synthetic leather, the PU synthetic leather is sent into the box through the embossing mechanism 2, the electric push cylinder 52 drives the lifting glass 51 to move downward, the dust collector 53 is turned on after the embossing mechanism 2 completes the embossing on the PU synthetic leather, according to Bernoulli's principle, the decrease of the lifting glass 51 makes the ventilation hole smaller, and the ventilation hole 8 connected with the dust collector 53 generates a stronger suction force, thereby sucking away the debris generated in the embossing process, and also sucking away the volatile organic compounds generated in the embossing process, meanwhile, the dust collector 53 is internally provided with a filter membrane and an activated carbon adsorption package, the filter membrane is used for separating the debris from the volatile organic compounds, the debris cannot pass through the filter device, and the volatile organic compounds passing through the filter membrane are adsorbed by the activated carbon adsorption package, so that they cannot be dispersed, thereby ensuring a green and safe working environment.

[0028] Optionally, in some embodiments, please refer to Figure 1 , the end of the lifting glass 51 away from the electric push cylinder 52 is bonded with a rubber gasket 6.

[0029] In this way, the rubber ring 6 can prevent the glass body from being bumped during the lowering of the lifting glass 51, and has a protective effect on the lifting glass 51, and also has a limiting effect.

[0030] Optionally, in some embodiments, referring to Figures 1-3 , the embossing mechanism 2 comprises a pressing plate 21, a pressing rod 22, a die plate 23, a placing plate 25 and a driving assembly 24, the driving assembly 24 is arranged on the rack 1, the pressing rod 22 is slidingly connected to the working box 54, the pressing plate 21 is fixedly connected to one end of the pressing rod 22 away from the working box 54, the die plate 23 is movably connected to the pressing plate 21, and the driving assembly 24 is drivingly connected to the placing plate 25.

[0031] In this way, after the PU synthetic leather is placed on the placing plate 25, the driving assembly 24 slides the placing plate 25 into the working box 54, the pressing rod 22 vertically downward, the pressing rod 22 can enhance and reduce the pressure caused by the die plate 23, drives the pressing plate 21 and the die plate 23 to move downward, the die plate 23 is in contact with the surface of the PU synthetic leather, the pressing plate 21 generates a high-frequency electromagnetic wave current electric field instantaneously, the electromagnetic wave is transmitted to the surface of the PU synthetic leather material through the heating coil and the die plate 23, the internal molecules of the PU synthetic leather begin to polarize and rub under the action of the electromagnetic wave, the internal molecule friction is converted into heat energy, and the eddy current generated by the die plate 23 generates Joule heat on the internal resistance of the PU synthetic leather, and the two work together to rapidly heat the synthetic leather material. During the heating process, the pressing rod 22 exerts pressure downward, so that the die plate 23 exerts pressure on the leather, so that the PU synthetic leather material deforms under the combined action of heat and pressure, and as the temperature rises and the pressure continues to be applied, the material achieves the effect of branding, welding and sealing. The pattern and texture of the die are clearly embossed on the PU synthetic leather, after the embossing is completed, the pressing rod 22 drives the pressing plate 21 and the die plate 23 to move upward, the PU synthetic leather gradually cools and solidifies in the box, maintains the stability and durability of the embossed pattern, and the die plate 23 is detachable, and different die plates 23 can be replaced according to the requirements of the embossed pattern.

[0032] Optionally, in some embodiments, referring to Figure 2The driving assembly 24 comprises a rotating motor 241, a rotating shaft 242, a connecting rod 243, a first sliding block 244, a sliding shaft 245, a sliding rail 246 and a second sliding block 247. The sliding rail 246 and the rotating motor 241 are fixedly connected to the rack 1. The sliding rail 246 is provided with a sliding groove. The second sliding block 247 is slidably connected to the sliding rail 246 through the sliding groove. The sliding shaft 245 is fixedly connected to the second sliding block 247. The first sliding block 244 is slidably connected to the sliding shaft 245. The rotating shaft 242 is fixedly connected to the first sliding block 244. One end of the connecting rod 243 is fixedly connected to an output end of the rotating motor 241. The other end of the connecting rod 243 is rotatably connected to the first sliding block 244 through the rotating shaft 242. The placing plate 25 is fixedly connected to the second sliding block 247.

[0033] In this way, when the placing plate 25 is driven by the driving assembly 24 to enter or exit the box, when the rotating motor 241 drives the rotating shaft 242 to rotate counterclockwise, since one end of the connecting rod 243 is fixedly connected to the rotating shaft 242 and the other end is rotatably connected to the first sliding block, the connecting rod 243 is driven by the rotating shaft 242 to rotate counterclockwise, and at the same time, the first sliding block is slid leftward along the sliding shaft 245. Since the length of the connecting rod 243 is fixed, the second sliding block 247 is driven to move along the sliding rail 246 in the direction of the box. Since the second sliding block 247 is integrated with the placing plate 25, the placing plate 25 enters the box. When the rotating motor 241 drives the rotating shaft 242 to rotate clockwise, the same principle is realized, and the placing plate 25 exits the box. Since the length of the connecting rod 243 is constant, the connecting rod 243 also functions as a limiting part.

[0034] Optionally, in some embodiments, referring to Figure 1 The rack 1 is further provided with a first control module 3 and a second control module 4. The first control module 3 is electrically connected to the dust collector 53, the pressing plate 21 and the pressing rod 22. The second control module 4 is electrically connected to the rotating motor 241, the electric cylinder 52 and the dust collector 53.

[0035] In this way, the first control module 3 can control the adjustment of the embossing machine body to produce pressure, temperature and time when embossing on the surface of synthetic leather, and control the power of the dust collector 53. The second control module 4 controls the rotation direction of the rotating motor 241 to drive the placement plate 25 in and out of the work tank 54, and can also control the lifting of the lifting glass 51. When the lifting glass 51 is lifted to any position, it stops continuing to lift, continues to operate the second control module 4 to drive the pressure rod 22 to drive the pressure plate 21 and the mold plate 23 to press down, and completes the embossing operation under the set condition. After the control of the pressure rod 22 to drive the pressure plate 21 and the mold plate 23 to reset, the dust collector 53 absorbs the debris, and finally controls the lifting of the lifting glass 51 to rotate the rotating motor 241 clockwise to drive the placement plate 25 and the finished PU synthetic leather to slide out of the work tank 54.

[0036] Optionally, in some embodiments, referring to Figure 3 , the placement plate 25 is also welded with a plurality of cooling fins 7 below.

[0037] In this way, the temperature rises rapidly during embossing work, and the plurality of cooling fins 7 below the placement plate 25 help to dissipate heat into the air to maintain the stability of the temperature of the placement plate 25.

[0038] The above only describes the preferred embodiments of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
