[0003] The heating methods of traditional coating and laminating machines include segmented heating, local heating, centralized heating, and fixed-point heating, etc. However, when the hot-melt material is fully heated, it is easy for the hot-melt material to be overheated and deformed, affecting the uniform lamination. Although segmented heating can alleviate this problem, the thermal interference of each heating chamber is serious, and it is impossible to achieve rapid heating. The temperature control accuracy is poor, and the temperature is easy to disperse. At the same time, after hot-melt composite coating, the coating material of traditional equipment cannot be cooled down in time and effectively, which affects the solidification and condensation speed of the material; due to the slow cooling speed, the production efficiency is greatly restricted and cannot meet the requirements of modern production for high efficiency, and the product quality may be reduced due to untimely cooling. In addition, the segmented heating chamber is poorly sealed, heat is lost a lot, and cold and hot air alternately generate water vapor, causing the heating chamber to be in a humid environment, affecting the heating efficiency and temperature control.

A sliding rod 22 is fixedly connected between the two brackets 21 in a symmetrical structure, and the end of the sliding rod 22 passes through the bracket 21. Annular sliding grooves 23 are respectively provided on the inner walls on both sides of the heating roller 12, and the ends of the two sliding rods 22 are slidably connected inside the annular sliding grooves 23.

[0023] Specifically, the guide grooves 251 are symmetrically distributed with the middle guide groove 251, and each guide groove 251 has a different inclination angle. The heating plate 26 slides in the guide groove 251 through the guide rod 261, so that the heating plates 26 are gathered or spread out at equal distances, thereby achieving both segmented heating and centralized heating of the hot-melt material.

[0024] When in use, the first motor 24 drives the transmission rod 25 to rotate, and the guide rod 261 slides in the guide groove 251, so that the plurality of heating plates 26 are gathered or spread out at equal distances, wherein the plurality of heating plates 26 slide through the upper slide rod 22 to achieve stable translation.

[0025] The present invention drives the transmission rod 25 to rotate, and the heating plate 26 slides in the guide groove 251 through the guide rod 261, so that the heating plates 26 are arranged equidistantly and linearly and concentratedly, further realizing segmented heating and centralized heating.

The walls are symmetrically structured and fixedly connected with sealing plates 33. The interior of every two sealing plates 33 is symmetrically structured and slidably connected with sealing blocks 34. The sealing blocks 34 are slidably adapted to the slide rails 32. The sealing blocks 34 and the slide rails 32 form a circle that is adapted to the surface of the transmission rod 25. The side surfaces of each bracket 21 are symmetrically structured and hinged with a first counterweight 35. The transmission rod 25 is fixedly connected with a ratchet 36 at one end away from the first motor 24, and the ratchet 36 is meshed with the pawl 122. An annular sponge 37 is fixedly connected to both sides of each water-cooling ring 31.

[0027] Specifically, the transmission rod 25 , the heating plate 26 , the water-cooling ring 31 and the heating roller 12 are transversely coaxial, the sealing plate 33 and the sealing block 34 form an annular seal, and the annular seal is sleeved on the surface of the transmission rod 25 .

[0028] During use, when several heating plates 26 are gathered together, the water-cooling ring 31 slides to both sides through the pneumatic slider 311, causing the several heating plates 26 to gather together, so that when the heating plates 26 are heated, the cooling components do not interfere with the heating chamber, thereby achieving a centralized heating effect. When several heating plates 26 are spread out, several water-cooling rings 31 are arranged in a linear array inside the heating roller 12, and the heating plates 26 are arranged between two adjacent water-cooling rings 31, and are meshed and connected with the pawl 122 through the ratchet 36, driving the first motor 24, the transmission rod 25, the bracket 21 and the slide rod 22 to rotate, causing the first counterweight block 35 to rotate axially. At this time, the water-cooling ring 31 rotates, the sealing plate 33 is on top, and the sealing block 34 slides downward by its own weight, so that the annular seal formed by the sealing plate 33 and the sealing block 34 is used to isolate several heating chambers, thereby further realizing segmented heating of the surface of the hot melt adhesive material.

[0032] When in use, after hot-melt compounding, the lower surface of the pressure roller 11 is cooled through the cooling chamber and is brought into rolling contact with the coating after hot-melt compounding, so as to solidify and condense.

[0033] After hot melt composite coating, the coating material of the present invention passes through the composite coating cooling zone 8, and the heat is transferred through the pressure roller 11. A cooling chamber is provided inside the pressure roller 11, and the coolant continuously flows under the action of the water-blocking plate 41, which can effectively reduce the surface temperature of the pressure roller 11, cool the coating, promote the rapid solidification and condensation of the composite material, and ensure product quality.

The inner walls of the machine tool 1 on both sides are respectively fixedly connected with tracks 72, and each track 72 is slidably connected with an axle frame 73. The two ends of the pressure roller 11 are movably connected inside the axle frame 73, and the axle frame 73 is transmission-connected to the hydraulic rod 71.

[0035] When in use, the first unwinding roller 52 is used to unwind the hot melt material, the second unwinding roller 61 is used to unwind the coating, the winding roller 62 is used to wind up the composite coating, and the two hydraulic rods 71 ​​are used to adjust the two shaft frames 73 to further adjust the distance between the pressure roller 11 and the heating roller 12.

[0036] The present invention controls the hydraulic rod 71 through an external control system to push the shaft frame 73 to slide on the track 72, and can accurately adjust the distance between the pressure roller 11 and the heating roller 12 to adapt to hot-melt materials and coating materials of different thicknesses, ensure the stability and uniformity of the composite effect, and meet diverse production needs.

[0037] Working principle: This embodiment provides a coating laminating machine with automatic adjustment of the laminating gap. The gap adjustment is as follows: the hot melt material contacts the first conveying roller set 53 and then contacts the surface of the heating roller 12. The coating material contacts the surface of the pressure roller 11 through the winding roller set 63 and then winds around the surface of the winding roller 62. Figure 5 As shown, the hydraulic rod 71 is operated by an external control system, and the hydraulic rod 71 pushes the shaft frame 73 to slide on the track 72, thereby adjusting the distance between the pressure roller 11 and the heating roller 12; Segmented hot-melt material heating: the first motor 24 is operated through an external circuit mechanism, and the first motor 24 drives the transmission rod 25 to rotate. At this time, the heating plate 26 slides in the guide groove 251 through the guide rod 261, exerting thrust on the plurality of heating plates 26, and the heating plate 26 is limited by one of the slide bars 22, so that the heating plates 26 move equidistantly, thereby making the heating plates 26 arranged in a linear array. At this time, the water-cooling ring 31 uses an external control system to make the pneumatic slider 311 slide on another slide bar 22, and the plurality of water-cooling rings 31 are arranged equidistantly linearly, and each heating plate 26 is located between two water-cooling rings 31, and then the first motor 24 rotates in the opposite direction, so that the pawl 122 is in meshing connection with the ratchet 36, and the first motor 24, the bracket 21 and the slide bar 22 rotate half a circle, thereby making the heating plates 26 and The water-cooling ring 31 rotates, wherein the first counterweight block 35 adjusts its position by axial rotation so as to always keep it in a vertical state, and the two sealing blocks 34 slide downward by their own weight, so that the sealing blocks 34 and the sealing plates 33 form an annular seal to isolate a plurality of heating chambers, further realizing segmented heating of the surface of the hot-melt adhesive material, and the transmission rod 25 rotates in the positive direction again to adjust the arrangement of a plurality of heating plates 26, and finally, through the external control system, the heating plates 26 are made to work, respectively heating each heating chamber, and the water-cooling ring 31 cools the surface of the heating roller 12, the pressure roller 11 and the heating roller 12 rotate, and the hot-melt material is contacted and compounded with the coating, so that during the heating process, the shape of the hot-melt material can be guaranteed, and the hot-melt material can be prevented from being fully heated, resulting in the hot-melt material being soft and deformed, and causing uneven hot-melt compounding; Centralized hot-melt material heating: The transmission rod 25 is driven to rotate by the first motor 24, and the pawl 122 and the ratchet 36 are in non-meshing sliding connection, so that the heating plate 26 slides in the guide groove 251 through the guide rod 261 and gathers toward the middle, and a plurality of water-cooling rings 31 are moved to both sides and squeezed against each other on one of the slide rods 22 through the pneumatic slider 311. Water droplets are generated on the surface of the plurality of water-cooling rings 31 due to the hot and cold contact, and two adjacent annular sponges 37 squeeze against each other to squeeze out the water, which solves the humid environment of the heating chamber. When the heating roller 12 rotates continuously, the water flows out of the heating roller 12 through the spiral groove 123. In the centralized heating, the temperature can be quickly increased, the temperature is uniform, and the heating area is integrated, which improves the bonding ability; Composite coating cooling: After hot melt composite coating, the material is transported through the pressure roller 11, where the coating passes through the composite coating cooling zone 8 to cool the coating. Heat is transferred through the pressure roller 11, and the cooling water inside it reduces the surface temperature of the pressure roller 11. The water-blocking plate 41 can scrape the cooling liquid on the inner wall of the pressure roller 11, and the pressure roller 11 rotates continuously, causing the cooling liquid inside it to flow continuously, thereby achieving efficient cooling of the pressure roller 11.
