[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] In order to solve the technical problem of poor compaction effect caused by poor temperature controllability, the utility model provides a PVC board laminating device, which can effectively improve the compaction effect.

[0026] It should be noted that the PVC board laminating device described in the present invention is used for but not limited to PVC board laminating, etc. For the convenience of explanation, in the present invention, only a PVC board laminating device applied to PVC board laminating equipment is used as an example for explanation. The principle of applying a PVC board laminating device to other types of equipment is essentially the same as the principle applied to the PVC board laminating equipment, so they will not be repeated here.

[0027] See also Figure 1 - Figure 5 , Figure 1 This is a structural schematic diagram of a PVC board laminating device in one embodiment of the present invention, a PVC board laminating device, including a machine 100, a transmission mechanism 200, a laminating mechanism 300 and a pressing mechanism 400; the transmission mechanism 200 is arranged on the machine 100; the laminating mechanism 300 is covered on the top side of the machine 100; the pressing mechanism 400 includes at least two pressing rollers 410, a trimming pressure plate 420 and a heating box 430, the bottom end of the pressing roller 410 close to the transmission mechanism 200 is located below the bottom end of the other pressing roller 410, the bottom end of the trimming pressure plate 420 and the bottom end of the other pressing roller 410 are located on the same horizontal plane, and the heating box 430 is connected to the pressing roller 410.

[0028] In this embodiment, a compacting structure is constructed by providing two pressing rollers 410, a trimming plate 420, and a heating box 430. Furthermore, the bottom end of the pressing roller 410 on the side closest to the transmission mechanism 200 is located below the bottom end of the other pressing roller 410. This allows the two pressing rollers 410 to form a multi-stage compaction structure, effectively ensuring that the film passes through the two pressing rollers 410 in sequence and receives varying degrees of compaction. Furthermore, the trimming plate 420 instantly and comprehensively compacts and trims the film, effectively improving the compaction effect. During this process, the heating box 430 only needs to operate at a low temperature to ensure that the temperature of the pressing roller 410 is higher than the ambient temperature.

[0029] In one embodiment, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 , the diameter of the pressing roller 410 on the side close to the transmission mechanism 200 is larger than the diameter of the other pressing roller 410.

[0030] In this embodiment, the diameter of the pressure roller 410 on the side close to the transmission mechanism 200 is larger than the diameter of the other pressure roller 410. In this way, the coated PVC board can be pressed by the pressure roller 410 and then pressed more firmly by the other pressure roller 410, thereby improving the pressing effect.

[0031] In one embodiment, see Figure 1 The heating boxes 430 are arranged in pairs, and the heating boxes 430 correspond to the pressure rollers 410 one by one.

[0032] In this embodiment, the heating box 430 corresponds to the pressure roller 410 one by one, so that the temperature of the two heating boxes 430 can be independently adjusted according to actual needs, thereby making the temperature inside the two pressure rollers 410 different, which is convenient for adjusting the pressing effect of the pressure roller 410 after heating.

[0033] In one embodiment, see Figure 3 , the distance between the two pressing rollers 410 is greater than the distance between the other pressing roller 410 and the edge trimming pressing plate 420 .

[0034] In this embodiment, the distance between the two pressing rollers 410 is greater than the distance between the other pressing roller 410 and the edge trimming plate 420. This ensures that the coating has enough time to stretch while being pressed by the pressing rollers, and exposes any bubbling that may occur. It is then compacted and pressed under the action of the other pressing roller 410 and the edge trimming plate 420, thereby ultimately improving the compaction effect.

[0035] In one embodiment, see Figure 1 、 Figure 3 、 Figure 4The bottom end of the edge trimming pressing plate 420 is provided with a horizontal edge trimming surface 421 , and a chamfer 422 is provided on the side of the horizontal edge trimming surface 421 facing away from the pressing roller 410 .

[0036] In this embodiment, the chamfer 422 is provided to facilitate smooth transmission of the PVC board.

[0037] In one embodiment, see Figure 3 、 Figure 4 , the width of the horizontal edge surface 421 is at least 2 cm.

[0038] In this embodiment, the width of the horizontal trimming surface 421 should be set based on the effective pressing area of ​​the coating.

[0039] In one embodiment, see Figure 1 、 Figure 2 A groove 110 is provided at the top of the machine 100 , and the transmission mechanism 200 includes a transmission belt 210 and a motor 220 . The transmission belt 210 is installed in the groove 110 , and the motor 220 is installed on one side of the outer wall of the machine 100 and is transmission-connected to the transmission belt 210 .

[0040] In one embodiment, see Figure 1 The heating box 430 includes a box body 431 and a resistance wire 432 , and the resistance wire 432 is detachably connected to the box body 431 .

[0041] In this embodiment, the heat generated by the resistance wire 432 is dissipated through the housing 431 into the corresponding pressure roller 410, thereby ensuring that the pressure roller 410 can achieve relatively stable high-temperature compression while heated. It should be noted that the heat dissipation of the resistance wire 432 is sufficient to ensure that the outer wall temperature of the pressure roller 410 is higher than the external environment, thereby avoiding problems such as yellowing of the coating caused by excessive temperature.

[0042] In one embodiment, see Figure 1 The heating box 430 also includes a temperature sensor 433 , one end of which extends into the box body 431 .

[0043] In this embodiment, one end of the temperature sensor 433 extends into the box 431 to sense temperature changes.

[0044] In one embodiment, see Figure 1 An alarm 434 is provided at the top of the temperature sensor 433 .

[0045] In this embodiment, the alarm 434 issues appropriate warnings according to the temperature variation range, thereby facilitating the operator to adjust the temperature of the heating box 430 or perform intermittent shutdown.

[0046] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0047] First, the PVC board is placed on one side of the top of the machine 100 and moved under the transmission of the conveyor belt 210; then, the laminating mechanism 300 coats the PVC board; then, when the PVC board continues to move until it abuts against the first pressing roller 410, the pressing roller 410 presses the coating; then the PVC board continues to move and abuts against another pressing rod 410 and is pressed by the pressing roller 410; since the distance between the two pressing rollers 410 and the PVC board is gradually narrowed, the pressure applied to the coating of the PVC board is gradually increased, which effectively realizes multi-level compression and avoids blistering and non-compaction of the coating; then, the PVC board continues to move until it abuts against the edge pressing plate 420, and the horizontal edge finishing surface 421 of the edge finishing plate 420 compacts and trims the coating in all directions, effectively avoiding residual small bubbles and improving the overall compression effect. The above structure can effectively ensure and improve the compaction effect through heating and multi-stage compaction structure under a small range of temperature increase, and also avoids the technical problem of poor compaction effect caused by poor temperature controllability.

[0048] The above specific embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
