Description

Technical Field

[0001] This application relates to the technical field of PVC processing, and more specifically, to a heat-applying device for a PVC laminating and embossing machine. Background Technology

[0002] A PVC laminating and embossing machine is a specialized piece of machinery used for embossing and laminating PVC (polyvinyl chloride) materials. It is widely used in the production of PVC flooring, wallpaper, artificial leather, advertising film, and other products, giving PVC materials unique textures and functionalities through embossing and lamination processes.

[0003] In related technologies, PVC laminating and embossing machines typically include an unwinding device, a preheating device, an embossing device, a heat-bonding device, a cooling device, and a rewinding device. These devices are sequentially arranged on a frame. The unwinding device places and unfolds the PVC roll, ensuring the material enters the processing area smoothly. The preheating device preheats the PVC material, softening it to facilitate subsequent embossing and lamination. The embossing device presses the desired texture onto the PVC surface. The heat-bonding device laminates the PVC material to the substrate, ensuring high-quality lamination and maintaining a stable texture effect after embossing. The cooling device cools the processed material... The material is rapidly cooled to prevent deformation and maintain texture stability; the processed PVC material is wound into rolls by a winding device for easy storage and transportation; the embossing device includes an embossing roller and a pressure roller, and the heat-applying device is usually close to and fixed to one side of the embossing roller. In actual production, different textures usually require different embossing rollers, resulting in inconsistent sizes of the assembled embossing rollers. Therefore, it is difficult for the fixed heat-applying device to adapt to embossing rollers of different sizes to maintain a suitable distance between the embossing roller and the heat-applying device. In fact, larger embossing rollers are prone to interference with the heat-applying device during operation, causing safety accidents. Utility Model Content

[0004] In order to solve the problem that the fixed assembly of the heat-applying device and the frame in the related technology is difficult to adapt to embossing rollers of different sizes, this application provides a heat-applying device for a PVC laminating and embossing machine.

[0005] A heat-applying device for a PVC laminating and embossing machine includes a base frame. Slide rails are provided on opposite sides of the top surface of the base frame. Slider blocks are slidably mounted on each slide rail. A mounting plate is fixed to each slider. A heat-applying mechanism for PVC is fixed to the top surfaces of both mounting plates. A rack is connected to the bottom of each mounting plate, parallel to the slide rails. A rotating shaft is rotatably mounted on the base frame. The rotating shaft is horizontally positioned and its length direction is perpendicular to the slide rails, and it is located below the racks. Gears are connected to both ends of the rotating shaft. One gear meshes with one rack, and the other gear meshes with another rack. A worm gear reducer is also fixed on the base frame. The output end of the worm gear reducer is connected to the rotating shaft. A driving component is connected to the worm gear reducer to drive its rotation, thereby driving the worm gear reducer to rotate the rotating shaft.

[0006] Preferably, the driving component is a servo motor, the drive shaft of the servo motor is connected to the input end of the worm gear reducer, and the outer housing of the servo motor is fixedly connected to the outer housing of the worm gear reducer.

[0007] Preferably, the driving component is a rotary handle, which is connected to the input end of the worm gear reducer.

[0008] Preferably, the base frame is provided with a bearing seat, the bearing seat is provided with a ball bearing, and the rotating shaft passes through the inner ring of the ball bearing and is connected and fixed thereto.

[0009] Preferably, the mounting plate and the slider are locked together by bolts.

[0010] The beneficial technical effects of this application are as follows: By connecting the base frame to the machine frame, the worm gear reducer is driven by the drive component to rotate the shaft. The rotation of the shaft drives the gear to rotate, which in turn drives the rack to move. The rack's movement then moves the mounting plate and the heat-applying mechanism fixed to the mounting plate, thus adjusting the position of the heat-applying mechanism. Furthermore, the self-locking property of the worm gear reducer locks the mounting plate in the adjusted position, ensuring stable operation of the heat-applying mechanism. The position adjustment of the heat-applying mechanism allows it to be adjusted to a position compatible with the embossing roller of different sizes, meeting process requirements. This reduces interference between the embossing roller and the heat-applying mechanism, lowers the incidence of safety accidents, and makes the PVC laminating and embossing machine safer, more reliable, and more flexible overall.

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] Example 1

[0015] Reference Figure 1 A heat-applying device for a PVC laminating and embossing machine includes a base frame 1. Slide rails 11 are provided on opposite sides of the top surface of the base frame 1. Slider blocks 12 are slidably mounted on each slide rail 11. Each slider 12 is fixed to a mounting plate 2 by bolts. A heat-applying mechanism 3 is fixed to the top surface of both mounting plates 2. The heat-applying mechanism 3 is used to heat-apply PVC, bonding the PVC material to the substrate. This ensures high-quality lamination and maintains a stable texture effect after embossing, making it less prone to texture loss and facilitating greater inventory for manufacturers. Each mounting plate 2 has a rack 21 connected to its bottom, parallel to the slide rails 11. A bearing seat 13 is provided on the base frame 1, containing a ball bearing 14. A rotating shaft 15 is threaded through the ball bearing 14. The inner ring of the ball bearing 14 is fixed to the shaft 15. The shaft 15 is rotatably connected to the base frame 1 through the support of the ball bearing 14. The shaft 15 is arranged laterally and its length direction is perpendicular to the slide rail 11. The shaft 15 is located below the rack 21, and both ends of the shaft 15 are connected to gears 16. One gear 16 meshes with one rack 21, and the other gear 16 meshes with another rack 21. A worm gear reducer 4 is also fixed on the base frame 1. The output end of the worm gear reducer 4 is connected to one end of the shaft 15. A drive component 5 is connected to the worm gear reducer 4. The drive component 5 is a servo motor, and the drive shaft of the servo motor is connected to the input end of the worm gear reducer 4. The outer housing of the servo motor is connected to the outer housing of the worm gear reducer 4 to fix the servo motor.

[0016] In the above structure, the base frame 1 is connected to the frame of the PVC laminating and embossing machine. A servo motor drives the worm gear reducer 4, causing the rotating shaft 15 to rotate. The rotation of the rotating shaft 15 drives the gear 16, which in turn drives the rack 21 to move. The movement of the rack 21 then moves the mounting plate 2 and the heat-applying mechanism 3 fixed to the mounting plate 2, allowing the heat-applying mechanism 3 to adjust its position. The self-locking property of the worm gear reducer 4 locks the mounting plate 2 in the adjusted position, ensuring stable operation of the heat-applying mechanism 3. The position adjustment of the heat-applying mechanism 3 allows it to be adjusted to a position compatible with different sized embossing rollers, reducing interference between the embossing roller and the heat-applying mechanism 3, lowering the incidence of accidents, and making the PVC laminating and embossing machine safer, more reliable, and more flexible overall. Furthermore, the use of a servo motor drive results in a high degree of automation, saving labor costs.

[0017] Reference Figure 1 Furthermore, the heat-applying mechanism 3 includes steel rollers 31 and a rotation drive assembly 32. The number of steel rollers is three, and the three steel rollers 31 are arranged at intervals along the length of the slide rail 11 on the mounting plate 2. Each mounting plate 2 is provided with a support seat 22 matching the number of steel rollers. The end of each steel roller 31 is connected to a support seat 22 to obtain rotational support from the support seat 22. The three steel rollers 31 are arranged in parallel, and the interior of each steel roller is hollow, with a heating element installed inside. The heating element generates heat and conducts it to the surface of the steel roller 31. The rotation drive assembly 32 is fixed on a mounting plate 2. The rotation drive assembly 32 drives the three steel rollers 31 to rotate synchronously. The rotation of the steel rollers contacts the PVC material to heat and pressurize the PVC material, thereby achieving the bonding of the PVC material with the substrate and ensuring that the PVC material can be bonded with high quality and maintain a stable texture effect after embossing. The rotation drive assembly 32 is a combination of a servo motor and a transmission structure. The transmission structure can preferably be a gear meshing structure or a belt and pulley transmission structure. The transmission structure that works with the servo motor to drive the three steel rollers 31 to rotate synchronously is existing technology and will not be described in detail in this embodiment.

[0018] Example 2

[0019] The difference between Example 2 and Example 1 lies in the different driving component 5. In this example, the driving component 5 used to drive the worm gear reducer 4 is a rotary handle (not shown in the figure). The rotary handle is connected to the input end of the worm gear reducer 4. The electric worm gear reducer 4 is operated by manually rotating the rotary handle, which is convenient for saving energy.

[0020] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
