Description

Technical Field

[0001] This utility model relates to the technical field of three-layer embossing and bonding devices, and in particular to a three-layer embossing and bonding device for PVC plastic tablecloths. Background Technology

[0002] VC plastic tablecloths are functional desktop covering materials made primarily of polyvinyl chloride (PVC) through processes such as calendering and lamination. They are typically available in sheet or flexible roll form and are mainly used to protect desktops, improve ease of use, or decorate the desktop environment.

[0003] In related technologies, a prominent technical challenge exists in the embossing and lamination process of PVC plastic tablecloths widely used in the market: due to material properties and process limitations, relative displacement and misalignment easily occur between layers during the lamination of multiple layers. This interlayer misalignment leads to significant deviations and deformations in the embossed pattern, severely affecting not only the overall aesthetics and consistency of the embossed lamination but also reducing the product qualification rate. More seriously, this process defect significantly increases the rework rate and scrap rate during production, thereby drastically reducing the overall processing efficiency of PVC plastic tablecloths and increasing production costs.

[0004] To address this issue, a three-layer embossing and bonding device for PVC plastic tablecloths is proposed. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a three-layer embossing and bonding device for PVC plastic tablecloths, which aims to improve the existing three-layer embossing and bonding device: Currently, when PVC plastic tablecloths are embossed and bonded, the multiple layers are prone to misalignment, resulting in disordered embossing, affecting the embossing and bonding effect, and reducing the processing efficiency of PVC plastic tablecloths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a three-layer embossing and bonding device for PVC plastic tablecloths, comprising: a three-layer embossing and bonding device, wherein a roll unwinding roller is fixedly installed on the left side of the top of the three-layer embossing and bonding device, an embossing roller is provided inside the three-layer embossing and bonding device, and two fixing plates are fixedly connected to the left side of the three-layer embossing and bonding device. A fixing frame is provided inside the fixing plate, and an adjustment structure is provided inside the fixing frame. A transmission component is provided on the top of the fixing plate. The adjustment structure is used to press and transmit three-layer PVC plastic tablecloths of different thicknesses, and the transmission component is used to drive the adjustment structure.

[0007] As a further description of the above technical solution: the adjustment structure includes a bidirectional screw, which is rotatably connected inside the fixed plate. The top of the bidirectional screw extends through to the top of the fixed plate. A threaded sleeve is threaded onto the surface of the bidirectional screw, and the threaded sleeve is fixedly connected to the fixed frame. A pressure wheel is rotatably connected inside the fixed frame.

[0008] Through the above technical solution, the equipment can accurately press and fix three-layer PVC plastic tablecloths of different thicknesses by adjusting the structure. This adjustment mechanism not only ensures the tight fit between the multiple layers of materials and effectively prevents the occurrence of interlayer misalignment, but also has excellent fastening performance, fundamentally solving the problem of interlayer misalignment that easily occurs in the processing of PVC plastic tablecloths.

[0009] As a further description of the above technical solution: the transmission assembly includes a synchronous gear, which is fixedly connected to the top of the surface of the bidirectional screw. A synchronous belt is provided on the top of the fixed plate, and the synchronous belt meshes with the synchronous gear. Metal frames are fixedly connected to both sides of the top of the fixed plate. The metal frames are rotatably connected to the bidirectional screw. A servo motor is fixedly connected to the top of the metal frame, and the output end of the servo motor is fixedly connected to the top of the bidirectional screw.

[0010] Through the above technical solution, the transmission system is designed to achieve smooth control of the adjustment structure through precise mechanical transmission. This transmission method ensures the stability of the equipment during the lifting and adjusting process, and the operation is smooth and reliable, greatly improving the user's ease of operation.

[0011] As a further description of the above technical solution: it also includes a limiting component, the limiting component including a support plate, the support plate being fixedly connected to the top of a fixed plate, a slide rod being slidably connected inside the support plate, a limiting wheel being fixedly connected to the inner side of the slide rod, the limiting wheel being connected to a synchronous belt drive, a blocking disc being fixedly connected to the outer side of the slide rod, a tension spring being fixedly connected to the inner side of the blocking disc, and the inner side of the tension spring being fixedly connected to the surface of the support plate.

[0012] Through the above technical solution, by setting a limiting component, the transmission belt can be precisely limited and controlled. This design significantly improves transmission efficiency, effectively avoids the slippage that may occur in the synchronous gear during operation, and ensures the efficient and stable operation of the entire transmission system.

[0013] As a further description of the above technical solution: a limiting rod is fixedly connected to the outer side of the limiting wheel, and the limiting rod is slidably connected to the support plate.

[0014] Through the above technical solution and the setting of the limit rod, this structure ensures the stability of the limit wheel during operation and completely eliminates the possibility of the limit wheel tilting left or right. This not only improves the safety of equipment operation but also brings great convenience to users.

[0015] As a further description of the above technical solution: a metal rod is vertically fixedly connected to the inner side of the fixing plate, and a metal ring is fixedly connected to the outer side of the fixing frame, with the metal rod and the metal ring being slidably connected.

[0016] Through the above technical solution, the metal rods provide strong support for the fixed frame.

[0017] As a further description of the above technical solution: the internal longitudinal rotatable connection of the three-layer embossing bonding device is a pressing roller, which is located at the bottom of the unwinding roller.

[0018] Through the above technical solution, the setting of the pressure roller can apply uniform pressure to the plastic tablecloth, ensuring that the plastic tablecloth always maintains an ideal tension state. This design not only ensures the stability of the plastic tablecloth during transmission, but also provides great convenience for users' operation.

[0019] This utility model has the following beneficial effects: 1.

At the same time, it is easy to operate and effectively improves the quality and efficiency of embossing. Through the bidirectional screw combined with synchronous gear and synchronous belt transmission, the synchronous lifting and lowering adjustment of the two sets of pressing wheels can be realized, which can accurately adapt to three-layer tablecloths of different thicknesses, and apply uniform pressing force to the material through the linkage of the screw sleeve and the fixing frame, fundamentally solving the problem of easy misalignment between layers in traditional devices and ensuring bonding accuracy.

[0020] 2. In this utility model, the reliability of the equipment is improved through the optimization of the auxiliary structure.

The sliding cooperation between the metal rod and the metal ring provides stable support for the fixed frame and prevents shaking during operation. These detailed designs further ensure transmission efficiency and structural stability, and improve the overall operational safety of the equipment. Attached Figure Description

[0033] Reference Figure 1-2 The internal longitudinal rotatable pressure roller 12 of the three-layer embossing bonding device 1 is located at the bottom of the unwinding roller 2. The pressure roller 12 is designed to apply uniform pressure to the plastic tablecloth, ensuring that the plastic tablecloth always maintains an ideal tension. This design not only ensures the stability of the plastic tablecloth during transmission, but also provides great convenience for users.

[0034] Working Principle: When embossing a three-layer PVC plastic tablecloth, the operator first needs to place the rolled PVC plastic tablecloth smoothly onto the unwinding roller 2 of the equipment. Then, one end of the tablecloth is passed through the bottom gap of the pressing roller 12 assembly, ensuring it passes smoothly and without wrinkles through the guide channel of the fixed guide plate, and finally enters the working area of ​​the embossing roller 3 for texture pressing. During this process, the operator needs to precisely adjust the working distance between the two sets of pressing rollers 63 according to the actual thickness parameters of the three-layer PVC plastic tablecloth being processed to ensure the best pressing effect. Once the preparation is complete, the operator starts the servo drive motor 74 system. The motor drives the bidirectional screw 61 to rotate precisely through the coupling. The rotation of the bidirectional screw 61 synchronously drives the synchronous gear 71 that meshes with it, thereby driving the annular synchronous belt 72 to rotate cyclically. This linkage design ensures that the two bidirectional screws 61 can maintain completely synchronized rotation. The synchronized rotation of the two bidirectional screws 61 drives the threaded sleeve assemblies on them to move horizontally. These threaded sleeves, in turn, drive the fixed bracket to move towards the center position through the connecting parts. This allows the pressure roller 63 mounted on the bracket to apply uniform pressure to the PVC plastic tablecloth, ensuring that the material maintains a stable transmission state during processing. In addition, the equipment is equipped with a tensioning system of tension spring 85 throughout the entire working process. Through the continuous tension applied by the tension spring 85, the slide rod 82 drives the limit wheel 83 to always maintain a moderate pressure on the synchronous belt 72. This design effectively ensures that the synchronous belt 72 is always in the optimal tension state, completely avoiding the tooth slippage phenomenon that may occur due to the slack of the synchronous belt 72, thereby ensuring the high stability and reliability of material transmission throughout the embossing process.
