Technical Field

[0001] This utility model relates to a surface finishing processing equipment, and more particularly to an arc rolling surface bonding equipment. Background Technology

[0002] In the decoration industry, this involves some woodwork or other products with rounded corners. The common practice in the market is to use a one-piece molding process to avoid deformation and cracking after long-term use. However, this method has high investment costs, low yield, long production cycles, high expenses, and high dependence on skilled workers, making it difficult to meet current usage needs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a circular arc rolling and bonding device.

[0019] like Figures 1-3 As shown, an arc-shaped rolling and bonding machine includes a frame 1, an upper roller 2, a lower roller 3, and a heating device. In this embodiment, the heating device is a hot oil supply device, a mature technology product, and will not be elaborated or limited further here. After the rough arc is coated with adhesive, two surface layers are added. The surface layers are bonded by the curved heating of the machine to achieve the designed effect. There are two rollers, the lower roller's cross-section is flush with the table 4, and one side of the table 4 extends out for feeding. The feeding point can hold the upper and lower surface layers and the middle arc-shaped rough material, and the three are pre-treated and aligned. The rolling and pressing has a certain pressure, and both rollers can have heating devices, using heated oil. In this embodiment, a single upper roller 2 is used as an example to illustrate some of the implementation difficulties.

[0020] The frame 1 has a horizontally arranged platform 4, within which a chamber 5 and an opening extending to the platform 4 are provided. The lower roller 3 is rotatably mounted in the chamber 5, and the upper roller 2 is fixedly mounted on the frame 1, positioned above the lower roller 3. The horizontal cross-sections of the upper roller 2 and the lower roller 3 are spaced apart by a pressure surface distance, which is less than the thickness of the raw material to be processed. The heating device is connected to either the upper roller 2 or the lower roller 3, and a heating arc surface is formed on the surface of either the upper roller 2 or the lower roller 3. The top cross-section of the lower roller 3 is flush with the platform 4. The pressure surface distance between the upper roller 2 and the lower roller 3 is less than the thickness of the stacked raw material, thus creating a relative pressing force. The relatively horizontal height arrangement of the lower roller 3 facilitates the translation of the material for processing without the need for lifting and angle adjustment, simplifying the processing structure.

[0021] The frame 1 is also equipped with a limiting frame 6 and a lifting mechanism. The upper roller shaft 2 is limited and assembled at the limiting frame 6 to form a vertical movement path. The limiting frame 6 can be in the form of a slide rail, which is not strictly limited here. The upper roller shaft 2 is linked with the lifting mechanism. The lifting mechanism includes a wheel 7, a front drive gear 8, a lead screw 9, and a rear drive gear 10 that are sequentially meshed and linked. The axes of the wheel 7 and the lead screw 9 are parallel. The rear drive gear 10 is fixedly assembled with the end of the upper roller shaft 2, and the front drive gear 8 is fixedly assembled with the end of the lead screw 9. The front drive gear 8 can be a worm gear to change the transmission direction, which meets the design requirements. By operating the wheel 7, the transmission components are driven to move sequentially, causing the upper roller shaft 2 to move up and down slightly to adjust the pressure surface spacing. It should be noted that the limiting and movable assembly of the wheel 7, lead screw 9, etc., is on the table surface 4 of the frame 1.

[0022] The upper roller 2 has an internally hollowed-out chamber 11 in its middle section, which is connected to the heating device. The heating device introduces a high-temperature medium into the chamber 11, facilitating continuous heating to reach the design temperature. It can also be equipped with sensors such as thermometers. A pressure relief valve and heat dissipation holes are also included to prevent localized overheating. The chamber 11 also contains a coil 12 connected to the heating device. In this embodiment, indirect heating is achieved using the coil 12, which can utilize air or water for indirect heat conduction and insulation. The frame 1 also has hollowed-out movable slots (not shown) on both sides of the hopper opening to facilitate material reversal for heating. When both the upper roller 2 and lower roller 3 adopt a structure with the heating device introduced, only one processing step is required. This embodiment primarily considers that the rotational state of the lower roller 3 is not conducive to the sealing connection of the hot oil medium pipeline; however, using special connectors or other media can also meet the usage requirements.

[0023] Example 2: Different from Example 1, such as Figure 4As shown, the upper roller shaft 2 and the lower roller shaft 3 are connected by a chain drive, and both the upper roller shaft 2 and the lower roller shaft 3 are equipped with a rotary joint 4 for connecting the heating device. The distance between the upper roller shaft 2 and the lower roller shaft 3 is relatively constant, reducing design complexity, while the rotary joint 4 facilitates management and connection. It should be noted that the rotary joint 4 is a pipeline connection device, and the connected pipelines can rotate relative to each other, which can be used to transport various media such as gas, liquid, and oil in a compact design. A flange connection is used, which can be effectively integrated into the customer's equipment. Rotary joints come in various styles, which will not be elaborated or limited here, but are suitable for the case where both the upper roller shaft 2 and the lower roller shaft 3 are heated in this embodiment. An auxiliary frame 5 is also provided at the upper roller shaft 2 or the lower roller shaft 3. The auxiliary frame is equipped with paired and stably fitted rollers, which is beneficial for smooth rotation and uniform heating.

Therefore, they should not be construed as limitations on this utility model.
