Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of composite material preparation, and more specifically, to a roller pressure control system for wood-plastic composite materials. Background Art
[0002] Conventional first-generation wood-plastic boards in wood-plastic composites can only be presented in darker color systems due to their physical properties, apparent states, and raw material costs. The color is single. With the market demand, second-generation co-extruded wood-plastic boards with multiple color systems and multiple patterns have been developed. Since the apparent patterns of the second-generation co-extruded wood-plastic boards need to be pressed by rollers, the pressure between the rollers and the boards cannot be detected, and the pressure between the rollers and the boards can only be adjusted by the naked eye or experience. This results in the inability to control the depth of the embossed patterns, the size of the boards, and the flatness, seriously affecting the production stability and product qualification rate, and restricting the development of the wood-plastic composite material industry to a certain extent. Therefore, there is an urgent need for a controllable and easy-to-operate roller pressure control system for wood-plastic composite materials. Summary of the Invention
[0003] The purpose of the present invention is to provide a roller pressure control system for wood-plastic composite materials to solve the problems existing in the above-mentioned prior art, and to achieve the control of the depth of the embossed patterns, the size, and the flatness of the wood-plastic composite materials, and improve the production stability and product qualification rate.
[0004] To achieve the above purpose, the present invention provides the following solutions:
[0005] The present invention provides a roller pressure control system for wood-plastic composite materials, including two pressure control modules. The two pressure control modules are respectively installed at both ends of the embossing roller. The pressure control module includes a pressure monitoring element, an outer frame, two pressure applying elements, and two end mounting elements. The two pressure applying elements are symmetrically arranged and respectively installed at the upper and lower ends of the outer frame. The two end mounting elements are both movably installed in the outer frame. Each of the two pressure applying elements is correspondingly connected to one of the end mounting elements. In the same outer frame, the two end mounting elements are arranged vertically and are respectively used to connect the ends of different embossing rollers. The pressure monitoring element is installed between the pressure applying element located above and the outer frame.
[0006] Preferably, the end mounting element includes a support frame and a bearing. The support frame is movably installed in the outer frame. The bearing is installed in the support frame, and the bearing is rotatably connected to the end of the rotating shaft of the embossing roller.
[0007] Preferably, the pressure applying element includes a threaded pressure rod and two adjusting nuts. The threaded pressure rod is threadedly connected to the upper end of the outer frame. Both of the adjusting nuts are threadedly connected to the outer periphery of the threaded pressure rod. The lower end of the threaded pressure rod passes through the connecting plate body of the support frame and extends into the support frame. The two adjusting nuts are respectively located at the upper and lower ends of the connecting plate body.
[0008] Preferably, a handle is provided at one end of the threaded pressure rod away from the end mounting element.
[0009] Preferably, the pressure monitoring element includes a pressure display, a pressure sensor and a mounting plate. The pressure sensor is movably mounted on the outer periphery of the upper threaded pressure rod through the mounting plate and is connected to the upper end of the outer frame. The pressure display is electrically connected to the pressure sensor.
[0010] Preferably, a receiving frame is further installed at the lower end of the outer frame. The lower end of the pressure applying element located below is located within the receiving frame.
[0011] The present invention has achieved the following technical effects compared with the prior art:
[0012] The wood-plastic composite roller pressure control system provided by the present invention has two pressure control modules respectively installed at both ends of the embossing roller, and thus can separately control the pressure values on both sides of the embossing roller. The pressure control module includes a pressure monitoring element, an outer frame, two pressure applying elements and two end mounting elements. The two pressure applying elements are symmetrically arranged and respectively installed at the upper and lower ends of the outer frame, which is convenient for adjusting the distance between the two embossing rollers and the pressure acting on the plate through the pressure applying elements and the end mounting elements. The two end mounting elements are both movably installed within the outer frame. Each of the two pressure applying elements is correspondingly connected to an end mounting element. Within the same outer frame, the two end mounting elements are arranged vertically and are respectively used to connect the ends of different embossing rollers. The pressure monitoring element is installed between the upper pressure applying element and the outer frame. Through the setting of the pressure monitoring element, the magnitude of the contact pressure between the embossing roller and the plate can be displayed in real time, realizing pressure visualization and achieving precise control. At the same time, by adjusting the pressure applying elements on both sides of the embossing roller to control the pressure between the embossing roller and the plate, the problems that the depth, size and flatness of the embossed pattern of the wood-plastic composite material are difficult to control are solved.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0017] The purpose of the present invention is to provide a roller pressure control system for wood-plastic composite materials to solve the technical problems that it is difficult to control the depth of the embossed pattern, the size, and the flatness of the wood-plastic composite materials.
[0018] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] As Figure 1 shown, this embodiment provides a roller pressure control system for wood-plastic composite materials, including two pressure control modules. The two pressure control modules are respectively installed at both ends of the embossing roller 11, so as to separately control the pressure values on both sides of the embossing roller 11. The pressure control module includes a pressure monitoring element, an outer frame 5, two pressure applying elements, and two end mounting elements. The two pressure applying elements are symmetrically arranged and respectively installed at the upper and lower ends of the outer frame 5, which is convenient for adjusting the distance between the two embossing rollers 11 and the pressure acting on the plate 10 through the pressure applying elements and the end mounting elements. The two end mounting elements are both movably installed in the outer frame 5. Each of the two pressure applying elements is correspondingly connected to an end mounting element. In the same outer frame 5, the two end mounting elements are arranged vertically and are respectively used to connect the ends of different embossing rollers 11. The pressure monitoring element is installed between the upper pressure applying element and the outer frame 5. Through the setting of the pressure monitoring element, the magnitude of the contact pressure between the embossing roller 11 and the plate 10 can be displayed in real time, realizing pressure visualization and achieving precise control. At the same time, by adjusting the pressure applying elements on both sides of the embossing roller 11, the pressure between the embossing roller 11 and the plate 10 is controlled, solving the problems that it is difficult to control the depth of the embossed pattern, the size, and the flatness of the wood-plastic composite materials.
[0020] Specifically, the end mounting element includes a support frame 7 and a bearing 9. The support frame 7 is movably mounted within the outer frame 5, and the bearing 9 is mounted within the support frame 7. The bearing 9 is rotatably connected to the end of the rotating shaft 8 of the embossing roller 11. Through the arrangement of the bearing 9 and the support frame 7, while supporting the embossing roller 11, it can also avoid affecting the rotation of the embossing roller 11.
[0021] The pressure applying element includes a threaded pressure rod 1 and two adjusting nuts 6. The threaded pressure rod 1 is threadedly connected to the upper end of the outer frame 5, and both of the two adjusting nuts 6 are threadedly connected to the outer periphery of the threaded pressure rod 1. The lower end of the threaded pressure rod 1 passes through the connecting plate body of the support frame 7 and extends into the support frame 7. The two adjusting nuts 6 are respectively located at the upper and lower ends of the connecting plate body. Through the cooperation of the two adjusting nuts 6 and the threaded pressure rod 1, when the pressure needs to be adjusted, first loosen the two adjusting nuts 6, and then rotate the threaded pressure rod 1 to move the threaded pressure rod 1 upward or downward to adjust the magnitude of the applied pressure. At the same time, the pressure is monitored in real time through the pressure monitoring element. After the adjustment is in place, by tightening the adjusting nuts 6, the position of the threaded pressure rod 1 is fixed, and thus the pressure can be stably applied.
[0022] A handle is provided at one end of the threaded pressure rod 1 away from the end mounting element, which facilitates adjustment and operation.
[0023] The pressure monitoring element includes a pressure display 2, a pressure sensor 3, and a mounting plate 4. The pressure sensor 3 is movably mounted on the outer periphery of the upper threaded pressure rod 1 through the mounting plate 4 and is connected to the upper end of the outer frame 5. The pressure display 2 is electrically connected to the pressure sensor 3. By detecting the pressure in real time through the pressure sensor 3 and then displaying the detected pressure value through the pressure display 2, the visualization of the contact force between the embossing roller 11 and the sheet 10 can be achieved.
[0024] A receiving frame is further mounted at the lower end of the outer frame 5, and the lower end of the pressure applying element located below is located within the receiving frame, which facilitates the operation of the handle of the lower threaded pressure rod 1.
[0025] In this specification, specific examples are used to elaborate on the principles and implementation manners of the present invention. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
