[0020] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0021] This application provides a vacuum composite roller device, which is installed on a forming equipment to continuously evacuate a sheet material that passes around the vacuum composite roller device, thereby forming multiple protrusions on the surface of the sheet material and achieving stable forming of a composite plate with multiple protrusions on the surface.

[0022] like Figure 1 As shown, the vacuum composite roller device includes a composite roller 10 and a vacuum pumping mechanism 20. The composite roller 10 extends in the left-right direction and has a first end 101 and a second end 102 that are far apart from each other. The vacuum pumping mechanism 20 is installed at the first end 101 and continuously evacuates the composite roller 10.

[0023] like Figure 2-8 As shown, the interior of the composite roller 10 has a plurality of transverse air grooves 11 arranged at intervals along the circumference of the composite roller 10. Each transverse air groove 11 extends in the left-right direction. The plurality of transverse air grooves 11 form a plurality of air extraction holes 12 at the first end 101 of the composite roller 10. The plurality of air extraction holes 12 are arranged in an array along the circumference of the first end 101 of the composite roller 10.

[0024] The surface of the composite roller 10 is formed with a plurality of suction groups 21 distributed circumferentially along the composite roller 10. The plurality of suction groups 21 correspond one-to-one with a plurality of transverse air grooves 11. Each suction group 21 includes a plurality of suction circular grooves 210 connected to the corresponding transverse air groove 11.

[0025] During the rotation of the composite roller 10, the vacuum mechanism 20 sequentially draws air from multiple air extraction holes 12, applies a negative pressure to the transverse air grooves 11 corresponding to the air extraction holes 12, and achieves vacuuming of multiple air extraction grooves 210 in the connected suction group 21. Under the vacuuming action of multiple air extraction grooves 210, multiple protrusions are formed on the surface of the sheet that passes around the composite roller 10.

[0026] The composite roller 10 includes an inner roller liner 1 and a roller body 2 coaxially sleeved on the outer surface of the inner roller liner 1. Multiple transverse air grooves 11 are formed on the outer surface of the inner roller liner 1. The inner surface of the roller body 2 and the multiple transverse air grooves 11 define the aforementioned multiple air extraction holes 12. Multiple air extraction circular grooves 210 are formed on the outer surface of the roller body 2. Each air extraction circular groove 210 has at least one air groove hole 211 at its bottom that communicates with the corresponding transverse air groove 11. The axis of each air groove hole 211 is perpendicular to the axis of the roller body 2.

[0027] like Figure 1 , 3 As shown in Figures 4 and 8, the vacuuming mechanism 20 includes a fixed plate 3, a suction plate 4, and at least one spring 5 pressed between the fixed plate 3 and the suction plate 4. The fixed plate 3 is mounted on the molding equipment by a plurality of mechanical fasteners and fixes the suction plate 4 to the outside of the first end 101, so that the vacuuming mechanism 20 can continuously vacuum the composite roller 10.

[0028] The suction plate 4 has suction through holes 41 extending in the left-right direction. The end of the suction through hole 41 away from the composite roller 10 is connected to the external vacuum system 7. The suction through hole 41 is configured to connect sequentially to a plurality of suction holes 12 when the composite roller 10 rotates. The vacuum system 7 includes a vacuum pump 71 and a suction pipe 72 connecting the vacuum pump 71 and the suction through hole 41. The vacuum pump 71 applies a suction negative pressure in the suction through hole 41 through the suction pipe 72 and evacuates the plurality of suction groups 21 on the composite roller 10 through the suction through hole 41.

[0029] At least one spring 5 is located between the fixed plate 3 and the suction plate 4. Through its own spring preload, the suction plate 4 is pressed against the first end 101 of the composite roller 10 to prevent air leakage between the suction plate 4 and the composite roller 10, thus ensuring the suction efficiency of the vacuum mechanism 20 on the composite roller 10.

[0030] The vacuum mechanism 20 also includes a slide plate 6 connected between the fixed plate 3 and at least one spring 5. The slide plate 6 is movably mounted on the fixed plate 3. The slide plate 6 can drive the suction plate 4 to move circumferentially along the composite roller 10, so that the suction through hole 41 changes the angle in the circumferential direction of the composite roller 10, thereby changing the suction angle on the composite roller 10 to suit the production of different composite sheets.

[0031] The vacuum mechanism of this application has a simple structure, which effectively reduces the production cost of the vacuum composite roller device. The suction plate is pressed against the composite roller by a spring, and the suction angle of the composite roller can be quickly adjusted by the connection between the sliding plate and the fixed plate, which effectively improves production efficiency.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
