Description

Technical Field

[0001] This utility model relates to the field of decorative paper production technology, and in particular to an unwinding device for decorative paper production. Background Technology

[0002] Decorative paper is a special industrial paper made primarily from wood pulp and titanium dioxide. It is produced through processes such as printing and melamine resin impregnation and is used for the surface finishing of artificial boards. It has the characteristics of being sun-resistant, wear-resistant, and aesthetically pleasing. According to its use, it is divided into printed decorative paper and impregnated film paper.

[0003] Decorative paper requires a smooth surface, good absorbency and adaptability. For paper with a base color, the color tone should be uniform, and for paper with color, the color should be bright. When the wound decorative paper is processed, the unwinding machine needs to unwind the wound film again for use in the next process. Conventional unwinding devices require aligning both ends of the roll with the limit end, clamping the limit from both ends, and then unwinding. This alignment process is inconvenient and makes it difficult to quickly place the finished roll and adjust it to an unwindable state, which is also inconvenient for operators. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an unwinding device for decorative paper production, thereby solving the problems mentioned in the background section.

[0005] A winding device for decorative paper production includes a base and a placement mechanism mounted on the base. The placement mechanism includes an adjustment component and a placement component mounted opposite to the adjustment component. The placement component includes a bracket, electric cylinders, lifting seats, two rollers, a rotating part, and a support plate. Two electric cylinders are mounted opposite to each other on the bracket. There are also two lifting seats, which are respectively fixedly mounted at the output end of the electric cylinders and slide relative to each other along the support plate fixed on the bracket. Two rotating parts are mounted on the lifting seats and are fitted together with the two rollers that are rotatably mounted on the lifting seats. The adjustment assembly includes a motor, a bidirectional lead screw, a guide rail, and a slide block. The bidirectional lead screw is fixedly installed at the output end of the motor. The guide rail is positioned on both sides of the bidirectional lead screw. The slide block slides along the guide rail and is fixed to the bottom of the bracket.

[0006] By adopting the above technical solution, it is convenient to place the roll with decorative paper on the device and quickly place and adjust it.

[0007] Rollers are also rotatably mounted on both sides of the arc-shaped groove of the bracket.

[0008] By adopting the above technical solution, the decorative paper can be released by rotating the roller.

[0009] The rotating part consists of a fixed column and a rotating ring. The rotating ring is rotatably mounted on the fixed column, and the fixed column is fixed to a right-angled surface of the right-angled plate of the lifting seat, which restricts the displacement of the roller of the decorative paper roll.

[0010] By adopting the above technical solution, the movement of the roll of decorative paper is restricted, allowing only rotation.

[0011] The second roller consists of two rollers that are rotatably mounted on the other right-angled surface of the right-angled plate of the lifting seat, and located on both sides of the bottom of the rotating ring of the corresponding rotating part.

[0012] By adopting the above technical solution, the stability of the rotating part is increased.

[0013] There is a gap between the two rotating parts in the same group, and the two groups of rotating parts are arranged in a one-to-one vertical correspondence. By adopting the above technical solution, it is possible to restrict both ends of the roll of finished decorative paper.

[0014] The beneficial effects of the unwinding device for decorative paper production of this utility model are: The two ends of the decorative paper roll are placed on two supports for support. Then, the two ends of the roll are moved to the arc groove. The two sets of placement components are driven by two corresponding electric cylinders, which push the lifting seat to move along the support plate. The lifting seat drives the rotating part so that the rotating ring of the rotating part can be embedded in the annular groove of the decorative paper roll, restricting the two ends of the decorative paper roll. Then, the decorative paper of the roll can be pulled to the next process. The adjustment component can adjust the distance between the two supports in real time according to the actual width of the decorative paper produced, so as to facilitate the placement of the roll with decorative paper on the device and quickly place and adjust it.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0018] This utility model provides an unwinding device, such as an unwinding device for decorative paper production.

[0019] The device includes a base 1 and a placement mechanism mounted on the base 1. The placement mechanism includes an adjustment component and a placement component mounted opposite to the adjustment component. To accommodate the device, annular grooves are provided at both ends of the roll of the decorative paper roll 12 so that the ends of the roll of the decorative paper roll 12 can be limited at the annular grooves.

[0020] Reference Figure 1 and Figure 2 The placement assembly is described in detail as follows: The placement assembly includes a bracket 6, an electric cylinder 7, a lifting seat 8, a roller 9, a rotating part 10, and a support plate 11. Two electric cylinders 7 are mounted on the bracket 6. There are also two lifting seats 8, which are fixedly mounted on the output end of the electric cylinders 7 and slide relative to each other along the support plate 11 fixed on the bracket 6. There are two rotating parts 10 mounted on the lifting seats 8 and fitted together with the roller 9 which is rotatably mounted on the lifting seats 8. The two ends of the decorative paper roll 12 are placed on two supports 6 for support. Then, the two ends of the roll are moved to the arc-shaped groove. Rollers 601 are rotatably installed on both sides of the arc-shaped groove of the support 6, which can be used for support. Then, the two sets of two electric cylinders 7 corresponding to the upper and lower parts of the placement components can be driven to push the lifting seat 8 to move along the support plate 11. Since the rotating part 10 is composed of a fixed column and a rotating ring, the rotating ring is rotatably set on the fixed column, and the fixed column is fixed at a right angle of the right angle plate of the lifting seat 8. The displacement is restricted, so the lifting seat 8 drives the rotating part 10 so that the rotating ring of the rotating part 10 can be embedded in the annular groove at the winding roller of the decorative paper roll 12, restricting both ends of the winding roller of the decorative paper roll 12. Then, the decorative paper of the decorative paper roll 12 can be pulled to the next process. There is a gap between the two rotating parts 10 in the same group, and the two groups of rotating parts 10 are arranged one above the other. The position of the lifting seat 8 can be adjusted by driving the electric cylinder 7, thereby adjusting the position of the rotating part 10 to restrict the upper and lower ends of the annular groove at the end of the decorative paper roll 12.

[0021] Since the rotating part 10 restricts the two ends of the roller of the decorative paper roll 12, a second roller 9 is provided. The second roller 9 consists of two rollers that are rotatably mounted on the other right-angle surface of the right-angle plate of the lifting seat 8 and located on both sides of the bottom of the rotating ring of the corresponding rotating part 10. The lower set of the second roller 9 can support the rotating part 10, thereby playing a role in stabilizing and limiting the position of the decorative paper roll 12. The roller 2 9 and the rotating part 10 are fitted together, and the roller 2 9 and the rotating part 10 do not affect the normal rotation. The roller 2 9 can assist the roller of the decorative paper roll 12 to rotate on the bracket 6. Similarly, the rotating part 10 is embedded in the annular groove at the end of the roller of the decorative paper roll 12, which restricts the movement of the roller of the decorative paper roll 12, but does not affect its normal rotation.

[0022] Reference Figure 1 The adjustment assembly is described in detail as follows: The adjustment assembly includes a motor 2, a bidirectional lead screw 3, a guide rail 4, and a slide block 5. The bidirectional lead screw 3 is fixedly installed at the output end of the motor 2. The guide rail 4 is positioned on both sides of the bidirectional lead screw 3. The slide block 5 is slidably arranged along the guide rail 4 and fixed to the bottom of the bracket 6. The distance between the two placement components can be adjusted by adjusting the components according to the length of the finished roll of decorative paper and its roll. First, the motor 2 drives the two supports 6 to move relative to each other through the bidirectional lead screw 3. The supports 6 can slide along the guide rail 4 through the slide block 5 until the distance between the two supports 6 is adjusted. The distance can be adjusted in real time according to the actual width of the decorative paper produced.

[0023] Furthermore, the device allows for the convenient placement and quick adjustment of a roll with decorative paper.

[0024] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
