Description

Technical Field

[0001] This utility model relates to the field of decorative paper processing technology, specifically to an unwinding mechanism for decorative paper processing. Background Technology

[0002] Decorative paper is a decorative material used on the surface of building materials, primarily for providing patterns and preventing the underlying adhesive from seeping through. During the processing of decorative paper, an unwinding mechanism is used to transport the decorative paper wound on rollers. Once the decorative paper on the rollers has been transported, the rollers need to be replaced.

[0003] As described in the publicly available Chinese patent application CN202222596122.4, a winding mechanism for decorative paper printing includes: "a support frame, a fixing plate, and a fixing assembly. The support frame is groove-shaped, the fixing plate is vertically fixed to both ends of the support frame, the fixing assembly is mounted on the fixing plate, and each side of the fixing plate has a connecting plate. A motor is connected to the connecting plate, and electric push rods are horizontally symmetrically arranged between the connecting plate and the fixing plate." This utility model belongs to the field of decorative paper technology, specifically providing a highly practical, simple-to-use winding mechanism for decorative paper printing that effectively fixes and installs rolls, facilitates unwinding operations, and improves work efficiency.

[0004] Through a search of the aforementioned patents, we found that since the rolls containing decorative paper need to be replaced with new ones after use, and the equipment is continuously dispensing decorative paper, when the rolls are almost empty, preparations for replacement should be made promptly. However, current technologies mostly rely on subjective judgment by the staff, which often fails to promptly ascertain the remaining amount of decorative paper on the rolls. If the staff is negligent or not near the equipment, and it is only discovered later that the rolls are empty and need replacement, a significant amount of time will be wasted due to the preparation work (such as moving the rolls containing decorative paper), thus affecting the feeding of subsequent equipment and the processing efficiency of the decorative paper.

[0005] Therefore, in response to the technical problems mentioned above in the existing technology, we designed a dewinding mechanism for decorative paper processing that can better replace the decorative paper take-up roller. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 A dewinding mechanism for decorative paper processing includes a base 1. A limiting groove 2 is provided on one side of the top of the base 1. A movable component driven by a servo motor 4 is slidably connected in the limiting groove 2. The movable component includes an adjusting plate 5 and a fixed frame 6. A warning flashing light 8 is installed on the top of the adjusting plate 5. A battery 17 is provided at the bottom of the fixed frame 6. A telescopic plate 601 is movably inserted inside the fixed frame 6. A movable plate 14 is fixed on one side of the telescopic plate 601. A contact rod 16 is fixed on one side of the movable plate 14. A contact block 18 is fixed on one side of the fixed frame 6 at a position corresponding to the contact rod 16. A rolling component 7 is provided on the other side of the telescopic plate 601. A second limiting groove 3 is provided on the other side of the top of the base 1. A support component driven by a servo motor 9 is slidably connected in the limiting groove 3. A dewinding component 13 that cooperates with the rolling component 7 is provided on the support component.

[0028] Please see Figure 4 and Figure 5In this embodiment, a spring 15 is fixed on the side of the movable plate 14 away from the telescopic plate 601, and the end of the spring 15 away from the movable plate 14 is fixed on the inner wall of the fixed frame 6. The movable plate 14 is slidably connected inside the fixed frame 6.

[0029] Specifically, the movable plate 14 can use the restoring force of the spring 15 to push the telescopic plate 601 to slide from the inside of the fixed frame 6 to the outside, so that the contact rod 16 can contact the contact block 18.

[0030] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the rolling assembly 7 includes two support plates 701 and a rotating roller 702. The two support plates 701 are fixed to the side of the telescopic plate 601 away from each other, and the rotating roller 702 is rotatably connected between the two support plates 701.

[0031] Specifically, the support plate 701 supports the rotating roller 702. After the rotating roller 702 comes into contact with the decorative paper on the decorative paper take-up roller 1301, it rotates in the form of rolling friction. On the one hand, it is always in contact with the decorative paper on the decorative paper take-up roller 1301 due to the restoring force of the spring 15, which facilitates subsequent feedback. On the other hand, the constant contact between the rotating roller 702 and the decorative paper can also provide a certain stability for the release of the decorative paper.

[0032] Please see Figure 4 and Figure 5 In this embodiment, the contact rod 16 is made of copper and is electrically connected to the warning flashing light 8 via a wire. The contact block 18 is made of copper and is electrically connected to the storage battery 17 via a wire.

[0033] Specifically, a charging port is provided on one side of the battery 17. It is rechargeable and provides power to the warning flash light 8. The warning flash light 8 emits a red flash, which can directly warn the workers in the workshop.

[0034] Please see Figure 1 In this embodiment, the servo motor 4 is installed on one side of the base 1. The power output shaft of the servo motor 4 extends through the limiting slide groove 2 and is connected to a single threaded rod 401. One end of the single threaded rod 401 is threaded through and fixed to the limiting slider 501 at the bottom of the adjusting plate 5 and is rotatably connected to one side of the inner wall of the limiting slide groove 2. The limiting slider 501 slides in the limiting slide groove 2 driven by the single threaded rod 401.

[0035] Specifically, after the servo motor 4 starts, it can drive the single threaded rod 401 to rotate. The threads on the single threaded rod 401 are in the same direction. It can drive the limit slider 501 to reciprocate in the limit groove 2 by rotating forward and backward. This will cause the adjusting plate 5, the fixed frame 6, the telescopic plate 601, the rolling assembly 7 and other structures to move away from or closer to the decorative paper take-up roller 1301. On the one hand, this is conducive to the replacement of the decorative paper take-up roller 1301. On the other hand, the position of the rolling assembly 7 from the decorative paper take-up roller 1301 can be adjusted according to the actual situation.

[0036] Please see Figure 1 and Figure 6 In this embodiment, the power output shaft of the servo motor 2 9 extends through the limiting slide groove 2 3 and is connected to a double threaded rod 901. The double threaded rod 901 has two opposite threads. The end of the double threaded rod 901 away from the servo motor 2 9 is rotatably connected to the inner wall of one side of the limiting slide groove 2 3. There are two sets of support components, which are respectively arranged on both sides of the limiting slide groove 2 3. Each set of support components includes a movable block 10 and a height adjustment block 11 on its top. The bottom of the two movable blocks 10 is fixed with a limiting slider 2 1001 that is slidably connected in the limiting slide groove 2 3. The two limiting sliders 2 1001 are respectively sleeved with the two opposite threads on the double threaded rod 901.

[0037] Specifically, after the servo motor 9 is started, the rotation of the double threaded rod 901 can drive the two limit sliders 1001 to move towards each other or away from each other. When they are close to each other, the decorative paper take-up roller 1301 can be installed using the height adjustment block 11. When they are far apart, the decorative paper take-up roller 1301 can be easily disassembled.

[0038] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, a cylinder 1002 is installed in the middle of the inner cavity of the movable block 10. The top of the power output shaft of the cylinder 1002 is fixed to the bottom of the height adjustment block 11. Limiting rods 1003 are also fixed on both sides of the top of the movable block 10. The limiting rods 1003 can move through the interior of the height adjustment block 11.

[0039] Specifically, by activating the cylinder 1002, the height adjustment block 11 can be pushed up, thereby raising the height of the decorative paper take-up roller 1301, which can leave enough space at the bottom of the decorative paper take-up roller 1301 for easy rotation. The limit rod 1003 designed in conjunction with it can further improve the stability of the height adjustment block 11 during movement.

[0040] Please see Figure 1 and Figure 6In this embodiment, a servo motor 3 12 is installed on one side of one height adjustment block 11. The power output shaft of the servo motor 3 12 passes through the height adjustment block 11 and is fixed to a docking shaft 1101. The side of the other height adjustment block 11 is also rotatably connected to a docking shaft 1101. An unwinding assembly 13 is provided between the two docking shafts 1101. The unwinding assembly 13 includes a decorative paper take-up roller 1301, a docking rod 1302, and decorative paper wound on the decorative paper take-up roller 1301. There are two docking rods 1302, which are respectively fixed at both ends of the decorative paper take-up roller 1301. The docking rods 1302 are inserted into the docking shaft 1101. The rod body of the docking rod 1302 is a hexagonal rod body. The inner wall of the docking shaft 1101 is provided with a hexagonal groove adapted to the docking rod 1302.

[0041] Specifically, by starting the servo motor 312, its power output shaft can drive the docking shaft 1101 connected to it to rotate, thereby driving the decorative paper take-up roller 1301 connected to the docking shaft 1101 to rotate, thus facilitating the decorative paper take-up roller 1301 to release decorative paper into subsequent equipment. At the same time, the docking shaft 1101 has a hexagonal groove, and the docking rod 1302 is a hexagonal rod, which can be easily inserted directly into the docking shaft 1101. After insertion, it achieves limit and positioning, ensuring the convenience of installation and the stability of the decorative paper take-up roller 1301 during rotation.

[0042] When using;

[0043] Driven by servo motor 12, the decorative paper take-up roller 1301 releases the decorative paper from the roller and feeds it into the subsequent processing equipment. As the decorative paper is continuously released, the amount of decorative paper remaining on the roller 1301 decreases, meaning the thickness of the decorative paper on the roller 1301 becomes thinner. When the thickness of the decorative paper on the roller 1301 becomes thinner, the rolling assembly 7 and the telescopic plate 601 are further moved to one side of the roller 1301 by the reset action of the spring 15. (The rotating roller 702 included in the rolling assembly 7 is always in rolling contact with the decorative paper on the surface of the roller 1301.) When the contact rod 16 contacts the contact block 18, the circuit between the warning flash light 8 and the storage battery 17 is connected, which can light up the warning flash light 8. The flashing effect of the warning flash light 8 can remind nearby staff that the decorative paper on the decorative paper take-up roller 1301 is about to run out and preparations should be made to replace the decorative paper take-up roller 1301. After the replacement is completed, the decorative paper on the newly replaced decorative paper take-up roller 1301 has thickness and can be applied to the rolling assembly 7 and the telescopic plate 601 again, so that the contact rod 16 moves away from the contact block 18 and enters the next replacement cycle. In the end, the unwinding mechanism can make timely judgments on the replacement of the decorative paper take-up roller 1301.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
