Description
Technical Field
[0001] The utility model relates to a hot stamping machine, in particular to an unwinding device of a hot stamping machine. Background Art
[0002] A hot stamping machine is a special device for hot stamping products. Its working principle is to unwind the hot stamping foil through an unwinding device and pull it between the upper and lower templates. After that, when the paper to be hot stamped is also sent between the upper and lower dies, the upper and lower dies act to tightly press the paper and the hot stamping foil together to achieve hot stamping processing. In the actual use process, the problems existing in the pulling process of the hot stamping foil are as follows: 1. During the pulling process of the hot stamping foil, local position deviation may occur, some positions of the hot stamping foil may be wrinkled, and the local tension will also change, affecting the subsequent hot stamping quality. Generally, the unwinding device of the hot stamping foil is arranged close to the upper die, and the pulling space of the hot stamping foil is very narrow. Generally, it is difficult to set up a deviation rectifying device to rectify the hot stamping foil; 2. Usually, a foil passing roller needs to be set up to realize the positioning and pulling of the hot stamping foil. In the actual use process, the foil passing roller is generally rotatably arranged or fixedly arranged. When the foil passing roller is rotatably arranged, the hot stamping foil will drive the foil passing roller to rotate through friction. If the passing hot stamping foil is narrow, it is relatively easy to be pulled. Coupled with the rotation of the foil passing roller, the hot stamping foil may become loose when passing through this place, resulting in the inability to ensure that the hot stamping foil is straight when sent to the hot stamping station, affecting the hot stamping quality; when the foil passing roller is fixedly arranged, if the passing hot stamping foil is wide, it is relatively difficult to be pulled. When the hot stamping foil passes through the foil passing roller, due to the large contact area between the hot stamping foil and the foil passing roller, the friction force is also large, which is easy to cause the hot stamping foil to be over-stretched and deformed, affecting the subsequent hot stamping quality. Content of the Utility Model
[0003] In view of the deficiencies of the background art, the technical problem to be solved by the utility model is to provide an unwinding device of a hot stamping machine for solving the above problems.
[0004] For this reason, the utility model is realized by the following scheme:

[0008] The first movable block is arranged in the first movable groove on the first mounting seat. The first movable adjusting component includes a first adjusting bolt which is screwed on the first mounting seat. The first adjusting bolt abuts against the outer side wall of the first movable block. It further includes a second adjusting bolt which is screwed with the outer side wall of the first movable block.

[0018] As shown in the figure, a unwind device of a hot stamping machine disclosed by the present utility model includes an unwind shaft 1. The base material unwound on the unwind shaft 1 bypasses a foil passing roller 3. One end of the foil passing roller 3 is arranged on a first movable block 9, and the other end is arranged on a second movable block 14. A locking component is correspondingly arranged for the foil passing roller 3. The locking component can restrict the rotation of the foil passing roller 3 or release the foil passing roller 3 to enable it to rotate self. The first movable block 9 is arranged on a first mounting seat 4, and a first movable adjusting component can drive the first movable block 9 to act to adjust the position of one end of the foil passing roller 3. The second movable block 14 is arranged on a second mounting seat 12, and a second movable adjusting component can drive the second movable block 14 to act to adjust the position of the other end of the foil passing roller 3.
[0019] Further, both ends of the foil passing roller 3 are respectively rotatably arranged on the first movable block 9 and the second movable block 14. A locking component is correspondingly arranged for the foil passing roller 3. The locking component can restrict the rotation of the foil passing roller 3 or release the foil passing roller 3 to enable it to rotate self, realizing the switching between the rotation and locking of the foil passing roller 3. Specifically, the locking component includes a locking bolt 10 screwed on the first and / or second mounting seat. A locking surface 11 is arranged on the outer side wall of the foil passing roller 3. The locking bolt 10 can tightly press on the locking surface 11 to restrict the rotation of the foil passing roller. By controlling the rotation of the locking bolt 10 to separate from the foil passing roller 3, the foil passing roller can be released to enable it to rotate self.
[0020] Further, it further includes two positioning plates 2 arranged at intervals. The positioning plates 2 are slidably clamped on the unwind shaft 1. The positioning plates 2 can be slid to the required positions according to the width of the hot stamping foil, and then the two ends of the hot stamping foil are positioned and blocked to ensure that it will not shift left and right during unwinding.
[0021] Further, the first movable block 9 is arranged in the first movable slot 8 on the first mounting seat 4. The first movable adjustment component includes a first adjustment bolt 7 which is screwed on the first mounting seat 4 and abuts against the outer side wall of the first movable block 9. It further includes a second adjustment bolt 6 which is screwed with the outer side wall of the first movable block 9. The second adjustment bolt 6 passes through a first relief hole 18 on the first mounting seat 4. The aperture of the first relief hole 18 is larger than the diameter of the second adjustment bolt 6. A first nut 5 is screwed on the second adjustment bolt 6, and the first nut 5 can abut against the first mounting seat 4. With the above structure, the first adjustment bolt 7 can be rotated first to separate it from the first movable block 9, and then the first nut 5 is rotated. At this time, one end of the first nut 5 abuts against the first mounting seat 4, which can drive the second adjustment bolt 6 to move, and then the first movable block 9 is moved, thereby driving one end of the foil passing roller 3 to move forward; or first reverse the first nut 5 to make it move on the second adjustment bolt 6 and separate from the first mounting seat 4 by an appropriate distance, and then rotate the first adjustment bolt 7 to rotate and abut against the first movable block 9 to move backward until the first nut 5 abuts against the first mounting seat 4, thereby driving one end of the foil passing roller 3 to move backward.
[0022] Further, the second movable block 14 is arranged in the second movable slot 13 on the second mounting seat 12. The second movable adjustment component includes a third adjustment bolt 15 which is screwed on the second mounting seat 12 and abuts against the outer side wall of the second movable block 14. It further includes a fourth adjustment bolt 17 which is screwed with the outer side wall of the second movable block 14. The fourth adjustment bolt 17 passes through a second relief hole 19 on the second mounting seat 12. The aperture of the second relief hole 19 is larger than the diameter of the fourth adjustment bolt 17. A second nut 16 is screwed on the fourth adjustment bolt 17, and the second nut 16 can abut against the second mounting seat 12. With the above structure, the third adjustment bolt 15 can be rotated first to separate it from the second movable block 14, and then the second nut 16 is rotated. At this time, one end of the second nut 16 abuts against the second mounting seat 12, which can drive the fourth adjustment bolt 17 to move, and then the second movable block 14 is moved, thereby driving the other end of the foil passing roller 3 to move forward; or first reverse the second nut 16 to make it move on the fourth adjustment bolt 17 and separate from the second mounting seat 12 by an appropriate distance, and then rotate the third adjustment bolt 15 to rotate and abut against the second movable block 14 to move backward until the second nut 16 abuts against the second mounting seat 12, thereby driving the other end of the foil passing roller 3 to move backward.
[0023] It should be noted that the moving strokes of the first and second movable blocks are relatively small. Since the diameters of the first and second relief holes on the first and second mounting seats are larger than the diameters of the second and fourth adjusting bolts, when the first and second movable blocks act, the second and fourth adjusting bolts will not be stuck with the first and second mounting seats. In addition, according to the adjustment and use requirements, the adjusting bolts can also be set at different angles, so as to realize the moving adjustment of the foil passing roller in different directions.
[0024] The working principle of the present utility model is as follows: The hot stamping foil is unrolled on the unwinding reel 1 and passes through the foil passing roller 3, and then is sent between the upper and lower dies, waiting for hot stamping processing. When it is found that one side of the hot stamping foil is offset or the tension is insufficient, the position of one end of the foil passing roller 3 can be adjusted by controlling the rotation of the corresponding adjusting bolt and nut, so as to achieve the effects of deviation correction and local tension adjustment. When the width of the unrolled hot stamping foil is small, the locking component can be controlled to lock the foil passing roller 3 so that it cannot rotate. At this time, the friction force between the foil passing roller 3 and the hot stamping foil is appropriate, avoiding situations such as insufficient tension and looseness of the hot stamping foil. When the width of the unrolled hot stamping foil is large, the locking component can be controlled to release the foil passing roller 3, so that the foil passing roller 3 can rotate automatically, avoiding the situation that the hot stamping foil is stretched due to excessive friction force between the foil passing roller 3 and the hot stamping foil, and ensuring that the hot stamping foil can be sent to the subsequent hot stamping station smoothly and steadily.
[0025] With this structure of the present utility model, by rotatably arranging the two ends of the foil passing roller on the first and second movable blocks, and by respectively controlling the activities of the first and second movable blocks, the two ends of the foil passing roller can be independently adjusted back and forth respectively, so as to realize the deviation correction and tension adjustment of the hot stamping foil during unwinding, avoiding problems such as offset, unbalanced tension and wrinkles of the hot stamping foil during unwinding, ensuring that the subsequent hot stamping foil can be accurately sent to the hot stamping station for hot stamping operation, and ensuring the hot stamping quality. At the same time, a locking component is provided, which can switch the rotation and fixed state of the foil passing roller according to the size of the conveyed hot stamping foil, so that the hot stamping foil can be sent to the hot stamping station smoothly and flatly for hot stamping operation. At the same time, the overall structure is very delicate, adapting to the defect that the installation space of the unwinding device is small.
