Description

Technical Field

[0001] The present application relates to the field of film feeding device design, and in particular to a hot stamping film feeding device. Background Art

[0002] Hot stamping has a metallic luster and bright colors, and has a good decorative effect. It is widely used in high-end and exquisite packaging decoration, trademarks, book covers and other printed materials, as well as household appliances, architectural decorations, crafts and cultural products. This process can be applied to materials such as paper, leather, silk fabrics, and plastics. Hot stamping can make the product have a high-end texture: at the same time, due to its excellent physical and chemical properties, it also plays a role in protecting printed materials.

[0003] During hot stamping production, plastic film needs to be continuously fed into the hot stamping machine, and the plastic film then contacts the pattern roller to print ink on the plastic film. When a roll of plastic film is used up, it needs to be replaced with a new one. The existing method of fixing the film roll is that two shafts are inserted from both ends of the film roll into the holes of the central shaft of the film roll, thereby supporting the film roll by contacting both ends of the film roll. This fixing method is easy to cause the middle part of the film roll to bend over the ground or even touch the ground when the width of the film roll is large, resulting in wrinkles on the film surface and scratches from rubbing against the ground, thereby reducing the subsequent hot stamping effect.

[0027] Reference Figure 1-3 ,

[0028] A hot stamping film feeding device comprises: a bracket 1, a fixed block 2, a film roller 3 and a power assembly 4. The bracket 1 is placed on the ground, and the fixed block 2 is detachably connected to the upper end of the bracket 1 by screws. The fixed block 2 forms a through hole, and two groups of fixed blocks 2 are provided. The through holes of the two groups of fixed blocks 2 are coaxial, and the two ends of the film roller 3 are inserted into the through holes of the fixed block 2 and are rotatably connected with the through holes. The film roller 3 is used to be inserted into the hole of the axis of the film roll to form support for the film roll. The power assembly 4 is connected to the film roller 3 to form a transmission relationship, so that the film roller 3 rotates around its own axis, thereby conveying the film in the film roll to the subsequent hot stamping process.

[0029] Specifically, it also includes: a pressure roller 5. The pressure roller 5 is placed on one side of the film roller 3, the axis of the pressure roller 5 is parallel to the axis of the film roller 3, and the two ends of the pressure roller 5 are rotatably connected to the bracket 1. When the film roll rotates to transport the film outward, in order to prevent the film from being broken, the film output speed is usually faster than the film hot stamping speed, so that the film will partially sag after being output from the film roll, and it is easy to hook the debris on the ground. There is a distance between the pressure roller 5 and the film roller 3. The film output from the film roll bypasses the lower end of the pressure roller 5. The pressure roller 5 provides a downward reaction force to the film, thereby tightening the film to prevent it from being hooked.

[0030] Specifically, the power assembly 4 includes: a power member 6, a small pulley 7, a belt 8, a large pulley 9, a transmission shaft 10, a first gear 11 and a second gear 12. The power machine uses an electric motor, the power member 6 is placed on the ground, the output end of the power member 6 is fixedly connected to the small pulley 7 through a flat key, the large pulley 9 is sleeved and fixed on the transmission shaft 10, the belt 8 sleeves the small pulley 7 and the large pulley 9 to form a reduction transmission, the first gear 11 is also sleeved and fixed on the transmission shaft 10, the second gear 12 is sleeved on one end of the film roller 3, and the first gear 11 and the second gear 12 are meshed. Start the power member 6, the power member 6 drives the small pulley 7 to rotate, the small pulley 7 drives the large pulley 9 to rotate through the belt 8, the large pulley 9 drives the transmission shaft 10 to rotate, the transmission shaft 10 drives the first gear 11 to rotate, the first gear 11 drives the meshed second gear 12, and the second gear 12 drives the film roller 3 to rotate to deliver the film. When the film roll needs to be replaced, the user removes the screws on the fixing block 2, removes the film roller 3 together with the second gear 12 from the bracket 1, removes the fixing block 2 away from the second gear 12 from the end of the film roller 3, and then puts the film roll on the film roller 3.

[0031] In another embodiment, the bracket 1 forms a sliding groove 13, and both ends of the pressure roller 5 are inserted into the sliding groove 13. The sliding groove 13 is inclined relative to the ground, and the height of the end of the sliding groove 13 close to the film roller 3 is higher than the height of the end away from the film roller 3. Under the action of gravity, the pressure roller 5 is initially located at the end of the sliding groove 13 away from the film roller 3 to press the film. When more and more film is fed out of the film roll, the diameter of the film roll gradually decreases, while the rotation angular velocity of the film roller 3 remains unchanged, so that the length of the film output per unit time becomes smaller, that is, the output film will gradually tighten, and the tightened film will push the pressure roller 5 along the sliding groove 13 close to the film roller 3, so that the length of the film tightened by the pressure roller 5 is reduced, and the film is prevented from breaking.

[0032] Specifically, the upper portion of the sliding groove 13 close to one end of the film roller 3 is open, so that the user can easily put the pressing roller 5 into the sliding groove 13 from the open portion.

[0033] Specifically, the end of the film roller 3 is inserted into the through hole from one side and then extends out of the through hole from the other side, so that after the fixing block 2 is removed from the bracket 1, the user can grasp the end of the film roller 3 to lift the film roller 3 and replace the film roll.

[0034] Specifically, one end of the transmission shaft 10 is rotatably connected to the bracket 1 through a bearing, the other end of the transmission shaft 10 is sleeved with a large pulley 9 and fixedly connected through a flat key, the middle part of the transmission shaft 10 is sleeved with a first gear 11 and fixedly connected through a flat key, and the bracket 1 supports the large pulley 9 and the first gear 11 through the transmission shaft 10.
