Description

Technical Field

[0001] This utility model relates to the field of laser paper technology, specifically a positioning roll laser paper drying device. Background Technology

[0002] Laser paper (also known as holographic paper) is a special paper or film material with a laser holographic effect on its surface, and it is widely used in packaging, printing, decoration and anti-counterfeiting fields.

[0003] When finished laser paper, which has been wound on a roll for a long time, is unwound, it may curl due to uneven winding tension or insufficient cooling and curing during the production process, resulting in an imbalance in the internal stress distribution of the material. Additionally, during long-term storage, the inner and outer layers of the roll may have different moisture absorption / drying rates, and the laser paper substrate may develop a "memory curvature" under long-term winding. This affects the actual use effect. To address this, we propose a positioning roll laser paper heat drying device to flatten it. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-5 A positioning roll laser paper heating and drying device includes: a base 1, a heating and drying component 2 and an auxiliary component 4 respectively disposed on the base 1, a roll body 31 connected to the base 1 through the auxiliary component 4, and a laser paper body 3 disposed on the outer surface of the roll body 31.

[0024] The hot drying assembly 2 includes a guide post 21, a lower leveling block 26, and a damping rod 27 fixedly installed on the top surface of the base 1. A slide block 22 is slidably mounted on the guide post 21. A weight-increasing block 23 is fixedly mounted on the upper surface of the slide block 22. A hot drying fan 24 is fixedly mounted in the center of the slide block 22. An upper leveling block 25 and a boss 29 are fixedly mounted on the lower surface of the slide block 22. A guide roller 28 is rotatably mounted on the boss 29. The central axis of the upper leveling block 25 is parallel to that of the lower leveling block 26. The central axes coincide, and both the upper leveling block 25 and the lower leveling block 26 can contact the laser paper body 3. The end of the laser paper body 3 passes around the guide roller 28 in sequence and then passes through the space between the upper leveling block 25 and the lower leveling block 26. The movable end face of the damping rod 27 can contact the slide block 22. The boundaries of the upper leveling block 25 and the lower leveling block 26 are both rounded and smooth to prevent the boundaries of the upper leveling block 25 and the lower leveling block 26 from being too sharp and to avoid damage to the laser paper body 3.

[0025] Auxiliary component 4 includes a fixing plate 45 fixedly installed on the side of base 1 and a slide rod 41 slidably connected to base 1. A fixing rod 48 is fixedly installed on the side of fixing plate 45, and a screw 46 is threadedly connected to fixing plate 45. A slide plate 47 is slidably mounted on fixing rod 48. A bearing 412 is provided on the side of slide plate 47, and a clamping block 411 is rotatably connected to slide plate 47 through bearing 412. A protrusion on the side of clamping block 411 can be inserted into the drum body 31. A U-shaped block 42 is fixedly installed at the end of slide rod 41. A connecting rod 44 is slidably mounted on U-shaped block 42. A pressure plate 43 and a clamping plate 410 are fixedly installed at both ends of connecting rod 44, respectively. A spring 49 is fixedly installed on the side of clamping plate 410, and the spring 49 is located away from clamping plate 410. The end is fixedly connected to the U-shaped block 42. The clamping plate 410 can cooperate with the side wall of the U-shaped block 42 to increase the contact area with the laser paper body 3, so that the laser paper body 3 is subjected to uniform force. This prevents the user's finger from having a small contact area with the laser paper body 3, which would affect the flatness of the laser paper body 3. This ensures that the overall structure is designed for the flatness of the laser paper body 3. The slide rod 41 has an L-shaped structure design, and a limit block is provided at the end of the slide rod 41 away from the U-shaped block 42. There are two fixing rods 48, and the number of fixing plates 45 is the same as the number of fixing rods 48. The two fixing plates 45 are fixedly set at both ends of the fixing rods 48. The slide plate 47 has through holes for the fixing rods 48 to pass through, and there are also two through holes.

[0026] Working principle: A guide post 21 is fixed on the base 1, and a slide block 22 is slidably connected to the guide post 21. A hot air blower 24 is fixedly installed in the center of the slide block 22. Rotating the screw 46, which is threadedly connected to the fixed plate 45, pushes the slide plate 47 to slide on the fixed rod 48 fixed on the fixed plate 45. This causes the clamping block 411, which is rotatably connected to the slide plate 47 via the bearing 412, to abut against the roll body 31. The clamping blocks 411 on both sides of the roll body 31 cooperate with each other to clamp the roll body 31. At this time, the roll body 31 is still rotatable. Pushing the slide block 22 upwards creates a gap between the upper leveling block 25 and the lower leveling block 26. Pulling the laser paper body 3 causes it to pass over the guide roller 28 and be positioned between the upper leveling block 25 and the lower leveling block 26. Releasing the slide block 22 releases the weight of the slide block 22 itself. Under the added gravity of the weight and the weight block 23, the slide block 22 and the upper leveling block 25 slide downwards. When the slide block 22 slides down to contact the damping rod 27, it will slow down the descent speed of the upper leveling block 25 until the upper leveling block 25 and the lower leveling block 26 cooperate to clamp the laser paper body 3. Then the hot air blower 24 is started to heat the laser paper body 3. At this time, the upper leveling block 25 and the lower leveling block 26 press against each other to flatten the laser paper body 3. When it is necessary to pull out the flattened laser paper body 3, the pressure plate 43 is pressed down, and the clamping plate 410, which is fixedly connected to the pressure plate 43 through the connecting rod 44, slides down together. At the same time, the clamping plate 410 cooperates with the U-shaped block 42 to clamp the laser paper body 3. Then, by pulling the U-shaped block 42, the flattened laser paper body 3 can be pulled out.
