Description
Technical Field
[0001] This utility model belongs to the field of packaging paper production technology, specifically relating to an anti-counterfeiting embossing device for aluminum foil composite paper. Background Technology
[0002] Aluminum foil composite paper is a common packaging material composed of multiple layers of film, providing excellent moisture protection, oxidation prevention, and gas barrier properties during the packaging process. The production process of aluminum foil composite paper mainly includes coating, lamination, drying, and slitting. First, adhesive is applied to the paper, then aluminum foil is placed on top, and the layers are laminated using a pressing machine. Next, the laminated material is placed in a drying chamber for drying. Finally, the dried material is slitted to the required dimensions. Currently, in the aluminum foil paper production process, in order to improve the grade and anti-counterfeiting performance of aluminum foil composite paper, it is necessary to perform anti-counterfeiting embossing treatment on the aluminum foil composite paper before slitting. In existing technology, the anti-counterfeiting embossing treatment of aluminum foil composite paper is generally carried out using an embossing machine. The existing embossing machine includes two upper embossing rollers and a lower embossing roller, which are spaced apart vertically. The upper and lower embossing rollers are processed with matching embossing patterns. When the composite paper passes between the upper and lower embossing rollers, the squeezing pressure of the upper and lower embossing rollers can emboss the aluminum foil composite paper. The above-mentioned embossing machine has the following shortcomings during use: First, the dried aluminum foil composite paper directly enters the upper and lower embossing rollers, causing misalignment during transport. This prevents the aluminum foil composite paper from moving in a straight line during embossing, resulting in misaligned patterns and affecting the aesthetics of the aluminum foil composite paper. Second, the existing upper and lower embossing rollers have fixed installation positions and a fixed spacing, which cannot meet the embossing requirements of aluminum foil composite paper of different thicknesses, resulting in poor adaptability. Therefore, it is objectively necessary to develop an aluminum foil composite paper anti-counterfeiting embossing device with a reasonable structure that can prevent aluminum foil misalignment and improve the adaptability of the device. Summary of the Invention
[0003] The purpose of this invention is to provide an aluminum foil composite paper anti-counterfeiting embossing device with a reasonable structure that can prevent aluminum foil misalignment and improve the adaptability of the device.
[0004] The purpose of this utility model is achieved as follows: it includes a mounting frame and a feeding guide mechanism, an embossing mechanism, and a discharging guide mechanism that are sequentially mounted on the mounting frame. An anti-deviation mechanism is installed on the mounting frame between the embossing mechanism and the feeding guide mechanism. The anti-deviation mechanism includes a first lifting device and a translation driver. The translation driver is mounted on the mounting frame via the first lifting device. An L-shaped guide plate is symmetrically mounted on the translation driver. The embossing mechanism includes an upper embossing roller and a lower embossing roller arranged at intervals. The lower embossing roller is rotatably mounted on the lower part of the mounting frame. A first motor that is rotatably connected to the lower embossing roller is mounted on the mounting frame. A second lifting device is mounted on the upper part of the mounting frame, and the upper embossing roller is mounted on the second lifting device.
[0005] Compared with existing technologies, the advantages of this device are as follows: First, the anti-deviation mechanism guides the aluminum foil composite paper entering the embossing mechanism, preventing deviation during transport and ensuring the paper remains in a straight line. This allows for precise embossing, preventing the pattern from shifting or tilting, thus improving the embossing quality. Second, the structure of the embossing mechanism is optimized. The upper embossing roller can be raised and lowered using a second lifting adjuster, allowing for timely adjustment of the distance between the upper and lower rollers. By adjusting the distance, the embossing requirements of aluminum foil composite paper of different thicknesses can be met, effectively improving the device's adaptability. This device boasts a reasonable structure, excellent embossing effect, and strong adaptability, making it easy to promote and use. Attached Figure Description

Detailed Implementation
[0012] The present invention will be further described below with reference to the accompanying drawings, but this description is not intended to limit the present invention in any way. Any changes or improvements made based on the teachings of the present invention shall fall within the protection scope of the present invention.
[0013] like Figures 1-5 As shown, this utility model includes a mounting frame 1 and a feeding guide mechanism 2, an embossing mechanism 3, and a discharging guide mechanism 4 sequentially mounted on the mounting frame 1. The feeding guide mechanism 2 and the discharging guide mechanism 4 are structures used in the prior art, mainly including an upper guide roller and a lower guide roller symmetrically arranged vertically. One end of the lower guide roller is equipped with a driver to drive its rotation. An anti-deviation mechanism 5 is mounted on the mounting frame 1 between the embossing mechanism 3 and the feeding guide mechanism 2. The anti-deviation mechanism 5 includes a first lifting device and a translation driver. The first lifting device can drive the translation driver to move up and down to adjust its relative position with the embossing mechanism. The translation driver is mounted on the mounting frame 1 through the first lifting device. L-shaped guide plates 51 are symmetrically mounted on the translation driver. The translation driver can drive... Two L-shaped guide plates 51 move in the same direction or in opposite directions to meet the guiding requirements of aluminum foil composite paper of different widths. The embossing mechanism 3 includes an upper embossing roller 31 and a lower embossing roller 32 arranged at intervals. The upper embossing roller 31 and the lower embossing roller 32 are structures used in the prior art. According to the type of embossing pattern, mutually compatible embossing patterns are pre-processed on the surfaces of the upper embossing roller 31 and the lower embossing roller 32. The lower embossing roller 32 is rotatably mounted on the lower part of the mounting frame 1. The mounting frame 1 is equipped with a first motor 33 that is rotatably connected to the lower embossing roller 32. The first motor 33 is a structure used in the prior art, and finished products can be directly purchased according to the needs of use. A second lifter is installed on the upper part of the mounting frame 1, and the upper embossing roller 31 is mounted on the second lifter.
[0014] The working process of this device is as follows: The aluminum foil composite paper to be embossed is passed through the feeding guide mechanism 2, and then through the two L-shaped guide plates 51, entering between the upper embossing roller 31 and the lower embossing roller 32. Simultaneously, the first motor 33 is started, driving the lower embossing roller 32 to rotate, thus transmitting the aluminum foil composite paper. During the transmission between the upper and lower embossing rollers 31 and 32, the aluminum foil composite paper is pressed by the squeezing action of the rollers, resulting in the desired pattern. After the patterned aluminum foil composite paper passes through the discharge guide mechanism 4, continuous embossing of the aluminum foil composite paper is achieved. Furthermore, before embossing, the distance between the upper and lower embossing rollers 31 and 32 can be adjusted according to the thickness of the aluminum foil composite paper. During adjustment, the second lifting mechanism is activated. The second lifting device can drive the upper embossing roller 31 to move up and down reciprocally. The up and down movement of the upper embossing roller 31 can adjust the distance between it and the lower embossing roller 32. After the distance between the upper embossing roller 31 and the lower embossing roller 32 is adjusted, the first lifting device drives the translation driver to move up and down. After moving until the height of the two L-shaped guide plates 51 matches the distance between the upper embossing roller 31 and the lower embossing roller 32, the translation driver is controlled to drive the two L-shaped guide plates 51 to move in the same direction or in opposite directions according to the width of the aluminum foil composite paper. The distance between the two L-shaped guide plates 51 is adjusted to match the width of the aluminum foil composite paper. The aluminum foil composite paper is transferred between the feeding guide mechanism 2 and the embossing mechanism 3 through the two guide plates. This can guide the aluminum foil composite paper and prevent deviation during the transfer process, which is beneficial to improving the embossing quality of the aluminum foil composite paper.
[0015] Furthermore, the first lifting device includes a lifting cylinder 52 and a movable plate 53. The mounting frame 1 has first sliding grooves 54 machined along its vertical direction on both sides. The movable plate 52 is slidably installed within the first sliding grooves 54. The lifting cylinder 52 is fixedly installed on the outside of both sides of the mounting frame 2, and the movable end of the lifting cylinder 52 is fixedly connected to the top of the movable plate 53. The lifting cylinder is a structure used in the prior art; finished products can be directly purchased based on the stroke size. The translation drive includes a rotating rod 55 and a second motor 56. The second motor 56 is a structure used in the prior art; finished products can be directly purchased based on the power required. Support plates 57 are symmetrically installed at the bottom of the first lifting device. The rotating rod 55 is rotatably installed between the two support plates 57. The second motor 56 is installed on the outside of one of the support plates 57 and rotatably connected to the rotating rod 55. The rotating rod 55 has two sections of threaded adjustment with opposite directions. The L-shaped guide plate 51 has a threaded section, and a slider 58 is screwed onto the threaded section. The vertical section of the L-shaped guide plate 51 is fixedly connected to the bottom of the slider 58. In use, the lifting cylinder 52 is activated, and the movable end of the lifting cylinder 52 is extended or retracted, which drives the movable plate 52 and the translation starter to move up and down along the first slide groove 54, thereby realizing the up and down adjustment of the L-shaped guide plate 51. After the height of the two L-shaped guide plates 51 is adjusted, the distance between the two L-shaped guide plates 51 is adjusted according to the width of the aluminum foil composite paper. During adjustment, the second motor 56 is activated, and the second motor 56 drives the rotating rod 55 to rotate forward or backward. During the rotation of the rotating rod 55, the two sliders 58 can move in the same direction or backward on the corresponding threaded section. During the movement of the two sliders 58, the two L-shaped guide plates 51 can move in the same direction or backward, thereby realizing the adjustable distance between the two L-shaped guide plates 51.
[0016] Preferably, in order to ensure smoother conveying of aluminum foil composite paper between the two L-shaped guide plates 51, a plurality of ball bearings 59 are slidably installed on the upper surface of the horizontal section of the L-shaped guide plate 51. The ball bearings 59 roll on the L-shaped guide plate 51, and the force of the rolling of the ball bearings 59 can make the conveying of aluminum foil composite paper more stable and smooth.
[0017] Furthermore, the second lifting device includes a drive motor 34, a transmission screw 35, and a guide rod 36. The drive motor 34 is a structure used in the prior art, and finished products are directly purchased according to the power required. A second sliding groove 37 is machined on the mounting frame 1 along its vertical direction. A first adjusting box 38 and a second adjusting box 39 are respectively installed on both sides of the mounting frame outside the second sliding groove 37. The transmission screw 35 is rotatably installed in the first adjusting box 38. The drive motor 34 is installed on the first adjusting box 38. A driving bevel gear 310 is installed on the output shaft of the drive motor 34. A driven bevel gear 311 that meshes with the driving bevel gear 310 is installed at the lower end of the transmission screw 35. A threaded sleeve 312 is slidably installed on the transmission screw 35. The guide rod 36 is fixedly installed in the second adjusting box 39. A guide sleeve 313 is slidably installed on the guide rod 36. The roller shafts at both ends of the upper embossing roller 31 are slidably installed in the corresponding second sliding grooves 37. A guide sleeve 313 is installed on the roller shaft located in the first adjusting box 38. The first bushing 314 is fixedly connected to the threaded sleeve 312 via a connecting rod. A second bushing 315 is installed on the roller shaft located inside the second adjusting box 39. The second bushing 315 is fixedly connected to the guide sleeve 313 via a connecting rod. When adjustment of the upper embossing roller 31 is required, the drive motor 34 is turned on. The drive motor 34 drives the active bevel gear 310 to rotate. The rotation of the active bevel gear 310 drives the lead screw 35 to rotate. During the rotation of the lead screw 35, the threaded sleeve... The threaded sleeve 312 moves along the transmission screw 35 and simultaneously drives the guide sleeve 313 to move along the guide rod 36. During the synchronous movement of the threaded sleeve 312 and the guide sleeve 313, the first bushing 314, the upper embossing roller 31, and the second bushing 315 can move synchronously along the second slide groove 37, thereby realizing the adjustment of the distance between the upper embossing roller 31 and the lower embossing roller 31. This structure can realize the adjustment of the up and down movement of the upper embossing roller 31 by controlling the forward or reverse rotation of the drive motor 34, which is relatively convenient to use.
[0018] Preferably, to ensure smoother vertical movement of the upper embossing roller 31, two guide rods 36 are provided, symmetrically arranged on both sides of the second bushing 315. The transmission screw 35 is located on one side of the first bushing 314. A sliding rod 316 symmetrical to the transmission screw 35 is installed in the first adjusting box 38 on the other side of the first bushing 314. An auxiliary sliding sleeve 317 is slidably mounted on the sliding rod 316. The auxiliary sliding sleeve 317 is connected and fixed to the first bushing 314 via a connecting rod. One end of the upper embossing roller 31 moves between the two guide rods 36, and the other end moves between the transmission screw 35 and the sliding rod 316, effectively enhancing the connection strength between the upper embossing rollers 31 and improving the stability of the upper embossing roller 31's vertical movement.
