Description

Technical Field

[0001] This utility model relates to a vacuum bag embossing device, specifically an embossing device for vacuum bag processing, belonging to the field of vacuum bag technology. Background Technology

[0002] Vacuum bags, also known as personal moisture-proof bags, aluminum foil bags, or aluminum-plastic composite bags, are generally made of PET / AL / CPE or PET / NY / AL / CPE. PET offers good printing results, NY has low oxygen permeability, AL provides strong barrier properties and is opaque, and CPE is used for the inner packaging layer. The adhesive used is water-soluble (more hygienic, environmentally friendly, and leaves no solvent residue). This product has excellent antistatic, oxygen-barrier, shielding, moisture-proof, and light-blocking functions, as well as excellent heat-sealing properties. Embossing devices for vacuum bag processing are specialized equipment used to press patterns onto the surface of vacuum bags.

[0003] In the prior art, a vacuum bag embossing device is disclosed in patent announcement number CN209580668U, belonging to the field of vacuum bag processing technology. This vacuum bag embossing device includes a housing, with four fixing plates fixedly connected to the left side of the housing. Each of the two fixing plates has a first bearing snapped onto its opposite side. The two first bearings are respectively sleeved on both ends of the embossing roller. The two embossing rollers are symmetrical vertically, and the opposite sides of the two embossing rollers overlap with the outer surface of the vacuum bag body.

[0004] After the embossing process is completed, the embossing device used in vacuum bag processing needs to cool the surface of the vacuum bag by spraying liquid and dry the surface of the vacuum bag by using a fan. Currently, the spray nozzle and air duct for spraying liquid are all located on one side of the vacuum bag surface. This results in poor cooling and drying effect on the other side of the vacuum bag, thus reducing the uniformity of cooling on the surface of the vacuum bag, which affects the quality of the finished vacuum bag and also reduces the drying effect on the surface of the vacuum bag.

[0018] This utility model provides an embossing device for vacuum bag processing.

[0019] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The device includes a main body 1, with embossing components 2 and winding components 3 respectively on both sides of the main body 1. A water tank 4 and a drying component 5 are installed on the bottom wall inside the main body 1. Two guide rollers 6 are rotatably connected to the inner wall of the main body 1. The guide rollers 6 are located directly above the water tank 4. A guide roller 7 is rotatably connected to the inner wall of the water tank 4. Specifically, the device body 1 is placed on one side of the vacuum bag conveying or processing equipment. The winding assembly 3 and the vacuum bag conveying or processing equipment are existing technologies and usage methods, which will not be described in detail in this application. After the vacuum bag is conveyed or processed, it will pass through the embossing assembly 2 and then through the interior of the device body 1. Finally, the vacuum bag raw material is wound up by the winding assembly 3. The guide roller 6 near the winding assembly 3 cooperates with the guide roller 7, so that the vacuum bag between the guide roller 6 and the guide roller 7 is in a vertical state. By utilizing the hydrophobicity of the vacuum bag and the vertical angle, the vacuum bag pressure is reduced. The liquid adhering to the surface of the empty bag can be connected to the inlet and outlet pipes of the water tank 4. The inlet and outlet pipes can be opened or closed by using a solenoid valve, so that the liquid in the water tank 4 can be discharged through the outlet pipe. The inlet pipe is connected to a water source, so that liquid can be injected into the water tank 4. The injection of water source requires the use of a filtration device to filter the water quality and filter out solid impurities entrained in the liquid. Since the water tank 4 uses the inlet and outlet pipes and other water injection and drainage methods as existing technology, the specific form, usage and installation method of the inlet pipe and related structures will not be described in detail in this application.

[0020] Please see Figure 1 and Figure 3 The drying assembly 5 includes a fan 501 installed on one side of the device body 1. A ventilation main pipe 502 is installed on the inner wall of the device body 1. One end of the ventilation main pipe 502 is fixedly connected to two ventilation branch pipes 503. The ventilation branch pipes 503 are located between the guide roller 6 and the water tank 4. The two ventilation branch pipes 503 are fixedly connected to linearly arrayed air ducts on opposite sides. The other end of the ventilation main pipe 502 is fixedly connected to the exhaust end of the fan 501 by a connecting pipe 504.

[0021] Please see Figure 1 and Figure 3 The fan 501 is equipped with a dustproof housing 8 on the outside, and an air inlet 9 is opened on one side of the dustproof housing 8. A filter plate 10 with a linear array is installed inside the dustproof housing 8, and the filter plate 10 is located between the dustproof housing 8 and the air inlet 9. Specifically, the multiple filter plates 10 are coarse particle filter, fine particle filter and activated carbon filter, which are used to filter dust and impurities in the air and adsorb moisture, thereby purifying the air entering the fan 501. The fan 501 is electrically connected to the power supply. The models of the fan 501 and the servo motor 264 are not limited, and are mainly adapted to the equipment.

[0022] Please see Figure 2 The device body 1 has material inlets 11 at both ends, and guide rollers 12 are rotatably connected to the inner wall of the device body 1 at both material inlets 11.

[0023] Please see Figure 2 and Figure 4 Two bidirectional screws 13 are rotatably connected to the inner wall of the device body 1. Two symmetrically arranged correction plates 14 are threaded on the outer side of the bidirectional screws 13. A through guide opening is opened on one side of the correction plate 14. The guide roller 3 12 is located inside the guide opening. Three telescopic screw corrugated covers 15 are sleeved on the outer side of the bidirectional screws 13. The two ends of the three telescopic screw corrugated covers 15 are respectively fixedly connected between the two correction plates 14 and between the correction plates 14 and the inner wall of the device body 1. Specifically, the bidirectional screw 13 has two external threads arranged in a mirror symmetrical manner on its outer side. Two correction plates 14 are respectively threaded onto the two external threads in the bidirectional screw 13. By rotating the bidirectional screw 13, the bidirectional screw 13 drives the two correction plates 14 to move closer or further away from each other, thereby limiting the range of motion of the vacuum bag and keeping the vacuum bag conveying position centered. The telescopic screw corrugated cover 15 plays a role in protecting the bidirectional screw 13 and preventing dust.

[0024] Please see Figure 1 and Figure 5 The embossing assembly 2 includes a mounting plate 21 and a fixing plate 22 fixedly connected to one end of the device body 1. A movable plate 23 is slidably arranged between the mounting plate 21 and the fixing plate 22. A lifting component 24 for adjusting the lifting of the movable plate 23 is provided on the mounting plate 21. An embossing roller 25 is rotatably connected to the opposite side of the movable plate 23 and the fixing plate 22. A rotating component 26 for driving the embossing roller 25 to rotate is provided at one end of the device body 1.

Two guide rods 244 are fixedly provided on the upper part of the lifting component 24. A through-type rotating opening and two guide openings are opened on the mounting plate 21. The sleeve 242 is rotatably connected to the inside of the rotating opening. The guide rods 244 slide inside the guide openings. Specifically, by rotating the sleeve 242, the sleeve 242 uses the cooperation of the threaded rod 243 and the adjusting rod 241 to adjust the height of the top embossing roller 25, thereby adjusting the distance between the two embossing rollers 25 according to the different thicknesses of the vacuum bag.

[0026] Please see Figure 1 and Figure 5 The rotating component 26 includes a hexagonal rod 261 rotatably connected between the mounting plate 21 and the fixed plate 22. Two sliding tubes 262 are slidably sleeved on the outside of the hexagonal rod 261. Two fixing blocks are rotatably sleeved on the outside of the sliding tubes 262. The two sets of fixing blocks are respectively fixedly set at one end of the fixed plate 22 and the moving plate 23. The end of the embossing roller 25 and the end of the sliding tube 262 are both fixedly sleeved with bevel gears 263. The two bevel gears 263 are meshed with each other. A servo motor 264 is installed on one side of the device body 1. The output shaft of the servo motor 264 is fixedly connected to the bottom end of the hexagonal rod 261. Specifically, the servo motor 264 is electrically connected to the power supply. The servo motor 264 drives the hexagonal rod 261 to rotate, and the hexagonal rod 261 drives the two sliding tubes 262 to rotate together. The sliding tubes 262 drive the embossing roller 25 to rotate via the bevel gear 263. Dust covers are installed at one end of the fixed plate 22 and the moving plate 23. The dust covers cover the sliding tubes 262 and the bevel gear 263, thereby providing dust protection and protection for the drive structure. A circular hole needs to be opened at the corresponding position of the dust cover relative to the sliding tube 262. The end of the sliding tube 262 rotates inside the circular hole through a sealed bearing. An oil injection hole can also be provided on the dust cover to inject lubricating oil into the bevel gear 263. This dust prevention method and related structure are existing technologies and equipment. The specific form, usage and installation method are not described in detail in this application.

[0027] Working principle: The vacuum bag passes through the embossing assembly 2, then through the inside of the device body 1, and is finally wound up by the winding assembly 3. The vacuum bag passes in sequence around the upper part of the guide roller 3 12 near the embossing assembly 2, the upper part of the guide roller 1 6 near the embossing assembly 2, the bottom of the guide roller 2 7, passes between the two ventilation branch pipes 503, the upper part of the guide roller 1 6 near the winding assembly 3, and the upper part of the guide roller 3 12 near the winding assembly 3. Cooling water is added to pool 4 to cool the vacuum bag. Then, the fan 501 is started.
