Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of packaging bag processing equipment, specifically a device for coating pharmaceutical packaging bags with varnish. Background Technology
[0002] Packaging bags are bags used to package various goods, facilitating transportation and storage during production and distribution. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags end up in landfills like regular waste, with only 7% being recycled.
[0003] The prior art provides a pharmaceutical packaging bag coating equipment (publication number CN221869045U), including a support mechanism, a drying mechanism and a curing mechanism, and an oil storage tank at the bottom of the support mechanism; the support mechanism includes a frame, a connecting ring fixedly connected to the frame, and an elastic sheet inside the connecting ring; the drying mechanism includes a fan, a rotary joint at the output end of the fan, and a drying component rotatably connected to the fan through the rotary joint; an adjustment component is provided on the side of the drying component away from the rotary joint. The advantage of this invention is that, by incorporating a drying mechanism, this pharmaceutical packaging bag coating equipment can blow off excess varnish from the pharmaceutical packaging bag and dry the varnish on the bag. Then, during the curing mechanism, the varnish on the pharmaceutical packaging bag is cured, ensuring the effectiveness of the varnish coating and thus improving the quality of the processed pharmaceutical packaging bags.
[0004] Based on the above patent search, the patents mentioned above use a drying mechanism to blow off excess varnish from pharmaceutical packaging bags. When there is too much varnish on the packaging bags, relying solely on the drying mechanism to blow it off may result in uneven distribution of the varnish on the surface of the packaging bags. During the blowing process, the varnish in some areas may be excessively dispersed, while some areas may still have too much varnish remaining, thus affecting the overall drying effect and coating quality. At the same time, excess varnish may be blown into the air or other parts of the equipment during the blowing process, resulting in waste of varnish. This not only increases production costs but may also cause environmental pollution. Therefore, we need to propose a device for coating pharmaceutical packaging bags with varnish.

[0023] 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.
[0024] Please see Figure 1-5 This utility model provides a technical solution:
[0025] A device for coating varnish on pharmaceutical packaging bags includes a workbench 1, two sets of support plates 2 on the top of the workbench 1, a U-shaped frame 3 on the top of the two sets of support plates 2, a drying component 4 on the top of the U-shaped frame 3 for drying the varnish on the surface of the pharmaceutical packaging bags, and a scraping component 5 inside the U-shaped frame 3 for scraping off excess varnish on the surface of the pharmaceutical packaging bags.
[0026] The oil scraping assembly 5 includes a fixed frame 51 fixedly installed inside the C-shaped frame 3. Cylinders 52 are installed on both sides of the fixed frame 51. The telescopic ends of the two sets of cylinders 52 pass through the fixed frame 51 and are equipped with scrapers 53.
[0027] Feeding rollers 6 are rotatably installed on one side of the two sets of support plates 2 facing each other. An oiling box 7 is installed at the bottom of the workbench 1. A through groove 8 that works with the oiling box 7 is opened on the top of the workbench 1. A winding roller 9 is rotatably installed on one side of the two sets of support plates 2 facing each other.
[0028] By setting up the oiling roller, oiling trough 8, and take-up roller 9, and designing the automatic feeding and take-up roller 9, continuous and efficient oiling operations can be achieved. The feeding roller 6 is responsible for feeding the packaging bags of medicines to be oiled into the bottom of the oiling box 7, while the take-up roller 9 is responsible for rolling up the oiled items, thus forming a complete production process. This design can significantly improve production efficiency and reduce the tediousness and delays of manual operation.
[0029] The inside of the through groove 8 is equipped with two sets of fixing plates 10. The first guide roller 11 is rotatably installed on the opposite side of the two sets of fixing plates 10. The second guide roller 12 is rotatably installed on the opposite side of the two sets of support plates 2. The inside of the shaped frame 3 is rotatably equipped with a third guide roller 13.
[0030] By setting up the fixed plate 10, the first guide roller 11, the second guide roller 12 and the third guide roller 13, the rolling action of the guide rollers can reduce the friction between the material and the equipment, reduce the resistance of the material during the transmission process, thereby improving the stability of the transmission. It can also ensure that the raw materials of the packaging bag remain in close contact with the outer surface of the guide rollers during the transmission process, which helps to optimize the bonding effect of the material, reduce the generation of bubbles and wrinkles, and improve product quality.
[0031] Two sets of slide rods 14 are installed on one side of each of the two sets of scrapers 53, and multiple sets of slide rods 14 are slidably arranged inside the fixed frame 51.
[0032] The slide bar 14 provides stable support for the scraper 53. When the scraper 53 scrapes or moves, the slide bar 14 ensures that the scraper 53 does not deviate from the predetermined trajectory, thereby improving the stability of the scraper 53.
[0033] The drying assembly 4 includes a drying chamber 41 fixedly installed on the top of the U-shaped frame 3. A fan 42 is installed on the top of the U-shaped frame 3. The air inlet pipe of the fan 42 is connected to one side of the drying chamber 41. The air outlet pipe of the fan 42 is connected to two sets of conveying pipes 43. Two sets of air outlet hoods 44 are installed inside the U-shaped frame 3. The other ends of the two sets of conveying pipes 43 are respectively connected to one side of the two sets of air outlet hoods 44.
[0034] With the setting of the drying component 4, the fan 42 draws in the hot air in the drying chamber 41 and delivers it to the air outlet hood 44 through the conveying pipe 43. The two sets of air outlet hoods 44 are located on both sides of the medicine packaging bag. The hot air is sprayed out through the air outlet hole 15 on the air outlet hood 44 to evenly dry the varnish on both sides of the packaging bag, thereby improving the drying uniformity.
[0035] Multiple sets of air outlet holes 15 are opened on one side of the two sets of air outlet hoods 44 facing each other, and the multiple sets of air outlet holes 15 are arranged in a rectangular array.
[0036] By setting the air outlets 15, the rectangular array of air outlets 15 allows the hot air to be distributed more evenly within the air outlet hood 44. When the fan 42 blows hot air into the air outlet hood 44, the hot air will flow out through these evenly distributed air outlets 15, thereby avoiding local overheating or overcooling. This evenly distributed hot air helps to ensure temperature consistency during the drying process and improves air outlet uniformity.
[0037] The inside of the bracket 3 is equipped with two sets of lamp covers 16, and each set of lamp covers 16 is equipped with multiple sets of curing lamps 17.
[0038] With the lampshade 16 and curing lamps 17, multiple sets of curing lamps 17 are located on both sides of the medicine packaging bag. The curing lamps 17 will further cure the varnish on the surface of the medicine packaging bag, thereby effectively improving the coating effect.
[0039] Working Principle: In use, the medicine packaging bag is fed into the equipment via the feeding roller 6. Then, the medicine packaging bag passes through the second guide roller 12 and enters the oiling tank 7, where it is coated with varnish. After oiling, the medicine packaging bag continues to move forward via the first guide roller 11. Subsequently, the cylinder 52 is activated, and both sets of cylinders 52 simultaneously drive the scraper 53 to move inward, making the scraper 53 adhere to the surface of the medicine packaging bag. During the conveying process, the two sets of scrapers 53 can effectively scrape off excess material from both sides of the medicine packaging bag. After the varnish is removed and excess varnish is scraped off, the medicine packaging bag enters the drying assembly 4. The fan 42 draws in hot air from the drying chamber 41 and delivers it to the air outlet hood 44 through the conveying pipe 43. The hot air is sprayed out through the air outlet 15 on the air outlet hood 44 to dry the varnish on the surface of the medicine packaging bag. After drying, the medicine packaging bag passes through the curing lamp 17, which cures the varnish on the surface of the medicine packaging bag. After curing, the medicine packaging bag continues to move forward, passes through the third guide roller 13, and is finally wound up by the winding roller 9.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
