Abstract
Description
Technical Field
[0001] This invention mainly relates to the field of indoor electrical appliance technology, specifically to a paper sterilization bag and its production process. Background Technology
[0002] Sterilization bags are designed to prevent bacterial contamination of the items inside. They are typically completely sealed, preventing bacteria from entering and thus achieving their effect. However, existing sterilization bags still have shortcomings: while they achieve sealed preservation of items, the sterilization requirements are higher in the medical field. After sealing the medical products inside, the sterilization bags usually need to be heated for further sterilization. However, existing sterilization bags generally use a paper-plastic heat-bonding method, which can easily lead to the deterioration of the paper and plastic material when subjected to high-temperature sterilization.
[0003] During the specific implementation process, the inventors discovered the following defects: Existing sterilization packaging bags generally use a paper-plastic heat bonding molding method. When exposed to high-temperature sterilization, this type of paper-plastic sterilization packaging bag is prone to deterioration of the paper-plastic material, which in turn causes the medical supplies inside to deteriorate. Furthermore, during the final cutting step, if the paper-plastic sterilization packaging bag develops surface wrinkles that cause stacking, the stacked paper-plastic sterilization packaging bags will be cut together, resulting in a large area of the finished product being scrapped.

[0015] Furthermore, the telescopic slide rod and the cutting disc are elastically connected on the surface of the bridge frame via a telescopic spring above the suspension plate.
[0016] A manufacturing process for paper sterilization bags, characterized by the following steps:
[0017] Ⅰ. Kraft paper that has passed the raw material quality inspection is installed on the surface of the upper kraft paper roller and the lower kraft paper roller respectively. Kraft paper on the surface of the upper kraft paper roller enters the pressing and bonding mechanism through the guide roller, and kraft paper on the surface of the lower kraft paper roller enters the pressing and bonding mechanism through the glue spraying equipment.

[0020] IV. Conduct finished product inspection on medical kraft paper sterilization bags.
[0021] 3. Beneficial effects:
[0022] Compared with the prior art, the technical solution provided by this invention has the following advantages:
[0023] This invention is rationally designed. By activating the stepper motor in the discharge device, two abrasive rollers are driven to pull the kraft paper onto the surfaces of the upper and lower kraft paper rollers. Simultaneously, the pressure tank in the glue spraying equipment begins to pressurize, transporting the glue from the adhesive storage tank to the pressure tank via a metal corrugated pipe. The glue is then sprayed onto the kraft paper on the surface of the kraft paper rollers and the kraft paper passing through the passageway through glue nozzles located below the pressure tank.
[0024] Simultaneously, the kraft paper on the surface of the upper kraft paper roller and the kraft paper on the surface of the lower kraft paper roller passing through the groove enter the pressing and bonding mechanism. The hydraulic lifting device in the pressing and bonding mechanism drives the upper extrusion block to press and bond the upper and lower kraft paper. After the bonded kraft paper passes through the correction roller group, it enters another pressing and bonding mechanism for printing. This avoids the problem of paper-plastic sterilization packaging bags easily deteriorating when facing secondary high-temperature sterilization.
[0025] After the bonded kraft paper products pass through the discharge device and below the flexible slitting device, if the paper sterilization packaging bags are stacked due to surface wrinkles, the thicker paper sterilization packaging bags will pass through the cutting disc. Under the action of the extension spring at its upper end, the cutting disc will elastically move upward, avoiding the situation where a large number of finished products are scrapped due to direct cutting of the stacked paper sterilization packaging bags.

[0038] A paper sterilization bag and its manufacturing process, characterized in that the process includes the following steps:
[0039] Ⅰ. Kraft paper that has passed the raw material quality inspection is installed on the surface of the upper kraft paper roller and the lower kraft paper roller respectively. Kraft paper on the surface of the upper kraft paper roller enters the pressing and bonding mechanism through the guide roller, and kraft paper on the surface of the lower kraft paper roller enters the pressing and bonding mechanism through the glue spraying equipment.
[0040] II. The upper and lower kraft paper are pressed and bonded by a pressing and bonding mechanism, and water-based ink is printed by a second pressing and bonding mechanism;
[0041] Ⅲ. The kraft paper after bonding and printing is cut using a flexible slitting device;
[0042] IV. Conduct finished product inspection on medical kraft paper sterilization bags.
[0043] Combination Figure 1-5 An example of a paper sterilization bag production equipment is described below;
[0044] The production equipment for the paper sterilization bag includes a long base 1, a raw material side frame 2 on one side of the long base 1, an upper kraft paper roller 3 at the top of the raw material side frame 2, a lower kraft paper roller 4 at the lower end of the upper kraft paper roller 3 on the surface of the raw material side frame 2, a glue spraying device 5 on the top surface of the long base 1, a guide roller 6 on one side of the glue spraying device 5 on the upper surface of the long base 1, a pressing and bonding mechanism 7 on one side of the guide roller 6 on the upper surface of the long base 1, a discharge device 8 on the other side of the pressing and bonding mechanism 7 on the upper surface of the long base 1, and a flexible slitting device 9 on the upper surface of the discharge device 8. This invention sprays glue onto the surfaces of the upper kraft paper roller 3 and the lower kraft paper roller 4, and then uses the pressing and bonding mechanism 7 to bond and print the two pieces of kraft paper. Finally, the flexible slitting device 9 cuts the finished product, thus realizing the structure of the paper sterilization bag and avoiding the problem of the paper-plastic deterioration during high-temperature sterilization, which could lead to the deterioration of the medical supplies inside.
[0045] The adhesive spraying device 5 includes an adjustable frame 501. An adhesive storage tank 502 is installed on one side of the adjustable frame 501 via a pipe. A sliding groove 503 is provided on the upper surface of the adjustable frame 501. A passageway 504 for passing kraft paper is provided on the surface of the adjustable frame 501. An adjusting rod 505 is movably connected to the surface of the sliding groove 503. A pressure tank 506 is provided on the lower surface of the adjusting rod 505.

Several adjusting rods 505, pressure tanks 506, and adhesive nozzles 507 are provided on the surface of the sliding groove 503. The pressure tanks 506 are interconnected via the metal corrugated pipes 508. The top of the adjusting rod 505... The end is a nut structure, which is clamped and connected to the surface of the sliding groove 503 at the upper end of the adjustable frame 501 by the pressure tank 506 below. The adhesive storage tank 502 is sealed to the pressure tank 506 through the metal bellows 508. The discharge device 8 includes a protective shell 801. A stepper motor 802 is provided on one side of the protective shell 801. A sanding roller 803 is provided inside the protective shell 801 on one side of the stepper motor 802. A metal anti-cutting block 804 is provided on one side surface of the sanding roller 803 above the long strip base 1. An operating plate 805 is provided on the lower surface of the metal anti-cutting block 804. The sanding roller 803 and the stepper motor 802 form a transmission structure. There are two sanding rollers 803 in the protective shell 801, and they form a transmission structure through a transmission belt.
[0046] In this embodiment, the stepper motor 802 in the discharge device 8 drives the two abrasive rollers 803 to pull the kraft paper, causing the kraft paper on the surface of the upper kraft paper roller 3 and the lower kraft paper roller 4 to move. At this time, the pressure tank 506 in the glue spraying device 5 starts to pressurize, and the glue in the glue storage tank 502 is transported to the inside of the pressure tank 506 through the metal corrugated pipe 508. The glue spray nozzle 507 below the pressure tank 506 sprays glue onto the kraft paper on the surface of the lower kraft paper roller 4 and the surface of the passage groove 504.
[0047] The pressing and bonding mechanism 7 includes fixed support blocks 701 disposed on both sides of the top surface of the elongated base 1. A hydraulic lifting device 702 is disposed on the upper surface of the fixed support block 701. An upper pressing block 703 is disposed on the lower surface of the hydraulic lifting device 702. A correction roller group 704 is disposed on one side of the hydraulic lifting device 702. A lower support block 705 is disposed below the upper pressing block 703 at the top of the elongated base 1. Two hydraulic lifting devices 702 and two upper pressing blocks 703 are disposed on the other side of the correction roller group 704. The upper pressing block 703 forms a lifting structure under the action of the hydraulic lifting device 702.
[0048] In this embodiment, the kraft paper on the surface of the upper kraft paper roller 3 and the kraft paper on the surface of the lower kraft paper roller 4 passing through the groove 504 simultaneously enter the pressing and bonding mechanism 7. The hydraulic lifting device 702 in the pressing and bonding mechanism 7 drives the upper extrusion block 703 to press and bond the upper and lower kraft paper. After the bonded kraft paper passes through the correction roller group 704, it enters another pressing and bonding mechanism 7 for printing. This avoids the problem that the paper-plastic sterilization packaging bag is prone to deterioration when facing secondary high-temperature sterilization.
[0049] The flexible slitting device 9 includes a bridge frame 901. An adjusting screw 902 is movably connected to the upper surface of the bridge frame 901. A telescopic slide rod 903 is slidably connected to the upper surface of the bridge frame 901. A crossbar 904 is fixedly connected to the lower surface of the telescopic slide rod 903.

A telescopic spring 907 is provided on the upper surface of the suspension plate 906. The telescopic slide rod 903 and the cutting disc 905 are elastically connected on the surface of the bridge frame 901 through the telescopic spring 907 above the suspension plate 906.
[0050] In this embodiment, the bonded kraft paper finished product passes under the flexible slitting device 9 through the discharge device 8. At this time, if the paper sterilization packaging bags are stacked due to surface wrinkles, the thicker paper sterilization packaging bags pass through the cutting disc 905. Under the action of the extension spring 907 at its upper end, the cutting disc 905 will elastically move upward, avoiding the situation where a large number of finished products are scrapped due to direct cutting of the stacked paper sterilization packaging bags.

However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
