This invention relates to the field of packaging processing technology, specifically to a dialysis paper pasting and printing apparatus. A roll-type conveyor assembly transports semi-finished packaging bags or sterilization bags to the bonding worktable. During this process, a dust removal mechanism cleans and sterilizes the surfaces of the packaging bags and sterilization bags. For dialysis paper feeding, a paper feeding assembly automatically feeds each sheet of dialysis paper, and the adhesive coating module of the bonding assembly applies adhesive to the dialysis paper, creating a dust-free and sterile production environment. The paper feeding assembly transfers each sheet of dialysis paper to the corresponding bonding area of ​​the packaging bag or sterilization bag. A pressing mechanism initially presses the dialysis paper and packaging bag together to prevent the dialysis paper from falling off. After the initial bonding, a wrinkle-removing mechanism further presses the dialysis paper and packaging bag together and smooths them, preventing tears or poor sealing at the bonding point, while also ensuring the flatness of the printing surface of the dialysis paper.

Technical Field

[0001] This invention relates to the field of packaging processing technology, specifically to a dialysis paper pasting and printing apparatus. Background Technology

[0002] With increasing emphasis on the medical service industry, the development prospects of medical device sterilization packaging are encouraging, and the selection of packaging materials has become a key focus. Dialysis paper, as an important material for medical device sterilization packaging, is typically coated, printed (inked), and bagged to form paper-plastic bags. Because dialysis paper is convenient to use, can be stored for a long time, and its specifications can be customized according to the specific device size, it is highly practical and favored by the industry and manufacturers.

[0003] Compared to porous materials like non-woven fabrics, medical dialysis paper is cheaper and easier to use. It can be heat-sealed or glued with PE, PP, and other film materials, and is commonly used as a sterilization packaging material for medical devices in the medical packaging industry. Currently, the main sterilization methods for packaging materials in China are ETO (ethylene oxide) sterilization and high-temperature moist heat steam sterilization. Therefore, medical dialysis paper needs to have a certain degree of air permeability and a small pore size to prevent bacteria and dust from entering while allowing ethylene oxide gas or vapor to pass through, thus achieving the purpose of sterilizing the packaged medical devices and items. In practical industrial applications, dialysis paper is generally used in higher-end medical device sterilization packaging or blister packaging as a rigid blister sealing cap material, similar to PETG, PVC, PS, PP, and PET blister boxes, and the sealing effect is good.

[0004] Therefore, in the production and processing of some medical sterilization packaging and sterilization bags, it is necessary to bond dialysis paper to membrane materials and print relevant medical instruction graphics on the surface of dialysis paper. Thus, the present invention provides a device for bonding and printing dialysis paper on medical sterilization packaging. Summary of the Invention

[0044] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0045] like Figures 1 to 15 As shown, the following preferred technical solutions are provided:

[0046] A dialysis paper pasting and printing device includes: a bag roll conveying assembly 1 for feeding medical packaging bags or sterile bags, a paper feeding assembly 2 for feeding dialysis papers one sheet at a time, an adhesive assembly 3 for pasting dialysis papers onto corresponding medical packaging bags or sterile bags, and a printing assembly 4 for printing relevant advertising information on the surface of the dialysis papers. The bag roll conveying assembly 1, the paper feeding assembly 2, the adhesive assembly 3, and the printing assembly 4 are all mounted on a frame 6. The discharge end of the bag roll conveying assembly 1 is directly opposite the paper feeding assembly 2 and the adhesive assembly 3. A lifting worktable 5 is provided directly below the discharge end of the paper feeding assembly 2, and a lifting worktable 5 is also installed directly below the printing assembly 4. The two worktables 5 are horizontally aligned.

[0047] The bag material roll conveying assembly 1 includes a roll conveyor unit 1a for winding and unwinding bag material and a bag material dust removal mechanism 1c. The feed roller assembly 1a1 of the roll conveyor unit 1a is mounted on the frame 6 via a roller frame 1a2. A feed clamping assembly 1b for assisting in intermittently clamping the bag material is also mounted on the roller frame 1a2. The bag material dust removal mechanism 1c is mounted on one side of the roller frame 1a2 via a dust removal frame 1c1 and is located between the feed clamping assembly 1b and the pasting worktable 5. The bag material dust removal mechanism 1c includes... The system includes a dust-adhesive paper roller 1c6 for adhering dust to the bonding surface of medical packaging bags or sterilized bags and dialysis paper, and a disinfection roller 1c7 for disinfection. Both the dust-adhesive paper roller 1c6 and the disinfection roller 1c7 are mounted on a dust removal frame 1c1. The printing assembly 4 includes a wrinkle-removing mechanism 4a for smoothing and removing wrinkles from the newly bonded dialysis paper and packaging bag, and a printing module 4b for printing on the outer surface of the dialysis paper. The wrinkle-removing mechanism 4a uses two sets of adjustable wrinkle-removing rollers 4a9 to remove wrinkles from the passing bag material and dialysis paper.

[0048] Specifically, to address the technical challenges of bonding the required dialysis paper and printing relevant information on the paper during the production of medical packaging bags or sterilization bags, this invention utilizes a bag roll conveying assembly 1 to roll-feed the semi-finished packaging bags or sterilization bags to the bonding worktable 5. During this process, a bag dust removal mechanism 1c removes dust and sterilizes the surfaces of the packaging bags and sterilization bags, preventing dust and other contaminants from being trapped inside the bag during dialysis paper bonding. For feeding the dialysis paper, a paper feeding assembly 2 automatically feeds each sheet of dialysis paper, and the adhesive coating module 3a of the bonding assembly 3 applies the adhesive to the dialysis paper. Applying adhesive avoids the influence of dust and bacteria from manual material feeding, creating a dust-free and sterile production environment. The paper feeding component 2 transfers the dialysis paper sheet by sheet to the bonding area of ​​the corresponding packaging bag or sterilization bag. The pressing mechanism 3c initially presses the dialysis paper and packaging bag together to prevent the dialysis paper from falling off. After the dialysis paper and packaging bag are initially bonded, the wrinkle removal mechanism 4a further presses the dialysis paper and packaging bag together and smooths them out to remove wrinkles and prevent wrinkles at the bonding area from causing tears or poor sealing. It also ensures the flatness of the dialysis paper surface to be printed, preventing unclear printing.

[0049] The following preferred technical solutions are provided:

[0050] The bag dust collection mechanism 1c also includes a feeding roller assembly 1c2 and a guide roller 1c4. The feeding roller assembly 1c2 is rotatably mounted on the dust collection frame 1c1, and the bag material can pass through the feeding roller assembly 1c2. The guide roller 1c4 is mounted on the dust collection frame 1c1 via a swing arm frame 1c3. The dust-adhesive paper roller 1c6 and the disinfection roller 1c7 are both rotatably mounted on the swing arm frame 1c3 via a movable bracket 1c9. A sea-mounted... The cotton roller 1c5 and the sponge roller 1c5 are movably mounted on the swing arm frame 1c3 via the pneumatic push rod 1c10. The pneumatic push rod 1c10 is mounted on both sides of the swing arm frame 1c3. The disinfection roller 1c7 is mounted at the end of the swing arm frame 1c3. The dust-adhesive paper roller 1c6 is mounted at the end of the swing arm frame 1c3 via the adjusting seat 1c12 and is located above the disinfection roller 1c7. The heating roller 1c8 is also mounted below the swing arm frame 1c3. An electric heating ring 1c11 is sleeved on the heating roller 1c8.

[0051] Specifically, to solve the technical problem of dust removal during the conveying process of packaging bag materials, this invention involves passing the bag material through the feed roller group 1a1 and the feed clamping assembly 1b of the self-winding conveyor unit 1a, pulling it through the feed roller group 1c2, and then sequentially passing above the guide rubber roller 1c4, below the sponge roller 1c5 and below the disinfection roller 1c7, and winding it around to the heating roller 1c8. The friction between the bag material and each roller achieves dust removal, disinfection, and heating of the bag material. Alcohol is introduced into the sponge roller 1c5, and the disinfection roller 1c7 is set to ultraviolet disinfection mode to remove dust and disinfect the surface of the bag material. The pneumatic push rod 1c10 controls and adjusts the tightness between the sponge roller 1c5 and the bag material so that the sponge roller 1c5 can wipe the surface of the bag material. The dust-adhesive paper roller 1c6 adheres dust to the surfaces of the sponge roller 1c5 and the disinfection roller 1c7 to prevent dust from accumulating on the surfaces of the sponge roller 1c5 and the disinfection roller 1c7. The distance between the dust-adhesive paper roller 1c6, the disinfection roller 1c7 and the sponge roller 1c5 is adjusted by the adjusting seat 1c12. When the bag material after disinfection and dust removal passes through the heating roller 1c8, the electric heating ring 1c11 on the heating roller 1c8 preheats and dries the bag material. Finally, the bag material is conveyed to the bonding worktable 5.

[0052] The following preferred technical solutions are provided:

[0053] The paper feeding assembly 2 includes a feeding conveyor belt 2a for feeding dialysis paper and a slitting mechanism 2b for slitting the fed dialysis paper. The feeding conveyor belt 2a is mounted on the frame 6 via a conveyor frame 2a2. The slitting mechanism 2b is mounted above the discharge end of the feeding conveyor belt 2a. The discharge end of the feeding conveyor belt 2a is also equipped with a turning and transferring mechanism 2c for turning and transferring the dialysis paper. A paper separating bin 2a1, flush with the feeding conveyor belt 2a, is provided between the discharge end of the feeding conveyor belt 2a and the turning and transferring mechanism 2c. After the slitting paper enters the paper separating bin 2a1, the adhesive assembly 3 applies adhesive to the edges of the paper, and the turning and transferring mechanism 2c transfers the adhesive-coated paper to the worktable 5 at the adhesive bonding point.

[0054] Specifically, in order to solve the technical problem of feeding and conveying dialysis paper, the present invention uses a feeding conveyor belt 2a to gradually transfer the dialysis paper to the bonding assembly 3. During this process, the paper on the feeding conveyor belt 2a is separated by a splitting mechanism 2b to prevent the paper from stacking. Multiple sheets of dialysis paper enter the paper separating bin 2a1 at the same time. The paper entering the paper separating bin 2a1 is turned and picked up by a turning and transferring mechanism 2c and transferred to the worktable 5 at the bonding assembly 3.

[0055] The paper-feeding mechanism 2b includes a guide frame 2b1, a mounting frame 2b2, an adjusting rod 2b3, and a paper-feeding wheel 2b4.

The paper-feeding wheel 2b4 is driven to rotate by the first drive module 2b5, which is installed on the upper end of the fixing plate 2b6.

[0056] Specifically, in order to solve the technical problem of paper stacking and jamming during the feeding and conveying process of dialysis paper, the present invention uses a slitting mechanism 2b to slit the dialysis paper on the feeding conveyor belt 2a. The first drive module 2b5 drives the slitting wheel to rotate. The slitting wheel rotates in the opposite direction to the feeding conveyor belt 2a, and the paper on the surface of the feeding conveyor belt 2a is slitted and conveyed to the paper separation bin 2a1 one by one. The position and height of the slitting wheel are adjusted by the guide frame 2b1 and the adjusting rod 2b3.

[0057] The steering and transferring mechanism 2c includes a transfer frame 2c1, an electric push rod 2c2, and a first suction cup assembly 2c3. The transfer frame 2c1 is slidably installed at the discharge end of the feeding conveyor belt 2a. One end of the electric push rod 2c2 is fixedly installed on one side of the feeding conveyor belt 2a. The output end of the electric push rod 2c2 is fixedly connected to the lower end of the transfer frame 2c1. The first suction cup assembly 2c3 is installed below the transfer frame 2c1 through a lifting cylinder 2c4 and a rotating cylinder 2c5. The lifting cylinder 2c4 is vertically installed in the middle of the transfer frame 2c1. The rotating cylinder 2c5 is fixedly installed on the output end of the lifting cylinder 2c4. The first suction cup assembly 2c3 is fixedly installed on the output end of the rotating cylinder 2c5.

[0058] Specifically, in order to solve the technical problem of transferring the dialysis paper to be bonded, the present invention uses the first suction cup group 2c3 to pick up the dialysis paper in the paper distribution compartment 2a1. At this time, the lifting cylinder 2c4 and the rotating cylinder 2c5 control the lifting and rotating of the first suction cup group 2c3 so that the first suction cup group 2c3 can pick up the dialysis paper and complete the turning of the dialysis paper. After the picking is completed, the electric push rod 2c2 pushes the transfer frame 2c1 to move to the bonding component 3 to transfer the dialysis paper.

[0059] The following preferred technical solutions are provided:

[0060] The adhesive module 3a of the adhesive assembly 3 is installed on the upper end of the transfer frame 2c1. The adhesive module 3a can automatically apply adhesive to the four edges of the dialysis paper in the paper separation compartment 2a1. A flipping mechanism 3b and a pressing mechanism 3c are installed below the end of the conveyor frame 2a2 away from the feeding conveyor belt 2a. The flipping mechanism 3b includes a second drive module 3b1 and a second suction cup group 3b3. The second drive module 3b1 is fixedly installed at the end of the conveyor frame 2a2 away from the feeding conveyor belt 2a. The second suction cup group 3b3 is connected to the second drive module 3b1 through a flipping shaft 3b4 and a telescopic rod group 3b2.

The lower end of the telescopic rod group 3b2 is fixedly connected to the second suction cup group 3b3.

[0061] Specifically, to solve the technical problems of applying glue to dialysis paper and transferring and flipping the glued dialysis paper, this invention uses a glue-applying module 3a to automatically apply glue to the four sides of the dialysis paper in the paper distribution compartment 2a1. Then, the first suction cup group 2c3 picks up the glued dialysis paper and moves it to the position of the second suction cup group 3b3. Then, the second drive module 3b1 drives the flipping shaft 3b4 and the telescopic rod group 3b2 to rotate 180°, turning the second suction cup group 3b3 to the top, directly below the first suction cup group 2c3 and the dialysis paper, and picking up the un-glue side of the dialysis paper. After that, the second drive module 3b1 rotates 180°, turning the second suction cup group 3b3 and the dialysis paper to the bottom, directly above the bonding area of ​​the bag material. The telescopic rod group 3b2 gradually sticks the second suction cup group 3b3 and the dialysis paper onto the bag material, completing the initial bonding.

[0062] The pressing mechanism 3c includes a pressing plate 3c1 and a pull rod 3c3. The pressing plate 3c1 is rotatably mounted on the lower end of the conveyor frame 2a2 and faces the worktable 5 at the bonding point via a rotating rod 3c2. One end of the pull rod 3c3 is fixedly connected to the flipping shaft 3b4, and the other end is connected to both sides of the pressing plate 3c1 via a movable hinge rod 3c4. The movable hinge rod 3c4 is inserted into the pull rod 3c3, and the movable hinge rod 3c4 and the pull rod 3c3 are connected by a spring 3c5.

[0063] When the second suction cup group 3b3 is rotated upward, the pull rod 3c3 drives the movable hinge rod 3c4 to pull the pressing plate 3c1 and rotate it to the horizontal, so that it further presses the bag material and dialysis paper on the worktable 5 below; when the second suction cup group 3b3 is rotated downward, the pull rod 3c3 drives the movable hinge rod 3c4 to lift the pressing plate 3c1 and reset it.

[0064] Specifically, in order to solve the technical problem of adhesion between dialysis paper and bag material, the present invention uses a flipping mechanism 3b to drive a pressing mechanism 3c to press the dialysis paper adhered to the surface of the bag material. A porous structure is opened on the lower surface of the pressing plate 3c1 and air is supplied to the pressing plate 3c1. When the pressing plate 3c1 presses the dialysis paper and the bag material together, the drying of the adhesive on the dialysis paper is accelerated.

The spiral hanging strips on the two wrinkle-removing cylinders 4a10 rotate in opposite directions, and the spiral hanging strips on the upper and lower wrinkle-removing rollers 4a9 also rotate in opposite directions.

[0067] Specifically, to solve the technical problem of ensuring smooth printing by removing wrinkles from the pressed dialysis paper and bag material, this invention uses two wrinkle-removing rollers 4a9 rotating in opposite directions. The lifting module 4a2 and the lifting rail 4a3 support the two wrinkle-removing rollers 4a9 to move up and down. The adjusting screw module 4a7 drives the abutment wheel group 4a6 to move, thereby pushing the corresponding wedge block 4a5. This allows the lifting module 4a2 and the rail seat 4a4 to slide along the lifting rail 4a3, so as to adjust the distance between the screw wrinkle-removing rollers 4a9. This achieves the pressing of the dialysis paper and bag material as they pass between the two wrinkle-removing rollers 4a9. When the wrinkle-removing rollers 4a9 rotate, the wrinkle-removing cylinders 4a10 on the two counter-rotating wrinkle-removing rollers 4a9 smooth out the dialysis paper and bag material that are not yet fully bonded, preventing the wrinkles from affecting the printing.

[0068] like Figures 1 to 15 As shown, the following implementation steps are provided:

[0069] Step 1: The semi-finished packaging bags or sterilization bags are conveyed to the bonding worktable 5 by the bag material roll conveyor assembly 1. During this process, the surface of the packaging bags and sterilization bags is cleaned and sterilized by the bag material dust removal mechanism 1c. The dialysis paper is gradually transferred to the bonding assembly 3 by the feeding conveyor belt 2a. During this process, the paper on the feeding conveyor belt 2a is separated by the splitting mechanism 2b to prevent the paper from stacking. Multiple sheets of dialysis paper enter the paper separation bin 2a1 at the same time. The paper entering the paper separation bin 2a1 is turned and picked up by the turning and transferring mechanism 2c and transferred to the worktable 5 of the bonding assembly 3.

[0070] Step Two: The bag material to be conveyed is passed through the feed roller group 1a1 and the feed clamping assembly 1b of the self-winding conveyor unit 1a, and pulled through between the feed roller group 1c2. Then, it passes sequentially above the guide roller 1c4, below the sponge roller 1c5 and below the disinfection roller 1c7, and wraps around the heating roller 1c8. The friction between the bag material and each roller achieves dust removal, disinfection, and heating of the bag material. Alcohol is introduced into the sponge roller 1c5, and the disinfection roller 1c7 is set to ultraviolet disinfection mode to remove dust and disinfect the surface of the bag material. The tightness between the sponge roller 1c5 and the bag material is controlled and adjusted by the pneumatic push rod 1c10 to facilitate... The cotton roller 1c5 wipes the surface of the bag material, and the dust-adhesive paper roller 1c6 adheres dust to the surfaces of the sponge roller 1c5 and the disinfection roller 1c7 to prevent dust from accumulating on their surfaces. The distance between the dust-adhesive paper roller 1c6, the disinfection roller 1c7, and the sponge roller 1c5 is adjusted by the adjusting seat 1c12. After disinfection and dust removal, the bag material passes through the heating roller 1c8, where the electric heating ring 1c11 preheats and dries it. Finally, the bag material is conveyed to the bonding worktable 5. At the same time, the material pulling clamping assembly 7 on one side assists in clamping the bag material and pulling it to the position of the worktable 5.

[0071] Step 3: The dialysis paper on the feeding conveyor belt 2a is separated by the slitting mechanism 2b. The first drive module 2b5 drives the slitting wheel to rotate. The slitting wheel rotates in the opposite direction to the feeding conveyor belt 2a. The paper on the surface of the feeding conveyor belt 2a is slitted and transported to the paper separation bin 2a1 one by one. The position and height of the slitting wheel are adjusted by the guide frame 2b1 and the adjusting rod 2b3.

[0072] Step 4: The first suction cup assembly 2c3 picks up the dialysis paper from the paper separating compartment 2a1. At this time, the lifting cylinder 2c4 and the rotating cylinder 2c5 control the lifting and rotating of the first suction cup assembly 2c3 so that the first suction cup assembly 2c3 can pick up the dialysis paper and complete the turning of the dialysis paper. After the dialysis paper is picked up, the electric push rod 2c2 pushes the transfer frame 2c1 to the bonding assembly 3 to transfer the dialysis paper.

[0073] Step 5: The gluing module 3a automatically applies glue to the four sides of the dialysis paper in the paper separation compartment 2a1. Then, the first suction cup group 2c3 picks up the glued dialysis paper and moves it to the position of the second suction cup group 3b3. Then, the second drive module 3b1 drives the flipping shaft 3b4 and the telescopic rod group 3b2 to rotate 180°, turning the second suction cup group 3b3 to the top, directly below the first suction cup group 2c3 and the dialysis paper, and picking up the un-glue side of the dialysis paper. After that, the second drive module 3b1 rotates 180°, turning the second suction cup group 3b3 and the dialysis paper to the bottom, directly above the bag material bonding area. The telescopic rod group 3b2 gradually sticks the second suction cup group 3b3 and the dialysis paper to the bag material, completing the initial bonding.

[0074] Step 6: The flipping mechanism 3b drives the pressing mechanism 3c to press the dialysis paper adhering to the surface of the bag material. The lower surface of the pressing plate 3c1 is made of porous structure and air is supplied to the pressing plate 3c1. When the pressing plate 3c1 presses the dialysis paper and the bag material together, the drying of the dialysis paper adhesive is accelerated.

[0075] Step 7: By rotating two wrinkle-removing rollers 4a9 with opposite rotation directions, the lifting module 4a2 and lifting rail 4a3 support the two wrinkle-removing rollers 4a9 to move up and down. The adjusting screw module 4a7 drives the abutment wheel group 4a6 to move, thereby pushing the corresponding wedge block 4a5, so that the lifting module 4a2 and the rail seat 4a4 slide along the lifting rail 4a3, so as to adjust the distance between the screw wrinkle-removing rollers 4a9, so as to achieve the pressing of the dialysis paper and bag material when passing between the two wrinkle-removing rollers 4a9. When the wrinkle-removing rollers 4a9 rotate, the wrinkle-removing cylinders 4a10 on the two wrinkle-removing rollers 4a9 rotating in opposite directions smooth out the dialysis paper and bag material that are not completely glued, so as to prevent the pressed wrinkles from affecting the printing.

[0076] Step 8: Print relevant information advertisements on the dialysis paper after wrinkle removal using printing module 4b.
