Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to a device for attaching a film to the inside of dialysis paper. Background Technology

[0002] Dialysis paper is a special type of paper primarily used for separating and analyzing small molecules in biological samples. The pore size of the paper can be controlled to allow small molecules to pass through while blocking larger molecules. When used for packaging some medical supplies, it can sterilize the products while being waterproof and moisture-proof.

[0003] When existing packaging bags are used to package a syringe product with protrusions, the protrusions will rub against the dialysis paper, causing wear and tear on the product and generating paper scraps. Therefore, it is necessary to paste a transparent film on the inside of the dialysis paper corresponding to the protrusions to reduce friction. Currently, the commonly used method of pasting the film is manual pasting.

[0004] However, manual pasting is slow, inefficient, and it is difficult to ensure that the pasting position is accurately aligned with the protruding part of the syringe, which can easily lead to misalignment and cause the transparent film to fail.

[0005] Based on this, the present invention designs a dialysis paper inner film bonding device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a device for attaching a film to the inside of dialysis paper.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dialysis paper inner film application device includes a frame, a transparent film application device, and a packaging box conveying device;

[0009] The frame is equipped with a transparent film bonding device for bonding a transparent film to the inside of the dialysis paper and a packaging box conveying device for conveying the packaging box.

[0010] The transparent film bonding device includes a dialysis paper conveying assembly for conveying dialysis paper, a bonding drive assembly for providing bonding driving force, and a bonding assembly for intermittently driving the dialysis paper to bond with the transparent film. The dialysis paper conveying assembly, the bonding drive assembly, and the bonding assembly are connected to a frame, and the bonding drive assembly and the bonding assembly are connected to each other.

[0011] Furthermore, the frame includes a support, two platforms, and a mounting plate.

One end of the air extraction pipe passes through the mounting plate and extends to the inner side of the rotating cylinder from the synchronous wheel on the left side of the second synchronous wheel assembly. The other end of the air extraction pipe is connected to an air extraction device. The air extraction pipe is fixedly connected to the mounting plate and rotatably connected to the synchronous wheel and the rotating cylinder on the left side of the second synchronous wheel assembly. The front end of the air extraction pipe is fixedly connected to the air-blocking block, which is located inside the rotating cylinder and slidably connected to it. The air-absorbing plates are evenly arranged and fixedly installed on the outside of the rotating cylinder. Multiple through holes for adsorbing transparent films are opened on the air-absorbing plates.

[0015] Furthermore, when the long shaft end of the cam rotates to the left, the cam approaches the rotating drum, and the long shaft end of the cam and the rotating drum form a gap that can only accommodate the transparent film and dialysis paper.

[0033] In some embodiments, please refer to the accompanying drawings. Figures 1-8 A dialysis paper inner film application device includes a frame 1, a transparent film application device 2, and a packaging box conveying device 3;

[0034] The frame 1 is equipped with a transparent film bonding device 2 for bonding a transparent film to the inside of the dialysis paper and a packaging box conveying device 3 for conveying the packaging box.

[0035] The transparent film bonding device 2 includes a dialysis paper conveying assembly 21 for conveying dialysis paper, a bonding driving assembly 22 for providing bonding driving force, and a bonding assembly 23 for intermittently driving the dialysis paper to bond with the transparent film.

The single bonding drive assembly 22 also ensures the synchronicity of the lifting and the transparent film conveying, ensuring bonding accuracy.

[0037] The frame 1 includes a bracket 11, two platforms 12 and a mounting plate 13.

The cam 232 is sleeved on the outside of the rotating shaft 231 and fixedly connected to the rotating shaft 231. The rotating cylinder 234 is fixedly installed on the front end of the synchronous pulley to the left of the second synchronous pulley assembly 222. The inner side of the rotating cylinder 234 is hollow. One end of the air extraction pipe 233 passes through the mounting plate 13 and the front end of the synchronous pulley to the left of the second synchronous pulley assembly 222. The step wheel extends to the inside of the rotating drum 234. The other end of the suction pipe 233 is connected to the suction device. The suction pipe 233 is fixedly connected to the mounting plate 13. The suction pipe 233 is rotatably connected to the synchronous wheel on the left side of the second synchronous wheel component 222 and the rotating drum 234. The front end of the suction pipe 233 is fixedly connected to the air blocking block 235. The air blocking block 235 is located inside the rotating drum 234 and is in close contact with the rotating drum 234. The suction plate 236 is evenly arranged and fixedly installed on the outside of the rotating drum 234. The suction plate 236 has multiple through holes for adsorbing transparent film.

[0041] When the long shaft end of the cam 232 rotates to the left, the cam 232 approaches the rotating drum 234. The long shaft end of the cam 232 and the rotating drum 234 form a gap that can only accommodate the transparent film and dialysis paper. The air blocking block 235 is a cylindrical block with a fan-shaped cross-section. The air blocking block 235 blocks the air suction plate 236 located to the right and below the rotating drum 234.

The transparent film feeding device feeds the transparent film with the non-adhesive side facing the rotating drum 234 in sequence.

[0042] The bonding assembly 23 also includes two bonding rollers 237, which are rotatably mounted on the front end of the mounting plate 13. The two bonding rollers 237 are located below the rotating drum 234 and the cam 232, and a gap is formed between the two bonding rollers 237 that can only accommodate the transparent film and the dialysis paper.

[0043] The packaging box conveying device 3 includes a sprocket conveyor 31 and multiple mounting frames 32. The sprocket conveyor 31 consists of two chain sprocket structures, two fixed plates, two rotating shafts, and a drive motor. The sprockets of the two chain sprocket structures are rotatably mounted inside the two fixed plates. The two rotating shafts are fixedly mounted between the sprockets of the two chain sprocket structures. The output end of the drive motor is fixedly connected to one sprocket. The two fixed plates are fixedly mounted inside the two platforms 12. Multiple mounting frames 32 are evenly distributed and fixedly mounted between the chains of the two chain sprocket structures. Multiple packaging boxes 33 are placed inside the mounting frames 32. The mounting frames 32 have through holes for placing the packaging boxes 33. The packaging boxes 33 are used to place products, and the products are syringes with a protrusion on one side.

[0044] When the dialysis paper inner film application device is in normal use, the dialysis paper passes from the upper conveyor roller 213 through the space between the rotating drum 234 and the cam 232, and is then pulled from the lower end of the auxiliary roller 214 to the lower end of the lower conveyor roller 213. The first motor 211 and the second motor 221 are started. The first motor 211 drives one synchronous pulley of the first synchronous pulley component 212 to rotate. The belt of the first synchronous pulley component 212 causes both synchronous pulleys to rotate synchronously. The two synchronous pulleys of the first synchronous pulley component 212 drive the two conveyor rollers 213 to rotate synchronously. The auxiliary roller 214 assists in the turning and conveying of the dialysis paper. The second motor 221 drives one synchronous pulley of the second synchronous pulley component 222 to rotate. The two synchronous pulleys of the second synchronous pulley component 222 simultaneously drive the rotating shaft 231 and the rotating drum 234 to rotate. The rotating shaft 231 drives the cam 232 to rotate, activating the air extraction device. The air extraction device draws air from the inside of the rotating drum 234 through the air extraction pipe 233 to create a negative pressure, thus applying the non-adhesive side of the transparent film. As the air suction plate 236 rotates, the rotating drum 234 moves the transparent film to the right. Simultaneously, the long shaft end of the cam 232 moves to the left, causing the dialysis paper to move to the left and adhere to the adhesive side of the transparent film. At this point, the air blocking block 235 blocks the right air suction plate 236, causing the transparent film to detach from the rotating drum 234 and be pulled downwards by the dialysis paper. The transparent film and dialysis paper are pressed together between two bonding pressure rollers 237. At the same time, the sprocket conveyor 31 is started, and the sprocket conveyor... Machine 31 drives the mounting frame 32 to move, and the mounting frame 32 drives the packaging box 33 to move synchronously to below the transparent film. The setting of the air blocking block 235 ensures that the transparent film will detach from the adsorption of the rotating drum 234 after it is attached to the dialysis paper, thus avoiding the situation where the transparent film is not firmly attached to the dialysis paper and is carried away by the rotating drum 234. The packaging box 33 is synchronously transported to below the dialysis paper by the sprocket conveyor 31, so that the side of the dialysis paper with the transparent film attached is located inside the packaging box 33, which is convenient for subsequent processing and production.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
