Description

Technical Field

[0001] The invention belongs to the technical field of microneedle patch machines and relates to a waste material removing device of the microneedle patch machine. Background Art

[0002] The microneedle patch machine is a production equipment used to produce microneedle eye patches. Microneedle eye patches usually cut square microneedle sheets into smaller microneedle patches. The back patch and the release paper are bonded to each other to form a composite film. The composite film is cut into a shape suitable for the placement of the microneedle patch. The microneedle patch is placed on the cut composite film. The back patch adheres the microneedle patch to the composite film, and then the bonded composite film is cut to form multiple microneedle eye patches. In the above process, the composite film needs to be cut, and the composite film waste in block shape and the release paper waste in ring shape need to be cut out from the composite film. The release paper waste in ring shape needs to be peeled off from the backing adhesive. The backing adhesive has a large viscosity, such as Figure 1 As shown, after roller cutting, the annular waste cutting strip 104 and the block-shaped waste cutting block 105 need to be peeled off from the composite film 8 manually, resulting in a low production efficiency of the microneedle eye patch.

[0003] Therefore, a peeling knife is usually provided to peel it off. For example, Chinese patent application [authorization announcement number: CN214140928U] discloses a microneedle eye patch adhesive device, including a frame, on which a first low-viscosity film waste collection mechanism, a medical adhesive tape cutting mechanism, a medical adhesive tape feeding mechanism, a second low-viscosity film waste collection mechanism and a sheet product conveyor are arranged in sequence along the conveying direction of the microneedle eye patch, and a first peeling knife body is provided on the side of the first low-viscosity film waste collection mechanism facing the medical adhesive tape cutting mechanism, the first peeling knife body is connected to the medical adhesive tape cutting mechanism, and the second low-viscosity film waste collection mechanism is arranged on the side of the sheet product conveyor A second peeling knife body is provided on the side, and the second peeling knife body is connected to the sheet product conveyor. The frame is also provided with a first low-viscosity film waste winding roller, a medical adhesive waste winding roller, a low-viscosity film tape feeding roller, a medical adhesive tape feeding roller, a release film winding roller and a second low-viscosity film waste winding roller, and the first low-viscosity film waste winding roller is corresponding to the first low-viscosity film waste collecting mechanism, the medical adhesive waste winding roller is corresponding to the medical adhesive tape cutting mechanism, the low-viscosity film tape feeding roller, the medical adhesive tape feeding roller and the release film winding roller are all corresponding to the medical adhesive tape feeding mechanism, and the second low-viscosity film waste winding roller is corresponding to the second low-viscosity film waste collecting mechanism.

[0004] The above structure uses the first peeling knife body and the second peeling knife body to peel off the waste material after cutting, and the microneedle eye patch is attached near the human eye area, has a small size and a soft material, which causes it to partially adhere to the peeling knife body during the peeling process using the peeling knife body, affecting the peeling of the subsequent microneedle eye patch by the peeling knife body, resulting in some microneedle eye patches not being peeled off or still being adhered to the film, causing large errors in the secondary processing of the microneedle eye patch, reducing the yield of the microneedle eye patch, thereby affecting the production of the microneedle eye patch. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the prior art and to propose a waste removal device for a microneedle patch machine. The technical problem to be solved by the present invention is: how to solve the problem that waste from the prior microneedle patch machine easily remains on the membrane.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A waste removal device for a microneedle patch machine comprises a frame, wherein the frame is sequentially provided with an input roller and an output roller in the horizontal direction, both of which can be used for winding a composite film, and the frame is also provided with a cutting roller knife assembly 1 and a cutting roller knife assembly 2, both of which can cut the composite film, and the cutting roller knife assembly 1 and the cutting roller knife assembly 2 are located between the input roller and the output roller. It is characterized in that the waste removal device comprises an air pressure waste removal assembly arranged on the frame and a waste recovery roller that can retract the waste cutting strip, the air pressure waste removal assembly is arranged between the cutting roller knife assembly 1 and the cutting roller knife assembly 2, a separating roller is connected to the side of the cutting roller knife assembly 2 close to the cutting roller knife assembly 1, and a vertically movable punching rod is provided on the air pressure waste removal assembly, and the punching rod is located between the separating roller and the cutting roller knife assembly 1.

[0008] Working principle: The composite film formed by laminating the release paper and the adhesive sticker is rolled up on the input roller, and the composite film is successively passed through the cutting roller knife assembly 1 and the cutting roller knife assembly 2 and rolled up on the output roller. After the initial cutting by the cutting roller knife assembly 1, there are strip-shaped waste cutting strips and block-shaped waste cutting blocks on the composite film. The waste cutting blocks can be pushed downward by the punching rod of the air pressure waste removal assembly to achieve the removal of the waste cutting blocks. For the waste cutting strip, since only the waste cutting strip of the release paper attached to the adhesive is peeled off, the waste cutting strip has greater adhesion and is more firmly attached to the adhesive. The present application is to remove the waste cutting strip by removing the end of the waste cutting strip from the separation roller The waste cutting strip is pulled out and rolled up on the waste recycling roller. The rotation of the waste recycling roller can drive the waste cutting strip to wind up. Therefore, during continuous production, the cooperation of the waste recycling roller and the separating roller can synchronously peel off the waste cutting strip, so that the composite film after the initial cutting can be stably cut for the second time. Different from the existing form of using a peeling knife, the present application is based on the fact that the microneedle eye patch has a waste cutting strip and a waste cutting block after the initial cutting. By pulling and rolling up the waste cutting strip and pushing the waste cutting block downward through the punching rod, the waste cutting block and the waste cutting strip are ensured to be removed quickly and stably, thereby improving the stability of waste removal.

[0009] The waste recovery roller is driven to rotate by a motor, and other driving elements may also be used.

[0010] In the above-mentioned waste removal device of the microneedle patch machine, the waste recovery roller is located between the cutting roller knife assembly one and the cutting roller knife assembly two, and the waste recovery roller is arranged close to the cutting roller knife assembly one, and the waste recovery roller is arranged parallel to the separation roller.

[0011] By locating the waste recovery roller on one side of the separating roller, the waste recovery roller and the separating roller are arranged parallel to each other, and the waste recovery roller is close to one side of the cutting roller knife assembly, the waste cutting strips wound on the waste recovery roller and the separating roller form an angle less than 90 degrees. By setting the angle, the waste cutting strips on the separating roller can be quickly peeled off, thereby improving the convenience and stability of removing the waste cutting strips.

[0012] In the above-mentioned waste removal device of the microneedle patch machine, the waste recovery roller is provided with a laminating belt which is laminated along the length direction of the waste recovery roller.

[0013] The bonding tape is set so that the end of the waste cutting strip is attached to the waste recovery roller through the bonding tape. When the waste recovery roller rotates, the waste recovery roller can also quickly and synchronously remove the waste cutting strip when the composite film is processed. The waste cutting strip can be removed while ensuring the stable processing of the microneedle eye patch, without affecting the production efficiency of the microneedle eye patch.

[0014] In the above-mentioned waste removal device of the microneedle patch machine, an elastic input roller and an elastic output roller are provided on the frame, and the elastic input roller is connected with an elastic film that passes through the cutting roller knife component one and the cutting roller knife component two and is rolled up on the elastic output roller. The waste removal device also includes a waste recovery rack, and the waste recovery rack has a support plate fixed on the cutting roller knife component two, and the support plate is horizontally arranged, and the support plate is located below the separating roller and the upper side wall of the support plate is close to the lower side wall of the separating roller, and there is a gap between the support plate and the separating roller for the composite film to pass through, and the elastic membrane located between the cutting roller knife component one and the cutting roller knife component two is arranged below the support plate.

[0015] By setting the upper side wall of the support plate and the lower side wall of the separating roller close to each other, when the end of the waste cutting strip is pulled out, the waste will not fall downward but move along the gap between the support plate and the separating roller, thereby preventing the waste cutting strip from falling on the elastic membrane and sticking to it, and the subsequent cutting of the cutting roller knife assembly 2 is more stable. The horizontal setting of the support plate also has the effect of making way for the elastic membrane, further improving the stability of the removal of the waste cutting strip and the stability of the subsequent composite film cutting.

[0016] On the one hand, the elastic film plays a buffering role during cutting or pressing. On the other hand, since the thickness of the composite film is very small, for composite films of different thicknesses, the present application adopts the method of replacing elastic films of different thicknesses to realize the processing of composite films of different thicknesses, thereby realizing the adjustment of multiple workstations and improving the production efficiency and versatility of the production equipment.

[0017] In the above-mentioned waste removal device of the microneedle patch machine, a connecting seat is connected to the bottom of the support plate, and a strip-shaped connecting hole is vertically opened on the connecting seat. The cutting roller knife assembly 2 includes two mounting plates arranged opposite to each other in the longitudinal direction, and a plurality of mounting holes are opened on the side walls of the mounting plates. The connecting seat slides along the mounting plate, and the connecting seat and the mounting plate are fixedly connected by fasteners passing through the connecting holes and the mounting holes in sequence.

[0018] By setting the connecting seat, it is ensured that the support plate has strong support, which can improve the support strength of the composite film after cutting, and can adjust the distance between the support plate and the separating roller. By adjusting the distance between the two, it is convenient for the composite film after cutting to pass through, and it can also play a certain limiting role, making the installation between the support plate and the separating roller more convenient.

[0019] In the waste removal device of the above-mentioned microneedle patch machine, a supporting roller 2 and a cutting roller 2 distributed up and down are rotatably connected between the two mounting plates, and a cutting gap is formed between the supporting roller 2 and the cutting roller 2, and the cutting gap is arranged opposite to the gap.

[0020] By arranging the cutting gap and the clearance to face each other, when the waste cutting strip is removed, the original traveling path of the composite film is not affected, and the production speed and production efficiency of the composite film are not affected.

[0021] In the waste removal device of the above-mentioned microneedle patch machine, the punching rods are provided in multiple groups, and each group of punching rods is correspondingly provided with a punching pipe, and the punching pipe can push the corresponding punching rod to move downward and push out the waste.

[0022] Multiple sets of punching rods can correspond to microneedle patches of different shapes. Some microneedle patches are long and strip-shaped, and multiple punching rods are needed to punch a waste cutting block. Some microneedle patches are smaller circles, so only one punching rod is needed to punch a waste cutting block. In addition, when producing microneedle patches of different shapes, it is sufficient to start the corresponding punching pipeline, thereby improving the applicability of the pneumatic waste removal component.

[0023] The pneumatic waste removal assembly includes a mounting seat, on which a plurality of waste cylinders are arranged. A stamping pipeline is connected and communicated with an external air pipe. The gas of the external air pipe is supplied to the waste cylinder through the stamping pipeline. The waste cylinder pushes the stamping rod to move downward and pushes out the waste cutting block.

[0024] In the above-mentioned waste removal device of the microneedle patch machine, the cutting roller knife assembly 1 includes a supporting roller 1 and a cutting roller 1 distributed up and down, and the waste recovery rack also includes a guide plate arranged obliquely downward, the upper end of the guide plate is close to between the supporting roller 1 and the cutting roller 1, and the lower end of the guide plate is located outside the cutting roller knife assembly 1.

[0025] The setting of the guide plate is to prevent some waste cutting blocks from falling directly onto the support roller 1 under the action of their own gravity, so as to facilitate the collection of the waste cutting blocks and improve the stability of the operation of the microneedle placement machine.

[0026] In the above-mentioned waste removal device of the microneedle patch machine, the lower end of the guide plate is bent to form a waste lead-out plate, and the waste lead-out plate is bent to form a discharge groove inclined from front to rear.

[0027] The waste material outlet plate and the discharge trough are arranged so that the waste material cutting blocks can be quickly accumulated in the discharge trough, which is convenient for removing the waste material cutting blocks.

[0028] In the above-mentioned waste removal device of the microneedle patch machine, the cutting roller 2 includes a cylindrical roller wall, a plurality of annular blades are provided on the roller wall, an anti-sticking ring or an anti-sticking sheet is provided on the roller wall, and the inner side of each blade is provided with the above-mentioned anti-sticking ring or multiple above-mentioned anti-sticking sheets.

[0029] The arrangement of this structure enables the anti-sticking effect of cutting roller 2 to be improved by providing an anti-sticking ring or a sticking sheet to prevent the outer edge of the composite film from adhering to the blade of the cutting roller when the composite film passes through the secondary cutting of cutting roller knife assembly 2.

[0030] Compared with the prior art, the waste removal device of the microneedle patch machine has the following advantages:

[0031] 1. During continuous production, the cooperation of the waste recovery roller and the separation roller can synchronously peel off the waste cutting strips, so that the composite film after the initial cutting can be stably cut for the second time. Different from the existing form of using a peeling knife, this application is based on the fact that the microneedle eye patch has waste cutting strips and waste cutting blocks after the initial cutting. By pulling and rolling up the waste cutting strips and pushing the waste cutting blocks downward through the punching rod, the waste cutting blocks and waste cutting strips are ensured to be removed quickly and stably, thereby improving the stability of waste removal.

[0032] 2. By locating the waste recovery roller on one side of the separation roller, the waste recovery roller is arranged parallel to the separation roller, and the waste recovery roller is close to one side of the cutting roller knife assembly, the waste cutting strips wound on the waste recovery roller and the separation roller form an angle less than 90 degrees. By setting the angle, the waste cutting strips on the separation roller can be quickly peeled off, thereby improving the convenience and stability of removing the waste cutting strips.
