Description

Technical Field

[0001] The utility model belongs to the technical field of micro-needle patch machines and relates to an anti-adhesion structure of a micro-needle patch machine. Background Art

[0002] When producing microneedle eye patches, it is necessary to cut the release paper and the backing glue, and then place the cut hyaluronic acid microneedle sheets on the backing glue. However, during the cutting process of the backing glue, the backing glue is easily adhered to the roller knife, resulting in the cut product adhering to the roller knife. The existing method is to spray the release agent, but the lubricating effect of the release agent is short-lived and the amount of release agent sprayed cannot be quantified, which affects the yield of the microneedle eye patch.

[0003] In response to the above-mentioned problems, anti-adhesion structures have been developed. For example, the Chinese patent application [Authorization Announcement No.: CN217414253U] discloses an optical adhesive knife sticking device, including an oil storage roller for storing lubricating oil, an oil evenly distributed roller for controlling the oil output of the oil storage roller, a knife die, and an oil coating roller for transferring the lubricating oil to the knife die. The oil storage roller, the oil evenly distributed roller, the oil coating roller and the knife die are arranged in parallel in sequence and are transmission connected. The oil storage roller is a felt roller or a foam roller, the oil evenly distributed roller is a steel roller, and the oil coating roller is a rubber-coated roller.

[0004] The above structure is provided with an oil coating roller, an oil evenly distributing roller and an oil storage roller. When the knife die rotates, the above three are driven to rotate synchronously, so that the lubricating oil stored in the oil storage roller is successively transferred and coated on the knife die through the oil evenly distributing roller and the oil coating roller, thereby realizing the anti-sticking of the knife die. However, when used for a long time, it is necessary to add oil to the oil storage roller from time to time, and the setting of the oil coating roller, the oil evenly distributing roller and the oil storage roller makes the entire processing parts complicated, further increasing the difficulty of installation and processing. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose an anti-adhesion structure for a microneedle patch machine. The technical problem to be solved by the utility model is: how to solve the problem that the anti-adhesion structure of the existing microneedle patch machine is difficult to install.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A microneedle patch machine anti-adhesion structure, the microneedle patch machine includes a roller cutter, the outer side wall of the roller cutter has a plurality of annular blades, the anti-adhesion structure includes an anti-adhesion foam fitted on the outer side of the roller cutter blade, and is characterized in that the anti-adhesion structure also includes an anti-adhesion ring or an anti-adhesion sheet made of anti-adhesion material and bonded to the outer side wall of the roller cutter, the anti-adhesion ring is annular, the inner side of each blade is provided with the above-mentioned anti-adhesion ring or multiple anti-adhesion sheets, the blade includes two cutting walls arranged obliquely outward, the end wall of the anti-adhesion ring or anti-adhesion sheet close to the blade side is a vertically arranged support wall, and a clearance gap is provided between the cutting wall and the support wall on the side of the blade close to the anti-adhesion ring or anti-adhesion sheet.

[0008] Working principle: when cutting the microneedle patch, since the microneedle patch has a backing film with high viscosity, anti-sticking foam is attached to the outer side of the roller blade during cutting, and an anti-sticking ring or multiple anti-sticking films are arranged on the inner side of the roller blade. By arranging anti-sticking rings, anti-sticking films or anti-sticking foams on the inner and outer sides of the roller, the inside and outside anti-sticking effect of the roller is achieved. In order to ensure the use effect of the roller, the blade has two cutting walls inclined outward, the anti-sticking ring or the anti-sticking film has a vertically arranged supporting wall, and there is a clearance between the cutting wall and the supporting wall, so that when the blade cuts the microneedle patch, the anti-sticking film or the anti-sticking ring will not block the blade edge after being squeezed and deformed, thereby ensuring fast and stable cutting of the blade. The anti-sticking ring and the anti-sticking film are directly bonded to the roller by pasting, so that the installation of the anti-sticking ring and the anti-sticking film is convenient, and the stable use of the roller blade is ensured by setting the clearance.

[0009] In the above-mentioned anti-adhesion structure of the microneedle patch machine, the anti-adhesion ring, the anti-adhesion sheet and the anti-adhesion foam are all against the lower end of the blade.

[0010] The arrangement of this structure enables the anti-sticking ring, anti-sticking sheet and anti-sticking foam to be closer to the blade edge, which can achieve a better anti-sticking effect without affecting the cutting of the blade. The lower end of the blade can also be limited, making the anti-sticking ring, anti-sticking sheet and anti-sticking foam easy to install.

[0011] In the above-mentioned anti-adhesion structure of the microneedle patch machine, the blades are all in annular shape, and the inner side of each blade is provided with the above-mentioned anti-adhesion ring in an annular shape. The blades are divided into multiple groups, and each group of blades is evenly spaced along the radial direction of the roller cutter.

[0012] The blade is in the shape of a circular ring. In actual production, the size of the blade is relatively small. Therefore, during processing, an annular anti-sticking ring is required to prevent it from sticking circumferentially without intervals, so that the anti-sticking structure can achieve a better anti-sticking effect.

[0013] In the above-mentioned anti-adhesion structure of the microneedle patch machine, the outer side wall of the roller knife is provided with an anti-adhesion strip made of anti-adhesion material at the interval between each set of blades, and the anti-adhesion strip is arranged between two adjacent blades.

[0014] The stickiness at the intervals between each set of blades is also relatively large, so the provision of anti-stick strips improves the anti-stick effect between the microneedle patch and the blades after cutting.

[0015] Existing anti-sticking rings and anti-sticking strips all use snakeskin tape for anti-sticking, and the anti-sticking effect of snakeskin tape is better than that of foam.

[0016] In the above-mentioned anti-adhesion structure of the microneedle patch machine, the blade is in the shape of a long strip, and the blades are combined to form a circular cutting inner cavity. The above-mentioned anti-adhesion sheet is provided on the inner side of each blade. The anti-adhesion sheet is in the shape of a long strip, one end of the anti-adhesion sheet is connected to the blade, and the other end is located in the circular cutting inner cavity.

[0017] When the blade is in the shape of a long strip, the length of the blade is relatively long, so only an anti-sticking sheet needs to be provided on the inner side of the blade. By connecting one end of the anti-sticking sheet to the blade and the other end being located in the annular cut inner cavity, since the blade is in the shape of a long strip, it is relatively difficult to provide a corresponding annular anti-sticking sheet in production and installation. Therefore, a design of multiple anti-sticking sheets is adopted, which is not only easy to install but also can play a good anti-adhesion effect.

[0018] In the above-mentioned anti-adhesion structure of the microneedle patch machine, a plurality of anti-adhesion sheets are evenly spaced and distributed along the inner circumference of the blade.

[0019] The arrangement of this structure enables the anti-adhesion sheet to have a uniform anti-adhesion effect on the inner side of the blade, thereby improving the stability of the anti-adhesion structure.

[0020] In the above-mentioned anti-adhesion structure of the microneedle patch machine, the thickness of the anti-adhesion ring and the anti-adhesion sheet is slightly greater than the height of the blade.

[0021] The arrangement of this structure enables the anti-sticking ring and the anti-sticking sheet to contact the microneedle patch first when the blade is cutting, thereby achieving a better anti-sticking effect.

[0022] In the above-mentioned anti-adhesion structure of the microneedle patch machine, the end of the anti-adhesion foam close to the blade has a vertically arranged yield wall, and a deformation gap is provided between the cutting wall on the side of the blade close to the anti-adhesion foam and the yield wall.

[0023] The setting of the deformation gap allows the anti-sticking foam to have a certain deformation space after being squeezed during the downward pressing process of the blade, thereby avoiding the influence of the deformation of the anti-sticking foam on the blade and further improving the stability of the anti-sticking structure.

[0024] Compared with the prior art, the anti - adhesion structure of this microneedle mounter has the following advantages: By providing a clearance gap between the cutting wall and the supporting wall, when the blade cuts the microneedle patch, the anti - adhesion sheet or anti - adhesion ring will not be squeezed and deformed to block the blade edge, ensuring fast and stable cutting of the blade. The above - mentioned anti - adhesion ring and anti - adhesion sheet are directly adhered to the roller cutter by pasting, making the installation of the anti - adhesion ring and anti - adhesion sheet convenient. And through the setting of the clearance gap, the stability of the blade of the roller cutter is ensured. BRIEF DESCRIPTION OF THE DRAWINGS
