Description

Technical Field

[0001] The utility model relates to the technical field of medical adhesive tape production, in particular to a die-cutting roller for punching holes in medical adhesive tape. Background Art

[0002] The medical tape market is huge and is mainly divided into two categories: medical tape rolls and medical tape patches. With the aging population and the improvement of medical standards, the global medical tape market demand has increased year by year. Medical tape is mainly used to fix wounds, fix drugs, and conceal wounds. It has the advantages of being non-allergic to the skin, non-toxic, and without side effects. It has good breathability, does not damage the skin, and has long-lasting adhesion. When producing breathable medical tape, a die-cutting roller is required to make holes in the tape. After the holes are opened, the waste generated by the opening falls on the die-cutting roller, which is inconvenient to collect and process the waste on the die-cutting roller. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings in the prior art that waste generated by opening holes falls on the die-cutting roller, making it inconvenient to collect and process the waste on the die-cutting roller, and to propose a die-cutting roller for punching holes in medical tape.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A die-cutting roller for punching holes in medical tape is designed, comprising a first mounting plate, to which a roller is rotatably connected, a groove being provided at one end of the roller, through holes being provided on the groove at equal intervals along the axis, each through hole being connected to a rolling cutting blade, a guide mechanism being plugged into the groove, one end of the guide mechanism being connected to a collecting mechanism, a suction pump being fixedly connected to the first mounting plate, and the suction pump inlet being connected to the collecting mechanism via a connecting pipe.

[0006] Preferably, the guide mechanism includes a connector, which is plugged into the groove. One side of the connector is connected to a conduit, and one end of the conduit is connected to the collecting mechanism.

[0007] Preferably, a scraper strip is fixedly connected to the other side of the connector, and the scraper strip is in contact with the groove.

[0008] Preferably, the collecting mechanism includes an open cylinder, which connects the conduit and the connecting pipe. Two symmetrically arranged chutes are provided in the open cylinder, a filter assembly is slidably connected between the two chutes, and an end cover is connected to the opening of the open cylinder.

[0009] Preferably, the filter assembly includes two second mounting plates arranged in parallel, the two second mounting plates arranged in parallel are slidably connected to the corresponding chute, and an arc-shaped perforated plate is fixedly connected between the two second mounting plates.

[0010] Preferably, a baffle is fixedly connected to the bottom end of the arc-shaped perforated plate, and the baffle is arranged to be inclined toward the concave surface of the arc-shaped perforated plate.

[0011] The utility model provides a die-cutting roller for punching holes in medical tape, which has the following beneficial effects:

[0012] After the suction pump is started, the gas in the collecting mechanism is sucked, the collecting mechanism sucks the gas in the guide mechanism, and the guide mechanism sucks the gas in the groove, so that negative pressure is generated in the groove. The generated negative pressure sucks the punching waste cut by the rolling cutting blade, and the waste passes through the guide mechanism into the collecting mechanism. The collecting mechanism collects the punching waste, which is convenient for collecting the waste generated by punching. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1-2A die-cutting roller for punching holes in medical adhesive tape comprises a first mounting plate 1, a pressing roller 2 is rotatably connected to the first mounting plate 1, a groove 3 is provided at one end of the pressing roller 2, through holes are provided on the groove 3 at equal intervals along the axis direction, each through hole is connected to a rolling cutting blade 4, a guide mechanism 5 is plugged into the groove 3, one end of the guide mechanism 5 is connected to a collecting mechanism 6, a suction pump 7 is fixedly connected to the first mounting plate 1, and the inlet of the suction pump 7 is connected to the collecting mechanism 6 through a connecting pipe.

[0020] Working process:

[0021] After the pressure roller 2 rotates, it drives the rolling cutting blade 4 to rotate, and the medical tape is punched by the rolling cutting blade 4. At the same time, the suction pump 7 is powered on and started. After the suction pump 7 is started, it absorbs the gas in the collecting mechanism 6, and the collecting mechanism 6 absorbs the gas in the guide mechanism 5. The guide mechanism 5 absorbs the gas in the groove 3, so that a negative pressure is generated in the groove 3. The generated negative pressure absorbs the punching waste cut by the rolling cutting blade 4, and the waste passes through the guide mechanism 5 into the collecting mechanism 6. The collecting mechanism 6 collects the punching waste, which is convenient for collecting the waste generated by punching.

[0022] Example 2: In Example 1, when the waste is guided by the guide mechanism 5, the waste entering the groove 3 is adhered to the inner wall of the groove 3, which makes it inconvenient to guide the waste. Figure 3 As another preferred embodiment of the present invention, the difference from Example 1 is that the guide mechanism 5 includes a connector 51, which is inserted into the groove 3, and one side of the connector 51 is connected to a conduit 52, one end of the conduit 52 is connected to the collecting mechanism 6, and the other side of the connector 51 is fixedly connected to a scraper 53, which contacts the groove 3, the conduit 52 fixes the connector 51, and the connector 51 fixes the scraper 53. After the pressure roller 2 rotates, it is relatively dislocated with the scraper 53, and the scraper 53 scrapes the waste on the groove 3 so that the waste will not stick to the groove 3.

[0023] Example 3: In Example 1, after the waste is collected, it is inconvenient to clean the waste in the collection mechanism 6. Figure 4 As another preferred embodiment of the present invention, the difference from embodiment 2 is that the collecting mechanism 6 includes an open cylinder 61, which connects the conduit 52 and the connecting pipe. The open cylinder 61 has two symmetrically arranged chutes, and a filter assembly 62 is slidably connected between the two chutes. The open end of the open cylinder 61 is connected to an end cap 63.

[0024] The filter assembly 62 includes two parallel second mounting plates 621, which are slidably connected to corresponding slide grooves. An arc-shaped perforated plate 622 is fixedly connected between the two second mounting plates 621, and a baffle 623 is fixedly connected to the bottom end of the arc-shaped perforated plate 622. The baffle 623 is tilted toward the concave surface of the arc-shaped perforated plate 622. After the gas and waste come into contact with the arc-shaped perforated plate 622, the gas passes through the arc-shaped perforated plate 622, and the waste is filtered out by the arc-shaped perforated plate 622. The filtered waste falls downward under its own gravity and is located between the arc-shaped perforated plate 622 and the baffle 623. When processing the waste, the end cover 63 is removed, and the arc-shaped perforated plate 622 is pulled out and cleaned, which is convenient for processing the collected waste.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
