Description

Technical Field

[0001] The utility model relates to a rubber plaster processing device, and more specifically to a laser punching device for rubber plaster that reduces the loss of drug properties. Background Art

[0002] Medical rubber plasters are adhered to the skin surface. To increase air permeability and keep the skin healthy, it is necessary to punch holes in the rubber plaster.

[0003] Generally, rubber plaster products use a mechanical structure and punch holes using a mold. Different molds are used for punching rubber plasters of different specifications. Each time for products of different specifications, the corresponding mold needs to be replaced according to the specifications when punching holes. There are problems of low punching efficiency and fast mold wear. In addition, when punching holes using a mold, affected by the size and hardness of the mold, there is also a problem that the punched holes are generally relatively large.

[0004] To solve the above problems existing in mold punching, the Chinese utility model patent CN201211688Y discloses a laser on-line punching device for medical thin materials. The device includes a material feeding mechanism and a slicing mechanism, and a laser marking device is fixed above the fabric between the material feeding mechanism and the slicing mechanism. The laser marking device tracks the position of the processed material through a displacement sensor or a photoelectric limit switch installed on the cutter of the slicing mechanism, and controls the laser marking device to punch holes.

[0005] The principle of punching holes by the laser marking device is: based on the thermophysical process of the interaction between the laser and the material. The laser beam is highly focused through an optical system to form an extremely small light spot and concentrate energy. After the processed material absorbs the laser energy, the local temperature rises rapidly, and the punched area is ablated into a hole. The problems existing in the Chinese utility model patent CN201211688Y are: (1) The ablation gas, fine particles, etc. generated during the punching process are not collected and processed, which is not beneficial to the environment and also not conducive to keeping the produced rubber plaster clean; (2) The temperature of the rubber plaster being punched is relatively high during the punching process, which easily leads to the loss of drug properties. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a laser punching device for rubber plaster that reduces the loss of drug properties. During the laser punching process, this device can collect the ablation gas and fine particles generated during punching, keep the production environment clean, and prevent the rubber plaster product from being soiled; it can also reduce the temperature of the rubber plaster during the punching process, keep the rubber plaster at a relatively low temperature, and reduce the loss of drug properties.

[0007] To solve the above technical problems, the utility model adopts the following technical means:

[0008] A laser punching device for rubber plaster that reduces the loss of drug properties, including a punching box body and a laser puncher;

[0009] The two ends of the described punching box body are open. One end serves as the inlet for conveying the rubber plaster, and the other end serves as the outlet for conveying the rubber plaster. Inside the punching box body, there are an upper cover and a lower cover.

[0010] There is a passage interval between the upper cover and the lower cover, and the rubber plaster is conveyed along the passage interval. The upper cover is provided with a cooling gas inlet pipe, and the lower cover is provided with a cooling gas outlet pipe. The cooling gas outlet pipe is provided with a cooling gas collection pipe. The cooling gas collection pipe is arranged at the bottom of the upper cover and above the rubber plaster. One end of the cooling gas collection pipe is connected to the cooling gas outlet pipe, and the other end of the cooling gas collection pipe is closed. A gas inlet hole is provided on the side of the cooling gas collection pipe facing the rubber plaster. The gas inlet holes are arranged at intervals along the cooling gas collection pipe. The cooling gas outlet pipe is provided with a lower cover gas outlet at the bottom surface of the lower cover.

[0011] At the bottom inside the upper cover, there is a laser punching machine, which is arranged above the rubber plaster.

[0012] The working principle of the present utility model is as follows:

[0013] (1) The rubber plaster is input through the inlet of the punching box body, passes through the passage interval between the upper cover and the lower cover, and then is output from the conveying outlet of the punching box body.

[0014] (2) The laser punching machine punches the conveyed rubber plaster.

[0015] (3) During the punching process, the cooling gas inlet pipe inputs the cooling gas into the upper cover, and the gas flows downward. A part of the gas flows out of the upper cover through the cooling gas collection pipe. During the outflow process, the ablation gas and fine particles in the upper cover after punching are output together; thus, the temperature inside the upper cover is relatively low and remains clean. When the gas in the upper cover flows downward, a part of the gas also flows into the lower cover through the holes punched in the rubber plaster. During the flowing process, the temperature of the rubber plaster is further reduced, and then it flows out of the lower cover through the lower cover gas outlet. During the outflow process, the ablation gas and fine particles are output from the lower cover together, and the temperature inside the lower cover is relatively low and remains clean.

[0016] The present utility model adopting the above technical solution, compared with the prior art, its prominent feature is:

[0017] During the laser punching process of this device, it can collect the ablation gas and fine particles generated by punching, keep the production environment clean, and prevent the rubber plaster product from being soiled; it can also reduce the temperature of the rubber plaster during the punching process, keep the rubber plaster at a relatively low temperature, and reduce the loss of medicinal properties.

[0018] The further preferred technical solution is as follows:

[0019] The punching box body is a cuboid box body, and the punching box body is provided with a box body side plate, a box body top plate, and a box body bottom plate. With the above settings, the box body cooperates with the upper cover and the lower cover to form a punching space, so that the air flow in the space mainly flows inside the upper cover and between the upper cover and the lower cover.

[0020] The cross-sections of the upper cover and the lower cover are both isosceles trapezoids. The bottom surface of the upper cover is open, and the top surface is smaller; the top surface of the lower cover is open, and the bottom surface is smaller.

[0021] With the above settings, it is convenient for the gas flowing inside the upper cover to cool the inside of the upper cover and discharge the ablation gas and fine particles. It is also convenient for the gas to flow between the upper cover, the holes, and the lower cover, to cool down and discharge the ablation gas and fine particles.

[0022] The cooling gas input pipe is connected to the first rubber paste cooling pipe. The first rubber paste cooling pipe is arranged at the bottom of the upper cover and above the rubber paste. The first rubber paste cooling pipe and the cooling gas collection pipe are respectively located at the inlet and outlet of the punching box body.

[0023] Through the above settings, the gas flow inside the upper cover flows from the inlet of the punching box body to the outlet, and is collected and discharged by the cooling gas collection pipe at the outlet.

[0024] The cooling gas input pipe is also connected to the second rubber paste cooling pipe. The second rubber paste cooling pipe is arranged on the top of the upper cover.

[0025] By setting the second rubber paste cooling pipe, the gas flow in the upper cover is more sufficient, and the cooling and exhaust effect is better. Brief Description of the Drawings
