Description

Technical Field

[0001] This utility model relates to an infusion patch preparation machine, and more specifically to a window opening device for an infusion patch preparation machine. Background Technology

[0002] Disposable IV dressings are medical supplies mainly used to fix IV needles, prevent infection, and protect the puncture site. The specific method of use is to apply the IV dressing to the puncture site after the needle is inserted, thereby fixing the needle in place.

[0003] In the production process of IV patch, it is often necessary to perform a windowing operation on the adhesive tape. This operation removes the base material from the tape, leaving only the transparent adhesive film. This allows users to easily align the sponge with the puncture site of the IV needle when fixing it in place. However, the current windowing operation is done manually, which is not only inefficient but also results in a low yield rate. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a window opening device for an infusion patch preparation machine that can realize automated window opening operation, high efficiency and high yield.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a window opening device for an infusion patch preparation machine, characterized in that it includes a traction mechanism and a window opening mechanism. The traction mechanism is positioned between the window opening mechanism and the belt pulley, and the adhesive tape pulled out by the traction belt pulley is fed into the window opening mechanism to open the window. The traction mechanism includes a traction base, an upper traction roller, and a lower traction roller. The traction base is installed on the frame between the window opening mechanism and the belt pulley. The upper traction roller and the lower traction roller are rotatably mounted on the traction base and are distributed vertically on the traction base, forming a traction channel for the adhesive tape between them.

[0006] As a further improvement of this utility model, the window opening mechanism includes a window opening base, an upper window opening roller, a lower window opening roller, and a slag discharge assembly. The upper and lower window opening rollers are rotatably mounted on the window opening base. The window opening base is mounted on the frame at a position away from the belt pulley of the traction mechanism. The roller surface of the lower window opening roller is provided with a window opening groove. The upper and lower window opening rollers are distributed vertically on the window opening base, forming a window opening channel between them to open the lower side of the belt. The slag discharge assembly is located on the side of the window opening base opposite to the traction mechanism to discharge slag from the belt that has passed through the window opening channel.

[0007] As a further improvement of this utility model, the slag discharge assembly includes a slag discharge base, a slag discharge roller, and a slag discharge scraper. The slag discharge base is fixed on the side of the window-opening base, the slag discharge roller is rotatably mounted on the slag discharge base, and the slag discharge scraper is mounted on the slag discharge base and is located on the side of the slag discharge roller facing away from the window-opening base.

[0008] As a further improvement of this utility model, the slag discharge roller includes a slag discharge shaft and a guide shaft. The slag discharge shaft is installed between the guide shaft and the slag discharge scraper. The conveyor belt first passes around the guide shaft and then around the slag discharge shaft before being fed into the next station. The slag discharge scraper and the slag discharge shaft are both rotatably mounted on the slag discharge base. The slag discharge base is provided with handwheels for adjusting the rotatability angle of the slag discharge scraper and the slag discharge shaft, respectively.

[0009] The beneficial effects of this utility model are that, through the setting of the traction mechanism and the window opening mechanism, the traction mechanism can effectively pull the tape into the window opening mechanism, and then the window opening mechanism can simply and effectively achieve the effect of opening the window. By using the upper traction roller and the lower traction roller to form a traction channel, the traction of the tape can be effectively achieved through the combination of the upper traction roller and the lower traction roller.

[0011] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0012] Reference Figure 1As shown in this embodiment, a window-opening device for an infusion patch preparation machine is characterized by comprising a traction mechanism 61 and a window-opening mechanism 62. The traction mechanism 61 is positioned between the window-opening mechanism 62 and the belt pulley, and the adhesive tape pulled out by the belt pulley is fed into the window-opening mechanism 62 to open the window. The traction mechanism 61 includes a traction base 611, an upper traction roller 612, and a lower traction roller 613. The traction base 611 is installed on the frame between the window-opening mechanism 62 and the belt pulley. The upper traction roller 612 and the lower traction roller 613 are rotatably mounted on the traction base 611. The upper traction roller 612 and the lower traction roller 613 are arranged on the traction base 611 and distributed vertically, forming a traction channel for the traction belt between them. With the above structure, the traction belt can be pulled by the traction mechanism 61 and then opened by the window opening mechanism 62 in a simple and effective way. This can effectively ensure the stability of the belt feed, and make the window shape opened by the window opening mechanism 62 better and the position more accurate. With the above arrangement of the upper traction roller 612 and the lower traction roller 613, a traction channel can be formed simply and effectively, and the traction effect of the traction channel can be achieved by the action of the traction channel.

[0013] As an improved embodiment, the window opening mechanism 62 includes a window opening base 621, an upper window opening roller 622, a lower window opening roller 623, and a slag discharge assembly 624. Both the upper window opening roller 622 and the lower window opening roller 623 are rotatably mounted on the window opening base 621. The window opening base 621 is mounted on the frame at a position away from the belt pulley of the traction mechanism 61. The roller surface of the lower window opening roller 623 is provided with a window opening groove. The upper window opening roller 622 and the lower window opening roller 623 are distributed vertically on the window opening base 621. The two form an opening channel for opening the lower side of the tape. The slag discharge component 624 is set on the side of the opening base 621 facing away from the traction mechanism 61 to discharge the slag from the tape that has passed through the opening channel. By setting up the upper opening roller 622, the lower opening roller 623 and the slag discharge component 624, it is possible to effectively open the tape when it passes through the opening channel, and then remove the tape residue cut from the tape. This simple and effective method achieves the effect of automated opening.

[0014] As an improved specific implementation, the slag discharge assembly 624 includes a slag discharge base 6241, a slag discharge roller 6242, and a slag discharge scraper 6243. The slag discharge base 6241 is fixed on the side of the window opening base 621. The slag discharge roller 6242 is rotatably mounted on the slag discharge base 6241. The slag discharge scraper 6243 is mounted on the slag discharge base 6241 and is located on the side of the slag discharge roller 6242 facing away from the window opening base 621. After the tape window opening operation is completed, only the shape of the window is cut out on the tape. Therefore, it is necessary to remove the tape base inside the window shape. In this embodiment, the tape first wraps around the slag discharge roller 6242 to make the side of the tape base inside the window shape curl up. Then, the slag discharge scraper 6243 blocks the side of the tape base, thereby achieving the effect of tearing the tape base at the window shape off the tape when the tape continues to run around the slag discharge roller 6242.

[0015] As an improved specific implementation, the slag discharge roller 6242 includes a slag discharge shaft 62421 and a guide shaft 62422. The slag discharge shaft 62421 is installed between the guide shaft 62422 and the slag discharge scraper 6243. The conveyor belt first passes around the guide shaft 62422 and then around the slag discharge shaft 62421 before being fed into the next station. Both the slag discharge scraper 6243 and the slag discharge shaft 62421 are rotatably mounted on the slag discharge base 6241. The slag discharge base 6241 is provided with handwheels for adjusting the rotation angle of the slag discharge scraper 6243 and the slag discharge shaft 62421. With the above-mentioned structure, the slag discharge operation of the conveyor belt can be realized simply and effectively. Furthermore, by adopting the method that the slag discharge scraper 6243 and the slag discharge shaft 62421 are rotatably mounted on the slag discharge base 6241, the rotation angle of the slag discharge scraper 6243 and the slag discharge shaft 62421 can be effectively adjusted by handwheels, thereby better realizing the slag discharge function.

[0016] In summary, the window opening device of this embodiment, through the setting of the traction mechanism 61 and the window opening mechanism 62, can effectively pull the tape into the window opening mechanism 62 to open the window, thus realizing the automated window opening operation of the tape in a simple and effective way.
