Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical machinery, in particular to a large-capacity injection non-PVC co-extrusion film cutting device. Background Art

[0002] Non-PVC soft bag infusion is also called polyolefin composite film and polyolefin multi-layer co-extruded film. Now in the large infusion industry, non-PVC composite film soft bags are generally used to replace glass bottles for infusion packaging. The soft bag is made of three-layer co-extruded film without using adhesives. The film cleaning and soft bag forming are all completed in a Class 100 clean workshop. It is pyrogen-free and particle-free. In the production process of non-PVC composite film, the co-extruded film needs to be cut first. Therefore, we have launched a large-volume injection non-PVC co-extruded film cutting equipment.

[0003] The existing patent (publication number: CN209215035U) discloses a large-capacity injection non-PVC co-extruded film cutting device, which includes a base, a guide platform and a tool fixing plate are arranged on the base through an oil cylinder, a magnetic combination tool is connected through the fixing plate, and a guide rod is also arranged on the base and a mold mounting plate and a vacuum template are connected through the guide rod; the cutting device with this structure can adsorb the non-PVC co-extruded film on the vacuum template through the negative pressure generated by the vacuum, and cut it through magnetic combination tools of different combinations, so as to achieve the cutting of samples of different shapes and sizes, greatly improve the work efficiency, and ensure the accuracy of the inspection data. In the process of realizing the utility model, the inventor found that the prior art has the following problems: 1. The existing cutting equipment tool is set at the bottom and directly exposed to the outside, which is very dangerous for workers to unload the cut film, and personal safety is not guaranteed; 2. The scraps generated by the existing cutting equipment during cutting will directly fall on the base, which requires subsequent manual cleaning, which is very time-consuming and laborious.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: a large-capacity injection non-PVC co-extruded film cutting device, comprising a base 1, four pillars 2 are fixedly connected to the top of the base 1, a top plate 3 is fixedly connected between the top ends of the four pillars 2, a vacuum pump 4 and a cleaning component 5 are respectively provided on the top of the top plate 3, the bottom of the vacuum pump 4 passes through the top plate 3 and is connected to the vacuum template 6, and a cutting component 7 is provided in the middle of the four pillars 2.

[0020] In this embodiment, Figure 1 and Figure 3 As shown, the cleaning assembly 5 is fixedly connected to the first motor 501 on the rear side of the top plate 3, the output end of the first motor 501 is fixedly connected to the first threaded rod 502, the first threaded rod 502 passes through the middle of the moving block 503, and the bottom of the moving block 503 is fixedly connected to a cleaning scraper 504.

[0021] In this embodiment, Figure 3 As shown, the moving block 503 is an "I"-shaped structure, and the moving block 503 is slidably connected in the slide groove 505 in the middle of the top plate 3 to form a sliding structure; this structure can limit the moving block 503 while enabling the moving block 503 to slide along the slide groove 505, thereby driving the cleaning scraper 504 at the bottom to clean the cut scraps.

[0022] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cutting assembly 7 includes a second motor 701 fixedly connected to one side of the pillar 2, the output end of the second motor 701 is fixedly connected to the second threaded rod 702, the middle part of the second threaded rod 702 is threadedly connected to the mounting plate 703, the top of the mounting plate 703 is fixedly connected to two cylinders 704, the output ends of the two cylinders 704 are fixedly connected to a cutting plate 705, the top surfaces of the cutting plate 705 are respectively fixedly connected to cutting knives 706 and four springs 707, a protective shell 708 is fixedly connected between the top ends of the four springs 707, a cutting opening 709 is opened in the middle of the top surface of the protective shell 708, two groups of limit plates 7010 are arranged on the top of the cutting opening 709, a storage box 7011 is fixedly connected to the front side of the protective shell 708, and a limit rod 7012 passes through one side of the middle part of the mounting plate 703.

[0023] In this embodiment, Figure 3 and Figure 4 As shown, an elastic structure is formed between the cutting board 705 and the protective shell 708 through the spring 707, and the protective shell 708 wraps the cutting board 705 inside it. A slot is provided at the bottom of the cutting board 705, and the output ends of the two cylinders 704 pass through the slot and are connected to the cutting board 705; this structure enables the cylinder 704 to push the cutting board 705 to drive the cutting knife 706 to rise synchronously, and during the rising process, the protective shell 708 always protects the cutting knife 706 inside to prevent external staff from directly contacting the cutting knife 706 and getting injured.

[0024] In this embodiment, Figure 2As shown, two raised contact edges are provided on both sides of the vacuum template 6, and the height of the two contact edges is greater than the thickness of the vacuum template 6; the contact edges can first contact with the protective shell 708 when the cutting component 7 rises, and then the protective shell 708 stops moving due to resistance, and the cutting plate 705 will continue to drive the cutting knife 706 to rise under the action of the cylinder 704. The cutting plate 705 will squeeze the spring 707 during this process until the cutting knife 706 cuts off the co-extruded film on the vacuum template 6. This structure can expose the cutting knife 706 only when cutting is required.

[0025] The use method and advantages of the utility model: When the large-capacity injection non-PVC co-extrusion film cutting device is used, the working process is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first turn on the vacuum pump 4 to adsorb the co-extruded film to be cut on the vacuum template 6. When the co-extruded film is fixed, start the second motor 701 to drive the second threaded rod 702 to rotate. The rotation of the second threaded rod 702 will drive the mounting plate 703 to move, thereby driving the upper cutting knife 706 to move synchronously until the cutting knife 706 is moved to the part that needs to be cut. Then the cylinder 704 pushes the cutting plate 705 to rise. The rising of the cutting plate 705 will synchronously drive the protective shell 708 and the cutting knife 706 to rise. When the protective shell 708 rises to a certain height, it will contact the contact edges on both sides of the vacuum template 6. At this time, the protective shell 708 is blocked and stops, and the internal cutting plate 705 will continue to drive the cutting knife 706 to move upward. The cutting plate 705 squeezes the spring 707, and finally the cutting knife 706 extends from the cutting opening 709 to the vacuum template. 6 is cut. After the cutting is completed, the cylinder 704 shrinks. After the protective shell 708 is separated from the contact edge, the cutting knife 706 is driven to shrink into the protective shell 708 under the action of the spring 707. The protective shell 708 can protect the cutting knife 706 well inside it to prevent the staff from accidentally touching the cutting knife 706 and getting injured. Moreover, the cut scraps will fall into the two sets of limit plates 7010 on the top surface of the protective shell 708 under the action of gravity. After the cutting is completed, the mounting plate 703 is reset, and the first motor 501 is started to drive the first threaded rod 502 to rotate. The rotation of the first threaded rod 502 will drive the cleaning scraper 504 at the bottom to move through the moving block 503, and the co-extruded film scraps on the top surface of the protective shell 708 are pushed into the storage box 7011 to complete the collection of waste materials, thereby preventing the waste materials from falling directly on the base 1 and performing additional cleaning.
