Description

Film agent conveying and cutting mechanism

Technical Field

The application relates to a cutting structure of a film agent, in particular to a film agent conveying and cutting mechanism for cutting a film agent between cutters while keeping a rigid shape.

Background

The film agent refers to a film-shaped preparation prepared by processing raw material medicines and proper film-forming materials. Because the membranous preparation has the advantages of wide administration route, uniform distribution of medicines in film forming materials, accurate content, good stability, small volume, light weight and convenient application, carrying and transportation, along with the development of technology, more and more medicines are prepared into the membranous preparation. The formed film agent is subjected to cutting, packaging and other procedures, and the film agent is required to be conveyed; the film is different from the common film material, and has the characteristics of flexibility and softness after being prepared into the film because of containing the drug components, so that the film is not easy to stretch by adopting conveying mechanisms such as a traction roller and the like when the formed film is conveyed, and the content of the drug components of the film after slicing is changed. If the film agent is conveyed by a rear power roller, the film agent is a very soft material and cannot be directly conveyed to a target position. The present inventors have thus discovered a film delivery mechanism that maintains rigidity of the film during delivery while being inflexible, and which has been filed in a different patent application, as will be described below. After the film agent is conveyed by the film agent conveying mechanism, the film agent is required to be transversely cut and then packaged into a box; while the film length of which rigidity is maintained is effective after the film is processed by the film conveying mechanism, the cutting device and the film conveying mechanism also have one end, and thus, it is difficult to maintain the rigidity thereof by the film conveying mechanism alone until it is sent to the cutting device.

Disclosure of Invention

In view of the shortcomings of the background art, the technical problem to be solved by the application is to provide a film conveying and cutting mechanism for conveying and cutting the rigid characters of the film.

Therefore, the application is completed by adopting the following technical scheme: the utility model provides a mechanism is cut in film agent transport, has the frame, be provided with the cutter frame of liftable in the frame, be fixed with down the cutter in the frame, install the cutter on the cutter frame, its characterized in that go up, the film agent entering one side of cutter is equipped with guider down, guider is including the piece baffle that advances that has the epirelief cambered surface, the top of epirelief cambered surface is equipped with the guide pin, the guide pin sets up the symmetry both sides at epirelief cambered surface highest point, and has the clearance that the film agent got into between guide pin and the epirelief cambered surface.

The film feeding device is arranged on the entering side of the feeding guide plate and is provided with a rotatable driving shaft and a driven shaft, the driving shaft and the driven shaft are arranged in parallel, the driving shaft is connected with the driving device, a rotating body with an arc surface is fixed on the driving shaft, an O-shaped ring with a protruding arc surface is sleeved on the driven shaft, and the O-shaped rings are arranged on two symmetrical sides of the highest point of the arc surface of the rotating body.

The upper convex cambered surfaces are uniformly arranged on the sheet feeding guide plate at intervals, and the guide pins are correspondingly and symmetrically arranged above each upper convex cambered surface.

And the discharge ends of the upper and lower cutters are provided with inclined guide plates.

And the driven shaft is provided with a lantern ring, and the O-shaped ring is tightly sleeved on the lantern ring.

According to the structure, after the film passes through the film feeding device, the film has certain rigidity, and then passes between the upper convex cambered surface of the feeding guide plate and the guide pin, the rigid character of the film is kept until the film is conveyed between the upper cutter and the lower cutter to wait for cutting, so that the film material is prevented from being adhered and bent in the conveying process because of softness, viscosity and the like, and cannot enter the upper cutter and the lower cutter to influence cutting, and the film feeding device has a good stable conveying and cutting function.

Detailed Description

Referring to the drawings, the film conveying and cutting mechanism comprises a frame 1, a liftable cutter rest 2 is arranged on the frame 1, a lower cutter 6 is fixed on the frame 1, an upper cutter 5 is arranged on the cutter rest 2, the cutter rest 2 is connected with a driving cylinder 3, a guiding device is arranged on one film entering side of the upper cutter 5 and the lower cutter 6, the guiding device comprises a sheet feeding guide plate 4 with an upper convex cambered surface 9, guide pins 19 are arranged above the upper convex cambered surface 9, the guide pins 10 are arranged on two symmetrical sides of the highest point of the upper convex cambered surface 9, a film entering gap is formed between the guide pins 10 and the upper convex cambered surface 9, the upper convex cambered surface 9 is uniformly arranged on the sheet feeding guide plate 4 at intervals, the guide pins 10 are correspondingly and symmetrically arranged above the upper convex cambered surface 9, a plurality of films can conveniently enter the sheet feeding guide plate 4, and after being input, the films are cut simultaneously, so that the production efficiency of the film feeding guide plate is improved. The film feeding device 7 is arranged on the entering side of the sheet feeding guide plate 4, the film feeding device 7 is provided with a rotatable driving shaft 13 and a rotatable driven shaft 14, the driving shaft 13 is arranged in parallel with the driven shaft 14, the driving shaft 13 is connected with a driving device, a rotating body 17 with an arc surface is fixed on the driving shaft 13, O-shaped rings 16 with protruding arc surfaces are sleeved on the driven shaft 14, the O-shaped rings 16 are arranged on two symmetrical sides of the highest point of the arc surface of the rotating body 17, the number of the rotating bodies 17 is the same as that of the protruding arc surfaces 9, in the embodiment, the number of the protruding arc surfaces 9 and the rotating bodies 17 on the sheet feeding guide plate 4 are five, the rotating bodies 7 are sequentially connected, and after the five rotating bodies 7 are sleeved on the driving shaft 13, positioning rings 19 are fixed on the outer side surfaces of the rotating bodies 17 at the left end and the right end, so that all the rotating bodies 17 are fixed; since the diameter of the driven shaft 14 is much smaller than that of the O-ring 16, a collar 15 is arranged on the driven shaft 16, and the O-ring 16 is tightly sleeved on the collar 15, so that the driven shaft is convenient to replace and install.
