Abstract

Automatic film slitter is mounted to fresh keeping film box for slitting fresh keeping film. It consists of rubber band in proper thickness and length, blade in proper tilt angle, part of iron sheet in proper thickness and block of proper material. The present invention has the technological feature that the blade moves linearly along the rack to slit the film.

Description

Automatic film slitter

This technical field that the present invention belongs to: plastic cement five metals field.

This invention is to tear it in person always not down when once using common preservative film, finger also allows saw blade on the preservative film box give and has cut out blood at last, because it is current unexpected, I am determined to design a kind of preservative film cutter of safe and convenient use, finally associate the aircraft catapult on the United States aircraft carrier, imagination, if the draw bar on the ejector has become one cutter, this has how rods to allow it cut object so! So just found out automatic film slitter.

The purpose of invention automatic film slitter is to provide convenience and security protection for the preservative film user.

This invention is to go up at the cast guide rail (Fig. 3) that an iron sheet is done a plastic slide block (Fig. 4) with rubber band (Figure 10) traction is installed, the blade of tiltedly putting (Fig. 4 D) is housed on the slide block, when slide block be pulled to guide rail of button (Fig. 1 C) is housed the time, slide block can be pinned by button, and rubber band also is elongated simultaneously, and slide block has gathered potential energy.At this moment press button, slide block will be unlocked, potential energy is released, and blade is that (Fig. 1 D) cuts to the preservative film above the guide rail along with slide block body (Fig. 4 B) travels forward along guide rail together, the automatic film slitter simple structure, be made up of five parts altogether, all parts that can not decompose again also just have 11, and material all is modal, part production is easy, and it is also easy to assemble.

Than the saw blade on the existing preservative film box, automatic film slitter uses with pine safety again freely, does not worry incised wound.In addition, compare with just listing a kind of film slitter soon, automatic film slitter can be contained on the preservative film box, and it can come together and come along (throwing away) with box, and the former volume is big and heavy, definitely is unable to handle.The cost that is exactly this film slitter in addition is too high, is several times of price of a box preservative film, has only the only a few people to be willing to buy, but also reinstalls in the film slitter and could use after will splitting out the preservative film circle in the box, and is very bothersome.

Fig. 1 is the integral body of automatic film slitter and Wrapping case combination, the guide rail of automatic film slitter is bonded at above the preservative film box with viscose glue, because preservative film can only be cut in the stroke of blade, so, carton and guide rail will be grown the width of preservative film, and (Figure 1A to B) is the segment length that carton is longer than preservative film.

(Fig. 2) be the enlarged drawing of automatic film slitter, it is made up of guide rail (Fig. 3), slide block (Fig. 4), button (Fig. 8), running roller (Fig. 9), these five parts of rubber band (Figure 10).

(Fig. 3) be the part of automatic film slitter: guide rail, 4 holes are arranged above it, be respectively (Fig. 3 A), (Fig. 3 B), (Fig. 3 C), (Fig. 3 D).The effect of (Fig. 3 A) is to pass through rubber band; The effect of (Fig. 3 B) is a dress push button shaft (Fig. 8 D); (Fig. 3 C) respectively washing the hole that the square sheet of the guide rail side of still ining succession, square sheet plate stay after straight open on two sides of guide rail.The effect of side's sheet is to stop slide block; (Fig. 3 D) is the axle usefulness of dress rubber band wheel (Fig. 9 A).

(Fig. 4) be the slide block assembly, it is made up of (Fig. 4 A, B, C, D, E).(Fig. 4 A) is that hand is dialled, and is the cuboid that plastics form, and it links by blade (Fig. 4 D) and slide block body (Fig. 4 B), and its effect is to stir slide block to the operator; (Fig. 4 B) is the slide block body, also is the cuboid that plastics form, and its effect is to link each parts and sliding ground in guide rail; (Fig. 4 C) is that a pin falls one jiao rectangle iron plate, sees (Fig. 5) for details, and effect is to hook button; (Fig. 4 D) is diamond shaped insert, and (Fig. 6) its effect that sees for details is the cutting preservative film and plays connector and dial (Fig. 4 A) and slide block (Fig. 4 B) two upper-parts; (Fig. 5) hole on the iron plate and (Fig. 6) two holes on the blade are to play fixing effect after they are injected into plastic body.(Fig. 4 E) is a little aluminum pipe, sees (Fig. 7) for details, and its effect is that slide block and rubber band are connected, and specific practice is to allow one of little aluminum pipe to annotate in advance on one's body slide block, and the outside is stayed in the other end, waits rubber band to insert the back and gets final product with tool holder.See (Figure 11 D).

(Fig. 8) be button, it is a pentahedron that is converted into by the hexagon iron plate, upwards a front end has a circular hole, the effect of (Fig. 8 A) circular hole is the hook (Fig. 4 C) that fastens slider tail, there are three square frames (Fig. 8 B) the circular hole back, and iron plate (seeing a Fig. 8 C) end of going out from the square frame button of still ining succession is when of the rubber band that comes is put on when inserting three square frames with the iron plate centre in the hole (seeing Fig. 3 A) of button below, iron plate is pressed to square frame, just can clamp one of rubber band.See (Fig. 2 A) for details.

Being the rubber band running roller (Fig. 9), is the running roller that has groove made of plastic, and effect is to allow the long length in rubber band court of a feudal ruler in the confined space, makes rubber band all guarantee enough elastic force in the whole stroke of traction sliding block motion.

(Figure 10) be rubber band, it is to justify bar shaped, and effect is to produce pulling force, draws the slide block acting well.

(Figure 11) be the work principle of automatic film slitter.At first an end of rubber band (Figure 11 A) is an end of button leave behind (Figure 11 K), when pinching hand, user's hand dials (Figure 11 C) when shifting the end onto backward, hook on the slide block (Figure 11 B) just backs down button backward, when cleek enters the circular hole (seeing Fig. 8 A) of button one end, slide block will be fastened, at this moment whole piece rubber band (Figure 11 A to D) is drawn to such an extent that more elastic force has been arranged, if cut preservative film, as long as hold the forward position (Fig. 1 D) of preservative film on the other hand, one holds an end of Wrapping case and presses button (Figure 11 J), button will be opened to the state of (Figure 11 H), the slide block dropout is being drawn by rubber band and is being travelled forward, blade on the slide block (Figure 11 I) just cuts horizontal preservative film on guide rail along guide rail, up to having cut by obstruction side's sheet till (Figure 11 E) block.

Owing to will allow rubber band that enough length is arranged, rubber band has one section (Figure 11 F to G) and running roller black part (Figure 11 F) will put in the letter preservative film box.

After this commercialize invention, can develop towards two aspects: be the disposable product of development on the one hand, promptly automatic film slitter and Wrapping case two-in-one are used, and throw away together after using up.Be the environmental and durable type of exploitation on the other hand, promptly the preservative film sylphon cuts away and stays automatic film slitter, and respectively there is the interface of simple assembly and disassembling at this position that just requires Wrapping case and automatic film slitter to link.

Claims

The technical characterictic of automatic film slitter is: 1, its blade is to do rectilinear motion along guide rail;
2, it is to utilize the elastic force execution.
