Description

A kind of cutter frame structure of three swing rods driving

Technical field

The utility model relates to a kind of cutter frame structures of three swing rods driving.

Background technique

Vertical-type packing machine currently on the market mostly uses gear & rack structure, and principle is that gear rotation drives left and right Two sides rack gear do above and below move toward one another, operation in noise it is big, long-play rack gear serious wear, at the same because rack gear assemble Difficulty also easily adjusts without positive and negative thread and then causes difficulty after sale.

Summary of the invention

The utility model makes improvement for the above-mentioned problems of the prior art, i.e., skill to be solved in the utility model Art problem is to provide a kind of cutter frame structure of three swing rods driving, and structure is simple, and assembly is easy, and noise is small, easy to use.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of cutter frame structure of three swing rods driving, Including rack, erectting in the rack has more guide rods, is provided with the upper slitter moved up and down along guide rod on the guide rod Frame and lower slide；The front end of rack bottom is hinged with the main shaft that rotation is driven by driving mechanism, and rear end of rack bottom is hinged There is driven shaft, a connecting rod is hinged between the main shaft and driven shaft, to realize the synchronous rotation of the two main shaft and driven shaft, institute The one end at the both ends and driven shaft of stating main shaft is installed with a swing arm, and a long axis and a short axle are hinged in the swing arm, described Long axis upper end is hinged with upper tool post, and short axle upper end is hinged with lower slide.

Further, the linear bearing being arranged on the guide bar is provided on the upper tool post and lower slide.

Further, the driving mechanism is cylinder or servo motor.

Further, the middle part of the main shaft and driven shaft is also installed with swing arm, the output end of the driving mechanism with Swing arm is hinged in the middle part of main shaft.

Further, several lever arms, the connecting rod, long axis are hinged on the swing arm, upper tool post and lower slide It is screwed on corresponding lever arm end respectively with the end of short axle.

Further, the thread of the connecting rod, long axis and short axle both ends is mutually reversed.

Further, the long axis in same swing arm and short axle are located on the different end faces of swing arm.

Further, hot knife is provided at the top of the bottom of the upper tool post and lower slide.

Compared with prior art, the utility model has the following beneficial effects:

1, connecting rod, long axis and short axle are positive and negative tooth, easy to adjust, mute compared with the rack gear of market, easy to adjust, it is easier to Assembly；

2, the design of three swing rods drive upper lower slide do it is reciprocal move toward one another, it is stable, easily assemble, noise is small；

3, main driven shaft is driven, adjusting side using adjustable positive and negative thread mechanical linkage connection instead of conventional synchronization wheel, sprocket wheel Just, noise is small, and assembly is easy, and replacement is quick.

The utility model is described in more detail with reference to the accompanying drawings and detailed description.

Detailed description of the invention

Fig. 1 is the construction schematic isometric of the utility model embodiment.

Fig. 2 is the construction schematic front view of the utility model embodiment.

In figure: 1- rack, 11- guide rod, 2- upper tool post, 21- hot knife, 3- lower slide, 31- linear bearing, 4- main shaft, 5- driven shaft, 6- connecting rod, 7- swing arm, 71- long axis, 72- short axle, 8- lever arm.

Specific embodiment

Embodiment one: as shown in Fig. 1~2, a kind of cutter frame structure of three swing rod driving, including rack 1 is erected in the rack It is vertical to have more guide rods 11, the upper tool post 2 and lower slide 3 moved up and down along guide rod is provided on the guide rod；The machine Frame front bottom end is hinged with the main shaft 4 that rotation is driven by driving mechanism, and rear end of rack bottom is hinged with driven shaft 5, the master A connecting rod 6 is hinged between axis and driven shaft, with realize both main shaft and driven shaft synchronous rotation, the both ends of the main shaft and One end of driven shaft is installed with a swing arm 7, is hinged with a long axis 71 and a short axle 72 in the swing arm, the long axis upper end with Upper tool post is hinged, and short axle upper end is hinged with lower slide.

In the present embodiment, the linear bearing 31 being arranged on the guide bar is provided on the upper tool post and lower slide.

In the present embodiment, the driving mechanism is cylinder or servo motor.

In the present embodiment, the middle part of the main shaft and driven shaft is also installed with swing arm, the output end of the driving mechanism It is hinged with swing arm in the middle part of main shaft.

Several lever arms 8, the connecting rod, length are hinged in the present embodiment, on the swing arm, upper tool post and lower slide The end of axis and short axle is screwed onto respectively on corresponding lever arm end.

In the present embodiment, the thread of the connecting rod, long axis and short axle both ends is mutually reversed.

In the present embodiment, long axis and short axle in same swing arm are located on the different end faces of swing arm.

In the present embodiment, hot knife 21 is provided at the top of the bottom of the upper tool post and lower slide.

By the main axis that drives of driving mechanism, main shaft drives driven shaft to rotate by connecting rod, then passes through long axis respectively It is moved toward one another with the upper and lower knife rest of short axle drive or counter motion, whole service process noise is small；The end of connecting rod, long axis and short axle Portion is respectively provided with reversed thread, in this way in swivel link, long axis and short axle and the angle of adjustable rotation and upper and lower knife The stroke of frame.

The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the patents it is equal Deng variation and modification, it should all belong to the covering scope of the utility model.
