Description

A kind of trimmer

Technical field:

The utility model relates to the trimmer technical field, refers in particular to a kind of trimmer simple, easy to assembly of processing.

Background technology:

Trimmer is in clothing, shoemaking, fields such as handbag are used relatively extensively, see Fig. 1, shown in 2, existing trimmer, it comprises support 01, locking has cover plate 03 on the head 02 of support 01 front end, support 01 downside is fixed with dise knife 06, and dise knife 06 is fixed on the lower shaft 07 of head 02 below, on head 02 front end face, offer upper slitter chute and positioning runner, be arranged with upper cutter head 04 and positioning seat 05 in upper slitter chute and the positioning runner respectively, be fixedly connected with blade on the upper cutter head 04, cover plate 03 is a surface plate, scribble lubricant above, cover plate 03 is locked on the head 02, is used to limit upper cutter head 04 and positioning seat 05.Fig. 3 is the schematic diagram of trimmer, and upper cutter head 04 is connected with eccentric rod 08, and eccentric rod 08 by driven by motor, also is connected with the worm and gear power train by belt pulley on the eccentric rod 08; Dise knife 06 is fixed on the lower shaft 07, is connected with bevel gear on the lower shaft 07, the worm gear of worm and gear power train and bevel gear engagement.Driven by motor eccentric rod 08 rotates, and dise knife 06 rotates with eccentric rod 08, and eccentric rod 08 drives upper cutter head 04 and moves up and down, and shear action is finished in the motion of blade on the upper cutter head 04 and dise knife 06.

The trimmer of said structure, owing to will on head 02, offer upper slitter chute and positioning runner, and head 02 generally is to be linked to be an integral body with support 01, weight is big, external form is irregular, so processing upper slitter chute and positioning runner are very difficult on head 02, processing dimension is difficult for guaranteeing, also is not easy to heat treatment, thereby cause production cost to increase, service life is short.

Summary of the invention:

The purpose of this utility model is to provide a kind of trimmer simple and direct, easy to assembly of processing at the deficiencies in the prior art.

For achieving the above object, the utility model adopts following technical scheme: it comprises support, and the head downside of support front end is equipped with dise knife, and dise knife is fixed on lower shaft the place ahead, the head front the has been fixed with moulding location lid of chute.

Described location covers and forms two chutes, and first upper cutter head chute is built-in with upper cutter head, and another is the positioning seat chute, is built-in with positioning seat.

Described location lid directly is fixed together with head.

Be fixed with front shroud between described location lid and the head.

The utility model adopts head to cooperate the mode of location lid, and cover in the location and to offer upper slitter chute and positioning runner, this structure makes that the processing of trimmer is simpler and more direct, assembling is more convenient, also improved simultaneously the precision of processing, also be convenient to heat treatment, further improved the mechanical performance and the service life of trimmer.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is existing trimmer structural representation;

Fig. 2 is the cover plate schematic diagram of existing trimmer;

Fig. 3 is the fundamental diagram of existing trimmer;

Fig. 4 is the structural representation of location of the present utility model lid;

Fig. 5 is a structural representation of the present utility model;

Fig. 6 is another embodiment schematic diagram of the present utility model.

The specific embodiment:

See accompanying drawing 4,5, the utility model comprises support 10, and head 20 downsides of support 10 front ends are equipped with dise knife 60, and dise knife 60 is fixed on lower shaft 70 the place aheads, and dise knife 60 rotates with the rotation of lower shaft 70.The location lid 30 of chute that has been fixed with moulding in head 20 fronts.

The location cover 30 and head 20 be fixed together, chute is close to head 20.Plastic two chutes on 30 are covered in the location, one of them is a upper cutter head chute 32, be built-in with upper cutter head 40, upper cutter head 40 lower ends are fixed with blade 42, and upper cutter head 40 drives blade and moves up and down along upper slitter chute 32 together, and another is a positioning seat chute 34, be built-in with positioning seat 50, positioning seat 50 lower ends are fixed with spacer 52, but positioning seat 50 up-down adjustment, so that the position of spacer 52 can be fit to the material to be processed of different-thickness.

Usually, upper slitter chute 32 is a vertical direction, and positioning runner 34 is parallel to upper slitter chute 32.

Up-down adjustment positioning seat 50 is so that spacer 52 limits material to be processed, starter motor, the eccentric rod of support 10 inside will drive upper cutter head 40 and move up and down, eccentric rod also will drive lower shaft 70 rotations by worm and gear power train, bevel gear simultaneously, thereby dise knife 60 is rotated, upper cutter head 40 drives blade 42 in the vertical direction high speed reciprocating motions, and blade 42 is finished shear action with the motion of dise knife 60, and unnecessary material is cut off.

In process of production, only need cover and offer upper slitter chute 32 and positioning runner 34 on 30 in the location, 30 volumes are less, weight is lighter because the location is covered, so process very convenient, than on head 20, offering upper slitter chute 32 and a lot of costs of positioning runner 34 savings, and be convenient to heat treatment, and can improve the precision of processing.

See Fig. 6, head 20 and location also can add front shroud 80 between covering 30.

The utlity model has and process advantages such as simple and direct, easy to assembly, also improved the precision of processing simultaneously, thus the mechanical performance and the service life of improving trimmer.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
