Abstract

The utility model relates to the technical field of sewing machine equipment, in particular to a speed regulator with compact structure for an industrial sewing machine. The speed regulator with compact structure for an in industrial sewing machine aims at solving the problems of inconvenient transportation and installation, easy occurrence of faults and high cost in the prior art. In order to solve the problems in the prior art, the speed regulator with compact structure for the industrial sewing machine adopts the following technical scheme: the speed regulator comprises a fixed tank body with a sleeve and a crank and is characterized in that the sleeve is provided with a torsion spring, the end part of the torsion spring is pressed on the crank, an upper limit block and a lower limit block are arranged at the outer side of the fixed tank body, and the motion stroke of the crank is clamped between the upper limit block and the lower limit block. Compared with the prior art, the speed regulator has the advantages of being convenient for transportation and installation, low in fault rate, easier for realizing an all-in-one machine and low in cost.

Description

A kind of industrial sewing machine speed regulator of compact conformation
Technical field
The utility model relates to the Sewing machines equipment technical field, is specifically related to a kind of industrial sewing machine speed regulator of compact conformation.
Background technology
Use in sewing machine speed regulator now generally all comprises sleeved static housing is set, and static housing is provided with crank, and the static housing arranged outside has extension spring as the crank return unit, and extension spring one end is fixed on the static housing, and the other end connects with crank.During work, crank axle action drives crank-motion, and extension spring pulls crank it is resetted when arriving desired location.Because present speed regulator volume is bigger, all be therefore as stand-alone assembly, after being transported to the place, be installed on again on the special installing rack that is provided with in platen bottom, the interface that is provided with on the circuit board with speed regulator is connected with control system external circuit plate again.The problem that prior art exists is: (1) transportation is installed inconvenient: speed regulator conduct independently parts is transported and packed, and also needs to install connection at the scene, and is therefore very inconvenient; (2) easy break-down: therefore control system and speed regulator connecting line externally are vulnerable to the collision influence in the external world and cause the connection fault, influence work; (3) cost height: both connect the long circuit of needs, and the manufacturing cost of speed regulator itself is higher, transport and installation cost in addition, and therefore whole cost is higher.
Summary of the invention
The purpose of this utility model provides a kind of industrial sewing machine of compact conformation, to solve transportation installation inconvenience, easy break-down and the high problem of cost that prior art exists.
For achieving the above object, the technical scheme that the utility model provides is:
A kind of industrial sewing machine speed regulator of compact conformation, comprise sleeved static housing and crank are set, its special character is: described sleeve is provided with torsion spring, the end of torsion spring is pressed and is located on the crank, the static housing arranged outside has upper limit position block and lower position block, and the movement travel of crank is located between upper limit position block and the lower position block.
Be provided with control circuit board in the said fixing casing.
Compared with prior art, the utlity model has following advantage:
1, easy transportation and installation: substituted extension spring with torsion spring in the utility model, compact overall structure, volume reduces, and therefore transportation is installed more convenient.
2, fault rate is low: control circuit board is arranged in the static housing, and the circuit of having avoided collision, factor such as artificial to cause connects not smooth.
3, all-in-one realize easier: less because of its volume, therefore the speed regulator static housing can be directly fixed on the idle position of head, two independently parts integrate, control circuit board directly is connected with the interior master control case of head by line.Complete machine structure is compact more like this, has reduced the packing and the installation of parts during transportation, and control circuit board directly is connected with motor simultaneously, and the switching link in the middle of having reduced has been avoided the fault generation.
4, reduce cost: no matter be independently to use or as the part of all-in-one, its designs simplification all, has reduced the cost of raw material, cost of transportation is descended, as all-in-one the time, more reduced installation workload, therefore can effectively reduce cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view of Fig. 1;
Fig. 3 is a scheme of installation of the present utility model.
Description of reference numerals is as follows:
The 1-lower position block, 2-upper limit position block, 3-static housing, 4-torsion spring, 5-crank, 6-control circuit board, 7-head.
The specific embodiment
Do detailed description below in conjunction with the accompanying drawing utility model.
Referring to Fig. 1 and Fig. 2.A kind of industrial sewing machine speed regulator of compact conformation comprises the static housing 3 and the crank 5 that are provided with sleeve 8, and the rotating shaft of crank 5 is inserted in the sleeve 8.Said sleeve 8 is provided with torsion spring 4, and the end of torsion spring 4 is pressed and is located on the crank 5.Said static housing 3 arranged outside have upper limit position block 2 and lower position block 1, and the movement travel of crank 5 is located between upper limit position block 2 and the lower position block 1.Be provided with control circuit board 6 in the said static housing 3.
When crank 5 actions, it moves between upper limit position block 2 and lower position block 1, before not working, crank 5 is leaned against on the upper limit position block 2 by torsion spring 4 counterclockwise active forces, crank 5 is subjected to clockwise pulling force to move to lower position block 1 during work, cancel working pulling force when quitting work crank 5 be subjected to torsion spring 4 counterclockwise active forces to get back to upper limit position block 2, finish a working cycles.
Static housing can be installed in any part that designs on the industrial sewing machine.
Referring to Fig. 3, the static housing in the utility model 3 is fixed in the head rear side, whole speed regulator with combine together after head is connected.
