Background technology
At present, the automatic thread trimming device of industrial sewing machine normally to be matched trimming by moving knife, stationary knife, wherein moving knife drives moving knife knife rest by lower shaft and transmission mechanism, and moving knife knife rest drives the displacement of moving knife, is namely drive moving knife by lower shaft in brief, this structure is often because lower shaft is different from the rotating speed of upper axle, so be provided with Compulsory reduction mechanism adjustment, but still there is the striker phenomenon of certain probability, add mechanism element simultaneously, increase cost, also make noise too increase.In order to improve plant produced efficiency, reduce workman workload, ensure the continuity of operation, most industrial sewing machine all adds automatic thread trimming device, to reach laborsaving, power saving, less manpower.
Number of patent application 201210204131.2 it comprise moving knife, stationary knife, connecting rod and the trimming electromagnet that can cooperatively interact and cut off line, stationary knife is fixed on Sewing machines support, one end of moving knife and connecting rod is fixed on trimming knife rest, trimming knife rest is sleeved on lower shaft, the other end of connecting rod and one end of drive link hinged, the other end of drive link is connected with the dynamic iron of trimming electromagnet, feed lifting rock shaft is provided with trimming cam, trimming cam is positioned at the side of drive link, drive link is fixed with the straight pin driving drive link movement with trimming cam engagement.It utilizes during electromagnetic actuation and provides power, utilizes linkage that moving knife is matched with stationary knife and carries out automatic shearing, and is resetted by the twisting resistance of the compression stress of the back-moving spring on linkage and linkage when electromagnet power-off restoration.But, above-mentioned automatic thread severing device of sewing machine is when the compression stress torsional moment that is comparatively large or linkage of back-moving spring is larger, the phenomenon that adhesive is slow and cause the trimming reaction speed of device slow is there is with regard to easily making electromagnet, even there will be electromagnet time serious cannot adhesive and cause the situation that cutting facility cannot normally work, and checking have impact on the service behaviour of device.Number of patent application: 201220289478.7 disclose a kind of automatic thread severing device of sewing machine, comprising to cooperatively interact cuts off the moving knife of line, stationary knife, connecting rod and trimming electromagnet, stationary knife is fixed on Sewing machines support, one end of moving knife and connecting rod is fixed on trimming knife rest, trimming knife rest is sleeved on lower shaft, the other end of connecting rod and one end of drive link hinged, the other end of drive link is connected with the dynamic iron of trimming electromagnet, feed lifting rock shaft is provided with trimming cam, trimming cam is positioned at the side of drive link, drive link is fixed with the straight pin driving drive link movement with trimming cam engagement.Number of patent application: 201320523393.5 wire shearing driving devices disclosing a kind of Sewing machines, the linkage comprising cutting knife and be connected with cutting knife, this drive unit and linkage are connected and it drives cutting knife action by linkage, this device also comprises a cylinder and guide cylinder, described guide cylinder is connected on the casing of Sewing machines, the piston rod portion of above-mentioned cylinder is in guide cylinder and be provided with spring between piston rod and guide cylinder, and above-mentioned linkage and described piston rod are connected.Above-mentioned patent structure is complicated, is arranged on Sewing machines upper volume larger.The striker problem of Sewing machines industry automatic thread trimming device urgently to be resolved hurrily, to ensure that sewing work process is smooth, improves trimming precision and ensure that production efficiency.
Summary of the invention
The present invention is to overcome deficiency of the prior art, provides a kind of industrial sewing machine side draught cutting facility, it solve in prior art produce the work that striker phenomenon causes discontinuous, affect the problems such as production efficiency.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of industrial sewing machine side draught cutting facility, it is characterized in that: comprise side draught device body, support plate, Thread odds suction pipe, fuel sucking pipe, moving knife, stationary knife, control lever, triangle fixed block, semicircle fixed block, described fuel sucking pipe and the affixed integrally structure of Thread odds suction pipe, described Thread odds suction pipe, fuel sucking pipe and the affixed integrant side draught device body of support plate, described stationary knife and support plate affixed, described moving knife and control lever affixed formation movable knife linkage, described control lever and axle sleeve are slidably connected, described axle sleeve is connected with support.
Described support plate is provided with two circular hole elongated slots at same axis.
Described fuel sucking pipe two ends upwarp into obtuse angle, and its shape is U-shaped.
Side and the position, support front end of described movable knife linkage and stationary knife are connected with cover plate.
Beneficial effect: the present invention compared with prior art, has that trimming precision is high, easy and simple to handle, advantages of simple structure and simple.The work that this device is avoided striker phenomenon and caused is discontinuous, affect the problems such as production efficiency.
