In order to guarantee that synchronous drive mechanism is simple, it is convenient to control, preferred technical scheme is, described synchronous drive mechanism comprises synchronous motor, described synchronous motor is fixedly installed on described depression bar side, described roller is that side is provided with the gear teeth, and the gear teeth of described roller match with the gear teeth of travelling gear, and described travelling gear is connected with the output of synchronous motor by power transmission shaft.
Waist of trousers thickness is because selecting the difference of material to differ, the roller of level altitude cannot be applicable to the waist of trousers sewing operation of variable thickness, for roller top is pressed on dress material, guarantee the frictional force between roller and dress material, and then the tractive force of assurance pair of rollers dress material, preferred technical scheme is that described depression bar top is equipped with depression bar manual lifting mechanism.
In order to simplify the structure of roller press, preferred technical scheme is, described depression bar manual lifting mechanism comprises and is arranged on the vertical substrate in described depression bar side, described substrate is fixedly connected with Sewing machines, described substrate is fixedly connected with the top of guide post by connector, the top of described depression bar is provided with described pressure shaft to consistent blind hole, the bottom of described guide post is equipped with in described blind hole, described guide post is arranged with extension spring outward, the two ends of described extension spring are connected with depression bar end face with connector respectively, described depression bar side is fixedly installed elevator, described elevator upper end is equipped with the spanner that one end is cam, bearing pin on the center of described cam and described substrate is connected.
The material of roller mostly is metal, and for fear of metal surface and independently produce relative displacement between rubber antiskid layer, preferred technical scheme is that described rubber antiskid layer heat of vulcanization is pressed on the wheel face of described roller.
In order to guarantee roller, synchronize and rotate with rubber antiskid layer, preferred technical scheme can also be, on the wheel face of described roller, be provided with several grooves, the inner ring surface of described rubber antiskid layer is provided with raised line, and described groove matches with the raised line of described rubber antiskid layer inner ring surface.
Advantage of the present utility model and beneficial effect are:
This waist of trousers Sewing machines roller press is simple in structure, roller by employing with rubber antiskid layer, roller top is pressed on dress material, guarantee frictional force certain between the rubber antiskid surface of roller and dress material, when roller rolls, dress material is applied to tractive force, drive the synchronous charging of dress material, guarantee that dress material charging rate and Sewing needles stop over evenly, contribute to increase work efficiency.
