Automatic point seam machine
Technical field
The present invention relates to a kind of electric blanket automated production equipments, more particularly, to a kind of automatic point seam machine.
Background technique
The blanket body of electric blanket has two layers of blanket cloth at least, and heating wire coils the inner surface in wherein one layer of blanket cloth, two layers of blanket
Cloth periphery is sewed together, and to prevent two layers of blanket cloth fold separation, some positions also in the middle part of blanket body carry out fixed point sewing.It is existing
The sewing of some fixed points, using worker's fixed point sewing by hand, using with blanket body mould blanket of a size, be provided on mould blanket as a seam
Molding hole, can be to avoid being sewn to heating wire.However due to when sewing needing that mould blanket is layered on blanket cloth and is aligned with blanket cloth, turning
When changing sewing point, mobile blanket cloth is easy to cause mould blanket and blanket cloth to misplace, and artificial sewing efficiency is low, it is difficult to meet standard
Change, the production of scale, it would be highly desirable to improve.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind can be automatic under electric blanket fixed point sewing die cooperation
Complete the automatic point seam machine of electric blanket fixed point sewing.
The technical scheme of the invention to solve the technical problem is: a kind of automatic point seam machine, including band work are flat

The mobile displacement mechanism of mechanism is held, the clamping device, displacement mechanism are electrically connected with the controller of digital control sewing machine respectively.
Preferably, the clamping device includes gear frame, two collets for being fixed on gear frame front end and for controlling
The cylinder A of collet folding, the cylinder A are fixed with gear frame, and the cylinder A is electrically connected with the controller of digital control sewing machine.
Preferably, institute's displacement mechanism includes on workbench and being equipped with the bearing rod of longitudinally guiding mechanism, pushing away
Bar, the cylinder B being connect by the support of bearing with bearing rod and the cylinder C for controlling the rotation of cylinder B push rod;The gear frame with
Bearing rod is slidably connected, and the push rod is equipped with the friction pulley for controlling gear frame transverse shifting, sets above the gear frame
There is the pinch roller of friction pulley matching sum, the axis of the pinch roller is connect with the support of bearing;The cylinder B and cylinder C is stitched with numerical control respectively
Thread machine controller electrical connection.
Compared with the prior art, the advantages of the present invention are as follows based on digital control sewing machine, expand workbench, in platform
On add clamping device for clamping electric blanket fixed point sewing die and the mobile displacement mechanism of control clamping device, and make to press from both sides
It holds mechanism and displacement mechanism to be electrically connected with the controller of digital control sewing machine respectively, thus in electric blanket fixed point sewing die with cooperation
With the lower fixed point sewing that can be automatically performed to electric blanket, improves work efficiency, reach the production of standardization, scale.
As an improvement, the gear frame includes the hack lever and and friction pulley being slidably matched by sliding slot with raised line on bearing rod
And the drive rod of pinch roller cooperation, the drive rod and the removable connection of hack lever.The permanent friction of friction pulley and pinch roller will lead to biography
Lever abrasion, the drive rod needs after abrasion are replaced in time.
Preferably, the section of the raised line is trapezoidal or arc-shaped.
Preferably, the cylinder B is fixed on the back of digital control sewing machine rack, the push rod of the cylinder B passes through numerical control
It is connect after sewing machine frame with bearing rod;Make device structure compact and reasonable.
As an improvement, the front bottom end of the workbench is equipped with control switch, the control switch and digital control sewing machine
Controller electrical connection, facilitate worker's commanding apparatus.
Detailed description of the invention
Fig. 1 is schematic perspective view of the invention.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
This preferred embodiment is a kind of automatic point seam machine as shown in Figure 1, including the digital control sewing machine 1 with workbench 11,
And it is located at the clamping device on workbench 11 for clamping electric blanket fixed point sewing die and controls clamping device movement
Displacement mechanism, clamping device, displacement mechanism are electrically connected with the controller 12 of digital control sewing machine 1 respectively.
Wherein, clamping device includes gear frame, two collets 23 being fixed on gear frame front end (only show one in Fig. 1
Collet 23, another collet 23 are blocked, are not shown) and for control collet 23 folding two cylinder A24, cylinder A24 with
Gear frame is fixed, and cylinder A24 is electrically connected with the controller 12 of digital control sewing machine 1.Collet 23 and cylinder A24 can also use finger cylinder
Replacement.
Displacement mechanism includes on workbench 11 and being equipped with the bearing rod 31 of longitudinally guiding mechanism, push rod 331, passing through
The cylinder B33 that the support of bearing 32 is connect with bearing rod 31 and the cylinder C for controlling the rotation of cylinder B33 push rod 331 (do not show in figure
Out, it is arranged below 1 frame seat of digital control sewing machine);Gear frame is slidably connected with bearing rod 31, and push rod 331 is equipped with for controlling
The friction pulley (not shown) of gear frame transverse shifting processed, gear frame top are equipped with the pinch roller 34 of friction pulley matching sum, pinch roller
34 axis is connect with the support of bearing 32;Cylinder B33 and cylinder C is electrically connected with the controller 12 of digital control sewing machine 1 respectively.
As an improvement, gear frame includes the hack lever 21 and and friction pulley being slidably matched by sliding slot with raised line on bearing rod 31
And the drive rod 22 of pinch roller cooperation, drive rod 22 and the removable connection of hack lever 21.On bearing rod 31 section of raised line be it is trapezoidal or
It is arc-shaped.
In the present embodiment, cylinder B33 is fixed on the back of 1 rack of digital control sewing machine, and the push rod 331 of cylinder B33 passes through
