Rigid epaulet apparatus for sewing
Technical field
The utility model relates in field of textiles, in particular to dress and personal adornment processing equipment field, relates in particular to a kind of rigid epaulet apparatus for sewing.
Background technology
In uniform dress ornament, having rigid epaulet, is on hard epaulet base plate, to cover the fabrics such as ribbon cloth, base fabric to make.The ribbon cloth covering, base fabric etc. are combined with base plate in the mode of sewing.Rigid epaulet base plate is in the past plane, and new-type rigid epaulet base plate is cambered surface, more attractive in appearance on clothes like this.But traditional stitch machine is all plane sewing, be not also applicable at present the Sewing machines that cambered surface is made.With plane stitching sewing machine cambered surface thing, can affect the attractive in appearance of upper and lower stitching.In addition, the sideline of epaulet is pentagon, keep the skilled sewing technology of uniformity needs of back gauge, and many at present by manual operations, sewing speed is low, and homogeneity of product is poor.
Sewing machines is actual can be decomposed into two parts, and one is sewing mechanism, and usually said Sewing machines " head ", completes acupuncture and bottom line, face cabling; Another part is the travel mechanism of workpiece, and distance mobile between every two pins is " needle gage ", and a plurality of continuous needle gages form stitching, is also seam mark.The travel mechanism of tradition Sewing machines has been coordinated with " feed dog " below workpiece by " presser feet " above workpiece, can only realize the linear displacement of one dimension.If make curve, need be by manually workpiece being applied to the extra power that is displaced sideways.
Computer embroidery machine is a kind of Novel intelligent stitch machine, and actual is that this planar movement mechanism can, in the certain limit of workpiece two dimensional surface, move freely in X-direction, Y-direction by the planar movement mechanism of a computer control and the coupling apparatus of head.The travel mechanism that this computer is controlled can form the needle gage on any direction, also can change needle gage size, particularly can weave in advance the sewing program of making figure, after placing workpiece, by computerized high-speed, is automatically completed.But the travel mechanism of computer embroidery machine is planar mechanism, the workpiece that is applicable to making is also plane, and the pattern of making is also planar graph, is not suitable for the workpiece processing of arc-shaped curved surface.
Utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of rigid epaulet apparatus for sewing is provided, the technical problem of the rigid epaulet of solution curved plate in automatic sewing processing.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of rigid epaulet apparatus for sewing, by head of sewing machine and the travel mechanism that is positioned at the first side of described sewing machine, formed, the compound displacement mechanism of the cylinder solid space that the described Wei Yi of the travel mechanism linear displacement Ji Yi of mechanism angular displacement mechanism forms, described head of sewing machine and described travel mechanism, by computer control, complete the processing made from arc-shaped curved surface workpiece thus.
Further, described travel mechanism is connected by the first motor and drives the first Timing Belt, on described the first Timing Belt, be fixed with a support, support is movably connected in pair of guide rails, the second motor and wheel frame are installed on described support, described the second motor is realized angular displacement by the second Timing Belt driving wheel frame rotation, and piece-holder is taken turns on frame described.
Preferably, the belt wheel at described the first Timing Belt two ends is fixed between described guide rail.
Further, described travel mechanism is connected by the first motor and drives a screw mandrel, described screw mandrel is connected with a support by feed screw nut, described support is connected at least one guide rod be arrangeding in parallel with screw mandrel, the second motor and wheel frame are installed on support, described the second motor is realized angular displacement by the second Timing Belt driving wheel frame rotation, and piece-holder is taken turns on frame described.
Further, described the first motor, the second motor are stepper motor or AC servo motor.
The beneficial effects of the utility model are:
Rigid epaulet apparatus for sewing described in the utility model, completely by computer control.Epaulet has the specification varying in size, and it makes stitching difference, can work out in advance and debug sewing program, and preserve sewing program.When producing, only need call corresponding program high-speed production immediately.The human factor of thoroughly having got rid of operative employee, product quality is high, and yield rate is high, high conformity, high-speed and high-efficiency.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
