Description

Technical Field

[0001] The utility model relates to the technical field of button sewing machines, in particular to a cloth tape button sewing machine. Background Art

[0002] The button sewing machine is a special automatic sewing machine that can complete the sewing of regular-shaped buttons and operations with "nailing and dropping" sewing techniques, such as sewing trademarks, labels, caps, etc. The most commonly used are disc-shaped two-hole or four-hole (also known as flat buttons) buttons. By replacing various special button sewing machine accessories, a button sewing machine can sew various types of buttons such as shank buttons, metal buttons, mother-and-child buttons, foot-wrapped buttons, and discipline buttons. Users can ask the equipment supplier to provide special accessories for the button sewing machine according to their needs.

[0003] In daily life, after the quilt core is put into the quilt cover, the quilt core often moves inside the quilt cover. Therefore, a cloth belt with buttons (the buttons are mother-and-child buckles) is used to fix the quilt core and the quilt cover. When producing this cloth belt, the whole cloth belt is first transported to the button sewing station through the tensioning mechanism on the button sewing machine, and then the button sewing machine uses the punching needle and the punching table to form a clamping force on the cloth belt to punch out the holes for button installation, and then the buttons in the material tray are pushed to the pressing nail column by the feeding trough and the pushing mechanism, and then the pressing nail column pushes the button sub The button moves to the hole position of the cloth tape, and then the mother button is transported to the top of the child button by another feed trough, and then the mother button is pressed downward by the push rod to complete the assembly of the child button and the mother button. Since the buttons on the cloth tape are arranged equidistantly, when the existing button sewing machine is working, after the first button is sewn on the cloth tape, it is necessary to manually pull the cloth tape to move a distance before sewing the second button. However, this movement method is subject to many human factors, and the spacing and sewing efficiency of the buttons cannot be guaranteed. At the same time, an additional labor force is required, which will increase the cost of sewing the buttons.

[0004] Therefore, there is an urgent need for a button sewing machine that can replace manual movement of cloth tape to improve the efficiency of button sewing, ensure the spacing of buttons and reduce the cost of button sewing. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a cloth tape button sewing machine, which is used to solve the problem that the existing button sewing method requires manual pulling of the cloth tape to move, and thus cannot ensure the spacing of the buttons and the button sewing efficiency.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] The cloth button sewing machine comprises a sewing unit and a moving unit, wherein the sewing unit is provided with a frame, a machine head is provided above the frame, a slide rail is provided in parallel on the frame, a slide plate is slidably provided on the slide rail, a punching platform and a nail pressing column are provided on the slide plate, and a material tray is also provided on the frame, a material feeding trough is provided at the discharge end of the material tray, a pushing cylinder is provided at the end of the feeding trough away from the material tray, a pushing plate is provided at the output end of the pushing cylinder, a punching needle and a push rod are provided on the machine head, the moving unit comprises two parallel vertical plates, a slide plate is detachably installed between the two vertical plates, a clamping opening is opened on the slide plate along the length direction, a first clamping cylinder is installed on one side of the vertical plate close to the sewing unit, a lead screw is provided between the two vertical plates, a driving motor is provided at one end of the lead screw, a second clamping cylinder is provided on the lead screw, and clamping claws are symmetrically provided at the output ends of the first clamping cylinder and the second clamping cylinder, and the first clamping cylinder and the second clamping cylinder act alternately.

[0008] Furthermore, the second clamping cylinder is provided with an anti-rotation mechanism.

[0009] Furthermore, the anti-rotation mechanism includes a guide rail arranged on one side of the slide plate close to the second clamping cylinder, and a slider is provided at a position of the second clamping cylinder corresponding to the guide rail, and the slider cooperates with the guide rail.

[0010] Furthermore, guide plates are respectively provided on both sides of the slide plate at the clamping opening, and the spacing between the guide plates is greater than the width of the cloth belt.

[0011] Furthermore, receiving portions are left on both sides of the slide plate at the clamping opening.

[0012] In summary, the beneficial technical effects of the utility model are:

[0013] (1) The first clamping cylinder can fix the tape through the clamping claw when sewing buttons to prevent the displacement of the tape from causing misalignment between the hole and the button. At the same time, the driving motor drives the lead screw to make the second clamping cylinder clamp the tape and move it equidistantly, thereby achieving precise and equal-length movement of the tape and ensuring the spacing of the buttons. In addition, the second clamping cylinder replaces manual pulling of the tape, which not only saves labor and reduces the cost of sewing buttons, but also avoids human factors and improves the efficiency of sewing buttons.

[0014] (2) By opening a clamping opening on the slide plate, the symmetrically arranged clamping claws can clamp both sides of the fabric belt, which is more conducive to the movement of the fabric belt by the second clamping cylinder.

[0015] (3) The receiving part on the slide can provide a certain support to the cloth belt, and at the same time, the guide plate can improve the directionality of the cloth belt during movement and prevent the cloth belt from sagging. BRIEF DESCRIPTION OF THE DRAWINGS
