Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to an automatic folding sewing machine with a tail. Background Technology

[0002] A sewing machine is an industrial and household tool that uses sewing thread to sew fabric or other materials together. Its core components are: the sewing head, needle and thread spool, presser foot and feed mechanism, and base. The sewing head contains a motor and transmission system that drives the needle, threading it to form a stitch. The thread spool stores the thread, the presser foot holds the fabric, the feed mechanism controls the fabric's movement speed, and the base supports the entire machine. As the needle moves up and down, the thread hook mechanism interweaves the bobbin thread and top thread to form a stitch. The electric motor drives the conveyor belt, and the speed is controlled by a pedal or button to achieve continuous sewing.

[0003] In sewing machine production, there are processing operations that require hemming the fabric before sewing. Existing sewing equipment is mostly a single sewing device, and in actual production, hemming often requires manual assistance, which is time-consuming, labor-intensive, and lacks standardization. Therefore, we designed an automatic folding sewing machine with a tail to solve these problems. Utility Model Content

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This automatic belt tail folding sewing machine places the belt tail through the guide table onto the folding plate and take-up roller, so that the pressure bar presses on the belt tail to fix it. The horizontal movement of the support platform allows the end of the belt tail to fold around the pressure bar, and the downward movement of the folding plate can press down and fix the end of the belt tail to complete the folding.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 The automatic folding sewing machine with a tail includes a machine base 1, which is constructed of a metal frame and possesses high rigidity. The machine base 1 is equipped with a control panel containing a controller that integrates sensor signals (such as position and pressure detection) to coordinate the timing of the drive components. The control panel also features a human-machine interface for controlling the equipment. A sewing platform 2 is mounted on the machine base 1, and a sewing machine body 3 is mounted on the machine base 1, opposite the sewing platform 2. The sewing machine body 3 includes components such as a needle bar and a hook and shuttle mechanism. The specific structure and working principle of the sewing machine body 3 are mature existing technologies and will not be elaborated upon here. The sewing machine body 3 is equipped with a fiber optic sensor, which can sense the position of the fabric, which is beneficial to the sewing work. The machine base 1 is equipped with a folding mechanism and a winding mechanism. The folding mechanism includes a support platform 5, which is driven to move horizontally by a drive cylinder 6 installed on the machine base 1. A folding plate 8 is connected to the support platform 5 through an electric slider. An electric slide groove is opened on the support platform 5. The electric slider slides in the electric slide groove. The folding plate 8 is L-shaped. The drive cylinder 6 can drive the support platform 5 to move horizontally. The electric slider can press the fabric downwards and fold it.

[0021] The winding mechanism includes a winding roller 9, which is driven to rotate by a drive motor 10. The winding roller 9 is provided with a slot 11 for locking the end of the belt tail. When the end of the belt tail is locked into the slot 11, the drive motor 10 can wind up the belt tail when it drives the winding roller 9 to rotate.

[0022] The machine base 1 is equipped with a guide table 4 located between the folding mechanism and the winding mechanism. A rotatable pressure roller is installed on the guide table 4. The rotation of the pressure roller can exert pressure on the belt tail, which is beneficial for sewing. One end of the belt tail is placed on the folding mechanism and the other end is wound around the winding mechanism. The machine base 1 is equipped with a pressing mechanism located between the folding mechanism and the sewing machine body 3. The pressing mechanism includes a pressing rod 12. The pressing rod 12 is driven to move horizontally by an electric telescopic rod 13 installed on the machine base 1. The electric telescopic rod 13 drives the pressing rod 12 to extend and retract, so that the pressing rod 12 presses on the belt tail, thereby enabling the folding mechanism to fold it.

[0023] The machine base 1 is provided with a support platform 14, and the support platform 14 is provided with a rod insertion groove 15 located on the same line as the pressing rod 12. After sewing is completed, the rod can be inserted into the cavity formed by the folding of the tail through the rod insertion groove 15 to support it.

[0024] The machine 1 is equipped with a wire end processing mechanism for cutting and collecting wire ends. The wire end processing mechanism includes a support frame 16 mounted on the machine 1, a first control cylinder 17 mounted on the support frame 16, a cutting plate 18 mounted on the end of the first control cylinder 17, a wire heating plate mounted on the end of the cutting plate 18, and an electric heating wire installed inside the wire heating plate. The wire heating plate cuts the wire end by heating it, which can reduce the formation of burrs on the wire end. A wire suction head 19 is mounted on the support frame 16. A hook needle driven by a second control cylinder is installed inside the wire suction head 19. The wire suction head 19 is connected to a suction pump 7 through a connecting pipe. A wire collection box is mounted on the suction pump 7. The hook needle can hook the wire end into the wire suction head 19, and the suction pump 7 can suck the wire end into the wire collection box for collection, which is convenient for centralized processing.

[0025] The functional principle of this utility model can be explained through the following operation methods:

[0026] In this utility model, when the automatic folding sewing machine with a belt tail is working, the belt tail is passed through the guide table 4, and one end of the belt tail is placed on the folding plate 8, while the other end is wrapped around the take-up roller 9. The end of the belt tail is then inserted into the slot 11. The electric telescopic rod 13 drives the pressing rod 12 to extend, so that the pressing rod 12 presses on the belt tail. The drive cylinder 6 is started to drive the support platform 5 to move horizontally, so that the end of the belt tail is folded around the pressing rod 12. The folding plate 8 moves downward so that the end of the belt tail covers the pressing rod 12. The folding plate 8 is L-shaped and can press down and fix the end of the belt tail. The sewing machine body 3 is started to sew the end of the belt tail.

[0027] After sewing is completed, the first control cylinder 17 drives the cutting plate 18 to move, so that the hot iron plate burns off the thread end. The hook hooks the thread end into the suction head 19, and the suction pump 7 sucks the thread end into the collection box for collection. The electric telescopic rod 13 drives the pressing rod 12 to be pulled out from the cavity formed by the folding. The worker inserts the support rod into the cavity through the insertion rod slot 15 on the support platform 14 to support it. The drive motor 10 drives the take-up roller 9 to rotate and take up the tail of the belt, completing the sewing work.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
