Description

Technical Field

[0001] The present invention belongs to the technical field of down jacket processing, and particularly relates to a processing method for sewing threads used in anti-feather-loss down fabrics. Background Art

[0002] Down is by far the best natural material for human warmth. After being processed through processes such as washing, drying, and grading, it is made into down jackets. Compared with artificial materials, the warmth retention ability of down is three times that of general artificial materials.

[0003] However, during the use of down jackets, a phenomenon of feather loss occurs, that is, down drills out from the sewing threads, resulting in the loss of down and uneven distribution of down. Summary of the Invention

[0004] The purpose of the present invention is to provide a processing method for sewing threads used in anti-feather-loss down fabrics to solve the problems raised in the above background art.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0006] A processing method for sewing threads used in anti-feather-loss down fabrics includes the following steps:

[0007] S1: Wind the special sewing threads for down jackets around a spool, place the spool on one side of the gluing device, and preheat the sewing threads.

[0008] S2: After passing the head of the sewing threads in S1 through the gluing device, load it onto the sewing machine for down jacket processing.

[0009] S3: Start the sewing machine in S2, drive the sewing threads to continuously pass through the gluing device, use the gluing device to brush glue on the sewing threads, and the gluing device forms intermittent glue dots on the sewing threads, and the glue dots just fit the gaps between the sewing threads and the fabric.

[0010] Preferably, the gluing device used in S1 - S3 includes a glue pool for holding glue, a rotating mechanism horizontally arranged on the glue pool, and a glue-brushing mechanism for applying glue to the sewing threads on the rotating mechanism, and the rotating mechanism is used to drive the glue-brushing mechanism to rotate;

[0011] The glue-brushing mechanism includes a rotating cylinder, and two or more brush groups are arranged on the rotating cylinder at equal intervals along its axial direction, and each brush group includes two or more glue brushes arranged along the circumferential direction of the rotating cylinder for brushing glue on the sewing threads.

[0012] Preferably, the rotating mechanism includes a driving motor arranged on the glue pool and a rotating shaft connected to the driving motor.

[0013] Preferably, a baffle for restricting the position of the sewing thread is provided on the glue pool. An expansion rod for driving the baffle to move is provided between the baffle and the glue pool. Exhaust holes are provided on the side wall of the expansion rod. Two or more pressing blocks are equidistantly arranged along the circumferential direction of the rotating shaft. An air cylinder for driving the expansion and contraction of the expansion rod is provided on the glue pool. A return spring for driving the air cylinder to rebound is provided in the air cylinder.

[0014] Preferably, the expansion rod is obliquely arranged, and the inclination angle of the expansion rod is 30-60°.

[0015] Preferably, a scraper for removing excess glue on the sewing thread is provided on the glue pool.

[0016] Preferably, a vibration spring for driving the scraper to vibrate is provided on the baffle.

[0017] Preferably, the scraper is of a J-shaped structure.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1) By intermittently applying glue to the sewing thread, the glue can fill the gap between the sewing thread and the down fabric, effectively preventing the down from drilling out from the gap, and improving the anti-down-leakage effect of the down fabric.

[0020] 2) The present invention applies glue to the sewing thread by rubbing, ensuring that the glue can be in full contact with the sewing thread. The scraper is used to contact the sewing thread. During the contact process, not only the excess glue on the sewing thread is removed, but also the glue can be evenly applied to the sewing thread, so that the glue can be appropriately distributed on the surface of the sewing thread.

[0021] 3) By preheating the sewing thread, the process of the sewing thread driving the glue to move will not cause the glue to cool and harden in advance, thus ensuring the adhesion between the glue, the sewing thread and the fabric. Description of the Drawings

[0029] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non - essential improvements and adjustments to the present application according to the above application content.

[0030] Embodiment 1

[0031] As Figures 1-6 shown, a processing method for the sewing thread used in anti - feather - leakage down fabric includes the following steps:

[0032] S1: Wind the special sewing thread for down jackets around a spool, place the spool on one side of the glue - applying device, and pre - heat the sewing thread; the sewing thread is a finished product, and winding it around the spool enables the sewing thread to be pulled at a constant speed, facilitating continuous processing of the sewing thread; the pre - heated sewing thread can ensure that the glue will not quickly cool and harden after being brushed with glue, thus ensuring the viscosity and permeability of the glue are not affected.

[0033] S2: Feed the head of the sewing thread in S1 into the sewing machine for down jacket processing after passing through the glue - applying device; the sewing thread passing through the glue - applying device is specially processed and can change the service performance of the down jacket.

[0034] S3: Start the sewing machine in S2, drive the sewing thread to continuously pass through the glue - applying device, use the glue - applying device to brush the adhesive on the sewing thread, and the glue - applying device forms intermittent glue dots on the sewing thread, and the glue dots just fit the gap between the sewing thread and the fabric; after the sewing thread is brushed with the adhesive and passes through the down fabric, the gap between the sewing thread and the fabric is filled with the adhesive. The adhesive can not only prevent the feathers from drilling out but also improve the adhesion between the sewing thread and the down fabric, and improve the tightness of the fabric.

[0035] As a further solution of the present invention, the glue - applying device used in S1 - S3 includes a glue pool 1 for containing the adhesive, a rotating mechanism horizontally arranged on the glue pool 1, and a glue - brushing mechanism for applying glue to the sewing thread on the rotating mechanism, and the rotating mechanism is used to drive the glue - brushing mechanism to rotate;

[0036] The glue - brushing mechanism includes a rotating cylinder 2, and two or more brush groups are equidistantly arranged along the axial direction of the rotating cylinder 2. Each brush group includes two or more glue brushes 3 arranged along the circumferential direction of the rotating cylinder 2 for brushing glue on the sewing thread.

[0037] In the above embodiment, when the sewing thread passes through the glue coating device, the rotating mechanism drives the glue brushing mechanism to rotate, lifting the adhesive tape in the glue pool 1 and adsorbing it on the surface of the glue brush 3 in the glue brushing mechanism. When the glue brush 3 contacts the sewing thread, the adhesive is adhered to the sewing thread. When the sewing thread is sewn on the down fabric by the sewing machine, the adhesive can fill the gaps of the sewing thread, thus effectively reducing the drilling out of the down.

[0038] As a further solution of the present invention, the rotating mechanism includes a driving motor 4 provided on the glue pool 1 and a rotating shaft 5 connected to the driving motor 4.

[0039] In the above embodiment, the driving motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the rotating cylinder 2 and the glue brush 3 to rotate.

[0040] As a further solution of the present invention, a baffle 6 for restricting the position of the sewing thread is provided on the glue pool 1. An expansion rod 7 for driving the baffle 6 to move is provided between the baffle 6 and the glue pool 1. Exhaust holes are provided on the side wall of the expansion rod 7. Two or more pressing blocks 8 are equidistantly provided along the circumferential direction of the rotating shaft 5. An air cylinder 9 for driving the expansion rod 7 to expand and contract is provided on the glue pool 1. A return spring for driving the air cylinder 9 to rebound is provided in the air cylinder 9.

[0041] As a further solution of the present invention, the expansion rod 7 is inclined, and the inclination angle of the expansion rod 7 is 30-60°.

[0042] In the above embodiment, when the glue brush 3 contacts the sewing thread, it will drive the sewing thread to produce a certain shaking, thus affecting the uniformity of glue application on the sewing thread, and only one side of the sewing thread can be brushed by the glue brush 3, which also limits the uniform distribution degree of the adhesive. The pressing blocks 8 are provided. During the rotation of the rotating shaft 5, the pressing blocks 8 are driven to rotate. When the pressing blocks 8 contact the air cylinder 9, the gas in the air cylinder 9 is pressed into the expansion rod 7 through the air pipe, causing the expansion rod 7 to elongate, so that the baffle 6 is driven. The baffle 6 and the glue brush 3 move closer to each other to clamp the sewing thread. During the clamping process, the glue brush 3 can press the sewing thread against the baffle 6, and drive the sewing thread to produce a certain rotation on the baffle 6 during the rotation of the glue brush 3, forming a rubbing effect, so as to apply glue to the sewing thread in a circular manner, and the adhesive can be evenly distributed on the sewing thread. When the pressing blocks 8 are away from the air cylinder 9, the return spring drives the air cylinder 9 to return to its original position, and the gas in the expansion rod 7 is discharged through the exhaust holes (the exhaust speed of the exhaust holes is less than the intake speed of the air cylinder 9), and the shortening of the expansion rod 7 drives the baffle 6 to return to its original position.

[0043] Among them, the expansion rod 7 is inclined, so that the baffle 6 moves obliquely upward, so that the sewing thread produces a certain rotation during the sliding process on the surface of the baffle 6, so that the sewing thread can be successfully coated with glue by the glue brush 3.

[0044] As a further solution of the present invention, a scraper 10 for removing excess adhesive on the sewing thread is provided on the glue pool 1.

[0045] In the above embodiment, the glue brush 3 often carries a large amount of adhesive, so that excess adhesive adheres to the sewing thread. The excess adhesive sticking to the down fabric causes waste and increases the cleaning workload of the down fabric. By providing the scraper 10, the sewing thread contacts the hanging plate, and during the process of the sewing thread being rubbed, the scraper 10 can rotate relative to the sewing thread. The scraper 10 scrapes off the excess adhesive on the sewing thread and can evenly apply the adhesive on the sewing thread, further improving the adhesion between the sewing thread and the down fabric.

[0046] As a further solution of the present invention, a vibration spring 11 for driving the scraper 10 to vibrate is provided on the baffle 6.

[0047] In the above embodiment, by providing the vibration spring 11, when the baffle 6 moves downward, it drives the vibration spring 11 to contact the scraper 10, so that the scraper 10 is squeezed and generates a certain vibration under the extrusion. During the vibration process, the scraper 10 shakes off the adhesive scraped from the sewing thread, keeping the scraper 10 clean and ensuring the coating effect of the scraper 10 on the sewing thread.

[0048] As a further solution of the present invention, the scraper 10 is of a J-shaped structure.

[0049] In the above embodiment, during the process of the sewing thread being rubbed, it will be driven downward by a certain distance, so that the sewing thread contacts the scraper 10. During the process of the sewing thread returning to its initial position, the sewing thread moves upward along the lower contour of the scraper 10 and generates a certain rotation during the movement, so that the scraper 10 can evenly apply the adhesive on the sewing thread to the sewing thread.

[0050] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
