Description

Technical Field

[0001] The present invention relates to the technical field of suture methods, and in particular to a suture method for a covering part. Background Art

[0002] In the prior art, most of the traditional seams of the covering parts are true seams. There are two kinds of processes: one is to separate the upper covering part and the lower covering part, and then fix the upper and lower covering parts together by clamping or the like; the other is the cloth bag method: sew a cloth bag and then turn it over and put it on the frame.

[0003] The advantage of method one is that the seam line is very straight, but the disadvantage is that it involves many processes and molds, the upper and lower parts need to be wrapped separately by manpower, and more glue is used, resulting in high total manpower and product costs.

[0004] The advantage of method 2 is that the frame is not divided into upper and lower parts, the fabrics are first sewn together by a sewing machine and then turned over, no glue is needed, and the labor and product costs are relatively low. The disadvantage is that the seams are not smooth and look ugly.

[0005] The coating methods of the prior art have the following disadvantages: (1) low efficiency and high cost; (2) manual operation and poor product consistency. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a covering sewing method to solve the problems raised in the background art.

[0007] In order to achieve the above-mentioned object of the invention, the present invention provides a covering part sewing method, the covering part sewing method comprising:

[0008] S1: The covering member includes an upper covering member and a lower covering member matched with the upper covering member. The upper covering member and the lower covering member are first connected together by snap-fitting. After the upper covering member and the lower covering member are matched, a seam is formed at the joint of the two members;

[0009] S2: cutting out an upper fabric block for covering the upper covering member, wherein the upper fabric block needs to be able to completely cover the area of ​​the upper covering member that needs to be covered, and a lower fabric block for covering the lower covering member, wherein the lower fabric block needs to be able to completely cover the area of ​​the lower covering member that needs to be covered;

[0010] S3: Press and tightly wrap the upper fabric block on the upper covering member through a pressing device, and press and tightly wrap the lower fabric block on the lower covering member through a pressing device, and connect the upper fabric block and the lower fabric block together through an ultrasonic heat-sealing process after wrapping, and wrap the entire covering member, and cut the edge material of the upper fabric block and the edge material of the lower fabric block after connection;

[0011] S4: After the edge material of the upper fabric block and the edge material of the lower fabric block are separated, the effect of the parting line has not yet been formed. The parting line shaping tool is used to extrude the parting line into the seam at the seam, thereby forming a straight and smooth parting line feature.

[0012] Furthermore, the area of ​​the upper fabric block is larger than the area that the upper covering member needs to cover, and the area of ​​the lower fabric block is larger than the area that the lower covering member needs to cover.

[0013] Furthermore, the position where the upper fabric block and the lower fabric block are connected in a circle is aligned with the seam.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The ultrasonic heat-sealing process is used to complete the fabric covering and connection cutting at one time, with high efficiency and good quality;

[0016] 2. Through the final shaping of the seam line tooling, a beautiful seam flatness is achieved;

[0017] 3. It can reduce labor costs and realize automated production. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a schematic structural diagram of the upper fabric block and the lower fabric block of the present invention when they are not covered with a covering member;

[0019] Figure 2 It is a schematic structural diagram of the upper fabric block and the lower fabric block after being covered with a covering member according to the present invention. DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the invention, rather than all the embodiments. The embodiments of the present invention are described below in conjunction with the drawings.

[0021] like Figure 1-2 As shown, a covering stitching method, the covering stitching method comprising:

[0022] S1: The covering member includes an upper covering member 1 and a lower covering member 2 matched with the upper covering member 1. The upper covering member 1 and the lower covering member 2 are first connected together by snapping and matching. After the upper covering member 1 and the lower covering member 2 are matched, a seam 3 is formed at the junction of the two. After the upper fabric block 4 and the lower fabric block 5 are covered, they are connected. After the connection, the excess fabric is cut off, and a circle of the connection of the fabric is pressed into the seam 3 to form the effect of a parting line 6.

[0023] S2: cutting out an upper fabric piece 4 for covering the upper covering member 1, the upper fabric piece 4 needs to be able to completely cover the area that needs to be covered by the upper covering member 1, and a lower fabric piece 5 for covering the lower covering member 2, the lower fabric piece 5 needs to be able to completely cover the area that needs to be covered by the lower covering member 2, the size of the upper fabric piece 4 is determined according to the size and shape of the upper covering member 1, and the size of the lower fabric piece 5 is determined according to the size and shape of the lower covering member 2;

[0024] S3: The upper fabric block 4 is tightly pressed and wrapped on the upper covering member 1 by a pressing device, and the lower fabric block 5 is tightly pressed and wrapped on the lower covering member 2 by a pressing device. After wrapping, the upper fabric block 4 and the lower fabric block 5 are connected together by an ultrasonic heat-sealing process, and the entire covering member is wrapped. After connection, the edge materials of the upper fabric block 4 and the lower fabric block 5 are cut;

[0025] S4: After the edge material of the upper fabric block 4 and the edge material of the lower fabric block 5 are separated, the effect of the parting line 6 has not yet been formed. The parting line shaping tool is used to squeeze the parting line 3 into the parting line 3, so as to form a straight and smooth parting line 6 feature;

[0026] The area of ​​the upper fabric block 4 is larger than the area that the upper covering member 1 needs to cover, and the area of ​​the lower fabric block 5 is larger than the area that the lower covering member 2 needs to cover;

[0027] The position where the upper fabric block 4 and the lower fabric block 5 are connected in a circle is aligned with the seam 3, and the connected circle is pressed into the seam 3, so that the characteristics of the seam line 6 can be formed;

[0028] Compared with the technical solutions in the prior art, this application has the following advantages:

[0029] The ultrasonic heat-sealing process is used to complete the fabric covering and edge connection at one time, with high efficiency and good quality.

[0030] Through the final shaping of the seam line 6 tooling, a beautiful seam flatness is achieved;

[0031] It can reduce labor costs and realize automated production.

[0032] The technical solution of the present invention is described above in conjunction with specific implementation methods, but it should be noted that the above descriptions are only for explaining the solution of the present invention and cannot be interpreted in any way as a specific limitation on the scope of protection of the invention. Based on the explanation here, those skilled in the art can think of other specific implementation methods or equivalent replacements of the present invention without creative work, and they will all fall within the scope of protection of the present invention.
