Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric bonding and processing technology, specifically to a shaping tooling for bonding strip fabrics. Background Technology
[0002] A fusible interfacing machine, also known as a bonding machine, is used in garment manufacturing. When bonding interfacing and fabric, a hot melt adhesive sheet is pre-fixed inside the fabric strips. The fabric is then manually folded, and the folded ends are bonded together by the heat of the fusible interfacing machine. This process requires continuous manual assistance with the folding, is labor-intensive, and demands a high level of skill and expertise from the workers. Even a slight deviation in folding can cause fabric distortion, asymmetry, and other defects during subsequent bonding, affecting the overall appearance and comfort of the garment.
[0003] Furthermore, when processing and bonding multiple fabrics simultaneously, multiple workers are needed to handle the folding operations of different fabrics. This presents challenges due to limited workspaces, making it inconvenient for workers to stand. Additionally, in summer, the bonding machine generates significant heat, and operators working in such a high-temperature environment for extended periods are prone to discomfort. Utility Model Content
[0004] This utility model provides a shaping fixture for bonding strip fabrics, which solves the technical problems in the prior art where bonding strip fabrics requires manual folding, resulting in high labor intensity, low efficiency, and a lack of consistent operation.
[0005] To solve the above problems, the present invention provides a shaping fixture for bonding strip fabrics, which adopts the following technical solution: It includes an inner support shell and an outer support shell. The outer support shell is fixedly installed at one end of the inner support shell. A U-shaped cavity is formed between the inner support shell and the outer support shell. A guide groove is provided in the middle of the outer support shell along its length.
[0006] Furthermore, the length of the inner support shell is greater than the length of the outer support shell, and the portion of the inner support shell extending out of the outer support shell forms a guide support portion.
[0007] Furthermore, the guide support is a flared structure that gradually increases in size from one end near the outer support shell to the other end.
[0008] Furthermore, a limiting frame for limiting the fabric strip is provided outside the guide support.
[0009] The limiting frame includes a U-shaped frame surrounding the guide support and away from the outer support shell, and one end of the U-shaped frame is provided with a straight frame pointing towards the outer support shell.
[0010] Furthermore, the end of the guide support that is away from the outer support shell is provided with an inwardly curved portion.
[0011] Furthermore, both the inner and outer support shells have U-shaped cross-sections. The ends of the two side plates formed by the U-shaped opening of the outer support shell are provided with arc-shaped flange structures. The arc-shaped flange structures are respectively wrapped around the ends of the two side plates of the inner support shell, and the ends of the arc-shaped flange structures are welded and fixed to the inner wall of the side plates of the inner support shell.
[0012] Furthermore, the bottom of the outer support shell is provided with a connecting plate for external fixed installation, and both ends of the connecting plate extend out of the outer support shell and are provided with waist holes on the extended parts.
[0013] The beneficial effects of the shaping fixture for bonding strip fabrics provided by this utility model are: 1. In this utility model, the inner and outer support shells cooperate to form a U-shaped cavity, realizing the automated transformation of the fabric strip from being laid flat to being folded in half. This eliminates the tedious process of traditional manual folding, significantly shortens the operation time, and substantially improves production efficiency. It is especially suitable for large-scale production scenarios and can effectively meet high-volume production demands.
[0014] 2. In practical use, the guide groove located in the middle of the outer support shell along its length provides convenience for the operator to guide the fabric with their fingers. When the U-shaped cavity is long, soft fabric is difficult to pass through smoothly by pushing it through only one section. The guide groove design allows the fabric to pass through the U-shaped cavity more easily and smoothly, effectively solving the problem of difficult fabric passage.
[0015] 3. The guide support portion formed by the inner support shell extending beyond the outer support shell in this utility model helps the fabric spread smoothly when entering the tooling. The arc-shaped portion at the end avoids friction between the fabric and sharp edges, preventing fabric damage and ensuring the integrity and quality of the fabric. The limiting frame set outside the guide support portion, through the surrounding U-shaped frame and the straight frame pointing towards the outer support shell, effectively restricts the position of the fabric strip. This allows the fabric to conform as closely as possible to its surface when passing through the guide support portion, accurately entering the U-shaped groove cavity along a predetermined path, greatly improving the accuracy and stability of the fabric strip folding, reducing the defect rate caused by fabric deviation, and improving product quality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0019] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.
[0020] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0021] An embodiment of a shaping fixture for bonding strip fabrics provided by this utility model: like Figures 1 to 5 As shown, It includes an inner support shell 1 and an outer support shell 2. The outer support shell 2 is fixedly installed at one end of the inner support shell 1. A U-shaped cavity 3 is formed between the inner support shell 1 and the outer support shell 2. A guide groove 21 is provided in the middle of the outer support shell 2 along its length.
[0022] The U-shaped cavity 3 is formed by the cooperation of the inner support shell 1 and the outer support shell 2, which realizes the automated processing of the fabric strip from flat to folded, eliminating the tedious manual folding, reducing labor intensity and improving work efficiency.
[0023] By setting the guide groove 21, it is easy to guide the fabric with your fingers, making it easier and smoother for the soft fabric to pass through the U-shaped cavity 3. This avoids the situation where, when the U-shaped cavity 3 is long, the fabric is difficult to pass through after a certain period of pushing.
[0024] In this embodiment, the length of the inner support shell 1 is greater than the length of the outer support shell 2, and the portion of the inner support shell 1 that extends out of the outer support shell 2 forms a guide support portion 11.
[0025] Among them, the guide support part 11 is a flared structure that gradually increases in size from one end near the outer support shell 2 to the other end.
[0026] Among them, the end of the guide support part 11 away from the outer support shell 2 is provided with an inwardly turned arc-shaped part 111.
[0027] The guide support 11 allows the fabric to spread out and pass through smoothly. The curved part 111 makes the fabric pass through more smoothly, avoiding friction between the fabric and sharp edges when passing through, preventing damage to the fabric, and ensuring the integrity and quality of the fabric.
[0028] In this embodiment, a limiting frame 4 for limiting the fabric strip is provided outside the guide support part 11. The limiting frame 4 includes a U-shaped frame 41 surrounding the guide support part 11 and away from one end of the outer support shell 2, and a straight frame 42 pointing towards the outer support shell 2 is provided at one end of the U-shaped frame 41.
[0029] The limiting effect of the limiting frame 4 allows the fabric to pass through the guide support part 11 as closely as possible to the surface of the guide support part 11, ensuring that the fabric enters the U-shaped cavity 3 accurately according to the predetermined path, thereby improving the accuracy and stability of folding.
[0030] In this embodiment, both the inner support shell 1 and the outer support shell 2 have a U-shaped cross-section. The ends of the two side plates formed by the U-shaped opening of the outer support shell 2 are provided with arc-shaped flange structures 22. The arc-shaped flange structures 22 are respectively wrapped around the ends of the two side plates of the inner support shell 1. The ends of the arc-shaped flange structures 22 are respectively welded and fixed to the inner wall of the side plates of the inner support shell 1.
[0031] This welded structure can withstand various forces when the fabric passes through it, and is not prone to loosening or damage, thus ensuring the overall structural stability and service life of the tooling.
[0032] In this embodiment, the bottom of the outer support shell 2 is provided with a connecting plate 5 for external fixed installation. Both ends of the connecting plate 5 extend out of the outer support shell 2 and are provided with waist holes 51 on the extended parts.
[0033] The connecting plate 5 facilitates the fixing of the fixture to the feed inlet of the bonding machine. A fixed connection is achieved by bolts passing through the waist hole and the base plate at the feed inlet of the bonding machine.
[0034] In practical use, multiple of these fixtures can be arranged and fixed along the width of the feed inlet to achieve folding and bonding of fabric strips, effectively improving work efficiency.
[0035] In this embodiment, the shaping fixture for bonding strip fabrics is first fixed at the feed inlet of the bonding machine. Then, the bonding machine is preheated. Subsequently, one end of the fabric strip with the hot melt adhesive sheet is passed through the limiting frame 4 and then into the U-shaped groove 3. By using fingers to act on the guide groove 21, the fabric is pushed, thereby enabling the fabric strip to quickly pass through the U-shaped groove 3. After the end that has passed through enters the bonding machine, the internal guiding structure allows the fabric strip passing through the U-shaped groove 3 to continuously enter the bonding machine in a folded form, avoiding manual folding of the fabric and reducing the intensity of manual labor.
