Abstract
Description
Technical Field
[0001] This utility model belongs to the field of edge binding machine technology, specifically relating to an edge binding machine for the production and processing of textile products. Background Technology
[0002] In the production and processing of textile products, the edge binding process is a crucial link. Its purpose is to wrap and sew the edges of the fabric to improve the durability and aesthetics of the product. With the continuous development of the textile industry, the market has increasingly stringent requirements for the quality of textile products, which has prompted the continuous optimization and improvement of the performance of edge binding machines.
[0003] Currently, there are various types of edge binding machines on the market, which meet production needs to a certain extent. However, in actual edge binding operations, existing edge binding machines have revealed many problems. The most prominent issue is that the tension of the edge binding strip is difficult to control during the edge binding process. When the tension of the edge binding strip is loose during feeding, it will cause wrinkles to form at the edges when the edge binding strip and the fabric are sewn together, seriously affecting the appearance quality of the product.
[0004] Furthermore, if the binding strip lacks tension adjustment during transport, it is easy for it to twist. This makes it impossible to adjust the binding strip according to different batches of fabric, which makes it difficult for the binding strip to adhere tightly and smoothly to the edge of the fabric, greatly reducing the binding effect and making it difficult to meet the production standards of high-quality textile products.
[0005] In summary, existing edge binding machines for textile manufacturing have significant shortcomings in the control of edge binding strip conveying. Utility Model Content
[0006] The purpose of this utility model is to provide a binding machine for the production and processing of textile products, which can accurately control the tightness of the binding strip, avoid wrinkling at the edges when sewing with the fabric due to loose tension, greatly improve the appearance quality of the product, and can adjust the tension of the binding strip to adapt to the characteristics of different batches of fabrics.
[0007] The specific technical solution adopted by this utility model is as follows:
[0008] A binding machine for manufacturing textile products includes a work platform, a sewing machine mounted on the top of the work platform, a rotating column rotatably connected to the top of the work platform, and a rotating frame movably connected to the outside of the rotating column, the rotating frame being used to transmit binding strips.
[0009] A pull-back assembly is installed on the outside of the rotating column, which is used to pull back the edge banding strip.
[0010] The pull-back assembly includes a top plate fixed to the top of the rotating column, at least one second locking block fixed to the bottom of the top plate, and multiple first locking blocks corresponding to the second locking blocks fixed to the top of the rotating frame.
[0011] A mounting shell is fixed on the top of the working platform and outside the rotating column. A torsion spring is installed inside the mounting shell, and the two ends of the torsion spring are respectively connected to the mounting shell and the rotating frame.
[0012] An adjustment assembly is installed on the outside of the rotating column, and the adjustment assembly is used to adjust the torque of the torsion spring.
[0013] The adjustment assembly includes a plurality of first springs fixed to the top of the mounting housing, with a rotating plate fixed to the top of each first spring, and the rotating plate being rotatably connected to the bottom end of the rotating frame.
[0014] The second card block has the same shape as the first card block but is arranged oppositely. The top of the first card block and the bottom of the second card block are both provided with inclined surfaces, and the sides of the first card block and the second card block that are far apart from each other are provided with flat surfaces.
[0015] Multiple fixing plates are installed on the outer side of the rotating frame. Multiple second springs are fixed on the side of the fixing plates near the rotating frame. An abutment plate is fixed on the end of the second spring near the rotating frame. Ball bearings are evenly arranged on the side of the abutment plate near the rotating frame.
[0016] The outer side of the rotating frame is uniformly provided with protrusions.
[0017] The technical effects achieved by this utility model are as follows:
[0018] This utility model, through the interlocking of the first and second locking blocks and the torsion limitation of the torsion spring, can precisely control the tightness of the binding strip, avoiding wrinkles at the edges when sewing with the fabric due to loose tension, and greatly improving the appearance quality of the product.
[0019] By pressing down the rotating frame, the first spring is compressed, which in turn adjusts the tension of the binding strip. The adjustment is made according to the characteristics of different batches of fabrics to ensure that the binding strip is tight and flat against the edge of the fabric, meeting the production standards of high-quality textile products and effectively making up for the shortcomings of existing binding machines in the control of binding strip conveying.

[0028] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0029] like Figures 1-6 As shown, a binding machine for textile manufacturing includes a work platform 1, a sewing machine 2 mounted on the top of the work platform 1, and a rotating column 3 rotatably connected to the top of the work platform 1. A rotating frame 4 is movably connected to the outside of the rotating column 3. The rotating frame 4 can be sleeved on the outside of the rotating column 3 and can rotate or slide on the outside of the rotating column 3. The rotating frame 4 is used to conduct the binding strip. Furthermore, the outer side of the rotating frame 4 is evenly provided with protrusions. By setting the protrusions, the friction between the binding strip and the rotating frame 4 is increased, thereby ensuring that the binding strip drives the rotating frame 4 to move when it is conducted and moved.
[0030] When binding the fabric, place the fabric on the work platform 1 and under the sewing machine 2. At this time, wrap the binding strip around the outside of the rotating frame 4 and extend one end to the bottom of the sewing machine 2. The user can bind the fabric by sewing the binding strip through the sewing machine 2.
[0031] A pull-back assembly is installed on the outside of the rotating column 3. The pull-back assembly is used to pull back the edge banding strip.
[0032] See attached document Figures 2-5 The pull-back assembly includes a top plate 8 fixed to the top of the rotating column 3, at least one second locking block 9 fixed to the bottom of the top plate 8, and multiple first locking blocks 7 corresponding to the second locking blocks 9 fixed to the top of the rotating frame 4.
[0033] A mounting shell 5 is fixed on the top of the work platform 1 and on the outside of the rotating column 3. A torsion spring 6 is installed inside the mounting shell 5, and the two ends of the torsion spring 6 are connected to the mounting shell 5 and the rotating frame 4 respectively. The torsion spring 6 has a small torque, so that the torsion spring 6 avoids causing a large tension on the edge strip.
[0034] When the binding strip is used to bind the fabric, when the binding strip is pulled toward the direction closer to the sewing machine 2, it can drive the rotating frame 4 to rotate. According to the above structure, the second locking block 9 has the same shape as the first locking block 7 but is arranged oppositely. The top of the first locking block 7 and the bottom of the second locking block 9 are both provided with inclined surfaces. The side of the first locking block 7 and the second locking block 9 that is far away from each other is provided with a flat surface. Due to the arrangement of the first locking block 7 and the second locking block 9, when the first locking block 7 rotates, the inclined surface of the first locking block 7 contacts the inclined surface of the second locking block 9, and the right angle surfaces face each other. At this time, the rotation of the rotating frame 4 can drive multiple first locking blocks 7 to rotate around the rotating frame 4.
[0035] The torsion of the torsion spring 6 causes the rotating column 3 to rotate, which in turn causes the top plate 8 and the second locking block 9 to rotate. At this time, the right angle of the second locking block 9 corresponds to the first locking block 7, and the contact between the second locking block 9 and the first locking block 7 causes the first locking block 7 to rotate in reverse. This ensures that the rotating frame 4 always has a rotating tendency. Due to the wrapping effect between the binding strip and the rotating frame 4, the binding strip has a slight pull-back effect, thus ensuring that the rotating frame 4 always contacts the fabric relatively smoothly and is not too loose, ensuring the beauty and effect of the binding.
[0036] An adjustment assembly is installed on the outside of the rotating column 3. The adjustment assembly is used to adjust the torque of the torsion spring 6.
[0037] See attached document Figure 3 The adjustment assembly includes multiple first springs 11 fixed to the top of the mounting housing 5. A rotating plate 10 is fixed to the top of the first spring 11, and the rotating plate 10 is rotatably connected to the bottom end of the rotating frame 4. This arrangement ensures that the first springs 11 will not be twisted when the rotating frame 4 rotates.
[0038] When the torque of the torsion spring 6 needs to be adjusted, the rotating frame 4 can be pushed down, thereby disengaging the first locking block 7 from the second locking block 9 and compressing the first spring 11. At this time, the top plate 8 can be screwed on to adjust the torque of the torsion spring 6. After the adjustment is completed, the rotating frame 4 is released, causing the first spring 11 to spring the rotating frame 4 to contact the top plate 8, thereby causing the first locking block 7 and the second locking block 9 to re-engage with each other, thus adjusting the torque of the torsion spring 6 and adjusting the tension of the binding strip.
[0039] See attached document Figure 6 Multiple fixing plates 12 are installed on the outer side of the rotating frame 4. Multiple second springs 13 are fixed on the side of the fixing plates 12 near the rotating frame 4. An abutment plate 14 is fixed on the end of the second spring 13 near the rotating frame 4. Ball bearings 15 are evenly arranged on the side of the abutment plate 14 near the rotating frame 4.
[0040] With this configuration, when the binding strip is wound and conducted on the outside of the rotating frame 4, the elastic force of the second spring 13 can push the abutment plate 14 and the ball bearing 15 closer to the binding strip, thereby pressing the binding strip and reducing the possibility of twisting or folding. The ball bearing 15 reduces the friction between the binding strip and the abutment plate 14 during the conduction movement, thus increasing the movement effect.
[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
