Description
Technical Field
[0001] This utility model relates to the field of shoe upper production technology, specifically a sewing device for training shoes. Background Technology
[0002] Training shoes are professional footwear designed specifically for military training, outdoor sports, and other scenarios. They combine functionality and comfort, typically featuring a wear-resistant and slip-resistant rubber outsole to enhance grip, and an upper made of breathable mesh or waterproof leather. They are paired with a cushioned midsole to reduce foot pressure, and reinforced structures at the toe and heel to protect the feet. The design emphasizes lightweight flexibility, making them suitable for long-distance walking, running, and tactical maneuvers. They are widely used in military training, firefighter operations, outdoor adventures, and other fields.
[0003] The production of training shoes begins with cutting the material. After the upper material is cut, the toe, body and other parts are spliced together using a training shoe sewing device. The shoelace holes are reinforced and accessories such as Velcro are sewn on. The sole is injection molded and processed with anti-slip patterns. Finally, the upper and sole are joined together by adhesive or adhesive-stitched combination. After the finished product passes quality inspection, it is packaged and shipped out of the factory.
[0004] When sewing training shoes, the angle of the shoes needs to be constantly adjusted. Existing sewing devices are cumbersome to adjust when sewing shoes, resulting in low efficiency. Therefore, a sewing device for training shoes is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A sewing device for training shoes, comprising a sewing table; a sliding seat slidably connected to the top of the sewing table; a first fixed seat fixedly connected to the top of the sliding seat; a pair of first support frames slidably connected to the side wall of the first fixed seat; a bidirectional screw threadedly connected to the middle of the first support frame; a rotating seat rotatably connected to the top of the first support frame; a pair of clamping assemblies fixedly connected to the side wall of the rotating seat; a tension spring fixedly connected to the middle of the clamping assemblies; and a second support frame fixedly connected to the top of the sewing table; An electric push rod is fixedly connected to the top of the second support frame; a first sewing needle is fixedly connected to the bottom of the electric push rod; by applying a pulling force to the clamping component, the tension spring is stretched, and the shoe is placed and then elastically reset to fix it. Compared with the strap buckle method, the clamping time is greatly shortened, and the clamping force is uniform and stable, reducing the sliding and displacement of the shoe during the sewing process and increasing the sewing accuracy. Applying a pushing force to the clamping component can drive the rotating seat to rotate on the side wall of the first support frame, realizing the arbitrary angle adjustment of the training shoe during the sewing process without stopping the machine to re-clamp it. It can meet the requirements of shoe upper curve sewing and improve sewing efficiency and flexibility.
[0007] Preferably, a second fixed seat is fixedly connected to the bottom end of the electric push rod; a pin is slidably connected to the middle of the second fixed seat; a second sewing needle is fixedly connected to the bottom end of the second fixed seat; the second sewing needle is positioned close to the first sewing needle; by simultaneously sewing with the first and second sewing needles at the same position, the stitch density on the surface of the training shoe can be increased. Compared with a single sewing head, the number of stitches inside the training shoe can be increased, effectively enhancing the sturdiness of the shoe body and extending the service life of the training shoe.
[0008] Preferably, a spring telescopic rod is fixedly connected to the bottom end of the electric push rod; a presser foot is fixedly connected to the bottom end of the spring telescopic rod; and a flexible pad is fixedly connected to the bottom end of the presser foot. By having the flexible pad contact the surface of the training shoe before the first sewing needle, uneven areas such as wrinkles and protrusions on the shoe surface can be pre-flattened, reducing skewing, skipped stitches, or missed stitches caused by unevenness on the shoe surface. The flexible material used in the flexible pad can reduce indentations, deformation, or material damage to the shoe surface caused by a hard presser foot, thereby improving the quality of the finished product.
[0009] Preferably, a container is fixed to the top of the second support frame; a material tube is fixed to the side wall of the container; a retaining ring is fixed to the side wall of the electric push rod; after the hot melt adhesive flows out from the material tube, it can be evenly applied to the gaps between the stitches along the seam, cooperate with the first sewing needle to fill the seam holes and form a waterproof and anti-detachment layer, improve the sealing performance of the seams of the training shoes, and reduce water vapor penetration or seam wear and cracking.
[0010] Preferably, a heating rod is fixedly connected to the bottom of the container; an insulation layer is fixedly connected to the side wall of the material tube; the heating rod heats the inside of the container, reducing the natural cooling of the hot melt adhesive inside the container during long-term use, keeping it in a molten state, reducing blockage or uneven application caused by adhesive solidification, and increasing the stability during application.
[0011] Preferably, an elastic cloth is fixed to the side wall of the clamping assembly; the elastic cloth is positioned near the tension spring; by blocking the tension spring from the side surface of the training shoe, the tension spring directly contacts the shoe surface during extension and retraction, thus reducing the risk of scratching the material and ensuring the appearance of the training shoe remains intact. The elastic cloth can be pulled along with the tension spring, and when the clamping force is adjusted by the extension and retraction of the tension spring, the elastic cloth always fits tightly against the shoe surface. It can also wrap the training shoe, further encasing it in the middle of the clamping assembly.
[0012] The advantages of this utility model are:
[0013] 1. The sewing device for training shoes described in this utility model applies a tension force to the clamping component to stretch the tension spring, and then the shoe is placed in the clamp and elastically resets to secure it. Compared with the strap buckle method, this significantly shortens the clamping time, and the clamping force is uniform and stable, reducing the sliding and displacement of the shoe during the sewing process and increasing the sewing accuracy. Applying a pushing force to the clamping component can drive the rotating seat to rotate on the side wall of the first support frame, realizing arbitrary angle adjustment of the training shoe during the sewing process without stopping the machine to re-clamp it. It can meet the requirements of shoe upper curve sewing, improving sewing efficiency and flexibility.
[0014] 2. The sewing device for training shoes described in this utility model can increase the stitch density on the surface of the training shoes by simultaneously sewing with a first sewing needle and a second sewing needle at the same position.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 5 As shown in the embodiment of this utility model, a sewing device for training shoes includes a sewing table 1; a sliding seat 11 is slidably connected to the top of the sewing table 1; a first fixed seat 12 is fixedly connected to the top of the sliding seat 11; a pair of first support frames 13 are slidably connected to the side wall of the first fixed seat 12; a bidirectional screw 16 is threadedly connected to the middle of the first support frame 13; a rotating seat 14 is rotatably connected to the top of the first support frame 13; a pair of clamping assemblies 15 are fixedly connected to the side wall of the rotating seat 14; a tension spring 110 is fixedly connected to the middle of the clamping assembly 15; the top of the sewing table 1 is fixedly connected to the first fixed seat 12; a pair of first support frames 13 are slidably connected to the side wall of the first fixed seat 12; a pair of first support frames 13 are threadedly ... A second support frame 17 is connected; an electric push rod 18 is fixedly connected to the top of the second support frame 17; a first sewing needle 19 is fixedly connected to the bottom of the electric push rod 18; during operation, the training shoe to be sewn is placed in the middle of a pair of clamping components 15, and a pulling force is applied to the clamping components 15. The tension spring 110 in the middle of the clamping components 15 is stretched by the pulling force. After the training shoe is placed in the middle of the clamping components 15, the pulling force aligned with the clamping components 15 is released, and the tension spring 110 elastically returns to its original position, which can fix the training shoe in the middle of the clamping components 15. After the training shoe is fixed, the electric push rod 18 is activated to drive the first sewing needle. As the first sewing needle 19 descends, it contacts the surface of the training shoe to begin sewing. During sewing, the training shoe applies a pushing force to the clamping assembly 15, causing the rotating seat 14 to rotate on the side wall of the first support frame 13. This allows the training shoe to adjust its angle while the first sewing needle 19 is sewing. When switching to different sizes of training shoes, a rotational force is applied to the bidirectional screw 16, causing the pair of first support frames 13 to adjust their spacing. This allows the clamping assembly 15 to adapt to clamping different sizes of training shoes. During sewing, the training shoe applies a pushing force to the sliding seat 11, causing the sliding seat 11 to move on the sewing table. 1. Surface movement allows the training shoe to be adjusted directly below the tension spring 110; by applying tension to the clamping component 15, the tension spring 110 is stretched, and after the shoe is placed, it is elastically reset and fixed. Compared with the strap buckle method, the clamping time is greatly shortened, and the clamping force is uniform and stable, reducing the sliding and displacement of the shoe during sewing and increasing sewing accuracy. Applying a pushing force to the clamping component 15 can drive the rotating seat 14 to rotate on the side wall of the first support frame 13, realizing arbitrary angle adjustment of the training shoe during the sewing process without stopping the machine to re-clamp, which can meet the requirements of shoe upper curve sewing and improve sewing efficiency and flexibility.
[0025] like Figure 1 and Figure 5 As shown, the bottom end of the electric push rod 18 is fixedly connected to a second fixed seat 2; a pin 21 is slidably connected to the middle of the second fixed seat 2; a second sewing needle 22 is fixedly connected to the bottom end of the second fixed seat 2; the second sewing needle 22 is positioned near the side of the first sewing needle 19; during operation, when the first sewing needle 19 is sewing the training shoe held in the middle of the clamping assembly 15, the second sewing needle 22 can be embedded into the middle of the second fixed seat 2. After the second sewing needle 22 is embedded into the middle of the second fixed seat 2, the pin 21 is inserted into the middle of the second fixed seat 2 to fix the second sewing needle 22, so that the first sewing needle 19 and the second sewing needle 22 sew on the same surface of the training shoe; by sewing simultaneously at the same position by the first sewing needle 19 and the second sewing needle 22, the stitch density on the surface of the training shoe can be increased. Compared with a single sewing head, the number of stitches inside the training shoe can be increased, effectively enhancing the sturdiness of the shoe body and extending the service life of the training shoe.
[0026] like Figure 1 and Figure 3 As shown, a spring telescopic rod 3 is fixedly connected to the bottom end of the electric push rod 18; a presser foot 31 is fixedly connected to the bottom end of the spring telescopic rod 3; and a flexible pad 32 is fixedly connected to the bottom end of the presser foot 31. During operation, when the first sewing needle 19 contacts the surface of the training shoe for sewing, the flexible pad 32 can first contact the surface of the training shoe to flatten the uneven areas on the surface of the training shoe. After the flexible pad 32 flattens the training shoe, the first sewing needle 19 continues to fall, and the spring telescopic rod 3 can retract, allowing the first sewing needle 19 to penetrate deep into the inside of the training shoe for sewing. The flexible pad 32 will not obstruct the descent of the first sewing needle 19. By having the flexible pad 32 contact the surface of the training shoe before the first sewing needle 19, uneven areas such as wrinkles and protrusions on the shoe surface can be pre-flattened, reducing the risk of crooked stitches, skipped stitches, or missed stitches caused by unevenness on the shoe surface. The flexible material used in the flexible pad 32 can reduce shoe surface indentations, deformation, or material damage caused by the hard presser foot 31, thereby improving the quality of the finished product.
[0027] like Figure 1 and Figure 4 As shown, a container 4 is fixedly connected to the top of the second support frame 17; a material tube 41 is fixedly connected to the side wall of the container 4; a retaining ring 42 is fixedly connected to the side wall of the electric push rod 18; during operation, when the first sewing needle 19 is sewing the training shoe, hot melt adhesive can be added to the inside of the container 4, and the hot melt adhesive can flow out from the middle of the material tube 41, cooperating with the first sewing needle 19 that is sewing, and applying it to the seam; after the hot melt adhesive flows out from the material tube 41, it can be evenly applied to the gap between the stitches along the seam, cooperating with the first sewing needle 19 to fill the seam holes and form a waterproof and anti-detachment layer, improving the sealing performance of the seam of the training shoe, reducing water vapor penetration or seam wear and cracking.
[0028] like Figure 1 and Figure 2 As shown, a heating rod 5 is fixedly connected to the bottom of the container 4; a heat insulation layer 51 is fixedly connected to the side wall of the material tube 41. During operation, the hot melt adhesive stored inside the container 4 will cool down after prolonged use. At this time, the heating rod 5 heats the inside of the container 4, so that the hot melt adhesive continues to flow. The heat insulation layer 51 can wrap the material tube 41 to retain the heat in the middle of the material tube 41 inside. By heating the inside of the container 4 with the heating rod 5, the natural cooling of the hot melt adhesive inside the container 4 during prolonged use is reduced, so that it always remains in a molten state, reducing blockage or uneven application caused by the solidification of the adhesive, and increasing the stability during application.
[0029] like Figure 1 and Figure 3 As shown, an elastic cloth 6 is fixed to the side wall of the clamping assembly 15; the elastic cloth 6 is located near the tension spring 110; during operation, when the training shoe in the middle of the clamping assembly 15 is being sewn, the tension spring 110 will touch the side surface of the training shoe, causing scratches. The elastic cloth 6 can block the tension spring 110 and the middle of the training shoe. When the tension spring 110 extends and retracts, the elastic cloth 6 can be pulled along with the tension spring 110; by blocking the tension spring 110 and the side surface of the training shoe with the elastic cloth 6, the direct contact between the tension spring 110 and the shoe surface during the extension and retraction process is reduced, which causes scratches to the material and ensures that the appearance of the training shoe is intact. The elastic cloth 6 can be pulled along with the tension spring 110. When the tension spring 110 extends and retracts to adjust the clamping force, the elastic cloth 6 always fits tightly against the shoe surface. It can also wrap the training shoe, further wrapping the training shoe in the middle of the clamping assembly 15.
[0030] Working principle: The training shoe to be sewn is placed in the middle of a pair of clamping components 15. A pulling force is applied to the clamping components 15, causing the tension spring 110 in the middle of the clamping components 15 to stretch. After the training shoe is placed in the middle of the clamping components 15, the pulling force aligned with the clamping components 15 is released, and the tension spring 110 elastically returns to its original position, fixing the training shoe in the middle of the clamping components 15. After the training shoe is fixed, the electric push rod 18 is activated, driving the first sewing needle 19 to descend. The first sewing needle 19 contacts the surface of the training shoe and begins sewing. During sewing, the training shoe can apply a pushing force to the clamping components 15, causing the rotating seat 14 to rotate on the side wall of the first support frame 13, thus allowing the shoe to move. The angle of the training shoe can be adjusted when the first sewing needle 19 is sewing. When switching to different sizes of training shoes, a rotational force is applied to the bidirectional screw 16, which drives the pair of first support frames 13 to adjust the spacing, so that the pair of clamping components 15 can adapt to clamping different models of training shoes. When the training shoe is being sewn, a pushing force can be applied to the sliding seat 11, which moves the sliding seat 11 on the surface of the sewing table 1, so that the training shoe can be adjusted to be directly below the tension spring 110. When the first sewing needle 19 is sewing the training shoe clamped in the middle of the clamping component 15, the second sewing needle 22 can be inserted into the middle of the second fixed seat 2. After the second sewing needle 22 is inserted into the middle of the second fixed seat 2, the insertion... Pin 21 is inserted into the middle of the second fixing seat 2 to fix the second sewing needle 22, so that the first sewing needle 19 and the second sewing needle 22 sew on the same surface of the training shoe. When the first sewing needle 19 contacts the surface of the training shoe, the flexible pad 32 can first contact the surface of the training shoe to flatten the uneven parts of the surface. After the flexible pad 32 flattens the training shoe, the first sewing needle 19 continues to fall, and the spring telescopic rod 3 can retract, so that the first sewing needle 19 can penetrate into the inside of the training shoe to sew. The flexible pad 32 will not block the descent of the first sewing needle 19. When the first sewing needle 19 is sewing the training shoe, hot melt glue can be added to the container 4. Molten adhesive can flow out from the middle of the tube 41 and cooperate with the first sewing needle 19 being sewn to apply it to the sewing line. The hot melt adhesive stored inside the container 4 will cool down after long-term use. At this time, the heating rod 5 heats the inside of the container 4 to keep the hot melt adhesive in a continuous flow state. The insulation layer 51 can wrap the tube 41 to retain the heat in the middle of the tube 41. When the training shoe in the middle of the clamping component 15 is sewn, the tension spring 110 will touch the side surface of the training shoe and cause scratches. The elastic cloth 6 can block the tension spring 110 and the middle of the training shoe. When the tension spring 110 is stretched, the elastic cloth 6 can be stretched together with the tension spring 110.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
