Description

Technical Field

[0001] This utility model relates to the field of garment processing, specifically an auxiliary device for making pocket openings on a flat sewing machine. Background Technology

[0002] A flatbed sewing machine is a machine that uses a single thread to create a stitch on the fabric, allowing one or more layers of fabric to interweave or sew together. It is generally divided into two types: one for thin materials and one for thick materials. Flatbed sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. Thin materials are generally used for knitwear, underwear, shirts, and uniforms, while thick materials are generally used for various sportswear, denim, fashion apparel, coats, shoes, hats, leather goods, and bags. The flatbed sewing machine is the most basic type of sewing equipment. It produces the simplest stitch, resulting in neat, beautiful, even, flat, and strong stitches. It is fast, easy to operate, and simple to understand. Flatbed sewing machines are needed when processing the opening of pressed bags.

[0003] The existing flat sewing machine bag-pressing device has the following defects during operation: When pressing the bag opening, the operator usually needs to manually align the bag opening, and then process it through the needle at the output end of the flat sewing machine. In this process, due to the lack of a mechanism to align the bag opening and facilitate its movement, when the operator operates it manually, the bag opening is not only prone to deviation when being dragged by the operator for processing, but also has extremely low efficiency and requires a high level of operator skill because it requires multiple adjustments, pressing and feeding. This affects the quality of the bag opening after processing. Utility Model Content

[0004] This utility model aims to provide an auxiliary device for making bag openings on a flat sewing machine. It is mainly used to solve the technical problem that the existing technology lacks a mechanism for aligning and moving the bag opening. As a result, when the bag opening is manually operated by the worker, it is not only easy to deviate when it is dragged by the worker, but also the efficiency is extremely low and the skill level of the worker is high when multiple adjustments, pressing and feeding are required, which affects the quality of the bag opening after processing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An auxiliary device for making a bag opening on a flat sewing machine includes a fixed plate, a flat sewing machine body mounted on the top of the fixed plate, a sliding plate on the top of the fixed plate, a movable plate slidably mounted on the outer side of the sliding plate, a guide plate fixedly connected to the bottom of the movable plate, a groove for sliding along the outer wall of the sliding plate on the top of the guide plate, a fixed rod fixedly connected to the top of the movable plate, a support spring mounted on the outer wall of the fixed rod, and a template slidably mounted on the outer wall of the fixed rod, the support spring being connected to the template, a working groove extending through the top and bottom of the template, the working groove being trapezoidal in shape, an embedding groove on the bottom of the template, an indicator plate fixedly connected to the front side of the template, three embedding blocks fixedly connected to the top of the movable plate, the three embedding blocks being located on both sides and the middle of the top of the movable plate respectively, and several embedding blocks being inserted into the embedding groove, and a bag opening body placed between the movable plate and the template.

[0006] The working principle and beneficial effects of this utility model: 1. Working Principle: When the template is pulled upwards, the template compresses the support spring, increasing the distance between the template and the moving plate. This facilitates the placement of the bag-pressing body. At this time, the indicator plate points to the center of the bag-pressing body surface, and the rear side of the bag-pressing body contacts the front side of the embedding block. The two sides of the bag-pressing body are aligned with the moving plate, ensuring accurate and neat placement of the bag-pressing body. Due to the reaction force of the support spring, the template presses the bag-pressing body. The embedding groove is fitted on the outer wall of the embedding block to press the rear side of the bag-pressing body, preventing skewing during processing. Then, the needle at the output end of the flat sewing machine is started, and the moving plate slides on the outer wall of the slide plate through the slide groove, making the moving plate's movement trajectory trapezoidal. At the same time, the moving plate drives the working groove to move along the outside of the needle at the output end of the flat sewing machine, thus completing the processing of the bag-pressing body.

[0007] 2. Beneficial effects: (1) Place the pressure bag opening body between the moving plate and the template, and then adjust the position of the pressure bag opening body so that the indicator plate points to the center of the surface of the pressure bag opening body, and the rear side of the pressure bag opening body contacts the front side of the embedding block, while the two sides of the pressure bag opening body are aligned with the moving plate, so as to ensure that the pressure bag opening body is placed in an accurate and neat position. Due to the reaction force of the support spring, it is convenient to drive the template to press the pressure bag opening body. At this time, the embedding groove is set on the outer wall of the embedding block to press the rear side of the pressure bag opening body and avoid skewing during the process. Then, the moving plate slides on the outer wall of the slide plate through the slide groove, so that the moving plate's movement trajectory is trapezoidal. At the same time, the moving plate drives the working groove to move along the outside of the needle at the output end of the flat sewing machine body, thus completing the processing of the pressure bag opening body.

[0008] Preferably, a support block is fixedly connected to the top of the fixed plate, and the bottom of the slide plate is fixedly connected to the top of the support block, so that the template can drive the guide plate to slide on the outer wall of the slide plate through the slide groove, while the guide plate slides on the outer wall of the support block through the moving groove.

[0009] Preferably, the bottom end of the guide plate is provided with a moving groove near the outer wall of the support block, and the support block is adapted to the inner wall of the moving groove. The inner wall of the sliding groove is connected to the inside of the moving groove, and the outer wall of the sliding plate is adapted to the inner wall of the sliding groove. Pulling the moving plate causes the moving plate to move the guide plate, so that the guide plate slides along the outer wall of the support block and the sliding plate respectively through the moving groove and the sliding groove, so that the moving trajectory of the moving plate is trapezoidal.

[0010] Preferably, there are two fixing rods arranged symmetrically, and each fixing rod has a baffle fixedly connected to its top. The template is slidably connected to the outer wall of the two fixing rods. Due to the action of the baffles, the template can only slide up and down within the height of the fixing rods.

[0011] Preferably, two support springs are provided, one end of which is fixedly connected to the top of the template and the other end is fixedly connected to the bottom of the baffle. Pulling the template upward causes it to slide on the outer wall of the fixed rod, while the template compresses the support springs. At this time, the distance between the template and the moving plate increases, which facilitates the placement of the bag opening body.

[0012] Preferably, the rear side of the bag-pressing opening body contacts the front side of the embedding block; when the embedding groove is fitted onto the outer wall of the embedding block, it facilitates the template to press the rear side of the bag-pressing opening body, avoiding skewing during the processing.

[0013] Preferably, one end of the indicator plate is located at the center of the surface of the bag-pressing opening body; the indicator plate points to the center of the surface of the bag-pressing opening body to ensure that the bag-pressing opening body is placed in an accurate and neat position.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-7 As shown, an auxiliary device for making the bag opening of a flat sewing machine includes a fixed plate 1, a flat sewing machine body 2 mounted on the top of the fixed plate 1, a sliding plate 5 at the top of the fixed plate 1, a support block 4 fixedly connected to the top of the fixed plate 1, a bottom end of the sliding plate 5 fixedly connected to the top end of the support block 4, a movable plate 3 slidably sleeved on the outer side of the sliding plate 5, a guide plate 6 fixedly connected to the bottom end of the movable plate 3, a groove 8 at the top of the guide plate 6 for sliding along the outer wall of the sliding plate 5, a movable groove 7 at the bottom end of the guide plate 6 near the outer wall of the support block 4, and the inner wall of the support block 4 is adapted to the inner wall of the movable groove 7, the inner wall of the groove 8 is connected to the inside of the movable groove 7, and the outer wall of the sliding plate 5 is connected to the inner wall of the groove 8. The moving plate 3 is fitted with a fixed rod 10 at its top. A support spring 12 is sleeved on the outer wall of the fixed rod 10, and a template 9 is slidably mounted on the outer wall of the fixed rod 10. The bag-pressing body 17 is placed between the moving plate 3 and the template 9. The needle at the output end of the flat sewing machine body 2 is started, pulling the moving plate 3, which causes the moving plate 3 to move the guide plate 6. The guide plate 6 slides along the outer wall of the support block 4 and the slide plate 5 through the moving groove 7 and the sliding groove 8, respectively, so that the moving trajectory of the moving plate 3 is trapezoidal. At the same time, the moving plate 3 drives the working groove 15 to move along the outside of the needle at the output end of the flat sewing machine body 2, thereby completing the processing of the bag-pressing body 17.

[0019] Support spring 12 is connected to template 9. Two fixing rods 10 are provided, symmetrically arranged. Baffles 11 are fixedly connected to the top of each fixing rod 10. Template 9 is slidably connected to the outer wall of the two fixing rods 10. Two support springs 12 are provided, one end of which is fixedly connected to the top of template 9, and the other end is fixedly connected to the bottom of baffle 11. The top and bottom of template 9 are provided with the same working groove 15, which is trapezoidal in shape. An embedding groove 13 is provided at the bottom of template 9. An indicator plate 14 is fixedly connected to the front of template 9. Three embedding blocks 16 are fixedly connected to the top of moving plate 3, and the three embedding blocks 16 are located on both sides and the middle of the top of moving plate 3, respectively. Several embedding blocks 16 are inserted into the embedding groove 13. The rear side of the bag opening body 17 contacts the front side of the embedding blocks 16. One end of the indicator plate 14 is located at... At the center of the surface of the bag-pressing body 17, pull the template 9 upward, causing the template 9 to slide on the outer wall of the fixed rod 10. At the same time, the template 9 drives the support spring 12 to compress, increasing the distance between the template 9 and the moving plate 3, thus facilitating the placement of the bag-pressing body 17. When placing the bag-pressing body 17, make the rear side of the bag-pressing body 17 contact the front side of the embedding block 16, and make the two sides of the bag-pressing body 17 aligned with the two sides of the moving plate 3, so that the indicator plate 14 points to the center of the surface of the bag-pressing body 17, ensuring that the bag-pressing body 17 is placed accurately and neatly. Release the template 9, and due to the reaction force of the support spring 12, make it easy to drive the template 9 to press the bag-pressing body 17. At this time, the embedding groove 13 is fitted on the outer wall of the embedding block 16, thus pressing the rear side of the bag-pressing body 17 and preventing skewing during processing.

[0020] As can be seen from the above, the specific implementation of this utility model is as follows: Pull the template 9 upward so that the template 9 slides on the outer wall of the fixed rod 10. At the same time, the template 9 drives the support spring 12 to compress. At this time, the distance between the template 9 and the moving plate 3 increases, so as to facilitate the placement of the bag opening body 17. When placing the bag opening body 17, the rear side of the bag opening body 17 contacts the front side of the embedding block 16, and the two sides of the bag opening body 17 are aligned with the two sides of the moving plate 3 respectively. In this way, the indicator plate 14 points to the center position of the surface of the bag opening body 17, ensuring that the bag opening body 17 is placed accurately and neatly. Release the template 9, and due to the reaction force of the support spring 12, it is convenient to drive the template 9 to press the bag opening body 17. At this time, the embedding groove 13 is sleeved on the outer wall of the embedding block 16, so as to press the rear side of the bag opening body 17 and avoid skewing during the processing. Next, the needle at the output end of the flat sewing machine body 2 is started, and the moving plate 3 is pulled, so that the moving plate 3 drives the guide plate 6 to move. Thus, the guide plate 6 slides along the outer wall of the support block 4 and the slide plate 5 through the moving groove 7 and the sliding groove 8 respectively. The moving plate 3 drives the working groove 15 to move along the outside of the needle at the output end of the flat sewing machine body 2. When the needle at the output end of the flat sewing machine body 2 moves from the left side to the right side of the working groove 15, the moving plate 3 drives the pressing bag opening body 17 to walk an approximately trapezoidal trajectory relative to the needle of the flat sewing machine body 17, thereby completing the sewing of multiple sides of the bag opening in one go, thus completing the processing of the pressing bag opening body 17.
