Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, specifically to a double-sewing sewing machine mold. Background Technology

[0002] In the field of sewing machine technology, double-sewing technology has a wide range of applications. As a key auxiliary device designed for this technology, the double-sewing machine mold usually needs to work in conjunction with equipment such as double-needle sewing machines to achieve efficient and precise sewing operations.

[0003] Currently, there are publicly available examples of automatic sewing machine sewing devices and their molds in the prior art, such as the technical solution disclosed in publication number CN216585533U. The automatic sewing machine sewing device and its mold in this solution mainly consist of a base plate, a pressure plate, and sewing holes. The pressure plate is fixedly connected to one side of the top of the base plate via a fastener. Multiple sets of sewing holes are formed on the upper surfaces of both the base plate and the pressure plate. Three sets of limiting blocks are also provided on the upper surface of the base plate, two sets distributed on both sides of the base plate, and the other set located at one end of the sewing holes and away from the fastener. In practical applications, this mold can quickly install the fabric, then be snapped onto a T-shaped plate. A moving mechanism then drives the mold to move in the front-back and left-right directions, enabling the sewing machine to sew the fabric edges. This design reduces labor intensity, improves production efficiency, ensures consistent production quality, and shortens the preparation cycle by using two sets of molds alternately, further improving production efficiency.

[0004] However, in existing technologies of this type, when one side is sewn and it's time to switch to the next side, the motor needs to be started. The motor drives the lead screw to rotate, which in turn moves the T-shaped plate along the inner wall of the groove. The T-shaped plate then moves the mold to the next side for sewing. During this process, ensuring the precise alignment of the needle at the bottom of the sewing machine with the sewing hole is crucial. However, existing technologies lack effective alignment aids and rely mainly on manual judgment of whether the needle and sewing hole align. Due to the significant errors in manual judgment, when the needle fails to align accurately with the sewing hole, it may come into contact with the upper part of the mold during sewing, causing damage. Furthermore, to adjust the alignment, the operator needs to constantly start and stop the motor, which is not only cumbersome but also negatively impacts the motor's lifespan. Utility Model Content

[0005] The purpose of this invention is to provide a double-seam sewing machine mold to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-stitch sewing machine mold, including a worktable, with two sewing needles connected to the upper end of the worktable via a mounting base, a mold body at the bottom end of each sewing needle, and several sewing holes at the upper end of the mold body. A hydraulic cylinder is fixedly connected to the upper end of the worktable, and a fixed plate is fixedly connected to the output end of the hydraulic cylinder. A mounting groove is provided on one side of the fixed plate, and a lead screw is rotatably connected within the mounting groove. A movable plate is threadedly connected to the outer side of the lead screw, and one side of the movable plate is engaged with one side of the mold body. Side plates are provided on both sides of the mold body, and both side plates are fixed to the bottom end of the movable plate. A mounting rod is fixedly connected to the outer side of one of the side plates, and several slots corresponding to the sewing holes are provided at the upper end of the mounting rod. A connecting plate is fixedly connected to one side of the mounting base. An indicator component is provided at the bottom of the connecting plate. The indicator component includes two rods. The upper ends of the two rods are movably sleeved with the connecting plate. The lower ends of the two rods are movably inserted into two slots respectively. A fixing block is fixedly sleeved on the outside of the two rods. Two springs are fixedly connected between the fixing block and the connecting plate. The two springs are respectively sleeved on the outside of the two rods.

[0007] Preferably, guide blocks are fixedly connected to the bottom ends of both sides of the mold body, and guide grooves matching the guide blocks are provided on the side of the two side plates near the mold body. The two guide blocks are slidably connected to the two guide grooves respectively.

[0008] Preferably, the two insertion rods correspond to the two suture needles respectively, and the distance between the two suture needles is equal to the distance between two adjacent suture holes.

[0009] Preferably, the bottom ends of both insertion rods are hemispherical, and the plurality of slots are matched with the bottom ends of the insertion rods.

[0010] Preferably, the thickness of the movable plate matches the thickness of the mounting groove.

[0011] Compared with existing technologies, by setting slots on the mounting rod corresponding to the sewing holes, and since the mounting rod is fixed to the side plate, it moves with the mold body, ensuring that several slots always correspond to several sewing holes. The insertion rod corresponds to the sewing needle. When the mold moves to align the sewing hole with the sewing needle, the insertion rod can accurately insert into the corresponding slot, providing workers with intuitive alignment instructions. This greatly improves alignment accuracy, effectively avoids needle damage caused by misalignment, extends the service life of the sewing needle, and reduces equipment maintenance costs.

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 The present invention provides the following technical solution: Example 1: A double-stitch sewing machine mold includes a worktable 1. Two sewing needles 2 are connected to the upper end of the worktable 1 via a mounting base. A mold body 3 is located at the bottom of each sewing needle 2. The upper end of the mold body 3 has several sewing holes 4. A hydraulic cylinder 9 is fixedly connected to the upper end of the worktable 1. A fixed plate 8 is fixedly connected to the output end of the hydraulic cylinder 9. A mounting groove 6 is provided on one side of the fixed plate 8. A lead screw 10 is rotatably connected within the mounting groove 6. A movable plate 7 is threadedly connected to the outer side of the lead screw 10. One side of the movable plate 7 engages with one side of the mold body 3. Side plates 12 are provided on both sides of the mold body 3. Both side plates 12 are fixed to the bottom of the movable plate 7. A mounting rod 13 is fixedly connected to the outer side of one of the side plates 12. The upper end of the mounting rod 13 has several slots 14 corresponding to the sewing holes 4. The mounting base is located on one side. A connecting plate 11 is fixedly connected, and an indicator component 5 is provided at the bottom of the connecting plate 11. The indicator component 5 includes two insert rods 51. The upper ends of the two insert rods 51 are movably sleeved with the connecting plate 11, and the lower ends of the two insert rods 51 are movably inserted into two slots 14 respectively. A fixing block 52 is fixedly sleeved on the outside of the two insert rods 51. Two springs 53 are fixedly connected between the fixing block 52 and the connecting plate 11. The two springs 53 are respectively sleeved on the outside of the two insert rods 51. When the mold moves to align the sewing hole 4 with the sewing needle 2, the insert rods 51 can accurately insert into the corresponding slots 14, providing the staff with intuitive alignment indication, greatly improving the alignment accuracy, effectively avoiding damage to the sewing needle 2 caused by misalignment, extending the service life of the sewing needle 2, and reducing equipment maintenance costs. The two insert rods 51 correspond to the two suture needles 2 respectively. The distance between the two suture needles 2 is equal to the distance between two adjacent suture holes 4, ensuring that when the insert rods 51 are inserted into the slots 14, the suture needles 2 are accurately aligned with the suture holes 4. The bottom ends of both insert rods 51 are hemispherical, and several slots 14 are matched with the bottom ends of insert rods 51, making it easy for the bottom ends of insert rods 51 to be inserted into and removed from slots 14; The thickness of the movable plate 7 matches the thickness of the mounting groove 6, ensuring that the movable plate 7 will move stably within the mounting groove 6 when the screw 10 is rotated.

[0016] In use, the fabric is placed into the mold body 3, as described in detail in the prior art. The hydraulic cylinder 9 pushes the fixed plate 8, the moving plate 7, and the mold body 3 to move. During this process, the sewing needle 2 is repeatedly inserted into the sewing hole 4 to sew the fabric. When one side is sewn and it is necessary to switch to the next side to continue sewing, the operator manually rotates the screw 10. The screw 10 rotates in the mounting groove 6. Since the moving plate 7 is threadedly connected to the screw 10, and the thickness of the moving plate 7 matches the thickness of the mounting groove 6, the rotation of the screw 10 will drive the moving plate 7 to move smoothly along the mounting groove 6. One side of the moving plate 7 is engaged with the mold body 3, and the two side plates 12 are fixed to the bottom of the moving plate 7. Therefore, the moving plate 7 will drive the mold body 3 and the side plates 12 to move together. During the movement of body 3, mounting rod 13 moves accordingly. Since several slots 14 always correspond to several sewing holes 4, and two insert rods 51 correspond to two sewing needles 2 respectively, when the mold body 3 moves to align the sewing hole 4 with the sewing needle 2, the insert rod 51 will accurately insert into the corresponding slot 14 under the action of spring 53. The operator can visually judge whether the sewing needle 2 and the sewing hole 4 are accurately aligned by observing whether the insert rod 51 is inserted into the slot 14. If the insert rod 51 is not inserted into the slot 14, it means that the alignment is inaccurate. At this time, the screw 10 can be finely adjusted until the insert rod 51 is accurately inserted into the slot 14. Then the sewing operation of the next side can be carried out. This effectively avoids damage to the sewing needle 2 caused by misalignment, extends the service life of the sewing needle 2, and reduces equipment maintenance costs.

[0017] Example 2, the technical solution of this example, which differs from Example 1, further includes: guide blocks 16 are fixedly connected to the bottom ends of both sides of the mold body 3, and guide grooves 15 matching the guide blocks 16 are provided on the side of the two side plates 12 near the mold body 3. The two guide blocks 16 are slidably connected to the two guide grooves 15 respectively. Through the slidable connection between the guide blocks 16 and the guide grooves 15, it is convenient to quickly position the mold body 3, which not only ensures the stability of the mold body 3, but also ensures that the several stitching holes 4 at the upper end of the mold body 3 correspond to the several slots 14 on the mounting rod 13.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
