Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to a sewing machine push plate. Background Technology

[0002] The sewing machine pusher plate, a key functional component of the sewing machine, is mainly used to push the fabric during the sewing process, ensuring that the fabric moves evenly in a set direction and speed to guarantee neat and beautiful stitches. Its development is closely related to the increasing demand for automation and precision in sewing processes.

[0003] Currently, one type of sewing machine push plate in existing technology uses traditional fixing methods, such as bolts and slots, which require tools to tighten or manual alignment. Replacing a push plate on a single machine takes 10-15 minutes and requires regular inspection and tightening, affecting production efficiency. On the other hand, fixing methods such as using gaskets increase assembly complexity and are difficult to adapt to the rapid switching between different sewing machine models. Utility Model Content

[0004] The purpose of this invention is to solve the problems of traditional fixing methods in the prior art, such as bolts and slots, which require tools to tighten or manual alignment. Changing the push plate on a single machine takes 10-15 minutes and requires regular inspection and tightening, affecting production efficiency. As for fixing methods such as gaskets, they increase assembly complexity and are difficult to adapt to the problem of rapid switching between different sewing machine models. Therefore, this invention proposes a sewing machine push plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sewing machine push plate, comprising a push plate body, wherein slots are provided on both sides of the bottom end of the push plate body, and neodymium iron boron permanent magnets are placed in both slots; an inner cavity is provided in the push plate body between the two slots, and a bidirectional screw is rotatably connected to the inner wall of the inner cavity; movable plates are threadedly connected to both ends of the outer wall of the bidirectional screw; limit posts are slidably connected to both ends of the two movable plates; an insert block is fixed to one end of the two movable plates facing away from each other; the end of the insert block away from the movable plate passes through the neodymium iron boron permanent magnet and is inserted into the push plate body.

[0006] Preferably, a first bevel gear is fixed on the outer wall of the bidirectional screw, the first bevel gear is meshed with a second bevel gear, a connecting column is fixed at one end of the second bevel gear, and the end of the connecting column away from the second bevel gear passes through the push plate body and is fixed with a rotating plate.

[0007] Preferably, the rear end of the push plate body has an opening, the rotating plate is disposed in the opening, and the end of the rotating plate away from the connecting column has a hexagonal groove.

[0008] Preferably, a rubber block is installed on the inner wall of the opening, and one end of the rubber block abuts against the rotating plate.

[0009] Preferably, a damping ring is installed inside the push plate body, and the connecting column is rotatably connected to the push plate body through the damping ring.

[0010] Preferably, both ends of the limiting post are fixed to the inner wall of the inner cavity, and the push plate body has a connecting cavity on both sides of the two slots that matches the insert block.

[0011] Preferably, a scale groove is provided on one side of the top of the push plate body.

[0012] Preferably, the push plate body has a connecting groove inside.

[0013] Preferably, baffles are fixed on both sides of the outer wall of the bidirectional screw.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, the device uses neodymium iron boron permanent magnets instead of traditional bolts or washers for fixing. The connection between the push plate body and the sewing machine body is achieved through the attraction force of the neodymium iron boron permanent magnets. This eliminates the need for cumbersome tightening or plugging operations of traditional mechanical connectors such as bolts and buckles. Furthermore, since the neodymium iron boron permanent magnets have no moving mechanical parts, they avoid the loosening or fatigue failure of traditional buckles, springs, and other structures due to long-term vibration. Furthermore, this device allows the user to rotate the rotating plate, which in turn drives the connecting column to rotate, thereby driving the second bevel gear to rotate, which in turn drives the first bevel gear meshing with it to rotate, which in turn drives the bidirectional screw to rotate. This causes the two moving plates to move towards or away from each other under the limitation of the limiting column, thereby driving the two sets of insert blocks to move towards or away from each other. When the two sets of insert blocks move towards each other, they will pass through the two neodymium iron boron permanent magnets and insert them into the push plate body, enabling the two neodymium iron boron permanent magnets to be snapped into place. When the two insert blocks move towards each other and retract into the inner cavity, they no longer snap into place the two neodymium iron boron permanent magnets, allowing the user to remove and replace the two neodymium iron boron permanent magnets at any time, making it more practical.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, such as Figure 1-5 As shown, this utility model provides a sewing machine push plate, including a push plate body 1. The bottom end of the push plate body 1 has slots 4 on both sides. Neodymium iron boron permanent magnets 3 are placed in both slots 4. An inner cavity 5 is opened in the push plate body 1 between the two slots 4. A bidirectional screw 6 is rotatably connected to the inner wall of the inner cavity 5. The outer ends of the bidirectional screw 6 are threaded with movable plates 7. The two ends of the two movable plates 7 are slidably connected with limit posts 8. An insert block 10 is fixed at the opposite end of the two movable plates 7. The end of the insert block 10 away from the movable plate 7 passes through the neodymium iron boron permanent magnet 3 and is inserted into the push plate body 1.

[0025] The overall effect of Embodiment 1 is that this device uses neodymium iron boron permanent magnets 3 instead of traditional bolts or washers for fixing. The connection between the push plate body 1 and the sewing machine body is achieved through the attraction force of the neodymium iron boron permanent magnets 3, eliminating the need for cumbersome tightening or plugging operations of traditional bolts, buckles, and other mechanical connectors. Furthermore, since the neodymium iron boron permanent magnets 3 have no moving mechanical parts, they avoid the loosening or fatigue failure of traditional buckles, springs, and other structures due to long-term vibration. The rotation of the bidirectional screw 6 causes the two moving plates 7 to be in the limit position. The column 8 moves in opposite directions or to the opposite direction, thereby driving the two sets of insert blocks 10 to move in opposite directions or to the opposite direction. When the two sets of insert blocks 10 move in opposite directions, they will pass through the two neodymium iron boron permanent magnets 3 and be inserted into the push plate body 1, which can snap the two neodymium iron boron permanent magnets 3 into place. When the two insert blocks 10 move in opposite directions and retract into the inner cavity 5, they no longer snap the two neodymium iron boron permanent magnets 3 into place. Users can disassemble the two neodymium iron boron permanent magnets 3 at any time and replace them, making them more practical.

[0026] Example 2, as Figure 1-5 As shown, a first bevel gear 13 is fixed to the outer wall of the bidirectional screw 6. The first bevel gear 13 is meshed with a second bevel gear 14. A connecting post 15 is fixed to one end of the second bevel gear 14. The end of the connecting post 15 away from the second bevel gear 14 passes through the push plate body 1 and is fixed with a rotating plate 16. An opening 19 is opened at the rear end of the push plate body 1. The rotating plate 16 is located in the opening 19. A hexagonal groove 17 is opened at the end of the rotating plate 16 away from the connecting post 15. A rubber seal is installed on the inner wall of the opening 19. Block 20, one end of rubber block 20 abuts against rotating plate 16, damping ring 18 is installed in push plate body 1, connecting column 15 is rotatably connected to push plate body 1 through damping ring 18, both ends of limiting column 8 are fixed to inner wall of inner cavity 5, connecting cavity 11 matching the insert block 10 is opened on both sides of the two slots 4 in push plate body 1, scale groove 21 is opened on one side of the top of push plate body 1, connecting groove 2 is opened in push plate body 1, baffle 12 is fixed on both sides of the outer wall of bidirectional screw 6.

[0027] The effect achieved by the entire embodiment 2 is that by rotating the rotating plate 16, the connecting column 15 rotates, thereby driving the second bevel gear 14 to rotate, driving the first bevel gear 13 meshing with it to rotate, driving the bidirectional screw 6 to rotate, causing the two moving plates 7 to move towards or away from each other under the limitation of the limiting column 8, thereby driving the two sets of insert blocks 10 to move towards or away from each other. When the two sets of insert blocks 10 move towards each other, they will pass through the two neodymium iron boron permanent magnets 3 and be inserted into the push plate body 1, which can snap the two neodymium iron boron permanent magnets 3 into place. When the two insert blocks 10 move towards each other and retract into the inner cavity 5, they no longer snap the two neodymium iron boron permanent magnets 3 into place, and the user can move freely. The two neodymium iron boron permanent magnets 3 can be disassembled and replaced, making it more practical. The damping ring 18 increases the damping of the connecting column 15 rotation, and the rubber block 20 increases the damping of the rotating plate 16 rotation, effectively preventing it from rotating on its own. The baffle 12 prevents the two moving plates 7 from moving to the unthreaded part of the outer wall of the bidirectional screw 6 when the user rotates it, thus improving stability. The hexagonal groove 17 allows the user to rotate the rotating plate 16 with the help of an external hexagonal wrench when it is inconvenient to rotate it. The scale groove 21 allows the user to observe the distance of the fabric sewing, making it more practical.

[0028] Working principle: When in use, this device uses neodymium iron boron permanent magnets 3 instead of traditional bolts or washers for fixing. The connection between the push plate body 1 and the sewing machine body is achieved by the attraction force of the neodymium iron boron permanent magnets 3. There is no need for the cumbersome tightening or plugging and unplugging operations of traditional bolts, buckles and other mechanical connectors. Moreover, the neodymium iron boron permanent magnets 3 have no mechanical moving parts, avoiding the loosening or fatigue failure of traditional buckles, springs and other structures due to long-term vibration. Furthermore, by rotating the rotating plate 16, the user drives the connecting column 15 to rotate, which in turn drives the second bevel gear 14 to rotate, which in turn drives the first bevel gear 13 to rotate, which in turn drives the bidirectional screw 6 to rotate. This causes the two moving plates 7 to move towards or away from each other under the limitation of the limiting column 8, thereby driving the two sets of insert blocks 10 to move towards or away from each other. When the two sets of insert blocks 10 move towards each other, they will pass through the two neodymium iron boron permanent magnets 3 and be inserted into the push plate body 1, which can snap the two neodymium iron boron permanent magnets 3 into place. When the two insert blocks 10 move towards each other and retract into the inner cavity 5, they no longer snap the two neodymium iron boron permanent magnets 3 into place. The user can remove the two neodymium iron boron permanent magnets 3 at any time and replace them, making it more practical.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
