Description

Technical Field

[0001] This utility model relates to the field of electric sewing machine technology, specifically an electric sewing machine with an auxiliary positioning structure. Background Technology

[0002] In various fields such as garment manufacturing, home decoration, and handicraft production, electric sewing machines have become indispensable production tools due to their high efficiency, precision, and ease of operation. However, in practical applications, traditional electric sewing machines often encounter positioning difficulties when sewing complex patterns or fabrics requiring precise alignment. This is mainly because the fabric is prone to displacement during the sewing process due to uneven tension or improper operation, leading to deviations in the sewing results and affecting the quality and appearance of the product.

[0003] The reference patent, titled "An Electric Sewing Machine with an Auxiliary Positioning Structure" (Publication No. CN214655638U, Application Date 2021-01-19), describes a sewing machine that operates by passing material through two rollers. The drive motor is then activated, causing the output rod to rotate via a transmission belt, which in turn rotates the driven transmission wheel and connecting rod. The machine body then moves. When movement is required, the handle is rotated to move and position the material. After sewing is complete, a vacuum cleaner is activated, and the corrugated pipe is stretched to clean the surfaces of the worktable and operating table. A stabilizing rod prevents wobbling during operation. The overall structure is simple, achieving excellent positioning and improving work efficiency while preventing damage.

[0004] Based on the aforementioned patent, the existing technology can only quickly position the sewing material. However, when the electric sewing machine is used for actual processing, the sewing material is easily not straightened, which can lead to wrinkles and ultimately affect the subsequent sewing process. Therefore, this utility model provides an electric sewing machine with an auxiliary positioning structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electric sewing machine with an auxiliary positioning structure. This solves the problem that existing technologies can only quickly position the sewing material, but during actual processing, the material is easily not straightened, leading to wrinkles and ultimately affecting the subsequent sewing results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric sewing machine with an auxiliary positioning structure, comprising a machine body, a sleeve box fixedly installed on one side of the upper part of the machine body, and an auxiliary positioning structure provided on the machine body and the sleeve box, the auxiliary positioning structure comprising:

[0007] The pressing assembly is located on the upper part of the machine body. It includes a lifting sleeve that is slidably sleeved on the outer wall of the sleeve box. The lifting sleeve has base rods fixed on both sides. A sliding frame is slidably connected to the base rods. An elastic telescopic rod is fixed at the lower end of the sliding frame. A pressure roller is fixed at the end of the elastic telescopic rod. An extrusion plate is fixed on one side of the sliding frame. Trapezoidal blocks are fixed on both sides of the sleeve box so that when the extrusion plate moves down, it abuts against the trapezoidal blocks, thereby driving the sliding frame to move laterally. Reset parts are installed on the lower part of both sides of the base rod.

[0008] The rotating component is located on the upper part of the machine body and is used to drive the pressing component to move up and down.

[0009] Preferably, the elastic telescopic rod includes an insert rod fixed to the lower end of the base rod, and a rod sleeve is slidably sleeved on the lower end of the insert rod, and a spring is installed between the bottom wall of the rod sleeve and the insert rod.

[0010] Preferably, the reset part includes a fixing plate fixed to the lower part of one side of the base rod, and a compression spring is connected between the fixing plate and the insertion rod.

[0011] Preferably, the rotating assembly includes a protective box fixed to the upper part of the machine body, a rotating rod rotatably mounted on the side of the protective box, and a transmission screw rotatably mounted on the lower part of the protective box.

[0012] Preferably, a first bevel gear is fixed on the rotating rod, and a second bevel gear that meshes with the first bevel gear is fixed on the transmission screw. Both the first bevel gear and the second bevel gear are located inside the protective box.

[0013] Preferably, the lower end of the transmission screw is threadedly connected to a threaded sleeve, and a connecting rod connected to the lifting sleeve is fixed at the bottom of the threaded sleeve.

[0014] Beneficial effects

[0015] This invention provides an electric sewing machine with an auxiliary positioning structure. Compared with the prior art, it has the following advantages:

[0016] (1) The electric sewing machine with auxiliary positioning structure is designed with a pressing and spreading component. When the rotating component drives the lifting sleeve to descend, the base rod and slide frame move down accordingly. Then the elastic telescopic rod begins to compress, the spring is stressed, and the pressure roller gradually contacts and presses down the sewing material. As the lifting sleeve continues to descend, the extrusion plate contacts and is squeezed by the trapezoidal block. Due to the inclined design of the trapezoidal block, the extrusion plate drives the slide frame to move laterally along the base rod, further stretching the sewing material laterally. It can straighten the sewing material while positioning it, avoiding wrinkles in the sewing material that would affect the subsequent sewing process.

[0017] (2) The electric sewing machine with auxiliary positioning structure drives the first bevel gear to rotate through the rotation of the rotating rod. The first bevel gear meshes with the second bevel gear, so the second bevel gear also rotates, which in turn drives the transmission screw to rotate. This design realizes the conversion of vertical rotational force into horizontal linear movement force. The rotation of the transmission screw drives the threaded sleeve to move up and down. The bottom of the threaded sleeve is connected to the lifting sleeve through the connecting rod. Therefore, the movement of the threaded sleeve is directly converted into the lifting action of the lifting sleeve, which drives the lifting sleeve to descend. The overall transmission efficiency is high and the operation is convenient. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4This utility model provides a technical solution: an electric sewing machine with an auxiliary positioning structure, including a machine body 1, a housing 2 fixedly installed on one side of the upper part of the machine body 1, and an auxiliary positioning structure provided on the machine body 1 and the housing 2. The auxiliary positioning structure includes: a pressing and spreading component 3, which is set on the upper part of the machine body 1, including a lifting sleeve 31 that is slidably sleeved on the outer wall of the housing 2, and base rods 32 fixed on both sides of the lifting sleeve 31. A sliding frame 33 is slidably connected to the base rods 32, and an elastic telescopic rod 34 is fixed at the lower end of the sliding frame 33. A pressure roller 35 is fixed at the end of the elastic telescopic rod 34. A pressing plate 36 is fixed on one side of the sliding frame 33, and trapezoidal blocks 37 are fixed on both sides of the housing 2, so that when the pressing plate 36 moves down, it abuts against the trapezoidal blocks 37, thereby driving the sliding frame 33 to move laterally. A reset part 38 is installed on the lower part of both sides of the base rod 32; and a rotating component 4, which is set on the upper part of the machine body 1 and is used to drive the pressing and spreading component 3 to move up and down.

[0025] In this embodiment, the elastic telescopic rod 34 includes an insert rod 342 fixed to the lower end of the base rod 32, and a rod sleeve 341 is slidably sleeved on the lower end of the insert rod 342. A spring 343 is installed between the inner bottom wall of the rod sleeve 341 and the insert rod 342. The elastic telescopic rod 34 has elastic telescopic properties, so that while pressing down on the sewing material, it can be expanded laterally in conjunction with other components.

[0026] In this embodiment, the reset part 38 includes a fixing piece 381 fixed to the lower part of one side of the base rod 32, and a compression spring 382 is connected between the fixing piece 381 and the insertion rod 342; the lifting sleeve 31 drives the base rod 32 and the sliding frame 33 to rise, and the elastic telescopic rod 34 returns to its original position under the action of the spring 343, which is convenient for the next use.

[0027] In this embodiment, the rotating assembly 4 includes a protective box 41 fixed to the upper part of the body 1. A rotating rod 42 is rotatably mounted on the side of the protective box 41, and a transmission screw 43 is rotatably mounted on the lower part of the protective box 41. A first bevel gear 44 is fixed on the rotating rod 42, and a second bevel gear 45 that meshes with the first bevel gear 44 is fixed on the transmission screw 43. Both the first bevel gear 44 and the second bevel gear 45 are located inside the protective box 41. A threaded sleeve 46 is threadedly connected to the lower end of the transmission screw 43, and a connecting rod 47 connected to the lifting sleeve 31 is fixed to the bottom of the threaded sleeve 46. By rotating the rotating rod 42, the first bevel gear 44 on it rotates accordingly. The first bevel gear 44 meshes with the second bevel gear 45, so the second bevel gear 45 also rotates, thereby driving the transmission screw 43 to rotate. This design realizes the conversion of vertical rotational force into horizontal linear movement force. The rotation of the transmission screw 43 drives the threaded sleeve 46 to move up and down, and the movement of the threaded sleeve 46 is directly converted into the lifting action of the lifting sleeve 31.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, rotating the rotating rod 42 in the rotating assembly 4 causes the first bevel gear 44 on it to rotate as well. The first bevel gear 44 meshes with the second bevel gear 45, causing the second bevel gear 45 to rotate as well, which in turn drives the transmission screw 43 to rotate. This design converts vertical rotational force into horizontal linear movement force. The rotation of the transmission screw 43 causes the threaded sleeve 46 to move up and down. The bottom of the threaded sleeve 46 is connected to the lifting sleeve 31 via a connecting rod 47. Therefore, the movement of the threaded sleeve 46 is directly converted into the movement of the lifting sleeve 31. When the lifting action of 1 causes the lifting sleeve 31 to descend, the base rod 32 and the sliding frame 33 move down accordingly. Then the elastic telescopic rod 34 begins to compress, the spring 343 is stressed, and the pressure roller 35 gradually contacts and presses down on the sewing material. As the lifting sleeve 31 continues to descend, the extrusion plate 36 contacts and is squeezed by the trapezoidal block 37. Due to the inclined design of the trapezoidal block 37, the extrusion plate 36 drives the sliding frame 33 to move laterally along the base rod 32, further stretching the sewing material laterally. Finally, the sewing needle assembled on the sleeve 2 sews the product.

[0030] Furthermore, when the rotating component 4 stops descending and reverses direction to rise, the lifting sleeve 31 drives the base rod 32 and the slide frame 33 to rise. The elastic telescopic rod 34 returns to its original position under the action of the spring 343, and the pressure roller 35 leaves the sewing material. At the same time, the compression spring 382 of the reset part 38 causes the slide frame 33 to move in the opposite direction along the base rod 32 through the fixing plate 381 and the insert rod 342, returning to the initial position.
