Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, and specifically to a sewing machine with a novel structure. Background Technology

[0002] Blind seam reinforcement, also known as seam trimming, is a process in garment manufacturing where, after two layers of fabric are sewn together, the seam needs to be reinforced to improve its appearance. Currently, blind seam reinforcement is primarily done manually along the seam, which is inefficient, labor-intensive, and susceptible to human error, making it difficult to guarantee the quality of the reinforcement.

[0003] For example, Chinese utility model patent number CN202123059296.9 discloses a garment sewing machine, which includes a base, a column vertically mounted on the base, a crossbeam horizontally mounted on the upper end of the column, a pressing component at the front end of the crossbeam, and a support component correspondingly mounted below the pressing component. The support component includes a lower fixed seat, a lower front friction wheel pivotally mounted at the front end of the lower fixed seat, which is located below the front upper conveyor wheel; and lower rear friction wheels pivotally mounted on both sides of the rear end of the lower fixed seat, which are located below the rear roller seat. A fixing frame is horizontally mounted on the base, and the front end of the fixing frame has a fixing plate. The lower fixed seat is fixedly mounted on the fixing plate, and the garment can also be guided by the fixing frame when moving.

[0004] For example, Chinese utility model patent CN202122237067.5 discloses a blind seam thread pulling machine, which includes a base, a feeding base plate, a swing arm, a swing driver, a blind seam thread pulling assembly, a blind seam thread pulling drive mechanism, and two bottom feeding wheels. The middle part of the swing arm is rotatably connected to the base. The blind seam thread pulling assembly is disposed at one end of the swing arm and located above the feeding base plate. The other end of the swing arm is driven and connected to the output end of the swing driver. The feeding end of the feeding base plate is provided with a material guiding structure. The two bottom feeding wheels are rotatably connected to the discharge end of the feeding base plate, and the two bottom feeding wheels and the material guiding structure are arranged in a Y-shape. The blind seam thread pulling machine also includes a fixed arm. One end of the fixed arm is fixedly connected to the base plate, and the other end of the fixed arm is connected to the feeding base plate. In this structural design, the fixed arm supports the feeding base plate and is suspended in the air, which facilitates the operator to place the fabric between the blind seam thread pulling assembly and the feeding base plate.

[0005] In the actual sewing process of the above-mentioned prior art, after the fabric is placed on the feed end of the sewing base, the rotating downward feeding component cooperates with the sewing base to transport the fabric, so that the fabric moves toward the two sewing feed rollers. With the cooperation of the downward feeding component and the two sewing feed rollers respectively, the two sides of the fabric pass through the two sewing feed rollers respectively. The two sewing feed rollers pull the two sides of the fabric outward to realize the sewing of the fabric.

[0006] However, during the continuous feeding and sewing of the fabric, it is necessary to hold both sides of the fabric with both hands and keep it on both sides of the fixed frame (i.e., fixed arm) to guide the subsequent feeding of the fabric and prevent the fabric from shifting position. Therefore, the operation is inconvenient and not suitable for long-term work. Utility Model Content

[0007] The purpose of this invention is to provide a sewing machine with a novel structure, which solves the problem of inconvenient operation through an auxiliary feeding component.

[0008] The purpose of this utility model is achieved as follows: A sewing machine with a novel structure includes a base, a column mounted on the base, a crossbeam mounted on the column, a motor power source for driving the crossbeam to rotate at the rear end of the crossbeam, a fixing frame mounted horizontally on the base, a sewing feed assembly between the fixing frame and the front end of the crossbeam, a lower auxiliary feed assembly inside the fixing frame, and an upper auxiliary feed assembly at the lower end of the crossbeam that works in conjunction with the lower auxiliary feed assembly, with a gap between the upper and lower auxiliary feed assemblies for the fabric to pass through.

[0009] Preferably, the upper end face of the fixed frame is provided with an extended operating platform, and the extended operating platform is provided with a through hole one for the lower auxiliary feeding component to extend and a through hole two for the seam-opening feeding component to extend, and the front end of the extended operating platform is formed with an arc-shaped feeding part.

[0010] Preferably, the lower auxiliary feeding assembly includes a second motor power source and two lower driven feeding wheels. The two lower driven feeding wheels are respectively arranged at the front and rear ends of the fixed frame, the second motor power source is arranged at the middle of the fixed frame, the output end of the second motor power source is equipped with a drive wheel, and a feeding synchronous belt is arranged between the lower driven feeding wheels and the drive wheel.

[0011] Preferably, a lower rotating shaft is provided inside the lower driven feeding wheel, and a strip-shaped mounting hole is provided on the side of the fixing frame, with the outer end of the lower rotating shaft adjustablely positioned inside the strip-shaped mounting hole.

[0012] Preferably, the upper auxiliary feeding assembly includes an upper pressure block connected to the crossbeam, an upper pressure plate is provided on the lower end face of the upper pressure block, side plates are provided on both sides of the upper pressure plate, and a plurality of upper driven feeding wheels are rotatably arranged between the two side plates.

[0013] Preferably, the first motor power source is mounted on the base, and a lifting eccentric wheel is installed at the output end of the first motor power source. A lifting connecting rod is installed on the outer periphery of the lifting eccentric wheel, and the other end of the lifting connecting rod is connected to the rear end of the crossbeam.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] This invention, through the design of the auxiliary feeding component, allows the fabric to continue to be conveyed by the upper and lower auxiliary feeding components after it has passed through the sewing feed component. This guides the subsequent conveying of the fabric, prevents the fabric from shifting position, and eliminates the need for manual feeding, thus preventing the fabric from accumulating in this area.

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-5As shown, a novel sewing machine includes a base 1, a column 2 mounted on the base 1, a crossbeam 3 mounted on the column 2, a motor power source 4 for driving the crossbeam 3 to rotate at its rear end, a fixing frame 5 horizontally mounted on the base 1, a sewing feed assembly 6 between the fixing frame 5 and the front end of the crossbeam 3, a lower auxiliary feed assembly 7 inside the fixing frame 5, and an upper auxiliary feed assembly 8 at the lower end of the crossbeam 3 for use with the lower auxiliary feed assembly 7, with a gap between the upper auxiliary feed assembly 8 and the lower auxiliary feed assembly 7 for the fabric to pass through.

[0024] This invention, through the design of the auxiliary feeding component, enables the fabric to continue to be conveyed by the upper and lower auxiliary feeding components 7 after it has passed through the sewing feed component 6. This guides the subsequent conveying of the fabric, prevents the fabric from shifting position, and eliminates the need for manual feeding, thus preventing the fabric from accumulating in this area. This facilitates continuous sewing work, is simple and convenient to operate, and is suitable for long-term work.

[0025] Combination Figure 1 and Figure 2 The upper surface of the fixed frame 5 is provided with an extended operating platform 9. The extended operating platform 9 is provided with a through hole 10 for the lower auxiliary feeding component 7 to extend and a through hole 11 for the sewing feed component 6 to extend. The front end of the extended operating platform 9 is formed with an arc-shaped feeding part 12. This technical solution increases the convenience of operation through the design of the extended operating platform 9. In actual operation, the position of the fabric can be adjusted by placing both hands on the upper end of the platform. Compared with the fixed frame in the prior art, which requires both hands to be suspended on both sides of the fixed frame for operation, this is more labor-saving and reduces the difficulty of operation.

[0026] See details Figure 3 The lower auxiliary feeding assembly 7 includes a second motor power source 13 and two lower driven feeding wheels 14. The two lower driven feeding wheels 14 are respectively arranged at the front and rear ends of the fixed frame 5. The second motor power source 13 is arranged at the middle end of the fixed frame 5. The output end of the second motor power source 13 is equipped with a drive wheel 15. A feeding timing belt 16 is arranged between the lower driven feeding wheels 14 and the drive wheels 15.

[0027] The lower driven feed wheel 14 is provided with a lower rotating shaft 17. The side of the fixed frame 5 is provided with a strip-shaped mounting hole 18. The outer end of the lower rotating shaft 17 is adjustablely set in the strip-shaped mounting hole 18 so as to adjust the tension of the feeding timing belt 16.

[0028] See details Figure 4The upper auxiliary feeding assembly 8 includes an upper pressure block 19 connected to the crossbeam 3. An upper pressure plate 20 is provided on the lower end face of the upper pressure block 19. Side plates 21 are provided on both sides of the upper pressure plate 20. Several upper driven feeding wheels 22 are rotatably arranged between the two side plates 21. In the actual conveying process, the upper driven feeding wheels 22 and the feeding synchronous belt 16 abut against the upper and lower end faces of the fabric respectively. The feeding synchronous belt 16 is driven by the motor power source 2 13 below, so that the fabric is transported between the upper driven feeding wheels 22 and the feeding synchronous belt 16.

[0029] See details Figure 5 The motor power source 4 is mounted on the base 1. A lifting eccentric wheel 23 is installed at the output end of the motor power source 4. A lifting connecting rod 24 is installed on the outer periphery of the lifting eccentric wheel 23. The other end of the lifting connecting rod 24 is connected to the rear end of the crossbeam 3. The rotation of the motor shaft drives the lifting eccentric wheel 23 to rotate, thereby driving the crossbeam 3 to rotate through the lifting connecting rod 24, raising or lowering the front end position of the crossbeam 3, so as to put the fabric into the seam feeding assembly 6. Compared with the prior art that uses a cylinder as a power source and cannot adjust the lifting height, this technical solution can control the lifting height of the crossbeam by the rotation angle of the motor, thus being suitable for fabrics of different thicknesses. Moreover, the lifting process is smoother and less prone to shaking.
