[0001] This utility model relates to the field of sewing machines, specifically a sewing machine with a fabric pressing device. Background Technology

[0002] A sewing machine with a fabric presser is a type of sewing equipment that adds a fabric presser to a traditional sewing machine. The function of this presser is to compress and hold the fabric during the sewing process, preventing it from shifting or wrinkling, thus ensuring smooth, aesthetically pleasing stitches and improving sewing quality and efficiency. This type of sewing machine is particularly suitable for sewing thicker or slippery fabrics, as well as for applications requiring high-precision sewing.

[0003] Currently, sewing machines equipped with a fabric pressing device mainly use one or two spreading wheels and one tensioning wheel to press the fabric firmly through a pressing belt at the bottom of the two spreading wheels to ensure the stability of the fabric during the sewing process. However, in actual use, the operator needs to repeatedly adjust the two spreading wheels horizontally before using the pressing device to ensure that they are in the correct position. If they are not adjusted properly, it may cause uneven pressing of the fabric, or even wrinkles or displacement, thus affecting the sewing effect and quality. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a sewing machine with a fabric pressing device to solve the technical problems of cumbersome horizontal adjustment of the spreading wheel in sewing machines with fabric pressing devices, which can easily lead to uneven fabric pressing and affect sewing effect and quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sewing machine with a fabric pressing device, comprising a sewing machine and a fabric pressing mechanism, wherein the fabric pressing mechanism comprises a first clamp, a second clamp, a first connecting rod and a third connecting rod, wherein an installation groove is provided on one side of the first connecting rod and the third connecting rod, and a correction mechanism is provided on one side of the installation groove;

[0006] The correction mechanism includes a photoelectric sensor and a receiver. The photoelectric sensor is located on one side of the third link, and the receiver is located on one side of the first link. Both the photoelectric sensor and the receiver have screws at their rear ends, and the screws pass through the mounting groove and are fixedly connected by tightening nuts.

[0007] The photoelectric sensor has a transmitter head at its front end, and a transmitter port on one side of the transmitter head. The receiver has a receiver head at its front end, and a receiver port on one side of the receiver head.

[0008] By adopting the above technical solution, and through the set correction mechanism, including photoelectric sensors and receivers, the position and status of the fabric pressing mechanism can be monitored in real time. This design ensures the accuracy and stability of the fabric pressing device during the sewing process, thereby significantly improving sewing precision.

[0009] Furthermore, both the transmitter and receiver heads are equipped with indicator lights at their front ends, and the transmitter and receiver ports are set at the same horizontal level and are positioned opposite each other.

[0010] By adopting the above technical solution, indicator lights are installed at the front end of the transmitter and receiver heads, which can intuitively display the working status of the correction mechanism, making it easier for operators to discover and adjust problems in a timely manner and improve work efficiency.

[0011] Furthermore, the first clamp and the second clamp are respectively clamped to the front end and the rear end of the machine tool. The bottom of the first clamp and the second clamp are screwed with a tightening block. The top of the tightening block is made of rubber and abuts against the machine tool.

[0012] By adopting the above technical solution, the first clamp and the second clamp are screwed to the front and rear ends of the machine tool through the tightening clamp block, which provides a firm clamping and is easy to adjust. At the same time, the rubber structure of the tightening clamp block can reduce damage to the machine tool.

[0013] Furthermore, a first connecting rod is mounted on the top of the first clamp via an adjusting bolt, and a first spreading wheel is rotatably connected to the front end of the first connecting rod; a second connecting rod is provided on the top of the second clamp.

[0014] By adopting the above technical solution, the first connecting rod is installed on the first clamp by adjusting bolts, and the front end is rotatably connected to the first spreading wheel, which makes it easy to adjust the position and angle of the spreading wheel to adapt to fabrics of different thicknesses and materials.

[0015] Furthermore, a third link is installed on one side of the second link via an adjusting bolt, and a second spreading wheel is provided at one end of the third link.

[0016] By adopting the above technical solution, the third link is installed on one side below the second link by adjusting bolts, and a second spreading wheel is provided at one end. It works in conjunction with the first spreading wheel to more stably compress the fabric.

[0017] Furthermore, a fourth link is mounted above one side of the second link via an adjusting bolt, and a tensioning wheel is rotatably connected to the top of the fourth link.

[0018] By adopting the above technical solution, a fourth connecting rod is installed above one side of the second connecting rod by adjusting bolts.

[0019] Furthermore, a pressure belt is fitted on the first spreading wheel, the second spreading wheel, and the tensioning wheel, and the outer surface of the pressure belt is configured with a rough granular structure.

[0020] By adopting the above technical solution, the pressing belt is sleeved on the first and second spreading wheels, and its outer surface has a rough granular structure, which can increase the friction with the fabric and improve the pressing effect.

[0021] Furthermore, the sewing machine includes a machine base, a base frame is provided at the bottom of the machine base, and a foot pedal is provided between the base frames.

[0022] By adopting the above technical solution, a basic structure for a sewing machine is provided, including a machine base, a frame, and a pedal, which provides a stable foundation for the installation and use of the pressing mechanism.

[0023] Furthermore, a lighting lamp is provided on one side of the top of the machine tool, and a main body is provided on the other side of the top of the machine tool, with a workbench provided on the lower inner side of the main body.

[0024] By adopting the above technical solution, lighting and the main body are installed on the top of the machine, and a workbench is installed on the lower inner side of the main body, providing operators with a better working environment and operational convenience.

[0025] In summary, the present invention has the following main advantages:

[0026] This invention incorporates a correction mechanism, a photoelectric sensor, a transmitter, a transmitter port, an indicator light, a tightening nut, a receiver, and a receiver head. The correction mechanism, through the cooperation of the photoelectric sensor and receiver, can monitor the relative positions of the first and second spreading wheels in real time. This automatic monitoring mechanism reduces the need for repeated manual adjustments, improving work efficiency. During use, when the sensor detects that the spreading wheels are incorrectly positioned or misaligned, it can promptly alert the operator through visual signals such as the indicator light, facilitating quick adjustments. After adjustment, by ensuring the two spreading wheels are in the correct horizontal position, the correction mechanism helps the pressure belt to press the fabric more evenly, preventing uneven pressing, wrinkles, or misalignment of the fabric during sewing. Therefore, through the above-mentioned design, and through efficient correction and adjustment, the problem of repeatedly manually adjusting the position of the spreading wheels in traditional fabric pressing devices is effectively solved, improving sewing efficiency and quality.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] A sewing machine with a fabric pressing device, such as Figures 1-4 As shown, the device includes a sewing machine 1 and a fabric pressing mechanism 2. The fabric pressing mechanism 2 includes a first clamp 201, a second clamp 202, a first connecting rod 204, and a third connecting rod 207. A mounting groove 209 is provided on one side of the first connecting rod 204 and the third connecting rod 207, and a straightening mechanism 3 is provided on one side of the mounting groove 209. The straightening mechanism 3 includes a photoelectric sensor 301 and a receiver 306. The photoelectric sensor 301 is located on one side of the third connecting rod 207, and the receiver 306 is located on one side of the first connecting rod 204. Each of the 306 components has a screw at its rear end, which passes through the mounting groove 209 and is fixedly connected by a tightening nut 305. The photoelectric sensor 301 has a transmitter head 302 at its front end, with a transmitter port 303 on one side. The receiver 306 has a receiver head 307 at its front end, with a receiver port on one side. This structure allows the fabric pressing device to be firmly installed on the sewing machine. At the same time, the setting of the correction mechanism can monitor and adjust the position of the fabric pressing device in real time, improving sewing efficiency and quality.

[0034] See Figure 1 , Figure 2Both the transmitter head 302 and the receiver head 307 are equipped with indicator lights 304 at their front ends. The transmitter port 303 and the receiver port are set at the same level and are positioned opposite each other. This design allows operators to quickly understand the working status of the correction mechanism, promptly identify and solve problems, and reduce debugging time and operational difficulty.

[0035] See Figure 1 , Figure 4 The first clamp 201 and the second clamp 202 are respectively clamped to the front end and the rear end of the machine base 101. The bottom of the first clamp 201 and the second clamp 202 are screwed with a tightening block 203. The top of the tightening block 203 is set with a rubber structure, and the tightening block 203 abuts against the machine base 101. This clamping and fixing method allows the pressing mechanism to be firmly installed on the machine base. At the same time, the rubber structure of the tightening block reduces the wear of the machine base and extends its service life.

[0036] See Figure 3 , Figure 4 The top of the first clamp 201 is equipped with a first connecting rod 204 via an adjusting bolt. The front end of the first connecting rod 204 is rotatably connected to a first spreading wheel 205. The top of the second clamp 202 is equipped with a second connecting rod 206. This connection method allows the first spreading wheel 205 to be adjusted in angle and position within a certain range to adapt to fabrics of different thicknesses and materials. This flexibility makes the fabric pressing device applicable to a wider range of sewing scenarios, improving its versatility and practicality. At the same time, the design of the adjusting bolt makes the adjustment process simple and quick, allowing operators to adjust according to actual needs.

[0037] See Figure 1 A third link 207 is installed on one side of the second link 206 via an adjusting bolt. A second spreading wheel 208 is provided at one end of the third link 207. In cooperation with the first spreading wheel 205, the second spreading wheel 208 can more stably press the fabric to prevent it from slipping or wrinkling during sewing. This double spreading wheel design improves the stability of the fabric and ensures the accuracy and quality of sewing. At the same time, the design of the adjusting bolt allows the position and angle of the second spreading wheel 208 to be adjusted to adapt to different sewing needs.

[0038] See Figure 4A fourth link 212 is installed on one side of the second link 206 via an adjusting bolt. The top of the fourth link 212 is rotatably connected to a tension wheel 210. The tension wheel 210 controls the tension of the pressure belt 211, ensuring that it always maintains the appropriate tension. A pressure belt that is too tight or too loose will affect the sewing effect. The design of the tension wheel effectively solves this problem. By adjusting the position and angle of the tension wheel with the adjusting bolt, the operator can easily adjust the tension of the pressure belt according to actual needs, improving the flexibility and accuracy of sewing.

[0039] See Figure 1 , Figure 4 A pressure belt 211 is fitted on the first spreading wheel 205, the second spreading wheel 208, and the tensioning wheel 210. The outer surface of the pressure belt 211 has a rough granular structure. The rough granular pressure belt can better fit the fabric surface and increase the friction between it and the fabric, thereby pressing the fabric more stably. This design prevents the fabric from slipping or wrinkling during sewing, improving the quality and efficiency of sewing. At the same time, the rough granular surface can also increase the wear resistance of the pressure belt and extend its service life.

[0040] See Figure 1 , Figure 2 The sewing machine 1 includes a machine base 101, a base frame 102 at the bottom of the machine base 101, and a foot pedal 103 between the base frames 102. The base frame 102 provides stable support for the sewing machine, ensuring that it will not shake or tilt during use. The foot pedal 103 provides the operator with a comfortable stepping experience, allowing them to easily control the operation of the sewing machine. This structural design improves the stability and comfort of the sewing machine, enabling the operator to perform sewing work for longer periods without feeling fatigued.

[0041] See Figure 1 , Figure 4 A light 104 is installed on one side of the top of the machine 101, and a main body 105 is installed on the other side of the top of the machine 101. A worktable 106 is installed on the lower inner side of the main body 105. The light 104 provides sufficient light for the operator to clearly see the sewing area and fabric details, thereby improving the accuracy and efficiency of sewing. The worktable 106 provides a spacious operating space for the operator to place fabric, tools and other items, making the sewing process smoother and more efficient. The design of these additional facilities improves the practicality and convenience of the sewing machine, making it easier for the operator to complete the sewing work.

[0042] The implementation principle of this embodiment is as follows: First, the pressing mechanism 2 is clamped to the front and rear ends of the sewing machine 1's base 101 by the first clamp 201 and the second clamp 202, and fixed by the tightening clamp 203 to ensure the stability of the pressing mechanism 2. Then, the first connecting rod 204, the second connecting rod 206, the third connecting rod 207 and the fourth connecting rod 212 are installed and adjusted by adjusting bolts so that the first spreading wheel 205, the second spreading wheel 208 and the tensioning wheel 210 are in appropriate positions.

[0043] Next, the pressing belt 211 is fitted onto the first spreading wheel 205 and the second spreading wheel 208, ensuring that the rough granular structure of its outer surface can effectively contact the fabric.

[0044] At this time, the photoelectric sensor 301 and receiver 306 in the correction mechanism 3 are fixed in the mounting groove 209 by screws and tightening nuts 305, ensuring that the transmitting port 303 of the transmitting head 302 and the receiving port of the receiver head 307 are at the same level and in opposite positions. During this process, the warning light will emit a green light, and when there is a deviation, it will emit a red light, to ensure that the pressure belt 211 can press the fabric evenly and stably, thereby improving the sewing effect and quality.
