A specific frame needs to be set up to install the sliding device, which is not very versatile and has high manufacturing costs. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a simple feeding device for buttonhole machines that is simple in structure and easy to use.

[0005] The objective of this utility model can be achieved through the following technical solution: A simple feeding device for a buttonhole machine, located on the right side of the buttonhole machine head, includes a horizontally arranged fabric feeding table and a driving component for driving the fabric feeding table to move back and forth. The front and rear sides of the top of the fabric feeding table are each provided with a pressure plate and a driving component, and the two driving components are used to drive the two pressure plates to rise and fall respectively. A clamping opening for clamping the fabric is formed between the pressure plate and the fabric feeding table. The device is characterized in that a front baffle and a rear baffle are respectively fixed to the front and rear sides of the top of the fabric feeding table, and the two clamping openings are located between the front baffle and the rear baffle. The front baffle is used to limit the leftward movement of the fabric, and the rear baffle is used to limit the backward movement of the fabric.

[0006] When in use, the operator is positioned to the right of the buttonhole machine head. The fabric is placed on the feed table and pushed to the left towards the buttonhole machine head sewing position. The movement position is limited by contact with the front and rear fabric blocks. Finally, the two pressure plates descend to hold the fabric in place for subsequent sewing operations.

[0007] The front and rear fabric blocks work together to define the area where the fabric is placed, allowing the fabric to be pushed into place in one go. This greatly reduces the number of fabric adjustment steps and makes sewing easier. It has the advantages of simple structure and easy use.

[0008] In the aforementioned simple feeding device for buttonhole machines, the back panel fabric block is connected to the feeding table via a rear connection structure, so that the back panel fabric block can be locked at multiple positions in the front-to-back direction.

[0009] In the aforementioned simple feeding device for buttonhole machines, the aforementioned front fabric block is connected to the feeding table via a front connecting structure, so that the front fabric block can be locked at multiple positions in the front-back direction.

[0010] Both the front and rear fabric panels can be adjusted forward and backward to change the distance between them, thus adapting to different types of fabrics and offering good practicality.

[0011] In the aforementioned simple feeding device for buttonhole machines, the front connecting structure includes a front through hole that runs vertically through the front baffle block. A row of front threaded holes distributed front to back is provided on the feeding table.

[0014] In the aforementioned simple feeding device for a buttonhole machine, the front baffle is long and extends forward and backward. The vertical cross-section of the front baffle is L-shaped. The front baffle consists of a vertically arranged baffle section and a horizontally arranged positioning section. The positioning section is located to the left of the baffle section, and the aforementioned front through hole is located on the positioning section to better limit the fabric.

[0015] In the aforementioned simple feeding device for a buttonhole machine, the back panel cloth is L-shaped and horizontally positioned, with the corner of the back panel cloth facing the aforementioned clamping opening.

[0016] In the aforementioned simple feeding device for the buttonhole machine, both ends of the back cover block are provided with the aforementioned rear through holes, and there are two rows of rear threaded holes corresponding to the two rear through holes respectively, making the positioning of the back cover block more stable.

[0017] In the aforementioned simple feeding device for a buttonhole machine, the rear through-hole at the left end of the back panel is a waist-shaped hole, and its length extends both front and back. This design facilitates easier adjustment of the back panel.

[0018] In the aforementioned simple feeding device for buttonhole machines, the driving component is a linear module, which includes a slide table, and the fabric feeding table is fixed on the slide table. This design not only reduces cost but also facilitates assembly.

[0019] In the aforementioned simple feeding device for buttonhole machines, a sensing component is installed between the feeding table and the linear module. This component includes a sensing element and two sensors that control the operation of the linear module by detecting the position of the sensing element. Two sensing elements and two sensors are installed at the front and rear ends of the feeding table, respectively, and two sensors are installed at the front and rear ends of the linear module, respectively, with the sensing element positioned between the two sensors. In use, the sensing element and sensors work together to determine the two origin positions of the feeding table. Depending on the type of clothing, the linear module stops or drives the feeding table forward or backward a set distance after it reaches the origin position.

[0020] In the aforementioned simple feeding device for a buttonhole machine, the buttonhole machine head is mounted on a horizontally positioned platform. A base plate is horizontally pressed against the top of the platform, and the linear module is fixed to the base plate. U-shaped clamps are fitted around the four edges of the base plate. One end of each clamp has a vertically threaded hole, into which a bolt is screwed. A pressure block is fixed to the end of the bolt.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figure 1 As shown, the simple feeding device for this buttonhole machine is located on the right side of the machine head 1. The feeding device includes a horizontally arranged feeding table 2 and a driving component for driving the feeding table 2 to move back and forth.

[0031] in,

[0032] The buttonhole machine head 1 is mounted on the table 4, and the drive component is fixed to the table 4 via the base plate 11. Preferably, the drive component is a linear module 3, which includes a slide table, and the fabric feeding table 2 is fixed on the slide table. This not only reduces cost but also facilitates assembly. In the actual product, a sensing component is provided between the fabric feeding table 2 and the linear module 3. The sensing component includes a sensing element 13 and two sensors 12 that control the operation of the linear module 3 by detecting the position of the sensing element 13. There are two sensing elements 13 and two sensors 12. The two sensing elements 13 are respectively installed at the front and rear ends of the fabric feeding table 2, and the two sensors 12 are respectively installed at the front and rear ends of the linear module 3, with the two sensing elements 13 positioned between the two sensors 12. In use, the sensors 12 are electrically connected to the control unit of the linear module 3 to detect the position of the sensing element 13, determine the two origin positions of the fabric feeding table 2, and, depending on the type of clothing, the linear module 3 stops or drives the fabric feeding table 2 forward or backward a set distance after the fabric feeding table 2 moves to the origin position. The sensor 13 can be a proximity switch, a position sensor, a grating, etc., and its structure and working principle are existing and will not be explained in detail here.

[0033] The fabric feeding table 2 is long and extends forward and backward. Pressure plates 5 and driving components 6 are provided on the front and rear sides of the top of the feeding table 2, and the two driving components 6 are used to drive the two pressure plates 5 to rise and fall respectively. A clamping opening for clamping the fabric is formed between the pressure plates 5 and the feeding table 2, and the two clamping openings are positioned opposite each other. In this embodiment, the driving component 6 is a telescopic cylinder, the cylinder body of which is fixed to the base plate, and the piston rod of which is fixedly connected to the pressure plates 5. Of course, the driving component 6 can also be a hydraulic cylinder or an electric push rod.

[0034] like Figure 1 As shown, a front baffle block 7 and a rear baffle block 8 are fixed to the front and rear sides of the top of the fabric feeding table 2, respectively, and the two clamping openings are located between the front baffle block 7 and the rear baffle block 8. The front baffle block 7 is used to limit the leftward movement of the fabric, and the rear baffle block 8 is used to limit the rearward movement of the fabric.

[0035] When in use, the operator is positioned to the right of the buttonhole machine head 1. The fabric is placed on the feed table 2 and pushed to the left towards the sewing position of the buttonhole machine head 1. The fabric's movement is limited by contact with the front and rear fabric blocks 7 and 8. Finally, the two pressure plates 5 descend to hold the fabric in place for subsequent sewing operations.

[0036] The front and rear fabric blocks 7 and 8 work together to define the fabric placement area, allowing the fabric to be pushed into place in one go, greatly reducing the number of fabric adjustment steps and making fabric sewing more convenient. It has the advantages of simple structure and easy use.

[0037] In this embodiment,

[0038] The connection method between the base plate 11 and the table plate 4 is as follows: The base plate 11 is horizontally positioned and presses against the table plate 4. The four edges of the base plate 11 are fitted with U-shaped clamps 14. One end of the clamp 14 has a vertical threaded hole, and a bolt is screwed into the threaded hole. A pressure block is fixed to the end of the bolt. The bottom wall of the table plate 4 and the top wall of the base plate 11 are respectively pressed against the other end of the clamp 14 and the pressure block. By unscrewing the bolt and pulling out the clamp, the base plate 11 and the table plate 4 can be loosened, making it convenient to disassemble and assemble the entire feeding device. At the same time, the above design allows the feeding device to be adapted to different buttonhole machines, with good adaptability and low cost.

[0039] The rear fabric block 8 is connected to the fabric feeding table 2 via a rear connecting structure, allowing it to be locked at multiple positions in the front-to-back direction. The front fabric block 7 is connected to the fabric feeding table 2 via a front connecting structure, allowing it to be locked at multiple positions in the front-to-back direction.

In this way, the position of the front baffle 7 can be changed by screwing the rear bolt 10 into different rear threaded holes 2b. It has the advantages of simple structure and convenient operation.

[0043] In actual products, such as Figure 1 and Figure 2 As shown, the front baffle 7 is long and extends from front to back. The vertical cross-section of the front baffle 7 is L-shaped. The front baffle 7 consists of a vertically arranged baffle section 7b and a horizontally arranged positioning section 7c. The positioning section 7c is located to the left of the baffle section 7b, and the front through hole 7a is set on the positioning section 7c to better limit the fabric.

[0044] like Figure 1 and Figure 3 As shown, the backstop 8 is L-shaped and horizontally positioned, with its two ends distributed to the left and right, and the corners of the backstop 8 facing the clamping opening. Further, each end of the backstop 8 has a rear through hole 8a, and two rows of rear threaded holes 2b corresponding to the two rear through holes 8a respectively, making the positioning of the backstop 8 more stable. Furthermore, the rear through hole 8a at the left end of the backstop 8 is an oblong hole, and its length extends front to back. This design facilitates easier adjustment of the backstop 8.

[0045] In the actual product, the front pressure plate 5 extends horizontally, with its left end connected to the corresponding drive unit 6, and its right end tilted upwards to allow the fabric to be smoothly fed into the front clamping opening. The rear pressure plate 5 extends longitudinally, with its rear end connected to the corresponding drive unit 6.
