Description

Technical Field

[0001] This application relates to the technical field of sewing equipment accessories, and in particular to a feeding device for sewing equipment. Background Technology

[0002] When sewing buttons onto clothing, fabrics, hats, etc., a button sewing machine is generally required. The structure of a button sewing machine is disclosed in Chinese Patent Application No. 2025103988088. A male button feeding mechanism transports male buttons to a button sewing assembly mechanism, and a female button feeding mechanism transports female buttons to the upper end face of a female button receiving column. Then, the worker places the fabric to be sewn onto the female button horizontally above the female button. At this time, the perforation driving cylinder drives the perforation column to move down and abut against the positioning ring. Under the action of the perforation cutting edge of the fabric and the perforation column, the fabric is perforated. Then, the male button stamping column moves down to fasten the male button and the female button together.

[0003] Regarding the aforementioned technologies, the inventors believe that the fabric requires workers to manually feed it into the button-attaching machine for button-attaching, which results in high labor intensity and low work efficiency for the workers. Therefore, there are certain areas for improvement. Utility Model Content

[0018] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0019] A feeding device for sewing equipment, as described above Figure 1 and Figure 2 As shown, the device includes a frame 1 and a feeding table 2 mounted on the frame 1. The frame 1 is equipped with a drive mechanism 3 for driving the feeding table 2 to slide along the frame 1. Figure 1 For reference, the sliding direction of the feeding table 2 is left and right. The operator is located at the front side of the feeding table 2, and the sewing equipment is set on the rear side of the feeding table 2. The sewing equipment can be an automatic button-making machine, a buttonhole machine, or a button-attaching machine. This embodiment will be described using a button-attaching machine as an example.

[0020] Reference Figure 2 and Figure 3 As shown, two clamping parts 4 are provided on the side of the feeding table 2. The two clamping parts 4 are located on the rear side of the feeding table 2 near the sewing equipment. The two clamping parts 4 are spaced apart and opposite to each other, forming a working area between them. The sewing equipment is located in the working area. A moving part 5 is provided on the feeding table 2, which is connected to one of the clamping parts 4. The moving part 5 is used to drive one of the clamping parts 4 to move away from the other clamping part 4.

[0021] By placing the garment or fabric on the feeding table 2, with the side of the garment or fabric to be processed located in the sewing equipment, the two clamping parts 4 of the feeding table 2 clamp the garment or fabric, and the moving part 5 drives one of the clamping parts 4 to move, thereby tightening the garment or fabric. Subsequently, the drive mechanism 3 drives the feeding table 2 to slide, so that the button attaching machine or other sewing equipment can process the garment or fabric in the working area.

[0022] The structure of the drive mechanism 3, the clamping part 4, and the moving part 5 will be described in detail below.

[0023] The drive mechanism 3 includes two sliding rails 31 arranged side by side on the frame 1. A sliding block is slidably connected to the sliding rail 31 at the bottom of the feeding platform 2. Two sliding blocks are provided at the bottom of the feeding platform 2, each matching one of the sliding rails 31. Synchronous pulleys are rotatably mounted at both ends of the sliding rails 31. A synchronous belt is mounted on each synchronous pulley, with the ends of the belt connected in a ring on the pulley. The synchronous belt is connected to the sliding block. A drive unit is provided on the sliding rails 31 to drive the synchronous pulleys to rotate. The rotation of the synchronous pulleys drives the synchronous belt to slide the feeding platform 2 along the sliding rails 31.

[0024] The drive unit includes a servo motor 32 and a linkage shaft 33. The two ends of the linkage shaft 33 are respectively connected to the synchronous pulleys of two sliding rails 31. The servo motor 32 is fixed on one of the sliding rails 31, and the output shaft of the servo motor 32 is coaxially fixed on the synchronous pulley of the sliding rail 31.

[0025] One clamping part 4 is mounted on the moving part 5, and the other clamping part 4 is mounted on the feeding table 2. Each clamping part 4 includes a clamping cylinder 41. Thus, the clamping cylinder 41 of one clamping part 4 is fixed to the moving part 5, and the clamping cylinder 41 of the other clamping part 4 is fixed to the feeding table 2. A lower clamping plate 42 is fixedly mounted on the cylinder body of the clamping cylinder 41. The output rod of the clamping cylinder 41 moves vertically, and an upper clamping plate 43 is mounted on the output rod. The upper clamping plate 43 and the lower clamping plate 42 are arranged opposite to each other, thereby achieving the clamping action on the fabric or clothing. An upper clamping pad 44 is mounted on the upper clamping plate 43, and a lower clamping pad 45 is mounted on the lower clamping plate 42. The upper clamping pad 44 and the lower clamping pad 45 are made of rubber or plastic to reduce damage to the fabric or clothing during clamping.

[0026] The moving part 5 includes a moving cylinder 51 fixedly mounted on the feeding table 2. A mounting plate 52 is connected to the output rod of the moving cylinder 51, and a clamping part 4 is mounted on the mounting plate 52 to... Figure 1 As a reference direction, the output rod of the moving cylinder 51 extends to the right, so that when the clamping part 4 clamps the clothes or fabric, the moving part 5 can drive the clamping part 4 to move, thereby pulling the clothes or fabric and flattening the sides of the clothes or fabric to facilitate the operation of the sewing equipment.

[0027] Each clamping cylinder 41 is equipped with a gripper cylinder 6, and the gripper cylinder 6 is equipped with a gripper 7. The gripper 7 of the two clamping cylinders 41 are arranged opposite each other. The gripper 7 can further clamp the two sides of the clothes or fabric, thereby further flattening the clothes or fabric.

[0028] It is worth noting that the frame 1 is equipped with at least one supporting cylinder 8 in the working area. The output rod of the supporting cylinder 8 is equipped with a supporting plate 9. There are two supporting cylinders 8. The extension and retraction direction of the output rod of the supporting cylinder 8 is in the vertical direction. When the clothes or fabric are placed on the feeding table 2, the supporting plate 9 can support the clothes or fabric in the working area, so as to facilitate the subsequent flattening processing of the clothes or fabric.

[0029] After the clamping part 4 clamps the clothes or fabric, the supporting piece 9 will descend under the action of the supporting cylinder 8, thereby avoiding interference with the subsequent sliding of the feeding table 2.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
