Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a feeding table for automatic sewing of sofa covers. Background Technology

[0002] Sofa covers are fabrics specifically designed to cover and protect sofas, and their production involves a series of sewing steps.

[0003] Currently, in the automated sewing process of sofa covers, operators need to accurately place the fabric at specific positions on the sewing table. Given the need to sew various different sofa cover fabrics, current technology uses multiple marking lines on the table, which often leads to operator errors in fabric placement. Therefore, designing a feeding table for automated sofa cover sewing is essential. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a feeding table for automatic sewing of sofa covers.

[0005] The purpose of this utility model can be achieved through the following technical solution: a feeding table for automatic sewing of sofa covers, comprising a table plate, characterized in that the table plate has a suction part for suctioning sofa cover fabric, a base plate is installed on the table plate, a movable beam is provided on the base plate through an adjustment structure, a plurality of connecting grooves of different shapes are opened on the movable beam, a connecting rod is detachably inserted into the connecting groove, and the connecting rod is connected to an L-shaped positioning member through a fixed column.

[0006] The control structure includes a guide rail, a slider, a cylinder, and a linkage plate. The guide rail is horizontally mounted on the base plate, the slider is slidably connected to the guide rail, the linkage plate is connected to the slider, the middle part of the movable beam is connected to the linkage plate, the cylinder is mounted on the base plate, and the piston rod of the cylinder is horizontally set, with the end of the piston rod of the cylinder connected to the linkage plate.

[0007] A pressure plate is also connected to the movable beam by locking screws, and the pressure plate has a rubber pad.

[0008] The cylinder is mounted on the base plate via an L-shaped mounting bracket.

[0009] The locking screw is a hand-tightening component.

[0010] Compared with existing technologies, this automatic sofa cover sewing feeder has the following advantages:

[0011] In this invention, several connecting grooves of different shapes are provided on the movable beam, so that the required L-shaped positioning parts can be connected to the corresponding connecting grooves. This prevents the sofa cover fabric from being placed in the wrong position and greatly reduces the error rate. Attached Figure Description

[0015] In the diagram, 1 is the platform; 1a is the suction part; 2 is the cylinder; 3 is the base plate; 4 is the movable beam; 4a is the connecting groove; 5 is the pressure plate; 6 is the L-shaped positioning part; 7 is the connecting rod; 8 is the locking screw; 9 is the rubber pad; 10 is the linkage plate; 11 is the slider; 12 is the fixed column; 13 is the guide rail; and 14 is the L-shaped mounting part. Detailed Implementation

[0016] 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.

[0017] like Figures 1-3 As shown, the automatic sofa cover sewing feeding table includes a table plate 1. The table plate 1 has a suction part 1a for holding the sofa cover fabric. In this embodiment, the suction part 1a uses existing technology to achieve its suction effect on the sofa cover fabric, while not affecting the operator's ability to place the sofa cover fabric in the required position. A base plate 3 is installed on the table plate 1. A movable beam 4 is set on the base plate 3 through an adjustment structure. Several connecting grooves 4a of different shapes are opened on the movable beam 4. Connecting rods 7 are detachably inserted into the connecting grooves 4a. The connecting rods 7 are connected to the L-shaped positioning member 6 through the fixing column 12. With this structure, the L-shaped positioning member 6 can play a positioning role when the sofa cover fabric is placed. This is an existing technology.

[0018] The control structure includes a guide rail 13, a slider 11, a cylinder 2, and a linkage plate 10. The guide rail 13 is horizontally mounted on the base plate 3, the slider 11 is slidably connected to the guide rail 13, the linkage plate 10 is connected to the slider 11, the middle part of the movable beam 4 is connected to the linkage plate 10, and the cylinder 2 is mounted on the base plate 3. Specifically, the cylinder 2 is mounted on the base plate 3 through an L-shaped mounting piece 14; and the piston rod of the cylinder 2 is horizontally set, with the end of the piston rod connected to the linkage plate 10. With this structure, after the sofa cover fabric is placed in place, the piston rod of the cylinder 2 retracts, which can retract the L-shaped positioning piece 6, thereby avoiding interference between the existing material picking tray and the L-shaped positioning piece 6 in the automatic sofa cover sewing equipment. At the same time, the material picking tray also uses existing technology to pick up the sofa cover fabric at the suction holding part 1a.

[0019] The movable beam 4 is also connected to a pressure plate 5 by a locking screw 8. Specifically, the locking screw 8 is a hand-tightening component; the pressure plate 5 has a rubber pad 9, and the connecting rod 7 can be reliably connected to the movable beam 4 through the pressure plate 5.

[0020] In this invention, by providing several connecting grooves 4a of different shapes on the movable beam 4, the required L-shaped positioning piece 6 can be connected to the corresponding connecting groove 4a, thus preventing misplacement of the sofa cover fabric and greatly reducing the error rate of placement.

[0021] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
