Description

Technical Field

[0001] This utility model relates to the technical field of knitted garment processing equipment, and in particular to a sewing device for knitted garments. Background Technology

[0002] Knitted garments refer to all kinds of clothing made of knitted fabrics. These fabrics are woven using knitting techniques and have unique properties and characteristics.

[0003] In the production of knitted garments, due to the elasticity and softness of the fabric, the edges of the knitted fabric are prone to curling. Therefore, during the processing of knitted garments, it is necessary to remove the curled edges. Currently used logarithmic sewing devices can usually only sewing one side of the fabric. However, the curled edge of the fabric may be on both sides. Devices that can only sewing one side require manual adjustment of the other side of the curled edge, or the sewing device may need to be used again to sewing the other side of the fabric, resulting in low sewing efficiency.

[0004] Therefore, we provide a sewing device for knitted garments. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a sewing device for knitted garments, thereby improving the efficiency of fabric sewing.

[0006] In view of this, the present invention provides a sewing device for knitted garments, comprising two symmetrically distributed housings, a fixed sewing assembly disposed between the two housings, a movable sewing assembly disposed above the fixed sewing assembly, a connecting support plate disposed above the movable sewing assembly, movable columns mounted on opposite ends of the connecting support plate, a rotating column disposed outside the movable column, a synchronous wheel mounted on the upper end of the rotating column, a synchronous belt disposed outside the synchronous wheel, a motor disposed outside the synchronous belt, and a spiral groove penetrating through the outer surface of the rotating column.

[0007] Preferably, there are two fixed paddle assemblies, which are symmetrically distributed between the two housings. Each fixed paddle assembly consists of a drive motor, a pulley, and a belt.

[0008] Preferably, the fixed paddle assembly and the movable paddle assembly are the same size and specifications, the fixed paddle assembly and the movable paddle assembly are symmetrically distributed on the same vertical plane, and the belts on the fixed paddle assembly and the movable paddle assembly on the same vertical plane rotate in opposite directions.

[0009] Preferably, the two symmetrically distributed movable paddle assemblies are simultaneously fixedly connected to the lower surface of the connecting support plate, and the connecting support plate is always in a horizontal state.

[0010] Preferably, the lower end of the rotating column is rotatably connected to the housing, the moving column slides inside the spiral groove, the two spiral grooves are symmetrically staggered, the outer end of the moving column is inserted into the interior of the rotating column, and the two ends of the spiral groove are located at opposite ends of the rotating column.

[0013] Compared with the prior art, this utility model provides a sewing device for knitted garments, which has the following advantages: This invention, with the cooperation of a fixed prying component and a movable prying component, can simultaneously pry both sides of the fabric, further improving the prying efficiency of the fabric compared to devices that can only pry one side of the fabric.

[0014] This invention uses a motor to drive a synchronous wheel, which in turn rotates a rotating column, changing the position of the moving column inside the spiral groove.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0020] Example: A sewing device for knitted garments, such as Figures 1-4 As shown, it includes two symmetrically distributed housings 1, a fixed paddle assembly 2 is arranged between the two housings 1, a movable paddle assembly 3 is arranged above the fixed paddle assembly 2, a connecting support plate 4 is arranged above the movable paddle assembly 3, movable columns 5 are installed at opposite ends of the connecting support plate 4, a rotating column 6 is arranged outside the movable column 5, a synchronous wheel 8 is installed at the upper end of the rotating column 6, a synchronous belt 9 is arranged outside the synchronous wheel 8, a motor 10 is arranged outside the synchronous belt 9, and a spiral groove 7 is formed through the outer surface of the rotating column 6.

[0021] There are two fixed paddle assemblies 2, which are symmetrically distributed between the two housings 1. The fixed paddle assemblies 2 consist of a drive motor, a pulley, and a belt.

[0022] The fixed paddle assembly 2 and the movable paddle assembly 3 are the same size and specifications. The fixed paddle assembly 2 and the movable paddle assembly 3 are symmetrically distributed on the same vertical plane, and the belts on the fixed paddle assembly 2 and the movable paddle assembly 3 on the same vertical plane rotate in opposite directions.

[0023] Two symmetrically distributed movable paddle assemblies 3 are simultaneously fixedly connected to the lower surface of the connecting support plate 4, and the connecting support plate 4 is always in a horizontal state.

[0024] The lower end of the rotating column 6 is rotatably connected to the housing 1. The moving column 5 slides inside the spiral groove 7. The two spiral grooves 7 are symmetrically staggered. The outer end of the moving column 5 is inserted into the rotating column 6. The two ends of the spiral groove 7 are located at opposite ends of the rotating column 6.

[0025] Two synchronous pulleys 8 are simultaneously engaged with synchronous belt 9. The output end of motor 10 is fixedly connected to the upper surface of one of the synchronous pulleys 8. An L-shaped support block is installed on the outer surface of motor 10. Motor 10 is fixedly connected to one of the housings 1 through the L-shaped support block.

[0026] Traditional fabric shearing devices use a drive motor to rotate a pulley and belt during fabric laying. When the belt contacts the fabric's rolled edge, friction pulls the edge flat, thus shearing the fabric. This device adjusts the distance between the movable shearing assembly 3 and the belt on the fixed shearing assembly 2 according to the fabric thickness. First, the motor 10 is started, driving one of the synchronous pulleys 8 to rotate. Connected by the synchronous belt 9, both synchronous pulleys 8 rotate synchronously in the same direction. During rotation, the two synchronous pulleys 8 drive two rotating columns 6 to rotate synchronously in the same direction. Because the two spiral grooves 7 are symmetrically staggered, the moving columns 5 at both ends of the connecting support plate 4 slide inside the spiral grooves 7. Since the spiral grooves 7 are designed as a top-to-bottom spiral, as the rotating columns 6 drive the spiral grooves 7 to rotate, the moving columns 5 move vertically along the spiral grooves 7. During the movement of the connecting support plate 4, the connecting support plate 4 simultaneously drives... The movable prying assembly 3 moves until the fabric can pass between the belts on the fixed prying assembly 2 and the movable prying assembly 3, completing the adjustment. After the movable prying assembly 3 is adjusted, the fabric is inserted through the gap between the fixed prying assembly 2 and the movable prying assembly 3. During the flattening process of the fabric, the belts on the fixed prying assembly 2 and the movable prying assembly 3 will pry the rolled edges of the upper and lower surfaces of the fabric. With the cooperation of the fixed prying assembly 2 and the movable prying assembly 3, both sides of the fabric can be pryed simultaneously. Compared with the device that can only pry one side of the fabric, the prying efficiency of the fabric is further improved. The synchronous wheel 8 driven by the motor 10 drives the rotating column 6 to rotate, changing the position of the moving column 5 inside the spiral groove 7, thereby driving the movable prying assembly 3 to move in the height direction. The distance between the fixed prying assembly 2 and the movable prying assembly 3 can be adjusted according to the different thicknesses of the fabric, so that the fixed prying assembly 2 and the movable prying assembly 3 can pry the rolled edges of fabrics of different thicknesses, further improving the applicability of the prying assembly.

[0027] like Figures 1-4As shown, two limiting holes 11 are symmetrically opened through the upper surface of the connecting support plate 4. Limiting posts 12 are inserted into the limiting holes 11, and the lower end of the limiting posts 12 is fixedly connected to the housing 1.

[0028] When the connecting support plate 4 drives the movable paddle assembly 3 to adjust its height, the connecting support plate 4 will drive the movable paddle assembly 3 to adjust its height along the outer surface of the limiting post 12. With the cooperation of the limiting post 12 and the limiting hole 11, the moving direction of the connecting support plate 4 is guided and limited, ensuring the accuracy of the moving direction of the connecting support plate 4. At the same time, it ensures the stability of the verticality of the connecting support plate 4 during the movement, ensuring that the connecting support plate 4 is always in a horizontal state during the movement.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
