[0001] The invention belongs to the field of fabric trimming machines, and particularly relates to an automatic edge-aligning device for the tail trimming knife of a fabric shaping machine. Background Art

[0002] The fabric shaping machine is one of the key equipment often used in textile printing and dyeing production, mainly used for shaping fabrics. Fabrics need to be shaped after pretreatment, dyeing or printing. However, with the rapid development of the textile industry, people have higher and higher requirements for the quality of textile fabrics. Among them, ensuring the straightness of both sides of the textile fabric has become the most basic requirement;

[0003] In the prior art, in order to ensure the straightness of both sides of the fabric, edge trimming is often carried out on it. However, when the prior art trims the fabric, there is usually a lack of an edge-aligning and stabilizing device on both sides of the fabric, resulting in situations where the fabric cannot be cut, or is cut too much or too little during cutting, which affects the efficiency of edge trimming processing;

[0004] Therefore, this application proposes an automatic edge-aligning device for the tail trimming knife of a fabric shaping machine to improve the above defects. Summary of the Invention

The two groups of flow guiding mechanisms are both installed inside the blowing device and connected to the inner wall.

[0010] In a specific feasible implementation, the flow guiding mechanism includes a first bracket group, a first gear, a swing frame, a second bracket group, a third bracket group, a U-shaped frame, and a flow guiding plate. The swing frame is installed inside the first bracket group. First gears are symmetrically rotatably matched inside the swing frame. The first gears, the swing frame, and the first bracket group are all on the same center line and are rotatably matched. The second bracket group and the third bracket group are also installed on the swing frame. A U-shaped frame is fixed to the outside of the swing frame. A flow guiding plate is installed on the top of the U-shaped frame. The flow guiding plate, the U-shaped frame, and the swing frame are an integral structure.

[0011] In a specific feasible implementation, the second bracket group includes a support frame and a second gear. The support frame is rotatably matched on the second bracket group. The other end of the support frame is rotatably matched with the second gear through a rotating shaft and is eccentrically matched with the second gear.

[0012] In a specific feasible implementation, the third bracket group includes a side plate, a sliding shaft, a reciprocating frame, and a third gear. The side plate is fixed with a sliding shaft. The reciprocating frame is slidably matched on the sliding shaft. The reciprocating frame is rotatably matched with the third gear through a rotating shaft and is eccentrically matched with the third gear.

[0013] In a specific feasible implementation, the connecting shaft on the driven gear penetrates through the blowing device and is connected to the first gear, and drives the first gear to rotate on the first bracket group.

[0014] In a specific feasible implementation, the stabilizing device includes a bottom plate, sliding grooves, a driving gear, racks, a motor, and a stabilizing member.

[0016] According to the above-mentioned technical solution, an automatic edge-aligning device for the tail trimming knife of a fabric shaping machine of the present invention has the following beneficial effects:

[0017] (1) When the motor of the trimming machine drives the cutting knife to cut the fabric, the wind force reflux generated during the self-rotation of the motor is utilized by the blowing device. With the help of the meshing of the bevel gear and the driven gear, the first gear is driven to rotate on the first support group, driving the engaged second gear and third gear to rotate together, causing the second gear and the third gear to perform eccentric motion during rotation, driving the reciprocating frame to reciprocate on the sliding shaft, driving the deflector to swing reciprocally, dispersing and guiding the blown wind, so that the wind force will flow back to the fabric surface and evenly and smoothly flow to both sides of the fabric, being able to straighten the fabric, avoiding the situation that the fabric wrinkles during the cutting process, resulting in excessive cutting of the fabric, inability to cut or fabric loss.

[0018] (2) The present invention is provided with a stabilizing device on one side of the blowing device. By the forward and reverse rotation of the driving gear, the two groups of racks engaged with it on both sides slide relatively or towards each other in the chute. As the racks slide, the stabilizer at their bottom is driven to adjust according to the width of the fabric, thereby controlling the stabilizing range of the fabric.

[0019] (3) The present invention drives the column and the eccentric disc to perform eccentric rotational motion through the motor, driving the main frame and the rotating roller at its bottom to perform eccentric motion together. By means of the contact between the rotating roller and the fabric, it can flatten the fabric during eccentric rotation and cooperate with the blowing device, enabling the cutting knife to straighten the fabric when cutting the fabric and avoiding the fabric from wrinkling.

[0020] (4) The spring of the present invention can play a role in stretching and contracting the main frame, enabling the main frame to be applicable to fabrics of different thicknesses under the stretching and contracting action of the spring. Description of the Drawings

[0041] Embodiment 2: Please refer to Figures 6-8 , the specific embodiments of the present invention are as follows:

[0042] Please refer to Figure 6 , the stabilizing device 73 includes a bottom plate 731, sliding grooves 732, driving gears 733, racks 734, motors 735 and stabilizing members 736. One side of the bottom plate 731 is connected to the blowing device 72. Two groups of sliding grooves 732 are formed on the bottom plate 731. A driving gear 733 is installed at the center of the bottom plate 731. The driving gear 733 is driven by a motor located at the bottom of the bottom plate 731. Racks 734 are engaged with both the upper and lower sides of the driving gear 733. The two groups of racks 734 are slidably engaged with the sliding grooves 732. The sliding grooves 732 play a role in increasing the stability of the sliding of the racks 734. Motors 735 are installed on both groups of racks 734. The output end of the motor 735 is connected to the stabilizing member 736.

[0043] Please refer to Figures 7-8 , the stabilizing member 736 includes a column 21, an eccentric disc 22, a limiting disc 23, a spring 24, a main frame 25 and a rotating roller 26. The column 21 is connected to and driven by the motor 735. An eccentric disc 22 is fixed on the column 21. A limiting disc 23 is fitted outside the eccentric disc 22. The limiting disc 23 is connected to the rack 734. A number of springs 24 are arrayed at the bottom of the eccentric disc 22. The other ends of the number of springs 24 are connected to the main frame 25. A number of rotating rollers 26 are arrayed on the main frame 25. The number of rotating rollers 26 are rotatably engaged with the main frame 25 and have a diameter larger than the thickness of the main frame 25.

[0044] Please refer to Figure 6 , by the forward and reverse rotation of the driving gear 733, the two groups of racks 734 engaged with it on both sides will slide relatively or towards each other in the sliding grooves 732. As the racks 734 slide, the stabilizing member 736 at their bottom will be adjusted in width, thereby controlling the stable range of the fabric.

[0045] Please refer to Figures 7-8 , the motor 735 drives the column 21 and the eccentric disc 22 to perform eccentric rotational motion, so that the eccentric disc 22 can perform eccentric rotation on the limiting disc 23, and drive the main frame 25 and the rotating roller 26 at its bottom to perform eccentric motion together. By means of the contact between the rotating roller 26 and the fabric, the fabric can be flattened.

[0046] Please refer to Figures 7-8 , the spring 24 can play a role in expanding and contracting the main frame 25, so that the main frame 25 can be applicable to fabrics of different thicknesses under the expansion and contraction action of the spring 24.

[0047] Based on the above embodiments, the specific working principle is as follows:

[0048] When the trimming machine 1 trims the fabric, place the fabric on the trimming machine 1 and drive the cutter 2 on the trimming machine 1 to trim the fabric. The wind generated by the rotation of the motor of the cutter 2 will enter the inside of the centrifugal fan 5 through the air inlet pipe 4. Under the centrifugal action of the centrifugal fan 5, it is blown out through the air outlet pipe 71 and enters the blowing device 72. It is blown out through the air outlet at both ends of the blowing device 72 to blow air on both ends of the fabric on the trimming machine 1. The biaxial motor 721 drives the main shaft 722 and the bevel gear 723 to rotate. By meshing the bevel gear 723 with the driven gear 724, it will drive the first gear 12 to rotate on the first bracket group 11. When the first gear 12 rotates, it will drive the second gear 142 and the third gear 154 meshing with it to rotate together. With the eccentric cooperation of the support frame 141 and the second gear 142, and the eccentric cooperation of the reciprocating frame 153 and the third gear 154, the second gear 142 and the third gear 154 will perform eccentric motion when rotating, and drive the reciprocating frame 153 to reciprocate on the sliding shaft 152. As the reciprocating frame 153 reciprocates, it will drive the swing frame 13 and the deflector 17 on the swing frame 13 to swing reciprocally, dispersing and guiding the blown air, so that the air flow can flow smoothly and evenly to both sides of the fabric, enabling the cutting knife to straighten the fabric when cutting the fabric;

[0049] At the same time, by driving the forward and reverse rotation of the driving gear 733, it drives the two groups of racks 734 meshing with it on both sides to slide relatively or in opposite directions in the chute 732. As the racks 734 slide, it will drive the stabilizer 736 at its bottom to adjust according to the width of the fabric. Then, the motor 735 drives the column 21 and the eccentric disc 22 to perform eccentric rotational motion, driving the main frame 25 and the rotating roller 26 at its bottom to perform eccentric motion together. By means of the contact between the rotating roller 26 and the fabric, it can flatten the fabric during eccentric rotation and cooperate with the blowing device 72, enabling the cutting knife to straighten the fabric when cutting the fabric, and avoiding the situation that the fabric wrinkles during the cutting process, resulting in excessive cutting of the fabric, inability to cut, or fabric loss.

[0050] In the description of the present invention, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0051] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
