Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester fabric processing technology, specifically to a shaping and pressing mechanism for polyester fabric processing. Background Technology
[0002] Polyester fabric is a type of fabric made from synthetic fibers. During the processing of polyester fabric, it needs to go through processes such as washing, opening, and dyeing. Then, the fabric is pulled out and laid out using a fabric spreading machine to align the edges of each layer of fabric, thereby shaping the fabric for subsequent cutting.
[0003] For example, Chinese patent document CN219791899U discloses a double-head fabric spreading machine, including a fabric spreading platform. A first frame slides on the fabric spreading platform, and two fabric spreading heads are mounted on the first frame. A guide plate is mounted on one side of each fabric spreading head, and a pressing mechanism is mounted on the guide plate to press two pieces of fabric together. A fabric cutting mechanism is mounted on the side of the first frame away from the fabric spreading heads. A second frame is mounted at one end of the fabric spreading platform, and a fabric clamping mechanism is mounted on the second frame, located on the side of the cutting mechanism away from the pressing mechanism. During fabric cutting, one end of the fabric is clamped by the clamping mechanism, and the area to be cut is pressed by the pressing mechanism, fixing both ends of the fabric. This prevents wrinkles from forming during cutting and improves the smoothness of the cut edge.
[0004] In the above technical solution, after clamping one end of the fabric with a fabric clamping mechanism, the fabric can be pulled and laid out as the first frame slides along the fabric laying platform. However, this fabric clamping mechanism mainly consists of multiple independent fabric clamps. In order to ensure that multiple fabric clamps can clamp the fabric synchronously, it is necessary to ensure that the installation angle of each fabric clamp is the same. This makes the debugging process cumbersome, and the use of multiple fabric clamps increases the overall cost. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shaping and pressing mechanism for polyester fabric processing, which can facilitate the pressing of the fabric and improve the convenience of debugging.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a shaping and pressing mechanism for processing polyester fabric, comprising a machine base, a sliding frame and a fixed frame on the machine base, the sliding frame being able to slide along the direction of the machine base to approach or move away from the fixed frame, the fixed frame being provided with a guide roller for feeding fabric, and a rotatable and liftable pressing frame connected to the fixed frame, the pressing frame being provided with transmission arms on both sides, and the sliding frame being provided with drive arms corresponding to the transmission arms on both sides, the sliding frame moving towards the fixed frame to feed the fabric to the pressing frame, and the pressing frame being lifted by contacting the transmission arms through the drive arms, and when the sliding frame moves away from the fixed frame, the drive arms disengage from the transmission arms, and the pressing frame presses down under the action of gravity to compress the fed fabric.
[0007] The present invention is further configured such that: connecting rods are provided on both sides of the pressing frame, one end of the connecting rod is rotatably connected to the inner wall of the fixed frame, and the other end is rotatably connected to the outer wall of the pressing frame.
[0008] The present invention is further configured such that a torsion spring is provided at the connection between the fabric pressing frame and the connecting rod.
[0009] The present invention is further configured such that: the drive arm is fixed inside the sliding frame and tilted toward the transmission arm; the height of the drive arm decreases sequentially along the direction toward the transmission arm to form an inclined coupling sidewall; one end of the transmission arm is provided with a rotatable coupling wheel, which can couple with the coupling sidewall.
[0010] The present invention is further configured such that: the inner wall of the pressing frame is provided with a connecting flange, one end of the connecting flange extends upward as an extension end, and the transmission arm is located at the end away from the coupling wheel and is rotatably connected to the extension end.
[0011] The present invention is further configured such that: the pressing frame is provided with a first connecting hole, and the connecting flange is provided with a second connecting hole opposite to the first connecting hole; the first connecting hole and the second connecting hole are connected by a bolt and nut, and the nut can abut against the transmission arm.
[0012] The present invention is further configured such that: the fixing frame has through arc-shaped guide holes on both sides, the arc-shaped guide holes are adapted to the rotation path of the connecting rod, the connecting rod is provided with a rotatable guide wheel, the guide wheel is coupled with the arc-shaped guide hole, and can form a guiding fit between the two.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] Because a sliding frame that can move closer to or further away from the fixed frame is provided, the sliding frame moves towards the fixed frame to feed the fabric to the pressing frame. The pressing frame is then lifted by the drive arm and transmission arm, allowing the fabric to be fed under the pressing frame. When the sliding frame moves away from the fixed frame, the drive arm and transmission arm disengage, and the pressing frame presses down under gravity to compress the fabric. Since the pressing frame is a single unit, it is easy to adjust. The gravity pressing method allows the pressing frame to quickly and stably compress the fabric when the sliding frame moves away from the fixed frame. Therefore, this effectively solves the technical problem that the existing fabric clamping mechanism mainly consists of multiple independent fabric clamps, which require adjustment of each fabric clamp during installation, resulting in a cumbersome overall adjustment process.

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 4As shown, this utility model discloses a shaping and pressing mechanism for processing polyester fabric, including a machine base 1. The machine base 1 is equipped with a sliding frame 2 and a fixed frame 3. The sliding frame 2 can slide along the direction of the machine base 1 to move closer to or further away from the fixed frame 3. The sliding frame 2 is moved by a gear and rack drive, which is a conventional structure. The fixed frame 3 is equipped with a guide roller 4 for feeding fabric, to guide the fabric fed in the previous sequence. A rotatable and liftable pressing frame 5 is connected to the fixed frame 3. The pressing frame 5 has transmission arms 6 on both sides, and the sliding frame 2 has drive arms 7 on both sides corresponding to the transmission arms 6. The sliding frame 2 moves towards the fixed frame 3 to feed the fabric towards the pressing frame 5, and the drive arms 7 contact the transmission arms 6 to lift the pressing frame 5, thus feeding the fabric below the pressing frame 5. When the sliding frame 2 moves away from the fixed frame 3, the drive arms 7 disengage from the transmission arms 6. The pressing frame 5 presses down under the action of gravity to compress the fed fabric. Since the pressing frame 5 is a whole, it is easy to adjust. By pressing down by gravity, the pressing frame 5 can quickly press down when the sliding frame 2 is away from the fixed frame 3. In this way, after one end of the fabric is pressed down, the fabric can be pulled to a predetermined length by the sliding frame 2 moving away from the fixed frame 3, so that the cutting mechanism above the drive arm 7 can cut it. After cutting, the sliding frame 2 is moved back to the fixed frame 3. Repeating the above steps can complete the layering of the fabric.
[0022] In this embodiment, connecting rods 8 are provided on both sides of the pressing frame 5. One end of the connecting rod 8 is rotatably connected to the inner wall of the fixed frame 3 via a pin, and the other end is rotatably connected to the outer wall of the pressing frame 5 via a pin. In this way, after the driving arm 7 contacts the transmission arm 6, it can push the pressing frame 5 to rotate around the connection center between the connecting rod 8 and the fixed frame 3, thereby realizing the lifting of the pressing frame 5. Furthermore, by providing a torsion spring 9 at the connection between the pressing frame 5 and the connecting rod 8, the resistance at the connection center between the connecting rod 8 and the fixed frame 3 during rotation is less than the resistance at the connection center between the connecting rod 8 and the pressing frame 5. Under the action of the pressing frame 5's own weight, the rotation angle between the pressing frame 5 and the connecting rod 8 can be less than the connection angle between the connecting rod 8 and the fixed frame 3 when the sliding frame 2 moves towards the fixed frame 3. This allows the pressing frame 5 to reset more quickly when the driving arm 7 and the transmission arm 6 disengage. Moreover, the component force generated by the time force of the torsion spring 9 can also act on the pressing frame 5. By cooperating with the pressing frame 5's own weight, the stability of pressing the fabric is improved.
[0023] In this embodiment, the cooperation structure between the drive arm 7 and the transmission arm 6 is as follows: one end of the drive arm 7 is fixed to the inner side of the sliding frame 2 by a threaded connection and is inclined toward the transmission arm 6; the other end of the drive arm 7 is lowered in height along the direction toward the transmission arm 6 to form an inclined coupling sidewall 71; one side end of the transmission arm 6 is provided with a rotatable coupling wheel 61, which can couple with the coupling sidewall 71. Thus, when the sliding frame 2 moves toward the fixed frame 3, and the coupling wheel 61 contacts the coupling sidewall 71, as the sliding frame 2 continues to move toward the fixed frame 3, the coupling wheel 61 can be lifted to drive the pressing frame 5 to rotate around the connection center between the connecting rod 8 and the fixed frame 3, thereby realizing the lifting of the pressing frame 5.
[0024] In this embodiment, a connecting flange 10 is provided on the inner wall of the pressing frame 5. One end of the connecting flange 10 extends upward as an extension end. The end of the transmission arm 6 located away from the coupling wheel 61 is rotatably connected to the extension end through a pin. When the sliding frame 2 slides away from the fixed frame 3, causing the driving arm 7 to disengage from the transmission arm 6, the friction generated by the contact between the coupling wheel 61 and the coupling side wall 71 can push the transmission arm 6 to rotate a certain angle in the clockwise direction, so that the coupling wheel 61 can disengage from the coupling side wall 71.
[0025] In addition, a first connecting hole is provided on the pressing frame 5, and a second connecting hole is provided on the connecting flange 10 opposite to the first connecting hole. The first connecting hole and the second connecting hole are fixedly connected by bolts and nuts 11. In addition, the nut 11 can abut against the transmission arm 6 to limit the transmission arm 6. That is, when the sliding frame 2 moves towards the fixed frame 3, the friction generated by the coupling wheel 61 contacting the coupling side wall 71 can push the transmission arm 6 to move counterclockwise, so that the transmission arm 6 can abut against the nut 11, thereby preventing the transmission arm 6 from moving erroneously when the coupling wheel 61 is lifted, and ensuring the stability when the pressing frame 5 is lifted.
[0026] In this embodiment, through arc-shaped guide holes 31 are further provided on both sides of the fixing frame 3. The arc-shaped guide holes 31 are adapted to the rotation path of the connecting rod 8. The connecting rod 8 is provided with a rotatable guide wheel 81. The guide wheel 81 is coupled with the arc-shaped guide hole 31. In this way, when the pressing frame 5 is lifted and drives the connecting rod 8 to rotate, the guide wheel 81 can move along the arc-shaped guide hole 31 to form a guiding fit between the two, thereby guiding the rotation of the connecting rod 8 and ensuring its smooth movement.
[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
