Abstract

The utility model discloses a quick tensioning device for polyester fabric production, which comprises a frame, two front squeeze rollers and two rear squeeze rollers are mounted on the frame, a rotating shaft is rotatably connected onto the frame, and a hollow sleeve is mounted on the rotating shaft. Through the cooperative arrangement of the hollow shaft sleeve and the sliding rod, when the polyester cloth needs to be tensioned, the linear actuator pushes the sliding rod, so that the sliding rod drives the hollow shaft sleeve to rotate, and the sliding rod slides out in the direction of the polyester cloth in the hollow shaft sleeve while the sliding rod increases pressure on the polyester cloth from an inclined state to a vertical state; the tension force on the polyester cloth is further increased; when the sliding rod gradually rotates to be in the vertical state, the friction wheel in transmission connection with the tensioning wheel abuts against the friction block, the closer the sliding rod is to be in the vertical state, the larger the friction force of the friction block on the friction wheel is, and therefore the friction wheel limits the tensioning wheel driven by the polyester cloth to rotate to rotate, and the tensioning effect of the tensioning wheel on the polyester cloth is further improved.

Description

Technical Field

[0001] The utility model relates to the technical field of quick tensioning of all-polyester cloth, in particular to a quick tensioning device for producing all-polyester cloth. Background Art

[0002] Polyester cloth is made of polyester fiber. It is durable, wrinkle-resistant, iron-free, and non-sticky. It is mainly used for clothing and interior decoration. Its biggest advantage is its good wrinkle resistance and shape retention, and it has high strength and elastic recovery ability.

[0003] During the production of polyester fabric, due to its high elasticity, it is easy to become loose during the transportation process, so that the fabric cannot be conveyed in a tensioned state, which may further cause wrinkles, and it is impossible to quickly tension it in real time, which reduces the production quality of the polyester fabric. Therefore, a quick tensioning device is needed in the production of polyester fabric.

[0004] However, the tensioning range and capacity of the quick tensioning device in the prior art are relatively weak. Therefore, it is necessary to design a quick tensioning device for all-polyester fabric production. Utility Model Content

[0005] Based on this, it is necessary to provide a quick tensioning device for producing all-polyester fabrics in response to the above technical problems.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a quick tensioning device for full polyester cloth production, comprising a frame, wherein two front squeezing rollers and two rear squeezing rollers are installed on the frame, the frame is rotatably connected with a rotating shaft, a hollow sleeve is installed on the rotating shaft, a sliding rod is slidably connected in the hollow sleeve, the bottom end of the sliding rod is always in contact with the frame, a hinge seat is installed at the bottom end of the sliding rod, a linear actuator is installed on the frame, the output end of the linear actuator is hinged with the hinge seat, and a tensioning wheel is rotatably installed on the top end of the sliding rod; a conveyor belt shaft is installed on the tensioning wheel, the conveyor belt shaft and the tensioning wheel are coaxially arranged, a conveyor belt shaft 2 is rotatably connected to the sliding rod, the conveyor belt shaft 2 is connected to the conveyor belt shaft through a belt transmission assembly, a friction wheel is installed on the conveyor belt shaft 2, a spring is installed on the frame, a friction block is installed at the output end of the spring, and the friction block and the friction wheel are arranged in coordination.

[0007] Preferably, a roller is installed at the bottom end of the slide rod, and the roller is always in contact with the frame.

[0008] Preferably, an arc-shaped groove is provided on the friction block.

[0009] Preferably, a telescopic rod is installed on the frame, the output end of the telescopic rod is connected to the friction block, and the spring is located inside the telescopic rod.

[0010] Preferably, an articulated block is installed at the output end of the linear actuator, and the articulated block is hinged to the articulated seat.

[0011] Preferably, a wear-resistant layer is installed in the arc-shaped groove.

[0012] Compared with the prior art, this technical solution has at least one of the following beneficial effects:

[0013] Through the coordination of the hollow shaft sleeve and the slide bar, when the polyester fabric needs to be tensioned, the linear actuator pushes the slide bar, so that the slide bar drives the hollow shaft sleeve to rotate, changing from an inclined state to a vertical state. While the slide bar increases the pressure on the polyester fabric, the slide bar slides out in the hollow shaft sleeve toward the polyester fabric, further increasing the tension on the polyester fabric.

[0014] When the slide rod gradually rotates to become a vertical state, the friction wheel and the friction block connected to the tensioning wheel abut against each other. The closer the slide rod is to the vertical state, the greater the friction force of the friction block on the friction wheel. As a result, the tensioning wheel driven by the polyester cloth to rotate due to the friction wheel limit rotates, so that the tensioning effect of the tensioning wheel on the polyester cloth is further improved.

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] See also Figures 1 to 4 The embodiment of the present application provides a fast tensioning device for full polyester fabric production, including a frame 1, two front squeezing rollers 2 and two rear squeezing rollers 3 are installed on the frame 1, a rotating shaft 4 is rotatably connected to the frame 1, a hollow sleeve 5 is installed on the rotating shaft 4, a sliding rod 6 is slidably connected in the hollow sleeve 5, the bottom end of the sliding rod 6 is always in contact with the frame 1, and a hinge seat 7 is installed at the bottom end of the sliding rod 6. A linear actuator 8 is installed on the frame 1, and the linear actuator 8 can be a multi-stage electric cylinder. The output of the linear actuator 8 The end is hinged with the hinge seat 7, and the top end of the slide bar 6 is rotatably installed with a tensioning wheel 9; a conveyor belt shaft 10 is installed on the tensioning wheel 9, and the conveyor belt shaft 10 is coaxially arranged with the tensioning wheel 9, and a conveyor belt shaft 2 11 is rotatably connected to the slide bar 6, and the conveyor belt shaft 2 11 is connected to the conveyor belt shaft 10 through a belt drive assembly, a friction wheel 12 is installed on the conveyor belt shaft 2 11, and a spring 13 is installed on the frame 1, and a friction block 14 is installed at the output end of the spring 13, and the friction block 14 is matched with the friction wheel 12.

[0022] In this embodiment, the polyester fabric passes between the two front squeezing rollers 2, passes above the slide bar 6, and finally passes between the two rear squeezing rollers 3. When the loose polyester fabric needs to be tensioned, the linear actuator 8 pushes the slide bar 6 through the hinge seat 7, so that the slide bar 6 can rotate along the rotating shaft 4 connected to the hollow sleeve 5. During the rotation, the slide bar 6 changes from an inclined state to a vertical state, so that the polyester fabric can be tensioned by raising the height of the tensioning wheel 9 at the top of the slide bar 6. During the rotation of the slide bar 6, the bottom of the slide bar 6 always contacts the frame 1, so that the tensioning wheel 9 at the top of the slide bar 6 gradually contacts and tensions the polyester fabric through rotation, while the slide bar 6 slides upward along the hollow sleeve 5 toward the polyester fabric, thereby further increasing the height of the tensioning wheel 9, and finally improving the tensioning effect on the polyester fabric; during the sliding During the gradual rotation of the rod 6, the friction wheel 12 abuts against the friction block 14 and squeezes the spring 13. The closer the slide rod 6 is to the vertical state, the greater the squeezing force on the spring 13, thereby the greater the squeezing force of the friction block 14 on the friction wheel 12. The conveyor belt shaft 11 connected to the friction wheel 12 and the conveyor belt shaft 10 connected to the tensioning wheel 9 are connected through a belt transmission assembly, so that the friction wheel 12 that is friction-braked makes it difficult for the tensioning wheel 9 that is driven to rotate when the full polyester cloth is transported to rotate, thereby further increasing the tensioning force on the full polyester cloth; when the spring 13 is squeezed and contracted, the spring 13 will bend due to the rotation of the friction wheel 12, but the hardness of the spring 13 can be increased to enable it to work normally.

[0023] In some embodiments, in order to reduce the friction between the bottom of the slide bar 6 and the frame 1 , a roller 15 is installed at the bottom end of the slide bar 6 , and the roller 15 is always in contact with the frame 1 .

[0024] In some embodiments, in order to further improve the braking effect on the friction wheel 12 , an arc-shaped groove 18 is provided on the friction block 14 .

[0026] In some embodiments, in order to facilitate the articulation between the linear actuator 8 and the articulated seat 7 , an articulated block 17 is installed at the output end of the linear actuator 8 , and the articulated block 17 is articulated with the articulated seat 7 .

[0027] In some embodiments, in order to prevent the friction block 14 from being easily damaged, a wear-resistant layer 19 is installed in the arc-shaped groove 18 .
