[0018] S2: Then the motor is controlled to start, the start of the motor drives the rotation of the first rotating shaft, the rotation of the first rotating shaft drives the winding roller to rotate to wind up the polyester cloth, and at the same time, the rotation of the first rotating shaft drives the rotation of the second rotating shaft through the pulley group, the rotation of the second rotating shaft drives the rotation of the first gear, the rotation of the first gear drives the rotation of the second gear, the rotation of the second gear drives the rotation of the third gear, the rotation of the third gear drives the rotation of the fourth rotating shaft, the rotation of the fourth rotating shaft drives the rotation of the worm, the rotation of the worm drives the rotation of the worm wheel, the rotation of the worm wheel drives the rotation of the fifth rotating shaft, the rotation of the fifth rotating shaft drives the fixed block to move upward, the movement of the fixed block drives the movement of the second moving block, the movement of the second moving block drives the movement of the threaded rod, the movement of the threaded rod drives the movement of the first moving block, so that the two pressure rollers move synchronously to maintain a certain tension to wind up the polyester cloth;

[0019] S3: After winding, the fourth rotating shaft is driven to rotate by rotating the second rotating block. Similarly, the rotation of the fourth rotating shaft drives the fixed block to move, so that the two pressure rollers move downward and reset.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention sets a tension component. When the polyester cloth is rolled up during production, first one end of the polyester cloth is passed through two pressure rollers and installed on the outer wall of the winding roller. Then the motor is controlled to start. The start of the motor drives the rotation of the first rotating shaft. The rotation of the first rotating shaft drives the winding roller to rotate so as to roll up the polyester cloth. During the rolling process, the two pressure rollers contact the two sides of the polyester cloth, and apply appropriate tension and pressure to the polyester cloth, which helps to smooth out the wrinkles and uneven parts on the surface of the fabric, so that the rolled polyester cloth is smoother and more beautiful, thereby improving the production quality of the polyester cloth.

[0022] 2.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 6 As shown, in an embodiment of the present invention, a winding device for producing polyester cloth includes a device body 1, a side plate 2 is fixedly installed on the top of the device body 1, a winding roller 3 is arranged above the device body 1, a tension assembly is arranged on one side of the winding roller 3, both ends of the winding roller 3 are fixedly connected with a first rotating shaft 4, one end of one of the first rotating shafts 4 is rotatably connected with a control panel 6, and one end of the other first rotating shaft 4 is installed with a motor 5, and the motor 5 is arranged inside the device body 1;

[0033] Among them, the tension component includes a pressure roller 7 arranged on one side of the winding roller 3, and there are two pressure rollers 7. One end of the two pressure rollers 7 is fixedly connected to a connecting shaft 8, and one end of the two connecting shafts 8 is respectively installed with a first moving block 9 and a second moving block 10, an adjustment component is arranged between the first moving block 9 and the second moving block 10, and a moving component is arranged on one side of the second moving block 10.

[0034] When the polyester cloth is produced and rolled up, first one end of the polyester cloth is passed through two pressure rollers 7 and installed on the outer wall of the winding roller 3, and then the motor 5 is controlled to start. The start of the motor 5 drives the rotation of the first rotating shaft 4, and the rotation of the first rotating shaft 4 drives the winding roller 3 to rotate to roll up the polyester cloth. During the rolling process, the two pressure rollers 7 contact both sides of the polyester cloth, and apply appropriate tension and pressure to the polyester cloth, which helps to smooth out the wrinkles and uneven parts on the surface of the fabric, making the rolled polyester cloth smoother and more beautiful, thereby improving the production quality of the polyester cloth.

[0035] like Figure 6 As shown, the pressure roller 7 and the connecting shaft 8 are rotationally connected.

[0036] During the process of winding the polyester cloth, the polyester cloth passes between the two pressing rollers 7, and the friction between the two rollers can cause the pressing rollers 7 to rotate. The rotation not only helps the polyester cloth to remain flat and prevent wrinkles or curling during transportation, but also helps prevent the polyester cloth from being broken or damaged due to excessive tension, thereby ensuring the integrity of the material and the processing quality.

[0037] like Figure 5 and Figure 6As shown, the adjustment assembly includes a threaded rod 11 installed on the top of the second moving block 10, the threaded rod 11 is embedded in the first moving block 9 and threadedly connected, and the top of the threaded rod 11 is fixedly mounted with a first rotating block 12, which is arranged above the side panel 2.

[0038] When the polyester cloth needs to be rolled up, the threaded rod 11 is driven to rotate by rotating the first rotating block 12, the rotation of the threaded rod 11 drives the movement of the first moving block 9, the movement of the first moving block 9 drives the movement of the connecting shaft 8, and the movement of the connecting shaft 8 drives the movement of the pressing roller 7, so that the distance between the two pressing rollers 7 changes, which can not only adapt to the rolling of polyester cloths of different thicknesses, but also adjust the pressure applied by the pressing roller 7 to the polyester cloth, thereby further improving the production quality of the polyester cloth.

[0039] like Figure 5 and Figure 6 As shown, the second moving block 10 is rotationally connected to the threaded rod 11 .

[0040] like Figure 2 As shown, the threaded rod 11 is slidably connected to the side plate 2 .

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the moving assembly includes a fixed block 23 fixedly mounted on the side wall of the second moving block 10, the inner wall of the fixed block 23 is threadedly connected with the fifth rotating shaft 22, the bottom end of the fifth rotating shaft 22 is connected with the fourth rotating shaft 19 through a transmission assembly, the outer wall of the fourth rotating shaft 19 is fixedly mounted with a third gear 18, one side of the third gear 18 is meshedly connected with the second gear 16, the inside of the second gear 16 is fixedly mounted with a third rotating shaft 17, one side of the second gear 16 is meshedly connected with the first gear 15, the inner wall of the first gear 15 is fixedly mounted with the second rotating shaft 14, the outer wall of the second rotating shaft 14 is mounted with a pulley group 13, and the end of the pulley group 13 away from the second rotating shaft 14 is mounted on the outer wall of the first rotating shaft 4.

[0042] When the winding roller 3 rotates to wind up the polyester cloth, the first rotating shaft 4 rotates and drives the second rotating shaft 14 to rotate through the pulley group 13. The rotation of the second rotating shaft 14 drives the rotation of the first gear 15. The rotation of the first gear 15 drives the rotation of the second gear 16. The rotation of the second gear 16 drives the rotation of the third gear 18. The rotation of the third gear 18 drives the rotation of the fourth rotating shaft 19. The fourth rotating shaft 19 rotates and is connected through the transmission component to rotate the fifth rotating shaft 22. The rotation of the fifth rotating shaft 22 drives the fixed block 23 to move upward. The movement of the fixed block 23 drives the movement of the second moving block 10. The movement of the second moving block 10 drives the movement of the threaded rod 11. The movement of the threaded rod 11 drives the movement of the first moving block 9, so that the two pressing rollers 7 move synchronously to prevent the tension between the two pressing rollers 7 and the polyester cloth from changing as the thickness of the winding gradually increases during the process of winding the polyester cloth. The polyester cloth will be broken or damaged due to excessive tension. The height of the two pressing rollers 7 changes with the thickness of the winding polyester cloth, which helps to keep the tension of the polyester cloth stable during the winding process.

[0043] like Figure 3 and Figure 4 As shown, the transmission assembly includes a worm wheel 21 fixedly mounted on the bottom end of the fifth rotating shaft 22 , one side of the worm wheel 21 is meshingly connected with a worm 20 , and the worm 20 is fixedly connected to the fourth rotating shaft 19 .

[0044] When the fourth rotating shaft 19 rotates, the worm 20 is driven to rotate, the rotation of the worm 20 drives the rotation of the worm wheel 21, and the rotation of the worm wheel 21 drives the rotation of the fifth rotating shaft 22, thereby driving the pressure roller 7 to move. The transmission through the worm 20 and the worm wheel 21 has self-locking properties, preventing the fixed block 23 from moving downward due to the gravity of the pressure roller 7 and causing instability.

[0045] like Figure 3 and Figure 4 As shown, the first gear 15 is configured as a sector gear.

[0046] The inner diameter of the first gear 15 is smaller than the inner diameter of the second gear 16, and the inner diameter of the second gear 16 is smaller than the inner diameter of the third gear 18. The sizes of the three gears increase gradually, so that the moving speed of the pressure roller 7 is smaller than the winding speed.

[0047] By setting the first gear 15 in a sector shape, the power transmitted by the first gear 15 can be further changed, so that the first gear 15 rotates N circles to drive the second gear 16 to rotate one circle, so that the pressure roller 7 moves slowly to ensure stable tension;

[0048] like Figure 4 As shown, a second rotating block 24 is fixedly mounted on one end of the fourth rotating shaft 19 , and the second rotating block 24 is arranged on one side of the side plate 2 .

[0049] After the polyester cloth is rolled up, the fourth rotating shaft 19 is driven to rotate by rotating the second rotating block 24. Similarly, the rotation of the fourth rotating shaft 19 drives the fixed block 23 to move, so that the two pressing rollers 7 move downward and reset to facilitate subsequent rolling.

[0050] A winding method for a winding device for producing polyester cloth comprises the following steps:

[0051] S1: When the polyester fabric is produced and rolled up, firstly, one end of the polyester fabric is passed through two pressing rollers 7 and installed on the outer wall of the winding roller 3, and then the distance between the two pressing rollers 7 is adjusted according to the thickness of the polyester fabric, and the first rotating block 12 is rotated to drive the threaded rod 11 to rotate, and the rotation of the threaded rod 11 drives the movement of the first moving block 9, and the movement of the first moving block 9 drives the movement of the connecting shaft 8, and the movement of the connecting shaft 8 drives the movement of the pressing roller 7, so that the distance between the two pressing rollers 7 is changed and adjusted;

[0052] S2: Then the motor 5 is controlled to start, the start of the motor 5 drives the rotation of the first rotating shaft 4, the rotation of the first rotating shaft 4 drives the winding roller 3 to rotate to wind up the polyester cloth, and at the same time, the rotation of the first rotating shaft 4 drives the rotation of the second rotating shaft 14 through the pulley group 13, the rotation of the second rotating shaft 14 drives the rotation of the first gear 15, the rotation of the first gear 15 drives the rotation of the second gear 16, the rotation of the second gear 16 drives the rotation of the third gear 18, the rotation of the third gear 18 drives the rotation of the fourth rotating shaft 19, the rotation of the fourth rotating shaft 19 drives the rotation of the worm 20, the rotation of the worm 20 drives the rotation of the worm wheel 21, the rotation of the worm wheel 21 drives the rotation of the fifth rotating shaft 22, the rotation of the fifth rotating shaft 22 drives the fixed block 23 to move upward, the movement of the fixed block 23 drives the movement of the second moving block 10, the movement of the second moving block 10 drives the movement of the threaded rod 11, the movement of the threaded rod 11 drives the movement of the first moving block 9, so that the two pressing rollers 7 move synchronously to maintain a certain tension to wind up the polyester cloth;

[0053] S3: After winding, the fourth rotating shaft 19 is driven to rotate by rotating the second rotating block 24. Similarly, the rotation of the fourth rotating shaft 19 drives the fixed block 23 to move, so that the two pressing rollers 7 move downward and reset.
