After the POY raw yarn is processed, multiple POY raw yarns can be passed through the corresponding support plate and inserted into the conical guide tube, the rotating tube and the guide tube and then fixed on the reel.

[0030] In the present invention, the movable clamping plate can be driven to move upward by rotating the screw rod. At this time, under the support and cooperation with the fixed clamping plate, multiple POY raw yarns can be clamped and positioned, so that when the rotating tube rotates, a torsional force can be applied to the multiple POY raw yarns, thereby twisting the POY raw yarns, so that POY wire materials can be produced;

[0031] In the present invention, the reel is driven to rotate by starting the driving motor, and the twisted POY wire can be wound up at this time.

[0046] Embodiment 1

[0047] Reference Fig. 9 A processing technology for preparing PET polyester DTY flexible cloth for battery current collector in this embodiment includes the following steps:

[0048] S1, cleaning the POY raw yarn;

[0049] S2, placing the cleaned POY raw yarn in a drying box for drying;

[0050] S3, sampling the dried POY raw yarn, and then putting it into a tensile testing machine to perform a performance test on the POY raw yarn;

[0051] S4, placing the tested POY raw yarns on the unwinding device in groups, and introducing one end of the plurality of POY yarns into the twisting machine 1 to perform a twisting process on the POY yarns;

[0052] S5, winding the POY wire after the twisting process.

[0053] Embodiment 2

[0054] Reference Figure 1-Figure 8 The twisting machine 1 is provided with an installation slot, and a drive motor 9 is fixedly installed on one side thereof to ensure that the output shaft of the drive motor 9 can extend into the installation slot. A collecting mechanism is installed in the installation slot, and a reel 14 is installed on the mechanism for winding the twisted POY wire.

[0055] Next, a straightening mechanism is installed on the top inner wall of the twisting machine 1, and its top extends to the top of the twisting machine 1 and is connected to the top. The main function of this mechanism is to straighten the POY wire before twisting to ensure that the wire has good compactness during twisting.

[0056] At the same time, a guiding mechanism is also installed on the top inner wall of the twisting machine 1, which is connected to the output shaft of the driving motor 9 and is used to guide the twisted POY wire material to ensure that it can be evenly wound on the reel 14. One side of the guiding mechanism is connected to the twisting mechanism, and when multiple POY wires pass through the mechanism, twisting can be performed.

[0057] In order to facilitate closing and opening the installation slot, the twisting machine 1 is located on one side of the installation slot opening and is rotatably connected to the door panel 2. A clamping shaft 4 is fixedly installed on one side of the door panel 2, and a clamping plate 3 is rotatably connected to one side of the twisting machine 1. A clamping opening is provided at the bottom of the clamping plate 3 for forming a clamping relationship with the clamping shaft 4.

[0058] In order to ensure the stable limit of the door panel 2, a limit plate 5 is fixedly installed on one side of the door panel 2, and a slidingly connected moving shaft 6 is penetrated through the limit plate 5. An arc-shaped baffle plate 7 is fixedly installed on the end of the moving shaft 6 close to the clamping plate 3, which is used to clamp and limit the clamping plate 3. A tension spring 8 located on one side of the limit plate 5 is sleeved on the moving shaft 6, and its two ends are fixedly connected to the end of the moving shaft 6 away from the arc-shaped baffle plate 7 and one side of the limit plate 5 respectively.

[0059] When the door panel 2 is used to seal the installation groove, the clamping plate 3 is first rotated to form a clamping relationship between the clamping shaft 4 and the clamping plate 3. During the rotation process, one side of the clamping plate 3 will contact the arc-shaped baffle 7. At this time, the downward thrust of the clamping plate 3 will drive the arc-shaped baffle 7 to move toward the side of the limit plate 5, so that the tension spring 8 is in a stressed and stretched state. After the clamping plate 3 and the clamping shaft 4 are completely clamped, the tension spring 8 in a stressed state will push the arc-shaped baffle 7 in the reverse direction to move, and the arc-shaped baffle 7 is used to form a clamping limit for the clamping plate 3, preventing the clamping plate 3 and the clamping shaft 4 from being arbitrarily separated from the clamping, thereby achieving the effect of stably limiting the door panel 2.

[0060] Reference Figure 8 The straightening mechanism includes a mounting frame 37 fixedly mounted on the top inner wall of the twisting machine 1, and a plurality of support plates 38 fixedly mounted at equal intervals on the bottom inner wall of the mounting frame 37. Next, a moving plate 39 is slidably connected in the mounting frame 37, and a plurality of pressing heads 40 are installed at equal intervals at the bottom of the moving plate 39. These pressing heads 40 are respectively matched with corresponding support plates 38 to press the POY wire before twisting, so as to ensure that the POY wire remains in a tight state before twisting.

[0061] Then, connect the top of the transmission assembly to the top of the twisting machine 1, and ensure that the top of the transmission assembly passes through the movable hole opened at the top of the twisting machine 1 and extends above it. In this way, when multiple POY wires are passed through the corresponding support plates 38 respectively, the movable plate 39 can be driven downward by driving the transmission assembly. When the movable plate 39 moves downward, it will drive multiple pressure heads 40 to move downward, so that the POY wires are clamped under the support and cooperation of the corresponding support plates 38. In this way, when twisting, the POY wires will be subjected to tension, thereby ensuring that the twisted POY wires remain in a tight state.

[0062] Next, the implementation of the transmission assembly is described in detail. A fixed plate 44 is fixedly installed on one side of the top of the twisting machine 1, and a drive shaft 45 is rotatably connected to the fixed plate 44. A rotating rod 43 is fixedly installed at one end of the drive shaft 45, and the bottom end of the rotating rod 43 passes through the movable hole and extends into the twisting machine 1. At the same time, a limit frame 41 is fixedly installed on the top of the movable plate 39, and a movable ring 42 is slidably sleeved on the limit frame 41. The bottom end of the rotating rod 43 is rotatably connected to the side of the movable ring 42.

[0063] In addition, a connecting ring 46 is fixedly installed at the other end of the driving shaft 45, and a threaded plate 47 is slidably connected to the top of the twisting machine 1. An adjusting screw rod 48 is threadedly connected to the threaded plate 47, and the adjusting screw rod 48 is ensured to be rotatably connected to the top of the twisting machine 1. Then, a stopper shaft 49 is fixedly installed on one side of the threaded plate 47 close to the connecting ring 46, and one end of the stopper shaft 49 passes through the connecting ring 46 and is transmission-connected to the inner wall of the connecting ring 46.

[0064] Then, two tension springs 50 are symmetrically fixedly connected at the top of the limit frame 41, and the top ends of the two tension springs 50 are fixedly connected to the top inner wall of the mounting frame 37. In this way, when it is necessary to adjust the pressing force of the pressure head 40 on the POY wire, the threaded plate 47 can be driven to move laterally by rotating the adjusting screw 48. At this time, when the stop shaft 49 moves laterally with the threaded plate 47, it will drive the connecting ring 46 to rotate downward. When the connecting ring 46 rotates, it will drive the rotating rod 43 to rotate downward through the driving shaft 45, thereby driving the moving ring 42 to move downward in an arc shape. Under the transmission action of the lateral sliding connection with the limit frame 41, the movement of the moving ring 42 will drive the moving plate 39 to move downward, and then drive the multiple pressure heads 40 to move downward, so as to achieve the pressing of the POY wire.

[0065] Reference Figure 7 The twisting mechanism is a tapered conduit 28 that penetrates the mounting plate 19 and ensures that it is fixedly connected to the mounting plate 19. One end of the tapered conduit 28 is used to connect a clamping assembly, the main function of which is to twist the POY wire.

[0066] Next, the driven gear 31 is connected to the clamping assembly, and the driving gear 30 is fixedly mounted on the rotating shaft 20. Ensure that the driving gear 30 is meshed with the driven gear 31, so that when the rotating shaft 20 rotates, the clamping assembly can be driven to operate through the meshing transmission of the driving gear 30 and the driven gear 31.

[0067] Then, the clamping assembly: the rotating tube 29 is rotatably connected to one end of the tapered guide tube 28, and the driven gear 31 is fixedly sleeved on the rotating tube 29. A fixed clamping plate 32 is fixedly installed on the top inner wall of the rotating tube 29, and a sliding connection moving frame 33 is penetrated on the bottom inner wall of the rotating tube 29.

[0068] A moving clamping plate 36 located in the rotating tube 29 is fixedly installed on the top of the moving frame 33, and a nut 35 is fixedly installed on the bottom of the moving frame 33. The screw rod 34 is threadedly connected in the nut 35, ensuring that the bottom end of the screw rod 34 extends to the bottom of the moving frame 33, and the top end of the screw rod 34 extends into the moving frame 33 and is rotatably connected to the bottom of the rotating tube 29.

[0069] When the POY wire needs to be clamped, the screw 34 can be rotated, and the screw 34 will drive the movable frame 33 to move upward under the thread transmission of the nut 35. In this way, the movable clamping plate 36 will also move upward in the rotating tube 29 to form a clamping match with the fixed clamping plate 32, thereby clamping the POY wire.

[0070] Finally, when the rotating tube 29 rotates along with the driven gear 31 , it twists the POY wire material clamped between the fixed clamping plate 32 and the movable clamping plate 36 , thereby achieving a twisting operation and improving the tightness of the POY wire material.

[0071] Embodiment 3

[0072] Reference Figure 1-Figure 6 , further improvement of the twisting machine 1 used for twisting the POY filament in Example 1: installation and setting of the collecting mechanism. The connecting disk 10 is fixedly mounted on the output shaft of the driving motor 9 to ensure a stable connection. A support shaft 11 is installed at the center position of one side of the connecting disk 10 so that it can rotate. A baffle 12 is fixedly sleeved on the support shaft 11, and a pressure plate 13 is connected by threads. The reel 14 is sleeved on the support shaft 11, located between the baffle 12 and the pressure plate 13, and in close contact with them. In this way, when the support shaft 11 rotates, the reel 14 will also rotate accordingly, so as to realize the winding of the twisted POY filament.

[0073] In order to facilitate the installation of the reel 14, one end of the support shaft 11 can be rotated to the outside of the mounting groove, and then rotated back after the installation. The threaded connection between the pressure plate 13 and the support shaft 11 can be used to press the reel 14 to ensure its stable rotation.

[0074] On one inner wall of the mounting groove, a support cover 15 is fixedly installed, and a support rod 16 is slidably connected therein. One end of the support rod 16 extends into the mounting groove, and a support cover 17 is fixedly installed therein. One end of the support shaft 11 extends into the support cover 17 to obtain stable support. A compression spring 18 is sleeved on the support rod 16, and its two ends are fixedly connected to the support cover 15 and the support cover 17 respectively. In this way, when the reel 14 is moved into the mounting groove, the support cover 17 can provide stable support for the support shaft 11 to prevent it from bending downward.

[0075] Next, the guide mechanism is installed and set. A rotating shaft 20 is rotatably connected to one side of the mounting plate 19, and a transmission roller 21 is fixedly sleeved thereon. A spiral annular groove is provided on the transmission roller 21, and a transmission ring 22 is sleeved thereon. A stopper is fixedly installed on the inner side of the transmission ring 22, and one side of the stopper extends into the annular groove and cooperates with the inner wall of the annular groove. In this way, when the rotating shaft 20 rotates, the transmission roller 21 can be driven to rotate, and then the transmission ring 22 is driven to reciprocate horizontally along the axial direction of the transmission roller 21 through the transmission cooperation between the annular groove and the stopper.

[0076] A guide tube 25 is fixedly installed at the bottom of the transmission ring 22 to guide the twisted POY wire. At the same time, a slide plate 23 is fixedly installed on the top of the transmission ring 22, and a sliding rod 24 is slidably connected thereon. The two ends of the sliding rod 24 are fixedly connected to the mounting plate 19 and the top inner wall of the twisting machine, respectively. In this way, when the transmission ring 22 performs a transverse reciprocating motion, the guide tube 25 will also move accordingly, ensuring that the twisted POY wire can be evenly wound on the reel 14.

[0077] Finally, the overall connection and drive setting are performed. The two transmission wheels 26 are respectively fixedly mounted on one end of the rotating shaft 20 and the output shaft of the driving motor 9, and are connected by a transmission belt 27. The twisting mechanism is respectively connected to the mounting plate 19 and the rotating shaft 20. In this way, when the driving motor 9 is working, its driving force is transmitted to the rotating shaft 20 through the transmission belt 27, thereby driving the entire guiding mechanism and the collecting mechanism to work, thereby realizing the twisting and winding of the POY filament.

[0078] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
