[0038] Embodiment 4, as Figure 4 and Figure 5 As shown, the present invention proposes a low dielectric glass fiber cloth desizing and winding device.

Torsion springs 29 are arranged on the rotating shafts of the upper pressure plate 27 and the lower pressure plate 28, and the torsion springs are connected to the side frame 19. The upper pressure plate 27 and the lower pressure plate 28 are both in a downward pressure state in a natural state. The upper pressure plate 27 and the lower pressure plate 28 are respectively an external pressure component and an internal pressure component. A state adjustment module is arranged on the outer peripheral wall of the sleeve 18 to change the state of the upper pressure plate 27 and the lower pressure plate 28.

[0040] Furthermore, the state adjustment module includes a fixed ring 20 arranged at the bottom of the side frame 19, a sliding ring 22 slidably sleeved on the sleeve 18, a spring 21 arranged between the fixed ring 20 and the sliding ring 22, and an electric telescopic rod 23 arranged on the sliding frame 7, and the end of the electric telescopic rod 23 is in contact with the sliding ring 22; a vertical plate 24 is arranged on the sliding ring 22, and an upper push rod 25 and a lower push rod 26 are respectively arranged on the upper and lower parts of the vertical plate 24, the upper push rod 25 presses against the bottom of the upper pressure plate 27 to make it flip, and the lower push rod 26 presses against the bottom of the lower pressure plate 28 to make it flip; the control system is connected to the control of the electric telescopic rod 23, and an independent power supply is arranged in the box body 6 to power the electric telescopic rod 23. When the electric telescopic rod 23 is extended to the maximum length, the sliding ring 22 moves inward. The upper and lower pressure plates 27 and 28 are both in the open state. After the electric telescopic rod 23 is retracted for a certain distance, the lower pressure plate 28 rotates to the downward pressure state under the action of the torsion spring 29. The upper pressure plate 27 also flips a certain angle but is still in the open state. After the electric telescopic rod 23 is retracted to the maximum extent, the upper pressure plate 27 also enters the downward pressure state, that is, when the electric telescopic rod 23 is fully retracted, the upper and lower pressure plates 27 and 28 are both pressed downward, which is suitable for completing the winding of the cloth roll 30. When the electric telescopic rod 23 is partially extended, the lower pressure plate 28 is pressed downward, and the upper pressure plate 27 is opened, which is suitable for the winding mechanism at the winding position. When the electric telescopic rod 23 is fully extended, the upper and lower pressure plates 27 and 28 are both opened, which is suitable for the winding mechanism at the waiting position.

[0041] Embodiment 5, as Figure 4 and Figure 5 As shown, the present invention proposes a low dielectric glass fiber cloth desizing and winding device. Compared with the fourth embodiment, this embodiment introduces the structure of the cutting mechanism in detail.

[0042] The cutting mechanism includes a cutting support frame 33 slidably arranged on the base 1, a cutting device 32 arranged on the cutting support frame 33, and a rodless cylinder 34 arranged on the base 1, and the rodless cylinder 34 drives the cutting support frame 33 to move. In an optional embodiment, the cutting device 32 includes a support plate arranged on the cutting support frame 33, an electric push rod vertically arranged at the bottom of the support plate, a cutter arranged at the bottom of the electric push rod, and a cutting support plate arranged on the cutting support frame 33 and located below the cutter, and a knife groove for inserting the cutter is arranged on the cutting support frame 33. When the cloth roll 30 is rolled up and the side frame 19 at the rolling position is rotated to a horizontal state, the cutter and the knife groove move to the upper and lower sides of the glass fiber cloth 31, and then the electric push rod pushes the cutter downward to cut the glass fiber cloth. While cutting, the lower pressure plate 28 at the waiting position presses the glass fiber cloth 3 1. After the cutting is completed, the central axis 16 of the waiting position starts to rotate for winding. After the glass fiber cloth 31 is cut, the cutting mechanism is reset, and the central axis 16 of the winding position rotates ninety degrees and then stops rotating. At this time, the cloth head of the winding position is located at the top of the cloth roll 30, and the side frame 19 is just rotated to a vertical state. The upper pressure plate 27 presses the cloth head to prevent the cloth head of the cloth roll 30 from loosening after winding. When the winding drum 17 and the cloth roll 30 are subsequently packaged, the sleeve 18 is removed, and the cloth head is pressed by the upper pressure plate 27 during the time from the completion of winding to the packaging. After packaging, the cloth head is fixed by the packaging material to ensure the fixation of the cloth head throughout the whole process.

[0043] In summary, when the present invention is in use, the central shaft 16 at the waiting position on the rotating frame 4 does not rotate, the side frame 19 is vertically upward, and the central shaft 16 and the winding drum 17 at the winding position rotate to perform winding. When the cloth roll 30 is wound up and the side frame 19 of the winding position is rotated to a horizontal state, the cutter and the knife groove move to the upper and lower sides of the glass fiber cloth 31, and then the electric push rod pushes the cutter down to cut the glass fiber cloth. At the same time, the lower pressure plate 28 of the waiting position presses the glass fiber cloth 31. After the cutting is completed, the cutting mechanism is reset, and the central axis 16 of the waiting position starts to rotate for winding, and the central axis 16 of the winding position stops rotating after rotating ninety degrees. At this time, the cloth head of the winding position is located at the top position of the cloth roll 30, and the side frame 19 just rotates to a vertical state, and the upper pressure plate 27 presses the cloth head to prevent the cloth head of the wound cloth roll 30 from loosening. When the winding drum 17 and the cloth roll 30 are subsequently packaged, the sleeve 18 is removed, and the cloth head is pressed by the upper pressure plate 27 during the time from the completion of winding to the packaging. After packaging, the cloth head is fixed by the packaging material to ensure the fixation of the cloth head throughout the process. The winding mechanism at the waiting position rotates to the transition position, and the winding mechanism at the winding position rotates to the unloading position for unloading. After unloading, the winding drum 17 and the sleeve 18 are installed, and the rotating frame 4 continues to rotate ninety degrees to continue the winding work.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
