[0026] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings: Example

[0027] A winding device includes a frame 100, which is equipped with: a clutch 210, the power input end of which is connected to the motor 230, and the power output end of which is connected to the winding roller 220; a brake 310, which is connected to the placement roller 320; a first control unit 410, which is communicated with the clutch 210; a second control unit 420, which is communicated with the brake 310; and a frequency conversion unit 430, which is communicated with the motor 230.

[0028] Specifically, such as Figure 1 As shown, the clutch 210 is a magnetic powder clutch, and the brake 310 is a magnetic powder brake.

[0029] The first control unit 410 may be a first controller, the second control unit 420 may be a second controller, and the frequency conversion unit 430 may be a frequency converter;

[0030] In some embodiments, the first control unit 410 , the second control unit 420 , and the frequency conversion unit 430 may be integrated into a control system in the form of a single controller.

[0031] When in use, the frequency conversion unit 430 outputs voltage to the motor 230, and the first control unit 410 outputs voltage to the clutch 210. The motor 230 rotates to drive the clutch 210 and the winding roller 220 to rotate; at the same time, the second control unit 420 outputs current to the brake 310, and the brake 310 drives the placement roller 320 to rotate. The brake 310 is used to brake to adjust the tension of the material on the placement roller 320; through the cooperation of the first control unit 410, the second control unit 420 and the frequency conversion unit 430 with the placement roller 320 and the winding roller 220, the rotation speed of the placement roller 320 and the winding roller 220 is coordinated to keep the tension constant.

[0032] The frame 100 includes a first end plate 110 and a second end plate 120. The inner sides of the first end plate 110 and the second end plate 120 form an accommodating space 100a, and the clutch 210 and the brake 310 are located in the accommodating space 100a; a through opening 111 is constructed on the first end plate 110, and the winding roller 220 and the placing roller 320 are placed outside the accommodating space 100a through the through opening 111.

[0033] Specifically, such as Figure 1 As shown, the first end plate 110 on the left and the second end plate 120 on the right are arranged in parallel. The space between the inner end (right end) of the first end plate 110 and the inner end (left end) of the second end plate 120 is the accommodating space 100a. The clutch 210 and the brake 310 are both located in the accommodating space 100a. The protective structure formed by the first end plate 110 and the second end plate 120 ensures the safety of the clutch 210 and the brake 310 in the accommodating space.

[0034] Further, such as Figure 1 As shown, a protective rod 150 is provided at the corner positions of the first end plate 110 and the second end plate 120, and the left and right ends of the protective rod 150 are respectively connected to the first end plate 110 and the second end plate 120. The protective rod 150 located at the corner position is matched with the first end plate 110 and the second end plate 120 to form a relatively safe accommodating space 100a while ensuring structural stability.

[0035] like Figure 2 As shown, a through opening 111 is constructed on the first end plate 110. In some embodiments, there are two through openings 111, corresponding to the position of the clutch 210 and the position of the brake 310 respectively, so that the winding roller 220 connected to the clutch 210 can extend to the outer end of the first end plate 110, that is, extend out of the accommodating space 100a, and operate outside the accommodating space 100a; the winding roller 220 connected to the brake 310 can extend to the outer end of the first end plate 110, that is, extend out of the accommodating space 100a.

[0036] In some embodiments, the through opening 111 can also be set as a larger opening, that is, the winding roller 220 and the placing roller 320 both extend from the through opening 111 to the outer end of the first end plate 110, that is, extend out of the accommodating space 100a, and operate outside the accommodating space 100a.

[0037] The motor 230 is installed outside the second end plate 120 , and the output end of the motor 230 is placed in the accommodating space 100 a . The output end of the motor 230 is transmission-connected to the input end of the clutch 210 in the accommodating space 100 a .

[0038] Specifically, such as Figure 1 As shown, the motor 230 is installed at the outer end of the second end plate 120, and the output end of the motor 230 enters the accommodating space 100a. The output end of the motor 230 is a first pulley, which is connected to the second pulley at the input end of the clutch 210 through a belt. It can be understood that the transmission unit formed by the first pulley, the second pulley and the belt is located in the accommodating space 100a, which can effectively prevent the staff from contacting the transmission unit during misoperation, thereby improving the safety of use.

[0039] The frame 100 further includes a third end plate 130 , and the brake 310 is connected to the third end plate 130 ; a sliding rod 140 is connected between the first end plate 110 and the second end plate 120 , and the third end plate 130 is slidably connected to the sliding rod 140 .

[0040] Specifically, such as Figure 2 As shown, the third end plate 130 is located between the first end plate 110 and the second end plate 120, and the first end plate 110, the second end plate 120 and the third end plate 130 are arranged in parallel; the sliding rod 140 is connected between the first end plate 110 and the second end plate 120, and the third end plate 130 is connected with a sliding bearing 131 to be slidably connected to the sliding rod 140, and the brake 310 is located on the third end plate 130, so that the position of the placement roller 320 can be fine-tuned.

[0041] There are no less than three sliding rods 140 to form a stable support structure to ensure the stability of the third end plate 130 and the brake 310 .

[0042] like Figure 2 As shown, the sliding rods 140 include four sliding rods 140 , which are arranged in a square shape at the four corners of the third end plate 130 .

[0043] The telescopic member 520 and the driving rod 510 are further included. The telescopic member 520 is connected to the third end plate 130 . The driving rod 510 is in transmission connection with the telescopic member 520 so as to drive the telescopic member 520 to change in length.

[0044] The driving rod 510 is connected to the telescopic member 520 through a bevel gear transmission. A bearing block 121 is further configured at the outer end of the second end plate 120 , and the driving rod 510 is rotatably connected to the bearing block 121 .

[0045] like Figure 2 As shown, the telescopic member 520 can be a double-tube structure with threaded connection, which belongs to the existing technology and will not be elaborated. One end of the telescopic member 520 is rotatably connected to the second end plate 120, and the exposed end plate position is connected to the first bevel gear 530, and the other end is connected to the third end plate 130; the outer end of the second end plate 120 is also connected to the supporting block 121, the driving rod 510 is rotatably connected to the supporting block 121, and one end of the driving rod 510 is a handle, and the other end is a second bevel gear 540. The first bevel gear 530 is engaged with the second bevel gear 540, and then the handle is rotated, which can drive the first bevel gear 530 to rotate through the second bevel gear 540, thereby adjusting the length of the telescopic member 520, and achieving the purpose of fine-tuning the position of the third end plate 130 and the brake 310.

[0046] like Figure 1 As shown, the frame 100 is also rotatably connected to a tension roller 160 , and the winding roller 220 , the placement roller 320 and the tension roller 160 are parallel to each other and arranged in a triangle. Example

[0047] It includes two corresponding frames 100, specifically, Figure 3 As shown, the two frames 100 are symmetrically arranged. Similarly, the clutch 210, brake 310, placement roller 320 and winding roller 220 installed on the two frames 100 are also symmetrically arranged. The first end plates 110 of the two frames 100 can be connected by a connecting rod, so that two groups of winding units work at the same time.

[0048] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
