After searching, the prior art (Announcement No.: CN202322047740.8) is an insulating paper winding device. The article records that "by setting a damping unit and a transmission unit, the resistance of the paper roll fixing unit can be adjusted.

However, in the prior art, one end of the wound insulating paper accidentally loosens, causing the insulating paper to detach from the surface of the transmission unit, and it is difficult to effectively prevent the insulating paper from loosening and detaching. Utility Model Content

[0003] In order to overcome the defects of the prior art, an insulating paper winding device is now provided to solve the problem that one end of the wound insulating paper in the prior art accidentally loosens, causing the insulating paper to detach from the surface of the transmission unit, and it is difficult to effectively prevent the insulating paper from loosening and detaching.

[0004] To achieve the above object, an insulating paper winding device is provided, comprising: an insulating paper winding frame and a winding drum, wherein two sets of conveying rollers are axially connected to the inner side of the insulating paper winding frame, and a winding drum is installed on the right side of the insulating paper winding frame through a connecting frame.

[0005] A stop plate is arranged directly above the conveying roller, and the front and rear sides of the stop plate are connected to hydraulic columns through a fixed plate. A rubber pad is bonded to the lower surface of the stop plate, and adsorption holes are opened on the surface of the rubber pad. The upper end of the adsorption hole is connected to a negative pressure tube through a negative pressure cavity. A tension adjustment roller is arranged between the conveying rollers, and the front and rear sides of the tension adjustment roller are connected to the insulating paper winding frame through a guide shaft.

[0006] Furthermore, a transmission mechanism is installed on the front end surface of the insulating paper winding frame; and the transmission mechanism is connected to a conveying roller through a rotating shaft, and a connecting frame is welded on the right end of the insulating paper winding frame.

[0007] Furthermore, two sets of adjusting screws are installed in the front end groove of the connecting frame, and the surface of the adjusting screw is connected with a clamping plate through a screw nut; and the clamping plates are symmetrically distributed at the upper and lower ends of the winding drum.

[0008] Furthermore, a contact sensor is embedded and installed on the lower end surface of the clamping plate, and an adjusting column head is connected to the upper end of the adjusting screw; and the two groups of adjusting screws are connected and fixed via a connecting shaft.

[0009] Further, the front and rear sides of the tension adjusting roller are connected to the guide shaft through linear bearings; and an inductor is installed on the lower surface of the linear bearing, and a negative pressure pipe is connected to the rear side of the stop plate.

[0010] Further, a limit frame is welded on the upper surface of the insulating paper winding frame; and a fixing plate is connected in a limited manner within the limit frame, and a hydraulic column is fixedly embedded on the upper surface of the fixing plate.

[0011] Further, the stop plate, the hydraulic column, the negative pressure pipe, the rubber pad, and the adsorption holes constitute an anti-separation mechanism of the insulating paper winding frame.

[0012] The beneficial effect of the present utility model is that the insulating paper winding device of the present utility model utilizes the downward movement of the tension adjusting roller due to the disappearance of tension, so that the stop plate descends and presses on the surface of the conveying roller inside the winding device.

[0018] Referring to Figures 1 to 4 As shown, the present utility model provides an insulating paper winding device, including: an insulating paper winding frame 1 and a winding cylinder 4. Two groups of conveying rollers 13 are axially connected inside the insulating paper winding frame 1, and a winding cylinder 4 is installed on the right side of the insulating paper winding frame 1 through a connecting frame 41.

[0019] A stop plate 2 is arranged directly above the conveying roller 13, and the front and rear sides of the stop plate 2 are connected to the hydraulic column 21 through a fixed plate 26. A rubber pad 24 is bonded to the lower surface of the stop plate 2, and an adsorption hole 25 is opened on the surface of the rubber pad 24. The upper end of the adsorption hole 25 is connected to a negative pressure pipe 22 through a negative pressure chamber 23. A tension adjustment roller 5 is arranged between the conveying rollers 13, and the front and rear sides of the tension adjustment roller 5 are connected to the insulating paper winding frame 1 through a guide shaft 51.

[0020] First, the insulating paper is conveyed to the winding drum 4 by the rotating conveying roller 13, so that the winding drum 4 is driven by the motor to synchronously wind and reel the insulating paper. When one end of the insulating paper is accidentally loosened during the winding process, the tension-adjusting roller 5 falls due to the disappearance of tension, so that the sensor 52 senses that the tension-adjusting roller 5 has dropped to the lowest end, and the conveying roller 13 is controlled to stop rotating. The stop plate 2 moves down and presses on the surface of the conveying roller 13. At the same time, the negative pressure tube 22 causes the negative pressure chamber 23 and the adsorption hole 25 to generate negative pressure, and the insulating paper on the roller surface is adsorbed, thereby preventing the insulating paper from continuing to loosen and detaching from the surface of the conveying roller 13. The stop plate 2 that adsorbs the insulating paper is moved up, and the end of the insulating paper is manually adjusted to make the insulating paper rewound on the conveying roller 13 to continue conveying and winding the insulating paper.

[0021] In this embodiment, a transmission mechanism 12 is installed on the front end surface of the insulating paper winding frame 1; and the transmission mechanism 12 is connected to a conveying roller 13 through a rotating shaft, and a connecting frame 41 is welded to the right end of the insulating paper winding frame 1.

[0022] As a preferred implementation, the transmission mechanism 12 drives the two groups of conveying rollers 13 to rotate synchronously to convey the insulating paper passing through the upper surface of the conveying rollers 13 .

[0023] In this embodiment, two sets of adjusting screws 32 are installed in the front end groove of the connecting frame 41, and the surfaces of the adjusting screws 32 are connected with clamping plates 3 through screw nuts; and the clamping plates 3 are symmetrically distributed at the upper and lower ends of the winding drum 4. A contact sensor is embedded and installed on the lower end surface of the clamping plate 3, and the upper end of the adjusting screw 32 is connected with an adjusting column head 31; and the two sets of adjusting screws 32 are fixed relative to each other through a connecting shaft.

[0024] As a preferred embodiment, the adjusting column head 31 drives the two sets of adjusting screws 32 to rotate, so that the screw nut on the surface of the adjusting screw 32 converts the rotational motion into linear motion, thereby adjusting the distance between the clamping plate 3 and the clamping plate 3, so that the clamping plate 3 plays the role of limiting the number of winding turns or clamping the insulating paper on the surface of the winding drum 4.

[0025] In this embodiment, the front and rear sides of the tension adjusting roller 5 are connected to the guide shaft 51 through linear bearings; and an inductor 52 is installed on the lower surface of the linear bearing, and a negative pressure pipe 22 is connected to the rear side of the stop plate 2. A limiting frame 11 is welded on the upper surface of the insulating paper winding frame 1; and a fixing plate 26 is connected in a limiting manner within the limiting frame 11, and a hydraulic column 21 is embedded and fixed on the upper surface of the fixing plate 26.

[0026] As a preferred embodiment, the insulating paper passes through the lower roller surface of the tension adjusting roller 5. Through the change in the tension during the winding and conveying of the insulating paper, the tension adjusting roller 5 moves up and down on the surface of the guide shaft 51, thereby achieving the effect of automatically adjusting the winding tension of the insulating paper. The hydraulic column 21 is used to push the stop plate 2 to move up and down.

[0027] In this embodiment, the stop plate 2, the hydraulic column 21, the negative pressure pipe 22, the rubber pad 24, and the adsorption holes 25 constitute the anti-separation mechanism of the insulating paper winding frame 1.

[0028] As a preferred embodiment, the anti-separation mechanism of the insulating paper winding frame 1 is convenient for effectively preventing the wound insulating paper from loosening and detaching continuously, avoiding the loosening of the wound and coiled insulating paper, saving the processing time of abnormal loosening and rewinding, and improving the winding efficiency of the winding device.

[0029] The insulating paper winding device of the present utility model can effectively solve the problem of difficultly preventing the loosening and detachment of the insulating paper, is convenient for effectively preventing the wound insulating paper from loosening and detaching continuously, avoiding the loosening of the wound and coiled insulating paper, saving the processing time of abnormal loosening and rewinding, improving the winding efficiency of the winding device, and is applicable to the insulating paper winding device.
