[0026] 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.

[0027] See also Figure 1 , Figure 1A front view of a device for quickly dividing and cutting crepe paper into equal parts provided by an embodiment of the present invention.

[0028] The embodiment of the present invention discloses a device for quickly dividing and cutting crepe paper into equal parts. The device comprises a mounting mechanism 1 and a winding mechanism 2.

[0029] Among them, the mounting mechanism 1 includes a first support seat and a mounting shaft 120 detachably arranged on the first support seat, the mounting shaft 120 can be fixed relative to the first support seat, or the mounting shaft 120 can be rotated relative to the first support seat. When the crepe paper needs to be cut, the mounting shaft 120 is first removed from the first support seat, the crepe paper disc is sleeved on the mounting shaft 120, and then the mounting shaft 120 is returned to the first support seat. The winding mechanism 2 includes a second support seat and a winding wheel 220 rotatably arranged on the second support seat, and a positioning and cutting groove 221 is arranged on the circumferential surface of the winding wheel 220. The positioning and cutting groove 221 extends along the axial direction of the winding wheel 220 and penetrates the winding wheel 220 along the axial direction. The positioning and cutting groove 221 can be a V-shaped groove, a U-shaped groove or an inverted trapezoidal groove, and the winding wheel 220 can be driven manually or by a motor.

[0030] Compared with the prior art, the crepe paper quick equal division and cutting device provided in the embodiment of the present invention is used. According to the required length of crepe paper, a winding wheel 220 of corresponding circumference is used, and then the crepe paper wheel is inserted into the mounting shaft 120, and then one end of the crepe paper is aligned with the positioning and cutting groove 221 and fixed on the winding wheel 220. According to the required number of fixed-length crepe papers, the winding wheel 220 is rotated for a preset number of turns. Since the crepe paper is relatively thin, the circumference of each turn after winding multiple turns is basically the same. The crepe paper is cut at the positioning and cutting groove 221, so as to obtain crepe paper of the required length. By using the above-mentioned crepe paper quick equal division and cutting device, multiple pieces of crepe paper of basically the same length can be quickly obtained, and the cutting efficiency is high, which can improve the production efficiency of transformers.

[0031] In actual application, the crepe paper between the mounting mechanism 1 and the winding mechanism 2 will sag due to gravity, which will affect the winding effect of the winding mechanism 2. Therefore, in one embodiment of the present application, Figure 1 As shown, the crepe paper quick equal-division and cutting device also includes a support mechanism 3, which includes a third support seat and a support roller 320 rotatably arranged on the third support seat. The support mechanism 3 is arranged between the mounting mechanism 1 and the winding mechanism 2. The support roller 320 is used for rolling and supporting the crepe paper between the mounting mechanism 1 and the winding mechanism 2. The support mechanism 3 provides support for the crepe paper between the mounting mechanism 1 and the winding mechanism 2 to prevent the crepe paper from sagging excessively and ensure the normal winding of the winding mechanism 2.

[0032] In order to facilitate the movement of the crepe paper quick-dividing and cutting device, so as to facilitate the operation when insulating and wrapping the leads of different transformers, in one embodiment of the present application, as Figure 1 and Figure 2 As shown, the crepe paper quick equal-dividing and cutting device also includes a moving trolley 4, the mounting mechanism 1, the winding mechanism 2 and the supporting mechanism 3 are all arranged on the moving trolley 4, the moving trolley 4 includes a body 410 and four rollers 420 arranged under the body 410, at least two of the four rollers 420 are universal wheels, and at least two of the rollers 420 are provided with a stopping device to achieve stable positioning of the moving trolley 4, and the mounting mechanism 1, the winding mechanism 2 and the supporting mechanism 3 are all arranged on the body 410.

[0033] To facilitate the installation and disassembly of the mounting shaft 120, in one embodiment of the present application, Figure 1 As shown, the first support seat includes two first support plates 110 arranged opposite to each other, and a downwardly inclined mounting groove 111 is arranged on the side of the first support plate 110 away from the winding mechanism 2, and the two ends of the mounting shaft 120 are rotatably engaged with the mounting grooves 111 on the two first support plates 110 respectively. When in use, when it is necessary to disassemble or assemble the mounting shaft 120, the mounting shaft 120 can be taken out or put in along the direction of the mounting groove 111. During the winding process, due to the inclined setting of the mounting groove 111, under the action of its own gravity and the tension of the crepe paper, the mounting shaft 120 can be stably maintained in the mounting groove 111 and cannot fall out of the mounting groove 111.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the second support seat includes two second support plates 210 that are oppositely disposed, and the winding wheel 220 is rotatably disposed between the two second support plates 210 .

[0035] In order to ensure that the crepe paper remains stable during the winding process, in one embodiment of the present application, Figure 1 and Figure 2 As shown, limiting baffles 222 are respectively provided on the axial side surfaces of the winding wheel 220. Multiple limiting baffles 222 can be provided along the circumference of the winding wheel 220. The positioning and cutting grooves 221 are located between two adjacent limiting baffles 222. The limiting baffles 222 can also be an integrated structure in the circumference of the winding wheel 220. In this case, it is necessary to leave an avoidance space at the position of the positioning and cutting grooves 221 to facilitate the cutting operation. The two limiting baffles 222 on the axial side surfaces of the winding wheel 220 cooperate with each other to limit the crepe paper wound on the winding wheel 220.

[0036] like Figure 1As shown, in one embodiment of the present application, the third support seat includes two third support plates 310 arranged opposite to each other, the support roller 320 is rotatably arranged between the two third support plates 310, and the third support plate 310 is arranged on the moving vehicle 4 through the first support plate 110.

[0037] It should be noted that the structure of the above-mentioned first support seat, the second support seat and the third support seat is only a preferred implementation scheme provided in the present application, and is not actually limited to the above-mentioned structure. As long as it can provide stable support for the installation shaft 120, the support roller 320 and the winding wheel 220, no limitation is made here.

[0038] like Figure 2 As shown, in one embodiment of the present application, the winding mechanism 2 also includes a winding drive device 230, the winding drive device 230 is arranged on the second support seat, and the winding drive device 230 is transmission-connected to the winding wheel 220, and the winding drive device 230 drives the winding wheel 220 to rotate. Specifically, the winding drive device 230 is a motor.

[0039] Preferably, in one embodiment of the present application, the crepe paper rapid equal-division and cutting device further comprises a cutting mechanism, which is disposed on a second support seat, and comprises a cutting knife and a cutting drive device, which is transmission-connected to the cutting knife to drive the cutting knife to reciprocate along the radial direction of the winding wheel 220 to cut the crepe paper on the winding wheel 220. When the winding wheel 220 rotates a preset number of circles and the positioning cutting groove 221 is opposite to the blade of the cutting knife, the production staff can control the cutting mechanism to perform cutting.

[0040] To further optimize the above technical solution, the crepe paper rapid equal-division and cutting device also includes a control system, which includes a controller, a counting device and an angle sensor. The counting device is used to detect the number of rotations of the winding wheel 220, and the angle sensor is used to detect the angle of the winding wheel 220, so that the controller can obtain the current position of the winding wheel 220, so as to control the positioning and cutting groove 221 relative to the blade of the cutting knife. The controller is respectively communicated with the counting device, the angle sensor, the winding drive device 230 and the cutting drive device. The controller is used to control the winding drive device 230 to rotate the winding turntable to the position where the positioning and cutting groove 221 is relative to the cutting knife according to the detection value of the angle sensor after the winding wheel 220 rotates a preset number of times, and control the action of the cutting drive device. In this way, the crepe paper rapid equal-division and cutting device can realize automatic cutting of crepe paper, further improve cutting efficiency, and reduce work intensity.

[0041] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
