Description

Technical Field

[0001] This utility model relates to the field of tensioning mechanism technology, and in particular to a rotary three-way quick wheel changing mechanism. Background Technology

[0002] During the processing of aluminum strip, depending on the different operating conditions, the aluminum strip also needs to be coated with a coating machine to improve its corrosion resistance.

[0003] A utility model patent with publication number CN222099166U and publication date of December 3, 2024, discloses an aluminum strip winding tensioning device, including a bracket, a support seat mounted on the bracket, and a main tensioning mechanism mounted on the support seat. It also includes an auxiliary tensioning mechanism mounted on the support seat downstream of the main tensioning mechanism. The support seat includes two opposing sidewalls and mounting grooves formed in the sidewalls. The main tensioning mechanism includes a slide rail mounted outside the mounting groove, a mounting plate slidably mounted on the slide rail, a first tensioning roller assembly mounted between the mounting plates, and a tensioning component assembly connected to the mounting plate. The auxiliary tensioning mechanism includes an adjusting component mounted on the support seat and a second tensioning roller assembly connected to the adjusting component. This auxiliary tensioning mechanism can be used as a backup when maintaining or replacing the main tensioning mechanism, significantly reducing costs and making replacement more convenient compared to mechanisms such as adjusting motors.

[0004] However, the above-mentioned patent also has the following problems in its implementation: The length of the tensioning rollers in the above-mentioned patent is fixed. Due to the different application scenarios required during the aluminum strip cutting process, it is cut into different widths. The aluminum strip needs to be tensioned to a certain extent before entering the painting machine. Therefore, tensioning rollers of different lengths need to be configured. If the technical solution in the above-mentioned patent is used, the previous tensioning rollers need to be removed from the frame and then the new tensioning rollers need to be installed manually. This replacement method is very troublesome, and it is labor-intensive for the workers, resulting in low replacement efficiency.

[0005] Therefore, there is an urgent need for a three-way rotary quick-change mechanism to facilitate the replacement of tension rollers, improve replacement efficiency, and reduce labor intensity. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a rotary three-way quick-change roller mechanism to solve the problems of low replacement efficiency and inconvenience in existing tension roller replacement methods.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A rotary three-way quick wheel changing mechanism includes a frame, on which a rotating shaft is rotatably mounted, and at both ends of the rotating shaft are respectively provided conversion devices. Multiple tension rollers of different specifications are rotatably mounted on a virtual circle between the conversion devices.

[0009] One end of the rotating shaft is provided with a dial, the frame is provided with a braking device for braking the dial, and one end of the rotating shaft is also provided with a driving device.

[0010] Furthermore, the conversion device includes two conversion discs with isosceles triangular structures, and a first bearing seat is installed on each of the three sides of the conversion disc. The tension roller is mounted on the conversion disc through the first bearing seat.

[0011] Furthermore, the frame is provided with second bearing seats at both ends of the rotating shaft.

[0012] Furthermore, the dial is provided with a socket.

[0013] Furthermore, the braking device includes a pin and a brake clamp, the brake clamp being fixed on the frame, and the brake clamp having a through hole corresponding to the position of the pin.

[0014] Furthermore, the brake clamp is provided with a storage groove.

[0015] Furthermore, the included angle between the sockets is 120 degrees.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] (1) The three tension rollers of different specifications are integrated by using the conversion plate with an isosceles triangle structure. When the tension roller is replaced, the three tension rollers can be switched by simply rotating the conversion plate through the drive device. There is no need to disassemble the tension rollers, which facilitates the replacement of the tension rollers, improves the replacement efficiency and reduces the labor intensity.

[0022] The present invention will now be described clearly and completely with reference to the embodiments.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] See appendix Figure 1-3 The image shows a rotary three-way quick wheel changing mechanism, including a frame 1, on which a rotating shaft 2 is mounted laterally. A conversion disc 3 is provided at each end of the rotating shaft 2. The conversion disc 3 is specifically an isosceles triangle structure, and a first bearing seat 4 is installed on each side. Three tension rollers 5 of different lengths are rotatably mounted between the two conversion discs 3 through the first bearing seat 4. The three tension rollers 5 can be flexibly switched according to different production needs.

[0026] The frame 1 is provided with second bearing seats 6 at both ends of the rotating shaft 2, and a drive device 12 is provided at one end of the rotating shaft 2. In use, the drive device 12 drives the two conversion discs 3 to rotate, and the conversion discs 3 drive the three tension rollers to rotate. This realizes the switching between the three tension rollers 5 without the need for disassembly. The staff not only saves effort when changing them, but also has high efficiency.

[0027] Furthermore, a dial 7 is installed at one end of the rotating shaft 2, and a socket 8 is provided on the circumference of the dial 7. The included angle between the sockets 8 is 120 degrees. At the same time, a braking device is also provided on the frame 1. The braking device includes a brake clip 9 fixedly installed on the frame 1. The brake clip 9 has a through hole, and a pin 10 is provided in the through hole. When the three tension rollers 5 are replaced, the pin 10 is simply pulled out from the socket 8, and then the conversion disk 3 is rotated by the drive device 12.

[0028] Furthermore, in order to prevent the pin 10 from falling out of the socket 8, a storage groove 11 is provided on the brake clip 9. After replacement, the pin 10 is inserted into the socket 8 and placed in the storage groove 11.

[0029] See appendix for usage. Figure 3 As shown, first rotate the pin 10 counterclockwise by 180 degrees, then pull it out of the socket 8. Next, use the drive device 12 to drive the two conversion discs 3 to rotate. During the rotation, when the tension roller 5 that needs to be replaced reaches the usage position, insert the pin 10 into the corresponding socket 8 and place it in the storage slot 11.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
