The chain is wound around the driving sprocket and the driven sprocket to drive the driving sprocket to rotate through the power device, and the driving sprocket drives the chain transmission. During use, if the chain ages and relaxes, affecting the overall power effect of the equipment, since the position of the driving sprocket cannot be adjusted, the length of the chain is generally shortened by disassembling the chain, but this method is not convenient for tensioning the chain. With the development of science and technology, an active sprocket adjustment device has recently appeared in the industry. Although the active sprocket adjustment device can adjust the position of the active sprocket to facilitate the tensioning of the chain, the adjustment of the position of the active sprocket is relatively cumbersome, and thus cannot meet the high requirements of the industry.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0024] like Figure 1-5 As shown, a driving sprocket adjustment device includes a support seat 10, a power fixing seat 20, a driving sprocket 30, a power device 40 and a pushing device 50; a guide member 60 is provided on the support seat 10, and the power fixing seat 20 can be slidably mounted on the guide member 60 and can slide along the extension direction A of the guide member 60; the power device 40 is mounted on the power fixing seat 20; the driving sprocket 30 is connected to the power device 40, and the driving sprocket 30 is driven to rotate by the power device 40; the driving sprocket 30 is used for chain winding; the pushing device 50 is mounted on the support seat 10, and the pushing device 50 includes a resisting top portion 51 that can move along the extension direction of the guide member 60 and is used to resist the power fixing seat 20.
[0025] When in use, the power device 40 works to drive the driving sprocket 30 to rotate, so as to drive the chain transmission wound on the driving sprocket 30. The abutting top portion 51 of the pushing device 50 moves forward along the extension direction of the guide member 60, and can abut the power fixing seat 20 forward, so that the power device 40 together with the driving sprocket 30 slides forward along the extension direction of the guide member 60 along with the power fixing seat 20, so that the tightness of the chain can be adjusted to tighten the chain, and the abutting top portion 51 of the pushing device 50 moves backward along the extension direction of the guide member 60, and the driving sprocket 30 is slightly moved backward and maintained at a predetermined position under the joint action of the chain and the abutting top portion 51 of the pushing device 50, so that the tightness of the chain can be adjusted. Therefore, the utility model provides a driving sprocket adjustment device, which adopts the support seat 10, the power fixing seat 20, and the driving sprocket 30. The combination of the sprocket 30, the power device 40 and the pushing device 50 can make the power fixing seat 20 slide along the extension direction of the guide member 60 by the abutting top portion 51 of the pushing device 50, so that the power device 40 together with the driving sprocket 30 moves along with the power fixing seat 20 to adjust the position of the driving sprocket 30, so that the chain can be conveniently tensioned by adjusting the position of the driving sprocket 30 without disassembling or replacing the chain. Moreover, the position of the driving sprocket 30 can be adjusted by abutting the power fixing seat 20 with the abutting top portion 51 of the pushing device 50 to make the power fixing seat 20 move along the extension direction of the guide member 60, so that the adjustment of the position of the driving sprocket 30 is relatively simple and convenient, which can save adjustment time and improve adjustment efficiency.
[0026] The driving sprocket 30 adjustment device also includes a bearing 70; the central axis of the bearing 70 coincides with the rotation axis of the driving sprocket 30; the outer ring of the bearing 70 is fixed on the power fixing seat 20, and the driving sprocket 30 is connected to the inner ring of the bearing 70. By adopting the above-mentioned arrangement, the smoothness of the rotation of the driving sprocket 30 can be improved, so that the power transmitted to the driving sprocket 30 by the power device 40 is smoother, and the wear and consumption of the power device 40 is reduced.
[0027] The pushing device 50 includes a screw rod installed on the support seat 10 , and the abutting portion 51 is formed on one end of the screw rod close to the power fixing seat 20 .

However, using a screw rod for the pushing device 50 is the most preferred embodiment of the utility model, which can facilitate operation and reduce the manufacturing and installation costs.
[0029] The screw rod can be threadedly connected to the support seat 10. When in use, by rotating the screw rod in the forward direction, the screw rod screws forward, so that the top portion 51 moves forward along the extension direction of the guide member 60, and by rotating the screw rod in the reverse direction, the screw rod screws backward, so that the top portion 51 moves backward along the extension direction of the guide member 60.
[0030] Of course, in addition to this, the screw rod can be directly locked on the support seat 10 by a nut, or, on the basis of being threadedly connected to the support seat 10, the screw rod can be locked on the support seat 10 by a nut. When in use, the nut can be loosened, and then the screw rod can be pushed or screwed in along the extension direction of the guide member 60 to push the power fixing seat 20 along the extension direction of the guide member 60 through the abutment top 51. After the screw rod moves into place, the nut can be tightened to lock the screw rod, thereby improving the stability of the screw rod fixation and ensuring stable tension.
