[0023] The advantages of this invention are as follows:

[0024] In this invention, the driven shaft and the drive shaft work together, with the drive shaft driving the driven shaft and the drum on the driven shaft to rotate. This enables the invention to perform winding operations. The driven shaft and the drive shaft can share the weight of the rolled material and the driving force applied by the drive device, thereby reducing the pressure on each of the driven shaft and the drive shaft, making them less prone to damage. Simultaneously, the drive shaft braking assembly and the driven shaft braking assembly apply deceleration forces to the driven shaft and the drive shaft respectively, allowing the invention to stop the winding process in a timely manner to meet the needs of the rolled material. Furthermore, the deceleration forces applied to the driven shaft and the drive shaft by the driven shaft braking assembly and the drive shaft braking assembly reduce their rotational speed, alleviating the inertial forces exerted on the driven shaft, drive shaft, and drive device during drum rotation. This results in less inertial force on the driven shaft, drive shaft, and drive device when the invention stops the winding process, making them less prone to damage. This improves the working efficiency of the invention, while also reducing its durability and lowering its usage costs.

[0025] In this invention, the diameter of the driving wheel is larger than the diameter of the driving shaft, and the main drive wheel cooperates with the driven shaft to transmit rotational force; thus, the driving shaft improves the power transmission efficiency through the setting of the driving wheel; at the same time, the setting of the driving wheel makes it unnecessary for the driving shaft and the driven shaft to be tightly fitted at all points when transmitting rotational power, providing sufficient space for the assembly of the driving shaft braking assembly and the driven shaft braking assembly.

[0026] In this invention, a secondary drive wheel is provided on the driven shaft. The transmission between the driving shaft and the driven shaft is realized through the cooperation of the secondary drive wheel and the main drive wheel, and the secondary drive wheel and the main drive wheel bear most of the transmission pressure between the driving shaft and the driven shaft, making the driving shaft and the driven shaft less prone to damage. The secondary drive wheel and the main drive wheel are detachably assembled on the driving shaft and the driven shaft, and the front limit ring and the rear limit ring are detachably installed on the driving shaft and the driven shaft, which facilitates the replacement of the secondary drive wheel and the main drive wheel after damage; or the transmission efficiency between the driving shaft and the driven shaft can be improved by replacing the secondary drive wheel and the main drive wheel with different diameters.

[0027] In this invention, the mating areas of the drive shaft and the driven shaft are located within the mating space to prevent external objects from affecting the transmission between the drive shaft and the driven shaft; the drive shaft braking assembly and the driven shaft braking assembly are located outside the mating space and mate with the drive shaft and the driven shaft, thereby making the drive shaft braking assembly and the driven shaft braking assembly easier for operators to observe and operate.

[0028] In this invention, the other end of the drive shaft is rotatably connected to the housing, and the driven shaft is rotatably connected to the housing, so that the drive shaft and the driven shaft can rotate on their own while also being connected and cooperated with the drum, the drive device and the braking device.

[0029] In this invention, the drive device includes a drive motor and a reducer; by setting the reducer, the output torque is increased, thereby improving the power transmission efficiency between the drive shaft and the driven shaft.

[0030] In this invention, the rotational connection between the drive shaft and the driven shaft and the housing is achieved by setting up a first bearing and a second bearing.

[0031] In this invention, a first front mounting hole and a second front mounting hole are provided on the front side plate, and a first rear mounting hole and a second rear mounting hole are provided on the rear side plate. A first bearing is disposed in the first front mounting hole and the first rear mounting hole, and a second bearing is disposed in the second front mounting hole and the second rear mounting hole. This avoids interference between the drive shaft and the driven shaft and the housing, thus preventing the rotation of the drive shaft and the driven shaft from being resisted.

[0032] In this invention, both the front and rear side plates include an upper mounting plate and a lower mounting plate. When assembling the first and second bearings, the first and second bearings can be placed into the mounting opening of the lower mounting plate first, and then the front side plate can be assembled onto the rear side plate, thereby facilitating the assembly of the first and second bearings.

[0033] In this invention, when it is necessary to stop the winding process, the drive shaft can be decelerated by the left and right clamping arms of the disc brake unit driving the left and right brake pads to clamp the brake disc; or the driven shaft can be decelerated by the hydraulic rod entering the connecting space and abutting against the driven shaft. Thus, when the winding process is stopped, the driven shaft, drive shaft and drive device are subjected to less inertial force and are less likely to be damaged.

[0034] In this invention, the support plate is detachably mounted on the mounting base, allowing the inner diameter of the roll material to be changed by replacing the support plate; the mounting base is detachably mounted on the driven shaft, allowing the invention to be installed in the order of first mounting the support plate on the mounting base and then mounting the mounting base on the driven shaft, minimizing the difficulty of assembling the support plate due to its small size, and thus facilitating assembly by the operator; the setting of the fixing part and the second area makes the installation of the mounting base more secure.

[0035] In this invention, the assembly block allows the assembly base to be more stably assembled in the assembly slot.

[0036] In this invention, the fixing plate is inclined, with the end of the fixing plate facing the assembly opening being the high point and the end of the fixing plate away from the assembly opening being the low point; thus facilitating the assembly of the support plate onto the assembly seat installed inside the assembly slot.

[0037] In this invention, the position of the support plate is restricted by the setting of the anti-reverse block, making its assembly more secure and stable.

[0038] In this invention, an auxiliary winding device is used to apply an auxiliary force to the material being wound, so that each layer of the roll can be evenly bonded. Attached Figure Description

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0054] like Figures 1-12 As shown, a dual-speed variable-speed winding machine includes a drive shaft 1, a driven shaft 2, a drum 3, a drive device 4, and a braking device 5. The drum 3 is mounted on the driven shaft 2. The drive device 4 is connected to the drive shaft 1 and drives the drive shaft 1 and the driven shaft 2, which cooperates with the drive shaft 1, to rotate. The braking device 5 includes a drive shaft braking assembly 51 that cooperates with the drive shaft 1 and a driven shaft braking assembly 52 that cooperates with the driven shaft 2. The drive shaft braking assembly 51 and the driven shaft braking assembly 52 apply a force to the drive shaft 1 and the driven shaft 2 to reduce their rotational speed. In this invention, through the cooperation between the driven shaft 2 and the drive shaft 1, the drive shaft 1 drives the driven shaft 2 and the drum 3 on the driven shaft 2 to rotate. This enables the invention to perform winding operations. The driven shaft 2 and the drive shaft 1 can share the weight of the rolled material and the driving force applied by the drive device 4, thereby enabling the driven shaft 3 to rotate. The reduced pressure on shaft 2 and drive shaft 1 makes them less susceptible to damage. Simultaneously, the drive shaft braking assembly 51 and driven shaft braking assembly 52 apply deceleration forces to both shafts, enabling the invention to stop the winding process promptly to meet material requirements. Furthermore, the deceleration forces applied by the driven shaft braking assembly 52 and drive shaft braking assembly 51 reduce their rotational speed, mitigating the inertial forces exerted on shafts 2, drive shaft 1, and drive device 4 during drum 3 rotation. This results in less inertial force on shafts 2, drive shaft 1, and drive device 4 when the winding process stops, reducing their susceptibility to damage. This improves the invention's efficiency and reduces its cost.

[0055] In this embodiment, a main drive wheel 11 is provided on the drive shaft 1. The diameter of the drive wheel is larger than the diameter of the drive shaft 1. The main drive wheel 11 cooperates with the driven shaft 2 to transmit rotational force. This improves the power transmission efficiency of the drive shaft 1 through the setting of the drive wheel. At the same time, the setting of the drive wheel eliminates the need for tight contact at all points when transmitting rotational power between the drive shaft 1 and the driven shaft 2, providing sufficient space for the assembly of the drive shaft braking assembly 51 and the driven shaft braking assembly 52.

[0056] In this embodiment, a secondary drive wheel 21 is provided on the driven shaft 2. The diameter of the secondary drive wheel 21 is larger than the diameter of the driven shaft 2. The secondary drive wheel 21 cooperates with the main drive wheel 11 to transmit rotational force. The secondary drive wheel 21 and the main drive wheel 11 are detachably mounted on the driving shaft 1 and the driven shaft 2. A front limiting ring 12 and a rear limiting ring 13 are provided on both the driving shaft 1 and the driven shaft 2. The secondary drive wheel 21 and the main drive wheel 11 are both located between the front limiting ring 12 and the rear limiting ring 13. The front limiting ring 12 and the rear limiting ring 13 are detachably mounted on the driving shaft 1 and the driven shaft 2. The secondary drive wheel 21 and the main drive wheel... The cooperation of 11 enables the transmission between the drive shaft 1 and the driven shaft 2, and allows the auxiliary drive wheel 21 and the main drive wheel 11 to bear most of the transmission pressure between the drive shaft 1 and the driven shaft 2; making the drive shaft 1 and the driven shaft 2 less prone to damage; the auxiliary drive wheel 21 and the main drive wheel 11 are detachably mounted on the drive shaft 1 and the driven shaft 2, and the front limit ring 12 and the rear limit ring 13 are detachably mounted on the drive shaft 1 and the driven shaft 2, which facilitates the replacement of the auxiliary drive wheel 21 and the main drive wheel 11 after damage; or the transmission efficiency between the drive shaft 1 and the driven shaft 2 can be improved by replacing the auxiliary drive wheel 21 and the main drive wheel 11 with auxiliary drive wheels of different diameters.

The fact that the drive shaft braking assembly 51 and the driven shaft braking assembly 52 are located outside the mating space 61 and mate with the drive shaft 1 and the driven shaft 2 makes it easier for operators to observe and operate the drive shaft braking assembly 51 and the driven shaft braking assembly 52.

[0060] In this embodiment, the drive device 4 includes a drive motor 41 and a reducer 42. The reducer 42 includes an input end 421 and an output end 422. The motor shaft of the drive motor 41 is connected to the input end 421, and the end of the drive shaft 1 located outside the mating space 61 is connected to the output end 422.
