Detailed Implementation

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] like Figure 1-5 As shown, rolling is a metal processing technology in which metal billets are passed through the gap (of various shapes) of a pair of rotating rolls. Due to the compression of the rolls, the cross-section of the material decreases and the length increases. During the rolling process, the two sides of the strip in the width direction are uneven. In order to form products with uniform specifications, the strip needs to be trimmed. This application discloses a powder rolled strip winding machine, which provides a trimming mechanism to cut the two sides of the strip. The trimming mechanism 100 includes a frame 140, on which a pair of symmetrically arranged first trimming devices 110 and second trimming devices 150 are provided. The first trimming device... Both the 110 and the second edge-cutting device 150 include a bracket 115. Each bracket 115 is provided with a first edge-cutting wheel shaft and a second edge-cutting wheel shaft. A first edge-cutting wheel 112 is provided at one end of the first edge-cutting wheel shaft, and a transmission gear 116 is fixed at the other end of the first edge-cutting wheel shaft. A second edge-cutting wheel 111 is provided at one end of the second edge-cutting wheel shaft, and a transmission gear 116 is fixed at the other end of the second edge-cutting wheel shaft. The second edge-cutting wheel shaft is meshed with the transmission gear 116 of the second edge-cutting wheel shaft. The edges of the first edge-cutting wheel 112 and the edges of the second edge-cutting wheel 111 are arranged alternately to form a shearing structure.

[0022] A drive shaft 114 is provided on the frame 140. The drive shaft 114 is connected to the first edge-aligning wheel shaft of the first edge-cutting device 110. At the same time, the drive shaft 114 is also connected to the first edge-aligning wheel shaft of the second edge-cutting device 150. A first drive device 160 is provided on the frame 140 at one end of the drive shaft 114. The first drive device 160 includes a first motor 162 and a first reducer 161. One end of the drive shaft 114 is connected to the output shaft of the first reducer 161 through a flexible coupling. The input shaft of the first reducer 161 is connected to the main shaft of the first motor 162.

[0023] Specifically, the drive shaft 114 is provided with two splines. The first flush-edge wheel shaft is a hollow sleeve structure. The hollow sleeve has a spline groove that connects to one spline of the drive shaft 114. The other first flush-edge wheel shaft is also a hollow sleeve structure. The hollow sleeve also has a spline groove that connects to the other spline of the drive shaft 114.

[0024] In another embodiment, the drive shaft 114 is provided with two sliding keys. The first flush-edge wheel shaft is a hollow sleeve structure. The hollow sleeve has a keyway that connects to one sliding key of the drive shaft 114. The other first flush-edge wheel shaft is also a hollow sleeve structure. The hollow sleeve also has a keyway that connects to the other sliding key of the drive shaft 114.

[0025] To allow the spacing between the first trimming device 110 and the second trimming device 150 to be adjusted to accommodate trimmings of different widths, the first trimming device 110 is mounted on the first slide table 119, and the second trimming device 150 is mounted on the second slide table 117. A lead screw and nut mechanism is provided on the frame 140. The lead screw 118 of the lead screw and nut mechanism is connected to the nut of the bracket 115 of the first trimming device 110 or the second trimming device 150. One end of the lead screw of the lead screw and nut mechanism is connected to a second drive device, which is a second motor, to drive the first trimming device 110 and the second trimming device 150 to move closer or further apart. With this structure, the rotation of the second drive device drives the first trimming device 110 and the second trimming device 150 to slide on the first slide table 119 and the second slide table 117 to adjust the trimming width between the first trimming device 110 and the second trimming device 150, thus adapting to strips of different widths.

[0026] The drive shaft 114 is equipped with two sliding keys, and the two first edge-aligning wheel shafts are slidably connected to one of the sliding keys, allowing them to slide along the keys. The drive shaft 114 is connected to a first drive device to drive the edge-aligning wheels on the first edge-aligning device 110 and the second edge-aligning device 150 to rotate. With this structure, when adjusting the edge-aligning width, the two first edge-aligning wheel shafts can slide on the drive shaft 114, and the drive shaft 114 can still transmit torque to the first edge-aligning wheel 112 and the second edge-aligning wheel 111. Through the drive shaft 114 structure, it is ensured that the first edge-aligning wheel 112 and the second edge-aligning wheel 111 rotate synchronously, avoiding strip vibration and improving edge-aligning quality.

[0027] In a preferred embodiment, the lead screw and nut mechanism is a ball screw and nut mechanism. This structure can reduce friction during the width adjustment process, making the adjustment smoother.

[0028] In a preferred embodiment, the first edge-cutting device 110 is further provided with a vertically arranged guide roller 113 on its support 115, and the second edge-cutting device 150 is also provided with a vertically arranged guide roller 113 on its support 115, so that the strip after edge cutting is guided by the two guide rollers 113.

[0029] A winding mechanism 200 is provided on one side of the frame 140. The winding mechanism 200 includes a winding bracket 207, a winding shaft 206, a stainless steel bushing 204 on the winding shaft 206, and guard plates 205 on both sides of the stainless steel bushing 204 to form winding grooves. A pulley 208 is provided at one end of the winding shaft. A winding motor is provided on the winding bracket 207, and a pulley 208 is also provided on the main shaft of the winding motor. The two pulleys 208 are connected by a transmission belt.

[0030] In a preferred embodiment, the frame 140 is further provided with an arc-shaped transition plate 130. One end of the transition plate 130 is connected to the edge-cutting mechanism 100, and the other end is connected to the winding mechanism 200. Two sensors 120 are provided above the arc bottom of the transition plate 130. The strip will sag under its own weight. When the strip triggers the sensor 120 at the lower position, the winding mechanism 200 can automatically increase the winding speed. When the strip triggers the sensor 120 at the upper position, the winding mechanism 200 can automatically decrease the winding speed, so that the winding speed of the winding mechanism 200 matches the production process.

[0031] In a preferred embodiment, the winding bracket 207 is provided with a vertically positioned stroke cylinder 201, which is suspended above the winding groove. The piston rod 202 of the stroke cylinder 201 faces downward toward the winding groove, and a horizontally positioned main shaft is installed at the end of the piston rod 202. Rubber wheels 203 are rotatably connected to both ends of the main shaft. The stroke cylinder 201 drives the rubber wheels 203 to press against the strip material, thereby preventing the strip material from shaking and improving the winding quality.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
