[0024] Working principle of this embodiment: In order to facilitate the use of the cold rolling feeding equipment, firstly, the rolled aluminum strip to be cold rolled is placed on the top of the limit plate 207 through a position away from the extrusion assembly 3, so that one end of the aluminum strip winding roller is located on the upper part of the extrusion plate 303, and the opening is facing the top of the extrusion plate 303, wherein, as Figure 3 As shown, the cross section of the limit plate 207 is in a shape with high sides and a concave center, the purpose of which is to facilitate the limitation of the aluminum strip to prevent it from moving during the transportation process. After the aluminum strip is placed, when the center position of the aluminum strip winding roller is lower than the center position of the positioning block 218, the air pump 213 is started to transport gas to the inside of the output pipe 214, so that the gas flows to the inside of the multiple connecting pipes 212, thereby entering the inside of the multiple hollow columns 208, thereby increasing the air pressure inside the multiple hollow columns 208, and then under the action of the high pressure, the multiple pistons 210 are driven to move upward, and then the multiple lifting rods 211 are driven to move upward, so that the limit plate 207 moves upward, thereby driving the aluminum strip to move upward, until the center position of the aluminum strip winding roller and the center of the positioning block 218 are on the same straight line. When the center position of the aluminum strip winding roller is When the position is higher than the center of the positioning block 218, the air pump 213 is started again to extract gas into the output pipe 214, thereby driving the aluminum strip winding roller to move downward. When the center position of the aluminum strip winding roller is on the same straight line as the center circle of the positioning block 218, the servo motor 201 is started to drive the rotating shaft 202 to rotate, thereby driving the driving gear 203 to rotate, thereby driving the two gear rows 206 to move along the direction of the slide rail 204 respectively, thereby driving the two connecting rods 215 to move toward each other, thereby driving the two groups of positioning blocks 218 to move toward each other until the two groups of positioning blocks 218 clamp the aluminum strip. When the aluminum strip is placed on the limit plate 207, the extrusion plate 303 is squeezed, and then the multiple first springs 302 are squeezed, so that the outer surface of the extrusion plate 303 is tightly attached to the outer surface of the aluminum strip winding roller. Figure 3 As shown, the limiting plate 207 limits the two connecting rods 215, making them move more smoothly. After the aluminum strip is positioned, the forward and reverse motors 103 are started to drive the screw rod 104 to rotate, thereby driving the load-bearing plate 105 to move forward. Figure 2As shown, the connection between the load-bearing plate 105 and the slideway 101 plays a role in limiting the load-bearing plate 105. When the aluminum strip winding roller moves to the outside of the positioning rod of the external processing equipment, the cylinder 106 is started to extend, driving the two telescopic rods 107 to extend, driving the two groups of positioning blocks 218 to move upward, until the two groups of positioning blocks 218 are respectively moved to the same straight line as the positioning rod of the external processing equipment, and then continue to start the forward and reverse motors 103 to drive the two groups of positioning blocks 218 to move to the positioning rod of the external processing equipment. When the positioning blocks 218 are respectively sleeved on the positioning rods, that is, the aluminum strip is also sleeved on the positioning rods, and then the oil cylinder 408 is started to extend, driving the positioning tube 409 to move forward, and then driving the two limit blocks 410 to move forward, until the two limit blocks 410 are moved to the inside of the card slot 406, and the card slot 406 plays a role in limiting the two limit blocks 410. When one end of the positioning tube 409 is inserted into the inside of the aluminum strip winding roller, the stepper motor 412 is started to drive the installation rod 413 to rotate, and then drive the rotating gear 414 to rotate, wherein, as Fig.12 As shown, by inserting one end of the mounting rod 413 into the interior of the reinforcing plate 401, the purpose is to ensure the stability of the mounting rod 413. At the same time, the rotation of the rotating gear 414 drives the gear ring 405 to rotate, and the gear ring 405 drives the two limit blocks 410 to rotate, thereby driving the positioning tube 409 to rotate, wherein the outer diameter of the positioning tube 409 matches the inner diameter of the internal hollow circle position of the aluminum strip, so that the aluminum strip winding roller rotates counterclockwise with the rotation of the positioning tube 409. When one end of the aluminum strip winding roller rotates to the position in contact with the extrusion plate 303, the aluminum strip winding roller is squeezed at one end and released from the aluminum strip winding roller and stays on the top of the extrusion plate 303, that is, the automatic release of one end of the aluminum strip winding roller is completed, and there is no need for the staff to manually pull out one end of the aluminum strip, and then one end of the aluminum strip winding roller can be placed in the corresponding processing equipment, which solves the existing technical problems. During the operation, the staff may easily cause harm to their personal safety when pulling the aluminum strip out of the winding device. Then, the cylinder 106 is started again to shorten it, driving the two groups of positioning blocks 218 to move downward. When the inner walls of the two groups of positioning blocks 218 move to the position of the positioning rod, each two adjacent positioning blocks 218 are squeezed and rotated in opposite directions along the rotating rod 217, thereby causing the two groups of second springs 219 to be squeezed and shortened until the two groups of positioning blocks 218 are respectively moved to the outside of the positioning rod of the external processing equipment, and then the two groups of second springs 219 are extended under the action of their own elastic force, so that each two relative positioning blocks 218 are respectively reset under the elastic action of the second springs 219, thereby completing the automatic loading of the aluminum strip. The clamping and fixing of the two groups of positioning blocks 218 can effectively prevent the aluminum strip winding roller from loosening due to friction during the loading process.

[0025] Embodiment 2: According to Figure 1-12 As shown, a method for using a feeding device for processing cold-rolled aluminum strips includes placing an aluminum strip winding roller on the top of a limiting plate 207 so that the outer surface of the aluminum strip winding roller is tightly attached to the outer surface of an extrusion plate 303. After the aluminum strip winding roller is placed on the top of the limiting plate 207, the forward and reverse motors 103 are started to drive the lead screw 104 to rotate, thereby driving the aluminum strip winding roller to move toward the positioning rod of the processing equipment. When the aluminum strip winding roller moves to the outer surface of the positioning rod, the cylinder 106 is started to drive the aluminum strip winding roller to move upward, so that the aluminum strip winding roller is The center of the winding roller is in the same straight line as the center of the positioning block 218 and the center of the positioning rod. Then, the aluminum strip winding roller continues to be moved toward the positioning rod so that the aluminum strip winding roller is sleeved on the positioning rod of the processing equipment. The loading of the aluminum strip winding roller is completed. When the loading of the aluminum strip winding roller is completed, the cylinder 106 is started again to shorten it, driving the aluminum strip winding roller to move downward, thereby squeezing the two positioning blocks 218, and then causing the two groups of positioning blocks 218 to rotate in opposite directions respectively until the two positioning blocks 218 are moved out of the positioning rod of the processing equipment.

[0026] The working principle of this embodiment: when in use, during the process of processing and feeding the rolled aluminum strip, first start the cylinder 106 to shorten it, thereby driving the pressure plate 108 to move downward to the lowest position, wherein the two telescopic rods 107 support the pressure plate 108, and then place the aluminum strip on the top of the limit plate 207 through an external conveying device, so that the aluminum strip winding roller and the limit plate 207 are in a parallel position, and at the same time, the open end of the aluminum strip winding roller is located on the upper part of the extrusion plate 303, and the opening is opposite to the top of the extrusion plate 303, and then start the forward and reverse motors 103 to drive the aluminum strip to be rolled. The roller moves to one end of the positioning rod of the external processing equipment, and the cylinder 106 is started again to extend it, so that the center of the external positioning rod and the center of the positioning block 218 and the center position of the aluminum strip winding roller are at the same center. When the aluminum strip winding roller is completely mounted on the external positioning rod, the cylinder 106 is started again to shorten it, driving the two positioning blocks 218 to move downward, so that the two positioning blocks 218 rotate in the opposite direction along the rotating rod 217 respectively, and then the second spring 219 is squeezed and shortened, so that the two positioning blocks 218 are respectively moved out from the positioning rod, and the automatic loading of the aluminum strip winding roller is completed.

[0027] In the present invention, in order to facilitate the use of the cold rolling feeding equipment, the rolled aluminum strip to be cold rolled is first placed on the top of the limit plate 207 through a position away from the extrusion assembly 3, so that one end of the aluminum strip winding roller is located on the upper part of the extrusion plate 303, and the opening is directly opposite to the top of the extrusion plate 303. When the center of the aluminum strip winding roller is lower than the center of the center of the positioning block 218, the air pump 213 is started to transport gas to the inside of the output pipe 214, so that the gas flows to the inside of the multiple connecting pipes 212, and then enters the inside of the multiple hollow columns 208, so that the air pressure inside the multiple hollow columns 208 increases, and then under the action of the high pressure, the multiple pistons 210 are driven to move upward, and then the multiple lifting rods 211 are driven to move upward. Thereby, the limit plate 207 moves upward, thereby driving the aluminum strip to move upward, until the center position of the aluminum strip winding roller is in the same straight line with the center of the positioning block 218. When the center position of the aluminum strip winding roller is higher than the center of the positioning block 218, the air pump 213 is started again to extract gas into the inside of the output pipe 214, thereby driving the aluminum strip winding roller to move downward. When the center position of the aluminum strip winding roller is in the same straight line with the center circle of the positioning block 218, the servo motor 201 is started to drive the rotating shaft 202 to rotate, thereby driving the driving gear 203 to rotate, thereby driving the two gear rows 206 to move respectively along the direction of the slide rail 204, thereby driving the two connecting rods 215 to move toward each other, thereby driving the two sets of positioning blocks 218 to move toward each other. The first spring 302 is pressed against the first spring 303, and the second spring 303 is pressed against the first spring 304. When the aluminum strip is positioned, the forward and reverse motor 103 is started to drive the lead screw 104 to rotate, thereby driving the load-bearing plate 105 to move forward. When the aluminum strip winding roller moves to the outside of the positioning rod of the external processing equipment, the cylinder 106 is started to extend, driving the two telescopic rods 107 to extend, and driving the two positioning blocks 218 to move upward until the two positioning blocks 218 are respectively moved to the same straight line as the positioning rod of the external processing equipment, and then continue to start. The forward and reverse motors 103 are driven to drive the two groups of positioning blocks 218 to move to the positioning rods of the external processing equipment respectively. When the two groups of positioning blocks 218 are respectively sleeved on the positioning rods, that is, the aluminum strip is also sleeved on the positioning rods, and then the oil cylinder 408 is started to extend it, driving the positioning tube 409 to move forward, and then driving the two limit blocks 410 to move forward until the two limit blocks 410 are moved to the inside of the slot 406. When one end of the positioning tube 409 is inserted into the inside of the aluminum strip winding roller, the stepper motor 412 is started to drive the installation rod 413 to rotate, and then drive the rotating gear 414 to rotate. At the same time, the rotation of the rotating gear 414 drives the gear ring 405 to rotate, and the gear ring 405 drives the two limit blocks 410 to rotate, and then drives the positioning tube 409 to rotate.As a result, the aluminum strip winding roller rotates counterclockwise with the rotation of the positioning tube 409. When one end of the aluminum strip winding roller rotates to the position in contact with the extrusion plate 303, one end of the aluminum strip winding roller is squeezed and released from the aluminum strip winding roller, and stays on the top of the extrusion plate 303, that is, the release of one end of the aluminum strip winding roller is completed, and then the cylinder 106 is started again to shorten it, driving the two groups of positioning blocks 218 to move downward. When the inner walls of the two groups of positioning blocks 218 move to the position of the positioning rod, each adjacent two positioning blocks 218 are squeezed and rotated in opposite directions along the rotating rod 217, thereby causing the two groups of second springs 219 to be squeezed and shortened until the two groups of positioning blocks 218 are respectively moved to the outside of the positioning rod of the external processing equipment, and then the two groups of second springs 219 are extended under the action of their own elastic force, so that each two relative positioning blocks 218 are reset under the elastic action of the second springs 219, thereby completing the automatic feeding of the aluminum strip.
