Description

Technical Field

[0002] With the rapid development of aerospace, automotive, and new energy fields, composite materials are being used more and more widely due to their advantages such as lightweight and high strength. Consequently, the scale of extrusion composite production lines is continuously expanding, leading to increasingly higher demands for production continuity and efficiency. In extrusion composite production, unwinding and feeding is a core upstream step, requiring a continuous supply of substrate material for subsequent processes such as lamination and molding. However, as production line capacity increases, traditional feeding methods are gradually becoming insufficient to keep up with the pace, necessitating the development of stable feeding equipment capable of handling high-capacity production.

[0003] Existing devices primarily use transfer carts to move multiple sets of material rolls to the loading rack. Existing technologies are largely similar to methods and systems for transferring rolled materials. For example, CN114933131B includes the following steps: receiving a transfer command and controlling the material roll cart to move to the designated machine position; the material roll cart continues to move below the rolled material; the lifting mechanism on the material roll cart is activated; the lifting mechanism raises the support frame, which carries the rolled material; the material roll cart, carrying the rolled material, leaves the designated machine position; the material roll cart, through the lifting mechanism and the support frame, places the rolled material on the loading rack; and a forklift transports the loading rack containing the rolled material to a designated area. This invention, a method and system for transferring rolled materials, can solve the technical problem of existing factories lacking supporting unloading and transfer methods and automated equipment for unloading and transferring rolled materials from production equipment. It can greatly improve production efficiency and enhance the automation level of both new and old factories. However, there are still areas for optimization in this device.

[0029] A drive motor 205 is fixedly mounted on the front center of the sliding frame 204, and a drive shaft 206 is fixedly connected to the rear center of the drive motor 205.

A first bevel gear 207 is fixedly connected to the outer wall of the drive shaft 206 inside the sliding frame 204. Through this design, the drive motor 205 can drive the drive shaft 206 and the first bevel gear 207 to slide synchronously, so that the first bevel gear 207 can mesh with the second bevel gear 301 or the third bevel gear 401, which facilitates the drive motor 205 to serve as the power source for driving the lifting and connecting mechanism 3 and the shifting and connecting mechanism 4 in sequence.

[0030] The material lifting and connecting mechanism 3 includes a second bevel gear 301. A symmetrical screw 302 is fixedly connected to the middle right side of the second bevel gear 301. The right end of the symmetrical screw 302 passes through the middle partition of the fixed frame 103 and is movably connected to the right side wall of the fixed frame 103. Material lifting sleeves 303 are threaded on both sides of the outer wall of the symmetrical screw 302. Through this design, the second bevel gear 301 drives the symmetrical screw 302 to rotate in a limited position, so that the symmetrical screw 302 drives the material lifting sleeves 303 to slide symmetrically.

[0031] A lifting rod 304 is movably connected to the upper part of the outer wall of the lifting screw sleeve 303. The top end of the lifting rod 304 is movably connected to both sides of the bottom of the lifting platform 104. The top surface of the lifting platform 104 is a concave curved surface. Telescopic rods are fixedly installed at the four corners of the bottom of the lifting platform 104, and the bottom ends of the telescopic rods are fixedly installed on the top of the fixed frame 103. Through this design, the lifting screw sleeve 303 drives the bottom end of the lifting rod 304 to slide synchronously, so that the top end of the lifting rod 304 drives the lifting platform 104 to slide up and down, which facilitates the lifting of the material roll from the slide 107 to the material rack 101.

[0032] The shifting and connecting mechanism 4 includes a third bevel gear 401. A linkage shaft 402 is fixedly connected to the middle left side of the third bevel gear 401. The left end of the linkage shaft 402 passes through the left side wall of the fixed frame 103 and is movably connected to the left side of the inner wall of the transmission box 105. A linkage pulley 403 is fixedly connected to the outer wall of the linkage shaft 402 inside the transmission box 105. Through this design, the third bevel gear 401 drives the linkage shaft 402 and the linkage pulley 403 to rotate synchronously.

[0033] A pair of drive belts 404 are tightly attached to the outer wall of the linkage pulley 403. A driven pulley 405 is tightly attached to the other side of the inner wall of the drive belts 404. A drive screw 406 is fixedly connected to the inner wall of the driven pulley 405, and the left end of the drive screw 406 is movably connected to the left side of the inner wall of the transmission box 105. This design enables the linkage pulley 403 to drive the pair of driven pulleys 405 to rotate synchronously via the drive belts 404, thus causing the driven pulleys 405 to drive the drive screw 406 to rotate in a limited position.

[0034] The right end of the drive screw 406 passes through the left side wall of the fixed frame 103 and is fitted with a pusher screw 408. The right end of the pusher screw 408 is fixedly connected to the right side of the inner wall of the slide 107, and the top surface of the slide 107 is V-shaped. This design enables the drive screw 406 to drive the pusher screw 408 and the slide 107 to slide left and right, allowing the slide 107 to move the material roll above the lifting platform 104. A protective sleeve 407 is fitted onto the left side of the outer wall of the pusher screw cylinder 408. The left end of the protective sleeve 407 is fixedly mounted on the right side of the left side wall of the fixing frame 103. A limit strip is fixedly connected to the upper part of the inner wall of the protective sleeve 407. A sliding groove corresponding to the limit strip is formed on the upper part of the outer wall of the pusher screw cylinder 408. Through this design, the pusher screw cylinder 408 is limited and slides within the inner wall of the protective sleeve 407, effectively preventing the pusher screw cylinder 408 from rotating.

[0035] Working principle: When power docking is required, the servo motor 201 is first started through the control panel 102. The servo motor 201 drives the movable screw 202 to rotate in a limited position. The movable screw 202 drives the push sleeve 203 to slide left and right. The push sleeve 203 drives the sliding frame 204 to slide in a limited position. The sliding frame 204 drives the drive motor 205, drive shaft 206 and first bevel gear 207 to slide synchronously, so that the first bevel gear 207 can mesh with the second bevel gear 301 or the third bevel gear 401. This allows the drive motor 205 to serve as the power source for driving the lifting docking mechanism 3 and the shifting docking mechanism 4 in sequence, thus realizing the power docking operation.

[0036] When it is necessary to move and connect the material roll, the drive motor 205 is first started via the control panel 102. The drive motor 205 drives the drive shaft 206 to rotate to a limit position, and the drive shaft 206 drives the first bevel gear 207 to slide synchronously. The first bevel gear 207 meshes and drives the third bevel gear 401 to rotate. The third bevel gear 401 drives the linkage shaft 402 to rotate to a limit position, and the linkage shaft 402 drives the linkage pulley 403 to rotate synchronously. The linkage pulley 403 drives a pair of driven pulleys 405 to rotate synchronously via the transmission belt 404. The driven pulleys 405 drive the transmission screw 406 to rotate to a limit position, and the transmission screw 406 drives the pusher barrel 408 and the slide 107 to slide left and right. The slide 107 can move the material roll to above the lifting platform 104. This realizes the material roll moving and connecting operation.

[0037] When it is necessary to move and connect the material roll, the drive motor 205 is first started via the control panel 102. The drive motor 205 drives the drive shaft 206 to rotate in a limited position, and the drive shaft 206 drives the first bevel gear 207 to slide synchronously. The first bevel gear 207 meshes and drives the second bevel gear 301, which drives the symmetrical screw 302 to rotate in a limited position. The symmetrical screw 302 drives the lifting screw sleeve 303 to slide symmetrically, and the lifting screw sleeve 303 drives the bottom end of the lifting rod 304 to slide synchronously. The top end of the lifting rod 304 drives the lifting platform 104 to slide up and down, and the lifting platform 104 lifts the material roll from the slide 107 to the loading shaft of the material rack 101, thus realizing the moving and connecting operation of the material roll.

[0038] When it is necessary to load and connect the material rolls, firstly, the electromagnet 115 is activated via the control panel 102. The electromagnet 115 attracts the iron block 114, which drives the pin 111 and the roll plug 112 to slide outward and compress the spring 113. This allows the material roll to be lifted and moved to the loading shaft of the material rack 101. Then, the electromagnet 115 is deactivated via the control panel 102. The compressed spring 113 drives the pin 111 and the roll plug 112 to automatically reset, so that the roll plug 112 is inserted into the central shaft of the material roll, thus completing the loading and connecting operation. The operation is now complete.
