[0026] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail an automatic unhooking device applicable to pulp of the present utility model with reference to the drawings.
[0027] Such as Figure 1 、Figure 3 and Figure 4 As shown in Figure 4 and , an automatic hook - detaching device for pulp of the present utility model includes a fixed frame 1 and four groups of hook mechanisms 2 arranged below the fixed frame 1. The hook mechanism 2 includes a connection component 21 arranged below the fixed frame 1. A hook - detaching component 22 for detaching the pulp - wrapped hanging rope is arranged inside the connection component 21. The connection component 21 includes a connecting rod 211 fixedly connected to the lower end of the fixed frame 1. A cavity 212 is arranged inside the connecting rod 211. An installation cavity 215 is arranged below the cavity 212. A sliding cavity 216 is arranged on one side of the installation cavity 215. Two sides of the inner wall of the sliding cavity 216 are fixedly connected with limiting rods 217. A rotating cavity 218 is arranged on the other side of the installation cavity 215. Two sides of the inner wall of the rotating cavity 218 are provided with rotating grooves 219.
[0028] As Figure 2 、 Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , the connection component 21 further includes a telescopic electric cylinder 213 fixedly connected to the upper part inside the cavity 212. The output end of the telescopic electric cylinder 213 is fixedly connected with a locking block 214.
[0029] The telescopic electric cylinder 213, the installation cavity 215, the sliding cavity 216 and the rotating cavity 218 are connected through - holes.
[0030] The hook - detaching component 22 includes a motor 221 fixedly connected to one side of the connecting rod 211. The output end of the motor 221 penetrates through the connecting rod 211 and is fixedly connected with a driving gear 222.
[0031] The locking block 214 is located directly above the driving gear 222. The locking block 214 presses against the driving gear 222 through the cavity 212 to prevent the driving gear 222 from rotating on its own.
[0032] The hook - detaching component 22 further includes a double - sided rack plate 223 slidably connected inside the sliding cavity 216. Two sides of the double - sided rack plate 223 are provided with sliding grooves 224. A driven gear 225 is arranged inside the rotating cavity 218. A connecting shaft 226 is fixedly connected inside the driven gear 225. The connecting shaft 226 rotates inside the rotating groove 219. A groove 227 is arranged on the driven gear 225.
[0033] The driving gear 222 is meshed and connected with the double - sided rack plate 223. The driven gear 225 is meshed and connected with the double - sided rack plate 223.
[0034] The motor 221 drives the driving gear 222 to rotate. The driving gear 222 meshes with the double - sided rack plate 223 to move, so that the double - sided rack plate 223 drives the driven gear 225 to rotate. When the driven gear 225 rotates, the groove 227 is exposed from the rotating cavity 218. At this time, the opening direction of the groove 227 is upward, and the pulp - wrapped rope is hung into the groove 227.
[0035] Four lifting rings 12 are fixedly connected to the upper end of the fixing frame 1 , and four weight-reducing grooves 13 are provided on the fixing frame 1 .
[0036] To sum up: when it is necessary to hoist the pulp package, the motor 221 drives the double-sided rack plate 223 to move through the driving gear 222, and the double-sided rack plate 223 engages the driven gear 225 to rotate, so that the groove 227 is exposed from the rotating chamber 218, and the pulp package rope is hung in the groove 227. The output end of the telescopic electric cylinder 213 drives the lock block 214 to output against the driving gear 222 to prevent the driving gear 222 from rotating, causing the double-sided rack plate 223 to drive the driven gear 225 to rotate. After the hoisting is completed, the motor 221 continues to drive the driving gear 222 to rotate, and the driving gear 222 drives the driven gear 225 to rotate through the double-sided rack plate 223, so that the opening direction of the groove 227 faces downward, causing the pulp package rope to fall from the groove 227. There is no need to manually remove the pulp package rope, saving hoisting time.
[0037] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
