[0045] During the specific implementation of this embodiment: first, the packaging bag waste to be processed will enter the L-shaped feeding barrel 3 from the feeding square bucket 27, and at this time, the driving bevel gear 24 will be controlled by the variable speed motor 23 to rotate, and then the transmission bevel gear 25 meshing with the driving bevel gear 24 will drive the active roller 19 to rotate, and with the cooperation of the driven roller 20, the conveying belt 21 will work to convey the packaging bag waste entering the L-shaped feeding barrel 3, and finally the packaging bag waste will leave the tail end of the conveying belt 21 and enter the crushing bin 2 at the bottom opening of the L-shaped feeding barrel 3 to complete the entire feeding process, and all the crushing blades 8 on the crushing shaft 7 will be controlled by the driving motor 6 to rotate at high speed to fully crush the incoming packaging bag waste;

[0046] Secondly, during the feeding stage, the frequency converter 26 can flexibly adjust the rotation speed of the variable speed motor 23, and then the feeding speed can be flexibly adjusted according to the material crushing speed in the crushing bin 2, thereby avoiding the situation where the material is seriously accumulated in the crushing bin 2 due to the feeding speed being too fast, and avoiding the situation where the material processing speed is affected by the feeding speed being too slow.

[0047] Example 2, reference Figure 1-6 , this embodiment is optimized on the basis of embodiment 1, specifically: a waste material processing device for packaging bags, further comprising an airflow auxiliary mechanism disposed on the crushing bin 2;

[0048] Specifically, the airflow auxiliary mechanism includes an air supply cover 9 fixedly connected to the outer wall of the rear side of the crushing bin 2, an air inlet hole opened on one side of the air supply cover 9, a support rod 10 fixedly connected to the side wall of the air supply cover 9, a transmission shaft 11 rotatably mounted on the support rod 10, a supply fan blade 12 fixedly connected to the transmission shaft 11 and located in the air inlet hole, a gear transmission assembly and an adjustable air supply assembly;

[0051] When the adjustable air supply component is in use: during the blowing process of the hair dryer 15, the output shaft of the motor 17 is controlled to drive the air guide plate 18 to rotate continuously, so that the air guide angle of the air guide plate 18 can be continuously adjusted, so that the air blowing angle can be flexibly adjusted, so that the cold air can be fully and evenly blown into the crushing bin 2;

[0052] In the specific implementation of this embodiment: during the crushing process, the crushing shaft 7 will drive the active bevel gear 13 to rotate, and then the driven bevel gear 14 meshing with the active bevel gear 13 will drive the fan blades 12 on the transmission shaft 11 to rotate, and the cold air sent by the fan blades 12 will enter the blower tube 15 from the air supply pipe 16, and blow into the crushing bin 2 from the opening on one side of the blower tube 15. In this way, the cold air blown into the crushing bin 2 can not only cool the crushing blade 8, but also allow the packaging bag waste to form a high-speed flow in the crushing bin 2, so that the packaging bag waste can be evenly dispersed in the crushing bin 2, and can then contact the crushing blade 8 more frequently and violently, thereby effectively improving the full uniformity of the crushing of the packaging bag waste, which is beneficial to improving the efficiency of the packaging bag waste treatment.

[0053] Example 3, reference Figure 1-5 and Figure 10-11 , this embodiment is optimized on the basis of embodiment 1, specifically: a waste material processing device for packaging bags, further comprising a separation mechanism provided on the discharge square tube 4;

[0054] Specifically, the separation mechanism includes a reversible magnetic suction component, a solenoid valve 28 installed on the discharge square pipe 4, an extraction cover 29 fixedly connected to the rear of the discharge square pipe 4, a fan base 30 welded to the rear outer wall of the discharge square pipe 4, and an extraction fan 31 fixedly installed on the bottom outer wall of the fan base 30;

[0055] Furthermore, the extraction end of the extraction fan 31 is connected to the extraction cover 29 through the extraction pipe, and the discharge end of the extraction fan 31 is fixedly connected to the crushed material discharge pipe, and the suction force generated by the operation of the extraction fan 31 can quickly extract the crushed packaging bag waste in the crushing bin 2;

[0056] More specifically, the reversible magnetic attraction assembly includes an electromagnet 33 disposed at the lower part of the discharge square tube 4 and adapted thereto, a reversing shaft 32 and a balancing shaft 37 rotatably mounted on both sides of the discharge square tube 4 in sequence, a stepping motor 34 fixedly mounted on the side wall of the discharge square tube 4, a worm 35 fixedly sleeved on the output shaft of the stepping motor 34, and a worm wheel 36 fixedly sleeved on the reversing shaft 32 and meshing with the worm 35;

[0057] Furthermore, an electric slip ring 38 is installed on the balance shaft 37. The electric slip ring 38 can facilitate the connection of the electromagnet 33 that needs to be rotated. The outer walls of the opposite ends of the flip shaft 32 and the balance shaft 37 are respectively fixed to the outer walls of both sides of the electromagnet 33.

[0058] According to the preferred technical solution, two camera holders 39 are fixedly connected to the arc inner wall of the crushing bin 2 of the present embodiment, and industrial cameras 40 are fixedly installed on the two camera holders 39. The two industrial cameras 40 are provided with fill light beads for providing a bright field of view environment for the industrial cameras 40. The two industrial cameras 40 are distributed in the upper and lower areas of the crushing bin 2;

[0059] When the above preferred solution is implemented, the two industrial cameras 40 will capture the pulverization completion status in the pulverization bin 2 in real time through visual detection technology and feed back the captured image signal to the industrial computer 41, which processes and analyzes the image signal. Finally, when the industrial computer 41 analyzes that the pulverization work in the pulverization bin 2 is completed, the solenoid valve 28, the electromagnet 33 and the suction fan 31 will be controlled to start together to start the discharging work, thereby realizing the visual monitoring effect of the material pulverization process in the pulverization bin 2, and then facilitating the control of the pulverization degree of the material, effectively reducing the situation of excessive or incomplete pulverization, thereby facilitating the treatment of waste packaging bags and achieving a good resource recycling effect.

[0060] In the specific implementation of this embodiment: through the opening of the solenoid valve 28 and the suction force generated by the operation of the suction fan 31, the packaging bag waste after the crushing in the crushing bin 2 can be sucked into the discharge square pipe 4. Under the electromagnetic suction effect of the electromagnet 33, in the process of the packaging bag waste being discharged from the extraction cover 29, some metal substances contained in the packaging bag waste that are easily attracted by the strong magnetism of the electromagnet 33 will be attracted to the electromagnet 33. Finally, the packaging bag waste extracted from the extraction cover 29 will be discharged from the crushing discharge pipe and collected by a special collecting device. The worm 35 is controlled to rotate by the stepping motor 34, and then the worm wheel 36 meshing with the worm 35 drives the flip shaft 32 to rotate, so that the metal substances adsorbed on the surface of the electromagnet 33 can be flipped out. Finally, by cutting off the power of the electromagnet 33, these metal substances are discharged from the bottom port of the discharge square pipe 4 and collected by a special collecting device.

[0061] This embodiment solves the problem that it is difficult for existing packaging bag waste processing equipment to separate some high-value metal substances contained in the waste after the discharge processing is completed, which is beneficial to improving the resource recycling value of packaging bag waste, has a better effect of turning waste into treasure, and improves the production efficiency of related enterprises.
