Description

Technical Field

[0001] This invention relates to the field of resource recycling technology, and in particular to a waste treatment device for packaging bags. Background Technology

[0002] A large amount of packaging bag waste is generated in many industrial production processes and daily life. If this packaging bag waste is discarded directly, it not only occupies a lot of space but also pollutes the environment. Therefore, specialized resource recycling companies use crushing and other processing technologies to treat this packaging bag waste, enabling it to be better transformed from waste into valuable resources. Existing packaging bag waste treatment equipment has the following problems during use:

[0003] Firstly, because the packaging bag waste entering the crushing equipment has poor fluidity, it is impossible to ensure that the packaging bag waste has frequent and intense contact with the crushing blades inside the crushing equipment, thus preventing the packaging bag waste from being crushed evenly and reducing the processing efficiency of the packaging bag waste.

[0004] Secondly, due to the wide variety of packaging bags on the market, some packaging bag waste may contain some metal materials. Existing packaging bag waste treatment equipment has difficulty separating some of the more valuable metal materials after the discharge process, thus reducing the resource recycling value of packaging bag waste and affecting the production efficiency of related enterprises.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Example 1, referring to Figure 1-5 and Figure 7-9 A waste disposal device for packaging bags includes a crushing chamber 2 welded to the upper part of a support frame 1 and an industrial control computer 41 fixedly installed on the outer wall of the front side of the crushing chamber 2.

[0041] Among them, the top of the crushing chamber 2 is fixedly connected to an L-shaped feeding cylinder 3, the L-shaped feeding cylinder 3 is equipped with a speed-controllable feeding mechanism, the crushing chamber 2 is equipped with a waste crushing and processing mechanism, and the bottom of the crushing chamber 2 is fixedly connected to a discharge square tube 4.

[0042] Specifically, the waste crushing and processing mechanism includes a motor mounting plate 5 welded to the outer wall of the front side of the crushing chamber 2, a drive motor 6 fixedly installed on the top outer wall of the motor mounting plate 5, a crushing shaft 7 rotatably installed inside the crushing chamber 2, and multiple crushing blades 8 fixedly connected to the crushing shaft 7 and distributed at equal distances. The front end of the crushing shaft 7 passes through the front side of the crushing chamber 2 and is fixedly connected to the output shaft of the drive motor 6 coaxially through a coupling.

[0043] Specifically, the speed-controllable feeding mechanism includes a drive roller 19 and a driven roller 20 that are sequentially rotated and installed in the L-shaped feeding cylinder 3, a conveyor belt 21 installed between the drive roller 19 and the driven roller 20, a variable speed control component, and a feeding hopper 27 that is fixedly connected to the top of the L-shaped feeding cylinder 3.

[0044] More specifically, the variable speed control assembly includes a protective cover 22 fixedly connected to the front outer wall of the L-shaped feeding cylinder 3, a variable speed motor 23 fixedly installed on the side wall of the protective cover 22, a drive bevel gear 24 fixedly mounted on the output shaft of the variable speed motor 23, a transmission bevel gear 25 fixedly mounted on one end of the drive roller 19 and meshing with the drive bevel gear 24, and a frequency converter 26 fixedly installed on the front outer wall of the protective cover 22. The output shaft of the variable speed motor 23 passes through one side of the protective cover 22.

[0045] In this embodiment, the packaging bag waste to be processed first enters the L-shaped feeding cylinder 3 from the feeding hopper 27. At this time, the variable speed motor 23 drives the bevel gear 24 to rotate. Then, the transmission bevel gear 25, which meshes with the drive bevel gear 24, drives the active roller 19 to rotate. With the cooperation of the driven roller 20, the conveyor belt 21 works to transport the packaging bag waste into the L-shaped feeding cylinder 3. Finally, the packaging bag waste leaves the tail end of the conveyor belt 21 and enters the crushing chamber 2 through the bottom opening of the L-shaped feeding cylinder 3 to complete the entire feeding process. The drive motor 6 controls all the crushing blades 8 on the crushing shaft 7 to rotate at high speed to fully crush the incoming packaging bag waste.

[0046] Secondly, during the feeding stage, the speed of the variable speed motor 23 can be flexibly adjusted by the frequency converter 26, and the feeding speed can be flexibly controlled according to the crushing speed of the material in the crushing chamber 2. This can avoid the situation where the material in the crushing chamber 2 is seriously accumulated due to the feeding speed being too fast, and can also avoid the situation where the material processing speed is affected due to the feeding speed being too slow.

[0047] Example 2, refer to Figure 1-6 This embodiment is an optimization based on embodiment 1. Specifically, it is a waste treatment device for packaging bags, which also includes an airflow auxiliary mechanism disposed on the crushing chamber 2.

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

[0049] More specifically, the rear end of the crushing shaft 7 passes through the rear of the crushing chamber 2 and extends into the air supply hood 9. The gear transmission assembly includes a driving bevel gear 13 fixedly mounted on one end of the transmission shaft 11 and a driven bevel gear 14 fixedly mounted on the rear end of the crushing shaft 7 and meshing with the driving bevel gear 13.

[0050] More specifically, the adjustable air supply assembly includes an air blower 15 fixedly connected to one side of the crushing chamber 2, an air supply pipe 16 fixedly connected between the air blower 15 and the air supply cover 9, a control motor 17 fixedly installed on the front outer wall of the air blower 15, and an air guide plate 18 fixedly mounted on the output shaft of the control motor 17 and located inside the air blower 15.

[0051] When the adjustable air supply assembly is in use: during the blowing process of the blower 15, the output shaft of the motor 17 drives the air guide plate 18 to rotate continuously, thereby continuously adjusting the air guide angle of the air guide plate 18, so that the blowing angle can be flexibly adjusted, making it easy to blow cold air into the crushing chamber 2 evenly.

[0052] In this embodiment, during the crushing process, the crushing shaft 7 drives the active bevel gear 13 to rotate. Subsequently, the driven bevel gear 14, which meshes with the active bevel gear 13, drives the fan blades 12 on the transmission shaft 11 to rotate. The cold air delivered by the fan blades 12 enters the blower 15 from the air supply pipe 16 and blows into the crushing chamber 2 from one side opening of the blower 15. The cold air blown into the crushing chamber 2 not only cools the crushing blades 8, but also allows the packaging bag waste to form a high-speed flow in the crushing chamber 2, which can make the packaging bag waste evenly dispersed in the crushing chamber 2, and thus more frequently and intensely contact the crushing blades 8. This effectively improves the full uniformity of the crushing of the packaging bag waste and is conducive to improving the processing efficiency of the packaging bag waste.

[0053] Example 3, referring to Figure 1-5 and Figure 10-11 This embodiment is an optimization based on embodiment 1. Specifically, it is a waste disposal device for packaging bags, which also includes a separation mechanism disposed on the discharge square tube 4.

[0054] Specifically, the separation mechanism includes a flip-up magnetic suction assembly, a solenoid valve 28 installed on the discharge square tube 4, a material extraction cover 29 fixedly connected to the rear of the discharge square tube 4, a fan base 30 welded to the rear outer wall of the discharge square tube 4, and a material extraction fan 31 fixedly installed on the bottom outer wall of the fan base 30.

[0055] Furthermore, the suction end of the suction fan 31 is connected to the suction hood 29 through the suction pipe, and the discharge end of the suction fan 31 is fixedly connected to the crushed material discharge pipe. The suction force generated by the suction fan 31 after it is running can quickly extract the crushed packaging bag waste from the crushing chamber 2.

[0056] More specifically, the flip-type magnetic suction assembly includes an electromagnet 33 located at the lower part of the discharge square tube 4 and adapted thereto, a flip shaft 32 and a balance shaft 37 rotatably mounted on both sides of the discharge square tube 4, a stepper motor 34 fixedly mounted on the side wall of the discharge square tube 4, a worm gear 35 fixedly mounted on the output shaft of the stepper motor 34, and a worm wheel 36 fixedly mounted on the flip shaft 32 and meshing with the worm gear 35.

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

[0058] In a preferred embodiment, two camera mounts 39 are fixedly connected to the inner arc of the crushing chamber 2. An industrial camera 40 is fixedly installed on each of the two camera mounts 39. Each of the two industrial cameras 40 is equipped with a supplementary light bead to provide a bright field of view environment for the industrial camera 40. The two industrial cameras 40 are distributed in the upper and lower parts of the crushing chamber 2.

[0059] When the above preferred scheme is implemented, the two industrial cameras 40 will capture the crushing status in the crushing chamber 2 in real time through visual inspection technology and feed back the captured image signals to the industrial control computer 41. The industrial control computer 41 will process and analyze the image signals. Finally, when the industrial control computer 41 analyzes that the crushing work in the crushing chamber 2 is completed, it will control the solenoid valve 28, the electromagnet 33 and the suction fan 31 to start the discharge work. This realizes the visual monitoring effect of the material crushing process in the crushing chamber 2, which makes it easier to control the degree of material crushing and effectively reduces the situation of over-crushing or incomplete crushing. This is conducive to improving the treatment effect of packaging bag waste and achieving a good resource recycling effect.

[0060] In this embodiment, the opening of the solenoid valve 28 and the suction generated by the operation of the suction fan 31 can draw the crushed packaging bag waste in the crushing chamber 2 into the discharge square pipe 4. Under the electromagnetic attraction effect of the electromagnet 33, as the packaging bag waste is discharged from the suction hood 29, some metal substances contained inside 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 suction hood 29 will be discharged from the crushed material discharge pipe and collected by a special collection device. The stepper motor 34 controls the worm 35 to rotate, and then the worm wheel 36 meshing with the worm 35 will drive the rotating shaft 32 to rotate, thereby flipping out the metal substances attracted to the surface of the electromagnet 33. Finally, by de-energizing the electromagnet 33, these metal substances are discharged from the bottom port of the discharge square pipe 4 and collected by a special collection device.

[0061] This embodiment solves the problem that existing packaging bag waste treatment equipment has difficulty separating some high-value metal substances after the discharge process, thereby improving the resource recycling value of packaging bag waste, achieving a better waste-to-treasure effect, and improving the production efficiency of related enterprises.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
