Description

Technical Field

[0001] The invention belongs to the technical field of modified plastic pulverization, and in particular relates to a pulverization device and a method thereof for modified plastic engineering recycling technology. Background Art

[0002] Modified plastics engineering recycling refers to the process of modifying plastic materials to make them have better performance and use value, and then recycling them after use. This process can not only improve the performance and durability of plastics, but also effectively reduce the pollution of plastic waste to the environment and promote the sustainable use of resources. With the improvement of global environmental awareness, the recycling and reuse of plastics has become an important topic in modern materials science research. Modified plastics are modified by physical, chemical or blending methods to meet different application requirements, such as improving their strength, heat resistance, corrosion resistance, flame retardancy, etc. Modified plastic products have a longer service life and can be reprocessed into new plastic materials after use through advanced recycling technologies, such as mechanical recycling, chemical recycling and other methods.

[0003] When modified plastics are recycled, the crushing process is an extremely important measure. When the existing crushing device used for modified plastic engineering recycling technology is in use, its crushing roller cannot change the distance during use, resulting in a single processing of the modified plastics. At the same time, the plastic cannot be fully crushed after the first crushing, thereby reducing the working performance of the plastic crushing device. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a pulverizing device and method for modified plastic engineering recycling technology.

[0005] The technical solution adopted to solve the above technical problems is: a crushing device for modified plastic engineering recycling technology, comprising a main body, a bottom of the main body is fixedly connected to a base frame, a top of the main body is fixedly connected to a hopper, and a driving mechanism is installed inside the main body;

[0006] An adjusting mechanism is installed inside the main body, a secondary crushing mechanism is installed on one side of the driving mechanism, a discharge port is opened inside the main body and the base frame, and an insert is slidably connected inside the base frame and the discharge port.

[0007] Furthermore, the driving mechanism includes a fixed block fixedly connected to the top of the base frame, one side of the fixed block is fixedly connected to a motor, and two support shafts are rotatably connected inside the main body, one of the support shafts is fixedly connected to a first gear on its outer wall, the first gear is meshed with a second gear, the second gear is meshed with a third gear, one side of the third gear is fixedly connected to a first crushing roller, the third gear is meshed with a fourth gear, the fourth gear is meshed with a fifth gear, the fifth gear is meshed with a sixth gear, and one side of the sixth gear is fixedly connected to a second crushing roller, one end of one of the support shafts is fixedly connected to an output end of the motor, the other end of the first crushing roller is rotatably connected to the main body, and the other end of the second crushing roller is rotatably connected to the main body.

[0008] Through the above technical solution, when in use, the motor on one side of the fixed block is started to drive the first gear on the outer wall of one of the support shafts to rotate, and under the engagement of the first gear, the second gear and the third gear, the first crushing roller is driven to rotate, and under the engagement of the fourth gear, the fifth gear and the sixth gear, the second crushing roller can be smoothly driven to rotate, and under the rotation of the driving mechanism, the entire crushing device can be smoothly driven to a normal crushing state.

[0009] Furthermore, the adjusting mechanism includes a hydraulic cylinder fixedly connected to the front and rear ends of the main body, wherein one of the piston ends of the hydraulic cylinder is rotatably connected to a first connecting rod, the first node of the first connecting rod is rotatably connected to a second connecting rod, the other end of the second connecting rod is rotatably connected to a third connecting rod, the other end of the third connecting rod is rotatably connected to a fourth connecting rod, the other end of the fourth connecting rod is rotatably connected to a fifth connecting rod, the second node of the first connecting rod is rotatably connected to the second gear, the third node of the first connecting rod is rotatably connected to the first gear, the junction of the second and third connecting rods is rotatably connected to the fourth gear, the other end of the third connecting rod is rotatably connected to the fifth gear, the bottom node of the fifth connecting rod is rotatably connected to another support shaft, and the top node of the fifth connecting rod is rotatably connected to another hydraulic cylinder.

[0010] Through the above technical scheme, under the operation of the driving mechanism, the adjustment mechanism is used to cooperate with it, and selection is made according to the particle standard of the modified plastic, so that the particle spacing can be changed. Specifically, when one of the hydraulic cylinders is started, its piston end will retract the first connecting rod to one side, so that the first connecting rod drives the third gear and the first crushing roller to rotate tiltedly toward the rear end with one of the support shafts as the center. If further expansion is required, another hydraulic cylinder is started to retract the fifth connecting rod toward the front end and rotate tiltedly with the other support shaft as the center, so as to achieve a change in distance.

[0011] Furthermore, the secondary crushing mechanism includes a first universal joint fixedly connected to one side of the fifth gear, one side of the first universal joint is fixedly connected to a limiting telescopic rod, the other end of the limiting telescopic rod is fixedly connected to a second universal joint, one side of the second universal joint is fixedly connected to a third crushing roller, and the other end of the third crushing roller is rotatably connected to the main body.

[0012] Through the above technical scheme, during the process of crushing and adjusting, the secondary crushing mechanism can be used to crush the modified plastic that is not fully crushed in the first time, so as to improve the crushing quality of the modified plastic. Specifically, at this time, under the rotation of the fifth gear, the second universal shaft at the other end of the limiting telescopic rod will be driven to rotate, and at the same time, the third crushing roller will cooperate with the first crushing roller to crush the modified plastic for the second time. As the adjustment changes, the particle spacing between the third crushing roller and the first crushing roller also changes.

[0013] A comminution method for modified plastics engineering recycling technology comprises the following specific steps:

[0014] Step 1: First, put the modified plastic to be processed into the hopper. At this time, according to the plastic processing requirements, one of the hydraulic cylinders is started, and its piston end will retract the first connecting rod to one side, so that the first connecting rod drives the third gear and the first crushing roller to rotate toward the rear end with one of the support shafts as the center. If it needs to be further expanded, another hydraulic cylinder is started to retract the fifth connecting rod toward the front end to rotate with another support shaft as the center, so as to realize the selection of the particle size of the modified plastic crushing;

[0015] Step 2: After the preparation work is completed, the motor on one side of the fixed block is started to drive the first gear on the outer wall of one of the support shafts to rotate, and the first crushing roller is driven to rotate under the meshing of the first gear, the second gear and the third gear, and the second crushing roller is smoothly driven to rotate under the meshing of the fourth gear, the fifth gear and the sixth gear, and the connection of the second connecting rod and the third connecting rod;

[0016] Step 3: While the first crushing roller and the second crushing roller are crushing, the rotation of the fifth gear will drive the second universal shaft at the other end of the limiting telescopic rod to rotate, and the third crushing roller will cooperate with the first crushing roller to crush the modified plastic for the second time. As the processing of the modified plastic is completed, the operator pulls the insert to make the plastic particles flow out from the discharge port.

[0017] The beneficial effects of the present invention are as follows: (1) By designing a driving mechanism, an adjusting mechanism and a secondary pulverizing mechanism, the present invention can select a pulverizing standard according to the processing requirements of the modified plastics during the process of the modified plastics engineering recycling technology, and if the initial pulverizing is insufficient, it can be pulverized again to ensure that the standard of the modified plastics can be further qualified; (2) By designing a driving mechanism and a secondary pulverizing mechanism, the present invention can enable the pulverizing roller to smoothly pulverize the modified plastics during the pulverizing process, and at the same time, when the pulverizing specifications are adjusted, it can not only maintain the pulverizing again and maintain the pulverizing sufficient, but also keep the pulverizing standard the same as the initial pulverizing standard in this state; (3) By designing an adjusting mechanism, the present invention can adjust according to the required plastic processing specifications during the pulverizing process of the modified plastics, and adjust the distance between the pulverizing rollers according to the different requirements of different plastic materials for the pulverizing particle size. The adjustable pulverizing roller distance can ensure the uniformity of the final pulverized product, thereby facilitating the smooth progress of the subsequent modification process and improving the performance and quality of the modified plastics.
