Description

Technical Field

[0001] The present invention relates to the technical field of EPS recycling, in particular to an EPS waste recycling device. Background Art

[0002] EPS waste refers to discarded expanded polystyrene materials. Due to its large volume, it is first crushed and then compressed during recycling. When crushing EPS materials, although the hardness of EPS is relatively low, a large amount of crushed materials and the cutting tool continue to rub at high frequencies, forming an effect similar to sandpaper polishing, resulting in blade blunting. At the same time, some EPS contain flame retardants (such as hexabromocyclododecane) or fillers (such as talcum powder). These hard particles will accelerate tool wear, and the blade mainly relies on shear force to break during crushing. Since the force is concentrated at a single point on the tool, it is prone to local wear, which affects the service life of the tool. Summary of the Invention

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1: Reference Figure 1-8 A device for recycling and utilizing EPS waste includes a shell 1, on which a crushing roller 7 is rotatably connected through a bearing, and a plurality of double-edged cutters 8 are fixedly connected to the crushing roller 7; a subsequent processing device is connected to the shell 1, and the subsequent processing device includes a conveyor 2, a briquetting machine 3, and a discharge channel 4. The conveyor 2 is connected to the shell 1, and the conveyor 2 can be specifically a screw conveyor for conveying the crushed particles. The conveyor 2 is connected to the briquetting machine 3, and the discharge end of the briquetting machine 3 is connected to the discharge channel 4. The conveyor 2 conveys the crushed material to the briquetting machine 3, and the briquetting machine 3 squeezes the crushed material into blocks to reduce the volume, and finally discharges it from the discharge channel 4.

[0029] The crushing roller 7 and the rotating roller 15 are both fixedly connected to the first pulley 9, and the rotating roller 15 is rotatably connected to the housing 1 through a bearing. The two first pulleys 9 are sleeved with a first belt 10, which plays a role in transmission connection between the crushing roller 7 and the rotating roller 15.

[0030] The first friction wheel 11 is fixedly connected to the rotating roller 15, and the motor 6 is installed on the housing 1. The motor 6 is connected to the connecting shaft 30 for transmission. The second friction wheel 12 is fixedly connected to the connecting shaft 30, and the third friction wheel 31 is fixedly connected to the connecting shaft 30. The third friction wheel 31 abuts the fourth friction wheel 32. The fourth friction wheel 32 is fixedly connected to the rotating rod 34. The rotating rod 34 is rotatably connected to the mounting plate 33 through a bearing. The mounting plate 33 is rotatably connected to the connecting shaft 30 through a bearing. The second friction wheel 12 and the fourth friction wheel 32 abut against the first friction wheel 11 through an alternating mechanism; when the motor 6 rotates, the connecting shaft 30 is driven to rotate, and the connecting shaft 30 drives the second friction wheel 12 and the third friction wheel 31 to rotate at the same time. When the second friction wheel 12 abuts against the first friction wheel 11, it drives the first friction wheel 11 Rotation, the rotation direction of the first friction wheel 11 is opposite to the rotation direction of the motor 6. When the fourth friction wheel 32 abuts against the first friction wheel 11, it drives the fourth friction wheel 32 to rotate. The rotation direction of the fourth friction wheel 32 is opposite to the rotation direction of the motor 6. When the fourth friction wheel 32 drives the first friction wheel 11 to rotate, the rotation direction of the first friction wheel 11 is the same as the rotation direction of the motor 6, so that the rotating roller 15 switches forward and reverse, so that the double-edged cutter 8 switches the double edges when crushing, and the cutting edges on both sides bear the cutting load in turn, and the double edges exchange wear. At the same time, the direction of the cutting force changes periodically to avoid stress concentration in a single direction, and the original force-bearing side temporarily leaves the high friction state during reversal, and heat is conducted and dissipated through the tool base, reducing the occurrence of thermal cracks in the tool, which is beneficial to extending the service life of the tool.

[0031] A limiting rod 37 is fixedly connected to the mounting plate 33, and a limiting sleeve 36 is sleeved on the limiting rod 37. The limiting sleeve 36 is fixedly connected to the housing of the motor 6. The limiting rod 37 and the limiting sleeve 36 limit the mounting plate 33, so that the mounting plate 33 cannot rotate, thereby ensuring that the third friction wheel 31 is always in contact with the fourth friction wheel 32.

[0032] Example 2: In Example 1, when switching between forward and reverse rotation, the forward rotation time is likely to be the same. However, when reversing, the crushing roller 7 drives the double-edged cutter 8 to reverse, which will cause a large amount of crushed EPS fragments to be thrown back into the feeding area due to reverse rotation, resulting in repeated crushing, which greatly reduces the crushing efficiency. Figure 2-8 As another preferred embodiment of the present invention, on the basis of Example 1, a connecting cavity is opened on the connecting shaft 30, a connecting groove is opened on the inner wall of the connecting cavity, a driving shaft 29 is arranged in the connecting cavity, a boss 38 is fixedly connected to the driving shaft 29, the boss 38 is located in the connecting groove, the driving shaft 29 is fixedly connected to the output shaft of the motor 6, when the connecting shaft 30 moves along the axial direction, the position of the boss 38 in the connecting groove will be adjusted, ensuring that when the driving shaft 29 rotates, it will drive the connecting shaft 30 to rotate coaxially.

[0033] The alternating mechanism includes a connecting part 18, which is rotatably connected to the second friction wheel 12 through a bearing, and a roller 17 is provided on the connecting part 18. A fixing frame 14 is fixedly connected to the subsequent processing device, and a movable plate 13 is connected to the fixing frame 14 through a horizontal displacement mechanism. A slide 16 is provided on the movable plate 13, and the roller 17 is located in the slide 16. The slide 16 is divided into a front end, a middle section and a rear end. The middle section of the slide 16 is inclined to connect the front end and the rear end. When the roller 17 enters the middle position, the second friction wheel 12 and the fourth friction wheel 32 will not contact the first friction wheel 11. Since the first friction wheel 11 has a certain rotation speed, the first friction wheel 11 continues to rotate under the action of inertia to avoid affecting the crushing process.

[0034] The front and rear ends of the slideway 16 are arranged horizontally. When the reciprocating threaded rod 19 rotates, the position of the fixed ear 28 on the reciprocating threaded rod 19 is adjusted, thereby driving the movable plate 13 to move, so that the roller 17 slides in the slideway 16. When the roller 17 moves from the front end to the rear end, the connecting portion 18 moves along the axis of the driving shaft 29, driving the connecting shaft 30 to move, and the fourth friction wheel 32 abuts against the first friction wheel 11. When the roller 17 enters from the rear end to the front end of the slideway 16, the fourth friction wheel 32 disengages from the first friction wheel 11, and the second friction wheel 12 is disengaged from the first friction wheel 11. The friction wheels 11 abut against each other, thereby switching the rotation direction of the first friction wheel 11 and the rotation direction of the double-edged cutter 8. Moreover, since the front end length of the slideway 16 is greater than the rear end length, the time when the second friction wheel 12 abuts against the first friction wheel 11 is greater than the time when the fourth friction wheel 32 abuts against the first friction wheel 11. As a result, during crushing, the forward rotation time of the double-edged cutter 8 is significantly longer than the reverse rotation time, thereby reducing the amount of crushed EPS fragments thrown back into the feed area, reducing the amount of re-crushing, and reducing the impact of reversal on crushing efficiency.

[0035] The horizontal displacement mechanism includes a reciprocating threaded rod 19, which is rotatably connected to the fixed frame 14 through a bearing. A fixed ear 28 is threaded through the reciprocating threaded rod 19, and the fixed ear 28 is fixedly connected to the movable plate 13. A first bevel gear 25 is fixedly connected to the reciprocating threaded rod 19, and a second bevel gear 27 is engaged with the first bevel gear 25. The second bevel gear 27 is connected to the driving shaft 29 through a reduction mechanism, and the driving shaft 29 is driven to rotate by the rotation of the motor 6, so that the driving shaft 29 drives the rotating shaft 26 to rotate under the action of the reduction mechanism, and the rotating shaft 26 drives the second bevel gear 27 to rotate. The second bevel gear 27 drives the first bevel gear 25 to rotate, and the first bevel gear 25 drives the reciprocating threaded rod 19 to rotate.

[0036] A limiting through slot is provided on the movable plate 13, and a limiting square column 20 is arranged in the through slot. The limiting square column 20 is fixedly connected to the fixed frame 14. When the movable plate 13 moves, the limiting square column 20 will be driven to move in the limiting through slot, thereby ensuring the stability of the movable plate 13 during movement and supporting the movable plate 13 at the same time.

[0037] Example 3: During the crushing process, the general rotation speed of the crushing roller 7 is 800-1500 rpm, which causes the movable plate 13 to move back and forth many times within one minute, causing the crushing roller 7 to switch between forward and reverse rotations many times within one minute. The friction wheel, pulley, and belt transmission components are repeatedly subjected to reverse torque, which is prone to breakage, affecting the service life of the friction wheel, pulley, and belt transmission components. Figure 4-8 As another preferred embodiment of the present invention, based on Example 2, the reduction mechanism includes a third pulley 35, the third pulley 35 is fixedly connected to the driving shaft 29, the fixed frame 14 is rotatably connected to a support shaft 39 through a bearing, the support shaft 39 is fixedly connected to an incomplete gear 24 and a second pulley 22, a second belt 21 is sleeved between the second pulley 22 and the third pulley 35, the second bevel gear 27 is fixedly connected to a rotating shaft 26, the rotating shaft 26 is rotatably connected to the fixed frame 14 through a bearing, the rotating shaft 26 is fixedly connected to a gear 23, the gear 23 is meshed with the incomplete gear 24, and the motor 6 rotates, driving the third pulley 35 to rotate. Since the diameter of the third pulley 35 is smaller than that of the second pulley 22, the second pulley 22 plays a role of preliminary deceleration. The second pulley 22 drives the incomplete gear 24 to rotate, and the incomplete gear 24 intermittently drives the gear 23 to rotate, which increases the time for the gear 23 to rotate one circle, causing the rotating shaft 26 to rotate slowly, thereby slowly rotating the reciprocating threaded rod 19 and causing the movable plate 13 to reciprocate once within a few minutes, reducing the number of times the transmission components are repeatedly subjected to reverse torque, which is beneficial to reducing the impact on the service life of the friction wheel, pulley, and belt transmission components.

[0038] A protective shell 5 is fixedly connected to the housing 1. The incomplete gear 24, the second pulley 22, and the third pulley 35 are located inside the protective shell 5, which prevents the transmission components from being exposed and is beneficial to safety during operation.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
