DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the embodiment of the present invention provides an environmentally friendly plastic product processing debris recovery device, including a crushing shell 1, the inner cavity of the crushing shell 1 and the inner cavity of the filter shell 901 are both provided with floating liquid, the total volume of the floating liquid in the inner cavity of the crushing shell 1 and the inner cavity of the filter shell 901 is greater than the volume of the inner cavity of the crushing shell 1, so that when the liquid control mechanism 10 draws the floating liquid in the inner cavity of the filter shell 901 into the inner cavity of the crushing shell 1, the floating liquid in the inner cavity of the crushing shell 1 can drive the crushed plastic to move to the upper surface of the screen 803 and then flow to the upper surface of the separation frame 902, so as to separate and subsequently recover plastics of different sizes, and a crushing wheel 2 is symmetrically and movably sleeved in the middle of the inner cavity of the crushing shell 1, and first gears 3 are fixedly installed at both ends of the two crushing wheels 2, and the first gears 3 on the same side are meshed with each other, and a plurality of first gears 3 are fixedly installed with a plurality of bumpers 301 at equal intervals on the circumference on the side away from the crushing shell 1, and when the bumper 301 in front of the left first gear 3 contacts the left bumper 808, The collision block 301 in front of the right first gear 3 is separated from the right collision block 808. Conversely, when the collision block 301 in front of the left first gear 3 is separated from the left collision block 808, the collision block 301 in front of the right first gear 3 contacts the right collision block 808, so that when the left first gear 3 drives the collision block 301 fixedly connected thereto to hit the left collision block 808, pushing the vibrating screen mechanism 8 to move to the right along the limiting groove of the mounting sleeve 7, the right first gear 3 drives the collision block 301 fixedly connected thereto to hit the right collision block 808, pushing the vibrating screen mechanism 8 to move to the left along the limiting groove of the mounting sleeve 7, realizing the left and right vibration of the vibrating screen mechanism 8, avoiding the subsequent feeding openings in the middle above the two movable frames 802 and the mesh holes at the bottom of the subsequent screen 803 being blocked by plastic, and the first driving member 4 is fixedly installed on the front side of the upper surface of the crushing shell 1, and the second gear 5 is fixedly installed on the output end of the first driving member 4, and the second gear 5 is meshed with its adjacent first gear 3;

[0022] A stirring mechanism 6 is provided at the bottom of the crushing shell 1, and a mounting sleeve 7 is fixedly installed on the upper surface of the crushing shell 1. A limiting groove is provided at the bottom of the inner side surface of the mounting sleeve 7. A vibrating screen mechanism 8 is provided in the middle of the mounting sleeve 7. The vibrating screen mechanism 8 includes a mounting frame 801, and the mounting frame 801 is slidably sleeved in the middle of the limiting groove. The contact surface between the mounting frame 801 and the limiting groove is a smooth surface, thereby reducing the heat generated by the friction between the mounting frame 801 and the limiting groove when the mounting frame 801 moves left and right along the limiting groove at a high frequency, thereby avoiding expansion and deformation of the mounting frame 801 and jamming. The left and right sides of the inner side surface of the mounting frame 801 are symmetrically sleeved with a movable frame 802, and a screen 803 is fixedly sleeved in the middle of the movable frame 802. The mesh diameter of the screen 803 is equal to the minimum diameter of the required plastic particles, thereby realizing the separation of plastics of different sizes, so that the plastic particles that reach the required size subsequently pass through the mesh of the screen 803 for collection, and the plastic particles larger than the mesh diameter of the screen 803 are collected. The plastic of small diameter is always under the screen 803, and will be crushed again later. A floating block 804 is fixedly installed at the bottom of the movable frame 802 near the middle of the two crushing wheels 2. The floating block 804 is made of low-density material, so as to improve the buoyancy of the floating block 804 in the floating liquid, so that the plastic can be poured into the middle of the two crushing wheels 2. At the same time, the subsequent floating liquid can push the movable frame 802 to rotate and close upward through the floating block 804, so that the screen 803 can screen the crushed plastic. The front and rear sides of the upper surface of the installation frame 801 are symmetrically fixedly installed with a first connecting block 805, the top of the first connecting block 805 is fixedly installed with a second connecting block 806, and the end of the second connecting block 806 away from the installation frame 801 is fixedly installed with a connecting plate 807, and the bottom of the connecting plate 807 is symmetrically fixedly installed with two bumping blocks 808. A filtering and separating mechanism 9 is provided on the left side of the crushing shell 1, and a liquid control mechanism 10 is provided between the filtering and separating mechanism 9 and the crushing shell 1.

[0023] like Figure 3As shown, the stirring mechanism 6 includes two mounting shafts 601, which are movably sleeved on the front and rear sides of the bottom of the crushing shell 1, and the outer curved surfaces of the two mounting shafts 601 are fixedly installed with a plurality of stirring blades 602 at equal intervals around the circumference. The right ends of the two mounting shafts 601 are fixedly installed with third gears 603, and the right side of the crushing wheel 2 is movably sleeved with a gear set 604. The third gears 603 on the front and rear sides are meshed with the adjacent gear sets 604. The gear set 604 is composed of an even number of gears, so that the two third gears 603 meshed with the gear set 604 are meshed. 3. The second driving member 605 is fixedly mounted on the right side of the crushing shell 1, and the output end of the second driving member 605 is fixedly mounted with a fourth gear 606, which is meshed with the adjacent third gear 603.

[0024] like Figure 1 and Figure 2 As shown, the filtering and separating mechanism 9 includes a filtering shell 901, which is fixedly mounted on the left side of the crushing shell 1, a separating frame 902 is fixedly sleeved on the upper part of the inner cavity of the crushing shell 1, a separating net 903 is fixedly sleeved on the middle part of the separating frame 902, and the separating net 903 is inclined to the left, and a filtering block 904 is fixedly sleeved on the inner cavity of the filtering shell 901, and the filtering block 904 is arranged along the bottom left side and the top right side of the inner cavity of the filtering shell 901, thereby increasing the contact area between the filtering shell 901 and the floating liquid to be filtered above it, improving the filtering efficiency of the filtering shell 901, and making the floating liquid in the inner cavity of the filtering shell 901 and the inner cavity of the crushing shell 1 circulate stably through the liquid control mechanism 10.

[0025] like Figure 1 and Figure 5 As shown, the liquid control mechanism 10 includes a water pump 1001, which is fixedly installed at the bottom of the front side of the filter housing 901, the input end of the water pump 1001 is fixedly connected to the filter housing 901, and the output end of the water pump 1001 is fixedly installed with a conduit 1002, the conduit 1002 is fixedly connected to the bottom of the crushing shell 1, and the right port of the conduit 1002 is fixedly connected with an isolation net 1003, and the mesh diameter of the isolation net 1003 is smaller than the diameter of the smallest plastic after crushing, so as to avoid that when the water pump 1001 rotates in the opposite direction and the floating liquid in the inner cavity of the crushing shell 1 flows to the inner cavity of the filter housing 901, the plastic in the floating liquid in the inner cavity of the crushing shell 1 flows into the middle part of the water pump 1001 together with the floating liquid, causing damage to the water pump 1001.

[0026] Working principle:

[0027] When the present invention is used, firstly, floating liquid is poured into the inner cavity of the crushing shell 1 and the filter shell 901, so that the liquid height of the floating leaves is slightly lower than the bottom surface of the crushing wheel 2, and then the first driving member 4 is started. The output end of the first driving member 4 drives the second gear 5 to rotate, and the second gear 5 drives the first gear 3 on the left side to rotate, and the first gear 3 on the left side drives the first gear 3 on the right side to rotate, and the first gears 3 on the left and right sides drive the two crushing wheels 2 above to rotate in the opposite direction. At the same time, when the two first gears 3 rotate, the two first gears 3 both drive the collision block 301 fixedly connected thereto to rotate, and because the rotation directions of the two first gears 3 are opposite, when the first gear 3 on the left side drives the collision block 301 fixedly connected thereto to hit the collision block 808 on the left side, and pushes the vibrating screen mechanism 8 to move to the right along the limiting groove of the installation sleeve 7, the first gear 3 on the right side drives the collision block 301 fixedly connected thereto to hit the collision block 808 on the right side, and pushes the vibrating screen mechanism 8 to move to the left along the limiting groove of the installation sleeve 7, thereby realizing the left-right vibration of the vibrating screen mechanism 8, and then the plastic is removed from the positive side of the crushing shell 1. The plastic is poured into the middle of the two crushing wheels 2 along the screen 803 from above. At this time, the crushing wheels 2 rotating in opposite directions crush the plastic. At the same time, the vibrating screen mechanism 8 vibrates left and right to prevent the plastic above the screen 803 from accumulating on the top of the screen 803, causing the discharge port in the middle of the two movable frames 802 to be blocked, resulting in the plastic being unable to fall into the middle of the two crushing wheels 2, causing the crushing efficiency of the crushing wheels 2 to be reduced. When the plastic crushed by the crushing wheels 2 falls above the floating liquid in the inner cavity of the crushing shell 1 below the crushing wheels 2, the second driving member 605 is started at this time, and the output end of the second driving member 605 drives the gear set 604 to rotate, and the gear set 604 drives the third gear 603 on the right to rotate. The third gear 603 on the right drives the third gear 603 on the left to rotate through the gear set 604. The two third gears 603 drive the two mounting shafts 601 to rotate in opposite directions. The two mounting shafts 601 drive the stirring blades 602 fixedly connected thereto to stir the floating liquid in the inner cavity of the crushing shell 1 and the crushed plastic, so that after crushing, the dirt on the surface of the plastic is separated from the plastic.

[0028] When the plastics above the two crushing wheels 2 are crushed, the water pump 1001 is then started in the forward direction. The water pump 1001 draws the floating liquid in the inner cavity of the filter shell 901 into the inner cavity of the crushing shell 1 through the conduit 1002, so that the floating liquid level in the inner cavity of the crushing shell 1 rises, and the floating liquid in the inner cavity of the crushing shell 1 pushes the plastics floating on the floating liquid after crushing to move upward, and at the same time, the first driving member 4 is started in the reverse direction to make the lower parts of the two crushing wheels 2 rotate towards each other. At this time, as the floating liquid level rises, the floating liquid pushes the plastics floating on the floating liquid after crushing to contact the two crushing wheels 2 again, and the crushing wheels 2 crush the crushed plastics again. When the floating liquid level is higher than the crushing wheel 2, the floating liquid pushes the movable frame 802 to rotate upward and close through the floating block 804. At this time, the floating liquid pushes the plastics with a size smaller than the aperture of the screen 803 after being crushed again to pass through the screen 803 and move to the top of the screen 803. At the same time, the vibrating screen mechanism 8 that vibrates left and right can prevent the large particles of plastic on the bottom of the screen 803 from clogging the screen 803 The mesh holes at the bottom allow the small-sized plastics at the bottom of the screen 803 to pass through the large-sized plastics and move to the top of the screen 803, thereby reducing the amount of small-sized plastics that are subsequently crushed, and improving the efficiency of subsequent crushing. At the same time, the small-sized plastics above the screen 803 follow the floating liquid flow above the screen 803 after being crushed to the upper surface of the separation net 903. The plastics on the upper surface of the separation net 903 slide along the upper surface of the separation net 903 to the collection device on the left side of the separation net 903. The floating liquid that flows through the upper surface of the separation net 903 flows to the upper surface of the filter block 904 through the separation net 903. After being filtered by the filter block 904, it flows into the inner cavity of the crushing shell 1 again through the liquid control mechanism 10, so that the floating liquid level in the inner cavity of the crushing shell 1 continues to rise, thereby filtering the floating liquid, removing dirt in the floating liquid, reducing the frequency of replacing the floating liquid, reducing production costs, and improving production efficiency. At the same time, the crushed plastics are kept in a clean state;

[0029] When the plastic at the bottom of the two crushing wheels 2 is crushed again, the liquid control mechanism 10 is then started in reverse to pump the floating liquid in the inner cavity of the crushing shell 1 into the inner cavity of the filter shell 901, so that the floating liquid level in the inner cavity of the crushing shell 1 is lowered. At this time, the crushed plastic contacts the crushing wheel 2 from above again, and the crushing wheel 2 crushes the plastic, thereby repeatedly crushing the plastic until all the crushed plastic passes over the screen 803 and moves to the upper surface of the separation net 903, thereby overcoming the problem that in order to crush the plastic to the required size, the existing crushing device needs to repeatedly crush, collect, screen, collect and crush the crushing device and the screening device, resulting in a large number of repeated and cumbersome processes, resulting in poor crushing efficiency and high labor costs.
