[0002] An integrated machine for screening and crushing plastic raw materials is a mechanical device integrating screening and crushing functions, mainly used for processing plastic raw materials, and realizing efficient processing and resource recycling of raw materials through an automated process.

[0003] After retrieval, a Chinese patent with the publication number CN208758018U discloses a plastic particle screening device, which includes a screening box and a feeding box. The top of the screening box is provided with a feeding port. A sieve plate is fixedly arranged inside the screening box. A support plate is arranged at the bottom of the sieve plate. A plurality of meshes are arranged between the sieve plate and the support plate. An elastic ball is arranged in each mesh. A first conveyor belt is arranged at the bottom of the support plate. Vibration motors are arranged at the bottom ends on both sides of the screening box. A shock-absorbing base is arranged at the bottom end of the screening box. An aggregate box is arranged on one side of the screening box. The above solution facilitates the automatic feeding of plastic particles through the provided feeding box and the second conveyor belt, replaces manual feeding, improves work efficiency, and reduces the labor intensity of workers; the automatic opening or closing of the feeding box door is facilitated through the provided box door adjusting mechanism, and the pushing mechanism facilitates pushing the plastic particles in the feeding box into the screening box. However, when the above solution is actually used, there are still the following deficiencies:

Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] Refer to Figures 1 - 12 , a plastic raw material screening and crushing integrated machine, including a frame 11, a crushing device 12 is arranged on the frame 11, a discharge port 121 is opened on the crushing device 12, a screening component is arranged on the frame 11, the screening component includes a bottom frame 21, a vibrating frame 22 and a side frame 23, the vibrating frame 22 is slidably arranged on the bottom frame 21, and a screen is arranged on the vibrating frame 22, the side frame 23 is fixed on the top surface of the vibrating frame 22, and rotating shafts 24 are fixed at both ends of the bottom frame 21, and both rotating shafts 24 are rotatably installed on the frame 11.

[0044] A shielding component is arranged on the frame 11 for shielding the discharge port 121. The shielding component includes an outer cylinder 43, a baffle 41 and a cylinder 42. The baffle 41 is arranged opposite to the discharge port 121, and a fixing block 47 is fixed to the bottom surface of the baffle 41.

A first ejector rod 46 is fixed to the first sliding plug 44, and one end of the first ejector rod 46 extends to the outside of the outer cylinder 43 and is fixedly connected to the fixing block 47.

[0045] A collecting component is arranged on the frame 11 for collecting the screened plastic particles. The collecting component includes two collecting boxes 71, a mounting frame 72 and a guide plate 73. The two collecting boxes 71 are both arranged at the bottom of the frame 11, and the two collecting boxes 71 are arranged side by side. The mounting frame 72 is fixed to the frame 11 and is located above the two collecting boxes 71. A rotatable guide plate 73 is arranged on the mounting frame 72.

A second gear 75 is fixedly sleeved at the end position of the shaft rod 74, and the second gear 75 meshes with the second rack 76.

[0046] When the plastic raw material screening and crushing integrated machine proposed by the present invention is in use, the staff first put the plastic products into the crushing device 12, and the crushing device 12 performs crushing treatment on the plastic products. After the crushing is completed, the plastic particles are discharged through the discharge port 121, completing the crushing process of the plastic products. Further, the plastic particles will fall on the vibrating screen mesh, and the screen mesh performs screening treatment on the plastic particles. It should be noted that a vibration module for driving the vibrating frame 22 and the screen mesh to vibrate is arranged on the bottom frame 21. The specific structure and working principle of the vibration module are prior art, and the implementation method adopts conventional means, which are not shown in the figure and will not be elaborated here. After screening, some plastic particles pass through the screen mesh, and the remaining plastic particles remain on the screen mesh. In the initial state, the guide plate 73 is in an inclined state. At this time, the plastic particles falling on the guide plate 73 will slide along the inclined guide plate 73 into one of the collecting boxes 71, realizing the collection of the plastic particles.

[0047] The frame 23 is provided with a push-flat component for pushing flat the plastic particles accumulated on the screen. The push-flat component includes a fixed frame 31, a rotating cylinder 32, a slide rod 33 and a motor 38. The fixed frame 31 is fixed to the frame 23 and has a U-shaped structure. A hole is provided in the middle of the fixed frame 31. The rotating cylinder 32 is rotatably installed in the hole. The upper and lower ends of the rotating cylinder 32 are open. The slide rod 33 slides in the rotating cylinder 32. The outer peripheral surface of the slide rod 33 fits with the inner surface of the rotating cylinder 32. The end of the slide rod 33 away from the screen is rounded. A collar 34 is fixed to the top of the slide rod 33, and a spring 38 is provided between the collar 34 and the rotating cylinder 32. 5 are connected, a plurality of slapping plates 36 are fixed to one end of the slide rod 33 away from the ring 34, and a pushing plate 37 is fixed to each slapping plate 36. Each slapping plate 36 is arranged in the horizontal direction, and each pushing plate 37 is arranged in the vertical direction. The plurality of slapping plates 36 are distributed in a circumferential array around the rotating cylinder 32, and a motor 38 is installed on the side of the frame 23, and the output shaft of the motor 38 is connected to the rotating cylinder 32 through a transmission member 39, and the transmission member 39 adopts a belt drive transmission method.

[0048] A flip assembly is provided on the frame 23 for flipping the screen. The flip assembly includes an outer cylinder 2 53. The outer cylinder 2 53 is connected to the outer cylinder 1 43 through a connecting pipe 48. An electromagnetic valve 49 is installed on the connecting pipe 48. The flip assembly also includes a gear 1 51 and a rack 1 52. The gear 1 51 is fixedly sleeved on one of the rotating shafts 24. The outer cylinder 2 53 is fixed on the frame 11. A sliding plug 2 54 is provided inside the outer cylinder 2 53 for sealing and sliding. The sliding plug 2 54 and the outer cylinder 2 53 are connected by a spring 3 55. A push rod 2 56 is fixed on the sliding plug 2 54. One end of the push rod 2 56 extends to the outside of the outer cylinder 2 53 and is connected to the rack 1 52. The rack 1 52 and the gear 1 51 are meshed.

[0049] The present invention has the function of automatically cleaning the plastic particles accumulated on the screen. Specifically, when too many plastic particles are accumulated on the screen, the cylinder 42 is operated and drives the outer cylinder 43 to move. Figure 2 and Figure 9As shown, in the initial state, the baffle 41 and the discharge port 121 are offset from each other. At this time, the baffle 41 does not block the discharge port 121. The first sliding plug 44 is located at the end of the first outer cylinder 43 away from the cylinder 42, and there is oil stored between the first sliding plug 44 and the first outer cylinder 43. When the cylinder 42 operates, the cylinder 42 can drive the first outer cylinder 43 to move. Under the elastic force of the second spring 45, the first outer cylinder 43 can drive the first sliding plug 44 and the first ejector rod 46 to move, causing the baffle 41 to move and block the discharge port 121. When the baffle 41 completely blocks the discharge port 121, the broken plastic particles cannot fall through the discharge port 121 and will temporarily accumulate on the baffle 41. At this time, the baffle 41 moves to the extreme position, that is, the baffle 41 cannot move further. Further, when the cylinder 42 continues to operate, since the baffle 41 cannot move, the first ejector rod 46 and the first sliding plug 44 cannot move either, but the first outer cylinder 43 continues to move. During this process, the first outer cylinder 43 can move relative to the first sliding plug 44. Then, the solenoid valve 49 is energized and conducted, and at this time, the oil between the first outer cylinder 43 and the first sliding plug 44 can enter the second outer cylinder 53 through the connecting pipe 48.

[0050] When the oil enters the second outer cylinder 53, the oil can push the second sliding plug 54 to move, and the second ejector rod 56 also moves accordingly. When the second ejector rod 56 moves, the second ejector rod 56 can drive the first rack 52 to move, causing the first rack 52 to drive the first gear 51 to rotate. When the first gear 51 rotates, it drives the corresponding rotating shaft 24 to rotate, and finally causes the bottom frame 21 to rotate. During the process of the first rack 52 driving the first gear 51 to rotate, the bottom frame 21 just rotates 180°, realizing the automatic flipping of the screen. Based on the above process, during the operation of the cylinder 42, the baffle 41 first blocks the discharge port 121, and then the screen automatically flips. Through this design, it is possible to prevent plastic particles from still falling downward during the flipping of the screen. In addition, during the flipping of the screen, the electric push rod operates and drives the second rack 76 to move. When the second rack 76 moves, it can drive the second gear 75 to rotate, causing the shaft rod 74 to rotate. When the shaft rod 74 rotates, the guide plate 73 rotates accordingly, changing the inclination direction of the guide plate 73. In this case, the plastic particles accumulated on the screen can slide into another collection box 71 through the guide plate 73, realizing the automatic collection of the plastic particles accumulated on the screen. In summary, the present invention realizes the automatic collection of the plastic particles accumulated on the screen through the automatic flipping of the screen and the automatic flipping of the guide plate 73. The whole process does not require manual intervention and does not require shutdown, which not only ensures the working efficiency of the device but also reduces the labor intensity of the staff.

[0051] For the screen mesh, the present invention provides a flattening component. Specifically, during the screening process, the motor 38 operates and drives the rotating cylinder 32 to rotate through the transmission member 39. When the rotating cylinder 32 rotates, the sliding rod 33 rotates accordingly and drives a plurality of flapping plates 36 and a plurality of flattening plates 37 to rotate synchronously. During the rotation process, the plurality of flattening plates 37 can flatten the plastic particles piled up together, making the plastic particles evenly spread on the screen mesh. The function of the flattening plate 37 can prevent the plastic particles from overly accumulating in a local area of the screen mesh, enabling the particles to be evenly distributed on the surface of the screen mesh, increasing the contact area with the screen mesh holes, thereby accelerating the screening speed, reducing the situation where particles cannot pass through the screen mesh in time due to accumulation, and improving the screening productivity. At the same time, the evenly distributed particles contribute to improving the screening accuracy, reducing mis-screening or missed-screening phenomena, ensuring that the particles meeting the specifications smoothly pass through the screen mesh, and effectively separating the particles not meeting the specifications, guaranteeing the quality stability of the product after screening. In addition, the uniform particle distribution can relieve the local pressure on the screen mesh, reduce the risk of the screen mesh being damaged due to excessive local stress, extend the service life of the screen mesh, reduce the frequency and cost of screen mesh replacement, reduce the equipment maintenance pressure, and make the entire screening process more smooth and efficient.

[0052] A flapping component is arranged on the frame 11 for flapping the screen mesh. The flapping component includes a guide sleeve 61, a movable rod 62 and an eccentric wheel 66. The guide sleeve 61 is fixed on the frame 11. The movable rod 62 is slidably arranged in the guide sleeve 61. One end of the movable rod 62 is fixed with an arc-shaped plate 63, and the other end is fixed with a movable plate 65. An arc surface is arranged on the arc-shaped plate 63, and an inclined surface is arranged on the movable plate 65. The arc-shaped plate 63 is connected with the frame 11 through a tension spring 64. The eccentric wheel 66 is fixedly sleeved on the output shaft of the motor 38.

[0053] When flipping and cleaning the plastic particles, when the screen mesh is flipped by 180°, as Figure 7 shown, the sliding rod 33 just moves to a position directly opposite to the movable plate 65, and the eccentric wheel 66 just moves to a position directly opposite to the arc-shaped plate 63. In this case, when the eccentric wheel 66 rotates under the driving action of the motor 38, it will continuously push the arc-shaped plate 63, causing the arc-shaped plate 63 to drive the movable rod 62 to move. When the movable rod 62 moves, the movable plate 65 moves accordingly. An inclined surface is arranged on the movable plate 65. During the reciprocating movement of the movable plate 65, its inclined surface will continuously squeeze the sliding rod 33, causing the sliding rod 33 to continuously move upward. When the sliding rod 33 moves upward, a plurality of flapping plates 36 thereon will flap the screen mesh, and the screen mesh can be deformed when being flapped. In summary, the flapping action of the flapping plates 36 can directly and effectively make these particles fall off, avoiding the blockage of the screen mesh caused by the long-term residue of the particles, ensuring the smoothness of the pores of the screen mesh during subsequent screening, improving the use efficiency of the screen mesh, and reducing the production stagnation and cleaning cost caused by the blockage of the screen mesh.

[0054] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention by making equivalent substitutions or changes according to the technical solution of the present invention and its inventive concept.
