Description

TECHNICAL FIELD

[0001] The present application relates to the field of plastic recycling, and particularly relates to a plastic tray recycling processing equipment. BACKGROUND

[0002] Plastic trays are important appliances for assembling, stacking, carrying and transporting goods in the logistics and warehousing industry, which can effectively improve the efficiency of goods turnover. Since they are usually made of durable plastics such as high-density polyethylene or polypropylene, the production and waste are huge. In order to save resources, reduce environmental pollution and implement the concept of circular economy, it has become a necessary and economically beneficial industrial link to recycle a large number of waste and second-hand trays, which are crushed as recycled plastic raw materials.

[0003] The existing recycling work of waste trays usually starts with manual sorting and cleaning to remove metal impurities and other foreign matters. The core step thereafter is to crush them into uniform-sized pieces by a crushing device. These pieces are processed into recycled plastic particles that can be used for injection molding products after subsequent processes such as melting, filtering and granulation.

[0004] In the above crushing step, the common way is to directly and continuously convey the whole plastic tray to the upper side of a pair of crushing rollers by a conveyor, and let it fall freely. In this way, the falling point and posture of the tray are random and difficult to control accurately. When the tray does not fall vertically into the nip area between the two rollers, but the flat part of the tray falls on the roller surface of a single crushing roller first, a huge friction force will be generated between the high-speed rotating roller surface and the relatively stationary tray, causing the tray to slide, roll and even bounce on the roller surface, which cannot be "nipped" in time. This not only causes energy waste and abnormal wear of the roller surface, but also causes serious material accumulation and material jamming problems, forcing the production line to stop and clean, which seriously affects the continuity and efficiency of the recycling production.

[0005] Therefore, a plastic tray recycling processing equipment is proposed to solve the above problems. SUMMARY

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background.

[0007] The technical scheme adopted by the present application to solve its technical problems is: the plastic tray regeneration processing equipment comprises a climbing conveyor and a shell for feeding the plastic tray, the top of the shell is fixedly provided with a feeding port for collecting materials, and a pair of crushing rollers for crushing the plastic tray is rotatably arranged in the shell, a pair of inclined plates is symmetrically arranged, a pair of vertical plates is symmetrically fixed at the bottom of the inclined plate, and a plurality of guide rollers are rotatably arranged between the pair of vertical plates; the outer wall is provided with a sliding block between the pair of inclined plates and a first power source for driving the radial sliding of the sliding block; the sliding block and the inclined plate are rotatably connected through a connecting rod; through the cooperation of the inclined plate and the guide roller, the plastic tray can be limited by the guide rollers on both sides after entering the shell, so that the plastic tray can fall vertically between the pair of crushing rollers and be engaged by the crushing rollers, reducing the rebound and skidding of the traditional plastic tray directly falling on the surface of the crushing roller, and reducing the jamming of the plastic tray on the crushing roller due to skidding.

[0008] Preferably, the top of the feeding port is fixedly connected with a filling plate; the top of the filling plate is fixedly connected with a first guide plate with an opening facing the climbing conveyor; through the filling plate and the first guide plate, the falling point of the plastic tray on the feeding port can be controlled, the jamming of the plastic tray at the feeding port can be reduced, and the collection capacity of the feeding port for the plastic tray output by the climbing conveyor can be improved.

[0010] Preferably, the middle of the pressing rod is fixedly connected with a fixed plate; the inner wall of the inclined plate is fixedly connected with a limiting plate; in the initial state, the upper end face of the fixed plate is in close contact with the lower end face of the limiting plate, and at this time the first spring can be in a pre-tensioned state, which can forcibly limit the position of the end of the second arm before the plastic tray contacts the pressing plate, so as to reduce the jamming caused by the early contact of the plastic tray with the second arm to the greatest extent.

[0011] Preferably, the inside of the climbing conveyor is provided with a first crossbar, and the outer wall is provided with a second power source for driving the first crossbar to slide radially; the outer wall of the first crossbar is fixedly connected with second guide plates symmetrically distributed on both sides of the crushing roller; the plastic tray contacts different parts of the surface of the crushing roller every day, which can improve the utilization rate of the surface of the crushing roller, reduce the local wear of the crushing roller caused by the uneven contact surface of the traditional plastic tray and the crushing roller, and is worth mentioning that the outer diameter size of the second guide plate can be calibrated by the gap between the specific size of the plastic tray and the shell, so this place will not be expanded.

[0012] Preferably, the jacking assembly is a pair of settings, and the pressing plate and the second guide plate are located on the same axis; for example, a pair of pressing plates are located below the second guide plate, which can ensure that the plastic tray is first guided by the second guide plate and then contacted with the pressing plate after being located on one side of the predetermined crushing roller, so that the timing of the guiding of the second guide plate and the triggering of the pressing plate is more controllable.

[0013] Preferably, the outer wall of the guide roller is fixedly connected with a plurality of elastically arranged ratchets; a plurality of fixed rods are fixedly arranged on the inner wall of the shell; by arranging the ratchets, the inclined surface of the ratchet surface faces the bottom of the plastic tray during the sliding process of the plastic tray between the pair of vertical plates, that is, the resistance of the plastic tray during the sliding process of the plastic tray can be ignored, and the ratchet is elastically arranged, so that the plastic tray will not be blocked during the sliding process. When the plastic tray falls between the pair of crushing rollers, there will be a short moment of contact between the plastic tray and the inclined surface of the crushing roller, and during this process, the plastic tray will stop or slightly vibrate with the crushing roller. At this time, since the horizontal tooth surface of the ratchet faces the top of the plastic tray, the plastic tray will be subjected to a greater resistance to reduce the slight vibration of the plastic tray between the crushing rollers.

[0014] Preferably, the outer wall of the climbing conveyor is fixedly connected with a scale; the outer wall of the inclined plate is fixedly connected with a pointer in sliding cooperation with the scale; the operator can directly judge the gap size between the pair of vertical plates and the thickness of the plastic tray suitable for the pointer connected with the inclined plate.

[0016] Preferably, the second positioning plate is fixedly provided with a sliding rod in penetrating sliding connection with the climbing conveyor on one side; a pull rope is fixedly arranged between the sliding rod and the first positioning plate, and a second spring is fixedly arranged between the sliding rod and the climbing conveyor; when the operator adjusts the position of the first positioning plate by adjusting the screw rod, the first positioning plate can reduce the pulling force on the sliding rod through the pull rope, and the second positioning plate can slide along the climbing conveyor and approach the first positioning plate under the elastic restoring action of the pre-stretched second spring, so as to realize synchronous adjustment of the first positioning plate and the second positioning plate.

The plastic tray regeneration processing equipment disclosed by the present application can make the plastic tray receive the limiting action of the two guide rollers after entering the shell, thereby making the plastic tray fall vertically between a pair of crushing rollers and be engaged by the crushing rollers, reducing the rebound and skidding of the plastic tray when falling directly onto the surface of the crushing rollers, and reducing the jamming of the plastic tray at the crushing rollers due to skidding.

[0018] 2.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0023] The specific embodiments are given below.

[0024] Please refer to Figures 1 to 9As shown, the plastic tray regeneration processing equipment comprises a climbing conveyor 1 for feeding plastic trays and a shell 12, the top of the shell 12 is fixedly provided with a feeding port 19 for collecting materials, and a pair of crushing rollers 13 for crushing plastic trays is rotatably arranged inside the shell 12, a pair of inclined plates 14 is symmetrically slidably arranged, a pair of vertical plates 15 is symmetrically fixedly arranged at the bottom of the inclined plate 14, and a plurality of guide rollers 16 is rotatably arranged between the pair of vertical plates 15; and the outer wall is provided with a sliding block 17 located between the pair of inclined plates 14 and a first power source for driving the radial sliding of the sliding block 17; the sliding block 17 and the inclined plate 14 are rotatably connected through a connecting rod 18; When working, the plastic trays can be manually or by a conveyor fed onto the climbing conveyor 1, and the feeding direction of the plastic trays should be as shown in the figure Figure 1 As shown, the smooth surface is located below, and the supporting legs are located above. After the climbing conveyor 1 is started, the plastic trays can be transported to the top of the shell 12 at a high slope, so that the plastic trays can enter the inside of the shell 12 through the feeding port 19 and be directly extruded and broken by the pair of mutually counter-rotating crushing rollers 13. The broken fragments can fall to another conveyor (not shown in the figure) through the bottom of the shell 12 and be transported to a cleaning sink; The specific process that the above plastic trays enter the inside of the shell 12 and are directly extruded and broken by the crushing rollers 13 is as follows: the plastic trays slide to the surface of the inclined plate 14 through the feeding port 19, and then the plastic trays can directly fall between the pair of vertical plates 15 under the action of the self-weight of the inclined surface. The center line of the pair of vertical plates 15 and the center line of the pair of crushing rollers 13 coincide in the vertical projection. During the falling process, the guide rollers 16 on the vertical plates 15 can make the plastic trays receive a transverse constraint action and a minimum descending resistance, so that the plastic trays can directly fall between the pair of crushing rollers 13 and be engaged by the crushing rollers 13. In addition, for plastic trays of different thicknesses, the staff can start the first power source, preferably an electric cylinder, to drive the vertical movement of the sliding block 17, so as to adjust the gap between the pair of vertical plates 15. Figure 4 For example, when the sliding block 17 moves downward, the pair of connecting rods 18 on both sides can be deflected, and then the connecting rods 18 can pull the inclined plate 14 and the vertical plate 15 directly connected thereto to move closer to each other, so as to adjust the gap between the pair of vertical plates 15. Through the cooperation of the inclined plate 14 and the guide roller 16, the plastic trays can receive the limiting action of the guide rollers 16 on both sides after entering the inside of the shell 12, so that the plastic trays can fall vertically between the pair of crushing rollers 13 and be engaged by the crushing rollers 13, reducing the rebound and skidding of the traditional plastic trays directly falling onto the surface of the crushing rollers 13 and reducing the jamming of the plastic trays at the crushing rollers 13 due to skidding.

[0025] As shown in Figure 2 and Figure 3 As shown, the top of the filling plate 2 is fixedly connected with a first guide plate 22 with an opening facing the climbing conveyor 1; As shown, the top of the filling plate 2 is fixedly connected with a first guide plate 22 with an opening facing the climbing conveyor 1;Figure 3 For example, filling the filling plate 2 away from the side of the feeding port 19 of the inclined conveyor 1 can control the landing point of the plastic tray on the crushing roller 13, avoid the lower end of the plastic tray landing on the side away from the inclined conveyor 1 of the feeding port 19 (i.e. the filling position of the filling plate 2) to cause the material blocking on the feeding port 19, and make the opening of the first guide plate 22 face the end of the inclined conveyor 1, so that the plastic tray conveyed by the inclined conveyor 1 can directly pass through the first guide plate 22 and fall into the inside of the feeding port 19, thereby improving the collection capacity of the feeding port 19 for the plastic tray. Through the filling plate 2 and the first guide plate 22, the landing point of the plastic tray on the feeding port 19 can be controlled, the material blocking of the plastic tray on the feeding port 19 can be reduced, and the collection capacity of the feeding port 19 for the plastic tray output by the inclined conveyor 1 can be improved.

[0026] Please refer to Figures 4 to 8 As shown in the figure, the inclined plate 14 is provided with a jacking assembly for jacking the plastic tray; the jacking assembly comprises a pressing rod 32 which is slidably arranged in the inside of the inclined plate 14; one end of the pressing rod 32 is fixedly connected with a pressing plate 3, the other end is fixedly provided with a first spring 35 between the outer wall of the inclined plate 14, and the other end is rotatably provided with a first branch arm 33; the end of the first branch arm 33 is slidably provided with a second branch arm 34 which is rotatably arranged at the bottom of the crushing roller 13; Since the feeding port 19 and the inclined plate 14 are inclinedly arranged, and the vertical plate 15 is vertically arranged, that is, the plastic tray needs to be directly and harshly adjusted from the inclined state on the inclined plate 14 to the vertical state between the vertical plates 15, if the horizontal momentum of the plastic tray sliding under the inclined plate 14 is large, it is difficult to complete the switching of the state conversion from the inclined state to the vertical state, so there is a risk of material blocking of the plastic tray at the connection between the inclined plate 14 and the vertical plate 15; In the initial state, the first spring 35 is in the normal state, and the end of the second branch arm 34 will not exceed the end face of the feeding port 19 (such as Figure 8 As shown in the figure, the end of the second branch arm 34 is flush with the feeding port 19), so as to avoid the second branch arm 34 from hindering the sliding of the plastic tray, and the plastic tray will successively slide along the surface of the feeding port 19 and the inclined plate 14 after entering the inside of the feeding port 19, when the lower end of the plastic tray slides on the inclined plate 14, it will contact the pressing plate 3, since the pressing plate 3 is provided with a spherical surface, the pressing plate 3 can slide into the inside of the inclined plate 14 under the extrusion of the plastic tray, so as to Figure 8For example, the pressing plate 3 and the pressing rod 32 will move downward and make the first spring 35 in a stretched state, and the pressing rod 32 can push the directly connected first arm 33 and the second arm 34 to deflect when the pressing rod 32 moves downward, and because the force arm of the first arm 33 is shorter than that of the second arm 34, under the amplification effect of the lever, the downward movement of the pressing rod 32 and the first arm 33 can make the second arm 34 still exert extrusion on the upper end of the plastic tray at the inlet 19 during the deflection process, so that the upper end of the plastic tray is deflected to the inner wall of the filling plate 2, and also makes the plastic tray in a more vertical posture before entering the pair of vertical plates 15, so as to facilitate the smooth entry of the plastic tray between the pair of vertical plates 15, and further reduce the jamming of the plastic tray at the connection between the inclined plate 14 and the filling plate 2.

[0027] As shown in Figure 7 and Figure 8 , the middle part of the pressing rod 32 is fixedly connected with a fixed plate 4; the inner wall of the inclined plate 14 is fixedly connected with a limiting plate 42; As shown in Figure 8 , the upper end surface of the fixed plate 4 is in close contact with the lower end surface of the limiting plate 42, and at this time the first spring 35 can be in a pre-stretched state, and such arrangement can forcibly limit the position of the end of the second arm 34 before the plastic tray contacts the pressing plate 3, so as to reduce the jamming caused by the early contact of the plastic tray with the second arm 34 to the greatest extent.

[0028] As shown in Figures 6 to 8 , the inside of the climbing conveyor 1 is provided with a first cross rod 5, and the outer wall is provided with a second power source for driving the first cross rod 5 to slide radially; the outer wall of the first cross rod 5 is fixedly connected with a pair of second guide plates 52 symmetrically distributed on both sides of the crushing roller 13; In actual use of the device, for example, daily work, the staff can start the second power source before starting the device each time, preferably a cylinder, so that the piston can drive the first cross rod 5 and a pair of second guide plates 52 on the first cross rod 5 to move radially, so as to Figure 6 For example, at this time the cylinder is in a contracted state, and the second guide plate 52 located on the left side is on the surface of the inlet 19, and when the plastic tray slides to the surface of the inlet 19, it can slide to one side of the second guide plate 52 under the arc surface guiding effect of the second guide plate 52, and the next day the right second guide plate 52 can be driven to slide to the surface of the inlet 19 by starting the cylinder, so that the plastic tray can slide to the other side, and such arrangement can make the plastic tray contact different parts of the surface of the crushing roller 13 every day, which can improve the utilization rate of the surface of the crushing roller 13, so as to reduce the local wear of the crushing roller 13 caused by the uneven contact of the traditional plastic tray with the surface of the crushing roller 13, and it is worth mentioning that the outer diameter size of the second guide plate 52 can be calibrated by the gap between the specific size of the plastic tray and the outer shell 12, so it is not expanded here.

[0029] As shown in Figure 6As shown, the lifting components are arranged in pairs, and the pressure plate 3 and the second guide plate 52 are located on the same axis; by Figure 6 For example, both pressure plates 3 are located below the second guide plate 52. This arrangement ensures that the plastic tray is first guided by the second guide plate 52 to one side of the predetermined crushing roller 13 before contacting the pressure plate 3, making the timing of the two actions of guiding the second guide plate 52 and triggering the pressing down of the pressure plate 3 more controllable.

[0030] Please see Figures 2 to 5 As shown, the outer wall of the guide roller 16 is fixed with a plurality of elastically arranged ratchet teeth 7; the inner wall of the outer shell 12 is fixed with a plurality of fixing rods 72. By setting ratchet 7 and fixing rod 72, during the process of the plastic pallet sliding down between a pair of upright plates 15, Figure 5 For example, the plastic pallet falls from the left side of the guide roller 16. The smooth tooth back of the ratchet 7 faces the bottom of the plastic pallet, and the inclined tooth surface faces the fixed rod 72. That is, the guide roller 16 can rotate counterclockwise during the downward movement of the plastic pallet. At this time, the resistance between the ratchet 7 and the fixed rod 72 is negligible. The ratchet 7 is elastically designed and can be made of wear-resistant, highly elastic polyurethane or rubber material to provide effective resistance while avoiding scratching the surface of the plastic pallet. The plastic pallet will not jam during the downward movement. When the plastic pallet falls between a pair of crushing rollers 13, there will be a brief moment of contact between the plastic pallet and the inclined surface of the crushing roller 13. During this process, the plastic pallet will stop or come into contact with the powder. Slight jumping occurs between the crushing rollers 13, which causes the guide roller 16 to rotate in the opposite direction (clockwise). Since the horizontal tooth surface of the ratchet 7 faces the fixing rod 72 and generates a large frictional resistance, the guide roller 16 and the plastic tray will be subjected to a large resistance to reduce the slight jumping between the plastic tray and the crushing rollers 13. It is worth mentioning that the ratchet 7 can be installed on the guide roller 16 by pressing the T-shaped or dovetail-shaped anchoring structure at the base of the ratchet 7 into the groove with a matching shape on the surface of the guide roller 16 to achieve the matching fixation of the ratchet 7. The groove can be coated with a high-strength adhesive. This fixing method can effectively resist the tangential force on the ratchet 7 when the plastic tray slides down and prevent it from falling off.

[0031] Please see Figure 1 and Figure 5 As shown, a scale 8 is fixedly connected to the outer wall of the inclined conveyor 1; a pointer 82 that slides with the scale 8 is fixedly connected to the outer wall of the inclined plate 14. Operators can visually determine the gap between a pair of uprights 15 and the thickness of the matching plastic pallet by observing the scale reading on the ruler 8 indicated by the pointer 82, which is directly connected to the inclined plate 14.

[0032] Please see Figure 1 and Figure 9As shown, the outer wall of the climbing conveyor 1 is symmetrically provided with a V-shaped first positioning plate 9 and a second positioning plate 94; the first positioning plate 9 is rotatably provided with a screw rod 92 in threaded connection with the climbing conveyor 1, and is fixedly provided with a second cross rod 93 in penetrating sliding connection with the climbing conveyor 1; Before the device works, the operator can control the screw rod 92 to slide horizontally along the climbing conveyor 1 by rotating the screw rod 92, thereby controlling the gap size between the first positioning plate 9 and the second positioning plate 94; the second cross rod 93 can provide a limiting action for the first positioning plate 9, and through the V-shaped structure of the first positioning plate 9 and the second positioning plate 94, the plastic tray at the end of the climbing conveyor 1 is forced to be centered, thereby making the posture of the plastic tray controllable when entering the shell 12, and facilitating the stable movement in the shell 12.

[0033] Please refer to Figure 9 As shown, the second positioning plate 94 is fixedly provided with a sliding rod 1001 in penetrating sliding connection with the climbing conveyor 1 on one side; the sliding rod 1001 and the first positioning plate 9 are fixedly provided with a pull rope 1000, and the climbing conveyor 1 is fixedly provided with a second spring 1002; Through the cooperation of the sliding rod 1001 and the second spring 1002, when the operator adjusts the screw rod 92 to control the position of the first positioning plate 9, the first positioning plate 9 can reduce the pulling force on the sliding rod 1001 through the pull rope 1000, and the second positioning plate 94 can slide along the climbing conveyor 1 and approach the first positioning plate 9 under the elastic reset action of the pre-stretched second spring 1002, so as to realize the synchronous adjustment of the first positioning plate 9 and the second positioning plate 94.

It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
