Description

Technical Field

[0001] The present invention relates to the technical field related to the processing of plastic products, and specifically to a pre-treatment device for processing plastic spoons. Background Art

[0002] Plastic spoons are a common type of tableware, usually used for packaging takeaway food tableware. Compared with customers using their own tableware, this disposable plastic spoon avoids the risk of cross-contamination. Common plastics used to make plastic spoons include polypropylene, polystyrene, and polycarbonate, etc. During the processing, due to electrostatic or self-adhesion on the plastic particles, a certain amount of powder will inevitably adhere. Therefore, during the pre-treatment process of plastic particles, powder removal treatment needs to be carried out on the plastic particles.

[0003] Currently, existing pre-treatment devices will use the method of air separation to carry out powder removal treatment on plastic particles, and will set up a striking mechanism to separate the plastic particles from the powder. However, even after the plastic particles are struck, the plastic particles will still fall in a piled-up state. And the air flow is not easy to penetrate between the piled-up plastic particles, which will result in the air flow not being able to remove the powder well, leading to incomplete powder removal. Secondly, since usually various different types of plastic particles are mixed and then powder removal is carried out during air separation, the physical properties such as size, shape, and density of different types of plastic particles vary greatly. Some lighter and smaller plastic particles are easily disturbed by the air flow during air separation, resulting in stratification of different types of plastic particles, thereby affecting the mixing uniformity of various plastic particles. Summary of the Invention

[0004] The purpose of the present invention is to provide a pre-treatment device for processing plastic spoons, so as to solve the problems in the above-mentioned background art that existing pre-treatment devices use the method of air separation to carry out powder removal treatment on plastic particles, and will set up a striking mechanism to separate the plastic particles from the powder. However, even after the plastic particles are struck, the plastic particles will still fall in a piled-up state, and the air flow is not easy to penetrate between the piled-up plastic particles. Secondly, different types of plastic particles during air separation are easily disturbed by the air flow, resulting in stratification.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A pre-treatment device for processing plastic spoons, including a main body, An air separation chamber is opened inside the main body, and a stirring box is fixed on the top of the main body. The stirring box is communicated with the air separation chamber through a feeding pipe, and a discharge gate one is arranged inside the feeding pipe. One end of the inner wall of the air separation chamber is provided with a blower, and a slag discharge channel is opened at the other end of the inner wall of the air separation chamber. A dust collector is arranged outside the slag discharge channel. A rotating rod is horizontally arranged inside the air separation chamber, and a stirring mechanism one is arranged inside the stirring box; A rotating shaft is arranged inside the main body. One end of the rotating shaft is connected to a rotating rod. A number of sets of dispersing plates are fixed on the rotating rod, and a dispersing plate is arranged below the rotating rod. A driving mechanism is also arranged inside the main body, and the driving mechanism is used to drive the dispersing plate to move horizontally back and forth. A conveying channel is opened inside the main body. The upper and lower ends of the conveying channel are respectively communicated with the air separation bin through a feeding channel and a discharging channel. A guiding gate one is arranged inside the discharging channel. A conveying mechanism is arranged inside the conveying channel. A storage bin is opened inside the main body, and the top of the storage bin is communicated with the conveying channel through a guiding gate two.

[0006] In the above technical solution, the rotating shaft drives the rotating rod and the dispersing plates to rotate. When feeding the plastic particles, the rotation of the rotating rod can drive the dispersing plates to strike the falling plastic particles, destroying the adsorption or entrainment state of the powder on the surface of the plastic particles, so that the powder firmly adhered to the plastic particles can be separated, improving the powder removal effect on the plastic particles. After the plastic particles are struck, the pores on the dispersing plate will slow down the falling speed of the plastic particles, preventing a large number of plastic particles from falling together, so that the powder in the plastic particles can be more easily carried away by the air flow. And the driving mechanism can drive the dispersing plate to move horizontally back and forth. On the one hand, it can make the plastic particles disperse and fall evenly, and on the other hand, it can also prevent the plastic particles from accumulating on the dispersing plate and causing the pores on the dispersing plate to be blocked.

[0007] Preferably, a motor one is arranged on the outer side of the main body, and the output end of the motor one is connected to the rotating shaft.

[0008] In the above technical solution, the motor one can drive the rotating shaft to rotate, and the rotating shaft can drive the rotating rod and the dispersing plates to rotate, so that the dispersing plates strike the plastic particles, and thus it is easier to separate the powder entrained on the plastic particles.

[0009] Preferably, the stirring mechanism one includes a motor two. The motor two is installed on the top of the outer side of the stirring box. A stirring shaft one is installed on the top of the inner side of the stirring box. The stirring shaft one is connected to the output end of the motor two, and a number of sets of stirring rods are fixed on the stirring shaft one.

[0010] In the above technical solution, before removing the powder from the plastic particles, various types of plastic particles can be centrally placed in the stirring box, and then the motor two drives the stirring shaft one and the stirring rods to rotate to mix and process the various plastic particles.

[0011] Preferably, a movable plate is fixed on the side of the dispersing plate. A fixed rod is fixed inside the air separation bin, and the fixed rod passes through the movable plate and is slidably connected to it.

[0012] In the above technical solution, the movable plate can slide on the fixed rod, and the fixed rod can guide the lateral movement of the movable plate.

[0013] Preferably, the driving mechanism includes a first bevel gear installed inside the main body. A second bevel gear is fixed on the rotating shaft, and the second bevel gear meshes with the first bevel gear. A turntable is provided at the bottom of the first bevel gear, and an eccentric column is installed at the bottom of the turntable. A chute is formed on the movable plate, and the eccentric column is located in the chute.

[0014] In the above technical solution, when the first motor drives the rotating shaft to rotate, when the rotating shaft drives the rotating rod and the dispersing plate to rotate, the rotating shaft will also drive the second bevel gear to rotate at the same time. The second bevel gear will drive the meshing first bevel gear to rotate and drive the turntable to rotate. When the turntable rotates, it will drive the eccentric column to rotate around the central axis of the turntable. At the same time, the eccentric column will move in the chute on the movable plate, thereby driving the movable plate and the dispersing plate to perform horizontal reciprocating motion. This technical solution can drive the rotation of the dispersing plate and the horizontal reciprocating motion of the dispersing plate simultaneously through the first motor, reducing the setting of the driving source and further reducing the production cost.

[0015] Preferably, the conveying mechanism includes a fourth motor fixed on the top of the main body, and the output end of the fourth motor is connected to the conveying auger, and the conveying auger is vertically installed in the conveying channel.

[0016] In the above technical solution, after the plastic particles are separated by air selection to remove powder, to avoid incomplete powder removal, the fourth motor can be used to drive the conveying auger to rotate, so as to convey the plastic particles, so as to convey the air-selected plastic particles below the air selection bin upward, so that the plastic particles are circulated for air selection.

[0017] Preferably, the second stirring mechanism includes a fifth motor fixed on the top of the main body, and the output end of the fifth motor is connected to the second stirring shaft. The second stirring shaft is installed inside the storage bin, and a number of groups of stirring rods are fixed on the second stirring shaft.

[0018] In the above technical solution, when the conveying mechanism conveys the plastic particles, if the first material guiding gate is opened and the second material guiding gate is closed, the plastic particles will be discharged from the discharge channel. If the first material guiding gate is closed and the second material guiding gate is opened, the plastic particles will be conveyed to the storage bin for storage. To avoid stratification of different types of plastic particles after air selection and powder removal, after the plastic particles enter the storage bin, the fifth motor can be used to drive the second stirring shaft and the stirring rods to rotate, so as to perform secondary stirring on the powder-removed plastic particles, avoid affecting the mixing uniformity of the plastic particles in the later stage of powder removal, and facilitate subsequent injection molding and melting of the plastic particles.

[0019] Preferably, a second discharge gate is provided at the bottom of the storage bin, and a conveyor belt is provided below the second discharge gate.

[0020] In the above technical solution, after the second discharge gate is opened, the plastic particles in the storage bin will fall onto the conveyor belt, and then the plastic particles can be conveyed to the next processing point for processing through the conveyor belt, eliminating the need for manual handling and improving production efficiency.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: for this plastic spoon processing pretreatment device, 1. The falling plastic particles are struck by the striking plate to break the adsorption or entrainment state of the powder on the surface of the plastic particles. After the plastic particles are struck, the pores on the dispersion plate will slow down the falling speed of the plastic particles, preventing a large number of plastic particles from falling together. This enables the powder in the plastic particles to be more easily carried away by the air flow. Moreover, the drive mechanism can drive the dispersion plate to move horizontally back and forth. On the one hand, it can evenly disperse the plastic particles during falling to improve the powder removal effect; on the other hand, it can also prevent the plastic particles from accumulating on the dispersion plate and blocking the pores. This technical solution can not only strike the plastic particles to separate the powder but also prevent the plastic particles from falling together, making it easier for the air flow to penetrate the plastic particles for powder removal, and the powder removal effect is better; 2. After the plastic particles are subjected to air separation for powder removal, to avoid incomplete powder removal, the plastic particles can be conveyed through the conveying mechanism in the conveying channel. The plastic particles enter from the feeding channel and then are discharged from the discharging channel, thereby realizing cyclic air separation of the plastic particles without the need to frequently stop the machine for loading and unloading materials. This continuous operation mode greatly improves the powder removal effect and efficiency of the plastic particles; 3. After the plastic particles are conveyed to the storage bin for storage, to prevent different types of plastic particles from stratifying after air separation for powder removal, after the plastic particles enter the storage bin, the motor five can drive the stirring shaft two and the stirring rods to rotate to secondarily stir the powder-removed plastic particles, preventing the plastic particles from affecting the mixing uniformity after powder removal and facilitating subsequent injection molding and melting of the plastic particles. After the second discharge gate is opened, the plastic particles in the storage bin will fall onto the conveyor belt, and then the plastic particles can be conveyed to the next processing point for processing through the conveyor belt, eliminating the need for manual handling and improving production efficiency.

One end of the rotating shaft 12 is connected to the rotating rod 10. A number of sets of dispersing plates 13 are fixed on the rotating rod 10. And below the rotating rod 10, a dispersing plate 14 is provided. Inside the main body 1, a driving mechanism 17 is also provided. The driving mechanism 17 is used to drive the dispersing plate 14 to move horizontally back and forth. A conveying channel 21 is opened inside the main body 1. And the upper and lower ends of the conveying channel 21 are respectively communicated with the air separation bin 2 through a feeding channel 22 and a discharging channel 23. A guiding gate one 24 is arranged inside the discharging channel 23. A conveying mechanism 25 is arranged inside the conveying channel 21. A storage bin 26 is opened inside the main body 1. And the top of the storage bin 26 is communicated with the conveying channel 21 through a guiding gate two 27. A stirring mechanism two 28 is arranged in the storage bin 26.

[0026] Furthermore, a filter screen 18 is arranged inside the slag discharging channel 8. And a screen mesh 19 is fixed at one end inside the slag discharging channel 8. A cleaning mechanism 20 is arranged inside the slag discharging channel 8.

[0027] The cleaning mechanism 20 includes a lead screw 2001. The lead screw 2001 is installed at one end inside the slag discharging channel 8.

[0031] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a movable plate 15 is fixed on the side of the dispersion plate 14, a fixed rod 16 is fixed inside the air separation bin 2, and the fixed rod 16 passes through the movable plate 15 and is slidably connected to it.

[0032] As Figure 1 and Figure 2 shown, the driving mechanism 17 includes a first bevel gear 1701. The first bevel gear 1701 is installed inside the main body 1. A second bevel gear 1702 is fixed on the rotating shaft 12, and the second bevel gear 1702 meshes with the first bevel gear 1701. A turntable 1703 is arranged at the bottom of the first bevel gear 1701, and an eccentric column 1704 is installed at the bottom of the turntable 1703.

[0033] As Figure 1 shown, the conveying mechanism 25 includes a fourth motor 2501. The fourth motor 2501 is fixed on the top of the main body 1, and the output end of the fourth motor 2501 is connected to the conveying auger 2502.

[0035] As Figure 1 shown, a second discharge gate 29 is arranged at the bottom of the storage bin 26, and a conveyor belt 30 is arranged below the second discharge gate 29.

[0036] Working principle: When in use, first pour various different types of plastic particles to be mixed into the mixing box 3. Then turn on the second motor 1101 to drive the first stirring shaft 1102 and the stirring rod 1103 to rotate, so as to stir and mix the various plastic particles. After the mixing is completed, first turn on the fan 7 and the dust collector 9. Then turn on the first motor 6 to drive the rotating shaft 12, the rotating rod 10 and the dispersing plate 13 to rotate. When the rotating shaft 12 rotates, it will drive the second bevel gear 1702 to rotate at the same time. The second bevel gear 1702 will drive the first bevel gear 1701 and the turntable 1703 to rotate. When the turntable 1703 rotates, it will drive the eccentric column 1704 to rotate around the central axis of the turntable 1703. At the same time, the eccentric column 1704 will move in the chute 1705 on the movable plate 15, so as to drive the movable plate 15 and the dispersing plate 14 to perform horizontal reciprocating motion. Then open the first discharge gate 5 to pour the plastic particles in the mixing box 3 into the air separation bin 2. After the plastic particles enter the air separation bin 2, first the dispersing plate 13 will strike the plastic particles to separate the powder wrapped on the plastic particles. Then the plastic particles will fall onto the dispersing plate 14. The dispersing plate 14 can prevent the plastic from falling together. Along with the shaking effect generated by the horizontal reciprocating motion of the dispersing plate 14, the plastic particles can be evenly dispersed and fall, making it easier for the air flow to blow off the powder. After the powder is blown off, it will follow the air flow into the slag discharge channel 8 for collection, while the plastic particles will fall to the bottom of the air separation bin 2. To improve the powder removal effect, the first guide gate 24 can be opened and the second guide gate 27 can be closed. Then turn on the fourth motor 2501 to drive the conveying auger 2502 to rotate. The conveying auger 2502 will enter the plastic particles from the feeding channel 22 and discharge them from the discharging channel 23, so as to perform cyclic air separation and powder removal on the plastic particles. When the powder removal of the plastic particles is completed, the second guide gate 27 can be opened and the first guide gate 24 can be closed. Then turn on the fourth motor 2501 again to drive the conveying auger 2502 to rotate. At this time, the conveying auger 2502 will convey the plastic particles to the storage bin 26 for storage. To avoid stratification of different types of plastic particles after air separation and powder removal, after the plastic particles enter the storage bin 26, the fifth motor 2801 can be used to drive the second stirring shaft 2802 and the stirring rod 2803 to rotate, so as to perform secondary stirring on the powder-removed plastic particles, ensuring the mixing degree of the powder-removed plastic particles. Then the second discharge gate 29 can be opened to discharge the plastic particles in the storage bin 26 onto the conveyor belt 30, and the conveyor belt 30 will convey the plastic particles to the next processing point for processing.
