Description

Technical Field

[0001] The invention relates to the field of plastic production, in particular to a high-efficiency raw material cleaning device used in plastic production. Background Art

[0002] Plastic raw materials are mostly tiny particles, which are in contact with the outside for a long time during the production process. In addition, the sum of the surface areas of a large number of small-volume plastic particles is very large, which means that the contact area between the plastic particles and the air is very large. This causes the surface of the plastic particles to be covered with a lot of dust, so they need to be cleaned before plastic production begins.

[0003] The cleaning of plastics often requires two processes, namely cleaning and dehydration. There are two existing modes. One is that the cleaning and dehydration work are carried out in two separate devices, and the other is that the cleaning and dehydration are completed in the same device. Both have their advantages and disadvantages.

[0004] The cleaning and dehydration machines are often slow in cleaning speed. Since the dehydration device needs to rotate at high speed, there must be no stirring rod in the cleaning chamber. Otherwise, the collision between the stirring rod and the plastic particles during the dehydration process will cause damage to the equipment and reduce the service life of the equipment. If the cleaning and dehydration are carried out separately, the cleaning time will be greatly increased, and unnecessary raw material loss will also be caused during the transfer process.

[0005] At the same time, multiple motors often work together during the cleaning process, and different motors provide power for different working stages. This is more dependent on the operator's proficiency or program design and has a certain degree of uncontrollability.

[0006] All of the above reasons have resulted in the current plastic raw material cleaning being slow, requiring professional personnel to operate, and being costly.

[0007] Based on this, the present invention designs a high-efficiency raw material cleaning device for plastic production to solve the above problems. Summary of the invention

[0008] The purpose of the present invention is to provide a high-efficiency cleaning device for raw materials in plastic production, so as to solve the problems raised in the above-mentioned background technology: the cleaning and dehydration integrated machine often has a slow cleaning speed. Since the device needs to rotate at high speed during the dehydration process, there must be no stirring rod in the cleaning chamber, otherwise the collision between the stirring rod and plastic particles during the dehydration process will cause damage to the equipment and reduce the service life of the equipment; and cleaning and dehydration are carried out separately, which will greatly increase the cleaning time and cause unnecessary raw material loss during the transfer process; at the same time, multiple motors often work together during the cleaning process, and different motors are used to provide power for different working stages, which is more dependent on the operator's proficiency or the design of the program and has a certain degree of uncontrollability; the cleaning of plastic raw materials is slow and requires professional operation, which is costly.

A sewage and plastic outlet is also provided at the bottom of the fixing device. The top output end of the power motor is fixedly connected to an internal rotating shaft, and an outer shaft is sleeved on the outer side of the internal rotating shaft. The outer shaft and the internal rotating shaft rotate synchronously due to the internal groove structure and can be raised and lowered a short distance. Through this design, the same motor can provide power for cleaning and dehydration at different time periods;

[0012] Preferably, the stirring device includes a fixed plate A, which is fixedly connected to the inner wall of the cleaning cavity through a connecting plate, and the fixed plate A is located in the middle of the cleaning sphere, and the fixed plate A provides fixation for the cleaning shaft, and the bottom of the fixed plate A is rotatably connected to the cleaning shaft through a bearing, and the cleaning shaft sleeve is arranged on the outside of the outer shaft, and three groups of stirring rods are arranged on the outside of the stirring device, and the three groups of stirring rods cover most of the space of the cleaning cavity to ensure that the plastic is fully stirred;

The filter screen is removed when the plastic needs to flow out, otherwise the filter screen is installed.

[0016] Preferably, both ends of the outer shaft are connected to a pressure plate, which is part of the spherical surface and has a groove facing the inside of the cleaning sphere. When the cleaning sphere is flipped, water will also flow. At this time, the pressure plate below will move downward under the action of the water flow, driving the outer shaft to move. When flipped again, the outer shaft will move in the opposite direction, thereby realizing the conversion between the cleaning mode and the dehydration mode.

[0017] Preferably, a group in the middle of the stirring rod is connected to the cleaning shaft through a connecting protective shell, and a fixing plate B is fixedly connected to the middle part of the rotating drum, and the fixing plate B is sleeved on the outside of the outer shaft. The interior of the fixing plate B and the connecting protective shell are both provided with hollow cavities and the inner walls are both provided with slots. Two lifting clips are fixedly provided on the outside of the outer shaft, and the two lifting clips are respectively located inside the fixing plate B and the connecting protective shell.

[0019] Preferably, the flipping assembly also includes a protective shell, and the telescopic block, spring A, bevel gear A and bevel gear B are all arranged inside the protective shell. The bottom of the protective shell is provided with a groove for facilitating the movement of the lifting block. The bottom of the telescopic block is provided with an inclined groove, and the inclination angle of the bottom of the inclined groove is the same as the inclination angle of the top of the lifting block.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention separates the cleaning and dehydration spaces by setting two chambers in one sphere, so that the two do not interfere with each other and are more efficient when working separately. By flipping the sphere, the working mode can be quickly switched without using two machines to work separately, thereby improving work efficiency.

[0024] 2. The present invention utilizes the flow of water when the cleaning ball is flipped and the effect of gravity to automatically switch between the cleaning mode and the dehydration mode. When the cleaning cavity is flipped to the bottom, it automatically cleans, and when the dehydration cavity is flipped to the bottom, it automatically dehydrates. The whole process is automated with a low failure rate. There will be no mechanical damage due to human operating errors, and work efficiency is also improved.

[0025] 3. In the present invention, since the rotation of the telescopic rod is affected by the output power of the power motor, and the cleaning and dehydration work are also affected by the output power of the power motor, the mode switching time will change with the change of the output power of the power motor. The higher the output power of the power motor, the faster the cleaning and dehydration work, and the faster the mode switching speed, and vice versa. In this way, it can be ensured that the plastic is fully cleaned and will not be affected by the working voltage.

[0026] In summary, the present invention integrates a cleaning component and a dehydration component in the same device, and realizes mode switching through a flip component, which is controlled by an automatic control component, thereby ensuring that the operation of each component will not affect each other during mode switching. In addition, the present invention ensures that the cleaning device modes will not work at the same time through the linkage of the mechanical structure at the beginning of the design, thereby preventing waste of resources, and also improving the work efficiency when working in a single mode. No manual operation is required throughout the process, thereby reducing the time waste of manual operation and equipment loss caused by possible operational errors.

[0040] See also Figure 1-9 The present invention provides a technical solution: a high-efficiency cleaning device for raw materials used in plastic production, comprising a fixing device 1, a hemispherical groove is provided at the top center of the fixing device 1, and a cleaning ball 2 is arranged in the groove, the horizontal center axis of the cleaning ball 2 is connected to the fixing device 1 through a connecting rod and a bearing, the internal cavity of the cleaning ball 2 is divided into an upper and lower part, namely a cleaning cavity below and a dehydration cavity above, a power component 3 and a stirring device 4 are arranged in the cleaning cavity, a dehydration component 7 is arranged in the dehydration cavity, and an automatic control component 6 for controlling the flipping of the cleaning ball 2 and a flip component 5 for supporting are arranged at the connection between the cleaning cavity and the dehydration cavity;

[0041] The power assembly 3 includes a power motor 301, which is threadedly mounted on the bottom of the cleaning ball 2. An arc-shaped groove 101 is provided on the inner side of the fixing device 1 to facilitate the movement of the power motor 301. The top output end of the power motor 301 is fixedly connected with an internal shaft 302. The outer side of the internal shaft 302 is sleeved with an outer shaft 303. The outer shaft 303 and the internal shaft 302 rotate synchronously due to the internal groove structure and can be raised and lowered a short distance.

[0042] The stirring device 4 includes a fixed plate A401, which is fixedly connected to the inner wall of the cleaning cavity through a connecting plate, and the fixed plate A401 is located in the middle of the cleaning sphere 2. The bottom of the fixed plate A401 is rotatably connected to a cleaning shaft 402 through a bearing, and the cleaning shaft 402 is sleeved on the outside of the outer shaft 303. Three groups of stirring rods 403 are arranged on the outside of the stirring device 4;

[0043] The flip assembly 5 includes a flip shaft 501, which is located on the same straight line as the connecting rod connecting the cleaning ball 2 and the fixing device 1. One end of the flip shaft 501 close to the center of the cleaning ball 2 is telescopically connected to a telescopic block 502 through a spring A503, and the other end of the telescopic block 502 is connected to a bevel gear A505. The flip assembly 5 also includes a bevel gear B506, which is fixedly sleeved on the outside of the outer shaft 303. When the telescopic block 502 is extended, the bevel gear A505 is meshed with the bevel gear B506 for transmission.

[0044] The automatic control component 6 includes an arc-shaped raised plate 601 and a slow-speed gear set. Two arc-shaped raised plates 601 are provided and fixedly mounted on the inner wall of the cleaning chamber. The two arc-shaped raised plates 601 are centrally symmetrically distributed and the connecting line between the two is perpendicular to the flip axis 501. The slow-speed gear set is mounted on the top of the fixed plate A401. The top of the slow-speed gear set is connected to a rotating plate 602. The rotating plate 602 and the arc-shaped raised plate 601 are located on the same horizontal line. The outer side of the rotating plate 602 is connected to a telescopic rod.

[0045] The dehydration assembly 7 includes a drum 701, the surface of which is penetrated with tiny water leakage holes. The drum 701 maintains a certain distance from the dehydration cavity. The outer side of the drum 701 is connected to the dehydration cavity through a large bearing. The cleaning ball 2 is located at the top of the dehydration cavity and is provided with an inlet and outlet 201.

[0046] First embodiment: Figure 2 As shown, after the plastic and clean water enter the cleaning ball 2 from the inlet and outlet 201, they flow into the cleaning cavity. The plastic and clean water cannot overflow the cleaning cavity. At this time, the power motor 301 is started, and the stirring device 4 starts to operate. The internal rotating shaft 302 drives the outer shaft 303 and then drives the cleaning shaft 402 to rotate, so that the stirring rod 403 rotates to stir the plastic particles and clean the plastic particles.

[0047] After a period of cleaning, the flip assembly 5 starts to work, flips the cleaning ball 2 180 degrees, and the dehydration cavity rotates to the bottom of the ball, and the plastic and sewage also flow into the dehydration cavity;

[0048] Then the dehydration assembly 7 starts to work, and the drum 701 rotates at a high speed to make the sewage flow out from the leakage hole, and the plastic is quickly dried.

[0049] The present invention separates the cleaning and dehydration spaces by arranging two chambers in one sphere, so that the two do not interfere with each other and are more efficient when working separately. By flipping the sphere, the working mode can be quickly switched without using two machines to work separately, thereby improving work efficiency.

[0050] As a further solution of the present invention: both ends of the outer shaft 303 are connected with pressure plates 304 .

[0051] The middle group of stirring rods 403 is connected to the cleaning shaft 402 through a connecting protective shell 404. A fixing plate B702 is fixedly connected to the middle of the rotating drum 701. The fixing plate B702 is sleeved on the outside of the outer shaft 303. The inside of the fixing plate B702 and the connecting protective shell 404 are both provided with hollow cavities and the inner walls are both provided with card grooves 405. Two lifting clamps 305 are fixed on the outside of the outer shaft 303. The two lifting clamps 305 are respectively located inside the fixing plate B702 and the connecting protective shell 404. Only one of the two lifting clamps 305 is engaged with the card groove 405 at the same time.

[0052] like Figure 5 As shown: the pressure plate 304 is a part of the spherical surface, and its groove faces the inside of the cleaning sphere. When the cleaning sphere 2 is flipped, the water will also flow. At this time, the pressure plate 304 located below will move downward under the action of the water flow, thereby driving the outer shaft 303 to move. When flipped again, the outer shaft 303 will move in the opposite direction. When the outer shaft 303 moves, the lifting clamp 305 fixed on its outer surface will also move accordingly. The two lifting clamps 305 will switch to fit between the two slots 405, thereby realizing the switching between the cleaning mode and the dehydration mode.

[0053] The present invention utilizes the flow of water when the cleaning ball is flipped and the effect of gravity to automatically switch between the cleaning mode and the dehydration mode. When the cleaning cavity is flipped to the bottom, it automatically cleans, and when the dehydration cavity is flipped to the bottom, it automatically dehydrates. The whole process is automated with a low failure rate. There will be no mechanical damage due to human operating errors, and work efficiency is also improved.

[0054] As a further solution of the present invention: As a further solution of the present invention: The deceleration gear set includes a ring gear 603, a planetary gear 604, and a sun gear 605. The sun gear 605 is sleeved on the outside of the outer shaft 303. The middle rotating shaft of the planetary gear 604 is fixedly connected to the top of the fixed plate A401. The top of the ring gear 603 is fixedly connected to the rotating plate 602. The telescopic rod includes a rotating rod 606. One end of the rotating rod 606 is fixedly connected to the rotating plate 602. The other end of the rotating rod 606 is connected to an inner rod 608 through a spring B607. One end of the inner rod 608 close to the rotating rod 606 is inserted into the interior of the rotating rod 606, and the same end is also connected to a thin rod 609. The other end of the thin rod 609 is inserted into the interior of the rotating plate 602. Two symmetrical liftable lifting blocks 611 are provided on the top of the rotating plate 602.

[0055] The flip assembly 5 also includes a protective shell 507, and the telescopic block 502, spring A503, bevel gear A505 and bevel gear B506 are all arranged inside the protective shell 507. The bottom of the protective shell 507 is provided with a groove to facilitate the movement of the lifting block 611. The bottom of the telescopic block 502 is provided with an inclined groove 504, and the bottom inclination angle of the inclined groove 504 is the same as the top inclination angle of the lifting block 611.

[0056] An oil groove 610 is provided inside the rotating plate 602 . The oil groove 610 has three openings, which are respectively connected to the thin rod 609 and the two lifting blocks 611 . The oil groove 610 is filled with hydraulic oil.

[0057] Second embodiment: Figure 6-9 As shown, when the power motor 301 is started, the slow gear set will work normally regardless of whether it is in the cleaning mode or the dehydration mode. The slow gear set drives the rotating plate 602 and the telescopic rod to rotate slowly. At this time, the rotation of the telescopic rod actually plays a timing role. When the telescopic rod rotates half a circle to reach the position of the arc-shaped raised plate 601, the inner rod 608 contracts inward and drives the thin rod 609 to move inward. At this time, the hydraulic oil will be squeezed, and the lifting block 611 will move upward. During the upward movement of the lifting block 611, the telescopic block 502 will be pushed toward the center of the circle. At this time, the bevel gear A505 and the bevel gear B506 will engage with each other. Since the bevel gear A505 remains stationary, the bevel gear B506 will rotate with the rotation of the power motor. At this time, the cleaning ball 2 will flip over, thereby realizing the conversion of the working mode.

[0058] In the present invention, since the rotation of the telescopic rod is affected by the output power of the power motor 301, and the cleaning and dehydration work are also affected by the output power of the power motor 301, the mode switching time will change with the change of the output power of the power motor 301. When the output power of the power motor 301 is high, the cleaning and dehydration work will be fast, and the mode switching speed will also become faster, and vice versa. In this way, it can be ensured that the plastic is fully cleaned and will not be affected by the working voltage.

[0059] In summary, the present invention integrates a cleaning component and a dehydration component in the same device, and realizes mode switching through a flip component, which is controlled by an automatic control component, thereby ensuring that the operation of each component will not affect each other during mode switching. In addition, the present invention ensures that the cleaning device modes will not work at the same time through the linkage of the mechanical structure at the beginning of the design, thereby preventing waste of resources and improving the work efficiency when working in a single mode.
