Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic cleaning, in particular to a resin ultrasonic cleaning device. Background Art

[0002] Ultrasonic cleaning uses the cavitation, acceleration and straight-forward flow effects of ultrasound in liquids to directly and indirectly affect liquids and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the cleaning purpose. Cleaning resin particles by ultrasonic cleaning can improve cleaning efficiency.

[0003] After searching, a Chinese patent with publication number: CN221017721U discloses an ultrasonic cleaning device for resin cleaning, including an ultrasonic cleaning box, a movable door is movably connected to the middle of the front of the ultrasonic cleaning box, an observation window is fixedly connected to the middle of the front of the movable door, a drain pipe is fixedly connected to the middle of the lower part of one side of the ultrasonic cleaning box, and a controller is fixedly connected to the upper part of one side of the ultrasonic cleaning box.

[0004] Based on the above search and combined with actual problems, it is found that the existing ultrasonic cleaning equipment cannot remove and separate the impurity particles in the resin particles before cleaning the resin particles. If the impurity particles are mixed into the cleaning liquid along with the resin particles, then under the action of ultrasonic waves, the impurity particles will produce high-frequency vibrations, and the vibrating impurity particles will collide and rub with the resin particles, which can easily cause damage or breakage on the surface of the resin particles, reducing the size uniformity of the resin particles. Summary of the invention

[0005] In order to solve the problem that the existing ultrasonic cleaning equipment cannot remove and separate the impurity particles in the resin particles before cleaning the resin particles, if the impurity particles are mixed into the cleaning liquid along with the resin particles, then under the action of ultrasonic waves, the impurity particles will produce high-frequency vibrations, and the vibrating impurity particles will collide and rub with the resin particles, which may easily cause damage or rupture to the surface of the resin particles, thereby reducing the size uniformity of the resin particles.

[0042] In a possible implementation manner, the vibration mechanism includes a first rotating shaft 102 that penetrates and rotates inside the first housing 101, a first magnet 107 and a second magnet 108 (such as Fig. 9 As shown in the figure, two first rollers 103 are fixed at both ends of the first rotating shaft 102, and a rotating drum 109 is fixed at the position of the sliding bar 105 on the outer side of the first rotating shaft 102, and a plurality of intermediate magnets 110 arranged in a circle are arranged inside the rotating drum 109, the first magnet 107 and the second magnet 108 have the same magnetic poles facing each other, and the magnetic poles between each two adjacent intermediate magnets 110 are arranged in opposite directions;

[0043] The vibration mechanism is used to drive the sliding bar 105 to move forward and backward at high frequency, thereby driving the vibration plate 106 to vibrate, thereby grinding the impurities on the surface of the resin particles.

[0044] In a possible implementation, wiping cotton 111 is disposed on both sides of each vibration plate 106, and one side of each wiping cotton 111 is in a wavy structure;

[0045] The wiping cotton 111 can polish the resin particles, remove and separate the foreign particles adhering to the resin particles without damaging the resin particles, and remove the impurities on the surface of the resin particles. The wavy structure can increase the contact area between the wiping cotton 111 and the resin particles, thereby improving the cleaning efficiency.

[0046] In a possible embodiment, the stirring mechanism includes a second rotating shaft 202 that is rotatably connected to the inside of the second shell 201 and a plurality of driven shafts 205 that are evenly rotatably inserted on one side of the second shell 201, two second rollers 203 are fixed at both ends of the second rotating shaft 202, and a driving bevel gear 204 is fixed on the outer side of the second rotating shaft 202 at the position of each driven shaft 205, a driven bevel gear 206 that meshes with the driving bevel gear 204 is fixed at one end of each driven shaft 205, and a plurality of stirring blades 207 are fixed at the other end of each driven shaft 205;

[0047] Through multiple stirring mechanisms, the resin particles falling on the upper side of the screen plate 12 can be stirred, so that the resin particles in contact with the wiping cotton 111 are separated from the wiping cotton 111, and the resin particles away from the wiping cotton 111 are moved toward the side of the wiping cotton 111, so that the resin particles at various positions on the upper side of the screen plate 12 can contact with the wiping cotton 111, thereby improving the cleaning effect of the resin particles, fully removing and separating impurities on the surface of the resin particles, further improving the cleanliness of the resin particles, and avoiding damage to the resin particles caused by vibration of impurity particles.

[0048] In a possible implementation manner, two friction plates 14 (such as Figure 7 As shown), one side of the two friction plates 14 is in contact with the outer side of each first roller 103 and the second roller 203;

[0049] The friction plate 14 is used to apply friction force to the second roller 203 and the first roller 103 in the stirring mechanism and the vibration mechanism, so that the vibration mechanism and the stirring mechanism start to operate when they move to the side close to the screen plate 12.

[0050] In a possible implementation, an impurity collecting groove 11 is provided on the lower side of the two cavities 4, and a sieve plate 12 is provided on the upper side of the impurity collecting groove 11;

[0051] The resin particles slide along the upper side of the sieve plate 12 toward one end of the discharge port 10, so that the impurity particles mixed between the resin particles can fall into the inner side of the impurity collecting tank 11 through the sieve holes of the sieve plate 12. The inner diameter of the sieve holes of the sieve plate 12 is smaller than the diameter of the resin particles, so the impurities in the resin particles can be quickly separated.

[0052] In a possible embodiment, the resin collection mechanism includes two lifting mechanisms vertically arranged at both ends of the inner side of the cleaning tank 6 and a pushing mechanism arranged on the upper side of the cleaning tank 6; the lifting mechanism includes two second belt rollers 301 that are rotatably connected to one end of the inner side of the cleaning tank 6, and a second motor 302 installed on the outer side of the box body 1 for driving the second belt rollers 301. The outer sides of the two second belt rollers 301 are connected to the belt 2 303, and the outer sides of the belt 2 303 are evenly arranged with a plurality of lifting plates 304, and each lifting plate 304 is provided with a water leakage The diameter of the water leakage hole is smaller than the size of the resin particles; the pushing mechanism includes two horizontal plates 306 fixed to the inner side of the box body 1, a screw 308 is rotatably connected between the two horizontal plates 306, and two guide rods 309 are fixed between the two horizontal plates 306, a third motor 307 for driving the screw 308 to rotate is installed on one side of one horizontal plate 306, and a movable frame 310 is threadedly connected to the outer side of the screw 308, and the movable frame 310 is slidably sleeved on the outer side of the two guide rods 309, and a pushing comb plate 311 (such as Figure 8 shown);

[0053] The resin particles at the bottom of the cleaning tank 6 are pushed to the end of the cleaning tank 6 by the pushing mechanism in the resin collecting mechanism, and the resin particles pushed to the end of the cleaning tank 6 can be lifted upward by the lifting mechanism therein. A water leakage hole is provided on each lifting plate 304, and the diameter of the water leakage hole is smaller than the size of the resin particles. Therefore, the resin particles will not leak out through the water leakage hole, while the cleaning liquid containing fine impurities can leak out through the water leakage hole, and then the resin particles will fall to the inside of the resin collecting tank 7, so that the cleaned resin particles are quickly separated from the cleaning liquid, ensuring that the cleaning time of all resin particles is close, preventing some resin particles from being in the cleaning liquid for a long time, resulting in excessive cleaning, thereby accelerating the wear of the resin particles, and further reducing the probability of resin particles breaking during ultrasonic cleaning.

[0054] Working principle: when in use, the resin particles are put into the inner side of the hopper 3, and then the special ultrasonic cleaning liquid is poured into the inner side of the cleaning tank 6, and then the two first motors 9 are controlled to run in the reverse direction, thereby driving the two first belt rollers 8 at both ends to rotate in the reverse direction, and the two first belt rollers 8 respectively drive the other two first belt rollers 8 and the two belts 5 to rotate in the reverse direction;

[0055] The resin particles located on the inner side of the hopper 3 fall on the upper sides of the two belts 5 through the two feed ports 13 respectively. Under the rotating conveying action of the belt 5, the resin particles on the upper side are driven to move first to the end away from the discharge port 10. As the belt 5 rotates, the resin particles will fall on the upper side of the screen plate 12, but the belt 5 will drive the first shell 101 and the second shell 201 on the outer side to continue to rotate. The vibration plate 106 on one side of the first shell 101 applies a thrust to the resin particles falling on the upper side of the screen plate 12, so that the resin particles slide along the upper side of the screen plate 12 toward one end of the discharge port 10, so that the impurity particles mixed between the resin particles can pass through the sieve holes of the sieve plate 12 and fall to the inner side of the impurity collecting tank 11. The inner diameter of the sieve holes of the sieve plate 12 is smaller than the diameter of the resin particles, so the impurities in the resin particles can be quickly separated.

[0056] When each of the first shell 101 and the second shell 201 moves to a side close to the screen plate 12, the two first rollers 103 of the vibration mechanism can contact the friction plate 14, such as Figure 7 As shown, at this time, friction is generated between the moving first roller 103 and the friction plate 14, and the friction can drive the two first rollers 103 to rotate, and the two first rollers 103 drive the first rotating shaft 102 to rotate, and the first rotating shaft 102 drives the rotating drum 109 to rotate. Since a plurality of intermediate magnets 110 are arranged inside the rotating drum 109, and the magnetic poles between each two adjacent intermediate magnets 110 are arranged in opposite directions, and the first magnet 107 and the second magnet 108 have the same magnetic poles opposite to each other, the rotating drum 109 can drive the plurality of intermediate magnets 110 to rotate. When one magnetic pole of any intermediate magnet 110 is opposite to the first magnet 107 with the same pole, the other magnetic pole of the intermediate magnet 110 is opposite to the second magnet 108 with the opposite pole, and the sliding bar 105 can be driven to move rightward, as shown in FIG. Fig. 9 As shown, as the rotating drum 109 drives the plurality of intermediate magnets 110 to rotate, when an adjacent intermediate magnet 110 is aligned with the first magnet 107 and the second magnet 108, at this time, one magnetic pole of the adjacent intermediate magnet 110 is opposite to the first magnet 107, and the other magnetic pole of the intermediate magnet 110 is opposite to the second magnet 108, and at this time, the sliding bar 105 is driven to move leftward, as shown in FIG. Fig. 9As shown, when the first rotating shaft 102 and the rotating drum 109 rotate, the sliding bar 105 can be driven to move back and forth quickly, and the sliding bar 105 drives the vibration plate 106 to move back and forth. Since the wiping cotton 111 is arranged on both sides of the vibration plate 106, the two wiping cottons 111 can grind the resin particles, and the foreign particles adhering to the resin particles can be removed and separated without damaging the resin particles. By removing the impurities on the surface of the resin particles, it is possible to avoid the high-frequency vibration of the foreign particles during ultrasonic cleaning to damage the surface of the resin particles, thereby avoiding the resin particles from breaking and separating. The separated impurity particles can pass through the sieve plate 12 and fall into the inner side of the impurity collecting tank 11. One side of the two wiping cottons 111 is in a wavy structure, which can increase the contact area between them and the resin particles and improve the grinding efficiency. The vibration mechanism transmits the force to the sliding bar 105 through the action of magnetic force, thereby driving the sliding bar 105 to move forward and backward. At this time, the sliding bar 105 and the first shell 101 are elastically connected. When the ends of the sliding bar 105 and the vibration plate 106 touch the resin particles, the sliding bar 105 and the vibration plate 106 can play a certain buffering role to prevent the resin particles from being crushed.

[0057] When the belt 15 rotates, it also drives the second shell 201 to move. The second shell 201 is provided with a stirring mechanism. When the second shell 201 moves to the side close to the screen plate 12, the two second rollers 203 of the stirring mechanism contact one side of the two friction plates 14. Under the action of friction force, the two second rollers 203 and the second rotating shaft 202 can be driven to rotate. The second rotating shaft 202 drives multiple active bevel gears 204 to rotate. Each active bevel gear 204 drives the driven bevel gear 206 at the corresponding position to rotate through its teeth. Each driven bevel gear 206 drives each driven shaft 205 to rotate. Each The driven shaft 205 drives the multiple stirring pieces 207 at the end to rotate respectively. The multiple stirring pieces 207 can rotate to stir the resin particles falling on the upper side of the screen plate 12, so that the resin particles in contact with the wiping cotton 111 are separated from the wiping cotton 111, and the resin particles away from the wiping cotton 111 move toward the side of the wiping cotton 111, so that the resin particles at various positions on the upper side of the screen plate 12 can contact with the wiping cotton 111, thereby improving the cleaning effect of the resin particles, fully removing and separating the impurities on the surface of the resin particles, further improving the cleanliness of the resin particles, and avoiding the damage of the resin particles caused by the vibration of the impurity particles;

[0058] When the surface of the resin particles is cleaned, the resin particles are pushed to the position of the discharge port 10 under the conveying action of the belt 15, the first shell 101, and the second shell 201, and fall into the inner side of the cleaning tank 6 through the discharge port 10. The inner side of the cleaning tank 6 is filled with a cleaning liquid. The multiple ultrasonic transducers 2 can generate high-frequency vibrations, and the vibrations are transmitted to the cleaning liquid inside the cleaning tank 6 through the box 1, so that the resin particles can be ultrasonically cleaned. When the resin particles fall into the cleaning liquid, the resin particles can be further cleaned under the action of the cavitation effect. In order to remove the attachments on the surface of the particles, in order to prevent the impurity particles separated into the cleaning liquid from continuously rubbing the resin particles, it is necessary to control the third motor 307 of the pushing mechanism to drive the screw 308 to rotate, and the screw 308 drives the movable frame 310 to move horizontally through the thread. The third motor 307 controls the screw 308 to rotate forward and reverse, which can drive the movable frame 310 to move forward and reverse. The movable frame 310 drives the lower push comb plate 311 to move forward and reverse. The push comb plate 311 can push the larger resin particles to the two ends of the cleaning tank 6. The fine impurities are not pushed by the push comb plate 311, so the fine impurities remain in the cleaning liquid. When the resin particles move to the end of the cleaning tank 6, the second motors 302 of the two lifting mechanisms run to drive the second belt roller 301 to rotate, and the second belt roller 301 drives the belt 2 303 and another second belt roller 301 to rotate. The belt 2 303 drives multiple lifting plates 304 on its outside to rotate. The multiple lifting plates 304 can lift the resin particles pushed to the end of the cleaning tank 6 upward. Each lifting plate 304 is provided with a leakage hole. The diameter of the leakage hole is smaller than the size of the resin particles. Therefore, the resin particles will not leak out through the leakage hole, and the cleaning liquid containing fine impurities can leak out through the leakage hole. When lifted to the top, the resin particles fall to the inner side of the resin collecting tank 7, completing the separation of the resin particles and the cleaning liquid, ensuring that the cleaning time of all the resin particles is close, preventing some resin particles from being in the cleaning liquid for a long time, resulting in excessive cleaning, thereby accelerating the wear of the resin particles, and further reducing the probability of the resin particles breaking during ultrasonic cleaning.

[0059] The beneficial effects brought about by the technical solution provided by the embodiment of the present invention include at least:

[0060] (1) In the present invention, the resin particles are uniformly transported to the cleaning tank through a pre-cleaning mechanism. During the transportation process, multiple vibration plates are driven to move back and forth by multiple vibration mechanisms, thereby driving multiple wiping cottons to vibrate. The wiping cottons can grind the resin particles and remove and separate foreign particles adhering to the resin particles without damaging the resin particles. This can prevent the high-frequency vibration of the foreign particles from damaging the surface of the resin particles during ultrasonic cleaning, thereby preventing the resin particles from breaking.

[0061] (2) In the present invention, the resin particles falling on the upper side of the screen plate can be stirred evenly through a plurality of stirring mechanisms, so that the resin particles in contact with the wiping cotton are separated from the wiping cotton, and the resin particles away from the wiping cotton are moved toward the side of the wiping cotton, so that the resin particles at various positions on the upper side of the screen plate can contact with the wiping cotton, thereby improving the cleaning effect of the resin particles, fully removing and separating the impurities on the surface of the resin particles, further improving the cleanliness of the resin particles, and avoiding damage to the resin particles caused by vibration of the impurity particles.

[0062] (3) In the present invention, the resin particles at the bottom of the cleaning tank are pushed to the end of the cleaning tank by the pushing mechanism in the resin collecting mechanism, and the resin particles pushed to the end of the cleaning tank can be lifted upward by the lifting mechanism therein, and then the resin particles fall into the inner side of the resin collecting tank, so that the cleaned resin particles are quickly separated from the cleaning liquid, ensuring that the cleaning time of all resin particles is close, preventing some resin particles from being in the cleaning liquid for a long time, resulting in excessive cleaning, thereby accelerating the wear of the resin particles, and further reducing the probability of resin particles breaking during ultrasonic cleaning.

[0063] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
