Abstract
Description
Technical Field
[0001] The invention relates to the field of plastic granulation equipment, in particular to a masterbatch water-cooling granulation device. Background Art
[0002] The masterbatch is added to the inside of the melt extruder, and the plastic material in the molten state is extruded through the plastic die head under the action of the melt extruder. After the softened plastic strip is extruded, the staff needs to pick up the end of the plastic strip, and then quickly immerse it in a water cooling tank to quickly cool and solidify the softened plastic strip. The solidified plastic strip is then pulled into the pelletizer, and under the action of the pelletizer, the solidified plastic strip is cut into granules.
[0003] After the plastic strips solidify in the cold water trough, they are transported from the cold water trough to the pelletizer. The strips have a large span and are covered with water droplets. During the transport process, a large amount of water droplets will fall onto the ground between the cold water trough and the pelletizer. Even if a water collection box is placed between the two, the water droplets falling from a high altitude will hit the inner wall of the water collection box or the water surface, splashing many small water droplets. This will cause the pelletizing production area to be very humid, affecting the plant environment for pelletizing operations. In addition, as the plastic strips gradually carry the water out of the cold water trough, the cooling water in the cold water trough will decrease, ultimately affecting the water-cooled solidification effect of the plastic strips.

[0032] It also includes: a water absorption unit for absorbing moisture adhered to the surface of the plastic strip, the water absorption unit is mounted on the top of the end of the water cooling frame tank 1 away from the melt extruder, and a sponge sheet 17 is further provided below the water absorption unit. The sponge sheet 17 is fixed inside the water cooling frame tank 1 and is located above the water surface inside the water cooling frame tank 1;
[0033] The auxiliary drying unit is used to supply air to the surface of the plastic strips that have been wiped of moisture, so that the surface of the plastic strips is in a dry state when entering the pelletizer. The auxiliary drying unit is mounted on the top of the water absorption unit.
[0034] The water absorption unit includes two rounded rectangular frame plates 4 fixed to the upper edge of the water-cooling frame groove 1 and distributed symmetrically in the front and back. Two first rotating shafts 5 are rotatably arranged between the two rounded rectangular frame plates 4. A first gear 6 is fixedly sleeved on both ends of each first rotating shaft 5, and the two first gears 6 on the same side are located on the inner side of the same rounded rectangular frame plate 4. A double-sided toothed belt 7 is installed for transmission between the two first gears 6 on the same side. A number of equally distributed meshing teeth are fixedly arranged on the inner wall of the rounded rectangular frame plate 4, and a number of equally distributed second gears 11 are installed for transmission between the double-sided toothed belt 7 and the inner wall of the rounded rectangular frame plate 4 on the same side. A receiving frame plate 12 is also fixedly arranged at the inner center of each rounded rectangular frame plate 4, and the receiving frame plate 12 is distributed between the two first gears 6. The receiving frame plate 12 plays a bearing role on the double-sided toothed belt 7 to avoid the middle section of the double-sided toothed belt 7 The part is bent and deformed, and a second rotating shaft 9 is fixedly assembled between two second gears 11 distributed in opposite directions, and a sponge water-absorbing sleeve 10 is fixedly sleeved on the outer surface of the second rotating shaft 9. An external fixed frame of one of the rounded rectangular frame plates 4 is provided with an electric motor 8, and the output end of the motor 8 is fixed to the end of one of the first rotating shafts 5. When the motor 8 drives the first rotating shaft 5 to rotate, the double-sided toothed belt 7 starts to transmit. Since the rounded rectangular frame plate 4 and the meshing teeth inside it are fixed, multiple second gears 11 will rotate between the double-sided toothed belt 7 and the rounded rectangular frame plate 4, and during the rotation process, they will also transform their position along the gap between the double-sided toothed belt 7 and the rounded rectangular frame plate 4, that is, make a circular displacement between the double-sided toothed belt 7 and the rounded rectangular frame plate 4. A water-squeezing component is also provided between the two rounded rectangular frame plates 4, and the water-squeezing component is used to squeeze out the water absorbed in the sponge water-absorbing sleeve 10.
[0035] The water squeezing component includes an optical axis 13 distributed in an upper and lower manner. The lower part of the double-sided toothed belt 7 passes through the two optical axes 13.

The water squeezing splint 14 on the same side is connected to the baffle 15. A first spring 16 is fixedly arranged between the plates 15. The first spring 16 applies elastic pressure to the water-squeezing splints 14, so that the movable ends of the two water-squeezing splints 14 are elastically closed together. When the second rotating shaft 9 carries the sponge water-absorbing sleeve 10 through the two water-squeezing splints 14, the two water-squeezing splints 14 can squeeze the sponge water-absorbing sleeve 10 to squeeze out the water inside the sponge water-absorbing sleeve 10. After the second rotating shaft 9 carries the sponge water-absorbing sleeve 10 and separates from the two water-squeezing splints 14, the two water-squeezing splints 14 are reset and closed again under the action of the first spring 16.
[0036] The auxiliary drying unit includes a wind tube 32 horizontally mounted above two rounded rectangular frame plates 4.

The outer surface of the wind tube 32 is embedded with an exhaust duckbill 33. The end of the wind tube 32 close to the gear differential 43 is provided with a plurality of air inlet holes 42. The gear differential 43 is a gear speed increaser. When the drive shaft 36 rotates at a high speed with the blade-type wind wheel 35, it can inhale external air through the air inlet holes 42 and spray it out through the exhaust duckbill 33, and send air to the surface of the wiped plastic strip for drying.
[0037] Example 2: Please refer to Figure 6 and Figure 7 This embodiment is a further explanation of the first embodiment. A pressing component is further provided on the top of the rounded rectangular frame plate 4. The pressing component is used to improve the tightness of the fit between the plastic strip and the sponge water-absorbing sleeve 10.
[0038] The pressing component includes a connecting plate 29 located above the two rounded rectangular frame plates 4, and at least two suspension rods 30 are fixedly provided at the bottom of the connecting plate 29, and a rubber rotary cylinder 31 is rotatably sleeved on the outer surface of the suspension rod 30, and a first slide bar 21 is fixedly provided at one end of the connecting plate 29 away from the motor 8, the first slide bar 21 is vertically distributed with the connecting plate 29, and the first slide bar 21 extends downward, the connecting plate 29 is parallel to the upper end plane of the rounded rectangular frame plate 4, a sliding disc 20 is fixedly provided at the bottom of the first slide bar 21, and a limiting sleeve 19 is slidably sleeved on the outer surface of the sliding disc 20, A second spring 22 is fixedly arranged between the upper end of the disk 20 and the limiting sleeve 19. The second spring 22 applies downward elastic pressure to the first sliding rod 21 and the connecting plate 29 through the sliding disk 20, so that multiple rubber rollers 31 press the plastic strip downward. When the sponge water-absorbing sleeve 10 moves to the bottom of the suspension rod 30, the plastic strip can fit tightly against the surface of the sponge water-absorbing sleeve 10. The elastic force generated by the second spring 22 will not cause large deformation of the sponge water-absorbing sleeve 10. A reciprocating moving part is also arranged between the bottom of the limiting sleeve 19 and the rounded rectangular frame plate 4.
[0039] The reciprocating moving part includes a synchronous gear 25 fixedly sleeved on one end of each first rotating shaft 5 away from the motor 8, and a transmission belt 26 is installed between the two synchronous gears 25. The outer surface of the transmission belt 26 is also fixedly provided with a number of equally spaced limiting ball columns 27. The transmission belt 26 is a transmission chain or a transmission toothed belt. The bottom outer surface of the limiting sleeve 19 is fixedly sleeved with a positioning seat block 18, and the interior of the positioning seat block 18 is slidingly equipped with a second slide rod 23. The second slide rod 23 is fixed to the rounded rectangular frame plate 4. The outer sleeve of each second slide rod 23 is provided with a tension spring 24, and the two ends of the tension spring 24 are fixed. The ends are fixed to the rounded rectangular frame plate 4 and the positioning seat block 18 respectively. The bottom of the limiting sleeve 19 is fixedly provided with an inclined inclined plate 28, and the limiting ball column 27 and the inclined plate 28 are slidingly assembled. During the transmission process of the first rotating shaft 5 with the transmission belt 26 through the synchronous gear 25, the inclined plate 28 will be pushed by the limiting ball column 27, so that the positioning seat block 18 moves laterally on the surface of the second slide rod 23, and the rubber rotating cylinder 31 can rub the plastic strip it contacts with slightly, so that the plastic strip can rotate back and forth slightly, so that the moisture adhered to the surface of the plastic strip can contact the sponge water-absorbing sleeve 10 more fully.
[0040] Example 3: Please refer to Figures 8-10 This embodiment is a further explanation of other embodiments. The upper port of the exhaust duckbill 33 is circular and open, and the lower port is slit-shaped. The slit-shaped port can make the discharged wind finer and the wind speed greater.
[0041] The upper port of the exhaust duckbill 33 is slidably sleeved on the bottom of the air duct 32, and both ends of the exhaust duckbill 33 are fixed with a rotating column 34 that rotates through the air duct 32. The rotating column 34 coincides with the axis of the circular upper port of the exhaust duckbill 33. There is an elastic reset component between the rotating column 34 and the air duct 32, and a driving component is also provided between the end of the driving shaft 36 and the elastic reset component. The driving component is used to drive the elastic reset component to reciprocate the exhaust duckbill 33. When the driving shaft 36 rotates, the elastic reset component can be intermittently triggered by the driving component, so that the exhaust duckbill 33 can intermittently rotate back and forth inside the air duct 32.
[0042] The elastic reset component includes a hollow gear 39 fixedly mounted on one end of the rotating column 34 near the motor 8. A concentric arc groove is provided inside the hollow gear 39, and a positioning block 40 is slidably assembled inside the arc groove. The positioning block 40 is fixed to the air cylinder 32, and a third spring 41 is fixedly arranged between one end of the positioning block 40 and the hollow gear 39. The third spring 41 is located inside the arc groove. In the initial state, when the third spring 41 is not compressed, the positions of the rotating column 34 and the exhaust duckbill 33 are fixed. When the hollow gear 39 is rotated, the rotating column 34 and the exhaust duckbill 33 will be deflected.
[0043] The driving component includes an inner gear ring 37 rotatably assembled on the outside of the driving shaft 36. The outer surface of the inner gear ring 37 is fixedly provided with several groups of gear blocks 38 equidistantly distributed around the circumference, and the number of gear blocks 38 in each group is 2-5. The gear blocks 38 are movably engaged with the hollow gear 39. There is a reduction transmission component between the driving shaft 36 and the inner gear ring 37. When the driving shaft 36 rotates at high speed, the inner gear ring 37 can rotate slowly. The reduction transmission component includes a third gear fixedly sleeved on the outer surface of the driving shaft 36, and a fourth gear is also transmission-assembled between the third gear and the inner gear ring 37. The fourth gear and the wind tube 32 are rotatably assembled.
[0044] Working principle: In this solution, refer to Figure 1-Figure 3 In the state, the movable ends of the two water squeezing splints 14 are facing the pelletizer, and the double-sided toothed belt 7 is driven by the motor 8 on the first rotating shaft 5. During the transmission process, the second gear 11 is simultaneously engaged with the double-sided toothed belt 7 and the teeth, so that several groups of second gears 11 can carry several second rotating shafts 9 and sponge water-absorbing sleeves 10 to move in a circular manner inside the rounded rectangular frame plate 4. During the circular movement, the sponge water-absorbing sleeves 10 can also rotate on their own, and several sponge water-absorbing sleeves 10 can move clockwise;
[0045] After guiding the plastic strip from the end of the melt extruder, the staff immerses it in the water of the water-cooled frame tank 1 and passes it through several guide rollers 3. The hardened plastic strip is lifted and placed between the upper portion of the two rounded rectangular frame plates 4 and the connecting plate 29. During the placement process, the staff first lifts the connecting plate 29, compressing the second spring 22. After the plastic strip passes between the connecting plate 29 and the upper portion of the two rounded rectangular frame plates 4, the connecting plate 29 is lowered. The elastic force exerted by the second spring 22 causes the rubber drum 31 to apply downward pressure to the plastic strip, ensuring close contact between the plastic strip and the surface of the sponge absorbent sleeve 10. After the exposed end of the plastic strip is inserted into the pelletizer's feeding structure, the continuous pelletizing operation can begin.
[0046] During the movement of the plastic strips into the pelletizer, the continuous circular movement of the plurality of sponge water-absorbing sleeves 10 absorbs the moisture adhering to the surface of the plastic strips multiple times, thereby ensuring that the moisture on the surface of the plastic strips is completely absorbed. In addition, during the transmission process of the first rotating shaft 5, the drive shaft 36 can also rotate at a high speed with the blade-type wind wheel 35, so that the slit-shaped port of the exhaust duckbill 33 delivers a high-speed airflow toward the surface of the wiped plastic strips, thereby drying the moisture on the surface of the plastic strips, thereby further ensuring that the plastic strips are in a dry state when entering the pelletizer.
[0047] When each sponge water-absorbing sleeve 10 passes between the two water-squeezing splints 14, the water absorbed therein will be squeezed out by the two water-squeezing splints 14. After being squeezed out, the water will drip along the surface of the water-squeezing splints 14 into the inside of the water-cooling frame tank 1. When a large amount of water drips, it can be received by the sponge sheet 17 inside the water-cooling frame tank 1, thereby preventing the squeezed water droplets from splashing when falling into the water-cooling frame tank 1. This not only ensures that the water level inside the water-cooling frame tank 1 will not drop rapidly, but also avoids splashing when water is recovered, thereby avoiding severe humidity in the processing plant environment.
