Description

Technical Field

[0001] The utility model relates to the technical field of plastic strip dewatering, in particular to a plastic strip dewatering device for processing plastic particles. Background Art

[0002] In the process of plastic pellet processing, the plastic raw materials need to be put into the melting equipment, and the melting equipment forms the molten material, and the molten material is formed into continuous plastic strips under the action of the extruder. In order to accelerate the hardening of the plastic strips, the plastic strips are usually passed through cooling water continuously, and then quickly cooled and formed, so that the plastic strips can be cut into granules under the action of the pelletizer.

[0003] After the plastic strips are output from the cooling water, there is water on their surface and they are cut into granules by the pelletizer. Therefore, the cut plastic granules are relatively moist. If left for a long time, they are very likely to become moldy, affecting the sales and use of the plastic granules.

[0004] In order to solve the above problems, devices for reducing the humidity of plastic strips have appeared on the market. For example, a Chinese patent with patent publication number CN214725757U discloses a plastic extrusion water removal device, which includes a water shaking mechanism, a water wiping mechanism, and an air-drying mechanism. The water shaking mechanism includes a first water tank, a drain plate with drain holes, and a water shaking assembly. The water shaking assembly includes a spring, a roller seat, and a roller. The water wiping mechanism includes a second water tank and a water wiping assembly. The water wiping assembly includes a brush head seat, bristles, and a water pump. The air-drying mechanism includes a third water tank, an air tank with a strip-shaped air outlet, and a blower. When the plastic strip is being transported, the drain hole contacts the plastic strip to scrape off large water droplets. The plastic strip drives the water shaking assembly to shake, thereby driving the plastic strip and the water shaking assembly to shake together. The roller shakes off the water droplets on the plastic strip. The plastic strip passes through the bristles, and the bristles wipe off the moisture on the surface of the plastic strip. The water pump removes the moisture on the bristles, and the wind from the blower passes through the strip-shaped air outlet to form high-pressure wind. The high-pressure wind completely removes the residual moisture on the surface of the plastic strip, and has a good water removal effect.

[0005] Although the device provided by the above patent can reduce the humidity of the plastic strip, it involves many mechanisms and therefore occupies a large space, which is not conducive to the arrangement of the entire set of equipment for the production of plastic particles, and the effect of brushing away moisture on the surface of the plastic strip is not good.

[0027] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0028] Example 1

[0029] like Figure 1 , Figure 2 As shown, a plastic strip dewatering device for processing plastic particles includes a bin body 1, a first dewatering mechanism 2 and a second dewatering mechanism 3 distributed above and below, the first dewatering mechanism 2 is supported on the top of the bin body 1, and the second dewatering mechanism 3 is adjustably arranged on the top of the first dewatering mechanism 2, and the length and width of the bin body 1 are both larger than the length and width of the first dewatering mechanism 2 and the second dewatering mechanism 3, so that a water flow channel is formed between the bin body 1 and the first dewatering mechanism 2. The first dewatering mechanism 2 includes a bottom plate 21 and a first absorbent cotton 23, the first absorbent cotton 23 is arranged above the bottom plate 21, and the second dewatering mechanism 3 includes a top plate 32 and a second absorbent cotton 31, the second absorbent cotton 31 is arranged below the top plate 32. When the device is used to dewater the plastic strip, the second dewatering mechanism 3 is controlled to rise relative to the first dewatering mechanism 2, and the plastic strip is moved from one end of the gap formed by the first dewatering mechanism 2 and the second dewatering mechanism 3 to the other end, and then the second dewatering mechanism 3 is controlled to descend, so that the first absorbent cotton 23 and the second absorbent cotton 31 contact each other, and at the same time, the first absorbent cotton 23 and the second absorbent cotton 31 wrap the plastic strip and do not affect the movement of the plastic strip. After the plastic strip passes through the absorbent cotton, it is put into the pelletizer, and the plastic strip is controlled to move under the action of the pelletizer. In the process of the movement of the plastic strip, the first absorbent cotton 23 and the second absorbent cotton 31 absorb the moisture on the surface of the plastic strip, and the moisture content of the absorbent cotton gradually decreases along the moving direction of the plastic strip. When a large amount of water is absorbed by the absorbent cotton, the second water removal mechanism 3 can be controlled to descend relative to the first water removal mechanism 2, forcing the absorbent cotton to compress and remove water. The discharged water flows into the bin body 1 through the gap between the first water removal mechanism 2 and the bin body 1.

[0030] like Figure 3 As shown, in order to stably install the absorbent cotton on the bottom plate 21 and the top plate 32, rectangular baffles 26 are provided on the sides of the bottom plate 21 and the top plate 32 that are close to each other, and the ends of the first absorbent cotton 23 and the second absorbent cotton 31 that are away from each other are bonded and arranged in the rectangular baffles 26. The arrangement of the rectangular baffles 26 can limit the absorbent cotton to be stably placed relative to the bottom plate 21 and the top plate 32. In addition, leakage holes 25 are provided on the bottom plate 21 and the top plate 32. When the absorbent cotton is compressed and deformed, the discharged water is discharged through the leakage holes 25.

[0031] like Figure 2 , Figure 4As shown, in order to force the absorbent cotton to deform, a limiting rod 24 is provided at the end corner above the bottom plate 21, a threaded rod 22 is connected and penetrated through the edge of the middle part of the bottom plate 21 through a bearing, a limiting hole 33 is provided at the end corner of the top plate 32, a threaded hole 34 is provided in the middle of the edge of the top plate 32, the top thread of the threaded rod 22 penetrates the threaded hole 34, the limiting rod 24 penetrates the limiting hole 33, and the lower ends of the two threaded rods 22 are connected by a transmission belt 27. When the absorbent cotton needs to be compressed, the staff controls the threaded rod 22 to rotate. Since the thread of the threaded rod 22 penetrates the top plate 32, the top plate 32 is controlled to descend. The descending top plate 32 and the bottom plate 21 squeeze the absorbent cotton at the same time, thereby draining the moisture in the absorbent cotton. With the cooperation of the limiting rod 24 and the limiting hole 33, the top plate 32 is stably raised and lowered relative to the bottom plate 21.

[0032] Example 2

[0033] like Figure 1 , Figure 2 As shown, a plastic strip dewatering device for processing plastic particles includes a bin body 1, a first dewatering mechanism 2 and a second dewatering mechanism 3 distributed above and below, the first dewatering mechanism 2 is supported on the top of the bin body 1, and the second dewatering mechanism 3 is adjustably arranged on the top of the first dewatering mechanism 2, and the length and width of the bin body 1 are both larger than the length and width of the first dewatering mechanism 2 and the second dewatering mechanism 3, so that a water flow channel is formed between the bin body 1 and the first dewatering mechanism 2. The first dewatering mechanism 2 includes a bottom plate 21 and a first absorbent cotton 23, the first absorbent cotton 23 is arranged above the bottom plate 21, and the second dewatering mechanism 3 includes a top plate 32 and a second absorbent cotton 31, the second absorbent cotton 31 is arranged below the top plate 32. When the device is used to dewater the plastic strip, the second dewatering mechanism 3 is controlled to rise relative to the first dewatering mechanism 2, and the plastic strip is moved from one end of the gap formed by the first dewatering mechanism 2 and the second dewatering mechanism 3 to the other end, and then the second dewatering mechanism 3 is controlled to descend, so that the first absorbent cotton 23 and the second absorbent cotton 31 contact each other, and at the same time, the first absorbent cotton 23 and the second absorbent cotton 31 wrap the plastic strip and do not affect the movement of the plastic strip. In the process of the movement of the plastic strip, the first absorbent cotton 23 and the second absorbent cotton 31 absorb the moisture on the surface of the plastic strip, and the moisture content of the absorbent cotton gradually decreases along the moving direction of the plastic strip. When a large amount of water is absorbed by the absorbent cotton, the second water removal mechanism 3 can be controlled to descend relative to the first water removal mechanism 2, forcing the absorbent cotton to compress and remove water. The discharged water flows into the bin body 1 through the gap between the first water removal mechanism 2 and the bin body 1.

[0034] like Figure 3As shown, in order to stably install the absorbent cotton on the bottom plate 21 and the top plate 32, rectangular baffles 26 are provided on the sides of the bottom plate 21 and the top plate 32 that are close to each other, and the ends of the first absorbent cotton 23 and the second absorbent cotton 31 that are away from each other are bonded and arranged in the rectangular baffles 26.

When the absorbent cotton needs to be compressed, the staff controls the threaded rod 22 to rotate. Since the thread of the threaded rod 22 penetrates the top plate 32, the top plate 32 is controlled to descend. The descending top plate 32 and the bottom plate 21 squeeze the absorbent cotton at the same time, thereby draining the moisture in the absorbent cotton. With the cooperation of the limiting rod 24 and the limiting hole 33, the top plate 32 is stably raised and lowered relative to the bottom plate 21.

[0036] like Figure 1 , Figure 5 As shown, in order to further reduce the humidity of the plastic strip, a drying mechanism 4 is provided at the end of the warehouse body 1, and the drying mechanism 4 includes a support frame 41, a driving roller 42 and a limiting roller 43 distributed up and down, and two shells 44 distributed up and down.

The side walls of the two shells 44 close to each other are provided with heating wires 45, and the heating wires 45 and the motor are connected to the control box, which is provided on the warehouse body 1. By operating the control box, the heating wire 45 and the motor can be controlled to work, and the driving roller 42 can be controlled to rotate by the motor. Since the limiting roller 43 and the driving roller 42 clamp the plastic strip, when the driving roller 42 rotates, the plastic strip is controlled to move. The moving plastic strip passes through the upper and lower shells 44 , and the space formed by the two shells 44 is heated by the heating wire 45 , thereby evaporating the residual moisture on the plastic strip, further reducing the humidity of the plastic strip.
