Description

Technical Field

[0002] In the plastic granulation process, there are mainly hot cutting method and cold cutting method. Among them, the specific steps of the cooling method are: firstly, the plastic strips are made by the extruder, then the plastic strips are cooled by cooling water, then the cooled plastic strips are dried by the drying device, and finally the plastic strips are cut into particles of the required size by the pelletizing device.

[0035] The drawings are only used for illustrative purposes and should not be construed as limitations of this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product.

[0036] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the utility model is further described below in conjunction with the drawings and embodiments.

[0037] A drying device for a plastic granulator as shown in the attached drawings comprises a frame 1 and a water cooling pool arranged on the frame 1, and a shaking mechanism, a wiping mechanism and an air drying mechanism are arranged in sequence behind the water cooling pool along the feeding direction of the plastic strips;

[0038] The shaking mechanism includes a rotating shaft 31 rotatably connected to the frame 1, and a mounting plate 32 is provided at the end of the rotating shaft 31. A plurality of supporting rods 33 are evenly distributed on the mounting plate 32 along the circumference of the rotating shaft 31, and the supporting rods 33 extend along the axial direction of the rotating shaft 31;

[0039] The wiping mechanism includes a pressure plate 41, a sponge roller assembly arranged below the pressure plate 41, and a squeezing roller 42 arranged below the sponge roller assembly. The sponge roller assembly includes a core shaft 43, a rotating cylinder 44 is rotatably sleeved on the outer side of the core shaft 43, and a sponge sleeve 45 is integrally sleeved on the outer side of the rotating cylinder 44; as an example, the core shaft 43 is integrally connected to the frame 1.

[0040] A power assembly is connected between the rotating shaft 31 and the rotating cylinder 44 , and the power assembly can drive the rotating shaft 31 and the rotating cylinder 44 to rotate.

[0041] The air drying mechanism includes an air drying box 51 , the front and rear ends of the air drying box 51 are provided with through holes 511 for the plastic strips to pass through, a pair of sides of the air drying box 51 are respectively provided with air inlet holes and air exhaust holes, and the air inlet holes are connected to the blower 53 through the air inlet pipe 52 .

[0042] First, the plastic strips after cooling pass through the shaking mechanism. The rotating shaft 31 of the shaking mechanism drives the supporting rod 33 to rotate around the axis of the rotating shaft 31 through the mounting plate 32, causing the plastic strips to shake and shake off the water on the plastic strips, thereby performing a preliminary dehydration process on the plastic strips. Next, the plastic strips pass through the wiping mechanism. The rotating cylinder 44 of the wiping mechanism drives the sponge sleeve 45 to wipe the plastic strips to absorb the water on the plastic strips, thereby further dehydrating the plastic strips. Finally, the plastic strips pass through the air-drying mechanism. The blower 53 blows air to the plastic strips, thereby air-drying the plastic strips.

[0043] Preferably, a circulation pipe 21 is connected between the front and rear ends of the water cooling pool, and a water pump and a heat dissipation component are provided on the circulation pipe 21 . The heat dissipation part of the heat dissipation component is located in the air inlet pipe 52 .

The capillary tube 23 is arranged to penetrate the air inlet pipe 52 , and a heat sink 25 is integrally connected to the outer wall of the capillary tube 23 .

[0045] When in use, the water pump drives the cooling water in the water cooling pool to flow through the heat dissipation component, and transfers the heat of the cooling water to the heat dissipation component. At the same time, the blower 53 drives the air to flow through the heat sink, so that the air takes away the heat on the heat dissipation component, thereby cooling the cooling water. In addition, the air absorbs heat and heats up when flowing through the heat dissipation component, and then flows to the air drying box 51 driven by the blower 53 to air dry the plastic strips in the air drying box 51. The whole process not only achieves the cooling of the cooling water, but also realizes the recovery of the heat of the cooling water, and is conducive to improving the efficiency of air drying.

[0047] It should be noted that after passing through the air drying box 51, the air continues to flow to the air supply chamber 431 through the air supply pipe 54, and then blows to the sponge cover 45 through the air supply hole 432 and the air vent hole 441, which is conducive to dehydration of the sponge cover 45. The air blown outward from the inside of the sponge cover 45 is easier to take away the moisture on the sponge cover 45 than the air blown inward from the outside of the sponge cover 45.

[0048] Preferably, the power assembly includes a driving wheel 61 connected to the rotating shaft 31 , a driven wheel 62 connected to the rotating cylinder 44 , and a transmission belt 63 connecting the driving wheel 61 and the driven wheel 62 , and the driving wheel 61 is connected to a motor 64 .

The water collecting plate 7 can guide the cooling water removed from the plastic strip into the water cooling pool.

[0050] Preferably, in order to prevent the plastic strip at the pelletizing device from shaking, thereby affecting the pelletizing accuracy, an anti-shake component is provided between the shaking mechanism and the wiping mechanism to prevent the shaking mechanism from causing the plastic strip located behind the anti-shake component to shake.

[0051] The anti-shake assembly includes a support plate 81, and a press roller 82 disposed above the support plate 81 and rotatably connected to the frame 1, the end of the press roller 82 is rotatably connected to a moving seat 83, the frame 1 is provided with a guide rail 84 slidably connected to the moving seat 83, the guide rail 84 is slidably connected to an adjustment seat 85 above the moving seat 83, an elastic member 86 is connected between the moving seat 83 and the adjustment seat 85, the adjustment seat 85 is rotatably connected to a screw rod 87 extending vertically, the screw rod 87 is threadedly connected to the frame 1, and a hand wheel 88 is provided at the top of the screw rod 87. It can be understood that the user can adjust the downward pressure of the press roller 82 by turning the hand wheel 88.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description.
