Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic pellet production technology, specifically to a water-cooling device for plastic pellet production. Background Technology
[0002] Nylon plastic pelletizing is a common process in plastic recycling or plastic pelletizing production. After extruding plastic, the extruded plastic strip needs to be cooled and then cut into plastic pellets by a pelletizer.
[0003] Currently, water cooling is commonly used to cool plastic extrusion strips, followed by the removal of residual surface moisture by a water-absorbing component. However, existing technologies, such as CN113977797B, have water-absorbing components with fixed dimensions and lack adjustment capabilities. Therefore, when the water-absorbing component wears down over time or the diameter of the plastic extrusion strip changes, the water-absorbing component may be adjusted, but the contact pressure between the squeezing component and the water-absorbing component, as well as the water-absorbing gap, cannot be adjusted synchronously, leading to a decrease in squeezing efficiency. In severe cases, this can result in residual moisture retention and reduced subsequent drying efficiency.
[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content
[0005] The purpose of this invention is to provide a water-cooling device for the production of plastic granules that can effectively solve the above-mentioned technical problems.
[0006] To achieve the purpose of this utility model, the following technical solution is adopted:
[0007] A water-cooling device for producing plastic granules includes: a cold water tank; a vertical pole fixedly installed in the cold water tank near the material feeding side; a first water-absorbing component rotatably installed on the top of the vertical pole; a second water-absorbing component rotatably installed on the vertical pole and located below the first water-absorbing component, with a water-absorbing gap formed between the first water-absorbing component and the second water-absorbing component; a connecting rod disposed on the vertical pole; and a first water-squeezing component slidably installed on the connecting rod, forming a pressure zone with the first water-absorbing component through relative rotation.
[0008] Furthermore, the upright is arranged vertically, with its bottom end located inside the cold water tank and its top end located above the cold water tank.
[0009] Furthermore, a second water-squeezing component is also installed on the upright, and a pressure zone is formed between the second water-squeezing component and the second water-absorbing component.
[0010] Furthermore, the first dewatering component is rotatably connected to the connecting rod; the upright is rotatably connected to the second dewatering component.
[0011] Furthermore, one end of the connecting rod is rotatably mounted on the upright;
[0012] The other end of the connecting rod has a waist hole, and a slider is slidably connected in the waist hole. The slider is rotatably connected to the first water-squeezing component.
[0013] Furthermore, the connecting rod is configured as two pieces along the width direction of the cold water tank.
[0014] Furthermore, a connecting block is fixedly installed on each of the connecting rods, and a guide plate is installed between two of the connecting blocks; the guide plate is inclined from top to bottom toward the feeding end of the cold water tank.
[0015] Furthermore, the slider is rotatably connected to a threaded rod; the threaded rod extends out of the connecting rod and is threadedly connected to the connecting rod, and a rotating block is fixedly connected to the other end of the threaded rod.
[0016] Compared with the prior art, this utility model has the following beneficial effects: This application adopts an independent adjustment method for the relative positions of the first squeezing component and the first suction component, through a cold water tank; a vertical rod, fixedly installed in the cold water tank near the material feeding side; a first suction component, rotatably installed on the top of the vertical rod; a second suction component, rotatably installed on the vertical rod and located below the first suction component, forming a water absorption gap between the first and second suction components; a connecting rod, disposed on the vertical rod; and a first squeezing component, slidably installed on the connecting rod, forming a pressure zone with the first suction component through relative rotation.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0026] like Figures 1 to 5 As shown, this utility model relates to a water cooling device for the production of plastic granules, including: a cold water tank 1, which is rectangular in shape; and a vertical rod 6, which is fixedly installed on the side wall of the cold water tank 1 near the material feeding side. The vertical rod 6 is arranged vertically, with the bottom end of the vertical rod 6 located inside the tank body of the cold water tank 1 and the top end of the vertical rod 6 located above the cold water tank 1.
[0027] The first water-absorbing component 2 is rotatably mounted on the top of the upright 6; the second water-absorbing component 4 is rotatably mounted on the upright 6 and located below the first water-absorbing component 2. The second water-absorbing component 4 is located in the tank of the cold water tank 1. A water-absorbing gap is formed between the first water-absorbing component 2 and the second water-absorbing component 4, which is used to absorb water from the surface of the plastic strip by rotating the first water-absorbing component 2 and the second water-absorbing component 4. By simultaneously absorbing water from the surface of the plastic strip by the first water-absorbing component 2 and the second water-absorbing component 4, a large amount of water is quickly absorbed.
[0028] A connecting rod 7 is mounted on the upright rod 6; a first water-squeezing component 3 is slidably mounted on the connecting rod 7. By sliding the first water-squeezing component 3, the distance between the first water-squeezing component 3 and the first water-absorbing component 2 can be adjusted, thereby adjusting the squeezing interval as needed. The second water-squeezing component 5 and the first water-absorbing component 2 form a pressure zone squeezing through relative rotation, and the water adhering to the roller surface is squeezed out by using line pressure to realize the surface dehydration process.
[0029] The upright 6 is also equipped with a second water squeezing component 5, which forms a pressure zone between the second water squeezing component 5 and the second water absorption component 4 to squeeze out the water adhering to the roller surface and realize the surface dehydration process.
[0030] The first absorbent component 2 and the second absorbent component 4 are elastic, so they can be laid out synchronously according to the width or moisture content of the material. The first dewatering component 3 can independently adjust the gap with the first absorbent component 2 to flexibly meet the requirements of different material thicknesses or different water absorption strengths.
[0031] Preferably, the first squeezing member 3 is rotatably connected to the connecting rod 7, so that the first squeezing member 3 can rotate when it is squeezed against the first water-absorbing member 2. When rotating, the water on the surface of the first water-absorbing member 2 is squeezed and removed within the pressure zone, forming a uniform dehydration effect; the upright rod 6 is rotatably connected to the second squeezing member 5, so that the second squeezing member 5 rotates when it is squeezed against the second water-absorbing member 4. When rotating, the water on the surface of the second water-absorbing member 4 is squeezed and removed within the pressure zone, forming a uniform dehydration effect.
[0032] Preferably, one end of the connecting rod 7 is rotatably mounted on the upright 6 and fixed by bolts 14. When the angle needs to be adjusted, the bolts 14 are loosened for adjustment, and then tightened after adjustment. Bolts 14 are common fixing parts and can also be replaced with other parts for connection. The other end of the connecting rod 7 has a waist hole 8, and a slider 9 is slidably connected in the waist hole 8. The slider 9 is rotatably connected to the first water squeezing component 3. The slider 9 allows the first water squeezing component 3 to slide along the waist hole 8 of the connecting rod 7. The slider 9 is rotatably connected to a threaded rod 13. For example, a circular groove can be opened on the slider 9, and a bearing can be installed in the circular groove. The bearing is connected to the threaded rod 13 to achieve a rotatable connection. The threaded rod 13 passes through the connecting rod 7 and is threadedly connected to the connecting rod 7. Specifically, a threaded hole is opened in the middle of the end of the connecting rod 7 away from the upright 6 along the length direction of the connecting rod 7. The threaded hole is threadedly connected to the threaded rod 13. The other end of the threaded rod 13 is fixedly connected to a rotating block 10.
[0033] Preferably, the connecting rods 7 are arranged in two pieces along the width direction of the cold water tank 1 and are symmetrically distributed. Each connecting rod 7 is fixedly installed with a connecting block 11, and the connecting block 11 is located at the ends of the connecting rods 7 that are far apart from each other. A guide plate 12 is installed between the two connecting blocks 11. The guide plate 12 is located below the first water squeezing member 3 and is inclined from top to bottom toward the feeding end of the cold water tank 1, so that the water squeezed out by the first water suction member 2 and the first water squeezing member 3 can be guided into the cold water tank 1, avoiding water from flowing directly onto the second water suction member 4.
[0034] Preferably, the second dewatering component 5 can be slidably mounted on the upright 6. For example, the upright 6 can adopt a sliding design of the connecting rod 7 to realize the sliding of the second dewatering component 5.
[0035] As can be seen from the above description, this application adopts an independent adjustment method for the relative positions of the first water-squeezing component 3 and the first water-absorbing component 2. This is achieved through a cold water tank 1; a vertical rod 6, fixedly installed near the material discharge side of the cold water tank 1; a first water-absorbing component 2, rotatably installed on the top of the vertical rod 6; a second water-absorbing component 4, rotatably installed on the vertical rod 6 and located below the first water-absorbing component 2, forming a water-absorbing gap between the first water-absorbing component 2 and the second water-absorbing component 4; a connecting rod 7, disposed on the vertical rod 6; and a first water-squeezing component 3, slidably installed on the connecting rod 7, forming a pressure zone with the first water-absorbing component 2 through relative rotation. This allows for adjustment of the contact pressure and gap between the first water-absorbing component 2 and the first water-squeezing component 3 as needed, enabling real-time compensation for deviations caused by wear or changes in the diameter of the plastic strip, maintaining optimal squeezing conditions, ensuring continuous and efficient removal of surface moisture, avoiding residual moisture retention, and improving subsequent drying efficiency.
