Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a plastic strip cooling device for processing plastic granules. Background Technology

[0002] In the production of plastic granules, plastic raw materials are typically plasticized and melted using a screw extruder, then extruded into strips or ribbons through a die. These strips are then cut into granules by granulation equipment. The extruded plastic strips need to be cooled and shaped promptly to ensure the smooth progress of subsequent pelletizing processes and the quality of the granules. For example, if cooling is not timely or uniform, the plastic strips will deform under gravity, or internal stress may be generated due to excessively fast or slow cooling, affecting the appearance and physical properties of the plastic granules. With the development of the plastic granule processing industry, the requirements for production efficiency and product quality are constantly increasing. Traditional cooling methods may suffer from slow cooling speed, low efficiency, and uneven cooling, failing to meet the needs of large-scale, high-quality production. Therefore, it is necessary to develop specialized cooling devices to achieve rapid and uniform cooling, improve production efficiency, and reduce scrap rates.

[0003] In existing technology, water is drawn from a water tank by a spraying component and sprayed onto a plastic strip through a nozzle. The plastic strip is first cooled by being wetted by the spraying component, and then immersed in water for a second cooling by passing through the spiral ladder inside the spiral platform component. This can greatly improve the cooling efficiency. When the plastic strip leaves the spiral platform component, it drives the spiral ladder to rotate, which can also make the water in the water tank dissipate heat evenly, further improving the cooling effect.

[0004] However, when using spray components for cooling, the sprayed water can only remove some of the heat from the surface of the plastic strip when it comes into contact with it. The heat inside the plastic strip needs to be gradually conducted to the surface and then carried away by the water. If the plastic strip is thick or has poor thermal conductivity, the speed at which the internal heat is conducted to the surface is slow. Relying solely on the evaporation of sprayed water on the surface to dissipate heat is insufficient to cool the entire plastic strip quickly, leading to the accumulation of internal heat and failing to meet the cooling requirements. Utility Model Content

[0005] The purpose of this invention is to provide a plastic strip cooling device for processing plastic granules, which solves the problem that in the prior art, the sprayed water can only remove part of the heat from the surface of the plastic strip, and if the plastic strip is thick or has poor thermal conductivity, it cannot meet the cooling requirements.

[0006] To achieve the above objectives, this utility model provides a plastic strip cooling device for processing plastic granules, including a mounting block. A water filling groove is provided in the middle of the top surface of the mounting block. Mounting plates are fixedly connected to the front and rear ends of the top left side of the mounting block. A support plate is fixedly connected to the front right end of the mounting block. A cooling mechanism is provided on the top of the mounting block for cooling the extruded plastic strip. A dustproof mechanism is provided on the right side of the mounting block for preventing external dust from contaminating the plastic strip.

[0007] The cooling mechanism includes a fan, the bottom of which is fixedly connected to the top of a support plate. A rotating shaft is fixedly connected between two adjacent mounting plates. An electric conveying roller is rotatably connected to the outer wall of the rotating shaft. A high-speed transmission component is provided on the left side of the middle of the inner wall of the water filling tank, and a low-speed transmission component is provided on the right side of the inner wall of the water filling tank. The high-speed transmission component and the low-speed transmission component are arranged crosswise. A ventilation component is provided on the rear side of the fan. An extrusion component is provided on the top left side of the mounting block near the edge.

[0008] The dustproof mechanism includes a U-shaped cover, the bottom of which is fixedly connected to the top right side of the mounting block, and an inclined plate fixedly connected to the left side of the U-shaped cover. A transmission groove is provided in the middle of the right side of the top surface of the mounting block. A filter assembly is provided on the left side of the fan, and a collection assembly is provided on the right side of the mounting block.

[0009] The extrusion assembly includes an extruder, the bottom of which is fixedly connected to the top left side of the mounting block near the edge, and an extrusion hole is provided on the right side of the extruder.

[0010] The high-speed transmission assembly includes a second rotating shaft, the front and rear ends of which are fixedly connected to the left side of the inner wall of the water filling tank, and an electric conveying roller is rotatably connected to the outer wall of the second rotating shaft.

[0011] The low-speed transmission component includes a rotating shaft three, the front and rear ends of which are fixedly connected to the right side of the inner wall of the water filling tank, and an electric conveying roller three is rotatably connected to the outer wall of the rotating shaft three.

[0012] The ventilation assembly includes a ventilation duct, the rear side of which is connected to the front side of the fan. The left and right ends of the rear side of the ventilation duct are connected to branch pipes, and the outer wall of the branch pipe has multiple air outlets.

[0013] The filter assembly includes an air inlet pipe, the right side of which is connected to the left side of the fan. A dust filter plate is fixedly connected to the middle of the inner wall of the air inlet pipe, and a filter screen is fixedly connected to the left side of the inner wall of the air inlet pipe.

[0014] The collection component includes a collection box, the left side of which is fixedly connected to the right side of the mounting block, and a feed inlet is provided on the top left side of the collection box.

[0015] This utility model discloses a plastic strip cooling device for processing plastic granules. The extruder extrudes plastic through the extrusion orifice. The electric conveyor roller one is started to send the plastic into a water tank filled with cooling water. After being cooled in the water tank, the plastic is conveyed by the electric conveyor roller three. Due to the different height between the three and the electric conveyor roller two, the plastic is stretched to increase the contact area with the cooling water. Finally, the plastic is transferred to the transmission groove. The fan draws in air and discharges it from the ventilation pipe. The air is sprayed out from the air outlet through the branch pipe, which can reduce the thickness of the plastic and thus allow the interior of the plastic to be fully cooled, improving the cooling efficiency.

[0016] After the fan starts, air is drawn in through the intake pipe, passes through the filter to remove large particles and dust, and then clean air is discharged. The U-shaped cover and inclined plate prevent impurities from falling into the plastic. After cooling and drying, the plastic enters the collection box through the feed inlet, which realizes dust prevention and collection of the plastic, reduces the entry of impurities, and thus improves the purity of the plastic.

[0036] Working principle: Extruder 2041 extrudes plastic from extrusion hole 2042, which in turn activates electric conveyor roller 203. Electric conveyor roller 203 conveys the extruded plastic to the interior of water tank 4, which is filled with cooling water. When the plastic enters the interior of water tank 4, it is cooled by the cooling water. The plastic is then conveyed by electric conveyor roller 2062. Since electric conveyor roller 2062 and electric conveyor roller 2052 are at different heights, the plastic is pulled by the two conveyor rollers, thereby increasing the contact area between the plastic and the cooling water. Finally, after the plastic is conveyed to transmission groove 303, fan 201 is activated. Fan 201 draws in outside air and exhausts it through ventilation pipe 2071. After entering ventilation pipe 2071, the air is dispersed into branch pipe 2072 and finally sprayed out from air outlet 2073. This reduces the thickness of the plastic, thereby allowing the interior of the plastic to be fully cooled, improving the cooling efficiency.

[0037] When the fan 201 starts, it draws in outside air through the intake pipe 3041. The air first passes through the filter screen 3043, which blocks larger particles in the air. After passing through the filter screen 3043, the air is filtered out of dust. Finally, the filtered air is discharged. The U-shaped cover 301 and the inclined plate 302 prevent impurities in the outside air from falling onto the plastic. Finally, the cooled and dried plastic enters the collection box 3051 through the feed port 3052, achieving dust prevention and collection of the plastic, reducing the entry of impurities, and thus improving the purity of the plastic.
