Description

Technical Field

[0001] The invention belongs to the technical field of plastic masterbatch processing equipment, and in particular relates to a device and method for preparing ultraviolet-resistant plastic masterbatch. Background Art

[0002] UV-resistant plastic masterbatch is a plastic colorant with UV resistance, which is widely used in the production of plastic products, especially in outdoor products, auto parts, building materials and other fields that need to be exposed to the sun for a long time. The harm of ultraviolet (UV) light to plastics is mainly manifested in that it can accelerate the aging of plastics, causing the color of plastics to fade, become brittle, crack and other problems. In order to solve this problem, UV-resistant plastic masterbatch came into being. It improves the weather resistance and service life of plastics by adding UV absorbers or UV stabilizers.

[0003] In the prior art, a patent with publication number "CN216708314U" discloses a cooling device for a plastic masterbatch production line. The cooperation between the liquid pump and the refrigerator keeps the cooling water inside the box at a low temperature at all times, thereby having a good cooling effect on the masterbatch plastic strips. The setting of the filtering device can reduce the impurities in the cooling water inside the box, thereby improving the cooling quality and avoiding excessive impurities in the masterbatch plastic strips. At the same time, it is easy to clean itself and will not affect the filtering effect. The setting of the driving device can facilitate the user to take and place the masterbatch plastic strips, reduce the labor of the user, improve the cooling efficiency, and solve the problem that the cooling device of the previous plastic masterbatch production line is not easy to take and does not have a filtering function.

[0004] However, the above device still has the following problems during implementation: when water is pumped into the refrigerator for cooling through a liquid pump, the specific heat capacity of water is large, which makes the cooling speed of the refrigerator relatively slow, and the water flow needs to keep flowing on the surface of the masterbatch plastic strip, which places high requirements on the load of the refrigerator, and it is easy for the cooling water temperature to be high in one section and low in another, which greatly affects the molding of the masterbatch plastic strip.

[0005] To this end, we provide a device and method for preparing UV-resistant plastic masterbatch to solve the above problems. Summary of the invention

[0009] The present invention is further configured such that the air cooling component further comprises a movable shaft, the movable shaft is movably connected to the interior of the conversion shell, and turbine blades are fixedly connected to the surface of the movable shaft.

[0010] The present invention is further configured such that one end of the movable shaft passes through the outside of the conversion shell and is fixedly connected to a first pulley, a second pulley is fixedly connected to the surface of the rotating shaft, and a conveying belt is sleeved between the first pulley and the second pulley.

[0011] The present invention is further configured such that a drainage hole is provided inside the spray rack, and the top of the spray pipe is connected to the conversion shell.

[0012] The present invention is further configured such that a water inlet at the bottom of the booster pump is connected to a water suction pipe, and the booster pump is connected to the conversion shell through a pipeline.

[0013] The present invention is further configured such that the surface of the rotating shaft is movably connected to a fixing plate via a bearing, and the top of the fixing plate is fixedly connected to the vertical plate.

[0014] The present invention is further configured such that a rotating shell is movably connected inside the water tank, a filter shell is fixedly connected to one end of the rotating shell, and a first gear is fixedly connected to the surface of the rotating shell.

[0015] The present invention is further configured such that a driving motor is fixedly connected to one side of the water tank, a second gear is fixedly connected to an output end of the driving motor, and the first gear is meshed with the second gear.

[0016] The present invention is further configured such that a fixed shaft is movably connected inside the rotating shell, the other end of the fixed shaft is fixedly connected to a water tank, a brush plate is fixedly connected to the surface of the fixed shaft, a collecting box is provided inside the water tank, and a water guide plate is fixedly connected to the bottom of the rotating shell.

[0017] A method for preparing a UV-resistant plastic masterbatch preparation device comprises the following steps.

[0018] S1: When the masterbatch rubber strip is transported through the conveying shell, the cooling water in the conveying shell can be used to cool the masterbatch rubber strip. At the same time, the pressure pump can be started through the external controller. The pressure pump cooperates with the suction pipe to draw the water flow in the water storage tank into the conversion shell, and transports it to the conveying shell through the water inlet pipe to accelerate the flow of water inside the conveying shell. When the water level inside the conveying shell rises, it can be discharged back to the water storage tank through the drainage shell.

[0019] S2: When the water flows through the conversion shell and the spray pipe and enters the spray rack, it can be discharged through the drainage hole. The discharged water flows along the guide blades to increase the contact area between the water and the air. The evaporation of the water can be used to absorb heat and accelerate the cooling efficiency of the water.

[0020] S3: When the water flow is pumped into the conversion shell through the pressure pump and discharged into the conversion shell through the drainage shell, the flow of the water flow can be used to drive the turbine blades to rotate. The turbine blades cooperate with the movable shaft to drive the first pulley to rotate. The first pulley cooperates with the conveying belt to drive the second pulley to rotate. The second pulley cooperates with the rotating shaft to drive the fan blades to rotate. The fan blades drive the air to blow to the guide blades, thereby accelerating the volatilization efficiency of the water and improving the cooling effect of the cooling water.

[0021] S4: When water flows through the spray rack and drips into the filter shell, the filter shell can be used to filter impurities in the cooling water. When impurities accumulate inside the filter shell, the drive motor can be started. The drive motor cooperates with the second gear to drive the first gear to rotate. The first gear cooperates with the rotating shell to drive the filter shell to rotate. At this time, the position of the brush plate remains unchanged. When the rotating shell rotates 180 degrees counterclockwise, the brush plate can be used to clean the impurities inside the filter shell.

[0022] The present invention has the following beneficial effects.

[0023] 1. The present invention can use a pressure pump to extract the water flow inside the water tank through the setting of the circulation component, and then discharge it into the conveying shell. During the conveying process of the masterbatch rubber strip, it can be completely immersed in the water flow, and the heat of the masterbatch rubber strip is transferred by the water flow to achieve the effect of conduction cooling. At the same time, the water flow can be discharged back to the water tank through the drainage shell to achieve the effect of circulation.

[0024] 2. The present invention, through the setting of the cooling component, can divert and discharge the water flow through the spray pipe during the water circulation process. The discharged water flow slowly descends along the guide blades, which can increase the water drainage area of ​​the water flow, so that the air can fully contact the water flow. The effect of water evaporation and heat absorption can be used to reduce the temperature during the water circulation process, thereby achieving a rapid cooling effect.

[0025] 3. Through the setting of the air cooling component, the present invention can utilize the water flow generated by water delivery and discharge to drive the turbine blades to rotate. When the turbine blades rotate, kinetic energy can be generated, and the first pulley and the second pulley can be used to transmit the kinetic energy of the water, thereby driving the fan blades to rotate. When the fan blades rotate, the flow of air can be accelerated, thereby increasing the cooling efficiency of the water flow.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
