Abstract
Description
Technical Field
[0001] This invention relates to a weather-resistant rubber and plastic sheet production apparatus and its production method, belonging to the field of rubber production technology. Background Technology
[0002] Rubber sheets, also known as rubber-plastic sheets, are sheet-like products with a certain thickness and large area, made primarily of rubber (which may contain reinforcing materials such as fabrics or thin metal sheets) through vulcanization. They are simply called rubber sheets. Rubber sheets have high hardness and generally moderate physical and mechanical properties. They can operate in air with low pressure and temperatures ranging from 20°C to +140°C. By adding additives with different properties and mixing them, different properties can be achieved. For example, weather-resistant rubber-plastic sheets can be made by adding PVC powder to nitrile rubber and mixing them in a mixer to form an alloy rubber, resulting in rubber-plastic sheet products with extremely high weather resistance.
[0003] The main production process is as follows: Nitrile rubber raw material is placed in a mixer and stirred and rolled to soften the raw material. After softening, PVC powder is added and mixed thoroughly to obtain a product with uniform properties. In order to improve the softening speed of the raw material and increase production efficiency during the mixing process, people have begun to consider heating it. However, the current heating method is relatively simple, directly heating the outside of the mixer box. However, the actual raw material has a considerable volume, and the external heating efficiency is low and the effect is not good. Moreover, the actual temperature uniformity is extremely poor, resulting in poor mixing effect and poor performance of the subsequently produced products.
[0004] Furthermore, in existing mixing machines, a power mechanism drives two sets of gears to rotate during startup. To improve the stability of gear meshing and reduce meshing friction, a sealed box is usually added, and lubricating oil is injected into the sealed box so that the gears are immersed in the lubricating oil. At the same time, this reduces the heat generated during rotation and absorbs the heat into the lubricating oil. However, during operation, the heat absorption capacity of the lubricating oil is limited. As it continuously absorbs heat and cools down, the overall temperature of the lubricating oil actually increases and its viscosity decreases. The lubrication and cooling effect on the meshing motion between gears decreases significantly. The lubricating oil is not effective for continuous operation, which in turn affects product quality and production efficiency.
[0005] In summary, there is an urgent need for a weather-resistant rubber and plastic sheet production device and its production method to solve the above problems and improve production efficiency and product performance. Summary of the Invention
[0006] The purpose of this invention is to overcome the above-mentioned deficiencies and provide a weather-resistant rubber and plastic sheet production apparatus and production method to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a weather-resistant rubber and plastic sheet production apparatus and its production method, comprising a base, a mounting seat fixedly installed on the top surface of the base, a mixing box fixedly connected to the top surface of the mounting seat, a rotating roller movably sleeved inside the mixing box, a mixing sleeve fixedly sleeved on the outer surface of the rotating roller, an intermediate plate fixedly sleeved inside the rotating roller, a heating tube fixedly installed on the side of the intermediate plate, a curved hole opened inside the rotating roller, an air inlet mechanism on the right side of the mixing box, a ventilation mechanism on the left side of the mixing box, and the inner... The mixing chamber has a preheating chamber, a feed inlet on the top surface of the mixing box, a pushing mechanism on the back of the base, a connecting shaft fixedly connected to the end face of the rotating roller, a first gear fixedly sleeved on the outer surface of the connecting shaft, a first seat and a second seat fixedly installed on the top surface of the base, both of which are movably sleeved with the connecting shaft, a power mechanism on the side of the first seat, a partition fixedly sleeved inside the mixing box, the partition movably sleeved with the rotating roller, and an air vent inside the mixing box, the inner and outer ends of which are connected to the preheating chamber and the feed inlet, respectively.
[0008] First embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, before feeding, the air pump in the air intake mechanism is started, and the heating pipe is activated, allowing air to enter the first frame through the air pipe in the air intake mechanism. From the first frame, the air enters the curved hole on the rotating roller, and the gas enters the inner cavity of the rotating roller. In the inner cavity, the heating pipe heats the air, causing the surface temperature of the rotating roller to rise. Simultaneously, the high-temperature gas enters the second frame of the ventilation mechanism through the curved hole on the other side, and then enters the through hole through the curved pipe in the ventilation mechanism. The high-temperature gas entering the through hole is then introduced into the preheating chamber, causing the temperature inside the mixing box and the box body to rise. After preheating, the raw materials are fed into the mixing box through the feed inlet, and the pushing mechanism is activated, causing the pusher plate to engage with the feed inlet. The power mechanism is activated, and the motor drives the rotating shaft to rotate. This causes the No. 2 gear on the outer surface of the shaft to drive the meshing No. 1 gear to rotate, thereby rotating the rotating roller to agitate and soften the material. The raw materials in the mixing box absorb heat from the inside and outside and quickly heat up and soften. The push plate is opened and additives are added. The push plate is kept sealed and agitation continues. After mixing is completed, the pushing mechanism is activated, causing the push plate to move slightly upward and open the vent hole. The sealing cover is also opened to increase the air intake pressure in the air intake mechanism. High-pressure air is then introduced into the mixing box through the ventilation mechanism and the vent hole on one side of the preheating chamber. The high-pressure gas introduced into the upper part of the mixing box continuously pushes the mixed product downward, causing the product to be extruded along the discharge port by the air pressure, completing the rapid discharge.
[0009] First, by utilizing the air pump in the air intake mechanism to provide incoming air, and in conjunction with the curved holes on the No. 1 frame and the rotating roller, air is ensured to enter the inner cavity of the rotating roller while it is rotating. The air is heated in the inner cavity through the heating tube, and the heated air raises the surface temperature of the rotating roller from the inside. In conjunction with the side ventilation mechanism, the heated air is introduced into the preheating chamber, achieving temperature rise on both the inside and outside of the mixing box before the raw materials are added, thus improving the preheating effect. After the raw materials are added, the raw materials are heated from both the inside and outside through the internal rotating roller and the preheating chamber in the inner wall of the upper mixing box, greatly improving the heating efficiency, thereby improving the stirring and softening efficiency and achieving an increase in production efficiency.
[0010] Furthermore, by utilizing the up-and-down movement of the push plate, after the mixing is completed, the push plate is moved upward and the air outlet is opened. While maintaining the pressure valve seal and increasing the air inlet pressure, the air inlet mechanism introduces high-pressure gas into the upper part of the mixing box through the ventilation mechanism and the preheating chamber. With the sealing cover open, the high-pressure gas above continuously squeezes the internal product, squeezing the mixed product out of the mixing box. The air inlet mechanism is reused to achieve quick discharge of the mixed product from the mixing box, making it convenient to use.
[0011] Preferably, the air intake mechanism includes a first frame, an air pump, and an air pipe. The first frame is fixedly connected to the right end face of the mixing box and movably sleeved with the rotating roller. The air pump is fixedly installed on the top surface of the base. The air pipe is fixedly connected between the first frame and the air pump. By using the air pump to provide incoming air, the gas is introduced into the first frame in conjunction with the air pipe. The air gathered in the first frame enters through one end of the curved hole on the surface of the rotating roller, thereby being introduced into the inner cavity of the rotating roller, realizing the supply of room temperature air.
[0012] Preferably, the ventilation mechanism includes a second frame and a curved pipe. The second frame is fixedly connected to the left end of the mixing box and movably sleeved with the rotating roller. The curved pipe is fixedly connected to the top surface of the second frame. By utilizing the second frame in the ventilation mechanism, hot air flowing out of the curved hole on the other side is gathered inside and then passed into the through hole through the curved pipe, thus realizing the export of hot air.
[0013] Preferably, the mixing box has a through hole inside, and the inner and outer ends of the through hole are connected to the preheating chamber and the curved pipe, respectively. Hot air is introduced into the preheating chamber through the ventilation mechanism via the through hole, and the preheating chamber heats the top shell of the mixing box. Combined with the increased temperature of the rotating roller surface, the interior and upper part of the mixing box are preheated, which increases the heating speed of the raw materials and ensures that the raw materials are heated from the top and the interior at the same time when they enter and heat up, thereby improving the softening efficiency and thus improving the production and processing efficiency.
[0014] Preferably, the top surface of the mixing box is provided with an installation hole, and a pressure valve is provided inside the installation hole. The pressure valve in the installation hole controls the final flow direction of hot air. During operation, the valve is opened to allow hot air to be discharged after heat exchange, and is closed after the push plate moves up slightly, so as to ensure that the high-pressure gas temperature enters the mixing box and realizes the pressure extrusion of the product.
[0015] Preferably, the pushing mechanism includes a fixed frame, a lifting rod, and a push plate. The fixed frame is fixedly installed on the back of the base, the lifting rod is fixedly installed on the top surface of the inner surface of the fixed frame, and the push plate is fixedly connected to the lower end of the lifting rod. The outer surface of the push plate is movably sleeved with the feed inlet. The pushing mechanism is used to assist in pressing in the raw material after it is fed in and to seal the feed inlet. The position of the push plate and the opening and closing of the pressure valve control the final flow direction of the air.
[0016] Preferably, the power mechanism includes a motor frame, a motor, a rotating shaft, a second gear, and blades. The motor frame is fixedly installed on the outer side of the first seat, the motor is fixedly installed inside the motor frame, the rotating shaft is fixedly connected to the output shaft of the motor, the second gear is fixedly sleeved on the outer surface of the rotating shaft and meshes with the first gear, and the blades are fixedly sleeved on the outer surface of the rotating shaft. By using the motor in the power mechanism to provide power, and cooperating with the meshing of the first and second gears, the mixing box is operated, and by using the rotating shaft to drive the blades to rotate, the surface of the fixed box is cooled.
[0017] Preferably, a fixed box is fixedly installed on the top surface of the base. The sides of the fixed box are movably connected to the connecting shaft and the rotating shaft, respectively. The fixed box is located outside the first gear and the second gear. By utilizing the fixed box and the lubricating oil introduced inside, the first gear and the second gear immersed in the lubricating oil have good lubrication and meshing effects, thereby achieving heat absorption and noise reduction.
[0018] Preferably, the mixing box has a discharge port on the front, and a sealing cover is movably installed on the inner surface of the discharge port. A guide frame located outside the sealing cover is fixedly connected to the front of the mixing box. The discharge port is sealed by the sealing cover, and the guide frame facilitates the discharge of the extruded product.
[0019] Second embodiment: as follows Figure 1 , Figure 2 and Figure 3As shown, during continuous operation, as gears one and two in the fixed housing mesh and rotate, the lubricating oil flowing into the fixed housing gradually absorbs heat and rises in temperature. As the lubricating oil heats up, its viscosity gradually decreases, weakening the lubrication of gears one and two. Furthermore, as the shaft in the power mechanism rotates rapidly, the blades on the outer surface of the shaft rotate rapidly, causing the blades to blow air towards the side of the fixed housing, thus lowering the surface temperature of the fixed housing. Consequently, the lubricating oil, after its internal heating, exchanges heat with the fixed housing, causing the internal lubricating oil temperature to decrease and recover, and its viscosity to return to a stable level.
[0020] First, blades are fixedly attached to the outer surface of the shaft of the power mechanism, with the blades facing the fixed box. During continuous long-term operation, the blades continuously blow air towards the fixed box, which lowers the surface temperature of the fixed box. Under continuous operation, the lubricating oil in the fixed box exchanges heat with the fixed box, thereby reducing the temperature of the lubricating oil. This prevents the lubricating oil from losing viscosity after absorbing the temperature from the meshing rotation of gears one and two, ensuring that the lubricating oil in the fixed box has a stable lubrication effect and good performance.
[0021] The equipment and method for producing weather-resistant rubber and plastic sheets include the following operating steps:
[0022] Step 1: Before feeding, start the air pump in the air intake mechanism and start the heating pipe so that the air enters the interior of the rotating roller through the curved hole, is heated by the heating pipe and then delivered to the ventilation mechanism, and is introduced into the preheating chamber through the through hole so that the interior of the mixing box has an initial preheating temperature.
[0023] Step 2: Feed the raw materials into the mixing box through the feed inlet and start the pushing mechanism so that the push plate is fitted into the feed inlet. Start the power mechanism so that the two sets of rotating rollers rotate. The raw materials are stirred in the mixing box. The raw materials in the mixing box absorb heat from the inside and outside and quickly heat up and soften. Open the push plate and add the additives. Keep the push plate sealed and continue stirring.
[0024] Step 3: After mixing, start the pushing mechanism to move the push plate slightly upward and open the vent. Open the sealing cover and increase the air pressure in the air intake mechanism. This allows high-pressure air to enter the mixing box through the ventilation mechanism and the vent on one side of the preheating chamber. The high-pressure gas in the upper part of the mixing box continuously pushes the mixed product downward, causing the product to be squeezed out along the outlet by the air pressure.
[0025] Step 4: During continuous operation, the shaft in the power mechanism rotates rapidly, which causes the blades on the outer surface of the shaft to rotate rapidly. This causes the blades to blow air towards the side of the fixed box, which lowers the surface temperature of the fixed box. As a result, the internally heated lubricating oil exchanges heat with the fixed box, which lowers the internal lubricating oil temperature and keeps the viscosity stable.
[0026] The beneficial effects of this invention are as follows:
[0027] 1. This invention utilizes an air pump in the air intake mechanism to provide incoming air, and in conjunction with the curved holes on the first frame and the rotating roller, ensures that air is introduced into the inner cavity of the rotating roller while it is rotating. The air is heated in the inner cavity through a heating tube, and the heated air raises the surface temperature of the rotating roller from the inside. In conjunction with the side ventilation mechanism, the heated air is introduced into the preheating chamber. This achieves temperature rise on both the inside and outside of the mixing box before the raw materials are added, improving the preheating effect. After the raw materials are added, the raw materials are heated from both the inside and outside through the internal rotating roller and the preheating chamber in the upper inner wall of the mixing box, greatly improving the heating efficiency, thereby improving the stirring and softening efficiency and increasing production efficiency.
[0028] 2. This invention utilizes the up-and-down movement of a pusher plate. After mixing is completed, the pusher plate is moved upward and the vent is opened. While maintaining the pressure valve seal and increasing the inlet pressure, the inlet mechanism introduces high-pressure gas into the upper part of the mixing chamber through the ventilation mechanism and the preheating chamber. With the sealing cover open, the high-pressure gas above continuously squeezes the product inside, extruding the mixed product from the mixing chamber. The inlet mechanism is reused to achieve rapid discharge of the mixed product from the mixing chamber, making it convenient to use.
[0029] 3. This invention fixes blades to the outer surface of the rotating shaft of the power mechanism, with the blades facing the fixed box. During continuous long-term operation, the blades continuously blow air towards the fixed box, reducing the surface temperature of the fixed box. Under continuous operation, the lubricating oil in the fixed box exchanges heat with the fixed box, thereby reducing the lubricating oil temperature. This prevents the lubricating oil from losing viscosity after absorbing the temperature from the meshing rotation of the first and second gears, ensuring that the lubricating oil in the fixed box has a stable lubrication effect and good performance.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0038] like Figures 1 to 6 As shown, this embodiment of the invention provides a weather-resistant rubber and plastic sheet production apparatus and its production method, including a base 1, a mounting seat 2 fixedly installed on the top surface of the base 1, a mixing box 3 fixedly connected to the top surface of the mounting seat 2, a rotating roller 8 movably sleeved inside the mixing box 3, a mixing sleeve 9 fixedly sleeved on the outer surface of the rotating roller 8, an intermediate plate 13 fixedly sleeved inside the rotating roller 8, a heating pipe 14 fixedly installed on the side of the intermediate plate 13, a curved hole 11 opened inside the rotating roller 8, an air inlet mechanism 15 provided on the right side of the mixing box 3, a ventilation mechanism 16 provided on the left side of the mixing box 3, and a preheating chamber 1 inside the mixing box 3. 7. The top surface of the mixing box 3 is provided with a feed inlet 12. The back of the base 1 is provided with a pushing mechanism 4. The end face of the rotating roller 8 is fixedly connected to a connecting shaft 7. A first gear 23 is fixedly sleeved on the outer surface of the connecting shaft 7. A first seat 5 and a second seat 6 are fixedly installed on the top surface of the base 1. Both the first seat 5 and the second seat 6 are movably sleeved with the connecting shaft 7. A power mechanism 24 is provided on the side of the first seat 5. A partition 10 is fixedly sleeved inside the mixing box 3. The partition 10 is movably sleeved with the rotating roller 8. An air outlet 26 is provided inside the mixing box 3. The inner and outer ends of the air outlet 26 are connected to the preheating chamber 17 and the feed inlet 12, respectively.
[0039] First embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, before feeding, the air pump 152 in the air intake mechanism 15 is started, and the heating pipe 14 is activated, so that the air enters the first frame 151 through the air pipe 153 in the air intake mechanism 15, and then enters the curved hole 11 on the rotating roller 8 through the first frame 151. The air then enters the inner cavity of the rotating roller 8 and is heated by the heating pipe 14. The heated air causes the surface temperature of the rotating roller 8 to rise. At the same time, the high-temperature gas enters the second frame 161 of the ventilation mechanism 16 through the curved hole 11 on the other side, and then enters the through hole 18 through the curved pipe 162 in the ventilation mechanism 16. The high-temperature gas entering the through hole 18 is then introduced into the preheating chamber 17, causing the temperature inside the mixing box 3 and the box body to rise. After preheating, the raw materials are fed into the interior of the mixing box 3 through the feed port 12, and the pushing mechanism 4 is activated, so that the push plate 43 is sleeved on the In the feed inlet 12, the power mechanism 24 is started, and the motor 242 drives the rotating shaft 243 to rotate, which causes the second gear 244 on the outer surface of the rotating shaft 243 to drive the meshing first gear 23 to rotate, thereby causing the rotating roller 8 to rotate, and the material is stirred and softened. The raw materials in the mixing box 3 absorb heat from the inside and outside and are quickly heated and softened. The push plate 43 is opened and the additives are added. The push plate 43 is kept sealed and stirring continues. When the mixing is completed, the pushing mechanism 4 is started, which causes the push plate 43 to move slightly upward and open the vent 26. The sealing cover 21 is opened, and the air pressure in the air intake mechanism 15 is increased, so that high-pressure air is introduced into the mixing box 3 through the ventilation mechanism 16 and the vent 26 on one side of the preheating chamber 17. The high-pressure gas introduced into the upper part of the mixing box 3 continuously pushes the mixed product downward, so that the product is pushed by the air pressure and squeezed out along the discharge port 20, completing the quick discharge.
[0040] First, by using the air pump 152 in the air intake mechanism 15 to provide incoming air, and in conjunction with the first frame 151 and the curved hole 11 on the rotating roller 8, air is ensured to be introduced into the inner cavity of the rotating roller 8 while it is rotating. The air is heated in the inner cavity through the heating tube 14. The heated air is used to raise the surface temperature of the rotating roller 8 from the inside. In conjunction with the ventilation mechanism 16 on the side, the heated air is introduced into the preheating chamber 17. Before the raw materials are added, the inner and outer sides of the mixing box 3 are heated, which improves the preheating effect. After the raw materials are added, the raw materials are heated from both the inside and outside through the inner rotating roller 8 and the preheating chamber 17 in the inner wall of the upper mixing box 3. This greatly improves the heating efficiency, thereby improving the stirring and softening efficiency and increasing the production efficiency.
[0041] Furthermore, by utilizing the up-and-down movement of the push plate 43, after the mixing is completed, the push plate 43 is moved upward and the air outlet 26 is opened. While keeping the pressure valve 19 sealed and increasing the air inlet pressure, the air inlet mechanism 15 introduces high-pressure gas into the upper part of the mixing box 3 through the ventilation mechanism 16 and the preheating chamber 17. With the sealing cover 21 open, the high-pressure gas above continuously squeezes the internal product, squeezing the mixed product out of the mixing box 3. The air inlet mechanism 15 is used again to achieve quick discharge of the mixed product from the mixing box 3, making it convenient to use.
[0042] The air intake mechanism 15 includes a first frame 151, an air pump 152, and an air pipe 153. The first frame 151 is fixedly connected to the right end face of the mixing box 3 and is movably sleeved with the rotating roller 8. The air pump 152 is fixedly installed on the top surface of the base 1. The air pipe 153 is fixedly connected between the first frame 151 and the air pump 152. By using the air pump 152 to provide incoming air, the air is introduced into the first frame 151 in conjunction with the air pipe 153. The air gathered in the first frame 151 enters through one end of the curved hole 11 on the surface of the rotating roller 8, thereby introducing it into the inner cavity of the rotating roller 8, realizing the supply of room temperature air.
[0043] The ventilation mechanism 16 includes a second frame 161 and a curved pipe 162. The second frame 161 is fixedly connected to the left end of the mixing box 3 and is movably connected to the rotating roller 8. The curved pipe 162 is fixedly connected to the top surface of the second frame 161. By utilizing the second frame 161 in the ventilation mechanism 16, the hot air flowing out of the curved hole 11 on the other side is gathered inside and then introduced into the through hole 18 through the curved pipe 162, so as to realize the export of hot air.
[0044] The mixing box 3 has a through hole 18 inside. The inner and outer ends of the through hole 18 are connected to the preheating chamber 17 and the curved pipe 162, respectively. Hot air is introduced into the preheating chamber 17 from the ventilation mechanism 16 through the through hole 18. The preheating chamber 17 heats the top shell of the mixing box 3. Combined with the increased temperature of the rotating roller 8, the interior and upper part of the mixing box 3 are preheated. This increases the heating speed of the raw materials and ensures that the raw materials are heated from the top and the interior at the same time when they enter and heat up, thereby improving the softening efficiency and thus improving the production and processing efficiency.
[0045] The top surface of the mixing box 3 is provided with an installation hole 27, and a pressure valve 19 is provided inside the installation hole 27. The pressure valve 19 in the installation hole 27 controls the final flow direction of the hot air. During operation, it is opened to allow the hot air to be discharged after heat exchange, and it is closed after the push plate 43 moves up slightly, so as to ensure that the high-pressure gas temperature enters the interior of the mixing box 3 and realizes the pressure extrusion of the product.
[0046] The feeding mechanism 4 includes a fixed frame 41, a lifting rod 42, and a push plate 43. The fixed frame 41 is fixedly installed on the back of the base 1. The lifting rod 42 is fixedly installed on the top surface of the inner surface of the fixed frame 41. The push plate 43 is fixedly connected to the lower end of the lifting rod 42. The outer surface of the push plate 43 is movably sleeved with the feed inlet 12. The feeding mechanism 4 is used to assist in pressing in the raw materials after they are put in and to seal the feed inlet 12. The position of the push plate 43 and the opening and closing of the pressure valve 19 are used to control the final flow direction of the air.
[0047] The power mechanism 24 includes a motor frame 241, a motor 242, a rotating shaft 243, a second gear 244, and a blade 245. The motor frame 241 is fixedly installed on the outer side of the first seat 5, the motor 242 is fixedly installed inside the motor frame 241, the rotating shaft 243 is fixedly connected to the output shaft of the motor 242, the second gear 244 is fixedly sleeved on the outer surface of the rotating shaft 243 and meshes with the first gear 23, and the blade 245 is fixedly sleeved on the outer surface of the rotating shaft 243. By using the motor 242 in the power mechanism 24 to provide power, and cooperating with the meshing of the first gear 23 and the second gear 244, the mixing box 3 is operated, and by using the rotating shaft 243 to drive the blade 245 to rotate, the surface of the fixed box 25 is cooled.
[0048] The base 1 has a fixed box 25 fixedly installed on its top surface. The sides of the fixed box 25 are movably connected to the connecting shaft 7 and the rotating shaft 243 respectively. The fixed box 25 is located outside the first gear 23 and the second gear 244. By utilizing the fixed box 25 and the lubricating oil inside, the first gear 23 and the second gear 244 immersed in the lubricating oil have good lubrication and meshing effects, achieving heat absorption and noise reduction.
[0049] The mixing box 3 has a discharge port 20 on its front side. A sealing cover 21 is movably installed on the inner surface of the discharge port 20. A guide frame 22 located outside the sealing cover 21 is fixedly connected to the front side of the mixing box 3. The discharge port 20 is sealed by the sealing cover 21, and the guide frame 22 facilitates the discharge of the extruded product.
[0050] Second embodiment: as follows Figure 1 , Figure 2 and Figure 3As shown, during continuous operation, as gears 23 and 244 in the fixed housing 25 continuously mesh and rotate, the lubricating oil flowing into the fixed housing 25 gradually absorbs heat and rises in temperature. As the lubricating oil heats up, its viscosity gradually decreases, weakening the lubrication of gears 23 and 244. Furthermore, as the shaft 243 in the power mechanism 24 rotates rapidly, the blades 245 on the outer surface of the shaft 243 rotate rapidly, causing the blades 245 to blow air towards the side of the fixed housing 25. This lowers the surface temperature of the fixed housing 25, allowing the internally heated lubricating oil to exchange heat with the fixed housing 25, causing the internal lubricating oil temperature to drop and recover, and its viscosity to return to and remain stable.
[0051] First, by fixing blades 245 onto the outer surface of the rotating shaft 243 of the power mechanism 24 and making the blades 245 face the fixed box 25, during continuous long-term operation, the blades 245 continuously blow air towards the fixed box 25, causing the surface temperature of the fixed box 25 to decrease. Under continuous operation, the lubricating oil in the fixed box 25 exchanges heat with the fixed box 25, thereby reducing the lubricating oil temperature. This prevents the lubricating oil from absorbing the temperature of the meshing rotation of the first gear 23 and the second gear 244, thus ensuring that the lubricating oil in the fixed box 25 has a stable lubrication effect and good performance.
[0052] The equipment and method for producing weather-resistant rubber and plastic sheets include the following operating steps:
[0053] Step 1: Before feeding, start the air pump 152 in the air intake mechanism 15 and start the heating pipe 14 so that the air enters the interior of the rotating roller 8 through the curved hole 11, and is heated by the heating pipe 14 and then transported to the ventilation mechanism 16, and is introduced into the preheating chamber 17 through the through hole 18 so that the interior of the mixing box 3 has an initial preheating temperature.
[0054] Step 2: The raw materials are fed into the mixing box 3 through the feed inlet 12, and the pushing mechanism 4 is started so that the push plate 43 is fitted into the feed inlet 12. The power mechanism 24 is started so that the two sets of rotating rollers 8 rotate. The raw materials are stirred in the mixing box 3. The raw materials in the mixing box 3 absorb heat from the inside and outside and quickly heat up and soften. The push plate 43 is opened and the additives are added. The push plate 43 is kept sealed and stirring continues.
[0055] Step 3: After mixing is completed, start the pushing mechanism 4, so that the push plate 43 moves up slightly and opens the air outlet 26, and open the sealing cover 21 to increase the air intake pressure in the air intake mechanism 15, so that high pressure air is introduced into the mixing box 3 through the ventilation mechanism 16 and the air outlet 26 on one side of the preheating chamber 17. The high pressure gas introduced into the upper part of the mixing box 3 continuously pushes the mixed product downward, so that the product is pushed by the air pressure and squeezed out along the outlet 20.
[0056] Step 4: During continuous operation, the shaft 243 in the power mechanism 24 rotates rapidly, which causes the blades 245 on the outer surface of the shaft 243 to rotate rapidly. This causes the blades 245 to blow air toward the side of the fixed box 25, which lowers the surface temperature of the fixed box 25. As a result, the lubricating oil that has been heated inside exchanges heat with the fixed box 25, which lowers the internal lubricating oil temperature and keeps the viscosity stable.
