Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to an extruder protection device. Background Technology

[0002] A blown film machine requires heating the extruder to melt the material and extrude the film from the die. When the extruder heats the material, the extrusion barrel will be heated. To prevent operators from accidentally coming into direct contact with the extrusion barrel and getting burned, a heat shield is usually installed on the outer periphery of the extrusion mechanism for protection.

[0003] Chinese utility model patent publication number "CN206812416U" discloses an extruder anti-scalding protective cover, including a left side plate, a left side upper plate, a right side upper plate, and a right side plate. The left side plate and the left side upper plate, and the right side upper plate and the right side plate are respectively connected by at least one movable connecting device. The left side upper plate or the right side upper plate is provided with at least one self-locking clip for connecting and fixing the two together. The bottom of the left side plate is connected to at least one first fixing device for fixing the extruder anti-scalding protective cover to the extruder through a first sliding connecting device. The bottom of the right side plate is connected to at least one second fixing device for fixing the extruder anti-scalding protective cover to the extruder through a second sliding connecting device.

[0004] However, the heat protection cover of the extruder is located around the extrusion barrel. The extrusion barrel will emit a lot of heat during the hot melting of the material. The heat is conducted to the heat protection cover through the air inside the heat protection cover. Therefore, the temperature of the outer periphery of the heat protection cover will continue to rise. If the operator touches the heat protection cover at this time, there is still a risk of burns.

[0005] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide an extruder protection device with high heat dissipation efficiency and effective prevention of contact burns, so as to solve the above-mentioned problems existing in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: an extruder protection device, including a protective cover, characterized in that: the protective cover has connection ports at both ends, an air inlet is provided on the protective cover, a blowing assembly is provided at the air inlet, and an exhaust port is provided on the side of the protective cover opposite to the air inlet. The blowing assembly is used to blow air into the protective cover through the air inlet, and the exhaust port is used to discharge the hot air inside the protective cover.

[0008] By adopting the above technical solution: the protective cover is fitted onto the outer periphery of the extrusion cylinder of the extrusion mechanism through the connection port. When the extrusion structure is heated and extruded, the blowing component can draw in a large amount of air and blow it into the protective cover from the air inlet. The air blows on the outer surface of the extrusion cylinder to dissipate heat. The air blown in cools the extrusion cylinder and blows on the inner wall of the protective cover at the same time, realizing the synchronous heat dissipation of the protective cover and the extrusion cylinder. Then the hot air is discharged from the protective cover through the exhaust port, which improves the heat dissipation capacity of the extrusion cylinder. At the same time, the blowing component can also reduce the temperature of the protective cover and prevent contact burns.

[0009] The extruder protection device described above can be further configured as follows: the exhaust port includes several sets of heat dissipation holes spaced apart on the outer periphery of the protective cover and several sets of heat dissipation grooves spaced apart on the outer periphery of the protective cover, with each pair of adjacent heat dissipation holes being staggered and each pair of adjacent heat dissipation grooves being staggered.

[0010] By adopting the above technical solution, where heat dissipation holes and heat dissipation grooves are distributed alternately, the airflow velocity of hot air when it is blown out of the exhaust port inside the protective cover can be increased, thereby improving the heat dissipation efficiency of the protective cover and effectively reducing the temperature of the protective cover.

[0011] The above-mentioned extruder protection device can be further configured as follows: the protective cover is provided with a protective cover at the exhaust port, the protective cover includes a protective base plate and at least two sets of protective side plates, one end of the protective side plate is connected to the protective base plate, and the other end extends parallel to the side wall of the protective cover with an installation plate, the protective base plate and the protective side plate cooperate to form a heat dissipation channel.

[0012] By adopting the above technical solution: the protective base plate is located above the exhaust vent, which can block the exhaust vent and prevent external dust or impurities from falling into the protective cover from the heat dissipation holes or heat dissipation grooves or blocking the exhaust vent, thus affecting the heat dissipation efficiency of the protective cover. At the same time, the protective cover is fixedly connected to the outer circumference of the protective cover through the mounting plate, and the heat dissipation channel formed by the protective base plate and the protective side plate can guide the blown hot air. In addition, when it is necessary to remove the protective cover, the heat dissipation channel provides a pick-up point, which facilitates the installation and disassembly of the protective cover and improves the convenience of installation and maintenance of the protective device.

[0013] The above-mentioned extruder protective device can be further configured as follows: the protective cover is divided into an upper shell and a lower shell, the air inlet is distributed on the lower shell, the air outlet is distributed on the upper shell, the upper shell is provided with several connecting bolts on the side near the lower shell, the lower shell is provided with connecting holes corresponding to the connecting bolts, the outer peripheral surface of the upper shell is also provided with connecting buckles, and the outer peripheral surface of the lower shell is provided with connecting grooves that cooperate with the connecting buckles.

[0014] By adopting the above technical solution: the connecting bolt and the connecting hole cooperate to achieve the initial positioning and connection of the upper and lower shells. At the same time, the cooperation of the connecting buckle and the connecting slot can quickly and reliably complete the connection and fixation of the upper and lower shells, ensuring the integrity and structural strength of the protective cover. During disassembly, the upper and lower shells can be separated by disengaging the connecting buckle from the connecting slot, which facilitates the assembly of each component with the protective cover. In addition, the protective cover is divided into two parts, which also facilitates the protective cover to be fitted on the outer periphery of the extrusion cylinder and facilitates the disassembly and replacement of the protective cover, thus improving the practicality and convenience of the protective device.

[0015] The aforementioned extruder protection device can be further configured as follows: the blowing assembly includes a suction fan, the air outlet of the suction fan is provided with an air outlet duct, the air outlet duct is provided with a connecting pipe, the end of the connecting pipe is provided with a connecting flange, the air outlet duct is detachably connected to the protective cover through the connecting flange, and an air outlet groove is provided on the outer periphery of the connecting pipe.

[0016] By adopting the above technical solution: the blower draws in air from the bottom of the protective cover and blows the air into the air outlet. The air outlet is volute-shaped, which can guide the airflow and make the air flow more stable. At the same time, the air outlet guides the air from the air inlet into the protective cover through the connecting pipe. The air outlet slots opened on the outer periphery of the connecting pipe can blow the high-speed airflow evenly and dispersedly into the interior of the protective cover along the circumference of the connecting pipe, forming a uniform air curtain around the extrusion cylinder, improving heat dissipation efficiency and avoiding local overheating. At the same time, the air outlet slots are set on the side of the connecting pipe, and the air velocity inside the connecting pipe and the outer periphery of the connecting pipe create an air pressure difference. The air outlet slots can blow in more air and improve heat dissipation efficiency. In addition, the detachable connection between the connecting flange and the protective cover improves the convenience of installation and maintenance of the blower assembly.

[0017] The above-mentioned extruder protection device can be further configured as follows: the outer peripheral surface of the suction fan is provided with two sets of connecting parts, the connecting parts include a fixed plate and a connecting plate, one end of the fixed plate is fixedly connected to the outside of the suction fan and the other end is fixedly connected to the connecting plate, the connecting plate and the fixed plate are obliquely arranged, and the connecting plate is provided with several connecting holes.

[0018] By adopting the above technical solution, the suction fan can be installed in a designated position through two sets of connecting parts, which improves the stability of the blowing component during operation, reduces the risk of structural loosening or detachment caused by vibration, and the fixing plate of the connecting part is fixedly connected to the outer peripheral surface of the suction fan and is set at an angle to the outer peripheral surface of the suction fan. The connecting plate and the fixing plate are also set at an angle, which can further improve the stability of the suction fan during operation. In addition, the connecting holes on the connecting plate can quickly install and fix the connecting plate, which improves the adaptability and convenience of the suction fan installation.

[0019] The extruder protection device described above can be further configured as follows: a water-cooling component is also provided inside the protective cover. The water-cooling component includes a cooling water tank, cooling pipes, and a water pump. Cooling ports for the cooling pipes to enter and exit are provided at both ends of the protective cover. One end of the cooling pipe is connected to the water pump and the other end is connected to the water tank. The cooling pipes are spirally distributed inside the protective cover.

[0020] By adopting the above technical solution: the water pump drives the cooling water to flow out of the cooling water tank, enter the cooling pipe through the inlet, and when the cooling water flows through the cooling pipe into the protective cover, the cooling water flows in a spiral, which can absorb the heat of the protective cover and the heat of the air between the extrusion barrel and the protective cover. Then the cooling water flows back to the water tank through the cooling pipe outlet to achieve cooling circulation. In addition, the water cooling component can work together with the blower component to achieve dual cooling and heat dissipation, which significantly enhances the overall cooling capacity of the extrusion barrel and the protective cover. It is suitable for long-term high-temperature operation conditions, effectively prevents the protective cover and extruder from overheating, and avoids contact burns.

[0021] The aforementioned extruder protection device can be further configured as follows: a filling pipe is connected to the side of the cooling water tank, the end of the filling pipe is provided with a filling interface, a liquid outlet pipe is provided at the bottom of the cooling water tank, the end of the liquid outlet pipe is provided with a liquid outlet interface, and a thermometer for detecting the temperature of the cold zone water is also provided on the side of the cooling water tank.

[0022] By adopting the above technical solution: when the cooling water volume in the cooling water tank is insufficient, the filling port at the end of the filling pipe replenishes the cooling water, preventing insufficient cooling water from reducing heat dissipation efficiency. The outlet pipe is located at the bottom of the tank, facilitating the rapid discharge of old liquid from the outlet port when cooling water needs to be replaced or the tank cleaned, thus simplifying cooling water replacement. Furthermore, by installing a thermometer on the tank, the water temperature inside can be monitored. If the cooling water overheats due to prolonged circulation, cooler cooling water is added through the filling port and hotter cooling water is discharged through the outlet port, thereby reducing the overall temperature of the cooling water within the water-cooled components and maintaining their cooling capacity.

[0023] The beneficial effects of this utility model are as follows: the protective cover is fitted around the outer periphery of the extrusion cylinder, and the cooling air is introduced into the shell from the air inlet through the air blowing component, forming a dual air blowing heat dissipation for the outer surface of the extrusion cylinder and the internal space of the protective cover. The hot air is then quickly discharged through the heat dissipation holes and heat dissipation grooves distributed in a staggered manner on the protective cover, which improves the overall heat dissipation capacity, reduces the surface temperature of the protective cover to prevent burns, and, combined with the water cooling component, the cooling pipes spirally distributed on the inner wall of the shell work together with the air blowing component to form a dual active heat dissipation system, which significantly enhances the heat dissipation capacity of the extruder protective device and prevents contact burns.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1:

[0027] like Figures 1 to 4The extruder protective device shown includes a protective cover 1. The protective cover 1 has connection ports 11 at both ends, an air inlet 12, and a blower assembly 2 at the air inlet 12. An exhaust port 13 is located on the side of the protective cover 1 opposite to the air inlet 12. The blower assembly 2 blows air into the protective cover 1 through the air inlet 12, and the exhaust port 13 discharges hot air from inside the protective cover 1. The protective cover 1 is fitted onto the outer periphery of the extrusion cylinder of the extrusion mechanism through the connection ports 11. During heating and extrusion, the blower assembly 2 draws in a large amount of air and blows it into the protective cover 1 from the air inlet 12, dissipating heat from the outer surface of the extrusion cylinder. The blown air simultaneously cools the extrusion cylinder and cools the inside of the protective cover 1. Finally, the blown air is discharged from inside the protective cover 1 through the exhaust port 13, improving the heat dissipation capacity of the extrusion cylinder. Simultaneously, the blower assembly 2 also reduces the temperature of the protective cover 1, preventing burns from contact.

[0028] The exhaust vent 13 includes several sets of heat dissipation holes 131 spaced apart on the outer periphery of the protective cover 1 and several sets of heat dissipation grooves 132 spaced apart on the outer periphery of the protective cover 1. Each pair of adjacent sets of heat dissipation holes 131 are staggered, and each pair of adjacent sets of heat dissipation grooves 132 are staggered. The staggered distribution of the heat dissipation holes 131 and heat dissipation grooves 132 increases the airflow velocity when the air inside the protective cover 1 is blown out from the exhaust vent 13, thereby improving the heat dissipation efficiency of the protective cover 1 and effectively reducing the temperature of the protective cover 1.

[0029] like Figure 2 The protective cover 1 is provided with a protective cover 14 at the exhaust port 13. The protective cover 14 includes a protective base plate 141 and at least two sets of protective side plates 142. One end of the protective side plate 142 is connected to the protective base plate 141, and the other end extends parallel to the side wall of the protective cover 1 with a mounting plate 143. The protective base plate 141 and the protective side plates 142 cooperate to form a heat dissipation channel 144. The protective base plate 141 is located above the exhaust port 13 and can block the exhaust port 13 to prevent external dust or impurities from falling into the protective cover 1 from the heat dissipation holes 131 or heat dissipation grooves 132 or blocking the exhaust port 13, thus affecting the heat dissipation efficiency of the protective cover 1. At the same time, the protective cover 14 is fixedly connected to the outer peripheral surface of the protective cover 1 through the mounting plate 143. The heat dissipation channel 144 formed by the protective base plate 141 and the protective side plates 142 can guide the blown hot air. In addition, when it is necessary to remove the protective cover 1, the heat dissipation channel 144 provides a removal point, which facilitates the installation and removal of the protective cover 1 and improves the convenience of installation and maintenance of the protective device.

[0030] like Figure 3The protective cover 1 shown is divided into an upper shell 16 and a lower shell 17. The air inlet 12 is distributed on the lower shell 17, and the air outlet 13 is distributed on the upper shell 16. The upper shell 16 is provided with several connecting bolts 161 on the side near the lower shell 17. The lower shell 17 is provided with connecting holes 171 corresponding to the connecting bolts 161. The outer peripheral surface of the upper shell 16 is also provided with connecting buckles 162, and the outer peripheral surface of the lower shell 17 is provided with connecting grooves 172 that cooperate with the connecting buckles 162. The connecting bolt 161 and the connecting hole 171 cooperate to achieve the initial positioning and connection of the upper housing 16 and the lower housing 17. At the same time, the cooperation of the connecting buckle 162 and the connecting slot 172 can quickly and reliably complete the connection and fixation of the upper housing 16 and the lower housing 17, ensuring the integrity and structural strength of the protective cover 1. During disassembly, the upper housing 16 and the lower housing 17 can be separated by disengaging the connecting buckle 162 from the connecting slot 172, which facilitates the assembly of each component with the protective cover 1. In addition, the protective cover 1 is divided into two parts, which also facilitates the protective cover 1 to be fitted on the outer periphery of the extrusion cylinder and facilitates the disassembly and replacement of the protective cover 1, thus improving the practicality and convenience of the protective device.

[0031] like Figure 4 The blower assembly 2 shown includes a suction fan 21. The suction fan 21 has an air outlet duct 22 at its outlet. The air outlet duct 22 has a connecting pipe 23. The end of the connecting pipe 23 has a connecting flange 24. The air outlet duct 22 is detachably connected to the protective cover 1 through the connecting flange 24. An air outlet groove 25 is opened on the outer periphery of the connecting pipe 23. The suction fan 21 draws in air from the bottom of the protective cover 1 and blows the air into the air outlet duct 22. The air outlet duct 22 is volute-shaped, which can guide the air and make the air flow more stable. At the same time, the air outlet duct 22 guides the air from the air inlet 12 into the protective cover 1 through the connecting pipe 23. The air outlet groove 25 opened on the outer periphery of the connecting pipe 23 can blow the high-speed airflow evenly and dispersedly into the interior of the protective cover 1 along the circumference of the connecting pipe 23, forming a uniform air curtain around the extrusion cylinder, improving heat dissipation efficiency and avoiding local overheating. At the same time, the dispersed design of the air outlet groove 25 helps the airflow enter the protective cover 1 smoothly. In addition, the detachable connection between the connecting flange 24 and the protective cover 1 improves the convenience of installation and maintenance of the blower assembly 2.

[0032] The outer circumferential surface of the suction fan 21 is provided with two sets of connectors 26. The connectors 26 include a fixing plate 261 and a connecting plate 262. One end of the fixing plate 261 is fixedly connected to the outside of the suction fan 21, and the other end is fixedly connected to the connecting plate 262. The connecting plate 262 is obliquely arranged to the fixing plate 261, and several connecting holes 263 are provided through the connecting plate 262. The suction fan 21 can be installed in a designated position through the two sets of connectors 26, which improves the stability of the blowing assembly 2 during operation and reduces the risk of structural loosening or detachment caused by vibration. Furthermore, the fixing plate 261 of the connector 26 is fixedly connected to the outer circumferential surface of the suction fan 21 and is obliquely arranged to the outer circumferential surface of the suction fan 21. The connecting plate 262 is also obliquely arranged to the fixing plate 261, which can further improve the stability of the suction fan 21 during operation. In addition, the connecting holes 263 on the connecting plate 262 can be quickly installed and fixed, which improves the adaptability and convenience of the suction fan 21 installation.

[0033] The working principle of this embodiment is as follows: During installation, the upper housing 16 and the lower housing 17 of the protective cover 1 are placed on both sides of the extrusion cylinder, so that the extrusion cylinder is inserted into the connection port. Then, the end of the connecting bolt 161 is inserted into the connection hole 171 until the connecting buckle 162 is engaged in the connection slot 172. At the same time, the blower 21 and the blower 22 are assembled. The blower 22 is installed at the air inlet 12 of the lower housing 17 through the connecting flange 24, thus completing the installation and fixing of the extruder protective device.

[0034] When the heating extrusion mechanism heats and extrudes the material, the blower 21 draws in air and blows it into the protective cover 1 from the air inlet 12 of the lower housing 17 through the air outlet 22. The air blown into the protective cover 1 is then discharged from the heat dissipation hole 131 and heat dissipation groove 132 on the top of the upper housing 16, blowing air to dissipate heat on the extrusion cylinder and the protective cover 1, maintaining the temperature stability of the protective cover 2 and the extrusion cylinder, and preventing contact burns. Example 2:

[0035] Based on Example 1, such as Figure 5 , Figure 6The protective housing 1 shown also contains a water-cooling assembly 3, which includes a cooling water tank 31, cooling pipes 32, and a water pump 33. Cooling ports 15 are provided at both ends of the protective housing 1 for the cooling pipes 32 to enter and exit. One end of the cooling pipes 32 is connected to the water pump 33, and the other end is connected to the water tank 31. The cooling pipes 32 are spirally distributed within the protective housing 1. The water pump 33 drives cooling water to flow from the cooling water tank 31 and into the cooling pipes 32 through the inlet. The cooling pipes 32 are spirally distributed on the inner wall of the protective housing 1. During the flow of cooling water within the cooling pipes 32, it absorbs heat from the protective housing 1 and the air between the extruder and the protective housing 1. The cooling water then flows back to the cooling water tank 31 through the outlet of the cooling pipes 32, achieving a cooling cycle. Furthermore, the water-cooling assembly 3 can work in conjunction with the blower assembly 2 to achieve dual cooling and heat dissipation, significantly enhancing the cooling capacity of the extruder and the protective housing 1. This is suitable for long-term high-temperature operation, effectively preventing the protective housing 1 from overheating and avoiding burns from contact.

[0036] A filling pipe 34 is connected to the side of the cooling water tank 31, and a filling port 341 is provided at the end of the filling pipe 34. A liquid outlet pipe 35 is provided at the bottom of the cooling water tank 31, and a liquid outlet port 351 is provided at the end of the liquid outlet pipe 35. A thermometer 36 for detecting the cooling water temperature is also provided on the side of the cooling water tank 31. When the cooling water volume in the cooling water tank 31 is insufficient, the filling port 341 at the end of the filling pipe 34 replenishes the cooling water to prevent insufficient cooling water from reducing heat dissipation efficiency. The liquid outlet pipe 35 is located at the bottom of the cooling water tank 31, which facilitates the quick discharge of old liquid from the liquid outlet port 351 when the cooling water needs to be replaced or the cooling water tank 31 needs to be cleaned, thus facilitating the replacement of the cooling water. In addition, by installing a thermometer 36 on the cooling water tank 31, the water temperature in the cooling water tank 31 can be monitored. When the cooling water is overheated due to long-term circulation, cooler cooling water is added through the filling port 341 and hotter cooling water is discharged through the outlet port 351, thereby reducing the overall temperature of the cooling water in the water-cooling component 3 and maintaining the cooling capacity of the water-cooling component 3.

[0037] The working principle of this embodiment is as follows: When the heated extrusion mechanism heats and extrudes the material, the blower 21 draws in air and blows it into the protective cover 1 through the air outlet 22 from the air inlet 12 of the lower housing 17. The air blown into the protective cover 1 is then discharged from the heat dissipation holes 131 and heat dissipation grooves 132 on the top of the upper housing 16, which blows air to dissipate heat on the extrusion cylinder and the protective cover 1. At the same time, the water pump 33 draws cooling water from the cooling water tank 31. The cooling water flows into the protective cover 1 through the cold zone pipe 32. The cooling water absorbs the heat of the protective cover 1 and the heat of the air inside the protective cover 1, and works with the blower assembly 2 to achieve a dual heat dissipation effect, maintain the temperature stability of the protective cover 2 and the extrusion cylinder, and prevent contact burns.

[0038] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
