Description

Technical Field

[0001] The utility model relates to the technical field of extruders, and particularly relates to a sealed oil tank structure of an extruder and an extruder. Background Technique

[0002] Traditional copper-aluminum profile extruders all adopt an upper open oil tank. When the plunger cylinder moves forward and backward without load, it is pushed by the auxiliary cylinder, and the hydraulic oil enters and returns through the filling valve. When entering the oil, it is pushed by the gravity effect, so the hydraulic oil is in contact with the atmosphere for a long time. Since the flow rate of the hydraulic oil is very large during each operation, it is easy to mix in air and dust, and there are many oil circuit valves and oil pumps on the oil circuit of the extruder. Therefore, it is also easy to inhale and mix in gas. Therefore, such an open oil tank seriously affects the use effect of the hydraulic oil, reduces the service life of the hydraulic oil, is not conducive to energy conservation and environmental protection, and saving costs. Content of the Utility Model

[0003] The purpose of the utility model is to provide a sealed oil tank structure of an extruder and an extruder to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems:

[0005] The utility model provides a sealed oil tank structure of an extruder, including an oil tank body, a piston assembly and a connecting pipe. The piston assembly includes a piston cylinder and a piston body. The piston body is slidably installed in the piston cylinder. The piston body divides the interior of the piston cylinder into a first piston chamber and a second piston chamber. The second piston chamber communicates with the outside; the connecting pipe is connected between the first piston chamber and the oil tank body.

[0006] The beneficial effect of the utility model is:

[0007] When in use, the sealed oil tank structure of this extruder is connected to the vent hole of the oil tank body through the connecting pipe, that is, the piston cylinder communicates with the air inside the oil tank. When the hydraulic system of the extruder operates, the oil tank experiences two working states of oil inlet and oil return, and the internal pressure of the oil tank changes accordingly. The pressure in the first piston chamber is the same as the internal pressure of the oil tank. Therefore, the piston also moves accordingly, making the internal pressure of the oil tank more balanced. Avoiding external dust from entering the oil circuit of the oil tank, effectively avoiding the hydraulic oil from being easily contaminated, and better ensuring the stable performance of the extruder. Specifically, this sealed structure avoids mixing in dust and other sundries, maintains the cleanliness of the hydraulic oil, delays the working life of the hydraulic oil, and because the hydraulic oil is transported under relatively sealed pressure, the machine works stably. Thus, it solves the problems that the oil circuit of the existing extruder is in contact with the atmosphere, affecting the quality and service life, etc., and effectively improves the use quality of the hydraulic oil of the extruder and extends the service life.

[0008] As a further improvement of the above technical solution, the closed fuel tank structure of the extruder further includes a reset assembly. The reset assembly includes a reset driving member, which is in transmission connection with the piston body. The reset driving member is used to drive the piston body to slide along the piston cylinder so that the piston body is reset. The reset driving member drives the piston body to move back to its original position, and the position of the piston can be immediately known through the movement stroke of the reset member.

[0009] As a further improvement of the above technical solution, the piston cylinder is provided with an end cover. The piston body is connected to at least one guide rod, and the at least one guide rod slides in the end cover. The at least one guide rod is in transmission connection with the reset driving member. The guide rod plays a guiding role and improves the movement accuracy. The reset driving member drives the guide rod to move back and forth, thereby driving the piston cylinder to move back and forth.

[0010] As a further improvement of the above technical solution, the reset assembly further includes a slide rail and a sliding seat. The at least one guide rod is arranged on the sliding seat, and the sliding seat slides on the slide rail, improving the sliding stability.

[0011] As a further improvement of the above technical solution, the piston cylinder extends horizontally. When the piston cylinder extends horizontally, the space can be utilized more effectively, especially in an environment with limited space. This design allows the cylinder assembly to expand in the horizontal direction, avoiding a large occupation of vertical space, thereby improving the space utilization rate of the overall equipment; setting the reset assembly on the side where the piston body is located can make the layout of the entire cylinder assembly more compact and reasonable. This layout not only reduces unnecessary space waste but also helps to improve the overall performance and stability of the equipment; the reset assembly and the piston body are arranged on the same side, enabling maintenance personnel to more conveniently access and inspect these key components. When maintenance or replacement is required, the complexity of disassembly and installation can be reduced, improving the maintenance efficiency.

[0012] As a further improvement of the above technical solution, an air filter is provided at the communication port between the second piston chamber and the outside. The air filter plays a role of secondary filtration, which can prevent dust and impurities from entering through the gap between the piston cylinder and the piston body, and further avoid mixing in sundries such as dust.

[0013] As a further improvement of the above technical solution, a plurality of balls are arranged between the outer peripheral wall of the piston body and the inner side wall of the piston cylinder, improving the smoothness of the piston body sliding, and the piston body changes accordingly according to the air pressure in a timely manner.

[0014] As a further improvement of the above technical solution, the closed fuel tank structure of the extruder further includes a housing, and the piston assembly is arranged in the housing. The housing can further isolate the piston assembly from the outside, preventing sundries such as dust from entering the second chamber through the air filter.

[0015] As a further improvement of the above technical solution, the housing includes a frame and a plurality of transparent partitions, and the plurality of transparent partitions cover the inside of the frame. The frame, as the main support structure of the housing, is made of high-strength materials such as steel or aluminum alloy, and has good load-bearing capacity and stability. It can effectively support the weight of the entire housing and resist various external forces. Although the transparent partitions mainly play a role in covering and isolating, their close combination with the frame also enhances the overall structural strength of the housing.

[0016] The present utility model provides an extruder, including the closed fuel tank structure of the extruder described in any one of the above. The hydraulic system of the extruder avoids mixing in dust and other sundries, maintains the cleanliness of the hydraulic oil, delays the working life of the hydraulic oil, and moreover, due to the use of relatively sealed pressure to transport the hydraulic oil, the machine works stably.

[0027] Referring to Figures 1 to 5 , a closed fuel tank structure of an extruder and an extruder of the present utility model are provided, and the following embodiments are made:

[0028] A closed fuel tank structure of an extruder includes a housing 600, an oil tank body 100, a piston assembly 200 and a connecting pipe 300. The piston assembly 200 includes a piston cylinder 210 and a piston body 220. The piston body 220 is slidably installed in the piston cylinder 210. The piston body 220 divides the interior of the piston cylinder 210 into a first piston chamber 201 and a second piston chamber 202. The second piston chamber 202 communicates with the outside. The connecting pipe 300 is connected between the first piston chamber 201 and the oil tank body 100.

[0029] During use, the closed fuel tank structure of this extruder is connected to the vent hole of the oil tank body 100 through the connecting pipe 300, that is, the piston cylinder 210 communicates with the air inside the fuel tank. When the hydraulic system of the extruder is operating, the fuel tank experiences two working states of oil inlet and oil return, and the internal pressure of the fuel tank changes accordingly. The pressure in the first piston chamber 201 is the same as the internal pressure of the fuel tank. Therefore, the piston also moves correspondingly in position, making the internal pressure of the fuel tank more balanced. It avoids external dust from entering the fuel tank oil circuit, thus effectively preventing the hydraulic oil from being easily contaminated and better ensuring the stable performance of the extruder. Specifically, this sealed structure avoids the mixing of dust and other sundries, maintains the cleanliness of the hydraulic oil, delays the working life of the hydraulic oil, and moreover, due to the use of relatively sealed pressure to transport the hydraulic oil, the machine works stably. Thus, it solves the problems that the existing extruder oil circuit is in contact with the atmosphere, affecting the quality and service life, etc., and effectively improves the use quality of the hydraulic oil of the extruder and extends the service life.

[0030] Specifically, the piston assembly 200 includes a piston cylinder 210 and a piston body 220. The piston cylinder 210 is cylindrical and extends laterally. The piston end is slidably provided with the piston body 220. In order to improve the sliding stability of the piston body 220, a plurality of balls 240 are provided on the side of the piston body 220. The balls 240 are slidably arranged on the inner wall of the piston cylinder 210 to improve the smoothness of the sliding of the piston body 220. The piston body 220 changes in time according to the air pressure.

[0031] The front side of the piston cylinder 210 is provided with an end cover 230, and the end cover 230 is provided with a connecting pipe, and the outlet of the connecting pipe is provided with two air filters 500, and the second piston chamber 202 is connected to the outside through the air filter 500. The air filter 500 plays a secondary filtering role, which can prevent dust and impurities from entering through the gap between the piston cylinder 210 and the piston body 220, and further prevent dust and other sundries from mixing in.

[0032] The extrusion sealing oil tank structure also includes a reset assembly 400, which includes a reset driver 410. The reset driver 410 is transmission-connected to the piston body 220, and the reset driver 410 is used to drive the piston body 220 to slide along the piston cylinder 210 so that the piston body 220 is reset.

[0033] The reset drive member 410 drives the piston body 220 to move and reset to the original position, and the position of the piston is instantly known through the movement stroke of the reset member. At the same time, the position of the piston body 220 can be detected by the detection component, and the detection component specifically includes a detection sensor.

[0034] The reset drive member 410 includes a cylinder assembly. In some other embodiments, the reset drive member 410 can use an electric push rod or a motor screw drive as a drive unit, and is provided with a corresponding slide rail 430 to improve the accuracy of the movement.

[0035] The piston body 220 is connected to one end of three guide rods 420. The guide rods 420 pass through the end cover 230 and are slidably arranged on the end cover 230. A bearing is arranged between the guide rods 420 and the end cover 230 to improve the motion accuracy and reduce friction and wear. The reset assembly 400 also includes two slide rails 430 and a slide seat 440. The other ends of the three guide rods 420 are connected to the slide seat 440. Both ends of the slide seat 440 are slidably arranged on the slide rails 430 to improve the sliding stability. The reset drive 410 is a cylinder. The output end of the cylinder is in transmission connection with the slide seat 440. The cylinder drives the piston body 220 to move by driving the slide seat 440 to move back and forth.

[0036] The rear end of the piston cylinder 210 is hermetically connected to the housing 600, and the connecting pipe 300 communicates with the first cavity of the piston cylinder 210 from the sealed end. The connecting pipe 300 directly communicates with the first cavity of the piston cylinder 210, which simplifies the setting method of the connecting pipe 300 and makes the structure simpler. Otherwise, the connecting pipe 300 needs to pass through the housing 600 and then be connected to the piston cylinder 210. When the connecting pipe 300 passes through the housing 600, requirements such as sealing need to be considered, and the connection is more complex.

[0037] The piston cylinder 210 is arranged to extend horizontally, and the reset assembly 400 is arranged on the front side of the piston cylinder 210. When the piston cylinder 210 extends horizontally, the space can be utilized more effectively, especially in an environment with limited space. This design allows the cylinder assembly to expand in the horizontal direction, avoiding a large occupation of the vertical space, thereby improving the space utilization rate of the overall equipment; arranging the reset assembly 400 on the side where the piston body 220 is provided can make the layout of the entire cylinder assembly more compact and reasonable. This layout not only reduces unnecessary space waste but also helps to improve the overall performance and stability of the equipment; the reset assembly 400 is arranged on the same side as the piston body 220, enabling maintenance personnel to more conveniently access and inspect these key components. When maintenance or replacement is required, the complexity of disassembly and installation can be reduced, and the maintenance efficiency can be improved.

[0038] The cylindrical shape has a smaller surface area under the same volume, which means less material is required during the manufacturing process. This not only reduces the manufacturing cost but also reduces material waste; the cylindrical shape has good structural stability and can withstand a large internal pressure without deformation or rupture; the cylindrical shape enables the piston and the sealing mechanism inside the piston cylinder 210 to be more easily designed and installed. When the piston body 220 moves inside the piston cylinder 210, the sealing surface between its periphery and the tank wall can remain relatively constant, thereby improving the sealing performance; the cylindrical shape also facilitates the injection of sealing materials such as grease into the sealing mechanism to further improve the sealing effect and reduce friction. The piston cylinder 210 can be made of a transparent material for easy observation or can also be welded from steel plates.

[0039] The entire piston assembly 200 is arranged inside the housing 600. The housing 600 can further isolate the piston assembly 200 from the outside world, preventing dust and other sundries from entering the second cavity through the air filter 500. It can further prevent dust from entering the inside of the fuel tank.

[0040] The housing 600 includes a frame 610 and a plurality of transparent partitions 620. The frame 610 is in the shape of a cuboid, and the plurality of transparent partitions 620 cover the inside of the frame 610. The frame 610, as the main support structure of the housing 600, is made of high-strength materials such as steel or aluminum alloy, and has good load-bearing capacity and stability. It can effectively support the weight of the entire housing 600 and resist various external forces. Although the transparent partitions 620 mainly play a role of covering and isolating, their close combination with the frame 610 also enhances the overall structural strength of the housing 600.

[0041] The present utility model provides an embodiment of an extruder, including the closed fuel tank structure of an extruder as described in any one of the above. The hydraulic system of the extruder avoids mixing in dust and other sundries, maintains the cleanliness of the hydraulic oil, delays the working life of the hydraulic oil, and moreover, due to the use of relatively sealed pressure to transport the hydraulic oil, the machine works stably.

[0042] The above has specifically described the preferred embodiments of the present utility model, but the present invention is not limited to the embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
