Description

Technical Field

[0001] The utility model relates to the technical field of extruders, and more specifically, to a cable production extruder provided with an exhaust structure. Background Art

[0002] A cable extruder is a key device for manufacturing cables. It heats and melts insulating materials such as plastic or rubber. Through the rotation and extrusion of the screw, the material is evenly extruded and wrapped around the periphery of the conductor to form an insulating protective layer. Traditional cable extruders consist of a feed port and an extruder body. Production can begin simply by placing the material into the feed port. However, during the feeding process, the material is mixed with air, causing bubbles to be trapped in the cable during production, affecting the quality of the cable. In order to address the shortcomings of the existing technology, we have proposed a cable extruder with an exhaust structure. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a cable production extruder with an exhaust structure to solve the problem that during the feeding process, the material is mixed with air, causing bubbles to be mixed in the cable during the production process, thereby affecting the quality of the cable.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a cable production extruder provided with an exhaust structure, comprising an extruder body, an extruder feed port provided at the top of the extruder body, an exhaust assembly provided at the top of the extruder feed port, and a dredging assembly provided inside the exhaust assembly;

[0005] The top of described outer cylinder is fixed with the top of outer cylinder of described outer cylinder, and the bottom of described outer cylinder is fixedly connected with the piston rod of described outer cylinder.

[0006] The inner cavity of the material barrel is used to put the material to be processed, and the protective pad is used to protect the bottom surface of the piston.

[0007] Among them, the top surface of the sealing baffle 1 is in contact with the bottom surface of the funnel mouth, and the sealing baffle 1 is used to seal the bottom outlet of the funnel mouth. The bottom surface of the sealing baffle 2 is in contact with the exhaust pipe, and the sealing baffle 2 is used to seal the outlet of the exhaust pipe.

[0008] Among them, the dredging component includes a bracket 2, which is fixedly installed on the inner wall of the material barrel. A motor and a protective cover are fixedly installed on the top of the bracket 2, and the protective cover is located above the motor. One end of the motor's rotating shaft is fixedly connected to a stirring frame, and the top surface of the sealing baffle 1 is fixedly connected to a push rod. The inner cavity of the transfer box is provided with an inclined rail.

[0009] The ejector rod is located at the center of the funnel mouth, and the inclined rail is used to guide the material into the extruder feed port.

[0010] The protective cover is used to protect the motor, and the stirring frame is composed of a plurality of cylindrical rods and brackets connecting them, and the plurality of cylindrical rods are perpendicular to the central axis of the material barrel.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model uses an exhaust component, including a material barrel, to put the material into the inner cavity of the material barrel, then start the cylinder to extend the push rod, so that the piston squeezes the air in the inner cavity of the material barrel, and the pressurized air pushes the sealing baffle two open and flows out. At this time, most of the air in the material barrel and the inner cavity of the funnel mouth is discharged, and the cylinder one contracts the push rod to drive the piston to rise. At this time, the air density of the material barrel and the inner cavity of the funnel mouth is greatly reduced, and at the same time, the sealing baffle two is tightly pressed against the outlet of the exhaust pipe by the atmospheric pressure, so that the cylinder two extends the push rod to drive the sealing baffle one to rotate, and open the bottom outlet of the funnel mouth. The material enters the inner cavity of the transfer box under the action of gravity. By utilizing the above structure, the air in the inner cavity of the material barrel is squeezed out by the piston, so that the air mixed in the feeding process is reduced, the bubbles generated during the production of the cable can be reduced, the quality of the cable is improved, and the flexibility of the device is improved.

[0013] The utility model uses a dredging component, including a stirring frame and a push rod. When the material gradually flows out of the funnel mouth, the motor is started to drive the stirring frame to stir the material in the inner cavity of the material barrel to prevent the material from being blocked. If the material is blocked at the bottom outlet of the material barrel, the second cylinder drives the sealing baffle to rotate, so that the push rod pushes the blocked material out of a gap, allowing the material to continue to flow out. Finally, under the guidance of the inclined rail, the material gradually flows into the feed port of the extruder. With the above structure, the material in the material barrel is stirred by the stirring frame, and the push rod pushes the blocked material out of the gap, which can avoid the material from being blocked in the material barrel and the funnel mouth, improves the fluidity of the extruder during feeding, and enhances the practicality of the device.

[0020] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0021] As attached Figure 1 To the attached Figure 4 The embodiment of the present utility model provides a cable production extruder with an exhaust structure, comprising an extruder body 1, an extruder feed port 2 is provided on the top of the extruder body 1, an exhaust component 3 is provided on the top of the extruder feed port 2, and a dredging component 4 is provided inside the exhaust component 3;

[0022] The exhaust assembly 3 includes a transfer box 31, which is fixedly mounted on the top of the extruder feed port 2. A bracket 32 ​​is fixedly mounted on the top of the transfer box 31, and a cylinder 33 is fixedly mounted on the bottom of the bracket 32. One end of the push rod of the cylinder 33 is fixedly connected to a piston 34, and the bottom surface of the piston 34 is fixedly connected to a pad 35. A material barrel 361 is fixedly mounted on the top of the transfer box 31, and the piston 34 is slidably connected to the inner wall of the material barrel 361. A funnel 362 is fixedly mounted on the bottom of the material barrel 361, and the inner wall of the transfer box 31 is rotatably connected to a seal. Baffle 1 37, a sliding groove 38 is provided on the bottom surface of the sealing baffle 1 37, and the sealing baffle 1 37 is slidably connected to the slider 39 through the sliding groove 38. The bottom surface of the inner cavity of the transfer box 31 is fixedly installed with a cylinder 2 311, and the push rod of the cylinder 2 311 is rotatably connected to the slider 39. The outer surface of one side of the material barrel 361 is fixedly connected to the exhaust pipe 312, and a filter screen 313 is provided on one side of the exhaust pipe 312. A plurality of limiting rods 314 are fixedly connected to the top of the exhaust pipe 312, and the exhaust pipe 312 is slidably connected to the sealing baffle 2 315 through a plurality of limiting rods 314.

[0023] The inner cavity of the material barrel 361 is used to put the material to be processed, and the pad 35 is used to protect the bottom surface of the piston 34;

[0024] By driving the piston 34 to rise through cylinder 1 33, the material to be processed can be placed in the inner cavity of the material barrel 361, and by driving the slider 39 to rise and fall through cylinder 2 311, the sealing baffle 1 37 can be driven to rotate, thereby sealing or opening the outlet of the funnel mouth 362, and the filter screen 313 can prevent the material from entering the exhaust pipe 312.

[0025] The top surface of the sealing baffle 1 37 is in contact with the bottom surface of the funnel opening 362, and the sealing baffle 1 37 is used to seal the bottom outlet of the funnel opening 362. The bottom surface of the sealing baffle 2 315 is in contact with the exhaust pipe 312, and the sealing baffle 2 315 is used to seal the outlet of the exhaust pipe 312.

[0026] By driving the piston 34 downward through the cylinder 1 33, the air in the material barrel 361 can be squeezed, so that the pressurized air will lift the sealing baffle 2 315 and flow out from the exhaust pipe 312. At the same time, the pad 35 can prevent the material from scratching the bottom surface of the piston 34. When the cylinder 1 33 drives the piston 34 upward again, the air pressure in the inner cavity of the material barrel 361 will decrease. At the same time, under the action of atmospheric pressure, the sealing baffle 2 315 will firmly close the outlet of the exhaust pipe 312. Then, the cylinder 2 311 drives the sealing baffle 1 37 to open the outlet of the funnel mouth 362. Under the action of gravity, the material enters the inner cavity of the transfer box 31 from the funnel mouth 362 with extremely low air content.

[0027] Among them, the dredging component 4 includes a bracket 2 41, which is fixedly installed on the inner wall of the material barrel 361. A motor 42 and a protective cover 43 are fixedly installed on the top of the bracket 2 41, and the protective cover 43 is located above the motor 42. One end of the rotating shaft of the motor 42 is fixedly connected to a stirring frame 44, and the top surface of the sealing baffle 1 37 is fixedly connected to a push rod 45. The inner cavity of the transfer box 31 is provided with an inclined rail 46.

[0028] Among them, the ejector rod 45 is located in the center of the funnel opening 362, and the inclined rail 46 is used to guide the material into the extruder feed port 2;

[0029] By driving the sealing baffle 1 37 to rotate with the cylinder 2 311 , the push rod 45 can push the material blocked in the inner cavity of the funnel opening 362 out of the gap, so that the blocked material can flow into the inner cavity of the transfer box 31 and then flow into the extruder feed port 2.

[0030] The protective cover 43 is used to protect the motor 42, and the stirring frame 44 is composed of a plurality of cylindrical rods and brackets connecting them, and the plurality of cylindrical rods are perpendicular to the central axis of the material barrel 361;

[0031] The motor 42 drives the stirring frame 44 to rotate, so as to stir the material in the inner cavity of the material barrel 361 and make the material flow in the inner cavity of the material barrel 361 to prevent the material from being blocked.

[0032] The working process of this utility model is as follows:

[0033] First, put the material into the inner cavity of the material barrel 361, then start the cylinder 1 33 to extend the push rod, so that the piston 34 squeezes the air in the inner cavity of the material barrel 361, and the pressurized air pushes the sealing baffle 2 315 open and flows out. At this time, most of the air in the inner cavity of the material barrel 361 and the funnel mouth 362 is discharged, so that the cylinder 1 33 retracts the push rod to drive the piston 34 to rise. At this time, the air density in the inner cavity of the material barrel 361 and the funnel mouth 362 is greatly reduced, and at the same time, the sealing baffle 2 315 is tightly pressed against the outlet of the exhaust pipe 312 by the atmospheric pressure, so that the cylinder 2 311 extends the push rod, with The dynamic sealing baffle 1 37 rotates to open the bottom outlet of the funnel mouth 362, and the material enters the inner cavity of the transfer box 31 under the action of gravity. When the material gradually flows out of the funnel mouth 362, the motor 42 is started to drive the stirring frame 44 to stir the material in the inner cavity of the material barrel 361 to prevent the material from being blocked. If the material is blocked at the bottom outlet of the material barrel 361, the cylinder 2 311 drives the sealing baffle 1 37 to rotate, so that the push rod 45 pushes the blocked material out to create a gap, allowing the material to continue to flow out. Finally, under the guidance of the inclined rail 46, the material gradually flows into the extruder feed port 2.
