[0032] To address the problem of high-pressure injection of rubber compounds in existing technologies, this application provides an extruder and a vulcanization system.
[0033] See Figures 1 to 5 The extruder includes an outer sleeve 10, an extrusion device 20, a pressure drive device 30, and a moving drive device 40. At least a portion of the extrusion device 20 is located inside the outer sleeve 10 and is capable of feeding material into the outer sleeve 10. The extrusion device 20 is movably disposed relative to the outer sleeve 10 along a first direction. The output end of the pressure drive device 30 is drivenly connected to the extrusion device 20 and drives the extrusion device 20 to move along the first direction. The outer sleeve 10 is connected to the pressure drive device 30. The moving drive device 40 is drivenly connected to the pressure drive device 30 or the extrusion device 20 and drives the extrusion device 20 and the pressure drive device 30 as a whole to move along the first direction to dock with the vulcanizing machine.
[0034] During the operation of the vulcanizing machine, the moving drive unit 40 drives the extruder to move closer to or in the direction of the vulcanizing machine to feed material into the vulcanizing machine. The pressure drive unit 30 drives the extrusion device 20 to slide inside the outer sleeve 10. Through the extrusion of the extrusion device 20, the rubber material located inside the outer sleeve 10 can be pushed into the vulcanizing machine, increasing the pressure of rubber material injection. By driving the extruder to perform two different movements through the pressure drive unit 30 and the moving drive unit 40, the working requirements of the extruder are met.
[0035] In this application, the extruder also includes a base 50, a pressure drive device 30 including a first frame 31, an outer sleeve 10 connected to the first frame 31, the first frame 31 being movably mounted on the base 50 along a first direction, an extrusion device 20 including a second frame 21, the second frame 21 being driven connected to the output end of the pressure drive device 30, the second frame 21 being movably mounted on the base 50 along the first direction, and a moving drive device 40 being driven connected to either the first frame 31 or the second frame 21.
[0036] Specifically, the pressure drive device 30 drives the first frame 31 and the second frame 21 to move closer to or further away from each other. When the first frame 31 and the second frame 21 move closer to each other, the extrusion device 20 can apply pressure to the outer sleeve 10, thereby increasing the pressure at which the extrusion device 20 adds rubber material into the vulcanizing machine. When the movement drive device 40 drives the extrusion device 20 and the pressure drive device 30 to move together, the outer sleeve 10 can be docked with or moved away from the vulcanizing machine.
[0037] In this application, the extrusion device 20 includes an inner sleeve 22, which is axially movable and passes through the inner side of the outer sleeve 10. The inner sleeve 22 is detachably connected to the second frame 21.
[0038] Specifically, the detachable connection between the inner sleeve 22 and the second frame 21 facilitates the replacement of the inner sleeve 22, thereby making it easy to adapt to outer sleeves 10 of different specifications and increasing the adaptability of the equipment.
[0039] In this application, the extruder also includes a guide rail assembly 60, which is provided between the first frame 31 and the base 50, and / or between the second frame 21 and the base 50.
[0040] Specifically, by setting the guide rail assembly 60, the stability of the first frame 31 and the second frame 21 moving on the base 50 can be increased, thereby increasing the stability of the extruder moving on the base 50 and improving the accuracy of the connection between the outer sleeve 10 and the vulcanizing machine. This facilitates the addition of rubber material from the extruder to the vulcanizing machine.
[0041] In this application, the outer sleeve 10 is located at the central axis of the first frame 31.
[0042] In this application, there are multiple pressurization drive devices 30, and each pressurization drive device 30 is evenly distributed along the circumference of the outer sleeve 10.
[0043] Specifically, by setting multiple pressurizing drive devices 30, the pressurizing pressure can be increased, and the outer sleeve 10 is set at the central axis of the first frame 31. Each pressurizing drive device 30 is evenly distributed along the circumference of the outer sleeve 10, which can balance the component forces of each pressurizing drive device 30, so that the outer sleeve 10 located at the central axis obtains the maximum pressure and has no component forces in other directions.
[0044] In this application, the extrusion device 20 includes an inner sleeve 22 and a feeding device 23. The inner sleeve 22 is axially movable and passes through the inner side of the outer sleeve 10. The feeding device 23 is connected to the inner sleeve 22, and at least a portion of the feeding device 23 is located inside the inner sleeve 22 to convey the rubber material from the inner sleeve 22 to the outer sleeve 10.
[0045] In this application, the feeding device 23 includes a feeding drive and a screw. The screw is driven to the feeding drive and is located inside the inner sleeve 22. The feeding drive drives the screw to rotate to feed material to the vulcanizing machine. The extruder also includes a storage cylinder, which is connected to the outer sleeve 10 or the inner sleeve 22 and supplies material to the outer sleeve 10 or the inner sleeve 22.
[0046] Specifically, the feeding device 23 serves to deliver the rubber compound located in the inner sleeve 22 to the outer sleeve 10, and then to the vulcanizing machine. Preferably, the feeding device 23 consists of a screw and a motor that drives the screw to rotate, thereby achieving the transport of the rubber compound through the rotation of the screw.
[0047] In this application, the extruder also includes a positioning device, which is disposed between the vulcanizing machine and the extruder. When the extrusion outlet is aligned with the rubber inlet, the components of the positioning device are aligned to lock the relative position between the vulcanizing machine and the extruder.
[0048] Specifically, the positioning device can increase the stability of the connection between the vulcanizing machine and the extruder, thereby facilitating the transportation of rubber compound. At the same time, the positioning device can fix the vulcanizing machine and the extruder after they are aligned, improving the stability of the extruder during the process of adding rubber compound to the vulcanizing machine.
[0049] In an optional embodiment, the pressurizing drive device 30 has a pressurizing drive piston rod 85, and the second frame 21 is drivenly connected to the pressurizing drive piston rod 85. The end of the pressurizing drive piston rod 85 is fixed to the second frame 21 by a fixing flange 86 and a pressure plate 87. The moving drive device 40 is connected to the inner sleeve 22 by a connector 88.
[0050] In one embodiment, the first direction is angled to the second direction, the outer sleeve has a curved structure and has a first end for connection to a vulcanizing machine and a second end for connection to an extrusion device; the axis of the first end extends along the second direction, and the axis of the second end extends along the first direction.
[0051] In such Figure 2 In one embodiment shown, the axis of the outer sleeve and the axis of the feeding device are not parallel, but at an angle; more precisely, this embodiment employs a configuration where their axes are perpendicular to each other. Specifically, in this embodiment, the outer sleeve and... Figure 1The illustrated embodiment is similar, still employing a straight sleeve design. A connecting port is provided on the outer sleeve, located on its circumferential side, ensuring the axis of the connecting port is perpendicular to the axis of the outer sleeve. Simultaneously, a connecting part is provided on the feeding device, which engages with the outer sleeve through the connecting port, thus achieving cooperation between the feeding device and the outer sleeve. Because the connecting port is on the circumferential side of the outer sleeve, the feeding device is also located on the circumferential side of the outer sleeve, ensuring its axis is perpendicular to the axis of the outer sleeve. This results in the outer sleeve's axis being parallel to the movement trajectory of the extrusion section between the docking and avoidance positions, while the feeding device's axis is perpendicular to the outer sleeve's axis. In this way, the outer sleeve is arranged laterally, while the inner sleeve and feeding device can be arranged longitudinally, reducing the lateral space occupied and achieving a miniaturized layout.
[0052] In one embodiment, the first direction is angled to the second direction, the outer sleeve has a curved structure and has a first end for connection to a vulcanizing machine and a second end for connection to an extrusion device; the axis of the first end extends along the second direction, and the axis of the second end extends along the first direction.
[0053] In such Figure 3 In one embodiment shown, the inner sleeve and the feeding device are arranged longitudinally. However, the outer sleeve in this embodiment is not straight but curved. This means the outer sleeve has two ends facing different directions: a first end for connecting to the vulcanizing machine and a second end for connecting to the feeding device. The axis of the second end is angled to the axis of the first end. The axis of the first end is parallel to the movement trajectory line of the extrusion section between the docking position and the avoidance position; that is, the segment containing the first end extends laterally, so that the opening of the first end faces the vulcanizing machine, enabling feeding cooperation with the vulcanizing machine. The axis of the second end extends longitudinally, allowing the feeding device to be arranged longitudinally. The opening of the second end faces downwards, achieving a cooperative relationship with the inner sleeve and the feeding device.
[0054] In such Figure 4 In one embodiment shown, the outer sleeve includes an interconnected discharge section and an intermediate section. The intermediate section is connected to the extrusion device. There are multiple discharge sections, each of which is connected to the intermediate section. Each discharge section has an independent discharge port.
[0055] like Figure 1 The outer sleeve in the illustrated embodiment has only one extrusion outlet, while Figure 4The outer sleeve of the illustrated embodiment is provided with multiple extrusion outlets. Specifically, the outer sleeve of this embodiment includes an interconnected discharge section and an intermediate section. The intermediate section is connected to the feeding device, while the discharge sections can be coupled to the vulcanizing machine. This embodiment has multiple discharge sections, while there may be only one intermediate section. Each discharge section is connected to the same intermediate section, and each discharge section has an independent extrusion outlet. Correspondingly, the vulcanizing machine also has multiple rubber material inlets, which correspond one-to-one with the extrusion outlets. In this way, the rubber material extruded from the intermediate section can enter each discharge section separately, and then enter the vulcanizing machine through the extrusion outlets on each discharge section, realizing the dispersed extrusion of the rubber material.
[0056] In such Figure 5 In one embodiment shown, there are multiple outer sleeves, and the extrusion device has multiple connecting parts, which are connected and fitted to the outer sleeves one by one. The axis of the outer sleeve is parallel to the axis of the extrusion device.
[0057] The number of outer sleeves can be set as needed, either one or more. When multiple outer sleeves are set, each outer sleeve can be matched with an inner sleeve and a feeding device at the same time, so that the vulcanizing machine can be fed at the same time through multiple outer sleeves.
[0058] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0059] 1. During the operation of the vulcanizing machine, the moving drive device 40 drives the extruder to move closer to or in the direction of the vulcanizing machine to feed material into the vulcanizing machine. The pressure drive device 30 drives the extrusion device 20 to slide inside the outer sleeve 10. Through the extrusion of the extrusion device 20, the rubber material located inside the outer sleeve 10 can be pushed into the vulcanizing machine, increasing the pressure of rubber material injection. By driving the extruder to perform two different movements through the pressure drive device 30 and the moving drive device 40, the working requirements of the extruder are met.
[0060] 2. The pressure drive device 30 drives the first frame 31 and the second frame 21 to move closer to or further away from each other. When the first frame 31 and the second frame 21 move closer to each other, the extrusion device 20 can apply pressure to the outer sleeve 10, thereby increasing the pressure of the extrusion device 20 adding rubber material into the vulcanizing machine. When the movement drive device 40 drives the extrusion device 20 and the pressure drive device 30 to move as a whole, the outer sleeve 10 can be docked with or moved away from the vulcanizing machine.
