[0027] To address the problem that extruders in the prior art struggle to achieve the required high pressure, this application provides an extruder and a vulcanization system.

[0028] See Figure 1The extruder includes an outer sleeve 10, an inner sleeve 20, a feeding device 30, and a pressurizing device 40. The inner sleeve 20 is axially movable and passes through the inner sleeve 20. The interior of the outer sleeve 10 and the inner sleeve 20 serves as an extrusion chamber. The feeding device 30 is connected to the inner sleeve 20 and moves synchronously with the inner sleeve 20. At least a portion of the feeding device 30 extends into the inner sleeve 20 and feeds rubber material into the inner sleeve 20. The end of the outer sleeve 10 away from the feeding device 30 has an extrusion outlet for cooperating with a vulcanizing machine. The output end of the pressurizing device 40 is drivenly connected to the inner sleeve 20 or the feeding device 30 and drives the feeding device 30 and the inner sleeve 20 to pressurize and move closer to the vulcanizing machine.

[0029] In actual use, the rubber compound is first added to the inner sleeve 20, then through the inner sleeve 20 into the outer sleeve 10, and finally through the outer sleeve 10 into the vulcanizing machine. During the rubber compound addition process, a portion of the pressure is first provided by the feeding device 30, and then another portion of the pressure is provided by the pressurizing device 40. By providing pressure to the rubber compound added into the vulcanizing machine through both the feeding device 30 and the pressurizing device 40, high-pressure injection of the rubber compound is achieved.

[0030] In this application, the feeding device 30 includes a feeding drive and a screw. The screw is driven to the feeding drive and is located inside the inner sleeve 20. The feeding drive drives the screw to rotate to feed material into the vulcanizing machine. The extruder also includes a storage cylinder, which is connected to the extrusion chamber and supplies material into the extrusion chamber.

[0031] Specifically, the rotation of the screw facilitates the transfer of rubber material from the inner sleeve 20 to the outer sleeve 10, while the storage cylinder facilitates the addition of rubber material into the inner sleeve 20, thus making it easier to add the rubber material into the vulcanizing machine.

[0032] In this application, the extruder also includes a base 50, a first frame 51 and a second frame 52, an outer sleeve 10 and a pressurizing device 40 connected to the first frame 51, and the first frame 51 is movably mounted on the base 50 along the axial direction of the outer sleeve 10; the second frame 52, the output end of the pressurizing device 40 is drivenly connected to the second frame 52, the inner sleeve 20 and the feeding device 30 are connected to the second frame 52, and the second frame 52 is movably mounted on the base 50 along the axial direction of the outer sleeve 10.

[0033] Specifically, the pressurizing drive device drives the first frame 51 and the second frame 52 to move closer to or further away from each other. When the first frame 51 and the second frame 52 move closer to each other, the inner sleeve 20 can pressurize the outer sleeve 10, thereby increasing the pressure of the extruder adding rubber material into the vulcanizer.

[0034] In this application, the extruder also includes a connecting assembly 60. The cylinder of the connecting assembly 60 and the pressurizing device 40 are respectively located on opposite sides of the second frame 52. The connecting assembly 60 is connected to the cylinder rod of the second frame 52 and the pressurizing device 40, so that the pressurizing device drives the second frame 52 to move through the connecting assembly 60.

[0035] Specifically, the output end of the pressurizing device 40 is connected to the second frame 52 via the connecting component 60. When the pressurizing device 40 is working, the connecting component 60 facilitates the movement of the second frame 52.

[0036] In this application, the extruder also includes a transition piece 70, through which the inner sleeve 20 is detachably connected to the second frame 52.

[0037] Specifically, the detachable connection between the inner sleeve 20 and the second frame 52 facilitates the replacement of the inner sleeve 20, thereby making it easier to adapt to different specifications of outer sleeves 10 and increasing the adaptability of the equipment.

[0038] 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.

[0039] 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 connection between the rubber compound and the extruder during the process of adding the rubber compound to the vulcanizing machine.

[0040] In this application, the extruder also includes a plunger head 90, which is connected to the inner sleeve 20 and slidably connected to the outer sleeve 10.

[0041] In this application, the extruder also includes a one-way valve 91, which is disposed on the plunger head 90.

[0042] By installing a plunger head 90 on the inner sleeve 20 and a one-way valve 91 on the plunger head 90, the stability of rubber material transportation can be increased, and the rubber material in the sleeve can be prevented from entering the inner sleeve 20 due to increased pressure, thereby ensuring the stability of the rubber material added to the vulcanizing machine.

[0043] In one embodiment, the first direction is angled to the second direction, the outer sleeve 10 has a curved structure and has a first end for connection to a vulcanizing machine and a second end for connection to a feeding device 30; the axis of the first end extends along the second direction, and the axis of the second end extends along the first direction.

[0044] In this embodiment, the axis of the outer sleeve 10 is not parallel to the axis of the feeding device 30, but rather at an angle. More precisely, this embodiment uses a configuration where the axes of the two are perpendicular to each other. Specifically, the outer sleeve 10 in this embodiment still adopts the form of a straight sleeve. Please refer to [link to previous text]. Figure 1 A connecting port is provided on the outer sleeve 10, and the connecting port is located on the circumferential side of the outer sleeve 10, so that the axis of the connecting port is perpendicular to the axis of the outer sleeve 10. Simultaneously, a connecting part is provided on the feeding device 30, which engages with the outer sleeve 10 through the connecting port, thereby achieving the engagement between the feeding device 30 and the outer sleeve 10. Since the connecting port is on the circumferential side of the outer sleeve 10, the feeding device 30 is also located on the circumferential side of the outer sleeve 10, thus the axis of the feeding device 30 is perpendicular to the axis of the outer sleeve 10. This results in the axis of the outer sleeve 10 being parallel to the movement trajectory line of the extrusion section between the docking position and the avoidance position, while the axis of the feeding device 30 is perpendicular to the axis of the outer sleeve 10. In this way, the outer sleeve 10 is arranged laterally, while the inner sleeve 20 and the feeding device 30 can be arranged longitudinally, thereby reducing the lateral space occupied and achieving a miniaturized layout.

[0045] In one embodiment, the first direction is angled to the second direction, the outer sleeve 10 has a curved structure and has a first end for connection to a vulcanizing machine and a second end for connection to a feeding device 30; the axis of the first end extends along the second direction, and the axis of the second end extends along the first direction.

[0046] In this embodiment, the inner sleeve 20 and the feeding device 30 are arranged longitudinally. However, the outer sleeve 10 is not straight but curved. This means the outer sleeve 10 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 30. 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 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 30 to be arranged longitudinally. The opening of the second end faces downwards, enabling cooperation with the inner sleeve 20 and the feeding device 30.

[0047] In one embodiment, the outer sleeve 10 includes an interconnected discharge section and an intermediate section. The intermediate section is connected to the feeding device 30. There are multiple discharge sections, and each discharge section is connected to the intermediate section. Each discharge section has an independent discharge port.

[0048] exist Figure 1 The outer sleeve 10 in the illustrated embodiment has only one extrusion outlet, while the outer sleeve 10 in this embodiment has multiple extrusion outlets (not shown in the figure). Specifically, the outer sleeve 10 in this embodiment includes an interconnected discharge section and an intermediate section. The intermediate section is connected to the feeding device 30, while the discharge section can be connected 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.

[0049] In one embodiment, there are multiple outer sleeves 10, and the feeding device 30 has multiple connecting parts, which are connected and engaged with the outer sleeves 10 in a one-to-one correspondence. The axis of the outer sleeve 10 is parallel to the axis of the feeding device 30.

[0050] The number of outer sleeves 10 can be set as needed, either one or more. When there are multiple outer sleeves 10, each outer sleeve 10 can be simultaneously matched with an inner sleeve 20 and a feeding device 30, so that multiple outer sleeves 10 can be used to feed material into the vulcanizing machine at the same time.

[0051] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0052] 1. In actual use, the rubber compound is first added to the inner sleeve 20, then through the inner sleeve 20 to the outer sleeve 10, and finally through the outer sleeve 10 into the vulcanizing machine. During the rubber compound addition process, a portion of the pressure is first provided by the feeding device 30, and then another portion of the pressure is provided by the pressurizing device 40. The pressure provided to the rubber compound in the vulcanizing machine by both the feeding device 30 and the pressurizing device 40 achieves high-pressure injection of the rubber compound.

[0053] 2. The pressure drive device drives the first frame 51 and the second frame 52 to move closer to each other or further away from each other. When the first frame 51 and the second frame 52 move closer to each other, the inner sleeve 20 can pressurize the outer sleeve 10, thereby increasing the pressure of the extruder adding rubber material into the vulcanizer.

[0054] 3. By setting a plunger head 90 on the inner sleeve 20 and a one-way valve 91 on the plunger head 90, the stability of rubber material transportation can be increased, and the rubber material in the sleeve can be prevented from entering the inner sleeve 20 due to increased pressure, thereby ensuring the stability of the rubber material added to the vulcanizing machine.
