The current method involves replacing the entire extrusion cylinder, a complex process that also presents challenges due to intermittent heating intervals.

[0003] To reduce workload and improve efficiency, technicians have opted to replace the liner of the extrusion cylinder. However, replacing the liner requires manual labor in conjunction with a crane, which is inefficient. Utility Model Content

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail.

[0028] This application discloses a quick-change device for extrusion dies.

[0029] Reference Figure 1 and Figure 2 A quick-change extrusion die device includes an extruder 1, a transport mechanism 2 for transporting an inner liner is provided on one side of the extruder 1, the transport mechanism 2 is connected to a positioning mechanism, and pushing mechanisms 4 for pushing the inner liner are provided on both sides of the extruder 1. This solution achieves quick replacement of the inner liner through automated transport and positioning mechanisms, significantly improving production efficiency and reducing downtime.

[0030] Reference Figure 1 and Figure 2 The transport mechanism 2 includes a conveyor belt 21 horizontally arranged on the side of the extruder 1, and the positioning mechanism includes a positioning frame 3 arranged on the end of the conveyor belt 21 near the extrusion cylinder. The positioning frame 3 includes a base 31, a lifting hydraulic cylinder 32 is arranged on the base 31, a positioning frame 33 is arranged on the lifting hydraulic cylinder 32, and a positioning groove 34 is arranged on the positioning frame 33.

[0031] Reference Figure 1 and Figure 2The positioning groove 34 matches the shape of the inner lining to ensure that the inner lining can enter the positioning groove 34 accurately; the base 31 is also provided with casters 35, which can facilitate the movement of the positioning frame 3 and make it flexible to adjust its position to adapt to different production environments; the casters 35 should have a locking function to prevent accidental movement during operation.

[0032] Reference Figure 1 and Figure 2 The pushing mechanism 4 includes a pushing hydraulic cylinder 41 located on the side of the positioning mechanism away from the extrusion mechanism. The piston rod of the pushing hydraulic cylinder 41 forms an abutting fit with the inner liner. The pushing mechanism 4 also includes an ejection hydraulic cylinder 42 located on the side of the extruder 1 away from the positioning mechanism. The piston rod of the ejection hydraulic cylinder 42 forms an abutting fit with the inner liner. The function of the ejection hydraulic cylinder 42 is to eject the inner liner from the extruder 1 into the positioning groove 34 after the inner liner has been used.

[0033] Reference Figure 1 and Figure 2 Limit frames 22 are provided on both sides of the conveyor belt 21. The limit frames 22 can prevent the lining from deviating from the track during the transmission process and ensure that the lining can reach the designated position accurately.

[0034] The implementation principle of this embodiment is as follows: Through an automated transportation and positioning mechanism, rapid replacement of the liner is achieved, significantly improving production efficiency and reducing downtime. The conveyor belt 21 transports the liner to the positioning frame 3, and the positioning groove 34 on the positioning frame 3 ensures that the liner accurately enters the predetermined position. Then, the propulsion hydraulic cylinder 41 pushes the liner into the extruder 1 to begin the extrusion process; when the liner is used up, the ejection hydraulic cylinder 42 ejects the liner from the extruder 1. The entire process requires no manual intervention, greatly saving time and labor costs. Furthermore, the movable design of the positioning frame 3 allows the device to flexibly adapt to different production environments, improving the equipment's versatility and flexibility.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
