[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0016] like Figures 1 to 6 As shown, this utility model discloses a quick replacement device for a squeeze roller assembly. The technical solution adopted includes a mobile trolley 1 and a lifting trolley 6. A track frame 4 is installed on the mobile trolley 1 through a height adjustment component 2. The height of the track frame 4 from the ground is adjusted through the height adjustment component 2. The height adjustment assembly 2 includes an adjusting bolt 21 and a fixing bolt 22. The adjusting bolt 21 is provided on the track frame 4. Under the action of the adjusting bolt 21, the longitudinal distance between the track frame 4 and the moving trolley 1 is adjusted. The moving trolley 1 is also provided with a fixing bolt 22 to limit the adjustment bolt 21.

[0017] The track frame 4 has a through first threaded hole, in which the adjusting bolt 21 is engaged. The moving trolley 1 has a second threaded hole coaxial with the first threaded hole, in which the fixing bolt 22 is engaged. The adjusting bolt 21 has a through hole through which the fixing bolt 22 passes.

[0018] like Figure 5 and Figure 6The diagram shows the height adjustment component 2 in both its non-working and working states. The height adjustment component 2 quickly aligns the lifting slide rail 3 on the track frame 4 with the support slide rail 12 on the squeeze roller frame 9, making the two sets of tracks a whole and ensuring that the squeeze roller assembly 8 can move directly to the designated position along the track.

[0019] The track frame 4 is equipped with a lifting slide rail 3, and a lifting trolley 6 is slidably connected to the lifting slide rail 3. Two lifting trolleys 6 form a group to lift and transport the extrusion roller assembly 8. The lifting slide rail 3 is made of unequal angle steel, and two lifting slide rails 3 form a group for supporting the lifting trolley 6.

[0020] The track frame 4 is also equipped with a quick-release pin 5. The quick-release pin 5 adopts a pull ring steel ball structure and can be purchased on the market. It will not be described in detail here. The quick-release pin 5 is used to limit the movement of the lifting trolley 6.

[0021] The lifting trolley 6 includes a body 63 and wheels 61. The wheels 61 are installed on both sides of the body 63. The width of the body 63 is adapted to the spacing between the two sets of lifting slide rails 3.

[0022] The vehicle body 63 and the extrusion roller assembly 8 face each other with a protrusion 62, and the protrusion 62 is provided in multiple sets for limiting the position of the extrusion roller assembly 8.

[0023] The working principle of this utility model: When installing the squeeze roller assembly 8 Place the squeeze roller assembly 8 to be replaced on the lifting trolley 6. The protrusion 62 on the lifting trolley 6 limits the squeeze roller assembly 8 to prevent it from sliding off the body 63 of the lifting trolley 6. The omnidirectional wheels at the bottom of the trolley 1 drive the squeezing roller assembly 8 to move the trolley 1 to the squeezing roller frame 9. The height of the track frame 4 is adjusted by the height adjustment assembly 2 (adjusting bolt 21 and fixing bolt 22 cooperate), so that the lifting slide rail 3 on the track frame 4 is aligned with the support slide rail 12 of the squeezing roller frame 9 to form a continuous track, providing a path for the movement of the lifting trolley 6. Remove the quick-release pin 5 on the track frame 4 to release its restriction on the lifting trolley 6, push the squeezing roller assembly 8 to move towards the squeezing roller frame 9, and the wheel 61 rolls on the lifting slide rail 3 and the support slide rail 12, driving the squeezing roller assembly 8 to move to the designated position. Place the lifting connecting plate 7 to connect the two sets of squeezing roller assemblies 8 into a whole through the lifting connecting plate 7; open the air inlet valve of the cylinder 10, and control the extension end of the cylinder 10 to extend through the squeezing roller control box, so that the extension end connector of the cylinder 10 corresponds to the pin hole of the bearing seat, and connect and limit the two through the quick release pin 5, control the cylinder 10 to retract, and lift the two sets of squeezing roller assemblies 8 together through the lifting connecting plate 7, so that the two sets of squeezing roller assemblies 8 are separated from the lifting trolley 6; After the squeezing roller assembly 8 is lifted by the cylinder 10 to detach from the lifting trolley 6, the lifting trolley 6 is pulled back onto the moving trolley 1 along the track to avoid interfering with subsequent fixing operations. The extension end of the control cylinder 10 extends and, once in position, the lifting connecting plate 7 is removed; the squeezing roller assembly 8 is fixed and limited, completing the installation and connection of the squeezing roller assembly 8 with the production line equipment; the squeezing roller assembly 8 is now in a usable state on the production line.

[0024] When disassembling the squeeze roller assembly 8, the installation steps are reversed as described above, and the squeeze roller assembly 8 can be disassembled.
