[0029] Reference Figures 1 to 5This utility model provides a multi-channel extruder head for rubber extrusion equipment: it includes a head body 1 and a first discharge pipe 2. The first discharge pipe 2 is connected to the lower surface of the head body 1. Several second discharge pipes 3 are connected to the outer surface of the head body 1. Electronic valves are fixedly installed on the outer surface of the second discharge pipes 3. Discharge heads 10 are sleeved on the bottom ends of the first discharge pipes 2 and the second discharge pipes 3. Sealing rings are fixedly installed on the inner wall of the discharge heads 10.

The inner wall of the discharge head 10 is provided with a limiting groove that matches the limiting blocks 11. A rod 12 is inserted into the outer surface of the discharge head 10. The rod 12 passes through the outer surface of the discharge head 10. The outer surfaces of the first discharge pipe 2 and the second discharge pipe 3 are provided with insertion holes for inserting the rod 12. A pull block 13 is fixedly installed at the end of the rod 12 away from the discharge head 10. A tension spring 14 is sleeved on the outer surface of the rod 12. One end of the tension spring 14 is fixedly connected to the outer surface of the discharge head 10, and the other end of the tension spring 14 is fixedly connected to the pull block 13.
[0030] A fixing ring 4 is fixedly installed on the inner wall of the machine head body 1. A servo motor 5 is fixedly installed on the lower surface of the machine head body 1. A threaded rod 6 is fixedly installed at the output end of the servo motor 5. The threaded rod 6 passes through the lower surface of the machine head body 1 and extends into the interior of the machine head body 1. A sliding rod 7 is fixedly installed on the lower surface of the fixing ring 4. A movable ring 8 is slidably connected to the outer surface of the sliding rod 7. The upper surface of the movable ring 8 is threadedly connected to the threaded rod 6. A shielding ring 9 is fixedly installed on the upper surface of the movable ring 8. The arc-shaped outer wall of the shielding ring 9 is slidably connected to the inner wall of the machine head body 1.
[0031] By setting up the die head body 1, first discharge pipe 2, second discharge pipe 3, fixing ring 4, servo motor 5, threaded rod 6, sliding rod 7, movable ring 8, shielding ring 9, discharge head 10, limiting block 11, insertion rod 12, pull block 13 and tension spring 14, the function of quickly installing and disassembling the discharge head 10 is realized. This improves the fixing method of the discharge head 10 in the existing technology, making it more convenient when the discharge head 10 needs to be replaced, saving time and effort, and improving the practicality of the multi-channel extruder head.
[0032] A connecting assembly is provided at the top of the die head body 1. The connecting assembly includes an extrusion tube 15 and a connecting tube 16. The extrusion tube 15 is located at the top of the die head body 1, and the connecting tube 16 is fixedly installed at the bottom end of the extrusion tube 15. The connecting tube 16 is inserted into the die head body 1. Two positioning rings 17 are fixedly installed on the outer surface of the top of the die head body 1. A sealing gasket 18 is provided at the top of the die head body 1. A sealing ring 19 is fixedly installed on the lower surface of the sealing gasket 18. A positioning block 20 is fixedly installed at the top of the die head body 1. The sealing gasket 18 is sleeved on the outer surface of the positioning block 20, and the sealing ring 19 is sleeved on the outer surface of the connecting tube 16. A threaded sleeve 21 is slidably connected to the outer surface of the die head body 1 located between the two positioning rings 17. A threaded groove that meshes with the threaded sleeve 21 is opened on the outer surface of the bottom end of the extrusion tube 15.
[0033] By setting up the extrusion tube 15, connecting tube 16, positioning ring 17, sealing gasket 18, sealing ring 19, positioning block 20 and threaded sleeve 21, the function of quickly and conveniently installing the die head body 1 onto the extrusion tube 15 is realized. This improves the installation method of the die head body 1 in the prior art, so that when the die head body 1 is damaged, it can be quickly disassembled and reassembled, thus speeding up the replacement rate of the die head body 1 and further improving the practicality of the multi-channel extrusion die head.
[0034] Working principle: When installing the multi-channel extruder head onto the extrusion tube 15, first place the sealing gasket 18 on the top of the head body 1, so that the sealing gasket 18 is fitted on the outer surface of the positioning block 20, and at the same time, the sealing ring 19 slides into the interior of the head body 1. Then, place the head body 1 directly below the extrusion tube 15 and move the head body 1 upward so that the connecting tube 16 is inserted into the interior of the head body 1, and at the same time, the sealing ring 19 is fitted on the outer surface of the connecting tube 16. When the head body 1 contacts the extrusion tube 15, pull the threaded sleeve 21 upward and rotate the threaded sleeve 21 so that the threaded sleeve 21 is connected to the extrusion tube 15 through the threaded groove, thus completing the installation of the multi-channel extruder head.
[0035] When the rubber extruder is in use, the molten rubber enters the interior of the die head body 1 through the extrusion pipe 15, then flows into the interior of the first discharge pipe 2 and the second discharge pipe 3, and finally is extruded from the interior of the die head body 1 through the discharge head 10. When it is necessary to close the second discharge pipe 3, the servo motor 5 is started. When the servo motor 5 is running, it drives the threaded rod 6 to rotate inside the die head body 1, thereby driving the movable ring 8 to move. Under the action of the slide rod 7, the movable ring 8 rises, and at the same time, the blocking ring 9 slides upward along the inner wall of the die head body 1. When the blocking ring 9 blocks the discharge port of the second discharge pipe 3, the second discharge pipe 3 is closed. By reversing the above operation, the closure of the second discharge pipe 3 can be released. At the same time, the unobstructed state of a single second discharge pipe 3 can also be controlled by an electronic valve.
[0036] When it is necessary to replace the discharge head 10, pull the pull block 13 to stretch and deform the tension spring 14, and at the same time drive the insertion rod 12 to extend away from the discharge head 10. After the insertion rod 12 slides out from the inside of the insertion hole, the fixing of the discharge head 10 is released. Then pull the discharge head 10 down so that the discharge head 10 slides down along the outer wall of the first discharge pipe 2 or the second discharge pipe 3. The limiting block 11 slides inside the limiting groove. After the discharge head 10 is detached from the first discharge pipe 2 or the second discharge pipe 3, take out the new discharge head 10 and reverse the above operation to fix the new discharge head 10 to the first discharge pipe 2 or the second discharge pipe 3, thus completing the replacement of the discharge head 10.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
