Description

Technical Field

[0001] This utility model relates to the field of optical cable production equipment technology, and in particular to an extruder for optical cable production materials. Background Technology

[0002] A cable is an electrical or signal transmission device, usually composed of several or several groups of conductors. In the cable production process, the materials required for optical cable production (such as plastics, rubber, etc.) are extruded and molded by an optical cable production material extruder to wrap around the optical cable core, forming the sheath or insulation layer of the optical cable.

[0003] In the prior art, there is an extruder (publication number: CN221161422U) that includes an extruder body and an extruder head. One of the extruder body and the extruder head is provided with a snap-fit ​​component, and the other has a snap-fit ​​groove that matches the snap-fit ​​component. The snap-fit ​​component has a first state and a second state. When the snap-fit ​​component is configured in the first state, it snaps into the snap-fit ​​groove. When the snap-fit ​​component is pressed to the second state, it disengages from the snap-fit ​​groove. Although the snap-fit ​​component and snap-fit ​​groove of this extruder can engage the extruder body and the extruder head, when the extruder head needs to be replaced, simply pressing the snap-fit ​​component to disengage it from the snap-fit ​​groove allows for easy separation of the extruder head from the extruder. This design facilitates the removal of the extruder head from the extruder body, providing convenience for replacing extruder heads of different specifications.

[0004] However, extruder heads are generally heavy, and they need to be moved by crane or manpower during replacement, which is very time-consuming and reduces the efficiency of extruder head replacement, thereby affecting the production efficiency of the extruder. Utility Model Content

One end of the rotating rod extends into the switching frame and connects to the rotating disk. A connecting cylinder is installed on the extruder body, communicating with the switching frame. A sealing component is provided on the connecting cylinder, with a portion of the sealing component extending to the extruder head. The sealing component is driven by an electric push rod and is used to seal the connection between the extruder head and the connecting cylinder.

[0007] Preferably, the inner diameter of the mounting groove is the same as the outer diameter of the sealing ring, a positioning groove is provided on the inner wall of the mounting groove, and a positioning block is installed on the outer wall of the sealing ring, the positioning block being adapted to the positioning groove.

[0011] Preferably, the multiple extruder heads are evenly distributed in a ring.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] By setting multiple extruder heads, the extruder heads can be quickly replaced when the working needs of the extruder body need to be changed, under the action of the rotating motor, rotating disk and rotating rod, ensuring the working efficiency of the extruder body. Moreover, this replacement method does not require disassembling the extruder heads, reducing manpower consumption.

[0014] By setting a connecting cylinder and a sealing ring on the connecting cylinder, and by using an electric push rod and a push frame, the extruder head and the connecting cylinder can have better sealing performance under the combined action of the sealing ring, ensuring the normal operation of the extruder body.

[0015] By employing a threaded rod and threaded cylinder connection method, and with the assistance of clamping blocks and clamping frames, the extruder head can be quickly disassembled and assembled, improving the ease of extruder head replacement. Attached Figure Description

The rotary motor 12 can drive the rotary rod 13 to rotate, which in turn drives the rotating disk 10 to rotate, and then drives the extruder head 4 to rotate, thus completing the switching of the extruder head 4.

[0023] A connecting cylinder 3 is installed on the extruder body 1. The connecting cylinder 3 is connected to the switching frame 2. The end of the connecting cylinder 3 away from the extruder body 1 is on the same plane as one side of the inner wall of the switching frame 2. A sealing assembly is provided on the connecting cylinder 3, and part of the sealing assembly extends to the extruder head 4. The sealing assembly is driven by an electric push rod 9 and is used to seal the connection between the extruder head 4 and the connecting cylinder 3. The sealing assembly consists of a sealing ring 5, a sealing ring 7, a push frame 8, and an electric push rod 9. The sealing ring 5 is installed on the extruder head 4, and the sealing ring 7 is slidably installed on the connecting cylinder 3. The pusher frame 8 is slidably sleeved on the connecting cylinder 3. The pusher frame 8 is connected to the sealing ring 7. The connecting cylinder 3 has a receiving groove. The sealing ring 7 is located in the receiving groove and slides in contact with the inner wall of the receiving groove. The pusher frame 8 is composed of a sliding ring and four pillars. The sliding ring is sleeved on the outer wall of the connecting cylinder 3. The four pillars are installed in a ring on one side of the sliding ring. The other end of each of the four pillars extends into the receiving groove and is connected to the sealing ring 7. All four pillars are slidably connected to the connecting cylinder 3. The electric push rod 9 is installed on the extruder body 1. The telescopic shaft of the electric push rod 9 is connected to the pusher frame 8.

[0024] A retaining frame 15 is installed on the sealing ring 5, and a retaining block 16 is slidably installed on the rotating disk 10. An avoidance groove is provided on the inner wall of the mounting groove 11. The retaining block 16 is located in the avoidance groove and slides in contact with the inner wall of the avoidance groove. The retaining block 16 is adapted to the retaining frame 15. When performing the retaining operation, one side of the retaining block 16 extends into the retaining frame 15 and is tightly connected to the retaining frame 15. A threaded cylinder 17 is installed on the retaining block 16. A threaded rod 18 is rotatably installed on the rotating disk 10.

[0026] In this embodiment, before use, multiple extruder heads 4 need to be installed into the switching frame 2. The specific installation operation is as follows: insert one end of the extruder head 4 into the installation through groove 11, and make one side of the extruder head 4 contact the inner wall of one side of the switching frame 2. Then, by rotating the rotating wheel 19, the threaded rod 18 is driven to rotate. Under the action of the threaded cylinder 17, the clamping block 16 is pushed to move and enter the clamping frame 15, thereby completing the installation of the extruder head 4. Similarly, multiple extruder heads 4 can be installed at one time.

[0027] In use, select the appropriate extruder head 4. Under the action of the rotating motor 12, rotating rod 13 and rotating disk 10, drive the corresponding extruder head 4 to one end of the connecting cylinder 3. Then start the electric push rod 9 to push the push frame 8 to move, and then push the sealing ring 7 to move, so that one side of the sealing ring 7 extends into the sealing groove 6. This completes the connection between the extruder head 4 and the connecting cylinder 3, which facilitates the normal operation of the extruder body 1. Similarly, according to the above method, the extruder head 4 can be replaced in time when the working requirements of the extruder body 1 change, ensuring the working efficiency of the extruder body 1. At the same time, this switching does not require manual labor, reducing manpower consumption.
