Description

Technical Field

[0001] This invention relates to the field of extruder technology, and more particularly to an extruder head for cable material. Background Technology

[0002] The cable extruder head is a crucial component of the extruder, primarily responsible for uniformly guiding the molten plastic through the die to form the desired cable sheath or other plastic tubing products. It is one of the key components in the extrusion production line that directly impacts product quality and production efficiency.

[0003] The prior art publication CN104890211A provides a cable material extrusion coating die head. This technology features an ingenious and compact overall structure, strong practicality, and ensures a reasonable plastic flow channel within the die head, eliminating dead zones where plastic accumulates and guaranteeing the quality of the extruded product. The technology includes an electric heater positioned above the die head body to provide appropriate heating, further ensuring product quality. A sealing gasket is also included to further ensure the seal between the guide rod and the die head body. This technology is low-cost, safe to operate, stable in operation, and highly efficient, making it suitable for large-scale application.

[0004] In the extrusion production of cable materials, removing the freshly extruded plastic is a crucial operation. In the early stages of extrusion, due to changes in temperature and pressure, the plastic may undergo partial degradation or aging, leading to a decline in its performance. Current technology is not convenient for automatically removing the plastic in the early stages, requiring manual removal. High-temperature plastics have high heat energy, and if operators come into contact with them, it may cause burns or other safety accidents.

[0005] In summary, the existing technology lacks a technology for automatic removal of initial material from the extruder head of cable material. Summary of the Invention

[0014] Preferably, a tension spring A is fixedly connected to one end of the movable frame, and the other end of the tension spring A is fixedly connected to the movable seat. A sliding groove is provided on the lower side of the movable frame, and a slider is slidably fitted on the inner wall of the sliding groove. A tension spring B is fixedly connected to the bottom end of the slider, and the other end of the tension spring B is fixedly connected to the bottom end of the movable frame. An adjusting rack is fixedly connected to the top end of the slider, and the adjusting rack is meshed with a gear for transmission.

This can effectively avoid operators coming into contact with high-temperature materials, thereby reducing the risk of work-related accidents and ensuring the safety of the production process. In the extrusion production of cable materials, it can effectively improve production efficiency, ensure product quality, optimize the production process, and ultimately reduce costs and improve production stability. 2. By setting a push rod, the initial material removal plate rotates while being pulled out. In conjunction with the blade, it can cut the cable material attached to the initial material removal plate and allow the initial cable material to fall smoothly into the waste collection box for collection. The automated method of initial material removal and cutting through the push rod and blade can effectively improve production efficiency, reduce manual intervention, ensure safety, reduce waste, and improve product quality consistency. 3. By setting plug-in blocks on the waste material seat, quick disassembly and assembly of the waste material seat are realized, reducing the time cost of cleaning the waste material seat and thus improving the overall operating efficiency of the production line. At the same time, by setting dust cover, the opening of the extruder head can be sealed when the extruder head is not in use, which can effectively prevent external dust and dirt from entering the extruder head, thereby reducing the wear and contamination of the internal components of the equipment.

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figures 1-8 The cable material extruder head shown includes a mounting frame 1, an extruder head 2 fixedly connected to the mounting frame 1, a waste material seat 3 inserted into one side of the bottom end of the mounting frame 1, a movable seat 4 slidably fitted inside the waste material seat 3, an adjustment mechanism 5 rotatably connected to the movable seat 4, a movable seat 6 rotatably connected to the adjustment mechanism 5, a primary material processing mechanism 7 on the movable seat 6, a movable frame 8 rotatably connected to one end of the primary material processing mechanism 7, and a push rod 9 rotatably connected inside the movable seat 6.

[0021] like Figure 3 As shown, the mounting frame 1 has a mounting hole 101 at the bottom. A motor 102 is fixedly connected to the mounting frame 1. A dust cover 103 is fixedly connected to the output end of the motor 102. The dust cover 103 is slidably contacted with the opening on one side of the extruder head 2.

[0022] like Figure 3As shown, an extrusion chamber 201 is provided inside the extruder head 2, and a pipe joint 202 is fixedly connected through the inner wall of the extrusion chamber 201.

[0023] like Figure 4 As shown, a plug-in block 301 is fixedly connected to one end of the waste base 3. Limiting blocks 302 are slidably fitted on the inner walls of both the upper and lower ends of the plug-in block 301. An inclined surface is opened on the outer end of the limiting block 302. A spring 303 is fixedly connected to the inner end of the limiting block 302. The other end of the spring 303 is fixedly connected to the inner wall of the plug-in block 301. The plug-in block 301 is movably plugged into the inner wall of the mounting hole 101. An electric push rod 304 is fixedly connected to one inner wall of the waste base 3. The output end of the electric push rod 304 is fixedly connected to the movable seat 4. A fixed rack 305 is fixedly connected to the other inner wall of the waste base 3.

[0024] like Figure 5 As shown, the adjusting mechanism 5 includes a worm gear 501, which is rotatably connected to the movable seat 4. An adjusting wheel 502 is fixedly connected to the bottom end of the worm gear 501, and the adjusting wheel 502 meshes with a fixed rack 305. Worm wheels 503 are meshed on both sides of the worm gear 501, and the worm wheels 503 are rotatably connected to the movable seat 4. A connecting rod assembly 504 is fixedly connected to one end of each worm wheel 503, and the other end of the connecting rod assembly 504 is rotatably connected to the movable seat 6. When the movable seat 4 continues to move, the adjusting wheel 502 meshes with the fixed rack 305, thereby causing the worm gear 501 connected to the adjusting wheel 502 to rotate. This allows the worm gear 501 to drive the worm wheels 503 on both sides to rotate, which in turn drives the connecting rod assembly 504 to rotate, causing the connecting rod assembly 504 to move the movable seat 6 downwards.

[0025] like Figure 6 As shown, two blades 601 are fixedly connected on one side of the movable seat 6 in a symmetrical structure.

[0026] like Figure 6 As shown, the initial material processing mechanism 7 includes a movable rod 701, which is slidably connected to the movable seat 6. The outer wall of the movable rod 701 is slidably in contact with one end of the blade 601. One end of the movable rod 701 is fixedly connected to an initial material removal plate 702, the outer wall of the initial material removal plate 702 is slidably connected to the inner wall of the extruder head 2, and the other end of the movable rod 701 is rotatably connected to the movable frame 8. A gear 703 is fixedly connected to one end of the movable rod 701 that passes through the movable frame 8.

[0027] By setting up a primary material processing mechanism 7, the primary material removal plate 702 is inserted into the extruder head 2. After a portion of the primary material is extruded from the extruder head 2, the primary material is removed when the primary material removal plate 702 is pulled out, thus replacing manual removal. This effectively avoids operators coming into contact with high-temperature materials, thereby reducing the risk of workplace accidents and ensuring the safety of the production process. In cable material extrusion production, it can effectively improve production efficiency, ensure product quality, optimize the production process, and ultimately reduce costs and improve production stability.

[0028] like Figure 7 As shown, a tension spring A801 ​​is fixedly connected to one end of the movable frame 8, and the other end of the tension spring A801 ​​is fixedly connected to the movable seat 6. A slide groove 802 is provided on the lower side of the movable frame 8, and a slider 803 is slidably fitted on the inner wall of the slide groove 802. A tension spring B804 is fixedly connected to the bottom end of the slider 803, and the other end of the tension spring B804 is fixedly connected to the bottom end of the movable frame 8. An adjusting rack 805 is fixedly connected to the top end of the slider 803, and the adjusting rack 805 is meshed with a gear 703 for transmission. When the push shaft 901 moves in the slide groove 802, the push shaft 901 will contact and squeeze the slider 803, thereby causing the adjusting rack 805 connected to the slider 803 to move. At this time, the adjusting rack 805 will drive the movable rod 701 connected to the gear 703 to rotate, so that the movable rod 701 drives the connected initial material removal plate 702 to rotate, allowing the initial material to fall into the waste seat 3 for collection.

[0029] like Figure 8 As shown, a push shaft 901 is fixedly connected between the top ends of the push rod 9. The push shaft 901 is slidably engaged with the inner wall of the slide groove 802. The outer wall of the push shaft 901 is in movable contact with the slider 803. A universal joint 902 is fixedly connected to one side of the bottom end of the push rod 9. The universal joint 902 is rotatably connected to the inner wall of the movable seat 6. A transmission wheel 903 is fixedly connected to one end of the universal joint 902. A transmission rack 904 is meshed on one side of the transmission wheel 903. The transmission rack 904 is slidably engaged with the inner wall of the movable seat 6. A triangular block 905 is fixedly connected to the outer end of the transmission rack 904. The triangular block 905 is in slidable contact with the inner wall of the waste seat 3. When the movable seat 6 moves down, the triangular block 905 will contact the inner wall of the waste seat 3, and the triangular block 905 will drive the connected transmission rack 904 to move. At this time, the transmission rack 904 will drive the universal joint 902 connected to the transmission wheel 903 to rotate, so that the universal joint 902 can drive the connected push rod 9 to rotate, so that the push shaft 901 at the other end of the push rod 9 slides in the slide groove 802, thereby pushing the movable frame 8 to move.

[0030] Working principle: When extruding cable material, the molten cable material is first injected into the extrusion chamber 201 through the pipe joint 202 and extruded. When a portion of the initial material is extruded, the electric push rod 304 drives the moving seat 4 to move, so that the initial material removal plate 702 can be moved out from the extruder head 2. At this time, the initial material removal plate 702 will remove the initial material. Then, as the movable seat 4 continues to move, the adjusting wheel 502 will mesh with the fixed rack 305, which will drive the worm 501 connected to the adjusting wheel 502 to rotate, so that the worm 501 can drive the worm wheels 503 on both sides to rotate, so that the worm wheels 503 can drive the connected linkage group 504 to rotate, so that the linkage group 504 drives the movable seat 6 to move down. When the movable seat 6 moves down, the triangular block 905 will contact the inner wall of the waste seat 3, and the triangular block 905 will drive the connected transmission rack 904 to move. At this time, the transmission rack 904 will drive the universal joint 902 connected to the transmission wheel 903 to rotate, so that the universal joint 902 can drive the connected push rod 9 to rotate, so that the push shaft 901 at the other end of the push rod 9 will slide in the slide groove 802, thereby pushing the movable frame 8 to move. When the movable frame 8 moves, it will drive the initial material removal plate 702 connected to the movable rod 701 to approach the movable seat 6. At this time, under the action of the blade 601 on the movable seat 6, the cable material attached to the movable rod 701 can be cut off. At the same time, when the push shaft 901 moves in the slide 802, the push shaft 901 will contact and squeeze the slider 803, which will cause the adjusting rack 805 connected to the slider 803 to move. At this time, the adjusting rack 805 will drive the movable rod 701 connected to the gear 703 to rotate, so that the movable rod 701 will drive the connected initial material removal plate 702 to rotate, so that the initial material can fall into the waste seat 3 for collection. Then, by pressing the two limiting blocks 302, the limiting blocks 302 are retracted into the plug block 301, and the plug block 301 can be removed from the inner wall of the mounting hole 101 to clean the initial material in the waste seat 3. When the extruder head 2 is not in use, the motor 102 drives the connected dust cover 103 to rotate, so that the dust cover 103 can seal the opening of the extruder head 2.
