Abstract
Description
Technical Field
[0001] This invention relates to the field of chemical fiber processing equipment technology, specifically to chemical fiber protective raw material melt drawing processing equipment. Background Technology
[0002] The preparation of synthetic fiber protective materials requires high-temperature melt extrusion and stretching into filaments. This type of processing is mostly accomplished using screw extrusion devices in conjunction with molding dies. In continuous processing, solid synthetic fiber granules or powder raw materials need to be stored in the feeding assembly first, and then fall continuously downwards into the high-temperature barrel under gravity for heating and melting.
[0003] During operation, the heat generated by the barrel is conducted upwards to the feed constriction area. The solid fiber raw material in the lower channel becomes sticky upon heating, causing the materials to press against each other and form solid material arches at the narrow feed point. This bridging phenomenon directly cuts off the path of the upper raw material. Conventional fiber drawing equipment relies on manual hammering of the outer wall to break these arches. This operation is highly dependent on real-time manual inspection, and delays in handling this can lead to short-term material shortages inside the barrel.
[0004] Some existing equipment has added a rotating stirring component inside the feed hopper to force feeding. The internal stirring structure continuously scrapes the solid chemical fiber raw materials, generating debris and dust, and also occupies the basic feeding passage space. The fixed built-in blades do not have an effective breaking effect on the stubborn adhesion in the wall area. The interruption of feeding induces the chemical fiber filaments formed at the extrusion end to have diameter fluctuations and loosening and breakage.
[0005] Therefore, this invention proposes a melt-drawing processing equipment for chemical fiber protective raw materials to overcome the shortcomings of existing technologies. Summary of the Invention

Rotating shaft two is rotatably connected to the right side of the moving blocks. The two rotating shaft two are respectively connected to the corresponding rotating shaft one through the connecting rod. Striking rods are fixedly connected to adjacent sides of the two moving blocks.
[0009] Preferably, the replacement mechanism includes a fixed plate, which is fixedly connected to the rear side of the heating ring. A servo motor is fixedly connected to the left side of the fixed plate. The output end of the servo motor passes through the fixed plate and is fixedly connected to a movable rod.

[0011] Preferably, a transmission wheel is fixedly connected to the left side of the outer wall of both screw one and screw two, and the two transmission wheels are connected by a transmission belt.
[0012] Preferably, a bolt is threaded onto one side of the hollow rod, and one end of the bolt passes through the hollow rod and the insert rod in sequence.
[0013] Preferably, the holes on one side of the multiple spinnerets are all of different sizes, and the size of the sealing ring matches the internal size of the retaining ring.
[0014] Preferably, a U-shaped frame is fixedly connected to the right side of the outer wall of the base, an electric push rod is fixedly connected to the top inner side of the U-shaped frame, a hollow frame is fixedly connected to the output end of the electric push rod, and a floating roller is rotatably connected inside the hollow frame.

[0018] This invention provides a melt-drawing processing device for chemical fiber protective raw materials. It has the following beneficial effects:
[0019] 1. This invention features an eccentric connecting rod striking structure driven by a power component at the feed end. During equipment operation, the material falls in a loose state due to high-frequency mechanical vibration by reciprocating the striking of the outer wall of the feed assembly. This solves the problem of particle bridging and accumulation blockage that often occurs in the feed inlet area of solid raw materials, and maintains the stability of continuous feeding in the internal heating extrusion process.
[0020] 2. This invention integrates a multi-station rotary switching module on the side of the extrusion end. It utilizes a rotating bracket to pre-install multiple sets of spinneret assemblies with different specifications of holes. When facing the need to change the diameter of chemical fiber filaments, the corresponding spinneret is directly driven by the motor to be screwed into the snap-fit station on the front side of the extrusion end. This eliminates the tedious operation of manually disassembling and reassembling the die head mold in the traditional shutdown state, shortens the time for specification switching, and enhances the processing adaptability of the equipment.
[0021] 3. This invention adds a vertical lifting adjustment mechanism to the traction and winding path after the fiber drawing is formed. During continuous fiber drawing operation, the height of the floating roller is changed by the linear drive component. This dynamically compensates for the deviation of the traction allowance generated during the synchronous operation of the external winding equipment. This ensures that the chemical fiber filaments in the cooling and shaping stage maintain a relatively constant tension, preventing the filaments from breaking due to local loosening and detachment from the roller or overload. This ensures the uniformity of the thickness of the finished chemical fiber protective material. Attached Figure Description

[0035] Please refer to Figure 4 , Figure 5 and Figure 6 A striking mechanism 4 is installed on the top of the heating ring 6, and a replacement mechanism 5 is installed on the rear side of the heating ring 6. The striking mechanism 4 includes a fixed frame 41 fixedly connected to the top of the outer wall of the heating ring 6.

[0036] A fixed shaft 46 is fixedly connected to the left end face of the worm gear 45 at an eccentric position. A rotating shaft 47 is rotatably connected to the outside of the fixed shaft 46 via a bearing. Limiting frames 48 are fixedly connected to the inner walls of the front and rear sides of the fixed frame 41. A moving block 49 is slidably connected inside the limiting frame 48.

The end of the striking rod 412 extends to the outer wall of the feed frame 12 and contacts the side wall of the feed frame 12. The servo motor 42 drives the striking rod 412 to reciprocate and continuously strike the outer wall of the feed frame 12 through the eccentric transmission cooperation between the worm gear 45 and the connecting rod 411.
[0037] Please refer to Figure 1 , Figure 4 and Figure 8 A U-shaped plate 13 is fixedly connected to the left end face of the barrel 3.

A transmission belt 18 is tensioned between the two transmission wheels 17 and the two transmission wheels 17 are connected by the transmission belt 18. The stepper motor 14 provides rotational power to drive screw 15 to rotate. The outer transmission wheel 17 of screw 15 drives the outer transmission wheel 17 of screw 2 16 to rotate synchronously through the transmission belt 18. Screw 15 and screw 2 16 are used to extrude and convey the molten chemical fiber raw material inside the barrel 3.
[0038] Please refer to Figure 1 , Figure 2 and Figure 7 A replacement mechanism 5 is fixedly connected to the rear outer wall of the heating ring 6. The replacement mechanism 5 includes a fixing plate 51. The front end face of the fixing plate 51 is fixedly connected to the rear outer wall of the heating ring 6.

The output shaft of the servo motor 52 passes through the plate body of the fixing plate 51 and is fixedly connected to a movable rod 53. Hollow rods 54 are fixedly connected radially around the outer cylindrical surface of the movable rod 53. A plug rod 55 is movably inserted into the hollow rod 54. A through threaded hole is opened on the side wall of the hollow rod 54. A fastening bolt 59 is threaded in the hole. The inner end of the bolt 59 passes through the side wall of the hollow rod 54 and the outer wall of the plug rod 55 in sequence. The bolt 59 is used to lock the position of the plug rod 55 relative to the hollow rod 54 and adjust its length.

A retaining ring 58 is fixedly connected to the left end face of the barrel 3. The outer diameter of the sealing ring 56 matches the internal space of the retaining ring 58 to ensure that the sealing ring 56 is locked into the retaining ring 58 to maintain the sealing at the connection. The holes on the end faces of the multiple spinnerets 57 are all of different sizes. The servo motor 52 drives the movable rod 53 to rotate, which drives the insert rods 55 distributed around the periphery to switch angles and send the sealing ring 56 on the outside of the spinneret 57 with the corresponding hole size into the retaining ring 58. The spinneret 57 is used to form the melt extruded inside the barrel 3 into chemical fiber filaments of a set diameter.
[0040] For the control circuit settings of drive components such as servo motor 52 and stepper motor 14, those skilled in the art use conventional motor driver methods to implement them. Their specific internal electrical structures are well-known in the art and will not be described in detail here.
[0041] Please refer to Figure 1 , Figure 2 and Figure 3 A U-shaped frame 7 is fixedly connected to the right side of the outer wall of the base 1. An electric push rod 8 is fixedly connected to the top wall of the inner side of the U-shaped frame 7 by bolts. The output end of the electric push rod 8 extends vertically downward and is fixedly connected to a hollow frame 9. A floating roller 10 is placed horizontally inside the hollow frame 9. The two ends of the floating roller 10 are rotatably connected to the left and right sides of the inner wall of the hollow frame 9 through bearings. The electric push rod 8 provides linear driving force to drive the hollow frame 9 to move vertically up and down along the inner space of the U-shaped frame 7. The movement of the hollow frame 9 drives the horizontally arranged floating roller 10 inside to move up and down synchronously to change its height. The outer wall of the floating roller 10 is used to receive the extruded chemical fiber filaments and to guide the filaments and dynamically compensate for tension in conjunction with the external winding equipment.
[0042] Please refer to Figure 1A control panel 11 is fixedly connected to the front outer wall of the U-shaped frame 7. The control panel 11 integrates a microprocessor chip and a power supply module. The output end of the control panel 11 is electrically connected to the top servo motor 42 of the striking mechanism 4, the side servo motor 52 of the changing mechanism 5, the outer heating ring 6 of the barrel 3, the top electric push rod 8 of the U-shaped frame 7, and the side stepper motor 14 of the U-shaped plate 13 through control wires. The control panel 11 is equipped with interactive buttons and a data display screen on the outside. The control panel 11 is used to receive operation commands and send action start / stop signals and power adjustment parameters to each independent drive component.
[0043] Working principle: The operator first pours the chemical fiber protective material into the feed frame 12, which is connected to the top left side of the heating ring 6. The servo motor 42 at the top of the striking mechanism 4 is started by the control panel 11 on the front side of the U-shaped frame 7. The output shaft of the servo motor 42 drives the worm gear 43 fixedly connected at the bottom to rotate. The worm wheel 45 meshing with the outside of the worm gear 43 rotates synchronously. The worm wheel 45 drives the rotating shaft 47 on the periphery of the left fixed shaft 46 to rotate. The rotating shaft 47 pulls the rotating shaft 410 to move through the connecting rod 411 on the outside. The rotating shaft 410 drives the moving block 49 connected to the right to slide back and forth along the inside of the limiting frame 48. The striking rod 412 fixedly connected to the end of the moving block 49 follows the movement trajectory of the moving block 49 and continuously strikes the outer wall of the feed frame 12. The high-frequency reciprocating striking action keeps the chemical fiber material inside the feed frame 12 in a loose state and falls quickly, preventing the material from accumulating, bridging and blocking the feeding channel.
[0044] The chemical fiber raw material smoothly falls into the barrel 3. The control panel 11 activates the heating ring 6 and the stepper motor 14 on the left side of the U-shaped plate 13. The heating ring 6 dissipates heat to heat the chemical fiber raw material inside the barrel 3 to a high temperature, bringing it to a molten state. The output end of the stepper motor 14 drives the screw 15 to rotate. The drive wheel 17 on the outer wall of the screw 15 drives the drive wheel 17 on the outer wall of the screw 2 16 to rotate synchronously through the drive belt 18. The screws 15 and 2 16 push and convey the molten chemical fiber raw material forward inside the barrel 3. The melt is compressed and acts as a force. The spinneret 57 is extruded into a thin, long chemical fiber filament by passing through the inside of the retaining ring 58 at the left end of the barrel 3 and engaging the sealing ring 56 and the spinneret 57 through a micro-hole. When changing the drawing specification, the control panel 11 sends a control signal to drive the servo motor 52 on the side of the changing mechanism 5 to rotate at a set angle. The output shaft of the servo motor 52 drives the movable rod 53 to rotate, so that the spinneret 57 with the corresponding specification micro-hole at the end of the hollow rod 54 and the outer sealing ring 56 are re-aligned and sent into the retaining ring 58, realizing the rapid switching and docking of spinnerets 57 with different apertures.
[0045] The extruded chemical fiber filaments are pulled to the right and around the top surface of the floating roller 10 inside the hollow frame 9. The end of the chemical fiber filaments is connected to the external winding equipment and the winding operation is started. During the stretching and winding process, the extension and retraction length of the electric push rod 8 at the top of the U-shaped frame 7 is adjusted by the control panel 11. The output end of the electric push rod 8 pushes and pulls the hollow frame 9 to move up and down in the vertical direction. The hollow frame 9 drives the internal floating roller 10 to change its vertical height position. The floating roller 10 applies a guiding support force to the chemical fiber filaments and compensates for the tightness deviation during the winding process, so that the chemical fiber filaments maintain a dynamic tension state during the cooling and winding stage to ensure the processing and molding quality of the chemical fiber protective raw material.
