Abstract

This invention provides a special equipment for producing biodegradable high-performance fibers. Two discs are installed on both sides of the lower end of the hopper. A rotating shaft is rotatably mounted in the center of each disc. One end of the rotating shaft is oscillatingly connected to a support arm. Bearings are rotatably connected between the support arms. A clamping frame is provided on the side of the support arm near the disc. Top and bottom blades are oscillatingly connected to both ends of the bearing, respectively. The upper end of the top rod presses against the lower end of the sliding frame. The sliding frame drives the entire secondary track to move upward. Due to sliding inertia, the sliding rod inside the secondary track slides upward synchronously. The sliding rod drives the scraper to slide vertically. Through the sliding of the scraper, the material at the upper end of the scraper can flow downward, preventing material accumulation at the upper end of the scraper. Based on the above steps, it can be seen that the material at the lower end of the hopper can be fed evenly and slowly to the upper end of the hopper by the vertical sliding of the scraper, while preventing blockage.

Description

Technical Field

[0001] This invention relates to the field of knitting technology, and in particular to a special equipment for the production of biodegradable high-performance fibers. Background Technology

[0002] Biodegradable high-performance fibers are a type of fiber material with excellent performance that can be decomposed into harmless substances by microorganisms in the natural environment. In the processing, they are processed and extruded through a screw extruder. The dried and mixed biodegradable polymer raw materials are heated and melted to make them into a melt with good fluidity. The melt is then transported to the spinning assembly by the extrusion action of the screw, and the processing of biodegradable high-performance fibers is completed by the spinning assembly. This paper provides technical inspiration for screw extruders.

[0003] The research on screw extruders revealed the following problems:

[0004] Biodegradable high-performance fiber materials are usually in granular form before being heated and extruded. When a large number of granules enter the hopper of the screw extruder, a large amount of material accumulates inside the hopper. The material is prone to entering the screw extruder too quickly at the discharge port at the bottom of the hopper, making it difficult for the screw extruder to heat the material evenly. When the material at the bottom of the hopper is restricted, the material at the bottom of the hopper is prone to blockage. As a result, the screw extruder cannot achieve uniform feeding of the material at the top of the hopper while avoiding blockage at the bottom of the hopper.

[0005] Currently, the prior art, CN113882076B, discloses a yarn guiding device for the production of biodegradable fiber products. This device features an inner frame fitted to one side of the yarn hole, an airbag sealed at one end of the inner frame, and a sealing ring embedded in the inner groove of the inner frame. An mounting frame is also included; one end of the inner frame is threaded with a mounting bracket, and a one-way valve is threaded into the inner groove of one end of the mounting bracket. Air holes are provided on both sides of the contact surface between the mounting bracket and the inner frame. Through the inner frame, the one-way valve, and the airbag, the size of the yarn hole is significantly limited during use. Furthermore, the fan facilitates cleaning and enhances the static electricity removal effect. The mounting ring effectively limits the feed aperture during use.

[0006] This invention primarily solves the problem that screw extruders cannot achieve uniform feeding of material at the upper end of the hopper while avoiding blockage at the lower end of the hopper. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a dedicated device for producing biodegradable high-performance fibers, thereby resolving the issues described in the background section.

[0008] The purpose and effectiveness of the special equipment for producing biodegradable high-performance fibers of the present invention are achieved by the following specific technical means: a special equipment for producing biodegradable high-performance fibers includes an extruder, a motor is provided on one side of the extruder, a reducer is provided at one end of the motor, a screw is rotatably connected to the end of the motor near the reducer, and a hopper is connected through the upper end of the screw.

[0009] Furthermore, the extruder is placed entirely on the ground, and a heating coil is provided at the upper end of the extruder near the screw. The heating coil is connected to the power circuit via a power cord.

[0010] Furthermore, the screw is fitted with a shell, the hopper is installed on the upper end of the shell, and the motor drives the screw to rotate 360°.

[0011] Furthermore, both the motor and the reducer are connected to the power circuit via power lines.

[0012] Furthermore, discs are installed on both sides of the lower end of the hopper, and a rotating shaft is rotatably mounted on the middle of each disc. One end of the rotating shaft is swayably connected to a support arm, and bearings are rotatably connected between the support arms. A snap-fit ​​bracket is provided on the side of the support arm near the disc, and top blades and bottom blades are swayably connected to both ends of the bearings, respectively. A top rod is provided at the upper end of the support arm.

[0013] Furthermore, the rotating shaft, support arm, and bearing are matched together. The bearing extends laterally through the interior of the hopper, and the support arm and rotating shaft are combined in a "Z" shape. The bearing and the snap-fit ​​bracket are located on both sides of one end of the support arm.

[0014] Furthermore, the outer wall of the disc is provided with a sliding groove, which is arc-shaped with an arc angle of 90-120°. The side of the snap-fit ​​bracket is T-shaped, and one end of the snap-fit ​​bracket slides 360° inside the sliding groove.

[0015] Furthermore, the bottom blade is located at the lower end of the bearing, and the weight of the bottom blade is 100-200g greater than that of the top blade. Both the top blade and the bottom blade have grooves running through their inner sides. The grooves are rectangular and there are multiple grooves.

[0016] Furthermore, the top rods are arranged vertically, with the upper end of the top rods being semi-circular, and the upper end of the top rods extending to the upper end of the hopper interior.

[0017] Furthermore, the upper part of the hopper is provided with main tracks on both sides, a sliding frame slides through the inner side of the main tracks, the upper part of the sliding frame is provided with secondary tracks on both sides, a sliding rod slides through the inner side of the secondary tracks, and scrapers are provided on both sides of the sliding rod.

[0018] Furthermore, the main track and the auxiliary track are arranged vertically, and the sliding frame and the sliding rod slide vertically inside the main track and the auxiliary track, respectively.

[0019] Furthermore, the lower end of the sliding frame is perpendicularly pressed to the upper end of the top rod. When the top rod is not pressed to the lower end of the sliding frame, the sliding frame is at the lower end of the main track.

[0020] Furthermore, the scrapers are arranged horizontally, with multiple scrapers on both sides of the slide bar, and the scrapers are spaced 0.4-0.7cm apart.

[0021] Beneficial effects:

[0022] 1. After the material enters the hopper, it falls to the top of the top blade. When the weight of the material at the top of the top blade is greater than 200g, the top blade drives the bearing to rotate and swings downward. The bearing drives the support arm to rotate synchronously. Since the locking frame at one end of the support arm slides inside the groove of the disc, the swing angle of the support arm can be limited by the locking frame. When the support arm swings vertically, the support arm drives the top rod to move vertically.

[0023] 2. When the top blade swings downward, the material slides down from the top of the top blade. At this time, the top blade can swing back to its original position through the bearing. The support arms at both ends of the bearing move back to their original positions synchronously. By repeating the above steps, the material at the lower end of the hopper can be cleared by the swing of the top and bottom blades, avoiding the situation where the material is granular and accumulates at the lower end of the hopper, requiring manual clearing.

[0024] 3. The scrapers are arranged horizontally to lift the material at the top of the hopper, preventing the weight of the material at the top of the hopper from accumulating on top of the material at the bottom of the hopper. At the same time, the scrapers can separate the material and achieve slow feeding.

[0025] 4. When the push rod slides upward, the upper end of the push rod presses against the lower end of the sliding frame. The sliding frame drives the entire secondary track to move upward. Due to sliding inertia, the sliding rod on the inner side of the secondary track slides upward synchronously. The sliding rod drives the scraper to slide in a vertical direction. Through the sliding of the scraper, the material at the upper end of the scraper can be assisted to flow downward, avoiding the accumulation of material at the upper end of the scraper. Combining the above steps, it can be seen that the material at the lower end of the hopper can be fed evenly and slowly to the upper end of the hopper by the vertical sliding of the scraper, while preventing blockage.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0038] As attached Figure 1 To be continued Figure 9 As shown:

[0039] Example 1: A special equipment for producing biodegradable high-performance fibers includes an extruder 1, a motor 101 on one side of the extruder 1, a reducer 102 at one end of the motor 101, a screw 103 rotatably connected to the end of the motor 101 near the reducer 102, and a hopper 2 connected through the upper end of the screw 103.

[0040] The extruder 1 is placed on the ground. A heating coil is provided at the upper end of the extruder 1 near the screw 103. The heating coil is connected to the power circuit through a power cord.

[0041] The screw 103 is fitted with a shell, the hopper 2 is installed on the upper end of the shell, and the motor 101 drives the screw 103 to rotate 360°.

[0042] Both the motor 101 and the reducer 102 are connected to the power circuit via a power line. The reducer 102 can reduce the high speed of the motor 101 to the speed required by the screw 103, while increasing the torque to meet the power requirements of the screw 103 during the extrusion process.

[0043] In this process, the material enters the outer shell of the screw 103 through the hopper 2. The motor 101 drives the screw 103 to rotate 360°. The heating coil heats the material, which becomes a melt with good fluidity after heating. The material is then discharged from one end of the extruder 1 through the extrusion action of the screw 103, thus completing the extrusion process of the biodegradable high-performance fiber.

[0044] Example 2: Refer to the attached instruction manual Figure 3-8 It can be seen that the difference between Embodiment 2 and Embodiment 1 is that discs 204 are installed on both sides of the lower end of the hopper 2. A rotating shaft 201 is rotatably mounted in the middle of each disc 204. One end of the rotating shaft 201 is swayably connected to a support arm 202. A bearing 3 is rotatably connected between the support arms 202. A snap-fit ​​bracket 203 is provided on the side of the support arm 202 near the disc 204. The two ends of the bearing 3 are respectively swayably connected to a top blade 301 and a bottom blade 302. A top rod 205 is provided at the upper end of the support arm 202.

[0045] The components include: a rotating shaft 201, a support arm 202, and a bearing 3. The bearing 3 extends laterally through the interior of the hopper 2. The support arm 202 and the rotating shaft 201 are combined in a "Z" shape. The bearing 3 and the clamping bracket 203 are located on both sides of one end of the support arm 202. (See the attached instruction manual for details.) Figure 7 As shown;

[0046] The outer wall of the disc 204 has a groove, which is arc-shaped with an angle of 90-120°. The side of the snap-fit ​​bracket 203 is T-shaped, and one end of the snap-fit ​​bracket 203 slides 360° inside the groove. Please refer to the instruction manual for details. Figure 7 As shown;

[0047] The outer wall of the disc 204 is provided with a sliding groove. The sliding groove is arc-shaped with an arc angle of 90-120°. By limiting the shape of the sliding groove, the sliding angle of the snap-fit ​​bracket 203 can be limited, thereby limiting the swing angle of the support arm 202.

[0048] The bottom blade 302 is located at the lower end of the bearing 3. The weight of the bottom blade 302 is 100-200g greater than that of the top blade 301. Both the top blade 301 and the bottom blade 302 have grooves running through their inner sides. The grooves are rectangular and there are multiple grooves.

[0049] Since the weight of the bottom blade 302 is 100-200g greater than that of the top blade 301, when the weight of the material at the top of the top blade 301 is greater than 200g, the top blade 301 swings downward, and the top blade 301 drives the bottom blade 302 to swing upward through the bearing 3.

[0050] The top rods 205 are arranged vertically, and the upper end of the top rods 205 is set in a semi-circular arc shape, extending to the upper end of the inside of the hopper 2.

[0051] Wherein: After the material enters the interior of the hopper 2, the material falls to the upper end of the top blade 301. When the weight of the material at the upper end of the top blade 301 is greater than 200g, the top blade 301 drives the bearing 3 to rotate and the top blade 301 swings downward. The bearing 3 drives the support arm 202 to rotate synchronously. Since the snap-fit ​​bracket 203 at one end of the support arm 202 slides inside the groove of the disc 204, the swing angle of the support arm 202 can be limited by the snap-fit ​​bracket 203. When the support arm 202 swings in a vertical direction, the support arm 202 synchronously drives the top rod 205 to move in a vertical direction.

[0052] When the top blade 301 swings downward, the material slides down from the top of the top blade 301. Therefore, the top blade 301 can swing back to its original position through the bearing 3. The support arms 202 at both ends of the bearing 3 move back to their original positions synchronously. By repeating the above steps, the material at the lower end of the discharge port inside the hopper 2 can be cleared by the swing of the top blade 301 and the bottom blade 302, so as to avoid the situation where the material is granular and accumulates at the lower end of the hopper 2, requiring manual clearing.

[0053] Example 3: Refer to the appendix of the instruction manual Figure 6-9 It can be seen that the difference between Embodiment 3 and Embodiments 1 and 2 is that the upper part of the hopper 2 is provided with main rails 4 on both sides, the inner side of the main rails 4 is slidably connected with a sliding frame 401, the upper part of the sliding frame 401 is provided with secondary rails 402 on both sides, the inner side of the secondary rails 402 is slidably connected with a sliding rod 403, and the sliding rod 403 is provided with scrapers 404 on both sides.

[0054] Among them: the main track 4 and the auxiliary track 402 are arranged in a vertical direction, and the sliding frame 401 and the sliding rod 403 slide in a vertical direction inside the main track 4 and the auxiliary track 402 respectively;

[0055] The lower end of the sliding frame 401 is perpendicularly pressed to the upper end of the top rod 205. When the top rod 205 is not pressed to the lower end of the sliding frame 401, the sliding frame 401 is at the lower end of the main track 4.

[0056] The scrapers 404 are arranged horizontally, and multiple scrapers 404 are provided on both sides of the slide bar 403, with a spacing of 0.4-0.7cm between the scrapers 404;

[0057] By arranging the scrapers 404 horizontally, the material at the upper end of the hopper 2 can be lifted, preventing the overall weight of the material at the upper end of the hopper 2 from accumulating at the upper end of the material at the lower end of the hopper 2. At the same time, the separation by the scrapers 404 can achieve slow feeding.

[0058] The top end of the push rod 205 is set in a semi-circular arc shape, which makes it convenient for the push rod 204 to be pressed against the lower end of the sliding frame 401 when the support arm 202 drives the push rod 205 to tilt and swing in a vertical direction.

[0059] When the top rod 205 slides upward, the upper end of the top rod 205 presses against the lower end of the sliding frame 401. The sliding frame 401 drives the sub-rail 402 to move upward as a whole. Due to sliding inertia, the sliding rod 403 on the inner side of the sub-rail 402 slides upward synchronously. The sliding rod 403 drives the scraper 404 to slide in a vertical direction. Through the sliding of the scraper 404, the material at the upper end of the scraper 404 can be assisted to flow downward, avoiding the accumulation of material at the upper end of the scraper 404. According to embodiments 2 and 3, the material at the lower end of the hopper 2 can be fed evenly and slowly to the upper end of the hopper 2 by the vertical sliding of the scraper 404 while preventing blockage.
