Description

Technical Field

[0001] The invention belongs to the technical field of nylon (PA) material production technology, and in particular relates to a feeding system for the nylon (PA) material production technology. Background Art

[0002] Nylon (i.e. polyamide) material has low density, good processing performance, good wear resistance and self-lubrication, good heat insulation and thermal stability, good corrosion resistance, high resilience, excellent electrical properties, and high rigidity. The finished product does not require anti-corrosion treatment. It has been used as an engineering material to replace non-ferrous metals in various fields. In the production process, the granulator first melts the nylon material through an extruder, and then the melted nylon material is extruded from the shaping device to form a long strip of nylon belt. The nylon belt then enters the cooling water tank to cool and shape the nylon belt. The cooled nylon belt enters the cutting machine to form granules.

[0003] When feeding the extruder, the nylon raw material is directly poured into the feed bin. The nylon raw material feeds the extruder under the action of gravity. Excessive accumulation of nylon raw material in the feed bin may cause the feed bin to be blocked.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0033] The present invention provides a feeding system for a nylon (PA) material production process, such as Figure 1-6 As shown, it includes a feed bin 1, a fixed shaft 2 is fixedly connected to the top of the feed bin 1, a reduction motor 3 is fixedly connected to the top of the fixed shaft 2, an auxiliary plate 4 is sleeved on the outer surface of the fixed shaft 2, a number of feed pipes 5 are arranged between the auxiliary plate 4 and the feed bin 1, both ends of the feed pipe 5 are respectively fixedly connected to the auxiliary plate 4 and the feed bin 1, and through holes matching the feed pipe 5 are provided on the surface of the auxiliary plate 4 and the top of the feed bin 1, a rotating shaft 9 is rotatably inserted inside the fixed shaft 2, one end of the rotating shaft 9 is fixedly connected to the output end of the reduction motor 3, and the other end of the rotating shaft 9 passes through the fixed shaft 2 and is inserted into the inside of the feed bin 1, and the rotating shaft 9 is located on the inner surface of the feed bin 1 and is fixedly connected to a spiral blade 10, and the spiral blade 10 is located below the position of the feed hopper 8;

[0034] A rotating ring 6 is rotatably sleeved on the top of the fixed shaft 2, and a mounting bracket 7 is fixedly connected to the outside of the rotating ring 6. A number of feed hoppers 8 are arranged in the middle of the mounting bracket 7. The feed hoppers 8 and the feed pipe 5 are arranged in a ring relative to the center of the fixed shaft 2. A transmission mechanism is provided between the rotating ring 6 and the rotating shaft 9.

[0035] When feeding the extruder producing nylon material, the mixed nylon raw material is poured into the corresponding number of feed hoppers 8, the reduction motor 3 drives the rotating shaft 9 to rotate, and the spiral blade 10 rotates in the feed bin 1. The rotation of the rotating shaft 9 drives the rotating ring 6 to rotate through the transmission mechanism, and the mounting frame 7 rotates accordingly. When the mounting frame 7 rotates, it drives several feed hoppers 8 to rotate. When the feed hopper 8 moves to the top of the corresponding feed pipe 5, the nylon raw material falls into the feed bin 1 through the feed pipe 5 and enters the extruder from the feed bin 1. If too much nylon raw material is fed, it will gather in the feed bin 1. The rotating spiral blade 10 pushes the nylon raw material downward and stirs it to avoid blockage in the feed bin 1 due to excessive feeding of nylon raw material.

[0036] like Figure 1-6 As shown, a flip plate 11 is rotatably inserted at the bottom of the feed hopper 8, and a rotating rod 12 is fixedly connected to the middle of the flip plate 11. One end of the rotating rod 12 passes through the feed hopper 8 and extends to the outside, and the end of the rotating rod 12 is fixedly connected to a pushing block 14. The surface of one end of the rotating rod 12 located in the feed hopper 8 is sleeved with a torsion spring 13. The auxiliary plate 4 is provided with a movable groove 15 on one side of several feed pipes 5, and a gear bar 16 is movably inserted inside the movable groove 15. The gear bar 16 is arc-shaped, and the movable groove 15 matches it. One end of the gear bar 16 is sloped, and the bottom of the pushing block 14 is an arc-shaped surface. A rotating rod 17 is rotatably inserted at the bottom of the gear bar 16, and the bottom of the rotating rod 17 passes through the movable groove 15 and extends to the outside of the auxiliary plate 4, and the end of the rotating rod 17 is fixedly connected to an adjusting knob 18. A thread is provided on the surface of the rotating rod 17, and the rotating rod 17 is threadedly sleeved at the insertion position of the auxiliary plate 4.

[0037] Before feeding the extruder for producing nylon material, turn the adjusting knob 18 to drive the rotating rod 17 to rotate, the rotating rod 17 rotates and moves upward and drives the gear block 16 to gradually extend from the movable groove 15. Since the rotating rod 17 and the auxiliary plate 4 are threaded at the joint position, the position of the gear block 16 is fixed by the rotating rod 17. When the reduction motor 3 works and drives the mounting frame 7 to rotate through the rotating ring 6, several feed hoppers 8 rotate accordingly. When the feed hopper 8 moves to the position of the gear block 16, one end of the gear block 16 is set as a slope and the push block The bottom of 14 is an arc-shaped surface. The bottom surface of the feed hopper 8 pushes the push block 14 to rotate 90 degrees. The push block 14 changes from the original vertical state with the gear block 16 to a parallel state. When the push block 14 rotates, the rotating rod 12 rotates, and the torsion spring 13 is twisted and elastically deformed. The flip plate 11 rotates 90 degrees and is perpendicular to the bottom of the feed hopper 8. The nylon raw material in the feed hopper 8 loses the obstruction of the flip plate 11 and falls into the feed pipe 5. The feed hopper 8 continues to move. When the feed hopper 8 leaves the position of the gear block 16, the push block 14 loses the resistance of the feed hopper 8. The torsion spring 13 is reset to drive the rotating rod 12 to reset, and the pushing block 14 returns to the vertical state with the gear bar 16. The flip plate 11 rotates back to its original position and is parallel to the bottom of the feed hopper 8. At this time, the flip plate 11 closes the bottom of the feed hopper 8. The nylon raw material loaded into the feed hopper 8 again will not leak from the bottom of the feed hopper 8. Under the cooperation of the gear bar 16 and the pushing block 14, the nylon material in the feed hopper 8 is released into the feed pipe 5. Then, the feeding amount of the feed pipe 5 can be limited by the number of gear bars 16 used. If the nylon raw material The accumulation in the feed bin 1 can reduce the number of working gear blocks 16, and thus reduce the number of feed pipes 5 used, so that the raw materials entering the feed bin 1 are reduced. When different numbers of feed pipes 5 are used, the nylon raw materials entering the feed bin 1 are different, and the feeding quantity and rate of the nylon raw materials can be controlled, so that the feed bin 1 feeds the extruder in a quantitative manner, avoiding the accumulation of nylon raw materials in the feed bin 1. At the same time, the quantity of raw materials in the feed bin 1 can be maintained, avoiding the need to clean up the raw materials in the feed bin 1 in large quantities due to extruder failure.

[0038] like Figure 1-6 As shown, the transmission mechanism includes a working groove 19, and a driving gear 20 is rotatably inserted inside the working groove 19. The driving gear 20 is fixedly connected to the rotating shaft 9. The rotation center of the driving gear 20 is on the same straight line as the rotation center of the rotating shaft 9 and the rotating ring 6. Driven gears 21 are meshed on both sides of the driving gear 20. An annular tooth 22 is provided on the inner side of the rotating ring 6, and the annular tooth 22 is meshed with two driven gears 21.

[0039] When the reduction motor 3 drives the rotating shaft 9 to rotate, the driving gear 20 rotates accordingly, and the rotation of the driving gear 20 drives the driven gears 21 on both sides to rotate, and the rotation of the driven gear 21 drives the annular teeth 22 to rotate, and the rotating ring 6 drives the mounting bracket 7 to rotate. The setting of the transmission mechanism enables the reduction motor 3 to drive the mounting bracket 7 to rotate while connecting the mounting bracket 7 to the fixed shaft 2. The transmission efficiency of the transmission mechanism is high, and less energy is wasted during the transmission process. At the same time, it does not affect the driving of the rotating shaft 9 by the reduction motor 3, so that the spiral blades 10 stir the feed bin 1.

[0040] like Figure 1-6 As shown, a rotating shaft 23 is rotatably inserted in the middle of the feed pipe 5, and both ends of the rotating shaft 23 are rotatably inserted in the inside of the feed pipe 5. A plurality of partition plates 24 are fixedly connected to the surface of the rotating shaft 23, and both sides of the partition plates 24 are in contact with the inner wall of the feed pipe 5. The plurality of partition plates 24 are arranged in a ring relative to the center of the rotating shaft 23, and one side of the top partition plate 24 is in contact with the flip plate 11.

[0041] When the nylon raw material enters the feed pipe 5, the raw material impacts the partition plate 24 on one side, and the partition plate 24 drives the rotating shaft 23 to rotate. The falling raw material pushes the partition plate 24 to rotate and then falls into the feed bin 1. When the feed hopper 8 drives the flip plate 11 perpendicular to the bottom of the feed hopper 8 to move to a certain position, the bottom of the flip plate 11 contacts one of the partition plates 24 and pushes it in the opposite direction. The rotating shaft 23 and the partition plate 24 will stop rotating. The raw material accumulates on the two partition plates 24 and flows out and then falls into the feed bin 1. After the flip plate 11 leaves the position of the partition plate 24, the accumulated nylon raw material will push the partition plate 24 drives the rotating shaft 23 to rotate in the opposite direction for half a circle, and the nylon raw material gradually falls into the feed bin 1. If too much nylon raw material accumulates and enters the feed pipe 5, the fallen nylon raw material cannot push the partition plate 24 to make it rotate with the rotating shaft 23. When the flip plate 11 passes through the partition plate 24, the bottom of the flip plate 11 pushes the partition plate 24, and the partition plate 24 rotates in a small range to stir the feed pipe 5 to avoid clogging of the raw material in the feed pipe 5. At the same time, the raw material first contacts the partition plate 24 when passing through the feed pipe 5, reducing the impact force of the raw material directly on the spiral blade 10 and increasing the service life of the spiral blade 10.

[0042] For example, it is particularly important that, in one embodiment, see Figures 7 and 8To facilitate the rapid entry of the nylon raw material into the feed pipe 5, a slope 161 is formed on one end of the top surface of the stop bar 16 to guide the flip plate 11 to flip and move to the top surface of the stop bar 16. A step portion 163 is formed on the end of the stop bar 16 away from the slope 161. The upper surface of the step portion 163 is lower than the top surface of the middle portion of the stop bar 16. The surface of the step portion 163 is provided with a plurality of serrated grooves 165. When the flip plate 11 is about to separate from the stop bar 16, that is, when it is about to seal the bottom of the feed hopper 8, the push block 14 moves on the plurality of serrated grooves 165 of the step portion 163, thereby causing the flip plate 11 to rotate and vibrate at a high frequency, thereby vibrating the nylon raw material off it and ultimately sealing the bottom of the feed hopper 8. This prevents some nylon raw material from being contaminated between the side wall of the flip plate 11 and the bottom side wall of the feed hopper 8, thereby affecting the sealing effect.

[0043] In one embodiment, please refer to Figure 9 To prevent the nylon raw material from being blocked by the sidewalls of the flip plate 11 when the flip plate 11 is vertical, the flip plate 11 includes a main body and a sealing assembly 110. The sealing assembly 110 is tightened on one side of the main body that follows the forward movement of the feed hopper 8, and the other side is provided with an arc-shaped corner portion 113. The bottom surface of the arc-shaped corner portion 113 forms an arc-shaped surface 115, which is located at the lower portion of the sidewall of the flip plate 11. When the flip plate 11 is flipped to the vertical position, the arc-shaped corner portion 113 is located on the upper side. Due to the provision of the arc-shaped surface 115, the sidewalls of the flip plate 11 are prevented from blocking the nylon raw material. The arc-shaped surface 115 guides the nylon raw material to slide down, preventing it from being blocked. The lower arrow indicates the forward movement direction of the flip plate 11, and the upper arrow indicates the rotation direction of the rotating rod 12.

[0044] For example, the sealing component 110 includes an elastic leather bag 1121, an upper side plate 1122, a middle plate 1123 and a lower side plate 1124. The upper side of the elastic leather bag 1121 is connected to the upper side wall of the main body of the flip plate 11, and the lower side plate 1121 is connected to the lower side wall of the main body of the flip plate 11. The upper side plate 1122, the middle plate 1123 and the lower side plate 1124 are arranged from top to bottom respectively. The upper side plate 1122, the middle plate 1123 and the lower side plate 1124 are all rotatably connected to the middle part of the side wall of the main body of the flip plate 11. A stop block is protruding from the middle part of the side wall of the flip plate 11, and the stop block is stopped at the lower side of the middle plate 1123 so that the middle plate 1123 can only rotate upward. When the middle plate 1123 abuts the stop block 1123, it forms an angle of 3-5 degrees with the horizontal plane, causing the middle plate 1123 to tilt upward. The distance between the sidewalls of the main body and the sidewalls of the bottom opening of the feed hopper 8 is defined as a first distance. The width of the middle plate 1123 is slightly greater than the first distance. The widths of the upper and lower plates 1122 and 1124 are equal and both greater than the width of the middle plate 1123, where the width is measured perpendicular to the central axis of the rotating rod 12. Both the upper and lower plates 1122 and 1124 form an angle relative to the middle plate 1123. The upper side of the elastic bag 1121 is stretched straight by the upper plate 1122, while the lower side of the elastic bag 1121 is stretched straight by the lower plate 1124. The middle sidewall of the elastic bag 1121 is clamped between the end wall of the middle plate 1123 and the sidewalls of the bottom opening of the feed hopper 8, thereby achieving a seal. For example, the elastic leather bag 1121 is closed. When the nylon material is supported on the flip plate 11 (i.e., when the flip plate 11 is closed), the slightly upward-tilted middle plate 1123 can rely on the sidewalls of the bottom opening of the feed hopper 8 to relatively firmly support the nylon material above. The upper side plate 1122 can also rely on its own weight and the weight of the nylon material to tilt and support the sidewalls of the bottom opening of the feed hopper 8, thereby completely sealing the bottom opening with its long length and providing strong support from the sidewalls of the bottom opening.

[0045] During the turning process of the turning plate 11, the sealing assembly 110 is turned downward due to the force. During the turning process, the upper side plate 1122 and the middle plate 1123 rotate upward relative to the main body, so that the sealing assembly 110 can be smoothly turned downward and pass over the side wall of the bottom opening of the feed hopper 8. The provision of the sealing assembly 110 can achieve a better sealing effect on the one hand, and on the other hand, its tilted angle can provide greater support strength by relying on the side wall of the bottom opening.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
