Description

Technical Field

[0001] This application relates to the technical field of plastic flat yarn production, and in particular to a plastic flat yarn drawing, cooling and cleaning tank system. Background Technology

[0002] The production process of plastic flat filaments mainly involves melting plastic at high temperatures, then extruding the molten fluid into a molding die using an extruder to form the desired plastic flat filaments. To ensure good mechanical properties and flatness, the filaments typically enter a cooling and setting stage immediately after extrusion. A cooling and cleaning tank is a commonly used cooling device in the plastic flat filament drawing process. The cooling and cleaning tank is equipped with guide rollers. By winding the extruded plastic flat filaments around the guide rollers, they are guided into the cooling and cleaning tank for cooling, while also cleaning impurities adhering to the surface of the plastic flat filaments.

[0003] Existing cooling and cleaning tanks are usually fixed. However, the optimal temperature for plastic flat yarns to enter the water varies during the production process of different specifications of plastic flat yarns. Therefore, the required distance from the plastic flat yarns from extrusion molding to entering the cooling tank also varies. With the height of the cooling and cleaning tank fixed, it is impossible to flexibly adjust the height and position of the cooling and cleaning tank according to production needs, which limits production efficiency and product quality. Summary of the Invention

[0004] To facilitate the adjustment of the height and position of the cooling and cleaning tank and improve production efficiency, this application provides a cooling and cleaning tank system for plastic flat filament drawing.

[0006] A plastic flat filament drawing cooling and cleaning tank system includes a frame, a base, a cooling and cleaning tank body, a horizontal sliding mechanism, and a vertical lifting mechanism. The base is slidably mounted on the frame. The horizontal sliding mechanism can drive the base to move along the plastic flat filament drawing direction. The cooling and cleaning tank body is mounted on the base. The vertical lifting mechanism can drive the cooling and cleaning tank body to move up and down.

[0007] By adopting the above technical solution, the horizontal sliding mechanism can drive the base to move along the stretching direction of the plastic flat wire, and the vertical lifting mechanism can drive the cooling and cleaning tank body to move up and down.

When the two clamping plates are close to each other, the magnets and the iron sheets attract each other. The lower surface of both clamping plates is provided with limiting grooves for engaging the limiting strips, and the limiting grooves are respectively opened at both ends of the clamping plates corresponding to the two limiting strips. When the two clamping plates are spaced apart along the length direction of the positioning rods, a receiving cavity is formed between the two clamping plates and the two positioning rods to allow all plastic flat wires to pass downwards.

[0015] By adopting the above technical solution, the combination of positioning seat and fixing bolts realizes the detachable installation of clamping assembly on the cooling cleaning tank body. The positioning rod can be used to support the clamping plate, and the limiting strip and limiting groove can guide the sliding direction of the clamping plate. By sliding the two clamping plates and fixing them with magnets and iron sheets, all plastic flat wires can be clamped and fixed conveniently and quickly.

[0016] Optionally, the guide roller is slidably disposed within the cooling and cleaning tank body, and the cooling and cleaning tank body is provided with a driving member for driving the guide roller to slide up and down; the guide roller includes a central shaft and a rotating outer roller rotatably disposed outside the central shaft, and the driving member is capable of driving the central shaft to slide up and down.

[0017] By adopting the above technical solution, the guide rollers can slide up and down, allowing the plastic flat filaments to be drawn horizontally.

[0019] By adopting the above technical solution, the coordinated use of slider, chute, drive screw, drive motor and guide rod realizes the smooth up and down sliding and precise control of the guide roller; this driving method is simple and reliable, has low maintenance cost, and improves the stability and durability of the system.

[0020] Optionally, a partition is provided at one end of the cooling cleaning tank body, forming a second water storage tank between the partition and the inner wall of the cooling cleaning tank body. A water outlet is provided on the upper side wall of the partition, and a water outlet plate is provided on the partition wall. The water outlet plate and the partition form a first water storage tank. The first water storage tank and the second water storage tank are connected through the water outlet.

The drain pipe is connected to the water inlet of the water pump, and the water outlet of the water pump is connected to the water inlet pipe through a flexible hose.

[0021] By adopting the above technical solution and incorporating structures such as baffles, water outlet plates, filters, and grooves, water circulation and filtration within the cooling and cleaning tank are achieved, ensuring the cleanliness of the cleaning water and its cooling effect.

[0023] By adopting the above technical solution, the central shaft has an internal hollow structure and is connected to the main water supply pipe through a connecting pipe, thus realizing the function of supplying water to the rotating outer roller. This design allows the cooling water to fully cool the rotating outer roller, thereby improving the cooling efficiency and effect on the plastic flat yarn.

[0024] Optionally, a wire splitting mechanism is provided at one end of the cooling cleaning tank body away from the positioning component.

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] This application discloses a cooling and cleaning tank system for drawing plastic flat filaments. (Refer to...) Figure 1 The cooling and cleaning tank system includes a frame 1, a base 13, a cooling and cleaning tank body 2, a horizontal sliding mechanism 3, and a vertical lifting mechanism 4. The frame 1 is a frame structure, including a rectangular frame at the bottom and vertically extending, spaced rectangular columns. A guide roller assembly guides the extruded plastic flat filaments between the two columns. Horizontal and vertical bars are intersecting within the rectangular frame at the bottom of the frame 1. The base 13 is a rectangular seat, and the cooling and cleaning tank body 2 is a hollow tank with an open top. The base 13 is mounted on the rectangular frame at the bottom of the frame 1, and the cooling and cleaning tank body 2 is mounted on the frame 1. One end of the cooling and cleaning tank body 2 is the filament inlet 11, and the other end is the filament outlet. After the plastic flat filaments are formed, they fall downwards along the guide roller assembly through the filament inlet 11 into the cooling and cleaning tank body 2. The cooling and cleaning tank body 2 is filled with cooling water, which cools the plastic flat filaments before they are discharged from the filament outlet 12. Simultaneously, the cooling water also cleans the plastic flat filaments.

[0041] Reference Figure 1 and Figure 2In this embodiment, the horizontal sliding mechanism 3 includes a guide rail 31, a first cylinder 32, and a drive block 33. The guide rail 31 is disposed between the lower surface of the base 13 and the frame 1, and extends along the length direction of the cooling cleaning tank body 2, so that the base 13 can slide along the length direction of the cooling cleaning tank body 2. The first cylinder 32 is fixed in the rectangular frame at the bottom of the frame 1, and the drive block 33 is welded to the lower surface of the base 13. The telescopic shaft end of the first cylinder 32 is connected to the drive block 33 to drive the base 13 to move horizontally on the frame 1. In other embodiments, the first cylinder 32 can also be replaced with a hydraulic cylinder, telescopic rod, or other linear drive device as needed.

[0042] Reference Figure 1 and Figure 2 In this embodiment, the vertical lifting mechanism 4 includes a second cylinder 41 and a rod 42. The second cylinder 41 is a pneumatic telescopic cylinder, with its telescopic shaft vertically arranged and connected to the bottom of the cooling cleaning tank body 2. To improve stability, the second cylinder 41 can be arranged on opposite diagonals of the cooling cleaning tank body 2. The rod 42 can be rectangular or cylindrical, fixed to the lower surface of the cooling cleaning tank body 2, and can be arranged on another set of diagonals of the cooling cleaning tank body 2. The base 13 has a slot 131 for the rod 42 to slide up and down.

[0043] Activating the first cylinder 32 can drive the cooling cleaning tank body 2 to move horizontally, and activating the second cylinder 41 can drive the cooling cleaning tank body 2 to move up and down, thereby adjusting the position of the plastic flat wire entering the cooling cleaning tank body 2. By flexibly adjusting the height and position of the cooling cleaning tank body 2, it can adapt to different production needs, improving production efficiency and product quality.

[0044] Reference Figure 1 and Figure 3 In this embodiment, a guide roller 5 is further provided inside the cooling and cleaning tank body 2. The guide roller 5 extends along the width direction of the cooling and cleaning tank body 2, and multiple guide rollers 5 are spaced apart along the length direction of the cooling and cleaning tank body 2. When the plastic flat wire falls into the cooling and cleaning tank body 2, the plastic flat wire is controlled to sequentially wind around the multiple guide rollers 5, so that the plastic flat wire is stretched along the length direction of the cooling and cleaning tank body 2 under the guidance of the guide rollers 5.

[0045] Reference Figure 1 and Figure 3 Because the plastic flat filaments are at a high temperature when they first fall into the cooling and cleaning tank body 2, it is difficult, inconvenient, and time-consuming for operators to guide them by hand around the guide rollers 5. Each auxiliary stretching also generates a large amount of waste filaments. In order to facilitate the stretching of the plastic flat filaments and enable them to quickly wrap around the corresponding guide rollers 5, the cooling and cleaning tank system also includes a clamping assembly 6 and a positioning assembly 7.

[0046] Reference Figure 3 and Figure 4 In this embodiment, the positioning component 7 is located at the wire inlet 11, and two sets of positioning components 7 are arranged along the width direction of the cooling cleaning tank body 2. The positioning component 7 includes a positioning seat 71, a positioning rod 72, a limiting strip 73, and a fixing bolt 74. The positioning seat 71 is an inverted "U"-shaped structure, with its opening facing downwards to engage with the upper end of the side wall of the cooling cleaning tank body 2. The fixing bolt 74 is threaded through the side wall of the positioning seat 71 and abuts against the outer side wall of the cooling cleaning tank body 2, thereby fixing the positioning seat 71 to the cooling cleaning tank body 2. The positioning rod 72 is a rectangular rod, fixed to the upper surface of the positioning seat 71, and extends into the cooling cleaning tank body 2 along its length direction. The limiting strip 73 is integrally formed on the upper surface of the positioning rod 72, and is a rectangular strip structure that extends along the length direction of the positioning rod 72.

[0047] Reference Figure 3 and Figure 4 In this embodiment, the clamping component 6 is detachably mounted on the positioning component 7. Specifically, the clamping component 6 includes a clamping plate 61, a magnet 62, and an iron sheet 63. The clamping plate 61 is a rectangular flat plate structure, while the magnet 62 and the iron sheet 63 are sheet-like structures. One clamping plate 61 has magnets 62 embedded at both ends, and the other clamping plate 61 has iron sheets 63 embedded at both ends. A limiting groove is also provided on the lower surface of the clamping plate 61. When the clamping plate 61 is placed on the positioning rod 72, the limiting strip 73 is engaged in the limiting groove, thereby allowing the clamping plate 61 to slide stably along the extension direction of the limiting strip 73. Further preferably, a buffer pad 611 is embedded on the side of the two clamping plates 61 that is close to each other. The buffer pad 611 is made of high-temperature resistant rubber to prevent damage to the plastic flat wire. Optionally, the side wall of one of the buffer pads 611 facing the other clamping plate 61 can also be wavy to hold and accommodate the plastic flat wire.

[0048] In use, the two clamping plates 61 are first set at both ends of the positioning pin. At this time, a receiving cavity is formed between the two clamping plates 61 and the two positioning rods 72 for the plastic flat wire to pass downward. When the plastic flat wire is formed and falls into the cooling and cleaning tank body 2, all the plastic flat wires can fall into the receiving cavity. At this time, the two clamping plates 61 are controlled to slide closer to each other. Through the magnetic attraction of the magnet 62 and the iron plate 63, the two clamping plates 61 are pressed against each other and the plastic flat wire is clamped between the buffer pads 611 of the two clamping plates 61. The operator only needs to control the two clamping plates 61 and move the clamping plates 61 around each guide roller 5 according to the required path to complete the drawing work of the plastic flat wire. Not only is the drawing efficiency high and the safety hazard small, but the clamping plate 61 fixation method does not require all the flat wires to be squeezed into a ball for operation, which helps to quickly adjust the position of the plastic flat wires and make them evenly wound on the guide roller.

[0049] Reference Figure 3 and Figure 5 In an optional embodiment, the guide roller is further slidably disposed within the cooling and cleaning tank body 2, and the cooling and cleaning tank body 2 is provided with a driving member 21 for driving the guide roller 5 to slide up and down. Specifically, the guide roller 5 includes a central shaft 51 and a rotating outer roller 52 rotatably disposed outside it. Both ends of the central shaft 51 are fixed with sliders 53, which are preferably T-shaped, but can also be dovetail-shaped or rectangular in other embodiments. The side wall of the cooling and cleaning tank body 2 is provided with a groove for the sliders 53 to slide up and down.

[0050] The driving component 21 includes a driving screw 211, a driving motor 212, and a guide rod 213. The driving screw 211 rotates vertically on the side wall of the cooling and cleaning tank body 2 and is threaded through the slider 53. The driving motor 212 is preferably fixed to the upper surface of the cooling and cleaning tank body 2, and the output shaft of the driving motor 212 extends vertically downward and is connected to the driving screw 211. The guide rod 213 is fixed vertically to another side wall of the cooling and cleaning tank body 2, and another slider 53 passes through the guide rod 213. When the driving motor 212 is started, the driving screw 211 rotates, causing the slider 53 to slide up and down, thus moving the central shaft 51 up and down.

[0051] Reference Figure 6 When stretching is required, first start the drive motor 212 to adjust all guide rollers 5 upwards or downwards to state A. At this time, all plastic flat filaments are held by clamps 61 and passed through the middle of all guide rollers. Then, start the drive motor 212 again to move the guide rollers 5 up and down to state B. During the movement of the guide rollers 5, the plastic flat filaments are automatically tightened, and the stretching of the plastic flat filaments is completed in the predetermined manner; that is, the stretching efficiency is improved, and the stretching effect is also improved. Furthermore, when the water temperature in the cooling and cleaning tank body 2 rises due to long-term use, adjusting the position of the guide rollers 5 up and down can increase the distance that the plastic flat filaments pass through in the cooling water, thereby increasing the immersion time and improving the cooling effect. There is no need to stop the machine to readjust the stretching method, which can effectively improve the production quality.

[0052] Reference Figure 1 and Figure 3In this embodiment, a baffle 22 is provided at one end of the cooling cleaning tank body 2 near the inlet 11, forming a second water storage tank 221 between the baffle 22 and the inner wall of the cooling cleaning tank body 2. An outlet is provided on the wall of the baffle 22, and an outlet plate 23 is provided outside the outlet. The outlet plate 23 and the baffle 22 enclose each other to form a first water storage tank 231. The first water storage tank 231 and the second water storage tank 221 are connected through the outlet. A filter screen 24 is provided at the outlet. When cooling water passes through the filter screen 24, impurities carried in the cooling water can be filtered by the filter screen 24. A groove is provided on the upper end of the distal side wall of the outlet plate 23 for water flow. Multiple grooves are provided along the extension direction of the side wall of the outlet plate 23. The grooves help control the rate at which cooling water flows into the first water storage tank. It should be noted that the outlet needs to be located at the upper end of the baffle 22 to match the water level height of the cooling cleaning tank body 2.

[0053] Reference Figure 3 and Figure 4 Furthermore, a drain pipe 25 and a water inlet pipe are installed on the outer wall of the cooling cleaning tank body 2. The drain pipe 25 is connected to the second water storage tank 221. A water pump 26 is installed on the outer wall of the cooling cleaning tank body 2, and the drain pipe 25 is connected to the water inlet of the water pump 26. The water outlet of the water pump 26 is connected to the water inlet pipe via a flexible hose. This design allows the cooling water to be recycled back into the cooling cleaning tank body 2 after being filtered by the filter screen 24, thus improving cooling efficiency and reducing water waste. The filter screen 24 also effectively removes impurities, ensuring the cleanliness of the cooling water and improving the quality of the plastic flat yarn. It should be noted that the water inlet of the water pump 26 is also connected to an external water pipe, allowing water to enter from the outside. The water pump 26 can be controlled to draw water from the second water storage tank or from the outside.

[0054] Reference Figure 5 and Figure 7 In an optional embodiment, the end of the inlet pipe facing into the cooling cleaning tank body 2 is further connected to a main water supply pipe 27. The central shaft 51 has an internal hollow structure, and a connecting pipe 511 is fixedly mounted on the side wall of the end of the central shaft 51. A water supply hose 28 is connected between the connecting pipe 511 and the main water supply pipe 27, and the water supply hose 28 is arranged in a one-to-one correspondence with the guide roller 5. A first water outlet hole 512 is provided on the side wall of the central shaft 51 located inside the rotating outer roller 52. Multiple first water outlet holes 512 can be provided, and they are preferably provided in the middle position of the central shaft 51. Second water outlet holes 521 are provided at both ends of the rotating outer roller 52.

[0055] This design allows cooling water to enter the central shaft 51 of all guide rollers 5 through the water delivery hose 28, and then be delivered to the area between the rotating outer roller 52 and the central shaft 51 through the first water outlet 512. This allows for rapid cooling of the rotating outer roller 52. Furthermore, the contact between the plastic flat wires and the sidewall of the rotating outer roller 52 enhances the cooling effect on the plastic flat wires. Finally, the cooling water is sprayed out through the second water outlet 521 on the rotating outer roller 52. The spray point is located around the plastic flat wires, allowing for direct cooling and further improving cooling efficiency.

[0056] Reference Figure 1 and Figure 3 In this embodiment, the cooling cleaning tank body 2 is further provided with a wire splitting mechanism 8 at one end where the wire outlet 12 is located. The wire splitting mechanism 8 includes two parallel mounting plates 81, a bolt assembly 82 fixed to the side wall of the cooling cleaning tank body 2, and a wire splitting plate 83 disposed between the two mounting plates 81. Specifically, the upper end of the mounting plate 81 is bent to form a horizontal plate, and its main body is placed against the inner wall of the cooling cleaning tank body 2. The horizontal plate portion is located above the side wall of the cooling cleaning tank body 2. The bolt assembly 82 includes a bolt and two nuts, wherein the bolt can pass through the horizontal plate portion and be threaded downward to the upper surface of the cooling cleaning tank body 2. The two lock nuts are respectively located on the lower surface of the horizontal plate and the upper surface of the cooling cleaning tank body 2, assisting in positioning the mounting plate 81. At the same time, multiple threaded grooves are spaced along the length direction on the upper surface of the side wall of the cooling cleaning tank body 2 to facilitate adjustment of the position of the mounting plate 81.

[0057] The wire separating plate 83 extends along the width direction of the cooling and cleaning tank body 2, and its two ends are fixed to the mounting plate 81 by bolts or other means. The upper surface of the wire separating plate 83 has a number of wire separating teeth spaced along its length. This structural design effectively separates multiple plastic flat wires, preventing them from sticking together during cooling. Furthermore, a metal plate is fixed to the side of the wire separating plate 83 facing the wire inlet 11, forming a water storage tank 84 between the wire separating plate 83 and the metal plate. When the plastic flat wires pass through the wire separating teeth on the wire separating plate 83, impurities and cooling water carried on the plastic flat wires are scraped into the water storage tank 84 for temporary storage, preventing impurities from falling into the cooling and cleaning tank body 2.

[0058] Optionally, two splitting plates 83 can be arranged at intervals along the length of the cooling and cleaning tank body 2, and a positioning roller is arranged between the two splitting plates 83. The two ends of the positioning roller are rotatably connected to the inner wall of the cooling and cleaning tank body 2, so that the quality of plastic flat yarn can be further increased through two splitting and combing processes.

[0059] The implementation principle of the plastic flat filament drawing cooling and cleaning tank system in this application embodiment is as follows: Before use, according to production needs, the first cylinder 32 and the second cylinder 41 are started to adjust the position of the cooling and cleaning tank body 2 along the drawing direction and vertical direction of the plastic flat filament. Then, the drive motor 212 is started to move all the guide rollers 5 up and down to the predetermined positions. Then, the two clamping plates 61 are placed on the positioning rod 72. When in use, the extruder is started to extrude the plastic flat filaments. The plastic flat filaments fall between the two clamping plates 61. Then, the two clamping plates 61 are slid to clamp each other and clamp all the plastic flat filaments between the two clamping plates 61. Then, the two clamping plates 61 are removed, and the clamping plates 61 are controlled to pass through the middle of all the guide rollers 5 and pass upward through the filament-separating teeth on the upper surface of the filament-separating plate 83, and then the plastic flat filaments are drawn out of the cooling and cleaning tank body 2. Finally, the drive motor 212 is started to drive each guide roller 5 to move up and down, thereby completing the drawing of the plastic flat filaments.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
