Description

Technical Field

[0001] This utility model belongs to the field of materials processing technology and relates to a device for removing impurities from nylon materials. Background Technology

[0002] Nylon materials are widely used in textiles, automobiles, electronics, and industrial manufacturing due to their excellent mechanical strength, wear resistance, and chemical resistance. In particular, the nylon materials used in the sealing rings of alkaline manganese batteries need to have better elasticity and toughness than ordinary nylon materials to ensure that the sealing ring maintains its sealing performance during assembly and use; they need to have sufficient strength and wear resistance to withstand the mechanical stress during battery use; and they need to maintain stable performance within the battery's operating temperature range and have good heat resistance to prevent deformation or softening at high temperatures. Therefore, special modifications are required for the nylon materials used in the sealing rings of alkaline manganese batteries.

[0003] When nylon is modified using twin-screw extrusion, many small molecular impurities remain during the die-drawing process, affecting the mechanical properties, thermal stability, crystallization behavior, and chemical stability of nylon. This reduces the injection molding stability of nylon materials and the leakage resistance of nylon seals.

[0004] In summary, although some existing technical solutions have solved the problem of removing small molecule impurities, there are still problems such as incomplete impurity removal and low cleaning efficiency, and there is still considerable room for improvement. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a device for removing impurities from nylon materials, comprising:

[0006] The base includes a chassis, a column, and an extension frame, wherein the column is vertically disposed on the chassis and the extension frame is connected to the column;

[0007] A high-temperature gas outlet assembly, which is mounted on the extension frame, includes a high-temperature heater, a compressed air inlet pipe for inputting compressed air, and a high-temperature gas outlet pipe for spraying high-temperature gas onto the surface of the nylon material. The compressed air enters the high-temperature heater through the compressed air inlet pipe, is heated, and then is ejected from the outlet end of the high-temperature gas outlet pipe.

[0008] In the above-mentioned nylon material impurity removal device, the high-temperature gas outlet component further includes a pressure regulating valve. The compressed air inlet pipe is connected to the high-temperature gas outlet pipe by passing through the pressure regulating valve and the high-temperature heater in sequence. The pressure regulating valve is used to regulate the gas pressure of the gas in the compressed air inlet pipe entering the high-temperature heater.

[0009] In the aforementioned nylon material impurity removal device, the extension frame is sleeved on the column, and the extension frame is vertically and vertically connected to the column.

[0010] The aforementioned nylon material impurity removal device also includes a lifting adjustment assembly, which includes a lifting wheel and a lifting hand crank. The lifting wheel is rotatably connected to the extension frame and is in frictional engagement with the outer surface of the column. The lifting hand crank is disposed on the extension frame and meshes with the lifting wheel to drive the lifting wheel to rotate, thereby causing the extension frame to move up and down along the column.

[0011] In the aforementioned nylon material impurity removal device, the column is further provided with a rough layer, and the lifting wheel contacts the column through the rough layer.

[0012] The aforementioned nylon material impurity removal device also includes a limiting member, which is connected to the column, and the extension frame can contact the limiting member during the lifting and lowering process.

[0013] In the aforementioned nylon material impurity removal device, the column is provided with limiting holes, and the number of limiting holes is at least two. The limiting member can be selectively disposed in the limiting holes.

[0014] In the aforementioned nylon material impurity removal device, the high-temperature air outlet pipe has a slit-shaped air outlet at its outlet end. The extension direction of the air outlet is consistent with the width direction of the nylon material, and its ejection plane is parallel to the surface of the nylon material.

[0015] The aforementioned nylon material impurity removal device also includes a power distribution box, which is disposed on the chassis and electrically connected to the high-temperature heater.

[0016] In the aforementioned nylon material impurity removal device, the base further includes a sliding wheel and a push-pull handle. The sliding wheel is connected to the bottom of the chassis, and the push-pull handle is connected to the top of the chassis.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This physical cleaning process significantly reduces the impurity content and micro-defect density on the surface of nylon products, thereby effectively improving the surface cleanliness and uniformity of the material, enhancing the density and chemical stability of the nylon material itself, reducing micropores or weak interfacial areas caused by the precipitation of small molecules, and thus greatly improving the injection molding stability of the product and its resistance to leakage in practical applications, especially under conditions of long-term immersion in liquid media or pressure differential.

[0019] 2. Appropriate air pressure can not only ensure that the airflow is heated evenly during the heating process and avoid local overheating or airflow turbulence, but also effectively prevent damage to the high-temperature heater due to excessive pressure. It can also avoid insufficient airflow speed due to excessively low pressure, which would affect heating efficiency and purging effect.

[0020] 3. By adjusting the height of the extension frame, the intensity and coverage of the high-temperature airflow jet can be precisely controlled, thereby adapting to the processing needs of nylon products of different specifications. For nylon strips with thicker cross sections and slower cooling, the extension frame can be appropriately lowered to shorten the distance between the nozzle and the material and enhance the thermal purging effect. For thin-walled or high-speed stretched materials, the extension frame can be raised to increase the spacing and avoid overheating and deformation. Attached Figure Description

[0029] The specific embodiments described herein are merely illustrative examples of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the scope of this utility model patent or exceeding the scope defined by the appended claims.

[0030] like Figure 1 As shown, a device for removing impurities from nylon materials includes: a base 1 and a high-temperature gas outlet component 2.

[0031] The base 1 includes a chassis 11, a column 12, and an extension frame 13. The column 12 is vertically arranged on the chassis 11, and the extension frame 13 is connected to the column 12.

[0032] The high-temperature gas outlet assembly 2 is mounted on the extension frame 13 and includes a high-temperature heater 21, a compressed air inlet pipe 22 for inputting compressed air, and a high-temperature gas outlet pipe 23 for spraying high-temperature gas onto the surface of the nylon material. The compressed air enters the high-temperature heater 21 through the compressed air inlet pipe 22 and is heated before being sprayed out from the outlet end of the high-temperature gas outlet pipe 23.

[0033] Specifically, after the nylon material is formed into strips, compressed air enters through the compressed air inlet pipe 22. The airflow first passes through the high-temperature heater 21 for rapid heating, reaching a temperature of over 350°C, thereby forming a stable high-temperature airflow. Subsequently, this fully heated air is transported through the high-temperature outlet pipe 23 and sprayed directionally from the nozzle at its end at a certain pressure and angle onto the surface of the nylon material that has just been injection molded and is still in a semi-molten or highly elastic state. This effectively promotes the pyrolysis and vaporization of small molecule nylon adhering to or remaining on the surface of the nylon material.

[0034] In this embodiment, this physical cleaning process significantly reduces the impurity content and micro-defect density on the surface of nylon products, thereby effectively improving the surface cleanliness and uniformity of the material, enhancing the density and chemical stability of the nylon material itself, reducing micropores or weak interfacial areas caused by the precipitation of small molecules, and thus greatly improving the injection molding stability of the product and its leakage resistance in practical applications, especially under conditions of long-term immersion in liquid media or pressure differential.

[0035] like Figure 1 As shown, based on the above embodiment, the high-temperature gas outlet assembly 2 further includes a pressure regulating valve 24. The compressed air inlet pipe 22 passes through the pressure regulating valve 24 and the high-temperature heater 21 in sequence to connect with the high-temperature gas outlet pipe 23. The pressure regulating valve 24 is used to regulate the gas pressure of the compressed air inlet pipe 22 entering the high-temperature heater 21.

[0036] Specifically, the operator can flexibly control the input pressure of compressed air entering the high-temperature heater 21 through the air pressure regulating valve 24 according to the processing requirements of different nylon materials, so as to ensure that the airflow is stable and meets the operating requirements of the heating equipment.

[0037] In this embodiment, a suitable air pressure can not only ensure that the airflow is heated evenly during the heating process and avoid local overheating or airflow turbulence, but also effectively prevent damage to the high-temperature heater 21 due to excessive pressure. It can also avoid insufficient airflow speed due to excessively low pressure, which would affect heating efficiency and purging effect.

[0038] like Figure 1 As shown, based on the above embodiment, the extension frame 13 is sleeved on the column 12, and the extension frame 13 and the column 12 are vertically connected.

[0039] Specifically, the extension frame 13 is installed on the column 12 of the main body of the equipment through a sleeve structure. It is connected to the column 12 by a sliding connection that can be raised and lowered, forming a vertically adjustable support and guide system. The extension frame 13 serves as the bearing platform for the high-temperature gas outlet pipe 23. The raising and lowering of its position directly determines the relative distance between the nozzle outlet of the high-temperature gas outlet pipe 23 and the surface of the nylon material being stretched and formed below.

[0040] In this embodiment, by adjusting the height of the extension frame 13, the intensity and coverage of the high-temperature airflow jet can be precisely controlled, thereby adapting to the processing requirements of nylon products of different specifications. For nylon strips with thicker cross sections and slower cooling, the extension frame 13 can be appropriately lowered to shorten the distance between the nozzle and the material and enhance the thermal blowing effect. For thin-walled or high-speed stretched materials, the extension frame 13 can be raised to increase the spacing and avoid deformation caused by overheating.

[0041] like Figure 1 As shown, based on the above embodiment, a lifting adjustment assembly 3 is also included. The lifting adjustment assembly 3 includes a lifting wheel 31 and a lifting hand crank 32. The lifting wheel 31 is rotatably connected to the extension frame 13, and the lifting wheel 31 is in frictional engagement with the outer surface of the column 12. The lifting hand crank 32 is disposed on the extension frame 13 and meshes with the lifting wheel 31 to drive the lifting wheel 31 to rotate, thereby driving the extension frame 13 to move up and down along the column 12.

[0042] Specifically, the lifting wheel 31 is rotatably mounted on the side wall of the extension frame 13 via bearings or a rotating shaft. Its wheel surface faces the column 12 and forms a frictional contact relationship with the outer surface of the column 12. The lifting hand crank 32 is fixedly installed on the outside of the extension frame 13 in a convenient operating position. Its output end is connected to the rotating shaft of the lifting wheel 31 through gear meshing to form a stable power transmission. When the operator turns the hand crank, the power is transmitted to the lifting wheel 31, driving it to rotate smoothly.

[0043] In this embodiment, the lifting adjustment component 3 is driven manually, which has the advantages of simple structure, stable operation and convenient maintenance. The operator can accurately control the lifting range of the extension frame 13 according to the on-site process requirements, so as to achieve fine adjustment of the optimal distance between the nozzle of the high temperature exhaust pipe 23 and the surface of the nylon material.

[0044] like Figure 1 As shown, based on the above embodiment, the column 12 is also provided with a rough layer 121, and the lifting wheel 31 contacts the column 12 through the rough layer 121.

[0045] In this embodiment, the rough layer 121 can be formed by various processes, such as sandblasting, knurling, laser etching, electrochemical etching, or surface spraying with a high friction coefficient material, which significantly increases the actual contact area and surface friction coefficient between the column 12 and the lifting wheel 31. Compared with a smooth metal surface, this treated rough layer 121 can effectively prevent the lifting wheel 31 from slipping or spinning during transmission, and can maintain stable transmission performance.

[0046] like Figure 1 As shown, based on the above embodiment, a limiting member 4 is also included. The limiting member 4 is connected to the column 12, and the extension frame 13 can contact the limiting member 4 during the lifting and lowering process.

[0047] In this embodiment, the limiting members 4 are installed at a specific height position on the column 12 to physically constrain the movement range of the extension frame 13, effectively avoiding structural interference or component damage caused by excessive lifting and lowering, and ensuring the safety of equipment operation.

[0048] like Figure 1 As shown, based on the above embodiment, the column 12 is provided with limiting holes 122, and the number of limiting holes 122 is at least two. The limiting member 4 can be selectively provided in the limiting holes 122.

[0049] Specifically, there are at least two limiting holes 122, which are distributed in a linear array on the column 12. These limiting holes 122 serve as adjustable installation reference points, providing multiple selectable fixed positions for the position setting of the limiting member 4.

[0050] In this embodiment, the limiting member 4 can be detachably installed in one or more limiting holes 122 through threaded connection, pin insertion, or snap-fit ​​structure, so as to realize free selection and dynamic adjustment of position. The operator does not need to replace other hardware. He only needs to screw the limiting member 4 into or insert it into the limiting hole 122 of the corresponding height to quickly reconstruct the safe travel range of the lifting system.

[0051] like Figure 1 As shown, based on the above embodiment, the high-temperature air outlet pipe 23 has a slit-shaped air outlet (not shown in the figure) at its outlet end. The extension direction of the air outlet is consistent with the width direction of the nylon material, and its ejection plane is parallel to the surface of the nylon material.

[0052] In this embodiment, the ejection plane of the air outlet is parallel to the surface of the nylon material, which can uniformly blow on the surface of the nylon material and efficiently vaporize the small molecules on the surface of the nylon material, effectively avoiding local undertreatment or overheating caused by uneven airflow.

[0053] like Figure 1 As shown, based on the above embodiment, a power distribution box 5 is also included. The power distribution box 5 is disposed on the chassis 11 and is electrically connected to the high-temperature heater 21.

[0054] In this embodiment, the power distribution box 5 is fixedly installed on the chassis 11. The power distribution box 5 is reliably connected to the high-temperature heater 21 through a cable. The core function of the power distribution box 5 is to adjust the working temperature of the high-temperature heater 21 and control its heating process to ensure that the output compressed air can be stably maintained within the set temperature range required by the process.

[0055] like Figure 1As shown, based on the above embodiment, the base 1 further includes a sliding wheel 14 and a push-pull handle 15. The sliding wheel 14 is connected to the bottom of the chassis 11, and the push-pull handle 15 is connected to the top of the chassis 11.

[0056] Specifically, the sliding wheels 14 are installed around the bottom of the chassis 11 to ensure the stability and load-bearing capacity of the equipment during movement, and the push-pull handle 15 is fixedly connected to one end of the top of the chassis 11 so that the operator can push or pull the equipment through the push-pull handle 15.

[0057] In this embodiment, the design of the sliding wheel 14 and the push-pull handle 15 makes the whole device no longer limited to a single workstation, but can be easily transferred from one nylon production line to another, greatly improving the utilization rate and flexibility of the impurity removal equipment.
