Description

Technical Field

[0001] This utility model relates to the technical field of lint adsorption devices, and more specifically, to a lint adsorption device for the production of pile knitted fabrics. Background Technology

[0002] In the production process of napped knitted fabric, the nap adsorption process directly affects the finished product quality and production efficiency. During the production process, the friction between the fabric and the equipment parts easily generates static electricity, which leads to the adhesion of dust and broken nap. Therefore, it is necessary to remove static electricity from the fabric surface through an static elimination device.

[0003] Existing static electricity elimination devices in fabric production mostly employ structures such as ionizing air bars and static elimination brushes. Ionizing air bars generate positive and negative ions to neutralize static electricity by ionizing air, but they have limitations in their effective range and the ion concentration is easily affected by ambient temperature and humidity, resulting in reduced static electricity elimination efficiency in humid environments. Static elimination brushes rely on the contact between conductive fibers and the fabric to dissipate static electricity; however, after long-term use, the conductive fibers wear out severely, not only weakening the static electricity elimination effect but also potentially scratching the fabric surface. Therefore, we propose a lint adsorption device for the production of pile knitted fabrics. Utility Model Content

[0004] This invention proposes a lint adsorption device for the production of napped knitted fabrics. The electrostatic elimination brush used in the traditional napped knitted fabric production process has conductive fibers that wear down and may scratch the fabric after long-term use. The metal conductive plate of this device does not come into direct contact with the fabric, so there is no risk of wear and scratching of the fabric.

[0005] The present invention proposes a lint adsorption device for producing pile knitted fabric, comprising a mounting frame, multiple heat sinks, two cooling fans, two metal conductive plates, and two sets of guide components.

[0006] The mounting frame has a fabric channel inside;

[0007] Two sets of guide components are symmetrically arranged at the inlet and outlet ends of the fabric channel. Each set of guide components includes guide rollers symmetrically arranged vertically. The two ends of the guide rollers are rotatably connected to the side wall of the mounting frame through bearings.

[0008] Two metal conductive plates are respectively disposed at the top and bottom of the fabric channel. The sidewalls of the metal conductive plates are fixedly connected to the inner sidewall of the mounting frame through connectors. The metal conductive plates discharge the charge through a grounding wire.

[0009] Multiple heat sinks are arranged in an array on the surface of the metal conductive plate on the side opposite to the fabric.

[0010] Two cooling fans are respectively installed on the side of the heat sink of the two metal conductive plates. The cooling fans are fixedly connected to the mounting bracket by a bracket, and the air outlet of the cooling fans faces the heat sink array.

[0011] Preferably, the inner wall of the mounting frame has two suction pipes fixedly connected in an upper and lower structure, and the cloth passes through the space between the two suction pipes.

[0012] Preferably, an exhaust fan is fixedly connected to the outer wall of the mounting frame, a connecting pipe is fixedly connected to the air inlet of the exhaust fan, a U-shaped pipe is fixedly connected to the end of the connecting pipe, and the two ends of the U-shaped pipe are respectively fixedly connected to the corresponding dust suction pipes.

[0013] Preferably, two support plates are fixedly connected to the inner wall of the mounting frame, a filter cylinder is fixedly connected to the top of the support plates, and the end of the filter cylinder is fixedly connected to the exhaust port of the exhaust fan.

[0014] Preferably, the inner end of the filter cartridge protrudes inward to form a convex ring, and the outer wall of the convex ring is provided with multiple air inlet holes.

[0015] Preferably, the inner wall of the filter cylinder is fitted with a collection cylinder, the convex ring passes through the end hole of the collection cylinder and is slidably connected to it, at least two slide rods are fixedly connected to the inner end wall of the collection cylinder, each slide rod is fitted with a spring on its outer wall, each slide rod end is fixedly connected with a limit sleeve, a sealing disc is fitted to the inner wall of the collection cylinder, the sealing disc abuts against the end of the convex ring, and a slider with the same number as the slide rods is fixedly connected to the outer wall of the sealing disc, the end of the slide rod passes through the slider and is slidably connected to it.

[0016] Preferably, one end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the limiting sleeve.

[0017] Preferably, a rubber sleeve is fixedly connected to the outer wall of the collecting cylinder, and the rubber sleeve is in frictional contact with the inside of the filter cylinder.

[0019] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0020] By using a grounded metal conductive plate to discharge static electricity, the problem of existing static electricity elimination devices is solved. The ion air bar used in the traditional napped knitted fabric production process is affected by the ambient temperature and humidity, and the static electricity elimination efficiency decreases in humid environments. However, the metal conductive plate of this device relies on the principle of physical conductivity and is not affected by environmental factors, so it can stably eliminate static electricity. The static electricity elimination brush used in the traditional napped knitted fabric production process will wear down and may scratch the fabric after long-term use. The metal conductive plate of this device does not come into direct contact with the fabric, so there is no risk of wear and scratching the fabric. Attached Figure Description

[0030] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model. In this utility model, unless otherwise expressly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figure 1 and Figure 7 As shown, a lint adsorption device for producing pile knitted fabric includes a mounting frame 1, multiple heat sinks 301, two cooling fans 20, two metal conductive plates 3, and two sets of guide components.

[0032] The mounting frame 1 has a fabric channel inside;

[0033] Two sets of guide components are symmetrically arranged at the inlet and outlet ends of the fabric channel. Each set of guide components includes guide rollers 2 arranged symmetrically at the top and bottom. The two ends of the guide rollers 2 are rotatably connected to the side wall of the mounting frame 1 through bearings. The guide rollers 2 at the inlet and outlet ends of the fabric channel play a role in guiding and tensioning the fabric to ensure smooth fabric conveying.

[0034] Two metal conductive plates 3 are respectively set at the top and bottom of the fabric channel. The sidewalls of the metal conductive plates 3 are fixedly connected to the inner sidewall of the mounting frame 1 through connectors. The metal conductive plates 3 discharge the charge through grounding wire.

[0035] Multiple heat sinks 301 are arranged in an array on the surface of the metal conductive plate 3 on the side opposite to the fabric; the heat sinks 301 increase the heat dissipation area of ​​the metal conductive plate 3.

[0036] Two cooling fans 20 are respectively positioned on the side of the heat sink 301 of the two metal conductive plates 3. The cooling fans 20 are fixedly connected to the mounting bracket 1 through the bracket, and the air outlet of the cooling fans 20 is facing the heat sink 301 array.

[0037] The metal conductive plate 3 conducts static electricity from the fabric through a grounding wire. Compared with the ion fan bar, it is not affected by the ambient temperature and humidity and can stably eliminate static electricity. Compared with the static elimination brush, it will not wear out or scratch the fabric surface. The combination of heat sink 301 and cooling fan 20 dissipates the heat generated by the metal conductive plate 3 in a timely manner, preventing the conductivity and service life of the metal conductive plate 3 from being affected by excessive temperature, and ensuring the stability and continuity of static elimination.

[0038] In this embodiment, as Figure 1 As shown, the inner wall of the mounting bracket 1 has two suction pipes 4 fixedly connected in an upper and lower structure, and the cloth passes through the space between the two suction pipes 4.

[0039] Two suction tubes 4 are located on the upper and lower sides of the fabric, respectively, which can adsorb lint that falls off the fabric surface from different directions. Compared with a single suction tube 4, the adsorption range is expanded and the lint adsorption efficiency is improved.

[0040] In this embodiment, as Figure 8 As shown, an exhaust fan 21 is fixedly connected to the outer wall of the mounting bracket 1. A connecting pipe 22 is fixedly connected to the air inlet of the exhaust fan 21. A U-shaped pipe 23 is fixedly connected to the end of the connecting pipe 22. Both ends of the U-shaped pipe 23 are fixedly connected to the corresponding dust suction pipes 4.

[0041] The exhaust fan 21 provides suction, which creates negative pressure in the suction pipe 4 to draw in the lint from the fabric surface. The connecting pipe 22 and the U-shaped pipe 23 ensure stable airflow.

[0042] In this embodiment, as Figure 1 As shown, two support plates 5 are fixedly connected to the inner wall of the mounting bracket 1, and a filter cylinder 6 is fixedly connected to the top of the support plate 5. The end of the filter cylinder 6 is fixedly connected to the exhaust port of the exhaust fan 21.

[0043] The filter cartridge 6 is connected to the exhaust port of the exhaust fan 21 to filter the air containing lint, prevent the lint from being discharged into the atmosphere and avoid environmental pollution, and at the same time realize the centralized collection of lint for easy subsequent processing.

[0044] In this embodiment, as Figure 4 As shown, the inner end of the filter cylinder 6 protrudes inward to form a convex ring 7, and the outer wall of the convex ring 7 is provided with multiple air inlet holes 8.

[0045] The air inlet holes 8 are evenly distributed on the outer wall of the convex ring 7, so that air enters the collection cylinder 14 evenly.

[0046] In this embodiment, as Figure 3 and Figure 5 As shown, a collection cylinder 14 is fitted inside the filter cylinder 6. A convex ring 7 passes through the end hole of the collection cylinder 14 and is slidably connected to it. At least two slide rods 11 are fixedly connected to the inner end wall of the collection cylinder 14. A spring 13 is fitted on the outer wall of each slide rod 11. A limit sleeve 12 is fixedly connected to the end of each slide rod 11. A sealing disc 9 is fitted inside the collection cylinder 14. The sealing disc 9 abuts against the end of the convex ring 7. A slider 10 with the same number as the slide rods 11 is fixedly connected to the outer wall of the sealing disc 9. The end of the slide rod 11 passes through the slider 10 and is slidably connected to it. One end of the spring 13 is fixedly connected to the slider 10, and the other end of the spring 13 is fixedly connected to the limit sleeve 12.

[0047] The sealing disc 9 and the convex ring 7 cooperate to ensure the sealing of the filter cartridge 6 and prevent unfiltered air from leaking out. When cleaning the lint, simply pull the handle 19 to pull out the collection cartridge 14. The outer wall of the collection cartridge 14 is fixedly connected to a rubber sleeve 15, which makes frictional contact with the inside of the filter cartridge 6.

[0048] The external threaded ring 16 is threadedly connected to the collection cylinder 14, which facilitates the disassembly of the annular mesh 17 and the fixing plate 18, and makes it easy to clean the lint inside the collection cylinder 14.

[0049] In this embodiment, as Figure 6 As shown, the inner wall of the collecting cylinder 14 is threaded with an external threaded ring 16, the inner wall of the external threaded ring 16 is fixedly connected with an annular mesh 17, the inner wall of the annular mesh 17 is fixedly connected with a fixed disc 18, and the end face of the fixed disc 18 is fixedly connected with a handle 19.

[0050] When a static-charged napped knitted fabric enters the fabric channel of the mounting frame 1 and approaches the metal conductive plate 3, according to the principle of electrostatic induction, the static charge on the fabric will cause the free electrons on the surface of the metal conductive plate 3 to redistribute. If the fabric is positively charged, the side of the metal conductive plate 3 closest to the fabric will accumulate electrons and become negatively charged, while the other side will be positively charged; if the fabric is negatively charged, the side of the metal conductive plate 3 closest to the fabric will become positively charged due to the repulsion of electrons, while the other side will be negatively charged.

[0051] The metal conductive plate 3 is connected to the ground via a grounding wire, which can be considered an infinitely large charge reservoir. Under electrostatic induction, the charge induced on the metal conductive plate 3, opposite to the static electricity on the fabric, attracts the static electricity on the fabric, causing the static charge on the fabric to gradually move towards the metal conductive plate 3. Simultaneously, excess charge induced on the metal conductive plate 3 is conducted to the ground through the grounding wire, ensuring that the metal conductive plate 3 remains electrically neutral. As this process continues, the static electricity on the fabric is continuously neutralized, ultimately achieving static elimination.

[0052] Working principle: During the production process, the pile knitted fabric enters the fabric channel of the mounting frame 1. The guide roller 2 guides the fabric to be transported smoothly. When the fabric passes through the fabric channel, the static electricity on the surface of the fabric will be conducted to the metal conductive plates 3 at the top and bottom. The metal conductive plates 3 discharge the charge through the grounding wire, thereby realizing the elimination of static electricity.

[0053] When the metal conductive plate 3 rubs against the fabric, it generates a certain amount of heat. The air blown out by the cooling fan 20 is directed towards the heat sink 301, which accelerates the airflow and quickly removes the heat generated by the metal conductive plate 3, ensuring that the metal conductive plate 3 works stably.

[0054] During the static electricity elimination process, the exhaust fan 21 is started, and the suction pipe 4 generates suction through the connecting pipe 22 and the U-shaped pipe 23 to adsorb the lint that falls off the fabric surface. The air with lint is sucked into the suction pipe 4 and then enters the filter cylinder 6 through the exhaust fan 21. The air enters the collection cylinder 14 through the air inlet 8 on the convex ring 7. The filtered air is discharged from the annular mesh 17, and the lint is intercepted in the collection cylinder 14.

[0055] When cleaning the lint inside the collection cylinder 14, pull the handle 19 to move the rubber sleeve 15 at the end of the collection cylinder 14 out of the filter cylinder 6. Under the elastic force of the spring 13, the sealing disc 9 slides into the end hole of the collection cylinder 14 to seal the end of the collection cylinder 14. The collection cylinder 14 is then pulled out of the filter cylinder 6. After cleaning, push the collection cylinder 14 back to its original position. At this time, the convex ring 7 squeezes the sealing disc 9 and squeezes it out of the end hole of the filter cylinder 6 to complete the installation.

[0056] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
