Description

Technical Field

[0001] This application relates to the field of non-woven textiles, and in particular to a fiber stripping device. Background Art

[0002] Non-woven technology is an important part of textile technology. Compared with traditional textiles, it has the advantages of high output and low cost. Non-woven processes are classified according to the fiber length of the final product and are divided into filament fibers and staple fibers. Whether it is staple fiber or filament, a consolidation process such as needling, hydroentangling, hot air or hot rolling is required in the production process.

[0003] With the upgrading of China's non-woven technology, especially the spunbond-meltblown non-woven technology is developing rapidly in the direction of high speed and low gram weight. New difficulties have emerged in this process: ① Before consolidation, the fibers adhere to the wire mesh curtain and move at high speed together with the wire mesh curtain. During this process, relative displacement occurs with the originally static air flow in the environment. The higher the production speed, the greater the friction and resistance of the fibers to the environmental air flow, and the greater the external air flow interference that needs to be resisted, and the more serious the phenomenon of fiber fibrillation inside; ② The fundamental reason why the fibers can move together with the wire mesh curtain is that the surface of the wire mesh curtain is rough, and part of the fibers will be embedded in the gaps of the wire mesh curtain, so the wire mesh curtain has a certain adhesion ability to the fibers. As the gram weight of the produced product becomes smaller and the fibers become thinner, among the three forces of gravity, electrostatic force and adhesion force between the fibers and the wire mesh curtain, the influence factor of gravity decreases the fastest, thus increasing the influence of the other two forces. When it is necessary to strip the fibers from the wire mesh curtain surface, the influence of the adhesion force between the wire mesh curtain and the fibers will be obvious, resulting in an increase in the difficulty of stripping. The patented technology is to solve the problem of fiber stripping when producing low-gram weight products. Summary of the Invention

[0004] In order to solve the problem of fiber stripping when producing low-gram weight products, this application provides a fiber stripping device.

[0005] A fiber stripping device provided by this application adopts the following technical solution: A fiber stripping device includes a first fabric wire mesh curtain, a second fabric wire mesh curtain, a bottom suction mechanism and a blowing mechanism; The first fabric wire mesh curtain is used to receive the prepared virgin fibers, lay them on the surface of the wire mesh curtain to form a virgin fiber layer, and convey the fluffy virgin fiber layer to the second fabric wire mesh curtain; The second fabric wire mesh curtain is located below the first fabric wire mesh curtain and is used to receive the prepared virgin fibers and the virgin fiber layer stripped and conveyed by the first fabric wire mesh curtain, and convey them to the next process; The bottom suction mechanism is located below the part of the second fabric wire mesh curtain close to the first fabric wire mesh curtain and is used to suck air flow to adsorb the virgin fiber layer stripped from the first fabric wire mesh curtain; The blowing mechanism is located above the part of the first fabric mesh curtain close to the second fabric mesh curtain, and is used to blow air flow to assist in peeling the primary fiber layer from the first fabric mesh curtain.

[0006] By adopting the above technical solution, the first fabric mesh curtain receives the primary fibers and forms a primary fiber layer to be conveyed towards the second fabric mesh curtain, and the second fabric mesh curtain synchronously receives the primary fibers to form a primary fiber layer and conveys it towards the consolidation mechanism. When the primary fiber layer transmitted on the first fabric mesh curtain reaches the first relay transmission section, the air blown by the blowing mechanism peels the primary fiber layer from the first fabric mesh curtain, and under the action of the suction mechanism, the primary fiber layer is laminated on the primary fiber layer of the second fabric mesh curtain and conveyed to the consolidation mechanism together, solving the problem of fiber peeling when producing low-gram-weight products.

[0007] Preferably, the first fabric mesh curtain includes a horizontal receiving section, a first relay transmission section for relaying and transmitting to the second fabric mesh curtain, and a return section parallel to the receiving section. The part of the second fabric mesh curtain close to the first fabric mesh curtain and located below the first relay transmission section is named the second relay transmission section. An included angle of 10-15 degrees is formed between the first relay transmission section and the second relay transmission section; the blowing mechanism is located at the first relay transmission section, and the suction mechanism is located at the second relay transmission section.

[0008] By adopting the above technical solution, the first relay transmission section and the second relay transmission section are close to each other at a small included angle, and the blowing mechanism and the suction mechanism cooperate at the close positions to peel the primary fiber layer on the first relay transmission section and adsorb it on the second relay transmission section.

[0009] Preferably, the bottom suction mechanism includes a fan, a suction pipe connected to the air inlet of the fan, and a suction box connected to the suction pipe and located below the second relay transmission section. The length of the suction box is equal to the width of the second fabric mesh curtain, and the length direction of the suction box is arranged along the width direction of the second fabric mesh curtain. The entire upper surface of the suction box is opened to form a suction air inlet and is attached to the lower surface of the second relay transmission section.

[0010] By adopting the above technical solution, by setting the length of the suction box to be equal to the width of the second fabric mesh curtain, the suction air flow can exert a relatively uniform force on the primary fiber layer, and there will be no position deviation or force pulling due to uneven force.

[0011] Preferably, a suction air outlet is provided at a position near the bottom of one side of the suction box. The side wall of the suction box on the side away from the suction air outlet includes a vertical section of the suction side wall and a curved transition section of the suction side wall located below the vertical section of the suction side wall. Inside the suction box, n suction partition plates are evenly distributed at equal intervals along the length direction of the suction box. The width of each suction partition plate is equal to the width inside the suction box. Each suction partition plate includes a vertical section of the suction partition and a curved transition section of the suction partition. The distance between the lower end of the curved transition section of the suction partition and the bottom plate of the suction box is distributed in an arithmetic progression, and the distance between the lower end of the curved transition section of the suction partition adjacent to the suction air outlet and the bottom plate of the suction box is n / (n + 1) times the diameter of the suction air outlet.

[0012] By adopting the above technical solution, the inside of the suction box is divided into several areas by the suction partition plates, and the air is sucked more evenly in these areas, alleviating the problem of large suction differences at different positions of the suction air inlet caused by unequal distances from the suction air outlet.

[0013] Preferably, the lengths of the vertical sections of the suction partitions are all equal. The curved transition sections of the suction partitions are all tangent to the vertical sections of the suction partitions and the other ends are tangent to the parallel plane of the bottom plate of the suction box. The radius of the curved transition section of the suction partition closer to the suction air outlet is smaller.

[0014] By adopting the above technical solution, the surface of the suction partition plate is a smooth transition structure, reducing the resistance to the air flow.

[0015] Preferably, the blowing mechanism includes a blowing pipe communicated with the air outlet of the fan and a blowing box communicated with the blowing pipe. The length of the blowing box is equal to the width of the first fabric mesh curtain, and the length direction of the blowing box is arranged along the width direction of the first fabric mesh curtain. The entire lower surface of the blowing box is opened to form a blowing air outlet and is attached to the upper surface of the first transfer section opposite to the center of the suction box. The width of the water spraying air outlet is less than half of the width of the suction air inlet.

[0016] By adopting the above technical solution, by setting the length of the blowing box to be equal to the width of the first fabric mesh curtain, the blowing air flow can act on the primary fiber layer more evenly, and there will be no position deviation or force pulling due to uneven force.

[0017] Preferably, a blowing air inlet is provided at a position near the top of one side of the blowing box. The side wall of the blowing box on the side away from the blowing air inlet includes a vertical section of the blowing side wall and an arc-shaped transition section of the blowing side wall located above the vertical section of the blowing side wall. Inside the blowing box, n blowing partition plates are evenly distributed at equal intervals along the length direction of the blowing box. The width of the blowing partition plate is equal to the width inside the blowing box. Each blowing partition plate includes a vertical section of the blowing partition and an arc-shaped transition section of the blowing partition. The spacing between the upper end of the arc-shaped transition section of the blowing partition and the top plate of the blowing box is distributed in an arithmetic progression, and the spacing between the lower end of the arc-shaped transition section of the blowing partition adjacent to the blowing air outlet and the top plate of the blowing box is n / (n + 1) times the diameter of the blowing air outlet.

[0018] By adopting the above technical solution, the inside of the suction box is divided into several areas by the blowing partition plates, and the air flow is blown in a relatively balanced manner in these areas, alleviating the problem of a large difference in the air flow rate blown out at each position of the blowing air outlet due to unequal distances from the blowing air inlet.

[0019] Preferably, the lengths of the vertical sections of the blowing partitions are all equal. The arc-shaped transition sections of the blowing partitions are all tangent to the vertical sections of the blowing partitions and the other ends are tangent to the parallel plane of the top plate of the blowing box. The radius of the arc-shaped transition section of the blowing partition closer to the blowing air outlet is smaller.

[0020] By adopting the above technical solution, the surface of the blowing partition plate is a smoothly transitional structure, reducing the resistance to the air flow.

[0021] Preferably, a dust collection pipe is connected to the suction air outlet. A vertically extending pipe is connected to the lower part of the end of the dust collection pipe away from the suction box. A dust collection box is detachably connected to the lower end of the outer side of the vertically extending pipe. An inclined upwardly extending suction pipe is communicated with the upper side of the end of the dust collection pipe away from the suction box. A filter piece is provided at the connection between the suction pipe and the dust collection pipe. A filter net is formed in the center of the filter piece.

[0022] By adopting the above technical solution, before the equipment runs, the first power source, the second power source and the fan are started first, so that the suction air flow formed by the fan cleans the dust on the fabric mesh curtain and concentrates it in the dust collection box for regular cleaning to achieve a cleaning effect, and there is no need to separately set a brush structure.

[0023] Preferably, a circular installation groove is formed on the inner side wall of the connection end of the suction pipe and the dust collection pipe. The lower half of the installation groove penetrates through the suction pipe. A sealing rubber layer is coated on the outer side of the filter piece. A downwardly extending abutting piece is formed on the part of the filter piece passing through the suction pipe through the penetrating position of the installation groove. The side surface of the abutting piece fits the outer side surface of the vertically extending pipe, and the lower end surface of the abutting piece abuts against the upper end surface of the dust collection box.

[0024] By adopting the above technical solution, the dust box and the abutment sheet abut against each other so that the sealing rubber layer of the filter sheet abuts against the inner wall of the installation groove to form a sealing surface, and the sealing effect is better. At the same time, when cleaning the filter sheet, the dust box must be removed before the filter sheet is removed, and the two are cleaned together to avoid the situation where the filter is removed alone and then forgotten to be reinstalled after cleaning, resulting in the dust in the dust box being sucked out.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The first fabric mesh receives the primary fibers and forms a primary fiber layer, which is then transported to the second fabric mesh. The second fabric mesh simultaneously receives the primary fibers and forms a primary fiber layer, which is then transported to the consolidation mechanism. When the primary fiber layer on the first fabric mesh reaches the first adoptive transmission section, the wind blown by the blowing mechanism peels the primary fiber layer off the first fabric mesh, and the primary fiber layer is superimposed on the primary fiber layer of the second fabric mesh under the action of the suction mechanism, and they are transported to the consolidation mechanism together, thus solving the fiber peeling problem when producing low-weight products.

[0026] 2. The interior of the suction box is divided into several areas by a suction partition plate, and air is extracted from several areas in a relatively even manner, thereby alleviating the problem of large differences in suction force at various positions of the suction inlet caused by unequal distances from the suction outlet.

[0037] Specific usage process: The first fabric mesh curtain 1 receives the primary fibers and forms a primary fiber layer and conveys it towards the second fabric mesh curtain 2. The second fabric mesh curtain 2 synchronously receives the primary fibers to form a primary fiber layer and conveys it towards the consolidation mechanism 36. When the primary fiber layer transmitted on the first fabric mesh curtain 1 reaches the first relay transmission section 7, the air blown by the blowing mechanism 4 strips the primary fiber layer from the first fabric mesh curtain 1, and under the action of the suction mechanism, the primary fiber layer is laminated on the primary fiber layer of the second fabric mesh curtain 2 and is conveyed to the consolidation mechanism 36 together. The problem of fiber stripping during the production of low-gram products is solved.

[0038] Embodiment Two: ​The difference between this embodiment and the first embodiment is only that a dust collecting pipe 29 is connected to the suction air outlet 14. A vertically extending pipe 30 is communicated below one end of the dust collecting pipe 29 away from the suction box 12. An external thread is formed at the lower end of the outer side surface of the vertically extending pipe 30, and a dust collecting box 31 is threadedly connected thereto. An upwardly inclined suction pipe 11 is communicated above one end of the dust collecting pipe 29 away from the suction box 12.

A filter sheet 33 is detachably installed in the installation groove 32. A filter net is formed at the center of the filter sheet 33, and a sealing rubber layer is coated on the outer side of the filter sheet 33. A butting piece 35 extending downward is formed at the part of the filter sheet 33 passing through the suction pipe 11 through the penetrating position of the installation groove 32. The side surface of the butting piece 35 fits the outer side surface of the vertically extending pipe 30, and the lower end surface of the butting piece 35 abuts against the upper end surface of the dust collecting box 31.

[0039] In the spunbond process, the primary fabric layer is formed by randomly laying a web of filaments extruded from a high-temperature molten polymer material through a spinneret. If there are dust or impurities in the environment, they may adhere to the surface of the uncured fibers, resulting in a decrease in the uniformity of the fiber web, impaired mechanical properties, and even defects such as holes. Therefore, it is necessary to configure a brush roller on the fabric mesh curtain to regularly remove residual particles, and cooperate with the negative pressure suction in the equipment room to achieve the effect of removing dust and impurities. And in this embodiment, the first power source, the second power source and the fan can be started before the equipment runs, so that the suction air flow formed by the fan can clean the dust on the fabric mesh curtain and concentrate it in the dust collecting box 31 for regular cleaning to achieve the cleaning effect, and there is no need to separately set a brush structure.

[0040] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
