Description

Technical Field

[0001] The present invention relates to the technical field of fiber web manufacturing, and in particular to a fiber web manufacturing device and method. Background Art

[0002] Mesh fiber products are needed in application scenarios such as medical dressings, window screens, air conditioning filters, food filter cloths, mosquito nets, etc. The traditional manufacturing process is: first make fibers, and then weave them into mesh fiber products through warp knitting. This process can perform deep processing on the fibers before warp knitting, so that the fibers and the mesh fiber nets made by the warp knitting process have properties such as elasticity and flexibility.

[0003] However, during the implementation of the above process: since the fiber preparation process and the fiber warp knitting process are not connected, a variety of equipment and processes need to be replaced during the manufacturing process, the process is complicated, the efficiency is low, and the cost is high.

[0004] However, in some application scenarios, such as fiber meshes for house decoration, air conditioning filters, window screens, etc., the technical indicators such as elasticity and flexibility of fiber mesh products are relatively low. Using the above-mentioned traditional process to make these products is not conducive to saving processes, and thus is not conducive to improving the production efficiency of fiber meshes. Summary of the invention

[0005] The present invention provides a fiber web manufacturing device and method, which can solve at least one of the above technical problems.

[0006] To solve the above technical problems, one or more embodiments of the present invention provide a fiber web manufacturing device having a first direction and a second direction that are approximately horizontal and intersecting, the first direction being the discharge direction of the manufacturing device, and including a melting device, a pattern nozzle, a workbench, a pulling device, and a winding device.

[0007] The melting device can melt the raw material into a fluid material and output it. The row-type nozzle has an inner cavity and at least one row of nozzle holes connected to the inner cavity. The inner cavity is connected to the melting device and can accommodate the fluid material output by the melting device. The nozzle holes can spray the fluid material downward in the form of fiber filaments. The nozzle holes are located at the lower end of the row-type nozzle, and the nozzle holes are arranged in sequence along the first direction. The row-type nozzle can reciprocate and translate along the second direction.

[0008] The workbench is located below the row-type nozzle to receive the fiber filaments discharged from the nozzle hole. The workbench is a rotatable rotating roller, and the central axis of the rotating roller is horizontal and perpendicular to the first direction. Alternatively, the workbench is a belt conveyor line whose surface can move along the first direction. The workbench can rotate or move synchronously when the row-type nozzle reciprocates and translates along the second direction, so that the fiber filaments dropped on the workbench form dropped filaments arranged at an angle to the first direction, and the dropped filaments are interwoven and shaped into a fiber web.

[0009] The pulling device is used to pull the fiber web shaped at the working table along a first direction, and the winding device is used to store the fiber web in a cylindrical or stacked manner.

[0010] One or more embodiments of the present invention further provide a method for manufacturing a fiber web, comprising the following steps:

[0011] The raw materials are put into a molten fluid state by using a melting device, so that the fluid material is sprayed downward from the discharge nozzle.

[0012] The row-shaped nozzle reciprocates along the second direction, and the working table moves so that its upper end reciprocates along the first direction. The unidirectional movement of the row-shaped nozzle along the second direction forms parallel and non-overlapping drop wires on the working table, and the reciprocating movement of the row-shaped nozzle along the second direction forms mutually intersecting drop wires on the working table to shape the fiber web.

[0013] The workbench is heated, and the residual heat of the fiber filaments is used to fuse the intersections of the fiber web together.

[0014] The fiber web is separated from the working table and pulled in the discharge direction of the manufacturing device, and a pulling temperature lower than the working table temperature is provided to the fiber web during the pulling process. The fiber web pulled out of the working table is pulled in at least one direction so that the dropped fibers constituting the fiber web are pulled in a balanced manner.

[0015] The stretched fiber web is shaped, and the shaped fiber web is wound into a roll, or reciprocally folded into a stack for storage.

[0016] The beneficial effects of one or more of the above technical solutions are:

[0017] The melting equipment of this scheme melts the raw material into a fluid raw material, and the row nozzle uses the nozzle hole to spray the fluid raw material downward in the form of fiber filaments. A workbench is arranged under the row nozzle, and the workbench can rotate or move synchronously when the row nozzle reciprocates and translates along the second direction, so that the fallen fiber filaments are interwoven and formed into a fiber web.

[0018] This arrangement allows the process of fiber filament molding and fiber mesh interweaving and shaping into a fiber mesh to be integrated into one manufacturing device, without the need to replace multiple equipment and processes. The manufacturing process is simple and convenient, and its manufacturing efficiency is improved.

[0019] In addition, in this solution, the dropped wires dropped onto the workbench are arranged at an angle to the first direction, and the dropped wires formed by the reciprocating motion of the row nozzles along the second direction intersect with each other to form diamond-shaped wire holes. When the pulling device is pulled along the first direction, the pulling force is parallel to a diagonal direction of the fiber web, so the dropped wires in the two intersecting directions that constitute the fiber web obtain the same draft ratio. The dropped wires that have been stretched and shaped have sufficient toughness and strength and can be directly put into use as finished products. That is, this solution simplifies the manufacturing process of traditional fiber mesh products without deep processing of the fiber filaments, greatly reduces the manufacturing of finished products, and greatly improves manufacturing efficiency.

DETAILED DESCRIPTION

[0026] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0027] See also Figure 1This embodiment provides a manufacturing device for a fiber web 3, which has a substantially horizontal and intersecting first direction (i.e., direction B1 shown in the figure) and a second direction, the first direction being the discharge direction of the manufacturing device, and includes a melting device (not shown in the figure), a row nozzle 6, a workbench, a pulling device, and a winding device 10. This embodiment also includes a linkage control system, which is used to control the automatic operation of the above-mentioned parts.

[0028] The row-type nozzle 6 has an inner cavity and at least one row of nozzles connected to the inner cavity. The inner cavity is connected to the melting device, and the inner cavity can accommodate the fluid material output by the melting device. The nozzles can spray the fluid material downward in the form of fiber filaments 1. The nozzles are located at the lower end of the row-type nozzle 6, and the nozzles are arranged in sequence along the first direction. The row-type nozzle 6 can reciprocate and translate along the second direction. Specifically, the row-type nozzle 6 is driven by a linear drive device on one side thereof, and reciprocates and translates at a constant speed along the second direction. More specifically, the linear drive device here can be an electric push rod, or the linear drive device can be a combination of a screw nut mechanism and a motor.

[0029] Specifically, the melting device can melt the raw material into a fluid material and output it. Taking the plastic melting device as an example, it usually adopts a plastic screw device, which can melt the raw material (plastic) and apply a constant pressure to the melted fluid material to extrude it from the discharge port (not shown in the figure) of the plastic melting device. The inner cavity (not shown in the figure) of the row-type nozzle 6 is connected to the discharge port (not shown in the figure) of the plastic melting device, and the lower part of the row-type nozzle 6 is provided with a spray hole connected to the inner cavity, spraying downward and with spraying directions parallel to each other.

[0030] The working table is located below the row nozzle 6 to receive the fiber filaments 1 discharged from the nozzle hole.

[0031] In this embodiment, the workbench is a rotatable rotating roller, and the central axis of the rotating roller is horizontal and perpendicular to the first direction. More specifically, the central axis of the rotating roller is parallel to the second direction. The workbench can rotate synchronously when the pattern nozzle 6 reciprocates and translates along the second direction, so that the fiber filaments 1 dropped on the workbench form the dropped filaments 2 arranged at an angle with the first direction, and the dropped filaments 2 are interwoven and shaped into a fiber web 3.

[0032] In some other embodiments, the workbench is a belt conveyor line whose surface can move along the first direction. Similarly, the belt conveyor line can move along the first direction synchronously when the pattern nozzle 6 moves back and forth along the second direction, so that the fiber filaments 1 dropped on the conveyor belt form dropped fibers 2 arranged at an angle to the first direction, and multiple dropped fibers 2 are interwoven and formed into a fiber web 3.

[0033] In this embodiment, a heating component is provided in the workbench, and a working surface for receiving the fiber filaments 1 is provided above the workbench. The heating component can heat the temperature of the working surface to a temperature not lower than the melting temperature of the fiber filaments 1. Taking the workbench as an example, the rotating roller can be called the receiving roller 7. The receiving roller 7 has a built-in heating component, and its surface is in a constant temperature state under the control of the linkage control system, and its surface temperature is not lower than the melting temperature of the raw materials used, and the receiving roller 7 is driven by its driving device to rotate at a constant speed; the receiving roller 7 is installed directly below the row-type nozzle 6, and is used to receive the row of fiber filaments 1 sprayed out by the row-type nozzle 6, so that they form parallel and non-overlapping falling wires 2 on the surface of the receiving roller 7.

[0034] The pulling device is used to pull the fiber web 3 formed at the workbench along the first direction. The pulling device is composed of a feeding roller assembly 8 and a pulling roller assembly 9, both of which are provided with heating components to keep their surface temperatures constant, and the surface temperature of the pulling roller assembly 9 is lower than that of the feeding roller assembly 8. The feeding roller assembly 8 and the pulling roller assembly 9 are both composed of an active roller 91 and a passive roller 92 close to the active roller 91, wherein the active roller 91 is driven by its driving device and rotates at a constant speed, driving the passive roller 92 to rotate synchronously; the linear speed of the pulling roller assembly 9 is greater than that of the feeding roller assembly 8, and the fiber web 3 passing between the two is pulled.

[0035] In this embodiment, the receiving roller 7, the feeding roller assembly 8 and the pulling roller assembly 9 are arranged in sequence along the first direction, and the central axes of the roller bodies are parallel to each other. A gradually decreasing temperature gradient is formed between the feeding roller assembly 8 and the pulling roller assembly 9.

[0036] The fiber web pulled by the pulling device forms a shaped fiber web 4, and the winding device 10 is used to store the shaped fiber web 4 in a cylindrical or stacked manner. Specifically, when the winding device 10 stores the shaped fiber web 4 in a cylindrical form, the winding device 10 includes Figure 1 The reel shown rolls the material placed thereon into a roll when it rotates.

[0037] In some embodiments, there are multiple row-type nozzles 6, and the multiple row-type nozzles 6 are distributed in sequence along the first direction or the second direction.

[0038] In this embodiment, when the workbench is a rotating roller, the lower ends of the nozzle holes on the row nozzle 6 are distributed along an arc track, and the arc track is coaxially arranged with the rotating roller. At this time, it is convenient to make the distance between different nozzle holes and the upper surface of the receiving roller 7 a constant value, and control the time and speed of the wire 2 falling at each position on the receiving roller 7 to be consistent.

[0039] Working principle: When in use, the melting device melts the raw materials and feeds the row nozzle 6. The row nozzle 6 moves back and forth at a constant speed in a direction parallel to the axial direction of the receiving roller 7, while spraying parallel and rowed fiber filaments 1. The receiving roller 7 rotates at a constant speed along its central axis and receives the fiber filaments 1 sprayed downward from the row nozzle 6. Under the two-dimensional movement of the row nozzle 6 and the receiving roller 7, the rows of fiber filaments 1 fall on the surface of the receiving roller 7 to be transformed into dropped filaments 2. Since the surface temperature of the receiving roller 7 is higher than the melting temperature of the fiber filaments 1, multiple strands of dropped filaments 2 cross each other and the intersection points 21 of the dropped filaments 2 fuse with each other to form a fiber web 3.

[0040] The feeding roller assembly 8 of the pulling device peels the fiber web 3 falling on the surface of the receiving roller 7 from the surface of the receiving roller 7, and is clamped by the active roller and the passive roller close to each other. Under the drive of the active roller and its driving device, the fiber web 3 (for clarity, Figure 1 The fiber web 3 is "rolled out" by the feeding roller assembly 8 (not shown in the figure) and moved to the pulling roller assembly 9. The pulling roller assembly 9 also clamps the fiber web 3 passing therethrough by its active roller and passive roller. Since the linear speed of the pulling roller assembly 9 is greater than that of the feeding roller assembly 8, and a gradually decreasing temperature gradient is formed between the feeding roller assembly 8 and the pulling roller assembly 9, the fiber web 3 therebetween is pulled and shaped after passing through the pulling roller assembly 9.

[0041] The winding device 10 is driven by its driving device to rotate at a constant linear speed, and its linear speed is equal to the linear speed of the pulling roller assembly 9, and the pulled and shaped drawn fiber web 3 is rolled into a roll to form a web tube 5, which is the finished product of this embodiment.

[0042] This embodiment also provides a method for manufacturing a fiber web 3, which utilizes the above-mentioned manufacturing device for the fiber web 3 and includes the following steps:

[0043] Step 1: Use a melting device to make the raw material enter a molten fluid state, so that the fluid material is sprayed downward from the discharge nozzle 6.

[0044] Step 2: the row-shaped nozzle 6 reciprocates along the second direction, and the working table moves so that its upper end reciprocates along the first direction. The unidirectional movement of the row-shaped nozzle 6 along the second direction forms parallel and non-overlapping dropped silks 2 on the working table, and the reciprocating movement of the row-shaped nozzle 6 along the second direction forms mutually intersecting dropped silks 2 on the working table to shape the fiber web 3.

[0045] Step 3, heating the workbench, combining with the residual temperature of the fiber filaments 1, to make the intersections 21 of the fiber web 3 melt together.

[0046] Step 4: The fiber web 3 is separated from the workbench and pulled in the discharge direction of the manufacturing device, and a pulling temperature lower than the workbench temperature is provided to the fiber web 3 during the pulling process. The fiber web 3 pulled out of the workbench is pulled in at least one direction so that the dropped fibers 2 constituting the fiber web 3 are pulled in a balanced manner.

[0047] Step 5, shaping the stretched fiber web 3, winding the shaped fiber web 3 into a roll, or reciprocatingly folding the fiber web 3 into a stack for storage.

[0048] Step 6, staggered lamination of the shaped fiber web 3, and the intersection positions of the dropped fibers 2 in adjacent layers are fused into interlayer intersection points 21 by heating.

[0049] Example 2

[0050] This embodiment is basically the same as the embodiment 1, except that an edge sealing nozzle 12 is added.

[0051] That is, in this embodiment, the edge sealing nozzle 12 is located above the workbench, and the fiber filaments 1 sprayed from the edge sealing nozzle 12 can merge with the two ends of the fiber web 3 along the second direction to form the side edges 11 of the fiber web 3 .

[0052] like Figure 2 FIG. 1 is a top view of the fiber web 3 during the forming process of the present embodiment. In the present embodiment, the fiber web 3 forming structure includes a row type nozzle 6, an edge sealing nozzle 12 and a guide roller 7. For the convenience of description, Figure 2 Specifically, a single edge sealing nozzle 12 can be used here, the edge sealing nozzle 12 extends along the second direction (which is also the axial direction of the receiving roller 7), and downward spraying ports are respectively arranged at both ends thereof to spray out the fiber filaments 1 for edge sealing.

[0053] The row-type nozzle 6 receives the fluid material from the plastic melting device and sprays out multiple parallel fiber filaments 1 through the spray hole. The fiber filaments 1 fall onto the surface of the receiving roller 7 to form dropped wires 2. The row-type nozzle 6 reciprocates and cooperates with the receiving roller 7 to roll along the B1 direction (i.e., the first direction). The dropped wires 2 are interwoven on the surface of the receiving roller 7 to form a fiber web 3. The surface of the receiving roller 7 provides a temperature for the dropped wires 2 to maintain melting, so that the intersections 21 of the dropped wires 2 melt each other and form a connecting buckle. At the same time, the fixed edge-sealing nozzle 12 sprays edge-sealing wire strips on both sides. The edge-sealing dropped wires 2 merge with the two edges of the fiber web 3 on the surface of the receiving roller 7, adding side edges 11 extending along the first direction to the fiber web 3, thereby increasing the overall strength of the fiber web 3.

[0054] Compared with the fiber web 3 made in Example 1, the fiber web 3 with side edges 11 made in this example has edge sealing and is not easy to fall apart. After being pulled, the side edges 11 are pulled with the maximum pulling ratio because the pulling direction is consistent with the extending direction of the side edges 11, and the other threads constituting the fiber web 3 are pulled in an oblique direction, so the pulling ratio they are subjected to is smaller than that of the side edges 11, and the elasticity is greater than that of the edge sealing.

[0055] Thus, the weak elasticity of the side edge 11 is utilized to protect the strong elasticity of the center of the fiber web 3, so that the elasticity of the center of the fiber web 3 is protected during packaging, transportation, cutting, and before being put into use.

[0056] Example 3

[0057] This embodiment is basically the same as Embodiment 2, except that, based on Embodiment 2, the edge sealing nozzle 12 is not only provided with spray holes on both sides thereof along the second direction, but also has a plurality of spray holes arranged at fixed points or evenly in the width direction of the corresponding fiber web 3 (i.e., along the second direction of the edge sealing nozzle 12).

[0058] When working, the fiber filaments 1 ejected from the edge sealing nozzle 12 not only provide the side edges 11 for the fiber web 3, but also add the side edges 11 at fixed points or evenly in the central area of ​​the fiber web 3. Figure 2 The wire edges are parallel to the direction B1 and are fused with the fiber web 3 at the intersection 21 with the fiber web 3, playing the role of reinforcing ribs, making the strength of the finished fiber web 3 higher; the mesh count of the fiber web 3 is increased, making the fiber web 3 more "denser".

[0059] Example 4

[0060] This embodiment also provides a device for manufacturing a fiber web 3, which has the function of keeping the width of the finished fiber web 3 unchanged or increasing after being pulled by the pulling device.

[0061] like Figure 3 As shown, and refer to Figure 1 The pulling roller assembly 9 of the pulling device is composed of an active roller 91, a passive roller 92, a power device (not shown in the figure) for driving the active roller 91, an adjusting device (not shown in the figure), and a frame (not shown in the figure) for assembling the above components, wherein:

[0062] The adjusting device is used to adjust the gap between the active roller 91 and the passive roller 92. When starting to work, the adjusting device is operated to increase the gap between the active roller 91 and the passive roller 92 so that the beginning of the fiber web 3 can enter the gap, and then the adjusting device is operated to make the active roller 91 and the passive roller 92 close to each other. The power of the power device is transmitted from the active roller 91 to the passive roller 92, so that the two rollers run at the same linear speed and generate a clamping force to drag the fiber web 3 forward; at the same time, by making the linear speed of the pulling roller assembly 9 greater than the feeding roller assembly 8, the fiber web 3 passing through the feeding roller assembly 8 and the pulling roller assembly 9 is pulled.

[0063] In this embodiment, active grooves 911 are provided at both ends of the active roller 91, and passive grooves 921 are provided at corresponding positions of the passive roller 92. When the fiber web 3 is manufactured in accordance with Embodiments 2 and 3, the side edge 11 of the fiber web 3 can be thickened by adjusting the spinning speed of the edge sealing nozzle 12. That is, the thickness of the side edge 11 of the fiber web 3 is greater than the thickness of the portion other than the side edge 11.

[0064] When the machine is turned on for feeding, the side edge 11 is inserted into the groove formed by the active groove 911 and the passive groove 921. During the pulling process of the fiber web 3, the width of the fiber web 3 will inevitably shrink, and the setting of the groove can effectively prevent the width of the fiber web 3 from shrinking and play a role in fixing the width. Correspondingly, the feeding roller assembly 8 of the pulling device is also provided with the groove, which will not be described here.

[0065] In other embodiments, Figure 4 As shown, and refer to Figure 3 Between the feeding roller assembly 8 and the pulling roller assembly 9 of the pulling device, there is an expansion assembly 13, which is pressed against the two side edges 11 of the fiber web 3 by a tensioning mechanism through multiple squeezing rollers 131. The rotation direction E2 of the squeezing rollers 131 is not parallel to the traveling direction B1 of the fiber web 3. When the squeezing rollers 131 rotate, a rubbing force in the direction of increasing the width is applied to the side edges 11 of the fiber web 3 to offset the width contraction that may be caused by pulling. Figure 3 Similar amplitude effect.

[0066] Example 5

[0067] This embodiment also provides a manufacturing device for a fiber web 3, which is different from the above embodiment in that: Figure 5 As shown, in order to prevent the dropped fibers 2 from adhering to the receiving roller 7 during continuous operation, causing the fiber web 3 to break or fracture, this embodiment includes a release agent supply part and a separation component, wherein the release agent supply part can spray the release agent on the workbench before the workbench receives the fiber filaments 1. The separation component can peel the shaped fiber web 3 from the workbench, and the separation component is installed between the workbench and the pulling device.

[0068] The release agent supply component here includes a brushing groove 15, and the separation component includes a demoulding shovel 14.

[0069] Specifically, the brushing groove 15 is fixed below the receiving roller 7, and a release agent is provided in the brushing groove 15, and the liquid level of the release agent is slightly higher than the lower surface of the receiving roller 7. When the receiving roller 7 rotates, its surface will be circulated and immersed in the release agent, so that a layer of release agent is covered on the surface, so as to facilitate the peeling of the fiber web 3 landed thereon from its surface.

[0070] In order to control the thickness of the release agent 151 attached to the surface of the receiving roller 7, a scraper 152 is provided on the side 11 of the brushing groove 15 to scrape off the excess release agent 151 and return it to the brushing groove 15. The stripping shovel 14 is fixed on the upper side of the receiving roller 7, corresponding to the position where the fiber web 3 is peeled off the surface of the receiving roller 7. It is a wedge-shaped scraper that wedges into the fiber web 3 and the receiving roller 7 to assist in peeling the fiber web 3 from the surface of the receiving roller 7.

[0071] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.

[0072] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
