Description

Technical Field

[0001] The present invention relates to the technical field of 3D clothing printing equipment, and in particular to a printer and a method for manufacturing a flat fabric of clothing. Background Art

[0002] The application of 3D printing in the field of clothing can realize personalized, three-dimensional, complex and difficult production of clothing, so it is becoming more and more popular. The existing fused deposition modeling method (FDM, Fused Deposition Modeling) is to extrude filamentary materials (such as thermoplastics, wax or metal filaments) from a heated nozzle, and melt deposit at a fixed rate according to the predetermined trajectory of each layer of the part. After each layer is completed, the workbench drops a layer thickness to deposit a new layer, and this is repeated to finally achieve the deposition molding of the part. Since the filamentary material ejected from the nozzle is regular, and moves according to the predetermined trajectory and stacks layer by layer, this spinning process has high requirements on the accuracy of the equipment and is difficult to operate, resulting in low clothing printing efficiency and increased manufacturing costs. In addition, the FDM process generally keeps the temperature of the semi-fluid molding material just above the melting point (about 1°C higher than the melting point) so that adjacent layers can rely on the material itself to bond. The clothing made by this method has low strength and poor user experience.

[0003] Therefore, there is a need to design a printer that is easy to operate and can produce garments with high strength. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems of greater operating difficulty and lower clothing strength in the prior art, and to provide a printer that is easy to operate and can produce clothing with higher strength.

[0007] In the above technical solution, since the fibers sprayed onto the mesh base do not need to be arranged regularly, compared with the process of spraying along a predetermined trajectory to form regularly arranged filamentary materials and stacking them layer by layer, the requirements for equipment accuracy are reduced, and the operating difficulty is reduced accordingly, thereby significantly improving the printing efficiency of clothing and reducing costs to a certain extent. In addition, the fibers can be entangled through the water spunlace process.

[0033] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0034] In the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to the up, down, left, right shown in the reference drawings; "inside, outside" refer to the inside and outside relative to the outline of each component itself.

[0035] On one hand, the present invention provides a printer, which includes a mesh base plate 1, a first nozzle 2 arranged above the mesh base plate 1 for spraying fibers onto the mesh base plate 1 to print on flat fabrics of clothing, and a water-entanglement device for water-entangling the flat fabric on the mesh base plate 1 through the mesh holes on the mesh base plate 1 to entangle the fibers.

[0036] The diameter of the nozzle hole of the first nozzle 2 can be 0.1-0.5 mm, and the first nozzle 2 needs to be a high temperature resistant nozzle and can be equipped with an air pump, which is conducive to the polymer forming a uniform fiber mesh under a certain temperature and pressure. In addition, the first nozzle 2 can be made of stainless steel, nickel-based alloy, Hastelloy and other materials; the mesh bottom plate 1 can be made of stainless steel, rare metals and other materials.

[0037] In the above technical scheme, since the fibers sprayed on the mesh base plate 1 do not need to be arranged regularly, compared with the process of spraying according to a predetermined trajectory to form regularly arranged filamentary materials and stacking them layer by layer, the requirements for equipment accuracy are reduced, and the operating difficulty is reduced accordingly, thereby significantly improving the printing efficiency of clothing and reducing costs to a certain extent. In addition, the fibers can be entangled through the water entanglement process (water entanglement is a technology that uses high-pressure sprayed fine water streams to make fibers cross each other and entangled into a web). Compared with the method of relying on the bonding of each layer of material itself, the strength of the clothing is higher and can better meet user needs.

[0038] like Figure 1-2 and Figure 5-6 As shown, preferably, the water entanglement device includes a water spray pipe 31 and a water pump 32 connected to the water spray pipe 31, and the water spray pipe 31 is provided with a plurality of water spray holes H for water entanglement. In order to ensure that the water flow sprayed from the water spray holes H on the water spray pipe 31 can smoothly pass through the mesh bottom plate 1 to perform water entanglement on the fiber material on the mesh bottom plate 1, the water spray holes H are arranged on the pipe wall of the water spray pipe 31 facing the mesh bottom plate 1. In this way, the water flow with a certain pressure sprayed by the water pump 32 can be sprayed when passing through the water spray holes H on the water spray pipe 31 to perform water entanglement on the fiber material printed on the mesh bottom plate 1, so as to entangle the fiber material to improve the strength of the flat fabric.

[0039] There are various options for the arrangement of the water jet pipes 31 for hydroentangling below the mesh bottom plate 1. Preferably, the part of the water jet pipes 31 corresponding to the mesh bottom plate 1 is a plurality of linearly arranged pipes connected to each other in rows, such as Figure 2 the matrix arrangement shown, Figure 3 the arrangement similar to the shape of "ji" shown (wherein, in order to make the water ejected from the water jet holes H have a certain pressure, the first end a of the pipe is connected to the water pump 32, and the second end b can be closed), and Figure 4 the arrangement in which the first ends of the multi-row branch pipes N shown are connected to the same main pipe M (wherein, in order to make the water ejected from the water jet holes H have a certain pressure, the second ends of the multi-row branch pipes N can be closed, the first end c of the main pipe M is connected to the water pump 32, and the second end d can be closed or connected to the first end of one of the branch pipes N), or the part of the water jet pipes 31 corresponding to the mesh bottom plate 1 is a multi-loop coiled pipe connected to each other, such as Figure 6 the arrangement in which a plurality of annular pipes E shown are sleeved together and connected to the same water inlet pipe F, and Figure 7 the spiral arrangement shown (wherein one end inside the spiral pipe can be closed, and the other end outside can be connected to the water pump 32).

[0040] In addition, the installation position of the hydroentangling device relative to the mesh bottom plate 1 can have but is not limited to the following two implementation manners.

[0041] The first implementation manner

[0042] Preferably, the hydroentangling device is arranged above the mesh bottom plate 1, and the hydroentangling device hydroentangles the planar fabric from top to bottom. In this way, the water ejected by the hydroentangling device will flow directly downward after passing through the planar fabric, which is convenient for collecting and centrally treating the water after hydroentangling. Since the first nozzle 2 is also arranged above the mesh bottom plate 1, when interference occurs when the first nozzle 2 and the hydroentangling device are both in the working position, both the first nozzle 2 and the hydroentangling device can be set to be movable. In this way, when the first nozzle 2 needs to work, the hydroentangling device can be moved away, and the first nozzle 2 can be moved above the mesh bottom plate 1; when the hydroentangling device needs to work, the first nozzle 2 can be moved away, and the hydroentangling device can be moved above the mesh bottom plate 1.

[0043] In order to facilitate the collection of water after hydroentanglement, preferably, a water storage tank 4 for recovering the water sprayed by hydroentanglement is provided below the mesh bottom plate 1, and in order to enable the water after hydroentanglement to be recycled and used to reduce costs, the water storage tank 4 is connected to the water pump 32 to circulate water to the water pump 32. Furthermore, since the water after hydroentanglement generally contains impurities, in order to avoid blockage, a soft water treatment device for filtering, such as a filter, is provided between the water storage tank 4 and the water pump 32, and in order to quickly and centrally collect the water in the water storage tank 4, a water absorbing device for collecting water, such as a sponge, can be provided between the water storage tank 4 and the water pump 32. Of course, it can be understood that the soft water treatment device and the water absorbing device can also be other relatively complex devices that can achieve filtering or water collection functions.

[0044] Second implementation method

[0045] like Figure 1 and Figure 5 As shown, preferably, the hydroentanglement device is arranged below the mesh bottom plate 1, and the hydroentanglement device hydroentangles the fibrous material from bottom to top. In this way, the installation position of the hydroentanglement device is relatively low, which is convenient for connection with a water source. Since the hydroentanglement device hydroentangles the fibrous material from bottom to top, a part of the water sprayed upward from the hydroentanglement device will fall back after passing through the mesh bottom plate 1 to entangle the flat fabric. In addition, another part of the water sprayed upward from the hydroentanglement device may also flow downward due to the obstruction of the mesh bottom plate 1. Therefore, in order to facilitate the collection of these two parts of water sprayed from the hydroentanglement device, preferably, the printer includes a water storage tank 4 arranged below the mesh bottom plate 1. At the same time, in order to collect part of the water that falls directly after being sprayed from the water spray pipe 31 without reaching the mesh bottom plate 1, the water spray pipe 31 is arranged in the water storage tank 4. In order to recycle the water after hydroentanglement to reduce costs, the water storage tank 4 is connected to the water pump 32 to circulate water to the water pump 32, such as Figure 1 and Figure 5 As shown, the water tank 4 is provided with a water outlet 41, and the water stored in the water tank 4 can be provided to the water pump 32 through the water outlet 41. In addition, in order to fix the water spray pipe 31, a mesh structure can be provided on the top surface of the water tank 4, and the water spray pipe 31 can be tied to the mesh structure by a belt.

[0046] Furthermore, since the water after hydroentanglement generally contains impurities, in order to avoid blockage, a soft water treatment device for filtering, such as a filter, is provided between the water storage tank 4 and the water pump 32, and in order to quickly collect the water in the water storage tank 4, a water absorbing device for collecting water, such as a sponge, can be provided between the water storage tank 4 and the water pump 32. Of course, it can be understood that the soft water treatment device and the water absorbing device can also be other relatively complex devices that can achieve filtering or water collection functions.

[0047] The number of water spray holes H per unit area can be set according to the strength requirements of the flat fabric to perform different degrees of entanglement. In order to enable the mesh bottom plate 1 to meet different degrees of entanglement requirements, preferably, the opening rate of the mesh bottom plate 1 is 20%-80%.

[0048] In addition, in order to facilitate the determination of the shape of the planar fabric printed by the first nozzle 2, preferably, the printer includes a second nozzle 5 for printing a groove having the outer contour of the planar fabric. Wherein, "a groove having the outer contour of the planar fabric" means that the shape surrounded by the inner circumferential wall of the groove is consistent with the outer contour of the planar fabric. In addition, the second nozzle 5 can be a common fused deposition modeling (FDM) nozzle, and the nozzle hole diameter of the nozzle 5 can be 0.1-0.5mm.

[0049] Specifically, the second nozzle 5 can be used to print a groove with the outer contour of the plane fabric first, that is, the outer contour of the plane fabric to be printed is predetermined by the groove, and then the first nozzle 2 is used to print the plane fabric in the groove, so that the plane fabric printed in the groove is the contour shape of the groove. After the plane fabric is printed, it can be spunlace. Preferably, the second nozzle 5 can spray water-soluble consumables, so that during the spunlace process, the printed groove may be partially dissolved. In order to completely dissolve it, the groove can be sprayed with water again, and finally the desired plane fabric is obtained. After further processing such as drying, sewing and rough edges, customized clothing can be obtained.

[0050] The second aspect of the present invention provides a method for manufacturing a flat fabric of clothing, the manufacturing method uses the above-mentioned printer, and the manufacturing method comprises: step S2, spraying fibers on the mesh bottom plate 1 through the first nozzle 2 to print the flat fabric of clothing; step S4, using a hydroentanglement device to hydroentangle the flat fabric on the mesh bottom plate 1 through the mesh holes on the mesh bottom plate 1 to entangle the fibers. Since the fibers sprayed on the mesh bottom plate 1 do not need to be arranged regularly, compared with the process of spraying according to a predetermined trajectory to form regularly arranged filamentary materials and stacking them layer by layer, the requirements for equipment accuracy are reduced, and the difficulty of operation is reduced accordingly, thereby significantly improving the printing efficiency of clothing and reducing costs to a certain extent. In addition, the fibers can be entangled through the hydroentanglement process. Compared with the method of relying on the bonding of each layer of material itself, the strength of the clothing is higher and can better meet user needs.

[0051] In order to improve the quality of the flat fabric by better water injection and spunlace, preferably, the manufacturing method includes: step S3, pre-wetting the flat fabric printed in step S2 and / or removing bubbles, and step S3 is before step S4. The pre-wetting treatment can be performed by spraying water with a watering can, and the bubble removal can be performed by hand pressing.

[0052] In order to obtain a flat fabric of a desired shape, preferably, the manufacturing method comprises: step S1, printing a groove having the outer contour of the flat fabric on the mesh bottom plate 1 by the second nozzle 5, and in step S2, the first nozzle 2 sprays in the groove for printing. Wherein, "a groove having the outer contour of the flat fabric" means that the shape surrounded by the inner peripheral wall of the groove is consistent with the outer contour of the flat fabric.

[0053] The groove sprayed by the second nozzle 5 is to determine the outer contour of the plane fabric to be printed, so that the first nozzle 2 can spray the fiber material in the groove to obtain the plane fabric of the desired shape. Although the outer contour may be partially dissolved in the hydroentanglement process of step S4, in order to completely dissolve the outer contour to obtain the desired plane fabric, preferably, the manufacturing method includes: step S5, dissolving the groove formed in step S1, and step S5 is after step S4. After obtaining the desired plane fabric, customized clothing can be obtained after further processing such as drying, sewing and rough edges.

[0054] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
