Description

Technical Field

[0001] This utility model relates to the field of spunlace fabric production technology, and more specifically, to a combined spunlace fabric production device. Background Technology

[0002] Spunlace fabric, also known as hydroentangled nonwoven fabric, is a fabric made by spraying high-pressure micro-jet water onto one or more layers of fiber web, causing the fibers to entangle together. With technological advancements and widespread application, washable spunlace nonwoven fabric is increasingly favored by the market.

[0003] Currently, in the production of spunlace fabric, a single spunlace curtain is used to support and coordinate with multiple spunlace heads to reinforce the fiber web. During hydroentangling, water flows through small holes in the water jet plates of the spunlace heads and is directed at the fiber web. This works in conjunction with the spunlace curtain below the lower fiber web. The spunlace curtain, also called a conveyor curtain or drag curtain, is woven from stainless steel wire, high-strength polyamide, and polyester monofilament according to the required mesh count, pattern, and specifications. It supports and conveys the fiber web. Pattern hydroentangling is then performed, where different structures and mesh counts of the curtain create different patterns on the spunlace product, giving it a specific design and the appearance of traditional textile fabrics. During hydroentangling, the curtain reflects the high-pressure water jets, further reinforcing the fiber web.

[0004] The shortcomings of the existing technology are: the combination of water needle plate and spunlace mesh curtain is not flexible. Although the water needle plate on the spunlace head is easy to replace, the spunlace mesh curtain has a large area and is not easy to replace. Only one pattern or specification of spunlace mesh curtain can be used each time spunlace is produced. The spunlace reinforcement process is simple and it is not convenient to produce spunlace fabric products with multiple reinforcement methods or multiple patterns.

[0005] In view of this, the applicant has studied and improved the existing problems and proposed a hydrospunlace fabric hydrospunlace combination device. Different hydrospunlace units can be matched with different hydrospunlace curtains to achieve the diversity of reinforcement methods when hydrospunlace is reinforced, and is no longer limited to using only one hydrospunlace curtain. Utility Model Content

[0006] This invention provides a hydroentangled fabric and hydroentangled fabric combination device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A spunlace fabric assembly includes multiple spunlace units, each including an upper spunlace head and a lower spunlace mesh curtain. The spunlace head and the spunlace mesh curtain of each spunlace unit are correspondingly matched. Multiple drive rollers are arranged inside the spunlace mesh curtain of each spunlace unit. The spunlace mesh curtain is wound around the multiple drive rollers and driven to rotate circumferentially by the drive rollers. A vacuum suction device is arranged on the inner side of the spunlace mesh curtain near the spunlace head, which is correspondingly matched with the spunlace head. The vacuum suction device removes the water from the spunlace reinforcement so that the fiber web can be reinforced for the next spunlace step.

[0009] By incorporating spunlace heads, spunlace curtains, and vacuum suction devices in each spunlace unit to complete the spunlace process, the spunlace curtains are miniaturized for easy replacement. This allows for flexible combinations of different needle plates and spunlace curtains across different spunlace units, achieving diversity in spunlace reinforcement methods and moving beyond the limitation of using only one spunlace curtain in the spunlace process during production. The spunlace curtains in each unit can use, but are not limited to, plain weave, twill weave, satin weave, coarse wire diameter weave, fine wire diameter weave, multi-layer weave, and single-layer weave. The needle plates can use, but are not limited to, needle hole sizes of 0.08mm, 0.1mm, 0.12mm, and 0.14mm, single-row holes, double-row holes, large hole spacing, and small hole spacing. This approach integrates the advantages of various needle plates into a single production run of washable spunlace fabric, giving it the benefits of multiple needle plates and increasing its quality and market competitiveness.

[0010] Preferably, the hydroentangling unit has two or more hydroentangling heads, and correspondingly two or more vacuum suction devices. This allows the other hydroentangling heads to be used while the water needle plate of one hydroentangling head is being cleaned and maintained, without affecting production.

[0011] Preferably, the multiple drive rollers of the hydroentangled mesh curtain of the hydroentangled unit are connected by a bracket, which includes a transverse support frame and longitudinal support frames disposed at both ends of the transverse support frame. Both the transverse support frame and the longitudinal support frame are telescopic and adjustable support frames.

[0012] The telescopic adjustable support frame includes a first frame and a second frame that are slidably connected, and a telescopic drive device is provided between the two frames to drive and control the telescopic distance between the two frames.

[0013] The telescopic drive device can be a telescopic hydraulic cylinder, a telescopic pneumatic cylinder, or an electric telescopic rod, etc.

[0014] The transverse support frame includes a first transverse support frame and a second transverse support frame. The two ends of the first transverse support frame are connected to the fixed ends of the two longitudinal support frames at both ends, and the two ends of the second transverse support frame are connected to the movable ends of the two longitudinal support frames at both ends.

[0015] The vacuum suction device is mounted on a second transverse support frame and moves up and down with the longitudinal support frame, maintaining a relative distance from the spunlace mesh curtain on its side.

[0016] The design of the telescopic and adjustable support frame allows for easy replacement of the spunlace mesh curtain. After replacement, the telescopic and adjustable support frame is restored to its working state, saving replacement time and improving production adjustment efficiency.

[0017] This utility model has the characteristics of simple structure, strong practicality and good use effect, and is worth promoting and using widely. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figure 1A spunlace fabric assembly includes multiple spunlace units 1, each spunlace unit 1 comprising an upper spunlace head 2 and a lower spunlace mesh curtain 3. The spunlace head 2 of each spunlace unit 1 corresponds to and engages with the spunlace mesh curtain 3. Multiple drive rollers 4 are arranged inside the spunlace mesh curtain 3 of each spunlace unit 1, and the spunlace mesh curtain 3 is wound around the multiple drive rollers 4, driving the spunlace mesh curtain 3 to rotate circumferentially. A vacuum suction device 5 is arranged on the inner side of the spunlace mesh curtain 3 near the spunlace head 2, corresponding to and engaging with the spunlace head 2. The vacuum suction device 5 removes the water from the spunlace reinforcement of the corresponding spunlace head 2, allowing the fiber web to proceed to the next spunlace reinforcement stage. Preferably, in this embodiment, the spunlace unit 1 has two spunlace heads 2 and two corresponding vacuum suction devices 5, so that when the water needle plate of one spunlace head is being cleaned and maintained, the other spunlace head can still be used without affecting production. By equipping each hydroentanglement unit 1 with a hydroentanglement head 2, a hydroentanglement mesh curtain 3, and a vacuum suction device 5 to complete the hydroentanglement operation, the hydroentanglement mesh curtain 3 is miniaturized for easy replacement. This allows for flexible combinations of different hydroentanglement units 1 with different hydroentanglement needle plates and hydroentanglement mesh curtains, achieving diversity in hydroentanglement reinforcement methods and eliminating the limitation of using only one hydroentanglement mesh curtain during production. The hydroentanglement mesh curtain 3 of each hydroentanglement unit 1 can use, but is not limited to, any of the following: plain weave, twill weave, satin weave, coarse wire diameter weave, fine wire diameter weave, multi-layer weave, or single-layer weave. The hydroentanglement needle plate can use, but is not limited to, any of the following: needle hole diameters of 0.08mm, 0.1mm, 0.12mm, 0.14mm, single row holes, double row holes, large hole spacing, or small hole spacing. For example, one spunlace unit uses a coarse-diameter spunlace curtain, another uses a fine-diameter spunlace curtain, and yet another uses multiple layers of spunlace curtain. The coarse-diameter spunlace curtain has a uniform fiber distribution throughout the web, while the fine-diameter spunlace curtain has a delicate fabric surface with less shedding. The multiple layers of spunlace curtain have a high water needle reflection energy and a high water needle energy utilization rate. This can combine the advantages of various curtains in a single production of washable spunlace fabric, giving the washable spunlace fabric the advantages of multiple curtains, thus increasing the quality and market competitiveness of the washable spunlace fabric.

[0022] In practical applications, it is not limited to these three methods and three spunlace units; it can be a combination of more spunlace units and more spunlace reinforcement methods.

[0023] As a further preferred embodiment, the multiple drive rollers 4 of the spunlace mesh curtain 3 in the spunlace unit 1 are connected by a bracket 6. The bracket 6 includes a transverse support frame 61 and longitudinal support frames 62 disposed at both ends of the transverse support frame 61. Both the transverse support frame 61 and the longitudinal support frame 62 are telescopic and adjustable support frames. By telescopically extending and retracting the transverse support frame 61 and / or the longitudinal support frame 62, the telescopic and adjustable support frames retract when the spunlace mesh curtain 3 is replaced, facilitating the replacement of the spunlace mesh curtain 3. After replacement, the telescopic and adjustable support frames return to their working state through a support mechanism, saving replacement time for the spunlace mesh curtain 3 and improving production adjustment efficiency.

[0024] Specifically, in this embodiment, taking the transverse support frame 61 as an example, the telescopic adjustable support frame includes a first frame 611 and a second frame 612 that are slidably connected. A telescopic drive device 613 is provided between the two frames to drive and control the telescopic distance between the two frames. The telescopic drive device 613 can be any of a telescopic hydraulic cylinder, a telescopic pneumatic cylinder, or an electric telescopic rod.

[0025] In a further preferred embodiment, the transverse support frame 61 includes a first transverse support frame and a second transverse support frame 6-1. The two ends of the first transverse support frame are connected to the fixed ends of the two longitudinal support frames 62 at both ends, and the two ends of the second transverse support frame 6-1 are connected to the movable ends of the two longitudinal support frames 62 at both ends. The vacuum suction device 5 is mounted on the second transverse support frame 6-1 and moves up and down with the longitudinal support frame, maintaining a relative distance from the spunlace mesh curtain 3 on its side.

[0026] The inventive concept of this utility model lies in the simultaneous use of multiple spunlace mesh reinforcement processes during the spunlace production process, so that the advantages of most spunlace meshes are concentrated in a single spunlace fabric that can be washed away.

[0027] In practical applications, it is not limited to three sets of spunlace units; multiple sets of spunlace units can be set according to the actual production needs of the factory. It is not limited to only two spunlace machines and vacuum suction devices in each spunlace unit; multiple sets can be set according to the actual production needs of the factory. The combination of spunlace mesh curtains and spunlace needle plates is not limited to the embodiments in the application documents; they can be freely combined and configured in many other ways according to production design requirements.

[0028] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
