Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing, and in particular to a damping device for nonwoven fabric processing. Background Technology

[0002] Also known as nonwoven fabric, it is a sheet, web or pad made of fibers arranged in a directional or random manner, which are bonded together by friction, cohesion or bonding. It has many advantages such as moisture-proof, breathable, flexible, lightweight, non-flammable and non-toxic and non-irritating.

[0003] During the processing of nonwoven fabrics, it is usually necessary to wet them. Wetting the nonwoven fabric can prevent static electricity, improve fiber dispersion, and improve product quality. Due to the good water permeability of nonwoven fabrics, the process of wetting is usually done by placing a nozzle above the nonwoven fabric during the winding process. The nozzle is used to spray water evenly onto the surface of the nonwoven fabric to achieve the purpose of wetting.

[0004] Most existing nonwoven fabric wetting devices work by placing a nozzle above the nonwoven fabric and spraying water to wet it. However, this method is not very precise in controlling the amount of water sprayed from the nozzle. Also, because the nozzle has a large spray range, some water will spray off the sides of the nonwoven fabric, preventing it from reaching the surface and resulting in water waste.

[0005] Therefore, it is necessary to provide a new wetting device for nonwoven fabric processing to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a wetting device for non-woven fabric processing.

[0007] The present invention provides a wetting device for nonwoven fabric processing, comprising a housing, with inlets and outlets on both sides of the housing. Take-up rollers are rotatably connected to both sides of the housing near the inlets and outlets via a frame. A nonwoven fabric body is wound between the take-up rollers. A fixed motor for driving one of the take-up rollers is provided on one side of the housing. Two vertically arranged rotating drums are rotatably connected inside the housing. Several evenly distributed water outlet pipes are fixedly connected to the rotating drums. An installation groove is provided at the end of each water outlet pipe away from the rotating drum. A nozzle communicating with the installation groove is fixedly connected to the outer side of each water outlet pipe.

[0008] A movable seat is slidably connected inside the mounting groove. A spring is fixedly connected between the movable seat and the inner wall of the mounting groove. Several water inlet holes are opened at one end of the movable seat near the rotating cylinder. The side of the movable seat is provided with the same number of water outlet holes as the water inlet holes. The water outlet holes are interconnected with the water inlet holes on the same side.

[0009] Preferably, two connectors are rotatably connected to one side of the outer casing, a water pump is fixedly connected to the inner bottom wall of the outer casing, and a water supply pipe is fixedly connected between the water pump and the two connectors.

[0010] Preferably, the rotating drum has a water inlet at one end near the connector, and the water inlet of each rotating drum is connected to the connector on the same side.

[0011] Preferably, a mounting bracket A is fixedly connected to the side of the outer casing away from the connector, a pulley A is rotatably connected inside the mounting bracket A, the pulley A is fixedly connected to the end of the rotating drum on the same side, a pulley B is rotatably connected to the side of the outer casing close to the mounting bracket A, a transmission belt is provided between the pulley A and the pulley B, and a rotary motor for driving the pulley A to rotate is fixedly connected to the mounting bracket A.

[0012] Preferably, a gear A is fixedly connected to the end of the pulley B away from the outer casing, and a mounting frame B is fixedly connected to the side of the outer casing near the mounting frame A. A gear B is rotatably connected inside the mounting frame B, and the gear B is fixedly connected to the end of the rotating drum on the same side. The gear B and the gear A mesh with each other.

[0013] Preferably, a partition is fixedly connected inside the outer shell, the partition is located below the rotating cylinder, and the partition has a plurality of leakage holes.

[0014] Compared with related technologies, the wetting device for nonwoven fabric processing provided by this utility model has the following beneficial effects:

[0015] In the process of winding nonwoven fabric, this invention uses a rotary motor to drive two rotating drums. When the movable seats inside the water outlet pipes on the upper and lower drums come into contact with each other, they move towards the mounting groove due to compression. Then, the water outlet of the movable seat connects with the nozzle on the water outlet pipe. At this time, the water in the drums is sprayed out through the water inlet, water outlet, and nozzle, and sprayed onto the upper and lower surfaces of the nonwoven fabric. When the movable seats inside the water outlet pipes of the upper and lower drums separate, the spring rebounds due to the disappearance of the compression force on the movable seats, causing the movable seats to extend out of the water outlet pipe. At this time, the water outlet of the movable seat is misaligned with the nozzle, and the water outlet of the movable seat is sealed by the inner wall of the mounting groove. This stops the water in the drums from being discharged through the water outlet pipe, avoiding the problem of imprecise water volume control in traditional devices, and effectively improving the water conservation of this device.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 6 The present invention provides a wettability device for nonwoven fabric processing, comprising a housing 1, wherein inlet and outlet 11 are provided on both sides of the housing 1, and take-up rollers 2 are rotatably connected to the two sides of the housing 1 near the inlet and outlet 11 via a frame, wherein a nonwoven fabric body 21 is wound between the take-up rollers 2, and a fixed motor 22 is provided on one side of the housing 1 for driving one of the take-up rollers 2 to rotate.

[0026] It should be noted that the outer shell 1 is one of the main structures of the wetting device. It has good sealing performance and stores clean water inside for wetting the non-woven fabric 21. When wetting the non-woven fabric, the non-woven fabric 21 is first wound onto the take-up roller 2 on the side away from the fixed motor 22. Then, one end of the non-woven fabric 21 is passed through the inlet and outlet 11 and wound onto the take-up roller 2 on the side close to the fixed motor 22. Then, the fixed motor 22 is started, which drives the take-up roller 2 connected to it to rotate. At this time, the take-up roller 2 can take up the non-woven fabric 21 on the other take-up roller 2 during the rotation process, so that the part of the non-woven fabric 21 inside the outer shell 1 is always in a state of uniform speed movement, which facilitates the subsequent uniform wetting of the non-woven fabric 21.

[0027] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The outer casing 1 contains two vertically arranged rotating cylinders 3 rotatably connected to it. Several evenly distributed water outlet pipes 4 are fixedly connected to each rotating cylinder 3. An installation groove 41 is provided at the end of each water outlet pipe 4 away from the rotating cylinder 3. A nozzle 42 communicating with the installation groove 41 is fixedly connected to the outer side of each water outlet pipe 4. A movable seat 43 is slidably connected within the installation groove 41. A spring 44 is fixedly connected between the movable seat 43 and the inner wall of the installation groove 41. Several water inlet holes 45 are provided at the end of the movable seat 43 near the rotating cylinder 3. The side of the movable seat 43 has the same number of water outlet holes 46 as the water inlet holes 45, and the water outlet holes 46 communicate with the water inlet holes 45 on the same side. Two connectors 6 are rotatably connected to one side of the outer casing 1. A water pump 61 is fixedly connected to the inner bottom wall of the outer casing 1. A water supply pipe 62 is fixedly connected between the water pump 61 and each of the two connectors 6. The rotating cylinder 3 has a nozzle 42 at the end near the connectors 6. Each rotating drum 3 has a water inlet 31, and the water inlet 31 of each rotating drum 3 is connected to the connector 6 on the same side. A mounting bracket A5 is fixedly connected to the side of the outer shell 1 away from the connector 6. A pulley A51 is rotatably connected inside the mounting bracket A5. The pulley A51 is fixedly connected to the end of the rotating drum 3 on the same side. A pulley B52 is rotatably connected to the side of the outer shell 1 near the mounting bracket A5. A transmission belt 53 is provided between the pulley A51 and the pulley B52. A rotary motor 57 for driving the pulley A51 to rotate is fixedly connected to the mounting bracket A5. A gear A54 is fixedly connected to the end of the pulley B52 away from the outer shell 1. A mounting bracket B55 is fixedly connected to the side of the outer shell 1 near the mounting bracket A5. A gear B56 is rotatably connected inside the mounting bracket B55. The gear B56 is fixedly connected to the end of the rotating drum 3 on the same side. The gear B56 and the gear A54 mesh with each other.

[0028] It should be noted that when wetting the nonwoven fabric 21, the rotary motor 57 is first started, which drives the pulley A51 to rotate. The pulley A51, through the transmission belt 53, drives the pulley B52 and gear A54 to rotate in the same direction and at the same speed. During this process, gear A54 drives gear B56, which meshes with it, to rotate in the opposite direction and at the same speed. At this time, through the cooperation of gear A54 and gear B56, the two rotating drums 3 are driven to rotate in opposite directions. At this time, the water pump 61 is started, which delivers water from the outer shell 1 into the rotating drums 3 through the water pipe 62 and the connector 6, filling the rotating drums 3 with water. Then, when the rotating drums 3 rotate and the water outlet pipes 4 between the two rotating drums 3 are aligned, the two movable seats 43 press against each other through the nonwoven fabric 21, causing the movable seats 43 to retract into the mounting groove 41 and compress the spring 44. At this time, the water outlet holes 46 on the movable seats 43 open. The water in the rotating drum 3 will be connected to the nozzle 42. At this time, the water in the rotating drum 3 will be sprayed out through the water inlet 45, the water outlet 46 and the nozzle 42. With the cooperation of multiple nozzles 42, the water will be evenly sprayed on the top and bottom surfaces of the non-woven fabric 21. At the same time, when the rotating drum 3 continues to rotate, when the water outlet pipes 4 that are in contact between the two rotating drums 3 separate, the pressure on the movable seat 43 will disappear, and the spring 44 will start to rebound, causing the movable seat 43 to extend out of the water outlet pipe 4. At this time, the water outlet 46 of the movable seat 43 will be misaligned with the nozzle 42. At this time, the water outlet 46 of the movable seat 43 can be sealed by the inner wall of the mounting groove 41, so as to stop the water in the rotating drum 3 from being sprayed out through the nozzle 42 on the water outlet pipe 4, thereby improving the water-saving effect of the device. By setting multiple water outlet pipes 4 on the rotating drum 3, an appropriate amount of water can be sprayed onto the non-woven fabric 21 in a cyclical and even manner to wet it.

[0029] In the embodiments of this utility model, please refer to Figure 3 A partition 12 is fixedly connected inside the outer shell 1. The partition 12 is located below the rotating cylinder 3 and has several holes.

[0030] It should be noted that the partition 12 can reduce the impact force generated when water droplets fall on the surface of the non-woven fabric 21 during the wetting process, and prevent water droplets from splashing onto the bottom surface of the non-woven fabric 21, which would affect the uniformity of wetting. When water falls on the partition 12, it will enter the water inside the outer casing 1 through the drain hole, improving the water recycling effect of the device and avoiding the problem of water waste.

[0031] The working principle of the wetting device for nonwoven fabric processing provided by this utility model is as follows:

[0032] First, place the outer casing 1 in the designated working position, then fill the outer casing 1 with an appropriate amount of clean water, and then power on the electrical components of the device; after that, it can be used.

[0033] When using this device, first, the non-woven fabric 21 is wound onto the take-up roller 2 on the side away from the fixed motor 22. Then, one end of the non-woven fabric 21 is passed through the inlet and outlet 11 and wound onto the take-up roller 2 on the side close to the fixed motor 22. Then, the fixed motor 22 is started, which drives the take-up roller 2 connected to it to rotate. At this time, during the rotation of the take-up roller 2, it can take up the non-woven fabric 21 on the other take-up roller 2, so that the part of the non-woven fabric 21 inside the outer shell 1 is always in a state of uniform speed movement, which is convenient for the subsequent uniform wetting of the non-woven fabric 21.

[0034] When wetting the nonwoven fabric 21, the rotary motor 57 is started, which drives the pulley A51 to rotate. The pulley A51, through the transmission belt 53, drives the pulley B52 and the gear A54 to rotate in the same direction and at the same speed. During this process, the gear A54 drives the gear B56, which meshes with it, to rotate in the opposite direction and at the same speed. At this time, through the cooperation of the gears A54 and B56, the two rotating drums 3 are driven to rotate in opposite directions. At this time, the water pump 61 is started, which delivers water from the outer shell 1 into the rotating drums 3 through the water supply pipe 62 and the connector 6, filling the rotating drums 3 with water. Then, when the rotating drums 3 rotate and the water outlet pipes 4 between the two rotating drums 3 are aligned, the two movable seats 43 press against each other through the nonwoven fabric 21, causing the movable seats 43 to retract into the mounting groove 41 and compress the spring 44. At this time, the water outlet hole 46 on the movable seat 43 will connect with the nozzle 4. 2. When the rotating drum 3 is connected, the water inside will be sprayed out through the water inlet 45, water outlet 46 and nozzle 42. Through the cooperation of multiple nozzles 42, the water is evenly sprayed on the top and bottom surfaces of the nonwoven fabric 21. At the same time, when the rotating drum 3 continues to rotate, when the water outlet pipes 4 that are in contact between the two rotating drums 3 separate, the pressure on the movable seat 43 disappears, the spring 44 begins to rebound, and the movable seat 43 extends out of the water outlet pipe 4. At this time, the water outlet 46 of the movable seat 43 will be misaligned with the nozzle 42. At this time, the water outlet 46 of the movable seat 43 can be sealed by the inner wall of the mounting groove 41, so as to stop the water in the rotating drum 3 from being sprayed out through the nozzle 42 on the water outlet pipe 4, thereby improving the water-saving effect of the device. By setting multiple water outlet pipes 4 on the rotating drum 3, an appropriate amount of water can be sprayed onto the nonwoven fabric 21 in a cyclical and even manner to wet it.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
