Description

Technical Field

[0001] The utility model relates to the technical field of cotton sheet processing, in particular to a device for puncturing cotton sheets. Background Art

[0002] Thermal insulation cotton is a chemical fiber material with the characteristics of being light, thin, soft, warm, breathable, and moisture-permeable. During the production of thermal insulation cotton, a needle loom is required to increase the cohesion between fibers. The fiber web is repeatedly punctured with a needle with a triangular or other shaped cross-section and barbed hooks on the edges. The fiber web produced by the cross-web or air-web machine is very fluffy when fed into the needle loom. It only generates a certain strength due to the cohesion between the fibers, but the strength is very poor. When multiple needles penetrate the fiber web, the barbed hooks on the needles will drive the fibers on the surface and subsurface of the fiber web from the plane direction of the fiber web to the vertical direction of the fiber web, causing the fibers to shift up and down. The fibers that shift up and down squeeze the fiber web to a certain extent, causing the fibers in the fiber web to move closer together and be compressed.

[0003] However, the existing non-woven cotton needle punching machine still has some shortcomings during use. The existing non-woven cotton needle punching machine is in use:

[0004] 1. During the needling process of the thermal insulation cotton, the connection between the thermal insulation cotton is very loose, which makes it easy for the needle to take away some of the cotton wool, affecting the production of the entire thermal insulation cotton;

[0005] 2. There is an upper limit to the needle density in a unit. A high density will cause fiber breakage and the possibility of needle breakage.

[0006] 3. The needles are easily damaged under high-intensity work, but the existing non-woven cotton needle looms are not convenient for users to replace the needles or to regularly maintain and service the needles, causing a certain degree of inconvenience to users. Utility Model Content

[0038] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] like Figures 1 to 4 As shown, a device for puncturing a cotton sheet includes a frame 100 and a controller. The frame 100 is provided with a humidifying chamber 110, a high-pressure chamber 120 and a drying chamber 130.

[0041] The frame 100 has a first conveyor mesh belt 121, a second conveyor mesh belt 122 and a third conveyor mesh belt 131 arranged from top to bottom. Each conveyor mesh belt includes two drive rollers rotatably fixed to the frame 100, one of which is connected to a motor driving its rotation, and a mesh belt is connected between the two drive rollers.

[0042] The humidifying chamber 110 is provided with a climbing grid drive belt 111, the lower end of which is connected to the cotton feeding port 101 of the device. The humidifying chamber 110 is connected to a humidity control system capable of regulating the internal humidity. The bottom of the humidifying chamber 110 is provided with a first drainage system for draining excess water out of the humidifying chamber 110.

[0043] An upper atomizing plate 112 is provided above the grid transmission belt 111 and is parallel thereto. A lower atomizing plate 113 is provided below the grid transmission belt 111 . The middle portion of the lower atomizing plate 113 is bent downward. The first drainage system includes a first drainage pipe connected to the bottom of the lower atomizing plate 113 .

[0044] The high-pressure chamber 120 has a first conveyor mesh belt 121 with horizontal transmission. The conveying direction of the first conveyor mesh belt 121 is backward, and the front end of the first conveyor mesh belt 121 is connected with the end of the grid transmission belt 111. Specifically, the transmission roller at the rear end of the grid transmission belt 111 and the transmission roller at the front end of the first conveyor mesh belt 121 are staggered left and right, so that the front end of the first conveyor mesh belt 121 is overlapped with the end of the grid transmission belt 111, so that the cotton sheet can be conveyed backward to the first conveyor mesh belt 121 through the grid transmission belt 111.

[0045] A second horizontally driven conveyor belt 122 is provided below the first conveyor mesh belt 121. The conveying direction of the second conveyor mesh belt 122 is forward, and the front end of the second conveyor mesh belt 122 is vertically connected to the end of the first conveyor mesh belt 121. Specifically, the drive rollers at the rear end of the first conveyor mesh belt 121 and the drive rollers at the front end of the second conveyor mesh belt 122 are arranged alternately left and right, so that the rear end of the first conveyor mesh belt 121 overlaps the front end of the second conveyor mesh belt 122, allowing the cotton sheet to be conveyed backwards via the first conveyor mesh belt 121 to the second conveyor mesh belt 122. Since the conveying directions of the first conveyor mesh belt 121 and the second conveyor mesh belt 122 are opposite, the cotton sheet is facing up on the first conveyor mesh belt 121 with side A facing up, and facing up on the second conveyor mesh belt 122 with side B facing up.

[0046] There is a high-pressure box 123 above the first conveyor mesh belt 121 and above the second conveyor mesh belt 122. The width of the high-pressure box 123 is not less than the width of the corresponding conveyor mesh belt. A plurality of high-pressure air spray holes are provided on the bottom surface of the high-pressure box 123. The height of the high-pressure box 123 is about 10 mm, the length is about 4 meters, and the width is slightly larger than the width of the cotton sheet, generally 4.5 meters. On the side of the high-pressure box 123 facing the cotton sheet, there are high-pressure air spray holes with a diameter of 1 mm and a spacing of 4×4 mm.

[0047] Both high-pressure boxes 123 are connected to a high-pressure air supply system, which consists of a 75-kilowatt worm air compressor and a 20MPa air storage tank. The 20MPa high-pressure air is transported from the air storage tank through the valve to the high-pressure box 123, so that the gas pressure ejected from the high-pressure box 123 toward the cotton sheet is not less than 20Mpa.

[0048] A second drainage system is provided at the lowest point of the bottom of the high-pressure chamber 120 . The second drainage system includes a second drainage pipe, which can drain excess water out of the high-pressure chamber 120 .

[0049] The drying chamber 130 includes a third conveyor mesh belt 131, located below the second conveyor mesh belt 122 and running horizontally. The third conveyor mesh belt 131 conveys backward, with its front end vertically connected to the rear end of the second conveyor mesh belt 122. Specifically, the drive rollers at the rear end of the second conveyor mesh belt 122 and the drive rollers at the front end of the third conveyor mesh belt 131 are arranged in a staggered manner, allowing the rear end of the second conveyor mesh belt 122 to overlap the front end of the third conveyor mesh belt 131, allowing cotton sheets to be transported backward from the second conveyor mesh belt 122 to the third conveyor mesh belt 131. The rear end of the third conveyor mesh belt 131 connects to the cotton outlet of the device, allowing cotton sheets to be transported out of the drying chamber 130.

[0050] The drying chamber 130 is provided with a high-temperature baking assembly 132 for baking the cotton sheets on the third conveyor mesh belt 131. The high-temperature baking assembly 132 comprises two groups, one group of high-temperature baking assemblies 132 being located above the upper flat belt of the third conveyor mesh belt 131, and the other group of high-temperature baking assemblies 132 being located below the upper flat belt of the third conveyor mesh belt 131. The air outlet side of each group of high-temperature baking assemblies 132 is disposed toward the cotton sheets. The high-temperature baking assembly 132 comprises an ionizing blower that discharges air toward the third conveyor mesh belt 131, and a dry-burning finned electric heating tube is disposed on the air outlet side of the ionizing blower. After the dry-burning finned electric heating tube is energized and heated, the heat generated is blown toward the cotton sheets by the ionizing blower, and the cotton sheets are baked with high-temperature air. The high-temperature air can penetrate the cotton sheets, and the cotton sheets can be dried efficiently.

[0051] The controller controls the humidity control system, two high-pressure air supply systems, and the high-temperature baking assembly 132, enabling automated operation of the device. The 75-kW worm air compressor, 20 MPa air storage tank, and humidification unit are purchased as complete components.

[0052] The humidity control system includes a first atomizing humidifier 4, a second atomizing humidifier 5, and a third atomizing humidifier 6. The humidification devices are purchased as complete units. The humidity control system also includes a first humidity sensor 1, a second humidity sensor 2, and a third humidity sensor 3. The first humidity sensor 1 is located at the front end of the grid conveyor belt 111. The first atomizing humidifier 4 has its atomizing outlet located in the middle section of the grid conveyor belt 111. The second humidity sensor 2 is located at the rear end of the grid conveyor belt 111. The second atomizing humidifier 5 has its atomizing outlet located behind the second humidity sensor 2. The atomizing outlet of the third atomizing humidifier 6 is located at the rear end of the first conveyor mesh belt 121, between the upper and lower flat belts of the first conveyor mesh belt 121. The third humidity sensor 3 is located behind the third atomizing humidifier 6. The first, second, and third humidity sensors 1, 2, and 3 are connected to the signal input of the controller, while the first, second, and third atomizing humidifiers 4, 5, and 6 are connected to the control output of the controller.

[0053] The first humidity sensor 1 is used to detect the humidity of the cotton sheets entering the device, and adjust the humidification level of the first atomizing humidifier 4 according to the initial humidity of the cotton sheets; the second humidity sensor 2 is used to detect the humidity of the cotton sheets after pre-humidification by the first atomizing humidifier 4, so that the humidity of the cotton sheets after pre-humidification is not less than 80%. Once the humidity of the cotton sheets detected by the second humidity sensor 2 is lower than 80%, the controller controls the grid transmission belt 111, the first conveyor mesh belt 121, the second conveyor mesh belt 122 and the third conveyor mesh belt to stop or slow down synchronously, thereby increasing the time for the cotton sheets to be humidified at the first atomizing humidifier 4, until normal operation is restored after the set time, and the cotton sheets are conveyed backward.

[0054] The cotton sheets should be kept at a constant humidity within the high-pressure chamber 120. When the third humidity sensor 3 detects that the humidity of the cotton sheets is below 80%, the controller controls the grid drive belt 111, the first conveyor mesh belt 121, the second conveyor mesh belt 122, and the third conveyor mesh belt 131 to synchronously stop or reduce their speed. At this point, the atomizing humidifiers continue humidifying until a set time has passed, restarting to convey the cotton sheets backwards.

[0055] Two second humidity sensors 2 are arranged on either side of the width of the grid drive belt 111, ensuring more accurate detection of the cotton sheet's humidity. The corresponding first, second, and third atomizing humidifiers 4, 5, and 6 each have two atomizing pipes, with their outlets located on either side of the width. This ensures more uniform humidification of the cotton sheet.

[0056] The pre-humidification section uses an ultrasonic humidifier to initially moisten the cotton sheets entering the main unit, bringing them to the required humidity. Two high-accuracy humidity measurement probes are located in the pre-humidification area, ensuring even more precise humidity readings. After the pre-humidified cotton sheets are conveyed via a conveyor belt to the high-pressure, constant-humidity zone, 20 MPa of high-pressure air is delivered from a gas tank through a valve to a high-pressure tank 123. Under constant humidity, the high-pressure air flowing from tank 123 penetrates the cotton sheets. After exiting the first mesh conveyor belt 121, the cotton sheets flow into the second mesh conveyor belt 122. Simultaneously, the cotton sheets are flipped, facing backside up, and passed through the second high-pressure tank, where they undergo a secondary puncture. After this secondary puncture, the cotton sheets fall from the second mesh conveyor belt 122 onto the third mesh conveyor belt 131, carrying them to the high-temperature drying zone. The mesh conveyor belt 131 utilizes a high-temperature, reciprocating structure. The high-temperature drying unit utilizes a stainless steel heating tube heat circulation system to maintain internal temperature and air flow.

[0057] This device abandons the traditional acupuncture process and adopts high-pressure air as the medium. When the humidified cotton sheet passes through the high-pressure chamber 120, the high-pressure gas ejected from the high-pressure box 123 is used to puncture the cotton sheet. In addition, the special spatial layout of the first conveyor mesh belt 121 and the second conveyor mesh belt 122 is used to achieve double-sided puncture of the cotton sheet. The strong pressure causes the fibers on the surface of the cotton sheet to move deeper into the cotton sheet, and the fibers in the fiber web are entangled with each other, thereby increasing the tension of the cotton sheet. The cotton sheet is finally punctured by air high-pressure and treated at high temperature. The shaped cotton sheet changes its shape, so that the cotton fibers reach the ideal throw and the tension reaches the required standard. At the same time, because there is no strong intervention of physical needles, the fluffy feeling on the surface of the cotton sheet will not disappear.

[0058] The above are only preferred embodiments of the present invention. Any simple modification, deformation and equivalent replacement made by anyone to the present invention based on the content of the present invention shall fall within the protection scope of the present invention.
