Description

Technical Field

[0001] The utility model relates to the technical field of filter element wrapping equipment, in particular to a non-woven fabric winding device for filter elements. Background Technique

[0002] In water purification components and various filtration processes, a carbon rod composed of activated carbon fibers is generally selected as the filter element. The activated carbon fibers have excellent adsorption properties and can effectively remove organic substances, particles, rust, residual chlorine, odor, etc. in the liquid. When in use, the filter element may drop carbon powder and flow out with the liquid. Therefore, the filter element is usually wrapped with a covering fabric such as non-woven fabric that plays a filtering role.

[0003] During the wrapping process of the existing filter element non-woven fabric, the degree of fit between the non-woven fabric and the filter element cannot be guaranteed. If there are gaps between the non-woven fabric and the filter element, carbon powder may enter the filtered water through these gaps, affecting the water quality. At the same time, the non-tight fit of the non-woven fabric may also cause premature wear or detachment of the non-woven fabric, thereby shortening the service life of the filter element.

[0025] In order to make the content of the present utility model easier to understand, the technical solutions of the present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings, but the present utility model is not limited thereto.

[0026] Please refer to Figure 1 and Figure 2 , the present utility model provides a technical solution: a non-woven fabric winding device for a filter element, including a base 1, a filter element support mechanism 2 and a non-woven fabric adsorption mechanism 3 are arranged above the base 1. The filter element support mechanism 2 includes a horizontally arranged filter element limit bracket 21 and two rollers 22 that rotate in the same direction. The non-woven fabric adsorption mechanism 3 includes an adsorption plate 31. A negative pressure chamber is opened at the bottom of the adsorption plate 31. The negative pressure chamber is hermetically connected to a vacuum tube, and the other end of the vacuum tube is connected to a vacuum pump. A plurality of adsorption holes 32 communicating with the negative pressure chamber are opened above the adsorption plate 31. The adsorption holes 32 communicate with the negative pressure chamber. The vacuum pump is used to extract the gas in the negative pressure chamber. When negative pressure is generated in the negative pressure chamber, the adsorption holes 32 will transfer the negative pressure to the surface of the adsorption plate 31.

[0027] As a further preference of this embodiment, the filter element limiting bracket 21 further includes a positioning post 215. The positioning post 215 is arranged on the vertical symmetry line of the two side rollers 22. A filter element is rotatably connected to the positioning post 215 coaxially. The filter element can be in contact with the two rollers 22 at the same time, and the two rollers 22 drive the filter element to rotate at a certain speed. One end of the non-woven fabric is heated and melted and fixed on the outer side of the filter element. The other end of the non-woven fabric is placed above the adsorption plate 31. Under the action of the rollers 22, the non-woven fabric moves along with the filter element, and a negative pressure chamber generates negative pressure. The non-woven fabric is closely attached to the adsorption plate 31 under the action of the negative pressure, preventing it from shifting or slipping during the winding process.

[0028] As a further preference of this embodiment, an air valve is further arranged on the vacuum tube to control the gas flow in the vacuum tube. By closing or opening the air valve, the non-woven fabric on the adsorption plate 31 can be quickly stopped from being adsorbed or released.

[0029] As a further preference of this embodiment, the output end of the motor 6 is connected to the roller 22, which can control the synchronous rotation of the two rollers 22 to ensure the uniform winding of the filter element.

[0030] As a further preference of this embodiment, a liftable hot pressing mechanism 4 is arranged above the filter element support mechanism 2. The hot pressing mechanism 4 includes a heating cylinder 41. The heat generated by the heating cylinder 41 can be used to hot press and fix the non-woven fabric and the filter element, so that the non-woven fabric is effectively pressed and closely combined with the filter element, improving the bonding strength between the non-woven fabric and the filter element and enhancing the overall structural stability of the filter element.

[0031] As a further preference of this embodiment, the temperature of the heating cylinder 41 can be precisely controlled to ensure that the non-woven fabric will not be damaged due to overheating, and at the same time ensure sufficient temperature to achieve effective bonding.

[0032] Combined with Figure 3 , an inverted L-shaped support frame 5 is further arranged above the base 1. The hot pressing mechanism 4 further includes a moving seat 42. A first telescopic cylinder 51 is fixedly arranged on the inverted L-shaped support frame 5. The telescopic end of the first telescopic cylinder 51 penetrates through the inverted L-shaped support frame 5 and is fixedly connected to the moving seat 42. The up and down movement of the heating cylinder 41 is realized through the first telescopic cylinder 51. A plurality of first limiting rods 43 are fixedly arranged above the moving seat 42. The plurality of first limiting rods 43 penetrate through the inverted L-shaped support frame 5 to limit the descending distance of the heating cylinder 41 according to the size of the filter element.

[0033] As a further preference of this embodiment, a liftable pressing plate 33 is arranged above one side of the adsorption plate 31 close to the filter element support mechanism 2. A second telescopic cylinder 35 is fixedly arranged on one side of the moving seat 42 close to the adsorption plate 31. The telescopic end of the second telescopic cylinder 35 is fixedly connected to the liftable pressing plate 33. The up and down movement of the liftable pressing plate 33 is realized through the second telescopic cylinder 35. When the non-woven fabric is placed on the adsorption plate 31, the liftable pressing plate 33 is moved downward to apply pressure on the upper side of the non-woven fabric. Through the frictional force between the liftable pressing plate 33, the adsorption plate 31 and the non-woven fabric, a traction force is generated on the non-woven fabric, ensuring the stability and fit degree of the non-woven fabric during the winding process, reducing the gap between the non-woven fabric and the filter element, and improving the filtering effect.

[0034] As a further preference of this embodiment, a plurality of second limiting rods 34 are arranged above the liftable pressing plate 33, and a plurality of limiting blocks 44 are arranged on the side of the moving seat 42. The second limiting rods 34 respectively pass through the corresponding limiting blocks 44. Through the combined use of the second limiting rods 34 and the limiting blocks 44, it is prevented that the liftable pressing plate 33 descends excessively, resulting in equipment failure. At the same time, the position of the liftable pressing plate 33 can be accurately controlled, ensuring the accurate alignment of the liftable pressing plate 33 during the lifting process, maintaining the flatness of the non-woven fabric, and ensuring that the liftable pressing plate 33 presses the non-woven fabric evenly.

[0035] As Figure 4 and Figure 5 As shown, the filter element limiting bracket 21 includes an I-shaped adjusting block 211 and a fixed housing 212. The fixed housing 212 is a cavity structure. A compression spring 213 is fixedly arranged at the inner bottom of the fixed housing 212. The other end of the compression spring 213 abuts against the bottom of the I-shaped adjusting block 211. A limiting column 216 is fixedly arranged at the bottom of the I-shaped adjusting block 211. The limiting column 216 is sleeved in the compression spring 213 to limit the descending distance of the I-shaped adjusting block 211. Limiting holes 214 are respectively opened on the front and rear sides of the fixed housing 212.

[0036] As can be seen from the above description, when the filter element is coaxially placed on the positioning column 215, under the self-weight of the filter element, the I-shaped adjusting block 211 will be driven to move downward, so that the outer side of the filter element can be in contact with the two side rollers 22 at the same time, making the equipment not limited by the filter element size. At the same time, the limiting column 216 limits the descending distance of the filter element.

[0037] As a further preference of this embodiment, the control panel 7 can be used to control and monitor the operation of the entire non-woven fabric winding device for the filter element. The control panel 7 includes a plurality of control buttons and a display screen, which can display the working state of the device in real time. At the same time, through the control panel 7, the rotation of the rollers 22 can be started or stopped, the actions of the first telescopic cylinder 51 and the second telescopic cylinder 35 can be controlled, and the temperature of the heating cylinder 41 and the pressure of the liftable pressing plate 33 can be adjusted.

[0038] Working principle of the utility model:

[0039] Place the filter element on the positioning post 215. Under the self-weight of the filter element, the compression spring 213 is compressed. Under the limiting action of the limiting hole 214, the I-shaped adjusting block 211 moves downward until it abuts against the two rollers 22 on the lower side. Place one end of the non-woven fabric on the filter element, and control the first telescopic cylinder 51 to lower the heating cylinder 41 to contact the non-woven fabric. Melt the non-woven fabric by controlling the temperature of the heating cylinder 41 and then paste it on the outer side of the filter element. Then control the temperature of the heating cylinder 41 and move it upward; drive the rollers 22 to rotate synchronously through the motor 6, so as to drive the filter element to rotate around the filter element limiting bracket 21 at a certain speed. The other end of the non-woven fabric is pressed tightly by the adsorption plate 31 and the liftable pressing plate 33 to prevent the non-woven fabric from loosening during the winding process, reduce the gap between the non-woven fabric and the filter element, and ensure the stability and adhesion of the non-woven fabric during the winding process. When the non-woven fabric is wound one or more circles, control the first telescopic cylinder 51 again to lower the heating cylinder 41 to heat and bond the end of the non-woven fabric together with the non-woven fabric wound below.

[0040] The above are only the embodiments of the utility model, and do not limit the patent scope of the utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the utility model.
