Description

Technical Field

[0001] This invention relates to the field of filter element winding, and more particularly to a shaking device and method and the filter element winding equipment formed therefrom. Background Technology

[0002] During the manufacturing process of the filter element, the processed membrane sheet needs to be wound onto a central shaft. During the winding process, the membrane sheet needs to be transferred from the unwinding module to the outer layer of the filter element for winding. During the transfer process, the tension of the membrane sheet will change at any time, and the tension cannot be adjusted in real time. If the tension is too small, the membrane sheet will wrinkle together. When it is transferred to the outermost layer of the filter element, the wrinkled membrane sheet will affect the performance of the filter element.

[0003] In existing technologies, wrinkles are eliminated by controlling the tension of the diaphragm. However, the tension of the diaphragm during transmission cannot be adjusted in real time, thus failing to effectively eliminate wrinkles. Summary of the Invention

[0004] This invention aims to at least partially solve one of the problems in related technologies. Therefore, the object of this invention is to provide a shaking device that uses the reciprocating movement of a shaking rod to shake the membrane sheet about to be wound onto the outer layer of a filter element. The shaking process can eliminate membrane wrinkles, ensuring that the membrane sheet is wound in a relaxed state on the outermost layer of the filter element, effectively ensuring the winding quality of the filter element.

[0009] Furthermore, sliders are provided at both ends of the shaking link, and a shaking guide rail is provided in the fixed bracket. The sliders are located in the guide rail and can move along the guide rail. The movement direction of the sliders is the same as the movement direction of the shaking rod.

[0010] Furthermore, the membrane rises vertically to the top of the filter element during the winding process and is wound around the outer layer of the filter element; the shaking rod moves in a horizontal direction.

[0027] Please see the appendix Figure 1-2A shaking device is used to shake the membrane 11 during the filter element winding process; it includes: a fixed bracket and a shaking assembly, the shaking assembly being located in the fixed bracket; it includes a shaking motor 4 and a shaking rod 5, the shaking motor 4 driving the shaking rod 5 to reciprocate, and the direction of movement of the shaking rod 5 being perpendicular to the transmission direction of the membrane 11.

[0028] The shaking device of this application is set at the position before the membrane 11 reaches the winding device; the reciprocating movement of the shaking rod 5 is used to shake the membrane 11 that is about to be wound on the outer layer of the filter element, and the movement direction of the shaking rod 5 is perpendicular to the transmission direction of the membrane 11. The shaking process can eliminate the wrinkles of the membrane 11, ensuring that the membrane 11 can be wound on the outermost layer of the filter element in a relaxed state, effectively ensuring the winding quality of the filter element.

[0029] To better achieve the shaking, the output end of the shaking motor 4 in this application is connected to one end of the shaking linkage 3, and the other end of the shaking linkage 3 is connected to the shaking rod 5. The length of the shaking rod 5 can be slightly larger than the width of the diaphragm 11 to ensure that the shaking rod 5 can fully contact the diaphragm 11.

[0030] Given that the diaphragm 11 has a certain width, to ensure that the shaking rod 5 maintains the same distance from the diaphragm 11 at all points during the shaking process, a shaking connecting rod 3 can be set to connect the shaking motor and the shaking rod 5. The output end of the shaking motor 4 is connected to one end of the shaking connecting rod 3, and the other end of the shaking connecting rod 3 is connected to the shaking rod 5. Slider blocks are set at both ends of the shaking connecting rod 3, and a shaking guide rail 2 is set in the fixed bracket. The sliders are located in the guide rail and can move along the guide rail. The direction of movement of the sliders is the same as the direction of movement of the shaking rod 5.

[0031] In this application, the moving direction of the slider and the moving direction of the shaking rod 5 are both perpendicular to the transmission direction of the diaphragm 11, ensuring that the shaking rod 5 is in frontal contact with the diaphragm 11 and shakes it during the transmission of the diaphragm 11.

[0032] In practical applications, the membrane 11 rises vertically to the top of the filter element during the winding process and is wound around the outer layer of the filter element. That is, after exiting the unwinding module, the membrane 11 needs to be transported to the very top of the filter element and then wound around the outside of the filter element. The center of the filter element is the central axis. During the rotation of the central axis, the membrane 11 is wound around the central axis to form the filter element. The diameter of the filter element gradually increases from the initial diameter of the central axis until winding is complete. All membranes 11 originate from the unwinding module, are transported vertically upwards to the very top of the filter element, and then wound. Here, the very top of the filter element refers to the top of the filter element that is not yet fully formed during winding. Once the filter element is wound to a specific diameter, the membrane 11 is cut off, and winding stops. Because the membrane 11 is transported vertically before reaching the very top of the filter element, the reciprocating movement of the vibrating rod 5 is horizontal.

[0033] As mentioned above, since the diameter of the filter element gradually increases during winding, the shaking device in this application needs to be located at the position where the membrane 11 contacts the filter element. That is, before the membrane 11 is wound to the outer layer of the filter element, the later the shaking occurs, the better. This is because shaking the membrane 11 that is about to be wound can effectively prevent the membrane 11, which contains wrinkles, from being wound. Therefore, as the diameter of the filter element changes, the position of the shaking device also needs to change accordingly. As the diameter of the filter element increases, the shaking device needs to continuously descend until it no longer coincides with the filter element in the horizontal direction. At this point, the position of the shaking device is the closest to the winding of the membrane 11 without affecting the winding.

[0034] In order to achieve effective adjustment of the height of the shaking device, this application also includes a lifting assembly, which drives the fixed bracket to move parallel to the transmission direction of the diaphragm 11.

[0035] The lifting assembly includes a lifting motor 8 and a lifting module 7 located below the fixed support. The output end of the lifting motor 8 is connected to the bottom of the fixed support through the lifting module 7. A lifting guide rail 1 is provided on the side of the fixed support, and the fixed support moves along the lifting guide rail 1 under the drive of the lifting motor 8. The lifting motor 8 can be fixed in a specific position, and the drive of the lifting motor 8 can drive the lifting module 7 and the entire fixed support to move vertically. As the diameter of the filter element increases, the lifting motor 8 drives the fixed support to descend until the shaking rod 5 is located below the bottom of the outermost layer of the filter element, ensuring that the shaking process does not interfere with the film winding process. At the same time, the shaking of the membrane 11 occurs as close as possible to the winding position.

[0036] This application also provides a fixing seat 6 on the side of the fixing bracket for fixing the shaking device after the shaking operation stops.

[0037] The reciprocating frequency and shaking force of the shaking rod 5 in this application can be designed according to the specific process. For example, the reciprocating frequency of the shaking rod 5 can be set to once every 1-2 seconds, as long as it can achieve the function of eliminating wrinkles on the diaphragm 11.

[0038] The shaking method provided in this application occurs during the process of winding the diaphragm 11 to form a filter element. When the diaphragm 11 is wound around the outside of the filter element, it first rises vertically to the top of the filter element and is wound around the outermost layer of the filter element. The filter element is formed by winding the diaphragm 11 around a central shaft. The shaking method of this application includes the following steps:

[0039] After the diaphragm 11 is output from the unwinding unit, it rises vertically to the top of the central shaft and is wound around the rotating central shaft;

[0040] The lifting motor 8 first rises to the highest position, because the filter element diameter is the smallest at this time. It can be raised to the position below the central tube to ensure that the winding process is not affected, and it can also shake the membrane 11 that is about to be transferred to the central shaft.

[0041] The vibrating motor 4 drives the vibrating rod 5 to vibrate the diaphragm 11 at a specific frequency, eliminating wrinkles on the diaphragm 11. During the subsequent descent of the fixed support, the vibrating frequency of the vibrating rod 5 can remain constant.

[0042] As the diameter of the filter element increases, the lifting motor 8 drives the fixed bracket to move down, ensuring that the position of the shaking rod 5 is below the bottom of the outermost layer of the filter element, ensuring that the winding process is not affected, and also shaking the membrane 11 that is about to be transferred to the central shaft;

[0043] Continuously adjust the height of the fixed bracket until the filter element is wound.

[0044] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
