Description

Technical Field

[0001] This utility model relates to the field of filter element manufacturing technology, and in particular to a composite filter element winding device. Background Technology

[0002] Composite filter cartridges primarily utilize a core filtration structure achieved by winding various types of wires with different structural properties onto a filter cartridge. Common filter layer structures, from the inside out, include high-precision meltblown PP cotton, a non-woven fabric or fiber layer carrying an activated carbon layer, and low-precision meltblown PP cotton. However, to maintain the stability of the filter cartridge structure, in some environments, additional wires with stronger structural properties are required to protect this core structure. During the winding process of these structural wires (such as PP plastic wires or glass fibers), the winding tension affects the tightness of the winding. Especially during the wire release and movement (where the structure constraining the wires needs to supply them along the radial direction of the filter cartridge), factors such as angle and position can cause uncontrollable differences in the tension and resistance of the wire supply structure. These variations ultimately affect product quality; therefore, effectively stabilizing the wire release tension to ensure product quality has become a pressing issue. Summary of the Invention

[0003] The purpose of this invention is to propose a composite filter element winding device for dynamically controlling the tension of the wire during the wire unwinding process. This helps to ensure reasonable winding tension during the winding process and thus guarantee the quality of the final product.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This utility model provides a composite filter element winding device, including a base and a positioning bracket disposed on the base. A filter element is rotatably disposed on the positioning bracket. The base is also provided with a driving device for driving the filter element to rotate, a first linear motion module, and a second linear motion module. A wire feeding assembly is installed at the movable end of the first linear motion module, and a wire pressing assembly is installed at the movable end of the second linear motion module. The wire pressing assembly includes a positioning plate fixedly disposed at the movable end of the second linear motion module. A groove is formed on the positioning plate in the vertical direction. Fixed pulleys are rotatably disposed on the positioning plate on both sides of the groove. An installation block is slidably disposed in the groove. A movable pulley is also installed on the installation block. The wire fed out by the wire feeding assembly passes through the top of the two fixed pulleys and the bottom of the movable pulley to form a connection with the surface of the filter element.

[0006] Furthermore, the mounting block is strip-shaped, the movable pulley is fixedly disposed above the mounting block, and a counterweight assembly is connected to the lower part of the mounting block.

[0007] Furthermore, the counterweight assembly includes a positioning disk and several counterweight blocks that are detachably mounted on top of the positioning disk.

[0008] Furthermore, the movable end of the second linear motion module is also fixedly provided with a support, and the support is provided with a weighing sensor for weighing the mounting block structure.

[0009] Furthermore, a light-shielding plate is fixedly installed on the mounting block, and at least two U-shaped photoelectric sensors are arranged in the vertical direction on the positioning plate. The light-shielding plate can trigger each of the U-shaped photoelectric sensors.

[0010] Furthermore, the movable end of the first linear motion module is fixedly provided with a mounting base, and the wire feeding assembly includes a wire feeding roller rotatably disposed on the mounting base. The mounting base is also provided with an adjustment mechanism for adjusting the rotational friction of the wire feeding roller.

[0011] Furthermore, a positioning rod is provided at the center of the mounting base, the wire feeding roller is sleeved on the outer periphery of the positioning rod, and an adjusting nut for pressing the wire feeding roller is threaded to the top of the positioning rod.

[0012] The beneficial effects of this utility model are as follows: By setting a movable pulley for thread feeding, this utility model utilizes the tension of the filter cylinder and the resistance provided by the thread feeding assembly, so that the thread is pulled up by the forces at both ends during the winding process. By keeping the movable pulley in a suspended state, the tension of the thread supply can be controlled, making the tension value related to the structural weight of the movable pulley assembly. In this way, the movable pulley can be kept in a suspended state by changing the rotation speed of the filter cylinder, thereby balancing the tension changes during winding by changing the rotation speed of the filter cylinder, which is conducive to reasonable tension control and ensuring the quality of the finished product.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 6 As shown in the figure, the present invention provides a composite filter winding device. In order to realize the structural function of the device, the device is configured to include a base 1 and a positioning bracket 2 disposed on the base 1, as follows. Figure 1 As shown, a filter cylinder 3 is rotatably mounted on the positioning bracket 2, and a driving device 4 for driving the filter cylinder 3 to rotate is also provided on the base 1, so that the filter cylinder 3 can be properly wound with the wire to be fixed. The positioning bracket 2 can preferably be configured to approach each other from both sides, with one side having a slide rail structure for guidance, thus facilitating the clamping and fixing of the filter cylinder 3 using the plate structure. Simultaneously, the base 1 is equipped with a first linear moving module 5 and a second linear moving module 7. The movable end of the first linear moving module 5 is equipped with a wire feeding assembly 6, and the movable end of the second linear moving module 7 is equipped with a wire pressing assembly. The orientation of the first linear moving module 5 and the second linear moving module 7 is preferably parallel to each other and parallel to the extension direction of the filter cylinder 3, resulting in optimal operational efficiency. To achieve adjustable control of the wire tension, the wire pressing assembly can be configured to include a positioning plate 8 fixedly mounted on the movable end of the second linear moving module 7, such as... Figure 2 As shown, a vertical groove is provided on the positioning plate 8, and fixed pulleys 9 are rotatably arranged on the positioning plate 8 on both sides of the groove, and mounting blocks 10 are slidably arranged in the groove (e.g., ...). Figure 4As shown), a movable pulley 13 is also installed on the mounting block 10. At this time, the wire released by the wire feeding assembly 6 passes through the top of the two fixed pulleys 9 and the bottom of the movable pulley 13 to form a connection with the surface of the filter cartridge 3. When the equipment is in operation, the filter cylinder 3 rotates to take in the wire from the wire feeding assembly 6. At this time, the wire that is dragged by the movable pulley 13 is subjected to tension on one side and resistance on the other. This tension can lift the movable pulley 13 in the vertical direction. By controlling the wire feeding process, the movable pulley 13 can be kept in a suspended state. Then, the tension of the wire on both fixed pulleys 9 is actually the same and related to the gravity of the structure where the movable pulley 13 is located. If the wire on both sides of the movable pulley 3 is kept in a vertical state, the actual tension will change to half of the gravity of the structure where the movable pulley 13 is located. However, since it is difficult for the movable pulley 13 to be suspended and stationary in the actual process, the actual tension will fluctuate slightly. However, compared with the situation in traditional operation where it is impossible to adjust in real time, it can be well controlled and improved. It can change the rotation speed of the filter cylinder 3 when the wire moves to stabilize the suspension position of the movable pulley 13 and thus stabilize the tension change. It has the advantage of real-time control, which is conducive to ensuring the quality of the final product. It should be noted that when the rotation speed of the filter cartridge 3 changes, at least the moving speed of the second linear moving module 7 needs to be changed accordingly to ensure that the wire is laid stably and orderly on the surface of the filter cartridge 3.

[0022] This utility model provides a composite filter winding device. To prevent the movable pulley 13 from bottoming out, the mounting block 10 can be configured in a strip shape. The movable pulley 13 is fixedly positioned above the mounting block 10, and a counterweight assembly is connected below the mounting block 10. This maintains a certain distance between the counterweight and the movable pulley 13, preventing bottoming out and affecting the rotation of the movable pulley 13 (the fixed pulley 9 and the movable pulley 13 are preferably configured to rotate). The counterweight assembly is used to control the weight according to the actual specifications of the product, thereby determining the required tension value. Considering that different filter structures may require different wires and different resistances, the counterweight assembly can include a positioning plate 15 and several counterweight blocks 16 that are movably and detachably mounted above the positioning plate 15. By changing the number of counterweight blocks 16, the mass of the overall structure containing the movable pulley 13 is changed, thereby changing the required wire tension in real time. To facilitate structural quality inspection and manual adjustment, a support can be fixedly installed at the movable end of the second linear motion module 7, such as... Figure 2 As shown, a weighing sensor 14 is provided on the support for weighing the structure of the mounting block 10, so that the counterweight can be read manually.

[0023] The composite filter winding device provided in this embodiment of the utility model requires reasonable control measures to minimize the displacement of the movable pulley 13 during operation, preventing it from becoming stuck upwards or falling below the groove. Here, a light-shielding plate 11 can be fixedly installed on the mounting block 10. Figure 4 As shown, the positioning plate 8 is configured with at least two U-shaped photoelectric sensors 12 arranged vertically, and a light-shielding plate 11 is configured to pass through the detection position of each U-shaped photoelectric sensor 12 to trigger it. The illustration shows two sensors, but considering that if the light-shielding plate 11 passes through one of them, the monitoring on the other side becomes very passive and prone to falling to the bottom or jamming, in actual operation, the number of sensors is preferably no less than four. During operation, the light-shielding plate 11 should be kept in the center position as much as possible, thus providing more data for convenient speed adjustment. In some other embodiments, linear displacement monitoring, such as a grating ruler structure, can also be used, which can provide more comprehensive data changes and is more conducive to real-time speed control, but the actual cost will also increase. The choice should be made according to the actual usage requirements.

[0024] This utility model provides a composite filter winding device. To facilitate operation and control of the device and prevent excessive or insufficient friction in the wire feeding assembly 6, a mounting base is fixedly installed at the movable end of the first linear motion module 5. The wire feeding assembly 6 includes a wire feeding roller rotatably mounted on the mounting base, and an adjustment mechanism is also provided on the mounting base to adjust the rotational friction of the wire feeding roller. In a preferred embodiment, a positioning rod is positioned at the center of the mounting base, and the wire feeding roller is sleeved on the outer periphery of the positioning rod. An adjusting nut for pressing the wire feeding roller is threaded to the top of the positioning rod. In this case, the positioning rod structure can support the wire feeding roller structure. At the same time, the adjusting nut provided by the positioning rod can control the sliding friction by cooperating with the elastic layer structure for pressing, making it easier to manually adjust and ensuring that the structure can operate normally.

[0025] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
