Description

Technical Field

[0001] This utility model belongs to the field of filter element production technology, and in particular relates to a V-shaped filter element pressing device. Background Technology

[0002] A filter element is a precision filtration component. Based on different filtration needs and working principles, filter elements have evolved into various types. Through different structural designs and filter materials, they achieve fine filtration and ensure the normal operation of equipment.

[0003] Among them, V-shaped filter elements, with their unique three-dimensional folded structure, effectively increase the filtration area and achieve higher filtration efficiency within the same space, gradually becoming the first choice for filtration scenarios. However, in the manufacturing process of V-shaped filter elements, the process precision of the pressing process directly affects the structural stability and filtration performance of the filter element.

[0004] An analysis of existing V-shaped filter cartridge pressing equipment reveals several shortcomings. Specifically, the traditional positioning drive mechanism is prone to wear and tear after prolonged operation, leading to operational deviations and uneven pressing force. This results in paper core folding, deformation, and poor sealing. Furthermore, the equipment lacks efficient adjustment flexibility, requiring companies to frequently change production lines when producing multiple filter cartridge models, thus affecting the overall production efficiency of the filter cartridges.

[0005] Therefore, in order to meet the market's urgent demand for high-performance filter elements, industry practitioners have designed a V-shaped filter element pressing device. Utility Model Content

[0006] The purpose of this invention is to provide a V-shaped filter cartridge pressing device to solve the problems of easy wear of the positioning drive mechanism leading to operational deviation and uneven subsequent pressing force, paper core folding and deformation, and insufficient equipment adjustment flexibility making it difficult to adapt to the production of various filter cartridge models.

[0007] The present invention achieves the above objectives through the following technical solution: a V-shaped filter cartridge pressing device, comprising a device platform, two sets of positioning drive mechanisms are arranged opposite to each other on the upper surface of the device platform, each set of positioning drive mechanisms is provided with a positioning side plate, and a spacing adjustment mechanism is provided on the upper surface of the device platform located between the two sets of positioning side plates, and a paper core placement component is provided on the spacing adjustment mechanism.

[0008] The spacing adjustment mechanism includes two sets of adjustment support platforms arranged opposite to each other. Two sets of adjustment guide rods are fixedly arranged between the two sets of adjustment support platforms. A fixing block is fixedly arranged in the middle of each set of adjustment guide rods. A first support plate is arranged between the two sets of fixing blocks. Adjustment blocks are slidably arranged at both ends of each fixing block. A second support plate is arranged between the two sets of adjustment blocks located at the same end. A bidirectional threaded rod is rotatably arranged between the two sets of adjustment guide rods. An adjustment motor for driving the bidirectional threaded rod to rotate is arranged on the outer wall of one of the adjustment support platforms. Two sets of ball nut seats are arranged on the bidirectional threaded rod. The two sets of ball nut seats are respectively fixedly connected to the second support plate at the same end.

[0009] The paper core placement assembly is disposed between the first support plate and the adjacent second support plate. It includes two sets of first follower rods fixed to the first support plate and two sets of second follower rods fixed to the second support plate. The ends of the first follower rods and the second follower rods located on the same side are rotatably connected, and a positioning frame is provided between the two connecting ends. Several sets of positioning pieces are evenly distributed on the upper surface of the positioning frame.

[0010] Furthermore, the positioning drive mechanism includes two sets of positioning guide rails, each set of positioning guide rails is provided with a positioning slider, the positioning side plate is disposed between the two sets of positioning sliders, and a positioning adjustment cylinder is disposed between the two sets of positioning guide rails, the telescopic rod of the positioning adjustment cylinder is fixed to the positioning side plate.

[0011] Furthermore, the positioning and adjusting cylinder is fixed to the equipment platform by a cylinder mounting seat to ensure the horizontal movement accuracy of the telescopic rod during operation.

[0012] Furthermore, the telescopic rod end of the positioning adjustment cylinder is provided with a connector, which is fixed to the positioning side plate by bolts.

[0013] Furthermore, the bidirectional threaded rod is connected to the output shaft of the regulating motor via a coupling, which is a flexible coupling.

[0014] Furthermore, the top cross-section of the positioning piece is inverted "V" shaped.

[0015] Beneficial effects: This utility model has a reasonable design, simple and stable structure, and strong practicality, and has the following beneficial effects:

[0016] 1. Precise positioning and stable movement: This utility model uses a positioning drive mechanism composed of a positioning guide rail, a positioning slider and a positioning adjustment cylinder, in conjunction with a cylinder mounting seat to ensure the horizontal movement accuracy of the telescopic rod, thereby achieving stable and precise movement of the positioning side plate. This effectively avoids the problem of uneven clamping force caused by wear of the positioning mechanism in traditional equipment, ensuring that the paper core does not fold or deform during the clamping process, and improving the sealing performance and overall quality of the filter element.

[0017] 2. Flexible spacing adjustment: The cooperation between the bidirectional threaded rod and the ball nut seat in the spacing adjustment mechanism can realize the synchronous and symmetrical movement of the second support plate under the drive of the adjustment motor. It can flexibly adjust the spacing of the paper core placement components and adapt to the production of various types of V-shaped filter elements without changing the production line, which significantly improves the versatility and production efficiency of the equipment.

[0018] 3. Stable and reliable transmission structure: The bidirectional threaded rod is connected to the adjusting motor through a flexible coupling, which can effectively compensate for the relative displacement between the two shafts and reduce vibration and impact during transmission.

[0019] 4. Highly efficient filter element fixation: In the paper core placement assembly, the first follower rod and the second follower rod are rotatably connected to the positioning frame. The positioning plate with an inverted "V" shaped cross section on the positioning frame can fit tightly with the paper core of the V-shaped filter element. This not only achieves precise positioning of the paper core, but also effectively prevents the paper core from sliding during the pressing process, ensuring the paper core pressing effect of the filter element, thereby improving the subsequent performance of the filter element.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1:

[0026] Combination Figure 1-2 The V-shaped filter cartridge pressing device shown includes a device platform 1, which is integrally formed from high-strength steel and can effectively support subsequent components. Two sets of positioning drive mechanisms 2 are arranged opposite each other on the upper surface of the device platform 1. Each set of positioning drive mechanisms 2 is provided with a positioning side plate 3. The inner surface of the positioning side plate 3 is provided with an anti-slip rubber layer, which can effectively prevent the filter cartridge from sliding during the pressing process. A spacing adjustment mechanism 4 is provided on the upper surface of the device platform 1 between the two sets of positioning side plates 3. A paper core placement component 5 is provided on the spacing adjustment mechanism 4. The spacing adjustment mechanism 4 is used to adjust the spacing of the paper core placement component 5 to adapt to the placement of paper cores of V-shaped filter cartridges of different specifications.

[0027] The spacing adjustment mechanism 4 includes two sets of adjusting support platforms 401 arranged opposite each other. The adjusting support platforms 401 are firmly fixed to the equipment platform 1 by welding. Two sets of adjusting guide rods 402 are fixedly arranged between the two sets of adjusting support platforms 401. A fixing block 403 is fixedly arranged in the middle of each set of adjusting guide rods 402 to ensure that the position of the fixing block 403 on the adjusting guide rod 402 remains unchanged. A first support plate 404 is arranged between the two sets of fixing blocks 403. The first support plate 404 is connected to the fixing block 403 by bolts. Adjusting blocks 405 are slidably arranged at both ends of the fixing block 403. A linear bearing is installed inside the adjusting block 405. The linear bearing cooperates with the adjusting guide rod 402 to allow the adjusting block 405 to slide smoothly on the adjusting guide rod 402. A second support plate 406 is arranged between the two sets of adjusting blocks 405 located at the same end. The support plate 406 and the adjusting block 405 are fixedly connected by bolts. A bidirectional threaded rod 407 is rotatably arranged between the two sets of adjusting guide rods 402. The two ends of the bidirectional threaded rod 407 are respectively mounted on the adjusting support platform 401 through bearing seats. The bearing seats provide stable support and rotation conditions for the bidirectional threaded rod 407. An adjusting motor 408 for driving the bidirectional threaded rod 407 to rotate is arranged on the outer wall of one of the adjusting support platforms 401. Two sets of ball nut seats 409 are arranged on the bidirectional threaded rod 407. The two sets of ball nut seats 409 are fixedly connected to the second support plate 406 at the same end. When the bidirectional threaded rod 407 rotates, the two sets of ball nut seats 409 will move synchronously and in opposite directions along the axial direction of the bidirectional threaded rod 407, thereby driving the second support plate 406 to move, so as to adjust the spacing of the paper core placement assembly 5.

[0028] The paper core placement assembly 5 is disposed between the first support plate 404 and the adjacent second support plate 406. It includes two sets of first follower rods 501 fixed on the first support plate 404 and two sets of second follower rods 502 fixed on the second support plate 406. The ends of the first follower rods 501 and the second follower rods 502 located on the same side are rotatably connected by a rotating shaft, and a positioning frame 503 is provided between the two connected ends. Several sets of positioning pieces 504 are evenly distributed on the upper surface of the positioning frame 503. The positioning pieces 504 perfectly fit the contour of the V-shaped filter paper core fold, effectively preventing the filter paper core from sliding during the pressing process.

[0029] In this embodiment, the positioning drive mechanism 2 includes two sets of positioning guide rails 201. These two sets of positioning guide rails 201 are installed parallel and opposite to each other on the equipment platform 1. Their installation accuracy directly affects the subsequent movement accuracy of the positioning side plate 3. They have high surface hardness and good wear resistance, and can withstand long-term frequent sliding friction without significant wear, thus ensuring their long-term stability and accuracy. Each set of positioning guide rails 201 is provided with a positioning slider 202. The positioning slider 202 and the positioning guide rail 201 have a precise sliding fit relationship. The positioning side plate 3 is disposed between the two sets of positioning sliders 202. The positioning side plate 3 is firmly connected to the positioning slider 202 by bolts or other connecting parts, ensuring that they form a rigid whole. When the positioning slider 202 moves on the positioning guide rail 201, it can synchronously drive the positioning side plate 3 to move. The positioning side plate 3 is a component that directly contacts and positions and clamps the V-shaped filter element frame. Therefore, its movement accuracy and stability directly affect the production and pressing effect of the V-shaped filter element. A positioning adjustment cylinder 203 is set between the two sets of positioning guide rails 201. The telescopic rod of the positioning adjustment cylinder 203 is fixed on the positioning side plate 3. When the telescopic rod of the positioning adjustment cylinder 203 extends, it will push the positioning side plate 3 to move along the positioning guide rail 201 until the positioning side plate 3 reaches the preset position, which facilitates the preset position of the filter element frame and also facilitates the subsequent pressing work.

[0030] In this embodiment, the positioning adjustment cylinder 203 is fixed on the equipment platform 1 by the cylinder mounting seat, ensuring that the parallelism error between the cylinder axis and the horizontal plane of the equipment platform 1 is minimized, effectively avoiding the influence of lateral force caused by installation deviation, thereby ensuring the accurate displacement of the positioning side plate 3 during the filter element pressing process, and improving the overall positioning accuracy and operational stability of the equipment.

[0031] In this embodiment, a connector 204 is installed at the end of the telescopic rod of the positioning adjustment cylinder 203. The connector 204 is fixed to the positioning side plate 3 by bolts. The connector 204 can absorb the inertial impact force generated when the cylinder starts and stops, and can also compensate for minor installation errors, so that the telescopic power of the positioning adjustment cylinder 203 can be smoothly transmitted to the positioning side plate 3, further ensuring the stability and accuracy of the positioning side plate 3 during the movement process.

[0032] In this embodiment, the bidirectional threaded rod 407 and the output shaft of the regulating motor 408 are connected by an elastic coupling. During equipment operation, the elastic coupling can effectively compensate for radial and axial offsets and angular deviations caused by installation errors between the bidirectional threaded rod 407 and the output shaft of the regulating motor 408. At the same time, it absorbs vibrations and impacts generated during transmission, reducing operating noise. In addition, the elastic coupling also has an overload protection function. When the system torque exceeds the rated value, the elastic body deforms and slips, preventing the bidirectional threaded rod 407 or the regulating motor 408 from being damaged due to overload, thereby ensuring the stable operation and long-term reliability of the spacing adjustment mechanism 4.

[0033] In this embodiment, the top cross-section of the positioning piece 504 is inverted "V" shape, which can form the best fitting angle with the outline of the paper core fold of the V-shaped filter element, ensuring that the paper core of the filter element is subjected to uniform force during the pressing process. In addition, the tip of the inverted "V" shaped structure is rounded to avoid scratching the paper core surface of the filter element, ensuring structural stability and reliability under long-term high-frequency use.
