Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of microporous aeration tube processing, specifically to a pore-pressing machine for microporous aeration tube processing. Background Technology
[0002] In wastewater treatment, aquaculture, and other fields, microporous aeration pipes are key components for achieving efficient aeration. The uniformly distributed micropores on their surface disperse air into tiny bubbles, significantly improving gas-liquid contact efficiency and enhancing oxygen transfer. The processing quality of the micropores directly determines the aeration performance of the aeration pipe, with pore regularity and pipe integrity being the core indicators.
[0003] Currently, the processing of microporous aeration tubes mostly adopts the traditional punching process, which has significant drawbacks and easily leads to deformation of the aeration tube. During the punching process, the tool forms holes on the surface of the tube by rotating and cutting. Since aeration tubes are mostly made of elastic materials (such as rubber, PVC, etc.), the radial force during cutting will cause local tensile or compressive deformation of the tube. Especially in areas with dense punching, the cumulative deformation can lead to tube bending, uneven wall thickness, and even cracks.
[0004] Deformed aeration pipes exhibit problems such as disordered bubble distribution and increased local resistance during use, severely affecting aeration uniformity. Simultaneously, the structural strength of the deformed areas decreases, making them prone to breakage under water and air pressure, thus shortening their service life. Furthermore, correcting deformation requires additional shaping processes, extending the production cycle and increasing processing costs. Therefore, developing a dedicated perforation machine for microporous aeration pipe processing, specifically addressing the deformation issues caused by the perforation process, has become an urgent need to improve product quality and production efficiency. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a punching machine for processing microporous aeration pipes, which solves the technical problem in the prior art where the tool forms holes on the surface of the pipe body by rotating cutting, and since the aeration pipe is mostly made of elastic material, the radial force during cutting will cause local tensile or extrusion deformation of the pipe body.
[0006] According to one aspect, at least one embodiment of this disclosure provides a pore-pressing machine for processing microporous aeration tubes, comprising: A base and an outer frame, wherein the outer frame is fixed to the outside of the base; A positioning component is disposed on the base and the outer frame; The vertical cavity and the pressing assembly are provided, wherein the vertical cavity is formed inside the outer frame and the pressing assembly is disposed in the vertical cavity; The positioning component includes a circular hole, which is formed inside the side surface of the outer frame. An inner support tube is fitted inside the circular hole. Connecting brackets are provided on both sides of the inner support tube.

[0013] As a further technical solution, a support column is connected to the base via a vertical linear drive, and the support column is located directly below the inner support frame.
[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the positioning component solves the problem of easy deformation of elastic tubes during pressing by employing a coordinated design of internal support and pushing.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0023] like Figures 1-3 As shown, a pore-pressing machine for processing microporous aeration tubes is illustrated in one embodiment of this disclosure, comprising: The base 1 and the outer frame 2 are fixed to the outside of the base 1; Positioning component 4 is disposed on the base 1 and the outer frame 2; The vertical cavity 3 and the pressing assembly 5 are provided. The vertical cavity 3 is formed inside the outer frame 2, and the pressing assembly 5 is disposed in the vertical cavity 3. The positioning component 4 includes a circular hole 4-1, which is formed inside the side surface of the outer frame 2. An inner support tube 4-2 is fitted inside the circular hole 4-1. Connecting brackets 4-3 are provided on both sides of the inner support tube 4-2. The connecting brackets 4-3 are fixed to the outer surface of the outer frame 2 by bolts. A through hole 4-4 is formed on the surface of the inner support tube 4-2. Side cavities 4-5 are formed at both ends of the surface of the base 1. A pair of guide slide rods 4-6 are provided in each side cavity 4-5. A movable seat 4-7 is slidably connected to the guide slide rods 4-6. The movable seat 4-7 is connected to the side cavity 4-5 by a horizontal linear drive. Each movable seat 4-7 is provided with a push wheel 4-8 that is driven by electricity to rotate.
[0024] In some examples, a positioning component 4 is designed to achieve stable positioning of the aeration pipe. This component includes a horizontally oriented circular hole 4-1 on the side surface of the outer frame 2. An inner support tube 4-2 is fixed inside the circular hole 4-1 by a connecting bracket 4-3. The connecting bracket 4-3 is L-shaped, with one end welded to the outer wall of the inner support tube 4-2 and the other end connected to the outer surface of the outer frame 2 by bolts. A through hole 4-4 on the surface of the inner support tube 4-2 is axially oriented, corresponding to the hole to be processed, forming a positioning reference. Side cavities 4-5 are horizontally oriented at both ends of the surface of the base 1, with parallel guide slide rods 4-6 distributed inside. The bottom of the movable seat 4-7 is slidably connected to the guide slide rods 4-6, allowing it to move horizontally along the slide rods. A horizontal linear drive device (such as a cylinder) is installed at one end of the side cavity 4-5, with its output end connected to the side of the movable seat 4-7, driving the movable seat 4-7 to reciprocate. The push wheels 4-8 on the movable seat 4-7 are rotatably connected by the bracket and driven to rotate by the motor. The surface of the wheel is covered with a rubber layer. The two push wheels 4-8 are symmetrically distributed vertically to form a clamping space.
[0025] During operation, one end of the aeration pipe is fitted onto the inner support pipe 4-2. The inner support pipe 4-2 supports the aeration pipe from the inside, ensuring the pipe remains round and preventing deformation. The perforation 4-4 is aligned with the hole to be punched, providing precise positioning for punching. The horizontal linear drive device drives the moving seat 4-7 to move along the guide slide rod 4-6, while the pusher wheel 4-8 rotates under motor drive. The friction between the rubber layer and the surface of the aeration pipe clamps and pushes the pipe, causing the aeration pipe to move axially along the inner support pipe 4-2. During the pushing process, the guide slide rod 4-6 ensures the smooth movement of the moving seat 4-7, preventing deviation and ensuring uniform hole spacing. The supporting function of the inner support pipe 4-2 prevents the aeration pipe from collapsing due to force during punching, ensuring a regular hole shape. The rubber layer of the pusher wheel 4-8 increases friction, preventing slippage and preventing damage to the pipe. The precise control of the horizontal linear drive device allows for accurate adjustment of the feeding distance, ensuring consistent hole spacing. This component combines internal support fixation with push guidance to achieve stable positioning and precise feeding of the aeration pipe, providing a reliable guarantee for the pore pressing process.
[0026] like Figures 1-3As shown in the figure, the pressing assembly 5 in this embodiment includes a lifting seat 5-1. The lifting seat 5-1 is connected to the vertical cavity 3 by a vertical linear drive. A pair of side frames 5-2 are provided on the side end face of the lifting seat 5-1. A switching table 5-3 is rotatably connected to the side frame 5-2 through a rotating shaft. A plurality of punching rods 5-4 are fixedly connected around the surface of the switching table 5-3. A limit block 5-5 is provided at one end of the rotating shaft of the switching table 5-3. A plurality of positioning grooves 5-6 are opened around the outer surface of the limit block 5-5. The positioning grooves 5-6 correspond to the positions of the punching rods 5-4. An internal thread block 5-7 is provided on the side surface of one of the side frames 5-2. A stud 5-8 is connected to the internal thread block 5-7 through a threaded engagement. A positioning block 5-9 is provided at one end of the stud 5-8. The positioning block 5-9 is inserted into the positioning groove 5-6.
[0027] In some examples, a punching assembly 5 is designed to enable rapid switching and punching of different hole diameters. This assembly includes a lifting seat 5-1 in the vertical cavity 3, which is slidably connected to the guide rail via a slider and driven by a vertical linear drive device (such as a hydraulic cylinder) to lift vertically. Side frames 5-2 are vertically welded to the side end face of the lifting seat 5-1 and are symmetrically distributed. The switching platform 5-3 is rotatably connected between the two side frames 5-2 via a rotating shaft, with the shaft and the side frame 5-2 having a clearance fit. Punching rods 5-4 are evenly distributed around the circumference of the surface of the switching platform 5-3, with different rod diameters. They are fixed to the switching platform 5-3 by bolts to adapt to different hole diameter requirements. The limiting block 5-5 at one end of the rotating shaft of the switching table 5-3 is integrally formed with the shaft body. The positioning groove 5-6 on the outer surface corresponds one-to-one with the punching rod 5-4. The groove body has a triangular cross section. The internal thread block 5-7 on the side surface of one of the side frames 5-2 is welded and fixed. The stud 5-8 is screwed into the internal thread block 5-7 through threaded engagement. The positioning block 5-9 at one end is adapted to the shape of the positioning groove 5-6 and can be inserted into the positioning groove 5-6.
[0028] During operation, according to the required hole diameter, loosen the stud 5-8 to disengage the positioning block 5-9 from the positioning groove 5-6, rotate the switching table 5-3 to select the corresponding punching rod 5-4, align it with the hole to be punched, tighten the stud 5-8 to insert the positioning block 5-9 into the corresponding positioning groove 5-6, and lock the position of the switching table 5-3; the vertical linear drive device drives the lifting seat 5-1 to descend, causing the punching rod 5-4 to move downward, passing through the through hole 4-4 of the inner support tube 4-2 to punch the aeration pipe; after punching is completed, the lifting seat 5-1 rises and resets, completing one punching cycle. The lifting drive of the lifting seat 5-1 enables the punching action of the punching rod 5-4, and the guide rail ensures smooth lifting and improves punching accuracy. The rotating structure of the switching table 5-3 allows for quick switching between multiple punching rods 5-4 of different specifications without disassembly or replacement, improving work efficiency. The cooperation between the positioning groove 5-6 and the positioning block 5-9 ensures the accurate positioning of the punching rod 5-4 after switching, avoiding offset that could lead to hole position deviation. The threaded connection between the internal thread block 5-7 and the stud 5-8 provides reliable locking force, preventing the switching table 5-3 from rotating during punching. This component, through the combination of multiple specifications of punching rods 5-4 and precise positioning, enables rapid switching between different hole diameters and precise punching, adapting to the processing needs of various specifications of aeration pipes.
[0029] For example, such as Figure 3 As shown, one end of the inner support tube 4-2 has a tapered structure, and the other end of the inner support tube 4-2 has an open structure.
[0030] In some examples, the tapered structure at one end of the inner support tube 4-2 facilitates the insertion of the aeration tube, guiding the tube body to fit smoothly onto the inner support tube 4-2 and reducing installation resistance. The open structure at the other end facilitates waste removal. The combination of the tapered shape and the open shape not only facilitates material feeding but also ensures uniform support of the aeration tube by the inner support tube 4-2, ensuring the tube body remains stable and does not deform during pore pressing.
[0031] For example, such as Figure 1 As shown, the surface of the pusher wheel 4-8 is an arc-shaped concave structure, and the pusher wheel 4-8 is located on both sides of the inner support tube 4-2.
[0032] In some examples, the pusher wheel 4-8 has an arc-shaped concave surface located on both sides of the inner support tube 4-2. The arc-shaped concave surface fits against the outer surface of the aeration tube, increasing the contact area and friction to prevent slippage during pushing. The pusher wheels 4-8 distributed on both sides apply force from both sides of the tube body, making pushing more stable and preventing the tube body from deviating. Together with the support of the inner support tube 4-2, they ensure that the aeration tube moves in a straight line and ensures accurate hole positioning.
[0033] For example, such as Figure 1 As shown, a support column 6 is connected to the base 1 via a vertical linear drive, and the support column 6 is located directly below the inner support frame.
[0034] In some examples, the support column 6 on the base 1 is located directly below the inner support tube 4-2, and its height is adjustable via a vertical linear drive. When the support column 6 rises, it supports the inner support tube 4-2 from below, enhancing its stability and preventing the inner support tube 4-2 from bending under stress during the pressing process. Adjusting the support height according to the aeration tube specifications ensures precise support, improves the overall stability of the pressing process, and guarantees a regular hole shape.
[0035] In practical use: The aeration pipe is inserted through the tapered end of the inner support pipe 4-2, which supports the pipe body from the inside. The connecting bracket 4-3 fixes its position, and the through hole 4-4 is aligned with the hole to be pressed. The moving seat 4-7 moves along the guide slide rod 4-6, and the arc-shaped push wheel 4-8 clamps the aeration pipe from both sides. The electric drive rotates and pushes it to the pressing position. According to the hole diameter requirement, loosen the stud 5-8 to disengage the positioning block 5-9 from the positioning groove 5-6, rotate the switching table 5-3 to select the corresponding punching rod 5-4, and then tighten the stud 5-8 to lock it. The lifting seat 5-1 descends under vertical linear drive, and the punching rod 5-4 passes through the through hole 4-4 to complete the pressing. The support column 6 provides auxiliary support from below. After pressing, the lifting seat 5-1 resets, and the push wheel 4-8 continues to feed material to achieve continuous processing.
