Description

Technical Field

[0001] This invention relates to the field of intake pipe straightening technology, and more particularly to an intake pipe straightening mechanism. Background Technology

[0002] High-temperature LP process inlet pipe, usually refers to the inlet pipe in the high-temperature low-pressure chemical vapor deposition process. It is a key component used in the semiconductor, photovoltaic and other fields to accurately transport reaction precursors in a high-temperature and low-pressure environment.

[0003] Existing technologies, such as the invention with publication number CN222391487U, disclose a high-temperature and oil-resistant turbocharger intake pipe. This patent employs an intake pipe body with a first heat insulation layer installed on its inner wall. The inner wall of the first heat insulation layer is fitted with a high-temperature and oil-resistant rubber layer, and a nylon rope is threaded through the interior of the rubber layer. A second heat insulation layer is installed on the outer surface of the intake pipe body, and a heat-dissipating metal mesh is installed on its outer surface. A through-hole is formed inside the intake pipe body, and a heat-conducting metal rod passes through the through-hole. A third heat insulation layer is installed on the outer surface of the heat-conducting metal rod. This high-temperature and oil-resistant turbocharger intake pipe, by incorporating the high-temperature and oil-resistant rubber layer, possesses excellent high-temperature and oil resistance, meeting the requirements for high-temperature and oil resistance of automotive turbocharger intake pipes under the China VI emission standard. Furthermore, it has low production costs, good ozone resistance, long service life, and is safer and more reliable.

[0004] The inventors discovered in daily use that the lifespan of the intake pipe in the current high-temperature LP process is 240 times / replacement. After replacement, the surface of the intake pipe is covered with crystals, which causes blockage of the intake hole. At the same time, the intake pipe is bent and deformed, and cannot be reused after cleaning, which increases the cost. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and to propose an intake pipe straightening mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intake pipe straightening mechanism, comprising two base plates and an adjustment structure. A frame plate is fixedly connected to the upper surface of the base plate. Several rollers are installed on the inner wall of the frame plate. A transmission shaft is installed inside the roller frame plate. Two adjustment structures are provided on the inner wall of the frame plate. Each adjustment structure includes two sliding grooves, both of which are formed on the frame plate. A mounting plate is slidably connected to the inner wall of the sliding groove. A rotating shaft is rotatably connected to one side of the two mounting plates that are close to each other. A limit wheel is fixedly connected to the arc surface of the rotating shaft. An auxiliary plate is fixedly connected to the upper end of the mounting plate. A screw is rotatably connected to the upper surface of the auxiliary plate. A connecting plate is threadedly connected to the arc surface of the upper end of the screw. Connecting plates are fixedly connected to both ends of the connecting plate. Two insert rods are slidably connected to the inner wall of the connecting plate. The insert rods are slidably connected to the frame plate.

[0007] This preferred solution allows for adjustment of the limit wheel's position when straightening the intake pipe. The auxiliary plate and mounting plate can be moved up and down along the slide groove by rotating the screw, thus adjusting the height of the limit wheel. Once the limit wheel height is determined, the insertion rod is inserted into the frame plate to fix the mounting plate, ensuring the limit wheel can stably limit and straighten the intake pipe. This effectively prevents the intake pipe from shifting or bending during traction, improving compatibility with different intake pipe specifications and the straightening effect.

[0008] Preferably, a connecting rod is fixedly connected to one side of the two insertion rods that are close to each other, and the connecting rod has a circular cross-section.

[0009] By adopting this preferred solution, the connecting rod can pull two insert rods simultaneously to move them, avoiding the need to pull the insert rods one by one.

[0010] Preferably, a slide rod is fixedly connected inside the slide groove, and the slide rod is slidably connected to the mounting plate.

[0011] By adopting this preferred solution, the sliding rod can limit the position of the mounting plate, preventing the auxiliary plate from shifting during adjustment of the mounting plate.

[0012] Preferably, a rotating plate is fixedly connected to the upper end of the screw, and the cross-section of the rotating plate is quincunx-shaped.

[0013] By adopting this preferred solution, the rotating plate can be directly rotated when the screw needs to be rotated, and the rotating plate drives the screw to rotate.

[0014] Preferably, a spring is fitted onto the arc surface of the insertion rod, and the two ends of the spring are fixedly connected to the insertion rod and the connecting plate, respectively.

[0015] This preferred solution achieves the following: when a plug needs to be inserted for fixation, pulling the plug causes the spring to stretch, then aligning the plug with the connecting plate and frame plate, and then releasing the plug spring to retract and insert the plug for fixation.

[0016] Preferably, the frame plate has an auxiliary structure on the side near the drive shaft. The auxiliary structure includes two slide rails, both of which are fixedly connected to the frame plate. A slider is slidably connected to the inner wall of the slide rail, and a fixing rod is fixedly connected to the upper surface of the slider. A servo motor is fixedly connected to the side of the two fixing rods that are close to each other. The output end of the servo motor is adapted to the drive shaft. A fixing plate is fixedly connected to the side of the two sliders that are far from each other. A lead screw is threadedly connected to the inner wall of the fixing plate, and the lead screw abuts against the slide rail.

[0017] This preferred solution achieves the following: when it is necessary to connect the servo motor and the drive shaft, the lead screw can be rotated to move within the fixed plate and gradually move away from the slide rail, thus removing the restriction on the position of the slider within the slide rail. Subsequently, the fixed rod is pushed to drive the slider to slide along the slide rail, precisely aligning the output end of the servo motor with the drive shaft. After the position adjustment is completed, the lead screw is rotated in the opposite direction to make it press against the slide rail again, thereby stabilizing and fixing the position of the servo motor. This enables rapid docking and fixing of the servo motor and the drive shaft, improving equipment assembly efficiency and operational stability.

[0018] Preferably, a limiting rod is fixedly connected inside the slide rail, and the limiting rod is slidably connected to the slider.

[0019] By adopting this preferred solution, the limiting rod can limit the slider, preventing the slider from deviating when sliding on the inner wall of the slide rail, thus improving the stability of the slider sliding.

[0020] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to one end of the lead screw near the slide rail.

[0021] By adopting this preferred solution, the anti-slip pad can increase the friction between the lead screw and the slide rail, thus preventing slippage when the slide rail and the lead screw are fixed together.

[0022] Preferably, both ends of the auxiliary plate are provided with cleaning structures. The cleaning structure includes a connecting frame, which is fixedly connected to the auxiliary plate. A connector is slidably connected to the inner wall of the connecting frame. An insert is slidably connected to both the connector and the inner wall of the connecting frame. A connecting block is fixedly connected to the upper end of the insert. A ring is fixedly connected to the end of the connector away from the connecting frame. A cleaning brush is fixedly connected to the inner wall of the ring.

[0023] By adopting this preferred solution, when it is necessary to clean the surface of the intake pipe, the connecting block is operated to drive the insert block to slide on the inner wall of the connecting frame and the connector, so as to realize the quick assembly and disassembly of the connector and the connecting frame. This facilitates the replacement or cleaning of the cleaning brush on the inner wall of the ring, ensuring that the cleaning brush can continuously and effectively remove dust, impurities and other contaminants from the surface of the intake pipe, and preventing the accumulation of impurities from affecting the normal use of the intake pipe or the accuracy of subsequent testing.

[0024] Preferably, both the connector and the inner wall of the connecting frame are fixedly connected with anti-slip sleeves, and the anti-slip sleeves are rubber sleeves.

[0025] By adopting this preferred solution, the anti-slip sleeve can increase the friction between the insert block and the connecting frame and the connector, thus preventing slippage during connection.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, by setting an adjustment structure, the adaptability and straightening effect of intake pipes of different specifications are achieved. Specifically, when it is necessary to straighten intake pipes of different diameters or heights, the operator can rotate the plum blossom-shaped rotating plate at the upper end of the screw, causing the screw to rotate within the connecting plate. Since the connecting plate is relatively fixed to the frame plate through the connecting plate, the rotation of the screw is converted into the up and down sliding of the auxiliary plate and the mounting plate along the inner wall of the slide groove, thereby driving the limit wheel on the rotating shaft to rise and fall synchronously. This achieves precise adjustment of the height of the limit wheel, significantly improving the adaptability of the equipment to intake pipes of different specifications and the reliability of the straightening operation.

[0027] 2. In this invention, by setting up an auxiliary structure, the purpose of quickly connecting and fixing the servo motor and the drive shaft can be easily achieved. Specifically, when assembling the equipment or replacing the servo motor, the operator only needs to rotate the lead screw on the fixing plate, so that the rubber anti-slip pad at the end of the lead screw gradually moves away from the surface of the slide rail. At this time, the sliding restriction of the slider within the slide rail is released. Subsequently, pushing the fixing rod drives the slider to slide smoothly along the slide rail. During this process, the limiting rod inside the slide rail can effectively prevent the slider from shifting, ensuring that the output end of the servo motor can be accurately aligned with the drive shaft. After the position is adjusted to the correct position, the lead screw is rotated in the opposite direction, so that the anti-slip pad tightly abuts against the slide rail again. The slider is stably fixed by friction, thereby quickly completing the connection and fixing of the servo motor and the drive shaft. This not only simplifies the assembly process but also ensures the stability of the equipment during operation and avoids transmission failures caused by loose connections.

[0028] 3. In this invention, the cleaning structure facilitates convenient cleaning of the intake pipe surface and makes it easy to replace or wash the cleaning brush. In operation, when cleaning the intake pipe surface is required, the cleaning brush is pulled along with the intake pipe and comes into contact with its surface. The brush bristles effectively remove dust, oil, debris, and other impurities adhering to the intake pipe surface, ensuring its cleanliness. When the cleaning brush needs to be replaced or cleaned after a period of use, the operator can grasp the connecting block and pull it upwards, causing the insert to slide out from the inner wall of the connecting frame and connector. At this point, the connection between the connector and the connecting frame is released, and the ring with the cleaning brush can be removed from the auxiliary plate for cleaning or replacement with a new cleaning brush. During installation, simply insert the connector into the connecting frame, align the insert with the holes on the connecting frame and the connector, and then push the connector to insert the insert. Under the action of the rubber anti-slip sleeve, the friction between the insert and the connecting frame and connector increases, which can effectively prevent the connection from loosening and ensure that the cleaning brush remains stable during operation, thereby continuously and effectively cleaning the surface of the air intake pipe and avoiding impurities from affecting the subsequent use of the air intake pipe or the accuracy of related testing work.

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0033] Example 1, such as Figure 1-8 As shown, the present invention provides an intake pipe straightening mechanism, including two base plates 1 and an adjustment structure 5. A frame plate 2 is fixedly connected to the upper surface of the base plate 1. Several rollers 4 are installed on the inner wall of the frame plate 2. A drive shaft 3 is installed inside the frame plate 2. Two adjustment structures 5 are provided on the inner wall of the frame plate 2. An auxiliary structure 6 is provided on the side of the frame plate 2 near the drive shaft 3. Cleaning structures 7 are provided at both ends of the auxiliary plate 507.

[0034] The following section will explain the specific settings and functions of its adjustment structure 5, auxiliary structure 6, and cleaning structure 7.

[0035] like Figure 2 Of Figure 4As shown, the adjustment structure 5 includes two sliding grooves 506, both of which are formed on the frame plate 2. A mounting plate 509 is slidably connected to the inner wall of each sliding groove 506. A rotating shaft 511 is rotatably connected to one side of the two mounting plates 509 that is close to each other. A limiting wheel 510 is fixedly connected to the arc surface of the rotating shaft 511. An auxiliary plate 507 is fixedly connected to the upper end of the mounting plate 509. A screw 502 is rotatably connected to the upper surface of the auxiliary plate 507. A connecting plate 503 is threadedly connected to the arc surface of the upper end of the screw 502. Connecting plates 504 are fixedly connected to both ends of the connecting plate 503. Two insert rods 505 are slidably connected to the inner wall of the connecting plate 504, and the insert rods 505 are slidably connected to the frame plate 2. When it is necessary to adjust the limiting wheel 510 to straighten the intake pipe, the auxiliary plate 507 and the mounting plate 509 can be slidably moved up and down along the sliding groove 506 by rotating the screw 502, thereby adjusting the height position of the limiting wheel 510. Once the height of the limiting wheel 510 is determined, the insert rod 505 is inserted into the frame plate 2 to fix the mounting plate 509, ensuring that the limiting wheel 510 can stably limit and straighten the intake pipe, effectively preventing the intake pipe from shifting or bending during traction. This improves the adaptability and straightening effect for intake pipes of different specifications. A connecting rod 512 is fixedly connected to the side of the two insert rods 505 that are close to each other. The connecting rod 512 has a circular cross-section. The connecting rod 512 can pull the two insert rods 505 simultaneously to move them, avoiding the need to pull the insert rods 505 one by one. A sliding rod 508 is fixedly connected inside the sliding groove 506, and the sliding rod 508 is slidably connected to the mounting plate 509. The sliding rod 508 can limit the mounting plate 509 to prevent it from shifting when the auxiliary plate 507 is adjusted to the mounting plate 509. A rotating plate 501 is fixedly connected to the upper end of the screw 502. The rotating plate 501 has a quincunx cross-section. When it is necessary to rotate the screw 502, the rotating plate 501 can be rotated directly. The rotating plate 501 drives the screw 502 to rotate. The arc surface of the insertion rod 505 is fitted with a spring, and the two ends of the spring are fixedly connected to the insertion rod 505 and the connecting plate 504, respectively. When it is necessary to insert the insertion rod 505 for fixation, pull the insertion rod 505 to stretch the spring, then align the insertion rod 505 with the connecting plate 504 and the frame plate 2, and then release the spring of the insertion rod 505 to retract it, causing the insertion rod 505 to be inserted for fixation.

[0036] like Figure 5 and Figure 6As shown, the auxiliary structure 6 includes two slide rails 61, both of which are fixedly connected to the frame plate 2. A slider 68 is slidably connected to the inner wall of the slide rail 61. A fixing rod 63 is fixedly connected to the upper surface of the slider 68. A servo motor 62 is fixedly connected to the side of the two fixing rods 63 that are close to each other. The output end of the servo motor 62 is adapted to the transmission shaft 3. A fixing plate 67 is fixedly connected to the side of the two sliders 68 that are far from each other. A lead screw 64 is threadedly connected to the inner wall of the fixing plate 67. The lead screw 64 abuts against the slide rail 61. When it is necessary to connect the servo motor 62 to the drive shaft 3, the lead screw 64 can be rotated to move it within the fixed plate 67 and gradually away from the slide rail 61, thus releasing the restriction on the position of the slider 68 within the slide rail 61. Then, the fixed rod 63 is pushed to drive the slider 68 to slide along the slide rail 61, precisely aligning the output end of the servo motor 62 with the drive shaft 3. After the position adjustment is complete, the lead screw 64 is rotated in the opposite direction to re-press against the slide rail 61, thereby stabilizing and fixing the position of the servo motor 62. This achieves rapid docking and fixing of the servo motor 62 and the drive shaft 3, improving equipment assembly efficiency and operational stability. A limit rod 66 is fixedly connected inside the slide rail 61, and the limit rod 66 is slidably connected to the slider 68. The limit rod 66 can limit the slider 68, preventing it from shifting when sliding on the inner wall of the slide rail 61, thus improving the stability of the slider 68's sliding. An anti-slip pad 65, which is a rubber pad, is fixedly connected to the end of the lead screw 64 near the slide rail 61. The anti-slip pad 65 can increase the friction between the lead screw 64 and the slide rail 61, and prevent the slide rail 61 from sliding when it is fixed in contact with the lead screw 64.

[0037] like Figure 7 and Figure 8 As shown, the cleaning structure 7 includes a connecting frame 71, which is fixedly connected to the auxiliary plate 507. A connector 72 is slidably connected to the inner wall of the connecting frame 71. An insert 77 is slidably connected to both the connector 72 and the inner wall of the connecting frame 71. A connecting block 75 is fixedly connected to the upper end of the insert 77. A ring 73 is fixedly connected to the end of the connector 72 away from the connecting frame 71. A cleaning brush 74 is fixedly connected to the inner wall of the ring 73. When it is necessary to clean the surface of the intake pipe, the insert 77 is slid along the inner walls of the connecting frame 71 and the connector 72 by operating the connecting block 75. This allows for quick disassembly and assembly of the connector 72 and the connecting frame 71, facilitating the replacement or cleaning of the cleaning brush 74 on the inner wall of the ring 73. This ensures that the cleaning brush 74 can continuously and effectively remove dust and impurities from the surface of the intake pipe, preventing the accumulation of impurities from affecting the normal use of the intake pipe or the accuracy of subsequent testing. Anti-slip sleeves 76, which are rubber sleeves, are fixedly connected to both the connector 72 and the inner wall of the connecting frame 71. The anti-slip sleeve 76 can increase the friction between the insert 77, the connecting frame 71, and the connector 72, preventing slippage during connection.

[0038] Its overall working principle is that when the limit wheel 510 needs to be adjusted to straighten the air intake pipe, the auxiliary plate 507 and the mounting plate 509 can be driven to slide up and down along the slide groove 506 by rotating the screw 502, thereby adjusting the height position of the limit wheel 510. Once the height of the limiting wheel 510 is determined, the insertion rod 505 is inserted into the frame plate 2 to fix the mounting plate 509, ensuring that the limiting wheel 510 can stably limit and straighten the intake pipe, effectively preventing the intake pipe from shifting or bending during traction. This improves the adaptability and straightening effect of intake pipes of different specifications. The connecting rod 512 can pull two insertion rods 505 simultaneously to move them, avoiding pulling each insertion rod 505 one by one. The sliding rod 508 can limit the mounting plate 509 to prevent the auxiliary plate 507 from shifting when adjusting the mounting plate 509. When it is necessary to rotate the screw 502, the rotating plate 501 can be rotated directly, and the rotating plate 501 drives the screw 502 to rotate. When it is necessary to insert the insertion rod 505 for fixation, the insertion rod 505 is pulled to stretch the spring, and then the insertion rod 505 is aligned with the connecting plate 504 and the frame plate 2. Then, the spring of the insertion rod 505 is released to retract and drive the insertion rod 505 to be inserted for fixation.

[0039] When it is necessary to connect the servo motor 62 to the drive shaft 3, the lead screw 64 can be rotated to move within the fixed plate 67 and gradually move away from the slide rail 61, thus releasing the restriction on the position of the slider 68 within the slide rail 61. Then, the fixed rod 63 is pushed to drive the slider 68 to slide along the slide rail 61, precisely aligning the output end of the servo motor 62 with the drive shaft 3. After the position adjustment is completed, the lead screw 64 is rotated in the opposite direction to re-press against the slide rail 61, thereby stabilizing and fixing the position of the servo motor 62. This achieves rapid docking and fixing of the servo motor 62 and the drive shaft 3, improving equipment assembly efficiency and operational stability. The limit rod 66 can limit the slider 68, preventing it from shifting when sliding on the inner wall of the slide rail 61, thus improving the stability of the slider 68's sliding. The anti-slip pad 65 can increase the friction between the lead screw 64 and the slide rail 61, preventing slippage when the slide rail 61 and the lead screw 64 are fixed together.

[0040] When the surface of the intake pipe needs to be cleaned, the connecting block 75 is operated to drive the insert 77 to slide on the inner wall of the connecting frame 71 and the connector 72, so as to realize the quick disassembly and assembly of the connector 72 and the connecting frame 71. This facilitates the replacement or cleaning of the cleaning brush 74 on the inner wall of the ring 73, ensuring that the cleaning brush 74 can continuously and effectively remove dust, impurities and other debris from the surface of the intake pipe, and avoid the accumulation of impurities affecting the normal use of the intake pipe or the accuracy of subsequent testing. The anti-slip sleeve 76 can increase the friction between the insert 77 and the connecting frame 71 and the connector 72, and prevent slippage during connection.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
