Description

Technical Field

[0001] This utility model relates to the technical field of tower tray component processing equipment, and in particular to an integrated machine for grinding and calibrating semi-finished tower tray components. Background Technology

[0002] Tower trays are core components of tower equipment in industries such as chemical and petrochemical. Their manufacturing precision and surface finish directly affect the efficiency of mass and heat transfer. In the production and manufacturing process of semi-finished tower tray components, grinding and calibration are key processes. Special grinding equipment with abrasive belts is usually required to treat the surface of the components to eliminate defects such as burrs and welds, and to ensure that their geometric dimensions and surface quality meet the design requirements.

[0003] In the existing technology, the grinding equipment used generally has some inherent shortcomings in operation. The tension of the abrasive belt is one of the key parameters that determines the grinding quality and efficiency. However, most existing equipment adopts manual adjustment or fixed tension. This adjustment method is not only cumbersome and inefficient, but also difficult to make precise adjustments according to the real-time wear of the abrasive belt and different workpiece requirements. It is easy to cause uneven or unstable tension, which in turn affects the uniformity and stability of the grinding effect, and even shortens the service life of the abrasive belt.

[0004] Meanwhile, high-speed grinding of metal or non-metal components inevitably generates a large amount of dust and debris. This debris not only disperses throughout the workshop environment, causing air pollution and posing a potential threat to the health of operators, but also adheres to the surfaces of equipment and workpieces, affecting machining accuracy and subsequent processes. Existing methods typically rely on separate dust collection equipment or manual cleaning. This separate approach often suffers from low collection efficiency and an inability to effectively control pollution at its source, resulting in an overall less clean and efficient processing flow.

[0005] Therefore, this utility model proposes an integrated machine for grinding and calibrating semi-finished tower trays and tower components to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an integrated grinding and calibration machine for semi-finished tower trays and tower components, aiming to improve the problems of inconvenient adjustment of grinding belt tension, low precision, low efficiency in collecting grinding debris, and environmental pollution in the existing integrated grinding and calibration machine for semi-finished tower trays and tower components.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a semi-finished tower tray and tower component grinding and calibration integrated machine, including a grinding and calibration integrated machine with a grinding belt; and an adjustment component and a collection component installed on the grinding and calibration integrated machine.

[0008] The adjustment assembly includes a motor, a worm gear, a worm wheel, a rotating shaft, and a rubber roller. The motor is driven by the worm gear, which meshes with the worm wheel. The worm wheel is coaxially and fixedly connected to the rotating shaft. The rubber roller is oscillating and its outer circumferential surface abuts against the surface of the abrasive belt. The rotation of the rotating shaft drives the rubber roller to oscillate, thereby adjusting the tension of the abrasive belt.

[0009] The collection assembly includes an absorption hood, a collection box, a suction fan, and a conveying pipe. The absorption hood, located near the abrasive belt grinding area, is connected to the collection box via the conveying pipe. The suction fan is used to generate negative pressure airflow at the absorption hood.

[0010] Preferably, the rotating shaft is connected to the connecting shaft via a connecting block and a connecting frame, and the rubber roller is sleeved on the connecting shaft.

[0011] Preferably, the adjustment assembly further includes two support cylinders spaced apart, and the two ends of the rotating shaft are rotatably connected to the two support cylinders.

[0012] Preferably, the adjustment assembly further includes a fixing plate, and the motor is fixed to the fixing plate.

[0013] Preferably, the collection box is equipped with a filter screen inside.

[0014] Preferably, the lower part of the collection box is provided with a retractable receiving box for collecting debris.

[0015] Preferably, the filter screen is horizontally disposed inside the collection box and located above the receiving box.

[0016] Preferably, the receiving box is equipped with a handle for pulling it out of the collection box.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting up an adjustment component that uses a motor-driven worm gear mechanism to precisely control the position of the rubber roller to swing and adjust the tension of the abrasive belt, the problem of the abrasive belt tension relying on manual adjustment, which is time-consuming, labor-intensive, and lacks precision in the prior art is solved. This achieves the technical effect of automatically and precisely adjusting the tension of the abrasive belt, thereby ensuring the stability of the grinding quality and improving the automation level of the equipment.

[0018] 2. In this utility model, by setting up a negative pressure collection system consisting of a suction fan, an absorption hood, a collection box, and a filter screen, the problem of grinding debris spreading and polluting the working environment, as well as the difficulty and inefficiency of cleaning, is solved in the prior art. It achieves the technical effect of efficiently collecting grinding debris at the source, separating dust from air, and purifying the working environment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-6 This utility model provides an embodiment of a semi-finished tower tray component grinding and calibration integrated machine, which aims to solve the structural defects of the prior art in the grinding process of tower tray components, such as inconvenience in adjusting the tension of the grinding belt and low efficiency in collecting grinding debris.

[0023] Specifically, it includes a grinding and calibration integrated machine 1, and an adjustment component 3 and a collection component 2 installed on the grinding and calibration integrated machine 1. The grinding and calibration integrated machine 1 serves as the working platform and installation base of the entire device. It is equipped with a grinding belt for performing grinding functions, which is used to perform surface grinding and calibration operations on the semi-finished tray components. The adjustment component 3 is used to adjust the tension of the grinding belt to ensure the stability and consistency of the grinding effect. The collection component 2 is used to efficiently collect the debris generated during the grinding process and keep the working environment clean.

[0024] The adjustment assembly 3 mainly consists of a motor 308, a worm gear 309, a worm wheel 310, a rotating shaft 304, a rubber roller 303, a connecting frame 301, a connecting shaft 302, a connecting block 306, a support cylinder 305, and a fixing plate 307. The motor 308 is securely mounted on the body of the grinding and calibration integrated machine 1 via the fixing plate 307, providing a power source. The output end of the motor 308 is driven and connected to the worm gear 309. The worm gear 309 meshes with the worm wheel 310. The worm wheel 310 is coaxially and fixedly connected to the rotating shaft 304. When the worm wheel 310 rotates, the rotating shaft 304 rotates accordingly. The two ends of the rotating shaft 304 are rotatably supported inside two spaced support cylinders 305, ensuring the stable rotation of the rotating shaft 304. The rotating shaft 304 is connected to the connecting shaft 302 via the connecting block 306 and the connecting frame 301. The rubber roller 303 is sleeved on the outer wall of the connecting shaft 302, and its outer circumferential surface is always in contact with the surface of the abrasive belt. When the rotating shaft 304 rotates, it will drive the connecting shaft 302 and the rubber roller 303 on it to swing around the rotating shaft 304 as the center through the above-mentioned connecting mechanism, thereby precisely adjusting the tension of the abrasive belt and keeping it within a suitable working range.

[0025] The collection assembly 2 mainly consists of an absorption hood 202, a conveying pipe 201, a collection box 203, a filter screen 205, a receiving box 204, a suction fan 206, and a handle 207. The absorption hood 202 is located near the abrasion area of ​​the abrasive belt to capture debris as soon as it is generated. The absorption hood 202 is connected to the collection box 203 through the conveying pipe 201. Debris is guided into the collection box 203 through the conveying pipe 201. The suction fan 206 generates a negative pressure airflow at the absorption hood 202 to create suction, thereby efficiently sucking the debris into the collection system. In the adjustment assembly 3, the motor 308 is bolted to the body of the grinding and calibration integrated machine 1 via a fixing plate 307. The output shaft of the motor 308 is driven by the worm gear 309. When the motor 308 starts, the worm gear 309 begins to rotate. The worm gear 309 meshes with the worm wheel 310. This worm gear transmission structure can achieve a large transmission ratio and a self-locking function, ensuring the stability of the adjustment position. The worm wheel 310 is coaxially fixed to the rotating shaft 304, so the rotation of the worm wheel 310 directly drives the rotating shaft 304 to rotate synchronously. The two ends of the rotating shaft 304 are rotatably supported inside two spaced support cylinders 305. The support cylinders 305 are firmly fixed to the body of the grinding and calibration integrated machine 1, providing a stable axis of rotation for the rotating shaft 304.

[0026] The rotating shaft 304 is fixedly connected to the connecting frame 301 via a connecting block 306, and the other end of the connecting frame 301 is rotatably connected to the connecting shaft 302. A rubber roller 303 is sleeved on the outer wall of the connecting shaft 302, and its outer circumferential surface is in close contact with the inner surface of the abrasive belt. When the motor 308 drives the rotating shaft 304 to rotate, the rotating shaft 304, through the connecting block 306 and the connecting frame 301, drives the connecting shaft 302 and the rubber roller 303 to swing around the axis of the rotating shaft 304. This swinging motion of the rubber roller 303 directly changes its relative position to the abrasive belt, thereby precisely adjusting the surface tension of the abrasive belt. This ensures that the abrasive belt maintains a suitable tension during the polishing process, preventing the abrasive belt from becoming too loose or too tight, thus guaranteeing the polishing quality and extending the service life of the abrasive belt. This adjustment method avoids the cumbersome and inaccurate nature of traditional manual adjustment, improving the ease of operation and intelligence of the equipment. The adjusting assembly 3 also includes two spaced-apart support cylinders 305. The two ends of the rotating shaft 304 are rotatably connected to the interiors of these two support cylinders 305. This arrangement ensures that the rotating shaft 304 maintains good coaxiality and stability during rotation, reducing wobbling and thus allowing the rubber roller 303 to more precisely adjust the tension of the abrasive belt.

[0027] To ensure the stable installation of the motor 308, the adjustment assembly 3 also includes a mounting plate 307. The motor 308 is fixedly connected to the mounting plate 307 with bolts, and the mounting plate 307 is firmly fixed to the body of the grinding and calibration integrated machine 1. This fixing method can effectively absorb the vibration during motor operation and improve the reliability of the entire adjustment assembly 3.

[0028] To ensure that debris can be efficiently and smoothly transported from the absorption hood 202 to the collection box 203, the collection assembly 2 also includes a conveying pipe 201. One end of the conveying pipe 201 is connected to the absorption hood 202, and the other end is connected to the collection box 203, providing a sealed conveying channel for the debris and preventing secondary pollution during the conveying process.

[0029] To achieve separation of debris from air, a filter 205 is installed inside the collection box 203. The filter 205 is horizontally positioned in the upper middle part of the collection box 203. When debris and airflow enter the collection box 203, the filter 205 can effectively intercept solid debris while allowing clean air to pass through.

[0030] To facilitate subsequent cleaning of the collected debris, a retractable receiving box 204 is provided at the bottom of the collection box 203. The receiving box 204 is located below the filter screen 205 and is used to receive and store the solid debris separated by the filter screen 205. This retractable design makes the debris cleaning process exceptionally simple and quick.

[0031] To facilitate the removal and insertion of the receiving box 204, a handle 207 is connected to the receiving box 204. Operators can easily pull the receiving box 204 out of the collection box 203 by pulling the handle 207 to dump and clean up the debris, greatly improving the maintenance efficiency of the equipment; Working principle: When the grinding and calibration integrated machine 1 needs to adjust the surface tension of its internal abrasive belt, the motor 308 in the adjustment component 3 is started first. The output end of the motor 308 drives the worm 309 to rotate. Since the worm 309 and the worm wheel 310 are meshed with each other, the rotation of the worm 309 will drive the worm wheel 310 to rotate. The worm gear 310 is coaxially and fixedly connected to the rotating shaft 304. Therefore, while the worm gear 310 rotates, it drives the rotating shaft 304 to rotate. The two ends of the rotating shaft 304 are rotatably supported between two support cylinders 305, ensuring the stability of rotation. While rotating, the rotating shaft 304 drives the connecting shaft 302 and the rubber roller 303 sleeved on the outer wall of the connecting shaft 302 to swing around the rotating shaft 304 as the center through the connecting block 306 and the connecting frame 301. Since the outer circumferential surface of the rubber roller 303 is always in close contact with the surface of the abrasive belt, its position swing directly changes the tension of the abrasive belt, thereby achieving precise adjustment of the surface tension of the abrasive belt. This ensures that the surface tension of the abrasive belt is kept within a suitable range, avoiding jumping or uneven wear during the grinding process, thus improving the grinding quality and the reliability of equipment operation. This worm gear structure driven by a motor solves the problems of inconvenient and inaccurate adjustment of abrasive belt tension in the prior art. During the grinding operation on the surface of the tray components, the grinding and calibration integrated machine 1 activates the suction fan 206 in the collection component 2. The suction fan 206 generates strong suction, creating a negative pressure airflow at the absorption hood 202 near the grinding area. Using this suction, the grinding debris is efficiently drawn into the absorption hood 202. The drawn-in debris is then transported to the inside of the collection box 203 via the conveying pipe 201. Inside the collection box 203, a horizontally arranged filter 205 separates the debris from the airflow. Smaller air molecules pass through the filter 205 and are discharged from the exhaust port of the suction fan 206, achieving air... The filter screen 205 intercepts larger solid debris, which then falls into the receiving box 204 located at the bottom of the collection box 203 due to gravity. This effectively collects the debris. When the equipment is finished or when the debris in the receiving box 204 reaches a certain amount, the operator can simply pull the handle 207 connected to the receiving box 204 to easily pull it out of the collection box 203. Then, the debris inside the receiving box 204 can be poured into a designated location for centralized processing. This process collects and cleans the debris generated from grinding the surface of the tray components, greatly improving the cleanliness of the working environment and the efficiency of cleaning.
