Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration membrane production technology, and in particular to a surface treatment device for a support body for tubular ultrafiltration membrane production. Background Technology

[0002] Tubular ultrafiltration membranes are widely used in water treatment, food processing, and other fields. Their tubular support, as a core component, requires a smooth, flat inner surface to ensure a tight fit with subsequent filter media and guarantee filtration efficiency. Currently, tubular ultrafiltration membrane supports are mostly made of tubular metal or polymer structures. During the manufacturing process, burrs, flash, and other defects can easily remain on the inner surface. These defects can affect the installation accuracy of the filter media and even cause damage. Therefore, targeted treatment of the inner surface of the support is necessary.

[0003] Existing surface treatment methods for supports mainly involve manual hand-held grinding or single mechanical grinding. Manual grinding is inefficient, and the quality is greatly affected by the operator's experience, making it difficult to ensure consistency. Furthermore, the debris generated during grinding requires additional cleaning processes, resulting in poor overall continuity. This not only increases the workload but may also affect product quality due to debris residue. Therefore, a surface treatment device for supports in the production of tubular ultrafiltration membranes is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface treatment device for a support body used in the production of tubular ultrafiltration membranes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A surface treatment device for a support body for producing tubular ultrafiltration membranes includes a conveyor, a plurality of evenly distributed support seats fixedly installed on the outer surface of the conveyor belt for supporting workpieces, a side baffle fixedly connected to the top of the conveyor, a fixed frame fixedly connected between the side baffle and the conveyor, a cylinder fixedly connected to the top of the fixed frame, and an mounting bracket fixedly connected to one end of the piston rod of the cylinder. Two rotating tubes are rotatably connected to one side of the mounting bracket. A grinding disc and a brush disc are respectively fixed at one end of the two rotating tubes for treating the inner surface of the workpiece. The distance between the two rotating tubes is the same as the distance between two adjacent sets of support seats. The clamping mechanism is located below the fixed frame and is used to clamp the workpiece being processed.

[0006] As a further embodiment of this utility model, a guide rod is fixedly connected to one side of the mounting bracket, and the guide rod slides through the side of the mounting bracket.

[0007] As a further embodiment of this utility model, the clamping mechanism includes two sliding rods and an inclined surface. The sliding rods slide through the bottom of the fixed frame, and a pressure plate is fixedly connected between the bottoms of the sliding rods. The pressure plate moves downward and presses against the two workpieces being processed. Springs are sleeved around the circumference of each sliding rod, and the two ends of the springs abut against the top of the sliding rod and the surface of the fixed frame respectively through spring seats. The inclined surface is located at the end of the guide rod away from the mounting frame.

[0008] As a further embodiment of this utility model, the top of the pressure plate is provided with a clearance groove, and a roller is rotatably connected in the clearance groove. The roller is used in conjunction with the guide rod.

[0009] As a further embodiment of this utility model, a motor is fixedly connected to one side of the mounting bracket, and one end of the motor output shaft is driven by one of the rotating tubes through a synchronous pulley and synchronous belt, and the two rotating tubes are driven by a synchronous pulley and synchronous belt.

[0010] As a further embodiment of this utility model, a protective cover is fixed to one side of the mounting bracket by bolts, and the synchronous pulley and synchronous belt are both located inside the protective cover.

[0011] As a further embodiment of this utility model, a rotary joint is installed at the end of the rotating tube near the mounting bracket, and multiple through-holes are provided around the circumference of the rotating tube. The end of the rotating tube away from the rotary joint is open, and a negative pressure dust removal device is connected through the rotary joint to process the workpiece.

[0012] Working Principle: In this application, a servo motor controls a conveyor to intermittently transport the tubular support (workpiece) of the ultrafiltration membrane. Two rotary joints are connected to a negative pressure dust removal device. When the workpiece moves to the position corresponding to the rotating tube, the cylinder and motor start. The cylinder drives the mounting frame to approach the workpiece, so that the grinding disc is inserted into the workpiece. The grinding disc rotates under the drive of the motor, grinding the inner surface of the workpiece to remove burrs and improve its flatness, which facilitates the installation of filter materials. Another brush disc can clean the inner surface of the workpiece after grinding. The negative pressure filtration device (vacuum filter) extracts the debris or dust generated by grinding, improving product quality, avoiding manual cleaning, and improving the degree of automation of cleaning. When the mounting frame moves, it also drives the guide rod to move. The guide rod uses the inclined surface at its end to press the pressure plate downward, so that the pressure plate presses the workpiece and prevents the workpiece from moving.

[0013] Beneficial effects: In this utility model, the surface treatment device for the production support of tubular ultrafiltration membrane is used in combination with a grinding disc, a brush disc and a negative pressure dust removal structure. The motor drives the two to run synchronously. The grinding disc removes burrs while the brush disc cleans residual debris. The negative pressure equipment sucks away impurities in time through the air holes of the rotating tube. No manual cleaning is required afterward. This not only improves the inner surface precision of the workpiece, but also speeds up the processing pace and ensures a clean processing environment. In this utility model, the surface treatment device for the production support of tubular ultrafiltration membranes uses the cooperation of guide rod inclined surface, rollers and springs and pressure plates. When the cylinder drives the mounting frame to move down, the inclined surface squeezes the rollers and drives the pressure plate to automatically press the workpiece. After processing, the spring resets and releases the workpiece. No additional power control is required to hold the workpiece, ensuring that the workpiece is stable and does not shake during processing, and does not interfere with the intermittent conveying process of the conveyor.

[0016] 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.

[0017] In one embodiment: Refer to Figures 1-3A processing device includes: a conveyor 1, which is driven by a servo motor and can control the start and stop of the conveyor belt and the conveying distance to achieve intermittent conveying of workpieces (achieved through photoelectric sensors and PLC controllers, etc., which is existing technology). Multiple sets of evenly distributed support seats 2 are bolted to the outer surface of the conveyor belt of the conveyor 1. The top of each support seat has a groove adapted to the outer diameter of the workpiece; the workpiece is positioned by placing it in the groove. Each set of support seats 2 supports one workpiece, ensuring that the workpiece does not shift laterally or roll during conveying. Side baffles 3 are welded to the top of the conveyor 1 along the length of the conveyor belt.

[0018] In this invention, a fixed frame 4 is bolted to the side baffle 3 and the frame of the conveyor 1. The fixed frame 4 spans above the conveyor belt and has an overall "gate"-shaped structure, providing a mounting carrier for subsequent actuators. A cylinder 5 is bolted to the center of the top crossbeam of the fixed frame 4, and its end is bolted to the mounting frame 7. When the cylinder 5 is activated, it can directly drive the mounting frame 7 to move. A parallel guide rod 14 is also welded to one side of the mounting frame 7. The end of the guide rod 14 away from the mounting frame 7 slides through the side crossbeam of the fixed frame 4. The guide rod 14 is parallel to the piston rod of the cylinder 5. When the cylinder 5 drives the mounting frame 7 to move, the guide rod 14 can slide synchronously along the through hole of the fixed frame 4, effectively preventing the mounting frame 7 from shaking or shifting during movement, ensuring the accuracy of subsequent grinding and cleaning operations.

[0019] In this invention, two through-hole rotating tubes 8 are rotatably connected to one side of the mounting frame 7 via bearings. The distance between the two tubes is the same as the distance between two adjacent sets of support seats 2, allowing the two rotating tubes 8 to simultaneously correspond to the workpieces on the two sets of support seats 2. A grinding disc 9 and a brush disc 10 are respectively fixed to the ends of the two rotating tubes 8 away from the mounting frame 7 via keys. The grinding disc 9 can be a nylon wire-drawing grinding disc, the diameter of which is adapted to the inner diameter of the workpiece, used for grinding the inner surface of the workpiece. The brush disc 10 is made of nylon brushes, the brush length of which is slightly larger than the inner diameter of the workpiece. The grinding disc 9 and the brush disc 10 can realize grinding and automated cleaning of grinding debris, providing convenience for the subsequent installation of filter materials. Together with the grinding, cleaning, and clamping structures, they form a coherent automated processing system.

[0020] This application can be used in the field of tubular ultrafiltration membrane production, or in other fields applicable to this application.

[0021] In another embodiment: Reference Figures 1-3 A surface treatment device for a support in the production of tubular ultrafiltration membranes is disclosed. This device is applied in the field of tubular ultrafiltration membrane production. The structure of this embodiment is basically the same as the aforementioned embodiments, except that: Specifically, a motor 12 is fixedly connected to one side of the mounting bracket 7 via a motor mount. The output shaft of the motor 12 and the end of one of the rotating tubes 8 are both fitted with synchronous pulleys, which are connected by a synchronous belt. Simultaneously, synchronous pulleys are also fitted to the ends of the two rotating tubes 8 near the mounting bracket 7, and transmission is also achieved via synchronous belts. This transmission method ensures that after the motor 12 starts, the two rotating tubes 8 drive the grinding disc 9 and the brush disc 10 to rotate synchronously at the same speed. A protective cover 6 is also bolted to one side of the mounting bracket 7. All synchronous pulleys and synchronous belts are covered inside the protective cover 6, preventing grinding debris from adhering to the synchronous pulleys and belts and affecting the transmission effect, and also preventing operators from accidentally touching rotating parts and causing safety hazards.

[0022] It should be noted that a clamping mechanism for holding workpieces is provided below the fixed frame 4. This mechanism includes two parallel slide rods 15, which slide vertically through the fixed frame 4. A pressure plate 16 is bolted to the bottom of the slide rods 15. The length of the pressure plate 16 matches the distance between the two rotating tubes 8, allowing it to cover two workpieces to be processed simultaneously. Springs 17 are fitted around the circumference of each slide rod 15. The two ends of the springs 17 abut against the surface of the bottom crossbeam of the fixed frame 4 via spring seats welded to the top of the slide rods 15. In its natural state, the springs 17 are in an extended state, lifting the pressure plate 16 upwards to maintain a certain distance between the pressure plate 16 and the workpiece, thus not affecting the conveying of the workpiece. The guide rod 14 has an inclined surface 18 at the end away from the mounting frame 7. A corresponding clearance groove is provided on the top of the pressure plate 16. A roller 19 is rotatably connected to the clearance groove via a pin. The outer circle of the roller 19 fits against the inclined surface 18 of the guide rod 14, forming a cooperative structure.

[0023] In this invention, each of the two rotating tubes 8 has a rotary joint 13 installed at one end near the mounting frame 7 via a threaded connection. The fixed end of the rotary joint 13 is used to connect to an external negative pressure dust removal device (such as a vacuum filter). Multiple through-holes 11 are evenly arranged on the circumferential wall of the rotating tube 8. The air holes 11 start from the open end of the rotating tube 8 away from the rotary joint 13 and are evenly distributed along the length of the rotating tube 8 to the position near the mounting frame 7. This allows the negative pressure dust removal device to form a negative pressure environment inside the rotating tube 8 through the rotary joint 13 after it is started. The debris and dust generated by grinding will enter the tube through the open end of the rotating tube 8 and then be quickly sucked into the negative pressure dust removal device through the air holes 11.

[0024] However, as is well known to those skilled in the art, the working principles and wiring methods of conveyor 1, cylinder 5 and motor 12 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0025] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
