Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, and in particular to a rubber head cutting device for an ultrafiltration membrane assembly. Background Art

[0002] Ultrafiltration membranes are widely used in industry and have become one of the new chemical unit operations. They are widely used in separation, concentration, purification of biological products, pharmaceutical products and food industries, and are also used in terminal treatment devices in blood treatment, wastewater treatment and ultrapure water preparation. Existing ultrafiltration membrane components are mainly divided into two types: curtain type (also often called flat plate or plate and frame type) and cylindrical (sometimes called tubular or hollow fiber type).

[0003] The cylindrical ultrafiltration membrane assembly includes a filter cartridge with openings at both ends, a number of ultrafiltration membrane filaments filled in the filter cartridge, and two groups of rubber discs arranged in the filter cartridge. The filter cartridge is equipped with a water inlet pipe and a sewage discharge pipe. The ultrafiltration membrane filaments are hollow and covered with micropores on their outer wall. One of the rubber discs is flush with one end of the filter cartridge, and the other rubber disc protrudes from the other end of the filter cartridge. Both ends of all ultrafiltration membrane filaments are respectively arranged in the two groups of rubber discs. When the cylindrical ultrafiltration membrane assembly is needed, the part of the rubber disc protruding from the end of the filter cartridge needs to be cut off, and the end of the ultrafiltration membrane filament located in the rubber disc will also be cut off; then, sewage is introduced into the filter cartridge through the water inlet pipe. Because the two groups of rubber discs respectively close the two ends of the filter cartridge, the water body will pass through the micropores on the ultrafiltration membrane filaments and be discharged from the cut end of the ultrafiltration membrane filaments, and the impurities mixed in the water body will be blocked outside the ultrafiltration membrane filaments, thereby achieving the filtration of sewage.

[0004] The curtain-type ultrafiltration membrane assembly includes two square rubber discs, a number of ultrafiltration membrane filaments connected between the two square rubber discs, and an inlet pipe for introducing sewage to be treated and a drain pipe for discharging suspended matter and impurities that are not filtered by the membrane filaments. When the curtain-type ultrafiltration membrane assembly is needed, a part of the two square rubber discs needs to be cut off to fully expose the ends of the membrane filaments to facilitate liquid penetration and achieve sewage filtration.

[0005] After searching, the patent announcement number is: CN211073850U, a rubber head cutting machine for hollow fiber ultrafiltration membrane components, which includes a workbench, a mounting plate, a rough cutting device, a heating device and a fine cutting device, and a clamping device is provided on the mounting plate. Although the patent can expose the ends of the ultrafiltration membrane wires by removing part of the rubber disc through the cyclic lifting and lowering of the rough cutting device, the patent cannot effectively isolate the cutting space. When cutting, the operation of the saw blade will cause debris and dust to fly and spread, causing the working environment to be polluted by debris and dust. Workers inhale the air polluted by debris and dust for a long time, which will affect their health. Summary of the invention

The lifting and lowering of the lifting plates 92 can be guided by the cooperation of the sliding sleeves and the guide rods to ensure that the lifting and lowering of the lifting plates 92 are smoothly carried out. The lifting plates 92 are slidingly connected with lifting rods 93 at intervals from front to back. The shape of the lifting rods 93 is T-shaped, and a spring Ⅰ94 is sleeved on the lifting rod 93. The two ends of the spring Ⅰ94 are respectively connected to the lifting rod 93 and the lifting plates 92, and the lifting rods of the lower lifting plates 92 are connected between the lower part of the lifting rod 93 of the upper lifting plate 92 and the lifting rod of the lower lifting plate 92.

[0035] See also Figure 6-Figure 9The fixture 8 includes a mounting frame 81 connected to the rear side of the top of the support plate 7, an electric push rod Ⅰ82 is installed on the upper part of the mounting frame 81, a movable frame 83 is connected to the telescopic rod of the electric push rod Ⅰ82, and the movable frame 83 is connected to two front and rear guide rods, and the guide rod is slidably connected to the mounting frame 81 to guide the lifting of the movable frame 83 to ensure that the movable frame 83 is lifted and lowered smoothly, an electric push rod Ⅱ84 is installed on the upper part of the movable frame 83, and a connecting block is connected to the telescopic rod of the electric push rod Ⅱ84 85, two front and rear L-shaped clamping plates 86 are hinged on the connecting block 85, and a slot 87 is formed on the L-shaped clamping plate 86. The lower part of the movable frame 83 is connected to two front and rear support rods 88, and the two support rods 88 are respectively located in the slots 87 on the two L-shaped clamping plates 86 to support the L-shaped clamping plates 86. The two L-shaped clamping plates 86 connected to the same connecting block 85 can contact each other after swinging downward to a horizontal position to prevent the L-shaped clamping plates 86 from swinging downward excessively. The clamping part of the L-shaped clamping plate 86 is connected There is a rubber plate, through which the rubber disc on the ultrafiltration membrane assembly 1 can be buffered and protected to prevent the L-shaped clamping plate 86 from directly squeezing the rubber disc on the ultrafiltration membrane assembly 1 and causing damage to the rubber disc. The top of the support plate 7 is slidably connected to two front and rear clamping rods 810 that can approach each other through a slide groove. The support plate 7 is rotatably connected to a bidirectional screw rod 89, which is threadedly connected to the clamping rod 810. The height of the clamping rod 810 is lower than the diameter of the circular rubber disc on the cylindrical ultrafiltration membrane assembly 1 to avoid clamping. The rod 810 prevents the L-shaped clamping plate 86 from clamping the circular rubber disc on the cylindrical ultrafiltration membrane assembly 1, and the height of the clamping rod 810 is lower than the height of the square rubber disc on the curtain-type ultrafiltration membrane assembly 1, so as to avoid the clamping rod 810 preventing the L-shaped clamping plate 86 from clamping the square rubber disc on the curtain-type ultrafiltration membrane assembly 1. A rubber sleeve is connected to the clamping rod 810, and the rubber disc on the ultrafiltration membrane assembly 1 can be buffered and protected by the rubber sleeve, so as to avoid the clamping rod 810 directly and hard squeezing the rubber disc on the ultrafiltration membrane assembly 1 and causing damage to the rubber disc.

[0036] The ultrafiltration membrane assembly 1 to be cut is placed on the support plate 7, and the two rubber discs on the ultrafiltration membrane assembly 1 are respectively located on the two support plates 7. The right support plate 7 can be moved by rotating the screw 12 to adjust the spacing between the left and right support plates 7 to accommodate ultrafiltration membrane assemblies 1 of different lengths. The rubber disc on the ultrafiltration membrane assembly 1 can be clamped and limited by rotating the bidirectional screw 89 to make the front and rear clamping rods 810 close to each other, so as to avoid the displacement of the ultrafiltration membrane assembly 1 affecting the clamping effect when the subsequent L-shaped clamping plate 86 moves down to clamp the rubber disc on the ultrafiltration membrane assembly 1. Initially, the front and rear two L-shaped clamps 86 are in an eight-shaped shape. If the cylindrical ultrafiltration membrane assembly 1 needs to be cut, the electric push rod I 82 is directly controlled to drive the movable frame 83 to drive the electric push rod II 84 to move downward, thereby driving the front and rear two L-shaped clamps 86 in an eight-shaped shape to move downward, and the circular rubber disc on the cylindrical ultrafiltration membrane assembly 1 is clamped and fixed on the support plate 7. By making the front and rear two L-shaped clamps 86 in an eight-shaped shape, the contact area between the L-shaped clamps 86 and the circular rubber disc can be increased, so that the circular rubber disc on the cylindrical ultrafiltration membrane assembly 1 can be clamped more firmly. If it is the curtain ultrafiltration membrane assembly 1 that needs to be cut, the electric push rod II 84 is first controlled to drive the connecting block 85 to move downward. Since the L-shaped clamping plate 86 is supported by the support rod 88, the connecting block 85 moves downward and drives the L-shaped clamping plate 86 to swing downward to a horizontal state. Then the electric push rod I 82 is controlled to drive the movable frame 83 to drive the electric push rod II 84 to move downward, thereby driving the L-shaped clamping plate 86 in a horizontal state to move downward, and the square rubber disc on the curtain ultrafiltration membrane assembly 1 is clamped and fixed on the support plate 7. By making the L-shaped clamping plates 86 on the front and rear sides in a horizontal state, the contact area between the L-shaped clamping plate 86 and the square rubber disc can be increased, so that the square rubber disc on the curtain ultrafiltration membrane assembly 1 can be clamped more firmly. In this way, the clamp 8 of the present device can adapt to clamping the cylindrical ultrafiltration membrane assembly 1 and the curtain ultrafiltration membrane assembly 1, and realizes effective clamping and positioning of the two types of ultrafiltration membrane assemblies 1, which not only improves the practicability of the device, but also enhances its adaptability.

[0037] After the ultrafiltration membrane assembly 1 is clamped and fixed, the X-axis moving platform 6 is controlled to drive the support plate 7 to move to the left, thereby driving the ultrafiltration membrane assembly 1 to enter the dust collecting cover 3 to the left, and then the two rodless cylinders 91 are controlled to work to drive the two lifting plates 92 to approach each other, so that the upper and lower rubber strips 95 are pushed to approach each other and closely adhere to the left rubber disc on the ultrafiltration membrane assembly 1 through the lifting rods 93 on the upper and lower sides, and the elastic cloth cover 97 is stretched accordingly. When the lifting rods 93 located just above and just below the left rubber disc contact the left rubber disc, the lifting rods 93 in contact with the left rubber disc are resisted and cannot move further, so that the two lifting plates 92 continue to approach each other, compressing the spring I 94 on the lifting rod 93 in contact with the left rubber disc, and the lifting rod 93 located on the side of the left rubber disc continues to move, so that the front and rear sides of the rubber strip 95 are bent in the direction close to the left rubber disc. At the same time, the movable block 98 is pulled by the pull rope 99 to move in the direction close to the rubber strip 95, and the spring II 910 is compressed accordingly. The front and rear sides of the rubber strip 95 are bent toward the left rubber disc, which can ensure that the rubber strip 95 fits tightly with the left rubber disc. The rubber strip 95 and the elastic cloth cover 97 cooperate to seal the inlet and outlet 31 to effectively isolate the cutting space, thereby preventing debris and dust from flying during cutting, preventing the working environment from being polluted by debris and dust, and preventing workers from inhaling air contaminated by debris and dust for a long time, thereby protecting the workers' health.

[0038] Controlling the Y-axis moving platform 4 to work can drive the reciprocating saw 5 to move back and forth to cut the rubber disc entering the dust cover 3, so as to cut off part of the rubber disc and expose the end of the ultrafiltration membrane filament. When cutting, the vacuum cleaner 10 can be controlled to work, and the debris dust generated during cutting can be sucked into the vacuum cleaner 10 through the pipeline 11 for collection (the vacuum cleaner 10 is a prior art and will not be described here), so as to avoid the debris dust floating out from the inlet and outlet 31 after the subsequent two rubber strips 95 are separated from each other. After the cutting work is completed, the two rodless cylinders 91 are controlled to work to drive the two lifting plates 92 to move away from each other, so that the upper and lower rubber strips 95 are pulled away from each other and separated from the left rubber disc on the ultrafiltration membrane assembly 1 through the lifting rods 93 on the upper and lower sides. At the same time, under the reset action of the spring II 910, the movable block 98 can be pushed to move in the direction away from the rubber strip 95, so that the rubber strip 95 is pulled straight and restored to a horizontal state through the pull ropes 99 on the front and rear sides, so as to avoid affecting the subsequent ultrafiltration membrane assembly 1 entering and exiting the dust cover 3. After the rubber strip 95 is separated from the ultrafiltration membrane assembly 1, the X-axis moving platform 6 is controlled to drive the support plate 7 to move rightward, thereby driving the ultrafiltration membrane assembly 1 to move rightward out of the dust hood 3, and then the electric push rod Ⅰ82 is controlled to drive the movable frame 83 to drive the electric push rod Ⅱ84 to move upward, thereby driving the L-shaped clamping plate 86 to move upward to release the ultrafiltration membrane assembly 1. If the curtain ultrafiltration membrane assembly 1 needs to be cut, the curtain ultrafiltration membrane assembly 1 is manually rotated so that the uncut square rubber disc on the curtain ultrafiltration membrane assembly 1 faces left, and then the curtain ultrafiltration membrane assembly 1 is sent into the dust hood 3 again for secondary cutting, and the cutting work of the two square rubber discs on the curtain ultrafiltration membrane assembly 1 can be completed.

[0039] See also Figure 1 and Fig.10A positioning mechanism for positioning the ultrafiltration membrane assembly 1 is provided at the top of the base 2, and the positioning mechanism includes two front and rear guide rails 141 connected to the top of the base 2, the guide rail 141 is located on the right side of the dust collecting cover 3, and the guide rail 141 is installed in a tilted manner with the left lower and the right higher. A positioning rod frame 142 for positioning the ultrafiltration membrane assembly 1 is slidably connected in the guide rail 141, and the positioning rod frame 142 includes a cross bar and a vertical rod, and the cross bar is slidably connected in the two guide rails 141, and four vertical rods are connected to the top of the cross bar at even intervals along the axial direction, and the four vertical rods are located between the two guide rails 141. The top of the base 2 is slidably connected to a slotted slide 143 located on the right side of the dust collecting cover 3 through a slide groove, and the slotted slide 143 is located between the two guide rails 141, and the slotted slide 143 is U-shaped, and the cross bar on the positioning rod frame 142 is slidably connected to the open slide In the groove of the slotted skateboard 143, the vertical rod on the positioning rod frame 142 is located outside the groove of the slotted skateboard 143, and a guide column is connected to the groove of the slotted skateboard 143. The guide column passes through the cross bar on the positioning rod frame 142 to guide the positioning rod frame 142 to prevent the positioning rod frame 142 from rotating and deviating when moving. Two front and rear L-shaped pull rods 144 are connected to the right side surface of the slotted skateboard 143, and a receiving groove for accommodating the guide rail 141, the positioning rod frame 142, the slotted skateboard 143 and the L-shaped pull rod 144 is opened on the left side of the mobile platform of the X-axis mobile platform 6. Two front and rear push blocks 145 are connected to the receiving groove of the mobile platform on the X-axis mobile platform 6. The two push blocks 145 are respectively in contact with the two L-shaped pull rods 144, and two springs III 146 are symmetrically connected front and back between the slotted skateboard 143 and the base 2.

[0040] Initially, the L-shaped pull rod 144 is pulled by the push block 145, thereby pulling the slotted slide 143, the spring III 146 is stretched, and the positioning rod frame 142 is in a raised state. The ultrafiltration membrane assembly 1 can be positioned through the positioning rod frame 142 to ensure that each ultrafiltration membrane assembly 1 is placed in a consistent position, thereby ensuring that the length of each ultrafiltration membrane assembly 1 entering the cutting area is consistent, thereby achieving accurate and consistent cutting of the ultrafiltration membrane assembly 1. When the X-axis moving platform 6 drives the ultrafiltration membrane assembly 1 to the left and enters the dust collecting hood 3, it drives the push block 145 to move to the left and loosens the L-shaped pull rod 144. Under the resetting action of the spring III 146, the slotted slide 143 can be pulled to the left. The slotted slide 143 moves to the left and drives the positioning rod frame 142 to move to the left. Under the guidance of the guide rail 141 installed in an inclined manner with the left low and the right high, the positioning rod frame 142 moves to the left and descends at the same time to avoid the ultrafiltration membrane assembly 1 and avoid hindering the ultrafiltration membrane assembly 1 from entering the dust collecting hood 3 for cutting. When the X-axis moving platform 6 drives the ultrafiltration membrane assembly 1 to move to the right out of the dust collecting cover 3, it drives the push block 145 to move to the right and reset. When the push block 145 moves to the right and contacts with the L-shaped pull rod 144, the push block 145 continues to move to the right and pulls the L-shaped pull rod 144 to move the slotted slide 143 to the right and reset. The spring III 146 is stretched accordingly, and the slotted slide 143 moves to the right and drives the positioning rod frame 142 to move to the left. The positioning rod frame 142 is guided by the guide rail 141 so that the positioning rod frame 142 moves to the right and rises at the same time to position the next ultrafiltration membrane assembly 1 that needs to be cut.

The blocking net 15 can block large waste chips to prevent large waste chips from entering the pipe 11 and clogging the pipe 11. The vibration motor 16 can make the blocking net 15 vibrate to shake off the waste chips remaining thereon to prevent the blocking net 15 from being blocked.

[0042] See also Figure 2-Figure 3 A collecting frame 17 with an open top and bottom is embedded at the bottom of the dust collecting hood 3. The bottom of the collecting frame 17 passes through the base 2. An electric rotating baffle 18 for blocking waste chips is provided in the collecting frame 17. The electric rotating baffle 18 includes a baffle and a stepper motor. The baffle is rotatably connected in the collecting frame 17. The stepper motor is installed on the front outer wall of the collecting frame 17. The output shaft of the stepper motor is connected to the front side of the baffle. The waste chips in the collecting frame 17 can be discharged downward by controlling the stepper motor to drive the baffle to rotate to a vertical state. The waste chips can be blocked in the collecting frame 17 by controlling the stepper motor to drive the baffle to rotate back to a horizontal state.

[0043] The part of the rubber disc cut off from the ultrafiltration membrane assembly 1 will fall onto the electric rotating baffle 18 in the collection frame 17 to collect the waste chips. The electric rotating baffle 18 can be controlled to rotate to a vertical state to discharge the waste chips in the collection frame 17 downward, without the need for manual cleaning of the waste chips, which can save time and effort. The electric rotating baffle 18 can be controlled to rotate back to a horizontal state to block the waste chips in the collection frame 17 to prevent the debris from floating downward through the collection frame 17 during cutting.
