Description

Technical Field

[0001] This utility model relates to the field of filter screen production technology, and in particular to a filter screen folding device. Background Technology

[0002] In the production of filter screens, filter screen folding machines are needed to fold the filter paper, thereby improving production efficiency.

[0003] In the prior art, Chinese Patent Publication No. CN219469237U discloses a folding device for an automatic filter screen processing equipment. Its advantage is that by adjusting the position of the second folding roller, it can always fit closely to the filter screen cloth according to the thickness of different filter screen cloths, ensuring the pressure applied to the filter screen cloth, preventing the filter screen cloth from being folded too large and not compact, and ensuring the folding effect.

[0004] Although the aforementioned patent allows for adjustments based on different filter cloth thicknesses, the raw materials, i.e., the filter cloth rolls, need to be manually changed repeatedly during feeding, which is time-consuming and labor-intensive, affecting production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a filter screen folding device that can improve the speed of changing filter screen cloth rolls and thus improve the filter screen folding efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a filter screen folding device, including a folding machine, a base plate fixedly installed on the front of the folding machine, an mounting plate fixedly installed on one side of the upper surface of the base plate, a first support frame fixedly installed on one side of the upper surface of the mounting plate, an adjusting plate hinged to the top of the first support frame, a slide rail fixedly installed on the lower surface of the adjusting plate, a round rod slidably connected inside the slide rail, a first electric push rod fixedly connected to one end of the round rod, a second support frame hinged to the bottom of the first electric push rod, the bottom of the second support frame fixedly connected to the mounting plate, a first motor fixedly installed on the top of the adjusting plate, a rotating shaft fixedly connected to the output end of the first motor, a placement frame fixedly installed on the other side of the upper surface of the base plate, a U-shaped placement plate fixedly installed on the top of the placement frame, a roll of material placed inside the U-shaped placement plate, a lead screw slide fixedly installed on the back of the placement frame, a slider slidably connected inside the lead screw slide, and a push rod fixedly connected to the top of the slider.

[0007] By adopting the above technical solution, the folding machine is used to fold the raw material filter paper of the filter screen for easy subsequent assembly. The base plate is used to install components that increase the material changing speed, and the mounting plate is used to install components that discharge material. The top of the first support frame is hinged to the adjusting plate, which can adjust its angle. A sliding rod slides inside the slide rail. When the first electric push rod extends, it can push the rod to move within the slide rail, raising the angle of the side of the adjusting plate away from the first support frame. When the first electric push rod retracts, it drives the rod to move within the slide rail, lowering the angle of the side of the adjusting plate away from the first support frame. The first motor and the rotating shaft can follow the adjustment plate to adjust their angle. The motor drives the rotating shaft to rotate, which releases the filter paper from the roll for feeding. When additional material is needed, the angle of the adjusting plate is leveled. A U-shaped placing plate is installed on the top of the placing frame to hold multiple rolls at once. When the adjusting plate is leveled, the end of the rotating shaft aligns with the hole inside the roll. The starter screw slide can drive the slider to move via the internal screw. When the slider moves, it drives the push rod to move, which can push the roll placed in the U-shaped placing plate onto the rotating shaft. The rotating shaft releases material as it rotates. After the filter paper on the roll has been released, the first electric push rod can be retracted to tilt the adjusting plate, making it easier to remove the empty roll.

[0008] A further feature of this invention is that a mounting rod is fixedly installed on one side of the outer surface of the rotating shaft, and a second electric push rod is fixedly installed on the top of the mounting rod.

[0009] By adopting the above technical solution, the mounting rod is used to install the second electric push rod.

[0010] A further feature of this invention is that a limiting plate is fixedly connected to one end of the second electric push rod, and a rubber pad is fixedly connected to the side of the limiting plate away from the second electric push rod.

[0011] By adopting the above technical solution, the second electric push rod is used to push the limit plate to move and remove the empty roll material. The rubber pad is used for anti-slip on one side, and the limit plate is also used to limit the roll material during feeding.

[0012] A further feature of this invention is that both the limiting plate and the rubber pad have a circular hole in the middle.

[0013] By adopting the above technical solution, the circular hole prevents the limiting plate and rubber pad from interfering with the rotating shaft when they move. The diameter of the circular hole is slightly larger than the outer diameter of the rubber sleeve to prevent interference.

[0014] A further feature of this invention is that a rubber sleeve is fixedly connected to the other side of the outer surface of the rotating shaft, and a guide cone is fixedly connected to one end of the rotating shaft.

[0015] By adopting the above technical solution, the outer diameter of the rubber sleeve is slightly larger than the diameter of the internal holes of the roll. When the roll is pushed onto the rubber sleeve on the outer surface of the shaft, the rubber sleeve is elastic and can clamp the roll to prevent it from loosening when it is unloaded. The guide cone makes the roll fit onto the rubber sleeve more smoothly.

[0016] A further feature of this invention is that a conveyor belt is fixedly installed in the middle of the upper surface of the base plate, and a baffle is fixedly installed on the side of the placement frame near the conveyor belt.

[0017] By adopting the above technical solution, the conveyor belt is used to transport the falling empty rolls of material, and the baffle prevents the falling rolls of material from falling out.

[0018] A further feature of this invention is that a third electric push rod is fixedly installed on the front side of the base plate, and a movable plate is fixedly connected to one end of the third electric push rod.

[0019] By adopting the above technical solution, the third electric push rod is used to push the moving plate to move.

[0020] A further feature of this invention is that a first locking block is fixedly connected to the front of the movable plate, and a second locking block is fixedly installed on both sides of the movable plate.

[0021] By adopting the above technical solution, the first and second locking blocks are used to lock the placement box and prevent it from shaking.

[0022] A further feature of this invention is that a wheel frame is rotatably connected to the bottom of the movable plate, and a rotating wheel is rotatably connected inside the wheel frame.

[0023] By adopting the above technical solution, a rotating wheel is installed inside the wheel frame to support the movement of the moving plate.

[0024] A further feature of this invention is that a placement box is movably connected to the top of the movable plate, and a placement groove is provided in the middle of the placement box.

[0025] By adopting the above technical solution, when the replaced roll material is conveyed by the conveyor belt, the placement slot in the middle of the placement box catches the empty roll material shell, and at the same time the moving plate can move and can be stacked horizontally, reducing the labor intensity of employees.

[0026] The beneficial effects of this utility model are: it can improve the speed of replacing filter cloth rolls and thus improve the filter folding efficiency. In use, multiple rolls of filter material are placed on a U-shaped placement plate. The first electric push rod is activated to extend, raising the angle of the adjustment plate away from the first support frame and leveling it. Then, the screw slide is activated to drive the slider through the internal screw, and the push rod is used to push the rolls placed in the U-shaped placement plate onto the rotating shaft. One end of the roll abuts against the rubber pad connected to the limiting plate for positioning. The rubber pad is elastic and can prevent the roll from loosening when rotating and releasing material. Then, the first motor is activated to drive the rotating shaft to rotate. When the rotating shaft rotates, the filter paper on the roll is released for feeding. After the filter paper on the roll is folded, the first electric push rod retracts, lowering the angle of the adjustment plate away from the first support frame. At this time, the rotating shaft tilts, and the second electric push rod is activated to push the limiting plate to move, removing the empty roll, which facilitates the replacement of the roll, reduces the labor intensity of employees, and improves the folding efficiency.

A round hole 22 is opened in the middle of both the limit plate 20 and the rubber pad 21. A rubber sleeve 23 is fixedly connected to the other side of the outer surface of the rotating shaft 11. A guide cone 24 is fixedly connected to one end of the rotating shaft 11. A conveyor belt 25 is fixedly installed in the middle of the upper surface of the base plate 2. The placement rack 1 A baffle 26 is fixedly installed on one side near the conveyor belt 25. A third electric push rod 27 is fixedly installed on the front of the base plate 2. A movable plate 28 is fixedly connected to one end of the third electric push rod 27. A first locking block 29 is fixedly connected to the front of the movable plate 28. A second locking block 30 is fixedly installed on both sides of the movable plate 28. A wheel frame 31 is rotatably connected to the bottom of the movable plate 28. A rotating wheel 32 is rotatably connected inside the wheel frame 31. A placement box 33 is movably connected to the top of the movable plate 28. A placement groove 34 is opened in the middle of the placement box 33. Specifically, the folding machine 1 is used to fold the raw filter paper of the filter screen for easy subsequent assembly. The base plate 2 is used to install components that increase the material changing speed. The mounting plate 3 is used to install components that discharge material. The top of the first support frame 4 is hinged to the adjusting plate 5, which can be adjusted in angle. A circular rod 7 slides inside the slide rail 6. When the first electric push rod 8 extends, it can push the circular rod 7 to move within the slide rail 6, raising the angle of the side of the adjusting plate 5 away from the first support frame 4. When the first electric push rod 8 retracts, it drives the circular rod 7 to move within the slide rail 6, lowering the angle of the side of the adjusting plate 5 away from the first support frame 4. The first motor 10 and the rotating shaft 11 can follow the adjustment plate 5 to adjust their angle. Machine 10 drives the rotating shaft 11 to rotate. When the rotating shaft 11 rotates, it releases the filter paper on the roll 14 for feeding. When additional material is needed, the angle of the adjusting plate 5 is leveled. A U-shaped placing plate 13 is installed on the top of the placing frame 12 to hold multiple rolls at once. When the adjusting plate 5 is leveled, the end of the rotating shaft 11 aligns with the holes inside the roll. The starting screw slide 15 drives the slider 16 to move via the internal screw. When the slider 16 moves, it drives the push rod 17 to move, which pushes the roll 14 placed in the U-shaped placing plate 13 onto the rotating shaft 11. The rotating shaft 11 releases material when it rotates. After the filter paper on the roll 14 has been released, the first electric push rod 8 can be retracted. The adjusting plate 5 is tilted to facilitate the removal of empty coil material. The mounting rod 18 is used to install the second electric push rod 19, which is used to push the limiting plate 20 to move and remove the empty coil material 14. The rubber pad 21 is used for anti-slip on one side. The limiting plate 20 is also used to limit the coil material 14 during loading. The round hole 22 prevents the limiting plate 20 and the rubber pad 21 from interfering with the rotating shaft 11 when they move. The diameter of the round hole 22 is slightly larger than the outer diameter of the rubber sleeve 23 to prevent interference. The outer diameter of the rubber sleeve 23 is slightly larger than the diameter of the internal hole of the coil material 14. When the coil material 14 is pushed onto the rubber sleeve 23 on the outer surface of the rotating shaft 11, the rubber sleeve 23 is elastic and can clamp the coil material 14 to prevent coiling. When the material is unloaded, the guide cone 24 makes it easier for the roll material 14 to be fitted onto the rubber sleeve 23. The conveyor belt 25 is used to transport the empty roll material 14 that has fallen. The baffle 26 prevents the roll material 14 from falling out. The third electric push rod 27 is used to push the moving plate 28 to move. The first locking block 29 and the second locking block 30 are used to lock the placement box 33 to prevent the placement box 33 from shaking. The wheel frame 31 has a rotating wheel 32 installed inside to support the movement of the moving plate 28. When the replaced roll material 14 is transported by the conveyor belt 25, the placement slot 34 opened in the middle of the placement box 33 catches the empty roll material 14 shell and notifies the moving plate 28 that it can move and can be stacked horizontally, reducing the labor intensity of employees. This invention improves the speed of replacing filter cloth rolls, thereby increasing filter folding efficiency. In use, multiple filter cloth rolls 14 are placed on a U-shaped placement plate 13. The first electric push rod 8 is extended. The top of the first support frame 4 is hinged to the adjusting plate 5, allowing the adjusting plate 5 to adjust its angle. When the first electric push rod 8 extends, it pushes the round rod 7 to move within the slide rail 6, raising and leveling the side of the adjusting plate 5 away from the first support frame 4. The end of the rotating shaft 11 aligns with the holes inside the roll. Then, the lead screw slide 15 is activated, driving the slider 16 via the internal lead screw. The push rod 17 pushes the roll 14 placed in the U-shaped placement plate 13 onto the rotating shaft 11. One end of the roll 14 presses against the rubber pad 21 connected to the limiting plate 20 for positioning. The outer diameter of the rubber sleeve 23 is slightly larger than the diameter of the holes inside the roll 14, and the rubber sleeve 23 is elastic. The mechanism ensures that the roll 14 remains secure during rotation and unloading. Then, the first motor 10 is activated to drive the rotating shaft 11 to rotate. As the shaft 11 rotates, the filter paper on the roll 14 is released for feeding. After the filter paper on the roll 14 is folded, the first electric push rod 8 retracts, causing the adjusting plate 5 to decrease in angle on the side away from the first support frame 4. At this time, the rotating shaft 11 tilts. The round hole 22 prevents interference between the limiting plate 20 and the rubber pad 21 and the rotating shaft 11 during movement. The diameter of the round hole 22 is slightly larger than the outer diameter of the rubber sleeve 23. The second electric push rod 19 is activated to push the limiting plate 20 to move, removing the empty roll 14. The empty roll 14 falls onto the conveyor belt 25, which transports the roll 14 to the placement slot 34 in the middle of the placement box 33. Simultaneously, the third electric push rod 27 is activated to push the moving plate 28 to move, allowing for horizontal stacking, facilitating the replacement of the roll 14, reducing employee workload, and improving folding efficiency.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
