Description

Technical Field

[0001] This utility model relates to a central tube feeding and RO membrane roll unloading device. Background Technology

[0002] Currently, film winding machines are an indispensable piece of equipment in the RO membrane production process. They can roll components such as membrane sheets, separators, and central tubes into RO membranes. For example, Chinese patent CN219636471U discloses a manual household film winding machine. Film winding machines typically have a winding mechanism and a tape wrapping mechanism. During the winding process, the central tube is first loaded and installed in the winding mechanism. Then, the membrane sheet and separator are connected to the central tube, and the winding mechanism drives the central tube to rotate, thus winding the membrane sheet and separator into an RO membrane roll. The tape wrapping mechanism then uses tape to wrap the wound RO membrane roll, and finally, the wrapped RO membrane roll is removed from the winding mechanism. However, in existing film winding machines, the loading of the central tube into the winding mechanism and the removal of the RO membrane roll are usually done manually. This not only increases labor costs and the labor intensity of workers but also affects the efficiency of loading the central tube and unloading the RO membrane roll. Utility Model Content

[0026] The rotating shaft is rotatably connected to the frame, and the material support claw is connected to the rotating shaft and is used to rotate with the rotating shaft. During the rotation, the material support claw has an initial tilted position and is used to rotate upward from the initial position.

[0046] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0047] like Figures 1-5 As shown, a central tube feeding and RO membrane roll unloading device includes a frame, a hopper 1, a material support component 2, a feeding mechanism 3, a pushing mechanism 4, and a conveying mechanism 5;

[0048] Both the hopper 1 and the material support component 2 are connected to the frame. The hopper 1 is used to store the central tube 6. The material support component 2 is provided with a material support trough 7, which has a material receiving station and a material receiving station.

[0049] The feeding mechanism 3 is used to lift the central tube 6 in the hopper 1 and transport it to the material receiving station in the material receiving trough 7;

[0050] The pushing mechanism 4 is used to push and move the central tube 6 in the receiving station to the unloading station;

[0051] The conveying mechanism 5 is used to pick up the central tube 6 in the material unloading station of the material tray 7 and transport the picked-up central tube 6 to the winding mechanism 8. The conveying mechanism 5 is also used to pick up the RO membrane rolls wound up in the winding mechanism 8 and transport the picked-up RO membrane rolls for unloading.

[0052] Specifically, the frame is also connected to a winding mechanism 8 and a tape wrapping mechanism 9. The specific structures of the winding mechanism 8 and the tape wrapping mechanism 9 are existing technologies well known to those skilled in the art, and will not be described in detail in this embodiment. In this embodiment, the feeding mechanism 3 first lifts the central tube 6 in the hopper 1 and transports it to the receiving station in the material receiving trough 7. Then, the pushing mechanism 4 pushes the central tube 6 in the receiving station to the unloading station. Then, the handling mechanism 5 picks up the central tube 6 in the unloading station in the material receiving trough 7 and transports the picked-up central tube 6 to the winding mechanism 8. Then, the membrane and the spacer are connected to the central tube 6, and the winding mechanism 8 drives the central tube 6 to rotate, thereby winding the membrane and the spacer to obtain an RO membrane roll. Then, the tape wrapping mechanism 9 uses tape to wrap the RO membrane roll. Then, the handling mechanism 5 picks up the RO membrane roll and unloads it. This realizes the automatic feeding of the central tube 6 to the winding mechanism 8 and the removal of the RO membrane roll from the winding mechanism 8 without manual operation, reducing labor costs and the labor intensity of workers, and improving the efficiency of feeding the central tube 6 and unloading the RO membrane roll. The material support groove 7 is located on the top of the material support component 2, and the material support groove 7 can be a V-shaped groove.

[0053] like Figure 1 , 2 As shown, the central tube feeding and RO membrane roll unloading device may further include a conveying mechanism 10, on which a material box 11 is placed. The conveying mechanism 5 is used to pick up the RO membrane rolls wound up in the winding mechanism 8 and transport the picked-up RO membrane rolls to the material box 11 on the conveying mechanism 10. Then, when the material box 11 is full, the conveying mechanism 10 can transport the material box 11 away. The conveying mechanism 10 may be a roller conveyor.

[0054] like Figure 1 , 3 As shown in Figures 1 and 4, the conveying mechanism 5 may include a moving mechanism, a first lifting mechanism 12, a second lifting mechanism 13, a gripping mechanism 14, and a suction mechanism 15;

[0055] The gripping mechanism 14 is connected to the first lifting mechanism 12 and is used to grip the central tube 6;

[0056] The first lifting mechanism 12 is connected to the moving mechanism and is used to drive the gripping mechanism 14 to move up and down;

[0057] The suction mechanism 15 is connected to the second lifting mechanism 13 and is used to suction the RO membrane roll;

[0058] The second lifting mechanism 13 is connected to the moving mechanism and is used to drive the suction mechanism 15 to move up and down;

[0059] The moving mechanism is connected to the frame and is used to drive the first lifting mechanism 12 and the second lifting mechanism 13 to move back and forth, thereby driving the gripping mechanism 14 and the suction mechanism 15 to move back and forth.

[0060] Specifically, the process of the conveying mechanism 5 conveying the center tube 6 is as follows: First, the moving mechanism drives the gripping mechanism 14 to move back and forth above the unloading station. Then, the first lifting mechanism 12 drives the gripping mechanism 14 to move down into place. Then, the gripping mechanism 14 grabs the center tube 6 in the unloading station. Then, the first lifting mechanism 12 drives the gripping mechanism 14 to rise. Then, the moving mechanism drives the gripping mechanism 14 to move back and forth above the winding mechanism 8. Then, the first lifting mechanism 12 drives the gripping mechanism 14 to move down into place. Then, when the winding mechanism 8 clamps the center tube 6, the gripping mechanism 14 releases the center tube 6. Then, the first lifting mechanism 12 drives the gripping mechanism 14 to rise again, thereby completing the feeding of the center tube 6. More specifically, the process of the conveying mechanism 5 conveying the RO membrane roll for unloading is as follows: After the winding mechanism 8 winds up the RO membrane roll, the moving mechanism first drives the suction mechanism 15 to move back and forth above the winding mechanism 8. Then, the second lifting mechanism 13 drives the suction mechanism 15 to move down to its position. Then, the suction mechanism 15 sucks up the RO membrane roll wound up in the winding mechanism 8. Then, when the winding mechanism 8 releases the RO membrane roll, the second lifting mechanism 13 drives the suction mechanism 15 to rise. Then, the moving mechanism drives the suction mechanism 15 to move back and forth above the material box 11 on the conveying mechanism 10. Then, the second lifting mechanism 13 drives the suction mechanism 15 to move down to its position again. Then, the suction mechanism 15 releases the RO membrane roll into the material box 11. Then, the second lifting mechanism 13 drives the suction mechanism 15 to rise again, thus completing the unloading of the RO membrane roll.

[0061] like Figure 1 , 3 As shown in Figures 1 and 4, the moving mechanism may include a first linear module 16, a second linear module 17, and a moving base 18.

[0062] One end of the movable seat 18 is connected to the first linear module 16, and the other end of the movable seat 18 is connected to the second linear module 17. The first lifting mechanism 12 and the second lifting mechanism 13 are both connected to the movable seat 18.

[0063] The first linear module 16 and the second linear module 17 are respectively connected to the frame and are used to drive the moving seat 18 to move back and forth, thereby driving the first lifting mechanism 12 and the second lifting mechanism 13 to move back and forth, thereby driving the gripping mechanism 14 and the suction mechanism 15 to move back and forth; specifically, the first linear module 16 and the second linear module 17 are synchronously connected through a transmission shaft.

[0064] like Figure 1 , 3 As shown in Figures 1 and 4, the first lifting mechanism 12 may include a lifting cylinder, and the gripping mechanism 14 may include a pneumatic gripper 19, a first gripping block 20, and a second gripping block 21.

[0065] The first clamping block 20 and the second clamping block 21 are respectively connected to the pneumatic gripper 19. The pneumatic gripper 19 is used to drive the first clamping block 20 and the second clamping block 21 to close together to clamp the central tube 6. The pneumatic gripper 19 is also used to drive the first clamping block 20 and the second clamping block 21 to separate to release the central tube 6.

[0066] The pneumatic gripper 19 is connected to the lifting cylinder, and the lifting cylinder is connected to the movable base 18 and is used to drive the pneumatic gripper 19 to move up and down.

[0067] The material support component 2 is provided with a clamping groove 22 for the first clamping block 20 and the second clamping block 21 to clamp the central tube 6 in the material removal station.

[0068] like Figure 1 , 3 As shown in Figures 1 and 4, the second lifting mechanism 13 may include a lifting linear module, and the suction mechanism 15 may include a mounting base 23 and a suction cup component 24.

[0069] The suction cup component 24 is connected to the mounting base 23 and a negative pressure source to hold the RO membrane roll. The mounting base 23 is connected to the lifting linear module, which is connected to the movable base 18 and drives the mounting base 23 and the suction cup component 24 to move up and down. Specifically, the suction cup component 24 is connected to the negative pressure source through a pipeline, and a solenoid valve is connected in the pipeline. When the solenoid valve is open, the suction cup component 24 can hold the RO membrane roll, and when the solenoid valve is closed, the suction cup component 24 can release the RO membrane roll. The specific structure of the suction cup component 24 is prior art well known to those skilled in the art, and will not be described in detail in this embodiment.

[0070] like Figures 5-8 As shown, the feeding mechanism 3 may include a rotating shaft 25, a limiting component, a guide plate 26, a material supporting component 27, and at least two material supporting claws 28;

[0071] The rotating shaft 25 is rotatably connected to the frame, and the material support claw 28 is connected to the rotating shaft 25 and is used to rotate with the rotating shaft 25. The material support claw 28 has an inclined initial position during rotation and is used to rotate upward from the initial position.

[0072] The limiting component is connected to the frame and the rotating shaft 25 respectively, and is used to limit the downward rotation of the material support claw 28 from the initial position by limiting the rotation of the rotating shaft 25 when the material support claw 28 rotates to the initial position;

[0073] The guide plate 26 is inclinedly connected to the frame. The higher end of the guide plate 26 is connected to the lower end of the material support claw 28 that has been rotated to the initial position. The lower end of the guide plate 26 is connected to the material receiving station in the material support trough 7.

[0074] The material support assembly 27 is used to support the central tube 6 in the hopper 1. When the material support assembly 27 lifts the central tube 6 upward, the central tube 6 is used to abut against the material support claw 28 in the initial position and push the material support claw 28 to rotate upward. When the central tube 6 lifted by the material support assembly 27 rises above the material support claw 28, the material support claw 28 is used to rotate back to the initial position. When the material support assembly 27 drives the central tube 6 downward, the material support claw 28 is used to support the central tube 6 on the material support assembly 27 and guide the central tube 6 to roll onto the guide plate 26, thereby causing the central tube 6 to roll down into the material receiving station in the material support trough 7.

[0075] Specifically, the material support claw 28 can rotate upward from the initial position following the rotation axis 25. When the material support claw 28 rotates downward to the initial position, the limiting component will restrict the rotation axis 25 from rotating, thereby restricting the material support claw 28 from continuing to rotate downward, thus keeping the material support claw 28 in the initial position. The feeding mechanism 3 operates as follows: First, the material support assembly 27 lifts a central tube 6 from the hopper 1. As the material support assembly 27 lifts the central tube 6 upwards, the central tube 6 abuts against the material support claw 28 in its initial position, causing the claw 28 to rotate upwards. Then, the central tube 6 rises above the material support claw 28. At this point, the material support claw 28 rotates back to its initial position under its own gravity. Then, the material support assembly 27 lowers the central tube 6. During the descent, the central tube 6 is supported by the material support claw 28, and then rolls along the inclined material support claw 28 onto the guide plate 26 and then rolls down from the guide plate 26 into the material receiving station in the material receiving trough 7. In this embodiment, multiple material support claws 28 are arranged side by side.

[0076] Specifically, the limiting component includes a limiting block 29 and a limiting bolt 30. The limiting block 29 is connected to the frame, and the limiting bolt 30 is connected to the rotating shaft 25. When the material support claw 28 rotates to the initial position with the rotating shaft 25, the limiting bolt 30 abuts against the limiting block 29, thereby restricting the rotation of the rotating shaft 25 and thus restricting the material support claw 28 from rotating downward from the initial position.

[0077] More specifically, the material support component 2 is connected to a baffle 31, the guide plate 26 is located on one side of the material receiving station in the material support trough 7, and the baffle 31 is located on the other side of the material receiving station in the material support trough 7. The baffle 31 is used to prevent the central tube 6 from rolling down from the guide plate 26 into the material receiving station.

[0078] like Figures 5-8 As shown, the material support assembly 27 may include a material support cylinder 32 and a material support base 33;

[0079] The material support 33 is connected to the material support cylinder 32, and the material support cylinder 32 is connected to the frame and is used to drive the material support 33 to move up and down.

[0080] The material support base 33 has at least two columns 34. The bottom of the hopper 1 is provided with a through hole corresponding to the column 34. The top of the column 34 is provided with a top groove 35 for supporting the central tube 6. The column 34 is used to extend into the corresponding through hole and lift the central tube 6 in the hopper 1 through the top groove 35 when the material support cylinder 32 drives the material support base 33 to rise.

[0081] like Figure 6 As shown, the pushing mechanism 4 includes a pushing drive component 36 and a pushing plate 37;

[0082] The pusher plate 37 is connected to the pusher drive component 36 and is used to abut against the central tube 6 in the material support groove 7;

[0083] The pushing drive component 36 is connected to the frame and is used to drive the pushing plate 37 to move so that the pushing plate 37 pushes the central tube 6 in the incoming station to the outgoing station; in this embodiment, the pushing drive component 36 can be a rodless cylinder, and the material support component 2 is connected to a first sensor for detecting the central tube 6 in the incoming station and a second sensor for detecting the central tube 6 in the outgoing station.

[0084] In summary, the frame is also connected to a winding mechanism 8 and a tape wrapping mechanism 9. The specific structures of the winding mechanism 8 and the tape wrapping mechanism 9 are existing technologies well known to those skilled in the art, and will not be described in detail in this embodiment. In this embodiment, the feeding mechanism 3 first lifts the central tube 6 in the hopper 1 and transports it to the receiving station in the material receiving trough 7. Then, the pushing mechanism 4 pushes the central tube 6 in the receiving station to the unloading station. Then, the handling mechanism 5 picks up the central tube 6 in the unloading station in the material receiving trough 7 and transports the picked-up central tube 6 to the winding mechanism 8. Then, the membrane and the spacer are connected to the central tube 6, and the winding mechanism 8 drives the central tube 6 to rotate, thereby winding the membrane and the spacer to obtain an RO membrane roll. Then, the tape wrapping mechanism 9 uses tape to wrap the RO membrane roll. Then, the handling mechanism 5 picks up the RO membrane roll and unloads it. This realizes the automatic feeding of the central tube 6 to the winding mechanism 8 and the removal of the RO membrane roll from the winding mechanism 8 without manual operation, reducing labor costs and the labor intensity of workers, and improving the efficiency of feeding the central tube 6 and unloading the RO membrane roll.

[0085] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
