Description

Technical Field

[0001] This utility model relates to a welding device for a central tube and a flow guide cloth. Background Technology

[0002] Currently, in the production process of RO membranes, it is necessary to weld the flow guide fabric to the central tube. However, most existing production equipment can only weld the central tube and the flow guide fabric at a single angle, and cannot weld at multiple angles. This leads to weak welds between the central tube and the flow guide fabric, posing a risk of detachment. For example, Chinese patent CN219214142U discloses a flow guide fabric cutting and welding machine. In this machine, a welding device is used to weld the last piece of flow guide fabric to the central tube supported by a support device. However, since the support device cannot rotate the central tube, the welding device can only weld the flow guide fabric to the central tube at a single angle, and cannot weld the central tube and the flow guide fabric at multiple angles. This results in weak welds between the central tube and the flow guide fabric, posing a risk of detachment. Utility Model Content

Then, a flow guide cloth is pulled over the central tube by manual traction or by a traction mechanism. Then, the welding mechanism operates to press the flow guide cloth over the central tube onto the central tube and perform ultrasonic welding on the flow guide cloth and the central tube, thus welding the central tube and the flow guide cloth at the first angle position.

[0057] 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.

[0058] like Figures 1-6 As shown, a welding device for a central tube and a guide cloth includes a frame 1, a support component 2, a tube clamping and rotating mechanism 3, and a welding mechanism 4.

[0059] The hosting component 2 is connected to the frame 1, and the central tube 5 is placed on the hosting component 2;

[0060] The clamping and rotating mechanism 3 is used to clamp the central tube 5 on the hosting component 2 and drive the clamped central tube 5 to rotate by an angle.

[0061] The welding mechanism 4 is connected to the frame 1 and is used to press the guide cloth 6 overlapping the central tube 5 onto the central tube 5 and to perform ultrasonic welding on the guide cloth 6 and the central tube 5. The welding mechanism 4 is also used to release the pressure of the guide cloth 6 on the central tube 5.

[0062] Specifically, firstly, a central tube 5 is transported and placed on the support component 2. Then, the tube clamping and rotating mechanism 3 clamps the central tube 5 on the support component 2 and rotates the clamped central tube 5 at a certain angle. Then, a guide cloth 6 is pulled manually or by the traction mechanism 100 and overlapped on the central tube 5. Then, the welding mechanism 4 operates to press the guide cloth 6 overlapped on the central tube 5 onto the central tube 5 and performs ultrasonic welding on the guide cloth 6 and the central tube 5, thus welding the central tube 5 and the guide cloth 6 at the first angle position. Then, the welding mechanism 4 operates to release the pressure on the guide cloth 6 on the central tube 5. Then, the tube clamping and rotating mechanism 3 rotates the central tube 5 at a certain angle. Then, the welding mechanism 4 operates again to press the guide cloth 6 onto the central tube 5 and perform ultrasonic welding on the guide cloth 6 and the central tube 5, thus welding the central tube 5 and the guide cloth 6 at the second angle position. The above operation is then repeated to weld the central tube 5 and the guide cloth 6 at a third or even more angular positions. This allows for welding of the central tube 5 and the guide cloth 6 at multiple angular positions, greatly improving the strength of the weld between the central tube 5 and the guide cloth 6, and thus preventing the guide cloth 6 from detaching from the central tube 5. After welding is completed, the clamping and rotating mechanism 3 releases the central tube 5 so that it is re-supported on the support member 2. In this embodiment, the central tube 5 and the guide cloth 6 are welded at three angular positions, with five weld points at each angular position, for a total of 15 weld points, greatly improving the strength of the connection between the central tube 5 and the guide cloth 6. Specifically, in this embodiment, the traction mechanism 100 is preferentially used to pull the guide cloth 6 to overlap the central tube 5. The specific mechanism of the traction mechanism 100 can adopt the traction device in Chinese Patent No. CN219214142U.

[0063] like Figures 1-3 As shown, the welding mechanism 4 includes, for example but not limited to, the following structure: a front-to-back moving assembly, a mounting frame 7, at least one ultrasonic welder 8, a lifting seat 9 corresponding to the ultrasonic welder 8, and a lifting drive component 10 corresponding to the lifting seat 9.

[0064] The ultrasonic welder 8 is connected to the corresponding lifting seat 9;

[0065] The lifting seat 9 is slidably connected to the mounting frame 7 in the vertical direction;

[0066] The mounting bracket 7 is connected to the front and rear moving assembly;

[0067] The forward and backward moving assembly is connected to the frame 1 and is used to drive the mounting frame 7 to move forward and backward relative to the frame 1, thereby driving the ultrasonic welder 8 to move forward and backward above the central tube 5.

[0068] The lifting drive component 10 is connected to the mounting frame 7 and the corresponding lifting seat 9. The lifting drive component 10 is used to drive the lifting seat 9 to move downward, thereby driving the corresponding ultrasonic welder 8 to move downward to press the guide cloth 6 overlapping the central tube 5 onto the central tube 5, and then perform ultrasonic welding on the guide cloth 6 and the central tube 5 by the ultrasonic welder 8. The lifting drive component 10 is also used to drive the lifting seat 9 to rise upward, thereby driving the ultrasonic welder 8 to rise upward to release the pressure on the guide cloth 6 on the central tube 5. Specifically, after the guide cloth 6 is pulled to overlap the central tube 5, the forward and backward moving component first drives the mounting frame 7 to move back and forth so that the ultrasonic welder 8 moves back and forth to directly above the central tube 5. Then, the lifting drive component 10 drives the lifting seat 9 to move downward, thereby driving the ultrasonic welder 8 to move downward to press the guide cloth 6 overlapping the central tube 5 onto the central tube 5. Then, the ultrasonic welder 8 performs ultrasonic welding on the guide cloth 6 and the central tube 5, and thus welds the central tube 5 and the guide cloth 6 at the first angle position. Then, the lifting drive 10 drives the lifting seat 9 to rise, thereby lifting the ultrasonic welder 8 to release the guide cloth 6 pressing on the central tube 5. Then, the clamping and rotating mechanism 3 drives the central tube 5 to rotate a certain angle. Then, the lifting drive 10 again drives the lifting seat 9 to move downwards, thereby moving the ultrasonic welder 8 downwards until the guide cloth 6 is pressed onto the central tube 5. The ultrasonic welder 8 then performs ultrasonic welding on the guide cloth 6 and the central tube 5, welding the central tube 5 and the guide cloth 6 at a second angular position. The above operation is then repeated to weld the central tube 5 and the guide cloth 6 at a third or even more angular positions. In this embodiment, the lifting seat 9 corresponds one-to-one with the ultrasonic welder 8, and the lifting drive 10 corresponds one-to-one with the lifting seat 9. The lifting drive 10 can be a drive cylinder. Multiple ultrasonic welders 8 are arranged sequentially along the left-right direction. The specific structure of the ultrasonic welder 8 is prior art well known to those skilled in the art and will not be described in detail in this embodiment.

[0069] like Figure 1 , 3As shown, the forward and backward moving assembly may include a first moving seat 11, a second moving seat 12, a third moving seat 13, a fourth moving seat 14, a first moving cylinder 15, a second moving cylinder 16, a third moving cylinder 17, and a fourth moving cylinder 18.

[0070] The first movable seat 11 is slidably connected to the frame 1 in the front-back direction, and the second movable seat 12 is slidably connected to the first movable seat 11 in the front-back direction;

[0072] One end of the mounting bracket 7 is connected to the second movable seat 12, and the other end of the mounting bracket 7 is connected to the fourth movable seat 14;

[0073] The first movable cylinder 15 is connected to the frame 1 and connected to the first movable seat 11 and is used to drive the first movable seat 11 to move back and forth relative to the frame 1.

[0074] The second movable cylinder 16 is connected to the first movable seat 11 and connected to the second movable seat 12, and is used to drive the second movable seat 12 to move back and forth relative to the first movable seat 11;

[0075] The third moving cylinder 17 is connected to the frame 1 and connected to the third moving seat 13 and is used to drive the third moving seat 13 to move back and forth relative to the frame 1.

[0076] The fourth moving cylinder 18 is connected to the third moving seat 13 and connected to the fourth moving seat 14, and is used to drive the fourth moving seat 14 to move back and forth relative to the third moving seat 13. Specifically, when the first moving cylinder 15 drives the first moving seat 11 to move back and forth and the third moving cylinder 17 drives the third moving seat 13 to move back and forth, it can drive the mounting frame 7 to move back and forth. When the second moving cylinder 16 drives the second moving seat 12 to move back and forth and the fourth moving cylinder 18 drives the fourth moving seat 14 to move back and forth, it can also drive the mounting frame 7 to move back and forth, thereby driving the ultrasonic welder 8 to move back and forth above the central tube 5.

[0077] like Figure 1 , 3 As shown, the mounting frame 7 may include a crossbeam 19 and a connecting seat 20 corresponding to the lifting seat 9;

[0078] One end of the crossbeam 19 is connected to the second movable seat 12, and the other end of the crossbeam 19 is connected to the fourth movable seat 14;

[0079] The connecting seat 20 is connected to the crossbeam 19, and the lifting seat 9 is slidably connected to the corresponding connecting seat 20 in the up-down direction;

[0080] The lifting drive component 10 is connected to the corresponding connecting seat 20 and connected to the corresponding lifting seat 9, and is used to drive the corresponding lifting seat 9 to move up and down, thereby driving the corresponding ultrasonic welder 8 to move up and down; in this embodiment, the connecting seat 20 and the lifting seat 9 correspond one-to-one.

[0081] like Figure 1 , 2 As shown in Figure 4, the hosting component 2 includes at least one V-shaped block 21 connected to the frame 1, and the central tube 5 is used to place on the V-shaped block 21; in this embodiment, multiple V-shaped blocks 21 are arranged sequentially at intervals along the axial direction of the central tube 5.

[0082] like Figure 1 , 4 As shown in Figures 5 and 6, the tube clamping and rotating mechanism 3 may include a first moving component 22, a second moving component 23, a first top shaft 24, a second top shaft 25, a clamping drive mechanism, and a rotating drive mechanism.

[0083] The first moving component 22 and the second moving component 23 are slidably connected to the frame 1 along the axial direction of the central tube 5, respectively;

[0084] The first top shaft 24 is rotatably connected to the first moving component 22 and is located on one side of the central tube 5 on the hosting component 2;

[0085] The second top shaft 25 is rotatably connected to the second moving component 23 and is located on the other side of the central tube 5 on the hosting component 2;

[0086] The clamping drive mechanism is connected to the first moving component 22 and the second moving component 23 respectively. The clamping drive mechanism is used to drive the first moving component 22 to move toward the central tube 5, thereby driving the first top shaft 24 to move to abut one end of the central tube 5. The clamping drive mechanism is also used to drive the second moving component 23 to move toward the central tube 5, thereby driving the second top shaft 25 to move to abut the other end of the central tube 5, thereby causing the first top shaft 24 and the second top shaft 25 to clamp the central tube 5.

[0087] The rotary drive mechanism is connected to the first moving component 22. The rotary drive mechanism is connected to the first top shaft 24 and is used to drive the first top shaft 24 to rotate, thereby causing the central tube 5, which is clamped by the first top shaft 24 and the second top shaft 25, to rotate by an angle.

[0088] like Figure 4 , 5 As shown, the first moving component 22 may include a first slide 26, a first adjusting seat 27, and a first lifting cylinder 28;

[0089] The first slide block 26 is slidably connected to the frame 1 along the axial direction of the central tube 5;

[0090] The first lifting cylinder 28 is connected to the first slide 26, the first adjusting seat 27 is connected to the first lifting cylinder 28, and the first top shaft 24 is rotatably connected to the first adjusting seat 27. The first lifting cylinder 28 is used to drive the first adjusting seat 27 to move up and down so as to adjust the height position of the first top shaft 24.

[0091] The rotary drive mechanism is connected to the first adjusting seat 27 and connected to the first top shaft 24 and is used to drive the first top shaft 24 to rotate, thereby causing the central tube 5 clamped by the first top shaft 24 and the second top shaft 25 to rotate by an angle.

[0092] The second moving component 23 may include a second slide 29, a second adjusting seat 30, and a second lifting cylinder 31;

[0093] The second slide block 29 is slidably connected to the frame 1 along the axial direction of the central tube 5;

[0094] The second lifting cylinder 31 is connected to the second slide 29, the second adjusting seat 30 is connected to the second lifting cylinder 31, and the second top shaft 25 is rotatably connected to the second adjusting seat 30. The second lifting cylinder 31 is used to drive the second adjusting seat 30 to move up and down so as to adjust the height position of the second top shaft 25.

[0095] The clamping drive mechanism is connected to the first slide 26 and the second slide 29 respectively. The clamping drive mechanism is used to drive the first slide 26 to move toward the central tube 5, thereby driving the first top shaft 24 to move to abut one end of the central tube 5. The clamping drive mechanism is also used to drive the second slide 29 to move toward the central tube 5, thereby driving the second top shaft 25 to move to abut the other end of the central tube 5, so that the first top shaft 24 and the second top shaft 25 clamp the central tube 5. Specifically, the central tube 5 has two diameter specifications. When the large-diameter central tube 5 is placed on the V-block 21 in the support component 2, the center height of the central tube 5 is higher. When the small-diameter central tube 5 is placed on the V-block 21 in the support component 2, the center height of the central tube 5 is lower. Therefore, it is necessary to drive the first adjusting seat 27 up and down through the first lifting cylinder 28 to adjust the height position of the first top shaft 24, and it is necessary to drive the second adjusting seat 30 up and down through the second lifting cylinder 31 to adjust the height position of the second top shaft 25.

[0096] In this embodiment, the clamping drive mechanism includes a first clamping cylinder 32 and a second clamping cylinder 33. The first clamping cylinder 32 is connected to the frame 1 and to the first slide 26. The first clamping cylinder 32 drives the first slide 26 to move toward the central tube 5, thereby driving the first lifting cylinder 28, the first adjusting seat 27, and the first top shaft 24 to move toward the central tube 5 so that the first top shaft 24 moves to abut one end of the central tube 5. The second clamping cylinder 33 is connected to the frame 1 and to the second slide 29. The second clamping cylinder 33 drives the second slide 29 to move toward the central tube 5, thereby driving the second lifting cylinder 31, the second adjusting seat 30, and the second top shaft 25 to move toward the central tube 5 so that the second top shaft 25 moves to abut the other end of the central tube 5. The thrust of the first clamping cylinder 32 is different from the thrust of the second clamping cylinder 33. Specifically, driven by the thrust of the first clamping cylinder 32, the first top shaft 24 presses against one end of the central tube 5, and driven by the thrust of the second clamping cylinder 33, the second top shaft 25 presses against the other end of the central tube 5, thereby clamping the central tube 5. By setting the thrust of the first clamping cylinder 32 and the thrust of the second clamping cylinder 33 to different magnitudes, it is possible to ensure that the axial position of the central tube 5 is the same each time the first top shaft 24 and the second top shaft 25 clamp the central tube 5. Of course, in some embodiments, the clamping drive mechanism may also adopt the following structure: the clamping drive mechanism may include a drive motor, a bidirectional lead screw, a first transmission nut and a second transmission nut, the bidirectional lead screw is rotatably connected to the frame 1, the first transmission nut is connected to the first slide 26, the second transmission nut is connected to the second slide 29, the first threaded portion on the bidirectional lead screw is engaged with the first transmission nut, the second threaded portion on the bidirectional lead screw is engaged with the second transmission nut, the first threaded portion and the second threaded portion rotate in opposite directions, the drive motor is connected to the bidirectional lead screw and is used to drive the bidirectional lead screw to rotate, thereby causing the first slide 26 and the second slide 29 to move towards each other, so that the first top shaft 24 moves to abut one end of the central tube 5 and the second top shaft 25 moves to abut the other end of the central tube 5, thereby causing the first top shaft 24 and the second top shaft 25 to clamp the central tube 5.

[0097] like Figure 4 , 5As shown, the rotary drive mechanism may include a rotary motor 34, a drive wheel 35, a driven wheel 36, and a transmission belt 37. The rotary motor 34 is connected to the first adjusting seat 27, the drive wheel 35 is connected to the output shaft of the rotary motor 34, the driven wheel 36 is connected to the first top shaft 24, and the transmission belt 37 is connected to the drive wheel 35 and the driven wheel 36. When the rotary motor 34 drives the drive wheel 35 to rotate, it will drive the driven wheel 36 to rotate through the transmission belt 37, thereby driving the first top shaft 24 to rotate, and thus driving the central tube 5 clamped by the first top shaft 24 and the second top shaft 25 to rotate by an angle.

[0098] like Figure 4 , 5 As shown, the welding device for the central tube and the guide cloth may also include a controller and a laser sensor 38 for emitting a beam 40 to the central tube 5;

[0099] The laser sensor 38 is connected to the controller and is used to send a signal to the controller when the clamping and rotating mechanism 3 drives the central tube 5 to rotate so that the water outlet 39 on the central tube 5 is aligned with the beam 40 emitted by the laser sensor 38.

[0100] The controller is connected to the tube clamping and rotating mechanism 3 and is used to control the operation of the tube clamping and rotating mechanism 3 according to the signal sent by the laser sensor 38, so as to drive the central tube 5 to rotate to a suitable angle; specifically, the laser sensor 38 is connected to the frame 1, and the controller is at least connected to the rotary motor 34 in the tube clamping and rotating mechanism 3 and is used to control the operation of the rotary motor 34 according to the signal sent by the laser sensor 38, so as to drive the central tube 5 clamped by the first top shaft 24 and the second top shaft 25 to rotate to a suitable angle.

[0101] More specifically, the central tube 5 is provided with two outlet holes 39, which are 180° apart. When the ultrasonic welder 8 welds the guide cloth 6 onto the central tube 5, it should avoid having the outlet holes 39 on the central tube 5 directly facing the ultrasonic welder 8. This is because if the outlet holes 39 are directly facing the ultrasonic welder 8, the ultrasonic welder 8 will weld the guide cloth 6 onto the outlet holes 39 on the central tube 5, thus blocking part of the outlet holes 39 and reducing the water output efficiency. In this embodiment, the laser sensor 38 is used to emit a beam 40 vertically upward. The ultrasonic welder 8 is located directly above the central tube 5. When the clamping and rotating mechanism 3 drives the central tube 5 to rotate so that the outlet holes 39 on the central tube 5 are aligned with the beam 40 emitted by the laser sensor 38, the beam 40 emitted by the laser sensor 38 will pass through the outlet holes 39. At this time, the laser sensor 38 will trigger the generation of a signal and send the signal to the controller. When the controller receives a signal, it indicates that one of the drain holes 39 on the central tube 5 is vertically upward and the other is vertically downward. The upward-facing drain hole 39 is directly opposite the ultrasonic welder 8. Therefore, the controller needs to control the rotary motor 34 in the tube clamping mechanism 3 to rotate the central tube 5 by a suitable angle to prevent the drain hole 39 from directly facing the ultrasonic welder 8. The angle rotated by the central tube 5 cannot be 0° or a multiple of 180°. It is also important to note that when welding the central tube 5 and the guide cloth 6 at multiple angles, the drain hole 39 on the central tube 5 must always be kept out of direct contact with the ultrasonic welder 8. In this embodiment, the laser sensor 38 can be, but is not limited to, EX-L221, and the controller can be a PLC controller.

[0102] In summary, firstly, a central tube 5 is transported and placed on the hosting component 2. Then, the tube clamping and rotating mechanism 3 clamps the central tube 5 on the hosting component 2 and rotates the clamped central tube 5 by a certain angle. Then, a guide cloth 6 is pulled manually or by the traction mechanism 100 and overlapped on the central tube 5. Then, the welding mechanism 4 operates to press the guide cloth 6 overlapped on the central tube 5 onto the central tube 5 and performs ultrasonic welding on the guide cloth 6 and the central tube 5, thus welding the central tube 5 and the guide cloth 6 at the first angle position. Then, the welding mechanism 4 operates to release the pressure on the guide cloth 6 on the central tube 5. Then, the tube clamping and rotating mechanism 3 drives the central tube 5 to rotate by a certain angle. Then, the welding mechanism 4 operates again to press the guide cloth 6 onto the central tube 5 and perform ultrasonic welding on the guide cloth 6 and the central tube 5, thus welding the central tube 5 and the guide cloth 6 at the second angle position. The above operation is then repeated to weld the central tube 5 and the guide cloth 6 at a third or even more angular positions. This allows for welding of the central tube 5 and the guide cloth 6 at multiple angular positions, greatly improving the strength of the weld between the central tube 5 and the guide cloth 6, and thus preventing the guide cloth 6 from detaching from the central tube 5. After welding is completed, the clamping and rotating mechanism 3 releases the central tube 5 so that the central tube 5 is once again supported on the support member 2.
