Description

Technical Field

[0001] This utility model relates to a diaphragm sealing and cutting synchronous mechanism. Background Technology

[0002] Currently, membrane cutting and stacking machines are used in the RO membrane production process to cut membrane sheets, fold membrane sheets, and stack folded membrane sheets with grids. Before cutting and folding the membrane sheets, ultrasonic welding and edge sealing are required. During edge sealing, longitudinal edge sealing is performed on the left and right sides of the membrane sheet, and transverse edge sealing is performed on the membrane sheet at intervals along the width direction. For example, in Chinese patent CN220198589U, a first ultrasonic welding mechanism and a second ultrasonic welding mechanism are used to perform longitudinal edge sealing on the left and right sides of the membrane sheet, and a third ultrasonic welding mechanism is used to perform transverse edge sealing on the membrane sheet. After the diaphragm is horizontally sealed, it needs to be cut to a predetermined length. However, in the prior art, the horizontal sealing and cutting of the diaphragm cannot be completed simultaneously in one station. The diaphragm needs to be horizontally sealed first and then cut in the next station. The horizontal sealing and cutting are carried out separately, which affects the processing cycle of horizontal sealing and cutting of the diaphragm and reduces the efficiency of horizontal sealing and cutting of the diaphragm.

During the synchronous movement of the ultrasonic welder, film pressing mechanism, and cutting mechanism, the ultrasonic welder is located on one side of the diaphragm and abuts against one side surface of the diaphragm, and the film pressing mechanism is located on the other side of the diaphragm and abuts against the other side surface of the diaphragm. The film pressing mechanism can press the diaphragm onto the ultrasonic welder, thereby enabling the ultrasonic welder to perform ultrasonic welding on the diaphragm to achieve lateral sealing. At the same time as lateral sealing, the cutting mechanism also moves synchronously along the width direction of the diaphragm and cuts the diaphragm along the width direction, thereby cutting the diaphragm to a predetermined length. Therefore, the diaphragm sealing and cutting synchronization mechanism of this embodiment can simultaneously complete the lateral sealing and cutting of the diaphragm in one station, optimizing the processing cycle of lateral sealing and cutting of the diaphragm, thereby improving the efficiency of lateral sealing and cutting of the diaphragm.

[0061] 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.

[0062] like Figures 1-5 As shown, a film sealing and cutting synchronous mechanism includes a frame 1, a moving mechanism, an ultrasonic welder 2, a film pressing mechanism 3, and a cutting mechanism 4.

[0063] The ultrasonic welder 2, the film pressing mechanism 3, and the cutting mechanism 4 are all connected to the moving mechanism;

[0064] The moving mechanism is connected to the frame 1 and is used to drive the ultrasonic welder 2, the film pressing mechanism 3 and the cutting mechanism 4 to move synchronously along the width direction of the diaphragm 5.

[0065] When the ultrasonic welder 2 moves along the width direction of the diaphragm 5, it is located on one side of the diaphragm 5 and is used to abut against one side surface of the diaphragm 5 in order to perform ultrasonic welding and sealing on the edge of the diaphragm 5.

[0066] When the pressing mechanism 3 moves along the width direction of the diaphragm 5, it is located on the other side of the diaphragm 5 and is used to abut against the other side surface of the diaphragm 5 and press the diaphragm 5 onto the ultrasonic welder 2;

[0067] When the cutting mechanism 4 moves along the width direction of the diaphragm 5, it is used to cut the diaphragm 5 along the width direction of the diaphragm 5. Specifically, when it is necessary to perform transverse edge sealing on the diaphragm 5, the diaphragm 5 is first stopped from moving forward. Then, the moving mechanism drives the ultrasonic welder 2, the pressing mechanism 3, and the cutting mechanism 4 to move synchronously along the width direction of the diaphragm 5. During the synchronous movement of the ultrasonic welder 2, the pressing mechanism 3, and the cutting mechanism 4, the ultrasonic welder 2 is located on one side of the diaphragm 5 and abuts against one side surface of the diaphragm 5, and the pressing mechanism 3 is located on the other side of the diaphragm 5 and abuts against the other side surface of the diaphragm 5. The pressing mechanism 3 can press the diaphragm 5 onto the ultrasonic welder 2, thereby enabling the ultrasonic welder 2 to perform ultrasonic welding on the diaphragm 5 to achieve transverse edge sealing. While the lateral edge sealing is being performed, the cutting mechanism 4 also moves synchronously along the width direction of the film 5 and cuts the film 5 along the width direction of the film 5, thereby cutting the film 5 into a predetermined length. Therefore, the film edge sealing and cutting synchronization mechanism of this application embodiment can complete the lateral edge sealing and cutting of the film 5 in one station, optimize the processing rhythm of the film 5 during lateral edge sealing and cutting, and thus improve the efficiency of lateral edge sealing and cutting of the film 5.

[0071] The pressing mechanism 3 is connected to the second movable seat 7, and both the second movable seat 7 and the pressing mechanism 3 are located on the other side of the diaphragm 5.

[0072] The cutting mechanism 4 is connected to either the first movable seat 6 or the second movable seat 7;

[0073] The driving mechanism is connected to the first movable seat 6 and the second movable seat 7 respectively and is used to drive the first movable seat 6 and the second movable seat 7 to move synchronously along the width direction of the diaphragm 5, thereby driving the ultrasonic welder 2, the film pressing mechanism 3 and the cutting mechanism 4 to move synchronously along the width direction of the diaphragm 5.

[0074] like Figures 1-5 As shown, both the first movable seat 6 and the second movable seat 7 are slidably connected to the frame 1 along the width direction of the diaphragm 5;

[0075] The drive mechanism may include a first linear module 8, a second linear module 9, a drive motor 10, and a transmission shaft 11;

[0076] The first linear module 8 is connected to the frame 1 and is connected to the first movable seat 6;

[0077] The second linear module 9 is connected to the frame 1 and is connected to the second movable seat 7;

[0078] The first linear module 8 and the second linear module 9 are connected by the drive shaft 11.

[0079] The drive motor 10 is connected to the first linear module 8 and is used to drive the first linear module 8 to move, thereby driving the second linear module 9 to move synchronously through the transmission shaft 11, thereby driving the first moving seat 6 and the second moving seat 7 to move synchronously; in this embodiment, both the first linear module 8 and the second linear module 9 can be synchronous belt type linear modules.

[0080] like Figures 2-5 As shown, the cutting mechanism 4 may include a cutter 12, a cutter holder 13, and a cutting cylinder 14;

[0081] The cutter 12 is connected to the cutter holder 13;

[0082] The blade holder 13 is connected to the cutting cylinder 14;

[0083] The cutting cylinder 14 is connected to either the first movable seat 6 or the second movable seat 7. The driving mechanism is used to drive the cutting cylinder 14 and the cutter 12 on the cutter holder 13 to move along the width direction of the film 5 when driving the first movable seat 6 and the second movable seat 7 to move synchronously along the width direction of the film 5.

[0084] The cutting cylinder 14 is used to drive the blade holder 13 and the cutter 12 to move toward the diaphragm 5 so that the cutter 12 contacts the diaphragm 5 and cuts the diaphragm 5 when moving along the width direction of the diaphragm 5. The cutting cylinder 14 is also used to drive the blade holder 13 and the cutter 12 to move away from the diaphragm 5 so that the cutter 12 does not contact the diaphragm 5 when moving along the width direction of the diaphragm 5.

[0085] like Figures 1-5 As shown, the pressing mechanism 3 may include a pressing roller 15, a roller seat 16, and a pressing cylinder 17;

[0086] The pressure roller 15 is rotatably connected to the wheel seat 16;

[0087] The wheel seat 16 is connected to the clamping cylinder 17;

[0088] The pressing cylinder 17 is connected to the second movable seat 7, and the driving mechanism is used to drive the pressing cylinder 17 and the pressure roller 15 on the wheel seat 16 to move along the width direction of the diaphragm 5 when driving the second movable seat 7 to move along the width direction of the diaphragm 5.

[0089] The clamping cylinder 17 is used to drive the wheel seat 16 and the pressure roller 15 to move toward the diaphragm 5 so that the pressure roller 15 abuts against the diaphragm 5 and presses the diaphragm 5 onto the ultrasonic welder 2 when moving along the width direction of the diaphragm 5. The clamping cylinder 17 is also used to drive the wheel seat 16 and the pressure roller 15 to move away from the diaphragm 5 so that the pressure roller 15 does not abut against the diaphragm 5 when moving along the width direction of the diaphragm 5.

[0090] In this embodiment, the first movable seat 6 and the ultrasonic welder 2 are located on the lower side of the diaphragm 5, the second movable seat 7 and the pressing mechanism 3 are located on the upper side of the diaphragm 5, and the cutting mechanism 4 is connected to the first movable seat 6 and located on the lower side of the diaphragm 5. When it is necessary to perform lateral edge sealing on the diaphragm 5, the diaphragm 5 is first stopped from moving forward. Then, the cutting cylinder 14 drives the knife holder 13 and the cutter 12 to move upward toward the diaphragm 5 into position. The pressing cylinder 17 drives the wheel holder 16 and the pressure roller 15 to move downward toward the diaphragm 5 into position. Then, the driving mechanism drives the first moving seat 6 and the second moving seat 7 to move synchronously along the width direction of the diaphragm 5, thereby driving the ultrasonic welder 2, the pressure roller 15 in the pressing mechanism 3 and the cutter 12 in the cutting mechanism 4 to move synchronously along the width direction of the diaphragm 5. During the synchronous movement, the pressure roller 15 abuts against the upper surface of the diaphragm 5 and presses the diaphragm 5 onto the ultrasonic welder 2. The ultrasonic welder 2 abuts against the lower surface of the diaphragm 5 and performs ultrasonic welding edge sealing on the diaphragm 5. The cutter 12 cuts the diaphragm 5 along the width direction of the diaphragm 5. After the lateral sealing and cutting are completed, the cutting cylinder 14 drives the blade holder 13 and the cutter 12 to move downwards away from the diaphragm 5 and into position. The pressing cylinder 17 drives the wheel holder 16 and the pressure roller 15 to move upwards away from the diaphragm 5 and into position. Then, the driving mechanism drives the first moving seat 6 and the second moving seat 7 to move synchronously back to the initial position along the width direction of the diaphragm 5. This, in turn, drives the ultrasonic welder 2, the pressure roller 15 in the film pressing mechanism 3, and the cutter 12 in the cutting mechanism 4 to move synchronously back to the initial position along the width direction of the diaphragm 5. During the process of returning to the initial position, the cutter 12 does not contact the diaphragm 5, and the pressure roller 15 does not abut against the diaphragm 5. In this embodiment, the cutting cylinder 14 in the cutting mechanism 4 is connected to the first moving seat 6, and the pressing cylinder 17 in the film pressing mechanism 3 is connected to the second moving seat 7.

[0091] like Figure 2 , 4 As shown in Figure 5, two ultrasonic welders 2 are connected to the first movable seat 6, and two pressing mechanisms 3 are connected to the second movable seat 7. The pressing mechanism 3 corresponds one-to-one with the ultrasonic welder 2 and is used to press the diaphragm 5 onto the corresponding ultrasonic welder 2 when it moves along the width direction of the diaphragm 5.

[0092] When the cutting mechanism 4 moves along the width direction of the diaphragm 5, it is used to cut the diaphragm 5 between the two ultrasonic welders 2; specifically, the blade in the cutting mechanism 4 is used to cut the diaphragm 5 along the width direction of the diaphragm 5 between the two ultrasonic welders 2, and the pressure roller 15 in the pressing mechanism 3 is used to press the diaphragm 5 onto the corresponding ultrasonic welder 2.

[0093] like Figures 1-6 As shown, the film sealing and cutting synchronous mechanism also includes a clamping mechanism;

[0094] The clamping mechanism is provided with a clamping channel through which the diaphragm 5 passes. The clamping mechanism is connected to the frame 1 and is used to clamp the diaphragm 5 that passes through the clamping channel.

[0095] When the ultrasonic welder 2 moves along the width direction of the diaphragm 5, it is used to abut against one side surface of the clamped diaphragm 5 in order to perform ultrasonic welding to seal the edge of the clamped diaphragm 5.

[0096] When the pressing mechanism 3 moves along the width direction of the diaphragm 5, it abuts against the other side surface of the clamped diaphragm 5 and presses the clamped diaphragm 5 onto the ultrasonic welder 2.

[0097] When the cutting mechanism 4 moves along the width direction of the diaphragm 5, it is used to cut the clamped diaphragm 5 along the width direction of the diaphragm 5. In this embodiment, the diaphragm 5 passes through the clamping channel. When it is necessary to perform transverse edge sealing on the diaphragm 5, the diaphragm 5 is first stopped from moving forward. Then, the clamping mechanism clamps the diaphragm 5 that has passed through the clamping channel. Then, the moving mechanism drives the ultrasonic welder 2, the film pressing mechanism 3 and the cutting mechanism 4 to move synchronously along the width direction of the diaphragm 5 so as to perform transverse ultrasonic welding edge sealing and cutting on the diaphragm 5 simultaneously.

[0098] like Figures 1-6 As shown, the clamping mechanism may include a first clamping plate 18, a second clamping plate 19, a first clamping drive assembly, and a second clamping drive assembly;

[0099] The first clamping plate 18 and the second clamping plate 19 are slidably connected to the frame 1, and the clamping channel is provided between the first clamping plate 18 and the second clamping plate 19;

[0100] The first clamping drive assembly is connected to the frame 1 and to the first clamping plate 18. The second clamping drive assembly is connected to the frame 1 and to the second clamping plate 19. The first clamping drive assembly is used to drive the first clamping plate 18 to move toward the diaphragm 5 in the clamping channel, and the second clamping drive assembly is used to drive the second clamping plate 19 to move toward the diaphragm 5 in the clamping channel so that the first clamping plate 18 and the second clamping plate 19 clamp the diaphragm 5. Specifically, the first clamping drive assembly is also used to drive the first clamping plate 18 to move away from the diaphragm 5 in the clamping channel, and the second clamping drive assembly is also used to drive the second clamping plate 19 to move away from the diaphragm 5 in the clamping channel so that the first clamping plate 18 and the second clamping plate 19 release the diaphragm 5.

[0101] like Figures 1-6 As shown, the first clamping plate 18 is located between the two ultrasonic welders 2, and the second clamping plate 19 is located between the two pressing mechanisms 3. The first clamping plate 18 is slidably connected to the frame 1 in the vertical direction and is located below the diaphragm 5. The second clamping plate 19 is slidably connected to the frame 1 in the vertical direction and is located above the diaphragm 5.

[0102] The first clamping drive assembly includes a first left cylinder 20 and a first right cylinder 21.

[0103] The first left cylinder 20 is connected to the frame 1 and to the left end of the first clamping plate 18 and is used to drive the left end of the first clamping plate 18 to move up and down.

[0104] The first right cylinder 21 is connected to the frame 1 and connected to the right end of the first clamping plate 18 and is used to drive the right end of the first clamping plate 18 to move up and down.

[0105] The second clamping drive assembly includes a second left cylinder 22 and a second right cylinder 23.

[0106] The second left cylinder 22 is connected to the frame 1 and to the left end of the second clamping plate 19 and is used to drive the left end of the second clamping plate 19 to move up and down.

[0107] The second right cylinder 23 is connected to the frame 1 and connected to the right end of the second clamping plate 19, and is used to drive the right end of the second clamping plate 19 to move up and down.

[0108] Specifically, when it is necessary to clamp the diaphragm 5, the first left cylinder 20 drives the left end of the first clamping plate 18 to move upward, the first right cylinder 21 drives the right end of the first clamping plate 18 to move upward, the second left cylinder 22 drives the left end of the second clamping plate 19 to move downward, and the second right cylinder 23 drives the right end of the second clamping plate 19 to move downward, thereby causing the first clamping plate 18 and the second clamping plate 19 to clamp the diaphragm 5 in the clamping channel.

[0109] In summary, when it is necessary to perform transverse edge sealing on the diaphragm 5, the diaphragm 5 is first stopped from moving forward. Then, the moving mechanism drives the ultrasonic welder 2, the film pressing mechanism 3, and the cutting mechanism 4 to move synchronously along the width direction of the diaphragm 5. During the synchronous movement of the ultrasonic welder 2, the film pressing mechanism 3, and the cutting mechanism 4, the ultrasonic welder 2 is located on one side of the diaphragm 5 and abuts against one side surface of the diaphragm 5, and the film pressing mechanism 3 is located on the other side of the diaphragm 5 and abuts against the other side surface of the diaphragm 5. The film pressing mechanism 3 can press the diaphragm 5 onto the ultrasonic welder 2, thereby enabling the ultrasonic welder 2 to perform ultrasonic welding on the diaphragm 5 to achieve transverse edge sealing. While the lateral edge sealing is being performed, the cutting mechanism 4 also moves synchronously along the width direction of the film 5 and cuts the film 5 along the width direction of the film 5, thereby cutting the film 5 into a predetermined length. Therefore, the film edge sealing and cutting synchronization mechanism of this application embodiment can complete the lateral edge sealing and cutting of the film 5 in one station, optimize the processing rhythm of the film 5 during lateral edge sealing and cutting, and thus improve the efficiency of lateral edge sealing and cutting of the film 5.
