Description

Technical Field

[0001] This application relates to the field of butterfly valves, and more particularly to a fully automatic sealing device for butterfly valves. Background Technology

[0002] A butterfly valve is a common type of valve, named for its shape resembling a butterfly wing. It consists of a disc-shaped valve body and a shaft fixed at the center of the valve body.

[0003] The working principle of a butterfly valve is to control the flow of the medium by rotating the valve body. When the valve body is fully open, the medium can pass through the central hole of the valve body without obstruction. When the valve body is fully closed, the disc of the valve body will completely fit against the valve seat, preventing the medium from passing through.

[0004] In order to increase the sealing performance of butterfly valves during production, a sealing membrane is usually applied to the outlet of the butterfly valve.

[0005] When sealing a butterfly valve, the operator usually manually covers the valve outlet with a diaphragm and uses tools to perform the sealing operation. However, during manual operation, there is a possibility that the sealing is incomplete or the diaphragm may fall off, which will affect the sealing effect. Summary of the Invention

[0006] In order to reduce the possibility of incomplete sealing or film peeling, which may affect the coating effect, this application provides a fully automatic sealing device with a butterfly valve.

[0007] The fully automatic sealing device for butterfly valves provided in this application adopts the following technical solution:

[0008] A fully automatic sealing device for butterfly valves includes a frame, on which a feeding mechanism, a placement tray, a film forming mechanism, and a discharging mechanism are mounted. The placement tray is rotatably mounted on the frame, and a drive assembly for rotating the placement tray is mounted on the frame. The feeding mechanism, film forming mechanism, and discharging mechanism are distributed along the circumference of the placement tray. The feeding mechanism is used to transport butterfly valves to the placement tray. The film forming mechanism is used to cut the film. A sealing device is provided between the film forming mechanism and the frame for sealing the cut film onto the butterfly valve. The discharging mechanism is used to collect the sealed butterfly valves.

[0009] By adopting the above technical solution, the butterfly valve is conveyed to the placement tray by the feeding mechanism. The drive component drives the butterfly valve to rotate on the frame, thereby rotating the butterfly valve to the bottom of the sealing device. The film forming mechanism cuts the film to the size to be sealed and moves it above the butterfly valve to be sealed under the drive of the sealing device. The sealing device seals the film at the opening of the butterfly valve to be sealed. Finally, the butterfly valve after filming is moved to the unloading mechanism by the rotation of the placement tray. The unloading mechanism unloads and collects the film. The entire filming process is carried out by equipment, reducing the possibility of incomplete filming or film detachment from the butterfly valve that may occur during manual filming, thus affecting the filming effect of the butterfly valve.

[0010] Optionally, the film-forming mechanism includes a film feeding device, a film pressing device, and a film cutting device. The film feeding device is mounted on the frame and is used to place the film roll. The film pressing device is mounted on the frame and is used to flatten the surface of the film. The film cutting device is located on the side of the frame opposite to the film feeding device of the film pressing device. The film cutting device includes a support platform, a mold, a cutter, and a driving component. The support platform is mounted on the frame, the mold is mounted on the support platform, and a heating element is provided between the support platform and the frame. The driving component is mounted on the frame, and the cutter is located at the bottom end of the driving component. The driving component drives the cutter to move up and down to cut the film. After the film is cut by the cutter, the film adheres to the cutter under the action of the heating element.

[0011] By adopting the above technical solution, when the film forming mechanism cuts the film, the film feeding device conveys the film. During the conveying process, the film is flattened by the film pressing device, making the film surface flat. When the film is conveyed between the support table and the mold, the drive component drives the cutter to slide downward. Through the action of the heating element and the cutter, the film is formed on the cutter, and the film is pre-cut into the required shape, which is convenient for subsequent film lamination on the butterfly valve.

[0012] Optionally, the sealing device includes a movable frame and a pulling member. The movable frame is slidably disposed on the frame along the radial direction of the placement tray. The driving member is disposed on the movable frame, and the pulling member is disposed on the frame. The pulling member drives the movable frame to slide on the frame, and the pulling member drives the film to move directly above the butterfly valve.

[0013] By adopting the above technical solution, after the film cutting device cuts the film, the pulling component pulls the moving frame to slide on the frame, so that the cutter and the film are directly above the outlet end of the butterfly valve. Then, the driving component drives the cutter and the film to slide downward, so that the film covers the butterfly valve. The pulling component and the driving component cover the cut film on the butterfly valve, thus placing the cut film at the sealing position of the butterfly valve.

[0014] Optionally, the film pressing device includes a lower film pressing roller, an upper film pressing roller, and an adjusting component. The lower film pressing roller is mounted on the frame, the adjusting component is mounted on the frame, and the upper film pressing roller is mounted on the adjusting component. There is a gap between the upper film pressing roller and the lower film pressing roller for the film to pass through. The adjusting component is used to drive the upper film pressing roller to move up and down.

[0015] By adopting the above technical solution, when the film pressing device rolls the film, the film passes through the pressing hole between the upper and lower pressing rollers. The upper pressing roller presses the film against the lower pressing roller. As the film is conveyed, the film is rolled in sequence, so that the film surface is relatively flat when sealing. The adjusting component adjusts the gap between the upper and lower pressing rollers to improve the rolling effect of the film.

[0016] Optionally, the frame is provided with a stamping device for secondary stamping of the film onto the butterfly valve. The stamping device is located between the moving frame and the unloading mechanism. The stamping device includes a welded part and a stamping part. The stamping part is disposed on the frame, and the welded part is disposed at the bottom end of the stamping part. The stamping part drives the welded part to rise and fall. The welded part is located directly above the butterfly valve placement position on the placement plate.

[0017] By adopting the above technical solution, after the driven component places the cut film on the butterfly valve, the drive assembly drives the butterfly valve to rotate below the stamping device. The stamping component drives the weldment to move downward, so that the weldment abuts the film downward, making the film make secondary contact with the sealing port of the butterfly valve. Under the high temperature of the weldment, the film is heat-bonded to the sealing port of the butterfly valve, thereby improving the film coating effect and reducing the possibility of the film falling off the butterfly valve.

[0018] Optionally, the feeding mechanism includes a clamping device, a feeding conveyor belt, and a feeding channel. The clamping device is mounted on the frame and located above the placement tray. The feeding conveyor belt is mounted on the frame and is used to drive the butterfly valve to feed the material. The clamping device slides along the placement tray toward the feeding conveyor belt. The feeding channel is located at the end of the feeding conveyor belt away from the placement tray.

[0019] By adopting the above technical solution, after the welding of the butterfly valve is completed, it is transported to the unloading device by the placement tray. The clamping device clamps the butterfly valve from the placement tray and places it on the unloading conveyor belt. The butterfly valve is transported by the transmission of the unloading conveyor belt. The unloading conveyor belt drives the butterfly valve to the unloading channel. The butterfly valve falls down from the unloading channel and is collected, thus completing the process of loading, coating and unloading the butterfly valve.

[0020] Optionally, a counting device is provided between the feeding channel and the frame. The counting device includes a counter, a partition plate, and a rotating component. The counter is mounted on the frame and located at the tail end of the feeding conveyor belt. The partition plate is rotatably mounted on the feeding channel, and its length direction intersects with the length direction of the feeding channel. The rotating component is mounted on the frame and electrically connected to the counter. The rotating component drives the partition plate to rotate. When the value of the counter reaches a set value, the rotating component drives the partition plate to rotate.

[0021] By adopting the above technical solution, when the butterfly valve is conveyed to the feeding conveyor belt and the feeding channel, the counter counts the number of butterfly valves passing through the tail end of the feeding conveyor belt. When the recorded value reaches a certain amount, the rotating part drives the partition plate to rotate on the feeding channel, causing the feeding port of the butterfly valve to shift, thereby batch packaging the butterfly valve at the feeding channel.

[0022] Optionally, the placement tray has a placement groove, which includes a first groove and a second groove. The first groove is used to place the inlet end of the butterfly valve, and the second groove is used to place the outlet end of the butterfly valve. A notch is provided between the first groove and the second groove, which is used to connect with the connection between the inlet end and the outlet end of the butterfly valve.

[0023] By adopting the above technical solution, when the butterfly valve is placed in the placement groove, the inlet end of the butterfly valve is placed in the first groove, the outlet end of the butterfly valve is placed in the second groove, and the connection between the inlet end and the outlet end of the butterfly valve is inserted into the notch, thereby inserting the butterfly valve into the placement groove, reducing the possibility of the butterfly valve shaking during the sealing process, and thus reducing the possibility of incomplete sealing or film detachment of the butterfly valve.

[0024] Optionally, the feeding mechanism includes a hopper, a conveyor belt, a vibrating plate, a feeding track, and a picking device. The hopper is mounted on the frame, the conveyor belt is mounted on the frame, one end of the conveyor belt is connected to the discharge port of the hopper, and the other end extends upward at an angle. The vibrating plate is mounted on the frame, and a feeding bin is mounted on the frame. One end of the feeding bin is connected to the upper end of the conveyor belt, and the other end extends above the vibrating plate. One end of the feeding track is mounted on the vibrating plate, and the other end is mounted on the frame and close to the placement plate. The picking device is mounted on the frame and clamps the butterfly valve located at the end of the feeding track and places it in the placement slot.

[0025] By adopting the above technical solution, workers place the butterfly valves that need to be sealed in the hopper. When the conveyor belt is conveying, the butterfly valves in the hopper fall downwards onto the conveyor belt. The butterfly valves are then conveyed upwards by the conveyor belt and transported to the feeding bin. From the feeding bin, the butterfly valves are transported to the vibrating plate, reducing the possibility of butterfly valves accumulating and clogging in the vibrating plate. The butterfly valves are then conveyed downwards one by one to the conveying track by the vibration of the vibrating plate, so that the butterfly valves are transported along the conveying track to the end of the conveying track. The butterfly valves at the end are placed in the placement slot under the clamping of the material picking device, thus completing the feeding and placement of the butterfly valves before film coating, which facilitates the subsequent film coating of the butterfly valves.

[0026] Optionally, the material handling device includes a first driving member, a sliding plate, a second driving member, and two grippers. The sliding plate is slidably disposed on the frame along the radial direction of the placement tray. The first driving member is disposed on the frame and drives the sliding plate to slide on the frame. A lifting plate is provided on the sliding plate. A lifting member is provided on the sliding plate to drive the lifting plate to slide in the vertical direction. The two grippers are distributed perpendicular to the material conveying track. There are two second driving members disposed on the lifting plate. The two first driving members correspond one-to-one with the two grippers and drive the grippers to clamp the butterfly valve.

[0027] By adopting the above technical solution, when the clamping device clamps the butterfly valve, the lifting component drives the lifting plate to slide downward on the sliding plate. When the gripper moves to the clamping position, the second driving component drives the gripper to clamp the butterfly valve. The lifting component then drives the lifting plate, gripper, and butterfly valve to move upward. The first driving component starts, driving the sliding plate to slide on the frame, thereby conveying the clamped butterfly valve to the top of the placement slot. The lifting component then drives the lifting plate, gripper, and butterfly valve to move downward, thereby placing the butterfly valve in the first and second grooves. The second driving component causes the gripper to clamp the butterfly valve, thus completing the loading of the butterfly valve from the conveying track to the placement tray.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The butterfly valve is conveyed to the placement tray by the feeding mechanism, and then the film is cut into the size to be coated by the film forming mechanism. The film is then sealed on the outlet end of the butterfly valve by the sealing device. Finally, the coated butterfly valve is unloaded by the unloading mechanism. This reduces the possibility of incomplete coating or film falling off due to manual coating of the butterfly valve, which may affect the coating effect.

[0030] 2. During the cutting process, the film is rolled by a pressing device to make the film surface smooth, reducing the possibility that unevenness of the film surface will affect the coating effect;

[0031] 3. When placing the butterfly valve on the placement tray, the inlet end of the butterfly valve is placed in the first groove, the outlet end is placed in the second groove, and the connection between the inlet end and the outlet end is inserted into the notch, so that the butterfly valve can be placed more stably on the placement tray, which is convenient for subsequent film covering.

[0041] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0042] This application discloses a fully automatic sealing device for butterfly valves. (Refer to...) Figure 1 The butterfly valve 14 includes an inlet 141, an outlet 142, and a connecting part 143, with the connecting part 143 located between the inlet 142 and the outlet 142.

[0043] Reference Figure 2 and Figure 3 The system includes a frame 1, on which a feeding mechanism 2, a placement tray 11, a film forming mechanism 3, and a discharging mechanism 5 are mounted. The placement tray 11 is rotatably mounted on the frame 1. A drive assembly 12 for rotating the placement tray 11 is mounted on the frame 1. The feeding mechanism 2, the film forming mechanism 3, and the discharging mechanism 5 are distributed along the circumference of the placement tray 11. A sealing device 34 for sealing the cut film on a butterfly valve 14 is installed between the molding mechanism and the frame 1.

[0044] Reference Figure 3 and Figure 4The placement tray 11 has a placement groove 13, which has multiple grooves along the circumference of the placement tray 11. The placement groove 13 includes a first groove 131 and a second groove 132. The first groove 131 is used to place the inlet 141 of the butterfly valve 1414, and the second groove 132 is used to place the outlet 142 of the butterfly valve 1414. A notch 133 is provided between the first groove 131 and the second groove 132. The notch 133 is used to insert into the connection part 143 between the inlet 141 of the butterfly valve 1414 and the outlet 142 of the butterfly valve 1414. By inserting and placing the butterfly valve 14 through the first groove 131, the notch 133 and the second groove 132, the shaking of the butterfly valve 14 during the sealing process is reduced, which may affect the sealing effect of the butterfly valve 14.

[0045] The drive assembly 12 includes a drive motor, which is a servo motor. The drive motor is mounted on the frame 1 and is connected to the placement tray 11. The drive motor drives the placement tray 11 to rotate on the frame 1, which facilitates the loading, sealing and unloading of the butterfly valve 14.

[0046] Reference Figure 2 and Figure 3 The feeding mechanism 2 includes a hopper 21, a conveyor belt 22, a vibrating plate 23, a conveying track 24, and a material handling device 25. The hopper 21 is mounted on the frame 1, and the conveyor belt 22 is driven and mounted on the frame 1. One end of the conveyor belt 22 extends to the discharge port of the hopper 21, and the other end extends upward at an angle. A baffle plate 231 is installed on the conveyor belt 22. The baffle plate 231 extends perpendicular to the length direction of the conveyor belt 22. Multiple baffle plates 231 are distributed along the length direction of the conveyor belt 22, and a stacking groove 232 is formed between adjacent baffle plates 231. When the butterfly valve 14 is conveying, it is stacked in the stacking groove 232.

[0047] A feeding bin 233 is installed between the upper end of the conveyor belt 22 and the frame 1. The feeding bin 233 extends downward at an incline perpendicular to the length of the conveyor belt 22 between the frame 1 and the conveyor belt 22.

One end of the conveying track 24 is installed at the discharge port of the vibrating plate 23, and the other end extends downward at an incline. The tail end of the conveying track 24 is close to the placement plate 11. The butterfly valve 14 is fed through the conveyor belt 22, the vibrating plate 23 and the conveying track 24, reducing the difficulty and labor intensity of manual feeding.

[0048] Reference Figure 2 and Figure 3The material handling device 25 includes a first driving member 251, a sliding plate 254, a second driving member 252, and two grippers 253.

The second driving component 252 includes a second driving cylinder. There are two second driving cylinders installed. The two second driving cylinders correspond one-to-one with the two grippers 253. The lifting cylinder drives the lifting plate 256 to slide downward.

[0049] Reference Figure 3 and Figure 4 The second drive cylinder drives the gripper 253 to clamp the butterfly valve 14. The lifting cylinder drives the lifting plate 256, the second drive cylinder, and the two grippers 253 to slide upward. Then the first drive cylinder is activated, which drives the sliding plate 254 to slide on the frame 1, so that the clamped butterfly valve 14 moves to the top of the placement slot 13. The lifting cylinder is activated, which drives the clamped butterfly valve 14 to move downward, so that the inlet 141 end of the butterfly valve 14 is located in the first groove 131, the outlet 142 end is located in the second groove 132, and the connection between the inlet 141 end and the outlet 142 end of the butterfly valve 14 is inserted into the notch 133. Then the second drive cylinder is activated, which causes the gripper 253 to release the gripper 253, so that the butterfly valve 14 is placed in the first groove 131, the second groove 132, and the notch 133.

[0050] Reference Figure 2 and Figure 5 The film forming mechanism 3 includes a film feeding device 31, a film pressing device 32, and a film cutting device 33. The film feeding device 31 includes a film roller 311 and a guide roller 312. The film roller 311 is rotatably mounted on the frame 1 and can be detachably mounted on the frame 1. Film baffles 313 are installed on both ends of the film roller 311. Observation ports 314 are provided on the film baffles 313. Multiple observation ports 314 are distributed around the circumference of the film baffles 313. The usage status of the film on the film roller 311 can be observed through the observation ports 314, which facilitates timely replacement of the film roller 311. The guide roller 312 is rotatably mounted on the frame 1. The film passes under the guide roller 312. The film is conveyed by the film roller 311 and the guide roller 312, reducing the possibility of insufficient film during lamination.

[0051] Reference Figure 6The film pressing device 32 includes an upper film pressing roller 322, a lower film pressing roller 321, and an adjusting assembly 323. Both the upper and lower film pressing rollers 322 and 321 are rotatably mounted on the frame 1. A film pressing opening for the film to pass through is located between the upper and lower film pressing rollers 322 and 321. The adjusting assembly 323 includes an adjusting block 3233, an adjusting rod 3231, and an adjusting spring 3232. The adjusting block 3233 is slidably mounted on the frame 1 in the vertical direction. The upper film pressing roller 322 is rotatably mounted on the adjusting block 3233. The adjusting rod 3231 is threaded onto the adjusting block. The adjusting rod 3231 is vertically installed on the frame 1. A fixing plate 3234 is installed at the bottom of the adjusting rod 3231. One end of the adjusting spring 3232 is fixedly installed on the lower surface of the fixing plate 3234, and the other end is fixedly installed on the upper surface of the adjusting block 3233. When the adjusting spring 3232 is in a compressed state, the adjusting block 3233 slides downward under the abutment of the adjusting spring 3232 and abuts the film against the lower pressure roller 321, thereby squeezing the surface of the film and reducing the possibility of a rough film surface.

[0052] The sealing device 34 includes a movable frame 341 and a pulling member 342. The movable frame 341 is horizontally mounted on the frame 1 along the radial direction of the placement tray 11.

A heating element 335 is mounted on the frame 1, and the heating element 335 is located directly below the support platform 331. The mold 332 is mounted on the upper surface of the support platform 331. The drive component 334 includes a drive cylinder, which is mounted on the movable frame 341 and operates vertically. The cutter 333 is installed on the piston rod of the drive cylinder and located directly below the piston rod. The drive cylinder drives the cutter 333 to move vertically downward. After passing through the cutting hole on the mold 332, the cutter 333 contacts the film and cuts the film downward, then abuts against the heating element 335. The film adheres to the cutter 333 under the heating of the heating element 335. Then the drive cylinder drives the cutter 333 and the film upward, thereby bringing the cut film above the mold 332.

[0054] Reference Figure 6 and Figure 7After the cylinder drives the cutter 333 to cut and adhere the film in the vertical direction, the cylinder drives the cutter 333 and the film to slide upward. Then, the cylinder pulls the moving frame 341 in the horizontal direction, so that the moving frame 341 drives the cutter 333 to slide directly above the sealing port of the butterfly valve 14. Then, the cylinder drives the cutter 333 to move downward, sealing the film adhered to the cutter 333 at the sealing port of the butterfly valve 14. After the film is sealed on the butterfly valve 14, the drive motor drives the placement tray 11 to rotate on the frame 1.

[0055] Reference Figure 7 A stamping device 4 for secondary stamping of the diaphragm onto the butterfly valve 14 is installed on the frame 1. The stamping device 4 includes a weldment 42 and a stamping component 41. The stamping component 41 includes a stamping cylinder, which is installed on the frame 1 and in a vertical direction. The weldment 42 is installed on the piston rod of the stamping cylinder. When the butterfly valve 14 with the diaphragm rotates to directly below the stamping cylinder, the stamping cylinder drives the weldment 42 to move downward in the vertical direction. The weldment 42 presses the diaphragm against the butterfly valve 14. Through the high temperature of the weldment 42, the diaphragm is heat-bonded to the butterfly valve 14, thereby stably sealing the diaphragm on the butterfly valve 14 and reducing the possibility of the diaphragm detaching from the butterfly valve 14.

[0056] The feeding mechanism 5 includes a clamping device 51, a feeding conveyor belt 52, and a feeding channel 53. The feeding conveyor belt 52 is driven and mounted on the frame 1. The length direction of the feeding conveyor belt 52 is consistent with the radial direction of the placement tray 11. The feeding channel 53 is mounted on the frame 1. One end of the feeding channel 53 is installed on the end of the feeding conveyor belt 52 away from the placement tray 11, and the other end is inclined downward and extends away from the feeding conveyor belt 52.

[0057] Reference Figure 7The clamping device 51 includes a third driving member 512, a sliding plate 511, a fourth driving member 513, and two grippers 253. The sliding plate 511 is slidably mounted on the frame 1 along the direction of the placement tray 11 toward the unloading conveyor belt 52. The third driving member 512 includes a third driving cylinder, which is mounted on the frame 1. The third driving cylinder drives the sliding plate 511 to slide on the frame 1. A lifting block 514 that slides vertically and a lifting cylinder are mounted on the sliding plate 511. The lifting cylinder is located above the lifting block 514 and drives the lifting block 514 to slide vertically. The two grippers 253 are distributed perpendicular to the unloading conveyor belt 52. The fourth driving member 513 includes a fourth driving cylinder. Installed on the lifting block 514, there are two fourth drive cylinders, each corresponding to one of the two grippers 253. The fourth drive cylinder drives the grippers 253 to hold the butterfly valve 14 after it has been coated. When the grippers 253 hold the butterfly valve 14, the lifting cylinder drives the lifting block 514 to move upward. Then, the third drive cylinder drives the sliding plate 511 to slide on the frame 1, thereby driving the butterfly valve 14 to slide above the unloading conveyor belt 22. Then, the fourth drive cylinder drives the grippers 253 to release the butterfly valve 14, causing the butterfly valve 14 to fall onto the unloading conveyor belt 52. The butterfly valve 14 is conveyed by the unloading conveyor belt 52 to the unloading channel 53 and is conveyed downward along the unloading channel 53 and collected.

[0058] Reference Figure 7 and Figure 8 A counting device 54 is installed between the frame 1 and the feeding channel 53. The counting device 54 includes a counter 541, a partition plate 543, and a rotating component 542. The counter 541 is mounted on the frame 1 and is located between the feeding conveyor belt 52 and the feeding channel 53. The partition plate 543 is rotatably mounted on the feeding channel 53, and its length direction intersects with the length direction of the feeding channel 53. The rotating component 542 includes a controller 5421 and a rotating motor 5422. The rotating motor 5422 is mounted on the feeding channel 53 and is located below the feeding channel 53. The rotating motor 5422 is driven by the partition plate 543. The controller 5421 is installed on the frame 1. The counter 541 is electrically connected to the controller 5421, and the controller 5421 is electrically connected to the rotating motor 5422. When the accumulated value in the counter 541 reaches the preset value in the controller 5421, the value recorded by the counter 541 is reset. At the same time, the controller 5421 controls the rotating motor 5422 to start. The rotating motor 5422 drives the partition plate 543 to rotate, so that the butterfly valve 14 performs batch packaging at the set value of the controller 5421 installed at the feeding channel 53.

[0059] The implementation principle of the fully automatic sealing device for butterfly valves in this application embodiment is as follows:

[0060] When sealing the butterfly valve 14, the operator pours the butterfly valve 14 into the hopper 21. The conveyor belt 22 conveys it on the frame 1. The butterfly valve 14 that falls from the outlet of the hopper 21 accumulates in the accumulation trough 232. The conveyor belt 22 drives the butterfly valve 14 to the feeding bin 233. The butterfly valve 14 falls down from the feeding bin 233 into the vibrating plate 23. Through the feeding of the vibrating plate 23, the butterfly valve 14 rolls down the conveying track to the end of the conveying track 24.

[0061] When the butterfly valve 14 is at the end of the conveying track 24, the lifting cylinder is activated, which drives the lifting plate 256 to move downward. When the gripper 253 approaches the butterfly valve 14, the second drive cylinder is activated, which causes the gripper 253 to clamp the butterfly valve 14. Then the lifting cylinder is activated again, which drives the lifting plate 256 to move upward. When the butterfly valve 14 moves away from the conveying track 24, the first drive cylinder is activated, which drives the sliding plate 254 to slide on the frame 1 toward the placement tray 11, thereby driving the butterfly valve 14 to slide above the placement groove 13 on the placement tray 11. The lifting cylinder is activated, which drives the butterfly valve 14 to move downward, so that the inlet 141 end of the butterfly valve 14 is located in the first groove 131 and the outlet 142 end is located in the second groove 132, thereby loading the butterfly valve 14 onto the placement tray 11.

[0062] During the feeding process of butterfly valve 14, film roller 311 rotates, and film passes sequentially from below guide roller 312 and between support platform 331 and mold 332. When film is at mold 332 and support platform 331, drive cylinder is activated. Cutter 333 moves downward and passes through mold 332 under the drive cylinder, bringing film abutting against heating element 335 below support platform 331. Under the action of heating element 335 and cutter 333, film adheres to cutter 333. Drive cylinder moves cutter 333 upward, pull cylinder is activated, and moving frame 341 moves towards placement tray 11. When cutter 333 moves to directly above second groove 132, drive cylinder is activated, driving cylinder to push cutter 333 downward, so that film on cutter 333 adheres to the sealing port of butterfly valve 14.

[0063] After the film adheres to the butterfly valve 14, the drive motor drives the placement plate 11 to rotate, so that the butterfly valve 14 with the film adhered rotates to the bottom of the stamping device 4.

[0064] The stamping cylinder drives the weldment 42 to move downward, so that the weldment 42 comes into contact with the diaphragm on the butterfly valve 14. Through the high temperature of the weldment 42, the diaphragm is hot-bonded to the butterfly valve 14, reducing the possibility of the diaphragm falling off the butterfly valve 14.

[0065] The sealed butterfly valve 14 rotates on the frame 1 along with the placement tray 11 to the unloading device. The lifting cylinder drives the lifting block 514 and the gripper 253 to slide downward. The fourth drive cylinder drives the gripper 253 to clamp the butterfly valve 14. Then, the lifting cylinder drives the butterfly valve 14 to slide upward. The third drive cylinder drives the translation plate to slide on the frame 1 to the unloading conveyor belt 52. The butterfly valve 14 is conveyed away from the placement tray 11 on the unloading conveyor belt 52 and is conveyed downward through the unloading channel 53 and collected.

[0066] When the value recorded by counter 541 reaches the preset value in controller 5421, controller 5421 controls the rotation motor 5422 to start, driving the separator 543 to rotate on the feeding channel 53, so that the butterfly valve 14 can perform batch packaging according to the set value after the sealing is completed.

[0067] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
