Description

Technical Field

[0001] This disclosure relates to the field of filling technology, and in particular to a three-way valve filling device and a three-way valve filling machine. Background Technology

[0002] Modern reagent filling generally uses filling machines, which greatly improves dispensing speed and accuracy. For test tubes requiring capping, machine capping reduces labor intensity and provides a better tightening effect. A filling machine mainly consists of a tube feeding unit, a filling unit, and a capping unit. The filling and capping rates are the main limiting factors for the overall filling speed of the production line. The filling unit primarily uses a rotary table method, where processing occurs at multiple stations on a disc. This is especially useful when multiple liquids need to be filled alternately, such as the alternating filling of paraffin and electrolyte in a three-way valve. While the rotary table allows for a centralized layout of multiple stations, it also occupies a large area, resulting in an excessively large overall size for this type of filling machine, preventing miniaturization.

[0020] This disclosure relates to a three-way valve filling device. In one embodiment, the three-way valve filling device includes a valve body loading / unloading assembly and a valve body filling assembly; the valve body loading / unloading assembly includes a valve body conveyor belt, a valve body loading component, and a valve body unloading component, the valve body conveyor belt being used to transport the three-way valve, the valve body loading component being used to load unfilled three-way valves to a placement position, and the valve body unloading component being used to unload filled three-way valves from the placement position; the valve body filling assembly includes an annular filling chain conveyor belt, a filling component, and multiple filling clamps, the annular filling chain conveyor belt having multiple placement... Each of the aforementioned filling fixtures is positioned at a designated placement location, and the filling fixture is used to hold the three-way valve. The filling component includes a filling support, a first filling device, and a second filling device. The filling support is located within the annular structure of the annular filling chain conveyor belt. Both the first and second filling devices are movably mounted on the filling support, with the first and second filling devices spaced apart. The first filling device is used to fill the three-way valve with a first filling liquid, and the second filling device is used to fill the three-way valve with a second filling liquid. The valve body loading component transfers the three-way valve to the annular filling chain conveyor belt. The filling fixture on the annular filling chain conveyor belt fixes the three-way valve, while the three-way valve moves along the annular conveying route of the annular filling chain conveyor belt. The first and second filling devices are located on the filling support within the annular structure of the annular filling chain conveyor belt to fill the three-way valve separately, thereby reducing the overall area occupied by the filling area and effectively reducing the overall size of the three-way valve filling device.

[0021] Please see Figure 1 This is a schematic diagram of the structure of a three-way valve filling device according to an embodiment of the present disclosure.

[0022] One embodiment of the three-way valve filling device 10 includes a valve body loading / unloading assembly 100 and a valve body filling assembly 200. Please refer to both. Figure 2 The valve body loading / unloading assembly 100 includes a valve body conveyor belt 110, a valve body loading component 120, and a valve body unloading component 130. The valve body conveyor belt 110 is used to transport three-way valves, the valve body loading component 120 is used to load unfilled three-way valves to the placement position, and the valve body unloading component 130 is used to unload filled three-way valves from the placement position. Please refer to the following: Figure 3The valve body filling assembly 200 includes an annular filling chain conveyor belt 210, a filling component 220, and multiple filling clamps 230. The annular filling chain conveyor belt 210 has multiple placement positions, and each filling clamp 230 is disposed at one of the placement positions. The filling clamp 230 is used to place the three-way valve. The filling component 220 includes a filling support 222, a first filling device 224, and a second filling device 226. The filling support 222 is located within the annular structure of the annular filling chain conveyor belt 210. The first filling device 224 and the second filling device 226 are both movably disposed on the filling support 222. The first filling device 224 and the second filling device 226 are spaced apart. The first filling device 224 is used to fill the three-way valve with a first filling liquid, and the second filling device 226 is used to fill the three-way valve with a second filling liquid.

[0023] In this embodiment, the valve body loading component 120 transfers the three-way valve to the annular filling chain conveyor belt 210. The filling clamp 230 on the annular filling chain conveyor belt 210 fixes the three-way valve. At the same time, the three-way valve moves along the annular conveying route of the annular filling chain conveyor belt 210. The first filling device 224 and the second filling device 226 are located on the filling bracket 222 within the annular structure of the annular filling chain conveyor belt 210 to fill the three-way valve respectively, thereby reducing the area occupied by the overall filling area and effectively reducing the overall size of the three-way valve filling device.

[0024] In one embodiment, please refer to Figure 4 The filling fixture 230 has a placement hole 202, which communicates with the interior of the filling fixture 230 and is used to insert a three-way valve. In this embodiment, the filling fixture 230 corresponds one-to-one with the placement position on the annular filling chain conveyor belt 210. The filling fixture 230 serves as a fixing component for the three-way valve, and its interior is used to accommodate the three-way valve, allowing it to be secured within the fixture. The placement hole 202 is located at the top of the filling fixture 230 and serves as its mounting port. After the valve body material component 120 grasps the three-way valve, it inserts the valve into the filling fixture 230 through the placement hole 202, facilitating quick placement of the three-way valve onto the filling fixture 230.

[0025] Furthermore, the diameter of the placement hole 202 gradually increases in the direction away from the annular filling chain conveyor belt 210. In this embodiment, the placement hole 202 serves as the mounting hole for a three-way valve on the filling fixture 230. The diameter of the placement hole 202 gradually increases from bottom to top, causing the hole wall of the placement hole 202 to be inclined downwards, facilitating the rapid introduction of the three-way valve into the filling fixture 230. Moreover, when the three-way valve is installed in the filling fixture 230, the button of the three-way valve slides against the inclined hole wall of the placement hole 202, facilitating the pressing of the button of the three-way valve and opening up the three isolated spaces inside the three-way valve, thereby facilitating the filling of the three-way valve.

[0026] In another embodiment, please refer to Figure 4 The filling fixture 230 also has an observation hole 204, which communicates with the interior of the filling fixture 230. The observation hole 204 is used to observe the position of the three-way valve within the filling fixture 230. In this embodiment, the observation hole 204 is located on the side of the filling fixture 230 and maintains communication with the interior of the filling fixture 230, making the filling fixture 230 a hollow structure. The observation hole 204 allows observation of the three-way valve's insertion into the filling fixture 230, facilitating the determination of the valve's alignment.

[0027] Furthermore, please refer to Figure 1 The valve body loading / unloading assembly 100 further includes a loading alignment sensor 140, which is disposed on the valve body conveyor belt 110 and corresponds to the valve body loading component 120. The sensing end of the loading alignment sensor 140 faces the observation hole 204. In this embodiment, the loading alignment sensor 140 faces the observation hole 204, and the sensing end of the loading alignment sensor 140 is aligned with the interior of the filling fixture 230, which facilitates sensing whether the three-way valve in the filling fixture 230 is accurately installed, thereby facilitating the determination of the installation position of the three-way valve in the filling fixture 230.

[0028] In one embodiment, please refer to Figure 4The valve body filling assembly 200 further includes a valve body placement guide 240, which is movably connected to the filling bracket 222. The valve body placement guide 240 has a guide hole 206, which is aligned with the placement hole 202. The guide hole 206 is located on the side of the filling fixture 230 opposite to the annular filling chain conveyor belt 210. In this embodiment, the guide hole 206 is located above the filling fixture 230, and the guide hole 206 and the placement hole 202 are on the same straight line, that is, the center of the guide hole 206 and the center of the placement hole 202 are on the same axis. The guide hole 206 serves as a front mounting hole for the three-way valve to be installed into the filling fixture 230. The guide hole 206 adjusts the installation posture of the three-way valve to be consistent with the placement hole 202, so that the three-way valve remains aligned with the placement hole 202 before being installed into the filling fixture 230, making it easy to quickly install the three-way valve into the filling fixture 230.

[0029] Further, please refer to Figure 4 The valve body placement guide 240 includes a guide bracket 242, a transverse drive cylinder 244, a longitudinal slide rail 246, and a guide slider 248. The guide bracket 242 is slidably connected to the filling bracket 222. The transverse drive cylinder 244 is disposed on the filling bracket 222, and its drive end is connected to the guide bracket 242 to drive the guide bracket 242 away from or towards the filling fixture 230. The longitudinal slide rail 246 is disposed on the guide bracket 242, and the guide slider 248 is slidably disposed on the longitudinal slide rail 246. The guide hole 206 is located on the guide slider 248. In this embodiment, the guide bracket 242 is disposed opposite to the valve body loading component 120. The transverse drive cylinder 244 is used to push the guide bracket 242 laterally, which facilitates adjustment of the lateral positional deviation between the guide hole 206 and the placement hole 202. The longitudinal slide rail 246 serves as the longitudinal adjustment guide rail for the guide slider 248, enabling the guide slider 248 to be raised and lowered. This facilitates the adjustment of the longitudinal positional deviation between the guide hole 206 and the placement hole 202, thereby improving the alignment accuracy between the guide hole 206 and the placement hole 202.

[0030] In another embodiment, the guide slider moves along the longitudinal slide rail via a lifting motor, i.e., the lifting motor is mounted on the guide bracket, and the lifting shaft of the lifting motor is connected to the guide slider.

[0031] In another embodiment, the guide slider is moved by a linear motor on a longitudinal slide rail, i.e., the linear motor is mounted on the longitudinal slide rail and the guide slider is connected to the linear motor.

[0032] In another embodiment, the diameter of the guide hole 206 gradually increases in the direction away from the annular filling chain conveyor belt 210. The guide hole 206 is similar to the placement hole 202 and also has an inclined inner wall structure for quickly introducing the three-way valve.

[0033] In one embodiment, please refer to the following: Figure 3 and Figure 5 The valve body filling assembly 200 further includes a valve body flattening component 250, which includes a valve body flattening bracket 252, a valve body flattening motor 254, and a pressing plate 256. The valve body flattening bracket 252 is located between the valve body conveyor belt 110 and the annular filling chain conveyor belt 210. The valve body flattening motor 254 is connected to the valve body flattening bracket 252, and the pressing plate 256 is connected to the flattening lifting shaft of the valve body flattening motor 254. The pressing plate 256 is used to press against the top of the three-way valve. In this embodiment, the valve body flattening bracket 252 is disposed between the valve body feeding component 120 and the filling component 220, that is, the valve body flattening bracket 252 is located between the feeding station and the filling station of the annular filling chain conveyor belt 210. The valve body flattening motor 254 is fixed on the valve body flattening bracket 252. The flattening lifting shaft of the valve body flattening motor 254 is fixedly connected to the flattening plate 256. The flattening plate 256 presses the uninstalled part of the three-way valve into place by pressing against the top of the three-way valve, so that the end of the three-way valve is kept flush. This ensures that the installation posture of the three-way valve on the filling fixture 230 is consistent, which facilitates the subsequent standardized liquid filling operation.

[0034] In one embodiment, please refer to Figure 6 The valve body filling assembly 200 further includes a valve body ejector 260, which includes a valve body ejector cylinder 262 and an ejector rod 264. The valve body ejector cylinder 262 corresponds to the valve body unloading component 130. Please refer to [link / reference]. Figure 7The filling fixture 230 has an ejection hole 208, which communicates with the interior of the filling fixture 230. An ejection rod 264 is connected to the telescopic shaft of the ejection cylinder. The ejection rod 264 passes through the ejection hole 208 to lift the three-way valve inside the filling fixture 230. In this embodiment, the valve body ejector 260 is located at the filling and unloading station of the annular filling chain conveyor belt 210. Specifically, the valve body ejector 260 is positioned opposite to the valve body unloading component 130. The valve body ejection cylinder 262 serves as the power output source for the ejection rod 264. The telescopic shaft of the valve body ejection cylinder 262 is fixedly connected to the ejection rod 264. The telescopic shaft of the valve body ejection cylinder 262 moves the ejection rod 264 by telescopic movement, so that the ejection rod 264 faces or moves away from the filling fixture 230. This facilitates the ejection rod 264 passing through the ejection hole 208 and abutting against the three-way valve inside the filling fixture 230. This allows the ejection rod 264 to eject the three-way valve out of the filling fixture 230, realizing the ejection operation of the three-way valve, and facilitating the removal of the three-way valve by the valve body unloading component 130.

[0035] In another embodiment, there are three first filling devices 224 and two second filling devices 226. The three first filling devices 224 and the two second filling devices 226 are arranged alternately, that is, there is one second filling device 226 between two adjacent first filling devices 224. The first filling devices 224 are used to fill silicone oil and the second filling devices 226 are used to fill electrolyte.

[0036] In another embodiment, the valve body loading component 120 and the valve body unloading component 130 are mechanical claw structures to facilitate the gripping and transfer of the three-way valve.

[0037] The three-way valve body contains silicone oil and electrolyte. To facilitate the separate recycling of electrolyte and silicone oil, a membrane with extremely fine pores is usually installed on the three-way valve body. During recycling, the electrolyte permeates through the membrane, while the silicone oil remains inside the valve body, achieving separate collection. However, due to the small pore size and area of ​​the membrane, the traditional method of applying the membrane is still manual. This results in poor consistency when applying the membrane manually, requiring rework and re-application, leading to significant consumption of the membrane.

[0038] To reduce screen protector consumption, please refer to [link / reference]. Figure 8The three-way valve filling device 10 further includes a film-applying indexing plate 300, a valve body sealing cap feeding assembly 400, a film-applying feeding assembly 500, a sealing assembly 600, and a cap feeding assembly 700. The film-applying indexing plate 300 has multiple cap mounting stations, which are sequentially spaced along the edge of the film-applying indexing plate 300. The valve body sealing cap feeding assembly 400 includes a cap linear vibration feeding component 410 and a cap transfer component 420. The cap linear vibration feeding component 410 is used for linear vibration conveying of bottle caps. The cap transfer component 420 is located between the cap linear vibration feeding component 410 and the film-applying indexing plate 300. The cap transfer component 420 is used to transfer the bottle caps on the cap linear vibration feeding component 410 to the cap mounting stations, with the cap opening facing away from the film-applying indexing plate 300. The film-applying feeding assembly 500 includes a heat-sealing film cutter 510 and a heat-sealing film transfer assembly 520. The heat-sealing film cutter 510 is used to cut out the heat-sealing film. The heat-sealing film transfer assembly 520 is located between the heat-sealing film cutter 510 and the film-applying indexing plate 300. The heat-sealing film transfer assembly 520 is used to transfer the heat-sealing film on the heat-sealing film cutter 510 to the bottle cap at the cap installation station. The sealing assembly 600 is used to heat-seal the heat-sealing film inside the bottle cap at the cap installation station. The unloading and capping assembly 700 is used to install the heat-sealed bottle cap onto the valve port of a three-way valve.

[0039] In this embodiment, the bottle cap and heat-sealing film are fed separately. The heat-sealing film transfer component 520 loads the heat-sealing film into the bottle cap separately, which makes it easier for the heat-sealing film to align with the bottle cap. This ensures that the heat-sealing film and the heat-sealing position inside the bottle cap are aligned, thereby improving the alignment degree between the heat-sealing film and the bottle cap. This improves the consistency of the heat-sealing film application, avoids rework, and effectively reduces the amount of film consumed.

[0040] In one embodiment, please refer to Figure 8The three-way valve filling device 10 further includes a cap static eliminator assembly 800a. The cap static eliminator assembly 800a includes a first static frame 810 and a first static eliminator 820. The first static frame 810 is located between the cap linear vibrating feeder 410 and the heat-sealing film cutter 510. The first static eliminator 820 is mounted on the first static frame 810, with its discharge end facing the bottle cap. In this embodiment, the first static frame 810 serves as the mounting frame for the first static eliminator 820. The first static eliminator 820 is mounted on the first static frame 810 and eliminates static electricity from the bottle caps on the film-applying indexing plate 300, reducing the amount of static electricity inside the bottle caps and preventing static electricity from remaining inside the bottle caps, thus preventing the subsequent heat-sealing film from flying off due to static electricity inside the bottle caps. The first static eliminator 820 is located after the bottle cap feeding station and before the heat sealing film feeding station.

[0041] Further, please refer to Figure 8 The three-way valve filling device 10 further includes a cap film static elimination assembly 800b, which includes a second static frame 830 and a second static eliminator 840. The second static frame 830 is located between the heat-sealing film cutter 510 and the sealing film assembly 600. The second static eliminator 840 is mounted on the second static frame 830, and the discharge end of the second static eliminator 840 faces the heat-sealing film inside the bottle cap. In this embodiment, the second static eliminator 830 serves as the mounting bracket for the second static eliminator 840. The second static eliminator 840 is mounted on the second static eliminator 830. The second static eliminator 840 simultaneously eliminates static electricity from the bottle caps and heat-sealing film on the film-applying indexing plate 300, reducing the amount of static electricity on the bottle caps and heat-sealing film on the film-applying indexing plate 300. This prevents static electricity from existing on the bottle caps and heat-sealing film, thus avoiding the situation where the heat-sealing film flies off inside the bottle cap due to static electricity when the film-applying indexing plate 300 rotates. The second static eliminator 840 is located after the heat-sealing film loading station and before the heat-sealing station.

[0042] In one embodiment, please refer to Figure 8The three-way valve filling device 10 also includes multiple cap mounting seats 900, each cap mounting seat 900 being located at a cap mounting station. Each cap mounting seat 900 has a mounting groove 902 for placing bottle caps. In this embodiment, the cap mounting seat 900 is located on the film-applying indexing plate 300, and each cap mounting seat 900 corresponds one-to-one with a cap mounting station. Bottle caps are held in the mounting grooves 902. Specifically, each cap mounting seat 900 has at least two mounting grooves 902, allowing the film-applying indexing plate 300 to have multiple bottle cap placement clamps, facilitating batch fixing and sealing of bottle caps to improve sealing efficiency.

[0043] In one embodiment, please refer to Figure 9 The lid transfer component 420 includes a lid transfer frame 422, a first lid transfer horizontal guide rail 424, a second lid transfer horizontal guide rail 426, a lid transfer vertical guide rail 428, a lid transfer slider 421, and a lid transfer mechanical clamp 423. The lid transfer frame 422 is located between the lid linear vibration feeding component 410 and the film-applying indexing plate 300. The first lid transfer horizontal guide rail 424 and the second lid transfer horizontal guide rail 426 are both mounted on the lid transfer frame 422. The cap transfer vertical guide rail 428 is slidably disposed on the first cap transfer horizontal guide rail 424, the cap transfer mechanical clamp 423 is slidably disposed on the cap transfer vertical guide rail 428, and the cap transfer slider 421 is slidably disposed on the second cap transfer horizontal guide rail 426. The cap transfer slider 421 is used to carry the bottle caps conveyed by the cap linear vibrating loading component 410, and the cap transfer mechanical clamp 423 is used to transfer the bottle caps on the cap transfer slider 421 to the cap installation station. In this embodiment, the cap transfer frame 422 serves as the mounting frame for the cap transfer mechanical clamp 423. The first cap transfer horizontal guide rail 424 is mounted on the cap transfer frame 422, and the cap transfer vertical guide rail 428 moves along the horizontal direction of the first cap transfer horizontal guide rail 424. The cap transfer mechanical clamp 423 is slidably connected to the cap transfer vertical guide rail 428, allowing the cap transfer mechanical clamp 423 to move in two mutually perpendicular directions. This facilitates the cap transfer mechanical clamp 423 accurately gripping the bottle cap onto the cap mounting position of the film-applying indexing plate 300.

[0044] The cap transfer slider 421 is slidably connected to the second cap transfer horizontal guide rail 426, allowing the cap transfer slider 421 to move along the second cap transfer horizontal guide rail 426 in another horizontal direction. The cap transfer slider 421 serves as a transfer seat for the bottle cap. It moves via the second cap transfer horizontal guide rail 426 to the feeding port of the cap linear vibrating feeder 410 to receive the bottle cap. The bottle cap is then aligned with the cap mounting position on the film-applying indexing plate 300. Finally, the cap transfer mechanical clamp 423 quickly grips the bottle cap onto the cap mounting position. The first cap transfer horizontal guide rail 424 is parallel to the radial direction of the film-applying indexing plate 300, the second cap transfer horizontal guide rail 426 is parallel to the tangential direction of the film-applying indexing plate 300, and the cap transfer vertical guide rail 428 is perpendicular to the film-applying indexing plate 300.

[0045] In one embodiment, please refer to the following: Figure 10 and Figure 11 The heat-sealing film cutting component 510 includes a cutting cylinder 512, a cutting bracket 514, a heat-sealing film conveying seat 516, and at least two heat-sealing film slicing columns 518. The cutting cylinder 512 is fixedly connected to the cutting bracket 514. The heat-sealing film conveying seat 516 is located on the side of the cutting bracket 514 away from the cutting cylinder 512. The heat-sealing film conveying seat 516 has a first through hole 502 and a second through hole 504 that are interconnected. The first through hole 502 is used to transport the film strip. The heat-sealing film slicing column 518 is fixedly connected to the lifting end of the cutting cylinder 512. The heat-sealing film slicing column 518 passes through the second through hole 504 to cut the film strip into heat-sealing film. In this embodiment, the cutting cylinder 512 and the heat-sealing film conveying seat 516 are located on both sides of the cutting bracket 514, and are arranged opposite to each other. The heat-sealing film conveying seat 516 is hollow inside, and the first through hole 502 serves as a transmission cavity for the film strip. The heat-sealing film slicing column 518 is fixed on the lifting end of the cutting cylinder 512. Driven by the cutting cylinder 512, the heat-sealing film slicing column 518 cuts the film strip through the second through hole 504 and pushes out the cut heat-sealing film, making it easy for the heat-sealing film transfer member 520 to remove the heat-sealing film. After the heat-sealing film is removed, the cutting cylinder 512 drives the heat-sealing film slicing column 518 to descend, so that the heat-sealing film slicing column 518 comes into contact with the film strip, facilitating the continued transmission of the film strip, thereby cutting the subsequent position of the film strip.

[0046] Further, please refer to Figure 11The heat-sealing film cutting component 510 further includes a slicing guide rod 511 and a slicing shock-absorbing spring 513. The slicing guide rod 511 is fixedly connected to the lifting end of the cutting cylinder 512, and the slicing shock-absorbing spring 513 is sleeved on the slicing guide rod 511 and abuts against the lifting end of the cutting cylinder 512. The heat-sealing film conveying base 516 includes a conveying base 5162 and a film pressing plate 5164. The conveying base 5162 is connected to the cutting cylinder 512. The support 514 is fixedly connected. The transmission base 5162 has a third through hole 506 communicating with the first through hole 502. The diaphragm pressing plate 5164 is received within the first through hole 502. The diaphragm pressing plate 5164 has a fourth through hole 508. The slice guide rod 511 passes through the third through hole 506 and is movably inserted into the fourth through hole 508. The slice damping spring 513 passes through the third through hole 506 and abuts against the diaphragm pressing plate 5164. In this embodiment, the transmission base 5162 has the first through hole 502 and the second through hole 504, and the third through hole 506 is also located on the transmission base 5162. The slicing guide rod 511 is sleeved with the slicing damping spring 513, that is, the slicing damping spring 513 is sleeved on the outside of the slicing guide rod 511. Both the slicing guide rod 511 and the slicing damping spring 513 pass through the third through hole 506. The end of the slicing guide rod 511 is also located in the fourth through hole 508, which provides space for the slicing guide rod 511 to move up and down. The slicing damping spring 513 also contacts the diaphragm pressing plate 5164, so that when the heat-sealing film slicing column 518 cuts the film strip, the slicing guide rod 511 and the slicing damping spring 513 push up the diaphragm pressing plate 5164, thereby making the diaphragm pressing plate 5164 hold the film strip against the inner wall of the first through hole 502, so as to avoid the film strip from shifting during cutting and to facilitate the cutting of heat-sealing film that meets the requirements. The slice damping spring 513 provides a damping force to the diaphragm pressure plate 5164 to prevent the diaphragm from being broken by the pressure between the diaphragm pressure plates 5164.

[0047] In another embodiment, please refer to Figure 10The heat-sealing film transfer component 520 includes a heat-sealing film transfer frame 522, a heat-sealing film transfer guide rail 524, a heat-sealing film vertical transfer cylinder 526, a film-taking variable-distance cylinder 528, and at least two film-taking needles 521. The heat-sealing film transfer frame 522 is disposed adjacent to the cutting bracket 514. The heat-sealing film transfer guide rail 524 is disposed on the heat-sealing film transfer frame 522. The heat-sealing film vertical transfer cylinder 526 is slidably disposed on the heat-sealing film transfer guide rail 524. The lifting end of the heat-sealing film vertical transfer cylinder 526 is connected to the film-taking variable-distance cylinder 528. Each film-suction end of the film-taking variable-distance cylinder 528 is connected to one of the film-taking needles 521 to adjust the spacing between the film-taking needles 521. Each film-taking needle 521 is disposed opposite to a heat-sealing film slicing column 518 to pick up the heat-sealing film on the heat-sealing film slicing column 518. In this embodiment, the heat-sealing film transfer frame 522 serves as the mounting frame for the heat-sealing film transfer guide 524, the heat-sealing film vertical transfer cylinder 526, the film-taking variable-pitch cylinder 528, and at least two film-taking needles 521. The heat-sealing film vertical transfer cylinder 526 is slidably connected to the heat-sealing film transfer guide 524, so that the heat-sealing film vertical transfer cylinder 526 moves along the direction of the heat-sealing film transfer guide 524. Specifically, the heat-sealing film transfer guide 524 is parallel to the radial direction of the film-applying indexing plate 300. The film-taking variable-pitch cylinder 528 is fixedly connected to the lifting end of the vertical transfer cylinder 526 for heat-sealing film. The film-taking needle 521 is fixed on the suction end of the film-taking variable-pitch cylinder 528, facilitating the film-taking needle 521 to pick up the heat-sealing film cut from the heat-sealing film slicing column 518. Specifically, the film-taking needle picks up the heat-sealing film by negative pressure adsorption. The distance between adjacent film-taking needles 521 is adjusted by the suction end of the film-taking variable-pitch cylinder 528, that is, by adjusting the spacing between the suction ends of the film-taking variable-pitch cylinder 528, the spacing between the film-taking needles 521 is adjustable. When the spacing between the heat-sealing film slicing columns 518 is adjusted, the spacing of the film-taking needles 521 can be adjusted synchronously. Moreover, by adjusting the spacing between the heat-sealing film slicing columns 518 and the film-taking needles 521, the utilization rate of the film strip is improved, and the amount of film strip used is reduced.

[0048] In one embodiment, please refer to Figure 12The sealing assembly 600 includes a film transfer component 610 and a heat sealer 620. The film transfer component 610 includes a film transfer cylinder 612, a film transfer frame 614, and at least two cap film transfer mechanical clamps 616. The rotating shaft of the film transfer cylinder 612 is fixedly connected to the film transfer frame 614. The cap film transfer mechanical clamps 616 are disposed on the film transfer frame 614, and at least two cap film transfer mechanical clamps 616 are arranged opposite to each other. The cap film transfer mechanical clamps 616 are used to clamp bottle caps onto the heat sealing platform of the heat sealer 620. The heat sealer 620 is located on the side of the film transfer frame 614 opposite to the film-applying indexing plate 300. In this embodiment, the film transfer cylinder 612 serves as the power source for the film transfer frame 614, providing rotational power. The cap film transfer mechanical clamp 616 is fixed on the film transfer frame 614. The cap film transfer mechanical clamp 616 grabs the bottle cap on the film-applying indexing plate 300. The film transfer frame 614 rotates under the drive of the film transfer cylinder 612, which drives the cap film transfer mechanical clamp 616 to rotate, so as to transfer the bottle cap to the heat sealer 620, thereby facilitating the heat sealing operation of the bottle cap.

[0049] Further, please refer to Figure 12The film transfer component 610 further includes a gripper control cylinder 618, a gripper vertical movement cylinder 611, a film-fixing rotation rod 613, and a film-fixing rotation cylinder 615. The gripper vertical movement cylinder 611 and the film-fixing rotation cylinder 615 are both mounted on the film transfer frame 614. The lifting end of the gripper vertical movement cylinder 611 is connected to the gripper control cylinder 618, and the driving end of the gripper control cylinder 618 is connected to the cap film transfer mechanical clamp 616 to drive the cap film transfer mechanical clamp 616 to grip the bottle cap. The rotating shaft of the film-fixing rotation cylinder 615 is connected to one end of the film-fixing rotation rod 613, and the other end of the film-fixing rotation rod 613 is used to be embedded inside the bottle cap to confine the heat-sealing film inside the bottle cap. In this embodiment, the gripper control cylinder 618 serves as the driving component of the cap film transfer mechanical clamp 616, driving the cap film transfer mechanical clamp 616 to perform pick-and-place actions. The gripper vertical movement cylinder 611 provides lifting power to the gripper control cylinder 618, making the height difference between the cap film transfer mechanical clamp 616 and the film-applying indexing plate 300 adjustable, facilitating the accurate pick-and-place of bottle caps by the cap film transfer mechanical clamp 616. The film-fixing rotation cylinder 615 is fixed on the film transfer frame 614, and provides power for the swinging of the film-fixing rotation rod 613. The film-fixing rotation rod 613 rotates around the rotation axis of the film-fixing rotation cylinder 615, causing the film-fixing rotation rod 613 to swing on the film transfer frame 614. The end of the fixed film rotating rod 613 corresponds to the cap film transfer mechanical clamp 616. Specifically, when the cap film transfer mechanical clamp 616 grabs the bottle cap, the end of the fixed film rotating rod 613 extends into the bottle cap grabbed by the cap film transfer mechanical clamp 616, so that the heat sealing film inside the bottle cap is confined therein, avoiding the heat sealing film inside the bottle cap from flying away when the film transfer frame 614 rotates, thereby reducing the loss of heat sealing film.

[0050] In one embodiment, this disclosure also provides a three-way valve filling machine, including the three-way valve filling device described in any of the above embodiments. In this embodiment, the three-way valve filling device includes a valve body loading / unloading assembly and a valve body filling assembly; the valve body loading / unloading assembly includes a valve body conveyor belt, a valve body loading component, and a valve body unloading component. The valve body conveyor belt is used to transport the three-way valve, the valve body loading component is used to load unfilled three-way valves to a placement position, and the valve body unloading component is used to unload filled three-way valves from the placement position; the valve body filling assembly includes an annular filling chain conveyor belt, a filling component, and multiple filling clamps, the annular filling chain conveyor belt having multiple placement positions. Each filling fixture is positioned at a designated location and is used to hold a three-way valve. The filling component includes a filling support, a first filling device, and a second filling device. The filling support is located within the annular structure of the annular filling chain conveyor belt. Both the first and second filling devices are movably mounted on the filling support, spaced apart. The first filling device is used to fill the three-way valve with a first filling liquid, and the second filling device is used to fill the three-way valve with a second filling liquid. The valve body loading component transfers the three-way valve onto the annular filling chain conveyor belt. The filling fixture on the annular filling chain conveyor belt fixes the three-way valve, while the three-way valve moves along the annular conveying path of the annular filling chain conveyor belt. The first and second filling devices are located on the filling support within the annular structure of the annular filling chain conveyor belt to fill the three-way valve separately, thereby reducing the overall area occupied by the filling area and effectively reducing the overall size of the three-way valve filling device.
