Description

Technical Field

[0001] This invention belongs to the field of intelligent positioning and feeding technology, specifically relating to an intelligent positioning and feeding splicing device and method for an integrated log and board machine head. Background Technology

[0002] An integrated intelligent positioning, feeding, and splicing device for log panels is a set of intelligent front-end equipment specifically designed for solid wood processing. Its core lies in integrating the two major processes of "log panel feeding" and "seamless splicing" into an automated production line. Using high-precision vision or laser sensors, it intelligently identifies and scans the outline, size, and defects of each raw board, feeding the data back to the integrated machine head in real time. This machine head can automatically calculate and adjust the gripping angle and splicing pressure based on the unique natural shape of each board, like a "puzzle," precisely aligning, pushing, and gluing irregular log panels together into a predetermined, regular board surface on the conveyor belt.

[0003] However, traditional devices still have the following problems when in use: Patent application publication number CN220240349U discloses a self-positioning feeding device for sheet metal. This device lifts the positioning plate using a lifting unit and then moves the positioning plate using a transverse unit, thereby pushing the sheet metal on the conveying unit to the positioning component for transverse positioning, thus solving the technical problem of sheet metal not being able to be positioned during continuous sheet metal conveying.

[0004] In the existing technology, the positioning of logs relies on the feeding mechanism sliding along the track to adjust the position. The feeding mechanism does not have a rotation function and cannot achieve angle adjustment. Therefore, we need an intelligent positioning, feeding, and splicing device and method for an integrated log board machine head to solve the problem that the feeding mechanism does not have a rotation function, and to enable the feeding mechanism to rotate.

[0012] Preferably, an electric push rod is fixedly connected to the outer wall of the bottom of the second mounting plate, and a limiting mechanism is fixedly connected to the output end of the electric push rod.

[0015] A method for intelligent positioning, feeding, and splicing of log panels using an integrated machine head is based on an integrated machine head intelligent positioning, feeding, and splicing device. This method includes the following steps: S1: Adsorption and Pickup: Simultaneously start the cylinder and vacuum pump to drive the rotating frame to lower the buffer rod and suction cup. The buffer rod transforms the rigid impact into flexible contact, so that the suction cup adheres to the surface of the wood board with increasing pressure and establishes negative pressure adsorption. S2: Lifting and Transfer: The cylinder drives the rotating frame and suction cup to rise synchronously, completing the vertical lifting of the logs. Combined with the horizontal sliding of the sliding plate on the track frame, the logs are transferred from the picking position to the preset splicing station. S3: Edge detection: The edge of the log board is scanned and detected by the sensor installed on the telescopic positioning rod to obtain the outline or position information of the board and feed it back to the control system; S4: Angle adjustment: The starting motor drives the rotating frame through the transmission chain of the main shaft, mounting sleeve, limit block, slide rod, gear and teeth to rotate the adsorbed board in the horizontal plane to the preset splicing angle. After completion, the electric push rod drives the limit mechanism to insert the fixed wheel and mechanically lock the rotating frame. S5: Automatic lubrication: As the slide bar descends with the rotating frame, the solution chamber moves down synchronously. The sealing plate opens the discharge port due to magnetic force, and the lubricant flows to the outer wall of the slide bar through the through hole and the guide groove, reducing the friction between the slide bar and the mounting sleeve. After the slide bar rises, the reset spring drives the sealing plate back to its original position to block the discharge port and stop the liquid supply.

[0016] Compared with the prior art, the beneficial effects of the present invention are: By adding rotational degrees of freedom, the adsorbed logs can actively rotate to a preset splicing angle in the horizontal plane, thereby completing the independent correction of the log posture without moving the entire machine's feeding track. This improves the flexibility of splicing alignment and reduces the dependence on track positioning accuracy. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1, please refer to Figures 1 to 12 This invention provides a technical solution for an integrated intelligent positioning and feeding splicing device for log boards: it includes a track frame 1, a sliding plate 2 slidably connected to the outer wall of the top of the track frame 1, a cylinder 3 fixedly connected to the outer wall of the top of the sliding plate 2, a vacuum pump 5 fixedly connected to the outer wall of the top of the sliding plate 2, a motor 4 fixedly connected to the outer wall of the top of the sliding plate 2, a rotating frame 41 rotatably connected below the output end of the cylinder 3, a telescopic positioning rod 31 fixedly connected to the outer wall of the bottom of the sliding plate 2, a groove 34 opened on the outer wall of the top of the rotating frame 41, an installation plate 32 fixedly connected to the outer wall of the telescopic positioning rod 31, and a sensor 33 embedded and fixedly connected to the bottom of the installation plate 32.

[0032] This structure is used to eliminate impact loads caused by rapid feeding or morphological errors of logs, avoiding damage such as indentations, chipping, and microcracks. Compared with existing rigid contact, this invention achieves a gradient increase in contact pressure through a buffer element. While ensuring positioning accuracy, it provides structural protection for the integrity of the log surface, ultimately creating the optimal contact state for suction cup 52 adsorption. This ensures that the lip of suction cup 52 deforms uniformly under the buffering effect to form an effective negative pressure seal, without damaging the wood fibers due to excessive compression.

[0033] In Example 2, based on Example 1, a fixed sleeve 55 is fixedly connected to the outer wall of the top of the rotating frame 41. A fixed tube 58 is rotatably connected inside the fixed sleeve 55. The outer wall of the top of the fixed tube 58 is fixedly connected to the output end of the cylinder 3. A telescopic tube 53 is fixedly connected to the output end of the vacuum pump 5. A connecting tube 54 is fixedly connected to the outer wall of one end of the telescopic tube 53. An automatic solenoid valve 56 is fixedly connected inside the connecting tube 54. The outer wall of one end of the connecting tube 54 is fixedly connected through the outer wall of the fixed tube 58. A fixed shell 51 is fixedly connected to the outer wall of the bottom of the rotating frame 41. An air chamber 57 is opened inside the fixed shell 51. The outer wall of the top of the air chamber 57 is connected through the outer wall of the bottom of the fixed tube 58. A suction cup 52 is fixedly connected through the outer wall of the bottom of the fixed shell 51. A buffer rod 8 is fixedly connected to the outer wall of the bottom of the fixed shell 51.

[0034] This structure allows the rotating frame 41 to rotate independently of the fixed tube 58 while moving synchronously with it. This provides the angle adjustment freedom for the adsorbed log while maintaining the continuous sealing of the negative pressure air path. Compared with the existing fixed suction cup 52 structure, this invention solves the interference problem between air path connection and rotational action in motion by combining rotational connection and sealing structure, laying a stable structural and air path foundation for subsequent log posture adjustment.

[0035] In Example 3, based on Example 2, a main shaft 48 is fixedly connected to the output end of the motor 4. A mounting sleeve 43 is fixedly connected to the outer wall of the bottom of the main shaft 48. A slide rod 44 is slidably connected inside the mounting sleeve 43. A gear 45 is fixedly connected to the outer wall of the bottom of the slide rod 44. A groove is provided on the outer wall of the rotating frame 41. A tooth 46 is fixedly connected to the outer wall of the groove. The outer wall of the tooth 46 meshes with the outer wall of the gear 45. The inside of the groove is in movable contact with the outer walls of the upper and lower sides of the gear 45. A limit block 47 is fixedly connected to the outer wall of the slide rod 44. The outer wall of the limit block 47 is slidably connected to the outer wall of the mounting sleeve 43.

[0036] This invention adds a degree of rotational freedom, allowing the adsorbed logs to actively rotate to a preset splicing angle in the horizontal plane. This enables independent correction of the log posture without moving the entire machine's loading track, improving splicing alignment flexibility and reducing dependence on track positioning accuracy.

[0037] In Example 4, based on Example 3, a fixing rod 61 is fixedly connected to the outer wall of the bottom of the sliding plate 2, and a mounting plate 42 is fixedly connected to the outer wall of the bottom of the fixing rod 61. The interior of the mounting plate 42 is connected through to the outer wall of the mounting sleeve 43. A fixing wheel 6 is fixedly connected to the outer wall of the mounting sleeve 43. An electric push rod 64 is fixedly connected to the outer wall of the bottom of the mounting plate 42. A limiting mechanism 62 is fixedly connected to the output end of the electric push rod 64. The outer wall of one side of the limiting mechanism 62 is movably inserted into the outer wall of the fixing wheel 6. A limiting rod 63 is fixedly connected to the outer wall of the bottom of the mounting plate 42. The outer wall of the limiting rod 63 is slidably connected through to the inner wall of the limiting mechanism 62.

[0038] Through the interlocking reaction between the machines, the rotating frame 41 can be fixed. This interlocking locking structure intervenes after the angle adjustment is completed, and applies mechanical braking to the end of the transmission chain. This eliminates the angle deviation caused by external force disturbance or transmission gap after the adjustment is completed, so that the logs adsorbed on the rotating frame 41 are kept in the adjusted state. Compared with relying on the self-locking of the drive motor 4, the rigid constraint provided by the independent mechanical locking mechanism improves the reliability and long-term stability of angle maintenance, and provides a stable foundation for subsequent splicing processes.

[0039] In Example 5, based on Example 4, a magnetic plate 2 74 is fixedly connected to the inner wall of the fixed wheel 6, a solution chamber 7 is fixedly connected to the outer wall of the top of the slide rod 44, a shelf is fixedly connected to the inner wall of the solution chamber 7, a discharge port 71 is provided on the shelf, a sealing plate 72 is in close contact with the outer wall of the bottom of the discharge port 71, a magnetic plate 1 is fixedly connected to the outer wall of one end of the sealing plate 72, the outer wall of one side of the magnetic plate 1 and the outer wall of one side of the magnetic plate 2 74 are attracted by opposite poles, a return spring 73 is fixedly connected to the outer wall of one side of the sealing plate 72, the outer wall of one end of the return spring 73 is fixedly connected to the inner wall of one side of the shelf, a guide groove 441 is provided on the outer wall of the slide rod 44, and a through hole 442 is provided on the outer wall of the bottom of the solution chamber 7 located in the guide groove 441.

[0040] This structure utilizes the lifting and lowering motion of the slide bar 44 as the trigger condition, eliminating the need for an additional active control valve or external fluid supply device. This achieves lubrication of the sliding contact surface, reduces frictional resistance and wear, and extends the service life of moving parts. At the same time, the sealing plate 72 prevents continuous leakage of lubricating fluid, ensuring the intermittent nature of lubrication supply and reducing lubricating fluid waste and contamination of other parts of the equipment.

[0041] Example 6: A method for intelligent positioning, feeding, and splicing of an integrated log and board machine head, based on any one of the integrated machine head intelligent positioning, feeding, and splicing devices in Examples 1-5. This method for intelligent positioning, feeding, and splicing of an integrated log and board machine head includes the following steps: S1: Adsorption and pickup: Simultaneously start cylinder 3 and vacuum pump 5 to drive rotating frame 41 to lower buffer rod 8 and suction cup 52. The buffer rod 8 transforms rigid impact into flexible contact, so that suction cup 52 adheres to the surface of the wood board with increasing pressure and establishes negative pressure adsorption. By using the buffer rod 8, the rigid impact of the cylinder 3 is converted into flexible displacement, achieving a gradual fit between the suction cup 52 and the board, effectively eliminating impact loads and preventing physical damage such as indentations, chipping, or micro-cracks on the surface of the wood board. This ensures the adhesion strength while protecting the surface integrity of the precious wood.

[0042] S2: Lifting and Transfer: Cylinder 3 drives rotating frame 41 and suction cup 52 to rise synchronously, completing the vertical lifting of the log board. Combined with the horizontal sliding of sliding plate 2 on track frame 1, the log board is transferred from the picking position to the preset splicing station. It enables continuous automated operation of log boards from adsorption and pickup to fixed-point conveying, replacing manual handling and positioning, improving feeding efficiency and positional consistency, and providing accurate conveying and positioning for subsequent splicing processes.

[0043] S3: Edge detection: The edge of the log board is scanned and detected by the sensor 33 installed on the telescopic positioning rod 31 to obtain the outline or position information of the board and feed it back to the control system. It enables automatic edge recognition and position guidance before board splicing, replacing the traditional manual visual alignment method, so that the edges of the current log board are precisely aligned with the adjacent already loaded log boards, effectively improving the consistency of splicing gaps and the accuracy of the connection.

[0044] S4: Angle adjustment: The starting motor 4 drives the rotating frame 41 to rotate the adsorbed plate in the horizontal plane to the preset splicing angle through the transmission chain of the main shaft 48, mounting sleeve 43, limit block 47, slide rod 44, gear 45 and teeth 46. After completion, the electric push rod 64 drives the limit mechanism 62 to insert the fixed wheel 6 to mechanically lock the rotating frame 41. By adding rotational degrees of freedom, and after adjustment, a rigid constraint is provided by an independent mechanical locking mechanism to eliminate angular deviation caused by external force disturbances or transmission clearance, ensuring the reliability and long-term stability of the angle.

[0045] S5: Automatic lubrication: As the slide bar 44 descends with the rotating frame 41, the solution chamber 7 moves down synchronously. The sealing plate 72 opens the discharge port 71 due to magnetic force. The lubricating fluid flows to the outer wall of the slide bar 44 through the through hole 442 and the guide groove 441, reducing the friction between the slide bar 44 and the mounting sleeve 43. After the slide bar 44 rises, the return spring 73 drives the sealing plate 72 to return to its original position and block the discharge port 71, stopping the fluid supply. By using the lifting and lowering motion of the slide bar 44 as the trigger condition, no external control valve or liquid supply device is required, which reduces the frictional resistance and wear of the contact surface between the slide bar 44 and the mounting sleeve 43. At the same time, the intermittent liquid supply is achieved through the sealing action of the return spring 73, avoiding continuous leakage of lubricating fluid, which would cause waste and equipment contamination, and extending the service life of moving parts.

[0046] The working principle and usage process of this invention: During operation, firstly, the cylinder 3 and vacuum pump 5 are simultaneously activated. Then, the movement of cylinder 3 pushes the rotating frame 41 downwards. Due to the fixed connection between the rotating frame 41 and the fixed shell 51, and the fixed connection between the fixed shell 51 and the buffer rod 8, when cylinder 3 pushes the rotating frame 41 downwards, the fixed shell 51 causes the buffer rod 8 to move downwards as well. Simultaneously, the sliding plate 2 is connected to the rotating frame 41 via the telescopic positioning rod 31. When cylinder 3 moves, the telescopic positioning rod 31 is stretched or shortened accordingly. The telescopic positioning rod 31 increases the stability of the rotating frame 41's movement. The buffer rod 8 is located at the bottom of the fixed shell 51. The punch rod 8, by setting a buffer rod 8, converts the rigid drive of the cylinder 3 into a flexible displacement transmitted through springs and damping media to absorb the impact kinetic energy at the end of the descent, so that the suction cup 52 adheres to the surface of the log board with gradually increasing pressure. This structure is used to eliminate the impact load caused by rapid feeding or log board shape errors, and avoid damage such as indentation, chipping, and micro-cracks. Compared with existing rigid contact, the present invention achieves a gradient increase in contact pressure through a buffer element, which provides structural protection for the integrity of the log board surface while ensuring positioning accuracy. Ultimately, it creates the optimal contact state for the suction cup 52 to adhere, ensuring that the lip of the suction cup 52 deforms uniformly under the buffering effect to form an effective negative pressure seal, and preventing damage to the wood fibers due to excessive compression.

[0047] It should be noted that: by setting the telescopic tube 53, when the cylinder 3 pushes the rotating frame 41 to move downward or upward, the telescopic tube 53 can be stretched or shortened following the movement of the rotating frame 41.

[0048] This invention uses a vacuum pump 5 to create a negative pressure adsorption force between the suction cup 52 and the log, achieving firm positioning and gripping of the log. Subsequently, the cylinder 3 drives the rotating frame 41 and the suction cup 52 to rise synchronously, completing the vertical lifting action of the log. Combined with the horizontal sliding of the sliding plate 2 on the track frame 1, the log is transferred to the preset work position. This process realizes continuous automated operation of the log from adsorption and picking to fixed-point delivery, effectively replacing manual handling and positioning, and improving loading efficiency and position consistency. The sliding plate 2 and the track frame 1 adopt existing conventional structures, so their specific cooperation method will not be described in detail.

[0049] This invention achieves structural compatibility between airflow and relative rotation by fixing the sleeve 55 and rotating the frame 41, and rotating the tube 58 and the sleeve 55, with a sealing structure between them, while maintaining the tube 58 and the frame 41 in contact. This structure allows the frame 41 to rotate independently of the tube 58 while moving synchronously with it, thus providing angle adjustment freedom for the adsorbed wood board while maintaining continuous sealing of the negative pressure airflow. Compared to the existing fixed suction cup 52 structure, this invention solves the interference problem between airflow and rotation during movement by combining the rotating connection and the sealing structure, laying a stable structural and airflow foundation for subsequent adjustment of the wood board's posture.

[0050] This invention utilizes a mounting plate 32 mounted on a telescopic positioning rod 31, and a sensor 33 mounted on the mounting plate 32, to detect the edges of the log boards, acquire the outline or position information of the log boards, and feed the detection signal back to the control system. This drives the rotating frame 41 to adjust the position of the log boards, aligning the edges of the log boards with those of adjacent log boards that have already been loaded, thus completing the splicing. This structure achieves automatic edge detection and positioning guidance before the log boards are spliced, replacing the traditional manual visual alignment method, effectively improving the consistency of the splicing gaps, and providing an accurate positional reference for subsequent processes.

[0051] This invention utilizes a starting motor 4. Due to the fixed connection between the motor 4 and the main shaft 48, and the fixed connection between the main shaft 48 and the mounting sleeve 43, the motor 4's movement causes the main shaft 48 to drive the mounting sleeve 43 to rotate. Furthermore, due to the fixed connection between the limiting block 47 and the sliding rod 44, and the through-sliding connection between the limiting block 47 and the mounting sleeve 43, the sliding rod 44 rotates as the mounting sleeve 43 rotates, thanks to the limiting block 47. Finally, due to the fixed connection between the sliding rod 44 and the gear 45, and the meshing connection between the gear 45 and the teeth 46, the sliding rod 44 drives the gear 45... While rotating, gear 45 drives tooth 46 to rotate. Due to the fixed connection between tooth 46 and rotating frame 41, tooth 46 rotates under force, causing rotating frame 41 to rotate, which in turn causes rotating frame 41 to rotate, thereby rotating fixed shell 51. This allows the angle of the log board to be adjusted. By adding rotational freedom, this invention enables the adsorbed log board to actively rotate to a preset splicing angle in the horizontal plane. This allows for independent correction of the log board's posture without moving the entire machine's feeding track, improving splicing alignment flexibility and reducing dependence on track positioning accuracy.

[0052] It should be noted that, due to the sliding connection between the telescopic positioning rod 31 and the slide groove 34, the telescopic positioning rod 31 does not affect the rotation of the rotating frame 41. This invention utilizes the movable contact between the groove and the gear 45. When the cylinder 3 pushes the rotating frame 41 to move upward or downward, the groove causes the gear 45 to move accordingly. Through the movement of the gear 45, the slide rod 44 causes the limiting block 47 to slide upward or downward inside the mounting sleeve 43, thereby ensuring that the gear 45 is always engaged with the teeth 46. This structure ensures that the engagement between the gear 45 and the teeth 46 does not disengage due to the lifting and lowering of the rotating frame 41, thus guaranteeing the continuity of the power transmission path at different height positions.

[0053] It should be noted that before starting the motor 4, the electric push rod 64 should be started first. The movement of the electric push rod 64 releases the limit mechanism 62 from fixing the fixed wheel 6, allowing the mounting sleeve 43 to move freely.

[0054] After the angle of the log is adjusted, the electric push rod 64 is activated. Due to the fixed connection between the electric push rod 64 and the limiting mechanism 62, and the sliding connection between the limiting mechanism 62 and the limiting rod 63, when the electric push rod 64 drives the limiting mechanism 62 to move, the limiting mechanism 62 slides on the limiting rod 63 and simultaneously inserts into the fixed wheel 6, thereby limiting the fixed wheel 6. After limiting the fixed wheel 6, the mounting sleeve 43 can be fixed. Through the interlocking reaction between the machines, the rotating frame 41 can be fixed. This interlocking locking structure intervenes after the angle adjustment is completed, mechanically braking the end of the transmission chain, eliminating the angle deviation caused by external force disturbance or transmission gap after the adjustment, and keeping the log adsorbed on the rotating frame 41 in the adjusted state. Compared with relying on the self-locking of the drive motor 4, the independent mechanical locking mechanism provides rigid constraint, improving the reliability and long-term stability of angle maintenance, and providing a stable foundation for subsequent splicing processes.

[0055] When the slide bar 44 moves downwards, the fixed connection between the slide bar 44 and the solution chamber 7 causes the solution chamber 7 to move downwards as well. When the sealing plate 72 moves to the position of the fixed wheel 6, the opposite poles of the magnetic plate 1 and magnetic plate 2 74 on one side of the sealing plate 72 are attracted to each other, causing magnetic plate 1 to move the sealing plate 72 toward the position of magnetic plate 2 74. Then, through the movement of the sealing plate 72, it moves away from the bottom of the discharge port 71, allowing the lubricating fluid above the solution chamber 7 to flow downwards from the discharge port 71, then through the through hole 442 into the interior of the guide groove 441, and finally through the guide groove 441 into the outer wall of the slide bar 44, increasing the sliding efficiency. The lubrication of the contact surface between the slide rod 44 and the mounting sleeve 43 reduces friction between them. With the reset spring 73, the sealing plate 72 can be driven back to its original position when it leaves the fixed wheel 6, thus sealing the discharge port 71 again. This structure uses the lifting action of the slide rod 44 itself as the trigger condition, eliminating the need for an additional active control valve or external liquid supply device. This achieves lubrication of the sliding contact surface, reduces frictional resistance and wear, and extends the service life of moving parts. At the same time, the sealing effect of the sealing plate 72 prevents continuous leakage of lubricating fluid, ensuring intermittent lubrication supply and reducing lubricating fluid waste and contamination of other parts of the equipment.

[0056] It should be noted that: because the attraction force between magnetic plate 1 and magnetic plate 2 74 is greater than the elasticity of the return spring 73 itself, a sealing rod is provided at the top of the solution chamber 7. By pulling out the sealing rod, lubricating oil can be added into the solution chamber 7.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

10. A method for intelligent positioning, feeding, and splicing of an integrated log and board machine head, based on the intelligent positioning, feeding, and splicing device for an integrated log and board machine head as described in any one of claims 1-9, characterized in that: The intelligent positioning, feeding, and splicing method for the integrated log and panel machine head includes the following steps: S1: Adsorption and pickup: Simultaneously start the cylinder (3) and vacuum pump (5) to drive the rotating frame (41) to drive the buffer rod (8) and suction cup (52) to descend. The rigid impact is transformed into flexible contact through the buffer rod (8), so that the suction cup (52) adheres to the surface of the wood board in a gradually increasing manner and establishes negative pressure adsorption. S2: Lifting and Transfer: The cylinder (3) drives the rotating frame (41) and suction cup (52) to rise synchronously, completing the vertical lifting of the log board. Combined with the horizontal sliding of the sliding plate (2) on the track frame (1), the log board is transferred from the picking position to the preset splicing station. S3: Edge detection: The edge of the log board is scanned and detected by the sensor (33) installed on the telescopic positioning rod (31) to obtain the board outline or position information and feed it back to the control system; S4: Angle adjustment: Start the motor (4) through the transmission chain of the main shaft (48), mounting sleeve (43), limit block (47), slide rod (44), gear (45) and teeth (46) to drive the rotating frame (41) to rotate the adsorbed plate in the horizontal plane to the preset splicing angle. After completion, start the electric push rod (64) to drive the limit mechanism (62) to insert the fixed wheel (6) and mechanically lock the rotating frame (41). S5: Automatic lubrication: During the descent of the slide rod (44) with the rotating frame (41), the solution chamber (7) moves down synchronously. The sealing plate (72) opens the discharge port (71) due to magnetic force. The lubricant flows through the through hole (442) and the guide groove (441) to the outer wall of the slide rod (44), reducing the friction between the slide rod (44) and the mounting sleeve (43). After the slide rod (44) rises, the reset spring (73) drives the sealing plate (72) to return to its original position and block the discharge port (71), stopping the liquid supply.
