[0002] The proportioning device is an important piece of equipment in the production process. By controlling the input and output of different raw materials, it can achieve the function of precise proportioning of products, thereby ensuring the accuracy of product ratio and composition.

[0003] Chinese Patent Publication No. CN113117593A discloses a multi-component automatic precision color matching system and its working method, including a batching silo, a main material silo, a weighing silo, an intermediate silo, and a discharge silo. It includes a first discharge device in the batching silo, a second discharge device in the main material silo, a third discharge device in the weighing silo, a fourth discharge device in the intermediate silo, and a fifth discharge device in the discharge silo. It also includes a PLC controller and a human-machine interface device electrically connected to the PLC controller. This color matching system includes an electronic weighing instrument and has the effect of improving the production efficiency of automated color matching production processes. While the above device can improve production efficiency, during the mixing process, it cannot simultaneously adjust the feeding amount or feeding sequence of different feeding zones, resulting in low adjustability. Summary of the Invention

[0004] This invention proposes an automatic proportioning device and method, which can adjust the feeding amount or feeding sequence of different feeding cylinders while feeding synchronously.

[0005] The technical solution of the present invention is as follows:

A mixing cylinder is connected below the first and second connecting cylinders, and a first extension cylinder is connected below the mixing cylinder. A second extension cylinder is located to the right of the first extension cylinder. Sliding components are installed inside each of the first, first, second, third, fourth, and second extension cylinders. A first pressure rod is positioned above the sliding components, and an overlapping plate is fixedly connected to the first pressure rod.

[0008] As a preferred embodiment of the present invention, the drive assembly includes a first fixed rod fixedly installed on the upper and lower sides of the first baffle, an outer bushing slidably installed on the outer side of the first fixed rod, a bolt threaded on the outer bushing, a motor fixedly disposed between the two outer bushings, and a first key rod fixedly disposed on the output shaft of the motor, the first key rod and the central axis of the first synchronous pulley being collinear.

[0009] As a preferred embodiment of the present invention, both the rotating rod and the partition are made of magnetic metal, and the magnetic blocks are stacked between adjacent partitions.

[0010] As a preferred embodiment of the present invention, the synchronization component includes a second fixed rod fixedly mounted on the second baffle, a slide plate slidably mounted on the second fixed rod, a second key rod rotatably mounted in the middle of the slide plate, and the central axis of the second key rod being collinear with the central axis of the second synchronization wheel.

[0011] As a preferred embodiment of the present invention, a connecting assembly is installed on the side of both the first extension cylinder and the second extension cylinder. The connecting assembly includes a cover plate and a fixing ring. The cover plate is hinged to the side of the first extension cylinder, and the fixing ring is fixedly disposed on the first extension cylinder. In the second extension cylinder and the connecting assembly, the cover plate is hinged to the side of the second extension cylinder, and the fixing ring is fixedly disposed on the second extension cylinder. A retaining rod is provided through the interior of the fixing ring and the cover plate.

[0012] As a preferred embodiment of the present invention, the sliding assembly includes a groove formed on the first connecting cylinder, the first extension cylinder, the second connecting cylinder, the third connecting cylinder, the fourth connecting cylinder, or the second extension cylinder. A front plate is slidably installed in the groove. A connecting plate is fixedly disposed on the rear side of the front plate. A second pressure plate is fixedly disposed on the rear side of the connecting plate. A first pressure plate is fixedly disposed on the rear side of the second pressure plate. A tension rope is connected between the front plate and the corresponding first connecting cylinder, the corresponding first extension cylinder, the corresponding second connecting cylinder, the corresponding third connecting cylinder, the corresponding fourth connecting cylinder, or the corresponding second extension cylinder. The first pressure rod abuts against the upper part of the front plate on the first connecting cylinder, the second connecting cylinder, the third connecting cylinder, and the fourth connecting cylinder.

[0013] As a preferred embodiment of the present invention, a second pressure bar is installed on the overlapping plate, and the second pressure bar abuts against the upper part of the front plate on the first extension cylinder and the second extension cylinder;

[0014] Alternatively, it may include a second pressure rod drive unit, on which a second pressure rod is mounted, and the second pressure rod drive unit drives the second pressure rod to move up and down, with the second pressure rod abutting against the top of the front plate on the first extension cylinder and the second extension cylinder.

[0015] In a preferred embodiment of the present invention, the transmission assembly includes a third synchronous pulley and a fourth synchronous pulley rotatably mounted inside the first pressure plate. The third synchronous pulley is connected to the fourth synchronous pulley via a third synchronous belt, which protrudes from the surface of the first pressure plate. A damping shaft is rotatably mounted inside the fourth synchronous pulley. A gear is fixedly mounted on the damping shaft, and a rack is meshed above the gear. A third baffle is fixedly mounted on the rack, and the third baffle and the second pressure plate are slidably connected. The third synchronous belt is adapted to rotate when the first pressure plate moves downward or in the opposite direction when it moves upward.

[0016] As a preferred embodiment of the present invention, the third baffle and the second pressure plate are slidably connected, and the upper surface of the second pressure plate is inclined.

[0017] This invention also describes a method of using an automatic proportioning device, comprising the following steps:

[0018] S1: Lift the sliding components inside the first connecting cylinder, the first extension cylinder, the second connecting cylinder, the third connecting cylinder, the fourth connecting cylinder, and the second extension cylinder. During the upward movement of the sliding components, the transmission component causes the opening in the middle of the sliding components to open automatically, allowing different raw materials to be poured into the interior of the first connecting cylinder, the second connecting cylinder, the third connecting cylinder, and the fourth connecting cylinder.

[0019] S2: When the sliding component moves downward, the transmission component causes the opening in the middle of the sliding component to close automatically. The raw material is squeezed and compacted, and the raw material is piled up between two adjacent partitions. By installing different numbers of magnetic blocks between two adjacent partitions, the material feed amount in the first, second, third, and fourth connecting cylinders will be different after the rotating rod inside the first, second, third, and fourth connecting cylinders rotates one revolution. This changes the ratio of different raw materials, or fills the space between two partitions at different positions with magnetic blocks to change the feeding order of different connecting cylinders.

[0020] S3: Connect the synchronization component to the second synchronization wheel. The second synchronization wheel and the first synchronization wheel rotate synchronously under the action of the first synchronization belt. After the first baffle and the second baffle are closed, the rotating rods in the connecting cylinders at different positions rotate synchronously to change the number of activation areas of the ratio zone.

[0021] S4: After the single mixing is completed, the raw materials will enter the interior of the first extension cylinder and the second extension cylinder through the mixing cylinder, and the secondary mixing work will be completed from the bottom of the first extension cylinder and the second extension cylinder.

[0022] The working principle and beneficial effects of this invention are as follows:

[0023] 1. By using a rotating rod, partitions, and magnetic blocks, the partitions rotate synchronously with the rotating rod when different numbers of magnetic blocks are installed, and the amount of feed changes. When the spaces in the two partitions in different areas are filled, the feeding sequence changes when the rotating rod rotates. This device can change the feeding ratio and feeding sequence by changing the number of magnetic blocks installed in different connecting cylinders and the position of the magnetic blocks in different connecting cylinders. This solves the problem that existing proportioning devices cannot adjust the feeding amount or feeding sequence of feeding cylinders in different areas while feeding synchronously. This device has the advantage of a higher degree of adjustability.

[0024] 2. Through the electric push rod, the first pressure rod, and the second pressure rod on the device, when the electric push rod shortens, the sliding components at each position move downward synchronously. While the sliding components move downward, the raw materials in the device can be compacted. The tension rope facilitates the subsequent lifting and resetting of the sliding rod components, so that the device can ensure the compactness of the material while feeding, thereby ensuring the accuracy of the proportioning. This solves the defect of existing proportioning devices where the accuracy of the proportioning is affected by the different degrees of looseness of the material after feeding.

[0025] 3. With the feeding assembly in place, the front plate can move downwards synchronously and close the chute as the feeding assembly moves downwards, ensuring that the feeding assembly located inside the cylinder remains closed while moving downwards, thereby preventing raw material leakage and enhancing the stability of the device during operation.

[0026] 4. Through the transmission components, as the sliding component slides downward, the third synchronous belt is squeezed and rotates, driving the gear to rotate and the rack to move, thereby automatically closing the opening in the middle of the sliding component. When the sliding component moves upward and resets, the third synchronous belt rotates in the opposite direction, thereby automatically opening the opening in the middle of the sliding component, facilitating the subsequent replenishment of proportioned raw materials.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] like Figures 1-9As shown, this embodiment proposes an automatic mixing device, including a first connecting cylinder 1, a second connecting cylinder 4 disposed to the right side of the first connecting cylinder 1, a third connecting cylinder 5 disposed to the right side of the second connecting cylinder 4, a fourth connecting cylinder 6 disposed to the right side of the third connecting cylinder 5, a mixing cylinder 2 disposed below the first connecting cylinder 1 and the second connecting cylinder 4, a first extension cylinder 3 disposed below the mixing cylinder 2, a second extension cylinder 18 disposed to the right side of the first extension cylinder 3, and connecting components 19 installed on the sides of both the first extension cylinder 3 and the second extension cylinder 18. Sliding components 24 are installed inside the first connecting cylinder 1, the first extension cylinder 3, the second connecting cylinder 4, the third connecting cylinder 5, the fourth connecting cylinder 6, and the second extension cylinder 18. After the first connecting cylinder 1, the second connecting cylinder 4, the third connecting cylinder 5, and the fourth connecting cylinder 6 complete one mixing cycle, the first extension cylinder 3 and the second extension cylinder 18 can complete the second mixing cycle. A first pressure rod 20 is installed above the sliding assembly 24, and an overlapping plate 21 is fixedly connected to the first pressure rod 20. A second pressure rod 22 is installed on the overlapping plate 21, and an electric push rod 23 is installed below the overlapping plate 21. When the electric push rod 23 shortens, the first pressure rod 20 and the second pressure rod 22 move downwards, thereby keeping the raw materials in the device compacted before mixing, thus ensuring mixing accuracy. The electric push rod 23 and the second extension cylinder 18 are fixedly connected. A transmission assembly 25 is installed inside the sliding assembly 24. 4. During the downward movement, the transmission component 25 can close the originally open port. When the sliding component 24 moves upward, the transmission component 25 reopens the port in the middle of the sliding component 24 to replenish the required proportion of raw materials. A first baffle 7 is slidably installed at the bottom of the first connecting cylinder 1. A drive component 8 is installed on the first baffle 7. A first synchronous wheel 12 is rotatably installed in the middle of the first baffle 7. A rotating rod 9 is rotatably installed inside the first connecting cylinder 1. Multiple partitions 10 are fixedly arranged around the rotating rod 9. A magnetic block 11 is fixedly arranged between two adjacent partitions 10. The drive component 8 can drive the rotating rod 9 to rotate. The rotating rod 9 drives the partitions 10 to rotate, thereby realizing the automatic feeding function. The number of magnetic blocks 11 installed between the partitions 10 can be changed, or magnetic blocks 11 can be filled between two partitions 10, thereby changing the feeding sequence of different connecting cylinders. The bottom of the second connecting cylinder 4, the third connecting cylinder 5 and the fourth connecting cylinder 6 are all slidably installed with a second baffle 14. A second synchronous wheel 15 is rotatably installed in the middle of the second baffle 14. A first synchronous belt 13 is installed between the first synchronous wheel 12 and the second synchronous wheel 15. A second synchronous belt 16 is installed between two adjacent second synchronous wheels 15. A synchronization component 17 is installed on the second baffle 14. The synchronization component 17 can change the number of working connecting cylinders. When there are fewer types of raw materials that need to be mixed, some connecting cylinders can be closed, thereby reducing the working intensity of the drive component 8.

[0041] In this embodiment, the internal structures of the first connecting cylinder 1, the first extending cylinder 3, the second connecting cylinder 4, the third connecting cylinder 5, the fourth connecting cylinder 6, and the second extending cylinder 18 are the same. The connection method between the fourth connecting cylinder 6 and the second extending cylinder 18 is the same as the connection method between the first extending cylinder 3 and the second connecting cylinder 4. After the raw materials in the first connecting cylinder 1, the second connecting cylinder 4, the third connecting cylinder 5, and the fourth connecting cylinder 6 fall down, the raw materials in the first extending cylinder 3 and the second extending cylinder 18 can complete the secondary proportioning, which enhances the function of the device. The bottom structure of the first extending cylinder 3 is the same as the bottom structure of the first connecting cylinder 1, and the bottom structure of the second extending cylinder 18 is the same as the bottom structure of the second connecting cylinder 4. The material can achieve the secondary proportioning function through the bottom structure of the first extending cylinder 3 and the second extending cylinder 18.

[0042] In this embodiment, the drive assembly 8 includes a first fixing rod 801 fixedly installed on the upper and lower sides of the first baffle 7. An outer bushing 802 is slidably installed on the outer side of the first fixing rod 801. A bolt 803 is threaded on the outer bushing 802. A motor 804 is fixedly arranged between the two outer bushings 802. A first key rod 805 is fixedly arranged on the output shaft of the motor 804. The central axis of the first key rod 805 and the first synchronous pulley 12 are collinear. By moving the outer bushing 802, the front and rear positions of the motor 804 and the first key rod 805 are changed, so that the first key rod 805 is inserted into the first synchronous pulley 12 so that the first synchronous pulley 12 can be driven to rotate subsequently. The bolt 803 can be fixed after the outer bushing 802 is moved to a suitable position.

[0043] In this embodiment, both the rotating rod 9 and the partition 10 are made of magnetic metal. The magnetic blocks 11 are stacked between two adjacent partitions 10 to ensure that the magnetic blocks 11 can remain fixed after installation. The magnetic blocks 11 can be stably adsorbed on the partition 10 to ensure the stability of the device during operation.

[0044] In this embodiment, the synchronization component 17 includes a second fixed rod 1701 fixedly installed on the second baffle 14. A slide plate 1702 is slidably installed on the second fixed rod 1701. A second key rod 1703 is rotatably installed in the middle of the slide plate 1702. The central axis of the second key rod 1703 is collinear with the central axis of the second synchronization wheel 15. By sliding the slide plate 1702, the second key rod 1703 is connected to the second synchronization wheel 15, so that the rotation of the second synchronization wheel 15 drives the second key rod 1703 to rotate, so as to change the number of connecting cylinders activated in the future.

[0045] In this embodiment, the connecting component 19 includes a cover plate 1901 and a fixing ring 1902. In the connecting component 19 on the side of the first extension cylinder 3, the cover plate 1901 is hinged to the side of the first extension cylinder 3, and the fixing ring 1902 is fixedly disposed on the first extension cylinder 3. In the connecting component 19 on the side of the second extension cylinder 18, the cover plate 1901 is hinged to the side of the second extension cylinder 18, and the fixing ring 1902 is fixedly disposed on the second extension cylinder 18. A locking rod 1903 is provided through the interior of the fixing ring 1902 and the cover plate 1901. By removing the locking rod 1903 and opening the cover plate 1901 on the first extension cylinder 3 and the second extension cylinder 18, it is convenient to observe the internal condition of the first extension cylinder 3 and the second extension cylinder 18 or to add corresponding raw materials to the interior of the first extension cylinder 3 and the second extension cylinder 18.

[0046] In this embodiment, the sliding assembly 24 includes a groove 2406 formed on the first connecting cylinder 1, the first extension cylinder 3, the second connecting cylinder 4, the third connecting cylinder 5, the fourth connecting cylinder 6, or the second extension cylinder 18. A front plate 2404 is slidably installed in the groove 2406. A connecting plate 2403 is fixedly disposed on the rear side of the front plate 2404. A second pressure plate 2402 is fixedly disposed on the rear side of the connecting plate 2403. A first pressure plate 2401 is fixedly disposed on the rear side of the second pressure plate 2402. A tension rope 2405 is connected between the front plate 2404 and the corresponding first connecting cylinder 1, the corresponding first extension cylinder 3, the corresponding second connecting cylinder 4, the corresponding third connecting cylinder 5, the corresponding fourth connecting cylinder 6, or the corresponding second extension cylinder 18. When the sliding assembly 24 moves downward as a whole... The front plate 2404 can block the lower half of the chute 2406 to prevent raw material leakage. When the first pressure plate 2401, the second pressure plate 2402 and the connecting plate 2403 move downward as a whole, they can compact the corresponding material to ensure the accuracy of subsequent proportioning. The first pressure rod 20 abuts against the upper part of the front plate 2404 on the first connecting cylinder 1, the second connecting cylinder 4, the third connecting cylinder 5 and the fourth connecting cylinder 6. When the first pressure rod 20 moves downward, it presses down the material in the first connecting cylinder 1 or the second connecting cylinder 4 or the third connecting cylinder 5 or the fourth connecting cylinder 6. The second pressure rod 22 abuts against the upper part of the front plate 2404 on the first extension cylinder 3 and the second extension cylinder 18. When the second pressure rod 22 moves downward, it presses down the material in the first extension cylinder 3 or the second extension cylinder 18.

[0047] In this embodiment, the transmission assembly 25 includes a third synchronous pulley 2502 and a fourth synchronous pulley 2503 rotatably mounted inside the first pressure plate 2401. The third synchronous pulley 2502 is connected to the fourth synchronous pulley 2503 via a third synchronous belt 2501, which protrudes from the surface of the first pressure plate 2401. A damping shaft 2507 is rotatably mounted inside the fourth synchronous pulley 2503. A gear 2504 is fixedly mounted on the damping shaft 2507, and a rack 2505 is meshed above the gear 2504. A third baffle 2506 is fixedly installed on the 05, and the third baffle 2506 is slidably connected to the second pressure plate 2402. Since the third synchronous belt 2501 is adapted to rotate when the first pressure plate 2401 moves downward or in the opposite direction when it moves upward, it can be specifically configured as follows: the side of the third synchronous belt 2501 is pressed against the inner wall of the corresponding cylinder, and there is friction between the third synchronous belt 2501 and the inner wall of the cylinder. As the third synchronous belt 2501 moves up and down with the first pressure plate 2401, the third synchronous belt 2501 rotates. Figure 9 As shown, the third synchronous belt 2501 abuts against the inner wall of the first connecting cylinder 1, the second connecting cylinder 4, the third connecting cylinder 5, or the fourth connecting cylinder 6. When the first pressure plate 2401 moves downward, the third synchronous belt 2501 rotates, thereby driving the third synchronous wheel 2502 and the fourth synchronous wheel 2503 to rotate. The rotation of the gear 2504 will drive the rack 2505 and the third baffle 2506 to move. The two adjacent third baffles 2506 move closer to each other, thereby automatically closing the feed inlet. At this time, the raw material can be compacted.

[0048] In this embodiment, the third baffle 2506 and the second pressure plate 2402 are slidably connected, and the upper surface of the second pressure plate 2402 is inclined. Figure 5 As can be seen from the image, the inclined second pressure plate 2402 facilitates automatic feeding of raw materials and avoids excessive accumulation of raw materials on the surface of the second pressure plate 2402.

[0049] Specifically, firstly, such as Figures 1-7 As shown, by extending the electric push rod 23, the first pressure rod 20, the overlapping plate 21, and the second pressure rod 22 move upward. Under the action of the tension rope 2405, the sliding assembly 24 inside the first connecting cylinder 1, the first extension cylinder 3, the second connecting cylinder 4, the third connecting cylinder 5, the fourth connecting cylinder 6, and the second extension cylinder 18 moves upward. During the upward movement of the sliding assembly 24, as... Figure 9As shown, when the first pressure plate 2401 moves upward, the third synchronous belt 2501 maintains a pressing state with the inner walls of the first connecting cylinder 1, the first extension cylinder 3, the second connecting cylinder 4, the third connecting cylinder 5, the fourth connecting cylinder 6, and the second extension cylinder 18. As the first pressure plate 2401 moves upward, the third synchronous belt 2501 will abut against the inner wall of the cylinder and rotate, thereby driving the third synchronous wheel 2502 and the fourth synchronous wheel 2503 to rotate. The gear 2504 rotates synchronously, driving the rack 2505 and the third baffle 2506 to move. The two adjacent third baffles 2506 move away from each other, thereby causing the feed port to open automatically. At this time, the feed port in the middle of the sliding assembly 24 opens automatically, pouring different raw materials into the interior of the first connecting cylinder 1, the second connecting cylinder 4, the third connecting cylinder 5, and the fourth connecting cylinder 6.

[0050] like Figures 6-9 As shown, when the sliding component 24 moves downward, the transmission component 25 causes the feed port between the two third baffles 2506 of the sliding component 24 to automatically close, as... Figure 9 As shown, when the first pressure plate 2401 moves downward, the tension rope 2405 is stretched, the third synchronous belt 2501 is squeezed and rotated, thereby driving the third synchronous wheel 2502 and the fourth synchronous wheel 2503 to rotate clockwise. The gear 2504 rotates clockwise, driving the rack 2505 and the third baffle 2506 to move. The two adjacent third baffles 2506 move closer to each other, and the feed port is automatically closed. As the sliding component 24 continues to move downward, the raw material is squeezed and compacted, and the raw material is piled up between the two adjacent partitions 10. By installing different numbers of magnetic blocks 11 between the two adjacent partitions 10, the material feed amount in the different connecting cylinders will be different after the rotating rod 9 inside the first connecting cylinder 1, the second connecting cylinder 4, the third connecting cylinder 5 and the fourth connecting cylinder 6 rotates one revolution, thereby changing the raw material ratio during feeding. Alternatively, magnetic blocks 11 can be filled between the two partitions 10 at different positions in each connecting cylinder and the extension cylinder, thereby changing the feeding order of the different connecting cylinders.

[0051] In this embodiment, for a certain material, when the magnetic block 11 is not installed, the mass of the material between the two partitions 10 is fixed in the compacted state, and the mass of the material between the two partitions 10 can be adjusted by adjusting the magnetic block 11 between the two partitions 10.

[0052] like Figures 1-4As shown, the device can achieve auxiliary feeding by pulling out the lever 1903 on the connecting component 19 and opening the cover plate 1901 on the first extension cylinder 3 and the second extension cylinder 18, so that the cover plate 1901 is separated from the fixing ring 1902, allowing observation of the internal condition of the first extension cylinder 3 and the second extension cylinder 18 or adding corresponding raw materials into the first extension cylinder 3 and the second extension cylinder 18. During operation, the first baffle 7 is closed, and the front and rear positions of the motor 804 and the first key rod 805 are changed by sliding the outer bushing 802 on the drive component 8. The bolt 803 can be fixed after the outer bushing 802 moves to the appropriate position. At the same time, the first key rod 805 moves into the interior of the first synchronous wheel 12 and the rotating rod 9. The first key rod 805 is keyed to the first synchronous wheel 12 and the rotating rod 9 in the first connecting cylinder 1, so that when the motor 804 drives the first key rod 805 and the rotating rod 9 to rotate, the rotating rod 9 rotates and drives the partition plate 10 and the magnetic block 11 to rotate, thereby achieving the function of quantitative feeding. After the second baffle 14 is closed, the second key rod 1703 on the synchronization component 17 is connected to the rotating rod 9 inside the second synchronization wheel 15 and the second connecting cylinder 4. The second synchronization wheel 15 and the first synchronization wheel 12 rotate synchronously under the action of the first synchronization belt 13. After the first baffle 7 and the second baffle 14 are closed, after the material passes under the first connecting cylinder 1 and the second connecting cylinder 4 and under the third connecting cylinder 5 and the fourth connecting cylinder 6 to complete the first proportioning, since the bottom structure of the first extension cylinder 3 and the second extension cylinder 18 is the same as the bottom structure of the first connecting cylinder 1 and the second connecting cylinder 4, the raw material will enter the interior of the first extension cylinder 3 and the second extension cylinder 18 through the mixing cylinder 2, and finally exit from the bottom of the first extension cylinder 3 and the second extension cylinder 18 to complete the second proportioning. The principle of the second proportioning is the same as the principle of the first proportioning of the first connecting cylinder 1 and the second connecting cylinder 4, and will not be described in detail in this embodiment.

[0053] Example 2

[0054] The structure of this embodiment is basically the same as that of Embodiment 1, except that the second pressure rod 22 in this embodiment is not driven by the electric push rod 23. The automatic proportioning device in this embodiment also includes a second pressure rod drive component, which can be a pneumatic cylinder or a hydraulic cylinder. The second pressure rod 22 is mounted on the second pressure rod drive component, which drives the second pressure rod 22 to move up and down. The second pressure rod 22 abuts against the upper part of the front plate 2404 on the first extension cylinder 3 and the second extension cylinder 18. The movement of the second pressure rod 22 is driven independently by the second pressure rod drive component.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
