[0033] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0034] 1. This novel liquid metering device for ink processing, based on intelligent sensors, uses a long connecting rod to move the metering body up and down, allowing it to be inserted into the ink for measurement. This facilitates the extraction of different amounts of ink, improving the device's applicability. The sliding seat slides left and right on the adjusting rail to adjust the position of the metering body, adapting to different usage conditions and preventing measurement errors. Rotating the long connecting rod makes the angle between the long and short connecting rods right-angled, allowing the metering body to be stored in the support frame for easy storage. The sliding shaft drives the positioning shaft to slide upwards in the clamping cylinder, causing the positioning shaft to disengage from the clamping cylinder, thus quickly separating the metering body from the long connecting rod. This facilitates inspection of the metering body to ensure measurement accuracy.

[0035] 2. This novel liquid metering device for ink processing based on intelligent sensors pushes two front baffles closer together. The front baffles drive the slider to slide and fit in the slot, protecting the front of the support frame and preventing the metering body from being damaged by impact, which would reduce the measurement accuracy. Then, the dust curtain is lowered to protect the metering body in all directions and prevent dust from falling into the metering body during long-term storage, further preventing the metering body from being affected.

[0036] 3. This novel liquid metering device for ink processing based on intelligent sensors features a connecting plate that drives the lifting frame to slide downwards within the support frame. As the lifting frame slides downwards, it pulls the dust curtain downwards, eliminating the need to pull the dust curtain down individually, thus improving the ease of use of the device. After the long connecting rod is lifted vertically and the pin is released, the spring pulls the pin back to its original position and inserts it into the locking hole at the bottom of the long connecting rod to lock it, preventing the metering device body from loosening and improving the stability of the metering device body when stored.

[0037] 4. This novel liquid metering device for ink processing based on intelligent sensors rotates and lowers the support base, which then contacts the platform below the base. At this time, the support bases on both sides of the base can support the base and support frame, increasing the support area of ​​the device and effectively preventing the device from tipping over during metering, which would cause ink to splash out and affect the metering efficiency. After the support base is limited, it can transmit the force to the force-bearing support rod through the positioning frame, making the support base and the base a fixed whole, improving the support force of the support base, and further promoting the stability of the device during metering.

[0038] 5. This novel liquid metering device for ink processing based on intelligent sensors rotates the positioning frame, causing it to detach from the support base. At this time, the elastic reset action of the first torsion spring causes the support base to rotate and fit against the sides of the base and support frame. Meanwhile, the positioning frame rotates under the influence of the second torsion spring and fits against the bottom of the support frame, reducing the footprint of the device and facilitating movement and storage. The insert plate moves downward and inserts into the positioning frame and slot, thereby locking the support base through the positioning frame to prevent the support base from loosening and improve stability during storage.

Detailed Implementation

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] Please see Figures 1-7One embodiment of the present invention is as follows: a novel liquid metering device for ink processing based on a smart sensor, comprising a base 1, a support frame 2 fixedly connected to the upper surface of the base 1, a linear motor 3 fixedly connected to the rear side of the inner wall of the support frame 2, a metering body 4 disposed on the front side of the linear motor 3, an adjusting slide rail 5 fixedly connected to the front moving end of the linear motor 3, a protective device 8 disposed around the metering body 4 for protecting the metering body 4, a support device 9 disposed on both sides of the metering body 4 for improving stability during the metering process, a long connecting rod 10 driving the metering body 4 to move up and down to insert into the ink for metering, facilitating the extraction of different amounts of ink and improving the applicability of the device, pushing the sliding seat 6 to slide left and right on the adjusting slide rail 5 to adjust the position of the metering body 4 to adapt to different situations during use and avoid metering errors, the support frame 2 including the sliding seat 6, the sliding seat 6 slidably connected to the inner surface of the adjusting slide rail 5, a short connecting rod 7 fixedly connected to the front side of the sliding seat 6, the sliding seat 6 for driving the metering body 4 to move left and right, the long connecting rod The long connecting rod 10 is hinged to the front end of the short connecting rod 7. The long connecting rod 10 is used to drive the measuring instrument body 4 to fold and store. The support frame 2 also includes a rotating shaft 11, which is rotatably connected to the inner surface of the end of the long connecting rod 10 away from the short connecting rod 7. A retaining sleeve 12 is fixedly connected to the top of the rotating shaft 11. A sliding groove 13 is opened at the top of the retaining sleeve 12. A sliding shaft 14 is fixedly connected to the lower circumferential surface of the measuring instrument body 4. A positioning shaft 15 is fixedly connected to the bottom of the sliding shaft 14. The positioning shaft 15 is used for quick installation and removal of the measuring instrument body 4. The positioning shaft 15 and the inner surface of the retaining sleeve 12 are slidably connected. The inner surfaces of the sliding shaft 14 and the sliding groove 13 are slidably connected. The bottom end of the linear motor 3 is fixedly connected to the upper surface of the base 1. A locking hole is provided at the bottom of the long connecting rod 10. Rotating the long connecting rod 10 makes the included angle between the long connecting rod 10 and the short connecting rod 7 a right angle, so that the measuring instrument body 4 can be stored in the support frame 2 for easy storage. The sliding shaft 14 drives the positioning shaft 15 to slide upward in the clamping cylinder 12, so that the positioning shaft 15 is pulled out of the clamping cylinder 12, thereby allowing the measuring instrument body 4 and the long connecting rod 10 to quickly separate, thus facilitating the inspection of the measuring instrument body 4 to ensure measurement accuracy.

[0049] Working principle: When ink needs to be metered, the linear motor 3 is started. The linear motor 3 drives the adjusting slide rail 5 to move up and down. The adjusting slide rail 5, through the sliding seat 6, drives the short connecting rod 7 and the long connecting rod 10 to move up and down. The long connecting rod 10 drives the metering body 4 to move up and down, thus inserting it into the ink for metering. This facilitates the extraction of different amounts of ink, improving the applicability of the device. The sliding seat 6 is pushed to slide left and right on the adjusting slide rail 5, thereby adjusting the position of the metering body 4 to adapt to different situations during use and avoid metering errors. When the metering body 4 is not needed, the long connecting rod 10 is rotated, so that the long connecting rod 10 and the short connecting rod 7... The included angle between the measuring instrument body 4 and the short connecting rod 7 is a right angle, which allows the measuring instrument body 4 to be stored in the support frame 2 for easy storage. During long-term use, when it is necessary to check the measuring instrument body 4 to ensure measuring accuracy, rotate the long connecting rod 10 so that the included angle between the long connecting rod 10 and the short connecting rod 7 is a flat angle. Then push the measuring instrument body 4 upward. The measuring instrument body 4 drives the sliding shaft 14 to slide upward in the sliding groove 13. The sliding shaft 14 then drives the positioning shaft 15 to slide upward in the clamping cylinder 12. Finally, the positioning shaft 15 is pulled out of the clamping cylinder 12, so that the measuring instrument body 4 and the long connecting rod 10 are quickly separated, which facilitates the inspection of the measuring instrument body 4 to ensure measuring accuracy.

[0050] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the protective device 8 includes a front baffle 81, which is disposed on the front side of the support frame 2. Slider blocks 82 are fixedly connected to the upper and lower sides of the inner surface of the front baffle 81. The front baffle 81 is used to prevent the measuring instrument body 4 from being impacted. A slot 83 is opened on the front side of the support frame 2. A dust curtain 84 is rolled up on the lower top surface of the support frame 2. The dust curtain 84 is used to prevent dust from adhering to the measuring instrument body 4. Pushing the two front baffles 81 closer together causes the sliders 82 to slide and fit within the slot 83, thus protecting the front of the support frame 2 and preventing the measuring instrument body 4 from being damaged by impact, which could lead to a decrease in measuring accuracy. Then, the dust curtain 84 is lowered, providing all-around protection for the measuring instrument body 4 and preventing dust from falling into the measuring instrument body 4 during long-term storage, further preventing the measuring instrument body 4 from being affected. The protective device 8 also includes a connecting plate 85, which is fixedly connected to both sides of the adjusting slide rail 5. A lifting frame 8... The sliding block 86 is slidably connected to the inner surface of the support frame 2. The lifting frame 86 is used to drive the dust curtain 84 to unfold or retract. The limiting plate 87 is fixedly connected to the front side of the sliding block 6. The inner surface of the limiting plate 87 is slidably connected to the pin 88, which is used to lock the long connecting rod 10, thereby quickly locking the measuring instrument body 4. The inner surfaces of the slider 82 and the slot 83 are slidably connected. The bottom end of the dust curtain 84 is fixedly connected to the upper surface of the lifting frame 86. The end of the connecting plate 85 away from the adjusting slide rail 5 is fixedly connected to the inner surface of the lifting frame 86. A spring is provided between the pin 88 and the limiting plate 87. The connecting plate 85 drives the lifting frame 86 to slide downward in the support frame 2. When the lifting frame 86 slides downward, it pulls the dust curtain 84 to unfold downward. There is no need to pull the dust curtain 84 down individually, which improves the ease of use of the device. After the long connecting rod 10 is lifted vertically, the pin 88 is released. The spring pulls the pin 88 to reset and insert it into the locking hole at the bottom of the long connecting rod 10 to lock it, preventing the measuring instrument body 4 from loosening and improving the stability of the measuring instrument body 4 when stored.

[0051] Working principle: When the device is not in use, rotating the long connecting rod 10 retracts the measuring instrument body 4 into the support frame 2, pushing the two front baffles 81 closer together. The front baffles 81 drive the slider 82 to slide and fit in the slot 83, protecting the front of the support frame 2 and preventing the measuring instrument body 4 from being damaged by impact, which would reduce the accuracy of measurement. Then, the dust curtain 84 is lowered, thus providing all-round protection for the measuring instrument body 4 and preventing dust from falling into the measuring instrument body 4 during long-term storage, further preventing the measuring instrument body 4 from being affected. The linear motor 3 is started, and the linear motor 3 drives the adjusting slide rail 5 to move downwards. 5. The lifting frame 86 is driven to slide downward within the support frame 2 by the connecting plate 85. When the lifting frame 86 slides downward, it pulls the dust curtain 84 downward to unfold. There is no need to pull the dust curtain 84 down individually, which improves the ease of use of the device. Before the measuring instrument body 4 is put into the support frame 2, the pin 88 is pulled to the left. The pin 88 drives the spring to stretch, and the long connecting rod 10 is lifted vertically. Then the pin 88 is released. The elastic reset action of the spring pulls the pin 88 to slide to the right within the limiting plate 87 and inserts it into the locking hole at the bottom of the long connecting rod 10 to lock it, preventing the measuring instrument body 4 from loosening and improving the stability of the measuring instrument body 4 when stored.

[0052] Please see Figures 1-7In another embodiment of the present invention, based on the above embodiments, the support device 9 includes a support base 91, which is hinged to both sides of the base 1. The support base 91 is used to support the base 1 and the support frame 2, increasing the support area of ​​the device. A force-bearing rod 92 is fixedly connected to both sides of the base 1. A positioning frame 93 is hinged to the end of the force-bearing rod 92 away from the base 1. When the support base 91 is rotated down and contacts the platform below the base 1, the support bases 91 on both sides of the base 1 can support the base 1 and the support frame 2, increasing the support area of ​​the device and effectively preventing the device from tipping over during measurement, which would cause ink to splash out and affect the measurement efficiency. After the support base 91 is limited, it can transmit the force to the force-bearing rod 92 through the positioning frame 93, making the support base 91 and the base 1 a fixed whole, increasing the support force of the support base 91, and further promoting the stability of the device during measurement. The support device 9 also includes a groove 94, which is formed on the base 1. On both sides of the surface, slots 95 are provided on the inner bottom surface of the groove 94. The locking frame 96 is fixedly connected to the upper surface of the support base 91, and the insert plate 97 is fixedly connected to both sides of the lower surface of the lifting frame 86. The insert plate 97 is used to lock the locking frame 96 in the groove 94, thereby fixing the support base 91 in a state of contact with the support frame 2. A torsion spring is provided at the hinge of the support base 91 and the base 1, and a torsion spring is provided at the hinge of the positioning frame 93 and the force-bearing support rod 92. Rotating the positioning frame 93 causes it to disengage from the support base 91. At this time, the elastic restoring effect of the torsion spring 1 drives the support base 91 to rotate and contact the sides of the base 1 and the support frame 2. The positioning frame 93 rotates under the influence of the torsion spring 2 and contacts the bottom of the support frame 2, reducing the area occupied by the device and facilitating movement and storage. The insert plate 97 moves downward and inserts into the positioning frame 93 and the slot 95, thereby locking the support base 91 through the positioning frame 93, preventing the support base 91 from loosening and improving the stability during storage.

[0053] Working Principle: Before using the device, rotate and lower the support base 91 until it contacts the platform below the base 1. At this time, the support bases 91 on both sides of the base 1 can support the base 1 and the support frame 2, increasing the support area of ​​the device and effectively preventing the device from tipping over during measurement, which would cause ink to splatter and affect the measurement efficiency. Rotate the positioning frame 93 to make the support base 91 snap into the positioning frame 93. At this time, the positioning frame 93 is clamped by the torsion force of the torsion spring. After the support base 91 is limited, it can transmit the force through the positioning frame 93 to the force-bearing support rod 92, making the support base 91 and the base 1 a fixed whole, increasing the support force of the support base 91, and further promoting the measurement efficiency of the device. For stability, when the device is not in use, rotating the positioning frame 93 disengages it from the support base 91. At this time, the elastic restoring action of the first torsion spring causes the support base 91 to rotate and fit against the sides of the base 1 and the support frame 2. Meanwhile, the positioning frame 93 rotates under the influence of the second torsion spring and fits against the bottom of the support frame 2, reducing the area occupied by the device and facilitating movement and storage. When the support base 91 fits against the sides of the support frame 2, it causes the locking frame 96 to rotate and insert into the groove 94. At the same time, the lifting frame 86 slides downward, causing the insert plate 97 to move downward and insert into the positioning frame 93 and the slot 95. Thus, the positioning frame 93 locks the support base 91, preventing it from loosening and improving stability during storage.
