Description

Technical Field

[0001] This invention belongs to the field of liquid level measurement technology, specifically a green, low-carbon, water-based cutting fluid production liquid level measurement device. Background Technology

[0002] Green, low-carbon water-based cutting fluid is an environmentally friendly metalworking fluid that, based on traditional water-soluble cutting fluids, achieves lower environmental impact and carbon emissions throughout its production, use, and disposal processes through optimized formulation, raw materials, and lifecycle management. During production, this cutting fluid is typically stored in plastic drums. After filling, the fluid level in the drums must be measured to ensure it meets standards.

[0003] Patent CN108955824A discloses a liquid level measuring device. The device includes a straight pipe fixed to a support by clamps and bolts. An inlet is located at the lower part of the straight pipe, and an ultrasonic level gauge is mounted above it. The ultrasonic level gauge is fixed to the middle of a crossbeam, which is also fixed to the support by bolts. A square protective cover is provided above the ultrasonic level gauge, and an arc-shaped protective cover is provided below the sensing part of the gauge. An opening corresponding to the position of the sensing part of the ultrasonic level gauge is located below the arc-shaped protective cover. This patent features a simple structure, ease of use, long service life, and low investment cost, effectively solving the problem of large measurement fluctuations and inaccuracies caused by liquid level fluctuations in ultrasonic level gauges.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] The ultrasonic level sensor is aligned with the cutting fluid in the container to measure its level. When measuring the cutting fluid levels in multiple containers, to improve efficiency, the plastic containers filled with cutting fluid are typically placed on a conveyor roller, which moves them to the level of the ultrasonic level sensor. However, when the conveyor roller moves the plastic containers, uneven force can cause them to deviate, preventing them from accurately reaching the sensor along a preset trajectory, thus affecting the measurement. Summary of the Invention

[0006] To overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a green, low-carbon, water-based cutting fluid production level measuring device.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a green low-carbon water-based cutting fluid production liquid level measuring device, including a frame, on which multiple conveying rollers are arranged;

[0008] It also includes a barrel guide assembly;

[0009] The barrel guide assembly includes a support frame fixedly connected to one side of the frame. Two limiting plates 1 and multiple limiting plates 2 are sleeved on the support frame, and the limiting plates 2 are located between the two limiting plates 1. The limiting plate 1 on the left is fixedly connected to the support frame, the limiting plate 1 on the right is slidably connected to the support frame, and the limiting plate 2 is slidably connected to the support frame.

[0010] Mounting base 2 is fixedly connected to the first limiting plate and multiple second limiting plates on the left side. An ultrasonic liquid level sensor is provided on one side of the bottom of the second mounting base. A baffle is fixedly connected to the end of the frame. A control panel is provided on one side of the frame.

[0011] Preferably, each of the two limiting plates is rotatably provided with a connecting rod 1 at its upper end, and the limiting plate 2 is rotatably provided with a connecting rod 2 at its upper end. One end of the connecting rod 1 is rotatably connected to one end of the connecting rod 2, and the ends of two adjacent connecting rods 2 are rotatably connected.

[0012] Preferably, a cylinder is fixedly connected to one side of the support frame, and the piston end of the cylinder is fixedly connected to one side of the right limiting plate.

[0013] Preferably, a mounting base is fixedly connected to each of the first limiting plate and multiple second limiting plates on the right side, and an infrared probe is provided on one side of the bottom of the mounting base.

[0014] Preferably, a support block is fixedly connected to each of the first limiting plate and multiple second limiting plates on the left side, and a blocking block is rotatably provided on one side of the upper end of each support block.

[0015] Preferably, a motor is fixedly connected to one side of the support block, and the output end of the motor is fixedly connected to one end of the blocking block.

[0016] Preferably, it also includes an anti-jamming deflection component;

[0017] The anti-jamming deflection assembly includes a groove on one side of the limiting plate, a push rod slidably passing through the groove, a movable rod fixedly connected to one end of the push rod, and a friction roller rotatably mounted on one end of the movable rod.

[0018] Preferably, a second cylinder is fixedly connected to one side of the limiting plate, and the piston end of the second cylinder is fixedly connected to one end of the push rod.

[0019] Preferably, one end of the moving rod is fixedly connected to a second motor, and the output end of the second motor is fixedly connected to one end of the friction roller.

[0020] Preferably, it also includes splash-proof components;

[0021] The splash-proof assembly includes multiple fixed blocks fixedly connected to the frame. A lead screw is rotatably mounted on the upper end of one of the fixed blocks, and slide rods are fixedly connected to the upper ends of the other fixed blocks. A cover plate is slidably connected to the slide rods. One side of the cover plate is threadedly connected to the lead screw. A motor is fixedly connected to the bottom of one of the fixed blocks, and one end of the lead screw is fixedly connected to the output end of the motor.

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

[0023] 1. The green, low-carbon, water-based cutting fluid production level measuring device of this invention utilizes a barrel guiding assembly. Multiple plastic barrels are simply placed on a conveying roller, and under the guidance of limiting plates one and two, they move in an orderly manner under the ultrasonic level sensor for measurement. This avoids the situation where the plastic barrels deviate due to uneven force during conveying, failing to accurately reach the ultrasonic level sensor along a preset trajectory, thus affecting normal measurement. Furthermore, the multi-channel design allows for simultaneous measurement of the cutting fluid level in multiple plastic barrels, improving measurement efficiency.

[0024] 2. The green, low-carbon, water-based cutting fluid production level measuring device of this invention utilizes an anti-jamming deflection component. During the movement of the plastic bucket, the friction roller continuously rotates. When the plastic bucket reaches one end of the limit plate, it deflects due to contact with the rotating friction roller, thus smoothly entering the conveying channel and ensuring the smooth progress of subsequent measurements. Furthermore, while the friction roller rotates, the push rod slides back and forth in the groove, allowing the friction roller to push the plastic bucket, separating two abutting plastic buckets. The separated plastic buckets can then continue to move under the action of the conveying roller and smoothly enter the conveying channel. This avoids the situation where two plastic buckets are stuck at the entrance of the conveying channel in an abutting state and cannot be released by the rotation of the friction roller, thus affecting the normal operation of subsequent measurements.

[0025] 3. The green, low-carbon, water-based cutting fluid production level measuring device of the present invention utilizes a splash-proof component. Based on the height of the plastic bucket, a motor drives a lead screw to rotate, thereby raising and lowering the cover plate. This allows the cover plate to cover the opening of the plastic bucket without affecting its transport. As the plastic bucket is pushed, the opening remains covered, effectively preventing cutting fluid from splashing out and ensuring subsequent measurement accuracy. Attached Figure Description

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please refer to Figures 1-8 The present invention provides a technical solution: a green low-carbon water-based cutting fluid production liquid level measuring device, including a frame 1, on which a plurality of conveying rollers 2 are arranged;

[0038] It also includes a barrel guide assembly;

[0039] The barrel guide assembly includes a support frame 5 fixedly connected to one side of the frame 1. Two limiting plates 8 and multiple limiting plates 23 are sleeved on the support frame 5, and the limiting plates 23 are located between the two limiting plates 8. The left limiting plate 8 is fixedly connected to the support frame 5, the right limiting plate 8 is slidably connected to the support frame 5, and the limiting plates 23 are slidably connected to the support frame 5.

[0040] Mounting base 21 is fixedly connected to the left limit plate 1 8 and multiple limit plates 23. An ultrasonic liquid level sensor 26 is provided on one side of the bottom of the mounting base 21. A baffle 7 is fixedly connected to the end of the frame 1. A control panel 27 is provided on one side of the frame 1.

[0041] In this embodiment, as Figure 2 , Figures 6-8 As shown, both limit plates 1 and 23 are rotatably equipped with connecting rod 18 on their upper ends, and limit plate 23 is rotatably equipped with connecting rod 29 on its upper end. One end of connecting rod 18 is rotatably connected to one end of connecting rod 29, and the ends of two adjacent connecting rods 29 are rotatably connected.

[0042] A cylinder 6 is fixedly connected to one side of the support frame 5, and the piston end of the cylinder 6 is fixedly connected to one side of the right limit plate 8.

[0043] Mounting base 20 is fixedly connected to the right limit plate 1 8 and multiple limit plates 23. An infrared probe 25 is provided on one side of the bottom of the mounting base 1 20.

[0044] Support blocks 22 are fixedly connected to the left limiting plate 8 and multiple limiting plates 23. A blocking block 16 is rotatably set on one side of the upper end of the support block 22.

[0045] A motor 17 is fixedly connected to one side of the support block 22, and the output end of the motor 17 is fixedly connected to one end of the blocking block 16.

[0046] Specifically, in existing technology, the detection end of the ultrasonic level sensor 26 is aligned with the cutting fluid in the container to measure the cutting fluid level. When it is necessary to measure the cutting fluid level in multiple containers, to improve measurement efficiency, the plastic container containing the cutting fluid is usually placed on the conveying roller 2, which moves it to below the ultrasonic level sensor 26. However, when the conveying roller 2 moves the plastic container, it is prone to deviation due to uneven force, and cannot accurately reach below the ultrasonic level sensor 26 along the preset trajectory, thus affecting normal measurement.

[0047] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0048] This solution is applied to measuring the cutting fluid level in plastic buckets of the same specifications from the same batch. First, the device is operated using control panel 27. Based on the diameter of the plastic bucket, cylinder 6 drives the right-side limiting plate 8 to slide on the support frame 5. With the coordinated action of connecting rods 18 and 19, multiple limiting plates 23 also move synchronously, adjusting the distance between limiting plates 8 and 23. Similarly, the distance between adjacent limiting plates 8 will change until it equals the diameter of the plastic bucket. Thus, multiple conveying channels matching the specifications of the plastic buckets are formed through the coordinated action of limiting plates 8 and 23.

[0049] Multiple plastic buckets are then placed on conveyor roller 2, which moves the buckets. When a bucket reaches limit plate 23, it enters the conveying channel. Since only one bucket can pass through the channel at a time, the initially disordered buckets will be arranged in the channel. Because the detection range of infrared probe 25 and ultrasonic level sensor 26 is within the width of the conveying channel, the buckets will inevitably reach below them. When infrared probe 25 detects a bucket, motor 17 rotates blocking block 16, blocking the bucket. At this time, ultrasonic level sensor 26 activates, allowing measurement of the cutting fluid level in the bucket. After measurement, blocking block 16 resets, and subsequent buckets move below infrared probe 25 and ultrasonic level sensor 26 for measurement again. By repeating this process, the cutting fluid level in multiple buckets can be measured. This allows multiple plastic buckets to move orderly beneath the ultrasonic level sensor 26 under the guidance of the first limiting plate 8 and the second limiting plate 23. This prevents the plastic buckets from shifting due to uneven force during transport, thus avoiding situations where they fail to accurately reach the ultrasonic level sensor 26 along a preset trajectory and thus affect normal measurement. Furthermore, the multi-channel design allows for simultaneous measurement of the cutting fluid level in multiple plastic buckets, improving measurement efficiency.

[0050] The plastic bucket that has completed the measurement will continue to move until it is blocked by baffle 7.

[0051] In this embodiment, as Figures 2-4 As shown, it also includes an anti-jamming deflection component;

[0052] The anti-jamming deflection assembly includes a groove 24 on one side of the limiting plate 23, a push rod 12 slidably passing through the groove 24, a moving rod 15 fixedly connected to one end of the push rod 12, and a friction roller 13 rotatably connected to one end of the moving rod 15.

[0053] A cylinder 11 is fixedly connected to one side of the limiting plate 8, and the piston end of the cylinder 11 is fixedly connected to one end of the push rod 12.

[0054] One end of the moving rod 15 is fixedly connected to a motor 14, and the output end of the motor 14 is fixedly connected to one end of the friction roller 13.

[0055] Specifically, in the above embodiments, although the limiting plate 8 and the limiting plate 23 can be used to guide the plastic bucket, when the plastic bucket comes into contact with the end of the limiting plate 23, the plastic bucket is easily blocked and cannot enter the conveying channel smoothly, thus affecting the subsequent normal measurement work.

[0056] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0057] The friction roller 13 is continuously rotated by the motor 2 14. When the plastic bucket reaches the end of the limit plate 1 8, the plastic bucket will deflect due to contact with the rotating friction roller 13, thus smoothly entering the conveying channel and ensuring the smooth progress of subsequent measurement work.

[0058] Furthermore, in some cases, when two plastic buckets are stuck at the entrance of the conveyor channel with their surfaces touching, the friction between the friction roller 13 and the buckets may not be sufficient to effectively dislodge them. Therefore, to avoid this situation, while the friction roller 13 is rotating, the cylinder 11 can drive the push rod 12 to slide back and forth in the groove 24. This allows the friction roller 13 to push the plastic buckets apart, separating them. The separated buckets can then continue to move under the action of the conveyor roller 2 and smoothly enter the conveyor channel, thus preventing the two buckets from getting stuck at the entrance of the conveyor channel and affecting subsequent measurement work.

[0059] In this embodiment, as Figure 5 As shown, it also includes splash-proof components;

[0060] The splash-proof assembly includes multiple fixed blocks 28 fixedly connected to the frame 1. A lead screw 10 is rotatably mounted on the upper end of one fixed block 28, and slide rods 4 are fixedly connected to the upper ends of the other fixed blocks 28. Multiple slide rods 4 are slidably connected to a cover plate 3. One side of the cover plate 3 is threadedly connected to the lead screw 10. A motor 9 is fixedly connected to the bottom of one fixed block 28, and one end of the lead screw 10 is fixedly connected to the output end of the motor 9.

[0061] Specifically, in the above embodiments, although the jam can be released by actively pushing the plastic bucket, since the conveying direction of the plastic bucket is opposite to the pushing direction, when the plastic bucket is pushed, the cutting fluid inside it will shake due to inertia, which can easily splash out through the bucket opening, thus affecting the accuracy of subsequent measurements.

[0062] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0063] Depending on the height of the plastic bucket, the motor 9 drives the lead screw 10 to rotate, thereby raising and lowering the cover plate 3. This allows the lid plate 3 to cover the opening of the plastic bucket without affecting its transport. When the plastic bucket is pushed, the opening remains covered, effectively preventing the cutting fluid from splashing out and ensuring the accuracy of subsequent measurements.

[0064] Working Principle: First, the device is operated using the control panel 27. Based on the diameter of the plastic bucket, cylinder 6 drives the right-side limiting plate 8 to slide on the support frame 5. With the coordinated action of connecting rods 18 and 19, multiple limiting plates 23 also move synchronously, adjusting the distance between limiting plates 8 and 23. Similarly, the distance between adjacent limiting plates 8 will change until it equals the diameter of the plastic bucket. This creates multiple conveying channels matching the specifications of the plastic buckets. Then, multiple plastic buckets are placed on the conveying roller 2, which moves them. When a bucket reaches the limiting plate 23, it enters the conveying channel. Since only one bucket can pass through at a time, the initially disordered buckets will be arranged neatly within the conveying channel. Since the detection range of the infrared probe 25 and the ultrasonic level sensor 26 is within the width of the conveying channel, the plastic bucket will inevitably reach below them. When the infrared probe 25 detects the plastic bucket, the corresponding motor 17 drives the blocking block 16 to rotate, blocking the plastic bucket. At this time, the ultrasonic level sensor 26 activates, allowing measurement of the cutting fluid level in the plastic bucket. After measurement, the blocking block 16 resets, and subsequent plastic buckets continue to move below the infrared probe 25 and the ultrasonic level sensor 26 for measurement again. By repeating the above operation, the cutting fluid level in multiple plastic buckets can be measured. Under the guidance of the limiting plate 8 and the limiting plate 23, multiple plastic buckets move orderly below the ultrasonic level sensor 26, preventing them from shifting due to uneven force during transport and failing to accurately reach the ultrasonic level sensor 26 along the preset trajectory, thus affecting normal measurement. Furthermore, the multi-channel design allows for simultaneous measurement of the cutting fluid level in multiple plastic buckets, improving measurement efficiency. The plastic bucket that has completed the measurement will continue to move until it is blocked by baffle 7.

[0065] The friction roller 13 is continuously rotated by the motor 2 14. When the plastic bucket reaches the end of the limit plate 1 8, the plastic bucket will deflect due to contact with the rotating friction roller 13, thus smoothly entering the conveying channel and ensuring the smooth progress of subsequent measurement work.

[0066] Furthermore, in some cases, when two plastic buckets are stuck at the entrance of the conveyor channel with their surfaces touching, the friction between the friction roller 13 and the buckets may not be sufficient to effectively dislodge them. Therefore, to avoid this situation, while the friction roller 13 is rotating, the cylinder 11 can drive the push rod 12 to slide back and forth in the groove 24. This allows the friction roller 13 to push the plastic buckets apart, separating them. The separated buckets can then continue to move under the action of the conveyor roller 2 and smoothly enter the conveyor channel, thus preventing the two buckets from getting stuck at the entrance of the conveyor channel and affecting subsequent measurement work.

[0067] Depending on the height of the plastic bucket, the motor 9 drives the lead screw 10 to rotate, thereby raising and lowering the cover plate 3. This allows the lid plate 3 to cover the opening of the plastic bucket without affecting its transport. When the plastic bucket is pushed, the opening remains covered, effectively preventing the cutting fluid from splashing out and ensuring the accuracy of subsequent measurements.
