Description

Technical Field

[0001] The present invention relates to the technical field of paint equipment, and more particularly to a paint stirring device with a viscosity detection function. Background Art

[0002] A paint mixing device for oil-based paints is an auxiliary device used in the production process of oil-based paints to stir its ingredients so that production can be carried out better, and it is widely used in the field of oil-based paint production.

[0003] Chinese Patent No. CN218944979U discloses an automatic paint mixing device for oil-based paints, including a paint mixing device, which includes a box body, a feed pipe, a discharge pipe, a circuit controller, a debugging port, an inspection box, a sealing valve, a Stormer viscometer, a first motor, a stirring blade, a circulation pipe, a water tank, a pump, an installation box, a coupling shaft, a fixing ring, a connecting rod and a scraper. The circuit controller is arranged on one side of the middle end of the side of the box body. A debugging port is opened at the middle end of the side of the box body where the circuit controller is provided. A sealing valve is provided on the front of the inspection box. The top and bottom of the side of the box body where the circuit controller is provided are both fixedly installed with a first motor. In this automatic paint mixing device for oil-based paints, by opening the sealing valve, the paint enters the inspection box through the debugging port, so that the Stormer viscometer can detect the viscosity of the paint. After passing the inspection, the mixed paint is taken out through the discharge pipe to achieve the effect of feedback on viscosity.

[0004] Although the above device can detect the viscosity of the mixed paint through the Stormer viscometer, the existing Stormer viscometer cannot achieve effective automatic cleaning. As a result, when the paint is detected each time, the inspection end of the Stormer viscometer will stick to the paint. To ensure the accuracy of the detection, manual cleaning is required. However, manual cleaning will waste manpower and cannot perform continuous detection, affecting production efficiency. Summary of the Invention

[0016] The beneficial effects of the present invention compared with the prior art are:

[0017] 1. This device solves the problem of manual cleaning required by traditional Stormer viscometers through an automatic cleaning device. After each viscosity measurement is completed, the automatic cleaning device can quickly and effectively clean the test cup, ensuring the cleanliness of the test cup, thus eliminating the need for manual intervention and greatly saving labor costs.

[0018] 2. The identification and detection device in this device, composed of an industrial camera and an infrared sensor, can monitor the falling state of the paint in the test cup in real time and accurately control the sampling device to stop sampling when the paint overflows, thus ensuring the accuracy of the paint sample volume for each detection. In addition, by controlling the flow device to open the bottom of the test cup and cooperating with the design of the diversion receiving pipe and the receiving hopper, the flow of the paint sample can be accurately guided, further improving the stability of the detection.

[0019] 3. This device realizes the efficient and accurate extraction and transportation of paint samples through the coordinated action of a reflux suction pipeline, a suction pump, a three-way valve, and an extraction pipe.

[0033] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments

[0034] See Figures 1 to 11 As shown in Figures 1 to 11 , a paint stirring device with a viscosity detection function includes a viscosity automatic detection device installed on the side of the stirring tank 1. The viscosity automatic detection device includes a fixed installation shell 2, a diversion and material receiving pipe 21, a rotary switching device 3, a horizontal scraping mechanism 4, a test cup 5, a sampling device 7, a control flow device 6, an identification and detection device 9, and an automatic cleaning device 8. The fixed installation shell 2 is installed on the side of the stirring tank 1. The diversion and material receiving pipe 21 is installed at the axial center position of the fixed installation shell 2. A material receiving hopper 22 is installed at the material receiving end of the diversion and material receiving pipe 21, and the discharge end of the diversion and material receiving pipe 21 is connected to the inside of the stirring tank 1. The rotary switching device 3 is installed inside the fixed installation shell 2, and the rotary end of the rotary switching device 3 is coaxially arranged with the diversion and material receiving pipe 21. A plurality of test cups 5 are provided and are evenly distributed at the rotary end of the rotary switching device 3. The horizontal scraping mechanism 4 is arranged above the test cup 5. The sampling device 7 is installed on the stirring tank 1. The input end of the sampling device 7 is connected to the inside of the stirring tank 1, and the output end of the sampling device 7 is arranged directly above the test cup 5. The control flow device 6 is installed on the side of the fixed installation shell 2, and the movable end of the control flow device 6 extends towards the discharge end of the test cup 5. The identification and detection device 9 is installed on the side of the fixed installation shell 2, and the detection end of the identification and detection device 9 is arranged between the test cup 5 and the material receiving hopper 22. The automatic cleaning device 8 is installed at the bottom of the fixed installation shell 2, and the cleaning end of the automatic cleaning device 8 extends upwards.

[0035] Inside the stirring tank 1, the paint materials are fully stirred and mixed by a stirring mechanism to ensure the uniformity of the paint. The sampling device 7 regularly extracts paint samples from the inside of the stirring tank 1, and the samples are precisely conveyed to the test cup 5 through the output end of the sampling device 7. The paint samples are continuously conveyed to the test cup 5 until the test cup 5 is full and overflows. The identification and detection device 9 monitors the falling state of the paint in the test cup 5 in real time. Once paint overflow is detected, the sampling device 7 immediately stops sampling. The horizontal scraping mechanism 4 is activated, and the working end of the horizontal scraping mechanism 4 levels the cup mouth of the test cup 5 to ensure that the paint inside the test cup 5 is parallel to the cup mouth. At this time, the test cup 5 is ready for viscosity detection. The control flow device 6 opens the bottom of the test cup 5, so that the paint inside the test cup 5 flows out from the bottom. The diversion and material receiving pipe 21 cooperates with the material receiving hopper 22 to guide and collect the falling paint, and guides the collected paint into the inside of the stirring tank 1. At the same time, the identification and detection device 9 detects again, identifies and detects the paint flowing out from the bottom of the test cup 5, and records the time when the paint flows out. By the outflow speed of the paint, the viscosity of the paint can be judged.

[0036] After the viscosity detection is completed, the rotation switching device 3 is started to drive the test cup 5 to rotate. The used test cup 5 is moved to directly above the automatic cleaning device 8, while the new test cup 5 is moved to below the sampling device 7 to prepare for the next round of sampling and detection. The automatic cleaning device 8 is started to automatically clean the used test cup 5 to ensure the cleanliness of the test cup 5 and prepare for the next detection.

[0037] Through the cycle of the above steps, this device realizes the continuous detection of paint viscosity. The automated cleaning and switching mechanism greatly reduces manual intervention, improves the detection efficiency, and saves labor costs at the same time.

[0038] The identification and detection device 9 is composed of an industrial camera and an infrared sensor, and is used to detect the falling state of the paint in the test cup 5 in real time.

[0039] See Figures 3 to 7 As shown, the rotation switching device 3 includes a rotation mounting frame 32 rotatably mounted inside the fixed mounting shell 2. A plurality of positioning holes are provided on the side of the rotation mounting frame 32. A plurality of inner wall scraping mechanisms 33 are mounted on the rotation mounting frame 32. A rotation positioning device 34 is mounted beside the rotation mounting frame 32. The rotation switching device 3 further includes a first rotation driving device 31 that drives the rotation mounting frame 32 to rotate.

[0040] The first rotation driving device 31 is a prior art and will not be elaborated here.

[0041] The working end of the rotation positioning device 34 is used to limit and insert into the positioning hole to stably limit the rotation mounting frame 32 and ensure the stability of the rotation adjustment.

[0042] Before the device is started, the rotation mounting frame 32 is in the initial position, and the test cup 5 is aligned with the output end of the sampling device 7 to prepare to receive the paint sample. At this time, the working end of the rotation positioning device 34 is inserted into a positioning hole of the rotation mounting frame 32 to ensure the stability of the rotation mounting frame 32.

[0043] When the sampling device 7 regularly extracts the paint sample from the inside of the mixing tank 1 and transports it to the test cup 5, the identification and detection device 9 monitors the falling state of the paint in the test cup 5 in real time. Once paint overflow is detected, the sampling device 7 immediately stops sampling. Subsequently, the horizontal scraping mechanism 4 is started to scrape the cup mouth of the test cup 5 to ensure that the paint inside the test cup 5 is parallel to the cup mouth. At this time, the test cup 5 is ready for viscosity detection. The control flow device 6 opens the bottom of the test cup 5 to allow the paint inside the test cup 5 to flow out from the bottom. The identification and detection device 9 detects again, records the time when the paint flows out, and judges the viscosity of the paint based on the flow rate of the paint.

[0044] After the viscosity detection is completed, the first rotation driving device 31 is started to drive the rotating mounting frame 32 to rotate. During the rotation, the working end of the rotation positioning device 34 is withdrawn from the current positioning hole, and as the rotating mounting frame 32 rotates, the working end of the rotation positioning device 34 will penetrate into the next positioning hole, realizing stable limit for the rotating mounting frame 32. When the rotating mounting frame 32 rotates to the specified position, the used test cup 5 is moved to directly above the automatic cleaning device 8, while the new test cup 5 is moved to below the sampling device 7, preparing for the next round of sampling and detection. The automatic cleaning device 8 is started to automatically clean the used test cup 5. At the same time, the inner wall scraping mechanism 33 drives the inner wall of the fixed mounting shell 2 to be scraped and cleaned under the drive of the rotating mounting frame 32, ensuring the cleanliness of the fixed mounting shell 2.

[0045] Through the cycle of the above steps, continuous detection and automatic cleaning of the paint viscosity are realized. The automated cleaning and switching mechanism greatly reduces manual intervention, improves the detection efficiency, and saves labor costs at the same time.

[0046] See Figure 4 and Figure 5 As shown, the inner wall scraping mechanism 33 includes a fixed mounting strip 331 installed on the side of the rotating mounting frame 32. A contact scraping head 332 is provided above the fixed mounting strip 331. A guide post is installed at the bottom of the contact scraping head 332. The guide post is slidably connected to the fixed mounting strip 331. A first pressing spring 333 is installed between the fixed mounting strip 331 and the contact scraping head 332. The top of the contact scraping head 332 abuts against the inner wall of the fixed mounting shell 2.

[0047] When the test cup 5 rotates, some residual paint may fall onto the inner wall of the fixed mounting shell 2. At this time, under the pushing force of the first pressing spring 333, the top of the contact scraping head 332 will always be in close contact with the inner wall of the fixed mounting shell 2.

[0048] When the rotating mounting frame 32 rotates under the drive of the first rotation driving device 31, the contact scraping head 332 will perform scraping movement along the inner wall of the fixed mounting shell 2. Since the shape of the contact scraping head 332 matches the inner wall of the fixed mounting shell 2, it can effectively scrape and clean the residual paint on the inner wall of the fixed mounting shell 2. Through the coordinated work of the fixed mounting strip 331, the contact scraping head 332, the guide post and the first pressing spring 333, automatic scraping and cleaning of the inner wall of the fixed mounting shell 2 is realized.

[0049] See Figure 4 and Figure 7As shown in the figure, the rotation positioning device 34 includes a first linear driver 341 installed on the fixed mounting shell 2. An insertion positioning sleeve 342 is installed on the output end of the first linear driver 341. The insertion positioning sleeve 342 is slidably connected to the first linear driver 341, and a second compression spring 343 is installed between the insertion positioning sleeve 342 and the fixed mounting shell 2.

[0050] Before the device starts, the rotating mounting frame 32 is in the initial position. The test cup 5 is aligned with the output end of the sampling device 7 and is ready to receive the paint sample. At this time, the output end of the first linear driver 341 is in the extended state. Under the action of the second compression spring 343, the insertion positioning sleeve 342 is tightly inserted into a positioning hole of the rotating mounting frame 32 to achieve stable positioning of the rotating mounting frame 32.

[0051] When viscosity detection switching is required, the first rotation driving device 31 starts to drive the rotating mounting frame 32 to rotate. During the rotation process, the output end of the first linear driver 341 gradually contracts, driving the insertion positioning sleeve 342 to be withdrawn from the current positioning hole, and then the first linear driver 341 resets. Due to the elastic action of the second compression spring 343, the insertion positioning sleeve 342 can maintain close contact with the rotating mounting frame 32. When the rotating mounting frame 32 rotates to the specified position, the insertion positioning sleeve 342 is tightly inserted into the next positioning hole under the action of the second compression spring 343 to achieve stable positioning of the rotating mounting frame 32. This effectively ensures the stability of the rotation switching.

[0052] See Figures 4 to 6 As shown in the figure, the horizontal scraping mechanism 4 includes a second linear driver 41 installed on the side of the fixed mounting shell 2. A horizontal scraping strip 42 is installed on the output end of the second linear driver 41. The bottom of the horizontal scraping strip 42 is parallel to the top of the test cup 5. An inclined scraping surface 43 is provided on the side of the horizontal scraping strip 42. The horizontal scraping mechanism 4 further includes a scraping surface cleaning mechanism installed inside the fixed mounting shell 2. The scraping surface cleaning mechanism includes an inclined scraper 44 installed inside the fixed mounting shell 2 in an inclined manner. The inclined scraper 44 is slidably connected to the fixed mounting shell 2, and a third compression spring 45 is installed between the inclined scraper 44 and the fixed mounting shell 2.

[0053] When the sampling device 7 transports the paint sample to the test cup 5 and spills, the recognition and detection device 9 will immediately recognize this state and stop sampling. At this time, the second linear driver 41 starts to push the horizontal scraping strip 42 to move horizontally. The horizontal scraping strip 42 slides over the top of the test cup 5 to scrape the paint in the test cup 5 in parallel, ensuring that the amount of paint inside the test cup 5 is parallel to the cup mouth, thus ensuring the accuracy of the test.

[0054] After the horizontal scraper 42 completes the scraping task, the second linear drive 41 continues to push the horizontal scraper 42 to move toward the inclined scraper 44. The inclined scraping surface 43 on the side of the horizontal scraper 42 conflicts with the inclined scraper 44. The inclined scraper 44 is installed obliquely inside the fixed installation shell 2 and is slidably connected with the fixed installation shell 2. When the inclined scraper 44 is guided by the inclined scraper 43, the inclined scraper 44 will slide along the inside of the fixed installation shell 2 and shrink and move. In this process, the inclined scraper 44 will effectively scrape and clean the inclined scraping surface 43 and the bottom of the horizontal scraper 42, and remove the paint residue attached to the horizontal scraper 42. In addition, in order to enhance the cleaning effect of the inclined scraper 44, a third push spring 45 is also installed between the inclined scraper 44 and the fixed installation shell 2. The third push spring 45 provides a continuous thrust for the inclined scraper 44, so that it can contact the horizontal scraper 42 more closely, thereby improving the cleaning effect. The horizontal scraping mechanism 4 ensures the accuracy of the amount of paint in the test cup 5.

[0055] See also Figure 4 and Figure 9 As shown, a first liquid outlet 51 is provided at the bottom of the test cup 5 , an overflow groove 52 is provided at the outer ring of the test cup 5 , a second liquid outlet 521 is provided at the bottom of the overflow groove 52 , and a closing control head 53 is installed on the first liquid outlet 51 .

[0056] The closing control head 53 is used to cooperate with the flow control device 6 to control the liquid outflow state of the first liquid outlet 51 .

[0057] During the paint filling stage, the flow control device 6 cooperates with the closing control head 53 to ensure that the first liquid outlet 51 is effectively blocked. At this time, the sampling device 7 draws paint from the mixing tank 1 and accurately delivers the paint sample to the inside of the test cup 5. With the continuous input of the paint sample, the paint liquid level in the test cup 5 gradually rises until the paint overflows into the overflow groove 52 set on the outer ring of the test cup 5. The overflow groove 52 is designed to provide a buffer area. When the paint flows out from the second liquid outlet 521 at the bottom of the overflow groove 52, the identification and detection device 9 can quickly capture this signal and immediately notify the sampling device 7 to stop sampling, thereby avoiding waste and pollution of paint.

[0058] After the paint is filled, the test cup 5 is ready for viscosity testing. At this time, the control flow device 6 is reset and disengaged from the closed control head 53, and the closed control head 53 without restriction immediately opens the first liquid outlet 51 of the test cup 5. Under the action of gravity, the paint sample inside the test cup 5 begins to flow out of the first liquid outlet 51. The identification and detection device 9 is started again to monitor the paint flowing out from the bottom of the test cup 5 in real time and record the time when the paint flows out. The viscosity characteristics of the paint can be indirectly judged by the outflow speed of the paint.

[0059] See also Figures 2 to 9As shown in the figure, the closing control head 53 includes an annular regulation track 531 installed on the first liquid outlet hole 51. The annular regulation track 531 is communicated with the first liquid outlet hole 51. A regulation turntable 532 is installed inside the annular regulation track 531. An arc-shaped installation groove 5322 is provided on the regulation turntable 532. A return spring 533 is installed inside the arc-shaped installation groove 5322. One end of the return spring 533 abuts against the regulation turntable 532, and the end of the return spring 533 away from the regulation turntable 532 abuts against the annular regulation track 531. A rotating handle 5321 is provided on the side of the regulation turntable 532.

[0060] The rotation adjustment of the regulation turntable 532 can block the first liquid outlet hole 51, and the rotating handle 5321 on the side of the regulation turntable 532 is convenient for rotation adjustment.

[0061] In the paint filling stage, first, when the control flow device 6 pushes the rotating handle 5321 on the side of the regulation turntable 532, the regulation turntable 532 will rotate to the specified position accordingly. At this time, some structures on the regulation turntable 532 will accurately block the first liquid outlet hole 51 to ensure that the paint will not leak from the test cup 5 during the filling process. At the same time, the sampling device 7 sucks the paint from the mixing tank 1 and accurately transports the paint sample into the test cup 5. As the paint sample continues to be input, the paint liquid level in the test cup 5 gradually rises until the paint overflows into the overflow tank 52 arranged outside the test cup 5. When the paint flows out from the second liquid outlet hole 521 at the bottom of the overflow tank 52, the identification and detection device 9 can quickly capture this signal and immediately notify the sampling device 7 to stop sampling, thus effectively avoiding the waste and pollution of the paint.

[0062] After the paint filling is completed, the test cup 5 is ready for viscosity detection. At this time, the control flow device 6 resets and no longer applies a thrust to the rotating handle 5321 of the regulation turntable 532. Under the action of the return spring 533, the regulation turntable 532 will automatically reset and stop blocking the first liquid outlet hole 51. Subsequently, the paint sample inside the test cup 5 begins to flow out from the first liquid outlet hole 51 under the action of gravity. The identification and detection device 9 is started again to monitor the paint flowing out from the bottom of the test cup 5 in real time and record the time when the paint flows out. Through the flow rate of the paint, the viscosity characteristics of the paint can be indirectly judged, thus completing the entire viscosity detection process.

[0063] See Figure 1 and Figure 10 As shown in the figure, the control flow device 6 includes a third linear driver 61 installed on the side of the fixed installation shell 2. A push plate 62 is installed at the output end of the third linear driver 61.

[0064] During the paint filling stage, the third linear actuator 61 is activated to drive the push plate 62 to move forward and backward telescopically. Since the contact surface of the push plate 62 has a certain flexibility, it can effectively adapt to and conform to the shape of the rotating handle 5321 of the regulation turntable 532, thus ensuring that the rotating handle 5321 can be stably and accurately pushed during the pushing process. When the push plate 62 contacts the rotating handle 5321 of the regulation turntable 532, it will continue to move forward and apply a thrust to the rotating handle 5321, causing the regulation turntable 532 to rotate to the designated position. At this position, some structures on the regulation turntable 532 will precisely block the first liquid outlet hole 51, thereby ensuring that the paint does not leak from the test cup 5 during the filling process.

[0065] See Figures 1 to 7 As shown, the sampling device 7 includes a reflux suction pipeline 71 installed on the mixing tank 1. Both the input end and the output end of the reflux suction pipeline 71 are connected to the mixing tank. A suction pump 72 and a three-way valve 73 are installed on the reflux suction pipeline 71. An extraction pipe 731 is also installed on the three-way valve 73. The extraction pipe 731 is arranged directly above the test cup 5. The sampling device 7 further includes a temperature detector 74 installed on the fixed mounting shell 2. The temperature detector 74 is arranged above the test cup 5.

[0066] During the paint filling stage, the suction pump 72 is first activated. By generating negative pressure, the suction pump 72 makes the input end of the reflux suction pipeline 71 have a strong suction force. In this way, the paint in the mixing tank 1 is sucked into the reflux suction pipeline 71 and starts to flow in the reflux suction pipeline 71. The purpose of this step is to remove the residual paint remaining in the reflux suction pipeline 71 and ensure the purity of the subsequent extracted paint samples.

[0067] After the paint circulates in the reflux suction pipeline 71 for a period of time, the three-way valve 73 starts to function. The three-way valve 73 switches the flow direction, causing the paint that originally flowed towards the mixing tank 1 to be redirected to the extraction pipe 731. At this time, the extraction pipe 731 is located directly above the test cup 5, and the extraction pipe 731 is responsible for precisely delivering the paint sample into the test cup 5. In this way, the paint sample is successfully extracted and placed in the test cup 5, ready for subsequent viscosity detection.

[0068] While the paint sample is being extracted, the temperature detector 74 is also playing an important role. The temperature detector 74 is arranged above the test cup 5 and can detect the temperature of the extracted paint in real time.

[0069] The sampling device 7 realizes the precise extraction and delivery of the paint sample. At the same time, the real-time detection function of the temperature detector 74 also provides a strong guarantee for the accuracy of the viscosity detection.

[0070] See Figure 2 、 Figure 4 andFigure 11 As shown, the automatic cleaning device 8 includes a material receiving base 81 installed at the bottom of the fixed installation shell 2. A drain pipe 811 is provided on the side of the material receiving base 81. A limiting guide sleeve 82 is rotatably installed at the bottom of the material receiving base 81. The limiting guide sleeve 82 is driven by a second rotation driving device 83. An extendable and movable telescopic installation pipe 84 is installed inside the limiting guide sleeve 82. The telescopic installation pipe 84 is connected to the infusion pipeline. A plurality of drain holes are provided at the top of the telescopic installation pipe 84. A cleaning sponge sleeve 85 is also sleeved on the top of the telescopic installation pipe 84. The cleaning sponge sleeve 85 is detachably connected to the telescopic installation pipe 84. A fourth linear driver 86 is also installed on the side of the material receiving base 81. A connecting collar 87 is installed at the output end of the fourth linear driver 86. One end of the connecting collar 87 away from the fourth linear driver 86 is connected to the telescopic installation pipe 84.

[0071] The infusion pipeline is used to connect the cleaning liquid conveying device, and the cleaning liquid conveying device can stably convey the cleaning liquid to the telescopic installation pipe 84 through the infusion pipeline. The second rotation driving device 83 is a prior art and will not be elaborated here.

[0072] First, the infusion pipeline is connected to the cleaning liquid conveying device to ensure that the cleaning liquid can be stably conveyed into the telescopic installation pipe 84. A plurality of drain holes are provided at the top of the telescopic installation pipe 84 for evenly spraying the cleaning liquid onto the cleaning sponge sleeve 85.

[0073] During the cleaning process, the fourth linear driver 86 is started. The output end of the fourth linear driver 86 is connected to the telescopic installation pipe 84 through the connecting collar 87, driving the telescopic installation pipe 84 to telescopically move in the limiting guide sleeve 82. When the telescopic installation pipe 84 rises, it will drive the cleaning sponge sleeve 85 to be inserted into the inside of the test cup 5 together. The shape of the cleaning sponge sleeve 85 is the same as that of the test cup 5 to ensure that it can closely fit the inner wall of the test cup 5 to achieve a better cleaning effect.

[0074] Subsequently, the second rotation driving device 83 is started to drive the limiting guide sleeve 82 to rotate. Since the limiting guide sleeve 82 is connected to the telescopic installation pipe 84, the telescopic installation pipe 84 will also rotate synchronously. During the rotation, the cleaning sponge sleeve 85 rotates accordingly, and the cleaning liquid will penetrate from the drain holes of the telescopic installation pipe 84 onto the cleaning sponge sleeve 85. In this way, the cleaning sponge sleeve 85 can effectively clean the inner wall of the test cup 5 when rotating. After the cleaning is completed, the fourth linear driver 86 is started again to drive the telescopic installation pipe 84 to descend, taking the cleaning sponge sleeve 85 out of the test cup 5. At this time, the cleaning liquid and the remaining stains will flow out of the device through the drain pipe 811.

[0075] The entire cleaning process has a high degree of automation and does not require manual intervention, greatly improving the cleaning efficiency and accuracy. At the same time, the detachable design of the cleaning sponge cover 85 also facilitates replacement and maintenance after cleaning, ensuring the long-term stable operation of the cleaning device.

[0076] Specific working principle:

[0077] Inside the mixing tank 1, the paint material is fully stirred and mixed by the stirring mechanism to ensure the uniformity of the paint. The sampling device 7 regularly extracts paint samples from inside the mixing tank 1, and the samples are precisely conveyed to the test cup 5 through the output end of the sampling device 7. The paint samples are continuously conveyed to the test cup 5 until the test cup 5 is full and overflows. The identification and detection device 9 continuously monitors the falling state of the paint in the test cup 5. Once paint overflow is detected, the sampling device 7 immediately stops sampling. The horizontal scraping mechanism 4 is activated, and the working end of the horizontal scraping mechanism 4 levels the mouth of the test cup 5 to ensure that the paint inside the test cup 5 is parallel to the cup mouth. At this time, the test cup 5 is ready for viscosity detection. The control flow device 6 opens the bottom of the test cup 5, allowing the paint inside the test cup 5 to flow out from the bottom. The diversion and receiving pipe 21 and the receiving hopper 22 cooperate to guide and collect the falling paint and guide the collected paint back into the mixing tank 1. At the same time, the identification and detection device 9 detects again, identifies and detects the paint flowing out from the bottom of the test cup 5, and records the time when the paint flows out. Based on the paint outflow speed, the viscosity of the paint can be judged.

[0078] After the viscosity detection is completed, the rotation and switching device 3 is activated to drive the test cup 5 to rotate. The used test cup 5 is moved directly above the automatic cleaning device 8, while the new test cup 5 is moved below the sampling device 7 to prepare for the next round of sampling and detection. The automatic cleaning device 8 is activated to automatically clean the used test cup 5 to ensure the cleanliness of the test cup 5 and prepare for the next detection.

[0079] Through the cycle of the above steps, this device realizes the continuous detection of paint viscosity. The automated cleaning and switching mechanisms greatly reduce manual intervention, improve the detection efficiency, and save labor costs at the same time.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
