Description

Technical Field

[0001] This invention relates to the technical field of rubber products, and in particular to an online automatic sampling and testing device for final rubber compound. Background Technology

[0002] In the tire and rubber products industry, the quality of the final compound (also known as the mixed rubber) directly determines the performance of the final product. During production, frequent sampling of the final compound is necessary to test key indicators such as Mooney viscosity and dispersibility, allowing for real-time monitoring and adjustment of process parameters to ensure stable product quality. Traditional sampling methods rely on manual labor, resulting in low efficiency, inconsistent sampling standards, and delays of several hours or even longer between sampling and obtaining test results, failing to achieve immediate feedback and closed-loop control of the production process.

[0003] To improve the level of automation in sampling, some online sampling devices have emerged in the existing technology. For example, Chinese patent CN111238858B discloses an online sampling device for adhesives. This device achieves automated sampling and marking through a conveying component, a cutting component, a receiving component, and a coding component. Its cutting component uses a ring blade and is equipped with an independent heating component to preheat the cutting edge of the ring blade in order to improve cutting efficiency and reduce blade sticking.

[0004] This existing technology has a significant, inherent drawback when applied to sampling temperature-sensitive final rubber compounds: heating the rubber compound during cutting inevitably alters the local physical properties of the sample. The Mooney viscosity and vulcanization characteristics of the final rubber compound are extremely sensitive to temperature. The thermal effect caused by heating during cutting may lead to premature scorching (early vulcanization) or changes in the molecular chains, making the sample data obtained from subsequent laboratory testing unable to accurately reflect the real-time state of the rubber compound on the production line. This defeats the fundamental purpose of online sampling for guiding process adjustments. Furthermore, the ring cutter in this device must simultaneously complete the cutting and horizontal transfer of the sample to the receiving position, resulting in a complex movement trajectory that affects the sampling cycle time and positioning accuracy. The sample's posture and position after transfer are also not stabilized, directly impacting the accuracy of subsequent coding and detection.

[0005] Therefore, the industry urgently needs an online automated device that can achieve room temperature (cold state), non-destructive, and efficient sampling, and ensure the stability of the sample posture and accurate data traceability throughout the entire process from cutting to testing. This would overcome the defects caused by thermal cutting and process instability in existing technologies and truly achieve real-time and accurate monitoring of product quality. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an online automatic sampling and testing device for final rubber compound.

[0007] The present invention provides an online automatic sampling and testing device for final rubber compound, comprising a first support frame, a feeding conveying assembly, and a controller. The feeding conveying assembly is mounted on the first support frame and is electrically connected to the controller. The device also includes: Auxiliary conveying assembly, which is installed on the first support frame, is used for auxiliary conveying of the final compound rubber; A rubber cutting assembly, which is installed on the auxiliary conveying assembly, is used to cut and sample the final rubber compound; The unloading assembly, which is mounted on the cutting assembly, separates the sample to be cut from the cutting assembly; The receiving assembly, installed at the bottom of the auxiliary conveying assembly, is used to convey the sample; The feeding assembly, which is mounted on the auxiliary conveying assembly, guides the sample from the cutting assembly to the receiving assembly. The inkjet printing component, which is installed on the receiving component, is used to mark the sample with inkjet printing. The detection component, installed on the receiving component, is used for online appearance inspection of samples. During operation, the controller controls the feeding conveyor to transport the final compound, and the auxiliary conveyor assists in its transport. When the cutting component needs to cut and sample the final compound, both the feeding and auxiliary conveyors stop. This allows the cutting component to sample the final compound while the unloading component separates the sample from the cutting component and, with the assistance of the guiding component, transports it to the receiving component. During sample transport by the receiving component, the coding component marks the sample with inkjet printing, and the detection component performs a preliminary appearance inspection on the marked sample. The inspection results are displayed on the screen on the controller, improving detection efficiency and accuracy.

[0008] Preferably, the auxiliary conveying assembly includes a second support frame, electric rollers, and anti-slip strips. The second support frame is installed at the rear end of the first support frame. Multiple sets of electric rollers are rotatably arranged inside the second support frame. Multiple sets of anti-slip strips are evenly spaced on the outer wall of each set of electric rollers. All sets of electric rollers are electrically connected to the controller. In use, the multiple sets of electric rollers rotate synchronously with the feeding conveying assembly, so that the multiple sets of electric rollers and the feeding conveying assembly are seamlessly connected and cooperate to convey the final compound. When it is necessary to sample the final compound on the electric rollers, the feeding conveying assembly and the multiple sets of electric rollers stop rotating. Then, the rubber cutting assembly is operated to cut and sample the final compound on the electric rollers, thereby improving sampling efficiency.

[0009] Preferably, the rubber cutting assembly includes columns, a top plate, an electric push rod, a lifting seat, a guide bar, a disc spring, a knife holder, a ring cutter, and an ultrasonic generator. Two sets of columns are mounted on the top of the electric roller, each set connected to the bottom of the top plate. An electric push rod is mounted on the top of the top plate, with its bottom moving end extending below the top plate and connecting to the top of the lifting seat. A guide bar is mounted on the top of the lifting seat, passing through the top plate and slidably connected to it. A disc spring is mounted at the bottom of the lifting seat, with a knife holder at its bottom and a ring cutter at its bottom. An ultrasonic transducer is located inside the knife holder, and an ultrasonic generator is mounted at the bottom of the lifting seat. The output of the ultrasonic generator is connected to the ultrasonic transducer via a wire. Both the electric push rod and the ultrasonic generator are electrically connected to the controller. For the final refining... When the adhesive is sampled, the controller activates the ultrasonic generator, causing the ultrasonic transducer to drive the blade holder to vibrate. Since the annular cutter is fixedly mounted on the blade holder, the blade holder and the annular cutter undergo synchronous, rapid, micron-level high-frequency vibration. Simultaneously, as the ultrasonic transducer drives the blade holder and the annular cutter to vibrate, the disc spring absorbs and attenuates most of the vibration energy, preventing these vibrations from being directly transmitted to the electric push rod, thus achieving vibration isolation. The controller operates the electric push rod to extend, and the lifting seat, guided by the optical bar, moves the blade holder and the annular cutter downwards. The annular cutter, vibrating at a micron-level high frequency, rapidly cuts the final compound adhesive. When the annular cutter pierces the final compound adhesive, the sample is ejected inside the annular cutter through the unloading assembly, achieving separation of the sample from the annular cutter and improving cutting efficiency. At the same time, the annular cutter cuts the final compound adhesive at room temperature, minimizing changes to the physical properties of the sample.

[0010] Preferably, the unloading assembly includes a telescopic rod, a spring, and a push plate. The telescopic rod and the spring are both located inside the annular cutter. The spring is fitted onto the outside of the telescopic rod. The bottom ends of both the telescopic rod and the spring are connected to the top end of the push plate. The bottom end of the push plate is flush with the bottom end of the annular cutter. Under normal conditions, the bottom end of the push plate is flush with the bottom end of the annular cutter. When the annular cutter vibrates at high frequency to cut the final rubber compound, the final rubber sample enters the annular cutter. Simultaneously, the telescopic rod and the spring shorten, and the push plate rises inside the annular cutter. After the vibrating annular cutter has finished cutting the final rubber sample, the annular cutter drives the final rubber sample to vibrate synchronously at high frequency. Under the high-frequency micro-vibration of the annular cutter, the final rubber sample is in a pre-loosened state. Subsequently, under the action of the spring force, the push plate smoothly pushes the final rubber sample out from the inside of the annular cutter, thus achieving efficient and non-adhesive unloading.

[0011] Preferably, the receiving assembly includes a third support frame, a motor, conveyor rollers, auxiliary rollers, and a conveyor belt. The third support frame is located at the bottom of the second support frame. The motor is mounted on the third support frame. Two sets of conveyor rollers and multiple sets of auxiliary rollers are rotatably mounted inside the third support frame. The conveyor belt is fitted around the outer side of the two sets of conveyor rollers. The output end of the motor is connected to one end of one set of conveyor rollers. The motor is electrically connected to the controller. The controller starts the motor, thereby causing the two sets of conveyor rollers to drive the conveyor belt to rotate in cooperation with the multiple sets of auxiliary rollers. The rotating conveyor belt transports the final rubber sample, enabling inkjet marking and appearance inspection of the sample, reducing intermediate connection links.

[0012] Preferably, the guiding assembly includes a support plate, a conical sleeve, and a rubber ring. The support plate is located inside the second support frame, between two sets of electric rollers. The conical sleeve passes through the support plate and is fixedly connected to it. The top diameter of the conical sleeve is larger than its bottom diameter, and the top diameter is larger than the diameter of the annular cutter. The conical sleeve is directly below the annular cutter. A rubber ring is located at the top of the conical sleeve, and the top of the rubber ring is lower than the top of the electric rollers. In use, the distance between the bottom of the conical sleeve and the conveyor belt is slightly greater than the thickness of the final rubber sample. The rubber ring supports the bottom of the final rubber sample under the support of the conical sleeve, allowing the high-frequency, low-amplitude vibrating annular cutter to cut the final rubber sample. As the annular cutter penetrates the final rubber sample, the sample is pushed out by the push plate inside the annular cutter. The sample is guided inside the conical sleeve, ensuring it is conveyed horizontally by the conveyor belt, preparing for subsequent coding and appearance inspection.

[0013] Preferably, the coding assembly includes a fixed frame, a photoelectric sensor, and a coding machine. The fixed frame is mounted on the third support frame, and the photoelectric sensor and the coding machine are respectively mounted on the fixed frame. Both the photoelectric sensor and the coding machine are electrically connected to the controller. When the conveyor belt moves the final rubber sample to the inside of the fixed frame, the photoelectric sensor detects the final rubber sample and sends a detection signal to the controller. The controller operates the coding machine to mark the final rubber sample using the detection signal, thereby achieving traceability.

[0014] Preferably, the testing assembly includes a testing box, an observation window, and a support. The testing box is fixedly mounted on the third support frame via the support. An image acquisition device is installed inside the testing box, and an observation port is provided on the testing box. A support is provided on the observation port, and the image acquisition device is electrically connected to the controller. The final rubber sample after inkjet marking is conveyed into the testing box by the conveyor belt. The image acquisition device acquires and compares the appearance images of the final rubber sample. The comparison results are displayed and recorded on the display screen on the controller, improving testing efficiency.

[0015] Preferably, it also includes a reinforcing plate, and a reinforcing plate is provided between the column and the top plate; the column and the top plate are strengthened by the reinforcing plate to improve the connection strength.

[0016] Preferably, the image acquisition device is an industrial camera.

[0017] The beneficial effects of this invention are as follows: In use, the feeding and conveying assembly is controlled by the controller to convey the final compound, and the auxiliary conveying assembly assists in conveying the final compound. When the cutting assembly needs to cut and sample the final compound, the feeding and conveying assembly and the auxiliary conveying assembly stop conveying. This allows the cutting assembly to sample the final compound while the unloading assembly separates the sample from the cutting assembly and, with the cooperation of the guiding assembly, conveys it to the receiving assembly. During the sample conveying process by the receiving assembly, the coding assembly marks the sample with coding, and the detection assembly performs a preliminary appearance inspection on the marked sample. The detection results are displayed on the screen on the controller, improving detection efficiency and accuracy. Attached Figure Description

An electric push rod 303 is mounted on the top of the top plate 302, and the bottom moving end of the electric push rod 303 extends below the top plate 302 and connects to the top of the lifting seat 304. A guide bar 305 is mounted on the top of the lifting seat 304. The light bar 305 passes through the top plate 302 and is slidably connected to the top plate 302.

The unloading assembly includes a telescopic rod 401, a spring 402, and a push plate 403. The telescopic rod 401 and the spring 402 are both disposed inside the annular cutter 308. The spring 402 is fitted on the outside of the telescopic rod 401. The bottom ends of the telescopic rod 401 and the spring 402 are connected to the top end of the push plate 403. The bottom end of the push plate 403 is flush with the bottom end of the annular cutter 308.

[0022] In this embodiment, when sampling the final rubber compound, the controller 103 activates the ultrasonic generator 309, causing the ultrasonic transducer to drive the blade holder 307 to vibrate. Since the annular cutter 308 is fixedly mounted on the blade holder 307, the blade holder 307 and the annular cutter 308 undergo synchronous, rapid, micron-level high-frequency vibration. Simultaneously, as the ultrasonic transducer drives the blade holder 307 and the annular cutter 308 to vibrate, the disc spring 306 absorbs and attenuates most of the vibration energy, preventing these vibrations from being directly transmitted to the electric push rod 303, thus achieving vibration isolation. The controller 103 then operates the electric push rod 303 to extend, and the lifting seat 304, guided by the optical rod 305, moves the blade holder 307 and the annular cutter 308 downwards, performing micron-level high-frequency vibration. The vibrating annular cutter 308 rapidly cuts the final rubber compound sample. After the annular cutter 308 has finished cutting the final rubber compound sample, it drives the sample to vibrate synchronously at high frequency. Under the high-frequency micro-amplitude vibration of the annular cutter 308, the sample is in a pre-loose state. Then, the push plate 403, under the action of the spring 402, smoothly pushes the sample out from the inside of the annular cutter 308, thus achieving efficient and non-adhesive unloading. The controller 103 starts the motor 502, which causes the two sets of conveyor rollers 503 to drive the conveyor belt 505 to rotate with the cooperation of multiple sets of auxiliary rollers 504. The rotating conveyor belt 505 transports the final rubber compound sample, enabling the sample to be marked with inkjet printing and inspected for appearance.

[0024] In this embodiment, when sampling the final rubber compound, the controller 103 activates the ultrasonic generator 309, causing the ultrasonic transducer to drive the blade holder 307 to vibrate. Since the annular cutter 308 is fixedly mounted on the blade holder 307, the blade holder 307 and the annular cutter 308 undergo synchronous, rapid, micron-level high-frequency vibration. Simultaneously, as the ultrasonic transducer drives the blade holder 307 and the annular cutter 308 to vibrate, the disc spring 306 absorbs and attenuates most of the vibration energy, preventing these vibrations from being directly transmitted to the electric push rod 303, thus achieving vibration isolation. The controller 103 then operates... The electric push rod 303 extends, and the lifting seat 304, guided by the optical rod 305, drives the knife holder 307 and the annular cutter 308 to move downwards. The annular cutter 308, which performs micron-level high-frequency vibration, rapidly cuts the final rubber compound. After the vibrating annular cutter 308 has finished cutting the final rubber compound sample, the annular cutter 308 drives the final rubber compound sample to perform synchronous high-frequency vibration. Under the action of the high-frequency micro-amplitude vibration of the annular cutter 308, the final rubber compound sample is in a pre-loosened state. Then, under the action of the spring force of the spring 402, the push plate 403 pushes the final rubber compound sample from the annular cutter 307. The material is smoothly ejected from the inner side of the 08, achieving efficient and non-adhesive unloading. The motor 502 is started by the controller 103, causing the two sets of conveyor rollers 503, in conjunction with multiple sets of auxiliary rollers 504, to drive the conveyor belt 505 to rotate. When the final rubber sample is ejected from the inner side of the annular cutter 308 by the push plate 403, the final rubber sample is guided inside the conical sleeve 602, thus transferring the final rubber sample horizontally to the conveyor belt 505 for transport. The rotating conveyor belt 505 transports the final rubber sample, enabling inkjet marking and appearance inspection of the sample. When the final rubber sample is moved to the inside of the fixed frame 701, the photoelectric sensor 702 detects the final rubber sample and sends a detection signal to the controller 103. The controller 103 operates the inkjet printer 703 to mark the final rubber sample with inkjet printing through the detection signal, so as to realize traceability. After the final rubber sample is marked with inkjet printing, it enters the detection box 801 under the conveyor belt 505. The image acquisition device acquires and compares the appearance image of the final rubber sample. The comparison result is displayed and recorded on the display screen on the controller 103, which improves the detection efficiency.

[0025] The main functions achieved by this invention are: 1. Ultrasonic high-frequency vibration cutting is employed. The cutting energy mainly comes from the fatigue breakage of the rubber molecular chains caused by mechanical vibration, rather than thermal melting. The heat generated by the vibration of the annular cutter is an instantaneous and localized byproduct, with minimal thermal impact on the rubber sample, achieving true "cold sampling" and ensuring the originality of the sample and the authenticity of the test data. This is the most fundamental and important creative leap.

[0026] 2. The annular cutter performs only vertical reciprocating motion, focusing on efficient cutting. Sample transfer is handled by a separate lateral transfer mechanism. This "functional separation" design makes the movement of each unit more focused, faster, and more precise, improving the overall reliability and efficiency of the system.

[0027] 3. Conical guide sleeve: During cutting: it rises and tightens the tape, serving as a rigid support platform to ensure a neat cut surface; After cutting: it receives the sample, achieving "zero displacement" in-situ drop reception, simplifying the process; During sample guiding: it guides the sample's posture and, through the precise gap between its bottom and the belt, automatically and passively straightens the vertical sample to a flat position using the belt's movement; One component solves the three major problems of support, sample reception, and straightening, demonstrating a highly integrated and ingenious design.

[0028] 4. Actively utilize vibration: The sample is in a "pre-loosened" state in the vibrating blade cavity, which greatly reduces the ejection resistance. Synergistic triggering: The ejection action of the ejector rod can be synchronized with the cutting completion signal, forming a highly efficient and continuous action of "cutting and ejecting".
