Description

Technical Field

[0001] The present invention relates to a masterbatch performance detection technology, and in particular to a masterbatch automatic detection system and method. Background Art

[0002] Masterbatch is a highly concentrated color concentrate typically composed of inorganic or organic pigments, additives, and a carrier resin (usually a polymer). It typically exists in granular form and is primarily used for coloring materials such as plastics and rubber. In the plastics industry, masterbatch serves as an important colorant and is widely used in the production of various plastic products. Currently, masterbatches are filled with carbon black to improve their heat resistance, dimensional stability, rigidity, and hardness. As the amount of carbon black added increases, its tensile strength and impact resistance decrease dramatically. The amount of carbon black added varies depending on its role in the plastic.

[0003] Chinese invention patent publication number CN112345577B discloses a system and method for automatically detecting masterbatches. Under the action of an automatic feeding device, a combustion boat placed on the feed end of the automatic feeding device is automatically transferred from the feed end of the quartz tube into the quartz tube. The entire process enables the combustion boat to be automatically fed each time, thereby improving detection efficiency. The automatic feeding of the combustion boat is completed by the sequential linkage of the low-level feeding mechanism, the vertical feeding mechanism, the high-level feeding mechanism, the lifting assembly, and the horizontal feeding mechanism, effectively improving detection efficiency.

[0004] When the existing equipment is in use, the masterbatch may be on the combustion boat during the transportation process.

[0005] Accumulation, overlapping or mutual adhesion may occur, affecting the accuracy of detection. At the same time, the shape of the masterbatch may be irregular, or there may be some tiny impurities. Since the color recognition of the masterbatch is very dependent on a stable lighting environment, foreign matter or small particles of impurities may not be discovered in time during detection, resulting in deviations in subsequent test results. Therefore, an automatic masterbatch detection system and method have been developed. Summary of the Invention

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, unless otherwise expressly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Example 1: Please refer to Figures 1-10 A masterbatch automatic detection system includes a base 1, a support column 11 is symmetrically fixedly provided at the end of the base 1, and a sieve plate 12 is fixedly installed on one side of the support column 11.

[0045] In this solution, inclined transmission plates are provided on both sides of the sieve plate 12 to stabilize the flow of the material and cooperate with the outlet component 2 to screen out small particle impurities remaining inside the material to avoid errors during detection.

[0046] Furthermore, a dispersion component 3 is assembled at the end of the sieve plate 12, and the material cleaned by the outlet component 2 is smoothed by the dispersion component 3; wherein, the dispersion component 3 includes a clamping plate 31 clamped to the sieve plate 12, and a transmission member 32 is fixedly installed at the end of the clamping plate 31, and a transmission ring 34 is fixedly installed at the output end of the transmission member 32, and a protective block 35 is fixedly installed at the end of the transmission ring 34.

[0047] In this embodiment, the transmission member 32 is a device with power output such as a motor, and is connected to an external control device. When the transmission member 32 is started, it synchronously drives the transmission ring 34 fixedly installed at its output end to rotate. Since the protective block 35 is fixedly installed at the end of the transmission ring 34, it drives the protective block 35 to move.

[0048] The cross section of the protection block 35 is concave, and a protection rod is symmetrically provided on one side of the protection block 35 to limit the movable rod 371.

[0049] Furthermore, a rotating shaft 36 is rotatably mounted on the inner wall of the transmission ring 34 , and a dispersion plate 361 is fixedly mounted on the end of the rotating shaft 36 , and the materials are dispersed by the dispersion plate 361 .

[0050] Specifically, when the rotating shaft 36 is rotated by force, the dispersion plate 361 fixedly installed at its end is driven to rotate, thereby breaking up the screened material so that the entire material is in a flat state, which is convenient for subsequent detection.

[0051] Furthermore, an extension rod 362 is fixedly mounted on one end of the rotating shaft 36 away from the dispersion plate 361 , and an arcuate groove 33 is formed on the inner wall of the clamping plate 31 , and the inner wall of the arcuate groove 33 is slidably connected to the outer surface of the end of the extension rod 362 .

[0052] Specifically, elastic baffles are provided on both sides of the inner wall of the arc-shaped groove 33, so that when the extension rod 362 fixedly mounted on the rotating shaft 36 moves to the maximum position, the extension rod 362 is limited by the elastic baffle, wherein the end of the extension rod 362 is L-shaped, and when the extension rod 362 moves in the reverse direction, the extension rod 362 is locked by the elastic baffle, thereby driving the extension rod 362 to rotate, and cooperating with the rotating shaft 36 fixedly connected to its end to drive the dispersion plate 361 to swing, thereby flattening the material.

[0053] Furthermore, a movable cylinder 37 is clamped on the outer surface of the rotating shaft 36, and a movable rod 371 is slidably installed on the inner wall of the movable cylinder 37. An elastic member 372 is sleeved on the outer surface of the movable rod 371, and one end of the elastic member 372 is connected to the end of the movable rod 371, and the other end is connected to the end of the movable cylinder 37.

[0054] Specifically, the elastic member 372 is an elastic component such as a spring, and the movable cylinder 37 rotates synchronously with the rotating shaft 36. When the extension rod 362 is rotated to an appropriate angle under force, the extension rod 362 is pulled to rotate continuously by the force of the elastic member 372 until the movable rod 371 is attached to the protective rod and stops, thereby reciprocating the operation to continuously spread the material.

[0055] Furthermore, the end of the movable rod 371 is rotatably mounted with a connecting rod 38, and the end of the connecting rod 38 is rotatably mounted with a limit rod 39. The end of the transmission ring 34 is fixedly mounted with a limit block 341, and the outer surface of the end of the limit block 341 is rotatably connected to the end of the limit rod 39.

[0056] Specifically, the movable rod 371 is limited by the limiting rod 39, and the limiting block 341 is used to support the movable rod 371 during rotation, ensuring that it remains smooth during rotation.

[0057] Furthermore, the outlet assembly 2 is mounted on the end of the support column 11 and controls the material flow rate. The outlet assembly 2 includes a positioning plate 21 fixedly connected to the support column 11. The end of the positioning plate 21 defines a positioning slot 23, and a positioning block 24 is slidably mounted on the inner wall of the positioning slot 23. A driving member 22 is fixedly mounted on the end of the positioning plate 21. A driving rod 221 is fixedly mounted on the output end of the driving member 22. The end of the driving rod 221 is connected to the end of the positioning block 24.

[0058] In this embodiment, the driving member 22 is a device with power output such as a motor, and is connected to an external control device. When the driving member 22 is started, it synchronously drives the driving rod 221 fixedly installed at its end to move, and cooperates with the driving rod 221 to drive the positioning block 24 to move along the inner wall of the positioning groove 23 until it reaches the optimal position and stops.

[0059] Furthermore, a connecting block 241 is fixedly mounted on the end of the positioning block 24 , and an adjusting block 25 is rotatably mounted on the end of the connecting block 241 . An adjusting slot 251 is formed on the end of the adjusting block 25 .

[0060] Specifically, when the positioning block 24 moves, it synchronously drives the connecting block 241 fixedly mounted on its end to move, and simultaneously drives the adjusting block 25 rotatably mounted on its end to move.

[0061] Furthermore, an adjusting rod 26 is slidably installed on the inner wall of the adjusting groove 251, an adjusting plate 261 is fixedly installed on the end of the adjusting rod 26, a locking block 262 is fixedly installed on the end of the adjusting plate 261, and a support plate 27 is fixedly installed on the end of the base 1, and the end of the support plate 27 is rotatably connected to the outer surface of the locking block 262.

[0062] Specifically, when the adjustment block 25 moves, the adjustment slot 251 drives the adjustment rod 26 slidably installed on its inner wall to move. Since the outer surface of the locking block 262 is rotatably connected to the end of the support plate 27, when the adjustment block 25 moves, the entire adjustment plate 261 is driven to cooperate with the locking block 262 to flip around the support plate 27. By controlling the rotation angle, the overall flow rate of the material is controlled.

[0063] Furthermore, the end of the positioning plate 21 is clamped with a movable plate 28, and the end of the movable plate 28 is symmetrically provided with a movable groove 281. A cleaning block 282 is slidably mounted on the inner wall of the movable groove 281. A power member 29 is fixedly mounted on the end of the movable plate 28, and a transmission gear 291 is fixedly mounted on the output end of the power member 29. The outer surface of the transmission gear 291 meshes with the outer surface of the cleaning block 282.

[0064] Specifically, the power part 29 is a device with power output such as a motor, and is connected to an external control device. When the power part 29 is started, it synchronously drives the transmission gear 291 fixedly installed at its output end to rotate. Since the outer surface of the transmission gear 291 is engaged with the outer surface of the cleaning block 282, when the transmission gear 291 rotates, the two cleaning blocks 282 are driven to move back and forth, wherein one side of the cleaning block 282 is provided with a convex tooth corresponding to the transmission gear 291, and the lower end of the cleaning block 282 is provided with a brush or other cleaning component, which reduces the cleaning of material accumulation through reciprocating movement and removes small particles of impurities remaining inside.

[0065] The control device can use a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MCU), consisting of an arithmetic unit, a controller, memory, and input / output devices, equivalent to a miniature computer. Compared to the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantages are its small size, allowing it to be placed inside the instrument, low memory capacity, simple input / output interfaces, and low functional consumption.

[0066] Example 2: A method for automatically detecting masterbatch, using any of the above detection systems, the detection method comprises the following steps:

[0067] S1. The adjusting block 25 moves, and the adjusting slot 251 drives the adjusting rod 26 slidably mounted on its inner wall to move. Since the outer surface of the locking block 262 is rotatably connected to the end of the supporting plate 27, when the adjusting block 25 moves, the entire adjusting plate 261 is driven to rotate around the supporting plate 27 in cooperation with the locking block 262. By controlling the rotation angle, the overall flow rate of the material is controlled;

[0068] S2. The transmission gear 291 rotates, driving the two cleaning blocks 282 to reciprocate. One side of the cleaning block 282 is provided with a convex tooth corresponding to the transmission gear 291, and the lower end of the cleaning block 282 is provided with a brush or other cleaning component. The reciprocating movement reduces the cleaning of material accumulation and removes small particles of impurities remaining inside.

[0069] S3. When the extension rod 362 moves in the reverse direction, the extension rod 362 is locked by the elastic baffle, thereby driving the extension rod 362 to rotate, and cooperating with the rotating shaft 36 fixedly connected to its end to drive the dispersion plate 361 to swing, thereby flattening the material.

[0070] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
