Description

Technical Field

[0001] This invention relates to the field of oil-based coating processing technology, and in particular to a fully automatic quantitative stirring mixing vessel and control method for the production of oil-based coatings. Background Technology

[0002] Currently, fully automatic quantitative mixing tanks used in the production of oil-based coatings typically consist of a mixing tank body, a quantitative feeding device, and a PLC control system. The working method involves metering the raw materials such as resin, solvent, and additives using a flow meter or weighing sensor, and then controlling the mixing device according to a preset program to complete the mixing and dispersion. This type of equipment replaces manual weighing with automated batching, which to a certain extent improves the accuracy of the proportions and the consistency of batch production, and meets the basic requirements for mechanized mixing of various components of oil-based coatings. Existing mixing vessels are essentially passive execution units. Their weighing systems, due to the dual interference of rigid pipeline connections and stirring vibrations, can only provide metering signals with limited accuracy under static or intermittent operating conditions. They cannot achieve continuous and reliable perception of the material state inside the vessel during dynamic processing such as stirring and dispersion. As a result, the equipment lacks the ability to visualize and determine key process processes such as degassing and dispersion, and it also lacks early warning functions for potential hazards such as trace leaks and material anomalies. Furthermore, it is difficult to generate electronic batch records of continuous weight changes covering the entire process. Summary of the Invention

[0003] The purpose of this invention is to provide a fully automatic quantitative mixing vessel and control method for the production of oil-based coatings.

[0014] The present invention relates to a fully automatic quantitative mixing vessel and control method for oil-based coating production. In actual processing, a predetermined amount of raw material is first added to the processing vessel via the feeding device. After the raw material is added, the stirring component mixes the material inside the processing vessel. Then, the driving component moves the two supporting and stabilizing frames downwards. This downward movement of the supporting and stabilizing frames causes the guide bosses on both sides of the processing vessel to engage with two weight sensors. The two weight sensors detect the weight of the processing vessel and the raw material inside during the actual processing. After detection, the supporting and stabilizing frames on both sides, through the driving component, lift the processing vessel back up. At this point, the processing... The tops of the guide bosses on both sides of the vessel abut against the bottoms of the two pressing blocks. Then, the air pump continuously pressurizes the corresponding square cylinder, which allows the guide bosses on both sides of the processing vessel to be clamped and limited by the pressing blocks and the support and stabilizing frame, ensuring the stability of the mixing process. When the weight data needs to be checked again, the support and stabilizing frame can be moved down again by the drive component. This realizes the ability to weigh the vessel and raw materials during the processing through the provided components, upgrading the mixing vessel from a passive execution unit to an intelligent device with process status self-sensing and abnormality self-diagnosis capabilities, so as to achieve a comprehensive improvement from accurate measurement to process visualization, safety early warning and data traceability.

Detailed Implementation

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Please see Figures 1 to 11This invention provides a fully automatic quantitative mixing reactor for the production of oil-based coatings: It includes a processing table 101, a feeding device 102, and operating components. The operating components include a processing reactor 103, a discharge valve 104, a support and stabilizing frame 105, a weight sensor 106, a square cylinder 107, a lower pressure block 108, a pneumatic pump 109, a drive component, a stirring component, and a sealing component. The drive component includes a drive screw 201, a worm gear 202, a double-headed worm gear 203, and a rod drive mechanism 204. The stirring component includes an assembly table 301, a protective mesh frame 302, a stirring shaft 303, and a conversion component. The sealing component includes a top cover 401, a mounting plate 402, a sealing gasket 403, a rotating component, a snap-fit ​​component, and a self-adjusting component. The conversion component includes an inner gear sleeve 501, an outer gear 502, a toothed sliding plate 503, and a spring 504. The rotating component includes a lower extrusion frustum 601 and a toothed rotating table 600. 02 and a rotating motor 603, the rotating buckle component includes a rotating buckle ring frame 701, an arc-shaped toothed frame 702, an adapter gear 703 and a regulating motor 704, the self-adjusting component includes a top platform 801, a shifting frame 802, a shifting motor 803, a lifting frame 804, a screw lifting mechanism 805, an upper buckle frame 806 and a buckle cylinder 807. The aforementioned solution solves the problem that existing mixing kettles are essentially passive execution units, and their weighing systems, due to the dual interference of hard pipe connections and stirring vibrations, can only provide metering signals with limited accuracy under static or intermittent working conditions. They cannot achieve continuous and reliable perception of the state of materials in the kettle during dynamic processing such as stirring and dispersion. As a result, the equipment lacks the ability to visualize and determine key process processes such as degassing and dispersion, and also lacks early warning functions for potential hazards such as trace leaks and material abnormalities. Furthermore, it is difficult to generate continuous electronic batch records of weight changes covering the entire process.

[0032] Furthermore, the feeding device 102 is disposed on one side of the processing table 101, the processing vessel 103 is connected to the feeding device 102, the guide bosses on both sides of the processing vessel 103 are slidably connected to the processing table 101, the discharge valve 104 is installed at the bottom of the processing vessel 103, two support and stabilizing brackets 105 are slidably installed on both sides of the processing table 101, and the two support and stabilizing brackets 105 are respectively located at the bottom of the guide bosses on both sides of the processing vessel 103, two weight sensors 106 are respectively installed on both sides of the processing table 101, and the two weight sensors 106 are respectively located at the bottom of the guide bosses on both sides of the processing vessel 103, and two square cylinders 107 are fixedly installed on the processing vessel 103. On both sides of the platform 101, two square cylinders 107 are respectively located on the top of the guide bosses on both sides of the processing vessel 103. Each square cylinder 107 has a slidingly mounted pressing block 108 at its bottom. Each square cylinder 107 is also equipped with a corresponding air pressure pump 109 for regulating the internal air pressure. The two air pressure pumps 109 are respectively installed on both sides of the processing platform 101. The driving component is connected to the processing platform 101 and is used to drive the support and stabilizing frame 105 on both sides to move. The stirring component is connected to the processing vessel 103 and is used to uniformly stir the raw materials inside the processing vessel 103. The sealing component is connected to the processing vessel 103 and is used to seal and protect the top of the processing vessel 103.

[0033] Specifically, the feeding device 102, by setting a corresponding inlet and outlet pump, can introduce internal raw materials into the processing vessel 103. The feeding device 102 and the feeding channel of the processing vessel 103 are connected by a flexible hose. Since the processing vessel 103 needs to have a certain vertical movement space in order to better perform dynamic weighing, the flexible hose connection can avoid interfering with subsequent operations as much as possible. At the same time, multiple flexible hoses are provided, and multiple flexible hoses can correspond to multiple sets of independent feeding and storage structures. Multiple independent feeding structures can be integrated inside one feeding device 102 to enable the simultaneous introduction of multiple raw materials.

[0034] The discharge valve 104 at the bottom of the processing vessel 103 is used to complete the subsequent raw material discharge. The processing table 101 is provided with a corresponding sliding support structure to cooperate with the processing vessel 103. The two support and stabilizing brackets 105 are mainly used to lift the entire processing vessel 103. The lifting height of the two support and stabilizing brackets 105 should be as small as possible, just enough to ensure that the guide bosses on both sides of the processing vessel 103 do not contact the detection surfaces of the two weight sensors 106. At the same time, it can also avoid the processing vessel 103 from affecting normal processing due to excessive vertical movement during actual monitoring.

[0035] By controlling the weighing of the processing vessel 103 by moving the support frame 105 up and down, the weight sensor 106 can be kept under pressure for a long time. This is because the weight sensor 106 usually monitors weight through an internal sensor. If the elastic body (usually alloy steel or stainless steel) inside the sensor is under long-term stress, its microstructure will slowly rearrange, causing the output signal to drift over time. Therefore, by raising the support frame 105, the weight sensor 106 can be in an unloaded state when no detection is needed, thus improving the actual service life of the weight sensor 106.

[0036] The square cylinder 107, the pressing block 108, and the air pump 109 form a simple cylinder structure. The air pump 109 controls the air pressure inside the square cylinder 107, thereby cooperating with the corresponding support and stabilizing frame 105 to press and limit the raised processing vessel 103, preventing unnecessary shaking of the processing vessel 103 during actual processing.

[0037] In actual processing, the pre-weighed raw materials are first added to the processing vessel 103 via the feeding device 102. After the raw materials are added, the stirring component stirs and mixes the raw materials inside the processing vessel 103. Then, the driving component moves the two side support and stabilizing frames 105 downwards. The continuous downward movement of the two side support and stabilizing frames 105 causes the guide bosses on both sides of the processing vessel 103 to engage with the two weight sensors 106. The two weight sensors 106 detect the weight of the processing vessel 103 and the raw materials inside during the actual processing. After the detection is completed, the two side support and stabilizing frames 105 lift the processing vessel 103 back up via the driving component. At this time, the guide bosses on both sides of the processing vessel 103... The top abuts against the bottom of the two pressing blocks 108, and then the air pump 109 continuously pressurizes the corresponding square cylinder 107, which makes the guide bosses on both sides of the processing vessel 103 clamped and limited by the pressing blocks 108 and the support and stabilizing frame 105, ensuring the stability of the mixing process in the processing vessel 103. When the weight data needs to be checked again, the support and stabilizing frame 105 can be moved down again by the driving component. This realizes the ability to weigh the vessel and raw materials during the processing through the provided components, upgrading the mixing vessel from a passive execution unit to an intelligent device with process status self-sensing and abnormality self-diagnosis capabilities, so as to facilitate a comprehensive improvement from accurate measurement to process visualization, safety warning and data traceability.

[0038] Furthermore, the two drive screws 201 are respectively threadedly connected to the two support and stabilizing frames 105, and the two drive screws 201 are rotatably mounted on both sides of the processing table 101; each drive screw 201 has a worm gear 202 fixedly mounted at its bottom; the double-headed worm gear 203 is rotatably mounted on the bottom of the processing table 101, and the threads on both sides of the double-headed worm gear 203 are respectively engaged with the two worm gears 202; the rod drive mechanism 204 is connected to the processing table 101 and is used to drive the double-headed worm gear 203.

[0039] In this embodiment, both support and stabilizing frames 105 are driven by corresponding drive screws 201. The two drive screws 201 are engaged with the threads on both sides of the double-headed worm gear 203 through the worm wheel 202 at the bottom. Therefore, when the double-headed worm gear 203 rotates, it can drive the two drive screws 201 by driving the worm wheel 202 on both sides.

[0040] The double-headed worm gear 203 is driven by the link drive mechanism 204, which mainly consists of a gear chain and a motor. The motor, in conjunction with the corresponding gears and chains, drives the corresponding link to rotate. Since the link drive mechanism 204 is a very common drive structure, it will not be described in detail in this solution.

[0041] The rod drive mechanism 204 drives the double-headed worm gear 203 to rotate, and the rotation of the double-headed worm gear 203 drives the worm wheels 202 on both sides. The rotation of the worm wheels 202 on both sides realizes the synchronous drive of the two drive screws 201, and finally realizes the synchronous drive of the two support and stabilizing frames 105.

[0042] Furthermore, the assembly platform 301 is adapted to the holding groove provided inside the processing vessel 103; the protective net frame 302 is fixedly installed on the assembly platform 301; the stirring shaft 303 is rotatably installed on the assembly platform 301; the conversion component is connected to the assembly platform 301 and is used to cooperate with the corresponding structure to drive the stirring shaft 303 to rotate.

[0043] Furthermore, the inner gear sleeve 501 is fixedly installed in the circular groove at the top of the stirring shaft 303; the outer gear 502 is sleeved on the outer ring at the top of the stirring shaft 303; the toothed slide plate 503 is slidably installed in the assembly table 301, and the toothed slide plate 503 is provided with a toothed platform that engages with the outer teeth of the outer gear 502; the two sides of the spring 504 are respectively connected to the toothed slide plate 503 and the assembly table 301.

[0044] In this embodiment, the inner ring of the top of the processing vessel 103 is provided with a corresponding retaining groove to cooperate with the assembly platform 301. The protective net frame 302 is fixedly installed on both sides of the assembly platform 301. After the assembly platform 301 and the retaining groove of the processing vessel 103 are assembled and engaged, the two protective net frames 302 can completely cover the top of the processing vessel 103, completely eliminating the possibility of operators and tools accidentally falling into the mixing area, making it safer for operators to perform maintenance and inspection later.

[0045] The assembly platform 301 is provided with a corresponding stirring shaft 303. The inner toothed sleeve 501 is fixed in the inner groove at the top of the stirring shaft 303, and the outer outer gear 502 is fixedly installed on the outer ring at the top of the stirring shaft 303. There are two sets of toothed sliding plates 503 and springs 504. The two toothed sliding plates 503 are provided with corresponding toothed platforms that cooperate with the outer teeth of the outer outer gear 502. When the toothed sliding plates 503 are not subjected to any external force, the toothed sliding plates 503 will be in an upward state under the action of the springs 504. At this time, the toothed sliding plates 503 can cooperate with the outer outer gear 502 in the corresponding state through the set toothed platforms. In this way, the outer outer gear 502 will be limited by the two toothed sliding plates 503. Only when the two toothed sliding plates 503 are in a downward state will the rotation of the outer outer gear 502 and the stirring shaft 303 not be affected by the two toothed sliding plates 503.

[0046] Furthermore, the top cover 401 is disposed on the top of the processing vessel 103; the insertion platform 402 is fixedly installed on the processing vessel 103; the sealing gasket 403 is disposed at the position where the top cover 401 contacts the top surface of the processing vessel 103; the rotating component is connected to the top cover 401 and is used to drive the stirring shaft 303 to rotate; the snap fastener is connected to the top cover 401 and is used to lock and limit the top cover 401; the self-adjusting component is connected to the top cover 401 and is used to adjust the mating position of the top cover 401.

[0047] Furthermore, the lower extrusion frustum 601 is fixedly installed on the top cover 401 on the side near the toothed slide plate 503; the toothed turntable 602 is rotatably installed on the top cover 401, and the toothed column at the bottom of the toothed turntable 602 is adapted to the toothed groove of the inner toothed sleeve 501; the output shaft of the drive motor 603 is connected to the toothed turntable 602, and the drive motor 603 is fixedly installed on the top cover 401.

[0048] Furthermore, the rotating ring frame 701 is rotatably mounted inside the top cover 401; the arc-shaped toothed frame 702 is fixedly mounted on the rotating ring frame 701; the adapter gear 703 meshes with the arc-shaped toothed frame 702 and is rotatably mounted on the top cover 401; the output shaft of the regulating motor 704 is connected to the adapter gear 703, and the regulating motor 704 is fixedly mounted on the top cover 401.

[0050] In this embodiment, the top cover 401 is disposed on the top of the processing vessel 103 to cover and seal the top opening of the processing vessel 103. The top cover 401 is also provided with a corresponding sealing gasket 403 to prevent gas leakage. At the same time, the outer ring of the top cover 401 is provided with a corresponding notch to cooperate with the insertion platform 402 of the processing vessel 103.

[0051] The top cover 401 is provided with a corresponding lower extrusion platform 601, a gear-shaping rotary table 602 and a rotating motor 603 on the side that contacts and cooperates with the top of the processing vessel 103. There are two lower extrusion platforms 601, which are used to extrude the corresponding toothed slide plate 503 on the assembly table 301. The gear-shaping rotary table 602 is used to cooperate with the inner toothed sleeve 501.

[0052] After the top cover 401 is installed and engaged with the top of the processing vessel 103, the gear-shaping turntable 602 will be inserted into the inner gear sleeve 501. At the same time, the lower extrusion platform 601 will squeeze the two toothed sliding plates 503 downward. When the drive motor 603 drives the gear-shaping turntable 602 to rotate, the stirring shaft 303 will follow the gear-shaping turntable 602 to rotate through the engagement of the inner gear sleeve 501 and the gear-shaping turntable 602, thereby driving the stirring shaft 303.

[0053] In this design, the stirring shaft 303 and the related drive structure are designed as separate units. The stirring shaft 303 and the assembly platform 301 are a single module. The drive structure for driving the stirring shaft 303 and the sealing structure formed by the top cover 401 are also a single module. This allows operators to quickly change the actual stirring structure of the stirring shaft 303, simply by keeping the inner toothed sleeve 501 paired with the toothed turntable 602.

[0054] When the top cover 401 and the corresponding mechanism need to be removed from the top of the processing vessel 103, the lower extrusion platform 601 will move upward with the top cover 401. At this time, the toothed sliding plate 503 will also spring back to its original position under the action of the corresponding spring 504. At this time, the toothed turntable 602 only needs to drive the stirring shaft 303 to rotate to the angle where the outer gear 502 can cooperate with the toothed sliding plate 503 in advance. The toothed sliding plate 503 will then move upward to lock the corresponding outer gear 502, preventing the stirring shaft 303 from deflecting and facilitating the subsequent insertion and cooperation between the toothed turntable 602 and the inner gear sleeve 501.

[0055] The insertion platform 402 is provided with a corresponding arc-shaped through groove, and the rotating buckle frame 701 is provided with a locking arc platform that cooperates with the arc-shaped through groove of the insertion platform 402. When the top cover 401 is completely fitted onto the top of the processing vessel 103, the rotating buckle frame 701 can be rotated to cooperate with the corresponding insertion platform 402, thereby completing the locking and limiting of the top cover 401.

[0056] The rotating ring frame 701 is provided with an arc-shaped toothed frame 702 that engages with the adapter gear 703. The adapter gear 703 is driven by the regulating motor 704, so that the regulating motor 704 can drive the adapter gear 703 to drive the arc-shaped toothed frame 702 and the rotating ring frame 701. Since the rotating ring frame 701 only needs to rotate at a specific angle when rotating and locking, the arc-shaped toothed frame 702 is an incomplete external tooth structure, and the adapter gear 703 only needs to drive the arc-shaped toothed frame 702 to rotate within the corresponding range.

[0057] The top cover 401 is provided with four contact platforms. The upper belt fastening frame 806 is provided with four belt contact platforms that cooperate with the four contact platforms of the top cover 401. The upper belt fastening frame 806 is driven by the belt cylinder 807. The upper belt fastening frame 806 is also slidably mounted on the lifting frame 804. The lifting frame 804 is slidably mounted on the shifting frame 802. The shifting frame 802 is driven by the shifting motor 803. The lifting frame 804 is driven by the lead screw lifting mechanism 805. The lead screw lifting mechanism 805 is composed of a lead screw and a motor. The motor drives the lead screw to rotate, and the rotation of the lead screw completes the driving of the corresponding plate.

[0058] Since the processing vessel 103 needs to have a certain range of vertical movement when performing weight detection, the top cover 401 also needs to maintain a certain range of vertical movement after completion. Therefore, by setting the upper buckle bracket 806, the top cover 401 can still have a certain range of vertical movement after installation. When disassembling and installing the top cover 401, the upper buckle bracket 806 will be driven by the buckle cylinder 807 to make the top cover 401 fit tightly against the bottom of the lifting frame 804, so that the top cover 401 will not shake unnecessarily when the lifting frame 804 moves the top cover 401 up and down.

[0059] The lifting frame 804 can move up and down to press the top cover 401 into the processing vessel 103, and can also pull the top cover 401 out from the top of the processing vessel 103, realizing the automated disassembly and assembly of the top cover 401. At the same time, the rotation of the transfer frame 802 on the top platform 801 can transfer the disassembled top cover 401 to another location, making it convenient for operators to observe and operate the inside of the processing vessel 103.

[0060] Preferably, the working assembly provided by the present invention further includes an extension guide 901, a lifting bracket 902, a lead screw lifting mechanism 903, an arc-shaped cylinder 904, an arc-shaped gripper 905, and a regulating pump 906.

[0061] Furthermore, the extension guide 901 is fixedly mounted on the transposition frame 802; the lifting bracket 902 is slidably mounted on the extension guide 901; the lead screw lifting mechanism 903 is connected to the lifting bracket 902 and is used to drive the lifting bracket 902 to move; two arc-shaped cylinders 904 are fixedly mounted on both sides of the lifting bracket 902; each arc-shaped cylinder 904 is slidably mounted with an arc-shaped gripper 905; the regulating pump 906 is fixedly mounted on the lifting bracket 902, and the regulating pump 906 is connected to the two arc-shaped cylinders 904 for synchronously regulating the pressure inside the two arc-shaped cylinders 904.

[0062] In this embodiment, the extended guide frame 901 is mounted on the shifting frame 802. The mating position of the extended guide frame 901 and the lifting frame 804 can be changed by rotating the shifting frame 802. The lifting bracket 902 mounted on the extended guide frame 901 is driven by the screw lifting mechanism 903. The screw lifting mechanism 903 has the same structural principle as the screw lifting mechanism 805. Two sets of arc-shaped cylinders 904 and arc-shaped grippers 905 are also mounted on the lifting bracket 902. The corresponding structure composed of the two arc-shaped cylinders 904 and the arc-shaped grippers 905 is regulated by a regulating pump 906.

[0063] The arc-shaped gripper 905 is adapted to the gripper arc groove provided on the assembly table 301. When the lifting bracket 902 is in contact with the top of the corresponding assembly table 301 through the rotation of the shifting frame 802, the two arc-shaped grippers 905 can extend outward through the control of the internal pressure of the arc-shaped cylinder 904 by the regulating pump body 906, thereby cooperating with the gripper sliding arc groove on the top of the assembly table 301 to clamp the assembly table 301. This allows the corresponding assembly table 301 to be continuously lifted by the movement of the lifting bracket 902 and finally pulled out from the processing vessel 103. Subsequently, the corresponding assembly table 301 and the corresponding mechanism can be reinstalled into the processing vessel 103 using the above principle, making it more convenient and faster for operators to disassemble and replace the assembly table 301 and its corresponding stirring structure.

[0064] Please see Figure 12 A fully automated quantitative stirring control method for the production of oil-based coatings, employing the aforementioned fully automated quantitative stirring mixing vessel for oil-based coating production, includes the following steps. S1: A fixed amount of the corresponding raw material is added to the processing vessel 103 through the feeding device 102; S2: After the raw materials are added, the stirring component can stir and mix the raw materials inside the processing vessel 103; S3: Then, the driving component drives the two side support and stabilizing frames 105 to move down. The continuous downward movement of the two side support and stabilizing frames 105 causes the guide bosses on both sides of the processing vessel 103 to cooperate with the two weight sensors 106. S4: The weight of the processing vessel 103 and the raw materials inside are detected by the two weight sensors 106 during the actual processing. S5: After the test is completed, the support and stabilizing frame 105 on both sides will lift the processing vessel 103 again through the driving component. At this time, the top of the guide boss on both sides of the processing vessel 103 will abut against the bottom of the two pressing blocks 108. S6: Then, by continuously pressurizing the corresponding square cylinder 107 with the air pump 109, the guide bosses on both sides of the processing vessel 103 are clamped and limited by the pressing block 108 and the support and stabilizing frame 105, so as to ensure the stability of the mixed processing of the processing vessel 103. S7: When it is necessary to check the weight data again, simply move the support and stabilizing frame 105 down again by driving the drive component.

[0065] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
