Description

Technical Field

[0001] This invention relates to the field of organic pigment packaging technology, specifically to a storage and packaging device for an organic pigment production line. Background Technology

[0002] The quality and precision of organic pigment packaging directly affect its storage, transportation, and usage. Traditional manual alignment of material barrels is inefficient and inaccurate, easily leading to pigment contamination of the barrel opening, and single-machine operation is prone to errors. During the feeding process, organic pigments are prone to absorbing moisture, clumping, and sticking to the barrel walls. Existing equipment relies on gravity or simple stirring, which cannot effectively solve this problem, resulting in uneven feeding, inaccurate measurement, and raw material waste, which also affects the quality of subsequent packaging. Furthermore, the impact of organic pigment feeding causes barrel displacement and tilting, and fixing can cause barrel deformation and leakage, resulting in insufficient equipment flexibility and stability. The capping and screwing processes are mostly rigid transmissions without buffer protection, which can easily damage the seal due to excessive screwing force or impact, affecting the sealing effect and causing pigment deterioration and leakage.

[0003] In summary, existing packaging equipment has many technical defects and cannot meet the needs of modern production. Developing a device that integrates high-precision positioning, stable feeding, self-adaptive fixing, and safe sealing has become an urgent need in the industry. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention constructs a cross-center positioning system for rectangular material buckets through the synergistic effect of a vision sensor and a fixing device, completely solving the alignment deviation problem caused by relying on manual or single mechanical identification in traditional packaging. The vision sensor is embedded in the bottom of the circular support frame, which can accurately identify the center of the outer wall of the material bucket and provide a Y-axis positioning signal for the robotic arm. The fixing device drives two fixing plates to move closer synchronously through a second drive component, completing the center positioning and clamping of the material bucket along the X-axis. This dual-axis positioning method enables high-precision alignment between the material bucket inlet and outlet and the output port of the feeding device, effectively avoiding the problem of pigment spilling onto the threaded part of the bucket opening, providing a solid guarantee for subsequent sealing quality from the source of packaging. At the same time, this positioning structure can be adapted to rectangular material buckets of different specifications through the transmission of gears and racks and the feedback control of pressure sensors, greatly improving the versatility of the device.

[0016] 2. To address the problem of organic pigments easily clumping and sticking to the inner wall of storage tanks due to environmental humidity and other factors, this invention innovatively designs a cooperative structure between the scraper and the drive assembly in the feeding device, significantly improving the feeding quality and accuracy. The first drive assembly, through a flat brake motor fixed by an L-shaped support plate, drives the driven large gear to rotate via a driving pinion, causing the scraper to continuously scrape along the inner wall of the organic dye storage tank, effectively breaking up pigment clumps and removing pigments adhering to the inner wall, ensuring that the pigment falls in a uniform state. The conical structure at the bottom of the storage tank further assists feeding with gravity, and together with the precise control of the automatic valve, achieves stable pigment output.

[0017] 3. The fixing device of the present invention, through the electrical connection between the pressure sensor and the second flat brake motor, constructs an adaptive barrel fixing mechanism, effectively solving the problem of barrel deformation caused by uncontrolled clamping force in traditional fixing methods. Two pressure sensors are symmetrically embedded in the opposite surfaces of the fixing plate, which detects the fixing force on the outer wall of the barrel in real time. When the pressure reaches the set threshold, a signal is immediately fed back to the second flat brake motor to stop its drive, ensuring that the fixing force is within a safe range. During the feeding process, it can effectively counteract the impact force generated by the falling pigment, preventing barrel displacement or tilting. This fixing structure not only ensures the structural integrity of the barrel throughout the packaging process, but also enhances the applicability of the device by adapting to the adjustment capability of barrels of different specifications.

[0018] 4. This invention incorporates a spring-buffered protective component in the packaging device, effectively solving the problem of seal damage caused by excessive tightening force or inertial impact during traditional sealing processes, significantly improving the quality of sealed packaging. The protective component, through the cooperation of a spring and an arc-shaped slider within an arc-shaped plate, forms an elastic clamping structure, with the spring's pulling force precisely matched to the sealing force. When the third drive component drives the threaded rod to rotate and tighten the automatic mechanical clamp, if the tightening force exceeds the set value, the excess inertial impact force will be absorbed by the spring, and the arc-shaped slider extends along the groove to achieve buffering, preventing the seal from directly bearing overload. After tightening, the spring uses its own elasticity to reset the component, ensuring the normal operation of subsequent tasks. Furthermore, the third drive component, through the coordinated action of the second electric push rod and the brake motor, converts the rotational motion into the axial linear motion of the threaded rod, making the sealing process smooth and controllable, further ensuring the sealing effect and improving packaging quality and precision.

One end of the connecting block 571 is located at the center of the bottom end of one clamping surface of the automatic mechanical clamp 56; the arc-shaped plate 572 is located at the other end of the connecting block 571, with a slide groove 573 at one end of the arc-shaped plate 572 and a groove 574 at one corner of one end of the arc-shaped plate 572, the groove 574 extending into the slide groove 573; one end of the spring 575 is located at the center of one end of the inner wall of the slide groove 573, and the pulling force of the spring 575 is the same as the fixing force of the sealing cap when tightened, its purpose being to buffer and protect the sealing cap from the tightening connection between the rectangular material bucket inlet and outlet, preventing damage from excessive tightening force. The sealing cap is damaged; one end of the arc-shaped slider 576 is set inside the other end of the spring 575, and the arc-shaped slider 576 is embedded in the other end of the slide groove 573. The spring 575 can move along the inner wall of the slide groove 573. The arc-shaped slider 576, through its cooperation with the spring 575, is used to protect the sealing quality of the sealing cap; the connecting plate 577 is set at the other end of the arc-shaped slider 576, one end of the connecting plate 577 is embedded in the groove 574, and the connecting plate 577 can move within the groove 574; the arc-shaped clamping plate 578 is set at one end of the connecting plate 577, and one side of the outer wall of the arc-shaped clamping plate 578 contacts one side of the outer wall of the arc-shaped plate 572. The side of the arc-shaped clamping plate 578 that contacts the sealing cap has anti-slip texture to improve the clamping and fixing of the sealing cap.

[0045] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, and the specific work is as follows:

[0046] Step 1. The robotic arm 2 grips the rectangular container of organic pigment onto the moving belt of the support platform 11 at the bottom of the automatic valve 34, and positions it at the center of the outer wall of the rectangular container. The visual sensor 32 and the fixing device 4 work together to achieve center positioning on the Y-axis of the top view plane. Then, the second flat brake motor 451 drives the two fixing plates 47 to move closer to each other simultaneously, and performs center positioning on the X-axis of the top view plane. At this time, the inlet and outlet of the rectangular container are highly aligned vertically with the discharge port of the first drive component 35, laying a high-quality foundation for subsequent sealing and packaging. Traditional methods rely solely on manual or robotic arm 2 for alignment, lacking precise cross-shaped positioning on the X and Y axes. Small deviations can easily cause pigment to scatter onto the threads of the inlet and outlet of the rectangular container, seriously affecting the sealing and packaging quality. This invention improves the sealing and packaging quality from the source through dual-axis high-precision positioning and has a certain degree of versatility, applicable to rectangular containers of any size.

[0047] Step 2. The first flat brake motor 352 can drive the scraper 36 to rotate and scrape along the inner wall of the organic dye storage tank 33 to prevent the organic dye from sticking to the inner wall of the organic dye storage tank 33 due to high ambient humidity, thereby affecting the quality of material feeding.

[0048] Step 3. The two fixing plates 47 are not only used for center positioning of the rectangular material bucket on the X-axis, but also for fixing the bucket body by setting pressure through the cooperation of the two pressure sensors 48 and the second flat brake motor 451. This not only prevents the bucket body from deforming, but also adapts to rectangular material buckets of different specifications. During the feeding process, it can counteract the impact of organic pigments and prevent the bucket body from shifting or tilting, causing the pigments to scatter at the threaded part of the bucket opening.

[0049] Step 4. The rectangular bucket with the finished loading is conveyed by the conveyor belt conveyor device 12. During the conveying process, the robotic arm 2 places a sealing cap on the top of the rectangular bucket inlet and outlet. Then the robotic arm 2 clamps the rectangular bucket to the bottom of the automatic valve 34 and onto the moving belt of the support platform 11, and performs the loading action as described above.

[0050] Step 5. The barrels to be sealed and packaged are conveyed by the conveying device 12 to the center between the bottoms of the two protective components 57, and are arranged at equal intervals with the barrels to be loaded and several barrels in the middle. The loading and sealing and packaging structures are operated in parallel, and the corresponding barrels are processed simultaneously to improve the overall processing efficiency.

[0051] Step 6. The second electric push rod 541 and the brake motor 544 cooperate to drive the threaded rod 55 to rotate clockwise along the thread and move downward in the nut 52. This causes the two protective components 57 to be spaced and fitted onto the outer ring of the sealing cap. The automatic mechanical clamp 56 then drives the two protective components 57 to clamp the sealing cap. Finally, the second electric push rod 541 and the brake motor 544 cooperate to drive the sealing cap to complete the screw-sealing packaging of the barrel opening. Traditional screw-sealing is prone to damage to the seal due to the inertia of the screw-sealing after the fixing force. This invention avoids this problem through the following structure: When the screw-sealing reaches the set value, the inertia exceeding the value is absorbed by the two buffer springs 575. This causes the two arc-shaped sliders 576 to extend from the inner part of the mounting base groove 573 to achieve buffering. The tension of the springs 575 matches the screw-sealing fixing value. When the two protective components 57 are fixed and reset, the two springs 575 can rebound and reset through their own elasticity, thereby protecting the connection structure between the barrel opening and the sealing cap, preventing damage to the seal, and improving the quality of the sealed packaging.
