Description

Technical Field

[0001] This invention relates to the field of pigment sample preparation technology, and in particular to a fully automated, high-precision pigment sample preparation device. Background Technology

[0002] In traditional printing processes, the preparation of color paste samples is mostly done manually, which obviously suffers from drawbacks such as high labor intensity, low work efficiency, poor paste accuracy, and low precision. With the improvement of process automation, automated color paste sample preparation machines are now widely used for paste preparation.

[0003] Existing automatic mixing machines generally only include automatic cup dropping and automatic cup feeding mechanisms. Empty cups are placed manually on the cup feeding conveyor belt, which then transports the empty cups into the equipment. The cup feeding moving tray then transports the empty cups to the weighing and discharging position, where high-precision valves are used for accurate proportioning. Afterward, the cups are transported to the cup discharge conveyor belt, where manual personnel move them to the mixing mechanism for mixing.

[0004] As can be seen from the foregoing, the existing automated color paste sample preparation machine is a split design, that is, the two process steps of ingredient preparation and mixing are set on two separate devices. This increases the manual maintenance cost of the equipment, resulting in low work efficiency and cumbersome operation. Summary of the Invention

[0033] like Figures 1 to 5As shown, the present invention relates to a fully automatic high-precision color paste sample preparation device, including a frame 1, and an automatic cup dropping mechanism 2, a cup transferring mechanism 3, a color mixing mechanism 4, a stirring mechanism 5, and a cup dispensing mechanism 6, all of which are arranged on the frame 1. The automatic cup dropping mechanism 2, the color mixing mechanism 4, the stirring mechanism 5, and the cup dispensing mechanism 6 are arranged sequentially along the length of the frame 1.

[0034] The automatic cup dropping mechanism 2 includes a cup placement platform 21, a cup storage component 22 for storing multiple cups stacked together, and a cup retrieval component 23 for retrieving cups one by one to the cup placement platform 21. The cup placement platform 21, the cup storage component 22, and the cup retrieval component 23 are all connected to the frame 1.

[0035] The color mixing mechanism 4 includes a mixing platform 41 fixed on the frame 1, an electronic scale on the mixing platform 41, and a mixing component 42 above the electronic scale. The mixing component 42 includes several color paste storage tanks, several thickener storage tanks, several color paste needle valves 421 arranged side by side, several thickener needle valves 422 arranged side by side, a discharge cylinder 423, and a gripper 424. The several color paste storage tanks and several color paste needle valves 421 are connected in a one-to-one correspondence, and the several thickener storage tanks and several thickener needle valves 422 are connected in a one-to-one correspondence. The gripper 424 is used to hold the handle of the color paste needle valve 421 or the thickener needle valve 422. The discharge cylinder 423 is used to drive the gripper 424 to rise and fall, thereby controlling the opening and closing of the color paste needle valve 421 or the thickener needle valve 422.

[0036] The stirring mechanism 5 is used to stir the color paste and thickener in the cup;

[0037] The cup dispensing mechanism 6 is used to dispense the cups containing the prepared color paste one by one;

[0038] The cup-moving mechanism 3 is used to move the cups on the cup-placement platform 21 of the automatic cup-dropping mechanism 2 to the color-mixing mechanism 4, the stirring mechanism 5, and the cup-dispensing mechanism 6 in sequence.

[0039] In this invention, the automatic cup dropping mechanism 2 can remove stacked cups one by one, and then the cup transfer mechanism 3 sequentially sends the cups to the color mixing mechanism 4, the stirring mechanism 5, and the cup dispensing mechanism 6, thereby injecting color paste and thickener into the cups to prepare the color paste, then stirring and mixing, and finally the cup containing the finished color paste is sent out by the cup dispensing mechanism 6. The preparation of color paste is completed in an automated manner. The automatic cup dropping mechanism 2, the cup transfer mechanism 3, the color mixing mechanism 4, the stirring mechanism 5, and the cup dispensing mechanism 6 are all arranged in the frame 1, which makes the fully automatic high-precision color paste sample preparation device more integrated, saves manpower, makes the color paste preparation work more convenient, and improves work efficiency.

[0040] In this embodiment, the cup storage assembly 22 includes at least three vertically arranged limiting rods 221, and a limiting space for vertically stacking several cups is formed between the at least three limiting rods 221. The cup retrieval assembly 23 includes a cup retrieval base 231, a first cup retrieval arm 232, a second cup retrieval arm 233, a cup retrieval cylinder 234, and a cup retrieval robot 235. The first cup retrieval arm 232 extends forward from both sides of the front end of the cup retrieval base 231, and the second cup retrieval arm 233 extends forward from both sides of the front end of the cup retrieval base 231, with the second cup retrieval arm 233 located below the first cup retrieval arm 232. A gap is formed between the arms 233 for the upper edge of the cup to pass through. The length of the second cup-picking arm 233 is greater than that of the first cup-picking arm 232. The front end of the first cup-picking arm 232 is pointed. Both sides of the two second cup-picking arms 233 facing each other and the end near the cup-picking seat 231 are provided with a relief groove 236 for the upper edge of the cup to pass downward. The cup-picking cylinder 234 is fixed on the frame 1, and the telescopic rod of the cup-picking cylinder 234 is fixed to the rear end of the cup-picking seat 231. The first cup-picking arm 232 is located directly below the limiting space. The cup-picking robot 235 is used to send the cup that falls from the relief groove 236 to the cup-placing platform 21.

[0041] The specific process of retrieving the cup is as follows: The top edge of the bottom cup among the stacked cups is pressed onto the first cup-retrieving arm 232. When the cup-retrieving cylinder 234 drives the cup-retrieving seat 231 to move backward, the top edge of the bottom cup can fall onto the second cup-retrieving arm 233. Then, the cup-retrieving cylinder 234 drives the cup-retrieving seat 231 to move forward, allowing the top edge of the bottom cup to enter the gap between the first cup-retrieving arm 232 and the second cup-retrieving arm 233, and finally fall out of the second cup-retrieving arm 233 through the clearance groove 236. After being grasped by the cup-retrieving robot arm 235, it is placed on the cup-placement platform 21. At the same time, when the cup-retrieving cylinder 234 drives the cup-retrieving seat 231 to move forward, the cup located on the second to last layer can slide down onto the first cup-retrieving arm 232 under the guide at the front tip of the first cup-retrieving arm 232, thus completing one cup-retrieving process.

[0042] Preferably, the cup placement platform 21 is located directly below the second cup-retrieving arm 233. The cup-retrieving robot 235 includes a cup-retrieving clamping arm 2351, a cup-retrieving clamping cylinder 2352, and a vertical drive cylinder 2353. Both output ends of the cup-retrieving clamping cylinder 2352 are connected to the cup-retrieving clamping arm 2351 for clamping the cup. The vertical drive cylinder 2353 is connected to the frame 1, and the telescopic rod of the vertical drive cylinder 2353 is fixed to the cup-retrieving clamping cylinder 2352.

[0043] When the cup-retrieving robot 235 retrieves a cup, the cup-retrieving clamping cylinder 2352 can drive the two cup-retrieving clamping arms 2351 to retract and clamp the cup. Then, the vertical drive cylinder 2353 drives the cup-retrieving clamping cylinder 2352 to descend, so as to bring the cup down onto the cup-placement platform 21.

[0044] In this embodiment, the cup-moving mechanism 3 includes a cup-moving guide rail 31, a cup-moving slide 32, a cup-moving rotary cylinder 33, a cup-moving robot 34, and a cup-moving drive assembly. The cup-moving guide rail 31 is arranged along the length of the frame 1 on a wide side of the frame 1. The cup-moving slide 32 is connected to the cup-moving guide rail 31. The cup-moving rotary cylinder 33 is fixed to the cup-moving slide 32. The cup-moving robot 34 is connected to the cup-moving rotary cylinder 33. The cup-moving robot 34 is used to grasp the cup. The cup-moving drive assembly is used to drive the cup-moving robot 34 to move along the direction of the cup-moving guide rail 31.

[0045] When the cup transfer mechanism 3 is working, the cup transfer robot 34 can grab the cup from the cup placement platform 21. Then, the rotary cylinder drives the cup transfer robot 34 to rotate parallel to the length direction of the frame 1. Then, the cup transfer drive assembly drives the cup transfer robot 34 to move along the cup transfer guide rail 31, so that the cup transfer robot 34 can be sequentially brought to the color mixing mechanism 4, the stirring mechanism 5, and the cup dispensing mechanism 6, thereby completing the cup transportation and ensuring the automation process.

[0046] In this embodiment, the ingredient assembly 42 further includes an ingredient frame 425 and an ingredient drive 426. A plurality of color paste needle valves 421 and a plurality of thickener needle valves 422 are arranged on the ingredient frame 425. The discharge cylinder 423 is fixed to the frame 1 and located above the color paste needle valves 421 and thickener needle valves 422. The ingredient drive 426 drives the ingredient frame 425 to move along the length of the frame 1, allowing the handles of the color paste needle valves 421 and thickener needle valves 422 to pass through the grippers 424 one by one. Thus, the ingredient drive 426 controls the color paste needle valve 421 or thickener needle valve 422 that needs to be activated. Therefore, a single discharge cylinder 423 can control the switching of multiple needle valves, resulting in a more ingenious and practical design. Simultaneously, the cup is placed on an electronic scale, allowing for precise control of the color paste and thickener ratio, thereby ensuring the accuracy of the color paste mixing.

[0047] Preferably, the color mixing mechanism 4 further includes a valve cleaning assembly 43, which includes a first clean water box 431 and a second clean water box 432 for containing clean water, and a cleaning drive cylinder 433 for driving the first clean water box 431 and the second clean water box 432 to rise and fall. The first clean water box 431 is used to immerse the color paste needle valve 421, and the second clean water box 432 is used to immerse the thickener needle valve 422.

[0048] After the pigment needle valve 421 and thickener needle valve 422 have finished discharging, the dispensing drive unit 426 drives the dispensing frame to move above the valve cleaning assembly 43. Then, the cleaning drive cylinder 433 can drive the first clean water box 431 and the second clean water box 432 to rise, so that the lower parts of the pigment needle valve 421 and the thickener needle valve 422 are immersed in clean water. This can prevent the pigment at the outlet of the pigment needle valve 421 from solidifying and clogging, and also clean the outlet of the thickener needle valve 422.

[0049] In this embodiment, the stirring mechanism 5 includes a clamping cylinder 51, clamping arms 52, a stirring connecting seat 53, a stirrer 54, a viscosity meter 55, a lateral drive assembly 56, and a lifting drive assembly 57. The clamping cylinder 51 is mounted on the frame 1, and both output ends of the clamping cylinder 51 are connected to the clamping arms 52. The clamping cylinder 51 is used to drive the two clamping arms 52 to move closer to each other and clamp the cup. The stirring connecting seat 53 is located above the clamping cylinder 51, and the stirrer 54 and the viscosity meter 55 are respectively provided at both ends of the stirring connecting seat 53. The lateral drive assembly 56 and the lifting drive assembly 57 are both connected to the frame 1. The lateral drive assembly 56 is used to drive the stirring connecting seat 53 to move laterally, and the lifting drive assembly 57 is used to drive the stirring connecting seat 53 to rise and fall, thereby allowing the stirrer 54 or the viscosity meter 55 to extend into the cup.

[0050] The specific operation of the stirring mechanism 5 is as follows: the clamping cylinder 51 drives the two clamping arms 52 to clamp the cup. Then, through the operation of the horizontal drive component 56 and the lifting drive component 57, the stirrer 54 can be inserted into the cup to stir and mix. The viscosity meter 55 can also be inserted into the cup to detect the viscosity of the liquid inside the cup. It should be noted that the horizontal drive component 56 and the lifting drive component 57 are existing devices that can be made using cylinders or linear modules.

[0051] In this embodiment, a cleaning mechanism 7 is also included. The cleaning mechanism 7 includes a cleaning box 71 and a cleaning mixer 72, both of which are mounted on the frame 1. The cleaning mixer 72 is located above the cleaning box 71 and extends into the cleaning box 71. Two mixing mechanisms 5 are provided, and the two mixing mechanisms 5 are symmetrically arranged on both sides of the cleaning box 71. The viscosity meter 55 of the mixing mechanism 5 is located at one end of the mixing connection seat 53 near the cleaning box 71.

[0052] After the viscosity meter 55 of the stirring mechanism 5 is used for testing, it needs to be cleaned to prevent it from affecting subsequent testing. Therefore, a cleaning mechanism 7 is set up for cleaning. The horizontal drive component 56 and the lifting drive component 57 can drive the viscosity meter 55 into the cleaning box 71. Then the cleaning stirrer 72 can stir in the cleaning box 71 to form a vortex, thereby rinsing the viscosity meter 55 clean.

[0053] Preferably, the cleaning mechanism 7 further includes a stirring and cleaning box 73 disposed on the frame 1, into which the stirrer 54 extends and performs cleaning.

[0054] In this embodiment, the cup dispensing mechanism 6 includes a conveyor belt conveying assembly 61. One end of the conveyor belt conveying assembly 61 extends into the frame 1 and is close to the stirring mechanism 5, while the other end of the conveyor belt conveying assembly 61 extends out of the frame 1, thereby conveying the cup containing the finished color paste out of the frame 1 for the user to pick up.

[0055] Preferably, the cup dispensing mechanism 6 further includes a V-shaped baffle 62 located at the conveying end of the conveyor belt assembly 61, which can stably stop the cup at the conveying end of the conveyor belt assembly 61.

[0056] In summary, compared with the existing technology, the fully automatic high-precision color paste sample preparation device of this application integrates multiple mechanisms to form an automated operation of color paste preparation, which can greatly reduce labor costs, make color paste preparation easier, increase work efficiency, and improve practicality.

[0057] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
