Description

Technical Field

[0001] This invention relates to the field of filling equipment technology, specifically a rotary 6-head pigment filling machine. Background Technology

[0002] Pigments are an indispensable coloring agent in painting. Pigments can be in powder form and are diluted with liquids such as water or oil before use. Most pigments are insoluble in water and oil, but can be dispersed in these media. For ease of use and accurate color matching, manufacturers often dilute pigments with a medium to make them liquid.

[0003] Pigment filling is a crucial step in the pigment production process. Currently, for multi-compartment pigment boxes, single-station sequential filling or manual-assisted filling methods are commonly used. These methods suffer from low production efficiency, high labor costs, inconsistent filling volumes across boxes, and poor coordination with subsequent processes such as capping and coding. In particular, the end caps of the pigment boxes are usually connected to the box body via a film, requiring pre-folding and final pressing before and after filling. Traditional equipment struggles to efficiently and reliably complete this series of actions. Therefore, there is an urgent need for an integrated device that can automate feeding, pre-folding caps, simultaneous filling, capping, coding, and unloading to improve production efficiency, ensure product quality, and reduce labor costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rotary 6-head pigment filling machine with high automation, high filling efficiency, and stable and reliable operation.

[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A rotary 6-head pigment filling machine includes a machine housing and a human-machine interface for automatic operation of the control equipment. The machine housing is equipped with an intermittently rotating rotary dividing mechanism, and the edge of the rotary table is provided with a fixture plate for placing pigment integrated boxes. Along the rotation direction of the rotary dividing mechanism, there are sequentially arranged a manual box placement station, a pre-folding cap mechanism, a six-head filling mechanism, a capping mechanism, a coding mechanism, and a feeding mechanism; the pre-folding cap mechanism is used to pre-fold the end caps of the pigment integrated boxes. First, the clamping component presses the pigment box body to make the end caps lift up, and then the pre-folding cap component pushes the end caps to pre-fold. The capping mechanism is used to put the end caps on. First, the clamping linkage group presses the pigment box body to make the end caps lift up. Then, the cap pushing component pushes the end caps onto the pigment box body, and finally, the cap pressing component presses the end caps on. The six-head filling mechanism can inject pigment into each box of the pigment box at one time. The coding mechanism codes the box with the end caps on. The unloading mechanism pushes the pigment box out of the fixture plate.

[0006] In summary, the system is structured along the rotation direction of the turntable dividing mechanism, consisting of a manual box placement station, a pre-folding cap mechanism, a six-head filling mechanism, a capping mechanism, a coding mechanism, and a feeding mechanism. During operation, the operator places the pigment boxes onto the fixture plate. The turntable dividing mechanism then transfers the pigment boxes to the pre-folding cap mechanism. The pre-folding cap mechanism's clamping components press the pigment box body, causing the end caps to tilt upwards. The pre-folding cap components push the end caps to pre-fold, preventing them from failing to be properly capped in subsequent processes. After the pre-folded end caps are inspected, they are conveyed to the six-head filling mechanism, which injects the pigment into each of the pigment boxes in one continuous filling process. After filling, the pigment boxes are conveyed to the capping mechanism. First, the clamping linkage on the capping mechanism presses the pigment box body, causing the end caps to lift. Then, the cap-pushing component pushes the end caps towards the pigment box body, and finally, the cap-pressing component presses the end caps tightly. After capping, the boxes are conveyed to the coding mechanism, which engraves the end caps of each pigment box. After coding, the boxes are conveyed to the unloading mechanism, which pushes the pigment-filled boxes off the fixture plate, allowing them to flow out of the equipment. This setup automates the entire production process of pigment boxes, from placement, pre-capping, filling, capping, coding to unloading, significantly improving production efficiency. Furthermore, since all processes are completed on the same equipment, manual intervention in intermediate steps is reduced, ensuring consistency in filling volume across boxes and improving product quality. The equipment also features a compact structure, small footprint, and stable and reliable operation, effectively reducing labor costs and meeting the needs of modern pigment production.

[0007] As a further improvement of the present invention, the jig plate has a receiving groove for accommodating the paint box body, and a stop bar extending along the receiving groove is provided on the end face of the jig plate. The paint box body and the end cap are connected and contact the stop bar. When the paint box body is pressed down and sinks into the receiving groove, it is blocked by the stop bar, causing the end cap to tilt upwards. The beneficial effect of this design is that, by utilizing the structure of the jig plate itself, the end cap can be reliably tilted upwards with the help of the stop bar through a simple pressing action, creating conditions for subsequent pre-folding or capping actions. The structure is ingenious and the action is stable.

[0008] As a further improvement of the present invention, the clamping component includes a fixed vertical rod and a clamping seat that can slide along the axial direction of the fixed vertical rod. The clamping seat is equipped with a first pressing cylinder whose output end moves toward the fixture plate, and the output end is equipped with a pressing box plate. The first pressing cylinder drives the pressing box plate to press down on the body of the pigment integrated box. Under the action of the downward pressure, the end cap is raised, and the pre-folding cap component cooperates to push the raised end cap to pre-fold. The beneficial effect of this design is that the clamping component is driven by a cylinder, and the downward pressure is uniform and controllable, ensuring that the box is stably pressed into the fixture groove, while making the end cap raising angle consistent, providing a precise initial position for the pre-folding cap action.

[0009] As a further improvement of the present invention, the pre-folding cap component includes an adjusting plate mounted on a fixed plate of the turntable dividing mechanism. The adjusting plate is equipped with a horizontally pushing cylinder whose output end moves towards the fixture plate, and the output end is provided with a T-shaped push plate. A first adjusting groove is provided at the connection between the T-shaped push plate and the output end, through which the height of the T-shaped push plate is adjusted. Second adjusting grooves are symmetrically provided at both ends of the adjusting plate, through which the front-to-back position of the adjusting plate is adjusted. The beneficial effects of this design are: the T-shaped push plate can act on the end caps of multiple integrated boxes simultaneously, achieving synchronous pre-folding. Through the first and second adjusting grooves, the height and front-to-back position of the push plate can be flexibly adjusted to adapt to different specifications of pigment integrated boxes, improving the versatility and debugging convenience of the equipment.

[0010] As a further improvement of the present invention, the six-head filling mechanism includes multiple pigment tanks containing different pigments, located at one end of the machine housing, and a filling pump connected to each pigment tank via pipelines. A support frame is provided on the fixed plate of the turntable dividing mechanism on the opposite side of the pigment tanks, and a lifting cylinder is provided on the front side of the support frame. The output end of the lifting cylinder is provided with a horizontal clamping plate, which clamps multiple injection needles connected to each filling pump via pipelines. Each injection needle corresponds to a pigment box. The beneficial effect of this design is that, through multiple independent pigment tanks and a filling pump system, combined with the synchronous injection of multiple needles driven by the lifting cylinder, the filling of six pigment boxes can be completed at one time, greatly improving the filling efficiency and ensuring the consistency of the filling actions at each station.

[0011] As a further improvement of the present invention, the clamping linkage assembly includes a second pressing cylinder. The output end of the second pressing cylinder is provided with a horizontal connecting plate, and the horizontal connecting plate is provided with multiple horizontal pressing rods. The second pressing cylinder is mounted on the capping component. The beneficial effects of this design are: before sealing, the second pressing cylinder drives the horizontal pressing rods to press down on the box body, causing the end cap to tilt back, ensuring that the end cap is in an easily openable state. The multiple pressing rods can apply force evenly, preventing the box body from shifting.

[0012] As a further improvement of the present invention, the capping component includes a support rod fixed to the chassis, a fixed seat on the back of the support rod, and a set of third pressing cylinders on the front side of the fixed seat. Each third pressing cylinder has a pressing plate at its output end, and an elastic pressing block is fixed to the bottom of the pressing plate. A second pressing cylinder is fixed to the front side of the fixed seat, and a connecting vertical plate connected to the set of third pressing cylinders is provided on the front side wall of the second pressing cylinder. The beneficial effect of this design is that after the capping component pushes the end cap to the closed position, the elastic pressing block driven by the set of third pressing cylinders performs final compaction of the end cap. The elastic pressing block can avoid damage to the product from rigid impacts, ensuring a tight seal. The integrated design of the clamping linkage assembly and the capping component results in a compact structure and smooth operation.

[0013] As a further improvement of the present invention, the push-cover component includes a front-push slide cylinder fixed to the back of the fixed plate of the turntable dividing mechanism. The output end of the front-push slide cylinder is provided with an L-shaped plate. The L-shaped plate has push grooves that match the shape of the end caps of each box in the pigment integrated box. A set of vertical grooves is opened on the side of the L-shaped plate connected to the front-push slide cylinder, through which the height of the L-shaped plate is adjusted. The beneficial effects of this design are: the front-push slide cylinder provides a smooth linear thrust; the push grooves on the L-shaped plate can accurately engage multiple raised end caps and simultaneously push them closed; the vertical groove design facilitates the adjustment of the L-shaped plate height, ensuring that the push grooves and end caps are aligned.

[0014] As a further improvement of the present invention, the coding mechanism includes a movable module fixed on a fixed plate of the turntable dividing mechanism and a coding module disposed at the moving end of the movable module. The advantages of this design are: the movable module can drive the coding module to accurately position itself, and the product is coded after the capping is completed, resulting in a high degree of automation and accurate marking position.

[0015] As a further improvement of the present invention, the unloading mechanism includes a fixed bracket fixed inside the machine housing, a horizontal rod fixed to the back of the fixed plate of the turntable dividing mechanism, and a discharge slide. The fixed bracket is equipped with a lifting cylinder whose output end passes through the machine housing and moves toward the fixture plate. Multiple push rods are arranged at the output end of the lifting cylinder. An adjustable-angle baffle is rotatably mounted at the end of the horizontal rod. The baffle is equipped with a rotating shaft rotatably connected to the horizontal rod, and the horizontal rod is equipped with a locking element for locking the rotating shaft. Driven by the lifting cylinder, the pigment box is pushed out of the fixture plate and blocked by the baffle, causing the pigment box to fall into the discharge slide. The advantages of this design are: the lifting cylinder, in conjunction with multiple push rods, smoothly pushes the product out of the fixture plate; the adjustable-angle baffle guides the product to accurately fall into the discharge slide, completing automated unloading. The baffle angle is adjustable to adapt to different discharge trajectory requirements.

[0016] In summary, the beneficial effects of this invention are:

[0017] 1. The turntable dividing mechanism enables intermittent circulating flow operation, integrating box placement, pre-capping, six-head synchronous filling, capping, coding, and unloading into one unit, achieving fully automated production and significantly reducing manual intervention. In particular, it completes six-color filling in one go, realizing full automation of the pigment box from placement to finished product unloading, with stable cycle time and greatly improving production efficiency.

[0018] 2. Both the pre-folding cap mechanism and the sealing cap mechanism adopt a two-step design: first, the body is pressed to make the cap tilt up, and then the end cap is operated. Combined with the baffle structure on the jig plate, the design cleverly utilizes the structural characteristics of the pigment box itself, making the opening, pre-folding and final pressing of the end cap smooth and reliable, thus ensuring the packaging quality.

[0019] 3. The six-head filling mechanism enables simultaneous filling in one go, resulting in high filling efficiency and good consistency in the filling volume of each box.

[0020] 4. The pre-folding cap component, the push-cap component, and the feeding baffle are all designed with adjustment grooves or rotating mechanisms, facilitating adjustments to the position, angle, and height according to different specifications of pigment cartridges, thus enhancing the equipment's versatility. The integrated coding and automatic feeding functions further reduce manual intervention and improve the automation level of the production line.

[0021] 5. The various mechanisms are rationally distributed around the turntable, resulting in a compact structure and space-saving design. The use of cylinders and slide cylinders as actuators ensures precise and rapid action. Combined with the precise indexing of the turntable divider, this guarantees the stability and continuity of the entire workflow. Attached Figure Description

[0028] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0029] The present invention provides the following preferred embodiments.

[0030] like Figure 1 and Figure 2 As shown, the rotary 6-head pigment filling machine provided by the present invention mainly includes a machine housing 1, a human-machine interface 2, a rotary table dividing mechanism 3, and various functional mechanisms arranged sequentially along the rotation direction of the rotary table; the machine housing 1 is provided with multiple waterproof elbow conduits 10 for wires and pipes to pass through.

[0031] In this embodiment, the turntable dividing mechanism 3 is used to transport the pigment integrated box to the local area of ​​each functional mechanism so that each functional mechanism can work. The turntable dividing mechanism 3 includes a divider and a motor that drives the divider to operate. A turntable 31 is provided on the output shaft of the driver, a fixed plate 32 is provided on the connecting flange of the driver, and multiple jig plates 4 are arranged on the circumferential edge of the turntable 31.

[0032] Each fixture plate 4 has a receiving groove 41 that matches the shape of the paint box body for positioning and placing the box. A stop bar 42 extending along the length of the receiving groove 41 is fixed on the end face of the fixture plate 4. When the paint box is placed in the receiving groove 41, the plastic connection between the box body and the end cap (the box body) fits precisely on the stop bar 42.

[0033] The manual box placement station is located at the starting position of the turntable. The operator places the empty paint box into the receiving slot 41 of the fixture plate 4.

[0034] The pre-folding cap mechanism 5 is located after the manual box placement station, and includes a pressing component 51 and a pre-folding cap component 52.

[0035] like Figure 3 As shown, its clamping component 51 includes a fixed vertical rod 511 fixed on the housing 1, and a clamping seat 512 is slidably fitted onto the fixed vertical rod 511 by a locking bolt to adjust the height. A first pressing cylinder 513 is installed on the clamping seat 512, with its output end facing downward and connected to a pressing box plate 514; a fixed vertical rod 511 located on the lower side of the clamping seat 512 is provided with a support plate 514 extending to the bottom of the turntable 31 and with a sensor for detecting the pigment box fixed at its end; when the pigment box is moved to the pre-folding cover mechanism 5, when the sensor detects the pigment box, the sensor feeds back a signal to the first pressing cylinder 513, causing the first pressing cylinder 513 to drive the pressing box plate 514 to move downward, so that the pressing box plate 514 presses down on the pigment box. When the pigment box is squeezed by the pressing box plate 514, the pigment box body is pressed down and sinks into the receiving groove 41, and the body is pushed by the stop rod 42, causing the end cover to tilt upward, so that the pre-folding cover component 52 can push the end cover.

[0036] The pre-folding cap component 52 includes an adjusting plate 521 mounted on a fixed plate 32 of the turntable dividing mechanism 3 via bolts passing through a second adjusting groove 523. A horizontal pushing cylinder 522 is mounted on the adjusting plate 521, and its output end is connected to a T-shaped push plate 524. The connection between the T-shaped push plate 524 and the cylinder rod is height-adjustable via bolts and a first adjusting groove 525. The horizontal pushing cylinder 522 drives the T-shaped push plate 524 to move towards the tilted end cap, causing the moving T-shaped push plate 524 to push the end cap to flip, thereby performing a flipping test on the end cap and ensuring the integrity of the pigment cartridge.

[0037] The six-head filling mechanism 6 is located after the pre-capping mechanism 5 and is used to inject pigment into each empty box of the pigment cartridge, such as... Figure 4 As shown, in this embodiment, the six-head filling mechanism 6 includes multiple pigment tanks 61, which are mounted at one end of the housing 1 via a fixing frame. The outlet of each pigment tank 61 is connected to a filling pump 62 via a pipeline. A support frame 63 is mounted on the fixing plate 32 of the turntable dividing mechanism 3, and a lifting cylinder 64 is mounted on its front side. The output end of the lifting cylinder 64 is connected to a horizontal clamping plate 65, on which six injection needles 66 are mounted. These injection needles 66 are connected to the outlets of the six filling pumps 62 via flexible hoses. The spacing between the six injection needles 66 is consistent with the spacing between the six boxes of the pigment integrated box. It should be noted that the horizontal clamping plate 65 has perforations arranged in a row, and the side of the horizontal clamping plate 65 has threaded holes corresponding to each perforation. Each threaded hole is connected to the corresponding perforation. The six injection needles 66 are inserted into the perforations respectively, and screws pass through the threaded holes so that the end of the screws presses against the injection needles 66, fixing the injection needles 66 in a vertical position on the horizontal clamping plate 65.

[0038] The capping mechanism 7 is located after the six-head filling mechanism 6 and is used to cover the end cap with the pigment cartridge body. For example... Figure 5 As shown, in this embodiment, the sealing mechanism 7 includes a pressing linkage assembly 71, a pushing component 72, and a pressing component 73. The pressing component 73 includes a support rod 731 fixed to the housing 1, with a fixed base 732 connected to the back of the support rod 731. Two third pressing cylinders 733 are mounted on the front side of the fixed base 732. The output end of each cylinder is connected to a pressing plate 734, and an elastic pressing block 735 (such as a silicone block or foam block) is adhered to the bottom of the pressing plate 734. The second pressing cylinder 711 of the pressing linkage assembly 71 is fixed to the front side of the fixed base 732, and its output end is connected downwards to a horizontal connecting plate 712. The side wall of the horizontal connecting plate 712 has five connecting holes, and a horizontal pressing rod 713 is fixed to each connecting hole. The front side wall of the second pressing cylinder 711 is fixedly connected to the cylinder bodies of the two third pressing cylinders 733 through a connecting vertical plate 714, making the three a single integrated structure. The push-cover component 72 includes a front push slide cylinder 721 fixed to the back of the fixed plate 32 by a bracket, and its output end is connected to an L-shaped plate 722. The L-shaped plate 722 has push grooves 723 that match the contours of the six end covers, and vertical grooves 724 on its side are used to adjust the installation height.

[0039] When sealing is required, the second pressing cylinder 711 drives the horizontal connecting plate 712 to move downward, causing the horizontal pressure rod 713 to press down on the connecting body between two adjacent paint boxes, so that the body of the paint box is inserted into the receiving groove 41, and the end cap is pushed up by the stop rod 42. At this time, the forward sliding cylinder 721 drives the L-shaped plate 722 to move towards the upturned end cap, so that the end cap is inserted into the push groove 723. When pushing forward, the end cap is folded towards the body of the paint box. When the setting position is moved, the forward sliding cylinder 721 stops driving. At this time, the two third pressing cylinders 733 synchronously drive the corresponding extrusion plates 734 to move downward, while the elastic pressure block 735 pushes the folded end cap to close with the body of the paint box.

[0040] A coding mechanism 8 is positioned after the sealing mechanism 7 and is used to print corresponding numbers on the end caps of each box (e.g., printing numbers 1, 2, 3, 4, 5, and 6 sequentially in the direction of movement). This coding mechanism 8 includes a moving module 81 (e.g., a linear moving module) mounted on a fixed plate 32, and a coding module 82 (e.g., a coding printer) mounted on the slider of the moving module 81. The printhead of the coding module 82 faces the product on the fixture plate 4. The moving module 81 drives the coding module 82 to move gradually, sequentially printing the corresponding numbers on the end caps of the respective boxes.

[0041] The feeding mechanism 9 is located after the inkjet printing mechanism 8 and is used to push the pigment cartridge out of the fixture plate 4. For example... Figure 6 As shown, in this embodiment, the feeding mechanism 9 includes a fixed bracket 91 fixed inside the machine housing 1, on which a lifting cylinder 92 is installed. The output rod of the lifting cylinder 92 passes vertically upward through the machine housing platform, and the end is fixed with three push rods 93 corresponding to the bottom of the pigment box. During operation, the lifting cylinder 92 drives the push rods 93 to rise, causing the push rods 93 to lift the pigment box located in the receiving groove 41 of the fixture plate 4, causing the pigment box to detach from the fixture plate 4 and fall onto the discharge slide 96, flowing out of the equipment through the discharge slide 96.

[0042] To ensure the smooth landing of the ejected pigment cartridges onto the discharge chute 96, a horizontal bar 94 is fixed to the back of the mounting plate 32. A rotating shaft 951 is rotatably connected to the end of the horizontal bar 94, and a baffle 95 is connected to the shaft 951. The shaft 951 is locked at an angle by locking screws. The discharge chute 96 is located below the baffle 95 and is fixed to the housing 1 by a connecting rod bracket. The ejected pigment cartridges are blocked by the inclined baffle 95, causing them to fall into the discharge chute 96 and flow out.

[0043] In summary, the working principle of this rotary 6-head pigment filling machine is as follows:

[0044] During operation, the turntable dividing mechanism 3 rotates intermittently according to a set rhythm. At the manual box placement station, the operator places the paint box into the fixture plate 4. The turntable 31 rotates, sending the box to the pre-folding cap station. The first pressing cylinder 513 drives the box pressing plate 514 to press down the box. As the box sinks, its connection with the end cap is blocked by the stop bar 42 on the fixture plate, forcing the end cap to tilt upwards. Subsequently, the horizontal pushing cylinder 522 drives the T-shaped push plate 524 to move forward, pushing the tilted end cap to a certain angle for pre-folding, in order to check whether the end cap and the paint box can be folded normally, preparing for the subsequent complete capping. This two-step design (pressing first and then pushing) avoids the possibility of breakage or inaccurate positioning caused by directly forcibly folding the cap, ensuring the smoothness and accuracy of the pre-folding action.

[0045] After pre-folding, turntable 31 delivers the workpiece to the six-head filling station. Lifting cylinder 64 drives the horizontal clamping plate 65 and its six injection needles 66 to descend, lowering the needles 66 to an appropriate height to prevent sprayed pigment from splashing and contaminating other cartridges or equipment. Six filling pumps 62 operate synchronously, precisely injecting pigment into the six cartridges through their respective pipelines and injection needles 66. Six-color filling is completed in one operation, increasing efficiency several times compared to single-head filling.

[0046] After filling, the workpiece enters the capping station. The second pressing cylinder 711 drives the horizontal pressure rod 713 downwards, pressing the box body again and causing the pre-folded end caps to tilt back to the appropriate angle. Next, the forward sliding cylinder 721 drives the L-shaped plate 722 forward, using the push groove 723 to push all the end caps together towards the box body. Then, two third pressing cylinders 733 simultaneously drive the extrusion plate 734 with elastic pressure blocks 735 downwards, completely flattening the end caps and pressing them tightly against the box body. The elastic pressure blocks 735 ensure even pressure distribution and do not damage the product surface. This capping process is smooth and the sealing is firm.

[0047] After sealing, the workpiece passes through the inkjet printing station. The moving module 81 drives the inkjet printing module 82 to move and print codes on the product surface. Finally, it reaches the unloading station, where the lifting cylinder 92 drives the push rod 93 to rise, lifting the finished product from the jig plate 4. The lifted product hits the angle-adjustable baffle 95, changes direction, and falls into the discharge chute 96, completing the automatic unloading. The entire cycle is performed automatically until all stations have completed their operations.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
