Description

Technical Field

[0001] This invention relates to the field of automatic packaging equipment technology, and in particular to a fully automatic filling and pressing integrated machine. Background Technology

[0002] Paint is a viscous liquid applied to the surface of an object to be protected or decorated, forming a firmly adhering continuous film. It is typically based on resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, prepared using organic solvents or water. Current paint filling methods involve feeding the mixed paint into a tank, then dispensing the paint from the tank into conveyed filling containers, and finally transporting the containers to a capping area for capping. A similar structure is found in Chinese utility model patent CN 218055874 U, which requires manually placing the cap onto the filled container and then manually pressing down with a tool to achieve capping. Clearly, this type of structure cannot meet production capacity requirements. With the rapid development of automated production, processes such as cap feeding and capping can be automated. However, the integrated machine is bulky and cannot be used in workshops with limited space. For small workshops, only separate packaging machines for filling and capping can be used. Such packaging methods result in a lot of time being wasted on turnaround and have limited effect on improving overall packaging efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic filling and capping integrated machine that integrates automatic filling, capping and capping functions into one unit. The layout is more reasonable, the whole machine is miniaturized, and the filling production efficiency is improved while being able to adapt to production workshops of more sizes.

[0004] The technical solution to achieve the objective of this invention is:

[0005] A fully automatic filling and pressing integrated machine includes a conveying unit and a filling unit, a top cover unit, and a pressing unit arranged sequentially along the conveying direction on the side of the conveying unit. The conveying unit is used to convey filling barrels to other workstations for filling production. Weighing units are installed on the conveying unit directly below the filling unit and between the top cover unit and the pressing unit. The two weighing units are used for filling weighing and filling re-inspection, respectively. The top cover unit includes an inclined cover bin and a cover feeding unit located at the lower end of the cover bin. The cover bin is used to place stacked barrel caps and feed the barrel caps one by one to the lower end of the cover bin. The cover feeding unit transfers the barrel caps at the lower end of the cover bin to the top of the conveyed filling barrels by flipping. The pressing unit is adapted to press down on the barrel caps to fasten them onto the filling barrels.

[0006] Furthermore, the conveying unit includes a chain conveyor and a guardrail section disposed on the conveying plane of the chain conveyor. The guardrail section includes a fixedly disposed first handwheel screw assembly and a first guardrail disposed opposite to each other. The spacing between the two first guardrails is adjusted by the first handwheel screw assembly to meet the requirements for linear conveying of filling barrels of different specifications.

[0007] Furthermore, the chain conveyor is detachably equipped with equally spaced positioning blocks on its conveying surface, thereby separating adjacent filling barrels and improving the conveying position accuracy of the filling barrels.

[0008] Furthermore, the weighing surface of the weighing unit is provided with a slot aligned with the positioning block, and the slot extends through the weighing surface along the conveying direction.

[0009] Furthermore, the filling unit includes a first frame and a material box, a feeding section, and a piston section fixedly installed on the first frame.

[0010] Furthermore, the second chamber is located below the first chamber. The switching mechanism includes a switching cylinder fixedly installed on the top of the first chamber. The piston rod of the switching cylinder is coaxially fixedly connected to a guide rod that is sealed and inserted into the first chamber.

[0015] Furthermore, a second clamping mechanism is provided above the first clamping mechanism along the inclined direction.

[0016] Furthermore, it also includes a second guardrail arranged opposite to each other and a third guardrail located between the two guardrails. The side and bottom of the material rack are respectively equipped with a second lead screw adjustment assembly and a third lead screw adjustment assembly. The two second guardrails are installed parallel to each other on the material rack through the second lead screw adjustment assembly, and the third guardrail is arranged parallel to the second guardrails and is installed on the material rack in an adjustable manner along the direction perpendicular to the plane of the material rack through the third lead screw adjustment assembly.

[0017] Furthermore, a mounting base is fixedly provided at the bottom of the second guardrail, and an intermediate plate is adjustablely provided on the mounting base along the length direction of the second guardrail. The first cover clamping mechanism includes a first cover clamping cylinder respectively fixedly mounted on the two intermediate plates. The piston rod of the first cover clamping cylinder is positioned toward the stacked bucket lids and is fixedly connected to a clamping plate. The clamping plate has an arc-shaped notch on the side facing the bucket lid. The cover dragging mechanism includes a cover dragging cylinder respectively fixedly mounted on the two mounting bases. The piston rod of the cover dragging cylinder is positioned toward the stacked bucket lids and is fixedly connected to a support plate.

[0018] Furthermore, the second guardrail has a plurality of mounting holes along its length near its lower end, and the second cover clamping mechanism includes a second cover clamping cylinder that is adjustablely mounted on the second guardrail by bolts and mounting holes. The piston rod of the second cover clamping cylinder is positioned away from the stacked barrel covers and is fixedly connected to a clamping block, which extends to the upper cover channel.

[0019] Furthermore, the cover feeding part includes a connecting plate and a rotating shaft that are fixedly and rotatably installed at the lower end of the material rack. The end of the connecting plate is inclined upward along the opposite direction of conveying and a sliding block is rotatably installed thereon. A linear guide rail is fitted on the sliding block. A flipping frame is fixedly installed on the rotating shaft. The other side of the flipping frame is fixedly connected to the linear guide rail and a cover suction part is fixedly installed thereon. A flipping cylinder is hinged on the material rack. The piston rod of the flipping cylinder is hinged to a connecting rod. The connecting rod is parallel to the connecting plate and fixedly connected to the rotating shaft.

[0020] Furthermore, the capping section includes a second frame on which a capping cylinder is fixedly mounted. The piston rod of the capping cylinder is vertically downward and detachably fixed to a pressure head, which is located directly above the conveying section.

[0021] Furthermore, it also includes a lifting platform, which is fixedly installed on the side of the conveying section, and the filling section, the top cover section and the capping section are all installed on the lifting platform.

[0022] Furthermore, it also includes a housing, in which the conveying section, filling section, top cover section and capping section are all located. The top of the housing has a notch corresponding to the filling section and the top cover section, and the sides have windows facing the inlet and outlet of the conveying section, respectively.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects:

[0024] This invention integrates the filling section, capping section, and crimping section sequentially along the conveying direction on the side of the conveying section, achieving multiple functions in one unit. It also features two weighing sections: one weighs the paint being filled, enabling automatic filling and weighing, while the other performs a re-inspection before crimping to ensure the paint weight in the container meets the standard, thus avoiding rework due to unqualified weight after crimping. The capping section consists of an inclined cap chamber and a flip-up cap delivery section, achieving automatic cap delivery while saving capping space. The overall layout is more reasonable, realizing the miniaturization of the entire machine and improving filling production efficiency while adapting to production workshops of various sizes.

[0025] This invention cleverly designs the structure of the feeding section and uses a switching mechanism to create two different channels. Compared to traditional pipeline structures, the channel size is significantly increased. The piston section achieves very high material extraction and discharge speeds, thereby improving the filling speed and enhancing overall filling efficiency without the need for multiple filling heads.

[0026] This invention utilizes a switching cylinder to drive two plugging blocks on a guide rod to rise and fall synchronously. By designing the channels between the two plugging blocks and the two chambers, as well as the relative positions of the outlet of the feeding section, it is possible to achieve outlet sealing, channel opening, piston suction feeding, outlet opening, channel sealing, piston push-out discharge. The structure is simple and easy to control.

[0027] This invention uses a servo motor lead screw module to drive the piston rod of the piston cylinder to reciprocate, thereby improving the movement accuracy of the piston rod and ensuring the accuracy of material suction, facilitating the control of filling accuracy. The feeding and discharging speeds can be adjusted by adjusting the size of the piston cylinder body.

[0028] The size of the cover channel of this invention is adjustable to meet the conveying requirements of bucket lids of different sizes. The stacked bucket lids are supported by the cover dragging mechanism, and the previous bucket lid is clamped by the first cover clamping mechanism. When the cover dragging mechanism is opened, the bucket lids naturally flow to the cover delivery part, realizing the one-by-one cover application.

[0029] The present invention adds a second clamping mechanism, which clamps the bucket lid to share part of the weight, thereby avoiding the large weight caused by a large number of stacked bucket lids. The first clamping mechanism is limited by the size of the bucket lid and has a thin clamping opening, which cannot clamp it, thus improving the stability of lid delivery.

[0030] This invention uses a cylinder-driven connecting rod to rotate a flipping frame, thereby flipping a cap-suction mechanism mounted on the flipping frame to transfer the cap at the end of the upper cap to the filling barrel below. The ingenious structural design requires only one cylinder to achieve the cap feeding action, enabling high-speed cap picking and placing and improving production efficiency.

[0031] The capping section of this invention uses a capping cylinder to drive the pressure head to rise and fall, thereby achieving automatic capping. The structure and action are rapid. The pressure head and the capping cylinder are detachably connected. By replacing the pressure head with different sizes, it can meet the needs of different sizes of bucket caps, thus improving versatility.

[0032] This invention enables the synchronous lifting of the conveying section, filling section, top cover section, and capping section by setting up a lifting platform, which can adapt to the filling needs of filling heads of different heights and improve production changeover efficiency.

[0033] This invention improves the safety of equipment use by enclosing the functional components in a chassis. Attached Figure Description

Detailed Implementation

[0042] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0043] (Example 1)

[0044] like Figures 1 to 5 The fully automatic filling and pressing machine shown includes a conveying unit 1, a filling unit 2, a capping unit 3, a pressing unit, and a weighing unit 5. The filling unit 2, the capping unit 3, and the pressing unit are arranged sequentially along the conveying direction on the side of the conveying unit 1, forming a filling station, a capping station, and a pressing station. The conveying unit 1 transports the filling barrels to each station for automatic filling production. There are two weighing units 5, installed on the conveying unit 1, located directly below the filling unit 2 and between the capping unit 3 and the pressing unit, respectively. The two weighing units are used for filling weighing and filling re-inspection, respectively. The capping unit 3 includes an inclined cap bin and a cap feeding unit located at the lower end of the cap bin. The cap bin is used to place stacked barrel caps and feed the barrel caps one by one to the lower end of the cap bin. The cap feeding unit transfers the barrel caps at the lower end of the cap bin to the top of the conveyed filling barrel through a flipping action, and then the pressing unit presses down the barrel cap to fasten it onto the filling barrel. The overall structure is compact and the layout is more reasonable, realizing the miniaturization of the whole machine and integrating filling and rolling functions into one, improving filling production efficiency while adapting to production workshops of more sizes.

[0045] Specifically, in order to improve the safety of filling production, this embodiment is provided with a machine box 6, in which the conveying part 1, the filling part 2, the top cover part 3 and the capping part are all located. The top of the machine box 6 is provided with notches corresponding to the filling part 2 and the top cover part 3, and the side is provided with windows facing the inlet and outlet of the conveying part 1 respectively.

[0046] The conveying unit 1 includes a chain conveyor 1-1 and a guardrail unit 1-2 disposed on the conveying plane of the chain conveyor 1-1. The guardrail unit 1-2 includes a fixedly disposed first handwheel screw assembly 1-2-1 and a first guardrail 1-2-2 disposed opposite to it. The spacing between the two first guardrails 1-2-2 is adjusted by the first handwheel screw assembly 1-2-1 to meet the requirements of linear conveying of filling barrels of different sizes. Positioning blocks 1-2-3 are detachably installed at equal intervals on the conveying surface of the chain conveyor 1-1 by screws, thereby separating adjacent filling barrels and improving the conveying position accuracy of the filling barrels. Meanwhile, the weighing surface of the weighing unit 5 has slots aligned with the positioning blocks 1-2-3, and the slots extend through the weighing surface along the conveying direction, ensuring that the positioning blocks do not interfere with the weighing unit 5 when moving with the chain conveyor 1-1.

[0047] In order to enable rapid production changeover for filling barrels of different heights, this embodiment has a lifting platform 7 fixedly installed on the side of the conveying section 1. The filling section 2, the top cover section 3 and the capping section are all installed on the lifting platform 7 to achieve synchronous lifting and adjustment, thereby improving the switching efficiency during production changeover without the need for repeated adjustments.

[0048] The filling unit 2 has a small material section 8 installed on the side of the conveying unit 1 at the front end of the conveying section 1. The small material section 8 is also fixedly mounted on the lifting platform 7 and is used to add various additives before filling. The filling unit 2 includes a first frame 2-1, a material box 2-2, a feeding section 2-3, and a piston section 2-4. The first frame 2-1 is fixedly mounted on the lifting platform 7, and the material box 2-2, the feeding section 2-3, and the piston section 2-4 are all fixedly mounted on the first frame 2-1. The feeding section 2-3 has a first chamber 2-3-1, a second chamber 2-3-2, and a switching mechanism. The switching mechanism includes a switching cylinder 2-3-3, a guide rod 2-3-4, a first leak-stopping block 2-3-5, and a second leak-stopping block 2-3-6. The material bin 2-2 is used to store paint. The first chamber 2-3-1 is connected to the material bin 2-2. The second chamber 2-3-2 is located below the first chamber 2-3-1 and its outlet faces the conveying part. The switching cylinder 2-3-3 is fixedly installed on the top of the first chamber 2-3-1. The piston rod is coaxially fixedly connected to the guide rod 2-3-4, which is sealed and inserted in the first chamber. The lower end of the guide rod 2-3-4 extends to the second chamber 2-3-2. The first plugging block 2-3-5 and the second plugging block 2-3-6 are coaxially fixedly installed on the guide rod 2-3-4 from top to bottom.

[0049] The piston unit 2-4 includes a piston cylinder 2-4-1 and a servo motor screw module 2-4-2, which are fixedly mounted on the first frame 2-1. The cylinder body of the piston cylinder 2-4-1 is directly connected to the side wall of the second chamber 2-3-2 and communicates with the inner cavity. The piston rod is fixedly connected to the moving block of the servo motor screw module 2-4-2. The piston rod of the piston cylinder is driven to reciprocate through the servo motor screw module 2-4-2, thereby improving the movement accuracy of the piston rod and ensuring the accuracy of material suction. This facilitates the control of filling accuracy. By selecting a piston cylinder with a larger cylinder body, the feeding and discharging speeds are increased, thereby improving efficiency.

[0050] When the switching mechanism is in the first state, the first plugging block 2-3-5 is located in the second chamber 2-3-2, and the second plugging block 2-3-6 blocks the outlet of the second chamber 2-3-2, forming a sealed space between the material bin 2-2, the first chamber 2-3-1, and the second chamber 2-3-2. The paint in the material bin 2-2 is rapidly drawn into the discharge section by the piston of the piston cylinder 2-4-1. When the switching mechanism is in the second state, the first plugging block 2-3-5 is located at the connection between the first chamber 2-3-1 and the second chamber 2-3-2, separating the two chambers. The second plugging block 2-3-6 is located above the outlet of the second chamber 2-3-1, and is pushed out by the piston of the piston cylinder 2-4-1, allowing the paint in the second chamber and the piston cylinder to be rapidly injected into the filling barrel. A single cylinder completes the three-way switching, and the passage is very large, enabling very high suction and discharge speeds, significantly improving the filling speed.

[0051] Considering the irritating odor of the paint itself, this embodiment has a baffle 2-5 fixedly connected to the bottom of the feeding section 2-3, which is suitable for covering the mouth of the filling barrel. The baffle 2-5 is provided with a suction port 2-5-1 located in the mouth area. The suction port is connected to an external negative pressure filtration system through a pipe. During filling, the odor generated during paint filling can be purified, and the workshop environment can be kept comfortable.

[0052] The cover section includes a material rack 3-1 inclined upwards along the conveying direction. The material rack 3-1 has an adjustable cover channel to accommodate bucket lids of different sizes. Specifically, the cover channel consists of two opposing second guardrails 3-2 and a third guardrail 3-3 parallel to each other between the two guardrails. A second screw adjustment assembly 3-4 and a third screw adjustment assembly 3-5 are respectively installed on the side and bottom of the material rack 3-1. The two second guardrails 3-2 are installed parallel to each other on the material rack 3-1 with adjustable spacing via the second screw adjustment assembly 3-4. The third guardrail is installed on the material rack 3-1 with adjustable spacing along the plane perpendicular to the material rack via the third screw adjustment assembly 3-5. A lid-separating mechanism is provided at the lower end of the cover channel. The lid-separating mechanism includes a first lid-clamping mechanism 3-6 and a lid-dragging mechanism 3-7 aligned from top to bottom along the inclined direction of the material rack 3-1. The first lid-clamping mechanism 3-6 and the lid-dragging mechanism 3-7 are used to clamp and drag the bucket lids located in the second-to-last and last positions, respectively. Specifically, the bottom of the second guardrail 3-2 is fixedly provided with a mounting base 3-8, and an intermediate plate 3-9 is adjustablely provided on the mounting base 3-8 along the length of the second guardrail 3-2. The first cover clamping mechanism 3-6 includes a first cover clamping cylinder 3-6-1 respectively fixedly mounted on the two intermediate plates 3-9. The piston rod of the first cover clamping cylinder 3-6-1 is positioned towards the stacked bucket lids and is fixedly connected to a clamping plate 3-6-2. The clamping plate 3-6-2 has an arc-shaped notch on the side facing the bucket lid to increase the contact area with the bucket lid. The cover dragging mechanism 3-7 includes a cover dragging cylinder 3-7-1 respectively fixedly mounted on the two mounting bases 3-8. The piston rod of the cover dragging cylinder 3-7-1 is positioned towards the stacked bucket lids and is fixedly connected to a support plate 3-7-2. The end lid is held by the lid dragging mechanism 3-7, and the previous lid is clamped by the first lid clamping mechanism 3-6. When the lid dragging mechanism is opened, the lid is detached from the lid compartment and flows naturally to the lid delivery section, thus achieving lid application one by one.

[0053] Considering the large number of bucket lids and their substantial weight after stacking, and the relatively flat shape of the lids, the clamping plate 3-6-2 of the first clamping mechanism is too thin, resulting in insufficient clamping force. In this embodiment, a second clamping mechanism 3-10 is provided above the first clamping mechanism 3-6 along the inclined direction of the material rack. This clamps the bucket lids, sharing some of the weight and improving the stability of the lid feeding. Specifically, the second guardrail 3-2 has multiple mounting holes along its length near its lower end. The second clamping mechanism 3-10 includes a second clamping cylinder 3-10-1, adjustablely mounted on the second guardrail via bolts and mounting holes. The piston rod of the second clamping cylinder 3-10-1 is positioned away from the stacked bucket lids and is fixedly connected to a clamping block 3-10-2. The clamping block extends to the upper cover channel and is not limited by the thickness of the clamping plate 3-6-2, thus ensuring sufficient clamping force.

[0054] The cover feeding part includes a connecting plate 3-11 and a rotating shaft 3-12, which are fixedly and rotatably installed at the lower end of the material rack 3-1. The end of the connecting plate 3-11 is inclined upward along the opposite direction of conveying and a sliding block is rotatably installed. A linear guide rail 3-13 is fitted on the sliding block. A flipping frame 3-14 is fixedly installed on the rotating shaft 3-12. The other side of the flipping frame 3-14 is fixedly connected to the linear guide rail and a cover suction part 3-15 is fixedly installed. A flipping cylinder 3-16 is hinged to the side of the material rack 3-1. The piston rod of the flipping cylinder 3-16 is hinged to a connecting rod 3-17. The connecting rod 3-17 is parallel to the connecting plate and fixedly connected to the rotating shaft 3-12. The rotating shaft is driven by the connecting rod 3-17 driven by the flipping cylinder 3-16, which in turn drives the flipping frame 3-14 to flip, so that the cap suction part 3-15 is aligned with the bucket cap at the bottom of the cap compartment, thus suctioning the bucket cap. The flipping cylinder 3-16 then resets, so that the cap suction part 3-15 is aligned with the filling bucket on the conveying section, completing the automatic cap feeding. The structure is ingeniously designed, requiring only one cylinder to realize the cap feeding action, achieving high-speed cap picking and placing, and improving production efficiency.

[0055] The capping section includes a second frame 4-1 fixedly mounted on the lifting platform. A capping cylinder 4-2 is fixedly mounted on the second frame 4-1. The piston rod of the capping cylinder 4-2 is vertically downward and detachably fixedly connected to a pressure head 4-3. The pressure head 4-3 is located directly above the conveying section and presses the caps placed on the filling barrels to achieve automatic capping.

[0056] The workflow of this embodiment is as follows: The empty filling barrel is first driven by the conveyor to the bottom of the small material section 8 for small material filling, and then it reaches the filling section 2 for paint filling. At the same time, the weighing section works. When the weight reaches the set value, the filling stops, and the filling barrel continues to flow to the capping section 3 to complete the automatic capping. It is then re-inspected by another weighing section. Filling barrels with qualified weight are automatically capped in the capping section, while those that are not qualified are not capped to avoid destructive rework.

[0057] This invention integrates the filling section, capping section, and crimping section sequentially along the conveying direction on the side of the conveying section, achieving multiple functions in one unit. It also features two weighing sections: one weighs the paint being filled, enabling automatic filling and weighing, while the other performs a re-inspection before crimping to ensure the paint weight in the container meets the standard, thus avoiding rework due to unqualified weight after crimping. The capping section consists of an inclined cap chamber and a flip-up cap delivery section, achieving automatic cap delivery while saving capping space. The overall layout is more reasonable, realizing the miniaturization of the entire machine and improving filling production efficiency while adapting to production workshops of various sizes.

It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention.
