Description

Technical Field

[0001] This utility model relates to the field of quantitative ink filling, and in particular to a drip-proof quantitative ink bottle filling head mechanism. Background Technology

[0002] The ink bottle quantitative filling head mechanism is a core component used in the ink production and packaging field. It is installed on filling equipment to accurately deliver a preset volume of ink into the ink bottle and realize the automated control of the filling process. It mainly consists of a support structure, a feeding component, a quantitative control component, and an execution component. It can be adapted to batch filling operations of ink bottles of different specifications to ensure the consistency and efficiency of ink filling.

[0003] In the existing technology, the usage process and operation steps of the ink bottle quantitative filling head mechanism are as follows: Before use, the filling head mechanism is first debugged, the ink capacity for a single filling is set, and the connection and sealing between the filling head and the supply pipeline are checked to ensure that there is no looseness or leakage; then, the empty ink bottles to be filled are placed one by one on the support platform directly below the filling head through the conveyor line or manually, and the height of the support platform is adjusted so that the ink bottle mouth is aligned with the filling head outlet; after the equipment is started, the supply system delivers ink to the filling head, and the filling head injects a quantitative amount of ink into the bottle according to the preset parameters. After filling is completed, the support platform drives the ink bottle to descend and leave the filling head area, and then the ink bottle filled with ink is conveyed to the next process through the conveyor line. At the same time, a new empty ink bottle is moved to the filling position, and the above process is repeated to achieve continuous filling.

[0004] In actual use, existing ink bottle quantitative filling head mechanisms often leave a small amount of ink residue at the filling head outlet after filling is completed and the ink bottle is separated from the filling head. This residual ink will drip onto the support platform, the outer wall of the ink bottle, or the conveyor line due to gravity, requiring an additional cleaning process. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drip-proof ink bottle quantitative filling head mechanism, which aims to solve the problem that a small amount of ink is easily left at the outlet of the filling head in the prior art, and this residual ink will drip onto the support platform, the outer wall of the ink bottle or the conveyor line due to gravity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drip-proof ink bottle quantitative filling head mechanism, including a bracket A, a filling machine fixedly connected to the top of the bracket A, an electric cylinder fixedly connected to the top of the filling machine, a placement plate provided on the top of the electric cylinder, a filling head fixedly connected to the bottom of the filling machine, and a material suction mechanism provided on the outside of the filling head. The suction mechanism includes a bracket B, the outer wall of which is fixedly connected to the outer wall of the filling machine. A horizontal plate is rotatably connected to the outer wall of the bracket B. A support plate is fixedly connected to the outer wall of the filling head. A suction syringe is fixedly connected to the outer wall of the support plate. A piston rod is slidably connected to the inner wall of the suction syringe. A connecting ring is fixedly connected to the top of the piston rod. The outer wall of the connecting ring is slidably connected to the outer wall of the filling head.

[0007] As a further description of the above technical solution: a connecting rod B is hinged to the inner wall of the horizontal plate, and the top of the connecting rod B is fixedly connected to the bottom of the connecting ring.

[0008] As a further description of the above technical solution: a spring is fixedly connected to the outer wall of the connecting ring, and the extension end of the spring is fixedly connected to the outer wall of the bracket B.

[0009] As a further description of the above technical solution: a connecting rod C is fixedly connected to the outer wall of the horizontal plate, and the connecting rod C is located at the left extension end of the horizontal plate.

[0010] As a further description of the above technical solution: a one-way valve is fixedly connected to the outer wall of the suction syringe, and the other end of the one-way valve is fixedly connected to the outer wall of the filling head.

[0011] As a further description of the above technical solution: an ink bottle is provided on the top of the placement plate, and the ink bottle is located at the bottom of the filling head.

[0012] As a further description of the above technical solution: the number of suction syringes is two sets, and the two sets of suction syringes are symmetrically arranged at equal intervals at both ends of the outer wall of the filling head.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the air in the suction syringe is discharged by the piston rod of the horizontal plate when the ink bottle rises. When it falls, the spring returns and pulls the piston rod to generate negative pressure in the suction syringe, which accurately sucks up the residual ink in the filling head. At the same time, the two sets of symmetrical suction syringes move synchronously to improve the uniformity of suction. The one-way valve ensures that the ink flows in one direction and avoids backflow.

[0014] 2. In this utility model, the recycled residual ink can be pushed back to the filling head for reuse, which greatly reduces ink waste and lowers production costs. Moreover, the whole adopts a mechanical linkage structure that does not require additional power, taking into account both ease of operation and low energy consumption, and can be adapted to continuous quantitative filling operations.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a drip-proof ink bottle quantitative filling head mechanism, including a support A1, which provides basic support for the overall device. A filling machine 2 is fixedly connected to the top of the support A1, providing power for quantitative ink delivery. An electric cylinder 7 is fixedly connected to the top of the filling machine 2, driving a placement plate 5 to move up and down. The placement plate 5 is located on the top of the electric cylinder 7, supporting and synchronously moving the ink bottle 6. A filling head 3 is fixedly connected to the bottom of the filling machine 2, serving as the ink output channel. The filling head 3 is externally equipped with a suction mechanism 4, which is used to absorb residual ink in the filling head 3 to prevent dripping. The suction mechanism 4 includes a bracket B411, which provides a rotational support point for the horizontal plate 412. The outer wall of the bracket B411 is fixedly connected to the outer wall of the filling machine 2. The horizontal plate 412 is rotatably connected to the outer wall of the bracket B411. The horizontal plate 412 can rotate around the bracket B411 and is linked to the connecting rod B4111. The outer wall of the filling head 3 is fixedly connected to a support plate 416, which is used to fix the suction syringe 417. The outer wall of the support plate 416 is fixedly connected to... There is a suction syringe 417, which achieves suction and discharge action by sliding a piston rod 4112. The piston rod 4112 is slidably connected to the inner wall of the suction syringe 417. The movement of the piston rod 4112 can change the internal air pressure of the suction syringe 417. A connecting ring 415 is fixedly connected to the top of the piston rod 4112. The connecting ring 415 can drive the piston rod 4112 to slide along the filling head 3. The outer wall of the connecting ring 415 is slidably connected to the outer wall of the filling head 3. The connecting ring 415 is used to transmit the force of the connecting rod B 4111 to the piston rod 4112. The inner wall of the horizontal plate 412 is hinged. A connecting rod B4111 is connected to the horizontal plate 412. The top of the connecting rod B4111 is fixedly connected to the bottom of the connecting ring 415. A spring 414 is fixedly connected to the outer wall of the connecting rod C4113. The spring 414 provides a restoring force for the horizontal plate 412. The extended end of the spring 414 is fixedly connected to the outer wall of the bracket B411. The connecting rod B4111 is fixedly connected to the outer wall of the horizontal plate 412. The connecting rod B4111 is used to connect the horizontal plate 412 and the spring 414. The connecting rod C4113 is located at the left extended end of the horizontal plate 412.

[0019] Reference Figures 1-3A one-way valve 418 is fixedly connected to the outer wall of the suction syringe 417. The one-way valve 418 controls the ink to flow into the suction syringe 417 in only one direction. The other end of the one-way valve 418 is fixedly connected to the outer wall of the filling head 3. The one-way valve 418 realizes the communication between the filling head 3 and the suction syringe 417. An ink bottle 6 is set on the top of the placement plate 5. The ink bottle 6 is used to receive a quantitative amount of ink. The ink bottle 6 is located at the bottom of the filling head 3. When the ink bottle 6 rises, it can push the horizontal plate 412. There are two sets of suction syringes 417. The two sets of suction syringes 417 improve the suction stability. The two sets of suction syringes 417 are symmetrically arranged at both ends of the outer wall of the filling head 3 at equal intervals. The two sets of suction syringes 417 move synchronously to ensure uniform suction. This device achieves drip-proof quantitative filling through the coordinated action of the suction mechanism 4 and the electric cylinder 7. The electric cylinder 7 drives the placement plate 5 to rise and fall, providing power for the lifting action. The placement plate 5 drives the ink bottle 6 to rise synchronously, forming a linkage structure between the placement plate 5 and the ink bottle 6. During the rise of the ink bottle 6, it pushes the horizontal plate 412. The ink bottle 6 drives the horizontal plate 412 to rotate through the lifting force. The horizontal plate 412 rotates around the bracket B411 and drives the connecting ring 415 connected at the top to move downward through the connecting rod B4111 at the bottom hinge. The horizontal plate 412 converts the lifting force into the sliding force of the connecting ring 415. The connecting ring 415 then drives the piston rod 4112 to press downward. The connecting ring 415, in conjunction with the piston rod 4112, changes the internal space of the suction syringe 417, expelling the air in the suction syringe 417. The air expulsion from the suction syringe 417 prepares for subsequent negative pressure suction. At this time, the filling head 3... Ink is metered into ink bottle 6, and filling head 3 accurately outputs the preset amount of ink. After filling is completed, electric cylinder 7 drives placement plate 5 to lower ink bottle 6. Electric cylinder 7 reverses its action to remove ink bottle 6 from the working position. After ink bottle 6 is removed from horizontal plate 412, ink bottle 6 no longer exerts a pushing force on horizontal plate 412. Spring 414 generates a restoring force to pull horizontal plate 412 back to its initial position. The restoring force of spring 414 drives horizontal plate 412 to rotate in the opposite direction. Horizontal plate 412 pulls connecting ring 415 and piston rod 4112 upward through connecting rod B4111. Horizontal plate 412 transmits the restoring force to piston rod 4112, creating a negative pressure inside suction syringe 417. The negative pressure state of suction syringe 417 generates suction, which then draws in residual ink at the bottom of filling head 3 through one-way valve 418. One-way valve 418 guides the residual ink into suction syringe 417, effectively preventing ink dripping and achieving anti-drip function.

[0020] Working principle: This device achieves drip-proof quantitative filling by means of the synergistic action of the suction mechanism 4 and the electric cylinder 7. The electric cylinder 7 drives the placement plate 5 to rise and fall, and the placement plate 5 drives the ink bottle 6 to rise synchronously. During the rise of the ink bottle 6, it pushes the horizontal plate 412. The horizontal plate 412 rotates around the bracket B411 and drives the connecting ring 415 connected at the top to move downward through the connecting rod B4111 at the bottom hinge. The connecting ring 415 then drives the piston rod 4112 to squeeze downward, expelling the air in the suction syringe 417, preparing for subsequent suction. At this time, the filling head 3 delivers ink quantitatively into the ink bottle 6. After filling is completed, the electric cylinder 7 drives the placement plate 5 to lower the ink bottle 6. After the ink bottle 6 is separated from the horizontal plate 412, the spring 414 generates a reset force to pull the horizontal plate 412 back to its initial position. The horizontal plate 412 pulls the connecting ring 415 and the piston rod 4112 upward through the connecting rod B4111, so that a negative pressure is formed inside the suction syringe 417. Then, the ink remaining at the bottom of the filling head 3 is sucked in through the one-way valve 418, effectively preventing ink dripping and realizing the anti-drip function.
