Description

Technical Field

[0001] The utility model relates to the field of packaging printing, in particular to an ink extrusion device. Background Art

[0002] Ink is an important material used in printing. It prints or sprays patterns and texts on substrates. Ink includes main ingredients and auxiliary ingredients, which are evenly mixed and repeatedly rolled to form a viscous colloidal fluid. With the acceleration of modern industrialization, the demand for ink production in various fields of manufacturing industry is gradually increasing, and the demand for different processing of ink is also gradually enriched.

[0003] In the process of filling and producing ink, an ink extrusion device is needed. A Chinese patent (publication number CN214525761 U) discloses an ink extrusion device for barreled ink, including a base, a lifting mechanism, a discharge pipe and a closing mechanism for closing the ink barrel body, wherein the closing mechanism includes a first piston plate and a connecting rod for closing the barrel mouth. This technical solution can conveniently take out the ink.

[0004] However, this technical solution still has defects. In the closed mechanism used for extrusion, the bottom of the first piston plate directly contacts the ink, which is very likely to produce ink residues. After the operation is completed, it is extremely complicated to clean the first piston plate. If there are ink residues that have not been fully cleaned, when new inks with different proportions are extruded, it is easy to produce a mixture of miscellaneous colors and miscellaneous materials, causing the produced ink to deviate from actual demand and reduce product quality. If the piston plate needs to be fully cleaned, the entire device needs to be disassembled and the piston plate needs to be fully cleaned. This process is time-consuming, labor-intensive, and unstable. First, it is necessary to propose a technical solution that is not prone to the above problems. Utility Model Content

[0006] In order to achieve the above purpose, an ink extrusion device is designed, including a vertical pole, a connecting arm sleeved on the vertical pole, a connecting plate connected to the connecting arm, and an electric hoist arranged on the top of the vertical pole, the electric hoist is connected to the connecting plate or the connecting arm, and is used to lift the connecting arm and the connecting plate.

[0007] An extrusion oil cylinder is provided on the top of the connecting plate, and the telescopic end of the extrusion oil cylinder passes through the connecting plate and is connected to the extrusion plate below the connecting plate, and the extrusion oil cylinder drives the extrusion plate to move up and down;

[0008] An observation rod is provided on one side of the extrusion disc, and the observation rod passes through the connecting disc, and the stroke of the extrusion disc is judged by the length of the observation rod exposed from the connecting disc;

[0009] The connecting disk is also provided with an air circuit interface, which is connected to one end of an air pipe, the air pipe is wound around the observation rod, and the other end of the air pipe is connected to a nozzle arranged on the top edge of the extrusion disk.

DETAILED DESCRIPTION

[0022] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.

[0023] The utility model provides an ink extrusion device, comprising a vertical pole 1-1, a connecting arm 2-1 sleeved on the vertical pole 1-1, a connecting plate 3-1 connected to the connecting arm 2-1, and an electric hoist 1-2 arranged on the top of the vertical pole 1-1, wherein the electric hoist 1-2 is connected to the connecting plate 3-1 or the connecting arm 2-1 and is used to lift the connecting arm and the connecting plate.

[0024] An extrusion cylinder 4-2 is provided on the top of the connection disk 3-1. The telescopic end of the extrusion cylinder 4-2 passes through the connection disk 3-1 and is connected to the extrusion disk 4-1 located below the connection disk 3-1. The extrusion cylinder 4-2 drives the extrusion disk 4-1 to move up and down.

[0025] An observation rod 3-2 is provided on one side of the extrusion disc 4-1. The observation rod 3-2 passes through the connection disc 3-1. The stroke of the extrusion disc 4-1 can be judged by the length of the observation rod 3-2 exposed from the connection disc 3-1.

[0026] The connecting disk 3-1 is also provided with an air circuit interface 5-1, which is connected to one end of an air pipe 5-2, the air pipe 5-2 is wound around the observation rod 3-2, and the other end of the air pipe 5-2 is connected to a nozzle 5-3 arranged on the top edge of the extrusion disk 4-1.

[0027] A clamp 3-3 is provided on the top edge of the connecting plate 3-1, and the clamp 3-3 is used to clamp the edge of the ink tank 6-1.

[0028] A plastic bag 4-3 is sleeved on the outside of the connecting disk 3-1, and the nozzle 5-3 releases air to expand the plastic bag.

[0029] A plurality of reinforcing ribs are provided on the top of the connecting plate 3-1.

[0030] The specific workflow is as follows:

[0031] S1 puts the ink material into the ink tank 6-1. Operate the extrusion oil cylinder 4-2 to lift the extrusion disc 4-1 back to the initial position, and put a plastic bag 4-3 on the extrusion disc 4-1. Operate the electric hoist 1-2 to drop the connection disc 3-1 connected to one end of the electric hoist 1-2. When the connection disc 3-1 falls to the top of the ink tank 6-1, stop driving the electric hoist 1-2, and operate the clamp 3-3 to clamp the edge of the ink tank 6-1 to lock the ink tank 6-1.

[0032] S2 operates the electric hoist 1-2 to lift the connecting plate 3-1 which is connected with the ink tank, and stops after lifting it to the position where the ink tank can extrude the material.

[0033] S3 operates the gas circuit interface 5-1 to inject high-pressure gas, and the gas enters the nozzle 5-3 along the gas pipe 5-2. The nozzle 5-3 sprays gas to fill the plastic bag 4-3, so that the gap between the extrusion disk 4-1 and the tank wall of the ink tank 6-1 is filled with the plastic bag filled with high-pressure gas, thereby preventing the ink from overflowing from the gap during the extrusion process.

[0034] S4 operates the squeezing oil cylinder 4-2 to drive downward, driving the squeezing plate 4-1 to squeeze out the viscous ink material, and the ink can be discharged from the openable valve at the bottom of the ink tank.

[0035] S5 After all the extrusion work is completed. Operate the electric hoist 1-2 to lower the ink tank and the connecting plate 3-1 to the ground, and release the clamp 3-3 from the ink tank. Operate the extrusion cylinder 4-2 to lift, drive the extrusion plate 4-1 to lift, and operate the electric hoist 1-2 to lift the connecting plate 3-4 to a height that the worker can operate. Remove the plastic bag 4-3 with ink on the extrusion plate 4-1. After removing the plastic bag, the extrusion plate is still clean and uncontaminated.

[0036] S6 When a new round of work is needed, a new ink tank is pushed under the mechanism, and a new plastic bag 4-3 is set on the extrusion disc 4-1 and the above operation is repeated.

[0037] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
