Description

Technical Field

[0001] The utility model relates to the technical field of ink production, in particular to an automatic powder feeding structure for ink production. Background Art

[0002] Ink is a liquid containing pigments or dyes. Ink is used for digital printing. Ink is generally made of soluble colored pigments, mixed solvents, additives and other materials. The dyes used in ink production are generally powdered and need to be sealed and stored.

[0003] In order to load solid materials into a closed container, a common method is to use a vacuum generator to extract the air in the container to form a pressure difference. To maintain pressure balance, the air will flow into the closed cavity through the raw material inlet. During the high-speed flow of air, the raw materials will be driven into the cavity together.

[0004] Since the density of raw materials is greater than that of air, they will sink to the bottom after entering the cavity and will not be discharged from the container along with the vacuum generator. As long as the vacuum generator keeps working and the cavity is not completely filled with raw materials, the raw materials need to be transported continuously.

[0005] The above is the working principle of the common storage structure, but this structure cannot be used for the powder casting structure in the ink industry, and has the following disadvantages;

[0006] The raw material must be heavier than air and cannot float in the air, otherwise it will not sink to the bottom of the cavity;

[0007] The raw materials must be larger particles, otherwise they will be discharged along with the vacuum generator;

[0008] For containers with particularly large cavities, the effect drops sharply.

[0009] In view of the above problems, it is urgent to carry out innovative design based on the original powder casting structure. Utility Model Content

[0010] The purpose of the utility model is to provide an automatic powder feeding structure for ink production to solve the problem proposed in the above background technology that the raw materials must be heavier than air and cannot float in the air, otherwise they cannot sink to the bottom of the cavity, and the raw materials must be larger particles, otherwise they will be discharged together with the vacuum generator. For containers with particularly large cavities, the effect drops sharply.

[0011] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic powder feeding structure for ink production, comprising a storage tank body and a feed pipe fixedly installed at the upper end of the storage tank body;

[0012] A vacuum generator is fixedly installed on the upper end of the feed pipe, and an air outlet pipe is fixedly installed inside the vacuum generator. The vacuum generator is located just above the feed pipe, and a filter is fixedly installed inside the upper end of the feed pipe.

[0013] Preferably, a positive pressure air pipe assembly and a pressure sensor are fixedly installed on the outside of the feed pipe, and a vibration generator is fixedly installed inside the feed pipe, and the positive pressure air pipe assembly and the pressure sensor are located at the upper end of the vibration generator.

[0014] Preferably, a butt-joint pipe and a butterfly valve pipe are fixedly installed on the outer side of the feed pipe, and the butt-joint pipe and the butterfly valve pipe are respectively located at the upper and lower ends of the vibration generator.

[0015] Preferably, a fixed base is fixedly installed at the lower end of the storage tank body, and two groups of support plates are fixedly installed at the lower end of the fixed base, and a discharge pipe is fixedly installed at the lower end of the storage tank body.

[0016] Preferably, two groups of movement grooves are opened inside the support plate, and movement blocks are slidably installed inside the movement grooves, and a movement plate is fixedly installed on one side of the movement block close to the middle position of the fixed base.

[0017] Preferably, a driving motor is fixedly mounted on the lower end of the fixed base, an output shaft is fixedly mounted on the output end of the driving motor, and a rotating shaft is rotatably mounted on the lower end of the fixed base, and a pulley structure is provided on the outer side of the rotating shaft and the output shaft.

[0018] Preferably, two sets of fixed cylinders are fixedly installed on the upper end of the moving plate, and the fixed cylinders are respectively sleeved on the outside of the output shaft and the rotating shaft, and the fixed cylinders are respectively threadedly connected to the output shaft and the rotating shaft, and a movable roller is rotatably installed on the lower end of the moving plate.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. This structure adopts intermittent feeding, and each section of feeding is precisely controlled to improve the accuracy of feeding;

[0021] 2. A butterfly valve is provided under the feed chamber. When the negative pressure is pumped out, the butterfly valve is closed, which reduces the time and energy consumption of pumping out the negative pressure;

[0022] 3. A pressure sensor is installed in the feed chamber to sense the toner adsorption on the filter. When the negative pressure does not reach the set value, the internal valve of the positive pressure air pipe assembly is activated to blow out the raw materials adsorbed on the filter to reduce weight error.

[0023] 4. After the toner fills the feeding chamber, turn off the vacuum generator and open the butterfly valve. Some toner gathered at the bottom falls into the closed chamber under the action of the vibration generator.

[0024] 5. Because the toner particles are small, they are adsorbed on the filter and cannot fall naturally. The filter is equipped with a positive pressure back-blowing air pipe, which performs a blowing action to blow the tiny toner into the closed cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In a specific embodiment, Figure 1 , Figure 3 and Figure 5 As shown, including:

[0033] A storage tank body 1 and a feed pipe 2 fixedly installed on the upper end of the storage tank body 1;

[0034] A vacuum generator 3 is fixedly installed at the upper end of the feed pipe 2, and an air outlet pipe 4 is fixedly installed inside the vacuum generator 3. The vacuum generator 3 is located just above the feed pipe 2, and a filter screen 5 is fixedly installed inside the upper end of the feed pipe 2.

[0035] A positive pressure air pipe assembly 6 and a pressure sensor 7 are fixedly installed on the outside of the feed pipe 2, and a vibration generator 9 is fixedly installed inside the feed pipe 2, and the positive pressure air pipe assembly 6 and the pressure sensor 7 are located at the upper end of the vibration generator 9;

[0036] A butt joint pipe 8 and a butterfly valve pipe 10 are fixedly installed on the outer side of the feed pipe 2 , and the butt joint pipe 8 and the butterfly valve pipe 10 are respectively located at the upper and lower ends of the vibration generator 9 .

[0037] During the use of the powder feeding structure, it is necessary to connect the docking tube 8 with the feeding equipment so that the ink powder can enter the feed pipe 2 through the docking tube 8, and then the vacuum generator 3 and the vibration generator 9 can be operated. The operation of the vibration generator 9 will cause the powder inside the feed pipe 2 to enter the storage tank body 1, and the vacuum generator 3 will cause the air inside the storage tank body 1 and the feed pipe 2 to be discharged through the air outlet pipe 4. The ink powder will float during the injection process, and the filter 5 will reduce the powder from being discharged along the air outlet pipe 4, thereby ensuring the convenience of using the powder feeding structure.

[0038] In one embodiment, if Figure 1-Figure 5 As shown;

[0039] A fixed base 12 is fixedly installed at the lower end of the storage tank body 1, and two sets of support plates 13 are fixedly installed at the lower end of the fixed base 12, and a discharge pipe 11 is fixedly installed at the lower end of the storage tank body 1;

[0040] Two sets of movement grooves 14 are provided inside the support plate 13, and movement blocks 15 are slidably installed inside the movement grooves 14, and a movement plate 16 is fixedly installed on one side of the movement block 15 close to the middle position of the fixed base 12;

[0041] A driving motor 17 is fixedly mounted on the lower end of the fixed base 12, and an output shaft 18 is fixedly mounted on the output end of the driving motor 17, and a rotating shaft 19 is rotatably mounted on the lower end of the fixed base 12, and a pulley structure 20 is sleeved on the outer sides of the rotating shaft 19 and the output shaft 18;

[0042] Two sets of fixed cylinders 21 are fixedly installed on the upper end of the moving plate 16, and the fixed cylinders 21 are respectively sleeved on the outside of the output shaft 18 and the rotating shaft 19, and the fixed cylinders 21 are respectively threadedly connected to the output shaft 18 and the rotating shaft 19. At the same time, a moving roller 22 is rotatably installed on the lower end of the moving plate 16.

[0043] Before using the automatic powder feeding structure for ink production, the powder feeding structure needs to be moved to the position where it needs to work. Before moving the powder feeding structure, the drive motor 17 needs to be powered and made to work. The drive motor 17 will drive the output shaft 18 to rotate when it works. During the rotation of the output shaft 18, the rotating shaft 19 will be driven to rotate through the pulley structure 20. At this time, the rotating shaft 19 and the output shaft 18 will rotate synchronously in the same direction, so that the fixed cylinder 21 can move vertically downward. During the downward movement of the fixed cylinder 21, the moving block 15 will be driven to move downward inside the moving groove 14 through the moving plate 16. During the downward movement of the moving plate 16, the moving roller 22 will be driven to contact the ground and separate the support plate 13 from the ground. At this time, the powder feeding structure can be moved by the moving roller 22, so that the powder feeding structure can be moved to the required position, which effectively improves the convenience of the movement of the powder feeding structure.

[0044] It is worth mentioning that according to Figure 1-Figure 5 , the specific contents are as follows;

[0045] After the powder throwing structure moves to the required position, the driving motor 17 drives the output shaft 18 to rotate in the opposite direction, so that the fixed cylinder 21 can drive the moving plate 16 to move upward, so that the moving roller 22 can be separated from the ground and the two groups of support plates 13 can contact the ground again, thereby ensuring the stability of the powder throwing structure support and increasing the overall practicality.

[0046] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
