Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, specifically to a material feeding device for ink production. Background Technology

[0002] In the ink production process, materials need to be fed into large reaction vessels or dispersion tanks and stirred for a long time. The installation of reaction vessels and dispersion tanks has certain standards. They are usually installed vertically and suspended, with the feeding port located above the reaction vessel or dispersion tank. A platform is set on the upper part of the reaction vessel or dispersion tank to facilitate manual feeding and observation. However, for safety reasons, the feeding port is usually set about 1 meter above the platform. When feeding, the manual laborer needs to lift the whole bag of raw material and pour it into the feeding port, which is not only laborious, but also results in uneven feeding speed and splashing of raw material.

[0003] To address the aforementioned technical problems, the utility model "A Feeding Device for Ink Production" (publication number CN219334131U) discloses a device comprising a cart, a rotating rod, and a feeding channel. The cart has a support plate fixedly mounted on its upper end. A rotating rod is placed on the upper end of the support plate, with screws threaded through both sides of the rotating rod. Nuts are fitted onto the heads of the screws. A motor drives a transmission shaft to rapidly extend and retract the telescopic rod longitudinally, allowing it to lower to its lowest point when material needs to be fed. This allows workers to smoothly and quickly guide the material into the feeding trough. The motor then raises the rod above the feeding channel, where a sliding plate is opened to deliver the material into the channel, which is then poured into the reaction vessel. This method uses the up-and-down movement of the telescopic rod to replace manual lifting, reducing worker fatigue and effectively improving the efficiency of the feeding process.

[0004] However, the above-mentioned patents also have the following problems. Usually, the material of the feeding tank and feeding channel is made of metal such as aluminum alloy or stainless steel. When the ink slides down from the feeding tank and feeding channel, it will rub against the feeding tank and feeding channel, which can easily generate static electricity and create safety hazards.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] A feeding device for ink production includes: a substrate 1, a feeding hopper 3, a rotating plate 17, a grounding strip 6, and a power module.

[0024] The lower end of the substrate 1 is provided with four omnidirectional wheels 2 arranged in a rectangular array; the omnidirectional wheels 2 facilitate the movement of the feeding device of this utility model.

[0025] The feeding hopper 3 is installed above the base plate 1 via a lifting mechanism. The opening of the feeding hopper 3 faces upward, and the bottom of the feeding hopper 3 is inclined downward from one end to the other. A downwardly inclined feeding channel 4 is connected to the lowest position of the bottom of the feeding hopper 3.

[0026] The rotating plate 17 is matched with the feeding channel 4. The rotating plate 17 is set on its side and is driven to rotate by a driving mechanism.

[0027] The grounding strip 6 is connected to the unloading channel 4, and the length of the grounding strip 6 is greater than the height of the unloading channel 4. The length of the grounding strip 6 needs to be long enough so that it can be dragged on the platform. Since the platform is usually a scaffold built with steel pipes, the grounding strip 6 can be grounded.

[0028] A power supply module is disposed on the substrate 1 for supplying power.

[0029] The feeding device of this invention can be moved on the platform by the universal travel wheels 2. The height of the feeding hopper 3 is lowered by the lifting mechanism, so that the powder can be poured into the feeding hopper 3. Then the height of the feeding hopper 3 is raised and the feeding device is moved so that the end of the feeding channel 4 corresponds to the feed port at the top of the reactor or dispersion tank. Then the rotating plate 17 is rotated under the drive mechanism to open the feeding channel 4. The powder in the feeding hopper 3 slides down from the feeding hopper 3 and enters the reactor or dispersion tank along the feeding channel 4. During this process, since the grounding strip 6 is grounded, the static electricity generated on the feeding hopper 3 and the feeding channel 4 can be guided to the ground, avoiding the accumulation of static electricity on the feeding hopper 3 and the feeding channel 4, and reducing the danger factors caused by static electricity.

[0030] In a preferred embodiment, the lifting mechanism includes a rotating tube 8 rotatably mounted on a base plate 1. The rotating tube 8 is vertically arranged and extends vertically through the base plate 1. A through hole 14 is vertically arranged on the base plate 1, communicating with the rotating tube 8. A vertically arranged threaded rod 9 is fixedly mounted at the lower end of the feeding hopper 3. The threaded rod 9 is inserted into the rotating tube 8. An internal thread matching the threaded rod 9 is provided on the inner wall of the rotating tube 8. A worm gear is fixedly mounted on the outer wall of the rotating tube 8. A first motor 12 is mounted on the base plate 1. The output end of the first motor 12 is provided with a worm 11 that meshes with the worm gear. The feeding hopper 3 is connected to a vertical guide mechanism mounted on the base plate 1.

[0031] The lower end of the rotating tube 8 is rotatably mounted on the base plate 1 via a bearing 13. The bearing 13 is located on the outer wall of the rotating tube 8. A mounting groove matching the bearing 13 is provided at the upper end of the base plate 1. The bearing 13 is located in the mounting groove, and its outer ring is fixedly installed in the mounting groove. The lower end of the rotating tube 8 is inserted into the inner ring of the bearing 13 and fixedly installed therein. The feeding hopper 3 can only move vertically due to the restriction of the vertical guide mechanism. The first motor 12 drives the worm gear 11 to rotate, thereby driving the rotating tube 8 to rotate through the cooperation of the worm gear 11 and the worm wheel. Since the threaded rod 9 is threadedly connected to the inner wall of the rotating tube 8, the rotating tube 8 can drive the threaded rod 9 to move vertically when it rotates, thus adjusting the height of the feeding hopper 3 in the vertical direction. The first motor 12 is electrically connected to the power module for power supply.

[0032] In a preferred embodiment, the vertical guiding mechanism includes at least three guide sleeves 15, which are vertically mounted and fixed on the base plate 1. The at least three guide sleeves 15 are distributed around the rotating tube 8, and the lower end of the feeding hopper is fixedly provided with guide rods 19 that slide inside the three guide sleeves 15.

[0033] At least three guide sleeves 15 are distributed at equal angles around the rotating tube 8, and the feeding hopper 3 is guided vertically by the cooperation of the guide rod 19 and the guide sleeve 15.

[0034] In a preferred embodiment, the driving mechanism includes a second motor 18 disposed on the outer wall of the feeding channel 4. The upper end of the rotating plate 17 is rotatably connected to the upper wall of the feeding channel 4 via a rotating shaft 16. The rotating shaft 16 is fixed to the rotating plate 17 and rotatably connected to the feeding channel 4. One end of the rotating shaft 16 extends out of the feeding channel 4 and is connected to the output end of the second motor 18 for transmission.

[0035] The rotating plate 17 is installed in the feeding channel and rotates vertically. It is driven to rotate by the second motor 18. In its natural state, the rotating plate 17 is set perpendicular to the length of the feeding channel, thereby closing the feeding channel and preventing the powder poured into the feeding hopper 3 from slipping. When it is necessary to feed the material into the reactor or dispersion cylinder, the second motor 18 drives the rotating plate 17 to rotate upward, and the direction of rotation of the rotating plate 17 is opposite to the direction of the feeding hopper 3, so as to avoid the powder causing resistance to the opening of the rotating plate 17.

[0036] In a preferred embodiment, the end of the feeding channel 4 is bent downwards and extended to provide a feeding port 5.

[0037] When the feeding channel 4 is tilted, the powder will be thrown out due to inertia. If the stopping position of the feeding device is deviated, the powder will easily spill. By setting the vertically downward feeding port 5, it is easier to align the feeding port 5 with the feed port of the reactor or dispersion tank, so as not to cause the powder to spill.

[0038] In a preferred embodiment, a vibrator 7 is installed at the lower end of the feeding hopper.

[0039] Vibration is generated by vibrator 7, which makes it easier for the powder to slide smoothly from the feeding hopper 3.
