Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of powder material conveying, and in particular relates to a feeding device. Background Art
[0002] Water-based ink is referred to as water-based ink. The raw materials used in its production process include water-based resin, pigment, additive, and solvent. Usually, the pigment is solid powder, and the packaging method is kraft paper bags or lined plastic bags. During its use, it needs to be unpacked and poured. At the same time, because the powder is light, the powder flying during feeding has a greater impact on the environment and workers' health. Today's ink manufacturers will pay attention to such situations during production, but due to the complex structure of large-scale feeding equipment, high land occupation and use costs, some manufacturers do not use mechanical equipment, and directly use manual operation, which is more harmful to personnel. The materials in the feeding bin need to be filtered through the screen before being transported backwards, and the screen is also prone to clogging during filtering, resulting in the inability to smoothly transport the materials. Utility Model Content
[0003] The utility model aims to provide a feeding device which can reduce the dispersion of powder materials when feeding and can smoothly convey materials.
[0004] Based on the above purpose, the utility model adopts the following technical solutions:
[0005] A feeding device comprises a feeding bin, a screen is arranged in the feeding bin, a collecting pipe connected to the feeding bin is arranged below the screen, and the collecting pipe is connected to a negative pressure device; a front feeding port and an upper feeding port are opened on the feeding bin, and a supporting platform is arranged below the front feeding port.
[0006] Furthermore, the negative pressure device includes a gas pipeline connected to the collecting pipeline, and the gas pipeline is connected to the negative pressure equipment.
[0007] Furthermore, a pneumatic percussion hammer is provided on the collecting pipe.
[0008] Furthermore, the collecting pipeline includes a concentrated section connected to the feeding bin, the concentrated section is a trumpet-shaped structure with a larger upper part and a smaller lower part, and a pneumatic percussion hammer is arranged on the concentrated section.
[0009] Furthermore, cover plates are provided at the front feeding port and the upper feeding port, and the cover plates are rotatably connected to the feeding bin; a telescopic support rod is connected between the cover plate at the front feeding port and the feeding bin, and the two ends of the telescopic support rod are respectively rotatably connected to the cover plate at the front feeding port and the feeding bin.
[0010] Furthermore, the feeding bin is fixedly connected with a bracket, the bracket includes at least three supporting legs, and the supporting platform is fixedly connected to the bracket.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. By setting a negative pressure device to form a negative pressure in the collection pipe, the dispersed materials can be gathered to the collection pipe below during feeding, reducing the scattering of powder materials, improving the working environment, and effectively reducing the impact of solid dust on the health of workers. A support platform is set up, and the bagged materials can be placed on the support platform and fed to the feeding port during manual feeding, which is convenient and labor-saving operation.
[0013] 2. Setting the starting hammer can vibrate the screen so that the material can be smoothly transported backwards. The pneumatic hammer and the negative pressure device can speed up the material transportation.
[0014] 3. Set the concentrated section to a structure with a large top and a small bottom to facilitate feeding from the top, increase the filtering area of the upper screen, and quickly filter and convey materials downward. The front and upper covers can be opened and closed after adding part of the powder, or after cutting the powder package and putting it into the feeding bin together with the package, close the cover and seal the feeding bin to reduce the scattering of powder during the feeding process. Setting a bracket can stably support the feeding bin so that the feeding bin can stably convey materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] A feeding device, such as Figure 1-2 As shown, it includes a bracket 1, and the bracket 1 includes four vertical supporting legs; on the bracket 1 is a feeding bin 2 fixedly connected thereto, and the feeding bin 2 is provided with a front feeding port 3 and an upper feeding port 4, the front feeding port 3 is inclined forward from top to bottom, and a supporting platform 5 fixedly connected to the bracket 1 is arranged below the front feeding port 3, the supporting platform 5 is fixedly connected to the top end of the bracket 1, and the supporting platform 5 is horizontally arranged in front of the front feeding port 3; the front and rear length of the supporting platform 5 is 15 cm.
[0019] Both the front feeding port 3 and the upper feeding port 4 are provided with cover plates 6, and the cover plates 6 are rotatably connected to the feeding bin 2; the top end of the cover plate 6 at the front feeding port 3 is rotatably connected to the feeding bin 2, and a pair of telescopic struts 7 are connected between the cover plate 6 at the front feeding port 3 and the feeding bin 2, and the pair of telescopic struts 7 are provided on the left and right sides of the front feeding port 3, and the two ends of the telescopic struts 7 are rotatably connected to the cover plate 6 at the front feeding port 3 and the feeding bin 2 respectively; the telescopic struts 7 are hydraulic struts.
[0020] A screen 8 is fixedly arranged in the feeding bin 2 at a height flush with the top of the bracket 1. The screen 8 is made of metal and has a mesh diameter of 1 cm. A collecting pipe connected to the bottom of the feeding bin 2 is arranged below the screen 8. The upper part of the collecting pipe is a concentrating section 9 connected to the feeding bin 2. The concentrating section 9 is a trumpet structure with a large top and a small bottom. A pneumatic percussion hammer 10 is arranged on the outer side of the concentrating section 9. A cylindrical conveying section is arranged below the concentrating section 9. The collecting pipe is connected to a negative pressure device. The negative pressure device includes a gas pipe 11 connected to the concentrating section 9. The gas pipe 11 is connected to an air pump to make the collecting pipe in a slightly negative pressure state.
[0021] When feeding the powder, keep the air pump turned on, maintain the collection pipe in a slightly negative pressure state, and then choose to open the front or upper movable cover 6 according to the powder packaging method. The front cover 6 can be opened for a 25 kg small package. The operator cuts open the packaging bag and puts it into the feeding bin 2, closes the cover 6, and starts the pneumatic hammer 10 to complete the feeding. When feeding tons of powder, the upper cover 6 can be opened, and the feeding bin 2 can be closed after a certain amount of powder is added, and the pneumatic hammer 10 is started to complete the feeding. The pneumatic hammer 10 drives the feeding bin 2, the metal screen 8, and the powder collection pipe to vibrate at the same time, so that the powder enters the collection pipe below. After the powder in the feeding bin 2 is finished, open the cover 6. Since the bottom is in a slightly negative pressure state, the powder will not fly around when the cover 6 is opened, reducing the environmental and personnel hazards that may be caused by the scattering of solid powder.
