Description

Technical Field

[0001] The utility model relates to the technical field of powder weighing equipment, in particular to an automatic powder weighing, mixing and conveying integrated device. Background Art

[0002] Most of the powder weighing systems currently used in the market rely on manual weighing. After the technician issues a prescription on the production order, it is issued to the weigher for weighing. The worker weighs the materials one by one according to the prescription and process requirements, and the weigher then delivers them to various production locations.

[0003] At present, some enterprises only have a single weighing function, that is, computer program control and reminder are installed, and computers and sound and light alarm devices are added to the weighing room. After the technicians have prepared the process prescription, they directly download it to the computer in the weighing room through the network or print it out as a production order to be scanned by the weighing computer. After that, the computer program will light up the lights in sequence according to the process prescription to remind the weighing workers of the location of the materials. The workers will take the materials to the weighing table to weigh them. The computer program will control the weighing accuracy according to the process prescription requirements. When the weight of the material on the material table exceeds or is less than the gram weight required by the process prescription by ±0.5g, the computer program will not allow the weighing to be completed and the next material cannot be weighed.

[0004] Another way of weighing materials is to use a three-dimensional warehouse to replace the manual material picking process. The weighing process is: on a three-dimensional shelf, dozens or hundreds of material positions are designed, each material position can hold a certain amount of material, and the material box is placed in the designated position for standby through the mechanical device at the bottom. After the technician writes the prescription, the equipment computer is placed through the network or the worker scans the production order after it is opened. After the system receives the instruction, the mechanical device will take the weighed materials in turn and place them on the weighing port. The materials are manually picked up and weighed on the electronic scale. The background system will remind the weighing weight. If the weight does not meet the process requirements, the next weighing will not be allowed.

[0005] The latest weighing method in the industry is: each material is sucked into its own independent storage bin through a vacuum powder suction device for standby use. After the technician prepares the process prescription, the equipment computer is placed under the network. After the system receives the instruction, the screw at the bottom of the storage bin is driven to rotate through the device at the back end of the equipment, and the powder is squeezed out of the storage bin and falls into the barrel in the horizontally moving weighing cart. The weighing cart device has an electronic scale connected to the computer, and the system records and controls the weighing accuracy in real time. However, this method is only suitable for weighing a small amount of dye chemicals. For a large amount of dye chemicals, the weighing efficiency is too low.

[0006] In summary, the defects of the material weighing and reclaiming device in the prior art are as follows: 1. low efficiency; 2. low precision; 3. low degree of automation and high labor intensity for workers; 4. poor stability. Utility Model Content

[0007] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an automatic powder weighing, compounding and conveying integrated device to solve the problem that the prior art has low powder weighing efficiency and is difficult to apply to large amounts of dye chemicals.

[0008] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides an automatic powder weighing, compounding and conveying integrated device, which is characterized in that it includes a compounding cylinder, a plurality of silos arranged next to the compounding cylinder for placing powder, a feeding and conveying mechanism arranged at the bottom of each silo for conveying the powder in the silo to the compounding cylinder, and a weighing device arranged at the bottom of the compounding cylinder for weighing the compounding cylinder, and also includes a control terminal connected to the weighing device and capable of controlling the operation of each feeding and conveying mechanism.

[0009] By adopting the above technical solution, after the formula is determined, the powder can be transported from the corresponding hopper to the dissolving tank through the unloading and conveying mechanism, and the powder is measured by the weighing device at the bottom of the dissolving tank. After reaching the required weight, another hopper is opened for unloading until the complete formula is matched. Then, the dissolving tank automatically completes the actions of adding water, stirring, conveying, cleaning, etc. to dissolve the dye and transmit it to the dyeing equipment. The device of the utility model makes the weighing, dissolving and feeding of the powder truly seamless, achieves true automated control, and greatly improves production efficiency; and only one person is needed to operate the entire system, and is only responsible for the simplest loading work, which greatly reduces the factory's labor and human factors.

[0010] In one embodiment of the present invention, the discharge conveying mechanism includes a discharge pipe connected to the bottom of the silo, a discharge screw connected to the discharge pipe and rotating along the axis of the discharge pipe, and a drive motor driving the discharge screw to rotate. It also includes a discharge buckle cover arranged at the outlet end of the discharge pipe and an opening cylinder arranged outside the discharge pipe to control the opening and closing of the discharge buckle cover.

In addition, in combination with the discharge cover, the opening and closing of the discharge pipe powder conveying can be controlled in the first time, and the control of the powder conveying amount can be more accurate.

[0012] In one embodiment of the present invention, the silo is located above the material-forming cylinder, and a plurality of the silos are arranged in parallel on both sides of the material-forming cylinder, and the discharge pipe under each silo extends to the top of the material-forming cylinder.

[0015] By adopting the above technical solution, the discharge pipe can discharge materials corresponding to the discharge port, and the dust-proof powder cover can be used to solve the dust problem during discharge and avoid pollution.

[0016] In one embodiment of the present invention, each of the silos is also provided with a feeding mechanism for powder to enter the silo, and the feeding mechanism includes a feeding pipe connected to the silo, a negative pressure fan arranged on the feeding pipe to drive the powder to move, and a fan filter arranged on the output end of the negative pressure fan.

[0017] By adopting the above technical solution, the powder can be input into the corresponding silo by using the feeding fan as a power source.

[0018] In one embodiment of the present invention, a dust suction filter assembly is also provided on the top of the silo, and the dust suction filter assembly includes a filter element installed on the top of the silo, a filter screen provided on the lower side of the filter element, and an air intake pipe provided on the filter element, and a nozzle is installed at one end of the air intake pipe.

[0019] By adopting the above technical solution, the dust on the filter element can be cleaned to prevent the filter from being blocked.

[0020] In one embodiment of the present invention, a separating plate is further provided at the outlet end of the discharge pipe to enable the powder to be discharged evenly. The separating plate is semicircular and has a plurality of through holes evenly distributed on the separating plate for the powder to pass through.

[0021] By adopting the above technical solution, the powder can be made more uniform when the discharge pipe discharges the powder, and the discharge control of the powder is more convenient.

[0022] In one embodiment of the present invention, a side wall of the material-forming tank has a water inlet pipe for liquid to enter the interior of the tank, and an agitator is provided in the material-forming tank.
