Description

Technical Field

[0001] The utility model belongs to the technical field of weighing and filling materials for powder coating storage tanks, and particularly relates to a weighing and filling material device for a powder coating storage tank. Background Art

[0002] Powder coatings are completely different from general coatings in that they exist in the form of fine powder. Powder coatings are mainly divided into two categories: thermoplastic powder coatings and thermosetting powder coatings. Thermoplastic powder coatings are composed of ingredients such as thermoplastic resins, pigments, fillers, plasticizers, and stabilizers. Thermoplastic powder coatings include polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, and polyester. Thermosetting powder coatings are composed of thermosetting resins, curing agents, pigments, flavorings, and additives. Thermosetting powder coatings include epoxy resins, polyester resins, and acrylic resins.

[0003] For example, a Chinese patent (publication number: CN201920154926.4) discloses a weighing and filling device for a storage tank for powder coatings. Although the weighing and filling device for a storage tank for powder coatings includes an elliptical track, a drive chain is provided on the elliptical track along its inner circle, and a support platform is provided on the upper periphery of the drive chain using its chain links. The bottom surface of the support platform is centrally symmetrically installed with universal casters. The upper surface of the elliptical track is provided with an annular guide groove that matches the motion trajectory of the universal casters to solve the problem in the traditional technology that a large amount of labor is required to remove the storage tank from the conveying platform according to the weighing needs and the high failure rate of the conveying platform. However, the weighing and filling device for a storage tank for powder coatings is not convenient for the user to fill the storage tank in time. In actual production, the phenomenon of insufficient material being taken by the material taking mechanism often occurs due to lack of material in the storage tank. Since the material taking mechanism continues to take the material according to the program, the proportioning accuracy of the powder coating is reduced. Therefore, a weighing and filling device for a storage tank for powder coatings is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a weighing and feeding device for a storage tank of powder coatings, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a material storage tank weighing and feeding device for powder coating, comprising a central processing module and a protective box, the output of the central processing module is connected to the input end of the control module, the output end of the control module is connected to the input end of the discharge module, the output end of the control module is connected to the input end of the feeding module, the input end of the central processing module is connected to the output of the weighing module, the control module comprises a first controller and a second controller, the discharge module comprises a discharge valve, the feeding module comprises a feeding valve, the weighing module comprises a weighing sensor, and a material storage tank is provided inside the protective box.

[0006] As a preferred embodiment, the first controller is connected to the discharge valve, and the second controller is connected to the feed valve.

[0007] As a preferred embodiment, the bottom of the storage tank is connected to the top of the weighing sensor, a signal transmitter, a first controller and a second controller are provided on one side of the weighing sensor, a discharge trough is provided on the other side of the weighing sensor, a discharge box is provided on one side of the bottom of the protective box, the discharge trough is connected to the discharge box, a support block is provided on the other side of the bottom of the protective box, the protective box is connected to the storage tank and the weighing sensor, the interior of the discharge box is inclined, and the inner bottom of the storage tank is inclined.

[0008] As a preferred embodiment, a feeding pipe is provided on one side of the storage tank, a feeding valve is provided at one end of the feeding pipe, and a discharge valve is provided at the bottom of the storage tank through a groove.

[0009] As a preferred embodiment, the control module is used to control the opening and closing of the discharge module and the feeding valve, and the weighing module is used to weigh the powder coating inside the storage tank.

[0010] As a preferred embodiment, the control module is used to control the opening and closing of the discharge module and the feeding valve, and the weighing module is used to weigh the powder coating inside the storage tank.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model can weigh the powder coating raw materials in the storage tank by being provided with a weighing module, and can enable the user to set an upper limit and a lower limit for the weighing module in advance through the control module, thereby controlling the amount of the powder coating raw materials inside the storage tank, preventing the storage tank from lacking material, which would cause the material taking mechanism to take insufficient material and thus affect the ratio of the powder coating; the control module can also control the discharge amount of the storage tank, thereby making the powder coating raw material taking ratio more accurate, thereby improving the quality of the powder coating.

[0013] The utility model sets a discharge amount for the weighing sensor of the weighing module through the control module, and sends a signal to the first controller through the signal transmitter when each discharge reaches the set preset discharge amount, so that the first controller controls the discharge valve of the discharge module to be closed through signal transmission, thereby controlling the discharge of the discharge trough. This process can be controlled automatically, which is extremely convenient for users to use. There is no need to manually proportion the discharged raw materials frequently, which greatly reduces the user's labor. The control module sets an upper limit value and a lower limit value for the weighing weight of the weighing sensor of the weighing module. When the amount of powder coating raw materials inside the storage tank is lower than the lower limit of the weighing weight of the weighing sensor, the signal is transmitted to the second controller through the signal transmitter, so that the second controller controls the feeding valve on the feeding pipe to open and feed the storage tank through signal transmission. When the amount of powder coating raw materials inside the storage tank exceeds the upper limit of the weighing weight of the weighing sensor, the feeding valve is controlled to be closed to prevent the production of powder coating from being affected due to insufficient remaining material in the storage tank when the machine is running automatically.
