Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary production equipment for metal treatment agents, and in particular to a quantitative feeding device for the production of metal surface treatment agents. Background Technology

[0002] Metal surface treatment agents refer to the general term for chemical agents used to treat metal surfaces in various ways. Metal surface treatment includes substrate pretreatment such as degreasing, rust removal, phosphating, and rust prevention.

[0003] During the production of metal surface treatment agents, various powders need to be mixed with solvents in a certain proportion. Currently, the powders are mostly added manually into the reaction equipment, which makes it difficult to strictly control the amount of powders and to automatically feed multiple powders in a quantitative manner. This reduces the feeding speed, easily causes dosage errors, and results in differences in the properties of the metal surface powders, affecting the user's use. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a quantitative feeding device for the production of metal surface treatment agents.

[0005] The technical solution of this utility model is achieved through the following scheme: a quantitative feeding device for the production of metal surface treatment agents, including a mixing tank, a feeding hopper and a feeding box, wherein a plurality of the feeding boxes are supported on the mixing tank by a main support frame, and a feeding hopper is supported above the feeding box by an auxiliary support frame. A quantitative feeding system is provided on the feeding hopper and inside the feeding box. A storage box is rotatably installed inside the feeding box by a storage tilting device. A crushing component and a quantitative feeding device are sequentially installed at the discharge port of the feeding box.

[0006] Through the above technical solutions, the device can automatically and accurately control the amount of powder added by the quantitative feeding system and the quantitative feeding device, which solves the problem that it is difficult to strictly control the powder dosage by traditional manual feeding, reduces human error, and improves the stability of product quality. The crushing component crushes the powder that is clumped or large, while the quantitative feeding device ensures that the powder is added to the mixing tank at a uniform speed and amount, thereby improving the utilization rate of powder and the mixing effect.

[0007] Preferably, the quantitative feeding system includes an electric valve and a pressure sensor, wherein the electric valve is communicatively connected to the pressure sensor, the electric valve is installed on the feeding hopper, and the pressure sensor is embedded in the storage box.

[0008] Through the above technical solution, the pressure sensor monitors the weight change of the powder in the storage box in real time. When the preset weight threshold is reached, the pressure sensor controls the electric valve to close, thereby stopping the powder dispensing and ensuring the accuracy of the powder dispensing amount.

[0009] Preferably, the crushing assembly includes a second motor and crushing rollers, with a plurality of crushing rollers rotatably installed at the discharge port of the feeding box, and the crushing rollers are externally connected to the drive end of the second motor, which is located on the outer side of the feeding box.

[0010] Preferably, the quantitative feeding device includes a third motor and a quantitative feeding tray, with a plurality of the quantitative feeding trays connected to the third motor by rotating shafts, and the quantitative feeding trays being adapted to the discharge port of the feeding box.

[0011] Preferably, the storage box is positioned directly opposite the feeding hopper.

[0012] Preferably, the inner cavity of the feeding box is provided with feeding slopes on both sides.

[0013] The above technical solutions utilize crushing rollers to crush the powder at the discharge port of the feeding box, resulting in more uniform powder particle size, which is beneficial for subsequent mixing and processing, and guides the powder towards the discharge port. By using a quantitative feeding tray that is compatible with the discharge port of the feeding box, the amount of material added each time can be precisely controlled, meeting the precise requirements of different production needs for the amount of material added, thereby improving product quality and production efficiency.

[0014] In summary, this utility model has the following beneficial effects:

[0016] 2. The pressure sensor monitors the weight change of the powder in the storage box in real time. When the preset weight threshold is reached, the pressure sensor controls the electric valve to close, thereby stopping the powder dispensing and ensuring the accuracy of the powder dispensing amount.

[0017] 3. The powder at the discharge port of the feeding box is crushed by crushing rollers to make the powder particles more uniform in size, which is beneficial to subsequent mixing and processing, and guides the powder to move towards the discharge port; the quantitative feeding plate is adapted to the discharge port of the feeding box to precisely control the amount of material added each time, meet the precise requirements of different production needs for the amount of material added, and improve product quality and production efficiency.

[0026] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] A quantitative feeding device for the production of metal surface treatment agents, such as Figures 1-7As shown, the system includes a mixing tank 7, a hopper 1, and a feeding box 3. Several feeding boxes 3 are mounted on the mixing tank 7 via a main support frame. The hopper 1 is mounted above the feeding box via an auxiliary support frame. Both the hopper 1 and the feeding box 3 are equipped with a quantitative feeding system 2. A storage box 6 is rotatably installed inside the feeding box 3 via a storage tilting device 8. A crushing component 4 and a quantitative feeding device 5 are sequentially installed at the discharge port of the feeding box 3. The storage box 6 faces the hopper 1. Feeding slopes are provided on both sides of the inner cavity of the feeding box 3. The feeding box 3 is preferably two in number. Each feeding box 3 is detachably equipped with a feeding hopper 1. The inner walls of the feeding box 3 are provided with inclined slopes on both sides to form an upper funnel-shaped structure, which ensures that the material automatically gathers to the discharge port. The storage box 6 is located at the top and rotates. The storage flipping device 8 includes a fourth motor and a rotating shaft. The rotating shaft passes through the storage box 6. The fourth motor drives the rotating shaft, thereby driving the storage box 6 to achieve periodic flipping and feeding. The electric valve 21 on the feeding hopper 1 is normally open.

[0029] like Figure 1 and Figure 3 As shown, the side of the feeding box 3 has a sliding door, which makes it easy for staff to clean the feeding box 3. The auxiliary support frame is screwed on the top of the feeding box 3. After removing the auxiliary support frame, the sliding door can be opened for cleaning. The side of the feeding box 3 opposite to the sliding door has an observation window, which makes it easy for staff to observe and control the operation of the various devices inside the box.

[0030] like Figure 3 As shown, the quantitative feeding system 2 includes an electric valve 21 and a pressure sensor 22. The electric valve 21 is communicatively connected to the pressure sensor 22. The electric valve 21 is installed on the feeding hopper 1, and the pressure sensor 22 is embedded in the storage box 6. The electric valve 21 controls the opening and closing of the feeding hopper 1 and adjusts the material flow rate. It is directly installed on the feeding hopper 1. The pressure sensor 22 monitors the pressure change of the material in the storage box 6 in real time and reflects the weight of the material. When the set value is reached, it transmits the signal to the electric valve 21 to close, thus completing one quantitative feeding cycle.

[0031] The crushing assembly 4 includes a second motor 41 and crushing rollers 42. Several crushing rollers 42 are rotatably installed at the discharge port of the feeding box 3. The crushing rollers 42 are externally connected to the drive end of the second motor 41. The second motor 41 is located on the outer side of the feeding box 3. Preferably, there are two crushing rollers 42 to form a roller-pair structure. Material crushing is achieved through relative rotation. The number of second motors 41 and crushing rollers 42 is the same. The crushing rollers 42 are bidirectional screw rollers, which guide the powder to the discharge port while crushing the powder, effectively avoiding blockage.

[0032] The quantitative feeding device 5 includes a third motor 51 and a quantitative feeding tray 52. ​​Several quantitative feeding trays 52 are connected to the third motor 51 by rotating shafts. The quantitative feeding trays 52 are adapted to the discharge port of the feeding box 3. The number of quantitative feeding trays 52 is preferably two, which is the same as the number of feeding boxes 3. The third motor 51 is mounted on the main support frame. The two quantitative feeding trays 52 are coaxially designed. The quantitative feeding tray 52 consists of a turntable and a quantitative feeding trough. Four quantitative feeding troughs are opened on the turntable and are arranged in a 90° array along the circumference of the turntable. When the trough rotates to the bottom, the material is automatically discharged into the mixing tank 7 due to gravity, completing one quantitative feeding. The material enters the mixing tank 7 for mixing. Quantitative feeding is added to the mixing tank 7 each time, which facilitates the mixing and stirring of powder and solvent in production.

[0033] The mixing shafts inside the mixing tank 7 have a staggered array of mixing fans. The mixing fans near the bottom of the inner cavity of the mixing tank 7 not only play a role in mixing but also in pushing the treatment agent. The air blower is turned on to discharge the metal treatment agent from the discharge port. The mixing tank 7 is also equipped with a solvent inlet. The operator introduces the solvent according to the material list and mixes it with the powder.

[0034] Working principle: The staff introduces different powders into different feeding hoppers 1. At this time, the powder flows into the storage box 6 through the discharge port of the feeding hopper 1. When the weight of the powder in the storage box 6 reaches the set value of the pressure sensor 22 in the box, the pressure sensor 22 senses and controls the electric valve 21 to close, stopping the feeding. At this time, the staff starts the storage tilting device 8 to tilt the storage box 6, pouring out the powder in the storage box 6. Further powder is guided into the gap between the rollers by the feeding slope, and is crushed by the squeezing and shearing action of the bidirectional screw rollers. The crushed powder after solidification is conveyed axially to the discharge port.

[0035] At this time, the powder accumulates at the discharge port and flows to the metering feed tray 52 that is blocked at the discharge port. Observe through the observation window, start the third motor 51 to drive the metering feed tray 52 to feed the powder in a metered manner, and at the same time start the mixing tank 7 to stir and mix the solvent and the powder put in the mixing tank 7.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
