Description

Technical Field

[0001] This utility model relates to the technical field of epoxy topcoat processing equipment, and in particular to a quantitative feeding device for epoxy topcoat processing. Background Technology

[0002] As a high-performance industrial coating, the final properties of epoxy topcoat, such as hardness, adhesion, and chemical resistance, are highly dependent on the precise proportions of its components, including epoxy resin, curing agent, pigments, and fillers. In the production and processing of epoxy topcoats, the raw material feeding stage is a crucial step in ensuring consistent product quality.

[0003] In current production practices, the addition of liquid and solid raw materials is often carried out separately or semi-manually. For example, liquid materials may be added to a mixing container by pumping or manual pouring, while solid powders are usually added manually after weighing. This operation method is not only inefficient, but also prone to introducing human error, resulting in fluctuations in color, gloss, or performance between different batches of products due to slight differences in the raw material ratio.

[0004] With the improvement of industrial automation, although some automated feeding devices have emerged, most of these devices can only achieve quantitative feeding of liquid materials or only handle solid materials. There is a lack of compact equipment that can integrate precise, stable, and quantitative feeding functions for both liquids and solids. This lack of functionality makes it difficult to achieve a high degree of automation and precise control in the epoxy topcoat production process, thus limiting further improvements in product quality stability.

[0005] Therefore, this utility model proposes a quantitative feeding device for epoxy topcoat processing to overcome the shortcomings of the prior art. Utility Model Content

The hydraulic cylinder is installed on the inner wall of the housing and connected to the cover plate, and is used to drive the cover plate to seal the top opening of the processing barrel.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example: Please refer to Figures 1 to 5 This utility model provides a quantitative feeding device for epoxy topcoat processing, which aims to solve the problem that it is difficult to achieve accurate and stable quantitative feeding of liquid and solid raw materials in the feeding process of existing epoxy topcoat processing equipment.

[0025] like Figure 1 and Figure 2 As shown, the quantitative feeding device for epoxy topcoat processing includes a housing 1 and a processing tank 4 disposed inside the housing 1. The housing 1 provides an installation and support platform for the entire device. The processing tank 4 is used to contain and process epoxy topcoat raw materials. The device also includes a motor 5 and a stirring component 6. The motor 5 is fixedly connected to the upper part of the housing 1. One end of the stirring component 6 is drivenly connected to the output shaft of the motor 5, and the other end extends into the interior of the processing tank 4 for mixing and stirring the materials in the processing tank 4. The device further includes a cover plate 3 and at least one hydraulic cylinder 2. The hydraulic cylinder 2 is installed on the inner wall of the housing 1. The drive end of the hydraulic cylinder 2 is connected to the cover plate 3 for driving the cover plate 3 to move to open and close the top opening of the processing tank 4.

[0026] Please refer to the following carefully. Figure 1 , Figure 4 and Figure 5The core liquid feeding mechanism 7 is described in detail below: The liquid feeding mechanism 7 includes a storage tank 71, a cylinder 72, a pusher plate 73, a connecting pipe 74, a delivery pipe 77, and an inlet pipe 9; the cylinder 72 is vertically installed inside the storage tank 71, and the pusher plate 73 is fixedly connected to the end of the piston rod of the cylinder 72, and the outer periphery of the pusher plate 73 forms a sliding fit with the inner wall of the storage tank 71; the bottom of the storage tank 71 is connected to the connecting pipe 74, one end of the connecting pipe 74 is connected to the delivery pipe 77, and the other end of the delivery pipe 77... One end is connected to a liquid outlet pipe 79, the end of which extends into the processing barrel 4, forming a channel for conveying liquid to the processing barrel 4; at the same time, a liquid inlet pipe 9 is connected to a liquid storage tank 71 for replenishing liquid raw materials into the liquid storage tank 71; when the cylinder 72 drives the pusher plate 73 to move, it can change the volume and pressure inside the liquid storage tank 71, thereby drawing in liquid through the liquid inlet pipe 9 or discharging liquid through the liquid outlet pipe 79. This pneumatic piston-type volume control structure ensures a high-precision quantitative supply of liquid raw materials.

[0027] As a preferred embodiment, in order to achieve unidirectional flow of liquid within the pipe, please refer to... Figure 4 and Figure 5 A sealing tube 75 is installed inside the connecting tube 74, and sealing plates 76 are movably installed at both ends of the sealing tube 75. Furthermore, in order to improve the stability of the movement of the sealing plate 76, the liquid feeding mechanism 7 also includes a support assembly 78. The support assembly 78 is composed of connecting columns 781 and support plates 782 arranged in parallel with each other. The two ends of the support plate 782 are respectively fixedly connected between the two connecting columns 781, while the sealing plate 76 is slidably sleeved on the connecting columns 781. The two ends of the connecting columns 781 of the entire support assembly 78 are respectively fixedly connected to the inner wall of the connecting tube 74. More preferably, the sealing plate 76 has a conical structure with its cone tip facing in opposite directions. This structure can be pushed open to form a passage when the liquid flows in the forward direction, and can tightly seal the channel of the sealing tube 75 when reverse pressure is generated.

[0028] In another preferred embodiment, the device also includes a solid feeding assembly 8 for quantitative dispensing of solid raw materials; please refer to... Figure 1 and Figure 3The solid feeding assembly 8 includes a storage tank 81 with an open top. The bottom outlet of the storage tank 81 is directly opposite the processing barrel 4. The outer wall of the storage tank 81 is provided with a scale line 86 for measuring the volume of solid raw materials. A baffle 82 for opening and closing the bottom outlet is provided at the bottom of the storage tank 81. In order to control the movement of the baffle 82, the solid feeding assembly 8 is also provided with a rotating plate 84, a stud 83 and a support block 85. The support block 85 is fixed to the outer wall of the storage tank 81. The rotating plate 84 is fixedly connected to one end of the stud 83. The stud 83 is threaded into the support block 85, and the other end of the stud 83 is connected to the baffle 82. By rotating the rotating plate 84, the stud 83 can be driven to make a spiral movement in the support block 85, thereby driving the baffle 82 to achieve linear displacement, so as to accurately control the opening and closing of the outlet of the storage tank 81.

[0029] The working principle is as follows: When processing epoxy topcoat, first start hydraulic cylinder 2, whose driving force pushes cover plate 3 to move until the top opening of processing bucket 4 is sealed, creating a closed environment for subsequent mixing and stirring.

[0030] Then, liquid is fed in. The cylinder 72 is activated, causing its piston rod to retract and move the pusher plate 73 toward the cylinder 72. This creates a negative pressure inside the storage tank 71. Under atmospheric pressure, the external liquid raw material enters through the inlet pipe 9, flows through the delivery pipe 77 and the connecting pipe 74, and pushes open the sealing plate 76 on one side to enter the storage tank 71 for storage. When it is necessary to inject liquid into the processing barrel 4, the cylinder 72 is driven in reverse, causing its piston rod to extend and push the pusher plate 73 away from the cylinder 72, squeezing the liquid in the storage tank 71. The liquid pressure pushes open the sealing plate 76 on the other side, and finally, through the connecting pipe 74, the delivery pipe 77 and the outlet pipe 79, it is accurately injected into the processing barrel 4.

[0031] Next, solid material is fed into the storage tank 81, and the amount is confirmed by observing the scale line 86. Then, the operator rotates the rotating plate 84, which drives the stud 83 to rotate in the threaded hole of the support block 85. Due to the action of the threaded pair, the stud 83 will produce axial linear displacement, thereby driving the baffle 82 connected to it to move, opening the bottom outlet of the storage tank 81, so that a certain amount of solid material falls stably into the processing barrel 4 under the action of gravity.

[0032] Finally, after all the raw materials have been added, start motor 5. The output shaft of motor 5 drives the stirring component 6 to rotate at high speed inside the processing tank 4, so as to fully and evenly mix the liquid and solid raw materials until the epoxy topcoat is processed.

[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
