Description

Technical Field

[0001] This utility model belongs to the field of vertical coating machine manufacturing technology, specifically relating to a reciprocating automatic mixing and circulating equipment. Background Technology

[0002] CN 207308221 U, entitled "A Double-Sided Vertical Coating Mechanism," includes an adhesive trough for receiving adhesive, a guide roller disposed within the adhesive trough, a traction roller disposed above the guide roller, and a scraper assembly disposed between the guide roller and the traction roller. The guide roller and the traction roller are arranged parallel to each other, and the vertical tangent of the guide roller is collinear with the vertical tangent of the traction roller. The traction roller pulls the film sequentially through the guide roller and the scraper assembly to the traction roller. The scraper assembly includes two scrapers symmetrically disposed on both sides of the film, and the adhesive liquid level in the adhesive trough is located between the lowest point of the scraper assembly and the scrapers. The scraper assembly also includes two comma-shaped scraper rollers symmetrically disposed on both sides of the film, with the two scrapers respectively disposed on the side of the two comma-shaped scraper rollers closest to the film. The adhesive liquid level in the adhesive trough is located between the lowest points of the scrapers and the comma-shaped scraper rollers. The central axes of the scrapers and the comma-shaped scraper rollers are on the same horizontal plane. At least two-fifths of the comma-shaped scraper roller is located below the surface of the adhesive liquid in the coating tank. The surface of the adhesive liquid in the coating tank is flush with the scraper blade. The distance between the two scraper blades is between 0.2 mm and 1.0 mm. The double-sided vertical coating mechanism also includes a feed box, a pipe connecting the feed box and the coating tank, and a one-way valve installed on the pipe. A liquid level sensor is installed on the inner wall of the coating tank. The one-way valve is a solenoid valve, and the solenoid valve is signal-connected to the liquid level sensor. The double-sided vertical coating mechanism also includes an oven located between the scraper assembly and the traction roller. Its drawback is that the uniformity of the material in the coating tank of this double-sided vertical coating mechanism is relatively poor, which to some extent affects the coating effect on the fabric. Utility Model Content

[0003] Design objective: To overcome the shortcomings of the prior art, this design aims to create a reciprocating automatic mixing and circulating equipment that not only improves the uniformity of the material slurry and the uniformity of the coating, but also ensures the dynamic balance of the material in the coating tank and achieves good performance.

[0004] Design scheme: To achieve the above design objectives.

[0005] 1. The lower part of the paint roller is located inside the paint tank, and a guide roller is provided directly above the paint roller. The lower part of the paint tank has an outlet, and the upper part of the paint tank has an inlet. The upper part of the storage tank has an inlet, and the lower part of the storage tank has an outlet. The outlet of the paint tank is connected to the inlet of a first pneumatic diaphragm pump via a connecting pipe, and the outlet of the first pneumatic diaphragm pump is connected to the inlet of the storage tank via a connecting pipe. The inlet of the paint tank is connected to the outlet of a second pneumatic diaphragm pump via a connecting pipe, and the second pneumatic diaphragm pump... The design of connecting the pump's inlet to the storage tank's outlet via a connecting pipe, the PLC controller's signal output terminal to the stirring motor's signal input terminal via a data cable, the PLC controller's signal output terminal to the first pneumatic diaphragm pump's signal input terminal via a data cable, the PLC controller's signal output terminal to the second pneumatic diaphragm pump's signal input terminal via a data cable, and the PLC controller's signal output terminal to the motor's signal input terminal via a data cable is one of the technical features of this utility model. The purpose of this design is as follows: the lower part of the coating roller is located inside the coating tank, and a guide roller is provided directly above the coating roller; the lower part of the coating tank has an outlet, and the upper part of the coating tank has an inlet; the upper part of the storage tank has an inlet, and the lower part of the storage tank has an outlet; the outlet of the coating tank is connected to the inlet of the first pneumatic diaphragm pump via a connecting pipe, and the outlet of the first pneumatic diaphragm pump is connected to the inlet of the storage tank via a connecting pipe; the inlet of the coating tank is connected to the outlet of the second pneumatic diaphragm pump via a connecting pipe, and the inlet of the second pneumatic diaphragm pump is connected to the outlet of the storage tank via a connecting pipe; the signal output terminal of the PLC controller is connected to the signal input terminal of the stirring motor via a data cable.

The signal output terminal of the PLC controller is also connected to the signal input terminal of the second pneumatic diaphragm pump via a data cable. The signal output terminal of the PLC controller is connected to the signal input terminal of the motor via a data cable. The PLC controller controls the first pneumatic diaphragm pump to transport the material slurry in the coating tank to the storage tank. At the same time, the PLC controller controls the second pneumatic diaphragm pump to transport the material slurry in the storage tank to the coating tank. The stirring paddle stirs the material slurry in the storage tank. The uniformity of the circulating material slurry is relatively better, thereby ensuring the coating effect of the reciprocating automatic stirring and circulating equipment on the fabric.

[0006] 2. The scraper blade in the scraping assembly is mounted on the frame via a mounting component. The scraper blade's ability to remove excess paste coated on the fabric is the second technical feature of this utility model. The purpose of this design is that the scraper blade in the scraping assembly, mounted on the frame via a mounting component, can remove excess paste coated on the fabric. The scraping assembly's ability to scrape off excess paste improves the uniformity of fabric coating in a reciprocating automatic mixing and circulating equipment. Furthermore, the excess paste scraped off by the scraping assembly falls back into the coating tank, thus improving material utilization.

[0007] 3.

The signal output terminals of the first and second liquid level sensors are respectively connected to the signal input terminal of the PLC controller via data cables; when the material level in the paint tank is at the normal level (between the first and second liquid level sensors), the PLC controller controls... The flow rates of the first and second pneumatic diaphragm pumps are kept at the same level. When the material level in the paint tank is low (the second level sensor generates a signal), the PLC controller increases the flow rate of the second pneumatic diaphragm pump, making it greater than the flow rate of the first pneumatic diaphragm pump, thus distributing the paint in the tank. When the material level in the paint tank is high (the first level sensor generates a signal), the PLC controller keeps the flow rates of the first and second pneumatic diaphragm pumps at the same level, ensuring that the material in the paint tank remains in dynamic balance.

[0008] 4. The design of having a filter device at the inlet of the storage tank and a filter device at the inlet of the paint tank is the fourth technical feature of this utility model. The purpose of this design is that having a filter device at the inlet of the storage tank and a filter device at the inlet of the paint tank can reduce the impurity content in the slurry of the material in the paint tank.
