Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel cord production technology, specifically to a concentration switching device for a solution tank used for coating steel wire with coumar. Background Technology
[0002] Cumar is a chemical agent used to enhance the adhesion between materials, often in resin form. In industrial applications, Cumar resin and its derivatives have a variety of uses, particularly in the production of steel cord, where it is used as an adhesion promoter between metal and rubber.
[0003] In industrial applications, "coating with coumarin" refers to the process of applying a coumarin solution to the surface of steel wire. This solution is typically made by mixing gasoline and acetone in a specific ratio and stirring thoroughly. The main purpose of coumarin coating is to improve the adhesion strength between the steel wire and the rubber, while also providing rust protection for the steel wire and improving its winding performance during the take-up process, resulting in a smoother and easier-to-handle wire.
[0004] Existing couma coating equipment includes a solution tank for holding the couma solution. During the coating process, a metal wire quickly passes through a cotton rope soaked in the couma solution, and the couma solution in the tank is coated onto the surface of the wire using the adsorption principle of the cotton rope. However, due to the single type of couma solution tank, when it is necessary to change to a different concentration of couma solution, the production line must be stopped for solution replacement. This solution replacement is time-consuming, reducing actual production time. After each solution replacement, restarting the equipment requires a series of checks and adjustments, which seriously affects production efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a solution tank concentration switching device for coating coumarin with steel wire, which can switch the solution tank without stopping the production line, meet the coating requirements of different concentrations of coumarin solution, and has a fast switching speed, reducing the time consumed by changing the solution and improving production efficiency.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a concentration switching device for a solution tank for coating coumar on steel wire, comprising a support, wherein at least two sets of solution tanks are provided on the support, and a storage tank corresponding to each set of solution tanks is provided below the solution tanks, and a pump connected to the storage tank is provided above the storage tank, wherein the outlet end of the pump is connected to the solution tank through a delivery pipe, and a return pipe communicating with the storage tank is provided on the solution tank.
[0007] A further improvement of this utility model is that the support is provided with a protective cover, the solution tank is located inside the protective cover, and the protective cover is provided with an opening to facilitate the movement of the steel wire.
[0008] A further improvement of this utility model is that the protective cover is provided with a protective groove, and the protective groove is provided with several partitions. The partitions divide the protective groove into several sub-grooves corresponding to the number of solution tank groups, and each group of solution tanks is set in its corresponding sub-grooves.
[0009] A further improvement of this utility model is that the protective groove is provided with a sealed connection port that facilitates the passage of the infusion tube and the return tube.
[0010] A further improvement of this invention is that the solution tank is provided in two sets.
[0011] A further improvement of this utility model is that each set of solution tanks includes two sub-solution tanks spaced apart, the outlet end of the pump is provided with a three-way connector, the three-way connector is connected to the two sub-solution tanks through two delivery pipes, and the storage tank is provided with two return pipes that communicate with the two sub-solution tanks.
[0012] A further improvement of this invention is that the pump is a diaphragm pump.
[0013] The beneficial effects of this utility model are as follows:
[0014] This invention utilizes at least two sets of solution tanks, employing a pump, delivery pipe, and return pipe to circulate the couma solution within the tanks. When a concentration switch is required, the pump corresponding to the currently used solution tank is first shut off, preventing replenishment and causing continuous backflow until all solution is discharged. Then, the pump corresponding to the desired concentration solution tank is activated, injecting the couma solution of the required concentration into the other solution tank. A steel wire applies couma solution via a cotton rope in the other solution tank. This allows for seamless switching between solution tanks without interrupting production, enabling the application of different couma solution concentrations. The fast switching speed reduces solution change time and improves production efficiency.
[0015] This invention achieves the circulation of coumarin solution in the solution tank through a pump, delivery pipe, and return pipe, which keeps the coumarin solution in the storage tank flowing, ensures uniform distribution of coumarin solution components in the tank, prevents the formation of precipitates, and maintains the stability of the solution.
[0016] This invention sets up multiple independent solution tanks, each of which can be configured with a Kuma solution of different concentrations to meet diverse production needs and improve the flexibility of the Kuma treatment process.
[0017] In this invention, steel wires can be passed sequentially through various concentrations of coumarin solution and coated multiple times to produce better products, as required. Attached Figure Description

[0023] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. Example
[0024] Combination Figures 1-4 It is known that a concentration switching device for a steel wire coating solution tank includes a support 1, on which at least two sets of solution tanks 2 are provided. Below each solution tank 2 is a storage tank 3 corresponding to one of the solution tanks 2. Above each storage tank 3 is a pump 4 connected to it. The outlet of the pump 4 is connected to the solution tank 2 via a delivery pipe 5. The solution tank 2 is provided with a return pipe 6 connected to the storage tank 3. The inlet of the pump 4 is connected to the storage tank 3 via a pipe.
[0025] The solution tank 2 is also equipped with several cotton ropes corresponding one-to-one with the number of steel wires. All cotton ropes in the solution tank 2 corresponding to a single steel wire are spaced apart along the direction of the steel wire's movement, allowing the steel wire to pass through all the corresponding cotton ropes in the solution tank 2 during movement. The cotton ropes and their fixing structure are conventional structures used in existing technology for coumarin coating. Multiple steel wires in rows on the production line move at a uniform speed through the multiple cotton ropes in the solution tank 2, utilizing the adsorption principle of the cotton ropes to coat the steel wire surface with the coumarin solution from the solution tank.
[0026] Preferably, the upper end of the solution tank 2 is provided with a horizontal plate, and the horizontal plate has a plurality of fixing holes for fixing the cotton rope. One end of the cotton rope is immersed in the solution tank 2, and the other end is located above the horizontal plate for contact with the steel wire. Preferably, a wire divider is provided on one side of the solution tank along its length to ensure that multiple steel wires can move at intervals.
[0027] A protective cover 7 is provided on the support 1, and the solution tank 2 is located inside the protective cover 7. The protective cover 7 has an opening to facilitate the movement of the steel wire. Preferably, a sensor-operated fire extinguisher is provided on the inner top surface of the protective cover.
[0028] The protective cover 7 contains a protective trough 8, which is further divided into several partitions 9. These partitions 9 divide the protective trough 8 into several sub-troughs corresponding to the number of solution tanks 2. Each set of solution tanks 2 is located within its corresponding sub-trough. The protective trough 8 allows for the collection of solution dripping from the steel wire, preventing it from contaminating the site.
[0029] In this invention, when switching between solution tanks 2 of different concentrations, a certain length of steel wire coated by both the new and old concentration solution tanks 2 will be generated. When there are restrictions on this in the order requirements, the steel wire can be cut off when winding the steel wire.
[0030] Preferably, the pump 4 is a diaphragm pump. The protective tank 8 is provided with a sealed connection port to facilitate the passage of the infusion pipe 5 and the return pipe 6.
[0031] Each set of solution tanks 2 includes two spaced sub-solution tanks 11. The outlet end of the pump 4 is equipped with a three-way connector, which is connected to the two sub-solution tanks 9 via two delivery pipes 5. The storage tank 3 is equipped with two return pipes 6 that communicate with the two sub-solution tanks 11. The cotton rope makes fuller contact with the steel wire through two sub-solution tanks compared to a single sub-solution tank. Preferably, there are two sets of solution tanks 2.
[0032] The working principle of the couma solution concentration switching device for steel wire coating provided by the utility model is as follows: When it is necessary to switch the concentration of the couma solution, first turn off the pump 4 corresponding to the solution tank 2 that is currently in use, so that the solution in the solution tank 2 is not replenished, and the couma solution in it continuously flows back to the storage tank 3 until all the solution in the solution tank 2 is discharged. Then, turn on the pump 4 corresponding to the solution tank 2 of the required concentration, and inject the couma solution of the required concentration into the solution tank 2 of the required concentration. The steel wire is coated with couma through the cotton rope on the solution tank 2. It can realize the switching of solution tanks without stopping the production line, realize the coating requirements of different concentrations of couma solution, the switching speed is fast, the liquid replacement consumption time is reduced, and the production efficiency is improved.
