Description

Technical Field

[0001] This utility model relates to the technical field of spandex bonding agent production equipment, specifically a dissolving device for producing spandex bonding agents. Background Technology

[0002] The main function of spandex cohesive agents is to improve the cohesion between spandex monofilaments. These agents significantly enhance the cohesion between the monofilaments, making the spandex fibers less prone to fraying or breakage during weaving, thereby improving production efficiency and product quality. They also improve the physical properties of spandex fibers. Furthermore, spandex cohesive agents enhance the abrasion resistance of spandex fibers, making them more durable and extending their service life. Spandex cohesive agents are widely used in textiles, clothing, medical, and automotive industries to manufacture various spandex products, such as spandex fabrics, spandex bandages, and spandex seats.

[0003] Spandex binders need to be dissolved with other media during use. After dissolution, the binder can be evenly dispersed in the spandex fibers. Heating is usually required during the dissolution process to increase the dissolution rate. Most existing dissolution devices for spandex binder production have heating coils installed inside the mixing tank to heat the inner wall of the tank and thus heat the spandex binder. Although this design can heat the spandex binder, the heat source only surrounds the inner wall of the mixing tank, requiring prolonged stirring to ensure that the spandex binder inside the tank comes into contact with the inner wall and is heated, thus reducing the dissolution efficiency. Therefore, there is an urgent need for a dissolution device for spandex binder production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a dissolving device for the production of spandex binders, in order to solve the problem mentioned in the background art that the heat source only surrounds the inner wall of the mixing tank, requiring a long period of stirring to allow the spandex binder inside the mixing tank to come into contact with the inner wall of the mixing tank and be heated, thus reducing the dissolving efficiency of the spandex binder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dissolving device for producing spandex bonding agent, comprising a stirring tank, a tank cover, a stirring plate, and a motor, characterized in that: the tank cover is installed above the stirring tank, a rotating shaft is rotatably connected to the inner wall of the tank cover, the motor is installed above the tank cover, and the output shaft of the motor is connected to one end of the rotating shaft;

[0006] The stirring blades are installed on the outside of the rotating shaft. There are multiple stirring blades, and the multiple stirring blades are arranged at equal distances. Multiple protective tubes are connected to the inner wall of the stirring blades, and the multiple protective tubes are arranged at equal distances. A heating tube is installed inside each of the multiple protective tubes. Multiple heat dissipation fins are connected to the outer surface of the protective tubes, and the multiple heat dissipation fins are arranged at equal distances.

[0007] The inner bottom wall of the mixing tank is connected to a support base, and a positioning groove is provided on the inner side of the support base. The end of the rotating shaft away from the motor is rotatably connected to the inside of the positioning groove.

[0008] A discharge pipe is connected to the bottom of the mixing tank, and a valve is installed at one end of the discharge pipe.

[0009] The mixing tank is equipped with three support legs arranged in a circular array.

[0010] An exhaust pipe is connected to the top of the bucket lid, and a filter element is installed at the top of the exhaust pipe.

[0011] A feed pipe is connected to the top of the bucket lid. A one-way valve is installed at the top of the feed pipe. A conveying pipe is connected to the input end of the one-way valve. The conveying pipe has an inclined angle. A hopper is connected to the end of the conveying pipe away from the one-way valve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The present invention relates to a dissolving device for producing spandex binder. Through the cooperation of a heating tube, a protective tube, and heat dissipation fins, heat is generated by the heating tube. The protective tube forms a protective layer around the heating tube, preventing the spandex binder and the mixing medium from contacting the heating tube. As the stirring plate rotates, it moves the protective tube and the heat dissipation fins simultaneously, allowing the heat released by the heating tube to evenly contact the spandex binder and the mixing medium through the protective tube and the heat dissipation fins. This improves the heating efficiency of the spandex binder and the mixing medium, and thus improves the dissolution efficiency of the spandex binder.

[0017] 2. The dissolving device for producing spandex bonding agent of this utility model, through the cooperation between the exhaust pipe and the filter element, guides the steam inside the mixing tank to be discharged through the exhaust pipe, and discharges the steam inside the mixing tank to the outside. The filter element filters the steam discharged to the outside, intercepting harmful substances inside the steam and improving the cleanliness of the steam discharge. Attached Figure Description
