Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology for mixing tanks, specifically an anti-clogging device for discharging polyurethane resin mixing tanks used in leather. Background Technology

[0002] Polyurethane resin is widely used in the manufacture of synthetic leather due to its excellent abrasion resistance, flexibility and chemical stability. In the leather production process, polyurethane resin needs to be mixed and stored in a mixing tank and then discharged through a discharge pipe. The existing patent application number 201720265540.1 discloses a material discharge anti-clogging device for a polyurethane resin mixing tank for leather. The device is located at the lower end of the discharge port of the mixing tank and includes a material outlet pipe, a valve, and a clearing mechanism. The material outlet pipe is fixedly connected to the discharge port of the mixing tank. The valve is fixedly installed between the material outlet pipe and the discharge port for opening and closing the discharge port of the mixing tank. The clearing mechanism includes a jet pipe with one end embedded in the material outlet pipe and an air pump fixedly connected to the other end of the jet pipe for inputting gas. This solution has a simple structure, reliable implementation, and is economical and convenient, and can effectively prevent the discharge port of the mixing tank from clogging. Existing anti-clogging devices lack temperature control structures during use, leading to the solidification of polyurethane resin inside the discharge shell. Furthermore, the residual polyurethane resin inside the shell cannot be cleaned in a timely manner after discharge, thus affecting subsequent use. To address this, we propose an anti-clogging device for discharging polyurethane resin mixing tanks for leather. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a discharge anti-clogging device for polyurethane resin mixing tanks for leather. By actively feeding with a threaded conveyor rod, guiding and collecting with an inclined plate, pneumatically controlling with an air jet pipe, and precisely controlling the temperature with a heating pipe, a multi-level collaborative anti-clogging mechanism is constructed, which effectively solves the problem of easy solidification and clogging of high-viscosity polyurethane resin. In addition, a cleaning spray pipe is used to spray solvent into the shell for cleaning to ensure normal use in the future. This can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a discharge anti-blocking device for a polyurethane resin mixing tank for leather, comprising a shell and an anti-blocking unit; Housing: A feed shell is provided on the front side of the top surface, and a discharge pipe is provided on the rear side of the bottom surface of the housing. The interior of the housing is connected to the feed shell and the discharge pipe respectively. A cleaning unit is provided on the top surface of the housing. Anti-clogging unit: includes a threaded conveying rod, a frame, a motor, an inclined plate, and a conical groove. The frame is fixed to the bottom surface of the housing, and the motor is mounted on the surface of the frame. The output shaft of the motor is connected to the bottom end of the threaded conveying rod. The threaded conveying rod is located inside the feed housing. The inclined plate is fixed to the bottom surface inside the housing, and the conical groove is located on the front side inside the housing. The system also includes a controller, which is fixed to the surface of the housing. The input terminal of the motor is electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power source.

[0006] Furthermore, the anti-clogging unit also includes a heating chamber, a mounting bracket, a heating tube, a thermostat, bolts, and a mounting slot.

[0007] Furthermore, the anti-clogging unit also includes jet pipes, a water filter, a gas distribution pipe, and a flow control valve. There are two jet pipes, each located in a groove on the rear side of the housing. The air inlets of the two jet pipes are connected to the two air outlets of the gas distribution pipe. A water filter is installed on the outside of the gas distribution pipe. A flow control valve is installed at the air inlet of the gas distribution pipe. The input of the flow control valve is electrically connected to the output of the controller. The flow control valve is connected to an external air pump and adjusts the flow rate of the delivered gas. The gas is blown into the housing through the jet pipes to ensure smooth discharge, while the water filter ensures the gas is dry to prevent moisture in the gas from affecting the polyurethane resin.

[0008] Furthermore, the cleaning unit includes an electric telescopic rod, a placement shell, a cleaning nozzle, a replenishment pipe, a solvent chamber, and a liquid pump. The placement shell is fixed to the top surface of the housing, and the electric telescopic rod is installed on the top surface of the placement shell.

The input ends of the electric telescopic rod and the liquid pump are electrically connected to the output end of the controller. When the liquid pump is started, the solvent inside the solvent chamber is sprayed out through the cleaning nozzle. The electric telescopic rod drives the cleaning nozzle to rise and fall to improve the cleaning effect inside the housing. This can prevent the polyurethane resin remaining inside the housing from solidifying and affecting subsequent use.

[0009] Furthermore, it also includes a temperature sensor, which is fixed inside the housing. The output of the temperature sensor is electrically connected to the input of the controller.
