Technical Field

[0001] The utility model relates to the technical field of EVA black fabric recycling devices, in particular to an EVA black fabric extrusion and shrinkage recycling device. Background Technique

[0002] Because EVA black fabric has strong softness, chemical corrosion resistance and good elasticity, it is widely used in the soles and interior materials of various shoes. Considering that EVA black fabric can be recycled and reused, it is often recycled and transported after reducing the occupied space through an extrusion and shrinkage recycling device.

[0003] The EVA black fabric extrusion and shrinkage recycling device often only realizes the shrinkage treatment of products through a single force-applying extrusion structure. It has the problems of a single extrusion and shrinkage mechanism and poor treatment effect. Moreover, it is not easy to perform heat sealing processing on the product recycling bags that have completed the extrusion and shrinkage treatment, resulting in poor sealing effect of the recycling bags and difficult preservation. Based on this, we propose a new type of EVA black fabric extrusion and shrinkage recycling device to provide better treatment effect. Content of the Utility Model

[0004] The purpose of the utility model is to provide an EVA black fabric extrusion and shrinkage recycling device to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: An EVA black fabric extrusion and shrinkage recycling device, including a frame and a compression force-applying plate. At the bottom end inside the frame, a PVC recycling bag is placed. On one side of the PVC recycling bag, there is a PVC protruding film. A sealing zipper is installed on the PVC recycling bag inside the PVC protruding film. On one side of the frame, a horizontal electric slide rail is welded. A hot pressing base matching the PVC protruding film is slidably connected to the horizontal electric slide rail. One end of the hot pressing base is equipped with an electric telescopic rod, and the output end of the electric telescopic rod is connected to a temperature-controlled electric heating plate. Telescopic cylinders are evenly installed at the top end inside the frame. The compression force-applying plate is connected to the output end of the telescopic cylinder. A vacuum pump is installed on the top of the compression force-applying plate. A monitorable air extraction mechanism is fixed on the vacuum pump. The monitorable air extraction mechanism includes a solenoid valve, an air intake compensation pipe, a pressure gauge and an air extraction pipe component.

[0006] Preferably, fixing screw holes are evenly arranged at the edge of the bottom of the frame, and a rubber buffer layer is vulcanized and connected to the outer side wall of the frame, making it convenient to fix and install the device through screws and improving the stability of the device.

[0007] Preferably, two telescopic cylinders are provided. Assembly inserts are welded to the outer side walls of the telescopic cylinders. Assembly sockets matching the assembly inserts are provided at the top of the frame. Screws are provided between the assembly inserts and the assembly sockets, facilitating the disassembly, installation, and maintenance of the compression force-applying plate and the frame.

[0008] Preferably, the air extraction pipe component is fixed to the input end of the vacuum pump. An air outlet reserved pipe matching the air extraction pipe component is provided at the top of the PVC recycling bag. A manual control valve is installed on the air outlet reserved pipe.

[0009] Preferably, the pressure gauge is installed at one end of the air extraction pipe component. The air inlet compensation pipe is provided on the air extraction pipe component above the pressure gauge. The solenoid valve is installed on the air inlet compensation pipe.

[0010] Preferably, heating wires and temperature sensors are installed inside the temperature-controlled electric hot plate, facilitating the temperature-controlled hot pressing process of the temperature-controlled electric hot plate.

[0011] Preferably, an electric slider is slidably connected to the top end inside the horizontal electric slide rail. The electric slider is welded to the bottom of the electric telescopic rod, facilitating the driving of hot pressing components such as the temperature-controlled electric hot plate to perform horizontal hot pressing movement along the PVC protruding film and achieving the full hot sealing process of the PVC protruding film.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] (1) By installing telescopic cylinders and compression force-applying plates, etc., the EVA black fabric extrusion and shrinkage recycling device optimizes its own performance. On the one hand, two telescopic cylinders are started to drive the compression force-applying plate to press down on the PVC recycling bag for extrusion and shrinkage treatment. On the other hand, when the vacuum pump at the top of the compression force-applying plate is started, the gas inside the PVC recycling bag docked with it can be pumped out through the air extraction pipe component on the monitorable air extraction mechanism, and through the intelligent air pressure monitoring function of the pressure gauge, the automatic vacuum pumping process for the PVC recycling bag containing EVA black fabric can be realized. This can achieve the extrusion and shrinkage treatment of EVA black fabric, reduce the occupied space of EVA black fabric, solve the problem that the existing EVA recycling directly placed in bags occupies a large area and causes inconvenience in transportation, and is convenient for recycling. After one extrusion and shrinkage treatment, the user can quickly relieve the negative pressure inside the air extraction pipe component by closing the vacuum pump, opening the solenoid valve on the air inlet compensation pipe, and closing the manual control valve on the air outlet reserved pipe, facilitating the removal of the PVC recycling bag;

[0014] (2) The EVA black fabric extrusion and shrinkage recycling device is equipped with a temperature-controlled electric heating plate and a hot pressing base. During actual operation, on the one hand, the electric telescopic rod on the hot pressing base is activated to drive the temperature-controlled electric heating plate to move up and down. The temperature-controlled electric heating plate and the hot pressing base can be used to clamp the PVC protruding film on the PVC recycling bag. Then, by using the electric heating wire and temperature sensor installed inside the temperature-controlled electric heating plate, the heating temperature can be regulated to facilitate the temperature-controlled hot pressing and heat sealing treatment of the PVC protruding film by the temperature-controlled electric heating plate. On the other hand, when the horizontal electric slide rail is activated and combined with the corresponding electric slider, it can drive the heat sealing structure composed of the temperature-controlled electric heating plate and the hot pressing base to move horizontally along the PVC protruding film. This can perform the heat sealing treatment of the PVC recycling bag after the extrusion and shrinkage treatment, thereby improving the vacuum sealing protection effect of the PVC recycling bag, preventing air leakage during transportation, and optimizing the recycling, storage, and protection of the EVA black fabric.
