Description

Technical Field

[0001] The utility model relates to the technical field of film molding, and more particularly to an extrusion mechanism for plastic films. Background Art

[0002] The extruder is an important plastic machine. The production and manufacturing of most plastic products can be achieved by extrusion molding. Among them, the extrusion mechanism used in the manufacture of plastic films is an important component. It has many advantages such as high efficiency, high power density, good energy saving, high reliability, and high control precision.

[0003] The shortcomings of the existing technology: However, in the common plastic film extrusion mechanism, the feeding of raw materials is still mainly manual, which greatly slows down the working efficiency of related machines and equipment. In addition, when the extruder is in continuous production for a long time, the rubber material does not flow smoothly in the extruder, causing the rubber material to stay for too long and overheat and burn, resulting in burnt particles and burnt blocks. Especially for products such as plastic films, this seriously affects the production quality of the film. For this reason, we propose an extrusion mechanism for plastic films. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an extrusion mechanism for a plastic film to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: a plastic film extrusion mechanism, comprising a hot melt mechanism, the top of the hot melt mechanism is fixedly connected to a raw material storage tank, the body of the raw material storage tank is fixedly connected to a feeding mechanism, the bottom end of the hot melt mechanism is fixedly connected to a hot melt furnace, one side of the hot melt furnace is fixedly connected to a driving mechanism, one end of the driving mechanism is fixedly connected to a driving shaft, the shaft body of the driving shaft is fixedly connected to a temperature difference adjustment component, one end of the temperature difference adjustment component is fixedly connected to a plastic guide tube, and one end of the plastic guide tube is fixedly connected to the extrusion mechanism.

[0006] Preferably, a feed pipe is fixedly connected to the top surface of the hot melting furnace, a top end of the feed pipe is fixedly connected to a raw material storage tank, and a reserve detector is fixedly connected to one side of the raw material storage tank.

[0007] Preferably, one end of the feeding mechanism is fixedly connected to a feeding pipe, one end of the feeding pipe is fixedly connected to a pneumatic valve, one side of the pneumatic valve is fixedly connected to a signal meter, one end of the pneumatic valve is connected to the feeding pipe, and the other end of the feeding pipe is fixedly connected to a funnel swallowing tube.

[0008] Preferably, a support base is provided at the bottom end of the driving mechanism, a driving motor is fixedly connected to one side of the support base, and the middle of the support base is fixedly connected to the driving shaft.

[0009] Preferably, one end of the temperature difference regulating component is fixedly connected to a plurality of material dividing plates, the middle of the temperature difference regulating component is fixedly connected to a guide column, a plurality of guide holes are opened on the guide column, the guide holes opened at one end of the guide column are fixedly connected to a cluster tube, and one end of the cluster tube is fixedly connected to a plastic guide tube.

[0010] Preferably, the extrusion mechanism includes an extruder base plate, an extrusion cavity is provided inside the extruder base plate, an exhaust ring is provided on the outside of the extrusion cavity, an exhaust cavity is provided inside the extrusion cavity, and an air pump is provided at the bottom of the exhaust cavity.

[0011] The technical effects and advantages of the utility model.

[0012] 1. The utility model is provided with a feeding mechanism through a hot melt mechanism, and a reserve detector which can detect the stock of raw materials in the tank is arranged on the body of the raw material storage tank. When the raw materials are reduced to a certain amount, the reserve detector sends a signal to the signal meter on the pneumatic valve, and the signal meter is connected to the switch of the pneumatic valve. When the signal is received, the pneumatic valve starts, and is connected to the total storage bin through the feed pipe, and uses a huge suction force to suck the raw materials into the tank until the storage amount in the tank reaches the safety index. The reserve detector sends a signal to the signal meter again, and the pneumatic valve stops working after receiving the signal meter, thereby eliminating the process of manually feeding raw materials at a fixed time, reducing the workload of the staff, and improving the overall work efficiency.

[0013] 2. The utility model is provided with a temperature difference regulating component through the hot melt mechanism. After the raw materials enter the hot melt furnace, they first enter the dividing partition to separate the raw materials into multiple parts at one time, accelerate the melting efficiency of the raw materials, and then flow into the guide hole on the guide column during the rotation. When entering the guide hole, due to the thickening of the inner and outer barriers, the temperature is lower than that on the dividing partition just entering the hot melt furnace, which alleviates the coke particles and coke blocks caused by too long burning. Then they flow into the cluster tube again and enter the plastic guide tube, further alleviating the overheating of the molten raw materials, effectively reducing the coke particles and coke blocks caused by too long residence time of the rubber material, and improving the quality of plastic products.

[0023] The reserve detector 104 is used to detect the storage amount of raw materials inside the raw material storage tank 103, so as to facilitate the addition of raw materials when the storage amount is insufficient.
