Problems solved by technology

When feeding, it usually depends on the weight of the plastic material itself to drop to the feeding port of the screw, and the feeding pressure is relatively small. When the scrap and recycled materials are used as raw materials, the feeding is uneven or sometimes not feeding due to insufficie

Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further described, see figure 1 As shown, it is a TPU film blowing machine equipped with a side-propelled feeder, which includes a two-layer co-extrusion film blowing machine channel 1, a material inlet 2, and a hopper 3. The top of the film blowing machine channel 1 and the The feeding port 2 is connected, and the feeding port 2 is connected with a feeder 4 that increases the feeding pressure. The hopper 3 is connected with the feeding machine 4. The feeding machine 4 includes a horizontally arranged push screw 5 and a motor that drives the push screw 5 6. One end of the push screw 5 is connected to one side of the feed port 2, the other end is connected to the motor 6, and the bottom of the hopper 3 is connected to the push screw 5. The motor 6 is connected with the push screw 5 through a reducer 7 . The feeder 4 can be composed of a single screw or a double screw, and the feeder 4 can also...

Abstract

The invention relates to the technical field of the film blowing machine, in particular to a TPU film blowing machine provided with an additional feeding machine, which comprises a material passage ofthe film blowing machine, a material feeding opening and a material hopper, wherein the top of the material passage of the film blowing machine is communicated with the material feeding opening, thematerial feeding opening is connected with the feeding machine which increases the material feeding pressure, the material hopper is communicated with the feeding machine, and the feeding machine comprises a push screw rod and a motor. The invention increases the material feeding pressure by the feeding machine, scraps and reclaimed materials can be used as raw materials for recycling, the pressure is uniform and stable, more TPU pulverized materials can be added, the quality and the property of a product are not influenced, the use of the raw materials is reduced, the use rate of the raw materials can reach more than 99.5%, and the cost is lowered.

Description

Technical field: [0001] The invention relates to the technical field of film blowing machines, in particular to a TPU film blowing machine equipped with a feeder. Background technique: [0002] TPU (Thermoplastic polyurethanes) is a thermoplastic elastomer plastic, which is a plastic material that can be softened or changed repeatedly at a certain temperature, but can remain unchanged at room temperature. It is an emerging environmental protection product in China and is the best alternative to PVC. The best product can be decomposed underground and is non-toxic and harmless to the environment. It is widely used in shoemaking, pipes, films... and other industries. TPU film is made on the basis of TPU pellets by calendering, casting, film blowing, coating and other processes. At present, it is widely used in sports shoes: trademark decoration on soles and uppers, air bags, air cushions, oil bags, etc. [0003] At present, the machines that produce TPU film in China are main...
