Energy-saving universal type plastic hot cutting machine

Abstract

The invention provides an energy-saving universal type plastic hot cutting machine, and belongs to the technical field of plastic raw material processing equipment. The energy-saving universal type plastic hot cutting machine is characterized in that a gear on a first chromium plating roller is in transmission connection with a shaft roller gear through a transmission gear; a first driving roller is fixed at the upper part of a front rack; a second driving roller is fixed at the upper part of a rear rack; a third chromium plating roller and a fourth chromium plating roller are mounted at the rear part of the front rack; the mounting height of the third chromium plating roller is larger than that of the fourth chromium plating roller. Compared with the prior art, the hot cutting machine is added with the third chromium plating roller and the fourth chromium plating roller, one of the third chromium plating roller and the fourth chromium plating roller is located at the upper part, the other of the third chromium plating roller and the fourth chromium plating roller is located at the oblique lower part, then plastic bypasses the first driving roller and the second driving roller above, by means of the placement positions, the contact area of a plastic strip and a large cooling roller is increased greatly, so that the plastic strip is further cooled, the cooling efficiency is better, and a preform is quickly cooled to the most appropriate temperature for cutting; the energy-saving universal type plastic hot cutting machine can smoothly finish hot cutting working only by a 3.0 KW motor.

Description

technical field [0001] The invention relates to an energy-saving general-purpose plastic hot cutting machine, which belongs to the technical field of plastic raw material processing equipment. Background technique [0002] Existing plastic hot cutting machine, melted plastic raw material is extruded the hot plastic filament of liquid state about 200 ℃ from the extrusion hole and directly passes through the flowing cold water tank and becomes solid plastic filament of 30 ℃~50 ℃. Its disadvantages are: 1. Due to the direct contact with water during the cooling process, the processed plastic particles are very susceptible to moisture, especially in summer, when the air humidity is high, and can only be placed for more than ten days at most, and bubbles will occur inside the particles, resulting in plastic particles It cannot be used normally, so it has to be reprocessed as raw material. Waste of energy, increased production costs. 2. During the water cooling process, the liqu...

Problems solved by technology

Its disadvantages are: 1. Due to the direct contact between the cooling process and water, the processed plastic particles are very susceptible to moisture, especially in summer, when the air humidity is high, and it can only be placed for more than ten days at most, and bubbles will occur inside the particles, resulting in plastic particles It cannot be used normally, so it has to be reprocessed as a raw material

Waste of energy and increase production costs

2. During the water cooling process, the liquid plastic is directly in contact with water, causing serious water pollution, failing to meet environmental protection requirements, and the cooling water cannot be used continuously

3. The particles come out into uneven and irregular cylindrical particles

4. One type of hot cutting machine on the market is only suitable for a single type of plastic pelletizing

[0003] At present, there are also large-scale equipment for processing plastic raw materials on the market. It is also a type of hot cutting machine that is only suitable for a single type of plastic granulation, and the price of the equipment ranges from more than 100,000 yuan to hundreds of thousands of yuan, and it needs a 50KW motor to work normally. Work, high energy consumption, not only increases the purchase cost but also increases the production cost of the enterprise

At the same time, the original old equipment can only be eliminated, resulting in a double waste of resources and funds
