Description

Technical Field

[0001] The utility model relates to the field of shaping devices, and particularly to a shaping device for plastic products. Background Technique

[0002] Plastic products are collectively referred to as daily necessities, industrial products, etc. processed mainly with plastics. They include products of all processes such as injection molding and thermoforming with plastics as raw materials. Plastic is a type of synthetic polymer material with plasticity. It, together with synthetic rubber and synthetic fibers, forms the three indispensable synthetic materials in daily life. Specifically, plastic is a material mainly composed of natural or synthetic resin, added with various additives, which can be molded into a certain shape under certain conditions such as temperature and pressure and keep the shape unchanged at normal temperature.

[0003] In the prior art, during the production and processing of plastic pipes as plastic products, a shaping device is often required. After being extruded and formed by an extruder, it is cooled and shaped through the shaping device. Cooling and shaping are achieved by placing the formed plastic pipe in a cooling water tank for soaking. However, during the actual use of the cooling water tank, since fine plastic particles will appear in the cooling water when cooling the plastic pipe, the cooling water cannot be recycled, and after long-term use, the cooling water in the cooling tank will be directly discharged and replaced. This not only wastes water resources, but also as the cooling water in the cooling water tank absorbs heat from the plastic pipe and cools it down, the temperature of the cooling water will rise, thereby reducing the cooling and shaping effect on the plastic pipe.

[0004] The main purpose of the utility model is to provide a shaping device for plastic products, which can effectively solve the problems in the background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Such as Figure 1 - Figure 3As shown in the figure, a shaping device for plastic products includes a cooling box 1. A cooling and shaping mechanism 2 is provided inside the cooling box 1. The cooling and shaping mechanism 2 includes a water tank 4, a spray pipe 7, atomizing nozzles 8, a first pump body 9, and a shunt pipe 12. The water tank 4 is fixedly connected to the rear end of the cooling box 1, and the first pump body 9 is fixedly connected to the top surface of the water tank 4. A connecting pipe 10 is connected between the input end of the first pump body 9 and the water outlet pipe 5 on the left side of the water tank 4, and a delivery pipe 11 is connected between the output end of the first pump body 9 and the shunt pipe 12. The spray pipe 7 is fixedly connected to the front and rear sides of the cooling box 1 and is connected to the shunt pipe 12. A number of atomizing nozzles 8 are fixedly connected to the inner side wall of the spray pipe 7. A filtering and circulating mechanism 3 is further provided at the bottom of the water tank 4. The filtering and circulating mechanism 3 includes a liquid return tank 14, a filtering frame 18, a filter net 19, and a second pump body 22. The liquid return tank 14 and the cooling box 1 are fixedly connected together through a set of symmetric connecting plates 16. The filtering frame 18 is fixedly connected between the connecting plates 16 through the insertion strips 20 on both sides. The filter net 19 is fixedly connected inside the filtering frame 18. The input end of the second pump body 22 is fixedly connected to the drain pipe 15 on the right side of the liquid return tank 14, and a liquid return pipe 23 is connected between the output end of the second pump body 22 and the water inlet pipe 6 on the right side of the water tank 4.

[0021] As Figure 2 shown, the water tank 4 is fixedly installed on the rear end wall of the cooling box 1. The bottom left side of the water tank 4 is fixedly installed with a water outlet pipe 5, and the top right side of the water tank 4 is fixedly installed with a water inlet pipe 6. The water tank 4 is used for storing water and storing the filtered cooling water. The water outlet pipe 5 on the water tank 4 enables the cooling water in the water tank 4 to be pumped out, and the water inlet pipe 6 on the water tank 4 enables the filtered cooling water to enter the water tank 4.

[0022] As Figure 2As shown in the figure, the first pump body 9 is fixedly installed on the right side of the top surface of the water tank 4. A connecting pipe 10 is fixedly installed between the input end of the first pump body 9 and the water outlet pipe 5. A delivery pipe 11 is fixedly installed on the output end of the first pump body 9. A shunt pipe 12 is fixedly installed on the output end of the delivery pipe 11. Spray pipes 7 are fixedly installed on the output ends of both ends of the shunt pipe 12. The spray pipes 7 are fixedly installed on the front and rear side walls of the cooling box 1. A number of atomizing nozzles 8 are fixedly installed on the inner side wall of the spray pipe 7 in a horizontal array and are located inside the cooling box 1. When the plastic pipe after extrusion molding enters the cooling box 1 for cooling, the first pump body 9 will draw out the cooling water in the cooling box 1 from the water outlet pipe 5 through the connecting pipe 10 installed on the input end, and pump the cooling water into the shunt pipe 12 through the delivery pipe 11 installed on the output end. Then, the cooling water is transported into the spray pipes 7 installed on the front and back sides of the cooling box 1 through the shunt pipe 12. Finally, the cooling water is sprayed onto the plastic pipe in the cooling box 1 in an atomized manner through the atomizing nozzles 8 provided on the spray pipes 7. After the atomized cooling water droplets are sprayed on the plastic pipe, under the action of heat exchange, the cooling water droplets will absorb the heat on the plastic pipe and evaporate and gasify after absorbing the heat. In this way, the heat on the plastic pipe is taken away, so as to quickly cool down and shape the plastic pipe by spraying. Compared with the immersion cooling method, it can effectively avoid the problem of too high temperature of the cooling water and ensure the cooling and shaping effect of the plastic pipe;

[0023] As Figure 3 shown, a number of through holes 13 are opened on the bottom surface of the cooling box 1, so that the cooling water sprayed on the cooling box 1 can flow into the lower liquid return box 14 through the through holes 13;

[0024] As Figure 3As shown in the figure, a set of left and right symmetric connecting plates 16 are fixedly installed on the top surface of the water tank 4, and the connecting plates 16 are fixedly installed on the bottom surface of the cooling tank 1. Slots 17 are respectively formed on the opposite side walls of the left and right symmetric connecting plates 16. A filter screen 19 is fixedly installed on the inner bottom surface of the filter frame 18, and insertion strips 20 are respectively fixedly installed on the left and right side walls of the filter frame 18. The insertion strips 20 are inserted into the slots 17. A handle 21 is also fixedly installed on the front end wall of the filter frame 18. By inserting the insertion strips 20 installed on the left and right side walls of the filter frame 18 into the slots 17 formed on the opposite side walls of the left and right symmetric connecting plates 16 installed between the cooling tank 1 and the liquid return tank 14, the filter frame 18 can be installed between the cooling tank 1 and the liquid return tank 14. When the cooling water flowing into the liquid return tank 14 through the through hole 13 passes through the filter frame 18, the filter screen 19 installed on the inner bottom surface of the filter frame 18 can block and filter the plastic particles on the small plastic pipes carried in the cooling water after spraying, so as to avoid the problems of pipeline blockage and inability to be recycled due to excessive small particles in the cooling water. Finally, the cooling water filtered by the filter screen 19 will flow into the liquid return tank 14. At the same time, by regularly pulling out the filter frame 18 from the cooling tank 1 and the liquid return tank 14 through the handle 21, the small particles filtered in the filter frame 18 can be cleaned and recycled, and the filter screen 19 can be cleaned to ensure the filtering effect of the cooling water during long-term use;

[0025] As Figure 3 shown, a drain pipe 15 is fixedly installed at the right bottom of the liquid return tank 14, and the input end of the second pump body 22 is fixedly installed together with the drain pipe 15. A liquid return pipe 23 is fixedly installed between the output end of the second pump body 22 and the water inlet pipe 6. After the filter screen 19 finishes filtering the cooling water and the cooling water flows into the liquid return tank 14, the second pump body 22 is turned on to output the filtered cooling water in the liquid return tank 14 through the drain pipe 15 on the right side of the liquid return tank 14 at the input end, and pump the cooling water into the water tank 4 through the liquid return pipe 23 installed on the output end from the water inlet pipe 6 installed at the right top of the water tank 4, so as to achieve the purpose of recycling the filtered cooling water and avoid wasting water resources and improve the environmental protection of the device during use.

[0026] In summary, the above is only the preferred embodiment of the present invention and is not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present invention, and components therein can be replaced with equivalents, or some technical features can be equivalently replaced. All should be included within the protection scope of the present invention within the spirit and principle of the present invention.
