Description

Technical Field

[0001] This utility model relates to the field of biodegradable material processing technology, specifically to an extrusion cooling device for biodegradable materials. Background Technology

[0002] With social development and the increasing standard of living, people's demand for plastic products is growing. After use, plastic products become plastic waste. Ordinary plastic waste cannot degrade quickly and needs to be incinerated or landfilled for disposal. However, both incineration and landfilling cause environmental pollution. To solve environmental problems, biodegradable plastics have begun to be used. Biodegradable plastic materials are a type of biodegradable plastic. Due to their fast degradation and strong environmental protection capabilities, they are widely used in many industries such as packaging, catering, and textiles.

[0003] When biodegradable materials are manufactured, they need to be heated to melt them, and then extruded and shaped through an extruder. At this time, the product temperature is high and it is prone to deformation, so it needs to be cooled in time to fix its shape. This requires a cooling device. Among the common cooling methods, cold water pipes are installed around the extrusion tube for heat exchange. Water cooling exchanges heat through a medium. However, the heat transfer efficiency between the cooling water and the material is low, resulting in low cooling efficiency. The cooling water provided by general cooling equipment is mostly at a constant temperature, cooling the product at the lowest possible temperature, causing rapid cooling of the material. For dense materials, this sudden heating and cooling can easily leave residual internal stress. If the material strength is insufficient, cracking may occur during use, leading to product damage.

[0004] Based on this, an extrusion cooling device for biodegradable materials is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0032] In one embodiment, such as Figure 3 As shown, the circulating water supply component 300 includes a water tank 301 and a pumping component. The water tank 301 is located on the upper end of the base 100, and the pumping component is located on one side of the water tank 301. The side wall of the water tank 301 is provided with an installation hole 302. The water tank 301 is provided with a pumping area 304 and a water collection area 305. A filter plate 303 is provided between the pumping area 304 and the water collection area 305. In use, water is pumped from the pumping area 304 by the pumping component and transported to the spraying component 500.

In use, the fan 605 blows air into the annular air duct 601, so that the air blows towards the product through the air outlets 604, thereby blowing away the water stains on the surface of the product towards the water tank 301.

[0039] In one embodiment, such as Figure 7 As shown, the support roller assembly 700 includes a base 701, which is slidably mounted in a guide groove 103 on the base 100 via a second guide block 702 at its lower end. A movable seat 703 is slidably disposed inside the base 701. A telescopic rod 704 is provided at the lower end of the movable seat 703, and a support roller 705 is rotatably connected to the upper end of the movable seat 703. In use, the height of the support roller 705 is adjusted according to the product size by means of the telescopic rod 704, so that the product is in the middle position of the spray assembly 500, thereby ensuring that the cooling water evenly covers the product surface.

[0040] The above embodiment discloses an extrusion cooling device for biodegradable materials. In use, multiple sets of independent circulating water cooling modules 200 and support roller assemblies 700 are first installed on the base 100 as needed. Then, the cooling water in the water tank 301 is heated by the heating pipe 402 to maintain a certain temperature in the cooling water in the water tank 301 of the independent circulating water cooling module 200. Then, the freshly produced products are passed through the independent circulating water cooling module 200 in sequence. According to the product size, the height of the support roller 705 is adjusted by the telescopic rod 704 so that the product is in the middle position of the spray assembly 500. At the same time, the water pump 307 draws cooling water from the water pumping area 304 and then delivers it to the spray assembly 500 through the diversion pipe 309, so that it is sprayed onto the product through the nozzle 510. At the same time, the reverse thrust generated by the spraying of cooling water causes the rotating seat 502 to rotate around the water supply seat 501, thereby driving the spray pipe 503 to rotate together, so that the cooling water covers the product surface more evenly.
