Technical Field

[0001] The utility model relates to the technical field of straw processing equipment, in particular to a cooling device for processing PLA straws. Background Art

[0002] In the production process of PLA straws, an extruder is usually used to heat the PLA raw material to a molten state, and then it is extruded through a mold to form straws. The extruded straws need to be quickly cooled to solidify their shape, which requires the use of a cooling device.

[0003] When the straw is water-cooled in the cooling device, due to the buoyancy of the straw, no matter how long the straw is soaked in water, one side of the straw is always on the water surface, thereby affecting the overall cooling effect of the straw and further affecting the overall quality of the straw.

[0004] To this end, we proposed a PLA straw cooling device that can cool the entire surface to solve the above-mentioned problems. Utility Model Content

By arranging multiple placement tubes 31, it can be suitable for cooling a large number of straws. The straws that need to be cooled are placed inside the placement tube 31 so that the straws are in an upright state. Then, by driving the electric cylinder 12, the entire water cooling mechanism 3 together with the straws inside the placement tube 31 are lowered into the barrel body 2. At this time, the water flow inside the barrel body 2 will flow into the placement tube 31 from all directions through the first cooling groove 311, the second cooling groove 312 and the water flow groove 32 and wrap the straws. In order to prevent the straws from floating, the cylinder 41 at the upper end of the anti-floating mechanism 4 can be driven. The cylinder 41 drives the end cap 42 to descend, which can limit the mechanical energy of the upper end of the straw to prevent the straws from floating, thereby allowing the straws to be fully and quickly water-cooled.

[0022] Furthermore, a support leg 11 is fixedly connected to the lower end surface of the base 1, and electric cylinders 12 are installed on both sides of the lower end surface of the base 1. The output end of the electric cylinder 12 penetrates into the interior of the barrel body 2 and is fixedly connected to the lower surface of the water cooling mechanism 3. A sealing ring is provided at the output end of the electric cylinder 12 that passes through the lower surface of the base 1. This is a prior art and is not elaborated on. The water cooling mechanism 3 and the placement cylinder 31 can be driven to rise and fall by the electric cylinder 12. When the placement cylinder 31 rises out of the barrel body 2, it is convenient to place the straw that needs to be cooled into the placement cylinder 31. After cooling, it can be raised again.

[0023] Furthermore, a control panel 21 is provided on the front surface of the barrel body 2, guide grooves 22 are provided on both sides of the inner surface of the barrel body 2, guide blocks 33 are fixedly connected on both sides of the water cooling mechanism 3, and the guide blocks 33 are slidably connected to the guide grooves 22.

[0024] Furthermore, the circular diameter of the end cover 42 is larger than the circular diameter of the water cooling mechanism 3, and the circular diameter of the end cover 42 is smaller than the circular diameter of the barrel body 2. When in use, the end cover 42 can be lowered into the interior of the barrel body 2, and then the water cooling mechanism 3 can be covered, so that the upper end of the straw inside the placement tube 31 can be supported to prevent the straw from floating.

[0025] Working principle: The utility model is a cooling device for processing PLA straws. When in use, the PLA straws to be cooled are placed in the placement tube 31 so that the straws are in an upright state. The placement tube 31 is provided with a plurality of first cooling grooves 311 and second cooling grooves 312, as well as water-passing grooves 32 at staggered positions with the water-cooling mechanism 3. These structural designs are used to increase the contact area between the water flow and the straws and improve the cooling efficiency. By driving the electric cylinder 12, the water-cooling mechanism 3 together with the placement tube 31 and the straws inside thereof are lowered into the barrel body 2. The barrel body 2 is pre-loaded with water. When the water-cooling mechanism 3 is lowered, the water flows through the first cooling groove 311, the second cooling groove 312 and the water-passing groove. 32 flows into the placement tube 31 and wraps the straw from all sides to achieve rapid cooling. To prevent the straw from floating during the cooling process, the cylinder 41 is started, and the cylinder 41 drives the end cover 42 to descend. The diameter of the end cover 42 is designed to be slightly larger than the diameter of the water cooling mechanism 3, but slightly smaller than the diameter of the barrel body 2, so that it can smoothly descend to the inside of the barrel body 2 and cover the water cooling mechanism 3, thereby limiting the upper end of the straw to prevent the straw from floating. After cooling is completed, the water cooling mechanism 3 and the placement tube 31 are lifted again by the electric cylinder 12 to facilitate the removal of the cooled straw, thereby achieving efficient and rapid cooling of the PLA straw and ensuring the stability and cooling effect of the straw during the cooling process.
