Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing equipment technology, specifically to a water-cooled shaping equipment for producing reinforced PP plastic. Background Technology
[0002] Reinforced PP plastic is a composite material whose mechanical properties are improved by adding reinforcing materials (such as glass fiber, polypropylene fiber, etc.) or by using chemical modification methods. Its core is to improve the tensile strength, impact resistance, and other properties of polypropylene through external reinforcement or chemical modification to meet higher strength requirements. During the production process of reinforced PP plastic, the reinforced PP plastic extruded from the extruder head is at a high temperature and needs to be cooled before entering the pelletizing system. A commonly used cooling device is a cooling water tank. The plastic line runs from one end of the cooling water tank to the other, exchanging heat with the cooling water to lower its temperature.

[0031] This utility model provides a technical solution:
[0032] Please see Figures 1-5 A water-cooled shaping device for producing reinforced PP plastic includes a cold water tank 1, a winding assembly 2 and a guiding assembly 3. A drain pipe 11 is provided at the bottom of one side of the cold water tank 1, and a valve is installed on the drain pipe 11. By setting the drain pipe 11, the valve can be opened to drain the used water in the cold water tank 1.
[0033] Specifically, the winding assembly 2 is located at one end of the cold water tank 1. The winding assembly 2 includes a third bracket 21 fixedly installed at one end of the cold water tank 1. A motor 22 is fixedly installed on one side of the third bracket 21. The output end of the motor 22 is fixedly connected to a rotating shaft. Multiple detachable drums 23 are fixedly mounted on the rotating shaft. By setting up the winding assembly 2, when cooling the PP plastic line, one end of the extruded PP plastic line is pulled through the top of the cold water tank 1 and wound onto the corresponding drum 23. Then, the motor 22 can be started to drive the rotating shaft to rotate, so that the rotating shaft drives the drum 23 to wind up the PP plastic line.
[0034] Specifically, the guide assembly 3 includes a first bracket 31 fixedly installed at both ends of the cold water tank 1 and a first guide roller 32 rotatably installed on the first bracket 31. A fixing frame 33 is fixedly installed on the top of the cold water tank 1, and a cylinder 34 is fixedly installed on the top of the fixing frame 33. A support plate 35 is fixedly connected to the lower end of the cylinder 34. Two second brackets 36 are spaced apart at the bottom of the support plate 35, and a second guide roller 37 is rotatably installed at the bottom of the second brackets 36. Multiple spaced guide grooves 38 are opened on the surfaces of the first guide roller 32 and the second guide roller 37. By setting the guide assembly 3, when the PP plastic is pulled... When the PP plastic line passes over the cold water tank 1, it passes over the first guide roller 32 and under the second guide roller 37. When winding the PP plastic line, the cylinder 34 is activated to drive the support plate 35 to descend, which in turn drives the second guide roller 37 to descend. The second guide roller 37 presses the PP plastic line into the cold water tank 1. The PP plastic line passing through both ends of the cold water tank 1 will be placed on the first guide roller 32 and enter the corresponding guide groove 38. During the winding process, the PP plastic line can be guided to avoid tangling and improve the molding effect.
[0035] Guide rods 39 are fixedly installed at the four corners of the top of the support plate 35. The guide rods 39 slide through to the top of the fixing frame 33. By setting the guide rods 39, the support plate 35 can be guided and the stability of the support plate 35 can be improved.
[0036] Furthermore, a spring 310 is fixedly installed between the second bracket 36 and the support plate 35. The spring 310 is sleeved on the limiting rod 311. The lower end of the limiting rod 311 is fixedly connected to the second bracket 36, and the upper end of the limiting rod 311 slides through to the top of the support plate 35. The top of the fixing frame 33 is provided with a clearance opening 312. By setting the spring 310 and the limiting rod 311, a downward elastic force can be applied to the second bracket 36, so that the second bracket 36 drives the second guide roller 37 to apply elastic force to the PP plastic line, so that the PP plastic line maintains a certain tension during the guiding process, which can prevent the PP plastic line from loosening when cooling and further improve the molding effect.
[0037] The working principle of this utility model is as follows:
[0038] First, when cooling the PP plastic line, one end of the extruded PP plastic line is pulled through the cold water tank 1 and wound onto the corresponding roll 23. When the PP plastic line is pulled over the cold water tank 1, it passes over the first guide roller 32 and under the second guide roller 37.
[0039] The starting cylinder 34 drives the support plate 35 to descend, which in turn drives the second guide roller 37 to descend. The second guide roller 37 presses the PP plastic line into the cold water tank 1. The PP plastic line passing through both ends of the cold water tank 1 will be placed on the first guide roller 32 and enter the corresponding guide groove 38. Then, the motor 22 can be started to drive the rotating shaft to rotate, which drives the drum 23 to wind up the PP plastic line. During the winding process, the PP plastic line can be guided to avoid tangling and improve the molding effect.
[0040] To further prevent the PP plastic line from loosening during cooling, a spring 310 and a limiting rod 311 are provided. These can apply a downward elastic force to the second bracket 36, causing the second bracket 36 to drive the second guide roller 37 to apply elastic force to the PP plastic line. This keeps the PP plastic line in a certain taut state during the guiding process, preventing it from loosening during cooling and further improving the forming effect.
[0041] In summary, this water-cooled molding equipment for producing reinforced PP plastic, by setting up a guide component 3, allows the PP plastic line to pass over the first guide roller 32 and under the second guide roller 37 when pulled over the cold water tank 1. When winding the PP plastic line, the cylinder 34 is activated to drive the support plate 35 to descend, which in turn drives the second guide roller 37 to descend, pressing the PP plastic line into the cold water tank 1. The PP plastic line passing through both ends of the cold water tank 1 will be placed on the first guide roller 32 and enter the corresponding guide groove 38. During the winding process, the PP plastic line can be guided to avoid tangling and improve the molding effect.
[0042] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
