Description

Technical Field

[0001] The utility model relates to the technical field of plastic track raw material mixing, in particular to a mixed plastic track material mixing device. Background Art

[0002] As the name suggests, a plastic track is made from a variety of materials through a melt-blending process. This involves melting and mixing raw materials such as polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers under high temperature and pressure to form a uniform liquid mixture. Subsequently, through a specific construction process, the liquid mixture is laid on the base layer. After cooling and solidification, it forms the track surface with excellent performance. The processing of plastic tracks requires mixing the materials after they are fully blended.

[0003] In the prior art, when mixing the molten plastic track material, stirring is primarily done with a stirring blade or a stirring rod. However, during the stirring process, the stirring blade or the stirring rod pushes the molten material. Furthermore, due to the high temperature of the molten plastic track material, bubbles are easily formed in the molten plastic track material. The air trapped within these bubbles weakens the material's density and strength, thereby affecting the track's elasticity, wear resistance, and aging resistance. Over long-term use, these bubbles may gradually expand, causing damage and cracking on the track surface, shortening its service life. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Example:

[0025] Reference Figures 1-4 The utility model discloses a hybrid plastic track material mixing device, comprising a mixing barrel 1, a bracket 2 connected to the top side of the mixing barrel 1, a positioning ring 3 fixedly connected to the middle of the bracket 2, an exhaust plate 5 connected to the lower part of the positioning ring 3 through a driving member 4, the exhaust plate 5 and the inner side wall of the mixing barrel 1 are slidably connected, the exhaust plate 5 and the mixing barrel 1 are dynamically sealed, and an exhaust member 6 is provided in the exhaust plate 5;

[0026] The exhaust component 6 includes an exhaust groove 7, an upper net 8, a lower net 9, a breathable cloth 10 and a one-way valve 11. The exhaust groove 7 is opened on the bottom side of the exhaust plate 5, the upper net 8 is fixedly installed in the exhaust groove 7, the lower net 9 is arranged below the upper net 8, the lower net 9 is fixedly connected to the inner side wall of the exhaust groove 7, the breathable cloth 10 is arranged between the upper net 8 and the lower net 9, the top side of the breathable cloth 10 is fixedly connected to the bottom side of the upper net 8, the top side of the lower net 9 is fixedly connected to the bottom side of the breathable cloth 10, the outer peripheral side of the breathable cloth 10 is fixedly connected to the inner peripheral side of the exhaust groove 7, the one-way valve 11 is fixedly installed on the top side of the exhaust plate 5 and fixedly connected, and the one-way valve 11 is communicated with the exhaust groove 7.

[0027] In this embodiment, when in use, the raw materials of the plastic runway are placed in the mixing barrel 1, and then the driving member 4 is started. The driving member 4 will drive the exhaust plate 5 to move downward. When the exhaust plate 5 moves downward, it will gradually adhere to the molten material. At this time, the lower clamping net 9 will adhere to the material. In order to prevent the material from blocking the exhaust groove 7, a breathable cloth 10 is used to block it. The breathable cloth 10 can be made of PET non-woven fabric and can be provided with multiple layers. Because the raw materials of the plastic runway are in a viscous state and have a high density when mixed and melted, the breathable cloth 10 can block the material, thereby preventing the material from blocking the exhaust groove 7.

[0028] As the exhaust plate 5 continues to move downward, the exhaust plate 5 continues to squeeze the material, and the internal air will gradually be discharged upward from the breathable cloth 10 during the squeezing, and then the air will be discharged from the position of the one-way valve 11. After the material is squeezed, the bubbles will be squeezed out of the material, thereby reducing the bubbles in the material and improving the quality of the plastic track during paving.

[0029] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the driving member 4 includes a pushing portion and a rotating portion, the pushing portion includes a mounting frame 12, the mounting frame 12 is fixedly mounted on the inner circumference of the positioning ring 3, the top side of the mounting frame 12 is fixedly connected to a hydraulic cylinder 13, the output end of the hydraulic cylinder 13 is connected to a pushing shaft 14, and the bottom end of the pushing shaft 14 is rotatably connected to the top center of the exhaust plate 5.

[0030] In this embodiment, the hydraulic cylinder 13 in the driving member 4 can drive the driving shaft 14 to move up and down. The hydraulic cylinder 13 drives the driving shaft 14 downward, thereby driving the exhaust plate 5 downward, and then squeezing the material to remove bubbles, and then driving the exhaust plate 5 to rotate through the rotating part to facilitate stirring and mixing the material.

[0031] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the rotating portion includes a spiral groove 15, which is opened on the outer peripheral side of the driving shaft 14, and the bottom of the positioning ring 3 is rotatably connected to a swivel 16, and the inner peripheral side of the swivel 16 is connected to a linkage rod 17, and the end of the linkage rod 17 is connected to a rotating ball 18, and the rotating ball 18 is slidably connected to the spiral groove 15, and the bottom side of the swivel 16 is connected to a fixed rod 19, and the bottom end of the fixed rod 19 is slidably connected to a telescopic cavity tube 20, and the bottom end of the telescopic cavity tube 20 is fixedly connected to the top side of the exhaust plate 5.

[0032] In this embodiment, when the spiral groove 15 pushes the shaft 14 to descend, the rotating ball 18 is in sliding connection with the spiral groove 15. The rotating ball 18 will move along the trajectory of the spiral groove 15 when the spiral groove 15 descends, thereby driving the rotating ball 18 to perform circular motion. When the rotating ball 18 performs circular motion, it will also drive the linkage rod 17 to perform circular motion, thereby driving the rotating ring 16 connected to the linkage rod 17 to rotate on the bottom side of the positioning ring 3, thereby driving the exhaust plate 5 to rotate, so as to facilitate the subsequent stirring and mixing of the materials.

[0033] In a further preferred embodiment of the present invention, Figure 2-4As shown, a cross rod 21 is connected to the bottom of the side wall of the exhaust plate 5, the bottom end of the cross rod 21 is connected to a mixing cavity tube 22, the bottom end of the mixing cavity tube 22 is slidably connected to a mixing rod 23, and the mixing rod 23 and the mixing cavity tube 22 are dynamically sealed.

Therefore, when the exhaust plate 5 descends, it will drive the mixing cavity tube 22 and the mixing rod 23 to rotate, thereby driving the materials to be stirred and mixed. The cylinder needs to reciprocate and extend, thereby driving the exhaust plate 5 to move up and down while rotating back and forth, thereby driving the mixing rod 23 and the mixing cavity tube 22 to rotate back and forth, so as to fully mix the materials, so that the materials are repeatedly squeezed and mixed at the same time, so that bubbles can be discharged, thereby improving the mixing quality of the materials.
