Description

Technical Field

[0001] The utility model relates to the field of battery box structures, in particular to a heat dissipation device for MPP tube production. Background Art

[0002] MPP uses modified polypropylene as the main raw material. It is a construction project that does not require a large amount of dredging, digging, or damaging the road surface. It can lay pipelines and cables in special areas such as roads, railways, buildings, and riverbeds. Compared with the traditional "trench-digging and pipe-laying method", trenchless power pipe engineering is more in line with current environmental protection requirements, eliminating dust and traffic congestion caused by traditional construction. This technology can also lay pipelines in some areas where excavation operations cannot be carried out.

[0003] MPP pipe production is generally processed by high-temperature melt extrusion, that is, the raw materials are heated at high temperature, then formed from one end of the extruder, and pulled out through the traction equipment. In this process, in order to ensure the rapid molding of the finished product, heat dissipation equipment is set up on the production line. Commonly used heat dissipation devices all use spray heat dissipation. Since the single length of MPP pipe is relatively large, when spraying heat dissipation on it, the corresponding heat dissipation nozzles are required to be large. Utility Model Content

[0014] Beneficial effects of the utility model:

[0015] (1) The utility model discloses a heat dissipation device for producing MPP pipes. The utility model is provided with a driving part and other components, which controls the driving motor to enter a working state, drives the connecting shaft to rotate through the output shaft, drives the swing arm to rotate through the connecting shaft, and drives the guide block to rotate together after the swing arm rotates. The guide block slides vertically in the guide hole synchronously during the co-rotation process, and the guide block applies a horizontal extrusion force to the guide hole.

Under the action of the thrust, the straight rod moves to a lateral position, pulling the ball rod to drive the hollow ball head rod and the heat dissipation nozzle to deflect laterally, thereby further increasing the spray heat dissipation angle and further improving the heat dissipation effect. The movable frame synchronously drives the cleaning ring and the dry brush head to reciprocate, and the dry brush head is used to wipe the outer wall of the MPP pipe to wipe off the water stains remaining on the surface during heat dissipation.

A heat dissipation pipe 3 is arranged inside the shell 2. The water inlet of the heat dissipation pipe 3 is connected to the external pipe. The outer wall of the heat dissipation pipe 3 is evenly spaced with water outlet ends, and each water outlet end is connected to a heat dissipation nozzle 5 through a hollow ball head rod 4. When the external pipe control valve is opened, water for heat dissipation will be sprayed out from each heat dissipation nozzle 5 along the heat dissipation pipe 3. The sprayed water acts on the outer wall of the MPP pipe to achieve the heat dissipation effect. The outer wall of the hollow ball head rod 4 is symmetrically provided with semicircular grooves 41. A driving motor 6 is mounted on the outer wall of the shell 2. A driving unit 7 is mounted on the output end of the driving motor 6.

[0027] The driving part 7 comprises a guide rail 71, a slider 72, a guide hole 73, a guide block 74, a swing arm 75, a connecting shaft 76, a collar 77 and a driving frame 78. The guide rail 71 is mounted on the inner wall of the housing 2. A slider 72 is slidably mounted on the guide rail 71. A guide hole 73 is provided inside the slider 72. A guide block 74 is slidably mounted on the inner wall of the guide hole 73. A swing arm 75 is rotatably connected to the side wall of the guide block 74 at a central position. A connecting shaft 76 is provided on the side wall of the swing arm 75, and the connecting shaft 76 is connected to the output shaft of the driving motor 6 through a coupling. A collar 77 is welded on the inner wall of the slider 72, and a driving frame 78 is welded on the side wall of the collar 77. Vertical holes 781 are equidistantly provided inside the driving frame 78. A ball rod 782 is horizontally inserted in each vertical hole 781. The ball head of the ball rod 782 is located in the semicircular groove 41. When working, the driving motor is controlled 6 enters the working state, the output shaft drives the connecting shaft 76 to rotate, and the connecting shaft 76 drives the swing arm 75 to rotate. After the swing arm 75 rotates, it drives the guide block 74 to rotate together. The guide block 74 synchronously slides vertically in the guide hole 73 during the co-rotation process. The guide block 74 applies a horizontal extrusion force to the guide hole 73, and the extrusion force drives the slider 72 to reciprocate on the guide rail 71, that is, the slider 72 drives the collar 77 and the driving frame 78 to reciprocate. During the movement of the driving frame 78, the ball rod 782 is driven to move synchronously. The ball rod 782 applies a thrust to the hollow ball head rod 4 while sliding in the semicircular groove 41 and the vertical hole 781. The hollow ball head rod 4 is deflected under the action of the thrust, thereby increasing the spraying area of ​​the heat dissipation nozzle 5, that is, in the characteristic area, the heat dissipation operation of the MPP tube can be achieved by arranging a smaller number of heat dissipation nozzles 5.

[0028] See also Figure 1-5A support spring 783 and a positioning rod 784 are respectively installed between the two ball rods 782 and the driving frame 78 in the same vertical plane. A straight rod 785 is welded to the top of the tail of the ball rod 782 on one side of the positioning rod 784. Rectangular plates 8 are arranged at equal intervals on both sides of the driving frame 78. The rectangular plates 8 are fixedly connected to the outer wall of the heat dissipation pipe 3 through round rods. The side walls of the rectangular plates 8 are installed with triangular plates 81 through support rods, and the triangular plates 81 are rotatable relative to the support rods. A torsion spring is installed at the connection between the two. In the initial state, the torsion spring pushes the triangular plates 81 to be located as shown in FIG. Figure 3 The position shown is parallel to the rectangular plate 8. When working, the driving frame 78 drives the straight rod 785 to contact the triangular plate 81 and slide along its inclined surface during the movement, so that the inclined surface of the triangular plate 81 generates a thrust on the straight rod 785. Under the action of the thrust, the straight rod 785 moves to a lateral position, pulling the ball rod 782 to drive the hollow ball head rod 4 and the heat dissipation nozzle 5 to deflect laterally, thereby further increasing the spray heat dissipation angle. At the same time, during the lateral movement of the straight rod 785, the support spring 783 is compressed and has a rebound force. When the triangular plate 81 is separated from the straight rod 785, the rebound force generated by the compression of the support spring 783 drives the ball rod 782 to reset. When the driving frame 78 is reset, it squeezes the triangular plate 81 along Figure 3 Deflection shown.

[0029] See 1- Figure 5 The support springs 783 and the positioning rods 784 on both sides of the two adjacent heat dissipation nozzles 5 are arranged in opposite positions, that is, the deflection angles of the adjacent heat dissipation nozzles 5 under the action of the triangular plate 81 are just opposite, which further increases the spraying and heat dissipation area of ​​the heat dissipation nozzle 5 and further improves the heat dissipation effect.
