[0018] See also Figure 1-4The utility model provides a technical solution: a drying material energy-saving device for an injection molding machine, comprising a drying material barrel 1, a feeding port is arranged on one side of the top of the drying material barrel 1, a blower 2 is arranged on one side of the outside of the drying material barrel 1, a ventilation pipe 3 is connected between the blower 2 and the bottom end of the drying material barrel 1, a control box is also arranged between the blower 2 and the ventilation pipe 3, a motor 4 is installed on the outside of the top of the drying material barrel 1 by bolts, a rotating rod 5 is arranged at the center of the inside of the drying material barrel 1, the output end of the motor 4 passes through the inside of the drying material barrel 1 and is connected to the top of the rotating rod 5 through a coupling, dispersion seats 6 are arranged on the outside of the upper and lower ends of the rotating rod 5, a vertical sleeve 7 is fixed at the center of the dispersion seat 6, the vertical sleeve 7 is slidably sleeved on the outside of the rotating rod 5, a vibration component is arranged between the dispersion seats 6, and the outside of the bottom end of the rotating rod 5 is arranged There is a conical seat 15. When the blower 2 of this structure is started to transport wind from the ventilation pipe 3 to the inside of the drying barrel 1 to dry the added injection molding granular raw materials, the motor 4 can drive the rotating rod 5 to rotate. When the rotating rod 5 rotates, it can synchronously drive the two dispersion seats 6 and the conical seat 15 to rotate. When the dispersion seat 6 and the conical seat 15 rotate, they can evenly disperse the granular raw materials added to the inside of the drying barrel 1, and the two dispersion seats 6 can also generate a certain amplitude of up and down vibration driven by the vibration component to further ensure the effect of the dispersion activity of the granular raw materials, so that the blower 2 can blow and dry the granular raw materials inside the drying barrel 1 more evenly, so as to speed up the drying speed and avoid the granular raw materials from stacking on each other inside the drying barrel 1. Together, there will be problems of uneven baking and prolonged baking time, thereby reducing the energy consumption of the baking process, and having higher energy saving performance. The vibration components between the dispersion seats 6 include a vertical axis 9, a horizontal axis 10, a movable sleeve 11 and a small vibrator 12. The movable sleeve 11 is arranged on the outside of the middle of the rotating rod 5. The small vibrator 12 is fixed to the bottom of the front end of the movable sleeve 11 by means of a support block and bolts. The horizontal axis 10 is symmetrically welded and fixed on both sides of the movable sleeve 11. The vertical axis 9 is fixed to the outer end of the horizontal axis 10 to form a vertical distribution. The connection between the horizontal axis 10 and the vertical axis 9 is located in the middle of the vertical axis 9, and the upper and lower sides of the vertical axis 9 are respectively welded and fixed to the outer walls of one side corresponding to the upper and lower dispersion seats 6. When the small vibrator 12 of this structure is driven, it will directly act on the movable sleeve 11 in the rotating rod 5 When the movable sleeve 11 moves, it will synchronously link the two dispersion seats 6 through the horizontal axis 10 and the vertical axis 9. When the dispersion seat 6 is linked, a certain amplitude of vibration can be achieved inside the drying barrel 1, so that the granular raw materials can be dispersed more effectively inside the dispersion seat 6, and the material falling is also smoother. The bottom end of the vertical sleeve 7 is provided with a support ring 14 fixedly sleeved on the outside of the rotating rod 5, and a spring 13 also sleeved on the outside of the rotating rod 5 is provided between the top of the support ring 14 and the bottom of the vertical sleeve 7. During the vibration of the dispersion seat 6 of this structure, a force can be generated on the spring 13 with the cooperation of the support ring 14, which is beneficial to improve the stability of the dispersion seat 6 during vibration. A number of inclined rods 8 are evenly arranged around the outer wall of the vertical sleeve 7 and the inner wall of the dispersion seat 6.The two ends of the inclined rod 8 are welded and fixed to the outer wall of the vertical sleeve 7 and the inner wall of the dispersion seat 6, and the lower end of the inclined rod 8 is located at the connection with the dispersion seat 6, and a plurality of strip-shaped openings 18 are evenly arranged around the bottom wall of the dispersion seat 6. The dispersion seat 6 of this structure can disperse the granular raw materials added to the inside of the drying barrel 1 through a plurality of inclined rods 8 when rotating, and the granular raw materials entering the dispersion seat 6 will be evenly discharged from the plurality of strip-shaped openings 18. The front and rear ends of the horizontal axis 10 are symmetrically welded with baffle rods 19, and the baffle rods 19 and the horizontal axis 10 are vertically distributed. When the horizontal axis 10 of this structure rotates, the baffle rods 19 will also be driven to rotate, which allows the horizontal axis 10 and the baffle rods 19 to cooperate with each other to break up the granular raw materials that fall between the two dispersion seats 6, so that the granular raw materials can be dispersed in the drying barrel 1. The dispersion effect inside the barrel 1 is better, and the drying rate can be faster. The bottom of the conical seat 15 is provided with an overflow port. The conical seat 15 is a hollow structure as a whole, and a plurality of connecting rods 16 are arranged around the overflow port at the bottom of the conical seat 15. The two ends of the connecting rod 16 are respectively welded and fixed to the inner wall of the upper end of the overflow port of the conical seat 15 and the outer wall of the rotating rod 5, and three spacer rings 17 are evenly arranged on the inner wall of the conical seat 15. The spacer rings 17 are welded and fixed on the inner wall of the conical seat 15 and are horizontally distributed. When the granular raw materials fall into the interior of the conical seat 15, this structure gradually falls to the overflow port through contact with the three spacer rings 17. This enables the wind force delivered to the interior of the drying barrel 1 by the blower 2 to be more effective in blowing and drying the granular raw materials moving inside the conical seat 15, further improving the drying effect of the granular raw materials.
[0019] Working principle: When using the drying material energy-saving device of the injection molding machine, first start the control box between the ventilation pipe 3 and the blower 2. When the blower 2 conveys the wind from the ventilation pipe 3 to the inside of the drying material barrel 1, the drying material barrel 1 can add the injection molding granular raw materials in real time through the top feed port, and at the same time start the motor 4. When the motor 4 is driven, it will drive the rotating rod 5 to rotate. When the rotating rod 5 rotates, it can synchronously drive the two dispersion seats 6 and the conical seat 15 to rotate. When the dispersion seat 6 rotates, it will also drive a number of inclined rods 8 to rotate. At this time, when the granular raw materials fall into the inside of the dispersion seat 6, they will first contact with a number of inclined rods 8 for dispersion, and then enter the inside of the dispersion seat 6 and evenly fall from a number of strip-shaped openings 18. When the raw materials fall into the space between the two dispersion seats 6, the rotating rod 5 will also drive the horizontal axis 10 to rotate through the movable sleeve 11 when it rotates. When the shaft 10 rotates, it can cooperate with the baffle rod 19 to break up the granular raw materials, and then the granular raw materials will fall into the dispersion seat 6 below for redispersion. When the granular raw materials are dispersed inside the two dispersion seats 6, the small vibrator 12 can be started at the same time. When the small vibrator 12 is driven, it will directly act on the movable sleeve 11 to move outside the middle of the rotating rod 5. When the movable sleeve 11 moves, it will synchronously generate linkage with the two dispersion seats 6 through the horizontal axis 10 and the vertical axis 9. During the vibration of the dispersion seat 6, it can generate a force on the spring 13 with the cooperation of the support ring 14. At this time, the granular raw materials inside the dispersion seat 6 will move more evenly due to the vibration force, until the granular raw materials fall into the interior of the conical seat 15 and are dispersed by contact with the three spacer rings 17, and then fall into the overflow port at the bottom of the conical seat 15 and discharge from the gap between the connecting rods 16, thereby completing a series of tasks.
