Description

Technical Field

[0001] The utility model belongs to the technical field of granulator discharging mechanisms, in particular to a granulator discharging mechanism. Background Art

[0002] Polylactic acid foamed particles are a kind of granular material. The molding process generally includes stirring and mixing the materials, and extruding the materials into granular-sized particles through a granulator. After the granulator discharges the particles, the particles need to be collected and packaged.

[0003] When the polylactic acid foamed particles are discharged and packaged in containers or packaging bags, it is difficult to flexibly control the material discharge amount from the discharge port. Once the container is about to be full, the continuously discharged polylactic acid foamed particles may cause the container or packaging paper to overflow, causing material splashing. At the same time, the polylactic acid foamed particles may also cause material accumulation when discharged from the discharge port, causing blockage at the upper end opening of the discharge port. Therefore, the discharge amount of the polylactic acid foamed particles from the discharge port cannot be effectively controlled.

[0004] For this reason, a granulator discharging mechanism is proposed. Utility Model Content

[0005] The purpose of the utility model is to effectively control the discharge amount of polylactic acid foamed particles on the basis of preventing the discharge pipe from being blocked. The present application provides a granulator discharge mechanism.

A discharge pipe 52 is installed on the lower surface of the partition 51, and a solenoid valve 53 is provided on the outer surface of the lower end of the discharge pipe 52. The upper surface of the partition 51 is inclined from all sides toward the upper end opening of the discharge pipe 52; specifically, the motor 41 is started to make the rotating shaft 42 drive the cutting blade 43 to cut the polylactic acid foam material. After the polylactic acid foam material is cut into particles, the solenoid valve 53 can be opened to allow the polylactic acid foam particles to fall from the discharge pipe 52 to the inner bottom surface of the granulator case 1.

[0023] Reference Figure 1-Figure 3 The internal cavity at the bottom end of the granulator housing 1 is connected to a discharge pipe 12, and the inner bottom surface of the granulator housing 1 is inclined from all sides toward the upper end opening of the discharge pipe 12. Specifically, the polylactic acid foamed particles falling onto the inner bottom surface of the granulator housing 1 will flow downward along the discharge pipe 12. At this time, the staff can catch the polylactic acid foamed particles with a container or a packaging bag just below the discharge pipe 12.

[0024] Reference Figure 1-Figure 3 A discharging mechanism 6 is installed on the lower surface of the granulator housing 1 near the discharging pipe 12. The discharging mechanism 6 includes two electric cylinders 3 61. The electric cylinder 3 61 is fixedly connected to the lower surface of the granulator housing 1. A piston rod 3 62 is installed on the output end of the lower surface of the electric cylinder 3 61. The end of the piston rod 3 62 away from the electric cylinder 3 61 is fixedly connected to a connecting rod 63.

The sum of the heights of the plug 64 and the cone 65 is greater than the length of the discharging pipe 12, and the outer diameter of the plug 64 is matched with the inner diameter of the discharging pipe 12. Specifically, the electric cylinder 3 61 is started to make the piston rod 3 62 drive the connecting rod 63 and the plug 64 moves upward or downward, the downward moving plug 64 will drive the cone 65 to move outside the discharge pipe 12, at which time the gap between the inner wall of the bottom end of the discharge pipe 12 and the cone 65 will gradually increase, so as to speed up the discharge of the polylactic acid foamed particles; the upward moving plug 64 will drive the cone 65 to move inside the discharge pipe 12, at which time the gap between the inner wall of the bottom end of the discharge pipe 12 and the cone 65 will gradually decrease, thereby effectively controlling the amount of discharged polylactic acid foamed particles, and at the same time, the upward moving cone 65 and plug 64 can also clear the blocked discharge pipe 12; through the cooperation of the above structures, the discharge amount of the polylactic acid foamed particles can be effectively controlled on the basis of preventing the discharge pipe 12 from being blocked.

[0025] The implementation principle of the discharging mechanism of a granulator in the present application is as follows:

[0026] When using the device, first connect the external power supply, then start the hydraulic cylinder 22 to make the lifting column 23 drive the top cover 3 to move upward so as to expose the upper end opening of the top cover 3, and then put the polylactic acid foam material into the interior of the granulator case 1. These materials will fall to the upper surface of the partition 51. At this time, the motor 41 can be started to make the rotating shaft 42 drive the cutting blade 43 to cut the polylactic acid foam material. After the polylactic acid foam material is cut into particles, the solenoid valve 53 can be opened to allow the polylactic acid foam particles to fall from the discharge pipe 52 to the inner bottom surface of the granulator case 1.

[0027] At the same time, the electric cylinder three 61 can be started to make the piston rod three 62 drive the connecting rod 63 and the plug 64 to move upward or downward. The plug 64 moving downward will drive the cone 65 to move outside the discharge pipe 12. At this time, the gap between the inner wall of the bottom end of the discharge pipe 12 and the cone 65 will gradually increase, so as to speed up the discharge of the polylactic acid foamed particles; the plug 64 moving upward will drive the cone 65 to move inside the discharge pipe 12. At this time, the gap between the inner wall of the bottom end of the discharge pipe 12 and the cone 65 will gradually decrease, thereby effectively controlling the amount of discharged polylactic acid foamed particles. At the same time, the cone 65 and the plug 64 moving upward can also clear the blocked discharge pipe 12. Through the cooperation of the above structures, the discharge amount of the polylactic acid foamed particles can be effectively controlled on the basis of preventing the discharge pipe 12 from being blocked.
