[0010] Furthermore, the upper end of the material guide trough is vertical, the lower end of the material guide trough is inclined, and the distance between the upper end axis of the material guide trough and the end tube axis is greater than the distance between the lower end of the material guide trough and the end tube axis.

[0011] Furthermore, the upper end of the pushing column is a tapered end, the outer diameter of the lower end of the pushing column is equal to the inner diameter of the ring column, and the plurality of penetration grooves are evenly distributed in a circular array around the axis of the ring column.

[0017] III) Beneficial effects:

[0018] Compared with the prior art, the syringe crushing device for medical waste recycling has the following beneficial effects:

[0019] 1. The present invention is provided with components such as a feeding trough, a guide trough, a pushing column, a vertical cutting wheel and a sickle-shaped cross-cutting knife. When the power telescopic rod pushes the pushing column to move upward, the syringe above the pushing column gradually moves upward. When the syringe moves to above the ring column, the syringe in a vertical direction will tilt toward one side of the guide trough and fall into the guide trough. After the syringe falling into the guide trough falls into the feeding trough, the vertical cutting wheel cuts the cylindrical syringe in half, and the sickle-shaped cross-cutting knife cuts and crushes the syringe that has been cut in half for many times while rotating, ensuring that the broken syringe will not have ring-shaped fragments, which is convenient for later processing of the fragments.

[0020] 2. The present invention provides a pressure rod, a center disk and a thrust telescopic rod. The thrust telescopic rod has a tendency to push the pressure rod to contact the inner wall of the material guide trough. When the center disk moves downward following the material pushing column, the pressure rod is driven to move downward in the material guide trough by the thrust telescopic rod, and the syringe in the material guide trough is assisted in being pushed into the material penetration trough. When the pressure rod moves to the inclined end of the material guide trough, the pressure rod can move downward along the inclined trajectory of the material guide trough by compressing the thrust telescopic rod, and the syringe is pushed into the material penetration trough, and the syringe is assisted in being pushed downward in the material penetration trough, so that the vertical cutting wheel can stably cut the syringe.

[0021] 3. The present invention provides a through-groove cylinder and an elastic damping sheet. The elastic damping sheet generates support resistance to the syringe on one side bent in the guide groove, so that the syringe will move downward in the guide groove only when it is pushed from above, thereby increasing the crushing time of the sickle-shaped cross-cutting knife on the syringe, thereby increasing the degree of crushing of the syringe.

[0022] Fourth, the present invention provides an air cavity, an air outlet groove and an air pump, and the air pump fills air into the air cavity. When the pushing column moves upward to push the syringe to the top of the ring column, part of the syringe moves to between the end tube and the pushing column. After the air outlet groove moves to the top of the ring column, the airflow ejected from the air outlet groove assists in pushing the syringe between the end tube and the pushing column into the guide groove, making it easier for the syringe to enter the threading groove.

[0035] A vertical cutting wheel 6 is arranged inside each threading trough 5, and the ring column 4 is rotatably sleeved on the outer surface of the vertical cutting wheel 6. When the syringe moves downward in the threading trough 5 and passes through the vertical cutting wheel 6, it is cut into two halves by the vertical cutting wheel 6, so as to ensure that there are no annular fragments of the syringe after the later crushing, and that the fragments do not have double layers. The vertical cutting wheel 6 is located at the axis of the outer ring side of the ring column 4 and is rotatably connected with a longitudinal frame 7. The upper end of the longitudinal frame 7 is fixed to the fixed outer frame 2, and a transmission structure 8 is installed at the end of the longitudinal frame 7 away from the ring column 4. The vertical cutting wheel 6 and the transmission structure 8 connected to the same longitudinal frame 7 are driven by a conveyor belt 14.

[0036] The outer surface of the ring column 4 is rotatably sleeved with a rotating frame 9, and the upper end of the rotating frame 9 is coaxially fixed with an inner bevel gear ring 10, and the upper end outer ring surface of the inner bevel gear ring 10 is meshed with a spur gear 23, and the surface of the fixed outer frame 2 is installed with a motor 24, and the spur gear 23 is coaxially fixed with the output end of the motor 24, and the meshing part of the upper end of the inner bevel gear ring 10 and the spur gear 23 is a spur gear shape, and the motor 24 is meshed with the upper end of the inner bevel gear ring 10 through the spur gear 23 to drive the inner bevel gear ring 10 to rotate, and the transmission structure 8 is meshed with the inner ring of the inner bevel gear ring 10 The transmission structure 8 includes a vertical bevel gear set 81 and a longitudinal bevel gear 82. The lower end of the vertical bevel gear set 81 is meshed with the longitudinal bevel gear 82. The vertical bevel gear set 81 and the longitudinal bevel gear 82 are both rotatably connected to the adjacent longitudinal frame 7. The upper and lower ends of the vertical bevel gear set 81 are both bevel gear-shaped. The upper end of the vertical bevel gear set 81 is meshed with the inner ring surface of the inner bevel gear ring 10. One end of the longitudinal bevel gear 82 is connected to the conveyor belt 14. The meshing position of the lower end of the inner bevel gear ring 10 and the vertical bevel gear set 81 is bevel gear-shaped.

[0037] A plurality of annular grooves 11 are provided inside the annular column 4, and a circular ring 12 is rotatably inserted inside each annular groove 11. The circular ring 12 is fixedly mounted on the lower end of the rotating frame 9, and a plurality of sickle-shaped cross-cutting knives 13 are fixed on the inner annular surface of the circular ring 12. The circular ring 12 is located below the vertical cutting wheel 6, and a material guide groove 16 is provided on the inner annular surface of the end tube 3 and above each material penetration groove 5. The upper end of the material guide groove 16 is vertical, and the lower end of the material guide groove 16 is inclined. The distance between the upper end axis of the material guide groove 16 and the axis of the end tube 3 is greater than the distance between the lower end of the material guide groove 16 and the axis of the end tube 3. The syringe entering the material guide groove 16 is tilted outward, which can effectively prevent the syringe that falls into the material guide groove 16 from escaping from the material guide groove 16 again.

[0038] A pushing column 15 is slidably inserted into the inner ring surface of the ring column 4, and a power telescopic rod 17 is fixed to the lower end of the pushing column 15. The lower end of the power telescopic rod 17 is fixed to the device base 1, and the upper end of the pushing column 15 is a tapered end. The outer diameter of the lower end of the pushing column 15 is equal to the inner diameter of the ring column 4. The syringe has a tendency to slide toward the connection between the pushing column 15 and the ring column 4, so that when the pushing column 15 pushes the syringe to move upward, it has a tendency to push the syringe to move above the ring column 4. The syringe to be cleaned is placed above the pushing column 15 in the ring column 4. Multiple threading grooves 5 are evenly distributed in a circular array around the axis of the ring column 4, and can push the upper syringe to move upward when the pushing column 15 moves upward.

[0039] An air cavity 151 is provided at the axis of the push column 15, and a plurality of air outlet grooves 152 are provided on the inner wall of the air cavity 151. The number of the air outlet grooves 152 is the same as the number of the threading grooves 5, and the plurality of air outlet grooves 152 respectively correspond to the positions of the plurality of threading grooves 5. An air pump 153 connected to the inside of the air cavity 151 is installed on the bottom surface of the push column 15. The air pump 153 has a tendency to fill the air cavity 151 with air. After the push column 15 pushes the syringe upward and the air outlet groove 152 moves to the top of the ring column 4, the airflow ejected from the air outlet groove 152 assists in pushing the syringe on one side into the guide groove 16. The inside of the threading groove 5 is the same as that of the push column 15. A slotted cylinder 21 is fixed to the shaft, and the slotted cylinder 21 is located below the annular groove 11. The inner annular surface of the slotted cylinder 21 is a plurality of vertical slot-like structures. An elastic damping sheet 22 is installed inside each vertical slot-like structure of the slotted cylinder 21. The middle portion of the elastic damping sheet 22 is bent toward one side of the axis of the material penetration groove 5. The portion of the elastic damping sheet 22 bent toward the axis of the material penetration groove 5 has a tendency to block the syringe above, thereby increasing the time for the sickle-shaped cross-cutting knife 13 to cut and crush the syringe, and increasing the degree of crushing. The syringe above will fall from between the elastic damping sheets 22 only after it is under pressure or crushed to a small enough size.

[0040] The end tube 3 is internally slidably plugged with a material pressing structure 18, and the material pressing structure 18 is coaxially fixed with a center column 19. The lower end of the center column 19 is coaxially installed with the material pushing column 15. The material pressing structure 18 includes a center disk 181 and a plurality of pressure rods 182. The number of the pressure rods 182 is equal to the number of the material guide grooves 16. The pressure rods 182 are slidably plugged into the inside of the adjacent material guide grooves 16. The end of the pressure rod 182 close to the center disk 181 is fixed with a thrust telescopic rod 183. The other end of the thrust telescopic rod 183 is fixed with the center disk 181. The outer annular surface of the core disk 181 is fixed, and the center disk 181 is coaxially fixed with the upper end of the center column 19. The thrust telescopic rod 183 has a tendency to push the pressure rod 182 to move into the material guide groove 16. When the pressure rod 182 moves downward, the pressure rod 182 gradually compresses the thrust telescopic rod 183 to move downward. When the pressure rod 182 moves downward, it can assist in pushing the syringe below into the material penetration groove 5, so that the syringe is subjected to sufficient pressure, and the vertical cutting wheel 6 and the sickle-shaped cross-cutting knife 13 can crush the syringe.

[0041] Working principle: put the syringe to be processed above the push column 15 on the inner ring side of the ring column 4, and the power telescopic rod 17 pushes the push column 15 to move upward, pushing the injection tube above to move upward. Since the upper end of the push column 15 is conical, the injection tube has a tendency to slide toward the connection between the push column 15 and the ring column 4. When the syringe moves to the top of the ring column 4, part of the syringe falls between the end tube 3 and the push column 15, and the air pump 153 fills the air cavity 151 with air. After the air outlet groove 152 moves to the top of the ring column 4, the airflow ejected from the air outlet groove 152 assists in pushing the syringe between the end tube 3 and the push column 15 into the guide groove 16, and then the push column 15 moves downward, bringing The dynamic pressure rod 182 moves downward, pushing the syringe in the guide groove 16 to gradually move into the inside of the guide groove 16. When the inner bevel gear ring 10 rotates, it drives the vertical bevel gear group 81 to rotate through the vertical bevel gear group 81. After the longitudinal bevel gear 82 meshes with the vertical bevel gear group 81 and rotates, the vertical cutting wheel 6 is rotated through the conveyor belt 14. At the same time, the rotating frame 9 drives the sickle-shaped cross-cutter 13 to rotate through the circular ring 12. After the syringe falling into the guide groove 16 falls into the feeding groove 5, the vertical cutting wheel 6 cuts the cylindrical syringe in half. The sickle-shaped cross-cutter 13 cuts and crushes the syringe that has been cut in half for multiple times while rotating to ensure that the broken syringe will not have ring-shaped fragments, which is convenient for later processing of the fragments.
