Description

Technical Field

[0001] The utility model relates to the technical field of extruder equipment, in particular to a feeding device for an extruder with a stirring function. Background Art

[0002] The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and then form it through the die. When the extruder is in use, the plastic particles need to be evenly transported to the inside of the extruder through the feeding device to avoid the plastic particles directly pouring into the extruder and causing blockage of the extruder.

[0003] For example, the utility model: "A feeding device for a single-screw extruder with a stirring function", with the announcement number: "CN213860611U", drives the rotating gear and the support plate to form a rotating structure through the rotation of the half gear, so that the hole and the first through hole overlap and separate, thereby realizing the gap feeding of plastic particles, avoiding the blockage of the single-screw extruder, and improving the service life of the single-screw extruder. However, during the implementation of the patent, the installation position of the stirring mechanism is fixed, and the plastic particles at different positions cannot be stirred, and the stirring effect is poor. In addition, the plastic particles can directly pass through the rotating gear and get stuck between the support plate and the rotating gear, which will affect the use of the rotating gear. Therefore, a new type of feeding device for an extruder with a stirring function is urgently needed to solve the above problems. Utility Model Content

The first rotating shaft 3 passes through the material discharge bin 1, and a turntable 2 is installed at the end of the first rotating shaft 3 away from the second motor 15. A material discharge disc 4 is installed on the outer side of the first rotating shaft 3, and material discharge troughs 5 are evenly arranged on the outer side of the material discharge disc 4. A control panel 16 is installed at the bottom of the mounting plate 14 away from the material discharge bin 1, and the output end of the control panel 16 is electrically connected to the input end of the first motor 12 and the second motor 15 through wires.

[0022] In this implementation:

[0023] Furthermore, a material guide pipe 6 is installed at the bottom of the mixing bin 7 , and the material guide pipe 6 passes through the lower bin 1 and extends to the inside of the lower bin 1 , and the plastic particles inside the mixing bin 7 can be discharged into the lower trough 5 through the material guide pipe 6 .

[0024] Furthermore, a second rotating shaft 11 is installed at the output end of the first motor 12, and a stirring rod 10 is evenly installed on the outer side of the second rotating shaft 11. The first motor 12 drives the stirring rod 10 to rotate through the second rotating shaft 11, so that the plastic particles inside the stirring chamber 7 can be evenly stirred.

[0025] Furthermore, a fixing rod 20 is installed at the edge position of the turntable 2 away from the first rotating shaft 3, and a bearing 19 is installed on the outer side of the fixing rod 20. A connecting rod 8 is hinged on the outer side of the bearing 19, and the end of the connecting rod 8 away from the bearing 19 is hinged to the lifting plate 9. When in use, the turntable 2 drives the fixing rod 20 to rotate, so that the connecting rod 8 can push and pull the lifting plate 9 to move back and forth, and the stirring rod 10 can be moved back and forth to different positions inside the stirring chamber 7 for stirring. The device has a high degree of automation and is relatively convenient to use.

[0026] Furthermore, twelve groups of feed chutes 5 are provided, and the angle between two adjacent groups of feed chutes 5 is thirty degrees.

[0027] Furthermore, mounting through holes are evenly arranged inside the mounting plate 14, so as to facilitate the mounting of the mounting plate 14 at a designated position of the extruder.

[0028] Furthermore, a discharge pipe 18 is installed at the middle position of the bottom of the discharge bin 1, and the plastic particles inside the discharge trough 5 are discharged into the discharge pipe 18 by gravity, and can be discharged into the extruder through the discharge pipe 18.

[0029] Working principle:

[0030] When in use, the device is connected to a power source and an appropriate amount of plastic particles are added into the mixing chamber 7;

[0031] The staff can start the first motor 12 and the second motor 15 through the control panel 16, and the first motor 12 drives the stirring rod 10 to rotate through the second rotating shaft 11, so that the plastic particles inside the stirring chamber 7 can be stirred evenly;

[0032] The second motor 15 drives the feeding disc 4 to rotate at a constant speed through the first rotating shaft 3. When the feeding trough 5 on the feeding disc 4 rotates to a position facing the guide pipe 6, the plastic particles in the mixing bin 7 can be fed into the feeding trough 5 through the guide pipe 6.

[0033] When the feeding chute 5 rotates to a position facing the feeding pipe 18, the plastic particles in the feeding chute 5 are fed into the feeding pipe 18 by gravity, and can be fed into the extruder through the feeding pipe 18;

[0034] During use, the first rotating shaft 3 drives the rotating disk 2 to rotate together, and the rotating disk 2 drives the fixing rod 20 to rotate. Since the fixing rod 20 is installed on the inner ring of the bearing 19, and the connecting rod 8 is installed on the outer ring of the bearing 19, the connecting rod 8 can rotate independently outside the fixing rod 20 through the bearing 19, so that the connecting rod 8 can always face upward;

[0035] When the fixed rod 20 rotates upward, the fixed rod 20 drives the connecting rod 8 to move through the bearing 19, so that the connecting rod 8 is subjected to force and pushes the lifting plate 9 to move upward, thereby driving the stirring rod 10 to move upward;

[0036] When the fixed rod 20 rotates downward, the fixed rod 20 drives the connecting rod 8 to move through the bearing 19, so that the connecting rod 8 is stressed and pulls the lifting plate 9 to move downward, thereby driving the stirring rod 10 to move downward;

[0037] Since the second motor 15 drives the turntable 2 to rotate at a constant speed through the first rotating shaft 3, the connecting rod 8 can push and pull the lifting plate 9 to move back and forth, and the stirring rod 10 can be moved back and forth to different positions inside the stirring chamber 7 for stirring. The device has a high degree of automation and is more convenient to use.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
