Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of extruder equipment, in particular to an anti-blocking device for an extruder feeding port. Background Art
[0002] The 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. During the use of the extruder, the material enters the extruder through the feeding port. During the feeding process, the material can easily block the feeding port, causing the extruder to be underfed. Therefore, anti-blocking equipment needs to be used in conjunction.
[0003] For example, the utility model: "An automatic feeding and anti-blocking device for a screw extruder", with the announcement number: "CN213891155U", applies a vertical downward impact force to the limiting plate, causing the limiting plate to vibrate, driving the insertion rod to vibrate, and the insertion rod driving the recessed portion to vibrate, thereby making the discharge port less prone to blockage and improving the discharge efficiency of the extruder discharge port. However, during the implementation of this patent, if the discharge port has been blocked by material, it is difficult to quickly clear the discharge port by only shaking the insertion rod, which greatly reduces the anti-blocking effect of the device. Therefore, there is an urgent need for an extruder feeding port anti-blocking device to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide an anti-blocking device for the feeding port of an extruder to solve the problems raised in the above background technology.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figure 1-3 , the utility model provides an embodiment: an extruder feeding port anti-blocking device, including a material guide bin 3 and a lifting plate 8, a sliding assembly 6 is installed on the top of one end of the material guide bin 3, and a lifting plate 8 is slidably installed on the inner side of the sliding assembly 6, and a first motor 7 is installed at the bottom of the lifting plate 8, where the first motor 7 model can be Y90S-2, a feeding pipe 1 is installed at the middle position of the bottom of the material guide bin 3, and a second motor 11 is installed at the end of the top of the material guide bin 3 away from the feeding pipe 5, where the second motor 11 model can be Y90S-2, a first rotating shaft 10 is installed at the output end of the second motor 11, and an elliptical protrusion 9 is installed at the end of the first rotating shaft 10 away from the second motor 11, and a control panel 16 is installed at the bottom of the material guide bin 3 near the second motor 11, and the output end of the control panel 16 is electrically connected to the input end of the first motor 7 and the second motor 11 through a wire.
[0022] In this implementation:
[0023] Furthermore, a second rotating shaft 15 is installed at the output end of the first motor 7, and a stirring rod 4 is evenly installed on the outside of the second rotating shaft 15. The first motor 7 drives the stirring rod 4 to rotate at a uniform speed through the second rotating shaft 15. The stirring rod 4 stirs the material, and the material inside the material guide bin 3 can be stirred, which can not only disperse the materials that are stuck together, but also make the materials evenly mixed.
[0024] Furthermore, an anti-blocking rod 2 is installed at the bottom of the second rotating shaft 15. When the anti-blocking rod 2 is inserted into the feeding pipe 1, the material can be directly pushed from the inside of the feeding pipe 1 to the inside of the extruder feeding port through the anti-blocking rod 2, and the material can be discharged into the inside of the extruder.
[0025] Furthermore, a group of protrusions 14 are symmetrically provided on the outer side of the elliptical protrusion 9. When the protrusions 14 on the elliptical protrusion 9 rotate to contact the balls 18, the elliptical protrusion 9 squeezes the balls 18, causing the lifting plate 8 to be subjected to force and move downward.
[0026] Furthermore, a ball groove 17 is provided on the top of the lifting plate 8, and a ball 18 is installed inside the ball groove 17. When the elliptical protrusion 9 rotates, the ball 18 can rotate inside the ball groove 17 under the force, and the ball 18 will not affect the rotation of the elliptical protrusion 9.
[0027] Furthermore, a fixed plate 13 is installed on the top of the end of the guide bin 3 away from the sliding assembly 6, and a return spring 12 is installed on the top of the fixed plate 13. The end of the return spring 12 away from the fixed plate 13 is connected to the lifting plate 8. When the protrusion 14 on the elliptical protrusion 9 rotates to a position away from the ball 18, the elliptical protrusion 9 no longer squeezes the ball 18. At this time, the elastic action of the return spring 12 pushes the lifting plate 8 to move upward and reset, and makes the ball 18 fit tightly with the outer side of the elliptical protrusion 9, so that the anti-blocking rod 2 can be taken out from the inside of the feeding pipe 1.
[0028] Furthermore, a feed pipe 5 is installed on the top of the guide bin 3 away from the second motor 11 , and a feed hopper is installed on the top of the feed pipe 5 to facilitate adding materials into the guide bin 3 .
[0029] Working principle:
[0030] When in use, install the guide bin 3 above the extruder so that the feeding pipe 1 is connected to the feeding port of the extruder, and then connect the device to the power supply;
[0031] The staff can start the first motor 7 through the control panel 16, so that the first motor 7 drives the stirring rod 4 to rotate at a constant speed through the second rotating shaft 15. The stirring rod 4 stirs the material, and the material inside the guide bin 3 can be stirred, which can not only break up the materials that are stuck together, but also make the materials evenly mixed.
[0032] At the same time, the staff can start the second motor 11 through the control panel 16, so that the second motor 11 drives the elliptical protrusion 9 to rotate at a constant speed through the first rotating shaft 10;
[0033] When the raised portion 14 on the elliptical protrusion 9 rotates to contact the ball 18, the elliptical protrusion 9 squeezes the ball 18, so that the lifting plate 8 is subjected to force and moves downward, the lifting plate 8 squeezes the return spring 12, and the lifting plate 8 drives the first motor 7 to move downward together, so that the anti-blocking rod 2 can be inserted into the feeding pipe 1. The material can be directly pushed from the inside of the feeding pipe 1 to the inside of the extruder feeding port through the anti-blocking rod 2, and the material is discharged into the extruder;
[0034] When the raised portion 14 on the elliptical protrusion 9 rotates to a position away from the ball 18, the elliptical protrusion 9 no longer squeezes the ball 18. At this time, the elastic action of the return spring 12 causes it to push the lifting plate 8 to move upward and return to its original position, so that the ball 18 fits tightly against the outer side of the elliptical protrusion 9, and the anti-blocking rod 2 can be removed from the inside of the feeding pipe 1.
[0035] Since the second motor 11 drives the elliptical protrusion 9 to rotate at a constant speed through the first rotating shaft 10, the second motor 11 on the elliptical protrusion 9 can reciprocatingly squeeze the ball 18, thereby pushing the lifting plate 8 to move back and forth, and the stirring rod 4 can be reciprocated to different positions inside the material guide bin 3 for stirring, and the anti-blocking rod 2 can be reciprocated to the inside of the feeding pipe 1, and the inside of the feeding pipe 1 can be reciprocated for dredging. The device has a high degree of automation and is relatively convenient to use.
[0036] It will be apparent 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 characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
