Description

Technical Field

[0001] The present invention relates to the technical field of front-end frame production, and particularly to a raw material feeding device for front-end frame production. Background Art

[0002] As a high-performance engineering plastic, PPS plays a crucial role in the manufacture of automotive front-end frames. This front-end frame made of engineering plastics is produced by special equipment. To ensure the efficient operation of the production equipment, a raw material feeding device is usually equipped to convey plastic particles into the equipment.

[0003] The currently existing raw material feeding devices used in front-end frame production have certain limitations in actual application. The raw material feeding devices are generally designed and finalized according to the specific requirements of single-specification end-frame production equipment, which results in that they can only be used in conjunction with end-frame production equipment of such specifications and cannot meet diverse production needs. In addition, in the conveying process of plastic particles, a normal-temperature conveying method is usually adopted. After the relatively low-temperature plastic particles are conveyed into the equipment, it takes a long time to completely melt. This situation not only prolongs the production cycle but also makes it difficult to effectively improve the overall production efficiency. Summary of the Invention

[0004] The present disclosure relates to a raw material feeding device for front-end frame production, which solves the problem that the currently existing raw material feeding devices used in front-end frame production have certain limitations in actual application. The raw material feeding devices are generally designed and finalized according to the specific requirements of single-specification end-frame production equipment, which results in that they can only be used in conjunction with end-frame production equipment of such specifications and cannot meet diverse production needs.

[0006] Further, the feed inlet at the bottom of the screw conveyor is rotatably connected to the storage hopper, and the discharge outlet at the top of the screw conveyor is rotatably connected to the leakage nozzle.

[0007] Further, the intake end and the exhaust end of the heating sleeve are connected to the high-temperature steam pipeline. A spiral baffle is arranged inside the heating sleeve, and the spiral channel formed inside the heating sleeve surrounds the outside of the screw conveyor.

[0008] Further, the telescopic rod is composed of a hollow bottom rod and a solid top rod. The bottom of the hollow bottom rod is rotatably connected to the support chassis, the top of the solid top rod is rotatably connected to the heating sleeve, and the bottom of the solid top rod is slidably inserted into the hollow bottom rod.

[0009] Further, the main housing is welded to the top of the hollow bottom rod. The inner wall of the main housing is inclined, the outer wall of the movable sliding sleeve is inclined, the solid top rod slidably penetrates through the main housing and the movable sliding sleeve, a spring is installed inside the main housing, the spring surrounds the outside of the solid top rod, the upper end of the spring contacts the main housing, and the lower end of the spring contacts the movable sliding sleeve.

[0010] Further, clamping holes are arranged in a surrounding manner at the inclined outer wall position of the movable sliding sleeve, metal beads are located in the clamping holes, one end of the metal bead contacts the inclined inner wall of the main housing, and the opposite end of the metal bead contacts the solid top rod.

[0011] Further, a movable hole is arranged outside the main housing, the unlocking ring is slidably connected to the main housing, a connecting column is arranged inside the unlocking ring, the connecting column is slidably connected in the movable hole, a connecting groove is arranged outside the movable sliding sleeve, and the end of the connecting column is located in the connecting groove.

[0012] Further, a small extraction and discharge opening is arranged at the bottom of the hollow bottom rod, the small extraction and discharge opening is communicated with the inside of the hollow bottom rod, the small extraction and discharge opening is communicated with the water tank through a pipeline, and two rubber sealing rings are sleeved at the bottom of the solid top rod, and the rubber sealing rings are in sliding contact with the inner wall of the hollow bottom rod.

[0013] The present invention provides a raw material feeding device for the production of a front-end frame, and has the following beneficial effects: When the present invention is in use, the screw conveyor can be flexibly adjusted according to the differences in the specifications of the front-end frame production equipment, and the height of the material leakage nozzle can be accurately changed so that it is exactly at the top of the feeding port of the production equipment, thereby better adapting to the feeding requirements of different specifications of front-end frame production equipment and showing strong general performance; during the process of the plastic particles being conveyed upward by the screw conveyor, high-temperature steam will enter the inside of the heating sleeve, and the spiral baffle plays a role in changing the flow direction of the high-temperature steam, so that the high-temperature steam flows around the screw conveyor in a spiral shape. In this way, the screw conveyor can fully absorb the heat contained in the high-temperature steam, and then realize the preheating effect on the plastic particles, which can effectively shorten the subsequent melting time of the plastic particles, thereby significantly improving the production efficiency.

[0014] In addition, when the telescopic rod extends upward, the inclination angle of the screw conveyor increases, and the height of the material leakage nozzle rises accordingly. When the telescopic rod contracts downward, the inclination angle of the screw conveyor decreases, and the height of the material leakage nozzle drops accordingly. After the solid ejector rod stops adjusting, the moving sliding sleeve will move downward and reset under the action of the spring. The distance between the inclined outer wall of the moving sliding sleeve and the inclined inner wall of the main housing gradually decreases. The metal beads move inward under the action of the thrust, making the metal beads in close contact with the solid ejector rod, achieving the effect of unidirectional locking and fixing of the solid ejector rod, enabling the solid ejector rod to move freely upward, and effectively preventing it from moving downward due to gravity, ensuring the stability of the working state of the screw conveyor. When it is necessary to lower the height of the material leakage nozzle, only need to move the unlocking ring upward. The unlocking ring drives the moving sliding sleeve to move upward together. The spring contracts due to the force. The distance between the inclined outer wall of the moving sliding sleeve and the inclined inner wall of the main housing gradually increases. The metal beads can move outward. The solid ejector rod moves downward under the action of the gravity applied by the screw conveyor, successfully completing the operation of lowering the height of the material leakage nozzle. The whole process is simple and easy to operate.

[0015] In addition, when the telescopic rod extends, the water in the water tank is pumped through the pipeline and conveyed to the inside of the hollow bottom rod. During the contraction process of the telescopic rod, the water in the hollow bottom rod is discharged back into the water tank through the pipeline. Since the cross-sectional area of the small pumping and discharging orifice is small, the pumping and discharging speed of the water slows down accordingly, and then the extending and contracting actions of the telescopic rod also become slow correspondingly, effectively avoiding potential safety hazards that may be caused by the too-fast downward adjustment of the telescopic rod.

The spiral baffle 501 plays a role in changing the flow direction of the high-temperature steam, causing the high-temperature steam to flow around the screw conveyor 3 in a spiral shape. In this way, the screw conveyor 3 can fully absorb the heat contained in the high-temperature steam, thereby realizing the preheating effect on the plastic particles, effectively shortening the subsequent melting time of the plastic particles, and significantly improving the production efficiency.

[0025] In the embodiment of the present disclosure, the main housing 8 is welded to the top of the hollow bottom rod 71. The inner wall of the main housing 8 is inclined, and the outer wall of the movable sliding sleeve 9 is inclined. The solid top rod 72 slides through the main housing 8 and the movable sliding sleeve 9. A spring 11 is installed inside the main housing 8. The spring 11 surrounds the outside of the solid top rod 72. The upper end of the spring 11 contacts the main housing 8, and the lower end of the spring 11 contacts the movable sliding sleeve 9.

[0026] In the embodiment of the present disclosure, clamping holes 901 are arranged in a surrounding manner at the inclined outer wall position of the movable sliding sleeve 9.

The distance between the inclined outer wall of the movable sliding sleeve 9 and the inclined inner wall of the main housing 8 gradually decreases. The metal bead 10 moves inward under the action of the thrust force, so that the metal bead 10 is in close contact with the solid top rod 72, achieving the effect of one-way locking and fixing of the solid top rod 72, enabling the solid top rod 72 to move upward freely, and effectively preventing it from moving downward due to gravity, ensuring the working state stability of the screw conveyor 3.

[0027] In the embodiment of the present disclosure, an activity hole 801 is arranged outside the main housing 8. The unlocking ring 12 is slidably connected to the main housing 8.

The end of the connecting column 1201 is located in the connecting groove 902; When it is necessary to reduce the height of the material leakage nozzle 4, only need to move the unlocking ring 12 upward. The unlocking ring 12 drives the movable sliding sleeve 9 to move upward together. The spring 11 contracts due to the force. The distance between the inclined outer wall of the movable sliding sleeve 9 and the inclined inner wall of the main housing 8 gradually increases. The metal bead 10 can move outward. The solid top rod 72 moves downward under the action of the gravity applied by the screw conveyor 3, and the operation of lowering the height of the material leakage nozzle 4 is successfully completed. The whole process is simple and easy to operate.

[0028] In the second embodiment, on the basis of the first embodiment, a small pumping port 7101 is arranged at the bottom of the hollow bottom rod 71. The small pumping port 7101 is communicated with the inside of the hollow bottom rod 71. The small pumping port 7101 is communicated with a water tank through a pipeline. Two rubber sealing rings 7201 are sleeved at the bottom of the solid top rod 72.

During the contraction process of the telescopic rod 7, the water in the hollow bottom rod 71 is drained back into the water tank through the pipeline. Since the cross-sectional area of the pumping and draining small opening 7101 is small, the pumping and draining speed of the water slows down, and thus the extension and contraction actions of the telescopic rod 7 also become correspondingly slow, effectively avoiding potential safety hazards that may be caused by the telescopic rod 7 being lowered too quickly.

[0029] The working principle of this embodiment: First, the supporting chassis 1 is supported by the universal wheels 101 to move the raw material feeding device. When it is moved to the required position, the supporting leg 6 is rotated so that the bottom of the supporting leg 6 contacts the ground, and the supporting chassis 1 is supported by the supporting leg 6 to avoid the occurrence of displacement of the supporting chassis 1 and ensure the stability of the state of the raw material feeding device; Next, according to the differences in the specifications of the front-end frame production equipment, the screw conveyor 3 is flexibly adjusted to accurately change the height of the material leakage nozzle 4 so that it is exactly at the top of the feeding port of the production equipment, thus better adapting to the feeding requirements of different specifications of the front-end frame production equipment; After the solid top rod 72 stops adjusting, the moving sliding sleeve 9 will move downward and reset under the action of the spring 11. The distance between the inclined outer wall of the moving sliding sleeve 9 and the inclined inner wall of the main housing 8 gradually decreases, and the metal beads 10 move inward under the action of the thrust force, making the metal beads 10 in close contact with the solid top rod 72, achieving the effect of one-way locking and fixing of the solid top rod 72, enabling the solid top rod 72 to move freely upward and effectively preventing it from moving downward due to gravity, ensuring the stability of the working state of the screw conveyor 3; When it is necessary to lower the height of the material leakage nozzle 4 later, only need to move the unlocking ring 12 upward, and the unlocking ring 12 drives the moving sliding sleeve 9 to move upward together. The spring 11 contracts due to the force, and the distance between the inclined outer wall of the moving sliding sleeve 9 and the inclined inner wall of the main housing 8 gradually increases, and the metal beads 10 can move outward. The solid top rod 72 moves downward under the action of the gravity exerted by the screw conveyor 3, successfully completing the operation of lowering the height of the material leakage nozzle 4; When the telescopic rod 7 extends, the water in the water tank is pumped through the pipeline and delivered to the inside of the hollow bottom rod 71. During the contraction process of the telescopic rod 7, the water in the hollow bottom rod 71 is drained back into the water tank through the pipeline. Since the cross-sectional area of the pumping and draining small opening 7101 is small, the pumping and draining speed of the water slows down, and thus the extension and contraction actions of the telescopic rod 7 also become correspondingly slow, effectively avoiding potential safety hazards that may be caused by the telescopic rod 7 being lowered too quickly.
