Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding warning technology, in particular to a feeding warning device for an extruder for preventing plastic rods from breaking. Background Art
[0002] Extruders are widely used in the production of plastics, rubber and other products. Plastic extruders are the main molding equipment for making thermoplastics or thermosetting plastics into plastic products of various shapes using plastic molding molds. They are divided into vertical, horizontal and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics to make them ejected and fill the mold cavity.
[0003] When the existing extruder is performing feeding operations, the raw materials enter the subsequent steps through the lower hopper, and the raw materials are easily blocked inside the lower hopper, resulting in cracks on the surface of the final extruded plastic rod or even direct breakage, affecting production quality and increasing the cost of raw material loss. Utility Model Content
[0004] The utility model discloses a feeding early warning device for an extruder for preventing plastic rod breakage, aiming to solve the technical problem that the lower hopper of the existing extruder is prone to blockage, resulting in breakage of the extruded plastic rod.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a feeding warning device for an extruder to prevent plastic rod breakage, comprising an extruder body, an anti-blocking module is arranged on the upper side of the extruder body, and the anti-blocking module comprises a plurality of telescopic springs and two rotating columns, one end of the plurality of telescopic springs is fixedly connected to an L-shaped fixing block, and the ends of the plurality of L-shaped fixing blocks away from the extruder body are fixedly connected to the same lower hopper, the upper side of the lower hopper is fixedly connected to a mounting plate, and one side of the mounting plate is provided with symmetrical through holes, and the insides of the through holes are fixedly connected to limiting columns , one end of the two limit columns away from the mounting plate is fixedly connected to one side of the extruder body; a driving motor is fixedly connected to one side of the mounting plate, and the driving end of the driving motor is connected to one end of one of the rotating columns through a coupling; circular holes are opened at opposite ends of the two rotating columns, and the inside of the two circular holes is fixedly connected with the same telescopic rod, and the outside of the telescopic rod and one of the rotating columns is fixedly connected with a fixing ring; stirring rods are fixed at equal distances on the outside of the two fixing rings, and the ends of the two upper and lower corresponding stirring rods away from the rotating columns are fixedly connected with the same cleaning soft plate.
[0006] By providing an anti-blocking module, when the device is in use, when the raw materials continue to fall into the lower hopper, the impact force generated by the falling raw materials will cause the telescopic spring to stretch downward, thereby driving the L-shaped fixed block and the lower hopper to vibrate, thereby preventing the lower hopper from being blocked due to too much raw materials falling at one time, and preventing the raw materials from being fixedly accumulated in the lower hopper to cause blockage. At the same time, the drive motor is started to make the rotating column run inside the lower hopper, driving the stirring rod and the cleaning soft plate to make circular motion. When blockage occurs, the telescopic rod is started to drive one of the rotating columns to reciprocate in the lower hopper. At this time, a large impact force is generated to decompose the agglomerated raw materials and push the raw materials out of the lower hopper. The stirring rod can disperse the raw materials during the movement to prevent the raw materials from agglomerating and blocking the lower hopper. At the same time, the cleaning soft plate cleans the inner wall of the lower hopper to prevent the raw materials from being accumulated on the inner wall of the lower hopper for a long time, causing the raw materials to accumulate into blocks and block the bottom of the lower hopper.
[0007] In a preferred embodiment, a quantitative module is provided on one side of the extruder body, and the quantitative module includes two support frames, one side of the two support frames is connected to the same fixed frame by bolts, the interior of the fixed frame is fixedly connected to a storage bin, and one side inner wall of the storage bin is fixedly connected to a spiral feeder; one side of the two support frames is fixedly connected to the same limit mounting frame, and the bottom of the limit mounting frame is fixedly connected to a support plate, the interior of the limit mounting frame is movably connected to a quantitative circular plate, the side of the support plate away from the extruder body is fixedly connected to a servo motor, and the driving end of the servo motor is connected to one side of the quantitative circular plate through a coupling; a measuring port is provided on one side of the limit mounting frame, and a weighing machine is fixedly connected to the interior of the measuring port, a feeding port is provided on one side of the limit mounting frame, a feeding pipe is fixedly connected to the interior of the feeding port, and a plurality of feeding troughs are equidistantly provided on one side of the quantitative circular plate.
[0008] By providing a quantitative module, when the device is performing feeding operations, the spiral feeder in the storage bin is started to discharge materials. According to the different remaining amounts of raw materials in the hopper, the weighing device located below the storage bin weighs the raw materials. When the standard is reached, the spiral feeder stops discharging the raw materials, and then the servo motor is used to operate the quantitative circular plate to rotate in the limit mounting frame, so that the filled feeding trough moves to the top of the discharge pipe, and the weighed raw materials enter the hopper. The device uses the quantitative module to intermittently and quantitatively feed the raw materials into the hopper, avoiding the blockage of the hopper and the breakage of the plastic rod caused by the direct one-time feeding of the raw materials, thereby reducing the cost of raw material loss.
[0009] From the above, it can be seen that the feeding warning device for an extruder to prevent plastic rod breakage provided by the utility model adopts a telescopic rod, a rotating column and a cleaning soft plate to be used together to effectively prevent the clogging of the lower hopper due to the agglomeration of raw materials, and uses a quantitative circular plate to make the raw materials fall into the lower hopper intermittently and quantitatively, avoiding the clogging of the lower hopper caused by the raw materials falling all at once, thereby preventing the final extruded plastic rod from breaking.
