Description

Technical Field

[0001] This utility model relates to the field of helmet production and processing technology, and in particular to a deburring device for helmet injection molding blanks. Background Technology

[0002] During the injection molding process of helmets, burrs are inevitably generated on the blank. These burrs not only affect the appearance quality of the helmet, but may also cause potential hazards such as scratches to the user. Therefore, deburring the blank used for helmet injection molding is a crucial process.

[0003] Traditional helmet deburring methods rely heavily on manual operation, with operators using simple tools such as sandpaper and knives to remove burrs manually. This method has many drawbacks. On the one hand, manual operation is inefficient and cannot meet the needs of large-scale production, resulting in long production cycles and increased costs. On the other hand, the precision of manual operation is difficult to guarantee, easily leading to incomplete deburring or over-grinding, affecting the stability of product quality.

[0004] With the development of automation technology, some enterprises have begun to adopt simple deburring equipment. However, existing deburring devices still have many shortcomings. Some devices have complex structures and occupy a large space, which limits their installation and use in production workshops with limited space. Some devices have a low degree of automation and still require a lot of manual intervention, such as manually fixing the helmet and adjusting the position of the grinding head. This not only increases the labor intensity of operators but also makes them prone to operational errors due to human factors, reducing production efficiency and product quality.

[0005] Furthermore, existing deburring devices have limited capabilities in handling burrs at different locations and angles on helmets, making precise deburring difficult. For helmet blanks with complex shapes, the processing effect is also unsatisfactory. Simultaneously, the deburring process generates a large amount of plastic dust, and most existing devices lack effective dust collection measures, resulting in a harsh working environment where plastic dust flies everywhere, polluting the environment and seriously endangering the health of operators.

[0006] Furthermore, some parts of the equipment pose safety hazards during helmet loading and unloading operations, requiring operators to work under the grinding head, which increases the risk of accidents. Moreover, during continuous production, the equipment's operational continuity is poor, necessitating frequent shutdowns for loading / unloading and parameter adjustments, thus impacting overall work efficiency.

[0007] Therefore, developing a deburring device for helmet injection molding blanks that is compact, highly automated, capable of precise deburring, effectively collects dust, is safe to use, and has good operational continuity is of great practical significance.

[0008] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0052] Working Principle: First, connect the power supply and connect the air inlet of the external vacuum cleaner to the dust collection pipe 8. Simultaneously, fix the suction pipe on the vacuum cleaner according to actual needs. Then, the operator places the helmet requiring deburring on the turntable 2 and starts motor 1 23. Motor 1 23 controls the rotating sleeve 21 to rotate the turntable 2 via the driving gear 24 and driven gear 22. The turntable 2 rotates the helmet to the deburring range of the grinding head 71. Then, motor 2 3 is started. The output shaft of motor 2 3 drives the drive gear 31 to rotate. Since both toothed plates 32 mesh with the drive gear 31, the two toothed plates 32 drive the two L-shaped plates 33 to move in opposite directions. The two L-shaped plates 33 drive the two clamping plates 34 to clamp and fix the helmet. Then, electric cylinder 4 is started. The working end of electric cylinder 4 drives the mounting frame 41 to descend, causing the U-shaped plate 42 to descend synchronously. At the same time, motors 3 43, 4 52, and 5 63 are started. The output shaft of motor 3 43 drives the U-shaped plate 42 to rotate, and motor 4 52 drives the U-shaped plate 42 to rotate. The worm gear 64 and worm wheel 62 control the rotating shaft 61 to drive the mounting base 6 to rotate around the rotating shaft 61 to adjust the tilt angle of the grinding head 71. The motor 63 moves the horizontal position of the support plate 5 through the lead screw 51 until the grinding head 71 moves to the position where the helmet needs to be deburred. Then, the drive motor 7 is started, and the output shaft of the drive motor 7 drives the grinding head 71 to rotate. The grinding head 71 performs the deburring operation on the helmet. At the same time, the dust collection pipe 8 works with the external vacuum cleaner to perform real-time dust removal to prevent plastic dust from flying everywhere. After the deburring is completed, the electric cylinder 4 controls the grinding head 71 to move upward, and the motor 23, the drive gear 24 and the driven gear 22 work with the rotating sleeve 21 to control the rotation of the turntable 2, so that the processed helmet can be removed from the deburring range. At the same time, another helmet to be deburred is moved into the deburring range. Then, the above operation is continued to achieve continuous deburring operation. After the processed helmet is removed from the deburring range, the operator can take it off.
