Description

Technical Field

[0001] The utility model relates to the technical field of production equipment, in particular to a loading machine. Background Art

[0002] At present, during the production process of lipsticks, the empty barrel filling of lipsticks is a crucial link. In the traditional filling process, lipstick empty barrels need to be inserted into corresponding molds one by one before filling for subsequent filling operations. This step mainly relies on manual labor currently, that is, operators need to manually pick up each empty barrel and then accurately insert it into a predetermined position in the mold.

[0003] However, this manual barrel inserting method has several significant problems. First of all, from the perspective of efficiency, the speed of manual barrel inserting is relatively slow. According to existing production data, an operator can only complete the insertion work of about 2,000 lipstick empty barrels per hour. Considering the high-efficiency operation requirements of modern production lines, if the predetermined production line efficiency is to be achieved, at least 5 operators need to be equipped to specifically be responsible for this barrel inserting link. This not only increases the labor cost but also limits the capacity improvement of the entire production line.

[0004] Secondly, the barrel inserting action itself is relatively complex and repetitive, and has relatively high physical requirements for operators. Since they need to maintain concentration for a long time and perform precise operations, operators are prone to fatigue, which not only affects work efficiency but also may increase the risk of operation errors.

The telescopic driving member 26 extends and drives the hollow cylinder clamp 27 to move towards the hollow cylinder mold 40. The hollow cylinder 50 is inserted into the positioning hole 41. The clamp driving member 33 controls the first clamping plate 28 and the second clamping plate 30 to move away from each other, releasing the clamping of the hollow cylinder 50, so that the hollow cylinder 50 is placed in the positioning hole 41, realizing the automatic placement of the hollow cylinder 50 on the hollow cylinder mold 40.

The adjacent limiting rods 18 define a limiting material channel 16. When the empty cylinder 50 is placed in the limiting material channel 16, the position of the empty cylinder 50 is limited by the limiting material channel 16. One end of the empty cylinder 50 faces the flip hole 12, so that the empty cylinder 50 can be accurately inserted into the flip hole 12 under the push of the transmission belt 15, thereby improving the accuracy of the empty cylinder 50 being inserted into the flip hole 12.

[0043] As one embodiment, Figure 1 and Figure 4 As shown, the side of the limiting rod 18 away from the transmission belt 15 is connected to the limiting plate 19, and the limiting plate 19 increases the height of the limiting channel 16, so that the empty cylinder 50 can be placed more accurately in one of the limiting channels 16 when placed, avoiding the empty cylinder 50 from being placed across the channel. As one embodiment, the height of the limiting plate 19 is greater than the diameter of the empty cylinder 50.

[0044] Furthermore, the flip bracket 13 is connected to a flip motor, which is in transmission connection with the flip shaft 11.
