Description

Technical Field

[0001] The present application relates to the field of mechanical processing equipment, and in particular to a device for internally cutting the length of a glass bulb. Background Art

[0002] In the actual manufacturing process, the length of the glass shell is not standard, and there are scraps at both ends of the glass shell. The glass shell needs to be cut into glass shells that meet the specification length. Traditional glass tubes and glass shells are cut by electric heating wire cutting and outer circle scoring cutting, but both of these two cutting methods have certain defects. When cutting the glass shell, it is affected by the stress of the glass shell itself, and the cutting is uneven or even broken, causing the entire product to be scrapped and increasing the defective rate.

[0003] The utility model patent with patent application publication number CN209740994U discloses a device for internally cutting the length of a glass bulb, comprising a bottom plate, support seats are symmetrically arranged on the left and right sides of the bottom plate, guide pillars and studs are arranged on the sides of the two support seats close to each other, the guide pillars are in two groups, and the two groups of guide pillars are parallel to each other, a driving plate is slidably connected to the two groups of mutually parallel guide pillars, and the driving plate is threadedly connected to the studs through threaded holes, a hand wheel is arranged on the right end of the stud, and two adjusting guide pillars are arranged on the upper surface of the driving plate, and a pressure block and a positioning block are arranged on the circumferential surfaces of the two adjusting guide pillars from bottom to top in sequence, and the two pressure blocks are connected to the driving plate through a fixing wire. The device for internally cutting the length of a glass bulb can play a very convenient role in cutting the length of the glass bulb, is suitable for cutting glass bulbs of different lengths and sizes, can accurately cut the length of the glass bulb, has good length consistency, uses internal cutting to prevent the bursting of the glass bulb, reduces the defective rate, and improves product quality.

[0004] However, the above device still has some disadvantages in actual use. The most obvious one is that although it can change and adjust the position of the cutting knife, it cannot rotate the cutting knife, and can only rotate the glass shell, which may cause the position of the glass shell to change, resulting in irregular subsequent cutting and incomplete cutting of the glass shell.

[0005] Therefore, it is necessary to invent a device for cutting the length of the glass bulb internally to solve the above problems. Utility Model Content
