Description

Technical Field

[0001] This utility model belongs to the field of bottle manufacturing, and specifically relates to a bottle mouth trimming device. Background Technology

[0002] In the traditional bottle manufacturing process, heat treatment, welding and cutting operations in the processing technology will generate stress, which will cause dimensional changes; in terms of materials, shrinkage or expansion of materials may also cause deviations in product dimensions.

[0003] At the same time, if problems such as tool wear, loose fixtures, and machining center misalignment are not addressed in a timely manner, the manufactured products are prone to dimensional instability, resulting in uneven bottle mouth surfaces and unstable bottle neck heights.

[0004] Therefore, there is an urgent need to design a new type of bottle mouth correction device to solve the above problems. Utility Model Content

[0006] Technical Solution: To achieve the above objectives, this utility model provides a bottle neck trimming device, including a conveyor unit, a clamping mechanism, a frame, a longitudinal displacement mechanism, a bottle neck trimming mechanism, and a cleaning mechanism; the clamping mechanism is located on both sides of the conveyor frame; the frame is located on one side of the conveyor unit; the longitudinal displacement mechanism is located on the frame; the bottle neck trimming mechanism is connected to the longitudinal displacement mechanism and is located above the conveyor belt of the conveyor unit; the bottle neck trimming mechanism includes a bottle neck trimming transmission assembly, a cutter disc, and cutter particles; the bottle neck trimming transmission assembly is connected to the longitudinal displacement mechanism and is located above the conveyor belt of the conveyor unit; the cutter disc is located at the lower end of the bottle neck trimming transmission assembly; the lower part of the cutter disc has a notch; the cutter particles are located in the lower notch of the cutter disc and are connected to the cutter disc by screws; the cleaning mechanism is located beside the conveyor unit; the cleaning mechanism includes an outer cover, which is located outside the cutter disc and below the bottle neck trimming transmission assembly.

[0007] Furthermore, the conveyor unit is used for conveying bottles, the clamping mechanism ensures the stability of bottle clamping during the bottle neck repair process, and the frame provides installation support for the longitudinal displacement mechanism and the bottle neck repair mechanism; after the longitudinal displacement mechanism drives the bottle neck repair mechanism to adjust the height of the bottle neck, the bottle neck repair mechanism performs the bottle neck repair; during the repair process, the waste material is inside the outer cover and is cleaned by the cleaning mechanism.

[0008] Furthermore, the lower end of the cutting blade extends beyond the lower surface of the cutter head. The cutting blade rotates with the cutter head, and cutting is performed by the cutting blade extending beyond the lower surface of the cutter head.
