Mechanism capable of preventing cups from falling off of vertical paper cup or paper bowl forming device

Abstract

The invention discloses a mechanism capable of preventing cups from falling off of a vertical paper cup or paper bowl forming device. According to the mechanism, cup molds are vertically arranged on a rotary disc, and the rotary disc intermittently rotates in an indexing mode; a clamping device capable of preventing the cups from falling off comprises clamping blocks and a transmission device; the clamping blocks and the cup molds keep rotating synchronously; the clamping blocks reciprocate to be coordinated with the corresponding cup molds so as to clamp and release the cups; under the working condition, the clamping blocks between cup feeding stations and cup discharging stations keep a clamping operation state; cup bodies are clamped on the cup molds so that the phenomenon that the cups accidentally fall off from the cup molds due to the fact that the cups are heated and stressed in the forming process, and then the forming is affected can be avoided; particularly, when the cone angle of each cup body exceeds 8 degrees, the self-locking capacity of the cup bodies on the cup molds is reduced, and the cup bodies are particularly prone to fall off after being affected, paper cups or paper bowls with the cone angles of which exceeding 8 degrees can be clamped by the clamping device capable of preventing the cups from falling off, and can be formed and produced; and rolling wheels roll on driving cams and are coordinated with reset springs so that lifting of the clamping blocks can be realized, and the clamping blocks and the cup molds can be in a clamped state and in a separated state. The mechanism capable of preventing the cups from falling off has the advantages that the mechanical performance is good, the operation is more stable, the high-speed requirement can be met, the fault rate is low, and the maintenance is convenient.

Description

technical field [0001] The invention relates to paper cup or paper bowl production equipment, in particular to vertical paper cup or paper bowl forming equipment. Background technique [0002] Vertical paper cup or paper bowl forming equipment, such as vertical paper cup or paper bowl forming machine, its cup molds are distributed vertically on the turntable, the cup molds are set in equal parts, and the cup molds perform intermittent indexing rotation along with the turntable. The radial position of the turntable remains relatively unchanged, and the cup mold is used for molding. The die-cut fan (paper) is rolled and glued into a cup tube, and the cup tube is sent upwards to the vertical cup mold at the upper cup station, and the cup tube will be placed outside the cup mold further shaping. The turntable drives the cup mold to pass through the cup loading station, the cup bottom preheating station 1, the cup bottom preheating station 2, the cup bottom rolling station, the...

Problems solved by technology

However, the self-locking state is affected by the cone angle of the cup mold. When the cone angle exceeds 8 degrees, the radial effective component force of the static pressure decreases, the static friction force decreases, and the self-locking force decreases, resulting in an unstable self-locking state. It will fall off from the cup mold during the subsequent preheating, bottom rolling, knurling and other forming stations, resulting in forming failures and unable to perform normal forming production
