Abstract

A carton-shaping machine includes a material conveying mechanism, an opening mechanism, a shaping mechanism, and a band sticking mechanism combined on a worktable. A vertical and a horizontal cylinder of the opening mechanism control fixing members to force needles on them insert firmly in an upper folding portion of a carton and turn the carton to extend to standing position so as to permit opening process operated with accuracy. Then, the band sticking mechanism may seal the bottom portion of the carton and the carton is moved to the packing process, without any need of manual work to turn it for a right angle to stand upright.

Claims

1. A carton-shaping machine comprising a material conveying mechanism, an opening mechanism, a shaping mechanism and a band sticking mechanism combined on a worktable;

said material conveying mechanism having a material support frame located slopingly perpendicular to an operation direction on said worktable, a vertical conveyer belt fixed on a center portion of said material support frame located perpendicular to said operation direction of said shaping machine, a push plate located above said vertical conveyer belt, a guide frame respectively located at two sides of said push plate and above said material support frame, an upper base located at an upper end of said vertical conveyer belt and on said worktable, and a horizontal conveyer wheel unit for driving two chains respectively located above and below said upper base to convey a vertically arranged carton in said operation direction;

said shaping mechanism having a first and a second pressure cylinder located horizontal below said opening mechanism for controlling respectively a front and a rear push member, a left and a right pressure cylinder located at two sides of said first and said second pressure cylinder for moving a side push member, a rail located between said two side push members for a slide base to lie and move thereon, and a vertical push rod fixed on said slide base;

said band sticking mechanism located behind said shaping mechanism, having a side conveyer belt respectively located at two longitudinal sides on said worktable, a roller unit located between said two side conveyer belts, and a band sticker at a rear portion of said band sticking mechanism;

said opening mechanism located behind said meterial conveying mechanism, having a vertical control cylinder for controlling a fixing member in vertical movement, a plurality of needle bases with a downward needle fixed on said fixing member, a small fixing member pivotally connected to said fixing member with a pivot shaft, said small fixing member having a needle base fixed on its front side, a horizontal control cylinder located behind said fixing member, wherein needles of said needle bases inserting in an upper folding portion of a carton when said opening mechanism is operating for opening said upper folding portion of said carton in standing position.

2. The carton-shaping machine as claimed in claim 1, wherein said two chains of said material conveying mechanism have a plurality of needle bases corresponding to each other to position the upper and the lower end of side portions of a carton.

3. The carton-shaping machine as claimed in claim 1, wherein said needle bases respectively have a three-fork needle or a plate needle extending downward.
