Paper cup machine

Abstract

The invention discloses a paper cup machine, which is characterized in that: a multi-position divided turnplate is provided with a main divided turnplate (5) and an auxiliary divided turnplate (25); A sending bottom station (8), a rolling bottom station (10) and a cup bottom knurling station (14) are arranged at the main divided turnplate; a cup cut flanging station and a cup-produced station (24) are arranged on the auxiliary divided turnplate. The paper cup machine is characterized by simple structure, fast production speed and high qualification rate of the products.

Description

【Technical field】 [0001] The invention relates to an improved invention of a paper cup machine. 【Background technique】 [0002] The paper cup machine is a special equipment for the production of disposable paper cups. The paper cup production process includes paper feeding and cutting, cup body forming and cup removal, cup feeding, cup bottom forming, bottom feeding, bottom rolling, cup bottom knurling, cup edge curling Cup bottom forming, bottom feeding, bottom rolling, cup bottom knurling, cup edge curling, cup output and other processes of the existing paper cup machine are coordinated by three multi-station indexing turntables and corresponding mechanisms. , the number of such indexing turntables is large, the structure is complex, the space occupied is large, and its cost is also high. The cup body forming and cup removal mechanism of the existing paper cup machine comprises a cup body bonding mold and a cup hook, and the cup body paper sheets are bonded into a cup bod...

AI Technical Summary

Problems solved by technology

The existing cup bottom knurling mechanism includes a mounting frame, a knurling former, a knurling wheel, a slider, a push rod, a transmission wheel, and a cam. The mounting frame is fixed on the lifting platform, and the mounting frame is connected to the knurling former. The knurling cam and the knurling wheel are set coaxially, and the knurling wheel is set on the slider. The slider has a cavity with a slope, and the slope at the upper end of the ejector rod matches it. The lower end of the ejector rod is connected with the transmission wheel, and the cam passes through the connection. The rod is connected with the ejector rod; when the cup bottom is knurled, the lifting platform reaches the working position (cup bottom knurling position), the cup bottom falls into the knurled pattern, and the cup bottom contacts the knurled pattern. At this time, the cam Action, push the ejector rod upward through the connecting rod, the slope at the upper end of the ejector rod pushes the slider, push the knurled wheel on the slider to the side of the knurled pattern, squeeze the knurled part of the bottom of the paper cup, the knurled pattern and The gap between the knurling wheels directly affects the extrusion pressure, and then the knurling wheels rotate around the center of the knurling master mold driven by the transmission wheel to complete the knurling of the cup bottom. However, the disadvantages of this mechanism are: ①The cam It is not easy to adjust, and the adjustment position deviation of the cam directly affects the size of the gap between the knurling master and the knurling wheel. If the gap is too large or too small, it will affect the extrusion pressure on the bottom of the paper cup and affect the knurling quality;② In order to meet the knurling of the bottom of the cup, when the lifting platform reaches the working position, the bottom of the cup just falls into the knurling pattern, and the lifting platform needs to be adjusted.

The existing cup bottom knurling mechanism and cup mouth curling mechanism are installed on the same lifting platform. The bottom of the paper cup on the multi-station indexing turntable is in contact with the mouth of the cup, and then the bottom of the cup is knurled and the mouth of the cup is curled. Since the bottom of the paper cup and the mouth of the cup have different heights, the stroke of the lifting platform must be at least greater than that of the paper cup. height, so the stroke is large and the speed is slow. Moreover, the knurling mechanism at the bottom of the cup and the crimping mechanism at the mouth of the cup are installed on the same lifting platform. The lifting platform has a heavy load, which makes it noisy and consumes electricity

[0003] To sum up, the existing paper cup machine has the defects of complex structure, large volume, high cost, slow production speed and low product qualification rate
