Paper cup and paper cup machine

Abstract

The invention relates to the field of paper cup production. A paper cup machine comprises a workbench, a cup bottom punching device, a jig conveying device, a cup cylinder paper feeding device, a cupbottom machining device and an edge curling device, wherein the cup bottom punching device, the jig conveying device, the cup cylinder paper feeding device, the cup bottom machining device and the edge curling device are fixed to the workbench; corresponding stations of the jig conveying device are connected with the discharging end of the cup bottom punching device, the discharging end of the cupcylinder paper feeding device, the discharging end of the cup bottom machining device and the feeding end of the edge curling device; the cup bottom punching device is used for punching the cup bottom of a paper cup; the jig conveying device is used for conveying in the paper cup machining process; the cup cylinder paper feeding device is used for feeding and machining cup cylinders; the cup bottom machining device is used for bottom folding, bottom rolling and knurling of the cup bottom of the paper cup; and the edge curling device is used for edge curling of the mouth of the paper cup. According to the paper cup and the paper cup machine, by arranging the cup bottom punching device, the jig conveying device, the cup cylinder paper feeding device, the cup bottom machining device and theedge curling device, automatic machining and circulation of paper cups are achieved, and the automation degree of the whole equipment is improved.

Description

technical field [0001] The invention relates to the field of paper cup production, in particular to a paper cup machine. Background technique [0002] The paper cup machine is a kind of equipment used to produce the base paper made of chemical wood pulp for mechanical processing and bonding to make paper containers. The paper cups produced by the paper cup machine are cup-shaped and can be used for frozen food and hot drinks. At the same time, the paper cups produced by the paper cup machine are safe, hygienic, lightweight and convenient, and their low price can meet the needs of most consumers. After use, they are conducive to environmental protection. They are ideal drinking utensils for public places, restaurants and restaurants. When the paper cup machine produces paper cups, if there are quality problems such as poor bonding or improper assembly of the bottom of the cup tube, it will cause the bottom of the produced paper cup to fall off or even cause burns. Therefore...

Problems solved by technology

[0004] The prior art has the following deficiencies: 1. When assembling paper cups, each process is completed manually on a single workbench, and then the product flow is sent to the next workbench through the conveyor line for the next process, and finally the entire cup is completed. Box heat shrinkable film packaging process; and each process requires manual participation and auxiliary feeding flow, which affects the processing efficiency of the entire device and results in a low degree of automation of the entire equipment

3. When the paper cup is transported to the crimping device, the paper cup push rod in the jig conveying device pushes the paper cup fitted outside the paper cup positioning jig from the inner side of the paper cup to the inner hole of the paper cup receiving jig in the crimping device to complete the paper cup The conveying process; while the paper cup is hollow and easy to deform, when the paper cup push rod will push the stationary paper cup from the inside of the paper cup, the thrust of the moving paper cup push rod will cause the paper cup to expand and deform, and the gap between the paper cup push rod and the stationary paper cup Relative movement is generated to further displace the bottom of the paper cup; while the diameter of the bottom of the tapered paper cup is smaller than the diameter of the pushing part of the paper cup push rod, that is, the displaced paper cup push rod will expand and expand the paper cup at the pushing place to receive the pressing force of the paper cup at the pushing place; When the paper cup pusher pushes the paper cup to the crimping device and then retracts to the initial position, the expanded paper cup will move backwards with the retraction of the paper cup pusher due to the pulling force of the paper cup pusher, resulting in inaccurate delivery position of the paper cup

4. When feeding the cup tube paper, first use the paper suction cylinder to drive the paper suction mechanism to absorb the cup tube paper in the cup tube paper feeding mechanism to the paper feeding frame, and then push the cup tube paper to drive the cylinder to drive the paper pushing mechanism to The cup tube paper is pushed out to complete the cup tube paper feeding process; while the paper suction process and the paper push process of the cup tube paper require two driving mechanisms, the paper suction cylinder and the cup tube paper pushing cylinder, to increase the number of driving mechanisms; at the same time, When the cup tube paper is pushed by the cylinder to push the cup tube paper to be loaded, one cup tube paper is pushed out at a time, then retracted and then pushed to the next one; The time for feeding the cup paper will increase a lot, which is not conducive to the rapid feeding of the cup paper

5. When forming the cup tube into a paper cup tube, use two push-up cylinders to push the two pieces of forming fixtures together to form the cup tube into a paper cup tube to complete the forming process of the cup tube; while the accuracy of the cylinder is poor , when the push-up cylinder is used for a period of time, there will be a gap between the cylinder push shaft and the cylinder body, which will cause the cylinder push shaft to deviate from the previous position after being extended; thus causing the forming fixture to deviate from the previous forming position, which will not Conducive to the precise forming of cup tube paper
