Description

Paper cup and paper cup machine

Technical Field

The invention relates to the field of paper cup production, in particular to a paper cup machine.

Background

The paper cup machine is a device for producing paper containers which are made by mechanically processing and bonding base paper made of chemical wood pulp. The paper cup produced by the paper cup machine is cup-shaped in appearance and can be used for frozen foods and hot drinks. Meanwhile, the paper cup produced by the paper cup machine has the characteristics of safety, sanitation, lightness, convenience and the like, has low price, can meet the requirements of most consumers, is favorable for environmental protection after being used, and is an ideal drinking tool for public places, restaurants and dining rooms. And if the paper cup machine has the quality problems of weak bonding or improper assembly of the cup bottom of the cup cylinder and the like during the production of the paper cup, the produced paper cup bottom of the paper cup can fall off or even be scalded by personnel. Therefore, the equipment performance of the paper cup machine is very important for paper cup processing.

The patent name of the paper cup machine is CN101391493B, and the paper cup machine comprises a frame, a cup body paper feeding mechanism, a cup barrel forming mechanism, a cup barrel feeding mechanism, an indexing turntable, a cup bottom paper feeding mechanism, a transmission mechanism, a bottom feeding station, a cup receiving station, a heating station, a bottom folding station, a bottom rolling station, a mouth rolling station and a cup discharging station, wherein corresponding working mechanisms are arranged at each station; the paper cup machine is only provided with an indexing turntable, and the bottom conveying station, the cup receiving station, the heating station, the bottom folding station, the bottom rolling station, the mouth rolling station and the cup discharging station are arranged on the indexing turntable. The paper cup machine has the advantages of simple structure, high speed, stable operation and low and high speed. Meanwhile, the manufacturing cost of the die is reduced, the manufacturing period of the die is shortened, the failure rate of the equipment is reduced, the maintenance difficulty and cost are reduced, and the equipment is easier to operate.

The prior art has the following defects: 1. when the paper cup is assembled, each process is independently finished on a single workbench by manual work, and then the product is conveyed to the next workbench by a conveying line for processing of the next process, and finally the whole thermal shrinkage film packaging process of the mobile phone box is finished; and each process needs the manual work to participate in and assist the unloading circulation when processing, influences the machining efficiency of whole device to cause whole equipment's degree of automation to be lower. 2. When the cup bottom is punched and pushed, firstly, a punching cylinder is adopted to drive a punching head to punch the cup bottom, and then a pushing cylinder drives a pushing head to push the punched cup bottom to a jig conveying device; and the quantity of the driving devices is increased by respectively adopting two different cylinders for driving during punching and pushing, and then the two cylinders of the punching cylinder and the pushing cylinder need to be respectively controlled, so that the complexity of controlling the driving devices is increased. 3. When the paper cup is conveyed to the crimping device, a paper cup push rod in the tool conveying device pushes the paper cup embedded outside the paper cup positioning tool from the inner side of the paper cup to an inner hole of a paper cup receiving tool in the crimping device to complete the paper cup conveying process; the paper cup is in a hollow structure and is easy to deform, when the paper cup push rod pushes the static paper cup out from the inner side of the paper cup, the paper cup can expand and deform by the pushing force of the moving paper cup push rod, and relative movement is generated between the paper cup push rod and the static paper cup to further displace towards the bottom of the paper cup; the diameter of the bottom of the conical paper cup is smaller than that of the pushing part of the paper cup push rod, namely, the pushed paper cup is expanded by the displaced paper cup push rod so as to be pressed by the pushed paper cup; when the paper cup push rod retracts to the initial position after pushing the paper cup to the crimping device, the expanded paper cup is stretched due to the fact that the paper cup push rod pulls to retract to move backwards along with the paper cup push rod, and therefore conveying positions of the paper cup are not accurate. 4. When the paper cup is fed, the paper suction cylinder drives the paper suction mechanism to suck the paper cup in the paper cup feeding mechanism to the paper feeding frame, and then the paper cup pushing cylinder drives the paper pushing mechanism to push the paper cup out to complete the paper cup feeding process; the paper suction process and the paper pushing process of the paper cup are respectively required to be carried out by two driving mechanisms of the paper suction cylinder and the paper cup pushing cylinder, so that the number of the driving mechanisms is increased; meanwhile, when the paper cup pushing cylinder pushes the paper cup to be fed, the paper cup pushing cylinder pushes one paper cup at a time, and then retracts to push the next paper cup; when the distance between the initial position and the paper cup feeding position is long, the time for pushing one piece of paper cup to be fed is increased more, so that the quick feeding of the paper cup is not facilitated. 5. When the cup tube paper is formed into the paper cup tube, two push-up air cylinders are adopted to respectively push two forming jigs to be folded to form the cup tube paper into the paper cup tube, so that the forming process of the cup tube paper is completed; the pushing accuracy of the cylinder is poor, and when the pushing cylinder is used for a period of time, a gap is easily generated between the pushing shaft of the cylinder and the cylinder body, so that the pushing shaft of the cylinder extends out and then deviates to the front position; therefore, the forming jig is deviated from the former forming position, which is not beneficial to the accurate forming of the cone paper.
