Cup with cover and sealing machine for cup with cover

Abstract

The invention discloses a cup with a cover and a sealing machine for the cup with the cover. An upper mold is installed on a supporting assembly and provided with an ultrasonic transducer, during sealing, the upper mold descends to work in cooperation with a lower mold, and therefore the cup cover and a cup body can be subjected to ultrasonic welding. Compared with the prior art, the cup has the advantages that the cup body and the cup cover can be quickly bonded; preheating is not needed, the speed is high, and safety is higher; and a reciprocating feeding device and a lifting driving device are matched to work, so that continuous work can be realized, and the working efficiency is improved. Compared with the prior art, the cup with the cover has the advantages that an initial sealing state is achieved, the cup is sanitary and convenient to transport, the cup cover can be repeatedly opened and covered, one-time drinking is not needed, splashing is not prone to occurring, and the requirements of merchants and vast consumers are met.

Description

technical field [0001] The invention relates to the technical field of disposable cup processing, in particular to a cup with a lid and a cup sealing machine with a lid. Background technique [0002] With the improvement of people's living standards, fresh drinks in cups, such as fresh fruit juice and hot soybean milk, are becoming more and more popular. Most businesses use semi-automatic sealing machines for sealing operations. The plastic cup sealing machine in the prior art is mainly used in the hot-melt connection between the cup body and the film. The main principle is to preheat the heat-sealing plate (electric heating plate) to a certain temperature by electrifying it, and then press the heat-sealing plate against the film. (mainly PP film and PE film) in contact with the cup body (cups such as figure 1 As mentioned above), the heat-sealed plate is removed immediately after the film is heated and melted and bonded to the cup body. This technology is widely used in fa...

Problems solved by technology

Yet the cup sealing machine of prior art can only be applied to the film sealing of cup, and can not be applied to the bonding of thicker plastic cover, paper cup cover or other non-plastic film cup cover and cup body, wherein, for thicker Plastic cover (refer to figure 2 As shown), the temperature of ordinary sealed cups is not enough to melt the plastic cover. If the power of the electric heating plate is increased, it will appear that when the heat sealing plate is pressed against the plastic cover, the upper part of the plastic cover and the heat sealing plate will melt instantly. It is in a liquid state and the lower part is still in an unmelted and non-sticky state. At this time, the plastic cover will be bonded to the heat-sealing plate instead of the cup body, and the melted plastic will form multiple tiny balls when it cools and condenses again. Unsightly and easy to drop

For the paper cup lid, because the paper cup lid is thicker and the paper material has a certain degree of heat insulation, the outer paper layer will block the heat of the heat sealing plate from being transferred to the coating layer inside the cup lid to a certain extent, so that the coating layer cannot be partially heated and melted. Fused with the cup body, the plastic sealing cups of the prior art cannot realize the bonding between the paper cup and the paper cup lid, and cannot solve the problem that the paper lid and the paper cup lid cannot be tightly closed directly
