Description

Technical Field

[0002] During the paper cup or paper bowl forming process, the paper sheet is fed into the paper tube forming mechanism for paper tube forming. During the paper tube forming process, the paper sheet under the forming mold is enclosed on the forming mold by the cup clamp below at the forming station. The paper sheet is enclosed and overlapped to form a paper tube. Then, the enclosed and overlapped parts of the paper sheet on the forming mold are bonded by the ultrasonic wave above. After the paper tube is formed, the paper tube is taken out from the forming mold and conveyed forward to other mechanisms in the subsequent forming equipment for other processing steps.

[0003] After checking the publication number: CN107756871A, a paper tube forming mechanism is disclosed. This technology discloses "a paper tube forming mechanism, including a forming mold, a demoulding device and an auxiliary forming device, the demoulding device includes a demoulding head for demoulding, the demoulding head is connected to the demoulding transmission device, the demoulding head is driven by the demoulding transmission device to move the paper tube on the forming mold forward into the auxiliary forming device, the auxiliary forming device includes a core bracket and a top bracket, and the core bracket is located in front of the forming mold" and other technical solutions, which have "by adding an auxiliary forming device to extend the bonding time of the paper tube, after the ultrasonic wave is used to bond the paper tube enclosed on the forming mold, the paper tube can also be clamped in the auxiliary forming device for further bonding, and the bonding time is extended and more firm. Secondly, the auxiliary forming device applies pressure to the enclosed connection when clamping the paper tube, thereby improving the roundness of the paper tube. Moreover, the paper tube is clamped in the auxiliary forming device and can be conveyed forward" and other technical effects;

[0004] In the above production process, once the paper cups are manufactured, they are usually stacked and collected by a cup sorting machine for subsequent packaging. However, on a high-speed production line, if a robotic arm is used to grab the paper cups, it may not be able to keep up with the production rhythm due to the limited grabbing speed of the robotic arm, which will have an adverse effect on the overall production efficiency. On the other hand, if the paper cups are automatically slid down, given that the paper cups are light and have a certain elasticity, they may not be smoothly and completely inserted into the paper cups below, which will directly affect the neatness and stability of the stacking.

Multiple paper cups are stacked according to a preset number. When the stacked paper cups reach the preset number, the movable cup rack is driven downward by the long-range cylinder, so that the stacked paper cups inside are dumped; and then the stacked paper cups are separated from the movable cup rack by the discharge assembly and rolled into the hopper, so that the stacked paper cups can be taken out for the next process.

When the stacking reaches the preset number, the long-range cylinder drives the movable cup rack to flip downward to a horizontal position, and the stacked paper cups and the movable cup rack are tilted downward together, and then the stacked paper cups are separated from the movable cup rack by the discharging assembly and rolled into the hopper, so that the stacked paper cups can be taken out for the next process; by using vacuum to utilize the air pressure difference to achieve rapid and continuous conveying of paper cups, it can match the rhythm of high-speed production lines; and, because there is a force provided by air pressure during the conveying and stacking process, it can ensure that the upper paper cup is fully inserted into the lower paper cup, so that they can be neatly stacked together, which improves the stability of the stacking.

[0022] 2. The output end of the first double-axis cylinder extends out a driving bevel block, which cooperates with the guide wheel to push the shaft arm to flip inward, so that the stopper on the shaft arm is embedded in the feed port, thereby preventing the paper cups in the feed port from falling down; similarly, the output end of the first double-axis cylinder contracts and drives the bevel block to disengage from the guide wheel, and the pressure of the torsion spring rebound pushes the shaft arm to flip outward, and the stopper on the shaft arm is separated from the feed port, so that the paper cups in the feed port can fall down; oblique paper suction is more stable, less prone to paper jams, and more suitable for high-speed operation of the equipment, which greatly improves the efficiency of the product.

The turntable is driven by a reduction servo motor to drive the mold assembly to rotate; the air tank stores the air source of the blower through the air pipe, and then disperses it to three hot air guns. The paper cups on the mold assembly pass through the three hot air guns in turn to achieve the bonding of the cup bottom; three hot air heating and bonding, the air duct is shortened, the stability of the air source is improved, the temperature difference is reduced, it is more stable, the chance of water seepage in the paper cup is reduced, and the yield rate is further improved.

A servo paper cup machine manufacturing process according to any one of claims 1-7, characterized in that: The following steps are involved: S1: First, a paper sheet for making a cup body is transported to a machine body (1) by a feeding mechanism (5), and then the paper sheet is adsorbed and grasped by a picking mechanism (3) and sent to a cup body forming mechanism (6), and the cup body forming mechanism (6) cooperates with an ultrasonic device to process the paper sheet into a cup body; S2: At the same time, the roll paper for making the cup bottom is transported to the cup bottom forming mechanism (11) through the roll mechanism (9) in cooperation with the pre-feeding mechanism (10) for cutting and forming, and the cut waste is discharged from the discharge mechanism (12); then, the formed cup body and cup bottom enter the work station mechanism (4), and the cup body and cup bottom are bonded after heating, and the knurling and bottom knurling are carried out through the knurling and bottom rolling mechanism (7); and the mouth rolling is then carried out through the mouth rolling mechanism (8), thereby completing the forming of the paper cup; S3: Finally, the air in the pipe (218) is extracted by a vacuum pump, and the formed paper cups are transported to the feed port (214) through the pipe (218), and then fall between the static cup rack (215) and the movable cup rack (216), and a plurality of paper cups are stacked according to a preset number. When the stacked paper cups reach the preset number, the movable cup rack (216) is driven downward by the long-stroke cylinder (217), so that the stacked paper cups are dumped therewith; and the stacked paper cups are separated from the movable cup rack (216) by the discharge assembly (23) and rolled into the hopper (212), so that the stacked paper cups can be taken out for the next process.
