Description

Technical Field

[0001] The utility model relates to the technical field of paper cup edge wrapping, in particular to an edge wrapping device for paper cup forming processing. Background Art

[0002] With the development of economy and the continuous improvement of people's living standards, paper cups are used more and more in daily life. Paper cups are made of base paper (white paperboard) made of chemical wood pulp through mechanical processing and bonding. They are cup-shaped in appearance. Paper cups for frozen food are coated with wax, and paper cups for hot drinks are coated with plastic. They can withstand temperatures above 90°C and can even hold boiling water. Edge wrapping for paper cup molding refers to an edge treatment process for the mouth of paper cups during the manufacturing process of paper cups. The purpose of this process is to enhance the structural strength of the mouth of the paper cup, improve the aesthetics, and ensure hygiene and safety during use.

[0003] An existing edge-wrapping equipment for paper cup forming and processing will generate a large amount of heat when it is working continuously. If the heat dissipation design is unreasonable, the internal temperature of the equipment will be too high, which will affect the performance and stability of the equipment and may even cause damage to the equipment. In addition, the paper cup needs to maintain a stable position during the edge-wrapping process. If the fixing force is insufficient, the paper cup may not be firmly fixed on the equipment during the edge-wrapping process, resulting in uneven edge wrapping or misalignment. Conversely, if the fixing force is too great, it may cause unnecessary pressure or deformation to the paper cup, affecting the molding quality and aesthetics of the paper cup.

[0004] Therefore, we proposed a paper cup forming and processing hemming equipment to solve the above problems. Utility Model Content

When the cylinder 3 drives the fixing plate 301 to move downward, it can reduce the impact force, protect the paper cup from damage, and ensure stable fixation. The fixing ring 701 is connected to the inside of the placement groove 201 through the second spring 702. There are four fixing rings 701 and two second springs 702. Two second springs 702 are arranged on the side of each fixing ring 701 away from each other. Through the elastic action of the second spring 702, the fixing ring 701 can fix the paper cup more evenly, provide stable support, and prevent the paper cup from shaking or shifting during processing.

[0029] The hemming unit includes a cylinder 3, a fixed plate 301, a first motor 302, a second connecting strip 303, a limit block 304 and a hemming block 305. The cylinder 3 is fixedly connected to the back of both sides of the upper surface of the workbench 1.

The first motor 302 is set in the middle of the fixed plate 301. The first motor 302 drives the second connecting strip 303 and the hemming block 305 to rotate, and the paper cup is hemmed to achieve the forming process of the paper cup.

[0030] The heat dissipation mechanism includes a bracket 4, a slide groove 1 401, a slide groove 2 402, an electric push rod 403, a slider 1 404, a slider 2 405 and a heat dissipation fan 5. The bottoms of both sides of the bracket 4 are fixedly connected to the rear of the cylinder 3 to support the heat dissipation fan 5 and connect the cylinder 3 to ensure the stability of the heat dissipation mechanism during operation. The slide groove 1 401 is opened on the upper surface of the workbench 1, the slide groove 2 402 is opened on the bracket 4, and the slide groove 1 401 and the slide groove 2 402 are opened opposite to each other. The slider 1 404 and the slider 2 405 are slidably connected to the inside of the slide groove 1 401 and the slide groove 2 402 respectively. The side where the slider 1 404 and the slider 2 405 are close to each other is provided with a heat dissipation fan 5. The right side of the slider 1 404 is fixedly connected with an electric push rod 403 as a power source to push the slider 1 404 to slide in the slide groove 1 401, thereby driving the heat dissipation fan 5 to move.

[0031] Working principle: The paper cup to be processed is placed in the placement groove 201 on the turntable 2. The placement groove 201 provides initial positioning and support for the paper cup, ensuring the initial stability of the paper cup during the processing. Next, the fixing ring 701 is connected to the inside of the placement groove 201 through the second spring 702. Due to the elastic effect of the second spring 702, the fixing ring 701 can fix the paper cup more evenly. When the paper cup is placed in the placement groove 201, the fixing ring 701 will be adaptively adjusted according to the shape and size of the paper cup, and the paper cup is stably supported by the expansion and contraction of the second spring 702. In this way, the paper cup is not easy to shake or shift during the processing. At the same time, the buffer ring 202 is connected to the placement groove 201 through the connecting strip 1 203, and the bottom of the connecting strip 1 203 is movably connected to the upper surface of the placement groove 201. When the cylinder 3 drives the fixing plate 301 and the edge wrapping assembly to move downward for edge wrapping, the buffer ring 202 will be subjected to downward pressure. At this time, the first spring 204 starts to work. Due to its elasticity, the first spring 204 can absorb and reduce the impact force generated when the cylinder 3 is pressed down, thereby protecting the paper cup from damage. When the paper cup is fixed, the cylinder 3 starts to work, pushing the fixed plate 301 and the edge-wrapping assembly thereon to move downward, so that the edge-wrapping block 305 contacts the paper cup. At the same time, the first motor 302 starts to drive the second connecting strip 303 and the edge-wrapping block 305 to rotate, and the paper cup is edge-wrapped.

[0032] During the hemming process, the heat dissipation mechanism pushes the slider 1 404 to slide in the slide 1 401 through the electric push rod 403, thereby driving the heat dissipation fan 5 to move between the slide 1 401 and the slide 2 402. The operation of the heat dissipation fan 5 reduces the temperature inside the equipment, ensuring that the equipment will not be damaged due to overheating during long-term operation. When the paper cup is finished hemming, the turntable 2 continues to rotate and brings the processed paper cup to the removal position. The operator takes out the processed paper cup and places a new paper cup for the next round of processing.
