Description

Technical Field

[0001] This invention relates to the technical field of food packaging, and in particular to a tape wrapping device for cylindrical packaging. Background Technology

[0002] In the food packaging industry, plastic cylindrical packaging is widely used for packaging various solid, semi-solid, and liquid foods, such as biscuits, candies, milk powder, condiments, and beverage powders, due to its advantages such as light weight, low cost, and ease of molding. To ensure the hygiene, safety, and quality stability of food during storage and transportation, and to prevent moisture absorption, oxidation, or leakage, it is usually necessary to seal the joint between the lid and the body of the cylinder with tape. This process plays a crucial role in ensuring the shelf life of food and maintaining product reputation.

[0003] Currently, most tape wrapping sealing equipment used in the industry is intermittent operation equipment. The basic working principle of this type of equipment is as follows: the plastic cylinder to be sealed is conveyed to the designated wrapping station by the conveying mechanism. Then the conveying mechanism stops running, and the cylinder is fixed in the station by the positioning and clamping mechanism. The wrapping mechanism carries the tape and rotates around the axis of the cylinder, wrapping multiple turns of tape at the joint between the cap and the cylinder body. After wrapping is completed, the clamping mechanism releases the cylinder, and the conveying mechanism restarts to continue conveying the sealed cylinder package forward, while sending the next cylinder to be sealed into the station, and so on in a cycle.

[0004] However, regarding plastic cylinders in the food packaging field, the applicant discovered the following technical problems with the aforementioned intermittent winding equipment in actual use: 1. Plastic cylinders have low strength and insufficient rigidity, making them prone to deformation during intermittent positioning and clamping operations. Existing equipment typically uses cylinder-driven grippers or pressure plates to fix the cylinder in place by applying a certain clamping force. While this clamping method is not significant for metal cylinders, it can easily cause localized dents or deformation in plastic cylinders if the clamping force is too high or the clamping points are concentrated. Deformation not only affects the product's appearance but can also alter the fit between the cap and the cylinder, resulting in loose tape wrapping and compromised sealing. Reducing the clamping force to minimize deformation can cause displacement or rotation of the cylinder during wrapping, leading to misalignment or tape loosening.

[0005] 2. The poor stability of plastic cylindrical packaging during transportation further exacerbates the problems of intermittent operation. Plastic cylinders are lightweight and have a low surface friction coefficient, making them prone to slippage or displacement when the conveyor belt stops and starts. When the cylindrical packaging reaches the winding station requiring precise positioning, the frequent starts and stops of the conveyor system may lead to inaccurate positioning of the cylindrical packaging, affecting the reliability of positioning and clamping. Winding with inaccurate positioning may result in the tape failing to accurately cover the seam between the cap and the cylinder, causing a poor seal.

[0006] 3. The efficiency bottleneck of intermittent operation mode, combined with the characteristics of plastic cylinders, exacerbates the problem. Because plastic cylinders require high clamping force and positioning accuracy, existing equipment often needs to extend the positioning and clamping time to ensure the stability of the cylinder during winding, which further reduces production efficiency. At the same time, frequent start-stop operations place high demands on the stability of the conveying system; however, the lightweight nature of plastic cylinders makes them more sensitive to changes in conveying speed, easily causing swaying or displacement during start-stop operations, increasing the complexity of control.

[0007] In summary, existing intermittent winding equipment for plastic cylinders in the food packaging industry is significantly inadequate in addressing the low strength and easy deformation characteristics of the cylinder material, making it difficult to balance sealing quality, production efficiency, and product appearance.

[0051] The cap is pressed down on the cylindrical packaging by the pressure plate 72. When the cylindrical packaging is rotated, the cap fits against the opening of the cylinder and limits its vertical movement to ensure the adhesion of the tape.

[0052] Furthermore, a limiting block 221 is fixedly provided on the top of the rotating base 22. In this embodiment, the outer contour of the limiting block 221 is an arc shape corresponding to the outer periphery of the cylindrical package.

The movable part of the second positioning drive source 211-3 extends out to abut against the pressure plate 211-2 and drives it to move forward, thereby compressing the spring and moving the second positioning plate 211-1 above the rotating base 22. When the second positioning drive source 211-3 disengages from the pressure plate 211-2, the second positioning plate 211-1 is reset under the action of the spring.

[0060] During operation, the translation base moves to the first end of the working position 11. At this time, the pressure plate 211-2 and the second positioning drive source 211-3 are opposite each other. The first positioning drive source 141 and the second positioning drive source 211-3 simultaneously drive the first positioning plate 142 and the second positioning plate 211-1 to move towards each other in the direction of cylindrical packaging and clamp the cylindrical packaging. This makes the center of the cylindrical packaging concentric with the center of the rotating base 22, ensuring that the cylindrical packaging can make correct contact with the tape pasting device 3 to complete the tape pasting.

[0088] The working principle of this embodiment is as follows: S1. In the initial state, the rotating base 22 is located at the first end of the working position 11 and is used to receive the sealed cylindrical packaging. S2. The pressing drive device 73 drives the cover plate 72 to move vertically downward to press down the cover on the cylindrical packaging; S3, the translation drive source 333 drives the translation frame 332 to move toward the tape supply device 4, so that the second clamping module 334 moves above the output end of the tape supply device 4. Then, the clamping lifting source 336-1 drives the second clamping module 334 to descend and clamp the tape. At the same time, the first clamping module 8 moves to clamp and release the tape. S4. The adsorption stretching source 131 drives the adsorption strip 31 to extend towards the work station.

S5. The second rotary drive source 337 drives the rotary support plate 336 to rotate 90° counterclockwise so that the tape is folded 90° and wrapped around the jaws of the second clamping module 334, so that the tape is not easy to fall off the second clamping module 334 when it is pulled. S6. The translation drive source 333 drives the translation frame 332 to move towards the first end of the working position 11, thereby causing the second clamping module 334 to pull the tape on the tape supply device 4 to the front side of the adsorption strip 31. At the same time, negative pressure is generated at the adsorption hole 311 to adsorb the non-adhesive side of the tape onto the adsorption strip 31. S7.
