Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to an adhesive tape with color-coded interval adhesive coating. Background Art

[0002] In traditional packaging technology, full-glue tape is often used for product outer packaging in many industries. In the field of packaging, full-glue means that the entire surface of the tape is evenly coated with glue, and there is no uncoated part. When this kind of tape is pasted, its entire pasting surface will be in close contact with the adhered object to form a comprehensive bond. Full-glue tape usually has strong adhesion and stability, which can ensure the integrity and safety of the product packaging during transportation and storage. However, the full-glue method also has some disadvantages. Since the entire surface of the tape is coated with glue, when the user needs to remove the packaging, it is often difficult to tear off the tape completely, which may cause the outer packaging of the product to be damaged and affect the appearance of the product. In addition, for some packaging surfaces that need to display advertising information or keep clean, full-glue tape may cover these areas, reducing the visual effect and practicality of the packaging.

[0003] In addition, in order to make up for this defect of full-glue tape, many factories choose to use six-sided winding or film wrapping for repeated packaging. Although this method can achieve the effect of protecting the product outer packaging to a certain extent, a large amount of packaging film is wasted, which not only increases the packaging cost, but also reduces the transparency of the product after repeated packaging, and the outer packaging effect is not ideal, which may even reduce consumers' desire to buy. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0036] like Figures 1 to 4 As shown, the utility model provides an adhesive tape with color-coded interval adhesive coating, comprising: a base film 1 as the basic structure of the adhesive tape, used for product outer packaging, having certain waterproof, oil-proof and dust-proof properties;

[0037] The gluing area 2, including the longitudinal gluing area 21 and the transverse gluing area 22, is arranged on the base film 1 and is used for gluing the base film 1 to the product;

[0038] The non-glue area 3 is an area on the base film 1 that is not coated with glue, and is used to protect the product and avoid damage to the product when the outer packaging is torn off;

[0039] The color mark 4 is a colored mark or a QR code set at any position of the base film 1 and is used to identify the position of the adhesive tape.

[0040] The function of the color mark 4 during the machine taping process is to help the machine identify the exact position of the tape, thereby ensuring the accuracy and efficiency of the tape application. Since different manufacturers have different packaging materials, packaging specifications and packaging requirements, the setting of the color mark 4 will also be adjusted accordingly. For example, the color mark 4 can be set in the non-glue area 3, the longitudinal glue area 21 or the transverse glue area 22.

[0041] The position of color scale 4 is highly customizable, such as Figure 1-3 The figure shows the color mark 4 tape at different positions. Whether it is the starting point, the end point or any position in the middle of the tape, the color mark 4 can be set according to actual needs. This flexibility enables the machine to accurately identify the tape position in various complex packaging scenarios.

[0042] The arrangement, size, color, quantity and shape of the color mark 4 are also diverse. Different color mark 4 sensor brands, specifications and models will have different recognition capabilities for color mark 4, so it is necessary to set the appropriate color mark 4 according to the characteristics of the sensor. For example, some sensors may be more sensitive to color marks 4 of specific colors or shapes, so these factors need to be taken into account when setting the color mark 4.

[0043] In practical applications, the color mark 4 can be customized according to the specific needs of the manufacturer. For example, if identification is required on one edge of the tape, a black color mark 4 with a length of 50 mm and a height of 10 mm can be set. If identification is required at multiple points in the middle of the tape, multiple blue color marks 4 with a radius of 20 mm can be set and arranged in a curve.

[0044] like Figure 3 As shown, in one embodiment, the color mark 4 is in the non-adhesive area, the distance L2 from the center of the color mark 4 to the center line of the horizontal adhesive area is 200-400 mm, and the distance L3 from the center of the color mark 4 to the outer edge line of the vertical adhesive area is 100-150 mm. The side length L1 of the color mark 4 is a rectangle of 5-30 mm. The width L6 of the tape is 1200 mm, the width L4 of the horizontal adhesive area is 200 mm, and the width L5 of the vertical adhesive area is 60 mm.

[0045] The proportion of color mark 4 is also an important parameter. It refers to the proportion of color mark 4 in the overall area of ​​the tape. A reasonable proportion of color mark 4 can ensure that the sensor will not miss the color mark 4 because it is too small, nor will it affect the aesthetics of the packaging because the color mark 4 is too large.

[0046] By customizing settings according to different needs, the accuracy and efficiency of tape application can be ensured, thereby improving the automation level of the entire packaging process.

[0047] Since the longitudinal adhesive areas 21 are located on both sides of the base film 1, they can directly and effectively contact the surface of the object to be pasted, thereby ensuring that the tape can be closely attached to the object when pasted and is not easy to fall off. The longitudinal adhesive areas 21 can also enhance the tensile strength and stability of the tape, making it difficult for the tape to break or deform when subjected to tension.

[0048] The horizontal adhesive area 22 is perpendicular to the vertical adhesive area 21, and a plurality of horizontal adhesive areas 22 are arranged at intervals. The main function of the horizontal adhesive area 22 is to enhance the overall stability and pasting effect of the adhesive tape. By arranging the horizontal adhesive area 22 between the vertical adhesive areas 21, a grid-like pasting structure can be formed, which can better disperse the pasting force, making the adhesive tape more uniform and stable during pasting. The horizontal adhesive area 22 can also improve the adaptability of the adhesive tape to irregular surfaces, ensuring that the adhesive tape can maintain a good pasting effect in various complex environments.

[0049] The adhesive-free area 3 is rectangular. The adhesive-free area 3 can prevent the adhesive tape from excessively sticking when pasting, making the adhesive tape more convenient and flexible to use. The rectangular adhesive-free area 3 also makes the adhesive tape more neat and beautiful in appearance. The adhesive-free area 3 can also serve as a positioning mark when the adhesive tape is cut and separated, thereby improving production efficiency and accuracy.

[0050] like Figure 4 As shown, the color mark 4 includes a first color mark 41 and a second color mark 42, and a plurality of first color marks 41 and second color marks 42 are arranged at intervals; the first color mark 41 is a deceleration position, which is used to provide a signal mark for deceleration of the film cutting device.

[0051] When the film cutting device detects the first color mark 41, it will automatically start to decelerate to ensure that the speed has been reduced to a suitable range when it reaches the cutting position. This deceleration design helps to improve the accuracy of cutting and reduce the deviation or error that may be caused by high-speed movement. The deceleration process also helps to protect the blades and other mechanical parts of the film cutting device and extend their service life.

[0052] The second color mark 42 is a stop position, which is used to provide a signal mark for the film cutting device to stop and cut the film.

[0053] When the film cutting device detects the second color mark 42, it will immediately stop moving and cut at the exact position. This design ensures that each cutting can be done accurately at the predetermined position, greatly improving production efficiency and product quality.

[0054] By combining the first color mark 41 and the second color mark 42, the film cutting device can achieve a more accurate and stable cutting operation. It is also possible to set multiple color marks 4 in combination with different devices according to needs to perform different functional combinations. The tape with multiple color marks 4 not only improves work efficiency and reduces production costs, but also reduces the scrap rate caused by human operation or mechanical errors.

[0055] Design and configuration of mold roller. The surface of the mold roller itself is specially designed or processed, and glue application areas can be set on it. When the glue is evenly applied in these areas, as the roller rotates, the glue can be evenly and accurately transferred to the base film 1 to form the required longitudinal glue area 21 and transverse glue area 22.

[0056] Gluing of longitudinal glue area 21: According to the required width of longitudinal glue area 21, glue coating areas 2 of the same width are symmetrically arranged on both sides of the mold roller. These glue coating areas 2 evenly coat glue on both sides of the base film 1 during the rotation of the roller to form longitudinal glue area 21.

[0057] Gluing the horizontal glue area 22: According to the spacing and width requirements of the horizontal glue area 22, adjust the diameter of the middle section of the mold roller to ensure that when the roller rotates, the middle section can be coated with glue at the set interval to form the horizontal glue area 22. The length of the horizontal glue area 22 is set accordingly in the middle section according to the width of the base film 1.

[0058] Color mark 4 setting: Color mark 4 is directly printed or engraved on the mold roller, and maintains a fixed relative position relationship with the horizontal glue area 22 and the vertical glue area 21. The spacing of the color mark 4 and the spacing of the horizontal glue area 22 are both pre-set to fixed values ​​to eliminate position deviations that may be caused by equipment operation accuracy errors.

[0059] Tape gluing and color code 4 production:

[0060] Synchronous operation: When the base film 1 is coated with glue and the color mark 4 is made by the mold roller, ensure that the running speed of the mold roller and the base film 1 are completely consistent, and there is no relative sliding between the two, so as to ensure the accuracy of the glue coating and the printing of the color mark 4.

[0061] Continuous production: The base film 1 passes through the roller continuously. As the roller rotates, the glue coating area 2 evenly applies glue to the corresponding position of the base film 1. At the same time, the color mark 4 is synchronously transferred to the base film 1 to form a tape with the color mark 4 intermittently coated with glue.

[0062] Precise film cutting control:

[0063] Photoelectric sensor detection: During the normal film application process, a photoelectric sensor is used to monitor the passage of the color mark 4 on the tape in real time. When the sensor detects the color mark 4, a signal is sent to trigger subsequent actions.

[0064] Encoder feedback: Equipped with an encoder to accurately measure and record the displacement change of the tape during the pulling process. When the color mark 4 is detected, the encoder provides the actual pulling distance (L+a) at this time, where a is the possible slight deviation.

[0065] Automatic correction of film cutting: When cutting the film for the first time, the system automatically corrects the preset color mark 4 spacing L and the actual feedback distance L+a, and adjusts the target position to La for the next film cutting to ensure that the film cutting position always falls within the horizontal glue area 22. In this way, the system continuously corrects itself to ensure the accuracy of film cutting, ensuring that each film cutting is carried out in the horizontal glue area 22, avoiding mistaken cutting into the glue-free area 3 or affecting the integrity of the vertical glue area 21.

[0066] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
