Description

Technical Field

[0001] The present application relates to the field of die-cutting processing technology, and in particular to a padding foam striping and composite process and a sticker product. Background Art

[0002] Existing sticker products usually have a padding foam compounded between the adhesive surface and the release surface. Because the padding foam is thicker, it can absorb the tension of the sticker product when it is rolled up, solving the problem that the adhesive surface and the release surface cannot be separated. The existing padding foam stripping and compounding process usually involves compounding the padding foam, double-sided tape and collagen paper into several narrow strips, and then using several roll cores with baffles on both sides to roll up each narrow strip. Then, the narrow strip is taken out as needed, and the collagen paper is peeled off to expose the adhesive surface and then compounded with the release surface to obtain the final sticker product. The existing process requires the use of a bottom low-viscosity film for lining the knife during cutting. 15 to 20 sets of roll cores with baffles on both sides are required for the rolling of narrow strips. It is also easy to explode and flip the material during rolling, and it is also easy to break the narrow strip when the collagen paper is peeled off. Therefore, how to reduce the frequency of abnormalities during processing, improve processing efficiency and save materials are technical problems that need to be solved urgently.

[0044] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0045] Reference Figure 1 As shown, the present application provides a padding foam striping and compounding process, which is applied to padding foam striping and compounding equipment. The padding foam striping and compounding process includes but is not limited to step S110, step S120, step S130, step S140, step S150 and step S160:

[0046] Step S110: providing a cushioning foam material and a bottom supporting film;

[0047] Step S120: Compounding and cutting the padding foam material and the bottom support film to obtain a first combined material strip; wherein the cutting depth of the cutting and stripping process matches the thickness of the padding foam material, so that the padding foam material is cut into a plurality of strips of padding foam;

[0048] Step S130: performing a whole-page rolling process on the first combined material strip to obtain a first product;

[0049] Step S140: Separate the first product to obtain strip-shaped padding foam;

[0050] Step S150: providing a release film and a strip-shaped adhesive film; wherein the number of the strip-shaped adhesive film and the strip-shaped padding foam matches;

[0051] Step S160: Compounding the release film, the strip-shaped adhesive film and the strip-shaped raised foam to obtain a second product; wherein the strip-shaped adhesive film is located between the strip-shaped raised foam and the release film.

[0052] Steps S110, S120, S130, S140, S150, and S160 shown in the embodiment of the present application save materials by only cutting the raw material of the padding foam and using a bottom film lining knife. By rolling up the first combined material strip in its entirety, the materials and time required for rolling up are saved. At the same time, the first product after the entirety of the rolling up is wider, which reduces the risk of bursting and material flipping, and reduces the frequency of abnormalities. By separating the first product to obtain strip-shaped padding foam, and then compounding it with a release film and a strip-shaped adhesive film, the frequency of abnormalities is reduced and the compounding efficiency is improved. Compared with the prior art, the embodiment of the present application can reduce the frequency of abnormalities during processing, improve processing efficiency, and save materials.

[0053] It is understandable that the padding foam stripping and compounding equipment includes a pressing and cutting equipment, and the pressing and cutting equipment includes a pressing station and a cutting station, the pressing station is provided with a pressing roller, and the cutting station is provided with a stripping knife; Figure 1 , 2 As shown, step S120 also includes but is not limited to step S210 and step S220:

[0054] Step S210: transporting the padding foam raw material and the bottom supporting film to a pressing station, controlling the pressing roller to press the padding foam raw material and the bottom supporting film to obtain a second combined material strip, wherein the padding foam raw material is located above the bottom supporting film;

[0055] Step S220: transport the second combined material strip to the cutting station, control the slitting knife to cut the raised foam raw material, and obtain the first combined material strip.

[0056] In the step S210 and step S220 shown in the embodiment of the present application, the padding foam raw material and the bottom film are pressed together to ensure that the two are tightly combined, providing higher quality raw materials for subsequent processing. The padding foam raw material is accurately cut using a slitting knife to ensure cutting depth and accuracy, reduce material waste, and improve production efficiency.

[0057] In some embodiments, the padding foam raw material and the bottom film are transported to the lamination station. At this time, the lamination roller precisely presses the two. The lamination roller ensures the close combination of the padding foam raw material and the bottom film by adjusting the pressure and speed control. In order to ensure the composite effect, the padding foam raw material is always located above the bottom film to ensure that the connection between the foam and the film is firm and uniform. The lamination roller is adjusted according to the thickness and characteristics of the material to ensure that the material is not damaged. During the lamination process, the temperature and pressure parameters are also optimized and adjusted according to the requirements of different materials. By precisely controlling the lamination force, the composite effect between the padding foam raw material and the bottom film is ensured to be good, and the occurrence of bubbles, wrinkles or unevenness is avoided, providing a stable foundation for subsequent cutting and processing. Next, the second combined material strip that has been laminated is transported to the cutting station. The cutting station is equipped with a precise slitting knife that can finely cut the padding foam raw material according to the set cutting depth and spacing. The depth setting of the cutting tool is perfectly matched with the thickness of the raw material of the padding foam, thus ensuring that the cutting size of each strip of padding foam is accurate. During the cutting process, the movement speed and cutting angle of the cutting tool are precisely controlled to ensure that the material does not produce burrs or breakage during cutting, while maintaining the flatness of the material to ensure the smooth progress of subsequent processing. After the cutting is completed, the strips of padding foam in the first combined material strip are neatly shaped.

[0058] Understandably, referring to Figure 1 , 3 As shown, step S130 also includes but is not limited to step S310 and step S320:

[0059] Step S310: providing a winding core;

[0060] Step S320: using a winding core to roll up the first combined material strip in its entirety to obtain a first product, wherein the entirety of the strip is rolled up while the strip-shaped raised foam and the bottom support film are in a composite state.

[0061] In the steps S310 and S320 shown in the embodiment of the present application, the first product after the whole-page winding process is wider, which reduces the risk of bursting and material flipping, and reduces the frequency of abnormalities. First, a winding core is provided to prepare for the subsequent whole-page winding, and the first combined material strip is wound in the composite state of the strip-shaped padding foam and the bottom film using the winding core. This process ensures that the material is wound neatly and compactly, avoids wrinkles and unevenness, reduces material damage and waste, and also provides standardized and unified raw materials for subsequent separation processing.

[0062] In some embodiments, the padding foam stripping and laminating equipment is provided with a winding station. Before starting the full-page winding, a winding core suitable for the current production process needs to be provided. The size and material of the winding core need to be reasonably selected according to the length, width and characteristics of the composite material of the first combined material strip. Generally, the winding core is made of solid metal or high-strength plastic material to ensure that it will not deform due to changes in internal and external pressure during the winding process. At the same time, the diameter and length of the winding core should be compatible with the winding reel on the pressing and cutting equipment so that the entire winding process can be completed smoothly. During the winding process, in order to ensure the tight winding of the material, the winding station is equipped with an automatic tension control device to monitor and adjust the material tension on the winding core in real time. This can prevent the material from being too loose or too tight, and avoid winding problems caused by uneven tension. The control system will automatically adjust the winding speed according to the thickness, width and tension requirements of the material to ensure that the material is wound evenly and avoid curling or bubbles. In addition, the winding station is also equipped with an automatic detection system that can monitor the quality of the first combined material strip during the winding process in real time to ensure that each roll of product meets the standards. If defects are detected in the material, such as breaks, bubbles or uneven seams, the system will immediately stop winding and an alarm will prompt the operator to check and repair the problem, improving the quality of the final product.

[0063] Understandably, referring to Figure 1 , 4 As shown, step S140 also includes but is not limited to step S410 and step S420:

[0064] Step S410: Separating the first product to obtain strip-shaped padding foam and a third combined material strip, wherein the strip-shaped padding foam is separated from the first product at intervals, and the third combined material strip includes a bottom film and the remaining strip-shaped padding foam;

[0065] Step S420: rolling up the third combined material strip to obtain a third product.

[0066] In step S410 and step S420 shown in the embodiment of the present application, first, the first product is separated, and the strip-shaped padding foam spacer is separated from the first product to form the strip-shaped padding foam and the third combined material strip, wherein the third combined material strip includes a bottom film and the remaining strip-shaped padding foam. The strip-shaped padding foam spacer is separated from the first product as needed, and the remaining strip-shaped padding foam can be used later, saving materials. Then, the third combined material strip is rolled up to obtain the third product, which provides a convenient product form for subsequent use and also reduces unnecessary material loss.

[0067] In some embodiments, the padding foam stripping and compounding equipment is provided with a separation station. First, the first product is sent to the separation station. The first product is a composite material after the whole page is rolled up, in which the strip-shaped padding foam and the bottom film are tightly combined. At this time, the separation station is equipped with a precise separation device, which can effectively separate the strip-shaped padding foam from the bottom film. The separation process adjusts the spacing and separation pressure so that the strip-shaped padding foam is separated from the first product one by one. Specifically, the equipment uses a robotic arm or an automated device to accurately separate the strip-shaped padding foam from the bottom film along the seam line of the composite material. During the separation process, the strip-shaped padding foam will maintain its integrity and ensure that it will not be broken or deformed.

[0068] Understandably, referring to Figure 1 , 4 As shown, after step S420, the following steps also include but are not limited to step S430, step S440, step S450 and step S460:

[0069] Step S430: Separate the third product to obtain strip-shaped padding foam and waste strips;

[0070] Step S440: providing a new release film and a new strip-shaped adhesive film; wherein the number of the new strip-shaped adhesive film and the strip-shaped padding foam matches;

[0071] Step S450: Compounding the new release film, the new strip-shaped adhesive film and the strip-shaped cushioning foam to obtain a second product; wherein the new strip-shaped adhesive film is located between the strip-shaped cushioning foam and the new release film;

[0072] Step S460: Discharge the waste tape.

[0073] In the steps S430, S440, S450 and S460 shown in the embodiment of the present application, first, the third product is separated and processed, and the strip-shaped padding foam is successfully separated from the waste belt, thereby ensuring the integrity of the strip-shaped padding foam and isolating the waste belt for subsequent processing. This step can make use of the third product and save materials. Next, a new release film and a new strip-shaped adhesive film are provided, and it is ensured that the number of the new strip-shaped adhesive film matches the number of the new strip-shaped padding foam, thereby avoiding material waste and improving the accuracy and efficiency of the composite process.

[0074] In some embodiments, the padding foam stripping and compounding equipment is provided with a recycling station. The recycling station can collect waste materials in an automated manner for subsequent waste treatment, which can effectively keep the production line clean and tidy, reduce the accumulation of invalid materials, and ensure the efficiency and environmental protection of the production environment.

[0075] Understandably, referring to Figure 1 , 5 As shown, step S160 also includes but is not limited to step S510, step S520 and step S530:

[0076] Step S510: Compounding the strip-shaped adhesive film and the strip-shaped padding foam to obtain a plurality of first compound material strips;

[0077] Step S520: performing a composite process on the release film and a plurality of first composite material strips to obtain a second composite material strip;

[0078] Step S530: rolling up the second composite material strip to obtain a second product.

[0079] Step S510, step S520 and step S530 shown in the embodiment of the present application optimize the combination of materials and the production of subsequent products through precise compounding and winding processing. First, the strip-shaped adhesive film and the strip-shaped padding foam are compounded to obtain a plurality of first composite material strips. This step ensures the close combination of the strip-shaped adhesive film and the strip-shaped padding foam, and provides a high-quality basic material for subsequent compounding. Then, the second composite material strip is obtained by compounding the release film and the plurality of first composite material strips. This compounding process tightly combines the release film with the composite material, ensures the firm bonding between the three layers of materials, and improves the overall performance and stability of the product.

[0080] In some embodiments, the strip-shaped adhesive film and the strip-shaped padding foam are firstly composited. The purpose of this process is to tightly combine the strip-shaped adhesive film and the strip-shaped padding foam to form a plurality of first composite material strips. During the composite process, the padding foam striping and composite equipment controls the pressure, temperature and time to make the bonding between the strip-shaped adhesive film and the padding foam more firm and uniform. The control system ensures that the spacing and bonding quality between each strip-shaped adhesive film and the strip-shaped padding foam are consistent, thereby ensuring the stability and reliability of the composite material strip.

[0081] It is understandable that the spacing between the first composite tapes on the second composite tape is equal. The equal spacing between the first composite tapes can enable the first composite tapes to evenly support the release film, reducing the risk of deformation of the release film due to uneven force.

[0082] It is understandable that the width of the padding foam raw material matches the width of the base film, reducing material waste.

[0083] It can be understood that the width of the strip-shaped padding foam matches the width of the strip-shaped adhesive film, thereby reducing the waste of material.

[0084] The embodiments of the present application have been described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
