Description

Technical Field

[0001] The invention relates to the technical field of preparation and collection of reflective beaded films, and in particular to a collection device for preparing reflective films. Background Art

[0002] Reflective film is a kind of retro-reflective material that can be directly used after being made into a thin film. It is made through glass bead technology, microprism technology, synthetic resin technology, thin film technology, coating technology and micro-replication technology. It is widely used as a sign in various aspects of life, such as road signs, truck body identification, clothing with warning functions, etc.

[0003] Among them, the reflective film made by glass microbead technology is called reflective beaded film, which is composed of a reflective layer, a resin layer, a substrate film layer and glass microbeads. During the preparation process, the reflective layer and the substrate film layer are compounded by hot pressing film equipment, and then the outer beaded layer is formed by planting glass microbeads in the resin layer. However, the beaded layer of the reflective beaded film will reduce its ductility after adding glass microbeads. When the existing reflective film winding equipment directly winds and collects the reflective beaded film and the release film until completion, the resin of the outer beaded layer of the reflective beaded film will cool down and shrink, which increases the winding tension between the layers, causing the outer beaded layer and the release film to shrink and deform laterally at the bonding site, resulting in the beading layer falling off or even breaking.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1-Figure 6 A collecting device for preparing reflective film comprises a collecting table 1 for winding and collecting reflective beaded film, a multi-layer unwinding assembly 11 is arranged on the top of the collecting table 1, and the multi-layer unwinding assembly 11 is composed of a protective film unwinding roller and a release film unwinding roller, a laminating hot pressing unit is arranged on the top of the collecting table 1, and the laminating hot pressing unit is composed of a protective glue coating mechanism and a laminating hot pressing mechanism, the protective glue coating mechanism is used to coat a glue layer on the surface of the reflective beaded film, the laminating hot pressing mechanism is used to hot-press the protective film and the release film to the surface of the reflective beaded film, and a multi-layer winding adjustment mechanism is arranged on the right side of the laminating hot pressing mechanism, and the multi-layer winding adjustment mechanism is used to adjust the tension between the layers of reflective beaded film after laminating.

[0034] Through the above technical scheme, when the reflective bead-embedded film is wound, the reflective bead-embedded film is pulled by the existing pulling equipment, and the protective film and the release film are released by the multi-layer unwinding component 11 to adhere the matching colloid layer to the outer surface of the reflective bead-embedded film, and then it is hot-pressed and laminated by a laminating and hot-pressing mechanism to form a reflective bead-embedded composite film, and then the winding tension of each layer of the reflective bead-embedded composite film during the winding process is adjusted by the multi-layer winding adjustment mechanism, and the winding tension of each layer after the winding is completed and cooled is buffered and adjusted.

[0035] like Figure 1 and Figure 2 As shown, the protective glue coating mechanism includes a double-sided coating bracket 2 arranged on the top of the collecting platform 1, and the double-sided coating bracket 2 is connected to the protective film glue layer coating tube 22 and the release film glue layer coating tube 23 through an adhesive glue tube 21, and the inner walls of the protective film glue layer coating tube 22 and the release film glue layer coating tube 23 are rotatably connected to a coating roller 24, and a liquid storage tank is provided on the outer surface of the coating roller 24.

[0036] Through the above technical scheme, the protective film gelatinous layer coating tube 22 and the release film gelatinous layer coating tube 23 are respectively located on the upper and lower sides of the reflective beaded film, a liquid storage groove is opened on the outer surface of the coating roller 24, and the reflective beaded film forms an "S" shaped curved surface through the protective film gelatinous layer coating tube 22 and the release film gelatinous layer coating tube 23, thereby increasing the contact area between the coating roller 24 and the coating surface.

[0037] Based on the above, when the reflective beaded film is driven by the existing traction equipment to pass through the double-sided coating bracket 2, the protective film gelatin layer coating tube 22 contacts the top of the reflective beaded film, and the release film gelatin layer coating tube 23 contacts the bottom of the reflective beaded film, thereby bending the reflective beaded film into an S shape, and then the adhesive glue is injected into the protective film gelatin layer coating tube 22 and the release film gelatin layer coating tube 23 through the adhesive glue tube 21, and coated on the upper and lower sides of the reflective beaded film, thereby completing the coating operation of the gelatin layers on the upper and lower sides of the reflective beaded film.

[0038] like Figure 2 As shown, the laminating hot pressing mechanism consists of a protective layer hot pressing component and a uniform laminating component. The protective layer hot pressing component includes a hot pressing platform 3 arranged on the right side of the double-sided coating bracket 2. An electric lifting hydraulic cylinder 31 is arranged on the top of the hot pressing platform 3. The bottom of the electric lifting hydraulic cylinder 31 is connected to a hot pressing adjustment seat 32 through a hydraulic connecting rod. The inner wall of the hot pressing adjustment seat 32 is rotatably connected to a hot pressing adjustment roller 33, and a resistance heating component is arranged in the hot pressing adjustment seat 32.

[0039] Through the above technical solution, the heat pressing adjustment rollers 33 are arranged opposite to each other, and the heights of the opposite sides of the two heat pressing adjustment rollers 33 are adjusted by the electric hydraulic cylinder 331. The protective film, reflective bead film and release film are arranged from high to low and are bonded in the heat pressing adjustment seat 32.

[0040] Based on the above, after the colloid layer on the upper and lower sides of the reflective bead-embedded film is coated, the protective film and the release film are released outward through the multi-layer unwinding component 11, and are respectively bonded to the top and bottom of the reflective bead-embedded film, and then when passing through the hot pressing adjustment seat 32, the protective film, the reflective bead-embedded film and the release film are hot-pressed and bonded by the hot pressing adjustment roller 33, and the bonding gap is filled by the colloid layer in the bonding gap, so that the protective film, the reflective bead-embedded film and the release film are hot-pressed and bonded into a reflective bead-embedded composite film.

[0041] Based on the above, further Figure 2 and Figure 3 As shown, the uniform fitting component includes a colloid uniform support 4 arranged on the right side of the hot pressing table 3, and two groups of symmetrically arranged driving oblique slides 41 are fixed to the inner wall of the colloid uniform support 4, and a cleaning conical groove 42 is opened on the left side of the driving oblique slide 41, and the driving oblique slide 41 is composed of a forward driving slide 411 and a reverse driving slide 412, and a driving arc slider 413 is fixed on the opposite side of the forward driving slide 411 and the reverse driving slide 412, so that when the reflective implanted bead composite film passes between the driving arc sliders 413, the excess colloid layer in the reflective implanted bead composite film is slid and removed through the cleaning conical groove 42, so as to avoid the colloid layers sticking to each other during winding, thereby reducing the quality of the reflective implanted bead composite film.

[0042] Through the above technical scheme, after the protective film and the release film are bonded to the surface of the reflective bead-embedded film, they are passed through the colloid uniform bracket 4, and the colloid layer at the bonding position is driven to move by the inclined driving inclined slide 41, so that in the process of driving the colloid layer front and back in sequence, the thickness of the colloid layer at the bonding position is made to be the distance between the two driving arc-shaped slide blocks 413, so that the colloid layer is coated more evenly, and in the driving process, the excess glass beads in the bead-embedded layer with stacked beads and floating beads during the hot pressing process can be moved to the glass bead planting interval or removed from the front and back sides of the colloid layer, so as to achieve the effect of improving the quality of the reflective bead-embedded film.

[0043] like Figure 2 and Figure 4 As shown, the multi-layer winding adjustment mechanism is composed of a winding drive component and a winding adjustment component. The winding drive component includes a winding bracket 5 arranged on the right side of the colloid uniform bracket 4. A winding servo motor 51 is arranged on the back of the winding bracket 5, and the winding servo motor 51 is fixed with a winding roller shaft 52 through an output shaft. The inner wall of the winding bracket 5 is slidably provided with a fitting seat 53 through a compression assembly, and the fitting seat 53 is fitted with the winding roller shaft 52 through a fitting slide column 531.

[0044] Through the above technical solution, during the rotation of the tension adjusting sleeve 6, the fitting slide column 531 is always fitted with the surface of the tension adjusting sleeve 6, so that the reflective bead-embedded composite film can always fit with the outer surface of the tension adjusting sleeve 6 during the winding process, avoiding the generation of bubbles that affect the winding tension between the layers of the film.

[0045] like Figure 4-Figure 6 As shown, the winding adjustment component includes a tension adjustment sleeve 6 which is sleeved on the outer surface of the winding roller shaft 52, and the outer side of the tension adjustment sleeve 6 is slidably connected to a tension initial adjustment slide 61 through an elastic component, and the tension adjustment sleeve 6 is fixed with an internal tension adjustment fixed slider 62 through a fixing bolt, and the opposite side of the internal tension adjustment fixed slider 62 is clamped with an internal tension adjustment dividing strip 63, so that when it is necessary to remove the internal tension adjustment dividing strip 63 or when unwinding the reflective bead film, the internal tension adjustment fixed slider 62 is removed from the tension adjustment sleeve 6 by rotating the fixing bolt, and the clamping constraint of the internal tension adjustment dividing strip 63 is released, so that the internal tension adjustment dividing strip 63 at the corresponding position can be removed from the tension adjustment sleeve 6, ensuring that the reflective bead film can be unwound and used normally.

[0046] Through the above technical solution, the internal tension adjustment partition strip 63 is hollowly arranged, the fitting seat 53 is connected to the internal tension driving slider 532 through a fixed connecting rod, and the internal tension driving slider 532 is touched and connected with the bottom of the internal tension adjustment partition strip 63, and the inner wall of the winding bracket 5 is provided with a partition storage arc groove 54 which is slidably connected with the internal tension adjustment partition strip 63.

[0047] Based on the above, after the internal colloid layer of the reflective bead-embedded composite film is homogenized by the colloid uniformity mechanism, the winding roller 52 is driven to rotate continuously by the winding servo motor 51, which drives the tension adjustment sleeve 6 sleeved on its surface to rotate, thereby driving the reflective bead-embedded composite film to adhere to the outer surface of the tension adjustment sleeve 6 for winding. During this period, the tension of each layer of the wound reflective bead-embedded composite film is preliminarily adjusted by the initial tension adjustment slide 61, that is, when the reflective bead-embedded composite film shrinks, the initial tension adjustment slide 61 is driven to shrink, and when the reflective bead-embedded composite film expands, the initial tension adjustment slide 61 is driven to expand outward, thereby reducing the winding tension between the layers of the reflective bead-embedded composite film after the winding is completed;

[0048] Based on the above, when the initial tension adjustment slide 61 rotates to the bottom of the fitting slide 531, the compression fitting slide 531 slides inward, so that the internal tension driving slider 532 drives the internal tension adjustment dividing strip 63 to rise to the inner wall of the internal tension adjustment fixed slider 62, separating the layer from the next layer of the reflective bead-embedded composite film, forming an inwardly concave tension adjustment curved surface, which can buffer and adjust the tension between the layers of the reflective bead-embedded composite film after winding.

[0049] Working principle:

[0050] When the reflective beaded film is wound and collected by the present invention, it will go through a gelatin layer coating process, a hot pressing bonding process and a winding adjustment process in sequence according to the travel trajectory of the reflective beaded film, wherein the gelatin layer coating process is specifically as follows: when the reflective beaded film passes through the existing traction equipment and is driven to pass through the double-sided coating bracket 2, the protective film gelatin layer coating tube 22 contacts the top of the reflective beaded film, and the release film gelatin layer coating tube 23 contacts the bottom of the reflective beaded film, thereby bending the reflective beaded film into an S shape, and then the adhesive glue is injected into the protective film gelatin layer coating tube 22 and the release film gelatin layer coating tube 23 through the adhesive glue tube 21, and coated on the upper and lower sides of the reflective beaded film, thereby completing the coating operation of the gelatin layers on the upper and lower sides of the reflective beaded film.

[0051] Based on the above, the hot pressing bonding process is specifically as follows: after the colloid layer on the upper and lower sides of the reflective bead-planting film is coated, the protective film and the release film are released outward through the multi-layer unwinding component 11, and are respectively bonded to the top and bottom of the reflective bead-planting film, and then when passing through the hot pressing adjustment seat 32, the protective film, the reflective bead-planting film and the release film are hot pressed and bonded through the hot pressing adjustment roller 33, and the bonding gap is filled by the colloid layer in the bonding gap, so that the protective film, the reflective bead-planting film and the release film are hot pressed and bonded into a reflective bead-planting composite film;

[0052] Based on the above, after the protective film and the release film are attached to the surface of the reflective bead-embedded film, they are passed through the colloid uniform support 4, and the colloid layer at the attached part is driven to move by the inclined driving inclined slide 41, so that in the process of driving the colloid layer front and back in sequence, the thickness of the colloid layer at the attached part is made to be the distance between the two driving arc-shaped slide blocks 413, so that the colloid layer is coated more evenly, and in the driving process, the excess glass beads in the bead-embedded layer with stacked beads and floating beads during the hot pressing process can be moved to the glass bead planting interval or removed from the front and back sides of the colloid layer, so as to achieve the effect of improving the quality of the reflective bead-embedded film;

[0053] Based on the above, when the reflective bead-embedded composite film passes between the driving arc sliders 413, the excess colloid layer in the reflective bead-embedded composite film is slid and removed by cleaning the conical groove 42 to avoid the colloid layers sticking to each other during winding, thereby reducing the quality of the reflective bead-embedded composite film.

[0054] Based on the above, the winding adjustment process is specifically as follows: after the reflective bead-embedded composite film has been homogenized by the colloid uniformity mechanism for the internal colloid layer, the winding servo motor 51 drives the winding roller 52 to rotate continuously, thereby driving the tension adjustment sleeve 6 sleeved on its surface to rotate, thereby driving the reflective bead-embedded composite film to adhere to the outer surface of the tension adjustment sleeve 6 for winding, during which the tension of each layer of the wound reflective bead-embedded composite film is preliminarily adjusted by the tension initial adjustment slide 61, that is, when the reflective bead-embedded composite film shrinks, the tension initial adjustment slide 61 is driven to shrink, and when the reflective bead-embedded composite film expands, the tension initial adjustment slide 61 is driven to expand outward, thereby reducing the winding tension between the layers of the reflective bead-embedded composite film after the winding is completed;

[0055] Further based on the above, during the rotation of the tension adjustment sleeve 6, the fitting slide 531 is always fitted with the surface of the tension adjustment sleeve 6, so that the reflective bead-embedded composite film can always fit the outer surface of the tension adjustment sleeve 6 during the winding process, avoiding the generation of bubbles that affect the winding tension between the layers of film. At the same time, when the initial tension adjustment slide 61 rotates to the bottom of the fitting slide 531, the fitting slide 531 is squeezed to slide inward, so that the internal tension driving slider 532 drives the internal tension adjustment dividing strip 63 to rise to the inner wall of the internal tension adjustment fixed slider 62, separating the layer from the next layer of the reflective bead-embedded composite film, forming an inwardly concave tension adjustment curved surface, which can buffer and adjust the tension between the layers of film after the reflective bead-embedded composite is wound;

[0056] Based on the above, after each layer of the reflective bead-embedded composite film is wound, when the winding tension increases, the internal tension adjustment dividing strip 63 is compressed to expand the winding area of ​​the layer and reduce its winding tension. Conversely, the distance between the internal tension adjustment dividing strips 63 is expanded to increase its winding tension. The winding tension of each layer of the reflective bead-embedded composite film is thereby controlled within an acceptable range, i.e., within the deformation amount of the hollow internal tension adjustment dividing strip 63, thereby completing the tension adjustment process of the reflective bead-embedded composite film.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
