Description

Technical Field

[0001] The invention belongs to the technical field of attaching equipment, in particular to a hot melt adhesive reflective film attaching equipment. Background Art

[0002] With the development of social economy and technology, "reflective materials" originally invented for road traffic safety have gradually entered the field of civilian safety protection. The application of reflective materials in clothing can not only improve the beauty and fashion of clothing, but also enhance the functionality of clothing. It can also serve as a warning in an emergency and improve the safety factor.

[0003] Reflective material, also known as retro-reflective material or retro-reflective material. Its reflective principle is to attach high-refractive glass beads or prism micro-lattices to the surface of the reflective material. When light hits the surface of the material, most of the light can be concentrated in a very small angle range and reflected back to the light source, forming a retro-reflective phenomenon. Therefore, it can effectively improve its own visibility, making it easy for people in the light source to find the target, effectively avoid accidents, and ensure personal safety. Reflective materials mainly include reflective film, reflective cloth, reflective leather, reflective webbing and reflective safety silk fabric.

[0004] Among them, hot melt adhesive is widely used in reflective film. A layer of glass beads is attached to the surface of the hot melt adhesive as a reflective surface layer. The reflective surface layer contains a layer of release paper to protect the reflective surface, which can be torn off during the processing. The hot melt adhesive film layer contains a layer of plastic film for protection.

[0005] However, when attaching the hot melt adhesive reflective film, a flat-plate heat press is used for bonding. When the heat press is working, the entire heat pressing working surface acts on the hot melt adhesive reflective film, making it difficult for the air between the hot melt adhesive reflective film and the substrate to be discharged. Bubbles are easily generated after attachment, resulting in reduced adhesion between the hot melt adhesive reflective film and the substrate, affecting the attachment quality.

[0006] In view of this, the present invention proposes a hot melt adhesive reflective film attaching device to solve the above technical problems. Summary of the invention

[0023] 1. The hot melt adhesive reflective film attaching device described in the present invention provides a hot pressing plate and a pressing block. The pressing block fixes one end of the hot melt adhesive reflective film and a substrate on the hot pressing table. The hot pressing plate moves from the fixed end of the hot melt adhesive reflective film and the substrate to the other end to discharge the air between the hot melt adhesive reflective film and the substrate, making it difficult to generate bubbles between the hot melt adhesive reflective film and the substrate, improving the adhesion between the hot melt adhesive reflective film and the substrate, thereby improving the attachment effect of the hot melt adhesive reflective film and the substrate, and further improving the attachment quality.

[0024] 2. The hot melt adhesive reflective film attaching device described in the present invention, by setting a pressure strip, a section of the hot melt adhesive reflective film from which the air has been discharged and both sides of the substrate are pressed tightly, and air is not easily entered from the side, thereby ensuring the effect of exhausting air and further ensuring the attachment effect.

[0026] 4. The hot melt adhesive reflective film attaching device described in the present invention is a device that winds the plastic film around the winding roller by setting a winding roller. When the hot pressing plate is pressing downward, the sliding bar extends outward. At this time, the pawl drives the ratchet wheel to rotate the winding roller, and the peeled plastic film is rolled onto the winding roller, which is convenient for recycling the plastic film, reduces manual recycling of the plastic film, and reduces labor intensity. After the attachment is completed, the hot pressing plate moves up and the sliding bar is reset. At this time, the pawl rotates on the sliding bar and no longer drives the ratchet wheel, so that when the sliding bar slides back and forth on the hot pressing table, the ratchet wheel rotates circumferentially, thereby recycling the plastic film.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 4 As shown, a hot melt adhesive reflective film attaching device according to the present invention comprises:

[0035] A hot press platform 1, wherein horizontal slide grooves 11 and vertical slide grooves 12 are provided on both sides of the hot press platform 1, and an electric push rod 13 is fixedly connected to the bottom of the top plate of the hot press platform 1;

[0036] A hot pressing plate 2, one end of which is slidably connected to the horizontal slide groove 11, and the other end of which is transmission-connected to the electric push rod 13 via a connecting rod;

[0037] A pressing block 3, wherein the pressing block 3 is slidably connected to the vertical slide groove 12, and the pressing block 3 is also transmission-connected to one end of the hot pressing plate 2 close to the electric push rod 13 through a connecting rod;

[0038] A controller, the controller is used to control the operation of the hot melt adhesive reflective film attaching device;

[0039] In the prior art, a flat-plate heat press is used to attach the hot-melt adhesive reflective film. When the hot-pressing machine is working, the entire heat-pressing working surface acts on the hot-melt adhesive reflective film, making it difficult for the air between the hot-melt adhesive reflective film and the substrate to be discharged. Bubbles are easily generated after attachment, which reduces the adhesion between the hot-melt adhesive reflective film and the substrate, affecting the attachment quality.

[0040] In the present invention, by setting the hot press plate 2 and the pressing block 3, when attaching the hot melt adhesive reflective film to the substrate, the substrate is first placed on the hot press table 1, then the plastic film of the hot melt adhesive reflective film is peeled off, and then the hot melt adhesive reflective film is covered on the substrate, and the electric push rod 13 is controlled by the controller to extend, and the hot press plate 2 is driven to slide in the horizontal slide groove 11 on the hot press table 1 through the connecting rod between the electric push rod 13 and the hot press plate 2, and at the same time, the hot press plate 2 and the pressing block 3 are connected. The connecting rod drives the pressing block 3 to slide in the vertical slide groove 12, and the pressing block 3 moves downward to press the ends of the hot melt adhesive reflective film and the substrate on the hot pressing platform 1. The hot pressing plate 2 makes the hot melt adhesive reflective film and the substrate fit tightly on the hot pressing platform 1 at the end away from the electric push rod 13. When the hot pressing plate 2 slides in the horizontal slide groove 11, the air between the hot melt adhesive reflective film and the substrate is discharged. When the hot pressing plate 2 is in a horizontal state, the hot pressing plate 2 presses the hot melt adhesive reflective film and the substrate on the hot pressing platform 1. The hot pressing plate 2 and the hot pressing platform 1 are heated to melt the hot melt adhesive, so that the hot melt adhesive reflective film is attached to the substrate. After maintaining the pressure for a certain period of time, the attachment is completed, and the controller controls the electric push rod 13 to retract and reset. At this time, the hot pressing plate 2 is lifted while sliding in the horizontal slide groove 11, and the pressing block 3 slides upward in the vertical slide groove 12, thereby loosening the hot melt adhesive reflective film and the substrate, pulling the attached hot melt adhesive reflective film and the substrate, and then hot pressing and attaching the next section to be processed. In the present invention, by setting the hot pressing plate 2 and the pressing block, the pressing block 3 fixes one end of the hot melt adhesive reflective film and the substrate on the hot pressing platform 1, and the hot pressing plate 2 moves from the fixed end of the hot melt adhesive reflective film and the substrate to the other end, and the air between the hot melt adhesive reflective film and the substrate is discharged, so that it is not easy to generate bubbles between the hot melt adhesive reflective film and the substrate, thereby improving the adhesion between the hot melt adhesive reflective film and the substrate, thereby improving the attachment effect of the hot melt adhesive reflective film and the substrate, and then improving the attachment quality.

[0041] As an embodiment of the present invention, strips 4 are fixedly connected to both sides of the hot pressing plate 2, and an angle is set between the strips 4 and the hot pressing plate 2, and the strips 4 are elastic steel sheets; during operation, by setting the strips 4, when the hot pressing plate 2 discharges the air between the reflective film and the substrate, the angle between the hot pressing plate 2 and the hot pressing platform 1 gradually decreases. At this time, the strips 4 gradually contact the hot melt adhesive reflective film, thereby pressing the hot melt adhesive reflective film on the substrate, so that a section of the hot melt adhesive reflective film that has discharged air and both sides of the substrate are pressed, and it is not easy for air to enter from the side, thereby ensuring the air exhaust effect and then ensuring the attachment effect. The strips 4 of the elastic steel sheet keep the hot melt adhesive reflective film and both sides of the substrate pressed on the hot pressing platform 1 during hot pressing and attachment, further ensuring the hot pressing effect. After the attachment is completed, the elastic steel sheet rebounds, causing the hot pressing plate 2 to quickly tilt up, thereby separating the hot pressing plate 2 from the hot melt adhesive reflective film and the substrate, avoiding too long pressing time and ensuring the pressing quality.

[0043] As an embodiment of the present invention, the hot pressing platform 1 is provided with a pressing groove 15 which cooperates with the pressing strip 4; during operation, by setting the pressing groove 15, when the pressing strip 4 presses the hot melt adhesive reflective film and the substrate toward the hot pressing platform 1, the pressing strip 4 presses the hot melt adhesive reflective film and the substrate into the pressing groove 15. At this time, both sides of the hot melt adhesive reflective film and the substrate are pulled, which further presses the hot melt adhesive reflective film toward the substrate, discharges air, and ensures the adhesion effect. The hot melt adhesive reflective film and the substrate are bent at the pressing groove 15, which makes it more difficult for air to enter and bubbles to be generated, thereby ensuring the adhesion quality.

[0045] As an embodiment of the present invention, a spring 31 is provided in the vertical slide groove 12, the top end of the spring 31 is fixedly connected to the vertical slide groove 12, and the bottom end of the spring 31 is fixedly connected to the pressure block 3; during operation, by arranging the spring 31 in the vertical slide groove 12, when the controller controls the electric push rod 13 to extend, the angle between the hot pressing plate 2 and the hot pressing platform 1 is reduced, so that the connecting rod between the hot pressing plate 2 and the pressure block 3 is relaxed, thereby causing the spring 31 to reset and extend, and the pressure block 3 is quickly moved in the vertical slide groove 12 to press the hot pressing platform 1, thereby pressing the hot melt adhesive reflective film and the substrate on the hot pressing platform 1 for fixing, so that the hot melt adhesive reflective film and the substrate are fixed before the hot pressing plate 2 slides, so that the hot melt adhesive reflective film and the substrate are fixed at one end when the hot pressing plate 2 exhausts air, and it is not easy for the hot melt adhesive reflective film and the substrate to move with the hot pressing plate 2, thereby ensuring the effect of exhausting air of the hot pressing plate 2.

[0046] As an embodiment of the present invention, a heat-resistant buffer pad 32 is provided at the bottom of the pressing block 3, and an anti-slip texture is provided at the bottom of the heat-resistant buffer pad 32; during operation, by providing the heat-resistant buffer pad 32, when the pressing block 3 is pressed against the hot-melt adhesive reflective film and the substrate, the pressing block 3 is in flexible contact with the hot-melt adhesive reflective film and the substrate, effectively protecting the hot-melt adhesive reflective film and the substrate, avoiding damage to the hot-melt adhesive reflective film and the substrate when the pressing block 3 fixes the hot-melt adhesive reflective film and the substrate, and a protective texture is provided at the bottom of the heat-resistant buffer pad 32 to increase the roughness of the bottom of the pressing block 3, thereby increasing the friction between the pressing block 3 and the hot-melt adhesive reflective film and the substrate, improving the pressing effect, and thus ensuring the attachment quality.

[0047] As an embodiment of the present invention, slide bars 51 are slidably connected on both sides of the hot pressing platform 1, and the slide bars 51 are rotatably connected to the hot pressing plate 2, and release plates 52 are fixedly connected between the slide bars 51; during operation, by setting the release plates 52, when the hot pressing plate 2 slides in the horizontal slide groove 11 of the hot pressing platform 1, the hot pressing plate 2 drives the slide bars 51 to slide on both sides of the hot pressing platform 1, and during pressing, the slide bars 51 extend outward, so that the release plates 52 extend outward, the plastic film of the hot melt adhesive reflective film is on the lower side of the release plate 52, and the hot melt adhesive layer of the hot melt adhesive reflective film is on the upper layer of the release plate 52, and the release plate 52 peels off the plastic film from the hot melt adhesive reflective film during the process of extending outward, which is convenient for attachment, reduces manual film tearing, reduces labor intensity, and improves attachment efficiency.

[0048] As an embodiment of the present invention, a guide groove 53 is provided on the release plate 52; during operation, by setting the guide groove 53, the hot melt adhesive reflective film peeled off the plastic film is inserted into the guide groove 53, and when the hot melt adhesive reflective film slides in the guide groove 53, the hot melt adhesive reflective film is smoothed and guided, so that the hot melt adhesive reflective film is flattened before attachment, which is convenient for the hot pressing plate 2 to exhaust air and fit, thereby ensuring the attachment quality.

After the attachment is completed, the hot pressing plate 2 moves up, and the slide bar 51 is reset. At this time, the pawl 54 rotates on the slide bar 51 and no longer drives the ratchet 61, so that when the slide bar 51 slides back and forth on the hot pressing platform 1, the ratchet 61 rotates circumferentially, thereby recycling the plastic film.

[0050] The specific workflow is as follows:

[0051] During operation, by setting the hot press plate 2 and the pressing block 3, when attaching the hot melt adhesive reflective film to the substrate, the substrate is first placed on the hot press table 1, then the plastic film of the hot melt adhesive reflective film is peeled off, and then the hot melt adhesive reflective film is covered on the substrate, and the electric push rod 13 is controlled to extend by the controller, and the hot press plate 2 is driven to slide in the horizontal slide groove 11 on the hot press table 1 through the connecting rod between the electric push rod 13 and the hot press plate 2, and the pressing block 3 is driven to slide in the vertical slide groove 12 through the connecting rod between the hot press plate 2 and the pressing block 3, and the pressing block 3 moves downward to press the ends of the hot melt adhesive reflective film and the substrate on the hot press table 1, and the hot press plate 2 At the end away from the electric push rod 13, the hot melt adhesive reflective film and the substrate are tightly attached to the hot pressing table 1. When the hot pressing plate 2 slides in the horizontal slide groove 11, the air between the hot melt adhesive reflective film and the substrate is discharged. When the hot pressing plate 2 is in a horizontal state, the hot pressing plate 2 presses the hot melt adhesive reflective film and the substrate on the hot pressing table 1.

By setting the pressure strip 4, when the hot pressing plate 2 discharges the air between the reflective film and the substrate, the angle between the hot pressing plate 2 and the hot pressing platform 1 gradually decreases. At this time, the pressure strip 4 gradually contacts the hot melt adhesive reflective film, thereby pressing the hot melt adhesive reflective film on the substrate, so that the hot melt adhesive reflective film and the two sides of the substrate that have been discharged from the air are pressed, and it is not easy for air to enter from the side, thereby ensuring the air exhaust effect and then ensuring the attachment effect.
