Description

Technical Field

[0001] The utility model provides a hot pressing device for preparing a reflective static sticker, which relates to the technical field of reflective static stickers. Background Technique

[0002] A reflective static sticker is a special sticker that combines reflective and static adsorption functions. It uses a PVC static film as the base material, can be adsorbed on a smooth surface without glue, is convenient to install and leaves no residual glue. The reflective property enables it to reflect light at night or in low light conditions, improving visibility, and is widely used in traffic safety signs, personal protective equipment, and advertising and promotion fields. This kind of sticker is not only environmentally friendly and durable, but also has good waterproof and temperature resistance performance, and is suitable for various environments.

[0003] The hot pressing process of a reflective static sticker is a technology that fixes the reflective material on the target surface by heating and pressing. When hot pressing the reflective static sticker, it is necessary to fix the reflective static sticker on the device, and then use a hot press or an iron to heat and press the material. Through hot pressing, the reflective static sticker can better adhere to the surface to be pasted, improving the adhesion strength and durability. However, when hot pressing the existing reflective static sticker, since wrinkles may occur when placing the reflective static sticker, it is necessary to manually smooth the reflective static sticker to avoid pressing out creases during hot pressing. However, the manual smoothing method is inefficient and the smoothing effect is not good.

[0004] Therefore, it is necessary to provide a hot pressing device for preparing a reflective static sticker that can smooth the reflective static sticker. Content of the Utility Model

[0005] In order to overcome the disadvantages that wrinkles may occur when placing the reflective static sticker and it is necessary to manually smooth the reflective static sticker, which is inefficient and has a poor smoothing effect, the utility model provides a hot pressing device for preparing a reflective static sticker that can smooth the reflective static sticker.

[0006] To achieve the above purpose, the embodiment of the utility model provides the following technical solution: A hot pressing device for preparing a reflective static sticker, including a base, a placement plate, a support frame, a cylinder, and a hot pressing plate. The placement plate is installed on the base, the support frame is installed at the rear of the base, the cylinder is installed on the support frame, the push rod of the cylinder is fixedly connected with the hot pressing plate, and the hot pressing plate is located directly above the placement plate. It also includes an installation block, a guide rod, a first electric slide rail, an elastic member, a first slider, and a pressing roller. Installation blocks are installed on both the front and rear sides of the upper part of the base. Guide rods are fixedly connected to both sides of the two installation blocks. A first electric slide rail is slidably arranged on the two guide rods of the same installation block. Elastic members are wound around each guide rod. Two first sliders are slidably arranged on the two first electric slide rails. A pressing roller is rotatably arranged on the two opposite first sliders.

[0007] Further, it further includes a mounting seat installed on the base. A vacuum pump is installed on the mounting seat. A gas guide pipe is commonly connected and communicated between the vacuum pump and the placement plate. A number of adsorption holes are formed on the placement plate.

[0008] Further, it further includes a second electric slide rail installed on the first electric slide rail. Second sliders are slidably arranged in both of the two second electric slide rails. An installation shell is commonly installed on the two second sliders. A plurality of fans are installed at the bottom of the installation shell. A condensing pipe is fixedly connected inside the installation shell. Dust-proof nets are installed at the air inlets of the installation shell.

[0009] Further, buffer pads are installed on both of the two mounting blocks.

[0010] Further, a lifting rod is fixedly connected between the two first electric slide rails.

[0011] Further, an air inlet pipe is connected and communicated with the placement plate. A pressure safety valve is arranged on the air inlet pipe.

[0012] Compared with the prior art, the hot pressing device provided by the embodiment of the present invention has the following advantages: 1. By placing the reflective static sticker on the placement plate and lifting the first electric slide rail upward along the guiding rod, the first sliders on both sides drive the pressing rollers to slide towards each other, and then the elastic member is used to push the first electric slide rail to reset. Subsequently, the first electric slide rail is started, so that the first sliders on both sides move away from each other. While the pressing rollers rotate on the first sliders, the reflective static sticker is smoothed, achieving the effect of smoothing the reflective static sticker.

[0013] 2. By starting the vacuum pump, the vacuum pump extracts the air inside the placement plate through the gas guide pipe, so that a negative pressure is formed inside the placement plate. The suction force generated by the negative pressure firmly fixes the reflective static sticker on the placement plate, achieving the effect of preventing the reflective static sticker from shifting during the hot pressing process.

[0014] 3. By starting the second electric slide rail, the second slider drives the installation shell to move. At the same time, the fan and the condensing pipe are started. The fan inhales the external air into the installation shell and cools the air through the condensing pipe. The cooled air is blown towards the reflective static sticker by the fan, achieving the effect of quickly cooling the reflective static sticker. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0020] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0021] Embodiment 1: A hot pressing device for preparing a reflective static sticker, refer to Figures 1-3 As shown, it includes a base 1, a placement plate 2, a support frame 3, a cylinder 4 and a hot pressing plate 5. The placement plate 2 is embedded and installed at the top of the base 1. The support frame 3 is installed at the rear side of the base 1 by means of bolt connection. The cylinder 4 is installed on the support frame 3 by means of bolt connection. The push rod of the cylinder 4 faces downward. The bottom of the push rod of the cylinder 4 is fixedly connected by means of bolt connection to the hot pressing plate 5. The hot pressing plate 5 is located directly above the placement plate 2. It also includes a mounting block 6, a guide rod 7, a first electric slide rail 8, an elastic member 9, a first slider 10 and a pressing roller 11. Mounting blocks 6 are installed on both the front and rear sides of the upper part of the base 1 by means of bolt connection. Guide rods 7 are fixedly connected to the left and right sides of the two mounting blocks 6 by means of welding. A first electric slide rail 8 is slidably arranged on the two guide rods 7 on the same mounting block 6. The first electric slide rail 8 slides up and down along the guide rod 7. Elastic members 9 for making the first electric slide rail 8 slide downward and reset are wound around each guide rod 7. Two first sliders 10 are slidably arranged horizontally on the two first electric slide rails 8. A pressing roller 11 for smoothing the reflective static sticker is rotatably arranged on the two opposite first sliders 10.

[0022] When hot pressing the reflective static sticker is required, first place the reflective static sticker on the placement plate 2. Subsequently, lift the first electric slide rails 8 on both sides upward along the guide rods 7. At this time, the elastic members 9 are stressed and compressed and deformed. Then start the first electric slide rails 8, so that the first sliders 10 on both sides drive the pressing rollers 11 to slide towards each other to the middle of the placement plate 2. Then release the first electric slide rails 8. At this time, the elastic members 9 push the first electric slide rails 8 to slide downward and reset, and the pressing rollers 11 press the reflective static sticker tightly on the placement plate 2. Subsequently, start the first electric slide rails 8 again, so that the first sliders 10 on both sides move away from each other. The first sliders 10 drive the pressing rollers 11 to move. While the pressing rollers 11 rotate on the first sliders 10, they smooth the reflective static sticker. Finally, by starting the cylinder 4, the push rod of the cylinder 4 pushes the hot pressing plate 5 downward, so that the hot pressing plate 5 presses on the reflective static sticker. By heating the hot pressing plate 5, the hot pressing process of the reflective static sticker is completed.

[0023] Embodiment 2: On the basis of Embodiment 1, refer to Figure 4 As shown, it further includes a mounting seat 12 installed on the base 1 by means of bolt connection. A vacuum pump 13 is installed on the mounting seat 12 by means of bolt connection. A gas guide pipe 14 is jointly connected and communicated between the vacuum pump 13 and the placement plate 2. A number of adsorption holes 201 are evenly opened on the placement plate 2.

[0024] After the reflective static sticker is placed on the placement plate 2, in order to prevent the reflective static sticker from shifting, by starting the vacuum pump 13, the vacuum pump 13 pumps out the air inside the placement plate 2 through the gas guide pipe 14. At this time, since the reflective static sticker covers the adsorption holes 201 on the placement plate 2, a negative pressure is formed inside the placement plate 2. The suction force generated by the negative pressure firmly fixes the reflective static sticker on the placement plate 2. When the vacuum pump 13 is turned off, the outside air re-enters the inside of the placement plate 2. At this time, the negative pressure suction force disappears, and the reflective static sticker can be easily removed.

[0025] Refer to Figure 5 As shown, it further includes a second electric slide rail 15 installed on the top of the first electric slide rail 8 by means of bolt connection. A second slider 16 is horizontally slidably arranged in each of the two second electric slide rails 15. A mounting shell 17 is jointly installed on the two second sliders 16 by means of bolt connection. Five blowers 18 blowing downward are installed at the bottom of the mounting shell 17 by means of bolt connection. A condensation pipe 19 is fixedly connected inside the mounting shell 17. Dust-proof nets 20 are embedded at the air inlets of the mounting shell 17 to prevent dust from entering the mounting shell 17 and blowing onto the reflective static sticker, so as not to affect the adhesiveness of the reflective static sticker.

[0026] After the hot pressing process of the reflective static sticker is completed, by activating the second electric slide rail 15, the second slider 16 drives the mounting shell 17 to slide on the second electric slide rail 15. At the same time, the fan 18 and the condensing pipe 19 are activated. The fan 18 sucks external air into the mounting shell 17 and cools the air through the condensing pipe 19. Then, the cooled air is blown by the fan 18 towards the hot-pressed reflective static sticker, enabling the reflective static sticker to cool rapidly without waiting for natural cooling. This can avoid the situation of poor adhesion caused by lifting it too quickly.

[0027] Refer to Figure 3 and Figure 4 As shown, buffer pads 21 are mounted on both of the two mounting blocks 6 by bonding; on the sides of the two first electric slide rails 8, a lifting rod 22 is fixedly connected together by means of bolt connection, and the number of the lifting rods 22 is two; on the side of the placing plate 2, an air inlet pipe 23 is connected and communicated, and a pressure safety valve 24 is arranged on the air inlet pipe 23.

[0028] When the elastic member 9 pushes the first electric slide rail 8 to slide downward and reset, the buffer pad 21 can prevent the first electric slide rail 8 from directly hitting the mounting block 6 and avoid damage to the first electric slide rail 8; when it is necessary to lift the two first electric slide rails 8 simultaneously, the lifting rod 22 can be directly lifted, which makes the operation more convenient and fast; when the vacuum pump 13 extracts the air in the placing plate 2, in order to avoid the reflective static sticker being torn by the suction force due to excessive negative pressure in the placing plate 2, when a certain negative pressure value is reached in the placing plate 2, the pressure safety valve 24 will automatically open to allow external air to enter the placing plate 2 through the air inlet pipe 23, thereby reducing the negative pressure value in the placing plate 2.

[0029] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
