Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing devices, in particular to a hot pressing device for processing water transfer paper. Background Art

[0002] A hot press is a device that heats two pre-tinned parts with flux to a temperature sufficient to melt and flow the solder. After solidification, a permanent electrical and mechanical connection is formed between the parts and the solder. The heating rate can be selected according to different products. The titanium alloy pressure head ensures uniform temperature, fast heating and long service life. As the pitch of PCB or FPC in consumer electronic products tends to be smaller, the traditional soldering process can no longer meet the requirements of extremely fine hot pressing. The ACF process has gradually been used by mobile phone designers. A Chinese patent discloses a hot pressing device for water transfer printing paper processing (authorization announcement number CN210101015U). This patented technology can dry the items after water transfer printing. If it is a solid object, it can be placed directly on the bottom plate inside the drying box, and then the two box doors are tightly closed with a handle. The power of the motor is turned on, the motor starts to work, and the motor shaft rotates at high speed, driving the three fan blades to rotate. The air is sucked into the air inlet on the rear side of the motor, and the power of the heating tube is turned on. The heating tube generates heat, and the motor generates wind to blow the heat generated by the heating tube to the isolation plate, and fill the entire drying box through the hot air holes inside the isolation plate to dry the solid objects. If it is an object such as cloth, the wet cloth that has completed water transfer printing is now placed on the bottom plate on the lower side of the pressing plate, and the pump power is turned on. The main pull rod and the auxiliary pull rod are lowered to press the wet cloth tightly, and the excess water in the cloth will be pressed out and flow out through the groove. Then the power of the motor is turned on to complete the same work as above, and the cloth is dried again, so that the cloth reaches a dry state without wrinkles. However, in the above structure, the hot air blown by the motor is blown to the entire drying box, and the hot air will float on the top side of the drying box due to its light weight. When the drying box is filled with hot air as a whole, the objects placed on the plate will be dried and hot-pressed, which reduces the drying efficiency and wastes energy. Therefore, a hot pressing device for water transfer paper processing is provided to solve the problems raised in the above background technology. Summary of the invention

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] See also Figures 1 to 5A hot pressing device for processing water transfer paper comprises a drying box 2, a bottom plate 1 is fixedly connected to the bottom side of the drying box 2, a pressing device is arranged on the upper side of the bottom plate 1, a hot pressing plate 103 is arranged inside the drying box 2, a through groove is arranged inside the hot pressing plate 103, a placing plate 305 is arranged on the bottom side of the inner wall of the drying box 2, a partition 302 is fixedly connected to the inside of the drying box 2, an air guide cavity 301 is arranged between the partition 302 and the inner wall of the drying box 2, a plurality of heating metal rods 303 are installed inside the air guide cavity 301, an air guide port 304 is opened on the partition 302, the air guide port 304 is connected with the air guide cavity 301, a fan 3 is installed on the air guide cavity 301, and the drying box 2 is movably connected to a sealing door 201 through a damping shaft.

[0023] Among them, by starting the fan 3 and the heating metal rod 303, the heating metal rod 303 will fill the interior of the air guide cavity 301 with hot air when working, and the fan 3 will blow the hot air through the air guide port 304 to the placement plate 305 when rotating. This method allows the watermarked paper to be directly dried by hot air, thereby improving the efficiency of drying and hot pressing. A through groove is provided on the hot pressing plate 103 to facilitate the circulation of hot air inside the hot pressing plate 103, so that the hot pressing plate 103 also has heat, thereby accelerating the hot pressing of the watermarked paper.

[0024] Preferably, the pressing device includes a gantry 101 , on which a cylinder 102 is mounted, and an output end of the cylinder 102 passes through the drying box 2 and is fixedly connected to the hot pressing plate 103 .

[0025] The cylinder 102 controls the up and down movement of the heat pressing plate 103, so as to heat-press the watermark paper.

[0026] Preferably, water guide grooves 306 are provided on both sides of the placement plate 305 , and the water guide grooves 306 are opened on the bottom wall of the drying box 2 . The drying box 2 is provided with a plurality of drainage holes 307 , and the drainage holes 307 are connected to the water guide grooves 306 .

[0027] The liquid (water generated during drying) generated on the placement plate 305 will be discharged into the drainage hole 307 through the water guide groove 306 , thereby accelerating the hot pressing process of the objects on the placement plate 305 .

[0028] Preferably, a plurality of exhaust slots 308 are provided on the side wall of the drying box 2 , and blades 309 are hingedly provided inside the exhaust slots 308 .

[0029] Among them, when the internal pressure of the drying box 2 is too high, the air pressure will push the hinged end of the blade 309 to deflect at an angle, so that the other end of the blade 3 will float out from the exhaust slot 308, so that the blade 309 as a whole will no longer block the exhaust slot 308, and the air inside the drying box 2 can be discharged through the exhaust slot 308. When the pressure of the drying box 2 is normal, the blade 309 will return to its initial position, that is, the blade 309 will be located inside the exhaust slot 308, blocking the exhaust slot 308, and preventing the air from flowing out through the exhaust slot 308, which can play a role in dust prevention and heat preservation for the drying box 2.

[0030] Preferably, a plurality of plug-in slots 202 are provided inside the sealing door 201 , and an electromagnet 203 is installed inside the plug-in slot 202 . A mounting slot 208 is provided inside the drying box 2 , and a plug-in block 210 is fixedly connected inside the mounting slot 208 via a spring 209 .

[0031] When the electromagnet 203 is started, the electromagnet 203 generates suction force, and then can absorb the plug-in block 210 inside the installation groove 208 through magnetic force, so that the plug-in block 210 is plugged into the inside of the plug-in groove 202, thereby preventing the sealing door 201 from opening by mistake.

[0032] Preferably, a heat-conducting cavity 204 is provided inside the sealed door 201 , a bimetallic strip 205 is installed inside the heat-conducting cavity 204 , a push switch 207 is provided on one side of the bimetallic strip 205 , and the push switch 207 is electrically connected to the electromagnet 203 .

[0033] Among them, when the sealed door 201 is subjected to high temperature, the heat conduction plate inside the sealed door 201 will transfer heat to the bimetallic strip 205, wherein the bimetallic strip 205 is U-shaped, causing the bimetallic strip 205 to deform due to the high temperature, so that one end of the bimetallic strip 205 is connected to the push switch 207, so that the push switch 207 opens the electromagnet 203, and the plug-in block 210 is plugged into the plug-in slot 202, closing the sealed door 201. When the temperature of the sealed door 201 drops, the bimetallic strip 205 returns to its initial position, thereby making the bimetallic strip 205 away from the push switch 207. The push switch 207 is a reset switch. After the push switch 207 is reset, the electromagnet 203 will lose power, and the plug-in block 210 will be reset under the action of the spring 209, so that the sealed door 201 can be opened. This structure can prevent the staff from being scalded when the sealed door 201 is opened due to excessive temperature, thereby protecting the safety of the staff.

[0034] Working principle: When in use, place the watermarked paper that needs to be hot-pressed on the placement plate 305 with a wet cloth on it, then close the sealing door 201, start the cylinder 102 to press the hot pressing plate 103 against the watermarked paper, and then start the fan 3 and the heating metal rod 303. When the heating metal rod 303 works, the inside of the air guide cavity 301 will be filled with hot air, and when the fan 3 rotates, the hot air will be blown onto the placement plate 305 through the air guide port 304. This method allows the watermarked paper to be directly dried by hot air, thereby improving the efficiency of drying and hot pressing. A through groove is provided on the hot pressing plate 103 to facilitate the circulation of hot air inside the hot pressing plate 103, so that the hot pressing plate 103 also has heat, which is convenient for accelerating the hot pressing of the watermarked paper.
