Description

Technical Field

[0001] This utility model relates to the field of processing transfer technology, and in particular to a transfer machine for processing cabinet doors. Background Technology

[0002] Cabinet doors, including wardrobe doors, cupboard doors, and other cabinet doors, are often printed with different patterns during production and processing, such as wood grain patterns, to enhance their aesthetics. Cabinet door transfer printing often uses transfer machines to transfer patterns onto the surface of wooden, metal (such as steel), or composite material cabinet doors. Its core function is to permanently transfer the pattern from the decorative film to the substrate surface through physical or chemical methods.

[0003] Existing technologies for cabinet door transfer printing have certain shortcomings. For example, when using heat transfer printing, the pattern paper is laid flat on the surface of the cabinet door, and the pattern and the cabinet door are vacuum-sealed and heated. However, since the surface of the cabinet door has a raised or recessed pattern, a single vacuum cannot make the pattern paper adhere evenly to the surface of the cabinet door. Furthermore, after heating, it needs to be naturally dried before the next step can be carried out. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a transfer printing machine for cabinet door processing, which has the advantages of high vacuum sealing efficiency and rapid cooling, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a transfer printing machine for cabinet door processing, comprising a working box, the working box including a bottom box, a top box, and side plates, the top box being located above the bottom box, the bottom box and the top box having side plates fixedly connected to both sides, the top of the top box having a symmetrically arranged top plate, the top box having a heating box inside, the bottom wall of the top plate having a cylinder symmetrically fixedly connected, the output shaft of the cylinder being connected to the top of the heating box, the tail end of the cylinder having a connecting pipe inside the top plate, the working box having support plates symmetrically installed on both sides, the top of adjacent support plates having a bearing plate slidably installed, the top of the bearing plate having an upper closing plate movably connected, and the bottom opening of the top box having a spray pipe symmetrically fixedly installed.

[0006] With the above structural design, and by setting the cooperation between the support plate and the upper plate, the transfer paper evenly fills the grooves on the surface of the cabinet door due to the pressure of the pulley and the injection of the air pipe, thus achieving the effect of uniform coverage of the transfer paper.

[0007] Preferably, the working box has symmetrical slots on both sides, the support plate is engaged in the slots, the bottom end of the support plate is fixedly installed with a support leg, the top surface of the support plate is provided with a slide rail B, and the two inner walls of the side plate are provided with slide rails A.

[0008] The above structural design allows the support plate to slide linearly, limiting the sliding angle of the support plate and preventing positional displacement when the upper plate is pressed against the heating box.

[0009] Preferably, the bearing plate has an internal air pressure chamber, and an air bag is fixedly connected to the top wall of the air pressure chamber. The air bag is made of flexible material, and an air supply pipe is provided on one side of the bearing plate, which is connected to the inside of the air pressure chamber.

[0010] With the above structural setup, after the air extraction pipe extracts the air, compressed air is injected into the air delivery pipe, causing the air delivery pipe to expand under force and push the cabinet door upward, making the connection between the cabinet door and the transfer paper tighter.

[0011] Preferably, the inner wall of the support plate is inclined, the top of the support plate is provided with a sealing silicone strip, one side of the support plate is provided with an air extraction pipe at both ends, the air extraction pipe is connected to the interior of the support plate, and pulleys are symmetrically installed on both sides and the bottom of the support plate. The bottom pulley slides inside the slide rail B, and the side pulleys slide inside the slide rail A.

[0012] With the above structural design, when the plastic pad is pressed into the interior of the support plate, the angle between the plastic pad and the inner wall of the support plate is reduced, making the air content between the support plate and the upper plate smaller, so that the plastic pad can completely absorb the transfer paper onto the surface of the cabinet door.

[0013] Preferably, a sealing groove is formed on the bottom wall of the upper plate at the position corresponding to the sealing silicone strip, and a plastic pad is installed inside the upper plate, the plastic pad being made of a flexible transparent material.

[0014] Through the above structural design, the plastic pad adheres to the surface of the cabinet door, causing the transfer paper to adhere evenly. Subsequently, the plastic pad adheres more tightly to the inclined inner wall of the support plate, resulting in a lower air content between the support plate and the upper plate.

[0015] Preferably, the bottom of the nozzle is uniformly equipped with nozzles in a linear array, and the top of the nozzle is provided with a transmission pipe.

[0016] With the above-mentioned structure, compressed air is ejected from the nozzle. As the upper panel is pulled out, the nozzle ejects compressed air onto the surface of the upper panel, which quickly exchanges heat between the plastic pad and the cabinet door, causing the temperature of the cabinet door and the plastic pad to drop rapidly.

[0017] This utility model has the following advantages:

[0018] 1. This transfer printing machine for cabinet door processing achieves high vacuum bonding efficiency through the design of a support plate, upper plate, and air bladder. The cabinet door is placed above the air bladder, and then the transfer paper is placed on the surface of the cabinet door. The sealing groove of the upper plate is aligned with the sealing silicone strip and installed to form a seal between the support plate and the upper plate. At this time, the air extraction pipe is connected to the air pump, and the air between the support plate and the upper plate is sucked out through the air extraction pipe. While the plastic pad moves and bonds, it squeezes the transfer paper between the transfer paper and the cabinet door, pressing the transfer paper to adhere to the surface of the cabinet door. Then, the air supply pipe is connected to the air compressor, and compressed air is introduced into the air pressure chamber through the air supply pipe. The air bladder expands under pressure, pushing the cabinet door upward, making the connection between the cabinet door and the transfer paper even tighter, resulting in a high bonding efficiency.

[0019] 2. This transfer printing machine for cabinet door processing achieves rapid cooling by setting up a structure such as a spray pipe, nozzle, and transmission pipe. Compressed air is introduced into the interior of the spray pipe through the transmission pipe and sprayed out from the nozzle. When the support plate is pulled, the surface of the upper plate is uniformly cooled by the compressed air sprayed from the nozzle, which enables rapid heat exchange between the plastic pad and the cabinet door, causing the temperature of the cabinet door and the plastic pad to drop rapidly, shortening the cooling rate of the plastic pad and the cabinet door, and achieving a rapid cooling effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-2 A transfer printing machine for cabinet door processing includes a working box 1, which includes a bottom box 11, a top box 12, and side plates 13. The top box 12 is located above the bottom box 11. The side plates 13 are fixedly connected to both sides of the bottom box 11 and the top box 12. The top of the top box 12 is symmetrically provided with a top plate 14. The top box 12 is equipped with a heating box 15 inside. The heating box 15 is an existing device in transfer printing technology and is conventionally used in this device. Therefore, it should be equipped with a heating lamp or other heating device inside. This application does not elaborate on the heating box 15. Cylinders 16 are symmetrically fixedly connected to the bottom wall of the top plate 14. The output shaft of the cylinder 16 is connected to the top of the heating box 15. The tail end of the cylinder 16 is located inside the top plate 14 and is provided with a connecting pipe. The connecting pipe is connected to an external air source. The cylinder 16 is powered by the air supplied by the external air source. Support plates 2 are symmetrically installed on both sides of the working box 1. A bearing plate 3 is slidably installed on the top of the adjacent support plate 2. An upper closing plate 4 is movably connected to the top of the bearing plate 3. Spray pipes 5 are symmetrically fixedly installed at the bottom opening of the top box 12.

[0027] In practical application, this device, through the cooperation between the support plate 3 and the upper plate 4, allows the cabinet door to be placed inside the support plate 3. When the cabinet door is positioned between the support plate 3 and the upper plate 4, the transfer paper is placed on the surface of the cabinet door. A vacuum is drawn inside the support plate 3. Due to the uneven grooves on the surface of the cabinet door, the adhesion between the cabinet door and the transfer paper is uneven. This device is equipped with two pulleys 37 to uniformly draw air from both ends inside the support plate 3. When the transfer paper is adsorbed and adhered to the surface of the cabinet door, air is then introduced into the air supply pipe 33, causing the airbag 32 to be squeezed by the air pressure, pushing the cabinet door upward. Between the cabinet door and the transfer paper, due to the suction pressure of the pulleys 37 and the injection pressure of the air supply pipe 33, the transfer paper evenly fills the grooves on the surface of the cabinet door, achieving the effect of uniform coverage of the transfer paper.

[0028] The uniformly pressed support plate 3 and upper plate 4 are pushed between the bottom box 11 and the top box 12. Due to the position restriction of the pulley 37, the support plate 3 is ensured to slide in the center position. After sliding to a certain position, the cylinder 16 is activated. The cylinder 16 pushes the heating box 15 downward through the output shaft. The edge of the heating box 15 is evenly pressed on the edge of the upper plate 4. Then, the heating device inside the heating box 15 heats and transfers the transfer paper between the transfer paper and the cabinet door.

[0029] Please see Figures 1-2 The working box 1 has symmetrical slots 17 on both sides, the support plate 2 is snapped into the slot 17, the bottom end of the support plate 2 is fixedly installed with a support leg 21, the top surface of the support plate 2 is provided with a slide rail B23, and the two inner walls of the side plate 13 are provided with slide rails A18.

[0030] By setting slide rails B23 and A18, the position of the support plate 3 is restricted. When the support plate 3 is above the support plate 2, its bottom pulley 37 can only slide inside slide rail B23. After the pressing is completed, when it is pushed between the bottom box 11 and the top box 12, its side pulley 37 will slide into the slide rail A18, so that the support plate 3 slides in a straight line, restricting the sliding angle of the support plate 3 and preventing the position of the upper plate 4 from shifting when it is pressed with the heating box 15.

[0031] Please see Figures 1-4 The bearing plate 3 has an air pressure chamber 31 inside. An air bag 32 is fixedly connected to the top wall of the air pressure chamber 31. The air bag 32 is made of flexible material. An air supply pipe 33 is provided on one side of the bearing plate 3. The air supply pipe 33 is connected to the inside of the air pressure chamber 31. One end of the air supply pipe 33 is connected to the air compressor.

[0032] When the cabinet door is placed on the surface of the airbag 32, no air is injected into the air pressure chamber 31, and the cabinet door is placed stably. Then, the transfer paper is placed on the surface of the cabinet door, and the upper plate 4 is placed on top of the support plate 3, so that the space between the support plate 3 and the upper plate 4 is sealed. After the air is extracted using the air extraction pipe 36, compressed air is injected into the air supply pipe 33, causing the air supply pipe 33 to expand under force, pushing the cabinet door upward, making the connection between the cabinet door and the transfer paper tighter.

[0033] Please see Figures 1-4 The inner wall of the support plate 3 is inclined, which allows the membrane product to be better adsorbed on the inclined surface during vacuuming, reducing the air inside the support plate 3. The top of the support plate 3 is provided with a sealing silicone strip 35. One side of the support plate 3 is provided with a vacuum pipe 36 at both ends. The vacuum pipe 36 is connected to the vacuum pump through the end and is connected to the interior of the support plate 3. The two sides and the bottom of the support plate 3 are symmetrically installed with pulleys 37. The bottom pulley 37 slides inside the slide rail B23, and the side pulley 37 slides inside the slide rail A18 to limit the position of the support plate 3 and the upper plate 4.

[0034] When the support plate 3 and the upper plate 4 are closed, the air extraction pipe 36 is activated to evenly extract the air between them, so that the transfer paper is evenly adhered to the surface of the cabinet door. Since the inner wall of the support plate 3 is set as a slope, when the plastic pad 41 is pressed into the inside of the support plate 3, the angle between the plastic pad 41 and the inner wall of the support plate 3 is reduced, so that the air content between the support plate 3 and the upper plate 4 becomes smaller, and the plastic pad 41 can completely adsorb the transfer paper onto the surface of the cabinet door.

[0035] Please see Figures 1-4 The bottom wall of the upper plate 4 has a sealing groove at the position corresponding to the sealing silicone strip 35. A plastic pad 41 is installed inside the upper plate 4. The plastic pad 41 is made of flexible transparent material and has high temperature resistance.

[0036] During installation, the sealing groove of the upper plate 4 is installed in accordance with the sealing silicone strip 35 to achieve a seal between the sealing silicone strip 35 and the sealing groove. Then, the air between the support plate 3 and the upper plate 4 is extracted. After the plastic pad 41 is subjected to force, it is drawn into the interior of the support plate 3. Due to the adsorption and adhesion of the plastic pad 41, the transfer paper is evenly adhered to the surface of the cabinet door. Subsequently, the plastic pad 41 adheres more tightly to the inner wall slope of the support plate 3, resulting in a lower air content between the support plate 3 and the upper plate 4.

[0037] Please see Figures 1-2 The bottom of the nozzle 5 is uniformly equipped with nozzles 51 in a linear array, and the top of the nozzle 5 is provided with a transmission pipe 52, which is connected to an external air source.

[0038] After the heat transfer is completed, traditional transfer machines allow the material to cool naturally after heating, which is time-consuming. In this device, the nozzle 5 is used to cool the upper plate 4 and the cabinet door. After heating, the cylinder 16 drives the output shaft to retract, and at the same time moves the heating box 15 upward, so that the upper plate 4 is no longer pressed by the heating box 15. When the support plate 3 and the upper plate 4 are pulled out between the bottom box 11 and the top box 12, the external air source is introduced into the transmission pipe 52, so that compressed air is sprayed out from the nozzle 51. When the upper plate 4 is pulled out, the nozzle 51 sprays compressed air onto the surface of the upper plate 4, which quickly exchanges heat between the plastic pad 41 and the cabinet door, so that the temperature of the cabinet door and the plastic pad 41 drops rapidly, shortening the cooling rate of the plastic pad 41 and the cabinet door.

[0039] Working principle: In use, place the cabinet door above the airbag 32, then place the transfer paper on the surface of the cabinet door. Align the sealing groove of the upper plate 4 with the sealing silicone strip 35 and install them to create a seal between the support plate 3 and the upper plate 4. Connect the suction pipe 36 to the suction pump, and suction the air between the support plate 3 and the upper plate 4 through the suction pipe 36. Due to the negative pressure, the plastic pad 41 slowly adheres to the interior of the support plate 3. The plastic pad 41 then moves... During the dynamic bonding process, the transfer paper is squeezed between itself and the cabinet door, pressing the transfer paper until it adheres to the surface of the cabinet door. The inclined inner wall of the support plate 3 is tightly bonded to the plastic pad 41, creating a negative pressure state between the support plate 3 and the upper plate 4. Subsequently, the air supply pipe 33 is connected to the air compressor, and compressed air is introduced into the air pressure chamber 31 through the air supply pipe 33. The air bladder 32 expands under pressure, pushing the cabinet door upward, making the connection between the cabinet door and the transfer paper even tighter, thus achieving a seamless bond between the transfer paper and the cabinet door. The plates are evenly and perfectly fitted together. Then, the support plate 3 is pushed into the bottom box 11 and top box 12 from slide rail B23. When the side pulley 37 enters between the bottom box 11 and top box 12, it slides into slide rail A18 to limit the position of the support plate 3. After being pushed in to a certain extent, the cylinder 16 is connected to the external air source. The cylinder 16 is driven to push the output shaft downward, so that the edge of the heating box 15 is pressed against the edge of the upper plate 4. Then, the heating component inside the heating box 15 is activated to heat it. After heating is completed, the cylinder 16 is driven to retract the output shaft, so that the heating box 15 rises together. Then, the transmission pipe 52 is connected to the external air source. Compressed air is introduced into the nozzle 5 through the transmission pipe 52 and sprayed out from the nozzle 51. When the support plate 3 is pulled, the surface of the upper plate 4 is evenly cooled by the compressed air sprayed from the nozzle 51, and the temperature of the plastic pad 41 and the cabinet door is reduced to a suitable temperature. Then, the connection between the support plate 3 and the upper plate 4 is opened to complete the cabinet door transfer work.
