Description

Technical Field

[0001] This invention relates to the field of electroplating equipment technology, specifically a heating plate for printing equipment. Background Technology

[0002] A heating plate for printing equipment can be broadly defined as a specialized functional component installed on the printing media transport path of printing equipment (such as digital printers, photo printers, and inkjet printers) to heat the printing media (such as photographic paper, inkjet cloth, and film) by converting electrical energy into heat energy. Specifically, it is a device composed of heating elements (such as heating wires and heating films), heat-conducting structures (such as metal substrates and heat-conducting coatings), a temperature control system, and a mounting frame. Its core function is to heat and dry the printing media after ink printing, allowing the ink to solidify quickly, preventing ink smudging and sticking, and ensuring the clarity and color saturation of the printed pattern. Simultaneously, appropriate heating can also keep the printing media flat, avoiding printing deviations caused by media curling or wrinkling, and improving printing accuracy.

[0003] The core defects of existing heating plates used in printing equipment in practical applications lie in their low heat utilization efficiency and insufficient heating uniformity and temperature control accuracy, which seriously affect printing quality and equipment energy efficiency. Specifically, existing heating plates generally adopt a closed structure of "base + top shell," with a strip heating wire inside as the heat source. The heat generated by the heating wire dissipates in all directions. However, in the printing process, only the heat in the area where the top of the top shell contacts the printing medium is effective for ink drying and medium smoothing. The heat in other directions (such as the base side and the non-contact side of the top shell) is wasted, which increases equipment energy consumption and causes problems such as accelerated aging and unstable performance of the heating plate's surrounding components due to heat. At the same time, this type of heating plate is often a one-piece design, making it difficult to achieve absolutely uniform heat distribution from the heating wire. This easily leads to local overheating or underheating, resulting in uneven heating of the printing medium. In mild cases, this causes inconsistent ink drying, resulting in differences in color depth and smudging at the edges of the pattern. In severe cases, it causes the medium to curl and deform due to local overheating, seriously affecting printing accuracy. Summary of the Invention

An assembly groove is formed on the top of the top shell. A heat-conducting plate is fixedly connected to the inner wall of the assembly groove. A flexible heat-conducting pad is bonded between the bottom surface of the heat-conducting plate and the inner wall of the assembly groove. The top surfaces of the ribbon heating wires are all in contact with the bottom surface of the flexible heat-conducting pad.

[0006] Preferably, the flexible connecting strip is made of silicone, and several glass fiber filaments are embedded inside the flexible connecting strip, with the bottom surfaces of the several belt heating filaments all in contact with the top surface of the flexible connecting strip.

[0007] Preferably, the heat insulation board is made of asbestos, the outer surface of the heat insulation board is wrapped with fireproof aluminum foil, the ribbon heating wire is made of nickel-chromium alloy, and the outer surface of the ribbon heating wire is covered with a high-temperature resistant insulating sleeve.

[0008] Preferably, the flexible pad is made of silicone rubber, and the top surface of the flexible pad has a plurality of linearly arrayed embedding grooves. A plurality of the ribbon heating wires are respectively bonded to the inner wall of the plurality of embedding grooves, and the thickness of the ribbon heating wires is equal to the depth of the embedding grooves.

[0009] Preferably, the heat-conducting plate is made of aluminum alloy, and the top surface of the heat-conducting plate is coated with Teflon. The top surface of the heat-conducting plate and the top surface of the top shell are on the same horizontal plane.

[0010] Preferably, the flexible thermal pad is made of thermally conductive silicone, and the interior of the flexible thermal pad is filled with a number of alumina ceramic particles.

[0011] Preferably, the heat insulation board has connecting grooves at both its left and right ends, and the flexible connecting strip is bonded inside the connecting grooves. The depth of the connecting grooves is equal to the thickness of the flexible connecting strip.

[0012] Preferably, the top surface of the base is provided with an insertion groove, the heat insulation plate is inserted into the insertion groove, and the bottom surface of each heat insulation plate is fixedly connected with two symmetrically arranged positioning pins, both of which are inserted into the insertion groove.

[0013] Preferably, the inner wall of the insertion slot is provided with a plurality of symmetrically arranged snap-fit ​​grooves, and the plurality of snap-fit ​​protrusions are snapped into the heat insulation plate through the snap-fit ​​grooves.

[0014] Preferably, the top of the heat insulation board is fixedly connected with a plurality of linear array anti-slip strips, and the bottom surface of the flexible pad is provided with a plurality of anti-slip grooves adapted to the anti-slip strips, and the anti-slip strips are embedded and bonded inside the anti-slip grooves.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a heating plate for printing equipment, which has the following beneficial effects: 1. This printing equipment uses a heating plate. During operation, a nickel-chromium alloy ribbon heating wire generates heat. Its bottom surface is bonded to a flexible silicone connecting strip, and it is wrapped in asbestos insulation panels at the front and back. The top is embedded in a groove of a flexible silicone rubber pad, making close contact with a thermally conductive silicone flexible pad. The fire-retardant aluminum foil on the outer surface of the insulation panel and the flexible connecting strip form a closed, insulated space, preventing heat from diffusing to the non-working areas of the base and top shell. The heat generated by the ribbon heating wire is concentrated and rapidly conducted through the alumina ceramic particles inside the flexible thermal pad to the aluminum alloy heat-conducting plate, and then evenly transferred to the printing medium by the heat-conducting plate. Simultaneously, the linear array distribution of the ribbon heating wire and the positioning effect of the embedded groove ensure that the heat is evenly distributed along the width of the heat-conducting plate, avoiding localized overheating. This design reduces heat waste, lowers equipment energy consumption, ensures uniform heating of the printing medium, prevents uneven ink drying or media curling, and improves printing quality.

[0016] 2. The heating plate used in this printing equipment is precisely inserted into the base's insertion slot via positioning pins during assembly. The locking protrusions are then embedded into the locking grooves to secure the plate, ensuring a firm connection between the heat insulation plate and the base. A flexible pad is bonded to the top of the heat insulation plate via anti-slip strips and grooves, preventing displacement due to thermal expansion and contraction during heating. A flexible connecting strip is embedded in the connecting groove of the heat insulation plate, bonding to both ends of the base to form an integrated structure. Internal fiberglass filaments enhance tensile strength, preventing breakage during operation. During operation, the heating wire is contained within the groove, and the high-temperature insulating sleeve on the outer surface prevents short-circuit risks. The Teflon coating on the top surface of the heat-conducting plate prevents printing media adhesion, extending the plate's lifespan. Through multiple positioning and adapting connections, all components form a stable overall structure, reducing malfunctions caused by vibration or thermal deformation and extending the overall lifespan of the equipment.

[0017] 3. The heating plate used in this printing equipment requires the following installation steps: First, the base is fixed to the top shell using a snap-fit ​​method. Then, the ends of the base are connected using flexible connecting straps. Next, the heat insulation plate is inserted into the insertion slot and locked in place by the snap-fit ​​protrusions. Then, the flexible pad, heating wire, and flexible heat-conducting pad are assembled sequentially. Finally, the heat-conducting plate is fixed to complete the overall assembly. All components are connected by snap-fit ​​or adhesive methods, requiring no complex tools. When maintenance is needed, the base and heat insulation plate of the faulty area can be disassembled individually. Because the components are modularly assembled, only the flexible connecting straps need to be separated to remove the corresponding component and replace the heating wire or flexible pad, without disassembling the overall structure. This modular and convenient assembly design reduces installation difficulty, makes subsequent maintenance more efficient, reduces equipment downtime, and improves production efficiency.

The top surface embedding grooves 11 can accurately position the ribbon heating wires 7, and the thickness of the heating wires is equal to the depth of the grooves, so that the top surface of the heating wires is flat and fits the flexible heat-conducting pad 10, ensuring efficient heat transfer and uniform distribution.

[0025] As an optional technical solution of the present invention: the heat-conducting plate 9 is made of aluminum alloy, and the top surface of the heat-conducting plate 9 is coated with Teflon.

[0030] As an optional technical solution of the present invention: a number of linear array anti-slip strips 16 are fixedly connected to the top of the heat insulation plate 4, and a number of anti-slip grooves 17 adapted to the anti-slip strips 16 are opened on the bottom surface of the flexible pad 6. The anti-slip strips 16 are embedded and bonded inside the anti-slip grooves 17. The anti-slip strips 16 of the heat insulation plate 4 are embedded in the anti-slip grooves 17 of the flexible pad 6, which increases the contact friction between the two, prevents the flexible pad 6 from shifting due to thermal expansion and contraction during heating, ensures the fixed installation position of the belt heating wire 7, and ensures heating stability.

[0031] The heating plate of this printing equipment is used in accordance with the following steps: 1) The printing equipment uses a heating plate. When the equipment is working, the nickel-chromium alloy strip heating wire 7 is energized and heats up. Its bottom surface is attached to the flexible connecting strip 3 made of silicone material. It is wrapped with heat insulation board 4 made of asbestos material at the front and back. The top is embedded in the groove 11 of the flexible silicone rubber pad 6 and is in close contact with the flexible heat-conducting pad 10 made of thermally conductive silicone material.

[0032] 2) The fireproof aluminum foil on the outer surface of the heat insulation board 4 and the flexible connecting strip 3 form a closed heat insulation space, blocking heat from spreading to the non-working areas of the base 2 and the top shell 1.

[0033] 3) The heat generated by the belt heating wire 7 is concentrated and quickly conducted to the aluminum alloy heat-conducting plate 9 through the alumina ceramic particles inside the flexible heat-conducting pad 10, and then evenly transferred to the printing medium by the heat-conducting plate 9.

[0034] 4) Under the linear array distribution and positioning effect of the embedded groove 11, the heat of the ribbon heating wire 7 is evenly distributed along the width direction of the heat-conducting plate 9, avoiding local overheating.

[0035] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0036] In summary, the heating plate used in this printing equipment features a nickel-chromium alloy strip heating wire 7 that generates heat when energized. Its bottom surface is bonded to a flexible silicone connecting strip 3, and it is wrapped at the front and back by an asbestos insulation plate 4. The top is embedded in the groove 11 of a flexible silicone rubber pad 6, making close contact with a thermally conductive silicone flexible thermal pad 10. The fire-retardant aluminum foil on the outer surface of the insulation plate 4 and the flexible connecting strip 3 form a closed heat-insulating space, preventing heat from diffusing to the non-working areas of the base 2 and top shell 1. The heat generated by the strip heating wire 7 is concentrated and rapidly conducted through the alumina ceramic particles inside the flexible thermal pad 10 to the aluminum alloy thermal plate 9, and then evenly transferred to the printing medium by the thermal plate 9. Simultaneously, due to the linear array distribution of the strip heating wire 7 and the positioning effect of the groove 11, the heat is evenly distributed along the width of the thermal plate 9, avoiding localized overheating. This design reduces heat waste, lowers equipment energy consumption, ensures uniform heating of the printing medium, prevents uneven ink drying or medium curling, and improves printing quality. The printing equipment uses a heating plate. During assembly, the heat insulation plate 4 is precisely inserted into the insertion slot 13 of the base 2 via positioning pins 14, and the snap-fit ​​protrusion 5 is embedded into the snap-fit ​​groove 15 to complete the fixation, ensuring a firm connection between the heat insulation plate 4 and the base 2. The flexible pad 6 is bonded to the top of the heat insulation plate 4 through the cooperation of the anti-slip strip 16 and the anti-slip groove 17 to prevent displacement due to thermal expansion and contraction during heating. The flexible connecting strip 3 is embedded in the connecting groove 12 of the heat insulation plate 4 and bonded to the base 2 end to end to form an integral structure. The internal glass fiber filaments enhance the tensile strength and prevent breakage during equipment operation. During operation, the belt heating wire 7 is limited by the embedded groove 11, and the high-temperature resistant insulating sleeve on the outer surface avoids the risk of short circuit. The Teflon coating on the top surface of the heat-conducting plate 9 prevents the printing medium from sticking and extends the service life of the heat-conducting plate 9. All components are connected through multiple positioning and adaptation to form a stable overall structure, reducing failures caused by vibration or thermal deformation and extending the overall service life of the equipment. The heating plate used in this printing equipment is installed by first fixing the base 2 into the top shell 1 using a snap-fit ​​method, then connecting the ends of the base 2 with the flexible connecting strap 3. Next, the heat insulation plate 4 is inserted into the insertion slot 13 and locked in place by the snap-fit ​​protrusion 5. Then, the flexible pad 6, the heating wire 7, and the flexible heat-conducting pad 10 are assembled sequentially. Finally, the heat-conducting plate 9 is fixed to complete the overall assembly. All components are connected by snap-fit ​​or adhesive methods, requiring no complex tools. When maintenance is needed, the base 2 and heat insulation plate 4 in the faulty area can be disassembled individually. Because the components are modularly assembled, only the flexible connecting strap 3 needs to be separated to remove the corresponding component and replace the heating wire 7 or the flexible pad 6, without disassembling the entire structure. This modular and convenient assembly design reduces installation difficulty, makes subsequent maintenance more efficient, reduces equipment downtime, and improves production efficiency.
