Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, and in particular to an infrared drying component. Background Technology

[0002] When a printer prints on a canvas, the canvas needs to be dried before and after printing. Before printing, drying removes residual moisture from the substrate to prevent ink from spreading or reducing adhesion during printing. After printing, drying evaporates the solvent to prevent color bleeding and peeling, and cures the ink to prevent fading.

[0003] Infrared drying devices are typically used to dry canvases, but these devices dry the canvases by directly irradiating them with infrared heating elements, resulting in a slow drying process. Utility Model Content

[0004] The purpose of this invention is to provide an infrared drying component to increase the drying speed of canvas.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An infrared drying assembly includes a drying table with a protective net. Below the protective net is a compartment for placing infrared lamps. The assembly also includes a cavity located below the protective net. The upper opening of the cavity is fixedly connected to the protective net. The compartment is located inside the cavity. Multiple rows of fans are fixedly connected to the bottom surface of the cavity, with multiple fans in each row. The fans are located below the compartments, and the cavity has air vents at the connection points with the fans.

[0006] Using the above technical solution, the printed or unprinted canvas is placed on the upper surface of the protective net on the drying table. The infrared rays emitted by the infrared lamp tube pass through the protective net and irradiate the canvas. At the same time, the fan blows air onto the canvas. By heating and blowing air at the same time, the moisture (or residual solvent after printing) on ​​the canvas evaporates and dries quickly, thereby increasing the drying speed.

[0007] Preferably, a plurality of support feet are provided between the bottom of the compartment and the bottom of the cavity, and the upper and lower ends of the support feet are fixedly connected to the bottom of the compartment and the bottom of the cavity, respectively.

[0008] Using the above technical solution, the support feet are used to support the inside of the cavity and prevent the cavity from deforming due to the tension generated by the weight of the fan or other external forces.

[0009] Preferably, horizontal inner edge pieces are integrally formed around the perimeter of the upper opening of the cavity, and the inner edge pieces are located inside the cavity opening. The two sides of the receiving plate contact the inner edge pieces located in the length direction of the cavity. The connecting assembly includes connecting pieces and fasteners. Connecting pieces are provided on both sides of the width direction and both sides of the length direction of the protective net. The connecting pieces on both sides of the width direction of the protective net contact the upper surface of the protective net. The connecting pieces on both sides of the length direction of the protective net and the protective net contact the part that contacts the placement plate. The fasteners fix the protective net, the compartment and the cavity together.

[0010] By adopting the above technical solution, the fasteners exert pressure on the connecting plates. The connecting plates on both sides of the width direction of the protective net push the protective net to press against the placement plate. The connecting plates on both sides of the length direction of the protective net push the protective net and the placement plate to press against the inner edge plates on both sides of the opening of the cavity, thereby fixing the protective net and the cavity together. The connecting plates can increase the area of ​​pressure generated by the fasteners on the protective net, thereby increasing the fixing effect between the protective net, the compartment and the cavity.

[0011] Preferably, there are multiple compartments, each compartment including a receiving plate that has been continuously bent to form multiple grooves on itself. The receiving plate surfaces on both sides of the opening of each groove are connected to a protective net. Each groove of the receiving plate and the portion of the protective net located above the groove opening form a compartment for placing an infrared lamp tube. The two side edges of the receiving plate contact the two sides of the cavity opening along its length, respectively. The receiving plate has multiple through holes for ventilation.

[0012] Using the above technical solution, the number of infrared lamp compartments that are turned on varies depending on the size of the canvas. The larger the canvas area, the more infrared lamp compartments are turned on, and vice versa. When the fabric is placed on the protective net for drying, the infrared lamps in the compartments not covered by the canvas can be turned off, saving costs.

[0013] Preferably, the connecting piece is divided into connecting piece one and connecting piece two. Connecting piece one is located on both sides of the width direction of the protective net. Connecting piece one is straight and contacts the upper surface of the protective net. The protective net and the cavity are fixedly connected together by fasteners. Connecting piece two is L-shaped. The two sides of connecting piece two contact the outer wall of the cavity and the part of the protective net that contacts the receiving plate, respectively. Connecting piece two, the protective net and the cavity are fixed together by fasteners.

[0014] By adopting the above technical solution, the two sides of the protective net in the length direction are longer than the two sides in the width direction. By making the two sides of the connecting piece 2 contact the protective net and the two sides of the cavity in the length direction respectively, the contact parts of the protective net, the partition and the cavity in the length direction can be better limited, so that the two sides of the protective net, the partition and the cavity in the length direction are more firmly connected.

[0017] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0018] See Figure 1 , Figures 6 to 9An infrared drying assembly includes a drying table, which comprises a protective net 1, compartments, and a cavity 2. Horizontal inner edge pieces 7 are integrally formed around the perimeter of the upper opening of the cavity 2, and these inner edge pieces 7 are located inside the opening of the cavity 2. The upper opening of the cavity 2 has multiple rows of compartments for placing infrared lamps 11. The portion of each compartment for placing the infrared lamps 11 is located inside the cavity 2. Each compartment includes a receiving plate 5, which is a metal plate formed by continuous bending. The two sides of the receiving plate 5 contact the inner edge pieces 7 located along the length of the cavity 2. The protective net 1 is located above the receiving plate 5. The receiving plate 5 on both sides of the opening of each groove 6 is connected to the protective net 1. Each groove 6 of the receiving plate 5 and the part of the protective net 1 located above the opening of the groove 6 form a compartment for placing the infrared lamp tube 11. The cross-section of the groove 6 is trapezoidal. When the light of the infrared lamp tube 11 shines on the inclined side wall of the groove 6, the side wall of the groove 6 will reflect part of the light upward and shine it on the canvas placed on the protective net 1, making the light more concentrated and increasing the light intensity on the canvas. The receiving plate 5 has multiple through holes 10 for ventilation. The protective net 1, the receiving plate 5 and the cavity 2 are fixedly connected together by a connecting component.

[0019] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 10 The connecting components include connecting pieces and fasteners. There are multiple connecting pieces. Connecting pieces are provided on both sides of the width direction and both sides of the length direction of the protective net 1. The connecting pieces are divided into connecting piece 1 8 and connecting piece 2 9. Connecting piece 1 8 is located on both sides of the width direction of the protective net 1. Connecting piece 1 8 is straight and contacts the upper surface of the protective net 1. Connecting piece 2 9 is L-shaped. The two sides of connecting piece 2 9 contact the outer wall of the cavity 2 and the part of the protective net 1 that contacts the inner edge piece 7, respectively. The fasteners are used to fix the protective net 1, the compartment and the cavity 2 together.

[0020] See Figure 1 , Figure 2 , Figure 6 and Figure 10The fastener can be a rivet nut, bolt, or nut. When the fastener is a rivet nut, in the width direction of the protective net 1, the rivet nut is passed through the connecting piece 8, the hole of the protective net 1, and the inner edge piece 7 in the length direction of the cavity 2 in sequence. In the length direction of the protective net 1, the rivet nut is passed through the connecting piece 9, the protective net 1, the receiving plate 5, and the cavity 2 in sequence. Then, the rivet nut is deformed by the rivet gun. The deformed part of the rivet nut abuts against the inner edge piece 7 of the cavity 2, and the outer edge of the end of the rivet nut abuts against the connecting piece, thereby fixing the cavity 2, the compartment, and the protective net 1 together. When the fasteners are bolts and nuts, first pass the bolts through the inner edge plate 7 of the cavity 2 from bottom to top. Then, place the receiving plate 5, the protective net 1, and the connecting plate above the opening of the cavity 2 in sequence. Then, pass the bolts in the width direction of the cavity 2 through the holes on the protective net 1 and the connecting plate 8. Pass the bolts in the length direction of the cavity 2 through the receiving plate 5, the protective net 1, and the connecting plate 9 of the compartment in sequence. Then, thread the nut onto the bolt and tighten the bolt and nut so that the nut and the tail of the bolt press against the connecting plate and the inner edge plate 7 respectively, thereby fixing the protective net 1, the compartment, and the cavity 2 together. Alternatively, bolts can be used alone. By creating threaded holes in the inner edge plate 7, the bolts are threaded to the inner edge plate 7. The bolts on the inner edge plate 7 in the width direction of the cavity 2 pass through the holes in the protective net 1 and the connecting piece 8. The bolts are tightened so that their tails press against the connecting piece 8. The bolts on the inner edge plate 7 in the length direction of the cavity 2 pass through the receiving plate 5 of the compartment, the protective net 1, and the connecting piece 9 in sequence. The tails of the bolts press against the connecting piece 9, thereby fixing the protective net 1, the compartment, and the cavity 2 together.

[0021] See Figures 5 to 9 Multiple rows of fans 3 are fixedly connected to the bottom surface of the cavity 2, with multiple fans in each row. The fans 3 are located below the compartment, and the cavity 2 has an air vent at the connection between it and the fans 3.

[0022] See Figure 7 and Figure 9 Multiple support feet 4 are provided between the bottom of the compartment and the bottom of the cavity 2. The upper and lower ends of the support feet 4 are fixedly connected to the bottom of the compartment and the bottom of the cavity 2, respectively. The support feet 4 are used to support the inside of the cavity 2 and prevent the cavity 2 from deforming due to the pulling force generated by the weight of the fan 3 on the cavity 2 or other external forces.

[0023] Working principle: Place the printed or unprinted canvas on the upper surface of the protective net 1 of the drying table, turn on the infrared lamp in the compartment covered by the canvas, and the infrared rays emitted by the infrared lamp tube 11 pass through the protective net 1 and irradiate the canvas. At the same time, the fan 3 blows air onto the canvas. By heating and blowing air at the same time, the moisture (or residual solvent after printing) on ​​the canvas evaporates and dries quickly, thereby increasing the drying speed.
