[0004] The above-mentioned prior art solutions have the following defects: there is no device that can quickly dry the ink, the window patching machine operates at a high speed, and the printing of graphics and texts on the window film is often at the end of the process. During the stacking process after the processing is completed, problems such as adhesion and ink deformation of the finished product are likely to occur, affecting the yield rate. Utility Model Content

[0005] The utility model aims to provide an automatic window pasting machine with a picture and text printing function to solve the problems existing in the above-mentioned prior art.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] An automatic window patching machine with a graphic printing function, the main body of the window patching machine comprises a workbench and a heating device, a conveyor belt is arranged on the top of the workbench, the conveyor belt is transported in a left-right direction, and a heating device for heating the left end of the conveyor belt is arranged on the top of the workbench;

[0008] The heating device includes a housing and an electric heating tube. An avoidance groove is provided at the bottom end of the housing for the conveyor belt to pass through. A heat insulation layer is provided on the inner wall of the housing. A plurality of electric heating tubes are provided, and the plurality of electric heating tubes are evenly distributed at the inner top end of the housing.

[0009] By adopting the above technical solution, since the left end of the conveyor belt is arranged inside the housing of the heating device, the heating device can dry the printed matter transported at the left end of the conveyor belt from multiple directions, thereby accelerating the drying and solidification speed of the graphic pigments on the surface of the window film. The heat insulation layer on the inner wall of the heating device uses encrypted aluminosilicate rock wool, which has the characteristics of incombustibility and strong heat insulation, can minimize the temperature impact of the heating device on the overall production line and production space, reduce energy consumption at the same time, and the evenly distributed electric heating tubes can evenly distribute heat to the bottom end of the heating device, ensuring that the drying speed of each part of the window film passing through the herringbone mesh belt below the heating device is consistent, avoiding situations such as adhesion and bonding when subsequent packaging boxes are stacked, and greatly improving the yield rate.

[0010] In a further embodiment, the electric heating tube includes a tube body, an electric heating wire and a sealing block. One end of the tube body is completely open, a sealing block is provided at the open end of the tube body, the electric heating wire is arranged inside the tube body, and a filling material for heat conduction is arranged inside the tube body.

[0011] By adopting the above technical solution, the tube body of the electric heating tube is also made of a stainless steel heating tube. The stainless steel heating tube has the advantages of dust-free durability, rapid and uniform drying effect, a service life of more than 10,000 hours, safety and reliability. The electric heating wire is spirally arranged along the central axis of the tube body. The magnesia sand filled in the tube body can evenly transfer heat to the tube body of the stainless steel heating tube, and also greatly increases the contact area between the electric heating wire and the magnesia sand. The magnesia sand has good heat conduction performance and also has a flame retardant effect.

[0012] In a further embodiment, an internal thread is provided at the open end of the tube body, and an external thread corresponding to the internal thread is provided on the sealing block.

[0013] By adopting the above technical solution, the sealing block is mainly used to block the tube body. The material of the sealing block is alumina ceramic. Alumina ceramic is a high-temperature structural material with good prospects, having the advantages of high melting point and high hardness. By milling teeth on the surface of the sealing block with a T-shaped diamond grinding rod, an accurately sized external thread can be processed, which is convenient for matching with the internal thread at the open end of the tube body, greatly accelerating the subsequent assembly speed, and at the same time improving the sealing performance of the electric heating tube, avoiding the problem that the leakage of the internal magnesia sand affects the operation of the device.

[0014] In a further embodiment, the outer shell is composed of a frame body, a front plate, a rear plate, a left side plate, a right side plate and a top plate. The left side plate and the right side plate are both hingedly connected to the frame body, and a handle is provided at the top end of the left side plate.

[0015] By adopting the above technical solution, for the convenience of inspection and maintenance, the left side plate and the right side plate of the outer shell are hinged to the frame body, and the frame bodies on both sides can be opened through the handle, so that the electric heating tube and the herringbone conveyor belt can be visually seen and contacted, facilitating the operation of maintenance personnel.

[0016] In a further embodiment, a receiving groove is provided on the inner wall of the outer shell, and the receiving groove is used for receiving a support plate made of stainless steel.

[0017] By adopting the above technical solution, the outer shell itself is made of cold-rolled steel plates, and the outer shell of the heating device itself is mainly composed of metal. When the metal is in a high-temperature state for a long time, corrosion will inevitably occur. Although the drying of the window film of the packaging box does not require a temperature that will cause high-temperature corrosion, considering the service life of the device, an anti-corrosion coating is set by spraying on the surface of the support plate. This coating can effectively prevent the metal outer shell from being corroded during the long-term high-temperature process.

[0018] In a further embodiment, a control terminal is provided at the top end of the outer shell, and the control terminal is used for real-time adjustment of the heating device.

[0019] By adopting the above technical solution, the control terminal can adjust the temperature maintained by the heating device in real time. The on-site operator can adjust the temperature according to the drying degree of the printing ink in real time. Since the printed picture size and the number of words are different, the required temperature also varies. The lower the temperature maintained by the heating device, the less energy consumption, which plays a role in reducing production costs.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. Since the left end of the conveyor belt is arranged inside the outer shell of the heating device, the heating device can dry the printed matter transported at the left end of the conveyor belt from multiple directions, thereby accelerating the drying and solidification speed of the graphic pigments on the surface of the window film. The heat-insulating layer on the inner wall of the heating device uses encrypted aluminum silicate rock wool, which has the characteristics of incombustibility and strong heat insulation, can minimize the temperature influence of the heating device on the overall production line and production space, and at the same time reduces energy consumption. The uniformly arranged electric heating tubes can evenly distribute the heat to the bottom end of the heating device, ensuring that the drying speed of each part of the window film passing through the herringbone mesh belt below the heating device is the same, avoiding situations such as adhesion and bonding when stacking subsequent packaging boxes, and greatly improving the yield rate;

[0022] 2. Through the settings of the electric heating tube and the filling material, the resistance wire can be in full contact with the magnesia sand filled in the tube body. The thermal conductivity of the magnesia sand is much higher than that of air, and it can also play a role in insulating safety protection. The resistance wire is not straightly arranged inside the tube body, but spirally arranged along the central axis of the tube body inside the tube. This setting method can greatly increase the contact area between the resistance wire and the magnesia sand, thereby achieving the effect of increasing the heating efficiency of the electric heating tube;

[0023] 3. Through the setting of the control terminal, the temperature currently maintained by the heating device can be intuitively understood. Then, based on the drying degree of the ink on the window film of the packaging box, the temperature maintained by the heating device can be adjusted. Since the areas of the printed characters and patterns on different window films of the packaging box are different and the drying efficiencies are also different, the on-site operator can adjust the temperature of the heating device according to actual needs, achieving the effects of environmental protection, energy conservation, reducing energy consumption and production costs.

[0030] Embodiment:

[0031] As Figure 1-2 shown, an automatic window pasting machine with graphic printing function includes a window pasting machine body 1, characterized in that: the window pasting machine body 1 includes a workbench 2 and a heating device 3. A conveyor belt 4 is arranged on the top of the workbench 2, and the transportation direction of the conveyor belt 4 is the left-right direction. A heating device 3 for heating the left end of the conveyor belt 4 is arranged on the top of the workbench 2; the heating device 3 includes a housing 31 and electric heating tubes 32. An avoidance groove for the conveyor belt to pass through is arranged at the bottom end of the housing 31, and a heat insulation layer is arranged on the inner wall of the housing 31. A plurality of electric heating tubes 32 are arranged, and the plurality of electric heating tubes 32 are evenly arranged at the inner top end of the housing 31. The conveyor belt 4 is used to move the workpiece on the top of the workbench 2 from right to left. After printing glue, pasting film and graphic printing are completed, the graphic printing on the window film is completed, but the ink is not dry. At this time, if these finished product packaging boxes are directly stacked and stored, it is very easy to have the situation of adhesion, greatly increasing the probability of waste products. Because the left end of the conveyor belt is located inside the housing of the heating device, the printed matter will be dried by the heating device at the left end of the conveyor belt, and the high-temperature air will respectively contact the top and bottom of the finished product packaging box, affecting the graphic ink on the window film of the finished product packaging box from two directions, so that the ink dries quickly. A plurality of electric heating tubes 32 are arranged, and the electric heating tubes 32 are evenly arranged at the inner top end of the housing 31. The plurality of evenly arranged electric heating tubes can ensure that each finished product packaging box receives the same amount of heat when passing through the open end at the bottom of the housing, and there will be no uneven drying situation. After being completely dried and then stacking the finished product packaging boxes together, the yield can be effectively improved.

[0032] As Figure 1-2As shown, a heat insulation layer is provided on the inner wall of the outer shell 31, which can reduce the speed of heat conduction and dissipation, reduce energy loss. The heat insulation layer is composed of aluminosilicate rock wool. The main component of aluminosilicate rock wool is aluminosilicate, which has certain elasticity and corrosion resistance. A receiving groove is provided on the inner wall of the outer shell 31 for receiving a support plate 9 made of stainless steel. In addition to its own corrosion resistance, the surface of the stainless steel support plate 9 is provided with an anti-corrosion coating through powder spraying treatment. Metals will show certain corrosion when in a high-temperature state for a long time. Although the aluminosilicate rock wool has a low heat capacity and thermal conductivity, it will still continuously conduct heat to the outer shell. At this time, the stainless steel support plate and the anti-corrosion coating on the surface of the support plate can effectively delay the corrosion process of the outer shell and improve the overall service life of the heating device. The outer shell 31 is composed of a frame body, a front plate, a rear plate, a left side plate, a right side plate and a top plate. Although the sizes of these plates are different, they are all provided with receiving grooves, and support plates are embedded in the receiving grooves. And a heat insulation layer is also provided on the support plate. The heat insulation layer is flexible. The left side plate and the right side plate are both hingedly connected to the frame body. A handle 8 is provided at the top end of the left side plate. This handle is part of a safety lock. By turning the handle 8, the restriction of the safety lock can be released, and the left side plate can be opened downward in cooperation with the hinge. A handle 8 is also provided at the same position of the right side plate to ensure that the heating device 3 can be opened from both sides, which is convenient for maintenance and emergency repair by maintenance personnel.

[0033] As Figure 3 shown, the electric heating tube 32 includes a tube body 5, an electric heating wire 6 and a sealing block 7. The tube body 5 is also made of stainless steel and has the characteristics of high temperature resistance and corrosion resistance. The stainless steel heating tube has the advantages of dust-free and durable, and the drying effect is rapid and uniform. One end of the tube body 5 is completely open, and an internal thread is provided at the open end of the tube body 5. The sealing block 7 is provided with an external thread corresponding to the internal thread. The tube body 5 and the sealing block 7 can be effectively fastened by threads to speed up the installation speed and improve production efficiency. The material of the sealing block 7 is alumina ceramic, which has a high melting point and high hardness. By using a T-shaped diamond grinding rod to mill teeth on the surface of the sealing block 7, an external thread with precise dimensions can be processed. The electric heating wire 6 is arranged inside the tube body 5. The electric heating wire 6 converts electrical energy into heat energy. Since the thermal conductivity of air is poor, a filling material for heat conduction is arranged inside the resistance wire tube body 5. The filling material is magnesia sand, which has high fire resistance and insulation performance, and at the same time has excellent thermal conductivity, which can effectively enhance the heat conduction speed and efficiency of the electric heating wire 6. The resistance wire 6 is spirally arranged along the central axis of the tube body 5 inside the tube body 5. This arrangement can greatly increase the contact area between the resistance wire and the magnesia sand, making the heating efficiency of the electric heating tube 32 higher.
