[0025] Reference Figure 1-7 A printed product adhesion detection device comprises a detection platform 1, a lifting slot 2 is provided at the upper end of the detection platform 1, a lifting rod 3 is fixed to the inner wall of the lifting slot 2, the upper end of the lifting rod 3 is rotatably connected to a support plate 4, a flip box 5 is fixed to the side wall of the lifting rod 3, and a flip transfer mechanism for pushing the support plate 4 to flip is arranged inside the flip box 5, a transposition motor 6 is embedded in the side wall of the detection platform 1, a transposition shaft 7 is fixed to the output shaft of the transposition motor 6, a plurality of connecting plates 8 are fixed to the circumferential side wall of the transposition shaft 7, a pressing plate 9 is fixed to the side wall of each connecting plate 8, two temperature control boxes 10 are fixed to the side wall of the detection platform 1, a vortex tube 11 is fixed to the back of the detection platform 1, and the vortex tube 11 is connected to an external air compressor and outputs air to the outside after starting. The cold and hot air flows are discharged, and the cold and hot air outlet pipes of the vortex tube 11 are respectively connected to the cold flow pipe 13 and the hot flow pipe 12, and the cold flow pipe 13 and the hot flow pipe 12 are respectively connected to the inside of the two temperature control boxes 10, and the side walls of the two temperature control boxes 10 are penetrated with a slide groove 39, and the slide groove 39 makes way for the connecting plate 8 to ensure that the pressing plate 9 can rotate smoothly and can enter the temperature control box 10 for temperature adjustment. The hot air flow of the vortex tube 11 heats up the pressing plate 9 before detection to ensure the detection quality, and the cold air flow cools down the pressing plate 9 after detection, so that the temperature of the pressing plate 9 is restored, avoiding the continuous accumulation and increase of heat on the surface of the pressing plate 9 during continuous processing, thereby causing detection errors caused by different detection temperatures before and after, and ensuring the detection quality;

[0026] A detection slot 14 is provided on the side wall of the detection table 1, an acceleration slot 15 connected to the inside of the detection slot 14 is provided on the upper end of the detection table 1, a detection main shaft 16 and a detection auxiliary shaft 17 are rotatably connected to the inner wall of the detection slot 14, a detection motor 18 is fixed to the inner bottom of the detection slot 14, the output shaft of the detection motor 18 is fixed to the detection main shaft 16, the detection main shaft 16 and the detection auxiliary shaft 17 are jointly sleeved with a detection belt 40, a cleaning mechanism for cleaning the detection belt 40 is provided inside the detection slot 14, a conveying platform 34 is fixed to the side wall of the detection table 1, a wet conveying mechanism is provided on the upper end of the conveying platform 34, and a light-sensing opening and closing mechanism for automatic timing is provided on the upper end of the detection table 1;

[0027] The wet conveying mechanism includes a conveying main shaft 30 and a conveying auxiliary shaft 31 which are rotatably connected to the inner wall of the conveying platform 34. A conveying motor 32 is fixed to the side wall of the conveying platform 34. The output shaft of the conveying motor 32 is fixed to the conveying main shaft 30. The conveying main shaft 30 and the conveying auxiliary shaft 31 are jointly sleeved with a conveying belt 35. A plurality of humidifying nozzles 33 are inserted through the side wall of the conveying platform 34. The humidifying nozzles 33 are connected to an external water pump. The conveying motor 32 drives the conveying belt 35 to operate and convey the printed matter. During the process, the humidifying nozzles 33 spray water vapor to complete humidification, thereby improving the detection effect and realizing continuous assembly line processing.

[0028] The inner walls of the two temperature control boxes 10 are connected with a pair of baffles 36 through torsion springs, and the side walls of the detection platform 1 and the conveying platform 34 are fixed with a placement platform 19; the printed matter after the detection will be moved to the placement platform 19 for easy picking and centralized processing, and the pair of baffles 36 are composed of two pieces, one long and one short, located at the upper and lower ends of the temperature control box 10, and the positions of the baffles 36 in the two temperature control boxes 10 are also different. The position of the longer piece does not hinder the rotation of the pressing plate 9, and at the same time increases the blockage of the temperature control box 10, thereby improving the temperature control efficiency, while the shorter piece is used for the rotation and transfer of the pressing plate 9, and at the same time realizes the timely discharge of the airflow outward;

[0029] When the adhesion test of printed products is required, the printed products to be tested are placed on the conveyor belt 35, and then the conveying motor 32 is started to drive the conveying main shaft 30 to rotate, thereby driving the conveyor belt 35 to move, so that the printed products can be smoothly transferred. During the transfer of the printed products along the conveyor belt 35, the humidifying nozzle 33 will be pumped by the external water pump to spray out atomized water vapor, thereby achieving a certain degree of wetting treatment on the surface of the printed products;

[0030] Then the printed matter will be transferred to the top of the support plate 4. At this time, the lifting rod 3 can be started to extend and push the support plate 4 upward, so as to realize the upward push of the printed matter. Before this, the vortex tube 11 is started, so as to transport the hot air flow to the temperature control box 10 through the heat flow tube 12, so that the pressing plate 9 located inside the temperature control box 10 is continuously heated by the hot air flow, so that the temperature of the pressing plate 9 is effectively increased. At the same time as the lifting rod 3 is started, the transposition motor 6 will also be started to drive the heated pressing plate 9 to move to the top of the lifting rod 3.

[0031] Therefore, after the printed matter moves up, the upper end of the printed matter will be pressed against the heated pressing plate 9, and the lower end will be pressed against the supporting plate 4, thereby realizing the pressing process of the printed matter, and performing the heating and pressing process. After a certain period of time, the equipment is reset, and the processed printed matter is placed in the acceleration slot 15, so that the printed matter is accelerated to fall above the detection belt 40. Since the printed matter has a certain speed when falling, it can move downward along the detection belt 40 with sufficient kinetic energy. The detection motor 18 can be started to drive the detection spindle 16 to rotate, so that the detection belt 40 rotates, and the running direction of the detection belt 40 is opposite to the moving direction of the printed matter, thereby increasing the moving time of the printed matter, so that the moving time data is expanded to avoid the increase of the contrast error due to being too small. Since the surface viscosity of the printed matter increases after hot pressing, the friction between the printed matter of different viscosities and the surface of the detection belt 40 is different, resulting in differences in the movement speed. Therefore, by recording the time when the printed matter moves down, it is possible to judge whether the adhesion of the printed matter is qualified. The recorded data is used for judgment and quantitative processing, so that the result is more accurate.

[0032] Reference Figure 8 The flip transfer mechanism includes a heat conducting block 22 fixed to the inner wall of the flip box 5, a folded deformation strip 23 is fixed to the bottom of the heat conducting block 22, a push plate 24 is fixed to the bottom of the deformation strip 23, a button 25 abutting against the bottom of the push plate 24 is fixed to the inner bottom of the flip box 5, a flip push rod 26 is fixed to the inner bottom of the flip box 5, the deformation strip 23 is made of memory metal, and will become a straight strip after reaching the transformation temperature, and automatically restore after the temperature drops, and the flip box 5 is located at the side wall of the upper part of the lifting rod 3, and maintains an abutment state with the bottom of the support plate 4;

[0033] During the process of heating and pressing the printed matter, the heat conductive block 22 will absorb the heat transferred from the upper part and transfer the heat to the deformation strip 23. After reaching the transformation temperature, the deformation strip 23 will be transformed into a straight strip, thereby extending as a whole, and then pushing the push plate 24 to move downward. After the push plate 24 moves downward, it will form a pressing start for the button 25, so that the flip push rod 26 is electrically started. Therefore, when the subsequent lifting rod 3 shrinks and resets, the flip push rod 26 can extend and push the support plate 4 to flip, so that the printed matter above the support plate 4 slides down under the action of gravity, and will slide into the acceleration slot 15, realizing the automatic transfer of the printed matter, facilitating the subsequent quantitative judgment, and being more convenient as a whole, without the need for additional manual operation, reducing labor costs and improving detection efficiency.

[0034] Reference Figure 1 and Figure 4 , the light-sensitive opening and closing mechanism includes a starting light box 20 fixed to the upper end of the detection platform 1, a starting resistor 21 is embedded in the side wall of the detection platform 1, and the starting light box 20 corresponds to the starting resistor 21 in position. The upper end surface of the support plate 4 is a mirror surface, and a reflecting plate 27 and a terminal light box 28 are fixed to the inner bottom of the detection slot 14. The side wall of the detection slot 14 is embedded with a terminal resistor 29, and the terminal resistor 29 corresponds to the terminal light box 28 in position and is respectively located on both sides of the reflecting plate 27. The starting resistor 21 and the terminal resistor 29 are connected to the timer opening and closing circuit of the external device and are used to control the opening and closing of the timer of the external device. Light emitters are provided inside the starting light box 20 and the terminal light box 28, and the starting resistor 21 and the terminal resistor 29 are both photoresistors. After receiving light, the resistance value will change, so the light can be blocked to realize timely equipment opening and closing. The controlled equipment includes the start of the lifting rod 3 and the transposition motor 6, and the stop of the lifting rod 3 and the transposition motor 6 can be achieved by a timing device, a simple delay switch, etc. can also be achieved, which will not be repeated here;

[0035] Since the upper end surface of the support plate 4 is a mirror, when the printed matter moves to the upper part of the support plate 4, the mirror will be blocked, resulting in failure of light reflection, so that the light emitted from the starting light box 20 cannot be received by the starting resistor 21, resulting in a decrease in the resistance value of the starting resistor 21, allowing the device to start. Therefore, when the printed matter reaches the detection position, the detection process is automatically started and the timing starts. When the printed matter leaves the detection belt 40 after inspection, the reflective plate 27 will be blocked, so that the light emitted from the end light box 28 cannot be reflected to the position of the end resistor 29, causing the timer to stop, so that the timing process is automatically completed, and there is no error caused by human operation. The data is accurate, which improves the accuracy of equipment detection. After the printed matter leaves, the light resumes smooth reflection, and the equipment will return to its initial state, which can realize continuous automatic detection and facilitate continuous assembly line operation.

[0036] Reference Figure 3-4 The cleaning mechanism includes a bracket 37 fixed to the bottom of the detection tank 14, and a cleaning roller 38 is rotatably connected to the side wall of the bracket 37, and the upper end of the cleaning roller 38 abuts against the lower part of the detection belt 40;

[0037] As the detection belt 40 rotates continuously, it will continuously come into frictional contact with the cleaning roller 38 at the bottom, so that the cleaning roller 38 can continuously rotate to absorb and wipe the impurities remaining on the surface of the detection belt 40, effectively cleaning the residue of the printed matter, thereby ensuring the effectiveness of the continuous operation of the detection belt 40.
