DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5As shown, a flat screen printing machine includes a track 1, the number of which is two, and legs 2 are fixedly connected to both sides of the bottom of the track 1. Since there are two tracks 1, there are four legs 2, which are symmetrically distributed on both sides of the bottom of the track 1. The legs 2 can support the track 1 to keep it away from the ground, and one side of the top of the track 1 is fixedly connected to a feed shell 3, and the top and bottom of the feed shell 3 are both open-shaped designs. The feed shell 3 can temporarily store substrates to be printed, and the inner cavity of the track 1 is an L-shaped chute design. After the substrate is placed on the feed shell 3, it will fall into the L-shaped chute of the track 1. A chute shell 4 is fixedly connected between the legs 2, and the number of the chute shells 4 is two. A slide plate 5 is slidably connected between the slide chute shells 4, and a double-axis motor 8 is installed on one side below the slide chute shell 4. Two output shafts are provided on both sides of the double-axis motor 8. The two output shafts are controlled by independent driving systems to realize their respective movements. One of the output shafts of the double-axis motor 8 is provided with a connecting rod component 9, and the connecting rod component 9 is used in conjunction with the slide plate 5. The connecting rod component 9 includes a connecting shaft and a connecting rod. One end of the connecting shaft is fixedly connected to the output shaft of the double-axis motor 8, and one end of the connecting rod is rotatably connected to the other end of the connecting shaft. The other end of the connecting rod is hinged to the bottom of the slide plate 5 through a support. When the double-axis motor 8 provides driving force, the slide plate 5 can be driven in the inner cavity of the slide chute shell 4 through the action of the connecting rod component 9. The slide plate 5 is provided with a toggle mechanism 6 on the top of the slide plate 5. When the slide plate 5 moves back and forth, the toggle mechanism 6 can toggle the substrate placed in the feed shell 3 to achieve the material taking effect, and can keep the substrate on the track 1 for unidirectional pushing. One side of the track 1 is fixedly connected with a side plate 12. One side of the side plate 12 is provided with a printer body 10. The printer body 10 can print on the surface of the substrate through a screen mold. A hot air blower 13 is installed on the other side of the side plate 12. The hot air blower 13 can blow out high-temperature hot air to quickly dry the paint on the surface of the substrate. The inner wall of the track 1 is provided with a limiting mechanism 7. The number of the limiting mechanisms 7 is two, and they are respectively connected to the printing plate 1 and the printing plate 1. The positions of the machine body 10 and the hot air blower 13 correspond to each other. The limiting mechanism 7 can temporarily limit the printing substrate after it moves on the track 1, which can improve the printing accuracy and drying effect of the printing substrate. A storage shell 14 is provided on one side of the track 1. Under the action of the toggle mechanism 6, the printing substrate can be pushed to fall into the storage shell 14 for centralized storage. The other output shaft of the dual-axis motor 8 passes through the outer side of the side plate 12 and is rotatably connected to its inner wall. The inner cavity of the storage shell 14 is installed with a slow-down mechanism 11. The slow-down mechanism 11 is used in conjunction with the other output shaft of the dual-axis motor 8 to receive the continuously falling printing substrate, thereby reducing the impact force on the printing substrate when it falls and reducing the damage to the printing substrate.

[0021] The toggle mechanism 6 includes an articulated seat 61, which is fixedly connected to the top of the slide plate 5. There are three articulated seats 61, which correspond to the positions of the feed shell 3, the printer body 10 and the hot air blower 13 respectively. The inner wall of the articulated seat 61 is rotatably connected with a rotating shaft 62, and the surface of the rotating shaft 62 is fixedly connected with an L-shaped plate 63. Torsion springs 64 are arranged on the surface of the rotating shaft 62 and on both sides of the L-shaped plate 63. One end of the torsion spring 64 is fixedly connected to the articulated seat 61, and the other end of the torsion spring 64 is fixedly connected to the L-shaped plate 63. A longer groove for discharging substrates is provided at the bottom of one side of the feed shell 3, and a shorter groove is provided at the bottom of the other side of the feed shell 3. When the slide plate 5 slides toward the feed shell 3, the long end of the L-shaped plate 63 will first contact the substrate in the feed shell 3 through the long groove of the feed shell 3. Then the L-shaped plate 63 will tilt and rotate, and then it will slide with the bottom of the substrate until the L-shaped plate 63 moves to the outside of the feed shell 3. Under the action of the torsion spring 64, the L-shaped plate 63 can be restored to its initial position, and when the slide plate 5 slides toward the storage shell 14, the short side of the L-shaped plate 63 abuts against the surface of the slide plate 5. At this time, the long side of the L-shaped plate 63 will move the substrate away from the feed shell 3 through the short groove of the feed shell 3, so that the substrate moves along the inner wall of the track 1 to the position of the printer body 10 for the printing process. The two sides of the L-shaped plate 63 are hinged with connecting plates 65, and the connecting plates 65 can keep the three L-shaped plates 63 rotating synchronously, so that the substrate can move on the track 1 in sequence, and when passing through the printer body 10 and the hot air blower 13, the corresponding printing and drying operations can be obtained.

[0022] The limiting mechanism 7 includes a receiving groove 71, which is located on the inner wall of the track 1. The inner wall of the receiving groove 71 is in a T-shape. The bottom of the receiving groove 71 passes through the bottom of the track 1. The inner wall of the receiving groove 71 is slidably connected with a T-shaped block 72. The height of the T-shaped block 72 is less than the height of the inner wall of the receiving groove 71. When not in operation, the T-shaped block 72 can extend to the bottom of the track 1 through the receiving groove 71 under the action of its own weight. Both sides of the top of the slide plate 5 are fixedly connected with protrusions 73. The protrusions 73 Corresponding to the position and number of the T-shaped blocks 72, the bottom of the T-shaped block 72 and the top of the protrusion 73 are both arc-shaped. When the slide plate 5 drives the protrusion 73 to move to the storage groove 71, the protrusion 73 will push the T-shaped block 72 upward to limit the printing material sliding on the track 1, which can prevent the printing material from sliding excessively during the sliding process and causing deviation from the printer body 10 and the position of the printer body 10, thereby improving the printing accuracy and drying effect of the substrate.

[0023] The slow-down mechanism 11 includes a support plate 111, which is slidably connected to the inner wall of the material storage shell 14. The support plate 111 can carry the fallen substrate. The material storage shell 14 is designed to be open on three sides, which is convenient for the staff to take out the substrate. The two sides of the support plate 111 are fixedly connected with U-shaped frames 112 through the openings of the material storage shell 14. The material of the U-shaped frame 112 is nickel-iron alloy. An electromagnet 113 is installed on one side of the material storage shell 14. The inner wall of the U-shaped frame 112 is slidably connected to the surface of the electromagnet 113. When the electromagnet 113 is opened, the electromagnet 113 is opened. When it is started, the U-shaped frame 112 can be attracted by magnetic force, so that the height of the support plate 111 can be limited, so as to reduce the phenomenon of damage caused by the substrate falling too high. A linkage component 114 is provided on one side of the side panel 12. The linkage component 114 is used in conjunction with the dual-axis motor 8. It can automatically and slowly lower the height of the support plate 111 during the printing process, so that it can adapt to the height of the substrates continuously piled on the support plate 111, so that the substrates can fall smoothly on the support plate 111 for unified collection.

[0024] The linkage assembly 114 includes a rotating column 1142, one end of which passes through the outer side of the side plate 12 and is rotatably connected to the inner wall thereof, and the other end of the rotating column 1142 is fixedly connected to one side of the leg 2 through a connecting plate, and a linkage component 1141 is provided on the outer side of the side plate 12, and the linkage component 1141 includes a driving pulley, a passive pulley and a belt, the driving pulley is fixedly connected to the output shaft of the dual-axis motor 8, and the passive pulley is fixedly connected to one end of the rotating column 1142, and the belt is movably connected to the surfaces of the driving pulley and the passive pulley, when the dual-axis motor 8 drives the driving pulley to rotate, the rotational force can be transmitted to the passive pulley through the belt, so that the rotating column 1142 rotates together, and a half gear 1143 is fixedly connected to the surface of the rotating column 1142, and the number of the half gears 1143 is two and they are symmetrically distributed, and a rack plate 1144 is fixedly connected to one side of the U-shaped frame 112 The length of the rack plate 1144 is adapted to the height of the material storage shell 14, and the number and position of the rack plate 1144 correspond to the half gear 1143. When the linkage component 1141 drives the rotating column 1142 to rotate, the half gear 1143 can be meshed with the rack plate 1144, so that the rack plate 1144 can generate a downward thrust, so that the U-shaped frame 112 can continuously move downward on the surface of the electromagnet 113, and then the support plate 111 can catch the continuously falling substrates and slowly move to the bottom of the inner cavity of the material storage shell 14, which can not only shorten the falling distance of the substrates, but also enable the subsequent falling substrates to fall smoothly in the material storage shell 14 for centralized placement. Both sides of the material storage shell 14 are fixedly connected with the light rod 15 through the support plate, and the light rod 15 is slidably connected to the U-shaped frame 112, which can lift the support plate 111 to keep it stable during the movement inside the material storage shell 14.

[0025] It is worth noting that the printer body 10, the hot air blower 13 and the electromagnet 113 proposed in this technical solution are all existing technologies, and their working principles and beneficial effects when used are not described in detail here.

[0026] Working principle: First, place the printing material inside the feed shell 3, then start the double-axis motor 8 to drive the slide plate 5 to move back and forth in the inner cavity of the slide housing 4 through the connecting rod component 9. At this time, through the cooperation of the L-shaped plate 63 and the torsion spring 64, the printing material in the feed shell 3 can be moved one-way along the track 1 in sequence, so that the printing material can be printed and dried when passing through the printer body 10 and the hot air blower 13 in sequence. At the same time, the protrusion 73 will hit the T-shaped block 72 to make it rise in the storage groove 71 and protrude from the inner wall of the track 1, so that the printing or drying substrate can be The material is limited, and then the electromagnet 113 is started. When the dual-axis motor 8 drives the rotating column 1142 and the half gear 1143 to rotate through the linkage component 1141, the rack plate 1144 can be engaged to move it downward, so that the support plate 111 slowly moves downward with the substrate. After the support plate 111 is full of substrates and falls to the lowest point of the storage shell 14, the staff needs to take out the substrates in a unified manner. At this time, the electromagnet 113 can be temporarily turned off to make its magnetic force disappear, and then the support plate 111 is pulled up to the highest point of the storage shell 14 to continue to receive the substrates.
