[0031] In this embodiment, the limiting mechanism 3 includes a limiting plate 31, a limiting groove 32 is provided at the upper end of the limiting plate 31, a clamping mechanism 33 is fixedly installed on the left and right groove walls of the limiting groove 32, a sliding groove 34 is provided on the front and rear groove walls of the limiting groove 32, and the clamping mechanism 33 includes a cylinder 331, a clamping plate 332 is fixedly installed on the output end of the cylinder 331, a clamping pad 333 is fixedly connected to the right end of the clamping plate 332, a slider 334 is fixedly connected to the front and rear ends of the clamping plate 332, the cylinder 331 is fixedly installed on the left groove wall of the limiting groove 32, the lower end of the clamping plate 332 does not contact the lower groove wall of the limiting groove 32, the clamping pad 333 is made of rubber, and the two sliders 334 are slidably connected to the two sliding grooves 34 respectively.
[0032] Through the above scheme: the two clamping plates 332 move relative to each other under the push of the cylinder 331, so that the two clamping pads 333 are in close contact with the printed object, so that the printed object can be limited and fixed, and the printed object can maintain a stable position during printing, avoiding problems such as shaking or shifting that cause blurred patterns, thereby ensuring the clarity and accuracy of the pattern.
[0033] In this embodiment, the drying mechanism 7 includes a hot air blower 71, and an air inlet pipe 72 is fixedly installed at the output end of the hot air blower 71. The lower end of the air inlet pipe 72 is fixedly connected to an air collecting box 73, and the left and right outer surfaces of the air collecting box 73 are fixedly connected to diverter pipes 74, and the two diverter pipes 74 are fixedly connected to connecting pipes 75 at the ends away from the air collecting box 73. The front and rear ends of the two connecting pipes 75 are fixedly connected to air outlet pipes 76, and the outer surfaces of the four air outlet pipes 76 are provided with a plurality of air outlets 77. The hot air blower 71 is fixedly installed at the upper end of the drying box 6, and the upper end of the air collecting box 73 is fixedly connected to the upper wall of the drying box 6, and the air collecting box 73 is connected to the inside of the four air outlet pipes 76 through two diverter pipes 74 and two connecting pipes 75. The four air outlet pipes 76 are respectively located at the four corners inside the drying box 6, and the plurality of air outlets 77 are evenly distributed up and down.
[0034] Through the above scheme: the hot air is transported to the air collecting box 73 through the hot air blower 71 through the air inlet pipe 72, and the air collecting box 73 is connected with the four air outlet pipes 76 through two branch pipes 74 and two connecting pipes 75, so that the hot air can be smoothly delivered into the drying box 6 from the several air outlets 77 on the four air outlet pipes 76. Since the four air outlet pipes 76 are located at the four corners of the drying box 6 and the several air outlets 77 are distributed at equal distances up and down, the hot air can be evenly distributed inside the drying box 6, so that the printed objects after silk-screen printing can be heated evenly.
[0035] It should be noted that the utility model is an automatic screen printer. During use, the printed object is placed in the limiting groove 32, and then the two cylinders 331 are started. The two cylinders 331 will drive the two clamping plates 332 to move relative to each other. During the movement, the clamping pads 333 on the clamping plates 332 will fit tightly against the printed object to ensure that the printed object is firmly fixed on the limiting plates 31. Once the printed object is fixed, the conveyor belt 2 will start working to smoothly transport the printed object to the bottom of the printing device 4. During the transmission process, the proximity switch 5 will monitor the position of the printed object and control the start and stop of the conveyor belt 2 to ensure that the printed object accurately stays below the printing device 4, which is convenient for printing operations. After printing is completed, the conveyor belt 2 is turned on and the printing plate 332 is turned on. The conveyor belt 2 will start again to send the printed items to the inside of the drying box 6, and the hot air blower 71 will be started. The hot air will be sent into the air collecting box 73 through the air inlet pipe 72. The hot air in the air collecting box 73 will then pass through two branch pipes 74 and two connecting pipes 75 and be evenly distributed to four air outlet pipes 76. Since the four air outlet pipes 76 are respectively located at the four corners of the drying box 6, and each air outlet pipe 76 is provided with a number of air outlets 77, which are distributed at equal distances up and down, the hot air can be evenly blown into the drying box 6 to ensure that the ink can be quickly solidified and the production efficiency is improved. At the same time, this uniform heating method also helps the ink to better adhere to the printed items, prevents the ink from falling off or peeling, and ensures the stability of the printing quality.
