Description

Technical Field

[0001] The utility model relates to the field of screen printing machines, in particular to a screen printing machine with a drying device. Background Art

[0002] The screen printing machine mainly includes ink, a scraper assembly, a screen printing plate and a printing table. The substrate passes under the screen. The screen printing plate with the image part can pass the ink, while the mesh without the image part is not permeable to the ink. The scraper squeezes the ink through the image part onto the substrate. In the Chinese utility model patent with the announcement number CN206351585U, a screen printing machine is disclosed. When the substrate is fed, a reeling mechanism and a reeling mechanism are respectively arranged on the left and right sides of the frame. The reeling mechanism enables the rolled substrate to be unfolded and transported under the screen for printing. After printing, it is reeled and collected on the reeling mechanism. The ink on the surface of the substrate is not completely dried just after printing. Reeling it up or making it go through the next process will cause the ink on its surface to be scratched or even bonded. For this reason, we designed a screen printing machine with a drying device. Utility Model Content

[0003] In order to solve the technical problem that the ink is not completely dried and the ink on its surface may be scratched when it is rolled up or subjected to the next process, the utility model provides a screen printing machine with a drying device.

[0004] The utility model is implemented by the following technical scheme: a screen printing machine with a drying device, comprising a machine platform, an extension frame is arranged on the left side of the machine platform, and a movable frame plate is arranged in the extension frame for sliding left and right, a clamping cylinder is arranged on the movable frame plate, and two locking plates are arranged on the leftmost end of the extension frame, side plates are respectively installed on the front and rear sides of the outside of the extension frame, and a right plate and a left plate are respectively installed on the left and right sides of the extension frame, a bottom plate is also arranged at the bottom end of the extension frame, an upper baffle member is arranged above the extension frame, and a plurality of upper air pipes and lower air pipes distributed at equal intervals are respectively arranged on the upper and lower ends of the left and right sides of the two extension frames, a plurality of linearly distributed exhaust holes 2 are opened on the lower surface of the upper air pipe, and a plurality of linearly distributed exhaust holes 1 are opened on the upper surface of the lower air pipe.

[0005] As a further improvement of the above scheme, the left ends of the upper air duct and the lower air duct are placed on the left side of the extension frame, and the left ends of the upper air duct and the lower air duct are connected to the air intake main pipe, and the air intake main pipe is connected to the air outlet of an external hot air blower through a hose. Airflow with a certain temperature can enter the upper air duct and the lower air duct, and be blown to the upper and lower surfaces of the substrate through exhaust hole two and exhaust hole one, respectively, thereby accelerating its drying efficiency.

[0006] As a further improvement of the above scheme, parts of the lower ends of the left and right plates are cut away to form movable notches, and the height of the movable notch is placed 2-3 cm above the printing table on the machine, and the width of the movable notch is greater than the maximum width of the screen plate on the machine. The left and right plates can ensure that the internal temperature is maintained within a certain degree, and the design of the movable notch also facilitates the movement of the substrate into the interior for drying operations.

[0007] As a further improvement of the above solution, two symmetrically distributed penetration holes are opened on the left side plate, and the two penetration holes are respectively designed to correspond to the two locking plates. The design of the penetration holes facilitates the up and down movement of the locking plates without causing interference therewith.

[0008] As a further improvement of the above scheme, the lower air pipe is located below the bottom end of the movable frame plate on the extension frame, and a plurality of evenly distributed through-holes are formed on the left and right sides of the movable frame plate on the extension frame, and the plurality of upper air pipes slide through the corresponding through-holes. The movable frame plate will not affect the upper air pipes when moving, thereby facilitating the normal movement of the movable frame plate.

[0009] As a further improvement of the above scheme, the upper baffle member includes a rubber plate 1 and a rubber plate 2, the rubber plate 1 and the rubber plate 2 are respectively connected to the left and right sides of the movable frame plate, and the ends of the rubber plate 1 and the rubber plate 2 away from the movable frame plate are respectively connected to the left and right sides of the extension frame, and the upper baffle member can form a complete space with the side plate, the left plate, the right plate and the bottom plate, so that the internal temperature is maintained within a certain range, thereby ensuring the drying effect;

[0010] The rubber sheet 1 and the rubber sheet 2 are both designed in a corrugated shape. The rubber sheet 1 and the rubber sheet 2 can be unfolded or folded as the movable frame plate moves left and right, so that the top of the extension rack can always be shielded, so that the internal airflow and temperature are not easy to spread outward, thereby ensuring the drying efficiency.

[0012] 1. The utility model forms a complete space with the upper baffle plate, the side plate, the left plate, the right plate and the bottom plate, and the upper and lower sides of the space are respectively provided with an upper air duct and a lower air duct, so that airflow with a certain temperature can be blown to the upper and lower surfaces of the substrate, so that the airflow flowing on the surface of the substrate and the temperature borne by the substrate are more uniform, thereby allowing the ink on the substrate to be dried quickly;

[0013] 2. By dividing the upper baffle into rubber plate 1 and rubber plate 2, both of which are designed in a corrugated shape, rubber plate 1 and rubber plate 2 can be unfolded or folded as the movable frame plate moves left and right, so that the top of the extension rack can always be in a shielded state, making it difficult for the internal airflow and temperature to spread outward, thereby ensuring the drying efficiency.

Air flow with a certain temperature can enter the upper air duct 8 and the lower air duct 7, and be blown to the upper and lower surfaces of the substrate through the exhaust hole 2 and the exhaust hole 1 71 respectively, thereby accelerating its drying efficiency.

[0023] Part of the lower ends of the left plate 6 and the right plate 5 are cut away to form a movable notch 61, and the height of the movable notch 61 is placed 2-3 cm above the printing table on the machine 1, and the width of the movable notch 61 is greater than the maximum width of the screen plate on the machine 1. The left plate 6 and the right plate 5 can ensure that the internal temperature is maintained within a certain degree, and the design of the movable notch 61 also facilitates the movement of the printed material into the interior for drying.

[0024] The left side plate 6 is provided with two symmetrically distributed penetration holes 62 , and the two penetration holes 62 are respectively designed to correspond to the two locking plates. The design of the penetration holes 62 facilitates the upward and downward movement of the locking plates without causing interference therewith.

The movable frame plate will not be affected by the upper air pipes 8 when moving, thereby facilitating the normal movement of the movable frame plate.

[0026] The upper baffle member 4 includes a rubber plate 1 41 and a rubber plate 2 42, which are respectively connected to the left and right sides of the movable frame plate, and the ends of the rubber plate 1 41 and the rubber plate 2 42 away from the movable frame plate are respectively connected to the left and right sides of the extension frame 2, and the upper baffle member 4 can form a complete space with the side plate 3, the left side plate 6, the right side plate 5 and the bottom plate 63, so that the internal temperature is maintained within a certain range, thereby ensuring the drying effect;
