Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but only represents the selected embodiments of the present application.

[0025] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be an electrical connection; it can be a hydraulic oil circuit connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] See also Figures 1 to 6 The support plate 3 is connected to the printing plate by the support plate 4, and the support plate 4 is connected to the printing plate by the support plate 4.

[0027] The above-mentioned screen positioning seat 3 includes a circular frame 6, the corner end of the circular frame 6 is connected to the upper end of the corner end support arm 2, and the printing screen can be placed on the circular frame 6. At this time, the screen part on the printing screen is not blocked below. An ear plate 7 is fixed on the circular frame 6, and a locking screw 8 passes through the ear plate 7. The inner end of the locking screw 8 is connected to a clamping plate 9. The ear plate 7 and the locking screw 8 form a locking assembly;

[0028] The locking components are located on both sides of the printing screen, so that after the locking screw 8 is rotated, the clamping plate 9 can be controlled to be in close contact with the printing screen, and the printing screen is clamped by the locking components.

[0029] After the screen positioning seat 3 is controlled to move downward until the printing screen is in contact with the carrier and printing is completed, the screen positioning seat 3 needs to be reset so that the carrier can be moved out from the bottom of the screen positioning seat 3. A through hole 10 and a vertical through hole 11 are provided on the screen positioning seat 3. The upper end of the corner support arm 2 passes through the through hole 10. A flat tray 12 is fixed on the corner support arm 2. The setting of the flat tray 12 limits the maximum displacement of the carrier support plate 4 moving upward. A first compression reset spring 13 is provided above the flat tray 12. The first compression reset spring 13 is sleeved on the corner support arm 2, and the screen positioning seat 3 is located above the first compression reset spring 13.

[0030] When the screen positioning seat 3 moves downward, a downward pushing force is applied to the first compression return spring 13, so that the first compression return spring 13 is compressed. In this way, after printing is completed, no pressure is applied to the screen positioning seat 3, and the screen positioning seat 3 can be reset under the action of the restoring force of the first compression return spring 13.

[0031] In order to increase the applicability and realize printing on carriers of different thicknesses, an adjusting rod 14 is fixed on the corner support arm 2. The adjusting rod 14 is parallel to the corner support arm 2, and the adjusting rod 14 passes through the vertical through hole 11, and an adjusting disk 15 is screwed on the adjusting rod 14. Through the setting of the adjusting disk 15, the maximum displacement of the screen positioning seat 3 when moving downward is limited. Since the adjusting disk 15 is screwed to the adjusting rod 14, the horizontal height can be changed after the adjusting disk 15 is rotated, thereby changing the distance that the screen positioning seat 3 can move downward, which can be suitable for carriers of different thicknesses.

[0032] Since there is a pattern to be printed on a part of the printing screen, in order to accurately control the corresponding position of the pattern on the carrier and avoid putting too much dye in the area without the pattern, a calibration component is arranged on the placing base 1, and the calibration component is connected to the placing base 1 by a sliding connection structure, so that the calibration component can slide on the placing base 1, thereby adjusting the position of the calibration component;

[0033] The calibration component specifically includes two sliding arms 16, the carrier support plate 4 and the screen positioning seat 3 are both located between the two sliding arms 16, a slide groove is provided on the placement base 1, and a slide seat matched in the slide groove is provided at the lower end of the sliding arm 16, the cross section of the slide groove is a "convex" shape, a threaded hole is provided on the placement base 1, and the threaded hole extends downward from the top surface of the placement base 1 to communicate with the slide groove. After the sliding arm 16 is moved to the specified position, a threaded push rod can be screwed into the threaded hole so that the threaded push rod and the slide seat are abutted to achieve position locking of the sliding arm 16. A position indicating rod 17 and a calibration rod 18 are provided between the two sliding arms 16, and the position indicating rod 17 and the calibration rod 18 The positioning rod 18 is arranged vertically, that is, the horizontal height of the positioning rod 17 is greater than the horizontal height of the calibration rod 18. At this time, the positioning rod 17 is located above the screen positioning seat 3, and the calibration rod 18 is located between the carrier support plate 4 and the screen positioning seat 3. When moving the calibration component, the positioning rod 17 can be moved to the edge of the pattern on the printing screen, and then the horizontal distance between the calibration rod 18 and the positioning rod 17 can be adjusted. In this way, the distance between the edge of the pattern on the carrier and a certain edge on the carrier is obtained. After replacing the carrier, it is only necessary for the corresponding edge of each carrier to be against the calibration rod 18 during the printing process, so that the position of the pattern formed on this carrier can remain unchanged.

[0034] After the position of the indicating rod 17 is adjusted, the position of the calibration rod 18 needs to be adjusted. A slide 19 is fixed at the end of the calibration rod 18. The slide 19 is connected to the sliding arm 16 through a measuring assembly. A slide hole 20 is provided on the slide 19. The measuring assembly passes through the slide hole 20. The measuring assembly is in a horizontally extended state. The measuring assembly is connected to a vertical sleeve 21 mounted on the sliding arm 16. The vertical sleeve 21 can move along the length direction of the sliding arm 16. A limiting short rod 22 is fixed on the vertical sleeve 21. The limiting short rod 22 is matched with a limiting slide 23 provided on the carrier tray 4, so that the sliding arm 16 can move along the direction of the carrier tray 4, and in the process of the lifting mechanism 5 controlling the carrier tray 4 to move upward, the calibration rod 18 can be driven to move upward accordingly.

[0035] It should be noted that the measuring assembly includes a measuring rod 24 and a rail rod 25. The measuring rod 24 has a scale, and the rail rod 25 serves as a guide rail for limiting the horizontal movement of the calibration rod 18. The measuring rod 24 is parallel to the rail rod 25, and both the measuring rod 24 and the rail rod 25 are passed through by a slide 19. A sliding plate 26 is fixed to the same side end of the measuring rod 24 and the rail rod 25. The extending directions of the measuring rod 24 and the rail rod 25 are perpendicular to the sliding arm 16. The sliding plate 26 is connected to the vertical sleeve 21. When adjusting the horizontal distance between the calibration rod 18 and the position display rod 17, an external thread is provided on the rail rod 25, and a regulating disk 27 is screwed through the external thread. The slide 19 is located between the regulating disk 27 and the sliding arm 16 A second compression return spring 28 is sleeved on the rail rod 25, and the second compression return spring 28 is located between the slide 19 and the sliding arm 16. At this time, rotating the regulating disk 27 can make the slide 19 move horizontally. When the horizontal distance between the calibration rod 18 and the position indicating rod 17 is reduced, the second compression return spring 28 is compressed. When the horizontal distance between the calibration rod 18 and the position indicating rod 17 reaches the maximum, the second compression return spring 28 is restored to an uncompressed state. Regardless of the state of the second compression return spring 28, the carrier can be placed on the carrier support plate 4, and when the carrier applies a thrust to the calibration rod 18, the regulating disk 27 blocks the calibration rod 18.

[0036] Although the sliding plate 26 moves with the calibration rod 18, the vertical sleeve 21 does not move in the horizontal direction at this time. The connection structure between the sliding plate 26 and the vertical sleeve 21 is as follows:

[0037] A locking hole is provided on the sliding plate 26, and the sliding plate 26 is located on the outside of the sliding vertical arm 16, that is, the sliding vertical arm 16 and the vertical sleeve 21 are both located between the sliding plate 26 and the carrier support plate 4. At this time, a guide plate 29 is fixed on the vertical sleeve 21, and the guide plate 29 and the carrier support plate 4 are located on the same horizontal plane. The extension direction of the guide plate 29 is the same as the extension direction of the measuring component, and a guide strip opening 30 is provided on the guide plate 29, and a locking rod 31 passes through the guide strip opening 30, and the locking rod 31 passes through the sliding plate 26 at the same time. An inner chuck is fixed at the inner end of the locking rod 31, and the inner chuck is located between the guide plate 29 and the carrier support plate 4. A locking disk 32 is screwed on the locking rod 31, and the guide plate 29 and the sliding disk 26 are both located between the locking disk 32 and the guide plate 29, forming a connection between the locking rod 31 and the sliding disk 26. When the horizontal position of the locking rod 31 needs to be adjusted, the sliding disk 26 can slide along the length direction of the guide strip mouth 30. After the position adjustment is completed, the position of the calibration rod 18 can be locked by tightening the locking disk 32.

[0038] In addition, the lifting mechanism used in the present application may be an electric push rod or a hydraulic cylinder. When the lifting mechanism is extended or shortened, the vertical movement of the carrier pallet 4 may be controlled.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
