[0002] Screen printing refers to using a screen as a base to make a screen printing plate with images and texts through photosensitive plate making. Generally, the workpiece is positioned first, and then moved to the printing station for screen printing. Before screen printing, in order to ensure the printing quality, the workpiece often needs to be cleaned and dusted, because a dust removal station needs to be added between the positioning station and the printing station, but this increases the equipment cost and floor space. At the same time, the increase in processes leads to an increase in the daily maintenance cost of the equipment and a decrease in stability.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] See also Figures 1 to 3 The utility model provides a new shuttle structure for a screen printing machine, which is used in a screen printing machine. A new shuttle structure for a screen printing machine includes a guide rail main frame 1 and a bearing seat 6. A linear guide rail 2 is arranged at the upper end of the guide rail main frame 1, and a shuttle bar 4 is arranged on the linear guide rail 2. The shuttle bar 4 on the linear guide rail 2 is arranged in two groups. The upper ends of the linear guide rail 2 are respectively provided with limit modules 3. One end of the guide rail main frame 1 is also provided with a driving component 5. A shuttle lifting guide device 8 is arranged at the lower end of the guide rail main frame 1. A bearing seat 6 is arranged at the lower end of the shuttle lifting guide device 8. A multi-link synchronous lifting device 7 is arranged at the upper end of the bearing seat 6. The bearing seat 6 provides an overall support force for the device. The shuttle bar 4 is arranged in two groups, moves back and forth on the linear guide rail 2, and is stably limited by the limit module 3. At the same time, the multi-link synchronous lifting device 7 can drive the guide rail main frame 1 to rise and fall through the driving component 5. The shuttle lifting guide device 8 can be used as a guide when the device rises or falls, and enhances the stability when rising or falling.

[0025] The device is started when in use. Since the device is usually arranged in the overall assembly line of the screen printing machine, when the product is transmitted to the shuttle device of the present application, the device first lifts the entire device to the position where the conveyor belt receives it through the multi-link synchronous lifting device 7, and then descends through the synchronous lifting device after receiving it, and transports the product to the next stage through the shuttle bar 4. The two shuttle bars 4 transmit and stop at the limit at the same time, realizing the shuttle structure of the screen printing machine with dual workstations working simultaneously.

[0026] Furthermore, a deflection device 9 is provided in the middle of the bearing seat 6, and the bearing seat 6 is connected to the connecting rod synchronous lifting device through the deflection device 9. The deflection device 9 converts the horizontal or vertical force from the driving component 5 into the required force in a specific direction, and can evenly and effectively transfer the energy from the power source to the entire device, ensuring the consistency of speed and pressure during the lifting process, while also absorbing and alleviating part of the vibration generated by the dynamic operation, and maintaining stability during the lifting process.

[0027] Furthermore, the driving assembly 5 includes a synchronous rotation assembly 54 arranged at the upper end of the guide rail main frame 1 for controlling the movement of the shuttle bar 4, a first driving motor 51 arranged at the bottom of the guide rail main frame 1 and connected to the multi-link synchronous lifting device 7, and a second driving motor 52 for driving the synchronous rotation assembly 54, and a synchronous belt 53 is arranged at one end of the second driving motor 52, and the synchronous rotation assembly 54 on the guide rail main frame 1 is driven by the synchronous belt 53. The first driving motor 51 connected to the multi-link synchronous lifting device 7 is mainly responsible for driving the lifting device, thereby realizing the up and down lifting of the device as a whole. It can ensure that the distance between the platform and the screen is constant during printing, thereby maintaining the consistency of printing pressure and effect. The second driving motor 52 drives the synchronous rotation assembly 54 on the guide rail main frame 1 through the synchronous belt 53 to control the movement of the shuttle bar 4, ensuring the effective transmission of mechanical power and reducing energy loss.

[0028] Furthermore, an L-shaped fixing seat 55 for providing support is provided on the first drive motor 51. Due to its unique shape, the L-shaped fixing seat 55 can provide more stable support, help reduce vibration and noise during motor operation, and simplify the assembly process, making the installation of the drive assembly 5 more convenient.

[0029] Furthermore, a sensor 81 for detection and signal feedback is also provided on one side of the shuttle lifting guide device 8. The sensor 81 can monitor the operating status of the equipment in real time, such as pressure, speed, etc., and feed back the data to the control system for adjustment and optimization, which greatly improves the stability and repeatability of the use process.

[0030] The limit module 3 is an electromagnet adsorption limit, which provides an efficient and reliable positioning method. The electromagnetic force quickly and accurately adsorbs or releases the limit components, greatly reducing mechanical wear and improving the accuracy of the operation.

[0031] The multi-link synchronous lifting device 7 is a combined setting with adjustable length, and the bearing seat 6 and the shuttle lifting guide device 8 are both provided with multiple groups corresponding to the multi-link synchronous lifting device 7. Since the multi-link synchronous lifting device 7 is a setting with adjustable length, the corresponding length is set according to the length of the guide rail, thus providing great flexibility for different types of printing operations, allowing the operator to adjust the length and height of the device according to different printing requirements, which not only improves the applicability of the equipment, but also increases the flexibility of production efficiency and quality control.

[0032] The utility model provides a new shuttle structure for a screen printing machine, which has the following advantages:

[0033] 1. By setting up two shuttle bars, double-station transportation can be achieved simultaneously, effectively increasing work efficiency.

[0034] 2. The shuttle lifting guide rod and the deflection device can enhance the stability when ascending or descending.

[0035] 3. Fully automatic operation, no manual operation required, the machine is built into the automatic production line of silk screen printing, effectively reducing manpower.

[0036] 4. The overall length of the device is adjustable, which improves the applicability of the equipment and increases the flexibility of production efficiency and quality control. The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
