[0023] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual Figures 1 to 5 A screen printing machine with an adjustable workbench includes a frame 1, a printing mechanism 2 is provided on the frame 1, the printing mechanism 2 includes two screen frame clamps 22, the same printing screen frame a is placed on the two screen frame clamps 22, and a printing scraper 23 is slidably arranged between the two screen frame clamps 22; a feeding mechanism 3 is provided on the frame 1, the feeding mechanism 3 includes a mounting frame 31, and a conveyor belt 1 32 and a conveyor belt 2 33 are arranged on the mounting frame 31 for transmission; a supporting mechanism 4 is provided on the frame 1, the supporting mechanism 4 includes a printing platform 41, the printing platform 41 is slidably arranged on the frame 1, and a plurality of balance adjustment rods 42 are rotatably provided at the bottom of the printing platform 41, and the same crank arm 43 is rotatably provided between the corresponding two balance adjustment rods 42, and a push arm 44 is fixedly provided on the crank arm 43, and the corresponding two push arms 44 are rotatably provided with the same connecting rod 45, and the supporting mechanism 4 includes a power mechanism, which is used to drive the printing platform 41 to move vertically, and a groove is provided on the printing platform 41, and the mounting frame 31 is located in the groove.

[0025] It should be noted that the screen frame clamps 22 are arranged in a U-shaped structure, and the openings of the two screen frame clamps 22 are arranged toward the sides close to each other.

[0026] It should also be noted that two motors are fixedly installed on the mounting frame 31, and four guide rollers are also rotatably installed on the mounting frame 31. Conveyor belt 1 32 and conveyor belt 2 33 are both driven by two corresponding guide rollers, and the output shaft of the motor is fixed to the guide rollers.

[0027] The specific implementation scenario is as follows: drive the two screen frame clamps 22 to approach each other, place the printing screen frame a in the opening of the screen frame clamp 22, and position the printing screen frame a through the screen frame clamp 22. The initial position of the support mechanism 4 is at the bottom of its stroke. The workpiece to be processed is placed on the mounting frame 31, and then the mounting frame 31 is driven to move by the rotation of the guide roller. The workpiece is transferred by the movement of the mounting frame 31. When the workpiece is at the specified position, the printing platform 41 is driven to move vertically upward by the power mechanism. The vertical upward movement of the printing platform 41 causes the mounting frame 31 to be located in the groove. When the printing platform 41 moves upward to a certain extent, the bottom of the workpiece contacts the top of the printing platform 41. At this time, the workpiece is fixed on the top of the printing platform 41, and the workpiece is screen-printed by driving the printing scraper 23 and the printing screen frame a downward. After printing is completed, the printing scraper 23 and the printing screen frame a are driven to move upward and reset, and then the positioning between the printing platform 41 and the workpiece is released, and then the printing platform 41 is driven to move. As the printing platform 41 continues to move downward, the bottom of the workpiece contacts the top of the conveyor belt 2 33 again, and then the conveyor belt 2 33 is driven to move to achieve the effect of automatically removing the workpiece.

[0028] Refer to the instruction manual Figures 4 to 6 In order to facilitate the vertical movement of the printing platform 41, specifically, the power mechanism includes a vertical driving unit 46, and the vertical driving unit 46 includes a rotary driver 462. The rotary driver 462 is fixedly arranged in the frame 1, and a push rod 461 is rotatably arranged on the output shaft of the rotary driver 462. The push rod 461 is rotatably arranged with the crank arm 43.

[0029] It should be noted that the rotary driver 462 is configured as a motor, and a connecting shaft is fixedly mounted on the output shaft of the motor, and the connecting shaft is rotatably mounted between the push rod 461. A guide rod is fixedly mounted on the bottom of the printing platform 41, and the guide rod is slidably mounted on the frame 1. The bottom end of the guide rod is rotatably mounted on the balance adjustment rod 42.

[0030] It should also be noted that when it is necessary to drive the printing platform 41 to move vertically, the rotation driver 462 is started, and the rotation of the output shaft of the rotation driver 462 drives the end of the push rod 461 to rotate, and the rotation of the end of the push rod 461 drives the crank arm 43 to rotate. The rotation of the crank arm 43 then transmits the connecting rod 45 to make the two crank arms 43 rotate synchronously. Since there is a limit for vertical movement between the guide rod and the frame 1, when the crank arm 43 rotates, it drives the balance adjustment rod 42 to adjust the position of the guide rod, thereby achieving the effect of adjusting the vertical movement of the printing platform 41.

[0031] Refer to the instruction manual Figure 6 and Figure 7Different from the above-mentioned embodiment, this embodiment provides another driving source for driving the printing platform 41 to move vertically upward. Specifically, the power mechanism also includes a vertical driving unit 2 47. The vertical driving unit 2 47 includes a linear drive. The linear drive is rotatably set in the frame 1, and the output shaft of the linear drive is rotatably set with the push arm 44.

[0032] It should be noted that the second vertical driving unit 47 is configured as a cylinder, and the output shaft of the cylinder is rotatably configured to rotate with the push arm 44 .

[0033] It should also be noted that when the vertical height of the printing platform 41 needs to be adjusted, the vertical drive unit 2 47 is started, the movement of the output shaft of the vertical drive unit 2 47 pushes the push arm 44, and the rotation of the push arm 44 drives the connecting rod 45 to move. The movement of the connecting rod 45 causes the two crank arms 43 to rotate synchronously, and the rotation of the crank arm 43 drives the balance adjustment rod 42 to rotate to achieve the effect of adjusting the vertical height of the printing platform 41.

[0034] Refer to the instruction manual Figure 1 and Figure 2 In order to facilitate the adjustment of the height of the printing screen frame a, specifically, the printing mechanism 2 also includes a printing beam 21, which is slidably set on the frame 1, and the printing scraper 23 and two screen frame clamps 22 are both slidably set on the printing beam 21, and the printing scraper 23 is located between the two screen frame clamps 22.

[0035] It should be noted that a linear motor is fixedly installed in the frame 1 , and the output shaft of the linear motor is fixedly installed with the printing beam 21 . The movement of the output shaft of the linear motor drives the printing beam 21 to move vertically.

[0036] It should also be noted that a threaded rod is rotatably mounted within the printing beam 21. This rod features two sets of external threads with opposite thread directions and equal pitch. These threads are connected to the threaded rods of the stencil and frame clamps 22. A motor is fixed to the threaded rods. Rotation of the motor's output shaft drives the two stencil and frame clamps 22 to move synchronously in opposite directions. A linear motor is also fixed within the printing beam 21. An auxiliary seat is fixed to the motor's output shaft, and a printing scraper 23 is mounted on the auxiliary seat. The auxiliary seat houses a paint spraying system that works with the printing scraper 23. This is a mature prior art technology and will not be elaborated upon here.

[0037] Refer to the instruction manual Figure 3 and Figure 6 To inspect and maintain the equipment, a rotating frame 34 is rotatably mounted on the mounting frame 31, and an electric push rod is rotatably mounted on the frame 1. The output shaft of the electric push rod is rotatably mounted on the rotating frame 34. Two limit seats 35 are slidably mounted on the mounting frame 31, and the conveyor belt 1 32 is located between the two limit seats 35.

[0038] It should be noted that the electric push rod is configured as a cylinder, and the output shaft of the cylinder is rotatably configured to the conveyor belt 2 33 .

[0039] It should also be noted that when working, the electric push rod pushes up the conveyor belt 2 33 so that the conveyor belt 2 33 is set parallel to the mounting frame 31, and the workpiece is synchronously transmitted to the next process; when not working, the electric push rod lowers the conveyor belt 2 33, reducing the space occupied by the conveyor belt 2 33, making it easier for staff to pass through to inspect and maintain the equipment.

[0040] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
