[0075] Furthermore, the L-shaped plate 921 is rotatably installed in the frame 1 and rotatably cooperates with the annular groove 72 through a rotating shaft; wherein the top end of the L-shaped plate 921 is transmission-connected to the printing table 51 through a rotating shaft 922, and the bottom end is transmission-connected to the screen frame 52 through a connecting rod assembly 923.

[0076] Furthermore, the rotating plate 924 is rotatably installed in the frame 1 via the connecting shaft 925; the connecting rod 926, both ends of which rotatably connect the rotating plate 924 and the L-shaped plate 921; the mounting plate 927 is installed on the connecting shaft 925; wherein the mounting plate 927 is rotatably connected to the mesh frame 52 via the adjusting component 928.

[0077] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the rotating unit 7 includes a disk body 71, a rotating shaft 73 and an annular groove 72 arranged on the surface of the disk body 71; the transmission unit 8 includes a servo motor 81, a chain 1 82 and a chain 2 83; the rotating unit 7 is provided with two parts, the output end of the servo motor 81 and one of the rotating shafts 73 are connected by the chain 1 82, and the two rotating shafts 73 are connected by the chain 2 83. Through the arrangement of the chain 1 82 and the chain 2 83, the rotating shaft 73 is driven to rotate synchronously, and the rotating unit 7 is driven to rotate synchronously at the same time; the two rotating units 7 are respectively connected to the transmission frame 91 and the linkage frame 92, and the rotation of the rotating unit 7 drives the transmission frame 91 and the linkage frame 92 to rotate synchronously; the transmission frame 91 and the linkage frame 92 are respectively connected to the tooth bar 3 and the printing unit 5, and the rotation of the transmission frame 91 and the linkage frame 92 realizes the opening and closing of the tooth bar 3 and the printing unit 5, so as to realize the loading and printing of the material.

[0078] The transmission frame 91 and the linkage frame 92 cooperate with the annular groove 72 via the rotating shaft, and a roller is rotatably mounted on the top of the rotating shaft to reduce the friction between the rotating shaft and the annular groove 72 .

[0079] There are several lower teeth 32, which are fixedly installed on the side of the support plate 31, and there are several upper teeth 34, which are rotatably installed in the support plate 31 and are located above the lower teeth 32, corresponding to the positions of the lower teeth 32 one by one; the middle part of the upper teeth 34 is arc-shaped, and the two ends are flat, which is convenient for the installation of the upper teeth 34. At the same time, the top ends of the upper teeth 34 and the lower teeth 32 are slightly wider, which is used to increase the friction with the material and facilitate the clamping of the material; one end of the fixed block 33 extends outward for fixedly installing the spring 37, and the two ends of the spring 37 are fixedly connected to the fixed block 33 and the support plate 31.

[0080] The disk body 71 connected to the push plate 911 rotates counterclockwise in the frame 1 through the rotating shaft. When the top of the push plate 911 rotates to the top, the lowest point of the arc surface 912 abuts against the protrusion 36. Then, the push plate 911 continues to rotate, and the protrusion 36 slides on the arc surface 912. At the same time, the push plate 911 pushes the protrusion 36 upward. The movement of the protrusion 36 drives the movable shaft 35 to rotate, and the movable shaft 35 drives the fixed block 33 to rotate. 33 drives the upper tooth mouth 34 to rotate, and at the same time squeezes the spring 37 set on the side, the spring 37 is deformed, and the tooth mouth on the tooth row 3 is opened, and the end of the material is transmitted to between the upper tooth mouth 34 and the lower tooth mouth 32; after the protrusion 36 finishes sliding on the arc surface 912, the protrusion 36 and the upper tooth mouth 34 lose resistance, and the spring 37 pushes the fixed block 33 back to its original position, and the fixed block 33 drives the upper tooth mouth 34 and the lower tooth mouth 32 to close, and fixes and clamps the material.

[0081] After the gripper bar 3 takes the material, the driving device 4 drives the gripper bar 3 to move toward the printing unit 5 .

[0082] A plurality of vertical sliding devices are provided between the printing table 51, the screen frame 52 and the frame 1, so that the movement of the printing table 51 and the screen frame is a vertical reciprocating motion; the disk body 71 connected to the L-shaped plate 921 drives the L-shaped plate 921 to rotate counterclockwise in the frame 1, and its top end drives the printing table 51 to rotate counterclockwise through the rotating shaft 922, that is, the printing table 51 moves downward, and at the same time, the bottom end of the L-shaped plate 921 drives the connecting shaft 925 to rotate counterclockwise through the connecting rod 926 and the rotating plate 924, and the connecting shaft 925 drives the mounting plate 927 to rotate, and the top end of the mounting plate 927 is located on the side of the connecting shaft 925 away from the disk body 71. When the mounting plate 927 rotates, its top end gradually rises, driving the screen frame 52 to move upward. At this time, the printing unit 5 is opened, and the tooth row 3 moves to between the printing table 51 and the screen frame 52.

[0083] Since the annular groove 72 on the surface of the disk body 71 is of eccentric non-circular design, when the shaft rotates to a certain position in the annular groove 72, the annular groove 72 pushes the L-shaped plate 921 to rotate clockwise through the shaft. Similarly, the printing table 51 and the screen frame 52 can be moved closer to each other, making it convenient for the printing unit 5 to print the material.

[0084] After the printing is finished, the printing unit 5 is opened again, and the driving device 4 drives the gripper row 3 to move away from the printing unit 5, and at the same time, the adjacent gripper row 3 is conveyed into the printing unit 5 for printing.

[0085] The driving device 4 drives the tooth row 3 to move to the tail end of the conveyor belt 2, and collides with the protrusion 36 on the tooth row 3 through the ejector pin fixed at the tail, pushing the protrusion 36 upward, and at the same time, the protrusion 36 drives the movable shaft 35 and the upper tooth mouth 34 to rotate, so that the material is separated from the fixation of the tooth row 3, and the material falls onto the conveyor belt 2. The spring 37 drives the upper tooth mouth 34 back to its original position, and at the same time, the conveyor belt 2 transmits the material to the next piece.

[0086] The driving device 4 drives the separated gripper row 3 back to the loading position for loading, thereby realizing the cyclic loading of the equipment.

[0087] Embodiment 3:

[0088] like Figures 1 to 7 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the adjusting component 928 is also included as a cylinder 10; wherein the output end of the cylinder 10 is rotatably connected to the mesh frame 52, and the bottom end is rotatably connected to the mounting plate 927.

[0089] In this embodiment of the present application, due to the adoption of the above-mentioned structure, a limit unit is fixedly provided at the bottom of the cylinder 10 to prevent the cylinder 10 from exceeding its working range; the output end of the cylinder 10 is rotatably connected to the mesh frame 52, and the mesh frame 52 can be pushed upward or downward through the output end of the cylinder 10.

[0090] The cylinder 10 drives the screen frame 52 to move upward. When the printing unit 5 is closed, the distance between the printing table 51 and the screen frame 52 increases, and materials with thicker thickness can be printed. The cylinder 10 drives the screen frame 52 to move downward. When the printing unit 5 is closed, the distance between the printing table 51 and the screen frame 52 decreases, and materials with thinner thickness can be printed. By setting the cylinder 10, the height of the screen frame 52 relative to the printing table 51 is changed, so as to change the distance between the screen frame 52 and the printing table 51 when closed, so as to facilitate the printing unit 5 to print materials of different thicknesses, improve the practicability of the equipment, and at the same time improve the printing effect of the printing unit 5 on the material.
