Detailed implementation manners

[0024] Example 1, see the attached Figure 2-3, 5 - 8, A direct injection platform for a two - way printing machine, comprising a bearing platform arranged on a moving bracket. The bearing platform includes an L - shaped support 1, a lifting mechanism 3, and a bearing plate 2; The lifting mechanism includes a support sleeve 31 fixedly sleeved in a socket hole 32 at the end of the L - shaped support, and a lifting handle 34. A setscrew 394 is provided between the lower ends of the socket hole 32 and the support sleeve 31 to fix the support sleeve 31 in the socket hole 32. A lifting shaft 33 is slidably sleeved in the support sleeve 31. On the side surface of the disc body 341 of the lifting handle 34, there is a grip 342. The disc body 341 is rotatably sleeved at the upper end of the support sleeve 31. The annular upper surface of the disc body 341 is provided with at least three arc - shaped steps 343. The edge part of the step body in the arc - shaped step is provided with a limiting boss 346. The height difference between the lower end and the upper end of the arc - shaped step 343 is the height adjustment range of the bearing plate 2. The upper end of the lifting shaft 33 is fixedly connected with a support plate 35, and the bearing platform is fixedly connected above the support plate. On the bottom surface of the support plate 35, there are round - head cylindrical pins 36 with the same number and corresponding positions as the arc - shaped steps 343. The round head at the lower end of the round - head cylindrical pin presses on the surface of the arc - shaped step 343; Along the generatrix direction of the side surface of the lifting shaft 33, there is a guide groove 331. On the side surface of the support sleeve 31, there are a number of through - holes 311 corresponding to the positions. A guide pin 37 is threadedly connected in the through - hole. The guide pin and the guide groove 331 provide sliding guidance for the lifting shaft 33 to move its axis and avoid the phenomenon of rotational misalignment.

[0025] On the upper end of the outer side surface of the support sleeve 31, there is an annular groove 312. On the inner side surface of the disc body 341 of the lifting handle 34, there are a number of elastic hook bodies 344 evenly distributed. The elastic hook bodies 344 are hooked into the annular groove 312 and can slide relatively. The lifting handle 34 is rotationally connected to the upper end of the support sleeve 31 through the elastic hook bodies and the annular groove to avoid the movement of its axis.

[0026] On the outer side surface of the disc body 341, there is a baffle 345. On the upper surface of the L - shaped support 1, there is a limiting post 38 corresponding to the position of the baffle 345. When the baffle 345 and the limiting post 38 are in contact, the lifting handle 34 rotates to the limit, and the bearing plate 2 rises to the highest position.

[0027] On the upper surface of the L - shaped support 1, there is a U - shaped guide plate 391. Vertically provided on the bottom surface of the support plate 35 is a guide post 392 with the lower end sleeved in the U - shaped guide plate. The U - shaped guide plate 391 and the guide post 392 further provide lifting guidance for the bearing plate 2 to avoid the phenomenon of deviation caused by circumferential rotation.

[0028] A support ring 393 is sleeved on the support sleeve 31 between the disc body 341 and the L - shaped support 1. The upper surface of the support ring 393 and the bottom surface of the disc body 341 are sliding surfaces. The support ring rotates and supports on the bottom surface of the disc body 341 to improve its pushing and supporting force on the round - head cylindrical pin 36 and the bearing plate 2.

[0029] The L-shaped support 1 is provided with a receiving seat plate 51 that covers the bearing plate 2 from below. This receiving seat plate 51 is used to catch the printing material of the accidental pulley and prevent it from falling to the ground or inside the printing machine bracket.

[0030] The height adjustment method of the direct injection platform in this embodiment is as follows: Hold the grip 342 of the lifting handle 34 with the hand and rotate the lifting handle clockwise. The arc-shaped step 343 inside the disc body 341 rotates accordingly and pushes the round head cylindrical pin 36 upward. The round head cylindrical pin jacks up the bearing plate 2, and the lifting shaft 33 connected to the bottom surface of the bearing plate 2 slides upward in the support sleeve 31 to adjust the height. After the height adjustment is in place, the round head cylindrical pin 36 supports on the surface of one of the step bodies in the arc-shaped step 343, and the limit boss 346 blocks the end of the round head cylindrical pin 36 on the outside to keep it in a stable state, and the bearing plate 2 is in a stable state. During the height adjustment process, the guide groove 331 moves along the guide pin 37 to provide axial sliding guidance for the lifting shaft 33 and prevent the phenomenon that the bearing plate 2 is misaligned due to rotation.

[0031] Embodiment 2, see the appendix Figure 1-4 On the basis of Embodiment 1, in this embodiment, the moving bracket is designed to be provided with two sliding rods 42 between the two ends of its frame body 41. The lower end of the L-shaped support 1 is provided with a bottom support slider 43, and both sides of the bottom support slider are provided with sliding sleeves 431 slidably connected to the sliding rods 42. The L-shaped support 1 can freely slide along the two sliding rods 42 through the sliding sleeves 431 on both sides. In the middle of one end of the frame body 41, a driving pulley 441 is provided. A motor is arranged on one side of the driving pulley, and a pulley is installed on the output shaft of this motor. This pulley and the driving pulley 441 are connected by a belt. A driven pulley 442 is provided at the other end. The driving pulley 441 and the driven pulley are installed with a belt 45. The middle part of this belt is fixedly connected to the middle part of the bottom support slider 43 through a pressing plate 46. The bottom support slider 43 is pulled by the belt 45 to slide on the two sliding rods 42, so as to realize the reciprocating movement of the bearing plate 2 with the moving bracket for printing or retracting and resetting operations.

[0032] And a protective cover 411 is installed at the outer end of the moving bracket to protect the internal driving mechanism through this protective cover and play a role in dust prevention.

[0033] An auxiliary bracket 47 is provided on the side surface of the bottom support slider 43. The lower end of this auxiliary bracket is provided with an auxiliary roller 471 supported on the bottom plate of the frame body 41. The auxiliary bracket 47 provides auxiliary support for the bottom support slider 43 at the side through the roller to improve the stability of its movement; a limit plate 472 is provided at the end of the auxiliary bracket 47, and a photoelectric switch 48 is correspondingly provided at the end of the frame body 41. When the limit plate 472 enters the photoelectric switch 48, it triggers the photoelectric switch 48 to play a role in limiting the movement of the platform and prevent collision phenomena.
