Description

Technical Field

[0001] The utility model relates to a bottle printing fixture seat for a screen printing machine. Background Art

[0002] In the prior art, the clamping seat on the screen printing machine generally includes a nozzle and a base film. During printing, the material (such as a bottle) is clamped between the nozzle and the base film. However, the current nozzle and the base film are fixed, that is, the distance between the nozzle and the base film is not adjustable. This makes it easy to damage the material during the process of clamping it to the nozzle and the base film.

[0003] The utility model with application number CN201820174020.4 discloses a clamp seat, which describes that when clamping materials, the distance between the nozzle assembly and the bottom film assembly can be increased first by driving the cylinder. After the position of the material is stable, the nozzle assembly and the bottom film assembly are driven by the cylinder to move closer together to clamp the material, thereby avoiding damage to the material. However, the document describes that the installation method for the material, that is, the bottle body, is complicated. Even if it can be adjusted according to the size of the material, due to the complexity of the components, manual operation of the reverse sliding assembly is required for adjustment. In addition, a complex positioning device is also provided on the clamp seat for adjustment to adapt to the assembly of the material, which is not flexible and convenient enough.

[0022] like Figure 1-4 As shown, a bottle printing fixture for a screen printing machine includes a base 1, a cylinder drive group 2 fixedly mounted above one end of the base 1, a guide rail 3 fixedly mounted in the middle of the base 1 by bolts, a first sliding seat 4 assembled at one end of the guide rail 3 and driven to slide by the cylinder drive group 2, a bottle body rotation assembly 5 fixedly mounted on one side above the first sliding seat 4 by bolts, a limit block 6 assembled on the base 1 by bolts and close to the first sliding seat 4, a dust cover 7 fixedly mounted to the base 1 and covering the middle section of the guide rail 3, a second sliding seat 8 assembled at the other end of the guide rail 3 and driven to slide by the cylinder drive group 2, and a bottle body 9 assembled with the second sliding seat 8 through the bottle body rotation assembly 5 and driven to rotate by the bottle body rotation assembly 5.

[0023] The base 1 includes a base body 11, an extension support arm 12 integrally formed with the base body 11 for fixing and installing the guide rail 3, a centering groove 13 provided in the center above the extension support arm 12 for positioning and placing the guide rail 3, and limit bars 14 integrally formed on both sides above the base body 11 for limiting the left and right swinging of the first sliding seat 4.

[0024] The cylinder drive group 2 includes a first drive cylinder 21 fixed on the base 1 for driving the second sliding seat 8 to slide and adjust, a second drive cylinder 22 stacked above the first drive cylinder 21, the output end of which is connected to the first sliding seat 4, a cylinder mounting plate 23 fixed vertically on the mounting base 1 by bolts and the side surfaces of which are fixed with bolts to the first drive cylinder 21 and the second drive cylinder 22, and a connecting shaft 24 with one end connected to the output end of the first drive cylinder 21 and the other end assembled with the second sliding seat 8. The connecting shaft 24 passes through the cylinder mounting plate 23, the first sliding seat 4 and the limit block 6 in sequence, and does not contact the cylinder mounting plate 23, the first sliding seat 4 and the limit block 6. Specifically, the first drive cylinder 21 can drive the second sliding seat 8 to slide and adjust through the connecting shaft 24.

[0025] The lower end of the first sliding seat 4 is fixed with a first sliding seat assembly block 41 by bolts. Specifically, the first sliding seat assembly block 41 is assembled on the guide rail 3, and the two sides of the lower end of the first sliding seat 4 are gap-matched with the limit bars 14 on both sides above the base body 11, which can prevent the first sliding seat 4 from swinging left and right during the sliding process on the guide rail 3, and can improve the stability of the sliding adjustment of the first sliding seat 4.

[0026] The bottle body rotation assembly 5 includes a rotating motor 51 fixedly installed on one side above the first sliding seat 4 by bolts, and a bottle bottom holder 52 located on the other side above the first sliding seat 4 and fixedly installed with the output end of the rotating motor 51. Specifically, the output end of the rotating motor 51 passes through the first sliding seat 4 and is fixedly installed with the bottle bottom holder 52. The bottle bottom holder 52 is detachable and can be replaced according to bottles 9 of different sizes.

[0027] The limit stop 6 is arched, and the lower end is clamped with the guide rail 3. The upper end of the limit stop 6 is also provided with a limit screw 61 for controlling the sliding stroke of the first sliding seat 4. Specifically, the limit screw 61 is assembled on the limit stop 6, and the end passes through the limit stop 6 and extends to the contact surface between the limit stop 6 and the first sliding seat 4. The screw-out length of the limit screw 61 can be adjusted according to the size of the bottle body 9, replacing the limit stop 6 to limit the first sliding seat 4.

[0028] A sheet metal part 71 is provided at one end of the dust cover 7 close to the second sliding seat 8. Specifically, the sheet metal part 71 is fixed to the extension arm 12 and the dust cover 7 by screws, thereby fixing and rotating the dust cover 7.

[0029] The second sliding seat 8 includes a second sliding seat body 81, a second sliding seat assembly block 82 fixed to the lower end of the second sliding seat body 81 by bolts and assembled with the guide rail 3, a conical head 83 with a built-in bearing assembled on one side of the upper end of the second sliding seat body 81, a connecting shaft assembly hole 84 provided at the lower end of the second sliding seat body 81, a first clamping bolt 85 assembled on the side of the lower end of the second sliding seat body 81 and extending to the connecting shaft assembly hole 84, and a connecting shaft tightening auxiliary frame 86 provided at the lower end of the second sliding seat body 81. Specifically, after the connecting shaft 24 passes through the connecting shaft assembly hole 84, the first clamping bolt 85 is rotated to tighten the connecting shaft 24. At this time, the first driving cylinder 21 can drive the second sliding seat 8 to slide and adjust through the connecting shaft 24. In addition, the conical head 83 can cooperate with the bottle bottom holder 52 to fix the bottle body 9 and is driven to rotate by the rotary motor 51, providing a guarantee for the subsequent silk screen processing of the bottle body 9.

[0030] The connecting shaft fastening auxiliary frame 86 includes an auxiliary screw 861 with a rotating wheel mounted on one end and the other end extending through the second sliding seat body 81, an assembly plate 862 whose upper end is sleeved on the auxiliary screw 861 and fixed by a nut, an assembly plate through-hole 863 provided on the assembly plate 862 and corresponding in position to the connecting shaft assembly hole 84, and a second clamping bolt 864 extending from the side of the assembly plate 862 to the connecting shaft assembly hole 84. Specifically, when the second sliding seat body 81 cannot be fixedly mounted with the connecting shaft 24 after sliding adjustment, the auxiliary screw 861 can be adjusted to move the assembly plate 862 toward the connecting shaft 24. The connecting shaft 24 can then pass through the assembly plate through-hole 863 and be squeezed and fixed by the second clamping bolt 864. At this time, the first driving cylinder 21 can still drive the second sliding seat 8 to slide and adjust via the connecting shaft 24.

[0031] It should be further explained that, under normal circumstances, after the connecting shaft 24 passes through the connecting shaft assembly hole 84, the connecting shaft 24 is tightened by rotating the first tightening bolt 85, and the connecting shaft tightening auxiliary frame 86 does not need to adjust the auxiliary adjustment screw 861, and the second tightening bolt 864 can be directly tightened to squeeze and fix the connecting shaft 24. At this time, the function of the connecting shaft tightening auxiliary frame 86 is to further tighten the connecting shaft 24.

[0032] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto.
