[0001] The invention relates to the technical field of bottle cap spraying, and in particular to a bottle cap fixing fixture and a spraying conveying device. Background Art

[0002] The surface of the bottle cap of the wine bottle needs to be sprayed with metallic paint. During the spraying process, automatic spraying equipment is required. The bottle cap needs to be installed on a fixture and then sprayed with the automatic spraying equipment.

[0003] For the bottle caps of some wine bottles, it is necessary to spray one color of metallic paint on the side of the bottle cap and another color of metallic paint on the top of the bottle cap. Conventional clamps only have the function of clamping and fixing. Before spraying the top of the bottle cap, it is necessary to cover the bottle cap with a collar to cover the outer side of the bottle cap, while the upper end of the bottle cap is exposed. The exposed upper end of the bottle cap is sprayed with an automatic spraying device. This method has low production efficiency, and there is a gap between the collar and the bottle cap, and the metallic paint easily enters through the gap, causing the metallic paint to contaminate the paint layer on the outer side of the bottle cap.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0040] like Figures 1 to 6 The present embodiment discloses a spray conveying device, including a bottle cap fixing fixture having a support rod 10, a slider 71 connected to the lower end of the support rod 10, a guide rail 72 having a groove 21 and a driving device 73 for driving the slider 71 to slide along the slide groove 721, and the guide rail 72 is provided with a slide groove 721 for the slider 71 to slide.

[0041] The spraying and conveying device of this embodiment uses a bottle cap fixing clamp to fix the bottle cap 80, and the lower end of the support rod 10 is connected to the slider 71. The slider 71 is driven by the driving device 73 to slide along the slide groove 721 of the guide rail 72, thereby realizing automatic conveying. After conveying to the spraying position, the upper end surface of the bottle cap 80 is sprayed by a spray gun or other spraying tools, and the spraying efficiency is high and the degree of automation is high.

[0042] Furthermore, the bottle cap fixing fixture of the present embodiment includes a support rod 10, a lower shell body 20 detachably fixed to the support rod 10, an upper cover 30 which is openably and closably arranged on the upper end of the lower shell body 20, and a retaining ring 40 detachably fixed to the upper cover 30; the upper end of the groove 21 is open; the retaining ring 40 is formed with a through hole 41 which penetrates the groove 21, and the shape of the through hole 41 is adapted to the outer shape of the edge of the upper end face of the bottle cap 80.

[0043] The bottle cap fixing fixture of the present embodiment is provided with an openable and closable upper cover 30. Before installing the bottle cap 80, the upper cover 30 is first opened, and then the bottle cap 80 is installed in the groove 21, and then the upper cover 30 is closed. The retaining ring 40 on the inner side of the upper cover 30 is used to block the upper edge of the bottle cap 80, so as to prevent the paint from flowing downward from the upper edge of the bottle cap 80, causing the paint to contaminate the side paint film of the bottle cap 80. The structure is ingenious.

[0044] In addition, in this embodiment, the upper cover 30 and the retaining ring 40 are designed to be detachable, and different upper covers 30 can be replaced according to the shape of the upper end edge of the bottle cap 80, so that the shape of the through hole 41 of the upper cover 30 is compatible with the shape of the upper end edge of the bottle cap 80 to meet different spraying requirements.

[0045] For further information, please refer to Figure 4 and Figure 6The bottle cap fixing fixture of this embodiment further includes a clamping mechanism 50, and the groove 21 is a circular structure; the clamping mechanism 50 includes a plurality of push plates 51 distributed along the circumference inside the groove 21, and a first spring 52 disposed in the groove 21 and pushing the push plates 51 toward the center of the groove 21; the plurality of push plates 51 surround to form a clamping area 22 with a variable inner diameter. With such a design, when bottle caps 80 with different outer diameters are loaded into the clamping area 22, the clamping area 22 can be clamped under the elastic action of the first spring 52. The size is adjusted according to the diameter of the bottle cap 80, so that the bottle cap 80 in the clamping area 22 is always in a clamped state to avoid loosening, and the push plate 51 is distributed along the circumference. For the clamping of the circular bottle cap 80, the axis of the bottle cap 80 can be collinear with the axis of the circular clamping area 22, so that when the upper cover 30 is closed, the axis of the through hole 41 of the retaining ring 40 can also be collinear with the axis of the bottle cap 80, so that the through hole 41 of the upper cover 30 and the upper end surface edge of the bottle cap 80 are more adapted, thereby improving the accuracy of the spraying area.

[0046] Please refer to Figure 6 A guide column 53 extending radially along the groove 21 is provided at the bottom of the groove 21, and the first spring 52 is sleeved on the guide column 53. By providing the guide column 53, the first spring 52 can be prevented from being offset, thereby ensuring that the push plate 51 can move smoothly along the radial direction of the groove 21.

[0047] For further information, please refer to Figure 4 In this embodiment, the push plate 51 is provided with an inclined guide surface 511 at the upper end facing the clamping area 22. By providing the inclined guide surface 511, when the bottle cap 80 is loaded, the bottom of the bottle cap 80 can be quickly guided to be loaded into the clamping area 22.

[0048] Please refer to Figure 6 The bottle cap fixing fixture also includes a pushing mechanism 60; the pushing mechanism 60 includes a push pin 61 that can be vertically telescopically moved in the clamping area 22, a second spring 62 connected to the lower end of the push pin 61, and an inner hole 23 for the second spring 62 to be vertically telescopically moved is provided at the bottom of the groove 21; after the upper cover 30 is closed, under the elastic action of the second spring 62, the push pin 61 pushes up the bottle cap 80 in the clamping area 22, so that the upper end surface edge of the bottle cap 80 is against the retaining ring 40, so that the upper end surface edge of the bottle cap 80 is closely fitted with the bottom surface of the retaining ring 40, thereby preventing paint from entering the groove 21 and causing the paint layer on the outer side of the bottle cap 80 to be contaminated; after the upper cover 30 is opened, under the elastic action of the second spring 62, the push pin 61 can move upward in the vertical direction to push the bottle cap 80 out of the clamping area 22, so that the staff can take out the bottle cap 80.

[0049] Furthermore, one end of the upper cover 30 is hinged to the lower shell 20 through a hinge, and the other end is snap-fitted to the lower shell 20. The opening and closing structure of the upper cover 30 is simple, and the opening and closing operation is easy.

[0050] Furthermore, the upper cover 30 is threadedly connected to the retaining ring 40, which is convenient for disassembly and assembly. The height of the retaining ring 40 can be fine-tuned by rotating the retaining ring 40 to adapt to bottle caps 80 of different heights. In addition, by fine-tuning the height of the retaining ring 40, it is also possible to avoid scratching the edge of the upper end surface of the bottle cap 80 due to excessive thrust of the second spring 62.

[0051] For further information, please refer to Figures 1 to 3 The lower end of the support rod 10 is rotatably connected to the slider 71, and a rack 74 is fixed in the slide groove 721. The support rod 10 is provided with a gear 75 meshing with the rack 74. When the driving device 73 drives the slider 71 to slide along the slide groove 721 of the guide rail 72, the gear 75 and the rack 74 mesh together, which can drive the support rod 10 to rotate, thereby achieving a rotary spraying effect of the bottle cap 80.

[0052] In order to improve the stability of the support rod 10 while moving and rotating, the support rod 10 is further sleeved with a bearing 76 , and the bearing 76 is located at the top inner side of the sliding groove 721 .

[0053] Furthermore, the driving device 73 is a belt conveying device, which includes an annular belt and a motor gear set for driving the belt to circulate, and the slider 71 is fixed to the belt of the belt conveying device.
