[0033] S4, tear off the excess film on the periphery of the covering film to expose the complete second coloring area;

[0034] S5, spraying a second glaze color, such as gold, on the outer surface of the bottle body using a spraying device, and the second glaze color will be sprayed on the covering film to prevent the second glaze color from being sprayed on the first coloring area under the covering film, so that the first coloring area retains the first glaze color;

[0035] S6, tearing off the covering film to obtain a finished bottle body, wherein the first coloring area of ​​the finished bottle body is the first glaze color, and the second coloring area is the second glaze color.

[0036] This embodiment can accurately spray two different glaze colors on the surface of the bottle body, the junction of the two glaze colors is more regular, and the color separation spraying quality is high. After the bottle body is sprayed with the first glaze color, the slitting machine accurately cuts the heat shrinkable tearable film attached to the bottle body into two parts, and the covering film accurately covers the first coloring area. When the excess film is torn off and the second glaze color is sprayed, the second glaze color is accurately sprayed on the second coloring area, thereby realizing the partitioning coloring of the first coloring area and the second coloring area of ​​the bottle body, spraying the first glaze color and the second glaze color respectively, and the edges of the junction of the two glaze colors are regular, and the color separation spraying quality is high and the efficiency is high.

[0037] Embodiment 2

[0038] like Figure 1-Figure 5 As shown, this embodiment proposes a method for efficiently spraying a bottle body based on a slitting machine. Compared with the first embodiment, in this embodiment, the slitting machine includes a machine base 1, a machine cover 2 provided on the machine base 1 and having an inlet and outlet, a control box 3 provided on the machine cover 2, a laser slitting mechanism provided on the machine base 1 and located inside the machine cover 2, a clamping mechanism for clamping the bottle body, and a second servo module 10 provided on the machine base 1 and driving the clamping mechanism to reciprocate to the bottle body clamping station and the film slitting station. The bottle body clamping station is located outside the inlet and outlet of the machine cover 2, and the film slitting station is located below the laser slitting mechanism. The bottle body is accurately clamped to the clamping mechanism at the bottle body clamping station, and then the clamping mechanism is moved to the film slitting station by the second servo module 10, and the heat shrinkable tearable film attached to the lower bottle body is laser cut by the laser slitting mechanism.

[0039] like Figure 4As shown, the laser cutting mechanism includes a laser 5, a support 4 arranged on a machine base 1, and a first servo module 6 arranged on the support 4 and used to adjust the lateral position and height of the laser 5. The position and height of the laser 5 are adjusted by the first servo module 6 to ensure that the laser 5 can effectively cut the heat shrinkable tearable film below without damaging the bottle body.

[0040] like Figure 3 and Figure 4 As shown, a fan 7 is provided in the hood 2, an air outlet 9 is provided at the top of the hood 2, and an air duct 8 is connected between the fan 7 and the air outlet 9. The smoke generated during laser cutting is sucked in by the fan 7, transported through the air duct 8, and discharged from the air outlet 9.

[0041] like Figure 3-Figure 5 As shown, the clamping mechanism includes a moving platform 11 arranged at the moving end of the second servo module 10, a supporting assembly arranged on the moving platform 11, a profile rail 12 arranged on the supporting assembly, a mounting frame 15 and a mounting platform 23 arranged on the profile rail 12, a rotating shaft rotatably arranged on the mounting frame 15, a driving assembly arranged on the mounting frame 15 and driving the rotating shaft to rotate, an abutting platform 22 arranged at the head of the rotating shaft, a cylinder 24 arranged on the mounting platform 23, and a pressing platform 25 rotatably arranged at the moving end of the cylinder 24 and facing the abutting platform 22. The bottle body is placed flat, the bottle bottom is pressed against the abutting platform 22, the bottle mouth is facing the pressing platform 25, and the pressing platform 25 is driven by the cylinder 24 to move so that the bottle body is clamped between the abutting platform 22 and the pressing platform 25. The driving assembly drives the rotating shaft to rotate, the rotating shaft drives the abutting platform 22 to rotate, and the abutting platform 22 drives the bottle body and the pressing platform 25 to rotate, so as to adjust the orientation of the bottle body. A device capable of detecting the inclination angle of a workpiece may be arranged on the machine base 1 at one side of the bottle body clamping station to detect whether the bottle body is adjusted to a horizontal state.

[0042] like Figure 5 As shown, the support assembly includes a first bracket 13 and a second bracket 14 arranged side by side on the moving platform 11, the profile rail 12 is rotatably mounted on the first bracket 13, and the second bracket 14 has arc holes distributed around the central axis of rotation of the profile rail 12. The profile rail 12 has a threaded hole corresponding to the arc hole, and the threaded hole of the profile rail 12 is threadedly connected with a first bolt or a first threaded knob that passes through the arc hole and is tightened on the second bracket 14. By loosening the first bolt or the first threaded knob, the profile rail 12 can be rotated around the first bracket 13 to adjust the inclination angle of the profile rail 12, thereby adjusting the inclination angle of the clamped bottle body, and then tightening the first bolt or the first threaded knob to achieve angle adjustment. For the bottle body in this embodiment, the profile rail 12 needs to be adjusted to a horizontal state, so that the bottle body can be finally clamped in a horizontal state through the clamping mechanism.

[0043] like Figure 5As shown, multiple groups of supporting components are arranged on the profile rail 12, and the supporting components include a slide 26 horizontally slidingly arranged on the profile rail 12, two support frames 27 symmetrically arranged on both sides of the slide 26, and a support ring 28 rotatably arranged at the top of the support frame 27, and the support frame 27 has a strip hole. A second bolt or a second threaded knob threadedly connected to the slide 26 and pressed against the support frame 27 is passed through the strip hole. The height and tilt angle of the support frame 27 can be adjusted by loosening the second bolt or the second threaded knob, thereby adjusting the height and orientation of the top support ring 28. After tightening the second bolt or the second threaded knob, the support ring 28 can support the bottle body under the bottle body, that is, auxiliary support the bottle body, so that the bottle body can maintain stability and the heat shrinkable tearable film on the bottle body can be accurately cut by the laser 5.

[0044] like Figure 5 As shown, the driving assembly includes a reducer 17 arranged on the mounting frame 15, a motor 16 arranged on the reducer 17 and connected to the input end of the reducer 17, a first pulley 18 connected to the output end of the reducer 17, a second pulley 19 arranged on the rotating shaft, a tensioning wheel 20 rotatably arranged on the mounting frame 15, and a belt 21 sleeved on the first pulley 18 and the second pulley 19 and the outer peripheral surface of which is pressed by the tensioning wheel 20. The motor 16 can drive the first pulley 18 to rotate through the reducer 17, the first pulley 18 drives the second pulley 19 to rotate through the belt 21, and the second pulley 19 drives the abutment platform 22 to rotate through the rotating shaft, and the entire power transmission process is stable. After the belt 21 is tensioned inwardly, the wrap angle between the belt 21 and the first pulley 18 and the second pulley 19 can be increased, which is convenient for transmission. The motor 16 adopts a servo motor. In order to improve the accuracy of transmission, the first pulley 18 and the second pulley 19 adopt synchronous pulleys, and the belt 21 adopts a synchronous belt.

[0045] This embodiment can cut the heat-shrinkable tear film attached to the bottle body into a covering film and a redundant film by laser cutting. The cutting is precise and the edge of the covering film is regular. After the second glaze color is sprayed on and the covering film is torn off, the edge of the junction of the first glaze color and the second glaze color is regular, and the color separation spraying quality of the entire bottle body is high. The slitting machine laser cutting method is more efficient than the manual sticker shielding method and can meet the production requirements. If the bottle body surface has a curvature and the sticker does not have good ductility, wrinkles are likely to occur, and the effect is not as good as the heat-shrinkable tear film used in this embodiment. In addition, the manual sticker shielding method is not accurate and costly, not as accurate and costly as the slitting machine laser cutting method.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
