Description

Technical Field

[0001] The utility model relates to the field of container manufacturing, in particular to a container top plate spray gun frame lifting device. Background Art

[0002] Currently, the distance between the spray gun and the top of the container for automatic spraying of the container roof is fixed, and the spray gun rack has only two fixed positions for adjustment, corresponding to the two types of boxes: high box and flat box. The extension and contraction of the cylinder corresponds to the two positions of the spray gun rack, thereby realizing the spraying of both high box and flat box. This mechanism cannot make real-time fine adjustments to the distance from the spray gun to the container roof as the gun nozzle wears and the paint is replaced during the production process, thereby ensuring the quality of the paint film thickness of the spraying. If the distance from the spray gun to the top plate needs to be adjusted, it can only be operated at the end of production, and each gun needs to be re-fixed, which is inefficient.

[0014] See also Figure 1-3 The utility model discloses a container roof spray gun frame lifting device in an embodiment. A mounting frame 1 is arranged outside the container 2. The mounting frame 1 includes a plurality of columns 11 arranged on both sides of the container 2 and a crossbeam 12 supported by the columns 11. The crossbeam 12 is located above the top plate of the container 2. The lifting device is arranged on the upper side of the container 2 and on the crossbeam 12.

[0015] The lifting device includes a power component 4 and a transmission component 5. The power component 4 is correspondingly connected to two transmission components 5, and the two transmission components 5 are respectively connected to the two ends of a spray gun rack 6 with a certain length. A plurality of spray guns 7 are evenly arranged on the spray gun rack 6. The power component 4 can adjust the horizontal height of the spray gun rack 6 and the spray gun 7 in real time.

[0016] Specifically, the power assembly 4 includes a motor 41 and a reducer 42 connected in sequence, and the transmission assembly 5 includes a steering gear 52. The power assembly 4 not only uses the steering mechanism of the steering gear 52, but also combines the reduction mechanism of the steering gear 52. On the basis of the reducer 42, the speed of the motor 41 is further reduced, thereby providing a basis for real-time micro-control of the spray gun frame 6. The power assembly 4 and the steering gear 52 are both arranged on a fixed frame 3, and the fixed frame 3 is arranged on the crossbeam 12 of the mounting frame 1. The motor 41 is fixed to the upper side of the reducer 42, and the output end of the motor 41 is directly connected to the input end of the reducer 42. The reducer 42 is fixed to the middle of the fixed frame 3, and the reducer 42 has two symmetrical output ends, each of which is respectively connected to the input ends of the two steering gears 52, and the output ends of the two steering gears 52 are respectively connected to the two ends of the spray gun frame 6. The entire lifting device is a symmetrical structure, which is more stable. At the same time, the two ends of the spray gun frame 6 can be synchronously controlled to ensure that the entire spray gun frame 6 can be stably lifted and lowered.

[0017] The transmission assembly 5 also includes a first transmission shaft 51 and a second transmission shaft 53, and the two ends of the first transmission shaft 51 are respectively connected to the output end of the power assembly 4 and the input end of the diverter 52; the output end of the diverter 52 is fixed with a second transmission shaft 53, and the second transmission shaft 53 is connected to the fixed frame 3 with a bearing. Two sprockets 54 are fixed on the second transmission shaft 53, and each sprocket 54 is correspondingly provided with a chain 55, and each group of corresponding chains 55 cooperates with the sprocket 54. One end of the chain 55 is fixedly connected to the spray gun frame 6. Thus, each end of the spray gun frame 6 can be lifted and lowered using two parallel chains 55, and the lifting process can be more stable. By driving the lifting mechanism of the sprocket 54 and even the chain 55 through the power assembly 4, accurate, continuous and dynamic adjustment can be achieved to meet the requirements of containers 2 of various heights and different spraying requirements.

[0018] Under the action of external force, the fixing frame 3 can move horizontally along the crossbeam 12 relative to the mounting frame 1, and can adjust the horizontal position of the spray gun frame 6 relative to the top plate of the container 2, thereby realizing real-time fine adjustment of the spray gun 7 at various horizontal positions of the top plate.

[0019] In the traditional system, if the distance between the spray gun 7 and the top plate needs to be changed, it may be necessary to re-fix it after the production is completed, which is time-consuming and inaccurate. However, the utility model can make fine adjustments according to the type of paint and the wear of the gun nozzle during the spraying process without interrupting production, thereby ensuring the spraying quality and film thickness, and greatly improving efficiency. In addition, the utility model can achieve continuous and dynamic adjustment through the lifting mechanism of the motor 41, the reducer 42 and the chain 55 to meet the requirements of containers 2 of various heights and different spraying requirements. There is no need to modify the spray gun holder 6 on the upper side of the top plate when spraying containers 2 of different heights, thereby improving the versatility and adaptability of the equipment.

[0020] The utility model can be further integrated with automatic spraying equipment, using sensors and control algorithms: a sensor can be set on the spray gun 7 to feedback the pressure and flow at the nozzle, and the appropriate distance can be calculated through the control algorithm to automatically control the motor 41 for real-time adjustment; or a new power mechanism can be set on the spray gun frame 6 to adjust the rotation angle of the spray gun 7 relative to the spray gun frame 6, expand the range that the spray gun 7 can cover, and realize a more automated and intelligent spraying operation. In this way, a more accurate and efficient spraying process can be achieved.

[0021] In summary, the utility model sets a power component 4 and a transmission component 5 above the container 2, and uses a chain 55 lifting mechanism driven by a motor 41 and a reducer 42, which has high flexibility and can perform real-time micro-control on the lifting of the spray gun holder 6; it can not only realize real-time micro-adjustment of the distance between the spray gun 7 and the top plate of the container 2 during the production process, but also more accurately control the spraying quality and film thickness, thereby improving the spraying quality and efficiency; it can also meet the needs of containers 2 of various heights and different spraying requirements, and has strong adaptability.
