Description

Technical Field

[0001] The utility model relates to the technical field of plastic product spraying, and more particularly to a plastic product spraying machine. Background Art

[0002] In the current plastic product production process, the sprayer is a key equipment that directly affects the appearance quality of the product and the uniformity of the coating. However, the existing sprayer technology has some problems in structure and operation, which limit the flexibility and efficiency of the equipment.

[0003] First, many existing spray machines have relatively simple structures and lack the necessary complexity and flexibility. The nozzle angles of these devices are often fixed and cannot be adjusted according to different spraying requirements. This limitation makes the equipment unable to handle plastic products with complex shapes or different sizes, and it is impossible to achieve the ideal spraying effect, thus affecting the overall quality of the product.

[0004] Secondly, most existing sprayer nozzles adopt a fixed structure, which means that once the nozzle is worn or needs to be replaced, the entire equipment may need to be shut down for maintenance, which not only prolongs the maintenance time, but also increases the downtime of the equipment, affecting the continuity of production. Although some sprayers adopt a detachable nozzle structure, the installation and disassembly process is usually cumbersome and requires professional operation, which undoubtedly increases the complexity of the operation and the potential error rate.

[0005] In addition, although structures that can achieve rapid replacement of nozzles have appeared in the prior art, these designs often have defects in the sealing of the joints. If the connection between the nozzle and the sprayer is not tightly sealed, paint leakage may occur, which not only wastes precious paint resources, but may also cause environmental pollution and affect the quality and uniformity of the spraying.

The driving assembly 22 drives the chain 3 to run through the gear 21 connected to the output end, and then the connecting sleeve drives the connecting seat 8 and the hard tube 4 and the nozzle 20 to move, thereby realizing automated spraying processing. When the angle of the nozzle 20 needs to be adjusted, the hydraulic cylinder 5 is turned on, and the hydraulic cylinder 5 pushes the connecting frame 7 to move through the hydraulic rod 6 connected to the output end, and then The connecting frame 7 will drive the hard pipe 4 to move, and then the hydraulic cylinder 5 will rotate on the corresponding connecting seat 8, and the connecting block 9 will rotate with the hard pipe 4 around the other connecting seat 8, so as to achieve the purpose of adjusting the angle of the nozzle 20. After the adjustment is completed, the hydraulic cylinder 5 can be closed.

[0040] More specifically, since an inclined slope 31 is provided in the quick-change groove 24, when one end of the quick-change frame 23 is fully inserted into the quick-change groove 24, the slope 31 will drive the quick-change tube 18 to press the sealing ring 30, thereby improving the sealing of the connection. At the same time, the multiple sealing plates 28 provided at one end of the quick-change tube 18 will be fully engaged with the sealing groove 29 opened on the inner side of the connecting tube 10, thereby further enhancing the sealing performance of the pipeline connection.

[0041] In summary, when the overall equipment is in use or running: when the equipment needs to be used to spray plastic products, one end of the hard pipe 4 is passed through the connecting block 9 and connected to the external conveying equipment, and then the paint is conveyed to the hard pipe 4 through the external conveying equipment, and then sprayed to the plastic product through the nozzle 20, and then the driving assembly 22 is turned on, and the driving assembly 22 drives the chain 3 to run through the gear 21 connected to the output end, and then the connecting sleeve drives the connecting seat 8 and the hard pipe 4 and the nozzle 20 to move, thereby realizing automated spraying processing. When the angle of the nozzle 20 needs to be adjusted, the hydraulic cylinder 5 is turned on, and the hydraulic cylinder 5 pushes the connecting frame 7 into The connecting frame 7 will move, and then the hard pipe 4 will move, and then the hydraulic cylinder 5 will rotate on the corresponding connecting seat 8, and the connecting block 9 will rotate with the hard pipe 4 around the other connecting seat 8, so as to achieve the purpose of adjusting the angle of the nozzle 20. After the adjustment is completed, the hydraulic cylinder 5 can be closed. When the nozzle 20 needs to be replaced, the limiting sleeve 12 is first rotated in the corresponding direction so that the limiting sleeve 12 slides along the fixed plate 19, and then the limiting sleeve 12 will drive the limiting groove 13 and the giving groove 14 to move. When the position of the giving groove 14 corresponds to the position of the quick-changing frame 23, the limiting sleeve 12 is stopped, and then the drawstrings 26 set on both sides are pulled outward at the same time. The drawstrings 26 are pulled outward at the same time. 6 will drive the quick-change sleeves 15 set on both sides to move relatively toward the middle, and then the quick-change sleeve 15 will drive the slider 16 to slide along the slide groove 17, and at the same time the slider 16 will compress the spring 27 set in the slide groove 17. Due to the chamfered structure design on one side of the quick-change sleeve 15, the quick-change sleeve 15 will gradually push the quick-change rod 11 open, and then the quick-change rod 11 will drive the quick-change frame 23 to move outward, and at the same time the quick-change frame 23 will drive the tension spring 25 set inside to stretch. When the pull belt 26 can no longer be pulled, one end of the quick-change frame 23 is flush with the inner wall of the connecting pipe 10, and then the nozzle 20 is pulled out, so that the quick-change tube 18 is removed from the connecting pipe 10, and then a new one is taken out. The nozzle 20 of the new nozzle 20 is inserted into the quick-change tube 18 provided at one end of the new nozzle 20 into the connecting tube 10, and then the drawstring 26 is loosened, and the spring 27 drives the slider 16 and the quick-change sleeve 15 to reset, and then the quick-change rod 11 will lose the limit of the quick-change sleeve 15, and then the tension spring 25 will drive the quick-change rod 11 and the quick-change frame 23 to reset, so that one end of the quick-change frame 23 is completely inserted into the quick-change groove 24, and the quick-change rod 11 is engaged, and then the limiting sleeve 12 is rotated in the opposite direction so that the position of the giving groove 14 no longer corresponds to the position of the quick-change frame 23, and then the limiting groove 13 will limit the quick-change frame 23 to prevent it from moving, thereby ensuring the stable connection of the quick-change tube 18.

[0042] Since the quick-change groove 24 is provided with an inclined slope 31, when one end of the quick-change frame 23 is fully inserted into the quick-change groove 24, the slope 31 will drive the quick-change tube 18 to press the sealing ring 30, thereby improving the sealing performance of the connection. At the same time, the multiple sealing plates 28 provided at one end of the quick-change tube 18 will be fully engaged with the sealing groove 29 opened on the inner side of the connecting tube 10, thereby further strengthening the sealing performance of the pipeline connection.
