[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The utility model provides a technical solution for a raw material spraying device for producing safety helmets: it includes a rotatable rotating frame 1, the rotating frame 1 is arranged in a fuselage 10, and vacuum suction cup fixing parts 2 are movably and symmetrically provided on the rotating frame 1 for fixing the safety helmets to be sprayed, and the spraying is achieved by moving the spraying arm up and down and left and right to spray, so as to achieve the purpose of spraying raw materials on the safety helmets to be sprayed. The symmetrically arranged vacuum suction cup fixing parts 2 can make the safety helmets to be sprayed on one row of vacuum suction cup fixing parts 2 be sprayed on the inner side of the fuselage 10, while the safety helmets to be sprayed on the row of vacuum suction cup fixing parts 2 near the door side of the fuselage 10 can enable workers to perform the next sequence operation at the same time.

[0026] The vacuum suction cup fixture 2 is connected to an external air source, and the external air source can provide negative pressure to the vacuum suction cup fixture 2, so that the safety helmet to be sprayed can be firmly sucked onto the vacuum suction cup fixture 2.

[0027] The rotating frame 1 is also provided with a positioning member 4 arranged around the vacuum suction cup fixing member 2, which is used to pre-position the safety helmet to be sprayed to prevent it from tilting when being placed in the device, thereby affecting the spraying effect of the safety helmet.

[0028] A lifting plate 5 is connected to the rotating frame 1, wherein the vacuum suction cup fixing part 2 is connected to the lifting plate 5, and the lifting plate 5 can drive the vacuum suction cup fixing part 2 to rise and fall. Before placing the safety helmet to be sprayed into the device, first ensure that the lifting plate 5 drives the vacuum suction cup fixing part 2 to the lowest point, and then the safety helmet to be sprayed can be placed in the positioning part 4 for preliminary positioning, and then the vacuum suction cup fixing part 2 is driven to rise by the lifting plate 5, so that the top of the vacuum suction cup fixing part 2 contacts and attracts the safety helmet to be sprayed, so as to achieve the purpose of placing the safety helmet to be sprayed correctly and achieving uniform spraying, thereby improving the spraying effect of the device.

[0029] Specifically, the vacuum suction cup fixing part 2 includes a fixed suction cup 21, which is a vacuum suction cup. The negative pressure is increased by an external air source to attract and fix the inner wall of the safety helmet to be sprayed. The vacuum suction cup has strong adaptability and can be adjusted according to the shape and material of the object to be adsorbed.

[0030] The bottom of the fixed suction cup 21 is fixedly connected to a connecting pipe 22 that is rotatably connected to the rotating frame 1. By rotating the connecting pipe 22, the fixed suction cup 21 can be driven to rotate, and then the safety helmet to be sprayed can be driven to rotate, so that the spray arm can spray the safety helmet to be sprayed evenly in the circumference. The outer wall of the connecting pipe 22 is connected to a first rotating joint 23 connected to the lifting plate 5, and negative pressure suction can be provided to the connecting pipe 22 and the fixed suction cup 21 through the first rotating joint 23 without affecting the rotation of the connecting pipe 22.

[0031] Specifically, the bottom of the lifting plate 5 is provided with a driving gear 6 and a driven gear 7, which are engaged with the driven gear 7. The bottom of the lifting plate 5 is also fixed with a driving member 14 through a mounting frame 13. The driving member 14 can be a motor. The driving member 14 can drive the driving gear 6 to rotate, thereby rotating the driven gear 7. The center of the driven gear 7 is fixed with a rotating shaft, and the bottom of the connecting pipe 22 is fixedly connected to the rotating shaft of the driven gear 7. As the driven gear 7 rotates, the connecting pipe 22 can be driven to rotate, thereby causing the fixed suction cup 21 to drive the safety helmet to be sprayed to rotate, so that the spray arm can spray the circumference of the safety helmet to be sprayed evenly.

[0032] Specifically, the positioning member 4 includes symmetrically arranged limit plates 41, which are arranged in an arc shape. A placement groove (similar to the shape of the circumferential side edge of the safety helmet) is formed between the two limit plates 41. When the safety helmet to be sprayed is placed into the device, the safety helmet to be sprayed needs to be placed in the placement groove to position the safety helmet to be sprayed in advance.

[0033] The table top of the rotating frame 1 is provided with a mounting groove, the inner wall of the mounting groove is fixedly connected with a slide 42, and the inner wall of the slide 42 is slidably provided with a slide rail 43, wherein the bottom of the limiting plate 41 is integrally formed with a connecting column, the connecting column extends into the mounting groove and is fixedly connected to the slide rail 43. When the limiting plate 41 is moved, the slide rail 43 can slide in the slide 42 to play a limiting and guiding role. By moving the limiting plate 41, the size of the fixed placement groove can be adjusted to accommodate and position safety helmets of different sizes. The table top of the rotating frame 1 (i.e., the top of the mounting groove) is provided with a strip through hole for the movement of the connecting column.

[0034] A locking bolt is also screwed onto the slide rail 43 , and the end of the locking bolt passes through the strip-shaped through hole and extends to the outside of the mounting groove. A backing plate is movably sleeved on the outer wall of the locking bolt.

[0035] Specifically, an auxiliary fixing part 8 is provided on the rotating frame 1 for sliding through. The auxiliary fixing part 8 can assist in fixing the safety helmet to be sprayed, further improving the stability of the safety helmet to be sprayed. The auxiliary fixing part 8 is connected to the lifting plate 5, and the lifting plate 5 can drive the auxiliary fixing part 8 and the vacuum suction cup fixing part 2 to rise and fall synchronously to cooperate with the vacuum suction cup fixing part 2 to fix the safety helmet to be sprayed.

[0036] Specifically, the table top of the rotating frame 1 is penetrated by a guide hole, and the auxiliary fixing part 8 includes a slide bar 81, which passes through the guide hole and is connected to the lifting plate 5. The lifting plate 5 can drive the slide bar 81 to move up and down along the axis of the guide hole. The upper end of the slide bar 81 is hinged with a rotating rod 82, and a first elastic member is provided between the rotating rod 82 and the slide bar 81. The first elastic member is a torsion spring, which can make the rotating rod 82 always have a tendency to rotate in the direction away from the vacuum suction cup fixing part 2. When the lifting plate 5 drives the slide bar 81 to descend, the slide bar 81 can drive the rotating rod 82 to move downward. When the connection between the rotating rod 82 and the slide bar 81 reaches the edge of the guide hole, the rotating rod 82 will enter the guide hole under the guidance of the guide hole. At this time, the rotating rod 82 and the slide bar 81 are in a straight line (that is, both are in a vertical state).

[0037] The end of the rotating rod 82 is connected to an abutment plate 83. When the lifting plate 5 drives the slide bar 81 to rise, the slide bar 81 can drive the rotating rod 82 to move upward. When the connection between the rotating rod 82 and the slide bar 81 reaches the edge of the guide hole and further extends out of the guide hole, the rotating rod 82 is no longer constrained by the guide hole. Under the action of the first elastic force, the rotating rod 82 will rotate in the direction away from the vacuum suction cup fixing part 2 (that is, rotate to both sides), so that the rotating rod 82 drives the abutment plate 83 to abut against the inner walls on both sides of the safety helmet to be sprayed, so as to achieve auxiliary fixation of the safety helmet to be sprayed. A limit piece is provided at the connection between the rotating rod 82 and the slide bar 81 to limit the rotation range of the rotating rod 82.

[0038] Specifically, the end surface of the rotating rod 82 away from the sliding rod 81 passes through and is slidably connected to a support rod 84. A second elastic member 85 is provided between the support rod 84 and the rotating rod 82. The second elastic member 85 is a compression spring. One end of the support rod 84 away from the rotating rod 82 is fixedly connected to the abutment plate 83. The second elastic member 85 can continuously provide an outward thrust to the support rod 84, so that the abutment plate 83 is tightly pressed against the inner wall of the safety helmet to be sprayed, thereby providing stability to the safety helmet to be sprayed.

[0039] Specifically, there are multiple lifting plates 5, and the vacuum suction cup fixing parts 2 are all connected to the lifting plates 5 on the same side, and each row of vacuum suction cup fixing parts 2 corresponds to a lifting plate 5, and multiple lifting plates 5 are provided with lifting parts 9 connected to the rotating frame 1 (the rotating frame 1 includes an upper table and a base frame 11 at the bottom, and the upper table and the base frame 11 are fixedly connected by a connecting shaft 12). The lifting parts 9 are fixed on the base frame 11, and each lifting part 9 also corresponds to a lifting plate 5. The lifting parts 9 can be telescopic cylinders, and each lifting part 9 can drive the corresponding lifting plate 5 to rise and fall separately, thereby making the single row of vacuum suction cup fixing parts 2 rise and fall separately. When the safety helmets to be sprayed on one row of vacuum suction cup fixing parts 2 are being sprayed, the workers can lower the vacuum suction cup fixing parts 2 in the remaining rows, which is convenient for placing new safety helmets to be sprayed while spraying, thereby improving work efficiency.

[0040] Specifically, a second rotary joint 3 is connected to the bottom of the rotating frame 1, and the second rotary joint 3 is connected to the first rotary joint 23. The second rotary joint 3 is simultaneously connected to multiple first rotary joints 23 through an air separator valve to provide negative pressure suction to multiple first rotary joints 23 and the fixed suction cup 21 of the vacuum suction cup fixture 2. The second rotary joint 3 can ensure that the rotating frame 1 can still work normally during rotation.
