Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a conveying line for spraying floor spring components. Background Art

[0002] In order to improve the anti-corrosion and rust resistance, wear resistance and aesthetics of the floor spring parts, the floor spring parts need to be sprayed.

[0003] Existing floor spring spraying equipment generally includes a circulating conveyor line, multiple racks spaced apart on the circulating conveyor line for hanging floor spring components, and a spray assembly for spraying the floor springs. During spraying, the floor spring components are first hung on the racks, which are then driven by the circulating conveyor line to move. Once the floor spring components pass through the spraying range of the spray assembly, the spraying is complete. However, because the floor spring components do not rotate during spraying, the spray assembly sprays the floor spring components from both sides of the conveying direction of the circulating conveyor line. This results in the front and rear sides of the floor spring components not being sprayed, resulting in poor spray quality. Utility Model Content

The mounting bolt passes through the connecting bearing and the sprocket from top to bottom in sequence and is threadedly connected to the mounting nut.

[0008] As an improvement to the above solution, the mounting bolts are placed between two connecting plates.

[0009] As an improvement to the above solution, a hexagonal countersunk hole for accommodating a mounting nut is provided on the lower side of the sprocket.

[0010] As an improvement to the above solution, the conveyor line for spraying floor spring components of the present invention further includes a rubber washer disposed between the connecting bearing and the sprocket and used to abut against the lower side of the inner ring of the connecting bearing and the upper side of the sprocket.

[0028] The following is a further description of the present invention in conjunction with the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical concept claimed in the present invention. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in the present invention are based solely on the drawings and are not intended to limit the present invention.

[0029] like Figures 1 to 6 As shown, a conveyor line for spraying floor spring components according to an embodiment of the present invention includes a frame 100, a conveying mechanism 200, a hanging assembly 300, and a rotating mechanism 400. The conveying mechanism 200 includes an endless conveyor chain 210 mounted on the frame 100 along a conveying path, a plurality of hanging holes 220 spaced apart on the endless conveyor chain 210, and a first speed-regulating drive device 230 mounted on the frame 100 and used to drive the endless conveyor chain 210. In practice, the endless conveyor chain 210 may include a conveyor chain and a plurality of conveyor sprockets that tension the conveyor chain into a desired endless conveying path. In practice, the conveyor chain should pass through the spraying range of the external spraying assembly to enable loading, spraying, and unloading of floor spring components. The first speed-regulating drive device 230 may be connected to the endless conveyor chain 210 via a transmission mechanism to drive a servo motor that operates the endless conveyor chain 210. The first speed-regulating drive device 230 has a speed-regulating function, thereby adjusting the operating speed of the endless conveyor chain 210.

[0030] The hanging assembly 300 includes a connecting base 310 for hanging on the hanging hole plate 220, a movable frame 320 rotatably connected to the connecting base 310 and for hanging the floor spring component, and a sprocket 330 fixed to the movable frame 320. In practice, the movable frame 320 is provided with a hanging structure for hanging the floor spring component, so that the floor spring component can be hung on the movable frame 320. The movable frame 320 can be hung on the hanging hole plate 220, so that the conveying mechanism 200 can drive the floor spring component to move at a preset speed.

[0031] The rotating mechanism 400 includes an endless rotating chain 410 mounted on the frame 100 and disposed on one side of the endless conveyor chain 210 and configured to drive the sprocket 330 to rotate, and a second speed regulating drive device 420 mounted on the frame 100 for driving the endless rotating chain 410. In practice, the endless rotating chain 410 may include a rotating chain and a plurality of rotating sprockets that tension the rotating chain into a desired endless rotating path. Furthermore, the seating range of the endless rotating chain 410 should cover the spraying range of the external spray assembly, allowing the sprocket 330 on the mobile frame 320 to engage with the endless rotating chain 410 within the spraying range of the external spray assembly to drive the floor spring component on the mobile frame 320 to rotate. The second speed regulating drive device 420 may be connected to the endless rotating chain 410 via a transmission mechanism, thereby driving a servo motor that operates the endless rotating chain 410. The second speed regulating drive device 420 has a speed regulating function, thereby adjusting the operating speed of the endless rotating chain 410 and, in conjunction with the sprocket 330, adjusting the rotational speed of the floor spring component hung on the mobile frame 320.

[0032] The specific working principle of the conveyor line for spraying floor spring components of the present invention is as follows: the mobile rack 320 with the floor spring components hung thereon is hung on the hanging hole plate 220 of the circulating conveyor chain 210, and the circulating conveyor chain 210 drives the floor spring components on the mobile rack 320 to move to the spraying area of ​​the external spraying assembly; the circulating rotating chain 410 on the mobile rack 320 engages with the sprocket 330 on the mobile rack 320 so that the mobile rack 320 drives the floor spring components to rotate, so that the floor spring components can be sprayed on all sides by the external spraying assembly, thereby improving the spraying quality; in addition, the conveying speed and rotation speed of the floor spring components can be adjusted according to the spraying needs, thereby further improving the spraying quality of the floor spring components.

[0033] The conveyor line for spraying floor spring components of the present invention cooperates with the frame 100, the conveying mechanism 200, the hanging assembly 300 and the rotating mechanism 400 to rotate the floor spring components during the spraying process. The conveying speed and the rotation speed of the floor spring components can also be adjusted to improve the spraying quality of the floor spring components.

[0034] Specifically, such as Figure 3As shown, the hanging hole plate 220 is preferably provided with a hanging through hole 221 whose axis is perpendicular to the conveying direction of the conveyor chain. The connecting seat 310 includes a seat body 311, a connecting bolt 312, a connecting nut 313 and two connecting plates 314 fixed on the upper side of the seat body 311. A clearance is provided between the two connecting plates 314 for the hanging hole plate 220 to extend into, and both are provided with a mounting through hole 315. The connecting bolt 312 passes through the mounting through hole 315, the hanging through hole 221 and the mounting through hole 315 in sequence and is threadedly connected to the connecting nut 313. Compared with the hanging method of hanging the hook on the hanging hole plate 220, the hanging method of the two spaced connecting plates 314 on the base body 311 and the hanging hole plate 220 being threadedly connected has higher connection strength, and the separation of the connecting base 310 from the hanging hole plate 220 is more difficult, reducing the risk of the connecting base 310 falling from the hanging plate, and can also prevent the connecting base 310 from rotating relative to the hanging hole plate 220, so as to ensure the spraying effect of the floor spring component.

[0035] More specifically, Figure 3 and Figure 4 As shown, the seat body 311 is preferably provided with a receiving through hole 316. The connecting seat 310 further includes a mounting bolt 317, a mounting nut 318, and a connecting bearing 319 mounted in the receiving through hole 316. The mounting bolt 317 passes through the connecting bearing 319 and the sprocket 330 in sequence from top to bottom and is then threadedly connected to the mounting nut 318. In practice, the outer diameter of the head of the mounting bolt 317 is larger than the inner diameter of the connecting bearing 319 and smaller than the outer diameter of the inner ring of the connecting bearing 319, thereby securing the movable frame 320 to the inner ring of the connecting bearing 319. At the same time, the lower portion of the receiving through hole 316 is used to support the stepped surface of the outer ring of the connecting bearing 319, securing the outer ring of the connecting bearing 319 to the seat body 311, thereby achieving a rotational connection between the movable frame 320 and the seat body 311.

[0036] Furthermore, the mounting bolt 317 is preferably placed between the two connecting plates 314, so that the axis of the rotational connection between the movable frame 320 and the base 311 is located between the two connecting plates 314, thereby optimizing the rotational connection structure between the movable frame 320 and the base 311. Furthermore, the underside of the sprocket 330 is preferably provided with a hexagonal countersunk hole 331 for accommodating the mounting nut 318. After the mounting nut 318 is placed in the hexagonal countersunk hole 331, the hexagonal countersunk hole 331 can prevent the mounting nut 318 from rotating. The mounting bolt 317 and the mounting nut 318 can be threadedly connected or released by simply rotating the mounting bolt 317, making assembly and disassembly of the movable frame 320 and the base 311 more convenient.

[0037] It should be noted that the floor spring component spraying conveyor line of the present invention also preferably includes a rubber washer 500 disposed between the connecting bearing 319 and the sprocket 330 and configured to abut against the lower side of the inner ring of the connecting bearing 319 and the upper side of the sprocket 330. The rubber washer 500 prevents the upper side of the sprocket 330 from abutting against the outer ring of the bearing, thereby preventing the upper side of the sprocket 330 from abutting against the outer ring of the bearing, thereby preventing the resistance generated by the abutment between the upper side of the sprocket 330 and the outer ring of the bearing from hindering the rotation of the movable frame 320 relative to the base 311.

[0038] It should be noted that the hanging plate 220 preferably has a plurality of hanging holes 221 spaced vertically apart. In practice, the height adjustment of the circulating chain 410 covers the coverage of the adjusted sprocket 300, ensuring that the sprocket 300 can engage with the circulating chain 410 even after the height adjustment. By changing the hanging holes threaded on the connecting seat 310, the position of the movable frame 320 relative to the hanging plate 220 can be changed, thereby adjusting the vertical position of the movable frame 320 to better match the vertical position of the external spray assembly, ensuring the spraying effect.

[0039] In addition, the floor spring component spraying conveyor line of the present invention preferably further includes a control cabinet 600, to which both the first speed regulating drive device 230 and the second speed regulating drive device 420 are electrically connected. The control cabinet 600 can be positioned within the floor spring component spraying conveyor line for operator control and adjustment, and can be equipped with a PLC and a control panel to centrally control the operating status and speed of the first and second speed regulating drive devices 230, 420, facilitating operator adjustment of the operating status of the floor spring component spraying conveyor line.

[0040] The above are only specific embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
