Description

Technical Field

[0001] This utility model relates to the field of material packaging and transportation technology, and in particular to a flow channel opening and closing conveying device. Background Technology

[0002] In the field of material packaging and transportation technology, conveyor belts, as core equipment for continuously transporting workpieces, are widely used in industrial scenarios such as food processing, electronics manufacturing, and automotive parts assembly. With the increasing automation of production lines and the increasingly dense equipment layout, conveyor belts often need to traverse multiple process areas, creating a "segmented" occupation of operating space. Traditional conveyor devices are mostly fixed installation structures, and their conveying lines divide the equipment area into independent blocks. Workers must travel long distances to cross the conveyor belt to reach the target area, significantly reducing inspection and maintenance efficiency. More importantly, in emergencies such as fires or equipment failures (e.g., downtime due to workpiece jamming), fixed conveyor belts directly block escape routes, preventing workers from evacuating quickly and posing serious safety hazards.

[0003] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

[0023] Please see Figures 1 to 7 A flow channel opening and closing conveying device includes a mounting frame 10, a conveying assembly 20 for conveying workpieces, and a connecting assembly 30 connected to the mounting frame 10 and the conveying assembly 20 so that the end of the conveying assembly 20 is rotatably mounted above the mounting frame 10. Specifically, in this embodiment, by setting the rotating assembly, the conveying assembly 20 has a working state in which it is horizontally set above the mounting frame 10 for docking with an external track to convey workpieces, and a tilted state in which it is flipped upward relative to the mounting frame 10, thereby forming a passageway for workers to pass through.

[0024] The present invention relates to a flow channel opening and closing conveyor device, which, through the setting of mounting frame 10, conveying component 20 and connecting component 30, can form a pedestrian passage that can be passed by people as needed, providing an ideal operator direct passage solution for the conveyor belt line entering the equipment area, and facilitating the rapid escape of workers in emergency situations, and is suitable for industrial applications.

[0025] In one specific embodiment, the conveying assembly 20 includes two conveying tracks 201; two symmetrically arranged conveying tracks 201 are provided, and a conveyor belt 202 for conveying workpieces during rotation is provided along the length direction of the conveying tracks 201; a connecting assembly 30 is installed at the end of the conveying tracks 201 and rotatably connected to the mounting frame 10, so that the end of the conveying track 201 can rotate relative to the mounting frame 10. In this embodiment, the workpieces can be effectively transferred by the side-by-side conveying tracks 201 and the conveyor belt; the connecting assembly 30 is connected to the end of the conveying tracks 201 so that the conveying tracks 201 form a large pedestrian passage for workers to pass through when in an inclined state. Specifically, a handle 203 for lifting the conveying track 201 to open the pedestrian passage is provided on the outer side of the tail of the conveying track 201. Further, a support seat is provided on the side of the mounting frame 10 near the end of the conveying track 201 for supporting the bottom of the conveying track 201 when the conveying track 201 is kept horizontal. The support seat effectively maintains the horizontal state of the conveying track 201.

[0026] In one specific embodiment, the conveying assembly 20 further includes a first drive wheel 206, a drive shaft 204, and a geared motor 205; the first drive wheel 206 is installed at both ends of the inner side of the conveying track 201; the conveyor belt 202 is connected to the two first drive wheels 206; the drive shaft 204 is connected to the two first drive wheels 206 that are arranged opposite to each other on the two conveying tracks 201; the geared motor 205 is connected to one of the first drive wheels 206 and is used to drive the first drive wheel 206 to rotate. Specifically, the drive shaft 204 is installed at the ends of the two conveying tracks 201 and located between the two conveying tracks 201, and is connected to the two first drive wheels 206 at the ends; the output end of the reduction motor 205 is provided with a second drive wheel 207, which is connected to the first drive wheel 206 at the end of one of the conveying tracks 201 via a drive belt; during operation, the reduction motor 205 drives the second drive wheel 207 to rotate, which in turn drives the first drive wheel 206 connected to it to rotate via the drive belt. The first drive wheel 206 drives the conveyor belt 202 to rotate by cooperating with the first drive wheel 206 at the other end, and also drives the first drive wheel 206 at the end of the other conveying track 201 to rotate via the drive shaft 204, thereby driving the conveyor belt 202 of the other conveying track 201 to rotate; in this embodiment, the drive shaft 204 enables the conveyor belts 202 of the two conveying tracks 201 to rotate synchronously, thereby ensuring stable conveying of the workpiece.

[0027] In one specific embodiment, a guide plate 208 is provided on the inner side of the tail of the conveyor track 201. In this embodiment, the guide plate 208 serves a guiding function, thereby effectively ensuring that when the conveyor track 201 switches from an inclined state to a working state, the tail of the conveyor track 201 can effectively remain horizontal with other conveyor lines.

[0028] In one specific embodiment, the connecting assembly 30 includes a guide shaft 301, a first crossbeam 302, a second crossbeam 303, and a nitrogen spring 304. The guide shaft 301 is installed between two conveying rails 201 and located at the end of the conveying rails 201, with both ends of the guide shaft 301 corresponding to the conveying rails 201 and rotatably connected to the side wall of the mounting frame 10. The first crossbeam 302 is installed below the two conveying rails 201, with both ends connected to the side wall of the mounting frame 10. The second crossbeam 303 is installed between the two conveying rails 201 and connected to the two conveying rails 201, with the second crossbeam 303 and the first crossbeam 302 offset in the horizontal direction. One end of the nitrogen spring 304 is rotatably installed on the first crossbeam 302, and the other end is rotatably connected to the second crossbeam 303. In this embodiment, during operation, when the conveyor track 201 is in the working state, i.e., horizontally set, the nitrogen spring 304 contracts and stores force. When the conveyor track 201 needs to be lifted, the guide shaft 301 allows the end of the conveyor track 201 to rotate relative to the mounting frame 10. At this time, the nitrogen spring 304 is stretched and plays a supporting role. Furthermore, there are two nitrogen springs 304, which are respectively arranged adjacent to the two conveyor tracks 201. The two ends of the second crossbeam 303 are respectively provided with connecting plates 305. The two ends of the first crossbeam 302 are respectively provided with connecting seats 306. One end of the nitrogen spring is rotatably connected to the connecting plate 305, and the other end is rotatably connected to the connecting seat 306. The two nitrogen springs 304 effectively support the conveyor track 201 in the lifted state. Furthermore, the second crossbeam 303 is positioned horizontally relative to the first crossbeam 302 near the tail end of the conveyor track 201, allowing the conveyor track 201 to be effectively lifted via the guide shaft 301 at its end. Additionally, the end of the conveyor track 201 is provided with a seated bearing 307 for connecting the guide shaft 301; the inner wall of the mounting bracket 10 is provided with a guide shaft support 308 for connecting the guide shaft 301.

[0029] In one specific embodiment, the connecting assembly 30 further includes a connecting box 309, a connecting shaft 310, a handle 311, a locking rod 312, a locking shaft 313, a return spring 314, and a locking plate 315; the connecting box 309 is installed between and connected to the two conveying tracks 201; the connecting shaft 310 is installed inside the connecting box 309, with both ends extending out of the connecting box 309 and connected to the two conveying tracks 201; the handle 311 is installed on the outside of one of the conveying tracks 201 and connected to the connecting shaft 310, for driving the connecting shaft 310 to rotate; the locking rod 312 is installed inside the connecting box 309. It is located above the connecting shaft 310 and is used to swing with the rotation of the connecting shaft 310; the locking shaft 313 is installed in the connecting box 309 and is located above the connecting shaft 310, and the locking shaft 313 is provided with a guide groove for the locking rod 312 to pass through, so that when the locking rod 312 swings, it drives one end of the locking shaft 313 to extend or return to the connecting box 309; the return spring 314 is installed at one end of the locking shaft 313; when the conveying track 201 is in a horizontal state, the locking plate 315 is located on one side of the connecting box 309 and is connected to the mounting bracket 10, and the locking plate 315 is provided with a locking groove for the locking shaft 313 to engage when it extends out of the connecting box 309.

[0030] Specifically, when the conveyor track 201 is in a horizontal state, the locking shaft 313 extends out of the connecting box 309 and engages in the slot of the locking plate 315, so that the conveyor track 201 can be stably kept in a horizontal state. When it is necessary to lift the conveyor track 201, press the handle 311 to drive the connecting shaft 310 to rotate, thereby driving the locking rod 312 to swing. Through the setting of the locking rod 312 and the guide groove, the end of the locking shaft 313 is driven to disengage from the slot and return to the connecting box 309. At this time, the return spring 314 is compressed, and then the conveyor track 201 can be lifted again by the handle 203.

[0031] In one specific embodiment, the connecting assembly 30 further includes a first mounting plate 316, a second mounting plate 317, and a safety door lock. The first mounting plate 316 is mounted below and connected to the second crossbeam 303. The second mounting plate 317 is adjacent to the first mounting plate 316 and connected to the mounting frame 10. The safety door lock includes a safety door lock body 318 mounted on the second mounting plate 317 and a safety door lock key 319, corresponding to the safety door lock body 318, mounted on the first mounting plate 316. Specifically, in this embodiment, when the conveyor rail 201 is in a horizontal state, the safety door lock key 319 is locked to the safety door lock, so that the conveyor rail 201 can be horizontally limited to the mounting frame 10. When the production line is de-energized, the safety door lock opens, ensuring that in the event of an accident on the production line, workers can climb onto the conveyor rail 201 and escape through this passage.

[0032] The present invention relates to a flow channel opening and closing conveyor device, which, through the setting of mounting frame 10, conveying component 20 and connecting component 30, can form a pedestrian passage that can be passed by people as needed, providing an ideal operator direct passage solution for the conveyor belt line entering the equipment area, and facilitating the rapid escape of workers in emergency situations, and is suitable for industrial applications.
