The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1, 2, 3 and 7, the invention provides a continuous conveying channel for preventing plastic bottles from being blocked, which comprises a top support 10 and a top plate 20, wherein the top support 10 and the top plate 20 enclose an air draft channel 12, the top plate 20 is provided with a bottle mouth support 21 extending into the air draft channel 12, the side surface of the bottle mouth support 21 is provided with a ventilation opening 22 communicated with the air draft channel 12, two bottle mouth support guide rails 30 which are parallel to each other are arranged below the bottle mouth support 21, each bottle mouth support guide rail 30 is provided with a wedge-shaped protrusion 31 for supporting a bottle mouth 3 of a bottle body 1, the two side edges of the top support 10 extend downwards to form side plates 13, the side plates 13 are provided with anti-blocking clamping jaws 72 pointing to necks 2 of the bottle bodies 1, and gaps 73 are formed between the anti-blocking clamping jaws 72 and the necks 2 of the bottle bodies 1.

As shown in fig. 4, the continuous conveying path for preventing the plastic bottles from being blocked is mainly used for continuously conveying the bottle bodies 1, wherein the bottle bodies 1 comprise necks 2 and bottle openings 3, and the widths of the necks 2 are gradually increased from the bottle openings 3 downwards. Bottle 1 is at the transportation process, and the air current blows bottle 1 between the curb plate 13 of both sides, and bottle 1's bottleneck 3 supports on bottleneck support guide rail 30's wedge protrusion 31, and bottle 1's bottleneck 3 moves along bottleneck support guide rail 30 forward, and the air current enters into convulsions passageway 12 through the vent 22 of bottleneck support 21 in, and the rethread convulsions passageway 12 is discharged or the circulation is blown.

Two bottleneck support guide rail 30 parallel arrangement, the wedge protrusion 31 of two bottleneck support guide rail 30 sets up in opposite directions, the most advanced support of two wedge protrusions 31 is in the bottleneck 3 below of bottle 1, because bottleneck 3 most of have the circular structure of boss, so long as adjust the distance between the most advanced of two wedge protrusions 31 and be less than the boss of bottleneck 3 slightly, bottleneck 3 just can not drop from bottleneck support guide rail 30, when blowing to bottle 1 like this, bottleneck 3 of bottle 1 just can slide along bottleneck support guide rail 30 forward, and then realize the continuous conveyor of bottle 1.

The side plates 13 are provided with anti-blocking clamping jaws 72 pointing to the neck 2 of the bottle body 1, each side plate 13 is provided with one anti-blocking clamping jaw 72, and the anti-blocking clamping jaws 72 on the side plates 13 at both sides can be arranged into a symmetrical structure. When the bottle body 1 is normally conveyed, a gap 73 is formed between the anti-blocking clamping jaw 72 and the neck 2 of the bottle body 1, and the gap 73 can ensure that the bottle body 1 cannot collide with the anti-blocking clamping jaw 72 when moving. When the air flow fluctuates, the bottle bodies 1 collide with each other and squeeze each other, so that part of the bottle bodies 1 move upwards, the bottle mouths 3 of the bottle bodies 1 move towards the bottle mouth supports 21 due to the restriction of the bottle mouth supporting guide rails 30, and the positions, closest to the bottle mouths 3, on the necks 2 of the bottle bodies 1 also move upwards along with the bottle mouths 3. Since the neck 2 of some plastic bottles is relatively slender, if not blocked by the anti-blocking jaws 72, the neck 2 of the bottle body 1 will partially pass through the two wedge-shaped projections 31 until the bottle body 1 will no longer move upward when the mouth 3 of the bottle body 1 abuts against the uppermost end of the mouth support 21. If the bottle bodies 1 are continuously extruded by collision, the bottle bodies 1 are inclined, and the neck parts 2 of the bottle bodies 1 partially penetrate through the wedge-shaped protrusions 31 to enter the bottle opening supports 21, so that the bottle bodies 1 can be inclined at a large angle, and once one bottle body 1 is inclined at a large angle during continuous conveying, the adjacent bottle bodies are also inclined, and finally the conveying passage is blocked. This application adopts the design of preventing stifled clamping jaw 72, when the neck 2 of bottle 1 begins the rebound, because neck 2 when shifting up and prevent that the clearance 73 between the stifled clamping jaw 72 constantly reduces, final neck 2 will receive preventing stopping of preventing stifled clamping jaw 72 and can't continue to shift up, as long as the length that the neck 2 of bottle 1 passed wedge protrusion 31 is not big, so bottle 1 just can not take place the large angle slope, just so can not take place the problem that transfer passage blockked up.

As shown in fig. 5 and 6, in some plastic bottles, the neck 2 is elongated, and when the mouth 3 of the bottle body 1 moves into the mouth holder 21, the mouth 3 can abut against the uppermost end of the mouth holder 21, so that a spacer 50 can be provided inside the mouth holder 21. The insert 50 reduces the space within the mouth support 21, which reduces the distance that the mouth 3 of the bottle body 1 moves into the mouth support 21 and, correspondingly, reduces the distance that the neck 2 of the bottle body 1 penetrates the wedge-shaped projection 31 and enters the mouth support 21.

The base plate 50 needs to be fixed to the top surface inside the bottle mouth support 21, the inner space of the bottle mouth support 21 is small, the base plate 50 is convenient to be installed inside the bottle mouth support 21, the base plate 50 and the bottle mouth support 21 can be connected through the elastic part 60, the elastic part 60 can be a torsion spring, a clamp spring or an elastic sheet and other fixing structures with elasticity, and therefore the base plate 50 can be conveniently clamped inside the bottle mouth support 21 through the elastic part 60.

In the scheme, the movable clamping jaw 723 can rotate through the hinged shaft 724, the spring 727 sleeved outside the clamping jaw guide column 725 during rotation of the movable clamping jaw 723 can play a role in elastic support, the rotating sleeve 726 can be in threaded connection with the clamping jaw guide column 725, and after the rotation angle of the movable clamping jaw 723 is adjusted, the rotating sleeve 726 is screwed down to press the movable clamping jaw 723 onto the spring 727. The bottle bodies 1 of different specifications can be adapted by adjusting the rotation angle of the movable clamping jaw 723.

In the above scheme, the side plate 13 is provided with a height adjusting mechanism for adjusting the height of the mechanical driving mechanism 70, the height adjusting mechanism includes a driving motor 80 and a sliding block 81 connected with the driving motor 80, and the sliding block 81 is connected with the mechanical driving mechanism 70 through a connecting plate 82. The height adjusting mechanism can be manually adjusted in a manual mode, and can also be automatically adjusted through a mechanical structure. For example, a mechanical structure driven by the driving motor 80 may be adopted, the driving motor 80 drives the sliding block 81 to move up and down, and the sliding block 81 drives the mechanical driving mechanism 70 to adjust the height through the connecting plate 82. The movement of the slider 81 can be controlled by the driving motor 80 and the slider 81 through a screw transmission.

The height adjusting mechanism is designed so that when the bottle bodies 1 of the plastic bottles incline in the conveying channel, the bottle bodies 1 are directly righted through the height adjustment of the height adjusting mechanism, and the specific operation steps are as follows: when the bottle body 1 inclines, the mechanical driving mechanism 70 on the side plates 13 at two sides is started, the telescopic rod 71 is controlled to extend or contract the anti-blocking clamping jaw 72, when the gap 73 between the anti-blocking clamping jaw 72 and the neck 2 of the bottle body 1 is just larger than the maximum width of the bottle body 1, the telescopic rod 71 is stopped, the driving motor 80 is started to enable the sliding block 81 to move downwards, the sliding block 81 drives the mechanical driving mechanism 70 to move downwards through the connecting plate 82, the clamping jaw 723 and the soft blocking piece 722 of the anti-blocking clamping jaw 72 can move along with the bottle body 1 in the downward moving process of the mechanical driving mechanism 70, and the clamping jaw 723 and the soft blocking piece 722 can centralize the inclined bottle body 1 in the moving process. After the bottle body is righted, the driving motor 80 is controlled to rotate reversely, so that the sliding block 81 moves upwards, the sliding block 81 drives the mechanical driving mechanism 70 to return to the initial position through the connecting plate 82, and then the gap 73 between the anti-blocking clamping jaw 72 on the mechanical driving mechanism 70 and the neck 2 of the bottle body 1 is restored to the initial width.

The air suction opening 11 is used for discharging or recycling air in the air suction channel 12 to the outside, and the position of the height adjusting mechanism corresponds to the air suction opening 11, because the air flow fluctuation at the position of the air suction opening 11 is large, the problem that the bottle body 1 is inclined and blocked easily occurs at the position of the air suction opening 11 when the bottle body 1 is continuously conveyed, and therefore, the height adjusting mechanism is more necessary to be arranged at the position of the air suction opening 11. Meanwhile, a top reinforcing plate 90 is provided on the top plate 20, and the position of the top reinforcing plate 90 also corresponds to the suction opening 11. The top stiffener 90 serves two purposes: first, the structural strength of the top plate 20 can be improved; secondly, the elastic component 60 at the suction opening 11 can be protected, and the elastic component 60 is prevented from loosening due to the fact that the wind speed at the suction opening 11 is high. The top reinforcing panel 90 and the top panel 20 may be connected by reinforcing plate fasteners 24.

Guide rail mounting grooves 32 are formed below the mouthpiece support guide rail 30, a guide rail bracket 40 for fixing the mouthpiece support guide rail 30 is formed below the top plate 20, and a guide rail bracket flange 41 fitted to the guide rail mounting grooves 32 is formed at one end of the guide rail bracket 40. The rail bracket 40 engages the support rail 30 below the top plate 20 via a rail bracket flange 41, and the rail bracket 40 is connected to the top plate 20 via a rail bracket fastener 23.

The top support 10 and the top plate 20 may be connected by top plate fasteners 25, and the top support 10 and the side plates 13 may be connected by side plate fasteners 26.
