Therefore, the linear track 511 of the bottle discharging conveying track 510 is intermittently conveyed at the first speed and stopped alternately.

In order to match the requirement of continuous bottle supply for filling, the rotating speed of the dial wheel 530 is controlled, the heating seat and the plastic bottles are adjusted from a first conveying state to a second conveying state when entering the conveying curve track 512, namely, the intermittent conveying state is converted into a uniform-speed advancing state consistent with the rotating speed of the dial wheel 530, and the rotating angular speed of the dial wheel 530 is matched with the rotating angular speed of the rotating disc 541, so that the running speed of the heating seat between the rotating disc and the dial wheel is the same as the linear speed of the periphery of the rotating disc, and the heating seat can be synchronized with the rotating speed of the rotating disc so as to be accurately butted with the clamping mechanism 542 on the rotating disc. The specific rotation angular velocity of the thumb wheel and the rotating disc can be calculated according to the circumferential radius of the thumb wheel and the rotating disc and the number of the clamping mechanisms on the rotating disc.

The curve track 512 is used as a conveying state adjusting area of the heating seat and the plastic bottles, the whole length of the device can be reduced while more bottles are contained in the curve track, the plastic bottles and the heating seat are adjusted while leaving the linear track 511 under the action of the shifting wheel 530, congestion and collision of the plastic bottles at the linear track due to adjustment of the running speed are avoided, meanwhile, the rotating speeds of the rotating disc and the shifting wheel are synchronously adjusted in combination with the running speed of the linear track, the multiple groups of plastic bottles conveyed at intervals can be guaranteed to be discharged continuously, at high speed and uniformly, the linear track with overlong length is not needed to be arranged to contain redundant bottles, the occupied area of the whole device is reduced, and the conveying efficiency is improved.

In order to avoid collision caused by bottle stacking on the linear track and failure in gripping caused by misalignment of the plastic bottle and the gripping mechanism on the rotating disk, it is preferable that each bottle containing groove 532 contains 2-4 bottles, and in this embodiment, it is preferable that each bottle containing groove 532 contains 3 bottles.

The shifting teeth 531 act on the heating base during rotation to adjust the running speed of the heating base, so that the heating base and the plastic bottles carried by the heating base are consistent with the rotating speed of the shifting wheel.

In some embodiments, the curved track 512 includes a first curved section 513 and a second curved section 514 sequentially arranged along the conveying direction, and a joint of the first curved section and the second curved section is a bottle clamping station, wherein the bottle clamping station is located on a line connecting the circle centers of the dial wheel and the rotating disc 541, the circle center corresponding to the first curved section 513 coincides with the circle center of the dial wheel 530, and the circle center corresponding to the second curved section 514 coincides with the circle center of the rotating disc.

In some embodiments, an opening and closing mechanism 544 is further disposed above the rotating disc 541, as shown in fig. 5 and 9, the opening and closing mechanism 544 is fixedly connected to the workbench through a bracket, the opening and closing mechanism 544 includes a top rod 5441, and a first abutting block 5442 and a second abutting block 5443 located at two ends of the top rod 5441, and the first abutting block 5442 and the second abutting block 5443 respectively abut against the clamping mechanism 542 to open the mechanical gripper 5421 of the clamping mechanism 542.

Particularly, the action ends of the first abutting block 5442 and the second abutting block 5443, which are far away from the top rod 5441, are in a gradual curve with one side higher and the other side lower, and the distance from any point on the action ends to the center of the rotating disk gradually increases along the rotating direction of the rotating disk. Thus, the mechanical gripper 5421 can be opened and closed by the action end of the first abutting block 5442 or the second abutting block 5443 when rotating along with the rotating disk. The first abutting block 5442 is disposed on the rotating disc 541 at a position corresponding to the bottle clamping station, and particularly, a farthest end of an acting end of the first abutting block 5442 is aligned to the bottle clamping station, and the second abutting block 5443 may be used to open two jaws of a mechanical gripper when the mechanical gripper is separated from a plastic bottle.

In some embodiments, referring to fig. 7 and 8, the mechanical gripper 5421 includes a gripper base 5424, and a first gripper 5425 and a second gripper 5426 mounted on the gripper base, the first gripper 5425 and the second gripper 5426 respectively rotate around a pin, a tail end of the first gripper is connected to a tail end of the second gripper through a spring 5427, the tail end of the first gripper 5425 further includes a gripper connecting arm 5428, the gripper connecting arm 5428 is mounted with a butt 5429, and the first butt block or the second butt block movably butts against the butt to open the first gripper 5426 and the second gripper 5427.

As shown in fig. 2 and 5, the action ends of the first abutting block 5442 or the second abutting block 5443 of the opening and closing mechanism 544 abut against the abutting head 5429, and the action ends drive the abutting head 5429 to move away from the center of the rotating disc 541 along with the rotation of the rotating disc 541, so that the first clamping jaw 5426 and/or the second clamping jaw 5427 of the clamping mechanism rotate around the pin shaft to open the opening angle between the two clamping jaws, wherein when the clamping mechanism moves to the clamping station, the opening angle between the two clamping jaws reaches the maximum, the poking wheel just drives the warming seat to move the bottle just within the opening angle between the two clamping jaws, and after the abutting head 5429 leaves the position of the action end along with the further rotation of the rotating disc 541, under the action of the spring 5427, the first clamping jaw 5426 and the second clamping jaw 5427 are closed to clamp the bottle mouth of the plastic bottle, after the two sets of clamping jaws clamp the mouth of a formed plastic bottle, the sliding wheel 5423 below the mechanical clamping hand 5421 just moves from the plane area 5431 to the transition area 5433, and the mechanical clamping hand clamps the plastic bottle and lifts upwards along with the gradual increase of the surface height of the transition area 5433 until reaching the convex area 5432, so that the plastic bottle is gradually separated from the heating seat 520. Then will press from both sides through the bellying district of annular slide rail and get mechanism jack-up for the shaping plastic bottle breaks away from the seat that heats, thumb wheel and rotary disk rotate with the angular velocity that suits, make the plastic bottle press from both sides speed size and direction when getting the station and press from both sides the speed of getting the device and getting the station department the same on rotary disk, the thumb wheel of being convenient for drives the bottle and presss from both sides the mechanism butt joint of getting, effectively avoid the interference or the fish tail bottle when moving, it adopts mechanical system operation completely to go out the bottle action, can be stable, the high-speed realization goes out the bottle, avoid using the complicated control pipeline of cylinder or electric jar, when the cost is reduced, the stability of the work that also further improves.

In some embodiments, referring to fig. 4, the bottle outlet conveying track 510 includes a conveyor belt 5101, and side walls 5102 on both sides of the conveyor belt; wherein the surface friction coefficient of the conveyor belt at the first curved section 513 is lower than the surface friction coefficient of the conveyor belts of the linear track 511 and the second curved section 514. The conveyor belt 5101 of the bottle discharging conveying track 510 can be formed by splicing multiple sections of conveyor belts which are independently arranged at different positions, so that the conveyor belts at different positions can be adjusted as required.

For the straight line section and the second curve section, the heating seat is driven by the friction force between the surface of the conveying belt and the bottom of the heating seat; however, in the first curve segment, the warming seat is driven by the acting force exerted by the shifting teeth of the shifting wheel, and the friction force between the warming seat and the surface of the conveyor belt can adversely affect, for example, the overturning moment is formed between the force of the shifting teeth and the friction force to cause the toppling. By reducing the friction on the surface of the conveyor belt of the first curve section 513, the resistance of the thumb wheel during operation can be reduced, and the bottle discharging speed and stability can be improved.

Vent 5103 is filled with compressed gas. In some embodiments, the vent 5103 is communicated with the compressed air source 200 in the bottle blowing machine 1, and can share the same compressed air source with the bottle blowing forming device 400, and the existing compressed air source is used for supplying air, so that the complexity of ventilation is greatly simplified, the pipeline arrangement is optimized, and the cost is also saved.

In some embodiments, a plurality of vent holes 5103 are formed in a side wall 5102 of the first curved section 513 on a side close to the thumb wheel 530, and the vent holes 5103 are communicated with the compressed air source 200. In order to avoid the phenomenon that the heating seat is blocked during operation, the width of the transmission belt is usually slightly larger than that of the heating seat so as to operate smoothly, but the gap is too large, so that the plastic bottle and the clamping mechanism are butted in a deviation mode, and the clamping failure condition occurs. By introducing compressed air into the vent holes 5103, because the running speed of the conveyor belt and the rotating speed of the dial wheel are different, the heating seat 520 on the first curve section 513 moves relative to the conveyor belt 5101, so that a gap exists, and compressed air can be filled into the gap, so that the friction force between the heating seat 520 and the conveyor belt 5101 and the heat generated by friction are further reduced, because the heating seat 520 needs to heat bottle blanks when blowing the bottles in the bottle blowing molding device 400, and has good heat conduction performance, so that if the heat generated by friction cannot be discharged in time, the heat is conducted to the plastic bottles, particularly the bottle openings generate thermoplastic deformation, so that the rear clamping fails, meanwhile, the compressed air is blown from the dial wheel side to the rotating disc side, and the heating seat can drift to the rotating disc side when moving on the first curve section in combination with the centrifugal force generated by the heating seat when the first curve section runs, the side clearance between seat and the conveyer belt that heats just leaves the wheel side like this for the distance between seat and the rotary disk that heats can obtain more accurate control, and then realizes the plastic bottle and presss from both sides the accurate butt joint of getting the mechanism, guarantees the stability and the reliability of going out the bottle in succession.

In other embodiments, in the bottle blowing machine 10, the bottle discharge conveying rail 510 of the continuous bottle discharge device 500 is reused as a part of the rotary rail 300 for transferring bottles from the inner cavity of the bottle blowing molding device 400 to the continuous bottle discharge device 500.

Because the bottle discharging conveying track 510 is still intermittently conveyed and keeps consistent with the running mode of the rotary track 300, the bottle discharging conveying track can be directly used as a part of the rotary track, or the above embodiment of the invention can directly utilize the intermittent conveying track of the existing bottle blowing machine to realize continuous bottle discharging, thereby greatly reducing the cost and the complexity of the structure of the device and reducing the occupied area.
