When the user uses the bottle, the height of the mounting plate 42 and the screw-on strap 48 is adjusted so that the screw-on strap 48 and the top of the bottle are at the same level. When the bottle body moves between the transmitter 22 and the receiver 23 along with the conveyor belt 3, the bottle body blocks the optical signal sent by the transmitter 22, and the receiver 23 cannot receive the optical signal and then sends an electric signal to control the hydraulic rods of the two second hydraulic cylinders 41 to extend out, so that the two mounting plates 42 and the two screw-capping belts 48 are driven to move towards the mutually approaching direction, the peripheral wall of the bottle cap abuts against the two screw-capping belts 48, and the screw-capping teeth 481 of the screw-capping belts 48 are clamped on the peripheral wall of the bottle cap. The hydraulic rod of the second hydraulic cylinder 41 continues to feed, so that the screw-on strap 48 covers the peripheral wall of the bottle cap sufficiently, and in the process, the two sliding rods 44 of the same mounting plate 42 slide in the sliding grooves 43 of the mounting plate 42 in the direction of approaching each other, compressing the return spring 431. The resilience of the return spring 431 urges the slide 44 to allow the screw-on strap 48 to fit more tightly against the side of the closure. The screw-on capping belt 48 can be bent according to the volume and the shape of the bottle cap, so that the screw-on capping belt 48 can be fully attached to the peripheral wall of the bottle cap, and the screw-on capping teeth 481 on the outer side of the screw-on capping belt 48 can clamp the bottle cap, thereby being adaptive to various types of bottle caps and shortening the adaptation time. When the hydraulic cylinders of the second hydraulic cylinder 41 extend out, the receiver 23 sends out an electric signal to control all the servo motors 46 to start rotating in the same direction, the rotating shafts of the servo motors 46 drive the rotating rollers 47 to rotate so as to drive the cap screwing belts 48 to rotate, and the cap screwing belts 48 rotate to drive the cap screwing teeth 481 to move so as to drive the bottle caps to be screwed on the bottle bodies. When the bottle cap is screwed down, the torque borne by the output shaft of the servo motor 46 is increased, and at the moment, the torque sensor 49 sends an electric signal to control the hydraulic rods of the first hydraulic cylinder 21 and the second hydraulic cylinder 41 to retract, so that the arc-shaped clamp 211 is not abutted to the bottle body any more, and the cap screwing belt 48 is not abutted to the bottle cap any more; meanwhile, the torque sensor 49 sends an electric signal to control the servo motor 46 to stop rotating and control the conveyor belt 3 to start moving, thereby completing the process of screwing the cap once.

Referring to fig. 3 and 4, the top portions of the two support rods 2 are fixedly connected with a support plate 5, the support plate 5 is provided with a positioning hole 51 corresponding to the middle position of the support plate 5, the top portion of the support plate 5 is fixedly connected with a third hydraulic cylinder 52 corresponding to the positioning hole 51, a hydraulic rod of the third hydraulic cylinder 52 penetrates through the positioning hole 51 and is vertically arranged downwards, and the bottom portion of the hydraulic rod of the third hydraulic cylinder 52 is fixedly connected with a rubber pressure plate 53. Both receiver 23 and torque sensor 49 are capable of controlling the extension and retraction of third hydraulic cylinder 52.

When the user uses, when the bottle moves between transmitter 22 and receiver 23 along with conveyer belt 3, the bottle blocks the light signal that transmitter 22 sent, receiver 23 sends the pneumatic cylinder extension of signal of telecommunication control third pneumatic cylinder 52 immediately, the pneumatic cylinder of third pneumatic cylinder 52 drives rubber pressure disk 53 butt in the bottle lid top to compress tightly the bottle lid at the bottle top, play the effect of fixed bottle lid, avoid taking place to drop or the crooked not good condition of twist cap effect that causes of twist cap in the twist cap in-process bottle lid in the twist cap process. After the cap is screwed, the torque sensor 49 sends an electric signal to retract the hydraulic cylinder of the third hydraulic cylinder 52, so as to drive the rubber pressure plate 53 to be not abutted to the bottle cap, and the bottle cap and the bottle body can continuously move along with the conveyor belt 3.

The implementation principle of the novel screwing machine in the embodiment of the application is as follows: when the bottle opener is used by a user, the user places the bottle body in the arc opening of the arc baffle 31 of the conveying belt 3 and places the bottle cap at the top of the bottle body. When a user opens the conveyor belt 3, the conveyor belt 3 drives the bottles to move, when the bottles move to enter between the emitter 22 and the receiver 23, the bottles block optical signals sent by the emitter 22, the receiver 23 cannot receive the optical signals and immediately sends out electric signals to control the conveyor belt 3 to stop rotating, and meanwhile, hydraulic rods of the two first hydraulic cylinders 21 are controlled to extend out, so that the two arc-shaped clamps 211 clamp the bottles together; meanwhile, the receiver 23 controls the hydraulic rods of the two second hydraulic cylinders 41 to extend out, so that the two mounting plates 42 are driven to move towards the mutually approaching direction, the two screwing-on belts 48 fully cover the side wall of the bottle cap, and the screwing-on belt 48 between the two driven rollers 45 deforms towards the rotating roller 47, so that the screwing-on belts 48 are tightened; meanwhile, the receiver 23 controls the hydraulic rod of the third hydraulic cylinder 52 to extend out, and drives the rubber pressure plate 53 to abut against the top of the bottle cap to compress the bottle cap. Finally, the receiver 23 controls the two servo motors 46 to start rotating, the output shaft of the servo motor 46 rotates to drive the rotating roller 47 to rotate so as to drive the capping belt 48 to start rotating, the capping teeth 481 on the surface of the capping belt 48 are tightly clamped on the side wall of the bottle cap to prevent the capping belt 48 from slipping, and therefore the bottle cap is driven to rotate to screw the bottle cap. After the bottle cap is screwed down, the torque borne by the output shaft of the servo motor 46 is increased, and the torque sensor 49 sends an electric signal to control the retraction of the hydraulic rods of the two first hydraulic cylinders 21, so that the two arc-shaped clamps 211 are not abutted to the bottle body any more; simultaneously controlling the retraction of the hydraulic rods of the two second hydraulic cylinders 41 to ensure that the cap screwing belt 48 is not abutted to the bottle cap any more; and simultaneously, the hydraulic rod of the third hydraulic cylinder 52 is controlled to retract, so that the rubber pressure plate 53 is not abutted to the bottle cap any more. Finally, the torque sensor 49 controls the conveyor belt 3 to continue rotating, so that the bottle bodies are driven to continue moving along with the conveyor belt 3 and leave the screwing area, and the screwing process is completed.
