[0011] Furthermore, both ends of one side of the conversion shell are connected with flexible tubes respectively, one end of the flexible tube away from the conversion shell is connected with a square shell, the bottom of the square shell is fixedly connected to the top of the clamp, one side of the inner wall of the square shell is connected with an air pipe, and one end of the air pipe away from the square shell is connected to one side of the inner wall of the clamping bag.

[0012] Furthermore, an auxiliary component is provided on the inner wall of the square shell, and the auxiliary component includes a piston plate slidably connected to the inner wall of the square shell, one side of the piston plate is fixedly connected to a return spring, and one end of the return spring is fixedly connected to one side of the inner wall of the square shell.

[0015] A method for using a preform mechanical lifting and flipping device comprises the following steps:

[0016] Step 1: Flipping, the transport part drives the preform to be transported, when the preform is transported to the flipping position, the transport is stopped, the forward and reverse motors are started, the forward and reverse motors drive the rotating shaft to rotate, the rotating shaft drives the cross sleeve to rotate, the cross sleeve drives the cross shell to rotate, the cross shell drives the electric telescopic rod to rotate, so that the electric telescopic rod rotates to the parallel position of the preform, the electric telescopic rod is started, the electric telescopic rod drives the concave plate to move, and is limited by the limit frame, the concave plate drives the clamping claw to rotate along the outer wall of the limit frame, the clamping claw drives the clamping capsule to rotate, and the two clamping capsules approach each other, so as to clamp the preform, and then the forward and reverse motors are flipped, and the forward and reverse motors drive the preform to flip;

[0017] Step 2: Improve the turning stability. The piston plate can drive the cross bar to move, the cross bar drives the L-shaped plate to move, the L-shaped plate drives the rotating bar to move, and the rotating bar drives the sliding part to slide along the outer wall of the vertical bar under the limitation of the vertical bar. The two sliding parts move away from each other, and the sliding part drives the universal ball to move. The universal ball slides on the outer wall of the preform part to expand the clamping range of the preform part, prevent the preform part from shaking during the turning process, and affect the turning stability of the preform part. The parking accuracy of the preform part after turning is improved;

[0018] Step 3: Improve the clamping effect. Due to the setting of the universal ball, when the universal ball slides on the side wall of the preform, because the universal ball can slide on the inner wall of the sliding part, the friction generated when the universal ball contacts the preform can be reduced, and the preform is prevented from sliding up and down when clamped by the clamping bag, and the stability of the preform flipping is further improved. When the airflow enters the interior of the square shell, when the piston plate moves to the air pipe, the airflow enters the interior of the air pipe through the setting of the air pipe, and the airflow enters the interior of the clamping bag through the air pipe, and the clamping bag is further expanded;

[0019] Step 4: Auxiliary flipping. When the preform moves to the top of the carrier, the semi-cylinder no longer contacts the bottom of the inner wall of the concave shell. Due to the elastic deformation of the spring, the spring squeezes the special-shaped plate to make the special-shaped plate slide inside the cross shell. In this process, the two cross shells can be close to each other on the outer wall of the cross sleeve. When the special-shaped plate moves to one end of the inner wall of the cross shell, the cross shell no longer slides. At this time, the cross shell will drive the preform to move on the top of the carrier, so that the preform can be accurately positioned on the top of the carrier.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, the transport member drives the preform to be transported. When the preform is transported to the flipping position, the transport is stopped, the forward and reverse motors are started, the forward and reverse motors drive the rotating shaft to rotate, the rotating shaft drives the cross sleeve to rotate, the cross sleeve drives the cross shell to rotate, the cross shell drives the electric telescopic rod to rotate, so that the electric telescopic rod rotates to a position parallel to the preform, the electric telescopic rod is started, the electric telescopic rod drives the concave plate to move, and is limited by the limit frame. The concave plate drives the clamping claw to rotate along the outer wall of the limit frame, the clamping claw drives the clamping bag to rotate, and the two clamping bags approach each other, so as to clamp the preform, and then the forward and reverse motors are turned over, the forward and reverse motors drive the preform to flip, so that the top of the preform drops to the top of the supporting platform, which is convenient for subsequent material drying.

[0022] (2) According to the present invention, when the cross shell is turned over, the cross shell drives the rotating plate to rotate, and the rotating plate drives the semi-cylinder to rotate. During the rotation of the semi-cylinder, it will come into contact with the bottom of the inner wall of the concave shell, and the reaction force of the concave shell will squeeze the semi-cylinder. The semi-cylinder drives the rotating plate to move, and is limited by the cross sleeve. The rotating plate drives the cross shell to slide along the outer wall of the cross sleeve, and the two cross shells move away from each other. During the movement of the cross shell, the airbag will be squeezed, so that the airflow inside the airbag enters the elastic tube, the airflow enters the conversion shell through the elastic tube, the airflow enters the flexible tube through the conversion shell, and the airflow enters the square shell through the flexible tube, squeezing the piston plate inside the square shell. When the piston plate moves inside the square shell, the airflow inside the square shell enters into the air pipe, and the airflow enters into the clamping bag through the air pipe to expand the clamping bag, thereby improving the clamping effect of the clamping bag on the bottle preform. In addition, the piston plate can drive the cross bar to move, the cross bar drives the L-shaped plate to move, the L-shaped plate drives the rotating bar to move, and the rotating bar drives the sliding part to slide along the outer wall of the vertical rod under the limitation of the vertical rod. The two sliding parts move away from each other, and the sliding part drives the universal ball to move. The universal ball slides on the outer wall of the bottle preform, thereby expanding the clamping range of the bottle preform, preventing the bottle preform from shaking during the flipping process, affecting the flipping stability of the bottle preform, and improving the accuracy of the parking of the bottle preform after flipping.

[0023] (3) In the present invention, due to the setting of the universal ball, when the universal ball slides on the side wall of the bottle preform, because the universal ball can slide on the inner wall of the sliding part, the friction generated when the universal ball contacts the bottle preform can be reduced, and the bottle preform is prevented from sliding up and down when clamped by the clamping bag, thereby further improving the stability of the bottle preform flipping. When the airflow enters the interior of the square shell, when the piston plate moves to the air pipe, the airflow enters the interior of the air pipe through the setting of the air pipe, and the airflow enters the interior of the clamping bag through the air pipe, further expanding the clamping bag, thereby improving the clamping effect of the clamping bag on the bottle preform and improving the stability of the bottle preform flipping.

[0024] (4) According to the present invention, when the preform moves to the top of the support platform, the semi-cylinder no longer contacts the bottom of the inner wall of the concave shell and is elastically deformed by the spring. The spring squeezes the special-shaped plate, causing the special-shaped plate to slide inside the cross shell. During this process, the two cross shells can approach each other on the outer wall of the cross sleeve. When the special-shaped plate moves to one end of the inner wall of the cross shell, the cross shell no longer slides. At this time, the cross shell drives the preform to move on the top of the support platform, so that the preform can be accurately positioned on the top of the support platform, which is convenient for the subsequent baking of the preform and further improves the accuracy of the flipping of the preform.

A clamping capsule 555 is fixedly connected to the side wall of one end of the clamping jaw 553. The side of the clamping capsule 555 away from the clamping jaw 553 contacts the outer wall of the bottle blank 4. A rotating plate 556 is rotatably connected to the side of the cross shell 54 away from the electric telescopic rod 551. The end of the rotating plate 556 away from the cross shell 54 is rotatably connected to a semi-cylinder 557.

[0046] The semi-cylinder 557 is provided with a shaped plate 558 which is slidably connected to the inner wall of the cross shell 54. A spring 559 is fixedly connected to one side of the shaped plate 558. When the preform 4 moves to the top of the supporting platform 3, the semi-cylinder 557 no longer contacts the bottom of the inner wall of the concave shell 2. The spring 559 is elastically deformed. The spring 559 squeezes the shaped plate 558 to make the shaped plate 558 slide inside the cross shell 54. In this process, the two cross shells 54 can be moved in a The outer walls of the cross sleeve 53 are close to each other. When the special-shaped plate 558 moves to one end of the inner wall of the cross shell 54, the cross shell 54 no longer slides. At this time, the cross shell 54 will drive the bottle preform 4 to move on the top of the supporting platform 3, so that the bottle preform 4 can be accurately positioned on the top of the supporting platform 3, which is convenient for the subsequent baking of the bottle preform 4.

One end of the elastic tube 562 is connected to a conversion shell 563, and the bottom of the conversion shell 563 is fixedly connected to the top of the cross shell 54.

[0048] The two ends of one side of the conversion shell 563 are respectively connected to a flexible tube 564, and the setting of the flexible tube 564 can be slightly stretched and deformed. The end of the flexible tube 564 away from the conversion shell 563 is connected to a square shell 565, and the bottom of the square shell 565 is fixedly connected to the top of the clamp 553. The inner wall of the square shell 565 is connected to an air pipe 566, and the end of the air pipe 566 away from the square shell 565 is connected to the inner wall of the clamping bag 555.

[0049] In embodiment 2, an auxiliary component 57 is provided on the inner wall of the square shell 565, the piston plate 571 can drive the cross bar 572 to move, the cross bar 572 drives the L-shaped plate 573 to move, the L-shaped plate 573 drives the rotating bar 579 to move, and is limited by the vertical rod 576. The rotating bar 579 drives the sliding member 577 to slide along the outer wall of the vertical rod 576, and the two sliding members 577 move away from each other. The sliding member 577 drives the universal ball 578 to move, and the universal ball 578 slides on the outer wall of the bottle preform 4 to expand the clamping range of the bottle preform 4, prevent the bottle preform 4 from shaking during the flipping process, and affect the flipping stability of the bottle preform 4. The side improves the accuracy of the parking of the bottle preform 4 after flipping. The auxiliary component 57 includes a piston plate 571 slidably connected to the inner wall of the square shell 565, and a return spring 575 is fixedly connected to one side of the piston plate 571.

[0050] A cross bar 572 is fixedly connected to the side of the piston plate 571 away from the return spring 575, one end of the cross bar 572 passes through the square shell 565 and extends to the outside of the square shell 565, and an L-shaped plate 573 is fixedly connected to the end of the cross bar 572 away from the piston plate 571. A square hole 574 is opened on the top of the clamp 553, and the outer wall of the bottom end of the L-shaped plate 573 is slidably connected to the inner wall of the square hole 574.

[0051] The two ends of one side of the L-shaped plate 573 are rotatably connected with a rotating bar 579, and the end of the rotating bar 579 away from the L-shaped plate 573 is rotatably connected with a sliding member 577.

Due to the setting of the universal balls 578, when the universal balls 578 slide on the side wall of the bottle preform 4, because the universal balls 578 can slide on the inner wall of the sliding member 577, the universal balls 578 can be reduced. The friction force generated when the ball 578 contacts the preform 4 prevents the preform 4 from sliding up and down when clamped by the clamping capsule 555, further improving the stability of the flipping of the preform 4. When the airflow enters the interior of the square shell 565, when the piston plate 571 moves to the air pipe 566, the airflow enters the interior of the air pipe 566 through the setting of the air pipe 566, and the airflow enters the interior of the clamping capsule 555 through the air pipe 566, further expanding the clamping capsule 555, improving the clamping effect of the clamping capsule 555 on the preform 4, and improving the flipping stability of the preform 4.

[0052] A method for using a preform mechanical lifting and flipping device comprises the following steps:

[0053] Step 1: Flipping, the transport part 1 drives the preform part 4 to be transported, when the preform part 4 is transported to the flipping position, the transport is stopped, the forward and reverse motor 51 is started, the forward and reverse motor 51 drives the rotating shaft 52 to rotate, the rotating shaft 52 drives the cross sleeve 53 to rotate, the cross sleeve 53 drives the cross shell 54 to rotate, the cross shell 54 drives the electric telescopic rod 551 to rotate, so that the electric telescopic rod 551 rotates to the parallel position of the preform part 4, the electric telescopic rod 551 is started, the electric telescopic rod 551 drives the concave plate 552 to move, and is limited by the limit frame 554, the concave plate 552 drives the clamping claw 553 to rotate along the outer wall of the limit frame 554, the clamping claw 553 drives the clamping capsule 555 to rotate, and the two clamping capsules 555 approach each other, so as to clamp the preform part 4, and then the forward and reverse motor 51 is flipped, and the forward and reverse motor 51 drives the preform part 4 to flip;

[0054] Step 2: Improve the turning stability. The piston plate 571 can drive the cross bar 572 to move. The cross bar 572 drives the L-shaped plate 573 to move. The L-shaped plate 573 drives the rotating bar 579 to move. The rotating bar 579 drives the sliding member 577 to slide along the outer wall of the vertical rod 576, and the two sliding members 577 move away from each other. The sliding member 577 drives the universal ball 578 to move. The universal ball 578 slides on the outer wall of the preform 4 to expand the clamping range of the preform 4, so as to prevent the preform 4 from shaking during the turning process, thereby affecting the turning stability of the preform 4 and improving the parking accuracy of the preform 4 after turning.

[0055] Step 3: Improve the clamping effect. Due to the setting of the universal ball 578, when the universal ball 578 slides on the side wall of the preform 4, because the universal ball 578 can slide on the inner wall of the sliding member 577, the friction generated when the universal ball 578 contacts the preform 4 can be reduced, preventing the preform 4 from sliding up and down when clamped by the clamping bag 555, further improving the stability of the flipping of the preform 4. When the airflow enters the interior of the square shell 565, when the piston plate 571 moves to the air pipe 566, the airflow enters the interior of the air pipe 566 through the setting of the air pipe 566, and the airflow enters the interior of the clamping bag 555 through the air pipe 566, and the clamping bag 555 is further expanded;

[0056] Step 4: Auxiliary flipping. When the preform 4 moves to the top of the supporting platform 3, the semi-cylinder 557 no longer contacts the bottom of the inner wall of the concave shell 2. Due to the elastic deformation of the spring 559, the spring 559 squeezes the special-shaped plate 558 to make the special-shaped plate 558 slide inside the cross shell 54. In this process, the two cross shells 54 can approach each other on the outer wall of the cross sleeve 53. When the special-shaped plate 558 moves to one end of the inner wall of the cross shell 54, the cross shell 54 no longer slides. At this time, the cross shell 54 will drive the preform 4 to move on the top of the supporting platform 3, so that the preform 4 can be accurately positioned on the top of the supporting platform 3.

[0057] During use, the transport member 1 drives the preform 4 to be transported. When the preform 4 is transported to the flipping position, the transport is stopped, and the forward and reverse motor 51 is started. The forward and reverse motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the cross sleeve 53 to rotate. The cross sleeve 53 drives the cross shell 54 to rotate. The cross shell 54 drives the electric telescopic rod 551 to rotate, so that the electric telescopic rod 551 rotates to be parallel to the preform 4. The electric telescopic rod 551 is started. The electric telescopic rod 551 drives the concave plate 552 to move. The concave plate 552 is limited by the limiting frame 554. The clamping claw 553 drives the clamping capsule 555 to rotate along the outer wall of the limiting frame 554. The clamping claw 553 drives the clamping capsule 555 to rotate. The two clamping capsules 555 approach each other, so as to clamp the preform 4. Then, the forward and reverse motor 51 is flipped. The forward and reverse motor 51 drives the preform 4 to flip, so that the top of the preform 4 drops to the top of the supporting platform 3, which is convenient for subsequent material baking.

[0058] When the cross shell 54 is turned over, the cross shell 54 drives the rotating plate 556 to rotate, and the rotating plate 556 drives the semi-cylinder 557 to rotate. During the rotation process, the semi-cylinder 557 will come into contact with the bottom of the inner wall of the concave shell 2, and the reaction force of the concave shell 2 will squeeze the semi-cylinder 557. The semi-cylinder 557 drives the rotating plate 556 to move. Limited by the cross sleeve 53, the rotating plate 556 drives the cross shell 54 to slide along the outer wall of the cross sleeve 53, and the two cross shells 54 move away from each other. During the movement of the cross shell 54, the airbag 561 is squeezed, so that the airflow inside the airbag 561 enters the interior of the elastic tube 562, the airflow enters the interior of the conversion shell 563 through the elastic tube 562, the airflow enters the interior of the flexible tube 564 through the conversion shell 563, and the airflow enters the interior of the square shell 565 through the flexible tube 564, and squeezes the piston plate 571 inside the square shell 565. When the plate 571 moves inside the square shell 565, the airflow inside the square shell 565 enters into the air pipe 566, and the airflow enters into the clamping bag 555 through the air pipe 566, so that the clamping bag 555 expands, thereby improving the clamping effect of the clamping bag 555 on the bottle preform 4, and the piston plate 571 can drive the cross bar 572 to move, the cross bar 572 drives the L-shaped plate 573 to move, and the L-shaped plate 573 drives the rotating bar 579 to move. Limited by the vertical rod 576, the rotating bar 579 drives the sliding member 577 to slide along the outer wall of the vertical rod 576, and the two sliding members 577 move away from each other. The sliding member 577 drives the universal ball 578 to move, and the universal ball 578 slides on the outer wall of the bottle preform 4, thereby expanding the clamping range of the bottle preform 4, preventing the bottle preform 4 from shaking during the flipping process, affecting the flipping stability of the bottle preform 4, and improving the accuracy of the parking of the bottle preform 4 after flipping.

[0059] Due to the setting of the universal ball 578, when the universal ball 578 slides on the side wall of the bottle preform 4, because the universal ball 578 can slide on the inner wall of the sliding member 577, the friction generated when the universal ball 578 contacts the bottle preform 4 can be reduced, and the bottle preform 4 is prevented from sliding up and down when clamped by the clamping bag 555, and the stability of the bottle preform 4 is further improved. When the airflow enters the interior of the square shell 565, when the piston plate 571 moves to the air pipe 566, the airflow will enter the interior of the air pipe 566 through the setting of the air pipe 566, and the airflow enters the interior of the clamping bag 555 through the air pipe 566, further expanding the clamping bag 555, thereby improving the clamping effect of the clamping bag 555 on the bottle preform 4 and improving the stability of the bottle preform 4.

[0060] When the preform 4 moves to the top of the supporting platform 3, the semi-cylinder 557 no longer contacts the bottom of the inner wall of the concave shell 2, and is elastically deformed by the spring 559. The spring 559 squeezes the special-shaped plate 558 to make the special-shaped plate 558 slide inside the cross shell 54. In this process, the two cross shells 54 can approach each other on the outer wall of the cross sleeve 53. When the special-shaped plate 558 moves to one end of the inner wall of the cross shell 54, the cross shell 54 no longer slides. At this time, the cross shell 54 will drive the preform 4 to move on the top of the supporting platform 3, so that the preform 4 can be accurately positioned on the top of the supporting platform 3, which is convenient for the subsequent baking of the preform 4 and further improves the turning accuracy of the preform 4.
