Description

Technical Field

[0001] The utility model relates to a transfer device, in particular to a PET bottle preform picking and transferring device, belonging to the technical field of PET bottle preform production. Background Technique

[0002] PET, fully known as polyethylene terephthalate, has a highly symmetrical molecular structure and has a certain ability of crystallization orientation, so it has a relatively high film-forming property. At the same time, PET has good optical properties and weather resistance, and amorphous PET has good transparency. In addition, PET has excellent abrasion resistance, dimensional stability and electrical insulation. Therefore, the bottles made of PET have good mechanical properties, and have the advantages of good transparency, non-toxic, anti-permeation, light weight, high production efficiency, etc., and thus are widely used. The existing PET bottle preform picking and transferring device relies on the injection molding system to provide power, that is, the picking and transferring device moves synchronously with the moving mold of the injection molding system.

[0003] However, in the existing technology, the PET bottle preforms are usually placed on the conveyor belt and transferred by the conveyor belt. When the conveyor belt is transferring, due to the small volume of the PET bottle preforms, the contact surface between their bottoms and the conveyor belt is limited, which makes the PET bottle preforms inevitably shake during the movement. If one of the PET bottle preforms topples due to shaking, all the PET bottle preforms will topple. Therefore, we propose a PET bottle preform picking and transferring device.

[0021] See also Figures 1 - 3 The utility model provides a PET preform transfer device, including a support 1 and a conveyor belt 2. A protective component 9 is arranged inside the support 1. The protective component 9 includes a plurality of placement boxes 91. Each placement box 91 is placed on the conveyor belt 2. Two annular grooves 93 are symmetrically provided inside the support 1. A plurality of sliders 92 are slidably connected inside the two annular grooves 93. One end of each slider 92 extends to the outside of the support 1. A connecting rod 94 is fixedly connected to one side of each placement box 91. A sliding rod 99 is fixedly connected to the other side of each placement box 91. Each sliding rod 99 has a One end extends to the interior of the corresponding slider 92, one end of each connecting rod 94 extends to the interior of the corresponding slider 92, each connecting rod 94 is symmetrically slidably connected to a plurality of trapezoidal blocks 96 inside, one end of each trapezoidal block 96 extends to the outside of the corresponding slider 92, each connecting rod 94 is symmetrically slidably connected to two vertical rods 97 inside, one side of each vertical rod 97 is fixedly connected to one end of the corresponding trapezoidal block 96, a plurality of springs 98 are fixedly connected inside each connecting rod 94 and between the two vertical rods 97, and a plurality of circular grooves 95 are opened inside each placement box 91.

[0022] During operation, the conveyor belt 2 rotates. Since the bottom of the placement box 91 contacts the surface of the conveyor belt 2, the friction force drives the placement box 91 to move, and the placement box 91 drives the connecting rod 94 to move. The connecting rod 94 drives the slider 92 to move, so that the slider 92 slides along the inside of the annular groove 93. At the same time, the embryo taking mechanism 8 rotates to the embryo taking position to take the embryo again. In this way, the embryo taking and conveying are carried out simultaneously, so as to avoid the PET bottle embryo from shaking or breaking due to the lack of external protection during the transportation process.

[0023] Furthermore, two cylinders 3 are symmetrically and fixedly connected to the top of the bracket 1, and connecting plates 4 are fixedly connected to the output ends of the two cylinders 3.

[0024] Furthermore, a motor 5 is fixedly connected to the top of the connecting plate 4, the output end of the motor 5 is fixedly connected to a cross bar 6, and one end of the cross bar 6 away from the motor 5 is rotatably connected to one side of the connecting plate 4.

[0025] Furthermore, two support plates 7 are symmetrically and fixedly connected to the outer wall of the cross bar 6, and a blanking mechanism 8 is fixedly connected to one side of the two support plates 7 away from the cross bar 6.

[0026] During operation, the motor 5 drives the cross bar 6 to rotate 270 degrees, the cross bar 6 drives the support plate 7 to rotate, the support plate 7 drives the blanking mechanism 8 to rotate, and then the cylinder 3 drives the connecting plate 4 to move downward, the connecting plate 4 drives the blanking mechanism 8 to move downward. When the blanking mechanism 8 is aligned with the hole of the circular groove 95, the PET bottle preform is released, and at this time, the PET bottle preform is placed inside the circular groove 95.

[0027] Furthermore, a control panel 10 is fixedly connected to the outer wall of the bracket 1, and the control panel 10 is electrically connected to the cylinder 3, the motor 5, the blanking mechanism 8 and the conveyor belt 2 respectively.

[0028] Furthermore, the inner wall of the bracket 1 is rotatably connected to the outer wall of the conveyor belt 2.

[0029] Working principle: When the blanking mechanism 8 adsorbs the PET bottle preform, the motor 5 is started. The motor 5 drives the cross bar 6 to rotate 270 degrees, the cross bar 6 drives the support plate 7 to rotate, the support plate 7 drives the blanking mechanism 8 to rotate, and then the cylinder 3 drives the connecting plate 4 to move downward, the connecting plate 4 drives the blanking mechanism 8 to move downward. When the blanking mechanism 8 is aligned with the hole of the circular groove 95, the PET bottle preform is released, and at this time, the PET bottle preform is placed inside the circular groove 95. Then the conveyor belt 2 rotates. Since the bottom of the placement box 91 is in contact with the surface of the conveyor belt 2, it will drive the placement box 91 to move under the action of friction. The placement box 91 drives the connecting rod 94 to move, and the connecting rod 94 drives the slider 92 to move, so that the slider 92 slides along the inside of the annular groove 93. At the same time, the blanking mechanism 8 rotates to the blanking position for another blanking. This process is repeated to realize simultaneous blanking and conveying, avoiding the situation of shaking and breaking of the PET bottle preform without external protection during the conveying process. Due to long-term operation, there may be dust and impurities inside the circular groove 95, and it needs to be disassembled for cleaning. At this time, the trapezoidal block 96 at one end of the connecting rod 94 is pressed. The trapezoidal block 96 presses the vertical rod 97, and the vertical rod 97 presses the spring 98, so that the trapezoidal block 96 retracts into the connecting rod 94, realizing the separation of the connecting rod 94 and the slider 92, so that the placement box 91 can be removed, facilitating the cleaning of the inside of the circular groove 95.
