Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices in bottle embryo cavities, in particular to a dust removal device in bottle embryo cavities. Background Art

[0002] The preform is the prototype of the plastic bottle before it is formed. It has a thick wall and high transparency. It can be sealed with a general plastic bottle cap. In addition, it is unbreakable and can stand on the table. It can be used to replace test tubes in many ways. Before the preform enters the bottle blowing machine for processing, it is necessary to remove dust and impurities inside the preform to avoid problems in subsequent work. The inverted preform is clamped from the conveyor belt by the clamping structure line, and then sent to the cleaning structure through the conveying structure. The high-pressure airflow impacts the preform cavity to complete the cleaning. Finally, the embryo cavity is placed on the conveyor belt at the rear side for subsequent work.

[0003] The clamping structure of the existing dust removal device in the bottle embryo cavity is mostly to blow high-pressure airflow into the bottom of the bottle embryo through the blowing pipe to complete the cleaning. However, the blowing pipe has a single structure and can only blow high-pressure airflow to the bottom of the bottle embryo. Then the airflow flows along the inner wall of the bottle embryo to clean the inner wall. However, the airflow at this time cannot effectively clean the plastic residue or dust adhered to the inner wall of the bottle embryo cavity, thereby affecting the cleaning effect. Therefore, we propose a dust removal device in the bottle embryo cavity to solve the above problems. Utility Model Content

[0024] The outer shell of the flushing head 5 is connected to the fixed connecting plate 4 through a sliding groove through a bottom extension block, so that the spiral blade 8 connected inside the flushing head 5 can drive the flushing head 5 to rotate when rotating, thereby driving the nozzle 6 and the brush 7 to clean the inner wall of the bottle embryo.

[0025] The nozzle 6 and the brush 7 are staggeredly distributed outside the flushing head 5, and the nozzle of the nozzle 6 faces the brushes 7 on both sides, so that the brush 7 can be cleaned by the airflow sprayed by the nozzle 6 to avoid sticking residues, and the nozzle 6 is tilted downward to guide the airflow to avoid the residues staying inside the bottle embryo due to the airflow. The inside of the nozzle 6 is arranged between the gaps of the spiral blades 8, so that enough gas can enter the nozzle 6, thereby producing a spraying effect.

[0026] A ventilation groove is provided in the fixed connecting plate 4 so that the airflow can be distributed to the flushing head 5 arranged on the fixed connecting plate 4, and the spiral blade 8 is connected to the fixed shaft 9 through a rotating shaft, so that the spiral blade 8 can drive the flushing head 5 to rotate on the top of the fixed connecting plate 4.

[0027] The clamping plates 18 form a movable structure on the clamping transverse plate 16 through the sliding groove 17, so that the size of the gap between the clamping plates 18 can be changed, thereby changing the clamping size, and the clamping plates 18 form a fixed structure with the clamping transverse plate 16 through the fixing rod 19, so that the clamping plates 18 are fixed by the fixing rod 19 and the bolts on the outside of the fixing rod 19, and the clamping plates 18 are provided with arc-shaped spring pieces, so as to squeeze and clamp the bottle embryos to improve stability.

[0028] The height of the extrusion block 20 is higher than the distance that the clamping transverse plate 16 moves on the support frame 1, so that the extrusion block 20 will not block the clamping transverse plate 16 after the clamping transverse plate 16 moves, and after the clamping transverse plate 16 moves, the extrusion block 20 will squeeze the bottle blank out of the clamping transverse plate 16 through the contraction of the second hydraulic rod 15 to realize material discharge.

[0029] The rotating shaft 14 is connected to the first hydraulic rod 2 through the connecting plate, so that the clamping cross plate 16 can move on the supporting frame 1. At the same time, the outer side of the rotating shaft 14 is connected to the motor.

[0030] Working principle: When using the dust removal device in the preform cavity, first, before working, rotate the fixed rod 19 on the outside of the clamping horizontal plate 16 to move the clamping plate 18 in the sliding groove 17 on the inside of the clamping horizontal plate 16, so that the clamping plate 18 is adjusted to the size corresponding to the preform, and then start the second hydraulic rod 15, so that the second hydraulic rod 15 drives the clamping horizontal plate 16 to squeeze downward, so that the preform is clamped by the spring sheet on the clamping plate 18, and then retract the second hydraulic rod 15;

[0031] Then, the motor outside the rotating shaft 14 at the top of the support frame 1 is started, so that the rotating shaft 14 drives the gear 13 to move in the tooth groove 12 at the top of the support frame 1, thereby driving the second hydraulic rod 15 and the clamping cross plate 16 at the bottom to move until they move to the dust box 3 and stop moving. Then, the first hydraulic rod 2 at the bottom of the dust box 3 is started, so that the dust box 3 and the fixed connecting plate 4 and the flushing head 5 inside the dust box 3 are lifted, so that the flushing head 5 enters the inside of the bottle embryo, and at the same time, the airflow is passed from the air inlet pipe 10 to the fixed connecting plate 4 through the outer pipe. Then, it enters the flushing head 5 along the airflow channel in the fixed connecting plate 4, and then passes through the spiral blade 8, so that the flushing head 5 and the spiral blade 8, which are respectively connected to the fixed connecting plate 4 and the fixed shaft 9 through the rotating shaft and the rotating slide groove, are driven by the airflow to rotate on the top of the fixed connecting plate 4, so that the nozzle 6 and the brush 7 outside the flushing head 5 clean the inside of the bottle preform, and the cleaned residue is discharged into the dust collecting box 3 for collection along the airflow and the downwardly inclined nozzle 6, and then falls into the dust collecting box 11, waiting for subsequent cleaning by the staff;

[0032] After cleaning, the first hydraulic rod 2 is retracted, so that the dust box 3 and the flushing head 5 are withdrawn from the preform, and then the motor outside the rotating shaft 14 is started, so that the second hydraulic rod 15 and the clamping cross plate 16 are moved to the lower side of the extrusion block 20 on the rear side of the support frame 1 through the tooth groove 12 and the gear 13 movable structure, and then the second hydraulic rod 15 is retracted, the clamping cross plate 16 is lifted, and the extrusion block 20 squeezes the preform clamped by the clamping plate 18, thereby completing the unloading.
