Description

Technical Field

[0001] The invention relates to a preform inserting mechanism for a bottle blowing machine. Background Art

[0002] In the production process of modern bottle blowing machines, the conveying and positioning of preforms are key links. The current technical solutions usually adopt a simple conveying system, which can complete the basic conveying of preforms, but has significant defects in the following aspects:

[0003] The preform feeding mechanism in the prior art often fails to effectively constrain the angle of the preform, causing the preform to tilt or rotate when entering the bottle blowing machine. This not only affects the subsequent blow molding quality, but may also cause equipment jamming and affect production efficiency.

[0004] Many traditional preform feeding systems lack efficient sensor components and cannot accurately sense the position of the preforms, which makes the position of the preforms unstable when entering the subsequent processing links, increases the difficulty of operation, and reduces the level of automation.

[0005] In the prior art, once the preform enters the conveying channel, there is often a lack of effective limiting devices, which may cause the preform to slide or collide during the conveying process, thereby affecting the production efficiency and yield rate.

[0006] Existing systems often fail to detect the orientation of preforms in time, resulting in the preforms being oriented incorrectly when they enter subsequent processing. This not only affects product consistency, but also increases the need for manual intervention, further reducing production efficiency. Summary of the invention

[0007] The purpose of the present invention is to provide a preform feeding mechanism for a bottle blowing machine, which can significantly improve the automation level, production efficiency and product quality of the bottle blowing machine and provide an effective solution for the optimization of modern production lines.

[0028] See also Figure 1-3 As shown, a preform feeding mechanism for a bottle blowing machine includes a preform feeding groove 1 for constraining the angle of the bottle preform, a first sensor component 2 arranged at the outlet position of the preform feeding groove 1 for sensing the position of the bottle preform, a first preform feeding channel 3 arranged at the outlet position of the preform feeding groove 1, and a clamping device 4 arranged on the first preform feeding channel 3 for receiving a signal of the first sensor component 2 and limiting the bottle preform entering the first preform feeding channel 3, and a second sensor component 5 arranged at the outlet position of the first preform feeding channel 3 for sensing the direction of the bottle preform, and a bottle preform flipping mechanism 6 arranged at the outlet position of the first preform feeding channel 3 for receiving a signal of the second sensor component 5 and grasping and flipping the direction of the bottle preform, and a second preform feeding channel 7 arranged behind the bottle preform flipping mechanism 6 for conveying, grasping and flipping the bottle preform.

[0029] The preform entry groove 1 is designed to constrain the angle of the preform, ensuring that the preform enters the subsequent processing link in a correct posture, thereby improving the quality and consistency of blow molding; the first sensor component 2 is capable of sensing the position of the preform in real time, ensuring that the preform is in the correct position when entering the first preform entry channel 3, reducing processing errors caused by position deviation; the clamping device 4 can effectively receive sensor signals and limit the preform entering the channel, avoiding sliding or collision of the preform during transportation, and improving safety and stability.

[0030] The second sensor assembly 5 can detect the direction of the preform and cooperate with the flipping mechanism to ensure that the preform is in the correct direction when entering the subsequent link, thereby improving the automation level of the production process and the product qualification rate; the second preform entry channel 7 is used to transport the flipped preform, reducing the waiting time of the preform between different processes, improving the overall production efficiency, and ensuring the smooth operation of the production line; this solution reduces the dependence on manual labor through a highly automated design, reduces operational risks and human errors, and further improves production efficiency and safety.

[0031] The embryo entry trough 1 includes a trough body 11, a ramp mechanism 12 arranged in the trough body 11, a strip channel 13 arranged in the trough body 11 and adjacent to one side of the ramp mechanism 12, an inclined baffle 14 arranged on the ramp mechanism 12, and a transverse baffle 15 integrally formed with the inclined baffle 14 and located above the strip channel 13.

[0032] The combined design of the ramp mechanism 12 and the strip channel 13 enables the preform to move smoothly along a specific path, reduces the friction and resistance of the preform during the conveying process, and improves the conveying efficiency; the ramp mechanism 12 can effectively guide the preform to enter the subsequent processing link at a suitable angle, thereby reducing the jamming or tilting caused by improper angle of the preform and improving the blow molding quality; the design of the inclined baffle 14 can prevent the preform from lateral displacement in the channel, ensure the stability of the preform during the entire conveying process, and reduce the risk of accidents during the production process.

[0033] The one-piece design of the transverse baffle 15 and the oblique baffle 14 can effectively limit the movement range of the bottle preforms, avoid collision and mutual interference between the bottle preforms, and ensure that each bottle preform can pass smoothly; the one-piece design of the oblique baffle 14 and the transverse baffle 15 reduces the complexity of assembly, reduces production and maintenance costs, and improves the reliability and durability of the overall structure; this design simplifies the channel structure, facilitates cleaning and maintenance, and ensures the hygiene and stable performance of the equipment during long-term operation.

[0034] The transverse baffle 15 is provided with an opening hole 151 facing the strip channel 13 , and a rotary flap 152 for pushing back the stacked preforms is disposed at the opening hole 151 . A rotary motor 153 for controlling the rotation of the rotary flap 152 is disposed on one side of the embryo entry groove 1 .

[0035] The combined design of the opening hole 151 and the rotary flap 152 can effectively handle the stacked preforms, prevent the preforms from being blocked due to stacking, and ensure smooth flow; the setting of the rotary motor 153 enables the rotation of the rotary flap 152 to be automatically controlled, thereby improving the degree of automation of the operation, reducing manual intervention, and improving overall production efficiency.

[0036] The design of the rotary flap 152 can effectively prevent the preforms from moving backwards during the conveying process, ensuring that the preforms enter the subsequent process in the correct direction and reducing the risk of operational errors; by controlling the rotation of the flap, the preforms can be kept in a stable position in the channel, reducing the probability of collision and jamming, and ensuring the long-term stable operation of the equipment; the combination of the rotary flap 152 and the motor makes maintenance and adjustment relatively simple, which helps to improve the overall operating efficiency and service life of the equipment; this design reduces the downtime caused by preform stacking, improves the continuity and efficiency of the production line, and ensures the smoothness of the production process.

[0037] A receiving groove 31 is provided below the first embryo entry channel 3. The clamping device 4 includes a clamping arm 41 for clamping the bottle embryo, and a clamping motor 42 for controlling the clamping arm 41. The clamping arm 41 is inserted into the receiving groove 31 from below the first embryo entry channel 3 and forms a channel structure with the first embryo entry channel 3.

[0038] The clamping arm 41 can accurately clamp the preform, ensure the stability of the preform during transportation, and reduce damage or tilting caused by movement; the application of the clamping motor 42 allows the clamping process to be automatically controlled, improves the efficiency of the operation, and reduces the need for manual intervention; the clamping device 4 is designed below the first preform entry channel 3, which can effectively utilize space, optimize equipment layout, and make the production line more compact.

[0039] The combined design of the clamping arm 41 and the channel structure can realize a smooth transition of the preform from the preform entry channel to the accommodating groove 31, reducing friction and collision of the preform during transportation; through automatic clamping and smooth transition, the processing speed of the preform can be improved, ensuring the continuity and efficiency of the production process; this design simplifies the structure of the clamping device 4, facilitates daily maintenance and inspection, and improves the reliability of the equipment; automated clamping reduces the risks in the manual operation process, reduces the possibility of accidents, and ensures production safety.

[0040] The first sensor component 2 and the second sensor component 5 are both infrared laser sensors. The sensing direction of the first sensor component 2 is perpendicular to the direction of the first embryo entry channel 3 , and the sensing direction of the second sensor component 5 overlaps with the direction of the first embryo entry channel 3 .

[0041] The infrared laser sensor can provide high-precision distance and position detection, ensuring more accurate monitoring of the preforms, which helps to improve the reliability of the production process; the first sensor component 2 and the first preform entry channel 3 form a vertical direction, which can effectively monitor the lateral position of the preforms; the sensing direction of the second sensor component 5 overlaps with the channel, which can monitor the longitudinal position of the preforms in real time. This combination makes the detection of the preforms more comprehensive.

[0042] The two sensor components work together to quickly obtain the position changes of the preforms, provide timely feedback information, and help the control system make dynamic adjustments to ensure the smooth operation of the production line. Through accurate sensor data, it can effectively avoid misoperation caused by improper preform positioning, reducing the risk of equipment failure and preform damage.

[0043] Real-time monitoring of the preform status improves the safety of the system and can promptly issue alarms or stop equipment in abnormal situations to prevent accidents. Accurate sensor feedback can optimize the conveying and clamping process of the preform, reduce waiting and downtime, and thus improve overall production efficiency. Infrared laser sensors are relatively easy to integrate with existing automation systems and can be flexibly applied to different production lines to improve the scalability of the system.

[0045] The design of the first flip arm 61 and the second flip arm 62 enables the preform to be flipped in different directions, adapting to various preform shapes and requirements, and improving the flexibility of the system; by providing independent first and second flip motors 65, the flip angle and speed can be accurately controlled to ensure that the preform will not collide or tilt during the flipping process, thereby ensuring the integrity of the preform; the design of the oblique bracket 8 helps to achieve a smooth transition from the first preform entry channel 3 to the second preform entry channel 7, reducing friction and damage to the preform during the transfer process, and improving production efficiency.

[0046] The compact design of the flipping mechanism and the application of the inclined bracket 8 can optimize the space utilization, make the production line layout more reasonable, and improve the overall efficiency of the production line; the automated flipping mechanism reduces the need for manual operation, thereby reducing human errors and safety hazards during operation and improving the safety of the system; fast and accurate flipping can speed up the processing of preforms, reduce downtime, and improve overall production efficiency.
