Abstract
Description
Technical Field
[0001] This utility model relates to the field of blow molding technology, and in particular to a dust removal and turning device. Background Technology
[0002] In the field of blow molding production, the preform is the core raw material of the blow molding process, and its internal cleanliness directly determines the quality of subsequent blow molding and the safety of the filling process. In the process before heating the blow molding, the dust and impurities inside the preform must be thoroughly removed. If the dust removal is not thorough, it will lead to quality problems such as surface defects and uneven wall thickness in the blow-molded bottle, affecting the product qualification rate. On the other hand, the residual impurities may contaminate the contents during the subsequent filling process, causing food safety risks or product scrapping, resulting in economic losses for the company.
[0003] Currently, the mainstream dust removal method for bottle preforms in the industry is a "preform opening upward, electrostatic air outlet downward blowing" structure. This structure can barely meet the basic requirements for dust removal of short-sized bottle preforms, but it has certain shortcomings when dealing with long-sized bottle preforms: due to the long internal cavity of long bottle preforms, the downward blowing airflow in a fixed direction cannot cover the entire cavity, which easily forms a dead airflow at the bottom of the bottle preform, resulting in the accumulation and residue of dust and debris, and unstable dust removal effect; at the same time, existing devices mostly rely on solenoid valves to control the air outlet angle, which not only requires additional configuration of solenoid valves and corresponding control circuits, increasing the equipment manufacturing cost and maintenance difficulty, but also the response delay of solenoid valves can easily cause the airflow to be out of sync with the movement of the bottle preform, which may reduce the dust removal efficiency and consistency.
[0004] In addition, existing dust removal devices lack an active adjustment mechanism for the preform's posture. The preform always maintains a fixed angle to receive air, and cannot adjust its posture to allow internal debris to be drawn towards the air outlet by gravity, which may exacerbate the problem of incomplete dust removal. Utility Model Content
[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a dust removal and turning device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dust removal and turning device, comprising: Frame, turntable, nozzle guide rail, support column, nozzle, flip gripper, outer guide column, gripper flip rail, fixed gripper, rotary air distributor and fixed air rotating body; The fixed gas rotating body is fixedly installed on the frame, and the rotary gas distributor is rotatably engaged with the fixed gas rotating body. The fixed gas rotating body can deliver gas into the rotary gas distributor at a fixed angle. The turntable is rotatably mounted on the frame, and the fixed gripper is fixedly mounted on the turntable; the fixed gripper is provided with a rotating shaft, and the flipping gripper is rotatably connected to the fixed gripper through the rotating shaft; One end of the outer guide post is fixedly installed on the outer side wall of the flip gripper. The gripper flipping guide rail is fixed on the frame and slides in cooperation with the other end of the outer guide post, so as to control the rotation angle of the flip gripper around the rotating shaft by the sliding trajectory of the outer guide post. The nozzle guide rail is fixed on the frame and located on the side of the turntable. One end of the support column slides in cooperation with the nozzle guide rail, and the other end of the support column is fixedly connected to the nozzle. The nozzle is connected to the rotary gas distributor through an air pipe to receive the gas delivered by the rotary gas distributor and blow gas onto the preform.
[0007] Preferably, the mouthpiece guide rail is an arc-shaped guide rail, and the end of the support column that cooperates with the mouthpiece guide rail is provided with a slider. The slider is embedded in the groove of the arc-shaped guide rail and slides along the groove.
[0008] Furthermore, the flip-gripper is provided with a clamping part on the side away from the outer guide post. The clamping part is an arc-shaped groove structure, and the inner wall of the arc-shaped groove is provided with anti-slip texture to stabilize the bottle preform.
[0009] Preferably, the support column and the mouthpiece are detachably connected. The top end of the support column is provided with an internal threaded hole, and the bottom end of the mouthpiece is provided with an external threaded section. The external threaded section is threadedly engaged with the internal threaded hole.
[0010] Compared with the prior art, the present invention provides a dust removal and turning device, which has the following beneficial effects: This invention utilizes a structure of "flipping gripper + outer guide post + gripper flipping guide rail" to precisely control the flipping angle of the preform. When the outer guide post slides along the preset trajectory of the gripper flipping guide rail, it drives the flipping gripper to rotate around the axis of the fixed gripper, allowing the preform to adjust to the optimal dust removal posture according to the internal cavity structure. Combined with the directional blowing of the nozzle, it effectively eliminates the airflow dead zone at the bottom of long preforms, ensuring that dust and debris are completely discharged under the combined action of airflow and gravity. At the same time, the arc-shaped nozzle guide rail drives the support column and nozzle to adjust their directions synchronously through the slider, always maintaining the precise alignment between the nozzle and the preform opening, avoiding dust removal omissions caused by airflow deviation. It can achieve a consistent and efficient dust removal effect for both short and long preforms.
[0011] This utility model adopts a gas conveying structure of "fixed gas rotating body + rotary gas distributor": the fixed gas rotating body directly limits the direction of gas entering the rotary gas distributor through its own fixed angle orifice, without the need for additional solenoid valves and control circuits. This not only reduces the number of core components of the equipment, lowers manufacturing and procurement costs, but also avoids wear and failure problems caused by long-term high-frequency operation of solenoid valves, reduces the number of equipment downtime maintenance and maintenance costs, and extends the overall service life of the equipment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Example 1
[0016] Reference Figures 1-4 A dust removal turning device includes a frame, a turntable, a nozzle guide rail 1, a support column 2, a nozzle 3, a turning gripper 4, an outer guide column 5, a gripper turning guide rail 6, a fixed gripper 7, a rotary air distribution body 8, and a fixed air rotating body 9. The fixed gas rotating body 9 is fixedly installed on the frame, and the rotary gas distributor 8 is rotatably engaged with the fixed gas rotating body 9. The fixed gas rotating body 9 can deliver gas to the rotary gas distributor 8 at a fixed angle. The turntable is rotatably mounted on the frame, and the fixed gripper 7 is fixedly mounted on the turntable; the fixed gripper 7 is provided with a rotating shaft, and the flip gripper 4 is rotatably connected to the fixed gripper 7 through the rotating shaft; One end of the outer guide post 5 is fixedly installed on the outer side wall of the flip gripper 4. The gripper flip guide rail 6 is fixed on the frame and slides with the other end of the outer guide post 5 to control the rotation angle of the flip gripper 4 around the rotating axis through the sliding trajectory of the outer guide post 5. The nozzle guide rail 1 is fixed on the frame and located on the side of the turntable. One end of the support column 2 slides with the nozzle guide rail 1, and the other end of the support column 2 is fixedly connected to the nozzle 3. The nozzle 3 is connected to the rotary gas distributor 8 through the air pipe to receive the gas delivered by the rotary gas distributor 8 and blow gas onto the preform 10.
[0017] The mouthpiece guide rail 1 is an arc-shaped guide rail. The end of the support column 2 that mates with the mouthpiece guide rail 1 is provided with a slider. The slider is embedded in the groove of the arc-shaped guide rail and slides along the groove.
[0018] The flip-grip 4 has a clamping part on the side away from the outer guide post 5. The clamping part has an arc-shaped groove structure, and the inner wall of the arc-shaped groove has anti-slip texture to stabilize the bottle preform 10.
[0019] The support column 2 and the mouthpiece 3 are detachably connected. The top of the support column 2 is provided with an internal threaded hole, and the bottom of the mouthpiece 3 is provided with an external threaded section. The external threaded section is threadedly engaged with the internal threaded hole.
[0020] Reference Figures 1-4 When in use, start the drive assembly to make the turntable start to rotate at a constant speed around the rotation center on the frame; since the fixed gripper 7 is fixedly installed on the turntable, the turntable will synchronously drive the fixed gripper 7, the flip gripper 4 connected to the fixed gripper 7 through the rotating shaft, and the preform 10 that moves synchronously with the flip gripper 4 to rotate. As the turntable moves the flip gripper 4, the other end of the outer guide post 5, which is fixed to the outer wall of the flip gripper 4, slides along the gripper flip guide rail 6, which is fixed to the frame. The preset trajectory of the gripper flip guide rail 6 guides the outer guide post 5 to move along the path. The outer guide post 5 then drives the flip gripper 4 to rotate around the pivot on the fixed gripper 7, so as to achieve precise control of the flip angle of the flip gripper 4 and the bottle preform 10 it holds, ensuring that the bottle preform 10 is in a position that is easy to remove dust. As the turntable rotates, the slider at one end of the support column 2, which moves synchronously with the turntable, slides along the groove of the arc-shaped nozzle guide rail 1, which is fixed to the frame and located on the side of the turntable. The arc-shaped trajectory of the nozzle guide rail 1 controls the rotation direction of the support column 2, so that the nozzle 3, which is fixedly connected to the support column 2, adjusts its direction synchronously and is always aligned with the bottle preform 10 to be removed from dust.
[0021] Meanwhile, the fixed air rotating body 9 delivers gas at a fixed angle to the rotating air distribution body 8, and the rotating air distribution body 8 then delivers the gas to the nozzle 3 through the air pipe; after receiving the gas delivered by the rotating air distribution body 8, the nozzle 3 blows air into the bottle preform 10 which is in a specific flipping posture, and uses the airflow to blow out the dust and debris inside the bottle preform 10, thus completing the dust removal operation of the bottle preform 10. When the turntable completes one revolution of the preform 10 and the dust removal operation is finished, turn off the drive assembly to stop the turntable from rotating and return all parts to their initial positions; release the gripping part of the flipping gripper 4 and take out the preform 10 that has been dusted.
