Description

Technical Field

[0001] This utility model relates to a blowing device for the shell and core of an automatic shell assembly unit. Background Technology

[0002] In the field of precision manufacturing, the cleanliness of the shell and core surfaces directly affects product performance and reliability.

[0003] Traditional purging processes rely on manual operation of handheld air guns, resulting in low efficiency, inconsistent performance, and safety hazards. To overcome this technological bottleneck, we have developed an automated purging device integrating a sealed tank, air knife, clamping mechanism, and hollow rotating platform. Through optimized airflow dynamics and mechanical coordination, it achieves efficient and precise surface cleaning. In traditional purging processes, manual operation is limited by operator skill and fatigue, and the purging pressure, angle, and coverage area are difficult to standardize, leading to fluctuating cleaning results. For example, complex curved surfaces or hard-to-reach areas are prone to particulate residue.

[0004] This requires repeated re-blowing, significantly reducing production efficiency and posing safety and cost risks. When operating a high-pressure air gun, flying particles can damage the operator's eyes or respiratory tract, and prolonged exposure to noise can lead to occupational health risks. Manual purging requires protective equipment, increasing operating costs for businesses.

[0005] In addition, manual cleaning is not suitable for environments requiring high cleanliness, nor is it suitable for the working requirements of dark factories. Utility Model Content

[0006] In order to overcome the shortcomings of the current method of cleaning the surface of the shell and core by manually holding an air gun, this utility model provides a blowing device for the shell and core.

[0007] The technical solution of this utility model to solve its technical problem is as follows: a purging device for a shell and core, comprising a container with an opening at the top and a sealed container lid, a seat on the bottom plate of the container, a rotatable rotating seat on the seat, a gear ring below the rotating seat, a rotating motor on the bottom plate, and an output gear of the rotating motor extending above the bottom plate and meshing with the gear ring of the rotating seat for transmission; a clamping cavity in the middle of the rotating seat, and a rotating ring that can rotate relative to it in the middle of the rotating seat; and several clamping claws, each clamping claw having a first connecting end and a second connecting end, the first connecting end being connected to the rotating ring, and the second connecting end being connected to the rotating seat. When the moving ring rotates relative to the rotating seat, it causes the clamping claws to move into or away from the clamping cavity. A drive spring is also provided between the moving ring and the rotating seat, ensuring that the moving ring drives the clamping claws to the clamping position under normal conditions. A drive handle is also provided on the outside of the moving ring, and a drive wedge is provided on the base plate. A lifting cylinder is provided below the drive wedge. When the lifting cylinder drives the drive wedge upward, the drive wedge pushes the drive handle against the moving ring, thus releasing the clamping claws on the moving ring. A purging mechanism is also provided on the side of the rotating seat inside the container. The purging mechanism includes an air knife nozzle and an external air supply pipe connecting to the air knife nozzle. The air nozzle's nozzle is aligned with the rotating seat. An exhaust port is also provided on the container. Preferably, the exhaust port is located on the base plate.

[0008] To facilitate the installation of the motor and lifting cylinder, a lower compartment is provided below the container, and the rotating motor and lifting cylinder are located in the lower compartment.

[0009] To improve the purging effect, the purging mechanism is equipped with three sets of air knife nozzles, which are mounted on the air knife stand surrounding the rotating seat.

[0010] Furthermore, a set of air knife nozzles includes an upper air knife nozzle and a lower air knife nozzle. The upper air knife nozzle is installed on the upper part of the air knife stand and the air outlet direction is obliquely downward. The lower air knife nozzle is installed on the lower part of the air knife stand and the air outlet direction is obliquely upward.

[0011] To improve the cleanliness of the environment inside the container, the air knife stand is also equipped with a side spray dust removal head, which is connected to a high-pressure water pipeline and can spray and settle dust in the air during the purging process.

[0012] Furthermore, a main spray dust removal head is provided below the rotating seat. The main spray dust removal head is fixed on the base plate with its head facing upward and aligned with the clamping cavity. The main spray dust removal head is connected to a high-pressure water pipeline.

[0013] A preferred embodiment of a clamping claw is wherein the head of the clamping claw is used for clamping, a first connecting end is located outside the root of the clamping claw, and a second connecting end is located inside the root of the clamping claw.

[0014] Furthermore, the first connecting end is a stroke groove, in which a connecting rod is provided, the lower end of which is fixed to the moving ring; the second connecting end is a hinge shaft, the other end of which is fixed to the rotating seat.

[0015] A preferred method for mounting the drive spring and drive handle is provided, wherein the rotating base has a spring groove and a drive handle groove, the drive spring is located in the spring groove, the drive handle is located in the drive handle groove, and the drive handle can move within the drive handle groove.

[0016] In a preferred embodiment of a sealing container lid structure, a lid-closing cylinder for driving the opening and closing of the sealing container lid is provided on one side of the sealing container lid.

[0017] In use, this invention uses a closing cylinder to open the sealing container lid, exposing the opening at the top of the container. A lifting cylinder then moves the drive wedge upwards, pushing the drive handle against the rotating ring. This releases the gripping claws on the rotating ring, preparing it for the placement of the shell or core to be cleaned. The robotic arm places the shell or core requiring surface cleaning into the gripping cavity of the rotating seat. At this point, the lifting cylinder retracts, the wedge moves downwards, and due to the action of the drive spring, the rotating ring and rotating seat reset, causing the gripping claws to pop out and secure the workpiece.

[0018] The cylinder drives the sealing container lid to close, sealing the container and preventing dust from escaping during the purging process.

[0019] Then the purging stage begins. During the purging stage, the air supply line delivers high-pressure gas to the air knife nozzle. The high-pressure gas purifies the workpiece, and at the same time, the rotating motor is turned on. The output gear of the rotating motor meshes with the gear ring under the rotating seat, driving the rotating seat to rotate, causing the shell and core to rotate accordingly, so that purging can be carried out in all directions.

[0020] During the purging process, both the side spray dust removal head and the main spray dust removal head are turned on simultaneously. Water is supplied through a high-pressure water pipeline, causing the spray dust removal head to spray out a mist of water, which settles the dust in the air and improves the cleanliness of the environment inside the container.

[0021] After purging is completed, first stop the external air supply line to supply air to the air knife nozzle and close the air knife nozzle; then stop the rotating motor to stop the rotating seat from rotating.

[0022] The lifting cylinder drives the drive wedge to move upward, and the drive wedge pushes the drive handle and the moving ring, so that the clamping claws on the moving ring are in the loosened position, releasing the clamping of the housing and core.

[0023] Finally, the cylinder closes and opens the sealed container cover. The robotic arm then reaches in and removes the cleaned shell and core from the gripping cavity of the rotating seat, completing the operation.

[0024] The beneficial effects of this utility model are as follows: 1. The automated blowing device reduces manual intervention, eliminates the need for additional protective equipment, and lowers the company's operating costs. The device integrates a sealed tank, air knife, clamping mechanism, and hollow rotating platform, and is optimized through airflow dynamics and mechanical coordination. During the blowing stage, the rotating motor drives the rotating seat to rotate, causing the shell and core to rotate accordingly. Simultaneously, three sets of air knife nozzles surround the rotating seat, enabling comprehensive, efficient, and precise surface cleaning of the workpiece from multiple angles. This avoids the fluctuations in cleaning effect caused by the difficulty in standardizing pressure, angle, and coverage area in traditional manual blowing, effectively removing particles that are easily retained in complex curved surfaces or dead-angle areas. 2. The air knife stand is equipped with a side spray dust removal head, and a main spray dust removal head is located below the rotating seat. During the blowing process, water is supplied through a high-pressure water pipeline, causing the spray dust removal head to spray a mist of water, which can settle dust in the air, greatly improving the cleanliness of the environment inside the container and meeting the requirements of production environments with high cleanliness requirements. 3. Because it is equipped with three sets of air knife nozzles, and each set of air knife nozzles includes an upper air knife nozzle and a lower air knife nozzle, their air outlet directions are different, which can blow the workpiece surface from multiple angles and improve the cleaning effect.

[0034] To facilitate the installation of the motor and the lifting cylinder 19, a lower chamber 23 is provided below the container 3, and the rotating motor 9 and the lifting cylinder 19 are located in the lower chamber 23.

[0035] To improve the purging effect, the purging mechanism 20 is equipped with three sets of air knife nozzles 21, which are mounted on the air knife stand 24 surrounding the rotating seat 7.

[0036] Combined with appendix Figure 4 A set of air knife nozzles 21 includes an upper air knife nozzle 25 and a lower air knife nozzle 26.

The lower air knife nozzle 26 is installed on the lower part of the air knife stand 24 and the air outlet direction is obliquely upward.

[0037] In order to improve the cleanliness of the environment inside the container 3, the air knife stand 24 is also equipped with a side spray dust removal head 27.
