Description

Technical Field

[0001] This utility model relates to the field of filter processing technology, specifically to a drying device for spraying filter housings. Background Technology

[0002] The housing is one of the important structures in a filter. It is an external structure used to house and protect the internal components of the filter (such as capacitors, inductors, resistors, etc.).

[0003] During the manufacturing process of filter housings, in order to improve the performance of the housings, relevant performance coatings are usually sprayed onto them. When spraying the filter housings, the interface areas are usually sealed with relevant structures to prevent the coating from entering the housing through the interface and to prevent the threads and contact surfaces of the interface areas from being contaminated.

[0004] Furthermore, after the filter housing is sprayed, it is usually dried to cure the coating and prevent it from peeling off. The drying process also removes solvents and volatiles from the sprayed material.

[0005] A search revealed that patent CN220573944U discloses a drying device for spraying automotive filter housings. This patent features a vertically movable, spiral-shaped air duct inside the drying channel. During the entire filter housing spraying and drying process, the conveyor belt is intermittently opened and closed. When the conveyor belt stops, the spraying equipment inside the spraying channel sprays the filter housings that have been conveyed into the spraying channel. At this time, the drying cylinder descends under the action of a vertical electric guide rail and covers the outside of the filter housings that have been conveyed into the drying channel. The hot airflow is discharged through multiple jet holes on the spiral-shaped air duct by the cooperation of the guide sleeve and the drying cylinder.

[0006] In the prior art, when drying the filter housing, it is necessary to prevent the uncured paint on the housing surface from dripping and causing pollution to the drying equipment. Furthermore, by collecting relevant information on paint dripping, the adhesion between the paint and the housing and the drying quality can be monitored. Therefore, this utility model proposes a drying device for spraying filter housing. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-4 This utility model provides a technical solution: a drying device for spraying filter housing, including a drying box 1, a hot air assembly 2 installed on the upper side of the drying box 1, the hot air assembly 2 being used to deliver hot air into the drying box 1, and an air outlet box 3 installed on the side of the drying box 1, the air outlet box 3 being used to connect the inside of the drying box 1 with the outside, thereby playing the role of air circulation, and the air inlet of the air outlet box 3 extending into the inside of the drying box 1 and being set downwards to prevent paint from dripping into the air inlet of the air outlet box 3;

[0035] Both sides of the inside of the drying oven 1 are equipped with circulating conveyor frames 4. Multiple clamping components 5 are installed on the opposite side of the output end of the two sets of circulating conveyor frames 4. Each clamping component 5 at the output end of the two sets of circulating conveyor frames 4 is symmetrically arranged, and the two sets of clamping components 5 arranged opposite each other are used to clamp a filter housing.

[0036] Furthermore, one end of each of the two sets of circulating conveyor frames 4 extends to the outside of the drying chamber 1 to transfer the filter housing to be dried;

[0037] The clamping assembly 5 includes a movable part connected to the output end of the circulating conveyor 4, a rotating part is installed at the end of the movable part facing away from the circulating conveyor 4, and a clamping part is installed at the output end of the rotating part.

[0038] In this embodiment, the moving part adopts an electric telescopic rod structure to realize the horizontal movement of the clamping part, and the rotating part adopts a motor structure to realize the rotation of the clamping part, and the output ends of the two sets of motor structures are coaxially arranged.

[0039] The clamping position is selected based on the components that seal the filter housing interface;

[0040] In this embodiment, the filter housing is fixed by a clamp while the interface of the housing is blocked. Therefore, the clamping part adopts a robotic arm structure to clamp the clamp and move it inside the drying oven 1.

[0041] Multiple lifting components 6 are installed on both sides of the drying oven 1. The output end of each lifting component 6 faces downward and a carrier box 7 is installed between them. The carrier box 7 can slide along the bottom of the drying oven 1 under the action of each lifting component 6.

[0042] Inside the drying oven 1, an air outlet frame 10 is provided on the upper side of the two sets of circulating conveyor frames 4. The air inlet of the air outlet frame 10 is connected to the air outlet of the hot air assembly 2 through multiple connecting pipes 9.

[0043] The air outlet frame 10 includes a main pipe 101 connected to each connecting pipe 9. Both ends of the main pipe 101 are equipped with swing motors 102, and both ends of the main pipe 101 are rotatably connected to swing pipes 103. Both sets of swing pipes 103 have exhaust ports on their lower sides.

[0044] The output ends of the two sets of swing motors 102 are respectively connected to the corresponding swing tubes 103, and the connection parts of the two sets of swing motors 102 and the corresponding swing tubes 103 are distributed in the same circle as the rotation parts of the swing tubes 103 and the main tube 101.

[0045] Furthermore, both ends of the main pipe 101 are provided with communication parts between them and the two sets of swing tubes 103. When the two sets of swing tubes 103 rotate, they remain connected to the main pipe 101, thereby facilitating the discharge of hot air generated by the hot air assembly 2.

[0046] Both sets of swing tubes 103 are equipped with electric heating components to prevent heat loss of air as it flows along the connecting tube 9 and the air outlet frame 10.

[0047] The carrier box 7 is equipped with a receiving component 8. The receiving component 8 includes two sets of drive motors 81 connected to the carrier box 7. The output ends of the two sets of drive motors 81 are equipped with rotating rollers 82. The ends of the two sets of rotating rollers 82 facing away from the drive motors 81 are rotatably connected to the carrier box 7.

[0048] Two sets of rotating rollers 82 are fitted with a sleeve 83 on their outer sides. After the two sets of drive motors 81 are started, they drive the two sets of drive motors 81 to rotate in the same direction, thereby changing the part of the sleeve 83 facing the drying box 1.

[0049] Fixing components are installed on both the upper and lower sides of the sleeve 83. During use, the carrier for receiving dripping paint is fixed on the outside of the sleeve 83. In this embodiment, the carrier is a thin film with adhesive side.

[0050] The fixing component includes two sets of elastic plates 84. Both sets of elastic plates 84 are connected to the sleeve 83 through elastic elements, and with the cooperation of the elastic elements, they are attached to the outside of the sleeve 83, so as to facilitate fixing the carrier for receiving dripping paint to the outside of the sleeve 83.

[0051] Both sides of the inside of the drying chamber 1 are fixedly connected to the pressing component 11. When the receiving component 8 rises based on the lifting component 6, the bottom of the pressing component 11 presses down the carrier used to receive the dripping paint and fills the gap between the receiving component 8 and the drying chamber 1.

[0052] During operation, each clamping component 5 moves in a cycle inside the drying chamber 1 based on the circulating conveyor frame 4. When it moves to the outside of the drying chamber 1, the corresponding clamping components 5 in the two sets of circulating conveyor frames 4 are activated to clamp and fix the relevant clamps used to clamp the filter housing, and drive it into the interior of the drying chamber 1. After the filter housing enters the interior of the drying chamber 1, the rotating parts in the two sets of clamping components 5 drive the filter housing to rotate.

[0053] At the same time, the hot air assembly 2 delivers hot air to the interior of the drying chamber 1 through the connecting pipe 9 and the main pipe 101 based on the swing motor 102 to dry the filter housing, and catches the dripping paint through the film on the upper side of the sleeve 83.

[0054] When it is necessary to replace the film component, the new film component is first installed between the two sets of elastic plates 84 on the lower side of the sleeve 83. Then, each lifting component 6 is activated to lower the carrier box 7, so that the film component on the upper side is separated from the two sets of pressing components 11. Then, the two sets of drive motors 81 in the receiving component 8 drive the two sets of rotating rollers 82 to rotate, change the position of the sleeve 83, and thus move the new film component to the upward setting.

[0055] Finally, each lifting component 6 is activated again, and the receiving component 8 is moved upward through the carrier box 7, so that the two sets of pressing components 11 come into contact with the film component again.
