Description

Technical Field

[0001] This utility model belongs to the field of filter technology, and in particular relates to an anti-loosening structure for bending filter paper in automotive air conditioning filters. Background Technology

[0002] An automotive air conditioning filter is a filter specifically designed for purifying the air inside a car. It can filter impurities, fine particles, pollen, bacteria, industrial exhaust gases, and dust from the air, thereby providing a good air environment inside the car, protecting the car's air conditioning system, and preventing glass fogging.

[0003] Air conditioning filter paper effectively blocks dust and fine particulate matter in the air. Bending the filter paper significantly increases its surface area, allowing more liquid or air to pass through and be filtered out, thus improving filtration efficiency. During the bending process, to support the unwound filter paper and prevent it from becoming loose during transport, which could lead to wrinkles and compromise its structural integrity, an anti-loosening structure for automotive air conditioning filter paper bending has been designed. This structure adds a driven roller between the bending device and the unwound roller, and lifts the driven roller, providing upward support to the filter paper passing over its surface. This prevents the filter paper from becoming loose during transport, thus avoiding wrinkles during bending and compromising its structural integrity. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-loosening structure for bending filter paper in automotive air conditioning filters, which prevents the filter paper from becoming loose during the conveying process, thus avoiding wrinkles during bending and compromising the structural integrity of the filter paper after bending, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A structure for preventing loosening of filter paper for bending in an automotive air conditioning filter, comprising a support plate: support grooves are fixedly connected to the left and right sides of the top of the support plate by bolts; support rods are slidably connected to the inner cavities of the two support grooves; racks are fixedly connected to the rear side of the support rods; limit rods are fixedly connected to the inner cavities of the two support grooves; L-shaped rods are rotatably connected to the surface of the limit rods; a locking tooth is welded to the top of the L-shaped rod; the surface of the locking tooth meshes with the surface of the rack; arc-shaped sliding grooves are opened on the inner walls of the two support grooves; rotating wheels are slidably connected to the inner cavities of the two arc-shaped sliding grooves; and toothed heads are fixedly connected to the side of the two rotating wheels near the support rods.

A toothed head 8 is fixedly connected to each side of the support plate 1. A connecting rod 9 is fixedly connected to the side of the two rotating wheels 7 opposite to the toothed head 8. A round rod 10 is fixedly connected between the two connecting rods 9. Limiting strips are fixedly connected to the left and right sides of the inner cavity of the support groove 2. Limiting grooves 11 are opened on the left and right sides of the support rod 3. The surface of the limiting strip is slidably connected to the surface of the limiting groove 11. Through the setting of the limiting groove 11, the support rod 3 can obtain a vertically upward guiding force during the upward sliding process, so that the support rod 3 can be limited during sliding and avoid shaking. A bending device 17 is provided on the front side of the support plate 1, and an unwinding roller 18 is provided on the rear side of the support plate 1. Example 2

[0024] Figure 1-4This invention illustrates an embodiment of an anti-loosening structure for bending filter paper in an automotive air conditioning filter, comprising: a support plate 1; support grooves 2 are bolted to the left and right sides of the top of the support plate 1; support rods 3 are slidably connected to the inner cavities of the two support grooves 2; racks are fixedly connected to the rear sides of the support rods 3; limit rods 4 are fixedly connected to the inner cavities of the two support grooves 2; L-shaped rods 5 are rotatably connected to the surface of the limit rods 4; locking teeth 6 are welded to the top of the L-shaped rods 5; the surface of the locking teeth 6 meshes with the surface of the rack; arc-shaped grooves are formed on the inner walls of the two support grooves; rotating wheels 7 are slidably connected to the inner cavities of the two arc-shaped grooves. Each rotating wheel 7 has a toothed head 8 fixedly connected to one side near the support rod 3. A spring plate 12 is fixedly connected to the bottom of the inner cavity of the support groove 2. The spring plate 12 can provide auxiliary support for the support rod 3 in the placed state, and can make it easier to deflect the L-shaped rod 5 by stepping on it. The support rod 3 is placed on the top of the spring plate 12. Springs 13 are welded between the rear side of the two L-shaped rods 5 and the top of the support plate 1. The top of the two springs 13 is fixedly connected to a pressure plate 14. A driven roller 15 is rotatably connected between the two support rods 3. Limiting wheels 16 are fixedly connected to the left and right sides of the surface of the driven roller 15.

[0025] Working principle: When using this utility model, the user steps on the pressing plate 14 to deflect the L-shaped rod 5, which in turn causes the locking teeth 6 to disengage from the surface of the rack, thus releasing the restriction on the support rod 3. Next, the user pushes the round rod 10 forward and downward to drive the rotating wheel 7 to slide. At this time, under the action of the arc-shaped groove, the rotating wheel 7 slides forward and downward, and the surface of the tooth head 8 engages with the rack. Then, the user pulls the round rod 10 downward to deflect the rotating wheel 7, and through the tooth head 8 and the rack, drives the support rod 3 to slide upward, thereby causing the driven roller 15 to advance... The filter paper slides upwards, releasing the pressure plate 14. Under the rebound force of the spring 13, the L-shaped rod 5 and the locking teeth 6 are reset, thus fixing the position of the support rod 3 after sliding. Then, the bending device 17 is activated to pull the filter paper on the surface of the unwinding roller 18 and bend the filter paper. The filter paper then passes over the surface of the driven roller 15 and receives an upward support force through the driven roller 15. This avoids the filter paper from becoming loose during the conveying process, which would cause wrinkles during bending and damage the structural integrity of the filter paper after bending.

[0026] In summary, the anti-loosening structure for bending filter paper in this automotive air conditioning filter works by pushing the round rod 10 to slide the rotating wheel 7 forward and downward under the action of the arc-shaped sliding groove, and making the surface of the tooth 8 mesh with the rack. Then, the round rod 10 is pulled down to drive the support rod 3 to slide upward, which in turn causes the driven roller 15 to drive the filter paper to slide upward. This achieves the purpose of preventing the filter paper from becoming loose during the conveying process, which would cause wrinkles to form during bending and thus damage the structural integrity of the filter paper after bending.
