[0001] The invention belongs to the technical field of filter element production, and in particular relates to a double-side strip auxiliary support tooling for an air-conditioning filter element. Background Art

[0002] Air conditioning filter, also known as air conditioning filter, is used to filter impurities contained in indoor air or air entering the room from the outside, so as to improve the cleanliness of the air, prevent such substances from entering the air conditioner and damaging the air conditioning system, and ensure the indoor air quality.

[0003] Attaching strips on both sides of the filter element can support the filter element body, making it more stable during use. The filter element is in a compressed state before the strips are attached. In the existing technology, workers need to manually stretch it to fully expand it. After loosening the two ends of the filter element, the filter element will shrink back to the working state under its own elasticity. The workers manually stretch the filter element, which is inefficient and affects the speed of strip attachment. Summary of the Invention

Both sides of the stabilizing frame are provided with a wedging mechanism. The air conditioning filter element is placed on the top of the placement base. The top of the placement base is provided with a stretching assembly. The stretching assembly includes a fixed strip, a movable strip and a pushing device. The fixed strip is fixedly connected to the placement base, and the pushing device drives the movable strip to reciprocate in the length direction of the placement base.

[0006] The pushing device includes a ball screw and a lifting rack, a slider is sleeved on the surface of the ball screw, one end of the ball screw is fixedly connected to an auxiliary block, a rotating gear is sleeved on the surface of the auxiliary block, the rotating gear is meshed with a surface of a section of the lifting rack, a first spring is fixedly connected between one end of the slider and the placement base, and a second spring is fixedly connected between the lifting rack and the placement base;

[0007] During the descent of the stabilizing frame, the movable bar is moved by the pushing device, and the air-conditioning filter element between the fixed bar and the movable bar is automatically pulled and unfolded.

[0008] As a preferred embodiment of the above technical solution, the stretching assembly further includes a blocking block, one end of which is fixedly connected to a pull rod, and a third spring is sleeved on the surface of the pull rod.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Figure 1-Figure 4 In the figure, the air conditioning filter element double-sided sticker auxiliary support tooling includes a placement base 11 and a stabilizing frame 12. Both sides of the stabilizing frame 12 are provided with a wedging mechanism. The air conditioning filter element is placed on the top of the placement base 11. The top of the placement base 11 is provided with a stretching component. The stretching component includes a fixed bar 13, a movable bar 14 and a pushing device. The fixed bar 13 is fixedly connected to the placement base 11. The pushing device drives the movable bar 14 to reciprocate in the length direction of the placement base 11. The tops of the fixed bar 13 and the movable bar 14 are both concave and convex slot-shaped. The air conditioning filter element is inserted into the concave and convex slot on the top of the fixed bar 13 or the movable bar 14;

[0023] The pushing device includes a ball screw 21 and a lifting rack 22. A slider 23 is sleeved on the surface of the ball screw 21. One end of the ball screw 21 is fixedly connected to an auxiliary block 24. A rotating gear 25 is sleeved on the surface of the auxiliary block 24. The rotating gear 25 is engaged with a surface of the lifting rack 22. A first spring 26 is fixedly connected between one end of the slider 23 and the placement base 11. A second spring 27 is fixedly connected between the lifting rack 22 and the placement base 11.

[0024] During the descent of the stabilizing frame 12 , the movable bar 14 is moved by the pushing device, and the air-conditioning filter element between the fixed bar 13 and the movable bar 14 is automatically pulled and unfolded.

[0025] When it is necessary to perform bilateral stripping on the air conditioning filter element, the filter element is placed on the top of the placement base 11, and the fixed bar 13 and the movable bar 14 fix the two ends of the filter element. Because the tops of the fixed bar 13 and the movable bar 14 are both concave-convex slot-shaped, the two ends of the filter element can be quickly inserted into their concave-convex slots, and the concave-convex slots of the fixed bar 13 or the movable bar 14 frictionally fix the surface of the filter element, and then the external power mechanism drives the stabilizing frame 12 to move down and contact the top of the filter element. During the downward movement of the stabilizing frame 12, the bottom of the stabilizing frame 12 contacts the top of the lifting rack 22 and pushes it down, and the second spring 27 is compressed and deformed accordingly. The movement of the lifting rack 22 causes the rotating gear 25 to rotate, and the auxiliary block 24 drives the ball screw 21 to rotate. The slider 23 drives the movable bar 14 to move, causing the first spring 26 to stretch, and the movement of the movable bar 14 stretches one end of the air conditioning filter element to fully unfold it.

[0026] The downward movement of the stabilizing frame 12 is used to provide power for the pushing device, and the moving bar 14 can pull one end of the filter element to fully unfold it without manual operation by workers.

[0027] Figure 2 In the embodiment, the stretching assembly further comprises a blocking block 31 , one end of which is provided with a slope, one end of which is fixedly connected to a pull rod 32 , and a third spring 33 is sleeved on the surface of the pull rod 32 .

[0028] When the rotating gear 25 rotates with the movement of the lifting rack 22, the slider 23 drives the moving bar 14 to move past the position of the blocking block 31. The slider 23 is squeezed and contracted by the slope position of the blocking block 31, and the third spring 33 is squeezed and deformed accordingly. After the slider 23 leaves the position of the blocking block 31, the third spring 33 resets and pushes the blocking block 31 to reset. When the rotating gear 25 disengages from the tooth position of the lifting rack 22, the second spring 27 in the stretched state pulls the slider 23 back until its end contacts the blocking block 31, and the ball screw 21 rotates accordingly and drives the auxiliary block 24 and the rotating gear 25 to rotate. Because the blocking block 31 blocks the slider 23, the moving bar 14 will not move to the initial position. At this time, the distance between the moving bar 14 and the fixed block is the stretched state when the filter element is working.

[0029] The blocking block 31 is used to block the reset path of the moving bar 14, preventing the moving bar 14 from being fully reset so that the filter element returns to the folded state, and the filter element is in a stretched state during operation to work against the edge, thereby being able to fully stretch the filter element and shrink it back to the required stretched state.

[0030] Figure 3 In the figure, a plurality of limit blocks 41 are rotatably inserted on the surface of the auxiliary block 24 , a torsion spring is provided between the limit blocks 41 and the auxiliary block 24 , and a plurality of limit grooves 42 matching the limit blocks 41 are provided on the inner surface of the rotating gear 25 .

[0031] After the wedging work is completed, the external power mechanism retracts the stabilizing frame 12, and the second spring 27 in the compressed state pushes the lifting rack 22 to reset, and the rotating gear 25 rotates accordingly, and the limiting groove 42 contracts the limiting block 41, and the auxiliary block 24 and the ball screw 21 do not rotate.

[0032] By cooperating with the limiting block 41 and the limiting groove 42, the pushing device can be changed to a one-way push on the moving bar 14, avoiding the pushing device pushing the moving bar 14 in the reverse direction so that the filter element is squeezed by external force and the strips on both sides are damaged.

[0033] Figure 1 and Figure 4 In the figure, the wedging mechanism includes a moving frame 51 and a flip plate 52, a clamping plate 53 is provided on the top of the flip plate 52, and cylinders 54 are provided on both sides of the bottom of the flip plate 52, and the bottom of the clamping plate 53 is fixedly connected to the output end of the cylinder 54.

[0034] Rotating parts are provided on both sides of the flip plate 52 . The rotating parts of the flip plate 52 are rotatably inserted into the movable frame 51 , and one end of the rotating part is fixedly connected to a rotating shaft 55 .

[0035] After the stabilizing frame 12 is fitted with the top surface of the filter element, the external feeding mechanism feeds the cut strips between the flip plate 52 and the clamping plate 53, and the cylinder 54 at the bottom of the clamping plate 53 drives the clamping plate 53 to move, and the clamping plate 53 clamps and fixes the strips. Then the external power mechanism drives the flip plate 52 to rotate 90 degrees through the rotating shaft 55, and then the two edge-adhesive mechanisms move toward each other to apply strips to both sides of the filter element. After the stripping is completed, the cylinder 54 retracts the clamping plate 53, and the edge-adhesive mechanism can be reset to wait for the next stripping work.

[0036] The wedging mechanism can perform stripping on both sides of the filter element and ensure the stability of the stripping to prevent the stripping from separating from the wedging mechanism.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
