[0039] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Example

[0041] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0042] An air filter paper rolling device, comprising:

[0043] Bottom plate 1;

[0044] A vertical plate 27, fixed to one side of the top of the bottom plate 1;

[0045] The reel 2 has one end rotatably connected to one side end of the vertical plate 27;

[0046] The winding roller 3 is fixed on the circumferential surface of the winding shaft 2;

[0047] An adjusting groove 4 is provided on the circumferential surface of the winding roller 3;

[0048] The screw rod 5 is rotatably connected between the inner walls of the adjusting groove 4, and one end of the screw rod 5 movably penetrates to one side end of the winding roller 3 and extends outward;

[0049] A locking mechanism connected to the screw rod 5 to fix it;

[0050] A nut block 6 is threadedly connected to the circumferential surface of the screw rod 5;

[0051] A connecting block 7 is fixed to the top of the nut block 6;

[0052] The positioning slide plate 8 is sleeved on the circumferential surface of the winding roller 3 and fixed to the connecting block 7 .

[0053] The filter paper of the present invention is wound on the filter paper 2 and the filter paper 3 is wound on the filter paper 2. The filter paper 2 is wound on the filter paper 2 and the filter paper 3 is wound on the filter paper 2. The filter paper 2 is wound on the filter paper 2 and the filter paper 3 is wound on the filter paper 2.

[0054] Specifically, the locking mechanism includes:

[0055] A first gear 9 is fixed to the surface of the extended end of the screw rod 5;

[0056] A fixed rod 11 is fixed to one side end of the winding roller 3;

[0057] The limiting groove 12 is formed on the circumferential surface of the fixing rod 11;

[0058] The limiting block 14 is slidably connected in the limiting groove 12;

[0059] The second gear 10, whose inner wall is fixed to the stopper 14 and slidably connected to the surface of the fixing rod 11, is meshed with the first gear 9;

[0060] The spring 13 has one end fixed to the second gear 10 and the other end fixed to the end of the winding roller 3 . The spring 13 is sleeved on the surface of the fixing rod 11 .

[0061] In this embodiment: the screw rod 5 can be fixed by the locking mechanism, so that the positioning slide plate 8 is fixed after adjusting its position and is not easy to move. In the locking mechanism, the second gear 10 can slide linearly on the surface of the fixed rod 11 through the limit block 14. Since the limit block 14 is embedded in the limit groove 12, the position of the second gear 10 is limited and cannot rotate. At this time, when the second gear 10 is engaged with the first gear 9, the first gear 9 is fixed, so that the first gear 9 cannot rotate, thereby causing the screw rod 5 to be unable to rotate. When the second gear 10 slides inward, the second gear 10 will squeeze the spring 13 and disengage from the first gear 9, so that the first gear 9 can rotate. After releasing the second gear 10, the elasticity of the spring 13 can make the second gear 10 reset and engage with the first gear 9, thereby locking the first gear 9.

[0062] Specifically, one side end of the vertical plate 27 is also rotatably connected to the two transmission shafts 15 , and the ends of the two transmission shafts 15 are movable through the back side of the vertical plate 27 and extend, and transmission rollers 16 are fixed to the circumferential surfaces of the two transmission shafts 15 .

[0063] In this embodiment: the transmission shaft 15 is used to drive the transmission roller 16 to rotate. The gap between the two transmission rollers 16 is small and is used to accommodate the conductive filter paper, so that when the filter paper is rolled up on the surface of the winding roller 3, it is conducted between the two transmission rollers 16.

[0064] Specifically, a motor 22 is provided on the back of the vertical plate 27, and the output end of the motor 22 movably passes through the vertical plate 27 and is fixed to the end of the winding shaft 2, and an I-shaped wheel 24 is fixed to the output end of the motor 22 and the extended end of one of the transmission shafts 15, and a belt 25 is connected for transmission between the circumferential surfaces of the two I-shaped wheels 24, and a third gear 23 is fixed to the extended end surfaces of the two transmission shafts 15, and the two third gears 23 are meshed with each other.

[0065] In this embodiment: a support seat 26 is also fixed to the back of the vertical plate 27, and a motor 22 is fixed to the top of the support seat 26. The output end of the motor 22 can drive the winding shaft 2 to rotate to wind up the filter paper. At the same time, power is transmitted through the I-shaped wheel 24 and the belt 25 so that one of the transmission shafts 15 can rotate, and the transmission shaft 15 can drive the third gear 23 on its surface to rotate. Since the two third gears 23 are meshed, the other third gear 23 drives the other transmission shaft 15 to rotate, and finally the two transmission rollers 16 rotate at the same time, and the rotation directions are opposite, so that the filter paper can be transmitted to the side close to the winding roller 3.

[0066] Specifically, two rectangular hollow seats 17 are fixed on the top of the base plate 1, and sliders 18 are movably inserted in the two rectangular hollow seats 17. A concave frame 19 is fixed on the top of the slider 18. Guide rollers 20 are rotatably connected between the inner walls on both sides of the concave frame 19. A cylinder 21 is fixed to the bottom of the concave frame 19, and the base of the cylinder 21 is fixed to the top of the base plate 1.

[0067] In the present embodiment, the guide roller 20 is provided, and the guide roller 20 can rotate in the concave frame 19, so that when the filter paper is rolled up onto the winding roller 3 via the surface of the transmission roller 16, it passes through one side of the surface of the guide roller 20 in the middle for conduction. Since the guide roller 20 can be adjusted in height by the cylinder 21, when the filter paper is rolled up, the filter paper passes through the surface of the guide roller 20. After being conducted by the guide roller 20, the filter paper is straightened and can be better rolled up by the winding roller 3. When the guide roller 20 moves, it drives the slider 18 to slide in the rectangular hollow seat 17, which can further support the concave frame 19, so that the concave frame 19 is not easy to tilt.

[0068] It should be noted that the cylinder 21 and the motor 22 are both existing technologies, and corresponding models can be selected according to actual needs, which will not be described in detail.

[0069] The working principle and use process of the utility model are as follows: when the device is used, the filter paper passes between the two transmission rollers 16, and then is rolled onto the surface of the winding roller 3 through the surface of the guide roller 20, and then the position of the positioning slide plate 8 is adjusted according to the width of the filter paper, and the nut block 6 is driven to move by rotating the screw rod 5, and the positioning slide plate 8 is driven by the connecting block 7 to slide on the surface of the winding roller 3, so that one side surface of the positioning slide plate 8 is always in contact with the filter paper, so that the filter paper is not easily shifted when winding, and then the screw rod 5 is fixed by the locking mechanism, and the motor 22 is started at the same time, so that the winding roller 3 is rotated for winding.

[0070] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
