Description

Technical Field

[0001] The utility model relates to the field of non-woven fabric production, in particular to a non-woven fabric folding mechanism. Background Art

[0002] Woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is called cloth because of its appearance and certain properties. As an excellent filter material, non-woven fabric is often used to make automobile air conditioning filter elements. In order to increase the filter area and improve the filter effect, the non-woven fabric is generally folded and divided and packaged.

[0003] However, when folding, the existing non-woven fabric folding mechanism needs to pass the non-woven fabrics through the folding plates one by one and then be conveyed by the conveying roller to the cutting device for cutting, and finally packaged. When the non-woven fabric is initially loaded, one end of the non-woven fabric needs to pass through the gap between the two bottom folding plates and then pass through the gaps of multiple folding plates in sequence. At this time, the spacing between the two symmetrically distributed folding plates needs to be adjusted to increase the gap to facilitate the passage of the non-woven fabric. In order to achieve efficient operation of this step, a non-woven fabric folding mechanism is provided. Summary of the invention

[0004] The utility model aims to provide a non-woven fabric folding mechanism in order to further improve the feeding efficiency of the non-woven fabric at the folding plate position.

[0007] The three screws are slidably connected to the first gear on one side close to the discharge roller, and the support frame is equidistantly fixedly connected to the first gear on one side, the two connecting rods are respectively distributed in the middle of two adjacent screws, and the outer sides of the two connecting rods are rotatably connected to the second gear;

[0008] An annular protrusion is formed on one side of the three screw rods close to the first gear, and a plurality of annularly distributed springs are arranged between the annular protrusion and the first gear.

[0009] As a further solution of the utility model: the three screws are formed with external threads on the outer side of one end close to the folding convex plate, and the folding convex plate, the folding concave plate and the support frame are provided with through holes for the limit rod and the screw to pass through.

At the same time, the rotation of the screw drives the other first gear and the second gear to cooperate to drive the other two screws to rotate, thereby driving the other two folding convex plates to move and open, so that the material can be loaded. Afterwards, in order to avoid damage to the non-woven fabric, the first gear can be pressed to rotate the screw in sequence to drive the folding convex plate to move and cooperate with the folding concave plate.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions 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.

[0021] See also Figure 1 to Figure 4 In the embodiment of the utility model, a non-woven fabric folding mechanism includes a cutting and conveying device 1, a plurality of conveying rollers 2 are rotatably installed on one side of the cutting and conveying device 1, a folding and shaping mechanism 4 is arranged below one side of the cutting and conveying device 1, and a feeding roller 3 providing feeding support for the non-woven fabric is arranged on one side of the folding and shaping mechanism 4;

[0022] The folding and shaping mechanism 4 comprises a support frame 401, two support frames 401 are symmetrically arranged, three folding concave plates 402, folding convex plates 403, limiting rods 404, and screws 409 are equidistantly arranged between the two support frames 401, the limiting rods 404 and the screws 409 are symmetrically arranged, one end of the limiting rods 404 and the screws 409 respectively penetrates the two sides of the two support frames 401, the folding convex plates 403 are distributed on one side of the support frame 401 and are sleeved on the outer sides of the limiting rods 404 and the screws 409, and the folding concave plates 402 are fixed between the two support frames 401 and are aligned with the folding convex plates 403;

[0023] The three screw rods 409 are slidably connected to the first gear 405 on one side close to the unloading roller 3, and the support frame 401 is equidistantly fixedly connected to the first gear 405 on one side. The two connecting rods 408 are respectively distributed in the middle of two adjacent screw rods 409, and the outer sides of the two connecting rods 408 are rotatably connected to the second gear 406;

[0024] An annular protrusion is formed on one side of the three screw rods 409 close to the first gear 405 , and a plurality of annularly distributed springs 407 are arranged between the annular protrusion and the first gear 405 .

[0025] In this embodiment: when in use, the rolled non-woven fabric is sleeved on the outside of the unwinding roller 3, and then the non-woven fabric is sequentially passed through the folding concave plate 402 from bottom to top, and then passed through multiple conveying rollers 2 to enter the working interface of the cutting and conveying device 1, and then the first gear 405 is pressed sequentially from bottom to top to release the engagement with the second gear 406, and then the screw 409 is rotated to drive the folding convex plate 403 to move and engage with the folding concave plate 402, and then the cutting and conveying device 1 is started to cut, and finally packaged;

[0026] When the rolled non-woven fabric is used up and needs to be replaced, it is only necessary to rotate any one of the screws 409. The rotation of the screw 409 drives the corresponding first gear 405 to rotate and cooperate with the second gear 406, thereby driving the other two first gears 405 to rotate synchronously. The rotation of the other two first gears 405 drives the corresponding screw 409 to rotate so that the folding convex plate 403 moves and disengages from the folding concave plate 402. After that, it is only necessary to repeat the previous operating steps to continue folding, splitting and packaging. In this way, the replacement can be opened synchronously and the operation can be locked in sequence, and the operation is simpler.

[0027] Please refer to Figure 2 to Figure 4 The three screws 409 are formed with external threads on the outer side of one end close to the folding convex plate 403, and the folding convex plate 403, the folding concave plate 402, and the support frame 401 are provided with through holes for the limit rod 404 and the screws 409 to pass through. The through holes provided in the folding convex plate 403 are formed with internal threads threadedly connected to the screws 409, and the three screws 409 and the support frame 401 are arranged in a rotating connection structure.

[0028] In this embodiment: through this structural setting, a screw structure is formed, so that when the screw 409 is rotated, the folding convex plate 403 can be driven to move, so that the folding convex plate 403 and the folding concave plate 402 are locked together to ensure the normal operation of the mechanism.

[0029] Please refer to Figure 1 to Figure 4 The three folding concave plates 402 and the folding convex plates 403 are close to each other on one side and are provided with folding grooves with decreasing folding angles from bottom to top. The three folding convex plates 403 and the folding concave plates 402 are close to each other on one side and are formed with protrusions matching the folding grooves.

[0030] In this embodiment: through this structural setting, the non-woven fabric is folded and formed through the cooperation of three folding concave plates 402 and folding convex plates 403 to achieve the desired effect.

[0031] Please refer to Figure 2 to Figure 4 The first gear 405 is synchronously meshed with two second gears 406 distributed at its upper and lower ends to achieve synchronous transmission.

[0032] In the present embodiment: through this structural setting, when the subsequent roll of non-woven fabric is used up and needs to be replaced, it is only necessary to rotate any one of the screws 409. The rotation of the screw 409 drives the corresponding first gear 405 to rotate and cooperate with the second gear 406, thereby driving the other two first gears 405 to rotate synchronously. The rotation of the other two first gears 405 drives the corresponding screw 409 to rotate so that the folding convex plate 403 moves and is released from the folding concave plate 402, thereby achieving the effect of synchronous release of cooperation, which is convenient for loading.

[0033] Please refer to Figure 1 to Figure 4 A cross protrusion is formed at one end of the three screw rods 409 close to the first gear 405, and a cross groove matching the cross protrusion is opened inside the first gear 405.

[0034] In this embodiment: through this structural setting, the first gear 405 and the screw rod 409 form a sliding connection, and it is ensured that the rotation of the first gear 405 can drive the screw rod 409 to rotate, so as to facilitate the subsequent movement of the three folding convex plates 403 in sequence. The specific operation steps are: the first gear 405 is pressed outward to release the cooperation with the second gear 406. During this process, the spring 407 is compressed. After the cooperation is released, the first gear 405 is rotated to drive the screw rod 409 to rotate. The rotation of the screw 409 drives the folding convex plate 403 to move to cooperate with the folding concave plate 402. Then, the pressing on the first gear 405 is released. Under the restoring force of the spring 407, the first gear 405 is reset and re-matched with the second gear 406. In this way, the other two first gears 405 repeat the operation to realize the movement and cooperation of the three folding convex plates 403 in sequence.

[0035] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
