Description

Technical Field

[0001] The invention relates to the technical field of filter bag processing equipment, and in particular to a non-woven fabric production equipment for vacuum cleaner filter bags. Background Art

[0002] There are many kinds of materials for making filter bags, commonly used are silk, fiber cloth, non-woven fabrics, etc. Various materials have different physical and chemical properties. Among them, filter bags made of nanofiber materials, graphene materials, etc. have stronger filtering and adsorption capabilities; vacuum cleaners generally use filter bags made of non-woven fabrics;

[0003] Non-woven filter bags are usually made of non-woven materials such as polyester, polypropylene or nylon, which have better strength, durability and filtration efficiency; non-woven filter bags usually use hot pressing or needle punching process to bond different non-woven materials, which improves the performance of non-woven materials and makes the non-woven materials more compact, thereby improving the filtration efficiency and filtration area of ​​non-woven filter bags;

[0004] The non-woven fabric material is generally wound on a winding roller, and the two sides of the non-woven fabric material are curled unevenly. Therefore, after the non-woven fabric materials are bonded, the two sides are still curled unevenly, so the curled uneven parts on both sides of the bonded non-woven fabric are cut off, leaving the flat part of the non-woven fabric. The cut part cannot be used, causing waste, thus causing limitations.

[0005] To this end, we propose a non-woven fabric production equipment for vacuum cleaner filter bags. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a non-woven fabric production device for vacuum cleaner filter bags, which overcomes the deficiencies in the prior art and aims to solve the problems in the background technology.

[0009] The frame is provided with a flattening mechanism, which is used to pull the side of the non-woven material when the laminating mechanism is bonding the non-woven material, so that the side of the non-woven material is as flat as possible, reducing the part cut by the cutting tool.

[0010] Preferably, the leveling mechanism includes a mounting frame, a rotating shaft, a rotating belt and a hooking plate; two pairs of the mounting frames are respectively arranged on both sides of the pressing mechanism, and the two pairs of the mounting frames are located on both sides of the non-woven fabric, and the mounting frames are fixedly connected to the machine; a pair of the rotating shafts are rotatably connected to the mounting frames; a driving motor is fixedly connected inside the mounting frame; the output end of the driving motor is fixedly connected to the rotating shaft; the rotating belt is sleeved on the outside of a pair of rotating blocks; the hooking plate is evenly mounted on the rotating belt, the hooking plate can rotate, the hooking plate is evenly fixed with hook needles, and a magnet block is installed on the hooking plate; the mounting frame is evenly fixed with electromagnets.

[0011] The hooks on the hooking plates hook the two sides of the non-woven material, so that the hooking plates on both sides of the pressing mechanism straighten the side edges of the non-woven material through the speed difference between the rotating shafts, and then the pressing mechanism presses the various non-woven materials into one piece, so that the two sides of the non-woven material are straightened from the original curled state, and are pressed by the pressing mechanism in the straightened state, thereby minimizing the curled parts on both sides of the non-woven material and reducing waste.

[0012] Preferably, a rotating seat is evenly fixed on the rotating belt; a rotating block is rotatably connected to the rotating seat via a torsion spring; the rotating block is rotatably connected to the hook plate; a tilting block is fixed on the rotating seat; a guide rod is fixed on the hook plate; and the guide rod is in contact with the tilting block.

[0013] Preferably, the tilting directions of the tilting blocks on both sides of the pressing mechanism are opposite.

[0014] The non-woven fabric material is stretched obliquely on both sides by the hook hook on the hooking plate, so that the non-woven fabric material is stretched in the horizontal and vertical directions at the same time, thereby eliminating the wrinkles in the middle part of the non-woven fabric material in the horizontal and vertical directions, and preventing multiple non-woven fabric materials from overlapping and wrinkling. After being pressed by the pressing mechanism, the non-woven fabric is wrinkled, thereby improving the quality of the non-woven fabric produced by the present invention.

[0015] Preferably, a sliding frame is fixedly connected to the hook plate; the magnet block is slidably connected in the sliding frame; an ejection plate is provided under the hook plate; a toggle rod is hinged on the ejection plate; the other end of the toggle rod is rotatably connected to the magnet block; the toggle rod and the sliding frame are hinged; a hole is opened on the ejection plate; the hook needle can be inserted into the hole on the ejection plate.

[0018] Preferably, the clamping block is L-shaped.

[0019] The hooking plate hooks the two ends of the non-woven material and pulls the non-woven material to both sides, which will cause the non-woven material on both sides to have more non-woven material on the outside of the hooking plate and cause curling. At this time, the controller controls the clamping motor to rotate, so that the two clamping blocks move towards each other, clamping the non-woven material on the outside of the hooking plate, so that the curling of the non-woven material at this point will not be transmitted to the rear. At the same time, the controller controls the blocking motor to drive the blocking shaft to rotate, so that the clamping block moves with the non-woven material, and then the clamping block releases the non-woven material, and the subsequent clamping blocks clamp the non-woven material again.

[0020] Beneficial effects of the present invention:

[0021] 1. The present invention hooks the two sides of the non-woven fabric material by the hook needles on the hooking plate, so that the hooking plates on both sides of the pressing mechanism straighten the side edges of the non-woven fabric material through the speed difference between the rotating shafts, and then the pressing mechanism presses the various non-woven fabric materials into one piece, so that the two sides of the non-woven fabric material are straightened from the original curled state, and pressed by the pressing mechanism in the straightened state, thereby minimizing the curled parts on both sides of the non-woven fabric material and reducing waste.

[0022] 2. The present invention stretches the non-woven fabric material obliquely on both sides by hooking the hooks on the plate, so that the non-woven fabric material is stretched in the horizontal and vertical directions at the same time, thereby eliminating the wrinkles in the middle part of the non-woven fabric material in the horizontal and vertical directions, and preventing multiple non-woven fabric materials from overlapping and wrinkling. After being pressed by the pressing mechanism, the non-woven fabric is wrinkled, thereby improving the quality of the non-woven fabric produced by the present invention.

[0037] When the laminating mechanism 2 is laminating different types of non-woven fabrics, the controller controls the driving motors 45 in the mounting frames 41 on both sides of the laminating mechanism 2 to rotate with the corresponding rotating shafts 42, so that the rotating shafts 42 rotate with the rotating belts 43, and then the controller controls the electromagnets 48 to pass current, so that the electromagnets 48 generate magnetic force to attract the magnet block 47 to move downward, so that the magnet block 47 rotates downward with the hook plate 44, so that the hook needle 46 on the hook plate 44 is inserted into the non-woven fabric material, so that the hook plate 44 is fixed to the non-woven fabric material, and when the hook plate 44 rotates to the front end of the rotating belt 43, the controller controls the electromagnet 48 to pass reverse current. , so that the electromagnet 48 pushes the magnet block 47 to move upward, driving the hook plate 44 to rotate upward, so that the hook needle 46 is separated from the non-woven material, and the hook plate 44 on the rotating belt 43 hooks the non-woven material and then separates, and the reciprocating cycle is repeated; the rotating shafts 42 on the mounting frames 41 on both sides of the pressing mechanism 2 rotate at a differential speed, so that the hook plates 44 in the two mounting frames 41 rotate at different speeds as the rotating belt 43 rotates, so that the two sides of the non-woven material between the mounting frames 41 on both sides of the pressing mechanism 2 are straightened, so that when the pressing mechanism 2 is pressing, the curled parts on both sides of the non-woven material are straightened, thereby reducing the curled parts after pressing, and further reducing the parts that need to be cut;

[0040] In this embodiment, the tilting blocks 53 on both sides of the pressing mechanism 2 are tilted in opposite directions.

[0041] In the present invention, when the hook plate 44 rotates downward, the guide rod 54 on the hook plate 44 slides along the inclined block 53, causing the hook plate 44 to deflect, and the inclined blocks 53 on both sides of the pressing mechanism 2 are inclined in opposite directions. The hook plates 44 on the mounting frames 41 on both sides of the pressing mechanism 2 deflect toward both sides, so that the non-woven fabric material is stretched toward the side by the hook needles 46, which can be decomposed into stretching the non-woven fabric material in the horizontal and vertical directions, that is, reducing the curling of the non-woven fabric material on both sides in the vertical direction, and at the same time, the non-woven fabric material is stretched before being pressed by the pressing mechanism 2, eliminating the wrinkles in the middle part of the non-woven fabric material, thereby improving the effect of flattening the two sides of the non-woven fabric material of the present invention; after the hook plate 44 rotates upward, the guide rod 54 and the inclined block 53 are out of contact, so that the torsion spring 51 between the rotating seat 5 and the rotating block 52 causes the rotating block 52 to rotate with the hook plate 44 and return to its original position;

[0042] The present invention stretches the non-woven material obliquely on both sides by means of the hook needle 46 on the hooking plate 44, so that the non-woven material is stretched in the horizontal and vertical directions at the same time, thereby eliminating the wrinkles in the middle part of the non-woven material in the horizontal and vertical directions, and preventing multiple non-woven materials from overlapping and wrinkling.

At this time, the controller controls the clamping motor 75 to rotate, so that the two clamping blocks 74 move toward each other, clamping the non-woven material outside the hook plate 44, so that the curling of the non-woven material at this point will not be transmitted to the rear. At the same time, the controller controls the blocking motor 71 to drive the blocking shaft 7 to rotate. The clamping block 74 moves with the non-woven material, and then the clamping block 74 releases the non-woven material, and the subsequent clamping block 74 clamps the non-woven material again; in the present invention, the clamping block 74 is arranged to be L-shaped, so in the process of the clamping block 74 clamping the non-woven material, the non-woven material is clamped into an L-shape by the clamping block 74, so that the excess part of the non-woven material is pulled by the clamping block 74, further eliminating the influence of the extra non-woven material on the outer part caused by the hook plate 44 pulling the non-woven material.
