Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, specifically to a high-efficiency double-sided depilatory machine. Background Technology

[0002] Fabric surfaces have fine fibers, short fibers, and loose hairs of varying lengths, as well as stray hairs along the fabric edges. During the hair removal process, wrinkles can easily create blind spots for hair removal. Furthermore, when removing hair from long-fiber, fluffy fabric surfaces, fiber entanglement can occur, leading to frequent machine shutdowns for cleaning.

[0003] Some fabrics require lint removal on both sides. However, the lint removal process typically involves removing lint from the front side first, followed by the back side. This process is time-consuming, labor-intensive, and costly. Furthermore, removing lint from the back side can cause the front side, which has already been linted, to fuzz again, significantly impacting the lint removal effect and resulting in incomplete lint removal. Additionally, the lint cannot be removed promptly after lint removal, causing secondary pollution.

[0004] Different models of lint removal machines are required for fabrics of different thicknesses. Lint removal machines are not universal, have low efficiency and high error rate. In addition, the traditional simple fan has uneven air pressure, causing the fabric to be sometimes tight and sometimes loose, which damages the original texture of the fabric and does not remove lint completely.

[0005] During the fabric weaving process, it is inevitable that needles or metal residues will remain. Before or after the removal of fibers, manual or specialized equipment is required to rescan the fabric, which results in high rework costs, omissions, and affects subsequent processing and sales. Summary of the Invention

[0006] The purpose of this invention is to provide a high-efficiency double-sided lint removal machine to solve the problems mentioned in the background art. This invention creates a lint removal gap between a first lint removal component and a liftable second lint removal component, allowing the fabric to pass through. The size of this gap can be adjusted according to the fabric thickness. This enables simultaneous lint removal on both sides of fabrics of various thicknesses. The fabric passes through the upper and lower lint removal surfaces at a uniform speed, simultaneously removing lint. Negative pressure adsorption removes fine lint, short lint, loose fibers, and lint from the fabric surface and edges. This method offers advantages such as thorough lint removal, short lint removal cycle, no need for manual flipping for reverse lint removal, efficient one-time lint removal, and no secondary pollution.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency double-sided lint removal machine, comprising a frame, one side of which is a fabric inlet side and the other side is a fabric outlet side. A double-sided lint removal assembly is provided between the fabric inlet side and the fabric outlet side.

An upper negative pressure adsorption space is formed between two adjacent upper annular belts.

[0012] As a further embodiment of the present invention, the upper active roller and the lower active roller are vertically flush, and the lower driven roller is located upstream of the upper driven roller on the fabric feeding side. The upper annular driving surface is larger than the lower annular driving surface. The fabric first contacts the lower annular driving surface to remove lint, and then feeds continuously along the lint removal gap, and negative pressure adsorption removes lint from the upper surface of the fabric.

[0013] As a further embodiment of the present invention, the upper suction box is arranged along the length of the roller body.

[0014] As a further embodiment of the present invention, a lifting mechanism for driving the second hair removal component to move vertically is provided above the second hair removal component.

[0015] As a further embodiment of the present invention, a fabric feeding support plate is provided on the fabric feeding side, and a first metal detector is provided on the fabric feeding support plate parallel to the axis of the roller body.

[0016] As a further embodiment of the present invention, the fabric outlet side is provided with a fabric outlet conveyor belt, and a fabric outlet support plate is provided between the second depilatory assembly and the fabric outlet conveyor belt. A second metal detector is provided on the fabric outlet support plate and is arranged parallel to the roller axis. After the fabric is depilated, it passes through the detection gap between the fabric outlet support plate and the second metal detector and enters the fabric outlet conveyor belt. The second metal detector is equipped with adjustable motors on both sides. The shaft of the adjustable motor is perpendicular to the two ends of the second metal detector. The synchronous movement of the adjustable motor drives the second water inlet detector to lift and lower to adjust the size of the detection gap.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This double-sided lint removal machine includes a frame, with one side of the frame designated as the fabric inlet side and the other side as the fabric outlet side. A double-sided lint removal assembly is provided between the fabric inlet side and the fabric outlet side. The double-sided lint removal assembly includes a first lint removal assembly and a liftable second lint removal assembly arranged vertically from bottom to top side by side. A lint removal gap is formed between the first lint removal assembly and the liftable second lint removal assembly to allow the fabric to pass through. The size of the lint removal gap is adjusted according to the fabric thickness. This achieves simultaneous lint removal on both sides of fabrics of various thicknesses.

[0018] The first lint removal component includes an upper lint removal surface, and the second lint removal component includes a lower lint removal surface. The upper and lower lint removal surfaces are parallel and facing each other, driving the fabric to move in a uniform, unidirectional stepping motion. The upper and lower lint removal surfaces respectively adhere closely to the two surfaces of the fabric and perform negative pressure adsorption for lint removal. The fabric passes through the upper and lower lint removal surfaces simultaneously and uniformly, removing fine lint, short lint, loose hair, and lint from the fabric surface and edges using negative pressure adsorption. Lint removal is thorough, the lint removal cycle is short, and there is no need for manual flipping for reverse lint removal. It is a one-time, highly efficient, and thorough lint removal process without secondary pollution. It also has the following advantages: (1) The first and second depilatory components drive the driven roller to rotate in the same direction through the active roller, which drives all the annular belts to rotate synchronously in the same direction, thereby driving the fabric to move synchronously and realize automatic continuous fabric feeding. The two adjacent lower annular belts form a lower negative pressure adsorption space; the entire surface of the fabric and the surrounding area of ​​the fabric are flattened and depilated, and the fabric is not easy to wrinkle. There is no blind spot for depilation of the fabric.

[0019] (2) The lower suction box and the upper suction box are directly facing the fabric surface through the negative pressure hole to perform bidirectional adsorption, keep the pressure on both sides of the fabric canceled, and keep the fabric in a horizontal adsorption state. When the vacuum pump is working, the suction box always maintains a constant negative pressure state, and the lint removal adsorption force on the fabric surface remains consistent, avoiding snagging, pilling, and also avoiding the risk of fabric deformation and reduced elasticity.

[0020] (3) The adsorbed lint is separated from the fabric surface in real time by the first and second fans through the pipeline. The suction is stable, the lint removal efficiency is high, the lint removal consistency is good, and there will be no secondary lint sticking. It also achieves efficient large-scale continuous lint removal.

[0021] (4) A lifting mechanism is provided above the second hair removal component to drive the second hair removal component to move vertically. The lifting mechanism drives the second hair removal component to move up and down vertically. The hair removal gap between the second hair removal component and the first hair removal component is adjusted according to the thickness of different fabrics. The hair removal gap is closely matched with the thickness of the fabric to ensure that the front and back of the fabric are completely and thoroughly removed while maintaining the characteristics of the fabric.

[0022] (5) A fabric feeding support plate is provided on the fabric feeding side, and a first metal detector is provided on the fabric feeding support plate parallel to the axis of the roller body. The fabric is fed into the de-hairing gap above the first metal detector. The first metal detector screens and detects the metal residue in the fabric for the first time, and removes the residual metal parts in time to ensure the smooth progress of the de-hairing process and subsequent processing.

[0023] (6) Finally, the metal parts are detected again by a second metal detector and removed in real time. The removal is more thorough and no rework or manual inspection is required, which saves a lot of costs and greatly shortens the processing cycle. (7) The adjustable gap motor synchronously drives the second water inlet detector to lift and adjust the size of the detection gap to meet the needs of different thicknesses of fabric. It can realize the processing of fabrics of various specifications, has strong versatility, and can meet the production of thick materials, thin materials, elastic materials and chemical fiber materials.

[0047] Please see the appendix Figure 6 - Appendix Figure 7 Above the second hair removal component 3 is a lifting mechanism 7 for driving the second hair removal component to move vertically. When the fabric thickness changes, the lifting mechanism is activated.

[0048] The lifting mechanism 7 includes a first lifting slider 703 and a second lifting slider 710 disposed on both sides of the second hair removal component. The second hair removal component is installed between the first and second lifting sliders. Vertical slide rails 706 are slidably fitted on both sides of the first and second lifting sliders. A first lifting motor 704 and a second lifting motor 705 are symmetrically disposed on both sides of the top of the first lifting slider. A third lifting motor 708 and a fourth lifting motor 707 are symmetrically disposed on both sides of the top of the second lifting slider.

A set of right-angle bevel gears 792 that mesh with each other are provided at both ends of the synchronous connecting rod. Each set of right-angle bevel gears is coaxially arranged with the first and second connecting rods respectively.

[0049] When the fabric to be de-haired becomes thinner, the worm gear reducer 791 of the lifting mechanism is activated, driving the synchronous connecting rod to rotate, which in turn drives the right-angle bevel gear to mesh, causing the first and second connecting rods to rotate synchronously. This drives the first lifting motor 704, the second lifting motor 705, the third lifting motor 708, and the fourth lifting motor 707 to start simultaneously. The worm gear reducer rotates in the forward direction, driving the lifting motor shaft to move synchronously downward, which in turn drives the second de-hairing component to move towards the first de-hairing component. The de-hairing gap decreases until it matches the fabric thickness. At this point, the worm gear reducer stops, and the de-hairing gap is adjusted to be smaller.

[0050] When the fabric to be de-haired becomes thicker, the worm gear reducer 791 of the lifting mechanism is activated, driving the synchronous connecting rod to rotate, which in turn drives the right-angle bevel gear to mesh, causing the first connecting rod 701 and the second connecting rod 702 to rotate synchronously. This drives the first lifting motor, the second lifting motor, the third lifting motor, and the fourth lifting motor to start simultaneously. The worm gear reducer 791 rotates in the opposite direction, driving the lifting motor shaft to move synchronously upward, which in turn drives the second de-hairing component 3 to move away from the first de-hairing component 2. The de-hairing gap increases until it matches the fabric thickness. At this point, the worm gear reducer stops, and the de-hairing gap is adjusted to be larger. Example 4

The fabric is fed into the de-hair removal gap above the first metal detector.

[0052] The fabric is fed into the defrosting gap 8 above the first metal detector. The first metal detector screens and detects any metal residue in the fabric for the first time, promptly removing any remaining metal parts to ensure the smooth progress of the defrosting process and subsequent processing. Example 5

[0053] Please see the appendix Figure 2 The fabric output side is provided with an output conveyor belt, and an output support plate is provided between the second dehairing component and the output conveyor belt. A second metal detector 121 is provided on the output support plate and is arranged parallel to the roller axis. After the fabric is dehaired, it passes through the detection gap between the output support plate and the second metal detector 121 and enters the output conveyor belt. After the fabric is de-linted, it is finally inspected again by the second metal detector 121, which adsorbs and removes metal parts in real time, making the removal more thorough and eliminating the need for rework and manual inspection. The second metal detector 121 is symmetrically equipped with adjustable motors 122 on both sides. The shaft end of the adjustable motor is perpendicular to the two ends of the second metal detector 121. The adjustable motor moves synchronously to drive the second water inlet detector to lift and adjust the size of the detection gap.

[0054] To meet the needs of fabrics of different thicknesses and to enable the production and processing of fabrics of various specifications, such as thick fabrics, thin fabrics, elastic fabrics, and chemical fiber fabrics, the adjustable gap motor 122 is started, and the synchronous motion drives the second water inlet detector to lift and adjust the size of the detection gap.
