Description

Technical Field

[0001] This application relates to the technical field of polyester-cotton fabric production equipment, and in particular to a polyester-cotton fabric conveying device with a self-cleaning function. Background Technology

[0002] During the conveying process, a large amount of debris remains on the surface and in the gaps between the fibers of polyester-cotton fabric. This debris mainly includes cotton lint, loose threads, and other impurities generated during production. In actual production, these residual debris can lead to several adverse consequences. On the one hand, the debris adhering to the surface of the polyester-cotton fabric severely affects the appearance quality of the product, causing defects and lowering its grade. On the other hand, the residual debris may affect the work efficiency in subsequent processing stages, such as dyeing and cutting.

[0003] A search revealed Chinese Patent Publication No. CN119018662A, which discloses a conveying device for producing polyester-cotton fabric. The device includes a conveying unit with a conveyor belt and a bearing surface for supporting and transporting polyester-cotton fabric. At least one adsorption tube is provided on the conveyor belt and communicates with the bearing surface. The conveying unit also has an installation space and a mounting platform within the installation space. A suction device is movable on the mounting platform, moving in a direction parallel to the conveying direction of the conveying unit, and has an suction end. A first air pipe is movable on the suction end and communicates with it. After moving, the first air pipe communicates with the adsorption tube and moves with the conveyor belt, or it disconnects from the adsorption tube.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: the existing conveying devices cannot clean polyester-cotton fabrics, causing debris from the fabric to affect subsequent processes. To address this problem, this application utilizes a rotating roller with through holes, an adsorption mechanism within the roller, and a beating mechanism on the first stand to effectively remove debris from the surface of the polyester-cotton fabric and between fibers, improving cleaning efficiency and effectiveness, and preventing debris from affecting subsequent processes. Utility Model Content

[0005] In order to avoid debris affecting the technical effect of subsequent processes, this application provides a polyester-cotton fabric conveying device with self-cleaning function.

[0006] This application provides a self-cleaning polyester-cotton fabric conveying device, employing the following technical solution: It includes a base plate, on which a first, second, and third upright are mounted; the first, second, and third uprights are rotatably connected to a first rotating roller, a second rotating roller, and a third rotating roller, respectively; the first, second, and third rotating rollers have identical structures, each being a cylindrical body with multiple through holes on its circumferential wall; each of the first, second, and third rotating rollers is equipped with an adsorption mechanism; the adsorption mechanism includes a connecting part fixedly mounted on the corresponding upright, and an air extraction pipe fixedly mounted on the connecting part, the air extraction pipe being connected to an air pump; the circumferential wall of the air extraction pipe has multiple air extraction holes; a beating mechanism is mounted on the first upright. The beating mechanism beats the polyester-cotton fabric, loosening the debris within it, which is then adsorbed by the adsorption mechanism.

[0007] Optionally, an air suction hood is fixedly installed on the outer wall of the air extraction pipe. The air suction hood is a hood structure, and the opening surface of the air suction hood is adapted to the inner wall of the first rotating roller.

[0008] Optionally, the opening of the suction hood faces the contact area between the rotating roller and the polyester-cotton fabric.

[0009] Optionally, the slapping mechanism includes a first rotating rod rotatably connected to the first upright, and multiple nylon ropes are connected to the peripheral wall of the first rotating rod, with a rubber ball fixedly installed at the end of each nylon rope.

[0010] Optionally, a first motor is fixedly mounted on the first support frame, and the output shaft of the first motor is coaxially and fixedly connected to the first rotating rod.

[0011] Optionally, the horizontal height of the second rotating roller is lower than that of the first and third rotating rollers.

[0012] Optionally, a first toothed ring is fixedly sleeved on the outer wall of the third rotating roller, and a second motor is fixedly mounted on the third upright. The output shaft of the second motor is coaxially fixedly mounted with a second gear that meshes with the first toothed ring.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model, by setting up a beating mechanism, uses the rubber ball at the end of the nylon rope to periodically beat the surface of the polyester-cotton fabric, which can loosen the debris hidden in the gaps between the fibers; in conjunction with the adsorption mechanism inside the rotating roller, under the action of the air pump, the air extraction pipe forms a negative pressure, and the air suction hood concentrates and sucks in the debris at the through hole of the rotating roller and discharges it, which can thoroughly remove the debris from the surface of the polyester-cotton fabric and the gaps between the fibers, and avoid it from affecting subsequent processes.

[0015] 2. This utility model uses a second rotating roller with a lower horizontal height than the first and third rotating rollers to create a "concave" path during the conveying of the polyester-cotton fabric, increasing the contact area with the three rotating rollers; at the same time, the suction hood opening faces the contact area between the rotating rollers and the polyester-cotton fabric, which can more accurately adsorb debris, greatly improving the cleaning efficiency and effect of the polyester-cotton fabric and reducing secondary pollution from debris.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1-5 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0023] This application discloses a polyester-cotton fabric conveying device with self-cleaning function; such as... Figure 1As shown, the system includes a horizontally positioned base plate 1. A first upright 2, a second upright 3, and a third upright 4 are sequentially fixed to the base plate 1 along the polyester-cotton fabric conveying direction (the uprights can be welded from steel plates or bolted to the base plate 1 to ensure structural stability). A first rotating roller 5 is rotatably connected to the first upright 2 via bearings, a second rotating roller 6 is rotatably connected to the second upright 3 via bearings, and a third rotating roller 7 is rotatably connected to the third upright 4 via bearings. The first rotating roller 5, the second rotating roller 6, and the third rotating roller 7 have identical structures, all being hollow cylinders with one open end and multiple circular through holes evenly distributed on their circumferential walls. The horizontal height of the second rotating roller 6 is lower than that of the first rotating roller 5 and the third rotating roller 7, creating a "concave" path for the polyester-cotton fabric during conveying, increasing the contact area with the three rotating rollers, and improving the cleaning effect.

[0024] Please see Figure 2 and Figure 3 Each rotating roller is equipped with an adsorption mechanism for adsorbing debris from the surface and interior of the polyester-cotton fabric. Taking the adsorption mechanism in the first rotating roller 5 as an example (the adsorption mechanisms in the second and third rotating rollers 7 have the same structure), the adsorption mechanism includes a connecting part 8 fixedly installed inside the first support 2 (the connecting parts 8 of the adsorption mechanisms in the second rotating roller 6 and the third rotating roller 7 are fixedly connected to the second support 3 or the third support 4, respectively). An air extraction pipe 9 is vertically fixed on the connecting part 8. One end of the air extraction pipe 9 extends into the interior of the first rotating roller 5, and the other end is connected to an air pump (not shown in the figure) through a hose. The air extraction pipe 9 is located on a section of the peripheral wall inside the rotating roller, and multiple air extraction holes 10 are evenly opened therein.

[0025] Please see Figure 3 The outer wall of the suction pipe 9 is also fixedly fitted with a suction hood 11; the suction hood 11 has an arc-shaped structure, and the curvature of its opening surface is perfectly matched with the curvature of the inner wall of the first rotating roller 5, and the opening direction of the suction hood 11 is directly facing the area where the polyester-cotton fabric is attached to the rotating roller.

[0026] With the above structure, when the air pump is started, a negative pressure is formed in the air extraction pipe 9, and the air suction hood 11 can concentrate and suck in the debris at the through hole of the rotating roller, and then discharge it to the collection device (such as a filter bag) through the air extraction pipe 9, so as to avoid secondary pollution of the debris.

[0027] Please see Figure 4 and Figure 5The first support frame 2 is equipped with a beating mechanism for beating the surface of the polyester-cotton fabric to loosen the debris hidden in the fiber gaps, making it easier for the subsequent adsorption mechanism to remove it. Specifically, it includes a first rotating rod 12 that is rotatably connected to the first support frame 2 and is horizontally arranged; multiple nylon ropes 13 are uniformly fixed to the axial side of the peripheral wall of the first rotating rod 12; a rubber ball 14 is fixed to the end of each nylon rope 13 away from the rotating rod; a first motor 15 (optional servo motor) is fixed to the outside of the first support frame 2, and the output shaft of the first motor 15 is coaxially fixed to one end of the first rotating rod 12 through a coupling.

[0028] When the first motor 15 starts, it drives the first rotating rod 12 to rotate. The nylon rope 13 drives the rubber ball 14 to periodically beat the surface of the polyester-cotton fabric passing through the first rotating roller 5, so that the debris is removed from the fiber and the subsequent adsorption efficiency is improved.

[0029] Please see Figure 4 The third rotating roller 7 acts as the driving roller to transport the polyester-cotton fabric. A first toothed ring 16 is fixedly sleeved on the outer peripheral wall of one end of the third rotating roller 7. A second motor 17 (optional geared motor) is fixed on the outer side of the third upright 4. A second gear 18 is coaxially fixed on the output shaft of the second motor 17. The second gear 18 meshes with the first toothed ring 16. When the second motor 17 starts, it drives the third rotating roller 7 to rotate through gear transmission, thereby driving the polyester-cotton fabric to pass through the first rotating roller 5, the second rotating roller 6, and the third rotating roller 7 in sequence to achieve continuous transport.

[0030] The implementation principle of a self-cleaning polyester-cotton fabric conveying device according to an embodiment of this application is as follows:

[0031] The polyester-cotton fabric enters from above the first rotating roller 5, and passes around the first rotating roller 5, the second rotating roller 6 (because the second rotating roller 6 is low in height, the polyester-cotton fabric forms a depression here, increasing the contact area with the roller body), and the third rotating roller 7 in sequence, forming a continuous conveying path;

[0032] Start the second motor 17, which drives the third rotating roller 7 to rotate through gear transmission, causing the polyester-cotton fabric to move at a set speed; start the first motor 15, which drives the first rotating rod 12 to rotate, and the rubber ball 14 periodically pats the surface of the polyester-cotton fabric, loosening the debris in the fiber gaps.

[0033] When the air pump is started, the suction pipes 9 in the three rotating rollers all form negative pressure. The suction hood 11 sucks in the loosened debris and surface floating debris after beating through the through holes of the rotating rollers and discharges them to the collection device through the suction pipes 9. The cleaned polyester-cotton fabric is output from the third rotating roller 7 and enters the subsequent processing steps.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
