Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary equipment for gauze processing, and particularly to a gauze suction system. Background Art

[0002] Gauze is woven from yarns. During the processing of gauze, there may be floating threads (some short threads attached to the gauze). Generally, the floating threads can be removed from the gauze by suction. For example, a suction box can be used. An inlet and an outlet opposite to the inlet are provided on the suction box. A suction fan is also connected to the top surface (or bottom surface) of the suction box. An opening is provided at a position opposite to the suction fan (or at other positions). During operation, the gauze passes through the suction box from the inlet and exits from the outlet. The suction fan operates to make external air enter the suction box through the opening, and then pass through the gauze. When the air passes through the gauze, it carries the floating threads away and is finally sucked away by the suction fan, achieving the purpose of cleaning the floating threads. However, during the actual operation process, if the suction fan is arranged above the gauze, a greater suction force is required to smoothly suck in the floating threads, which may cause the warp and weft threads on the gauze to be disordered. If the suction fan is arranged below the gauze, it may cause the gauze to sag severely and be accidentally sucked into the suction fan. Therefore, there are many faults during the operation process. Summary of the Invention

[0003] Aiming at the deficiencies existing in the prior art, the present invention provides a gauze suction system, which solves the problems that the warp and weft threads of the gauze may be disordered or the gauze may be sucked into the suction fan from below during the suction process in the prior art.

[0004] According to an embodiment of the present invention, a gauze suction system includes a suction box and a through box that horizontally penetrates the suction box. A rotating rod is further disposed above the through box inside the suction box, and a driver for driving the rotating rod to rotate self is disposed outside the suction box. A plurality of radiation needles extending from one end to the other end are fixedly arranged on the outer periphery of the rotating rod. A suction pipe is fixedly connected to the suction box, and the end of the suction pipe is connected to a suction fan. When the suction fan operates, the air flow inside the suction box enters the suction pipe after passing through the radiation needles; an inlet and an outlet are respectively disposed at both ends of the through box outside the suction box, an air outlet and an air inlet are respectively disposed on the top surface and the bottom surface of the through box inside the suction box, and an air inlet is further disposed on the bottom surface of the suction box. The suction fan is disposed above, and the gauze enters from the inlet and exits from the outlet. Different from the prior art, in this solution, a through box is provided on the suction box for the gauze to pass through. The gauze will not be displaced excessively upward or downward under the limitation of the suction box. At the same time, a rotating rod and the radiation needles thereon are further disposed inside the suction box. The radiation needles rotate with the rotation of the rotating rod and can be used for the floating threads to adhere to, and then are sucked away by the suction fan. In this way, even if the suction force provided by the suction fan is small, the floating threads can smoothly leave the gauze and be captured by the radiation needles. At the same time, this also avoids the confusion of the warp and weft threads of the gauze or the accidental falling of the gauze, and solves the problem that the warp and weft threads of the gauze may be confused or sucked into the suction fan from below during the suction process in the prior art.

[0005] Further, a plurality of support columns are disposed inside the through box from the inlet to the outlet.

[0006] Further, a pressing plate is vertically penetrated through the top surface at one end of the inlet of the through box, and the bottom surface of the pressing plate is an arc surface.

[0007] Further, an adjusting rod is detachably connected to the through box. The adjusting rod is vertically arranged, and an upper limiting ring and a lower limiting ring are fixedly arranged thereon. A transverse plate is fixedly connected to the end of the pressing plate outside the through box, and a through hole is provided on the transverse plate. The adjusting rod penetrates through the through hole, and the upper limiting ring and the lower limiting ring are respectively located above and below the through hole.

[0008] Further, two pressing columns are rotatably arranged inside the through box respectively close to the inlet and the outlet, and the two pressing columns are located above all the support columns.

[0009] Further, a plurality of protrusions are convexly arranged downward on the inner top surface of the through box from one end to the other end. The cross section of the protrusion is arc-shaped, and the air outlet includes a plurality of spaced-apart ones from the protrusions.

[0010] Further, two upper convex covers are respectively disposed on the top surface of the suction box close to the inlet and the outlet. The rotating rod includes a pair located directly below the two upper convex covers. The upper ends of the two upper convex covers are both connected to the suction pipe, and the radiation needles on the rotating rod are partially received into the upper convex covers.

[0011] Further, the part of the top surface of the suction box located between the two upper convex covers is recessed downward to form a lower convex part, and the bottom surface of the lower convex part is arc-shaped and is close to the top surface of the through box.

[0012] Further, the air inlet includes a pair located on both sides of the lower convex part.

[0013] Further, a pair of filter boxes that can respectively cover the two air inlets are slidably arranged on the suction box. The top surface of the filter box is open, and a through frame communicated with the air inlet is arranged on the bottom surface. A filter plate is also slidably arranged in the filter box. External air enters the filter box through the air inlet and then enters the suction box after passing through the filter plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] A through box for the gauze to pass through is arranged on the suction box. The gauze is limited up and down in the through box and will not be displaced excessively downward or upward accidentally. A rotating rod and radiation needles thereon are also arranged in the suction box. The radiation needles rotate with the rotation of the rotating rod and can be used for the attachment of floating threads, and then are drawn away by the suction fan. In this way, even if the suction force provided by the suction fan is small, the floating threads can smoothly leave the gauze and be caught by the radiation needles. At the same time, this also avoids the confusion of the warp and weft threads of the gauze or the accidental dropping of the gauze, and solves the problem that the warp and weft threads of the gauze may be confused or the gauze may be sucked into the suction fan from below in the prior art during the suction process.

Detailed implementation manner

[0025] The technical solutions in the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0027] Such as Figure 1-4As shown in the figure, this embodiment provides a gauze suction system, which includes a suction box 1 and a through box 2 that horizontally penetrates the suction box 1. Both ends of the through box 2 are located outside the suction box 1, and an inlet 42 and an outlet 43 are respectively provided on the end faces of the through box 2. The gauze 3 is introduced into the through box 2 from the inlet 42 and is led out from the outlet 43 after passing through the through box 2. During the whole process, the gauze 3 also passes through the suction box 1. Further, an air outlet 4 and an air inlet 5 are also provided on the through box 2, which are located inside the suction box 1 and on its top and bottom surfaces respectively. An air inlet 6 is provided on the bottom surface of the suction box 1. A suction pipe 7 is fixedly connected to the suction box 1, and the end of the suction pipe 7 is connected to a suction fan. When the suction fan operates, the air outside the suction box 1 enters through the air inlet 6, then enters the through box 2 through the air inlet 5, passes through the gauze 3, enters the suction box 1 again from the air outlet 4, and finally is drawn into the suction fan; furthermore, a rotating rod 8 is also provided inside the suction box 1 above the through box 2. A driver 9 for driving the rotating rod 8 to rotate is provided outside the suction box 1. A number of radiation needles 10 extending from one end to the other end are fixedly arranged on the outer periphery of the rotating rod 8. When the suction fan operates, the air flow inside the suction box 1 enters the suction pipe 7 after passing through the radiation needles 10. When the air passes through the gauze 3, it can carry the floating threads on the gauze 3 upward and leave. At the same time, the driver 9 drives the rotating rod 8 to rotate, and the rotating radiation needles 10 can provide attachment for the floating threads. The floating threads can move upward with the rotation of the radiation needles 10 and then be drawn into the suction fan. Such a setting enables the suction fan to provide a smaller suction force and still allows the floating threads to smoothly leave the gauze 3 and be captured by the radiation needles 10. At the same time, this also avoids the confusion of the warp and weft threads of the gauze 3 or the accidental sagging of the gauze 3, solving the problem that the warp and weft threads of the gauze 3 may be confused during the suction process in the prior art. At the same time, in this solution, the suction fan is arranged above, which also solves the problem that the gauze 3 may be sucked into the suction fan from below.

[0028] As Figure 1 、 2As shown, two upper convex covers 11 are provided on the top surface of the suction box 1, which are respectively close to the inlet 42 and the outlet 43. The rotating rod 8 includes a pair located directly below the two upper convex covers 11. Both upper ends of the two upper convex covers 11 are connected to the suction pipes 7. Part of the radiation needles 10 on the rotating rod 8 are received into the upper convex covers 11. The upper convex covers 11 allow part of the radiation needles 10 to be received / withdrawn during rotation. During the self-rotation of the rotating rod 8, when the radiation needles 10 are at the lowest position, they are close to the top surface of the box 2. At this time, the floating thread can move upward a small distance with the air and then contact the radiation needles 10. The radiation needles 10 can be set densely and are in a needle-like structure. In this way, the floating thread can adhere to the radiation needles 10 under the drive of the upward air, and then move smoothly upward with the rotation of the rotating rod 8 and the continuous upward movement of the air. Near the highest point, that is, where the upper convex cover 11 communicates with the suction pipe 7, as the air continues to move upward, most of the floating thread can be separated from the radiation needles 10 under the carrying of the air, and thus is drawn away by the suction fan through the suction pipe 7. The remaining small part continues to adhere to the radiation needles 10. At the same time, since the air moves upward throughout the process, the small part of the floating thread adhering to the radiation needles 10 also continuously approaches the rotating rod 8. Therefore, it can continuously supply the floating thread to adhere and transfer most of the floating thread to the suction pipe 7 within a certain period of time (such as the time required for the end of a round of suction operation), thereby ensuring the normal operation of the equipment;

[0029] In a further solution, the provided driver 9 can be a drive motor in the prior art. There are two groups of drive motors corresponding to the rotating rod 8, which can be respectively arranged at both ends of the suction box 1. In a further solution, the drive motor and the rotating rod 8 can be set as a whole that is detachable, which is convenient for cleaning the radiation needles 10 on the rotating rod 8. That is, on the side wall of the suction box 1 below one end of the upper convex cover 11, there is a circular hole 12 that can be enclosed with the upper convex cover 11, and the diameter of the circular hole 12 is slightly larger than the maximum circular diameter where the outer edges of all the radiation needles 10 are located. An installation plate 13 is detachably installed outside the circular hole 12. The driver 9 is fixed on the installation plate 13. One end of the rotating rod 8 rotates through the installation plate 13 and is fixedly connected to the rotating shaft of the drive motor, and the other end can be rotatably connected to the inner wall on the opposite side of the suction box 1. More specifically, a sleeve 14 that can be inserted and freely rotated by the end of the rotating rod 8 can be fixedly connected to the inner wall of the suction box 1. The sleeve 14 provides rotational support for the end of the rotating rod 8 away from the driver 9. In this way, when the driver 9 operates, the rotating rod 8 can stably perform self-rotation. When it is necessary to clean the radiation needles 10, the installation plate 13 is removed, and the driver 9 together with the installation plate 13 and the rotating rod 8 are taken out. The detachable connection of the installation plate 13 can be carried out using conventional connection methods, such as bolt locking;

[0030] In a further solution, a first extension cylinder 15 and a second extension cylinder 16 respectively located on both sides of the suction box 1 can also be fixedly connected between the upper convex cover 11 and the suction box 1. The mounting plate 13 and the first extension cylinder 15 are detachably connected, and the sleeve 14 is fixed in the second extension cylinder 16 (both ends of the first extension cylinder 15 are open, one end is connected to the mounting plate 13, and the other end communicates with the provided round hole 12, while one end of the second extension cylinder 16 is closed for fixing the sleeve 14, and the other end communicates with the inside of the suction box 1 and the upper convex cover 11). Such a setting can make both ends of the rotating rod 8 exceed both sides of the suction box 1, and further enable all the provided radiation needles 10 to completely cover the lower through box 2, providing the largest range for the floating yarn to adhere;

[0031] In a more detailed solution, the provided radiation needles 10 can also be in an arc-shaped structure. At the same time, when the driver 9 operates, the self-rotation direction of the rotating rod 8 is the same as the bending direction of the arc-shaped structure. In this way, when the rotating rod 8 rotates, the radiation needles 10 can provide an auxiliary effect similar to scooping up, and cooperate with the air movement to make it easier for the floating yarn to adhere to the radiation needles 10. At the same time, at the connection between the upper convex cover 11 and the suction pipe 7, it provides an effect similar to throwing upwards, and cooperates with the air movement to more smoothly separate most of the floating yarn from the radiation needles 10.

[0032] As Figure 1 、 5 shown, the part of the top surface of the suction box 1 located between the two upper convex covers 11 is recessed downward by 30 to form a lower convex part 17. The bottom surface of the lower convex part 17 is arc-shaped and is close to the top surface of the through box 2. That is, the provided lower convex part 17 divides the space of the suction box 1 above the through box 2 into front and rear parts. The corresponding exhaust fans are assisted by two rotating rods 8 respectively to make the floating yarn be sucked away. At the same time, on both sides of the lower convex part 17 are arc-shaped transition surfaces 18. The provided air inlets 6 include a pair located on both sides of the lower convex part 17. Air enters from the air inlets 6 on both sides, then passes through the through box 2 and contacts the arc-shaped transition surface 18 upwards, and then is guided by the arc-shaped transition surface 18 to move more smoothly towards the rotating rod 8. At the same time, the bending direction of the provided radiation needles 10 is exactly opposite to the arc-shaped transition surface 18, so that the floating yarn can more smoothly adhere to the radiation needles 10.

[0033] As Figure 1 、 3As shown in FIGS. 5 and 6, a pair of filter boxes 19 that can respectively cover the two air inlets 6 are also slidably arranged on the suction box 1. The top surface of the filter box 19 is open, and a through frame 44 communicating with the air inlet 6 is arranged on the bottom surface. A filter plate 20 is also slidably arranged in the filter box 19. External air enters the filter box 19 through the air inlet 6 and then enters the suction box 1 after passing through the filter plate 20. The filter box 19 arranged below the through box 2 in the suction box 1 can filter the inhaled air, thereby avoiding bringing in external impurities additionally. Specifically, the filter plate 20 can be a three-dimensional grid structure. For example, the filter plate 20 can include an outer frame 21 and multiple layers of steel meshes 22 detachably fixed inside the outer frame 21. The steel meshes 22 are provided with equally sized mesh holes, and the mesh holes located below are larger than those located above, so that the impurities in the air passing through the filter plate 20 are effectively intercepted. More specifically, a plurality of supporting blocks 23 can be fixedly connected to the inner wall of the outer frame 21. For example, two groups of supporting blocks 23 are respectively fixedly arranged on the inner walls of the opposite sides. The two groups of opposite supporting blocks 23 are used for connecting a steel mesh 22. For example, the steel mesh 22 is detachably locked on the supporting blocks 23 through a locking rod 24 (such as a bolt). There is a certain distance between the upper and lower steel meshes 22, and the steel mesh 22 itself has a certain flexibility. Therefore, during later disassembly, it can be carried out one by one, which is convenient for cleaning and maintenance.

[0034] Furthermore, one end of the outer frame 21 is also fixedly connected with a connecting plate 25. The outer frame 21 is slidably arranged with the filter box 19, while the connecting plate 25 is detachably connected with the sliding box through a positioning rod 26 (such as a threaded connection). The arranged filter box 19 and the internal filter plate 20 and other structures have a relatively large weight and can maintain a certain stability after being inserted into the suction box 1. The arranged filter plate 20 is fixedly formed into a whole with the filter box 19 through the connecting plate 25 and the positioning rod 26. During cleaning, first pull out the whole filter box from the suction box 1, and then disassemble the filter plate 20 for cleaning, or directly disassemble the filter plate 20 and then pull it out for cleaning. Furthermore, one end of the arranged filter box 19 is located outside the suction box 1 and is fixedly connected with a pair of ear plates 27. The filter box 19 can be conveniently pulled through the two ear plates 27.

[0035] As Figure 1 , 5 As shown in FIGS. 7 and 8, a vertical plate 28 is also fixedly connected to the middle section of the suction box 1, and support plates 29 are also connected to both ends. The suction box 1 is enabled to stand on the ground through the vertical plate 28 and the support plates 29. The vertical plate 28 also extends into the suction box 1 and is fixedly connected with the through box 2. In this way, the vertical plate 28 also provides support for the middle section of the through box 2. The air inlet 6 and the filter box 19, etc. are respectively located on both sides of the vertical plate 28, and a recess 30 is also arranged on the vertical plate 28 for the end of the filter box 19 to abut against, so as to provide a more stable support and positioning effect for the filter box 19.

[0036] AsFigure 1-7 As shown, the inlet 42 and the outlet 43 provided in this solution are both of relatively small height, while the air inlet 6 is larger. When the exhaust fan operates, air mainly enters through the air inlet 6. More specifically, a number of support columns 31 are arranged in the through box 2 from the inlet 42 to the outlet 43. These support columns 31 are on the same horizontal plane and provide upward support for the gauze 3, so that the air inlet 5 on the through box 2 can be set larger. For example, the air inlet 5 can be a pair located on both sides of the lower convex part 17. Such an air inlet 5 allows air to enter the through box 2 from below to a greater extent, rather than entering through the inlet 42 and the outlet 43 at both ends of the through box 2. When the gauze 3 passes through the through box 2, auxiliary tools can be used. For example, a pair of traction strips are connected to the end of the gauze 3. The two traction strips can be made of steel and have a length greater than the overall length of the through box 2, so that the traction strips can pass through the through box 2 smoothly, and thus the gauze 3 can also pass through smoothly;

[0037] Furthermore, a pressing plate 32 is vertically penetrated and arranged on the top surface of one end of the inlet 42 on the through box 2. The bottom surface of the pressing plate 32 is an arc surface. When the pressing plate 32 moves vertically, the arc surface at the bottom can be raised / lowered. When the traction strip of the gauze 3 passes through, the arc surface is raised to avoid obstruction. After the traction strip has completely passed through and is removed, the arc surface can be lowered so that the pressing plate 32 presses the gauze 3 below the top surface of the first support column 31. When the exhaust fan operates, the gauze 3 will move slightly upward. The provided pressing plate 32 limits the entry of the gauze 3 at this position to prevent the gauze 3 from pressing against the top surface of the through box 2 upward at this position. More specifically, an adjusting rod 33 is detachably connected to the through box 2. The adjusting rod 33 is vertically arranged and an upper limit ring 34 and a lower limit ring 35 are fixedly arranged thereon. The end of the pressing plate 32 located outside the through box 2 is fixedly connected with a cross plate 36 and a through hole 37 is arranged on the cross plate 36. The adjusting rod 33 passes through the through hole 37. The upper limit ring 34 and the lower limit ring 35 are respectively located above and below the through hole 37. More specifically, an installation block 38 is fixedly connected to the top surface of the through box 2 outside the suction box 1. The installation block 38 is located below the cross plate 36 and is provided with a threaded hole 45. The lower end of the adjusting rod 33 is provided with a threaded section that is threadedly engaged with the threaded hole 45. The lower end of the adjusting rod 33 is threadedly connected to the threaded hole 45. At the same time, the distance between the upper limit ring 34 and the lower limit ring 35 is greater than the thickness of the cross plate 36, that is, the cross plate 36 will not contact the upper limit ring 34 and the lower limit ring 35 at the same time, and neither of them will pass through the provided through hole 37. In this way, when the adjusting rod 33 rotates upward, it drives the lower limit ring 35 to move upward and contact the cross plate 36. Continuing to rotate will lift the cross plate 36 upward, causing the pressing plate 32 to move upward. Vice versa, the pressing plate 32 will move downward;

[0038] Furthermore, two pressing columns 39 are rotatably arranged inside the passing box 2 near the inlet 42 and the outlet 43 respectively, and the two pressing columns 39 are located above all the supporting columns 31. The arranged pressing columns 39 are above the gauze 3. When the exhaust fan operates, upper limits are provided at both ends of the gauze 3 to prevent the gauze 3 from moving upward excessively and sticking to the top surface of the passing box 2. The arranged supporting columns 31 and pressing columns 39 are both of round rod structures and can be fixedly connected or rotatably connected to the passing box 2. The movement of the gauze 3 is mainly achieved by external traction. The direct contact surfaces of the supporting columns 31 and the pressing columns 39 with the gauze 3 are smooth arc surfaces, which have little influence on the gauze 3. In a further solution, a plurality of protrusions 40 arranged from one end to the other end are convexly arranged on the inner top surface of the passing box 2. The cross-section of the protrusions 40 is arc-shaped, and the air outlet 4 includes a plurality of them arranged at intervals with the protrusions 40. The bottom surfaces of these protrusions 40 are also arc-shaped, which also prevents the gauze 3 from directly sticking to the inner top surface of the passing box 2 like the pressing columns 39. The arranged air outlet 4 is arranged at intervals with the protrusions 40, and they are both strip-shaped. In this way, the floating threads of the gauze 3 can gradually pass upward through the air outlet 4 during the movement process, and at the same time, it will not directly stick to the inner top surface of the passing box 2. Furthermore, the end of the passing box 2 where the inlet 42 is arranged can be of an open structure, which is convenient for the traction strip to be inserted into the passing box 2. A pair of guiding plates 41 can also be fixedly connected to the top surface at the open end. The pressing plate 32 slides through between the two guiding plates 41, so that the up and down movement of the pressing plate 32 is smoother. At the same time, the pressing plate 32 and the guiding plates 41 also play a role in blocking a large amount of air from being inhaled into the passing box 2 at this position.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
