Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal of precision opening cotton machines, and more specifically, to an impurity removal device for a wide-width precision opening cotton machine. Background Art

[0002] A wide-width precision opening cotton machine is a mechanical device used in the textile industry to process raw cotton. This machine is mainly used to open large pieces of cotton raw materials and clean impurities, and at the same time convert them into a form suitable for subsequent processing (such as spinning, etc.). The wide-width precision opening cotton machine is characterized by its large processing width, which can improve production efficiency.

[0003] Among them, the dust rod impurity dropping area in the precision opening cotton machine is a key area for separating and removing impurities in cotton. The interaction between the dust rod and the beater will generate a tearing force, which helps to loosen the fibers. At the same time, impurities will fall through the gaps between the dust rods due to gravity. The impurities falling to the bottom of the dust dropping area will be sucked away by the air suction devices on both sides of the dust dropping area, achieving the effect of removing dust and impurities.

[0004] However, since the air suction devices in the dust rod impurity dropping area of the precision opening cotton machine are arranged on both sides, the negative pressure in the middle area and the area at a relatively far distance is small. As a result, some larger and heavier impurities cannot be sucked away and will accumulate. After a period of time, it is easy to cause blockage of the air suction pipeline, which will further lead to failures of the precision opening cotton machine and affect the normal operation of the precision opening cotton machine; at the same time, it requires frequent inspections and handling by staff, with a large workload and a lot of time consumption.

[0005] Therefore, it is necessary to provide an impurity removal device for a wide-width precision opening cotton machine to solve the above technical problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an impurity removal device for a wide-width precision opening cotton machine to solve the above technical problems.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An impurity removal device for a wide-width precision opening cotton machine is arranged in the impurity dropping area of the main body of the precision opening cotton machine, and further includes:

[0009] A baffle and a blowing head are both arranged on the impurity dropping area, and the blowing head is located in the middle position of the impurity dropping area and close to one side of the baffle;

[0010] A push plate is arranged on the baffle, and a driving mechanism is further arranged on the baffle for driving the push plate to move horizontally;

[0011] A pressing plate and a transmission mechanism are both arranged on the push plate. When the push plate moves, the pressing plate will be driven to move synchronously through the transmission mechanism.

[0012] Further, the driving mechanism includes:

[0013] The lead screw and the limit slide bar are both rotatably arranged on the baffle. Connecting plates are provided on both sides of the push plate. One connecting plate is threadedly connected to the lead screw, and the other connecting plate is slidably connected to the limit slide bar;

[0014] A driving member is arranged on the baffle, and the output end of the driving member is connected to the lead screw.

[0015] Further, the transmission mechanism includes:

[0016] A bracket is arranged on the push plate. A first rotating shaft is rotatably arranged on the bracket, and a first straight gear is provided at the end of the first rotating shaft;

[0017] A first toothed plate is slidably arranged on the push plate and meshes with the first straight gear. The pressing plate is connected to the first toothed plate;

[0018] A linkage member is arranged on the baffle for driving the first rotating shaft to rotate.

[0019] Further, the linkage member includes:

[0020] A second rotating shaft is rotatably arranged on the bracket. A second straight gear and a third straight gear are respectively provided at both ends of the second rotating shaft, and the second straight gear meshes with the first straight gear;

[0021] A second toothed plate is arranged on the baffle and meshes with the third straight gear.

[0022] Further, a chute is formed on the outer wall of the push plate, and a slide bar slidably connected to the chute is arranged on the first toothed plate.

[0023] Further, an inner connecting plate is movably inserted into the pressing plate. A plurality of adjustment holes are formed in the inner connecting plate, and fastening bolts adapted to the adjustment holes are threadedly connected to the pressing plate.

[0024] Further, an avoidance groove adapted to the air blowing head is formed on the push plate.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0026] 1. In this solution, the air blowing head on the impurity dropping area intermittently blows air to the middle area, so as to blow the dust and impurities falling into the middle area of the impurity dropping area to both sides, and then the impurity suction devices on both sides suck away the blown impurities, thus solving the problem that the negative pressure in the middle area is small and large and heavy impurities cannot be sucked away, and the dust and impurity accumulation in the middle area of the impurity dropping area can be eliminated.

[0027] 2. In this solution, the driving mechanism drives the push plate to push the dust and impurities that fall far away from the air suction device towards the air suction device. It can also prevent some stubborn impurities from adhering to the surface of the impurity dropping area. With the combined action of the blowing head and the push plate, the accumulation of impurities in the impurity dropping area can be greatly avoided, enabling the impurities to be smoothly sucked away. The impurity removal effect is good, thereby preventing the air suction pipeline from being blocked due to the accumulation of impurities, reducing the occurrence of faults in the precision opener, and ensuring its normal operation. Moreover, it will greatly reduce the number of inspections and treatments by staff, significantly reducing the workload, saving a large amount of time, and having high work efficiency.

[0028] 3. In this solution, when the push plate moves, the pressing plate will be driven to move synchronously through the cooperation of the transmission mechanism. That is, when the push plate moves towards the air suction device, the pressing plate will move down along the push plate to press down on the impurities, greatly restricting the scattering of the dust and impurities, and being able to better concentrate the impurities for suction, further preventing the remaining of impurities. The impurity removal effect is good. At the same time, the pressing plate can also scrape off the impurities on the surface of the push plate, preventing the situation of residual impurities adhering to its surface, and having strong practicability.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0038] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, then the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0039] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, then the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0040] Please refer to Figures 1-6 , a waste removal device for a wide-width fine opener, which is arranged in the waste removal area 2 of the main body 1 of the fine opener, and further includes: a baffle 3 and a blowing head 4, both of which are arranged on the waste removal area 2, the blowing head 4 is located in the middle of the waste removal area 2 and close to one side of the baffle 3; a pusher plate 5, which is arranged on the baffle 3, and a driving mechanism 6 is also arranged on the baffle 3 for driving the pusher plate 5 to move horizontally; a pressing plate 7 and a transmission mechanism 8, both of which are arranged on the pusher plate 5, and when the pusher plate 5 moves, the pressing plate 7 will be driven to move synchronously through the transmission mechanism 8.

[0041] When the main body 1 of the precision opener is working normally, the impurities in the cotton will normally fall into the impurity removal area 2, and the impurities will be sucked away by the air suction devices on both sides of the impurity removal area 2. At the same time, the air blowing heads 4 on the impurity removal area 2 intermittently blow air into the middle area, so as to blow the dust and impurities falling into the middle area of the impurity removal area 2 to both sides, and then the impurities blown over are sucked away by the air suction devices on both sides, thus solving the problem that the negative pressure in the middle area is small and large and heavy impurities cannot be sucked away, and the dust and impurity accumulation in the middle area of the impurity removal area 2 can be eliminated. At the same time, after working for a certain period of time, the push plate 5 can be driven by the driving mechanism 6 to move back and forth. At this time, the push plate 5 moves towards the air suction device inlet direction, and the dust and impurities falling at a place far from the air suction device are pushed towards the air suction device by the push plate 5, so that the air suction device can suck away these dust and impurities, and the situation that some stubborn impurities adhere to the surface of the impurity removal area 2 can be prevented. Thus, through the cooperation of the air blowing head 4 and the push plate 5, the accumulation of impurities in the impurity removal area 2 can be greatly avoided, the impurities can be smoothly sucked away, the impurity removal effect is good, and further the situation that the air suction pipeline is blocked due to the accumulation of impurities can be prevented, the occurrence of faults of the precision opener can be reduced, and its normal operation can be ensured; and the number of inspections and treatments by the staff will also be greatly reduced, the workload is significantly reduced, a large amount of time is saved, and the work efficiency is high.

[0042] When the push plate 5 moves, the pressing plate 7 will be driven to move synchronously through the transmission mechanism 8, that is, when the push plate 5 moves towards the air suction device, at this time the pressing plate 7 will be driven to descend through the transmission mechanism 8. The impurities pushed by the push plate 5 can be pressed down by the descending of the pressing plate 7, which greatly limits the scattering of the dust and impurities, can better concentrate the impurities, and further enables the impurities to be sucked away by the air suction device, further preventing the residue of impurities, and the impurity removal effect is good; at the same time, the pressing plate 7 can also scrape off the impurities on the surface of the push plate 5 to prevent the situation of adhesion and residue of impurities on its surface, and the practicability is strong. On the contrary, when the push plate 5 moves back to the initial position, the pressing plate 7 will also rise accordingly, waiting for the next step of continuous work.

[0043] The push plate 5 is provided with an avoidance groove 14 adapted to the air blowing head 4. When the push plate 5 moves, the air blowing head 4 will pass through the avoidance groove 14, which can avoid the interference of the push plate 5 on the air blowing head 4, and the air blown out by the air blowing head 4 later will also pass through the avoidance groove 14 to make the impurities in the middle area move towards both sides.

[0044] In this embodiment, preferably, please refer to Figures 1-5, the driving mechanism 6 includes a lead screw 61 and a limit slide bar 62, both rotatably arranged on the baffle 3. Connecting plates 63 are provided on both sides of the push plate 5.

The driving member 64 in this application can be a servo motor. After starting the driving member 64, it will drive the lead screw 61 to rotate. After the lead screw 61 rotates, it will drive the connecting plate 63 thereon to move, and the connecting plate 63 on the other side will move along the limit slide bar 62. Thus, the push plate 5 will be driven to move horizontally through the connecting plate 63. By driving the lead screw 61 to rotate forward and backward through the driving member 64, the push plate 5 will be driven to move back and forth. When the push plate 5 moves towards the air suction device, it will push the impurities towards the air suction device.

[0045] In this embodiment, preferably, please refer to Figures 2-6 , the transmission mechanism 8 includes a bracket 81 arranged on the push plate 5. A first rotating shaft 82 is rotatably arranged on the bracket 81, and a first spur gear 83 is provided at the end of the first rotating shaft 82; a first toothed plate 84 is slidably arranged on the push plate 5 and meshes with the first spur gear 83, and the pressing plate 7 is connected to the first toothed plate 84; a linkage member 85 is arranged on the baffle 3 for driving the first rotating shaft 82 to rotate. When the push plate 5 moves, it will drive the first rotating shaft 82 to rotate through the cooperation with the linkage member 85. The first rotating shaft 82 will drive the first spur gear 83 to rotate, and the first spur gear 83 will drive the first toothed plate 84 and the pressing plate 7 to move up and down, so as to Figure 3 take the orientation as an example to illustrate. When the push plate 5 moves to the right, that is, moves towards the air suction device, it will drive the first rotating shaft 82 and the first spur gear 83 to rotate counterclockwise through the linkage member 85, and the first spur gear 83 will drive the first toothed plate 84 and the pressing plate 7 to move down; vice versa. When the push plate 5 moves to the left and returns to the initial position, the first spur gear 83 rotates clockwise to drive the first toothed plate 84 and the pressing plate 7 to move up.

Take Figures 3-4 as an example. When the push plate 5 moves to the right, it will drive the third spur gear 853 to rotate along the second toothed plate 854. At this time, the third spur gear 853 and the second rotating shaft 851 rotate clockwise, and the second rotating shaft 851 will drive the second spur gear 852 to rotate clockwise. The second spur gear 852 will drive the first spur gear 83 to rotate counterclockwise, and further drive the first toothed plate 84 and the pressing plate 7 to move down. Vice versa.
