Description
TECHNICAL FIELD
[0001] The utility model relates to the carding machine field in the spinning system, especially to a dust and impurity separation device suitable for a cotton grabber. BACKGROUND
[0002] The carding flow in the prior art has included a multifunctional separator, which includes an S-shaped cotton conveying pipeline, a metal spark detection device, an airflow balance separation component and two sets of heavy impurity separation components, can effectively remove heavy objects, metals and dust and impurities in the raw materials, improve the purification effect of the fiber raw material, and thus improve the quality and efficiency of the subsequent spinning process.
[0003] Please refer to Figure 1 , Figure 1 is a typical multifunctional separator suitable for the carding flow in the prior art. The textile raw material first passes through the horizontal section of the spark metal detection device 100 in the separator, then enters the exclusion device after a 180° turn, and continues to move forward through the airflow balance separation component 600 installed in a vertical manner in the negative pressure balance area; enters the first set of heavy impurity separation components 500 on the arc-shaped cotton conveying pipeline at the end of the airflow balance separation component 600, and the impurities enter the first impurity falling trolley 400; the fiber continues to move forward into the second set of heavy impurity separation components 200 arranged on the horizontal cotton conveying pipeline, and the impurities enter the second impurity falling trolley 300, which needs to rely on the suction of the rear machine table to be smoothly output. The fiber is transported out after two 180° turns in the separator, which can effectively remove metals, heavy impurities and dust, but the energy consumption is very large.
[0004] In addition, although the existing heavy separator can effectively remove heavy impurities and metal debris from the raw material, they are usually large in size, for example, the size of some devices can reach 2776mmx1750mmx3470mm. The layout of such large equipment on the production line needs to consider the problem of bale discharge of the cotton grabber and the safe operation of the cotton grabbing arm, so a certain safety distance must be maintained to avoid collision and influence between devices. Due to the large size of the equipment, a safety distance of at least 5 meters away from the cotton grabber is required. The textile raw material needs to be conveyed by the fan, first reaching a certain height, and then running horizontally for a distance to enter the cotton inlet of the separator. In this process, a part of the air volume may be lost, affecting the conveying efficiency and the cleanliness of the raw material.
[0005] The existing blowing-carding line has not yet been equipped with a device with multiple functions of removing heavy objects, metals and dust at the position of the conveying fan outlet of the reciprocating picking machine. Although the existing multifunctional separator can effectively remove metals, heavy impurities and dust from the textile raw materials, this process involves a complex internal structure, a large floor area, and a safety distance from other devices when arranging the process, and the installation and equipment are not flexible. Due to the mechanical structure of the device itself, the textile raw materials need to be turned over by 180 degrees twice in the machine to be removed by different components, and the multiple large-scale bending causes large air volume loss and high energy consumption.
[0006] In summary, how to effectively solve the problems of complex internal structure, multiple large-scale bending leading to high energy consumption and the like is an urgent problem for the technical personnel in the field. Practical new type content

[0041] The inlet of the heavy impurity removing component 23 is directly connected with the outlet of the cotton conveying fan 1, the heavy impurity removing component 23 is located at the lowermost position, and the heavy impurities are more easily deposited at the lower position due to the gravity.

[0044] The heavy object removing component 23 and the dust and impurity removing component 21 are stacked from bottom to top, the metal removing component 25 is arranged in the arc-shaped channel 27 connecting the heavy object removing component 23 and the dust and impurity removing component 21, and the arrangement mode that the heavy object removing component 23, the metal removing component 25 and the dust and impurity removing component 21 are sequentially arranged from bottom to top in space is formed, the three working components are seamlessly connected, and the mechanical structure is compact.
[0045] The dust and impurity separating device 2 achieves various performances while the space occupied area is minimized, the configuration is flexible, and the dust and impurity separating device 2 can be directly placed at the outlet of the cotton grabbing fan 1 of the cotton grabbing machine.
[0046] On the basis of the above various specific embodiments, the inlet of the heavy object removing component 23 is lower than the outlet, the inlet and the outlet of the dust and impurity removing component 21 are flush, and the outlet of the heavy object removing component 23 and the inlet of the dust and impurity removing component 21 are tangentially connected with the arc-shaped channel 27.
[0047] In one specific embodiment, the conveying channel of the heavy object removing component 23 is inclined upward from the inlet to the outlet, that is, the inlet of the heavy object removing component 23 is lower than the outlet, which is consistent with the conveying trend of the conveying channel of the dust and impurity separating device 2 from low to high, the track of the output airflow of the cotton grabbing fan is utilized to reduce energy consumption, the textile raw material enters the heavy object removing component 23 in a high-speed jetting manner, and the conveying channel is prevented from being blocked.
[0048] After the material passes through the arc-shaped channel 27, it enters the horizontal dust removal component 21, which has an inlet and an outlet that are flush with each other. The material passes smoothly through the dust removal component 21, and under the action of the airflow, the fine dust and a portion of the short fiber and other light impurities in the textile raw material are removed.
[0049] Moreover, the outlet of the heavy removal component 23 and the inlet of the dust removal component 21 are tangentially connected to the arc-shaped channel 27, and the entire conveying channel of the dust separation device 2 is smoothly connected, reducing energy loss and ensuring smooth conveying.
[0050] Based on the above embodiments, the heavy removal component 23, the dust removal component 21, and the dust collection box 22 of the dust removal component 21 are sequentially arranged from bottom to top.
[0051] In one embodiment, the dust removal component 21 is located directly above the heavy removal component 23, the bottom of the heavy removal component 23 is the bottom of the entire machine, and the upper part of the heavy removal component 23 is the bottom of the dust removal component 21. The running channel between them is the metal removal component 25. The external dimensions are 874mm x 630mm x 1852mm (length x width x height), and the floor area is only 11.6% of the existing equipment. The device is small in size and compact in mechanical structure, and occupies a small area.
[0052] In the above embodiments, this design from bottom to top not only saves space, but also ensures that impurities are effectively separated and collected according to their weight and size, thereby improving the efficiency of the entire blowing and carding process and the quality of the final product. In addition, this design also helps to simplify the operation and maintenance of the equipment, as each component is optimally configured according to the physical properties and removal sequence of impurities.
[0053] Based on the above embodiments, the heavy removal component 23 includes a housing with an inlet and an outlet, a toothed dust bar 231 arranged at the inlet in the housing, and a deflection vane 232 arranged in the housing. The deflection vane 232 has a plate surface that forms a conveying channel, and the toothed dust bar 231 is located above the plate surface of the deflection vane 232. A plurality of impurity removal channels are formed between the deflection vane 232 and the inner wall of the housing, and one of the impurity removal channels is arranged below the toothed dust bar 231.
[0054] In one embodiment, the heavy object removing component 23 is mainly composed of a shell, a toothed dust bar 231 and a deflection vane 232, which are arranged in the shell. The shell has an inlet and an outlet. The textile material enters the heavy object removing component 23 through the inlet under the action of the fan impeller. The toothed dust bar 231 is arranged at the inlet of the shell and above the plate surface of the deflection vane 232. The upper wall of the shell and the plate surface form a conveying channel of the heavy object removing component 23. The material passes through the conveying channel to the outlet and then enters the arc-shaped channel 27. The outer periphery of the deflection vane 232 and the inner wall of the shell form a heavy object falling channel.
[0055] The toothed dust bar 231 is sawtooth-shaped and has a plurality of teeth, which can disperse the lumpy textile material, expose the small stones, small nuts, screws and heavy objects such as dead pieces in the textile material, remove the impurities in the textile material through the dust bar impact and airflow separation, and make the impurities fall into the heavy object falling channel and the textile material pass through the conveying channel normally.
[0056] At the same time, the outer periphery or the middle of the deflection vane 232 and the inner wall of the shell form a plurality of heavy object falling channels. When the textile material passes through the conveying channel, the speed of the textile material and the impurities is different, the textile material and the impurities are separated, and when the textile material passes through the conveying channel, the large heavy objects fall into the heavy object falling channel under the action of gravity and are discharged into the heavy object falling collection box 22, so as to remove the large heavy objects such as stones and metals in the textile material.
[0057] In the above embodiment, the textile material and the impurities are separated through the joint action of the toothed dust bar 231 and the deflection vane 232 during the forward movement process. The heavy objects fall into the heavy object falling collector under the action of gravity, so as to effectively remove the heavy impurities and avoid the heavy impurities entering the subsequent channel, thereby improving the impurity removal efficiency.
[0058] In one preferred embodiment, an observation window 26 is arranged on the shell of the heavy object removing component 23.

[0059] On the basis of the above embodiments, the plate surface of the deflection vane 232 is inclined upward from the inlet to the outlet, that is, the conveying channel of the heavy object removing component 23 is inclined upward from the inlet to the outlet. When the textile material passes through the conveying channel, the plate surface of the deflection vane 232 supports the textile material, matches the overall conveying trend of the conveying channel of the dust and impurity separating device 2 from low to high, utilizes the trajectory of the output airflow of the blowing machine fan, reduces the energy loss, and prevents the conveying channel from being blocked.
[0060] On the basis of the above various embodiments, the metal removing component 25 comprises a magnet assembly 251, which is arranged on the outer circular inner wall of the arc-shaped channel 27 and located at the corner with the largest bending angle of the arc-shaped channel 27.

[0062] In operation, the textile raw material moves along the outer circle of the arc-shaped channel 27 under the action of the centrifugal force under the action of the fan. In order to better adsorb the foreign matter, the magnet assembly 251 is arranged on the outer circle of the arc-shaped channel 27 and located at the corner with the largest bending angle, so that the textile raw material can better contact and collide with the magnet assembly 251 under the action of the largest centrifugal force, and the ferromagnetic foreign matter in the textile raw material is removed by the magnet assembly 251 to ensure the safety of the subsequent equipment.
[0063] In a preferred embodiment, the arc-shaped channel 27 is provided with an observation window 26 and a door lock device, so that the user can timely check the state of the magnet adsorbing foreign matter through the observation window 26, and open the door lock device installed on the circular arc channel to clean the foreign matter adsorbed on the magnet.

[0067] In a specific embodiment, the dust-removing component 21 is composed of a deflector 211 and a triangular dust bar 212. The deflector 211 is installed by outside bolts and adjusted to change the running direction of the textile material in the conveying channel. The deflector 211 is located on the upper wall of the cavity and faces the triangular dust bar 212, so that the textile material can collide with the triangular dust bar 212 better.
[0068] The triangular dust bar 212 is horizontally arranged and removes the fine dust and part of the short fibers in the textile material by the collision of the textile material with the working angle of the triangular dust bar 212. The working angle of the triangular dust bar 212 can be controlled by the outside adjusting handle 28.

[0076] In one embodiment, the dirt collecting box 22 is provided with a guide rail 222, and the sliding plug 221 is inserted into the guide rail 222 and can slide along the guide rail 222. When the sliding plug 221 is slid to above the dirt opening, the dirt collecting box 22 is isolated from the heavy object removing part 23 and the dirt removing part 21; when the sliding plug 221 is slid away from the dirt opening, the dirt collecting box 22 is connected to the heavy object removing part 23 and the dirt removing part 21, which is convenient to operate.
[0077] When the textile raw material passes through the heavy object removing part 23 and the dirt removing part 21, the heavy dirt is separated from the textile raw material under the joint action of the dust rod and the heavy object, and then enters the dirt collecting box 22 through the dirt passage. When the impurities reach the cleaning scale line, the sliding plug 221 is moved through the guide rail 222 to cover the dirt opening of the dirt collecting box 22, so that the inside of the machine always maintains a positive pressure state. At this time, the cleaning window is opened for cleaning, and the space in the dirt collecting box 22 is ensured to be sufficient. After cleaning, the cleaning window is reset, and the sliding plug 221 is extracted again or moved away from the dirt opening of the dirt collecting box 22, so as to ensure that the impurities fall into the dirt collecting box 22 again.
