Description

Technical Field

[0001] This application relates to the technical field of textile product processing aids, and particularly to a lint collection device for a raising machine. Background Art

[0002] Raising is a process in the textile industry. Through the friction between the fabric and the emery paper of the raising machine, a layer with a feeling of short fluff layer is formed on the fabric surface, which not only retains the original characteristics but also endows the fabric with a new style.

[0003] The patent document with the application number 202120389772.4 discloses a single-sided and double-sided raising machine, which includes a raising mechanism and a discharging mechanism. The raising mechanism includes a front raising mechanism and a back raising mechanism. The front raising mechanism successively includes a first fabric tensioning roller, a first raising device, a first carding device, a first fabric discharging roller and a first guiding roller. The back raising mechanism successively includes a second guiding roller, a second fabric tensioning roller, a second raising device, a second carding device, a second fabric discharging roller, a third guiding roller and a fourth guiding roller.

[0004] In view of the above related technologies, during the process of raising the fabric by the raising device, a large amount of lint will inevitably be generated. The designed single-sided and double-sided raising machine sucks lint through a lint suction structure installed on the carding roller. However, as the use time prolongs, the mesh cover installed on the carding roller will be blocked by lint. If not cleaned in time, it will affect the lint collection efficiency. Summary of the Invention

[0005] In order to achieve self-cleaning of the mesh cover to improve the lint collection efficiency, this application provides a lint collection device for a raising machine.

[0006] The lint collection device for a raising machine provided by this application adopts the following technical solutions:

[0007] A lint collection device for a raising machine includes a filter screen, a collection box, an air vent hose, a differential pressure control valve, a clogging cleaning mechanism, a piston mechanism, a conversion mechanism and a suction mechanism;

[0008] The filter screen is installed in the collection box and divides the collection box into two chambers;

[0009] The differential pressure control valve is installed on the air vent hose, and the air vent hose is communicated with the lower chamber of the filter screen;

[0010] The piston mechanism includes an adjusting cylinder, a piston disc and a linkage member. The adjusting cylinder is installed on the collection box. The piston disc slides in the adjusting cylinder and divides the inner cavity of the adjusting cylinder into a rod chamber and a rodless chamber;

[0011] The linkage is installed on the piston disk, and the linkage is connected to the blockage clearing mechanism and the conversion mechanism;

[0012] The conversion mechanism is installed on the adjusting cylinder and is used to alternately connect the ventilation hose with the rod chamber or the rodless chamber;

[0013] The air suction mechanism is connected to the collection frame and is used to keep the chamber below the filter screen in a negative pressure state.

[0014] By adopting the above technical solutions, when the air suction mechanism works, the chamber below the filter screen is kept in a negative pressure state. The lint generated by brushing is affected by the pressure and enters the collection frame through the filter screen and then enters the air suction mechanism. As the use time prolongs, the lint clogs the filter screen. However, the air suction mechanism continues to work, causing the pressure in the chamber below the filter screen to gradually decrease. When the pressure difference between the chamber below the filter screen and the atmospheric pressure reaches the set value, the pressure difference control valve opens, causing the pressure in the rod chamber to decrease. The piston disk slides along the axial direction of the adjusting cylinder and drives the blockage clearing mechanism and the conversion mechanism to move through the linkage. The blockage clearing mechanism scatters the lint clogging the filter screen. At the same time, the conversion mechanism connects the ventilation hose with the rodless chamber. Until the next blockage occurs, the above actions are repeated to complete another blockage clearing. In this way, the automatic blockage clearing of the filter screen is realized; the designed lint collection device of the brushing machine is convenient for sucking the lint generated by brushing through the collection frame, the filter screen and the air suction mechanism, is convenient for driving the blockage clearing mechanism to work through the ventilation hose, the pressure difference control valve, the piston mechanism and the conversion mechanism, and is convenient for scattering the lint clogging the filter screen through the blockage clearing mechanism, thereby realizing the automatic blockage clearing of the filter screen to improve the lint collection efficiency.

[0015] In a specific feasible implementation scheme, the linkage includes a piston rod and a linkage frame;

[0016] The piston rod extends out and is slidably connected to the adjusting cylinder, and the extending section of the piston rod is connected to the blockage clearing mechanism;

[0017] The linkage frame is connected to the extending section of the piston rod, and the linkage frame is connected to the conversion mechanism.

[0018] By adopting the above technical solutions, the designed linkage can drive the movement of the linkage frame and the blockage clearing mechanism through the piston rod, and can drive the conversion mechanism through the linkage frame.

[0019] In a specific feasible implementation scheme, the conversion mechanism includes a fixed cylinder, a partition plate and a sliding sleeve;

[0020] The fixed cylinder is connected to the adjusting cylinder, and the axial direction of the fixed cylinder is the same as that of the adjusting cylinder;

[0021] The partition is connected to the fixed cylinder and divides the inner cavity of the fixed cylinder into a first chamber and a second chamber. The first chamber is arranged close to the collection box. The first chamber is communicated with the rodless chamber, and the second chamber is communicated with the rod chamber;

[0022] The sliding sleeve is connected to the linkage frame. The sliding sleeve slides on the fixed cylinder. The inner cavity of the sliding sleeve is communicated with the ventilation hose, and the inner cavity of the sliding sleeve can be communicated with the first chamber or the second chamber.

[0023] By adopting the above technical solution, when the pressure difference between the chamber below the filter screen and the external environment reaches the set value, the pressure difference control valve opens, so that the pressure in the second chamber decreases, and further the pressure in the rod chamber decreases. The piston rod extends to drive the clogging clearing mechanism to move, completing the clogging clearing work of the filter screen. At the same time, the piston rod drives the sliding sleeve to move through the linkage frame, so that the ventilation hose is communicated with the first chamber, and the first chamber is linked with the rodless chamber until the filter screen is clogged again, causing the piston disc to reset and completing the clogging clearing of the filter screen again; the designed conversion mechanism can easily form the first chamber and the second chamber through the fixed cylinder and the partition, and the ventilation hose can be easily communicated with the first chamber or the second chamber through the sliding sleeve, thereby realizing the pushing and resetting actions of the piston disc.

[0024] In a specific feasible embodiment, a strip-shaped groove is axially formed on the fixed cylinder, and the inner cavity of the sliding sleeve is communicated with the first chamber or the second chamber through the strip-shaped groove.

[0025] By adopting the above technical solution, the designed strip-shaped groove can facilitate improving the error tolerance rate of the movement range of the piston disc.

[0026] In a specific feasible embodiment, the clogging clearing mechanism includes a fixed shaft, a linkage gear and a cleaning strip;

[0027] The fixed shaft is vertically connected to the filter screen;

[0028] The linkage gear is sleeved on the fixed shaft. The linkage gear is rotatably connected to the fixed shaft and meshes with the piston rod;

[0029] The cleaning strip is connected to the linkage gear and abuts against the top wall of the filter screen.

[0030] By adopting the above technical solution, when the piston rod extends, it drives the linkage gear to rotate. While the linkage gear rotates, it drives the cleaning strip to rotate around the fixed shaft. While the cleaning strip rotates, it scatters the debris clogging the filter screen; the designed clogging clearing mechanism can easily transfer the power of the piston rod to the cleaning strip through the fixed shaft and the linkage gear, and the cleaning strip can easily complete the action of scattering the debris clogging the filter screen.

[0031] In a specific feasible implementation, a conical shielding cover is connected to the fixed shaft, and the linkage gear is directly below the conical shielding cover.

[0032] By adopting the above technical solution, the designed conical shielding cover facilitates reducing the possibility of lint falling onto the linkage gear.

[0033] In a specific feasible implementation, a covering cover is connected to the collection box, and a passage cavity is provided at the connection between the collection box and the covering cover.

[0034] By adopting the above technical solution, the designed covering cover can accommodate the wool grinding device in its inner cavity, reducing the possibility of lint escaping.

[0035] In a specific feasible implementation, the air suction mechanism includes a vacuum cleaner and an air suction pipe;

[0036] One end of the air suction pipe is connected to the vacuum cleaner, and the other end is connected to the collection box, and the inner cavity of the air suction pipe is communicated with the chamber below the filter screen.

[0037] By adopting the above technical solution, the designed air suction mechanism facilitates keeping the chamber below the filter screen under negative pressure and completing lint collection through the cooperation of the vacuum cleaner and the air suction pipe.

[0038] In summary, the present application includes at least one of the following beneficial technical effects:

[0047] An embodiment of the present application discloses a lint collection device for a brushing machine.

[0049] Referring to Figure 2 , the filter screen 1 is bolted to the collection box 2, and the filter screen 1 divides the inner cavity of the collection box 2 into two chambers. The chamber below the filter screen 1 is set as a negative pressure chamber. The suction mechanism 8 includes a vacuum cleaner 81 and a suction pipe 82. One end of the suction pipe 82 is communicated with the negative pressure chamber, and the other end is communicated with the vacuum cleaner 81; one end of the ventilation hose 3 is communicated with the negative pressure chamber, and the other end is connected to the conversion mechanism 7, and the differential pressure control valve 4 is installed on the ventilation hose 3.

[0050] Referring to Figure 2 and Figure 3, the piston mechanism 6 includes an adjusting cylinder 61, a piston disc 62 and a linkage member 63. The adjusting cylinder 61 is bolted to the collection frame 2. The piston disc 62 slides within the adjusting cylinder 61, and the piston disc 62 divides the inner cavity of the adjusting cylinder 61 into a rod chamber 64 and a rodless chamber 65. The rod chamber 64 is arranged on the side close to the collection frame 2. The linkage member 63 includes a piston rod 631 and a linkage bracket 632. The piston rod 631 is coaxially connected to the piston disc 62. The piston rod 631 passes through and is slidably connected to the front cylinder head of the adjusting cylinder 61. The linkage bracket 632 is welded to the extended section of the piston rod 631.

[0051] Referring to Figure 2 and Figure 3 , the conversion mechanism 7 includes a fixed cylinder 71, a partition plate 72 and a sliding sleeve 73. The fixed cylinder 71 is bolted to the adjusting cylinder 61, and the fixed cylinder 71 is axially aligned with the adjusting cylinder. The partition plate 72 is located within the inner cavity of the fixed cylinder 71, and the partition plate 72 divides the inner cavity of the fixed cylinder 71 into a first chamber 74 and a second chamber 75. The first chamber 74 is arranged close to the collection frame 2. The first chamber 74 is communicated with the rodless chamber 65 through a pipeline. The second chamber 75 is communicated with the rod chamber 64 through a pipeline.

[0052] Referring to Figure 2 and Figure 3 , the sliding sleeve 73 is welded to the linkage bracket 632, and the sliding sleeve 73 slides on the fixed cylinder 71. Two strip-shaped grooves 711 are formed on the fixed cylinder 71. The strip-shaped grooves 711 are arranged along the axial direction of the adjusting cylinder 61. The inner cavity of the sliding sleeve 73 is communicated with the end of the ventilation hose 3 far from the negative pressure chamber, and the inner cavity of the sliding sleeve 73 is communicated with the first chamber 74 or the second chamber 75 through the strip-shaped grooves 711.

[0053] Referring to Figure 2 and Figure 3 , the blockage clearing mechanism 5 includes a fixed shaft 51, a linkage gear 52 and a cleaning strip 53. The fixed shaft 51 is perpendicularly welded to the filter net 1. The linkage gear 52 is coaxially sleeved on the fixed shaft 51, and the linkage gear 52 is rotatably connected to the fixed shaft 51. The linkage gear 52 meshes with the rack section on the piston rod 631. The cleaning strip 53 is welded to the linkage gear 52, and the cleaning strip 53 abuts against the top wall of the filter net 1. In order to reduce the falling of lint onto the linkage gear 52, a conical shielding cover 54 is coaxially welded on the fixed shaft 51, and the linkage gear 52 is directly below the conical shielding cover 54.

[0054] The implementation principle of the lint collection device of a napping machine in an embodiment of the present application is as follows: an external power supply provides electrical energy for the operation of the vacuum cleaner 81. The vacuum cleaner 81 maintains a negative pressure in the negative pressure chamber through the suction pipe 82. The lint generated by napping enters the vacuum cleaner 81 through the filter screen 1 under the action of pressure. As the usage time prolongs, the lint clogs the filter screen 1, causing the pressure in the negative pressure chamber to gradually decrease until the pressure difference between the pressure in the negative pressure chamber and the atmospheric pressure reaches a set value, and the differential pressure control valve 4 opens.

[0055] After the differential pressure control valve 4 opens, the negative pressure chamber is communicated with the inner cavity of the sliding sleeve 73 through the ventilation hose 3. The inner cavity of the sliding sleeve 73 is communicated with the second chamber 75 through the strip-shaped groove 711. The second chamber 75 is communicated with the rod chamber 64 through a pipeline, causing the air pressure in the rod chamber 64 to decrease. The pressure difference between the rod chamber 64 and the rodless chamber 65 drives the piston disk 62 to move. While the piston disk 62 moves, it drives the piston rod 631 to extend and drives the cleaning strip 53 to disperse the lint clogging the filter screen 1 through the linkage gear 52. At the same time, the piston rod 631 drives the sliding sleeve 73 to slide on the fixed cylinder 71 through the linkage frame 632, causing the inner cavity of the sliding sleeve 73 to be communicated with the first chamber 74 through the strip-shaped groove 711 until the filter screen 1 is clogged by lint again, and the above process is repeated to complete the cleaning action of the filter screen 1.

[0056] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
