Description
Technical Field
[0001] The utility model relates to the technical field of cloth dyeing machines, in particular to a feeding device of a cloth dyeing machine. Background Art
[0002] Immersion dyeing is a commonly used method in cloth dyeing. During the dyeing process, the cloth needs to be immersed in a dye vat to allow the cloth to absorb the dye in the dye vat, thereby achieving the purpose of coloring the cloth.
[0003] In the conventional cloth dyeing process, the cloth is directly sent into the dye vat. There are lint and dust on the untreated cloth. When the cloth directly enters the dye vat, the lint on the cloth will float in the dye vat. When the cloth leaves the dye vat, the floating lint is easy to stick to the cloth and flow to the next dehydration process with the cloth, and then the cloth is dried. The presence of lint can easily cause contamination of the dye in the dye vat. The lint adsorbed on the cloth will also affect the coloring of the cloth and reduce the dyeing effect of the cloth. The cloth needs to be cleaned of lint before entering the dye vat.

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] The present embodiment provides a feeding device for a cloth dyeing machine, which is mainly used to transport cloth into a dyeing vat and process the lint on the cloth, thereby solving the problem that the presence of lint affects the coloring effect of the cloth.
[0027] Before the cloth enters the dyeing machine or dyeing vat, the cloth needs to be separated from the lint to prevent the lint from entering the dyeing vat or dyeing machine with the cloth.
[0028] like Figure 1 , Figure 2 and Figure 3 As shown, it includes a box body 1, wherein a feed port 11 for cloth to enter and a discharge port 12 for cloth to leave the box body 1 are provided in the box body 1, and auxiliary rollers 13 are installed at the positions of the feed port 11 and the discharge port 12, wherein the cloth enters the inner cavity of the box body 1 through the auxiliary roller 13 at the feed port 11, and the cloth leaves the inner cavity of the box body 1 through the auxiliary roller 13 at the discharge port 12, wherein the setting of the auxiliary roller 13 prevents the cloth from being scratched against the edge of the feed port 11 or the discharge port 12, thereby reducing the risk of cloth snagging.
[0029] In order to advance the cloth in the box 1, in this embodiment, as Figure 3 and Figure 7 As shown, a feed roller 14 and a first motor 191 for driving the feed roller 14 to rotate are rotatably installed in the inner cavity of the box 1, wherein the feed roller 14 is located downstream of the feed inlet 11, and the cloth abuts against the peripheral wall of the feed roller 14.
[0030] In order to improve the effect of cloth movement, in this embodiment, Figure 3 and Figure 7 As shown, a discharge roller 15 and a second motor 192 for driving the discharge roller 15 to rotate are also installed in the inner cavity of the box body 1. The discharge roller 15 is located upstream of the discharge port 12, wherein the cloth abuts against the peripheral wall of the discharge roller 15.
[0031] It is worth noting that, during the movement of the cloth, the first motor 191 and the second motor 192 have the same rotation speed and jointly drag the cloth forward.
[0032] In order to prevent the cloth from falling downwards between the feed roller 14 and the discharge roller 15 due to the action of gravity, in this embodiment, Figure 3 As shown, a plurality of guide rollers 16 are further provided in the inner cavity of the box body 1, wherein the cloth passes through the guide rollers 16 in sequence and extends toward the side of the front discharge port 12 in a wave shape.
[0033] In order to clean the lint on the cloth, in this embodiment, Figure 1 and Figure 2 As shown, a blowing hood 2 is installed on the side wall of the box body 1, and a suction hood 5 is installed on the other side wall of the box body 1, which also includes a fan 7, wherein the fan 7 is fixedly installed on the box body 1, the suction port of the fan 7 is connected to the negative pressure port 53 of the suction hood 5, the air outlet of the fan 7 is connected to the air inlet 22 of the blowing hood 2, and a filtering mechanism for filtering lint is also provided in the suction hood 5.
[0034] Through the above arrangement, the fan 7 supplies air to the blowing hood 2, thereby blowing the wind into the inner cavity of the box body 1. At this time, the wind blows the cloth in the inner cavity of the box body 1 to shake, and then the fluff flies in the inner cavity of the box body 1. Since the air suction port of the fan 7 is connected to the negative pressure port 53 of the suction hood 5, the gas and fluff in the box body 1 gather in the suction hood 5, and the fluff entering the suction hood 5 is blocked by the filtering mechanism, thereby preventing the fluff from continuing to enter the inner cavity of the box body 1 from the fan 7 and the blowing hood 2, thereby achieving the cleaning of the fluff on the cloth.
[0035] In order to realize the installation of the air suction hood 5, in this embodiment, as shown in FIG. Figure 1 and Figure 6 As shown, a second mounting groove 18 is provided on the side wall of the box body 1, wherein the air suction hood 5 is installed in the second mounting groove 18, the air suction part of the air suction hood 5 is located in the inner cavity of the box body 1, and the rest of the air suction hood 5 extends out of the box body 1 through the second mounting groove 18.
[0036] In order to realize the installation of the blowing hood 2, in this embodiment, as Figure 2 and Figure 5 As shown, a first mounting groove 17 is further provided on the side wall of the box body 1 , wherein the blowing cover 2 is installed in the first mounting groove 17 .
[0037] In order to improve the cleaning effect of the fluff, in this embodiment, Figure 3 , Figure 7 and Figure 8 As shown, the peripheral walls of the feed roller 14 and the discharge roller 15 are provided with reverse spiral lines, and the reverse spiral lines are utilized to stretch the cloth in the inner cavity of the box body 1, thereby reducing wrinkles on the cloth and fully exposing the fluff in the inner cavity of the box body 1, thereby facilitating the blowing of the fluff off the cloth and improving the cleaning effect of the fluff.
[0038] In order to achieve the effect of cleaning the lint, the conventional operation is to install a filter in the channel of the suction hood 5 and use the filter to filter the lint. As the lint accumulates on the filter, even if the fan 7 continues to run, the suction force at the suction hood 5 will be reduced, and the amount of air sent by the fan 7 to the blowing hood 2 will also be reduced synchronously. In severe cases, the fan 7 will be burned out.
[0039] Therefore, in this embodiment, if Figure 5 As shown, a dust-proof net perforation 51 is provided on the air suction hood 5, and the filtering mechanism includes a ring-shaped dust-proof net 63, wherein the dust-proof net 63 passes through the dust-proof net perforation 51 and circulates in the dust-proof net perforation 51, and the dust-proof net 63 blocks the channel of the air suction hood 5, and also includes a rotating mechanism for driving the dust-proof net 63 to rotate.
[0040] Through the above arrangement, the dust-proof net 63 is driven to circulate and rotate in the dust-proof net perforation 51 by the rotating mechanism, so that the area of the dust-proof net 63 used to block the passage of the air suction hood 5 can be continuously changed, thereby solving the problem of the dust-proof net 63 being blocked.
[0041] Specifically, the rotating mechanism includes a first transmission shaft 61, a second transmission shaft 62 and a third motor 64 for driving the first transmission shaft 61 to rotate, wherein an annular dustproof net 63 is sleeved on the outside of the first transmission shaft 61 and the second transmission shaft 62, and the inner side wall of the dustproof net 63 is in contact with the peripheral wall of the first transmission shaft 61 and the second transmission shaft 62; the rotating mechanism can also be regarded as a pulley transmission, except that the conveyor belt in the traditional pulley transmission is replaced by the dustproof net 63.
[0042] In order to clean the fluff on the dustproof net 63 in time, in this embodiment, Figure 6 As shown, a scraper 54 is also installed in the air duct of the air suction hood 5, wherein the scraper 54 is arranged on the front side of the dustproof net 63, and the tip of the scraper 54 is abutted against the outer wall of the dustproof net 63. In this embodiment, the third motor 64 drives the dustproof net 63 to rotate in a counterclockwise direction through the first transmission shaft 61 and the second transmission shaft 62, wherein the scraper 54 is fixedly installed on the bottom wall of the air duct of the air suction hood 5. As the dustproof net 63 rotates, the fluff connected to the dustproof net 63 will be scraped off by the scraper 54.
[0043] In order to store the scraped fluff, in this embodiment, Figure 6 As shown, a waste collection chamber 52 is also provided on the air duct of the air suction hood 5, wherein a detachable shielding plate 521 is provided at the bottom end of the waste collection chamber 52, and the shielding plate 521 can open or close the bottom of the waste collection chamber 52, so as to facilitate the removal of the fluff from the waste collection chamber 52. It is worth noting that the waste collection chamber 52 is located upstream of the scraper 54, and the scraper 54 is provided with an inclined slope, wherein the bottom end of the slope points to the waste collection chamber 52, as shown in FIG. Figure 6 As shown, when the fluff is peeled off from the dustproof net 63, the fluff slides along the inclined surface of the scraper 54 into the waste collection chamber 52, completing the collection of the fluff.
[0044] Since the dustproof net perforation 51 is set to connect the air duct of the air suction hood 5 with the outside, the pressure inside the air suction hood 5 will drop. Therefore, in this embodiment, Figure 6 As shown, a sealing cover 65 is also provided on the air suction hood 5, wherein the dust screen perforation 51 is arranged in the chamber formed by the sealing cover 65. At this time, the first transmission shaft 61 and the second transmission shaft 62 are both rotatably connected to the inner wall of the chamber formed by the sealing cover 65, and the third motor 64 is fixedly installed on the sealing cover 65.
[0045] In order to further improve the effect of separating the lint from the cloth, in this embodiment, Figure 2 , Figure 4 and Figure 5 As shown, the side wall of the blowing hood 2 is provided with a rotating shaft 21, wherein the rotating shaft 21 is rotatably connected to the side wall of the first mounting groove 17, so that the blowing hood 2 can swing up and down around the rotating shaft 21, and also includes a driving mechanism for driving the blowing hood 2 to swing up and down.
[0046] Through the above-mentioned arrangement, the driving mechanism is used to drive the blow hood 2 to swing back and forth up and down. At this time, the airflow at the blowing port of the blow hood 2 will swing in a wave-like manner, blowing through the side of the cloth, so that the airflow alternately passes through the top and bottom of the cloth, causing the cloth to shake when moving, and then shaking off the lint from the cloth.
[0047] Specifically, in this embodiment, Figure 2 , Figure 5 and Figure 8 As shown, the driving mechanism includes a rotating shaft 31, a cam 32, a first pulley 33, a second pulley 34 and a transmission belt 35, wherein the rotating shaft 31 is rotatably mounted on the side wall of the box body 1, the first pulley 33 is fixedly mounted on the rotating shaft 31, the second pulley 34 is fixedly mounted on the output shaft of the first motor 191, the transmission belt 35 is sleeved on the outside of the first pulley 33 and the second pulley 34, and the cam 32 is fixedly mounted on the rotating shaft 31, wherein the rotating shaft 31 is located at the bottom of the blow hood 2, and the outer edge of the cam 32 abuts against the bottom wall of the blow hood 2 extending out of the box body 1. It is worth noting here that the point where the cam 32 contacts the blow hood 2 deviates from the axis of the rotating shaft 21.
[0048] Through the above arrangement, when the first motor 191 rotates, it can drive the rotating shaft 31 to rotate through the second pulley 34, the transmission belt 35 and the first pulley 33, and then drive the cam 32 to rotate. Since the outer edge of the cam 32 abuts against the bottom wall of the blow hood 2, it can push the blow hood 2 to swing up and down around the rotating shaft 21.
[0049] In order to enable the bottom wall of the blowing cover 2 to continuously abut against the outer edge of the cam 32, in this embodiment, as shown in FIG. Figure 2 and Figure 5 As shown, a push plate 41 located above the blow hood 2 is fixedly provided on the side wall of the box body 1, and also includes a compression spring 42, wherein one end of the compression spring 42 abuts against the top wall of the blow hood 2, and the other end of the compression spring 42 abuts against the bottom wall of the push plate 41. The compression spring 42 can be used to continuously abut the blow hood 2 and the cam 32.
[0050] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
