Cloth discharging squeezing water recycling mechanism of dye vat

Abstract

When cloth needs to penetrate through a fixed roller and a movable pressing roller, limitation on the vertical state of a supporting track arm is relieved through a fixing assembly, so that the upper end of the supporting track arm is in a rotatable state, and at the moment, the movable roller is pushed, so that the cloth is squeezed and recycled. The rotating shaft at the upper end of the supporting track arm can rotate, so that the distance between the fixed roller and the movable roller is increased, and cloth can conveniently penetrate out; meanwhile, when the cloth is squeezed, through the arrangement of a lifting seat, a guide shaft, a compression spring and an adjusting knob, the movable compression roller can move upwards after being stressed when meeting the position with the large thickness of the cloth, the problem that the cloth conveying resistance is too large can be solved, and through the action of the compression spring and the movable roller, it can be guaranteed that when the cloth is pressed tightly, the cloth is squeezed tightly; the problem of insufficient cloth squeezing can be solved.

Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing equipment, in particular to a cloth-discharging squeezing water recovery mechanism of a dye vat. Background Art

[0002] Cloth dyeing is a dyeing method in which the dyed fabric is immersed in a dye solution, and the dye is uniformly dyed onto the textile through the circulation of the dye solution and the relative movement of the dyed object. The equipment used for dyeing is a dye vat, and in the prior art, the dye vat is mostly an overflow dye vat (also called an overflow dyeing machine).

[0003] A water-squeezing and water-recovery mechanism is provided at the cloth outlet end of the dyeing vat, which can squeeze out the dye liquid adsorbed on the cloth and return it to the dyeing vat. For example, a Chinese patent with the authorization announcement number CN207062563U and the authorization announcement date of March 2, 2018 discloses a water-squeezing and water-recovery device for a dyeing machine, which can squeeze and recover water from the cloth when the cloth is discharged, effectively reducing the waste of dye liquid.

[0004] Different types of fabrics have different thicknesses at the outlet, and the same type of fabric has different thicknesses at different outlet points. For different types of fabrics, the spacing between the two rollers needs to be adjusted separately; for the same type of fabric, too much thickness will lead to too much resistance during fabric transmission, and too little thickness will lead to insufficient water squeezing of the fabric. In addition, when squeezing the fabric, the fabric needs to pass through two rollers, and the spacing between the two rollers is relatively small, so it is difficult for the fabric to pass through the two rollers. Utility Model Content

[0005] The utility model aims to provide a cloth squeezing and water recovery mechanism for a dye vat, which can adjust the distance between the fixed roller and the movable roller according to the thickness of the cloth output by arranging a fixed roller linked with a motor and a movable roller connected by an elastic component, so as to solve the problem of insufficient water squeezing of the cloth or excessive cloth transmission resistance, thereby facilitating the cloth to pass through the fixed roller and the movable roller.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a cloth squeezing and water recovery mechanism for a dye vat, comprising a water collecting box, a bracket arranged at one side of the water collecting box and used to be connected to the dye vat, a guide ring arranged at both ends of the water collecting box and for the cloth to pass through, a fixed roller rotatably arranged in the middle of the water collecting box, a motor arranged outside the water collecting box and linked with the fixed roller, a movable roller arranged in the middle of the water collecting box and located above the fixed roller, a reflux component implemented at the bottom of the water collecting box and realizing the delivery of dye solution to the dye vat, support track arms extending in the vertical direction are arranged on both sides of the water collecting box, and the support track arms extend along the vertical direction. A lifting seat is arranged on the rail arm, and a connecting plate is arranged on the lifting seat. A base is arranged on the upper end of the support rail arm, and a guide shaft passing through the base in the vertical direction is arranged on the lifting seat. A compression spring is sleeved on the guide shaft and its two ends are pressed against between the base and the lifting seat, and an adjusting knob is threadedly connected to the upper end of the guide shaft for pressing against the upper surface of the base and limiting the lowest position of the lifting seat; the upper end of the support rail arm is rotatably connected to the inner side of the water collecting tank, and a fixing component for limiting or unlocking the support rail arm in a vertical state is arranged in the water collecting tank; the two ends of the fixed roller are rotatably connected between the lower ends of the two connecting plates.

[0007] By adopting the above technical scheme, when it is necessary to make the cloth pass through the fixed roller and the movable pressure roller, the vertical state of the support track arm is released by the fixed component, so that the upper end of the support track arm is in a rotatable state. At this time, by pushing the movable roller, the rotation axis of the upper end of the support track arm can be rotated, so that the distance between the fixed roller and the movable roller is increased, thereby facilitating the cloth to pass out; at the same time, when the cloth is squeezed, the lifting seat, the guide shaft, the compression spring, and the adjustment knob are set, so that when the cloth thickness is large, the movable pressure roller can move upward after being forced, which can solve the problem of excessive cloth transmission resistance. The compression spring and the movable roller themselves can ensure that the cloth is pressed tightly, which can solve the problem of insufficient cloth squeezing.

[0008] The utility model is further configured as follows: the fixing assembly includes a limit block arranged on the inner side of the water collecting tank and below the supporting rail arm, and a limit sleeve arranged on the side of the connecting plate and matched with the limit block; the limit block and the limit sleeve are relatively extended and retracted following the lifting and lowering of the connecting plate; when the movable roller moves downward and abuts against the fixed roller, the limit sleeve is disengaged from the limit block and does not interfere with the rotation of the supporting rail arm.

[0009] By adopting the above technical solution, when the movable roller and the fixed roller are in use, a certain distance needs to be ensured between the movable roller and the fixed roller for the cloth to pass through. At this time, the fixed component is arranged on the inner side of the water collecting tank and the side of the connecting plate, and when the movable roller moves downward and hits the fixed roller, the limit sleeve is disengaged from the limit block and does not interfere with the rotation of the support track arm, so that the support track arm can rotate, and when it is unlocked, it is only necessary to loosen the adjusting knob, which is very convenient for adjustment.

[0010] The utility model is further configured as follows: the lower end surface of the limit block is an arc surface that protrudes downward and the center of the circle is on the rotation axis of the support rail arm, and the upper end surface of the limit sleeve is an arc surface that is concave downward and the center of the circle is on the rotation axis of the support rail arm.

[0011] By adopting the above technical solution, since the limit sleeve rotates with the support rail arm, the lower end face of the alignment block is a downwardly protruding arc surface with the center of the circle located on the rotation axis of the support rail arm, and the upper end face of the limit sleeve is a downwardly concave arc surface with the center of the circle located on the rotation axis of the support rail arm. At this time, the height of the limit sleeve and the limit block when they cooperate with each other can be reduced, which facilitates control within the minimum distance between the movable roller and the fixed roller.

[0012] The utility model is further configured as follows: a drain port is provided at the bottom of the water collecting tank, and the reflux assembly includes a reflux pipe which is telescopically arranged at the bottom of the water collecting tank and is used to enter the dye vat after being extended, a hose which is arranged between the drain port and the reflux pipe, and a limiter which is arranged between the bottom of the water collecting tank and the reflux pipe and limits the telescopic travel of the reflux pipe.

[0013] By adopting the above technical solution, a reflux pipe is provided which can be extended and enter the dye vat, so that the dye liquid in the water collecting box can flow back into the dye vat, and the extension and retraction stroke of the reflux pipe can be limited by the setting of the limiter.

[0014] The utility model is further configured as follows: a guide seat for the return pipe to pass through is provided at the bottom of the water collecting tank, and the limiting member includes two limiting rings installed on the periphery of the return pipe and located on both sides of the guide seat, and limiting screws for fixing the limiting rings on the periphery of the return pipe; when one of the limiting rings and the guide seat are in conflict with each other, the return pipe is in a retracted state; when the other limiting ring and the guide seat are in conflict with each other, the return pipe is in a fully extended state.

[0015] By adopting the above technical solution, when one of the limit rings and the guide seat conflicts with each other, the return pipe is in a retracted state, and when the other limit ring and the guide seat conflicts with each other, the return pipe is in a fully extended state, thereby achieving limiting of the extension and retraction of the return pipe.

[0016] The utility model is further configured as follows: annular magnets are embedded at both ends of the guide seat, the limiting ring is made of iron, and the annular magnet of the guide seat and the limiting ring are magnetically adsorbed after they collide with each other.

[0017] By adopting the above technical solution, when the return pipe is extended and retracted to two extreme states, the annular magnet of the guide seat and the limit ring are magnetically adsorbed after contacting each other, thereby preventing the return pipe from loosening.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Embodiment: A dye vat cloth squeezing water recovery mechanism, such as Figure 1 and Figure 3 As shown, it includes a water collecting tank 1, a bracket 2 arranged at one side of the water collecting tank 1 and used to connect to the dyeing tank, a guide ring 3 arranged at both ends of the water collecting tank 1 and for the cloth to pass through, a fixed roller 4 rotatably arranged in the middle of the water collecting tank 1, a motor 5 arranged on the outside of the water collecting tank 1 and linked to the fixed roller 4, a movable roller 6 arranged in the middle of the water collecting tank 1 and located above the fixed roller 4, and a reflux component implemented at the bottom of the water collecting tank 1 and realizing the transportation of dye solution to the dyeing tank.

[0024] like Figure 1 and Figure 2As shown, support rail arms 11 extending along the vertical direction are arranged on both sides of the water collecting tank 1, a lifting seat 12 is arranged on the support rail arms 11, and a connecting plate 13 is arranged on the lifting seat 12. A base 14 is arranged on the upper end of the support rail arm 11, and a guide shaft 15 (the upper end has a thread but is not shown in the figure) passing through the base 14 along the vertical direction is arranged on the lifting seat 12. A compression spring 16 with both ends pressed between the base 14 and the lifting seat 12 is sleeved on the guide shaft 15, and an adjusting knob 17 for pressing against the upper surface of the base 14 and limiting the lowest position of the lifting seat 12 is threadedly connected at the upper end of the guide shaft 15; the upper end of the support rail arm 11 is rotatably connected to the inner side of the water collecting tank 1, and a fixing component 18 for limiting or unlocking the support rail arm 11 in a vertical state is arranged in the water collecting tank 1; the two ends of the fixed roller 4 are rotatably connected between the lower ends of the two connecting plates 13.

[0025] like Figure 1 and Figure 2 As shown, the fixing assembly 18 includes a limit block 181 arranged inside the water collecting tank 1 and below the support rail arm 11, and a limit sleeve 182 arranged on the side of the connecting plate 13 and matched with the limit block 181. The limit block 181 and the limit sleeve 182 are relatively extended and retracted following the lifting and lowering of the connecting plate 13. When the movable roller 6 moves downward and contacts the fixed roller 4, the limit sleeve 182 is separated from the limit block 181 and does not interfere with the rotation of the support rail arm 11. In addition, the lower end surface of the limit block 181 is an arc surface that protrudes downward and the center of the circle is on the rotation axis of the support rail arm 11, and the upper end surface of the limit sleeve 182 is an arc surface that is concave downward and the center of the circle is on the rotation axis of the support rail arm 11.

[0026] like Figure 1 and Figure 3 As shown, a drain port 19 is provided at the bottom of the water collecting tank 1, and the reflux assembly includes a reflux pipe 71 which is telescopically provided at the bottom of the water collecting tank 1 and is used to enter the dye vat after being extended, a hose 72 which is provided between the drain port 19 and the reflux pipe 71, and a stopper 73 which is provided between the bottom of the water collecting tank 1 and the reflux pipe 71 and limits the telescopic travel of the reflux pipe 71. A guide seat 110 for the reflux pipe 71 to pass through is provided at the bottom of the water collecting tank 1, and the stopper 73 includes two stopper rings 731 which are installed on the periphery of the reflux pipe 71 and are located on both sides of the guide seat 110, and a stopper screw 732 which is used to fix the stopper ring 731 on the periphery of the reflux pipe 71. When one of the stopper rings 731 conflicts with the guide seat 110, the reflux pipe 71 is in a retracted state, and when the other stopper ring 731 conflicts with the guide seat 110, the reflux pipe 71 is in a fully extended state. Meanwhile, annular magnets 111 are embedded at both ends of the guide seat 110 , and the limiting ring 731 is made of iron. The annular magnet 111 of the guide seat 110 and the limiting ring 731 are magnetically adsorbed after contacting each other.

[0027] Implementation effect: when it is necessary to make the cloth pass through the fixed roller 4 and the movable pressure roller, the vertical state of the support track arm 11 is released by the fixed component 18, so that the upper end of the support track arm 11 is in a rotatable state. At this time, by pushing the movable roller 6, the rotation axis of the upper end of the support track arm 11 can be rotated, so that the distance between the fixed roller 4 and the movable roller 6 is increased, thereby facilitating the cloth to pass out; at the same time, when the cloth is squeezed, through the setting of the lifting seat 12, the guide shaft 15, the compression spring 16, and the adjustment knob 17, when encountering a thicker cloth, the movable pressure roller can move upward after being forced, which can solve the problem of excessive cloth transmission resistance. The compression spring 16 and the movable roller 6 themselves can ensure that the cloth is pressed tightly, which can solve the problem of insufficient cloth squeezing.

[0028] When the movable roller 6 and the fixed roller 4 are in use, a certain distance between the movable roller 6 and the fixed roller 4 is required to allow the cloth to pass through. At this time, the fixed assembly 18 is set on the inner side of the water collecting box 1 and the side of the connecting plate 13, and when the movable roller 6 moves downward and contacts the fixed roller 4, the limiting sleeve 182 is separated from the limiting block 181 and does not interfere with the rotation of the support rail arm 11, so that the support rail arm 11 can rotate, and when unlocking, it is only necessary to loosen the adjustment knob 17, which is very convenient for adjustment. Because the limiting sleeve 182 rotates with the support rail arm 11, the lower end face of the alignment block is a curved surface that protrudes downward and the center of the circle is on the rotation axis of the support rail arm 11, and the upper end face of the limiting sleeve 182 is a curved surface that is concave downward and the center of the circle is on the rotation axis of the support rail arm 11. At this time, the height of the limiting sleeve 182 and the limiting block 181 when they cooperate with each other can be reduced, so that it is convenient to control within the minimum distance between the movable roller 6 and the fixed roller 4.

[0029] By providing a return pipe 71 that can be extended and then enter the dye vat, the dye liquid in the water collecting box 1 can flow back into the dye vat, and the setting of the limiter 73 can limit the telescopic stroke of the return pipe 71. When one of the limit rings 731 and the guide seat 110 conflicts with each other, the return pipe 71 is in a storage state, and when the other limit ring 731 and the guide seat 110 conflict with each other, the return pipe 71 is in a complete extension state, thereby limiting the telescopic extension of the return pipe 71. When the return pipe 71 is extended to two extreme states, the annular magnet 111 of the guide seat 110 and the limit ring 731 conflict with each other and are magnetically adsorbed, thereby preventing the return pipe 71 from loosening.

[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
