Description

Technical Field

[0001] The present invention relates to the technical field of woven fabric processing devices, and particularly to a pretreatment device for all-cotton woven fabrics. Background Art

[0002] Sizing is an important step in the pretreatment process of all-cotton woven fabrics. Sizing is to enhance the strength and wear resistance of yarns and prevent the yarns from breaking during the weaving process. The sizing equipment includes a sizing machine, which immerses the yarns in a starch or synthetic resin sizing solution and then dries them to form a protective film.

[0003] When sizing the yarns, in the prior art, sizing is carried out through a sizing vat, so that the sizing solution at the bottom of the sizing vat cannot be used, which is prone to precipitation, resulting in waste of the sizing solution. In addition, during the sizing process, it is particularly easy to occur that the yarn tension is uneven, resulting in yarn relaxation, and the yarn tension cannot be adjusted during the sizing process, which has an irreversible impact on the sizing quality of the yarns. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a pretreatment device for all-cotton woven fabrics.

[0005] The above technical object of the present invention is achieved by the following technical solutions: A pretreatment device for all-cotton woven fabrics includes a base, a sizing vat fixed on the top of the base, a pay-off roll arranged on one side of the sizing vat, and a take-up roll arranged on the other side of the sizing vat. A plurality of sizing rolls distributed in an S shape are rotatably installed between the side walls on both sides of the sizing vat. The sizing rolls are located close to the inner bottom wall of the sizing vat. The axial direction of the sizing rolls is parallel to the axial directions of the pay-off roll and the take-up roll. A circulation assembly is arranged on the base for circulating the sizing solution in the sizing vat to prevent precipitation. Two symmetrically distributed tension rolls for keeping the yarns taut are arranged between the side walls on both sides of the sizing vat. An adjusting mechanism for adjusting the distance between the two tension rolls is arranged on the sizing vat.

[0006] By adopting the above technical solutions, the setting of the circulation assembly enables the sizing solution in the sizing vat to circulate, reducing the probability of affecting the sizing effect of the yarns due to precipitation of the sizing solution. The distance between the two tension rolls can be adjusted through the adjusting mechanism, so that the distance between the two tension rolls can be adjusted to the degree of tightening the yarns in time, which is beneficial to ensuring the sizing quality of the yarns.

[0007] Furthermore, the adjustment mechanism includes a mounting assembly, a transmission assembly and a drive assembly, the mounting assembly includes a transverse plate fixed on the outer wall of the slurry tank body, a threaded rod that is arranged on the transverse plate and is rotatably connected, a transverse rod that is sleeved on the threaded rod and has a clearance fit, and a connecting block that is sleeved on the threaded rod and is threadedly connected, both ends of the transverse rod are provided with mounting holes, the connecting block is provided with an adjustable assembly for connecting with the transverse rod, and the drive assembly is used to drive the threaded rod to rotate; the transmission assembly is provided with two and respectively arranged at both ends of the transverse rod, respectively used to control the two tension rollers to move closer or farther away from each other, and each group of the transmission assembly The components include a spring fixed to one end of the threaded rod close to the mounting hole, a connecting rod fixed to one end of the spring away from the threaded rod, a roller shaft rotatably mounted on one end of the connecting rod away from the spring, a slider fixed to the end of the tension roller, and a control block fixed to the side of the slider away from the tension roller. The side walls on both sides of the slurry tank body are provided with transverse sliding grooves that slidably cooperate with the slider. The roller shafts are provided with two and are symmetrically arranged. The two control blocks are provided with V-shaped grooves on one side close to each other. The two control blocks are provided with a guide groove connected to the V-shaped groove on one side close to each other. The guide grooves are slidably cooperated with the connecting rod and the two roller shafts.

[0008] By adopting the above technical solution, when it is necessary to adjust the distance between the two tension rollers, the staff only needs to drive the threaded rod to rotate through the driving component. Due to the clearance fit between the threaded rod and the cross bar, the threaded rod is threadedly connected to the connecting block, and the adjustable component connects the connecting block to the cross bar, so that the connecting block and the cross bar can be raised and lowered during the rotation of the threaded rod. Since the roller shaft at the end of the connecting rod slides with the guide groove on the control block, when the roller shaft abuts against the inclined section of the guide groove (the inclined portion corresponding to the V-shaped groove), the connecting rod pulls the roller shafts on both sides closer to or away from each other under the elastic force of the spring, so that the control blocks on both sides are subjected to the interference effect and the two tension rollers are moved closer to or away from each other, so as to tension the yarn and ensure the yarn sizing effect.

[0009] Furthermore, the adjustable component includes a connecting shaft that is penetrated and fixed on the connecting block, a Z-shaped plate body fixed to the end of the connecting shaft, and a torsion spring sleeved on the connecting shaft, the Z-shaped plate bodies are provided with two and are symmetrically arranged, and the sides of the two Z-shaped plates close to each other are respectively flush with the side walls on both sides of the connecting block and the side walls on both sides of the cross bar, one end of the torsion spring is fixed to the side wall on one side of the connecting block, and the other end of the torsion spring is fixed to one of the Z-shaped plate bodies, and a pin that is gap-matched with the Z-shaped plate body is penetrated on the Z-shaped plate body, and when the top of the pin connecting the two Z-shaped plates is pressed against the bottom of the cross bar, the torsion spring is in a tensioned state.

[0010] By adopting the above technical solution, after one end of the Z-shaped plate body far from the connecting shaft rotates to the bottom of the cross bar, the two Z-shaped plate bodies can be connected by using a bolt, so that the connecting block and the cross bar can be connected. At this time, when the driving component drives the threaded rod to rotate, the two tension rollers can move closer to or away from each other.

[0011] Further, a limiting block is fixed on the side wall of one side of the connecting block, and the limiting block is used to limit the Z-shaped plate body after the Z-shaped plate body loses its connection effect on the cross bar.

[0012] By adopting the above technical solution, the limiting block plays a good limiting role on the Z-shaped plate body after the bolt is pulled out.

[0013] Further, the driving component includes a motor fixed on the outer wall of the slurry tank, a worm fixed to the output end of the motor, and a worm gear fixed on the threaded rod and meshed with the worm.

[0014] By adopting the above technical solution, after the motor works, it drives the worm to rotate, so that the worm gear meshed with the worm and the threaded rod fixed to the worm gear both rotate.

[0015] Further, the circulating component includes a circulating tank fixed on the top of the base, a feeding pump fixed on the top of the base, and a circulating pump fixed on the top of the base. The feeding end of the feeding pump and the discharging end of the circulating pump are both communicated with the slurry tank. The discharging end of the feeding pump and the feeding end of the circulating pump are both communicated with the circulating tank. A rotating rod rotatably connected to the circulating tank is arranged through the bottom of the circulating tank. The rotating rod is sealed with the bottom of the circulating tank. The rotating rod penetrates through the base and has a clearance fit. Stirring blades are fixed on the side wall of the rotating rod. The rotating rod and the threaded rod are connected through a linkage component.

[0016] By adopting the above technical solution, the feeding pump and the circulating pump cooperate to make the slurry in the slurry tank circulate between the circulating tank and the slurry tank. After the motor works, it drives the rotating rod to rotate through the linkage component, so that the rotating rod and the stirring blades rotate, so as to stir the slurry in the circulating tank to make the slurry circulated into the slurry tank have a good sizing effect.

[0017] Further, the linkage component includes a main synchronous pulley fixed at the lower end of the threaded rod, a slave synchronous pulley fixed at the lower end of the rotating rod, and a synchronous belt meshed with both the slave synchronous pulley and the main synchronous pulley.

[0018] By adopting the above technical solution, when the distance between the two tension rollers is adjusted to the yarn tension, the distance between the two tension rollers does not need to be adjusted. The staff only needs to pull out the pin so that the Z-shaped plate body abuts against the bottom of the limit block under the action of the torsion spring. At this time, the Z-shaped plate body no longer connects the connecting block to the cross bar. If the threaded rod rotates, the connecting block rotates synchronously with the threaded rod, and the cross bar does not move up and down under the rotation of the threaded rod. Therefore, the distance between the two tension rollers remains constant. After the motor works and the worm, worm wheel and threaded rod rotate, under the action of the synchronous belt, the slave synchronous wheel rotates synchronously with the main synchronous wheel, so that the rotating rod fixed to the slave synchronous wheel and the stirring blade fixed to the rotating rod both rotate, thereby stirring the slurry in the circulation box.

[0019] Furthermore, the cross sections of the transverse slide groove and the sliding block are both rectangular.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. In the present application, the setting of the circulation component enables the slurry in the slurry tank to circulate, reducing the probability of affecting the sizing effect of the yarn due to slurry precipitation. The distance between the two tension rollers can be adjusted by the adjustment mechanism, so that the distance between the two tension rollers can be adjusted in time to the degree of tightening the yarn, which is conducive to ensuring the sizing quality of the yarn;

[0022] 2. In the present application, when it is necessary to adjust the spacing between the two tension rollers, the staff only needs to drive the threaded rod to rotate through the driving assembly. Due to the clearance fit between the threaded rod and the cross bar, the threaded rod is threadedly connected to the connecting block, and the adjustable assembly connects the connecting block to the cross bar, so that the connecting block and the cross bar can be raised and lowered during the rotation of the threaded rod. Since the roller shaft at the end of the connecting rod slides with the guide groove on the control block, when the roller shaft abuts against the inclined section of the guide groove (the inclined portion corresponding to the V-shaped groove), the connecting rod pulls the roller shafts on both sides closer to or away from each other under the elastic force of the spring, so that the control blocks on both sides are subjected to the interference effect and the two tension rollers are brought closer to or away from each other, so as to tension the yarn and ensure the yarn sizing effect.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] As Figure 1-7 shown, an embodiment of the present application discloses a pretreatment device for all-cotton woven fabrics, including a base 1, a slurry tank 2 fixed on the top of the base 1, an unwinding roller 3 arranged on one side of the slurry tank 2, and a winding roller 4 arranged on the other side of the slurry tank 2. A plurality of sizing rollers 5 distributed in an S shape are rotatably installed between the side walls on both sides of the slurry tank 2. The sizing rollers 5 are located close to the inner bottom wall of the slurry tank 2. The axial direction of the sizing rollers 5 is parallel to the axial directions of both the unwinding roller 3 and the winding roller 4. A circulation component 6 is arranged on the base 1 for circulating the slurry in the slurry tank 2 to prevent precipitation. Two symmetrically distributed tension rollers 7 for keeping the yarn taut are arranged between the side walls on both sides of the slurry tank 2. An adjusting mechanism 8 for adjusting the distance between the two tension rollers 7 is arranged on the slurry tank 2.

[0033] The arrangement of the circulation component 6 allows the slurry in the slurry tank 2 to circulate, reducing the probability of affecting the sizing effect of the yarn due to slurry precipitation. The spacing between the two tension rollers 7 can be adjusted by the adjustment mechanism 8, so that the spacing between the two tension rollers 7 can be adjusted in time to the degree of tightening the yarn, which is conducive to ensuring the sizing quality of the yarn.

[0034] The adjusting mechanism 8 includes a mounting assembly 81, a transmission assembly 82 and a driving assembly 83. The mounting assembly 81 includes a transverse plate 811 fixed on the outer wall of the slurry tank body 2, a threaded rod 812 that is arranged on the transverse plate 811 and is rotatably connected, a transverse rod 813 that is sleeved on the threaded rod 812 and has a clearance fit, and a connecting block 814 that is sleeved on the threaded rod 812 and is threadedly connected. Both ends of the transverse rod 813 are provided with mounting holes 8131, and the connecting block 814 is provided with an adjustable assembly 9 for connecting with the transverse rod 813. The driving assembly 83 is used to drive the threaded rod 812 to rotate; the transmission assembly 82 is provided with two and is respectively arranged at both ends of the transverse rod 813, respectively used to control the two tension rollers 7 to move closer or farther from each other, and each group of transmission assemblies 82 includes a fixed end of the threaded rod 812 that is close to the mounting hole 8131. A spring 821 is fixed, a connecting rod 822 is fixed to the end of the spring 821 away from the threaded rod 812, a roller shaft 823 is rotatably installed on the end of the connecting rod 822 away from the spring 821, a slider 824 is fixed to the end of the tension roller 7, and a control block 825 is fixed to the side of the slider 824 away from the tension roller 7, and the side walls on both sides of the slurry tank body 2 are provided with transverse sliding grooves 21 (the cross-sections of the transverse sliding grooves 21 and the slider 824 are both rectangular) that are slidably matched with the slider 824, the roller shaft 823 is provided with two and is symmetrically arranged, a V-shaped groove 8251 is provided on the side where the two control blocks 825 are close to each other, and a guide groove 8252 connected to the V-shaped groove 8251 is provided on the side where the two control blocks 825 are close to each other, and the guide groove 8252 is slidably matched with the connecting rod 822 and the two roller shafts 823.

[0035] When the spacing between the two tension rollers 7 needs to be adjusted, the staff only needs to drive the threaded rod 812 to rotate through the driving component 83. Due to the clearance fit between the threaded rod 812 and the cross bar 813, the threaded rod 812 is threadedly connected to the connecting block 814, and the adjustable component 9 connects the connecting block 814 to the cross bar 813, so that the connecting block 814 and the cross bar 813 can be raised and lowered during the rotation of the threaded rod 812. Since the roller shaft 823 at the end of the connecting rod 822 slides with the guide groove 8252 on the control block 825, when the roller shaft 823 abuts against the inclined section of the guide groove 8252 (the inclined portion corresponding to the V-shaped groove 8251), the connecting rod 822 pulls the roller shafts 823 on both sides closer to or away from each other under the elastic force of the spring 821, so that the control blocks 825 on both sides are subjected to the interference effect and the two tension rollers 7 are brought closer to or away from each other to tension the yarn and ensure the yarn sizing effect.

[0036] The adjustable component 9 includes a connecting shaft 91 that penetrates and is fixed on the connecting block 814, a Z-shaped plate body 92 fixed to the end of the connecting shaft 91, and a torsion spring 93 sleeved on the connecting shaft 91. There are two Z-shaped plate bodies 92 which are symmetrically arranged. The sides of the two Z-shaped plate bodies 92 close to each other are flush with the side walls on both sides of the connecting block 814 and the side walls on both sides of the cross bar 813. One end of the torsion spring 93 is fixed to the side wall of one side of the connecting block 814, and the other end of the torsion spring 93 is fixed to one of the Z-shaped plate bodies 92. A pin 10 that is in clearance fit with the Z-shaped plate body 92 penetrates through the Z-shaped plate body 92. When the top of the pin 10 connecting the two Z-shaped plate bodies 92 abuts against the bottom of the cross bar 813, the torsion spring 93 is in a taut state.

[0037] A limiting block 8141 is fixed on the side wall of one side of the connecting block 814. The limiting block 8141 is used to limit the Z-shaped plate body 92 after the Z-shaped plate body 92 loses its connection function to the cross bar 813. The limiting block 8141 plays a good limiting role for the Z-shaped plate body 92 after the pin 10 is pulled out.

[0038] The driving component 83 includes a motor 831 fixed on the outer wall of the slurry tank body 2, a worm 832 fixed to the output end of the motor 831, and a worm gear 833 fixedly sleeved on the threaded rod 812 and meshing with the worm 832. After the motor 831 works, it drives the worm 832 to rotate, so that the worm gear 833 meshing with the worm 832 and the threaded rod 812 fixed to the worm gear 833 both rotate.

[0039] The circulation component 6 includes a circulation tank 61 fixed on the top of the base 1, a feed pump 62 fixed on the top of the base 1, and a circulation pump 63 fixed on the top of the base 1. The feed end of the feed pump 62 and the discharge end of the circulation pump 63 are both communicated with the slurry tank body 2, and the discharge end of the feed pump 62 and the feed end of the circulation pump 63 are both communicated with the circulation tank 61. A rotating rod 611 that is rotatably connected to the circulation tank 61 penetrates through the bottom of the circulation tank 61. The rotating rod 611 is sealed with the bottom of the circulation tank 61. The rotating rod 611 penetrates through the base 1 and is in clearance fit. A stirring blade 6111 is fixed on the side wall of the rotating rod 611. The rotating rod 611 and the threaded rod 812 are connected by a linkage component 11. The feed pump 62 and the circulation pump 63 cooperate with each other, so that the slurry in the slurry tank body 2 circulates between the circulation tank 61 and the slurry tank body 2. After the motor 831 works, it drives the rotating rod 611 to rotate through the linkage component 11, so that the rotating rod 611 and the stirring blade 6111 rotate, in order to stir the slurry in the circulation tank 61, so that the slurry circulated into the slurry tank body 2 has a good sizing effect.

[0040] The linkage component 11 includes a main synchronous pulley 111 fixed to the lower end of the threaded rod 812, a slave synchronous pulley 112 fixed to the lower end of the rotating rod 611, and a synchronous belt 113 that meshes with both the slave synchronous pulley 112 and the main synchronous pulley 111.

[0041] When the distance between the two tension rollers 7 is adjusted until the yarn is tensioned, the distance between the two tension rollers 7 does not need to be adjusted anymore. The staff only needs to pull out the pin 10, so that the Z-shaped plate body 92 abuts against the bottom of the limit block 8141 under the action of the torsion spring 93. At this time, the Z-shaped plate body 92 no longer connects the connecting block 814 to the cross bar 813. If the threaded rod 812 rotates, the connecting block 814 rotates synchronously with the threaded rod 812, and the cross bar 813 will not move up and down under the rotation of the threaded rod 812. Therefore, the distance between the two tension rollers 7 remains constant. After the motor 831 works and makes the worm 832, the worm wheel 833 and the threaded rod 812 rotate, under the action of the synchronous belt 113, the slave synchronous pulley 112 rotates synchronously with the main synchronous pulley 111, so that the rotating rod 611 fixed to the slave synchronous pulley 112 and the stirring blade 6111 fixed to the rotating rod 611 both rotate, thereby stirring the slurry in the circulation tank 61.

[0042] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
