Description

Technical Field

[0001] The utility model relates to a desizing and washing machine, in particular to a desizing and washing machine for denim that eliminates curling. Background Technique

[0002] Denim desizing and washing is an important technological process aimed at removing the sizing and floating color on denim to improve wearing comfort and appearance; the purpose of desizing is to remove the sizing on the clothing to facilitate subsequent processing. During the manufacturing process of denim, in order to achieve specific effects; during the dyeing process of denim, due to the characteristics of dyes such as indigo, it is impossible to achieve a 100% dyeing rate, so a large amount of floating color will be left. If these floating colors are not treated, they will affect the appearance and quality of denim. Through the washing process, these floating colors can be effectively removed, making the color of denim more uniform and bright. Common desizing and washing equipment includes singeing and desizing combined machines, cold pad batch machines, etc.

[0003] The common singeing and desizing combined machine on the market is a machine with main functions such as singeing, desizing, and pre-shrinking, which can orderly process denim as required; its desizing and washing process is usually carried out during the fabric running process and is completed by soaking in the desizing and washing liquid once or multiple times. The way to eliminate curling is completed in the pre-shrinking process (by applying tension to the denim to make it more taut).

[0004] However, since denim becomes soft during the desizing and washing process, and its softness is related to factors such as soaking time and the composition of the desizing and washing liquid; the originally taut denim becomes loose, which in turn increases the occurrence of curling and wrinkling of denim. At this time, it is no longer possible to make the denim taut again by increasing the tension (if the tension is large, the denim is easily damaged, and if the tension is small, the denim cannot be made taut), and the curling of denim will affect the beauty, wearing comfort, service life, and increase production costs.

[0037] Next, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] Please refer to Figures 1 to 6 , as an embodiment of the present invention, the denim desizing and washing machine for eliminating curling includes a chassis 1 and a desizing and washing tank 101 fixedly installed in the chassis 1;

[0039] An inlet cloth roller 3 and an outlet cloth roller 4 are rotatably installed on the desizing and washing tank 101. A cloth running mechanism is connected to the outlet cloth roller 4, and the cloth running mechanism can drive the outlet cloth roller 4 to rotate;

[0040] A spraying mechanism cooperating with the cloth running mechanism is arranged in the desizing and washing tank 101. A plurality of groups of nozzles 9 are connected to the spraying mechanism. When the cloth running mechanism operates, the spraying mechanism can spray desizing and washing liquid on the denim through the nozzles 9;

[0041] A cloth smoothing mechanism for smoothing the denim is further arranged in the desizing and washing tank 101.

[0042] In this embodiment, the chassis 1 is firmly installed, and then desizing and washing liquid is injected into the desizing and washing tank 101 until the liquid level covers the first cloth guiding roller 5 and the second cloth guiding roller 6. The denim raw material to be desized and washed is connected to the inlet cloth roller 3, the first cloth guiding roller 5, the second cloth guiding roller 6 and the outlet cloth roller 4.

[0043] Start the cloth running mechanism and the spraying mechanism. When the cloth running mechanism operates, it will drive the outlet cloth roller 4 to rotate, thereby pulling the denim through the desizing and washing liquid. At the same time, the spraying mechanism will spray the desizing and washing liquid towards the edges of the advancing denim through the nozzles 9. The impact force generated by the desizing and washing liquid sprayed by the nozzles 9 will synchronously impact the edges of the denim from the upper and lower directions of the denim to reduce the probability of the denim curling.

[0044] The denim soaked in the desizing and washing liquid will pass through the cloth smoothing mechanism. During this process, the cloth smoothing mechanism will squeeze the denim from both sides of the denim to make the denim more flat and squeeze out the excess desizing and washing liquid to prevent damage to the denim due to excessive desizing and washing.

[0045] By controlling the rotation speed of the cloth delivery mechanism to drive the rotation of the cloth outlet roller 4, the degree of desizing and washing of denim can be controlled, so that the quality of denim after the desizing and washing process is higher; the spraying mechanism sprays the edge of the denim through the nozzle 9, which can effectively reduce the probability of curling during desizing and washing, thereby improving the quality of the finished product; the cloth smoothing mechanism can filter out the excess desizing and washing liquid on the denim to prevent excessive desizing and washing, and can smooth the denim, effectively improving the quality of the denim.

[0046] As a further solution of the present utility model, a first cloth guiding roller 5 and a second cloth guiding roller 6 are rotatably installed on the desizing and washing tank 101. Belt wheels 11 are fixedly installed on the first cloth guiding roller 5, the second cloth guiding roller 6, the cloth inlet roller 3 and the cloth outlet roller 4, and the belt wheels 11 are connected by a belt 12.

[0047] The cloth delivery mechanism includes a motor 2 fixedly installed on the desizing and washing tank 101, and the output end of the motor 2 is fixedly connected to the cloth outlet roller 4.

[0048] In this embodiment, the denim is connected above the cloth inlet roller 3, below the first cloth guiding roller 5 and the second cloth guiding roller 6, and above the cloth outlet roller 4. The cloth outlet roller 4 and the cloth inlet roller 3 are at the same horizontal height, the first cloth guiding roller 5 and the second cloth guiding roller 6 are at the same horizontal height, and the cloth outlet roller 4 is higher than the second cloth guiding roller 6.

[0049] When the motor 2 works, it can drive the cloth outlet roller 4 to rotate, thereby driving the second cloth guiding roller 6, the first cloth guiding roller 5 and the cloth inlet roller 3 to rotate through the belt 12, so as to pull the denim from the direction of the cloth inlet roller 3 to the direction of the cloth outlet roller 4; the first cloth guiding roller 5 and the second cloth guiding roller 6 are located below the liquid level of the desizing and washing liquid, so during the process of the denim from the direction of the cloth inlet roller 3 to the direction of the cloth outlet roller 4, it will be immersed in the desizing and washing liquid to complete desizing and washing.

[0050] Since the cloth delivery mechanism pulls the denim forward, compared with pushing the denim forward, it can effectively avoid wrinkles and curling during the cloth walking process, and by controlling the rotation speed of the cloth delivery mechanism to drive the rotation of the cloth outlet roller 4, the degree of desizing and washing of the denim can be controlled, so that the quality of the denim after the desizing and washing process is higher.

[0051] As a further solution of the present utility model, the spraying mechanism includes a water pump 8 fixedly installed on the chassis 1. The water inlet of the water pump 8 is communicated with the desizing and washing tank 101, and a water outlet pipe 801 communicated with the nozzle 9 is fixedly connected to the water outlet end of the water pump 8.

[0052] In this embodiment, when the motor 2 starts, the water pump 8 starts synchronously. The water pump 8 will pump out the desizing and washing liquid in the desizing and washing tank 101 and discharge it from the nozzle 9 through the water outlet pipe 801. The spraying mechanism will spray the desizing and washing liquid towards the edges of the moving denim through the nozzle 9. The impact force generated by the desizing and washing liquid sprayed by the nozzle 9 will impact the edges of the denim synchronously from the upper and lower directions of the denim, so as to reduce the probability of the denim curling.

[0053] As a further solution of the present utility model, multiple groups of the nozzles 9 are symmetrically arranged on the upper and lower sides of the tangent direction at the upper end between the first fabric guiding roller 5 and the second fabric guiding roller 6, and the nozzles 9 are inclined.

[0054] In this embodiment, the nozzle 9 is bent, the water outlet of the nozzle 9 is aligned with the edge position of the denim, and the nozzle 9 is inclined, and the inclination direction is away from the fabric running direction of the denim.

[0055] Since the spraying mechanism operates when the fabric running mechanism operates, setting the nozzle 9 inclined can make the force on the denim more balanced, which is beneficial to the stable running of the denim and prevents the impact force generated by the spraying mechanism from causing the denim to be misaligned.

[0056] Impact the edges of the denim synchronously from the upper and lower directions of the denim, which can effectively reduce the probability of curling during the fabric running process.

[0057] As a further solution of the present utility model, the fabric straightening mechanism includes sliding grooves 102 fixedly and symmetrically installed on both sides of the desizing and washing tank 101. A fabric straightening plate 10 is slidably installed in the sliding grooves 102, and a spring 103 fixedly connected to the fabric straightening plate 10 is fixedly installed in the sliding grooves 102.

[0058] In this embodiment, the fabric straightening plate 10 can slide in the sliding groove 102. Initially, the spring 103 is in a compressed state, so that the two fabric straightening plates 10 always tend to approach each other, and the denim passes through the middle of the two fabric straightening plates 10. The elastic force of the spring 103 will drive the fabric straightening plate 10 to squeeze the denim to filter out the excess desizing and washing liquid on the denim, preventing damage to the denim due to excessive desizing and washing. And due to the squeezing effect of the fabric straightening plate 10, the denim will be straightened to improve the quality of the finished denim.

[0059] As a further solution of the present utility model, a plurality of fabric straightening rollers 7 rotatably connected to the desizing and washing tank 101 are arranged between the first fabric guiding roller 5 and the second fabric guiding roller 6.

[0060] In this embodiment, the setting of the fabric straightening roller 7 can reduce the suspended distance of the denim in the desizing and washing liquid, thereby reducing the probability of the denim curling and wrinkling, and effectively improving the quality of the finished denim.

[0061] As a further solution of the present utility model, multiple groups of the cloth guiding rollers 7 are distributed on the upper and lower sides of the tangential direction at the upper end between the first cloth guiding roller 5 and the second cloth guiding roller 6.

[0062] In this embodiment, since the jeans may have upward or downward curling, by limiting and guiding the lower sides of the denim, the probability of the denim curling and wrinkling can be further reduced. By controlling the rotation speed of the cloth output roller 4 driven by the cloth feeding mechanism, the degree of desizing and washing of the denim can be controlled, so that the quality of the denim after the desizing and washing process is higher; the spraying mechanism sprays the edges of the denim through the nozzles 9, which can effectively reduce the probability of curling during the desizing and washing process, thereby improving the quality of the finished product; the cloth guiding mechanism can filter out the excess desizing and washing liquid on the denim to prevent excessive desizing and washing, and can smooth the denim, effectively improving the quality of the denim.

[0063] The above embodiments are exemplary rather than restrictive. Therefore, without departing from the spirit or basic characteristics of the present utility model, all technical solutions that can implement the present utility model in other specific forms are included in the present utility model.
