[0002] Denim has the characteristics of moisture permeability, air permeability, skin-friendliness, etc., and is widely used in clothing. In the post-treatment process of existing denim fabrics, it usually goes through three processes: singeing, desizing and washing, and pre-shrinking, and finally obtains denim with a smooth surface, such as the content shown in the patent with the authorization announcement number CN109183316B. However, in the existing post-treatment process of denim, after the denim is singed, the yarn structure on its surface will be adhesively connected to a certain extent, and some relatively dense fluff is also likely to form spherical hard lumps, affecting the washing effect in subsequent equipment. Therefore, a singeing and pre-shrinking combined production line for denim with good washing effect in the post-treatment process is needed. Summary of the Invention

[0003] The purpose of the utility model is to solve the deficiencies of the prior art and provide a singeing and pre-shrinking combined production line for denim.

Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0024] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation.

[0025] Embodiment 1:

[0026] As Figures 1 to 5 shown, a singeing and pre-shrinking combined production line for denim fabric includes a singeing machine 1 for fabric singeing and a pre-shrinking main machine 2 for pre-shrinking; it also includes a fabric feeding rack 3, a first brush box 4, a second brush box 5, a padder - water washing tank assembly 6, a skewing device 7, a dryer 8, and a cooling device 9; wherein the fabric feeding rack 3 is arranged at the head end of the production line, and the first brush box 4 is arranged between the fabric feeding rack 3 and the singeing machine 1; a padder - water washing tank assembly 6 is arranged at the fabric outlet of the singeing machine 1, and the second brush box 5 is arranged between the singeing machine 1 and the padder - water washing tank assembly 6; the padder - water washing tank assembly 6 includes at least one padder - water washing tank, and the padder is arranged on the side close to the singeing machine 1, so that the denim fabric is first immersed and then rolled; a skewing device 7 is arranged at the fabric outlet of the padder - water washing tank assembly 6, and the skewing device 7 is also connected to the dryer 8, and the dryer 8 is arranged between the pre-shrinking main machine 2 and the skewing device 7; the pre-shrinking main machine 2 is also connected to the cooling device 9, and the cooling device 9 is located at the end of the production line. Among them, the fabric feeding rack 3 is used to evenly feed the fabric into the first brush box 4. The fabric passes through the brush rollers in the first brush box 4 to stretch the floss on the fabric surface, facilitating the burning off of the fluff on the fabric surface in the subsequent singeing machine 1 to make the fabric surface smooth; after the fabric is singed, it will be transported to the second brush box 5 to remove some spherical substances sintered on the fabric surface; then it goes through the water washing, padding, and drying processes to wash away the unsized slurry in the denim fabric; finally, through pre-shrinking and cooling treatments, the denim fabric is kept tightened, making it have a certain relaxation elasticity, and also improving the anti-shrinking performance.

[0027] The calender - washing trough assembly 6 includes four groups of calender - washing troughs. Through the combination of multiple groups of calender - washing troughs, the denim is repeatedly washed and squeezed to fully wash away the undyed dyes. The power of the calender in the last group of calender - washing troughs in the calender - washing trough assembly 6 is greater than that of the calenders in the first three groups of calender - washing troughs, so that the denim is fully squeezed when leaving the calender - washing trough assembly 6, and as much moisture as possible inside it is removed.

[0028] Inside the singeing machine 1, there are four side - by - side burners, enabling the two edges and the middle area of the denim to be singed fully and evenly, ensuring its smooth surface.

[0029] Inside the dryer 8, there are three columns of roller groups, and the three columns of rollers are arranged in sequence inside the dryer 8. The rollers in each column of roller groups are arranged in a wavy curve in the vertical direction, so that the denim fabric passes through a longer movement path inside the high - temperature drying dryer 8, and is fully dried.

[0030] Between the dryer 8 and the cooling device 9, there is also a transport frame 10 for facilitating the transmission of the fabric. The pre - shrinking main machine 2 is correspondingly arranged with the transport frame 10, and the pre - shrinking main machine 2 is a rubber blanket pre - shrinking main machine. There are rollers on the transport frame 10 for facilitating the transmission of the fabric. The denim fabric is transported to the pre - shrinking main machine 2 through the rollers on the transport frame 10. Because the overall height of the dryer 8 is relatively high, the movement path of the denim fabric inside it is long, while the volume of the pre - shrinking main machine 2 is small. Therefore, there is a certain height difference between the two. In order to prevent the fabric from curling, wrinkling, etc., and keep the fabric in a taut state, the transport frame 10 is set up, and together with the rollers on it, the denim fabric is tensioned.

[0031] During the implementation process, by setting a second singeing machine 1 between the singeing machine 1 and the calender - washing trough assembly 6, the removal of the spherical objects on the surface of the fabric after the singeing treatment is realized, avoiding their influence on the effect of subsequent processes; by setting multiple groups of calender - washing troughs, the full desizing and washing of the fabric are realized; by setting a transport frame 10 between the cooling device 9 and the dryer 8, and cooperating with the rollers on the transport frame 10, it is ensured that the denim fabric remains taut when being transported between the dryer 8 and the pre - shrinking main machine 2, preventing the fabric from curling, wrinkling, etc.

[0032] The above description is only a specific example of the present utility model and does not constitute any limitation to the present utility model. Obviously, for professionals in this field, after understanding the content and principle of the present utility model, various modifications and changes in form and details may be made without departing from the principle and structure of the present utility model. However, these corrections and changes based on the idea of the present utility model are still within the scope of protection of the claims of the present utility model.
