Technical Field
[0001] The utility model belongs to the technical field of loom pre-shrinking machines, in particular to a vertical multi-channel cloth pre-shrinking machine. Background Art
[0002] As is known to all, among the existing fabric setting machine equipment, the preshrinking machine is a relatively common equipment, but the existing preshrinking machines all feed the fabric horizontally, that is, when the fabric enters the preshrinking machine, it enters the preshrinking machine for processing in a horizontal or inclined state. The disadvantages of this cloth feeding method are: 1. The weft slope of the fabric is easy to change, that is, when the fabric enters the preshrinking machine, its overall state is unstable. For example, if the left side of the fabric is in a taut state and the right side of the fabric is in a relaxed state, when the fabric enters the preshrinking machine through the expansion device in this state, the weft slope of the fabric will be changed during the preshrinking stage, affecting the fabric forming effect; 2. The existing fabric wrap angle is small, and the existing preshrinking heating module generally controls the wrapping angle of the fabric surface at about 180 degrees. This design leads to a reduction in the effective preshrinkage area of the fabric surface, and this preshrinkage efficiency needs to be improved.
[0003] In view of the above-mentioned technical disadvantages disclosed in this technical field, as researchers and developers in this industry, it is very necessary to improve the overall structure of the existing preshrinking machine, and improve the technical problem that the existing weft slope is easy to change through a new upper cloth structure. At the same time, the heating treatment efficiency of the cloth surface can be changed by changing the blanket covering area of the preshrinkage heating module and increasing the wrap angle.

It should be noted that the two groups of vertical expansion frames 3 are both vertically arranged on the front side of the machine 1.
[0027] When the utility model is in use, before the cloth enters the vertical expansion frame 3, it is in a suspended state, and the cloth surface is naturally relaxed, which can effectively avoid the change of the weft slope of the cloth in the pre-shrinking stage.
[0028] The upper part of the two vertical expansion frames 3 is provided with a steam box 6, and the steam box 6 is used for steam heating of the cloth before pre-shrinking. Figure 1 , 2 3, in order to improve the heating efficiency of the cloth, the steam box 6 is designed as follows: the steam box 6 is composed of a front box 61 and a rear box 64, a heating channel 62 is arranged between the front box 61 and the rear box 64, and a plurality of heating holes 63 are arranged toward the heating channel 62. In order to improve the passing efficiency of the cloth, the heating channel 62 is designed as a tapered structure, and the feeding port at the bottom is larger than the discharging port at the top.
