Description

Technical Field

[0001] The utility model belongs to the technical field of artificial leather production, and particularly relates to a cleaning device for a base cloth in artificial leather production. Background Art

[0002] The utility model patent with the application number 202111527733.7 discloses an automatic loading and unloading cloth opening machine for pre-treatment in artificial leather production. The following problems exist in the internal structure of the cloth opening box during actual production:

[0003] 1) The base cloth passes through the cloth opening box from front to back. After the fixed cleaning roller and the moving cleaning roller of the impurity cleaning roller group clean the impurities on the upper and lower surfaces of the base cloth, the dust extraction hood extracts the brushed impurities. The dust extraction hood is arranged on the top of the cloth opening box. Due to the blockage of the base cloth, the impurities at the bottom of the cloth opening box are difficult to be extracted.

[0004] 2) The impurity cleaning roller group is arranged at the rear side of the cloth pressing roller group, and the dust extraction hood is arranged at the front side of the impurity cleaning roller group. The impurities brushed off the base cloth by the impurity cleaning roller group will still adhere to the surface of the base cloth at the rear side of the impurity cleaning roller group, resulting in poor impurity cleaning operation effect.

[0005] 3) The air outlet of the blower does not blow directly against the surface of the base cloth, so the loosening effect on the base cloth fibers is poor, and it is difficult to clean the impurities adhered to the surface of the base cloth, affecting the impurity removal and cleaning quality.

[0006] 4) The adjusting screw rods connected to the upper ends of the moving pressure roller and the moving cleaning roller pass through the top of the cloth opening box. Under the action of the spring, the lower parts of the moving pressure roller and the moving cleaning roller are both pressed against the base cloth. The moving pressure roller and the moving cleaning roller will float up and down. Since there is no guide sleeve arranged at the top of the cloth opening box, the stability of the moving pressure roller and the moving cleaning roller during operation is poor, and there will be a large amount of front-back shaking, thus affecting the operation effects of the cloth pressing roller group and the impurity cleaning roller group.

[0014] The structures of the first up-and-down floating guiding component and the second up-and-down floating guiding component are the same;

[0015] Both the first up-and-down floating guiding component and the second up-and-down floating guiding component include a guide sleeve, a guide rod, a spring, a first locking nut, a second locking nut, a third locking nut and a rubber buffer pad; a vertically penetrating threaded hole is provided at the top of the box body, the outer circle of the guide sleeve is threadedly connected to the threaded hole, the first locking nut is threadedly connected to the outer circle of the guide sleeve and is pressed against the top of the box body, the guide rod is slidably connected inside the guide sleeve, the second locking nut and the third locking nut are both threadedly connected to the outer circle of the upper end of the guide rod, the rubber buffer pad is sleeved on the guide rod, the lower end of the rubber buffer pad is fixedly arranged on the upper end surface of the guide sleeve, the lower end surface of the second locking nut is pressed against the upper end surface of the third locking nut, and the lower end surface of the third locking nut is in contact with the upper end surface of the rubber buffer pad sleeve; the spring is sleeved on the guide rod, and the upper end of the spring is pressed against the lower end surface of the guide sleeve;

[0017] A cloth guiding wheel is arranged on the front side of the box body and is located below the cloth inlet.

[0018] Adopting the above technical solution, the working principle and technical effects of the present utility model are specifically as follows:

[0019] 1) A cloth pressing driving device for driving the cloth pressing roller group to rotate and an impurity cleaning driving device for driving the impurity cleaning roller group to rotate are provided on the left side or the right side of the box body. The cloth pressing driving device and the impurity cleaning driving device are conventional existing technologies, and each roller is independently driven by a motor.

The left dust extraction hood and the right dust extraction hood are connected to the dust extraction pipe, and a negative pressure blower is connected to the dust extraction pipe.

[0020] 2) The base cloth passes through the upper part of the cloth guiding wheel and enters the cloth opening box through the cloth inlet. First, the impurities attached to the surface of the base cloth are cleaned by the bristles on the rotating fixed pressing roller and the floating pressing roller. Then, the high-pressure hot air blows to the surface of the base cloth through a plurality of fan-shaped air nozzles arranged on the air blowing pipe. The high-pressure hot air ejected by the fan-shaped air nozzles completely covers the width direction of the base cloth. The hot air loosens the fibers of the base cloth, and the wrinkles of the base cloth are unfolded. At the same time, the high-pressure hot air blows up the impurities adhered to the surface of the base cloth, achieving the effect of deeply cleaning the base cloth. After the tiny and light impurities on the surface of the base cloth are cleaned and blown up by the high-pressure hot air, under the action of the negative pressure blower, the light impurities are extracted from the box body by the left dust extraction hood and the right dust extraction hood. The surface-cleaned base cloth then passes through the cloth pressing roller group, and the base cloth is further flattened. The fixed pressing roller and the floating pressing roller also play the function of clamping the base cloth and conveying it backward. Finally, the cleaned and flattened base cloth is conveyed (wound up) backward through the cloth outlet.

[0021] 3) For the base fabric of the present utility model, it is first cleaned by a roller brush, then deeply cleaned by high-pressure hot air, and finally the base fabric is completely flattened. This operation method of opening and cleaning the fabric is more scientific, greatly improving the cleaning effect of the base fabric coming out after passing through the fabric opening box.

[0022] 4) In order to prevent light impurities from floating to the rear side of the box body and adhering to the surface of the base fabric at the fabric outlet, an upper dust baffle located above the base fabric and a lower dust baffle located below the base fabric can be provided at the rear ends of the left dust extraction hood and the right dust extraction hood.

[0023] 5) The settings of the first up-and-down floating guiding component and the second up-and-down floating guiding component not only facilitate installation and disassembly, but also ensure that the guide rods connected to the upper ends of the floating impurity removal roller and the floating pressing roller can only slide vertically within the guide sleeves, thereby ensuring that the floating impurity removal roller corresponds to the fixed impurity removal roller up and down, improving the impurity removal effect of the roller brush, and the floating pressing roller corresponds to the fixed pressing roller up and down, improving the flattening and clamping and conveying effects of the base fabric.

[0024] 6) The first locking nut is threadedly connected to the outer circle of the guide sleeve and presses against the top of the box body to ensure the firmness of the fixation between the guide sleeve and the top of the box body. The second locking nut and the third locking nut can be adjusted in position on the guide rod to adjust the elastic force of the spring, thereby adjusting the pressing degree of the floating impurity removal roller or the floating pressing roller on the base fabric. The rubber buffer pad serves to reduce the impact vibration of the third locking nut on the top of the box body during up-and-down floating.

[0025] In summary, the principle of the present utility model is scientific, the structure is compact, the stability during the operation of the impurity removal roller group and the cloth pressing roller group is improved, and a two-layer cleaning method of roller brush and high-pressure blowing is adopted, greatly enhancing the impurity removal and flattening effects of the base fabric in the fabric opening box.

[0039] 1) A cloth-pressing driving device for driving the rotation of the cloth-pressing roller group and a impurity-removing driving device for driving the rotation of the impurity-removing roller group are provided on the left or right side of the box body 1. The cloth-pressing driving device and the impurity-removing driving device are conventional existing technologies, and each roller is independently driven by a motor.
