The leather can be automatically sprayed by the equipment provided by the invention, and the specific processing process can be seen as follows.
The leather is automatically retracted, pulled and conveyed through the existing retraction roller equipment, and the surface to be sprayed of the leather faces downwards in the conveying process, so that the leather is kept in an open and tight state, and the leather is ensured to be in an optimal spraying state.
When the leather is conveyed through the spraying cleaning mechanism 2, one cleaning roller 222 is at the highest position, the brush hair is closely attached to the surface to be sprayed of the leather, the surface to be sprayed of the leather is brushed and cleaned through the rotation of the cleaning roller 222, the other cleaning roller 222 is at the lowest height position and keeps rotating at a constant speed, and the cleaning roller 222 cleans and washes the whole brush hair in the rotating process through the cleaning brush needle 243 and the pressurized steam airflow accompanied with spraying.
When leather is conveyed to the reciprocating spraying mechanism 3 from the spraying cleaning mechanism 2, under the driving of the driving component 34, the driving connecting rod 343 drives the sliding seat plate 32 to slide reciprocally along the sliding groove 311, so that the two rows of rotary spray heads 33 are driven to synchronously move along with the sliding seat plate 32, and the rack 312 enables the rotary spray heads 33 to passively rotate reciprocally through the meshed gear ring 331 while moving, so that the two rows of rotary spray heads 33 keep reciprocating rotation while moving reciprocally, and therefore, intermittent conveying stopping leather sections can be covered and sprayed evenly, and the uniformity of spraying coverage is greatly improved.
The sprayed leather can be rolled again after being dried in the process of continuous conveying.
In addition, in the process of reciprocating spraying of the reciprocating spraying mechanism 3, the sliding seat plate 32 which slides reciprocally is driven by the connecting rod swinging frame 23 to switch the positions of the two cleaning members 22 up and down through the linkage mechanism 4, specifically, as seen in fig. 2, 3 and 8, when the sliding seat plate 32 slides from right to left, the ball pin 45 is located in a horizontal section 471 of the upper position of the annular rail groove 47 in fig. 3 in fig. 2, the cleaning roller 222 on the left is located at the lowest position, the cleaning roller 222 on the right is located at the highest position, the tension spring 42 is located in an elongated state, the pulling rotating plate 41 is pulled to rotate downwards, the annular rail groove 47 and the connecting frame 46 slide synchronously with the sliding seat plate 32 to the left, so that the ball pin 45 moves relatively to the right along the upper horizontal section 471 of the annular rail groove 47, when the sliding seat plate 32 slides to the leftmost position in fig. 2, the ball pin 45 moves relatively to the rightmost end of the horizontal section 471 above the annular rail groove 47, and as shown in fig. 8, under the tension of the tension spring 42, the tension spring 42 automatically returns to the balanced stress state, namely, the ball pin 45 passes through the vertical section 4721 of the right switching section 472 instantly, moves to the position where the vertical section 4721 is tangential to the circular arc section 4722, two cleaning rollers 222 are at the same height in fig. 3, then when the sliding seat plate 32 slides from left to right, the annular rail groove 47 moves synchronously to the right, at this moment, the ball pin 45 moves relatively to the left, but the ball pin 45 cannot pass through the right vertical section 4721, so that the ball pin can only enter the horizontal section 471 below the annular rail groove 47 along the circular arc section 4722 on the right, at this moment, the tension spring 42 is in the compressed state, the cleaning roller 222 on the left in fig. 3 rises to the highest position, switches to the height which can clean leather in a fitting manner, the right cleaning roller 222 is lowered to the lowest height for cleaning, and accordingly, when the ball pin 45 passes over the left switching section 472 and enters the upper horizontal section 471 again, the positions of the two cleaning rollers 222 are switched again, and then, with the sliding frequency of the sliding seat plate 32, the positions of the two cleaning rollers 222 are switched synchronously and alternately. Through the intermittent type cooperation of two cleaning rollers 222, under the serial connection drive of interlock mechanism 4, can accompany reciprocal spraying mechanism 3 to carry out the reciprocal automatic switch-over of altitude position, on the one hand under the prerequisite that does not influence leather surface clearance, realize the automatic clearance in turn of two cleaning rollers 222, self-cleaning frequency is high, the clearance is more timely, the accumulation of more spot on cleaning roller 222 has been avoided, the degree of difficulty of self-cleaning has been reduced, the high efficiency of cleaning roller 222 to leather clearance has been maintained, on the other hand, the distance of pulling apart two cleaning rollers 222 through the mode of vertical dislocation, the cleaning roller 222 that avoids carrying out leather clearance and the cleaning roller 222 that carries out self-cleaning mutually interfere, avoid cleaning roller 222 self-cleaning in-process spot to get back to the leather surface again.
In addition, as shown in fig. 9, the invention also provides an automatic spraying method for leather processing, which comprises the following steps: s1, enabling the surface to be sprayed of the leather to face downwards, and carrying out traction conveying on the leather in a tightening and opening state.
S2, automatically cleaning the surface to be sprayed of the leather before spraying through a spraying cleaning mechanism 2 in the conveying process.
S3, spraying the cleaned leather surface to be sprayed reciprocally and uniformly through a reciprocal spraying mechanism 3.
S4, winding again after the leather spraying surface is dried.
