Description

TECHNICAL FIELD

[0001] The utility model belongs to the production technology field of artificial leather, and particularly relates to a pneumatic rapid positioning anti-rollover device. BACKGROUND

[0002] In the foaming production process of artificial leather, a pattern roller is used to suck full patterns on the surface of the artificial leather, the pattern roller is installed on a pattern roller trolley, four wheels are installed under the bottom frame of the pattern roller trolley, the pattern roller trolley can be pushed in or pulled out along two parallel horizontal rails fixed on the ground, the horizontal rails are arranged in the left-right direction, and the horizontal rails are located at the rear side of a foaming furnace, so that the pattern roller trolley is also parallel to the foaming furnace. In addition, the wheels of the pattern roller trolley need to be positioned after being pushed into position along the horizontal rails, so that the center line of the pattern roller trolley is kept coincident with the center line of the foaming furnace. At present, the following method is used to position the pattern roller trolley: after the pattern roller trolley is moved into position along the horizontal rails, the position of the pattern roller trolley needs to be adjusted repeatedly, which is quite cumbersome. An inclined iron block is placed in the angle between the wheels and the ground to prevent the pattern roller trolley from moving left and right during production. During production, the inclined iron block moves due to the lack of positioning, and the pattern roller trolley is displaced on the horizontal rails, which further causes problems in the pattern sucking process of the artificial leather, and even causes batch waste. When the pattern roller trolley needs to be pulled out of the horizontal rails, the inclined iron block needs to be removed first, and then the trolley is pulled out of the horizontal rails. The pattern roller on the pattern roller trolley is replaced outside the foaming furnace production line.

[0003] The patent with the authorization announcement number CN205653609U discloses an anti-pulling-over device for a pattern roller trolley, which mainly prevents the pattern roller trolley from being pulled over by pulling between the first angle iron and the second angle iron. However, the patent technical solution does not have a positioning arrangement in the horizontal rail direction (left-right direction). CONTENT OF THE UTILITY MODEL

[0028] The contact surface between the front side surface of the vertical clamping plate 7 and the rear side surface of the upper part of the L-shaped positioning block 2 is an inclined surface 11 which is inclined from high to low and rearward.

[0029] The transverse plate 6, the vertical clamping plate 7 and the dovetail sliding block 9 are fixedly connected as a whole by welding; the transverse plate 6 is fixedly connected with the V-shaped positioning block 8 as a whole by means of a countersunk bolt 12 which is vertically and downwardly arranged; and the L-shaped positioning block 2 is integrally welded by two steel plates which are horizontal and vertical.
