Description

Gypsum board limit spouts follow-up control device

Technical Field

The utility model relates to the technical field of follow-up control, in particular to a gypsum board side spraying follow-up control device.

Background

With the increasing importance of gypsum board appearance, the edge spraying effect is also an important appearance index. The former limit spouts the device just to fix the shower nozzle on the support, sprays the side of gypsum board, but because thistle board frequently makes a round trip to swing on the belt, and the shower nozzle that the limit spouts is only about 10 millimeters apart from the gypsum board, so the shower nozzle is frequently collided, not only influences the spray printing effect, still can damage the shower nozzle.

The existing gypsum board production vertical edge abnormality detection device (publication number: CN 215725893U) detects abnormal vertical edges through the vertical edge detection mechanism, and the vertical edge detection mechanism sends displacement to push the spray head positioning mechanism to drive the spray head to shrink to the side far away from the vertical edges when detecting the abnormal vertical edges, so that the inclined vertical edges are prevented from rubbing the spray head.

However, in actual production, when the gypsum board swings to the position of the spray head, overload is easy to occur on the positioning mechanism, the distance between the positioning mechanism and the edge of the gypsum board is not timely kept, the spray head is not timely retreated, and the spray head is damaged.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, the utility model provides a gypsum board edge spraying follow-up control device, which comprises a driving group 2 arranged on the side edge of a gypsum board conveyor belt 1, an edge spraying nozzle 3 and a distance meter 4 which are arranged on the end part on the same side of the driving group 2, a time delay detector 5 arranged between the edge spraying nozzle 3 and the conveyor belt 1, and a control component.

The driving group 2 is an air cylinder 201 and a stepping screw rod 202 arranged on the air cylinder 201, the distance meter 4 and the side spraying nozzle 3 are arranged on the stepping screw rod 202, and the stepping screw rod 202 drives the side spraying nozzle 3, the distance meter 4 and the time delay detector 5 to move in a direction far away from or close to the conveying belt.

The delay detector 5 is arranged between the side spraying nozzle 3 and the conveyor belt 1, and the delay detector 5 is fixedly arranged on the stepping screw rod 202 through the bracket 9 and moves along with the stepping screw rod 202. The delay detector 5 emits photoelectricity 6 to the periphery, and the photoelectricity 6 is arranged between the side spraying nozzle 3 and the conveyor belt 1, and a delay distance is reserved between the photoelectricity 6 side spraying nozzle 3.

Further, a delay detector 5 is arranged upstream of the side spraying nozzle 3, i.e. close to the feeding position of the plasterboard.

The control component may be a PLC.

Specifically, the distance meter 4 emits the distance measuring laser 7 to the side edge of the gypsum board 8 on the conveyor belt 1, the distance between the distance measuring laser 7 and the edge of the gypsum board 8 can be measured, and the distance is fed back to the PLC, i.e. the control component, which controls the operation of the stepping screw 202, so that the distance measuring laser 7 is always kept at a set distance, and thus, the edge spraying nozzle 3 always keeps a relatively constant distance with the edge of the gypsum board 8 along with the stepping action.

The step screw 202 is prevented from being overloaded and not kept at a set distance from the edge of the gypsum board 8 in time, and a photoelectric 6 is arranged in the direction of the coming side of the gypsum board, and the irradiation position of the photoelectric 6 is the gap position between the edge spraying nozzle 3 and the gypsum board.

Normally, the stepping screw 202 with these means is always kept at a distance from the edge of the plasterboard 8. If the photoelectric 6 irradiates on the gypsum board, the air cylinder 201 drives the stepping screw rod 202 to move in the direction away from the conveyor belt 1 to prevent the edge collision of the spray head 3, and after delay for 10 seconds, the stepping screw rod 202 slowly moves in the reverse direction to keep the edge spray head 3 at a set distance and spray printing normally.

The delay time may be absent, but may be 10 seconds in order to reduce the number of times the plasterboard strikes the photo 6.

The delay detector 5 may be located at any position but in order to prevent the plasterboard from striking the delay detector 5, the delay detector 5 is located higher than the highest point of the plasterboard on the conveyor belt or lower than the lowest point of the plasterboard on the conveyor belt.

By the gypsum board edge spraying follow-up control device, delay reaction time can be provided for the backward movement of the spray head, and the problem that the set distance between the spray head and the edge of the gypsum board cannot be kept due to overload of a device for adjusting the position of the spray head is prevented.

The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements may be made to the present application by those skilled in the art, which modifications and equivalents are also considered to be within the scope of the present application.
