Abstract
The invention relates to the field of stripping devices, and provides a foam release paper stripping mechanism for stably stripping foam in order to overcome the defect that the foam is broken in a mode of breaking vacuum wholly and drawing the foam due to the fact that a vacuum sucker breaks vacuum locally. The vacuum sucker comprises a bottom plate, a metal wire and a sucker mechanism, wherein the sucker mechanism comprises a flexible porous medium layer, a supporting plate, a guide plate, a shell and a vacuumizing device. When the foam is separated, the metal wire is arranged between the lower surface of the foam and the release paper, the flexible porous medium layer of the sucker mechanism is arranged on the upper surface of the foam, and the foam and the release paper are separated by adopting a secondary stripping method. The invention can avoid the whole vacuum breaking and enhance the adsorption force when the local vacuum breaking of the sucker mechanism; when the foam is pulled, the situation that the foam is lengthened or folded due to the fact that the foam is broken due to overlarge traction force is avoided.
Description
Technical Field
The invention relates to the technical field of stripping devices, in particular to a foam release paper stripping mechanism and a stripping method thereof.
Background
In the manufacturing industry, the foam is widely applied to various fields such as metal surfaces, wood surfaces, glass surfaces and the like. When the foam comes, the foam is divided into blocks with the same size, and the blocks are adsorbed on release paper, and the foam is required to be stripped from the release paper when in use. The common stripping method is a cylinder claw clamp stripping method, the cylinder claw clamp stripping method is a mechanical stripping method which uses a cylinder claw clamp to clamp foam and moves upwards to strip the release paper from the foam, and the foam is easily distorted or deformed when the foam is stripped by the method.
For example, a "foam separation device" disclosed in chinese patent document, publication No. CN 206345116U, includes: the placing part is used for placing foam, and a film is attached to one side surface of the foam; the pressing part is arranged above the placing part and is used for pressing the foam towards the placing part; and the roller part is arranged below the placing part and comprises two rollers which are arranged in parallel and pressed against each other. The device enables the foam and the film to form a certain opening angle through pressing of the pressing part and clamping of the roller part, so that the foam can be quickly and conveniently peeled off from the film. The problem that the way of drawing the foam can damage the foam and can cause the foam to be elongated or to be wrinkled is not solved.
Disclosure of Invention
One purpose of the invention is to overcome the problem that the vacuum is broken wholly due to the partial vacuum breaking of the vacuum chuck; the foam is broken by drawing the foam, so that the foam is elongated or folded, and the foam release paper stripping mechanism for stably stripping the foam is provided.
Another object of the present invention is to overcome the overall vacuum break caused by the partial vacuum break of the vacuum chuck; the foam is broken by drawing the foam, so that the foam is elongated or folded, and the foam release paper stripping mechanism and the stripping method thereof for stably stripping the foam are provided.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a bubble cotton is from type paper stripping off mechanism, includes the bottom plate, still includes wire and sucking disc mechanism, sucking disc mechanism includes flexible porous dielectric layer, layer board, guide plate, shell and evacuating device, the layer board lower surface links to each other with flexible porous dielectric layer, and the upper surface is connected with the shell and is formed hollow structure, and the layer board upper surface is equipped with a plurality of guide plates of perpendicular to layer board, and the space between guide plate and the shell forms the evacuation passageway, be equipped with the evacuation hole on the layer board, evacuation hole and guide plate alternate arrangement on the layer board, and communicate with the evacuation passageway, the shell top is equipped with the opening, and evacuating device is connected to the opening.
The mode that the metal wire is cut into the gap between the foam and the release paper is easy to realize in the mode, and meanwhile, the release paper cannot be damaged. The sponge sucker is used for stripping the foam, so that the condition that the common vacuum sucker breaks vacuum due to poor alignment with the foam is avoided, and the stripping strength of the edge of the foam is also improved.
Preferably, the flexible porous medium layer is a sponge layer. The sponge layer has flexibility and sealing performance, the shape of the foam is not damaged, and the contact surface of the sponge layer and the foam surface can be optimized along with the change of the shape of the foam.
The foam is peeled off the foam and is released from type paper stripping mechanism, and the concrete step of peeling off includes:
(1) primary stripping: the metal wire is cut into the gap between the foam and the release paper from the edge between the lower surface of the foam and the release paper and reciprocates to destroy the adsorption force between the foam and the release paper, so that the adsorption force between the foam and the release paper is greatly reduced, the mode of cutting the metal wire into the gap between the foam and the release paper is easy to realize, and the release paper is not damaged;
(2) secondary stripping: and removing the metal wires, placing the foam on the bottom plate, placing the flexible porous medium layer of the sucker mechanism on the upper surface of the foam, pressing the sucker mechanism downwards, keeping the sucker mechanism unchanged, and controlling the bottom plate to move while stripping the release paper from the foam along with the bottom plate. The sponge sucker is used for stripping the foam, so that the condition that the vacuum is broken due to the bad degree of the common vacuum sucker and the foam is avoided, and the stripping strength of the edge of the foam is improved
Preferably, the wire diameter is less than the foam thickness. Too large diameter of the metal wire can easily damage the part of the foam and the release paper which are connected, and the metal wire is difficult to cut into the part from the edge of the foam, and the diameter of the metal wire is small, so that the foam and the release paper can be better peeled.
Preferably, the area of the flexible porous medium layer of the sucker mechanism is larger than that of the foam. When the size of the sponge sucker is smaller than that of the foam, the sponge sucker cannot adsorb the foam due to insufficient adsorption force caused by incomplete coverage.
Preferably, the pressing distance of the sucker mechanism is not more than half of the thickness of the foam. So as to avoid the change of the shape of the foam caused by the overlarge pressing distance caused by the overlarge pressing pressure.
Preferably, the speed of the movement of the bottom plate is 8m/s-20 m/s. The too low moving speed of the bottom plate can cause the insufficient peeling force of the release paper, so that the release paper can not be peeled; too fast moving speed of the bottom plate can cause the release paper to be easily torn, and peeling of the release paper can be affected.
Therefore, the invention has the following beneficial effects: (1) when the vacuum sucker is locally broken, the whole broken vacuum cannot be caused, so that the adsorption force is reduced; (2) when the foam is pulled, the foam is prevented from being elongated or folded due to the fact that the foam is broken due to overlarge traction force; (3) the secondary stripping method improves the stripping reliability of the foam.
