Technical Field

[0001] The utility model relates to the technical field of plate limiting, in particular to a plate limiting device for a plate extruder. Background Art

[0002] A sheet metal extruder is a machine that uses pressure to squeeze raw materials into sheet metal. The device uses two circular rollers, one for upper and one for lower extrusion. The lower extrusion roller is movably supported in a mounting bracket via shafts at both ends. Two pairs of parallel guide rails are fixedly mounted on the mounting bracket. Each pair of parallel guide rails has a bearing slider seat that can slide up and down within the parallel guide rails. The upper extrusion roller is supported in the bearing slider seat via connecting shafts at both ends.

[0003] However, in existing sheet metal extruders, sheets need to be conveyed between rollers via a conveyor for extrusion. During this time, the sheets may be slightly displaced due to machine vibration or other factors, thereby affecting the quality of the extruded sheets. Therefore, those skilled in the art have provided a sheet metal limiting device for a sheet metal extruder to address the problems raised in the above-mentioned background art. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a plate limiting device for a plate extruder to solve the problem that when conveying plates, the plates may be slightly displaced due to vibration of the machine or other reasons, thereby affecting the quality of plate extrusion.

[0006] Preferably, the bracket is slidably engaged with the limiting sliding grooves on both sides of the base through a clamping block.

[0007] When the motor drives the gear to rotate, the gear drives the tooth plates on both sides to move relative to each other, thereby causing the two brackets to move relative to each other, thereby achieving the effect of expansion or contraction. By overlapping the two sides of the plate on the bracket, it can cope with the clamping of plates of different specifications.

[0008] Preferably, a limit slot is provided on the tooth plate, and the tooth plate is slidably engaged with the card strip through the limit slot, and the limit slot is slidably engaged with the card strip corresponding to the bottom of the corresponding bracket to reduce the shaking of the tooth plate.

[0009] Preferably, the movable part is movably connected to the side plate, and the upper part of the roller is rotatably plugged into the movable part. When the roller is deformed by friction due to long-term use, the movable part can be disassembled and the roller can be replaced to avoid the problem of limit offset of the plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] Through the design, when the motor drives the gear to rotate, the gear drives the tooth plates on both sides to move relative to each other, so that the two brackets move relative to each other, thereby achieving the effect of expansion or contraction. It can cope with the clamping limit of plates of different specifications, and avoid the problem that the plates may be slightly displaced due to the vibration of the machine or other reasons, thereby affecting the quality of plate extrusion.
