Description

Technical Field

[0001] The invention relates to a rear-mounted swing-bar drum slicer. Background Art

[0002] Drum chipper is a commonly used equipment for wood chipping. Its working principle is as follows: the high-speed rotating knife roller drives the flying knife. Under the action of the flying knife and the bottom knife, the garden wood is cut into flakes, thus meeting the requirements of artificial board and papermaking.

[0003] The existing drum chipper mainly includes a conveying mechanism, a feeding mechanism and a chipping mechanism. The feeding mechanism is arranged between the conveying mechanism and the chipping mechanism, and is used to feed materials (wood, branches, etc. that need to be chipped) into the chipping mechanism, and the flying knives on the knife roller chip the materials.

[0004] Since the materials processed by the drum chipper are of different sizes, the feed mechanism needs to automatically adjust the pressing position according to the materials to ensure that the materials are stably located at the feed port of the chipper. The feed mechanism of the existing drum chipper has a limited adjustment range and can only process materials of a certain specification. When the materials exceed the above specifications, the cutting effect is not ideal. Summary of the invention

[0005] The object of the present invention is to provide a rear-mounted swing arm drum slicer which is applicable to materials of different sizes and has good slicing effect.

[0006] The object of the present invention is achieved through the following technical scheme: a rear-mounted swing arm drum slicer, which includes a drum slicing mechanism and a conveying mechanism arranged at a feeding port on the front side of the drum slicing mechanism, wherein a rear-mounted swinging mechanism and a material pressing mechanism are arranged on the upper side of the conveying mechanism; the rear end of the rear-mounted swinging mechanism is hinged on one side of the drum slicing mechanism, and its hinge axis is parallel to or coincides with the blade rotation axis of the drum slicing mechanism; the material pressing mechanism is connected to the rear-mounted swinging mechanism, and the rear end pressing part of the material pressing mechanism forms an inscribed, contained or concentric relationship with the circle formed by the rotation of the rear-mounted swinging mechanism and the circle formed by the rotation of the blade in the drum slicing mechanism.

[0007] Compared with the prior art, the advantages of the present invention are:

[0008] 1. The present invention arranges a rear swing mechanism and a pressing mechanism on the upper side of the conveying mechanism, the pressing mechanism is connected to the rear swing mechanism, and the pressing portion at the rear end of the pressing mechanism forms an inscribed, contained or concentric circle relationship with the circle formed by the rotation of the rear swing mechanism and the circle formed by the rotation of the blade in the drum slicing mechanism. The rear swing mechanism can automatically swing along the hinge axis according to the size of the material, so that the pressing mechanism always presses on the upper side of the material, and cooperates with the conveying mechanism on the lower side to stably convey the material to the front feed port of the drum slicing mechanism; and the pressing mechanism swings close to the blade of the slicer near the feed port, so as to always maintain the pressing force on the material on the lower side.

[0009] 2. The rear swing mechanism includes a main swing frame and an auxiliary swing frame. The front part of the auxiliary swing frame is hinged on the main swing frame. An elastic component is also provided between the main swing frame and the auxiliary swing frame. The elastic component can press down the free swinging end of the rear part of the auxiliary swing frame to make the pressing mechanism closer to the upper side of the material. In addition, the auxiliary swing frame is more sensitive to reaction and can quickly handle small size changes of the material.

[0010] 3. A pressing roller mechanism is also provided on the front side of the rear swing mechanism, which can perform preliminary squeezing on loose or hollow materials. The materials after squeezing are harder and more convenient for subsequent slicing operations. BRIEF DESCRIPTION OF THE DRAWINGS
