Description

Technical Field

[0001] The utility model relates to the field of rotary cutters, in particular to a tail plate cutting device for rotary cutters. Background Art

[0002] The veneer strips peeled by the peeling machine are cut into veneers after cutting, and the veneers are sent out through the conveyor belt at the rear; when the peeling machine peels to the tail board (that is, the last veneer), the driving roller of the peeling machine needs to stop working and perform the wood core beating operation. After the wood core falls, the tail board in the peeling machine lacks thrust, and only a section of the rear part of the tail board is on the conveyor belt, resulting in insufficient friction between the conveyor belt and the tail board to send the tail board out, and the tail board is prone to get stuck in the peeling machine. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a rotary cutter tail plate cutting operation device which has a simple structure, is easy to use and has strong practicality, and can realize the discharge of the material by pulling the tail plate backwards, and avoid the tail plate being stuck in the rotary cutter.

[0004] The utility model is implemented by the following scheme: a cutting operation device for the tail plate of a rotary cutter, comprising a discharge conveyor belt located at the rear side of the rotary cutter, a cutting mechanism being arranged at the front end of the discharge conveyor belt; the cutting mechanism comprising knife seats at two sides, a support roller and a rotating knife holder located above the support roller being rotatably connected between the knife seats at the two sides, a cutting knife being installed on the rotating knife holder; a pressing roller shaft which can move up and down and can press on the discharge conveyor belt when moving down is arranged at the rear of the rotating knife holder.

[0005] Furthermore, the two ends of the rotating tool holder are rotatably connected to the tool seats on both sides through a connecting shaft, and the connecting shafts at both ends of the rotating tool holder are provided with swing arms that can rotate relative to them, and the two ends of the pressing roller shaft are connected to the swing arms, and a lifting cylinder is provided above the swing arm for driving the swing arm to swing up and down.

[0006] Furthermore, a plurality of pressing wheels are spaced apart on the pressing roller shaft.

[0007] Furthermore, threaded shafts are provided at both ends of the pressing roller shaft, and a long hole for the threaded shaft to pass through is provided on the swing arm. The threaded shaft is locked by a nut after passing through the long hole.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the tail plate cutting operation device of the rotary cutter of the utility model has a simple structure, is easy to use, and has strong practicality. It controls the pressing roller to move downward so that it presses on the tail plate, thereby increasing the friction between the tail plate and the discharge conveyor belt, thereby realizing the tail plate being pulled backward to realize discharge, and avoiding the tail plate being stuck in the rotary cutter.

DETAILED DESCRIPTION

[0014] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0015] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0016] like Figures 1 to 3 As shown, a tail plate cutting device for a rotary cutter includes a discharge conveyor belt 100 located at the rear side of the rotary cutter, and a cutting mechanism 200 is provided at the front end of the discharge conveyor belt 100; the cutting mechanism 200 includes knife seats 210 on both sides, and a support roller 220 and a rotating knife holder 230 located above the support roller are rotatably connected between the knife seats on both sides, and a cutting knife 231 is installed on the rotating knife holder; a pressing roller shaft 240 that can move up and down and can press on the discharge conveyor belt when moving down is provided at the rear of the rotating knife holder 231. When the tail plate (i.e., the last single board) of the rotary cutter of the utility model is discharged, the pressing roller shaft 240 is controlled to move down to press on the tail plate, thereby increasing the friction between the tail plate and the discharge conveyor belt 100, thereby realizing the discharge of the tail plate by pulling the tail plate backwards, and preventing the tail plate from being stuck in the rotary cutter.

[0017] In this embodiment, the two ends of the rotating tool holder 230 are rotatably connected to the tool holders 210 on both sides through the connecting shaft 232. The connecting shafts at both ends of the rotating tool holder are provided with swing arms 250 that can rotate relative to the swing arms. The two ends of the pressing roller shaft are connected to the swing arms. A lifting cylinder 260 is provided above the swing arms to drive the swing arms to swing up and down. The two ends of the pressing roller shaft 240 are connected to the two ends of the rotating tool holder 230 through the swing arms, and are driven by the lifting cylinder 260 to swing up and down. Except when processing the tail plate, the pressing roller shaft 240 is in a downward swing state and pressed on the rear of the tail plate; in the rest of the single board processing process, the pressing roller shaft 240 is in an upward swing state and does not participate in the work.

[0018] In this embodiment, a plurality of pressing wheels 241 are provided at intervals on the pressing roller shaft 240, and the pressing wheels 241 use bearings. The main function of the pressing roller shaft 240 is to provide pressure and increase the friction between the tail plate and the discharge conveyor belt. By providing the pressing wheels 241 to achieve rolling contact with the tail plate, the friction between the tail plate and the tail plate can be reduced. In the specific implementation process, the two ends of the pressing roller shaft 240 can also be rotatably connected to the swing arm so that the pressing roller shaft 240 can rotate, or the pressing wheels may not be provided.

[0019] In this embodiment, threaded shafts are provided at both ends of the nip roller shaft, and a long hole is provided on the swing arm for the threaded shaft to pass through. The threaded shaft is locked by a nut after passing through the long hole. After loosening the nut, the position of the nip roller shaft can be adjusted by moving the threaded shaft in the long hole, and the nut can be tightened after the adjustment is completed.
