Description

Technical Field

[0001] The utility model is applicable to the technical field of plywood processing, and particularly relates to a cutting and clamping mechanism for plywood. Background Art

[0002] At present, plywood is a three-layer or multi-layer plate material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesives. Usually, an odd number of veneers are used, and the fiber directions of adjacent veneers are glued perpendicular to each other. When further processing the plywood, the whole piece of plywood needs to be cut according to actual needs.

[0003] However, when cutting plywood nowadays, the operator often places the whole piece of plywood on the surface of the cutting platform, and then adjusts the limit clamping mechanisms on both sides of the operating platform step by step to make them push and reinforce the edges of the plywood. However, this adjustment operation method cannot position the plywood, and further, during the clamping adjustment process, not only does it increase the labor consumption of the operator for the distribution adjustment of the clamping mechanism, but it is also very easy to make the clamping adjustment unstable due to the single clamping direction, which affects the quality of subsequent cutting. Therefore, we propose a cutting clamping mechanism for plywood. Utility Model Content

[0004] The main purpose of the utility model is to provide a cutting and clamping mechanism for plywood, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A plywood cutting and clamping mechanism comprises a console, a mounting plate is fixedly mounted on the top surface of the console, support rods are vertically fixedly mounted on the four corner surfaces of the top of the mounting plate, a placing table is fixedly mounted between the tops of the support rods, and a bearing table is fixedly mounted on the middle end surface of the top of the placing table;

[0007] A hollow frame is fixedly installed on the middle end surface of the bottom of the placing table, a bidirectional screw is installed in the hollow frame for horizontal rotation through a bearing, a servo motor is fixedly installed on the side of the hollow frame, and the side of the servo motor transmission shaft is fixedly connected to the outer top end of the bidirectional screw through a coupling, and transmission sleeves are movably sleeved on the outer end surfaces of the bidirectional screw, and a connecting block is fixedly installed on the top surface of each transmission sleeve, and the connecting block is slidably installed in the hollow frame and the placing table, and a fixing plate is fixedly installed on the top surface of each connecting block, and a limit frame is fixedly installed on the side of each fixing plate, and the bottom of the limit frame and the top surface of the bearing platform are at the same horizontal position;

[0008] A fixing frame is fixedly installed on the outer surface of the top of each limit frame, an electric push rod is fixedly installed inside each fixed frame, and a clamping plate is fixedly installed on the bottom surface of the electric push rod transmission shaft, and the clamping plate is movably installed on the inner top of the limit frame.

[0009] By adopting the above technical scheme, the limit frame can be adjusted horizontally and the abutment plate can be adjusted vertically through the rotation transmission action of the bidirectional screw on the transmission sleeve and the driving action of the electric push rod, so that the plywood to be cut can be abutted and reinforced from the side and vertical position, thereby improving the stability of the abutment and reinforcement of the plywood and reducing the labor consumption of the operator for manual adjustment.

[0010] As an optional solution of the technical solution of the present application, a sliding guide rail is installed on the side of the mounting plate, a driving arm is installed on the top of the sliding guide rail, and a cutting tool holder is installed on the bottom surface of the driving arm.

[0011] By adopting the above technical solution, the position of the cutting knife holder can be adjusted through the driving arm and the sliding guide rail, so the cutting position can be adjusted.

[0012] As an optional solution of the technical solution of the present application, guide grooves are provided on both sides of the top of each limit frame, and guide rods are vertically fixedly installed on both sides of the top of each clamping plate, and the guide rods are slidably installed inside the guide grooves.

[0013] By adopting the above technical solution, the rationality of the transmission adjustment of the entire device is ensured through the guiding sliding action of the guide groove on the guide rod.

[0014] As an optional solution of the technical solution of the present application, a limiting groove is provided inside the middle end of the placement table, and the connecting block is slidably installed inside the limiting groove.

[0015] By adopting the above technical solution, the rationality of the rotation transmission of the bidirectional screw to the transmission sleeve is ensured by the guiding sliding action of the limit groove on the connecting block.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. A cutting and clamping mechanism for plywood according to the technical solution of the present application, wherein a transmission sleeve is sleeved on the outer side of a bidirectional screw rod, so that when the bidirectional screw rod is driven by a servo motor to rotate inside a hollow frame, the bidirectional screw rod can drive two sets of transmission sleeves and the limit frames connected thereto for transmission above to move synchronously horizontally toward or relative to each other, so that the two sets of limit frames can synchronously move horizontally on the surface of a placement table to perform a dynamic reinforcement treatment on both sides of the edge of the plywood to be cut, and then adjust the vertical position of the clamping plate inside the limit frame in combination with the driving action of the electric push rod, thereby further improving the stability of the dynamic reinforcement of the plywood from multiple directions and reducing the labor consumption required for manual adjustment by the operator.

[0018] 2. The technical solution of the present application is a plywood cutting and clamping mechanism, which inserts a limit block into a limit groove and combines the guiding and limiting effect of the limit groove on the limit block, so that when the bidirectional screw rotates, the transmission sleeve can only move horizontally and will not rotate axially, thereby ensuring the rationality of the transmission required for the horizontal movement adjustment of the limit frame.
