A high-speed servo tape cutting device for edge sealing process

Abstract

This utility model relates to the field of edge banding machine technology, and in particular to a high-speed servo cutting device for edge banding process, including a drive mechanism, a cam linear cutting mechanism and a knife holder fixing mechanism. The mechanisms are mechanically linked by a cam mechanism to make eccentric motion. When the servo motor operates at high speed in one cycle (1 rotation), it drives the cam to rotate. The cam pushes against the connecting rod, causing the cutter fixed on the cutter holder to reciprocate horizontally. The cutter cuts the edge banding at high speed. The blade adopts a beveled edge, which is conducive to segmented cutting. The mechanism design can swing according to the direction of the edge banding input, and track synchronously at the moment of high-speed cutting to avoid the edge banding tail corner falling off. The power mechanism adopts high-speed absolute value servo control, which is accurate in positioning and fast in response, making the cutting accuracy more precise and the reserved length of the edge banding end shorter, thus saving materials.

Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, specifically a high-speed servo tape cutting device for edge banding process. Background Technology

[0002] In the woodworking industry, especially in the process of edge banding panels, the operating speed of traditional edge banding machines is generally low. During the production process, the speed of board conveying and the cutting speed of edge banding tape feeding can be achieved with a general pneumatic cutter.

[0003] However, the existing technology has the following drawbacks:

[0004] However, as customers demand higher production efficiency, high-speed edge banding machines have emerged to meet their needs. Under high-speed and high-efficiency production, ordinary pneumatic cutters can no longer match the cutting speed of the edge banding tape, which will cause the edge banding tape to be dragged, resulting in short tape and debris, affecting production quality. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed servo tape cutting device for edge sealing processes, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-speed servo tape cutting device for edge sealing process, comprising a drive mechanism, a cam linear tape cutting mechanism, and a knife holder fixing mechanism. The drive mechanism includes a main bearing housing and a servo motor. The main bearing housing has a mounting hole in the middle and a bearing inside the mounting hole. An eccentric cam roller is provided on the outer side of the output end of the servo motor. The eccentric cam roller is inserted into the bearing. Clamping plates are provided at both ends of the main bearing housing away from the side. The cam linear tape cutting mechanism includes a cutter holder. One end of the cutter holder is clamped between the two clamping plates and is fixedly connected to the main bearing housing. A cutter is mounted on the side of the cutter holder near the main bearing housing. The knife holder fixing mechanism includes a fixing frame. Screws and springs are installed inside the side of the fixing frame, and the fixing frame is locked and fixed to the cutter holder by screws.

[0007] Using the above technical solution, the board is placed in the edge banding machine through the feed inlet with a guide ruler. After the board passes through the pre-milling unit and the gluing unit, the corresponding edge banding is fed out by the tape feeding device. After the edge banding is attached to the board and the edge is sealed, the high-speed conveying is completed. After the servo motor runs one revolution, the cutter cuts the edge banding tape instantly.

[0008] The main bearing housing has a motor mounting cover on the side near the servo motor, and the motor mounting cover presses against the outer ring of the bearing. The end of the servo motor near the main bearing housing is fixedly connected to the motor mounting cover. The shape and size of the motor mounting cover are the same as the cross-sectional shape and size of the servo motor. A through hole is opened in the middle of the motor mounting cover, and the inner diameter of the through hole is the same as the inner diameter of the bearing.

[0009] Using the above technical solution, the motor mounting cover serves to connect and fix the servo motor to the main bearing housing.

[0010] Both ends of the mounting hole of the main bearing housing are provided with retaining rings, and the bearing is engaged between the two retaining rings. The eccentric cam roller is screwed into the set screw to tighten the flat key of the motor output shaft. The outer circle of the eccentric cam roller is fixedly installed with a retaining ring, and the retaining ring is interference-fitted into the inner ring of the bearing.

[0011] The above technical solution uses a snap ring to limit the bearing, preventing it from shaking or shifting within the mounting hole and maintaining stable rotation.

[0012] The front end of the cutter holder is equipped with an auxiliary blade, and the rear end is equipped with an oil injection nozzle. The middle part of the end of the cutter near the oil injection nozzle is provided with a long groove, and the eccentric cam roller is engaged in the long groove. The two ends of the middle part of the cutter holder near the main bearing seat are provided with linear blocks, and the opposite sides of the two linear blocks are respectively in close contact with the two ends of the middle part of the cutter.

[0013] The above technical solution allows for easy injection of lubricating oil into the grease fitting, ensuring smooth cutting by both the cutter and the auxiliary blade.

[0014] Both ends of the cutter holder near the attached blade are provided with blade pressing blocks. The cross-sectional shape of the blade pressing blocks is inverted L-shaped, and they are snapped onto both sides of the front end of the cutter. A pad is provided at the front end of the cutter holder. A long straight groove is opened in the middle of the front end of the cutter. The pad passes through the long straight groove and is covered with a blade pressing cover on its outer side. The blade pressing cover is interlocked and pressed by bolts and fastening nuts.

[0015] The above technical solution uses a pressure block to hold down the cutter, which serves to fix and limit it, preventing the cutter from falling off.

[0016] The fixing frame is equipped with an adjusting block. The adjusting block has several horizontal through holes evenly distributed on it. Screws and springs are inserted and installed inside the through holes. The end of the spring away from the screw is equipped with an adjusting screw, and a nut is installed on the outer thread of the adjusting screw.

[0017] Using the above technical solution, rotating the adjusting screw can move the entire device up and down, thereby adjusting the parallelism of the device.

[0018] The adjusting block has round holes at the middle of both ends, and bushings are installed inside the round holes. The top of the fixing frame is covered with a cover plate, and a round through hole is opened in the middle of the cover plate, and a column is inserted into the round through hole.

[0019] In this technical solution, the bushing is fitted onto the outside of the column, and the cover plate is fixedly connected to the top of the fixing frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This utility model's high-speed cutter can sever the edge banding tape. The cutting side of the cutter features a beveled edge, facilitating segmented cutting. The mechanism is designed to swing according to the direction of the edge banding input, tracking and synchronizing at the moment of high-speed cutting to prevent the edge banding from chipping at the tail. The power mechanism uses high-speed absolute value servo control, ensuring accurate positioning and fast response, resulting in more precise cutting and a shorter end length for the edge banding, thus saving material.
