Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically a log rotary cutting machine. Background Technology

[0002] A log veneer lathe is used to process round logs of a certain length and diameter into continuous straight veneers for the production of plywood, veneer panels, and other engineered wood products. Log veneer lathes can be classified into those with a chuck and those without.

[0003] A search revealed that the existing technology, specifically the authorized patent with publication number CN220113540U, discloses a log veneer machine. This machine facilitates the detection of the coaxiality between the log to be veneered and the two sets of clamping shafts, ensuring cutting accuracy during veneer cutting, preventing excessive cutting depth of the veneer blade, and improving reliability during use. It includes a base plate, a veneer blade, and a front-to-back moving device. The veneer blade is mounted on the base plate via the front-to-back moving device, which moves the veneer blade in the front-to-back direction. It also includes two sets of support plates, two sets of clamping shafts, multiple sets of pointed cones, a servo motor, a coaxial detection device, and two sets of left-to-right moving devices. The two sets of support plates are respectively mounted on the left and right sides of the base plate via the two sets of left-to-right moving devices, which move the support plates in the left-to-right direction.

[0004] The above-mentioned technical solution still has the following shortcomings in use: the device can only detect the coaxiality of the log and the clamping shaft, but it cannot quickly place the log and the clamping shaft to maintain coaxiality as much as possible. On the contrary, the detection process reduces the working efficiency of the veneer cutting process, making it less practical. In response, we propose a log veneer cutting machine to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a log veneer cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a log veneer cutting machine, comprising: A bottom mounting base has a fixed support plate fixedly mounted on its top wall. A sliding seat is fixedly welded to the top wall of the bottom mounting base, and a movable support plate is slidably connected to the sliding seat. Both the fixed support plate and the movable support plate have rotatably mounted retaining pins. Multiple retaining cones are fixedly welded to the opposite side walls of the two retaining pins. A drive motor is fixedly mounted on the fixed support plate, and the output end of the drive motor is connected to the corresponding retaining pin. A through slot is formed on the fixed support plate. A drive box is fixedly mounted on the end of the bottom mounting base near the fixed support plate, and the top of the drive box is fixedly welded... The drive housing has a guide rod, and a servo motor is fixedly installed inside the drive housing. The output end of the servo motor is connected to a bidirectional lead screw, and two moving rods are threaded onto the bidirectional lead screw. The two moving rods are slidably connected to the guide rod through through holes. The two moving rods are symmetrically arranged on the upper and lower sides of the bearing shaft. The lower moving rod is slidably connected to a through groove. An arc-shaped placement plate is fixedly installed on the top wall of the lower moving rod, and a clamping plate is fixedly welded to the bottom wall of the upper moving rod. A controller is fixedly installed on one side wall of the drive housing. Both the drive motor and the servo motor are electrically connected to the controller through wires.

[0007] Preferably, an L-shaped mounting bracket is fixedly welded to one end of the bottom mounting base near the movable support plate, and a first hydraulic rod is fixedly mounted on the L-shaped mounting bracket. The output end of the first hydraulic rod is fixedly mounted on the movable support plate, and the first hydraulic rod is electrically connected to the controller via a wire.

[0008] Preferably, a rotary cutter is provided on the front side of the two card shafts, a mounting block is fixedly installed on the rotary cutter, a second hydraulic rod is fixedly installed on the mounting block, and the second hydraulic rod is fixedly installed on the mounting device of the external device.

[0009] Preferably, a touch sensor is fixedly installed on the bottom wall of the card plate, and the touch sensor is electrically connected to the controller via a wire.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In use, the log to be rotary-cut is placed on an arc-shaped placement plate. The controller controls the servo motor to drive the bidirectional lead screw to rotate forward, causing the two moving rods to move towards each other on the guide rod, moving the log upward. When the clamping plate moves to the top side of the log, the touch sensor contacts the log and transmits a signal to the controller. The controller then shuts off the servo motor. At this point, the log is moved to a position that is as coaxial as possible with the clamping shaft, improving the coaxiality of the log with the clamping shaft during placement. The placement operation is also convenient, improving work efficiency. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 This utility model provides a technical solution: a log veneer cutting machine, comprising: A bottom mounting base 1 has a fixed support plate 2 fixedly mounted on its top wall. A sliding seat 3 is fixedly welded to the top wall of the bottom mounting base 1. A movable support plate 4 is slidably connected to the sliding seat 3. A retaining shaft 5 is rotatably mounted on both the fixed support plate 2 and the movable support plate 4. Multiple retaining cones 6 are fixedly welded to the opposite side walls of the two retaining shafts 5. A drive motor 7 is fixedly mounted on the fixed support plate 2. The output end of the drive motor 7 is connected to the corresponding retaining shaft 5. A through slot 8 is provided on the fixed support plate 2. A drive box 9 is fixedly mounted on one end of the bottom mounting base 1 near the fixed support plate 2. A guide rod 10 is fixedly welded to the top of the drive box 9. A servo motor 11 is fixedly installed in the inner cavity of the drive box 9. The output end of the servo motor 11 is connected to a bidirectional lead screw 12. Two moving rods 13 are threadedly connected to the bidirectional lead screw 12. The two moving rods 13 are slidably connected to the guide rod 10 through the through holes. The two moving rods 13 are symmetrically arranged on the upper and lower sides of the clamping shaft 5. The lower moving rod 13 is slidably connected in the through groove 8. An arc-shaped placement plate 14 is fixedly installed on the top wall of the lower moving rod 13. A clamping plate 15 is fixedly welded to the bottom wall of the upper moving rod 13. A controller 21 is fixedly installed on one side wall of the drive box 9. The drive motor 7 and the servo motor 11 are both electrically connected to the controller 21 through wires.

[0015] An L-shaped mounting bracket 16 is fixedly welded to one end of the bottom mounting base 1 near the movable support plate 4. A first hydraulic rod 17 is fixedly mounted on the L-shaped mounting bracket 16. The output end of the first hydraulic rod 17 is fixedly mounted on the movable support plate 4. The first hydraulic rod 17 is electrically connected to the controller 21 through a wire. The first hydraulic rod 17 is used to adjust the movable support plate 4, so as to push the cone 6 of the locking shaft 5 on the movable support plate 4 into the end of the round wood.

[0016] Two rotary cutters 18 are provided on the front side of the two cladding shafts 5. A mounting block 19 is fixedly installed on the rotary cutter 18. A second hydraulic rod 20 is fixedly installed on the mounting block 19. The second hydraulic rod 20 is fixedly installed on the external mounting device and is used to drive the rotary cutter 18 to move.

[0017] A touch sensor 22 is fixedly installed on the bottom wall of the card plate 15. The touch sensor 22 is electrically connected to the controller 21 through a wire. When the card plate 15 contacts the log, the touch sensor 22 can transmit a signal to the controller 21. The controller 21 can turn off the servo motor 11 so that the arc-shaped placement plate 14 and the card plate 15 can keep the log as coaxial as possible with the card shaft 5.

[0018] Working principle: In use, the log to be rotary cut is placed on the arc-shaped placement plate 14. The controller 21 controls the servo motor 11 to drive the bidirectional lead screw 12 to rotate in the forward direction, so that the two moving rods 13 move towards each other on the guide rod 10, moving the log upward. When the clamping plate 15 moves to contact the top side of the log, the touch sensor 22 contacts the log and transmits a signal to the controller 21. The controller 21 shuts off the servo motor 11. At this time, the log will be moved to a position as coaxial as possible with the clamping shaft 5. Then, the first hydraulic rod 17 is controlled to push the movable support plate 4 to move, so that the clamping cone 6 on the clamping shaft 5 is inserted into the end of the log. Then, the controller 21 controls the servo motor 11 to rotate in the reverse direction, so that the arc-shaped placement plate 14 and the clamping plate 15 are reset. After that, the drive motor 7 drives the log to rotate, and the second hydraulic rod 20 pushes the rotary cutter 18 to move and rotary cut the log.
