Description

Technical Field

[0001] This utility model relates to the field of planing machine technology, and in particular to an automatic blade gap adjustment device for a vertical planing machine. Background Technology

[0002] A vertical planer is a type of planer that performs planing on a vertical plane. The blank (timber) is secured to a vertical worktable, which drives the blank to reciprocate up and down in the vertical plane to complete the main cutting motion. When the blank is in the working stroke, the planer blades on the blade holder plane the blank to obtain veneer. During the idle stroke, the blade holder makes a feed motion in the horizontal direction, feeding one layer of veneer each time. A pressure gauge is installed behind the planer blades to hold the part of the blank to be planed, ensuring that the planed veneer does not tear or shear.

[0003] The blade gap is the horizontal gap between the planer blade and the pressure gauge. Currently, the blade gap is adjusted using a mechanical screw. The accuracy of the blade gap adjustment is one of the main factors determining the precision of veneer planing. The blade gap adjustment mainly depends on the operator's proficiency in the machine. This not only requires a high level of operator skill but is also cumbersome and not conducive to improving production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic blade gap adjustment device for a vertical planer to solve the problems existing in the prior art, thereby improving the blade gap adjustment accuracy, increasing production efficiency, and reducing labor costs.

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides an automatic blade gap adjustment device for a vertical planer, including a blade gap adjustment servo motor, a blade gap adjustment wheel, a blade gap adjustment screw, and a blade gap locking cylinder. The blade gap adjustment servo motor is connected to the blade gap adjustment wheel via a synchronous belt. The blade gap adjustment wheel is sleeved on the blade gap adjustment screw and threadedly connected to it. The front end of the blade gap adjustment screw is threadedly fixed to a pressure gauge frame for mounting a pressure gauge and locked with a nut. A limiting seat is provided opposite to the rear end of the blade gap adjustment screw. The limiting seat is located on the top of a blade plate frame for mounting planer blades and is opposite to the blade gap adjustment wheel. The cylinder body of the blade gap locking cylinder is fixed to the blade plate frame, and the piston rod end of the cylinder is fixed to the pressure gauge frame. The cylinder pushes the pressure gauge frame back and forth through the piston rod.

[0006] Preferably, the tool gap adjustment servo motor is mounted on the rear end of the pressure gauge frame via a motor bracket.

[0007] Preferably, a main drive wheel is provided on the power output shaft of the tool gap adjustment servo motor, and the main drive wheel is connected to the tool gap adjustment wheel through the synchronous belt.

[0008] Preferably, the end of the piston rod of the gap locking cylinder is connected to one side of the pressure gauge frame via a connecting bracket.

[0009] Preferably, the cylinder body of the blade gap locking cylinder is mounted on one side of the blade holder via a mounting bracket.

[0010] Preferably, it also includes a ruler frame locking cylinder, which is disposed on the top of the ruler frame and is used to vertically lock the ruler frame.

[0011] The present invention achieves the following technical advantages over the prior art: Improved precision and stability: With mechanical screw structures, operators need to manually adjust the screw with a wrench. Even experienced technicians cannot avoid errors of ±0.05mm caused by uneven force and visual deviation, which directly affects the consistency of wood veneer thickness. The scrap rate of high-end decorative materials often reaches 3%-5%. By using a servo motor drive, in conjunction with the blade gap adjustment wheel and blade gap adjustment screw to adjust the blade gap, the blade gap adjustment error is stabilized within ±0.005mm, the consistency of wood veneer thickness is improved by 80%, and the pass rate of high-end custom materials climbs from 92% to 99.5%.

[0012] Improved production efficiency: With a mechanical screw structure, changing wood species or adjusting thickness parameters requires machine downtime, taking approximately 15-20 minutes per operation. In multi-batch, small-volume production scenarios, the equipment's effective utilization rate is significantly reduced. By adopting a PLC system to control servo motor adjustments, changeover adjustment time is drastically reduced from 15 minutes to 30 seconds, increasing the equipment's effective operating rate by 25%.

[0013] Labor costs: Previously, training a skilled worker capable of precise operation required 6-12 months, and staff turnover could cause fluctuations in production stability. Now, the training cycle for operators has been shortened to 1 week, reducing labor costs by 40%. Attached Figure Description

[0016] 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.

[0017] The purpose of this invention is to provide an automatic blade gap adjustment device for a vertical planer to solve the problems existing in the prior art.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The automatic blade gap adjustment device 101 of the vertical planer in this embodiment, such as Figures 1-4 As shown, the device includes a tool gap adjustment servo motor 1, a tool gap adjustment wheel 2, a tool gap adjustment screw 3, and a tool gap locking cylinder 4. The tool gap adjustment servo motor 1 is connected to the tool gap adjustment wheel 2 via a synchronous belt 5. The tool gap adjustment wheel 2 is sleeved on the tool gap adjustment screw 3 and threadedly connected to the tool gap adjustment screw 3. The front end of the tool gap adjustment screw 3 is threadedly fixed to a pressure gauge frame 9 for mounting a pressure gauge 8 and locked with a nut. A limiting seat 11 is provided opposite to the rear end of the tool gap adjustment screw 3. The limiting seat 11 is located on the top of a blade plate frame 7 for mounting a planer blade 6 and is opposite to the tool gap adjustment wheel 2. The cylinder body end of the tool gap locking cylinder 4 is fixed to the blade plate frame 7, and the piston rod end of the tool gap locking cylinder 4 is fixed to the pressure gauge frame 9. The tool gap locking cylinder 4 pushes the pressure gauge frame 9 to move back and forth through the piston rod.

[0020] In this specific embodiment, the tool gap adjustment servo motor 1 is mounted on the rear end of the pressure gauge frame 9 via a motor bracket. A main drive wheel 10 is provided on the power output shaft of the tool gap adjustment servo motor 1. The main drive wheel 10 is connected to the tool gap adjustment wheel 2 via the synchronous belt 5. The power of the tool gap adjustment servo motor 1 is transmitted to the tool gap adjustment wheel 2 through the main drive wheel 10 and the synchronous belt 5, causing the tool gap adjustment wheel 2 to rotate. Since the tool gap adjustment screw is locked on the pressure gauge frame 9, the rotational motion of the tool gap adjustment wheel 2 is converted into axial linear motion. The axial position of the tool gap adjustment wheel 2 on the tool gap adjustment screw determines the distance between it and the limit seat 11. When the tool gap locking cylinder 4 pushes the pressure gauge frame 9 toward the limit seat 11, the distance between the tool gap adjustment wheel 2 and the limit seat 11 determines the distance it can move. This distance is the horizontal gap (tool gap) between the pressure gauge 8 and the planer 6. In other words, adjusting the axial position of the tool gap adjustment wheel 2 on the tool gap adjustment screw determines the size of the tool gap, thus realizing the adjustment of the tool gap.

[0021] In this specific embodiment, the end of the piston rod of the gap locking cylinder 4 is connected to one side of the pressure gauge frame 9 via a connecting bracket 12. The cylinder body of the gap locking cylinder is mounted to one side of the blade plate frame 7 via a mounting bracket 13. During operation, the piston rod of the gap locking cylinder 4 pushes the pressure gauge frame 9 back and forth via the connecting bracket 12.

[0022] In this specific embodiment, a pressure gauge frame locking cylinder 14 is also included. The pressure gauge frame locking cylinder 14 is disposed on the top of the pressure gauge frame 9 and is used to vertically lock the pressure gauge frame 9. The cylinder body of the pressure gauge frame locking cylinder 14 is fixed to the top of the pressure gauge frame 9, and the piston rod of the pressure gauge frame locking cylinder 14 is connected to the blade holder 7 at the bottom of the pressure gauge frame 9. The vertical extension and retraction of the piston rod realizes the vertical pressing between the pressure gauge frame 9 and the blade holder 7, thereby locking the pressure gauge 8 and the planer blade 6.

[0023] The working principle of the automatic blade gap adjustment device 101 for the vertical planer of this utility model is as follows: The tool gap adjusting wheel 2 is driven by the tool gap adjusting servo motor 1 to rotate on the tool gap adjusting screw, generating axial linear motion. This, in conjunction with the tool gap locking cylinder 4, changes the tool gap of the pressure gauge frame 9 (pressure gauge 8). The tool gap is the horizontal clearance between the planer blade 6 and the pressure gauge 8. The tool gap adjustment is controlled by a PLC program. First, the desired tool gap value is input on the touchscreen. Then, the program controls the pressure gauge frame locking cylinder 14 to be in a relaxed state. Next, the tool gap locking cylinder 4 pushes the pressure gauge frame 9 (pressure gauge 8) forward. At this time, the tool gap adjusting servo motor 1, via the synchronous belt 5, moves the tool gap adjusting wheel 2 to the set value. Then, the tool gap locking cylinder 4 pushes the pressure gauge frame 9 (pressure gauge 8) backward until the tool gap adjusting wheel 2 contacts the limit seat 11. Finally, the pressure gauge frame locking cylinder 14 locks the pressure gauge frame 9 (pressure gauge 8). This completes the change of the tool gap value.

[0024] It should be noted that the vertical planer involved in this utility model is an existing device, and the blade holder 7, pressure ruler holder 9 and other structures involved are existing structures. Their working principles and structures will not be described in detail.

[0025] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
