Description

Technical Field

[0001] This utility model relates to the field of wood veneer lathes, and more specifically, to a quick-change mechanism for the cutting blade of a wood veneer lathe. Background Technology

[0002] Wood veneer lathes are key equipment in the wood processing industry, mainly used to process logs into continuous thin wood veneers. After drying, gluing, and assembly, these veneers can be made into plywood, blockboard, and other boards, which are widely used in furniture manufacturing, building decoration, packaging, and other fields. The working principle is that the motor drives the spindle to rotate, which drives the logs fixed on the spindle to rotate synchronously. At the same time, the cutting blades installed on the blade holder continuously cut the rotating logs. By adjusting the relative position of the blade holder and the logs, veneers of different thicknesses can be processed. The core components of the veneer lathe include the spindle transmission system, the blade holder feeding system, the cutting blade adjustment mechanism, and the machine frame. Among them, the sharpness and installation accuracy of the cutting blades directly affect the surface quality and processing efficiency of the veneers.

[0003] Currently, the cutting blades of wood veneer machines are usually fixed with bolts during replacement. This requires the use of wrenches and other tools to remove the bolts one by one, which is not only time-consuming and laborious, but also fails to achieve a fast replacement. Furthermore, frequent replacements can easily lead to problems such as stripped bolt threads or damaged blade holder threads, increasing equipment maintenance costs. In addition, when manually replacing the cutting blade, the operator needs to come into close contact with the rotating parts or sharp blades. If the protective measures are not in place, it is easy to cause hand cuts or accidental start-up of the equipment.

[0004] Therefore, a quick-change mechanism for the cutting blade of a wood veneer lathe is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick-change mechanism for the cutting blade of a wood veneer lathe to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change mechanism for a wood veneer cutting machine, comprising a mounting base, an installation groove on the upper surface of the mounting base, a cutting blade support inside the installation groove, a cutting blade body fixedly mounted on the upper surface of the cutting blade support, a support cover fixedly connected to the bottom surface of the mounting base, a transmission cover fixedly connected to the bottom surface of the support cover, two support members fixedly mounted on the bottom surface of the mounting base, and an electro-hydraulic push rod fixedly mounted on the bottom surface of the transmission cover.

[0007] The telescopic end of the electro-hydraulic actuator is fixedly equipped with a sliding push block. The inside of the support cover is provided with two movable locking blocks. The two movable locking blocks are fixedly connected to fixed locking blocks on their respective sides. The bottom surface of the cutter support is provided with a groove. The sides of the two movable locking blocks that are close to each other are in contact with the two sides of the sliding push block. The inner wall of the groove is provided with two fixed locking slots. The ends of the two fixed locking blocks that are far apart from each other extend into the interior of the two fixed locking slots. The inner walls of the two fixed locking slots are fixedly connected with elastic buffer pads. The sides of the two fixed locking blocks that are far apart from each other are in close contact with the sides of the two elastic buffer pads that are close to each other.

[0008] Preferably, both support members include a support slide fixedly mounted on the bottom surface of the mounting base, a support upright plate slidably connected to the inner wall of each of the two support slides, a mounting base plate fixedly connected to the bottom surface of each of the two support upright plates, two mounting holes on the outer surface of each of the two mounting base plates, a set of threaded holes on one side of each of the two support slides, a threaded groove on one side of each of the two support upright plates, and a fixing screw on one side of each of the two support slides, wherein the outer surface of the fixing screw is adapted to the inner wall of the threaded hole and the inner wall of the threaded groove, respectively.

[0009] Preferably, the inner wall of the support cover is provided with two sets of limiting holes, and two limiting blocks are fixedly connected to the outer surfaces of the two movable blocks. The ends of the two sets of limiting blocks that are far apart from each other extend into the interior of the two sets of limiting holes.

[0010] Preferably, the inner bottom wall of the transmission cover has two sliding holes, and the inner walls of the two sliding holes are slidably connected to sliding plates. The upper surfaces of the two sliding plates are fixedly connected to the outer surface of the sliding push block.

[0011] Preferably, the inner wall of the support cover is fixedly connected with two sets of springs, and the ends of the two sets of springs that are close to each other are respectively fixedly connected to the sides of the two movable blocks that are far apart from each other.

[0012] Preferably, the inner wall of the mounting groove is provided with two sets of positioning grooves, and the outer surface of the cutter support is fixedly connected with two sets of positioning blocks, the bottom ends of the two sets of positioning blocks extending into the interior of the two sets of positioning grooves respectively.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this wood veneer machine uses a quick-change blade mechanism. The blade support at the bottom of the blade body is positioned and inserted into the mounting groove. The sliding push block is driven to rise by an electro-hydraulic push rod, which moves the moving and fixing blocks until the fixing block is embedded in the fixing groove on the bottom surface of the blade support. This locks and fixes the blade support inside the mounting groove, thus quickly fixing the blade body. No wrenches or other tools are needed throughout the process, improving replacement efficiency and solving the problems of time-consuming, labor-intensive, and difficult-to-quickly replacement in traditional methods.

[0015] Compared with existing technologies, this wood veneer lathe's quick-change blade mechanism uses the spring force and the electro-hydraulic push rod to drive the sliding push block downwards, enabling the fixed block to automatically disengage from the fixed slot. Operators can disassemble the blade without close contact with the sharp blade body and rotating parts, reducing the risk of hand injuries, accidental equipment start-up, and other safety accidents. In addition, the cooperation between the positioning block of the blade support and the positioning groove at the mounting slot ensures that the blade edge and the distance between the blade and the spindle are consistent after the blade body is installed, avoiding errors from manual adjustment and thus achieving the effect of quick replacement.

Example

[0026] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

[0027] like Figures 1-5As shown, in a preferred embodiment, both support members 8 include a support slide 801 fixedly mounted on the bottom surface of the mounting base 1. A support upright 802 is slidably connected to the inner wall of each support slide 801. A mounting base plate 806 is fixedly connected to the bottom surface of each support upright 802. Two mounting holes 807 are formed on the outer surface of each mounting base plate 806. A set of threaded holes 805 is formed on one side of each support slide 801. A threaded groove 803 is formed on one side of each support upright 802. A set of threaded holes 805 is formed on one side of each support slide 801. There is a fixing screw 804, and the outer surface of the fixing screw 804 is adapted to the inner wall of the threaded hole 805 and the inner wall of the threaded groove 803 respectively. Furthermore, the setting of two support members 8 allows for flexible adjustment of the overall height. The support plate 802 slides along the support slide 801, which can change the height of the mounting base 1 to adapt to the processing needs of logs of different specifications. After adjustment, the fixing screw 804 passes through the threaded hole 805 and is screwed into the threaded groove 803 to achieve fixation. The mounting hole 807 of the mounting base plate 806 facilitates the fixing of the mechanism to the veneer frame, enhancing the overall stability.

[0028] like Figures 1-5 As shown, in a preferred embodiment, the inner wall of the support cover 5 has two sets of limiting holes 19. Two limiting blocks 20 are fixedly connected to the outer surfaces of the two movable blocks 9. The ends of the two sets of limiting blocks 20 that are far apart from each other extend into the interior of the two sets of limiting holes 19. The inner bottom wall of the transmission cover 6 has two sliding holes 15. Sliding plates 16 are slidably connected to the inner walls of the two sliding holes 15. The upper surfaces of the two sliding plates 16 are fixedly connected to the outer surface of the sliding push block 21. Two sets of springs 14 are fixedly connected to the inner wall of the support cover 5. The ends of the two sets of springs 14 that are close to each other are fixedly connected to the sides of the two movable blocks 9 that are far apart from each other. The inner wall of the mounting groove 2 has two sets of positioning grooves 18. The outer surface of the cutter support 4 is fixedly connected to... There are two sets of positioning blocks 17, the bottom ends of which extend into the interior of two sets of positioning grooves 18. Furthermore, through the cooperation of the limiting hole 19 and the upper limit block 20 of the moving block 9, the moving block 9 can be guided to prevent it from deviating during sliding. Through the cooperation of the sliding hole 15 and the sliding plate 16, the sliding push block 21 is ensured to rise and fall vertically, ensuring the accuracy of the fixed block 12 being embedded in the fixed slot 11. In addition, when the electro-hydraulic push rod 7 retracts, the spring 14 can pull the moving block 9 to reset, which can make the fixed block 12 quickly disengage from the fixed slot 11. Through the cooperation of the positioning groove 18 in the mounting groove 2 and the positioning block 17 on the cutter support 4, the positioning of the cutter support 4 can be quickly changed, reducing adjustment time and improving replacement efficiency.

[0029] The working process of this utility model is as follows:

[0030] When using the quick-change mechanism for the wood veneer, the first step is to install and fix the cutter. Place the cutter support 4 with the cutter body 3 into the mounting groove 2 of the mounting base 1. Then, start the electro-hydraulic push rod 7. Push the sliding push block 21 upward through the telescopic end. This allows the two moving blocks 9 to slide to both sides along the limiting hole 19 in the support cover 5. This will also cause the fixing block 12 to be embedded into the fixing groove 11 on the bottom surface of the cutter support 4 until it is in close contact with the elastic buffer pad 13, thus achieving quick fixation of the cutter body 3 without the need for bolt tightening.

[0031] When disassembling and replacing, the telescopic end of the electro-hydraulic actuator 7 retracts, the sliding push block 21 moves down, the moving block 9 resets under the elastic force of the spring 14, and the fixed block 12 disengages from the fixed slot 11. The operator can then directly remove the cutter support 4 from the mounting slot 2 to complete the replacement, thereby completing the quick replacement of the cutter. This is the working process and working principle of the device.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
