Description

Technical Field

[0001] This utility model relates to the field of plywood cutting technology, specifically a cutting device for water-resistant and weather-resistant plywood. Background Technology

[0002] Water-resistant and weather-resistant plywood is made of multiple layers of veneer bonded together with adhesives. It features stable structure, high strength, and water and weather resistance. During the cutting process, it is necessary to ensure that the cut surface is flat and the dimensions are accurate, while avoiding damage to the board. Therefore, the cutting device needs to have high precision, high stability and good cutting performance.

[0003] However, when the cutting blade penetrates deep into the wood and stops cutting due to a power outage, the blade can easily get stuck in the board due to the elasticity and friction of the plywood.

[0004] Existing processing methods use tools such as pliers or hammers to pull out or knock the plywood, which is not only inefficient but also easily damages the plywood and the cutting head. This damage not only affects the usability of the plywood but may also cause the cutting head to fail prematurely, increasing production costs.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] The purpose of this invention is to provide a cutting device for water-resistant and weather-resistant plywood to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a cutting device for water-resistant and weather-resistant plywood, including a cutting blade, wherein a reversing mechanism is fixedly installed on the side wall of the cutting blade;

[0008] The reversing mechanism includes an inner ratchet fixedly mounted on the side wall of the cutting blade. A turntable is provided on the inner wall of the inner ratchet. A pawl is rotatably mounted on the side wall of the turntable. A spring abuts against the inner wall of the pawl. The end of the spring is fixed to the side wall of the turntable. A rotating column is fixedly mounted on the side wall of the turntable. An actuating column is sleeved on the outer wall of the rotating column.

[0009] Furthermore, a groove is provided on the surface of the rotating column, and a sliding column is slidably installed on the inner wall of the groove, and the sliding column is fixedly installed on the inner wall of the pressing column.

[0010] Furthermore, the turntable is rotatably mounted on the side wall of the cutting blade, and a groove is provided on the side end of the turntable, in which a pawl and a spring are fixedly installed.

[0011] Furthermore, a retaining ring is threadedly installed on the side wall of the cutting blade away from the inner ratchet, and a bolt is threadedly connected to the inner wall of the retaining ring. The retaining ring is fixedly installed on the drive end of the motor on the side wall away from the cutting blade.

[0012] Furthermore, a fixing plate is fixedly installed at the end of the motor away from the fixing ring, and a cutting table is fixedly installed on the top of the fixing plate.

[0013] Furthermore, a cutting groove is provided on the top of the cutting table, and the inner wall of the cutting groove is in contact with the outer wall of the cutting blade.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: when the cutting blade penetrates deep into the plywood and stops cutting due to a power outage, the operator only needs to press the push rod to quickly reverse the cutting blade through the reversing mechanism, thereby easily freeing it from the constraints of the board. This avoids the direct physical impact on the plywood and the cutting head in traditional methods, thus reducing damage to the board and wear on the cutting head. This not only preserves the usability of the plywood but also extends the service life of the cutting head and reduces production costs. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a cutting device for water-resistant and weather-resistant plywood, including a cutting blade 3, and a reversing mechanism is fixedly installed on the side wall of the cutting blade 3;

[0023] The reversing mechanism includes an inner ratchet 9 fixedly mounted on the side wall of the cutting blade 3. A turntable 10 is provided on the inner wall of the inner ratchet 9. A pawl 11 is rotatably mounted on the side wall of the turntable 10. A spring piece 12 abuts against the inner wall of the pawl 11. The end of the spring piece 12 is fixed on the side wall of the turntable 10. A rotating column 13 is fixedly mounted on the side wall of the turntable 10. A pressing column 4 is sleeved on the outer wall of the rotating column 13.

[0024] It should be noted that when the operator presses the push post 4, the push post 4 slides along the outer wall of the rotating post 13, causing the turntable 10 to start rotating around its axis. Under the elastic force of the spring piece 12, the pawl 11 engages in the tooth groove of the inner ratchet 9, realizing the connection between the turntable 10 and the inner ratchet 9, which will drive the cutting blade 3 to rotate in the opposite direction.

[0025] Furthermore, the reversing mechanism allows the cutting blade 3 to rotate in the opposite direction, making it easy to detach from the inner wall of the plywood.

[0026] Please see Figure 3 This utility model provides a technical solution: a cutting device for water-resistant and weather-resistant plywood, including a rotating column 13 with a groove 15 on its surface, a sliding column 14 slidably installed on the inner wall of the groove 15, and the sliding column 14 fixedly installed on the inner wall of the pressing column 4.

[0027] It should be noted that: through the cooperation of the slide groove 15 and the slide column 14, the operator can more easily press the push column 4 to reverse the cutting blade 3.

[0028] Please see Figure 2 This utility model provides a technical solution: a cutting device for water-resistant and weather-resistant plywood, including a turntable 10 rotatably mounted on the side wall of the cutting blade 3, and a groove 16 is provided on the side end of the turntable 10, and a pawl 11 and a spring piece 12 are fixedly installed inside the groove 16.

[0029] It should be noted that: under the action of the spring piece 12, the pawl 11 can flexibly engage or disengage from the tooth groove of the inner ratchet 9, thereby achieving the reversal of the cutting blade 3;

[0030] Furthermore, by creating a groove 16 on the side of the turntable 10 to fix and install the pawl 11 and the spring 12, the entire reversing mechanism becomes more compact and occupies less space.

[0031] Please see Figure 4This utility model provides a technical solution: a cutting device for water-resistant and weather-resistant plywood, including a fixing ring 5 threadedly installed on the side wall of the cutting blade 3 away from the inner ratchet 9, a bolt 6 threadedly connected to the inner wall of the fixing ring 5, and the fixing ring 5 fixedly installed on the drive end of the motor 7 on the side wall away from the cutting blade 3.

[0032] It should be noted that the retaining ring 5 serves as a bridge connecting the cutting blade 3 and the motor 7. Through a threaded connection, the retaining ring 5 can be tightly fixed to the side wall of the cutting blade 3, ensuring that the cutting blade 3 will not loosen or fall off when rotating at high speed.

[0033] Please see Figure 4 This utility model provides a technical solution: a cutting device for water-resistant and weather-resistant plywood, including a motor 7 with a fixed plate 8 fixedly installed at the end away from the fixed ring 5, and a cutting table 1 fixedly installed on the top of the fixed plate 8.

[0034] It should be noted that the connection between the motor 7 and the cutting table 1 via the fixing plate 8 forms a stable support structure, which helps to reduce the vibration and noise generated by the motor 7 during operation and improves the stability and reliability of the cutting device.

[0035] Please see Figure 5 This utility model provides a technical solution: a cutting device for water-resistant and weather-resistant plywood, including a cutting table 1 with a cutting groove 2 on the top, the inner wall of the cutting groove 2 being in contact with the outer wall of the cutting blade 3.

[0036] It should be noted that during the cutting process, the friction between the cutting blade 3 and the material to be cut will generate dust. By making the inner wall of the cutting groove 2 and the outer wall of the cutting blade 3 fit tightly together, the dust can be effectively prevented from entering the interior of the cutting table 1, thus keeping the interior of the cutting table 1 clean.

[0037] Working principle: When the power is off and the cutting blade 3 is stuck deep in the plywood, press the actuating column 4. The sliding column 14 on the inner wall of the actuating column 4 slides along the sliding groove 15 on the surface of the rotating column 13 and makes the rotating column 13 rotate, which drives the turntable 10 to start rotating. The pawl 11 on the side of the turntable 10 moves with the rotation of the turntable 10. The pawl 11 is kept in the locked state under the elastic force of the spring piece 12 to prevent the turntable 10 and the inner ratchet 9 from rotating in the opposite direction. Since the inner ratchet 9 is fixedly connected to the cutting blade 3, when the turntable 10 rotates by locking the pawl 11 with the inner ratchet 9, it will drive the cutting blade 3 to rotate in the opposite direction.
