Description

Technical Field

[0001] This utility model relates to the field of plywood processing, and in particular to a sawing device for plywood processing. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers and glues the adjacent veneer layers with their fiber directions perpendicular to each other. During the production process, plywood usually requires edge sawing to achieve the predetermined dimensions.

[0003] A search revealed Chinese Patent Publication No. CN212096746U, which discloses a cutting device for processing plywood for furniture decoration. The device includes a base with a cutting groove on its top. A drive motor is fixedly installed inside the base, and a cutting blade is fixedly connected to the output shaft of the drive motor. Two sliding grooves are formed on the top of the base, and sliding rods are fixedly connected between the left and right side walls of the sliding grooves. A sliding seat is slidably connected to the outer side of the sliding rod, and a guide plate is fixedly connected to the top of the sliding seat. Two rulers are fixedly connected to the top of the base, and a bracket is fixedly connected between the left and right sides of the base.

[0004] The aforementioned patent describes a method where plywood is placed on top of a base, and then guided plates on both sides are pushed to clamp the plywood. The guide plates allow the plywood to be cut along a straight line during cutting, preventing misalignment. However, the process of cutting the plywood with a cutting blade requires manual pushing of the plywood, which is not only labor-intensive but also makes it difficult to guarantee cutting accuracy, easily leading to dimensional deviations and increasing the product defect rate. Furthermore, the plywood is prone to displacement under the sawing force during the sawing process, affecting the sawing quality and reducing the overall product quality. Therefore, a sawing device for plywood processing is proposed to solve the above problems. Utility Model Content

The column 2 can guide the displacement direction of the pressure plate 4, enabling the pressure plate 4 to make more precise linear movements, thereby stably pressing the plywood onto the top of the housing 1 through the pressure plate 4, improving the processing accuracy and quality. A control rod 51 is fixedly connected to the top of the pressure plate 4, the control rod 51 passing through and slidably connected to the inner wall of the fixing plate 3, and a spring 52 is sleeved on the surface of the control rod 51, thereby applying a downward elastic force to the pressure plate 4 through the spring 52.

[0032] Reference Figure 1 - Figure 3 The bottom of the top fixing plate 3 of the spring 52 is fixedly connected, and the bottom of the spring 52 is fixedly connected to the top of the pressure plate 4. The top of the outer shell 1 is provided with a control mechanism, and the top of the outer shell 1 is fixedly connected with a positioning frame 25 to calibrate and position the plywood. The interior of the outer shell 1 is provided with a vacuuming mechanism, which includes a vacuum cleaner housing 23. The vacuum cleaner housing 23 is fixedly connected to the inner wall of the outer shell 1. The left side of the vacuum cleaner housing 23 is fixedly connected with a suction head 24. The suction head 24 sucks the wood chips and dust generated during the sawing process into the vacuum cleaner housing 23 to keep the working environment clean.

[0033] Reference Figure 1 , Figure 2The control mechanism includes a fixed block 6, which is fixedly connected to the top of the outer shell 1. A connecting rod 7 is hinged to the surface of the fixed block 6. A connecting rod 8 is hinged to the end of the connecting rod 7 away from the fixed block 6. The lengths of the connecting rod 7 and the connecting rod 8 are equal. Both the connecting rod 7 and the connecting rod 8 are set in an inclined state. A slider 11 with a rectangular cross-section is hinged to the end of the connecting rod 8 away from the connecting rod 7. The slider 11 is slidably connected to the inner wall of the outer shell 1. The connecting rod 7 is hinged to the connecting rod 8 through a pin 9. Grooves 10 are provided on the front and rear sides of the pressure plate 4. The outer wall of the pin 9 fits against the inner wall of the groove 10, so that the pressure plate 4 can be finely adjusted in position while maintaining a pressed state to adapt to plywood of different thicknesses.

[0034] Reference Figure 1 , Figure 2 The control mechanism also includes a screw 12, with a knob on the top of the screw 12. The surface of the knob is provided with anti-slip texture. The screw 12 is threaded to the inner wall of the outer casing 1. A movable plate 13 is rotatably connected to the bottom of the screw 12. The rotation of the screw 12 will drive the movable plate 13, which is rotatably connected to it, to slide on the inner wall of the outer casing 1. The movable plate 13 is slidably connected to the inner wall of the outer casing 1. The sliding direction of the movable plate 13 is up and down. A second spring 14 is fixedly connected to the bottom of the movable plate 13. The bottom of the second spring 14 is fixedly connected to the top of the slider 11. By setting the second spring 14, the movable plate 13 and the slider 11 have a tendency to move away from each other.

[0035] Reference Figure 3 , Figure 4 The housing 1 contains a sawing mechanism, which includes a linear guide rail 15 and a slide plate 16. The linear guide rail 15 is model HGH35-45CA and is fixedly connected to the top of the inner wall of the housing 1. The slide plate 16 is fitted and installed at the bottom of the linear guide rail 15. The sawing mechanism also includes a protective shell 17, the top of which is fixedly connected to the bottom of the slide plate 16. A stepper motor 18 is fixedly connected inside the protective shell 17. The stepper motor 18 can precisely control the rotation angle of its output shaft, facilitating the adjustment of the output shaft's rotation. Speed ​​and rotation angle are adjusted to improve control precision. A horizontally positioned rotating shaft 19 is fixedly connected to the right side of the output shaft of the stepper motor 18. A cutting blade 20 for sawing plywood is fixedly connected to the right side of the rotating shaft 19. A through groove 21 is provided on the left side of the protective shell 17, and a vent hole 22 is provided on the left side of the outer shell 1. The through groove 21 on the left side of the protective shell 17 and the vent hole 22 on the left side of the outer shell 1 cooperate to dissipate the heat generated by the stepper motor 18. The left outer wall of the protective shell 17 is attached to the left side of the inner wall of the outer shell 1.

[0036] Working principle: When in use, pull the control lever 51 upward to make the pressure plate 4 move upward against the elastic force of the spring 52. Then place the plywood at the bottom of the pressure plate 4 on the top of the outer shell 1. Release the control lever 51 so that the pressure plate 4 presses the plywood downward under the elastic force of the spring 52 to complete the initial fixation. Then, by rotating the screw 12, since the screw 12 is threaded to the inner wall of the outer shell 1, the rotation of the screw 12 will drive the moving plate 13 to slide up and down on the inner wall of the outer shell 1. When the moving plate 13 moves downward, it compresses the second spring 14. The elastic force of the second spring 14 acts on the slider 11, pushing the slider 11 to slide downward. The movement of the slider 11 will cause the connecting rod 7 and the second connecting rod 8 to rotate around their respective hinge points. Since the outer wall of the pin 9 is in contact with the inner wall of the groove 10 on both sides of the pressure plate 4, the rotation of the second connecting rod 8 will cause the pin 9 to move in the groove 10, thereby causing the pressure plate 4 to overcome the elastic force of the first spring 52 and slide downward along the column 2, further increasing the clamping force on the plywood, thereby increasing the friction between the plywood and the top of the outer shell 1, ensuring that the plywood will not be displaced during the sawing process, thereby improving the sawing accuracy and the quality of the finished product.

[0037] After the plywood is fixed, the stepper motor 18 is started. The output shaft of the stepper motor 18 drives the rotating shaft 19 to rotate, which in turn causes the cutting blade 20 to rotate. At the same time, the slide plate 16 can move linearly along the linear guide rail 15 under the guidance of the linear guide rail 15, which drives the protective shell 17, the stepper motor 18 and the cutting blade 20 to move synchronously, so as to perform automatic sawing operation on the plywood, reduce manual operation steps and improve work efficiency.

[0038] During the cutting process, the vacuum cleaner is activated, and the cutting debris generated is sucked into the vacuum cleaner housing 23 through the suction head 24 for collection and treatment, keeping the working environment clean and preventing wood chips from flying and causing harm to the operator's health and pollution to the work area.

[0039] After sawing is completed, the stepper motor 18 is stopped first, the cutting blade 20 stops rotating, and the cutting blade 20 returns to its initial position through the cooperation of the linear guide rail 15 and the slide plate 16. Then, by pulling the control lever 51 upward, the pressure plate 4 overcomes the elastic force of the spring 52 and slides upward along the column 2, thereby releasing the pressure on the plywood, and the sawn plywood can be taken out.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
