[0001] This utility model belongs to the field of wood cutting technology, and in particular relates to a large saw fixing device to prevent wood from shifting. Background Technology

[0002] Timber is an important raw material, widely used in construction, home decoration and many other fields. In the timber processing industry, timber of different shapes and sizes is often needed. Therefore, timber raw materials are cut according to the required size. Commonly cut timber shapes include cylindrical timber.

[0003] Currently, wood cutting is generally done manually by pushing the wood onto the saw blade of the cutting machine for cutting. The wood needs to be held by hand during the cutting process. However, this cutting method has many problems. First, holding the wood by hand is not stable enough, and the wood is prone to shifting during the cutting process, resulting in a crooked cut. On the other hand, holding the wood by hand is dangerous, as the wood is prone to springing back after being cut and injuring the worker. Utility Model Content

[0011] Compared with the prior art, the embodiments of this application have the following main advantages:

[0012] By setting up a limiting platform, the wood is placed in the trapezoidal groove of the limiting platform. At the same time, the chainsaw exerts pressure on the wood when it presses down. At this time, the wood is fixed at three points, so it will not shift, thus ensuring the precise cutting of the wood. By setting up a pressure plate, when the chainsaw descends, the pressure plate first contacts the surface of the wood, and at the same time, the pressure of the counterweight makes the wood tightly pressed down, thus making the wood more stable during cutting. By setting up two sets of pressure plates, both ends of the wood can be pressed together after cutting, thus preventing the wood from popping out after cutting. By setting up a motor-driven conveyor roller to transport the wood, it further saves manpower and improves the safety of the cutting work. Attached Figure Description

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a large saw fixing device to prevent timber displacement, such as... Figure 1-4 As shown, the system includes an operating platform 1 and a drive box 3. A gantry frame 2 is mounted on the upper end of the operating platform 1. A guide plate 4 is mounted on the side of the drive box 3. A chainsaw 5 is slidably mounted on the edge of the guide plate 4. The chainsaw 5 is connected to the drive gear in the drive box 3. Slide grooves are provided on both the left and right side walls of the gantry frame 2, and limit blocks 6 are slidably embedded in the slide grooves. The guide plate 4 is mounted on the side of the limit blocks 6. An electric cylinder 7 is mounted on the upper bottom of the operating platform 1. A support plate 8 is mounted on the top of the output shaft of the electric cylinder 7. Support frames 9 are mounted on the top of both ends of the support plate 8. The support frames 9 extend through the operating platform 1 into the slide grooves of the gantry frame 2 and are connected to the limit blocks 6. The bottom of the device is connected to the limit platform 1. The upper end of the operating platform 1 is equipped with a limit platform 10. The upper surface of the limit platform 10 is provided with a trapezoidal groove. The surface of the limit platform 10 is provided with a cutting groove corresponding to the position of the chainsaw 5. When the device is in use, the wood to be cut can be placed on the limit platform 10. Then the drive box 3 is started to drive the chainsaw 5 to drive. At the same time, the electric cylinder 7 is started to slowly lower the chainsaw 5 to cut the wood. By setting the limit platform 10, the wood is placed in the trapezoidal groove of the limit platform 10. At the same time, the chainsaw 5 will exert pressure on the wood when it is pressed down. At this time, the wood is fixed at three points, so it will not shift, thus ensuring the precise cutting of the wood.

[0021] The guide plate 4 is located at the center of the limiting block 6. Connecting plates 11 are installed on both the left and right sides of the limiting block 6. Fixed frames 12 are installed at the ends of the two sets of connecting plates 11 that are far apart from each other. A counterweight 13 is slidably embedded inside the fixed frame 12. A connecting rod 14 is installed at the lower end of the counterweight 13. The connecting rod 14 is slidably installed and a pressure plate 15 is installed at the bottom. The pressure plate 15 is located directly above the limiting platform 10. By setting the pressure plate 15, when the chainsaw 5 descends, the pressure plate 15 first contacts the surface of the wood, and at the same time, the wood is tightly pressed down under the pressure of the counterweight 13, so that the wood is more stable when cutting. By setting two sets of pressure plates 15, both ends of the wood after cutting can be pressed together, thereby preventing the wood from popping out after cutting.

[0022] The lower surface of the pressure plate 15 is serrated to prevent the wood from rotating during the cutting process.

[0023] Conveying rollers 16 are symmetrically installed in the trapezoidal groove of the limiting platform 10. The conveying rollers 16 are equidistantly distributed along the horizontal direction of the limiting platform 10. By setting the conveying rollers 16, the conveying rollers 16 can rotate on the side wall of the limiting platform 10. This setting makes it easier and less strenuous to push the wood for cutting.

[0024] A motor 17 is installed on the side of the limiting table 10. The output shaft of the motor 17 is connected to the central shaft of one of the conveyor rollers 16. The conveyor rollers 16 are connected by a belt 18. By setting up the motor 17 and the belt 18, the automatic propulsion of wood can be achieved by driving the conveyor rollers 16 to rotate through the motor 17, which further saves manpower and improves the safety of cutting work.

[0025] The limiting platform 10 has two sets of trapezoidal grooves that are symmetrically distributed. By having two sets of trapezoidal grooves, two pieces of wood can be cut at the same time, thereby improving the cutting efficiency of the device.
