[0001] This utility model relates to a wood chip breaking device for OSB boards, belonging to the technical field of wood chip breaking for OSB boards. Background Technology

[0002] OSB board boasts excellent physical and mechanical properties, a dense structure, high strength, and resistance to deformation, peeling, and warping. It also exhibits good corrosion resistance, insect resistance, deformation resistance, and flame retardancy, and its complete waterproof performance allows it to be permanently exposed to natural environments and humid conditions. Furthermore, OSB board has extremely low formaldehyde emissions, making it a truly green and environmentally friendly product. Its strong nail-holding power and ease of sawing, nailing, drilling, grooving, planing, filing, or sanding make it widely used in furniture making, interior decoration, and building construction, among other fields.

[0003] In the prior art, such as Chinese Patent No. CN 213198024 U, entitled "A Rotary Cut Wood Chip Dispersing Device for OSB Boards," a rotary cutting machine frame is included. A ratchet dispersing mechanism is provided at the inlet and outlet of the rotary cutting machine frame. The ratchet dispersing mechanism includes a rotating shaft with a plurality of ratchet blades evenly spaced on the shaft, and a chip baffle is provided between adjacent ratchet blades. Its beneficial effect is that, when installed on a rotary cutting machine, this invention can quickly disperse the rotary-cut long strips of wood into chips while the machine is cutting the wood, greatly improving the processing efficiency of rotary-cut wood chips for OSB boards. It eliminates the need for manual cutting, significantly saving labor costs and possessing broad market potential.

[0004] However, in the existing technology, when using OSB boards, they are cut by a rotary cutter and then the long strips are quickly broken into wood chips. Generally, when breaking them apart, many very small and unusable wood chips will be produced, which require manual sorting, increasing labor costs and resulting in low efficiency. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems and shortcomings of the existing technology by designing a wood chip breaking device for OSB boards.

[0024] In this embodiment, the workbench 1 is equipped with the device body 2 on top. The workbench 1 is for supporting the operation of the device body 2. The diversion component 3 includes a rotating shaft 31, which passes through both side walls of the device body 2. The rotating shaft 31 serves as the driving component of the device, driving the fixed disk 32 and the screening plate 33 to rotate in the middle of the device body 2. The rotating shaft 31, the fixed disk 32, and the screening plate 33 form a triangular area inside the device body 2. When the main body enters the device body 2, it first contacts the cutting blade 35 and is cut into wood chips. When the wood chips enter this triangular area, those that are too small and do not meet the standards will fall from the diversion hole 34 to the bottom of the device body 2 through the movement of the screening plate 33. The whole process of breaking up and screening qualified and unqualified wood chips is completed, saving manpower.

[0025] Example 2

[0026] like Figure 1-3As shown, the OSB board wood chip breaking device proposed in this utility model, compared with embodiment 1, further includes a rotating shaft 31 extending from both ends of the device body 2, with protective cylinders 4 rotatably sleeved on the outer rings. A support base 5 is fixedly installed on the top of the workbench 1, with a support base 6 fixedly installed on the top of one of the support bases 1-5. The tops of the other support base 1-5 and support base 2-6 are respectively fixed to the bottoms of the two protective cylinders 4. A motor 7 is installed on the top of one of the support bases 1-5, and the output end of the motor 7 is fixed to one end of the rotating shaft 31. An electric telescopic rod 8 is installed on the top of the workbench 1. The output end of the electric telescopic rod 8 passes through the inner wall of the main body 2 of the device and is fixedly connected to a push plate 9. The push plate 9 slides on the bottom inner wall of the main body 2 of the device. A discharge port 10 is opened on the side of the main body 2 away from the push plate 9. A receiving bucket 11 is fixedly installed on one side of the workbench 1. Support legs 12 are provided at the four corners of the bottom of the workbench 1. A feeding slot 13 is provided on the top of the main body 2 of the device. A discharge port 24 is opened on one side of the main body 2 of the device. A baffle 15 is hinged to the top of the discharge port 24 through a hinge.

[0027] In this embodiment, the outer rings of both ends of the rotating shaft 31 extending from the main body 2 of the device are rotatably fitted with protective cylinders 4. The two protective cylinders 4 are respectively fixed on the top of the support base 1 5 and the support base 2 6. The protective cylinders 4 are used to protect the rotating shaft 31 from normal rotation. The support base 1 5 and the support base 2 6 are used to fix the protective cylinders 4. One of the support bases 1 5 has a motor 7 fixed on its top and an electric telescopic rod 8 is provided.

By continuously moving the push plate 9, the debris can be pushed into the collection bucket 11 through the discharge port 10, which is convenient for cleaning. The baffle 15 is provided to prevent the material from splashing out through the discharge port 2 14.

[0028] Working principle: When using the device, first, start the motor 7 and the electric telescopic rod 8. The motor 7 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the fixed disk 32 and the screening plate 33 to rotate inside the main body 2 of the device. Then, put the long strip into the main body 2 of the device through the feed trough 13. Due to the distance between the cutting blade 35 and the inner wall of the main body 2, when the long strip enters the main body 2, it comes into contact with the cutting blade 35 and is directly cut into the required wood chips. The small wood chips will fall onto the rotating shaft 31, the fixed disk 32, and the screen plate 33. During the cutting process, some smaller pieces or debris will fall into the bottom of the main body 2 of the device through the diversion hole 34. The remaining qualified parts will be discharged from the discharge port 14 through the rotation of the screening plate 33. The debris inside the main body 2 will be moved by the output end of the electric telescopic rod 8 to drive the push plate 9. The push plate 9 moves at the bottom of the main body 2. By continuously extending and retracting the push plate 9, the debris can be pushed into the collection bucket 11 through the discharge port 10. Cleaning and screening are convenient and save manpower.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
