A protective chipper fly knife pressure plate

Abstract

This utility model discloses a protective blade pressure plate for a chipper, belonging to the field of chipper technology. It includes a blade roller, multiple blades, and a pressure plate. The pressure plate is equipped with a protective mechanism, which includes a protective plate and a baffle. The protective plate has a mounting groove, and the baffle is movably connected within the mounting groove. A second round rod is symmetrically fixed within the mounting groove, and a second spring is sleeved on the second round rod. Through the coordinated use of these devices, the blades are protected. During use, moving the rotating column upwards and rotating it releases the restriction on the protective plate, allowing the protective plate to move to the surface of the blades. Then, when the baffle on the protective plate moves to the end of the blade, the stretched second spring returns to its original position, pushing the baffle out from the mounting groove on the protective plate, thus protecting the blade edge and preventing the exposed blade from colliding with external objects due to lack of protection, which would affect the lifespan of the blade.

Description

Technical Field

[0001] This utility model relates to the field of chipper technology, specifically a chipper blade pressure plate with protective function. Background Technology

[0002] The fly knife clamping plate is mainly used in the clamping plate type blade mounting structure of chippers. It is a clamping plate that is used to clamp and secure a set of fly knife blades. The clamping plate is tightened by bolts to apply clamping pressure and secure the fly knife blades.

[0003] An investigation revealed that a Chinese utility model patent discloses a protective chipper blade pressure plate (publication number: CN219819874U), which includes a pressure plate body and fixing bolts. A protective component is provided on the top of the pressure plate body. The protective component includes two fixing blocks fixedly installed on the top of the pressure plate body. Each of the two fixing blocks has a fixing groove inside. Rotating rods are rotatably connected between the front and rear side walls of the inner cavities of the two fixing grooves. Gears are fixedly installed on the outer sides of the two rotating rods.

[0004] Although the aforementioned patent can limit the movement of the fixing bolts after tightening by setting protective components, preventing the previous fixing bolt from loosening and rotating when tightening another fixing bolt, thus avoiding safety accidents during the use of the flying knife pressure plate, when the chipper is in operation, the flying knife needs to be mounted on the cutter roller with the cutting edge extending a certain distance beyond the surface of the cutter roller to achieve the cutting function. However, during transportation, handling, or loading and unloading, the exposed cutting edge is easily collided with external objects due to the lack of protection, resulting in the cutting edge curling, cracking, or even overall deformation, which seriously affects the service life and cutting accuracy of the tool.

[0005] Therefore, this utility model provides a protective blade pressure plate for a chipper to solve the above problems. Utility Model Content

[0025] 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.

[0026] This utility model provides a pressure plate, such as Figures 1-6As shown, the technical solution includes a cutter roller 1, multiple flying knives 2, and a pressure plate 3. The pressure plate 3 is equipped with a protective mechanism, which includes a protective plate 4 and a baffle 6. The protective plate 4 has an installation groove, and the baffle 6 is movably connected in the installation groove. A second round rod 13 is symmetrically fixed in the installation groove, and a second spring 14 is sleeved on the second round rod 13. The two ends of the second spring 14 are fixedly connected to the baffle 6 and the inner wall of the installation groove, respectively. By setting the protective plate 4 and the baffle 6 in the protective mechanism, the flying knives 2 are protected. When the baffle 6 on the protective plate 4 moves to the end of the flying knife 2, the second spring 14 in the stretched state returns to its original position and pushes the baffle 6 out of the installation groove on the protective plate 4, thus protecting the blade of the flying knife 2 and preventing the exposed blade from colliding with external objects due to lack of protection. A U-shaped block 5 is symmetrically provided on the protective plate 4, and a positioning mechanism is provided between the U-shaped block 5 and the pressure plate 3. The positioning mechanism includes a rotating column 8 and two third springs 18.

[0027] The pressure plate 3 has a connecting groove, the protective plate 4 is slidably connected in the connecting groove, the connecting block 10 is symmetrically fixed in the connecting groove, the connecting block 10 is fixedly connected to the inner wall of the connecting groove, and the first round rod 11 slides through the protective plate 4. The first round rod 11 is sleeved on the first round rod 11, and the two ends of the first spring 12 are fixedly connected to the connecting block 10 and the protective plate 4 respectively.

[0028] When in use, the positioning mechanism releases the positioning of the U-shaped block 5, pulls the U-shaped block 5 to move the protective plate 4 and compress the first spring 12. When the baffle 6 on the protective plate 4 moves to the blade of the flying knife 2, the flying knife 2 no longer abuts against the baffle 6. At this time, the stretched second spring 14 resets and pulls the baffle 6 out of the mounting groove on the protective plate 4 to protect the blade. Then, the positioning mechanism positions the moved U-shaped block 5. When the protection is released, the compressed first spring 12 will quickly push the protective plate 4 into the connecting groove through the reset action. Since the baffle 6 is provided with a slope, when the protective plate 4 retracts into the pressure plate 3, the blade will squeeze the slope of the baffle 6, causing the baffle 6 to retract into the mounting groove. After that, the flying knife 2 abuts against the baffle 6, restricting the baffle 6 from moving out of the mounting groove.

[0029] The U-shaped block 5 has a cavity, and a fixed plate 16 is slidably connected inside the cavity. The fixed plate 16 is rotatably connected to the rotating column 8. Two third springs 18 are fixedly connected between the fixed plate 16 and the inner wall of the cavity. A third round rod 17 is symmetrically fixed inside the cavity and slides through the fixed plate 16. The two third springs 18 are respectively sleeved on the two third round rods 17. The rotating column 8 slides through the U-shaped block 5. Limiting blocks 15 are symmetrically fixed on the outer surface of the U-shaped block 5 and slide through the top of the U-shaped block 5. The pressure plate 3 has multiple positioning holes 9, and the end of the rotating column 8 is adapted to the positioning holes 9. The U-shaped block 5 is slidably connected to the pressure plate 3. A connecting rod 7 is symmetrically provided on the outer wall of the U-shaped block 5, and the end of the connecting rod 7 is fixedly connected to the protective plate 4.

[0030] In use, the upward rotating column 8 drives the fixed plate 16 to stretch the third spring 18. Then, the rotating column 8 is rotated so that the limiting block 15 abuts against the top of the U-shaped block 5. At this time, the rotating column 8 moves out of the positioning hole 9, releasing the positioning of the U-shaped block 5. When the protective plate 4 moves to the appropriate position, the rotating column 8 is rotated so that the limiting block 15 no longer abuts against the top of the U-shaped block 5. At this time, the stretched third spring 18 resets and pulls the fixed plate 16 downward, thereby driving the rotating column 8 to insert into the positioning hole 9 to limit the position of the protective plate 4.

[0031] In summary: During operation, the upward rotating column 8 drives the fixed plate 16 to stretch the third spring 18. Then, the rotating column 8 is rotated so that the limiting block 15 abuts against the top of the U-shaped block 5. At this time, the rotating column 8 moves out of the positioning hole 9, releasing the positioning of the U-shaped block 5. Then, the U-shaped block 5 is pulled to move the protective plate 4 and compress the first spring 12. When the baffle 6 on the protective plate 4 moves to the blade of the flying knife 2, the flying knife 2 no longer abuts against the baffle 6. At this time, the stretched second spring 14 resets and pulls the baffle 6 out of the mounting groove on the protective plate 4 to protect the blade. The rotating column 8 is rotated so that the limiting block 15 no longer abuts against the top of the U-shaped block 5. At this time, the stretched third spring 18 resets and pulls the fixed plate 16 downward, thereby driving the rotating column 8 to insert into the positioning hole 9 and limit the position of the protective plate 4.

[0032] Because the baffle 6 has a sloping surface, when the protective plate 4 retracts into the pressure plate 3, the blade will squeeze the sloping surface of the baffle 6, causing the baffle 6 to retract into the mounting groove. Then the flying knife 2 abuts against the baffle 6, restricting the baffle 6 from moving out of the mounting groove.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
