Description

Technical Field

[0001] This invention relates to the field of multi-blade sawing technology, and more specifically to a high-speed multi-blade sawing device. Background Technology

[0002] A multi-blade saw mainly consists of a frame, a transmission mechanism, a cutter shaft, multiple sets of circular saw blades mounted on the cutter shaft, and a feeding mechanism. The feeding mechanism feeds the positioned board material at a uniform speed into the saw blades for cutting into the required sheet-like finished products, which can greatly improve production efficiency. Multi-blade saws can improve the efficiency of cutting board strips. They generally adopt a high-speed sawing mode and can use either a wire saw or a circular saw to cut whole wood boards into small boards of corresponding sizes.

[0003] In the process of driving a multi-blade saw to cut at high speed simultaneously, a unified drive unit is generally used to drive multiple saw blades to rotate synchronously at high speed, thereby cutting the whole board into small boards of corresponding sizes. However, since the saw blades are directly mounted on the shaft, the spacing between the saw blades cannot be adjusted, meaning that only a whole board can be cut into small boards of uniform size at a time. Furthermore, the installation angle of the saw blades is difficult to adjust, resulting in the sawing angle of a single saw blade being locked. It is impossible to cut the whole board into small boards with a certain edge offset according to actual needs. In other words, the position and sawing angle of the saw blades are difficult to control, ultimately limiting the sawing scenarios of multi-blade saws.

[0004] Therefore, it is necessary to invent a high-speed sawing device for multi-blade saws to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a high-speed multi-blade sawing device. This device solves the problems in existing technologies where the saw blades are directly mounted on the shaft, resulting in an unadjustable blade spacing. This means that a single cut can only cut a whole board into smaller boards of uniform size. Furthermore, the installation angle of the saw blades is difficult to adjust, leading to a locked sawing angle for a single blade. This makes it impossible to cut the whole board into smaller boards with a certain edge offset according to actual needs. In other words, the position and sawing angle of the saw blades are difficult to control, ultimately limiting the sawing scenarios of multi-blade saws.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-speed multi-blade saw includes a U-shaped base frame, a base plate longitudinally lifted and disposed within the U-shaped base frame for placing the material to be sawed, and a sawing assembly that can slide laterally along the top surface of the U-shaped base frame. The sawing assembly includes a rotatable rotating rod and multiple sawing structures that can slide along the length of the rotating rod and rotate at any position. The outer left and right side walls of the rotating rod are both flat. A central guide groove is longitudinally formed in the middle of the rotating rod. The flat side walls of the rotating rod are both formed with side guide grooves that can communicate with the central guide groove. The sawing structure includes two detachably connected semi-circular brackets and a saw blade detachably sleeved between the outer peripheral side walls of the two semi-circular brackets. The middle of the two semi-circular brackets, which are close to each other on one side wall, are connected to a turntable by a connecting stud. The two turntables within the same sawing structure are engaged and can slide and rotate along the central guide groove. The connecting stud can slide and rotate along the side guide groove, and the part of the connecting stud located outside the rotating rod is threaded with a first nut that can lock the sliding position and rotation angle of the connecting stud.

[0008] As a preferred embodiment of the present invention, an anti-rotation bracket is installed on the side wall of one of the turntables in the same sawing structure, and an anti-rotation slot is provided in the other turntable for inserting the anti-rotation bracket and preventing the two turntables from rotating relative to each other.

[0009] As a preferred embodiment of the present invention, each of the two semi-circular brackets has a mounting groove in the middle of one side wall where they contact each other, and a mounting stud is detachably engaged between the two mounting grooves at the same position. The mounting stud has a second nut threaded on both sides of its side wall to lock the mounting stud in the mounting groove.

[0010] As a preferred embodiment of the present invention, fastening plates that can be connected to the inner peripheral sidewall of the semi-circular card holder are installed at symmetrical positions of the turntable.

[0011] In a preferred embodiment of the present invention, a first top plate is provided on the top surface of one side of the U-shaped base frame, and a second top plate is provided on the top surface of the other side of the U-shaped base frame. A first slide rail is installed at the top of the first top plate, and a second slide rail is installed at the top of the second top plate. A first slide block is slidably provided on the first slide rail, and a first base is detachably installed at the top of the first slide block. The sawing assembly further includes a driving component that can drive the rotating rod to rotate. The driving component is detachably installed on the first base via a mounting seat. A second slide block is slidably provided on the second slide rail, and a second base is detachably installed at the top of the second slide block. Semicircular chucks are installed at the top of both the first base and the second base. An arc-shaped protective cylinder is slidably installed between the two semicircular chucks, and multiple saw blades are located inside the arc-shaped protective cylinder.

[0012] As a preferred embodiment of the present invention, a lifting frame is installed at the top of the outer peripheral sidewall of the arc-shaped protective cylinder, and multiple chip blowing pipes that can blow air in the sawing direction are connected to the outer peripheral sidewall of the arc-shaped protective cylinder. The semi-circular chuck has vertical grooves from top to bottom. Both ends of the inner peripheral sidewall of the arc-shaped protective cylinder are connected to positioning studs through connecting plates. The positioning studs can slide longitudinally along the vertical grooves, and the portion of the positioning studs located outside the vertical grooves is threaded with a third nut.

[0013] When the positioning stud slides to the bottom of the vertical groove, the outer circle of the arc-shaped protective cylinder coincides with the outer circle of the semi-circular chuck.

[0014] As a preferred embodiment of the present invention, a locking plate is detachably installed at the bottom end of the semi-circular chuck located at the top of the second base, a sleeve is sleeved at the end of the rotating rod away from the driving component, a rotating column is installed in the middle of the other end of the sleeve, a bearing is embedded between the locking plate and the semi-circular chuck, and the rotating column is rotatably inserted into the bearing.

[0015] As a preferred embodiment of the present invention, lifting components are installed at the four corners inside the U-shaped base frame, and the base plate is detachably installed between the tops of multiple lifting components.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0017] In this invention, the high-speed rotation of the rotating rod drives multiple saw blades to simultaneously cut at high speed, thereby cutting the whole board into multiple smaller boards. During the actual sawing process, the installation position of the saw blade on the rotating rod can be adjusted by changing the positions of the two semi-circular brackets within the central guide groove of a single sawing structure. Simultaneously, the installation angle of the saw blade at any position on the rotating rod can be adjusted by driving the semi-circular brackets to rotate within the central guide groove, thus adjusting the subsequent sawing angle. During the sliding and rotation of the semi-circular brackets within the central guide groove, the connecting studs simultaneously slide within the side guide grooves. The movement and rotation can be locked by simply rotating the first nut, which locks the sliding position and rotation angle of the connecting stud in the side guide groove. The entire locking action is simple and efficient, thereby locking the sliding position and rotation angle of the semi-circular bracket in the middle guide groove, and finally locking the installation position and installation angle of the saw blade on the rotating rod. This allows for adjustment of the subsequent sawing position and sawing angle, making it convenient to saw small boards of different sizes in a single sawing process of a whole board, as well as small boards of different sizes with a certain deflection angle on the edge, thus enriching the sawing scenarios of multi-blade saws.

[0028] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0029] This invention provides, for example Figure 1-8The multi-blade saw high-speed sawing device shown includes a U-shaped base frame 1, a base plate 9 longitudinally lifted and disposed within the U-shaped base frame 1 for placing the material to be sawed, and a sawing assembly that can slide laterally along the top surface of the U-shaped base frame 1. The sawing assembly includes a rotatable rotating rod 13 and multiple sawing structures that can slide along the length of the rotating rod 13 and rotate at any position. The left and right side walls of the rotating rod 13 are both flat. A central guide groove 14 is longitudinally formed in the middle of the rotating rod 13. The flat side walls of the rotating rod 13 are both formed inward with side guide grooves 15 that can communicate with the central guide groove 14. The sawing structure includes two detachably connected... The two semi-circular brackets 16 are detachably fitted between the outer peripheral sidewalls of the two semi-circular brackets 16. The two semi-circular brackets 16 are connected to a turntable 18 by a connecting stud 17 at the middle of one sidewall of each other. The two turntables 18 in the same sawing structure are engaged and can slide and rotate along the middle guide groove 14. The connecting stud 17 can slide and rotate along the side guide groove 15. The part of the connecting stud 17 outside the rotating rod 13 is threaded with a first nut 21 that can lock the sliding position and rotation angle of the connecting stud 17. After the two semi-circular brackets 16 are in contact, the outer circle is in a complete circle shape, which facilitates the installation and fixing of the saw blade 26.

[0030] In the same sawing structure, one of the turntables 18 has an anti-rotation bracket 19 installed on its side wall, and the other turntable 18 has an anti-rotation slot 20 for inserting the anti-rotation bracket 19 and preventing the two turntables 18 from rotating relative to each other. After the anti-rotation bracket 19 is inserted into the anti-rotation slot 20, the position between the two turntables 18 is locked, and unnecessary rotation cannot occur, so that unnecessary deflection will not occur between the two semi-circular brackets 16.

[0031] The two semi-circular brackets 16 are provided with mounting grooves 23 in the middle of the side wall where they contact each other. The two mounting grooves 23 at the same position are detachably connected to the mounting studs 24. The two sides of the mounting studs 24 are threaded with second nuts 25 that can lock the mounting studs 24 in the mounting grooves 23. The mounting studs 24 and the second nuts 25 can lock the position between the two semi-circular brackets 16.

[0032] Fastening plates 22 that can be connected to the inner peripheral sidewall of the semi-circular bracket 16 are installed at symmetrical positions on the turntable 18. The fastening plates 22 can strengthen the connection between the turntable 18 and the semi-circular bracket 16.

[0033] A first top plate 2 is provided on the top surface of one side of the U-shaped base frame 1, and a second top plate 3 is provided on the top surface of the other side of the U-shaped base frame 1. A first slide rail 4 is installed at the top of the first top plate 2, and a second slide rail 6 is installed at the top of the second top plate 3. A first slide block 5 is slidably arranged on the first slide rail 4, and a first base 10 is detachably installed at the top of the first slide block 5. The sawing assembly also includes a driving component 12 that can drive the rotating rod 13 to rotate. The driving component 12 is detachably installed on the first base 10 through the mounting base 11. A second slide block 7 is slidably arranged on the second slide rail 6, and a second base 28 is detachably installed at the top of the second slide block 7. A semi-circular chuck 29 is installed at the top of both the first base 10 and the second base 28. An arc-shaped protective cylinder 30 is slidably installed between the two semi-circular chucks 29, and multiple saw blades 26 are located inside the arc-shaped protective cylinder 30. During the process of the first slide block 5 sliding along the first slide rail 4, the second slide block 7 slides synchronously along the second slide rail 6, thereby changing the position of the sawing assembly on the top surface of the U-shaped base frame 1.

[0034] A lifting bracket 31 is installed at the top of the outer peripheral side wall of the arc-shaped protective cylinder 30. Multiple chip blowing pipes 32 that can blow air in the sawing direction are connected to the outer peripheral side wall of the arc-shaped protective cylinder 30. The semi-circular chuck 29 has a vertical groove 33 from top to bottom. Both ends of the inner peripheral side wall of the arc-shaped protective cylinder 30 are connected to positioning studs 35 through connecting plates 34. The positioning studs 35 can slide longitudinally along the vertical groove 33. The part of the positioning stud 35 located outside the vertical groove 33 is threaded with a third nut 36. When the positioning stud 35 slides to the bottom of the vertical groove 33, the outer circle of the arc-shaped protective cylinder 30 coincides with the outer circle of the semi-circular chuck 29. When it is necessary to change the installation position of the single saw blade 26 on the rotating rod 13 and the sawing angle, the arc-shaped protective cylinder 30 can be disassembled from the two semi-circular chucks 29 through the lifting bracket 31.

[0035] A locking plate 38 is detachably installed at the bottom of the semi-circular chuck 29 located at the top of the second base 28. A sleeve 27 is fitted at the end of the rotating rod 13 away from the driving component 12. A rotating column 39 is installed in the middle of the other end of the sleeve 27. A bearing 37 is embedded between the locking plate 38 and the semi-circular chuck 29. The rotating column 39 rotates through the bearing 37. During the process of the driving component 12 driving the rotating rod 13 to rotate, the rotating column 39 rotates synchronously in the bearing 37, thereby improving the stability of the rotation of the rotating rod 13.

[0036] Lifting components 8 are installed at the four corners of the U-shaped base frame 1. The base plate 9 can be detachably installed between the tops of multiple lifting components 8. The lifting components 8 change the longitudinal distance between the base plate 9 and the saw blade 26, which makes it convenient to place plates of different thicknesses on the base plate 9, and also makes it convenient to saw grooves of different depths on the plates.

[0037] In this invention, the high-speed rotation of the rotating rod 13 drives multiple saw blades 26 to simultaneously cut at high speed, thereby cutting the whole board into multiple smaller boards. During the actual sawing process, the installation position of the saw blade 26 on the rotating rod 13 can be adjusted by changing the position of the two semi-circular brackets 16 within the middle guide groove 14 in a single sawing structure. Simultaneously, the installation angle of the saw blade 26 at any position on the rotating rod 13 can be adjusted by driving the semi-circular brackets 16 to rotate within the middle guide groove 14, thus adjusting the subsequent sawing angle. During the sliding and rotation of the semi-circular brackets 16 within the middle guide groove 14, the connecting stud 17 provides lateral guidance. The saw blade slides and rotates synchronously within the groove 15. Ultimately, the sliding position and rotation angle of the connecting stud 17 within the side guide groove 15 can be locked simply by rotating the first nut 21. The entire locking action is simple and efficient. This locks the sliding position and rotation angle of the semi-circular bracket 16 within the middle guide groove 14, and finally locks the installation position and angle of the saw blade 26 on the rotating rod 13. This allows for adjustment of the subsequent sawing position and angle, making it convenient to saw small boards of different sizes or small boards of different sizes with a certain deflection angle at the edge during a single sawing process of a whole board, thus enriching the sawing scenarios of multi-blade saws.

[0038] The above description is only a preferred embodiment of the present invention. 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 invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
