Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a belt saw with multi-angle cutting function. Background Technology

[0002] As a commonly used cutting tool, the belt saw is widely used in various industries such as wood processing, metal processing, and stone processing due to its advantages of high cutting efficiency and wide applicability. In actual production operations, it is often necessary to cut workpieces at different angles to meet diverse processing needs.

[0003] However, existing belt saws have significant shortcomings in angle adjustment. Traditional belt saws mostly use a fixed installation method for their cutting mechanism, enabling only unidirectional cutting. When the cutting angle needs to be changed, the operator must manually adjust the workpiece's position, which is not only cumbersome and time-consuming but also makes it difficult to guarantee the accuracy of the cutting angle, easily leading to workpiece scrap and increasing production costs. Some adjustable belt saws have complex angle adjustment structures, requiring multiple tools for disassembly, adjustment, and fixation, resulting in numerous steps, low efficiency, and a limited adjustment range, failing to meet the cutting needs of some special angles. Therefore, we propose a belt saw with multi-angle cutting capabilities to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by proposing a belt saw with multi-angle cutting capabilities.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A belt saw with multi-angle cutting function includes a gantry frame fixedly connected to the top of a workpiece conveyor table. A mounting frame is provided inside the gantry frame, and two connecting frames are provided inside the mounting frame. A belt saw mechanism is provided between the two connecting frames. A synchronous angle adjustment mechanism is provided between the mounting frame and the two connecting frames. The mounting frame is rotatably connected to the top inner wall of the gantry frame. An angle adjustment mechanism is provided between the mounting frame and the gantry frame. The synchronous angle adjustment mechanism includes a drive shaft and two adjusting shafts. Two fixing plates are fixedly connected to both sides of the gantry frame.

[0007] Preferably, the synchronous angle adjustment mechanism further includes two transmission cavities opened within the mounting frame. The drive shaft is rotatably connected to both sides of the mounting frame. Two active teeth are fixedly sleeved on the outer side of the drive shaft. Two adjustment shafts are rotatably connected to the inner walls of both sides of the mounting frame. Driven teeth are fixedly sleeved on the outer side of each of the two adjustment shafts. Two connecting frames are fixedly connected to one end of the corresponding adjustment shaft. The two active teeth mesh with the corresponding driven teeth. A moving rod is slidably sleeved inside the drive shaft. A push plate is fixedly connected to one end of the moving rod. A compression spring is fixedly connected to one side of the push plate. A disc is fixedly connected to the other end of the moving rod. Two damping rods are fixedly connected to one side of the disc. A plurality of slots are opened on one side of the mounting frame, with the drive shaft as the axis and evenly spaced around it. The two damping rods are respectively damped and engaged in the corresponding slots.

[0008] Preferably, one end of the drive shaft extends to the outside of the mounting bracket and is fixedly connected to a handwheel, and one end of the compression spring is fixedly connected to one side of the handwheel.

[0009] Preferably, the compression spring is sleeved on the outside of the moving rod.

[0010] Preferably, a lower pointer is fixedly connected to the bottom of the right-end adjustment shaft, and a lower angle gauge is fixedly connected to one side of the mounting bracket.

[0011] Preferably, a magnet is fixedly connected inside the slot, and the damping rod is attracted to the magnet.

[0012] Preferably, the tilt adjustment mechanism includes a hydraulic cylinder rotatably connected to the inner wall of the top of the gantry frame, two rotating blocks fixedly connected to the top of the mounting frame, and two vertical plates fixedly connected to the inner wall of the top of the gantry frame. The two vertical plates are rotatably connected to the same rotating shaft, and the two rotating blocks are fixedly sleeved on the outside of the rotating shaft. A connecting rod is fixedly connected to the output shaft of the hydraulic cylinder, and the bottom end of the connecting rod is rotatably connected to the top of the mounting frame.

[0013] Preferably, two upper ear plates are fixedly connected to the top inner wall of the gantry frame, the hydraulic cylinder is rotatably connected between the two upper ear plates, two lower ear plates are fixedly connected to the top of the mounting frame, and the connecting rod is rotatably connected between the two lower ear plates.

[0014] Preferably, an upper pointer is fixedly connected to the top of the rotating shaft, and an upper angle ruler is fixedly connected to the front side of the front vertical plate.

[0015] Preferably, the belt saw mechanism includes two pulleys rotatably connected to the inner walls of the front and rear sides of the connecting frame, and a drive motor fixedly connected to the front side of the connecting frame on the left side. The output shaft of the drive motor is fixedly connected to the front end of the corresponding pulley, and the same belt saw is driven on the two pulleys.

[0016] In this utility model, a belt saw with multi-angle cutting function is described. To avoid torsional deformation of the belt saw due to different rotation angles of the two adjusting shafts, the push plate is pushed backward according to the workpiece cutting angle. This causes the moving rod to move to the left, which in turn moves the disc and two damping rods to the left, disengaging them from the slots. This prevents the drive shaft from being locked. At this time, the drive shaft and two active teeth can be rotated by the handwheel. The two active teeth drive the two driven teeth and the adjusting shaft to rotate synchronously. In turn, the two adjusting shafts synchronously drive the two connecting frames and the belt saw to rotate around the adjusting shaft as the axis. This allows for synchronous angle adjustment of the belt saw, preventing torsional deformation and damage. The lower pointer and lower angle ruler indicate the angle of the belt saw, allowing for precise adjustment. After adjustment, the push plate is released. Under the elastic force of the compression spring, the push plate and moving rod return to the right, driving the disc and damping rods to move to the right and return to their original positions, inserting them into the corresponding slots and attracting them to the magnets. This locks the drive shaft and adjusting shaft, greatly improving the stability of the belt saw during cutting.

[0017] In this utility model, a belt saw with multi-angle cutting function is described. Activating the hydraulic cylinder causes the output shaft of the hydraulic cylinder to extend or retract the connecting rod, which in turn causes the mounting bracket to rotate around the pivot, thus adjusting the left and right tilt angles of the belt saw. Precise adjustment of the left and right tilt angles is achieved through the indication of the upper pointer and upper angle gauge. After adjustment, the hydraulic cylinder is deactivated, and the drive motor is activated. The drive motor drives the pulley and belt saw, while the conveyor table transports the workpiece backward, allowing the belt saw below to perform the cutting operation.

[0018] This utility model has a reasonable structural design. Through the synchronous angle adjustment mechanism, the two adjustment shafts can be driven to rotate synchronously, avoiding the situation where the belt saw is damaged by torsional deformation due to asynchronous rotation. After adjustment, the two adjustment shafts can be locked to improve the stability during cutting. At the same time, the working angle of the belt saw can be adjusted, making the device more versatile. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A belt saw with multi-angle cutting function includes a gantry frame 1 fixedly connected to the top of the workpiece conveyor table. A mounting frame 3 is provided inside the gantry frame 1. Two connecting frames 4 are provided inside the mounting frame 3. A belt saw mechanism 5 is provided between the two connecting frames 4. A synchronous angle adjustment mechanism 6 is provided between the mounting frame 3 and the two connecting frames 4. The mounting frame 3 is rotatably connected to the top inner wall of the gantry frame 1. An angle adjustment mechanism 7 is provided between the mounting frame 3 and the gantry frame 1. The synchronous angle adjustment mechanism 6 includes a drive shaft 61 and two adjustment shafts 612. Two fixing plates 2 are fixedly connected to both sides of the gantry frame 1.

[0026] Specifically, refer to Figure 1 , Figure 2 and Figure 4The synchronous angle adjustment mechanism 6 also includes two transmission cavities 613 opened in the mounting frame 3. The drive shaft 61 is rotatably connected to both sides of the mounting frame 3. Two active teeth 66 are fixedly sleeved on the outer side of the drive shaft 61. Two adjustment shafts 612 are rotatably connected to the inner walls of both sides of the mounting frame 3. Driven teeth 611 are fixedly sleeved on the outer side of both adjustment shafts 612. Two connecting frames 4 are fixedly connected to one end of the corresponding adjustment shaft 612. The two active teeth 66 mesh with the corresponding driven teeth 611. A moving rod 64 is slidably sleeved in the drive shaft 61. A push plate 65 is fixedly connected to one end of the moving rod 64. A compression spring 63 is fixedly connected to one side of the push plate 65. A disc 67 is fixedly connected to the other end of the moving rod 64. Two damping rods 68 are fixedly connected to one side of the disc 67. A plurality of slots 614 are opened on one side of the mounting frame 3, which are evenly distributed in a circle with the drive shaft 61 as the axis. The two damping rods 68 are respectively damped and engaged in the corresponding slots 614.

[0027] Using the above solution: To avoid the belt saw twisting due to the different rotation angles of the two adjusting shafts 612, the push plate 65 is pushed backward, causing the moving rod 64 to move to the left and drive the disc 67 and the two damping rods 68 (which can be made of iron and covered with a high-friction rubber sleeve) to move to the left and disengage from the slot 614. This prevents the drive shaft 61 from being locked. At this point, the handwheel 62 can be used to rotate the drive shaft 61 and the two driving teeth 66. The two driving teeth 66 drive the two driven teeth 611 and the adjusting shaft 612 to rotate synchronously. Consequently, the two adjusting shafts 612 synchronously drive the two connecting frames 4 and the belt saw 53 to adjust the shaft 612. The belt saw 53 rotates around axis 12, allowing for synchronous angle adjustment and preventing damage from torsional deformation. The angle of the belt saw 53 can be precisely adjusted via the lower pointer 69 and lower angle gauge 610. After adjustment, the push plate 65 is released, and under the force of the compression spring 63, the push plate 65 and moving rod 64 return to their rightward position. This drives the disc 67 and damping rod 68 to move to their rightward position and insert into the corresponding slot 614, where they are attracted and fixed to the magnet 615. This locks the drive shaft 61, thereby locking the adjusting shaft 612 and greatly improving the stability of the belt saw 53 during cutting.

[0028] Specifically, one end of the drive shaft 61 extends to the outside of the mounting bracket 3 and is fixedly connected to the handwheel 62. One end of the compression spring 63 is fixedly connected to one side of the handwheel 62 to facilitate the rotation of the handwheel 62. In the initial state, the compression spring 63 is under pressure, which allows the damping rod 68 to be inserted into the slot 614 more stably.

[0029] Specifically, the compression spring 63 is sleeved on the outside of the moving rod 64, which facilitates the guiding and limiting of the compression spring 63.

[0030] Specifically, a lower pointer 69 is fixedly connected to the bottom of the right-end adjusting shaft 612, and a lower angle ruler 610 is fixedly connected to one side of the mounting bracket 3. The angle of the belt saw 53 can be precisely adjusted by the indication of the lower pointer 69 and the lower angle ruler 610.

[0031] Specifically, a magnet 615 is fixedly connected inside the slot 614, and the damping rod 68 is attracted to the magnet 615. Through the magnetic attraction between the magnet 615 and the damping rod 68, the damping rod 68 is prevented from falling out of the slot 614.

[0032] Specifically, refer to Figures 1-3 The tilt adjustment mechanism 7 includes a hydraulic cylinder 72 rotatably connected to the inner wall of the top of the gantry frame 1, two rotating blocks 75 fixedly connected to the top of the mounting frame 3, and two vertical plates 76 fixedly connected to the inner wall of the top of the gantry frame 1. The two vertical plates 76 are rotatably connected to the same rotating shaft 77. The two rotating blocks 75 are fixedly sleeved on the outside of the rotating shaft 77. A connecting rod 73 is fixedly connected to the output shaft of the hydraulic cylinder 72. The bottom end of the connecting rod 73 is rotatably connected to the top of the mounting frame 3. An upper pointer 78 is fixedly connected to the top of the rotating shaft 77. An upper angle ruler 79 is fixedly connected to the front side of the front vertical plate 76.

[0033] Using the above scheme: start the hydraulic cylinder 72, so that the output shaft of the hydraulic cylinder 72 drives the connecting rod 73 to extend or retract, thereby driving the mounting bracket 3 to rotate and adjust around the rotating shaft 77 as the axis, thereby adjusting the left and right tilt angle of the belt saw 53. And through the indication of the upper pointer 78 and the upper angle ruler 79, the left and right tilt angle of the belt saw 53 can be precisely adjusted. After the adjustment is completed, turn off the hydraulic cylinder 72.

[0034] Specifically, two upper ear plates 71 are fixedly connected to the top inner wall of the gantry frame 1, and the hydraulic cylinder 72 is rotatably connected between the two upper ear plates 71. Two lower ear plates 74 are fixedly connected to the top of the mounting frame 3, and the connecting rod 73 is rotatably connected between the two lower ear plates 74, which facilitates the rotatable connection of the hydraulic cylinder 72 to the top inner wall of the gantry frame 1, and at the same time, the connecting rod 73 can be rotatably connected to the top of the mounting frame 3.

[0035] Specifically, refer to Figure 1 The belt saw mechanism 5 includes two pulleys 51 rotatably connected to the inner walls of the front and rear sides of the connecting frame 4, and a drive motor 52 fixedly connected to the front side of the connecting frame 4 on the left side. The output shaft of the drive motor 52 is fixedly connected to the front end of the corresponding pulley 51, and the same belt saw 53 is drivenly connected to the two pulleys 51.

[0036] Using the above scheme: start the drive motor 52, drive the pulley 51 and belt saw 53 to run, and the conveyor table transports the workpiece backward, so that the workpiece can be cut by the belt saw 53 below.

[0037] In this invention, the device is mounted on the workpiece conveyor table via the fixing plate 2. The conveyor table not only effectively fixes the workpiece but also facilitates its backward transport. To prevent the belt saw from twisting and deforming due to the different rotation angles of the two adjusting shafts 612, the push plate 65 is pushed backward, causing the moving rod 64 to move to the left and drive the disc 67 and the two damping rods 68 (which can be made of iron and covered with a high-friction rubber sleeve) to move to the left and disengage from the slot 614. This prevents the drive shaft 61 from being locked. At this point, the drive shaft 61 and the two driving teeth 66 can be rotated via the handwheel 62. The two driving teeth 66 drive the two driven teeth 611 to rotate synchronously with the adjusting shaft 612, thereby causing the two adjusting shafts... The 612 synchronously drives the two connecting frames 4 and the belt saw 53 to rotate around the adjusting shaft 612, thereby synchronously adjusting the angle of the belt saw 53 and preventing the belt saw 53 from being damaged by torsional deformation. The lower pointer 69 and the lower angle ruler 610 indicate that the angle of the belt saw 53 can be precisely adjusted. After the adjustment is completed, the push plate 65 is released. At this time, under the elastic force of the compression spring 63, the push plate 65 and the moving rod 64 are reset to the right, thereby driving the disc 67 and the damping rod 68 to move to the right and reset and insert into the corresponding slot 614, and attract and fix them to the magnet 615, thereby locking the drive shaft 61, and thus locking the adjusting shaft 612, greatly improving the stability of the belt saw 53 during cutting.

[0038] Start the hydraulic cylinder 72, causing the output shaft of the hydraulic cylinder 72 to extend or retract the connecting rod 73, which in turn causes the mounting bracket 3 to rotate around the pivot shaft 77, thereby adjusting the left and right tilt angle of the belt saw 53. The left and right tilt angle of the belt saw 53 can be precisely adjusted by the indication of the upper pointer 78 and the upper angle ruler 79. After the adjustment is completed, turn off the hydraulic cylinder 72 and start the drive motor 52. The drive motor 52 drives the pulley 51 and the belt saw 53 to run, and the conveyor table transports the workpiece backward, so that the belt saw 53 below can cut the workpiece.
