Description

Technical Field

[0001] This invention relates to a longitudinally positioned, side-positioned multi-blade band saw cutting machine, belonging to the field of cutting machine tool technology. Background Technology

[0002] Multi-blade band saws can process raw materials into multiple finished pieces in a single operation. Existing multi-blade band saws are mostly used for wood processing, and the wood clamping and positioning mechanism is located in the middle of the machine tool. This results in the clamped portion of wood remaining uncut after each cut, leading to material waste. Furthermore, existing multi-blade band saws consist of multiple band saw combinations placed horizontally along the wood conveying direction. The more band saw combinations there are, the larger the horizontal space occupied by the entire cutting equipment, which is detrimental to site planning. Summary of the Invention

[0025] The following is in conjunction with the appendix Figure 1-7 Further explanation of the present invention:

[0026] A longitudinally positioned, side-positioned multi-blade band saw cutting machine tool, wherein a limiting baffle 3 is provided at the end of the feeding conveyor device, the limiting baffle 3 is used to limit the material stroke and prevent the material from overtraveling, a feeding plate 1 is provided at the end of the feeding conveyor device, the feeding plate 1 is used to push the material from the feeding conveyor device to the slide table 2, the slide table 2 is movably set on the side of the feeding conveyor device by a driving device a, a pressing device is provided at the end of the slide table 2, a pushing device is provided on the side of the slide table 2, a band saw cutting device is provided on the other side of the slide table 2, and a movable baffle is provided on the side of the band saw cutting device to prevent the material from being pushed overtraveling by the pushing device.

[0027] The feeding and conveying device includes a feeding conveyor belt 4 located on the frame a6. The feeding conveyor belt 4 has a driving roller a5 and a driven roller a at both ends, and a feeding motor is connected to the driving roller a5. The feeding motor drives the driving roller a5 to rotate, and the driving roller a5 drives the feeding conveyor belt 4 to move, so as to realize the moving feeding of the feeding conveyor belt 4.

[0028] The feeding plate 1 is slidably connected to the frame a6, and the feeding plate 1 is connected to the feeding cylinder. The material on the feeding conveyor belt 4 stops at the limiting baffle 23. The feeding plate 1 is located to the side of the material stopping position. Under the action of the feeding cylinder, the feeding plate 1 pushes the material from the feeding conveyor belt 4 onto the slide table 2. The pressing device includes a pressing plate 9, the end of which is slidably connected to the support frame 22 on the slide table 2. The output end of the pressing cylinder is connected to the pressing plate 9. After the material is pushed onto the slide table 2, it stops below the pressing plate 9. The pressing cylinder drives the pressing plate 9 to move downward, pressing the material below.

[0029] The drive device a includes a motor a8 fixed on the frame b7. The motor a8 is connected to a drive screw, which is threadedly connected to a drive nut fixed to the bottom of the slide table 2. The slide table 2 is slidably connected to the frame b7. The motor a8 drives the slide table 2 to move through the cooperation of the drive screw and the drive nut. The slide table 2 can drive the material on it to move towards the working area of ​​the band saw cutting device.

[0030] The pushing device includes a pushing plate 10, which is slidably connected to a slide table 2. The output end of a pushing motor is connected to the pushing plate 10. A baffle plate is slidably connected to a frame a6, and the output end of a baffle cylinder is connected to the baffle plate. After the material passes through the working area of ​​the band saw cutting device, it is cut. After cutting, the baffle plate extends, and the uncut material on the slide table 2 returns to its original position. The cut material is blocked by the baffle plate and does not move. After the slide table 2 returns to its original position, the pressure plate 9 moves upward to release the material. Driven by the pushing motor, the pushing plate 10 pushes the material along the slide table 2, allowing the material to pass through the working area of ​​the band saw cutting device again, preparing for the next cutting operation.

[0031] The band saw cutting device includes an outer band saw, a middle band saw, and an inner band saw. The outer band saw is wound around a drive wheel a11, a driven wheel a12, and an outer belt pulley 13. The middle band saw is wound around a drive wheel b14, a driven wheel b15, and a middle belt pulley 16. The inner band saw is wound around a drive wheel c and an inner belt pulley 17 at both ends. The outer belt pulley 13, the middle belt pulley 16, and the inner belt pulley 17 are coplanarly arranged on a frame c21. The drive wheels a11, b14, and c are respectively connected to band saw motors a, b, and c. The outer, middle, and inner band saws are spaced at the same distance and cut synchronously, which can cut the material into three equal-width segments that meet the required composite width.

[0032] The slide table 2 is equipped with a material feeding conveyor at its end. The material feeding conveyor includes a material feeding conveyor belt 19 located on the frame d18. The two ends of the material feeding conveyor belt 19 are respectively equipped with a drive roller b20 and a driven roller b. The material feeding motor is connected to the drive roller b20. As the slide table 2 moves towards the working area of ​​the band saw cutting device, it pushes the material cut off in the previous cutting cycle onto the material feeding conveyor belt 19 at the end of the slide table 2. The material feeding conveyor belt 19 then transports the cut material to the collection area for centralized storage by the staff.

[0033] The bottom of the frame c21 is provided with an adjustment device, which includes a connecting rod 23 connected to the frame c21. A connecting frame 24 is fixed to the bottom of the connecting rod 23. The connecting frame 24 is provided with three sets of band saw position adjustment components. The three sets of band saw position adjustment components are an outer band saw position adjustment component, a middle band saw position adjustment component, and an inner band saw position adjustment component. Each band saw position adjustment component includes two adjusting bearings 25 with a gap in the middle. The three gaps are used to adjust the lateral position of the outer band saw, the middle band saw, and the inner band saw, respectively. The two adjusting bearings 25 are rotatably connected to the connecting frame 24 by adjusting bolts 26. The adjusting bolts 26 pass through the strip hole on the connecting frame 24 and are threadedly connected to the fixing block 27 on the other side of the connecting frame 24. The specific adjustment process of the band saw's lateral position is as follows: Tighten the adjusting bolt 26, loosen the fixing block 27, move the fixing block 27 laterally along the strip hole, and the fixing block 27 drives the position adjustment component (i.e., the adjusting bearing 25) on the opposite side to move laterally. The gap of the adjusting bearing 25 moves laterally accordingly, and the position of the band saw passing through the gap moves laterally, thereby realizing the lateral adjustment of the band saw's cutting position.

[0034] The connecting rod 23 is slidably connected to the guide rail 29 on the connecting frame 24 via the slider 28. The locking bolt 30 passes through the connecting rod 23 and the slider 28 and contacts the guide rail 29. The locking bolt 30 is threadedly connected to the connecting rod and the slider 28. The vertical movement of the connecting rod 23 can achieve height adjustment. Different products to be cut have different heights, and the distance between the top of the product and the adjusting device varies. If the distance between the adjusting device and the top of the product is too large, the high-speed band saw will vibrate, affecting the cutting quality. Therefore, the height of the adjusting device needs to be adjusted adaptively according to the height of the product to avoid vibration during band saw operation. The height adjustment process of the adjusting device is as follows: Loosen the locking bolt 30 so that the connecting rod 23 can slide along the guide rail 29 via the slider 28. Manually move the connecting rod 23 to adjust its height, thereby adjusting the height position of the adjusting device. After adjustment, tighten the locking bolt 23 to fix the position of the connecting rod 23 and the guide rail 29, thus fixing the height position of the adjusting device. The height adjustment is complete.
