Description

Technical Field

[0001] The present invention relates to the technical field of band sawing machines, in particular to an automatic feeding device for a band sawing machine. Background Art

[0002] Band saws are widely used in metalworking, woodworking, and cutting various materials. They cut materials through the reciprocating motion of the saw blade, offering advantages such as high cutting efficiency, high precision, and a wide range of applications. With the continuous development of industrial production, band saws are increasingly used in industries such as machinery manufacturing, construction, and woodworking, placing higher demands on their performance and automation.

[0003] For example, a band saw machine disclosed in Publication No. CN111408794 A can improve the sawing stability and sawing efficiency of the band saw machine. However, during the sawing process, a portion of sawdust will accumulate between the upper saw band section and the beam plate, making it easy for sawdust to adhere to the saw teeth of the saw band, thereby affecting the sawing stability and service life of the saw band, and affecting the flatness of the cross-section of the workpiece after sawing. However, traditional band saws usually require manual placement of the material to be cut on the cutting table and manual clamping and securing. This method is not only labor-intensive but also inefficient. It is also prone to cutting errors due to improper manual operation, which affects the cutting quality. Therefore, an automatic loading device for band saws is proposed to solve the above problems. Summary of the Invention

[0026] The interior of the cutting table 1 is fixedly connected with an arc-shaped plate 7, which is used to divide the interior of the fixed frame 21 into two cavities. The turntable 32 is set in the left cavity, and the oiling mechanism 8 is set in the right cavity; The oiling mechanism 8 comprises: The rotating disk 81 is rotatably connected to the cutting frame 31 via a transmission shaft, and a driving motor is installed on the outer wall of the cutting frame 31, and the output end of the driving motor is connected to the transmission shaft of the rotating disk 81 for driving the rotating disk 81 to rotate; A plurality of adsorption blocks 82 are fixedly connected to the outer wall of the rotating disk 81 for adsorbing lubricating oil; The oil sleeve 83 is movably connected to the arc plate 7, and the oil sleeve 83 contacts the outer wall of the saw blade 34; The outer wall of the arc plate 7 is fixedly connected with an arc reset plate 84 , and the inner side of the arc reset plate 84 is connected to the oil sleeve 83 through a connecting block 85 , wherein the oil sleeve 83 contacts the adsorption block 82 to guide the lubricating oil to the outer wall of the saw blade 34 .

[0027] Working principle: When cutting, the raw materials to be cut are placed on the conveyor belt 22 on the feeding mechanism 2. At this time, the motor 24 is started, and the drive shaft of one of the conveyor belts 22 is driven to rotate through the pulley group 25, thereby driving the conveyor belt 22 to transmit, so that the raw materials on the conveyor belt 22 can be transported to the side of the cutting table 1. At the same time, the drive shaft of one of the rollers 14 is synchronously driven to rotate through the pulley group 15, so that the raw materials on the roller 14 can be further transported to the right. After the raw materials are transported to the cutting position, the sliders 13 on both sides are synchronously driven to move closer to the raw materials by starting the linear push rod, and the clamping plates 12 are driven closer to each other to clamp the raw materials, thereby limiting the continued transportation of the raw materials, so as to facilitate the cutting of the raw materials. By mechanically adjusting the clamping plates 12 to move closer to each other, the conveying distance can be controlled, thereby maintaining fixed-length transportation and improving transportation efficiency. Furthermore, in order to cut the raw material more stably, the limiting rod 53 can be pushed to move by rotating the adjusting screw 56, thereby pushing the limiting rod 53 to move back and forth in the limiting groove 57. When the limiting rod 53 is out of contact with the protrusion in the limiting groove 57, the rectangular rod 55 can be moved to drive the movable block 54 to move on the sliding rod 58, thereby changing the position of the adjusting assembly 59. At the same time, when the movement is completed, the adjusting screw 56 is reversed to drive the limiting rod 53 to move, so that it enters between the protrusions in the rectangular groove 57 again, thereby limiting the limiting rod 53, thereby limiting the limiting rod 53 again. 3 moves and fixes the adjustment component 59, and when the saw blade 34 is driven by the cutting motor and transmitted to the drive shaft of the turntable 32 through the gear box, the turntable 32 is driven to rotate. At this time, the rotation of the turntable 32 can drive the saw blade 34, and the drive belt of the saw blade 34 and the through groove on the adjustment block 591 can realize the deflection of the saw blade 34, so that the saw blade can be vertically aligned with the raw material, and then the raw material is cut by moving the hydraulic rod 4 downward. At the same time, the saw blade 34 will also contact the slide column 592, which can further improve the guiding effect of the saw blade 34 and improve the vertical shape of the deflected saw blade 34; Furthermore, when the saw blade 34 is working, it will contact the brush sleeve 66. At this time, the waste chips will be resisted by the brush sleeve 66, thereby stripping the waste chips and achieving the effect of separating the waste chips. At the same time, the heat dissipation liquid will be aimed at the saw blade 34 through the external spray pipe to achieve real-time heat dissipation of the saw blade 34. At the same time, when the turntable 32 rotates, it will drive the lever 33 to rotate synchronously, and then the lever 33 will resist the resistance block 62, thereby resisting the sliding sleeve 61 to move downward, and synchronously driving the connecting column 65 and the brush sleeve 66 to move downward. When the lever 33 is separated from the resistance block 62, the spring 63 will push the sliding sleeve 61 upward, so that the brush sleeve 66 can be reset upward. By continuously moving the brush sleeve 66 up and down, the waste chips attached to the outer wall of the saw blade 34 can be further cleaned off, thereby improving the cleaning effect. After starting the driving motor, the rotating disk 81 can be driven to drive the adsorption block 82 to rotate. At this time, the adsorption block 82 is driven to adsorb the lubricating oil in the right cavity and rotate until it contacts the oil sleeve 83. At this time, the lubricating oil on the adsorption block 82 contacts and is scraped off through the oil sleeve 83, and the oil is guided to the side of the saw blade 34 through the oil sleeve 83. After contacting the oil sleeve 83, the arc-shaped reset plate 84 is deformed. After the adsorption block 82 is out of contact with the oil sleeve 83, the lubricating oil can be evenly applied to the outer wall of the saw blade 34. The arc-shaped reset plate 84 is reset, driving the connecting block 85 and the oil sleeve 83 to reset, thereby realizing a reciprocating cycle to oil the saw blade 34.

The above is only a preferred embodiment of the present invention.
