Description

Technical Field

[0001] This invention relates to the field of saw blade technology, specifically a saw blade alignment device for an automatic saw blade end annealing line. Background Technology

[0002] Annealing is a metal heat treatment process that involves slowly heating a metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize dimensions, reduce deformation and cracking tendency, refine grain size, adjust microstructure, and eliminate structural defects. More precisely, annealing is a heat treatment process for materials, including metallic and non-metallic materials. Furthermore, the annealing objectives for new materials differ from those of traditional metal annealing. Saw blades are widely used in various industries such as machinery manufacturing, wood processing, metallurgy, chemicals, and military. Saw blades are divided into frame saw blades and band saw blades. Frame saw blades are thin and long, with several teeth on one symmetrical side of the saw back. These saws are mounted on frame saw machines for sawing workpieces. Band saw blades are thin and long, with several teeth on one symmetrical side of the saw back, and are mounted on band saw machines for sawing operations.

[0003] Currently, the hand-held hacksaw blade industry requires saw blades to undergo annealing treatment. Annealing saw blades requires the use of a saw blade annealing machine. However, the saw blade alignment device of the saw blade annealing machine is not perfect during the annealing process, resulting in an unsatisfactory alignment effect of the saw blade, which affects the length requirements and annealing accuracy of the ends of the saw blade that need to be annealed.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a saw blade alignment device for an automatic saw blade end annealing line, which has the following beneficial effects:

[0017] (1) The saw blade alignment device of the automatic saw blade end annealing line, when the saw blade needs to be aligned, firstly, the spacing needs to be adjusted according to the size of the saw blade. First, pull the locking rod to the left to release the locking rod from the base. Then, rotate the rotating disk. The rotating disk drives the transmission shaft to rotate synchronously. The transmission shaft drives the intermediate sprocket to rotate synchronously. The intermediate sprocket drives the other two sprockets to rotate synchronously through the chain. The front and rear sprockets drive the two threaded rods to rotate synchronously. The two threaded rods drive the two threaded connecting blocks to move back and forth. The two connecting blocks drive the sliding blocks to move back and forth synchronously. After the spacing is adjusted, the sliding blocks are fixed again by the locking rod. Then, start the motor. The motor drives the conveyor shaft to rotate. After the saw blade is placed on the conveyor shaft, the conveyor shaft will move the saw blade backward. During the movement, the saw blade will encounter the inclined surface of the fixed block. Then, the saw blade will move along the inclined surface while adjusting its direction. When the saw blade moves from the inclined surface to the straight surface, the straight surface on the left side of the fixed block and the straight surface on the right side of the sliding block will make the saw blade move in a straight line. All the saw blades that pass through will move in a straight line, which automatically aligns the saw blade. This automatic alignment of the saw blade during the operation of the saw blade annealing machine makes the alignment effect more ideal and faster, avoiding the impact of misalignment on the length requirements and annealing accuracy of the ends of the saw blade that need to be annealed, resulting in a better quality saw blade.

[0018] (2) The saw blade alignment device of the automatic saw blade end annealing line has a locking rod slidably connected to the left side of the rotating disk. The right end of the locking rod slides through the interior of the base, and the right end of the drive shaft rotates through the interior of the drive groove. This allows the locking rod to pass through the rotating disk and extend into the interior of the base. This allows the sliding block to be locked and fixed by the locking rod after adjustment, further improving the stability of the sliding block during use.

[0019] (3) The saw blade alignment device of the automatic saw blade end annealing line has a rotating disk fixedly connected to the left end of the drive shaft, and a sprocket fixedly connected to the right end of the drive shaft. The three sprockets are connected by a chain, so that the sliding block can be controlled by controlling only one rotating disk, which makes the movement of the sliding block more convenient and faster.

[0020] (4) The saw blade alignment device of the automatic saw blade end annealing line has a cleaning block set inside the base. The left side of the cleaning block is fixedly connected to the left wall of the base, and the right side of the cleaning block is fixedly connected to the right wall of the base. The upper side of the cleaning block is set as a scraper. The upper side of the cleaning block can contact the outer surface of the conveyor belt, so that the outer surface of the conveyor belt can be automatically cleaned when the alignment device is working, avoiding the debris attached to the outer surface of the conveyor belt from affecting the horizontal placement of the saw blade and thus affecting the alignment of the saw blade.

[0021] (5) The saw blade alignment device of the automatic saw blade end annealing line has a debris collection box set on the right side of the base. The left side of the debris collection box slides through into the interior of the base. A handle is fixedly connected to the right side of the debris collection box. The cleaning block is set in the middle of the upper side of the debris collection box. After the cleaning block scrapes the debris off the outer surface of the conveyor belt, the scraped debris can fall into the debris collection box. When the debris collection box is full, it can be removed by simply pulling it to process the debris. This makes it more convenient to clean the debris scraped off the outer surface of the conveyor belt, and avoids the situation where the cleaning work is troublesome due to the debris falling everywhere.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 5This invention provides a new technical solution: a saw blade alignment device for an automatic saw blade end annealing line, comprising a base 1, a support leg 11 fixedly connected to the lower side of the base 1, a conveyor shaft 12 rotatably connected to the inner wall of the base 1, a conveyor belt 15 sleeved on the outer surface of the conveyor shaft 12, a motor 2 fixedly connected to the right side of the base 1, the motor 2 driving the conveyor shaft 12 to rotate (since the motor 2 and the conveyor shaft 12 are existing technologies, they will not be explained in detail), a fixing block 3 fixedly connected to the upper side of the base 1, the fixing block 3 being located on the upper right side of the base 1, the fixing block 3 being a right trapezoid in shape, the lower side of the fixing block 3 contacting the conveyor shaft 12, and a sliding block 4 slidably connected to the upper side of the base 1, the lower side of the sliding block 4 also contacting the conveyor shaft 12. The base 1 has a transmission groove 13 inside. Two sliding grooves 14 are formed on the upper side of the base 1, arranged front to back. Connecting blocks 41 are slidably connected inside each sliding groove 14. The upper sides of the two connecting blocks 41 are fixedly connected to the lower sides of the sliding blocks 41. The left walls of the two sliding grooves 14 extend into the interior of the transmission groove 13, and both sliding grooves 14 communicate with the interior of the transmission groove 13. Threaded rods 62 are rotatably connected to the right walls of both sliding grooves 14. The left ends of the two threaded rods 62 are threaded through the left sides of the two connecting blocks 41, extending into the interior of the transmission groove 13. A sprocket 6 is fixedly connected to the left end of each threaded rod 62. A transmission shaft 5 is located on the left side of the base 1, and the left end of the transmission shaft 5 is fixedly connected to... A rotating disk 51 is connected to the base 1. A locking rod 52 is slidably connected to the left side of the rotating disk 51. The right end of the locking rod 52 slides through the interior of the base 1. The right end of the drive shaft 5 rotates through the interior of the drive groove 13. A sprocket 6 is also fixedly connected to the right end of the drive shaft 5. A chain 61 is connected between the three sprockets 6. When starting work, if the saw blade needs to be aligned, the spacing needs to be adjusted according to the size of the saw blade. First, pull the locking rod 52 to the left to release the locking state between the locking rod 52 and the base 1. Then, rotate the rotating disk 51. The rotating disk 51 drives the drive shaft 5 to rotate synchronously. The drive shaft 5 drives the middle sprocket 6 to rotate synchronously. The middle sprocket 6 drives the other two sprockets 6 synchronously through the chain 61. The rotation begins, with the front and rear sprockets 6 driving the two threaded rods 62 to rotate synchronously. The two threaded rods 62 then drive the two threaded connecting blocks 41 to move synchronously to the right. Each connecting block 41 also drives the sliding block 4 to move synchronously to the right. To move the sliding block 4 to the left, the worker simply rotates the turntable 51 in the opposite direction. As described above, the two threaded rods 62 will then drive the two connecting blocks 41 to continue turning synchronously to the left, and the two connecting blocks 41 will drive the sliding block 4 to move synchronously to the left. After the spacing is adjusted, the worker pushes the locking rod 52 to the right, moving the right end of the locking rod 52 into the base 1, thus locking the locking rod 52 to the base 1.The rotating disk 51 cannot rotate. Then, the motor 2 is started. The motor 2 drives the conveyor shaft 12 to rotate, and the conveyor shaft 12 drives the conveyor belt 15 to move synchronously. After the saw blade is placed on the upper side of the conveyor belt 15, the conveyor belt 15 will drive the saw blade to move backward. During the movement, the saw blade will encounter the inclined surface of the fixed block 3. Then, the saw blade will move along the inclined surface while adjusting its direction. When the saw blade moves from the inclined surface to the straight surface, the straight surface on the left side of the fixed block 3 and the straight surface on the right side of the sliding block 4 will cause the saw blade to move in a straight line. All saw blades passing through will move in a straight line. The saw blade is moved, thus automatically aligning it. This method allows for automatic alignment of the saw blade during the saw blade annealing machine's operation, resulting in a more ideal and faster alignment. It avoids misalignment affecting the length requirements and annealing precision at both ends of the saw blade, leading to higher quality saw blades. Simultaneously, the locking rod 52 passes through the rotating disk 51 and extends into the base 1, allowing the sliding block 4 to be locked and fixed after adjustment, further improving its stability during use.

[0030] A debris collection box 7 is located on the right side of the base 1. The left side of the debris collection box 7 slides through the interior of the base 1. A handle 71 is fixedly connected to the right side of the debris collection box 7. A cleaning block 72 is located inside the base 1. The left side of the cleaning block 72 is fixedly connected to the left wall of the base 1, and the right side of the cleaning block 72 is fixedly connected to the right wall of the base 1. A scraper is set on the upper side of the cleaning block 72, which can contact the outer surface of the conveyor belt 15. The cleaning block 72 is located in the middle of the upper side of the debris collection box 7. When starting work, the saw blade is usually coated with anti-rust oil to ensure long-term storage. The anti-rust oil is used to prevent the saw blade from oxidizing and rusting. When the alignment device aligns the saw blade, the anti-rust oil will adhere to the outer surface of the conveyor belt 15. The anti-rust oil adhering to the conveyor belt 15 will cause dust and debris to adhere to it. After the saw blade is placed on the base 1, it will tilt and will no longer be horizontal, which will lead to a decrease in the alignment quality. When the alignment device is started, the conveyor belt 15 will move. At this time, the scraper on the upper side of the cleaning block 72 will scrape off the dust, debris and anti-rust oil attached to the outer surface of the conveyor belt 15. These debris that affect the horizontal position of the saw blade will fall into the debris collection box 7 along the cleaning block 72. When the debris collection box 7 needs to be cleaned, simply pull the handle 71 to the right to remove the debris collection box 7 from the base 1. After emptying the debris inside the debris collection box 7, it can be reinstalled into the base 1. In this way, the outer surface of the conveyor belt 15 can be automatically cleaned when the alignment device is working, avoiding the debris attached to the outer surface of the conveyor belt 15 from affecting the horizontal placement of the saw blade and thus affecting the alignment of the saw blade.

[0031] Working Principle: When starting work, to align the saw blades, the spacing needs to be adjusted according to the blade size. First, pull the locking rod 52 to the left to release the locking state between the locking rod 52 and the base 1. Then, rotate the rotating disk 51. The rotating disk 51 drives the transmission shaft 5 to rotate synchronously. The transmission shaft 5 drives the intermediate sprocket 6 to rotate synchronously. The intermediate sprocket 6 drives the other two sprockets 6 to rotate synchronously via the chain 61. The front and rear sprockets 6 respectively drive the two threaded rods 62 to rotate synchronously. The two threaded rods 62 drive the two threaded connecting blocks 41 to move synchronously to the right. Both connecting blocks 41 drive the sliding blocks 4 to move synchronously to the right. To move the sliding blocks 4 to the left, simply rotate the rotating disk 51 in the opposite direction. As described above, the two threaded rods 62 will drive the two connecting blocks 41 to move synchronously to the left. Continue turning and moving to the left. The two connecting blocks 41 will drive the sliding block 4 to move synchronously to the left. After the spacing is adjusted, the worker pushes the locking rod 52 to the right. The right end of the locking rod 52 moves into the base 1, where the locking rod 52 locks with the base 1, and the rotating disk 51 cannot rotate. Then, the motor 2 is started, and the motor 2 drives the conveyor shaft 12 to rotate. The conveyor shaft 12 drives the conveyor belt 15 to move synchronously. After placing the saw blade on the upper side of the conveyor belt 15, the conveyor belt 15 will drive the saw blade to move backward. During the movement, the saw blade will encounter the inclined surface of the fixed block 3. Then, the saw blade will move along the inclined surface while adjusting its direction. When the saw blade moves from the inclined surface to the straight surface, the straight surface on the left side of the fixed block 3 and the straight surface on the right side of the sliding block 4 will make the saw blade move in a straight line. All the saw blades that pass by will move in a straight line, thus automatically aligning the saw blade.

[0032] When starting work, the saw blade is usually coated with anti-rust oil to ensure long-term storage. The anti-rust oil is used to prevent the saw blade from oxidizing and rusting. When the alignment device aligns the saw blade, the anti-rust oil will adhere to the outer surface of the conveyor belt 15. The anti-rust oil adhering to the conveyor belt 15 will cause dust and debris to adhere to it. After dust and debris adhere to the outer surface of the conveyor belt 15, the saw blade will tilt when placed on it and will no longer be horizontal, which will lead to a decrease in the alignment quality. When the alignment device is started, the conveyor belt 15 will move. At this time, the scraper on the upper side of the cleaning block 72 will scrape off the dust, debris and anti-rust oil adhering to the outer surface of the conveyor belt 15. These debris that affect the horizontality of the saw blade will fall into the interior of the debris collection box 7 along the cleaning block 72. When the debris collection box 7 needs to be cleaned, simply pull the handle 71 to the right to remove the debris collection box 7 from the interior of the base 1. After emptying the debris inside the debris collection box 7, it can be reinstalled into the interior of the base 1.
