[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example

[0035] The present invention will now be further described with reference to the accompanying drawings.

[0036] like Figures 1-6 As shown, the saw blade heat treatment self-weight leveling machine provided in this embodiment includes:

[0037] The machine body 1 has two sets of upper and lower conveyor belt assemblies and two sets of upper and lower pressure roller assemblies connected inside the machine body 1. A channel for the saw blade to pass through is provided between the upper and lower conveyor belt assemblies. The pressure roller assembly is pressed against the back side of the two sets of conveyor belt assemblies, and the upper pressure roller assembly is slidably set on the machine body 1.

[0038] The exhaust gas treatment box 3 is detachably connected to the top of the body 1, and the air inlet of the exhaust gas treatment box 3 is connected to the inside of the body 1.

[0039] The working principle and beneficial effects of this utility model are as follows:

[0040] The saw blade heat treatment self-weight leveling machine provided in this embodiment places the heat-treated saw blade from one side of the leveling machine into the channel between two sets of conveyor belt assemblies. The upper and lower sets of conveyor assemblies operate synchronously, driving the saw blade to move forward smoothly. The lower pressure roller assembly abuts against the lower mesh belt assembly, and the upper pressure roller assembly slides along the vertical direction of the machine body 1. The machine body 1 is provided with a vertical groove adapted to the upper pressure roller assembly. Under the action of gravity, the upper pressure roller assembly abuts against the mesh belt assembly, which can accommodate saw blades of different thicknesses. During the leveling process, the exhaust gas generated in the machine body 1 during the leveling process is drawn upward through the exhaust gas treatment box 3, treated, and then discharged outward.

[0041] Through the above structural design, during the movement of the saw blade, the pressure of the upper and lower pressure rollers causes the saw blade to undergo slight deformation, eliminating the flatness deviation caused by heat treatment and achieving a leveling effect. The upper pressure roller assembly applies pressure to the saw blade under its own weight, which can maintain continuous and stable pressure and can adapt to saw blades of different thicknesses. The matching exhaust gas treatment box 3 can capture and treat the exhaust gas generated by the heat treatment and leveling of the saw blade in a timely manner, avoiding the direct discharge of exhaust gas into the workshop environment and improving the environmental performance of the saw blade leveling process.

[0042] In one embodiment, the conveyor belt assembly includes: a conveyor belt drive assembly 4, a drive roller, a driven roller, and a conveyor belt 2. The drive roller and the driven roller are rotatably connected to both ends of the machine body 1, respectively. The conveyor belt 2 is wound around the drive roller and the driven roller. The conveyor belt drive assembly 4 is installed at the top of one end of the machine body 1, and the output end of the conveyor belt drive assembly 4 is connected to the drive rollers of the two sets of conveyor belt assemblies.

[0043] The working principle and beneficial effects of the above technical solution are as follows:

[0044] When using the conveyor belt assembly, start the conveyor belt drive assembly 4. The conveyor belt drive assembly 4 can be set as a combination of a motor and a reducer. The conveyor belt drive assembly 4 drives the active rollers of the two sets of conveyor belt assemblies to rotate. The active rollers drive the conveyor belt 2 to move. The driven rollers rotate accordingly and provide auxiliary support for the conveyor belt 2. The upper and lower conveyor belts 2 move while clamping the saw blade and feeding it forward.

[0045] In one embodiment, tensioning components are provided on both sides of the other end of the body 1, and the tensioning components include:

[0046] Slide 5 is horizontally set on the side wall of the machine body 1;

[0047] Driven roller seat 6 is slidably connected to the slide groove 5, and driven roller shaft is rotatably connected to the driven roller seat 6. A collar 8 is provided at one end of the driven roller seat 6.

[0048] Tensioning screw 7 is rotatably connected to the side wall of machine body 1. Tensioning screw 7 is aligned with the length direction of slide groove 5. One end of tensioning screw 7 is rotatably connected to collar 8.

[0049] Screw sleeve 9 is rotatably connected to machine body 1 and screwed to tension screw 7;

[0050] The guide slide rail 10 has two guide slide rails 10 symmetrically connected to the upper and lower sides of the slide groove 5. The driven roller seat 6 has guide grooves 11 on the upper and lower sides, and the guide grooves 11 are slidably connected to the guide slide rail 10.

[0051] The working principle and beneficial effects of the above technical solution are as follows:

[0052] When the tensioning assembly is in use, rotating the screw sleeve 9 causes threaded transmission between the screw sleeve 9 and the tensioning screw 7. Since the screw sleeve 9 is mounted on the machine body 1 and can only rotate, it drives the tensioning screw 7 to move horizontally. The end of the tensioning screw 7 is engaged in the collar 8 and rotates. Therefore, the tensioning screw 7 drives the driven roller seat 6 to move horizontally, and the driven roller moves away from the driving roller, thus tensioning the conveyor belt 2. The guide rail 10 guides the driven roller seat 6.

[0053] In one embodiment, the tensioning component further includes:

[0054] Vertical plate 21, vertical plate 21 is connected to the body 1 and arranged near the screw sleeve 9;

[0055] Limiting rod 22 is slidably connected to the upright plate 21. The axis of limiting rod 22 is perpendicular to the axis of tensioning screw 7. A spring 24 is sleeved on the limiting rod 22.

[0056] The limiting plate 23 is connected to the end of the limiting rod 22. The two ends of the spring 24 abut against the limiting plate 23 and the upright plate 21 respectively. The limiting plate 23 is set as an arc plate, and the side of the limiting plate 23 near the threaded sleeve 9 is provided with a first limiting tooth, and the outer wall of the threaded sleeve 9 is provided with a corresponding second limiting tooth. The limiting plate 23 is pressed onto the threaded sleeve 9, and the first limiting tooth and the second limiting tooth are engaged.

[0057] The working principle and beneficial effects of the above technical solution are as follows:

[0058] When using the tensioning assembly, pull the end of the limiting rod 22 outward while compressing the spring 24 to store energy, so that the limiting plate 23 separates from the screw sleeve 9, allowing the screw sleeve 9 to rotate freely for adjustment; after tensioning is completed, release the limiting rod 22, and under the elastic force of the spring 24, the limiting plate 23 returns to its original position and contacts the screw sleeve 9, and the first limiting tooth and the second limiting tooth re-engage, limiting the screw sleeve 9 again, preventing the screw sleeve 9 from rotating and shifting during the use of the leveling machine, which would affect the tension on the conveyor belt 2.

[0059] In one embodiment, an exhaust fan 12 is provided at the top air outlet of the exhaust gas treatment box 3 to draw the exhaust gas inside the machine body 1 upward and discharge it.

[0060] The exhaust gas treatment box 3 is equipped with a filter plate and an adsorption plate arranged from bottom to top; the filter plate is a porous filter screen plate, and the adsorption plate includes any one or more of the following: activated carbon layer, zeolite layer, and silica gel adsorption layer.

[0061] The working principle and beneficial effects of the above technical solution are as follows:

[0062] When the exhaust fan 12 on the exhaust gas treatment box 3 is started, it generates an upward suction force on the exhaust gas, causing the exhaust gas to flow upward and pass through the filter plate and adsorption plate in sequence. The filter plate filters out large particulate impurities mixed in the exhaust gas. The adsorption plate is set with a multi-layer adsorption structure. The adsorption layer adopts any one or more combinations of activated carbon layer, zeolite layer, and silica gel adsorption layer to effectively adsorb some pollutants in the exhaust gas and improve the purification effect of flue gas.

[0063] In one embodiment, the upper pressure roller assembly includes a plurality of equally spaced upper pressure rollers 14, which are slidably connected to the machine body 1; the lower pressure roller assembly includes a plurality of equally spaced lower pressure rollers 15 and a pressure roller drive assembly 13, which are rotatably connected to the machine body 1; the pressure roller drive assembly 13 is connected to the top of the machine body 1 and is connected to the shaft of the lower pressure rollers 15 via a transmission chain; the upper pressure rollers 14 and the lower pressure rollers 15 respectively abut against the upper and lower sets of conveyor belts 2.

[0064] The upper pressure roller 14 and the lower pressure roller 15 are arranged alternately, and the distance L1 between adjacent upper pressure rollers 14 is equal to the distance L2 between adjacent lower pressure rollers 15.

[0065] The working principle and beneficial effects of the above technical solution are as follows:

[0066] The upper pressure roller presses against the conveyor belt 2 under gravity, and the machine body 1 is equipped with a vertical groove adapted to the upper pressure roller 14. When the lower pressure roller assembly is in use, the pressure roller drive assembly 13 is activated, driving the lower pressure roller 15 shaft to rotate via a transmission chain. The lower pressure roller 15 presses against the bottom of the conveyor belt 2, assisting in the feeding of the conveyor belt 2 while ensuring pressure on the underside of the saw blade. The upper pressure roller 14 and lower pressure roller 15 are arranged alternately, which, compared to a direct vertical arrangement, improves the uniformity of force on the saw blade surface and provides better leveling and stretching effects.
