[0037] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a convertible cutting material support device of this utility model.

[0038] like Figures 1-8 As shown, a convertible cutting material support device of this utility model includes a base frame 1. A limit plate 12 and a bullseye universal bearing 13 are fixedly installed at the bottom of the base frame 1. A lead screw 3 is rotatably installed inside the base frame 1. A connecting rod 2 is movably arranged on the lead screw 3. A support plate 21 is rotatably connected to the connecting rod 2. A movable mounting plate 22 is hinged to one end of the support plate 21. The lower end of the movable mounting plate 22 is rotatably installed inside the base frame 1.

[0039] Mounting frame 4 is rotatably mounted on the upper end of movable mounting plate 22. Flat roller 5 and V-shaped roller 6 are rotatably mounted inside the mounting frame 4. Insertion holes 41 are provided at both ends of the mounting frame 4.

[0040] Positioning pin 7 is inserted into the movable mounting plate 22 and is used to fix the flat idler roller 5 and the V-shaped idler roller 6 after their positions are changed.

[0041] In this application, bullseye universal bearings 13 are provided at the four corners of the bottom of the base frame 1, and limit plates 12 are provided on both sides of the bottom. The limit plates 12 are L-shaped. The material support frame is supported by 80*80mm angle iron as the base and 60*6mm flat iron and φ16mm round steel. The limit plates 12 and bullseye universal bearings 13 cooperate to achieve sliding limit, ensuring that the material support device moves smoothly without derailing. The universal bearings reduce frictional resistance and improve the smoothness of the device movement.

[0042] Mounting frame 4 rotates on upper mounting rod 24 via sleeve rod 42, and with the insertion hole 41, it realizes the interchange of two types of idlers, quickly switching between flat or curved support modes. For example, when cutting a large number of materials such as angle iron, flat iron, and square steel, the movable idler frame can be adjusted to flat wheel and fixed. When cutting a large number of round materials such as round pipe and round steel, the positioning pin 7 can be removed, the mounting frame 4 can be rotated until the V-shaped idler 6 faces upward, and then the positioning pin 7 can be inserted to make the V-shaped groove automatically center the round material, and the flat support surface ensures stable conveying of the profile.

[0043] One end of the lead screw 3 is rotatably sleeved in the mounting base 31, and a handle 32 is fixedly connected to the end. The other end is fixedly installed on the fixing plate 35. The mounting base 31 is snapped into one end of the base frame 1. The fixing plate 35 is fixedly installed inside the base frame 1. A dustproof plate 36 for dust protection of the lead screw 3 is fixedly connected to the upper end of the fixing plate 35. A nut 34 is threaded on the lead screw 3 and is fixedly installed in the movable block 33.

[0044] Rotating the handle 32 drives the lead screw 3 to rotate. Through the threaded engagement between the lead screw 3 and the nut 34, the movable block 33 and the connecting rod 2 move linearly along the lead screw 3. The dustproof plate 36 is set above the lead screw 3. The dustproof plate 36 is triangular. During the cutting process, the flying debris falls on the surface of the dustproof plate 36 and slides down along the inclined surface of the dustproof plate 36, which can effectively prevent the debris from falling into the thread groove of the lead screw 3 and affecting the engagement between the lead screw 3 and the nut 34.

[0045] The movable block 33 is fixedly connected to the connecting rods 2 on both sides. The connecting rods 2 are rotatably mounted on the movable rod 26. The support plate 21 is fixedly mounted on the movable rod 26. Movable grooves 11 for the movement of the movable rod 26 are provided on both sides of the base frame 1.

[0046] When the movable block 33 drives the connecting rod 2 to move away from the handle 32, the connecting rod 2 pushes the support plate 21 to rotate around the movable rod 26, causing the end of the support plate 21 near the middle mounting rod 23 to rise, thereby causing the movable mounting plate 22 near the mounting frame 4 to rise. Conversely, it will fall, thereby adjusting the height of the supported material to achieve the ideal working height.

[0047] A lower mounting rod 25 is fixedly installed at one end inside the base frame 1. The end of the movable mounting plate 22 away from the mounting frame 4 is rotatably mounted on the lower mounting rod 25. A middle mounting rod 23 is fixedly connected to the end of the support plate 21 away from the connecting rod 2. The middle part of the movable mounting plate 22 is rotatably mounted on the middle mounting rod 23. An upper mounting rod 24 is fixedly connected to the upper end of the movable mounting plate 22. A sleeve rod 42 is fixedly connected to the middle of the mounting frame 4. The sleeve rod 42 is rotatably mounted on the upper mounting rod 24. Stops 27 are provided at both ends of the middle mounting rod 23, the upper mounting rod 24, and the movable rod 26.

[0048] The two ends of the support plate 21 are hinged to the movable mounting plate 22 and the connecting rod 2 via the middle mounting rod 23 and the movable rod 26, respectively. The two ends of the movable mounting plate 22 are hinged to the mounting frame 4 and the base frame 1 via the upper mounting rod 24 and the lower mounting rod 25, respectively. The connecting rod 2 and the movable rod 26 can move along the movable groove 11. By setting the stop block 27, the hinge point can be prevented from coming out. The multi-plate linkage is driven by the rotation of the screw 3 to realize the adjustment of the material support height.

[0049] A pull ring 71 is fixedly connected to one end of the positioning pin 7. A limit groove 72 is opened on the positioning pin 7. A limit mechanism 8 is provided on the movable mounting plate 22. The limit mechanism 8 includes a fixing block 81, which is fixedly installed on the movable mounting plate 22. A fixing shaft 83 is fixedly installed on the fixing block 81. A lever 85 is fixedly connected to the middle rod of the fixing shaft 83. Limit arms 84 are rotatably connected to both ends of the rod of the fixing shaft 83. The limit arms 84 are connected to the fixing block 81 by a torsion spring 82. The end of the limit arm 84 away from the fixing shaft 83 is engaged in the limit groove 72.

[0050] When switching rollers, pressing down the lever 85 raises the limiting arm 84 upwards. Rotating the mounting bracket 4 aligns the insertion hole 41 at one end with the hole on the movable mounting plate 22. Then, the positioning pin 7 is inserted into the mounting bracket 4 and the movable mounting plate 22. Releasing the lever 85 causes the limiting arm 84 to rotate downwards around the fixed shaft 83 under the action of the torsion spring 82, locking onto the limiting groove 72. This limits the positioning pin 7, preventing it from moving or falling off due to equipment vibration during the cutting process, thus improving stability and reliability.

[0051] Working principle of a convertible cutting material support device:

[0052] The device drives the lead screw 3 to rotate by turning the handle 32, which in turn drives the movable block 33 to move along the axial direction of the lead screw 3. The movable block 33 drives the support plate 21 to rotate around the movable rod 26 through the connecting rod 2. The movable mounting plate 22 is linked by the central mounting rod 23 to form a linkage motion, which ultimately drives the mounting frame 4 to complete the height adjustment. When changing the idler roller, first press down the dial 85 to lift the end of the limiting arm 84 away from the fixed shaft 83 upward. Then pull out the positioning pin 7, manually flip the mounting frame 4 so that the target idler roller faces upward, insert the positioning pin 7 into the insertion hole 41, release the dial 85, and the limiting arm 84 will automatically lock into the limiting groove 72 under the action of the torsion spring 82.

[0053] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
