An aluminum strip is provided above the base, and the two ends of the aluminum strip are respectively fixed on the outer walls of the two rotating shafts.

[0004] The above patent records an aluminum strip slitting machine. During the slitting process, if the aluminum strip is in a loose state, it is difficult to keep the aluminum strip stable during the cutting process, and it is more likely to vibrate and deflect. The aluminum strip is prone to curling due to uneven cutting quality. The slitting mechanism of the slitting machine can be further improved to solve the above problems. Utility Model Content

[0007] Preferably, when the spring telescopic rod is in a natural state, the height of the tensioning roller is lower than the height of the cutter.

[0008] Preferably, the gear set and the tensioning roller are connected in transmission via a ratchet shaft.

[0009] Preferably, the outer surface of the tensioning roller is covered with a rubber roller cover.

[0010] Preferably, the length of the tension roller is at least 80% of the length of the cutter.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model provides a tensioning mechanism at the front and rear parts of the knife seat, and controls the knife seat to move downward through the slitting machine. Since the tensioning roller is below the cutter, the tensioning roller will contact the surface of the aluminum strip before the cutter, and then the tensioning roller will press on the aluminum strip and stop moving, while the cutter continues to move downward. During this process, the spring telescopic rod is forced to contract, and at the same time the rack moves downward and drives the gear set to rotate, and then the gear set drives the tensioning roller to rotate, so that the tensioning rollers on the front and rear sides of the cutter are turned outward, thereby tensioning the part of the aluminum strip to be cut, ensuring that the aluminum strip can remain stable during the slitting process by the cutter, and is less likely to vibrate and deflect during cutting, further improving the cutting accuracy and quality, and less likely to cause curling of the aluminum strip due to uneven cutting quality.

[0019] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0020] See also Figure 1-4 The utility model provides an aluminum strip slitting mechanism for preventing curling, comprising a knife holder 1, a cutter 2 and a tensioning mechanism 3. The cutter 2 is assembled at the bottom of the knife holder 1, and the tensioning mechanism 3 is provided at the front and rear parts of the knife holder 1.

[0021] The utility model provides an aluminum strip slitting mechanism that prevents curling. The tensioning mechanism 3 includes a mounting frame 31, a spring telescopic rod 32, a roller seat 33, a tensioning roller 34, a gear set 35 and a rack 36. The front and rear parts of the knife seat 1 are screwed with the mounting frame 31, and at least two spring telescopic rods 32 are equidistantly installed on the middle part of the mounting frame 31. The spring telescopic rod 32 is longitudinally arranged, and the bottom end of the spring telescopic rod 32 is screwed to the roller seat 33. The tensioning roller 34 is rotatably installed on the inner side of the roller seat 33, and the cutter 2 is centered between the front and rear tensioning rollers 34. The left and right side walls of the roller seat 33 are rotatably installed with gear sets 35. The roller shafts at both ends of the tensioning roller 34 are transmission-connected to the gear set 35. The gear set 35 can drive the tensioning roller 34 to rotate. Racks 36 are symmetrically welded on the left and right ends of the mounting frame 31. The rack 36 is longitudinally arranged and meshes with the top gear in the gear set 35.

[0022] To further illustrate, when the spring telescopic rod 32 is in a natural state, the height of the tensioning roller 34 is lower than that of the cutter 2, so as to ensure that the tensioning roller 34 can contact the aluminum strip before the cutter 2 to tension it.

[0023] Further explanation: the gear set 35 and the tensioning roller 34 are connected by a ratchet shaft, so that the gear set 35 can only drive the tensioning roller 34 to rotate in one direction, to prevent the tensioning roller 34 from rotating and resetting when the cutter 2 moves up and resets, causing the aluminum strip to be pushed to an offset position.

[0024] To further illustrate, the outer surface of the tensioning roller 34 is covered with a rubber roller cover 341 , which can enhance the friction between the tensioning roller 34 and the surface of the aluminum strip, thereby ensuring the tensioning effect.

[0025] It is further explained that the length of the tensioning roller 34 is at least 80% of the length of the cutter 2 to ensure the tensioning effect.

[0026] Further explanation: shell covers 37 are installed on the left and right side walls of the roller seat 33, the gear set 35 is located on the inner side of the shell cover 37, and the rack 36 passes through the top opening of the shell cover 37 to engage with the gear set 35. The shell cover 37 can provide airtight protection for the gear set 35 to ensure that the gear set 35 runs smoothly and is not prone to jamming.

[0027] Here’s how it works:

[0028] First, install the knife holder 1 back to the tool station of the slitting machine. When the aluminum strip cutting action is performed, the slitting machine controls the knife holder 1 to move downward. Since the tensioning roller 34 is below the cutter 2, the tensioning roller 34 will contact the surface of the aluminum strip before the cutter 2. Then the tensioning roller 34 presses on the aluminum strip and stops moving, while the cutter 2 continues to move downward. During this process, the spring telescopic rod 32 is forced to shrink, and at the same time the rack 36 moves downward and drives the gear set 35 to rotate, and then the gear set 35 drives the tensioning roller 34 to rotate, so that the tensioning rollers 34 on the front and rear sides of the cutter 2 are flipped outward, thereby tensioning the part of the aluminum strip to be cut, ensuring that the aluminum strip can remain stable during the slitting process by the cutter 2, and is less likely to vibrate and deflect during cutting, further improving the cutting accuracy and quality, and less likely to cause curling of the aluminum strip due to uneven cutting quality.

[0029] Secondly, by providing a rubber roller cover 341 on the outer surface of the tensioning roller 34 , the rubber roller cover 341 can enhance the friction between the tensioning roller 34 and the surface of the aluminum strip, thereby ensuring the tensioning effect.

[0030] Third, by installing shell covers 37 on both the left and right side walls of the roller seat 33, the shell covers 37 can provide airtight protection for the gear set 35, ensuring that the gear set 35 runs smoothly and is not prone to jamming.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
