[0018] Figure 2 This is a schematic diagram of the slitting blade installation structure of the aluminum sheet and strip slitting device of this utility model. Detailed Implementation

[0019] The aluminum sheet and strip slitting device of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0020] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0021] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes an aluminum sheet and strip slitting device, including a slitting shaft 1, a slitting blade 2, and a positioning transmission component.

[0022] Specifically, the slitting blade 2 is provided in multiple sets, and the slitting blade 2 is detachably mounted on the slitting shaft 1.

[0023] The positioning transmission component is disposed on the slitting shaft 1, and the positioning transmission component is used to position and drive the slitting blade 2.

[0024] The positioning transmission component includes a positioning disk 3, a positioning shaft 4, and a fixing knob 5. There are two positioning disks 3, which are distributed at both ends of the slitting shaft 1. The positioning shaft 4 is movably disposed between the two positioning disks 3 and passes through the slitting blade 2. The fixing knob 5 is threadedly installed at the end of the positioning shaft 4 and abuts against the outer side of the positioning disk 3.

[0025] In this embodiment, the slitting device is rotatably mounted on the frame and driven by a motor, using the rotation of the slitting blade 2 to slit the aluminum sheet / strip. The method for adjusting the spacing of the slitting blades is as follows:

[0026] The slitting blades 2 are arranged on the slitting shaft 1 according to the slitting width of the aluminum sheet / strip. Then, the positioning shaft 4 passes through all the slitting blades 2 and is fixed between the two positioning discs 3 using a fixing knob 5. The resistance between the slitting blades 2 and the slitting shaft 1 and the positioning shaft 4 allows the slitting blades 2 to be held at a certain position on the slitting shaft 1, enabling rapid adjustment of the slitting width of the aluminum sheet / strip.

[0027] In one specific embodiment, a plurality of positioning plates 6 are evenly spaced and fixedly arranged on the slitting shaft 1, and an installation groove 7 matching the slitting blade 2 is formed between two adjacent positioning plates 6. After the slitting blade 2 is installed in the installation groove 7, the positioning plates 6 can restrict the slitting blade 2 from shifting position along the length direction of the slitting shaft 1, thereby ensuring the consistency of the slitting width of the aluminum sheet and strip.

[0028] In addition, since the positioning plates 6 are evenly arranged on the slitting shaft 1, the distance between the center positions of two adjacent mounting slots 7 is constant. For example, if the distance between the center positions of two adjacent mounting slots 7 is a, and the slitting width of the aluminum strip is 5a, then the slitting blade 2 can be directly and quickly inserted into the mounting slot 7 with a distance of 5 spacing between adjacent slitting blades 2, and the arrangement of the slitting blade 2 can be completed quickly.

[0029] To facilitate the installation of the slitting blade 2 into the mounting slot 7, the outer edge of the positioning piece 6 has a chamfered structure. During installation, the slitting blade 2 can enter the blade mounting slot 7 along the beveled surface of the chamfered structure, making installation of the slitting blade 2 convenient.

[0030] Furthermore, the slitting blade 2 includes two semi-circular blade bodies 8, and the two blade bodies 8 are magnetically connected.

[0031] Specifically, an adsorption magnetic sheet 12 is provided on the connecting end face of the two half-blades 8, and the adsorption magnetic sheet 12 is embedded in the connecting end face of the half-blades 8.

[0032] In this embodiment, during the installation of the slitting blade 2, the two half-blades 8 are inserted into the same mounting slot 7 and assembled together. The magnetic adsorption sheet 12 is used to attract and close the two half-blades 8. Finally, the positioning shaft 4 passes through the two half-blades 8 respectively, and the positioning shaft 4 is fixed using the fixing knob 5, thus completing the installation of the slitting blade 2.

[0033] It should be noted that when multiple slitting blades 2 need to be installed, all slitting blades 2 should be installed into the corresponding mounting slots 7 first, and then the positioning shaft 4 should be inserted through.

[0034] Furthermore, a positioning groove 9 is provided on the connecting end face of the half-blade 8 and the cutting shaft 1, and a positioning block 10 matching the positioning groove 9 is provided on the cutting shaft 1. The positioning block 10 is located between two adjacent positioning pieces 6, and the cross-section of the positioning block 10 is triangular.

[0035] In this embodiment, the cooperation between the positioning block 10 and the positioning groove 9 enables the directional installation of the half-blade 8 onto the cutting shaft 1. In this state, the half-blades 8 located in different mounting grooves 7 can have linearly distributed positioning holes 11. During the fixing process of the half-blade 8, the positioning shaft 4 can be directly inserted through the positioning holes 11 of all the half-blades 8 in a straight line, which facilitates the installation of the positioning shaft 4.

[0036] Compared with the prior art, the present invention has at least the following beneficial effects:

[0037] This utility model arranges the slitting blades according to the slitting spacing, and can be used with positioning and transmission components to position and drive the slitting blades, enabling rapid adjustment of the slitting width of aluminum sheet and strip, greatly improving the efficiency of slitting blade assembly and disassembly, and facilitating on-site adjustment of the slitting blade spacing by operators. It features a simple structure and convenient operation.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
