The present application has the effect of simplifying the process of disassembling and assembling the cutter and facilitating quick replacement of the cutting tool.

[0004] At present, after the slitting blades on the slitting machine have been working for a period of time, it is usually necessary to regularly inspect the slitting blades to prevent the slitting blades from being damaged or blunted. For example, although the patented part is slid into place through the installation sleeve, it is still necessary to fasten the cutters one by one with the fastening screws when installing them. Moreover, when the cutters are replaced and installed, the number of cutters installed on the driven shaft is large, and the number of fastening screws is large. Therefore, the process of disassembling and assembling the cutters is relatively cumbersome, time-consuming and labor-intensive. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example:

[0031] like Figure 1 and Figure 2 、 3 As shown in , the solution of this embodiment provides a quick-changing device for cutting tools of an automatic slitting machine, comprising a rotating roller 1 and a cutter 3. The outer peripheral wall of the rotating roller 1 is provided with a chute 101 parallel to the central axis of the rotating roller 1, the chute 101 being arranged in a ring array with the central axis of the rotating roller 1 as the center, and a retractable stop block 4. A rack 102 is provided in the chute 101, and the cutter 3 is relatively fixed between two adjacent stop blocks 4 during use;

[0032] The cutter 3 is arranged on the rotating roller 1, and the cutter 3 includes a sleeve 301 and a cutter 3. The cutter 3 is fixedly connected to the sleeve 301. The sleeve 301 is sleeved on the rotating roller 1. When in use, the sleeve 301 is fixed by sliding it between the two blocks 4. A limiting plug-in 303 corresponding to the rack 102 is provided on the sleeve 301. The limiting plug-in 303 is used in conjunction with the rack 102. After the tool is installed, locking members 2 are provided at both ends of the rotating roller 1 to fix it. Specifically, Figure 4 、 5 As shown in .

[0033] It should be further explained that the number of the chute 101 is at least 2, and the rack 102 is provided in the chute 101, and the rack 102 cooperates with the insertion end 3032 of the limiting plug 303 to facilitate the movement of the sleeve 301 of the cutter 3 in one direction. Figure 5 and Figure 4 As shown in .

[0034] It needs to be further explained that, Figure 5 As shown in the figure, the sliding sleeve 301 is provided with upper and lower through-holes 302, the middle part of the hole 302 has a movable cavity 3021, the insertion end 3032 of the limiting plug-in 303 passes through the hole 302 and cooperates with the rack 102, and the middle and lower part of the limiting plug-in 303 has a limiting block 3031 that can move up and down in the movable cavity 3021, and a first return spring 304 is provided between the upper part of the limiting block 3031 and the movable cavity, and the first return spring 304 is sleeved on the body of the limiting plug-in 303. During use, the limiting plug-in 303 can always face the axial direction, and the limiting plug-in 303 is only moved outward when sliding.

[0035] It should be further explained that a groove 103 is provided between the two slide grooves 101, the block 4 is hinged to the opening of the groove 103, and a second return spring 6 is provided in the groove 103, one end of the second return spring 6 is fixedly connected to the block 4, and the other end of the second return spring 6 is fixedly connected to the bottom of the groove 103. During use, the sliding of the sleeve 301 presses the block 4 into the groove 103. After the sleeve 301 slides over, the block 4 is pushed out again under the action of the second return spring 6, thereby forming a block against the sleeve 301 to prevent the sleeve 301 from being displaced, and at the same time, the limit plug-in 303 and the rack 102 are cooperated to fix the tool.

[0036] It should be further explained that the cross section of the stop block 4 is a right triangle with an inclined surface. The inclined surface is used to facilitate the movement of the sleeve 301, and the right angle side is used to facilitate the fixing of the sleeve 301. Figure 6 、 7 and Figure 8 As shown in .

[0037] It should be further explained that the insertion end 3032 of the limiting plug 303 has an inclined surface corresponding to the rack 102. The function of the inclined surface is to facilitate the movement of the sleeve, and the right angle side is to limit and fix the sliding sleeve 301. Figure 4 and Figure 5 As shown in .

[0038] It should be further explained that the bottom of the stop block 4 has a protruding limiting plate 5, and the limiting plate 5 is fixedly connected to the stop block 4. The purpose of the limiting plate 5 is to prevent the stop block 4 from excessively popping out of the groove 103. It should also be explained that this type of limiting structure is a conventional existing structure and will not be repeated here.

[0039] It needs to be further explained that, Figure 9 As shown in , the upper end of the limiting plug 303 is provided with a fixing sleeve 7 with a side opening, and the fixing sleeve 7 is used to fix the limiting plug 303. When the limiting plug 303 is pulled out, the fixing sleeve 7 is sleeved on the upward displacement part of the limiting plug 303 to prevent the limiting plug 303 from sliding downward, so as to avoid the limiting plug 303 always being supported by hand.

[0040] Working principle of this utility model:

[0041] When the tool 3 is in the working state, the tool 3 is fixed to the workbench 301 by pressing the stopper 303 on the workbench 301 and the stopper 303 on the workbench 301.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is 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 can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
