The cam drive mechanism 200 is used to drive the cutting mechanism 300 to perform reciprocating up and down movements. The cutting mechanism 300 includes a cutting knife 301 and a clamping column 302 clamped on the cam drive mechanism 200 arranged on the frame 100. A pressure knife plate 303 is inserted on the clamping column 302. A knife hanging rod 304 is arranged on the frame 100. A pin hole 305 adapted to the knife hanging rod 304 is opened on the cutting knife 301. The pressure knife plate 303 is provided with a locking bolt 306, and a threaded hole adapted to the locking bolt 306 is arranged on the cutting knife 301. The present utility model can realize the quick disassembly and installation operations of the cutting knife 301 through the cutting mechanism 300 detachably arranged on the cam drive mechanism 200, greatly improving the disassembly and replacement efficiency of the cutting knife 301, and solving the problem that the cutting knife 301 of the traditional slitting mechanism of a slitter is usually welded or integrally formed with the tool body, and its installation position is fixed. This leads to trouble in operation when the cutting knife 301 needs to be disassembled, repaired or replaced during the use of the cutting knife 301, greatly reducing the replacement and repair efficiency of the cutting knife 301 and the cutting efficiency of the slitter.
[0022] According to an embodiment of the present utility model, as Figures 1 - 3 shown, there are two clamping columns 302, which are respectively located on the left and right sides of the pressure knife plate 303. The clamping column 302 is provided with a clamping groove. The present utility model can realize the pressing operation of the pre-installed cutting knife 301 by inserting the clamping column 302 on the pressure knife plate 303 into the cam drive mechanism 200, and it is convenient to realize the quick pulling out operation of the pressure knife plate 303 during the disassembly operation, facilitating the quick disassembly operation of the pressure knife plate 303, and the operation is more convenient.
[0023] According to another embodiment of the present utility model, as Figure 1 and Figure 2 shown, a plurality of lightening holes 400 are formed in the pressing blade plate 303. The present utility model can reduce the weight of the pressing blade plate 303 through the lightening holes 400, facilitating the operator to hold the pressing blade plate 303 for installation and disassembly, which is more labor-saving.
[0024] According to another embodiment of the present utility model, as Figure 1 and Figure 3 shown, a guiding hole 500 is formed in the pressing blade plate 303. The present utility model can guide and limit the installation direction of the pressing blade plate 303 through the guiding hole 500, facilitating the quick positioning and installation operation of the pressing blade plate 303.
[0025] A handle 600 is arranged on the upper part of the pressing blade plate 303. The present utility model can realize the taking operation of the pressing blade plate 303 by the operator holding the handle 600, and the operation is more convenient.
[0026] A sliding block is arranged on the tool hanging rod 304, a sliding groove is formed in the pressing blade plate 303, and the sliding block is slidably arranged in the sliding groove. The other end of the tool hanging rod 304 is clamped on the machine frame 100. The present utility model can realize the guiding and limiting operation during the up and down movement of the tool hanging rod 304 driving the sliding block and the pressing blade plate 303 driving the pressing blade under the action of the cam transmission mechanism 200 through the connection between the tool hanging rod 304 and the sliding block and the guiding and limiting action of the sliding groove on the sliding block, and the operation is more convenient.
[0027] The using method of the present utility model:
[0028] First of all, it should be clear that the slitting mechanism involved in the present utility model is mainly used for setting on a slitter for cutting cardboard. The present utility model takes the operation when the cutting tool 301 is damaged and needs to be replaced during the cutting operation of the cutting mechanism 300 as an example to elaborate on its usage method in detail. When the cutting tool 301 needs to be disassembled and replaced, the operator first removes the locking bolt 306 with the help of a wrench, and then the operator holds the handle and pulls out the pressure blade plate 303 outward. Then the operator grabs the cutting tool 301 and pulls it out from the tool hanging rod 304. Then the operator can perform maintenance operations on the cutting tool 301. At the same time, the operator aligns the pin hole 305 on the new cutting tool 301 with the tool hanging rod 304 and inserts it. At the same time, the clamping post 302 on the pressure blade plate 303 corresponds to the clamping hole on the cam drive mechanism 200. Then the operator holds the pressure blade plate 303 and inserts the guiding hole 500 on the pressure blade plate 303 into the pin rod on the cam guiding mechanism. Then the operator tightens the locking bolt 306 until the pressure blade plate 303 presses the cutting tool 301 tightly, and the rapid installation and fixation operation of the cutting tool 301 can be realized. The present utility model can realize the rapid disassembly and installation operations of the cutting tool 301 through the cutting mechanism 300 detachably arranged on the cam drive mechanism 200, greatly improving the disassembly and replacement efficiency of the cutting tool 301, and solving the problem that the cutting tool 301 of the traditional slitting mechanism for a slitter is usually welded or integrally formed with the tool body, and its installation position is fixed. This leads to the trouble in operation when the cutting tool 301 needs to be disassembled, repaired or replaced during the use of the cutting tool 301, greatly reducing the replacement and repair efficiency of the cutting tool 301 and the cutting efficiency of the slitter.
[0029] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0030] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
