[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 The present invention provides an embodiment of a novel slitting knife device, comprising a first fixing block 1 and a second fixing block 3. The second fixing block 3 is disposed above the first fixing block 1. Fixing baffles 2 are installed on both sides of the first fixing block 1 and the second fixing block 3. A reserved hole 8 is provided at the center of the interior of the first fixing block 1. First knife grooves 9 are opened on both sides of the interior of the first fixing block 1. A slitting knife body 6 is installed inside the first knife grooves 9. Second knife grooves 10 are opened on both sides of the interior of the second fixing block 3. Mounting holes 11 are opened inside the fixing baffles 2. Fixing screws 5 are provided inside the mounting holes 11. Limit nuts 4 are provided outside the fixing screws 5. The width of the first fixing block 1 and the second fixing block 3 are the same. The slitting blade body 6 is provided in two sets, and the slitting blade body 6 passes through the interior of the first blade groove 9 and the second blade groove 10 respectively. Specifically, such as Figure 1 and Figure 2 As shown, the slitting blade body 6 is first inserted into the blade groove of the first fixing block 1 and the second fixing block 3. Then, the fixing baffle 2 is attached to both sides of the first fixing block 1 and the second fixing block 3. Then, the fixing screw 5 is used to pass through the fixing baffle 2 and be embedded in the inside of the slitting blade body 6 to limit and fix it. The fixing baffle 2, the first blade groove 9 and the second blade groove 10 provide stable support and limit the position of the slitting blade for the cutting distance of the slitting blade body 6. The thickness of the slitting blade is increased and the amount of the slitting blade head protrusion is reduced, so that the slitting blade can maintain stability in the slitting process when slitting the plastic.

[0018] The fixing screw 5 is threaded into the mounting hole 11. The first fixing block 1 and the second fixing block 3 are both provided with threaded grooves. The fixing screw 5 is threaded into the threaded grooves of the first fixing block 1 and the second fixing block 3. Specifically, such as Figure 1 and Figure 5 As shown, the increased thickness of the slitting blade body 6 enhances durability and extends the replacement interval. When the slitting blade body 6 needs to be replaced, simply rotate the fixing screw 5 to remove it from the fixing baffle 2 and pull the slitting blade body 6 out of the blade groove.

[0019] The front end of the first fixing block 1 is provided with a socket 7, and the socket 7 is provided with a threaded groove and passes through the reserved hole 8; Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, during installation, the reserved hole 8 on the first fixing block 1 is inserted into the horizontal axis of the slitting, and then it can be fixed on the horizontal axis of the slitting by bolts passing through the insertion hole 7. The slitting blade of this slitting device can be effectively fixed. The position of the slitting blade and the working distance should be adjusted before production.

[0020] Working principle: First, the corresponding slitting blade body 6 needs to be installed inside the first fixing block 1 and the second fixing block 3. Increasing the thickness of the slitting blade body 6 enhances durability and extends the replacement interval. When the slitting blade body 6 needs to be replaced, simply rotate the fixing screw 5 to remove it from the fixing baffle 2 and pull the slitting blade body 6 out of the blade groove. Insert the slitting blade body 6 into the blade groove of the first fixing block 1 and the second fixing block 3. Then, attach the fixing baffle 2 to both sides of the first fixing block 1 and the second fixing block 3. Then, use the fixing screw 5 to penetrate the fixing baffle 2 and embed it inside the slitting blade body 6 to limit and fix it. The fixing baffle 2, the first blade groove 9 and the second blade groove 10 provide stable support and limit the slitting blade position for the cutting spacing of the slitting blade body 6. Increasing the thickness of the slitting blade blade reduces the amount of the slitting blade head protrusion, so that the slitting blade maintains stability during the slitting process when slitting the shaped glue.
