Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The first embodiment is as follows:

as shown in fig. 1 to 6, a cutter assembly comprises a cutter 2, a cutter disc 3 and a pressing plate 5, wherein the cutter disc 3 is provided with a positioning rod 301, two positioning chutes 303 and two connecting holes 302, and the two connecting holes 302 are provided with internal threads; the pressing plate 5 is provided with second slots 501 corresponding to the two connecting holes 302 respectively, and positioning bosses 502 matched with the two positioning sliding grooves 303 respectively, and the positioning bosses 502 can slide in the positioning sliding grooves 303; two screws 4 respectively penetrate through two second slotted holes 501 on the pressing plate 5 to be in threaded connection with two connecting holes 302 on the cutter head 3 so as to clamp the cutter 2 between the cutter head 3 and the pressing plate 5; a fixing groove 2010 is provided at one end of the cutter 2, and a thrust portion 2020 is provided at the other end opposite to the one end, the fixing groove 2010 is abutted against the positioning rod 301, and the thrust portion 2020 is abutted against the positioning boss 502.

In this embodiment, the fixing groove 2010 includes a first slope surface 202 and a second slope surface 203, the first slope surface 202 and the second slope surface 203 are obliquely crossed to form a clamping end 201 recessed into the cutter 2 body, and the fixing groove 2010 is abutted to the positioning rod 301 through the clamping end 201; the thrust part 2020 comprises a third slope surface 204 and a fourth slope surface 206, the third slope surface 204 and the fourth slope surface 206 are obliquely crossed to form a protruding end 205 protruding out of the cutter 2 body, and the thrust part 2020 abuts against the two positioning bosses 502 through the third slope surface 204 and the fourth slope surface 206 respectively; the upper end surfaces of the two positioning bosses 502 can be made into structures respectively matched with the third slope surface 204 and the fourth slope surface 206, so that the contact area is increased, and the stability and the positioning effect are improved. The first slope surface 202 is parallel to the third slope surface 204; the second slope surface 203 is parallel to the fourth slope surface 206; the clamping end 201 and the protruding end 205 are on the same vertical straight line, and the connecting line of the lowest point of the clamping end 201 and the highest point of the protruding end 205 is parallel to the cutting edge 208 of the cutting knife 2. A half-open first waist-shaped slot 207 corresponding to the connecting hole 302 is arranged on the cutter 2, the opening end of the first waist-shaped slot 207 faces the direction far away from the cutting edge 208, the center line of the first waist-shaped slot 207 passes through the circle center of the connecting hole 302, and a fastener sequentially passes through the connecting hole 302, the first waist-shaped slot 207 and the second slot 501 to fixedly connect the cutter head 3, the cutter 2 and the pressing plate 5, wherein in the embodiment, the fastener is a screw 4; the length direction of the first waist-shaped slot 207 is parallel to the length extending direction of the second slope 203 and the fourth slope 206. The depth of the positioning chute 303 is greater than the height of the positioning boss 502, and the difference between the depth of the positioning chute 303 and the height of the positioning boss 502 is greater than the thickness of the cutter 2, so that the cutter head 3 and the pressing plate 5 can clamp the cutter 2 tightly. Meanwhile, the overall size of the positioning chute 303 may be designed to be larger than the overall size of the positioning boss 502, and the length and the width of the positioning chute 303 are both larger than the positioning boss 502 as shown in fig. 3, so that the positioning boss 502 can slide in the positioning chute 303.

When in installation, the screws 4 are pre-connected through the two second slotted holes 501 on the pressing plate 5 and the two connecting holes 302 on the cutter head 3, namely, the cutter head 3 and the pressing plate 5 are not fixed tightly, two positioning bosses 502 at the lower end of the pressing plate 5 are respectively inserted into the positioning chutes 303 on the cutter head 3, and because of the dead weight, the pressure strip 5 will naturally fall, the positioning boss 502 will slide in the positioning chute 303, at this moment, the first waist-shaped slot 207 on the cutter 2 is clamped into the screw 4 and inserted between the pressure strip 5 and the cutter head 3 along the length direction of the first waist-shaped slot 207, the oblique insertion of the cutter 2 has the advantages of more convenient positioning, after the cutter 2 is inserted, the clamping end 201 at the upper end of the cutter 2 is clamped by the positioning rod 301 along the direction of the second slope surface 203, because the first slope surface 202 and the second slope surface 203 are inclined upwards, the cutter 2 is positioned more stably and cannot deviate in the front-back direction; in this embodiment, the second slot 501 is an oblong hole, and after the cutting knife 2 is clamped, the pressing plate 5 is lifted up, so that the two positioning bosses 502 below the pressing plate 5 support the third slope 204 and the fourth slope 206 at the lower end of the cutting knife 2, and the positioning rod 301 is ensured to clamp the clamping end 201 and then screw the screw 4 tightly.

As shown in fig. 5, which is a schematic view showing the installation of the cutter assemblies, the cutter 2 is a single-side edge, and the edge end faces the discharging template 1, it should be understood that the above-mentioned figure is only one of the cutter assemblies of the whole bulking machine, and in actual production, a plurality of cutter assemblies are installed on the cutter frame for rotary cutting according to production requirements. In the embodiment, the cutter is limited between the cutter disc and the pressing plate by arranging the fixing groove and the thrust part on the cutter and matching the positioning rod on the cutter disc and the positioning boss on the pressing plate, so that the cutter can be accurately positioned and can be effectively prevented from displacing in the working process; meanwhile, the cutter can be conveniently detached by arranging the first waist-shaped slotted hole on the cutter; the cutter has the advantages of convenient installation and replacement, accurate positioning, difficult displacement and the like.

Example two:

the difference between the embodiment and the first embodiment is that, in the embodiment, the second slot 501 on the pressing plate 5 is a circular hole, and after the setting is adopted, the installation sequence of the cutter 2 changes, and the specific installation mode is that the cutter 2 is installed at a proper position of the cutter disc 3 first, so that the clamping end 201 is clamped by the positioning rod 301, and then the cutter 2 is pressed tightly by the screw 4 penetrating through the circular second slot 501 on the pressing plate 5 and the connecting hole 302 on the cutter disc 3.
