Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a protective slitting machine blade fixing frame. Background Technique

[0002] A slitting machine is a device that slits strip-shaped materials into long strips. The slitting machine can be used for the slitting operations of paper products, plastic products and metal products. Different-width long strips are cut through the knives distributed on the slitting machine. In order to increase the safety during use, it is usually necessary to block the knives from the staff.

[0003] Most of the current conventional slitting machine blade fixing frames are composed of three-hole four-corner blades, fixing frames, screws and rivets, and do not include protective components. After the three-hole four-corner blades are fixed by screws, two sharp corners will be exposed, resulting in the operator's hands being easily scratched by the exposed knife sharp corners when adjusting the slitting specifications, increasing the danger during use, and not protecting the knife body and the operator.

[0004] To sum up, there is an urgent need for a protective slitting machine blade fixing frame with high safety to solve the above problems. Content of the Utility Model

[0021] The following will detail the preferred technical solutions of the present utility model in conjunction with the accompanying drawings.

[0022] Embodiment: A protective slitting machine blade fixing frame, as Figures 1 - 5 shown, includes an aluminum tool holder 1, a tungsten carbide blade 2, a fixed block 3, a first screw 4, a second screw 5, a protective plate 7, a connecting block 8, and a pushing plate 9. A longitudinal tightening groove is opened in the upper part of the aluminum tool holder 1, a fixing hole is opened at a position above the middle of the aluminum tool holder 1, the longitudinal tightening groove and the fixing hole on the aluminum tool holder 1 are communicated, a square groove occupying half of its own width is opened in the lower part of the front side of the aluminum tool holder 1, a tungsten carbide blade 2 is detachably arranged in the square groove in the lower part of the front side of the aluminum tool holder 1, the tungsten carbide blade 2 is rectangular, a fixed block 3 is detachably arranged on the other side of the tungsten carbide blade 2, inclined surfaces are opened at the lower right corners of the aluminum tool holder 1 and the fixed block 3, the combined width of the tungsten carbide blade 2 and the fixed block 3 is equal to the width of the square groove on the aluminum tool holder 1, three round holes are opened on both the fixed block 3 and the tungsten carbide blade 2, the upper part of the aluminum tool holder 1 is horizontally threadedly connected with a first screw 4, three second screws 5 are threadedly connected to the aluminum tool holder 1, the second screws 5 pass through the round holes on the fixed block 3 and the tungsten carbide blade 2, connecting blocks 8 are symmetrically connected to the front and rear of the lower part of the aluminum tool holder 1, a protective plate 7 is slidably connected between the two connecting blocks 8, the protective plate 7 is U-shaped, the width of the fixed block 3 is equal to the inner diameter width of the protective plate 7, pushing plates 9 are symmetrically connected to the upper and lower parts of the right side of the protective plate 7. By passing the second screws 5 through the round holes on the fixed block 3 and the tungsten carbide blade 2 and rotating the second screws 5 to be threadedly connected with the aluminum tool holder 1, the aluminum tool holder 1 is displaced to the cutter through the fixing hole, and the aluminum tool holder 1 is fixed on the cutter through the first screw 4, thereby realizing the installation of the aluminum tool holder 1, the tungsten carbide blade 2, and the fixed block 3. By moving the protective plate 7, the aluminum tool holder 1, the fixed block 3, and the protective plate 7 wrap the tungsten carbide blade 2 to block the staff and the tungsten carbide blade 2, playing a protective role.

[0023] As Figure 4 shown, it further includes an anti-slip ring 6, the inner ring of the fixing hole on the aluminum tool holder 1 is connected with the anti-slip ring 6, and the anti-slip ring 6 can increase the friction with the aluminum tool holder 1 to prevent it from shifting.

[0024] As Figure 6As shown in the figure, it further includes a fixed rod 10, a spring 11 and a detent 12. The front and rear of the lower part of the aluminum tool holder 1 are symmetrically connected with the fixed rod 10. The detent 12 is slidably connected to the fixed rod 10. Clamping holes are symmetrically opened up and down on both the front and rear sides of the protective plate 7. The detent 12 is clamped with the clamping holes in the lower part of the protective plate 7. A spring 11 is connected between the fixed rod 10 and the detent 12. By the cooperation of the detent 12 and the clamping holes on the protective plate 7, the protective plate 7 can be limited to prevent the protective plate 7 from shifting during the cutting operation of the tungsten carbide blade 2, which may affect the operation.

[0025] When the device needs to be used, the tungsten carbide blade 2 and the fixing block 3 are placed on the aluminum tool holder 1 in sequence. The second screw 5 penetrates through the tungsten carbide blade 2 and the fixing block 3, and the second screw 5 is rotated to be threadedly connected with the aluminum tool holder 1 to fix the tungsten carbide blade 2 for installation. Through the fixing holes on the aluminum tool holder 1, it is shifted to the cutter of the slitting machine. The anti-slip ring 6 can increase the friction force with the aluminum tool holder 1 to prevent it from shifting. Then, a tool is used to install the first screw 4 onto the aluminum tool holder 1 to fix the aluminum tool holder 1 on the cutter. The push plate 9 is pushed upward, and the push plate 9 drives the protective plate 7 to shift. The detent 12 is disengaged from the clamping hole in the upper part of the protective plate 7, and the detent 12 moves toward each other under the extrusion of the protective plate 7, and the spring 11 deforms adaptively. When the detent 12 reaches the same height as the clamping hole in the lower part of the protective plate 7, the spring 11 returns to its original state, and the detent 12 is reset under the elastic force of the spring 11 and is clamped with the clamping hole in the lower part of the protective plate 7, which is convenient for the tungsten carbide blade 2 to perform the cutting operation. The detent 12 can limit the protective plate 7 to prevent the protective plate 7 from shifting during the cutting operation of the tungsten carbide blade 2, which may affect the cutting effect. After the cutting operation is completed, the staff operates in the reverse order according to the above content, moves the push plate 9 downward to make the protective plate 7 move downward, and the detent 12 is re-clamped with the clamping hole in the upper part of the protective plate 7. The aluminum tool holder 1, the fixing block 3 and the protective plate 7 cooperate to wrap the tungsten carbide blade 2, which can play a protective function for the staff. Then, the aluminum tool holder 1 is disassembled from the cutter of the slitting machine, and the tungsten carbide blade 2 and the fixing block 3 are disassembled from the aluminum tool holder 1.

[0026] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
