Description

Technical Field

[0001] The utility model relates to a screwdriver, in particular to a cutting device used for cardboard lamination. Background Art

[0002] After the rolled cardboard or corrugated paper is coated, it needs to be cut into small pieces. The existing cutting method usually uses a cutter to cut it, but the plastic film at the cut may be stretched during the cutting process; if the corrugated paper is cut back and forth using a cutting wheel, the cutting may not be complete, and there may be burrs, etc. Especially when the coated plastic film is thick, the disadvantages are particularly obvious. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a cutting device for cardboard lamination, which can completely cut off the cardboard behind the peritoneum.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cutting device for cardboard lamination, including two conveyor belts, a cutting carrier plate is provided between the two conveyor belts, the surface of the cutting carrier plate is flush with the conveyor belts, a cutter is provided above the cutting carrier plate, and also includes a cutting wheel sliding left and right on the cutting carrier plate, and the movement trajectory of the cutting wheel is in the same straight line as the cutting line of the cutter.

[0005] Preferably, the cutting wheel is connected to the slider via a first connecting rod, and the slider drives the cutting wheel to move left and right on the cutting bearing plate.

[0006] Preferably, the slider is driven to move by a screw rod, and the length of the screw rod extends to both sides of the conveyor belt, so that the cutting wheel can avoid the cutter when the slider slides to the end of the screw rod.

[0007] Preferably, the cutter is connected to the lifting rod through the second connecting rod, and the cylinder drives the lifting rod to move up and down. After the lifting rod 9 is raised, the height of the cutter 4 is higher than the height of the first connecting rod.

[0008] Preferably, pulleys are provided at both ends of the lifting rod, and slide rails matching with the pulleys are provided on both sides of the lifting rod.

[0009] Preferably, both sides of the cutting support plate are inclined downward.

[0010] The utility model provides a cutting device for cardboard lamination. When cutting the lamination cardboard, a cutting wheel is first used to cut the plastic film of the cardboard and form a cut mark on the cardboard; then a cutter is used to cut the same part of the cardboard, thereby the lamination cardboard can be completely cut without burrs and stress stretching of the plastic film.

[0018] like Figure 1-2 As shown, a cutting device for cardboard lamination includes two conveyor belts 1, a cutting carrier plate 3 is provided between the two conveyor belts 1, the surface of the cutting carrier plate 3 is flush with the conveyor belt 1, a cutter 4 is provided above the cutting carrier plate 3, and also includes a cutting wheel 5 sliding left and right on the cutting carrier plate 3, and the movement trajectory of the cutting wheel 5 is in the same straight line as the cutting line of the cutter 4.

[0019] Preferably, the cutting wheel 5 is connected to the slider 6 via the first connecting rod 2 , and the slider 6 drives the cutting wheel 5 to move left and right on the cutting bearing plate 3 .

[0020] Preferably, the slider 6 is driven to move by a screw rod 7. The length of the screw rod 7 extends to both sides of the conveyor belt 1, so that the cutting wheel 5 can avoid the cutter 4 when the slider 6 slides to the end of the screw rod 7. When the cutter is used for cutting, the cutting wheel is slid to the end to avoid the cutter.

[0021] Preferably, the cutter 4 is connected to the lifting rod 9 through the second connecting rod 8, and the cylinder drives the lifting rod 9 to move up and down. After the lifting rod 9 is raised, the height of the cutter 4 is higher than the height of the first connecting rod 2. When the cutting wheel is used for cutting, the cutter is raised to avoid the cutting wheel.

[0022] Preferably, Figure 3 As shown, pulleys 10 are provided at both ends of the lifting rod 9 , and slide rails 11 matching with the pulleys 10 are provided on both sides of the lifting rod 9 .

[0023] Preferably, Figure 4As shown, the two sides of the cutting carrier board 3 are tilted downwards to prevent the cutting carrier board 3 from obstructing the paperboard.

[0024] When using, Figure 5 As shown, first raise the cutter, then use the cutting wheel 5 to cut the laminated cardboard to cut the plastic film; then Figure 6 As shown, the cutting wheel 5 is slid to the end, and the cutter is used to cut downward to completely cut the cardboard.

[0025] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
