[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0025] The utility model provides a horizontal slotting and creasing structure, including a slotting knife group 1 and / or a creasing knife group 2. The slotting knife group 1 includes a slotting knife 11, a slotting knife roller 12 and a first transmission roller 13. A slotting knife roller 12 is provided with a plurality of slotting knives 11. The plurality of slotting knives 11 are annularly distributed on the outer periphery of the slotting knife roller 12 and extend linearly along the axial direction of the slotting knife roller 12. The first transmission roller 13 is located below the slotting knife roller 12 to facilitate cardboard transmission.

[0026] The creasing knife group 2 includes a creasing knife 21, a creasing knife roller 22 and a second transmission roller 23. A plurality of creasing knives 21 are provided on a creasing knife roller 22. The plurality of creasing knives 21 are distributed in a ring around the outer periphery of the creasing knife roller 22 and extend in a straight line along the axial direction of the creasing knife roller 22. The second transmission roller 23 is located below the creasing knife roller 22 to facilitate cardboard transportation.

[0027] The slotting knife group 1 and the slotting knife group 1, the creasing knife group 2 and the creasing knife group 2, and the slotting knife group 1 and the creasing knife group 2 can form a combination, that is, on the same carton forming machine, the slotting knife group 1 and the slotting knife group 1 can form a slotting group; the creasing knife group 2 and the creasing knife group 2 can form a creasing group; and the slotting knife group 1 and the creasing knife group 2 can form a slotting and creasing group. The knife rollers are arranged parallel to each other in sequence, and the spacing between adjacent knife groups can be adjusted, specifically, by adjusting the position of the knife rollers relative to the carton forming machine. The specific structure involved is not repeated here.

[0028] In addition, the spacing between the plurality of slotting knives 11 on the same slotting knife roller 12 is adjustable; the spacing between the plurality of creasing knives 21 on the same creasing knife roller 22 is adjustable.

[0029] The specific structure of the slotting knife 11 is that it includes a first knife seat 111 and a slotting blade 112. The first knife seat 111 is extended axially along the slotting knife roller 12, and the slotting blade 112 is located in the center of the first knife seat 111. The bottom surface of the first knife seat 111 and the surface of the slotting knife roller 12 are tightly attached and adapted to each other, that is, the bottom surface of the first knife seat 111 is a circular arc surface, which fits tightly with the circular arc surface of the slotting knife roller 12. The first knife seat 111 is provided with a first fixing hole 113 on the front and rear sides of the slotting blade 112. A fastener is installed in the first fixing hole 113 to connect the first knife seat 111 to the surface of the slotting knife roller 12, so that the first knife seat 111 can adjust the installation position along the surface of the slotting knife roller 12, thereby realizing the adjustable position of the slotting knife 11, and then realizing the adjustable spacing between adjacent slotting knives 11 on the same slotting knife roller 12.

[0030] The specific structure of the indentation knife 21 is that it includes a second knife seat 211 and a indentation blade 212. The second knife seat 211 is extended axially along the indentation knife roller 22, and the indentation blade 212 is located in the center of the second knife seat 211. The bottom surface of the second knife seat 211 and the surface of the indentation knife roller 22 are tightly attached and adapted to each other, that is, the bottom surface of the second knife seat 211 is a circular arc surface, which is tightly fitted with the circular arc surface of the indentation knife roller 22. The second knife seat 211 is provided with a second fixing hole 213 on the front and rear sides of the indentation blade 212. A fastener is installed in the second fixing hole 213 to connect the second knife seat 211 to the surface of the indentation knife roller 22, so that the second knife seat 211 can adjust the installation position along the surface of the indentation knife roller 22, thereby realizing the adjustable position of the indentation knife 21, and then realizing the adjustable spacing between adjacent indentation knives 21 on the same indentation knife roller 22.

[0031] The above-mentioned slotting group may include two or more slotting knife groups 1, and the multiple slotting knife groups 1 are parallel to each other and arranged in parallel front and back. The first transmission rollers 13 are in the same horizontal position to facilitate the transmission of the cardboard. At this time, the rotation speed of each first transmission roller 13 is adjusted to be consistent, so that the cardboard is transmitted at a uniform speed. The spacing between each slotting knife group 1 is adjustable. The spacing between two adjacent slotting knife groups 1 is related to the spacing between the slotting knives 11 of the adjacent slotting knife groups 1, that is, the spacing between the corresponding two slots on the cardboard, so that the front and rear slot spacing on the cardboard can be adjusted.

[0032] Similarly, the creasing group may include two or more creasing knife groups 2, and the multiple creasing knife groups 2 are also arranged in the same manner as the slotting knife group 1, so that the front and back creasing distances on the cardboard can be adjusted.

[0033] The above-mentioned slotting and creasing group can include a slotting knife group 1 and a creasing knife group 2, or multiple slotting knife groups 1 and one creasing knife group 2, or one slotting knife group 1 and multiple creasing knife groups 2, each slotting knife group 1 and creasing knife group 2 is arranged parallel to each other, the slotting knife group 1 and the creasing knife group 2 can be arranged at intervals or in pairs, and can be freely combined and placed according to actual needs, and the distance between each slotting knife group 1 and the creasing knife group 2 can also be adjusted, that is, the distance between the slotting knife group 1 and the slotting knife group 1, the slotting knife group 1 and the creasing knife group 2, or the creasing knife group 2 and the creasing knife group 2 can be relatively adjusted, so that the slot and creasing spacing on the same cardboard can be adjusted.

[0034] In addition, in addition to adjusting the spacing between the knife rollers and the spacing between the knives on the same knife roller to achieve the spacing between the grooves or indentations on the cardboard, the rotation speed of the knife rollers and the transmission rollers can also be adjusted. That is, each of the slotting knife roller 12, the first transmission roller 13, the indenting knife roller 22 and the second transmission roller 23 is connected to a separate drive source 3, so that each knife roller and the transmission roller can rotate independently, thereby independently controlling its own rotation speed. When two adjacent knife rollers are at different rotation speeds, the spacing between the grooves or indentations formed on the cardboard front and back is also different. That is, when the knife rollers use different rotation speeds, the spacing between the grooves or indentations formed on the cardboard can be changed front and back, which is very flexible, and ultimately the spacing between the grooves or indentations on the cardboard can be flexibly adjusted. Of course, the change in the rotation speed of the transmission roller causes the cardboard conveying speed to change, which will also cause the spacing between adjacent grooves or indentations on the cardboard to change. That is, the purpose of adjusting the spacing between corresponding grooves or indentations on the cardboard can be achieved by simply adjusting the knife roller or the transmission roller, without having to adjust the position of the knife roller. This is very convenient and greatly improves work efficiency.

[0035] In addition, the slotting blade 112 is a U-shaped blade, whose blade path is U-shaped with one end open, and the distance between its two parallel straight blades is 2-15mm. The indenting blade 21 is a linear blade, and the width of the top end face of its blade is 0.5-4mm.

[0036] Finally, a few points should be explained: First, in the description of the present invention, it should be noted that, unless otherwise specified and limited, the terms "install", "fix" and "connect" should be understood in a broad sense, which can be mechanical connection or electrical connection, or internal communication between two components, or direct connection. "Up", "down", "left" and "right" are only used to indicate relative position relationships. When the absolute position of the described object changes, the relative position relationship may change. The present invention is not limited to the above-mentioned optimal implementation method. Anyone can derive various other forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, all technical solutions that are the same or similar to those of the present application fall within the scope of protection of the present invention.
