Description

Technical Field

[0001] The invention relates to a cardboard slotting machine, in particular to a bidirectional cardboard slotting machine capable of slotting cardboard twice. Background Art

[0002] Generally, paper packaging containers such as paper boxes and cartons are made by folding paperboard with grooves along the grooves. A paperboard slotting machine is a device for slotting paperboard. At present, the general paperboard slotting machines on the market include a primary slotting mechanism and a secondary slotting mechanism. Both the primary slotting mechanism and the secondary slotting mechanism include slotting knives, slotting rollers and paper pressing belts. The primary slotting mechanism completes a transverse slotting, and the secondary slotting mechanism completes a secondary longitudinal slotting. However, the primary slotting mechanism and the secondary slotting mechanism of the existing paperboard slotting machine are two independent mechanisms, and because the two independent slotting mechanisms are located in different positions, the size of the whole machine is very large, and the other two independent slotting mechanisms require two servo motors, which is relatively expensive.

[0017] like Figure 1 and Figure 2 The same-side bidirectional cardboard slotting machine comprises a frame 1, a slotting mechanism 2 and a flipping and feeding mechanism 5. The slotting mechanism 2 is used to perform primary and secondary slotting on the cardboard, and the flipping and feeding mechanism 5 is used to flip the cardboard after the primary slotting and then send it for secondary slotting.

[0018] like Figure 3 and Figure 4As shown, the slotting mechanism 2 includes a slotting roller 20, and the slotting roller 20 has a primary slotting position 21 and a secondary slotting position 22 arranged on the left and right, the primary slotting position 21 is correspondingly provided with a primary slotting knife 23 and a primary paper pressing belt 25, and the secondary slotting position 22 is correspondingly provided with a secondary slotting knife 24 and a secondary paper pressing belt 26; the primary paper pressing belt 25 and the secondary paper pressing belt 26 are both pressed on the slotting roller 20, the primary paper pressing belt 25 cooperates with the slotting roller 20 to turn over and convey the cardboard, and at the same time, the primary slotting knife 23 performs a primary slot on the cardboard, and the secondary paper pressing belt 26 also cooperates with the slotting roller 20 to turn over and convey the cardboard, and at the same time, the secondary slotting knife 24 performs a secondary slot on the cardboard.

[0019] Since the primary slotting position 21 and the secondary slotting position 22 are distributed on the left and right, or since the original primary slotting mechanism and the secondary slotting mechanism are arranged on the left and right and share a slotting roller, the conveying path of the cardboard should also be adjusted accordingly, and the specific adjustments are as follows: the feeding end of the primary slotting position 21 and the feeding end of the secondary slotting position 22 are both located at the top and arranged side by side on the left and right, and the discharging end of the primary slotting position 21 and the discharging end of the secondary slotting position 22 are both located at the bottom; the discharging end of the primary slotting position 21 is conveyingly connected to one end of the turning feeding mechanism 4, and the other end of the turning feeding mechanism 4 is conveyingly connected to the feeding end of the flipping feeding mechanism 5, and the discharging end of the flipping feeding mechanism 5 is conveyingly connected to the deviation correcting conveying mechanism 6, and the conveying direction of the deviation correcting conveying mechanism 6 intersects with the discharging direction of the flipping feeding mechanism 5 (that is, one conveying direction is forward and the other is rightward), and the deviation correcting conveying mechanism 6 is conveyingly connected to the feeding end of the secondary slotting position 22.

[0020] like Figure 1-Figure 4 as well as Figure 7 As shown, the cardboard enters from the feed end of the primary slotting position 21, and the primary slotting knife 23 performs a transverse slotting on the cardboard. After slotting, the cardboard comes out from the discharge end of the primary slotting position 21, and then the cardboard comes to the turning feeding mechanism 4, the turning feeding mechanism 4 turns the cardboard by 90°, and then enters the flipping feeding mechanism 5, the flipping feeding mechanism 5 flips the cardboard from bottom to top by 180° and sends it to the top, and the cardboard enters the deviation correction conveying mechanism 6 (the deviation correction conveying mechanism 6 is the prior art), and after the deviation correction conveying mechanism 6 corrects the deviation, the cardboard enters the feed end of the secondary slotting position 22, and then the cardboard enters from the feed end of the secondary slotting position 22, and the secondary slotting knife 24 performs a secondary longitudinal slotting on the cardboard, and finally comes out from the discharge end of the secondary slotting position 22, thereby completing the bidirectional slotting of the cardboard. Since the primary slotting position 21 and the secondary slotting position 22 share a slotting roller 20, the volume of the whole machine is greatly reduced, the structure is more compact, and the equipment manufacturing cost is also lower.

[0021] As described above, the turning feeding mechanism 4 can turn the cardboard through a 90° angle. Figure 2 and 5As shown, the turning feeding mechanism 4 includes a turning belt 40 and two turning rollers 41 arranged perpendicularly, the diameter of the turning rollers 41 gradually increases from one end to the other, and the turning belt 40 is wound around the two turning rollers 41. Driven by a power source, the turning belt 40 realizes turning transmission on the two turning rollers 41, thereby making a 90° turn with the paperboard.

[0022] Of course, there is a certain distance between the turning feeding mechanism 4 and the discharge end of the primary slotting position 21. For this reason, the present invention provides a linear conveying mechanism 3 between the discharge end of the primary slotting position 21. The linear conveying mechanism 3 is a common conveyor belt conveying mechanism, whose feed end is connected to the discharge end of the primary slotting position 21 for conveying, and whose discharge end is connected to the turning feeding mechanism 4 for conveying. Of course, if the turning feeding mechanism 4 is made long enough, the linear conveying mechanism 3 may not be needed, and the feed end of the turning feeding mechanism 4 is directly connected to the discharge end of the primary slotting position 21 for conveying.

[0023] After turning the turning feeding mechanism 4, the cardboard enters the flipping feeding mechanism 5, which realizes the flipping of the cardboard. It can have multiple structures, such as forming an arc-shaped transmission channel through a plurality of guide rollers, such as Figure 2 and Figure 6 As shown, the present invention provides a flip feeding mechanism 5, which includes a flip roller 50, a lower flip belt 51 and an upper flip belt 52. The lower flip belt 51 and the upper flip belt 52 are both attached to the flip roller 50 through guide rollers, and a flip feed port and a flip discharge port are formed between the lower flip belt 51 and the upper flip belt 42. After the cardboard is sent over, it enters from the flip feed port. Under the rotation of the flip roller 50, the cardboard flips 180° from bottom to top, comes out from the flip discharge port, and enters the feed end of the secondary slotting position. It is worth mentioning here that in order to flip cardboards of different thicknesses, the upper flip belt of the present invention is an elastic rubber belt. Since the upper flip belt is elastic, it can convey cardboards of different thicknesses.

[0024] As described in the background technology, the primary slotting mechanism and the secondary slotting mechanism of the existing cardboard slotting machine are two independent mechanisms. This independent structure directly results in that the paper pressing belt of each slotting mechanism can only be located on one side of the slotting roller in the form of a triangle through the guide roller, and the slotting knife is also installed on the same side. Therefore, the paper pressing belt will interfere with the adjustment of the slotting knife, and it will be very inconvenient to adjust the slotting knife. However, since the present technical solution concentrates the primary slotting position 21 and the secondary slotting position 22 in one position (i.e., they are arranged side by side on the same side), the winding method of the primary paper pressing belt 25 and the secondary paper pressing belt 26 can be improved to avoid the slotting knife. The specific improvements are as follows: Figure 3As shown, a front upper guide roller 11 and a front lower guide roller 10 are provided on the frame 1 in front of the slotting roller 20, a rear upper guide roller 13 is provided on the frame 1 above the slotting roller 20 (the rear upper guide roller 13 is located above the slotting roller 20 relative to the axis of the slotting roller 20, the same below), an upper guide wheel 12 is provided on the frame 1 above the rear upper guide roller 13, a rear lower guide roller 14 is provided on the frame 1 below the slotting roller 20, and a lower guide wheel 15 is provided on the frame 1 below the rear lower guide roller 14. The primary paper pressing belt 25 and the secondary paper pressing belt 26 are both wound around the front lower guide roller 10, the front upper guide roller 11, the upper guide wheel 12, the rear upper guide roller 13, the slotting roller 20, the rear lower guide roller 14 and the lower guide wheel 15. Thanks to the concentration of the primary slotting position 21 and the secondary slotting position 22, the primary paper pressing belt 25 and the secondary paper pressing belt 26 can bypass the front part of the equipment, thereby freeing up space on the rear side of the slotting roller 20 for placing the slotting knife only. In this way, there will be no interference when adjusting the slotting knife, and the adjustment of the slotting knife is easier.
