Description
Technical Field
The invention relates to transverse cutting equipment, in particular to transverse cutting equipment of a non-woven fabric folding machine.
Background
The transverse cutting equipment of the non-woven fabric folding machine in the related art has three forms as follows:
the basic structure of the first form is shown in fig. 7: driven by the gear 10a, the two round rollers 20a and 30a roll in pairs, wherein the lower roller 30a is a quenched smooth hard surface roller, and the upper roller 20a is a cutter roller with single edge. The cutter has the characteristics of simple structure, simple manufacture, convenient use and suitability for occasions with low requirements. However, when a high requirement is placed on the cutting edge, the rolling cutter with the structure cannot meet the requirement, and the rolling cutter can generate the defect of residual fiber;
the basic structure of the second form is shown in fig. 8: the two knife rolls 20b and 30b roll by the gear drive, wherein the two knife rolls 20b and 30b are respectively provided with spiral blades 21b and 31b, and the upper spiral blade 21b and the lower spiral blade 31b are matched. The cutter has the characteristics of complex structure, complex manufacture and convenient use, and can meet the high requirements in actual production. Because the result of the cutter is complex, the manufacturing precision is particularly high, the manufacturing and maintenance cost is high, and the cutting effect is poor once the manufacturing or maintenance precision cannot meet the requirement;
the basic structure of the third form is as shown in fig. 9: the upper and lower blades 20c and 30c are bisected. The cutter has the characteristics of simple structure, simple manufacture and good cutting effect, but the non-woven fabric must be static when the cutter is used for cutting, which not only affects the production efficiency, but also has adverse effect on the folding effect of the non-woven fabric.

In some embodiments, the second crosscutter assembly 30 is positioned directly below the first crosscutter assembly 20 to cut horizontally moving cut material. It will be appreciated that as the direction of movement of the material being cut changes (e.g., from horizontal movement to vertical movement), the position of the second and first cutter assemblies 30, 20 may also be adjusted accordingly (e.g., in a horizontally opposed arrangement). It will be appreciated that the crosscutting device 1 is not limited to use in a non-woven fabric folding machine.
As further shown in fig. 1, the frame 10 may be in a box shape in some embodiments, and may include a flat plate-shaped base 11, a first side plate 12 erected on the left side of the base 11, a second side plate 13 erected on the right side of the base 11, and a link 14 connected to the tops of the first side plate 12 and the second side plate 13.

The second transverse cutter assembly 30 is disposed opposite to the first transverse cutter assembly 20, and may include a second eccentric roller shaft 31 rotatably mounted on the first side plate 12 and the second side plate 13 of the frame 10, a second mounting seat 32 rotatably sleeved on the second eccentric roller shaft 31, and a second transverse cutter 33 mounted on the second mounting seat 32.
The rotation directions of the first eccentric roll shaft 21 and the second eccentric roll shaft 32 are opposite, and the eccentric points of the first eccentric roll shaft 21 and the second eccentric roll shaft 32 are synchronous closest and are synchronous farthest, so that when the first eccentric roll shaft 21 and the second eccentric roll shaft 31 synchronously rotate, the second mounting seat 32 and the first mounting seat 22 synchronously move in opposite directions or in opposite directions, and the second mounting seat 32 and the first mounting seat 22 also integrally move back and forth along with the first eccentric roll shaft 21 and the second eccentric roll shaft 31. In this way, by controlling the first eccentric roller shaft 21 and the second eccentric roller shaft 31, the speed of the second mounting seat 32 and the first mounting seat 22 moving forward can be controlled, so that the speed of conveying the cut materials such as non-woven fabrics can be synchronized, and the cut materials do not need to be stopped when cut.
The second cross cutter 33 is disposed opposite to the first cross cutter 23 to generate a cutting force when approaching each other. The guide mechanism 40 is disposed between the second mount 32 and the first mount 22 to ensure that the second mount 32 and the first mount 22 can only move toward or away from each other.
As shown in fig. 5, the pair of guide mechanisms 40 are disposed on two sides of the first mount 22 and the second mount 32, respectively, and each guide mechanism 40 may include a guide bearing 41 mounted on the first mount 22 and a guide rod 42 mounted on the second mount 32 in some embodiments, where the guide rod 42 is inserted into the guide bearing 41, and limits the first mount 22 and the second mount 32 to a direction moving toward or away from each other, so that the first mount 22 and the second mount 32 can only move toward or away from each other, thereby ensuring the cutting effect. The guide mechanism 40 may further include a guide bar mount 43 mounted on the second mount 32, the guide bar 42 being mounted in the guide bar mount 43.
In some embodiments, the transverse cutting apparatus 1 further includes a cutter pressing mechanism 50, where the cutter pressing mechanism 50 is mounted on the second mounting seat 32 and elastically presses against the first transverse cutter 23, so as to eliminate some dimensional errors when the first transverse cutter 23 is matched with the second transverse cutter 33, so as to ensure close fit between the first transverse cutter 23 and the second transverse cutter 33, thereby improving the cutting effect. Referring to fig. 6 together, the cutter pressing mechanism 50 may include a cutter bearing housing 51 rotatably coupled to the second mounting base 32 at a central portion thereof, a cutter bearing 52 mounted to one end of the cutter bearing housing 51, and an elastic member 53 mounted between the other end of the cutter bearing housing 51 and the second mounting base 32.
In some embodiments, the crosscutting device 1 further comprises a gapless gear set 60, the gapless gear set 60 comprising a first gear 61 mounted on the first eccentric roller shaft 21 and a second gear 62 mounted on the second eccentric roller shaft 31, the first gear 61 being in mesh with the second gear 62. Particularly noted during assembly are: the eccentric points of the two eccentric roll shafts are required to be closest to each other or furthest from each other. In order to ensure that the requirements are met, when the gapless gear set 60 is connected with the two eccentric roll shafts, one of the two eccentric roll shafts is connected by a key, and the other one of the two eccentric roll shafts is connected by a tension sleeve.
