A transverse cutting apparatus according to an embodiment of the present invention is described below with reference to fig. 1 to 5.

According to the utility model discloses transverse cutting device, as shown in fig. 1 to 5, include:

a frame 100;

the two cutter shafts 200 are horizontally arranged on the rack 100, the two cutter shafts 200 are parallel to each other and are distributed up and down, one side of each cutter shaft 200 is provided with a detachable cutter 201 along the axial direction, and one side of each cutter shaft 200, which is far away from the corresponding cutter 201, is provided with a plurality of detachable counterweight units 202;

and the driving mechanism 300 is arranged on the frame 100 and is in transmission connection with the cutter shaft 200 so as to control the cutter shaft 200 to rotate.

In this embodiment, when the paperboard needs to be transversely cut, the paperboard is conveyed to a position between the two cutter shafts 200 through the conveying mechanism 400 or manually, then the two cutter shafts 200 are controlled to rotate through the driving mechanism 300, and the two cutters 201 can be controlled to be matched to transversely cut the paperboard in the rotating process of the two cutter shafts 200. According to the utility model discloses transverse cutting device because one side that arbor 200 deviates from cutter 201 is provided with a plurality of counter weight units 202, the total weight of a plurality of counter weight units 202 can with cutter 201's weight looks adaptation, and then make arbor 200 atress comparatively even to make arbor 200 less at the vibration that the pivoted in-process produced, the stationarity is better during the operation. Secondly, cutter 201 can be dismantled, and then when needing to clean, maintain or change cutter 201, it is more convenient to operate. In addition, after the cutter 201 is replaced by different models or sizes, the weight of the cutter 201 may be changed, and the counterweight units 202 can be disassembled and assembled, so that the number of the counterweight units 202 can be increased or decreased according to the weight of the cutter 201, the total weight of the counterweight units 202 is matched with the weight of the cutter 201, and therefore after the cutter 201 is replaced, vibration generated by the cutter shaft 200 in the rotating process is small, and the stability during operation is good.

It should be noted that, in order to enable the cutters 201 on the two cutter shafts 200 to cooperate to transversely cut the paper sheets, the installation positions of the cutters 201 on the two cutter shafts 200 need to be corresponding, specifically, when the cutter 201 on the upper cutter shaft 200 is located at the bottom end of the corresponding cutter shaft 200, the cutter 201 on the lower cutter shaft 200 is located at the top end of the corresponding cutter shaft 200, so as to cooperate to cut the paper sheets; when the cutter 201 on the upper cutter shaft 200 is located at the top end of the corresponding cutter shaft 200, the cutter 201 on the lower cutter shaft 200 is located at the bottom end of the corresponding cutter shaft 200, so that the lower cutter shaft 200 is in a non-working state, and the paperboard is transversely cut once when the cutter shaft 200 rotates for one circle. The frame 100 may be provided with a conveying mechanism 400, and the end of the conveying mechanism 400 is close to the gap between the two knife shafts 200, so as to convey the paperboard to the gap between the two knife shafts 200 for transverse cutting. When different types or sizes of paperboards are transversely cut, the cutters 201 of different types or sizes may need to be replaced, so that the counterweight units 202 need to be added or reduced. The total weight of the plurality of weight units 202 is adapted to the weight of the cutter 201, and the weights are not necessarily completely equal, and the weight difference between the two weights is only required to be within a proper range. The driving mechanism 300 may include two driving motors, output shafts of the two driving motors may be directly coaxially connected with the corresponding cutter shafts 200, and output shafts of the two driving motors may also be indirectly in transmission connection with the corresponding cutter shafts 200 through a reducer, so that the two driving motors respectively drive the corresponding cutter shafts 200 to rotate. The driving mechanism 300 may also include a driving motor, the driving motor is coaxially connected with one of the knife shafts 200 or indirectly connected through a reducer in a transmission manner, the end portions of the two knife shafts 200 may be respectively provided with a gear, the two gears are engaged, and then one knife shaft 200 may drive the other knife shaft 200 to rotate when rotating, thereby realizing that the two knife shafts 200 rotate together.

In some embodiments of the present invention, as shown in fig. 2, the counterweight unit 202 has a long bar-shaped structure and extends along the axial direction of the arbor 200. Because cutter 201 is rectangular shape structure and along the axial extension of arbor 200, in this embodiment, set up counter weight unit 202 into rectangular shape structure equally and along the axial extension of arbor 200, can more correspond with cutter 201, and then make arbor 200 atress comparatively even to make arbor 200 vibration that the pivoted in-process produced less, the stationarity is better during the operation.

According to some embodiments of the present invention, as shown in fig. 2, both ends of the weight unit 202 are flush with both ends of the arbor 200. The both ends of cutter 201 generally extend to the both ends of arbor 200, and in this embodiment, set the both ends of counter weight unit 202 to the both ends parallel and level with arbor 200, can more correspond with cutter 201, and then make arbor 200 atress comparatively even to make arbor 200 vibration that the pivoted in-process produced less, the stationarity is better when moving. The two ends of the arbor 200 refer to the two ends of the arbor 200 body, and do not include the installation axis portion of the arbor 200.

When the counterweight unit 202 needs to be added or reduced, the locking nut 204 is screwed off, then the counterweight unit 202 needing to be added is sleeved on the mounting screw rod 203 or the counterweight unit 202 needing to be reduced is taken down from the mounting screw rod 203, and then the locking nut 204 is screwed again. It should be noted that the counterweight unit 202 may also be clamped on the arbor 200, or be connected and installed on the arbor 200 by clamping and bolt connection.

According to some embodiments of the present invention, as shown in fig. 4, the mounting screw 203 is threadedly connected with a retaining nut 205 at a side of the locking nut 204 departing from the counterweight unit 202. In a long-time working process, the locking nut 204 may be loosened, so that not only the locking effect of the weight unit 202 may be reduced, but also when the locking nut 204 is completely loosened, a situation in which the weight unit 202 falls down to cause a safety accident may occur. In this embodiment, the mounting screw 203 is further connected with a retaining nut 205 through a thread on the side of the lock nut 204 departing from the counterweight unit 202, the retaining nut 205 can prevent the lock nut 204 from loosening, and the retaining nut 205 is tightly attached to the lock nut 204 and can also prevent the self from loosening. It should be noted that, in order to better lock the weight unit 202, a spring washer or a flat washer may be sleeved on the mounting screw 203 between the lock nut 204 and the outermost weight unit 202.
