Compared with the existing cutting device 100 which drives the cutter through a plurality of driving parts to cut the product 200 to be processed, the cutting device 100 has simple structure and low price.

In order to make the technical solution of the present invention better understood, the technical solution of the embodiment of the present invention will be clearly and completely described below with reference to fig. 1 to 8.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 4 and 5, the eccentric connection assembly 44 includes an eccentric shaft 442 and a connection member 441 provided with an eccentric sleeve 443, one side of the connection member 441 is fixedly connected to the cutter assembly 43, one end of the eccentric shaft 442 is inserted into the eccentric sleeve 443, and the other end of the eccentric shaft is in transmission connection with the output shaft of the second driving member 42, so that the cutter assembly 43 can realize a multi-directional movement under the driving of the second driving member 42, thereby cutting the product 200 to be processed.

In this embodiment, the connecting member 441 has a mounting hole (not shown), and the eccentric sleeve 443 is mounted in the mounting hole. In addition, one end of the eccentric shaft 442 is provided with an insertion part (not shown) inserted into the eccentric sleeve 443, a gap exists between the outer side wall of the insertion part and the inner wall surface of the eccentric sleeve 443, and the other end of the eccentric shaft 442 is in transmission connection with the output shaft of the second driving member 42.

Understandably, when the second driving member 42 rotates, the output shaft of the second driving member 42 drives the eccentric shaft 442 to rotate, i.e. drives the insertion portion to rotate, and since there is a gap between the outer wall of the insertion portion and the inner wall of the eccentric shaft sleeve 443, along with the rotation of the insertion portion, the insertion portion abuts against the inner wall of the eccentric shaft sleeve 443 to drive the connecting member 441 to do periodic motion along multiple directions, i.e. to drive the cutter assembly 43 to do cutting motion, thereby cutting the product 200 to be processed.

It should be noted that the maximum distance that the connecting member 441 can move is determined by the gap between the eccentric sleeve 443 and the eccentric shaft 442, that is, the range of movement of the cutter assembly 43 is determined by the gap between the eccentric sleeve 443 and the eccentric shaft 442, and those skilled in the art can select the maximum distance according to actual situations.

Further, as a specific embodiment of the cutting device 100 provided by the present invention, as shown in fig. 4 and 5, a groove 411 is provided on one side of the substrate 41 away from the second driving member 42, and the connecting member 441 is accommodated in the groove 411 to reduce the space occupied by the connecting member 441, thereby reducing the overall size of the cutting device 100 and saving the space. In addition, in order to enable the connecting member 441 to move periodically along multiple directions, i.e. to drive the cutter assembly 43 to perform a cutting motion, a moving gap 412 exists between the side wall of the connecting member 441 and the wall of the groove 411.

In the process that the connecting element 441 periodically moves in the groove 411 in multiple directions, the moving gap 412 can prevent the connecting element 441 from interfering with the groove wall of the groove 411, which prevents the cutter assembly 43 from cutting the product 200 to be processed. It should be noted that the size of the movement gap 412 is determined by the range of movement of the cutter assembly 43, and can be selected by one skilled in the art based on the actual circumstances.

In this embodiment, the eccentric shaft 442 is geared to the output shaft of the second driver 42. Specifically, the output shaft of the second driving member 42 is provided with a first gear 421, the eccentric shaft 442 is provided with a second gear 4421, and the first gear 421 and the second gear 4421 are engaged with each other. It can be understood that when the second driving member 42 rotates, the output shaft of the second driving member 42 drives the first gear 421 to rotate, the first gear 421 drives the second gear 4421 to rotate, and the second gear 4421 drives the eccentric shaft 442 to rotate, so as to drive the connecting member 441 to perform a periodic motion along multiple directions, i.e. to drive the cutter assembly 43 to perform a cutting motion, thereby cutting the product 200 to be processed.

Of course, in other embodiments, the eccentric shaft 442 and the output shaft of the second driving member 42 may adopt other transmission structures, which the present invention is not limited to, and those skilled in the art can select them according to the actual situation.

Further, as a specific embodiment of the cutting device 100 provided by the present invention, as shown in fig. 3 and fig. 6, in order to enable the cutter assembly 43 to cut the product 200 to be processed from the inside, the cutter assembly 43 includes an inner knife 431, the inner knife 431 has a base portion 4311 and a cutting portion 4312, one side of the connecting piece 441 is fixedly connected to the base portion 4311, one side of the base portion 4311, which is away from the connecting piece 441, is concavely provided with a receiving groove 4313, and the cutting portion 4312 is convexly provided on a bottom wall of the receiving groove 4313.

As will be appreciated, when the product to be processed 200 is required to be cut, the first driving member 32 drives the cutting mechanism 40 to move integrally in a direction close to the product to be processed 200, and at this time, the inner knife 431 abuts against the end of the product to be processed 200. Specifically, the end of the product 200 to be processed abuts against the bottom wall of the accommodating groove 4313, the cutting portion 4312 is inserted into the inner cavity of the product 200 to be processed, and the cutting portion 4312 abuts against the inner wall of the product 200 to be processed, and then the output shaft of the second driving member 42 drives the connecting member 441 to move periodically in multiple directions to drive the inner knife 431 to perform cutting movement, so that the cutting portion 4312 cuts the product 200 to be processed from the inside.

Further, as a specific embodiment of the cutting device 100 provided by the present invention, as shown in fig. 6, the shape of the cutting portion 4312 is adapted to the shape of the cross section of the product 200 to be processed, so that the cutting portion 4312 abuts against the inner wall of the product 200 to be processed. Specifically, in the present embodiment, the product 200 to be processed is a rectangular metal tube, so the cutting portion 4312 is rectangular to ensure that the cutting portion 4312 can be inserted into the inner cavity of the rectangular metal tube and abut against the inner wall of the rectangular metal tube.

Of course, in other embodiments, the shape of the cutting portion 4312 may also be circular, trapezoidal, or other shapes, as long as it is ensured to be able to adapt to the product 200 to be processed, and the present invention does not limit this, and those skilled in the art can select this according to actual situations.

Further, as a specific implementation manner of the cutting device 100 provided by the utility model, as shown in fig. 3 and fig. 6, in order to prevent the cutting from remaining the waste material produced after waiting to process the product 200, the cutter still includes the material returning plate 432 that sets up in the holding tank 4313, has seted up the through-hole 4321 on the material returning plate 432, and the cutting portion 4312 passes the through-hole 4321 and protrudes in the material returning plate 432. It can be understood that, when the product 200 to be processed is cut, the first driving member 32 drives the cutting mechanism 40 to move integrally in a direction close to the product 200 to be processed, the end of the product 200 to be processed abuts against the top surface of the material discharge plate 432, the portion of the cutting portion 4312 protruding from the material discharge plate 432 is inserted into the inner cavity of the product 200 to be processed, and the cutting portion 4312 abuts against the inner wall of the product 200 to be processed, and then the second driving member 42 drives the inner knife 431 to perform a cutting motion, so that the cutting portion 4312 cuts the product 200 to be processed from the inside.

Therefore, on the one hand, since the stripper plate 432 is placed in the receiving groove 4313 of the base body 4311, the cut waste is not easily left in the receiving groove 4313, and on the other hand, when the waste needs to be cleaned, the stripper plate 432 is simply taken out from the receiving groove 4313, which is simple and convenient.

Further, as a specific embodiment of the cutting device 100 provided by the present invention, the cutter assembly 43 further includes a backing plate 433, the backing plate 433 is disposed between the base portion 4311 and the connecting member 441. Therefore, when the first driving element 32 drives the cutting mechanism 40 to move in the direction close to the product 200 to be processed, the cutting mechanism 40 moves for an excessively long distance, so that the base portion 4311 of the inner blade 431 and the connecting piece 441 are squeezed, and the inner blade 431 or the connecting piece 441 are prevented from being damaged.

Further, as the utility model provides a cutting device 100's a specific implementation mode, as shown in fig. 1, fig. 2 and fig. 7, between cutter unit 43 and fixture 20, cutting device 100 still includes limiting plate 50, limiting plate 50 and 41 fixed connection of base plate, and limiting plate 50 set up with treat the spacing hole 51 of processed product 200 looks adaptation, when cutting mechanism 40 to being close to when treating the removal of processed product 200 direction, treat that processed product 200 passes spacing hole 51, and push up with cutter unit 43 counterbalance, in order to avoid treating that processed product 200 takes place the problem that offset or rock when the cutting, further strengthen treating the fixed of processed product 200.

It can be understood that, when the first driving member 32 drives the cutting mechanism 40 to move in the direction close to the product 200 to be processed, the product 200 to be processed first passes through the limiting hole 51, and an external force is applied to the product 200 to be processed due to the cutting, so that the product 200 to be processed tends to move, at this time, the hole wall of the limiting hole 51 can block the product 200 to be processed from moving, i.e., the position of the product 200 to be processed is limited, thereby further enhancing the fixation of the product 200 to be processed, and avoiding the problem that the product 200 to be processed shifts or shakes during the cutting.

Further, as a specific embodiment of the cutting device 100 provided by the present invention, as shown in fig. 1, fig. 2 and fig. 8, the clamping mechanism 20 includes at least one clamping member 21, the clamping member 21 has a clamping groove 211, and the clamping groove 211 is used for fixing the product 200 to be processed.
