The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

Referring to fig. 1 to 4, an embodiment of a cutter head suspension device of a cutting bed of the invention is shown.

Referring to fig. 1, 2 and 3, the cutter head suspension device of the cutting bed of the present embodiment includes a driving member 1, a guide post 2, a connecting member 3, a limiting member 4 and a clamping assembly. The driving member 1 is used for driving the cutter head 200 to move up and down relative to the cutting bed frame 100, so as to realize that the cutter head 200 moves up and down relative to the fabric 300 to be cut, which is placed on the worktable of the cutting bed. The guide post 2 is arranged on the cutter head 200, the connecting piece 3 is arranged on the guide post 2 in a liftable way, the limiting piece 4 is arranged on the connecting piece 3, and the limiting piece 4 is opposite to the cutter head 200 above the cutter head 200 at intervals. The clamping assembly acts on the connecting member 3 and fixes or elevates the connecting member 3 with respect to the cutting bed frame 100.

When the clamping assembly enables the connecting piece 3 to be capable of lifting relative to the cutting machine frame 100, in the process that the driving piece 1 drives the cutter head 200 to lift relative to the cutting machine frame 100, the connecting piece 3 and the limiting piece 4 can synchronously lift with the cutter head 200 under the driving of the cutter head 200 along with the guide column 2, so that the cutter head 200 cannot obstruct the lifting of the cutter head 200, and at the moment, the cutter head 200 can realize the normal cutter head lifting stroke required by the normal cutting operation of the cutting machine under the driving of the driving piece 1.

When the clamping component fixes the connecting piece 3 relative to the cutting bed frame 100, in the process that the driving piece 1 drives the cutter head 200 to ascend and descend relative to the cutting bed frame 100, the connecting piece 3 and the limiting piece 4 are fixed relative to the cutting bed frame 100 under the action of the clamping component, the guide column 2 ascends and descends synchronously under the driving of the cutter head 200, and the cutter head 200 is ascended and descended relative to the connecting piece 3, and at the moment, the cutter head 200 can be ascended to a certain height under the driving of the driving piece 1. The limiting piece 4 limits the maximum height of the cutter head 200 which can be lifted when the connecting piece 3 is fixed relative to the cutting machine frame 100, when the cutter head 200 is lifted to be in contact with the limiting piece 4, the cutter head 200 is blocked by the limiting piece 4 and cannot be lifted continuously, namely, the maximum height of the cutter head 200 which can be lifted when the connecting piece 3 is fixed relative to the cutting machine frame 100 is reached, and the initial spacing distance between the limiting piece 4 and the cutter head 200 determines the maximum height. Preferably, the maximum height of the cutter head 200 that can be raised when the attachment 3 is fixed with respect to the cutting bed frame 100 may be set to 2mm to 7 mm.

Therefore, by adopting the cutter head suspension device of the cutting bed of the embodiment, the connecting piece 3 can be lifted relative to the cutting bed frame 100 by the clamping component, and the driving piece 1 drives the cutter head 200 to ascend relative to the cutting bed frame 100, so that the fabric 300 to be cut can be placed on the cutting bed worktable and below the cutter head 200, and after the fabric 300 is placed, the driving piece 1 drives the cutter head 200 to descend relative to the cutting bed frame 100 to be contacted with and pressed against the fabric 300 (as shown in fig. 2). If the fabric 300 to be cut can slide along the cutter disc 200 under the pressure of the cutter disc 200 and cannot be kept fixed, the connecting piece 3 can be fixed relative to the cutting machine frame 100 through the clamping assembly, then the driving piece 1 drives the cutter disc 200 to ascend relative to the cutting machine frame 100, so that the cutter disc 200 ascends and is separated from the fabric 300 (as shown in fig. 4), until the cutter disc 200 ascends to be in contact with the limiting piece 4, the cutter disc 200 stops ascending, the driving piece 1 keeps a state of driving the cutter disc 200 to ascend, and then the fabric 300 is cut, at the moment, the cutter disc 200 is in a suspension state and has a spacing distance with the fabric 300 so as not to apply pressure to the fabric 300, therefore, the situation that the fabric 300 cannot be fixed due to sliding along the cutter disc 200 under the pressure of the cutter disc 200 is avoided, the smooth cutting process can be ensured, and the cutting quality is ensured. If the fabric 300 to be cut can be kept fixed under the pressure of the cutter 200, the fabric 300 can be normally cut without lifting the cutter 200 in a state that the cutter 200 is pressed against the fabric 300.

The connecting piece 3 can be pressed on the boss 21 of the guide post 2 through the elastic jacking action of the elastic piece 5, so that the positioning of the initial position of the connecting piece 3 on the guide post 2 is realized, when the elastic piece 5 is stressed to generate compression deformation or elastic recovery and extension, the lifting of the connecting piece 3 relative to the guide post 2 can be realized, and the lifting range of the connecting piece 3 relative to the guide post 2 is limited between the boss 21 and the cutter head 200. In this embodiment, preferably, the boss 21 is an annular boss extending circumferentially along the outer peripheral surface of the upper end of the guide post 2, and the connecting member 3 is sleeved on the guide post 2 in a liftable manner and is located between the boss 21 and the cutter head 200. The elastic piece 5 is also sleeved on the guide post 2, and the elastic piece 5 can adopt a compression spring.

Further, a first buffer pad 6 may be disposed between the connecting member 3 and the boss 21 of the guide post 2, and the first buffer pad 6 may be sleeved on the guide post 2. The first cushion pad 6 can buffer the contact between the boss 21 and the connecting piece 3 in the relative lifting process of the guide post 2 and the connecting piece 3, and the collision impact force is reduced. Preferably, the first cushion pad 6 may be a rubber pad.

Further, a guide bush 7 can be arranged between the connecting piece 3 and the guide post 2, the guide bush 7 can be fixed in the connecting piece 3, and the guide post 2 can be arranged in the guide bush 7 in a penetrating mode in a liftable mode.

Preferably, the second cushion pad 8 may employ a rubber pad.

Further, in this embodiment, the limiting member 4 is disposed on the connecting member 3 in a liftable manner, that is, the height position of the limiting member 4 relative to the connecting member 3 is adjustable, so that the adjustment of the distance between the limiting member 4 and the cutter head 200 can be realized, that is, the adjustment of the maximum height that the cutter head 200 can be lifted when the connecting member 3 is fixed relative to the cutting bed frame 100 is realized, which is beneficial to meeting the cutting requirements of the fabrics 300 with different heights.
