[0019] To make the purpose, technical scheme and advantage of the embodiment of the present application more clear, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application, obviously, the described embodiment is a part of the embodiment of the present application, not all the embodiment of the present application. Based on the embodiment in the present application, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of protection of the present application. It should be noted that, in the case of no conflict, the embodiment in the present application and the feature in the embodiment can be combined with each other.

[0020] The cutter roll side door locking device of the utility model, as shown in Figs. 1-3 The locking seat 2 is provided with the clamping groove 21, and the locking block 4 is inserted into the clamping groove 21, so that the door plate 3 and the door frame 1 are fixed to each other.

[0021] In the embodiment, the door frame 1 and the door plate 3 are relatively fixed by the plug-in mode, the locking effect is achieved, and the opening and closing operation of the door plate 3 is facilitated. The one side edge of the door plate 3 is rotatably connected to the door frame 1 through a rotating shaft, and the locking device of the cutting machine knife roll side door is arranged near the other side edge. When the door plate 3 is rotated towards the door frame 1 and is buckled with the door frame 1, the locking block 4 is inserted into the locking seat 2, the door plate 3 is fixed with the door frame 1, the closing and locking operation of the cutting machine knife roll side door is completed. When the cutting machine knife roll side door needs to be opened, the locking block 4 is pulled out of the locking seat 2, and the door plate is reversely rotated, so that the opening operation of the cutting machine knife roll side door is completed.

[0022] In the embodiment, the cutting machine knife roll side door locking device further comprises a cylinder 5, the cylinder 5 drives the locking block 4 to move to be inserted into the clamping groove 21 or pulled out of the clamping groove 21, so that the automatic opening and closing operation of the cutting machine knife roll side door is realized. Specifically, the cylinder 5 is a self-locking cylinder, the locking block 4 is fixedly connected to a push rod 51 of the cylinder 5, and the push rod 51 drives the locking block 4 to be inserted into the clamping groove 21 or pulled out of the clamping groove 21. The self-locking cylinder has a self-locking function when the gas source fails in the working process, and the push rod 51 can be locked and kept at a set position.

[0023] In the embodiment, the cutting machine knife roll side door locking device further comprises a control switch for controlling the movement of the cylinder 5, and the movement of the cylinder 5 is controlled through the switch, that is, the locking and unlocking of the cutting machine knife roll side door is controlled.

[0024] As another embodiment of the utility model, the locking block 4 can also be driven by a linear motor or the like.

[0025] In the embodiment, the support 6 is provided with a guide groove 61, and the locking block 4 is arranged in the guide groove 61. The guide groove 61 can support and guide the locking block 4, ensure that the locking block 4 is aligned with the clamping groove 21 and is smoothly inserted into the clamping groove 21, and can avoid that the gravity of the locking block 4 forms a radial pressure on the push rod 51 and affects the operation of the cylinder 5.

[0026] In the embodiment, in order to increase the locking force between the locking block 4 and the locking seat 2, the locking block 4 is provided with at least one inclined surface 41, so that the locking block 4 is trapezoidal, the shape of the clamping groove 21 is matched with the locking block 4, the pressure between the locking block 4 and the locking seat 2 is continuously increased with the increasing depth of the locking block 4 inserted into the clamping groove 21, and the locking block 4 and the locking seat 2 are tightly inserted together.

[0027] In the embodiment, the locking seat 2 is in the shape of a cylinder, is arranged perpendicularly to the door frame 1, and is fixedly connected to the door frame 1 by a screw at one end and is provided with a clamping groove 21 along the radial direction of the locking seat 2 at the other end.

[0028] In the embodiment, the door frame 1 comprises a mounting surface on which the air cylinder 5 and the locking block 4 are mounted, and a buckling surface opposite to the mounting surface; and a connecting hole (not shown in the figure) is arranged at the position corresponding to the locking seat 2 along the cross-sectional direction of the door frame 1 and penetrates through the door frame 1, so that when the door plate 3 is buckled to the door frame 1, the one end of the clamping groove 21 of the locking seat 2 can be passed out of the connecting hole and is opposite to the locking block 4 on the side of the mounting surface of the door frame 1. The size of the connecting hole is slightly larger than the cross-sectional size of the locking seat 2, so as to ensure that the locking seat 2 is smoothly inserted into the connecting hole.
