DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] A cutting device for a suitcase shell, comprising a machine platform 1, a rotating platform 2, a support block 3, a moving arm 6 and a rotating cutter 8;

[0029] The rotating table 2 is mounted on the machine table 1 and rotated by a rotating drive mechanism. The rotating table 2 is arranged horizontally. The support block 3 is mounted on the rotating table 2. The size of the support block 3 matches the size of the box shell to be cut, so that the box shell can be covered and fixed on the support block 3. The center of the support block 3 and the rotation center of the rotating table 2 are located on the same vertical line. The support block 3 can rotate with the rotation of the rotating table 2.

[0030] The movable arm 6 is mounted on the machine platform 1 through a movable driving mechanism and an elastic movable mechanism. The movable arm 6 is in a long strip shape. The movable driving mechanism is mounted on the machine platform 1. The elastic movable mechanism is mounted on the movable driving mechanism. The movable arm 6 is mounted on the elastic movable mechanism. The length direction of the movable arm 6 is toward the center of the support block 3. The moving directions of the movable arm 6 and the elastic movable mechanism are parallel to the length direction of the movable arm 6.

[0031] The rotary cutter 8 is rotatably mounted on one end of the mobile arm 6 facing the support block 3, the rotary cutter 8 is horizontally rotatably arranged and driven to rotate by the first motor 12, and the rotary cutter 8 is used to cut the box shell when rotating, the rotation center of the rotary cutter 8 is fixedly connected with a rotating shaft 9, the rotating shaft 9 is rotatably mounted on the mobile arm 6, a first synchronous wheel 10 is fixedly mounted on the rotating shaft 9, the first motor 12 is mounted on the mobile arm 6, a second synchronous wheel 11 is mounted on the output end of the first motor 12, and the first synchronous wheel 10 and the second synchronous wheel 11 are connected through a first synchronous belt 13;

[0032] A rotating abutment wheel 7 is installed at one end of the movable arm 6 facing the support block 3, and the central axis of the abutment wheel 7 is vertically arranged so that the abutment wheel 7 can abut against the surface of the box shell and rotate horizontally.

[0033] The box shell to be cut is covered on the support block 3 and fixed, and the mobile driving mechanism drives the elastic moving mechanism and the moving arm 6 to move toward the center direction of the support block 3, so that the abutment wheel 7 abuts against the box shell, thereby cutting the box shell by the rotating rotary cutter 8, and the rotary driving mechanism drives the support block 3 and the box shell to rotate. During the rotation, the abutment wheel 7 is always pressed against the box shell by the elastic moving mechanism. Since the distance between the abutment wheel 7 and the rotary cutter 8 is fixed, when the abutment wheel 7 abuts against the box shell and rotates, the distance between the rotary cutter 8 and the box shell is also fixed, so that stable cutting can be performed. The box shell rotates one circle with the support block 3, so that the box shell can be completely cut. Therefore, the size of the machine 1 can be reduced and the footprint of the device can be reduced through the utility model.

[0034] The preferred technical solution is that the elastic moving mechanism includes a first track 14, a moving block 15, a first abutting block, a second abutting block and a spring 16;

[0035] The first track 14 is installed on the mobile driving mechanism and is driven to move by the mobile driving mechanism. The length direction of the first track 14 is parallel to the length direction of the mobile arm 6. The lower end of the mobile arm 6 is fixed with a moving block 15 slidably installed on the first track 14. The cross section of the first track 14 is "T"-shaped. The moving block 15 is matched and installed on the first track 14. The shape of the first track 14 limits the mobile arm 6 to be stable on the first track 14, thereby preventing the part of the mobile arm 6 extending out of the first track 14 from being too heavy, causing the other end of the mobile arm 6 to tilt and detach from the first track 14;

[0036] A first abutment block is fixedly provided at one end of the first track 14 facing the support block 3 , and a second abutment block is fixedly provided at the lower end of the movable arm 6 . The second abutment block is located in the direction of the first abutment block toward the support block 3 , and the first abutment block and the second abutment block are connected via a spring 16 .

[0037] The first track 14 moves toward the support block 3 under the drive of the mobile driving mechanism, and the moving distance is greater than the distance between the abutment wheel 7 and the support block 3, so that the abutment wheel 7 can compress the spring 16 when it abuts against the box shell, and the abutment wheel 7 is always pressed against the box shell by the elastic force of the spring 16, and when the mobile driving mechanism is not driven, the position of the first track 14 remains fixed, so that when the box shell rotates, the moving arm 6 will be pushed to slide on the first track 14 through the moving block 15, thereby changing the distance between the first abutment block and the second abutment block, and the abutment wheel 7 is always against the box shell during the rotation of the box shell through the elasticity of the spring 16.

[0038] The preferred technical solution is that the mobile driving mechanism includes a second track 17, a mobile plate 18 and a pushing cylinder 19;

[0039] The second rail 17 is fixedly mounted on the machine platform 1, and the length direction of the second rail 17 is parallel to the length direction of the movable arm 6. The movable plate 18 is slidably mounted on the second rail 17, and the movable plate 18 is driven to slide by the push cylinder 19;

[0040] The elastic moving mechanism is installed on the moving plate 18 .

[0041] In a preferred technical solution, the rotary drive mechanism includes a rotating column 20, a transmission column 21 and a second motor 24;

[0042] The upper end of the machine platform 1 is provided with a rotation groove, the lower end of the rotation column 20 is installed in the rotation groove through a bearing for rotation, and the rotating table 2 is fixedly installed on the upper end of the rotation column 20;

[0043] A through hole is provided downwardly through the bottom center of the rotating groove, and the transmission column 21 is arranged in the through hole. The upper end of the transmission column 21 is fixedly connected to the lower end center of the rotating column 20, and the transmission column 21 is connected to the second motor 24 and driven to rotate by the second motor 24.

[0044] A third synchronous wheel 22 is installed at the lower end of the transmission column 21 , the second motor 24 is installed at the lower end of the machine 1 , a fourth synchronous wheel 23 is installed at the output end of the second motor 24 , and the third synchronous wheel 22 and the fourth synchronous wheel 23 are connected by a second synchronous belt 25 .

[0045] According to a preferred technical solution, the support block 3 can be detachably mounted on the rotating table 2, a raising plate 4 is fixedly provided at the lower end of the support block 3, the length and width of the raising plate 4 are greater than the length and width of the support block 3, and the raising plate 4 is mounted on the rotating table 2 by bolts.

[0046] The raising plate 4 firstly serves to connect the support block 3 and the rotating table 2. In addition, since the height of the rotating cutter 8 remains unchanged, by replacing the support block 3 with the raising plate 4 of different thicknesses, the cutting knife can perform cutting corresponding to different positions of the box shell.

[0047] According to a preferred technical solution, a circle of cutting grooves 5 is arranged around the side wall of the support block 3 .

[0048] Since the rotary cutter 8 needs to penetrate the box shell for cutting, the cutting groove 5 is arranged to correspond to the cutting position on the box shell, so that the rotary cutter 8 is located in the cutting groove 5 after penetrating the box shell, avoiding friction between the rotary cutter 8 and the surface of the support block 3, thereby avoiding grinding the cutting edge of the rotary cutter 8.
