Detailed Description

The present application is described in further detail below with reference to figures 1-3.

Referring to fig. 1, a die-cutting machine, including base 1, install fuselage 2 on base 1, rotate and connect the material platform 3 that fuselage 2 was equipped with fixed plate one end, rotate and connect on fuselage 2 and with material platform 3 pivot 4 that the axis is parallel, fixed cover is established at 4 both ends of pivot and two circular carousel 5 that are parallel to each other, one end articulates on material platform 3 and the other end and 5 eccentric articulated transfer line 6 of carousel, fixed cover is established at the worm wheel 7 on pivot 4, rotate the worm 8 of connecting on fuselage 2 and with worm wheel 7 meshing, and install the motor 9 that is used for rotatory worm 8 on the fuselage 2, motor 9 passes through the electric wire and is connected with the power. Wherein, the worm wheel 7, the worm 8 and the motor 9 form a power mechanism. The staff opens motor 9 and rotates worm 8, and worm wheel 7 and pivot 4 will take place rotatoryly, and two carousel 5 at 4 both ends of pivot just can follow pivot 4 rotatoryly, and carousel 5 drives the one end of transfer line 6 and revolves 4 rotations of pivot, and the other end of transfer line 6 just can drive material platform 3 reciprocating rotation. When the material table 3 with the paper board is rotated to the position closest to the fixed plate, the die-cutting knife on the fixed plate can press out cutting marks on the paper board, and the die-cutting processing of the paper board is further completed. When material platform 3 rotated again and separated with the fixed plate, the staff can take off the cardboard from material platform 3.

Referring to fig. 2 and 3, a sliding groove 10 is formed in the side wall, away from the body 2, of the rotary table 5, the length direction of the sliding groove 10 is the same as the radius direction of the rotary table 5, a sliding block 11 is tightly attached to the sliding groove 10 in a sliding mode, a threaded rod 12 which is the same as the length direction of the sliding groove 10 is further connected to the sliding groove 10 in a rotating mode, and the threaded rod 12 penetrates through the sliding block 11 and is in threaded fit with the sliding block 11. One end of the threaded rod 12, which is far away from the axis of the rotating disc 5, penetrates through the sliding groove 10 and is connected with a hand crank 13. The transmission rod 6 comprises an outer rod 14 which is rotatably connected to the sliding block 11 and the cross section of which is in a square ring shape, and an inner rod 15 which is embedded in the outer rod 14 in a sliding mode and far away from one end of the sliding block 11, wherein one end, far away from the outer rod 14, of the inner rod 15 is hinged to the material table 3. The outer rod 14 is also provided with a locking assembly 16 for locking the position of the inner rod 15. Wherein, threaded rod 12 and crank 13 constitute drive assembly, and spout 10, slider 11 and drive assembly have constituted adjustment mechanism.

When the rotation stroke of material platform 3 needs to be adjusted, the staff comes rotatory threaded rod 12 through crank 13, under the combined action of screw thread traction and spout 10 position constraint, slider 11 will slide in spout 10, and outer pole 14 is close to the turning radius of slider 11 one end on carousel 5 and just can change, and interior pole 15 drives the reciprocal pivoted angle of material platform 3 and will change to the realization is to the regulation of material platform 3 rotation stroke. When the slider 11 is close to the axis of rotation of the turntable 5 and moves, the reciprocating rotation angle of the material table 3 becomes small, the cutting mark pressed out by the die-cutting rule on the paperboard becomes shallow, and when the slider 11 moves towards the direction far away from the axis of rotation of the turntable 5, the reciprocating rotation angle of the material table 3 becomes large, and the cutting mark pressed out by the die-cutting rule on the paperboard becomes deep. Before the position of slider 11 is adjusted to rotatory threaded rod 12, the staff took off earlier the locking effect of locking Assembly 16 to interior pole 15 position, and two interior poles 15 of 2 both sides of fuselage will no longer receive the restraint with material platform 3, and the staff and then can rotate the threaded rod 12 of fuselage 2 one side threaded rod 12 time rotatory opposite side again, need not the staff and come the threaded rod 12 of rotatory both sides simultaneously, makes things convenient for staff's operation.

Referring to fig. 3, the locking assembly 16 includes a socket 161 formed on the outer rod 14 and communicating the inner and outer sidewalls of the outer rod 14, a threaded hole 162 formed on the inner rod 15 and facing the socket 161 during sliding of the inner rod 15, and a bolt 163 passing through the socket 161 and threadedly coupled in the threaded hole 162. The bolt 163 is further sleeved with a spring washer 17 for preventing the bolt 163 from loosening, and the spring washer 17 is located between the head of the bolt 163 and the outer side wall of the outer rod 14. The staff rotates bolt 163 and makes it break away from screw hole 162, and outer pole 14 and interior pole 15 alright relative slip, and after the position adjustment of slider 11 was ended, the staff slides interior pole 15 again and makes screw hole 162 just to jack 161, then rotates bolt 163 and makes bolt 163 screw in screw hole 162, and the position of interior pole 15 is just locked.

Referring to fig. 2, in the rotation process of the rotary disk 5, in order to avoid shaking of the hand crank 13 to enable the threaded rod 12 to rotate, the threaded rod 12 and the hand crank 13 are movably connected. One end of the threaded rod 12 extending out of the sliding groove 10 is provided with a slot 18, the cross section of the slot 18 is rectangular, and the crank 13 is fixedly connected with an insertion block 19 which is in insertion fit with the slot 18. When the threaded rod 12 needs to be rotated, a worker inserts the insertion block 19 on the hand crank 13 into the insertion groove 18 on the threaded rod 12.

The side wall of the rotary table 5 far away from the machine body 2 is provided with a scale 20, and the scale 20 is used for displaying the distance between the slide block 11 and the rotary axis of the rotary table 5. Scale 20 provides the reference for the slider 11 that slides is come to staff's rotatory threaded rod 12, not only makes the staff slider 11 that slides can be more accurate, makes the distance that the slider 11 of fuselage 2 both sides slided moreover can keep the same, and the adjustment of material platform 3 rotation stroke will be faster and smooth.

Referring to fig. 1, a support rod 21 for supporting the material table 3 is rotatably connected to the base 1. After the inner rod 15 is separated from the outer rod 14, the material table 3 can freely rotate without being constrained, a worker can rotate the support rod 21 to temporarily support the material table 3, the operation of supporting the material table 3 when the worker adjusts the position of the sliding block 11 is omitted, and the worker can conveniently rotate the threaded rod 12.

The implementation principle of the embodiment is as follows: when the rotation stroke of material platform 3 needs to be adjusted, the staff comes rotatory threaded rod 12 through crank 13, under the combined action of screw thread traction and spout 10 position constraint, slider 11 will slide in spout 10, and outer pole 14 is close to the turning radius of slider 11 one end on carousel 5 and just can change, and interior pole 15 drives the reciprocal pivoted angle of material platform 3 and will change to the realization is to the regulation of material platform 3 rotation stroke. When the slider 11 is close to the axis of rotation of the turntable 5 and moves, the reciprocating rotation angle of the material table 3 becomes small, the cutting mark pressed out by the die-cutting rule on the paperboard becomes shallow, and when the slider 11 moves towards the direction far away from the axis of rotation of the turntable 5, the reciprocating rotation angle of the material table 3 becomes large, and the cutting mark pressed out by the die-cutting rule on the paperboard becomes deep.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
