Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses a roll change mechanism of roller print decorator, including frame 1, axis of rotation 6 and conversion frame 4, the equal vertical recess 2 of having seted up in frame 1 both sides, axis of rotation 6 spanes two recess 2 tops, axis of rotation 6 and conversion frame 4 center fixed connection. A plurality of checkered rollers 3 are arranged on the circumferential direction of the rotating shaft 6, in the embodiment, the number of the checkered rollers 3 is 3, the checkered rollers 3 rotate to be opposite to the grooves 2 and can enter the grooves 2, and a driving assembly for driving the conversion frame 4 to ascend and descend is arranged on the side wall of the rack 1. The decorative pattern roller 3 rotates and is connected on the conversion frame 4, during operation conversion frame 4 gets into recess 2 conflict location near 3 one side of decorative pattern roller, 3 tip of decorative pattern roller have gear 5, there is power device (not shown in the figure) that drives decorative pattern roller 3 through gear 5 in the frame 1, when the easy trouble takes place in the working process of decorative pattern roller 3 needs to repair or change, drive assembly will convert 4 company's decorative pattern rollers 3 of frame and rise to recess 2 top, rethread rotation axis of rotation 6 makes another decorative pattern roller 3 replace the position of trouble decorative pattern roller 3, when reserve decorative pattern roller 3 rotates conversion frame 4 downside and just to recess 2, make conversion frame 4 descend to in the recess 2 through drive assembly, just accomplish the change process and can continue normal operating machine. The checkered roller 3 does not need to be taken out by disassembling the frame 1 in the replacement process of the checkered roller 3, and has the advantage of being convenient to maintain or replace.

Specifically, drive assembly includes screw rod 9, motor 8, 1 outer wall lower part fixedly connected with mounting bracket 7 in lifter plate 11 and the push rod 12 frame, screw rod 9 rotates to be connected on

mounting bracket

7, 8 fixed connection of motor are in

mounting bracket

7, 8's pivot drive screw rod 9 rotates, be close to on the mounting bracket 7 of screw rod 9 vertical fixedly connected with

guide bar

10, 11 horizontal threaded connection of lifter plate slides on screw rod 9 and with the vertical direction of guide bar 10 and is connected, vertical fixedly connected with push rod 12 on the

lifter plate

11, 12 upper ends fixedly connected with lifter ring 16 of push rod, lifter ring 16 is connected with the coaxial rotation of dwang. The motor 8 drives the screw rod 9 to rotate, the lifting plate 11 is connected to the guide rod 10 in a sliding mode and cannot rotate along with the screw rod 9, and the lifting plate 11 rises or falls in the vertical direction along with different rotation directions of the screw rod 9 under the action of threads.

Further, two guide rods 10 are provided, and the two guide rods 10 are arranged on two sides of the screw 9 in parallel. The two guide rods 10 are arranged on the two sides of the screw 9, so that the two ends of the lifting plate 11 are stressed more uniformly and more stably during lifting.

Further, a worm wheel 19 is rotatably connected in the mounting frame 7, the screw 9 penetrates through the mounting frame 7 and is coaxially and fixedly connected with the worm wheel 19, a worm 20 is meshed on one side of the worm wheel 19, the worm 20 is rotatably connected to the mounting frame 7, and a rotating shaft of the motor 8 is coaxially and fixedly connected with the worm 20. The motor 8 drives the screw rod 9 to rotate through the worm wheel 19 and the worm 20, the self-locking function is achieved, the worm 20 can drive the worm wheel 19 to rotate, so that the conversion frame 4 is driven to lift, when the conversion frame 4 reaches the required height, the conversion frame 4 does not slide any more after the motor 8 is closed because the worm wheel 19 cannot drive the worm 20 to rotate, and a worker can replace or maintain the patterned roller 3 conveniently. Further, the worms 20 on both sides of the frame 1 are coaxially arranged, and a transmission rod 21 is coaxially and fixedly connected between the two worms 20. The worm shafts 20 on the two sides are connected through the transmission rod 21, and the worm shafts 20 on one side can be driven to synchronously rotate, so that the rotating shaft 6 is driven to stably ascend and descend.

Further, a switch box is arranged on the side wall of the rack 1, and a forward rotation switch for controlling the motor 8 to rotate forward and a reverse rotation switch for controlling the motor 8 to rotate reversely are arranged in the switch box. Prevent that staff's maloperation from pressing the switch, be provided with the switch box and play the guard action, the corotation switch setting that switch box the inside control conversion frame 4 rose is at the upside of switch box, and the reversal switch setting that control conversion frame 4 descends is at the downside of switch box, more does benefit to the staff and operates.

Further, rack 1 inside wall is provided with the limiting plate from top to bottom at the interval level, and the lower surface of top limiting plate is provided with first normally closed travel switch 13, and the upper surface of below limiting plate is provided with second normally closed travel switch 17, and first normally closed travel switch 13 is established ties with the corotation switch, and second normally closed travel switch 17 is established ties with the reversal switch, and lifter plate 11 can contradict the disconnection with first normally closed travel switch 13 and second normally closed travel switch 17. When the lifting plate 11 rises to the position suitable for replacing the checkered roller 3, the lifting plate 11 abuts against the first normally closed travel switch 13 to stop the motor 8, the conversion frame 4 automatically stops moving, when the maintenance or replacement of the checkered roller 3 is completed, the lower surface of the lifting plate 11 abuts against the second normally closed travel switch 17 to be disconnected when the conversion frame 4 descends to the bottom of the groove 2, and the conversion frame 4 stops at the bottom of the groove 2. Furthermore, the rocking handle 15 is fixedly connected with the end of the rotating shaft 6, so that workers can rotate the rotating shaft 6 more conveniently, and the pattern roller 3 can be replaced by the rotating conversion frame 4.

The implementation principle of the embodiment is as follows: when the checkered roller 3 needs to be maintained, the screw rod 9 is driven to rotate through the motor 8, the lifting plate 11 moves upwards along the guide rod 10, the push rod 12 and the lifting ring 16 push the rotating shaft 6 to move upwards, after the conversion frame 4 is completely separated from the groove 2, the standby checkered roller 3 can be rotated to the lower side of the conversion frame 4 by the rotation conversion frame 4 to replace the checkered roller 3 needing to be maintained, finally, the conversion frame 4 is driven by the driving assembly to stably descend to the bottom of the groove 2, and the replacement of the checkered roller 3 is completed, so that the roller printing and decorating machine can continue to normally operate.

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.
