[0036] The control system is electrically connected with the first paper receiving platform 1, the second paper receiving platform 2, the auxiliary supporting mechanism 3 and the driving mechanism, and is used for action coordination and timing control; in the scheme, the control system obtains the paper stack height, platform position and other information in real time through the sensor, controls the first paper receiving platform 1 to descend, the supporting block 32 to insert, the supporting plate 34 to support and the paper stack to transfer according to the logical judgment, and ensures that the die cutting machine can continuously output paper and the paper stack is neat.

[0037] Embodiment 2:

[0038] The support 31 is arranged in a frame structure and surrounds the upper side of the first paper receiving platform 1, and the paper output by the die cutting machine can pass through the inside of the support 31 during the stacking process.

A gap is provided between adjacent two conveying belts. The plurality of support blocks 32 and the support plate 34 can be embedded into the gap when the first paper collection platform 1 and the auxiliary support mechanism 3 are handed over during movement.

[0051] In this embodiment, the gap width is 5 cm. After the first paper collection platform 1 transfers the first batch of paper stacks to the second paper collection platform 2, the first paper collection platform 1 is reset. When the first paper collection platform 1 abuts to the second batch of paper during the resetting process, the support blocks 32 and the support plate 34 located at the bottom of the second batch of paper stacks can be embedded into the gap of the first paper collection platform 1, so that the second batch of paper stacks can be directly stacked on the first paper collection platform 1.

[0057] In this embodiment, the controller module is a PLC, which judges the paper stack height, the paper collection platform position and the state of the support 31 according to a preset program, controls the lifting of the first paper collection platform 1, the support of the support 31, the insertion of the support block 32, the slow support of the supporting plate 34 and the transfer of the paper stack, and resets each component, so that the die-cutting machine continuously outputs without interruption and the paper stack is neat and stable.

[0058] Embodiment 9:

[0059] The main purpose of the hybrid transmission type die-cutting paper collection part set is to realize continuous paper collection and stacking at the paper output end of the die-cutting machine, avoid production rhythm interruption caused by paper stack transfer, ensure the neatness and stability of the paper stack, and be suitable for high-speed die-cutting production scenes. The overall working principle can be divided into the following processes:

[0060] S1: Paper stacking to the first paper collection platform 1

[0061] The die-cutting machine continuously outputs paper to the first paper collection platform 1, and the stacked paper stack is the first batch of paper stack. In the initial paper stacking stage, the first paper collection platform 1 is kept raised to the position of the paper output end of the die-cutting machine, so that the paper naturally stacks and falls neatly, prevents tilting or sliding, and gradually increases the height of the first batch of paper stack, and uniformly descends through the first lifting device, but always maintains the highest point of the paper stack at the position of the paper output end.

[0062] S2: The auxiliary supporting mechanism 3 intervenes to support the paper stack

[0063] In the first batch of paper stack stacking stage, the support 31 is kept raised to a position close to the paper output end. When the first batch of paper stack reaches a preset height of 0.5 meters, the multiple support components on the support 31 act simultaneously:

[0064] S2.1: The support block 32 is quickly inserted into the top layer of the first batch of paper stack through the electric push rod 33 to form a temporary supporting layer, so that the subsequent falling paper falls onto the support block 32, and the paper stack stacked from this point is the second batch of paper stack;

[0065] S2.2: The support 31 uniformly lowers the second batch of paper stack through the second lifting assembly, and maintains the same lowering speed as the first paper collection platform 1, so as to ensure that the die-cutting machine does not interrupt the paper output;

[0066] S2.3: The supporting plate 34 slides in the support block 32 and is slowly inserted into the gap between the paper stacks through the gear 36 to increase the contact area with the bottom of the second batch of paper stacks, so as to provide stable support for the second batch of paper stacks.

[0067] S3: The first paper collection platform 1 accelerates to descend, and the paper stack is transferred to the second paper collection platform 2

[0068] In the second batch of paper stacking process, the first paper collection platform 1 accelerates to be lowered to be flush with the second paper collection platform 2, at this time, the conveying belts on the first paper collection platform 1 and the second paper collection platform 2 are started synchronously, and the first batch of paper stacks are transferred from the first paper collection platform 1 to the second paper collection platform 2.

[0069] S4: The first paper collection platform 1 and the auxiliary supporting mechanism 3 are reset and circularly prepared for the next round

[0070] After the first batch of paper stacks are transferred, the first paper collection platform 1 is reset upwards to directly support the bottom of the second batch of paper stacks, at this time, the supporting blocks 32 and the supporting plates 34 are embedded into the gap of the first paper collection platform 1, and the supporting blocks 32 and the supporting plates 34 are withdrawn without disturbing the paper stacks, so that the paper stacks are ensured to be stable, then the bracket 31 is reset to the paper outlet end position through the second batch of paper stacks, and the system is prepared for the next round of paper stacking, when the second batch of paper stacks reaches 0.5 m, the supporting blocks 32 are inserted into the paper stacks again, and the above steps are repeated to realize continuous circulation.

[0071] The above is only an embodiment of the present application, and common technical solutions and / or characteristics in the scheme are not described in detail. It should be noted that, for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
