Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically to a differential speed control mechanism and a winding device containing the mechanism. Background Technology

[0002] A rotary die-cutting machine continuously cuts materials through the rotation of a rotary blade. It mainly consists of three core processes: feeding, die-cutting, and rewinding. The roll material is loaded onto the feeding shaft, and a tension control system maintains uniform material tension to prevent slack or overstretching. The rotary blade rotates at high speed driven by a motor, cutting the material through the gap between the blade and the anvil roller. The blade shape is customized according to the die-cutting pattern. As the blade rotates and the material is conveyed, preset shapes are continuously cut. Finished products and waste are conveyed to the rewind shaft, where tension control ensures proper roll tightness for subsequent processing.

[0003] As per the instruction manual Figure 3 As shown, in traditional technology, the material on the base paper is directly wound up after being die-cut, which results in waste of material between the raw material paper and the mold.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a differential control mechanism and a winding device containing the mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a differential control mechanism and a winding device containing the mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a differential speed control mechanism, including a differential speed control component, the differential speed control component including a new bottom paper unwinding roller, an old bottom paper recycling roller arranged parallel to the side of the new bottom paper unwinding roller, and a rotating shaft coaxially connected to the ends of the new bottom paper unwinding roller and the old bottom paper recycling roller, the rotating shaft corresponding to the new bottom paper unwinding roller being directly connected to the rotating end of a motor, and a tensioning sleeve being fitted on the rotating shaft, a pulley being fitted on the outside of the tensioning sleeve, and a synchronous belt being fitted between the pulleys.

[0007] Furthermore, the expansion sleeve is composed of a conical inner ring and a conical outer ring, and when the bolt is tightened, the inner ring of the expansion sleeve radially contracts to grip the rotating shaft and the outer ring of the expansion sleeve radially expands to support the pulley hub.

[0008] Furthermore, the radius of the pulley fitted on the shaft corresponding to the new bottom paper unwinding roller is smaller than the radius of the pulley fitted on the shaft corresponding to the old bottom paper recycling roller, and the rotation speed of the new bottom paper unwinding roller is higher than that of the old bottom paper recycling roller, thus forming a speed difference.

[0009] Furthermore, the new bottom paper unwinding roller is directly connected to the rotating end of the motor, and the smaller diameter pulley on the new bottom paper unwinding roller is driven to the larger diameter pulley on the old bottom paper recycling roller via a synchronous belt to reduce the rotation speed.

[0010] A winding device incorporating the mechanism is equipped with a differential speed control mechanism as described above, including a die-cutting roller disposed above an old bottom paper recycling roller, a face paper unwinding roller disposed above one side of the die-cutting roller, and a waste material winding roller disposed above the other side of the die-cutting roller.

[0011] Furthermore, a feed roller is provided in the feeding direction of the die-cutting roller, and an old bottom paper unwinding roller is provided on the outside of the feed roller.

[0012] Furthermore, a forming and winding roller is provided in the output direction of the die-cutting roller, and the forming and winding roller is connected to the new bottom paper unwinding roller through a guide roller.

[0013] This utility model provides a differential speed control mechanism and a winding device containing the mechanism, which has the following advantages:

[0014] 1. In this utility model, after the material is die-cut, the old backing paper that carries the waste material is no longer discarded. Instead, it is wound up in the opposite direction by the old backing paper recycling roller to achieve reuse. At the same time, the new backing paper is unwound simultaneously. The die-cut finished material is peeled off from the old backing paper and directly transferred to the surface of the new backing paper. The finished product is then wound up by the forming and winding roller. This new technology solution of the die-cutting device saves the distance between the raw material paper and the die through the coordinated design of recycling the backing paper, differential speed control and material transfer. Its core principle is to use the differential speed ratio to eliminate the material distance in the traditional process, and at the same time reduce the consumption of backing paper by replacing the old and new backing papers.

[0015] 2. In this utility model, the new bottom paper unwinding roller is directly connected to the rotating end of the motor. The smaller diameter pulley on the new bottom paper unwinding roller is driven by a synchronous belt to the larger diameter pulley on the old bottom paper recycling roller at a reduced speed. The speed difference between the new bottom paper unwinding roller and the old bottom paper recycling roller causes the die-cutting material to be accelerated and pulled to the new bottom paper at the moment of peeling, achieving seamless splicing. The pulleys are fastened to the corresponding rotating shafts of the new bottom paper unwinding roller and the old bottom paper recycling roller by the expansion sleeve. The pulleys of different diameters can be quickly replaced by removing and installing screws, and the differential speed adjustment between the two can be achieved by using pulleys with different radius ratios.

Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 2 As shown, a differential control mechanism includes a differential control component 1. The differential control component 1 includes a new bottom paper unwinding roller 101, an old bottom paper recycling roller 102 arranged parallel to the side of the new bottom paper unwinding roller 101, and a rotating shaft 103 coaxially connected to the ends of the new bottom paper unwinding roller 101 and the old bottom paper recycling roller 102. The rotating shaft 103 corresponding to the new bottom paper unwinding roller 101 is directly connected to the rotating end of the motor 104, and a tightening sleeve 105 is sleeved on the rotating shaft 103. A pulley 106 is sleeved on the outside of the tightening sleeve 105, and a synchronous belt 107 is sleeved between the pulleys 106. The tightening sleeve 105 is composed of a conical inner ring and a conical outer ring, and the tightening sleeve is tightened when the bolt is tightened. The inner ring of the expansion sleeve 105 radially contracts to hug the rotating shaft 103 and the outer ring of the expansion sleeve 105 radially expands to support the hub of the pulley 106. The radius of the pulley 106 fitted on the rotating shaft 103 corresponding to the new bottom paper unwinding roller 101 is smaller than the radius of the pulley 106 fitted on the rotating shaft 103 corresponding to the old bottom paper recycling roller 102. The rotation speed of the new bottom paper unwinding roller 101 is higher than that of the old bottom paper recycling roller 102, thus forming a speed difference. The new bottom paper unwinding roller 101 is directly connected to the rotating end of the motor 104. The smaller diameter pulley 106 on the new bottom paper unwinding roller 101 is driven to rotate at a reduced speed to the larger diameter pulley 106 on the old bottom paper recycling roller 102 via the synchronous belt 107.

[0022] The specific operation is as follows: The new bottom paper unwinding roller 101 is directly connected to the rotating end of the motor 104. The smaller diameter pulley 106 on the new bottom paper unwinding roller 101 is driven to the larger diameter pulley 106 on the old bottom paper recycling roller 102 via the synchronous belt 107. The speed difference between the new bottom paper unwinding roller 101 and the old bottom paper recycling roller 102 causes the die-cutting material to be accelerated and pulled to the new bottom paper at the moment of peeling, achieving seamless splicing. The pulley 106 is fastened to the corresponding rotating shaft 103 of the new bottom paper unwinding roller 101 and the old bottom paper recycling roller 102 by the expansion sleeve 105. The pulleys 106 of different diameters can be quickly replaced by removing and installing screws, and the differential speed adjustment between the two can be achieved by using pulleys 106 with different radius ratios.

[0023] A winding device incorporating the aforementioned mechanism is equipped with a differential speed control mechanism, which enables the old backing paper carrying waste material to be reused after die-cutting by rewinding it in reverse via the old backing paper recycling roller 102. Simultaneously, new backing paper is unwound, and the die-cut finished material is peeled off from the old backing paper and directly transferred to the surface of the new backing paper. The finished product is then wound up by the forming winding roller 7. This new technology solution for the die-cutting device achieves savings in the distance between the raw material paper and the die through the coordinated design of backing paper recycling, differential speed control, and material transfer.

[0024] like Figures 1 to 3 As shown, a winding device containing this mechanism includes a die-cutting roller 2, which is disposed on the old bottom paper recycling roller 102. A face paper unwinding roller 3 is disposed above one side of the die-cutting roller 2, and a waste material winding roller 4 is disposed above the other side of the die-cutting roller 2. A feeding roller 5 is disposed in the feeding direction of the die-cutting roller 2, and an old bottom paper unwinding roller 6 is disposed outside the feeding roller 5. A forming winding roller 7 is disposed in the discharging direction of the die-cutting roller 2, and the forming winding roller 7 is connected to the new bottom paper unwinding roller 101 through a guide roller.

[0025] It is worth noting that the technical solution of installing pulley 106 on the drive shaft by means of tightening sleeve screw is to adopt the existing mature quick-release solution of pulley 106. Specifically, the tightening sleeve 105 is composed of a conical inner ring and a conical outer ring. When tightening the bolt, the inner ring of the tightening sleeve 105 radially contracts to hug the rotating shaft 103 and the outer ring of the tightening sleeve 105 radially expands to support the hub of pulley 106, thereby realizing the quick-release process of pulley 106 and thus realizing the differential speed control of the new bottom paper unwinding roller 101 and the old bottom paper recycling roller 102.

[0026] In summary, when using the differential speed control mechanism and the winding equipment containing it, after the material is die-cut, the old backing paper carrying the waste is no longer discarded, but is instead wound in reverse by the old backing paper recycling roller 102 for reuse. Simultaneously, new backing paper is unwound, and the die-cut finished material is peeled off from the old backing paper and directly transferred to the surface of the new backing paper. The forming winding roller 7 then completes the finished product winding. This new die-cutting device's technological solution, through the coordinated design of backing paper recycling, differential speed control, and material transfer, achieves savings in the distance between the raw material paper and the die. Its core principle is to eliminate the material spacing in traditional processes by utilizing the differential speed ratio, while simultaneously reducing backing paper consumption through the replacement of old and new backing paper. The new backing paper unwinding roller 102... 1. Directly connected to the rotating end of the motor 104, the smaller diameter pulley 106 on the new bottom paper unwinding roller 101 is driven by the synchronous belt 107 to the larger diameter pulley 106 on the old bottom paper recycling roller 102 at a reduced speed. The speed difference between the new bottom paper unwinding roller 101 and the old bottom paper recycling roller 102 causes the die-cutting material to be accelerated and pulled to the new bottom paper at the moment of peeling, achieving seamless splicing. The pulley 106 is fastened to the corresponding rotating shaft 103 of the new bottom paper unwinding roller 101 and the old bottom paper recycling roller 102 by the expansion sleeve 105. The pulleys 106 of different diameters can be quickly replaced by removing and installing screws, and the differential speed adjustment between the two can be achieved by using pulleys 106 with different radius ratios.
