Description

Technical Field

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

[0002] In the die-cutting process, wide raw materials need to be divided into narrow rolls that meet the die-cutting width by a slitting blade. This provides standardized input for the die-cutting process. Slitting can remove the printing registration mark area on the edge of the material, reduce the ineffective cutting area of ​​the die-cutting blade, and avoid excessive wear of the blade caused by large-area continuous cutting.

[0003] Traditional slitting blades use a screw-tightening sleeve to secure the disc blade to the blade holder. When it is necessary to adjust the spacing or the number of cuts, it is necessary to adjust them one by one, which is quite troublesome.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a slitting mechanism and a die-cutting machine containing the mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a slitting mechanism and a die-cutting machine 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 slitting mechanism, comprising a slitting assembly, the slitting assembly including a turntable disposed at an end, a driven pulley coaxially connected to the middle of the outer side of the turntable, and an array of grooves arranged on the inner side of the turntable, with corresponding axle segments arranged in an array on the inner side of the grooves, and a slitting blade axially sleeved on the outer side of the axle segment array, with outer wedges fixed at equal intervals along the length direction on the inner wall of the axle segment, and a telescopic rod axially arranged inside the axle segment array, with inner wedges fixed at equal intervals along the length direction on the outer wall of the telescopic rod, and an end plate fixedly connected to the end of the telescopic rod, with a telescopic drive component bolted to the outer side of the end plate.

[0007] Furthermore, the telescopic drive component's telescopic end is fixedly connected to the telescopic rod, and the inner wedge block on the outer wall of the telescopic rod abuts against the outer wedge block's conical surface at the corresponding position on the inner wall of the shaft flap.

[0008] Furthermore, the axial lobe array is rotatably mounted between the recesses at the top of the mounting base, and adjustable brackets are mounted on both sides of the mounting base, with tensioning wheels rotatably mounted between the opposing adjustable brackets.

[0009] Furthermore, a shelf is fixedly installed in the middle of the mounting base, and an anvil roller is installed on the shelf. The anvil roller cooperates with the slitting knife to cut the material.

[0010] Furthermore, a motor is provided below the shelf, and the rotating end of the motor drives the pulley to be connected to the driven pulley via a synchronous belt.

[0011] A die-cutting machine containing the mechanism is equipped with the slitting mechanism as described above, including a die-cutting mechanism. A slitting blade is provided at the front end of the die-cutting mechanism process, and a die-cutting circular blade is provided at the rear end of the die-cutting mechanism process. An unwinding roller is provided at the feeding end of the die-cutting circular blade, and a take-up roller is provided at the output end of the die-cutting circular blade.

[0012] This utility model provides a slitting mechanism and a die-cutting machine containing the mechanism, which has the following beneficial effects: 1. In use, the axle array is sleeved on the outside of the telescopic rod. In the retracted state, the outer diameter of the axle array is smaller than the inner diameter of the slitting blade. This allows the slitting blade to move axially outside the axle array to adjust the slitting spacing or the number of cuts. After adjustment, the telescopic drive pulls the telescopic rod back, and the inner wedge block on the outer wall of the telescopic rod abuts against the conical surface of the outer wedge block at the corresponding position on the inner wall of the axle. This causes the axle array to expand and clamp the slitting blade. In use, the motor's rotating end drives the pulley to be connected to the driven pulley via a synchronous belt. This drives the axle array to rotate through the inner groove of the turntable. The material is then cut in cooperation with the anvil roller and the slitting blade. By setting the slitting components, the slitting spacing or the number of cuts can be adjusted in batches, making it more practical. 2. When in use, by adjusting the slitting spacing and slitting quantity of the slitting blade array, the die-cutting mechanism of this application can divide the material into narrow rolls that conform to the die-cutting width, which facilitates the subsequent precise secondary processing by the die-cutting circular blade, reduces the ineffective cutting area of ​​the die-cutting circular blade, and avoids excessive wear of the blade caused by large-area continuous cutting.

[0015] 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.

[0016] like Figures 2 to 3 As shown, a slitting mechanism includes a slitting assembly 1. The slitting assembly 1 includes a turntable 101 disposed at one end. A driven pulley 102 is coaxially connected to the middle of the outer side of the turntable 101. The inner side of the turntable 101 is provided with an array of grooves 103. Shaft segments 104 are arranged in an array on the inner side of the grooves 103. A slitting blade 105 is axially sleeved on the outer side of the array of shaft segments 104. Outer wedges 106 are fixed at equal intervals along the length direction on the inner wall of the shaft segments 104. A telescopic rod 107 is axially disposed inside the array of shaft segments 104. Inner wedges 108 are fixed at equal intervals along the length direction on the outer wall of the telescopic rod 107. An end plate 109 is fixedly connected to the end of the telescopic rod 107. Bolts are fixed to the outer side of the end plate 109. The telescopic drive component 110 is fixedly connected to the telescopic rod 107 at its telescopic end. The inner wedge block 108 on the outer wall of the telescopic rod 107 abuts against the conical surface of the outer wedge block 106 on the inner wall of the shaft lobe 104. The shaft lobe 104 is rotatably mounted between the top recesses of the mounting base 2. Adjustable brackets 3 are mounted on both sides of the mounting base 2, and tensioning wheels 4 are rotatably mounted between the opposing adjustable brackets 3. A shelf 5 is fixedly mounted in the middle of the mounting base 2, and an anvil roller 6 is mounted on the shelf 5. The anvil roller 6 cooperates with the slitting knife 105 to cut the material. A motor 7 is provided below the shelf 5, and the rotating end of the motor 7 drives the pulley to be connected to the driven pulley 102 through the synchronous belt 8.

[0017] The specific operation is as follows: The array of axle segments 104 is sleeved on the outside of the telescopic rod 107. In the retracted state, the outer diameter of the array of axle segments 104 is smaller than the inner diameter of the slitting blade 105. This allows the slitting blade 105 to move axially outside the array of axle segments 104 to adjust the slitting spacing or the number of slitting operations. After adjustment, the telescopic drive 110 pulls the telescopic rod 107 back, and the inner wedge block 108 on the outer wall of the telescopic rod 107 abuts against the conical surface of the outer wedge block 106 at the corresponding position on the inner wall of the axle segments 104. This allows the shaft flap 104 array to expand and clamp the slitting blade 105. In use, the rotating end of the motor 7 drives the pulley to be connected to the driven pulley 102 via the synchronous belt 8, and then drives the shaft flap 104 array to rotate via the inner slide groove 103 of the turntable 101. In turn, the material is cut by the cooperation of the anvil roller 6 and the slitting blade 105. By setting the slitting component 1, the slitting spacing or the number of slitting operations of the slitting blade 105 can be adjusted in batches, making it more practical.

[0018] A die-cutting machine containing the above-mentioned slitting mechanism is provided. By adjusting the slitting spacing and slitting quantity of the slitting blade array 105, the die-cutting mechanism 9 of this application can divide the material into narrow rolls that conform to the die-cutting width, which facilitates the subsequent precise secondary processing by the die-cutting circular blade 10, reduces the ineffective cutting area of ​​the die-cutting circular blade 10, and avoids excessive wear of the blade caused by large-area continuous cutting.

[0019] like Figure 1 As shown, a die-cutting machine containing the mechanism includes a die-cutting mechanism 9. A slitting blade 105 is provided at the front end of the die-cutting mechanism 9, and a die-cutting circular blade 10 is provided at the rear end of the die-cutting mechanism 9. An unwinding roller 11 is provided at the feeding end of the die-cutting circular blade 10, and a winding roller 12 is provided at the output end of the die-cutting circular blade 10.

[0020] In summary, in use, the slitting mechanism and the die-cutting machine containing this mechanism have the shaft flap 104 array sleeved outside the telescopic rod 107. In the retracted state, the outer diameter of the shaft flap 104 array is smaller than the inner diameter of the slitting blade 105. This allows the slitting blade 105 to move axially outside the shaft flap 104 array to adjust the slitting spacing or the number of cuts. After adjustment, the telescopic drive 110 pulls the telescopic rod 107 back, and the inner wedge block 108 on the outer wall of the telescopic rod 107 abuts against the conical surface of the corresponding outer wedge block 106 on the inner wall of the shaft flap 104. This causes the shaft flap 104 array to expand, achieving an internal clamping effect on the slitting blade 105. In use, the rotating end of the motor 7 drives the pulley through... The synchronous belt 8 is connected to the driven pulley 102 for transmission, and then drives the array of shaft petals 104 to rotate through the inner slide groove 103 of the turntable 101. Then, the material is cut in cooperation with the anvil roller 6 and the slitting blade 105. By setting the slitting component 1, the slitting spacing or the number of slitting blades 105 can be adjusted in batches, which makes it more practical. By adjusting the slitting spacing and the number of slitting blades 105 array, the die-cutting mechanism 9 of this application can divide the material into narrow rolls that meet the die-cutting width, which facilitates the subsequent precise secondary processing of the die-cutting circular blade 10, reduces the ineffective cutting area of ​​the die-cutting circular blade 10, and avoids the excessive wear of the blade caused by large-area continuous cutting.
