Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] This utility model provides, for example Figures 1-5 The diagram shows a slitting mechanism.
[0029] The device includes multiple die-cutting blades 100, clamping mechanisms, and a main shaft 114. The die-cutting blades 100 are arranged in parallel and spaced intervals. The clamping mechanisms are located on both sides of each die-cutting blade 100 and are used to clamp and fix the die-cutting blades 100. The main shaft 114 is fixedly located at the end of the outermost clamping mechanism and is used to connect the multiple die-cutting blades 100 to the slitting device. Each die-cutting blade 100 is clamped on both sides by the clamping mechanisms, and the clamping mechanisms between adjacent die-cutting blades 100 are coaxially connected and cooperate with the main shaft 114. The connecting mechanism can form a complete slitting mechanism. This slitting mechanism can be installed on the bearing seat on the frame of the slitting device via the main shaft 114, so that the slitting mechanism can complete the slitting process of cigarette tipping paper by rotation. Moreover, since the clamping mechanism can be unlocked, it can meet the requirement of disassembling and replacing individual die-cutting blades 100 individually, without having to remove the entire slitting mechanism from the frame before replacing the die-cutting blades 100. This makes the replacement operation of the die-cutting blades 100 more convenient, thereby improving the convenience and efficiency of disassembling and assembling the die-cutting blades 100 on the slitting mechanism.
[0030] The clamping mechanism includes a first cutter holder 101 and a second cutter holder 102. The first cutter holder 101 is disposed on one side of the die-cutting blade 100, and a first polygonal shaft 103 is fixedly connected to the side of the first cutter holder 101 opposite to the die-cutting blade 100. The second cutter holder 102 is disposed on the other side of the die-cutting blade 100, and a second polygonal shaft 104 is slidably connected to the side of the second cutter holder 102 opposite to the die-cutting blade 100. A return spring 113 is fixedly connected between the second polygonal shaft 104 and the second cutter holder 102. An auxiliary lever ring 109 is fixedly sleeved on the end of the outer wall of the second cutter holder 102 away from the die-cutting blade 100. A telescopic groove 110 is formed inwardly at the end of the second cutter holder 102 facing the second polygonal shaft 104. The two ends of the return spring 113 are fixedly connected to the opposite sides of the second polygonal shaft 104 and the telescopic groove 110, respectively. The second polygonal shaft 104 is located away from the second cutter holder 102. One end is fixedly connected to one end of the first polygonal shaft 103 at an adjacent position. Both the first polygonal shaft 103 and the second polygonal shaft 104 are polygonal columnar bodies. Through the elastic thrust provided by the return spring 113, the second cutter holder 102 and the first cutter holder 101 cooperate to clamp the die-cutting blade 100 between the first cutter holder 101 and the second cutter holder 102. It can also rotate synchronously with the first cutter holder 101 and the second cutter holder 102, thereby meeting the needs of installing and fixing the die-cutting blade 100 and disassembling it separately. Moreover, during the disassembly process, it is only necessary to axially move the second cutter holder 102 away from the die-cutting blade 100 to release the clamping force of the second cutter holder 102 and the first cutter holder 101 on the die-cutting blade 100, so that the die-cutting blade 100 can be directly taken out from the position between the second cutter holder 102 and the first cutter holder 101, thereby making the disassembly of the die-cutting blade 100 more convenient.
[0031] Furthermore, a fixing block 111 is fixedly connected to the end face of the second tool holder 102 at a position on the outer periphery of the telescopic slide groove 110. A clamping bolt 112 is threadedly connected to the middle of the fixing block 111. There are two spindle bodies 114. One spindle body 114 is fixedly connected to one end of the first polygonal shaft 103 at the outermost position, and the other spindle body 114 is fixedly connected to one side of the second polygonal shaft 104 at the outermost position. The outer wall of the second polygonal shaft 104 can be axially spaced with multiple positioning holes that match the ends of the clamping bolts 112, so that the clamping bolts 112 can be threadedly connected to the fixing block 111, allowing the clamping bolts 112 to rotate during operation. The second cutter head 102 can move closer to or further away from the second polygonal shaft 104. After the second cutter head 102 and the first cutter head 101 have secured the die-cutting blade 100, the clamping bolt 112 is rotated and inserted into the positioning hole at the corresponding position on the outer wall of the second polygonal shaft 104. This can limit the axial movement of the second cutter head 102, ensuring the stability of the clamping of the die-cutting blade 100 by the second cutter head 102 and the first cutter head 101. This prevents the first cutter head 101 and the second cutter head 102 from loosening due to the centrifugal force of rotation, which would cause unstable clamping of the die-cutting blade 100 and affect the slitting quality of the cigarette splicing paper by the die-cutting blade 100.
[0032] In Example 2, based on Example 1, a main positioning hole 108 is provided in the middle of the side of the first cutter holder 101 facing the die-cutting blade 100, and a main positioning pin 106 is fixedly connected to the middle of the side of the second cutter holder 102 facing the die-cutting blade 100. The outer wall of the main positioning pin 106 is slidably connected to the inner wall of the main positioning hole 108. When the first cutter holder 101 and the second cutter holder 102 clamp the die-cutting blade 100, the main positioning pin 106 passes through the die-cutting blade 100 and is inserted into the main positioning hole 108 to position the die-cutting blade 100. This ensures that the die-cutting blade 100 is concentrically installed between the first cutter holder 101 and the second cutter holder 102, thereby improving the accuracy and convenience of the die-cutting blade 100 installation and positioning, improving the installation precision of the die-cutting blade 100, and thus helping to improve the cutting quality of cigarette splicing paper by the die-cutting blade 100. The die-cutting blade 100 has a positioning through hole in the middle that matches the main positioning pin 106.
[0033] Furthermore, a plurality of secondary positioning pins 105, fixed to the outer wall of the second cutter holder 102, are arranged in a ring array on the outer periphery of the main positioning pin 106. A plurality of secondary positioning holes 107 are arranged in a ring array on the outer periphery of the main positioning hole 108 on the outer wall of the first cutter holder 101. The outer wall of the secondary positioning pins 105 is slidably connected to the inner wall of the secondary positioning holes 107. After the multiple secondary positioning pins 105 pass through the die-cutting blade 100, they are inserted into the corresponding secondary positioning holes 107, which satisfies the radial limitation of the die-cutting blade 100, allowing the die-cutting blade 100 to rotate radially between the first cutter holder 101 and the second cutter holder 102. The direction of rotation is used for limiting, so that the first cutter holder 101, the second cutter holder 102 and the die-cutting blade 100 can maintain synchronous and unidirectional rotation, improving the installation quality and stability of the die-cutting blade 100. At the same time, multiple limiting through holes that match the secondary positioning pins 105 need to be opened on the die-cutting blade 100, so that when the second cutter holder 102 and the first cutter holder 101 clamp the die-cutting blade 100, the secondary positioning pins 105 can pass through the die-cutting blade 100 and be inserted into the secondary positioning holes 107 on the first cutter holder 101, thereby making the installation of the die-cutting blade 100 between the first cutter holder 101 and the second cutter holder 102 more stable.
[0034] A cigarette tipping paper slitting device includes the aforementioned slitting mechanism.
