Description

Technical Field

[0001] This utility model belongs to the field of slitting wheel technology, specifically a novel second slitting wheel. Background Technology

[0002] A slitting roller is a precision ring-shaped component used to assist in the slitting process of tobacco sheets (such as cigarette paper, tobacco film, tobacco sheets, etc.). It cuts double-length cigarettes into standard single cigarettes, ensuring consistent cigarette length. Its design and function directly serve the stability, accuracy, and material protection of the slitting process. During high-speed operation, the slitting roller needs to accurately slit the continuously conveyed tobacco materials (such as cigarette paper, film) into a set width. The second slitting roller in the cigarette rolling machine is a core functional component in the rolling process. It is responsible for cutting the double-length cigarettes (tobacco segments + double filter tips + tipping paper wrapping) into equal lengths. Its core objective is to ensure that the cut is flat and free of burrs, and that the cigarette length error is ≤0.5mm, meeting the process standards.

[0003] Existing second slitting wheels have certain drawbacks in use. They typically use the limiting grooves and adsorption holes on the slitting wheel body to directly adsorb and fix the semi-finished cigarettes. However, during use, the slitting wheel body is prone to problems such as negative pressure fluctuations or blockage of the adsorption holes, which can cause the semi-finished cigarettes to shift on the slitting wheel body. This can result in cigarettes of uneven lengths after slitting, reducing the yield rate of cigarette production and the effectiveness of the second slitting wheel, thus failing to meet people's needs.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1 Please see Figure 1 - Figure 5This application provides a novel second slitting wheel, comprising: a slitting wheel body 1 and a cutting blade that cooperates with the slitting wheel body 1 to slit semi-finished cigarette products; further comprising: a limiting mechanism disposed on the slitting wheel body 1 and limiting the semi-finished cigarette products; the limiting mechanism includes a gas distribution seat 3 connected to the slitting wheel body 1 and a vacuum adsorption structure 4 disposed on the gas distribution seat 3 and communicating with the slitting wheel body 1; the slitting wheel body 1 is provided with limiting grooves 5 arranged in a circular array to limit the semi-finished cigarette products, and the gas distribution seat 3, the vacuum adsorption structure 4 and the limiting grooves 5 cooperate to limit the semi-finished cigarette products; the limiting mechanism also includes floating ring structures 2 symmetrically disposed on both sides of the slitting wheel body 1 and flexibly clamping the semi-finished cigarette products, the floating ring structures 2 being able to clamp and limit the semi-finished cigarette products.

[0022] In this embodiment, when the slitting wheel is working, the cigarette semi-finished product enters the limiting groove 5 which is arranged in a circular array. The gas distribution seat 3 and the vacuum adsorption structure 4 fix the cigarette semi-finished product in the limiting groove 5 through vacuum adsorption. At the same time, the floating ring structure 2 on both sides flexibly clamps the cigarette semi-finished product. The multiple limiting cooperation ensures that the cigarette semi-finished product is stable in position during the slitting process. Finally, the cutter and the slitting wheel body 1 cooperate to complete the precise slitting.

[0023] This structural design improves the stability and accuracy of the cutting process through multi-dimensional limiting methods, making it particularly suitable for processing fragile semi-finished products such as cigarette sticks, thus reducing losses during processing.

[0024] In this invention, the vacuum adsorption structure 4 includes a vacuum adsorption cavity 7 disposed on the gas distribution seat 3 and several sets of vacuum adsorption holes 8 disposed in the limiting groove 5. The vacuum adsorption cavity 7 is connected to the vacuum adsorption holes 8. The vacuum adsorption cavity 7, as the basic component of vacuum adsorption, is disposed on the gas distribution seat 3 and is the core cavity that generates and provides vacuum adsorption force, providing the power source for the entire adsorption process. The vacuum adsorption cavity 7 and the vacuum adsorption holes 8 are interconnected to form a complete vacuum adsorption path. When the vacuum adsorption cavity 7 generates negative pressure, the negative pressure is transmitted to the limiting groove 5 through the connected vacuum adsorption holes 8, thereby generating adsorption force on the cigarette semi-finished product and firmly fixing it in the limiting groove 5. This design allows the vacuum adsorption force to act precisely on the cigarette semi-finished product. Combined with the structural limiting of the limiting groove 5 and the flexible clamping of the floating ring structure 2, the stability of the cigarette during the cutting process is ensured from multiple dimensions, further improving the cutting accuracy and reducing processing errors and product losses caused by cigarette displacement.

[0025] In this utility model, each end of the slitting wheel body 1 is provided with an installation sleeve 9; the installation sleeve 9 is used to install the float structure 2 to both ends of the slitting wheel body 1 by bolts.

[0026] In this utility model, the floating ring structure 2 includes an inner liner 10 detachably connected to the mounting sleeve 9, a clamping ring 11 for holding the semi-finished cigarette product, and several support members 12 that flexibly connect the clamping ring 11 to the inner liner 10. The clamping ring 11 is evenly distributed on the inner liner 10 and the support members 12. The floating ring structure 2 is coaxially arranged with the slitting wheel body 1, which can stably clamp the semi-finished cigarette product on the slitting wheel body 1, making it easy for the cutter to stably cut the semi-finished cigarette product. The clamping ring 11 is evenly distributed on the inner liner 10 and the support members 12, ensuring that the clamping points of the semi-finished cigarette product are reasonably distributed, avoiding excessive local force or unstable clamping. The floating ring structure 2 is coaxially arranged with the slitting wheel body 1, ensuring that the axis of the semi-finished cigarette product is consistent with the rotation axis of the slitting wheel during the cutting process, providing a basis for precise cutting.

[0027] In this embodiment, when the slitting wheel body 1 adsorbs and fixes the cigarette semi-finished product, the clamping ring 11 clamps and fixes both ends of the cigarette semi-finished product. The floating ring structure 2 cooperates with the evenly distributed clamping ring 11 through the flexibly connected support member 12, which can form a stable and appropriate clamping force on the cigarette semi-finished product. This can not only firmly fix the cigarette on the slitting wheel body 1 to prevent displacement during slitting, but also adapt to the possible slight size differences of the cigarette through the flexibility of the support member 12, avoiding excessive clamping that could cause deformation of the cigarette. Ultimately, this achieves stable slitting of the cigarette semi-finished product by the cutter, improving product processing quality and consistency.

[0028] In this utility model, the main body 1 of the splitting wheel includes at least two drum shafts 13 that are detachable from the air distribution seat 3 and drum rings 14 that are installed on the drum shafts 13 respectively; the limiting groove 5 is formed on the outer wall of the drum ring 14.

[0029] In this utility model, several sets of flat keys 15 connected to the drum ring 14 are installed on the drum shaft 13. The flat keys 15 play the role of transmitting torque and precise positioning, ensuring that the drum shaft 13 and the drum ring 14 rotate synchronously. The drum ring 14 is provided with a keyway connected to the flat key 15. Hexagonal bolts for fixing the drum ring 14 are installed in the limiting groove 5. Several sets of through holes aligned with the vacuum adsorption holes 8 are provided on the drum shaft 13.

[0030] In this utility model, the outer wall of the drum ring 14 is provided with a plurality of removal grooves 16 along the axial direction; removal holes 17 are provided in a circular array in the removal grooves 16.

[0031] In this utility model, an air pipe connector 18 is provided on the outer wall of one end of the air distribution seat 3; a flange 6 is provided on the other end of the air distribution seat 3. The flange 6 is located at the other end of the air distribution seat 3 and is used to fix the entire slitting wheel structure to other parts of the equipment to ensure the overall stability of the slitting wheel during operation.

[0032] In this embodiment, the drum shaft 13 and the drum ring 14 are aligned, and the drum ring 14 is fixed to the drum shaft 13 by the cooperation of the hex bolt and the key 15. The slitting wheel body 1 is installed on the valve seat 3, and the float ring structure 2 is installed on the slitting wheel body 1. In use, the drum ring 14 picks up the semi-finished cigarette and allows it to enter the limiting groove 5. The vacuum adsorption chamber 7 and the vacuum adsorption hole 8 work together to adsorb and limit the semi-finished cigarette. The clamping ring 11 clamps and limits both ends of the semi-finished cigarette. The cutting wheel body 1 rotates and drives the semi-finished cigarette to the cutting blade, so that the cutting blade cuts the semi-finished cigarette.

[0033] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
