Description

Technical Field

[0001] This utility model relates to the field of tobacco equipment technology, and in particular to a cigarette auxiliary material sampling device. Background Technology

[0002] In the cigarette production process, the quality of cigarette auxiliary materials directly determines the quality of the finished cigarettes. The sampling process for inspecting auxiliary materials upon warehousing is a key prerequisite for quality control. The standardization, accuracy, and efficiency of sampling directly affect the reliability of quality inspection data and the efficiency of production flow.

[0003] Cigarette paper, tipping paper, frame paper, or inner lining paper are usually rolled into discs. Currently, when sampling discs of these materials, ordinary paper cutters are commonly used for cutting, which has the following technical drawbacks:

[0004] Firstly, the sampling thickness accuracy is difficult to control, which can easily lead to material waste. Ordinary paper cutters cannot accurately control the sampling thickness. When the cutting force is insufficient, the thickness of the paper stack of the sample cannot meet the standard requirements, and multiple recuts are required. This not only increases the number of operation steps, but may also cause damage to the sample edges due to multiple cuts, affecting subsequent testing. When the cutting force is too large, the sample thickness far exceeds the standard value, resulting in a large amount of waste of auxiliary materials. At the same time, excessive sample thickness will interfere with the accurate measurement of the physical properties of auxiliary materials (such as air permeability and stiffness) during the testing process, leading to distorted quality inspection data and affecting the accuracy of the quality inspection data for this batch of auxiliary materials.

[0005] Secondly, the sampling process is cumbersome, labor-intensive, and inefficient. According to the quality inspection standards, three roll samples need to be taken for each batch, and each sample needs to be cut into three pieces. The thickness of each piece of paper stack is not less than 10mm. The whole process requires two people to work together to complete the paper roll fixing, positioning, and cutting processes. The steps are complicated and the workload is large. A single sampling with a regular paper cutter takes an average of 25 minutes. Moreover, the sampling locations are scattered in warehouses, loading and unloading temporary storage areas, etc., which means that the sampling time for disc-shaped auxiliary materials accounts for more than 80% of the total sampling time, which seriously affects the progress of quality inspection work.

[0006] Therefore, there is an urgent need to develop a cigarette additive sampling device to solve the above problems. Utility Model Content

[0036] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can be a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0041] like Figures 1-3 As shown, this embodiment provides a cigarette auxiliary material sampling device for cutting and sampling a paper tray 100. The cigarette auxiliary material sampling device includes a frame 1, a positioning mechanism 2, and a cutting mechanism 3. The positioning mechanism 2 includes a bearing component 21 and a pressing component 22. The bearing component 21 is mounted on the frame 1 and is used to bear the paper tray 100. The pressing component 22 is adjustablely connected to the frame 1 along the Z-axis and is used to press the paper tray 100 onto the bearing component 21. The cutting mechanism 3 includes a mounting frame 31, a cutting blade 32, a thickness adjustment component 33, and a cutting component 34. The cutting component 34 is mounted on the frame 1, and its output end is drivenly connected to the mounting frame 31. The thickness adjustment component 33 is mounted on the mounting frame 31, and its output end is drivenly connected to the cutting blade 32 and is used to drive the cutting blade 32 to move along the Z-axis. The cutting component 34 can drive the mounting frame 31 to move along the X-axis so that the cutting blade 32 cuts into the paper tray 100.

[0042] During sampling, the paper tray 100 is first placed on the support component 21, and the position of the clamping component 22 along the Z-axis is adjusted until the clamping component 22 presses the paper tray 100 firmly onto the support component 21, wherein the axis of the paper tray 100 is arranged along the X-axis. Next, the cutting blade 32 is driven to move along the Z-axis by the thickness adjustment component 33 so that the cutting blade 32 reaches the preset sampling thickness. Finally, the cutting blade 32 is driven to move along the X-axis by the thickness adjustment component 34, so that the cutting blade 32 cuts into the paper tray 100 fixed on the support component 21 until the cutting blade 32 cuts through the paper tray 100 along the X-axis, thereby obtaining the required sample.

[0043] By employing the aforementioned cigarette auxiliary material sampling device, the thickness adjustment component 33 precisely adjusts the cutting thickness of the cutting blade 32, achieving precise control of the sampling thickness and thus reducing auxiliary material waste. Furthermore, the paper tray 100 is fixed by the carrying component 21 and the clamping component 22, enabling operators to complete the sampling operation by a single person, simplifying the operation process and reducing the difficulty and labor intensity of operation. In addition, the cigarette auxiliary material sampling device can reduce the sampling time from more than 25 minutes to within 10 minutes, significantly improving sampling efficiency.

[0044] like Figure 1 and Figure 2 As shown, in some optional embodiments, the carrier component 21 includes a first driving member and a first carrier component 211 and a second carrier component 212 spaced apart along the Y-axis. The first carrier component 211, the second carrier component 212 and the pressing component 22 form a three-point limit for the paper tray 100. The first driving member is used to drive the first carrier component 211 and the second carrier component 212 to move away from or closer to each other, so as to adapt to the limit requirements of paper trays 100 with different diameters and improve the versatility and practicality of the cigarette auxiliary material sampling device.

[0045] Specifically, the first driving component includes a first handwheel 213, a first lead screw 214, a first nut block 215, and a second nut block 216. The first lead screw 214 extends along the Y-axis. The first handwheel 213 is coaxially connected to the first lead screw 214. The first nut block 215 and the second nut block 216 are both helically engaged with the first lead screw 214. The helical directions of the first nut block 215 and the second nut block 216 are opposite, and one of them is fixedly connected to the first nut block 215, while the other is fixedly connected to the second nut block 216. Since the helical directions of the first nut block 215 and the second nut block 216 are opposite, when the handwheel is rotated, the first nut block 215 and the second nut block 216 move in opposite directions simultaneously, thereby driving the first bearing member 211 and the second bearing member 212 to move away from or closer to each other. This adjustment method keeps the centerline position of the first bearing member 211 and the second bearing member 212 unchanged, that is, keeps the axis position of the paper tray 100 unchanged. This helps to ensure the stability of the sampling and cutting position and avoids changes in the shape or size of the cut sample due to the displacement of the axis of the paper tray 100.

[0046] Among them, the X-axis, Y-axis and Z-axis are mutually perpendicular.

[0047] Of course, in other embodiments, the first driving member includes, but is not limited to, a cylinder or hydraulic cylinder that is pulverizedly connected to the first carrier 211 or the second carrier 212, and can also drive the first carrier 211 and the second carrier 212 to move away from or closer to each other, which is not limited here.

[0048] Furthermore, the supporting assembly 21 also includes a first guide member 217, a first sliding member 218, and a second sliding member 219. The first guide member 217 is arranged parallel to the first lead screw 214. Both the first sliding member 218 and the second sliding member 219 are slidably engaged with the first guide member 217. One of the first sliding member 218 and the second sliding member 219 is fixedly connected to the first nut block 215, and the other is fixedly connected to the second nut block 216. The sliding engagement of the first sliding member 218 and the second sliding member 219 with the first guide member 217 provides guidance for the displacement of the first supporting member 211 and the second supporting member 212 along the Y-axis, preventing uneven force during movement and ensuring stable and reliable positioning of the paper tray 100.

[0049] In some optional embodiments, the clamping assembly 22 includes a second driving member and a clamping member 221. The second driving member includes a second handwheel 222, a second lead screw 223, and a third nut block 224. The second lead screw 223 extends along the Z-axis direction. The second handwheel 222 is coaxially connected to the second lead screw 223. The third nut block 224 is screwed to the second lead screw 223. The clamping member 221 is fixedly connected to the third nut block 224 for clamping the paper tray 100. By rotating the handwheel, the clamping force of the clamping member 221 on the paper tray 100 can be flexibly adjusted. On the one hand, it prevents the paper tray 100 from loosening due to insufficient clamping force, eliminating safety hazards during the cutting process and facilitating cutting. On the other hand, it prevents the paper tray 100 from deforming due to excessive clamping force, affecting the test results, and also prevents the paper tray 100 from becoming too dense under pressure, which would increase the difficulty of cutting.

[0050] Furthermore, the clamping assembly 22 also includes a second guide member 225 and a third sliding member 226 that are slidably engaged. The second guide member 225 is arranged parallel to the second lead screw 223, and the third sliding member 226 is fixedly connected to the third nut block 224. The sliding engagement of the second guide member 225 and the third sliding member 226 provides guidance for the lifting and lowering of the clamping member 221, avoiding swaying and jamming problems caused by uneven force during the lifting and lowering of the clamping member 221, ensuring the smoothness of movement, and improving the positional accuracy of the lifting and lowering of the clamping member 221; at the same time, it can distribute the radial load borne by the lead screw, reduce the frictional wear between the lead screw and the nut block, and extend the service life of the assembly.

[0051] In some optional embodiments, the surfaces of the first support member 211, the second support member 212 and the clamping member 221 are all provided with anti-slip and wear-resistant layers, which can improve the friction between the three and the paper tray 100, enhance the limiting stability of the paper tray 100 and avoid damage to the surface of the paper roll.

[0052] Optionally, the anti-slip and wear-resistant layer may include, but is not limited to, a rubber material or a metal layer that has undergone surface hardening treatment.

[0053] like Figure 1 and Figure 3 As shown, in some optional embodiments, the thickness adjustment assembly 33 includes a third handwheel 331, a third lead screw 332, and a fourth nut block 333. The third lead screw 332 extends along the Z-axis direction. The third handwheel 331 is coaxially connected to the third lead screw 332. The fourth nut block 333 is screwed into the third lead screw 332. The cutting blade 32 is fixedly connected to the fourth nut block 333. By rotating the third handwheel 331, the cutting thickness of the cutting blade 32 can be flexibly adjusted to meet the sampling requirements of different types of paper trays 100. Furthermore, by utilizing the self-locking property and precision transmission characteristics of the screw drive, the rotational motion of the handwheel can be converted into the linear lifting and lowering of the cutting blade 32, achieving micro-precise adjustment of the cutting thickness, reducing sample thickness deviation, and lowering material waste.

[0054] In some optional embodiments, the thickness adjustment assembly 33 further includes a third guide 334 and a fourth slider 335 that are slidably engaged. The third guide 334 is arranged parallel to the third lead screw 332, and the fourth slider 335 is fixedly connected to the fourth nut block 333. The sliding engagement of the third guide 334 and the fourth slider 335 can provide guidance for the movement of the cutting blade 32 along the Z-axis, making the lifting and lowering of the cutting blade 32 more stable, avoiding the deviation in the feed thickness caused by offset, improving the adjustment accuracy of the feed thickness, and reducing the sample thickness deviation.

[0055] In some optional embodiments, the thickness adjustment assembly 33 further includes at least two first limiting members 336 connected to the mounting bracket 31, one of which is disposed above the fourth nut block 333 to abut against the upper end of the fourth nut block 333, and the other is disposed below the fourth nut block 333 to abut against the lower end of the fourth nut block 333, thereby limiting the vertical travel range of the fourth nut block 333 along the Z-axis, thereby limiting the cutting thickness adjustment range of the cutting blade 32 and avoiding equipment damage or personal safety issues caused by cutting beyond the range.

[0056] In some optional embodiments, the thickness adjustment component 33 further includes an coded dial 337 connected to the third handwheel 331 and the third lead screw 332. The coded dial 337 can calculate the moving distance of the fourth nut block 333, i.e., the feed thickness, based on the number of rotations of the third lead screw 332, and can display the feed thickness for precise adjustment of the cutting thickness. Furthermore, the coded dial 337 can be set with fixed settings. For example, the coded dial 337 can be set with rapid feed thicknesses of 10mm and 30mm, allowing the operator to quickly select the setting, adapting to most sampling scenarios and further improving sampling efficiency. The specific structure of the coded dial 337 is prior art and will not be described in detail here.

[0057] In some optional embodiments, the feed assembly 34 includes a fourth handwheel 341, a fourth lead screw 342, and a fifth nut block 343. The fourth lead screw 342 extends along the X-axis, the fourth handwheel 341 is coaxially connected to the fourth lead screw 342, the fifth nut block 343 is screwed to the fourth lead screw 342, and the mounting bracket 31 is fixedly connected to the fifth nut block 343. By utilizing the screwed engagement of the fourth lead screw 342 and the fifth nut block 343, the rotational motion applied to the handwheel by the operator is converted into a linear feed motion of the cutting blade 32 along the X-axis. This reduces the force required for cutting. Compared to manual operation by directly pushing the cutting blade 32, sufficient cutting load can be obtained without applying a large pushing force, reducing the required operating force for cutting from over 80N to below 35N. The operator can easily complete the cutting with one hand, significantly reducing the operator's labor intensity. Meanwhile, the uniform force characteristics of the screw drive can ensure that the cutting edge is subjected to uniform force during the cutting process, avoiding jamming or cutting deviation, ensuring a smooth and controllable cutting process, and further improving the stability and reliability of the cutting operation.

[0058] Furthermore, the feed assembly 34 also includes a fourth guide and a fifth sliding member that are slidably engaged. The fourth guide is arranged parallel to the fourth lead screw 342, and the fifth sliding member is fixedly connected to the fifth nut block 343. The sliding engagement of the fourth guide and the fifth sliding member provides guidance for the movement of the cutting blade 32 along the X-axis, making the cutting blade 32 cut more smoothly, avoiding deviation that could cause positional deviation of the cutting blade 32, reducing cutting resistance, and ensuring a smooth sample cut.

[0059] In some optional embodiments, the feed assembly 34 further includes at least two second limiting members 344, which are connected to the mounting bracket 31 and respectively disposed on both sides of the fifth nut block 343 along the X-axis direction. They are used to abut against the corresponding ends of the fifth nut block 343 to limit the travel range of the fifth nut block 343 along the X-axis direction, thereby limiting the feed depth of the cutting blade 32 and avoiding equipment damage or personal safety issues caused by excessive cutting depth.

[0060] In some optional embodiments, the cutting blade 32 includes a blade holder 321 and at least two cutting heads 322. The at least two cutting heads 322 are spaced apart from each other along the Y-axis and connected to the blade holder 321, enabling a single cutting motion along the X-axis to complete the integrated cutting of a sample of a specified width without the need for multiple positioning and cutting steps, further simplifying the workflow and improving sampling efficiency. Furthermore, the fixed spacing between the cutting heads 322 ensures the consistency of the width of the cut sample, avoiding dimensional deviations caused by multiple cutting steps.

[0061] In some optional embodiments, the cutting edge angle of the blade 322 is 25°~30°, which can ensure that the cutting edge has sufficient cutting sharpness to easily cut into various types of paper and reduce cutting resistance, while avoiding the problem of easy breakage of the cutting edge caused by too small an angle, thus improving the durability of the blade 322; at the same time, it is adapted to the precise sampling requirements of the paper tray 100, ensuring that the cutting edge is flat and burr-free, and ensuring sample quality.

[0062] In some optional embodiments, the cutter head 322 is made of tungsten steel. Tungsten steel has high hardness and strong wear resistance, which is suitable for the high-frequency cutting requirements in the paper tray 100 cutting scenario. It can effectively extend the service life of the cutter head 322 and reduce the frequency of edge wear and dulling.

[0063] In some optional embodiments, the cutting edge surface is coated with a Teflon anti-stick coating.
