Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a cigarette pack slicing device. Background Technology

[0002] In the cigarette manufacturing process, the tobacco processing stage is crucial. The tobacco processing stage involves a series of steps, including cutting the tobacco leaves from the parchment, slicing, moistening and adding flavorings, leaf aging, shredding, leaf expansion, leaf drying, blending, and flavoring, to produce finished tobacco that meets specific technological standards and is ready for rolling. Within this series of processing steps, the slicing stage involves using slicing equipment to cut the unpacked cigarette parchment into tobacco blocks or sheets according to process requirements and set parameters.

[0003] The relevant slicing equipment detects the length of the cigarette pack through a light curtain, calculates the thickness of each cigarette pack based on the required number of cigarette packs to be sliced, and pushes the cigarette pack forward to the cutting blade through the push plate inside the slicer according to the calculated thickness value, thus completing the slicing.

[0004] However, since the cutter itself has a certain thickness, during the cigarette pack slicing process, the cutter will compress the cigarette pack due to its own thickness, which will have a certain impact on the thickness of the cigarette pack slices. Utility Model Content

The distance between the first preset position A and the slicing mechanism in the first direction is the cutting thickness of the cigarette pack; while the slicing mechanism moves down to cut the cigarette pack, the smoke-blocking component of the retracting smoke-blocking mechanism retracts along the first direction to a second preset position B. The distance K between the first preset position A and the second preset position B is a buffer zone for the cigarette pack to be cut and squeezed; while the slicing mechanism rises after completing the cutting, the smoke-blocking component of the retracting smoke-blocking mechanism continues to retract along the first direction to a third preset position C. The distance Y between the first preset position B and the third preset position C is a clearance zone for the cigarette pieces to fall out. During the process of the slicing mechanism cutting the tobacco pack, the smoke-blocking component of the retracting smoke-blocking mechanism can retract from the first preset position A to the second preset position B along the first direction. This is used to buffer the squeezing deformation caused when the tobacco pack is cut, eliminate the influence of the thickness of the slicing mechanism itself, not only ensure the uniform thickness of the tobacco slices, but also help the subsequent electronic scale to weigh the material evenly and stably, and achieve precise processing of subsequent processes such as loosening and moistening the leaves and adding the leaves.

[0045] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0046] In the complex process of cigarette manufacturing, the tobacco processing stage undoubtedly occupies a core and crucial position, serving as a key hub in the entire cigarette manufacturing process. The tobacco processing stage plays an extremely important role in the entire cigarette production chain. Its main task is to transform the tobacco leaves, after being threshed and re-dried, into finished tobacco shreds that meet specific technological standards and can be directly used for cigarette making through a series of rigorous and meticulous processing steps.

[0047] Specifically, the tobacco processing stage encompasses a series of interconnected yet distinct steps. First is the pack-cutting and box-removal process, which requires precisely cutting the bindings on the packs and removing them from the box, preparing them for subsequent processing. Next is the slicing process, where specialized slicing equipment cuts the unpacked packs into uniformly sized pieces or flakes according to pre-set process requirements and parameters, facilitating better processing later. The leaf-conditioning and additive process involves evenly adding various necessary additives to the sliced ​​tobacco flakes, improving the aroma, taste, and other quality characteristics of the tobacco leaves. The leaf aging process, through specific environmental conditions and time control, induces a series of beneficial changes in the chemical components of the tobacco leaves, further enhancing their quality and flavor. The leaf-shredding process further cuts the aging leaves into thin shreds, laying the foundation for subsequent expansion and drying processes. The leaf shredding process increases the volume of the shreds, improving their physical properties and enhancing the tobacco's filling capacity and combustion performance. The tobacco leaf drying process involves controlling parameters such as temperature and humidity to adjust the moisture content of the tobacco leaves to a suitable range, ensuring stable quality. The blending process involves mixing different types and qualities of tobacco leaves in a specific ratio to achieve the desired flavor and quality. Finally, the flavoring process involves adding appropriate amounts of flavorings to the blended tobacco leaves, giving them a unique aroma and flavor that better suits consumer tastes.

[0048] Among the many processing steps in the tobacco manufacturing process, the slicing step is undeniably crucial. The specific operation involves placing the unpacked cigarette packs from their cartons into a specialized slicing machine. This machine is equipped with an advanced light curtain detection system that accurately detects the length of the cigarette packs. Based on the pre-set number of cigarette packs to be sliced, the machine uses an internal calculation program to precisely calculate the thickness of each slice. Subsequently, the push plate inside the slicing machine, according to the calculated thickness value, smoothly and precisely pushes the cigarette packs forward according to a predetermined action sequence until the packs reach the cutting blade, completing the slicing operation.

[0049] However, several factors can affect the thickness of cigarette pack slices during the actual slicing process. One significant factor is the thickness of the cutting blade itself. During cigarette pack slicing, the blade's thickness exerts a squeezing effect on the pack as it cuts into it. This squeezing can cause a deviation between the actual slice thickness and the pre-set thickness, affecting the quality and consistency of the slices. Additionally, the pusher plate may also experience movement errors as it propels the pack forward for slicing. These errors can be caused by various factors, such as wear on mechanical parts, precision issues in the control system, or interference from the external environment. If the pusher plate malfunctions, the cigarette pack will not reach the cutting blade accurately, resulting in slices that do not meet requirements and negatively impacting subsequent processing steps and the quality of the final product.

[0050] To ensure uniform tobacco sheet thickness, this embodiment provides a tobacco pack slicing device, which is described below in conjunction with... Figures 1 to 7 The specific content of this embodiment will be described in detail. It should be noted that the first direction mentioned in this embodiment is... Figure 1 The X direction in this embodiment refers to the second direction or vertical direction. Figure 1 in the Y direction.

[0051] This utility model provides a tobacco pack slicing device, which includes a feeding and conveying mechanism 1, a slicing mechanism 2, and a retraction smoke-blocking mechanism 3. The feeding and conveying mechanism 1 has a loading station and a cutting station at its two ends, respectively, and is used to convey tobacco packs 100 from the loading station to the cutting station. The slicing mechanism 2 is located above the cutting station and is used to cut the tobacco packs 100. The retraction smoke-blocking mechanism 3 is located on the discharge side of the cutting station and includes a guide rail 31 and a smoke-blocking component. The tobacco pack 100 stops at the smoke-blocking component, which is mounted on the guide rail 31 and can move in a first direction away from the feeding and conveying mechanism 1. The guide rail 31 provides a stable track for the movement of the smoke-blocking component, ensuring the smoothness and accuracy of its movement. The smoke-blocking component serves to block and position the tobacco pack 100. During the cutting process, it can precisely control the cutting position and thickness of the tobacco pack 100 according to preset programs and parameters.

[0052] In short, in the actual operation of the cigarette pack slicing equipment provided by this utility model, firstly, the cigarette pack 100 to be cut is smoothly transported from the loading station to the cutting station through the feeding conveying mechanism 1. At this time, the smoke baffle 37 of the retracting smoke baffle mechanism 3 quickly moves to the first preset position A, and the cigarette pack 100 stops precisely at the smoke baffle component of the retracting smoke baffle mechanism 3 after being transported to the position. The distance between the first preset position A and the slicing mechanism 2 in the first direction is precisely calculated and set (for example, the total thickness of the cigarette pack 100 is obtained by measuring instruments, and the thickness of a single tobacco slice 200 is determined according to the number of slices), which is exactly the cutting thickness of the cigarette pack 100. This setting ensures the accuracy and consistency of the cutting. When the slicing mechanism 2 begins to move down to cut the cigarette pack 100, the smoke baffle component of the retracting smoke baffle mechanism 3 is not stationary, but will retreat along the first direction to the second preset position B. The distance K between the first preset position A and the second preset position B is set as the buffer zone where the cigarette pack 100 is cut and squeezed. During the slicing process, because the cutter 21 itself has a certain thickness, when the cutter 21 cuts into the tobacco pack 100, it will exert a squeezing effect on the tobacco pack 100, causing the tobacco pack 100 to deform to a certain extent. The retracting action of the smoke-blocking component of the retracting smoke-blocking mechanism 3 during this process provides a buffer space for the squeezing deformation of the tobacco pack 100, effectively eliminating the influence of the slicing mechanism 2's own blade thickness on the cutting thickness of the tobacco pack 100. This is like providing an elastic buffer zone for the tobacco pack 100 during the cutting process, allowing the tobacco pack 100 to maintain a relatively stable shape when being cut, thereby ensuring that the thickness of the cut tobacco slices 200 is uniform. While the slicing mechanism 2 rises after completing the cut, the smoke-blocking component of the retracting smoke-blocking mechanism 3 continues to retract along the first direction to the third preset position C. The distance Y between the first preset position B and the third preset position C is set as the avoidance zone for the tobacco slices 200 to fall out. This design allows the cut smoke sheet 200 to fall smoothly from the equipment, avoiding the accumulation or jamming of the smoke sheet 200 due to obstruction by the smoke baffle component, thus ensuring the continuous and stable operation of the equipment.

[0053] The precise backward movement of the smoke-blocking component of the retracting smoke-blocking mechanism 3 during the cutting process provides a buffer space for the compression deformation generated when the tobacco pack 100 is cut, effectively eliminating the influence of the blade thickness of the slicing mechanism 2 on the cutting thickness of the tobacco pack 100. In traditional tobacco pack slicing equipment, due to the unavoidable thickness of the cutter 21, the tobacco pack 100 is compressed during the cutting process, resulting in uneven thickness of the cut tobacco slices 200, with some areas being thicker and others thinner. However, this equipment, through this ingenious design, allows the tobacco pack 100 to maintain a relatively stable shape during the cutting process, thereby ensuring that the cut tobacco slices 200 have a uniform thickness.

[0054] Furthermore, the retractable smoke-blocking mechanism 3 also includes a motor with an encoder. The motor is connected to the smoke-blocking component via a transmission device (common transmission methods may include gear drive, chain drive, or synchronous belt drive. Taking gear drive as an example, a small gear is mounted on the motor's output shaft, and a rack meshes with it on the smoke-blocking component. Through precise transmission between the gear and rack, the rotational motion of the motor is converted into linear movement of the smoke-blocking component along the first direction). The motor drives the smoke-blocking component to move along the first direction. Adjusting the movement distance of the smoke-blocking component via the motor (also known as a servo motor) helps improve the movement accuracy of the smoke-blocking component, ensuring the uniform thickness of the tobacco sheet 200. In actual cigarette production, different cigarette pack 100 specifications and process requirements may require different adjustments to the movement distance of the smoke-blocking component. The motor with the encoder can easily handle these diverse needs. By pre-setting different programs and parameters in the control system, the motor can quickly and accurately adjust the movement distance of the smoke-blocking component according to different process requirements. For example, for a thicker cigarette pack 100, the smoke-blocking component may need to be moved to a farther position to ensure cutting accuracy; while for a thinner cigarette pack 100, the smoke-blocking component can be moved to a closer position. This flexible adjustment capability allows the equipment to adapt to various production scenarios, improving its versatility and production efficiency.

[0055] Furthermore, at least two guide rails 31 are spaced apart and extend along a first direction. This spacing ensures sufficient space between the guide rails 31 for easy installation of the smoke-blocking assembly. The design of extending along the first direction allows the smoke-blocking assembly to move precisely along a specific straight line, meeting the precise requirements for smoke-blocking position during the cutting of the tobacco pack 100. The smoke-blocking assembly includes a moving rod 32, a smoke-blocking frame 33, and a first driving cylinder 34. The two ends of the moving rod 32 are slidably connected to the two guide rails 31, and a first cantilever portion 321 is provided on the moving rod 32. The upper frame of the smoke-blocking frame 33 is rotatably connected to the moving rod 32. The cylinder body of the first driving cylinder 34 is hinged to the first cantilever portion 321, and the piston rod of the first driving cylinder 34 is hinged to the smoke-blocking frame 33. The piston rod of the first driving cylinder 34 can keep the smoke-blocking frame 33 in a vertical state or flip it to an inclined state. When the tobacco pack 100 is cut, the piston rod of the first driving cylinder 34 extends. At this time, the piston rod applies a downward thrust to the smoke-blocking frame 33, keeping it vertical. The vertical smoke-blocking frame 33 effectively blocks the tobacco sheet 200, providing a stable boundary for the cutting process. Technically, this vertical position ensures that the tobacco sheet 200 is cut according to the predetermined direction and position during the cutting of the cigarette pack 100, avoiding cutting deviations caused by improper positioning of the smoke-blocking frame 33. For example, during high-speed cutting, if the smoke-blocking frame 33 cannot remain vertical, the edges of the tobacco sheet 200 may become uneven, affecting the quality and appearance of the cigarettes. The vertical smoke-blocking frame 33 ensures cutting precision, ensuring that the size and shape of each tobacco sheet 200 meet process requirements, improving the consistency and stability of cigarette production. After the cigarette pack 100 is cut, the retracting smoke-blocking mechanism 3 not only retracts to the third preset position C, but the piston rod of the first drive cylinder 34 also shortens. Retracting to the third preset position C is to make room for subsequent processing of the tobacco sheet 200 and avoid interference with other components. The shortening of the piston rod of the first drive cylinder 34 keeps the smoke-blocking frame 33 in an inclined state. This inclined state has a significant technical effect, further ensuring the smooth detachment of the tobacco sheet 200. After the cigarette pack 100 is cut, the tobacco sheet 200 may adhere to the smoke-blocking frame 33 due to contact. If the smoke-blocking frame 33 remains vertical, the tobacco sheet 200 may be partially suspended on the smoke-blocking frame 33 due to gravity, resulting in unsmooth detachment. The inclined smoke-blocking frame 33 can utilize gravity to make it easier for the tobacco sheet 200 to slide down the inclined surface, avoiding structural interference between the tobacco sheet 200 and the smoke-blocking frame 33. For example, in some automated cigarette production lines, the inclined smoke-blocking frame 33 can ensure that the tobacco sheet 200 falls quickly and smoothly into the designated collection device, improving production efficiency and product quality.

[0056] Furthermore, a second cantilever portion 331 is provided on the smoke-blocking frame 33. The smoke-blocking assembly includes an L-shaped smoke hook plate 35 and a second driving cylinder 36. The L-shaped smoke hook plate 35 includes a first plate portion 351 and a second plate portion 352. The first plate portion 351 and the second plate portion 352 are vertically connected, and the first plate portion 351 is rotatably connected to the lower frame of the smoke-blocking frame 33. The cylinder body of the second driving cylinder 36 is hinged to the second cantilever portion 331, and the piston rod of the second driving cylinder 36 is hinged to the back of the first plate portion 351. The piston rod of the second driving cylinder 36 can keep the second plate portion 352 in a horizontal state or flip it to an inclined state. When the tobacco package 100 is cut, the piston rod of the second driving cylinder 36 extends. At this time, the piston rod of the second drive cylinder 36 applies a downward thrust to the back of the first plate 351. Due to the rotatable connection between the first plate 351 and the lower frame of the smoke-blocking frame 33, this force causes the L-shaped hook smoke plate 35 to rotate around the connection point, ultimately keeping the second plate 352 in a horizontal state. The second plate 352 is flush with the lower surface of the cigarette pack 100, a design with multiple technical benefits. First, the horizontal second plate 352 provides a stable support surface for the cigarette pack 100, ensuring that the cigarette pack 100 remains stable during cutting and avoiding inaccurate cutting due to shaking of the cigarette pack 100. For example, during high-speed cutting, even slight shaking of the cigarette pack 100 can lead to uneven cutting edges, affecting the quality of the cigarettes. The horizontal support of the second plate 352 effectively reduces this shaking and improves cutting accuracy. Second, the flushness of the second plate 352 with the lower surface of the cigarette pack 100 ensures that the bottom of the cut tobacco sheet 200 is flat, which is beneficial for subsequent processing of the tobacco sheet 200. After the tobacco pack 100 is cut, the retracting smoke-blocking mechanism 3 not only retracts to the third preset position C to make room for subsequent operations and avoid interference with other components, but also shortens the piston rod of the second drive cylinder 36. This shortening of the piston rod causes the first plate 351 to experience an upward pulling force, resulting in the L-shaped hook tobacco plate 35 flipping and keeping the second plate 352 in an inclined state. This inclined state has a significant technical effect, further ensuring the smooth detachment of the tobacco sheet 200. After the tobacco pack 100 is cut, the tobacco sheet 200 may adhere to the second plate 352 due to contact. If the second plate 352 remains horizontal, the tobacco sheet 200 may be partially suspended on it due to gravity, causing difficulty in detachment. The inclined second plate 352, however, utilizes gravity to make it easier for the tobacco sheet 200 to slide down the inclined surface. At the same time, the tilted position can also avoid structural interference between the tobacco sheet 200 and the second plate portion 352 of the L-shaped hook tobacco plate 35, ensuring the smooth progress of the entire tobacco sheet 200 processing process.

[0057] Furthermore, the smoke-blocking assembly includes a smoke-blocking plate 37, which is disposed on the side of the smoke-blocking frame 33 facing the feeding conveying mechanism 1, and the tobacco pack 100 stops against the smoke-blocking plate 37. By adding the smoke-blocking plate 37, the planar features of the smoke-blocking plate 37 can effectively block the tobacco pack 100. Compared with the tobacco pack 100 directly contacting the smoke-blocking frame 33, using the smoke-blocking plate 37 can increase the contact area with the tobacco pack 100. Furthermore, the slicing mechanism 2 includes a first lifting module and a cutter 21, which is disposed at the lifting end of the first lifting module. The lower end of the cutter 21 is the blade.

[0058] Furthermore, the upper side of the smoke baffle 37 is hinged to the smoke baffle frame 33, which gives the smoke baffle 37 a certain degree of freedom of movement. The smoke baffle assembly includes a start switch 38 and a trigger 39. The start switch 38 is located on the side of the smoke baffle frame 33 away from the feeding conveyor mechanism 1. The start switch 38 is electrically connected to the first lifting module. When the start switch 38 is triggered, it sends an electrical signal to the first lifting module, driving the cutter 21 to move down according to a preset program to complete the cutting action on the tobacco pack 100. The trigger 39 is located on the smoke baffle frame 33 and is telescopic. One end of the trigger 39 abuts against the smoke baffle 37, and the other end of the trigger 39 is used to contact the start switch 38. For example, the trigger 39 can be a telescopic column with a reset function. The telescopic column is usually equipped with a spring or other reset device inside, so that it always tends to move away from the start switch 38 and closer to the smoke baffle 37. One end of the telescopic column abuts against the first wall of the smoke baffle 37, and the other end is used to contact the start switch 38. This design allows the trigger 39 to sense changes in the state of the smoke baffle 37 in real time. When no smoke pack 100 is pressing against the smoke baffle 37, the telescopic column, under the action of the reset device, has one end in close contact with the first wall of the smoke baffle 37, while simultaneously creating a slight angle between the smoke baffle 37 and the smoke baffle frame 33. When the smoke pack 100 is conveyed to the cutting area along the feeding conveyor mechanism 1, the smoke pack 100 comes into contact with the second wall of the smoke baffle 37 (the first and second walls are located on opposite sides of the smoke baffle 37, respectively). As the smoke pack 100 continues to advance, it applies pressure to the smoke baffle 37 in the direction of the smoke baffle frame 33. This pressure overcomes the reset force of the telescopic column, causing the smoke baffle 37 to rotate around the hinge point, while simultaneously pressing against the telescopic column as it moves towards the start switch 38. The telescopic column gradually retracts under the push of the smoke baffle 37, and when its other end touches the start switch 38, the start switch 38 is triggered. Once the start switch 38 is triggered, it immediately sends an electrical signal to the first lifting module. Upon receiving the signal, the first lifting module quickly starts and drives the cutter 21 to move downwards at a preset speed and trajectory. The cutter 21 cuts into the cigarette pack 100 with precise force and angle, completing the cutting action. The entire process realizes an automated flow from the entry of the cigarette pack 100, triggering the start-up, to the cutting of the cutter 21, greatly improving production efficiency and cutting accuracy.

[0059] Furthermore, the cigarette pack slicing equipment also includes several pressing mechanisms 4. Each pressing mechanism 4 includes a second lifting module 41 and a pressure plate 42. The pressure plate 42 is located at the lifting end of the second lifting module 41, which drives the pressure plate 42 to move up and down in a second direction. The pressure plate 42 includes an integrally connected rectangular block and a triangular block. The end of the triangular block away from the rectangular block is the pressing surface, and the cross-sectional area of ​​the pressing surface is larger than that of the rectangular block. The triangular block increases the pressing area on the cigarette pack 100, ensuring that the cigarette pack 100 does not move during cutting. Exemplarily, the first lifting module and the second lifting module 41 can be cylinders, hydraulic cylinders, or electric actuators, etc., without further limitations.

[0060] Furthermore, the tobacco pack slicing equipment also includes a discharge conveying mechanism 5, which is located on the discharge side of the cutting station and below the retraction smoke-blocking mechanism 3. For example, both the feeding conveying mechanism 1 and the discharge conveying mechanism 5 are belt conveyors.
