Description

Technical Field

[0001] This invention belongs to the technical field of tobacco processing equipment, specifically relating to a slicing machine with a bottom-turning feeding device and its operating method. Background Technology

[0002] In the tobacco processing production line, the slicing process is a core and critical process in the early stage of tobacco processing. It is mainly used to cut the whole stack of tobacco leaves after removing the outer packaging into standard tobacco blocks according to the required thickness specified in the production process. The cut tobacco blocks need to be arranged tightly and flat on the belt conveyor to ensure a stable and uniform material flow in subsequent processes, providing a qualified material basis for subsequent processing processes such as leaf moistening, shredding, and drying.

[0003] The existing conventional slicing equipment operates as follows: tobacco blocks are continuously fed horizontally via a belt conveyor. After being conveyed to the designated position of the cutting head, the cylinder drives the cutter to perform vertical slicing perpendicular to the tobacco block, achieving continuous and stable cutting of the tobacco sheets. After cutting, the tobacco sheets are tilted by the cooperation of a material unloading device and a baffle plate to complete the unloading operation, allowing the tobacco sheets to fall vertically to the discharge port, and then conveyed by a belt conveyor to the next processing step.

[0004] However, the existing technical solutions have obvious drawbacks in actual production applications: the bottom surface of the existing unloading device is a fixed plane structure, and during the unloading process, a large sliding friction force is generated between the bottom surface of the unloading device and the bottom surface of the tobacco sheet. Since the tobacco sheet is formed by stacking and pressing tobacco leaves, the binding force between the tobacco leaves inside is relatively weak. When the sliding friction force between the unloading device and the bottom surface of the tobacco sheet is greater than the interaction force of the internal structure of the tobacco sheet, the bottom layer of tobacco leaves will be directly pulled and peeled off during the unloading process to form independent small tobacco sheets.

[0005] During their descent, the detached tobacco flakes become misaligned and separate from the main tobacco sheet. This results in uneven height distribution of the tobacco sheets after cutting, leading to a misaligned arrangement. Furthermore, the pulling force of friction causes the main tobacco sheet to tilt and shift, resulting in uneven and loose horizontal distribution. These problems ultimately lead to large fluctuations in the flow rate and poor consistency of the tobacco material entering subsequent processes. This severely impacts the processing stability of the entire tobacco processing flow, reduces the quality of the finished tobacco product, and easily generates broken and waste tobacco flakes, causing raw material waste and hindering continuous and standardized operation of the production line.

[0006] In summary, existing slicing and unloading devices suffer from high friction due to their planar load-bearing structure, which easily leads to a series of problems such as tearing of tobacco sheets, resulting in broken tobacco, disordered tobacco sheet arrangement, and unstable feed flow. The existing equipment structure cannot simultaneously meet the multiple process requirements of complete tobacco sheet unloading, orderly arrangement, and uniform feeding. Therefore, there is an urgent need in this field for a slicing and unloading device that can reduce the sliding friction at the bottom of the tobacco sheets during the unloading stage, avoid the problem of tearing and peeling between tobacco leaf layers, ensure the integrity of the cut tobacco sheets, ensure a flat and uniform discharge arrangement, stabilize the feed flow at the rear end, reduce the generation of broken tobacco waste, and be suitable for standardized mass production of tobacco.

[0007] To address the above problems, this invention is proposed. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a flip-type slicing machine unloading device. This device effectively solves the technical problems of excessive friction in existing unloading devices, leading to tobacco sheet detachment, uneven distribution, and large fluctuations in material flow. It improves the consistency of the material state after tobacco sheet cutting and enhances production stability. This invention eliminates friction between the unloading device and the tobacco sheet, preventing damage to the tobacco sheet and ensuring uniform distribution of the cut tobacco sheets, thus providing a more stable supply for subsequent processing steps.

[0009] This invention discloses a slicing machine with a bottom-flipping material-discharging device and its operating method. The slicing machine includes a slicing machine body, a conveyor belt 1, a cutting blade assembly 2, a baffle plate 3, a bottom-flipping material-discharging device 4, and a receiving guide plate 5. The bottom-flipping material-discharging device 4 is a hollow frame, including a discharging device body 41, a flipping material-receiving bottom surface 42, and a flipping drive cylinder 44. The discharging device body 41 and the flipping material-receiving bottom surface 42 enclose a central hollow portion 43. The flipping material-receiving bottom surface 42 can be independently flipped relative to the discharging device body 41. This invention abandons the operation mode of the entire discharging device flipping and pushing against the tobacco leaves, and eliminates the relative sliding friction between the discharging structure and the bottom surface of the tobacco leaves. Relying on the independent flipping of the discharging bottom surface and the stationary operation mode of the device body, the tobacco leaves are not pulled or scraped by the bottom surface throughout the process, thus avoiding the peeling and tearing of the bottom tobacco leaves from the root and eliminating the generation of broken tobacco leaves and waste tobacco leaves. This invention can reduce friction between the feeding device and the tobacco sheets, reduce damage to the tobacco sheets, and make the cut tobacco sheets evenly distributed, providing a more stable supply of materials for subsequent processing.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] The first aspect of the present invention provides a slicer with a bottom-flipping material pouring device, the slicer comprising a slicer body, a conveyor belt 1, a cutting blade assembly 2, a baffle plate 3, a bottom-flipping material pouring device 4, and a receiving guide plate 5;

[0012] The bottom-flipping material pouring device 4 is a hollow frame. The bottom-flipping material pouring device 4 includes a material pouring device body 41, a flipping material receiving bottom surface 42, and a flipping drive cylinder 44. The material pouring device body 41 and the flipping material receiving bottom surface 42 enclose a central hollow part 43.

[0013] The flip-up material-bearing bottom surface 42 can be flipped independently relative to the main body 41 of the pouring device.

[0014] Preferably, the conveyor belt 1 is located upstream of the cutter assembly 2, and the cigarette pack 6 to be cut is conveyed downstream via the conveyor belt 1 until it reaches the designated cutting station of the cutter assembly 2;

[0015] The cutter of the cutter assembly 2 moves downward under the drive of the cutter cylinder to complete the vertical cutting operation on the cigarette pack 6 to be cut in the horizontal state at the work station, and obtain the cut cigarette pack 7.

[0016] The bottom-flipping material pouring device 4 is installed and fixed on the discharge side of the cutter assembly 2 of the slicer. The flipping material-bearing bottom surface 42 is independently flipped relative to the main body 41 of the material pouring device under the drive of the flipping drive cylinder 44.

[0017] The baffle plate 3 is located on the discharge side of the cutter assembly 2, and the baffle plate 3 is located at the downstream end of the hollow part 43;

[0018] The receiving guide plate 5 is located below the flipping material receiving bottom surface 42.

[0019] Preferably, the slicer has two states: non-discharging operation and discharging operation.

[0020] In the non-pouring operation state, the main body 41 of the pouring device is vertical and the bottom surface 42 of the flipping material receiving device is horizontal. The cut cigarette pack 7 is located in the hollow part 43. The baffle plate 3 fits and limits the downstream side of the cut cigarette pack 7 to limit the horizontal displacement of the cut cigarette pack 7 during the non-pouring operation.

[0021] In the unloading operation state, the main body 41 of the unloading device is still in a vertical state. The flipping material receiving bottom surface 42 is flipped 90° away from the flipped and cut tobacco pack 7 under the drive of the flipping drive cylinder 44. The flipping material receiving bottom surface 42 is in a vertical state so as to expose the drop port 8. The cut tobacco pack 7 falls down along the receiving guide plate 5 through the drop port 8.

[0022] Preferably, after one material unloading operation is completed, the bottom-flipping unloading device 4 returns to the non-unloading operation state, waiting for the next material unloading operation.

[0023] Preferably, the flipping material-bearing bottom surface 42 is hinged to the bottom of the main body 41 of the pouring device, and the top surface of the flipping material-bearing bottom surface 42 is used to support the tobacco sheets after cutting; the flipping drive cylinder 44 is hinged to the side wall of the main body 41 of the pouring device, and the piston rod end of the flipping drive cylinder 44 is hinged to the bottom surface of the flipping material-bearing bottom surface 42 for transmission, and is used to drive the flipping material-bearing bottom surface 42 to flip independently around the hinge point.

[0024] Preferably, the flip-over material-bearing bottom surface 42 is a flat, rigid plate structure.

[0025] Preferably, the tilting drive cylinder 44 is equipped with an electronically controlled speed regulating valve to adjust the tilting angular velocity of the tilting material support bottom surface 42, adapting to the unloading speed of tobacco sheets of different thicknesses.

[0026] A second aspect of the present invention provides a method for operating a slicing machine with a bottom-flipping feeding device, applicable to the slicing machine with a bottom-flipping feeding device described in the first aspect of the present invention, comprising the following operating steps:

[0027] S1. Feeding and conveying: The cigarette pack 6 to be cut is conveyed downstream at a uniform speed through the conveyor belt 1 until the cigarette pack 6 to be cut accurately reaches the preset cutting position of the cutting blade assembly 2, keeping the cigarette pack 6 to be cut in a horizontal position.

[0028] S2, Vertical cutting: The cutter of the cutter assembly 2 moves vertically downward under the drive of the cutter cylinder to complete the vertical cutting operation on the cigarette pack 6 to be cut in the horizontal state at the cutting station, and obtain the cut cigarette pack 7.

[0029] S3, Station Limiting and Bearing: After cutting, the cut cigarette pack 7 falls into the hollow part 43 of the bottom flip-type material pouring device 4, and is supported by the flip-type material-bearing bottom surface 42 of the bottom flip-type material pouring device 4; at this time, the slicer is in a non-pouring operation state, the main body 41 of the material pouring device remains vertical, the flip-type material-bearing bottom surface 42 remains horizontal, and at the same time, the baffle plate 3 adheres to and presses against the downstream side of the cut cigarette pack 7, limiting the horizontal displacement of the cut cigarette pack 7 and locking the vertical falling posture of the cut cigarette pack 7;

[0030] S4. Material Discharge: Initiate the material discharge operation by activating the tilting drive cylinder 44. The cylinder piston rod retracts, causing the tilting support bottom surface 42 to tilt 90° away from the tilted and cut cigarette pack 7 (i.e., tilting downwards). The tilting support bottom surface 42 is now vertical, exposing the discharge port 8. The cut cigarette pack 7, under its own weight, falls through the discharge port 8 to the receiving guide plate 5 below, completing the material discharge along the receiving guide plate 5. The fallen material is then conveyed to the next processing step via another conveyor belt mechanism.

[0031] Preferably, the operation method further includes step S5, resetting standby: after a single material pouring operation is completed, the piston rod of the flipping drive cylinder 44 extends, driving the flipping material receiving bottom surface 42 to flip upward and reset to the horizontal material receiving position, the slicer returns to the non-material pouring operation state, and steps S1-S5 are executed cyclically to complete the batch cigarette pack slice pouring operation.

[0032] Preferably, in step S4, the flipping angle of the bottom surface 42 is 90°, so that the tobacco sheets fall freely without obstruction and the falling point is uniform.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. This invention abandons the operation mode of the entire material pouring device flipping and pushing the tobacco sheets, and eliminates the relative sliding friction between the material pouring structure and the bottom surface of the tobacco sheets. Relying on the operation mode of the bottom surface of the material pouring independently flipping and the main body of the device remaining stationary, the tobacco sheets are not pulled or scraped by the bottom surface throughout the process, thus avoiding the peeling and tearing of the bottom tobacco leaves from the source, eliminating the generation of broken tobacco sheets and waste tobacco sheets, reducing tobacco raw material loss, and lowering the cost of production waste disposal.

[0035] 2. After being cut, the standard tobacco sheets fall vertically and freely under their own weight, without lateral friction or lateral thrust. The tobacco sheets fall vertically and land at a uniform point. After being discharged, they are arranged tightly, flat, and aligned in the same direction on the conveyor belt, without any unevenness, tilting, or looseness. The tobacco sheet packing density and arrangement specifications are uniform.

[0036] 3. This invention can ensure a constant material flow rate and strong consistency of material state in the subsequent processes of leaf moistening, shredding, and drying, avoid process parameter adaptation deviations caused by fluctuations in incoming materials, optimize the processing stability of the entire tobacco-making process, improve core quality indicators such as the uniformity and sensory quality of finished tobacco, and adapt to continuous and standardized mass production operations on the production line.

[0037] 4. The overall transformation can be adapted by adding the existing slicing equipment frame, cutter and conveying mechanism. Only the bottom driving cylinder and the flipping material receiving bottom surface 2 need to be added, and the amount of transformation work is small. The cylinder driven flipping action has fast response and high action accuracy. The equipment is not prone to material jamming or blockage. The failure rate is low and it is suitable for the high-load continuous production conditions of tobacco processing workshop. Attached Figure Description

[0061] In the non-pouring operation state, the main body 41 of the pouring device is vertical and the bottom surface 42 of the flipping material receiving device is horizontal. The cut cigarette pack 7 is located in the hollow part 43. The baffle plate 3 fits and limits the downstream side of the cut cigarette pack 7 to limit the horizontal displacement of the cut cigarette pack 7 during the non-pouring operation.

[0062] In the unloading operation state, the main body 41 of the unloading device is still in a vertical state. The flipping material receiving bottom surface 42 is flipped 90° away from the flipped and cut tobacco pack 7 under the drive of the flipping drive cylinder 44. The flipping material receiving bottom surface 42 is in a vertical state so as to expose the drop port 8. The cut tobacco pack 7 falls down along the receiving guide plate 5 through the drop port 8.

[0063] After one material unloading operation is completed, the bottom-flipping unloading device 4 returns to the non-unloading operation state, waiting for the next unloading operation.

[0064] The flip-up material-bearing bottom surface 42 is hinged to the bottom of the main body 41 of the pouring device, and the top surface of the flip-up material-bearing bottom surface 42 is used to support the cut tobacco sheets; the flip-up drive cylinder 44 is hinged to the side wall of the main body 41 of the pouring device, and the piston rod end of the flip-up drive cylinder 44 is hinged to the bottom surface of the flip-up material-bearing bottom surface 42 for transmission, and is used to drive the flip-up material-bearing bottom surface 42 to flip independently around the hinge point.

[0065] The flip-over material-bearing bottom surface 42 is a flat, rigid plate structure.

[0066] The tilting drive cylinder 44 is equipped with an electronically controlled speed regulating valve to adjust the tilting angular velocity of the tilting material support bottom surface 42, adapting to the unloading speed of tobacco sheets of different thicknesses.

[0067] The operating method of the slicer with a bottom-flipping material-discharging device described in this embodiment includes the following operating steps:

[0068] S1. Feeding and conveying: The cigarette pack 6 to be cut is conveyed downstream at a uniform speed through the conveyor belt 1 until the cigarette pack 6 to be cut accurately reaches the preset cutting position of the cutting blade assembly 2, keeping the cigarette pack 6 to be cut in a horizontal position.
