Description

Technical Field

[0001] This invention belongs to the technical field of tobacco processing equipment, specifically relating to a slicing machine with a roller-type 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: the tobacco block is continuously fed horizontally by a belt conveyor. After being conveyed to the designated position of the cutter head, the cutter is driven by a cylinder to cut vertically perpendicular to the direction of the tobacco block, thus achieving continuous and stable cutting of the tobacco sheet. After the tobacco sheet is cut, it is flipped by the cooperation of the unloading device and the baffle assembly (3) to complete the unloading operation, so that the tobacco sheet falls vertically to the discharge port, and is 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] Furthermore, the existing slicing machine's baffle assembly is a fixed installation structure. During operation, the baffle plate remains stationary, and the material unloading action is completed solely by the rotation of the unloading device. The baffle plate cannot slide horizontally backward to avoid material impact during the unloading action. Relying solely on the unloading device to flip and maneuver the material feeding space on one side limits the opening of the material discharge port and results in a narrow lateral discharge space. When the cigarette packs are unloaded, they easily stick to the fixed baffle plate, causing them to accumulate and be squeezed. This not only slows down the unloading speed but also, under continuous unloading conditions, causes the cigarette packs to pile up and collide with each other, further exacerbating the problems of loosening and deformation of the cigarette packs. At the same time, the narrow material feeding space is prone to corner jamming and blockage, requiring manual cleaning at regular intervals, interrupting the continuous operation rhythm of the production line, further reducing the efficiency of the tobacco slicing process, and exacerbating the problem of uneven material distribution.

[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 slicing machine with a roller-type feeding device. This effectively solves the technical problems of excessive friction in existing feeding devices, which leads 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 reduces friction between the feeding device and the tobacco sheet, minimizing damage to the tobacco sheet and resulting in a more 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 roller-type feeding device and its operating method. The slicing machine includes a slicing machine body, a conveyor belt 1, a cutting blade assembly 2, a baffle assembly 3, a roller-type feeding device 4, and a receiving guide plate 5. The roller-type feeding device 4 is a hollow frame, including a feeding device body 41 and a supporting bottom surface 42, which together form a central hollow portion 43. The supporting bottom surface 42 is configured as a roller-type rolling bottom surface. This invention optimizes the traditional fixed planar feeding bottom surface into a roller-type rolling bottom surface, transforming sliding friction into rolling friction, significantly reducing the contact friction between the feeding device and the bottom surface of the tobacco sheet, ensuring that the friction force is always less than the bonding force of the internal structure of the tobacco sheet. At the same time, the bidirectional linkage feeding structure of rotating feeding device and horizontal sliding baffle plate completely solves the problem of bottom tobacco sheets being pulled off and producing small fragments during the feeding process. 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 present invention provides a slicer with a roller-type feeding device. The slicer includes a slicer body, a conveyor belt 1, a cutting blade assembly 2, a baffle assembly 3, a roller-type feeding device 4, and a receiving guide plate 5.

[0012] The roller-type material pouring device 4 is a hollow frame. The roller-type material pouring device 4 includes a material pouring device body 41 and a supporting bottom surface 42. The material pouring device body 41 and the supporting bottom surface 42 enclose a central hollow part 43.

[0013] The bearing bottom surface 42 is configured as a roller-type rolling bottom surface.

[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 roller-type material pouring device 4 is installed and fixed on the discharge side of the cutting blade assembly 2 of the slicer. The roller-type material pouring device 4 can rotate with the top of the material pouring device body 41 as the axis under the drive of the material pouring cylinder.

[0017] The material blocking assembly 3 is located on the downstream discharge side of the cutter assembly 2. The material blocking assembly 3 includes a material blocking plate 31 and a material blocking plate mounting rod 32. The material blocking plate 31 is mounted on the slicer via the material blocking plate mounting rod 32. The material blocking plate 31 can move horizontally along the material blocking plate mounting rod 32 under the drive of the material blocking plate cylinder.

[0018] The receiving guide plate 5 is located below the bearing 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 bearing bottom surface 42 is horizontal. The cut cigarette pack 7 is located in the hollow part 43. The baffle plate 31 is located upstream of the baffle plate mounting rod 32. The baffle plate 31 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, so as to ensure the vertical falling posture of the cut cigarette pack 7.

[0021] In the unloading operation, the roller-type unloading device 4, driven by the unloading cylinder, rotates about the top of the unloading device body 41 in a direction away from the cut tobacco pack 7. Simultaneously, the baffle plate 31, driven by the baffle plate cylinder, moves horizontally along the baffle plate mounting rod 32 in a direction away from the cut tobacco pack 7 to expose the discharge port 8. The cut tobacco pack 7 falls through the discharge port 8 along the receiving guide plate 5. During the unloading operation, the baffle assembly 3 abuts against one side of the tobacco sheet for limitation, and the roller-type bearing bottom surface 42 supports the bottom of the tobacco sheet, working in both directions to limit the tobacco sheet's flipping angle and precisely control the vertical drop of the tobacco sheet to the discharge port.

[0022] Preferably, after one material unloading operation is completed, the roller unloading device 4 and the baffle plate 31 return to the non-unloading operation state, waiting for the next material unloading operation.

[0023] Preferably, the roller-type material pouring device 4 can rotate 60° away from the cut tobacco pack 7 with the top of the material pouring device body 41 as the axis under the drive of the material pouring cylinder.

[0024] Preferably, the bottom surface 42 of the feeding device is uniformly fitted with multiple rows of freely rotatable roller groups 421, and each row of roller groups 421 includes multiple rollers 4211.

[0025] Preferably, the top ends of all the rollers 4211 are flush, together forming a rolling support surface for bearing and lifting the cut tobacco pack 7.

[0026] A second aspect of the present invention provides a method for operating a slicing machine with a roller-type feeding device, applicable to the slicing machine with a roller-type 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 roller-type pouring device 4 and is supported by the bearing bottom surface 42 of the roller-type pouring device 4; at this time, the slicer is in a non-pouring operation state, the main body 41 of the pouring device remains vertical, the bearing bottom surface 42 remains horizontal, and at the same time, the baffle plate 31 moves to the upstream position of the baffle plate mounting rod 32 under the drive of the baffle plate cylinder, the baffle plate 31 fits against the downstream side of the cut cigarette pack 7, limits the horizontal displacement of the cut cigarette pack 7, and locks the vertical falling posture of the cut cigarette pack 7;

[0030] S4. Linked Material Discharge: The material discharge operation is initiated. The material discharge cylinder drives the roller-type material discharge device 4 to rotate about the top of the main body 41 of the material discharge device, moving away from the cut tobacco pack 7. Simultaneously, the baffle plate cylinder drives the baffle plate 31 to move horizontally along the baffle plate mounting rod 32 away from the cut tobacco pack 7, exposing the discharge port 8. The cut tobacco pack 7, relying on the rolling and sliding action of the rollers on the supporting bottom surface 42, falls through the discharge port 8 onto 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, reset standby: after a single material pouring operation is completed, the material pouring cylinder and the baffle plate cylinder are reset synchronously, driving the main body 41 of the material pouring device to rotate back to a vertical position and the bearing bottom surface 42 to return to a horizontal state. At the same time, the baffle plate 31 is reset to the limit position, the slicer returns to the non-material pouring operation state, and steps S1-S5 are executed in a cycle to complete the batch cigarette pack slice pouring operation.

[0032] Preferably, the bearing bottom surface 42 is fitted with multiple rows of freely rotatable roller groups 421. The top ends of the rollers 4211 in each roller group 421 are flush and together form a rolling support surface. During non-pouring operations, the rollers 4211 passively and statically support the cut tobacco pack 7. After rotation and tilting during the pouring operation, the rollers 4211 rotate freely, reducing the friction force of the cut tobacco pack 7 sliding and being fed.

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

[0034] 1. This invention sets the bottom surface of the pouring device as a rolling bottom surface with multiple rows of freely rotating rollers embedded in it. The tops of all rollers are flush to form an integrated rolling support surface, completely abandoning the traditional fixed flat bearing bottom surface structure. In non-pouring conditions, the rollers are stationary and bear pressure, which can stably support the cut cigarette pack inside the hollow part. With the lateral limiting of the baffle plate, the vertical posture of the cigarette pack is accurately locked, ensuring the stability of the shape of the cut cigarette pack. In the pouring and flipping condition, the rollers can passively rotate freely as the cigarette pack slides down, transforming the sliding friction between the cigarette pack and the bottom surface of the device during the original pouring process into low-resistance rolling friction, greatly weakening the contact friction between the bottom surface of the device and the bottom of the cigarette pack.

[0035] Targeting the characteristics of tobacco leaves that are stacked and compressed with weak internal bonding forces, this design effectively prevents the bottom surface friction from pulling and peeling off the bottom tobacco leaves during unloading and turning. It also eliminates the problems of small tobacco fragments falling off and the main body of the tobacco bale being misaligned or tilted, ensuring that each cut tobacco bale has a complete structure and a regular shape. At the same time, it ensures that the tobacco blocks are tightly, flat, and evenly arranged on the rear conveyor belt after discharge, stably supplying material flow to subsequent leaf moistening, shredding, and drying processes, reducing material fluctuations in the process, improving the quality of finished tobacco processing, reducing the generation of broken tobacco and waste tobacco, reducing tobacco raw material loss, and adapting to continuous standardized operation of tobacco processing production lines.

[0036] 2. This invention adopts a two-way linkage pouring structure with rotating pouring device and horizontal sliding baffle plate. The two are driven independently and operate synchronously: In the non-pouring state, the pouring device is vertically arranged and the baffle plate moves forward to fit against the side wall of the cigarette pack, doubly limiting and fixing the position of the cigarette pack to prevent the cigarette pack from shifting and slipping after cutting, ensuring the safety of the slicing station operation; During the pouring operation, the pouring cylinder drives the roller pouring device to rotate 60° around the top as the axis, and the baffle plate cylinder drives the baffle plate to move away from the cigarette pack and move horizontally backward. The two-way avoidance is carried out simultaneously. Compared with the traditional single flip pouring structure, it can simultaneously widen the lateral and vertical dropping space and greatly increase the effective flow area of ​​the dropping port.

[0037] On the one hand, it avoids the problems of multiple tobacco packs sticking together and squeezing, getting stuck at the edges and corners, and clogging when feeding, making it suitable for continuous batch slicing and feeding operations on the production line and improving the efficiency of the whole machine's slicing and unloading operations; on the other hand, the non-squeezing feeding method can further avoid the stacking, squeezing, deformation, and loosening of tobacco packs, maintain the uniform shape of the fed tobacco packs, ensure that the material arrangement on the rear belt conveyor is uniform and orderly, stabilize the feed amount of the entire tobacco processing line from the source, and improve the operational stability of the entire tobacco processing production line.

[0038] 3. This invention relies on cylinders to independently drive the cutter, the unloading device, and the baffle plate for coordinated operation. The working condition switching process is closed-loop and controllable. After a single unloading is completed, the two sets of mechanisms can automatically reset and standby synchronously, completing the entire process of tobacco pack feeding, cutting, limiting, unloading, and resetting in a cycle. The overall structure of the machine is compatible with the installation dimensions of existing tobacco shredding and slicing stations, without the need for major modifications to the original production line frame and conveyor structure. The modification cost is low, and it is suitable for mass production use of both new and old tobacco shredding and slicing equipment, making it highly versatile. Attached Figure Description

[0056] Example:

[0057] This embodiment provides a slicer with a roller-type feeding device. The slicer includes a slicer body, a conveyor belt 1, a cutting blade assembly 2, a baffle assembly 3, a roller-type feeding device 4, and a receiving guide plate 5.

[0058] The roller-type material pouring device 4 is a hollow frame. The roller-type material pouring device 4 includes a material pouring device body 41 and a supporting bottom surface 42. The material pouring device body 41 and the supporting bottom surface 42 enclose a central hollow part 43.

[0059] The bearing bottom surface 42 is configured as a roller-type rolling bottom surface.

[0060] The conveyor belt 1 is located upstream of the cutter assembly 2. 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.

[0061] 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.

[0062] The roller-type material pouring device 4 is installed and fixed on the discharge side of the cutting blade assembly 2 of the slicer. The roller-type material pouring device 4 can rotate with the top of the material pouring device body 41 as the axis under the drive of the material pouring cylinder.

[0063] The material blocking assembly 3 is located on the downstream discharge side of the cutter assembly 2. The material blocking assembly 3 includes a material blocking plate 31 and a material blocking plate mounting rod 32. The material blocking plate 31 is mounted on the slicer via the material blocking plate mounting rod 32. The material blocking plate 31 can move horizontally along the material blocking plate mounting rod 32 under the drive of the material blocking plate cylinder.

[0064] The receiving guide plate 5 is located below the bearing bottom surface 42.

[0065] The slicer has two modes: non-discharging operation and discharging operation.

[0066] In the non-pouring operation state, the main body 41 of the pouring device is vertical and the bearing bottom surface 42 is horizontal. The cut cigarette pack 7 is located in the hollow part 43. The baffle plate 31 is located upstream of the baffle plate mounting rod 32. The baffle plate 31 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, so as to ensure the vertical falling posture of the cut cigarette pack 7.

[0067] In the unloading operation, the roller-type unloading device 4, driven by the unloading cylinder, rotates about the top of the unloading device body 41 in a direction away from the cut tobacco pack 7. Simultaneously, the baffle plate 31, driven by the baffle plate cylinder, moves horizontally along the baffle plate mounting rod 32 in a direction away from the cut tobacco pack 7 to expose the discharge port 8. The cut tobacco pack 7 falls through the discharge port 8 along the receiving guide plate 5. During the unloading operation, the baffle assembly 3 abuts against one side of the tobacco sheet for limitation, and the roller-type bearing bottom surface 42 supports the bottom of the tobacco sheet, working in both directions to limit the tobacco sheet's flipping angle and precisely control the vertical drop of the tobacco sheet to the discharge port.

[0068] After one material unloading operation is completed, the roller unloading device 4 and the baffle plate 31 return to the non-unloading operation state, waiting for the next unloading operation.

[0069] The roller-type material pouring device 4 can rotate 60° away from the cut tobacco pack 7 with the top of the material pouring device body 41 as the axis under the drive of the material pouring cylinder.

[0070] The bottom surface 42 of the feeding device is uniformly fitted with multiple rows of freely rotatable roller groups 421, each row of roller groups 421 including multiple rollers 4211.

[0071] The top ends of all the rollers 4211 are flush, together forming a rolling support surface for bearing and lifting the cut tobacco pack 7.

[0072] The operating method of the slicer with a roller-type feeding device described in this embodiment includes the following operating steps:

[0073] 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.

[0074] 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.

[0075] S3, Station Limiting and Bearing: After cutting, the cut cigarette pack 7 falls into the hollow part 43 of the roller-type pouring device 4 and is supported by the bearing bottom surface 42 of the roller-type pouring device 4; at this time, the slicer is in a non-pouring operation state, the main body 41 of the pouring device remains vertical, the bearing bottom surface 42 remains horizontal, and at the same time, the baffle plate 31 moves to the upstream position of the baffle plate mounting rod 32 under the drive of the baffle plate cylinder, the baffle plate 31 fits against the downstream side of the cut cigarette pack 7, limits the horizontal displacement of the cut cigarette pack 7, and locks the vertical falling posture of the cut cigarette pack 7;

[0076] S4. Linked Material Discharge: The material discharge operation is initiated. The material discharge cylinder drives the roller-type material discharge device 4 to rotate about the top of the main body 41 of the material discharge device, moving away from the cut tobacco pack 7. Simultaneously, the baffle plate cylinder drives the baffle plate 31 to move horizontally along the baffle plate mounting rod 32 away from the cut tobacco pack 7, exposing the discharge port 8. The cut tobacco pack 7, relying on the rolling and sliding action of the rollers on the supporting bottom surface 42, falls through the discharge port 8 onto 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.

[0077] The operation method also includes step S5, reset standby: after a single material pouring operation is completed, the material pouring cylinder and the baffle plate cylinder are reset synchronously, driving the main body 41 of the material pouring device to rotate back to the vertical posture, the bearing bottom surface 42 to return to the horizontal state, and at the same time the baffle plate 31 is reset to the limit position, the slicer returns to the non-material pouring operation state, and steps S1-S5 are executed in a cycle to complete the batch cigarette pack slice pouring operation.

[0078] The bearing bottom surface 42 is fitted with multiple rows of freely rotatable roller groups 421. The top ends of the rollers 4211 in each roller group 421 are flush and together form a rolling support surface. When not in the pouring operation, the rollers 4211 passively and statically support the cut tobacco pack 7. When the material is poured and rotated and tilted, the rollers 4211 rotate freely, reducing the friction of the cut tobacco pack 7 sliding and being fed.

[0079] In production, this embodiment improves the bottom of the pouring device by making it a bottom surface with rollers. When the cut tobacco leaves fall, the friction is reduced so as not to damage the overall structure of the tobacco leaves, thus ensuring the uniformity of the stacking of the tobacco leaves after falling.

[0080] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various improvements and modifications without departing from the spirit and principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

The cut tobacco pack (7) falls down along the receiving guide plate (5) through the material drop port (8).

4. The slicer with a roller-type feeding device according to claim 3, characterized in that, After a material pouring operation is completed, the roller-type material pouring device (4) and the baffle plate (31) return to the non-material pouring operation state and wait for the next material pouring operation.

5. The slicer with a roller-type feeding device according to claim 1, characterized in that, The roller-type material pouring device (4) can rotate 60° away from the cut tobacco pack (7) with the top of the main body (41) of the material pouring device as the axis under the drive of the material pouring cylinder.

6. The slicer with a roller-type feeding device according to claim 1, characterized in that, The bottom surface (42) of the feeding device is uniformly fitted with multiple rows of freely rotatable roller groups (421), each row of roller groups (421) including multiple rollers (4211).

7. The slicer with a roller-type feeding device according to claim 2, characterized in that, The tops of all the rollers (4211) are flush, together forming a rolling support surface for carrying and lifting the cut tobacco pack (7).

8. A method for operating a slicing machine with a roller-type feeding device, applied to the slicing machine with a roller-type feeding device as described in any one of claims 1-7, characterized in that, The following work steps are included: S1. Feeding and conveying: The cigarette pack (6) to be cut is conveyed downstream at a constant speed through the conveyor belt (1) until the cigarette pack (6) to be cut accurately reaches the preset cutting position of the cutter assembly (2), keeping the cigarette pack (6) to be cut in a horizontal position. 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 of the cigarette pack (6) to be cut in the horizontal state at the cutting station, and obtain the cut cigarette pack (7). S3, Station Limiting Bearing: After cutting, the cut cigarette pack (7) falls into the hollow part (43) of the roller-type pouring device (4) and is supported by the bearing bottom surface (42) of the roller-type pouring device (4); at this time, the slicer is in a non-pouring operation state, the main body (41) of the pouring device remains vertical, the bearing bottom surface (42) remains horizontal, and the baffle plate (31) moves to the upstream position of the baffle plate mounting rod (32) under the drive of the baffle plate cylinder. The baffle plate (31) fits against the downstream side of the cut cigarette pack (7), limits the horizontal displacement of the cut cigarette pack (7), and locks the vertical falling posture of the cut cigarette pack (7); S4. Linked Discharge: Start the discharge operation. The discharge cylinder drives the roller discharge device (4) to rotate around the top of the main body (41) of the discharge device in a direction away from the cut tobacco pack (7). Simultaneously, the baffle plate cylinder drives the baffle plate (31) to move horizontally away from the cut tobacco pack (7) along the baffle plate mounting rod (32), exposing the discharge port (8). The cut tobacco pack (7) falls through the discharge port (8) to the receiving guide plate (5) below, relying on the rolling and sliding action of the rollers on the bearing bottom surface (42). The material is discharged along the receiving guide plate (5). The fallen material is transported to the next processing step by another conveyor belt mechanism.

9. The method for operating a slicer with a roller-type feeding device according to claim 8, characterized in that, It also includes step S5, reset standby: after a single material pouring operation is completed, the material pouring cylinder and the baffle plate cylinder are reset synchronously, driving the main body (41) of the material pouring device to rotate and reset to a vertical posture, the bearing bottom surface (42) returns to a horizontal state, and at the same time the baffle plate (31) is reset to the limit position, the slicer returns to the non-material pouring operation state, and steps S1-S5 are executed in a cycle to complete the batch cigarette pack slice pouring operation.

10. The method for operating a slicer with a roller-type feeding device according to claim 8, characterized in that, The bearing bottom surface (42) is fitted with multiple rows of freely rotatable roller groups (421). The top ends of the rollers (4211) in each roller group (421) are flush and together form a rolling support surface. When not pouring material, the rollers (4211) passively and statically support the cut tobacco pack (7). After the material pouring operation is rotated and tilted, the rollers (4211) rotate freely, reducing the friction force of the cut tobacco pack (7) sliding and discharging.
