Description

Technical Field

[0001] This invention relates to the field of material conveying and processing equipment technology, specifically to a conveying device for meat processing with a meat mincing mechanism. Background Technology

[0002] In the field of material handling and processing, especially in operations involving online cutting of materials (such as food, wood, and composite materials), specialized conveying equipment is typically used to transport materials sequentially to the cutting station. For example, in meat processing plants, a common production process involves a conveyor line transporting large pieces of meat to equipment such as vertical band saws for sawing and cutting. However, traditional operating methods present significant safety, hygiene, and efficiency issues. Current technology usually requires operators to stand to one side of the equipment, holding the material with both hands and pushing it towards the high-speed rotating saw blade for cutting. This process poses a significant safety hazard; operators' hands are highly susceptible to injury due to material slippage or misoperation leading to contact with the saw blade. Furthermore, flying debris not only contaminates the work environment but can also cause secondary injuries to operators.

[0003] To improve the cleanliness of production lines, existing technologies have begun to focus on online cleaning of the cut surfaces. For example, another existing technology, CN120419589A, a livestock meat cutting and conveying device, provides a cutting and conveying device with cleaning components. It uses up-and-down moving cleaning rollers in conjunction with a spray system to clean the cut surfaces of the meat pieces. This technology primarily targets the removal of bone fragments and blood adhering to the surface of the meat pieces after cutting, and the cleaning action occurs after the material has been completely cut and separated. However, this technology does not address the problem of collecting the debris that is generated and splashed in all directions during the cutting process, nor does it change the high-risk operating mode of the sawing process itself. Its cleaning station is located downstream, failing to solve the hygiene and safety issues at the sawing point during the conveying process.

[0004] In summary, existing technologies have the following shortcomings: First, safety protection during processing is insufficient, requiring operators to remain close to hazardous areas; second, hygiene control is inadequate, as splattered meat scraps generated during cutting cannot be effectively collected in time, contaminating equipment and breeding bacteria; third, process integration is poor, with cutting and cleaning often being independent steps, affecting overall efficiency. Therefore, there is an urgent need for an integrated device that combines safe cutting, immediate scrap collection, and efficient conveying to fundamentally improve the safety, hygiene, and operational smoothness of processing and conveying at the sawing point. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying device for meat processing with a meat scrap collection mechanism, so as to solve the problems of low operating efficiency, serious debris splashing and pollution, and difficult and time-consuming equipment cleaning in the prior art mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for meat processing with a meat mincing mechanism, comprising: The unloading conveyor and the loading conveyor are located on the left and right sides of the processing station, respectively. The first movable conveyor platform and the second movable conveyor platform are respectively horizontally arranged on the front and rear sides of the processing station and move back and forth in the horizontal direction. The first movable conveyor platform receives the material from the feeding conveyor mechanism and pushes it through the processing station for cutting. The second movable conveyor platform receives the cut material and pushes it to the unloading conveyor mechanism. The meat mincing mechanism includes a first rotating drum and a second rotating drum, which are respectively disposed on adjacent edges of the first movable conveying platform and the second movable conveying platform, and located on the front and rear sides of the band saw blade; a scraping component is provided in the lower area of ​​the first rotating drum and the second rotating drum, and a collection and cleaning groove is provided below the scraping component.

[0007] Preferably, the driving source for the first and second rotating drums is an independent rotating drum drive motor or an integrated synchronous transmission mechanism; the synchronous transmission mechanism includes a ratchet mechanism and a synchronous wheel transmission group at the ends of the first and second rotating drums, and the reciprocating movement of the first and second movable conveying platforms drives the ratchet mechanism through the synchronous wheel transmission group, thereby driving the unidirectional rotation of the first and second rotating drums.

[0008] The above technical solution utilizes an independent rotary drum drive motor to provide stable and independent power, offering flexible control. The integrated synchronous transmission mechanism is even more ingenious and economical. It uses the reciprocating motion of the moving conveyor platform itself as a power source, converting it into unidirectional intermittent rotation of the drum through a synchronous pulley transmission group and ratchet mechanism. This design eliminates the need for an additional motor, features a compact structure, and ensures that the drum only rotates for cleaning when the moving platform in the cutting area moves, synchronizing with the cutting action and improving energy utilization efficiency and system integrity. As the drum rotates downwards, the meat scraper scrapes it into the collection trough, achieving immediate and automated collection of splattered meat scraps.

[0009] Preferably, the first movable conveyor platform and the second movable conveyor platform are driven to reciprocate by an eccentric wheel transmission mechanism; the eccentric wheel transmission mechanism includes an eccentric wheel body, an eccentric shaft hinged to the eccentric wheel body, and a drive mechanism for driving the eccentric wheel body to rotate.

[0010] By adopting the above technical solution, the eccentric wheel transmission mechanism can reliably convert the rotational motion of the eccentric wheel body into the precise linear reciprocating motion required by the movable conveyor platform. The stroke is stable and controllable, and the transmission efficiency is high. This structure is simple, durable, and easy to maintain. It can withstand the impact loads in the meat processing environment and ensures that the first and second movable conveyor platforms can coordinate and synchronously complete the handover and pushing of materials. It is the core drive unit for realizing the automated cutting process.

[0011] Preferably, the driving mechanism is an independent platform drive motor or a linked bevel gear transmission group; the eccentric wheel body forms a meshing transmission structure with the active roller of the adjacent feeding conveyor or the active roller of the unloading conveyor through the bevel gear transmission group.

[0012] Using the above technical solution, the independent platform drive motor provides independent power and control, facilitating the adjustment of the moving platform's speed and rhythm according to actual cutting needs. The linked bevel gear transmission system embodies higher integration and energy-saving principles, linking the moving platform's drive with the existing conveyor mechanism's power output shaft, achieving "one machine, multiple uses." This linked design simplifies the overall power system, reduces equipment costs and energy consumption, while ensuring mechanical synchronization between the conveyor belt's movement and the platform's pushing action, improving the system's coordination and reliability.

[0013] Preferably, the first movable conveyor platform is provided with a material positioning mechanism, the material positioning mechanism comprising: At least one guide groove is provided along the front-to-back direction of the surface of the first movable conveyor platform; A vertical insert plate is disposed on the guide groove and extends upward, the vertical insert plate being used to abut against the side of the material; A movable seat that is slidably disposed on the guide groove and the vertical insert plate; And a push-pull cross plate that moves back and forth along the guide groove to push materials in conjunction with the movable seat.

[0014] The material positioning mechanism, employing the above technical solution, is a key design feature for flexibly cutting irregular meat pieces. The guide groove and movable seat form a precise guiding foundation, while the vertical insert plate serves as a reliable positioning reference for the rear end of the material. Operators can easily and effortlessly fine-tune the material's position along the guide groove by pushing and pulling the horizontal plate to determine the thickness of each cut. This structure transforms the traditional cumbersome operation requiring manual lifting and alignment into precise, low-intensity sliding adjustments on a fixed platform, significantly reducing labor intensity and improving cutting accuracy and operational safety.

[0015] Preferably, the front end of the push-pull horizontal plate is provided with an automatic pushing device consisting of a hand push rod or an electric push rod for manual operation by the operator.

[0016] Using the above technical solutions, the manual push rod solution retains the intuitiveness and flexibility of manual operation, and is suitable for cutting small batches of non-standard meat pieces of various sizes. The electric push rod, such as an automatic pushing device composed of a cylinder or an electric linear module, provides a highly efficient automated solution for large-batch, standardized cutting. It allows for preset or programmed control of the cutting spacing, achieving continuous and precise automatic feeding, significantly improving production efficiency.

[0017] Preferably, an auxiliary lifting mechanism is provided between the movable seat and the guide groove, so that the vertical insert plate can switch between a high working position and a low feeding position; when in the low feeding position, the top of the vertical insert plate is lower than the bearing surface of the first movable conveyor platform.

[0018] By adopting the above technical solution, the height-adjustable vertical insert plate design greatly optimizes the material loading process. During loading, the insert plate is lowered to its lowest position, with its top below the platform surface, allowing the material to smoothly transition from the loading conveyor mechanism to the first movable conveyor platform without obstruction, or to be easily placed by the operator. Once the material is in place, the insert plate is raised to its highest "working position," reliably holding the rear end of the material against it. This design avoids the hassle of the material needing to "step over" or "align" with the fixed insert plate during loading, making the loading operation more convenient and faster, and improving overall work efficiency.

[0019] Preferably, the eccentric wheel transmission mechanism is connected to the first movable conveyor platform via a separate transmission structure; the separate transmission structure includes: A transmission seat connected to the end of the eccentric shaft, the transmission seat having a sliding groove; A connecting part fixed to the bottom of the first movable conveyor platform; and at least one pair of clutch damping blocks disposed between the transmission seat and the connecting portion; When the vertical insert plate of the material positioning mechanism moves downward, it pushes the clutch damping block to separate by pressing the inclined surface, thereby releasing the transmission connection between the transmission seat and the connecting part.

[0020] The aforementioned technical solution, employing a separate transmission structure, represents an innovative design that enhances the safety and convenience of human-machine interaction. Its core lies in the linkage control of the transmission clutch through the action of the "lifting plate." When material loading or manual adjustment of the material position is required, the operator presses down on the vertical plate. The downward-pressing inclined surface forces the clutch damping block to disengage, automatically and physically disconnecting the eccentric wheel transmission mechanism from the first movable conveyor platform. At this time, the platform can move freely, facilitating loading and precise positioning, completely avoiding the risks associated with equipment malfunction. After positioning, the plate is raised, and the clutch damping block re-engages under the action of a spring-loaded reset mechanism, restoring transmission. This mechanically linked clutch requires no additional electrical control, is intuitive to operate, safe and reliable, and effectively prevents pinching injuries or equipment interference caused by accidental starts.

[0021] Preferably, the processing station is equipped with a vertical band saw, which has a vertically arranged band saw blade, and a transparent protective baffle is provided in front of the operating side of the band saw blade.

[0022] Using the above technical solution, a transparent protective barrier is an important passive safety measure. Positioned directly in front of the operator, it physically isolates the work area from the hazardous area of ​​the high-speed band saw blade and flying debris. Its transparency ensures that the operator can clearly observe the cutting process and adjust their operation accordingly. The barrier effectively blocks occasional, more distant splashes of meat and bone fragments, further protecting the operator's face and body.

[0023] Preferably, the main conveyor belts of the feeding and unloading conveyors are polyurethane easy-clean belts; the bottom of the collection and cleaning trough is provided with a drain outlet, and the inner wall of the trough is provided with a water spray cleaning pipe.

[0024] Using the above technical solution, the polyurethane easy-clean conveyor belt has a smooth surface, is not easily contaminated with grease and residue, and is resistant to cutting and easy to clean, meeting the hygiene requirements of food processing. The drain outlet at the bottom of the collection tank facilitates the centralized discharge of collected meat scraps and wastewater. The water spray cleaning pipes installed on the inner wall of the tank can thoroughly wash away residues adhering to the tank walls and scraper components during production breaks or after completion, and discharge them through the drain outlet. This achieves convenient self-cleaning of the collection tank, greatly reducing the labor intensity of manual cleaning and ensuring the hygienic condition of the equipment during long-term operation.

[0025] Compared with existing technologies, the meat processing conveying equipment with a meat scrap collection mechanism provided by this invention aims to isolate the operator from the danger zone of the saw blade by redesigning the equipment layout and transmission structure, automatically collect the debris generated during cutting, and improve the automation level and operational flexibility of the cutting operation, thereby improving operational safety, hygiene, and production efficiency, and has the following significant advantages: 1. High safety: By positioning the operating position in front of the band saw (between the first and second movable conveyor platforms), the operator's hands operate on the left and right conveyor platforms, eliminating the need to reach directly into the central danger zone where the high-speed saw blade is located. Combined with the transparent protective barrier at the front, this effectively isolates the risk of flying debris and accidental contact, greatly improving operational safety.

[0026] 2. Excellent Hygiene and Cleanability: The unique debris collection mechanism, through the combination of a rotating drum, scraper, and collection trough, can instantly capture and transfer debris that splashes onto the platform edge during cutting, preventing its accumulation on the equipment surface. Combined with a polyurethane easy-clean conveyor belt and a collection and cleaning trough with water spray cleaning function, the equipment is extremely easy to clean, meeting the high hygiene standards of food processing.

[0027] 3. Flexible and labor-saving operation: The transfer and cutting process of materials between conveyor platforms is mainly completed automatically by the moving platform. Operators only need to position and load / unload materials from the front, reducing labor intensity. The material positioning mechanism is flexibly designed, allowing for both manual fine-tuning to adapt to irregular materials and automatic pushing for batch cutting, balancing efficiency and flexibility.

[0028] 4. Excellent automation and linkage: Through ingenious mechanical design, such as synchronous pulley transmission group and ratchet mechanism to drive the drum, bevel gear group to link the conveyor belt and moving platform, the motion linkage between multiple actuators is realized, reducing the use of independent motors, with compact structure and simple and reliable control.

[0029] 5. User-friendly human-machine interface: The linkage design of the split transmission structure and the liftable positioning plate allows the platform drive to be temporarily disconnected during loading to facilitate material placement; the linkage can be quickly restored when needed, resulting in a smooth operation process and improved ease of use and safety.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-10 This invention provides the following technical solution. The following description, using the application of this conveying equipment in meat processing as an example, will be detailed with reference to the accompanying drawings. It is understood that this invention is also applicable to other material processing scenarios that require cutting and generate debris. Example 1: Please see Figure 1-3 This embodiment provides a basic structural implementation of a conveying device for meat processing with a meat mince collection mechanism.

[0034] The main frame of the equipment is fixedly installed on the ground. The vertical band saw 10 is fixedly installed in the middle of the frame by bolts, and its vertically arranged band saw blade 11 is driven by an independent sawing motor to perform high-speed cyclic cutting motion.

[0035] The unloading conveyor 30 and the loading conveyor 20 are symmetrically arranged on the left and right sides of the vertical band saw 10 via their respective supports, and their conveying surfaces are at the same horizontal level. The loading conveyor 20 is used to transport whole pieces of material to be cut (such as half pig carcasses, large pieces of beef, etc.) from the upstream process or storage area. The unloading conveyor 30 is used to transport the cut meat pieces to the downstream packaging or refrigeration process. In this embodiment, the main conveyor belts of the loading conveyor 20 and the unloading conveyor 30 are preferably made of smooth polyurethane easy-clean belts, which are easy to clean and meet food hygiene standards.

[0036] The first movable conveyor platform 40 and the second movable conveyor platform 50 are two rectangular platforms with essentially the same structure. The first movable conveyor platform 40 is slidably fitted onto a first linear guide rod fixed to the equipment table and arranged in the left-right direction via a linear slide mounted on its bottom. Similarly, the second movable conveyor platform 50 is slidably mounted on a second linear guide rod via a linear slide on its bottom. The first and second linear guide rods are precisely parallel to each other on the front and rear sides of the band saw blade 11, respectively. Each movable conveyor platform is driven by its own independent platform drive motor through a ball screw or belt drive mechanism, achieving precise and smooth left-right reciprocating movement along the guide rod.

[0037] The starting (right) position of the first movable conveyor platform 40 is adjacent to the ending (left) position of the feeding conveyor mechanism 20, and its left limit position of travel must ensure that the material can completely pass through the band saw blade 11. The starting (right) position of the second movable conveyor platform 50 is located in the area directly behind and slightly to the right of the band saw blade 11, and is used to receive the cut meat pieces. Its left limit position of travel must be adjacent to the starting (right) position of the unloading conveyor mechanism 30.

[0038] The minced meat collecting mechanism 60 is one of the core features of this invention. For example... Figure 8 As shown, a first rotating drum 61 is horizontally mounted on the first movable conveyor platform 40 near the edge of the band saw blade 11 (i.e., the edge adjacent to the second platform) via a bearing seat. Similarly, a second rotating drum 62 is horizontally mounted on the second movable conveyor platform 50 near the edge of the band saw blade 11. The axes of the first rotating drum 61 and the second rotating drum 62 are parallel, and their cylindrical outer surfaces are not lower than the bearing surface of their respective platforms, ensuring that splattered meat scraps fall onto the surface of the rotating drums first, rather than into the gaps between the platforms. The first rotating drum 61 and the second rotating drum 62 are each driven by two independent small rotating drum drive motors, allowing for slow unidirectional rotation.

[0039] Below each rotating drum, a fixed scraper 63 is provided. The scraper 63 can be made of rubber or plastic, and its blade maintains slight contact with the surface of the rotating drum. Below the scraper 63, on the main platform of the equipment, a narrow groove extending along the width of the equipment is formed, constituting a collection and cleaning trough 64. The bottom of the collection and cleaning trough 64 is inclined to one side and has a drain outlet, which can be connected to a sewer or a waste collection bin.

[0040] Additionally, safety and cleaning accessories may include a protective baffle 100 and a water spray cleaning system; Protective shield 100: A transparent polycarbonate protective shield 100, approximately covering the sawing area, is installed directly in front of the band saw blade 11 (i.e., on the side where the operator stands) via a hinge or adjustable bracket. The shield can be designed to be slightly tilted, effectively blocking flying debris without obstructing the operator's view. Warning signs may be placed on the upper edge of the shield. This shield, together with the movable platform and safety clutch structure, constitutes multiple layers of safety protection.

[0041] Water spray cleaning system: A water spray cleaning pipe, preferably made of stainless steel, is installed on the inner wall of the collection and cleaning tank 64, arranged along the length of the tank, with multiple fan-shaped nozzles spaced apart on the pipe. This pipeline is connected to the clean water pipeline in the factory via a solenoid valve. The solenoid valve can be manually controlled by a button on the control cabinet, or it can be connected to an automatic control program to automatically start rinsing for a certain period of time after the end of each workday. The wastewater after rinsing is discharged directly from the drain outlet at the bottom of the tank.

[0042] Workflow: Initial state: The first movable conveyor platform 40 is located at the far right (material receiving position), and the second movable conveyor platform 50 is located slightly to the left (material receiving and cutting position).

[0043] Loading and Pushing: The operator moves the material from the loading conveyor 20 to the adjacent first movable conveyor platform 40. The operator is positioned in front of the equipment (between the loading conveyor 20 and the unloading conveyor 30) and can manually adjust the material position. Subsequently, the first platform drive motor starts, driving the first movable conveyor platform 40 and the material on it to move uniformly to the left, so that the material passes through the high-speed rotating band saw blade 11, completing one cut.

[0044] Meat scrap collection: During the cutting process, most of the splattered meat scraps and debris fall onto the surfaces of the first rotating drum 61 and the second rotating drum 62. The drum drive motor starts, causing the drums to rotate slowly, moving the parts with meat scraps to the lower part. When it reaches the scraper 63, the meat scraps are scraped off and fall into the collection and cleaning trough 64 below.

[0045] Receiving and Discharging: The cut meat pieces fall onto the second movable conveyor platform 50, which moves immediately after them. As the first platform completes its push and returns to its original position to the right, the second movable conveyor platform 50 starts moving to the left, smoothly transferring the cut meat pieces to the side of the discharge conveyor mechanism 30. Operators then assist in transferring the meat pieces to the discharge conveyor mechanism 30 for transport. The second platform then returns to its original position to the right, ready for the next receiving operation.

[0046] Cleaning: During work breaks or after completion, the valve of the water spray cleaning pipe installed on the inner wall of the collection and cleaning tank 64 can be opened. High-pressure water will flush the tank wall and scraper 63, and the sewage will be discharged from the drain outlet, achieving automatic cleaning.

[0047] This embodiment achieves fully automated material loading, cutting, receiving, and unloading through the alternating reciprocating motion of two moving platforms. Operators only need to perform auxiliary positioning and monitoring in the safe area in front, and their hands only need to assist in moving the material outside the sawing danger zone. At the same time, the rotary meat scrap collection mechanism 60 enables real-time, online collection of cutting splatter, keeping the equipment and environment clean.

[0048] Example 2: Based on the basic structure of Embodiment 1, this embodiment provides a power transmission scheme with high mechanical linkage and compact structure.

[0049] like Figures 4-6 and Figures 9-10 As shown, in this embodiment, the independent drive motors for the first movable conveyor platform 40 and the second movable conveyor platform 50 are eliminated, as are the independent drive motors for the first drum 61 and the second drum 62.

[0050] 1. Collaborative driving force of the event platform: The drive mechanism 73 employs a linked bevel gear transmission assembly 731. Specifically, a drive shaft is connected to the shaft end of the drive roller of the feeding conveyor mechanism 20 (or the shaft end of the drive roller of the unloading conveyor mechanism 30) via a coupling, and a drive bevel gear is keyed to the other end of the drive shaft. A driven bevel gear is installed in 90-degree angle meshing with the drive bevel gear, and the axis of the driven bevel gear coincides with the axis of the eccentric wheel body 71. The eccentric wheel body 71 is fixedly mounted on the shaft of the driven bevel gear.

[0051] The eccentric wheel body 71 is mounted on the frame via bearings, and an eccentric shaft 72 is mounted on it. The other end of the eccentric shaft 72 is connected to the connecting part 92 at the bottom of the first movable conveyor platform 40 via a sliding groove. Thus, when the motor of the feeding conveyor mechanism 20 starts and the conveyor belt runs, the power drives the eccentric wheel body 71 to rotate via the bevel gear transmission group 731. The circular motion of the eccentric wheel body 71 is converted into the left-right reciprocating linear motion of the first movable conveyor platform 40 via the eccentric shaft 72. The second movable conveyor platform 50 can be driven by an identical set of eccentric wheel transmission mechanisms 70, whose power can come from the drive roller of the unloading conveyor mechanism 30. By designing the initial phase angle of the eccentric wheel, the coordination of the movement sequence of the two platforms is ensured.

[0052] 2. The linkage drive of the rotating drum: The first rotating drum 61 and the second rotating drum 62 are driven by an integrated synchronous transmission mechanism. Taking the first rotating drum 61 as an example (the same applies to the second rotating drum 62).

[0053] A left-right guide rail is provided on the frame platform below the first movable conveyor platform 40, serving as the movable input part of the synchronous pulley transmission group 66. A ratchet mechanism 65 is installed at the end of the first rotating drum 61 as the output part of the first rotating drum 61. Two bevel gears with a 90-degree angle meshing are provided between the shaft end of the ratchet mechanism 65 and the shaft end of the synchronous pulley for meshing transmission. During the movement of the platform, the synchronous pulley rolls in the guide rail, periodically driving the pawl of the ratchet mechanism 65 through meshing transmission, thereby pushing the ratchet and the first rotating drum 61 to rotate.

[0054] Due to the unidirectional nature of the ratchet, regardless of whether the platform pushes material to the left or retracts to the right, the drum rotates intermittently in only one direction (even the direction in which the surface with meat scraps rotates downwards). The drive structure of the second drum 62 is symmetrically arranged with that of the first drum 61, and is driven by the movement of the second movable conveyor platform 50 through another set of synchronous wheel transmission group 66 and ratchet mechanism 65.

[0055] Advantages of this embodiment: The drive system for the moving platform and the meat-collecting drum is seamlessly integrated with the existing conveying mechanism's power source, achieving synchronous drive by adding only mechanical components such as gears, eccentric wheels, and ratchet. This greatly simplifies the electrical control system, reduces the number of independent motors used, and lowers manufacturing costs and energy consumption. Simultaneously, the mechanical linkage ensures a high degree of synchronization and reliability of the actions of each actuator, naturally coordinating platform movement with the meat-collecting action.

[0056] Example 3: Optimized Scheme with Lifting Positioning and Safety Clutch This embodiment further optimizes the ease of operation and safety of equipment use for material positioning, based on embodiment one or two.

[0057] like Figure 3 As shown, the material positioning mechanism 80 in this embodiment is designed as follows: A guide groove 81 is provided on the platform of the first movable conveyor platform 40, and the guide groove 81 is set along the front-to-back direction of the platform. The movable seat 82 sits on the guide groove 81 through the slot at its bottom and can slide back and forth along the guide groove 81. The vertical insert plate 83 is inserted into the guide groove 81 as a whole, and the vertical insert plate 83 can be connected to the movable seat 82 through a lever-type pressing lever. Rotating the lever causes the vertical insert plate 83 to press down, forming a simple auxiliary lifting and adjustment mechanism. When it is necessary to load materials, the operator can rotate the lever to press down the vertical insert plate 83, so that its top is lower than the bearing surface of the first movable conveyor platform 40, which is the "low-position loading position". After the materials are placed, the lever is pulled in the opposite direction, and the vertical insert plate 83 can elastically return to the vertical "high-position working position", and its plate surface can be close to the right end of the material for easy material pushing.

[0058] The push-pull horizontal plate 84 is fixedly connected to the movable seat 82 by bolts, and the vertical insert plate 83 is set through the push-pull horizontal plate 84 and the movable seat 82. The operator can hold the push rod at the front end of the push-pull horizontal plate 84 and easily push the entire movable seat 82 and push-pull horizontal plate 84 assembly back and forth, thereby precisely adjusting the front and back position of the material on the platform to determine the cutting thickness. The push rod at the front end of the push-pull horizontal plate 84 can also be replaced with an electric push rod. The cylinder of the electric push rod is fixed to the front end of the platform, and the end of the push rod is connected to the movable seat 82 to realize automatic feeding of the material position.

[0059] like Figure 7 As shown, a key improvement in this embodiment is the separate transmission structure 90, which securely links the material positioning operation with the platform drive.

[0060] The end of the eccentric shaft 72 is slidably connected to the transmission seat 91, and a long sliding groove is provided on the transmission seat 91.

[0061] The connecting part 92, fixed to the bottom of the first movable conveyor platform 40, has its main body located on the front and rear sides of the transmission seat 91. It is in contact with the front and rear sides of the transmission seat 91 through a pair of clutch damping blocks 93. A compression spring is installed between the clutch damping blocks 93 and the connecting part 92, so that they tend to move closer to each other under normal conditions, thereby tightly clamping the transmission seat 91 and realizing the transmission of power from the transmission seat 91 to the connecting part 92. This is the "transmission engaged" state.

[0062] A wedge-shaped head extends from the lower end of the vertical insert plate 83 of the material positioning mechanism 80. When the vertical insert plate 83 is in the high working position, the wedge-shaped head is located above the clutch damping block 93 and is not in contact with it. During the linkage process, when the operator needs to load materials, the vertical insert plate 83 is pressed down to the low position. During the pressing process, the wedge-shaped head at the end of the vertical insert plate 83 descends and inserts between the inclined surfaces of a pair of clutch damping blocks 93. As the insert plate continues to press down, the wedge-shaped head pushes the two clutch damping blocks 93 to both sides, causing them to disengage from the transmission seat 91. At this point, the transmission is physically cut off, the first movable conveying platform 40 is disengaged from the eccentric wheel transmission mechanism 70, and the platform can be freely pushed or kept stationary, facilitating material placement and adjustment. After the materials are placed and the vertical insert plate 83 is raised and reset, the wedge-shaped head of the vertical insert plate 83 is pulled out, and the clutch damping block 93 re-closes and clamps the transmission seat 91 under the action of the internal spring, and the transmission is automatically restored.

[0063] Advantages of this embodiment: Easy loading: The retractable positioning plate eliminates loading obstacles, and large pieces of material can be easily pushed into the platform.

[0064] Intrinsic safety: It implements mechanical interlock safety logic. As long as the plug plate is not raised, the platform cannot be driven, completely preventing the risk of crushing injury caused by accidental equipment start-up when the operator's hands are in the platform area.

[0065] Smooth operation: The lifting and clutch are linked without the need for additional buttons or switches, which is ergonomic and improves operating efficiency.

[0066] Furthermore, the devices in the above embodiments can adopt multiple control modes as needed: Manual mode: Operators can control the start / stop of the loading / unloading conveyor, the forward / backward / stop of the moving platform, the rotation of the drum, and the opening / closing of the cleaning valve via buttons on the control panel. This mode is flexible and suitable for non-standard products.

[0067] Semi-automatic cycle mode: After the operator places the material and presses the "start" button, the equipment automatically completes one complete cycle of "first platform forward cutting, second platform forward unloading, and both platforms retracting". The cutting thickness is set manually by the material positioning mechanism 80.

[0068] Fully automatic mode: Linked with the upstream conveyor line, the material is automatically positioned. The material positioning mechanism 80 uses an electric push rod to automatically feed according to the preset thickness. The equipment works continuously in a cycle to achieve unattended batch cutting.

[0069] The electrical control system can integrate emergency stop buttons, safety light curtains, etc., which are installed on the columns on both sides of the protective baffle 100 to further ensure safety.
