Description

Technical Field

[0001] This utility model relates to the field of cover forming technology, and in particular discloses a nitrocellulose inner cover forming mechanism. Background Technology

[0002] The molding of nitrocellulose inner caps involves several processes, including roll cutting, sheet hot pressing, punching, and stacking. The seamless integration of these processes and the precision of the machining are crucial to production. Existing molding equipment generally suffers from fragmented processes and low automation. Processes such as cutting, hot pressing, and punching rely heavily on manual handling, increasing costs and risks, and making it susceptible to accuracy errors. Furthermore, the lack of efficient sheet stacking and transfer mechanisms hinders automated waste material rewinding and cutting, and the inability of transfer mechanisms to handle materials synchronously results in low production efficiency and slow cycle times. Therefore, developing a multi-process, highly automated nitrocellulose inner cap molding mechanism is an urgent need to address the shortcomings of existing equipment. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a nitrocellulose inner cover molding mechanism.

[0004] To achieve the above objectives, this utility model provides a nitrocellulose inner cover forming mechanism, including a frame, a punching mechanism, a hot pressing forming mechanism, a punching mechanism, and a transfer mechanism mounted on the frame. The punching mechanism includes a punching drive, a punching assembly that cooperates with the output end of the punching drive, and a punching worktable mounted below the punching mechanism. The punching drive drives the punching assembly to punch the roll material placed on the punching worktable to form a sheet. The transfer mechanism transfers the sheet material on the punching worktable to the hot pressing forming mechanism for hot pressing, and then transfers the hot-pressed sheet material to the punching mechanism for punching.

[0005] Using a frame as the mounting base, a punching mechanism, a hot pressing mechanism, a punching mechanism, and a transfer mechanism are integrated on it. The punching drive drives the punching assembly to punch the roll material placed on the punching worktable to form a sheet material. The transfer mechanism then sequentially completes the transfer of the sheet material to the hot pressing mechanism for hot pressing and to the punching mechanism for punching operations. This setup, through the integration of multiple mechanisms and the coordination of automated transfer, realizes continuous processing of nitrocellulose inner caps from roll material to finished product, effectively reducing manual intervention, improving production efficiency and product size consistency, and ensuring processing accuracy and production stability.

[0006] The transplanting mechanism includes a first moving mechanism and a second moving mechanism. The first moving mechanism is located on the side of the punching mechanism and is used to transfer the punched sheet to the hot pressing forming mechanism. The hot pressing forming mechanism and the punching mechanism are arranged in the same direction. The second moving mechanism is located on the side of the hot pressing forming mechanism and the punching mechanism. The second moving mechanism is used to transfer the hot-pressed sheet formed by the hot pressing forming mechanism to the punching mechanism and to transfer the punched sheet to the punching mechanism for unloading.

[0007] The first moving mechanism is located on the side of the punching mechanism and is used to transfer the punched sheet to the hot pressing forming mechanism. The hot pressing forming mechanism and the punching mechanism are arranged in the same direction. The second moving mechanism is located on the side of the hot pressing forming mechanism and the punching mechanism and is responsible for transferring the hot-pressed sheet to the punching mechanism and the punched sheet to the unloading station. This structure, through the division of labor and cooperation of the two moving mechanisms, adapts to the arrangement of each processing mechanism, shortens the transfer path, improves the transfer accuracy, avoids the sheet from being deviated or damaged during the transfer process, further ensures the continuity and automation of the overall processing flow, and improves production efficiency and product qualification rate.

[0008] The frame is equipped with a movable guide post, and the punching assembly and punching worktable are mounted on the movable guide post. The punching worktable includes a punching plate fixed on the movable guide post and a spring buffer suction cup located below the punching plate. The punching plate has a circular hole. The spring buffer suction cup includes an elastic drive and a positioning block mounted on the elastic drive. The positioning block is accommodated in the circular hole. External coil material is fed onto the punching plate. When the punching drive drives the punching assembly to move downward along the guide post to approach the punching plate, the positioning block is compressed by the elastic drive and together with the punching assembly punches the external coil material placed on the punching plate to form a sheet. When the punching drive drives the punching assembly to move upward away from the punching plate, the elastic drive resets, and the positioning block pushes the sheet onto the reference surface of the punching plate to await transport to the next station.

[0009] The frame is equipped with movable guide pillars, and both the punching assembly and the punching worktable are mounted on the movable guide pillars. The punching worktable includes a punching plate fixed on the movable guide pillar and a spring-loaded suction cup located below it. The punching plate has a circular hole, and the spring-loaded suction cup consists of an elastic drive element and a positioning block disposed thereon, with the positioning block housed within the circular hole. After the external coil material is fed onto the punching plate, the punching drive element drives the punching assembly to move downwards along the movable guide pillar towards the punching plate. Simultaneously, the positioning block is compressed by the elastic drive element and works in conjunction with the punching assembly to punch the coil material into a sheet. When moving upwards away from the punching plate, the elastic drive component resets, and the positioning block pushes the sheet material up to the reference surface of the punching plate for transport to the next station. This structure ensures the motion guidance accuracy of the punching component and the worktable through the moving guide post. The positioning block of the spring buffer suction cup cooperates with the elastic drive component to achieve precise positioning and buffer protection during punching, avoiding deformation or damage to the coil / sheet material during punching. It can also automatically push the sheet material up after punching, facilitating subsequent handling operations. This effectively improves the punching quality, positioning accuracy, and loading / unloading efficiency, ensuring product size consistency and smooth processing flow.

[0010] The punching assembly includes a first movable plate slidably mounted on a movable guide post and a clamping component mounted on the first movable plate. The first movable plate is connected to the output end of the punching drive. The punching drive drives the first movable plate to move up and down reciprocally to move the clamping component closer to or away from the punching worktable. The clamping component includes a clamping drive, a clamping rod connected to the output end of the clamping drive, and a clamping block mounted at the other end of the clamping rod. When the first movable plate approaches the punching worktable, the clamping drive drives the clamping rod to move downward to engage the clamping block with the positioning block to punch the external coil material.

[0011] During operation, the punching drive unit drives the first moving plate to move up and down along the moving guide post, causing the clamping component to move closer to or away from the punching worktable. When the first moving plate approaches the punching worktable, the clamping drive unit drives the clamping rod to move downward, causing the clamping block to dock with the positioning block of the punching worktable, and together punching the external coil material. This structure ensures punching stability through the guided movement of the first moving plate along the moving guide post, and the precise docking of the clamping component and the positioning block achieves dual positioning and clamping during coil material punching, effectively preventing deviation and wrinkles during coil material punching, improving the punching accuracy and edge flatness of sheet material. At the same time, the coordinated action of the punching drive unit and the clamping drive unit ensures that the punching process is orderly and controllable, further ensuring the consistency of product dimensions and the smoothness of subsequent processing.

[0012] The forming mechanism further includes an alternating transfer mechanism disposed between the punching mechanism and the transfer mechanism, and a stacking mechanism disposed on the frame. The stacking mechanism is used to stack the sheet metal already punched on the punching workbench onto the alternating transfer mechanism. The alternating transfer mechanism includes a first support frame, a first material alternating transfer platform disposed on the first support frame, a second material alternating transfer platform, and a transfer moving component. The transfer moving component is located below the first material alternating transfer platform and the second material alternating transfer platform, and includes a transfer guide rail, a first transfer plate, a front and rear moving cylinder for driving the first transfer plate to reciprocate, and a... A lifting cylinder is placed on the first transfer plate, and a lifting block is connected to the output end of the lifting cylinder. When the stacking mechanism transports the sheet material to the first material interleaving transfer platform, and the stacked sheet material reaches a preset quantity, the front and rear moving cylinder drives the first transfer plate to move along the transfer guide rail to directly below the first material interleaving transfer platform. The lifting cylinder drives the lifting block to move upward, lifting the stacked sheet material on the first material interleaving transfer platform. The front and rear moving cylinder continues to drive the first transfer plate to move to the second material interleaving transfer platform. The lifting cylinder drives the lifting block to reset downward, placing the stacked sheet material in the sheet material limiting block of the second material interleaving transfer platform.

[0013] A moving channel is provided between the first material transfer station and the second material transfer station. The moving channel between the two transfer stations provides smooth moving space for the transfer moving parts, which work together with the coordinated operation of the two transfer stations and the transfer moving parts.

[0014] During operation, the stacking mechanism transports sheet materials to the first material interleaving transfer platform. After stacking to a preset quantity, the forward and backward moving cylinders drive the first transfer plate to move along the transfer guide rail to directly below the first material interleaving transfer platform. The lifting cylinder drives the lifting block to move upward and lift the stacked sheet materials. The forward and backward moving cylinders continue to drive the first transfer plate to move to directly below the second material interleaving transfer platform. The lifting cylinder drives the lifting block to move downward and reset, placing the stacked sheet materials within the sheet material limiting block of the second material interleaving transfer platform. This structure achieves quantitative stacking of sheet materials through the stacking mechanism. The double transfer platforms of the interleaving transfer mechanism and the transfer moving parts work together to achieve alternating transfer of stacked sheet materials, avoiding mutual waiting between punching and subsequent transfer operations, ensuring processing continuity. At the same time, the precise coordination between the sheet material limiting block and the lifting and moving mechanisms prevents the stacked sheet materials from shifting or scattering, improving the stability and transfer efficiency of sheet material transfer, and laying the foundation for subsequent automated processing.

[0015] The stacking mechanism includes a slice transport guide rail mounted on the frame, a slice transport section, and a second drive unit that drives the slice transport section to reciprocate on the slice transport guide rail. The slice transport section includes a sliding support slidably mounted on the slice transport guide rail and a suction section fixedly mounted on the sliding support. The suction section includes an explosion-proof cylinder fixed on the sliding support and a vacuum suction cup assembly connected to the output end of the explosion-proof cylinder. When the spring-buffered suction cup lifts the slice, the control center sends a suction command to the stacking mechanism. The second drive unit drives the slice transport section to move along the slice transport guide rail to directly above the punching position of the punching worktable. The explosion-proof cylinder drives the vacuum suction cup to move downward to fit against the upper surface of the slice. The vacuum generator starts to generate negative pressure, and the suction cup tightly grips the slice. Subsequently, the explosion-proof cylinder resets, causing the slice to rise. The second drive unit drives the slice transport section to move along the slice transport guide rail to the first material cross-transfer platform stacking position of the cross-transfer mechanism. Upon arrival, the vacuum generator of the explosion-proof cylinder stops working, releasing the slice and placing it on the first material cross-transfer platform.

[0016] During operation, after the spring-loaded suction cup lifts the sheet material, the control center sends a suction command to the stacking mechanism. The second drive unit drives the slicing transport unit to move along the slicing transport guide rail to directly above the punching position of the punching worktable. The explosion-proof cylinder drives the vacuum suction cup to move downwards until it is in contact with the upper surface of the sheet material. The vacuum generator starts to generate negative pressure, causing the suction cup to firmly grip the sheet material. Subsequently, the explosion-proof cylinder resets, causing the sheet material to rise. The second drive unit continues to drive the slicing transport unit to move along the guide rail to the stacking position of the first material cross-transfer platform of the cross-transfer mechanism. Upon arrival, the vacuum generator... The process stops, releasing the sheet material and placing it on the transfer platform. This structure adapts to the safety processing requirements of nitrocellulose materials through an explosion-proof cylinder. The vacuum suction cup assembly avoids damage to the sheet material by using negative pressure adsorption. Combined with the guiding effect of the sheet material transport guide rail, it ensures the accuracy of movement. This enables automated, non-destructive handling and quantitative stacking of sheet material from the punching worktable to the staggered transfer mechanism. It effectively connects the punching and transfer processes, improves stacking efficiency and sheet material integrity, while reducing the risk of human intervention and ensuring production safety and smooth and continuous processing.

[0017] The first moving mechanism includes a second support frame, a moving block mounted on the second support frame, a first moving drive component that drives the moving block to reciprocate on the second support frame, and a gripping part fixedly mounted on the moving block. The gripping part includes a gripping bracket, a suction cylinder mounted on the gripping bracket, a suction plate connected to the output end of the suction cylinder, and multiple sets of auxiliary gripping components mounted on the side of the gripping bracket. The gripping part is located above the staggered transfer mechanism. After the sheet material is stacked, the suction cylinder drives the suction plate to move downwards and approach the sheet material to pick it up. The auxiliary gripping components are used to abut against the sides of multiple sets of sheet material to assist in positioning. After the suction plate completes the picking up, the first moving drive component drives the gripping part to move to the hot pressing forming mechanism to place the sheet material in the hot pressing forming mechanism to wait for hot pressing.

[0018] After the sheet materials are stacked, the suction cylinder drives the suction plate to move downwards and approach the sheet materials to pick them up. The auxiliary gripping parts abut against the sides of multiple sets of sheet materials to achieve auxiliary positioning. After the sheet materials are picked up in cooperation with the suction plate, the first moving drive unit drives the gripping part to move to the hot pressing forming mechanism and place the sheet materials in the mechanism to wait for hot pressing. This structure achieves dual protection of sheet material adsorption and fixation and side positioning through the synergistic action of the suction plate and multiple sets of auxiliary gripping parts, effectively preventing the sheet materials from shifting, scattering or being damaged during the transfer process. Combined with the precise guidance of the first moving drive unit and the second carrier frame, the transfer positioning accuracy and stability are improved, and the staggered transfer and hot pressing forming processes are efficiently connected, further enhancing the automation continuity of the processing flow and ensuring product size consistency and production efficiency.

[0019] The auxiliary gripping component includes a first straight rod connected to the bottom of the gripping bracket. The end of the first straight rod away from the bottom of the gripping bracket has a bent portion, which is used to abut against the sheet material.

[0020] The hot pressing forming mechanism includes a third support frame, a stamping electric cylinder mounted on the third support frame, a stamping block slidably mounted on the third support frame, an upper pressing block mounted on the stamping block, and a lower pressing block fixedly mounted on the third support frame. The output end of the stamping electric cylinder is connected to the stamping block. The stamping electric cylinder drives the stamping block to move downward, causing the upper pressing block to approach the lower pressing block, and hot pressing the sheet material placed in the lower pressing block.

[0021] During operation, the electric cylinder drives the stamping block to move downwards, bringing the upper pressure block closer to the lower pressure block, and hot-pressing the sheet material placed in the lower pressure block. This structure achieves precise power output through the electric cylinder, and with the sliding guide of the stamping block and the corresponding setting of the upper and lower pressure blocks, it ensures stable pressure and accurate positioning during the hot pressing process, effectively improving the forming accuracy and shape consistency of the nitrocellulose inner cover. Moreover, the overall structure is simple and stable, and the action response is rapid. It can efficiently connect the preceding transfer process and the subsequent punching process, ensuring the stability and production efficiency of hot pressing.

[0022] The punching mechanism includes a fourth support frame, a punching cylinder mounted on the fourth support frame, a punching part mounted on the fourth support frame, and a punching support platform mounted below the punching part; the punching cylinder is used to drive the punching part to move up and down on the fourth support frame to approach or move away from the punching support platform, and to punch the sheet material placed on the punching support platform.

[0023] The punching cylinder provides stable power output, and the fourth support frame ensures precise assembly and positioning of each component, ensuring positional accuracy and pressure uniformity during the punching process. This effectively improves the hole diameter accuracy and edge regularity of the inner cover punching. The overall structure is compact and the action response is efficient, allowing for smooth connection between hot pressing and subsequent blanking processes, ensuring the continuity of the processing flow, and further improving production efficiency and product qualification rate.

[0024] The forming mechanism also includes a feeding component, which is arranged in parallel with the hot pressing forming mechanism and the punching mechanism. The second moving mechanism is located on the side of the feeding component, the hot pressing forming mechanism, and the punching mechanism. The feeding component includes a rod guide rail, a turntable mounted on the rod guide rail, and a rod motor that drives the turntable to move up and down on the rod guide rail. The turntable is equipped with an incoming material sensor, and the bottom of the rod guide rail is equipped with a limit sensor. The turntable includes a base, multiple material trays mounted on the base, and a rotating motor that drives the turntable to rotate. When the punched sheet is transferred to the material tray by the second moving mechanism, the incoming material sensor senses the incoming material and generates an incoming material command. The control center controls the rod motor to drive the turntable to move downward. After continuously stacking to a preset height, the turntable descends to the bottom of the rod guide rail and triggers the limit sensor. The limit sensor senses the material and generates a full material command. The control center controls the rotating motor to drive the base to rotate according to the full material command, rotating the empty material tray to the stacking position to wait for stacking.

[0025] During operation, the punched sheet material is transferred to the material tray via the second moving mechanism. Upon receiving the material, the incoming material sensor generates an incoming material command. The control center controls the rod motor to drive the turntable downwards. After the sheet material is continuously stacked to a preset height, the turntable descends to the bottom of the rod guide rail and triggers the limit sensor. The limit sensor generates a full material command. Based on this command, the control center controls the rotating motor to drive the chassis to rotate, moving the empty material tray to the stacking position to await subsequent stacking. This structure adapts to the transfer path of the second moving mechanism through the parallel arrangement of the unloading component and each processing mechanism. Multiple material trays and the rotation and lifting actions of the turntable work together to achieve continuous automated stacking of sheet material. The accurate feedback from the incoming material sensor and the limit sensor ensures that the stacking height is controllable and the tray is changed in a timely manner, avoiding sheet material overflow or scattering. This not only ensures the stability of the unloading process and the integrity of the product, but also eliminates the need for manual intervention in tray changing, further improving the overall automation level and continuous operation efficiency of production.

[0026] The second moving mechanism includes a front-to-back moving component, a left-to-right moving component disposed on the front-to-back moving component, a movable mounting base disposed on the left-to-right moving component, a vertical moving component disposed on the movable mounting base, and a suction cup transporter disposed on the vertical moving component. There are three sets of suction cup transporters, which are arranged at intervals along the arrangement direction of the hot pressing forming mechanism, the punching mechanism, and the unloading component. They are respectively adapted to the unloading station of the hot pressing forming mechanism, the infeed and unloading station of the punching mechanism, and the infeed station of the unloading component, and are used to synchronously or sequentially adsorb and fix the sheet material at each station to achieve continuous transport.

[0027] Through the coordinated operation of multi-directional moving components, the suction cup transporter achieves precise positioning and flexible movement. The corresponding layout design of the three sets of suction cup transporters and each workstation can synchronously connect the hot pressing unloading, punching infeed and unloading, and unloading feeding processes, avoiding the waiting gap of single-station transport, greatly improving transport efficiency and process continuity. At the same time, suction transport can reduce sheet material damage, further ensuring product integrity and production stability, and strengthening the automated continuous operation capability of the integral molding core.

[0028] The punching mechanism is also equipped with a winding mechanism on its side, and a waste cutting mechanism is also provided below the winding mechanism. The punched waste roll is wound up to the waste cutting mechanism via the winding mechanism. The waste cutting mechanism includes a waste collection box, a first cutting part and a second cutting part disposed above the waste collection box, a cutting cylinder for driving the first cutting part to move closer to the second cutting part, a first pressing component disposed on the first cutting part, a pressing cylinder for driving the first pressing component to press the film, and a swinging mechanism disposed on the side of the waste collection box. The pressing cylinder drives the first pressing component to press the waste roll film, and the cutting cylinder drives the first cutting part to move closer to the second cutting part to cut the waste roll film. When a certain amount is cut, the swinging mechanism drives the waste collection box to shake to shake the waste evenly.

[0029] Through the coordinated design of the winding mechanism and the cutting mechanism, the automatic collection and quantitative cutting of punching waste is realized. The pressing component presses and cooperates with the cutting action to ensure that the waste is cut neatly and avoids deviation. The swing mechanism ensures that the waste is collected evenly. There is no need for frequent manual handling of waste, which not only improves the cleanliness of the production environment, but also reduces the interruption time of the process, and further ensures the continuity and automation efficiency of the overall processing flow.

[0030] The winding mechanism includes a fifth support frame, a winding roller rotatably mounted on the fifth support frame, a winding drive motor that drives the winding roller to rotate, and a guide roller located between the punching mechanism and the winding roller. The winding mechanism is correspondingly located on the side of the punching mechanism and above the waste cutting mechanism. During operation, the waste roll generated by the punching mechanism is guided by the guide roller, and the winding drive motor drives the winding roller to rotate continuously, winding the waste roll in an orderly manner and conveying it to the waste cutting mechanism below. This achieves automated continuous winding of waste, efficiently connects the punching mechanism and the waste cutting mechanism, reduces the impact of waste accumulation on the processing flow, further improves the automation of the entire waste treatment process, and enhances the cleanliness of the production environment and overall operating efficiency.

[0031] The swing mechanism includes a swing bracket fixed on the frame, a swing drive component (such as a swing cylinder or eccentric motor) mounted on the swing bracket, a connecting shaft connected to the output end of the swing drive component, and a swing arm with one end linked to the swing drive component via the connecting shaft and the other end fixedly connected to the waste collection box. During operation, after the waste cutting mechanism completes the cutting of a certain amount of waste, the control center triggers the swing drive component to move. The swing drive component drives the swing arm to swing back and forth via the connecting shaft, thereby driving the waste collection box to shake synchronously, so that the cut waste accumulated in the box is evenly distributed.

[0032] The beneficial effects of this utility model are as follows: Using a frame as the installation base, it integrates multiple mechanisms such as punching, hot pressing, punching, and transfer, as well as staggered transfer, stacking, and unloading components. Through the division of labor and precise guidance and positioning of multiple moving mechanisms, coupled with sensor feedback and automated control, it achieves continuous operation of the entire process of nitrocellulose inner caps, from roll punching, quantitative stacking, hot pressing, precise punching to automated unloading. Its beneficial effects include significantly improving the degree of production automation and reducing manual intervention. Through the coordinated positioning of the punching components and spring-loaded suction cups, the precise coordination of multiple sets of gripping / transferring components, and the orderly connection of various mechanisms, it ensures product size consistency and processing accuracy, avoiding offset and damage during sheet material transfer. Simultaneously, the clearly defined transfer mechanism and multi-station synchronous handling design shorten the operation cycle, improve production efficiency and product qualification rate, adapt to the processing needs of nitrocellulose materials, and achieve automated waste collection and treatment, ensuring a clean production environment and operational safety.

The transfer mechanism transfers the sheet material on the punching worktable 7 to the hot pressing forming mechanism 3 for hot pressing, and then transfers the hot-pressed sheet material to the punching mechanism 4 for punching.

[0046] With frame 1 as the mounting base, a punching mechanism 2, a hot pressing forming mechanism 3, a punching mechanism 4, and a transfer mechanism are integrated on it.

[0049] The frame 1 is equipped with a movable guide post 11. The punching assembly 6 and the punching worktable 7 are mounted on the movable guide post 11. The punching worktable 7 includes a punching plate 12 fixed on the movable guide post 11 and a spring buffer suction cup 14 located below the punching plate 12. The punching plate 12 has a circular hole 15. The spring buffer suction cup 14 includes an elastic drive member 16 and a positioning block 17 mounted on the elastic drive member 16. The positioning block 17 is accommodated in the circular hole 15. External coil material is fed to the punching assembly. On plate 12, when the punching drive 5 drives the punching assembly 6 to move downward along the guide post to approach the punching plate 12, the positioning block 17 is compressed by the elastic drive 16 and together with the punching assembly 6 punches the outer coil material placed on the punching plate 12 to form a sheet. When the punching drive 5 drives the punching assembly 6 to move upward away from the punching plate 12, the elastic drive 16 is reset, and the positioning block 17 pushes the sheet material up onto the reference surface of the punching plate 12 to wait for it to be transported to the next station.

[0050] The frame 1 is equipped with a movable guide post 11. The punching assembly 6 and the punching worktable 7 are both mounted on the movable guide post 11. The punching worktable 7 includes a punching plate 12 fixed on the movable guide post 11 and a spring buffer suction cup 14 located below it. The punching plate 12 has a circular hole 15. The spring buffer suction cup 14 is composed of an elastic drive member 16 and a positioning block 17 disposed thereon. The positioning block 17 is housed in the circular hole 15. After the external coil material is fed to the punching plate 12, when the punching drive member 5 drives the punching assembly 6 to move downward along the movable guide post 11 and approach the punching plate 12, the positioning block 17 is compressed by the elastic drive member 16 and works with the punching assembly 6 to feed the coil material. When the punching assembly 6 moves upward away from the punching plate 12, the elastic drive component 16 resets, and the positioning block 17 pushes the sheet material up to the reference surface of the punching plate 12 for transport to the next station. This structure ensures the motion guidance accuracy of the punching assembly 6 and the worktable through the moving guide post 11.

Within the sheet material limiting block of the second material interleaving transfer station 28; this structure achieves quantitative stacking of sheet materials through the stacking mechanism 25, and the double transfer stations of the interleaving transfer mechanism 24 and the transfer moving parts 29 work together to achieve alternating transfer of stacked sheet materials, avoiding mutual waiting between punching and subsequent transfer operations, ensuring processing continuity. At the same time, the precise cooperation between the sheet material limiting block and the lifting and moving mechanism prevents the stacked sheet materials from shifting or scattering, improves the stability and transfer efficiency of sheet material transfer, and lays the foundation for subsequent automated processing.

The vacuum generator starts to generate negative pressure, and the suction cup tightly grips the sheet material. Then, the explosion-proof cylinder 42 resets and drives the sheet material to rise. The second driving component 38 drives the slicing transport unit to move along the slicing transport guide rail 36 to the stacking position of the first material cross-transfer platform 27 of the cross-transfer mechanism 24. After arriving, the vacuum generator of the explosion-proof cylinder 42 stops working and releases the sheet material, placing the sheet material on the first material cross-transfer platform 27.

[0057] During operation, after the spring-loaded suction cup 14 lifts the sheet material, the control center sends a suction command to the stacking mechanism 25. The second drive unit 38 drives the slicing transport unit to move along the slicing transport guide rail 36 to directly above the punching position of the punching worktable 7. The explosion-proof cylinder 42 drives the vacuum suction cup to move downwards until it is in contact with the upper surface of the sheet material. The vacuum generator starts to generate negative pressure, causing the suction cup to firmly hold the sheet material. Subsequently, the explosion-proof cylinder 42 resets, causing the sheet material to rise. The second drive unit 38 continues to drive the slicing transport unit to move along the guide rail to the stacking position of the first material cross-transfer platform 27 of the cross-transfer mechanism 24. Upon arrival... The vacuum generator stops working and releases the sheet material, which is then placed on the transfer platform. This structure adapts to the safety processing requirements of nitrocellulose materials through the explosion-proof cylinder 42.
