Description

Technical Field

[0001] This invention belongs to the field of sponge molding technology, specifically a biological sponge roller press. Background Technology

[0002] Bio-sponges are man-made porous materials, typically made from materials such as gelatin, thrombin, or polyurethane. Unlike natural sponges, bio-sponges are synthetically produced bio-like materials with clearly defined biocompatibility and functional designs. A key process in the production of bio-sponge sheets is the rolling process to extrude the sheets to a specified thickness. This ensures that each sheet has a uniform and precise thickness, which is crucial for subsequent packaging, use, and dosage consistency when used as a medical product.

[0003] Patent CN223131196U discloses a sponge molding machine with convenient feeding, including a gantry frame, a sponge molding assembly for sponge molding, and feeding and unloading assemblies located on both sides of the gantry frame. The feeding and unloading assemblies use the same components. The patent uses a first motor to drive a drive shaft to rotate. The drive shaft drives a first bevel gear to push a second bevel gear and a movable lead screw to rotate synchronously. The movable lead screw pushes a movable block and a sponge molding roller to move, causing the sponge molding roller to move along the central axis of the chute. The distance between the sponge molding roller and the support roller can be adjusted. When the sponge block is between the sponge molding roller and the support roller, the second motor drives the sponge molding roller to rotate. The sponge molding roller applies thrust to the sponge block, and the sponge is rolled and squeezed by the sponge molding roller and the support roller for sponge molding.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] When rolling sponge sheets, they are first placed on a conveyor belt and transported between the sponge forming roller and the support roller, where they are pressed to a specified thickness through rolling and extrusion. However, on large-scale production lines, the number of sponge sheets to be rolled is large and they are often piled up in a disordered state. Rolling requires the sponge sheets to be laid flat and not overlapping, which requires workers to manually arrange them frequently, resulting in high labor intensity. If a robotic arm is used in conjunction with visual inspection to replace manual labor, the disordered accumulation and overlapping of the sponge sheets will make visual recognition difficult, increase the risk of grasping errors, and affect the efficiency of flattening. In addition, in order to form a smooth cycle with the next process, the rolled sponge sheets often need to be transported in fixed batches. However, the disordered feeding of the sponge sheets will also make the rolling process disordered, making it difficult to control the number of output batches, thus affecting the efficiency of continuous production.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The bio-sponge roller press of this invention utilizes a synchronous roller pressing auxiliary component to automatically separate disordered piled-up sponge sheets under the continuous operation of the conveyor rollers. These sheets are then laid flat and fed one by one into the feeding channel for smooth roller pressing. This eliminates the need for frequent manual sorting, significantly reducing labor intensity. Furthermore, compared to using a robotic arm for grasping and laying, this method fundamentally avoids visual recognition difficulties and grasping errors caused by disordered pile-up and overlapping of sponge sheets, resulting in higher laying efficiency. It also allows for precise control of the number of sponge sheets rolled in a single operation. After rolling, all sponge sheets enter the next process synchronously with a uniform orientation, achieving stable batch conveying. This not only creates a smooth production rhythm with the next process but also improves the overall continuous production efficiency of sponge sheets.

[0025] 2. The biological sponge roller press of the present invention utilizes an anti-squeezing component. After the sponge sheets enter the feeding channel, even if the sponge sheets squeeze each other, they will not bounce or stand up due to the limiting plate, pressure plate one, and pressure plate two. This further ensures that the sponge sheets remain flat in the feeding channel and can be rolled normally.

[0026] 3. The biological sponge roller press of the present invention utilizes an anti-jamming component, which, with the cooperation of a transverse rod and a deflection block, allows the sponge sheet that cannot smoothly enter the feeding channel due to being upright or abutting against the limiting plate to continuously move, change its orientation and deviate from its original path, until the sponge sheet can smoothly enter the feeding channel, further ensuring the smooth progress of the feeding work and preventing jamming.

[0050] Specifically, in existing technologies, when rolling sponge sheets, the sheets are first placed on a conveyor belt and transported between the sponge forming roller and the support roller, where they are pressed to a specified thickness through rolling and extrusion. However, on large-scale production lines, the number of sponge sheets to be rolled is large and they are often piled up in a disordered manner. Rolling requires the sponge sheets to be laid flat and not overlapping, which requires workers to manually arrange them frequently, resulting in high labor intensity. If a robotic arm is used in conjunction with visual inspection to replace manual labor, the disordered accumulation and overlapping of the sponge sheets will make visual recognition difficult, increase the risk of grasping errors, and affect the efficiency of flattening. In addition, in order to form a smooth rhythm with the next process, the rolled sponge sheets often need to be transported in batches in fixed quantities. However, the disordered feeding of the sponge sheets will also make the rolling process disordered, making it difficult to control the number of output batches, thus affecting the efficiency of continuous production.

[0051] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0052] This solution is applied to rectangular sponge sheets of the same specifications in the same batch, where the length and width of the sponge sheet are both greater than its thickness. Such sponge sheets are quite common.

[0053] First, the space between two adjacent limiting plates 25 is used as the feeding channel. Based on the width of the sponge sheet, cylinder 2 19 drives one of the limiting plates 25 to slide on the fixed rod 8. Through the transmission of connecting rod 1 20 and connecting rod 2 21, multiple limiting plates 25 can slide simultaneously, and the distance between adjacent limiting plates 25 changes, thus adjusting the width of the feeding channel. This width is greater than the width of one sponge sheet, less than the length of one sponge sheet and the width of two sponge sheets, and can be adjusted arbitrarily within this range. Then, motor 6 38 drives threaded rod 4 39 to rotate, causing baffle 1 3 to rise and fall. This adjusts the vertical distance between the bottom of baffle 1 3 and the upper edge of the conveying roller 7, ensuring this distance is equal to the thickness of the sponge sheet.

[0054] After completing the above adjustment operations, the disorderly stacked sponge sheets are uniformly placed on the conveyor roller 7, with the sponge sheets positioned between the barriers formed by baffle 3, width adjustment plate 4, baffle 5, and baffle 6. The conveyor roller 7 then transports the sponge sheets. Since only flat sponge sheets can pass through the bottom of baffle 3, upright or stacked sponge sheets will be blocked. Furthermore, because the width of the feeding channel is within the aforementioned range, the length direction of the sponge sheets entering the feeding channel is the same as the conveying direction, and the sponge sheets cannot enter the feeding channel side-by-side. After the sponge sheet moves with the conveyor roller 7 to below the upper pressure roller 17, the motor 742 drives the upper pressure roller 17 to rotate. Furthermore, according to the required thickness of the sponge sheet, the hydraulic cylinder 14 drives the connecting plate 16 to rise and fall, adjusting the distance between the upper pressure roller 17 and the lower pressure roller 18. This allows the upper and lower pressure rollers to press the sponge sheet to the specified thickness. Thus, with the continuous operation of the conveyor roller 7, the disorderly piled sponge sheets are automatically separated and placed flat, entering the feeding channel one by one for smooth rolling. This eliminates the need for frequent manual sorting, significantly reducing labor intensity. Moreover, compared to using a robotic arm for gripping and flattening, this method fundamentally avoids visual recognition difficulties and gripping errors caused by disorderly piled-up and overlapping sponge sheets, resulting in higher flattening efficiency.

[0055] Furthermore, when the rolled sponge sheets need to be transported to the next process in fixed batches, firstly, the frame 1 is connected to the next process. Then, according to the number of sponge sheets to be transported in each batch, the motor 37 drives the threaded rod 36 to rotate, causing the width adjustment plate 4 to move laterally on the threaded rod 36 and the slide bar 35. Since the sponge sheets are located on one side of the width adjustment plate 4, the number of available feeding channels can be controlled by adjusting the position of the width adjustment plate 4 so that the width adjustment plate 4 is aligned with the side limit plate 25. When the number of available feeding channels is the same as the number of sponge sheets to be transported in each batch, the sponge sheets only enter the available feeding channels. Moreover, when the width adjustment plate 4 moves, the baffle 2 5 will remain in contact with the surface of the width adjustment plate 4 under the action of the spring 41, and the distance between the bottom of the width adjustment plate 4 and the conveying roller 7 is small, so the sponge sheets will not pass through the bottom of the width adjustment plate 4. After the sponge sheets enter the feeding channel, they are blocked by baffle 4 10. When all sponge sheets in the feeding channels are blocked by baffle 4 10, motor 1 9 drives baffle 4 10 to rotate, so that baffle 4 10 no longer blocks the sponge sheets. Multiple sponge sheets then move side-by-side to the upper pressure roller 17 and lower pressure roller 18 for simultaneous rolling. After the sponge sheets move out of the feeding channel side-by-side, baffle 4 10 quickly resets, blocking subsequent sponge sheets. A fixed number of sponge sheets will then synchronously enter the next process after rolling. By repeating the above operation, the number of sponge sheets rolled in a single cycle can be precisely controlled. After rolling, all sponge sheets enter the next process synchronously with the same orientation, thus achieving stable batch conveying. This not only creates a smooth production rhythm with the next process but also improves the overall continuous production efficiency of sponge sheets.

[0056] In this embodiment, as Figure 5 As shown, it also includes an anti-crushing component;

[0057] The anti-pinch assembly includes a pressure plate 23 and a pressure plate 24 that are slidably connected to both sides of the limiting plate 25. The adjacent pressure plate 23 and pressure plate 24 are inserted and slidably connected. Guide rail plates 11 are fixedly connected to both sides of the upper end of the frame 1. A lifting plate 13 is slidably connected to one side of the two guide rail plates 11. A connecting rod 22 is fixedly connected to one side of the upper end of the pressure plate 23. The upper end of the connecting rod 22 is slidably connected to the lifting plate 13. A cylinder 12 is fixedly connected to one side of the upper end of one guide rail plate 11. The piston end of the cylinder 12 is fixedly connected to one side of the upper surface of the lifting plate 13.

[0058] Specifically, in the above embodiments, in order to control the number of sponge sheets in a single roll pressing, it is necessary to first use baffle 410 to block the sponge sheets. Then the sponge sheets in the feeding channel will squeeze each other. Since the sponge sheets are elastic, they may deform due to the squeezing, and thus pop out of the feeding channel or stand up due to the squeezing, making it impossible to perform the roll pressing operation normally.

[0059] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0060] Pressure plates 23 and 24 cover the top of the feeding channel. When the limiting plate 25 moves, the connecting rod 22 also slides on the lifting plate 13, and pressure plates 23 and 24 slide relative to each other to accommodate the width of the feeding channel. Subsequently, cylinder 12 drives the lifting plate 13 to descend, adjusting the distance between pressure plate 23 and the upper edge of the conveying roller 7, making this distance equal to the thickness of the sponge sheet. After the sponge sheet enters the feeding channel, even if the sponge sheets are squeezed against each other, they will not bounce or stand up due to the limiting plate 25, pressure plate 23, and pressure plate 24, thus further ensuring that the sponge sheet remains flat in the feeding channel and can be rolled normally.

[0061] In this embodiment, as Figure 3 , Figures 5-9 As shown, it also includes anti-jamming components;

[0062] The anti-jamming component includes a cylinder 31 that is slidably connected to one side of the baffle 3. A transverse rod 32 is fixedly connected to the piston end of the cylinder 31. The transverse rod 32 is in contact with one side surface of the baffle 3. A push plate 26 is slidably connected to one side of the inner cavity of the limiting plate 25. A deflection block 30 is rotatably provided at one end of the push plate 26.

[0063] A threaded rod 28 is threadedly connected to one side of the push plate 26. One end of the threaded rod 28 is rotatably set on one side of the inner cavity of the limiting plate 25. A motor 27 is fixedly connected to one side of the inner cavity of the limiting plate 25. The output end of the motor 27 is fixedly connected to one end of the threaded rod 28. A motor 39 is fixedly connected to one end of the push plate 26. The output end of the motor 39 is fixedly connected to one end of the deflection block 30.

[0064] One side of cylinder 31 is threadedly connected to threaded rod 2 34. Both ends of threaded rod 2 34 are rotatably mounted on baffle 1 3. One side of baffle 1 3 is fixedly connected to motor 4 33. The output end of motor 4 33 is fixedly connected to one end of threaded rod 2 34.

[0065] Specifically, in the above embodiments, although the conveying roller 7 can deliver the sponge sheets to the feeding channel, the length direction of the sponge sheets must be consistent with the conveying direction. In actual operation, some sponge sheets may fail to enter the feeding channel smoothly due to incorrect orientation or their ends abutting against the limiting plate 25. In addition, if the sponge sheets are in an upright state, the friction of the conveying roller 7 and the cooperation of the baffle 3 alone are often insufficient to effectively tilt them, which will also lead to feeding interruption.

[0066] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0067] During the rotation of the conveyor roller 7, motor 27 drives the threaded rod 28 to rotate, causing the push plate 26 to move back and forth, extending out of the limiting plate 25 and then retracting. If a sponge sheet abuts against the end of the limiting plate 25, the deflector block 30 will push it away. Then, motor 39 drives the deflector block 30 to rotate, using the pushing of the deflector block 30 to disengage the sponge sheet from its original path, preventing it from abutting against the limiting plate 25 again. At the same time, it can also change the orientation of the sponge sheet until it can smoothly enter the feeding channel. The sponge sheet with the correct orientation and path will not contact the deflector block 30, so it will not interfere with the sponge sheet that can normally enter the feeding channel. Similarly, motor 33 drives threaded rod 34 to rotate, causing cylinder 31 and transverse rod 32 to slide laterally back and forth. Transverse rod 32 only moves between usable feeding channels. Since the lower end of transverse rod 32 is flush with the lower end of baffle 3, when the sponge sheet stands up, transverse rod 32 pushes it until it tilts. Furthermore, to prevent transverse rod 32 from pushing the standing sponge sheet towards the angle formed by frame 1 and baffle 3, thus preventing the sponge sheet from tilting properly, a vision inspection component can be installed on one side of frame 1 before transverse rod 32 moves laterally. This vision inspection component is existing technology and can be easily installed by those skilled in the art; further details are omitted here. The vision inspection component determines whether there are sponge sheets at the two corners of frame 1. If so, transverse rod 32 rises under the action of cylinder 31, then moves laterally to one corner, and then descends, pushing the sponge sheet away from the corner until it can tilt normally. With the cooperation of the transverse rod 32 and the deflection block 30, the sponge sheet that cannot smoothly enter the feeding channel due to being upright or abutting against the limit plate 25 can be continuously moved, changing its orientation and causing it to deviate from its original path until the sponge sheet can smoothly enter the feeding channel, further ensuring the smooth progress of the feeding work and preventing jamming.

[0068] Working Principle: First, the space between two adjacent limiting plates 25 serves as the feeding channel. Based on the width of the sponge sheet, cylinder 2 19 drives one of the limiting plates 25 to slide on the fixed rod 8. Through the transmission of connecting rod 1 20 and connecting rod 2 21, multiple limiting plates 25 slide simultaneously, and the distance between adjacent limiting plates 25 changes, thus adjusting the width of the feeding channel. This width is greater than the width of one sponge sheet, less than the length of one sponge sheet, and less than the width of two sponge sheets. The width of the feeding channel can be adjusted arbitrarily within this range. Then, motor 6 38 drives threaded rod 4 39 to rotate, causing baffle 1 3 to rise and fall. This adjusts the vertical distance between the bottom of baffle 1 3 and the upper edge of the conveyor roller 7, ensuring this distance is equal to the thickness of the sponge sheet. After completing the above adjustment operations, the disorderly stacked sponge sheets are uniformly placed on the conveyor roller 7, with the sponge sheets positioned between the barriers formed by baffle 1 3, width adjustment plate 4, baffle 2 5, and baffle 3 6. Then, the sponge sheets are conveyed using the conveyor roller 7. Since only flat sponge sheets can pass through the bottom of the baffle 3, upright or stacked sponge sheets will be blocked. Furthermore, because the width of the feeding channel is within the aforementioned range, the length direction of the sponge sheets entering the feeding channel is the same as the conveying direction, and the sponge sheets cannot enter the feeding channel side-by-side. When the sponge sheets move with the conveyor roller 7 to below the upper pressure roller 17, the motor 742 drives the upper pressure roller 17 to rotate. Based on the required thickness of the sponge sheets, the hydraulic cylinder 14 drives the connecting plate 16 to rise and fall, adjusting the distance between the upper pressure roller 17 and the lower pressure roller 18. The upper pressure roller 17 and the lower pressure roller 18 can then roll the sponge sheets to the specified thickness. Thus, with the continuous operation of the conveyor roller 7, the disorderly piled sponge sheets are automatically separated and enter the feeding channel one by one in a flat state for smooth rolling. This eliminates the need for frequent manual sorting, significantly reducing labor intensity. Furthermore, compared to using a robotic arm for grasping and laying flat, this method fundamentally avoids the visual recognition difficulties and grasping errors caused by the disorderly stacking and mutual obstruction of sponge sheets, resulting in higher laying efficiency. Additionally, when the rolled sponge sheets need to be transported to the next process in fixed batches... First, connect the frame 1 to the next process. Then, according to the number of sponge sheets to be conveyed in each batch, drive the threaded rod 36 to rotate via motor 5 37, causing the width adjustment plate 4 to move laterally on the threaded rod 36 and slide bar 35. Since the sponge sheets are located on one side of the width adjustment plate 4, the number of available feeding channels can be controlled by adjusting the position of the width adjustment plate 4 so that it is aligned with the side limit plate 25. When the number of available feeding channels is the same as the number of sponge sheets to be conveyed in each batch, the sponge sheets will only enter the available feeding channels. Furthermore, when the width adjustment plate 4 moves, the baffle 2 5 will remain in contact with the surface of the width adjustment plate 4 under the action of spring 41, and the distance between the bottom of the width adjustment plate 4 and the conveying roller 7 is small, so the sponge sheets will not pass through the bottom of the width adjustment plate 4.After the sponge sheets enter the feeding channel, they are blocked by baffle 4 10. When all sponge sheets in the feeding channels are blocked by baffle 4 10, motor 1 9 drives baffle 4 10 to rotate, so that baffle 4 10 no longer blocks the sponge sheets. Multiple sponge sheets then move side-by-side to the upper pressure roller 17 and lower pressure roller 18 for simultaneous rolling. After the sponge sheets move out of the feeding channel side-by-side, baffle 4 10 quickly resets, blocking subsequent sponge sheets. A fixed number of sponge sheets will then synchronously enter the next process after rolling. By repeating the above operation, the number of sponge sheets rolled in a single cycle can be precisely controlled. After rolling, all sponge sheets enter the next process synchronously with the same orientation, thus achieving stable batch conveying. This not only creates a smooth production rhythm with the next process but also improves the overall continuous production efficiency of sponge sheets. Pressure plates 23 and 24 cover the top of the feeding channel. When the limiting plate 25 moves, the connecting rod 22 also slides on the lifting plate 13, and pressure plates 23 and 24 slide relative to each other to accommodate the width of the feeding channel. Subsequently, cylinder 12 drives the lifting plate 13 to descend, adjusting the distance between pressure plate 23 and the upper edge of the conveying roller 7, making this distance equal to the thickness of the sponge sheet. After the sponge sheet enters the feeding channel, even if the sponge sheets are squeezed against each other, they will not bounce or stand up due to the limiting plate 25, pressure plate 23, and pressure plate 24, thus further ensuring that the sponge sheet remains flat in the feeding channel and can be rolled normally. During the rotation of the conveyor roller 7, motor 27 drives the threaded rod 28 to rotate, causing the push plate 26 to move back and forth, extending out of the limiting plate 25 and then retracting. If a sponge sheet abuts against the end of the limiting plate 25, the deflector block 30 will push it away. Then, motor 39 drives the deflector block 30 to rotate, using the pushing of the deflector block 30 to disengage the sponge sheet from its original path, preventing it from abutting against the limiting plate 25 again. At the same time, it can also change the orientation of the sponge sheet until it can smoothly enter the feeding channel. The sponge sheet with the correct orientation and path will not contact the deflector block 30, so it will not interfere with the sponge sheet that can normally enter the feeding channel. Similarly, motor 33 drives threaded rod 34 to rotate, causing cylinder 31 and transverse rod 32 to slide laterally back and forth. Transverse rod 32 only moves between usable feeding channels. Since the lower end of transverse rod 32 is flush with the lower end of baffle 3, when the sponge sheet stands up, transverse rod 32 will push it until it tilts. Furthermore, to prevent transverse rod 32 from pushing the upright sponge sheet towards the angle formed by frame 1 and baffle 3, thus preventing the sponge sheet from tilting properly, a vision inspection component can be installed on one side of frame 1 before transverse rod 32 moves laterally. The vision inspection component is existing technology and can be easily installed by those skilled in the art; further details are omitted here.The visual inspection component determines whether there are sponge sheets at the two corners of the frame 1. If so, the transverse rod 32 will rise under the action of the cylinder 31, then move laterally to one corner, and then descend to push the sponge sheet away from the corner until it can be tilted normally. Thus, with the cooperation of the transverse rod 32 and the deflection block 30, the sponge sheet that cannot smoothly enter the feeding channel due to being upright or abutting against the limit plate 25 is continuously moved, changing its orientation and causing it to deviate from its original path until the sponge sheet can smoothly enter the feeding channel, further ensuring the smooth progress of the feeding operation and preventing jamming.
