Description

Technical Field

[0001] This utility model relates to the technical field of seafood processing equipment, specifically a multi-functional kelp cutting machine. Background Technology

[0002] In existing kelp processing, cutting is an essential step. Depending on the final product requirements, kelp generally needs to be shredded from the thinner areas on both sides, while the thicker, central section needs to be sliced. This facilitates further slicing or rolling, meeting various usage needs.

[0003] Existing kelp cutting machines have relatively limited functions, and most can only perform full shredding. The relatively thicker areas in the middle still need to be sliced ​​manually, which is time-consuming and labor-intensive, and restricts the efficiency of large-scale production and processing. Summary of the Invention

It can process different regions of kelp, which are thicker in the middle and thinner on both sides, in a single operation, enabling kelp to be sliced ​​and shredded in different areas simultaneously, thus significantly improving the efficiency of kelp cutting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The multi-functional kelp cutting machine includes a transmission mechanism, a conveying platform, a shredding device, and a slicing device. A horizontal conveyor belt is installed on the conveying platform, and the slicing device and the shredding device are sequentially mounted above the conveying platform behind the horizontal conveyor belt.

[0006] The slicing device includes a slicing drive roller shaft and a first vertical cutting blade. The first vertical cutting blade is sleeved in the middle of the slicing drive roller shaft and is spaced apart. The two ends of the slicing drive roller shaft are connected by a first bearing seat fixed to both sides of the conveying platform, and one end of the roller shaft extends out of the first bearing seat and is connected to the transmission mechanism through gear and chain transmission.

[0007] The slicing device is located at the rear end of the horizontal conveyor belt. It is rotatably connected to the filament cutting drive roller shaft via the second bearing seat. The two ends of the filament cutting drive roller shaft are respectively rotatably connected to the second vertical filament cutting blade assembly.

[0008] Preferably, the conveying platform has a first driving roller and a driven roller at its front and rear ends, respectively, and a horizontal conveyor belt is connected to the outside of the first driving roller and the driven roller.

[0009] The conveyor platform located at the rear end of the horizontal conveyor belt has side vertical support frames on both sides.

[0010] A first longitudinal partition is provided between the rear sides of both ends of the first vertical cutting blade of the slicing device and the inner sides of the two sets of second vertical filament cutting blades of the filament cutting device. Each longitudinal partition has a limiting groove that engages with a limiting shaft at both the front and rear.

[0011] Multiple sets of limiting shafts are connected between the two side vertical support frames. The limiting shafts can pass laterally through the limiting slots on the two first longitudinal partitions to limit and fix the first longitudinal partitions above the horizontal conveyor belt; the distance between the first longitudinal partitions and the horizontal conveyor belt is less than 5mm.

[0012] Preferably, a pressing blade assembly bracket that matches the second vertical filament cutting blade assembly is also connected above the horizontal conveyor belt. The front part of the pressing blade assembly bracket is connected by a third transverse support shaft connected between the two side vertical support frames. The pressing blade assembly bracket is located below the second vertical filament cutting blade assembly and is staggered with the second vertical filament cutting blade assembly to achieve overall shredding of the relatively thin kelp on both sides.

[0013] Meanwhile, both sides of the downward-pressing blade assembly bracket are supported above the conveying platform by matching first support frames, which are used to laterally limit and fix the second vertical filament cutting blade assembly.

[0014] Preferably, the downward blade assembly bracket is composed of multiple V-shaped brackets, with the front end of the V-shaped bracket fixed to the third transverse support shaft and its rear end extending out of the rear end of the horizontal conveyor belt.

[0015] The bottom support at the rear end of the conveyor platform is also fixedly connected to a material feeding divider plate that matches the horizontal conveyor belt, and the material feeding divider plate is provided with two sets of second longitudinal dividers that match the front and rear positions of the first longitudinal divider plate.

[0016] Preferably, a first transverse partition is provided between the two first longitudinal partitions and is perpendicular to them.

[0017] A second crossbar is also connected between the two side vertical support frames. The upper part of the first horizontal partition is fixedly connected to the second crossbar, and the distance between the first horizontal partition and the horizontal conveyor belt is 1cm-10cm.

[0018] Preferably, the horizontal conveyor belt is a frosted conveyor belt, and multiple sets of longitudinal cutting friction grooves matching the first vertical cutting blade are provided in the middle of the frosted conveyor belt, for cutting the thick part of the kelp in the middle into long strips;

[0019] The spacing between the first vertical cutting blades is equal to the width of the kelp slice to be cut.

[0020] Preferably, a protective cover matching the top of the shredding device and the slicing device is respectively hinged between the two side vertical support frames via a fourth support crossbar and a fifth support crossbar.

[0021] Preferably, the transmission mechanism includes a motor and a gear and chain drive.

[0022] The motor is mounted on the bottom support of the conveyor platform, and its output shaft is connected to two coaxial gears: a first driving gear and a second driving gear.

[0023] A coaxial double gear is sleeved at one end of the slicing drive roller shaft after passing through the first bearing seat: a third drive gear and a fourth drive gear. On the same side, at one end of the filament cutting drive roller shaft, a fifth drive gear is sleeved in the same plane as the fourth drive gear. The fifth drive gear and the fourth drive gear are connected by a chain drive.

[0024] A sixth transmission gear is sleeved on the outer end of the first drive roller shaft on the same side, and the sixth transmission gear is connected to the first drive gear on the inner side through chain drive.

[0025] On the same side, on the conveying platform located in front of the slice drive roller shaft, there are also coaxial double gears: the seventh drive gear and the eighth drive gear. The seventh drive gear located on the inner side meshes with the third drive gear, and the eighth drive gear located on the outer side drives the chain with the second drive gear on the outer side.

[0026] Ultimately, the motor rotates, simultaneously driving the slicing transmission roller shaft and the filament cutting transmission roller shaft to rotate synchronously in the opposite direction to the first active roller shaft.

[0027] The multifunctional kelp cutter provided by this utility model has the following beneficial effects:

[0028] (1) The multifunctional kelp cutting machine of this utility model has a simple and ingenious structure. Through the ingenious layout design of the cutting device on the platform, the slicing device and the shredding device work together. It can perform one-time partitioning processing on the different regions of kelp that are thicker in the middle and thinner on both sides, so that the device can perform partitioning slicing and shredding processing on a piece of kelp at the same time without the need for subsequent equipment operation. This achieves precise cutting of the differentiated regions of kelp, effectively improves cutting efficiency, and meets the actual diversified processing needs of kelp.

[0029] (2) The multifunctional kelp cutting machine of this utility model has strong transmission synchronization. Through the motor-driven gear chain transmission, the conveyor belt, slicing device and shredding device are driven to rotate synchronously, ensuring that the conveyor belt speed matches the cutting blade speed, realizing precise cutting of different areas of kelp, and significantly improving cutting accuracy and stability.

[0030] Using a single power source and a specially designed transmission device to work together, the device drives multiple components to move synchronously. The device has a simplified structure, a small footprint, and low power loss, ensuring that the equipment can continuously and effectively cut sections to meet the actual needs of kelp cutting and processing.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Please see Figures 1-4 This utility model provides a technical solution:

[0039] The multifunctional kelp cutting machine provided by this utility model includes a transmission mechanism, a conveying platform, a shredding device, and a slicing device. The front and rear ends of the conveying platform are respectively provided with a first active roller shaft 2 and a driven roller shaft 3. A horizontal conveyor belt 1 is connected to the outside of the first active roller shaft 2 and the driven roller shaft 3. Through the transmission mechanism at the outer end of the first active roller shaft 2, the first active roller shaft 2 can be rotated, thereby driving the horizontal conveyor belt 1 to rotate, so as to realize the conveying of kelp.

[0040] like Figure 2 As shown, a slicing device and a shredding device are sequentially mounted above the conveyor platform behind the horizontal conveyor belt 1. The slicing device includes a slicing drive roller 4 and a first vertical cutting blade 5. The first vertical cutting blade 5 is sleeved on the middle of the slicing drive roller 4 and spaced apart, and is used to slice the relatively thicker area in the middle of the kelp into slices of a predetermined width. A first longitudinal partition 11 is provided between the rear sides of both ends of the first vertical cutting blade 5 of the slicing device and the inner sides of the two sets of second vertical filament cutting blades 9 of the shredding device, respectively, to isolate the slicing area and the shredding area, ensure the orderly transition of kelp slices and kelp filaments, prevent interference, and ensure cutting accuracy and equipment safety. Both the front and rear of the longitudinal partition are provided with limiting slots that engage with the limiting shafts 12. Multiple sets of limiting shafts 12 are also connected between the two side vertical support frames 10. The limiting shafts 12 can pass laterally through the limiting slots on the two first longitudinal partitions 11, limiting and fixing the first longitudinal partitions 11 above the horizontal conveyor belt 1. The distance between the first longitudinal partitions 11 and the horizontal conveyor belt 1 is less than 5mm, ensuring effective segmentation of the kelp in the middle area and ensuring that kelp of different thicknesses enters the corresponding cutting device for effective cutting after cutting. The two ends of the slicing drive roller shaft 4 are connected by first bearing seats 6 fixed to both sides of the conveyor platform, and one end extends out of the first bearing seat 6 and is connected to the transmission mechanism via gears and chains.

[0041] like Figure 2As shown, the slicing device is located on the conveying platform at the rear end of the horizontal conveyor belt 1, and includes a filament cutting drive roller shaft 8 rotatably connected to a second bearing seat 7. The two ends of the filament cutting drive roller shaft 8 are respectively rotatably connected to a second vertical filament cutting blade assembly 9. On both sides of the conveyor platform at the rear end of the horizontal conveyor belt 1, and in front of the first bearing seat 6 and the second bearing seat 7 on the same side, there are side vertical support frames 10. Above the horizontal conveyor belt 1, there is also a pressing blade assembly bracket 15 that matches the second vertical filament cutting blade assembly 9. The front part of the pressing blade assembly bracket 15 is connected by a third transverse support shaft 16 connected between the two side vertical support frames 10. The pressing blade assembly bracket 15 is located below the second vertical filament cutting blade assembly 9 and is staggered with the second vertical filament cutting blade assembly 9 to achieve overall precise and effective shredding of the relatively thin kelp on both sides. At the same time, both sides of the pressing blade assembly bracket 15 are supported above the conveyor platform by matching first support frames to laterally limit and fix the second vertical filament cutting blade assembly 9. This structure can ensure the stability of the shredded kelp raw material and achieve precise and effective shredding. The downward blade assembly bracket 15 is composed of multiple V-shaped brackets. The front end of the V-shaped bracket is fixed to the third transverse support shaft 16, and its rear end extends out of the horizontal conveyor belt 1. This structural design allows the seaweed shreds to be transported quickly and effectively after cutting, and it is not easy to cause compression.

[0042] Located at the rear end of the conveyor platform, an inclined feeding divider plate, matching the horizontal conveyor belt 1, is fixedly connected via a second support frame. This serves as a transition between the horizontal conveyor belt 1 and the collection device, allowing the cut kelp slices or kelp shreds to automatically slide into their corresponding collection containers under gravity, preventing accumulation at the end of the conveyor belt and saving labor in handling. The feeding divider plate is equipped with two sets of second longitudinal partitions, each matching the front and rear positions of the first longitudinal partition 11, used to separate the kelp slices and kelp shreds for collection, further improving the handling efficiency of the cut kelp.

[0043] like Figure 4 As shown, a first transverse partition 13 is located between two first longitudinal partitions 11 and perpendicular to them. A second crossbar 14 is also connected between two side vertical support frames 10. The upper part of the first transverse partition 13 is fixedly connected to the second crossbar 14, and the distance between the first transverse partition 13 and the horizontal conveyor belt 1 is 1cm-10cm. This is used to precisely control the movement trajectory of the cut kelp slices, allowing kelp slices of normal thickness to pass through, preventing material accumulation, and reducing abnormal vibration of the conveyor belt to enhance stability.

[0044] The horizontal conveyor belt 1 is a frosted conveyor belt, and multiple sets of longitudinal cutting friction grooves matching the first vertical cutting blades 5 are provided in the middle of the frosted conveyor belt for cutting the thicker middle part of the kelp into long strips. The spacing between the first vertical cutting blades 5 is equal to the width of the kelp strips to be cut, achieving precise and stable cutting of the middle area of ​​the kelp and preventing slippage. The end of the driven roller shaft 3 located inside the horizontal conveyor belt 1 is connected to the front end of the conveyor platform through a tensioning mechanism. Protective covers matching the top of the shredding device and the slicing device are respectively limited and hinged between the two side vertical support frames 10 by the fourth support crossbar and the fifth support crossbar.

[0045] like Figure 2 and Figure 3 As shown, the transmission mechanism includes a motor 17 and a gear chain drive. The motor 17 is mounted on the bottom support of the conveying platform, and its output shaft is connected to coaxial double gears: a first driving gear 18 and a second driving gear 19. A coaxial double gear, a third transmission gear 20 and a fourth transmission gear 21, is sleeved at the end of the slicing transmission roller shaft 4 after passing through the first bearing seat 6. A fifth transmission gear 22, located in the same plane as the fourth transmission gear 21, is sleeved at one end of the filament cutting transmission roller shaft 8. The fifth transmission gear 22 and the fourth transmission gear 21 are connected by a chain drive. A sixth transmission gear 23 is sleeved at the end of the first driving roller shaft 2 on the same side. The sixth transmission gear 23 is connected to the inner first drive gear 18 via chain drive; on the same side, on the conveying platform located in front of the slicing drive roller 4, there are also coaxial double gears: the seventh transmission gear 24 and the eighth transmission gear 25. The inner seventh transmission gear 24 meshes with the third transmission gear 20, and the outer eighth transmission gear is connected to the outer second drive gear 19 of the motor 17 via chain drive; ultimately, the rotation of the motor 17 drives the first drive roller 2 and the slicing drive roller 4 to rotate synchronously in the opposite direction with the filament cutting drive roller 8, which is more conducive to achieving precise and effective cutting of kelp and preventing slippage.

[0046] The working principle of this multifunctional kelp cutting machine is as follows:

[0047] Workers lay the entire sheet of kelp flat on the horizontal conveyor belt 1 and start the motor 17. The first drive gear 18 at the output end of the motor 17 drives the sixth transmission gear 23 at the end of the first drive roller 2 to rotate via a chain. The rotation of the first drive roller 2 drives the horizontal conveyor belt 1 to transport the kelp backward to the slicing and shredding devices. At the same time, the second drive gear 19 at the output end of the motor 17 drives the coaxial eighth transmission gear 25 and seventh transmission gear 24 to rotate synchronously in the same direction via a chain. Since the seventh transmission gear 24 meshes with the third transmission gear 20 at the end of the slicing transmission roller 4, it will drive the coaxial third transmission gear 20 and fourth transmission gear 21 on the slicing transmission roller 4 to rotate in the opposite direction. This will cause the first vertical cutting blade 5 to move in the opposite direction to the horizontal conveyor belt 1, thus effectively slicing the relatively thicker area of ​​the kelp in the middle of the horizontal conveyor belt 1. At the same time, the fourth transmission gear 21 drives the fifth transmission gear 22 on the filament cutting transmission roller shaft 8 to rotate synchronously in the same direction through the chain, which drives the second vertical filament cutting blade assembly 9 and the horizontal conveyor belt 1 to rotate in the opposite direction, so as to effectively cut the thin kelp area on both sides of the kelp.

[0048] During operation, workers can lay the entire sheet of kelp flat or roll it into a roll and place it on the front end of the horizontal conveyor belt 1. Driven by motor 17 and a gear chain, the horizontal conveyor belt 1, slicing device, and shredding device rotate synchronously. This process addresses the different characteristics of the kelp, with the thicker center and thinner sides, allowing for slicing and shredding of a single sheet of kelp in one operation. The cut kelp slices and shreds are then collected separately using a feeding separator slide and two sets of second longitudinal partitions.

[0049] This utility model discloses a multi-functional kelp cutting machine with a simple and ingenious structure. Through the synergistic effect of the slicing device and the shredding device, it integrates multi-functional cutting capabilities, enabling the slicing and shredding of a single sheet of kelp in one operation without the need for separate equipment, thus significantly improving cutting efficiency.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
