Description

Technical Field

[0001] This utility model relates to the field of kelp processing technology, and in particular to a disc-blade cutting type kelp grading and recycling device. Background Technology

[0002] Kelp is an important component of my country's marine economy, and its processing industry has developed rapidly. With the continuous expansion of kelp farming, China's kelp farming output reached 1.742 × 10⁻⁶ tons in 2024. 6 With the increasing demand for kelp processing equipment, the demand for kelp processing equipment is also growing.

[0003] The thicker parts of kelp, such as the head, have a better texture and are more expensive; other parts of the kelp are relatively thinner and cheaper. Therefore, kelp processing typically involves grading and recycling. The thicker kelp heads are sold separately without cutting them, while the thinner kelp is usually knotted. Currently, the most common method of kelp grading relies on manual sorting. Manual grading is extremely inefficient; each person can only process a small amount of kelp per hour.

[0004] In the recycling of kelp, traditional methods often involve the extensive processing of leftover kelp, resulting in the waste of a large amount of usable kelp resources. Some of this leftover kelp may not have been used initially due to irregular shapes or other reasons, but it still has significant economic value.

[0005] In addition, existing cutting tools are not effective when cutting kelp, resulting in rough cut surfaces that can easily cause secondary damage to the kelp, affecting its subsequent processing and quality. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned defects in the existing technology and propose a disc-blade cutting type kelp grading and recycling device, which can realize the grading and recycling of kelp of different thicknesses. The kelp cutting quality is high, so that kelp can be more fully utilized in various fields and the recycling rate of kelp resources is improved.

[0007] The technical solution of this utility model is: a disc-blade cutting type kelp grading and recycling device, comprising:

[0008] The lifting and cutting mechanism, located below the kelp to be graded and cut, includes several disc blades;

[0009] The advancing clamping mechanism includes a straightening part and a cutting clamping part. The straightening part is located outside the cutting clamping part and includes a clamping straightening jaw. The cutting clamping part includes several clamping jaws, which are located between two adjacent discs.

[0010] The material collection mechanism is located in several recycling hoppers, which are situated below the cutting clamping unit.

[0011] In this utility model, the lifting and cutting mechanism includes:

[0012] The cylinder is connected to the cutter shaft holder above it via a cylinder extension rod;

[0013] The cutter shaft is rotatably mounted on the cutter shaft holder, with its axis oriented along the length of the coastal zone. The cutter shaft is connected to the output shaft of the cutter shaft motor, which is mounted on the cutter shaft holder. Several disc cutters are spaced apart along the axial direction on the cutter shaft.

[0014] The cutting clamping part includes:

[0015] The output end of the lead screw motor is connected to the gripper bracket via a lead screw.

[0016] The gripper bracket is arranged along the length of the coastal belt, with one side fixedly connected to the end of the feed screw, and several gripping claws spaced apart on the side facing the lifting and cutting mechanism.

[0017] The clamping jaws are positioned so that their opening and closing ends face the lifting and cutting mechanism.

[0018] The straightening section includes two symmetrically arranged clamping and straightening jaws, while the clamping jaws of the cutting clamping section are located between the clamping and straightening jaws on both sides.

[0019] The clamping jaws / clamping and straightening jaws include:

[0020] The two clamping arms located outside the housing include an upper clamping arm and a lower clamping arm;

[0021] The two inner clamping arms located inside the housing include an upper inner clamping arm and a lower inner clamping arm. The upper inner clamping arm is located above the lower inner clamping arm. The upper inner clamping arm and the lower clamping arm are fixedly connected, and the lower inner clamping arm and the upper clamping arm are fixedly connected. The upper inner clamping arm and the lower inner clamping arm are hinged to the same rotating shaft, and the upper inner clamping arm and the lower inner clamping arm are set at an angle.

[0022] The clamping cylinder has a column head fixed to the end of its telescopic rod. The column head has a trapezoidal cross-section. The upper surface of the column head is in contact with the bottom surface of the upper inner clamping arm, and the lower surface of the column head is in contact with the top surface of the lower inner clamping arm.

[0023] The plurality of recycling hoppers are arranged along the length of the coastal zone;

[0024] The recycling hopper is bolted to the frame, which has several bolt holes. The position of the recycling hopper can be adjusted by changing the position of the bolt holes connected to it.

[0025] The beneficial effects of this utility model are:

[0026] (1) This application uses a disc cutter to cut kelp. Compared with traditional cutters, the disc cutter has a larger cutting area and a more stable cutting trajectory during the cutting process, which can cut kelp faster and more efficiently. By setting the disc cutters at intervals to work simultaneously, the cutting efficiency is greatly improved, and a large amount of kelp can be processed quickly, reducing the time and labor intensity of manual cutting.

[0027] (2) By reasonably setting the installation position and spacing of the disc cutter on the cutter shaft and cooperating with the clamping jaws, it is possible to stably cut kelp of different lengths according to actual needs. This flexibility allows the device to meet the diverse requirements of different customers for kelp length, and improves the applicability and practicality of the device.

[0028] (3) The cylinder in the lifting and cutting mechanism can drive the cutter shaft frame to move up and down through the cylinder telescopic rod, so as to realize the lifting and lowering function of the disc cutter. The cutting height can be flexibly adjusted according to the thickness of the kelp and the cutting requirements to ensure the cutting quality.

[0029] (4) By using the clamping and straightening jaws, the kelp can be stably clamped and straightened, ensuring that the kelp remains flat during the cutting process and improving the cutting accuracy; During the cutting of kelp by the disc cutter, the clamping jaws and the clamping and straightening jaws clamp the kelp, ensuring that the kelp remains straight and stable during the cutting process, thus improving the cutting stability.

[0030] (5) The device includes multiple recycling hoppers, which are located below the corresponding clamping claws. After graded cutting, kelp of different thicknesses can fall into different recycling hoppers, realizing the classified collection of cut kelp, which is convenient for subsequent processing and treatment, avoids kelp mixing, and improves production efficiency and product quality. The collection method proposed in this application is also convenient for the statistics and management of cut kelp.

[0031] (6) Compared with existing kelp grading and cutting technologies, the device described in this application reduces human intervention, reduces the impact of human factors on the cutting effect, and improves the stability and consistency of production;

[0032] In summary, this application not only ensures rapid, multi-dimensional grading and cutting of kelp, effectively meeting the market's stringent requirements for different grades of kelp products, but also enables efficient recycling of various types of surplus kelp, improving the comprehensive utilization rate of kelp, reducing production costs, effectively enhancing the overall efficiency of the kelp processing industry, and promoting the sustainable development of the kelp industry.

Detailed Implementation

[0039] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0040] Specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] like Figure 1 As shown, the disc-blade cutting type kelp grading and recycling device of this utility model includes a frame, a lifting and cutting mechanism, a pushing and clamping mechanism, and a collecting mechanism. The lifting and cutting mechanism, the pushing and clamping mechanism, and the collecting mechanism are all mounted on the frame. Because the frame structure adopts a structure that is common to those skilled in the art, therefore... Figure 1 The frame was drawn in an abbreviated manner.

[0042] The lifting and cutting mechanism is located outside the pushing and clamping mechanism, with the clamps of the pushing and clamping mechanism facing the lifting and cutting mechanism. The collecting mechanism is fixed to the frame and located below the pushing and clamping mechanism. The pushing and clamping mechanism clamps the whole piece of kelp before cutting and during the cutting process. The lifting and cutting mechanism cuts the kelp into segments. The collecting mechanism collects the segments of kelp after cutting.

[0043] The propulsion clamping mechanism includes a straightening section and a cutting clamping section. The straightening section is mainly used to straighten the whole piece of kelp to be cut, while the cutting clamping section is mainly used to clamp the kelp segments during the cutting process.

[0044] like Figure 1 and Figure 2 As shown, the straightening section includes two clamping straightening jaws 8, which are located on the outer sides of both ends of the cutting clamping section. One end of the clamping straightening jaw 8 faces the lifting cutting mechanism, and the other end is connected to the push cylinder. During the operation of the push cylinder, it can drive the clamping straightening jaw 8 to move towards or away from the lifting cutting mechanism.

[0045] When it is necessary to grade and cut the kelp separately, the cylinder is activated, simultaneously pushing the clamping and straightening jaws 8 on both sides towards the lifting and cutting mechanism until they are directly above the lifting and cutting mechanism. At this point, both ends of the kelp are placed in the clamping and straightening jaws 8 on both sides.

[0046] During this process, the position of the kelp can be manually adjusted to straighten it, and then the two ends of the kelp can be clamped by the clamping and straightening claws 8 on both sides. Alternatively, the clamping and straightening claws 8 can be connected to a simple robotic arm. During the operation of this robotic arm, it can either push the clamping and straightening claws 8 towards the lifting and cutting mechanism, or it can move the clamping and straightening claws 8 along the length of the kelp, thereby stretching the kelp.

[0047] like Figure 1 , Figure 2 and Figure 4 As shown, the cutting clamping part includes a jaw bracket 10 and clamping jaws 9. The jaw bracket 10 is arranged along the length of the seam. Several clamping jaws 9 are provided on the side of the jaw bracket 10 facing the lifting support mechanism, and the clamping jaws 9 are spaced apart along the length of the jaw bracket 10. All the clamping jaws 9 are located between the clamping and straightening jaws 8 at both ends. The side of the jaw bracket 10 away from the lifting support mechanism is connected to the lead screw motor 12.

[0048] In this embodiment, the output shaft of the lead screw motor 12 is fixedly connected to the push lead screw 11. During the operation of the lead screw motor 12, the push lead screw 11 reciprocates axially. During the reciprocating movement of the push cylinder 11, it drives the clamping jaws 9 fixed on the jaw bracket 10 to move toward or away from the lifting and cutting mechanism.

[0049] The internal structure of the gripper 9 is as follows Figure 5 As shown. The clamping jaw 9 includes a housing 15, clamping arms 14 located on the outside of the housing 15, and a clamping cylinder 18 located inside the housing 15. Two clamping arms 14 are provided on the outside of the housing 15, arranged vertically and symmetrically. Both clamping arms 14 are hinged to the housing 15, and both clamping arms 14 are fixedly connected to the inner clamping arms inside the housing.

[0050] The housing has two inner clamping arms, namely an upper inner clamping arm and a lower inner clamping arm. The upper inner clamping arm is fixedly connected to an upper clamping arm located outside the housing, and the lower inner clamping arm is fixedly connected to a lower clamping arm located outside the housing. The upper and lower inner clamping arms are hinged to the same pivot shaft located inside the housing 15, so the upper and lower inner clamping arms are set at a certain angle.

[0051] The housing 15 is equipped with a clamping cylinder 18. The telescopic rod of the clamping cylinder 18 is fixedly connected to the column head 16, which is located between the upper inner clamping arm and the lower inner clamping arm. The cross-sectional shape of the column head 16 is trapezoidal, so that the upper surface of the column head 16 fits with the bottom surface of the upper inner clamping arm and the lower surface of the column head 16 fits with the top surface of the lower inner clamping arm.

[0052] Gas is injected into or discharged from the clamping cylinder 18 through the vent 17. When gas is injected into the clamping cylinder 18 through the vent 17, the telescopic rod of the clamping cylinder 18 drives the column head 16 to move towards the clamping arm. The column head 16 pushes the upper inner clamping arm and the lower inner clamping arm that are in contact with it outward. At this time, the upper clamping arm connected to the upper inner clamping arm and the lower clamping arm support connected to the lower inner clamping arm are also in an open state, and the clamping jaws are in an open state.

[0053] Conversely, when the gas is discharged from the clamping cylinder 18, the telescopic rod of the clamping device 18 drives the column head 16 to move towards the clamping arm. At this time, the upper clamping inner wall and the lower clamping inner wall close inward. The upper clamping arm connected to the upper inner clamping arm and the lower clamping arm support connected to the lower inner clamping arm also gradually close until they are completely fitted. When the upper clamping arm and the lower clamping arm are completely fitted, the kelp can be clamped.

[0054] The internal structure of the clamping and straightening jaws is exactly the same as that of the clamping jaws, so it will not be described again.

[0055] like Figure 1 and Figure 2 As shown, the material collection mechanism is located below the cutting clamping part. The material collection mechanism includes several recycling hoppers 13, which are spaced apart along the length of the gripper bracket 10 and fixed to the frame. In this embodiment, three recycling hoppers 13 are provided. Through these three recycling hoppers, the graded recycling of the kelp head, kelp middle, and kelp tail is basically achieved. During the recycling process, the complete recycling of each part of the kelp is achieved, and no waste of kelp is caused during the recycling process.

[0056] In this application, the number of recycling hoppers 13 is not limited to the three in this embodiment; a greater number of recycling hoppers can be set according to more stringent grading standards. Furthermore, the position of the recycling hoppers 13 on the frame is adjustable. In this case, the recycling hoppers 13 are fixedly connected to the frame by bolts. Multiple bolt holes are provided on the frame, and the position of the recycling hoppers can be changed by altering the position of the bolt holes on the frame when connected to them.

[0057] like Figures 1 to 3 As shown, the lifting and cutting mechanism includes a cylinder 1, a blade holder 2, and several disc blades 5 mounted on the blade holder 2. The cylinder body of the cylinder 1 is fixed to the frame, and the cylinder extension rod 2 is fixedly connected to the blade shaft holder 3 above it. A blade shaft 4 is located at the top of the blade shaft holder 3, and one end of the blade shaft 4 is connected to the output shaft of the blade shaft motor 6. Several disc blades 3 are spaced apart along the axial direction of the blade shaft 4. During operation, the blade shaft motor 6 drives the blade shaft 4 to rotate, thereby driving the disc blades 3 fixed on the blade shaft to rotate. During this process, the cylinder 1 moves the rotating disc blades 3 towards the straightened kelp 7. When the disc blades 3 contact the kelp 7, segmented cutting of the kelp is achieved.

[0058] In this application, in order to achieve the clamping of the cut kelp, the clamping claw 9 is set between two adjacent disc cutters 3. After the disc cutter 3 cuts the kelp 7, the segmented kelp can be clamped by the clamping claw between the two disc cutters.

[0059] In addition, since the kelp varies in length during actual work, the lengths of the cutter shaft 4 and the cutter shaft holder 3 are usually set to be longer to ensure that longer kelp can be cut.

[0060] The working principle of the device is as follows. First, the kelp is transported to the designated position by the conveying device. The clamping and straightening jaws 8 at both ends move from the initial position to the predetermined working position. During the movement to the predetermined working position, the clamping and straightening jaws 8 open under the drive of the internal clamping cylinder. After reaching the predetermined working position, the clamping motor drives the clamping and straightening jaws 8 to close and clamp the kelp.

[0061] During the process of clamping kelp, the kelp can be straightened by manual adjustment; during the process of manually straightening the kelp, the position of the seabed can also be adjusted to facilitate the graded cutting of the seabed.

[0062] Alternatively, a simple robotic arm can be used to move the gripping claws on both sides to clamp the kelp. At the same time, the robotic arm can also be used to move the gripping claws on both sides to adjust the position of the kelp, preparing it in advance for subsequent seabed grading, cutting, and recycling.

[0063] The lead screw motor 12 provides power to drive the lead screw 11, which in turn pushes the gripper bracket 10 to move from the initial working position to the predetermined working position. During the movement of the gripper bracket 10 and the gripper 9, the gripper 9 opens under the drive of the internal motor as it moves towards the predetermined working position. Upon reaching the predetermined working position, the gripper 9 closes and clamps under the drive of the internal clamping cylinder. At this point, the straightened kelp is clamped by the straightening gripper 8.

[0064] Cylinder 1 provides power to drive cylinder extension rod 2, which extends and pushes the cutter shaft holder 3, which is fixedly connected to it, to move to a predetermined working position. At the same time, the cutter shaft motor 6 on the cutter shaft holder 3 is activated, which drives the cutter shaft 4 and the disc cutter fixed on the cutter shaft 4 to rotate.

[0065] After reaching the designated position, driven by cylinder 1, the disc cutter 5 continues to move upward, and the disc cutter 5 comes into contact with the kelp 7. The high-speed rotating disc cutter 5 cuts the kelp 7 into segments.

[0066] After cutting, cylinder 1 provides power to retract cylinder extension rod 2, which in turn drives the disc cutter 5 back to its initial position. Simultaneously, lead screw motor 12 drives the gripper bracket 10 back to its initial position via lead screw 11. At this time, the gripping jaws 9 fixed on the gripper bracket 10 move to their initial positions, and the gripping straightening jaws 8 on both sides return to their initial positions synchronously with the gripping jaws 9. The gripping straightening jaws 8 and gripping jaws 9 then clamp the cut kelp back to their initial positions.

[0067] Multiple recycling hoppers 13 are located below the initial position. Both the clamping and straightening jaws 8 and the clamping jaws 9 are open. The cut kelp is then placed into the recycling hoppers 13, completing the kelp clamping, cutting, and collection process. During the cutting process, kelp of different thicknesses is cut and collected into different recycling hoppers, achieving the grading, cutting, and separate collection of different parts of the kelp. After the operation is completed, the process is repeated once the next piece of kelp reaches the designated working position.
