Description
Technical Field
[0001] The utility model belongs to the technical field of Gracilaria lemaneiformis planting and processing, and particularly relates to a fixed-length cutting device for the longline culture of algae plants. Background Technique
[0002] In China, a large number of algae are cultured by the longline culture method, and Gracilaria lemaneiformis is one of them. Gracilaria lemaneiformis is the main Gracilaria seaweed cultivated on a large scale in China. It is native to the Shandong Peninsula. Due to its relatively good quality of agar produced, it is an irreplaceable important raw material for agar production. As a thickener, forming agent, stabilizer, etc., agar is widely used in food and chemical industries such as dairy products, jelly, cold drinks, and bacterial culture media. And with the further development of its functions, the demand for Gracilaria lemaneiformis raw materials is constantly expanding. In addition, Gracilaria lemaneiformis is also one of the main baits for abalones. In recent years, due to the improvement of people's living standards and the booming development of the abalone industry, the market gap of Gracilaria lemaneiformis has been further exacerbated.
[0003] Longline culture refers to a culture method that uses ropes and floating objects as culture tools, fixes the ropes at the bottom of the sea, and sets appropriate intervals between the ropes for hanging or supporting the cultured objects. Artificial large-scale cultivation of Gracilaria lemaneiformis adopts vegetative propagation. Multistrand nylon ropes or polyethylene ropes are used to clamp Gracilaria lemaneiformis seedlings in their gaps. After clamping the seedlings, the ropes need to be cut into the required lengths, and the rope lengths are determined according to the width of the floating stems, the culture environment, and other factors. The cutting of the ropes is generally carried out by workers using sharp cutting tools, that is, the traditional manual cutting method. In the process of cutting, it is difficult to maintain the stability and uniform force of the cutting tools. The lengths of the cut ropes cannot be guaranteed to be accurate and the edges may not be neat enough. The efficiency is low, the labor cost is high, it is difficult to meet the needs of large-scale longline culture, and there is a certain safety risk that the cutting tools may accidentally injure oneself or others.

The transmission mechanism is arranged along the length direction of the frame, and one end of the transmission mechanism close to the rope releasing mechanism is the feeding end, and the end far from the rope releasing mechanism is the discharging end;
[0007] A plurality of rope clamping mechanisms are provided and evenly distributed at intervals on the transmission mechanism. The rope clamping mechanism is provided with opening and closing finger grippers. The finger grippers clamp the rope released by the rope releasing mechanism at the feeding end, and drive the rope to move along with the transmission mechanism towards the discharging end to tighten the rope. The hot melt cutter is arranged above the transmission mechanism and moves up and down to cut the rope.
[0008] Furthermore, the transmission mechanism is an annular transmission belt or a transmission chain mechanism. When the rope clamping mechanism moves to the feeding end, its finger grippers close to clamp the rope; when the rope clamping mechanism moves to the discharging end, its finger grippers open to release the rope, and the cut rope falls from the discharging end and is collected.
[0009] Furthermore, a track plate is provided on the frame. The track plate is arranged along the length direction of the frame, and a track with variable tracks at both ends is provided on the track plate; the rope clamping mechanism includes a clamping seat, finger grippers, a push rod, a spring, and rollers. The clamping seat is fixed on the transmission mechanism. Two finger grippers are provided and are both rotatably arranged on the clamping seat. A spring is connected between the two finger grippers; the push rod is arranged up and down on the clamping seat and is located between the two finger grippers. The top of the push rod abuts and cooperates with the two finger grippers respectively. The bottom of the push rod is provided with rollers, and the rollers are in rolling cooperation in the track and move up and down according to the variable track of the track, so that the push rod moves up and down relative to the clamping seat to push the two finger grippers to rotate and open and close.
[0010] Furthermore, the track is arranged on the front side of the track plate along the length direction of the frame. The track is an annular track with rounded corners at both ends, including a first track and a second track that are parallel up and down, and a rounded corner track located between the first track and the second track. The radius of the rounded corner track gradually increases from top to bottom to form a cam track, and the rounded corner radii at both ends of the transmission mechanism remain unchanged; when the rollers move from the first track down to the second track, they move up relative to the clamping seat at the same time, so that the push rod pushes the two finger grippers to open.
[0011] Furthermore, the top of the push rod is provided with a top pushing part, the side surface of the top pushing part is an arc surface, and a top pushing screw is provided in the middle of the finger gripper, and the top pushing screw abuts against the side surface of the top pushing part.
[0012] Furthermore, the transmission mechanism is a transmission chain mechanism, including a chain and a driving sprocket and a driven sprocket that mesh with the chain. The driving sprocket and the driven sprocket are arranged on the front sides at both ends of the track plate. The chain is arranged parallel to the track plate before and after. The clamping seat is fixed on the rear side of the chain. A plurality of conveying plates are also provided on the rear side of the chain. The plurality of conveying plates are evenly distributed at intervals along the length direction of the chain.

An optoelectronic sensor is also arranged on the frame. The optoelectronic sensor is located on the right side of the hot melt cutter and is electrically connected to the electric push rod. When the rope clamping mechanism moves to trigger the optoelectronic sensor, the electric push rod extends to push the hot melt cutter to cut the rope.
[0015] Furthermore, the optoelectronic sensor includes a transmitter and a receiver. The transmitter and the receiver are respectively arranged on the front and back sides of the transmission mechanism. When the rope clamping mechanism moves between the transmitter and the receiver to block the receiver from receiving the signal, the electric push rod is triggered to extend downward.
[0016] Furthermore, the rope releasing mechanism is a rope rolling drum. The rolled and twisted rope is wound on the rope rolling drum. The position between the rope rolling drum and the frame is the seedling clamping station. The rope rolling drum rolls to release the rope, and workers clamp the Gracilaria lemaneiformis seedlings into the rope at the seedling clamping station.
[0017] After adopting the above scheme, the beneficial effects of the utility model are as follows:

The rope releasing mechanism is arranged on one side of the frame to release the rolled and twisted rope. The rope clamping mechanism can clamp the released rope at the feeding end and drive the rope to move, thereby tightening the rope. Since the rope released by the rope releasing mechanism is already rolled and twisted, workers can clamp the Gracilaria lemaneiformis seedlings into the rope between the rope releasing mechanism and the frame. Then, the rope with the clamped Gracilaria lemaneiformis seedlings will be driven by the rope clamping mechanism to move towards the discharging end. When the rope clamping mechanism moves to a suitable position, the hot melt cutter can cut the rope, thereby completing the fixed-length segmentation operation of longline aquaculture.
[0019] The utility model completes the fixed-length segmentation operation of longline aquaculture with mechanical equipment throughout the process. The length of the segmented ropes can be guaranteed to be consistent and accurate. Moreover, when using the hot melt cutter to cut the rope, there will be no problem that the cut edge of the rope is not neat enough. When cutting the rope, the cut section of the rope can be melted and welded, and the clamped Gracilaria lemaneiformis seedlings will not become loose. The work is stable, reliable, and efficient, reducing the use of manpower and saving labor costs. Brief Description of the Drawings

[0032] The following describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.
[0033] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.
[0034] As shown Figure in the figure, the utility model provides a fixed-length splitting device for longline cultivation of algae plants, which includes a rope releasing mechanism 1, a frame 2, and a transmission mechanism 3, a rope clamping mechanism 4, and a thermal rope fusing mechanism 5 arranged on the frame 2. The rope releasing mechanism 1 is arranged on one side of the frame 2 to release the twisted rope 6. The transmission mechanism 3 is arranged along the length direction of the frame 2, and one end of the transmission mechanism 3 close to the rope releasing mechanism 1 is the feeding end 31, and the end far from the rope releasing mechanism 1 is the discharging end 32. A plurality of the rope clamping mechanisms 4 are provided and evenly distributed at intervals on the transmission mechanism 3. The rope clamping mechanism 4 is driven by the transmission mechanism 3. The rope clamping mechanism 4 is provided with open and closed clamping fingers 42. When the clamping fingers 42 are at the feeding end 31, they can clamp the rope 6 released by the rope releasing mechanism 1, and can drive the rope 6 to move along with the transmission mechanism 3 towards the discharging end 32 to tighten the rope 6.
[0035] Specifically, the rope releasing mechanism 1 can be a rope rolling drum. The rope 6 for seedling clamping is wound on the rope rolling drum. The rope 6 is twisted by several thin ropes. While the clamping fingers 42 of the rope clamping mechanism 4 clamp one end of the rope 6 and move it towards the discharging end 32, the rope rolling drum rotates to release the rope 6. Between the rope rolling drum and the frame 2 is a seedling clamping station 7, where workers can clamp Gracilaria lemaneiformis seedlings into the already twisted several ropes 6 released by the rope rolling drum.
[0036] The thermal rope fusing mechanism 5 includes a frame 51 and a hot melting cutter 52. The hot melting cutter 52 is arranged above the transmission mechanism 3 to move up and down. When the clamping fingers 42 move one end of the rope 6 to a suitable position, the hot melting cutter 52 moves down to cut the rope 6, and at the same time of cutting the rope 6, it can also weld the cut section of the rope 6.
[0037] Furthermore, the transmission mechanism 3 is an annular transmission belt or a transmission chain mechanism. When the rope clamping mechanism 4 moves to the feeding end 31, its clamping fingers 42 close to clamp the rope 6, and then drive the rope 6 to move towards the discharging end 32. After the rope 6 is cut, the rope clamping mechanism 4 moves to the discharging end 32, and its clamping fingers 42 open to release the rope 6. The cut rope 6 will fall from the discharging end 32 and be collected. At the same time, the next rope clamping mechanism 3 can move to the feeding end 31 to continue clamping the rope 6 and repeat the steps of the previous rope clamping mechanism 3, so as to realize the continuous operation of fixed-length rope cutting in a cycle.
[0038] Focus on referring to 9, a track plate 8 is provided on the frame 2. The track plate 8 is arranged along the length direction of the frame 2, and a track with variable tracks at both ends is provided on the track plate 8. The rope clamping mechanism 4 includes a clamping seat 41, clamping fingers 42, a push wheel rod 43, a spring 44, and a roller 45. The clamping seat 41 is fixed on the transmission mechanism 3. There are two clamping fingers 42, and both are rotatably arranged on the clamping seat 41. Specifically, they can be rotatably connected to the clamping seat 41 through a rotating shaft. A spring 44 is connected between the two clamping fingers 42; the push wheel rod 43 is movably arranged up and down on the clamping seat 41 and is located between the two clamping fingers 42. The top of the push wheel rod 43 is in abutting cooperation with the two clamping fingers 42. A roller 45 is arranged at the bottom of the push wheel rod 43, and the roller 45 is in rolling cooperation in the track. Since the clamping seat 41 is fixed to the transmission mechanism 3, the entire rope clamping mechanism 4 will be driven by the transmission mechanism 3, and the roller 45 will move in the track. If the track changes, the roller 45 will move up and down. As a result, the push wheel rod 43 will move up and down relative to the clamping seat 41. When the push wheel rod 43 moves upward relative to the clamping seat 41, it will push the two clamping fingers 42 to rotate and open to release the rope 6. At the same time, the spring 44 is stretched; on the contrary, when the push wheel rod 43 moves downward relative to the clamping seat 41, the spring 44 resets to drive the two clamping fingers 42 to clamp the rope 6. Through this principle, the track can be changed at the feeding end 31 and the discharging end 32, so that the rope clamping mechanism 4 clamps the rope 6 at the feeding end 31 and releases the rope 6 at the discharging end 32.
[0039] For key reference Figure 10 , specifically, the track is arranged on the front side surface of the track plate 8 along the length direction of the frame 2. The track is an annular track with rounded corners at both ends, specifically including a first track 81 and a second track 82 that are parallel up and down, and a rounded corner track 83 located between the first track 81 and the second track 82. The radius of the rounded corner track 83 gradually increases from top to bottom to form a cam track; the transmission mechanism 3 is arranged parallel to the track plate 8 front and back. The rounded corner radii at both ends (feeding end 31 and discharging end 32) of the transmission mechanism 3 are constant; when the roller 45 moves from the first track 81 downward to the second track 82, since the clamping seat 41 is driven by the transmission mechanism 3, the radius of the circular motion of the clamping seat 41 at the discharging end 32 is constant. When the roller 45 moves in the rounded corner track 83, as the radius of the rounded corner track 83 increases, the roller 45 will move upward relative to the clamping seat 41, causing the push wheel rod 43 to move upward to push the two clamping fingers 42 to open, that is, the rope clamping mechanism 4 releases the rope 6 at the discharging end 32. On the contrary, the rope clamping mechanism 4 can clamp the rope 6 at the feeding end 31.
[0040] Further, a pushing portion 46 is provided at the top of the pushing wheel rod 43, and the side surface of the pushing portion 46 is an arc surface. A pushing screw 47 is provided in the middle of the clamping finger 42. When the roller 45 rolls in the first track 81, the top side surface of the pushing portion 46 abuts against the bottom side surface of the pushing screw 47, and the two clamping jaws are combined to clamp the rope 6. When the roller 45 is in the rounded corner track 83 and the second track 82, the pushing wheel rod 43 moves upward relative to the clamping seat 41, and the pushing portion 46 pushes the two pushing screws 47 upward until the middle side surface of the pushing portion 46 abuts against the middle side surface of the pushing screw 47, so that the two clamping fingers 42 are opened to release the rope 6. The cooperation of the pushing portion 46 and the pushing screw 47 is provided, which easily realizes the opening and closing of the pushing wheel rod 43 to push the clamping fingers 42. Moreover, the side surfaces of the pushing portion 46 and the pushing screw 47 are both arc surfaces, with small friction and easy to push.
[0041] Preferably, three clamping rope mechanisms 4 are provided, and the distances between the three clamping rope mechanisms 4 are the same. The first clamping rope mechanism 4 first clamps one end of the rope 6 and moves it towards the discharging end 32. After the second clamping rope mechanism 4 moves to the feeding end 31 and clamps the rope 6, the hot melt cutter 52 cuts the rope 6 on one side of the clamping rope mechanism 4 close to the discharging end 32. After the first clamping rope mechanism 4 moves to the position of the rounded corner track 83 at the discharging end 32, it releases the rope 6, and a cut section of the rope 6 falls from the discharging end 32. The second clamping rope mechanism 4 clamps one end of the rope 6 and continues to move towards the discharging end 32. The third clamping rope mechanism 4 moves to the feeding end 31 and clamps the rope 6, and the hot melt cutter 52 cuts the rope 6 downward again to complete the cutting of a new section of the rope 6. Then the third clamping rope mechanism 4 clamps one end of the rope 6 and moves towards the discharging end 32 to put down the rope 6. Then the first clamping rope mechanism 4 moves to the feeding end 31 to clamp the rope 6, and the hot melt cutter 52 continues the cutting action to cut a new section of the rope 6 again. In this way, the three clamping rope mechanisms 4 continuously perform operations of clamping the rope, driving the rope to move, and releasing the rope, and the length between the two clamping rope mechanisms 4 is the length of the cut rope 6, realizing the fixed-length cutting of the rope 6. The length of the rope 6 can be determined by the distance between the two clamping rope mechanisms 4. Therefore, the clamping rope mechanisms 4 are not limited to three and can be adjusted according to actual situations.
[0042] Focus on referring to Figure 1-10, the transmission mechanism 3 is preferably a transmission chain mechanism. It is easier to install the rope clamping mechanism 4 using a transmission chain mechanism. The transmission chain mechanism includes a chain 33, a driving sprocket 34 meshing with the chain 33, and a driven sprocket 35. The driving sprocket 34 and the driven sprocket 35 are arranged on the front side at both ends of the track plate 8. The chain 33 is arranged parallel to the track plate 8 in the front and back directions. The clamping seat 41 is fixed to the rear side of the chain 33 and thus located between the chain 33 and the track plate 8. The roller 45 can roll in the track. A plurality of conveying plates 9 are further provided on the chain 33. The plurality of conveying plates 9 are evenly distributed at intervals along the length direction of the chain 33 and are parallel to the clamping seat 41. The conveying plates 9 are also fixed to the rear side of the chain 33. A motor is provided on the frame 2 at the position of the driving sprocket 34. The motor drives the driving sprocket 34 to rotate, so that the chain 33 drives the clamping seat 41 and the conveying plates 9 to move. When the rope clamping mechanism 4 clamps the rope 6 and drives the rope 6 to move, the rope 6 is located on the conveying plate 9. After the rope clamping mechanism 4 releases the rope 6 at the discharge end 32, the cut rope 6 moves with the conveying plate 9 and falls from the discharge end 32. Since the rope clamping mechanism 4 and the conveying plates 9 are fixed to the rear side of the chain 33, to maintain the front and back balance of the chain 33, a guide rail 23 is provided on the front side of the chain 33 on the frame 2 to limit the front side of the chain 33. The guide rail 23 can also prevent the rope 6 from separating from the conveying plate 9 at the front side. And hooks 91 are provided on the conveying plates 9. The hooks 91 can prevent the rope 6 from separating from the conveying plate 9 at the rear side.
[0043] With key reference to Figure 3-7 、 Figure 6-8 and Figure 3 Figure 2 Figure 9 Figure 10 , a frame 51 is provided above the feeding end 31 of the frame 2. An electric push rod 53 is provided on the frame 51. The hot melt cutter 52 is arranged on the electric push rod 53 and moves up and down driven by the electric push rod 53. Specifically, taking the rope releasing mechanism 1 arranged on the right side of the frame 2 as an example, the right end of the transmission mechanism 3 is the feeding end 31, and the left end is the discharge end 32. An optical sensor is also provided on the frame 2. The optical sensor is located on the right side of the hot melt cutter 52 and is electrically connected to the electric push rod 53. Specifically, both the optical sensor and the electric push rod 53 are electrically connected to a control module (not shown in the figure). When the rope clamping mechanism 4 moves to the position of the optical sensor, the optical sensor is triggered. The optical sensor transmits information to the control module, and the control module controls the electric push rod 53 to extend to push the hot melt cutter 52 to cut the rope 6, completing the cutting of the rope 6. After cutting, the previous rope clamping mechanism 4 can drive the cut rope 6 to move towards the discharge end 32, and the next rope clamping mechanism 4 located at the feeding end 31 continues to drive the rope 6 to move to complete the cutting of the next section of the rope 6.
[0044] Further, the photoelectric sensor includes a transmitter 21 and a receiver 22. The transmitter 21 and the receiver 22 are respectively arranged on the front and rear sides of the transmission mechanism 3. The transmitter 21 can emit a photoelectric signal to the receiver 22. When the rope clamping mechanism 4 moves between the transmitter 21 and the receiver 22, the rope clamping mechanism 4 will block the receiver 22 from receiving the photoelectric signal, thereby sending information to the control module, and the control module will control the electric push rod 53 to extend downward.
[0045] The working process of the present utility model is as follows: First, the first rope clamping mechanism 4 clamps one end of the rope 6 at the feeding end 31 and moves it towards the discharging end 32 (to the left). The rope rolling drum rotates under the pulling force of the rope clamping mechanism 4 to release the twisted rope 6. Workers clamp the asparagus seedlings into the rope 6 at the seedling clamping station 7. Then, the second rope clamping mechanism 4 moves to the feeding end 31, its clamping fingers 42 open to clamp the rope 6, and then this rope clamping mechanism 4 moves between the transmitter 21 and the receiver 22 to trigger the electric push rod 53. The electric push rod 53 extends downward to drive the hot melt cutter 52 to move downward. The hot melt cutter 52 cuts the rope 6 on the left side of the second rope clamping mechanism 4, and melts the cut section of the rope 6 to prevent the clamped asparagus seedlings from loosening; the first rope clamping mechanism 4 then moves to the rounded corner track 83 at the discharging end 32, its clamping fingers 42 open to release the rope 6, and the rope 6 falls from the discharging end 32. Then the first rope clamping mechanism 4 moves to the second track 82. At this time, the second rope clamping mechanism 4 then drives the rope 6 to move towards the discharging end 32. The third rope clamping mechanism 4 moves to the feeding end 31 to clamp the rope 6, and then triggers the photoelectric sensor to cut the rope 6, completing the fixed-length cutting of a new section of the rope 6. Then the first rope clamping mechanism 4 returns from the second track 82 to the first track 81 and clamps the rope 6 to continue to complete the cutting of the next section of the rope 6. In this way, the continuous fixed-length cutting of the rope 6 is realized by cycling.
[0046] The present utility model uses the rope releasing mechanism 1, the rope clamping mechanism 4, and the transmission mechanism 3 to continuously release, tighten, and fix the length of the rope 6, and then continuously divides the rope 6 through the hot melt cutter 52. The length of the divided rope 6 can be guaranteed to be consistent and accurate. Moreover, when using the hot melt cutter 52 to cut the rope 6, there will be no problem that the cut edge of the rope 6 is not neat enough. When cutting the rope 6, the cut section of the rope 6 can be melted, and the clamped asparagus seedlings will not loosen. The work is stable and reliable, with high efficiency, reduces the use of manpower, and saves labor costs.
[0047] The above is only the preferred embodiment of the present utility model, and it does not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
