[0020] Example 1

[0021] like Figures 1-9 As shown, the feeding mechanism for the kelp knotting machine includes a feeding module 4, which includes an active friction wheel 401, a driven friction wheel 402, and a kelp conveying plate 403. The active friction wheel 401 and the driven friction wheel 402 are arranged side by side below the friction wheel mounting plate 503, with a gap between them to accommodate kelp strips. The friction force of the active friction wheel 401 and the driven friction wheel 402 is used to convey the kelp, applying pressure to the kelp from both sides. This solves the problem of kelp slippage affecting feeding in existing equipment, ensuring that the kelp is fed in place without manual assistance, thus improving knotting efficiency and success rate. The inner ring of the active friction wheel 401 is fixedly connected to the friction wheel one-way shaft module 404 via a coupling. The friction wheel one-way shaft module 404 is equipped with a one-way locking structure, allowing only unidirectional rotation of the active friction wheel. The friction wheel one-way shaft module 404 is connected to the drive mechanism 6, and its bottom end is rotatably connected to the motor mounting plate 504 via a flange bearing. The top end of the friction wheel one-way shaft module 404 is rotatably connected to the friction wheel mounting plate 503 via a flange bearing, and a rotary encoder 405 is mounted on the top end. The number of rotations of the active friction wheel is controlled by setting the rotary encoder to control the output length of the kelp strips. The inner ring of the driven friction wheel 402 is fixedly connected to the friction wheel fixed short shaft 406. The top end of the friction wheel fixed short shaft 406 is rotatably connected to the friction wheel mounting plate 503 via a flange bearing, and its lower end passes through the kelp. The kelp conveyor plate 403 has a feed inlet 4031 located at the head end below the active friction wheel 401 and the driven friction wheel 402 and extending to the left. Circular holes 4032 are provided on the kelp conveyor plate 403 corresponding to the active and driven friction wheels 401 and 402 to prevent interference with their rotation. Support plates 4033 are provided on both sides of the kelp conveyor plate 403 and are fixedly connected to the friction wheel mounting plate 503 to ensure the structural stability of the kelp conveyor plate 403. The end of the kelp conveyor plate 403 extends towards the auxiliary knotting module 2 and has a discharge port 4034. A kelp cutting mechanism 407 is installed at the discharge port 4034 to cut the kelp into 15-18cm straight strips, which facilitates rapid clamping movement of the auxiliary knotting mechanism and improves knotting efficiency.

[0022] The driving mechanism 6 comprises a stepping motor 601, a driving gear 602 and a driven gear 603. The stepping motor 601 is installed below a motor fixing plate 604. The output shaft of the stepping motor 601 is connected with the driving gear 602 after penetrating through the motor fixing plate 604 to drive the rotation of the driving gear 602. The driven gear 603 is installed on one side of the driving gear 602 and is engaged with the driving gear 602. The inner ring of the driven gear 803 is fixedly connected with the friction wheel one-way shaft module 404. When the driven gear 803 rotates, the driving friction wheel 401 is synchronously rotated by the friction wheel one-way shaft module 404 (except when the stepping motor reverses). The stepping motor 601 is used as the power source. The rotation of the stepping motor 601 drives the driving gear 602 to synchronously rotate the driven gear 603. The synchronous transmission of the driving gear 602 and the driven gear 603 provides power for the feeding module 4 and the pneumatic clamping jaw module 3, which not only ensures the consistency of the action and improves the efficiency, but also enhances the connection compactness between the components and improves the portability of the device.

One end of the pneumatic clamping jaw module 3 is installed on the support 5 at the left end of the main body bottom plate 1, and the other end extends to the pneumatic clamping jaw module 2 and is used for clamping the two ends of the annular kelp strip and moving to make the end of the kelp strip pass through the middle of the annular kelp strip to be wound and knotted. The feeding module 4 is installed above the pneumatic clamping jaw module 3 and is used for conveying the kelp strip from the left end of the main body bottom plate 1 to the right end opposite to the auxiliary knotting module 2, so as to facilitate the auxiliary knotting module 2 to clamp the two ends of the kelp strip.

[0024] The auxiliary knotting module 2, the pneumatic clamping jaw module 3 and the main body frame of the kelp knotting machine are integrated. The auxiliary knotting module 2 forms a crossed annular shape of the kelp strip. Then the two ends of the annular kelp strip are clamped by the pneumatic clamping jaw module 3 and moved to make the end of the kelp strip pass through the middle of the annular kelp strip to be wound and knotted. The modules are cooperated to realize efficient knotting and solve the problems of large size, complex knotting action and low success rate of the kelp knotting device in the prior art.

The second auxiliary vertical plate 202 is provided with an arc-shaped second gap 2021 at the upper part. The second gap 2021 is provided with a second guide rail 2022. The second guide rail 2022 is slidingly connected with a second slider 2023 matched with the second guide rail 2022. The second slider 2023 is fixedly installed with the second clamping mechanism 204. The second clamping mechanism 204 is connected with a second driver. The second driver drives the second clamping mechanism 204 to slide along the second guide rail 2022. The bottom of the second slider 2023 is provided with a T-shaped groove matched with the arc-shaped T-shaped sliding part of the second guide rail 2022, so as to limit the sliding of the second slider 2023 along the second guide rail 2022 and avoid slipping.

When the first clamping mechanism 203 is located at the top left end of the first guide rail 2012 and the second clamping mechanism 204 is located at the lower left end of the second guide rail 2022, the openings of the first clamping mechanism 203 and the second clamping mechanism 204 are opposite to the discharge port of the feeding module 4, so as to achieve the purpose of accurately clamping the head end and the tail end of the kelp strip by the first clamping mechanism 203 and the second clamping mechanism 204, respectively. After moving, the kelp strip is driven to form a ring shape with the two ends crossed. The auxiliary knotting mechanism moves along the first guide rail and the second guide rail through the first clamping mechanism and the second clamping mechanism, so as to realize the stable clamping of the kelp and the fast looping by moving up and down. The kelp ring has a controlled space and the positions of the two ends of the kelp strip are staggered, which is beneficial to the clamping and knotting of the subsequent pneumatic clamping jaw module 3 and improves the knotting success rate and knotting efficiency.

The middle part of the first driving rope 2054 is fixedly connected with the first driving wheel 2051. The two ends of the first driving rope 2051 are respectively wound around the first head orientation wheel 2052 and the first tail orientation wheel 2053 and are then connected with the two sides of the first clamping mechanism 203. The first head orientation wheel 2052 and the first tail orientation wheel 2053 are both provided with grooves for accommodating the first driving rope 2054, so as to prevent the first driving rope 2054 from slipping off. The first driving motor 2055 is rotationally driven to rotate the first driving wheel 2051, so that the first driving rope 2054 on the two sides is retracted or elongated, thereby driving the first clamping mechanism 203 to move upward or downward along the first guide rail 2012. The second driver is the same as the first driver in structure and is installed on the second auxiliary vertical plate 202.Further, the first clamping mechanism 203 comprises a first fixed auxiliary clamping plate 2031, a first movable auxiliary clamping plate 2032 and a first electromagnet 2033. The first fixed auxiliary clamping plate 2031 comprises a first fixed auxiliary clamping plate bottom plate 20311 and first fixed auxiliary clamping plate long side plates 20312 and first fixed auxiliary clamping plate short side plates 20313 vertically arranged upwards at both ends of the first fixed auxiliary clamping plate bottom plate 20311. The first fixed auxiliary clamping plate bottom plate 20311 is fixedly installed on the top end surface of the first sliding block 2013. The first fixed auxiliary clamping plate short side plates 20313 are located outside the first auxiliary vertical plate 201 and a strip-shaped gap 20314 is formed in the lower part of the first fixed auxiliary clamping plate short side plates 20313. The strip-shaped gap 20314 is in a U shape and penetrates through one end of the first fixed auxiliary clamping plate short side plates 20313. The first movable auxiliary clamping plate 2032 comprises a first movable auxiliary clamping plate bottom plate 20321. The first movable auxiliary clamping plate bottom plate 20321 penetrates through the first fixed auxiliary clamping plate short side plates 20313 through the strip-shaped gap 20314 and is provided with a first movable auxiliary clamping plate long side plate 20322 upwards at the inner end and a first movable auxiliary clamping plate short side plate 20323 downwards at the outer end. An opening is formed between the first movable auxiliary clamping plate long side plate 20322 and the first fixed auxiliary clamping plate long side plate 20312 for clamping the kelp strips.

A first left tension spring 2036 and a first right tension spring 2037 are respectively sleeved on the first clamping plate left mounting shaft 2034 and the first clamping plate right mounting shaft 2035. The two ends of the first left tension spring 2036 and the first right tension spring 2037 are fixedly connected with the first fixed auxiliary clamping plate short side plates 20313 and the first movable auxiliary clamping plate long side plate 20322, respectively. The first electromagnet 2033 is fixedly installed outside the first sliding block 2013 and is connected with the first movable auxiliary clamping plate short side plate 20323 through magnetic attraction. The first electromagnet 2033 attracts the first movable auxiliary clamping plate short side plate 20323 when powered on, so that the first movable auxiliary clamping plate long side plate 20322 moves inward and closes the first fixed auxiliary clamping plate long side plate 20312 to clamp the kelp strips. When the first electromagnet 2033 is powered off, the elastic restoring force of the first left tension spring 2036 and the first right tension spring 2037 makes the first movable auxiliary clamping plate short side plate 20323 pop outwards, driving the first movable auxiliary clamping plate long side plate 20322 to move outward and loosen the first fixed auxiliary clamping plate long side plate 20312. The second clamping mechanism 204 has the same structure as the first clamping mechanism 203.

[0027] In order to ensure the directional movement of the first dynamic auxiliary clamping plate long side plate, the first dynamic auxiliary clamping plate long side plate 20322 is provided with a positioning pin 2038 on one side thereof towards the first fixed auxiliary clamping plate long side plate 20312, and the head end of the positioning pin 2038 is a pointed portion, and the first fixed auxiliary clamping plate long side plate 20312 is provided with a positioning hole 20315 corresponding to the positioning pin 2038.

[0028] The clamping mechanism adopts a fixed auxiliary clamping plate and a dynamic auxiliary clamping plate, and is provided with electromagnetic driving and spring tension recovery. The fixed auxiliary clamping plate and the dynamic auxiliary clamping plate have a large flat clamping space, and the clamping success rate of the kelp strips is high, the movement process is stable, and the kelp strips are not easily damaged. The electromagnetic driving is not only simple to control, but also has good self-adaptive ability, can quickly realize the closing of the clamping mechanism, and cooperates with the spring to realize the automatic and rapid recovery of the fixed auxiliary clamping plate and the dynamic auxiliary clamping plate. The clamping mechanism is small and compact in structure as a whole, realizes the process requirement of kelp winding knotting by using rope driving, and the rope driving has good self-adaptive ability as flexible driving, so that the clamping mechanism can freely move on the arc-shaped track, the speed is faster, the movement is more flexible, the kelp coiling action is simpler and more coherent, and the efficiency of kelp knotting is improved.

The angle adjusting block 310 is used to support and stabilize the first linear guide rail 309, so as to ensure the linear movement of the first rack 306 along the first linear guide rail 309.

[0030] The structure of the second pneumatic clamping jaw 302 is the same as that of the first pneumatic clamping jaw 301, and the second connecting mechanism is connected with the driving mechanism in the same way as the first connecting mechanism. The driving mechanism drives the first rack and the second rack to move left or right, thereby driving the first pneumatic clamping jaw and the second pneumatic clamping jaw to move left or right. When the first pneumatic clamping jaw 301 and the second pneumatic clamping jaw 302 move right to the position, the clamping ends of the first pneumatic clamping jaw 301 and the second pneumatic clamping jaw 302 are in a crossed state, and the first pneumatic clamping jaw 301 is located above the second pneumatic clamping jaw 302. The clamping end of the first pneumatic clamping jaw 301 is opposite to the second clamping mechanism 204, and the clamping end of the second pneumatic clamping jaw 302 is opposite to the first clamping mechanism 203.

The driving mechanism 6 of the feeding module 4 and the pneumatic clamping jaw module 3 is integrated, and is installed on the motor fixing plate 504 and the friction wheel mounting plate 503 of the support 5. This not only saves energy, but also improves the continuity of the action, reduces the equipment arrangement, and improves the compactness of the equipment structure.

[0033] In order to adapt to production demand, improve the clamping accuracy of the pneumatic gripper module 2 on the kelp strip, the motor fixing plate 504 is provided with a first angle adjusting groove 5041 and a second angle adjusting groove on the outside of the driving gear and the driven gear, the first angle adjusting block 309 is embedded into the motor fixing plate through the first angle adjusting groove 5041 and is fixed by bolts, and the second angle adjusting block is embedded into the motor fixing plate through the second angle adjusting groove and is fixed by bolts.

[0034] Working process: the step motor 601 is rotated forward, the kelp strip is put into the gap between the driving friction wheel 401 and the driven friction wheel 402, the kelp strip is moved to the right along the kelp conveying plate 403 by the thrust of the driving friction wheel 401 and the driven friction wheel 402, and is pushed to the second fixed auxiliary clamping plate and the second movable auxiliary clamping plate of the second clamping mechanism 204 until the end of the kelp strip falls therebetween, at this time, the kelp strip has moved a set distance set by the rotary encoder 405, the end of the kelp strip is located between the first fixed auxiliary clamping plate 2031 and the first movable auxiliary clamping plate 2032, and the kelp cutting mechanism 407 at the end of the kelp conveying plate 203 cuts the kelp strip; when the step motor 601 is reversed, the driving friction wheel 401 does not rotate due to the use of the one-way shaft module 404 of the friction wheel, and the step motor 601 starts feeding when rotated forward.
