[0002] Swimming crab, also known as deep-sea swimming crab, three-spot crab, crab or crab, is a common edible crab belonging to the order Decapoda and the family Portunidae. Swimming crabs are mainly distributed in the western Pacific and Indian Oceans, including the coastal areas of China, Japan, South Korea and other places, and are one of the important marine fishery resources. In order to facilitate transportation and ensure the activity of swimming crabs, swimming crabs need to be tied.

[0003] With the development of the aquatic product processing industry, the demand for automated and efficient production has become increasingly urgent. An automatic crab bundling device has appeared on the market. The device can bind the bundling rope to the crab in a cross shape to achieve automatic bundling of the crab.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example:

[0031] like Figures 1 to 9 As shown, a swimming crab tying device comprises a base 1 and a limit box 2, the limit box 2 is fixedly arranged on the base 1, and a tying fixing mechanism 3 is arranged on the base 1 on the left and right sides of the limit box 2, the tying fixing mechanism 3 comprises an opening and closing assembly 31, a back plate 32, a limit slide bar 33, a slide plate 34 and an electric push rod 35, the limit slide bar 33 is fixedly installed thereon by bolts, a slidable slide plate 34 is sleeved on the limit slide bar 33, an electric push rod 35 is arranged on the right side of the slide plate 34, and the output end of the electric push rod 35 is fixedly connected to the slide plate 34, the left side surface of the slide plate 34 is fixedly connected to the back plate 32, and the opening and closing assembly 31 is arranged on the upper side of the left end surface of the back plate 32. This design solves the problem that the existing swimming crab tying process mainly relies on manual operation, and it is necessary to manually shape and fix the swimming crab, and then stretch the rubber band and put it on the two large claws of the swimming crab, which not only has high labor intensity and low efficiency, but also the tying effect is difficult to ensure.

[0032] The opening and closing assembly 31 includes a micro conveyor belt 311, a support plate 312, a wheel disc 314, a baffle 317, a slide groove 318, a positioning hole 319 and a special-shaped groove 3120. Four groups of support plates 312 with arc structures are arranged at equal angles on the left side of the back plate 32. The four groups of support plates 312 are cylindrical structures when closed. Four groups of micro conveyor belts 311 are arranged at equal angles on the left side of the back plate 32. The micro conveyor belts 311 are arranged at intervals on the outside of the support plate 312 and their positions correspond to the support plate 312. Four groups of slide grooves 318 are opened inside the support plate 312. A baffle 317 is fixedly provided at the right end of the support plate 312 and passes through the slide groove 318. A rotatable wheel disc 314 is installed on the right side surface of the back plate 32. Four groups of special-shaped grooves 3120 with arc structures are opened at equal angles inside the wheel disc 314. The baffle 317 is located inside the special-shaped groove 3120 and is in contact with the surface of the wheel disc 314. The opening and closing assembly 31 is provided to facilitate supporting and fixing the rubber band, and can stretch the rubber band, thereby facilitating the rubber band to be put on the claws of the swimming crab, thereby tying the swimming crab.

[0033] A baffle 3121 is provided on the circumferential surface of the wheel disc 314, and the baffle 3121 is located at the edge of the special-shaped groove 3120. The baffle 3121 is used to limit the movement of the baffle rod 317 in the special-shaped groove 3120 to prevent the baffle 3121 from excessively moving in the special-shaped groove 3120. When the wheel disc 314 rotates, the baffle rod 317 moves in the special-shaped groove 3120, and the existence of the baffle 3121 ensures that the baffle rod 317 will not escape from the special-shaped groove 3120, thereby ensuring the stability and reliability of the opening and closing assembly 31. The design of the baffle 3121 also makes operation and control more convenient. When rotating the wheel disc 314, the operator can feel the feedback generated when the baffle rod 317 hits the baffle 3121, thereby more accurately controlling the rotation angle of the wheel disc 314, thereby achieving precise control of the opening and closing assembly 31.

[0034] A detachable locking rod 3122 is provided inside the wheel disc 314, and two groups of positioning holes 319 are provided inside the support plate 312. The angle between the two groups of positioning holes 319 is 70°. The locking rod 3122 passes through the wheel disc 314 and can be inserted into the positioning holes 319. The locking rod 3122 and the positioning holes 319 are provided to conveniently fix the wheel disc 314 to the current position, so as to prevent the support plate 312 from moving during the bundling process and affecting the bundling effect. At the same time, by inserting the locking rod 3122 into different positioning holes 319, the opening and closing degree of the support plate 312 can be adjusted.

[0035] A connecting shaft 315 is arranged between the four groups of micro conveyor belts 311. Two groups of connecting shafts 315 are connected to the shafts on the micro conveyor belts 311 through universal couplings 316, ensuring that each group of conveyor belts can maintain synchronization and coordination during movement. A micro motor 313 is fixedly connected to the shaft of the bottom group of micro conveyor belts 311. The micro motor 313 is a power source and can cooperate with the connecting shaft 315 to drive the four groups of micro conveyor belts 311 to rotate synchronously.

[0036] The upper side of the limit box 2 is equipped with an openable and closable movable cover 21, which can be opened when needed to put the swimming crab into the limit box 2 and conveniently taken out after bundling. At the same time, the movable cover 21 can be tightly fitted on the limit box 2 when closed to ensure that the swimming crab will not escape from the limit box 2 during the bundling process. The limit box 2 has limit slots 25 and 22 on both sides near the front end. The slots are used to limit and fix the crab claws of the swimming crab, so that the crab claws of the swimming crab can be extended from the limit box 2 and exposed, and can limit the movement of the crab claws, which is convenient for bundling. The bottom of the limit box 2 is fixedly connected to the base 1 through multiple groups of fixing columns 23.

[0037] A limiting groove 25 is provided on the base 1 directly below the limiting box 2, and a storage box 24 is placed inside the limiting groove 25. The storage box 24 is mainly used to store auxiliary materials such as rubber bands required in the bundling process, so that operators can easily take and store these materials, thereby improving work efficiency.

[0038] The working principle of the swimming crab tying device is as follows: in actual use, firstly, the adjusting wheel 314 is rotated to make the baffle 317 located at the lowest position inside the special-shaped groove 3120, and at this time, the four groups of support plates 312 are closed and cylindrical. Then, the required bundling materials such as rubber bands are taken out from the storage box 24, and the rubber bands are set one by one on the closed support plate 312. Then, the wheel 314 is rotated clockwise, and the baffle 317 is adjusted to the farthest position through the special-shaped groove 3120 on the wheel 314, and the wheel 314 is locked by the locking rod 3122. At this time, the closed support plate 312 is unfolded and the rubber band is supported. Then, the movable cover plate 21 is opened, and the swimming crab is placed in the limit box 2 to ensure that the crab claws of the swimming crab extend from the limit groove 25, and then the movable cover plate 21 is closed, and the closed fixation of the swimming crab is achieved by the movable cover plate 21 cooperating with the limit box 2 to ensure that the swimming crab will not escape from the limit box 2 during the tying process. Start the electric push rod 35, drive the opened support plate 312 to move toward the limit box 2, and make the support plate 312 sleeved on the crab claws of the swimming crab. Then the micro motor 313 is started, and the four groups of micro conveyor belts 311 are driven to rotate synchronously through the connecting shaft 315 and the universal coupling 316. The micro conveyor belts 311 are in close contact with the rubber bands while rotating. When the micro conveyor belts 311 rotate, the friction force is used to drive the rubber bands to move on the support plate 312. When the rubber bands move to the end of the support plate 312, they fall off the support plate 312 and are tightened and sleeved on the crab claws to complete the bundling of the swimming crabs. Then open the movable cover plate 21, take out the tied swimming crabs from the limit box 2, and put the swimming crabs back in, repeat the above steps, and carry out the bundling of the next swimming crab. The swimming crab bundling device realizes fast, accurate and stable bundling of swimming crabs through ingenious mechanical design and automatic control, which not only greatly reduces labor intensity and improves work efficiency, but also ensures the stability and consistency of the bundling effect.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
