Description

Technical Field

[0001] This invention relates to the field of binding machine technology, specifically a buckle-less binding machine for hairy crabs. Background Technology

[0002] my country produces over 800,000 tons of mitten crabs, approximately 4.8 billion crabs, representing a large-scale industry with a value approaching 100 billion yuan. Tying is an essential step in the sale, transportation, and cooking of mitten crabs. It prevents them from crawling around and fighting, ensuring their strength and freshness. This helps reduce mortality during transportation, consumer selection, and stress during cooking, which can lead to leg loss or incomplete crabs. Currently, the commercial tying of mitten crabs relies heavily on manual labor, which is time-consuming and labor-intensive. The high labor intensity and large concentrated workforce during the peak season have become a bottleneck for the industry's sustainable and high-quality development.

[0003] Currently, the vast majority of crab binding tasks are accomplished using binding machines. In traditional binding machine operation, workers manually hold the crab in position, place it in a holding block, and then manually press down initially to ensure the crab is successfully bound. However, this process presents significant safety hazards. Operators inevitably become fatigued during prolonged work, and their fingers can easily come into contact with the binding rope during continuous pressing, leading to injury. Furthermore, after binding, the crabs must be manually removed from the holding block. Because the holding block is usually designed with grooves, retrieving the crabs is extremely inconvenient. These problems not only affect work efficiency but also increase the burden on operators. Summary of the Invention

[0019] This invention provides a buckle-less crab binding machine. Compared with the prior art, it has the following advantages:

[0020] 1. This invention uses an electric push rod to lower an adjusting plate to an appropriate position. The push rod on the adjusting plate moves synchronously. The push rod cooperates with the arc-shaped toothed plate, and the arc-shaped toothed plate is limited by the arc-shaped slider and the arc-shaped groove, thus moving to both sides on the arc-shaped cover. Then, the arc-shaped toothed plate meshes with the adjusting gear. When the adjusting gear rotates, it drives the driving gear to rotate through the rotating shaft. Through the meshing of the driving gear with the outer arc-shaped toothed plate, the outer arc-shaped toothed plate drives the pressing block to adjust its left and right position through the connecting crossbar. Through the synchronous adjustment of the two pressing blocks, the crab, after being fixed in position, is placed in the holding block. The two pressing blocks ensure the stability of the crab in the holding block, eliminating the need for manual pressing of the crab, avoiding the uncertainty and potential risks brought by manual pressing, and improving the safety of the crab binding process.

[0021] 2. In this invention, when the position of the pressing block needs to be adjusted forward and backward, the electric push rod continuously drives the adjusting plate to descend. When the adjusting plate descends to the appropriate position, the hydraulic cylinder moves from the first sliding surface of the arc-shaped baffle to the second sliding surface. When the hydraulic cylinder contacts the second sliding surface, the hydraulic cylinder rotates inward around the flipping rod by the torque of the torsion spring on the flipping block. At the same time, the hydraulic cylinder drives the pressing block to adjust its position, thereby effectively adjusting the position of the pressing block on the crab and further improving the effect of binding the crab.

[0022] 3. In this invention, an electric push rod drives an adjusting plate to continuously descend. The lifting crossbar on the adjusting plate drives a U-shaped pressure rod through a slot and down to the inside of the arc-shaped cover. The toothed block meshes with the lifting gear, which drives the lifting hook to rotate via the lifting shaft. During the continuous rotation of the lifting hook, it hooks onto the rope tied to the crab. Through the continuous rotation of the lifting hook, the crab in the holding block can be effectively rotated to the entrance of the arc-shaped cover. The lifting hook function makes it convenient for personnel to remove the tied crab from the holding block, effectively improving the use effect of the binding machine.

[0023] 4. In this invention, the lifting cylinder is activated according to the size of the crab. The lifting cylinder drives the feeding tube on the lifting frame plate to adjust its position, ensuring that the binding rope delivered by the feeding tube is appropriately sized for the crab. After the feeding tube is adjusted, the crab is placed in the holding block. The binding motor drives the binding shaft to rotate, and the lower bevel gear on the binding shaft rotates. The lower bevel gear meshes with the upper bevel gear, and the connecting drum on the upper bevel gear drives the worm gear on the connecting vertical rod to rotate through the cooperation of the vertical groove and the vertical block. Through the cooperation of the worm gear and the worm wheel, the worm wheel drives the feeding wheel on the feeding shaft to deliver the binding rope in the feeding tube. The rotation of the feeding tube on the mounting plate and the rotation of the feeding wheel ensure that the binding rope on the crab is at an appropriate tension, thereby avoiding damage caused by excessive tightness or detachment caused by excessive looseness.

An adjusting rod 24 is fixedly installed on the adjusting slide rod 23. An outer arc tooth plate 25 is fixedly installed on the adjusting rod 24. A protective plate 26 is fixedly installed on the outer side of the arc-shaped cover 2. The protective plate 26 is located in front of the driving gear 21. The arc tooth plate 15 meshes with the adjusting gear 20, and the outer arc tooth plate 25 meshes with the driving gear 21. The arc slider 16 is slidably installed with the arc groove 17. The adjusting arc groove 22 is slidably installed with the adjusting slide rod 23. The adjusting rod 24 is located on the outside of the arc-shaped cover 2. The connecting crossbar 6 is fixedly installed on the outer arc tooth plate 25.

At the same time, the protective plate 26 is used to block and ensure that the driving gear 21 will not cause any physical harm to personnel when it rotates.

[0039] In this embodiment, the electric push rod 11 drives the adjusting plate 12 to a suitable position, and the push rod 13 on the adjusting plate 12 moves synchronously. With the cooperation of the push rod 13 and the arc-shaped toothed plate 15, the arc-shaped toothed plate 15 is limited by the arc-shaped slider 16 and the arc-shaped slide groove 17, thereby moving to both sides on the arc-shaped cover 2.

[0040] The flipping assembly includes a flipping groove 27 formed on a U-shaped frame plate 7. A flipping rod 28 is rotatably mounted inside the flipping groove 27. A flipping block 29 is fixedly mounted on the flipping rod 28. A torsion spring 40 is fixedly connected to the side end face of the flipping block 29. Symmetrically arranged arc-shaped baffles 30 are fixedly mounted on the front surface of the arc-shaped cover 2. The front surface of the arc-shaped baffles 30 has a first sliding surface 31 and a second sliding surface 32. The end of the torsion spring 40 away from the flipping block 29 is fixedly connected to the inside of the flipping groove 27. The position of the torsion spring 40 is at the flipping rod 28. On the outside, the hydraulic cylinder 8 is fixedly installed on the flipping block 29.

Through the contact between the hydraulic cylinder 8 and the first sliding surface 31 and the second sliding surface 32, it is convenient for the pressing block 9 to press different positions of the crab. The hydraulic cylinder 8 is tightly attached to the arc-shaped baffle 30 by the torque of the torsion spring 40. When the pressing block 9 is adjusted to the left and right, the hydraulic cylinder 8 slides in contact with the first sliding surface 31 and does not slide onto the second sliding surface 32.

[0041] In this embodiment, when the position of the pressing block 9 needs to be adjusted, the electric push rod 11 continuously drives the adjusting plate 12 to descend. When the adjusting plate 12 descends to the appropriate position, the hydraulic cylinder 8 moves from the first sliding surface 31 of the arc-shaped baffle 30 to the second sliding surface 32. When the hydraulic cylinder 8 contacts the second sliding surface 32, the hydraulic cylinder 8 rotates inward around the flipping rod 28 by the torque of the torsion spring 40 on the flipping block 29.

[0042] The arc-shaped cover 2 has a lifting assembly inside, which includes a lifting hook 10. The lifting assembly includes a lifting crossbar 33 fixedly mounted on an adjusting plate 12. A U-shaped pressure rod 34 is fixedly mounted at the end of the lifting crossbar 33 away from the adjusting plate 12. Symmetrically arranged toothed blocks 35 are fixedly mounted on the inner side of the U-shaped pressure rod 34. A through groove 36 is opened on the upper surface of the arc-shaped cover 2. Symmetrically arranged lifting frame plates 37 are fixedly mounted on the inner top of the arc-shaped cover 2. A lifting shaft 38 is fixedly mounted on the lifting frame plate 37. Lifting gears 39 are fixedly mounted on the lifting shaft 38 and inside the two lifting frame plates 37. The U-shaped pressure rod 34... The toothed block assembly 35 meshes with the lifting gear 39 through the through groove 36 extending to the inner side of the arc-shaped cover 2. The lifting hook 10 is fixedly installed on the lifting shaft 38 and is located inside the two lifting gears 39. After the crab is tied up, the pressing block 9 is returned to its original position by the hydraulic cylinder 8. At the same time, by the continuous descent of the adjusting plate 12, the pressing block 9 located on the front side of the arc-shaped cover 2 will rotate to both sides of the arc-shaped cover 2 so that it will not affect the lifting hook 10 from lifting the crab out of the holding block 3. When the lifting hook 10 is not working, it is attached to the inner top of the arc-shaped cover 2 and will not affect the tying machine's tying of the crab.

[0043] In this embodiment, the electric push rod 11 drives the adjusting plate 12 to continuously descend. The lifting crossbar 33 on the adjusting plate 12 drives the U-shaped pressure rod 34 to pass through the through groove 36 and descend to the inner side of the arc-shaped cover 2. The tooth block group 35 meshes with the lifting gear 39. The lifting gear 39 drives the lifting hook 10 to rotate through the lifting shaft 38. During the continuous rotation of the lifting hook 10, the lifting hook 10 hooks onto the rope tied to the crab. Through the continuous rotation of the lifting hook 10, the crab in the holding block 3 can be effectively rotated to the entrance of the arc-shaped cover 2. Through the function of the lifting hook 10, it is convenient for personnel to take out the tied crab from the holding block 3, effectively improving the use effect of the binding machine.

[0044] Working principle: During use, the lifting cylinder 56 is activated according to the size of the crab. The lifting cylinder 56 drives the feeding tube 59 on the lifting frame plate 57 to adjust its position, ensuring that the binding rope delivered by the feeding tube 59 is appropriately positioned for the crab. After the position of the feeding tube 59 is adjusted, the crab is placed in the holding block 3. The binding motor 41 drives the binding shaft 42 to rotate, and the lower bevel gear 53 on the binding shaft 42 rotates. The lower bevel gear 53 meshes with the upper bevel gear 52. The connecting drum 51 on the upper bevel gear 52 drives the worm gear 55 on the connecting vertical rod 54 to rotate through the engagement of the vertical groove 60 and the vertical block 61. Through the engagement of the worm gear 55 and the worm wheel 48, the worm wheel 48 drives the feeding wheel 47 on the feeding shaft 46 to rotate. The binding rope in the feeding tube 59 is conveyed. The rotation of the feeding tube 59 on the mounting plate 43 and the rotation of the feeding wheel 47 ensure that the binding rope on the crab is at a suitable tension, thus avoiding damage caused by excessive tightness or detachment caused by excessive looseness. During the binding process, the electric push rod 11 drives the adjusting plate 12 to a suitable position. The push rod 13 on the adjusting plate 12 moves synchronously. The push rod 13 cooperates with the arc-shaped toothed plate 15, which is then limited by the arc-shaped slider 16 and the arc-shaped groove 17, thus moving to both sides on the arc-shaped cover 2. The arc-shaped toothed plate 15 meshes with the adjusting gear 20. When the adjusting gear 20 rotates, it drives the driving gear 21 to rotate via the rotating shaft 19. The engagement of wheel 21 with outer arc toothed plate 25 causes the outer arc toothed plate 25 to drive the pressing block 9 to adjust its left and right position via connecting crossbar 6. The synchronous adjustment of the two pressing blocks 9 ensures the stability of the crab in the holding block 3 after it has been placed in its fixed position, eliminating the need for manual pressing and avoiding the uncertainty and potential risks associated with manual pressing, thus improving the safety of the crab binding process. When the position of the pressing block 9 needs to be adjusted forward or backward, the electric push rod 11 continuously drives the adjusting plate 12 to descend. When the adjusting plate 12 descends to the appropriate position, the hydraulic cylinder 8 moves from the first sliding surface 31 of the arc-shaped baffle 30 to the second sliding surface 32. When the hydraulic cylinder 8 contacts the second sliding surface 32... At this time, the hydraulic cylinder 8 rotates inward around the flipping rod 28 by the torque of the torsion spring 40 on the flipping block 29. Simultaneously, the hydraulic cylinder 8 drives the pressing block 9 to adjust its position, effectively adjusting the position of the pressing block 9 on the crab, further improving the binding effect. The electric push rod 11 drives the adjusting plate 12 to continuously descend. The lifting crossbar 33 on the adjusting plate 12 drives the U-shaped pressure rod 34 through the through slot 36 and down to the inside of the arc-shaped cover 2. The toothed block assembly 35 meshes with the lifting gear 39, which drives the lifting hook 10 to rotate via the lifting shaft 38. During the continuous rotation of the lifting hook 10, it hooks onto the rope binding the crab. Through the continuous rotation of the lifting hook 10…This machine can effectively rotate the crabs in holding block 3 to the entrance of the arc-shaped cover 2. By lifting the hook 10, it is convenient for personnel to remove the tied crabs from holding block 3, effectively improving the efficiency of the binding machine.
