Description

Technical Field

[0001] This invention relates to the field of fresh food processing technology, specifically to a hairy crab binding machine and binding method. 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] Furthermore, the hairy crabs need to be tied up before packaging because crabs will sever their limbs to survive. If they are not tied up, the bumps during transportation will cause the hairy crabs to sever their limbs. However, the existing technology for tying hairy crabs is all done manually, which is time-consuming, labor-intensive, and inefficient. Therefore, we propose a hairy crab tying machine and tying method. Summary of the Invention

[0010] Preferably, the wire-removing mechanism includes a second fixed frame, a third roller, a second movable plate, a connecting frame, and a pushing claw.

Two sets of cutting scissors are fixedly connected to the output end of the finger cylinder at a position corresponding to the knotting mechanism.

[0014] Preferably, a method for binding hairy crabs using a binding machine includes the following steps:

[0015] Step 1: Place the crabs to be tied inside the holding block, then pass the thread through the inside of the thread feeding tube and place it on the outer surface of the positioning roller. Then start the second motor to drive the thread feeding tube to rotate, and the thread bundle rotates along the rope groove, thus completing the first step of tying the crabs inside the holding block. Then start the first motor to make the crabs inside the holding block rotate. Then the second motor continues to rotate, thus completing the second step of tying the crabs.

[0016] Step 2: After the hairy crabs are tied up, start the third motor. The third motor can drive the first drive rod and the fixed roller to rotate. At this time, the rotation of the fixed roller drives the third drive block to rotate. Then the third drive block can push the third roller and the second fixed frame to rotate. At this time, the second fixed frame can be used to push the second moving plate and the pushing claw to move, thereby pushing the wire harness to move.

[0017] Step 3: When the fixed roller rotates, it drives the first drive block to rotate. At this time, the first roller is located between the fixed roller and the first drive block. Then, the fixed roller continues to rotate, which drives the second mounting bracket to a vertical state. The wire harness pushed by the push claw can then move to the position between the first clamping claw and the second clamping claw. The vertical second mounting bracket can then make the gear block mesh with the first worm gear. At this time, the rotation of the first worm gear and the second worm gear can drive the third worm gear and the second rotating shaft to rotate. The second rotating shaft can drive the first clamping claw and the second clamping claw to rotate. Because of the squeezing guide of the second drive rod, the first clamping claw and the second clamping claw can be in a state of first closing, then opening and then closing again. In this way, the first clamping claw and the second clamping claw can be used to knot the wire harness. After the knotting is completed, the fixed roller continues to rotate, which can disengage the first drive block from the first roller. Then, the second mounting bracket can be restored to the tilted state.

[0018] Step 4: During the knotting process, the cylinder pushes the rotating rod and the rope-pulling claw to rotate, and then the rope-pulling claw pushes the wire harness on the outer surface of the positioning roller to move towards the positions of the first clamping claw and the second clamping claw.

[0019] Step 5: After the knot is tied, the pneumatic slider and the pneumatic slide rail move relative to each other, thereby moving the finger cylinder and the cutting scissors to the position of the wire harness. Then the finger cylinder operates to drive the two sets of cutting scissors to cut the wire harness.

[0020] Step Six: When the second mounting frame retracts, the rotation of the fixed roller can drive the second drive block to contact the second roller. Then the second roller follows the second drive block to move, so that the first fixed frame and the first hinge rod can be used to push the first moving plate and the feeding rod to move towards the surface of the first clamping claw and the second clamping claw. Then the retracted first clamping claw and the second clamping claw can contact the feeding rod, thereby completing the untying step. After the untying is completed, the hairy crabs inside the holding block are tied up.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This invention can automate the binding process of hairy crabs, avoiding excessive manual intervention. This binding method improves the production efficiency of hairy crabs to a certain extent and avoids the possibility of worker injury caused by traditional binding methods.

[0023] 2. The placement mechanism can support the crab, and the winding mechanism can wrap the wire harness around the crab. The placement mechanism can also rotate the crab, thus completing the all-around binding of the crab. The drive mechanism can move towards the knotting mechanism using the wire pushing mechanism. The rotation of the drive mechanism can then move the knotting mechanism, thus completing the knotting process of the wire harness. After knotting, the cutting mechanism can cut the wire harness, and the untying mechanism can remove the wire harness from the knotting mechanism, thus completing the binding process of the crab. This crab binding device can complete the knotting, pushing, and untying steps of the crab using only one power source, saving a significant amount of energy. Attached Figure Description

[0047] Example 2:

[0048] A method for binding hairy crabs using a binding machine includes the following steps:

[0049] Step 1: Place the crabs to be tied inside the holding block 13, then pass the yarn 60 through the inside of the feeding tube 20 and place it on the outer surface of the positioning roller 62. Then start the second motor 17 to drive the feeding tube 20 to rotate, and the yarn bundle rotates along the rope groove 16, thus performing the first step of tying the crabs placed inside the holding block 13. Then start the first motor 14 to rotate the crabs inside the holding block 13. Then the second motor 17 continues to rotate, thus performing the second step of tying the crabs.

[0050] Step 2: After the hairy crabs are tied up, start the third motor 22. The third motor 22 can drive the first drive rod 23 and the fixed roller 24 to rotate. At this time, the rotation of the fixed roller 24 drives the third drive block 27 to rotate. Then the third drive block 27 can push the third roller 53 and the second fixed frame 52 to rotate. At this time, the second fixed frame 52 can be used to push the second moving plate 54 and the pushing claw 56 to move, thereby pushing the wire harness to move.

[0051] Step 3: When the fixed roller 24 rotates, it drives the first drive block 25 to rotate. At this time, the first roller 39 is located between the fixed roller 24 and the first drive block 25. Subsequently, the fixed roller 24 continues to rotate, which drives the second mounting bracket 30 to a vertical state. Then, the wire harness pushed by the push claw 56 can move to the position between the first clamping claw 36 and the second clamping claw 38. Then, the vertical second mounting bracket 30 can make the gear block 29 mesh with the first worm gear 32. At this time, the rotation of the first worm gear 32 and the second worm gear 33 can drive the third worm gear 33. The wheel 35 and the second rotating shaft 34 rotate, and the second rotating shaft 34 can drive the first clamping claw 36 and the second clamping claw 38 to rotate. Because of the squeezing guide of the second drive rod 37, the first clamping claw 36 and the second clamping claw 38 can be in a state of first closing, then opening and then closing again. In this way, the first clamping claw 36 and the second clamping claw 38 can be used to knot the wire harness. After the knotting is completed, the fixed roller 24 continues to rotate, which can disengage the first drive block 25 from the first roller 39. Then the second mounting bracket 30 can be restored to the tilted state.

[0052] Step 4: During the knotting process, cylinder 57 pushes rotating rod 58 and rope-pulling claw 59 to rotate. Then, rope-pulling claw 59 pushes the wire harness on the outer surface of positioning roller 62 to move towards the position of first clamping claw 36 and second clamping claw 38.

[0053] Step 5: After the knot is tied, the pneumatic slider 42 and the pneumatic slide rail 43 move relative to each other, thereby moving the finger cylinder 45 and the cutting scissors 46 to the wire harness position. Then the finger cylinder 45 operates to drive the two sets of cutting scissors 46 to cut the wire harness.

[0054] Step Six: When the second mounting bracket 30 retracts, the rotation of the fixed roller 24 can drive the second drive block 26 to contact the second roller 48. Then the second roller 48 moves with the second drive block 26, so that the first fixed bracket 47 and the first hinge rod 50 can push the first moving plate 49 and the feeding rod 51 to move towards the surface of the first clamping claw 36 and the second clamping claw 38. Then the retracted first clamping claw 36 and the second clamping claw 38 can contact the feeding rod 51, thereby completing the untying step. After the untying is completed, the hairy crabs inside the holding block 13 are tied up.

[0055] Example 3;

[0056] Please see Figure 10 The binding knot of the wire harness is located above the crab and in the middle of the two crab horns. The crab is bound by mechanically tying a slipknot using this device, which simulates manually wrapping the rope twice and then tying a slipknot to secure it. Moreover, the tension of the binding rope harness can be adjusted by an external tensioning wheel, so that crabs of any size can be bound.

4. A binding method for a hairy crab binding machine according to any one of claims 1-3, characterized in that: The binding method of the aforementioned hairy crab binding machine includes the following steps: Step 1: Place the crabs to be tied inside the holding block (13), then pass the yarn (60) through the inside of the thread feeding tube (20) and place it on the outer surface of the positioning roller (62). Then start the second motor (17) to operate. The second motor (17) drives the thread feeding tube (20) to rotate, and the yarn bundle rotates along the rope groove (16) to perform the first step of tying the crabs placed inside the holding block (13). Then start the first motor (14) to operate, so that the crabs inside the holding block (13) rotate. Then the second motor (17) continues to rotate to perform the second step of tying the crabs. Step 2: After the hairy crabs are tied up, start the third motor (22). The third motor (22) drives the first drive rod (23) and the fixed roller (24) to rotate. At this time, the rotation of the fixed roller (24) drives the third drive block (27) to rotate. Then the third drive block (27) pushes the third roller (53) and the second fixed frame (52) to rotate. At this time, the second fixed frame (52) can be used to push the second moving plate (54) and the push claw (56) to move, thereby pushing the wire harness to move. Step 3: When the fixed roller (24) rotates, it drives the first drive block (25) to rotate. At this time, the first roller (39) is located between the fixed roller (24) and the first drive block (25). Then, the fixed roller (24) continues to rotate, driving the second mounting bracket (30) to a vertical state. Then, the wire harness pushed by the push claw (56) moves to the position between the first clamping claw (36) and the second clamping claw (38). Then, the vertical second mounting bracket (30) causes the gear block (29) to mesh with the first worm gear (32). At this time, the rotation of the first worm gear (32) and the second worm gear (33) drives the first drive block (25) to rotate. The three worm gears (35) and the second shaft (34) rotate. The second shaft (34) drives the first clamping claw (36) and the second clamping claw (38) to rotate. Due to the squeezing guide of the second drive rod (37), the first clamping claw (36) and the second clamping claw (38) are in a state of first closing, then opening and then closing again. The first clamping claw (36) and the second clamping claw (38) can be used to knot the wire harness. After the knotting is completed, the fixed roller (24) continues to rotate, causing the first drive block (25) to disengage from the first roller (39). Then the second mounting bracket (30) is restored to the tilted state. Step 4: During the knotting process, the cylinder (57) pushes the rotating rod (58) and the rope-pulling claw (59) to rotate. Then the rope-pulling claw (59) pushes the wire harness on the outer surface of the positioning roller (62) to move to the positions of the first clamping claw (36) and the second clamping claw (38). Step 5: After the knot is tied, the pneumatic slider (42) and the pneumatic slide rail (43) move relative to each other, thereby moving the finger cylinder (45) and the cutting scissors (46) to the wire harness position. Then the finger cylinder (45) operates to drive the two sets of cutting scissors (46) to cut the wire harness. Step 6: When the second mounting bracket (30) retracts, the rotation of the fixed roller (24) drives the second drive block (26) to contact the second roller (48). Then the second roller (48) moves with the second drive block (26), thereby using the first fixed bracket (47) and the first hinge rod (50) to push the first moving plate (49) and the feeding rod (51) to move towards the surface of the first clamping claw (36) and the second clamping claw (38). Then the retracted first clamping claw (36) and the second clamping claw (38) contact the feeding rod (51), thereby completing the unwinding step. After the unwinding is completed, the hairy crabs inside the holding block (13) are tied up.
