Technical Field

[0001] The invention belongs to the technical field of bundling auxiliary packaging, in particular to a bundling auxiliary packaging device. Background Art

[0002] With the improvement of people's living standards, the demand for crabs and other seafood products continues to increase, especially in some big cities, crabs have become a very popular seafood product. This growth in demand has led to the emergence of crab strapping machines.

[0003] The crab is then placed in a bundling slot and the strapping machine is started. The strapping tape is first wrapped around the crab's legs for several turns to secure the crab's legs. The strapping slot is then rotated ninety degrees and the strapping tape is continued to be wrapped around the crab's body. After the strapping is completed, the strapping machine uses a nailing machine to fix the two ends of the strapping tape together. The strapping tape is then cut to complete the bundling process of a single crab. However, there are still some problems with the above-mentioned strapping machine in actual use. After the crab's claws and legs are rolled inward and placed in the strapping slot and the crab is released, the strapping tape has not yet been tied.

[0018] The beneficial effects of the present invention are as follows:

[0042] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0043] like Figures 1 to 10As shown, a bundling auxiliary packaging device according to an embodiment of the present invention includes a workbench 1, a connecting tube 11 is fixedly connected to the upper surface of the workbench 1, a fixed platform 2 is fixedly connected to the middle of the workbench 1, a connecting platform 3 is fixedly connected to one side of the fixed platform 2, and a plurality of limit blocks 31 are rotatably provided on the upper surface of the connecting platform 3. An annular groove 12 is provided inside the workbench 1, and a rotating column 13 is rotatably connected in the annular groove 12. The rotating column 13 is used to drive the bundling belt for bundling. An annular frame 14 is fixedly connected to one side of the workbench 1, and the annular frame 14 is used to protect To move the rotating column 13, base plates 32 are fixedly connected on both sides of the fixed platform 2, and a rotating groove 33 is opened at the position of each base plate 32 corresponding to the annular groove 12. A transverse limiter is fixedly connected to the upper surface of the fixed platform 2, and the transverse limiter includes two guide rail grooves 21 opened on the upper surface of the fixed platform 2; a connecting plate 22 slidably connected to each guide rail groove 21, and an auxiliary clamp 23 is fixedly connected to the side where the two connecting plates 22 are close to each other; it also includes a longitudinal limiter fixed on the upper surface of the fixed platform 2, and a rubber band assembly is also provided on the upper surface of the connecting platform 3.

[0044] The crab is then placed in a bundling slot, and the bundling machine is started. The bundling tape is first wound around the crab's legs for several turns to secure the crab's legs. The bundling slot is then rotated ninety degrees, and the bundling tape is then wound around the crab's body. After bundling is complete, the bundling machine uses a nailing machine to fix the two ends of the tape together. The tape is then cut, completing the bundling process of a single crab. However, the above-mentioned bundling machine still has some problems in actual use. After the crab's claws and legs are rolled inward and placed in the bundling slot, and the crab is released, the tape has not yet been tied. If the crab extends its claws, the bundling tape will fail to be tied, and the tied crab claws will be stretched out. The crab claws may also be damaged by the automatic bundling of the machine, resulting in a problem of low bundling quality.

[0045] Therefore, the present invention solves this problem by setting a corresponding structure. First, the crab is placed on the fixed platform 2. After placing it on the fixed platform 2, the connecting plate 22 in the two guide grooves 21 on the upper surface of the fixed platform 2 is started. The connecting plate 22 is electrically connected to the guide groove 21, so that the guide groove 21 can control the connecting plate 22 to slide, and then the two connecting plates 22 are made to slide toward each other. The two connecting plates 22 sliding toward each other will gradually approach the crab with the auxiliary clamps 23 fixed at one end close to each other, and each auxiliary clamp 23 is made of rubber, so as to limit and clamp the crab placed on the fixed platform 2. After the crab is limited and clamped, the longitudinal limit piece is started to limit the crab, and then the rubber band assembly is started to clamp the joints of the two claws of the curled crab. The rubber band is put on the joint of the crab, which can limit the extension of the crab claws. Then the longitudinal limiter is started again, so that the longitudinal limiter pushes the crab with the crab claws wrapped by the rubber band into the several limit blocks 31 on the connecting platform 3. Then the rotating column 13 rotating around the annular groove 12 inside the workbench 1 is started to tie the crab. First, the crab claws are tied, and then the several limit blocks 31 are rotated so that the several limit blocks 31 drive the internally tied crab to rotate ninety degrees. Then the rotating column 13 is started again to tie the crab body. After the tying is completed, the tying machine uses the internal nailing machine to fix the two ends of the tying belt together. Then the tying belt is cut off, completing the tying process of a single crab, thereby protecting the crab claws and improving the quality of tying.

[0046] The invention solves the problem that during the bundling process, the crab's claws and legs are rolled inward and placed in the bundling groove, and after the crab is released, the bundling fails because the bundling belt has not yet been used. If the crab extends its claws, the bundling belt will fail to be tied, and the tied crab claws will be stretched out. The mechanical automatic bundling may also damage the crab claws, resulting in low bundling quality.

[0047] like Figure 4 As shown, in this embodiment, a plurality of limit blocks 31 are distributed in a circular array, a common convex limit groove 34 is provided in the middle of the plurality of limit blocks 31 , and a positioning groove 35 is provided between every two limit blocks 31 .

[0048] Specifically, after the longitudinal limiting member pushes the crab with its claws wrapped in the rubber band to the convex limiting groove 34 inside the limiting block 31, a positioning groove 35 is opened between every two limiting blocks 31. The positioning groove 35 enables the binding belt driven by the rotating column 13 to pass through the positioning groove 35 to bind the crab. At the same time, the convex limiting groove 34 in the limiting block 31 can also limit the crab to a certain extent, thereby achieving a better bundling effect.

[0049] like Figure 4 and Figure 7As shown, the longitudinal limiting member of this embodiment includes a first hydraulic cylinder 24 fixed to the upper surface of the fixing platform 2 , and a positioning plate 242 is fixed to the output end of the first hydraulic cylinder 24 .

[0050] Specifically, in the process of using the longitudinal limiter to limit the crab, the first hydraulic cylinder 24 fixed on the fixed platform 2 drives the positioning plate 242 in its output end to limit the crab, and the cross-section of the positioning plate 242 is "L"-shaped, so as to achieve the longitudinal limitation of the crab, making it impossible for the crab to stand, and then the auxiliary clamps 23 on both sides can limit it longitudinally, so that it cannot move during the process of putting on the rubber band, and the effect of putting on the rubber band can be stabilized.

[0051] like Figure 7 As shown, the upper surface of the positioning plate 242 of this embodiment is provided with two second grooves 241, each of which is fixed with a telescopic column, and the ends of the two telescopic columns away from each other are fixed with an arc plate 245, and a first compression spring 244 is sleeved on the circumferential surface of the telescopic column.

[0052] Specifically, when the positioning plate 242 approaches the crab, since the sizes of crabs are not uniform, in the process of longitudinally limiting the crab, two second grooves 241 are opened on the upper surface of the positioning plate 242. Then, after the positioning plate 242 approaches the crab, the arc plate 245 slidingly arranged in the second groove 241 of the positioning plate 242 can be squeezed laterally by the crab, so that the arc plate 245 will drive the telescopic column in the second groove 241 to move, and at the same time drive the first compression spring 244 on the circumferential surface of the telescopic column to be stretched, thereby achieving the effect of being able to adapt to the crab, and being able to better adapt to the body shape of the crab, making it easier to limit it. Example

[0053] like Figures 2 to 10 As shown, in contrast to Example 1, another embodiment of the present invention is: the rubber band assembly includes two second hydraulic cylinders 25 fixedly connected to the upper surface of the connecting platform 3, and the two second hydraulic cylinders 25 are placed at an angle for aligning with the joints of the crab, and the output end of each second hydraulic cylinder 25 is fixedly connected to a connecting block 251, and one side of each connecting block 251 is slidably connected to two spring pieces 252.

[0054] Specifically, when the crab is limited and a rubber band is needed, the second hydraulic cylinder 25 placed at an angle on the upper surface of the connecting platform 3 is started, and then the second hydraulic cylinder 25 will drive the connecting block 251 at its output end to gradually approach the limited crab. At this time, the crab is in a curled up state, and the two crab claws will contract so that their joints face outward. Therefore, the rubber band stretched on the two spring pieces 252 can be used to bind the joints of the crab claws, so that the crab claws can no longer be extended, thereby improving the efficiency and quality of crab bundling.

[0055] like Figure 5 As shown, in this embodiment, each connecting plate 22 is connected to a first guide rod 27, and the first guide rod 27 is "L"-shaped. A first cavity 28 is provided at a position corresponding to the first guide rod 27 of the fixed platform 2. Two first grooves 210 are provided in the middle of the first cavity 28. The bottom end of each first groove 210 is fixedly connected to a second compression spring 29, and the top end of each second compression spring 29 is fixedly connected to a conical column 211.

[0056] Specifically, when the connecting plate 22 drives the auxiliary clamp 23 to limit the crab, the connecting plate 22 will simultaneously drive the first guide rod 27 connected to it to slide along the guide rail groove 21, and then one end of the first guide rod 27 will be inserted into the first cavity 28, and the first guide rails 4 on both sides will simultaneously squeeze the air in the first cavity 28, so that the cone columns 211 in the two first grooves 210 are squeezed out of the first grooves 210. The cone columns 211 cannot be separated from the first grooves 210 due to the second compression spring 29 fixed to the bottom end, and the two cone columns 211 will squeeze the crab's joints outward after being pushed out. The setting of the cone columns 211 is suitable for the state of most crabs when they are curled up, and then it can assist the rubber band assembly in putting on the rubber band.

[0057] like Figure 10 As shown, the top wall of the workbench 1 in this embodiment is fixedly connected with a first guide rail 4, the lower surface of the first guide rail 4 is provided with a sliding groove 41, a sliding block 42 is slidably connected in the sliding groove 41, the lower surface of the sliding block 42 is fixedly connected with a third hydraulic cylinder 43, the output end of the third hydraulic cylinder 43 is fixedly connected to a limiting rod 44, one end of the limiting rod 44 is fixedly connected to two limiting clamps 45, and the two limiting clamps 45 are both controlled by an air pump.

[0058] Specifically, after the crab's claws are covered by the rubber band assembly, the first guide rail 4 is started to drive the sliding block 42 in the sliding groove 41 on its lower surface to move above the crab. The movement of the sliding block 42 can drive the third hydraulic cylinder 43 to move above the crab, and then the third hydraulic cylinder 43 is started to drive the two limiting clamps 45 on the limiting rod 44 at its output end to move toward the crab, and at the same time the limiting clamps 45 are opened, and then the crab with the covered claws is clamped, and there is no need to push the crab into the limiting groove 34 through the positioning plate 242 at the output end of the first hydraulic cylinder 24 to prevent the crab's legs from being damaged during the pushing process.

[0059] like Figure 10 As shown, the cross-section of the two limiting clamps 45 of this embodiment is spoon-shaped and is used to clamp and limit the crab.

[0060] Specifically, after the two limiting clamps 45 clamp the crab, because the cross-section of the two limiting clamps 45 is spoon-shaped, when the limiting clamps 45 are placed in the limiting groove 34, because the limiting groove 34 is convex, the limiting clamps 45 can extend into the wider part of the limiting groove 34. After the crab legs are tied, the limiting clamps 45 are loosened and separated from the crab, and then several limiting blocks 31 can rotate, driving the crab to rotate ninety degrees, and then the body is tied, achieving a pressing effect.

[0061] like Figure 4 and Figure 9 As shown, the upper surface of the connecting table 3 of this embodiment is rotatably connected to two sealing plates 26, one end of each sealing plate 26 is rotatably connected to a fixed shaft 261, and the circumferential surface of the fixed shaft 261 is sleeved with a torsion spring 262, and the workbench 1 is clamped with a collection box 5 below the two sealing plates 26.

[0062] Specifically, after the crabs are bundled, the limited clamp 45 is started again to clamp the bundled crabs, and then the sliding block 42 is started to move along the sliding groove 41 to above the two sealing plates 26. At this time, the third hydraulic cylinder 43 is started again to drive the limited clamp 45 to press against the sealing plate 26, so that the sealing plate 26 rotates, and the limited clamp 45 is released, so that the crabs in the limited clamp 45 fall into the collection box 5, achieving the effect of automatic collection.

[0063] like Figure 6 As shown, two clamping blocks 51 are fixedly connected to one side of the workbench 1 of this embodiment, and the surfaces of the two clamping blocks 51 are clamped with a collection box 5. A collection groove 52 is opened inside the collection box 5, and a collection frame 53 is clamped in the middle of the collection groove 52. The lower surface of the collection frame 53 is fixed with an elastic net 54.

[0064] Specifically, when the crabs fall into the collection box 5, they will fall into the collection frame 53 that is locked in the collection box 5, and the bottom surface of the collection frame 53 is fixed with an elastic net 54, thereby protecting the crabs from falling and preventing the crab legs from being damaged during the falling process, thereby achieving the effect of packaging crabs with higher quality.

[0065] The working principle is as follows: first, place the crab on the fixed platform 2. After placing it on the fixed platform 2, start the connecting plate 22 in the two guide grooves 21 on the upper surface of the fixed platform 2. The connecting plate 22 is electrically connected to the guide groove 21, so that the guide groove 21 can control the connecting plate 22 to slide, and then make the two connecting plates 22 slide toward each other. The two connecting plates 22 sliding toward each other will gradually approach the crab with the auxiliary clamps 23 fixed at one end close to each other, and each auxiliary clamp 23 is made of rubber, thereby limiting the crab placed on the fixed platform 2. The connecting plate 22 will simultaneously drive the first guide rod 27 connected to it to slide along the guide groove 21, and then one end of the first guide rod 27 will be inserted into the first cavity 28, and the first guide rails 4 on both sides will simultaneously squeeze the air in the first cavity 28, so that the cone columns 211 in the two first grooves 210 are squeezed out of the first groove 210, and the cone columns 211 cannot fall out due to the second compression spring 29 fixed at the bottom end. The crab is separated from the first groove 210, and the two cone columns 211 are pushed out to squeeze the crab's joints outward. The setting of the cone column 211 is suitable for the state when most crabs are curled up. Then, by starting the first hydraulic cylinder 24 fixed on the fixed platform 2, the positioning plate 242 in its output end is driven to limit the crab. The cross section of the positioning plate 242 is "L"-shaped, so that the crab can be limited in the longitudinal direction, making it impossible for the crab to stand. In the process of longitudinally limiting the crab, two second grooves 241 are provided on the upper surface of the positioning plate 242. Then, after the positioning plate 242 approaches the crab, the arc plate 245 slidingly arranged in the second groove 241 of the positioning plate 242 can be squeezed laterally by the crab, so that the arc plate 245 will drive the telescopic column in the second groove 241 to move, and at the same time drive the first compression spring 244 on the circumferential surface of the telescopic column to be stretched, thereby achieving the effect of being able to adapt to the crab and being able to better adapt to the crab for limiting.

[0066] Then, by starting the second hydraulic cylinder 25 placed at an angle on the upper surface of the connecting platform 3, the second hydraulic cylinder 25 will drive the connecting block 251 at its output end to gradually approach the restricted crab. At this time, the crab is in a curled-up state, and the two crab claws will shrink so that their joints face outward. Therefore, the rubber bands stretched on the two spring pieces 252 can bind the joints of the crab claws, so that the crab claws can no longer be extended. After the rubber bands are put on the joints of the crab, the extension of the crab claws can be restricted. After the crab claws are covered with the rubber band assembly, the first guide rail 4 is started to drive the sliding block 42 in the sliding groove 41 on its lower surface to move above the crab. The movement of the sliding block 42 can drive the third hydraulic cylinder 43 to move above the crab, and then the third hydraulic cylinder 43 is started. , so that it drives the two limiting clamps 45 on the limiting rod 44 at its output end to move toward the crab, and at the same time makes the limiting clamps 45 open, and then clamps the crab with the clamps, and there is no need to push the crab into the limiting groove 34 through the positioning plate 242 at the output end of the first hydraulic cylinder 24, to prevent the crab's legs from being damaged during the pushing process. After the two limiting clamps 45 clamp the crab, because the cross-section of the two limiting clamps 45 is spoon-shaped, when the limiting clamps 45 are placed in the limiting groove 34, because the limiting groove 34 is convex, the limiting clamps 45 can extend into the wider part of the limiting groove 34, after the crab legs are tied, the limiting clamps 45 are loosened and separated from the crab, and then the several limiting blocks 31 can rotate, driving the crab to rotate ninety degrees, and then the body is tied, achieving a pressing effect;

[0067] After bundling is completed, the bundling machine uses an internal nailing machine to fix the two ends of the bundling tape together, and then the bundling tape is cut off, completing the bundling process of a single crab, achieving the protection of the crab bundling and improving the bundling quality;

[0068] After the crabs are bundled, the limited clamp 45 is started again to clamp the bundled crabs, and then the sliding block 42 is started to move along the sliding groove 41 to above the two sealing plates 26. At this time, the third hydraulic cylinder 43 is started again to drive the limited clamp 45 to press against the sealing plate 26, so that the sealing plate 26 rotates, and the limited clamp 45 is released, so that the crabs in the limited clamp 45 fall into the collection box 5, achieving the effect of automatic collection. When the crabs fall into the collection box 5, they will fall into the collection frame 53 that is clamped in the collection box 5, and the bottom surface of the collection frame 53 is fixed with an elastic net 54, thereby protecting the crabs from falling and preventing the crab legs from being damaged during the falling process, thereby achieving the effect of packing higher quality crabs.
