Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture equipment, and in particular relates to a seedling cloth conveying device for an automatic mussel seedling wrapping machine. Background Art

[0002] Common shellfish seafood mainly include: clams, razor clams, scallops, oysters, and mussels. Among them, the method of cultivating mussels generally includes the following steps in sequence:

[0003] First, make breeding rope;

[0004] Second, hang it on the floating rope after launching;

[0005] Third, remove the seedling cloth;

[0006] Fourth, protection and management;

[0007] Fifth, harvesting.

[0008] The function of the above-mentioned automatic mussel seedling wrapping machine is to make aquaculture ropes. The structure of the aquaculture rope mainly includes a seedling rope, a seedling cloth, and mussel seedlings. The common aquaculture rope shape is a thick strip in the middle with one long and one short exposed at both ends. The relatively short exposed end of the seedling rope is the lower end of the aquaculture rope when it is suspended vertically, and the other relatively long exposed end is the upper end, which is used to tie the floating rope.

[0009] On the other hand, whether the culture rope is made manually or by the above-mentioned automatic mussel seedling wrapping machine, the general steps are the same, which mainly include: spreading the seedling cloth, correctly placing the seedling rope, quantitatively placing the mussel seedlings, and sewing the seedling cloth to seal.

[0010] Among them, the following matters need to be explained: First, after the breeding rope is made, since the mussel seedlings can be passively filled and actively moved in the seedling cloth, the seedling rope at the bottom will definitely move to the middle of the above-mentioned thick strip structure during production, becoming the "center line" of the breeding rope, so that all the mussel seedlings have sufficient space for the attachment of byssus threads; second, when the seedling cloth is sewn, it is generally not sewn and fixed together with the seedling rope. The reason is that the difficulty of sewing and removing the cloth will be greatly increased, and it is unnecessary. The relatively crowded filling amount of mussel seedlings in the seedling cloth is enough to generate a large friction between the seedling rope and the mussel seedlings, and the mussel seedlings will not fall down even before the byssus threads grow.

[0011] In addition, the common seedling cloth conveying device mentioned above mainly comprises a conveying roller / belt, a sewing mechanism, and a cutting mechanism, so that the seedling cloth can be closed and sealed and obtain an appropriate length, ensuring that both ends of the seedling rope are fully exposed.

[0012] For example, a Chinese utility model patent with authorization announcement number CN210352702U and authorization announcement date 2020.04.21 discloses a mussel seed wrapping machine, including a frame, with a hemp rope winch and a culture seedling rope winch at both ends of the frame respectively, and a base is also provided on the frame, and an annular ring one and annular ring two that can rotate circumferentially are provided on the base, and a rotary wrapping mesh cloth is provided on the annular ring one and the annular ring two; a seedling wrapping cloth roll and a seedling spreader are provided on the frame between the hemp rope winch and the annular ring one, and a seedling wrapping platform is also provided between the seedling wrapping cloth roll and the annular ring one, and the seedling spreader has a seedling spreading opening facing the seedling wrapping cloth.

[0013] The mussel seed packaging machine in this utility model patent has the following general advantages: it uses mechanical automation to achieve seed packaging, which saves manpower and improves efficiency. The entire process is driven by multiple sets of motors, which can realize the automated operation of mussel seed packaging.

[0014] However, in actual use, the mussel seed packaging machine still has at least the following disadvantages, which are also the technical problems to be solved by the present invention, namely:

[0015] When the seed spreader is placing mussel seed, the seed covering cloth is still laid flat on the seed covering table, so the mussel seed is easy to roll outwards at the side of the seed covering cloth, thereby greatly reducing the quality and efficiency of the seed covering operation.

[0016] Therefore, in summary, there is an urgent need for a new type of conveying device for mussel seedlings which is not easy to fall off the seedling cloth when the mussel seedlings are lowered, so as to be used in various types of automatic mussel seedling packaging machines. Summary of the invention

[0017] The invention provides a seedling cloth conveying device for an automatic mussel seedling wrapping machine, the structural composition of which comprises a conveyor belt for conveying the seedling cloth and the seedling rope together after a seedling rope is introduced onto the upper surface of the seedling cloth, and two guide wheels which are arranged at a position above the conveyor belt and are used to form a U-shaped mussel seedling lowering area below a lowering pipe by clamping two side edges of the seedling cloth that are tilted upward, so that: the seedling cloth area below the lowering pipe is always in a U-shape, ensuring that the mussel seedlings are not easily leaked at the side edges of the seedling cloth during the lowering operation.

[0018] The technical solution adopted by the present invention to solve the above-mentioned problem is: a seedling cloth conveying device for an automatic mussel seedling wrapping machine, the structure of which includes a conveyor belt for conveying the seedling cloth and the seedling rope together after the seedling rope is introduced onto the upper surface of the seedling cloth, and two guide wheels which are arranged above the conveyor belt and are used to form a U-shaped mussel seedling lowering area below the discharge pipe by clamping the two side edges of the seedling cloth that are tilted upward.

[0019] A further preferred technical solution is that it also includes a vertical shaft for installing the guide wheel, a vertical fixed tube for installing the vertical shaft, and a fixed sewing machine arranged on the vertical fixed tube and used for sewing the side edges of the seedling cloth.

[0020] A further preferred technical solution is that it also includes a lifting sewing machine which is arranged above the conveyor belt and behind the fixed sewing machine in the conveying direction of the seedling cloth and is used to sew the ends of the seedling cloth.

[0021] A further preferred technical solution is that it also includes a lifting cutting machine which is arranged above the conveyor belt and in front of the fixed sewing machine in the conveying direction of the seedling cloth and is used for cutting the seedling cloth.

[0022] A further preferred technical solution is that both the lifting sewing machine and the lifting cutting machine are provided with vertical adjustment cylinders.

[0023] A further preferred technical solution is that it also includes a pressure-driving dual-purpose wheel which is arranged above the conveyor belt and behind the lifting sewing machine in the conveying direction of the seedling cloth and is used to convey the seedling rope and press down the seedling cloth.

[0024] A further preferred technical solution is that it also includes an auxiliary conveyor belt whose upper belt body is flush with the conveyor belt and is used to convey the seedling ropes to the upper surface of the seedling cloth.

[0025] A further preferred technical solution is that it also includes a single-seam plate which is arranged below the conveyor belt and is used to lay the wide edge of the seedling cloth on the conveyor belt.

[0026] A further preferred technical solution is that it also includes two pairs of side limit blocks which are arranged below the conveyor belt and are used to lay the wide edges of the seedling cloth on the conveyor belt.

[0027] A method for using a seedling cloth conveying device for an automatic mussel seedling packaging machine comprises the following steps in sequence:

[0028] S1, keep the conveyor belt in a closed state, and first wind the rolled seedling cloth around the feeding end of the conveyor belt from bottom to top, and then clamp the two side edges between the two guide wheels in a way that the side edges are tilted upward;

[0029] S2. Introduce the seedling rope onto the upper surface of the seedling cloth until the end of the seedling rope passes under the guide wheel and is exposed 8-10 cm from the end of the seedling cloth, which serves as the binding end of the breeding rope;

[0030] S3, turning on the lifting sewing machine to form a head end stitch on the seedling cloth;

[0031] S4, turning on the fixed sewing machine, the conveyor belt and the feeding pipe to form side stitches on the seedling cloth, and placing the mussel seedlings between the two raised sides of the seedling cloth;

[0032] S5. When the lateral distance between the rear end of the seedling rope and the feed pipe is 5-6 cm, the feed pipe is turned off. When the lateral distance between the rear end of the seedling rope and the feed pipe is 3-4 cm, the conveyor belt is first turned off, and then the lifting sewing machine is turned on to form a tail end stitch on the seedling cloth;

[0033] S6, turning on the conveyor belt again, and when the side stitching line passes over the tail stitching line, turning off the fixed sewing machine;

[0034] S7. When the tail end of the seedling rope crosses the lifting and cutting machine horizontally, the conveyor belt is first turned off, and then the lifting and cutting machine is turned on to cut the seedling cloth, so that a single breeding rope can be completely produced.

[0049] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0050] As attached Figure 1-11 As shown, a seedling cloth conveying device for an automatic mussel seedling wrapping machine comprises a conveyor belt 1 for conveying the seedling cloth a and the seedling rope b together after the seedling rope b is introduced onto the upper surface of the seedling cloth a, and two guide wheels 2 arranged above the conveyor belt 1 and used to form a U-shaped mussel seedling lowering area below a discharge pipe c by clamping two side edges of the seedling cloth a tilted upward.

[0051] In this embodiment, the conveyor belt 1 is used together with a stepper motor because the conveyor belt 1 needs to be frequently started and stopped during use. When a roll of seedling cloth a is first used on the conveying device, the operator needs to manually clamp the raised end of the side between the two guide wheels 2, and the specific method is as follows:

[0052] The unwinding end of the seedling cloth a is folded upward and hung between the two guide wheels 2 with half the width to form a U-shaped mussel seedling lowering area. The U-shaped structure starts from the roller shaft of the winding conveyor belt of the seedling cloth a to the guide wheel 2, and the height and the U-shaped bending amplitude continuously increase, and finally a continuously changing U-shaped structure is formed on the seedling cloth a.

[0053] Accordingly, the closer the U-shaped structure is to the roller shaft at the feeding end of the conveyor belt 1, the smaller the depth of the U-shaped structure is, and the worse the effect of preventing the mussel seedlings from falling out on both sides when being lowered. Therefore, the lateral distance between the guide wheel 2 and the discharge pipe c should not be too large, and the U-shaped depth of the mussel seedling lowering area directly below the discharge pipe c is at least 3-4 cm.

[0054] On the other hand, when the guide wheel 2 is clamped and suspended to form the U-shaped mussel seedling lowering area, the bottom of the seedling cloth a only falls on the conveyor belt 1. At this time, if the conveyor belt 1 is turned on, it only runs idle and cannot transport the seedling cloth a forward.

[0055] Therefore, the conveying device obtains pressure from the seedling rope loading action which is indispensable in the seedling wrapping step, so that the seedling rope b presses down the seedling cloth a, and the seedling cloth a presses down the conveyor belt 1, and finally obtains sufficient static friction between the seedling cloth a and the conveyor belt 1, so that the conveyor belt 1 can drive the seedling cloth a, and then convey the seedling cloth a and the seedling rope b forward together, which is very clever and practical.

[0056] At this point, the seedling cloth a can cover the seedling rope b and the mussel seedlings together to form the main structure of the breeding rope. In this process, the position below the feeding pipe c is always a continuously generated, deep and constant U-shaped feeding area, which can greatly reduce the probability of the mussel seedlings rolling off the seedling cloth a.

[0057] However, it should be noted that the thick strips of mussel seedlings g formed by continuous lowering need to pass under the two guide wheels 2. Therefore, the height of the guide wheels 2 cannot be too low, otherwise, even if the two sides of the seedling cloth a are greatly bulged and deformed to both sides, the thick strips of mussel seedlings g cannot be allowed to pass smoothly.

[0058] Therefore, correspondingly, the guide wheel 2 can only clamp the relatively small size of the side of the seedling cloth a. For example, the flattened width of the seedling cloth a is 10 cm, the height difference between the guide wheel 2 and the conveyor belt 1 is 4 cm, and the clamping size of the guide wheel 2 on the side of the seedling cloth a is 0.5 cm, so that the U-shaped seedling cloth a can hold more mussel seedlings and ensure that all mussel seedlings can pass under the two guide wheels 2.

[0059] On the other hand, the force with which the two guide wheels 2 clamp the two sides of the seedling cloth a must be relatively large, so that the thick mussel seedlings that are caught cannot pull the seedling cloth a downward from between the two guide wheels 2, otherwise a large number of mussel seedlings will fall out.

[0060] The seedling cloth conveying device also includes a vertical shaft 3 for installing the guide wheel 2, a vertical fixed tube 4 for installing the vertical shaft 3, and a fixed sewing machine 5 arranged on the vertical fixed tube 4 and used for sewing the side edge of the seedling cloth a.

[0061] In this embodiment, the guide wheel 2 is a power wheel, that is, the vertical shaft 3 is externally connected to a driving motor, so that when the conveyor belt 1 conveys the seedling cloth a forward, it is ensured that the guide wheel 2 will not pull the seedling cloth a backward.

[0062] The fixed sewing machine 5 is a commercially available product, for example, a needle-type or laser-type sewing device, which is turned on and off as needed.

[0063] In addition, the structure of the seedling cloth conveying device also includes a bottom plate, a vertical plate, and a plurality of cross bars arranged on the vertical plate, so that the above-mentioned vertical fixed tube 4 and the following structures can be stably and independently installed in appropriate positions.

[0064] Finally, the vertical fixed tube 4 is provided with an axial limit bearing for mounting the vertical shaft 3 , and the fixed sewing machine 5 is arranged on one of the vertical fixed tubes 4 to form a side seam e, the height of which is higher than the guide wheel 2 .

[0065] The seedling cloth conveying device also includes a lifting sewing machine 6 which is arranged above the conveyor belt 1 and behind the fixed sewing machine 5 in the conveying direction of the seedling cloth a and is used for sewing the end of the seedling cloth a.

[0066] In this embodiment, the lifting sewing machine 6 and the fixed sewing machine 5 are the same type of equipment, which are used to form the head end stitch d and the tail end stitch f.

[0067] The seedling cloth conveying device also includes a lifting cutting machine 7 which is arranged above the conveyor belt 1 and in front of the fixed sewing machine 5 in the conveying direction of the seedling cloth a and is used for cutting the seedling cloth a.

[0068] In this embodiment, the lifting and cutting machine 7 is a commercially available product, for example, it can be a laser cutting machine, and its main function is: after a breeding rope is made, the seedling cloth a can be completely cut off, so that the seedling cloth a returns to the initial state of being clamped by the two guide wheels 2 at the beginning.

[0069] Therefore, for a roll of seedling cloth a, it only needs to perform a manual guide wheel clamping operation at the beginning during use, which is very simple and efficient.

[0070] The lifting sewing machine 6 and the lifting cutting machine 7 are both provided with a vertical adjustment cylinder 8 .

[0071] In this embodiment, the two vertical adjustment cylinders 8, like the vertical fixed pipe 4, are stably and independently mounted on the integral frame of the seedling cloth conveying device to ensure that all corresponding functions are effectively performed.

[0072] In addition, the stroke of the vertical adjustment cylinder 8 needs to be relatively large to ensure:

[0073] First, the head end suture d and the tail end suture f are sufficiently close to the seedling rope b to avoid leaving a large opening there, otherwise the mussel seedlings will fall out at the opening;

[0074] Second, the cutting position h can penetrate the entire seedling cloth a downward.

[0075] The seedling cloth conveying device also includes a pressure-driving dual-purpose wheel 9 which is arranged above the conveyor belt 1 and behind the lifting sewing machine 6 in the conveying direction of the seedling cloth a and is used to convey the seedling rope b and press down the seedling cloth a.

[0076] In this embodiment, the simplest and most original way of loading the seedling rope b on the seedling cloth a is to directly place the former on the latter. This method basically does not affect the subsequent seedling wrapping operation, but it also has disadvantages, and at least includes:

[0077] First, the seedling cloth a is relatively light, and its weight can be ignored. Therefore, the source of the static friction between the seedling cloth a and the conveyor belt 1 can only be the weight of the seedling rope b. Therefore, it is relatively easy for the seedling cloth a and the conveyor belt 1 to slip;

[0078] Second, there are multiple structures such as the feeding tube c, the guide wheel 2, the lifting sewing machine 6, the lifting cutting machine 7, etc. above the seedling cloth a. Therefore, the seedling rope b cannot be directly lowered when it is placed, but can only be placed on the seedling cloth a at an angle after avoiding the above structures. It is very troublesome, and the seedling rope b is not easy to keep straight, and it is difficult to obtain a state in which the front end is exposed outside the seedling cloth a.

[0079] Therefore, the pressure-driving dual-purpose wheel 9 can not only indirectly enable the conveyor belt 1 to transport the seedling cloth a stably and without slipping, but also enable the seedling rope b to slide along the length direction of the seedling cloth a for loading, thereby reducing the difficulty of loading.

[0080] It should be noted that when the seedling rope b is introduced and loaded on the upper surface of the seedling cloth a, the latter is stationary, and the sliding friction between the two is relatively small and insufficient to drive the latter to move.

[0081] The seedling cloth conveying device also includes an auxiliary conveyor belt 10 whose upper belt body is flush with the conveyor belt 1 and is used to convey the seedling rope b to the upper surface of the seedling cloth a.

[0082] In this embodiment, the auxiliary conveyor belt 10 and the pressure-driving dual-purpose wheel 9 are used in conjunction, and their function is reflected on the seedling rope b, that is: if there are no two driving structures mentioned above, or only one of them, the conveyor belt 1 may transport the seedling cloth a forward, but the seedling cloth a and the seedling rope b slip, and the seedling rope b still remains in place, which is a harmful phenomenon.

[0083] The auxiliary conveyor belt 10 and the pressure-driving dual-purpose wheel 9 are used in conjunction with each other, and their functions on the seedling cloth a are:

[0084] First, the seedling rope b can fully press down the seedling cloth a through its own weight and the downward pressure transmitted from the pressure-driving dual-purpose wheel 9, so that there is sufficient sliding friction between the seedling cloth a and the conveyor belt 1, ensuring that the conveyor belt 1 can transport the seedling cloth a forward;

[0085] Second, the front end of the seedling rope b is exposed on the seedling cloth a with sufficient and appropriate length, serving as the binding end of the breeding rope connected to the floating rope.

[0086] On the other hand, the feed pipe c is located between the pressure-driving dual-purpose wheel 9 and the guide wheel 2, ensuring that the U-shaped pattern of the area below the feed pipe c of the seedling cloth a has sufficient depth, further preventing the mussel seedlings from falling on the seedling cloth a when being lowered.

[0087] Correspondingly, the minimum depth of the above-mentioned continuous U-shaped pattern is near the roller shaft at the feeding end of the conveyor belt 1 , and the maximum depth is near the guide wheel 2 .

[0088] The seedling cloth conveying device also includes a single-seam plate 11 which is arranged at a position below the conveyor belt 1 and is used to lay the wide edge of the seedling cloth a on the conveyor belt 1.

[0089] In this embodiment, the pressure-driving dual-purpose wheel 9, the auxiliary conveyor belt 10, and the single-slit plate 11 are all installed on the above-mentioned integral frame in the existing common way to ensure that the structure itself is installed stably and operates effectively. Accordingly, the distance between the pressure-driving dual-purpose wheel 9 and the conveyor belt 1 is slightly smaller than the diameter of the seedling rope b, thereby appropriately pressing the seedling rope b, and the single-slit plate 11 itself is horizontal, its horizontal position is located between the conveyor belt 1 and the auxiliary conveyor belt 10, and its vertical position is located between the conveyor belt 1 and the rolled seedling cloth a, ensuring that the former can be completely flattened when the seedling cloth a is first attached to the conveyor belt 1.

[0090] Among them, the length of the gap on the single-seam plate 11 is slightly larger than the width of the seedling cloth a, and the gap width of the former is slightly larger than the thickness of the seedling cloth a.

[0091] The seedling cloth conveying device also includes two pairs of side limit blocks 12 which are arranged below the conveyor belt 1 and are used to lay the wide edges of the seedling cloth a on the conveyor belt 1.

[0092] In this embodiment, the two pairs of side limit blocks 12 and the single seam plate 11 can be used selectively, and the functions of the two pairs are substantially the same. The two pairs are also installed on the above-mentioned integral frame in an existing common manner. For example, a plurality of cross bars can be directly installed on the vertical plate part of the above-mentioned integral frame for directly connecting the above-mentioned two pairs of side limit blocks 12 or the single seam plate 11.

[0093] A method for using the seedling cloth conveying device comprises the following steps in sequence:

[0094] S1, keep the conveyor belt 1 in a closed state, and first wind the rolled seedling cloth a around the feeding end of the conveyor belt 1 from bottom to top, and then clamp the two side edges between the two guide wheels 2 in a way that the side edges are tilted upward;

[0095] S2, introducing the seedling rope b on the upper surface of the seedling cloth a until the end of the seedling rope b passes under the guide wheel 2 and is exposed 8-10cm from the end of the seedling cloth a, which serves as the binding end of the breeding rope;

[0096] S3, turning on the lifting sewing machine 6, and using it to form a head end stitch d on the seedling cloth a;

[0097] S4, turning on the fixed sewing machine 5, the conveyor belt 1 and the feeding tube c, and using them to form side stitches e on the seedling cloth a, and placing the mussel seedlings between the two raised sides of the seedling cloth a;

[0098] S5. When the lateral distance between the rear end of the seedling rope b and the feed tube c is 5-6 cm, the feed tube c is turned off. When the lateral distance between the rear end of the seedling rope b and the feed tube c is 3-4 cm, the conveyor belt 1 is first turned off, and then the lifting sewing machine 6 is turned on to form the tail end stitch f on the seedling cloth a.

[0099] S6, restarting the conveyor belt 1, and when the side stitching line e passes over the tail stitching line f, shutting down the fixed sewing machine 5;

[0100] S7. When the tail end of the seedling rope b crosses the lifting and cutting machine 7 laterally, the conveyor belt 1 is first shut down, and then the lifting and cutting machine 7 is turned on to cut the seedling cloth a, so that a single breeding rope is completely manufactured.

[0101] In S4, for all mussel seedlings lowering positions on the seedling cloth a, the material is first unloaded and then sewn, because the position of the unloading pipe c is upstream of the seedling cloth conveying direction compared to the fixed sewing machine 5.

[0102] In S5, the above-mentioned lateral distance refers to the distance when the rear end of the seedling rope b has not yet passed over the feeding pipe c.

[0103] In S6, both ends of the side seam e respectively cross the head seam d and the tail seam f, ensuring that the seedling cloth a can fully cover the mussel seedlings.

[0104] In S7, the end stitch d and the end stitch f of the finally obtained breeding rope do not need to be very close to the end side of the seedling cloth a, and then there will be two small hanging areas at both ends of the seedling cloth a, which does not affect the normal use of the breeding rope at all. For details, please refer to the attached Figure 7 .

[0105] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
