Description

Technical Field

[0001] This utility model relates to the technical field of aquatic product spiking equipment, and in particular to an automatic spiking device for oysters. Background Technology

[0002] In coastal areas, oyster farmers rely heavily on oyster farming, production, processing, and sales as their economic pillar. Oysters are not only a popular seafood product for human consumption, but also used in high-end catering, as a raw material for health and beauty products, and possess certain medicinal value. When oysters mature, they need to be labeled to facilitate subsequent transportation, sales, and quality traceability. Traditionally, this process requires multiple people working together: oysters are removed from the farming area, others clean impurities from the shells, then labels are applied, they are conveyed to a heat-sealed box using a resistance wire, and finally, the labeled oysters are packed. However, this method not only consumes a large amount of human resources but also results in low production efficiency and high costs. In view of the above problems, the inventors of this case conducted in-depth research on this issue, leading to this invention. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an automatic labeling device for oysters, which solves the problems of high labor cost and low efficiency in the existing oyster labeling process.

[0004] To achieve the above objectives, this utility model adopts the following design scheme: an automatic oyster labeling device, including a frame and an uncoiling machine system. The frame is equipped with motor a, motor b, bearing seats, a robotic arm base, and a resistance wire plate. In the automatic oyster labeling device, motor a is fixed to the frame with bolts and nuts. Motor shaft a is connected to rotating shaft a via coupling a, and rotating shaft a is then connected to a sprocket. The sprocket meshes with a chain, and the movement of the chain realizes the conveying function of the oysters. Motor b is also fixed to the frame with bolts and nuts, and a rotating disk is mounted on its rotating shaft. The friction between the rotating disk and the label causes the label to fall. The base of the robotic arm is fixed to the frame with bolts and nuts, and motor c is mounted on the forearm of the robotic arm. Motor shaft c is connected to the central shaft of the uncoiling machine. The rotation of motor shaft c realizes the extension and retraction of the uncoiling machine shell, completing the label unfolding process. Two resistance wire plates are installed on the automatic oyster spiking equipment to heat-seal the spiked oysters, thus completing the entire oyster spiking process.

[0005] As a further optimization of the above technical solution, the chain link is provided with a through hole, and the bottom of the oyster shell is provided with a connecting post. By inserting the connecting post at the bottom of the oyster shell into the through hole on the chain link, the oyster shell and the chain link are fixedly connected. The oyster shells are installed on the chain links in a spaced-out manner.

[0006] As a further optimization of the above technical solution, the oyster's retaining shell is equipped with two elliptical rubber bands inside, with the major axes of these two rubber bands perpendicular to each other. This ensures that the oyster is placed vertically within the retaining shell, effectively preventing tilting.

[0007] As a further description of the above technical solution: the bottom of the motor shaft c is provided with a gripper, which holds the central shaft of the uncoiler and transmits the power of the motor c to the central shaft.

[0008] As a further description of the above technical solution: the central shaft of the uncoiler is connected to the inner holes of the collar a and collar b by a threaded fit. The actuator converts the rotational motion into linear displacement through the relative movement of the threaded pair, thereby realizing the radial extension of the uncoiler housing and thus realizing the unfolding of the trademark.

[0009] As a further description of the above technical solution: the uncoiler is equipped with a blocking ring, which is located directly below the trademark to prevent the rotating disc from carrying down multiple trademarks at once.

[0010] This utility model has the following beneficial effects: 1. Compared with the prior art, this oyster labeling device is equipped with an uncoiling system, which converts rotational motion into linear displacement through the relative motion of the threaded pair, thereby realizing the unfolding process of the label.

[0011] 2. Compared with the prior art, this oyster labeling device is equipped with an oyster fixing shell, which can keep the oyster upright, making it easy for the label to fall accurately, saving manpower and improving the practicality and convenience of the device.

[0012] 3. Compared with the prior art, this oyster labeling device is equipped with a rotating disk. A semi-cylinder with an arc length of 0.15 mm and a length the same as the width of the rotating disk is provided on the outer cylindrical surface of the rotating disk. The process of labeling the oyster is completed by the friction between the semi-cylinder and the outer surface of the label when the rotating disk rotates.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 6 As shown, this utility model discloses an automatic labeling device for oysters. The oyster labeling device mainly includes a frame 4, an uncoiling machine system, a robotic arm system, a hinged conveyor belt, a rotary table 21, and an infrared sensor 31.

[0019] A motor a5 is mounted on the left side of the frame 4 and is secured to the frame 4 by bolts and nuts. When the motor a5 runs, its power is first transmitted to the motor shaft a25, which then further transmits the power to the sprocket. The sprocket meshes with the chain, thereby driving the chain to move. Oyster shells 1 are mounted on the chain links 26. As the chain moves, these oyster shells 1 also move, ultimately fulfilling the function of conveying oysters from the oyster shells 1.

[0020] A motor b6 is installed on the left side of the frame 4. The motor shaft b28 is connected to the rotating shaft b27 via a coupling b29. A rotating disk 21 is installed on the rotating shaft b27. A semi-cylinder with an arc length of 0.15 mm is provided on the outer cylindrical surface of the rotating disk 21. The rotation of the motor b6 transmits power to the rotating disk 21. The friction between the semi-cylinder and the outer surface of the trademark 12 when the rotating disk 21 rotates completes the process of applying the trademark 12 to the oyster.

[0021] A key 33 is provided between the rotating disk 21 and the rotating shaft b 27 to prevent the rotating disk 21 from moving axially. A bearing seat 22 is provided on the side of the rotating shaft b 27 away from the motor shaft b 28 to provide support.

[0022] A robotic arm base 7 is located on the left side of the frame 4, and is fixed to the frame 4 by bolts and nuts. The robotic arm base 7 is connected to the robotic arm's upper arm 9 via a rotary joint 8, and the robotic arm's upper arm 9 is connected to the robotic arm's lower arm 17 using the same connection method. The robotic arm base 7 mainly provides support for the robotic arm's upper arm 9 and lower arm 17.

[0023] A motor c 19 is installed on the forearm 17 of the robotic arm. A gripper 20 is provided at the bottom of the motor shaft c 18. The gripper 20 holds the central shaft 15 of the uncoiler. The rotation of the motor c 19 transmits power to the central shaft 15, and then the uncoiler housing 13 is extended and retracted through the actuator of the uncoiler.

[0024] An uncoiler system is mounted on the frame 4 and secured to it with bolts and nuts. The uncoiler system is vertically positioned, and the outer surface of the central shaft 15 is threadedly connected to the inner holes of collars a 16 and b 14. The actuator utilizes the relative motion of the threaded pair to convert rotational motion into linear displacement, thereby pushing the uncoiler housing 13 to extend radially, ultimately unfolding the trademark.

[0025] The uncoiler is equipped with a blocking ring 10 located directly below the trademark 12. The diameter of the blocking ring 10 is slightly smaller than that of the trademark 12 and it has a certain thickness. Since the trademark is not fully unrolled and is in close contact with the trademark 12, the blocking ring 10 can prevent the rotating disk 21 from pulling down multiple trademarks at once. The uncoiler is also equipped with a fastening ring 11. The diameter of the fastening ring 11 is slightly larger than that of the trademark 12 and it is located at the mid-section of the trademark 12 to prevent the trademark 12 from shifting.

[0026] The frame 4 has resistance wire plates 3 on both sides to heat-seal the oysters after they have been tagged, thus completing the entire process of oyster tagged.

[0027] An infrared sensor 31 is installed on the left side of the frame 4, and a reflective cylinder 30 is provided on the outer side of the oyster-fixing shell 1. When the oyster-fixing shell 1 moves directly under the uncoiler, the infrared sensor 31 illuminates the reflective cylinder 30 and transmits a signal to motor a 5, causing motor a 5 to stop rotating. At the same time, motor b 6 starts rotating and drives the rotating disk 21. Through the friction between the rotating disk 21 and the trademark 12, the trademark 12 is applied to the oyster. Then motor b 6 stops rotating. At this time, motor c 19 controls the uncoiler shell 13 to expand outward, so that the trademark that is not fully unfolded reaches a fully unfolded state. Afterward, motor a 5 restarts, moving the next oyster forward to directly under the uncoiler, and repeating the above process.

[0028] The oyster labeling device only requires manual cleaning of impurities on the surface of the oyster shells. The oysters are then placed in the oyster fixing shell 1, and subsequent operations are completed automatically by the device. This process greatly reduces manual labor and significantly improves the efficiency of oyster labeling.
