Description

TECHNICAL FIELD

[0001] The utility model relates to an automatic weighing and bagging device for oysters belongs to aquatic product processing technical field. BACKGROUND

[0002] Oysters are important aquatic products, and the quantitative weighing and bagging in the processing link are the key steps affecting production efficiency and product quality. Under the traditional operation mode, this process highly depends on manual operation: workers need to sort oysters from the raw material pile, manually carry them to the weighing device, and then put them into the packaging bag one by one after the weight meets the standard. This mode has significant defects: first, manual carrying and weighing are inefficient, especially in large-scale production, which is difficult to match the high throughput demand, leading to production line bottlenecks; second, long-term repetitive labor can easily cause worker fatigue, increase the operation failure rate, and make it difficult to guarantee the weighing accuracy, which can easily cause single-bag weight deviation, affecting product standardization and customer satisfaction; third, oyster shells are hard but the internal meat is fragile, and frequent throwing or collision during manual operation can easily cause shell breakage or meat damage, resulting in reduced commodity value; fourth, as labor costs are rising year by year, the traditional mode that relies on intensive labor significantly increases the operating costs of enterprises.

[0003] In recent years, the aquatic product processing industry has gradually shifted towards automation, and some automated equipment has been applied in the sorting and packaging of fish, shrimp and other products. However, the automatic weighing and bagging technology for oysters still faces many challenges. First, the morphological differences between individual oysters (such as size, weight, and uneven shell) can easily cause oysters to stack or jam in conventional conveying equipment (such as belt conveyors), affecting continuous operation; second, although existing spiral conveyors can achieve directional conveying, their metal blades and high-speed rotation characteristics can easily cause rigid collisions with oysters, resulting in shell damage or internal tissue damage, making it difficult to meet high-quality processing requirements. In addition, existing weighing control systems are mostly based on batch measurement, lacking precise regulation of dynamic input of individual materials. When the coordination between conveying speed and weighing feedback is insufficient, overfeeding or measurement lag problems can easily occur, leading to bagging weight errors exceeding the allowed range.

[0004] Chinese Patent No. CN210022915U proposes a shell sorting device, the driving unit of which can drive the rotating shaft to rotate, thereby driving the sorting comb to rotate in the sorting pool. The sorting comb can sort out the shell with a size larger than the gap between the comb teeth from the shells in the sorting pool. This technical solution solves the problem of shell sorting, but it cannot realize the integration of continuous weighing and bagging, and it does not effectively solve the problems of shell breakage or meat damage during oyster conveying.

[0005] Meanwhile, the market's requirements for oyster processing efficiency and quality continue to upgrade. On the one hand, the rapid development of fresh food e-commerce and cold chain logistics has driven the demand for oyster pre-packaging to surge; on the other hand, consumers have paid more attention to the integrity of product appearance and weight consistency. Under this background, developing an automated bagging device with efficient conveying, accurate weighing and flexible protection has become a technical problem that the industry urgently needs to break through. Practical new type content

[0006] To solve the defects existing in the prior art, the purpose of the present application is to provide an automatic weighing and bagging device for oysters, which replaces manual work, improves efficiency, reduces work intensity and labor cost.

[0007] The technical scheme of the present application is: an automatic weighing and bagging device for oysters, comprising a feeding pipe obliquely arranged on a frame body, a hopper located at the low end of the feeding pipe and communicating with the feeding pipe, a servo motor provided at the high end of the feeding pipe for driving the rotation of a rotating shaft, the rotating shaft being provided through the feeding pipe and being rotatably connected with the feeding pipe, a spiral conveying blade being provided in the feeding pipe and being connected to the outer periphery of the rotating shaft, a discharge port being provided at the top of the feeding pipe, a receiving hopper being provided below the discharge port and being mounted on the frame body, a weighing sensor being provided between the receiving hopper and the frame body, the weighing sensor being connected to a controller, a sliding baffle being provided at the outlet of the bottom of the receiving hopper, the sliding baffle being connected to a cylinder, the cylinder being connected to the controller, and the controller controlling the cylinder and the servo motor.

[0008] The servo motor is connected to a speed reducer, and the speed reducer is connected to the rotating shaft through a shaft coupling.

[0009] Both ends of the rotating shaft are rotatably connected to both ends of the feeding pipe through bearings, and bearing seats are provided at both ends of the feeding pipe, and the bearings are located on the bearing seats.

[0010] The sliding baffle is obliquely arranged at the bottom of the receiving hopper, and the cylinder is obliquely fixed on the frame body through a cylinder seat.

[0011] The spiral conveying blade and the rotating shaft are coated with a polyurethane coating.

[0012] The beneficial effects of the present application are:

[0013] (1) The present application realizes the automatic conveying and weighing of oysters from the hopper to the receiving hopper through the cooperative work of the spiral conveying blade, the servo motor and the PLC control system. The overall production efficiency is significantly improved by replacing the traditional manual handling, weighing and bagging process.

[0014] (2) The utility model discloses a polyurethane coating is sprayed on spiral conveying blade and all metal surfaces contacted with oyster, and the material has abrasion resistance, impact resistance and corrosion resistance, greatly reduces the direct friction and collision of oyster and metal parts, avoids shell damage or flesh damage, and ensures the appearance and quality of product.

DETAILED DESCRIPTION

[0019] The utility model discloses an automatic weighing and bagging device for oyster, which comprises a feeding pipe 2 obliquely arranged on a frame body 1, a stock bin 3 located at the low end of the feeding pipe 2, a servo motor 4 arranged at the high end of the feeding pipe 2 and used to drive the rotation of a rotating shaft 5. Figure 1 The utility model is further described as follows:

[0020] The utility model discloses an automatic weighing and bagging device for oyster, which comprises a feeding pipe 2 obliquely arranged on a frame body 1, a stock bin 3 located at the low end of the feeding pipe 2, a servo motor 4 arranged at the high end of the feeding pipe 2 and used to drive the rotation of a rotating shaft 5.

[0021] Oysters are loaded into the hopper 3, the bottom of the hopper 3 is communicated with the feeding pipe 2, under the action of gravity, the oysters in the hopper 3 will automatically enter the feeding pipe 2, the servo motor 4 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the spiral conveying blade 6 to rotate, the spiral conveying blade 6 will obliquely upwardly convey the oysters entering the feeding pipe 2, the oysters are moved to the discharge port 7 and automatically fall into the receiving hopper 8 below, the weighing sensor 9 monitors the weight of the oysters in the receiving hopper 8 in real time, after reaching the preset value, a signal is sent to the controller, after the controller receives the signal, an instruction is issued, the servo motor 4 is temporarily stopped, the air cylinder 11 is started, the air cylinder 11 drives the sliding baffle 10 to move, so that the outlet at the bottom of the receiving hopper 8 is opened, a bag containing oysters is placed below the outlet in advance, the bag opening can be manually expanded and directly face the outlet at the bottom of the receiving hopper 8, the weighed oysters directly fall into the bag, and manual bag sealing and removal can be achieved. After the weight of the empty material is reached, the controller issues an instruction again, the air cylinder 11 drives the sliding baffle 10 to close the outlet, the servo motor 4 continues to operate, and the oysters continue to be conveyed into the receiving hopper 8, and the next working cycle is entered.

[0022] The weighing device adopts a spiral conveying mechanism to convey the oysters from the bottom of the hopper 3 layer by layer upwardly. When the weight of the oysters in the receiving hopper 8 approaches the preset value, the PLC will monitor and accurately control the rotating speed of the servo motor 4 in real time. The PLC adjusts the rotating speed of the servo motor 4 to gradually reduce the spiral conveying speed, so as to slow down the conveying speed of the oysters. This speed control can significantly reduce the number of oysters falling into the receiving hopper 8, and even can accurately control the falling number to the level of a single oyster. Through the above control mode, the weighing device can significantly improve the weight accuracy of the oysters in the receiving hopper 8.

[0023] After debugging, the weighing device can accurately control the number of oysters falling into the receiving hopper 8 on the basis of the predetermined weight, allowing the weight of one oyster or the weight of one less oyster. This control strategy takes into account the actual operation, because the size and weight of oysters are not uniform, the preset weight is often difficult to be divided by the number of oysters. After the oysters fall into the receiving hopper 8, the device will monitor the total weight of the receiving hopper 8 in real time and feed this data back to the PLC system. The PLC system then dynamically adjusts and defines the final weight of this bagging according to the final output weight of the receiving hopper 8. This flexible feedback mechanism ensures that the weight of oysters in each bagging can accurately meet the predetermined requirements, neither too much nor too little to affect the customer experience.

[0024] In order to effectively prevent the oysters from being damaged due to collision with metal during conveying, a layer of polyurethane coating is sprayed on all metal surfaces that directly contact the oysters. The polyurethane coating has excellent wear resistance and impact resistance, and can serve as a strong protective barrier to significantly reduce direct friction and collision between oysters and metal, thereby effectively protecting the integrity of the oysters.

[0025] In addition, the polyurethane coating also has good corrosion resistance and adhesion, which can ensure that it will not fall off or be damaged during transportation, providing a durable and reliable protective environment for oysters. Through this optimization, we can not only significantly improve the safety of oyster transportation, but also ensure that oysters still maintain the best quality when they reach the consumers.

[0026] The above is only the preferred embodiment of the present application, it should be pointed out that, for those skilled in the technical field, without departing from the technical principles of the present application, a number of improvements and modifications can be made, these improvements and modifications should also be considered as the protection scope of the present application.
