Description

Technical Field

[0001] This invention belongs to the field of descaling machine technology, specifically relating to an automatic fish descaling device and its usage method. Background Technology

[0002] A descaling machine is a specialized machine used to remove scales from the surface of fish. It is widely used in the seafood processing industry to improve production efficiency and product quality. The working principle of a descaling machine typically includes steps such as feeding the fish, descaling, back-opening (some machines have this function), washing, and discharging. Descaling is achieved by an internal scraping device that contacts the fish and scrapes off the scales. This scraping device is usually made of a hard material, such as stainless steel, to ensure efficient descaling.

[0003] A search revealed a fish scaler disclosed in Chinese patent CN107041415B, belonging to the field of food processing machinery technology. This fish scaler consists of a frame, a screening and discharging device, a feeding device, a weighing device, and a friction scaler. The friction scaler is mounted on the frame, with a weighing device above it and a feeding device positioned above one side of the weighing device, connected to the friction scaler via the weighing device. The screening and discharging device is located below the friction scaler. This fish scaler has a simple structure, high production efficiency, and achieves continuous and mechanized fish scaler production, solving the problems of high labor intensity and low production efficiency associated with existing manual scaler methods. It is particularly suitable for use in pre-processing fish in production enterprises.

[0004] However, the above technical solutions have solved the problems of high labor intensity and low production efficiency in existing manual descaling. However, the existing descaling machine is effective for fish of fixed size. When the fish are large or small, the scales on the surface of the fish may not be scraped off completely or the scale-scraping gear may become embedded in the fish meat, thus affecting the descaling effect. Summary of the Invention

[0010] The descaling mechanism comprises two sets arranged symmetrically. One set includes: a mounting block, a mounting plate, a second motor, two third gears, a fixed rod, a fourth gear, two dividing columns, multiple first gears, multiple first scraping teeth, multiple rotating rods, multiple second gears, and multiple second scraping teeth. The mounting block is fixedly connected to the side end of the slide box, the mounting plate is fixedly connected to the side end of the slide box, the second motor is fixedly connected to the circular groove of the mounting block, the two third gears are respectively fixedly connected to the two output ends of the second motor, the fixed rod is fixedly connected to the lower end of one of the third gears, the fourth gear is fixedly connected to the lower end of the fixed rod, the two dividing columns are fixedly connected to one side end of the slide box, the multiple first gears are rotatably connected to the upper and lower inner walls of the slide box via rotating shafts, the multiple first scraping teeth are respectively fixedly connected to the lower ends of the multiple first gears, the multiple rotating rods are rotatably connected between the two dividing columns, the multiple second gears are respectively fixedly connected to the circumferential surfaces of the multiple rotating rods, and the multiple second scraping teeth are respectively fixedly connected to the circumferential surfaces of the multiple rotating rods.

[0011] As a preferred embodiment of the present invention, two protective shells are fixedly connected to both sides of the descaling machine, and a support machine is fixedly connected to the lower end of the descaling machine.

[0012] As a preferred embodiment of the present invention, a guide cylinder is fixedly connected to one side of the descaling machine box, a discharge pipe is fixedly connected to the other side of the descaling machine box, and a feed scalding pipe is fixedly connected to the lower end of the descaling machine box.

[0014] As a preferred embodiment of the present invention, two fixing blocks are fixedly connected to both sides of the descaling machine, and pull rings are fixedly connected to the upper ends of the four fixing blocks.

[0015] In a preferred embodiment of the present invention, four mounting cylinders are fixedly connected to the side of the descaling machine box, and each of the four mounting cylinders is slidably connected to a water pipe.

[0019] As a preferred embodiment of the present invention

[0020] A method for automatically descaling fish includes:

[0021] S1. When descaling fish of different sizes, the first motor can be used to drive the swing arm to rotate, so that the two connecting rods drive the two sliding boxes to move closer to each other, so that the two sets of descaling mechanisms are in contact with the surface of the fish. Then, the second motor is used to drive multiple first and second scraping teeth to scrape off the scales on the surface of the fish. The fish scales fall to the ground through the feed tube, thereby achieving the effect of removing fish scales. By adjusting the descaling mechanism, the scales can be removed from fish of different sizes.

[0022] S2. When multiple first and second scraping teeth are scraping the scales off the fish, the fish will be discharged through the discharge pipe under the friction of the first and second scraping teeth. As the fish moves inside the descaling machine, the third scraping tooth will scrape off the scales on the surface of the fish, reducing the number of scales on the fish's surface. The sequence of multiple first and second scraping teeth on the rotating shaft allows the multiple first and second scraping teeth to carry the fish out through the discharge pipe.

[0023] S3. The water pipe installed on the surface of the descaling machine can be connected to a water source. After using the descaling machine, the scraping gears inside the machine can be cleaned by holding the water pipe, thereby increasing the cleanliness of the machine. The pull rings installed at both ends of the descaling machine can be used to lift the machine and move it up and down, making it convenient for workers to carry.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. When descaling fish of different sizes, the first motor drives the swing arm to rotate, causing two connecting rods to move two sliding boxes closer together, so that the two sets of descaling mechanisms are in contact with the surface of the fish. Then, the second motor drives multiple first and second scraping teeth to scrape off the scales on the surface of the fish. The scales fall to the ground through the feed pipe, thus achieving the effect of removing fish scales. By adjusting the descaling mechanism, it is possible to remove scales from fish of different sizes. When multiple first and second scraping teeth are scraping the scales from the fish, the fish will be discharged through the discharge pipe under the friction of the first and second scraping teeth. When the fish moves in the descaling machine, the third scraping tooth will scrape off the scales on the surface of the fish, which can reduce the scales on the surface of the fish. The sequence of multiple first and second scraping teeth on the rotating shaft allows multiple first and second scraping teeth to drive the fish through the discharge pipe, thus achieving the effect of removing scales from fish of different sizes.

[0026] 2. The scale feed pipe installed under the scale removal machine allows the scales scraped off by the scale removal mechanism to be discharged through the scale feed pipe. The water pipe installed on the surface of the scale removal machine can remove the scales inside the scale removal machine by connecting to a water source, increasing the cleanliness of the scale removal machine. The protective shells installed on both sides of the scale removal machine can be used to protect the second motor.

[0027] 3. The pull rings installed on both sides of the descaling machine can move the descaling machine through the lifting equipment. The support machine installed under the descaling machine can be used to support the operation of the descaling machine. The guide cylinder installed on the surface of the descaling machine can guide the fish into the descaling machine. The support frame installed on the descaling machine can install the first motor on the descaling machine. Attached Figure Description

[0046] like Figure 1 As shown, two protective shells 4 are fixedly connected to both ends of the descaling machine housing 1, which can be used to protect the second motor 516. A support machine 9 is fixedly connected to the lower end of the descaling machine housing 1, which can be used to support the descaling machine housing 1.

[0047] like Figure 2 As shown, a feed guide cylinder 8 is fixedly connected to the side of the descaling machine 1, which can guide the fish into the descaling machine 1. A discharge pipe 11 is fixedly connected to the other side of the descaling machine 1, which can discharge the descaled fish. A feed scale pipe 12 is fixedly connected to the lower end of the descaling machine 1, which can discharge the fish scales.

[0048] like Figure 3As shown, two fixed brackets 15 are fixedly connected to the upper and lower inner walls of the descaling machine 1, which can be used to install the rotating rods 14. The rotating rods 14 are rotatably connected between the four fixed brackets 15, which can be used to install the third scale-removing teeth 13. Multiple third scale-removing teeth 13 are fixedly connected to the circumferential surface of the four rotating rods 14, which can remove the scales from the upper surface of the fish.

[0049] like Figure 1 As shown, two fixing blocks 3 are fixedly connected to both ends of the descaling machine housing 1, allowing the pull rings 10 to be installed on the descaling machine housing 1. Pull rings 10 are fixedly connected to the upper ends of the four fixing blocks 3, allowing the descaling machine housing 1 to be moved by a lifting device.

[0050] like Figure 1 As shown, four mounting cylinders 6 are fixedly connected to the side of the descaling machine housing 1, which can be used to install water pipes 7. Each of the four mounting cylinders 6 is slidably connected to a water pipe 7. By connecting to a water source, the fish scales inside the descaling machine housing 1 can be removed.

[0051] like Figure 2 , Figure 3 and Figure 4 As shown, multiple first gears 503 mesh with each other and can be used to drive the first scraping teeth 504 to remove fish scales. Multiple second gears 507 mesh with each other and can drive the second scraping teeth 508 to rotate.

The other third gear 517 meshes with one of the second gears 507, which can drive the second scraping tooth 508 to remove scales from the fish surface.

[0054] The working principle and usage of this invention are as follows: When descaling fish of different sizes, the first motor 501 drives the swing rod 515 to rotate, causing the two connecting rods 513 to drive the two sliding boxes 502 to move closer to each other, so that the two sets of descaling mechanisms are in contact with the surface of the fish. Then, the second motor 516 drives multiple first scraping teeth 504 and second scraping teeth 508 to scrape off the scales on the surface of the fish. The scales fall to the ground through the scale feeding pipe 12, thus achieving the effect of removing fish scales. By adjusting the descaling mechanism, it is possible to remove scales from fish of different sizes. When multiple first scraping teeth 504 and second scraping teeth 508 are scraping the scales off the fish, the fish will be discharged through the discharge pipe 11 under the friction of the first scraping teeth 504 and second scraping teeth 508. When the fish moves inside the descaling machine 1, the third scraping tooth 13 will scrape off the scales on the surface of the fish, which can reduce the scales on the surface of the fish. The sequence of multiple first scraping teeth 504 and second scraping teeth 508 on the rotating shaft allows multiple first scraping teeth 504 and second scraping teeth 508 to drive the fish through the discharge pipe 11 and discharge the fish, thereby achieving the effect of scraping scales off fish of different sizes.
