Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fish skin removal devices, specifically, to an automatic skin removal device for salmon. Background Technology
[0002] Salmon should be skinned before consumption. There are three main reasons for this: First, the skin may contain residual scales or have a fishy smell, affecting the taste; second, the skin is prone to shrinking and deforming during cooking, affecting the appearance of the dish; and third, some cooking methods (such as sashimi) emphasize the delicate texture of the fish, and the eating experience is better after removing the skin.
[0003] A fish skinning machine is an automated device specifically designed to remove the skin from fish. It uses mechanical blades or rollers to quickly peel off the skin while preserving the integrity of the fish meat. Widely used in seafood processing plants and restaurant kitchens, it significantly improves processing efficiency and reduces labor costs. Depending on the model, it can process various types of fish, including salmon and cod.
[0004] When the fish skin removal device is in operation, water needs to be added for lubrication to improve the smoothness of the fish's movement. Most existing devices use a single water pipe to add water, which results in poor water uniformity. If the fish's surface area is large, it cannot be fully lubricated, leading to poor smoothness of the fish's movement. In this case, the fish must be pushed manually, making it inconvenient to use. Utility Model Content

Detailed Implementation
[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic salmon peeling device, comprising: The main body 1 of the fish skin removal device has a cutter roller 12 installed in its inner cavity and a motor 11 fixedly installed on its outer wall. The motor 11 is used to drive the cutter roller 12 to rotate. Water circulation mechanism 2 is installed on the main body 1 of the fish skin removal device. Water circulation mechanism 2 is used to uniformly transport lubricating water. The convenient moving mechanism 3 is located on the side of the main body 1 of the fish skin removal device. The convenient moving mechanism 3 is used to improve the flexibility of use of the main body 1 of the fish skin removal device. The water circulation mechanism 2 includes a feeding ramp 26, which is fixedly installed on the top of the fish skin removal device body 1. A support frame 27 is fixedly installed on the bottom of the feeding ramp 26 and on the side of the fish skin removal device body 1. An end baffle 28 is fixedly installed on the inner wall of the feeding ramp 26 near the end. A water distribution baffle 29 is fixedly installed on the inner wall of the feeding ramp 26. A water passage hole 291 is opened at the bottom of the water distribution baffle 29, and an overflow groove 292 is opened at the top of the water distribution baffle 29. An opening is provided on the front of the feeding ramp 26, and the opening is located between the end baffle 28 and the water distribution baffle. Between the end baffle 28 and the water distribution baffle 29, the lubricating water delivered to the inner cavity of the feeding inclined plate 26 will be located between the end baffle 28 and the water distribution baffle 29. The lubricating water will then flow through the water passage holes 291 arranged in the array below the water distribution baffle 29 and flow evenly on the inner wall of the feeding inclined plate 26. This allows the bottom of the large fish body to be fully lubricated, improving the smoothness of the fish body sliding and reducing the probability of manual intervention, thus facilitating the user's use. If the water between the end baffle 28 and the water distribution baffle 29 is full, it will flow to the right from the overflow trough 292 to avoid water overflow and reduce water waste.
[0017] As one implementation method in this embodiment, such as Figure 2 As shown, the water circulation mechanism 2 also includes a receiving frame 21, which is fixedly installed on the front of the main body 1 of the fish skin removal device. A circular groove 22 is provided at the bottom of the receiving frame 21, and a filter screen 23 is movably inserted into the inner cavity of the circular groove 22. A solution tank 24 is fixedly connected to the bottom of the receiving frame 21. Through the design of the receiving frame 21, the discharged water can be received and filtered through the filter screen 23 to realize the function of water circulation and reduce the waste of water resources. During maintenance, the filter screen 23 can be pulled out from the inner cavity of the circular groove 22 for cleaning. The solution tank 24 is used to temporarily store the filtered water.
[0018] As one implementation method in this embodiment, such as Figure 2 As shown, a pump 25 is fixedly installed on the side of the receiving frame 21. The input pipe of the pump 25 is fixedly connected to the bottom of the solution tank 24, and the output pipe of the pump 25 is fixedly connected to the outer wall of the feeding inclined plate 26. By controlling the operation of the pump 25, water inside the solution tank 24 can be extracted and then transported to the feeding inclined plate 26 to realize the function of water supply.
[0019] As one implementation method in this embodiment, such as Figure 2 As shown, a strip mesh 13 is fixedly installed on the inner wall of the main body 1 of the fish skin removal device near the top. A fish skin discharge groove 14 is provided on the main body 1 of the fish skin removal device. Through the design of the strip mesh 13, water at the top of the main body 1 of the fish skin removal device can enter the inner cavity of the main body 1 of the fish skin removal device, reducing the waste of water resources. The peeled fish skin will be discharged from the fish skin discharge groove 14.
[0020] As one implementation method in this embodiment, such as Figure 4 As shown, the convenient moving mechanism 3 includes a support frame 31. The number of support frames 31 is set to two. The two support frames 31 are respectively fixedly installed on both sides of the main body 1 of the fish skin removal device. The bottom of the support frame 31 is provided with a through hole 32. Through the design of the support frame 31, the main body 1 of the fish skin removal device can be stably supported. Through the design of the through hole 32, it is convenient for the universal wheel 35 to pass through.
[0021] As one implementation method in this embodiment, such as Figure 4 As shown, an electric telescopic rod 33 is fixedly installed on the top of the support frame 31. The telescopic end of the electric telescopic rod 33 extends into the inner cavity of the support frame 31 and is fixedly connected to a connecting plate 34. A universal wheel 35 is fixedly installed on the bottom of the connecting plate 34, and a sliding rod 36 is fixedly installed on the top of the connecting plate 34. The sliding rod 36 is slidably connected to the inner wall of the support frame 31. If the structure needs to be rotated, the electric telescopic rod 33 is extended, which causes the connecting plate 34 to move down, causing the universal wheel 35 to pass through the through hole 32 and move down to fit against the ground. The structure can then be pushed and moved, improving the flexibility of use. After moving to the designated position, the electric telescopic rod 33 is retracted, and the support frame 31 supports the structure. The sliding rod 36 will slide on the support frame 31 as the connecting plate 34 rises and falls, thereby improving stability.
[0022] Working principle: To move this structure, the electric telescopic rod 33 is extended, causing the casters 35 to pass through the through hole 32 and move down to the ground. The structure can then be pushed and moved to the designated position. Once the position is reached, the electric telescopic rod 33 is retracted, and the structure is supported by the support frame 31. During use, lubricating water is added to the inner cavity of the solution tank 24 beforehand. The pump 25 is then activated to extract water from the solution tank 24 and transport it to the feeding ramp 26. The lubricating water in the cavity is located between the end baffle 28 and the water distribution baffle 29. The lubricating water then flows through the water passage holes 291 arranged in an array below the water distribution baffle 29 and flows evenly on the inner wall of the feeding inclined plate 26. Then, the motor 11 is controlled to work, which can drive the cutter roller 12 to rotate. Then, the salmon with fish skin can be placed on the feeding inclined plate 26. The salmon will slide to the right naturally, and the fish skin will be peeled off by the rotating cutter roller 12. The fish skin will fall into the inner cavity of the fish skin discharge groove 14, thus realizing the function of removing fish skin.
[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
