Abstract
Description
Technical Field
[0001] This invention relates to the field of shrimp shell removal technology, and in particular to a shrimp shell peeling and recycling mechanism for extracting chitin. Background Technology
[0002] Chitin is a natural high-molecular-weight polysaccharide extracted from the shells of crustaceans such as shrimp and crab, and it is widely used in medicine, chemical industry, food, and agriculture. Traditionally, chitin extraction requires manual or simple mechanical separation of whole shrimp to obtain the shells. In existing technologies, factories obtain shrimp shells by rotating two opposing rollers to separate the shells from the shrimp meat. This method results in shells that are easily broken and have poor integrity. Since the molecular weight distribution of chitin from intact shrimp shells (including the head shell, body shell, and telson) is wider, with chitin from the head shell having the highest relative molecular mass (up to 2 million Da), while broken shrimp shells have a narrower molecular weight distribution, intact shrimp shells are required for chitin extraction. Therefore, there is an urgent need for a shrimp shell stripping and recycling mechanism for chitin extraction that can not only separate shrimp meat from the shell but also ensure the integrity of the shell. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a shrimp shell peeling and recycling mechanism for extracting chitin, which can not only separate shrimp meat from shrimp shell, but also ensure the integrity of shrimp shell.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a shrimp shell peeling and recycling mechanism for extracting chitin, comprising: The conveyor belt is connected to the ground along the X direction. Baffles are provided on both sides of the conveyor belt, and a drive motor is provided at one end of the baffle. The drive motor is connected to the conveyor belt for transmission. The limiting device includes a rectangular block with a limiting groove. One end of the limiting groove is equipped with a fastening device for clamping the tail of the shrimp, so that the shrimp's abdomen faces down and its back faces up, with the shrimp body facing the drive motor. The other end of the shrimp is higher than the baffle and located outside the conveyor belt. The fastening device includes a first spring, a second spring, a first clamping plate, and a second clamping plate. The inner wall of the limiting groove away from the drive motor has a vertical groove. One end of the first spring is connected to the upper part of the vertical groove, and the first clamping plate is connected to the other end of the first spring. The axis of the first spring is vertical. One end of the second spring is connected to the bottom of the vertical groove. The second spring is coaxial with the first spring, and the second clamping plate is connected to the other end of the second spring. The second clamping plate is located below the first clamping plate. The gripping device is located on one side of the conveyor belt and on the same side as the drive motor. The gripping device includes a telescopic cylinder, a moving plate, and cylinder grippers. The telescopic cylinder is connected to the ground through a fixed plate. The axis of the telescopic cylinder is Y-direction. The moving plate is connected to the telescopic cylinder, and the cylinder grippers are connected to the moving plate. In a certain state, the other end of the shrimp body from the tail of the limiting device is located between the two gripping arms of the cylinder grippers. The collection box is located directly below the moving board's path.
[0005] Furthermore, a handle is provided above the first clamping plate. The handle is a vertical limiting rod, with one end of the limiting rod extending above the limiting groove.
[0006] Furthermore, the inner walls of the limiting groove gradually widen towards the drive motor on both sides.
[0007] Furthermore, the inner wall of the limiting groove on the side away from the drive motor is provided with strip grooves on both sides. The strip grooves are connected to the limiting groove and the vertical groove. A limiting guide post is provided in the strip groove. The axis of the limiting guide post is vertical. The first clamping plate and the second clamping plate are slidably connected to the limiting guide post.
[0008] Furthermore, there are two cylinder grippers, and the distance between the two cylinder grippers matches the gap between two adjacent limiting devices on the conveyor belt.
[0009] The beneficial effects of this invention are as follows: Compared with the prior art, by setting a limiting device and a clamping device, the shrimp shells can be obtained more completely than the original factory's method of squeezing shrimp with two opposing rotating rollers, thereby increasing the content of chitin in the shrimp shells during subsequent extraction.

[0012] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0013] Please refer to Figures 1 to 4 A shrimp shell peeling and recycling mechanism for extracting chitin, comprising: Conveyor belt 1 is connected to the ground along the X direction. Baffles 11 are provided on both sides of conveyor belt 1. A drive motor 111 is provided at one end of the baffle 11. The drive motor 111 is connected to the conveyor belt 1 in a transmission connection. The limiting device 2 includes a rectangular block 21 with a limiting groove 211. One end of the limiting groove 211 is provided with a fastening device 3, which is used to clamp the tail of the shrimp, so that the shrimp's abdomen is facing down and its back is facing up, with the shrimp body facing the drive motor 111. The other end of the shrimp is higher than the baffle 11 and located outside the conveyor belt 1. The fastening device 3 includes a first spring 31, a second spring 32, a first clamping plate 33, and a second clamping plate 34. The inner wall of the limiting groove 211 away from the drive motor 111 is provided with a vertical groove 2111. One end of the first spring 31 is connected to the upper part of the vertical groove 2111, and the first clamping plate 33 is connected to the other end of the first spring 31. The axis of the first spring 31 is vertical. One end of the second spring 32 is connected to the bottom of the vertical groove. The second spring 32 is coaxial with the first spring 31. The second clamping plate 34 is connected to the other end of the second spring 32 and is located below the first clamping plate 33.
[0014] The clamping device 4 is located on one side of the conveyor belt 1. The clamping device 4 and the drive motor 111 are located on the same side. The clamping device 4 includes a telescopic cylinder 41, a moving plate 42 and a cylinder gripper 43. The telescopic cylinder 41 is connected to the ground through a fixed plate. The axis of the telescopic cylinder 41 is Y. The moving plate 42 is connected to the telescopic cylinder 41. The cylinder gripper 43 is connected to the moving plate 42. In a certain state, the other end of the shrimp body in the limiting device 2, away from the tail, is located between the two gripping arms 431 of the cylinder gripper 43. Collection box 5 is located directly below the moving path of moving plate 42.
[0015] In the above embodiments, the conveyor belt 1 can be set to operate intermittently, so that the shrimp in the limiting device 2 can be accurately positioned between the two clamping arms 431 of the cylinder gripper 43. After the shrimp, whose heads and shrimp veins have been removed, are frozen, they are placed on the limiting device 2. Because the shrimp have been frozen, their bodies protrude from their shells. The tail of the shrimp is fixed to one end of the limiting groove 211 by the first clamping plate 33 and the second clamping plate 34 of the fastening device 3. The shrimp body is in contact with both sides of the inner wall of the limiting groove 211. The shrimp is held upright with the end of its body away from its tail facing the other end of the limiting groove 211, so that the shrimp body is located outside one side of the conveyor belt 1. Then the conveyor belt 1 transports the limiting device 2 to the clamping device 4, so that the shrimp body is positioned upright. The shrimp is positioned between the two gripping arms 431 of the cylinder gripper 43. Then, the forward movement of the telescopic cylinder 41 drives the gripping arms 431 of the cylinder gripper 43 to grip the shrimp body. Then, the telescopic cylinder 41 moves in the reverse direction to pull the shrimp body out of the shrimp shell, thus separating the shrimp shell from the shrimp meat. Then, the cylinder gripper 43 moves to the top of the collection box 5, the cylinder clamps and releases the gripping arms 431, and the shrimp meat falls into the collection box 5. The shrimp shell continues to be conveyed in the X direction by the conveyor belt 1. The shrimp shells are removed and collected by the staff. Compared with the existing technology, by setting the limiting device 2 and the gripping device 4, the shrimp shells can be obtained more completely than the original factory that used two opposing rotating rollers to squeeze the shrimp, thereby increasing the content of chitin in the shrimp shell during subsequent extraction.
[0016] As an optional implementation, a handle 331 is provided above the first clamping plate 33. The handle 331 is a vertical limiting rod, and one end of the limiting rod is higher than the limiting groove 211.
[0017] In the above embodiments, by providing a handle 331, the staff can quickly lift the first clamping plate 33 using the handle 331, thereby placing the tail of the shrimp between the first clamping plate 33 and the second clamping plate 34.
[0018] As an optional implementation, the inner walls of the limiting groove 211 gradually widen towards the drive motor 111.
[0019] In the above embodiments, the limiting groove 211 is configured to gradually widen on both sides of the inner wall facing the drive motor 111, thereby adapting to the characteristic that the shrimp body gradually narrows from the shrimp tail.
[0020] As an optional implementation, the inner wall of the limiting groove 211 away from the drive motor 111 is provided with strip grooves 2112 on both sides. The strip grooves 2112 are connected to the limiting groove 211 and the vertical groove 2111. A limiting guide post 21121 is provided in the strip groove 2112. The axis of the limiting guide post 21121 is vertical. The first clamping plate 33 and the second clamping plate 34 are slidably connected to the limiting guide post 21121.
[0021] In the above embodiments, the stability of the spring can be further enhanced by setting the limiting guide post 21121.
[0022] As an optional implementation, there are two cylinder grippers 43, and the distance between the two cylinder grippers 43 matches the gap between two adjacent limiting devices 2 of the conveyor belt 1.
[0023] In the above embodiments, by setting two cylinder grippers 43, the shrimp bodies of the two limiting devices 2 can be shelled simultaneously, thereby improving the shelling efficiency.
[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
