Description

Technical Field

[0001] This invention relates to the field of seafood processing equipment technology, specifically to a squid head removal device. Background Technology

[0002] Chinese squid, commonly known as cuttlefish, is an important seafood product in my country with a huge annual output. However, its processing is complex, often requiring the separation of different parts, including the head, viscera, and carcass, for specific processing. Existing squid separation equipment mostly relies on manual operation, which is labor-intensive and time-consuming. A search revealed Chinese patent CN115119867A, which discloses squid processing equipment, including a squid gripping device, a claw-opening mechanism, a main support mechanism, a gripping mechanism, a viscera separation device, a squid head cutting device, and a squid fin removal device. The squid gripping device is used to hold the squid to be processed, and the gripping device is located within the claw-opening mechanism. Above the mechanism, the claw mechanism includes a clamp, a first support rod, a second support rod, and a drive shaft. The first and second support rods are arranged parallel to each other. The drive shaft is used to drive the clamp to move closer to or apart from the first and second support rods. The first and second support rods are connected to the main support mechanism. When the clamp separates from the first and second support rods, it opens the inner wall of the squid's body. The clamping mechanism is located between the first and second support plates. The clamping mechanism includes a first clamping plate and a second clamping plate, both of which are connected to the main support mechanism. The first and second clamping plates are used to clamp the squid's head or place the squid's head... The main support mechanism is used to drive the claw mechanism and the clamping mechanism to move vertically up and down. The viscera separation device is located on one side of the main support mechanism and is used to cut the squid viscera when the clamping forceps and the first and second support rods open the inner wall of the squid carcass. The squid head cutting device is located on the other side of the main support mechanism and is used to cut the squid head when the first and second clamping plates hold the squid head. The squid fin removal device is used to remove the two fins of the squid to be processed. The squid head cutting device is a pneumatic shear connected to the base plate. The aforementioned patent has a substantial deficiency: because there is an overlap between the squid head and the squid carcass without a clear dividing line, the patent's method of directly cutting the squid head and carcass with air shears results in some squid head being cut onto the carcass and some squid carcass being cut onto the head. This leads to incomplete squid heads and carcasses, affecting both appearance and sales. The excess squid carcass portion on the head and the excess squid head portion on the carcass not only wastes squid meat but also requires secondary manual processing to remove the excess squid carcass portion from the head and the excess squid head portion from the carcass, increasing labor intensity.This increased the cost of removing the heads from squid. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a squid head removal device with an ingenious structure, which separates the squid head from the squid body, keeps the squid head structure intact, has high head removal efficiency, and low head removal cost.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

The guide groove 76 is slidably connected to the guide wheel 74 to facilitate the forward and backward movement of the squid carcass support by the guide wheel and the guide frame.

[0021] As attached Figure 1 -Appendix Figure 7A squid carrier 72 is fixedly mounted on the front side of the de-heading frame 50, and a squid de-heading device is provided on the rear side. To further improve the efficiency of squid de-heading, in this embodiment, two squid carriers 72 are arranged side by side on the front side of the de-heading frame 50. Correspondingly, two squid carcass supports 56 and two squid head clamping spaces are provided, which facilitates the simultaneous removal of squid heads from two squid at the same time, resulting in high work efficiency. The squid carriers 72, squid carcass supports 56, and squid head clamping spaces correspond one-to-one, and their quantities can be set as needed. The structure of the squid carrier 72 can be referenced from the applicant's patent application dated July 27, 2022, with patent number CN217609291U, entitled "Clamping, Limiting and Fixing Mechanism and Limiting and Fixing Mechanism in Processing Device". The squid carrier 72 includes a support frame. The support frame is equipped with a clamp, and the rear end of the support frame has a positioning groove. The clamp is connected to the support frame for movement limitation. For details, please refer to the aforementioned patent, which will not be repeated here. The head removal frame 50 of this invention can be equipped with a control system, such as a PLC control system. The squid carcass drive cylinder 54, head removal drive cylinder 59, and head removal clamp drive cylinder 61 are all connected to the control system and driven by the control system. In this invention, the head removal frame 50 is fixed with a slide rail. The two ends of the head removal guide rod 66 are fixedly connected to the head removal frame 50 via connecting seats. The head removal guide seat 65 is sleeved on the head removal guide rod 66 and is slidably connected to the head removal guide rod 66. The head removal guide seat 65 is fixedly connected to the head moving frame 58. The slide rail guides the squid carcass moving frame 53 to move back and forth. The invention also includes a squid head clamping mechanism 67, which guides the squid head removal moving frame 58 to move back and forth via the seat 65 and the head removal guide rod 66. When the first head removal clamping plate 60 and the second head removal clamping plate 62 approach to clamp the squid head, a head removal clamping spring 71 is located between the first head removal clamping plate 60 and the head removal limiting plate 68. The spring force of the head removal clamping spring 71 provides a clamping force to the first head removal clamping plate 60, enabling the first head removal clamping plate 60 and the second head removal clamping plate 62 to clamp the squid head effectively. At the same time, the head removal clamping spring 71 has a buffering effect, allowing the size of the squid clamping space formed by the second head removal clamping plate 62 and the first head removal clamping plate 60 to be adjusted according to the size of the squid head, thereby effectively clamping squid of different sizes. The head removal clamping spring 71, through the head removal... The clamping guide rod 69 guides the head removal process. The rear end of the head removal clamping guide rod 69 is fixed to the head removal limiting block 70. The outer diameter of the head removal limiting block 70 is larger than the inner diameter of the through hole on the head removal limiting plate 68. The head removal limiting block 70 is fixedly connected to the head removal clamping guide rod 69, thus limiting the head removal clamping guide rod 69 and preventing it from separating from the head removal limiting plate 68. In the initial state, the squid carcass drive cylinder 54 is in a retracted state, driving the squid carcass moving frame 53 to move the squid carcass support frame away from the squid carrier 72. The support gear 57 is separated from the support rack plate 55 and does not contact it. The squid carcass support frame is in a horizontal state, and its height is slightly higher than the squid carrier 72 for easy insertion into the squid carcass. The head removal drive cylinder 59 is in an extended state.The second de-heading clamp 62 is located below the positioning groove at the rear end of the squid carrier 72, ensuring that the squid head hangs naturally and is positioned behind the second de-heading clamp 62. The lower end of the squid carrier 72 can be fixedly connected to the de-heading frame 50 via a bracket. The squid de-heading operation steps are as follows:

[0022] Step 1: Place the squid on the support frame of the squid carrier 72 with the squid tail facing forward and the squid head facing the squid head removal device. The squid head hangs down naturally through the positioning groove at the rear end of the support frame, and the front side of the hanging squid head abuts against the rear side of the second head removal clamp 62.

[0023] Step 2: Activate the head removal clamping cylinder 61. The telescopic rod of the head removal clamping cylinder 61 extends, driving the squid head clamping mechanism 67 to move forward. The head removal first clamping plate 60 moves to the rear of the drooping squid head. Under the action of the head removal clamping spring 71, the head removal second clamping plate 62 and the head removal first clamping plate 60 tightly clamp the squid head. Then, close the head removal clamping cylinder 61.

[0024] Step 3: Activate the squid carcass drive cylinder 54. The telescopic rod of the squid carcass drive cylinder 54 extends, driving the squid carcass moving frame 53 to move horizontally forward along with the squid carcass support 56. The front end of the squid carcass support 56 horizontally enters the squid carcass from between the squid head and the squid carcass. As the squid carcass moving frame 53 continues to move forward, the support gear 57 on the squid carcass moving frame 53 reaches the position of the support rack plate 55, supporting... The support gear 57 meshes with the rack of the support rack plate 55. The support gear 57 moves forward along the support rack plate 55 and rotates counterclockwise. The support gear 57 drives the squid carcass support 56 to rotate upward and backward from a horizontal state. The squid carcass support 56, carrying the squid carcass, detaches from the squid carrier 72 and rotates upward and backward until the squid carcass support 56 drives the squid carcass to a vertical state, and then the squid carcass drive cylinder 54 is closed.

[0025] Step 4: Activate the head removal drive cylinder 59. The telescopic rod of the head removal drive cylinder 59 retracts, driving the head removal moving frame 58, the first head removal clamping plate 60, the second head removal clamping plate 62, and the squid head in the squid head clamping space to move backward, away from the squid carcass support 56 and the squid carcass, tearing the squid head off the squid carcass. Then, close the head removal drive cylinder 59.

[0026] Step 5: Activate the head removal clamping cylinder 61. The telescopic rod of the head removal clamping cylinder 61 retracts, driving the squid head clamping mechanism 67 to move backward. The head removal first clamping plate 60 moves backward, away from the squid head, releasing the clamp on the squid head, and the squid head falls off.

[0027] Step 6: Activate the squid carcass drive cylinder 54. The telescopic rod of the squid carcass drive cylinder 54 retracts, the squid carcass moving frame 53 moves backward, the support gear 57 meshes with the rack of the support rack plate 55, the support gear 57 moves backward along the support rack plate 55, the support gear 57 drives the squid carcass support 56 to rotate downward and forward from the vertical position, the squid carcass support 56 rotates with the squid carcass towards the squid carrier 72, as the squid carcass moving frame 53 moves backward, the support gear 57 separates from the support rack plate 55, at this time, the squid carcass support 56 returns to the horizontal position, the squid carcass is placed on the squid carrier 72, the squid carcass moving frame 53 continues to move backward, the squid carcass support 56 is withdrawn from the inside of the squid carcass, the squid carcass support 56 returns to its original position;

[0028] Step 7: Repeat steps 1 through 6 until all squid have been headed, as shown in the attached document. Figure 1 and attached Figure 7 The squid carcass support 56 is vertical and inverted V-shaped, with an arc-shaped upper end and two ends that open downwards in a trumpet shape. This shape of the squid carcass support 56 matches the internal structure of the squid carcass, making it easy to support the squid carcass without tearing the squid's inner wall. After the squid carcass support 56 supports the squid carcass in a vertical position, the first head-removing clamp 60 and the second head-removing clamp 62 clamp the squid head and move it backwards, tearing the squid head off the squid carcass, just like tearing off a squid head by hand. The squid head structure is intact, and the squid carcass structure is also intact, resulting in high head removal efficiency and indirectly reducing the cost of squid head removal.

[0029] The present invention, due to the above-mentioned structure, has the advantages of ingenious structure, separation of squid head and squid body, integrity of squid head structure, high head removal efficiency, and low head removal cost.
