Description

Technical Field

[0001] The present invention relates to the technical field of seafood processing equipment, and specifically refers to a method for bionic decapitation of squids. Background Art

[0002] Chinese squid, commonly known as squid, is an important seafood in my country, with a huge annual output. At the same time, the processing steps are cumbersome. When processing, it is often necessary to divide and separate different parts of the squid, and separate the head, viscera and carcass of the squid from each other so that different parts can be processed as needed. However, most of the existing squid separation equipment can only be operated manually, which has high labor intensity, time-consuming and labor-intensive. After searching, Chinese patent CN115119867A discloses a squid processing device, including a squid clamping device, a claw mechanism, a main body support mechanism, a clamping mechanism, an viscera separation device, a squid head cutting device, and a squid fin removal device. The squid clamping device is used to clamp the squid to be processed, and the squid clamping device is located at the claw The mechanism is above the claw mechanism, which includes a clamp, a first strut, a second strut, and a driving shaft. The first strut and the second strut are arranged parallel to each other. The driving shaft is used to drive the clamp and the first strut and the second strut to approach or separate from each other. The first strut and the second strut are connected to the main support mechanism. When the clamp and the first strut and the second strut are separated from each other, the inner wall of the squid carcass is spread open. The clamping mechanism is arranged between the first support plate and the second support plate. The clamping mechanism includes a first clamp and a second clamp. The first clamp and the second clamp are both connected to the main support mechanism. The first clamp and the second clamp are used to clamp the squid head or place the squid head The main body supporting mechanism is used to drive the claw mechanism and the clamping mechanism to move up and down in the vertical direction. The viscera separation device is arranged on one side of the main body supporting mechanism. The viscera separation device is used to cut off the squid viscera when the clamp and the first support rod and the second support rod open the inner wall of the squid carcass. The squid head cutting device is arranged on the other side of the main body supporting mechanism. The squid head cutting device is arranged on the other side of the main body supporting mechanism. The squid head cutting device is used to cut off the squid head when the first clamp and the second clamp clamp 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 gas shear, and the gas shear is connected to the bottom plate. The gas shear is arranged horizontally, and the gas shear is suitable for moving left and right in the horizontal direction. The substantial deficiency of the above patent is that because there is an overlapping part between the squid head and the squid carcass, and there is no clear dividing line, the above patent uses the gas shear to directly cut the squid head and the squid carcass, which will cut part of the squid head onto the squid carcass, and part of the squid carcass onto the squid head, resulting in an incomplete squid head and an incomplete squid carcass, which not only looks bad, but also affects the sales of both. The excess squid carcass part on the squid head and the excess squid head part on the squid carcass not only cause the waste of squid meat, but also require manual secondary processing to remove the excess squid carcass part on the squid head and the excess squid head part on the squid carcass, which increases the labor intensity.Increases the cost of squid decapitation. Summary of the Invention

[0003] The object of the present invention is to solve the deficiencies of the prior art and provide a bionic squid decapitation method with a clever structure, where the squid head is torn apart from the squid carcass, the squid head has a complete structure, high decapitation efficiency, and low decapitation cost.

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

[0005] A bionic squid decapitation method, characterized by comprising the following steps:

[0006] First step: Place the squid on the support frame of the squid carrier, with the squid tail facing forward and the squid head facing the squid decapitation device. The squid head passes through the rear positioning groove of the support frame backward and hangs down in a natural vertical state, and the front side of the hanging squid head abuts against the rear side of the second decapitation splint.

[0007] Second step: Start the decapitation splint driving cylinder. The telescopic rod of the decapitation splint driving cylinder extends, driving the squid head clamping mechanism to move forward. The first decapitation splint moves to the rear side of the hanging squid head. Under the action of the decapitation clamping spring, the second decapitation splint and the first decapitation splint tightly clamp the squid head, and then close the decapitation splint driving cylinder.

[0008] Third step: Start the squid carcass driving cylinder. The telescopic rod of the squid carcass driving cylinder extends, driving the squid carcass moving frame to move the squid carcass support horizontally forward. The front end of the squid carcass support horizontally enters the squid carcass between the squid head and the squid carcass. As the squid carcass moving frame continues to move forward, the support gear on the squid carcass moving frame reaches the position of the support rack plate. The support gear meshes with the rack of the support rack plate, and the support gear moves forward along the support rack plate. The support gear rotates from front to back, driving the squid carcass support to rotate upward and backward from the horizontal state. The squid carcass support drives the squid carcass to rotate upward and backward away from the squid carrier until the squid carcass support drives the squid carcass to a vertical state, and then close the squid carcass driving cylinder.

[0009] Fourth step: Start the decapitation driving cylinder. The telescopic rod of the decapitation driving cylinder retracts, driving the decapitation moving frame, the first decapitation splint, the second decapitation splint, and the squid head in the squid head clamping space to move backward, away from the squid carcass support and the squid carcass, tearing the squid head off the squid carcass, and then close the decapitation driving cylinder.

[0010] Fifth step: Start the decapitation splint driving cylinder. The telescopic rod of the decapitation splint driving cylinder retracts, driving the squid head clamping mechanism to move backward. The first decapitation splint moves backward, away from the squid head, releasing the clamping of the squid head, and the squid head drops.

[0011] Step 6: Start the squid carcass drive cylinder. The telescopic rod of the squid carcass drive cylinder retracts, and the squid carcass moving frame moves backward. The support gear meshes with the rack of the support rack plate, and the support gear moves backward along the support rack plate. The support gear rotates from the back to the front, driving the squid carcass support to rotate downward and forward from the vertical state. The squid carcass support drives the squid carcass to rotate towards the squid carrier. As the squid carcass moving frame moves backward, the support gear separates from the support rack plate. At this time, the squid carcass support returns to the horizontal state, places the squid carcass on the squid carrier, the squid carcass moving frame continues to move backward, the squid carcass support withdraws from inside the squid carcass, and the squid carcass support returns to its original position;

[0012] Step 7: Repeat Step 1 to Step 6 until all the squids to be decapitated have completed the decapitation operation.

[0013] The squid vehicle of the present invention is fixedly connected to the decapitation frame through a bracket.

The decapitation frame is provided with a squid carcass moving frame, a squid carcass driving cylinder, a decapitation moving frame, and a decapitation driving cylinder. The squid carcass moving frame is slidably connected to the decapitation frame through a slideway. The squid carcass moving frame is driven by the squid carcass driving cylinder. The cylinder block of the squid carcass driving cylinder is fixed on the decapitation frame. A bracket groove is provided at the front end of the decapitation frame to facilitate the upward passing of the squid carcass support through the bracket groove to be in a vertical state. A support rack plate is provided at the front end of the decapitation frame. A squid carcass support is provided at the front end of the squid carcass moving frame. The squid carcass support is in a V shape. The squid carcass support passes through the bracket groove. The two ends of the squid carcass support extend horizontally to the left and right to form connection ends. Support connecting shafts are respectively provided on the left and right sides of the squid carcass support. The connection ends of the squid carcass support are fixedly connected to the support connecting shafts. The support connecting shafts are hinged to the squid carcass moving frame. At least one side of the left and right sides of the squid carcass support is provided with a support gear. The support gear is fixed on the support connecting shaft. The support gear meshes with the rack on the support rack plate to drive the squid carcass support to change from a horizontal state to a vertical state. The support rack plate is fixedly connected to the decapitation frame to support the squid carcass by inserting the squid carcass support into the squid carcass. A first decapitation clamping plate is provided below the squid carcass support. A second decapitation clamping plate is provided in front of the first decapitation clamping plate. The first decapitation clamping plate is driven by the decapitation clamping plate driving cylinder. The first decapitation clamping plate and the second decapitation clamping plate cooperate to form a squid head clamping space. The second decapitation clamping plate is located below the squid vehicle. The second decapitation clamping plate is fixedly connected to the decapitation moving frame through a support plate. The cylinder block of the decapitation clamping plate driving cylinder is fixed on the decapitation moving frame. The decapitation moving frame is slidably connected to the decapitation frame through a decapitation guide seat and a decapitation guide rod. The decapitation moving frame is driven by the decapitation driving cylinder. The cylinder block of the decapitation driving cylinder is fixed on the decapitation frame to clamp the squid head through the squid head clamping space. The decapitation driving cylinder drives the squid head clamping space to move backward with the squid head to tear the squid head off the squid carcass.

[0014] On the first head-removing clamping plate of the present invention, there is a squid head clamping mechanism, which includes a head-removing limit plate, head-removing clamping guide rods, head-removing limit blocks, and head-removing clamping springs. Behind the first head-removing clamping plate, there is a head-removing limit plate. Between the head-removing limit plate and the first head-removing clamping plate, there are head-removing clamping guide rods arranged at intervals. The head-removing limit plate is fixedly connected to the telescopic rod of the head-removing clamping plate driving cylinder. The head-removing limit plate is provided with rod through-holes. The front ends of the head-removing clamping guide rods are fixedly connected to the first head-removing clamping plate, and the rear ends pass through the rod through-holes on the head-removing limit plate and are fixedly connected to the head-removing limit blocks. The head-removing clamping guide rods are movably connected to the head-removing limit plate. The head-removing clamping guide rods are sleeved with head-removing clamping springs. One end of the head-removing clamping spring abuts against the head-removing limit plate, and the other end abuts against the first head-removing clamping plate, so as to support and limit the first head-removing clamping plate through the head-removing clamping spring, enabling the first head-removing clamping plate and the second head-removing clamping plate to clamp squid heads of different sizes well.

Detailed implementation manners

[0024] The following further describes in detail the specific implementation manners of the present invention in conjunction with the accompanying drawings.

[0025] A bionic squid head-removing method, characterized by comprising the following steps:

[0026] First step: 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-removing device. The squid head passes through the rear positioning groove of the support frame and hangs down in a natural vertical state. The front side of the hanging squid head abuts against the rear side of the head-removing second clamping plate 62.

[0027] Second step: Start the head-removing clamping plate driving cylinder 61. The telescopic rod of the head-removing clamping plate driving cylinder 61 extends, driving the squid head clamping mechanism 67 to move forward. The head-removing first clamping plate 60 moves to the rear side of the hanging squid head. Under the action of the head-removing clamping spring 71, the head-removing second clamping plate 62 and the head-removing first clamping plate 60 tightly clamp the squid head, and then turn off the head-removing clamping plate driving cylinder 61.

[0028] Third step: Start the squid carcass driving cylinder 54. The telescopic rod of the squid carcass driving cylinder 54 extends, driving the squid carcass moving frame 53 to horizontally move forward with the squid carcass support 56. The front end of the squid carcass support 56 horizontally enters the squid carcass 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. The support gear 57 meshes with the rack of the support rack plate 55, and the support gear 57 moves forward along the support rack plate 55. The support gear 57 rotates from front to back, driving the squid carcass support 56 to rotate upward and backward from the horizontal state. The squid carcass support 56 drives the squid carcass to rotate upward and backward away from the squid carrier 72 until the squid carcass support 56 drives the squid carcass to a vertical state, and then turn off the squid carcass driving cylinder 54.

[0029] Step 4: Start the head-removing driving cylinder 59. The telescopic rod of the head-removing driving cylinder 59 retracts, driving the head-removing moving frame 58, the first head-removing clamping plate 60, the second head-removing clamping plate 62, and the squid head within the squid head clamping space to move backward, away from the squid carcass support 56 and the squid carcass, tearing the squid head from the squid carcass, and then close the head-removing driving cylinder 59;

[0030] Step 5: Start the head-removing clamping plate driving cylinder 61. The telescopic rod of the head-removing clamping plate driving cylinder 61 retracts, driving the squid head clamping mechanism 67 to move backward, and the first head-removing clamping plate 60 to move backward, away from the squid head, releasing the clamping on the squid head, and the squid head drops off;

[0031] Step 6: Start the squid carcass driving cylinder 54. The telescopic rod of the squid carcass driving cylinder 54 retracts, and 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, rotates from the rear to the front, drives the squid carcass support 56 to rotate downward and forward from the vertical state. The squid carcass support 56 drives the squid carcass to rotate towards the squid carrier 72. As the squid carcass moving frame 53 moves backward, the support gear 57 disengages from the support rack plate 55. At this time, the squid carcass support 56 returns to the horizontal state, places the squid carcass on the squid carrier 72, the squid carcass moving frame 53 continues to move backward, and the squid carcass support 56 withdraws from inside the squid carcass and returns to its original position;

[0032] Step 7: Repeat Steps 1 to 6 until all the squids to be beheaded have completed the beheading operation.

[0033] The squid vehicle 72 of the present invention is fixedly connected to the decapitation frame 50 via a bracket.

The decapitation frame 50 is provided with a squid carcass moving frame 53, a squid carcass driving cylinder 54, a decapitation moving frame 58, and a decapitation driving cylinder 59. The squid carcass moving frame 53 is slidably connected to the decapitation frame 50 via a slideway. The squid carcass moving frame 53 is driven by the squid carcass driving cylinder 54. The cylinder block of the squid carcass driving cylinder 54 is fixed on the decapitation frame 50. A bracket groove 63 is provided at the front end of the decapitation frame 50 to facilitate the squid carcass bracket to pass upward through the bracket groove and be in a vertical state. A support rack plate 55 is provided at the front end of the decapitation frame 50. A squid carcass bracket 56 is provided at the front end of the squid carcass moving frame 53. The squid carcass bracket 56 is in a V shape. The squid carcass bracket 56 passes through the bracket groove 63. The two ends of the squid carcass bracket 56 extend horizontally to the left and right to form connection ends 64. Support connecting shafts are respectively provided on the left and right sides of the squid carcass bracket 56. The connection ends 64 of the squid carcass bracket 56 are fixedly connected to the support connecting shafts. The support connecting shafts are hinged to the squid carcass moving frame 53. At least one side of the left and right sides of the squid carcass bracket 56 is provided with a support gear 57. The support gear 57 is fixed on the support connecting shaft. The support gear 57 meshes with the rack on the support rack plate 55 to drive the squid carcass bracket 56 to change from a horizontal state to a vertical state. The support rack plate 55 is fixedly connected to the decapitation frame 50 to support the squid carcass by extending the squid carcass bracket into the squid carcass. A first decapitation clamping plate 60 is provided below the squid carcass bracket 56. A second decapitation clamping plate 62 is provided in front of the first decapitation clamping plate 60. The first decapitation clamping plate 60 is driven by the decapitation clamping plate driving cylinder 61. The first decapitation clamping plate 60 and the second decapitation clamping plate 62 cooperate to form a squid head clamping space. The second decapitation clamping plate 62 is located below the squid vehicle 72. The second decapitation clamping plate 62 is fixedly connected to the decapitation moving frame 58 via a support plate. The cylinder block of the decapitation clamping plate driving cylinder 61 is fixed on the decapitation moving frame 58. The decapitation moving frame 58 is slidably connected to the decapitation frame 50 via a decapitation guide seat 65 and a decapitation guide rod 66. The decapitation moving frame 58 is driven by the decapitation driving cylinder 59. The cylinder block of the decapitation driving cylinder 59 is fixed on the decapitation frame 50 to clamp the squid head through the squid head clamping space. The decapitation driving cylinder drives the squid head clamping space to move the squid head backward to tear the squid head off the squid carcass.

[0034] The decapitation first splint 60 of the present invention is provided with a squid head clamping mechanism 67. The squid head clamping mechanism 67 includes a decapitation limit plate 68, a decapitation clamping guide rod 69, a decapitation limit block 70, and a decapitation clamping spring 71. A decapitation limit plate 68 is provided behind the decapitation first splint 60. A decapitation clamping guide rod 69 is provided between the decapitation limit plate 68 and the decapitation first splint 60. The decapitation clamping guide rods 69 are arranged at intervals. The decapitation limit plate 68 is fixedly connected to the telescopic rod of the decapitation splint driving cylinder 61. The decapitation limit plate 68 is provided with a rod through hole. The front end of the decapitation clamping guide rod 69 is fixedly connected to the decapitation first splint 60, and the rear end passes through the rod through hole on the decapitation limit plate 68 and is fixedly connected to the decapitation limit block 70. The decapitation clamping guide rod 69 is movably connected to the decapitation limit plate 68. A decapitation clamping spring 71 is sleeved on the decapitation clamping guide rod 69. One end of the decapitation clamping spring 71 abuts against the decapitation limit plate 68, and the other end abuts against the decapitation first splint 60, so as to support and limit the decapitation first splint through the decapitation clamping spring, enabling the decapitation first splint and the decapitation second splint to clamp squid heads of different sizes well.

[0035] As shown in the attached Figure 1 - attached Figure 7, a squid carrier 72 is fixedly arranged on the front side of the head-removing frame 50, and a squid carcass support mechanism 51 and a head-removing clamping mechanism 52 are arranged on the rear side. To further improve the efficiency of squid head removal, in this embodiment, two squid carriers 72 are arranged side by side on the front side of the head-removing frame 50. Correspondingly, two squid carcass brackets 56 and two squid head clamping spaces are arranged, which is convenient for tearing off the heads of two squids simultaneously at one time, with high working efficiency. The squid carrier 72, the squid carcass bracket 56, and the squid head clamping space correspond one by one, and the quantity can be set according to needs. The structure of the squid carrier 72 can refer to the limit fixing mechanism in the clamp, limit fixing mechanism and processing operation device with the patent number CN217609291U and the name of fixture, limit fixing mechanism and processing operation device applied by the applicant on July 27, 2022. The squid carrier 72 includes a support frame, a clamp is arranged on the support frame, a positioning groove is arranged at the rear end of the support frame, and the clamp is movably and limit-connected with the support frame. For specific content, refer to the above patent and will not be elaborated here. A control system can be arranged on the head-removing frame 50 of the present invention, such as a PLC control system. The squid carcass driving cylinder 54, the head-removing driving cylinder 59, and the head-removing clamping plate driving cylinder 61 are all connected to the control system and are driven by the control system. In the present invention, a slideway is fixed on the head-removing frame 50. Both ends of the head-removing guide rod 66 are fixedly connected to the head-removing frame 50 through connecting seats. The head-removing guide seat 65 is sleeved on the head-removing guide rod 66 and is slidably connected with the head-removing guide rod 66. The head-removing guide seat 65 is fixedly connected to the head-moving frame 58. The forward and backward movement of the squid carcass moving frame 53 is guided by the slideway, and the forward and backward movement of the head-removing moving frame 58 is guided by the head-removing guide seat 65 and the head-removing guide rod 66. The present invention also arranges a squid head clamping mechanism 67. When the head-removing first clamping plate 60 and the head-removing second clamping plate 62 are close to clamping the squid head, there is a head-removing clamping spring 71 between the head-removing first clamping plate 60 and the head-removing limit plate 68. Through the resilience of the head-removing clamping spring 71, a clamping force is given to the head-removing first clamping plate 60, so that the head-removing first clamping plate 60 and the head-removing second clamping plate 62 can clamp the squid head well. At the same time, the head-removing clamping spring 71 has a buffering effect, so that the size of the squid clamping space formed by the head-removing second clamping plate 62 and the head-removing first clamping plate 60 can be adjusted according to the size of the squid head, and thus different-sized squids can be clamped well. The head-removing clamping spring 71 is guided by the head-removing clamping guide rod 69. The rear end of the head-removing clamping guide rod 69 is fixedly connected to the head-removing limit block 70. The outer diameter of the head-removing limit block 70 is larger than the inner diameter of the rod through hole on the head-removing limit plate 68. The head-removing limit block 70 is fixedly connected to the head-removing clamping guide rod 69. In this way, the head-removing clamping guide rod 69 can be limited to prevent the head-removing clamping guide rod 69 from separating from the head-removing limit plate 68. In the initial state, the squid carcass driving cylinder 54 is in a contracted state, driving the squid carcass moving frame 53 to drive the squid carcass support frame away from the squid carrier 72, and the support gear 57 is separated from and does not contact the support rack plate 55. The squid carcass support frame is in a horizontal state, and the height of the squid carcass bracket 56 is slightly higher than the height of the squid carrier 72, which is convenient for inserting into the squid carcass.The head-removing driving cylinder 59 is in the extended state. The second head-removing clamping plate 62 is located below the positioning groove at the rear end of the squid carrier 72. After ensuring that the squid head naturally droops, the squid head is located at the rear side of the second head-removing clamping plate 62. The lower end of the squid carrier 72 can be fixedly connected to the head-removing frame 50 through a bracket. When the squid carcass supports the squid carcass, as shown in the attachment, Figure 1 and the attachment Figure 7 , the squid carcass support 56 is in a vertical state. The squid carcass support 56 is in an inverted V shape. The upper end of the squid carcass support 56 is arc-shaped. The two ends of the squid carcass support 56 open downward in a flared shape. This shape of the squid carcass support 56 matches the internal structure of the squid carcass, facilitating the support of the squid carcass without scratching the inner wall of the squid. After the squid carcass support 56 supports the squid carcass in a vertical state, the first head-removing clamping plate 60 and the second head-removing clamping plate 62 clamp the squid head and move backward to tear the squid head off the squid carcass, just like manually tearing off the squid head. The squid head structure is complete, and the squid carcass structure is also complete. The head-removing efficiency is high, indirectly reducing the cost of squid head-removing.

[0036] Due to the adoption of the above structure, the present invention has the advantages of ingenious structure, the separation of the squid head and the squid carcass by tearing, the complete structure of the squid head, high head-removing efficiency, and low head-removing cost.
