Description

Technical Field

[0001] This invention relates to the field of seafood processing equipment technology, specifically to a squid finning 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, fins, and body, 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 clamping device, a claw-opening mechanism, a main support mechanism, a clamping mechanism, a 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. The clamping device is located above the claw mechanism. The claw mechanism includes a clamping pincer, 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 clamping pincer to move closer to or further away from the first and second support rods. The first and second support rods are connected to the main support mechanism. When the clamping pincer 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 for... The main support mechanism clamps or releases the squid's head, and drives the claw mechanism and 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 off the squid's viscera when the clamping pincers, the first support rod, and the second support rod open the inner wall of the squid's body. The squid head cutting device is located on the other side of the main support mechanism and is used to cut off the squid's head when the first clamping plate and the second clamping plate clamp it. The squid fin removal device is used to remove the two fins of the squid to be processed. The squid clamping device includes a track and multiple railcars, each of which is suspended below the track and adapted to move on the track. Each railcar is equipped with a squid fin clamp for clamping the two fins of the squid to be processed. A squid fin removal device is located below the track and is vertically movable. The squid fin removal device includes a cutter, a first pressure plate, a second pressure plate, and a motor. The first and second pressure plates are arranged parallel to each other. The cutter is connected to the side of the second pressure plate facing the first pressure plate. The motor is connected to the first pressure plate and is used to move the first pressure plate closer to or away from the second pressure plate.When the first pressure plate approaches the second pressure plate, it clamps the squid fins of the railcar in the middle, and the cutter cuts off the two fins of the squid to be processed.

[0003] The aforementioned patent has several substantive shortcomings: First, according to the patent's description, when removing the squid's fins, the patent uses fin clips to hold the squid's fins. Then, the fin-cutting device rises, the fin clips enter between the first and second pressure plates, and the motor of the device drives the first pressure plate towards the second pressure plate. During this movement, the first pressure plate presses tightly against the back of the fin clips, restricting the squid's movement, and presses against the second pressure plate equipped with a cutter to cut the fins. The fin-cutting device then moves downwards, tearing away any remaining uncut fins. However, there is no clear dividing line between the fins and the squid's body; it uses a method of cutting and then tearing. There are two main methods. One method involves cutting the squid fins directly onto the squid's body, resulting in incomplete fin structures and wasted fins. Furthermore, the fins adhere to the body, requiring secondary processing, which is time-consuming and laborious. The other method uses a first pressure plate pressed against the back of the fin clip, then a second pressure plate with a cutter to cut the fin. However, this method doesn't guarantee a cut along the natural separation line between the fin and body. Normally, tearing the fin along this line is easier, but incorrect cutting direction makes tearing difficult and can easily damage the fin, causing it to break. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a squid fin removal device that is ingeniously structured, allows for rapid squid fin removal, preserves the integrity of the squid fin structure, and saves time and effort.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A squid defining device includes a squid defining frame and a squid carrier. The squid carrier is located at the front end of the squid defining frame, and the lower end of the squid carrier is fixedly connected to the squid defining frame via a bracket. The device is characterized by: a squid supporting mechanism located behind the squid carrier; a squid pressing and limiting mechanism located above the squid carrier; and a squid defining mechanism located in front of the squid carrier. The squid supporting mechanism, the squid pressing and limiting mechanism, and the squid defining mechanism are respectively connected to the squid defining frame to facilitate the following: the squid supporting mechanism lifts the squid from the squid carrier; the squid defining mechanism moves to below the squid fins; the squid supporting mechanism lowers the squid; the squid pressing and limiting mechanism presses down on the squid; and the squid defining mechanism moves forward to remove the squid fins.

[0007] The squid supporting mechanism of this invention includes a squid supporting plate, a squid supporting seat, a guide slider, a squid supporting moving cylinder, a guide supporting block, and a squid supporting frame. The squid supporting plate is located at the rear of the squid carrier. The front end of the squid supporting plate extends towards the squid carrier to form a squid carcass insertion supporting end. The rear end of the squid supporting plate is located at the squid supporting seat. The squid supporting plate and the squid supporting seat are hinged together. A guide slider is located at the lower end of the squid supporting plate.

[0008] Below the squid support is a squid support frame, and in front of the squid support is a guide support block. The squid support is slidably connected to the squid support frame via a guide rod and a guide seat. The squid support is driven by a squid support moving cylinder. The squid support moving cylinder, the squid support frame, and the squid finning machine frame are fixedly connected. The lower end of the guide support block is fixedly connected to the squid support frame. The height of the upper surface of the guide support block is higher than the height of the lower surface of the guide slider. The lower end of the guide slider moves in coordination with the guide support block. The upper end of the guide slider is fixedly connected to the squid support plate, so that the squid support plate can be moved forward by the squid support moving cylinder. The front end of the squid support plate extends into the squid body on the squid carrier. As the squid support plate moves forward, the lower end of the guide slider moves in coordination with the guide support block. The guide slider drives the guide support block to rotate upward, so that the squid support plate carries the squid body upward and detaches from the squid carrier.

[0009] The lower end face of the guide slider of the present invention is arc-shaped, the rear side of the guide support block is provided with a guide slope, the upper end face of the guide support block is a guide plane, the guide slope slopes from back to front and upward, and the upper end of the guide slope naturally transitions to connect with the guide plane, so as to facilitate the guide slider to gradually move from the guide slope to the guide plane, increase the height of the guide slider, and thus make the squid support plate lift forward and upward, and take the squid away from the surface of the squid carrier.

[0010] The guide slider of the present invention is provided with a roller at its lower end. The roller is movably sleeved on the roller shaft, and the roller shaft is fixedly connected to the guide slider. The roller is rotatably connected to the guide support block. The guide support block is provided with a guide slope on its rear side, and the upper end surface of the guide support block is a guide plane. The guide slope slopes from back to front and upward, and the upper end of the guide slope naturally transitions to connect with the guide plane, so as to facilitate the guide slider to gradually move from the guide slope to the guide plane, increase the height of the guide slider, and thus make the squid support plate lift forward and upward, bringing the squid away from the surface of the squid carrier.

[0011] The present invention provides a supporting and stabilizing mechanism between the squid support plate and the squid support base. The supporting and stabilizing mechanism includes a support plate, a support adjustment spring, and a buffer. The support plate is located below the rear end of the squid support plate and is hinged to the rear end of the support plate. A support adjustment spring is located between the front end of the support plate and the squid support plate. A buffer is located on the support plate. The support plate is fixedly connected to the squid support base. One end of the support adjustment spring is fixedly connected to the squid support plate, and the other end is fixedly connected to the support plate. The buffer is fixed to the support plate, and its upper end abuts against the squid support plate. This facilitates the support of the squid support plate by the buffer and the support adjustment spring, allowing the squid support plate to enter the squid body horizontally. At the same time, the buffer and the support adjustment spring ensure that the squid support plate is stable and does not wobble when supporting the squid.

[0012] The squid pressing and limiting mechanism of the present invention includes a squid pressing plate and a squid pressing drive cylinder. The squid pressing plate is provided above the squid carrier. The squid pressing plate is inclined from back to front and downward. The squid pressing plate is driven by the squid pressing drive cylinder. The squid pressing drive cylinder is fixedly connected to the squid defining machine frame via a bracket, so as to facilitate the squid pressing plate to press the squid by driving the squid pressing drive cylinder, so that the squid carcass will not move when the squid is defining.

[0013] The squid pressing plate of this invention is provided with a squid pressing component, which includes a squid pressing support plate, a pressing guide rod, and a pressing spring. The squid pressing support plate is located above the squid pressing plate, and a pressing guide rod is provided between the squid pressing plate and the squid pressing support plate. The rear end of the squid pressing plate is hinged to the squid pressing support plate. The squid pressing support plate is fixedly connected to the telescopic rod of the squid pressing drive cylinder. The squid pressing support plate is provided with a guide rod hole. The lower end of the pressing guide rod is fixedly connected to the squid pressing plate, and the upper end passes through the guide rod hole and is limited and fixed by a limiting block. A pressing spring is sleeved on the pressing guide rod. One end of the pressing spring abuts against the squid pressing plate, and the other end abuts against the squid pressing support plate, so that when the squid is pressed down by the squid pressing plate, the pressing spring is squeezed, and the pressing spring generates a rebound force, driving the squid pressing plate to press the squid more tightly and closely.

[0014] The squid finning mechanism of this invention includes a finning knife and a finning knife moving cylinder. The finning knife is located at the front of the squid carrier, and the finning knife has a finning blade opening in the middle. The finning blade opening opens in a trumpet shape from back to front and to both sides. The finning knife is driven by the finning knife moving cylinder, which is fixedly connected to the squid finning machine frame via a bracket. This facilitates the finning knife being driven to move backward and positioned under the squid by the finning knife moving cylinder. Under its own gravity, the squid fin falls below the finning blade opening, and the finning knife moving cylinder moves forward, causing the finning blade opening to remove the squid fin.

[0015] The squid carrier of the present invention is equipped with a clamp, which is movably connected to the squid carrier via a clamp adjustment mechanism. A squid release and fixation mechanism is provided below the squid carrier. The squid release and fixation mechanism includes a release plate and a release drive cylinder. The release plate is provided at the front of the clamp adjustment mechanism and abuts against the clamp adjustment mechanism. The release plate is driven by the release drive cylinder, which drives the release plate to move back and forth. The release drive cylinder is fixedly connected to the squid fin removal machine frame via a bracket, so as to facilitate the clamp adjustment mechanism to move backward through the release plate, thereby driving the clamp to move backward away from the squid fin and releasing the limitation and fixation on the squid.

[0016] The present invention, due to the above-mentioned structure, has the advantages of ingenious structure, rapid removal of squid fins, intact squid fin structure, and saving time and effort. Attached Figure Description

Detailed Implementation

[0024] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] A squid defining device includes a squid defining frame 80 and a squid carrier 81. The squid carrier 81 is located at the front end of the squid defining frame 80, and the lower end of the squid carrier 81 is fixedly connected to the squid defining frame 80 via a bracket. The device is characterized in that: a squid supporting mechanism 82 is located behind the squid carrier 81; a squid pressing and limiting mechanism 83 is located above the squid carrier 81; and a squid defining mechanism 84 is located in front of the squid carrier 81. The squid supporting mechanism 82, the squid pressing and limiting mechanism 83, and the squid defining mechanism 84 are respectively connected to the squid defining frame 80 to facilitate the following: the squid supporting mechanism lifts the squid on the squid carrier; the squid defining mechanism moves to below the squid fins; the squid supporting mechanism lowers the squid; then the squid pressing and limiting mechanism presses down on the squid; and the squid defining mechanism moves forward to remove the squid fins.

[0026] The squid support mechanism 82 of the present invention includes a squid support plate 85, a squid support seat 86, a guide slider 87, a squid support moving cylinder 88, a guide support block 89, and a squid support frame 90.

[0027] A squid support plate 85 is provided at the rear of the squid carrier 81. The front end of the squid support plate 85 extends towards the squid carrier 81 to form a squid carcass insertion support end. A squid support seat 86 is provided at the rear end of the squid support plate 85. The squid support plate 85 and the squid support seat 86 are hinged together. A guide slider 87 is provided at the lower end of the squid support plate 85. A squid support frame 90 is provided below the squid support seat 86. A guide support block 89 is provided in front of the squid support seat 86. A guide rod 91 is provided on the squid support frame 90. The guide rod 91 is fixedly connected to the squid support frame 90 via a support rod. A guide seat 92 is sleeved on the guide rod 91 and slidably connected to the guide rod 91. The guide seat 92 is fixedly connected to the squid support seat 86. The squid support seat 86 is supported by a squid support moving cylinder. Driven by 88, the squid support moving cylinder 88, the squid support frame 90, and the squid finning machine frame 80 are fixedly connected. The lower end of the guide support block 89 is fixedly connected to the squid support frame 90. The height of the upper surface of the guide support block 89 is higher than the height of the lower surface of the guide slider 87. The lower end of the guide slider 87 moves in coordination with the guide support block 89. The upper end of the guide slider 87 is fixedly connected to the squid support plate 85, so as to facilitate the squid support seat to move forward through the squid support moving cylinder, and the front end of the squid support plate extends into the squid body on the squid carrier. As the squid support plate moves forward, the lower end of the guide slider moves in coordination with the guide support block. The guide slider drives the guide support block to rotate upward, so that the squid support plate carries the squid body upward and separates from the squid carrier.

[0028] The lower end face of the guide slider 87 of the present invention is arc-shaped, and the rear side of the guide support block 89 is provided with a guide slope 93. The upper end face of the guide support block 89 is a guide plane 94. The guide slope 93 is inclined from back to front and upward. The upper end of the guide slope 93 is naturally connected to the guide plane 94 to facilitate the guide slider to gradually move from the guide slope to the guide plane, increase the height of the guide slider, and thus make the squid support plate lift forward and upward, taking the squid away from the surface of the squid carrier.

[0029] The guide slider 87 of the present invention is provided with a roller at its lower end. The roller is movably sleeved on the roller shaft. The roller shaft is fixedly connected to the guide slider 87. The roller is rotatably connected to the guide support block 89. The guide support block 89 is provided with a guide slope 93 on its rear side. The upper end surface of the guide support block 89 is a guide plane 94. The guide slope 93 is inclined from back to front and upward. The upper end of the guide slope 93 naturally transitions to connect with the guide plane 94, so as to facilitate the guide slider to gradually move from the guide slope to the guide plane, increase the height of the guide slider, and thus make the squid support plate lift forward and upward, bringing the squid away from the surface of the squid carrier.

[0030] The present invention provides a supporting and stabilizing mechanism 95 between the squid support plate 85 and the squid support base 86. The supporting and stabilizing mechanism 95 includes a supporting plate 96, a supporting adjustment spring 97, and a buffer 98. The supporting plate 96 is located below the rear end of the squid support plate 85, and its rear end is hinged to the squid support plate 85. A supporting adjustment spring 97 is located between the front end of the supporting plate 96 and the squid support plate 85. A buffer 98 is provided on the supporting plate 96. The plate 96 is fixedly connected to the squid support seat 86. One end of the support adjustment spring 97 is fixedly connected to the squid support plate 85, and the other end is fixedly connected to the support plate 96. The buffer 98 is fixed on the support plate 96. The upper end of the buffer 98 abuts against the squid support plate 85 to facilitate the support of the squid support plate by the buffer and the support adjustment spring, so that the squid support plate enters the squid body horizontally. At the same time, the buffer and the support adjustment spring ensure that the squid support plate is stable and does not shake when supporting the squid.

[0031] The squid pressing and limiting mechanism 83 of the present invention includes a squid pressing plate 99 and a squid pressing drive cylinder 100. The squid pressing plate 99 is provided above the squid carrier 81. The squid pressing plate 99 is inclined from back to front and downward. The squid pressing plate 99 is driven by the squid pressing drive cylinder 100. The squid pressing drive cylinder 100 is fixedly connected to the squid finning machine frame 80 via a bracket, so as to facilitate the squid pressing plate to press the squid by driving the squid pressing drive cylinder, so that the squid carcass will not move when the squid is finned.

[0032] The squid pressing plate 99 of the present invention is provided with a squid pressing component 101. The squid pressing component 101 includes a squid pressing support plate 102, a pressing guide rod 103, and a pressing spring 104. The squid pressing support plate 102 is provided above the squid pressing plate 99. A pressing guide rod 103 is provided between the squid pressing plate 99 and the squid pressing support plate 102. The rear end of the squid pressing plate 99 is hinged to the squid pressing support plate 102. The squid pressing support plate 102 is fixedly connected to the telescopic rod of the squid pressing drive cylinder 100. The squid pressing support plate 102 is provided with a guide rod hole. The lower end of the guide rod 103 is fixedly connected to the squid pressing plate 99, and the upper end passes through the guide rod hole and is fixed by a limiting block. The limiting block is fixedly connected to the pressing guide rod 103. The outer diameter of the limiting block is larger than the inner diameter of the guide rod hole to prevent the upper end of the pressing guide rod from sliding out of the squid pressing support plate. A pressing spring 104 is sleeved on the pressing guide rod 103. One end of the pressing spring 104 abuts against the squid pressing plate 99, and the other end abuts against the squid pressing support plate 102. This allows the pressing spring to be squeezed when the squid is pressed down by the squid pressing plate. The pressing spring generates a rebound force, which drives the squid pressing plate to press the squid more tightly and closely.

[0033] The squid finning mechanism 84 of the present invention includes a finning knife 105 and a finning knife moving cylinder 106. The finning knife 105 is provided in front of the squid carrier 81. The finning knife 105 has a finning opening 107 in the middle. The finning opening 107 opens in a trumpet shape from back to front and to both sides. The finning knife 105 is driven by the finning knife moving cylinder 106. The finning knife moving cylinder 106 is fixedly connected to the squid finning machine frame 80 via a bracket, so as to facilitate the finning knife to move backward and be placed under the squid by driving the finning knife moving cylinder. The squid fin falls under the finning opening under its own gravity. The finning knife moving cylinder moves forward and the finning opening removes the squid fin.

[0034] The squid carrier 81 of the present invention is provided with a clamp 108. The clamp 108 is movably connected to the squid carrier 81 via a clamp adjustment mechanism 109. A squid release and fixation mechanism 110 is provided below the squid carrier 81. The squid release and fixation mechanism 110 includes a release plate 111 and a release drive cylinder 112. The release plate 111 is provided on the front side of the clamp adjustment mechanism 109. The release plate 111 abuts against the clamp adjustment mechanism 109. The release plate 111 is driven by the release drive cylinder 112. The release drive cylinder 112 drives the release plate 111 to move back and forth. The release drive cylinder 112 is fixedly connected to the squid fin removal machine frame 80 via a bracket, so as to facilitate the clamp adjustment mechanism to move backward through the release plate, thereby moving the clamp backward away from the squid fin and releasing the limitation and fixation on the squid.

[0035] As attached Figure 1 -Appendix Figure 6A squid carrier 81 is provided on the front side of the frame. The structure of the squid carrier 81 can be referred to in 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 81 includes a support frame, a clamp on the support frame, a positioning groove at the rear end of the support frame, a movable plate fixed on the clamp, and a guide hole on the support frame. The movable plate cooperates with the guide hole of the support frame. An adjustment mechanism is provided at the lower end of the movable plate through the guide hole. The adjustment mechanism is connected to the support frame. The adjustment mechanism can drive the two movable plates to move the clamp relative to the support frame. Pulling the adjustment mechanism backward can move the clamp backward and release the squid. The clamp on the squid carrier 81 is the clamp 108 mentioned in this invention, and the adjustment mechanism is the clamp adjustment mechanism 109 mentioned in this invention. For details, please refer to the above patent. It will not be repeated here. To improve finning efficiency, the squid finning device in this embodiment includes two sets of clamps 108, corresponding to two support plates 96, two squid pressing plates 99, and two finning knives 105. The two finning knives 105 can be fixed to the finning knife holder, which is driven by the finning knife moving cylinder 106. The finning knife holder can be guided and moved via guide rods and guide seats. Specifically, the squid support seat 86 is slidably connected to the squid support frame 90 via guide rods 91 and guide seats 92. The release plate 111 can be a single, wide piece that can simultaneously move the adjustment mechanisms at the lower ends of the two squid carriers 81 backward, releasing the squid from fixation. The number of squid carriers 81 is set according to requirements, and other structures are set accordingly. A control system can be installed on the squid finning frame 80 of this invention. The squid support moving cylinder 88, squid pressing drive cylinder 100, finning knife moving cylinder 106, and release drive cylinder 112 are all controlled by the control system. In the initial state, as shown in the attached... Figure 1 and attached Figure 3 When the squid supports the moving cylinder 88, it is in the extended state; when the squid presses the driving cylinder 100, it is in the retracted state; when the fin-removing moving cylinder 106 is in the extended state; and when the driving cylinder 112 is released, it is in the extended state. In use, the squid carrier 81 of this invention may or may not be equipped with clamps 108. Depending on whether the squid carrier 81 has clamps 108, there are two methods for removing the squid's fins. Specifically:

[0036] When the squid carrier 81 does not have the clamp 108, that is, when the squid carrier 81 is just a support platform, it is suitable for defining squid alone. The method for defining squid is as follows:

[0037] Step 1: Place the squid on the squid carrier 81 with the squid fins facing forward and the squid head facing backward;

[0038] Step 2: Activate the squid lifting cylinder 88, retract the squid lifting cylinder 88, drive the lifting support plate 96 to move forward, and extend the front end of the squid lifting plate 85 from between the squid head and the squid body into the squid body on the squid carrier 81. As the squid lifting plate 85 moves forward, the guide slider 87 at the lower end of the squid lifting plate 85 contacts the guide slope 93 of the guide lifting block 89, and gradually moves forward and upward from the guide slope 93 to the guide plane 94 of the guide lifting block 89. The front end of the squid lifting plate 85 is then lifted upward, taking the squid away from the upper surface of the squid carrier 81, and the squid lifting cylinder 88 is closed.

[0039] Step 3: Start the fin-removing cylinder 106, the telescopic rod of the fin-removing cylinder 106 retracts, driving the fin-removing blade 105 to move backward. After the fin-removing blade 105 moves above the squid carrier 81, it stops. Then, turn off the fin-removing cylinder 106.

[0040] Step 4: Activate the squid lifting cylinder 88. The telescopic rod of the squid lifting cylinder 88 extends, driving the lifting support plate 96 to move backward. The guide slider 87 at the lower end of the squid lifting plate 85 moves backward along the guide plane 94 of the guide lifting block 89 and towards the guide slope 93 until the guide slider 87 disengages from the guide lifting block 89. At the same time, the front end of the squid lifting plate 85 rotates downward, placing the squid onto the squid carrier 81. The part of the squid with fins rests on the fin-removing knife. On 105, under the action of its own gravity, the squid's two fins move downward from the fin-removing cut 107 of the fin-removing knife 105, and the squid's two fins fall onto the squid carrier 81 through the fin-removing cut 107. That is, the fin-removing cut 107 of the fin-removing knife 105 is placed between the squid's two fins and the squid's body. The squid support plate 85 continues to move backward, and the squid support plate 85 is removed from the squid's body. The squid support plate 85 returns to its original position, and the squid support moving tank 88 is closed.

[0041] Step 5: Activate the squid pressing drive cylinder 100. The telescopic rod of the squid pressing drive cylinder 100 extends, and the squid pressing plate 99 moves downward. The squid pressing plate 99 presses down on the squid body, so that the squid body is close to the squid carrier 81. Under the action of the pressing spring 104, the squid pressing plate 99 presses down firmly on the squid body.

[0042] Step 6: Start the fin-removing moving cylinder 106. The telescopic rod of the fin-removing moving cylinder 106 extends, driving the fin-removing knife 105 to move forward. The fin-removing blade 107 of the fin-removing knife 105 moves forward to cut off the two fins of the squid. The fin-removing knife 105 continues to move forward and returns to its original position. Then, the fin-removing moving cylinder 106 is turned off.

[0043] Step 7: Remove the squid carcass, collect the squid fins, and complete the squid fin removal process.

[0044] When the squid carrier 81 is equipped with a clamp 108, which is the structure of the limiting and fixing mechanism in patent CN217609291U, the squid carrier 81 is equipped with a clamp 108. The clamp 108 is movably connected to the squid carrier 81 through a clamp adjustment mechanism 109. When the squid is placed on the squid carrier 81, the clamp 108 can hold the squid body. At the same time, the clamp 108 can limit the squid fins from moving towards the squid head. Therefore, when removing the squid fins, it is necessary to first release the squid from the fixation, as shown in the attached diagram. Figure 1 Appendix Figure 2 and attached Figure 4 This invention includes a squid release and fixing mechanism 110. A release plate 111 is slidably connected to the squid defining machine frame 80 via a guide rod and guide seat. The release plate 111 is driven by a release drive cylinder 112. Located below the squid carrier 81 and in front of the clamp adjustment mechanism 109, the release plate 111 moves backward, pushing the clamp adjustment mechanism 109 backward, which in turn moves the clamp 108 backward, freeing the squid fins from the clamp 108's restriction. At this point, the squid lifting plate 85 can be inserted into the squid's body to lift the squid. This structure is suitable for both individual squid defining operations and continuous squid processing, such as head, fin, and ear removal. When the clamp 108 is installed on the squid carrier 81, the squid defining method is as follows:

[0045] Step 1: Place the squid on the support frame of the squid carrier 81 with the squid head facing backward and the squid fins facing forward. The squid's body is inserted into the clamping groove of the clamp 108 on the squid carrier 81. The squid's two tail fins are placed behind the clamp 108. The clamp 108 limits the squid's two tail fins so that the squid cannot move backward.

[0046] Step 2: Activate the squid support cylinder 88, which retracts and drives the support plate 96 to move forward. The front end of the squid support plate 85 extends from between the squid head and the squid body into the squid body on the squid carrier 81. At the same time, activate the release drive cylinder 112, which drives the release plate 111 to move backward. The release plate 111 drives the clamp adjustment mechanism 109 to move backward, which in turn drives the clamp 108 to move backward, releasing the limitation and fixation on the squid. As the squid support plate 85 moves forward, the guide slider 87 at the lower end of the squid support plate 85 contacts the guide slope 93 of the guide support block 89 and gradually moves forward and upward from the guide slope 93 to the guide plane 94 of the guide support block 89. The front end of the squid support plate 85 is then lifted upward, taking the squid away from the upper surface of the squid carrier 81. Then, the squid support cylinder 88 is closed.

[0047] Step 3: Start the fin-removing cylinder 106, the telescopic rod of the fin-removing cylinder 106 retracts, driving the fin-removing blade 105 to move backward. After the fin-removing blade 105 moves above the squid carrier 81, it stops. Then, turn off the fin-removing cylinder 106.

[0048] Step 4: Activate the squid lifting cylinder 88. The telescopic rod of the squid lifting cylinder 88 extends, driving the lifting support plate 96 to move backward. The guide slider 87 at the lower end of the squid lifting plate 85 moves backward along the guide plane 94 of the guide lifting block 89 and towards the guide slope 93 until the guide slider 87 disengages from the guide lifting block 89. At the same time, the front end of the squid lifting plate 85 rotates downward, placing the squid onto the squid carrier 81. The part of the squid with fins rests on the fin-removing knife. On 105, under the action of its own gravity, the squid's two fins move downward from the fin-removing cut 107 of the fin-removing knife 105, and the squid's two fins fall onto the squid carrier 81 through the fin-removing cut 107. That is, the fin-removing cut 107 of the fin-removing knife 105 is placed between the squid's two fins and the squid's body. The squid support plate 85 continues to move backward, and the squid support plate 85 is removed from the squid's body. The squid support plate 85 returns to its original position, and the squid support moving tank 88 is closed.

[0049] Step 5: Activate the squid pressing drive cylinder 100. The telescopic rod of the squid pressing drive cylinder 100 extends, and the squid pressing plate 99 moves downward. The squid pressing plate 99 presses down on the squid body, so that the squid body is close to the squid carrier 81. Under the action of the pressing spring 104, the squid pressing plate 99 presses down firmly on the squid body.

[0050] Step 6: Start the fin-removing moving cylinder 106. The telescopic rod of the fin-removing moving cylinder 106 extends, driving the fin-removing knife 105 to move forward. The fin-removing blade 107 of the fin-removing knife 105 moves forward to cut off the two fins of the squid. The fin-removing knife 105 continues to move forward and returns to its original position. Then, the fin-removing moving cylinder 106 is turned off.

[0051] Step 7: Remove the squid carcass, collect the squid fins, and complete the squid fin removal process.

[0052] The above two operating methods can be selected and set according to the specific situation. The present invention has a simple structure and is easy to operate. The fin-removing knife can fit close to the connection between the squid fin and the squid body to remove the squid fin, thus maintaining the integrity of the squid fin and the squid body. Moreover, the fin removal efficiency is high and the operation is time-saving and labor-saving.

[0053] The present invention, due to the above-mentioned structure, has the advantages of ingenious structure, rapid removal of squid fins, intact squid fin structure, and saving time and effort.
