Fluid sandwich crab stick cutting device and cutting method

Abstract

The present invention discloses a fluid-stuffed crab stick cutting device and a cutting method thereof, and relates to the technical field of cutting devices. It comprises a cutting knife body, which is used for rotating and cutting the fluid-stuffed crab stick body. The cutting knife body comprises a scabbard part, a blade part and a carrying part. The blade part is integrated in the scabbard part, and is installed together outside the carrying part, and pops out only before cutting the fluid-stuffed crab stick body. During the cutting process of the present invention, the high temperature on the surface of the blade part when it pops out causes the protein in the outer layer of the surimi to denature and solidify quickly, forming a heat-sealing layer. At the same time, the low temperature emitted by the scabbard part acts on the filling fluid through the sheath mouth insulation layer, thereby increasing its viscosity. The dual temperature control mechanism effectively overcomes the problem of uneven shear stress wave transmission in the traditional cutting device, and reduces the leakage of the fluid sandwich in the fluid-stuffed crab stick.

Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, in particular to a fluid-stuffed crab stick cutting device and a cutting method thereof. Background Art

[0002] "Fluid-filled crab sticks" are an innovative food that combines traditional crab sticks (surimi products) with fluid fillings. They are commonly found in the catering industry or in creative home cooking. During their production, co-extrusion technology is often used to directly inject a fluid filling during the surimi molding process, and a cutting device is used to cut them to a fixed length. However, when dealing with such multi-layer composite structures, conventional cutting devices are prone to uneven shear stress, which can lead to filling leakage or surimi deformation, resulting in uneven product quality and affecting taste and appearance. To address this technical problem, the present invention proposes a fluid-filled food material device and a cutting method thereof.

[0003] After searching, the Chinese invention patent with publication number "CN113729178A" discloses "a crab stick demeshing and cutting device". The servo motor drives the cutting piece to rotate, so that the cutting piece cuts the crab stick during the rotation process. During the cutting process, since the blade of the cutting piece is arc-shaped, the cutting piece can cut the meat inside the crab stick without cutting the outer membrane of the crab stick.

[0004] In addition, the Chinese invention patent with publication number "CN117817736A" discloses "a cutting device for processing stuffed crab steaks". The swinging assembly drives the swinging frame and the extension frame to swing back and forth, so that the cutter can swing to cut the stuffed crab steaks conveyed to the carrying plate. After each cutting action on the stuffed crab steaks, the scraper assembly can drive the scraper sleeve to slide back and forth relative to the cutter once, so as to scrape off the stuffing paste on the cutter, effectively avoiding the stuffing paste splashing onto the surface of the stuffed crab steaks during the cutting process, and greatly improving the cutting quality of the stuffed crab steaks.

[0005] However, it should be noted that although the above two existing technologies and similar devices can achieve the cutting of crab sticks or the slicing of crab fillets, when faced with multi-layer composite structure ingredients such as fluid-stuffed crab sticks, due to the special combination of the fluid sandwich and the outer layer of the fish paste in the fluid-stuffed crab sticks, when processing the fluid-stuffed crab sticks, the fluid sandwich will seep out at the moment of cutting, thereby affecting the appearance and internal quality of the final product. In view of this, the present invention aims to design a cutting device specially customized for fluid-stuffed crab sticks. Summary of the Invention

[0006] The object of the present invention is to provide a fluid-stuffed crab stick cutting device and a cutting method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] In a first aspect, a fluid-filled crab stick cutting device is provided, comprising:

[0009] The cutting blade is used to rotate and cut the fluid-filled crab stick body;

[0010] The cutting blade body includes a scabbard, a blade, and a mounting portion. The blade is integrated into the scabbard and mounted outside the mounting portion. It pops out only before cutting the fluid-filled crab stick body. The scabbard and blade generate cold energy and heat energy respectively. During cutting, the heat energy on the surface of the blade accelerates the cutting of the fluid-filled crab stick body. The cold energy on the surface of the scabbard plasticizes the sandwich fluid in the fluid-filled crab stick body, ensuring a smooth cross-section of the fluid-filled crab stick body and sealing the internal fluid.

[0011] The mounting parts include:

[0012] A collar box is provided with an energy supply component capable of transmitting electric current installed around its periphery. Two collar boxes are provided.

The contact surfaces of the two collar boxes are fixed to each other. The other surfaces of the two collar boxes are used to receive electric energy. The ring openings in the collar boxes are used to receive rotational energy.

[0013] A trigger sleeve is inserted into the ring box for installing the blade part, and its position is fixed in the ring box by means of an external connector. A raised contact ball is fixed on the outside of the trigger sleeve. During the rotation of the ring box for installing the blade part, the bottom of the blade part pops out from the scabbard part by contacting the contact ball.

The folded end of the connecting folding rod is fixed to the surface of the blade.

[0018] The outer surface of the collar box on which the scabbard piece is mounted is directly fixed to the bottom end of the scabbard piece.

[0019] As a further preferred embodiment of the present technical solution, there is an electrical connection between the energy supply component and the transmission assembly. The structure of the energy supply component presents differentiated characteristics due to the installation requirements of the blade component and the scabbard component. When the blade component is adapted, the composition structure of the energy supply component includes:

[0020] The functional seat has a rod-shaped interface adapted to the insertion rod, and the rod-shaped interface has a characteristic quantity that distinguishes the adaptive energy supply assembly of the scabbard part and the blade part;

[0021] The functional seat forms a sliding fit with the slide rail outside the cover through a slide groove set on one side of the bottom, and the other side of the bottom of the functional seat is rigidly connected to the ring box through a conductive arm. The surface of the ring box is integrated with a conductive cover that forms a conductive loop with the conductive arm, and there is an electrical connection between the conductive cover and the transmission assembly.

[0022] As a further preferred embodiment of the present invention, the scabbard component includes:

[0023] The scabbard has an outer edge at the scabbard opening and an insulating layer at the inner edge thereof, the insulating layer being used to isolate the temperature exchange between the scabbard and the blade. An arc-shaped notch is provided at the central axis of one side of the scabbard surface and is curved along the scabbard opening, and the arc-shaped notch is adapted to the connecting folding rod.

[0024] The blade member comprises:

[0025] The blade is slidably connected in the scabbard, the edge of the blade is aligned with the scabbard opening, the back edge of the blade is fixed with a contact frame, and the surface of the contact frame is fixed to the connecting folding rod.

[0026] As a further preferred embodiment of the present invention, the transmission assembly includes:

[0027] The main transmission shaft and the secondary transmission shaft are respectively inserted into the interiors of the two collar boxes, wherein the secondary transmission shaft is installed in the collar box equipped with the blade member, and one end of the secondary transmission shaft is hinged to one end of the main transmission shaft, and the outer periphery of one end of the secondary transmission shaft is fixed to the inner wall of one end of the trigger sleeve, and the other end of the trigger sleeve does not contact the inner wall of the collar box equipped with the blade member;

[0028] The surface of one end where the main transmission shaft and the secondary transmission shaft are in contact is fixed to the inner wall of the ring opening of the ring box on which the scabbard part is installed, and the other end of the main transmission shaft and the other end of the secondary transmission shaft are commonly fixed to two ends installed on the inner wall of the assembly component.

[0029] As a further preferred embodiment of the present invention, the main transmission shaft and the secondary transmission shaft are both covered with a conductive tube, one end of the conductive tube is fixed to the inner wall of the assembly component, and the outside of the conductive tube is covered with an insulating cover;

[0030] The conductive tube is placed on the cover body and an energy supply seat is installed. A rigid connecting conductive bundle is installed between the energy supply seat and the conductive cover.

[0031] As a further preferred embodiment of the present invention, the assembly component includes:

[0032] A connecting frame is fixedly attached to one end of the outer side of the crab stick conveyor, one side of the top of the inner wall of the connecting frame is fixedly connected to the secondary transmission shaft, and a servo motor is installed on the other side of the top of the inner wall of the connecting frame. The shaft of the servo motor passes through the connecting frame and is fixed to one end of the main transmission shaft;

[0033] A splash-proof arc plate for covering the outside of the crab stick conveyor is laid and fixed on the surface of the connecting frame near the position of the crab stick conveyor. A retention gap is left between the two splash-proof arc plates to allow the cutting knife body to rotate. A reinforcing arm is fixed to the bottom end of the inside of the connecting frame and is attached to the bottom of one end of the outer side of the crab stick conveyor.

[0034] Secondly, in order to improve the above technical solution, a cutting method of a fluid-stuffed crab stick cutting device is also proposed, using a fluid-stuffed crab stick cutting device described in any one of the above disclosures.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] The fluid-filled crab stick cutting device and cutting method thereof, during the cutting process, the high temperature on the surface of the blade when it is ejected causes the protein in the outer layer of the surimi to quickly denature and solidify, forming a heat-sealing layer. At the same time, the low temperature emitted by the scabbard acts on the filling fluid through the scabbard opening insulating layer, increasing its viscosity. The dual temperature control mechanism effectively overcomes the problem of uneven shear stress wave transmission in traditional cutting devices, and reduces leakage of the fluid filling in the fluid-filled crab stick.

[0037] In addition, when the secondary drive shaft triggers the blade through the contact ball to complete the ejection-cutting and reset action cycle under the action of the return spring, the phase lag problem in the rotary cutting process is guaranteed, which improves the processing efficiency to a certain extent.

[0038] It should also be added that through the linkage between the transmission assembly and the servo motor shaft, while the crab stick conveyor transports the fluid-stuffed crab stick body at a uniform speed, the trigger sleeve forms a periodic trigger signal through the centrifugal force generated by the rotation of the ring box and the collision contact with the contact ball, causing the blade to pop out when the cutting phase angle reaches the preset position, ensuring the uniformity of the cutting spacing of each section.

DETAILED DESCRIPTION

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] Before understanding the technical solution proposed in the present application, it should be clear that in the present application, the heating and cooling principles of the blade and scabbard parts are respectively realized through the electrical connection between the energy supply component and the conductive tube 502. Specifically, a semiconductor heating element is provided in the functional seat 608 for installing the blade part, which receives the pulse current conducted by the conductive tube 502 through the conductive arm 602, so that the surface of the blade part has the ability to heat up. The functional seat 608 for installing the scabbard part is integrated with a micro compressor refrigeration module, and the power supply circuit of the conductive arm 602 maintains the surface temperature of the scabbard part in the range of -5°C to 5°C. It should be noted that in the present application, since the semiconductor heating element and the micro compressor refrigeration module are both common devices in the prior art, they are integrated in the functional seat 608 and are not displayed separately.

[0053] It should also be noted that in this application, the insulation layer within the scabbard is constructed from a nano-ceramic composite material with a thermal conductivity coefficient of less than 0.8 W / (m·K). This allows for a temperature gradient exceeding 100°C / mm when the distance between the scabbard 603 and the blade 609 is 0.2-0.5 mm. When the transmission assembly 5 rotates the cutting blade 6, each time the trigger sleeve 505 reaches a phase angle where it collides with the contact ball, the blade ejects from the scabbard, completing the cutting action. The high temperature of the blade 609 creates a dense, coagulated protein layer on the surface of the surimi, while the low temperature of the scabbard 603 increases the viscosity of the filling fluid, achieving a dual curing effect of "heat sealing and condensation."

[0054] It should be further explained that when the servo motor 305 drives the main transmission shaft 503 to rotate, the positive current forms a heating circuit through the conductive tube 502 → the energy supply seat 506 → the conductive cover 605 → the conductive arm 602, while the cooling circuit of the scabbard is realized through an independently laid Freon circulation pipeline, which is arranged on the inner wall of the scabbard 603 to form a closed-loop cooling system.

[0055] like Figures 1-11 As shown, the present invention provides a technical solution: a fluid sandwich crab stick cutting device, comprising:

[0056] The cutting blade 6 is used for rotating and cutting the fluid-filled crab stick body 4 .

[0057] It should be noted that, in the present application, the cutting blade 6 includes three core components: a scabbard part, a blade part and a mounting part. The blade part is integrated into the internal cavity of the scabbard part in an embedded structure. The two form a coaxial assembly relationship through a precision cutting process and are installed together outside the mounting part. It is worth noting that the blade part in the present application is only popped out in the form of mechanical linkage before cutting the fluid-sandwich crab stick body 4. The internal surface of the scabbard part is maintained at a low temperature field of -5°C to 0°C through an integrated semiconductor cooling module, while the blade part is maintained at a constant temperature of 120°C±5°C through a resistance heating element. When the cutting operation is carried out, the high temperature on the surface of the blade part can instantly melt the protein fiber structure of the fluid-sandwich crab stick body 4, and at the same time, the low temperature field of the scabbard part enables the internal sandwich fluid to complete the solidification plasticity. The dual effects ensure that the cross-section of the fluid-sandwich crab stick body 4 forms a flat cross-section and realizes the microcapsule encapsulation of the internal fluid.

[0058] It should be added that the mounting part of the present application adopts a modular assembly design, specifically including a ring box 601, which is cast from aluminum alloy. It should also be noted that the two ring boxes 601 configured in the present application are arranged in a mirror-symmetrical layout, and the contact surfaces of the two ring boxes 601 are permanently fixed using a vacuum diffusion welding process, and the non-contact surfaces are respectively provided with a waterproof power supply interface that meets the IP68 standard, and a conductive cover 605 is installed at this interface.

[0059] It is worth noting that the mechanical linkage set in the inner cavity of the ring box 601 for installing the blade piece is to realize the trigger sleeve 505 with the help of external connectors to fix the position in the ring box 601. A raised contact ball is fixed on the outside of the trigger sleeve 505. During the rotation of the ring box 601 for installing the blade piece, the bottom of the blade piece pops out from the scabbard piece by contacting with the contact ball.

[0060] It should be noted that, in this application, the external connection includes: the cover 7 and the transmission assembly 5, refer to Figure 7 It can be seen that the cover body 7 is specifically in the form of a heat dissipation cover 701, which is used to dissipate heat from the cutting blade body 6.

[0061] The cutting blade 6 is assembled outside the cover 7, and a transmission assembly 5 is inserted inside. The transmission assembly 5 is used to transmit driving energy and limit and fix the trigger sleeve 505. The driving energy includes rotational energy and electrical energy.

[0062] It should be added that in the present application, the transmission component 5 is installed outside the crab stick conveyor 2 through the assembly component 3. When the fluid-stuffed crab stick body 4 carried on the surface of the crab stick conveyor 2 is continuously conveyed, the assembly component 3 transmits the driving energy through the transmission component 5, driving the cutting blade 6 to rotate along the periphery of the cover body 7, thereby completing the cutting and separation operation of the fluid-stuffed crab stick body 4.

[0063] It should be further explained that in the present application, the crab stick conveyor 2 is a transmission device in the prior art, and its core components include: a driving motor 201, a belt conveyor 202, a limiting rod 203, a belt transmission group 204, a gear matching group 205 and a mounting frame 206. It should be added that a control panel 1 is installed on the outside of the belt conveyor 202, and the control panel 1 is used to control the operation of the driving motor 201, the servo motor 305 and the functional seat 608.

[0064] Specifically, the driving motor 201 is fixed to the side wall of the frame by a flange connection, and its output shaft is connected to the main driving roller shaft end of the belt conveyor 202 through an elastic coupling, providing a basic power source for the whole machine. The belt conveyor 202 adopts a food-grade polyurethane synchronous belt structure with anti-slip convex patterns on the surface, which effectively improves the transportation stability of crab stick products. It is worth noting that the belt drive group 204 is installed in parallel on the right transmission end of the belt conveyor 202 through a processed aluminum alloy bracket. Its driving wheel forms a transmission with the side transmission shaft of the belt conveyor 202, thereby obtaining the rotational energy of the driving motor 201. Figure 1 and Figure 2 In the illustrated structure, the driven pulley end of the belt drive assembly 204 is sleeved onto the outer periphery of a stopper rod 203, located in the middle section of the outer side of the belt conveyor 202. Stopper rod 203 is made of stainless steel and features axial adjustment threads, ensuring belt tension and enabling fine-tuning of the transmission path. This unique design allows the belt drive assembly 204 to synchronously drive the gear assembly 205, which is rigidly connected to its internal double-row pulleys, to rotate. It is worth noting that the distal extension of stopper rod 203 is fitted with a mounting bracket 206, the main drive gear of gear assembly 205 nested within its shaft sleeve. A pressing roller, hard-anodized, is secured to the outer edge of the main drive gear via an interference fit. Driven by gear assembly 205, the continuous and uniform pressing of the pressed crab fillets is achieved.

[0065] It should be further emphasized that, since the crab stick conveyor 2 is a specific existing device, in this application, the detailed structure of the crab stick conveyor 2 is not further illustrated in the drawings.

[0066] It should also be added that, in the present application, the structure of the collar box 601 varies depending on the functional areas where the blade part and the scabbard part are installed.

[0067] Specifically, the outer surface of the ring box 601 for installing the blade piece is interspersed with an insertion rod 611 for contacting the contact ball and serving as the bottom of the blade piece through the opening 606. The insertion rod 611 is made of high-strength alloy steel and is precision-machined. The outer surface is installed with a return spring 612 integrated outside the ring box 601 by an interference fit. The return spring 612 is made of 60Si2Mn spring steel with a wire diameter of 1.2mm and a compression stroke of 8mm. The other end of the insertion rod 611 is connected to a connecting folding rod 610 through a precision hinge structure. The folded end of the connecting folding rod 610 is rigidly connected to the surface of the blade piece through a laser welding process, and its unfolding angle can be fine-tuned through a matching limit groove.

[0068] In addition, it should be noted that, in the present application, the outer surface of the collar box 601 for mounting the scabbard member is directly fixed to the bottom end of the scabbard member.

[0069] As a preferred embodiment, an electrical connection is established between the energy supply component and the transmission assembly 5. In order to adapt to the installation requirements of the blade and the scabbard, the structure of the energy supply component presents differentiated characteristics. When adapted to the blade, the composition structure of the energy supply component includes:

[0070] The functional seat 608 is internally provided with a rod-shaped interface adapted to the insertion rod 611. The structure of the rod-shaped interface distinguishes the characteristic quantities of the adaptive energy supply components of the scabbard part and the blade part, wherein the characteristic quantities specifically represent the basis for the distinction.

[0071] In addition, in this embodiment, the functional seat 608 forms a sliding fit with the external slide rail 702 of the cover body 7 through the slide groove 607 set on one side of the bottom, and the other side of the bottom of the functional seat 608 is rigidly connected to the ring box 601 through the conductive arm 602. The surface of the ring box 601 is integrated with a conductive cover 605 that forms a conductive loop with the conductive arm 602. There is an electrical connection between the conductive cover 605 and the transmission component 5, which ensures the electrical continuity of the entire system.

[0072] As a preferred embodiment, refer to Figures 7 to 11 It can be seen that in this embodiment, the scabbard component includes:

[0073] The scabbard 603 is integrally cast from a high-temperature alloy material. The outer side of the scabbard opening is designed with a sharp edge, and the inner side of the scabbard opening is paved with a thick silicon nitride ceramic insulation layer. The insulation layer is bonded to the substrate through a vacuum diffusion welding process to isolate the temperature exchange between the scabbard 603 and the blade 609. An arc-shaped notch 604 is provided at the central axis position on one side of the surface of the scabbard 603, which is bent toward the back along the scabbard opening. The arc-shaped notch 604 forms an interference fit with the cylindrical rod body connecting the folding rod 610.

[0074] The blade parts include:

[0075] Blade 609 is a double-edged tungsten steel blade, which is slidably connected to the scabbard 603 via a dovetail groove structure. The edge of blade 609 is precision-ground to maintain a 0.02mm level of fit with the scabbard opening. The back edge of blade 609 is electro-spark machined to form a T-shaped contact frame. The surface of the contact frame is provided with three groups of M3 threaded mounting holes, which are rigidly fixed to the bent portion of the connecting folding rod 610 by high-strength bolts.

[0076] As a preferred embodiment, in this embodiment, the transmission component 5 includes: a main transmission shaft 503 and a secondary transmission shaft 504, which are respectively inserted into the interior of the two ring boxes 601, wherein the secondary transmission shaft 504 is installed in the ring box 601 on which the blade piece is installed, and one end of the secondary transmission shaft 504 is hinged to one end of the main transmission shaft 503, and the outer periphery of one end of the secondary transmission shaft 504 is fixed to the inner wall of one end of the trigger sleeve 505, and the other end of the trigger sleeve 505 is not in contact with the inner wall of the ring box 601 on which the blade piece is installed, the surface of the contact end of the main transmission shaft 503 and the secondary transmission shaft 504 is fixed to the inner wall of the ring mouth of the ring box 601 on which the scabbard piece is installed, and the other end of the main transmission shaft 503 and the other end of the secondary transmission shaft 504 are jointly fixedly installed on the two ends of the inner wall of the assembly component 3.

[0077] It should be noted that in this embodiment, the transmission assembly 5 realizes the coordinated control of the blade part and the scabbard part through a dual-axis linkage structure, wherein the main transmission shaft 503 serves as the power input shaft, is driven to rotate by the servo motor 305, and acts on the secondary transmission shaft 504. The main transmission shaft 503 drives the ring box 601 on which the scabbard part is installed and the ring box 601 on which the blade part is installed to rotate, thereby realizing the cutting action of the blade 609. At the same time, since one end of the trigger sleeve 505 is fixed to the secondary transmission shaft 504, and the other end does not contact the inner wall of the ring box 601 on which the blade part is installed, such a design ensures that the position of the trigger sleeve 505 is uniquely defined, so that under the coordinated action of the main transmission shaft 503 and the secondary transmission shaft 504, the blade 609 can pop out of the scabbard 603 according to the position of the trigger sleeve 505, thereby ensuring the accuracy and stability of the cutting.

[0078] It should be further explained that in the present application, the outer surface of the main transmission shaft 503 and the secondary transmission shaft 504 are both covered with a conductive tube 502, one end of the conductive tube 502 is fixed to the inner wall of the assembly component 3, the outer surface of the conductive tube 502 is covered with an insulating cover 501, and the conductive tube 502 is placed at the position of the cover body 7 and an energy supply seat 506 is installed, and a rigid connecting conductive bundle is installed between the energy supply seat 506 and the conductive cover 605.

[0079] It should be noted that, in the present application, power is supplied to the energy supply base 506 through the conductive tube 502 , so that the energy supply base 506 provides the conductive cover 605 with electrical energy through the conductive beam.

[0080] As a preferred embodiment, in this embodiment, the assembly component 3 includes:

[0081] The connecting frame 301 is fixed on one end of the outer side of the crab stick conveyor 2. One side of the top of the inner wall of the connecting frame 301 is fixedly connected to the secondary transmission shaft 504. A servo motor 305 is installed on the other side of the top of the inner wall of the connecting frame 301. The shaft of the servo motor 305 passes through the connecting frame 301 and is fixed to one end of the main transmission shaft 503. A splash-proof arc plate 303 for covering the outside of the crab stick conveyor 2 is laid and fixed on the surface of the connecting frame 301 near the position of the crab stick conveyor 2. A retention gap 304 is left between the two splash-proof arc plates 303 for the cutting blade 6 to rotate. The bottom end of the inside of the connecting frame 301 is fixed with a reinforcing arm 302 that is fitted on the bottom of one end of the outer side of the crab stick conveyor 2.

[0082] It should be noted that in this embodiment, the main drive shaft 503 is driven by the servo motor 305 to obtain rotational power, thereby driving the entire cutting blade 6 to rotate and cut. The provision of the reinforcement arm 302 enhances the stability between the connecting frame 301 and the crab stick conveyor 2, ensuring the stability of the device during the cutting process. The design of the splash arc plate 303 effectively prevents the splash of crab stick juice or debris during cutting, maintaining a clean working environment. The retention gap 304 ensures that the cutting blade 6 has sufficient space for rotational cutting and avoids interference with the movement of the cutting blade 6 by the splash arc plate 303, ensuring smooth and accurate cutting.

[0083] Secondly, in order to improve the disclosed fluid-stuffed crab stick cutting device, a method for using the fluid-stuffed crab stick cutting device is also proposed.

[0084] It is worth noting that a method for using a fluid-stuffed crab stick cutting device includes: steps S100 to S600.

[0085] Step S100: Start the servo motor 305 to drive the belt conveyor 202 to operate, and transport the preformed fluid-filled crab stick body 4 to the cutting station. At this time, the gear matching group 205 synchronously drives the pressing roller to radially compress the crab stick.

[0086] Step S200: When the human eye detects that the crab sticks are placed on the surface of the belt conveyor 202, the control panel 1 transmits electric energy to the power supply seat 506 through the conductive tube 502, and supplies energy to the blade 609 and the functional seat 608 outside the scabbard 603 through the conductive beam, so that the blade 609 and the scabbard 603 reach the working temperature in advance, wherein the working temperatures of the blade 609 and the scabbard 603 are 120℃±5℃ and -5℃ to 0℃ respectively.

[0087] Step S300: When the fluid-filled crab stick body 4 moves to the cutting station, the servo motor 305 drives the cutting blade 6 to rotate through the main transmission shaft 503. During the rotation of the blade, every time the trigger sleeve 505 rotates to the phase angle where it collides with the contact ball, the secondary transmission shaft 504 generates axial displacement. The mechanical linkage of the axial displacement drives the connecting folding rod 610 to unfold through the inserted rod 611, so that the blade 609 is guided out of the scabbard 603 under the action of the connecting folding rod 610 and the arc-shaped notch 604, and forms an effective cutting stroke.

[0088] Step S400: When the blade 609 penetrates the crab stick body, the high-temperature edge causes the surimi protein in the contact area to form a thick dense solidified layer. At the same time, the semiconductor cooling module on the inner wall of the scabbard 603 maintains a low temperature field of -3°C, which increases the viscosity of the sandwich fluid on the surface after cutting, realizing cross-section microcapsule encapsulation.

[0089] Step S500: After the cutting is completed, the return spring 612 drives the insertion rod 611 to reset. At this time, the connecting folding rod 610 drives the blade 609 to be completely retracted into the scabbard 603 to avoid interference with the crab sticks subsequently transported.

[0090] Step S600: After the batch cutting is completed, the power supply of the servo motor 305 is first cut off, and the cutter body is cleaned and maintained after it completely stops rotating. By spraying 82°C sterile pure water into the ring box 601, the contact part is pasteurized using the residual heat of the cutter body.

[0091] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the accompanying embodiments and their equivalents.
