Abstract

Through the cooperation of a clamping mechanism and other structures, during the clamping process, two elastic elements push an extension plate and a positioning plate towards the sides of the fish.

The spiked plate immediately moves and its side metal spikes pierce the tail, thus achieving fixation. By changing the magnetic attraction distance, the position of the spiked plate is altered, significantly enhancing the versatility and adaptability of the clamp, improving the clamping effect on fish of different sizes, and reducing the time and effort required for workers to change or adjust the clamped workpiece. The two sets of metal spikes are staggered and can directly pierce the tail muscle of the fish. Combined with the magnetic attraction force, the double locking effectively improves the clamping effect and prevents the fish from escaping.

TECHNICAL FIELD

[0001] The application belongs to the technical field of fish processing, and particularly relates to a fish scale removing and abdominal cavity opening device for fish processing. BACKGROUND

[0002] The fish scale removing and abdominal cavity opening device is a key equipment in fish primary processing, and its function is to remove scales, open abdominal cavity and remove internal organs of fish, wherein the positioning and supporting of the fish body is a prerequisite for ensuring the processing quality. In the prior art, the positioning and supporting of the fish body mainly adopts an up-down clamping type positioning, that is, a V-shaped channel or a lower profiling cone is arranged below the fish body as a bottom support, an upper profiling cone or a pressing plate is correspondingly arranged above the fish body, the fish body is clamped and fixed by a downward pressing force applied by a spring, and gear transmission structures are added before and after the scale removing and abdominal cavity opening structure, the structure comprises two groups of gears, each group of gears is equidistantly installed on an axle and connected by an elastic member, so as to adapt to fish of various sizes.

[0003] However, the above positioning and supporting structure is difficult to adapt to fish of different sizes. In the up-down clamping type positioning, the pressing force is usually provided by a spring and is a constant value, the cross-sectional size of different fish species and the same fish from head to tail is significantly different, the constant pressing force cannot be adaptively adjusted according to the fish body profile, which causes the fish body to be damaged due to the clamping of the thicker part of the fish body being too tight, the fish body to be offset or slipped due to the clamping of the thinner part of the fish body being insufficient, and the clamping distance to be manually adjusted when fish of different sizes are switched for processing, which leads to unreliable clamping of some fish species and easy falling off of the fish body. The above problems make it difficult for the existing device to provide stable and reliable positioning and supporting for fish of various sizes, which affects the processing quality of scale removing and abdominal cavity opening. SUMMARY

[0004] To solve the problems in the background art, the application provides a fish scale removing and abdominal cavity opening device for fish processing, which solves the problems of fixed position of the existing clamp, inability to adapt to the sizes of various fish, and possible damage and falling off of the fish in the clamp.

[0005] To achieve the above purpose, the application provides the following technical scheme: a fish scale removing and abdominal cavity opening device for fish processing, comprising a supporting mechanism, a platform is installed at the top of the supporting mechanism, a variable posture mechanism is installed at both ends of the platform, a clamping mechanism one is installed between the two variable posture mechanisms, and a clamping mechanism two for fixing the head part of the fish is installed on one of the variable posture mechanisms. The clamping mechanism one comprises two supports symmetrically designed above and below and fixed between the two variable posture mechanisms, two symmetrically distributed clamps are jointly installed on the two supports, and a notch for the abdominal cavity opening knife to enter is arranged at the bottom of the lower support. One of the clamps includes a sliding frame that is slidably engaged with one side of two supports. A support plate is connected to the middle of the sliding frame via a spring telescopic rod. A roller is rotatably mounted on the inner side of the support plate. A positioning plate is hinged to the side of the support plate via an extension plate. The two sides of the extension plate are respectively connected to the support plate and the positioning plate via two elastic elements. The positioning plate 1 is slidably engaged with the spike plate in the middle, and the positioning plate 1 is connected to the spike plate through the elastic element 2. The two spiked plates are provided with metal spikes on their opposite sides, and the two sets of metal spikes are staggered. The two spiked plates are also provided with a set of strong magnets that can attract each other on their opposite sides.

[0006] Preferably, the roller is rolled with an anti-slip mesh groove, and the two elastic elements can respectively push the extension plate and the positioning plate to fold inward.

[0007] Preferably, the elastic element pulls the spike plate outward, and the two supports are symmetrically designed with a recessed center.

[0008] Preferably, one of the posture-changing mechanisms includes a support plate that is slidably engaged with the top of the platform, a posture-changing plate that is rotatably engaged with the support plate, a set of positioning grooves arranged in a circumferential array on the outer edge of the posture-changing plate, a locking pin that can be inserted into the positioning grooves that is vertically engaged with the outer side of the support plate, and a torsion plate that is provided on the outer side of the posture-changing plate.

[0009] Preferably, the bracket is installed between two attitude change plates, and a set of circumferentially arrayed placement plates are installed on the inner edge of the attitude change plates. The edge of the placement plates is flat, and a positioning groove for the sliding frame to enter is provided on the platform.

[0010] Preferably, the clamping mechanism two includes a metal pin fixed to the inner side of the posture changing plate, and the two ends of the inner side of the posture changing plate are respectively hinged to the positioning plate two by the spring telescopic plate two, and the positioning plate two and the spring telescopic plate two are connected by the elastic element three.

[0011] Preferably, the second clamping mechanism further includes two sets of locking slots symmetrically opened on the metal pin, each set of locking slots is designed to be equidistant, the second positioning plate can penetrate the gills and be engaged with the locking slots, and the metal pin can be inserted into the fish mouth.

[0012] Preferably, the support mechanism includes a base, the top of which is provided with an arc-shaped support platform. A semi-circular adjustment platform is slidably engaged inside the support platform. The platform is fixedly mounted on the top of the adjustment platform. Two internal gears are symmetrically installed on the inner wall of the adjustment platform. Two gears are rotatably mounted on the middle of the support platform extending to the inner side of the adjustment platform. The gears mesh with the internal gears. A bearing plate is hinged to the inner side of the support platform through two spring telescopic plates. Two toothed plates that mesh with the gears are installed at the bottom of the bearing plate.

[0013] Preferably, the bottom of the bearing plate is engaged with the inner side of the support platform by two partitions, and the spring telescopic plate always pulls the bearing plate down and engages the toothed plate with the gear in the initial state.

[0014] Preferably, the support mechanism further includes two limiting grooves symmetrically opened on the bearing plate, and two positioning rods are symmetrically fixed at both ends of the inner wall of the support platform, the positioning rods fitting into the limiting grooves.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordinated structure of a clamping mechanism, allows two elastic elements to push the extension plate and positioning plate towards the sides of the fish during clamping. When the positioning plate is at the fish's tail, the distance between the two sets of strong magnets decreases to the point where they can attract each other. The spiked plate immediately moves and its side metal spikes pierce the fish's tail, thus achieving fixation. By changing the magnetic attraction distance, the position of the spiked plate is altered, significantly enhancing the versatility and adaptability of the clamp, improving the clamping effect on fish of different sizes, and reducing the time and effort required for workers to change or adjust the clamped workpiece. The two sets of metal spikes are staggered and can directly pierce the fish's tail muscle. Combined with the magnetic attraction, the double locking effectively improves the clamping effect and prevents the fish from escaping.

[0016] This invention, through the cooperation of a clamping mechanism and other structures, allows a metal pin to enter the fish's mouth. Then, pulling the positioning plate two causes the spring-loaded telescopic plate two to extend, extending the positioning plate two from the gills into the fish's mouth. The spring-loaded telescopic plate two automatically retracts, and the elastic element three pushes the positioning plate two inwards, thus locking it in the locking groove, forming an internal self-locking mechanism. Compared to existing clamping mechanisms that directly fix the fish head from the outside, this effectively reduces situations where the fish head clamp cannot fit or slips due to mucus. It also further improves the applicability of the clamping mechanism and avoids the clamps pressing on the surface of the fish head, which can easily cause bruising or deformation, affecting the appearance. The internal fixation of the positioning plate two does not contact the outer surface of the fish; the clamping force acts on the inside of the fish's mouth and gill cavity, without affecting the commercial appearance of the fish.

[0017] This invention, through the cooperation of supporting mechanisms and other structures, allows the support plate to move upwards, and the toothed plate to disengage from the gears, changing the position of the platform. This allows the platform to be adjusted to accommodate different cutting tools or descaling equipment in different mechanisms. After moving upwards, the support plate is folded over, causing the positioning rod to engage in the limiting groove. This further reduces the cost and effort of manual labor, and also facilitates subsequent position adjustments. If manual gutting or descaling is required, adjusting the platform to an inclined position makes it easier for workers to apply force during scalening and gutting. It also adapts to the operating habits of different workers, thereby improving work efficiency. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 8 As shown, the present invention provides a fish scale-removing and gutting device for fish processing, including a support mechanism 1, a platform 2 installed on the top of the support mechanism 1, a posture-changing mechanism 3 installed at each end of the platform 2, a clamping mechanism 4 installed between the two posture-changing mechanisms 3, and a clamping mechanism 5 for fixing the fish head part installed on one of the posture-changing mechanisms 3. The clamping mechanism 4 includes two supports 41 fixed between two posture changing mechanisms 3 and designed symmetrically. Two symmetrically distributed clamps 42 are installed on the two supports 41. The bottom of the lower support 41 is provided with a slot for the laparotomy knife to enter. One of the clamps 42 includes a sliding frame 421 that is slidably engaged with one side of two supports 41. A support plate 423 is connected to the middle of the sliding frame 421 via a spring telescopic rod 422. A roller 424 is rotatably mounted on the inner side of the support plate 423. A positioning plate 427 is hinged to the side of the support plate 423 via an extension plate 426. The two sides of the extension plate 426 are respectively connected to the support plate 423 and the positioning plate 427 via two elastic elements 425. The roller 424 has anti-slip mesh grooves rolled on it, and the two elastic elements 425 can push the extension plate 426 and the positioning plate 427 to fold inward respectively.

[0022] The elastic element 428 pulls the spike plate 429 to move outward. The two supports 41 are symmetrically designed and have a concave design in the middle.

[0023] The positioning plate 427 is slidably engaged with the spike plate 429 in the middle, and the positioning plate 427 is connected to the spike plate 429 through the elastic element 428. The two barbed plates 429 are provided with metal spikes on their opposite sides, and the two sets of metal spikes are staggered. The two barbed plates 429 are also provided with a set of strong magnets 420 that can attract each other on their opposite sides.

[0024] Using the above scheme: the fish is first placed between two supports 41 and the head of the fish is fixed by the clamping mechanism 2 5. Then, the sliding frame 421 is used as the handle of the moving clamp 42. During this period, the spring telescopic rod 422 pushes the roller 424 from the head of the fish to its tail through the support plate 423, thereby forcing the fish to change from a curved state to a straight state. During the rolling process, the two elastic elements 425 push the extension plate 426 and the positioning plate 427 to fit against the sides of the fish. When the roller 424 moves to the tail fin of the fish, the positioning plate 427 is simultaneously located at the tail of the fish, and the distance between the two sets of strong magnets 420 is reduced to a state where they can attract each other. Therefore, the barb plate 429 in the positioning plate 427 will move immediately and pierce the tail of the fish with its side metal spikes, thereby achieving the purpose of fixing. By changing the position of the barb plate 429 through the change of the magnetic attraction distance, the versatility and adaptability of the gripper 42 are greatly improved. It is important to note that the movement of the barb plate 429 is based on magnetic attraction. When the positioning plate 427 is located at the fish tail, the two sets of strong magnets 420 are closest, so they can directly attract each other, thereby guiding the barb plate 429 to fix the fish tail. This further improves the clamping effect of the device on fish of different sizes, while also enhancing the applicability of the device. It reduces the time and effort required for workers to change or adjust the clamped workpieces, and saves the factory money by purchasing additional clamps. The two sets of metal spikes are designed in an interlaced pattern and can directly pierce the fish's tail muscle. Combined with the magnetic attraction, the double locking can more effectively improve the clamping effect and prevent the fish from breaking free.

[0025] Depend on Figure 7As can be seen, the posture-changing mechanism 3, clamping mechanism 1 4, and clamping mechanism 2 5 can all be independent of platform 2. Therefore, after the fish is positioned, the fish and clamps can be directly pushed into the descaling and gutting mechanism. During this process, the fish first passes through the descaling spring, which is made of a rigid spring with externally welded descaling blades. During the rotation of the descaling spring, the scales are removed. Then, the fish is moved by two sets of gears. Since the head and tail of the fish are fixed by clamping mechanism 2 5 and clamping mechanism 1 4 respectively, the whole is in a straight line state, which avoids the fish from wagging its tail and becoming unstable, which would cause the gears to be unable to move the fish well and the descaling spring to be unable to fully act on the fish. Because the lower support 41 has a slot for the ventriloquist knife to enter, the fish enters in a straight line during the final ventriloquist procedure. This avoids the fish moving around due to stress after scaling, which could result in an incomplete ventriloquist line and prevent the fish's belly from being completely opened.

[0026] like Figures 1-10 As shown, one of the posture changing mechanisms 3 includes a support plate 31 that is slidably engaged with the top of the platform 2. A posture changing plate 32 is rotatably engaged on the support plate 31. A set of positioning grooves 34 are arranged in a circumferential array on the outer edge of the posture changing plate 32. A locking pin 36 that can be inserted into the positioning groove 34 is vertically slidably engaged on the outer side of the support plate 31. A torsion plate 37 is provided on the outer side of the posture changing plate 32.

[0027] The bracket 41 is installed between two attitude change plates 32. A set of circumferential array-designed placement plates 33 are installed on the inner edge of the attitude change plate 32. The edge of the placement plate 33 is flat. The platform 2 is provided with a positioning groove 21 for the sliding frame 421 to enter.

[0028] Using the above scheme: when the fish needs to be manually scaled and its position needs to be changed to facilitate subsequent scaling and gutting, the upper sliding lock pin 36 can be disengaged from the positioning groove 2 34. The posture changing plate 32 can be rotated through the torsion plate 37, so that the fish changes from vertical to horizontal and is placed on the top of the platform 2. During this process, the sliding frame 421 can pass through the positioning groove 1 21, so that the fish fits the platform 2 better and can further fix the position of the clamp 42, making the clamp 42 more effective in clamping the fish. It should also be noted that when the fish lies on its side on platform 2, platform 2 can provide reverse support for the fish, thereby reducing the probability of the fish bending or falling out of the gripper 42 when scaling is performed. In addition, the fish belly is directly exposed from the groove at the bottom of the bracket 41, which makes it easier for subsequent gutting work.

[0029] like Figures 1-10As shown, the clamping mechanism 2 5 includes a metal pin 51 fixed to the inner side of the posture plate 32. The two ends of the inner side of the posture plate 32 are respectively hinged to the positioning plate 2 54 by the spring telescopic plate 2 52. The positioning plate 2 54 and the spring telescopic plate 2 52 are connected by the elastic element 3 53.

[0030] The clamping mechanism 2 5 also includes two sets of locking grooves 511 symmetrically opened on the metal pin 51. Each set of locking grooves 511 is designed to be equidistant. The positioning plate 2 54 can pass through the gills and be snapped into the locking grooves 511. The metal pin 51 can be inserted into the fish mouth.

[0031] Using the above method: After the fish is positioned between the two supports 41, move the fish so that the metal pin 51 enters the fish's mouth. Then pull the positioning plate 2 54, and the spring telescopic plate 2 52 extends, extending the positioning plate 2 54 from the gills into the fish's mouth. When the operator relaxes, the spring telescopic plate 2 52 automatically retracts, and the elastic element 3 53 pushes the positioning plate 2 54 to fold inward, that is, the positioning plate 2 54 is locked in the locking groove 511. After the internal self-locking mechanism is formed, compared with the existing clamping mechanism, the technical solution of directly clamping the fish head reduces the excessive mucus secreted by the fish, which may cause it to break free of the clamp during the struggle. Furthermore, the positioning plate 2 54 is directly inserted into the fish gills and forms a locking effect with the locking groove 511, which can effectively reduce the situation where the fish head clamp cannot be adapted or slips due to mucus, and further improve the applicability of clamping. The existing external clamps press on the surface of the fish head, which can easily cause bruising or deformation, affecting the appearance. Positioning plate 254 is fixed internally and does not contact the outer surface of the fish. The clamping force acts on the inside of the fish mouth and gill cavity, which does not affect the commercial appearance of the fish. It should be noted that the clamping mechanism 25 only fixes the fish head, so it will not affect the scaling and gutting of the fish body.

[0032] like Figures 1-10 The support mechanism 1 shown includes a base 11, with an arc-shaped support platform 12 on the top of the base 11. A semi-circular adjustment platform 13 is slidably engaged inside the support platform 12. A platform 2 is fixedly mounted on the top of the adjustment platform 13. Two internal gears 131 are symmetrically installed on the inner wall of the adjustment platform 13. The middle part of the support platform 12 extends to the inner side of the adjustment platform 13 and is rotatably mounted with two gears 14. The gears 14 mesh with the internal gears 131. A bearing plate 16 is hinged to the inner side of the support platform 12 through two spring telescopic plates 15. Two toothed plates 17 that mesh with the gears 14 are installed at the bottom of the bearing plate 16.

[0033] The bottom of the support plate 16 is snapped into the inner side of the support platform 12 by two partitions 18. In the initial state, the spring telescopic plate 15 always pulls the support plate 16 down and makes the toothed plate 17 mesh with the gear 14.

[0034] The support mechanism 1 also includes two limiting grooves 161 symmetrically opened on the bearing plate 16, and two positioning rods 19 are symmetrically fixed at both ends of the inner wall of the support platform 12, and the positioning rods 19 fit into the limiting grooves 161.

[0035] Using the above scheme: When manually scaling and gutting the fish, the support plate 16 is moved upward so that the toothed plate 17 is no longer engaged with the gear 14. When the operator manually changes the position of the platform 2 to adapt the fish to the knives or scaling equipment in different mechanisms, the platform 2, together with the adjustment platform 13 at its bottom and the internal gear 131, rotates at the same time. Since the gear 14 is not restricted by the toothed plate 17, the gear 14 can also rotate freely, and the position of the platform 2 can be adjusted. After moving upwards, the bearing plate 16 is folded over, which allows the positioning rod 19 to be locked in the limiting groove 161, thereby freeing the workers from holding the bearing plate 16 and enabling them to adjust the position of the platform 2 with both hands, further reducing the cost and effort of manual labor, and making it easier to adjust the position later. It should also be noted that if manual evisceration or descaling is performed, adjusting the position of platform 2 to an inclined state can make it easier for workers to descale and exert force during evisceration, and can also adapt to the operating habits of different workers, thereby increasing work efficiency.

[0036] Working principle and usage process of this invention: The fish is placed between the two supports 41. The fish is moved so that the metal pin 51 enters the fish's mouth. Then, the positioning plate 2 54 is pulled from the gills into the fish's mouth. When the operator relaxes, the spring telescopic plate 2 52 automatically retracts, and the elastic element 3 53 pushes the positioning plate 2 54 to fold inward, that is, the positioning plate 2 54 is locked in the locking groove 511. Then, the clamp 42 is moved, and the spring telescopic rod 422 pushes the roller 424 from the head of the fish to its tail through the support plate 423, forcing the fish to change from a curved state to a straight state. During the rolling process, the elastic element 425 pushes the extension plate 426 and the positioning plate 427 to fit against the fish. When the roller 424 moves to the tail fin of the fish, the positioning plate 427 is simultaneously located at the tail of the fish. The distance between the two sets of strong magnets 420 is reduced to a state where they can attract each other. The barb plate 429 moves immediately and pierces the tail of the fish with metal spikes, thereby achieving the purpose of fixing. Then the diaphragm removal or descaling can begin.
