Description

Technical Field

[0001] This invention relates to the field of squid processing technology, and more particularly to a squid processing line. Background Technology

[0002] In the squid processing industry, to obtain uniformly sized tentacles or complete squid slices, the squid typically requires meticulous slitting. Because the squid's body is rigid and has a regular outline, while the tentacles are soft and multi-branched, their physical properties differ significantly. Therefore, during automated cutting, it is essential to ensure that the squid enters the cutting station in a uniform, standardized posture. For example, transverse slitting is required for the tentacles, while longitudinal slitting is necessary for the body. If the squid enters the cutting machine with inconsistent orientation, it will lead to cutting position deviations, severely impacting yield and product quality.

[0003] However, existing squid processing lines lack mechanisms to organize the squid's posture. During transport, the scattered squid material is randomly distributed, with some heads and tails facing forward and others tentacles facing forward, making it difficult for the slitting machine to precisely position and cut different parts. Furthermore, to solve this problem, current methods rely heavily on manual pre-arranging, which is labor-intensive, inefficient, and difficult to control in terms of hygiene, severely hindering the mass production and automation of squid processing. Summary of the Invention

[0004] In view of this, the present invention proposes a squid processing line that can standardize the posture of squid and improve the efficiency of differentiated batch processing of squid.

[0005] The technical solution of this invention is implemented as follows: This invention provides a squid processing line, including a hoist, a chute, a slitting machine, and a straightening mechanism. The straightening mechanism includes a slide, a stop bar, and two springs. The hoist, the chute, and the slitting machine are arranged sequentially. The chute is inclined, and the installation height of the end of the chute near the hoist is higher than the installation height of the other end of the chute. The slide is slidably mounted on the chute. The stop bar is fixedly mounted on the slide, with one end of the stop bar extending outwards. The squid enters the sliding groove and is slidably connected to it; both springs are mounted on the sliding groove; in its natural state, the springs abut against both sides of the slide, causing the stop bar to slide to the middle position within the sliding groove; if the squid slides into the sliding groove with its body facing forward, the squid drives the stop bar to slide to the side of the sliding groove; if the squid slides into the sliding groove with its tentacles facing forward, the base of the squid's tentacles engages with the stop bar, causing the tentacles of the squid that slide onto the sliding machine to all face the sliding groove.

[0006] Based on the above technical solution, preferably, there are two slides, which abut against each other and are supported between the two springs; there are two stop bars, which are spaced apart and fixedly mounted on the two slides respectively.

[0007] Based on the above technical solutions, preferably, the stop bar includes a rod body and a baffle plate; the rod body is fixedly mounted on the slide; the baffle plate is fixedly mounted at the end of the rod body away from the slide, and the outer diameter of the baffle plate is larger than the outer diameter of the rod body.

[0008] Based on the above technical solutions, preferably, the side of the baffle closest to the rod is conical, and a pointed part is provided on the upper part of the periphery of the rod.

[0009] Based on the above technical solutions, preferably, the sliding groove is provided with sliding holes, the sliding holes are arranged along the width direction of the sliding groove, and the stop bar is slidably disposed in the sliding holes.

[0010] Based on the above technical solutions, preferably, it also includes a fish-pulling mechanism, which includes a rotating frame and a lever; the rotating frame is rotatably mounted on the sliding groove; the lever is fixedly mounted on the rotating frame; when the base of the squid's tentacles engages with the stop bar, the rotating frame drives the lever to extend into the sliding groove and pushes the squid to fall below the stop bar.

[0011] Based on the above technical solutions, preferably, the sliding groove is provided with two horizontal holes and a vertical hole. The two horizontal holes are parallel and spaced apart, and both are parallel to the width direction of the sliding groove. The vertical hole is perpendicular to the horizontal holes and is connected between the two horizontal holes. The lever is slidably disposed in the horizontal hole. The rotating frame is slidably disposed in the vertical hole.

[0012] Based on the above technical solutions, preferably, multiple levers are provided; the fish-pulling mechanism also includes multiple connecting rods, which are fixedly arranged between two adjacent levers and slidably arranged in the longitudinal hole.

[0013] Based on the above technical solutions, preferably, the lever includes a main rod, a stepped portion, and a filling portion; the main rod is fixedly mounted on the rotating frame; the stepped portion is integrally formed on the periphery of the main rod, and when the main rod slides into the lower transverse hole, the stepped portion extends into the sliding groove; the filling portion is integrally formed on the periphery of the main rod, and when the main rod slides into the upper transverse hole, a portion of the filling portion is flush with the inner wall of the sliding groove.

[0014] Based on the above technical solution, preferably, the sliding groove includes a U-shaped frame, an adjusting plate, multiple nuts, multiple screws, a first support plate, a second support plate, and a sliding shaft; the U-shaped frame is inclined and has a sliding hole inside; the adjusting plate is located inside the U-shaped frame; the nuts are rotatably mounted on the U-shaped frame; the screws are fixedly mounted on the adjusting plate, with one end extending out of the U-shaped frame and connected to the nuts via threaded engagement, and multiple screws correspond one-to-one with multiple nuts; the first support plate is fixedly mounted in the sliding hole at the end away from the nuts; the second support plate is fixedly mounted on the adjusting plate and slidably mounted in the sliding hole; the sliding shaft is fixedly mounted on the first support plate and slidably connected to the second support plate; the springs are sleeved on the sliding shaft, and the ends of the two springs away from the slide respectively abut against the first support plate and the second support plate.

[0015] The squid processing line of the present invention has the following advantages over the prior art: (1) By setting a straightening mechanism on the chute, the squid with the body and tentacles can pass through the straightening mechanism by taking advantage of the difference in physical characteristics between the squid body and tentacles, while squid with the body facing forward cannot pass through the straightening mechanism, thereby ensuring that the squid on the slitting machine have a uniform posture, so as to improve the efficiency of differentiated batch processing of squid.

[0016] (2) By setting up a fish-pulling mechanism and cooperating with the straightening mechanism, the squid with its tentacles facing forward can be converted into a body-facing position, thereby realizing the automated processing of squid and improving the processing efficiency of squid.

[0031] The technical solutions of this invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0032] The present invention discloses a squid processing line, comprising an elevator 1, a chute 2, a slitting machine 3, a straightening mechanism 4, and a squid-pulling mechanism 5, which can adjust the orientation of the squid's head and tail to achieve differentiated batch processing of the squid's body and tentacles.

[0033] Among them, the elevator 1 is preferably a bucket elevator, which is used to lift the scattered squid material from a low position to a high position one by one; the slitting machine 3 includes a conveyor belt and multiple cutters that can move in the vertical direction to achieve different cutting processes.

[0034] The sliding chute 2 has an internal cavity, slightly wider than the squid, to ensure smooth material passage while restricting the squid's orientation. For example... Figure 1 and Figure 2 As shown, the elevator 1, the chute 2, and the slitting machine 3 are arranged in sequence. The chute 2 is inclined, with its installation height near the elevator 1 being higher than that of the other end, using gravitational potential energy to drive the material downwards. After the squid is conveyed to the upper end of the chute 2 by the elevator 1, it is guided and limited by the aligning mechanism 4 and adjusted in posture by the fish-pulling mechanism 5 during its descent, ensuring that the squid arriving at the lower end of the chute 2 maintain a uniform orientation. This standardized posture arrangement creates favorable conditions for the precise operation of the slitting machine 3: transverse slitting can be performed on the tentacles to prepare uniform tentacles, while longitudinal slitting can be performed on the squid body to remove the internal organs and obtain complete squid slices, thus achieving fully automated and efficient processing.

[0035] In a preferred embodiment, the alignment mechanism 4 includes a slide 41, a stop bar 42, and two springs 43. The slide 41 is slidably disposed on the bottom side of the slide groove 2 along the width direction of the slide groove 2. The stop bar 42 is fixedly disposed on the slide 41, and one end of the stop bar 42 extends into the cavity of the slide groove 2 and is slidably connected to the slide groove 2. The two springs 43 are respectively disposed on both sides of the slide groove 2 and respectively abut against both sides of the slide 41. In a natural, unforced state, the elastic force of the two springs 43 balances the position of the slide 41 and the stop bar 42 in the center, that is, the stop bar 42 is located in the middle position of the cross-section of the slide groove 2.

[0036] The squid's body is relatively rigid and has a regular outline, while its tentacles are soft and arranged in multiple rows. When the squid slides down the slide chute 2 with its body facing forward, the squid can smoothly push the baffle 42 to slide to the side of the slide chute 2 due to the small elastic force of the spring 43, thus passing through the straightening mechanism 4 without obstruction and being directly conveyed to the slitting machine 3. When the squid slides down with its tentacles facing forward, the multiple soft tentacles are easily distributed on both sides of the baffle 42, thus forming a locking relationship with the baffle 42, thereby locking the baffle 42 in the center position and preventing the squid from continuing to descend. Subsequently, the fish-pushing mechanism 5 applies a pushing force to complete the controllable flipping of the squid around the baffle 42, changing the squid from a "tentacles facing forward" to a standard "body facing forward" posture, and moving it onto the conveyor belt of the slitting machine 3. As a result, all squid entering the slitting machine 3 have the same spatial orientation, that is, the tentacles face the sliding groove 2 side and the body faces the opposite side, providing a precise geometric reference for subsequent differentiated slitting, significantly improving cutting accuracy, yield and processing cycle stability.

[0037] Furthermore, such as Figures 3 to 7 As shown, both the slide 41 and the baffle 42 adopt a double-set symmetrical arrangement. The two slides 41 abut against each other along the width direction of the sliding groove 2 and are supported by the two springs 43. The two baffles 42 are parallel and spaced apart, and are fixedly mounted on the two slides 41 respectively. The setting of the two baffles 42 can not only avoid the baffles 42 from being deformed or worn due to the concentrated impact of the sharp part of the squid's front end, thus extending the service life of the device, but also reduce the risk of mechanical damage to the squid and ensure the quality of squid products. At the same time, the two baffles 42 form more limiting areas, making it easier for the multi-tentacle to form a locking relationship with the baffles 42.

[0038] like Figure 8 As shown, the stop bar 42 includes a bar body 421 and a baffle plate 422; one end of the bar body 421 is fixedly mounted on the slide 41; the baffle plate 422 is fixedly mounted on the end of the bar body 421 away from the slide 41; the outer diameter of the baffle plate 422 is larger than the outer diameter of the bar body 421, and the side of the baffle plate 422 near the bar body 421 is preferably conical, forming a conical guiding structure, which not only makes it easier for the squid tentacles to be inserted between the baffle plate 422 and the sliding groove 2, but also prevents the squid from directly detaching from the stop bar 42 during the flipping process; a pointed part 401 is provided on the upper part of the periphery of the bar body 421, which can make it easier for the bar body 421 to be inserted into the root of the squid tentacles, forming a snap-fit ​​relationship, further improving the limiting effect of the straightening mechanism 4 on the squid.

[0039] In addition, such as Figure 6As shown, the sliding groove 2 has a sliding hole 201 extending along its width, through which the rod 421 passes, thus guiding the rod 421 to slide. In its natural state, two springs 43 abut against the two slides 41 from both sides, so that the two slides 41 are in a balanced position of mutual contact, thereby driving the two stop rods 42 to be synchronously centered. That is, the two stop rods 42 are symmetrically distributed on both sides of the center line of the cross-section of the sliding groove 2, and maintain a reserved gap, forming a squid conveying posture identification mechanism.

[0040] When the squid enters the straightening mechanism 4 with its body facing forward, its front end makes surface contact with the stop bar 42. Through the squid's compression action, it pushes the two slides 41 to slide synchronously to both sides of the sliding groove 2, causing the two stop bars 42 to move outward along the sliding hole 201 to their extreme positions (e.g., Figure 7 As shown), the slide is instantly unobstructed, allowing the squid to pass through and be transported to the slitting machine 3 without hindrance; when the squid slides down with its tentacles facing forward, its multi-branched, flexible, and somewhat elastic tentacles naturally open under inertia, easily forming a locking relationship with the two stop levers 42, thereby locking the displacement of the slide 41. At this time, the two stop levers 42 maintain... Figure 6 The centered position shown forms a mechanical "posture interception barrier," effectively preventing squid with non-standard orientations from continuing to descend and avoiding squid entering the slitting machine 3 directly without being properly aligned. This fundamentally ensures the uniformity of positioning references and the consistency of processing quality in subsequent slitting processes.

[0041] In a preferred embodiment, the sliding groove 2 is provided with two parallel and spaced horizontal holes 202, and a vertical hole 203 connecting the two horizontal holes 202; wherein, the two horizontal holes 202 are parallel to the width direction of the sliding groove 2, and the vertical hole 203 is perpendicular to the horizontal holes 202, and the three together form an I-shaped through hole; this hole system not only provides a precise motion constraint path for the fish-pulling mechanism 5, but also realizes synchronous linkage and spatial coordination between various components through geometric coupling.

[0042] like Figure 9 and Figure 10 As shown, the fish-pulling mechanism 5 includes a rotating frame 51, a lever 52, and multiple connecting rods 53. The rotating frame 51 is rotatably mounted on the outside of the sliding groove 2 and slidably mounted in the longitudinal hole 203. The lever 52 is fixedly mounted on the rotating frame 51 and slidably mounted in the transverse hole 202. When the base of the squid's tentacles is engaged with the baffle 42 and temporarily blocked at the straightening mechanism 4, the rotating frame 51 rotates under external driving force, causing the lever 52 to extend into the cavity of the sliding groove 2 along the transverse hole 202, so as to push the squid to rotate controllably around the baffle 42, so that it changes from the "tentacles facing forward" posture to the standard conveying posture of "body facing forward", and finally falls into the area below the baffle 42 and enters the cutting machine 3 station.

[0043] Preferably, multiple levers 52 are configured, with one lever 52 located in one transverse hole 202 and another lever 52 located in another transverse hole 202, to prevent squid tentacles from accidentally probing into the holes and causing entanglement or damage. Simultaneously, a connecting rod 53 is fixedly provided between adjacent levers 52, and the connecting rod 53 is slidably disposed within the longitudinal hole 203, with its dimensions adapted to the inner cavity of the longitudinal hole 203. When a lever 52 is located within a transverse hole 202, the connecting rod 53 is also simultaneously located within a longitudinal hole 203, thus sealing the longitudinal hole 203.

[0044] The lever 52 includes a main rod 521, a stepped portion 522, and a filling portion 523. The main rod 521 is a cylindrical structure and is fixedly mounted on the rotating frame 51. One side of the stepped portion 522 has a stepped structure and is integrally formed on the periphery of the main rod 521. The filling portion 523 has a planar area and is integrally formed on the periphery of the main rod 521. This planar area is flush with the inner wall of the cavity of the sliding groove 2.

[0045] like Figure 11 As shown, when the main rod 521 slides into the horizontal hole 202 located below, the step portion 522 extends into the cavity of the sliding groove 2; the stepped surface of the step portion 522 faces upward, and the length of the step portion 522 extending into the sliding groove 2 is small; if the squid slides down with its body facing forward, the step portion 522 will not hinder the squid from sliding down; if the squid slides down with its tentacles facing forward, the step portion 522 applies a transverse shearing force to the sliding squid tentacles, causing multiple tentacles to slide and disperse relative to each other along the width direction of the sliding groove 2, breaking the original clustered state, and significantly improving the locking reliability between the tentacles and the stop rod 42.

[0046] like Figure 12 As shown, when the main rod 521 slides into the horizontal hole 202 located above, the planar area of ​​the filling part 523 is flush with the inner wall of the sliding groove 2, realizing the partial filling of the gap between the main rod 521 and the horizontal hole 202; while a certain slender gap is still left between the main rod 521 and the horizontal hole 202, which can also guide the tentacles laterally, further improving the interlocking effect between the tentacles and the stop bar 42.

[0047] like Figure 11 As shown, the side of the step portion 522 that faces away from the stepped surface is an arc surface; as Figure 12 As shown, the side of the filling part 523 that abuts against the inner wall of the transverse hole 202 is also an arc surface, and the center of both coincides with the axis of the rotating frame 51; correspondingly, the inner wall of the transverse hole 202 is also an arc surface, so that the step part 522 and the filling part 523 fit more closely with the transverse hole 202.

[0048] like Figure 3 and Figure 5As shown, the slide trough 2 includes a U-shaped frame 21, a width adjustment plate 22, multiple nuts 23, multiple screws 24, a first support plate 25, a second support plate 26, and a sliding shaft 27; wherein, the U-shaped frame 21 is inclined and forms the main load-bearing frame of the slide trough 2, and the sliding hole 201 is opened in the U-shaped frame 21.

[0049] The width adjustment plate 22 is located inside the cavity of the U-shaped frame 21 and is set parallel to and of the same specifications as the side wall of the U-shaped frame 21. The nut 23 is rotatably mounted on the U-shaped frame 21. The screw 24 is fixedly mounted on the width adjustment plate 22 and extends along the width direction of the U-shaped frame 21. The end of the screw 24 away from the width adjustment plate 22 extends out of the U-shaped frame 21 and is connected to the nut 23 by threaded engagement. Multiple screws 24 correspond one-to-one with multiple nuts 23. When each nut 23 is rotated synchronously, the screw 24 drives the width adjustment plate 22 to move smoothly along the width direction of the U-shaped frame 21, thereby realizing the adjustment of the width of the cavity of the sliding groove 2, adapting to squid of different body diameters, ensuring that a single squid is always in a controlled and limited state during the sliding process, avoiding posture deviation or overturning and loss of control due to excessive gap, and also preventing squeezing damage caused by excessive gap.

[0050] like Figure 5 As shown, the first support plate 25 is fixedly disposed within the sliding hole 201 at the end away from the nut 23; the second support plate 26 is fixedly disposed on the width adjustment plate 22 and slidably disposed within the sliding hole 201; the sliding shaft 27 is fixedly disposed on the first support plate 25 and slidably connected to the second support plate 26; the spring 43 is sleeved on the sliding shaft 27, with one end of each spring 43 abutting against two opposite sides of the slide frame 41, and the other end abutting against the first support plate 25 and the second support plate 26, respectively. When the position of the width adjustment plate 22 is adjusted, the second support plate 26 moves synchronously with the width adjustment plate 22, the sliding shaft 27 slides relative to the second support plate 26, and the two springs 43 are synchronously compressed or released, so that the preload force on the two springs 43 always remains equal, thereby ensuring that no matter how the cavity width changes, the slide frame 41 can automatically return to the geometric center position in the width direction of the sliding groove 2 under the symmetrical elastic force of the springs 43, thus keeping the stop bar 42 stably centered and maintaining its reference consistency for squid posture recognition and limiting.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
