DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0048] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0049] See also Figures 1 to 11 In an embodiment of the present invention, a fish head cutting device based on automatic discharge includes: a workbench 1, a driving assembly, a connecting plate 11 and a second convex shaft 1302, so that after cutting is completed, the rotating connection between the first supporting plate 2 and the second supporting plate 3 can move upward, so that the first supporting plate 2 and the second supporting plate 3 are tilted and bent, and at the same time, a large gap can be formed between the first supporting plate 2, the second supporting plate 3 and the workbench 1, so that the fish body and the fish head slide toward the two sides of the workbench 1 respectively, and slide out of the workbench 1 through the gap, thereby realizing automatic sorting of the fish body and the fish head, preventing the need for subsequent secondary sorting due to the mixing of the fish body and the fish head after cutting, and reducing the production cost, as follows:

[0050] A rectangular through slot is formed on the workbench 1, and a support plate capable of bending upward is provided on the workbench 1, the support plate comprising a first supporting plate 2 and a second supporting plate 3 which are rotatably connected, a sliding connection member 4 is rotatably installed on one end of the first supporting plate 2 away from the second supporting plate 3 and one end of the second supporting plate 3 away from the first supporting plate 2, and the sliding connection member 4 can slide on the side wall of the rectangular through slot;

[0051] The workbench 1 is also provided with a guide plate 101, on which a slider 5 is slidably mounted, one side of the slider 5 is provided with a first convex shaft 501, and the other side is connected to the rotation connection of the first supporting plate 2 and the second supporting plate 3;

[0052] In the initial state, the slider 5 is at the lower end of the guide plate 101, and the first supporting plate 2 and the second supporting plate 3 are in a horizontal state. The fish with the head to be removed can be placed on the first supporting plate 2 and the second supporting plate 3, and the placement direction of the fish can refer to the arrow direction of the first supporting plate 2. The fish body can be placed on the second supporting plate 3, and the second supporting plate 3 is provided with a drain hole to drain the water stains on the fish body to prevent the fish body from shifting during cutting.

[0053] After the cutting is completed, when the slider 5 moves upward along the length direction of the guide plate 101 driven by the driving assembly, the rotating connection between the first supporting plate 2 and the second supporting plate 3 can move upward with the slider 5, so that the first supporting plate 2 and the second supporting plate 3 are bent. At this time, the end of the first supporting plate 2 away from the second supporting plate 3 and the end of the second supporting plate 3 away from the first supporting plate 2 can move toward the slider 5, so that a larger gap is formed between the ends of the first supporting plate 2 and the second supporting plate 3 away from each other and the workbench 1, so that the fish head and the fish body can slide to both sides respectively and slide out of the workbench 1 along the gap. Since the fish body and the fish head slide toward the two sides of the workbench 1, the fish body and the fish head can be automatically sorted, preventing the need for subsequent secondary sorting due to the mixing of the fish body and the fish head after cutting.

[0054] Through the above arrangement, after the cutting is completed, the rotating connection between the first supporting plate 2 and the second supporting plate 3 can move upward, so that the first supporting plate 2 and the second supporting plate 3 are tilted and bent. At the same time, a larger gap can be formed between the first supporting plate 2, the second supporting plate 3 and the workbench 1, so that the fish body and the fish head can slide toward the two sides of the workbench 1 respectively, and slide out of the workbench 1 through the gap, thereby realizing automatic sorting of the fish body and the fish head, preventing the need for subsequent secondary sorting due to the mixing of the fish body and the fish head after cutting, thereby reducing production costs.

[0055] See also Figure 3 , Figure 7-Figure 8 , Fig.10 , Fig.11 The connecting plate 11 is connected to the driving assembly, and a lifting structure capable of moving in the horizontal direction is provided on the connecting plate 11. The lifting structure cooperates with the first convex shaft 501 to enable the bending part of the supporting plate to move upward;

[0056] The lifting structure includes a fixed block 1103 disposed on the connecting plate 11, a lifting rod 13 is slidably mounted on the fixed block 1103, and a third inclined surface 1303 is disposed at one end of the lifting rod 13 facing the first convex shaft 501;

[0057] The lifting rod 13 is formed with a limiting portion 1301 adapted to the fixing block 1103, and the lifting rod 13 and the fixing block 1103 are connected via a first spring 14;

[0058] The second protruding shaft 1302 is disposed on the lifting rod 13. After the second protruding shaft 1302 moves upward to a predetermined position at the bend of the supporting plate, it can cooperate with the triggering member 12 disposed on the workbench 1 to separate the lifting structure from the first protruding shaft 501.

[0059] The side of the trigger member 12 facing away from the first protruding shaft 501 is formed by two groups of second inclined surfaces 1201 , and a protruding portion 1202 facing away from the first protruding shaft 501 is formed between the two groups of second inclined surfaces 1201 .

[0060] In the initial state, the first spring 14 is in a stretched state, at which time the limiting portion 1301 is in contact with the fixing block 1103. During cutting, the connecting plate 11 drives the lifting rod 13 to move downward until the third inclined surface 1303 on the lifting rod 13 contacts the first convex shaft 501. The third inclined surface 1303 cooperates with the first convex shaft 501 to make the lifting rod 13 give way (see FIG. Fig.10 ), until the lifting rod 13 is located at the lower part of the first protruding shaft 501, the first spring 14 can make the limiting part 1301 abut against the fixing block 1103 again, so as to realize the resetting of the lifting rod 13, and then when the connecting plate 11 moves upward, the lifting rod 13 can act on the first protruding shaft 501 to make the slider 5 move upward, so as to realize the bending of the first supporting plate 2 and the second supporting plate 3.

[0061] When the fish body and the fish head slide out of the workbench 1, the second protruding shaft 1302 will abut against one of the second inclined surfaces 1201 on the trigger member 12 (see Fig.11 ), at this time, the two cooperate to enable the lifting rod 13 to move away from the first convex shaft 501. After the second convex shaft 1302 moves to the protrusion 1202, the lifting rod 13 is completely separated from the first convex shaft 501. At this time, under the action of gravity, the first supporting plate 2 and the second supporting plate 3 can be restored.

[0062] Through the above-mentioned arrangement, the lateral reciprocating motion of the lifting rod 13 can be realized, and when cooperating with the first protruding shaft 501, the lifting and release of the first protruding shaft 501 can be realized. On the one hand, the first supporting plate 2 and the second supporting plate 3 can be bent and tilted to unload the fish body and head. On the other hand, the first supporting plate 2 and the second supporting plate 3 can be automatically reset, thereby realizing continuous production.

[0063] See also Figure 5-6 , the driving assembly is arranged on the workbench 1, and the driving assembly is connected with a cutter 8 for cutting fish heads;

[0064] The driving assembly includes an electric telescopic rod 6 installed on the workbench 1, the action end of the electric telescopic rod 6 is connected to a lifting frame 7, the lifting frame 7 is connected to the connecting plate 11, and the cutter 8 is slidably connected to the lifting frame 7;

[0065] The driving assembly further comprises a guide structure connected to the cutter 8, wherein the guide structure can move along the length direction of the lifting frame 7 when the cutter 8 moves downward, and the guide structure comprises a driving plate 10 fixedly mounted on the workbench 1 and a connecting plate 9 penetrating the lifting frame 7 and connected to the cutter 8, wherein a guide shaft 901 is rotatably mounted on one end of the connecting plate 9 away from the cutter 8;

[0066] The driving plate 10 is further provided with an inclined groove 1002 , and the upper end of the inclined groove 1002 is connected to an introduction groove 1001 that penetrates the driving plate 10 and opens upward.

[0067] After the fish is placed, the electric telescopic rod 6 can drive the lifting frame 7 to move downward. After the lifting frame 7 moves downward to a predetermined position, the guide shaft 901 can enter the inclined groove 1002 under the guidance of the introduction groove 1001. At this time, the cutter 8 follows the lifting frame 7 to move downward, and can also move along the length direction of the lifting frame 7 under the cooperation of the inclined groove 1002 and the guide shaft 901, so that the cutter 8 has a horizontal cutting action when cutting the fish head. Compared with the traditional vertical cutting, the cooperation of vertical cutting and horizontal cutting can, on the one hand, save effort to cut the fish meat and cut off the fish bones, thereby reducing the load of the electric telescopic rod 6, and on the other hand, it can reduce the speed of blunting of the cutter 8 and improve the durability of the device.

[0068] See also Figure 1 , Figure 2 , Figure 8-Figure 9 The fish head cutting device based on automatic discharge further includes: a follower frame 16, a support assembly and a side plate 15, wherein the trigger member 12 is fixedly mounted on the side plate 15.

[0069] The follower frame 16 is connected to the workbench 1 through a telescopic guide rod 20. A plurality of pressure structures are equidistantly arranged on the follower frame 16. The pressure structures include a hysteresis sleeve 17 detachably mounted on the follower frame 16. A pressure rod 19 is slidably mounted in the hysteresis sleeve 17. The pressure rod 19 is connected to the hysteresis sleeve 17 through a second spring 18.

[0070] The support assembly is connected to the follower frame 16, and a coaxial groove wheel 24 and a third cam 25 are installed at one end of the support assembly away from the follower frame 16. The support assembly includes a transverse sleeve 21 fixedly connected to the follower frame 16, and a connecting rod 23 is slidably installed in the transverse sleeve 21, and the connecting rod 23 is connected to a third spring 22 arranged in the transverse sleeve 21;

[0071] The groove wheel 24 and the third convex shaft 25 are rotatably connected to an end of the connecting rod 23 away from the third spring 22;

[0072] The third protruding shaft 25 is adapted to the retardation groove provided on the connecting plate 11. After the follower frame 16 moves to a predetermined position, the third protruding shaft 25 can be separated from the retardation groove. Specifically, a first inclined surface 1101 and a horizontal surface 1102 are provided on the inner wall of the retardation groove.

[0073] The side plate 15 is connected to the workbench 1 . A guide groove is formed on the side plate 15 . The groove wheel 24 can roll in the guide groove. The guide groove includes a vertical groove 1501 and a horizontal groove 1502 provided on the side plate 15 .

[0074] In the initial state, the third cam 25 is in the lag groove, and the groove wheel 24 is at the upper end of the vertical groove 1501. At this time, the third cam 25 is in contact with the horizontal plane 1102, so that the follower frame 16 can be lifted, thereby ensuring the stability of the follower frame 16, and having a larger gap between the pressure rod 19 and the second supporting plate 3, which is convenient for placing fish.

[0075] When the cutting action is performed, the lifting frame 7 will move downward, and the follower frame 16 will also move downward. At this time, since the groove wheel 24 moves along the vertical groove 1501, the third cam 25 is restricted in the retardation groove. At this time, the follower frame 16 can follow the lifting frame 7 to move downward until the pressure rod 19 abuts against the fish body. At the same time, the pressure rod 19 moves relative to the retardation sleeve 17, and the third spring 22 is compressed, so that the pressure rod 19 has a force acting on the fish body to fix the fish body.

[0076] Furthermore, since multiple groups of pressure structures are provided, the pressure rods 19 can act on the fish body at equal intervals. On the one hand, this can increase the number of force points on the fish body. On the other hand, each pressure rod 19 moves according to the shape of the fish body and fits the fish body. The combination of these two aspects makes the fish body more stable in a fixed state.

[0077] After the follower frame 16 descends to a predetermined height, the groove wheel 24 moves to the lower end of the vertical groove 1501, and the groove wheel 24 abuts against the lower side wall of the horizontal groove 1502. In this state, when the connecting plate 11 continues to move downward, the third cam 25 can cooperate with the first inclined surface 1101 to make the groove wheel 24 move along the horizontal groove 1502 and compress the third spring 22. At the same time, the third cam 25 abuts against the side of the connecting plate 11, so that when the connecting plate 11 continues to move downward, the height of the third cam 25 will remain unchanged, thereby keeping the height of the follower frame 16 unchanged, ensuring that the pressure rod 19 clamps the fish body and improving the stability of the fish body.

[0078] It should be noted that when the pressure rod 19 acts on the fish body, the fish body is subjected to force so that the other side of the fish body can be squeezed and partially sunk into the drain hole, so as to further improve the stability of the fish body.

[0079] When the connecting plate 11 moves upward, when the retardation groove is aligned with the third cam 25, the third spring 22 will push out the sheave 24 by releasing elastic potential energy. At this time, the sheave 24 can enter the vertical groove 1501 along the horizontal groove 1502. Then the third cam 25 abuts against the horizontal plane 1102 and moves vertically upward along the vertical groove 1501 with the connecting plate 11, causing the follower frame 16 to move upward until the pressure rod 19 separates from the fish body and rises to a predetermined height.

[0080] It is worth noting that during the downward movement of the cutter 8 and the connecting plate 11, the cutter 8 will fit against the connecting portion of the fish body and the fish head and perform the cutting action, so that the fish body can be best fixed during cutting.

[0081] Through the above arrangement, before the cutter 8 descends and performs the cutting action, the follower frame 16 can follow the downward movement and fix the fish body with the cooperation of the pressure rod 19 and the second supporting plate 3. At the same time, the third cam 25 and the groove wheel 24 make way for the side of the connecting plate 11 to abut against the follower frame 16 to maintain a constant height when the cutter 8 continues to descend and perform the cutting action, thereby maintaining the clamping of the fish body.

[0082] As an embodiment of the present invention, a canned fish processing device is also provided, comprising the fish head cutting device.
