Description

Technical Field

[0001] This utility model relates to the field of fish processing technology, and in particular to an improved automatic fish-killing machine. Background Technology

[0002] Fish meat is tender and delicious, and is a high-quality source of protein. The use of automatic fish-killing machines for large-scale commercial slaughtering of fish has become an indispensable process in fish processing.

[0003] Chinese utility model patent CN115119869B discloses a flexible descaling and cutting machine, including a frame and a self-adjusting feeding device, a dorsal descaling device, a pressing and conveying device, a fish body descaling device, a cutting device, and a discharge device mounted on the frame. The self-adjusting feeding device is located on one side of the frame, the dorsal descaling device is located on the outlet side of the self-adjusting feeding device, and the pressing and conveying device is located on the outlet side of the dorsal descaling device. The fish body descaling device and the cutting device are arranged sequentially along the conveying direction in the conveying area of ​​the pressing and conveying device, and the discharge device is located at the end of the conveying of the pressing and conveying device. This invention has the advantages of high automation, good processing quality, and good versatility.

[0004] However, its shortcomings are: its belly and back descaling device uses a flexible disc-shaped spiral descaling spring as the blade support blade, which is prone to breakage during use and has high maintenance costs. At the same time, its cutting device is prone to causing the fish to shift during operation and not be completely cut open, resulting in the fish needing to be processed repeatedly. Utility Model Content

[0005] The purpose of this invention is to provide an improved automatic fish-killing machine with a descaling structure that is not easily broken and is easy to replace. The cutting device can be adjusted up and down to accommodate fish of different sizes.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an improved automatic fish-killing machine, including a frame, with a self-adjusting feeding device and a discharge port respectively arranged on opposite sides of the frame, and a four-way pressing and conveying mechanism for conveying fish arranged inside the frame along the direction from the self-adjusting feeding device to the discharge port, and a belly and back scaling mechanism, a side scaling mechanism and a self-adjusting splitting mechanism arranged sequentially inside the frame along the conveying direction of the four-way pressing and conveying mechanism.

[0007] By adopting the above technical solution, the fish to be processed enters the machine frame from the self-adjusting feeding device, and is conveyed from the self-adjusting feeding device to the discharge port by the four-way pressing and conveying mechanism. During the conveying process, the scales on the belly and back are removed by the belly and back descaling mechanism, the scales on the sides are removed by the side descaling mechanism, and the fish is split in half by the self-adjusting splitting mechanism to facilitate further processing.

[0008] A further feature of this invention is that the self-adjusting feeding device includes a lower feeding trough fixed on the frame, an upper pressing trough is arranged opposite to the lower feeding trough, the upper pressing trough is longitudinally movably connected to a descaling guide rod, and a pressing spring is arranged on the outside of the guide rod above the upper pressing trough.

[0009] By adopting the above technical solution, the upper pressure trough continuously presses the fish body downward under the action of the downward pressure spring set on the outside of the guide rod, which can fix the position of the fish and clamp the fish so that it does not fall.

[0010] The present invention is further configured such that: the descaling mechanism includes a descaling roller rotatably connected to the end of the lower feeding trough and an upscaling roller rotatably connected to the end of the upper pressing trough. The descaling roller is connected to a first motor fixed on the frame via a transmission belt, and the upscaling roller is connected to a second motor fixed on the upper pressing trough via a transmission belt.

[0011] By adopting the above technical solution, after the fish body is fixed up and down by the self-adjusting feeding device, the upper and lower descaling rollers contact the belly and back of the fish. The rotation of the descaling rollers causes the fish scales in contact to be pulled off the fish body. The structure of the descaling rollers is the same as the descaling roller structure in the previously published Chinese utility model patent CN115119869B.

[0012] A further feature of this invention is that the side descaling mechanism includes two parallel rotating descaling parts, each of which is rotatably connected to a descaling mechanism slider at both ends. The descaling mechanism slider is laterally slidably connected to the frame, and a descaling mechanism spacing adjustment spring is provided on both sides of the descaling mechanism slider to adjust the spacing between the two rotating descaling parts.

[0013] By adopting the above technical solution, the interval of the rotating descaling section can be automatically adjusted to accommodate fish of different sizes.

[0014] A further feature of this invention is that the rotary descaling part includes a rotating shaft, one end of which is connected to a side descaling motor. Several sets of flexible descaling sheets are arranged on the outside of the rotating shaft, and a fixing plate for fixing the flexible descaling sheets is also arranged on the outside of the rotating shaft. A sheet protection plate is arranged between the fixing plate and the flexible descaling sheets.

[0015] A further feature of this invention is that the flexible descaling sheet includes a sheet base, and several blade fixing strips are detachably connected to the sheet base. The blade fixing strips are arranged in a comb-like pattern, and a descaling head is fixed to the end of each blade fixing strip.

[0016] By adopting the above technical solution, the motor drives the rotating descaling section to rotate continuously. Due to the curvature of the fish body, the contact time between each blade fixing strip and the fish body is different during high-speed rotation. The descaling head fixed at the end of the blade fixing strip is inserted into the gap between the fish scales and the fish body, pulling out the fish scales during high-speed rotation. The fixing plate fixes the flexible descaling blades and the rotating shaft together. The blade fixing strips are arranged in a comb-like shape, and each blade fixing strip has a certain degree of flexibility. The fixing plate can fix all the blade fixing strips uniformly. The blade fixing strips are connected to the fixing plate by buckles. If a blade fixing strip is damaged, it can be disassembled and replaced individually. The blade protection plate is sandwiched between the fixing plate and the flexible descaling blade. When subjected to force, its deformation degree is different from that of the blade fixing strip. If a blade fixing strip is subjected to excessive force and causes severe deformation during high-speed rotation, the blade protection plate will support one side of the blade fixing strip to share the force and reduce the risk of damage to the blade fixing strip.

[0017] A further feature of this invention is that the self-adjusting slitting mechanism includes a longitudinally movable slitting wheel, a rotating rod axially connected to the slitting wheel, and slitting mechanism guide rods rotatably connected to both ends of the rotating rod. One side of the rotating rod is connected to a slitting mechanism motor fixed on the frame via a transmission belt.

[0018] By adopting the above technical solution, the cutting wheel can be adjusted up and down to accommodate fish of different sizes, and the motor drives the cutting wheel to rotate and cut the fish body through the transmission belt.

[0019] A further feature of this invention is that the four-way pressing and transmitting mechanism includes a first lateral transmitting part disposed between the dorsal descaling mechanism and the side descaling mechanism, a second lateral transmitting part disposed between the side descaling mechanism and the self-adjusting splitting mechanism, and a pressing part disposed above the self-adjusting splitting mechanism. The first lateral transmitting part and the second lateral transmitting part have the same structure.

[0020] By adopting the above technical solution, the first lateral transmission unit and the second lateral transmission unit clamp the fish and slowly rotate it to drive the fish body forward. When it reaches the position of the splitting wheel, the pressing part presses the fish body against the bottom of the frame to prevent the fish body from falling off the lateral transmission unit due to the upward force of the splitting wheel, which would affect the splitting depth.

[0021] A further feature of this invention is that the first lateral transmission section includes two parallel rotating transmission shafts, with transmission section sliders rotatably connected to both ends of the rotating transmission shafts. The transmission section sliders are laterally slidably connected to the frame. Transmission shaft spacing adjustment springs are provided on both sides of the transmission section sliders to adjust the spacing between the two rotating transmission shafts. A transmission section motor is provided at one end of the rotating transmission shafts, and several parallel transmission wheels are axially arranged on the outer side of the rotating transmission shafts.

[0022] By adopting the above technical solution, the distance between the rotating transmission shafts can be automatically adjusted through the cooperation of the transmission section slider and the transmission shaft distance adjustment spring to accommodate fish of different sizes. The parallel transmission wheels clamp the fish body at different heights, enhancing the clamping force and making it more difficult for the fish to fall off.

[0023] A further feature of this invention is that the pressing part includes a pressing rod rotatably connected to the frame at its upper end, a pressing plate at the lower end of the pressing rod for pressing down materials, and pressing springs on both sides of the pressing plate for limiting the position of the pressing part.

[0024] By adopting the above technical solution, the lower pressure plate at the lower end of the pressure rod presses the fish against the bottom of the frame, so that the fish body will not move upwards and affect the depth of the cut when it is cut open.

[0025] The beneficial effects of this utility model are:

[0026] 1. By adding a blade protection clip between the fixed blade and the flexible descaling blade, the stress borne by the blade fixing strip under high-speed rotation conditions is effectively distributed, significantly reducing the risk of breakage. Simultaneously, the split design allows each blade fixing strip to be independently disassembled, greatly improving the ease of replacement and maintenance efficiency after component damage.

[0027] 2. Improved stability and precision in fish gutting: A pressing section is installed above the gutting wheel to reliably press and fix the fish body to the bottom of the frame, effectively preventing the fish from slipping during processing. This structure ensures that each fish can be precisely gutted to the specified depth along a predetermined path, providing a good foundation for subsequent processing steps and improving processing consistency and efficiency.

[0036] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] According to the appendix Figure 1 — Figure 6 The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0038] An improved automatic fish-killing machine includes a frame 1. A self-adjusting feeding device 2 and a discharge port 3 are respectively arranged on opposite sides of the frame 1. A four-way pressing and conveying mechanism 7 for conveying fish is arranged inside the frame 1 along the direction from the self-adjusting feeding device 2 to the discharge port 3. A belly and back descaling mechanism 4, a side descaling mechanism 5 and a self-adjusting splitting mechanism 6 are arranged sequentially inside the frame 1 along the conveying direction of the four-way pressing and conveying mechanism 7.

[0039] The self-adjusting feeding device 2 includes a lower feeding trough 21 fixed on the frame 1, an upper pressing trough 22 is arranged opposite to the lower feeding trough 21, the upper pressing trough 22 is longitudinally movably connected to a descaling guide rod 23, and a pressing spring 24 is arranged on the outside of the guide rod 23 above the upper pressing trough 22.

[0040] When feeding fish, first insert the fish head into the opening of the self-adjusting feeding device, and then grasp the fish tail and push it forward. The fish head is fixed in vertical height under the pressure of the lower feeding trough 21 and the upper pressing trough 22. Then, with the pressure applied to the fish by the four-way pressing and conveying mechanism, it gradually enters the fish killing machine.

[0041] The descaling mechanism 4 includes a descaling roller 41 rotatably connected to the end of the lower feeding trough 21 and an upscaling roller 42 rotatably connected to the end of the upper pressing trough 22. The descaling roller 41 is connected to a first motor 43 fixed on the frame 1 via a transmission belt, and the upscaling roller 42 is connected to a second motor 44 fixed on the upper pressing trough 22 via a transmission belt. The first motor 43 is fixed on the frame at the same height as the descaling roller 41 and provides power to the descaling roller via belt drive. The second motor 44 is fixed above the upscaling roller 42 and moves up and down with the upscaling roller, and provides power to the upscaling roller 42 via belt drive.

[0042] Furthermore, the side descaling mechanism 5 includes two parallel rotating descaling parts 51. The two ends of the rotating descaling parts 51 are rotatably connected to descaling mechanism sliders 52. The descaling mechanism sliders 52 are mounted on the frame 1 in a lateral sliding manner. The frame 1 is provided with a slide groove for the descaling mechanism sliders 52 to slide. Both sides of the descaling mechanism sliders 52 are provided with descaling mechanism spacing adjustment springs 53 to adjust the spacing between the two rotating descaling parts 51. When no fish enters, the adjustment springs 53 at both ends press against each other to keep the descaling mechanism sliders 52 in a balanced position. When a fish enters, the descaling mechanism sliders 52 slide to both sides together with the rotating descaling parts 51. At this time, the inner adjustment spring 53 is stretched by force, and the outer one is shortened by force. The adjustment springs 53 at both ends work together to make the end of the rotating descaling part tightly press against the fish body. When the rotating descaling part 51 rotates, the blade at the end will insert into the gap between the fish scales and the fish body and peel off the fish scales.

[0043] Furthermore, the rotary descaling unit 51 includes a rotating shaft 511, one end of which is connected to a side descaling motor 512. Several sets of flexible descaling blades 54 are arranged on the outside of the rotating shaft 511. A fixing plate 513 for fixing the flexible descaling blades 54 is also arranged on the outside of the rotating shaft 511. A blade protection plate 514 is arranged between the fixing plate 513 and the flexible descaling blades 54. In use, the output rotor of the side descaling motor 512 penetrates the slider 52 of the descaling mechanism and is coaxially connected to the rotating shaft 511 of the rotary descaling unit 51.

[0044] Furthermore, the flexible descaling sheet 54 includes a sheet base 541, on which several blade fixing strips 542 are fixedly connected by bolts. The ends of the blade fixing strips 542 on each sheet are connected together, and the blade fixing strips 542 are arranged in a comb-like pattern. Each blade fixing strip 542 has a descaling head 543 fixed at its end. When the blade fixing strip 542 is severely worn, it can be replaced individually, avoiding the waste caused by replacing the entire flexible descaling sheet 54.

[0045] Furthermore, the self-adjusting slitting mechanism 6 includes a longitudinally movable slitting wheel 61, a rotating rod 62 axially connected to the slitting wheel 61, and slitting mechanism guide rods 63 rotatably connected to both ends of the rotating rod 62. One side of the rotating rod 62 is connected to the slitting mechanism motor 64 fixed on the frame 1 via a transmission belt. The slitting mechanism motor 64 and the slitting wheel 61 move up and down together, and its output rotor drives the rotating rod 62 to rotate via belt transmission.

[0046] Furthermore, the four-way pressing and transmission mechanism 7 includes a first lateral transmission section 71 disposed between the dorsal descaling mechanism 4 and the side descaling mechanism 5, a second lateral transmission section 72 disposed between the side descaling mechanism 5 and the self-adjusting splitting mechanism 6, and a pressing section 73 disposed above the self-adjusting splitting mechanism 6. The first lateral transmission section 71 and the second lateral transmission section 72 have the same structure.

[0047] Furthermore, the first lateral transmission unit 71 includes two parallel rotating transmission shafts 711. Transmission unit sliders 712 are rotatably connected to both ends of the rotating transmission shafts 711. The transmission unit sliders 712 are laterally slidably connected to the frame 1. Transmission shaft spacing adjustment springs 715 are provided on both sides of the transmission unit sliders 712 to adjust the distance between the two rotating transmission shafts 711. A transmission unit motor 713 is provided at one end of the rotating transmission shafts 711. Several parallel transmission wheels 714 are axially arranged on the outer side of the rotating transmission shafts 711. The two ends of the lateral transmission unit have sliders with the same function as the two ends of the descaling mechanism. The spacing adjustment springs 715 provided on both sides of the transmission unit sliders 712 can also cause the lateral transmission unit to clamp the fish sideways when the fish body is squeezed to both sides, generating friction and preventing the fish from slipping through the friction force. When the lateral transmission unit starts to rotate, the fish body moves forward under the action of friction force.

[0048] Furthermore, the pressing part 73 includes a pressing rod 731 rotatably connected to the frame 1 at its upper end, a pressing plate 732 that can press down the material at the lower end of the pressing rod 731, and pressing springs 733 that limit the position of the pressing part 73 on both sides of the pressing plate 732.

[0049] The working method of this utility model is as follows: the fish is put into the machine through the self-adjusting feeding device, the upper feeding trough presses down to fix the fish body, the belly and back descaling mechanism contacts the upper and lower positions of the fish and begins to rotate to peel off the scales, the first lateral conveying part rotates to drive the fish body forward, the side descaling mechanism contacts the side of the fish body and rotates to peel off the fish scales, the second lateral conveying part rotates to continue to drive the fish body forward, the pressing part presses the fish body against the bottom of the frame to prevent the fish body from sticking up, the splitting wheel rotates to cut the fish body into two halves, and the processed fish body goes out from the discharge port.
