[0001] The present application relates to the technical field of eel processing, and in particular to an eel fillet threading machine. Background Art

[0002] In the process of processing eels into food, after the eels are cut into slices, they can be skewered for the convenience of consumers. In order to enable mass production, automatic skewering machines are already available on the market.

[0003] The current skewering machine is described in the utility model with application number CN201720044650.5. The skewering machine includes a conveying mechanism for conveying eels, a skewering mechanism and a pressing mechanism. The conveying mechanism includes a conveyor belt and a conveyor plate placed on the conveyor belt. The pressing mechanism includes a pressure plate and a cylinder that drives the pressure plate to move up and down. The pressure plate and the conveyor plate cooperate to fix the eel fillet, and the skewering mechanism inserts the skewers into the eel fillet.

[0004] Regarding the above-mentioned related technologies, the thickness of eels is different, and the downward pressure of the cylinder needs to be adjusted frequently so that the downward pressure mechanism can press down the eel slices without excessively pressing down the eel slices. The flexibility of the skewer machine when processing eels needs to be improved. Utility Model Content

[0005] In order to enable the threading machine to adapt to eels of different thicknesses, the present application provides an eel fillet threading machine.

[0006] The present application provides an eel fillet threading machine, which adopts the following technical solution:

[0007] An eel fillet threading machine includes a threading mechanism, a conveying mechanism and a pressing mechanism, the conveying mechanism includes a conveyor belt, the pressing mechanism includes a lifting seat, a driving source for driving the lifting seat to move up and down, a pressure plate slidably installed on the lifting seat, and an elastic component for driving the pressure plate to always have a downward movement trend installed on the lifting seat. The elastic component includes a compression spring and a driving rod, the driving rod passes through the lifting seat and is slidably connected to the lifting seat, the lower end of the driving rod is fixedly connected to the pressure plate, and the compression spring is sleeved on the driving rod.

[0008] By adopting the above technical solution, the downward pressure mechanism achieves stable downward pressure on the eel fillet through the coordinated action of the lifting seat, drive source, pressure plate, and elastic component. The elastic component (including the compression spring and drive rod) ensures that the pressure plate always has a downward movement tendency, thereby stably pressing the eel fillet on the conveyor belt and preventing it from slipping or shifting during the skewering process. The pressure plate also appropriately compresses the compression spring according to the thickness of the eel, accommodating eel fillets of varying thicknesses without over-compressing the eel fillet, thereby improving the accuracy and efficiency of skewering.

[0009] Optionally, the pressing plate is a sheet-like structure, the width direction of the pressing plate is vertically arranged, the length direction of the pressing plate is the same as the conveying direction of the conveyor belt, and a plurality of pressing plates are arranged at intervals.

[0010] By adopting this technical solution, the pressing plates can be evenly distributed above the conveyor belt, pressing the eel fillets at multiple points, further improving the stability and accuracy of skewering. At the same time, the design of multiple pressing plates also increases the processing capacity of the equipment and improves production efficiency.

[0011] Optionally, two ends of the pressure plate in the length direction correspond to a group of elastic components respectively.

[0012] By adopting the above technical solution, the pressing plate can distribute the force more evenly when under pressure, avoiding deformation or damage to the pressing plate caused by concentrated force. At the same time, it also improves the pressing effect of the pressing plate on the eel fillet, making the skewering process smoother.

[0013] Optionally, a protrusion extends from the side wall of the pressure plate, and the driving rod is threadedly connected to the protrusion.

[0014] By adopting the above technical solution, when the two driving rods of a pressure plate are rotated at the same time, the height position of the pressure plate can be fine-tuned, and the connection between the pressure plate and the driving rod is made more firm and reliable, avoiding the pressure plate from falling off or shifting due to loose connection; at the same time, it also facilitates the disassembly and replacement of the pressure plate.

[0015] Optionally, the driving rod is threadedly connected to an adjusting block, and one end of the compression spring close to the pressure plate abuts against the adjusting block.

[0016] By adopting the above technical solution, users can adjust the preload of the compression spring according to actual needs, thereby achieving precise control of the downward pressure of the pressure plate; this adjustability improves the adaptability and flexibility of the equipment, meeting the needs of threading eel fillets of different specifications and thicknesses.

[0017] Optionally, the lifting seat can also be detachably installed with a mounting plate, and a pressure mechanism is installed on the mounting plate. The pressure mechanisms are distributed in a rectangular array, and a row of pressure mechanisms is close to one of the pressure plates. The pressure mechanism includes a pressure block, a pressure rod and a pressure spring. The pressure rod passes through the mounting plate and is slidably installed on the mounting plate. The upper end of the pressure rod is installed with a limit block for limiting the pressure rod from downwardly detaching from the mounting plate. The lower end of the pressure rod is fixedly connected to the pressure block, and the pressure spring is sleeved on the pressure rod.

[0018] By adopting the above technical solution, the pressure plate can also press down on the eel fillets. The detachable setting of the pressure mechanism enables the pressure mechanism to be flexibly installed and disassembled as needed, making it convenient for users to adjust according to production needs; at the same time, the rectangular array distribution of the pressure mechanism also improves the processing capacity of the equipment, making the threading process more efficient.

[0019] Optionally, the pressurizing mechanism further includes a pin, one end of which is fixedly mounted on the mounting plate, and the other end of which passes through the pressurizing block for contacting the eel fillet, and the pressurizing block and the pin are in a sliding connection relationship.

[0020] By adopting the above technical solution, the pressure block can apply pressure while the needle can penetrate the eel fillet, further fixing the position of the eel fillet, preventing displacement during the skewering process, and improving the accuracy and stability of skewering.

[0021] Optionally, the pressure block is provided with a recess for the string of skewers to pass through.

[0022] By adopting the above technical solution, the skewers can smoothly pass through the eel meat under the pressure block.

[0023] Optionally, the limiting block and the pressure rod are threadedly connected.

[0024] By adopting the above technical solution, the height position of the pressure block and the preload force of the pressure spring can be appropriately adjusted to meet the requirements of skewering eel slices of different specifications and thicknesses.

[0025] In summary, this application has at least one of the following beneficial effects:

[0026] 1. Through the synergistic effect of the downward pressure mechanism and the pressure mechanism, this eel fillet threading machine achieves stable compression and fixation of the eel fillets, improving the accuracy and efficiency of threading. At the same time, the distribution of multiple pressure plates and pressure mechanisms also increases the processing capacity of the equipment, making the threading process more efficient.

[0027] 2. The skewer's design features an adjustment block, a removable mounting plate, and threaded limit blocks, allowing for precise control of both downward and upward pressure, as well as flexible installation and removal of the pressure mechanism. This design enhances the machine's adaptability and flexibility, meeting the demands of skewering eel fillets of varying sizes and thicknesses. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The present application embodiment discloses an eel fillet threading machine. Figure 1 An eel fillet skewering machine includes a skewering mechanism 100, a conveyor mechanism 200, and a pressing mechanism 300. The conveyor mechanism 200 includes a conveyor belt 210, a conveyor plate placed on the conveyor belt 210, and a workbench 500 provided next to the conveyor belt 210. The skewering mechanism 100 is mounted on the workbench 500. When an eel fillet approaches the skewering mechanism 100 along the conveyor belt 210, the pressing mechanism 300 presses down on the eel fillet. The conveyor plate provides support, and the pressing mechanism 300 prevents the eel fillet from shifting when the skewer is inserted. The skewering mechanism 100 and the conveyor mechanism 200 are not modified in this embodiment of the application, so they will not be described in detail.

[0036] Reference Figure 2 The pressing mechanism 300 of the present embodiment includes a lifting base 310 positioned above the conveyor belt 210, a driving source 320 for driving the lifting base 310 up and down, and a pressing plate 330 slidably mounted on the lifting base 310. A mounting frame 510 is mounted on the workbench 500. The driving source 320 is a pneumatic cylinder fixedly mounted on the mounting frame 510. A mounting frame 520 is slidably mounted on the mounting frame 510. The mounting frame 520 is fixedly connected to the piston rod of the pneumatic cylinder.

[0037] Reference Figure 3Specifically, the lifting base 310 includes two long side panels 311 and two short side panels 312. The two long side panels 311 and the two short side panels 312 are spliced ​​to form a rectangular frame structure with upper and lower openings. The height of the long side panels 311 of the lifting base 310 is lower than the height of the short side panels 312 of the lifting base 310. The two short side panels 312 of the lifting base 310 are fixed to the installation frame 520 by bolts.

[0038] Reference Figure 4 and Figure 5 An elastic component 340 is installed on the lifting seat 310 to drive the pressing plate 330 to always have a downward movement trend. When the lifting seat 310 approaches the eel slice downward and the pressing plate 330 contacts the eel slice, the elastic component 340 drives the pressing plate 330 to press the eel slice downward. According to the thickness of the eel slice, the pressing plate 330 squeezes the elastic component 340 to different degrees, so that the pressing plate 330 can flexibly adapt to eel slices of different thicknesses, which can both press the eel slice downward and reduce excessive squeezing of the eel slice.

[0039] Specifically, refer to Figure 5 The elastic assembly 340 includes a compression spring 341 and a drive rod 342. The compression spring 341 is sleeved onto the drive rod 342. A long plate 313 extends from the upper end of each long side plate 311. The drive rod 342 passes through the long plate 313. The pressure plate 330 and the short side plate 312 are parallel to each other, and each pressure plate 330 corresponds to two sets of elastic assemblies 340. The drive rod 342 passes through the long plate 313 and is connected to the long plate 313 for vertical sliding. The upper end of the drive rod 342 is fixedly connected to a boss 343, which restricts the drive rod 342 from moving downward away from the long plate 313. The side walls of the pressure plate 330 are fixedly connected to a protrusion 331. The lower end of the drive rod 342 is threadedly connected to the protrusion 331. By rotating the two drive rods 342 simultaneously, the distance between the pressure plate 330 and the conveyor belt 210 can be slightly adjusted.

[0040] Reference Figure 4 and Figure 5 The pressing plate 330 is a sheet-like structure. The width direction of the pressing plate 330 is vertically arranged, and the thickness of the pressing plate 330 is in contact with the eel slices. The end of the pressing plate 330 in the length direction is close to the long side plate 311. The long side plate 311 is provided with a guide groove 314 for accommodating the pressing plate 330. The pressing plate 330 moves up and down along the guide groove 314. The length direction of the pressing plate 330 is the same as the length direction of the conveyor belt 210. Multiple pressing plates 330 are arranged at intervals along the length direction of the long strip 313. The independent setting of multiple pressing plates 330 can press down eel slices of different areas, and the pressing plate 330 in contact with the eel slice presses down the compression spring 341. The height position of each pressing plate 330 can also be adjusted independently to further flexibly adapt to eel slices of different thicknesses.

[0041] More specifically, see Figure 5An adjustment block 350 is threadedly connected to the drive rod 342. The upper end of the compression spring 341 abuts the lower surface of the elongated plate 313, while the lower end of the compression spring 341 abuts the adjustment block 350. The degree of compression of the compression spring 341 can be adjusted by rotating the adjustment block 350. When the compression spring 341 is highly compressed, the pressure plate 330 has less room to press the compression spring 341 upward, making it suitable for pressing down on thinner eel fillets. When the drive rod 342 rotates and is threadedly connected to the protrusion 331, the adjustment block 350 rotates with the rotation of the drive rod 342.

[0042] Further, refer to Figure 3 The lifting seat 310 is detachably mounted with a mounting plate 360 ​​, on which a pressurizing mechanism 400 is mounted. The mounting plate 360 ​​and the short side plate 312 are connected by bolts. If the mounting plate 360 ​​is removed, the pressurizing mechanism 400 is also removed.

[0043] Reference Figure 5 The pressure mechanism 400 includes a pressure block 410, a pressure rod 420, and a pressure spring 430. The pressure spring 430 also uses a compression spring 341. The pressure rod 420 passes through the mounting plate 360 ​​and is slidably mounted on the mounting plate 360. A limit block 421 is installed on the upper end of the pressure rod 420 to limit the pressure rod 420 from disengaging downward from the mounting plate 360. The limit block 421 is threadedly connected to the pressure rod 420. The position of the limit block 421 is different, and the elastic force of the pressure spring 430 on the pressure block 410 can be adjusted, and the height position of the pressure block 410 can also be adjusted. The lower end of the pressure rod 420 is fixedly connected to the pressure block 410. The pressure spring 430 is sleeved on the pressure rod 420, one end of the pressure spring 430 abuts on the mounting plate 360, and the other end of the pressure spring 430 abuts on the pressure block 410.

[0044] When the pressure block 410 presses down the eel slice, the pressure block 410 appropriately squeezes the pressure spring 430 according to the thickness of the eel slice. The setting of the pressure block 410 can further stabilize the eel slice, making it easier for the skewers to be inserted into the eel slice.

[0045] Reference Figure 5 Furthermore, the pressure mechanism 400 also includes a pin 440, one end of which is fixedly mounted on the mounting plate 360, and the other end of the pin 440 passes through the pressure block 410 for contacting the eel fillet. There are two pins 440 corresponding to one pressure block 410, and the pins 440 can be inserted into the eel meat and can also guide the up and down movement of the pressure block 410. When the pressure block 410 and the lower end of the pressure plate 330 abut against the eel fillet, the pressure block 410 presses the pressure spring 430 upward, and the pin 440 is inserted into the eel meat, which can further fix the eel fillet and ensure that the skewers can be inserted into the eel fillet.

[0046] Reference Figure 4 The pressure mechanisms 400 are arranged in a rectangular array, with a row of pressure mechanisms 400 located near a pressure plate 330. The skewer mechanism of the present application allows three skewers to simultaneously pass through a piece of eel fillet. Therefore, the embodiment of the present application includes three pressure mechanisms 400 in a row of pressure mechanisms 400, with one pressure mechanism 400 corresponding to each skewer. Since the pressure block 410 squeezes the eel meat when pressing down, in order to prevent the pressure block 410 from interfering with the skewers' entry into the eel meat, a clearance slot 411 is provided in the pressure block 410 for the skewers to pass through.

[0047] The implementation principle of the eel fillet threading machine in the embodiment of the present application is as follows:

[0048] The lifting seat 310 is lifted and lowered by the driving source 320. When the eel fillet needs to be pressed, the driving source 320 drives the lifting seat 310 downward, so that the pressure plate 330 contacts the eel fillet; when the eel fillet needs to be released, the driving source 320 drives the lifting seat 310 upward, so that the pressure plate 330 separates from the eel fillet; when the pressure plate 330 and the pressure block 410 are subjected to pressure, the compression spring 341 and the pressure spring 430 are deformed and store energy; when the pressure disappears, the compression spring 341 releases energy and pushes the pressure plate 330 back to its original position, and the pressure spring 430 releases energy and pushes the pressure block 410 back to its original position; this design ensures that the pressure plate 330 and the pressure block 410 always have a downward trend and maintain a certain downward pressure, thereby achieving stable compression of eel fillets of different thicknesses; the design of the pin 440 can further fix the position of the eel fillet to prevent it from shifting or flipping during the threading process.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
