Description

Technical Field

[0001] This utility model relates to the field of food testing equipment technology, specifically to a pre-cutting device for testing dried seafood. Background Technology

[0002] Dried seafood products (such as dried fish and dried shellfish) require standardized cutting before quality testing to ensure consistent sample specifications and reliable test data. Existing technologies, such as traditional cutting equipment, often rely on manual operation or semi-automated mechanical structures, which have the following drawbacks: 1. Insufficient positioning accuracy: Samples require manual adjustment after placement, and the lack of reliable clamping mechanisms makes them prone to slippage during cutting, leading to size deviations and affecting the accuracy of test results. 2. Low automation: Operations such as cutting path adjustment and pressure control require frequent manual intervention, resulting in low efficiency, especially for batch testing scenarios where rapid processing is difficult. 3. Poor adaptability: Traditional equipment struggles to adapt to the large differences in hardness and irregular shapes of dried seafood products. For example, fixed pressure plates cannot dynamically adjust clamping force according to sample thickness, easily causing sample breakage or blade wear; the cutting component stroke adjustment relies on mechanical limits, failing to accurately match different specification requirements. 4. Insufficient structural stability: Vibration or friction during cutting component movement can cause displacement deviations, and the lack of sensor feedback mechanisms prevents real-time correction of cutting parameters. In addition, some devices have attempted to improve accuracy by adding guide rails or sensors, but the following problems still exist: for example, the linkage between the tray and the pressure plate is poor, and debris is easily left behind in the cut samples; the blade switching relies on manual operation, which cannot quickly adapt to the needs of multi-specification cutting. Therefore, there is an urgent need for a device that integrates high-precision positioning, automated control, and stable cutting functions to meet the standardized requirements of pre-processing for the testing of dried seafood. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pre-cutting device for dried seafood before testing that has high-precision positioning, automatic control and stable cutting function and meets the standardized requirements of pre-processing for testing dried seafood.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A pre-cutting device for dried seafood before inspection includes a machine body, a positioning component, and a cutting component. The cutting component is located below the machine body and includes a mounting bracket, a connecting handle, and a material tray. The mounting bracket is fixed to both sides of the machine body. A sliding rod and a positioning sensor are mounted on the mounting bracket. Distance sensors are mounted at both ends of the sliding rod. A pneumatic slider is movably connected to the sliding rod. A baffle is fixed to one side of the pneumatic slider. The pneumatic slider is fixedly connected to the connecting handle. A connecting rod is mounted on the connecting handle, and a mounting base is fixed to the connecting rod. A material tray is mounted on the mounting base. The assembly includes a positioning component, which comprises a guide rod, a pressure plate, and a top plate. The guide rod is installed on one side of the material tray, and the pressure plate is slidably connected to the guide rod. One end of the pressure plate is equipped with a telescopic cylinder located below the material tray. The top plate is installed above the machine body and is perpendicular to the material tray and parallel to the pressure plate. A slitting knife assembly module is installed on the machine body, and a clutch module is installed within the slitting knife assembly module. A control panel is installed on the side of the machine body, and the positioning component, cutting component, slitting knife assembly module, and clutch module are all electrically connected to the control panel.

[0006] Furthermore, a baffle is provided on one side of the tray to prevent the sample from shifting laterally.

[0007] Furthermore, a fixed base is provided at the bottom of the machine body, and a wing nut is movably installed between the fixed bases. A movable groove is provided on the machine body, and a fixed rod is provided between the top plate and the wing nut. The fixed rod moves within the movable groove to accommodate samples of different thicknesses. After completion, the nut is locked.

[0008] Furthermore, friction strips are provided on the positioning component, cutting component, and slitting blade module to reduce vibration and prevent debris residue.

[0009] Furthermore, a guide rail is fixed at the bottom of the machine body, an axle is provided on the connecting handle, a guide wheel is movably connected to the axle, and the guide wheel and the guide rail move horizontally relative to each other to ensure that the cutting component 3 moves smoothly.

[0010] Furthermore, the top plate has an angle of less than 75 degrees with the horizontal, and the inclined design can increase the contact surface and prevent the sample from tilting.

[0011] Compared with existing pre-cutting devices for dried seafood before inspection, this invention has at least the following advantages:

[0012] Precise cutting and positioning: The pneumatic slider stroke is controlled by the linkage between the distance sensor and the position sensor on the slide bar. Combined with the clamping design of the pressure plate and the top plate, the sample is firmly fixed and the cutting path error is less than 0.5mm, which significantly improves the consistency of test data.

[0013] Highly efficient automated control: The slitting blade module integrates a clutch module, which can quickly switch between multiple blade sizes; the control panel centrally controls the positioning, cutting and blade switching processes, reducing manual intervention and improving processing efficiency by more than 40%.

[0014] Strong adaptability and stability: The wing nut and movable groove adjust the height of the top plate to accommodate samples of different thicknesses; the guide rail and guide wheel ensure that the cutting component moves horizontally without deviation; the friction strip reduces component vibration, and the tilted design of the top plate (angle <75°) effectively prevents the sample from breaking or sliding.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other. Example

[0027] like Figure 1-7 As shown, the pre-cutting device for dried seafood before inspection according to this utility model includes a body 1, a positioning component 2, and a cutting component 3. The cutting component 3 is installed at the bottom of the body 1. The mounting bracket 4 of the cutting component 3 is fixed on both sides of the body 1. The mounting bracket 4 is provided with a sliding rod 5 and a positioning sensor 8. Distance sensors 9 are configured at both ends of the sliding rod 5. A pneumatic slider 6 is movably connected to the sliding rod 5. A baffle 7 is fixed on one side of the pneumatic slider 6, and the positioning sensor 8 is triggered by the baffle 7 to limit the movement stroke. The pneumatic slider 6 is fixedly connected to a connecting handle 10. A connecting rod 11 is provided on the connecting handle 10. A mounting base 12 is fixed at the end of the connecting rod 11. A material tray 13 is installed on the top of the mounting base 12 for carrying the dried seafood to be cut.

[0028] The positioning assembly 2 includes a guide rod 14, a pressure plate 15, and a top plate 17. The guide rod 14 is vertically fixed to one side of the material tray 13. The pressure plate 15 is slidably connected to the guide rod 14 via a slider. One end of the pressure plate 15 is connected to a telescopic cylinder 16 (located below the material tray 13), which drives the pressure plate 15 to move up and down along the guide rod 14 to clamp the sample. The top plate 17 is fixed above the machine body 1, perpendicular to the material tray 13 and parallel to the pressure plate 15, and the two cooperate to form a sample fixing cavity. A slitting blade assembly module 18 is set in the middle of the machine body 1, which integrates a clutch module 19 for switching different blade assemblies. A control panel 20 is set on the side of the machine body 1, which is electrically connected to the positioning assembly 2, the cutting assembly 3, the slitting blade assembly module 18, and the clutch module 19 to realize automated control. Example

[0029] like Figure 1-7 As shown, the specific implementation method begins with sample placement and positioning:

[0030] Place the dried seafood to be cut on the tray 13. The baffle 21 on one side of the tray 13 prevents the sample from shifting laterally.

[0031] The telescopic cylinder 16 is activated via the control panel 20, driving the pressure plate 15 to move downwards along the guide rod 14, where it engages with the top plate 17 to clamp the sample. The top plate 17 has a 60-degree angle with the horizontal plane; this tilted design increases the contact area and prevents the sample from tilting.

[0032] Secondly, the cutting stroke is adjusted:

[0033] Adjust the wing nut 23: After loosening the wing nut 23, slide the fixed rod 25 along the movable groove 24 to adjust the height of the top plate 17 to accommodate samples of different thicknesses. After completion, tighten the nut.

[0034] Distance sensor 9 monitors the displacement of pneumatic slider 6 on slide bar 5 in real time, and the data is fed back to control panel 20 to automatically calculate the cutting path.

[0035] Then comes the trimming execution:

[0036] The control panel 20 activates the pneumatic slider 6, which moves horizontally along the slide bar 5, causing the connecting handle 10 and the material tray 13 to move synchronously. The guide wheel 29 rolls along the guide rail 27 below the machine body 1, ensuring smooth movement of the cutting assembly 3.

[0037] When the pneumatic slider 6 triggers the position sensor 8, the slitting knife assembly module 18 starts, and the clutch module 19 switches the knife assembly according to the preset mode to complete the multi-specification slitting of the sample.

[0038] Finally, resetting and debris removal:

[0039] After the cutting is completed, the pneumatic slider 6 returns to its initial position, and the pressure plate 15 is lifted by the telescopic cylinder 16 to remove the sample.

[0040] Friction strips 26 provided on the surfaces of positioning component 2, cutting component 3 and slitting blade module 18 can reduce vibration and prevent debris residue.

[0041] This device integrates sensors, pneumatic modules, and an adjustable positioning structure to achieve precise cutting of dried seafood products. It is especially suitable for samples with uneven hardness and irregular shape, significantly improving pre-processing efficiency and data reliability.
