Description

Technical Field

[0001] This invention belongs to the technical field of fish processing equipment, and particularly relates to an integrated processing equipment and method for single-path fish transport. Background Technology

[0002] Fish processing mainly includes three steps: descaling, gutting, and eviscerating. Current processing methods mostly adopt separate steps: first, the scaler removes the scales from the surface of the fish, then the scaled fish is transferred to the gutting machine to cut open the abdominal cavity, and finally it is transported to the eviscerating station to clean the internal organs.

[0003] The step-by-step processing method has the following drawbacks: multiple machines operate independently, and material transfer between processes requires manual intervention or the setting of intermediate conveyor belts; during the transfer process, fish are easily contaminated due to collisions or stacking, affecting the hygiene quality of subsequent processing; the gutting and evisceration processes are usually carried out separately after scaling, and the conveying mechanism of the scaling process is independent of the conveying mechanism of the gutting and evisceration process, making it difficult to achieve synchronous matching of conveying speeds, which can easily lead to fish accumulation or stretching due to speed differences, affecting the smoothness and efficiency of processing. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides an integrated processing equipment and method for fish with single-path conveying. By integrating conveying, descaling, gutting and eviscerating into a single fish conveying path, the entire process of fish processing is integrated and synchronously processed, which greatly improves the compactness of the equipment and the efficiency of fish processing.

[0005] Technical solution: To achieve the above objectives, the present invention provides a fish body single-path conveying integrated processing equipment, including a frame and a conveying and scaling integrated mechanism, a blotting mechanism and a evisceration mechanism respectively disposed on the frame;

[0006] The integrated conveying and scaling mechanism includes a conveying unit and a scaling unit, wherein the scaling unit is used to scrape off fish scales during the process of conveying the fish body by the conveying unit.

[0007] The evisceration mechanism and the visceration mechanism are arranged sequentially along the fish transport path of the transport unit. The evisceration cutting part of the evisceration mechanism and the visceration cleaning part of the visceration mechanism extend into the fish transport space of the transport unit from the bottom, so as to complete the process of cutting open the fish belly and removing the internal organs in sequence on the same transport path during the scaling process.

[0008] Furthermore, the conveying unit includes multiple sets of conveying rollers, and the scaling unit includes multiple sets of scaling rollers. The conveying rollers and the scaling rollers are parallel to each other, and the conveying rollers and the scaling rollers are arranged alternately on the fish conveying path.

[0009] Furthermore, the integrated conveying and scraping mechanism also includes a common frame connecting the frame and supporting the conveying unit and the scraping unit; the common frame is provided with a roller mounting cavity and a roller brush mounting cavity; a roller bearing seat is provided in the roller mounting cavity, and the conveying roller is rotatably mounted on the roller bearing seat; a roller brush bearing seat is provided in the roller brush mounting cavity, and the scraping roller brush is rotatably mounted on the roller brush bearing seat; the rotation of the conveying roller and the rotation of the scraping roller brush are independent of each other, and the rotation of each scraping roller brush is independent of each other.

[0010] Furthermore, a first guide rail and a spring are provided inside the roller mounting cavity; the roller bearing seat is connected to a first slider on the first guide rail, and the roller bearing seat is connected to the inner wall of the roller mounting cavity through the spring; the conveying roller is floating on the common frame by the elastic force provided by the spring, and the floating displacement direction of the conveying roller is perpendicular to the fish conveying path.

[0011] Furthermore, a second guide rail is provided inside the roller brush mounting cavity, and a scale-scraping feed cylinder is provided on the common frame; the roller brush bearing seat is connected to the second slider on the second guide rail; the scale-scraping feed cylinder is connected to the roller brush bearing seat and is used to push the corresponding scale-scraping roller brush toward the fish body so as to contact the surface of the fish scales.

[0012] Furthermore, the conveying unit also includes a chain drive assembly provided with conveying driving force by a conveying motor, and each of the conveying rollers located on the same side of the fish conveying path is connected through the chain drive assembly.

[0013] Furthermore, the scraping unit also includes a scraping motor, which is driven and connected to the scraping roller in a one-to-one correspondence.

[0014] Furthermore, the flank cutting part of the flank cutting mechanism is a flank cutting saw blade, which is mounted on the frame via a saw blade shaft, and a flank cutting motor connected to the saw blade shaft is provided on the frame.

[0015] Furthermore, the dirt removal mechanism has a dirt removal disc brush as its cleaning and sweeping part. The dirt removal disc brush is mounted on the frame via a disc brush shaft, and the frame is equipped with a dirt removal motor that drives and connects to the disc brush shaft.

[0016] A fish processing method using an integrated single-path fish transport processing device includes the following steps:

[0017] Step S1: Loading materials

[0018] The fish to be processed is placed at the starting end of the conveying unit from the feed port of the frame, so that the axis of the fish is parallel to the direction of the fish conveying path;

[0019] Step S2: Simultaneous conveying and descaling processing

[0020] The conveying unit is activated to drive the fish body to move along the fish body conveying path. At the same time, the scaling unit is activated to make the scaling roller brush rotate and contact the surface of the fish body, so that the fish scales are removed synchronously during the fish body conveying process.

[0021] Step S3: Laparotomy

[0022] During the process of transporting and scaling the fish, when the fish is transported to the evisceration mechanism station, the evisceration mechanism is activated and an incision is formed by cutting along the midline of the fish's abdomen through the evisceration cutting part.

[0023] Step S4: Cleaning

[0024] When the fish carcass that has been gutted is transported to the evisceration mechanism station, the evisceration mechanism is activated and the internal organs are removed by rotating the evisceration digging and sweeping part.

[0025] Step S5: Material feeding

[0026] After the fish has been scaled, gutted, and cleaned, it continues to be transported to the end of the conveying unit and output from the discharge port of the frame.

[0027] Among them, steps S2, S3 and S4 are executed continuously on a single fish transport path, and the descaling action of step S2 is continuously performed during the execution of steps S3 and S4, realizing the integrated synchronous processing of the entire process of fish transport, descaling, gutting and eviscerating.

[0028] Beneficial Effects: This invention achieves integrated processing of scaling, gutting, and eviscerating throughout a single conveying process by setting up an integrated conveying and scaling mechanism that includes a conveying unit and a scaling unit, and arranging the evisceration and eviscerating mechanisms sequentially along the same conveying path. Compared with existing step-by-step processing methods, this invention not only eliminates the material transfer links between processes, avoiding collision damage and secondary contamination of fish during transfer, but also significantly improves the hygiene quality of processing. Furthermore, the conveying, scaling, gutting, and eviscerating processes share the same power source and conveying path, resulting in a highly integrated and compact equipment structure with a small footprint. The scaling action is integrated throughout the entire gutting and eviscerating process, maximizing the utilization of processing time and significantly increasing the output per unit time compared to step-by-step operations. Through the floating adaptive function of the conveying rollers and the independent feed adjustment of the scaling rollers, the equipment can automatically adapt to fish of different sizes without frequent shutdowns for adjustments, improving processing efficiency and adaptability.

[0031] Figure 3 for Figure 2 A magnified schematic diagram of the structure of region A in the middle. Detailed Implementation

[0032] The invention will now be further described with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, a single-path integrated fish processing device includes a frame 1 and a conveying and scaling integrated mechanism 2, a gutting mechanism 3, and a evisceration mechanism 4, all respectively mounted on the frame 1. The conveying and scaling integrated mechanism 2 includes a conveying unit 2a and a scaling unit 2b, the latter used to scrape fish scales during the conveying process of the fish by the conveying unit 2a. The gutting mechanism 3 and the evisceration mechanism 4 are sequentially arranged along the fish conveying path 100 of the conveying unit 2a, with the gutting cutting part 31 of the gutting mechanism 3 and the evisceration sweeping part 41 of the evisceration mechanism 4 extending from the bottom into the fish conveying space of the conveying unit 2a, so that the processes of cutting open the fish belly and removing the internal organs are completed sequentially along the same conveying path during the scaling process. The conveying and scaling integrated mechanism 2 is the core integrated unit of this invention, integrating the conveying unit 2a and the scaling unit 2b. The scaling unit 2b works as follows: throughout the entire process of the fish being conveyed forward by the conveying unit 2a, the scaling unit 2b continuously applies a scraping action to the surface of the fish, thereby achieving a parallel operation mode of conveying and descaling simultaneously. The evisceration cutting section 31 of the evisceration mechanism 3 and the evisceration sweeping section 41 of the evisceration mechanism 4 both adopt a layout that extends upwards from the bottom of the conveying unit 2a into the fish conveying space. The principle is that during the conveying process, the fish is held and positioned by the conveying unit 2a and naturally falls due to its own gravity. The cutting and sweeping sections extending from the bottom can directly act on the lowest area of ​​the fish's abdomen, ensuring that the evisceration action always proceeds along the midline of the abdomen, and that the evisceration action can penetrate deep into the bottom of the abdominal cavity. In summary, this invention constructs a processing method that integrates descaling, evisceration, and evisceration on a single fish conveying path 100. This eliminates the intermediate transfer links required for traditional step-by-step processing, avoids secondary contamination and mechanical damage to the fish during transfer, improves processing efficiency, and makes the equipment structure more compact, significantly reducing the overall length and floor space of the equipment.

[0034] like Figure 2As shown, the conveying unit 2a includes multiple sets of conveying rollers 21, the outer circumferential surface of which is usually covered with a rubber layer or knurled pattern to increase the coefficient of friction. The scaling unit 2b includes multiple sets of scaling rollers 22. The bristles of the scaling rollers 22 are made of nylon filaments with a certain degree of rigidity and wear resistance. In terms of mechanical layout, the axes of the conveying rollers 21 and the scaling rollers 22 are parallel, and the conveying rollers 21 and the scaling rollers 22 are arranged alternately on the fish conveying path 100. Therefore, during the conveying process, at least two conveying rollers 21 always support the weight of the fish and provide forward friction, while the scaling rollers 22 are located precisely in the gap between adjacent rollers. When the fish passes by, the rotating roller bristles can contact the surface of the fish without obstruction and scrape off the scales. This achieves a compact and optimized spatial layout of the conveying and scaling functions. That is, the fish will experience the scaling action of the rollers once for every distance of one roller spacing, so that the descaling action continues throughout the entire conveying stroke. The thoroughness of descaling is significantly better than that of traditional equipment that only performs centralized descaling at specific workstations.

[0035] like Figure 3 As shown, the integrated conveying and scraping mechanism 2 further includes a common frame 23 connecting the frame 1 and supporting the conveying unit 2a and the scraping unit 2b; the common frame 23 is provided with a roller mounting cavity 231 and a roller brush mounting cavity 232; a roller bearing seat 24 is provided in the roller mounting cavity 231, and the conveying roller 21 is rotatably mounted on the roller bearing seat 24; a roller brush bearing seat 25 is provided in the roller brush mounting cavity 232, and the scraping roller brush 22 is rotatably mounted on the roller brush bearing seat 25; the rotation of the conveying roller 21 and the rotation of the scraping roller brush 22 are independent of each other. Therefore, the rotation drive system of the conveying roller 21 and the rotation drive system of the scraping roller brush 22 are completely separated in terms of power source, and there is no mechanical transmission connection between them. At the same time, the rotation of each scraping roller brush 22 is independent of each other, that is, the start-up, shutdown or speed change of any scraping roller brush will not affect other roller brushes. The conveyor roller 21 needs to propel the fish forward at a stable linear speed, while the optimal scraping speed of the scraping brush 22 depends on factors such as fish species and scale adhesion; therefore, the two have different speed requirements. The independent operation of each brush allows for different speed settings for different parts of the fish. The conveyor speed and scraping speed can be independently optimized and adjusted without interference. When a brush requires maintenance due to foreign object entanglement or bristle wear, it can be stopped independently without affecting the entire production line, resulting in greater equipment operational flexibility.

[0036] Considering the individual differences in fish size, to enable the equipment to adaptively process fish of different sizes, a first guide rail 26 and a spring 27 are provided inside the roller mounting cavity 231. The roller bearing seat 24 is connected to a first slider 260 on the first guide rail 26, and the roller bearing seat 24 is connected to the inner wall of the roller mounting cavity 231 through the spring 27. The first guide rail 26 is fixedly installed on the inner wall of the roller mounting cavity 231 along a direction perpendicular to the fish conveying path 100, and the first slider 260 slides with the first guide rail 26. One end of the spring 27 is connected to the roller bearing seat 24, and the other end is connected to the side wall of the roller mounting cavity 231. The conveying roller 21 is floating on the common frame 23 by the elastic force provided by the spring 27, and the floating displacement direction of the conveying roller 21 is perpendicular to the fish conveying path 100. In its natural state, the spring 27 is in a compressed state, and the elastic force it generates pushes the roller bearing seat 24 and the conveying roller 21 mounted thereon toward the center of the fish conveying space. When a larger fish passes through, it presses against the conveyor roller 21, causing the roller bearing seat 24 to overcome the spring force and slide outward along the first guide rail 26, thereby widening the distance between the two rollers. The principle of this floating setting is to use the elastic deformation of the spring to absorb fluctuations in the size of the fish, so that the conveyor roller 21 always applies a flexible clamping force determined by the spring force to the fish, rather than a rigid fixed distance. This allows the equipment to automatically adapt to the passage of fish of different widths without the need for manual adjustment of the roller spacing. It ensures that small fish are effectively clamped and conveyed, while avoiding large fish from being stuck or excessively squeezed and damaged, thus achieving adaptive conveying and processing.

[0037] The scale-removing effect of the scraping roller brush 22 decreases due to bristle wear after long-term use. In this invention, a second guide rail 28 is provided in the roller brush mounting cavity 232, and a scale-removing feed cylinder 29 is provided on the common frame 23. The roller brush bearing seat 25 is connected to the second slider 280 on the second guide rail 28. The scale-removing feed cylinder 29 is connected to the roller brush bearing seat 25 and is used to push the corresponding scale-removing roller brush 22 toward the fish body to contact the fish scale surface. More specifically, the second guide rail 28 is fixedly installed in the direction toward the fish body conveying space, the bottom of the roller brush bearing seat 25 is fixedly connected to the second slider 280, and the second slider 280 slides with the second guide rail 28. The cylinder body of the scale-removing feed cylinder 29 is fixedly installed on the outer wall of the common frame 23, and its piston rod passes through the common frame 23 and is connected to the roller brush bearing seat 25. During equipment operation, the control system, based on a preset feeding program or real-time feedback on the descaling effect, controls the scraping feed cylinder 29 to push the roller brush bearing seat 25 along the second guide rail 28 towards the fish body. As the bristles gradually wear down, the outer diameter of the roller brush decreases. By pushing the entire roller brush closer to the fish body through the cylinder, the wear of the bristles can be compensated, ensuring that the bristle tips always contact the fish scale surface with appropriate pressure. This not only significantly extends the effective service life of the scraping roller brush 22 and reduces the frequency of bristle replacement, but also allows operators to adjust the cylinder air pressure according to different fish species (e.g., grass carp with tight scales, bass with loose scales), changing the pressure of the roller brush on the fish body, thus achieving adjustable descaling effect and improving adaptability.

[0038] like Figure 1 and Figure 3 As shown, the conveying unit 2a further includes a chain drive assembly 2.2 provided with conveying driving force by the conveying motor 2.1, and each of the conveying rollers 21 located on the same side of the fish conveying path 100 is connected through the chain drive assembly 2.2. Figure 3 As shown, the scaling unit 2b also includes a scaling motor 2.3, which is driven and connected to each of the scaling rollers 22 in a one-to-one manner. When the conveyor motor 2.1 starts, the chain drive assembly 2.2 drives all the conveyor rollers 21 to rotate synchronously in the same direction. The frictional force on the roller surface propels the fish body forward at a constant speed along the fish body conveying path 100. The scaling unit 2b adopts an independent drive design, allowing each roller to have an independent rotation speed. For example, the roller in the head area of ​​the fish body can use a higher rotation speed to deal with the dense head scales.

[0039] like Figure 2 As shown, the flank cutting part 31 of the flank cutting mechanism 3 is a flank cutting saw blade. The flank cutting saw blade is mounted on the frame 1 through the saw blade shaft 32, and the frame 1 is provided with a flank cutting motor 33 that drives and connects to the saw blade shaft 32.

[0040] like Figure 2As shown, the dirt removal mechanism 4 has a dirt removal scraping part 41 which is a dirt removal disc brush. The dirt removal disc brush is mounted on the frame 1 via a disc brush shaft 42, and the frame 1 is provided with a dirt removal motor 43 that drives and connects to the disc brush shaft 42.

[0041] A fish processing method using an integrated single-path fish transport processing device includes the following steps:

[0042] Step S1: Loading materials

[0043] The fish to be processed is placed at the starting end of the conveying unit 2a from the feed port 10 of the frame 1, so that the axis of the fish is parallel to the direction of the fish conveying path 100.

[0044] Step S2: Simultaneous conveying and descaling processing

[0045] The conveying unit 2a is started to drive the fish body to move along the fish body conveying path 100. At the same time, the scale scraping unit 2b is started to make the scale scraping roller 22 rotate and contact the surface of the fish body, so that the fish scales are scraped off synchronously during the fish body conveying process.

[0046] Step S3: Laparotomy

[0047] During the process of transporting and scaling the fish, when the fish is transported to the ventilating mechanism 3 station, the ventilating mechanism 3 is activated and an incision is formed along the midline of the fish belly through the ventilating cutting part 31.

[0048] Step S4: Cleaning

[0049] When the fish body that has been gutted is transported to the 4th station of the evisceration mechanism, the evisceration mechanism 4 is activated and the internal organs are removed by the rotating scraping section 41.

[0050] Step S5: Material feeding

[0051] After scaling, gutting, and cleaning, the fish is transported to the end of the conveying unit 2a and output from the discharge port of the frame 1.

[0052] Among them, steps S2, S3 and S4 are executed continuously on a single fish transport path 100, and the descaling action of step S2 is continuously performed during the execution of steps S3 and S4, realizing the integrated synchronous processing of the entire process of fish transport, descaling, gutting and eviscerating.

[0053] In summary, this invention achieves integrated processing of scaling, gutting, and eviscerating simultaneously in a single conveying process by setting up an integrated conveying and scaling mechanism that includes a conveying unit and a scaling unit, and arranging the evisceration and eviscerating mechanisms sequentially along the same conveying path. Compared with existing step-by-step processing methods, this invention not only eliminates the material transfer links between processes, avoiding collision damage and secondary contamination of fish during transfer, but also significantly improves the hygiene quality of processing. Furthermore, the conveying, scaling, gutting, and eviscerating processes share the same power source and conveying path, resulting in a highly integrated and compact equipment structure with a small footprint. The scaling action is integrated throughout the entire gutting and eviscerating process, maximizing the utilization of processing time and significantly increasing the output per unit time compared to step-by-step operations. Through the floating adaptive function of the conveying rollers and the independent feed adjustment of the scaling rollers, the equipment can automatically adapt to fish of different sizes without frequent shutdowns for adjustments, improving processing efficiency and adaptability.

[0054] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
