Description

Technical Field

[0001] This utility model relates to the field of food processing machinery technology, and more specifically, to a fish descaling machine. Background Technology

[0002] Fish processing is a crucial part of the food industry, and descaling, as a key pretreatment step, directly impacts the efficiency and quality of subsequent processing. Traditional manual descaling methods suffer from high labor intensity, low efficiency, and difficulty in controlling hygiene, prompting the development of mechanical descaling equipment. However, existing fish descaling machines, such as the friction descaling device disclosed in CN107041416A, consist of a drive motor, a lifting cylinder, a descaling barrel, and a descaling roller. The lifting cylinder movably mounts the descaling barrel via a sliding rod, and the drive motor is positioned above the descaling barrel. A descaling roller is installed inside the descaling barrel, with its upper end passing through the barrel and connected to the drive motor, while its lower end is intermittently sealed to the descaling barrel. Although the above-mentioned device has achieved continuous and mechanized fish descaling production, it still has technical defects in practical applications: due to the use of fixed descaling rollers or brushes, it is difficult to adapt to the differences in scale size and distribution of different fish species (such as crucian carp, grass carp, ribbonfish, etc.), which can easily lead to incomplete descaling or damage to the surface of the fish. Utility Model Content

[0003] Therefore, in order to solve the problem that existing descaling devices are difficult to adapt to the scale sizes of different fish species, this utility model provides a fish descaling machine, the specific technical solution of which is as follows:

[0004] A fish descaling machine includes a processing table and a descaling mechanism. A processing cover is installed on the processing table, and multiple feeding rollers are spaced apart inside the processing cover. Several water guide grooves are formed on the outer surface of the feeding rollers. The descaling mechanism includes a pipe frame and two nozzle assemblies. The pipe frame is inserted into the inner wall of the processing cover and is positioned between two adjacent feeding rollers. An opening for fish to pass through is formed on the pipe frame. The two nozzle assemblies are arranged vertically on the pipe frame and face the opening respectively. Each nozzle assembly includes multiple nozzles, and a buffer net for buffering water flow is provided at the end of each nozzle that communicates with the pipe frame.

[0005] The aforementioned fish descaling machine features a processing hood that effectively prevents scales, mucus, and moisture from splashing onto operators during the descaling process, thus avoiding scratches or contamination. A water guide channel directly increases the contact area between the feeding roller and the fish, providing stronger grip, especially in slippery environments, reducing slippage. It also creates a directional drainage path, preventing liquid accumulation on the feeding cylinder surface from causing secondary contamination or slippage. The dual-nozzle assembly, with its coordinated design of alternating vertical and horizontal water flow, adapts to the different scale sizes and distributions of various fish species, significantly improving descaling efficiency, reducing fish damage, and optimizing operational hygiene. A buffer net enhances the structural stability of the nozzles.

[0006] Furthermore, the fish descaling machine also includes a feeding mechanism disposed on one side of the processing cover. The feeding mechanism includes a limiting roller and a supporting roller. The limiting roller is slidably disposed on the processing table and can be raised and lowered relative to the processing table. An inlet and outlet gap is formed between the limiting roller and the supporting roller to allow fish to pass through.

[0007] Furthermore, the feeding mechanism also includes a fixed seat, a lifting seat, and a mounting frame mounted on the processing table. The mounting frame is provided with a guide rail, the fixed seat is threaded onto the bottom of the mounting frame, the lifting seat is slidably mounted on the guide rail, the supporting roller is mounted on the fixed seat, and the limiting roller is mounted on the lifting seat.

[0008] Furthermore, the feeding mechanism also includes a drive device fixed to the top of the mounting frame, the drive device being connected to the lifting seat and used to control the sliding state of the lifting seat.

[0009] Furthermore, the fish descaling machine also includes a discharge mechanism located on the other side of the processing hood, the structure of which is the same as that of the feeding mechanism.

[0010] Furthermore, the processing cover has an inlet and an outlet on its two sides, respectively.

[0011] Furthermore, the water guide grooves are regularly distributed in a ring or spiral shape on the outer surface of the feeding roller, and all the water guide grooves on the same ring or spiral line are interconnected. The side of the water guide groove is provided with a water guiding slope, and the outer surface of the feeding roller is also provided with a spacer band along the axial direction. The depth of the water guide groove gradually decreases at the end near the spacer band.

[0012] Furthermore, there are multiple descaling mechanisms, which are spaced apart inside the processing cover. Each pipe frame is connected to a water inlet pipe, one end of which passes through the processing cover and extends to the outside of the processing cover.

[0013] Furthermore, the nozzle is provided with a water spray channel for guiding the water flow. The water spray channel includes two coaxially connected inlet and outlet channels. In the direction perpendicular to the water flow, the cross-section of the outlet channel is smaller than that of the inlet channel. A reinforcing column is provided between the inlet channel and the outlet channel. The reinforcing column has a columnar structure and a guide channel is provided inside the reinforcing column. The cross-sectional area of ​​the guide channel gradually decreases along the direction close to the outlet channel.

[0014] Furthermore, the open edge of the guide channel near the outlet channel coincides with the opening edge of the outlet channel, and the open edge of the guide channel away from the outlet channel is attached to the inner wall of the outlet channel. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit its scope of protection.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0027] like Figures 1-5 As shown, a fish descaling machine according to one embodiment of the present invention includes a processing table 1 and a descaling mechanism; a processing cover 2 is installed on the processing table 1, and multiple feeding rollers 3 are spaced apart inside the processing cover 2, and a number of water guide grooves 31 are opened on the outer surface of the feeding rollers 3; the descaling mechanism includes a pipe frame 4 and two nozzle assemblies, the pipe frame 4 is inserted into the inner wall of the processing cover 2 and is set between two adjacent feeding rollers 3, and an opening for fish to pass through is opened on the pipe frame 4, and the two nozzle assemblies are arranged vertically on the pipe frame 4 and face the opening respectively, and the nozzle assembly includes multiple nozzles 5, and a buffer net 51 for buffering water flow is provided on the end of the nozzle 5 that communicates with the pipe frame 4.

[0028] The aforementioned fish descaling machine, by incorporating a processing hood 2, effectively prevents fish scales, mucus, and moisture from splashing onto operators during the descaling process, thus avoiding scratches or contamination. The water guide trough 31 directly increases the contact area between the feeding roller 3 and the fish, providing stronger grip, especially in slippery environments, reducing slippage. Simultaneously, it creates a directional drainage path, preventing liquid accumulation on the surface of the feeding cylinder from causing secondary contamination or slippage. The two nozzle assemblies, employing a coordinated design of intersecting water flow, can adapt to the different scale sizes and distributions of various fish species, significantly improving descaling efficiency, reducing fish damage, and optimizing operational hygiene. The inclusion of a buffer net 51 enhances the structural stability of the nozzle 5.

[0029] Preferably, nozzle 5 is made of stainless steel. This increases the strength of nozzle 5 and allows it to adapt to water flow of varying intensities.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the fish descaling machine further includes a feeding mechanism 6 disposed on one side of the processing hood 2. The feeding mechanism 6 includes a limiting roller 61 and a supporting roller 62. The limiting roller 61 is slidably disposed on the processing table 1 and can be raised and lowered relative to the processing table 1. An inlet and outlet gap is formed between the limiting roller 61 and the supporting roller 62 for fish to pass through. The size of the inlet and outlet gap can be adjusted by adjusting the height of the limiting roller 61, thereby facilitating adaptation to fish of different sizes and improving applicability and stability.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the feeding mechanism 6 further includes a fixed seat, a lifting seat, and a mounting frame mounted on the processing table 1. The mounting frame is provided with a guide rail. The fixed seat is threaded onto the bottom of the mounting frame. The lifting seat is slidably mounted on the guide rail. The support roller 62 is mounted on the fixed seat, and the limiting roller 61 is mounted on the lifting seat. The sliding of the lifting seat on the guide rail enables it to drive the limiting roller 61 to move up and down, thereby allowing the limiting roller 61 to reciprocate and adjust the distance between itself and the support roller 62, thus adjusting the size of the feed gap.

[0032] Specifically, the guide rail is set in a vertical direction.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the feeding mechanism 6 further includes a drive device 63 fixed to the top of the mounting frame. The drive device 63 is connected to the lifting seat and is used to control the sliding state of the lifting seat.

[0034] like Figure 1 and Figure 2As shown, in one embodiment, the fish descaling machine also includes a discharge mechanism 7 disposed on the other side of the processing cover 2, and the structure of the discharge mechanism 7 is the same as that of the feeding mechanism 6.

[0035] In one embodiment, the processing cover 2 has an inlet and an outlet on each side, facilitating the loading and unloading of fish.

[0036] like Figure 3 As shown, in one embodiment, the water guide grooves 31 are regularly distributed in a ring or spiral shape on the outer surface of the feeding roller 3, and all the water guide grooves 31 on the same ring or spiral line are interconnected. Water guide slopes 32 are provided on the sides of the water guide grooves 31, and spacer bands 33 are also provided along the axial direction on the outer surface of the feeding roller 3. The depth of the water guide grooves 31 gradually decreases at the end near the spacer bands 33. When the feeding cylinder rotates, the continuous oblique ridges in the ring or spiral shape form a dynamic, interlaced frictional force with the fish. Compared to the unidirectional resistance of straight grooves, this can more effectively prevent material slippage or deviation. Furthermore, the smooth transition edges of the ring or spiral shape (in contrast to sharp teeth) also help reduce scratches on the fish's skin.

[0037] like Figure 2 and Figure 4 As shown, in one embodiment, there are multiple descaling mechanisms, which are spaced apart inside the processing cover 2. Each pipe frame 4 is connected to a water inlet pipe 41, one end of which passes through the processing cover 2 and extends to the outside of the processing cover 2. The multiple descaling mechanisms can be activated sequentially at intervals, which can effectively reduce energy consumption and water consumption while ensuring the descaling effect.

[0038] like Figure 5 and Figure 6 As shown, in one embodiment, a water jet channel 52 for guiding water flow is provided through the nozzle 5. The water jet channel 52 includes two coaxially connected inlet channel 521 and outlet channel 522. In the direction perpendicular to the water flow, the cross-section of the outlet channel 522 is smaller than that of the inlet channel 521. A reinforcing column 53 is provided between the inlet channel 521 and the outlet channel 522. The reinforcing column 53 has a columnar structure and a guide channel 54 is provided through it. The cross-sectional area of ​​the guide channel 54 gradually decreases along the direction closer to the outlet channel 522. By utilizing the diameter difference between the outlet channel 522 and the inlet channel 521, the flow velocity and pressure of the water flow increase when it enters the outlet channel 522 from the inlet channel 521, ultimately giving the water jet from the nozzle 5 sufficient flow velocity and impact force.

[0039] Preferably, the reinforcing column 53 is a silicon nitride ceramic sheet.

[0040] like Figure 6As shown, in one embodiment, the open edge of the guide channel 54 near the outlet channel 522 coincides with the opening edge of the outlet channel 522, and the open edge of the guide channel 54 away from the outlet channel 522 is attached to the inner wall of the outlet channel 522.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
