Description

Technical Field

[0001] The utility model relates to the technical field of fish processing equipment, in particular to a handheld fish black film removing device. Background Art

[0002] The mesenchyme of fish is often black in color. It protects and lubricates the fish's internal organs, reducing friction and preventing injury. However, the mesenchyme tends to accumulate fat-soluble pollutants and has a fishy smell. Therefore, it is typically removed before slaughtering to improve the flavor and quality of the fish.

[0003] In the prior art, the black film inside the fish belly is mostly removed by hand-tearing. However, this method is not only difficult to operate and has low removal efficiency, but also difficult to completely remove. Therefore, when processing batches of fish, most workers usually scrub the fish fillets with a hand-held scraper or brush and then rinse them in water.

[0004] However, scraping the fish film with a scraper can easily damage the fish glue, resulting in fish meat defects and reduced customer satisfaction. In addition, scrapers or brushes are not effective in removing the fish film in corners or folds, often leaving some of the film behind, affecting the taste of the fish when eaten.

[0005] In addition, the equipment for batch removal of black film from fish in the existing technology all cuts the fish body and then uses a brush to scrub the sliced ​​fish body to remove the black film. This method is suitable for batch fish product processing, but is not suitable for slaughtering retail fish with different needs. Slaughter must be carried out according to customer needs.

[0059] This embodiment relates to a handheld device for removing fish film. The device comprises a drive unit 1, a connecting shaft 2 disposed at the power output end of the drive unit 1, and a first scraper unit 3 slidably connected to the connecting shaft 2 along the axial direction. The drive unit 1 drives the first scraper unit 3 to rotate to remove the film from the fish. A lower clutch body 301 is also disposed within the first scraper unit 3, and a receiving cavity 302 is formed within the first scraper unit 3.

[0060] Furthermore, a second scraper unit 4 is pivotally connected above the connecting shaft 2 and disposed within the accommodating chamber 302. An upper clutch unit 401 is disposed at the lower end of the second scraper unit 4, which engages with the lower clutch unit 301. When the lower clutch unit 301 is driven into engagement with the upper clutch unit 401, the driving unit 1 causes the first scraper unit 3 and the second scraper unit 4 to rotate simultaneously.

[0061] The handheld fish film removal device of this embodiment is provided with a driving unit 1 for driving the first scraping unit 3 to rotate and remove the film from the fish. After the lower clutch body 301 is driven upward to engage with the upper clutch body 401, the second scraping unit 4 rotates simultaneously with the first scraping unit 3. The first scraping unit 3 is used to scrape the film from fish that have been cut into slices. The rotation of the first scraping unit 3 is suitable for removing large areas of film. When removing uncut fish, the first scraping unit 3 is not easy to scrape the corners of the fish belly after the internal organs are removed. The second scraping unit 4 can be rotated to scrape the film from the corners or wrinkles. This ensures a more comprehensive black film removal effect and avoids the use of a scraper or brush to damage the fish glue, thereby improving customer satisfaction.

[0062] Based on the above overall introduction, an exemplary structure of the handheld fish black film removal device of this embodiment is as follows: Figures 1 to 5 As shown, the driving part 1 adopts a driving motor, the first scraping part 3 is located on the outside of the second scraping part 4, and the second scraping part 4 partially protrudes from the first scraping part 3. The upper clutch body 401 and the lower clutch body 301 are engaged or disengaged to adapt to the use of removing black film from different fish bodies.

[0063] As a preferred embodiment, Figures 3 to 5 As shown, one end of the connecting shaft 2 is keyed to the output shaft of the drive unit 1, and the other end is provided with a plurality of first circular arc grooves 201 arranged along its axial direction. A sliding sleeve 5 is sleeved on the outer side of the other end of the connecting shaft 2, and the sliding sleeve 5 is provided with a plurality of second circular arc grooves 501 extending therethrough along its axial direction. The first circular arc grooves 201 and the second circular arc grooves 501 are arranged in a one-to-one correspondence, and a pin 6 is provided between the connecting shaft 2 and the sliding sleeve 5. The pin 6 is located in the circular space formed by the first circular arc grooves 201 and the second circular arc grooves 501, and the sliding sleeve 5 is driven to slide along the connecting shaft 2, thereby being fixedly connected to the lower clutch body 301.

[0064] like Figures 4 to 6 As shown, the sliding sleeve 5 is a circular ring 3031, which is mounted on the outside of the connecting shaft 2. The first arc groove 201 and the second arc groove 501 are both semicircular grooves with equal diameters. The diameter of the pin 6 is slightly smaller than the circular space. In this embodiment, the gap between the diameter of the pin 6 and the circular space is between 0.01 and 0.05 mm, which facilitates the sliding of the sliding sleeve 5.

[0065] In this embodiment, by providing a sliding sleeve 5 and a pin shaft 6 between the sliding sleeve 5 and the connecting shaft 2, it is not only convenient for the sliding between the sliding sleeve 5 and the connecting shaft 2, but also convenient for the sliding sleeve 5 to pivot when the connecting shaft 2 pivots, thereby ensuring the scraping effect of the first scraping part 3.

[0066] Furthermore, if Figures 1 to 5As shown, the handheld fish black film removal device also includes a mounting portion 7, a cavity 701 is formed in the mounting portion 7, and the driving portion 1 is arranged in the cavity 701.

When the trigger portion 8 is driven up and down, the sleeve 303 reciprocates axially along the connecting shaft 2, causing the lower clutch body 301 to be disengaged or engaged with the upper clutch body 401.

[0071] like Figures 1 to 5 As shown, the triggering portion 8 is a shifting block disposed outside the mounting portion 7. A connecting block 12 is disposed between the connecting rod and the shifting block. The mounting portion 7 is provided with a slide groove 704 for the connecting block 12 to slide up and down. A through groove 702 is provided along the axial direction of the mounting portion 7, and the connecting rod is partially inserted into the slide groove 704. The connecting block 12 is fixedly connected to the connecting rod with a bolt.

[0072] And, as Figure 5 As shown, the stopper 10 is formed with a U-shaped groove opening toward the circular ring 3031. The width of the U-shaped groove matches the thickness of the circular ring 3031. When the triggering portion 8 is driven upward by the operator, the lower clutch body 301 engages with the upper clutch body 401. At this time, the driving portion 1 can drive the first scraping portion 3 and the second scraping portion 4 to rotate simultaneously, thereby removing the black film on the belly and corners of the fish body, improving the removal effect of the black film. In addition, the second scraping portion 4 is suitable for removing the black film in small gaps or folds, making the black film removal more clean and comprehensive.

[0073] like Figures 4 and 5 As shown, a housing cavity 302 is formed within the sleeve 303, and an upper clutch body 401 is disposed within the housing cavity 302. A support shaft 13 is also disposed within the housing cavity 302, and the support shaft 13 is fixedly connected to the connecting shaft 2. The support shaft 13 is connected below the second scraping portion 4, and the upper clutch body 401 is sleeved around the support shaft 13 and the outside of the second scraping portion 4. The upper clutch body 401 is pivotally connected to the support shaft 13.

[0074] Still Figures 4 and 5 As shown, the support shaft 13 has an I-shaped longitudinal section and a rotating body structure.

The lower end of the support shaft 13 is disposed within the stepped hole and is fixedly connected to the connecting shaft 2. The upper end of the support shaft 13 is disposed within the inner hole of the upper clutch body 401, and a self-lubricating bearing is sleeved on the outer side of the support shaft 13. The self-lubricating bearing is disposed within the upper clutch body 401.

[0075] Preferably, still as Figures 4 and 5 As shown, the second scraping part 4 includes a rotating shaft 402 connected to the inner ring of the upper clutch body 401, and a second brush layer 403 provided on the outer side of the rotating shaft 402. The second brush layer 403 is made of nylon brush filaments.

[0076] In addition, if Figures 4 and 5 As shown, a first water conduit 1301 is formed along the support shaft 13, and a second water conduit 4021 is formed within the rotating shaft 402. A connector 11 is radially disposed along the support shaft 13. This connector 11 is connected to an external water pump via a flexible hose and is also connected to the first water conduit 1301. The rotating shaft 402 is provided with a plurality of first water outlet holes 4022 arranged radially thereon.

[0077] Combine Figures 1 to 2 As shown, both the sleeve 303 and the brush cover 304 are provided with a second water outlet hole 3032 extending through the thickness of both. The first water outlet hole 4022 and the second water outlet hole 3032 are circular holes. To achieve a better spraying effect, spray nozzles can be installed on the first water outlet hole 4022 and the second water outlet hole 3032, so that the first scraping part 3 and the second scraping part 4 can rinse the peeled black film during the black film removal process, achieving a better cleaning effect.

[0078] The handheld fish black film removal device of this embodiment drives the lower clutch body 301 to move upward and engage or disengage with the upper clutch body 401. Through the combination or separate action of the second scraping part 4 and the first scraping part 3, it is used for scraping off the black film of uncut fish bodies and sliced ​​fish bodies, which can ensure that the black film scraping effect is more comprehensive, and can also avoid using a scraper or brush to destroy the fish glue, thereby improving customer satisfaction.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
