Description

Technical Field

[0001] The utility model relates to the technical field of fish processing, in particular to a fully automatic fish descaling device. Background Art

[0002] In the processing of scaled fish, descaling is an indispensable preliminary step. Only by thoroughly removing the scales can the subsequent processing of fish meat, especially the production of fish fillets and fish steaks, be facilitated. At present, the descaling equipment on the market is generally designed so that the fish head enters the equipment first. The toothed drum inside the equipment rotates continuously, pushing the fish body forward slowly. At the same time, the rotating rakes inside descale the fish body. It is worth noting that these rakes scrape the scales from the tail of the fish to the head of the fish, which is consistent with the forward direction of the fish body.

[0003] However, this design has a significant drawback: when the fish body is conveyed too fast, the rake may not have time to completely scrape off the scales before the fish body is quickly transported away. This situation seriously limits the conveying speed of the fish body, which in turn affects the overall scraping efficiency. In order to ensure that the scales can be effectively scraped off, the contact speed between the rake and the fish scales must be higher than the conveying speed of the fish body. Unfortunately, too high a rake rotation speed may cause the fish meat to be scraped, resulting in a decrease in the quality of fish fillets and fish steaks.

[0004] In view of this, the current descaling technology still needs to be further improved. In order to solve the above problems, we designed a fully automatic fish descaling device. Compared with traditional equipment on the market, our device improves the descaling efficiency while maintaining the integrity of the fish meat. Utility Model Content

[0005] The utility model aims to provide a fully automatic fish descaling device to solve the problems described in the background technology.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A fully automatic fish descaling device comprises two driving mechanisms and two arc-shaped bottom plates arranged on a bracket, one bottom plate is higher than the other bottom plate, the upper surfaces of the two bottom plates are both provided with arc-shaped descaling scraping walls, the inner side walls of the descaling scraping walls are provided with arc-shaped concave surfaces, the arc-shaped concave surfaces are provided with a plurality of descaling protrusions, the ends of the descaling protrusions are rounded, a circular rotating drum is further provided on the inner side of the descaling scraping walls, a plurality of extruding protrusions and a push plate are further provided on the outer side wall of the rotating drum, the ends of the extruding protrusions are rounded, the ends of the push plates are further away from the center of the rotating drum than the ends of the extruding protrusions, and the ends of the push plates do not reach the center of the rotating drum. When reaching the scraping protrusion, the outer wall of the rotating drum and the inner wall of the descaling scraper wall are clamped with each other to form an arc-shaped descaling channel. The two rotating drums and the two descaling scrapers form two high and low distributed descaling channels. The descaling channel includes an inlet and an outlet. The ends of the scraping protrusions both point to the inlet of the descaling channel. The outlet of the higher descaling channel is connected to the inlet of the lower descaling channel through a flow track. The inlet of the higher descaling channel is connected to a feeding track, and the outlet of the lower descaling channel is connected to a discharging track. The two rotating drums are respectively connected to the two driving mechanisms one by one, and the driving mechanisms are used to drive the rotating drums to rotate.

[0008] When using the above scheme, the fish body is placed upright in the feeding track so that the fish tail enters the descaling channel first. When the fish body falls into the descaling channel, the push plate pushes the fish head to push the fish body toward the exit of the descaling channel, and the squeezing protrusion squeezes the fish body. The outer side of the fish body is pressed against the inner side wall of the descaling scraper wall. As the fish body continuously flows toward the exit of the descaling channel, the scale scraper protrusion continuously scrapes off the fish scales on the outer side of the fish body. The arc-shaped concave surface can fit the arc of the fish body itself, thereby improving the descaling coverage rate. The rounded end of the scale scraper protrusion can also prevent the scale scraper protrusion from damaging the fish meat.

[0009] After the fish body has finished circulating in the higher descaling channel, it enters the lower descaling channel through the circulation track to complete the descaling operation on the other side. After passing through the two descaling channels, the scales on both sides of the fish body are removed.

[0010] This device adopts the mode that the fish tail enters first, cooperates with the rotating drum and the scaling scraper, and abandons the rotating rake component originally used for descaling, so that the descaling rate of the fish body is only affected by the conveying speed of the rotating drum. By controlling the length and width of the descaling channel (in most cases, the fish processed in the fish factory are farmed fish, and their species, size (weight) are relatively stable. Therefore, for large-scale processing, the length and width of the descaling channel can be determined according to the processed fish species, and the width determines the degree of pressure on the fish body). Under suitable parameters, the fish can be descaled quickly by increasing the rotation speed of the rotating drum without damaging the fish meat.

[0011] A further technical solution is that the descaling outer wall in front of the entrance of the descaling channel gradually expands outward to form a gradually widening channel, the entrance of the gradually widening channel of the higher descaling channel is connected to the outlet of the feed track, and the entrance of the gradually widening channel of the lower descaling channel is connected to the outlet of the flow track.

[0012] When the above solution is used, by setting a gradually widened channel, the fish body can enter the descaling channel from the feeding track and the circulation track more smoothly.

[0013] A further technical solution is that the driving mechanism also includes a connecting frame fixedly connected to the inside of the drum, the driving mechanism also includes a rotating shaft arranged at the central axis of the drum, the top of the rotating shaft is fixedly connected to the connecting frame, the driving mechanism also includes a base, the bottom of the rotating shaft is rotatably installed in the base, the driving mechanism also includes a motor, a driving wheel is provided on the output shaft of the motor, and a driven wheel is fixedly sleeved on the rotating shaft, the driving wheel and the driven wheel are driven to rotate the rotating shaft.

[0014] When the above solution is used, the motor drives the driving wheel to rotate, the driving wheel drives the driven wheel to rotate, the driven wheel drives the rotating shaft to rotate, the rotating shaft drives the connecting frame to rotate, and the connecting frame drives the rotating drum to rotate.

[0015] A further technical solution is that the top of the descaling channel is also covered with a plurality of spaced baffles, and the bottoms of the baffles are fixedly connected to the top of the descaling scraper.

[0016] When the above solution is used, the blocking rod can be provided to effectively prevent the fish body from flying out during the descaling process.

[0017] A further technical solution is that it also includes a water spray head, which is arranged above the descaling channel, and the spraying direction of the water spray head is aimed at the arc-shaped concave surface of the descaling wall scraper.

[0018] When the above scheme is used, the fish scales on the descaling scraper wall can be effectively removed by setting a water spray head.

[0019] The beneficial effects of the utility model are:

[0020] 1. Efficient descaling: This solution makes the fish body stand up and let the fish tail enter the descaling channel first, and uses the push plate and descaling scraper to effectively remove the fish scales. This method abandons the traditional rotating rake parts, so the descaling speed is only affected by the conveying speed of the drum. Therefore, the descaling can be quickly carried out by increasing the rotation speed of the drum, thereby improving work efficiency.

[0021] 2. High descaling coverage: The arc-shaped concave design in the scheme can fit the curve of the fish body itself, ensuring that the fish scales can be scraped off more comprehensively, thereby improving the descaling coverage.

[0022] 3. Protect the quality of fish meat: The end of the scraping protrusion is designed to be smooth, which helps prevent damage to the fish meat during the descaling process and ensures the integrity and quality of the fish meat.

[0023] 4. Double-sided descaling design: The fish body first passes through a descaling channel to complete the descaling on one side, and then enters another lower descaling channel through a flow track to complete the descaling on the other side, ensuring that the scales on both sides of the fish body can be completely removed.
