[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Depend on Figure 1 to Figure 2 A fish peeling device is provided, comprising a frame 1, a feeding plate 2, a peeling roller 3, a pressure roller assembly, a fixed knife 5, a discharge plate 6 and a driving assembly.

[0028] The feeding plate 2 is installed inside the left side of the frame 1, and the peeling roller 3 is installed in the middle of the frame 1 and on the right side of the feeding plate 2; the pressure roller assembly is installed at the top of the frame 1, and the pressure roller assembly is located directly above the peeling roller 3. A certain distance is set between the pressure roller assembly and the peeling roller 3, and the pressure roller assembly is used to transport fish meat and fish fillets.

[0029] The driving assembly is installed on one side of the frame 1 and cooperates with the peeling roller 3 and the pressing roller assembly to drive the peeling roller 3 and the pressing roller assembly to rotate.

[0030] The fixed knife 5 is installed inside the frame 1 by bolts and is located on the right side of the peeling roller 3; the discharge plate 6 is installed inside the frame 1 and is located on the right side of the fixed knife 5; the blade of the fixed knife 5 separates the fish meat and the fish skin, and the separated fish meat is discharged from the discharge plate 6.

[0031] By turning the bolts and loosening the fixed knife 5, the position of the fixed knife 5 installed on the frame 1 can be adjusted so that the distance between the fixed knife 5 and the peeling roller 3 can be changed.

[0032] Depend on Figure 2 and Figure 6 It is shown that the fixed knife 5 is located between the peeling roller 3 and the pressure roller 4, and a fish meat end 51 and a fish skin end 52 are provided on one side of the fixed knife 5. When the fish meat contacts the blade of the fixed knife 5, the blade will separate the fish meat from the fish skin, and the fish meat and fish fillets are discharged from the surface of the fish meat end 51, and the fish skin slides off from the fish skin end 52.

[0033] The fish skin end 52 is arc-shaped. Since the skinning roller 3 is cylindrical, all the fish skin ends 52 are also arranged to be arc-shaped, and a spacing is arranged between the fish skin end and the skinning roller 3; the gap between the fixed knife 5 and the skinning roller 3 is adjustable. On the one hand, by adjusting the gap, the fish skin can be adhered to the fish meat as little as possible or not adhered to the fish meat, thereby reducing or avoiding the loss of the fish meat; on the other hand, by adjusting the gap, the thickness of the fish skin of different fish species can be adapted to meet the processing requirements of various fish species.

[0034] The discharging plate 6 is located on the right side of the fixed knife 5, and the discharging plate 6 is tilted downward to facilitate the fish meat to slide down.

[0035] The beneficial effects obtained by the frame 1, the feeding plate 2, the peeling roller 3, the pressure roller assembly, the fixed knife 5, the discharge plate 6 and the driving assembly are as follows: the fish peeling device can meet the peeling requirements of different fish and fish fillets of different sizes, the peeling is thorough, the peeling rate reaches more than 95%, the fish meat loss rate is small, and almost lossless peeling can be achieved. The device can be used on the assembly line equipment or stand-alone equipment for the primary processing of fish.

[0036] Depend on Figure 1 to Figure 2 It is shown that the right side of the feed plate 2 is located between the peeling roller 3 and the pressure roller assembly, and the feed plate 2 is slightly lower than the top of the peeling roller 3.

[0037] Depend on Figures 2 to 4 It is shown that a plurality of saw teeth are evenly arranged on the surface circumference of the peeling roller 3, and adjacent saw teeth are asymmetrically arranged on the left and right. The inclination of the saw teeth is larger when working, and the inclination of the saw teeth is gentler when not working, forming a structure similar to a barb. This structural form can provide better friction for the fish skin, so that the peeling roller 3 can better grasp the fish skin layer, prevent slipping, tearing, etc., and significantly improve the peeling efficiency and peeling rate.

[0038] Depend on Figure 1 , Figure 2 , Figure 5 It is shown that the nip roller assembly includes a nip roller 4 and a soft layer 7 .

[0039] A rotating shaft 41 is respectively provided on both sides of the pressing roller 4, and a bearing 42 is rotatably installed on the periphery of the rotating shaft 41. The periphery of the bearing 42 is installed on both sides of the frame 1. The pressing roller 4 presses the fish fillet from above, which can make the fish fillet better fed and discharged on the one hand, and on the other hand, it can make the fish fillet better fit with the peeling roller 3, thereby improving the peeling efficiency and peeling rate.

[0040] The pressing roller 4 not only enables the fish fillets to be fed in better, but also plays a role in throwing the peeled fish fillets.

[0041] The soft layer 7 is wrapped around the periphery of the pressing roller 4. The soft layer 7 has good elasticity and can solve the problem that the thinner areas of the fish fillets cannot be fully pressed due to the uneven thickness of the fish fillets. Through the contoured contact between the soft layer 7 and the fish fillets, each position of the fish fillets can be fully pressed, thereby better completing the peeling. At the same time, the flexible material will not damage the fish meat or cause fish meat loss during the process of pressing the fish fillets.

[0042] The nip roller 4 is composed of two sections for easy processing.

[0043] Depend on Figure 1 to Figure 2 It is given that the driving assembly includes a tensioning wheel, a chain, a motor wheel and a motor.

[0044] The tensioning wheel and the motor wheel are both rotatably installed on one side of the frame 1, and the tensioning wheel is installed on one side of the frame 1 by bolts, and the tensioning wheel can be adjusted in the installation position of the frame 1; the motor is installed on one side of the frame 1, and the output end of the motor is matched and connected with the motor wheel, and sprockets are installed on one side of the rotating shaft 41 and the peeling roller 3, and the tensioning wheel, the motor wheel and the two sprockets are connected by chains, one of the sprockets is meshed with the inner side of the chain, and the other sprocket is meshed with the outer side of the chain, and the two sprockets are driven to rotate together by the chain. Since the two sprockets are respectively installed on the inner side and the outer side of the chain, the two sprockets rotate in opposite directions.

[0045] The motor drives the motor wheel to rotate, and the tensioning wheel and the two sprockets rotate together through the chain.

[0046] The peeling roller 3 rotates clockwise, and the pressing roller 4 rotates counterclockwise. The rotation of the pressing roller 4 can make the fish fillets better fed and discharged.

[0047] Depend on Figure 1 to Figure 2 It is shown that an adjustment component cooperating with the nip roller 4 is also installed on one side of the frame 1 .

[0048] The adjustment assembly includes two fixings and two adjustment slots. The two adjustment slots are respectively opened on both sides of the frame 1. The bearing 42 is movably installed in the adjustment slot. The adjustment slot is opened vertically. The bearing 42 can be adjusted up and down in the adjustment slot to adjust the distance between the pressure roller 4 and the pressure roller 3. The bearing 42 can ensure that the rotation of the pressure roller 4 is not affected.

[0049] The fixing member 8 is a fixing block, which is sleeved on the outside of the rotating shaft 41 and is installed on one side of the frame 1 by bolts. The fixing block is used to fix the pinch roller 4 so that it is installed in the frame 1.

[0050] During adjustment, the bolt is turned to loosen the fixing block, and the fixing block, the pressure roller 4 and the bearing 42 are adjusted up and down together. After the adjustment is completed, the fixing block is re-fixed on one side of the frame 1.

[0051] When the utility model is used, the fish fillet is put into the feeding plate 2 with the fish skin facing downwards, and the fish skin is closely fitted to the skinning roller 3 under the pressing action of the pressing roller 4. The fish fillet moves backward under the joint action of the rotation of the skinning roller 3 and the pressing roller 4, that is, moves toward the discharge plate 6. When the fish fillet contacts the blade of the fixed knife 5, the blade separates the fish skin from the fish meat, so as to achieve the purpose of skinning. Finally, the skinned fish fillet is discharged from the discharge plate 6, and the fish skin slides down along the skinning roller 3.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
