SU682208A2 - Machine for skinning fish fillet - Google Patents

Description

The invention relates to the field of fish processing industry.

According to the main author, No. 556771, there is a known machine for skinning a fillet, which contains a loading table, a driving conveying drum, a rotary knife driven in rotation, and a pressing device. The conveying drum is concave and mounted relative to the annular knife so that it forms concentric to the cutting edge of the knife. The transporting drum is fixed on the swivel brackets with the possibility of changing the position relative to the knife ij.

A disadvantage of the known machine is the possibility of lateral displacement of the fillet during skinning, which reduces the quality of skinning, as well as low productivity, due to the inconvenience of loading and unloading the fillet.

The purpose of the invention is to improve the quality of skinning fillets.

This goal is achieved by the fact that in the proposed machine for skinning fish fillets the ring knife is set at an angle, preferably,. 10-15 to the vertical passing through the axis of the transporting drum, and has a flange with a wedge-shaped groove, and the clamping device consists of a transport located on the inside of the knife. With a flexible tape and freely running around spring-loaded rollers placed between its branches directly above the transporting drum, bending the tape along the fillet profile in cross section.

Dampers are installed on both sides of the knife with overlapping of the cutting zone.

Fig. 1 schematically shows the proposed machine for skinning fish fillets, general view; in fig. 2 shows a section A -A in FIG. fig.Z - clamping device, incision; figure 4 - section B - B in fig.Z; figure 5 - diagram of the machine in the two-handle version.

Machine for The skinning of the fish fillet contains a rotating transporting drum 1 having a concave surface, an annular knife 2, a pressing device, a loading 3 and a unloading 4 conveyors.

The ring knife 2 is set at an angle, mainly, 10-15 ° to

vertical axis passing through the axis of the drum 1, and has a flange 5 with a wedge-shaped groove and a cutting edge 6. The ring knife is mounted on three support rollers 7 mounted on the bracket 8, and is rotated from the electric motor 9 through the pulley 10 and the V-belt 11. Cutting the edge b of the knife is located con. centrically forming drum 1.

The clamping device consists of a conveyor located on the inside of the annular knife 2 with a flexible tape 12 having a corrugated working surface and a driving drum 13 and placed between the conveyor branches directly above the transporting drum 1 of the pressure rollers 14 mounted on the levers 15 with springs 16 with the possibility of free rolling in.

To eliminate the displacement of the fillet and skin from cutting forces and friction with the knife on both sides of the knife 2 with overlapping of the cutting zone, there are installed baffles 17 and 18 adjacent to the inner and outer surfaces of the knife. A transfer belt is installed between the drive drum. pad 20, and its surface is transferred from conveyor 3 to the concave surface of drum 1. The machine has a tray 21 for skins, drive 22 and frame 23,

In order to aggregate a fish skinning machine with a filleting machine without overloading arrangements, the machine is made up of a two-strand one-drive machine.

The machine works as follows.

The fillet of fish from the filleting machine is fed to the position of the skin down to the loading conveyor 3, which feeds it to the pressing device. Next, the transportation of the fillet and its simultaneous leveling are carried out between the belt of the conveyor 3 and the belt 12, which, starting from the transitional platform 20, continues to transport the fillet to the skin cutting section. As the fillet moves along the transitional platform 20, it smoothly compresses along its concave surface, and then tightly presses against the concave surface of drum 1, which is facilitated by spring-loaded freely rolling rollers 14. In this position, the fillet enters the annular knife 2 which concentrates layer of skin, the thickness corresponding to the adjustable gap between the knife 2 and the drum 1.

The skin being cut off passes between the visor 18 and the drum 1 and along the tray 21 is removed from the machine. A skin fillet passes between the belt 12 and the visor 17 to the discharge conveyor 4.

Setting the blade to a floor with an angle of predominantly 10–15 ° provides a reduction in the fillet lifting and bending on the cap 17,

For the reliability and simplicity of the knife drive in its flange 5, a groove for the V-belt 11 is made. Thus, the knife is a drive pulley of the V-belt transmission, thereby avoiding slippage and free space inside the knife for accommodating the clamping attachment, J

The proposed machine allows to improve the quality of skinning and has great performance.
