[0025] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.

[0026] See also Figure 1-Figure 4 A multi-dye feeding auxiliary metering mechanism is mainly composed of a metering tank 1, a material pipe 2, a control valve A 3, a piston 4, a connecting pipe 5, a control valve B 13, a bracket 6, an exhaust pipe 7, a control valve C 8, a magnet 9, etc.

[0027] The metering tank 1 is a container without a bottom surface. The material pipe 2 is installed at the top of the metering tank 1 for introducing dyes. The A control valve 3 controls the on and off of the material pipe 2. The piston 4 is installed inside the metering tank 1 and can slide. It forms a storage space with the upper space of the metering tank 1. The support 6 drives the piston 4 to slide up and down in the metering tank 1 to adjust the capacity of the storage space. The outer side of the piston 4 is provided with a sealing ring, so that when the piston 4 slides in the metering tank 1, it is sealed by the sealing ring to prevent dye leakage and metering errors.

[0028] The bracket 6 includes an outer ring 61 and an inner ring 62 that slide inside and outside the metering tank 1. The bottoms of the outer ring 61 and the inner ring 62 are connected by a plurality of U-shaped frames 63. The piston 4 is detachably connected to the thread inside the inner ring 62 through the threaded sleeve 41 at its bottom. Two sets of symmetrically distributed slide grooves 10 are provided on the outside of the metering tank 1. The protrusions 11 on the inner side of the outer ring 61 slide in the slide grooves 10 to achieve the up and down movement of the bracket 6.

[0029] The top section of the piston 4 is arc-shaped, and the connecting pipe 5 is connected to the arc-shaped interface at the bottom of the piston 4, which facilitates the introduction of dye into the connecting pipe 5. The connecting pipe 5 is installed with a B control valve 13. The exhaust pipe 7 is installed at the top of the metering tank 1, and the C control valve 8 controls the on-off of the exhaust pipe 7. The sensor on the exhaust pipe 7 is used to detect dye overflow. When the sensor detects that the dye enters the exhaust pipe 7, the A control valve 3 closes the material pipe 2.

[0030] Two symmetrically distributed magnets 9 on the side of the metering tank 1 are adsorbed on the metering tank 1, and the ratchet teeth inside thereof are docked with the ratchet bars 12 in the slide groove 10 to prevent the magnets 9 from sliding off the slide groove 10 and support the bracket 6 at the same time.

[0031] The inner side surface of the magnet 9 is an arc surface, and the inner side surface of the magnet 9 is attached to the outer side surface of the measuring tank 1, and the measuring tank 1 is made of iron-containing metal material.

[0032] First, adjust the position of magnet 9 so that magnet 9 supports bracket 6, and adjust the position of piston 4 by the position of bracket 6, so as to adjust the capacity of the storage space of metering tank 1. When feeding, B control valve 13 is closed, A control valve 3 and C control valve 8 are opened, so that the dye enters the storage space of metering tank 1, and the air is discharged through exhaust pipe 7. When the sensor on exhaust pipe 7 detects that the dye enters exhaust pipe 7, A control valve 3 closes material pipe 2. When discharging, open B control valve 13 on connecting pipe 5 to allow the dye to be discharged through connecting pipe 5, and exhaust pipe 7 is connected to the storage space of metering tank 1 to facilitate the discharge of the dye.
