[0025] When the stepping motor 12 is controlled to be energized and rotate, driving the driving gear 24 to rotate. Under the meshing action between the driving gear 24 and the transmission gear 25, the water delivery cylinder 17 can be driven to rotate relative to the first piston rod 18. Under the threaded cooperation between the first piston rod 18 and the water delivery cylinder 17, the first piston rod 18 can be driven to move relative to the water delivery cylinder 17, so as to input the water in the water delivery cylinder 17 into the output hole and finally enter the water tank 7 through the opened electromagnetic valve 10, realizing the cleaning work of the output head 11. And when the transmission turntable rotates by a preset angle, that is, when the feeding cylinder 20 reaches the preset position, the feeding trigger assembly can be controlled to work, so that the valve structure can be controlled to work, making the feeding cylinder 20 at the corresponding position communicate with the output head 11. At this time, under the elastic restoring force between the second piston rod 22 and the feeding cylinder 20, the second piston rod 22 can be driven to move relative to the feeding cylinder 20, so as to input the additive in the feeding cylinder 20 into the output head 11 and finally discharge it into the liquid adding head 9, realizing the automatic liquid adding work.

[0029] It should be added that the trigger member includes a conductive arm 29 and a plurality of conductive strips 30. The plurality of conductive strips 30 are annularly arranged on the collar 28. The conductive arm 29 is arranged on the fixed seat disk. The conductive strips 30 are located on the moving path of the conductive arm 29.

[0030] During the process of the stepping motor 12 driving the driving gear 24 to rotate, it can drive the transmission gear 25 to rotate synchronously, and then drive the collar 28 to rotate relative to the fixed disk 27, so that the conductive strips 30 at different positions successively contact the conductive arm 29. Each time the conductive arm 29 contacts the conductive strip 30, it can control the electromagnets 16 at the corresponding positions to repel each other when energized, so that the adapter 14 opens, enabling the water delivery cylinder 17 and the output head 11 at the corresponding position to communicate and finally discharge from the liquid adding head 9, realizing the liquid adding work of the additive. When the conductive arm 29 and the conductive strip 30 are separated, at this time the electromagnet 16 is powered off, and at the same time the solenoid valve 10 is controlled to open, so that the water flows into the output head 11 and finally enters the water tank 7, realizing the cleaning work of the output head 11.

[0031] Please refer to Figures 1-8 , as another preferred embodiment of this application, the conductive arm 29 is movably arranged on the fixed disk 27 and is elastically connected between the two. The material feeding trigger assembly further includes a power-off unit. The power-off unit is arranged on the collar 28 and on one side of the conductive strip 30 for controlling the disconnection and connection time of the conductive arm 29 and the conductive strip 30.

[0032] Non-restrictive, the power-off unit includes a contact block 33, a slot 31, a guide rail 32 and a block 35, the ring 28 is located on one side of the conductive strip 30 and is provided with a guide rail 32, the slots 31 are in a plurality and are equidistantly arranged on one side of the guide rail 32, the contact block 33 is movably arranged in the guide rail 32 and the two are elastically connected, the block 35 is movably arranged on the contact block 33 and the two are elastically connected, the slot 31 is located on the moving path of the block 35 and the two are adapted to each other, the contact block 33 is provided with an inclined surface 34, and the inclined surface 34 is arranged on the moving path of the conductive arm 29.

[0033] It should be noted that the present embodiment is not limited to the above-mentioned abutment block 33 and conductive arm 29 abutting against each other to adjust the position of conductive arm 29 , and a linear motor or electric cylinder may be used instead, which are not listed here one by one.

[0034] In actual application, the position of the interference block 33 in the guide rail 32 is adjusted by adjusting the block 35 and the card slots 31 at different positions according to the required amount of conger eel liquid processed each time, and when the conductive arm 29 and the inclined surface 34 on the interference block 33 meet and conflict, the conductive arm 29 can be driven to move relative to the fixed disk 27, so that the conductive arm 29 and the conductive strip 30 are separated, and the electromagnet 16 is powered off, thereby adjusting the feeding time of different additives and indirectly adjusting the proportion of the additives.

[0035] How this application works: By placing the entire device beside the conger eel liquid processing device and rotating the screw sleeve 3, under the screw-thread engagement between the threaded rod 4 and the screw sleeve 3, the lifting table 1 can be driven to move up and down relative to the support table 2, thus facilitating the entire device to match conger eel liquid processing devices of different sizes. And by controlling the stepping motor 12 to be energized and rotate through the control console 5, the driving gear 24 can be driven to rotate. Under the meshing action between the driving gear 24 and the transmission gear 25, the transmission gear 25 can be driven to rotate, and the water delivery cylinder 17 can be driven to rotate relative to the first piston rod 18. Under the screw-thread engagement between the first piston rod 18 and the water delivery cylinder 17, the first piston rod 18 can be driven to move relative to the water delivery cylinder 17, so that the water in the water delivery cylinder 17 is input into the output hole and finally enters the water tank 7 through opening the solenoid valve 10, realizing the cleaning work of the output head 11. This enables the conductive strips 30 at different positions to successively contact the conductive arm 29. Each time the conductive arm 29 contacts the conductive strip 30, the electromagnet 16 at the corresponding position can be controlled to be energized and repel, so that the mating head 14 is opened, enabling the water delivery cylinder 17 and the output head 11 at the corresponding position to communicate and finally discharge from the liquid adding head 9, realizing the liquid adding work of the additive. When the conductive arm 29 and the conductive strip 30 are separated, at this time the electromagnet 16 is de-energized, and at the same time the solenoid valve 10 is controlled to open, so that water flows into the output head 11 and finally enters the water tank 7, realizing the cleaning work of the output head 11. By adjusting the cooperation between the clamping block 35 and the clamping grooves 31 at different positions according to the required amount of each conger eel liquid processing, the adjustment work of the position of the abutting block 33 in the guide rail 32 can be realized. And when the inclined surface 34 on the conductive arm 29 and the abutting block 33 meet and abut, the conductive arm 29 can be driven to move relative to the fixed disk 27, so that the conductive arm 29 and the conductive strip 30 are separated, realizing the de-energization work of the electromagnet 16, thereby realizing the adjustment of the feeding time of different additives and indirectly realizing the adjustment work of the proportion of the additive.
