[0001] The utility model relates to the technical field of production of down filling machines, and more specifically to a down discharging mechanism of a down filling machine weighing box. Background Art

[0002] At present, all down filling machines need to be installed with an air amplifier. Its principle is based on the basic principle of fluid mechanics - the wall attachment effect. Only a small amount of compressed air is used as the power source to drive the surrounding air flow to form a high-pressure, high-speed airflow, so as to draw the down inside the weighing box to the down filling tube. The down filling tube fills the position where down needs to be filled. At present, only one air amplifier is generally installed between the down filling tube and the weighing box. The air extraction pressure is relatively small, and the phenomenon of insufficient down filling power often occurs. Utility Model Content

[0013] 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.

[0014] like Figures 1 to 3 It is a specific implementation of the utility model. A plurality of weighing boxes 1 are arranged inside the weighing box. Each weighing box 1 is provided with a down outlet 11. The structure thereof further includes two amplifiers 12, a down filling tube 13, a transfer joint 14, a pressure regulator 3, a pressure balancer 16 and a plurality of down outlet tubes 17. A main interface 2 is arranged at one end of the transfer joint 14. A plurality of branch interfaces 21 are arranged at the other end of the transfer joint 14. The number of the branch interfaces 21 is consistent with the number of the down outlet 11. A down outlet tube 17 is connected in parallel between the branch interfaces 21 and the down outlet 11. The branch interfaces 21 alternately supply down to the main interface 2 based on the down amount inside the weighing box 1.

[0015] One amplifier 12 , the pressure regulator 3 , the pressure balancer 16 and another amplifier 12 are sequentially connected between the main interface 2 and the down filling tube 13 via the down outlet tube 17 .

[0016] The process of weighing box down discharge is as follows: when down is discharged, the down inside one of the weighing boxes 1, under the action of two amplifiers 12, passes through the transfer joint 14, the pressure regulator 3, the pressure balancer 16 in sequence, and finally enters the down filling tube 13. The down filling tube 13 is aligned with the position where down needs to be filled for filling. During the down filling process, when the down inside this weighing box 1 is discharged, the down inside another weighing box 1 starts to discharge. According to the above process, different weighing boxes 1 alternately supply down to the main interface 2 to ensure the continuity of down filling.

[0017] In the utility model, two amplifiers 12 are arranged between the filling tube 13 and the main interface 2. The two amplifiers 12 are turned on at the same time to ensure the power for the down to flow from the weighing box 1 to the filling tube 13. The first amplifier 12 is used as the power for the down inside the weighing box 1 to enter the pressure regulator 3. During this stroke of the down, the pressure regulator 3 adjusts the gas pressure of this stroke, thereby ensuring that the down inside the weighing box 1 can smoothly enter the pressure regulator 3. Subsequently, under the action of the second amplifier 12, the down inside the pressure regulator 3 enters the filling tube 13 through the pressure balancer 16. During this stroke of the down, two situations will occur inside the filling tube 13:

[0018] The first type: the down inside the filling tube 13 flows smoothly, that is, the external filling position is relatively empty. At this time, in order to meet the need of the second amplifier 12 to blow air to the filling tube 13, the pressure balancer 16 needs to absorb air from the outside to balance the pressure inside this section of the stroke to ensure smooth filling.

[0019] The second type: the flow of down inside the filling tube 13 is relatively blocked, that is, the external filling position has begun to be gradually filled. At this time, the blowing of the second amplifier 12 to the filling tube 13 also begins to be blocked. In order to discharge the excess gas, the pressure balancer 16 discharges the excess gas to the outside, thereby balancing the pressure inside this section of the stroke and ensuring the smooth filling.

[0020] In the present utility model, as a preferred embodiment, the pressure regulator 3 comprises a bell mouth 31, an outer sleeve 32 and an inner sleeve 33 arranged on the velvet outlet pipe 17. The caliber of the outer sleeve 32 is consistent with the caliber of the end of the bell mouth 31. The interior of the outer sleeve 32 is hollow. A connecting pipe 4 is arranged inside the outer sleeve 32. The caliber of the connecting pipe 4 is consistent with the caliber of the velvet outlet pipe 17. One end of the connecting pipe 4 extends outside one end of the outer sleeve 32 and is connected to the velvet outlet pipe 17. The other end of the outer sleeve 32 is connected to the bell mouth 31. The other end of the connecting pipe 4 extends inside the outer sleeve 32 and is provided with an adjusting thread 41. The inner sleeve 33 is threadedly connected to the adjusting thread 41 and extends in a direction toward the bell mouth 31. An adjusting gap 42 is formed between the inner sleeve 33 and the inner wall of the bell mouth 31. The outer sleeve 32 is provided with an air outlet 43 protruding from the side wall of the outer sleeve 32.

[0021] In the utility model, by adjusting the position of the inner sleeve 33 on the adjusting thread 41, the adjusting gap 42 between the inner sleeve 33 and the inner wall of the bell mouth 31 is adjusted. The setting of the adjusting gap 42 can make the excess gas inside the pressure regulator 3 enter the space between the inner sleeve 33 and the outer sleeve 32, and then be discharged from the position of the air outlet 43, thereby realizing the pressure regulation between the weighing box 1 and the pressure regulator 3.

[0022] In the present invention, the pressure balancer 16 is a three-way pipe.

[0023] In the present utility model, as a preferred solution, two interfaces of the three-way pipe are respectively connected to the down outlet pipe 17, and the other interface of the three-way pipe is provided with a filter screen 5.

[0024] In the utility model, the three-way pipe has a simple structure and can meet the needs of the pressure balancer 16 to inhale or exhaust air when the filling tube 13 is blocked or unobstructed. Moreover, the setting of the filter screen 5 can prevent the internal down from flying out or absorb external impurities into the filling tube 13.

[0025] In the present invention, the sub-interface 21 supplies down to the main interface 2 alternately based on the down amount inside the weighing box 1, in two ways: Example 1

[0026] In this embodiment, when the distance between the down outlet 11 and the tapping port 21 is relatively short, the two amplifiers 12 can directly suck out the down inside the weighing box 1 . At this time, valves are provided on the tapping port 21 .

[0027] In this embodiment, the valve can be opened or closed according to the amount of down inside the weighing box 1, thereby controlling the opening or closing of the branch interface 21. For example, a solenoid valve or a pneumatic valve can be selected. When there is no down inside the corresponding weighing box 1, the corresponding valve is closed. When down is supplied to the outside from one of the weighing boxes 1, the corresponding valve is opened, thereby realizing alternating supply of down to the main interface 2. Example 2

[0028] In this embodiment, when the distance between the pile outlet 11 and the branch interface 21 is relatively long, the branch interface 21 is provided with a third amplifier.

[0029] In the utility model, the third amplifier can be turned on or off according to the amount of down inside the weighing box 1, so that the down inside the corresponding weighing box 1 can be drawn to the position of the branch interface 21, thereby realizing alternate supply of down to the main interface 2.
