Description

Technical Field

[0001] This utility model relates to the field of production technology of down filling machines, and more specifically, to a down outlet mechanism with flexibly switchable down filling weight. Background Technology

[0002] Amplifiers are required on all down filling machines. Their principle is based on the fundamental principle of fluid mechanics—the wall effect. Using only a small amount of compressed air as a power source, they drive the surrounding airflow to form a high-pressure, high-speed airflow, which draws down from inside the weighing chamber into the down filling tube. The down filling tube then fills the areas requiring down filling. Currently, for different types of down filling targets, some targets have a large down weight, while others have a small down weight. In these cases, amplifiers with different suction capacities need to be replaced, and the down filling pipes also need to be replaced accordingly. The amplifier is generally installed inside the down filling machine at the down outlet. Replacing the amplifier requires disassembling the inside of the down filling machine, a complex process that affects the down filling efficiency. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a down output mechanism with flexible switching of down filling weight.

[0004] To achieve the above objectives, this utility model provides a down outlet mechanism with flexibly switchable down filling weight. Its innovation lies in the fact that its structure includes a first amplifier, a fixed tube, a sleeve, a first central tube, and a down filling tube connected in series. The ventilation volume of the first central tube is matched with the exhaust volume of the first amplifier. The fixed tube, sleeve, first central tube, and down filling tube are connected in series by threads.

[0005] Furthermore, the fabric extraction mechanism of this utility model also includes a second amplifier and a second central tube. The exhaust volume of the second amplifier and the ventilation volume of the second central tube are matched. The exhaust volume of the second amplifier is less than that of the first amplifier, and the diameter of the second central tube is less than that of the first central tube.

[0006] The second amplifier is clamped between the fixed tube and the sleeve by a vacuum clamp, and the second central tube replaces the first central tube and is threaded between the sleeve and the wool filling tube.

[0007] Furthermore, the aforementioned fixing pipe is a bent pipe, and a fixing plate is fitted onto the fixing pipe, with fixing holes provided at all four corners of the fixing plate.

[0008] The technical effects and advantages of this utility model are as follows: When dealing with objects with different fill weights, this utility model does not require replacing the first amplifier connected inside the filler machine, nor does it require removing the fixing tube from the filler machine. It only requires disassembling and installing the second amplifier, the first center tube, and the second center tube. The disassembly and installation process is convenient and improves the filler efficiency of the objects. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0013] like Figure 1 In one specific implementation of this embodiment, the structure includes a first amplifier 1, a fixed tube 12, a sleeve 14, a first central tube 15, and a filling tube 16 connected in series. The ventilation volume of the first central tube 15 is matched with the exhaust volume of the first amplifier 1. The fixed tube 12, the sleeve 14, the first central tube 15, and the filling tube 16 are connected in series by threads.

[0014] This embodiment is applied to a target with a relatively large fill weight. Based on this target, this embodiment selects a first amplifier 1 with a large exhaust volume and a first central tube 15 with a large diameter. The exhaust volume of the first amplifier 1 and the ventilation volume of the first central tube 15 are matched to meet the fill weight requirements of the target. Example

[0015] Based on Example 1, such as Figure 2 In one specific implementation of this embodiment, the structure further includes a second amplifier 11 and a second central tube 2. The exhaust volume of the second amplifier 11 is matched with the ventilation volume of the second central tube 2. The exhaust volume of the second amplifier 11 is less than that of the first amplifier 1, and the diameter of the second central tube 2 is less than that of the first central tube 15.

[0016] When the second amplifier 11 is clamped between the fixed tube 12 and the sleeve 14 by a vacuum clamp, the second central tube 2 replaces the first central tube 15 and is threaded between the sleeve 14 and the wool filling tube 16.

[0017] This embodiment is applied to objects with a relatively small fill weight. Based on this object, this embodiment selects a second amplifier 11 with a smaller exhaust volume. The replacement process of the blow-down mechanism is as follows: the connection position of the first amplifier 1 remains unchanged, the fixed tube 12 and the sleeve 14 are disassembled, and then the second amplifier 11 is clamped between the fixed tube 12 and the sleeve 14 using a vacuum clamp (this clamp can be a vacuum clamp from Shuntai on the market, model: KF10). Then, the first central tube 15 is removed from the connection between the sleeve 14 and the fill tube 16. Finally, the second central tube 2 is connected between the sleeve 14 and the fill tube 16. The above process completes the replacement of the blow-down mechanism.

[0018] The specific down filling process is as follows: the first amplifier 1 is in the off state, and the second amplifier 11 is directly turned on. The exhaust volume of the second amplifier 11 matches the ventilation volume of the second central tube 2 to meet the down filling weight requirement of the object in this embodiment.

[0019] Combining Embodiment 1 and Embodiment 2, as Figure 3 As shown, the structure of the fixing tube 12 is as follows: the fixing tube 12 is a bent tube, and a fixing plate 3 is fitted on the fixing tube 12. The four corners of the fixing plate 3 are provided with fixing holes 31. The fixing plate 3 is fixed to the filling machine through the fixing holes 31, thereby fixing the fixing tube 12 to the filling machine and ensuring that the fixing tube 12 and the first amplifier 1 are stably connected inside the filling machine. When dealing with objects with different filling weights, it is not necessary to replace the first amplifier 1 connected inside the filling machine, nor is it necessary to remove the fixing tube 12 from the filling machine. It is only necessary to disassemble and install the second amplifier 11, the first central tube 15, and the second central tube 2. The disassembly and installation process is convenient and improves the filling efficiency of the filling object.

[0020] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
