[0033] The specific implementation process of this utility model will be described below through several embodiments.

[0034] Example 1

[0035] See Figures 1 to 7 This embodiment discloses a specific implementation of a bag discharge device.

[0036] See Figures 1 to 7The bag discharge device includes a bag clamping assembly 1, a gas distribution assembly 2, and a discharge assembly 3. The discharge assembly 3 includes a discharge hub 31, a discharge guide plate 32, a negative pressure adsorption zone 33 disposed on the surface of the discharge hub 31, and several guide belts 34 embedded in the surface of the discharge hub 31. The guide belts 34 wrap around the discharge hub 31 and the discharge guide plate 32. Several annular grooves 312 are disposed on the surfaces of both the discharge hub 31 and the negative pressure adsorption zone 33. The guide belts 34 are embedded in the annular grooves 312, and under negative pressure adsorption... In the auxiliary zone 33, negative pressure holes 332 are provided between adjacent annular grooves 312, and a number of negative pressure holes 332 are arranged in a row along the axial direction of the discharge hub 31; the bag clamping assembly 1 clamps and delivers the bag to the negative pressure adsorption zone 33, the discharge hub 31 rotates and delivers the bag adsorbed by the negative pressure adsorption zone 33 to the discharge guide plate 32, the guide belt 34 carries the bag away from the negative pressure adsorption zone 33 and completes the discharge after passing through the discharge guide plate 32; the gas distribution assembly 2 distributes gas to the negative pressure adsorption zone 33.

[0037] Specifically, see Figures 1 to 7 The bag conveying assembly 1 includes an upper belt assembly 11 and a lower belt assembly 12, which convey the bag between the upper belt assembly 11 and the lower belt assembly 12. A pressure roller 35 is also provided above the discharge hub 31. The bag conveying assembly 1 transports the bag between the discharge hub 31 and the pressure roller 35, and the pressure roller 35 presses the bag against the negative pressure adsorption zone 33. Vertical plates 311 are respectively provided at both ends of the discharge hub 31. A screw adjusting assembly 351 is provided between the pressure roller 35 and the vertical plates 311. 351 is used to adjust the distance between the pressing roller 35 and the discharge hub 31; to improve the discharge efficiency of the bag, the four negative pressure adsorption zones 33 are evenly distributed on the surface of the discharge hub 31; the discharge guide plate 32 is vertical and installed on the vertical wall 311, the top of the discharge guide plate 32 is provided with a sloping transition surface 321, the guide belt 34 wraps around the discharge hub 31 and the discharge guide plate 32, and for every 1 / 4 turn of the discharge hub 31, the guide belt 34 carries the bag away from the negative pressure adsorption zone 33 and completes the discharge after passing through the discharge guide plate 32.

[0038] See Figures 1 to 7The working principle of the gas distribution assembly is as follows: The gas distribution assembly 2 includes a gas distribution cam 21, a gas distribution valve 22, a first gas distribution pipe 23, a gas distribution shaft 24, and four second gas distribution pipes 25. One end of the first gas distribution pipe 23 is connected to the gas distribution valve 22. The gas distribution cam 21 has a cam surface 211. The cam surface 211 drives the gas distribution valve 22 to open through the swing arm 26. The negative pressure adsorption zone 33 generates negative pressure and adsorbs the bag body. The four negative pressure adsorption zones 33 are evenly distributed on the surface of the discharge hub 31. Each of the four gas distribution cams 21 and 22 is connected to the gas distribution valve 22. The second gas distribution pipe 25 connects to the corresponding gas distribution hole 331 of the negative pressure adsorption zone 33, and the gas distribution hole 331 is connected to each negative pressure hole 332; four first gas distribution holes 241 are equally spaced along the axial direction of the gas distribution shaft 24, and the four first gas distribution holes 241 are arranged in a circle; the second gas distribution pipe 25 extends into the gas distribution shaft 24 and connects to the corresponding first gas distribution hole 241; the air extraction port 231 of the first gas distribution pipe 23 is aligned with the circumference formed by the four first gas distribution holes 241; see also Figure 7 Let's take one of the first air distribution ports, 241, as an example for explanation. Figure 7 The shaded area in (a) is one of the first air distribution holes 241. When the discharge hub 31 rotates, the first air distribution hole 241 in (a) first slightly intersects with the air extraction port 231 of the first air distribution pipe 23. This state is the starting point for the matching of the cam surface 11 and the air distribution valve 22. The air distribution valve 22 is open, and the negative pressure adsorption zone 33 generates negative pressure. The bag body is adsorbed between the discharge hub 31 and the pressure roller 35. When the first air distribution hole 241 in (a) rotates to Figure 7 In state (b), the discharge hub 31 has rotated approximately 90° in the direction of the arrow. The bag is conveyed from between the discharge hub 31 and the pressing roller 35 to the vicinity of the discharge guide plate 32. This state is the endpoint of the matching cam surface 11 and the air distribution valve 22. The first air distribution hole 241 and the air extraction port 231 of the first air distribution pipe 23 no longer intersect. The air distribution valve 22 is closed, the negative pressure adsorption zone 33 returns to normal pressure, and the guide belt 34 carries the bag away from the negative pressure adsorption zone 33 and through the discharge guide plate 32 to complete the discharge. In this cycle, for every 1 / 4 turn of the discharge hub 31, the guide belt 34 carries the bag away from the negative pressure adsorption zone 33 and through the discharge guide plate 32 to complete the discharge of one bag.
