DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0018] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0019] Please refer to Figure 1 and Figure 2 As shown, the present invention discloses a semi-automatic bag opening device, which is used to open a packaging bag A and stretch out the lining unit inside the packaging bag. The device includes a fixed plate 10, a stretching plate 20 and two transmission assemblies 30. The stretching plate 20 and the two transmission assemblies 30 are both arranged on the same side of the fixed plate 10. One end of one transmission assembly 30 is connected to one end of the fixed plate 10, and one end of the other transmission assembly 30 is connected to the other end of the fixed plate 10. The two transmission assemblies 30 are arranged opposite to each other, one end of the stretching plate 20 is connected to the fixed plate 10, and the stretching plate 20 is arranged between the two transmission assemblies 30. There is a gap 40 between the stretching plate 20 and the two transmission assemblies 30. The two transmission assemblies 30 correspond to the two side edges in the width direction of the packaging bag, respectively. The two transmission assemblies 30 are used to clamp the two sides in the width direction of the packaging bag and drive the packaging bag to move toward one side of the fixed plate 10.

[0020] When using the device, the user first inserts the opening of the packaging bag into the end of the expansion plate 20, and extends the two edges of the packaging bag into the two transmission assemblies 30. The packaging bag is driven by the two transmission assemblies 30 to move toward the side of the fixed plate 10 to expand the cushioning unit inside the packaging bag to achieve a buffering protection effect. Then the transmission assembly drives the packaging bag to move toward the side away from the fixed plate to withdraw the packaging bag.

[0021] In an optional embodiment, the transmission assembly 30 includes an upper transmission belt assembly 31 and a lower transmission belt assembly 32 which are arranged relatively to each other. The upper transmission belt assembly 31 includes an upper driving shaft 311, an upper driven shaft 312 and an upper transmission belt 313. The upper driving shaft 311 and the upper driven shaft 312 are arranged at intervals, and the upper transmission belt 313 is sleeved on the upper driving shaft 311 and the upper driven shaft 312. The upper driving shaft 311 is driven to rotate by a motor, and the upper driving shaft 311 drives the upper transmission belt to rotate.

[0022] The lower transmission belt assembly 32 includes a lower driving shaft 321, a lower driven shaft 322 and a lower transmission belt 323. The lower driving shaft 321 and the lower driven shaft 322 are arranged at intervals. The lower transmission belt 323 is sleeved on the lower driving shaft 321 and the lower driven shaft 322. The upper driving shaft 311 is connected to the lower driving shaft 321 by transmission. The specific transmission connection method can be a gear transmission connection method. There is a certain gap between the upper transmission belt 313 and the lower transmission belt 323, and this gap is used to clamp one side of the packaging bag. The two upper transmission belts 313 and the lower transmission belt 323 are used to clamp the two sides of the packaging bag in the width direction, thereby driving the packaging bag to move. During the movement of the packaging bag, the padding unit inside the packaging bag is opened by the opening member.

[0023] In this embodiment, power is provided by a motor, and the motor rotates to drive the upper transmission belt and the lower transmission belt to rotate. When the motor rotates forward, the packaging bag moves toward the side of the fixed plate. At this time, the expansion plate enters into the packaging bag to expand the lining unit. The motor reverses to move the packaging bag away from the fixed plate to send out the packaging bag with the expanded lining unit.

[0024] In an optional embodiment, the length of the opening plate 20 is less than the length of the transmission assembly 30. By setting the length of the opening plate 20 to be less than the length of the transmission assembly 30, it is convenient for the two sides of the packaging bag to first enter the gap between the upper transmission belt 313 and the lower transmission belt 323.

[0025] In an optional embodiment, the transmission assembly 30 further includes a housing 33, the upper transmission belt assembly 31 and the lower transmission belt assembly 32 are both disposed in the housing 33, and a slot 331 is disposed in the housing 33 at a position directly opposite to the position between the upper transmission belt assembly 31 and the lower transmission belt assembly 32. That is, the gap between the upper transmission belt 313 and the lower transmission belt 323 corresponds to the position of the slot 331, and the slot 331 is used for the side movement of the packaging bag.

[0026] In an optional embodiment, the expansion plate 20 is arranged at a position directly opposite to the position between the upper transmission assembly 30 and the lower transmission belt assembly 32, that is, the expansion plate 20 corresponds to the middle position of the packaging bag, so as to move the packaging bag in the direction and expand the padding unit inside the packaging bag.

[0027] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
