[0029] Embodiment 1:

[0030] Please refer to Figures 1-5 , the above technical solutions of the present invention are described in detail through the following embodiments:

[0031] A mask bag opening device, comprising:

[0032] A suction cup assembly 1, the suction cup assembly 1 includes a suction cup 11, the tail end of the suction cup 11 is clamped with an extension rod 12, the tail of the extension rod 12 is connected with a driving device 2 through an adjusting assembly, the adjusting assembly is used to adjust the distance between two adjacent extension rods 12, and an auxiliary clamping device 3 is arranged above the suction cup 11.

[0033] The suction cup 11 is made of a rubber suction cup, and the extension rod 12 is made of a metal material. The suction cup 11 is used to adsorb the outer side of the mask bag.

[0034] The adjusting assembly includes a base 13, which is welded and installed at the tail end of the extension rod 12. A clamping block 14 is welded to the tail end of the base 13, and a fixing bolt 15 is installed on the top of the clamping block 14 by threading.

[0035] The fixing bolt 15 passes through the clamping block 14, and rotating the fixing bolt 15 can drive the fixing bolt 15 to move up and down.

[0036] The driving device 2 includes an adjusting frame 22. The adjusting frame 22 is connected to the adjusting assembly through an adjusting guide rail 23. A sliding rod 24 is provided on the side of the adjusting frame 22. The heads of the sliding rods 24 on the same side are in contact with each other. Below the heads of the sliding rods 24, a lifting cylinder 28 is connected through a pressing block 27.

[0037] The tail end of the base 13 is slidably connected to the adjusting guide rail 23 through the clamping block 14, and the bottom surface of the fixing bolt 15 abuts against the adjusting guide rail 23. Loosen the fixing bolt 15, and the base 13 can slide along the adjusting guide rail 23 through the clamping block 14, so as to adjust the distance between two adjacent extension rods 12, and then adapt to mask bags of different sizes.

[0038] The top of the pressing block 27 is triangular. The side surface of the top of the pressing block 27 abuts against the heads of the two sliding rods 24. By controlling the extension or retraction of the piston rod of the lifting cylinder 28, the pressing block 27 can be driven to rise or retract, so as to drive the pressing block 27 to insert between the two sliding rods 24 or withdraw from between the two sliding rods 24.

[0039] The driving device 2 further includes a fixing plate 21. Guide frames 25 are fixedly installed on both sides of the fixing plate 21 through bolts. The sliding rod 24 is slidably connected to the guide frame 25, and a return spring 26 is provided between the head of the sliding rod 24 and the guide frame 25.

[0040] The return spring 26 is sleeved on the sliding rod 24, and both ends of the return spring 26 abut against the head of the sliding rod 24 and the guide frame 25 respectively.

[0041] When the pressing block 27 moves upward, it can drive the sliding rods 24 to move away from each other, and at the same time compress the return spring 26. The sliding rods 24 moving away from each other can drive the adjusting frames 22 to move away from each other, so as to drive the extension rods 12 to move away from each other, and then drive the suction cups 11 to move away from each other.

[0042] When the pressing block 27 moves downward, under the elastic force of the return spring 26, the sliding rods 24 approach each other. The sliding rods 24 approaching each other can drive the adjusting frames 22 to approach each other, so as to drive the extension rods 12 to approach each other, and then drive the suction cups 11 to approach each other.

[0043] The auxiliary clamping device 3 includes a positioning frame 31. At the top of the positioning frame 31 on the side facing the suction cup 11, a clamping frame 33 is rotatably installed through a rotating frame 35. The inner side of the front part of the clamping frame 33 abuts against the front side of the suction cup 11. The rear part of the clamping frame 33 is slidably connected to the sliding rod 24 through an opening shaft 36.

[0044] When the inner side of the front part of the clamping frame 33 abuts against the front side of the suction cup 11, the clamping frame 33 cooperates with the suction cup 11 to clamp both the inner and outer sides of the facial mask bag, preventing the facial mask bag from deforming.

[0045] The auxiliary clamping device 3 further includes a positioning frame 31. The positioning frame 31 is fixedly installed between two fixing plates 21 through bolts. A regulating hole 32 is provided through the middle of the positioning frame 31, and the extension rod 12 passes through the regulating hole 32.

[0046] The positioning frame 31 is immovable, and the extension rod 12 can move axially within the regulating hole 32.

[0047] At the front and rear sides of the top of the clamping frame 33 near the positioning frame 31, rotating shafts 34 are welded. The rotating shafts 34 are rotatably connected to the rotating frame 35.

[0048] The rotating frame 35 is fixedly installed at the top of the positioning frame 31 on the side facing the suction cup 11 through screws. The positioning frame 31 can rotate about the axis of the rotating shaft 34.

[0049] The clamping frame 33 includes a clamping plate 331 and a driven plate 332. The inner side of the clamping plate 331 abuts against the front side of the suction cup 11.

[0050] The clamping plate 331 is used to cooperate with the suction cup 11 to clamp the facial mask bag.

[0051] The driven plate 332 is slidably connected to the opening shaft 36, and the opening shaft 36 is rotatably connected to the extension rod 12.

[0052] When the extension rod 12 moves axially, it can drive the opening shaft 36 to move along the axis of the extension rod 12, thereby driving the driven plate 332 to move along the axis of the extension rod 12. Since the rotating shaft 34 is rotatably connected to the rotating frame 35, when the driven plate 332 moves along the axis of the extension rod 12, the clamping plate 331 and the driven plate 332 can rotate about the axis of the rotating shaft 34.

[0053] When the driven plate 332 rotates about the axis of the rotating shaft 34, it can drive the opening shaft 36 to rotate and at the same time slide with the opening shaft 36.

[0054] When the extension rods 12 approach each other, the clamping plate 331 rotates upward. When the extension rods 12 move away from each other, the clamping plate 331 rotates downward.

[0055] When an operator uses this device in this embodiment, the piston rod of the lifting cylinder 28 is controlled to extend, driving the extrusion block 27 to rise. The extrusion block 27 is inserted between the two sliding rods 24, driving the sliding rods 24 to move away from each other, and at the same time compressing the return spring 26. The sliding rods 24 moving away from each other can drive the adjusting frames 22 to move away from each other, thereby driving the extension rods 12 to move away from each other, and further driving the suction cups 11 to move away from each other.

[0056] Place the mask bag between the suction cups 11.

[0057] The piston rod of the lifting cylinder 28 is controlled to retract, driving the extrusion block 27 to rise and driving the extrusion block 27 to move downward. Under the elastic force of the return spring 26, the sliding rods 24 approach each other. The sliding rods 24 approaching each other can drive the adjusting frames 22 to approach each other, thereby driving the extension rods 12 to approach each other, and further driving the suction cups 11 to approach each other. The suction cups 11 clamp the outer side of the mask bag from both left and right sides, and the suction cups 11 are adsorbed to the mask bag.

[0058] The piston rod of the lifting cylinder 28 is controlled to extend again, driving the extension rods 12 and the suction cups 11 to move away from each other, and using the adsorption effect of the suction cups 11 to open the mask bag from left and right.

[0059] When the extension rods 12 move away from each other, the opening shaft 36 is driven to move along the axis direction of the extension rods 12, thereby driving the driven plate 332 to move along the axis direction of the extension rods 12, and further driving the clamping plate 331 to rotate downward until the inner side of the clamping plate 331 abuts against the suction cups 11, clamping both the inner and outer sides of the mask bag.
