[0028] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be construed as a limitation on the protection scope of the present invention.

[0029] In the description of the present invention, if first, second, and third are described, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0030] In the present invention, unless otherwise clearly defined, terms such as "arranged", "installed", "connected", etc. should be understood in a broad sense. For example, they can be directly connected, or indirectly connected through an intermediate medium; they can be fixedly connected, or detachably connected, or integrally formed; they can be mechanically connected; they can be the connection inside two components or the interaction relationship between two components. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0031] Referring to Figures 1 to 5 , an opening device according to an embodiment of the present invention includes a mounting bracket 100, an opening mechanism 200, and an opening holding mechanism. The opening mechanism 200 is arranged on the mounting bracket 100, and the opening mechanism 200 can open the film bag. The opening holding mechanism is arranged on the mounting bracket 100, and the opening holding mechanism can maintain the opening state of the film bag.

[0032] Specifically, the opening mechanism 200 includes a third driving member 210, two nozzle brackets 220, and two opening nozzles 230. The third driving member 210 is disposed on the mounting frame 100. The two nozzle brackets 220 are arranged oppositely. The third driving member 210 is connected to the two nozzle brackets 220 so as to be able to drive the two nozzle brackets 220 to move relatively, that is, move towards and away from each other. The two opening nozzles 230 are arranged oppositely. The two opening nozzles 230 are respectively connected to the two nozzle brackets 220 in one-to-one correspondence, and the opening nozzles 230 can adsorb the side surface of the film bag. The opening holding mechanism includes two clamps 310. The two clamps 310 are both disposed on the mounting frame 100. The two clamps 310 are arranged at intervals, and the two clamps 310 can respectively clamp the corresponding side of the film bag. The third driving member 210 can be a cylinder, a hydraulic cylinder, an electric push rod, etc.

[0033] In this embodiment, the two clamps 310 respectively clamp the corresponding side of the film bag to fix the film bag. The third driving member 210 drives the two nozzle brackets 220 to move towards each other, so that the two opening nozzles 230 on the two nozzle brackets 220 respectively adsorb one side surface of the film bag. The third driving member 210 drives the two nozzle brackets 220 to move away from each other, so that the two side surfaces of the film bag adsorbed by the two opening nozzles 230 move away from each other, thereby opening the film bag. During this process, the two clamps 310 always maintain the clamping state. When the film bag is opened, the two opening nozzles 230 stop adsorbing, and the position of the film bag in the clamps 310 changes. It is precisely because the two clamps 310 always maintain the clamping state that the film bag cannot return to the initial position after changing the position, that is, the film bag cannot retract after being opened.

[0034] It can be understood that the acting force of the above-mentioned opening nozzle 230 on the film bag is greater than the acting force of the two clamps 310 on the film bag.

[0035] In some embodiments, the two clamps 310 respectively clamp the corresponding side of the film bag to fix the film bag. The third driving member 210 drives the two nozzle brackets 220 to move towards each other, so that the two opening nozzles 230 on the two nozzle brackets 220 respectively adsorb one side surface of the film bag. After the opening nozzles 230 complete adsorption, the third driving member 210 drives the two nozzle brackets 220 to move away from each other, so that the two side surfaces of the film bag move away from each other to open the film bag. During this process, the clamping parts of the two clamps 310 move relatively to maintain the opening state of the film bag.

[0036] In some embodiments, the third driving member 210 drives the two suction nozzle brackets 220 to move towards each other, so that the two opening suction nozzles 230 on the two suction nozzle brackets 220 respectively adsorb one side of the film bag. After the opening suction nozzles 230 complete the adsorption, the third driving member 210 drives the two suction nozzle brackets 220 to move away from each other, so that the two sides of the film bag move away from each other to open the film bag. When the film bag is opened, the two clamping members 310 respectively clamp the corresponding side of the film bag. After the opening is kept fixed, the two opening suction nozzles 230 stop adsorbing. During this process, the two clamping members 310 clamp one side of the film bag only after the film bag is opened. At this time, the film bag clamped by the two clamping members 310 has already undergone an opening deformation, and this opening deformation is affected by the clamping of the two clamping members 310 and thus cannot recover, that is, the film bag cannot retract after being opened.

[0037] Referring to Figure 3 , the clamping member 310 includes a clamping bracket 311, two first driving members 312 and two clamping blocks 313. The clamping bracket 311 is arranged on the mounting frame 100. The two first driving members 312 are arranged oppositely. Both of the two first driving members 312 are connected to the clamping bracket 311. The two clamping blocks 313 are arranged oppositely. The two first driving members 312 are respectively connected to the two clamping blocks 313 in a one-to-one correspondence so as to be able to drive the two clamping blocks 313 to move relatively, that is, to move towards each other and away from each other. The first driving member 312 can be a cylinder, a hydraulic cylinder, an electric push rod, etc.

[0038] At least one of the two clamping members 310 is slidably arranged on the mounting frame 100, that is, among the two clamping members 310, at least one clamping bracket 311 is slidably arranged on the mounting frame 100. The slidable arrangement of the clamping bracket 311 can be used to adjust the distance between the two clamping brackets 311, that is, to adjust the distance between the two clamping members 310.

[0039] In this embodiment, the clamping bracket 311 is provided with a slider 311A, and the mounting frame 100 is provided with a slide rail 110. The two clamping brackets 311 are both slidably connected to the mounting frame 100 through the slider 311A and the slide rail 110.

[0040] In some embodiments, the slider 311A can be arranged on the mounting frame 100, and the slide rail 110 can be arranged on the clamping bracket 311.

[0041] In some embodiments, the clamping bracket 311 is connected to the mounting frame 100 through a fixing member to prevent the clamping member 310 from sliding during the clamping action. Specifically, a plurality of positioning holes are provided on the mounting frame 100, and the plurality of positioning holes are arranged in sequence along the sliding direction of the clamping bracket 311. The fixing member passes through the positioning hole and is connected to the clamping bracket 311 to be able to fix the clamping bracket 311 to the mounting frame 100.

[0042] Referring to Figure 2, a driving mechanism 400 is further provided on the mounting bracket 100. The driving mechanism 400 can drive the two clamps 310 to move relatively, that is, move towards and away from each other. Specifically, the driving mechanism 400 includes a connecting member 410, two connecting plate strips 420, and a second driving member 430. One ends of the two connecting plate strips 420 are respectively rotatably connected to the connecting member 410, and the other ends of the two connecting plate strips 420 are respectively rotatably connected to the corresponding clamp brackets 311. The second driving member 430 is provided on the mounting bracket 100, and the second driving member 430 is connected to the connecting member 410 to be able to drive the connecting member 410 to move up and down. The second driving member 430 can be a cylinder, a hydraulic cylinder, an electric push rod, etc.

[0043] When it is necessary to shorten the distance between the two clamps 310, the second driving member 430 drives the connecting member 410 to rise. The connecting member 410 rises and pulls the two clamp brackets 311 to move towards each other through the two connecting plate strips 420 on the connecting member 410, so as to realize the action of shortening the distance between the two clamps 310; when it is necessary to increase the distance between the two clamps 310, the second driving member 430 drives the connecting member 410 to descend. The connecting member 410 descends and pushes the two clamp brackets 311 to move towards each other through the two connecting plate strips 420 on the connecting member 410, so as to realize the action of increasing the distance between the two clamps 310. Of course, under the limiting effect of the driving mechanism 400, the two clamps 310 will not slide during the clamping action.

[0044] Through the above structure, under the driving effect of the second driving member 430, the distance adjustment between the two clamps 310 does not require human participation, thereby optimizing the user experience.

[0045] In some embodiments, the second driving member 430 is connected to a control device to be able to accurately adjust the distance between the two clamps 310.

[0046] The present invention also proposes a welding nozzle machine, which includes the above-mentioned opening device. Through the above opening device, it is possible to effectively prevent the opened film bag from retracting the opening.

[0047] Of course, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations and substitutions are all included in the scope defined by the claims of this application.
