The mouth-opening assemblies are symmetrically arranged on the base, hooking onto the mouth of the packaging bag and holding it open. The driving member is arranged on the base, driving the two sets of mouth-opening assemblies to move toward or away from each other. The mouth-pressing member is arranged at the upper end of the mouth-opening assembly to press the mouth of the packaging bag.

[0008] Preferably, the driving member includes a connecting plate symmetrically arranged at the lower end of the base; a sliding rod is connected between the two connecting plates, and is rotatably connected to a bidirectional screw rod; one end of the bidirectional screw rod is connected to a driving mechanism; the two base plates are symmetrically threadedly connected to the bidirectional screw rod, and are respectively slidably connected to the sliding rod; a plurality of sliding grooves are opened on the base; the telescopic mechanism and the connecting column are respectively slidably connected to one part of the sliding groove.

[0009] Preferably, the pressure piece is respectively arranged on the opposite side of the two sliding plates; the pressure piece includes a connecting column 2 arranged on the sliding plate; the other end of the connecting column 2 is connected to the connecting plate 2; the end of the connecting plate 2 facing the sliding plate is connected to a spring; the other end of the spring is connected to the pressure plate.

[0011] Preferably, the opposite sides of the two side support plates are arranged in an arc shape.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] (1) The bag holding device of the cement packaging machine is constructed by hanging the four corners of the bag opening on four hooks respectively, and using a spring to push the pressure plate to press the bag opening onto the sliding plate. Then, the driving mechanism is started to drive the bidirectional screw to rotate, thereby driving the two sets of opening components to move in opposite directions, and the bag opening is fully opened.

At the same time, it can also adapt to bags of different sizes, expanding the application range of the device.

[0014] (2) The bag support device of the cement packaging machine activates the telescopic mechanism to drive the sliding plate to slide up and down along the fixed plate, so that the bottom of the bag is placed exactly on the bottom support plate. At the same time, the side support plates are on both sides of the bottom of the bag, so that the bottom support plate and the side support plates jointly provide support for the bag. This can prevent the bag from sliding off the hook due to excessive load, and keep the bag stable during the cement filling process. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example 1

[0021] like Figure 1-3 As shown, the present invention proposes a bag-holding device for a cement packaging machine, comprising a base 1, a mouth-opening assembly 2, a driving member 3, a mouth-holding member 4, and a supporting member 5. The mouth-holding assemblies 2 are symmetrically arranged on the base 1, hooking onto the mouth of the packaging bag and holding it open. The driving member 3 is arranged on the base 1, driving the two sets of mouth-holding assemblies 2 to move toward or away from each other. The mouth-holding member 4 is arranged at the upper end of the mouth-holding assembly 2 to press the mouth of the packaging bag. The supporting member 5 is arranged at the lower end of the mouth-holding assembly 2 to provide support for the bottom of the packaging bag.

[0022] To further illustrate, the opening assembly 2 includes a base plate 21; a fixed plate 22 is positioned above the base plate 21; the fixed plate 22 and base plate 21 are connected by a connecting column 23. The upper end of the fixed plate 22 is open, and a sliding plate 24 is slidably connected to the opening. A telescopic mechanism 25 is positioned on either side of the sliding plate 24. The telescopic mechanism 25 is an electrically operated telescopic rod. The fixed end of the telescopic mechanism 25 is connected to the base plate 21, and the telescopic end is connected to the sliding plate 24. A hook 26 is positioned at the upper end of the telescopic end. This hook can be used to hold the opening of the cement bag open, thereby facilitating cement filling. The fixed plate 22 and sliding plate 24 respectively hold down the bag from both sides, providing support and preventing it from slipping.

[0023] Further explanation: the drive member 3 comprises connecting plates 1 (31) symmetrically arranged at the lower end of the base 1. A slide rod 34 is connected between the two connecting plates 1 (31), and a bidirectional screw rod 32 is rotatably connected to the two connecting plates 1 (31). One end of the bidirectional screw rod 32 is connected to a drive mechanism 33, which is a motor. The two bottom plates 21 are symmetrically threaded onto the bidirectional screw rod 32 and are each slidably connected to the slide rod 34. The base 1 is provided with multiple slide grooves 1 (35). The telescopic mechanism 25 and the connecting column 1 (23) are slidably connected to the slide grooves 1 (35). This drives the two opening assemblies 2 to move toward and away from each other, thereby fully opening the bag opening, improving support for the bag and preventing it from slipping when filling with cement. The device can also accommodate bags of varying sizes, expanding its application range.

[0024] To further illustrate, the pressure member 4 is disposed on opposite sides of the two sliding plates 24. The pressure member 4 includes a second connecting post 41 disposed on the sliding plate 24; the other end of the second connecting post 41 is connected to a second connecting plate 42; the end of the second connecting plate 42 facing the sliding plate 24 is connected to a spring 43; the other end of the spring 43 is connected to a pressure plate 44. This can suppress the opening of the packaging bag, further preventing the packaging bag from slipping off the hook 26.

[0025] Example 2

[0026] like Figure 4 As shown, the present invention proposes a bag supporting device for a cement packaging machine. Compared with the first embodiment, this embodiment further includes: a supporting member 5 includes a bottom support plate 51 arranged above the base 1; the bottom support plate 51 is connected to the base 1 via a third connecting plate 52, and two chute grooves 53 are respectively provided at both ends of the bottom support plate 51; a slide plate 54 is slidably connected to each of the two chute grooves 53; the other ends of the two slide plates 54 are respectively connected to a side support plate 55; and the two side support plates 55 are respectively connected to the fixed plate 22 on the corresponding side. The bottom support plate 51 and the hook 26 cooperate with each other to ensure that the bottom of the packaging bag can be properly supported by the bottom support plate 51. The side support plates 55 cooperate with the driving member 3 to ensure that the side support plates 55 can provide support for the bottom of the packaging bag on both sides. This can prevent the packaging bag from sliding off the hook 26 due to excessive load, and keep the packaging bag stable during the cement filling process.

[0027] To further illustrate, the two side support plates 55 are arranged on opposite sides in an arc shape, so that the side support plates 55 can better fit with the two sides of the bottom of the packaging bag, thereby providing more stable support therefor.

[0028] The working principle of the present utility model is as follows: During operation, the four corners of the bag opening are first hung on the four hooks 26, and the spring 43 pushes the pressure plate 44 to press the bag opening against the sliding plate 24. Next, the drive mechanism 33 is activated to rotate the bidirectional screw 32, thereby driving the two sets of opening assemblies 2 to move in opposite directions, opening the bag opening. Simultaneously, the side support plates 55 and the slide plate 54 will move in opposite directions following the opening assemblies 2. Next, the telescopic mechanism 25 is activated, driving the slide plate 24 to slide up and down along the fixed plate 22, so that the bottom of the bag is precisely placed on the bottom support plate 51. At the same time, the side support plates 55 will be on both sides of the bottom of the bag, so that the bottom support plate 51 and the side support plates 55 jointly provide support for the bag. Finally, the bag can be filled with cement.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
