[0032] Embodiment 1:

[0033] Please refer to Figure 1-6 , this embodiment provides a film clamping and bag opening component of an automatic bagging machine for formulated cut tobacco, which includes a translation device 10, and a first film clamping device 20 and a second film clamping device 30 are arranged on the translation device 10;

[0034] The translation device 10 includes a mounting frame 11, a first mounting plate 12 and a second mounting plate 13. The mounting frame 11 is used to provide support and a mounting base for each component, and the film clamping and bag opening component is mounted on the bagging machine frame through the mounting frame 11. The first mounting plate 12 is used to mount the first film clamping device 20, and the second mounting plate 13 is used to mount the second film clamping device 30. Specifically, slide rails are formed on the mounting frame 11. The slide rails are arranged along the length direction of the mounting frame 11, and the number of slide rails is 2. A slider adapted to the slide rail is fixed on the back of the first mounting plate 12, and the first mounting plate 12 is slidably connected to the mounting frame 11 through the slider and the slide rail. A slider adapted to the slide rail is fixed on the back of the second mounting plate 13, and the second mounting plate 13 is slidably connected to the mounting frame 11 through the slider and the slide rail. Thus, both the first mounting plate 12 and the second mounting plate 13 can be translated in the length direction of the mounting plate, and the first mounting plate 12 and the second mounting plate 13 can approach or move away from each other.

[0035] The first film clamping device 20 includes a first film clamping arm 21. The end of the first film clamping arm 21 is fixed to the first mounting plate 12. A support rib plate is arranged at the connection between the first film clamping arm 21 and the first mounting plate 12, so that the first film clamping arm 21 is vertically fixed to the side of the first mounting plate 12. The second film clamping device 30 includes a second film clamping arm 31. The end of the second film clamping arm 31 is fixed to the second mounting plate 13. A support rib plate is also arranged at the connection between the second film clamping arm 31 and the second mounting plate 13, so that the second film clamping arm 31 is vertically fixed to the side of the second mounting plate 13. The first film clamping arm 21 and the second film clamping arm 31 are arranged in parallel, and the first film clamping arm 21 and the second film clamping arm 31 can approach or move away from each other under the drive of the first mounting plate 12 and the second mounting plate 13.

[0036] A plurality of film opening clips 22 are arranged on the side of the first film clamping arm 21. A plurality of film opening clips 22 are arranged on the side of the second film clamping arm 31. In this embodiment, the number of film opening clips 22 on the first film clamping arm 21 is 2, and the number of film opening clips 22 on the second film clamping arm 31 is 2. The film opening clips 22 on the side of the first film clamping arm 21 and the film opening clips 22 on the side of the second film clamping arm 31 are arranged opposite to each other. The film opening clips 22 are used to clamp the plastic film layer at the mouth of the plastic bag. An opening bag channel for the plastic bag to pass through is formed between the first film clamping arm 21 and the second film clamping arm 31.

[0037] Based on the above structure, during the use process, in the initial state, the first film clamping arm 21 and the second film clamping arm 31 are far away from each other, leaving an opening channel for the plastic bag. After the plastic bag goes through the processes of film feeding, sealing, and cutting by the automatic bagging machine, it is positioned in the opening channel between the first film clamping arm 21 and the second film clamping arm 31. The first mounting plate 12 and the second mounting plate 13 drive the first film clamping arm 21 and the second film clamping arm 31 to approach each other respectively, so that the film opening clips 22 on the first film clamping arm 21 and the film opening clips 22 on the second film clamping arm 31 clamp both sides of the mouth of the plastic bag in the opening channel. The 4 film opening clips 22 clamp the plastic film in a "mutual" shape. Subsequently, the first mounting plate 12 and the second mounting plate 13 drive the first film clamping arm 21 and the second film clamping arm 31 to move away from each other respectively, so that the mouths of the plastic bags on the film opening clips 22 on the first film clamping arm 21 and the film opening clips 22 on the second film clamping arm 31 are opened. By moving the first mounting plate 12 and the second mounting plate 13 simultaneously, the translation of the plastic bag can also be realized, and it is positioned above the cardboard box. The film clamping and opening component of the formulated cut tobacco automatic bagging machine in this embodiment clamps the plastic film at the mouth of the bag through the film opening clips 22, and the translation device 10 drives the translation of the first film clamping arm 21 and the second film clamping arm 31 respectively, ensuring that the mouth of the bag is accurately and quickly opened and can be translated and positioned above the cardboard box, so that the subsequent filling and sealing operations can proceed smoothly. The bag opening efficiency is high and the flexibility is strong.

[0038] The first film clamping device 20 in this embodiment further includes a sliding component 23. The film opening clip 22 is connected to the first film clamping arm 21 through the sliding component 23, so that the film opening clip 22 can slide in the length direction of the first film clamping arm 21.

[0039] Specifically, the sliding component 23 includes a connecting frame and a sliding plate. The connecting frame and the sliding plate are connected to the sliding plate through a slide rail and slider mechanism. The sliding plate is fixedly connected to one side of the first film clamping arm 21, and the connecting frame is connected to the film opening clip 22, thereby realizing the sliding of the film opening clip 22 in the length direction of the first film clamping arm 21.

[0040] Furthermore, the first film clamping device 20 further includes a locking component 24. The locking component 24 is arranged at the connection between the film opening clip 22 and the first film clamping arm 21, and the relative position of the film opening clip 22 and the first film clamping arm 21 is fixed through the locking component 24.

[0041] Specifically, the locking component 24 includes a guide rod. A fixed block and a moving block are arranged on the guide rod. The outside of the fixed block is fixed to the connecting frame, the moving block is sleeved on the circumference of the guide rod, and the outside of the moving block is fixed to the first film clamping arm 21. A locking groove is opened on one side of the moving block, and a locking handle is arranged in the locking groove. The relative position of the moving block and the guide rod is locked by the way of clamping the shaft.

[0042] The relative positions of the two film-opening clips 22 on the first film-clamping arm 21 can be adjusted by the sliding component 23 and the locking component 24, so that the device has a certain adaptability and can be adjusted according to plastic bags or cartons of different sizes and shapes.

[0043] The film-opening clip 22 of this embodiment includes a connecting plate 221. One side of the connecting plate 221 is connected to the sliding component 23, and a slide rail is formed on the other side. The film-opening clip 22 further includes a film-clamping driving member 222, a fixing member 223 and a sliding member 224.

The film-clamping driving member 222 has a fixed end and a telescopic end; the fixing member 223 is connected to the fixed end of the film-clamping driving member 222; the end of the sliding member 224 is matched with the slide rail on the side of the connecting plate 221 through a slider, and the side of the sliding member 224 is connected to the telescopic end of the film-clamping driving member 222; a rubber sleeve 225 is sleeved on the fixing member 223 for clamping one end of the plastic film, and a rubber sleeve 225 is sleeved on the sliding member 224 for clamping one end of the plastic film. By the telescopic driving of the film-clamping driving member 222, the fixing member 223 and the sliding member 224 are moved closer to or away from each other, so as to clamp or release the mouth of the plastic bag, improve the clamping stability of the film-opening clip 22 for the mouth of the plastic bag, and avoid the plastic bag falling off during the bag-opening process.

[0044] The translation device 10 of this embodiment further includes a first translation component 14 and a second translation component 15. The first translation component 14 is used to drive the first mounting plate 12 to translate relative to the mounting frame 11, and the second translation component 15 is used to drive the second mounting plate 13 to translate relative to the mounting frame 11, so that their movements are independent of each other and do not interfere with each other, and the first film-clamping arm 21 or the second film-clamping arm 31 can be independently adjusted, with strong flexibility.

[0045] Specifically, the first translation component 14 is disposed between the first mounting plate 12 and the mounting frame 11; the first translation component 14 includes a first translation motor 141, a first belt 142, a first driving wheel 143 and a first driven wheel 144; the first driving wheel 143 is connected to one end of the mounting frame 11 through a fixed bearing seat, and the first driven wheel 144 is connected to the other end of the mounting frame 11 through a sliding bearing seat; thus, the first driven wheel 144 can approach or move away from the first driving wheel 143, facilitating loading and unloading and providing appropriate tension for the first belt 142. The first belt 142 is sleeved around the circumferences of the first driven wheel 144 and the first driving wheel 143. The first translation motor 141 is fixed to the mounting frame 11 through a motor bracket. The first translation motor 141 has an output end, and the output end is linked to the first driving wheel 143; the first mounting plate 12 is connected to the first belt 142 through a belt clamp. Driven by the first translation motor 141, the first mounting plate 12 fixed to the belt clamp is translated in the length direction of the mounting frame 11 by the first belt 142.

[0046] The second translation component 15 is disposed between the second mounting plate 13 and the mounting frame 11; the second translation component 15 includes a second translation motor, a second belt, a second driving wheel and a second driven wheel; the second driving wheel is connected to one end of the mounting frame 11 through a fixed bearing seat, and the second driven wheel is connected to the other end of the mounting frame 11 through a sliding bearing seat; the second belt is sleeved around the circumferences of the second driven wheel and the second driving wheel. The second translation motor is fixed to the mounting frame 11 through a motor bracket. The second translation motor has an output end, and the output end is linked to the second driving wheel; the second mounting plate 13 is connected to the second belt through a belt clamp.

[0047] The second film clamping device 20 of this embodiment has the same structure as the first film clamping device 30 and they are arranged oppositely. Those skilled in the art can understand and implement this, so it will not be elaborated here.

[0048] The vertical or parallel involved in this embodiment includes substantially vertical or substantially parallel. Those skilled in the art can understand this.

[0049] In the automatic bag - sleeving, bag - filling and sealing system for formulated cut tobacco, the bag - opening component of the bag - sleeving machine in the automatic bag - sleeving system is a very crucial component. After the plastic bag is clamped in the correct position, it is responsible for accurately and quickly opening the mouth of the bag so that subsequent filling and sealing operations can proceed smoothly. The film - clamping and bag - opening component of the automatic bag - sleeving machine for formulated cut tobacco in this embodiment clamps the plastic film at the mouth of the bag through the film - opening clamp 22, and the translation device 10 drives the translation of the first film - clamping arm 21 and the second film - clamping arm 31 respectively, providing sufficient force and speed to ensure that the mouth of the continuously fed bag is quickly and accurately opened to meet the requirements of the high - speed production line; the first film - clamping arm 21 and the second film - clamping arm 31 are independently controlled and have a large range of movement, avoiding problems such as improper or misaligned bag - mouth opening caused by positioning errors. The clamping and opening positions of each film - opening clamp 22 can be adjusted through the sliding component 23 and the locking component 24, enabling it to adapt to bags of different specifications, thus meeting the diversity of production requirements and ensuring that the bag is accurately and quickly opened during high - speed production, providing a good foundation for subsequent packaging processes.
