Technical Field
[0001] This utility model relates to the field of sealing device technology, and in particular to an automatic sealing device for warehouse tobacco sealing bags. Background Technology
[0002] When storing tobacco in a warehouse, it needs to be covered and sealed with a bottom film. Currently, the bottom film is rolled up manually and then spread over the box. This operation requires timely operation by the operator. When there are many boxes, the operation is labor-intensive, and it is also difficult when the boxes are placed high. To better solve this problem, we propose an automatic sealing device for warehouse tobacco sealing bags. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic sealing device for warehouse tobacco sealing bags.

[0006] Preferably, a bracket is fixed on the rectangular frame.
[0007] Preferably, the two ends of the cylindrical base are fixedly connected to the rectangular frame by bolts.
[0008] Preferably, the drive mechanism includes a second motor, a gear, and an arc-shaped rack. The second motor is installed in a slot, and the output shaft of the second motor is fixedly sleeved with a gear. The arc-shaped rack is embedded in an arc-shaped push rod, and the arc-shaped rack meshes with the gear for transmission.
[0009] Preferably, a first anti-slip pad is fixed to the end face of the clamping plate, and a second anti-slip pad is fixed inside the groove. Both the first and second anti-slip pads are provided with anti-slip patterns.
[0010] Preferably, both ends of the cylindrical shell are fixed with sliders, and strip grooves are provided on the inner walls of both sides of the rectangular frame, and the sliders are slidably installed in the strip grooves.
[0011] Preferably, two guide rollers are rotatably mounted inside the strip-shaped through hole, and the bottom film is located between the two guide rollers.
[0012] Preferably, an infrared sensor is installed at one end of the cylindrical shell.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In this invention, a rectangular frame is fixed in a designated position by a bracket. A drive mechanism can push an arc-shaped push rod to slide, which in turn pushes a clamping plate to move. One end of the bottom film is fixed in the slot by the clamping plate. After the tobacco leaves are placed, an infrared sensor confirms that the forklift forks have been removed. At this time, the first motor drives the reel to rotate, and the reel continuously releases the bottom film. The bottom film unfolds continuously, while the cylindrical shell descends continuously. When it descends to the bottom, the bottom film is fully unfolded. At this time, the bottom film is placed on the tobacco box, thus completing the sealing operation. When the bottom film needs to be removed, the first motor reverses, and the first motor continuously rewinds the bottom film onto the reel through the reel, thereby realizing the reuse of the bottom film and making the operation very convenient. The first and second anti-slip pads help to better clamp the bottom film. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-4 An automatic sealing device for warehouse tobacco sealing bags includes a rectangular frame 1, which is fixed in a designated position by a bracket 2. A cylindrical base 3 is installed inside the rectangular frame 1. A slot 17 is formed on the side of the cylindrical base 3, and an arc-shaped sliding groove 16 is formed inside the cylindrical base 3. An arc-shaped push rod 8 is slidably sleeved in the arc-shaped sliding groove 16. One end of the arc-shaped push rod 8 is fixed with a clamping plate 18. A drive mechanism 7 for pushing the arc-shaped push rod 8 to slide is installed in the slot 17. The drive mechanism 7 can push the arc-shaped push rod 8 to slide. The curved push rod 8 pushes the clamping plate 18 to move, and one end of the bottom film 9 is fixed in the slot 17 by the clamping plate 18; a cylindrical shell 5 is slidably installed in the rectangular frame 1, and a first motor 12 is installed inside the cylindrical shell 5. The output shaft of the first motor 12 is connected to a roller 13, and the bottom film 9 is wound on the roller 13. A strip-shaped through hole 14 is opened on the side of the cylindrical shell 5, and the bottom film 9 passes through the strip-shaped through hole 14. One end of the bottom film 9 away from the roller 13 is clamped in the slot 17 by the clamping plate 18. A bracket 2 is fixed on the top. The two ends of the cylindrical base 3 are fixedly connected to the rectangular frame 1 by bolts 4. Slider 11 is fixed to both ends of the cylindrical shell 5. Strip grooves 10 are opened on the inner walls of both sides of the rectangular frame 1. The slider 11 is slidably installed in the strip grooves 10. Two guide rollers 15 are rotatably installed in the strip through hole 14. The bottom film 9 is located between the two guide rollers 15. An infrared sensor 6 is installed at one end of the cylindrical shell 5. After the tobacco leaves are placed, the infrared sensor 6 confirms that the forklift forks have been removed. At this time, the first motor 12 drives the roller 13 to rotate. The roller 13 continuously releases the bottom film 9. At this time, the bottom film 9 continuously unfolds. At the same time, the cylindrical shell 5 continuously descends. When it descends to the bottom, the bottom film 9 is fully unfolded. At this time, the bottom film is covered on the tobacco box, and the sealing operation is completed. When it is necessary to remove the bottom film 9, the first motor 12 reverses. The first motor 12 continuously rewinds the bottom film 9 onto the roller 13 through the roller 13, thereby realizing the reuse of the bottom film 9. The operation is very convenient.
[0022] Reference Figure 4The drive mechanism 7 includes a second motor 71, a gear 72, and an arc-shaped rack 73. The second motor 71 is installed in the slot 17, and the output shaft of the second motor 71 is fixedly sleeved with the gear 72. The arc-shaped rack 73 is embedded in the arc-shaped push rod 8, and the arc-shaped rack 73 meshes with the gear 72 for transmission. A first anti-slip pad 19 is fixed on the end face of the clamping plate 18, and a second anti-slip pad 20 is fixed in the slot 17. Both the first anti-slip pad 19 and the second anti-slip pad 20 are provided with anti-slip patterns. The second motor 71 drives the gear 72 to rotate, and the gear 72 pushes the arc-shaped rack 73 to slide in the arc-shaped slide groove 16 through meshing with the arc-shaped rack 73. The first anti-slip pad 19 and the second anti-slip pad 20 help to better clamp the bottom film 9.
[0023] Working principle: The rectangular frame 1 is fixed in the designated position by the bracket 2. The drive mechanism 7 can push the arc-shaped push rod 8 to slide. The arc-shaped push rod 8 pushes the clamping plate 18 to move. One end of the bottom film 9 is fixed in the slot 17 by the clamping plate 18. After the tobacco leaves are placed, the infrared sensor 6 confirms that the forklift forks have been removed. At this time, the first motor 12 drives the reel 13 to rotate. The reel 13 continuously releases the bottom film 9. At this time, the bottom film 9 continuously unfolds. At the same time, the cylindrical shell 5 continuously descends. When it descends to the bottom, the bottom film 9 is fully unfolded. At this time, the bottom film covers the tobacco box, thus completing the sealing operation. When it is necessary to remove the bottom film 9, the first motor 12 reverses. The first motor 12 continuously rewinds the bottom film 9 onto the reel 13 through the reel 13, thereby realizing the reuse of the bottom film 9. The operation is very convenient. The first anti-slip pad 19 and the second anti-slip pad 20 help to better clamp the bottom film 9.
[0024] The operating principle of the drive mechanism 7 is as follows: the second motor 71 drives the gear 72 to rotate, and the gear 72 pushes the arc rack 73 to slide in the arc groove 16 through meshing with the arc rack 73.
