[0029] Driving assembly 40 includes top plate 41, guide rod 42, moving block 43, mounting plate 44, one-way lead screw 45 and first motor 46.The top plate 41 is arranged above the limiting ring 22 and is fixedly connected with the base 31 by a connecting column 47.The guide rod 42 is arranged in the transverse direction and is fixedly connected with the top plate 41.The moving block 43 is arranged on the guide rod 42 and is slidably connected with the guide rod 42.The mounting plate 44 is arranged below the moving block and is fixedly connected with the moving block by a connecting block.The one-way lead screw 45 passes through the moving block 43 in the transverse direction, and both ends are rotatably connected with the top plate 41.The one-way lead screw 45 is threadedly connected with the moving block 43.The first motor 46 is fixedly installed on the top plate 41 and is electrically connected with the control cabinet, and the first motor 46 is used to control the rotation of the one-way lead screw 45.

[0030] Heat sealing assembly 50 includes guide rail 51, two-way lead screw 52, second motor 53 and two sliding blocks 54.The guide rail 51 is fixedly installed at the bottom of the mounting plate 44 in the transverse direction.The two-way lead screw 52 is arranged in the transverse direction, and both ends are rotatably connected with the mounting plate 44, and the screw direction of both ends of the two-way lead screw 52 is opposite.The second motor 53 is fixedly installed on the mounting plate 44 and is electrically connected with the control cabinet, and the second motor 53 is used to control the rotation of the two-way lead screw 52.Two sliding blocks 54 are arranged at both ends of the two-way lead screw 52 and are threadedly connected with the two-way lead screw 52.A heat sealing plate 55 is fixedly installed on the sliding block 54, and the heat sealing plate 55 is electrically connected with the control cabinet.

[0031] In the initial state, the staff places the coated kraft paper in the concave shape in the limiting ring 22, and loads the material or product into the concave part of the coated kraft paper.The control cabinet controls the heat sealing plate 55 to start and preheat to 140℃.

[0032] The specific working process of the equipment is as follows:

[0033] Firstly, the control cabinet controls the belt conveyor to start, and the conveyor belt 12 drives the limiting ring 22 and the kraft paper to the two sliders 54 of the heat sealing assembly 50.

[0034] Then, the control cabinet controls the second motor 53 to start, and the second motor 53 drives the bidirectional screw rod 52 to rotate, and under the action of the guide rail 51, the two sliders 54 drive the two heat sealing plates 55 to move close to each other until the two heat sealing plates 55 clamp the port of the kraft paper. At the same time, the control cabinet controls the first motor 46 to start, and the first motor 46 drives the unidirectional screw rod 45 to rotate, and under the action of the guide rod 42, the moving block 43 drives the mounting plate 44 to move outward, and because of the clamping of the two heat sealing plates 55, the kraft paper will be separated from the limiting ring 22 and moved out of the device with the mounting plate 44. In the process of clamping and moving the kraft paper, the kraft paper will be clamped and heat sealed, which improves the work efficiency.

[0035] Finally, the control cabinet controls the second motor 53 to drive the bidirectional screw rod 52 to flip, and under the action of the guide rail 51, the two sliders 54 drive the two heat sealing plates 55 to move away from each other, and the heat sealed kraft paper will automatically fall into the receiving box 32. Then the control cabinet controls each part to reset.

[0036] The whole process does not need manual intervention and can automatically heat seal the kraft paper.

[0037] In an embodiment, the heat sealing plates 55 are located below the limiting ring 22. In this way, when the two heat sealing plates 55 move close to each other, they can better clamp the port of the kraft paper, avoiding the failure of heat sealing due to the slipping between the kraft paper and the heat sealing plates 55.

[0038] In an embodiment, the number of heat sealing assemblies 50 is two, and the two heat sealing assemblies 50 are arranged on the two sides of the mounting plate 44.

[0039] This design enables the two heat sealing assemblies 50 to work alternately when the driving assembly 40 is working, that is, when one heat sealing assembly 50 clamps the port of the kraft paper, the other heat sealing assembly 50 releases the heat sealed kraft paper to automatically fall into the receiving box 32, further improving the work efficiency of the device.

[0040] In an embodiment, the number of receiving assemblies 30 is two, and the two receiving assemblies 30 are arranged on the two sides of the belt conveyor and correspond to the two heat sealing assemblies 50.

[0041] The two receiving assemblies 30 are respectively used to receive the kraft paper heat sealed by the corresponding heat sealing assembly 50.

[0042] In one embodiment, the top of the base 31 is provided with a limiting groove 33 extending downward. The bottom of the limiting groove 33 is fixedly provided with a pressure sensor 34, which is electrically connected with the control cabinet. The limiting groove 33 is provided with a lifting plate 35, which is in sliding contact with the inner wall of the limiting groove 33. The limiting groove 33 is provided with a spring 36, the first end of which is fixedly connected with the lifting plate 35, and the second end of which is fixedly connected with the bottom of the limiting groove 33. The receiving box 32 is placed on the top of the lifting plate 35.

[0043] With the operation of the device, the heat-sealed coated kraft paper in the receiving box 32 increases, and the receiving box 32 and the lifting plate 35 move downward under the action of gravity, and the spring 36 is compressed until the lifting plate 35 contacts the pressure sensor 34. The pressure sensor 34 sends a signal to the control cabinet, and the control cabinet controls the device to stop running and reminds the staff to replace the receiving box 32 in time.

[0044] In one embodiment, an opening is formed between the limiting groove 33 and the outer side of the base 31, which further facilitates the staff to take out and replace the receiving box 32.

[0045] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application.
