The direction of movement of the package 30 is shown by an arrow in the figure, and the package sealing device is divided into a front portion for making a package with a single side opening and a rear portion for sealing the package with the product. Specifically, the first pressing member 1 is connected to a cylinder and a roller, and the packaging bag raw material is pressed to a preset position by the first pressing member 1, and the first pressing member 1 is normally pressed when opened, in addition, the hot knife 2 is arranged in front of the first pressing member 1 along the moving direction of the packaging bag 30, and the hot knife 2 is a knife for cutting objects after heating, therefore, when the packaging bag raw material moves to the preset position, the packaging bag 30 is melted by pressurizing and heating the packaging bag 30, and the first cutting assembly 3 comprises a first thin belt guide rod cylinder 31 electrically connected with a main control system, and a first rubber roller 32 connected with a telescopic rod of the first thin belt guide rod cylinder 31, when the packaging bag raw material moves to the preset position, the main control system opens the hot knife 2 and the first cutting assembly 3, the first thin belt guide rod cylinder 31 drives the first rubber roller 32 to move towards one side of the first conveying belt until the first rubber roller abuts against the packaging bag 30, and the first rubber roller 32 and the moving first conveying assembly 5 jointly act to separate the packaging bag raw material from two sides of the packaging bag 30 when the packaging bag raw material is pressurized and heated at the sealing position of the packaging bag 30.
Further, in the present embodiment, as shown in fig. 2 and 4, the package 30 sealed at both sides is continuously conveyed forward by the first conveying means 5 until the package 30 moves to the second cutting means 4. The second cutting assembly 4 includes a second thin belt guide cylinder 43 electrically connected to the main control system, and a second glue roller 44 connected to the second thin belt guide cylinder 43. The second cutting assembly 4 comprises a thin air cylinder 41 electrically connected with the main control system and a cold cutter 42 connected with a telescopic rod of the thin air cylinder 41. When the packaging bag 30 moves to the preset position of the second cutting assembly 4, the main control system opens the second thin belt guide rod cylinder 43 to drive the second rubber covered roller 44 to move towards one side of the packaging bag 30, the packaging bag 30 is pressed at the preset position through the second rubber covered roller 44, the main control system opens the thin cylinder 41 to drive the cold cutter 42 to move, and the sealing area at the front end of the packaging bag 30 is cut off by the cold cutter 42, so that the packaging bag 30 with one sealed end is obtained.
Next, as shown in fig. 8 to 11, the packaging bag 30 with one open end is continuously conveyed forward by the second conveying member 7, and at the same time, the product is loaded into the packaging bag 30 with one open end, and after the product is loaded, the packaging bag is continuously conveyed forward to the corresponding position of the second pressing member 6. The second pressing piece 6 includes an air cylinder 61, an upper sealing plate 62, a lower sealing plate 63 and heating wires, the air cylinder 61 is electrically connected with the main control system and is connected with the upper sealing plate 62, the upper sealing plate 62 is opposite to the lower sealing plate 63, and the heating wires are respectively arranged on one side of the upper sealing plate 62 opposite to the lower sealing plate 63. In addition, in the present embodiment, the second pressing member 6 may further include an upper mounting plate 65, a linear bearing 67 disposed on the lower mounting plate 66 opposite to the upper mounting plate 65 and connecting the upper mounting plate 65 and the lower mounting plate 66, wherein the upper sealing plate 62 and the air cylinder 61 may be disposed on both sides of the upper mounting plate 65, respectively, and the upper mounting plate 65 may be driven to perform linear movement along the axial direction of the linear bearing 67 by the linear bearing 67, so that the upper mounting plate 65 gradually approaches or gets away from the lower mounting plate 66.
In addition, in the present embodiment, the edge tearing assembly 8 includes an upper edge tearing roller 81, a lower edge tearing roller 82 provided opposite to the upper edge tearing roller 81, and a rotary cylinder 83 electrically connected to the main control system. The rotary cylinder 83 is a cylinder which is fixed to the air inlet and outlet pipes and the air guide head, and the rotary cylinder body can rotate relatively and acts on the lower edge tearing roller 82, and mainly comprises the air guide head, a cylinder body, a piston and a piston rod. When the rotary cylinder 83 works, the external force drives the cylinder body, the cylinder cover and the air guide head to rotate, the piston and the piston rod can only do reciprocating linear motion, and the air guide head is externally connected with a pipeline and is fixed. Specifically, the upper edge tearing roller 81 is disposed on one side of the upper sealing plate 62 far away from the first cutting assembly 3, and the lower edge tearing roller 82 is connected with the rotary cylinder 83, and the rotary cylinder 83 drives the lower edge tearing roller 82 to perform rotary motion, so that relative rotation is formed between the upper edge tearing roller 81 and the lower edge tearing roller 82. Therefore, when the packaging bag 30 moves to a preset position, the main control system controls the servo motor to work, and the servo motor drives the linear bearing 67 to move up and down along the axial direction of the optical axis 9 through a connecting rod mechanism, so as to drive the upper sealing plate 62 to move towards one side of the lower sealing plate 63, fix the packaging bag 30 between the upper sealing plate 62 and the lower sealing plate 63, heat the sealing position of the packaging bag 30 through the heating wire, and melt the packaging bag 30, and simultaneously, the main control system opens the rotary cylinder 83 to drive the upper edge tearing roller 81 and the lower edge tearing roller 82 to rotate relatively. So that the outer side of the sealing part of the packaging bag 30 is torn off by the upper edge tearing roller 81 and the lower edge tearing roller 82 together in the molten state of the packaging bag 30 to form a packaging finished product. In actual use, the heating wires may be provided only on the upper sealing plate 62 or only on the lower sealing plate 63. In addition, the upper edge tearing roller 81 can also rotate simultaneously with the lower edge tearing roller 82, and when the upper edge tearing roller 81 and the lower edge tearing roller 82 rotate simultaneously, the rotation direction of the upper edge tearing roller 81 is opposite to the rotation direction of the lower edge tearing roller 82. Therefore, the two sides of the manufactured packaging finished product have no redundant ears, the boxing difficulty of the packaging finished product is greatly reduced, and the packaging finished product is more attractive. In the actual use process, the link mechanism may be a four-link mechanism or other link mechanisms, as long as the linear bearing 67 can be driven to move up and down along the axis direction of the optical axis 9.
In the present embodiment, as shown in fig. 2, 3, and 4, a belt conveyor may be used for both the first conveying unit 5 and the second conveying unit 7.

It is clear from the above that, when the package sealing device seals the package 30, the hot knife 2 heats the package material under pressure, and the first cutting assembly 3 and the first conveying assembly 5 cooperate to convey the package 30, and the package 30 is easily torn in a partially melted state, so that when the hot knife 2 melts and cuts the package material, the package 30 can be separated from the package material by the first cutting assembly 3 and the first conveying assembly 5, and thus, no ears are present at the seal of the package 30, and the package 30 with both ends sealed is formed. When the first conveying component 5 conveys the packaging bags 30 with sealed two ends to the position of the second cutting component 4, the main control system controls the second cutting component 4 to cut off the sealing area at the front end of the packaging bags 30 to form packaging bags 30 with sealed one ends, and products are filled into the packaging bags 30 through the opening. When the product is put into the packaging belt, the front end opening of the packaging bag 30 is pressed and heated by the second pressing member 6, and the part except the sealing of the packaging bag 30 is torn off by the tearing edge assembly 8. Therefore, ears do not exist on two sides of the packaging bag 30, the packaging bag is greatly convenient for packaging packaged products, and meanwhile, the packaged finished products are more attractive.
It should be noted that, in this embodiment, as shown in fig. 8, in order to automatically cut the packaging bag 30 and ensure uniformity of the packaging bag 30, a plurality of color codes are further disposed on the packaging bag raw material, wherein a portion between any two adjacent color codes is a length required by one packaging bag 30, and a distance between any two adjacent color codes is equal. Correspondingly, a first photoelectric switch is further arranged on the first pressing piece 1, a second photoelectric switch is arranged at the second cutting-off assembly 4, and the first photoelectric switch and the second photoelectric switch are respectively used for detecting color codes on the packaging bag 30. Specifically, when the first photoelectric switch detects the color code on the packaging bag 30, the main control system opens the first cutting assembly 3 and the hot cutter 2 to press the packaging bag 30 at a preset position so as to form the packaging bag 30 with two sealed ends; when the second photoelectric switch detects the color code on the packaging bag 30, the main control system opens the second cutting assembly 4, and the second cutting assembly 4 cuts off one end seal of the packaging bag 30 to form a packaging bag with one open end.
In order to facilitate recycling of the portion cut from the packaging bag 30, as shown in fig. 4 and 8, the packaging bag sealing device may further include a first waste sucker 10 and a second waste sucker 20, wherein the first waste sucker 10 is disposed below the second cutting assembly 4 and between the first conveying assembly 5 and the second conveying assembly 7, and when the front end sealing portion of the packaging bag 30 is cut by the second cutting assembly 4, the waste can directly fall into the first waste sucker 10, so that the waste cut by the second cutting assembly 4 can be prevented from falling into a production workshop and polluting the working environment. Likewise, the second waste sucker 20 may be disposed below the lower mounting plate 66, specifically, a waste sucker may be disposed on the lower mounting plate 66 and connected to the second waste sucker 20, and when the second pressing member 6 and the edge tearing assembly 8 jointly cut off the redundant material at the front end sealing position of the packaging bag 30, the redundant material may be conveyed to the second waste sucker 20 through the waste sucker, so as to avoid the waste falling into the production workshop, and thus avoid affecting the environment of the production workshop.
