DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below through the accompanying drawings and specific implementation methods.

[0028] Example

[0029] Please refer to Figures 1 to 6 , this embodiment provides a packaging bag taking and sealing device, including a mounting plate 1, a linear guide 2, a slide 3, a reduction motor 4, a vacuum suction cup 501 assembly 5, a bag pressing part 6 and a heat sealing strip 7, the linear guide 2 is arranged on the mounting plate 1; the slide 3 is movably mounted on the linear guide 2; the reduction motor 4 is mounted on the mounting plate 1 and is connected to the slide 3 through a crank mechanism; the crank mechanism is used to convert the rotational motion of the reduction motor 4 into linear motion of the slide 3 on the linear guide 2; the vacuum suction cup 501 assembly 5 is connected to one end of the slide 3; the vacuum suction cup 501 assembly 5 is provided with a vacuum suction cup 501 for grabbing the packaging bag 100 to be taken; the bag pressing part 6 is connected to the other end of the slide 3; the heat sealing strip 7 is arranged on the mounting plate 1 and is located on the path where the bag pressing part 6 moves linearly with the slide 3; the heat sealing strip 7 is used to clamp the bag opening of the packaging bag 200 to be sealed with the bag pressing part 6 for sealing.

[0030] In this embodiment of the packaging bag removal and sealing device, the bag removal station is located on the mounting plate 1, one side of the vacuum suction cup 501 assembly 5, and is located at one end of the linear guide 2. The vacuum suction cup 501 assembly 5 forms the bag gripping mechanism. The sealing station is located on the mounting plate 1, one side of the bag opening press component 6 and heat sealing strip 7, and is located at the other end of the linear guide 2. The bag opening press component 6 and heat sealing strip 7 form the sealing mechanism.

[0031] The packaging bag removal and sealing device of this embodiment, when in use, may include the following steps:

[0032] Place the packaging bag 100 to be taken at the bag taking station;

[0033] Place the packaging bag 200 to be sealed at the sealing station;

[0034] Start the reduction motor 4, and the crank mechanism converts the rotational motion output by the reduction motor 4 into the linear motion of the slide 3 along the linear guide rail 2, so that the slide 3 performs reciprocating linear motion between the bag taking station and the sealing station;

[0035] When the slide 3 moves toward the bag taking station, it drives the vacuum suction cup 501 of the vacuum suction cup assembly 5 to suck the packaging bag 100 to be taken;

[0036] When the slide 3 moves toward the sealing station, the suction cup grabs the packaging bag 100 to be taken and moves it to the next station, so that the packaging bag 100 to be taken becomes the taken packaging bag 101; the next station can be a transport station for transporting the packaging bag to, for example, a bagging station;

[0037] At the same time, when the slide plate 3 moves toward the sealing station, it drives the bag opening pressing component 6 to move toward the heat sealing strip 7, so that the bag opening pressing component 6 and the heat sealing strip 7 clamp the bag opening of the packaging bag 200 to be sealed for sealing.

[0038] The packaging bag taking and sealing device of this embodiment can simultaneously realize the bag taking operation of the packaging bag 100 to be taken and the sealing operation of the packaging bag 200 to be sealed through a reduction motor 4, thereby avoiding the use of multiple motors, simplifying the workstation structure, reducing the occupied space, reducing costs and improving efficiency.

[0039] Specifically, the linear guide rail 2 is fixedly connected to the mounting plate 1. The packaging bag 100 to be removed and the packaging bag 200 to be sealed are conventional vertical rigid packaging bags. The vacuum suction cup 501 is controlled by a PLC controller to suck and release the packaging bag 200 to be sealed. Both the vacuum suction cup 501 and its PLC controller are conventional products. The packaging bag 200 to be sealed contains material. The bag opening pressing component 6 can be a conventional product capable of clamping the bag opening with the heat sealing strip 7 to seal the bag.

[0040] Please refer to Figure 1 、 Figure 2 and Figures 4 to 6 The vacuum suction cup 501 assembly 5 includes a first connecting frame 502 and a vacuum suction cup 501 . The vacuum suction cup 501 is connected to the first connecting frame 502 , and the first connecting frame 502 is connected to one end of the slide 3 .

[0041] Please refer to Figure 1 、 Figure 5 and Figure 6 The bag opening pressing component 6 includes a second connecting frame 602 and a pressing block 601. The pressing block 601 is connected to the second connecting frame 602, which is connected to the other end of the slide 3. The pressing block 601 is used to clamp the bag opening of the packaging bag 200 with the heat sealing strip 7 to seal it. A spring 603 can be connected between the pressing block 601 and the second connecting frame 602 to facilitate the pressing of the bag opening with the heat sealing strip 7.

[0042] The bag-removing station and the sealing station are located in the two directions of the linear motion of the slide 3. The heat-sealing strip 7 is connected to the mounting plate 1 and is located in the path of the bag-opening pressing member 6 as it moves toward the sealing station; that is, the distance between the bag-opening pressing member 6 and the heat-sealing strip 7 decreases as it moves toward the sealing station.

[0043] like Figure 3 As shown, in some embodiments, the slide 3 is provided with a guide groove 8, and the crank mechanism includes a cam 9 and a connecting rod 10; one end of the cam 9 is connected to the rotating output shaft of the reduction motor 4, and the other end is connected to one end of the connecting rod 10, and the other end of the connecting rod 10 is movably set in the guide groove 8.

[0044] The reduction motor 4 drives the cam 9 to rotate, and the cam 9 drives the connecting rod 10 to move in the guide groove 8. At the same time, the connecting rod 10 drives the slide plate 3 to move along the linear guide rail 2.

[0045] Specifically, the guide groove 8 is configured as a rectangular strip, and the length direction of the guide groove 8 is perpendicular to the length direction of the linear guide rail 2. The cam 9 drives the connecting rod 10 and the slide 3 to move along the linear guide rail 2. At the same time, the connecting rod 10 moves perpendicularly to the linear guide rail 2 in the guide groove 8.

[0046] In some embodiments, a bearing 11 is provided at the other end of the connecting rod 10 , and the bearing 11 is rotatably disposed in the guide groove 8 .

[0047] By rotating the bearing 11 in the guide groove 8, the connecting rod 10 can move perpendicularly to the linear guide rail 2 in the guide groove 8 more smoothly, which is beneficial for the connecting rod 10 to drive the slide plate 3 to move along the linear guide rail 2 under the rotation of the cam 9.

[0048] Please refer to Figure 1 、 Figure 5 and Figure 6 Specifically, the mechanical origin position of the slide 3 is set to the position where the vacuum suction cup 501 presses against the packaging bag 100 to be taken. The reduction motor 4 rotates in one direction when working. After the PLC controller gives a bag-taking signal, the vacuum suction cup 501 sucks the packaging bag 100 to be taken, and the reduction motor 4 starts to rotate, pushing the slide 3 to the side of the sealing station through the bearing 11; the slide 3 drives the bag-opening pressing component 6 to squeeze the bag opening of the packaging bag 200 containing the material to be sealed to the heat sealing strip 7; at this time, the vacuum suction cup 501 releases the packaging bag 100 to be taken and sends it to the next station. At this time, the packaging bag 100 to be taken becomes the taken packaging bag 101 and waits for subsequent processing in the next station; at the same time, the heat sealing strip 7 is energized and heated. After the bag opening of the packaging bag 200 to be sealed is squeezed, heat-sealed and shaped, the reduction motor 4 rotates until the slide 3 returns to the mechanical origin, waiting for the next bag-taking and heat-sealing operation.

[0049] like Figure 3 As shown, in some embodiments, an inverted U-shaped guide groove plate 12 is connected to the slide plate 3, and a gap is set between the top wall of the guide groove plate 12 and the slide plate 3; the guide groove 8 is set as a through hole and is opened on the top wall of the guide groove plate 12.

[0050] By providing a through-hole guide groove 8 on the guide groove plate 12, it is possible to facilitate the placement of the connecting rod 10 or its bearing 11 in the guide groove 8, thereby preventing the connecting rod 10 or its bearing 11 from sliding out of the guide groove 8. By providing a gap between the top wall of the guide groove plate 12 and the slide plate 3, it is helpful to increase the vertical length of the connecting rod 10 or its bearing 11 in the guide groove 8, thereby improving the reliability and stability of the connecting rod 10 or its bearing 11 in the guide groove 8, and further preventing the connecting rod 10 or its bearing 11 from sliding out of the guide groove 8.

[0051] Specifically, the bottoms of both side walls of the inverted U-shaped guide groove plate 12 are connected to both sides of the slide plate 3 respectively.

[0052] Please refer to Figure 1 、 Figures 3 to 6 In some embodiments, the linear guide 1 and the reduction motor 3 are installed on the upper surface of the mounting plate 1, and the vacuum suction cup 501 assembly 4 is arranged above the mounting plate 1; a through-hole connecting slot 13 is opened on the mounting plate 12, and the bottom of the other end of the slide plate 3 passes through the connecting slot 13 and extends to the bottom of the mounting plate 1; the bag pressing mouth component 5 is arranged below the mounting plate 12, and the heat sealing strip 6 is installed on the lower surface of the mounting plate 1.

[0053] By arranging the bag grabbing mechanism and the sealing mechanism above and below the mounting plate 1 respectively, interference between the bag grabbing mechanism and the sealing mechanism during installation and use can be avoided, which is beneficial to the safe installation and use of the entire device.

[0054] Specifically, the mounting plate 1 is connected to the bracket so that there is a height distance between the mounting plate 1 and the ground or table below, so that the sealing mechanism can be arranged within the height distance.

[0055] The bracket may include four legs, which may be distributed in a rectangular shape. The mounting plate 1 may be connected to the tops of the four legs.

[0056] like Figure 4 As shown, it can also be specifically provided that two connecting notches 13 are provided, and are respectively provided on both sides of the linear guide rail 2 .

[0057] like Figure 3 As shown, the slide plate 3 is provided with an inverted U-shaped plate, and the linear guide rail 2 is provided in the inverted U-shaped groove of the slide plate 3 .

[0058] Please refer to Figure 1 、 Figure 5 and Figure 6 The bottoms on both sides of the slide plate 3 pass through two connecting notches 13 respectively. The bag pressing opening component 6 is connected to the bottom of the other end of the slide plate 3. The heat sealing strip 6 is connected to the lower surface of the mounting plate 1.

[0059] Please refer to Figures 2 to 4 and Figure 6In some embodiments, the mounting plate 1 is provided with a through-hole lower bag notch 14 , and the lower bag notch 14 is arranged on the path where the vacuum suction cup 501 assembly 5 moves linearly with the slide plate 3 .

[0060] Please refer to Figures 1 to 4 and Figure 6 After the vacuum suction cup 501 of the vacuum suction cup assembly 5 grabs the packaging bag 100 to be taken, it moves linearly under the drive of the slide 3; when passing through the lower bag slot 14, the vacuum suction cup 501 can release the packaging bag 100 to be taken, so that the packaging bag 100 to be taken falls through the lower bag slot 14 to enter the next workstation.

[0061] Please refer to Figure 1 、 Figures 4 to 6 In some embodiments, the number of vacuum suction cups 501 is at least two, and the at least two vacuum suction cups 501 are distributed from top to bottom.

[0062] The packaging bag 100 to be taken can be firmly grasped by multiple vacuum suction cups 501. By providing at least two vacuum suction cups 501 distributed vertically among the multiple vacuum suction cups 501, the upper and lower parts of the packaging bag 100 to be taken can be grasped respectively, further ensuring that the packaging bag 100 to be taken is firmly grasped.

[0063] In some embodiments, the heat sealing strip 7 is connected to a heater. The heater can heat the heat sealing strip 7 so that the glue on the heat sealing strip 7 adheres to the bag opening of the packaging bag 200 to be sealed, thereby achieving sealing.

[0064] Specifically, the heat sealing strip 7 can be mounted on a mounting assembly, the mounting assembly can be connected to the mounting plate 1, and the heater can be mounted on the mounting assembly.
