DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5A plastic bag sealing and pressing mechanism comprises a sealing and pressing mechanism 1, an edge sealing device 2 and an edge sealing platform 3 are arranged on the sealing and pressing mechanism 1, a base 4 is installed at the bottom of the sealing and pressing mechanism 1, a first support block 5 and a second support block 6 are installed on the base 4, a first conveying roller 7 is rotatably installed in the first support block 5, a second conveying roller 9 is rotatably installed in the second support block 6, a conveyor belt 8 is movably installed on the first conveying roller 7 and the second conveying roller 9, a protective shell 12 is installed on the base 4, a motor 13 is installed in the protective shell 12, a transmission shaft 14 is installed on the motor 13, a half gear 15 is installed on the transmission shaft 14, a gear 16 is meshed on the half gear 15, and the gear 16 is installed on the second conveying roller 9 At one end, a support plate 19 is installed on the base 4, and the support plate 19 is located in the conveyor belt 8. A placement box 18 is installed on the outer wall of the protective shell 12, and a positioning groove 11 is opened on the placement box 18. A fixing plate 24 is installed on the edge sealing device 2, and a friction pad 25 is installed at the bottom of the fixing plate 24. First, the plastic bag to be sealed is placed in the placement box 18, and then the plastic bags are taken out in turn and one side of the plastic bag is placed on the positioning groove 11 to position the plastic bag. At this time, the position where the plastic bag needs to be sealed is just on the same horizontal line as the edge sealing device 2 and the edge sealing table 3. At this time, the motor 13 is started, and the rotation of the motor 13 drives the transmission shaft 14 to rotate, and the rotation of the transmission shaft 14 drives the semi-gear 15 The rotation of the half gear 15 drives the gear 16 to rotate, and the rotation of the gear 16 drives the second conveying roller 9 to rotate. The rotation of the second conveying roller 9 drives the conveyor belt 8 to convey, and the plastic bag to be sealed on the conveyor belt 8 will move between the edge sealing device 2 and the edge sealing table 3 under the transportation of the conveyor belt 8. When the plastic bag is in the position to be sealed, the half gear 15 and the gear 16 are no longer meshed, and the rotation of the half gear 15 will not drive the gear 16 to rotate, thereby stopping the conveyor belt 8 from conveying. At this time, the sealing clamping mechanism 1 can be started, and the plastic bag is pressed and sealed by the edge sealing device 2 and the edge sealing table 3. In the process of pressing and sealing the edge sealing device 2, the fixed plate 24 will be driven to descend and the plastic bag to be sealed will be moved to the edge sealing device 2 and the edge sealing table 3. The plastic bag is pressed down to prevent the plastic bag from tilting up during the sealing process of the plastic bag. The friction pad 25 is set to increase the friction during contact. After the plastic bag is sealed, the half gear 15 and the gear 16 will mesh again. At this time, through the conveying action of the conveyor belt 8, the sealed plastic bag will enter the collection box 21 through the collection port 20 for collection. At this time, the next plastic bag to be sealed will enter the sealing position again and be sealed by the edge sealing device 2 and the edge sealing table 3. By repeating the above process, more plastic bags can be sealed. There is no need for the operator to fix and place the plastic bag on the edge sealing device 2. The degree of automation is high, which saves the time of plastic bag packaging.

[0023] Further, two limiting rings 10 are installed on the outer wall of the second conveying roller 9, and the two limiting rings 10 are respectively distributed on both sides of the conveying belt 8. Through the setting of the two limiting rings 10, the conveying belt 8 can be limited to prevent the conveying belt 8 from moving on the second conveying roller 9.

[0024] Furthermore, a third support block 17 is installed in the protective shell 12, and the transmission shaft 14 is rotatably installed in the third support block 17. The third support block 17 can play a supporting role for the transmission shaft 14.

[0025] Furthermore, a collecting port 20 is provided on the base 4, and the collecting port 20 is in a square shape. A collecting box 21 is installed at the bottom of the base 4, and the collecting box 21 is located below the collecting port 20. Through the conveying action of the conveyor belt 8, the sealed plastic bags will pass through the collecting port 20 and enter the collecting box 21 for collection.

[0026] Further, a cover plate 22 is detachably mounted on the protective shell 12, and a buckle 23 is mounted on the cover plate 22, and the buckle 23 is snapped on the protective shell 12. By opening the buckle 23, the cover plate 22 on the protective shell 12 can be opened, so that the mechanism in the protective shell 12 can be easily inspected.

[0027] Furthermore, the thickness of the friction pad 25 ranges from one centimeter to two centimeters, and the material of the friction pad 25 is a rubber material. The friction resistance of the rubber material is relatively large, which meets the use requirements of the friction pad 25.

[0028] The working principle of the utility model is as follows: first, the plastic bag to be sealed is placed in the placement box 18, and then the plastic bags are taken out in turn and one side of the plastic bag is placed against the positioning groove 11 to position the plastic bag. At this time, the position of the plastic bag that needs to be sealed is just on the same horizontal line as the edge sealing device 2 and the edge sealing table 3. At this time, the motor 13 is started, and the rotation of the motor 13 drives the transmission shaft 14 to rotate, and the rotation of the transmission shaft 14 drives the half gear 15 to rotate, and the rotation of the half gear 15 drives the gear 16 to rotate, and the rotation of the gear 16 drives the second conveying roller 9 to rotate, and the rotation of the second conveying roller 9 will drive the conveyor belt 8 to convey, and the plastic bag to be sealed on the conveyor belt 8 will move between the edge sealing device 2 and the edge sealing table 3 under the conveyance of the conveyor belt 8. When the plastic bag is in the position to be sealed, the half gear 15 and the gear 16 are no longer meshed, and the rotation of the half gear 15 will not drive the gear 16 to rotate, thereby preventing the conveyor belt 8 from advancing The plastic bag is then conveyed and the sealing and pressing mechanism 1 can be started. The edge sealing device 2 and the edge sealing table 3 can be used to press and seal the plastic bag. During the pressing and sealing process of the edge sealing device 2, the fixing plate 24 will be driven to descend and press the plastic bag to be sealed to prevent the plastic bag from tilting during the sealing process. The friction pad 25 can be set to increase the friction during contact. After the plastic bag is sealed, the half gear 15 and the gear 16 will mesh again. At this time, through the conveying action of the conveyor belt 8, the sealed plastic bag will enter the collection box 21 through the collection port 20 for collection. At this time, the next plastic bag to be sealed will enter the sealing position again and be sealed by the edge sealing device 2 and the edge sealing table 3. By repeating the above process, more plastic bags can be sealed. There is no need for the operator to fix and place the plastic bag on the edge sealing device 2. The degree of automation is high, which saves the time for plastic bag packaging.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
