DETAILED DESCRIPTION

[0017] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 4 A small sealing machine trimming structure is given, including a sealing machine main body 1 and a sealing machine pressure plate 2 movably connected to the sealing machine main body 1. It is characterized in that the sealing machine main body 1 is provided with a heating strip 3, which is used to heat the plastic product. After the temperature reaches a certain level, the plastic product is plastic-sealed. The sealing machine pressure plate 2 is provided with a pressing groove 4 used in conjunction with the heating strip 3. The pressing groove 4 prevents the temperature of the heating strip 3 from spreading out, and at the same time increases the plastic sealing area of ​​the plastic product. The sealing machine main body 1 is provided with a temperature control knob 5, which is used to adjust the temperature of the heating strip 3 so that the heating strip 3 can be suitable for plastic products of different thicknesses.

[0019] A trimming structure is provided in the sealing machine body 1, which is used to cut the outer area of ​​the plastic sealing mouth while plastic sealing the plastic product. The trimming structure includes a trimming groove 6 provided on the sealing machine body 1, a slider 7 located in the trimming groove 6 and slidably connected thereto, a cutter 8 provided on the slider 7, and a baffle 9 provided on the sealing machine pressure plate 2 and inserted into the trimming groove 6. The baffle 9 supports the plastic product, and the cutter 8 cuts the plastic product on the baffle 9. The cutter 8 and the baffle 9 are used in conjunction with each other.

[0020] A bidirectional lead screw 10 arranged parallel to the heating strip 3 is rotatably connected in the trimming groove 6, and the slider 7 is threadedly connected to the bidirectional lead screw 10. A motor 11 is fixedly connected to the sealing machine body 1, and the output shaft of the motor 11 is fixedly connected to the bidirectional lead screw 10. The motor 11 adopts a servo motor 11, and the servo motor 11 can set the stroke of the motor 11. At the same time, under the action of the bidirectional lead screw 10, a stroke of the servo motor 11 causes the slider 7 to move back and forth, thereby reciprocatingly cutting the plastic product on the baffle 9.

[0021] The bidirectional lead screw 10 is a prior art and can automatically drive the slider 7 thereon to move back and forth without changing the direction of rotation.

[0022] The servo motor 11 is a conventional technology and can realize forward and reverse rotation of the output shaft.

[0023] A positioning post 12 is slidably connected to the slider 7, and the cutter 8 is rotatably connected to the positioning post 12. A concave track groove 13 with the notch facing the slider 7 is opened in the trimming groove 6. The rotating shaft of the cutter 8 is inserted into the track groove 13. Under the action of the track groove 13, the cutter 8 does not contact the baffle 9 at the beginning. After moving for a period of time, the cutter 8 contacts the baffle 9 and cuts the plastic products thereon.

[0024] The sealing machine pressing plate 2 is provided with a button 14 electrically connected to the motor 11. The button 14 controls the motor 11. When the plastic product is plastic-sealed, the motor 11 is started by pressing the button 14.

[0025] When the present invention is in use, the staff opens the sealing machine pressure plate 2 and places the plastic product on the sealing machine body 1. The position to be plastic-sealed is located at the heating strip 3. The staff presses down the sealing machine pressure plate 2, and the pressing groove 4 presses the heating strip 3. At the same time, the baffle 9 presses the plastic product on one side of the plastic-sealed mouth, so that the plastic product on one side of the plastic-sealed mouth is located in the trimming groove 6. After placement, the staff presses the button 14 and the motor 11 starts, so that the cutter 8 moves back and forth, thereby trimming the plastic product. After trimming is completed, the sealing machine pressure plate 2 is swung upward, and the cut waste is removed from the opening of the trimming groove 6.

[0026] The utility model has the advantages of simple structure, convenient operation, novel concept and strong practicality. In the process of plastic sealing the plastic product, the plastic product on one side of the plastic sealing part of the plastic product can be cut at the same time, thereby ensuring that there is a buffer at the plastic sealing part during the plastic sealing process to prevent the plastic sealing part from falling off, and no manual cutting of the plastic product is required, which improves the work efficiency of the staff. The setting of the pressing groove is convenient for pressing the heating strip and keeping it warm at the same time, which can better plastic seal the plastic product. The setting of the track groove is convenient for the cutter to contact the plastic product from one side when cutting the plastic product, which can better cut the plastic product.
