Description

Technical Field

[0001] The present invention relates to the field of vacuum packaging, and particularly to a vacuum packaging device for dental scarf paper.

Background Art

[0002] When packaging existing dental scarf paper, vacuum packaging is generally not used, and it is simply packaged in the normal state. However, in terms of packing and transportation, due to its large volume, it occupies a large space, thus wasting costs. Although vacuum packaging is adopted, the method used is air extraction, which will cause wrinkles in the dental scarf paper. In the case of long-term wrinkles, the dental scarf paper will be deformed, resulting in quality problems, thus affecting the use and also reducing the production efficiency of the enterprise. In order to solve the existing technical problems, the present invention proposes a vacuum packaging device for dental scarf paper.

Summary of the Invention

[0003] The purpose of the present invention is to solve the problems that the dental scarf paper has a large volume and occupies a large space during ordinary packaging, thus wasting costs, and that the air extraction method will cause wrinkles in the dental scarf paper.

[0004] In view of the above problems, the present invention proposes a vacuum packaging device for dental scarf paper, which includes a distribution box, a support frame, a large cylinder, a small cylinder, a lifting frame, a connecting plate, a pressing block, a heating strip, a bracket, a servo motor, a lead screw, a positioning block and a working panel. The distribution box is provided with an operating platform, a PLC control system, an installation groove and a guiding groove. The support frame is installed on the distribution box by welding. The large cylinder is installed on the top of the support frame. The large cylinder is connected to the lifting frame by bolts. Guide columns are also provided on the support frame at both ends of the large cylinder. The guide columns pass through the support frame and are connected to the lifting frame. A flat plate is provided at the bottom of the lifting frame. The flat plate is installed on the lifting frame by welding. The small cylinder is connected to the lifting frame by a connecting plate through bolts. The connecting plate is installed on the lifting frame by bolts. The small cylinder is fixedly connected to the connecting plate, and the connecting plate is fixedly connected to the pressing block. The working panel is fixed on the cushion block. T-shaped grooves are also provided at both ends of the working panel. The bracket is installed on both sides of the distribution box by screws. The servo motor is installed on the bracket. The positioning block is provided with a convex block. The positioning block is placed in the guiding groove on the distribution box through the convex block and is threadedly connected to the lead screw. One end of the lead screw is connected to the servo motor.

[0005] Preferably, the heating strip is installed in the installation groove on the distribution box, and an insulating cloth is also laid on the heating strip.

[0006] Preferably, brackets, servo motors and lead screws are provided on both sides of the distribution box.

[0007] Preferably, a rear stop is also horizontally installed on the working panel. The rear stop is in contact with one end of the positioning block, and an elastic pad is further provided outside the positioning block, and the elastic pad is buckled on the positioning block.

[0008] The structure of the present invention is simple. It uses the extrusion method to expel air, and directly seals the packaging bag by hot melting after extrusion. This method will not wrinkle the dental scarf paper in the packaging bag, and reduces the volume, which is convenient for packaging and transportation, and occupies less space when packing in a box. The positioning blocks on both sides are also set to be movable, and the position of the positioning block can be changed at any time according to the size of the dental scarf paper.

[0016] During the use of the present invention, the working parameters are first set and then the work is carried out; first, the preliminarily packaged dental scarf paper is placed in the middle of the positioning block 9, with the opening of the packaging bag facing outwards, and then the solenoid valve is controlled through the PLC control system 4, and the solenoid valve controls the large cylinder 5 to push the cylinder rod to push the lifting frame 8 to move downward, and the dental scarf paper is compressed and exhausted by the thrust of the large cylinder 5. After the compression is completed, the small cylinder 6 is controlled through the solenoid valve to push the pressing block 14 to move downward, and the pressing block 14 presses the bag mouth of the packaging bag on the heating strip 18 and heats it to achieve the sealing effect of the packaging bag. After completion, first the small cylinder 6 retracts the pressing block 14, and then the large cylinder 5 retracts the cylinder rod to raise the lifting frame 8, and the vacuum packaging of the dental scarf paper is completed.

[0017] Example 2: Adjust the positioning blocks 9 on both sides according to the size of the dental scarf paper. Control the servo motor 7 to drive the lead screw 16 to rotate through the PLC control system 4. Drive the positioning block 9 to move through the rotation of the lead screw 16. The moving distance is set through the parameters of the PLC control system 4. After moving to the designated location, the servo motor 7 stops operating and the positioning block 9 remains stationary. After the positioning blocks 9 move to both sides, T-shaped grooves will be exposed on the working panel 15. Just place a cover plate with the same width and height on the step of the T-shaped groove 17 to avoid the dental scarf paper being uneven and wrinkled after extrusion due to the exposed T-shaped groove 17 during the extrusion process. After placing it, vacuum packaging can be started.

[0018] The beneficial effects produced by the present invention are as follows: The air in the packaging bag is exhausted by the method of squeezing from top to bottom by the flat plate 22, and the packaging bag is directly sealed by heat melting after extrusion. The flat plate levels the paper. This method will not cause the dental scarf paper in the packaging bag to wrinkle, and reduces the volume, which is convenient for packaging and transportation. It occupies less space when packing in a box and can ensure the sealing performance of the package; Guide columns 12 are provided at both ends of the lifting frame 8, and the guide columns 12 pass through the top of the support frame 2. The purpose is to avoid tilting when the lifting frame 8 presses down, ensure the vacuum packaging is complete and ensure flatness at the same time, so as to facilitate boxing and stacking; The positioning block 9 is set to be adjustable, so that the position of the positioning block 9 can be adjusted according to the size of the dental scarf paper. One of the functions of the positioning block 9 is to place the dental scarf paper in the middle position of the working panel 15 to avoid tilting during extrusion. The other is to prevent the packaging bag from bulging to the side during the extrusion process, resulting in incomplete exhaust; Control the servo motor 7 to drive the lead screw 16 to move through the parameter setting of the PLC control system 4, and the lead screw 16 drives the positioning block 9 to move. The moving distance is determined according to the parameter setting of the PLC control system 4.
