Description

Technical Field

[0001] The utility model relates to the technical field of deoxidizer package edges, in particular to a hot sealing edge device for deoxidizer packaging materials. Background Technique

[0002] A deoxidizer, also known as an oxygen remover or oxygen absorber, is an additive that can absorb oxygen and slow down the oxidation of food. During the production process, the deoxidizer needs to be packaged in a packaging material and then sealed by heat sealing. During the sealing process, fumes may be generated, and in order to timely process the fumes.

[0003] After retrieval

[0004] A hot sealing edge device for deoxidizer packaging materials, with the publication number: CN217970203U. Place the packaging material containing the deoxidizer directly below the hot sealing edge assembly, rotate the threaded cylinder to drive the movement of two lead screws, and the two lead screws drive the movement of two third heating plates. When the two third heating plates are adjusted to the appropriate positions, control the electric push rod to extend and drive the protective cover to move downward through the spring. The downward moving protective cover contacts the lower surface of the inner wall of the fixed frame, thereby isolating the packaging material containing the deoxidizer from the outside. Continue to control the electric push rod to extend, and the electric push rod moves downward within the protective cover, and the spring extends. When the electric push rod drives the hot sealing edge assembly to contact the packaging material through the connecting plate, the working hot sealing edge assembly can melt the packaging material and then seal the edge of the packaging material. The peculiar smell generated during edge sealing is discharged through the purification net, the fixed shell, and two conduits under the action of the exhaust fan.

[0005] However, when the packaging material is placed directly below the hot sealing edge assembly on the fixed frame, during the downward movement of the protective cover, in order to prevent interference, personnel need to evacuate the packaging material, so it is easy to cause the packaging material to shake and fall, which in turn leads to the misalignment of the bag mouth of the packaging material and the hot sealing edge assembly, resulting in the inability to seal the edge smoothly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] As shown Figures 1-5 in the figure, a heat-sealing edge device for a deoxidizer packaging material includes a mounting frame 2 equipped with a heat-sealing edge assembly. As shown Figure 1 in the figure, the heat-sealing edge assembly is longitudinally lifted and lowered on the mounting frame 2 by means of a threaded rod drive, and the structure of the heat-sealing edge assembly refers to the structure of the heat-sealing edge assembly in a heat-sealing edge device for a deoxidizer packaging material with the publication number CN217970203U to achieve the edge sealing of the packaging material bag mouth:

[0026] On the base of the mounting frame 2, two guide frames 4 are symmetrically and fixedly connected below the heat-sealing edge assembly. A backing plate 3 is penetrated through the two guide frames 4. During use, the packaging material is placed on the backing plate 3 to achieve the lifting of the bag bottom, and during actual use, the installation height of the backing plate 3 can be adjusted according to the height of the packaging material;

[0027] The upper surface of one of the guide frames 4 is recessed in a U shape, and a U-shaped seat 12 is rotatably connected to one of the inner side walls. Two connecting shafts 16 are symmetrically and rotatably connected to the inner bottom surface of the U-shaped seat 12. Transmission gears 11 are fixedly connected to the end faces of the two connecting shafts 16. The two transmission gears 11 are meshed, and a bag-supporting rod 6 for tightening the bag mouth is fixedly connected to the tooth surface of the transmission gear 11. When the packaging material is placed on the backing plate 3, the two bag-supporting rods 6 are inserted into the bag mouth, and when one of the transmission gears 11 rotates to drive the other transmission gear 11 to rotate in the opposite direction, the distance between the two bag-supporting rods 6 is increased, thereby straightening and tightening the bag mouth of the packaging material:

[0028] In addition, in order to drive one of the transmission gears 11 to rotate, a plug rod 14 penetrating through the U-shaped seat 12 is fixedly connected to the other side wall of the concave part at the top edge of the guide frame 4. A collar 1 is sleeved on the part of the plug rod 14 located inside the U-shaped seat 12. A double-shaft motor 15 is fixedly connected to the outer wall of the collar 1. A plurality of convex columns 17 are fixedly connected to one main shaft of the double-shaft motor 15. Bevel gears 13 are installed on both the inside of the U-shaped seat 12 and the connecting shaft 16 close to the plug rod 14. The two bevel gears 13 are meshed, and a rubber pad 18 that frictionally engages with the plurality of convex columns 17 is fixedly connected to the end face of the bevel gear 13 on the U-shaped seat 12. The two bevel gears 13 are respectively fixedly connected to the connecting shaft 16 and rotatably connected to the U-shaped seat 12. As shown Figure 4 and Figure 5 in the figure, the position of the collar 1 at this time is such that the plurality of convex columns 17 on one main shaft of the double-shaft motor 15 tightly abut against the rubber pad 18 on the end face of the bevel gear 13 on the U-shaped seat 12. Under the action of friction, when the plurality of convex columns 17 at one end driven by the double-shaft motor 15 rotate, under the action of friction, the bevel gear 13 rotatably connected to the U-shaped seat 12 drives the bevel gear 13 fixed on the connecting shaft 16 to rotate, thereby realizing the connecting shaft 16 driving the corresponding transmission gear 11 to rotate.

[0029] In order to lift packaging bags of different heights: One of the guide frames 4 passes through one side of the backing plate 3 and is arranged in a screw shape, and a nut threadedly connected to the screw-shaped part of the guide frame 4 is rotatably connected to the upper surface of the backing plate 3. By rotating the nut, the nut can be lifted and lowered on the guide frame 4, and then the backing plate 3 can be lifted and lowered on the guide frame 4 to achieve height adjustment. A slide plate 7 for supporting the bottom of the bag is slidably connected to the upper surface of the backing plate 3, and a blocking frame 8 is inserted into one side of the backing plate 3 close to the guide frame 4 through a spring rod. The two blocking frames 8 arranged can closely adhere to the body part of the packaging bag placed on the backing plate 3 under the pulling force of the spring rod to prevent the packaging bag from tipping over. In addition, by placing the packaging bag on the slide plate 7, when the two bag-supporting rods 6 straighten the bag opening, the bag opening of the packaging bag will move. Therefore, by using the sliding of the slide plate 7, the body of the packaging bag can move along with the movement of the bag opening.

[0030] In order to drive the U-shaped seat 12 to rotate so that the bag-supporting rod 6 disengages from the bag opening and prevent interference with the heat-sealing edge assembly: Another main shaft of the double-shaft motor 15 is fixedly connected with a spur gear 9. One end of the outer wall of the collar 1 is rotatably connected with a toothed ring 10 meshing with the spur gear 9. One end of the toothed ring 10 is also fixedly connected with a rubber pad 18. A number of convex columns 17 are fixedly connected to the inner wall of the U-shaped seat 12 at the same height as the collar 1. The number of convex columns 17 in the U-shaped seat 12 are used to frictionally engage with the rubber pad 18 on the collar 1. A telescopic electric rod 5 is fixedly connected between the outer wall of the collar 1 and the insertion rod 14. By using the telescopic electric rod 5 to extend, the collar 1 moves, so that the collar 1 moves along the surface of the insertion rod 14 until the rubber pad 18 on the collar 1 contacts and engages with a number of convex columns 17 on the side wall of the U-shaped seat 12. At this time, when the double-shaft motor 15 rotates again, a number of convex columns 17 at one end rotate idly, while the spur gear 9 at the other end drives the toothed ring 10 on the collar 1 to rotate, and then the rubber pad 18 on the end face rotates, and the convex columns 17 can be rotated under the action of friction, and the U-shaped seat 12 can be rotated, so that the bag-supporting rod 6 installed on the U-shaped seat 12 swings to disengage from between the two guide frames 4.

[0031] Further solution: The top edge of the other guide frame 4 is also installed with a telescopic electric rod 5, and the telescopic end of the telescopic electric rod 5 on the other guide frame 4 is also installed with a bag-supporting rod 6, and the cylinder part is rotatably connected to the guide frame 4. As shown in the figure, the telescopic electric rod 5 on the other guide frame 4 rotates and swings by installing an existing servo motor. Therefore, in this solution, the empty packaging bag can also be directly placed on the slide plate 7, and the two bag-supporting rods 6 on one of the guide frames 4 are used to tighten the bag opening. At the same time, the bag-supporting rod 6 on the other guide frame 4 is inserted into the bag opening and moves along with the contraction of the corresponding telescopic electric rod 5, and the bag opening can be opened.

[0032] Working principle: Place the packaged packaging material on the slide plate 7 on the backing plate 3. Adjust the installation height of the backing plate 3 according to the height of the packaging material. Then, the collar 1 slides on the insertion rod 14 until the rubber pad 18 on the collar 1 contacts and engages with several convex columns 17 on the side wall of the U-shaped seat 12. When the double-shaft motor 15 rotates, several convex columns 17 at one end rotate idly, while the spur gear 9 at the other end drives the toothed ring 10 on the collar 1 to rotate. Thus, the rubber pad 18 on the end face rotates, and the convex column 17 can be rotated under the action of friction, and the U-shaped seat 12 can be rotated, so that the bag-supporting rod 6 installed on the U-shaped seat 12 swings into the bag opening of the packaging material between the two guide frames 4. Then, the collar 1 slides again until several convex columns 17 on one of the main shafts of the double-shaft motor 15 tightly abut against the rubber pad 18 on the end face of the bevel gear 13 on the U-shaped seat 12. Under the action of friction, when the double-shaft motor 15 drives several convex columns 17 at one end to rotate, the bevel gear 13 rotatably connected to the U-shaped seat 12 drives the bevel gear 13 fixed on the connecting shaft 16 to rotate under the action of friction, and then the connecting shaft 16 drives the corresponding transmission gear 11 to rotate. When one transmission gear 11 rotates and drives the other transmission gear 11 to rotate in the opposite direction, the distance between the two bag-supporting rods 6 increases, so as to straighten and tighten the bag opening of the packaging material and ensure that the packaging material does not shake or tilt.

[0033] The wiring diagram of the electric telescopic rod 5 and the double-shaft motor 15 in the present utility model belongs to the common knowledge in the art. Its working principle is already known technology, and its model is selected according to actual use. Therefore, the control method and wiring layout of the electric telescopic rod 5 and the double-shaft motor 15 will not be explained in detail.

[0034] The above is only a preferred embodiment of the present utility model, and it is not a limitation to the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
