Specific embodiments

[0022] The technical solution of the present utility model will be further described below in conjunction with specific embodiments:

[0023] As Figure 1 shown, a serrated knife cutting edge constant temperature heating type packaging and sealing device includes a sealing bracket, an upper sealing part 2, a lower sealing part 3 and upper and lower air suction components 4. The upper sealing part and the lower sealing part 3 are respectively installed on the upper and lower parts of the sealing bracket assembly 1, and the upper and lower air suction components 4 are connected to the lower sealing part 3. When the device is in use, the packaging bag is placed between the upper sealing part 2 and the lower sealing part 3, and the upper sealing part 2 moves downward until it fits with the lower air outlet part and then the bag cutting process is carried out.

[0024] As Figure 2 shown, the sealing bracket includes an upper support plate 11, two sealing guide shafts 12 and a lower support plate 13. The two ends of the lower surface of the upper support plate 11 are respectively fixedly connected to the two ends of the upper surface of the lower support plate 13 through the two sealing guide shafts 12. The sealing bracket mainly plays a role of support and fixation.

[0025] As Figure 3 shown, the upper sealing part 2 includes a cutting cylinder 21, a guide mechanism 22, a serrated cutter 25, a bag pressing plate 26, a cutter fixing block 27, two cylinder fixing blocks 23 and two first guide bearings 3224. One cylinder fixing block 23 is fixedly installed on each side of the cylinder body of the cutting cylinder 21. The air rod of the cutting cylinder 21 is in transmission connection with the serrated cutter 25 through the cutter fixing block 27. The bag pressing plate 26 is arranged on the front side of the serrated cutter 25 and is fixedly connected to the cutter fixing block 27. The guide mechanism 22 includes two guide components. The two guide components are respectively located on both sides of the cutting cylinder 21. The two cylinder fixing blocks 23 are respectively located on the side of the guide component far from the cutting cylinder 21. The two cylinder fixing blocks 23 are respectively fixedly connected to a first guide bearing 3224. The two first guide bearings 3224 are respectively sleeved and fixed on a sealing guide shaft 12. When the device works, the air rod of the cutting cylinder 21 drives the cutter fixing block 27 to move, driving the serrated cutter 25 to cut the bag mouth of the packaging bag. The cutter uses a serrated cutter 25, which can make the cut seal present a serrated shape, more beautiful and also more convenient for opening the packaging bag.

[0026] The guiding component includes a fixed ring, a sliding rod, and a limiting ring. The fixed ring is fixedly connected to the cylinder fixing block 23, the fixed ring is sleeved on the sliding rod, the limiting ring is arranged at the top end of the sliding rod, and the bottom end of the sliding rod is fixedly connected to the cutter fixing block 27.

[0027] As Figure 4 shown in the figure, the lower sealing part 3 includes a lower support plate 31, two second guiding bearings 3224, a heat insulation plate 33, an asbestos board 34, a heating copper block 35, and a silica gel strip 36. The two ends of the lower support plate 31 are respectively connected to the sealing guiding shaft 12 through a second guiding bearing 3224. A heating rod and a thermocouple are installed in the heating copper block 35. The asbestos board 34 is installed on the front side of the lower support plate 31, the heating copper block 35 is fixed on the asbestos board 34, and the heat insulation plate 33 and the silica gel strip 36 are respectively installed on the front and back sides of the heating copper block 35.

[0028] When the equipment is in use, the bag pressing plate 26 and the serrated cutter 25 of the upper sealing part 2 move downward until the bag pressing plate 26 is in close contact with the silica gel strip 36 of the lower air outlet part to clamp the packaging bag. Grooves are formed on the bag pressing plate 26. Both the grooves and the silica gel strip 36 are used to increase the friction force to prevent the bag from shifting during cutting, providing an effective guarantee for the subsequent cutting work.

[0029] After the fitting is completed, the cylinder drives the serrated blade to cut out a serrated effect at the bag mouth. At the same time, the sealing part uses a constant temperature heating method to seal the packaging bag. That is, the heating rod installed inside the heating copper block 35 is used to heat the heating copper block 35, and the thermocouple installed in the heating copper block 35 is used to detect the temperature. When the appropriate sealing process temperature is reached, heat preservation is carried out.

[0030] As Figure 5 shown in the figure, the upper and lower air suction components 4 include a waste collection port 41 and a waste suction port 42. After the sealing is completed, the serrated knife also completes the cutting action. At this time, the cut scraps fall into the waste collection port 41, and a negative pressure device is arranged in the waste suction port 42 to form a negative pressure to suck the scraps.

[0031] This embodiment is only a further explanation of the present invention, not a limitation of the present invention. Those skilled in the art can make non-creative modifications to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
