Description

Technical Field

[0001] This utility model relates to the field of food packaging bag technology, specifically to a hot-stamping device for food packaging bags. Background Technology

[0002] With the continuous development of technology, food packaging bag manufacturing equipment has achieved automated production line production. When the food packaging bags are hot-stamped, the packaging bags are transported by a conveyor belt and stop under the hot-stamping blade of the hot-stamping device. After the hot-stamping device hot-stamps the packaging bags, the conveyor belt continues to work, and the above operation is repeated to complete the hot-stamping of all food packaging bags.

[0003] In actual production, due to the large number of food packaging bags, each food packaging bag needs to be hot-pressed. Repeatedly pressing the hot-pressing knife will cause significant wear and tear on the equipment. Long-term operation may damage the hot-pressing device and require replacement of the hot-pressing knife. Furthermore, the existing heating plate is not easy to disassemble and cannot be replaced with heating plates of different sizes according to different products. Therefore, a hot-pressing device for food packaging bags is proposed. Utility Model Content

[0024] Please see Figures 1-5A hot-stamping device for food packaging bags includes a stabilizing plate 1. Four transmission plates 2 are fixedly connected to the top of the stabilizing plate 1. A packaging bag conveyor belt 3 is installed between two transmission plates 2. A stabilizing block 4 is fixedly connected to the top of the stabilizing plate 1. A connecting plate 5 is fixedly connected to the top of the stabilizing block 4. A support plate 6 is fixedly connected between two connecting plates 5. An electric telescopic rod 7 is fixedly connected to the top of the support plate 6. The bottom end of the electric telescopic rod 7 extends to the bottom end of the support plate 6 and is fixedly connected to a fixing block 8. A heating plate 9 is installed at the bottom end of the fixing block 8 via a disassembly and assembly mechanism. The disassembly and assembly mechanism includes two mounting blocks 1. 0. One end of each of the two mounting blocks 10 is fixedly connected to the bottom sides of the support plate 6. Each mounting block 10 has a sliding groove at its closest point. One end of each sliding groove has a fixing groove, and one end of each fixing groove has a pushing through hole. A pushing rod 11 is slidably connected inside each pushing through hole. One end of each pushing rod 11 is fixedly connected to a pushing block 12. Both ends of the heating plate 9 are fixedly connected to sliding blocks 13. Each sliding block 13 is slidably connected to the interior of one of the two sliding grooves. One end of each sliding block 13 has a limiting groove. The two ends of the limiting groove... Each of the two limiting sliders 14 is slidably connected, and a limiting plate 15 is fixedly connected between the two limiting sliders 14. A trapezoidal block 16 is fixedly connected to one end of the limiting plate 15, and a return spring 17 is installed between one end of the limiting plate 15 and one end inside the limiting groove. After the food packaging bag is placed on the packaging bag conveyor belt 3 and its area to be heated is moved to the bottom of the heating plate 9, the heating plate 9 will contact the area of ​​the packaging bag to be heated under the operation of the electric telescopic rod 7, and the heating plate 9 will complete the heating of the packaging bag. Subsequently, the pushing rod 11 will push the heating plate 9 to complete the heating of the packaging bag. Next, by pushing block 12 to contact trapezoidal block 16, and using the inclined surface of trapezoidal block 16 to make it re-extend into the interior of the limiting groove, the sliding block 13 can be easily moved inside the sliding groove, thereby completing the disassembly of the heating plate 9. Subsequently, the sliding block 13 in another heating plate 9 moves inside the sliding groove until its trapezoidal block 16 re-extends into the interior of the fixing groove, thereby completing the fixation of the position of the heating plate 9. Compared with the screw fixation in the prior art, this further improves the convenience of disassembling the heating plate 9, and realizes the effect of replacing heating plates 9 of different sizes according to different products.

[0025] Please see Figure 3A pressure buffer mechanism is installed between the bottom two sides of the support plate 6 and the two ends of the stabilizing block 4. The pressure buffer mechanism includes two buffer blocks 18, which are fixedly connected to the two ends of the stabilizing block 4. Buffer rods 19 are fixedly connected between the bottom two sides of the support plate 6 and the top two sides of the buffer blocks 18. Buffer sleeves 20 are slidably connected between the two buffer rods 19. Limiting grooves are opened at one end of each of the two connecting plates 5. Buffer sliders 21 are slidably connected inside the two limiting grooves. One end of the buffer slider 21 is fixedly connected to one end of the buffer sleeve 20, and the other end of the buffer slider 21 is fixedly connected to both ends of the fixed block 8. Buffer springs 22 are sleeved on the outer walls of the four buffer rods 19. After the heating plate 9 contacts the packaging bag, when the telescopic rod moves the fixed block 8, the buffer sleeves 20 are moved on the outer walls of the buffer rods 19 by the buffer sliders 21 to buffer the movement of the fixed block 8.

[0026] It should also be noted that the top of the stabilizing block 4 has a pressing groove, and multiple pressing sliders 23 are slidably connected to both ends of the pressing groove. A pressing block 24 is fixedly connected between the multiple pressing sliders 23. Multiple pressing springs 25 are fixedly installed between the bottom end of the pressing block 24 and the bottom end of the pressing groove. The packaging bag will move the pressing block 24 by the downward pressure, and the movement of the pressing block 24 will be buffered by the stabilizing springs 29. A trapezoidal slider 26 is fixedly connected to the top of the heating plate 9, and the bottom end of the fixing block 8 has... A trapezoidal groove is provided, and the outer wall of the trapezoidal slider 26 is slidably connected to the inside of the trapezoidal groove to ensure stability when the heating plate 9 is slidably limited. Two push sliders 27 are fixedly connected to the outer wall of the push rod 11. One end of the two push sliders 27 is slidably connected to the two ends inside the push through hole, respectively. One end of each of the two push rods 11 is fixedly connected to a push plate 28. A stabilizing spring 29 is sleeved on the outer wall of the push rod 11 to limit the movement of the push rod 11 and to reset the push rod 11 by the tension of the stabilizing spring 29.

[0027] In summary, when using this hot-stamping device for food packaging bags, the food packaging bag is first placed on the packaging bag conveyor belt 3. After the area to be hot-stamped is moved to the bottom of the heating plate 9, the electric telescopic rod 7 drives the heating plate 9 to contact the area to be hot-stamped on the packaging bag, and the heating plate 9 completes the hot-stamping process. Subsequently, under the push of the push rod 11, the push block 12 contacts the trapezoidal block 16, and the inclined surface of the trapezoidal block 16 causes it to re-enter the interior of the limiting groove, allowing the sliding block 13 to move easily within the sliding groove, thereby completing the disassembly of the heating plate 9. Subsequently, the sliding block 13 in another heating plate 9... 3. The heating plate 9 is fixed in position after moving inside the sliding groove until the trapezoidal block 16 re-enters the fixed groove. Compared with the screw fixation in the prior art, the ease of disassembling the heating plate 9 is further improved, and the heating plate 9 of different sizes can be replaced according to different products. After the heating plate 9 contacts the packaging bag, the packaging bag will drive the lower pressure block 24 to move through the downward pressure, and the movement of the lower pressure block 24 will be buffered by the stabilizing spring 29. When the telescopic rod drives the fixed block 8 to move, the buffer sleeve 20 will move on the outer wall of the buffer rod 19 through the buffer slider 21 to buffer the downward movement of the fixed block 8.
