[0006] This utility model provides a bottom edge sealing device for an eight-side sealing machine to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A bottom edge sealing device for an eight-side sealing bag machine includes a base, a support frame fixedly connected to the outer periphery of the base, a conveying mechanism movably connected to the middle of the support frame, hot press plates slidably connected to the front and rear sides of the middle of the base, and a drive mechanism movably connected to the lower part of the inner cavity of the base.

[0009] The driving mechanism includes a fixed plate, which is fixedly connected to the lower part of the inner cavity of the base. A rotating wheel is rotatably connected to the right side of the fixed plate. Two connecting rods distributed front and rear are rotatably connected to the upper and lower sides of the rotating wheel, respectively. A sliding plate is fixedly connected to the lower surface of the hot press plate. The rear end of the upper connecting rod is rotatably connected to the front side of the rear sliding plate, and the front end of the lower connecting rod is rotatably connected to the rear side of the front sliding plate. A motor is fixedly connected to the right side of the inner cavity of the base. A transmission wheel is fixedly connected to the output end of the motor. A toothed belt meshes with the outer circumferences of the rotating wheel and the transmission wheel.

[0010] Preferably, a partition plate is fixedly connected to the middle of the base, and fixed pressure plates are fixedly connected to both the front and rear sides of the partition plate. Heating elements are fixedly connected to the middle of the opposite side of the fixed pressure plate and the hot pressure plate, and a cooling mechanism is movably connected to the left side of the base.

[0011] Preferably, the cooling mechanism includes a second cooling plate, which is fixedly connected to the upper part of the left side of the base. Two first cooling plates are slidably connected to the upper part of the left side of the base, and a connecting plate is fixedly connected to the right side of the first cooling plate. The right side of the connecting plate is fixedly connected to the left side of the hot press plate.

[0012] Preferably, the lower surface of the first cooling chip is fixedly connected to two sliders distributed on the left and right, and the left side of the base is fixedly connected to two sliding rods distributed on the left and right, with the sliders slidably connected to the outer periphery of the sliding rods.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-6 As shown, a bottom edge sealing device for an eight-side sealing bag machine includes a base 1, a support frame 2 fixedly connected to the outer periphery of the base 1, a conveying mechanism 3 movably connected to the middle of the support frame 2, hot press plates 5 slidably connected to the front and rear sides of the middle of the base 1, and a drive mechanism 7 movably connected to the lower part of the inner cavity of the base 1.

[0028] The drive mechanism 7 includes a fixed plate 74, which is fixedly connected to the lower part of the inner cavity of the base 1. A rotating wheel 75 is rotatably connected to the right side of the fixed plate 74. Two connecting rods 76 distributed front and rear are rotatably connected to the upper and lower sides of the rotating wheel 75, respectively. A sliding plate 77 is fixedly connected to the lower surface of the hot press plate 5. The rear end of the upper connecting rod 76 is rotatably connected to the front side of the rear sliding plate 77, and the front end of the lower connecting rod 76 is rotatably connected to the rear side of the front sliding plate 77. A motor 71 is fixedly connected to the right side of the inner cavity of the base 1. A transmission wheel 72 is fixedly connected to the output end of the motor 71. A toothed belt 73 meshes with the outer periphery of the rotating wheel 75 and the transmission wheel 72.

[0029] It should be noted that the base 1, as the basic support structure of the entire bottom edge sealing device, provides a platform for the installation and fixation of other components, ensuring that each component maintains a stable position during operation and enabling the device to operate normally. The support frame 2 mainly supports and positions the conveying mechanism 3. It ensures the stability and levelness of the conveying mechanism 3 during operation, preventing tilting or swaying due to its own weight or uneven force, ensuring that the octagonal bags enter the sealing station accurately and smoothly during transport. The conveying mechanism 3 is responsible for accurately transporting the octagonal bags to be sealed to the sealing station and maintaining stable transport of the bags during the sealing process, ensuring continuous and uniform sealing operations. The hot press plate 5, in conjunction with the fixed press plate 10, performs hot press sealing on the bottom edge of the octagonal bags.

[0030] Motor 71 serves as the power source for drive mechanism 7, providing rotational power for the entire drive mechanism 7. Motor 71 drives transmission wheel 72 to rotate via its output end, thereby driving the rotating wheel 75 to rotate. Transmission wheel 72 meshes with toothed belt 73, transmitting power from transmission wheel 72 to rotating wheel 75 through toothed belt 73, realizing power transmission and conversion, enabling rotating wheel 75 to rotate at a predetermined speed and direction. Fixed plate 74 provides a mounting and fixing position for rotating wheel 75, ensuring the stability of rotating wheel 75 during rotation, preventing shaking or displacement during operation, and ensuring the normal operation of drive mechanism 7. When rotating wheel 75 rotates, connecting rod 76 converts the rotational motion of rotating wheel 75 into the forward and backward linear motion of sliding plate 77, which in turn drives hot press plate 5 to slide back and forth, automating the edge sealing operation.

[0031] like Figure 2 As shown, a partition plate 6 is fixedly connected to the middle of the base 1, and a fixed pressure plate 10 is fixedly connected to both the front and rear sides of the partition plate 6. A heating element 9 is fixedly connected to the middle of the opposite side of the fixed pressure plate 10 and the hot pressure plate 5. A cooling mechanism 4 is movably connected to the left side of the base 1.

[0032] It should be noted that the separator 6 separates the bottom edge of the octagonal bag, ensuring that the two bottom edges of the bag are positioned between the two sets of fixed pressure plates 10 and the hot pressure plate 5, thus ensuring the accuracy and quality of the sealing operation. The fixed pressure plates 10 and the hot pressure plates 5 work together to complete the hot-press sealing operation of the bottom edge of the octagonal bag. The fixed pressure plates 10 remain stationary during the sealing process, providing stable support and a pressing surface for the bottom edge of the octagonal bag. Working together with the hot pressure plates 5, they allow the plastic material to fully melt and fuse, forming a strong seal. The heating element 9 is used to heat the hot pressure plates 5 and the fixed pressure plates 10. The heating element 9 converts electrical energy into heat energy, allowing the hot pressure plates 5 and the fixed pressure plates 10 to reach a suitable sealing temperature, ensuring that the plastic material can fully melt and achieve a good sealing effect.

[0033] like Figure 5 As shown, the cooling mechanism 4 includes a second cooling plate 42, which is fixedly connected to the upper left side of the base 1. Two first cooling plates 41 are slidably connected to the upper left side of the base 1. A connecting plate 45 is fixedly connected to the right side of the first cooling plate 41, and the right side of the connecting plate 45 is fixedly connected to the left side of the hot press plate 5.

[0034] It should be noted that after the hot press plate 5 completes the edge sealing operation, the cooling plate 41 moves together with the hot press plate 5 to cool the bottom edge of the sealed eight-sided bag, accelerating the curing of the plastic material at the sealed area, preventing deformation or adhesion of the sealed area due to high temperature, and improving the quality and stability of the edge sealing. The cooling plate 42 works in conjunction with the cooling plate 41 to cool the bottom edge of the sealed eight-sided bag, improving cooling efficiency and ensuring that the sealed area can be cooled quickly and evenly, further ensuring the quality of the edge sealing. The connecting plate 45 enables the cooling plate 41 to move synchronously with the hot press plate 5, ensuring that the cooling plate 41 can cool the sealed area in time after the hot press plate 5 completes the edge sealing operation, and allowing the heat sealing and cooling of two adjacent eight-sided bags to occur simultaneously.

[0035] like Figure 5 As shown, two sliders 43 are fixedly connected to the lower surface of the cooling chip 41, and two sliding rods 44 are fixedly connected to the left side of the base 1. The sliders 43 are slidably connected to the outer periphery of the sliding rods 44.

[0036] It should be noted that the cooperation between slider 43 and slide bar 44 provides guidance and support for the movement of cooling plate 41, ensuring the stability and straightness of cooling plate 41 during its movement with hot press plate 5, so that the cooling operation can be carried out accurately and effectively.

[0037] like Figure 3 As shown, two guide grooves 11 are provided on the left and right sides of the base 1, and the left and right ends of the guide grooves 11 are both isosceles trapezoids.

[0038] It should be noted that the guide groove 11 plays a guiding and positioning role when the octagonal bag enters the sealing device. The isosceles trapezoidal structure can guide the octagonal bag to enter the predetermined position more smoothly, reduce sealing deviation caused by inaccurate positioning, and improve the accuracy and quality of sealing.

[0039] like Figure 6 As shown, a cleaning mechanism 8 is movably connected to the right side of the base 1. The cleaning mechanism 8 includes a collection box 81, which is slidably connected to the right side of the base 1. Two sets of front-to-back distributed brush plates 82 are fixedly connected to the upper surface of the collection box 81. Brush bristles 83 are fixedly connected to the opposite side of the two front-to-back distributed brush plates 82.

[0040] It should be noted that the collection box 81 is used to collect debris, dust, and other impurities generated when the octagonal bags pass through the cleaning mechanism 8, and also facilitates regular cleaning and maintenance. During the conveying process of the octagonal bags, the brush bristles 83 can remove dust, impurities, etc. from the bottom surface of the octagonal bags, ensuring the cleanliness of the sealing area and improving the quality and reliability of the sealing. At the same time, the brushed impurities will fall into the collection box 81 for centralized disposal.

[0041] like Figure 6As shown, the collection box 81 has two collection slots 84 distributed in front and behind, and the left and right sides of the collection slots 84 are inclined downwards.

[0042] It should be noted that the left and right sides of the collection trough 84 are inclined downwards, which helps impurities slide more smoothly into the collection box 81, avoids impurities accumulating on the surface of the collection box 81, improves collection efficiency, and also makes it easier to clean impurities inside the collection box 81.

[0043] The working principle of this utility model is as follows: An octagonal bag with an unsealed bottom edge is fixed on the conveyor belt of the conveying mechanism 3. The bottom edge of the octagonal bag enters the base 1 along the guide groove 11. The conveying mechanism 3 is started, which drives the octagonal bag through the cleaning mechanism 8. The brush 83 cleans the dust and other impurities on the bottom plate of the octagonal bag, and the impurities fall into the collection groove 84 and are collected. Then, the bottom plate of the octagonal bag is separated by the partition plate 6, so that the two bottom edges are respectively placed between two sets of fixed pressure plates 10 and hot pressure plates 5 distributed vertically. The heating element 9 is started to preheat the fixed pressure plates 10 and hot pressure plates 5. At the same time, the motor 71 is started to drive the transmission wheel 72 to rotate. The toothed belt 73 transmits the power of the transmission wheel 72 to the rotating wheel 75. The rotation of the rotating wheel 75 causes the connecting rod 76 to reciprocate the sliding plate 77. The reciprocating motion of the sliding plate 77 causes the hot pressure plate 5 to reciprocate as well, thereby heat-sealing the bottom edge of the octagonal bag. After heat sealing is completed, the conveying mechanism 3 continues to operate to transport the uncooled octagonal bag to the cooling mechanism 4. At the same time, the next unheated octagonal bag is transported to the heat sealing area for heat sealing. While the hot press plate 5 heat seals the octagonal bag, the connecting plate 45 drives the cooling plate 41 to cool the heat-sealed octagonal bag.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
