Detailed Implementation
[0022] 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.
[0023] like Figures 1 to 4As shown, an embodiment of the present invention provides a packaging bag exhaust device, including a conveyor frame 1; a pneumatic module 10 is installed in the middle of the conveyor frame 1; a fixed frame 11 is installed at the output end of the pneumatic module 10; two connecting frames 13 are installed on the side wall of the conveyor frame 1; the two connecting frames 13 are arranged opposite to each other; a fixed frame 11 is installed in the middle of the two connecting frames 13; a mounting plate 16 is installed in the middle of the fixed frame 11; an exhaust sponge block 12 is fixedly connected to the middle of the mounting plate 16; an installation component 2 is provided in the middle of the fixed frame 11 and the mounting plate 16; a pressing component 3 is installed in the middle of the conveyor frame 1; a connecting plate 14 is fixedly connected to the side wall of one of the fixed frames 11; a brush bristle 15 is fixedly connected to the middle of the connecting plate 14; and a brush bristle 15 is fixedly connected to the middle of the connecting plate 14. The unit is equipped with a dust collection component 4; the mounting component 2 includes multiple mounting slots 21; the multiple mounting slots 21 are located in the middle of the fixing frame 11; the top of the mounting plate 16 has multiple fixing slots 22; the multiple fixing slots 22 correspond to the mounting slots 21; two locking blocks 23 are fixedly connected to the side wall of the fixing slot 22; the two locking blocks 23 are arranged opposite to each other; a sliding rod 24 is fixedly connected to the middle of the mounting slot 21; two fixing plates 25 are slidably connected to the middle of the sliding rod 24; a mounting hole 26 is provided in the middle of the fixing plate 25; the mounting hole 26 corresponds to the position of the locking block 23; a first spring 27 is fixedly connected to the middle of the two fixing plates 25; the first spring 27 is located outside the sliding rod 24; a lever 28 is fixedly connected to the top of the fixing plate 25.During operation, when the packaging bag is sealed, it is conveyed by the conveying system. The pneumatic module 10 controls the fixed frame 11 to move up and down, raising or lowering it as needed. A sealing device is installed between the two fixed frames 11. After the packaging bag is longitudinally sealed, it is vented a second time. The packaging bag and the venting sponge block 12 move relative to each other, squeezing out the air inside the sealed bag. As the usage time increases, the venting sponge block 12 will gradually decompose and wear. The venting sponge block 12 can be quickly disassembled and assembled using the installation component 2. The pressing component 3 applies buffer pressure to the sealed bag for stable transmission. At the same time, when the brush 15 cleans the sealed bag, the dust suction component 4 collects the intercepted impurities. When replacement is needed, the two levers 28 are squeezed to move towards the center, and the two fixed plates 25 slide in the middle of the slide bar 24. The first spring 27 elastically contracts as the fixed plates 25 move, causing the two fixed plates 25 to move out of the clamp. When the middle of block 23 is close to the mounting plate 16, remove the mounting plate 16 from the middle of the fixing frame 11 to replace the exhaust sponge block 12. When installing the exhaust sponge block 12, place the mounting plate 16 inside the fixing frame 11, press the ends of the two fixing plates 25 into the fixing groove 22, release the two levers 28, and the elasticity of the first spring 27 causes the two fixing plates 25 to slide back to their original position in the middle of the slide rod 24, so that the locking block 23 enters the middle of the corresponding mounting hole 26, and the mounting plate 16 is fixed by the fixing plate 25. The above structure allows for quick replacement of the exhaust sponge block 12, timely replacement of worn sponge plates, effectively reducing exhaust obstruction caused by wear of the exhaust sponge block 12, effectively reducing the tedious disassembly and assembly steps of the exhaust sponge block 12, effectively reducing equipment downtime caused by tedious disassembly and assembly operations, improving maintenance efficiency, and allowing the replacement of exhaust sponge blocks 12 of different sizes to adapt to the exhaust requirements of various bag types.
[0024] like Figure 1 and Figure 4As shown, the pressing assembly 3 includes two supports 31; the two supports 31 are fixed to the two side walls of the conveyor frame 1; a connecting rod 32 is installed in the middle of the support 31; a roller 33 is rotatably connected to the end of the connecting rod 32; two sets of first sliding grooves 34 are opened at the end of the roller 33; the two sets of first sliding grooves 34 are arranged opposite to each other; each set of first sliding grooves 34 is equidistantly distributed; a sliding plate 35 is slidably connected in the middle of the first sliding groove 34; a second spring 36 is fixedly connected in the middle of the sliding plate 35; the end of the second spring 36 is fixedly connected to one end of the first sliding groove 34; buffer plates 37 are fixedly connected to the ends of the two opposite sliding plates 35; elastic cloth 38 is fixedly connected to the side walls of the two adjacent buffer plates 37; during operation, multiple packaging bags are conveyed. The buffer plate 37 contacts the packaging bag. As the packaging bag moves, the roller 33 rotates at the end of the connecting rod 32. Multiple buffer plates 37 move in the packaging bag along with the roller 33. When packaging bags of different thicknesses are vented, the slide plate 35 slides in the middle of the first slide groove 34 and causes the second spring 36 to elastically contract. As the elastic buffer cloth 38 of the buffer plate 37 elastically expands and contracts, the conveying position of the packaging bag is fixed. Through the above structure, the slide plate 35 is adaptively adjusted according to the thickness of the packaging bag, so that the slide plate 35 is in closer contact and fixed with the packaging bag, which can effectively buffer the packaging bag and effectively absorb the pressure between the roller 33 and the packaging bag, thereby reducing the damage to the packaging bag.
[0025] like Figure 1 and Figure 3 As shown, the vacuuming assembly 4 includes a vacuum cleaner 41; the vacuum cleaner 41 is installed in the middle of the connecting frame 13; a connecting pipe 42 is installed in the middle of the vacuum cleaner 41; a support plate 43 is fixedly connected to the bottom of the connecting plate 14; the support plate 43 is disposed between the brush bristles 15 and the exhaust sponge block 12; a suction pipe 44 is fixedly connected to the end of the support plate 43; a suction groove 45 is opened in the middle of the suction pipe 44; the end of the connecting pipe 42 is connected to one end of the suction pipe 44; during operation, when the surface of the packaging bag is cleaned by the brush bristles 15, impurities are concentrated on one side of the brush bristles 15. At the same time, the vacuum cleaner 41 is turned on, and the negative pressure airflow inside the vacuum cleaner 41 sucks in the impurities accumulated on one side of the brush bristles 15. The impurities enter the suction pipe 44 through the suction groove 45, and then enter the vacuum cleaner 41 through the connecting pipe 42 for collection. Through the above structure, the intercepted impurities can be quickly and concentratedly collected, reducing the accumulation of impurities, effectively reducing secondary pollution caused by the accumulation of impurities, and reducing the difficulty and intensity of subsequent cleaning work.
[0026] like Figure 4As shown, a second groove 5 is provided at the bottom of the connecting rod 32; a damping slider 51 is slidably connected in the middle of the second groove 5; a positioning plate 52 is fixedly connected to the end of the damping slider 51; during operation, the positioning plate 52 is moved according to the position of both sides of the packaging bag, so that the positioning plate 52 is in contact with one side of the packaging bag. During the movement of the packaging bag, the positioning plate 52 positions the packaging bag. The above structure can effectively reduce the deviation of the packaging bag during the exhaust process, maintain the stable conveying position of the packaging bag, and make the exhaust sponge block 12 act more accurately on the packaging bag, thereby improving the exhaust efficiency and effect.
[0027] like Figure 4 As shown, an elastic pad 6 is fixedly connected to the middle of the buffer plate 37; the elastic pad 6 is fixedly connected to the outer wall of the buffer plate 37; during operation, when the packaging bag is fixed, the flexible material of the elastic pad 6 contacts the surface of the packaging bag. The above structure can effectively reduce the direct friction between the sliding plate 35 and the packaging bag, and reduce the wear or damage of the packaging bag during the exhaust process.
[0028] like Figure 3 As shown, a guide plate 7 is fixedly connected to the middle of the suction pipe 44; the guide plate 7 is fixedly connected to the side near the suction groove 45; the guide plate 7 is arc-shaped; during operation, during the suction process, the airflow is guided by the guide plate 7 through the suction groove 45 into the inside of the suction pipe 44. The above structure enables the suction groove 45 to effectively capture the cleaned dust and debris, thereby improving the suction efficiency.
[0029] During operation, when the packaging bag is sealed, it is conveyed by the conveying system. The pneumatic module 10 controls the fixed frame 11 to move up and down, raising or lowering it as needed. A sealing device is installed between the two fixed frames 11. After the packaging bag is longitudinally sealed, it is vented a second time. The packaging bag and the venting sponge block 12 move relative to each other, squeezing out the air inside the sealed bag. As the usage time increases, the venting sponge block 12 will gradually decompose and wear. The venting sponge block 12 can be quickly disassembled and assembled using the installation component 2. The pressing component 3 applies buffer pressure to the sealed bag for stable transmission. At the same time, when the brush 15 presses the sealed bag... During cleaning, the dust collection assembly 4 collects the intercepted impurities. When replacement is needed, the two levers 28 are squeezed to move towards the center, and the two fixing plates 25 slide in the middle of the slide bar 24. The first spring 27 elastically contracts as the fixing plates 25 move, causing the two fixing plates 25 to move out of the middle of the locking block 23 and move closer together. At this time, the mounting plate 16 is removed from the middle of the fixing frame 11, thereby replacing the exhaust sponge block 12. When installing the exhaust sponge block 12, the mounting plate 16 is placed inside the fixing frame 11, and the ends of the two fixing plates 25 that are in contact are squeezed into the fixing groove 22. The two levers 28 are released, and the elasticity of the first spring 27 causes the two fixing plates to move out of the middle of the locking block 23 and move closer together. 25 slides back to its original position in the middle of the slide bar 24, allowing the locking block 23 to enter the middle of the corresponding mounting hole 26. The mounting plate 16 is fixed by the fixing plate 25. During the conveying of the packaging bag, multiple buffer plates 37 contact the packaging bag. As the packaging bag moves, the roller 33 rotates at the end of the connecting rod 32, and the multiple buffer plates 37 move in the packaging bag with the roller 33. When packaging bags of different thicknesses are vented, the slide plate 35 slides in the middle of the first slide groove 34 and causes the second spring 36 to elastically contract. As the elastic buffer cloth 38 of the buffer plate 37 elastically expands and contracts, the conveying position of the packaging bag is fixed. When the surface of the packaging bag is cleaned by the brush 15, impurities are removed. The impurities are concentrated on one side of the bristles 15. At the same time, the vacuum cleaner 41 is turned on. The negative pressure airflow inside the vacuum cleaner 41 sucks in the impurities accumulated on one side of the bristles 15. The impurities enter the vacuum tube 44 through the vacuum groove 45, and then enter the vacuum cleaner 41 for collection through the connecting tube 42. According to the position of the two sides of the packaging bag, the positioning plate 52 is moved so that the positioning plate 52 is attached to one side of the packaging bag. During the movement of the packaging bag, the positioning plate 52 positions the packaging bag. When the packaging bag is fixed, the flexible material of the elastic pad 6 contacts the surface of the packaging bag. During the vacuuming process, the airflow is guided by the guide plate 7 through the vacuum groove 45 into the vacuum tube 44.
