Description

Technical Field

[0001] The present invention relates to the technical field of container bag packaging, and in particular to a multi-stage packaging device used in container bag production and an operating method thereof. Background Art

[0002] A bulk bag is a flexible transport packaging container that is moisture-proof, dust-proof, radiation-resistant, firm and safe, and has sufficient structural strength. It is easy to load and unload and carry, and the loading and unloading efficiency is significantly improved. It has developed rapidly in recent years. It is generally made of polyester fibers such as polypropylene and polyethylene. After the bulk bag is processed, it needs to be packed for easy transportation. Since the bulk bag has a certain stretchability, a compressor is needed to compress it for easy packing.

[0003] For example, a packaging device for the production and processing of bulk bags with announcement number CN220764818U, through the arrangement of a clamping mechanism, a discharging mechanism and a clamping seat, can be packaged by passing the strapping belt through the pressure plate, the U-shaped block and the second slot after compression, thereby avoiding the stretching performance of the bulk bag itself, causing the bulk bag to bounce upward, thereby reducing the volume of the bulk bag and improving work efficiency. After packaging is completed, the electric push rod works to cause the push plate to rotate along the push plate rotation axis, thereby pushing out the packed bulk bag on the clamping seat for discharging operation without manual handling, thereby further improving packaging efficiency. However, in actual use, the bulk bag is made of polyester fibers such as polypropylene and polyethylene. Although it has high strength, the surface of the bulk bag is relatively smooth. When multiple bulk bags are compressed, the bulk bags are prone to sliding after being subjected to pressure, thereby causing multiple bulk bags to be skewed to a certain extent. During subsequent compression, the bulk bag is prone to slipping, thereby affecting the packaging quality of the bulk bag, and there are certain usage defects.

[0004] Therefore, we propose a multi-stage packaging equipment and an operation method thereof for use in container bag production in order to solve the above-mentioned problems. Summary of the invention

[0005] The object of the present invention is to provide a multi-stage packaging equipment and an operating method thereof for use in the production of bulk bags, so as to solve the problem that the bulk bags proposed in the above-mentioned background technology are made of polyester fibers such as polypropylene and polyethylene. Although they have high strength, the surface of the bulk bags is relatively smooth. When a plurality of bulk bags are compressed, the bulk bags are prone to sliding after being subjected to pressure, thereby causing the plurality of bulk bags to be skewed to a certain extent. When subsequently compressed, the bulk bags are prone to sliding, thereby affecting the packaging quality of the bulk bags.

The movable rods are divided into two groups. A movable frame is fixedly installed on one end of each group of two movable rods, and the U-shaped rod is slidably connected to the movable frame. The upper end of the movable frame is inclined, and the lower end of the movable frame is vertically set. A through groove is opened on the top of the upper pressure plate on one side of the movable frame.

[0007] Preferably, positioning frames are symmetrically installed on one side of the two groups of movable rods below the two sides of the fixed frame, and the insides of the two positioning frames are rotatably connected to rotating rods, and the outsides of the rotating rods are rotatably connected to connecting frames below, and the connecting frames are fixedly connected to the base.

[0008] By adopting the above technical solution, the rotation of the rotating rod can be stably supported and limited.

[0009] Preferably, a toothed plate is fixedly mounted on one end of each group of lower movable rods away from the movable frame, and a rotating gear is fixedly mounted on the outer upper part of the rotating rod, and the rotating gear is meshingly connected with the toothed plate.

[0010] By adopting the above technical solution, the movement of the movable frame can drive the rotating rod to rotate.

[0011] Preferably, a turntable is fixedly installed on the outside of the two sets of rotating rods above the connecting frame, and two sets of mounting frames are symmetrically installed on both sides of the rear of the base, and a sliding rod is slidably connected to the upper part of the mounting frame, and a limiting plate is fixedly installed on one end of the sliding rod.

[0012] By adopting the above technical solution, the front and rear sides of multiple container bags can be limited.

[0013] Preferably, a return spring is sleeved on one side of the exterior of the two sets of sliding rods, one end of the return spring is fixedly connected to the mounting frame, and the other end of the return spring is fixedly connected to the limit plate.

[0014] By adopting the above technical solution, the limiting plate can be easily reset after being moved.

[0015] Preferably, rubber ropes are fixedly installed on one side of the exterior of the two sets of turntables, and the ends of the two sets of rubber ropes away from the turntables are fixedly connected to the two sets of sliding rods respectively.

[0016] By adopting the above technical solution, the rotation of the rotating rod can drive the limiting plate to move.

[0017] Preferably, a threaded rod is fixedly installed at the bottom of the lower pressure plate (the rotation direction of the threaded rod in the accompanying drawing is only a schematic diagram), and a through hole is opened through the top center of the base, and positioning rods are symmetrically installed on both sides of the bottom of the lower pressure plate, and the positioning rods are slidably connected to the base, and the bottom end of the front right rotating rod passes through the connecting frame and is fixedly installed with a driving pulley, and a threaded sleeve is provided on the outer lower part of the threaded rod, and a driven pulley is fixedly installed on the outer lower part of the threaded sleeve, and the driven pulley is rotationally connected to the driving pulley through a belt.

[0018] By adopting the above technical solution, the lower pressure plate can be moved downward when the container bag is pressed, and it is convenient to reset the lower pressure plate after pressing.

[0019] Preferably, a fixing ring is fixedly installed on the upper part of the outside of the threaded sleeve, and a limiting frame is fixedly installed on the bottom of the base above the threaded sleeve, and a limiting ring is fixedly installed on the inner side of the limiting frame. At the same time, a limiting ring groove is opened on the inner side of the limiting ring, and the fixing ring is slidably connected to the limiting ring groove.

[0020] By adopting the above technical solution, the rotation of the threaded sleeve is supported and limited, thereby preventing the threaded sleeve from moving.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the multi-stage packaging equipment and the operation method thereof applied to the production of bulk bags can limit the position of the bulk bags when the multiple bulk bags are pressed together, thereby preventing the multiple bulk bags from being skewed during the pressing process due to the relatively smooth surface of the bulk bags, preventing the bulk bags from being scattered during the subsequent pressing process, and improving the bundling and packaging quality of the bulk bags; 1. When multiple bulk bags are pressed and bundled for packaging, multiple bulk bags are stacked on the top of the lower pressure plate, and then the upper pressure plate can be controlled to descend by the hydraulic push rod. During the descent process, the upper pressure plate drives the guide rod to slide on the fixed frame for limiting. During the movement process, the upper pressure plate can drive the U-shaped rod to move. After the U-shaped rod moves, it can drive the movable frame to move through the sliding connection with the movable frame, so that the movable rod slides on the fixed frame, and then during the descent process of the upper pressure plate, the two sets of movable frames limit the left and right sides of the stacked bulk bags. If the upper pressure plate needs to continue to move down after the movable frame contacts the bulk bag, the upper pressure plate continues to move down so that the movable frame no longer moves, so that the U-shaped rod can drive the movable block in the installation groove. The upper and lower pressure plates can slide and compress the telescopic spring, so that the upper pressure plate continues to move downward to press the multiple bulk bags with the lower pressure plate, which can reduce the volume of the multiple bulk bags. In order to prevent the bulk bags from recovering their deformation, the strapping belt can be passed through the through slot, and then the multiple bulk bags after pressing can be bundled and packaged by the strapping belt, so that the multiple packaging bags can be conveniently bundled and packaged after being stacked and pressed, which is convenient for multi-level packaging of the bulk bags, so that when pressing the multiple bulk bags, the bulk bags can be limited, which can prevent the multiple bulk bags from being skewed during the pressing process due to the relatively smooth surface of the bulk bags, and prevent the bulk bags from being scattered during the subsequent pressing process, thereby improving the bundling and packaging quality of the bulk bags; 2. The two sets of movable frames can drive the lower movable rod to move during the movement, and then drive the toothed plate to move. After the toothed plate moves, it can drive the rotating rod to rotate through the meshing rotating gear. After the rotating rod rotates, it can drive the turntable to rotate, and then the rubber rope can be rolled up, and then the sliding rod can be pulled to move through the rubber rope, so that the two sets of sliding rods are close to each other, and the reset spring can be stretched to make the two sets of limit plates close to each other, so that the two sets of limit plates move close to the container bag, and the front and back sides of the container bag can be limited, and the container bag can be further prevented from being skewed and scattered during the pressing process. If the upper pressing plate continues to move after the limit plate is attached to the container bag, the continued downward movement of the upper pressing plate can stretch the rubber rope. The rubber rope itself has a certain elastic force, and then the left and right sides of the container bag can be limited at the same time. The front and back sides of the container bag are limited to avoid the container bag from being skewed and affecting the packaging quality; 3. The rotating rod on the right side of the front can drive the active pulley to rotate during the rotation process. After the active pulley rotates, the driven pulley can be driven to rotate through the belt, so that the threaded sleeve rotates. During the rotation process, the threaded sleeve drives the fixed ring to slide on the limiting ring groove on the inner side of the limiting ring to prevent the threaded sleeve from moving. After the threaded sleeve rotates, it can drive the lower pressure plate to move downward through the threaded connection with the threaded rod. The lower pressure plate drives the positioning rod to slide on the base for limiting, so that the two sets of limiting plates can block the container bags on the lower pressure plate, so that the limiting plates can limit the container bags. Limiting, after the container bags are pressed and packed, the upper pressure plate is reset by the hydraulic push rod. At this time, the bundled container bags are placed on the top of the lower pressure plate. As the upper pressure plate is reset, the movable frame and the movable rod can be reset. After the movable rod is reset, it drives the rotating rod to rotate in the opposite direction, and then drives the lower pressure plate to rise, so that the top surface of the lower pressure plate is flush with the top surface of the limit plate, so that the limit plate no longer blocks the packaged container bags, avoiding the need to lift the container bags due to the obstruction of the limit plate, and thus facilitating the removal of the packaged container bags, thereby improving convenience and practicality.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The mounting grooves 201 on one side are divided into two groups. The insides of the two mounting grooves 201 in each group are slidably connected with movable blocks 202. A U-shaped rod 203 is fixedly installed on one side of the two movable blocks 202. Telescopic springs 204 are symmetrically sleeved on both sides of the outside of the U-shaped rod 203. At the same time, one end of the telescopic spring 204 is fixedly connected to the mounting groove 201, and the other end of the telescopic spring 204 is fixedly connected to the movable block 202. The movable rods 205 are symmetrically slidably connected to the two sides of the fixed frame 102. The movable rods are divided into two groups. A movable frame 206 is fixedly installed on one end of each group of two movable rods 205, and the U-shaped rod 203 is slidably connected to the movable frame 206. The upper end of the movable frame 206 is inclined, and the lower end of the movable frame 206 is vertically set. Moreover, a through groove 2061 is provided on one side of the movable frame 206 at the top of the upper pressure plate 104.

[0026] Embodiment 1: Figure 1-Figure 4 As shown, when multiple bulk bags are pressed and bundled for packaging, the multiple bulk bags are stacked on the top of the lower pressing plate 106, and then the upper pressing plate 104 can be controlled to descend by the hydraulic push rod 103. During the descent process, the upper pressing plate 104 drives the guide rod 105 to slide on the fixed frame 102 for limiting. During the movement process, the upper pressing plate 104 can drive the U-shaped rod 203 to move. After the U-shaped rod 203 moves, it can drive the movable frame 206 to move through the sliding connection with the movable frame 206, so that the movable rod 205 slides on the fixed frame 102, and then the upper pressing plate 104 causes the two groups of movable frames 206 to limit the left and right sides of the stacked bulk bags during the descent process. If the upper pressing plate 104 needs to continue to move downward after the movable frame 206 contacts the bulk bag, the upper pressing plate 104 continues to move downward so that the movable frame 206 no longer moves The U-shaped rod 203 can move so that the movable block 202 can slide inside the installation groove 201, and can compress the telescopic spring 204, so that the upper pressure plate 104 continues to move downward to press the multiple container bags with the lower pressure plate 106, which can reduce the volume of the multiple container bags. In order to prevent the container bags from recovering from deformation, the strapping belt can be passed through the through slot 107, and then the multiple container bags after pressing are bundled and packaged by the strapping belt, so that the multiple packaging bags can be conveniently bundled and packaged after being stacked and pressed, which is convenient for multi-level packaging of the container bags, so that when pressing the multiple container bags, the container bags can be limited, which can prevent the multiple container bags from being skewed during the pressing process due to the relatively smooth surface of the container bags, and prevent the container bags from being scattered during the subsequent pressing process, thereby improving the bundling and packaging quality of the container bags.

[0027] Positioning frames 207 are symmetrically installed on one side of the two groups of movable rods 205 at the bottom of the two sides of the fixed frame 102, and the insides of the two positioning frames 207 are rotatably connected to the rotating rods 208, and the outsides of the rotating rods 208 are rotatably connected to the connecting frames 209 at the bottom, and the connecting frames 209 are fixedly connected to the base 1; A tooth plate 210 is fixedly installed at one end of each group of lower movable rods 205 away from the movable frame 206, and a rotating gear 211 is fixedly installed on the outer upper part of the rotating rod 208, and the rotating gear 211 is meshed and connected with the tooth plate 210; A turntable 212 is fixedly installed on the outside of the two sets of rotating rods 208 above the connecting frame 209, and two sets of mounting frames 214 are symmetrically installed on both sides of the rear of the base 1, and a sliding rod 215 is slidably connected to the top of the mounting frame 214, and a limit plate 216 is fixedly installed on one end of the sliding rod 215; A return spring 217 is sleeved on one side of the outer portion of the two sets of sliding rods 215, and one end of the return spring 217 is fixedly connected to the mounting frame 214, and the other end of the return spring 217 is fixedly connected to the limit plate 216; A rubber rope 213 is fixedly installed on one side of the outer side of the two sets of rotating disks 212 , and one end of the two sets of rubber ropes 213 away from the rotating disks 212 is fixedly connected to the two sets of sliding rods 215 respectively.

[0028] Embodiment 2: Figure 1-Figure 2 and Figure 5-Figure 7 As shown, the two groups of movable frames 206 can drive the lower movable rod 205 to move during the movement, and then drive the toothed plate 210 to move. After the toothed plate 210 moves, it can drive the rotating rod 208 to rotate by meshing the rotating gear 211. After the rotating rod 208 rotates, it can drive the turntable 212 to rotate, and then the rubber rope 213 can be rolled up, and then the sliding rod 215 can be pulled to move by the rubber rope 213, so that the two groups of sliding rods 215 are close to each other, and the reset spring 217 can be stretched. The movement of the movable frame 206 will exert a certain reaction force on the U-shaped frame 203, and the telescopic spring 204 outside the U-shaped rod can The rod is supported, and the elastic potential energy of the telescopic spring 204 is greater than the elastic potential energy of the return spring 217, so that the two groups of limit plates 216 are close to each other, and the two groups of limit plates 216 are moved close to the container bag, which can limit the front and back sides of the container bag, and further prevent the container bag from tilting and scattering during the pressing process. If the upper pressure plate 104 continues to move after the limit plates 216 are fitted with the container bag, the continued downward movement of the upper pressure plate 104 can stretch the rubber rope 213. The rubber rope 213 itself has a certain elastic force, and thus while limiting the left and right sides of the container bag, it can also limit the front and back sides of the container bag, avoiding the container bag from tilting and affecting the packaging quality.

[0029] A threaded rod 219 is fixedly installed at the bottom of the lower pressure plate 106, and a through hole 220 is opened through the top center of the base 1, and positioning rods 221 are symmetrically installed on both sides of the bottom of the lower pressure plate 106, and the positioning rods 221 are slidably connected with the base 1, and the bottom end of the front right rotating rod 208 passes through the connecting frame 209 and is fixedly installed with a driving pulley 218, and a threaded sleeve 222 is sleeved on the outer lower part of the threaded rod 219, and a driven pulley 223 is fixedly installed on the outer lower part of the threaded sleeve 222, and the driven pulley 223 is rotationally connected with the driving pulley 218 through a belt; A fixing ring 224 is fixedly installed on the upper part of the outside of the threaded sleeve 222, and a limiting frame 225 is fixedly installed on the bottom of the base 1 above the threaded sleeve 222, and a limiting ring 226 is fixedly installed on the inner side of the limiting frame 225. At the same time, a limiting ring groove 227 is opened on the inner side of the limiting ring 226, and the fixing ring 224 is slidably connected with the limiting ring groove 227.

[0030] Embodiment 3: Figure 1-Figure 2 and Figure 8-Figure 9 As shown, the front right rotating rod 208 can drive the active pulley 218 to rotate during the rotation process. After the active pulley 218 rotates, the driven pulley 223 can be driven to rotate through the belt, so that the threaded sleeve 222 rotates. During the rotation process, the threaded sleeve 222 drives the fixing ring 224 to slide on the limiting ring groove 227 on the inner side of the limiting ring 226 to prevent the threaded sleeve 222 from moving. After the threaded sleeve 222 rotates, it can drive the lower pressure plate 106 to move downward through the threaded connection with the threaded rod 219. The lower pressure plate 106 drives the positioning rod 221 to slide on the base 1 for limiting, so that the two sets of limiting plates 216 can block the container bag on the lower pressure plate 106, so that the limiting plate 21 6 can limit the container bag. After the container bag is pressed and packaged, the upper pressure plate 104 is reset by the hydraulic push rod 103. At this time, the bundled container bag is placed on the top of the lower pressure plate 106. As the upper pressure plate 104 is reset, the movable frame 206 and the movable rod 205 can be reset. After the movable rod 205 is reset, it drives the rotating rod 208 to rotate in the opposite direction, thereby driving the lower pressure plate 106 to rise, so that the top surface of the lower pressure plate 106 is flush with the top surface of the limiting plate 216, so that the limiting plate 216 no longer blocks the packaged container bag, avoiding the need to lift the container bag due to the blocking of the limiting plate 216, thereby facilitating the removal of the packaged container bag, thereby improving convenience and practicality.

[0031] Working principle: When using the multi-stage packaging equipment for container bag production, first, according to Figure 1-Figure 9As shown, multiple bulk bags are stacked on the top of the lower pressure plate 106, and then the upper pressure plate 104 can be controlled to descend by the hydraulic push rod 103. During the descent process, the upper pressure plate 104 drives the guide rod 105 to slide on the fixed frame 102 for limiting. During the movement process, the upper pressure plate 104 can drive the U-shaped rod 203 to move. After the U-shaped rod 203 moves, it can drive the movable frame 206 to move through the sliding connection with the movable frame 206, so that the movable rod 205 slides on the fixed frame 102, and then the upper pressure plate 104 causes the two groups of movable frames 206 to move the left and right sides of the stacked bulk bags during the descent process. If the upper pressing plate 104 needs to continue to move downward after the movable frame 206 contacts the container bag, the upper pressing plate 104 continues to move downward so that the movable frame 206 does not move, so that the U-shaped rod 203 can drive the movable block 202 to slide inside the installation groove 201, and can compress the telescopic spring 204, so that the upper pressing plate 104 continues to move downward to press the multiple container bags with the lower pressing plate 106, which can reduce the volume of the multiple container bags. In order to prevent the container bag from recovering its deformation, the strapping belt can be passed through the through slot 107, and then the multiple container bags after pressing are bundled and packaged by the strapping belt; The two groups of movable frames 206 can drive the lower movable rod 205 to move during the movement, and then drive the toothed plate 210 to move. After the toothed plate 210 moves, it can drive the rotating rod 208 to rotate by meshing the rotating gear 211. After the rotating rod 208 rotates, it can drive the rotating disk 212 to rotate, and then the rubber rope 213 can be rolled up, and then the sliding rod 215 can be pulled to move by the rubber rope 213, so that the two groups of sliding rods 215 are close to each other, and the reset spring 215 can be stretched. 17, so that the two groups of limiting plates 216 are close to each other, so that the two groups of limiting plates 216 move close to the container bag, the front and rear sides of the container bag can be limited, and the container bag can be further prevented from being skewed and scattered during the pressing process. The front right rotating rod 208 can drive the active pulley 218 to rotate during the rotation process. After the active pulley 218 rotates, the driven pulley 223 can be driven to rotate through the belt, so that the threaded sleeve 222 rotates. During the rotation process, the threaded sleeve 222 drives the fixing ring 224 on the inner side of the limiting ring 226 The limiting ring groove 227 slides to prevent the threaded sleeve 222 from moving. After the threaded sleeve 222 rotates, it can drive the lower pressure plate 106 to move downward through the threaded connection with the threaded rod 219. The lower pressure plate 106 drives the positioning rod 221 to slide on the base 1 for limiting, so that the two sets of limiting plates 216 can block the container bags on the lower pressure plate 106, so that the limiting plates 216 can limit the container bags. After the container bags are pressed and packaged, the upper pressure plate 104 is reset by the hydraulic push rod 103. At this time, the bundled The bag is placed on the top of the lower pressure plate 106. As the upper pressure plate 104 is reset, the movable frame 206 and the movable rod 205 can be reset. After the movable rod 205 is reset, it drives the rotating rod 208 to rotate in the opposite direction, thereby driving the lower pressure plate 106 to rise, so that the top surface of the lower pressure plate 106 is flush with the top surface of the limiting plate 216, so that the limiting plate 216 no longer blocks the packaged container bag, avoiding the need to lift the container bag due to the obstruction of the limiting plate 216, thereby facilitating the removal of the packaged container bag.

9. An operating method of a multi-stage packaging device used in the production of bulk bags, using the multi-stage packaging device used in the production of bulk bags as claimed in any one of claims 1 to 8, the specific operating method is as follows; Step 1: When a plurality of bulk bags are pressed and bundled for packaging, the plurality of bulk bags are stacked on top of the lower pressing plate (106), and then the upper pressing plate (104) is controlled to descend by the hydraulic push rod (103). During the descent process, the upper pressing plate (104) drives the guide rod (105) to slide on the fixed frame (102) to limit the position. During the movement process, the upper pressing plate (104) drives the U-shaped rod (203) to move. After the U-shaped rod (203) moves, The sliding connection with the movable frame (206) drives the movable frame (206) to move, so that the movable rod (205) slides on the fixed frame (102), and then the upper pressure plate (104) causes the two sets of movable frames (206) to limit the left and right sides of the stacked container bags during the descending process. If the upper pressure plate (104) needs to continue to move downward after the movable frame (206) contacts the container bag, the upper pressure plate (104) continues to move downward so that the movable frame (206) The U-shaped rod (203) no longer moves. At this time, the U-shaped rod (203) is at the inclined position of the movable frame (206), so that the U-shaped rod (203) drives the movable block (202) to slide inside the installation groove (201) and compresses the telescopic spring (204), thereby causing the upper pressing plate (104) to continue to move downward to press the multiple container bags with the lower pressing plate (106), thereby reducing the volume of the multiple container bags. In order to prevent the container bags from recovering from deformation, the strapping belt is passed through the through slot (107), and then the multiple container bags after pressing are bundled and packaged by the strapping belt, so that the multiple packaging bags can be conveniently bundled and packaged after being stacked and pressed, and the container bags are convenient for multi-level packaging. When the multiple container bags are pressed, the container bags are limited to avoid being skewed during the pressing process due to the relatively smooth surface of the container bags, and the container bags are prevented from being scattered during the subsequent pressing process, thereby improving the bundling and packaging quality of the container bags; Step 2: The two groups of movable frames (206) drive the lower movable rod (205) to move during the movement, thereby driving the toothed plate (210) to move. After the toothed plate (210) moves, it drives the rotating rod (208) to rotate by meshing with the rotating gear (211). After the rotating rod (208) rotates, it drives the rotating disk (212) to rotate, thereby winding the rubber rope (213). Then, the sliding rod (215) is pulled to move by the rubber rope (213), so that the two groups of sliding rods (215) are close to each other, and the return spring (217) is stretched, so that the two groups of sliding rods (215) are close to each other. The two groups of limiting plates (216) are moved close to each other, so that the two groups of limiting plates (216) move close to the container bag, and limit the front and rear sides of the container bag, further preventing the container bag from being skewed and scattered during the pressing process. If the upper pressing plate (104) continues to move after the limiting plates (216) are attached to the container bag, the upper pressing plate (104) continues to move downward to stretch the rubber rope (213). The elastic force of the rubber rope (213) limits the front and rear sides of the container bag while limiting the left and right sides of the container bag, thereby preventing the container bag from being skewed and affecting the packaging quality. Step 3: The front right rotating rod (208) drives the driving pulley (218) to rotate during the rotation process. After the driving pulley (218) rotates, the driven pulley (223) is driven to rotate through the belt, so that the threaded sleeve (222) rotates. During the rotation process, the threaded sleeve (222) drives the fixing ring (224) to slide on the limiting ring groove (227) inside the limiting ring (226) to prevent the threaded sleeve (222) from moving. After the threaded sleeve (222) rotates, it drives the lower pressure plate (106) to move downward through the threaded connection with the threaded rod (219). The lower pressure plate (106) drives the positioning rod (221) to slide on the base (1) to limit the position, so that the two sets of limiting plates (216) cover the container bag on the lower pressure plate (106), so that the limiting plate (21 6) Limiting the container bag. After the container bag is pressed and packed, the upper pressure plate (104) is reset by the hydraulic push rod (103). At this time, the bundled container bag is placed on the top of the lower pressure plate (106). As the upper pressure plate (104) is reset, the movable frame (206) and the movable rod (205) are reset. After the movable rod (205) is reset, it drives the rotating rod (208) to rotate in the opposite direction, thereby driving the lower pressure plate (106) to rise, so that the top surface of the lower pressure plate (106) is flush with the top surface of the limiting plate (216), so that the limiting plate (216) no longer blocks the packaged container bag, avoiding the need to lift the container bag due to the blocking of the limiting plate (216), thereby facilitating the removal of the packaged container bag, thereby improving convenience and practicality.
