Description

Technical Field

[0001] This utility model relates to the field of bagging equipment, specifically a pre-bulging device for bulk salt bags. Background Technology

[0002] The bulk salt bag pre-bulging equipment is an automated auxiliary device that pre-expands empty bags before filling. Its core function is to ensure that the packaging bag is fully expanded, effectively preventing uneven filling, weight deviation or bag breakage caused by bag wall adhesion, thereby significantly improving bagging efficiency and packaging qualification rate. It can also significantly reduce packaging defects caused by bag wrinkles and adhesion.

[0003] In existing technology, a bulk salt machine is an automated device used to automatically measure bulk salt and discharge it through a discharge port. When discharging salt, it is usually directly discharged into packaging bags. However, in some places, in order to save costs, the packaging bags are usually manually opened and placed under the salt discharge port, or simple instruments such as manual lever bag openers are used to open the packaging bags. Although this method can effectively open the packaging bags and fill them through the salt outlet, manually opening the packaging bags may result in uneven opening of the bag opening, which may easily lead to filling spillage or weight errors. The manual lever bag opener requires the operator to step on a pedal or pull a switch to drive it. Due to inconsistent force when stepping or pulling, the bag opening may be opened to different sizes, which may lead to weight errors and reduce work efficiency. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, manually opening packaging bags may result in uneven opening of the bag opening, which can easily lead to filling spillage or weight errors. Manual lever-type bag openers require workers to step on a pedal or pull a switch to drive them, which may cause the bag opening to open in different sizes due to inconsistent force each time the pedal is stepped or pulled, which may lead to weight errors and reduce work efficiency. This utility model proposes a pre-bulging support device for bulk salt bags.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a pre-bulging device for bagged salt, including a salt dispensing machine body, a discharge port is provided on one side of the salt dispensing machine body, a worktable is provided on one side of the discharge port, an installation plate is fixedly connected to the top of the worktable, a servo motor is fixedly connected to the inner cavity of the installation plate, the output end of the servo motor passes through one side of the installation plate, and a spreading mechanism is provided at the bottom of the servo motor. The spreading mechanism includes a rotating column, one end of which is fixedly connected to the output end of a servo motor. A gear is fixedly connected to the surface of the rotating column, and the bottom of the gear is rotatably connected to the top of the worktable. Two racks are slidably connected to the surface of the worktable, and the teeth of both racks mesh with the teeth of the gear. An L-shaped block is fixedly connected to the top of each of the two racks. A connecting block is movably engaged on one side of each of the two L-shaped blocks. A spreading plate is fixedly connected to one side of each of the two connecting blocks. A support assembly is provided at the bottom of the worktable.

[0006] Preferably, the support assembly includes a hollow block, the inner cavity of which is threadedly connected to the surface of the rotating column. A connecting rod is fixedly connected to one side of the hollow block, and a mounting block is fixedly connected to one end of the connecting rod. A spring is fixedly connected to the top of the mounting block, and a support block is fixedly connected to one end of the spring. A connecting side plate is fixedly connected to the bottom of the workbench, and one side of the connecting side plate is slidably connected to one side of the hollow block.

[0007] Preferably, a telescopic rod is fixedly connected to the top of the mounting block, a spring is sleeved on the surface of the telescopic rod, and one end of the telescopic rod is fixedly connected to the bottom of the support block.

[0008] Preferably, each of the two L-shaped blocks has a slot on one side, and each of the two connecting blocks has a locking block fixedly connected to one side, with the surface of the locking block movably engaging with the inner cavity of the slot.

[0009] Preferably, a limiting block is fixedly connected to one side of the hollow block, and a limiting groove is formed on one side of the inner cavity of the connecting side plate, with the surface of the limiting block slidingly connected to the inner cavity of the limiting groove.

[0010] Preferably, the top of the workbench is provided with a plug-in hole, and multiple plug-in holes are provided, one of which has a plug-in block movably inserted into its inner cavity.

[0011] Preferably, one end of the rotating column is fixedly connected to a limiting ring block, and a rubber plate is movably bonded to one side of the support block.

[0012] The advantages of this utility model are: This invention involves pouring salt into the body of a salt dispensing machine and simultaneously discharging it through a discharge port. Before the salt is discharged, workers can place a packaging bag on the surface of the expansion plate and support it with a support block. At the same time, a servo motor is activated, which drives the expansion plate to move, thus pre-inflating the packaging bag. This expansion mechanism saves time compared to manual bag opening and reduces the labor intensity of workers. It also reduces the risk of bag tearing or damage due to improper force control. This solves the problem that manual bag opening may result in uneven bag opening, leading to spillage or weight errors during filling. Manual lever-type bag openers require workers to step on a pedal or pull a switch, which can cause inconsistent bag openings due to varying force, potentially resulting in weight errors and reduced work efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses a pre-bulging device for bulk salt bags. (Refer to...) Figure 1 and Figure 2 A pre-bulging support device for bulk salt bagging includes a bulk salt machine body 1, a discharge port 2 on one side of the bulk salt machine body 1, a workbench 3 on one side of the discharge port 2, a mounting plate 4 fixedly connected to the top of the workbench 3, a servo motor 5 fixedly connected to the inner cavity of the mounting plate 4, the output end of the servo motor 5 passing through one side of the mounting plate 4, and a support mechanism 6 at the bottom of the servo motor 5. The spreading mechanism 6 includes a rotating column 601, one end of which is fixedly connected to the output end of the servo motor 5. A gear 602 is fixedly connected to the surface of the rotating column 601. The bottom of the gear 602 is rotatably connected to the top of the worktable 3. A rack 603 is slidably connected to the surface of the worktable 3. Two racks 603 are provided, and the teeth of the two racks 603 mesh with the teeth of the gear 602. An L-shaped block 604 is fixedly connected to the top of each of the two racks 603. A connecting block 605 is movably engaged on one side of each of the two L-shaped blocks 604. A spreading plate 606 is fixedly connected to one side of each of the two connecting blocks 605. A support assembly 607 is provided at the bottom of the worktable 3.

[0018] The salt dispensing machine body 1 can efficiently and accurately complete the quantitative discharge process of salt products. It is a key machine for achieving large-scale production and ensuring product weight consistency. Since the salt dispensing machine body 1 is existing technology in this field, it will not be described in detail here. Workers can pour salt into the salt dispensing machine body 1. After the salt dispensing machine body 1 completes its operation, the salt will be discharged through the discharge port 2. Workers can place the packaging table on the surface of the opening mechanism 6 and use the opening mechanism 6 to open the packaging bag, allowing the salt discharged from the discharge port 2 to fall smoothly into the packaging bag. The worktable 3 connects to the mounting plate 4 to provide a connection for the servo motor 5. The servo motor 5 is also connected to the rotating column 601. The worktable 3 provides installation and connection for the gear 602 and rack 603. The teeth of the gear 602 mesh with the teeth of the rotating column 601. Workers can start the servo motor 5 and... The operation of component 5 drives the rotating column 601 and gear 602 to rotate. When gear 602 starts to rotate, it drives two racks 603 to move in opposite directions simultaneously. The two racks 603 are connected to two L-shaped blocks 604, and the two L-shaped blocks 604 are of different lengths. The shorter L-shaped block 604 is connected to the rack 603 on the side closer to the outlet 2, while the longer L-shaped block 604 is connected to the rack 603 on the other side. The two L-shaped blocks 604 are connected to the two expansion plates 606 through the connection with two connecting blocks 605, so that when the two racks 603 move in opposite directions, they will drive the two expansion plates 606 to move in opposite directions synchronously. The staff can put the packaging bag on the surface of the two expansion plates 606. When the two expansion plates 606 move, they will open the packaging bag and support it through the support component 607 below the equipment, thus achieving pre-support of the packaging bag.

[0019] Reference Figure 3 and Figure 4The support assembly 607 includes a hollow block 6071. The inner cavity of the hollow block 6071 is threadedly connected to the surface of the rotating column 601. A connecting rod 6072 is fixedly connected to one side of the hollow block 6071. A mounting block 6073 is fixedly connected to one end of the connecting rod 6072. A spring 6074 is fixedly connected to the top of the mounting block 6073. A support block 6075 is fixedly connected to one end of the spring 6074. A connecting side plate 6076 is fixedly connected to the bottom of the worktable 3. One side of the connecting side plate 6076 is slidably connected to one side of the hollow block 6071. The rotating column 601 provides a connection for the connecting rod 6072 through its connection with the hollow block 6071. The connecting rod 6072 is connected to the mounting block 6073. When the rotating column 601 starts to rotate, the hollow block 6071, the connecting rod 6072, and the mounting block 6073 move up and down along the surface of the rotating column 601. 73 connects to the support block 6075 via the spring 6074. When the mounting block 6073 moves upward, the spring 6074 pushes the support block 6075 upward synchronously. The support block 6075 supports the packaging bag fitted on the surface of the expansion plate 606, preventing the packaging bag from slipping or spilling. Simultaneously, the spring 6074 allows the packaging bag to slowly sink as the amount of salt inside increases during filling at the outlet 2, causing the expansion plate 606 to slowly move from the innermost part of the packaging bag to the bag opening. This prevents the expansion plate 606 from affecting the internal capacity of the packaging bag. After filling, the expansion plate 606 resets under the action of the rotating column 601, simultaneously causing the support block 6075 to move downward, making it easier for workers to remove the filled packaging bag.

[0020] Reference Figure 3 and Figure 6 A telescopic rod 7 is fixedly connected to the top of the mounting block 6073. A spring 6074 is sleeved on the surface of the telescopic rod 7. One end of the telescopic rod 7 is fixedly connected to the bottom of the support block 6075. The mounting block 6073 provides installation and connection for the telescopic rod 7. At the same time, the telescopic rod 7 is connected to the support block 6075. The setting of the telescopic rod 7 can provide a certain connection for the support block 6075, and can also play a certain limiting role for the spring 6074. This makes it less likely that the spring 6074 will undergo excessive deformation when it elastically returns to its original state after the staff removes the packaging bag placed on the surface of the support block 6075, thereby improving the service life of the spring 6074 to a certain extent.

[0021] Reference Figure 5Each of the two L-shaped blocks 604 has a slot 9 on one side, and each of the two connecting blocks 605 has a fixed block 8 on one side. The surface of the block 8 is movably engaged with the inner cavity of the slot 9, and one side of the connecting block 605 is connected to the block 8. The slot 9 on one side of the L-shaped block 604 allows the block 8 and the slot 9 to engage with each other, making it easier to disassemble or replace the support plate 606. At the same time, when pre-supporting packaging bags of different sizes is required, the staff can replace the support plate 606 of different sizes according to the size of the packaging bag, thereby increasing the adaptability of the support mechanism 6.

[0022] Reference Figure 3 and Figure 4 A limiting block 10 is fixedly connected to one side of the hollow block 6071. A limiting groove 11 is opened on one side of the inner cavity of the connecting side plate 6076. The surface of the limiting block 10 is slidably connected to the inner cavity of the limiting groove 11. The hollow block 6071 is connected to the limiting block 10. By opening the limiting groove 11 on one side of the connecting side plate 6076, the limiting block 10 can slide inside the limiting groove 11. The limiting block 10 can provide a limiting function for the hollow block 6071, so that the hollow block 6071 can move more smoothly and is less likely to deviate.

[0023] Reference Figure 2 The top of the workbench 3 is provided with a plurality of insertion holes 12. An insertion block 13 is movably inserted into the inner cavity of one of the insertion holes 12. The insertion hole 12 is connected to the insertion block 13. The operator can determine the distance that the support component 607 needs to move according to the size of the packaging bag, and then insert the insertion block 13 into the appropriate insertion hole 12. The insertion block 13 can block the rack 603, so that when the servo motor 5 stops rotating, its residual rotation is not likely to continue to drive the rack 603 to move, which may lead to damage to the packaging bag.

[0024] Reference Figure 3 One end of the rotating column 601 is fixedly connected to a limiting ring block 15, and a rubber plate 14 is movably bonded to one side of the support block 6075. The rotating column 601 is connected to the limiting ring block 15, and the support block 6075 is connected to the rubber plate 14. The limiting ring block 15 can limit the hollow block 6071, so that the hollow block 6071 is not easy to detach from the contact with the rotating column 601 when it moves, thus preventing it from slipping. The rubber plate 14 can increase the friction between the support block 6075 and the packaging bag, making it less likely for the packaging bag to slip or tilt, so that the support block 6075 can be used more smoothly.

[0025] Working Principle: Before using this device, the operator needs to place the packaging bag on the surface of the expansion plate 606. Simultaneously, the servo motor 5 can be started, driving the rotating column 601 and gear 602 to rotate. When gear 602 starts rotating, it drives two racks 603 to move simultaneously in opposite directions. When the two racks 603 move in opposite directions, they drive the two expansion plates 606 to move synchronously in opposite directions. The operator can then place the packaging bag on the surface of the two expansion plates 606. As the two expansion plates 606 move, they expand the packaging bag. When the rotating column 601 starts rotating, it causes the hollow block 6071, connecting rod 6072, and mounting block 6073 to move up and down along the surface of the rotating column 601. When the mounting block 6073 moves upward, it will be activated by the spring 6071. 74. The support block 6075 is pushed upward synchronously, and the support block 6075 can support the packaging bag on the surface of the expansion plate 606, so that the packaging bag on the surface of the expansion plate 606 is less likely to slip or spill. At this time, the salt inside the salt dispensing machine body 1 can be discharged through the discharge port 2, and the packaging bag placed on the surface of the support block 6075 can be filled. After filling is completed, the expansion plate 606 will be reset under the drive of the rotating column 601, and the support block 6075 will be moved downward. At this time, the workers can remove the packaging bag on the surface of the support block 6075. The setting of the expansion mechanism 6 improves the work efficiency to a certain extent, reduces the labor intensity of the workers, and reduces the occurrence of packaging bag tearing or damage due to improper force control.
