[0002] In today's chemical and other fields, ton bag specifications are widely used for various products. The weight of ton bag products requires precise control, and traditionally, during the re-inspection process, manual adjustments are typically made by adding or removing materials to correct deviations and ensure that the final weight of the ton bag meets the standard requirements.

[0003] Under these circumstances, a single ton bag production line requires 1-2 people to perform deviation correction work in the re-inspection process.

[0029] 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 protection scope of the present utility model.

[0030] The purpose of this invention is to provide a device for correcting out-of-tolerance issues in the re-inspection process of ton-bag products, in order to solve the problems existing in the prior art. By setting up a replenishment bin and a quantitative feeding mechanism, the device can replenish the weight of the ton-bag products by adding material, and by setting up a negative pressure power mechanism, it can suck up the material to reduce the weight of the ton-bag products, thereby correcting the out-of-tolerance issues of the ton-bag products and making the weight of the ton-bag products meet the standard requirements. This greatly saves labor costs and can improve the correction efficiency and accuracy.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-6As shown, this embodiment provides a device for correcting deviations in the re-inspection process of ton-bag products, including a replenishment bin 1, a correction pipeline 2, and a gas-solid separation mechanism 3. A quantitative conveying mechanism 4 is provided at the discharge port of the replenishment bin 1. The correction pipeline 2 is vertically arranged, either vertically or at a small angle to the vertical direction. The inlet of the correction pipeline 2 is connected to the outlet of the quantitative conveying mechanism 4 via a weighting pipeline 7. The outlet of the correction pipeline 2 is directed towards and close to the material surface of the ton-bag product 5 (ton-bag product 5). (Including packaging bags and materials inside the packaging bags); the air intake of the gas-solid separation mechanism 3 is connected to the feed inlet of the correction pipeline 2 through the weight reduction pipeline 8; the exhaust port of the gas-solid separation mechanism 3 is connected to the negative pressure power mechanism 6, which can be a negative pressure pump. The gas-solid separation mechanism 3 is used to separate gas and solid. Specifically, the gas-solid separation mechanism 3 may include a cavity, the air intake of the cavity is connected to the weight reduction pipeline 8, the exhaust port of the cavity is connected to the negative pressure pump, and a filter screen for filtering filter media is provided at the exhaust port of the cavity. The "feed inlet of the correction pipeline 2" mentioned here refers to the top opening of the correction pipeline 2, and the "discharge port of the correction pipeline 2" refers to the bottom opening of the correction pipeline 2.

[0033] In use, place the ton bag product 5 on the weighing mechanism. The outlet of the correction pipe 2 is located above the ton bag product 5 and close to the material surface of the ton bag product 5. The weight of the ton bag product 5 is adjusted based on the weighing result displayed by the weighing mechanism. To increase the weight of the ton bag product 5, activate the quantitative feeding mechanism 4, adding material to the ton bag product 5 through the weight-increasing pipe 7 and the correction pipe 2 until the weighing mechanism displays that the weight of the ton bag product 5 reaches the standard. To decrease the weight of the ton bag product 5, activate the negative pressure pump. The negative pressure pump draws a portion of the material from the ton bag product 5 into the gas-solid separation mechanism 3 through the weight-reducing pipe 8 and the correction pipe 2. The solid material is separated and falls into the cavity of the gas-solid separation mechanism 3 until the weighing mechanism displays that the weight of the ton bag product 5 reaches the standard.

[0034] In this embodiment, the ton-bag product 5 can be a material that is easily adsorbed by negative pressure, such as granular material.

[0035] Therefore, this embodiment can add material to increase the weight of the ton bag product 5 by setting up the replenishment bin 1 and the quantitative conveying mechanism 4, and can suck up material to reduce the weight of the ton bag product 5 by setting up the negative pressure power mechanism 6. This realizes the correction of the deviation of the ton bag product 5 by using mechanical equipment, so that the weight of the ton bag product 5 meets the standard requirements, thereby greatly saving labor costs and improving correction efficiency and accuracy. Moreover, the weight increase and weight reduction methods in this embodiment are simple, have low manufacturing costs, and are easy to implement and promote.

[0036] As one embodiment, the bottom of the cavity in the gas-solid separation mechanism 3 is a conical structure, and a discharge port is provided at the bottom of the conical structure. The discharge port is connected to the feed hopper 1 through the discharge valve 9, so that the material can enter the feed hopper 1 for reuse. This embodiment also includes a weighing mechanism, which is used to place the ton bag product 5 and has a digital display function. The weighing mechanism can be any commonly used equipment for weighing the ton bag product 5.

[0037] In one embodiment, a level gauge 10 for detecting the internal material level is installed inside the replenishment hopper 1. The top of the replenishment hopper 1 is connected to a replenishment mechanism via a replenishment pipeline, which can be a storage hopper. A replenishment valve 11 is installed on the replenishment pipeline, and the level gauge 10 is communicatively connected to the replenishment valve 11. When the level gauge 10 detects that the material level in the replenishment hopper 1 is lower than a set value, the replenishment valve 11 opens, replenishing material into the replenishment hopper 1.

[0038] In one embodiment, the quantitative feeding mechanism 4 includes a conveying channel, a first rotary power mechanism, and a screw quantitative conveying shaft. The screw quantitative conveying shaft includes a cylindrical shaft and auger blades mounted on the shaft. The first rotary power mechanism is fixed outside the conveying channel, and the screw quantitative conveying shaft is located inside the conveying channel. The output end of the first rotary power mechanism is fixedly connected to the screw quantitative conveying shaft. The end of the conveying channel is connected to a weight-adding pipeline 7. The first rotary power mechanism may include a first rotary motor and a first reducer. The output end of the first reducer is connected to the screw quantitative conveying shaft. The auger blades push the material into the weight-adding pipeline 7, and then it falls into the ton bag product 5 through the correction pipeline 2.

[0039] Dust may be generated during the material replenishment and weight gain process, which can pollute the working environment and be detrimental to the health of workers. To solve this technical problem, this embodiment includes a dust removal pipeline 12. The air intake of the dust removal pipeline 12 faces the ton bag product 5. Specifically, the air intake of the dust removal pipeline 12 is close to and above the discharge port of the correction pipeline 2. The exhaust port of the dust removal pipeline 12 is connected to the air intake of the gas-solid separation mechanism 3. This air intake can be the same as the air intake of the weight reduction pipeline 8, or there can be two separate ports. A dust removal valve 13 is provided between the dust removal pipeline 12 and the air intake of the gas-solid separation mechanism 3, and a weight reduction valve 14 is provided between the weight reduction pipeline 8 and the air intake of the gas-solid separation mechanism 3. When the weight of the ton bag product 5 needs to be reduced, the weight reduction valve 14 is opened and the dust removal valve 13 is closed, and the material is sucked in using the correction pipeline 2; when the weight of the ton bag product 5 needs to be increased, the weight reduction valve 14 is closed and the dust removal valve 13 is opened, and the material is added using the correction pipeline 2, while the dust removal pipeline 12 is used for dust removal.

[0040] Those skilled in the art should understand that if a filter screen is installed in the gas-solid separation mechanism 3, the filter screen should be used to filter the material. If the ton bag product 5 is a powder, and the dust drawn in during the weight gain process is mostly product material, then the filter screen should have the functions of filtering dust and exhausting gas; if the ton bag product 5 is particulate matter, and the dust drawn in during the weight gain process is mostly dust, then the filter screen should have the functions of filtering material and exhausting gas and dust.

[0041] To improve dust removal efficiency, a flared structure 17 is provided at the bottom of the dust removal pipeline 12 in this embodiment to increase the dust removal area. The flared structure 17 is fitted onto the outside of the correction pipeline 2, and the opening of the flared structure 17 is higher than the material discharge port of the correction pipeline 2 to avoid directly sucking the ton bag product 5 through the flared mouth, which would cause difficulties in weight adjustment.

[0042] As one embodiment, this embodiment also includes a lifting mechanism 19, the lifting end of which is fixedly connected to the bottom of the correction pipe 2 and the dust removal pipe 12. The lifting mechanism 19 is used to adjust the height of the correction pipe 2 and the dust removal pipe 12, controlling whether their bottom ends are entering or exiting the bag, and can also adapt to ton bags 5 of different heights; at the same time, when no correction operation is being performed, the correction pipe 2 and the dust removal pipe 12 can be raised. The bottom outlet of the correction pipe 2 is usually 3cm to 5cm away from the material surface of the ton bag product 5, while the bottom suction port of the dust removal pipe 12 is usually 5cm to 10cm away from the material surface of the ton bag product 5.

[0043] Specifically, the lifting mechanism 19 includes a second rotary power mechanism, a lead screw 22, and a threaded sleeve 23 fixed on the lead screw 22. The second rotary power mechanism includes a second rotary motor 20 and a second reducer 21 connected by a transmission connection. The output end of the second reducer 21 is fixedly connected to the end of the lead screw 22. The lead screw 22 is vertically arranged, and both ends are rotatably connected to the bearing seats 27. The threaded sleeve 23 is fixedly connected to the bottom of the correction pipe 2 and the dust removal pipe 12 through a connecting plate 24. The correction pipe 2 can be fixedly connected to the bottom of the dust removal pipe 12. When the two are fixedly connected, the connecting plate 24 can be connected to either the correction pipe 2 or the dust removal pipe 12. The lifting mechanism 19 also includes a vertically arranged baffle 25. A limit groove 26 is vertically arranged on the baffle 25. The connecting plate 24 passes through the limit groove 26 and is connected to the bottom of the correction pipe 2 and the dust removal pipe 12. The limiting groove 26 can only restrict the vertical movement of the connecting plate 24, thereby preventing the threaded sleeve 23 from rotating with the lead screw, so that the threaded sleeve 23 can drive the connecting plate 24 to move vertically and adjust the height of the correction pipe 2 and the dust removal pipe 12.

[0044] During the lifting and lowering process, the correction pipe 2 and the dust removal pipe 12 will cause the corresponding pipe bodies to move. To avoid repeated movement of the pipe bodies, in this embodiment, the weight-increasing pipe 7 and the weight-reducing pipe 8 are both connected to the feed inlet of the correction pipe 2 through the first spiral telescopic pipe section 15. After the first spiral telescopic pipe section 15 is set, the weight-increasing pipe 7 and the weight-reducing pipe 8 can be fixedly set. The dust removal pipe 12 is provided with a second spiral telescopic pipe section 16. The second spiral telescopic pipe section 16 is located above the connection position of the dust removal pipe 12 (the connection position between the dust removal pipe 12 and the correction pipe 2 or the connection position between the dust removal pipe 12 and the connecting plate 24), and is located between this connection position and the dust removal valve 13; the second spiral telescopic pipe section 16 should be as close as possible to this connection position to facilitate the fixed setting of the pipe section between this connection position and the gas-solid separation mechanism 3. When the correction pipe 2 and the dust removal pipe 12 descend under the drive of the lifting mechanism 19, the first spiral telescopic pipe section 15 and the second spiral telescopic pipe section 16 extend. When the correction pipe 2 and the dust removal pipe 12 rise under the drive of the lifting mechanism 19, the first spiral telescopic pipe section 15 and the second spiral telescopic pipe section 16 shorten.

[0045] To facilitate control of the lifting height of the lifting mechanism 19, a bottom contact monitoring mechanism 18 is also provided at the bottom of the correction pipe 2 in this embodiment. The bottom contact monitoring mechanism 18 is used to monitor the distance from the outlet of the correction pipe 2 to the surface of the ton bag product 5. The bottom contact monitoring mechanism 18 can be in contact or non-contact mode. When the monitoring mode is contact, the detection end of the bottom contact monitoring mechanism 18 is located 3cm to 5cm below the outlet of the correction pipe 2. When the detection end contacts the surface of the ton bag product 5, the bottom contact monitoring mechanism 18 sends a signal to control the lifting end of the lifting mechanism 19 to stop descending. When the monitoring mode is non-contact, the bottom contact monitoring mechanism 18 may include a distance measuring sensor. Given the known height difference between the detection end and the outlet of the correction pipe 2, when the detection end detects that its distance from the surface of the ton bag product 5 has fallen to a set distance, it controls the lifting end of the lifting mechanism 19 to stop descending.

[0046] Whether the bottoming detection mechanism 18 adopts a contact or non-contact type, there are corresponding devices in the prior art, and the specific selection of such devices will not be described in detail in this embodiment.

[0047] This embodiment also includes a control system, which is communicatively connected to the first rotary power mechanism, the second rotary power mechanism, the level gauge 10, the feeding valve 11, the unloading valve 9, the negative pressure pump, the dust removal valve 13, the weight reduction valve 14, and the bottom-contact monitoring mechanism 18, etc., and is used to control the normal operation of the out-of-tolerance correction device in the ton-bag product re-inspection process. The setting of the control system is a technology well known to those skilled in the art, and will not be described in detail in this embodiment.

[0048] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0049] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
