Description

Technical Field

[0001] This utility model relates to the field of ton bag technology, and in particular to a ton bag that is easy to unload. Background Technology

[0002] BOOM bags are commonly used in the chemical, building materials, and grain industries for packaging and transporting bulk powders and granules. Currently, BOOM bags on the market typically consist of a bag body with a discharge port at the bottom for unloading. In actual unloading operations, existing BOOM bags require manual untying of the pre-tied ropes at the discharge port to open it. After the material is unloaded, the discharge port must be tied back tightly with the ropes to close it. This manual untying method is not only cumbersome and time-consuming, but it also significantly reduces unloading efficiency, especially when unloading is frequent or when handling large quantities of BOOM bags. Furthermore, the tightness of the manual tying is difficult to control, which may result in incomplete sealing after unloading. Utility Model Content

[0003] The purpose of this invention is to provide a ton bag that is easy to unload, solving the technical problem that existing ton bags require manual untying of the outlet binding rope to open the outlet and re-tightening the binding rope to close the outlet, resulting in cumbersome operation and low unloading efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a ton bag for easy unloading, comprising a bag body, a fixing ring, a feeding ring and a locking pin;

The clamping plates and the feeding ring form a movable clamping platform that can engage or disengage with the boss.

[0012] Furthermore, the movable clamping platform engages with the boss, the clamping plate abuts against the ball bearing, and the clamping plate can rotate relative to the boss via the ball bearing.

[0013] Furthermore, when the feeding ring and the fixed ring are an integral rotating structure, the fixed ring extends downward and the extended part is provided with a boss. The boss surface is provided with a ball. The top of the feeding ring is provided with a fixed locking platform that can engage with the boss. The fixed locking platform abuts against the ball.

[0014] Furthermore, the feeding ring is provided with a guide cylinder inside, the guide cylinder is connected to the bottom of the inner film bag, and the guide cylinder is detachably connected to the feeding ring.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0033] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0034] like Figures 1 to 11 As shown, this utility model provides a ton bag for easy unloading, including a bag body, a fixing ring, a feeding ring and a locking pin;

[0035] The ton bag body consists of an outer bag 11 and an inner membrane bag 12. The inner membrane bag 12 is fixedly installed inside the outer bag 11. There are four hanging rings 5 ​​at the top corners of the outer bag 11. Both the outer bag 11 and the inner membrane bag 12 have discharge ports 13 at their bottoms. The bottom of the outer bag 11 has a fixing ring 14 with a first channel 21. The bottom of the inner membrane bag 12 has a discharge ring 3 with a second discharge channel. The discharge ring 3 is rotatably connected to the fixing ring 14 and is located below the fixing ring 14. The discharge ring 3 and the fixing ring 14 are either an integral structure or a detachable structure. The discharge ring 3 has a locking pin 4 that can abut against the circumference of the fixing ring 14. The first channel is used to allow the inner membrane bag to pass through the bottom of the outer bag. The second channel is connected to the discharge port of the inner membrane bag. The discharge port of the inner membrane bag is connected to the inside of the second channel, which facilitates discharge and provides support to the bottom of the discharge port, making the discharge smoother.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 10 and Figure 11 As shown in the specific embodiment 1; when the feeding ring 3 and the fixing ring 14 are detachably connected, the fixing ring 14 extends downward and has a boss 22 at the bottom. An annular groove is provided on the upper surface of the boss 22, and a ball bearing 23 is provided in the groove. Symmetrical through holes are provided on both sides of the feeding ring 3. Elastic members 321 that can be stretched to both sides are installed on the through holes. The elastic members 321 are two sleeved columns, and a tension spring is provided in the column. Arc-shaped clamping plates 322 are provided on both sides of the elastic members 321. The clamping plates 322 are in contact with the circumference of the feeding ring 3. The clamping plate 322 is partially higher than the feeding ring 3. A transverse clamping plate extending inward is provided on the top of the clamping plate 322. The transverse clamping plate 322 is preferably arc-shaped. A movable clamping platform 323 is formed between the transverse clamping plate and the feeding ring 3. The movable clamping platform 323 is engaged on the boss 22. The transverse clamping plate is located above the ball bearing 23 and abuts against the ball bearing 23.

[0037] In the specific unloading method of Implementation 1, the clamping plates 322 are pulled to both sides. Since the clamping plates 322 are connected to the elastic element 321, they can be pulled to both sides to move the clamping plates 322 away from the boss 22 and detach them from the boss 22. At this time, the unloading ring 3 can be lowered, and the bottom plate of the inner film bag 12 connected to the unloading ring 3 can be pulled out of the outer bag 11. Rotate the unloading ring 3 to open the bottom of the inner film bag 12, that is, open the discharge port 13, so that the powder can be unloaded from the inner film bag 12. When it is necessary to close the discharge port 13, the clamping plates 322 are opened to both sides again, and the clamping plates 322 are clamped onto the boss 22 again. The movable clamping table 323 is engaged on the boss 22, and the clamping plates 322 clamp. After reaching the boss 22, rotate the feeding ring 3. The rotation of the feeding ring 3 causes the bottom of the inner film bag 12 to rotate and knot, thereby closing the discharge port 13. At the same time, rotate the locking pin 4 to fix the feeding ring 3 to the fixing ring 14, restricting the rotation of the feeding ring 3. This solves the problem that existing ton bags require untying the rope binding the discharge port 13 to open the discharge port 13 and retightening the rope to close the discharge port 13. Embodiment 1 of this utility model realizes that by rotating the feeding ring 3 to disengage from the fixing ring 14, the discharge port 13 can be opened, and the discharge port 13 can be closed by rotating the feeding ring 3. This is more efficient than slowly untying and retying the rope, making the unloading of ton bags more convenient.

[0038] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown in Embodiment 2; when the feeding ring 3 and the fixed ring 14 are an integral rotating structure, the fixed ring 14 extends downward and has a boss 22 at the bottom. A ball bearing 23 is provided on the upper surface of the boss 22. The structure of the fixed ring 14 is the same as in Embodiment 1 and will not be described further. The feeding ring 3 in Embodiment 2 differs from the feeding ring 3 in Embodiment 1. Specifically, the top of the feeding ring 3 has a fixed locking platform 331. The fixed locking platform 331 and the feeding ring 3 are integrally cast. An annular groove exists between the fixed locking platform 331 and the feeding ring 3. The annular groove can engage with the boss 22, thus connecting the feeding ring 3 and the fixed ring 14. The inner top surface of the fixed locking platform 331 of the feeding ring 3 abuts against the ball bearing 23. (Specific Embodiment 2) The feeding ring 3 is also equipped with a guide cylinder 332 inside, which is connected to the bottom of the inner film bag 12. A support plate 333 is provided at the bottom of the feeding ring 3. The support plate has a support groove 334. A notch 335 is provided on one side of the support groove 334. The top of the notch 335 is higher than the bottom of the support groove 334. A support column 336 is provided on the circumference of the guide cylinder 332. The support column 336 can be put into the support groove 334. The top of the notch 335 is higher than the bottom of the support groove 334. When the support column 336 is placed in the support groove 334, it can effectively prevent the support column 336 from sliding out of the support groove 334. At the same time, one end of the notch 335 can push the guide cylinder 332 to rotate synchronously when the feeding ring 3 is rotated.

[0039] In the specific feeding method of Example 2, the guide cylinder 332 is lifted upwards so that the support column 336 is higher than the notch 335, and the guide cylinder 332 is rotated to disengage the support column 336 from the support groove 334. After disengagement, the guide cylinder 332 can be stretched downwards, causing the bottom of the inner film bag 12 to be pulled out of the outer bag 11. The guide cylinder 332 is then rotated to open the bottom of the inner film bag 12, thus opening the discharge port 13, allowing the powder to be discharged from the inner film bag 12. When it is necessary to close the discharge port 13, the guide cylinder 332 is lifted, allowing the support column 336 to be reinserted. The material is fed into the support groove 334, and the feeding ring 3 is rotated, causing the feeding ring 3 to drive the guide cylinder 332 to rotate, so that the bottom of the inner film bag 12 is knotted, thereby closing the discharge port 13. This solves the problem that existing ton bags require untying the rope binding the discharge port 13 to open the discharge port 13 and re-tightening the rope to close the discharge port 13. By rotating the feeding ring 3 to disengage from the fixing ring 14, the discharge port 13 can be opened, and by rotating the feeding ring 3, the discharge port 13 can be closed. This is more efficient than slowly untying and re-tying the rope, making the unloading of ton bags more convenient.

[0040] A fixing pin is set on the feeding ring 3, and the locking pin 4 is a bolt. The side of the fixing pin that abuts against the fixing ring 14 is provided with an anti-slip pad. A threaded hole matching the locking pin 4 is opened on the feeding ring 3, and the fixing pin is fixedly connected to the threaded hole. Specifically, when the feeding ring 3 needs to rotate, the locking pin 4 is rotated counterclockwise to move one end of the anti-slip pad of the locking pin 4 away from the fixing ring 14, thereby realizing the rotation of the feeding ring 3. When it is necessary to lock the feeding ring 3, the locking pin 4 is rotated clockwise to make one end of the anti-slip pad abut against the fixing ring 14, thus completing the relative fixation between the feeding ring 3 and the fixing ring 14. The structure of the locking pin 4 installing the anti-slip pad is a mature existing technology, and this utility model is not illustrated in the accompanying drawings.

[0041] The outer side of the outer bag 11 is provided with lifting rings 5, which are arranged in pairs facing each other. The lifting rings 5 ​​can be used by crane to lift the ton bag, which facilitates the transfer and transportation of the ton bag.

[0042] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
