Description

Technical Field

[0001] The present invention belongs to the technical field of ton bag discharging, and in particular relates to a ton bag discharging module and a discharging system. Background Art

[0002] Ton bag (also known as ton bag, container bag, etc.) is a flexible transport packaging container, commonly used for packaging and transporting bulk granular and powdered materials. It has the characteristics of large volume, light weight, and easy loading and unloading. At the same time, it has a simple structure, light weight, can be folded, and takes up little space when transported back empty, and its application is becoming increasingly widespread.

[0003] Ton bags come in two basic forms: reusable and disposable. Disposable bags require the bag itself to be broken during discharge. Reusable bags have a flexible discharge port that is normally folded and tied with string to prevent leakage. During discharge, the string is released, allowing the material to fall out of the discharge port by gravity. Reusable bags are preferred for environmental protection and resource conservation. However, current reusable bags have the following issues: During discharge, the string must be manually released to loosen the flexible discharge port at the bottom of the bag. After discharge, the string must be manually tied to prevent residual material from leaking and contaminating the environment. This entire process requires manual intervention and is cumbersome, hindering the automation of material transfer. Furthermore, discharge generates dust that pollutes the surrounding environment, and the dust from corrosive materials can damage nearby machinery and equipment. Summary of the Invention

Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] Depend on Figure 1 and Figure 2 As shown together, the basic embodiment of the present invention showing the main concept discloses a ton bag discharge module; including a ton bag discharge valve device 1 and a material receiving device 2; the ton bag discharge valve device 1 includes a discharge valve base 11, a dial 12 rotatably connected to the discharge valve base 11, and a plurality of flower plates 13 arranged between the discharge valve base 11 and the dial 12; one end of the flower plate 13 is rotatably connected to the discharge valve base 11 and one of the dials 12, and the other end is rotatably connected to the discharge valve base 11 and the dial 12. Another radial sliding connection; the discharge valve base 11 is provided with a first central through hole 111 for the flexible discharge port of the ton bag to pass through, and multiple flower plates 13 together surround an intermediate adjustment port 131 for the flexible discharge port of the ton bag to pass through, and the dial 12 is provided with a second central through hole 121 for the flexible discharge port of the ton bag to pass through; when the dial 12 is turned, the flower plates 13 (rotate around their respective rotation centers) are opened or closed, and when the flower plates 13 are opened, the intermediate adjustment port 131 becomes larger to release the flexible discharge port of the ton bag (see Figure 4 ); When the flower plate 13 is closed, the middle adjustment port becomes smaller and tightens the flexible discharge port of the ton bag (see Figure 3); the material receiving device 2 includes a material receiving base 21, which is provided with a material receiving port 22, in which a mounting seat 24 is rotatably mounted by means of a bearing 23, and the mounting seat 24 has an inner cavity 241 adapted to the dial 12; the material receiving base 21 is provided with a driving mechanism 25 for driving the mounting seat 24 to rotate; when the dial 12 is installed in place on the inner cavity 241, the dial 12 and the mounting seat 24 rotate synchronously.

[0041] During use, the discharge valve base 11 is fixed to the body of the ton bag 3, and the flexible discharge port of the ton bag is sequentially passed through the first central through hole 111, the intermediate adjustment port 131, and the second central through hole 121. Before discharging, the intermediate adjustment port 131 tightens the flexible discharge port of the ton bag; when docking with the material receiving device 2 for discharging, the driving mechanism 25 drives the mounting base 24 to rotate, thereby driving the driving dial 12 to rotate synchronously, so that the intermediate adjustment port 131 becomes larger and the flexible discharge port of the ton bag is loosened. Without manual intervention, the flexible discharge port of the ton bag can be automatically loosened or tightened, which is simple to operate and facilitates the automation of the material transfer process. In addition, the dust stirred up during the discharge process cannot overflow, achieving dust-free discharge.

[0042] In a specific embodiment, Figure 3 、 Figure 6 As shown together, a plurality of rotary pin holes 112 are circumferentially evenly spaced at the bottom of the discharge valve base 11 around the first central through hole 111, and a plurality of radially extending waist-shaped guide grooves 122 (i.e., long strip holes) are circumferentially evenly spaced at the bottom of the dial 12 around the second central through hole 121; the number of the rotary pin holes 112 and the waist-shaped guide grooves 122 is consistent with the number of the flower plates 13; a rotary pin 132 rotatably connected to the rotary pin hole 112 is provided above one end of the flower plate 13, and a dial pin 133 slidably connected to the corresponding waist-shaped guide groove 122 is provided below the other end.

[0043] When the pin 133 is located at one end of the waist-shaped guide groove 122 near the second central through hole 121, the flower plates 13 are closed and the plurality of flower plates 13 are in a staggered state (see FIG. Figure 3 When the pin 133 is located at one end of the waist-shaped guide groove 122 away from the second center through hole 121, the flower plate 13 is opened, and the three flower plates 13 are separated from each other (see Figure 4 Preferably, the center of one end of the waist-shaped guide groove 122 adjacent to the second central through hole 121 and the center of the swivel pin hole 112 are located on two coaxial circles with the same radius.

[0044] Preferably, there are three flower plates 13, which can not only realize the adjustment of the middle adjustment port 131 to be larger or smaller, but also save costs and simplify installation. Further preferably, the flower plates 13 are arc-shaped flower plates, which are installed at an angle, and the sliding connection end of the flower plate 13 is inclined relative to the rotating connection end toward the dial 12; when the flower plates 13 are closed, the three flower plates 13 are in a staggered state (by Figure 3 As shown, it can also be understood as a weaving state), that is, the sliding connection end of the first flower plate 13 is located on the side of the rotating connection end of the second flower plate 13 facing the dial 12, the sliding connection end of the second flower plate 13 is located on the side of the rotating connection end of the third flower plate 13 facing the dial 12, and the sliding connection end of the third flower plate 13 is located on the side of the rotating connection end of the first flower plate 13 facing the dial 12; in this way, the flower plate 13 can be prevented from interfering with the rotating pin 132 during rotation. In order to ensure the smoothness of the opening and closing of the flower plate 13, the sliding connection end and the rotating connection end of the flower plate 13 can be provided with guide slopes that are convenient for interlacing with each other. According to the arrangement of the three flower plates 13 mentioned above, the arrangement of four or more flower plates 13 can be easily derived. Therefore, the present invention does not limit the number of flower plates 13, as long as multiple flower plates 13 can enclose an intermediate adjustment port 131, and the intermediate adjustment port 131 can be enlarged or reduced when the flower plate 13 is rotated to open or close.

[0045] In another specific embodiment (not shown in the figure), the waist-shaped guide groove 122 is set at the bottom of the discharge valve base 11, and the rotary pin hole 112 is set at the bottom of the dial 12; in this case, the setting positions of the rotary pin 132 and the dial pin 133 on the flower plate 13 need to be adjusted accordingly. At the same time, the inclination direction of the flower plate 13 and the vertical staggered relationship between the multiple flower plates 13 also need to be adjusted accordingly. From the perspective of a person skilled in the art, it is easy to adjust the position of the flower plate 13 according to the following formula: Figure 2 The specific structure of this embodiment is imagined and will not be described in detail here.

[0046] In another specific embodiment, the discharge valve base 11 includes a cylindrical body 113, and a first hook structure 114 is provided on the outer peripheral wall of the bottom end of the cylindrical body 113; a second hook structure 123 is provided on the inner peripheral wall of the top end of the dial 12; the first hook structure 114 is engaged with the second hook structure 123 (see Figure 6 ) to achieve rotatable installation between the discharge valve base 11 and the dial 12. In addition, by reasonably designing the cone angles of the first hook structure 114 and the second hook structure 123, self-locking can be achieved before discharge to prevent the dial 12 from rotating without driving force; the principle is as follows: Ton bag 3 (see Figure 10 During the lifting process, the panel 13 is subjected to pressure from the material within the tote bag 3 and transmits this pressure to the dial 12, causing the second hook structure 123 of the dial 12 to press against the first hook structure 114 on the discharge valve base 11. The greater the pressure, the greater the friction, which in turn enables the dial 12 to self-lock, preventing the panel 13 from pushing back under the weight of the material and causing malfunction of the dial 12. In short, the installation and locking of the dial 12 and the discharge valve base 11 are achieved through the elastic deformation of the first hook structure 114 and the second hook structure 123, thereby simplifying the structure.

[0047] Optionally, the bottom end of the first hook structure 114 is provided with a first guide cone 116, and the top end of the second hook structure 123 is provided with a second guide cone 124 adapted to the first guide cone 116. Such an arrangement can increase the guide performance and facilitate the installation of the dial 12 and the discharge valve base 11.

[0048] In some other embodiments, although the first hook structure 114 and the second hook structure 123 are not adopted, in order to prevent the dial 12 from malfunctioning, a rotation damping member is added between the relatively rotating dial 12 and the discharge valve base 11; to ensure that the dial 12 can only rotate when an external force drives it; to ensure the reliability and safety of the discharge valve device 1 for ton bags.

[0049] Optionally, a limiting edge 115 is provided around the outer circumference of the top end of the cylindrical body 113. The limiting edge 115 and the cylindrical body 113 are integrally injection-molded. The limiting edge 115 is designed to be relatively thin, allowing it to be sewn directly to the bottom of the ton bag 3. Alternatively, the discharge valve base 11 can be connected to the ton bag 3 via other methods (such as adhesive bonding or hot-melt welding) as needed, which will not be discussed here.

[0050] In a preferred embodiment, the first central through hole 111 and the second central through hole 121 have the same diameter and are concentric.

[0051] Among them, Figure 7 As shown, the material receiving base 21 is also equipped with a bearing cap 28 for axially limiting the bearing 23 and the mounting seat 24. Furthermore, preferably, an anti-rotation structure is provided between the discharge valve base 11 and the bearing cap 28 or the material receiving base 21. This anti-rotation structure can be a pin-hole pin-shaft structure, a magnetic structure, a plug-in structure, or a radially extending concave-convex corrugated structure. This prevents the ton bag 3 and the discharge valve base 11 from rotating synchronously with the dial 12 when the ton bag 3 is nearly empty, ensuring operational stability after the ton bag 3 is emptied (i.e., ensuring the tightening effect of the ton bag's flexible outlet).

[0052] In one specific embodiment, the outer circumference of the dial 12 is an outer conical surface that contracts inward from top to bottom; the inner circumferential wall of the inner cavity 241 is an inner conical surface that matches the outer conical surface; and the friction between the outer and inner conical surfaces enables synchronous rotation. Thus, after the dial 12 is installed on the mounting seat 24, the mounting seat 24 provides a certain lifting effect on the dial 12, which can reduce or even eliminate the compressive force between the second hook structure 123 on the dial 12 and the first hook structure 114 on the discharge valve base 11, thereby releasing the self-locking function of the dial 12. This lifting effect also increases the pressure between the outer and inner conical surfaces, increasing the friction between the contacting conical surfaces between the two, allowing the mounting seat 24 to more reliably drive the dial 12 to rotate.

[0053] In addition, the surface roughness of the outer and inner conical surfaces can be increased (e.g., by adding a pattern) to increase the friction between the outer and inner conical surfaces, thereby improving the reliability of the synchronous rotation connection. A synchronous rotation connection structure can also be provided between the outer and inner conical surfaces; the synchronous rotation connection structure includes a groove and a protrusion, with one of the grooves and protrusions provided on the outer conical surface and the other of the grooves and protrusions provided on the inner conical surface. Furthermore, preferably, the bottom end of the outer conical surface and the top end of the inner conical surface are chamfered to enhance guidance and facilitate docking of the dial 12 and the mounting seat 24.

[0054] In some embodiments, a ring gear 26 is provided on the outer peripheral wall of the mounting seat 24 (preferably, a limiting step is formed on the outer peripheral wall of the mounting seat 24, and the ring gear 26 is provided on the limiting step), and the driving mechanism 25 includes a linear reciprocating drive module and a rack structure provided on the power part of the linear reciprocating drive module, and the rack structure is engaged with the ring gear 26; the linear motion rack structure drives the ring gear 26 and the mounting seat 24 to rotate. Figure 8 In the illustrated embodiment, a ring gear 26 is provided around the outer circumference of the mounting base 24. The drive mechanism 25 comprises a support structure 251 mounted on the material receiving base 21, a rotary drive module 252 mounted on the support structure 251, and a drive gear 253 mounted at the output end of the rotary drive module 252 and meshing with the ring gear 26. The rotary drive module 252 transmits rotational power to the drive gear 253, which in turn drives the ring gear 26 and the mounting base 24 to rotate. This arrangement simplifies the structure and saves installation space. Preferably, the rotary drive module 252 includes a motor 2521 and a reducer 2522.

[0055] In another specific embodiment, the support structure 251 includes an end cap 2511 mounted on the mounting opening of the material receiving base 21 and a support frame 2512 (including a bracket and a mounting plate arranged from top to bottom) disposed at the bottom of the end cap 2511. The rotary drive module 252 is mounted on the support frame 2512. A plurality of arc-shaped adjustment holes 2513 are circumferentially spaced apart on the edge of the top end of the end cap 2511. Threaded connectors 2514 pass through the arc-shaped adjustment holes 2513 and are fixedly connected to the material receiving base 21. A predetermined eccentricity C exists between the central axis of the end cap 2511 and the rotational axis of the drive gear 253. Before being fixed to the material receiving base 21, the end cap 2511 is rotatable, and the threaded connector 2514 can slide relative to the arc-shaped adjustment holes 2513. By rotating the end cap 2511, the center distance between the drive gear 253 and the ring gear 26 can be adjusted to achieve a suitable meshing state, thereby ensuring the effective transmission of rotational power.

[0056] In another specific embodiment, Figure 7 and Figure 9As shown, the material receiving device 2 also includes a protective cover 27. The protective cover 27 comprises an annular base plate 271, an inner ring guard plate 272, and an outer ring guard plate 273. The inner ring guard plate 272 has a first annular mounting portion 274 extending radially inward at its top end, while the outer ring guard plate 273 has a second annular mounting portion 275 extending radially outward at its top end. The mounting base 24 has an annular retaining groove 242 at its bottom end. The first annular mounting portion 274 engages with and rotatably engages with the annular retaining groove 242. The second annular mounting portion 275 is fixedly connected to the material receiving base 21. The bearing 23, the ring gear 26, and the drive mechanism 25 are located within the annular protective space defined by the protective cover 27. This prevents material from entering the bearing 23, the ring gear 26, and the drive mechanism 25, and also prevents lubricant from the bearing 23 from entering the material. The protective cover 27 can be made of plastic.

[0057] The embodiment of the present invention also discloses a discharge system, which comprises Figure 10 As shown, the ton bag 3 and the storage tank body 4 are comprised of a main body and a flexible ton bag discharge port. The ton bag 3 also includes a ton bag discharge module as disclosed in any of the above embodiments. The discharge valve base 11 is mounted on the bottom of the main body, and the material receiving device 2 is mounted on the inlet of the storage tank body 4. Preferably, the inlet is stepped, with a second annular mounting portion 275 sandwiched between the material receiving base 21 and the stepped surface of the inlet. This reduces the number of screws required and simplifies the installation process.

[0058] Based on the above structure, the following is a brief description of the ton bag discharge process:

[0059] The crane hoists the ton bag 3, equipped with the ton bag discharge valve device 1, above the storage tank 4, to which the material receiving device 2 is installed. The crane is controlled to align the dial 12 in the ton bag discharge valve device 1 with the inner cavity 241 of the mounting seat 24. The crane then slowly lowers the dial 12 into the mounting seat 24 to complete the docking. When the sensor detects that the dial 12 and the mounting seat 24 are docked, the controller controls the rotary drive module 252 in the drive mechanism 25 to rotate forward, driving the gear 253 to rotate, driving the ring gear 26 and the mounting seat 24 to rotate, and then driving the dial 12 to rotate. When the dial 12 rotates, the waist-shaped guide groove 122 on it cooperates with the dial pin 133 to make the flower plate 13 rotate around its rotating pin 132, the flower plate 13 opens, the middle adjustment port 131 becomes larger, and the flexible discharge port of the ton bag is loosened. The material contained in the ton bag 3 leaks into the storage tank body 4 by gravity; during the ton bag discharge process, due to the action of gravity, the ton bag discharge valve device 1 and the material receiving device 2 fit tightly together without any gaps, and the dust stirred up during the discharge process cannot overflow, achieving dust-free discharge. After the discharge is completed, when the controller controls the rotary drive module 252 in the drive mechanism 25 to rotate in the opposite direction, the flower plate 13 is closed, the middle adjustment port 131 becomes smaller, and the flexible discharge port of the ton bag is tightened. Even if some residual material remains in the ton bag 3, it will not leak out, avoiding material waste and environmental pollution.

[0060] The various embodiments in this specification are described in a progressive or parallel manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referenced to each other.

[0061] In summary, the present invention can automatically loosen or tighten the flexible discharge port of the ton bag without human intervention, is simple to operate, and facilitates the automation of the material transfer process; and can effectively avoid dust overflow during the discharge process, achieving dust-free discharge.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
