Description

Technical Field

[0001] The utility model belongs to the technical field of bag breaking of bagged powder, and in particular relates to a ton bag breaking device. Background Art

[0002] Ton bags, also known as container bags, are a type of soft packaging container, generally made of polyester fibers such as polypropylene and polyethylene. They are moisture-proof, dust-proof, firm and safe, and have sufficient structural strength. Due to their large packaging capacity, ton bags are very convenient for loading, unloading, transporting and use, which significantly improves loading and unloading efficiency. In recent years, the use of ton bag packaging technology for powder materials has developed rapidly.

[0003] Well cementing operations require powder materials such as cement, waterproofing agents, and drag reducers. When these powder materials are used in large quantities, they are usually delivered to the mixing site in tons of packaging. The bag breaking devices commonly seen at the work site are mostly formed by cutting steel plates, which have a slow bag breaking speed and poor bag breaking effect, resulting in secondary or multiple bag openings, increasing the workflow, and easily causing a large amount of dust to overflow, causing a large dust problem at the work site and endangering the health of on-site operators.

[0004] As an improvement, a Chinese utility model patent with authorization announcement number CN202389656U and authorization announcement date August 22, 2012 discloses a passive ton bag automatic bag opener, including a feeding platform, the feeding platform has an opening which is gradually concave from the outside to the inside, a cross-shaped tool holder is fixed at the opening, two triangular blades with the tips facing upwards in a cross are fixed to the cross-shaped tool holder, and a feeding bucket is fixed to the lower end of the opening.

[0005] However, the blade is fixed to the knife holder and then fixed as a whole to the unloading platform. When it needs to be moved, the bag opener needs to be moved as a whole, which increases the working intensity. At the same time, when the blade is partially damaged, the device needs to be replaced as a whole, which increases the working cost. At the same time, after the ton bag is pierced by the tip of the triangular blade, it gradually falls by its own weight and is further cut by the blade. When the ton bag gradually covers the opening of the unloading platform, the part of the blade at the bottom can no longer play a cutting role. When dealing with the blockage of powder in the opening, this part of the blade poses a risk of injuring the operator. In addition, the bottom of the blade occupies a certain opening space, which reduces the capacity of the opening to accommodate powder to a certain extent. If the powder becomes damp and agglomerated, it will directly enter the mixing tank through the opening space separated by the cross-shaped knife holder and the blade, and the agglomerated powder will affect subsequent operations. Utility Model Content

[0006] The purpose of the utility model is to provide a ton bag breaking device to solve the problem in the prior art that the blade is fixed to the unloading platform via a blade holder and needs to be replaced as a whole when the blade is partially damaged, which increases the operating cost, and the need to carry the whole bag when moving, which increases the operating intensity.

[0009] Furthermore, the base includes a support plate for supporting the edge of the feed port of the mixing tank and an insertion section connected to the support plate and used to cooperate with the feed port. The feed discharge channel runs through the support plate and the insertion section, and the feed discharge channel is a conical channel that is larger at the top and smaller at the bottom.

[0010] Furthermore, each of the supporting legs is seated in the tapered channel, and the diameter of the circle where the contact point between each of the supporting legs and the tapered channel is located is greater than the diameter of the discharge port of the tapered channel.

[0021] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0022] The utility model provides a ton bag breaking device, which forms a puncturing structure for puncturing the ton bag through the upper overlapping parts of each blade, and the puncturing structure punctures the ton bag during the falling process of the ton bag, thereby achieving the breaking of the ton bag; the blade holder is seated in an inverted cone-shaped feeding channel through the supporting feet at the lower parts of the blade wings, so that the blade holder and the supporting seat can be easily separated, and the blade holder or the supporting seat can be moved separately as needed, which effectively reduces the working intensity, and at the same time, the puncturing structure can be replaced by replacing the blade holder, which effectively reduces the working cost.

[0023] Embodiment of the ton bag breaking device in the utility model:

[0024] like Figure 1 As shown, this embodiment provides a ton bag breaking device, including a base 2 with a feeding channel and a knife holder, the knife holder includes at least three evenly distributed blade wings 1, the upper overlapping parts of each blade wing 1 constitute a puncturing structure for puncturing the ton bag, and the lower part of each blade wing 1 is a support foot seated in the feeding channel 23.

[0025] Specifically, the base 2 includes an insertion section 22 for matching with the feed port of the mixing tank and a support plate 21 connected to the insertion section 22 and used to support the edge of the feed port of the mixing tank; a material discharge channel 23 is provided inside the base 2 and passes through the support plate 21 and the insertion section 22. In this embodiment, the support plate 21 and the insertion section 22 are separately provided and connected as a whole by welding; of course, the support plate 21 and the insertion section 22 can be integrally formed.

[0026] The knife holder includes four evenly distributed blade wings 1, each blade wing 1 has a blade tip 13 at one end away from the material discharge channel 23, and multiple blade tips 13 converge and connect to form a "cross"-shaped conical tip, which forms a puncturing structure for puncturing the ton bag; the end of the blade wing 1 that contacts the inner wall of the material discharge channel 23 constitutes a support foot of the blade wing 1, and each support foot is respectively seated in the material discharge channel 23. As other embodiments, the number of blade wings 1 can be set to three or other suitable numbers, and the specific number of blade wings 1 can be reasonably selected according to needs, so as to facilitate bag breaking and ensure the falling of powder.

[0027] The conical tip formed by the blade tip 13 facilitates puncturing the ton bag and can realize radial positioning of the ton bag; when in use, the conical tip first contacts the ton bag, and the bottom of the bag body is punctured by the conical tip, thereby realizing breaking the ton bag; the tool holder is placed in the unloading channel 23 in a non-fixed connection manner, so that the tool holder and the base 2 are separated, and the movement of the tool holder or the base 2 can be facilitated as needed, thereby effectively reducing the operating intensity; when the puncturing structure is damaged, the puncturing structure can be replaced only by replacing the tool holder, effectively reducing the overall replacement operating cost.

[0028] In this embodiment, the feeding channel 23 is a tapered channel that is larger at the top and smaller at the bottom, that is, the parts of the feeding channel 23 in the insertion section 22 and the support plate 21 are tapered channels that are larger at the top and smaller at the bottom. Of course, in other embodiments, the feeding channel in the support plate 21 can be a through-path channel, and the insertion section 22 includes a through-path channel portion that is connected to the through-path channel of the support plate 21 and a tapered channel portion for supporting the knife holder; or, the feeding channel 23 is a stepped channel. The support plate 21 provided can stably support the base 2 on the edge of the feed port of the mixing tank, and the powder after the bag is broken can be directly input into the mixing tank through the insertion section 22 provided; the tapered channel that is larger at the top and smaller at the bottom facilitates the blade 1 to sit on the inner wall of the feeding channel 23. It should be understood that the cross-section of the inverted tapered feeding channel 23 can be circular or square, or other suitable shapes, specifically for the convenience of processing and feeding to make a reasonable choice, which is not limited in this embodiment.

[0029] In order to ensure that the tool holder can effectively sit in the insertion section 22 of the feeding channel 23 through the support feet of the blade wing 1, in this embodiment, the diameter of the circle where the contact points of each support foot and the feeding channel 23 are located is larger than the discharge port diameter of the insertion section 22, so that the support feet of the blade wing 1 can be formed with a limiting support through the inner wall of the tapered channel of the insertion section 22, thereby effectively ensuring that the tool holder can effectively contact the inner wall of the feeding channel 23, making it convenient to seat the tool holder in the feeding channel 23.

[0030] It should be noted that in order to ensure the stability of the knife holder seated in the material discharge channel 23, the center of gravity of the knife holder needs to fall on the central axis of the material discharge channel 23 after being placed. Specifically, the central axis of the piercing structure coincides with the central axis of the material discharge channel 23. This ensures the stability of the knife holder after it is seated in the material discharge channel 23, and avoids the knife holder from tilting during use and affecting the safety of use.

[0031] In order to adapt to different mixing tank feed ports, in this embodiment, the outer circumference of the insertion section 22 is a conical structure. The outer circumference of the conical structure can adapt to mixing tank feed ports of different specifications, thereby increasing the applicability of the base 2. Of course, in other embodiments, the outer circumference of the insertion section 22 can be a cylindrical structure.

[0032] In this embodiment, the lower part of the blade 1 has a hollow structure 122. Specifically, the blade 1 can be in the shape of an obtuse triangle, one of the short sides of each blade 1 is connected to form a piercing structure at the blade tip, and the hollow structure 122 is formed below the other short side of each blade 1 after being connected.

[0033] As a further embodiment, the blade 1 includes a triangular section 11 and a trapezoidal section 12 connected to the triangular section 11, and a hollow structure 122 for communicating with the feeding channel 23 is provided at the lower part of the trapezoidal section 12, wherein the trapezoidal section 12 forms a foot for supporting the blade holder; the tip of the triangular section 11 away from the feeding channel 23 forms a blade tip 13. The triangular section 11 effectively ensures the stability of the structure of the blade 1, and the trapezoidal section 12 ensures the structural strength of the blade 1 after the hollow structure 122 is provided; the hollow structure 122 is provided, so that the trapezoidal section 12 reduces the space occupied by the feeding channel 23, and increases the powder holding capacity of the feeding channel 23. It should be understood that the size of the hollow structure 122 can be appropriately adjusted without affecting the strength of the blade 1.

[0034] In order to improve the bag breaking speed and effect, as a further implementation method, a blade 3 is provided on the hypotenuse 111 of the triangular segment 11. Specifically, the blade is connected to the hypotenuse 111 of the blade 1 by welding, riveting, bolting or other suitable connection methods. Since the hypotenuse 111 of the triangular segment 11 of the blade 1 forms a certain angle with respect to the horizontal plane, the blade 3 provided thereon is also in an inclined state, which can effectively increase the contact surface between the ton bag and the blade 3. At the same time, the inclination angle of the blade 3 can make it easier to cut the ton bag. When in use, the puncture structure formed by the blade tip 13 first contacts the ton bag, and the bag body of the ton bag is punctured, and then the blade 3 further cuts along the puncture point during the falling process of the ton bag to form a radial rupture, which speeds up the ton bag breaking speed.

[0035] In this embodiment, at least two fixing holes are provided on the hypotenuse 111 of the triangular segment 11, and the blade 3 is connected to the fixing holes by bolts, so as to realize the detachable connection between the blade 3 and the blade wing 1. The detachable connection mode facilitates the separate replacement of the blade 3 after it is damaged, further reducing the use cost.

[0036] In this embodiment, the length of the blade 3 is not greater than the length of the bevel 111, so that the blade 3 can avoid blocking the tip 13 of the blade wing 1 by bolt connection; at the same time, the blade 3 is not provided on a portion of the bevel 111, thereby avoiding the risk of injury by the protruding blade 3 during use. Of course, in other embodiments, the length of the blade 3 can be not less than the bevel 111, so that the mutually converged portions of the blade 3 form a piercing structure. It should be understood that the specific size of the blade can be reasonably selected according to the size of the ton bag and the actual needs of the operation, and this is not limited in this embodiment.

[0037] In order to further improve the bag breaking effect, in this embodiment, both sides of the bevel 111 can be connected with a blade 3 by bolts. Of course, in other embodiments, the blade 3 can be connected only on one side of the bevel 111; or the part where the blade is connected to the bevel is a U-shaped groove, and the blade is connected by the U-shaped groove and the bevel 111. It should be understood that the specific number of blades 3 can be increased or decreased according to the actual bag breaking operation requirements; accordingly, the setting position of the blade 3 can also be adjusted according to the actual operation requirements.

[0038] In order to enhance the stability of the blade 1 when it cooperates with the material discharge channel 23, in this embodiment, a support ring (not shown in the figure) is fixedly provided on the support foot. Specifically, the annular support ring is fixedly connected to the inner side of the bottom end of the trapezoidal section 12 of the blade 1 by welding; of course, the support ring can also be welded to the outer side of the trapezoidal section 12, and the support ring is in contact with the inner wall surface of the material discharge channel 23. The support ring is provided to effectively ensure the stability of the lower part of the blade 1, and improve the safety during the bag breaking operation.

[0039] As other embodiments, in order to achieve better contact between the blade wing 1 and the inner wall of the feed channel 23, so that the tool holder can be stably placed in the base 2, in this embodiment, a conical surface structure for cooperating with the feed channel is provided on the support foot; specifically, the side of the trapezoidal segment 12 in contact with the feed channel 23 has a conical structural surface adapted to the conical channel of the insertion section 22 of the feed channel 23, thereby effectively increasing the contact area between the trapezoidal segment 12 and the feed channel 23, and improving the stability of the tool holder placed in the base 2.

[0040] In order to filter the powder, the tool holder also includes a filter screen 4 disposed at the bottom end of the trapezoidal segment 12. Specifically, the filter screen 4 is disposed on the support ring. The filter screen 4 is provided to effectively filter the powder, and can break up large pieces of powder that have become damp and agglomerated, while preventing debris or other foreign matter generated during the bag breaking process from falling into the mixing tank. In this embodiment, the size of the filter screen 4 can be set according to the size of the tool holder; the structure of the filter screen 4 can be a grid structure or a mesh structure; of course, a filter plate with sieve holes can also be used without affecting the removal of debris and the discharge of materials; it should be understood that the specific structural form and size of the filter screen 4 can be reasonably selected according to actual needs, and this is not limited in this embodiment.

[0041] In order to prevent the blade 3 from causing harm to the operator during transportation, in this embodiment, the blade 3 is provided with a protective cover (not shown in the figure), which may be a silicone cover or other existing technology, and will not be described in detail here.

[0042] As another embodiment, the blade is integrally arranged with the triangular section of the blade wing, that is, a cutting edge for cutting ton bags is formed on the hypotenuse of the triangular section; accordingly, the length of the cutting edge is smaller than the length of the hypotenuse.

[0043] As another embodiment, in order to facilitate the connection of the blade wings, the ends of the blade wings away from the feeding channel are connected to the same adapter, and a conical piercing structure is provided on the adapter.

[0044] When in use, the support plate 21 of the base 2 is placed on the feed port on the cementing mixing tank, the insertion section 22 of the base 2 is inserted into the feed port, and then the tool holder assembled with the blade 3 and the filter screen 4 is placed into the discharge channel 23 of the base 2 to form a ton bag breaking device; when performing the bag breaking operation, the ton bag is lifted by a crane or other lifting equipment, the ton bag is transferred to the top of the ton bag breaking device, and the ton bag is slowly lowered. Under the action of the ton bag's own weight, the conical tip and the blade 3 are used to cut the ton bag, and the powder enters the mixing tank through the discharge channel 23.
