Description

Technical Field

[0001] This invention relates to the field of material batching technology, specifically to a bag-breaking and feeding machine and batching system for agglomerated materials. Background Technology

[0002] Bulk materials are further categorized into powders, granules, and agglomerates. Within the industry, batching systems for powders and granules are relatively mature, with numerous manufacturers in the market. However, there are currently no fully automated, mature cases for unpacking and batching agglomerates. For bulk materials such as salt, alkali, calcium, and urea, which have relatively low hardness after agglomeration, semi-automatic crushing machines are used for pre-crushing. After pre-crushing, unpacking and batching are performed manually, by robots, or by other equipment. For materials like rosin and petroleum resin, which have high hardness after agglomeration, there are no relevant automated cases in the industry. Furthermore, due to the agglomeration characteristics of agglomerates, they cannot be stored in silos or stacks; they are typically stored in 20-25KG small bags, stacked and palletized. Therefore, for this type of agglomerate storage condition, a bag-breaking and feeding machine and batching system for agglomerate materials are provided for fully automated unpacking and batching. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a bag-breaking and feeding machine and a batching system for agglomerated materials.

[0004] The agglomerated material bag-breaking and feeding machine and batching system of the present invention includes: a gantry robot, wherein a stacking station and a batching and crushing device are provided below the work station of the gantry robot, and the batching and crushing device consists of a weighing belt conveyor, a pre-crusher, and a bag-breaking and feeding machine arranged in sequence; The pre-crusher includes a frame on which a load-bearing roller assembly is installed to connect with the conveyor face of the weighing belt conveyor. An automatically lifting pre-crusher is provided above the load-bearing roller assembly, and a crushing channel is formed between the pre-crusher and the load-bearing roller assembly. The bag-breaking and feeding machine includes a conveyor connected to the bearing roller assembly and a feeding hopper installed below the conveyor. Cutting blades with a spacing smaller than the width of the material bag are installed on both sides of the conveyor.

[0005] In some embodiments, the pre-crusher includes a mounting frame on which a crushing motor and a crushing roller are mounted, and the crushing motor is drivenly connected to the crushing roller. The pre-crusher also includes multiple lifting guide rods inserted into the mounting frame. Both ends of the lifting guide rods are mounted on the frame, and springs for applying pressure to the mounting frame are sleeved on the lifting guide rods.

[0006] In some embodiments, the crushing roller includes a rotating main shaft rotatably connected to a mounting frame, two mounting plates are mounted on the rotating main shaft, and a plurality of small crushing rollers are mounted between the two mounting plates. The plurality of small crushing rollers are arranged in a ring around the rotating main shaft as the central axis, and the length of the small crushing rollers is greater than the width of the packaging material.

[0007] In some embodiments, both sides of the starting end of the conveyor are provided with non-powered roller groups, the outer distance between the two non-powered roller groups is less than the width of the packaging bag, and the two cutting blades are located on the outer side of the two non-powered roller groups.

[0008] In some embodiments, the conveyor is equipped with striking plates on both sides near the end of the unpowered roller assembly. The width formed by the two striking plates is greater than the width of the material bag, and the rotation axis of the striking plates is perpendicular to the conveying direction plane of the conveyor. The far end of the striking plates when rotating is close to the end of the unpowered roller assembly.

[0009] In some embodiments, the two striking plates are arranged at a planar angle, and the angle is preferably 90 degrees.

[0010] In some embodiments, a packaging bag guiding mechanism is also included, which includes a limiting member installed between two striking plates and is obliquely upward toward the unpowered roller assembly.

[0011] In some embodiments, the packaging bag guiding mechanism further includes a guide member parallel to the conveyor conveying direction, and the guide member is connected to the bottom of the limiting member, and a waste channel for the packaging bag to pass through is provided between the guide member and the conveyor.

[0012] In some embodiments, the end of the guide is positioned downwards and extends out of the dispensing hopper.

[0013] In some embodiments, there are two sets of stacking stations and batching and crushing devices. The two sets of stacking stations are located at both ends of the gantry robot station. The two batching and crushing devices share a pre-crusher. The other two weighing belt conveyors are respectively set up adjacent to the pre-crusher. The two bag-breaking feeders are installed on the outside of the two adjacent pre-crushers. A bag collection area may be provided between the bag-breaking feeders and the stacking station.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a pre-crusher to crush packaging bags containing agglomerated material, thereby effectively achieving preliminary crushing of the agglomerated material. The weighing belt conveyor effectively records the material, facilitating subsequent batching. The bag-breaking and feeding machine can not only cut the packaging bags but also further crush and refine the material in the packaging bags, further optimizing the batching of agglomerated material.

[0015] 2. This invention uses a non-powered roller assembly to support the packaging bag, effectively preventing large pieces of material from falling directly after passing through the cutting edge. The striking plate, installed at the end of the non-powered roller assembly, effectively strikes the packaging bag that has detached from the assembly, further crushing the material inside. The impact causes the material to move inside the bag, thus deforming and opening the bag opening. This effectively achieves bag breaking and material discharge while also crushing the material and preventing large clumps from directly entering the batching hopper. Attached Figure Description

They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this invention.

[0020] Example 1: Please see Figures 1-5 The agglomerated material bag breaking and feeding machine and batching system of the present invention includes: a gantry robot 1, a stacking station 2 and a batching and crushing device 3 below the station of the gantry robot 1, and the batching and crushing device 3 is composed of a pre-crusher 31 and a bag breaking and feeding machine 33 arranged in sequence. The pre-crusher 31 includes a frame 311, on which a bearing roller group 312 is installed that is in contact with the conveying surface of the weighing belt conveyor 32. The pre-crusher 31, which can be automatically lifted and lowered, is provided above the bearing roller group 312. A crushing channel 314 is formed between the pre-crusher 31 and the bearing roller group 312. The bag-breaking and feeding machine 33 includes a conveyor 331 that is connected to the bearing roller group 312, and a feeding hopper 332 installed below the conveyor 331. Cutting blades 333 with a spacing smaller than the width of the material bag are installed on both sides of the conveyor 331. The cutting blades 333 can be blades, saw blades, etc.

[0021] Both sides of the starting end of the conveyor 331 are equipped with unpowered roller groups 334. The distance between the outer sides of the two unpowered roller groups 334 is less than the width of the packaging bag, and the two cutting blades 333 are located on the outer side of the two unpowered roller groups 334.

[0022] The conveyor 331 is equipped with two striking plates 335 on both sides near the end of the unpowered roller assembly 334. The width formed by the two striking plates 335 is greater than the width of the material bag, and the rotation axis of the striking plates 335 is perpendicular to the conveying direction plane of the conveyor 331. The far end of the striking plates 335 when rotating is close to the end of the unpowered roller assembly 334.

[0023] It also includes a batching and crushing device 3 and a weighing belt conveyor 32; Working principle: The gantry robot 1 in the device starts up, thereby grabbing the packaging bag containing the material and placing it in the weighing belt conveyor 32. After being weighed by the weighing belt conveyor 32, it enters the crushing channel 314 of the pre-crusher 31. The pre-crusher 31 crushes the material in the packaging bag and conveys it to the conveyor 331 of the bag breaking and feeding machine 33. When the material is placed on the conveyor 331 of the bag breaking and feeding machine 33, the two sides of the packaging bag will be lifted and conveyed by the non-powered roller group 334 to pass through the cutting blade 333. When the packaging bag passes through the cutting blade 333, an opening will be made. Because the unpowered roller assembly 334 supports the packaging bag, the opening of the packaging bag will not open wider. In other words, the material inside the packaging bag will not fall directly in large areas, especially larger pieces of material will not fall from the unopened opening. When the packaging bag with an opening enters the striking range of the striking plate 335, the packaging bag loses the support of the non-powered roller group 334 and is struck by the striking plate 335. The material inside the packaging bag will be further crushed. The impact on the packaging bag will cause the material to move inside the packaging bag, thereby deforming and opening the opening. This effectively realizes the bag breaking and feeding process, and can also crush the material, making it more suitable for the batching and processing of agglomerated materials. The weighing belt conveyor 32 serves to record the weight of materials during batching.

[0024] The cutting blade 333 is preferably a power-driven saw blade; Furthermore, the two striking plates 335 are arranged at a planar angle, and the angle is preferably 90 degrees. This configuration allows the material to surge to one side of the other striking plate 335 after one striking plate 335 strikes and squeezes the packaging bag, thus effectively providing space for the deformation of the packaging bag.

[0025] Furthermore, it also includes a packaging bag guiding mechanism 336 installed above the conveyor 331. The packaging bag guiding mechanism 336 includes a limiting member 3361 installed between two striking plates 335. The limiting member 3361 is obliquely upward toward the unpowered roller group 334.

[0026] The packaging bag guiding mechanism 336 also includes a guide 3362 parallel to the conveying direction of the conveyor 331, and the guide 3362 is connected to the bottom of the limiting member 3361. A waste channel 3363 for the packaging bag to pass through is provided between the guide 3362 and the conveyor 331.

[0027] The end of the guide 3362 is set downward and extends out of the feeding hopper 332 to guide the empty packaging bags out of the bag breaking and feeding machine 33 for easy subsequent collection and processing.

[0028] Specifically, the pre-crusher 31 includes a mounting frame 3134, on which a rolling motor 3131 and a rolling roller 3132 are mounted, and the rolling motor 3131 and the rolling roller 3132 are connected in a transmission. The pre-crusher 31 also includes multiple lifting guide rods 3133 inserted into the mounting frame 3134. Both ends of the lifting guide rods 3133 are mounted on the frame 311, and springs for applying pressure to the mounting frame 3134 are sleeved on the lifting guide rods 3133. The springs can be installed on the lifting guide rods 3133 below the mounting frame 3134, and the top and bottom of the springs are fixedly connected to the mounting frame 3134 and the frame 311, respectively; or springs can be sleeved on the lifting guide rods 3133 above and below the mounting frame 3134.

[0029] The crushing roller 3132 includes a rotating main shaft 31321 rotatably connected to the mounting frame 3134. Two mounting plates 31322 are mounted on the rotating main shaft 31321. A plurality of small crushing rollers 31323 are mounted between the two mounting plates 31322. The plurality of small crushing rollers 31323 are distributed in a ring around the rotating main shaft 31321 as the central axis, and the length of the small crushing rollers 31323 is greater than the width of the packaging material.

[0030] In this type of crushing mechanism 313, after the material enters the crushing channel 314, it will squeeze the crushing roller 3132, thereby causing the crushing roller 3132 to carry the mounting frame 3134 to rise on the lifting guide rod 3133. The rising of the mounting frame 3134 will squeeze the spring installed on the lifting guide rod 3133. When the spring is deformed, it will generate a reaction force, thereby causing the crushing roller 3132 to clamp the packaging bag material. Because the crushing roller 3132 is driven by the crushing motor 3131, the crushing roller 3132 will rotate, thereby pushing the packaging bag material forward. The crushing roller 3132 is formed by several small crushing rollers 31323 set on the mounting plate 31322 and cooperating with the rotating main shaft 31321. When the crushing roller 3132 rotates, the small crushing rollers 31323 will squeeze the packaging bag material. Because the small crushing rollers 31323 have a small area, they will embed into the packaging bag when they come into contact with and squeeze the packaging bag material, making the crushing effect better and effectively ensuring that the packaging bag material is pushed forward.

[0031] Example 2: Please see Figure 6 As another operating condition, unlike the first embodiment, there are two sets of stacking station 2 and batching crushing device 3. The two sets of stacking station 2 are located at both ends of the gantry robot 1 station. The two batching crushing devices 3 share a pre-crusher 31. The other two weighing belt conveyors 32 are set up close to the pre-crusher 31. Two bag breaking feeders 33 are installed on the outside of the two close to the pre-crusher 31. A bag collection area can be set between the bag breaking feeder 33 and the stacking station 2.

[0032] When using this invention: One gantry machine can be used in conjunction with two stacking stations 2 and a batching and crushing device 3, thereby greatly improving efficiency and increasing production cycle time.

[0033] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
