Description

Technical Field

[0001] The utility model belongs to the technical field of blanking devices, and particularly relates to a ton bag beating and blanking device. Background Art

[0002] In the production of the lithium battery industry, most production raw materials are powders, which are mostly packed in ton bags. The feeding methods are mostly manual and traditional hoisting feeding methods. However, manual feeding has a high labor intensity, a harsh working environment, and too much dust, which affects the health of workers. And due to other reasons such as high humidity, easy adhesion, and small particles of the powder material itself in the traditional feeding method, the raw material blanking is slow and blocked, and manual intervention is required for normal blanking, resulting in low feeding efficiency. Since the metal powder of lithium batteries is used in large quantities, packed in ton bags, and has a large weight, it is not conducive to handling. And under the influence of factors such as high humidity, easy adhesion, and small particles, the raw materials are prone to caking and other phenomena, resulting in problems such as slow blanking and blockage. Especially, the materials at the bottom of the ton bag are more unfavorable for discharging under the heavy pressure for a certain period of time. The applicant's prior application CN 221543382 U discloses an adjustable ton bag feeding device, belonging to the field of ton bag feeding stations. The key points of its technical solution include a bracket, an inlet box is arranged on the bracket, a plurality of beating mechanisms are arranged on the bracket. The beating mechanism includes a base, a mounting plate is rotatably connected to the base, a beating cylinder is arranged on the mounting plate, and a positioning component for adjusting the angle of the mounting plate is arranged between the base and the mounting plate. The beating mechanism is slidably arranged on the bracket, and an adjusting part for fixing the position of the beating mechanism is arranged on the bracket. By setting the positioning component and the adjusting part, the beating mechanism can adjust its position on the bracket and can flexibly adjust the beating cylinder to any angle to meet the needs of ton bags of different sizes, with stronger applicability and higher utilization rate. However, this device cannot adaptively adjust the beating direction of the ton bag during the blanking process, nor can it judge the material conditions in each direction, and the feeding effect is still not ideal.

[0029] Referring to Figure 1-7 As shown, a ton bag slapping and discharging device includes a frame 1, a feeding bin 2, a slapping mechanism 3, a bag clamping mechanism 4 and a weight sensor 5. The feeding bin 2 is provided with a feeding port 21, a discharging port 22, a material distributing grille 23 and a bin door 24. The feeding port 21 and the discharging port 22 are relatively arranged at the upper and lower ends of the feeding bin 2. The material distributing grille 23 is horizontally laid inside the feeding bin 2. The bin door 24 is arranged on the front of the feeding bin 2. The slapping mechanism 3 is provided with a discharging platform 31, a slapping cylinder 32 and an adjusting cylinder 33. The discharging platform 31 is arranged above the feeding port 21. A discharging opening 311 opposite to the feeding port 21 is arranged at the center of the discharging platform 31. The slapping cylinder 32 is arranged around the discharging platform 31 and its lower end is hinged to the frame 1. The lower end of the adjusting cylinder 33 is hinged to the frame 1 and the cylinder rod is connected to the upper part of the slapping cylinder 32. The bag clamping mechanism 4 is arranged between the feeding bin 2 and the discharging platform 31. The bag clamping mechanism 4 is provided with a bag clamping ring 41 and a bag clamping cylinder 42. The bag clamping ring 41 is arranged opposite to the feeding port 21. The bag clamping cylinder 42 is arranged on both sides of the feeding bin 2 and connected to the bag clamping ring 41. The discharging platform 31 is provided with support legs 34, support rods 35 and a feeding support 36. The support legs 34 are arranged on the frame 1 corresponding to the slapping cylinders 32 one by one. The support rods 35 are arranged at the upper ends of the support legs 34. The feeding support 36 is arranged opposite to the feeding port 21 and connected to the support rods 35. The weight sensor 5 is arranged between the support legs 34 and the frame 1.

[0030] The ton bag is placed on the slapping mechanism 3 by a crane or a forklift, and the lower opening of the ton bag is clamped with the feeding port 21 through a bag clamping assembly. During the discharging process, the side of the ton bag opening is slapped by the slapping cylinder 32 to extrude the internal material. According to needs, the slapping mode can be set to slap simultaneously, or take turns to slap, or slap relatively alternately, or adopt the foregoing combination to take turns to slap.

[0031] After the material enters the feeding bin 2, the feeding bin 2 is a closed bin to avoid the diffusion of dust generated during the discharging process. The material distributing grille 23 crushes the agglomerated material.

[0032] The bulk bag is received by the feeding support 36, and the bag mouth passes through the feeding port at the center of the feeding support 36 and the bag clamping ring 41 at the lower part; the weight sensor 5 is used to sense the material weight in all directions of the discharging platform. When the material in a certain direction is heavier than that in other directions, it indicates that the discharging speed of the material on this side is slow. Then, the discharging cylinder on this side is started, or the discharging action is accelerated to pat the material. Meanwhile, the discharging angle is adjusted up and down by the adjusting cylinder 33 to find different discharging angles until the pressures in all directions are equal and the original patting steps are restored.

[0033] Further, the flapping cylinder 32 is provided with a support plate 321, a cylinder plate 322, a flapping plate 323 and a rubber pad 324. The support plate 321 is connected to the frame 1, the cylinder plate 322 is hinged to the upper support plate 321, the flapping cylinder 32 is fixed on the cylinder rod, the flapping plate 323 is arranged at the front end of the flapping cylinder 32, and the rubber pad 324 is arranged on the flapping plate 323; the front end of the adjusting cylinder 33 is connected to the cylinder plate 322.

[0034] The flapping cylinder 32 realizes different flapping modes for the materials in the bulk bag through the control box, and combines with the weight sensor 5 and the pressure sensor to realize its control, and together with the auxiliary feeding mechanism, realizes the feeding of the materials in the bulk bag.

[0035] Further, an observation window 241 and a glove port 242 are provided on the bin door 24. A scraping rod 243 is provided on the observation window 241. A rotating rod 244 is provided at the outer end of the scraping rod 243, and a scraping plate 245 is provided at the inner end and fits with the observation window 241.

[0036] The observation window 241 is used to observe the material situation in the crushing bin. The scraping rod 243 is controlled by the rotating rod 244 to scrape the dust on the inner side of the observation window 241 clean through the scraping plate 245. The glove ports 242 are arranged on both sides of the observation window 241 and are provided with operating gloves for cleaning the materials that cannot be handled by the pushing component.

[0037] Further, a gasket 211 is provided between the feeding port 21 and the bag clamping ring 41.

[0038] The setting of the gasket 211 can better clamp the bag mouth and avoid damage.

[0039] Further, the feeding bin 2 is also provided with a small door 25 and an exhaust filter cartridge 26. The small door 25 is arranged on one side of the feeding bin 2, and the exhaust filter cartridge 26 is arranged on the rear side of the feeding bin 2.

[0040] The door can quickly handle the lumps in the crushing bin; the exhaust filter cartridge 26 discharges the air pressure generated during the feeding process, which is beneficial to feeding.

[0041] Further, a pneumatic hammer 27 is provided on the side of the discharge port 22, and the pneumatic hammers 27 are evenly distributed on the side of the discharge port 22.

[0042] The pneumatic hammer 27 can assist the material to pass through the feeding grille and the discharge port 22 to crush the material.

[0043] Furthermore, the feeding support 36 is provided with a first support ring 361, a second support ring 362, a connecting rod 363 and a supporting convex rod 364. The first support ring 361 is larger than the second support ring 362. The first support ring 361 is connected to the two side support rods 35 through the connecting rod 363. The second support ring 362 is arranged below the first support ring 361 and is connected to the first support rod 35 through the supporting convex rod 364. The supporting convex rods 364 are distributed at intervals between the first support rod 35 and the second support rod 35 and protrude towards the inside of the feeding support 36.

[0044] The first support ring 361 and the second support ring 362 form a funnel-shaped feeding support 36, which can better support the ton bag and form a feeding trend. By setting the supporting convex rods 364, the material entering the feed port 21 can be separated to a certain extent to avoid squeezing and blocking the outlet of the ton bag.

[0045] Furthermore, a striking hammer is provided at the front end of the flapping plate 323.

[0046] The striking hammer can better break the material. The front end of the striking hammer can be in structures such as semi-circular, elliptical, corrugated, cross-shaped, etc., to improve the breaking effect.

[0047] Furthermore, pressure sensors (not shown) are respectively arranged between the flapping cylinder 32 and the adjusting cylinder 33 and the frame 1.

[0048] The pressure sensors on the flapping cylinder 32 and the adjusting cylinder 33 can detect the flapping direction. For example, when the detected pressure value is small, it indicates that the angle is too large and the material cannot be flapped well, and the flapping angle needs to be adjusted downward. Another example is that when the cylinder angles are the same, if the pressure ratio of the adjusting cylinder 33 in a certain direction to the pressure of the flapping cylinder 32 is smaller than that in other directions, it means that the flapping cylinder 32 in this direction is blocked by lumps and the advancing length is small, then the frequency of the flapping cylinder 32 in this direction is increased. If the pressure values of the adjusting cylinder 33 and the flapping cylinder 32 in a certain direction are larger than those in other directions, it means that the material deviates to this side or the material feeding speed on this side is slow, then the frequency of the flapping cylinder 32 is increased, or the angle of the flapping cylinder 32 is increased to push the material to the other side. The pressure sensors and the weight sensor 5 jointly obtain the material condition in the ton bag and comprehensively control the action of the bag flapping mechanism.

[0049] Furthermore, vibration damping pads are respectively arranged between the feeding bin 2, the weight sensor 5, the pressure sensors and the frame 1.

[0050] Reduce the influence of the vibration of the pneumatic hammer 27 on the sensors.

[0051] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
