[0024] In the prior art, during the operation of the unpacking device, materials that are easy to absorb moisture and form lumps and have poor fluidity are transported by their own weight after unpacking, and are very likely to stick to the wall, thereby accumulating more and more and finally causing blockage. The embodiment of the present invention provides the following solution:

[0025] like Figures 1 to 4 As shown, an embodiment of the present invention provides a material unpacking device, including a material conveying mechanism 1, a bag breaking mechanism 2, a conveying mechanism 3, a screening mechanism 4, a feeding mechanism 5 and a waste bag collecting mechanism 6; the output end of the material conveying mechanism 1 is connected to the input end of the bag breaking mechanism 2, the output end of the bag breaking mechanism 2 is connected to the input end of the conveying mechanism 3, the output end of the conveying mechanism 3 is connected to the input end of the screening mechanism 4, and the output end of the screening mechanism 4 is respectively connected to the feeding mechanism 5 and the waste bag collecting mechanism 6.

[0026] The conveying mechanism 3 includes a conveying mechanism body 31, a first driving mechanism 32 and a feed shaft 33. The first driving mechanism 32 is installed at one end of the conveying mechanism body 31. The feed shaft 33 is arranged in the conveying mechanism body 31 and leads to the input end of the screening mechanism 4. One end of the feed shaft 33 is connected to a spiral blade 34, and the other end of the feed shaft 33 is connected to the driving end of the first driving mechanism 32.

[0027] It should be noted that after the entire device is started, the material in the packaging bag is placed on the material conveying mechanism 1 by a robot or manually, and the material is sent to the bag breaking mechanism 2 for cutting. The material and the packaging bag cut into several sections enter the conveying mechanism 3. In the conveying mechanism 3, the first driving mechanism 32 drives the feed shaft 33 to rotate, so that the spiral blade rotates, thereby forcibly feeding the material and the packaging bag into the screening mechanism 4 together, avoiding the sticky material from blocking the input port of the screening mechanism 4. In the screening mechanism 4, the spiral belt structure is arranged inside the rotating screening cylinder. After the material and the packaging bag are separated, the material is sent to the feeding mechanism 5, and the packaging bag is sent to the waste bag collection mechanism 6.

[0028] In some embodiments, the first driving mechanism 32 includes a first driving motor 321, a first reduction box 322 and a first driving shaft seat 323, and the first driving shaft seat 323 is connected to one end of the conveying mechanism body 31.

[0029] It should be noted that after the first driving motor 321 rotates, power is output through the first reduction box 322, so that the first driving shaft 3231 rotates, thereby driving the feeding shaft 33 to rotate.

[0030] In some embodiments, a bearing groove is provided in the first drive shaft seat 323 , and a bearing 3232 sleeved on the first drive shaft 3231 is provided in the bearing groove, so that the first drive shaft 3231 is more stable and accurate when rotating, thereby improving the overall accuracy.

[0031] In some embodiments, the first drive shaft seat 323 is connected to one end of the conveying mechanism body 31 through a sealing ring 324. It should be noted that the sealing ring 324 can be placed to prevent leakage to the outside, thereby preventing the environment from being polluted.

[0032] In some embodiments, a purge mechanism is provided outside the conveying mechanism body 31 , and a purge end of the purge mechanism leads to the inside of the conveying mechanism body 31 .

[0033] It should be noted that the purging mechanism can be connected to compressed gas to blow the materials remaining on the inner wall of the conveying mechanism body 31 toward the screening mechanism 4 through pulse blowing.

[0034] In some embodiments, the spiral blade 34 is in a tooth-shaped structure. It should be noted that the spiral blade 34 of this shape can prevent the material and the cut packaging bag from being stuck in the conveying mechanism body 31 during the moving process, and the tooth-shaped structure also plays a role of buffering and reducing drag.

[0035] In some embodiments, the bag breaking mechanism 2 includes a bag breaking mechanism body 21, a rotating shaft 22, and a second driving mechanism 23. The bag breaking mechanism body 21 is connected to the conveying mechanism body 31, and the second driving mechanism 23 is installed on one side of the bag breaking mechanism body 21. The rotating shaft 22 is disposed in the bag breaking mechanism body 21, and the rotating shaft 22 is provided with a plurality of cutting knives 24, and one end of the rotating shaft 22 is connected to the driving end of the second driving mechanism 23.

[0036] It should be noted that the second driving mechanism 23 drives the rotating shaft 22 to rotate, thereby driving the cutting knife 24 to rotate, thereby achieving the cutting operation of the material and the packaging bag.

[0037] In some embodiments, the second driving mechanism 23 includes a second driving motor 231, a second reduction gearbox 232 and a second driving shaft seat 233, and the second driving shaft seat 233 is installed at one end of the bag breaking mechanism body 21; a rotatable second driving shaft is provided in the second driving shaft seat 233, one end of the second driving shaft is connected to the rotating shaft 22, and the other end of the second driving shaft is connected to the output end of the second reduction gearbox 232, and the input end of the second reduction gearbox 232 is connected to the motor shaft of the second driving motor 231.

[0038] It should be noted that after the second driving motor 231 rotates, it outputs power through the second reduction box 232, so that the second driving shaft rotates, thereby driving the rotating shaft 22 to rotate.

[0039] In some embodiments, the top of the bag breaking mechanism body 21 is connected to the bottom of the conveying mechanism body 31 via bolts 7 .

[0040] In some embodiments, the bag breaking mechanism 2 is provided with a protective cover 8, thereby improving safety and also preventing dust from leaking out, thus avoiding environmental pollution.

[0041] In some embodiments, the feeding mechanism 5 includes a lower hopper 51, a scraper 52, a lower material port 53 and a motor 54. The lower hopper 51 is a cylindrical structure, and the lower material port 53 is located at one side of the bottom of the lower hopper 51. The scraper 52 is disposed in the lower hopper 51, the motor 54 is installed at the bottom of the lower hopper 53, and the motor shaft of the motor 54 is connected to the scraper 52.

[0042] It should be noted that the bottom of the lower hopper 51 is horizontal, and the angle between the side wall and the bottom of the lower hopper 51 is close to 90 degrees, so that the phenomenon of material sticking to the wall can be reduced. After the motor 54 rotates, it drives the scraper to rotate, so as to scrape the material from the bottom to the lower material port 53 and send it to the downstream conveying equipment to avoid the accumulation of sticky materials and blockage.

[0043] In some embodiments, the screening mechanism 4 is provided with a dust collector 9 , which prevents dust from leaking out through the negative pressure effect generated by the fan in the dust collector 9 , and at the same time, the collected dust falls back into the lower hopper 51 .

[0044] In summary, the embodiment of the present invention provides a material unpacking device, wherein a conveying device with spiral blades is provided between the bag breaking mechanism and the screening mechanism, and after the material and the packaging bag are cut, the spiral blades are driven to rotate to convey the material and the packaging bag into the screening mechanism, thereby preventing the sticky material from being blocked at the input port of the screening mechanism. In addition, a cylindrical material discharge hopper is provided to enable smoother material discharge, and by driving the scraper in the material discharge hopper, the material can be quickly scraped into the material discharge port, thereby avoiding the accumulation of sticky materials and causing blockage.
