[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] like Figures 1 to 5 As shown, the ton bag unpacking device disclosed in the embodiment of the present application includes a frame assembly 10, a collecting bin assembly 20, a sealing assembly 30 and a cutting assembly 40. The collecting bin assembly 20 is connected to the frame assembly 10. The sealing assembly 30 includes a first sealing structure 31 and a second sealing structure 32. The first sealing structure 31 and the second sealing structure 32 are both movably connected to the collecting bin assembly 20. The first sealing structure 31 and the second sealing structure 32 have a sealing state that is close to each other and a waiting state that is far away from each other. The cutting assembly 40 is connected to the frame assembly 10 and is arranged corresponding to the collecting bin assembly 20.

[0034] By applying the technical solution of the embodiment of the present application, the ton bag is transported to the collecting bin assembly 20, and the ton bag is completely placed inside the collecting bin assembly 20. The collecting bin assembly 20 is connected to the feeding port of other processing equipment. The first sealing structure 31 and the second sealing structure 32 are close to each other so that the sealing assembly 30 is in a sealing state. The ton bag is located in a closed environment formed by the sealing assembly 30 and the collecting bin assembly 20. The cutting assembly 40 cuts the ton bag, and the material falls directly into other processing equipment through the collecting bin assembly 20. The ton bag is always located inside the collecting bin assembly 20 and the sealing assembly 30 during this process, so the material will not enter the external environment and cause dust. The technical solution of the embodiment of the present application effectively solves the problem of large dust in the ton bag feeding process in the prior art.

[0035] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the collecting bin assembly 20 includes a first guide rail 21, the first guide rail 21 is located on the outer side wall of the collecting bin assembly 20, the first blocking structure 31 includes a first blocking portion 311 and a first slider, the first slider is connected to the first blocking portion 311, and the first slider is movably arranged in the first guide rail 21, and the second blocking structure 32 includes a second blocking portion 321 and a second slider, the second slider is connected to the second blocking portion 321, and the second slider is movably arranged in the first guide rail 21. The first slider and the second slider both move along the extension direction of the first guide rail 21, the first blocking portion 311 connected to the first slider and the second blocking portion 321 connected to the second slider move along the extension direction of the first guide rail 21, the first blocking portion 311 and the second blocking portion 321 are close to each other and abut against each other, so as to achieve the blocking of the collecting bin assembly 20, thereby preventing the material powder from entering the external environment and generating dust during the discharge process of the ton bag. The first guide rail 21 guides the movement of the first blocking structure 31 and the second blocking structure 32, thereby avoiding the problem that the first blocking portion 311 and the second blocking portion 321 are misaligned during movement, resulting in the two portions not being aligned to achieve a blocking state when they approach each other and abut against each other.

[0036] like Figure 1 and Figure 5 As shown, in the technical solution of this embodiment, the collecting bin assembly 20 further includes a second guide rail 22, which is located on the side of the collecting bin assembly 20 away from the frame assembly 10, and the second guide rail 22 is arranged parallel to the first guide rail 21. The first blocking structure 31 further includes a third slider, which is connected to the first blocking portion 311, and the third slider is movably arranged in the second guide rail 22. The second blocking structure 32 further includes a fourth slider, which is connected to the second blocking portion 321, and the fourth slider is movably arranged in the second guide rail 22. The third slider and the fourth slider both move along the extension direction of the second guide rail 22, and the first blocking portion 311 connected to the third slider and the second blocking portion 321 connected to the fourth slider move along the extension direction of the second guide rail 22. The first blocking structure 31 and the second blocking structure 32 are close to each other to achieve the blocking of the collecting bin assembly 20, so as to prevent the material powder from entering the outside and generating dust during the discharge process of the ton bag. The first guide rail 21 and the second guide rail 22 are respectively arranged on the side and the top of the collecting bin assembly 20, and the first sealing structure 31 and the second sealing structure 32 are moved to guide the top surface and the side wall of the two, further ensuring the smoothness of movement, reducing wear and improving service life.

[0037] The first slider can be replaced by a structure in which a bracket and a roller cooperate. The bracket is connected to the first blocking portion 311, and the roller is rotatably connected to the bracket. The roller is disposed in the first guide rail 21. When the first blocking structure 31 is moved, the roller rolls in the first guide rail 21. The bracket and the roller convert sliding friction into rolling friction, further reducing the friction force on the first blocking structure 31 during movement, making the movement more stable and improving the service life. Similarly, the second slider, the third slider, and the fourth slider can all be replaced by a structure in which a bracket and a roller are used.

[0038] like Figures 2 to 4 As shown, in the technical solution of this embodiment, the first blocking portion 311 includes a first blocking section 3111, and the second blocking portion 321 includes a second blocking section 3211. When the first blocking structure 31 and the second blocking structure 32 are in the blocking state, the projection of the collecting bin assembly 20 in the vertical direction is located inside the projection formed by the first blocking section 3111 and the second blocking section 3211 in the vertical direction. The first blocking section 3111 is located at the top of the entire first blocking structure 31, and the second blocking section 3211 is located at the top of the entire second blocking structure 32. The first blocking section 3111 and the second blocking section 3211 are close to each other, and the top opening of the collecting bin assembly 20 is blocked to prevent materials from overflowing from the top of the collecting bin assembly 20.

[0039] like Figure 4 and Figure 4As shown, in the technical solution of this embodiment, the first blocking section 3111 has a first groove, and the second blocking section 3211 has a second groove, and the first groove and the second groove are arranged correspondingly. When the first blocking structure 31 and the second blocking structure 32 are close to each other so that the blocking assembly 30 is in a blocking state, the first groove and the second groove together form a hole for the ton bag grabbing structure to pass through. During the ton bag cutting process, the grabbing structure grabs the ton bag and moves to the top of the collection bin assembly 20. The grabbing structure puts the ton bag into the collection bin assembly 20, and the blocking assembly 30 blocks the collection bin assembly 20. The grabbing structure is arranged in the hole formed by the first groove and the second groove. During the cutting process, the grabbing structure always grabs the ton bag until the grabbing structure takes out the empty ton bag after the cutting is completed. The setting of the first groove and the second groove makes it unnecessary to grab the ton bag twice when taking out the ton bag, which simplifies the operation steps and reduces the difficulty of work.

[0040] like Figures 2 to 4 As shown, in the technical solution of this embodiment, the cutting assembly 40 includes a tool structure 41 and a first drive structure 42, the first drive structure 42 is connected to the frame assembly 10, the first drive structure 42 is connected to the tool structure 41, the collection bin assembly 20 has an opening, and the tool structure 41 is partially inserted into the opening. Under the action of the grabbing structure, the ton bag is placed in the collection bin assembly 20, and the bottom side of the ton bag is arranged corresponding to the opening, the opening is located on the side wall of the collection bin assembly 20, the tool structure 41 passes through the opening to cut the ton bag, and the material flows out from the cut into the collection bin assembly 20. A photoelectric sensor is provided at the opening. When the ton bag is placed in, the photoelectric sensor sends a signal, and the cutting assembly 40 starts to cut the bottom side of the ton bag, and the use of automated cutting reduces the difficulty of operation for the staff.

[0041] like Figures 2 to 4 As shown, in the technical solution of this embodiment, the first blocking portion 311 also includes a first accommodating section 3112, the tool structure 41 is located in the first accommodating section 3112, and the second blocking portion 321 has a second accommodating section 3212, which is arranged corresponding to the first accommodating section 3112. The first accommodating section 3112 and the second accommodating section 3212 together constitute an accommodating space for the collection bin assembly 20 and the tool structure 41 to be placed, ensuring that the entire cutting process is located inside the blocking assembly 30, thereby preventing material overflow and dust generation.

[0042] like Figures 2 to 4As shown, in the technical solution of this embodiment, the first driving structure 42 includes a first driving motor 421, a gear 422, a rack 423 and a mounting seat 424, the gear 422 is connected to the output shaft of the first driving motor 421, the rack 423 is meshed with the gear 422, the mounting seat 424 is connected to the rack 423, the tool structure 41 includes a second driving motor and a tool, the second driving motor is connected to the mounting seat 424, and the tool is connected to the output shaft of the second driving motor. The first driving motor 421 drives the gear 422 to rotate, the rack 423 meshed with the gear 422 moves in the horizontal direction, and drives the mounting seat 424 to move in the horizontal direction. The tool structure 41 moves with the movement of the mounting seat 424, the second driving motor drives the tool to rotate, the tool cuts the ton bag, and the tool makes a certain length of incision on the ton bag in response to the movement of the tool structure 41. During the cutting process, only the tool portion extends into the collecting bin assembly 20 , and the remaining structures of the cutting assembly 40 are located outside the collecting bin assembly 20 , to prevent material particles from accumulating on the first driving structure 42 and affecting the operation of the first driving structure 42 .

[0043] like Figures 2 to 4 As shown, in the technical solution of this embodiment, the first blocking portion 311 also includes a first limiting section 3113, the first limiting section 3113 is connected to the first accommodating section 3112, the first limiting section 3113 and the first accommodating section 3112 together form a limiting groove, and the limiting groove is arranged corresponding to the mounting seat 424. When the blocking assembly 30 is in the blocking state, the mounting seat 424 is partially arranged in the limiting groove, the first driving motor 421 is started, and the mounting seat 424 moves along the length direction of the limiting groove. The setting of the limiting groove limits the movement of the mounting seat 424, prevents the mounting seat 424 and the rack 423 connected to the mounting seat 424 from being separated from the gear 422, and plays a certain supporting role on the mounting seat 424, thereby improving the bearing capacity of the mounting seat 424.

[0044] like Figure 1 and Figure 5 As shown, in the technical solution of this embodiment, the ton bag unpacking device also includes a driving assembly 50, and the driving assembly 50 includes a first horizontal driving structure 51 and a second horizontal driving structure 52. The output end of the first horizontal driving structure 51 is connected to the first blocking structure 31, and the output end of the second horizontal driving structure 52 is connected to the second blocking structure 32. The first horizontal driving structure 51 and the second horizontal driving structure 52 are both fixed on the frame. The first horizontal driving structure 51 and the second horizontal driving structure 52 respectively control the first blocking structure 31 and the second blocking structure 32 to move closer to or farther from each other. The setting of the first horizontal driving structure 51 and the second horizontal driving structure 52 can realize automatic control of the blocking assembly 30, further reducing the work pressure of the staff.

[0045] The ton bag unpacking device also includes an activation hopper, which is connected to the discharge port of the collection bin assembly 20. The activation hopper includes a shell, a vibration motor, a shock-absorbing spring and a conical guide portion. The conical guide portion is arranged inside the shell and has a predetermined gap with the inner wall of the shell. The vibration motor is connected to the shell to drive the shell and the conical guide portion to vibrate. The shock-absorbing spring is arranged outside the shell. Bolts are inserted into the shock-absorbing spring and connected to the collection bin assembly 20. The setting of the shock-absorbing spring avoids the problem of the activation hopper and the collection bin assembly 20 being easily detached due to the violent vibration at the connection between the activation hopper and the collection bin assembly 20. The apex of the conical guide portion is located at the upper end of the entire conical guide portion in the vertical direction. The apex of the conical guide portion extends into the material. As the vibration proceeds, the material slides along the side wall of the conical guide portion and flows out from the gap between the conical guide portion and the shell. The setting of the activation hopper avoids the problem of the material blocking the collection bin assembly 20 and causing the material to be unable to be discharged.

[0046] In summary, the purpose of this application is to provide a side-cutting unpacking machine (ton bag unpacking device) to reduce the labor intensity of the staff, improve production efficiency, reduce dust, and create a good production environment.

The reciprocating cutting system is composed of a motor (first drive motor 421), a bevel gear (gear 422), a gear bar (rack 423), an electric saw (cutter structure 41), etc. The motor drives the bevel gear to rotate, and the bevel gear drives the gear bar to achieve reciprocating motion. A bracket (mounting seat 424) is installed on the gear bar, and an electric saw is fixed on the bracket. The electric saw moves to achieve cutting action. The cover system consists of an outer cover plate, rollers, and a cylinder (drive component 50), etc. The cylinder push rod is connected to the outer side of the outer cover plate, and the roller is fixed to the inner side of the outer cover plate. A guide rail is set at a suitable position on the outer wall of the chute bin, and the roller is installed on the guide rail. The cylinder pushes the cylinder to open and close the bag. The ton bag is lifted by the crane and placed in the chute bin. The cover system is closed, and the reciprocating cutting system is started to cut the ton bag. The material falls from the incision into the chute bin. In order to prevent the material from blocking the chute bin, an activation hopper is installed. A screen box is installed under the activation hopper. A screen plate is installed in the screen box to filter the material. The debris is left on the screen plate and can be taken out by opening the screen box cover. After all the materials in the ton bag are discharged, the cover system is opened, and the empty bag is pulled up by the crane and returned to the ton bag storage place.
