[0025] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0027] refer to Figure 1-4 The present application discloses a semi-automatic unpacking device, comprising a frame 1, a conveying assembly 2 connected to the frame 1 and used for conveying powder bags, a cutter 31 connected to the frame 1 and used for cutting the powder bags, a receiving box 4 connected to the frame 1 and used for accommodating the cut powder bags, a feeding pipe 43 connected to the receiving box 4 and connected to a receiving cavity 41 of the receiving box 4, and a negative pressure pump connected to the feeding pipe 43 and used for generating negative pressure in the feeding pipe 43. The conveying assembly 2, the cutter 31, and the receiving box 4 are sequentially arranged on the frame 1 along the conveying direction of the powder bags, and the side wall of the receiving box 4 is connected with an operating door 45 which is easy to open and used for closing the receiving cavity 41.

[0028] In the present invention, the powder bag is sent into the containing box 4 on the frame 1 through the conveying component 2. During the conveying process, the powder bag passes through the cutter 31, and the cutter 31 passively cuts the powder bag from the bottom of the powder bag. The cut powder bag then enters the containing chamber 41 of the containing box 4. At this stage, the operator can open the side operating door 45, manually lift the powder bag, expose the bottom of the powder bag, so that the powder can fall freely. The negative pressure pump is connected to the conveying pipe 43 and forms a negative pressure in the containing chamber 41. When the operator lifts the powder bag, the negative pressure pump causes the fallen powder to be quickly attracted to the conveying pipe 43, thereby reducing the diffusion of dust in the air and effectively controlling the dust pollution in the working environment; wherein the other end of the conveying pipe 43 can be connected to the next processing station or storage container to realize the continuous conveying of powder. The semi-automatic unpacking device involved in the present application realizes semi-automatic powder bag processing. Compared with the traditional full manual unpacking, it improves work efficiency, reduces manual operation errors, improves the working environment, and reduces occupational health risks.

[0029] Figure 1 The direction of the middle arrow is the direction of powder bag conveying.

[0030] The conveying assembly 2 includes a conveying platform 20 connected to the frame 1, a plurality of conveying rollers 21 rotatably connected to the conveying platform 20, and a first driving member 22 connected to the conveying platform 20 and used to drive at least one of the plurality of conveying rollers 21 to rotate, and the plurality of conveying rollers 21 are arranged in sequence along the conveying direction of the powder bag; the frame 1 is also connected to a bag cutting platform 3, the bag cutting platform 3 is located between the receiving box 4 and the conveying platform 20, there are a plurality of cutters 31, the plurality of cutters 31 are connected to the bag cutting platform 3, and the virtual connecting line between the plurality of cutters 31 is perpendicular to the conveying direction of the powder bag; a material door 42 for closing the receiving chamber 41 is connected to the side of the receiving box 4 close to the bag cutting platform 3, and a second driving member 421 for opening the material door 42 is connected to the side wall of the receiving box 4.

[0031] The powder bag is first placed on the conveying platform 20 and supported and guided by a plurality of conveying rollers 21 arranged in the conveying direction. At least one of the conveying rollers 21 is driven by a first driving member 22 to ensure that the powder bag moves smoothly along a predetermined path. When the powder bag is delivered from the conveying platform 20 to the bag cutting platform 3, it encounters a plurality of cutters 31 arranged perpendicular to the conveying direction. The layout of these cutters 31 allows the powder bag to be cut at multiple points (positions) at the same time.

[0032] The material door 42 of the receiving box 4 is opened, and when the powder bags reach the bag cutting platform 3 and are cut, they continue to move forward through the material door 42 and enter the receiving box 4 (pushed by the conveying roller 21). At this time, the lower part of the powder bag is cut open, and the operator lifts the powder bag from the operating door 45, and with the help of the negative pressure pump, a negative pressure environment is formed in the receiving chamber 41. The activation of the negative pressure pump causes the powder in the receiving chamber 41 to be quickly sucked into the feeding pipe 43, effectively transferring the powder from the receiving box 4 to the next processing station or storage container.

[0033] Some of the plurality of conveying rollers 21 are active rollers (driven by a motor) and some are passive rollers.

[0034] In some embodiments, a side of the conveying platform 20 away from the bag cutting platform 3 may be connected to a conveyor belt, and the conveyor belt conveys the powder bag to a conveying roller 21 on the conveying platform 20 .

[0035] A stop frame 6 is connected to the edge of the bag cutting platform 3 near the conveying platform 20, and the stop frame 6 is rotatably connected to a stop door 61 for blocking the movement of the powder bag, and the stop frame 6 is connected to a third driving member 62 for driving the stop door 61 to rotate; the conveying platform 20 and the bag cutting platform 3 are fixedly connected, and the side of the bag cutting platform 3 near the containing box 4 is rotatably connected to the frame 1 through a rotating shaft (not shown in the figure), and the frame 1 is connected to a fourth driving member 23 for driving the conveying platform 20 to rotate and lift around the rotating shaft toward the containing box 4.

[0036] When the powder bag moves along the conveying platform 20 to the bag cutting platform 3, the stop gate 61 temporarily blocks the further movement of the powder bag, ensuring that the powder bag is in the correct position for subsequent processing. When the powder bag reaches the stop gate 61 and is temporarily blocked, the fourth drive member 23 is activated, driving the conveying platform 20 and the bag cutting platform 3 to be lifted around the rotating shaft and tilted toward the receiving box 4. This rotation and lifting action raises the tail of the powder bag, thereby changing the posture of the powder bag so that the tail is higher than the front end. When the stop gate 61 is subsequently opened, the powder bag, under the action of its own gravity and with the help of the conveying roller 21 of the conveying platform 20, tilts and slides into the receiving chamber 41. Among them, the design that the tail of the powder bag is lifted ensures that the powder bag obtains additional power after the bag cutting operation and moves smoothly to the receiving box 4, reducing the resistance during the operation.

[0037] The frame 1 is connected to a controller 5 , and the stop frame 6 is connected to an infrared sensor for detecting whether the powder bag abuts against the stop frame 6 . The infrared sensor, the first drive member 22 , the second drive member 421 , the third drive member 62 , the fourth drive member 23 and the negative pressure pump are all electrically connected to the controller 5 .

[0038] When the powder bag moves along the conveying platform 20 and abuts against the stop door 61, the infrared sensor on the frame 1 detects the position of the powder bag and sends a signal to the controller 5. After receiving the signal, the controller 5 immediately activates the fourth driving member 23 to drive the conveying platform 20 to tilt around the rotating shaft, thereby lifting the tail of the powder bag. As the conveying platform 20 tilts, the second driving member 421 is activated by the controller 5 to drive the material door 42 to open. Thereafter, the third driving member 62 is started to rotate and open the stop door 61, and keep it in the open position for a certain period of time to ensure that the powder bag passes through the stop door 61 smoothly. When the powder bag completely enters the accommodating chamber 41, the material door 42 is closed by the command of the controller 5, and the stop door 61 and the conveying platform 20 are also returned to their positions. After the powder bag is safely placed in the accommodating chamber 41, the operator can open the operating door 45 for subsequent operations, manually remove the powder bag, and complete a work cycle.

[0039] In some embodiments, in order to ensure the safety of the operator, the plurality of cutters 31 can be retracted on the bag cutting platform 3 , that is, when the powder bag is not being cut, the cutters 31 can be retracted into the bag cutting platform 3 .

[0040] The semi-automatic unpacking device also includes a dust removal component 7, which includes a dust removal box 71 connected to the accommodating chamber 41, the cavity wall of the dust removal cavity 76 of the dust removal box 71 is connected to a fan 72, the fan 72 is connected to a plurality of suction pipes 73, the end of the suction pipe 73 away from the fan 72 is connected to the cavity wall of the dust removal cavity 76, and is communicated with the accommodating chamber 41, and the suction pipe 73 is connected to a filter bag 75 near the outlet of the accommodating chamber 41 for preventing dust from entering the suction pipe 73.

[0041] The fan 72 extracts air from the accommodating chamber 41 through a plurality of suction pipes 73, thereby forming a local negative pressure environment, promoting the movement of dust toward the suction pipes 73. The function of the filter bag 75 is to intercept dust particles carried in the air sucked into the suction pipes 73, and prevent the dust from being discharged to the outside of the device through the fan 72, thereby ensuring a clean working environment.

[0042] The outer wall of the dust removal box 71 is also connected with a pulse bag dust collector 74 for dust removal of the filter bag 75. The pulse bag dust collector 74 cleans the dust adhering to the surface of the filter bag 75 through a short high-pressure gas pulse, thereby maintaining the filtering efficiency of the filter bag 75 and extending its service life.

[0043] The pulse bag dust collector 74 is a prior art and will not be described in detail in this application.

[0044] One end of the feeding pipe 43 is connected to the bottom of the containing box 4, and the wall of the containing chamber 41 is connected with a grid 44 for carrying the powder bag, and the grid 44 is located above the feeding pipe 43. The grid 44 prevents the powder bag from directly abutting against the inlet of the feeding pipe 43 to prevent the powder from blocking the feeding pipe 43.

[0045] The inlet of the material conveying pipe 43 is connected to a vibrating screen 431 .

[0046] The vibrating screen 431 generates vibrations through an electric motor, and this vibration makes the powder material evenly distributed and pass through the screen. Larger particles and impurities are screened out and remain on the screen surface, preventing these large particles from entering the feed pipe 43, which may cause blockage or damage to subsequent equipment. The fine powder that passes through the screen surface enters the feed pipe 43, is sucked in by the negative pressure pump and transferred to the next processing station or storage container.

[0047] A waste bag collection port 46 is provided on the side wall of the accommodating chamber 41, and a waste bag collection bag 47 connected to the waste bag collection port 46 is connected to the outer wall of the accommodating box 4. After the powder in the powder bag is transferred, an empty powder bag is left. After the separation of the bag and the powder is completed, the operator will manually tie these waste bags in a simple knot, and then directly put them into the waste bag collection bag 47 on the outside through the waste bag feeding port on the side wall of the accommodating chamber 41.

[0048] The first driving member 22 is a motor, and the second driving member 421 , the third driving member 62 , and the fourth driving member 23 are all cylinders.

[0049] The above-mentioned multiple cylinders of the semi-automatic unpacking device of the present application use compressed air as a power source to drive various operating components, directly reducing the consumption of fossil energy, effectively reducing greenhouse gas emissions, and responding to the global trend of low-carbon environmental protection. In addition, the pneumatic system does not produce any waste gas or waste liquid during operation, keeping the working environment clean, and is particularly suitable for industries with strict environmental requirements such as pharmaceuticals and food processing. In addition, the dust removal components and negative pressure pumps of the semi-automatic unpacking device of the present application are driven by electrical energy, which also reduces the consumption of fossil energy.

[0050] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0051] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
