DETAILED DESCRIPTION

[0033] 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.

[0034] 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.).

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8The present application discloses a cutter installation structure suitable for a semi-automatic unpacking station, the cutter installation structure includes a plurality of cutter assemblies 33 connected to a bag cutting platform 3 of the semi-automatic unpacking station and used for cutting powder bags, the bag cutting platform 3 is provided with a plurality of avoidance grooves 32 running through the bag cutting platform 3, the plurality of avoidance grooves 32 correspond to the plurality of cutter assemblies 33 one by one, the cutter assembly 33 includes a knife fixing plate 331 connected to the bottom of the bag cutting platform 3, a knife fixing frame 332 connected to a side of the knife fixing plate 331 away from the bag cutting platform 3, a slide groove 3321 provided on the knife fixing frame 332, a fixing assembly 336 embedded in the slide groove 3321 and used for fixing a blade, a knife groove provided on the knife fixing plate 331 and used for matching a blade, and a fifth driving member 333 connected to the knife fixing frame 332 and used for driving the fixing assembly 336 to extend and retract along the length extension direction of the slide groove 3321, the fifth driving member 333 is used to drive the blade to extend out of the knife groove and the avoidance groove 32.

[0036] The cutter installation structure of the present application is driven by the fifth drive member 333, so that the blade can be flexibly extended and retracted under the drive of the fifth drive member 333. When a cutting operation is required, the fifth drive member 333 drives the blade to move along the slide groove 3321, pass through the knife groove and the avoidance groove 32, and cut the powder bag. After the cutting is completed, the fifth drive member 333 can drive the blade to retract back into the knife fixing frame 332, so that the blade is no longer in an exposed working state, which solves the safety hazard caused by the blade being in an extended working state in the prior art. At the same time, since the blade is extended only when needed for cutting operations, the wear of the blade is reduced, the service life of the blade is extended, and the maintenance cost of the equipment is reduced.

[0037] Reference Figure 7-12 The side wall of the tool fixing frame 332 is provided with a giving way groove 3322 connected to the slide groove 3321. The fixing assembly 336 includes a fixing sleeve 3361 embedded in the giving way groove 3322, a first clamping piece 3362 embedded in the fixing sleeve 3361, and a second clamping piece 3363 arranged opposite to the first clamping piece 3362. The blade is clamped between the first clamping piece 3362 and the second clamping piece 3363. A threaded hole for connecting a threaded rod 3364 is provided on the side of the fixing sleeve 3361 close to the giving way groove 3322. The threaded rod 3364 is used to press against the first clamping piece 3362 so that the first clamping piece 3362 cooperates with the second clamping piece 3363 to clamp the blade. In this way, the blade can be detachably replaced. When the blade needs to be replaced, the operator only needs to loosen the threaded rod 3364 to remove the blade between the first clip 3362 and the second clip 3363. The new blade can be clamped and fixed in the same way, and then the first clip 3362 and the second clip 3363 are clamped by tightening the threaded rod 3364, thereby completing the installation and fixation of the blade.

[0038] The bottom of the second clip 3363 is integrally formed with a stop plate 3365 in the horizontal direction, the bottom of the first clip 3362 is against the stop plate 3365, the fifth driving member 333 is a cylinder, the output shaft of the cylinder is connected to the driving plate 334, and the other end of the driving plate 334 is connected to a driving rod 335 for connecting the stop plate 3365. The design of the stop plate 3365 can limit the movement of the first clip 3362 relative to the second clip 3363 (limit the first clip 3362 from sliding in the vertical direction), so as to keep the relative position between the two stable. When the fifth driving member 333 (cylinder) drives the blade to perform a cutting operation, the output shaft of the cylinder pushes the driving plate 334, and the driving plate 334 is connected to the stop plate 3365 through the driving rod 335, thereby driving the first clip 3362 and the second clip 3363 to move telescopically.

[0039] In some embodiments, a protection box 34 is further connected to the bottom of the bag cutting platform 3 , and a plurality of cutter assemblies 33 are located in the protection box 34 .

[0040] In some embodiments, a knife sheath 337 is connected to the side of the knife fixing plate 331 away from the knife fixing frame 332 . The knife sheath 337 has a sheath groove that matches the cutter 31 to facilitate the passage of the cutter 31 . The knife sheath 337 can further protect the cutter 31 .

[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The present application also discloses a semi-automatic unpacking station, comprising a frame 1, a conveying assembly 2 connected to the frame 1 and used for conveying powder bags, a bag cutting platform 3 connected to the frame 1, a plurality of cutter assemblies 33 connected to the bag cutting platform 3 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 the 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 assembly 33, 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.

[0042] 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 bag cutting platform 31. The multiple cutting knife components 33 of the bag cutting platform 31 passively cut 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 action of the negative pressure pump causes the fallen powder to be quickly attracted into 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.

[0043] Figure 1 The direction of the middle arrow is the direction of powder bag conveying.

[0044] Reference Figure 1-4 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 virtual line between the cutters 31 of the plurality of cutter assemblies 33 is perpendicular to the conveying direction of the powder bag; a material door 42 for closing the accommodating cavity 41 is connected to one side of the accommodating 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 accommodating box 4.

[0045] 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.

[0046] 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.

[0047] Some of the plurality of conveying rollers 21 are active rollers (driven by a motor) and some are passive rollers.

[0048] 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 .

[0049] 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, 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.

[0050] 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.

[0051] 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 .

[0052] 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.

[0053] The semi-automatic unpacking station 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 chamber 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 chamber 76, and is communicated with the accommodating chamber 41, the suction pipe 73 is connected to a filter bag 75 near the outlet of the accommodating chamber 41 for blocking dust from entering the suction pipe 73, and the outer wall of the dust removal box 71 is also connected to a pulse bag dust collector 74 for removing dust from the filter bag 75.

[0054] 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 pipe 73. The function of the filter bag 75 is to intercept dust particles carried in the air sucked into the suction pipe 73, and prevent the dust from being discharged to the outside of the device through the fan 72, thereby ensuring the cleanliness of the working environment. The pulse bag dust collector 74 cleans the dust adhering to the surface of the filter bag 75 through short high-pressure gas pulses, thereby maintaining the filtration efficiency of the filter bag 75 and extending its service life.

[0055] The pulse bag dust collector 74 is a prior art and will not be described in detail in this application.

[0056] One end of the feed pipe 43 is connected to the bottom of the containing box 4, the cavity wall of the containing chamber 41 is connected to a grid 44 for carrying powder bags, the grid 44 is located above the feed pipe 43, a vibrating screen 431 is connected to the entrance of the feed pipe 43, a waste bag collecting port 46 is opened on the side cavity wall of the containing chamber 41, and a waste bag collecting bag 47 connected to the waste bag collecting port 46 is connected to the outer wall of the containing box 4.

[0057] The grid 44 prevents the powder bag from directly abutting against the entrance of the feed pipe 43 to prevent the powder from clogging the feed pipe 43. The vibrating screen 431 generates vibrations through an electric motor, and this vibration makes the powder evenly distributed and pass through the screen. Larger particles and impurities are screened out and left on the screen surface, preventing these large particles from entering the feed pipe 43 and possibly causing blockage or damage to subsequent equipment. The fine powder passing 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. After the powder in the powder bag is transferred, an empty powder bag is left. After completing the separation of the bag and the powder, 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.

[0058] 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.

[0059] The above-mentioned multiple cylinders of the semi-automatic unpacking station 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.

[0060] 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.

[0061] 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.
