[0002] In the production field, for powdery or granular items, material bags are generally used for storage and transportation, such as cement, fertilizer, flour, plastic granules, etc. For bagged items, the bags need to be unpacked when used. When the usage is small, manual unpacking is sufficient; when the usage is large, manual unpacking is used, which not only has low unpacking efficiency and cannot meet production needs, but also generates dust, polluting the environment and even endangering the health of workers. In order to improve unpacking efficiency and reduce labor intensity, material bag unpacking machines have emerged.

[0027] The present invention can achieve the beating and shaking of the material bag by setting a beating mechanism, so that the material in the material bag can quickly fall into the material drop bin from the discharge port, thereby improving the material drop efficiency; on the other hand, the remaining material in the material bag can fully fall into the material drop bin, thereby improving the material drop rate of the material bag and reducing the waste of material resources.

[0036] Furthermore, the cutting mechanism comprises a second motor, a fixed end of the second motor is connected to the frame, and a power output end of the second motor is transmission-connected to the knife shaft.

[0037] The present invention improves the cutting efficiency of the blade on the material bag by arranging a rotatable knife shaft.

[0038] Furthermore, the needle insertion mechanism is also used to transport the material bag from the slapping mechanism to the bag return mechanism, and the bag return mechanism is arranged on the frame.

[0060] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following is a brief description of the present invention in conjunction with the attached drawings. Figure 1-8 The specific embodiments of the present invention are described in detail.

[0061] In the present invention, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure.

[0062] In the present invention, terms such as "inside", "outside", "upper", and "lower" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0063] See attached Figure 1 and 2 A material bag unpacking machine includes: a frame 100, a feed table 200, and a pin insertion mechanism 300, a dust removal mechanism 400 and a cutting mechanism 500 arranged on the frame 100; the feed table 200 is located on one side of the frame 100, and the feed table 200 is used to place the material bag 201; the pin insertion mechanism 300 can reciprocate linearly relative to the frame 100, and is used to horizontally insert the middle part of the material bag 201 located on the feed table 200, and transport the material bag 201 to the dust removal mechanism 400 and the cutting mechanism 500 in sequence; the dust removal mechanism 400 is located between the feed table 200 and the cutting mechanism 500, and the dust removal mechanism 400 is used to remove dust on the outer surface of the material bag 201; the cutting mechanism 500 is located below the pin insertion mechanism 300, and the cutting mechanism 500 is used to cut a discharge port on the lower surface of the material bag 201, and make the material in the material bag 201 fall into the drop bin 110 from the discharge port.

[0064] It should be noted that the pin insertion mechanism 300 is inserted from the side of the material bag 201, and there are no other interfering structures on the upper surface of the material bag 201 and the lower surface of the material bag 201, so dust removal operations can be performed on the upper surface and the lower surface of the material bag 201 at the same time.

[0065] It should be noted that the number of material bags 201 belonging to the same layer on the feeding platform 200 is not limited, and can be one bag or more than two bags.

[0066] Therefore, the material bag unpacking machine provided by the present invention, by setting a pin insertion mechanism 300 that reciprocates linearly with the random frame 100, can insert the mobile material bag 201 from the side of the material bag 201, complete the dust removal, cutting and dropping of the material bag 201, prevent the dust on the surface of the material bag 201 from falling into the dropping bin 110 together with the material, thereby improving the purity of the material and improving the quality of products related to the material.

[0067] Preferably, see Appendix Figure 3The dust removal mechanism 400 includes an upper dust removal component 410 and a lower dust removal component 420. The upper dust removal component 410 and the lower dust removal component 420 are arranged relative to each other. When the pin mechanism 300 transports the material bag 201 to the dust removal mechanism 400, the upper dust removal component 410 removes dust from the upper surface of the material bag 201, and the lower dust removal component 420 removes dust from the lower surface of the material bag 201.

[0068] Therefore, the present invention adopts the relatively arranged upper dust removal component 410 and the lower dust removal component 420 to realize that when the pin mechanism 300 transports the material bag 201 to the dust removal mechanism 400, the upper surface and the lower surface of the material bag 201 are dusted at the same time, thereby improving the efficiency of the dust removal operation, preventing the dust on the surface of the material bag 201 from falling into the drop bin 110 together with the material, improving the purity of the material, and improving the quality of products related to the material.

[0069] Preferably, see Appendix Figure 3 The dust removal mechanism 400 also includes a first lifting assembly 430, a fixed end of the first lifting assembly 430 is connected to the frame 100, a power output end of the first lifting assembly 430 is connected to the upper dust removal assembly 410, or a power output end of the first lifting assembly 430 is connected to the lower dust removal assembly 420, or the first lifting assembly 430 is respectively connected to the upper dust removal assembly 410 and the lower dust removal assembly 420.

[0070] It should be noted that the first lifting assembly 430 may be a rack and pinion transmission mechanism, a linear module or a guide rail and slider mechanism.

[0071] It should be noted that the number of first lifting assemblies 430 is not limited and can be two, wherein the power output end of one of the first lifting assemblies 430 is connected to the upper dust removal assembly 410 , and the power output end of the other lifting assembly is connected to the lower dust removal assembly 420 .

[0072] Since the thickness of the material bags 201 is different, the present invention designs the dust removal mechanism 400 so that the distance between the upper dust removal component 410 and the lower dust removal component 420 is adjustable, so that the dust removal mechanism 400 can be applied to material bags 201 of different thicknesses, thereby improving the practicality of the unpacking machine.

[0073] Preferably, see Appendix Figure 3 The upper dust removal component 410 includes an upper vacuum suction groove 411, which is connected to the frame 100; the lower dust suction component includes a lower vacuum suction groove 421, which is connected to the frame 100.

[0074] In a specific implementation, the upper vacuum suction groove 411 and the lower vacuum suction groove 421 are respectively connected to the first end of the pipeline, and the second end of the vacuum pipeline is connected to the vacuum cleaner.

[0075] Preferably, the upper dust removal component 410 also includes an upper brush, which is used to clean the dust on the upper surface of the material bag 201 and absorb it through the upper vacuum suction groove 411; the lower dust removal component 420 also includes a lower brush, which is used to clean the dust on the lower surface of the material bag 201 and absorb it through the lower vacuum suction groove 421.

[0076] Therefore, the present invention loosens the dust on the upper and lower surfaces of the material bag 201 by arranging the upper brush and the lower brush, which is beneficial to vacuum dust removal and makes the vacuum dust removal more thorough.

[0077] Preferably, in this embodiment, the upper brush is connected to the end of the upper vacuum suction groove 411 , and the lower brush is connected to the end of the lower vacuum suction groove 421 .

[0078] Therefore, the present invention connects the upper brush and the lower brush to the ends of the upper vacuum suction groove 411 and the lower vacuum suction groove 421 respectively, so as to achieve, on the one hand, cleaning and sucking the dust on the upper and lower surfaces of the material bag 201; on the other hand, the upper brush and the lower brush are respectively in deformable contact with the upper and lower surfaces of the material bag 201, which can adapt to the uneven upper and lower surfaces of the material bag 201, thereby improving the dust removal effect and preventing the upper vacuum suction groove 411 or the lower vacuum suction groove 421 from scratching the surface of the material bag 201.

[0079] Alternatively, in other embodiments, the upper brush is located on a side of the upper vacuum suction groove 411 close to the feed table 200 and connected to the frame 100 , and the lower brush is located on a side of the lower vacuum suction groove 421 close to the feed table 200 and connected to the frame 100 .

[0080] Therefore, the present invention can also achieve the dust on the upper surface of the material bag 201 while cleaning by separating the upper brush from the upper vacuum suction groove 411 and the lower brush from the lower vacuum suction groove 421 .

[0081] Preferably, the side walls of the upper vacuum suction groove 411 and the side walls of the lower vacuum suction groove 421 are both made of flexible materials, which can adapt to the upper surface of the material bag 201 and the lower surface of the material bag 201 respectively.

[0082] It should be noted that the flexible material may be rubber or silicone.

[0083] Since the needle insertion mechanism 300 inserts the material bag 201, the surface of the material bag 201 is not flat. If the upper vacuum suction groove 411 and the lower vacuum suction groove 421 are made of rigid materials, the material bag 201 may collide with the upper vacuum suction groove 411 or the lower vacuum suction groove 421 when passing between the upper vacuum suction groove 411 and the lower vacuum suction groove 421, causing the material bag 201 to fall from the needle insertion mechanism 300, failing to achieve the dust removal effect, or scratching the upper and lower surfaces of the material bag 201, resulting in material leakage.

[0084] Therefore, the present invention designs the side walls of the upper vacuum suction groove 411 and the lower vacuum suction groove 421 to be made of flexible material, so that the upper vacuum suction groove 411 and the lower vacuum suction groove 421 can adapt to the upper and lower surfaces of the material bag 201, thereby preventing the rigid upper vacuum suction groove 411 and the lower vacuum suction groove 421 from scratching the upper and lower surfaces of the material bag 201, and preventing the material from leaking when the material bag 201 is not cut, resulting in material waste.

[0085] Preferably, see Appendix Figure 4 The pin mechanism 300 includes a first driving component, a pin bracket 310 and a pin 320. The fixed end of the first driving component is connected to the frame 100, and the power output end of the first driving component is connected to the pin bracket 310; a plurality of pins 320 are arranged side by side on the pin bracket 310.

[0086] It should be noted that the first driving assembly can be a belt drive, a chain drive mechanism, a gear rack drive mechanism, a guide rail slider mechanism, etc.

[0087] It should be noted that the first end of the insertion pin 320 has a pointed end to facilitate insertion into the material bag 201 .

[0088] Therefore, the pin mechanism 300 of the present invention, by arranging multiple pins 320 side by side, on the one hand, facilitates the insertion of multiple material bags 201 belonging to the same layer on the feed table 200, thereby improving the efficiency of conveying, vacuuming, cutting, and blanking of the material bags 201; on the other hand, multiple pins 320 insert the material bags 201 to prevent the material bags 201 from rotating with the pins 320, thereby facilitating the support of the material bags 201 and completing the vacuuming, cutting, and blanking actions.

[0089] Preferably, see Appendix Figure 5 The pin bracket 310 includes an H-shaped bracket 330 and a connecting member 340, the end of the H-shaped bracket 330 is connected to the power output end of the first driving assembly, and the connecting member 340 is vertically connected to the side of the H-shaped bracket 330;

[0090] The H-shaped bracket 330 includes a first rod 331 and a second rod 332 which are parallel to each other, and a third rod 333 which is connected to the middle of the first rod 331 and the middle of the second rod 332. The ends of the first rod 331 and the second rod 332 are connected to the power output end of the first driving mechanism. The upper ends of the connecting members 340 are respectively vertically connected to the sides of the first rod 331 and the second rod 332, and the lower ends of the connecting members 340 are connected to the pin 320. The multiple connecting members 340 close to the side of the feed table 200 can abut against the side of the material bag 201.

[0091] Therefore, the pin bracket 310 of the present invention is an H-shaped bracket 330, which can increase the rigidity of the pin insertion mechanism 300 and improve the stability and reliability of the pin insertion mechanism 300; the connecting rod 341 close to the feed table 200 can abut against the side of the material bag 201 located on the pin insertion mechanism 300, providing a limit for the insertion and removal of the material bag 201.

[0092] In one embodiment, the connector 340 is an integrated structure, and a plurality of grooves are formed at the lower end of the connector 340 , with teeth formed between the grooves, and the lower ends of the teeth are respectively connected to the pins 320 .

[0093] In another embodiment, the connecting member 340 is a split structure, and the connecting member 340 includes a plurality of connecting rods 341, and the plurality of connecting rods 341 are arranged at intervals, and the upper ends of the plurality of connecting rods 341 are respectively vertically connected to the sides of the first rod 331 and the second rod 332, and the lower ends of the plurality of connecting rods 341 are respectively connected to the pins 320, and the plurality of connecting rods 341 close to the side of the feed table 200 can abut against the side of the material bag 201.

[0094] Preferably, the intervals between any two adjacent pins 320 are equal.

[0095] Therefore, the spacing between the pins 320 of the present invention is designed to be equal, which is convenient for manufacturing and installation.

[0096] Preferably, see Appendix Figure 1 and 6 A material blocking mechanism 600 is also provided on the frame 100, and the material blocking mechanism 600 is located above the feed platform 200. The material blocking mechanism 600 includes a second lifting component 610 and a material blocking pressure plate 620. The fixed end of the second lifting component 610 is connected to the frame 100, and the power output end of the second lifting component 610 is connected to the material blocking pressure plate 620. The material blocking mechanism 600 is configured as follows: when the needle insertion mechanism 300 is in a state of horizontally inserting the middle of the material bag 201 located on the feed platform 200, the material blocking pressure plate 620 can abut against the upper surface of the material bag 201 to keep the material bag 201 on the feed platform 200; when the needle insertion mechanism 300 is in a state of completing the insertion of the material bag 201, the material blocking pressure plate 620 can be separated from the upper surface of the material bag 201.

[0097] Therefore, the present invention sets a material blocking pressure plate 620 to achieve contact or separation with the upper surface of the material bag 201, thereby ensuring the effectiveness of the needle insertion mechanism 300 in inserting the material bag 201 and preventing the material bag 201 from falling from the feed table 200 when the needle insertion mechanism 300 inserts the material bag 201.

[0098] Preferably, see Appendix Figure 6The material blocking mechanism 600 also includes a material blocking side plate 630, which is connected to the material blocking pressure plate 620. The material blocking mechanism 600 is configured as follows: when the needle insertion mechanism 300 is in a state of horizontally inserting the middle of the material bag 201 located on the feed platform 200, the material blocking side plate 630 can abut against the side of the material bag 201 to keep the material bag 201 on the feed platform 200; when the needle insertion mechanism 300 is in a state of completing the insertion of the material bag 201, the material blocking side plate 630 can be separated from the side of the material bag 201.

[0099] It should be noted that the material blocking side plate 630 is located on a side away from the pin insertion mechanism 300 .

[0100] The material blocking side plate 630 may be an integral structure or a split structure.

[0101] Therefore, the present invention sets a material blocking side plate 630 connected to the material blocking pressure plate 620 to achieve abutment and separation with the side of the material bag 201, thereby ensuring the effectiveness of the needle insertion mechanism 300 in inserting the material bag 201 and preventing the material bag 201 from falling from the feed table 200 when the needle insertion mechanism 300 inserts the material bag 201.

[0102] Preferably, see Appendix Figure 6 The material blocking mechanism 600 also includes a material blocking pressure bar 621, and multiple material blocking pressure bars 621 are arranged side by side on the material blocking pressure plate 620, and multiple material blocking pressure bars 621 can abut against or separate from the upper surface of the material bag 201; and / or, the material blocking side plate 630 includes multiple material blocking side rods 631, and multiple material blocking side rods 631 are respectively connected to the material blocking pressure plate 620, and multiple material blocking side rods 631 can abut against or separate from the side of the material bag 201.

[0103] It should be noted that the material-blocking strip 621 may be a cylindrical strip, a triangular strip, a rectangular strip or a semicircular strip.

[0104] Therefore, the present invention arranges a plurality of material retaining strips 621 on the material retaining pressure plate 620 to convert the large plane contact into a plurality of small plane contacts or line surface contacts, thereby further improving the clamping effect on the material bag 201 and preventing the material bag 201 from falling from the feed table 200 when the needle mechanism 300 inserts the material bag 201.

[0105] Preferably, see Appendix Figure 1 and 7 The needle insertion mechanism 300 is also used to transport the material bag 201 from the cutting mechanism 500 to the flapping mechanism 700. The flapping mechanism 700 is arranged on the frame 100. The flapping mechanism 700 is located below the needle insertion mechanism 300 and adjacent to the cutting mechanism 500. The flapping mechanism 700 is used to flap the material bag 201 and make the remaining material in the material bag 201 fall into the drop bin 110 from the discharge port.

[0106] It should be noted that the material drop bin 110 is located below the cutting mechanism 500 and the beating mechanism 700 .

[0107] Since the discharge port is cut out of the lower surface of the material bag 201 only by the cutting mechanism 500, the material in the material bag 201 falls into the drop bin 110 from the discharge port by its own weight, and there will be a high amount of residual material in the material bag 201, resulting in a waste of resources.

[0108] Therefore, the present invention can achieve the beating and shaking of the material bag 201 by setting up the beating mechanism 700, so that the material in the material bag 201 can quickly fall into the material drop bin 110 from the discharge port, thereby improving the material drop efficiency; on the other hand, the remaining material in the material bag 201 can be fully dropped into the material drop bin 110, thereby improving the material drop rate of the material in the material bag 201 and reducing the waste of material resources.

[0109] Preferably, see Appendix Figure 7 The flapping mechanism 700 includes a first motor 710 and a flapping assembly 720. The flapping assembly 720 includes a first rotating shaft 721 and a first flapping piece 722. The fixed end of the first motor 710 is connected to the frame 100. The power output end of the first motor 710 is transmission-connected to the first rotating shaft 721. The axial direction of the first rotating shaft 721 is perpendicular to the movement direction of the pin insertion mechanism 300. A plurality of first flapping pieces 722 are arranged side by side and tilted on the first rotating shaft 721. The plurality of first flapping pieces 722 can rotate to flap the material bag 201 and allow the remaining material in the material bag 201 to fall from the discharge port into the drop bin 110.

[0110] It should be noted that the included angle between the first flapping piece 722 and the first rotating shaft 721 is between 30° and 60°.

[0111] Since the first flapping piece 722 is tiltedly arranged on the first rotating shaft 721, when the first rotating shaft 721 drives the first flapping piece 722 to rotate, when the first rotating shaft 721 rotates 180°, the angle between the first flapping piece 722 and the first rotating shaft 721 changes from a positive angle to a negative angle, and the first flapping piece 722 swings the material bag 201, so that the remaining material in the material bag 201 falls into the drop bin 110 from the discharge port.

[0112] Therefore, the present invention sets an inclined flap on the first rotating shaft 721. When the first rotating shaft 721 drives the first flap 722 to rotate, the first flap 722 swings the material bag 201, changes the posture of the material bag 201, and makes the remaining material in the material bag 201 fall into the drop bin 110, thereby improving the drop rate of the material in the material bag 201 and reducing the waste of material.

[0113] Preferably, see Appendix Figure 7The number of flapping components 720 is at least two groups, and the flapping components 720 also include a second rotating shaft 723 and a second flapping piece 724. The second rotating shaft 723 is parallel to the first rotating shaft 721. Multiple second flapping pieces 724 are arranged side by side and tilted on the second rotating shaft 723. The multiple second flapping pieces 724 can rotate to flap the material bag 201 and make the remaining material in the material bag 201 fall into the drop bin 110 from the discharge port.

[0114] In one embodiment, the power output end of the first motor 710 is transmission-connected to the second rotating shaft 723 .

[0115] Therefore, the present invention sets two groups of beating components 720 to increase the contact area with the material bag 201 in the moving direction of the material bag 201, and beats the material bag 201 multiple times, so that the remaining material in the material bag 201 can fully fall into the drop bin 110 from the discharge port, thereby improving the drop efficiency of the material, increasing the drop rate of the material in the material bag 201, and reducing material waste.

[0116] Preferably, the second beating piece 724 and the first beating piece 722 are arranged in an eight-shape.

[0117] Therefore, the present invention arranges the first flapping piece 722 and the second flapping piece 724 in an eight-shape, and the angles between the first flapping piece 722 and the second flapping piece 724 and the rotating shaft change in opposite directions, so that the flapping effect on the material bag 201 is large, and the posture of the material bag 201 changes greatly, so that the remaining material in the material bag 201 can fully fall into the drop bin 110 from the discharge port, thereby improving the drop efficiency of the material, increasing the drop rate of the material in the material bag 201, and reducing the waste of material.

[0118] Preferably, see Appendix Figure 7 The cutting mechanism 500 includes a knife shaft 510 and a blade 520. The axial direction of the knife shaft 510 is perpendicular to the movement direction of the pin insertion mechanism 300. Multiple blades 520 are arranged side by side on the knife shaft 510. The multiple blades 520 are used to cut a discharge port on the lower surface of the material bag 201 and make the material in the material bag 201 fall into the drop bin 110 from the discharge port.

[0119] In this embodiment, the blade 520 is a circular blade 520 .

[0120] Therefore, the present invention arranges a plurality of blades 520 side by side on the blade shaft 510 to increase the contact area between the blades 520 and the material bag 201, increase the number of discharge ports of the material bag 201, and improve the material dropping efficiency.

[0121] Preferably, see Appendix Figure 7The cutting mechanism 500 includes a second motor 530 , a fixed end of the second motor 530 is connected to the frame 100 , and a power output end of the second motor 530 is transmission-connected to the knife shaft 510 .

[0122] Therefore, the present invention improves the cutting efficiency of the blade 520 on the material bag 201 by providing a rotatable blade shaft 510 .

[0123] Preferably, see Appendix Figure 7 , the spacing between two adjacent blades 520 is equal.

[0124] Preferably, see Appendix Figure 1 and 4 The needle insertion mechanism 300 is also used to transport the material bag 201 from the slapping mechanism 700 to the bag withdrawal mechanism 800. The bag withdrawal mechanism 800 is arranged on the frame 100. The bag withdrawal mechanism 800 is used to prevent the material bag 201 from moving with the needle insertion mechanism 300, so that the material bag 201 falls off the needle insertion mechanism 300.

[0125] Therefore, the present invention sets a bag-returning mechanism 800 to enable the material bag 201 without material to fall off the pin-insertion mechanism 300, thereby achieving automatic recovery of the material bag 201 without the need for workers to recover the material, thereby reducing the labor intensity of the workers.

[0126] Preferably, see Appendix Figure 4 The bag return mechanism 800 includes a material return bracket and a blocking block 820. The material return bracket is connected to the frame 100. The blocking block 820 is arranged on the material return bracket. The blocking block 820 is used to prevent the material bag 201 from moving with the needle insertion mechanism 300, so that the material bag 201 falls off from the needle insertion mechanism 300.

[0127] Therefore, the present invention uses the blocking block 820 to block the material bag 201 from moving with the pin mechanism 300, thereby increasing the contact area with the material bag 201 and improving the success rate of the material bag 201 falling off from the pin mechanism 300. It has a simple structure, is easy to implement, and has a low manufacturing cost.

[0128] It should be noted that the blocking block 820 can be an integral structure or a split structure.

[0129] In one embodiment, the blocking block 820 is an integrated structure, and a plurality of grooves are formed at the upper end of the blocking block 820 , and blocking bars 821 are formed between the grooves.

[0130] In another embodiment, see the attached Figure 4 The blocking block 820 is a split structure, and includes a plurality of blocking bars 821 . The plurality of blocking bars 821 are arranged at intervals, and the lower ends of the plurality of blocking bars 821 are connected to the bag return bracket 810 .

[0131] Preferably, any blocking bar 821 is located between two adjacent insertion pins 320 , and the upper end of the blocking bar 821 is located at a height higher than the insertion pins 320 .

[0132] Therefore, the present invention increases the success rate of bag return by limiting the height of the upper end of the blocking strip 821 to be higher than the height of the insertion pin 320 .

[0133] Preferably, see Appendix Figure 8 , and also includes a material bag recovery bin 120, which is located below the bag return mechanism 800.

[0134] Therefore, the present invention provides a material bag recovery bin 120 below the bag return mechanism 800 for storing the material bags 201 .

[0135] Preferably, a lifting mechanism is also included, the power output end of the lifting mechanism is connected to the feeding platform 200, and the lifting mechanism is used to move the material bag 201 on the feeding platform 200 to a specified height.

[0136] It should be noted that the lifting mechanism can be a scissors-type lifting mechanism, a guide rail lifting mechanism, a chain lifting mechanism, etc.

[0137] It should be noted that the designated height is the position where the needle insertion mechanism 300 inserts the material bag 201 .

[0138] In a specific implementation, a distance measuring sensor is included, and the distance measuring sensor is used to detect the height of the feeding platform 200 .

[0139] Preferably, it further includes a shell 130 , which is covered on the frame 100 .

[0140] Therefore, the present invention provides the shell 130 to prevent dust from leaking out when the material in the material bag 201 falls out, polluting the environment, and even endangering the health of the workers.

[0141] Working principle of the present invention:

[0142] The lifting mechanism drives the feeding table 200 on which the material bag 201 is placed to rise to a specified height;

[0143] The material blocking mechanism 600 descends, the material blocking pressing plate 620 abuts against the upper surface of the material bag 201, and the material blocking side plate 630 abuts against the side surface of the material bag 201;

[0144] The needle insertion mechanism 300 moves in a direction close to the feed table 200 and is laterally inserted into the middle of the material bag 201 located on the feed table 200;

[0145] The material blocking mechanism 600 rises, the material blocking pressing plate 620 is separated from the upper surface of the material bag 201, and the material blocking side plate 630 is separated from the side surface of the material bag 201;

[0146] The pin insertion mechanism 300 moves in a direction away from the feed table 200, and transports the material bag 201 to the dust removal mechanism 400. The upper dust removal component 410 and the lower dust removal component 420 of the dust removal mechanism 400 absorb dust on the upper surface and the lower surface of the material bag 201 respectively.

[0147] The pin insertion mechanism 300 continues to move in a direction away from the feed table 200, and conveys the material bag 201 to the cutting mechanism 500. The cutting mechanism 500 cuts a discharge port on the lower surface of the material bag 201, so that the material in the material bag 201 falls into the discharge bin 110;

[0148] The pin insertion mechanism 300 continues to move in a direction away from the feed table 200, and conveys the material bag 201 to the flapping mechanism 700. The flapping mechanism 700 flaps the material bag 201, so that the remaining material in the material bag 201 falls from the discharge port into the drop bin 110;

[0149] The needle insertion mechanism 300 continues to move in a direction away from the feed table 200, and conveys the material bag 201 to the bag-returning mechanism 800. The bag-returning mechanism 800 blocks the material bag 201 from moving with the needle insertion mechanism 300, so that the material bag 201 falls off the needle insertion mechanism 300.

[0150] Repeat the above steps.

[0151] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
