[0064] This invention discloses a flipping and unloading device that enables automatic unloading, thereby reducing manual labor intensity and improving production efficiency. This invention also discloses an automatic bag-cutting and unloading system.

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] Please refer to the attached document. Figure 6 - Appendix Figure 11 .

[0067] The tilting and unloading device of the present invention includes a unloading frame 91, a unloading lifting component 92, and a tilting component 93.

[0068] The flipping assembly 93 includes a flipping plate 9301, a flipping shaft 9303, a drive assembly 9311, and a mounting bracket. The flipping plate 9301 can releasably fix the material. Specifically, a fixing member for releasably fixing the material is provided on the flipping plate 9301. The fixing member can be a retractable push plate provided on the flipping plate 9301, with multiple push plates arranged around the center of the flipping plate 9301. When the multiple push plates converge toward the center of the flipping plate 9301, they clamp the material; when the multiple push plates disperse toward the periphery of the flipping plate 9301, they release the material. The fixing member can also be an adsorption assembly provided on the back of the flipping plate 9301. The flipping plate 9301 has ventilation holes, and the material on the flipping plate 9301 is sucked up by the suction force of the adsorption assembly.

[0069] In another specific embodiment of the present invention, a material discharge hopper device 94 is provided on the tilting plate 9301. The material discharge hopper device 94 is used to receive materials and to releasably fix the materials. The working principle of the material discharge hopper device 94 will be described in detail below.

[0070] A tilting shaft 9303 is connected to the edge of one side of the tilting plate 9301, and both ends of the tilting shaft 9303 are hinged to the mounting bracket. A drive assembly 9311 is fixedly connected to the mounting bracket, and the output shaft of the drive assembly 9311 is connected to the tilting shaft 9303. The drive assembly 9311 is used to drive the tilting shaft 9303 to rotate. When the drive assembly 9311 drives the tilting shaft 9303 to rotate in one direction, the tilting plate 9301 tilts and dumps material. When the drive assembly 9311 drives the tilting shaft 9303 in another direction, the tilting plate 9301 returns to its original position.

[0071] The material pouring and lifting assembly 92 is mounted on the material pouring frame 91. The output end of the material pouring and lifting assembly 92 is connected to the mounting frame, and the material pouring and lifting assembly 92 drives the mounting frame to rise or fall. In other words, the material pouring and lifting assembly 92 drives the tilting assembly 3 to rise or fall.

[0072] In this invention, the material is first fixed onto the tilting plate 9301 by a push plate or adsorption component. Then, the tilting component 93 is driven to rise to a preset position by the material discharge lifting component 92. Next, the driving component 9311 drives the tilting shaft 9303 to rotate in one direction, causing the tilting plate 9301 to tilt. After the tilting plate 9301 tilts to a preset angle, the push plate or adsorption component on the tilting plate 9301 releases the material, which then automatically falls into a designated device under gravity. The driving component 9311 then drives the tilting shaft 9303 in the opposite direction to reset the tilting plate 9301. Finally, the material discharge lifting component 92 drives the tilting component 93 to descend and reset, receiving the material to begin the next tilting and discharging cycle.

[0073] A material sensor 9314 is installed on the tilting plate 9301. This material sensor 9314 is used to detect whether there is material on the tilting plate 9301. The material sensor 9314 can be a photoelectric sensor or a pressure sensor. If the material sensor 9314 detects that there is material on the tilting plate 9301, it will trigger the controller to send a control signal to the unloading lifting assembly 92, so that the unloading lifting assembly 92 outputs an upward displacement, thereby driving the tilting assembly 93 to rise to a preset position to unload the material.

[0074] To facilitate the installation of the material sensor 9314, the present invention provides a hollow structure on the flip plate 9301, and a mounting protrusion 9313 is provided within the hollow structure, on which the material sensor 9314 is mounted. This hollow structure provides operating space for the installation of the material sensor 9314 and reduces the weight of the flip plate 9301.

[0075] The mounting frame in this invention specifically includes a first upright plate 9306 and a second upright plate 9307. A bearing 9304 is respectively provided on the inner side of the first upright plate 9306 and the inner side of the second upright plate 9307. Both ends of the tilting shaft 9303 are respectively mounted in the two bearings 9304, meaning the tilting shaft 9303 is hinged to the mounting frame through the two bearings 9304. Furthermore, this invention preferably uses self-aligning ball bearings for the bearings 9304. Self-aligning ball bearings have self-aligning properties, which can compensate for the deflection error of the tilting shaft 9303, thereby improving the stability of the tilting plate 9301 during tilting.

[0076] The drive assembly 9311 specifically includes a motor 93110 and a reducer 93111. Both the motor 93110 and the reducer 93111 are mounted on the outer side of the second upright plate 9307 of the mounting bracket. The output shaft of the motor 93110 is connected to the input shaft of the reducer 93111, and the output shaft of the reducer 93111 is connected to the tilting shaft 9303. The housing of the motor 93110 is fixedly connected to the housing of the reducer 93111, and the housing of the reducer 93111 is connected to the cantilever shaft 9315 of the second upright plate 9307 via a torque arm 9316. The fixed end of the cantilever shaft 9315 is fixedly connected to the second upright plate 9307, and the cantilever shaft 9315 extends away from the second upright plate 9307 to maintain a safe distance between the reducer 93111 and the motor 93110 and the second upright plate 9307.

[0077] The flip plate 9301 in this invention specifically includes a main flip plate 93011 and two side flip plates 93012. There are two side flip plates 93012, located on opposite sides of the main flip plate 93011. On the side near the flip axis 9303, the side flip plate 93012 protrudes relative to the main flip plate 93011 towards the flip axis 9303, forming a pivot connection portion 9302. The flip axis 9303 passes sequentially through the pivot connection portions 9302 on both side flip plates 93012, and is fixedly connected to the side flip plates 93012. In this invention, the flip axis 9303 only needs to be assembled with the pivot connection portions 9302 of the two side flip plates 93012, without needing to be assembled with the main flip plate 93011, thus significantly reducing the assembly difficulty of the flip plate 9301 and the flip axis 9303.

[0078] It should be noted that the flip shaft 9303 and the rotating shaft connection part 9302 can be fixedly connected by a shaft shoulder and a spring pin.

[0079] In addition, in order to reduce the weight of the flip plate 9301, the present invention also provides a load reduction hole on the flip main board 93011.

[0080] The mounting bracket of this invention includes a first upright plate 9306 and a second upright plate 9307, as well as a first bottom plate connecting plate 9310 and a first top connecting plate 9312. The first bottom plate connecting plate 9310 is located below the first upright plate 9306 and the second upright plate 9307, and is used to connect the first upright plate 9306 and the second upright plate 9307. The first top connecting plate 9312, the first upright plate 9306, the second upright plate 9307, and the first bottom plate connecting plate 9310 form a closed frame, thereby improving the structural strength and overall integrity of the mounting bracket.

[0081] It should be noted that, in order to further enhance the structural strength of the mounting bracket, the present invention also provides reinforcing ribs 9305 at the connection points of the first upright plate 9306 and the first bottom plate connecting plate 9310, the connection points of the first upright plate 9306 and the first top connecting plate 9312, the connection points of the second upright plate 9307 and the first bottom plate connecting plate 9310, and the connection points of the second upright plate 9307 and the first top connecting plate 9312.

[0082] The material handling and lifting assembly 92 of this invention specifically includes a fixedly arranged slide rail module 922 and a lead screw module 921. The slide rail module 922 and the lead screw module 921 are arranged opposite to each other and spaced apart. The gap between the slide rail module 922 and the lead screw module 921 is used to accommodate the tilting assembly 93.

[0083] The slide rail module 922 includes a slide rail 9221 and a driven slider 9222. The driven slider 9222 is slidably engaged with the slide rail 9221, meaning it can slide up and down along the slide rail 9221. The lead screw module 921 includes a lifting nut 9212, which can rise or fall. The mounting bracket of the tilting assembly 93 is connected to the lifting nut 9212 and the driven slider 9222 on both sides, respectively. Driven by the lifting nut 9212, the tilting assembly 93 moves up and down along the slide rail 9221.

[0084] To facilitate the connection between the mounting bracket and the driven slider 9222 and the lifting nut 9212, the present invention provides a slider connecting plate 9223 on the driven slider 9222 and a nut connecting plate 9210 on the lifting nut 9212. The mounting bracket is connected to the driven slider 9222 via the slider connecting plate 9223 and to the lifting nut 9212 via the nut connecting plate 9210.

[0085] To prevent wear and tear on wiring or conduits during the lifting and lowering of the tilting assembly 93, this invention also includes a tank chain assembly 923. The tank chain assembly 923 is located next to the lead screw module 921. The tank chain assembly 923 includes a tank chain 9230 and a tank chain mounting plate 9231. During the lifting and lowering of the tilting assembly 93, the wiring and conduits follow the path of the tank chain 9230, thereby preventing wear and tear due to pressure buildup on the wiring or conduits.

[0086] To facilitate the connection between the mounting bracket and the driven slider 9222, a third upright plate 9308 is added. The upper end of the third upright plate 9308 is connected to the second upright plate 9307 via a second top connecting plate 9309, and the lower end of the third upright plate 9308 is connected to the second upright plate 9307 via a second bottom connecting plate 9317. That is, the third upright plate 9308, the second top connecting plate 9309, the second bottom connecting plate 9317, and the second upright plate 9307 form a closed frame, thereby improving the structural strength of the mounting bracket. The first top connecting plate 9312 and the second top connecting plate 9309 can be a single integral plate.

[0087] The third upright plate 9308 and the first upright plate 9306 are the two sides of the mounting bracket. The first upright plate 9306 is connected to the lifting nut 9212, and the third upright plate 9308 is connected to the driven slider 9222.

[0088] It should be noted that the third upright plate 9308 is located above the drive assembly 9311, and the third upright plate 9308 is farther away from the second upright plate 9307 relative to the drive assembly 9311, or it can be understood that the third upright plate 9308 protrudes outward relative to the drive assembly 9311. The third upright plate 9308 is connected to the lifting nut 9212 of the lead screw module 921, and there is a certain distance between the drive assembly 9311 and the lead screw module 921, which can effectively prevent friction and collision between the drive assembly 9311 and the lead screw module 921.

[0089] The tilting and unloading device 9 of this invention includes a top plate 91, a bottom plate 913, a back plate, and two side plates 912. That is, the tilting and unloading frame 91 is a cuboid structure with an opening on one side. A space is formed between the two side plates 912 to accommodate the tilting assembly 93 and the unloading lifting assembly 92. The slide rail module 922 and the lead screw module 921 are respectively mounted on the two side plates 912 of the tilting and unloading frame 91. The arrangement of the tilting and unloading frame 91 makes the tilting and unloading device 9 a single unit, facilitating movable layout.

[0090] The slide rail module 922 includes a slide rail mounting plate 9220, which is fixedly connected to one side plate 912 of the unloading machine frame 91. The lead screw module 921 includes a lead screw mounting plate 9211, which is fixedly connected to the other side plate 912 of the unloading machine frame 91.

[0091] This invention also discloses an automatic bag-cutting and material-discharging system; please refer to the appendix. Figure 1 The system includes a conveyor belt 1 for conveying bagged material (bagged material being a specific form of material), and a vacuum breaking device 5, a bag cutting device 8, and a turning and unloading device 9 are sequentially arranged along the conveying direction of the conveyor belt 1. The vacuum breaking device 5 conveys the bagged material to the bag cutting device 8 through the conveyor belt 1. The bag cutting device 8 can convey the bagged material to the turning and unloading device 9.

[0092] The vacuum breaking device 5 includes a bag gripping assembly and a needle assembly 53. The bag gripping assembly is used to grip the bag material on the mesh belt 1 and is vertically movable. The needle assembly 53 includes needles 531, which are retractable and used to puncture the bag material gripped by the bag gripping assembly. As the bag material moves below the bag gripping assembly along with the mesh belt 1, the bag gripping assembly descends to grip the bag material, and then rises with the bag material to a preset position. Afterward, the needles 531 of the needle assembly 53 extend to puncture the bag material, thus completing the vacuum breaking process.

[0093] The bag-cutting device 8 includes a bag-lifting device 83 and a cutter assembly 8200. The bag-lifting device 83 is used to lift the bag material on the mesh belt 1. The bag-lifting device 83 is vertical and can move along the conveying direction of the mesh belt 1. The cutter assembly 8200 includes a cutter 8218, which is movable to cut the bag material. When the bag material moves along the mesh belt 1 to below the bag-lifting device 83, the bag-lifting device 83 lowers to lift the bag material, and then moves the bag material above the tilting plate 9301. The cutter 8218 then extends and moves along the width direction of the bag material to complete the cutting. The cut bag material falls onto the tilting plate 9301.

[0094] The tipping and unloading device 9 includes a tipping and lifting assembly 92 and a tipping assembly 93. The tipping and lifting assembly 92 is used to drive the tipping assembly 93 to lift and lower. The tipping assembly 93 includes a tipping plate 9301, which is rotatable and can receive bag material falling after being cut by the cutter 8218. The tipping plate 9301 can also release and fix the bag material.

[0095] After the bag material falls onto the tilting plate 9301, the tilting plate 9301 fixes the bag material using a push plate or suction component. Then, the material discharge lifting component 92 drives the tilting component 93 to rise to a preset height. The tilting plate 9301 then tilts, and after reaching a preset tilt angle, the push plate or suction component releases the bag material, which falls into the designated equipment under its own weight.

[0096] In this invention, the conveyor belt 1 conveys the bag material, the vacuum breaking device 5 breaks the vacuum in the bag material, the bag cutting device 8 cuts the opening in the bag material, and the tipping and unloading device 9 dumps the inner material from the bag material. Thus, this invention automates the vacuum breaking, bag cutting, and tipping and unloading operations, thereby greatly reducing manual labor intensity and improving production efficiency.

[0097] Please refer to the attached document. Figure 1 and attached Figure 22 In this invention, a movable hopper device 10 is provided downstream of the tilting and unloading device 9. The movable hopper device 10 is used to receive and transport the material poured out by the tilting and unloading device 9. The movable hopper device 10 includes a movable hopper 101 and a movable hopper support 102, with the movable hopper 101 mounted on the movable hopper support 102. Furthermore, the bottom of the movable hopper support 102 is provided with movable rollers to facilitate the movement of the movable hopper device 10.

[0098] Please refer to the attached document. Figure 1 and attached Figure 20Along the conveying direction of the mesh belt 1, a lower brush device 6 and an upper brush device 7 are sequentially arranged between the vacuum breaking device 5 and the bag cutting device 8. The lower brush device 6 and the upper brush device 7 are arranged alternately or adjacently. The lower brush device 6 includes a lower brush 61 and a lower brush support 62. The lower brush 61 is mounted on the lower brush support 62, which is mounted on the wire frame 11 of the mesh belt 1, with the lower brush 61 facing upwards. If the bag opening is bent downwards, the bag opening will unfold under the friction of the lower brush 61 as the bag passes through it.

[0099] The upper brush device 7 includes an upper brush 71 and an upper brush support 72. The upper brush 71 is mounted on the upper brush support 72, which is mounted on the wire frame 11 of the mesh belt 1. The upper brush 71 faces downwards, and a space is formed below the upper brush 71 for the bag material to pass through. If the bag opening is bent upwards, the bent opening will unfold under the friction of the upper brush 71 when the bag material passes through it. It should be noted that the bag opening can only be lifted by the bag lifting device 83 when it is in an unfolded state, or in a non-bent state, thus facilitating the bag cutting device 8 to perform the bag cutting operation.

[0100] In addition, an air shower device 4 is provided upstream of the vacuum breaking device 5. The air shower device 4 includes an air shower shell and a blowing device installed inside the air shower shell. The blowing device is used to blow air onto the bag material passing through the air shower shell.

[0101] Please refer to the attached document. Figure 1 and attached Figure 21 A spray device 2 is installed upstream of the air shower device 4. The spray device 2 includes a left spray head group 21 and a right spray head group 22, which are respectively located on both sides of the mesh belt 1. The spray device 2 also includes a spray sensor 23. When the spray sensor 23 detects bagged material on the mesh belt 1, the spray sensor 23 controls the left spray head group 21 and the right spray head group 22 to spray alcohol onto the bagged material. The bagged material after being sprayed will then enter the air shower device 4.

[0102] The conveyor belt 1 includes a first conveyor belt, a second conveyor belt, and a turning conveyor 3. The first and second conveyor belts are arranged perpendicularly and connected by the turning conveyor 3. The first conveyor belt passes through a spray device 2, and the second conveyor belt passes sequentially through an air shower device 4, a vacuum breaking device 5, a lower brush device 6, and an upper brush device 7, ultimately conveying the bag material to a bag cutting device 8. When the bag material moves on the first conveyor belt, its width direction is aligned with the conveying direction. After passing through the turning conveyor 3, the length direction of the bag material is aligned with the conveying direction, preparing for the subsequent bag lifting step of the bag lifting device 83.

[0103] Please refer to the attached document. Figure 2 - Appendix Figure 5 .

[0104] The vacuum breaking device 5 also includes a vacuum breaking frame 51 and a vacuum breaking lifting assembly 52. ​​The vacuum breaking lifting assembly 52 is mounted on the vacuum breaking frame 51, with its piston facing downwards, and the bag gripping assembly is connected to the piston. The piercing needle assembly 53 is located on the side of the vacuum breaking frame 51. After the bag material on the mesh belt 1 is gripped by the bag gripping assembly and rises with the piston of the vacuum breaking lifting assembly 52, the piercing needle 531 extends and pierces the bag material.

[0105] The vacuum breaking lifting assembly 52 of this invention includes a lifting cylinder 521. The vacuum breaking frame 51 includes a top mounting plate 511, and the lifting cylinder 521 is mounted on the top mounting plate 511 of the vacuum breaking frame 51.

[0106] In this invention, the vacuum-breaking device 5 can grip the bag material using an adsorption method. Specifically, the bag-gripping assembly can be a suction cup assembly 56. The suction cup assembly 56 includes a suction cup 562 and a suction cup connecting plate 561. The suction cup 562 is connected to the suction cup connecting plate 561. The piston end of the lifting cylinder 521 is connected to a piston connecting plate 522, and the suction cup connecting plate 561 and the piston connecting plate 522 are interconnected, thus achieving the connection between the piston of the vacuum-breaking lifting cylinder 521 and the suction cup 562. The suction cup 562 is used to adsorb the bag material. Gripping the bag material using adsorption avoids damage to the bag material.

[0107] The limiting assembly 54 includes a linear bearing 543, a lifting shaft 541, and a limiting ring 542. The bottom of the lifting shaft 541 is connected to the suction cup connecting plate 561. The linear bearing 543 is fixedly connected to the top mounting plate 511 of the vacuum breaking frame 51. The lifting shaft 541 is clearance-fitted into the linear bearing 543. The diameter of the limiting ring 542 is larger than the inner diameter of the linear bearing 543. During the process of the lifting cylinder 521 driving the suction cup assembly 56 to descend, if the limiting ring 542 touches the upper end of the linear bearing 541, the lifting cylinder 521 cannot continue to move downward. This ensures that the suction cup assembly 56 descends to the preset position to facilitate the adsorption of the bag material below.

[0108] Furthermore, the limiting ring 542 in this invention is detachably connected to the lifting shaft 541, and the height of the limiting ring 542 can be adjusted according to the specific size of the bag material to ensure that the suction cup assembly 56 descends to the appropriate position. This improves the flexibility of the vacuum breaking device 5.

[0109] The limit ring 542 can be detachably connected to the lifting shaft 541 by bolts.

[0110] It should be noted that the lifting shaft 541 is fitted inside the linear bearing 543. Since the inner ring of the linear bearing 543 is rotatable relative to the outer ring, this greatly reduces the friction between the lifting shaft 541 and the inner ring of the linear bearing 543. A flange is provided at the bottom of the linear bearing 543, and the linear bearing 543 is fixed to the top mounting plate 511 of the vacuum breaking frame 51 via the flange. Bolt holes are provided on the flange, and bolts that mate with these bolt holes are screwed into the top mounting plate 511, thereby locking the flange to the back of the top mounting plate 511. The linear bearing 543 passes through the top mounting plate 511 and extends upward from the top mounting plate 511. Based on balance and limiting considerations, this invention provides multiple limiting components 54, which are evenly distributed around the lifting cylinder 521. In one specific embodiment of the invention, four limiting components 54 are provided, and the four limiting components 54 are evenly distributed around the lifting cylinder 521.

[0111] The present invention also provides an electromagnetic valve assembly 57 on the top mounting plate 511 of the vacuum breaking frame 51. The electromagnetic valve assembly 57 is communicatively connected to the lifting cylinder 521, the suction cup assembly 56 and the needle cylinder 535 to form an automated control of the lifting cylinder 521, the suction cup assembly 56 and the needle cylinder 535.

[0112] The needle assembly 53 specifically includes a needle cylinder 535 and a needle 531. The retractability of the needle 531 is achieved through the retraction of the needle cylinder 535. Those skilled in the art will understand that a lead screw or gear assembly can be used instead of the needle cylinder 535, and this document does not specifically limit the components that drive the retraction of the needle 531.

[0113] In addition to the needle 531 and the needle cylinder 535, the needle assembly 53 also includes a needle mounting plate and a cylinder mounting plate. The needle cylinder 535 is mounted on the side of the top mounting plate 511 of the vacuum breaking frame 51 via the cylinder mounting plate. The needle mounting plate is used to mount the needle 531. The needle mounting plate is connected to the piston of the needle cylinder 535. Multiple needles 531 are arranged side by side.

[0114] Specifically, the needle mounting plate may include a needle clamping plate 532 and an intermediate connecting plate 534. The needle clamping plate 532 is used to clamp the needle 531. The intermediate connecting plate 534 is connected to the needle clamping plate 532 and also to the piston of the needle cylinder 535.

[0115] For structural stability considerations, the present invention may provide angular reinforcing ribs 533 between the intermediate connecting plate 534 and the needle clamping plate 532 to improve the firmness of the connection between the intermediate connecting plate 534 and the needle clamping plate 532.

[0116] The cylinder mounting plate includes a flat plate 536 that fits onto and connects to the needle cylinder 535, and a vertical plate 537 connected to the flat plate 536. The vertical plate 537 has bolt holes, which are oblong holes, for connection to the top mounting plate 511 of the vacuum breaking frame 51. Thus, the height of the needle assembly 53 can be adjusted by vertically adjusting the vertical plate 537 to ensure that the needle assembly 53 adapts to different working conditions. After the vertical plate 537 is adjusted to the correct position, the bolts are screwed into the oblong holes to lock the vertical plate 537 onto the top mounting plate 511 of the vacuum breaking frame 51.

[0117] Furthermore, the waist-shaped hole is set to two holes on the left and right to improve the balance and firmness of the connection between the cylinder connecting plate and the top mounting plate 511 of the vacuum breaking frame 51.

[0118] To improve the stability of the connection between the vertical plate 537 and the flat plate 536, a reinforcing rib 538 can be provided between the vertical plate 537 and the flat plate 536.

[0119] To protect the vacuum breaking lifting assembly 52, the lifting shaft 541, and the solenoid valve assembly 57, the present invention can also provide a protective cover 55 on the top mounting plate 511 of the vacuum breaking frame 51. Furthermore, the protective cover 55 is transparent to facilitate observation.

[0120] In addition to a top mounting plate 511, the vacuum breaking frame 51 includes support legs 512 for supporting the top mounting plate 511. Foot cups 513 are mounted on the bottom of the support legs 512. A conveyor line passes between the support legs 512.

[0121] Please refer to the attached document. Figure 12 and attached Figure 13 .

[0122] As described above regarding the tipping and unloading device 9, the tipping and unloading device 9 can also receive bagged material and releasably secure the bagged material via a unloading hopper device 94 mounted on the tipping plate 9301. The unloading hopper device 94 will now be described in detail. The unloading hopper device 94 of this invention includes an unloading hopper 941, which receives the cut bagged material. The bottom of the unloading hopper 941 has screw holes for connection to the tipping plate 9301. A push plate 942 is disposed inside the unloading hopper 941, and the push plate 942 is movably connected to the hopper wall of the unloading hopper 941. A drive unit for driving the push plate 942 is also provided on the hopper wall of the unloading hopper 941, and the output end of the drive unit is connected to the push plate 942. Multiple push plates 942 are evenly distributed along the circumference of the unloading hopper 941. Driven by the drive unit, multiple push plates 942 either converge toward the center of the discharge hopper 941 or disperse toward the periphery of the discharge hopper 941.

[0123] After the bagged material falls into the discharge hopper 941, the drive unit drives multiple push plates 942 to converge towards the center of the discharge hopper 941, clamping the bagged material inside. Then, the tilting plate 9301 drives the discharge hopper 941 to tilt. After the tilting plate 9301 tilts to a preset tilt angle, the drive unit drives multiple push plates 942 to disperse around the discharge hopper 941, releasing the clamping of the bagged material. Then, the material inside the bag can fall down along the tilted discharge hopper 941 into the designated equipment under its own gravity.

[0124] The present invention effectively controls the bag material through the drive unit and push plate 942, which can prevent the bag material from falling arbitrarily during the flipping process and ensure that the inner material in the bag falls into the designated equipment according to the preset target, thereby improving the operation quality and efficiency of the flipping and unloading device.

[0125] When multiple push plates 942 converge toward the center of the material hopper 941, they can form a closed structure, enclosing the bagged material within the closed structure. This effectively prevents the material from entering the back of the push plate 942 or being stuck by it when the tilting plate 9301 tilts to a preset angle and the material falls, thus further improving the operational quality of the automated tilting and unloading equipment.

[0126] It should be noted that by taking into account the volume of the bag material and the stroke of the pusher plate 942 in the actual processing, the size of the pusher plate 942 can be designed so that multiple pushers 942 can be formed into a closed structure.

[0127] In this invention, the driving unit is preferably a cylinder 943, which has high operating precision. Each cylinder 943 is used to drive one pusher plate 942.

[0128] The cylinder 943 is specifically configured as follows: The cylinder 943 is located on the outer side of the hopper wall of the discharge hopper 941. The piston of the cylinder 943 penetrates the hopper wall of the discharge hopper 941 to connect with the corresponding push plate 942. Specifically, the cylinder 943 is connected to the hopper wall via a fixing plate assembly. The fixing plate assembly includes an angle plate 9441 and a support plate 9442. A portion of the angle plate 9441 is attached to and fixed to the hopper wall of the discharge hopper 941, and another portion is attached to and fixed to the upper surface of the cylinder 943. Thus, the connection between the cylinder 943 and the discharge hopper 941 is achieved through the angle plate 9441. To ensure the structural strength of the angle plate 9441, the angle plate 9441 in this invention also includes a reinforcing plate. One side of the reinforcing plate is connected to a portion of the angle plate 9441, and the other side of the reinforcing plate is connected to another portion of the angle plate 9441. The support plate 9442 is located below the cylinder 943 and is used to support the cylinder 943. The support plate 9442 is fastened to the wall of the discharge hopper 941 by bolts.

[0129] The present invention configures the material hopper 941 as a cuboid structure. The material hopper 941 has four hopper walls, and a pusher plate 942 is provided on each hopper wall. When clamping the bag material, the four pusher plates 942 converge to form a frame shape, thereby enclosing the bag material within the frame structure.

[0130] In this invention, the upper part of the push plate 942 extends outside the discharge hopper 941, and the upper part of the push plate 942 has an inclined portion 9421 that slopes outward radially along the discharge hopper 941. Because the upper part of the push plate 942 extends outside the discharge hopper 941, even if the bag material inside the discharge hopper 941 overflows from the opening of the discharge hopper 941, the push plate 942 can still push the bag material. The inclined portion 9421 on the upper part of the push plate 942 forms a flared opening to facilitate the bag material falling into the discharge hopper 941. Furthermore, when the discharge hopper 941 is at a preset tilt angle, the outwardly tilted portion 9421 guides the outflow of material.

[0131] As described above, the control of the bag material in this invention is achieved through the clamping force of the push plate 942. To further enhance the control of the bag material, the invention incorporates the following design: a first suction cup 9451 is provided on the surface of the push plate 942 facing the center of the discharge hopper 941. The suction port of the first suction cup 9451 faces the center of the discharge hopper 941, and two first suction cups 9451 can be arranged side-by-side on each push plate 942. After the cylinder 943 drives the push plate 942 to converge towards the center of the discharge hopper 941 to form a clamping force on the bag material, the first suction cups 9451 are then controlled to form a suction force on the bag material, thereby achieving stable positioning of the bag material.

[0132] In addition to creating suction on the side of the bag material, this invention also includes a second suction cup 9452 to create suction on the bottom of the bag material. The second suction cup 9452 is mounted on the bottom plate 913 inside the discharge hopper 941. The suction port of the second suction cup 9452 faces upward.

[0133] A material sensor 9314 is provided on the tilting plate 9301, which is used to detect whether there is bagged material in the dispensing hopper 941. The present invention provides a through hole 946 on the bottom plate 913 of the dispensing hopper 941, which is directly opposite the material sensor 9314 on the tilting plate 9301. The material sensor 9314 can be a photoelectric sensor or a pressure sensor.

[0134] Please refer to Figure 14-19 .

[0135] The bag-cutting device of the present invention includes:

[0136] Main framework 81,

[0137] The mobile device 82 is installed on the main frame 81 and is equipped with a movable cutter assembly 8200, which is used to cut the bag material.

[0138] The bag-carrying device 83 is used to tension the part of the bag material to be cut. The bag-carrying device 83 is mounted on the moving device 82 in a height-adjustable manner and can be moved by the moving device 82.

[0139] Preferably, the main frame 81 is a frame structure constructed from profiles.

[0140] In the process of using the bag cutting device provided in this specific embodiment, firstly, the moving device 82 needs to drive the bag lifting device 83 to a suitable position and adjust the height of the bag lifting device 83. When the bag material moves to a position that can be tensioned by the bag lifting device 83, the movement of the bag material is stopped. The bag lifting device 83 tensions the bag material and drives the bag material up and down to a position suitable for the cutting blade assembly 8200 to cut it. Since the bag material is lifted by the bag lifting device 83, the part of the bag material to be cut is in a tensioned state. At this time, the cutting blade assembly 8200 moves and can cut the bag material, realizing the automation of the bag cutting process.

[0141] Compared with existing technologies, the bag-cutting device provided in this specific embodiment automates the bag-cutting process, reduces manual labor intensity, improves work efficiency, and enhances safety.

[0142] In one specific embodiment, the moving device 82 includes a rodless cylinder 8211, a slide rail 8202 that is parallel to and spaced apart from the rodless cylinder 8211, and a truss 8205 that is mounted between the slide rail 8202 and the rodless cylinder 8211 and is movable along the slide rail 8202; the cutter assembly 8200 is mounted below the truss 8205.

[0143] like Figure 15As shown, the mobile device 82 includes a mounting base plate 8201, a slide rail 8202, a slide rail connecting block 8203, a truss connecting block 8204, a truss 8205, a truss lifting connecting plate 8206, a mounting frame 8207, a tank chain connecting sheet metal 8208, a cylinder truss connecting plate 8209, a cylinder connecting block 8210, a rodless cylinder 8211, a tank chain 8212, a tank chain fixing sheet metal 8213, and a rodless cylinder mounting plate 8214. Both the rodless cylinder mounting plate 8214 and the mounting base plate 8201 are mounted on the main frame 81. One end of the truss 8205 is provided with a cylinder truss connecting plate 8209, which is connected to the cylinder connecting block 8210. The cylinder connecting block 8210 and the rodless cylinder 8211 move together... The truss 8205 is connected to the poleless flagpole 2811 at one end, which is equipped with a tank chain connecting sheet metal 8208. The poleless cylinder mounting plate 8214 is equipped with a tank chain fixing sheet metal 8213. One end of the tank chain 8212 is connected to the tank chain connecting sheet metal 8208, and the other end is connected to the tank chain fixing sheet metal 8213. The other end of the truss 8205 is slidably connected to the slide rail 8202 via the slide rail connecting block 8203 and the truss connecting block 8204. Under the drive of the poleless cylinder 8211, the truss 8205 can slide along the slide rail 8202. The upper surface of the truss 8205 is equipped with a truss lifting connecting plate 8206. The mounting frame 8207 is installed on the truss lifting connecting plate 8206, and the carrying device 83 is connected to the mounting frame 8207. Figure 15 As shown, the mounting frame 8207 includes two parallel and spaced-apart plate-like structures on the truss lifting connection plate 8206, and the plate-like structures are perpendicular to the truss lifting connection plate 8206.

[0144] In this specific embodiment, the truss 8205 is mounted on the slide rail 8202 and the rodless cylinder 8211, which facilitates its installation on the main frame 81. Furthermore, under the same extension stroke, the rodless cylinder 8211 occupies less space, making the structural layout more reasonable.

[0145] In one specific embodiment, the cutter assembly 8200 includes: a cutter 8218 for cutting through bag material; a lifting power component 8215, one end of which is connected to the truss 8205 and the other end of which is connected to the sliding power component 8216; a sliding power component 821, to which the cutter 8218 is connected to the moving end of the sliding power component 8216, wherein the sliding power component 8216 can drive the cutter 8218 to slide, and the lifting power component 8215 can drive the sliding power component 8216 and the cutter 8218 to rise and fall; and a telescopic power component 8217, installed on the sliding power component 8216 and connected to the cutter 8218, wherein the telescopic power component 8217 drives the cutter 8218 to move, so that the cutter 8218 extends or retracts. The telescopic power component 8217 and the cutter 8218 are mounted to the moving end of the sliding power component 8216 via the mounting plate 8220. The moving end of the sliding power component 8216 is provided with a sliding slider 82161. The mounting plate 8220 is mounted on the slider 82161. The telescopic power component 8217 is fixed to the mounting plate 8220. The cutter 8218 is movably mounted on the mounting plate 8220. The telescopic end of the telescopic power component 8217 is connected to the cutter 8218. By controlling the telescopic extension and retraction of the telescopic power component 8217, the cutter 8218 can be moved on the mounting plate 8220. A mounting sheet metal is fixedly provided on the sliding power component 8216. A cutter sensor 8219 for detecting the position of the cutter 8218 is provided on the mounting sheet metal.

[0146] like Figure 16 , 17 As shown, the lifting power component 8215 consists of two cylinders mounted on the lower surface of the truss 8205. The telescopic ends of the cylinders are connected to connecting plates. The sliding power component 8216 is a rodless cylinder 8211, mounted on the connecting plate at the telescopic end of the lifting power component 8215. The moving end of the rodless cylinder 8211 is connected to a slider 82161, which is connected to a mounting plate 8220. The cutter 8218 is movably mounted on the mounting plate 8220. Specifically, a groove for the cutter 8218 can be provided on the mounting plate 8220, or a sliding groove can be provided. The guide rail allows the cutter 8218 to move along it, the specific movement depending on the actual situation. The telescopic power component 8217 is a slide cylinder, which pushes the cutter 8218 to move on the mounting plate 8220, so that the cutter 8218 extends or retracts. A mounting sheet metal is fixedly installed on the sliding power component 8216. A cutter sensor 8219 for detecting the position of the cutter 8218 is installed on the mounting sheet metal. During use, the cutter sensor 8219 can be used to detect the extension distance of the cutter 8218 in order to determine whether the cutter 8218 has extended to the correct position.

[0147] Preferably, the cutter sensor 8219 is connected to the sliding force member 8216 via sheet metal. The sheet metal is provided with an elongated hole for mounting the cutter sensor 8219, and the mounting position of the cutter sensor 8219 can be adjusted along the elongated hole.

[0148] In the process of using the bag cutting device provided in this specific embodiment, firstly, the rodless cylinder 8211 drives the truss 8205 to move to a suitable position, the lifting power component 8215 drives the cutter 8218 to rise and fall to a suitable height, the telescopic power component 8217 extends the cutter 8218 to a position where it can cut the flexible packaging bag, and the cutter sensor 8219 detects the cutter 8218; the sliding power component 8216 drives the cutter 8218 to move, thereby cutting the flexible packaging bag.

[0149] In one specific embodiment, the bag-carrying device 83 includes: a lifting module 8301, which is installed on the mobile device 82;

[0150] The tensioning component is installed on the lifting module 8301 and is driven to lift by the lifting module 8301; the tensioning component is used to tension the bag material.

[0151] like Figure 18 As shown, the lifting module 8301 includes a servo motor 8311, which is connected to the tensioning component through a transmission component and drives the tensioning component to lift as a whole. The servo motor 8311 is connected to the mounting bracket 8207 set on the truss 8205 through the lifting module connecting plate 8312.

[0152] The tensioning assembly includes: a support plate 8302, which is fixedly installed on the lifting module 8301; a tensioning plate 8303, which can move closer to or further away from the support plate 8302; and a tensioning drive component 8304, which is used to drive the tensioning plate 8303 to rise and fall, so that the tensioning plate 8303 tensions the bag material to the support plate 8302 or releases the bag material; the tensioning drive component 8304 is installed on the lifting module 8301.

[0153] like Figure 19 As shown, the tensioning assembly also includes a drive component mounting plate 8305 for mounting the tensioning drive component 8304. The drive component mounting plate 8305 is provided with a linear bearing 8306, and the tensioning plate 8303 is connected to a cylindrical shaft 8307 that cooperates with the linear bearing 8306. During the process of the tensioning drive component 8304 driving the tensioning plate 8303 to rise and fall, the cylindrical shaft 8307 moves along the linear bearing 8306, which can effectively prevent the tensioning plate 8303 from tilting during the rising and falling process and ensure that the bag material can be tensioned.

[0154] The drive mounting plate 8305 and the support plate 8302 are disposed opposite to each other, and at least one of the drive mounting plate 8305 and the support plate 8302 is provided with a detection sensor for detecting the position of the bag material and a sensor mounting plate 8310 for mounting the detection sensor; the detection sensor can be a through-beam sensor, the transmitter 8308 of the through-beam sensor is mounted on the lower part of the support plate 8302, and the receiver 8309 of the through-beam sensor is mounted on the upper part of the drive mounting plate 8305, and both the drive mounting plate 8305 and the support plate 8302 are provided with through holes for transmitting the signal emitted by the transmitter 8308 to the receiver 8309.

[0155] The operation process of the automatic bag cutting and unloading system in this invention is as follows: The bag material moves along the mesh belt 1 to the spraying device 2, and the spraying device 2 is activated to spray alcohol onto the bag material. Then, the bag material enters the air shower device 4 along the mesh belt 1 to receive air showering. After air showering, the bag material enters the vacuum breaking device 5 along the mesh belt 1.

[0156] At vacuum breaking device 5, the piston of lifting cylinder 521 extends and drives suction cup 562 to approach the bag material. After the limiting ring 542 touches the upper end of linear bearing 543, the piston of lifting cylinder 521 stops descending. Suction cup 562 generates negative pressure to attract the bag material. The piston of lifting cylinder 521 retracts to raise the bag material. After lifting cylinder 521 returns to its initial position, the piston of needle cylinder 535 extends and drives needle 531 to puncture the bag material, thus breaking the vacuum. The piston of needle cylinder 535 retracts. The piston of lifting cylinder 521 extends, driving the bag material to descend. After the limiting ring 542 touches the upper end of linear bearing 543, the piston of lifting cylinder 521 stops descending. Suction cup 562 releases the suction force on the bag material, and the bag material returns to the mesh belt 1.

[0157] The bag material then passes through the lower brush device 6 and the upper brush device 7 in sequence to open the bag opening. The bag material then moves with the mesh belt 1 to the bag cutting device 8.

[0158] At the bag cutting device 8, when the detection sensor located on the drive mounting plate 8305 or support plate 8302 senses the bag opening, the bag material stops moving. The tensioning drive component 8304 drives the tensioning plate 8303 to move downward. The tensioning plate 8303 and the support plate 8302 cooperate to tighten the bag opening. The servo motor 8311 in the lifting module 8301 moves, driving the tensioning component to rise, thereby driving the bag material to rise to a suitable height. At the same time, the rodless cylinder 8211 of the moving device 82 drives the truss 8205 to move into the material unloading hopper device. At this time, the bag material is still in a tensioned state. The slide cylinder in the cutter assembly 8200 drives the cutter 8218 to extend. The sliding force component 8216 drives the extended cutter 8218 to move, completing the bag cutting.

[0159] The cut bag material falls into the lower discharge hopper 941. The cylinder 943 in the discharge hopper device 94 drives the push plate 942 to converge towards the center of the discharge hopper 941, thus surrounding and clamping the bag material. Then, the first suction cup 945 and the second suction cup 9452 are controlled to generate suction to hold the bag material in place.

[0160] Then, the material pouring lifting assembly 92 drives the tilting assembly 93 and the material pouring hopper device 94 to rise to a preset height. Afterwards, the motor 9310 drives the tilting plate 9301 to tilt. Once the tilting plate 9301 tilts to a preset angle, the first suction cup 9451 releases its suction to release the material from the bag. Then, the cylinder 943 controls the push plate 942 to spread outwards around the material pouring hopper 941 to release the clamping force on the bag. The material inside the bag then slides out of the tilted material pouring hopper 941 under its own weight and falls into the hopper device 10. Finally, the material pouring hopper 941 returns to its original position as the tilting plate 9301 descends, receiving the bag material and preparing for the next tilting and pouring cycle.
