[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention realizes fast and accurate clamping and flipping of material boxes through precise controller instructions. In this process, the swing of the clamping jaws, the rotation of the flipping assembly and the start and stop of the motor are all automatically controlled, which greatly reduces the manual operation links and improves the speed and efficiency of material processing. At the same time, the material dumping action after the material box is flipped into place is rapid and thorough, ensuring that the material can completely fall into the receiving area, avoiding material waste and repeated processing, and further improving production efficiency. Through automation and mechanization, the entire process of the material box from the conveyor line to the dumping machine is seamlessly connected. Workers only need to monitor the operating status of the equipment without heavy physical labor, thereby reducing labor intensity and improving work comfort and safety.

[0015] 2. The present invention increases stability during use by providing clamping claws and clamping bosses that are compatible with the clamping grooves of the material box.

[0016] 3. The present invention adopts a flip axis with a gravity-offset rotating structure, which can occupy a smaller space in spatial layout, making the structure simpler and more compact. At the same time, the overall driving part uses a reduction motor and a chain drive, and the clamping power uses an electric cylinder drive, combined with a mechanical limit control structure, which has a simple structure, reliable operation, and convenient maintenance.

[0017] 4. In the present invention, while the clamping electric cylinder starts to fix the material box, the synchronous gear and the synchronous rack are cleverly driven to move through the gear transmission system. This design not only realizes the stable clamping of the material box, but also cleverly triggers the starting mechanism of the suction machine, providing a solution for dust and material adsorption in the subsequent material dumping process. This design not only improves the automation degree of the equipment, but also ensures the continuity and efficiency of the operation; Through the setting of the suction machine, when dumping materials, the dust generated during the dumping process can be effectively adsorbed and collected. This function is essential for maintaining the cleanliness of the production environment and the health of employees. Through the operation of the suction machine, the dust is quickly adsorbed and concentrated in the collection box, which is convenient for subsequent unified cleaning. In addition, when the dumped material is powder, by opening the connecting pipe and the discharge pipe and closing the collection box, the suction machine can absorb the powder scattered during dumping, and transport it to another suction machine and discharge it through the discharge pipe. This design not only reduces the waste of powder, but also improves the utilization rate of materials. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] For example, see Figure 1-11 , an embracing material box unloading machine, comprising a frame 1 and a controller installed in the frame 1, a driving component 2 and a flip component 3 are installed on the frame 1, the output end of the driving component 2 is fixed to the flip component 3, a material box 5 is arranged in the flip component 3, a clamping component for fixing the material box 5 is arranged on the flip component 3, and a clamping control component 4 for driving the clamping component is also arranged in the flip component 3, a photoelectric switch 11 and a reflector 12 are also installed on the end of the frame 1 away from the flip component 3, the photoelectric switch 11 and the reflector 12 are respectively installed on both sides of the frame 1, and a limit switch 13 is also installed in the frame 1; When in use, firstly, the material box 5 filled with materials is conveyed from the full material conveying line to the unloading machine through the conveyor. When the material box 5 enters the frame 1, the photoelectric switch 11 and the reflector 12 are used to detect whether the material box 5 has completely entered. When there is no material box 5 between the reflector 12 and the emitter in the photoelectric switch 11 (the photoelectric switch 11 is mainly composed of a transmitter, a receiver and a detection circuit, which is equivalent to a photoelectric sensor), the emitted infrared light will be reflected back by the reflector 12. At this time, the light signal intensity received by the receiver in the photoelectric switch 11 is relatively strong (on the contrary, when the material box 5 enters, the material box 5 will block the light). The reflector 12 is held, causing the intensity of the light signal received by the receiver in the photoelectric switch 11 to weaken), that is, when the light signal is strong, the detection circuit in the photoelectric switch 11 converts the light signal received by the receiver into an electrical signal (such as a change in voltage or current), or a digital signal (such as a change in high and low levels). After the controller receives the signal output by the photoelectric switch 11, the controller controls the clamping control component 4 to start, and drives the clamping component to run through the clamping control component 4 to fix the material box 5. After fixing, the driving component 2 is started to drive the flipping component 3 to flip, thereby driving the material box 5 to flip and unload the material.

[0023] For example 2, please refer to Figure 1-11The driving assembly 2 includes a driving motor 21, which is fixedly connected to the frame 1. The output end of the driving motor 21 is fixedly connected to the first transmission sprocket 22 through a coupling. A second transmission sprocket 23 is arranged above the first transmission sprocket 22, and the output end of the second transmission sprocket 23 is fixed to the flip assembly 3 through a connecting shaft. A transmission chain 24 is arranged between the first transmission sprocket 22 and the second transmission sprocket 23. The first transmission sprocket 22 and the second transmission sprocket 23 are connected in transmission through the transmission chain 24. The flip assembly 3 includes a flip shaft 31, which is rotatably connected to one end of the frame 1. Two guide rods 32 are fixedly connected to the shaft 31, and two limit rods 36 are also installed on the flip shaft 31, and the two limit rods 36 are respectively arranged below the adjacent guide rods 32. The clamping control component 4 includes a clamping electric cylinder 41, and the clamping electric cylinder 41 is fixedly connected to the flip shaft 31. The output end of the clamping electric cylinder 41 is fixedly connected to a main linkage plate 42, and one end of the main linkage plate 42 is fixedly connected to a driving gear 43, and the driving gear 43 is rotatably connected to the flip shaft 31. The flip shaft 31 is also rotatably connected to a first transition gear 44 and a second transition gear 45, and the first transition gear 44 is meshed with the driving gear 43. , and the first transition gear 44 is meshed with the second transition gear 45, a driven gear 46 is also rotatably connected to the flip shaft 31, and the driven gear 46 is meshed with the second transition gear 45, and a driven link plate 47 is fixedly connected to the driven gear 46, and the ends of the main linkage plate 42 and the driven link plate 47 away from the flip shaft 31 are fixed to the clamping assembly, and the clamping assembly includes a first clamping jaw 33 and a second clamping jaw 34, and the end of the first clamping jaw 33 close to the flip shaft 31 is fixed to the main linkage plate 42, and the end of the second clamping jaw 34 close to the flip shaft 31 is fixed to the driven link plate 47, and the first clamping jaw 33 and the second clamping jaw 34 are fixed to each other. A plurality of clamping bosses 35 for fixing with the material box 5 are installed on the upper surface, a plurality of clamping grooves 51 are opened on the side wall of the material box 5 near the bottom end, and the plurality of clamping bosses 35 are slidably engaged in the adjacent clamping grooves 51, and a clamping position detection switch 38a and a flipping position detection switch 38b are installed at both ends of the flip shaft 31, respectively, a sensing sheet 37 is installed on the side of the second transmission sprocket 23 near the flip shaft 31, and a sensing block 39 is installed on the side of the main linkage plate 42 near the flip shaft 31, the sensing sheet 37 matches the flipping position detection switch 38b, and the sensing block 39 matches the clamping position detection switch 38a; When the material box 5 is fully entered, the controller starts the clamping electric cylinder 41, and the output end of the clamping electric cylinder 41 drives the main linkage plate 42 to swing, so that the main linkage plate 42 drives the first clamping jaw 33 to move in the direction close to the material box 5. When the main linkage plate 42 swings, it drives the driving gear 43 to rotate at the same time, and the driven gear 46 rotates synchronously through the transmission of the first transition gear 44 and the second transition gear 45, so that the driven gear 46 drives the driven link plate 47 to swing, and then the second clamping jaw 34 moves in the direction close to the material box 5 at the same time, until the clamping bosses 35 on the first clamping jaw 33 and the second clamping jaw 34 are clamped on the clamping groove 51 of the material box 5, so as to fix the material box 5; When the first clamping jaw 33 moves, the main linkage plate 42 drives the induction block 39 to rotate accordingly. When the induction block 39 detects a signal from the clamping position detection switch 38a on the flip shaft 31, it is considered that the first clamping jaw 33 and the second clamping jaw 34 have been clamped in place. At this time, the clamping bosses 35 on the first clamping jaw 33 and the second clamping jaw 34 are just engaged with the clamping grooves 51 on the material box 5, thereby completing the fixing of the material box 5. After being fixed, the controller controls the driving motor 21 to start, the driving motor 21 drives the first transmission sprocket 22 to rotate, the first transmission sprocket 22 drives the second transmission sprocket 23 to rotate through the transmission chain 24, so that the flip shaft 31 flips, and the material in the material box 5 falls. When the induction sheet 37 installed on the second transmission sprocket 23 detects a signal by the flip position detection switch 38b, it is considered that the material box 5 has been flipped in place, and the driving motor 21 turns off the flip shaft 31 to stop flipping. At this time, the material is in a completely dumped state, and all the material is poured into the material receiving area; After the dumping action is completed, the controller instructs the drive motor 21 to reverse, so that the flip shaft 31 rotates in the opposite direction. When the limit rod 36 contacts the limit switch 13, the drive motor 21 stops rotating. At this time, the empty material box 5 has been reset in the frame 1; The controller instructs the clamping electric cylinder 41 to extend, and the main linkage plate 42 swings and loosens along the driving gear 43. The first clamping jaw 33 equipped with the clamping boss 35 swings in the loosening direction driven by the main linkage plate 42. At the same time, the driving gear 43 drives the first transition gear 44, the second transition gear 45 and the driven gear 46 to rotate, so that the driven gear 46 drives the driven link plate 47 to swing, and the driven link plate 47 drives the second clamping jaw 34 to swing in the loosening direction. At the same time, when the first clamping jaw 33 swings, the induction block 39 rotates accordingly. When the induction block 39 detects a signal by the clamping position detection switch 38a, it is considered that the first clamping jaw 33 and the second clamping jaw 34 have been loosened in place. At this time, the clamping boss 35 is completely disengaged from the clamping groove 51 on the material box 5, and the flip assembly 3 is in a loosened state. Then the control system instructs the conveyor to reverse, and the empty material box 5 is returned along the conveyor belt and transferred to the empty box conveyor line. The conveyor waits for the next full material box, and this cycle is repeated to realize the dumping of bulk materials.

[0024] For example 3, please refer to Figure 1-11 , the two limit rods 36 are also equipped with an adsorption assembly 6, the adsorption assembly 6 includes a suction machine 61, the facing surfaces of the two suction machines 61 are provided with a plurality of air inlets 62, the facing surfaces of the two suction machines 61 are slidably connected with a collection box 63, a connecting pipe 64 is also provided between the two suction machines 61, and the two ends of the connecting pipe 64 are respectively connected to the two suction machines 61, a discharge pipe 65 is also installed on one of the suction machines 61, and a synchronous gear 48 is also rotatably connected to the flip shaft 31, The synchronous gear 48 is arranged below the second transition gear 45, and the synchronous gear 48 meshes with the second transition gear 45. A synchronous rack 49 is arranged below the synchronous gear 48, and the synchronous rack 49 meshes with the synchronous gear 48. The synchronous rack 49 is slidably connected to the flip shaft 31, and a touch rod is also arranged at one end of the synchronous rack 49. A control switch for controlling the start of the adsorption component 6 is arranged on the flip shaft 31, and the control switch is arranged on a side of the flip shaft 31 close to the touch rod; When the clamping electric cylinder 41 starts to drive the clamping assembly to fix the material box 5, the second transition gear 45 simultaneously drives the synchronous gear 48 to rotate, so that the synchronous gear 48 drives the synchronous rack 49 to move. When the synchronous rack 49 moves, the touch rod at the end of the synchronous rack 49 gradually contacts the control switch. When the synchronous rack 49 is completely in contact with the control switch, the control switch controls the suction machine 61 to start and close the connecting pipe 64 and the discharge pipe 65. When the flip shaft 31 drives the material box 5 to dump the material, the dust generated during the dumping is adsorbed by the suction machine 61, and the adsorbed dust is concentrated in the collection box 63, which is convenient for unified cleaning. Meanwhile, when the dumped material is powder, the connecting pipe 64 and the discharge pipe 65 are opened and the collecting box 63 is closed. When the flip shaft 31 flips, the suction machine 61 absorbs the material scattered during the dumping. The powder absorbed by one suction machine 61 is transported to the other suction machine 61 through the connecting pipe 64 and discharged through the discharge pipe 65, thereby reducing the waste of powder. When the flip shaft 31 is reversed and reset, the second transition gear 45 simultaneously drives the synchronous gear 48 to reverse and reset the synchronous rack 49. After the synchronous rack 49 is reset, the touch rod is no longer in contact with the control switch, and the suction machine 61 is turned off.

[0025] The working principle of the present invention is as follows: when in use, the material box 5 filled with materials is transported from the full material conveying line to the material unloading machine via the conveyor, the controller instructs the clamping electric cylinder 41 to contract, and the first clamping jaw 33 and the second clamping jaw 34 equipped with the clamping boss 35 are driven by the main linkage plate 42 and the driven link plate 47 to swing in the tightening direction. When the first clamping jaw 33 swings, the induction block 39 rotates accordingly. When the induction block 39 is detected by the clamping position detection switch 38a, it is considered that the first clamping jaw 33 and the second clamping jaw 34 have been clamped in place, and at this time, the clamping boss 35 is just engaged with the clamping groove 51 of the material box 5; The controller instructs the driving motor 21 to start. Driven by the driving motor 21, the flip assembly 3 rotates in the flipping direction, and the material in the material box 5 falls from the discharge port. When the induction sheet 37 installed on the second transmission sprocket 23 is detected by the flip position detection switch 38b, it is considered that the material box 5 has been flipped in place, and the flip assembly 3 stops rotating. At this time, the material is in a completely dumped state, and all the material is poured into the receiving area; After the dumping action is completed, the controller instructs the drive motor 21 to reverse, and the flip shaft 31 rotates in the opposite direction. When the limit rod 36 contacts the limit switch 13, the drive motor 21 stops rotating. At this time, the empty material box 5 has fallen on the conveyor belt of the conveyor. The photoelectric switch 11 and the matching reflector 12 detect that the material box 5 has entered the dumper. The controller instructs the clamping electric cylinder 41 to extend, and the first clamping jaw 33 and the second clamping jaw 34 are released in place. At this time, the clamping boss 35 is completely disengaged from the clamping groove 51, and the flip assembly 3 is in a released state. Then the controller instructs the conveyor to reverse, and the empty material box 5 is returned along the conveyor belt and transferred to the empty box conveyor line. The conveyor waits for the next full material box, and this cycle is repeated to realize the dumping of bulk materials.
