[0040] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0041] According to some embodiments of this utility model, refer to Figures 1 to 6The rapid feeding device for ton-bag powder includes a frame 100, a loading plate 200, and an arch-breaking component 300. The frame 100 is equipped with a feeding pipe 120, the axis of which is vertical. The loading plate 200 is located above the frame 100 and is used to support the packaging bag 110. The loading plate 200 has a feeding port 201 in the middle, which is connected to the upper end of the feeding pipe 120. The arch-breaking assembly 300 includes a lever 310, a fulcrum 320, and a loosening device 340. The fulcrum 320 is installed on the wall of the feed pipe 120. The lever 310 is rotatably connected to the fulcrum 320. The loosening device 340 is located inside the feed pipe 120 and is slidably connected to the feed pipe 120 in the vertical direction. One end of the lever 310 is located inside the feed pipe 120 and hinged to the loosening device 340, while the other end of the lever 310 is located outside the feed pipe 120. The end of the lever 310 outside the feed pipe 120 swings around the fulcrum 320 in the vertical direction, which can drive the other end of the lever 310 inside the feed pipe 120 to swing in the vertical direction, thereby driving the loosening device 340 to move in the vertical direction. The fulcrum 320 forms a stable rotational fulcrum with the lever 310 via a pin. When the operator presses the end of the lever 310 located outside the feed tube 120, the torque borne by the fulcrum 320 is distributed to the tube wall of the feed tube 120 through the reinforcing ribs, avoiding local deformation. The up-and-down movement trajectory of the unloader 340 is restricted by the groove inside the feed tube 120, ensuring accurate movement direction and preventing deviation and jamming.

[0042] Understandably, when material needs to be discharged, the packaging bag 110 is placed on the carrier plate 200, with the bag opening facing downwards. The material inside the packaging bag 110 enters the discharge pipe 120 through the discharge port 201, and is then conveyed to the designated location via the discharge pipe 120. During this process, refer to... Figure 3 When one end of lever 310 connected to the feed releaser 340 is pressed down, the feed releaser 340 is at its lowest position, while the other end of lever 310 outside the feed pipe 120 is raised. After the feed inlet 201 is blocked, refer to... Figure 2 and Figure 3 Pressing down on one end of the lever 310 located outside the feed pipe 120 causes one end of the lever 310 connected to the loosener 340 to tilt upwards, thereby causing the loosener 340 to slide upwards. The loosener 340 moves upwards to the feed port 201 and pushes away the material stuck at the feed port 201, thus clearing the feed port 201 and preventing material from getting stuck and unable to feed smoothly. Moreover, the movement of the loosener 340 in the vertical direction can also push away the material blocked in the feed pipe 120, accelerating the material feeding speed.

[0043] This rapid powder unloading device for ton bags has a simple and reliable structure and is easy to operate. It can quickly clear the pipe channel blocked by materials by operating from outside the pipe, avoiding the need to disassemble the pipe and improving work efficiency.

[0044] Furthermore, the fulcrum seat 320 adopts a split design, with the lever 310 held between two symmetrical bearing seats. A pin 160 passes through both bearing seats and the lever 310 simultaneously, thereby achieving a rotatable connection between the fulcrum seat 320 and the lever 310. This design facilitates the installation and maintenance of the lever 310.

[0045] Furthermore, the installation position of the fulcrum 320 can be adjusted according to the diameter of the feed pipe 120. For large-diameter feed pipes 120, the fulcrum 320 is positioned at the reinforcing ribs on the sidewall of the pipe to improve structural stability. It is understood that the reinforcing ribs on the sidewall of the feed pipe 120 enhance local stiffness by increasing material thickness or changing the cross-sectional shape. When the fulcrum 320 is fixed at the reinforcing rib, the torque generated during the operation of the lever 310 is transmitted to the pipe wall of the feed pipe 120 through the fulcrum 320. The reinforcing rib, by increasing the load-bearing area, disperses the concentrated load over a larger area, reducing local stress peaks. This optimizes the load distribution. Positioning the fulcrum 320 at the reinforcing ribs on the sidewall of the feed pipe 120 improves structural stability, allowing the reinforcing ribs to disperse the concentrated load generated during the operation of the lever 310 onto a larger area of ​​the pipe wall by increasing local thickness and stiffness, preventing thin-wall deformation or stress concentration, while simultaneously enhancing vibration and fatigue resistance.

[0046] Furthermore, the inner wall of the feed pipe 120 is provided with a vertically extending groove, and rollers are installed on both sides of the unloader 340. The rollers are connected to the groove, thereby reducing frictional resistance and making it easier for the operator to operate with less effort.

[0047] In another embodiment, the movement trajectory of the loosener 340 is a spiral upward pattern. For example, a protrusion is provided on the outer wall of the loosener 340, and a spiral guide groove is provided on the inner wall of the feed pipe 120. The protrusion on the outer wall of the loosener 340 is inserted into the spiral guide groove. A connecting part is rotatably connected to the lower end of the loosener 340. The connecting part is slidably connected to the feed pipe 120 in the vertical direction. The connecting part is hinged to one end of the lever 310 located in the feed pipe 120. When the connecting part drives the loosener 340 to move vertically, the protrusion is inserted into the spiral guide groove. The protrusion and the spiral guide groove work together to make the loosener 340 rotate simultaneously during the vertical movement. The loosener 340 rotates about its own axis relative to the connecting part, thereby enhancing the arch-breaking effect.

[0048] Furthermore, the surface of the loosener 340 is equipped with an elastic spike-like structure. Upon contact with material blocks, this structure penetrates the material through elastic deformation, further breaking down agglomerates. It can be understood that when the elastic spike-like structure of the loosener 340 contacts a material block, the elastic bending deformation of the spike tips reduces the hard impact resistance, allowing the spikes to embed into the agglomerates. Subsequently, the elastic rebound releases the stored energy to generate high-frequency micro-impacts. That is, the spike tips bend and store energy upon contact with the agglomerates, and after penetrating to a certain depth, they suddenly rebound, releasing energy to form localized shock waves that create micro-cracks within the agglomerates. The alternating action of multiple spikes creates a continuous crushing effect. The combined action of multiple spikes generates shear force and internal stress waves, physically severing particle adhesion and triggering crack propagation, thereby efficiently breaking down agglomerates.

[0049] In one embodiment, when the loosener 340 rises, the spiral guide groove guides the loosener 340 to rotate clockwise, and the elastic barbed structure on the surface of the loosener 340 cuts into the agglomerates in a drilling manner; when the loosener 340 descends, the loosener 340 rotates counterclockwise, and the barbed bodies rebound and generate vibration, thereby accelerating the agglomerate breakage under the dual action of the rotation of the loosener and the rebound vibration of the elastic barbed bodies.

[0050] Furthermore, refer to Figure 7 The arch-breaking component 300 also includes a pin 160, the axis of which is in the front-to-back direction. The pin 160 passes through both the fulcrum seat 320 and the lever 310. The inner wall of the feed pipe 120 is located... Figure 7 On the left side, the outer wall of the feed pipe 120 is located Figure 7 On the right side. The inner wall of the feed pipe 120 is provided with a first conical hole 151, and the outer wall of the feed pipe 120 is provided with a second conical hole 152. The first conical hole 151 and the second conical hole 152 are symmetrically arranged. The diameter of the first conical hole 151 gradually decreases towards the second conical hole 152, and the diameter of the second conical hole 152 gradually decreases towards the first conical hole 151. The lever 310 passes through both the first conical hole 151 and the second conical hole 152. It can be understood that when the lever 310 rotates around the pin 160, it can swing up and down. Preferably, an annular spring part 171 is provided between the first conical hole 151 and the second conical hole 152. The lever 310 passes through the annular spring part 171, and the inner peripheral wall of the annular spring part 171 is in close contact with the outer peripheral wall of the lever 310. The annular spring part 171 plays a sealing role to prevent material from being blown to the outside through the first conical hole 151 and the second conical hole 152. When lever 310 rotates around pin 160, the outer peripheral wall of lever 310 can apply force to the annular spring 171, causing the annular spring 171 to deform, thus preventing lever 310 from colliding and interfering and getting stuck, which would prevent it from rotating.

[0051] Preferred, refer to Figure 7The inner wall of the feed pipe 120 is provided with a baffle curtain 140. The baffle curtain 140 is used to block the port of the first conical hole 151 facing the feed pipe 120, and can prevent the material in the feed pipe 120 from entering the first conical hole 151. The up and down swing of the lever 310 can drive the baffle curtain 140, that is, the baffle curtain 140 will not hinder the swing of the lever 310. The wall of the feed pipe 120 is provided with an air blowing channel 130, and the air outlet of the air blowing channel 130 is connected to the first conical hole 151. The air supply device supplies air to the air blowing channel 130, so that the gas coming out of the air blowing channel 130 can blow the material located in the first conical hole 151 into the feed pipe 120, preventing the accumulation of material in the first conical hole 151 and thus preventing the lever 310 from swinging.

[0052] Furthermore, refer to Figure 6 A vibration motor 210 is installed on the material carrier plate 200. The vibration motor 210 vibrates the material carrier plate 200, thereby vibrating the packaging bag 110. This disperses the material inside the packaging bag 110 and at the discharge port 201, reducing the risk of material clogging the discharge port 201. Furthermore, the vibration motor 210 uses a variable frequency motor in conjunction with an acceleration sensor to achieve intelligent adjustment. When a decrease in material flow rate is detected, the vibration frequency is automatically increased, for example, from 1500 rpm to 2800 rpm. Alternatively, a pneumatic vibrator can be used instead of a motor, generating impact vibration through pulsed airflow, which is suitable for explosion-proof environments.

[0053] Furthermore, refer to Figure 1 and Figure 6 The rapid feeding device for ton-bag powder also includes a shock-absorbing spring 220, which is located between the frame 100 and the material carrier plate 200. The upper end of the shock-absorbing spring 220 is connected to the material carrier plate 200, and the lower end of the shock-absorbing spring 220 is connected to the frame 100. The shock-absorbing spring 220 can reduce the vibration transmitted from the material carrier plate 200 to the frame 100, thus preventing excessive noise caused by vibration of the frame 100.

[0054] Furthermore, refer to Figure 2 and Figure 3 The arch-breaking component 300 also includes a counterweight 330, and the lever 310 is connected to the counterweight 330 at one end located outside the feed pipe 120. The material continuously falling inside the feed pipe 120 applies an equivalent continuous force to the loosener 340, causing the counterweight 330 to be tilted upward.

[0055] It is understandable that the material impacts the loosener 340 during its descent. The continuous impact of the falling material is equivalent to an additional weight applied to the loosener 340. At this time, the sum of the equivalent weights of the loosener 340 and the material is greater than that of the counterweight 330, causing the counterweight 330 to be lifted. Since the difference in gravity between the two is not significant, the operator can press the counterweight 330 down with minimal force, saving time and effort. In one embodiment, when the material blocks the discharge port 201, the loosener 340 loses the equivalent weight of the material. The weight of the counterweight 330 is greater than that of the loosener 340, causing the counterweight 330 to descend and the loosener 340 to be lifted. This causes the loosener 340 to impact the blocked material, dispersing it and allowing the material to continue descending smoothly, thus achieving an automatic dynamic adjustment effect.

[0056] Preferably, the weight of the counterweight 330 is adjustable, and it is equipped with a counterweight compartment and a standard counterweight plate, so that the weight of the counterweight 330 can be changed according to the density of the material.

[0057] Furthermore, refer to Figures 2 to 4 The rapid feeding device for ton-bag powder also includes an air supply device and an air supply switch 410. The air outlet of the air supply device is connected to the inner cavity of the loosener 340 via an air pipe. The outer wall of the loosener 340 is provided with multiple vent holes 341 communicating with the inner cavity of the loosener 340. The air supply switch 410 is electrically connected to the air supply device and is located below the counterweight 330. When the counterweight 330 descends, it presses the air supply switch 410, causing the air supply device to supply air to the loosener 340 through the air pipe. It can be understood that when the counterweight 330 descends and presses the air supply switch 410, the loosener 340 is lifted, thus breaking up the material. At the same time, gas enters the loosener 340 through the lifting pipe and is discharged through the vent holes 341. The gas disperses the material, further scattering it and ensuring that the material falls smoothly.

[0058] Furthermore, refer to Figure 1 and Figure 5The rapid powder feeding device for ton bags also includes multiple first kneading and pushing components 500. These components are mounted on a carrying plate 200 and distributed circumferentially along the carrying plate 200. Each first kneading and pushing component 500 includes a first pushing cylinder 510 and a first pushing plate 520. The first pushing cylinder 510 is mounted on the carrying plate 200, and its drive end is connected to the first pushing plate 520. The first pushing cylinder 510 can drive the first pushing plate 520 closer to or further away from the center of the carrying plate 200. The first pushing plate 520 is arc-shaped, and the first pushing plates 520 of the multiple first kneading and pushing components 500 surround each other to form a bag-laying area 530. The movement of the first pushing cylinder 510 driving the first pushing plate 520 can expand or shrink the bag-laying area 530. Understandably, when the packaging bag 110 is placed on the carrier plate 200, the packaging bag 110 is located in the bag placement area 530. The first pushing cylinder 510 pushes the first pushing plate 520, so that the first pushing plate 520 presses the packaging bag 110. Multiple first pushing plates 520 press the packaging bag 110 in different steps, that is, push the packaging bag 110 back and forth, thereby realizing the kneading and pushing of the packaging bag 110, so that the blocky material inside the packaging bag 110 is pushed apart.

[0059] Preferably, the first push plates 520 of the four first kneading and pushing components 500 are pushed and withdrawn sequentially towards the center of the carrier plate 200 with a 90° phase difference, thereby forming a wave-like kneading effect. The arc-shaped inner surface of the first push plate 520 is in contact with the packaging bag 110, and the side of the first push plate 520 near the center of the carrier plate 200 is provided with an inclined surface, which generates an upward component force on the packaging bag 110 while horizontally squeezing it, causing the material inside the bag to separate into layers.

[0060] Preferably, the first pushing cylinder 510 can be replaced by a servo electric cylinder to achieve precise displacement control. The surface of the first pushing plate 520 is provided with a corrugated silicone layer to ensure the pushing effect while avoiding scratching the packaging bag.

[0061] Furthermore, refer to Figure 1The rapid feeding device for ton-bag powder also includes two second kneading and pushing assemblies 600 symmetrically arranged in the left-right direction. The second kneading and pushing assemblies 600 are mounted on the frame 100 and include a second pushing cylinder 610 and a second pushing plate 620. The second pushing cylinder 610 is mounted on the frame 100 with its drive end facing upwards and connected to the second pushing plate 620. The second pushing cylinder 610 is located below the material carrier plate 200 and can drive the second pushing plate 620 to move upwards towards the center of the material carrier plate 200, or drive the second pushing plate 620 downwards away from the center of the material carrier plate 200. It can be understood that the second pushing plate 620 rises at a 45° angle, with its top end abutting against both sides of the bottom of the packaging bag 110, gathering residual material towards the center while simultaneously supporting the edges of the packaging bag 110 to prevent slippage. The cooperation of the two second kneading and pushing components 600 can push the two sides of the packaging bag 110 on the material carrier plate 200 upward and towards the center, preventing the lower side of the packaging bag 110 from falling onto the material carrier plate 200. In addition, it can push the material on both sides of the bottom of the packaging bag 110 towards the center, ensuring that all the material inside the packaging bag 110 can be removed from the packaging bag 110.

[0062] Furthermore, refer to Figure 2 and Figure 3 The lower end of the feeder 340 is fixedly connected to a connecting arm 350, and the lower end of the connecting arm 350 is hinged to one end of the lever 310 located inside the feed tube 120. The connecting arm 350 is L-shaped, and the rotation of the lever 310 drives the connecting arm 350 to move in the up and down direction. The hinge between the connecting arm 350 and the lever 310 prevents them from jamming together.

[0063] Preferably, the loosener 340 is in the shape of a cylindrical tube and is arranged vertically. The upper end of the loosener 340 can push the material upward. The outer peripheral wall of the loosener 340 is provided with multiple vent holes 341. While the loosener 340 pushes the material upward, gas is blown out from the loosener 340 through the vent holes 341, further dispersing the material and causing it to fall quickly.

[0064] Furthermore, refer to Figure 4The material loosener 340 is tubular and includes a first tube 361 and a second tube 362. The first tube 361 is horizontally positioned to increase the contact area between the first tube 361 and the material in the horizontal direction, thereby facilitating the dispersion of the material. The second tube 362 is inclined. The upper end of the second tube 362 is connected to one end of the first tube 361. Both the first tube 361 and the second tube 362 are provided with multiple vent holes 341. Gas discharged through the vent holes 341 of the first tube 361 can disperse the material, and gas discharged through the vent holes 341 of the second tube 362 can cause the material to fall quickly. During the upward movement of the loosener 340, the horizontally positioned first pipe 361 inserts into the bottom of the material clump with a shoveling action, while the inclined surface of the second pipe 362 pushes the material away in all directions. When the loosener 340 descends, since some material clumps are blocked below part of the loosener 340, the loosener 340 will also push the material clumps downward, thereby accelerating the falling of the material. In addition, the gas ejected from the vent 341 further disperses the remaining clumps.

[0065] Preferred, refer to Figure 3 and Figure 4 The loosener 340 is a tubular structure with its two ends connected, comprising two first tubes 361 and two second tubes 362. The second tubes 362 are located between the two first tubes 361. The upper and lower ends of the second tube 362 on the left are connected to the left ends of the two first tubes 361, respectively, while the upper and lower ends of the second tube 362 on the right are connected to the right ends of the two first tubes 361, respectively. The middle of the second tube 362 is bent towards the other second tube 362, making it Z-shaped. This shape increases the collision area with the material, effectively breaking up any blockages. Simultaneously, gas can be fully dispersed through the vent holes 341 on the loosener 340, thus blowing the material away.
