Description

Technical Field

[0001] This utility model relates to the field of automatic drum unloading machine technology, and in particular to a clamping, flipping, vibrating unloading mechanism for a fully automatic drum unloading machine. Background Technology

[0002] Before the advent of automatic drum unloading machines, the industrial sector generally relied on manual methods for drum unloading. This method had several technical shortcomings: First, it was labor-intensive, requiring operators to manually handle drums weighing 20 to 50 kilograms, which limited daily production capacity to less than 200 drums. Second, pollution control was weak; the dust concentration generated during manual operation reached as high as 15 mg / m³ (three times the national standard), and the water consumption for washing waste drums reached 30 liters per drum, which clearly did not meet the requirements of green production. Utility Model Content

[0003] The purpose of this invention is to provide a clamping, flipping, vibrating unloading mechanism for a bucket unloading machine that can achieve efficient automatic separation of materials from the bucket.

[0004] To achieve the above objectives, this utility model proposes a clamping, flipping, vibrating, and unloading mechanism for a fully automatic drum unloading machine, comprising: a flipping bracket, a gripping assembly, a gripping cylinder component, a vibration assembly, an active rotating drum component, and a rotating drum motor assembly; The gripping assembly and the vibration assembly are mounted on the tilting bracket; One end of the gripper cylinder component is connected to the flipping bracket, and the other end of the cylinder extension is connected to the gripper assembly; when the cylinder extends, it drives the gripper to move inward, thereby clamping the material bucket. The rotary drum motor assembly is connected to the active rotary drum component via a synchronous belt drive; The flipping bracket is fixedly connected to the flipping shaft driven by the servo motor, so that the servo motor can drive the flipping bracket and its components to flip. The gripping component, the vibration component, and the active rotating drum component work together to separate and release the material in the hopper.

[0005] Furthermore, the gripping assembly forms an adaptive clamping structure through the gripper cylinder component. The gripping assembly includes a pair of opposing grippers, a gripper rotation shaft, and a gripper fixing seat. The gripper fixing seat is fixed to the flipping bracket, the gripper rotation shaft is rotatably mounted on the gripper fixing seat, and the grippers are fixed to the gripper rotation shaft. The inner sidewall of the gripper is an arc-shaped surface, and its inner arc radius is adapted to a material bucket with a diameter of 200-600mm.

[0006] Furthermore, a front gripper roller is also mounted on the inner side of the end of the gripper via a gripper shaft.

[0007] Furthermore, the vibration assembly includes a vibration mounting base, a vibration mounting plate, a vibration motor, and a spring; The vibration fixing seat is fixed on the flip bracket and connected to the vibration mounting plate by a spring; The vibration motor is fixedly mounted on the vibration mounting plate; a driven rotating drum component is also mounted on the vibration mounting plate.

[0008] By incorporating a vibration component, the adhesion between the material and the barrel wall is effectively disrupted.

[0009] Furthermore, the active rotating drum component includes a rotating roller, a rotating support shaft, a drum bearing seat, and a driven synchronous pulley for transmission connection with the rotating drum motor assembly: the driven synchronous pulley is mounted on the rotating support shaft and is used to receive power from the rotating drum motor assembly, thereby driving the rotating support shaft to rotate; the rotating roller is fixedly mounted on the rotating support shaft and is used to directly contact the outer wall of the drum, and under the drive of the rotating support shaft, it drives the drum to rotate by friction.

[0010] Furthermore, it also includes a proximity switch for detecting the flipping angle and a bottom support plate for supporting the material bucket, wherein the proximity switch is disposed on the flipping bracket and the bottom support plate is disposed at the bottom of the flipping bracket.

[0011] Furthermore, the clamping force of the gripper is provided by the pneumatic system of the gripper cylinder component. The air pressure adjustment range of the pneumatic system is 0.4-0.8MPa. By setting the gripper with adjustable air pressure, adaptive clamping of material barrels of different specifications is achieved.

[0012] Furthermore, the servo motor driving the tilting axis is equipped with a reducer with a reduction ratio of 1:90.

[0013] Furthermore, the flip angle is 0-180°.

[0014] Compared with the prior art, the advantages of this utility model are: This novel mechanism, with its adaptive clamping structure, can firmly grasp material buckets of different sizes, ensuring safe and reliable operation. During the flipping process, the combination of high-frequency vibration and the active rotational pressure of the rollers effectively breaks down the adhesion between the material and the bucket wall, allowing viscous or lumpy materials to completely detach, significantly improving the thoroughness of bucket removal and production efficiency. Simultaneously, the fully enclosed mechanized operation greatly reduces dust escape and noise pollution, improving the working environment. The device has a reasonable structure and coordinated movements. Through highly automated mechanical integration and collaborative operation, it cleverly integrates clamping, flipping, vibration, and rotary extrusion functions into one unit, changing the traditional manual bucket removal operation mode and achieving a highly efficient, thorough, and clean bucket removal process. While ensuring high production capacity, it also possesses excellent environmental characteristics and adaptability. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be further described below.

[0018] This embodiment proposes a clamping, flipping, and vibrating descrambling mechanism for a fully automatic drum descrambling machine, such as... Figure 1-7 As shown, the mechanism includes a tilting shaft 9, a tilting bracket 1, a gripping cylinder component 2, a gripping assembly 3, a vibration assembly 4, an active rotating drum component 5, and a rotating drum motor assembly 6. Two identical tilting shafts 9 are bolted to the left and right sides of the tilting bracket 1 in an axisymmetric manner via tilting flanges 7. The tilting shafts 9 at the left and right ends of the tilting bracket 1 are respectively mounted in the corresponding tilting support seats 13 via rolling bearings to form a rotating pair: that is, the tilting shafts 9 can rotate freely, while the tilting support seats 13 are stably fixed to the frame via the tilting drum mounting seat 12, providing stable support for the entire tilting mechanism.

[0019] The gripping assembly 3 is rotatably mounted on the tilting bracket 1, forming an adaptive clamping structure through the gripping cylinder component 2. The active rotating drum component 5 and the vibration component 4 are mounted side by side on the tilting bracket 1; the active rotating drum component 5 is connected to the rotating drum motor component 6 via a synchronous belt.

[0020] The flipping shaft 9 on the right side of the flipping bracket 1 is rigidly connected to the flipping drive shaft 8 on the same axis. Figure 5 As shown, the end of the flip drive shaft 8 is coaxially connected to the output end of the flip servo motor 14 via a coupling, so that the servo motor 14 drives the flip bracket 1 and its components to flip via the flip drive shaft 8, with a flip angle of 0-180°. In this embodiment, the servo motor 14 is also equipped with a reducer with a reduction ratio of 1:90.

[0021] In this embodiment, as Figure 7 As shown, the gripper assembly 3 includes a pair of opposing grippers, a gripper rotation shaft 3-5, and a gripper fixing seat 3-6. Each gripper consists of two parallel arc-shaped rods (grip rods) 3-1 sleeved on the gripper rotation shaft 3-5. The inner wall of each rod is arc-shaped, and the inner radius has an adaptive adjustment function, suitable for material barrels with a diameter of 300-600mm. A front gripper roller 3-2 is mounted on the inner side of the ends of the two parallel arc-shaped rods 3-1 via the gripper shaft 3-3. The gripper fixing seat 3-6 is fixed to the tilting bracket 1, and a gripper bearing (model OFG31-d15-L20) 3-4 is embedded inside. The gripper rotation shaft 3-5 is mounted via the gripper bearing 3-4, allowing the gripper rotation shaft 3-5 to be rotatably fixed to the gripper fixing seat 3-6. A gripper thrust shaft 3-7 is also provided between the parallel arc-shaped rods of the grippers 3-1, such as... Figure 7 As shown, the gripping thrust shaft 3-7 is fixed to the arc-shaped rods at both ends by screws, which strengthens the gripper structure. Additionally, a gripping cylinder component 2 is installed between the gripping assembly 3 and the tilting bracket, such as... Figure 1 and Figure 2As shown, one end of the gripping cylinder component 2 is connected to the tilting bracket 1, and the other end is the cylinder extension end, which is connected to the gripper thrust shaft 3-7 between the parallel arc-shaped rods of the gripper. When the two gripping cylinder components 2 mounted on the gripper extend, they drive the two opposing grippers to move inward, thereby clamping the material bucket. The clamping force of the gripper is provided by the pneumatic system of the gripping cylinder component 2, and the air pressure adjustment range of the pneumatic system is 0.4-0.8MPa.

[0022] In this embodiment, as Figure 6 As shown, the vibration assembly 4 includes a vibration mounting base 4-4, a vibration mounting plate 4-1, a 220V 30W vibration motor 4-2, and a spring 4-3. The vibration mounting base 4-4 is fixed to the tilting bracket 1 and connected to the vibration mounting plate 4-1 via the stainless steel spring 4-3. The vibration motor 4-2 is fixedly mounted on the vibration mounting plate 4-1. A driven drum component 4-5 is rotatably mounted on the back of the vibration mounting plate 4-1 via a bearing seat. When the vibration motor 4-2 starts, the vibration it generates is transmitted through the spring 4-3, thereby driving the driven drum component 4-5 to vibrate.

[0023] In this embodiment, as Figure 4 The active rotating drum component 5 includes a rotating drum 5-1, a rotating support shaft, rotating drum bearing seats 5-2, and a driven synchronous pulley 5-3. The rotating drum 5-1 is keyed and fixed to the middle of the rotating support shaft, allowing it to directly contact the outer wall of the drum and rotate using friction. The driven synchronous pulley 5-3 is keyed and installed at one end of the rotating support shaft to receive power from the rotating drum motor assembly 6. Rotating drum bearings are press-fitted to both ends of the rotating shaft, positioning them on either side of the rotating drum 5-1. The left and right shaft ends, each containing a rotating drum bearing, are placed into the cavities of the two rotating drum bearing seats 5-2, and the bearing seat covers are tightened with bolts to ensure the rotating support shaft is supported by the bearings and can rotate freely. The rotating drum bearing seats 5-2 are then bolted to the tilting bracket 1, allowing the active rotating drum component 5 to be mounted on the tilting bracket 1 via the rotating drum bearing seats 5-2.

[0024] In this embodiment, as Figure 3 As shown, the rotary drum motor assembly 6 is located on the back of the tilting bracket 1 and is connected to the active rotary drum component 5 via a synchronous belt drive.

[0025] The rotary drum motor assembly 6 includes a rotary drum motor, a rotary drum base (made of welded steel plate or cast aluminum), and a drive synchronous pulley. The rotary drum motor is fixed to the rotary drum base, which is bolted to the tilting bracket 1. The drive synchronous pulley is connected to the output shaft of the rotary drum motor and is connected to the driven synchronous pulley 5-3 via a synchronous belt. The output shaft of the rotary drum motor assembly 6 drives the drive synchronous pulley to rotate. The drive synchronous pulley transmits the rotational motion to the driven synchronous pulley 5-3 of the drive rotating component 5 via the synchronous belt. The driven synchronous pulley 5-3 drives the rotating support shaft to rotate, thereby rotating the rotating drum 5-1, applying pressure to the drum, and adjusting the posture of the drum during rotation.

[0026] In this embodiment, the output shaft of the rotary drum motor assembly 6 drives the rotating drum of the active rotary drum component 5 to rotate via a synchronous belt (not labeled in the figure). The active rotary drum component 5 and the driven rotary drum component 4-5 on the vibration assembly 4 work together to clamp and drive the drum to rotate, while applying extrusion force to the drum body and adjusting the posture of the drum during rotation to assist in the material falling off.

[0027] In this embodiment, a proximity switch and a base plate 11 are also installed on the tilting bracket 1. The proximity switch is used to detect the tilting angle; the base plate 11 is located at the bottom of the tilting bracket 1 and is used to support the material bucket. When the gripping assembly 3 successfully grips the material bucket through the gripping cylinder component 2, the tilting servo motor 14 will drive the tilting shaft 9 and adjust the tilting angle through the proximity switch on the tilting bracket 1 to adapt to material buckets of different heights, thereby realizing the tilting movement of the entire tilting bracket 1.

[0028] In this embodiment, as Figure 8 As shown, the back of the flipping bracket 1 is also provided with a rear cover 10, the internal cavity of which covers the rotating drum motor assembly 6 and the driven rotating drum component 4-5 of the vibration assembly 4 on the back of the flipping bracket, forming a protective shell to prevent injury to people during motor operation.

[0029] In this embodiment, the tipping bucket mounting base 12 is the mounting base of the tipping mechanism. It is fixedly installed on the main frame of the fully automatic bucket unloading machine by bolts, located at the connection between the tipping shaft 9 and the tipping drive shaft 8. The tipping bucket mounting base 12 is a rigid welded part, and its main functions are: 1) Transmitting torque and motion: As a key link in the power transmission path, the mounting base 12 efficiently and reliably transmits the rotational torque generated by the servo motor to the tipping bucket through the tipping drive shaft 8 and the tipping shaft 9, thereby driving the tipping bucket to complete a precise tipping action; 2) Ensuring structural stability and alignment: Since its installation position is precisely limited between the rolling bearing and the servo motor, it can effectively ensure the structural stability during the tipping process; 3) The rolling bearing on the inner side of the tipping bucket mounting base 12 provides stable radial support for the tipping shaft, ensuring that the shaft (and the mounting base and tipping bucket installed on it) can rotate smoothly and reduce vibration and jumping.

[0030] The barrel-tilting mechanism for an automatic barrel unloading machine proposed in this embodiment is a key module for achieving efficient barrel lid separation. This clamping, tilting, and vibrating unloading mechanism is equipped with dual-station arc-shaped grippers (made of 304 stainless steel). The inner radius of the grippers is adapted to the barrel diameter (200-600mm), and the clamping force is adjusted via air pressure (0.4-0.8MPa). In the tilting mechanism, a 1.5kW servo motor 14 with a reducer (reduction ratio 1:90) drives the tilting shaft 8. The tilting angle is adjustable from 0-180°, and the angular acceleration reaches 15rad / s², ensuring rapid tilting to the unloading station after the barrel lid is separated.

[0031] The operation process of this utility model is as follows: 1. Feeding and clamping positioning: The material bucket is conveyed to the initial position of the clamping, flipping, and vibrating unloading mechanism, with the bottom of the bucket supported by the base plate 11. Subsequently, the gripping cylinder component 2 actuates, driving the gripping assembly 3 (a pair of arc-shaped grippers) to close, firmly gripping the material bucket from both sides. The rollers 3-2 on the inner side of the grippers are designed to ensure uniform clamping force and can adapt to material buckets of different diameters, preventing slippage or damage to the bucket body.

[0032] Flipping and preparing for unloading: After the gripping action is completed, the control system issues a command. The tilting servo motor 14 starts, driving the tilting drive shaft 8 and tilting shaft 9 to rotate via a high-reduction gearbox. This causes the entire tilting bracket 1 and all its components (including the gripped bucket) to tilt together, typically rotating 180 degrees so that the bucket opening faces downwards. During this process, proximity switches are used to precisely control the final tilting angle to accommodate different unloading height requirements.

[0033] 3. Collaborative Dematerialization Core Stage (Vibration + Rotary Extrusion): Once the material hopper is in position, the core stage of material removal begins immediately. The two functions in this stage operate simultaneously or alternately to achieve optimal results: Vibration Desorption: The vibration mechanism 4, mounted on the tilting bracket 1, begins operation. The vibration motor 4-2 generates high-frequency vibration, which is transmitted to the driven rotating drum component 4-5 via the stainless steel spring 4-3, causing the material drum in contact with the driven rotating drum to vibrate strongly. This effectively breaks up the adhesive layer between the drum wall and the material, making the material loose.

[0034] Rotary stripping: Simultaneously, the rotary drum motor assembly 6 drives the active rotary drum component 5 to rotate via a synchronous belt. The active rotary drum (rotating roller 5-1) contacts the outer wall of the material drum, and through friction, it drives the material drum to rotate slowly within the grippers. This process applies a downward rolling pressure and shearing force to the drum body, further aiding in material detachment; it also ensures that the entire surface of the material drum is processed evenly, eliminating dead zones in the detachment process.

[0035] 4. Unloading and resetting: Under the combined action of vibration and rotational compression, the material is completely detached from the inverted bucket and falls into the collection device or conveyor belt below. After unloading is complete, the vibration and rotation stop. Servo motor 14 reverses and drives the tilting bracket to smoothly rotate the empty bucket 180 degrees, returning it to its initial position with the bucket opening facing upwards. The gripping assembly 3 releases, the empty bucket is removed, and the entire mechanism is ready for the next work cycle.

[0036] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
