Description

Technical Field

[0001] The present application relates to the technical field of automatic feeding equipment, and in particular to a material feeding machine capable of realizing sealed feeding of a powder bucket. Background Art

[0002] In a traditional processing production line, the method of lifting a powder bucket to a platform at a certain height and pouring the powder in the bucket into a funnel-type vibrating screen for sieving usually includes the following operating steps: First, the bucket is lifted to the platform height. Usually, a lifting device (such as a lift, a conveyor belt, etc.) is used to lift the bucket or container storing the powder to a height where the operator can easily operate. Then, the operator inverts the bucket or container so that the powder passes through the vibrating screen with a funnel. The function of the vibrating screen is to evenly distribute the powder through vibration and filter out larger or unnecessary particles to ensure product quality and uniformity.

[0003] The above traditional feeding and dosing scheme has the following defects in practical applications:

[0004] The staff needs to manually invert the bucket and pour the powder on the platform, which not only has a high working intensity but also has a certain safety risk of working at heights. At the same time, the above feeding and dosing method is an open feeding method, and the powder is easy to splash out during the feeding process, which is likely to generate dust. After the dust spreads, it not only affects the health of the staff but also requires additional cleaning and treatment measures, increasing the cleaning and environmental protection costs. In addition, during the open feeding process, the powder is in contact with the air, and the material is easily contaminated. Moreover, the above feeding and dosing method is highly dependent on manual labor, resulting in a low overall production efficiency. Therefore, it is necessary to propose a new technical solution to solve the problems existing in the prior art. Summary of the Utility Model

[0030] The present application will be further described in detail below with reference to the drawings and through specific embodiments.

[0031] In the description of this application: Unless otherwise specified, "a plurality of" means two or more. Terms such as "first" and "second" in this application are intended to distinguish the objects being referred to, and do not have special significance in terms of technical connotations (for example, they should not be understood as emphasizing importance or order, etc.). Expressions such as "including", "comprising", and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0032] Terms such as "upper", "lower", "top", "bottom", "middle", etc. cited in this application are usually for the convenience of intuitively understanding with reference to the attached drawings, rather than an absolute limitation of the positional relationship in the actual product. Without departing from the technical concept disclosed in this application, changes in these relative positional relationships should also be regarded as within the scope of the expression of this application.

[0033] To solve the problems existing in the prior art, this application provides a material feeding machine for sealed feeding. Refer to Figure 1 , which mainly includes five functional parts: a lifting part 2, a flipping part 3, a clamping part 4, a control box 5, and a moving part 1. In a specific production application example, the moving part 1 can be retained or discarded according to the usage needs. After discarding the moving part 1, the lifting part 2, the flipping part 3, the clamping part 4, the control box 5, etc. can be installed on the reserved base. When the equipment needs to be moved during actual use, it can be driven by an existing moving device such as a moving trolley. Of course, directly integrating the moving part on the material feeding machine provided in this application can improve the flexibility of the equipment.

[0034] Next, the structural composition and operation process of each functional part of the material feeding machine of this application will be described one by one.

[0035] I. Lifting part

[0036] Refer to Figure 4 , 5 The lifting part 2 in this application mainly includes a trolley guide rail 21, a trolley assembly 28 arranged on the trolley guide rail 21, a plurality of position monitoring sensors, and a sliding drive assembly 22 for driving the trolley assembly 28 to move along the trolley guide rail 21.

[0037] The sliding drive assembly 22 includes a lifting motor 23, a driving sprocket 24 connected to the output shaft of the lifting motor 23, a driven wheel assembly 26 drivingly connected to the driving sprocket 24 through a first transmission chain 25, and a top sprocket assembly 29 drivingly connected to the driven wheel assembly 26 through a second transmission chain 27. It can be seen that in this application, a stable drive system is constituted by the lifting motor 23, transmission sprockets and transmission chains. By controlling the movement of the transmission chain through the lifting motor 23, the trolley assembly 28 can move up and down along the trolley guide rail 21, with smooth and stable operation, avoiding possible friction and jamming phenomena, and ensuring the long-term reliable operation of the equipment.

[0038] The trolley guide rail 21 is vertically arranged, with a track groove vertically opened thereon. The driven wheel assembly 26 is arranged at the bottom of the trolley guide rail 21, the top sprocket assembly 29 is arranged at the top of the trolley guide rail 21, and the second transmission chain 27 is wound around the trolley guide rail 21.

[0039] The trolley assembly 28 includes a sliding connection plate and trolley wheels arranged on one side surface of the sliding connection plate. The trolley wheels are slidably connected to the track groove on the trolley guide rail 21 in a matching manner. The sliding connection plate is fixedly connected to the second transmission chain 27, and an installation position for mounting the fixed frame 31 of the flipping part 3 is formed on the sliding connection plate. In this application, the trolley assembly 28 is adapted to the track groove of the trolley guide rail 21 through the sliding connection plate and the trolley wheels. This design not only ensures the compactness of the structure, but also reduces friction loss, improving the stability and operation efficiency of the trolley assembly 28 on the guide rail.

[0040] In this application, the driven wheel assembly 26 and the top sprocket assembly 29 are vertically corresponding, and the second transmission chain 27 is wound around the driven wheel assembly 26 and the top sprocket assembly 29. When the lifting motor 23 is started forward, the second transmission chain 27 can drive the trolley assembly 28 thereon to move downward along the trolley guide rail 21. When the lifting motor 23 is started in reverse, the second transmission chain 27 can drive the trolley assembly 28 thereon to move upward along the trolley guide rail 21.

[0041] In order to achieve in-place detection, a plurality of position monitoring sensors are arranged on the trolley guide rail 21. In this embodiment, the plurality of position monitoring sensors are sequentially arranged from bottom to top along the length direction of the trolley guide rail 21, and are respectively: a lower photoelectric detection limit sensor 210, a lower photoelectric detection in-place sensor 211, a flipping position photoelectric detection in-place sensor 212, an upper photoelectric detection in-place sensor 213, and an upper photoelectric detection limit sensor 214.

[0042] Specifically, the lower photoelectric detection limit sensor 210 described above is used to detect whether the trolley assembly 28 reaches the bottom limit position of the trolley guide rail 21; the lower photoelectric detection in-place sensor 211 is used to detect whether the trolley assembly 28 reaches the bottom preset position of the trolley guide rail 21; the flip-position photoelectric detection in-place sensor 212 is used to detect whether the trolley assembly 28 reaches the target flip position of the trolley guide rail 21; the upper photoelectric detection in-place sensor 213 is used to detect whether the trolley assembly 28 reaches the top preset position of the trolley guide rail 21; the upper photoelectric detection limit sensor 214 is used to detect whether the trolley assembly 28 reaches the top limit position of the trolley guide rail 21. Each of the above position monitoring sensors is respectively connected to the processor in the control box 5 by signal, and the processor can obtain the signal representing the position of the trolley assembly 28 through the position monitoring sensors.

[0043] The above-mentioned multiple position monitoring sensors are arranged along the length direction of the trolley guide rail 21. They not only perform limit detection at the limit positions of the trolley assembly 28 (the bottom limit position and the top limit position), but also include the monitoring of the preset position and the target flip position. These position monitoring sensors are connected to the processor in the control box 5 by signal, and can timely feedback the position information of the trolley assembly 28, realizing the comprehensive monitoring and safety control of the equipment operation state, accurately detecting the position of the trolley assembly 28. This precise position control can ensure that the equipment stops and positions accurately during operation, improving the overall operation efficiency and safety.

[0044] In this application, a lower mechanical limit 215 is also provided at the bottom of the trolley guide rail 21, and an upper mechanical limit 216 is provided at the top of the trolley guide rail 21. During the ascending and descending process of the trolley assembly 28, the upper mechanical limit 216 and the lower mechanical limit 215 can prevent the trolley assembly 28 from exceeding the design range, thereby avoiding accidents or damage to the equipment.

[0045] II. Flip part

[0046] See Figure 6 , the flip part 3 in this application mainly includes a fixed frame 31 arranged on the trolley assembly 28. A rotating flange 33, a flip initial position monitoring sensor 36 for monitoring the rotation position of the rotating flange 33, and a flip in-place monitoring sensor 34 are arranged on the outer wall of the fixed frame 31. A flip drive assembly 32 for driving the rotation of the rotating flange 33 is installed inside the fixed frame 31.

[0047] Specifically, the rotating flange 33 and the pulley assembly 28 are oppositely arranged on both sides of the fixed frame 31. The initial position monitoring sensor 36 for flipping is arranged above the rotating flange 33, and the in-place monitoring sensor 34 for flipping is arranged below the rotating flange 33. The flipping drive assembly 32 includes a flipping motor installed in the fixed frame 31, and the power output end of the flipping motor is connected to the rotating flange 33. Two rotating limit grooves are formed on the outer wall of the rotating flange 33 facing the fixed frame 31. The two rotating limit grooves are centrosymmetric about the central position of the rotating flange 33. Two overload mechanical limits 37 are arranged on the fixed frame 31, and one overload mechanical limit 37 corresponds to one rotating limit groove.

[0048] When the flipping motor drives the rotating flange 33 to rotate forward, the rotating flange 33 rotates forward by 180 degrees and is detected by the in-place monitoring sensor 34 for flipping, and then the flipping motor stops. When the rotating flange 33 is driven by the flipping motor to rotate back, the rotating flange 33 rotates backward by 180 degrees and is detected by the initial position monitoring sensor 36 for flipping, and then the flipping motor stops. During the rotation process, if the photoelectric fails, the overload detector 35 functions to stop the flipping motor. The reserved rotating limit grooves corresponding to the rotating process on the rotating flange 33 correspond to the overload mechanical limits 37 on the fixed frame 31. When the detection fails, both ends of the rotating limit groove will contact the overload mechanical limit 37, forcing the rotating flange 33 to stop rotating, thereby protecting the safety of the equipment and operators.

[0049] The initial position monitoring sensor 36 for flipping and the in-place monitoring sensor 34 for flipping used in this application can accurately detect the rotation state of the rotating flange 33. Through these sensors, it can be ensured that the rotating flange 33 stops when rotating to a specified angle (such as 180 degrees), thereby achieving an accurate rotation action. This can not only ensure the safety and stability of the operation, but also provide real-time feedback on the operating state, facilitating fault diagnosis and maintenance. Moreover, this application adopts a flipping motor to be responsible for driving the rotation of the rotating flange 33. This design ensures the stability and reliability of the rotation action, and ensures the accuracy and consistency of each flipping action.

[0050] III. Clamping Part

[0051] See Figure 3, the clamping part 4 in this application mainly includes a rotating frame 41 installed on the rotating flange 33 and a clamping assembly installed on the rotating frame 41. The clamping assembly includes two relatively arranged clamping arms 42, a clamping driving cylinder 43 used to drive the two clamping arms 42 to approach or move away from each other to clamp and release the drum 46, and a photoelectric detection sensor 44 used to monitor whether the two clamping arms 42 are in the initial open state. A drum cover assembly 47 is also arranged on the rotating frame 41. The drum cover assembly 47 includes a funnel-shaped drum cover arranged above the two clamping arms 42 and adapted to cover the drum 46, and a discharging valve group arranged at the top of the funnel-shaped drum cover.

[0052] The structural design of the funnel-shaped drum cover in this application can facilitate the discharging after the drum 46 is overturned. And the top of the funnel-shaped drum cover is connected to the feeding pipeline of the vibrating screen through the discharging valve group, which is convenient to operate and has reliable connection. In this application, the photoelectric detection sensor 44 ensures that the clamping arms 42 are in the correct initial open state, avoiding misoperation or safety risks during the operation.

[0053] A clamping frame is arranged on the rotating frame 41 in this application. The clamping frame and the rotating flange 33 are arranged on both sides of the rotating frame 41 relatively. The clamping driving cylinder 43, the two clamping arms 42 and the photoelectric detection sensor 44 are all arranged on the clamping frame. The two clamping arms 42 are arranged relatively in the horizontal direction, and the two clamping arms 42 jointly enclose a clamping space adapted to clamp the drum 46. The clamping arm 42 includes a first straight rod section connected to the rotating frame 41 and a second straight rod section connected to the first straight rod section and forming an angle. The second straight rod section inclines towards the clamping space. Arc-shaped retaining rings 45 are respectively arranged on the inner sides of the first straight rod section and the second straight rod section. The arc-shaped retaining rings 45 are used to fit and adhere to the outer wall of the drum 46.

[0054] The clamping arm 42 in this application is composed of a first straight rod section and a second straight rod section, and the arc-shaped retaining rings 45 are arranged on the inner side, which can be well adapted to the outer wall of the drum 46, ensuring stable and reliable clamping effect. In this application, the clamping arms 42 are driven by the clamping driving cylinder 43, and the magnetic switch 410 is used to detect whether the drum 46 is clamped, ensuring the accuracy and safety of the clamping action. In this application, through the arrangement of the rotating frame 41 and the clamping frame, the effective fixation and integration of key components such as the clamping driving cylinder 43, the clamping arms 42 and the sensor are realized, improving the stability and durability of the overall structure.

[0055] A magnetic switch 410 is also provided on the clamping frame, and the magnetic switch 410 is used to detect whether the barrel 46 is clamped by the two clamping arms 42; a fixing rod is respectively provided above the two clamping arms 42, one end of the fixing rod is connected to the rotating frame 41, and the other end is tightly connected to the outer wall of the funnel-shaped barrel cover, and the top of the funnel-shaped barrel cover extends in the direction away from the clamping space; the unloading valve group includes a manual butterfly valve 48 and a rotary valve 49 arranged on the top of the funnel-shaped barrel cover.

[0056] When the material barrel 46 is placed in the positioning area of the material barrel 46, the flip part 3 and the clamping part 4 fall with the pulley assembly 28, and the barrel cover assembly 47 docks with the material barrel 46. After the docking is completed, the clamping drive cylinder 43 is started, driving the two clamping arms 42 to make the four arc clamps 45 closely contact with the outer wall of the material barrel 46 to play a clamping role; the function of the magnetic switch 410 is to detect whether the material barrel 46 is clamped; the function of the photoelectric detection sensor 44 is to determine whether the two clamping arms are open; the manual butterfly valve 48 is opened when the material barrel 46 is docked with the vibrating screen feeding pipeline for unloading. The manual butterfly valve 48 mainly plays the role of conducting unloading. It can also be replaced by conventional valves such as ball valves and stop valves. The rotary valve 49 mainly plays the role of uniform material discharge and smooth discharge.

[0057] 4. Control box

[0058] The control box 5 is provided with a processor connected to the signals of the above-mentioned position monitoring sensor, the initial position monitoring sensor 36 of the flipping, the in-position monitoring sensor 34 of the flipping, and the photoelectric detection sensor 44. The processor receives and processes the signals from each sensor, and judges whether the clamping arm is in the correct position, whether the barrel is clamped, whether the flipping device has completed the flipping, etc. according to the received signal state, so as to control the actions of each actuator connected to its signal. For example, after the processor receives the signal from the flipping photoelectric detection in-position sensor 212, it sends control signals to the lifting motor 23 and the flipping motor respectively to realize the corresponding action control.

[0059] 5. Mobile Department

[0060] See also Figure 1 , 2 The mobile part 1 in the present application includes a first frame for installing a pulley guide rail 21 and a second frame for installing a control box 5. The first frame and the second frame are connected. Two directional wheels 12 are arranged at one end of the first frame away from the second frame, and two universal wheels 11 are arranged at one end of the second frame away from the first frame. The first frame can be a whole flat plate or two parallel cross bars, as long as it can play a supporting and installing role. The second frame can be a whole flat plate or a frame structure, as long as it can achieve the supporting and installing role. The mobile part 1 can achieve arbitrary steering through the universal wheels 11 at the bottom and achieve direction guidance through the directional wheels 12.

[0061] In a specific application example, the working process of feeding materials by the material feeding machine for sealed feeding provided by the present application is as follows:

[0062] An optoelectronic sensor can be set in the bucket positioning area, and the optoelectronic sensor can be set on the moving part or at a lower position of the flipping part. When the powder bucket 46 is moved to the bucket positioning area by the moving trolley, the device is started. The positioning optoelectronic sensor returns a signal, and the lifting motor 23 is started to rotate forward. The pulley block assembly 28 drives the flipping part 3 and the clamping part 4 to move downward along the pulley guide rail 21. In the present application, a positioning optoelectronic sensor is provided on the bucket cover assembly. When the positioning optoelectronic sensor detects the bucket 46, the bucket cover assembly 47 of the clamping part 4 correspondingly covers the bucket 46. The lifting motor 23 is shut down, and the connecting quick clamp is manually installed to tightly connect the bucket cover assembly 47 and the bucket 46. After the quick clamp installation is completed, the device is started again. The clamping drive cylinder 43 drives the two clamping arms 42 to approach each other, so that the four arc hoops 45 are in close contact with the outer wall of the bucket 46. After the magnetic switch 410 on the clamping drive cylinder 43 detects a signal, it indicates that the bucket 46 has been clamped. The lifting motor 23 starts in the reverse direction. The pulley block assembly 28 drives the flipping part 3 and the clamping part 4 that holds the bucket 46 to move upward. After rising to a certain height and reaching the target flipping position, it is detected by the flipping position optoelectronic detection in-place sensor 212. The lifting motor 23 stops moving, and the flipping motor is started. The bucket 46 starts to rotate forward 180° driven by the rotating flange 33. When the flipping-in-place monitoring sensor 34 detects a signal, the flipping motor stops moving. The lifting motor 23 is started again, and the bucket 46 continues to rise. After the upper optoelectronic detection in-place sensor 213 detects a signal, the lifting motor 23 stops moving. At this time, the bucket 46 has reached the end position, and the device stops. Then, the operator manually docks the discharge valve group with the feed pipeline of the vibrating screen, opens the manual butterfly valve 48, and starts the rotary valve 49 to feed materials evenly. After the feeding is completed, the rotary valve 49 and the manual butterfly valve 48 are closed. The operator manually separates the discharge valve group from the feed pipeline of the vibrating screen, starts the device again, the lifting motor 23 is started to drive the bucket 46 to descend. After descending to the target flipping position, the flipping position optoelectronic detection in-place sensor 212 detects a signal, the lifting motor 23 stops moving, the flipping motor is started, the bucket 46 rotates 180° driven by the rotating flange 33. When the flipping initial position monitoring sensor 36 detects a signal, the flipping motor stops moving. The lifting motor 23 is started again, and the bucket 46 continues to descend. After the lower optoelectronic detection in-place sensor 211 detects a signal, the lifting motor 23 stops moving. The operator removes the connecting quick clamp used to connect the bucket 46 and the bucket cover assembly 47, and then starts the drive motor to make the pulley block assembly 28 drive the flipping part 3 and the clamping part 4 to rise. The bucket cover assembly 47 is separated from the empty bucket 46, and the empty bucket 46 is removed.

[0063] In summary, the present application provides a material feeding machine for sealed feeding. The powder material barrel is automatically clamped by the clamping part, and the barrel is sealed by the barrel cover assembly. The clamped barrel is lifted to the target height by the lifting part, and then the barrel is flipped by the flipping part so that the barrel cover assembly faces downward. The operator can dock the discharge valve group on the barrel cover assembly with the feeding pipeline of the vibrating screen, and then open the discharge valve group to achieve sealed feeding. During the feeding process, no material dust escapes and there is no material pollution, eliminating the health impact of dust on the operator. After the feeding is completed, the operator separates the discharge valve group from the feeding pipeline of the vibrating screen. Then, the material feeding machine provided by the present application lowers the inverted empty barrel through the lifting part, flips it back to the normal position, and continues to lower it in place. Then, the operator removes the quick clamp connecting the barrel cover assembly and the barrel, separating the barrel cover assembly from the barrel and removing the empty barrel. Therefore, the material feeding machine provided by the present application realizes functions such as automatic lifting, lowering, clamping, and flipping of the barrel through the cooperation of multiple functional components, improving the automation degree of feeding, reducing the manual participation and working intensity, reducing the labor cost, and improving the working efficiency.
