Description

Technical Field

[0001] The present invention belongs to the technical field of auger feeding devices, and specifically relates to an auger feeding device, a method for adjusting the feed amount using the above-mentioned auger feeding device, a packaging device including the above-mentioned auger conveying mechanism, and a counterweight device of the packaging device including the above-mentioned auger conveying mechanism. Background Art

[0002] As the precision requirements for batching and powder packaging become higher and higher, the mechanical structure and control requirements for the auger feeding unit are also getting higher and higher. Traditionally, a single-axis auger is used with a frequency converter to control the speed of feeding. The traditional single-axis auger uses a frequency converter to control the speed of feeding. A single large auger is used for feeding. Due to the large difference in the characteristics of powder materials, high precision control cannot be achieved. When a single small auger is used for feeding, the production capacity is reduced and the efficiency cannot be improved. The traditional single-axis auger with a frequency converter to control the speed of feeding cannot take into account the dual requirements of production capacity and precision.

[0003] Prior art also discloses a large and small auger feeding mechanism that feeds both the large and small augers simultaneously during fast feed times, while only the small auger feeds during slow feed times to improve feeding accuracy. This structure significantly increases cost, and when handling materials that easily stick to walls, form bridges, or corrode, the small auger often suffers from dry running, rapid wear, and difficulty cleaning, resulting in poor accuracy. Furthermore, the large and small auger feeding mechanism requires dual reduction motor control, resulting in bulky equipment and high manufacturing and maintenance costs. Summary of the Invention

[0004] The purpose of the present invention is to provide an auger feeding mechanism to solve the technical problem that the existing auger feeding mechanism cannot take into account the production capacity, precision and cost.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions, the auger feeding mechanism includes:

[0006] A shell, wherein a feed port and a discharge port are provided on the shell;

[0007] An auger assembly, disposed in the housing, for conveying material from the feed port to the discharge port;

[0008] The throttle is arranged in the shell, and the throttle is a variable diameter structure. The inlet of the throttle is larger than the outlet; the inlet of the throttle is away from the outlet of the auger feeding assembly or is sealed with the outlet of the auger feeding assembly to realize the outlet discharge of the auger conveying assembly or the outlet discharge of the throttle.

[0009] The present invention designs a throttle in the shell, and utilizes the cooperation between the throttle and the outlet of the auger conveying component to realize the switching of the discharge port between two positions, one position is the outlet of the auger conveying component, and the other position is the throttle outlet, which controls both the discharge flow rate and the uniformity of the discharge. The present invention only needs to add a throttle in the shell, and the control is simple to implement, low cost, easy to install and maintain, and takes into account speed and accuracy, as well as cost.

[0010] In order to solve the technical problem of how to move the throttle, the present invention adopts the following technical solution: a throttle driving member is provided on the housing, and the output shaft of the throttle driving member is connected to the throttle.

[0011] The present invention utilizes the throttle driving member installed on the shell to realize the positioning of the throttle and the linear movement of the throttle to realize the switching of the discharge port.

[0012] In order to solve the technical problem that the throttle adopts an integral structure and is inconvenient to install and maintain, the present invention adopts the following technical solution: the throttle is a split structure, including a first throttle and a second throttle connected to each other;

[0013] The throttle driver includes a first throttle driver and a second throttle driver; the output shaft of the first throttle driver is connected to the first throttle via a first connecting member, and the output shaft of the second throttle driver is connected to the second throttle via a second connecting member.

[0014] The present invention designs the throttle to be a symmetrical structure, and a single throttle body corresponds to a driving component, which is convenient for installation and maintenance.

[0015] To further address the technical issue of feed uniformity, the present invention employs the following technical solution: a crushing element is provided at the throttle outlet to crush the material at the throttle outlet. This crushing element at the throttle outlet further crushes the compressed material before it flows into the outlet, further ensuring feed uniformity.

[0016] In order to solve the technical problem of throttle sealing, the present invention adopts the following technical solution: a first seal is set between the first throttle and the second throttle to ensure the sealing after connection; a second seal is set at the inlet of the throttle to ensure the sealing when the throttle is working.

[0017] To address the technical issue of unstable material flow in an auger feed assembly, the present invention employs the following technical solution: the auger assembly includes an auger shaft and blades mounted on the auger shaft, the pitch of the blades gradually increasing from the feed inlet to the discharge outlet of the housing. As the pitch of the blades gradually increases from the feed inlet to the discharge outlet of the housing, material is fed from the rear end and conveyed toward the front end by the rotational extrusion of the smaller-pitch auger blades. As the pitch of the blades increases, the space for material placement is gradually freed up, allowing the material to be conveyed toward the front end at a uniform speed in a relatively loose state, thus facilitating a stable material flow.

[0018] In order to solve the technical problem of the power source of the auger assembly, the present invention adopts the following technical solution: the auger feeding mechanism also includes an auger drive assembly, which is arranged on the shell, and the auger drive assembly is connected to the auger feeding assembly via a first transmission mechanism.

[0019] In order to solve the technical problem of how to implement the first transmission mechanism, the present invention adopts the following technical solution: the first transmission mechanism is a sprocket transmission mechanism, including a first sprocket, a second sprocket, and a first chain. The first sprocket is arranged on the output shaft of the driving assembly, and the second sprocket is arranged at one end of the auger shaft of the auger feeding assembly; the chain is sleeved on the first sprocket and the second sprocket;

[0020] The height between the auger drive assembly and the housing is adjustable, thereby adjusting the center distance between the first sprocket and the second sprocket.

[0021] To address the technical issue of uneven material feed at the housing feed port, the present invention employs the following technical solution: a stirring mechanism is provided at the housing feed port, connected to the auger feed assembly via a second transmission mechanism. The present invention utilizes the stirring mechanism to disperse the material during rotation, dropping it into the rear blades of the auger assembly for transport, ensuring uniform feed.

[0022] In order to solve the technical problem of how to implement the stirring mechanism, the present invention adopts the following technical solution: the stirring mechanism is a horizontal structure, and the stirring structure includes a stirring shell, and a horizontally arranged stirring shaft is rotatably installed on the stirring shell, and a stirring device is provided on the stirring shaft; the second transmission mechanism is a sprocket transmission mechanism, including a third sprocket, a fourth sprocket, and a second chain, the third sprocket is arranged on the stirring shaft of the stirring mechanism, and the fourth sprocket is arranged at the other end of the auger shaft of the auger feeding assembly; the second chain is sleeved on the third sprocket and the fourth sprocket.

[0023] To address the technical issue of the second chain becoming loose after prolonged use, the present invention employs the following technical solution: a tensioning assembly is provided on the housing for tensioning the second chain; the tensioning assembly's position on the housing is adjustable. The tensioning assembly is bolted to the housing's feed end, and a waist-shaped hole is provided at the fixed end of the tensioning assembly to facilitate tensioning the second chain between the third and fourth sprockets.

[0024] In order to solve the technical problem of inconvenient cleaning and maintenance of the feed end of the shell, the present invention adopts the following technical solution: a second inspection door is provided on the shell, and the first inspection door is used to clean and inspect the feed end of the auger feeding mechanism, which is easy to use.

[0025] In order to solve the technical problem of inconvenient cleaning and maintenance of the shell discharge end, the present invention adopts the following technical solution: a first inspection door is provided on the shell, and the first inspection door is used to clean and inspect the discharge end of the auger feeding mechanism and install the throttle, which is easy to use.

[0026] To address the technical issue of inconvenient manual control, the present invention employs the following technical solution: the auger feeding mechanism further includes a control unit, which is connected to the throttle drive and the auger drive assembly. The control unit triggers an electrical signal to signal the throttle drive to be active or inactive, thereby achieving linear motion of the throttle. Simultaneously, the control unit triggers an electrical signal to signal the auger drive assembly to change speed, thereby increasing or decreasing the auger feed speed.

[0027] A second object of the present invention is to provide a method for adjusting the material feed rate, which utilizes any of the above-mentioned auger feeding mechanisms to achieve:

[0028] The throttle drive member drives the throttle away from the outlet of the auger feeding assembly and, at the same time, increases the rotation speed of the auger assembly. The material is quickly spirally conveyed by the auger assembly and then flows directly into the outlet of the housing.

[0029] The throttle drive component drives the throttle to approach and seal the outlet of the auger feeding assembly, and at the same time, reduces the rotation speed of the auger drive assembly, drives the auger assembly to rotate slowly and transport materials, and the material is slowly spirally conveyed into the throttle through the auger assembly, flows out through the throttle outlet, and uses the cross-sectional contraction of the throttle to control the material flow, and then flows into the outlet of the shell.

[0044] During the batching or powder packaging process, a single-axis auger cannot take into account both the production capacity and precision requirements, and large and small double-axis augers cannot handle some special materials that are prone to wall adhesion, bridging, and corrosion. This embodiment provides an auger feeding mechanism.

[0045] like Figure 1 、 2 As shown, the auger feeding mechanism includes an auger feeding mechanism, which includes a housing 400 , an auger assembly 200 , a throttle assembly 300 , and a driving mechanism 100 .

[0046] like Figure 3 As shown, the auger housing assembly 400 includes an auger housing weldment 401, which is used to install and fix all the required parts for feeding and is the carrier of all parts. The housing 400 is provided with a feed port and a discharge port.

[0047] In one embodiment, a first inspection door 405 and a second inspection door 403 are provided on the housing 400. The second inspection door 403 is used for cleaning and inspecting the feed end of the auger feed mechanism, while the first inspection door 405 is used for cleaning and inspecting the discharge end of the auger feed mechanism, as well as for installing a throttle. Specifically, the second inspection door 403 is used for cleaning and inspecting the feed end, and a second inspection door sealing ring 402 is installed in the second inspection door slot plate to ensure a leak-proof seal during normal operation of the equipment. The first inspection door 405 is used for cleaning and inspecting the discharge end, and also facilitates installation of the throttle assembly 300. Similarly, a first inspection door sealing ring 404 is installed in the first inspection door slot plate to ensure a leak-proof seal during normal operation of the equipment.

[0048] The auger assembly 200 is installed in the housing 400 and is used to transport the material from the feed port to the discharge port. Figure 6 As shown, the auger assembly includes an auger shaft and blades disposed on the auger shaft. The auger assembly 200 passes through the auger tube of the housing 400, and the left and right journals are mounted below the housing 400 via seated bearings 106. The seated bearings 106 ensure smooth rotation of the auger assembly 200 without any stagnation.

[0049] In one embodiment, the pitch of the blades gradually increases from the feed inlet to the discharge outlet of the shell. Figure 4As shown, the auger assembly 200 includes an auger shaft 201, blade one 202, blade two 203, blade three 204, blade four 205, blade five 206, blade six 207, blade seven 208, blade eight 209, blade nine 210, blade ten 211, and blade eleven 212. The pitch of the blades decreases from the discharge port to the feed port of the shell. The material is fed from the rear end and is transported to the front end by the rotation and extrusion of the auger blades with a smaller pitch. As the pitch of the blades increases, the space for the material is gradually released, and the material can be transported to the front end at a uniform speed in a relatively loose state, which helps to stabilize the material flow. Figure 1 As shown, the second sprocket 108 and the fourth sprocket 115 are respectively installed at the left and right ends of the auger assembly 200.

[0050] like Figure 5 As shown, the throttle assembly 300 includes a throttle 308 and a throttle driver 301 .

[0051] The throttle 308 is located in the housing 400. The throttle 308 is a variable diameter structure, and the inlet of the throttle 308 is larger than the outlet. Figure 5 As shown, the restrictor 308 is a split structure, which can be a left-right structure or an upper-lower structure. The restrictor 308 includes a first restrictor 3081 and a second restrictor 3082 connected to each other. In one embodiment, a first seal 305 is provided between the first and second restrictors. Specifically, the restrictor 308 is a hollow structure that is split in half. The first seal 305 is installed at the split connection to ensure sealing after the connection. The first and second restrictors are connected together by bolts 303 and nuts 304.

[0052] In one embodiment, a throttle driver 301 is provided on the housing 400, and an output shaft of the throttle driver 301 is connected to the throttle 308. The throttle driver 301 is preferably a cylinder.

[0053] The throttle driver 301 includes a first throttle driver 3011 and a second throttle driver 3012. The output shaft of the first throttle driver 3011 is connected to the first throttle 3081 via a first connecting member. The first connecting member is preferably a cross-shaped mounting bracket with a mounting hole machined thereon. The output shaft of the first throttle driver is fixedly connected to the first connecting member via a lock washer 306 and a lock nut 307. The output shaft of the second throttle driver 3012 is connected to the second throttle 3082 via a second connecting member. The second connecting member is preferably a cross-shaped mounting bracket with a mounting hole machined thereon. The output shaft of the second throttle driver is fixedly connected to the second connecting member via a lock washer 306 and a lock nut 307.

[0054] In one embodiment, a crushing member 309 is provided at the outlet of the throttle 308 to crush the material at the outlet of the throttle. The crushing member 309 is preferably a grid structure.

[0055] In one embodiment, a second sealing member 302 is provided at the inlet of the throttle 308. The second sealing member 302 is fixed to the rear end face of the assembled throttle to ensure the sealing of the throttle when it is in operation.

[0056] After the throttle 308 is connected, the left and right ends are fixed to the head of the throttle driver 301 by means of anti-loosening washers 306 and anti-loosening nuts 307 respectively. When the throttle driver is actuated according to demand, the throttle is driven to move accordingly: the inlet of the throttle 308 is away from the outlet of the auger feeding assembly, realizing the outlet discharge of the auger conveying assembly; the inlet of the throttle 308 is sealedly connected to the outlet of the auger feeding assembly, realizing the outlet discharge of the throttle.

[0057] In one embodiment, the auger feed mechanism further includes an auger drive assembly 101, disposed on the housing 400. The auger drive assembly is connected to the auger feed assembly via a first transmission mechanism. Specifically, the end of the housing 400 closest to the auger drive assembly 101 is defined as the "front end," and the end farther from the auger drive assembly 101 is defined as the "rear end." It should be understood that the "front end" and "rear end" used here are merely for convenience in illustrating the position of the auger feed mechanism in the diagram. As the position of the auger drive assembly 101 changes, the "front end" and "rear end" will also change accordingly. The auger drive assembly 101 is preferably a reduction motor.

[0058] The first sprocket 102 is fixed to the output shaft of the auger drive assembly 101 through a key connection, and the base of the auger drive assembly 101 is connected to the motor mounting base 103 through bolts.

[0059] In one embodiment, the first transmission mechanism is a sprocket transmission mechanism, including a first sprocket 102, a second sprocket 108, and a first chain. The first sprocket is arranged on the output shaft of the drive assembly, and the second sprocket is arranged at one end of the auger shaft of the auger feeding assembly; the chain is sleeved on the first sprocket and the second sprocket.

[0060] In one embodiment, the height between the auger drive assembly and the housing is adjustable, thereby adjusting the center-to-center distance between the first and second sprockets. The motor mount 103 is secured to the housing 400 via four adjustment bolts 104. The adjustment bolts 104 adjust the height of the motor mount 103 to facilitate adjustment of the sprocket center-to-center distance between the first sprocket 102 and the second sprocket 108.

[0061] In one embodiment, a stirring mechanism is provided on the feed port of the shell, and the stirring mechanism is connected to the auger feeding assembly via a second transmission mechanism. Specifically, the stirring mechanism 112 is installed above the auger assembly 200. In one embodiment, the stirring mechanism 112 is a horizontal structure. Specifically, the stirring structure includes a stirring shell, on which a horizontal stirring shaft 1122 is rotatably installed, and a stirring rod 1121 is provided on the stirring shaft. The left and right journals of the stirring shaft 1122 are installed below the feed port at the rear end of the shell 400 through a seat bearing 110. The seat bearing 110 can ensure that the stirring mechanism 112 rotates without jamming and moves smoothly. A third sprocket 111 is installed at the rear end of the stirring mechanism 112. The stirring mechanism 112 includes a stirring shaft 1122 and a stirring rod 1121. During the rotation process, the stirring mechanism 112 breaks up the material and drops it into the blades at the rear end of the auger assembly 200 for transportation, thereby ensuring uniform feeding.

[0062] In one embodiment, the second transmission mechanism is a sprocket transmission mechanism, including a third sprocket 111, a fourth sprocket 115, and a second chain. The third sprocket 111 is disposed on the stirring shaft 1122 of the stirring mechanism, and the fourth sprocket 115 is disposed on the other end of the auger shaft of the auger feeding assembly. The second chain is sleeved on the third sprocket 111 and the fourth sprocket 115.

[0063] In one embodiment, a tensioning assembly is provided on the housing for tensioning the second chain. The tensioning assembly includes a tensioning shaft assembly 114 and a tensioning sprocket 113. The tensioning shaft assembly 114 is bolted to the rear end of the housing 400, and the tensioning sprocket 113 is mounted to the rear end of the tensioning shaft assembly 114.

[0064] In one embodiment, the position of the tensioning assembly on the housing 400 is adjustable. Specifically, a waist-shaped hole is provided at the fixed end of the tensioning shaft assembly 114 to facilitate tensioning the second chain between the third sprocket 111 and the fourth sprocket 115 .

[0065] In one embodiment, the auger feeding mechanism further includes a control unit, which is connected to the throttle drive member and the auger drive assembly respectively.

[0066] The choke with grille features a hollow, split-half structure. A gasket ensures a tight seal at the connection, while the hollow section prevents contact between the auger shaft and the choke. The choke with grille is connected to the cylinder head via a locknut and lockwasher. The cylinder defaults to the ejected position, separating the choke from the auger tube. This allows for high-flow, rapid feeding with rapid auger rotation. When the target feed rate is nearing completion and slow feed is required to control overall feed accuracy, the control unit (instrument or PLC) triggers an electrical signal to the solenoid valve, switching the cylinder to the retracted position and reducing the auger feed speed. This allows the choke to maintain contact with the auger tube. As the material is fed into the choke through the auger, it becomes relatively compacted due to its decreasing cross-sectional area. A grating device embedded in the choke outlet further breaks up the compacted material, preventing it from clumping and causing inaccurate feed. This structure controls both the discharge flow rate and the uniformity of the discharge. This mechanism can achieve higher packaging or batching precision requirements and is a high-quality solution that takes into account both speed and precision. This mechanism also has the advantages of simple control, low cost, and easy installation and maintenance. It can be widely used in batching or packaging equipment with higher precision requirements.

[0067] Example 2

[0068] The material feed rate adjustment method is implemented using the auger feeding mechanism of any one of the embodiments 1, wherein the throttle driving member drives the throttle away from the outlet of the auger feeding assembly, and at the same time, the rotation speed of the auger assembly is increased, and the material is quickly spirally conveyed by the auger assembly and then flows directly into the outlet of the housing;

[0069] The throttle drive component drives the throttle close to and seals the outlet of the auger feeding assembly. At the same time, the rotation speed of the auger drive assembly is reduced, driving the auger assembly to rotate slowly to convey the material. The material is slowly spirally conveyed into the throttle by the auger assembly and flows out through the throttle outlet. The cross-sectional contraction of the throttle is used to control the material flow, and then flows into the outlet of the shell. Specifically:

[0070] like Figure 6 As shown, when the auger drive assembly 101 rotates, it drives the first sprocket 102. Thanks to the support of the seat bearing 106 and the chain drive, the auger assembly 107, the second sprocket 108, and the fourth sprocket 115 can all rotate on the auger tube axis of the housing 400. Similarly, thanks to the support of the seat bearing 110 and the chain drive, the stirring mechanism 112 can rotate accordingly. Material flows into the rear feed port of the housing 400, is agitated and broken by the stirring mechanism 112, and then evenly dispersed onto the rear blades of the auger assembly 200. The material is then squeezed and transported to the front discharge port by the rotation of the auger assembly 200.

[0071] like Figure 7As shown, when rapid feeding is required, the auger drive assembly 101 rotates at a high frequency to drive the auger assembly 200 to rotate rapidly. At this time, the throttle drive component 301 is in the ejection state, and the corresponding throttle 308 is separated from the end face of the shell 400 pipe wall. The material is quickly spirally conveyed by the auger assembly 200 and flows directly into the discharge port.

[0072] When slow feeding is required to ensure accuracy, the auger drive component 101 rotates at a low frequency to drive the auger component 200 to rotate slowly. At this time, the throttle drive component 301 moves to a contracted state, and the throttle 308 fits against the tube wall of the shell 400. The material is slowly spirally conveyed to the throttle 308 through the auger component 200. After the cross-sectional contraction effect of the throttle 308, the material flow is controlled. The grid device at the outlet of the throttle 308 can crush the compressed material again and flow it into the discharge port, so that the uniformity of the feed is guaranteed. Under the combined effect, the overall feeding accuracy can be effectively controlled.
