Description

Technical Field

[0001] This utility model relates to a packing mechanism, and more particularly to an anti-clogging packing mechanism. Background Technology

[0002] In the packing industry, such as chemical, food, pharmaceutical, and building materials sectors, various materials (e.g., powders, pastes, high-viscosity liquids) often need to be packaged. During the packing process, these materials are prone to adhesion, clumping, or accumulation in key parts of the packing machine, such as the storage cylinder, feed pipe, or filling nozzle, due to their inherent characteristics (e.g., easy solidification, oil content, high viscosity) or external conditions (e.g., temperature changes, improper flow rate control). This can lead to blockages in the filling channels. Blockages directly cause decreased filling efficiency, loss of filling accuracy, frequent production interruptions, significant material waste, and even damage to critical components due to equipment overload, increasing maintenance costs. For example, materials containing oils easily release oils under mechanical friction or temperature fluctuations, which then re-solidify at room temperature and adhere to the inner walls of the equipment.

[0003] Existing technologies attempt to alleviate blockage problems in several ways: First, mechanical unblocking devices are used, such as rotating unblocking rods or scrapers installed in the storage cylinder, which break up material bridging through eccentric motion or continuous rotation; second, mixing mechanisms (such as spiral blades or mixing rods) are used to maintain material flowability during the conveying process; and third, pneumatic assistance (such as compressed gas blowing) is used to reduce dust accumulation or improve the compactness of the packing.

[0004] However, these solutions still have obvious limitations: mechanical unblocking mechanisms are often designed for a single type of blockage and are poorly adaptable to changes in material properties (such as sudden changes in viscosity or differences in oil content); while pneumatic assistance can improve flow efficiency, it requires an additional air source and has limited effectiveness on high-viscosity materials; and simple stirring or scraping is difficult to completely remove the substances adhering to the inner wall, especially when the material is prone to solidification, the residue will continue to accumulate.

[0005] Patent publication number CN221738302U discloses an anti-clogging filling mechanism. Two rotating shafts drive multiple stirring blades and a stirring frame to stir the calcium powder, preventing it from accumulating inside the filling tank and causing blockage. A dual-end motor drives two threaded rods to rotate, moving two clamps to hold the filling tube and prevent the filling tank from shifting, thus preventing filling failure. However, this filling mechanism is suitable for dry calcium powder and other non-perishable powder materials. For materials that are crushed, release oil, and solidify at room temperature, it actually increases the risk of blockage. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies where materials that have broken down and solidified at room temperature are prone to clogging during the filling process. This invention provides an anti-clogging filling mechanism to reduce or avoid the adhesion, retention, and accumulation of materials in the conveying channel, thus preventing blockages. The filling material can be filled in 2 to 3 sections in a density-controlled manner within the filling container, ensuring continuous and stable filling operations, improving production efficiency, and allowing the filling mechanism to adapt to a wider range of materials.

[0007] The objective of this utility model can be achieved through the following technical solutions: A clog-resistant filling mechanism for filling material into a filling container, the filling mechanism comprising: Support frame; The lifting filler assembly includes a lifting slider disposed on the support frame and capable of moving up and down, a hopper mounted on the lifting slider, a discharge pipe connected to the bottom outlet of the hopper, and a material pusher rod passing through the hopper and the discharge pipe from above. The material pusher rod is capable of reciprocating in the vertical direction to push and squeeze the material poured into the hopper, so that the material is sent out through the discharge pipe. The tilting and pouring component located next to the lifting and filling assembly is used to tilt the material and pour it into the hopper; And a clamp assembly located below the discharge pipe for clamping and securing the filling container.

[0008] Furthermore, the support frame is provided with a first driving member that is connected to the lifting slider in a transmission manner, for driving the lifting slider to move along the vertical direction of the support frame; The first driving component is a servo motor.

[0009] Furthermore, a fixed frame is installed on the hopper, and a second driving component is installed on the fixed frame. The second driving component is connected to the material-push rod and drives the material-push rod to reciprocate in the vertical direction. The second driving component is a cylinder or a servo electric cylinder.

[0010] Furthermore, the hopper includes an upper hopper and a lower hopper connected vertically; The feeding hopper is provided with at least one intermediate partition, which divides the interior of the feeding hopper into multiple independent feeding channels; The bottom of the feeding hopper is equipped with a horizontally pull-out bottom plate to open or close the bottom outlets of multiple feeding channels in the feeding hopper.

[0011] Furthermore, the base plate is connected to the third driving component for transmission, driving the base plate to move horizontally; the third driving component is a cylinder or a servo electric cylinder.

[0012] Furthermore, the feeding hopper and the unloading hopper are cone-shaped.

[0013] Furthermore, the feeding hopper includes a fixed section and a movable section that is detachably connected to the fixed section, facilitating cleaning and maintenance.

[0014] Furthermore, the disassembly and connection method adopts conventional connections in the art, such as bolt connections.

[0015] Furthermore, the surface of the lifting packing assembly that comes into contact with the material is provided with an anti-stick coating.

[0016] Furthermore, the anti-stick coating includes fluorocarbon coatings, silicone coatings, ceramic coatings, nano-coatings, and coatings after electropolishing treatment. With the development of technology, even better anti-stick coatings can also be used.

[0017] Furthermore, a pneumatic vibrator is installed on the outer wall of the silo to generate periodic vibrations.

[0018] Furthermore, the pneumatic oscillator is driven by a vibrating cylinder to provide driving force.

[0019] Furthermore, the discharge pipe is detachably connected to the bottom of the hopper.

[0020] Furthermore, the discharge pipe is detachably connected to the bottom of the hopper via a clamp.

[0021] Furthermore, the tilting and unloading assembly includes: A weighing unit installed on the lifting slider and capable of quantitatively weighing materials; And a flipping unit that drives the weighing unit to flip back and forth. When the weighing unit is quantitatively filled with material, the flipping unit drives the weighing unit to flip toward the silo, so that all the material in the weighing unit can be poured into the silo.

[0022] Furthermore, the weighing unit includes: Weighing sensor; The weighing hopper, which is installed on the weighing sensor and can rotate to pour material, allows the weighing sensor to accurately detect the weight of the material when it is filled into the hopper.

[0023] Furthermore, the flipping unit includes: Rotary cylinder; A flipper connected to the rotary cylinder; A transmission lever is provided, with one end connected to the end of the flipping plate away from the rotary cylinder and the other end connected to the weighing hopper. When the rotary cylinder rotates, the flipping plate drives the transmission lever and the weighing hopper to flip synchronously.

[0024] Furthermore, the clip assembly includes: Finger cylinder; And two clamping plates connected to the finger cylinder. When the two clamping plates are driven to move closer to each other by the finger cylinder, a clamping cavity is formed between the two clamping plates that can cooperate with the discharge pipe to clamp the filling container.

[0025] Furthermore, when the clamping plates grip the filling container, the clamping force provided by the finger cylinder is adjustable. The clamping force is determined by the air pressure supplied to the finger cylinder, and specifically, the gas pressure entering the finger cylinder can be controlled by adjusting the air source pressure, thereby achieving adjustment of the output clamping force.

[0026] Furthermore, the filling mechanism also includes a top-loading assembly located directly below the filling container. The top-loading assembly includes a fourth drive member and a base, with the base disposed at the moving end of the fourth drive member.

[0027] Furthermore, the base is a cylinder head seat. Further, the loading container includes a conical paper roll and a cylindrical paper roll. A container base is also provided outside the loading container.

[0028] Furthermore, in some specific embodiments, the clamping cavity is divided into a straight cylindrical upper section and a conical lower section that is wider at the top and narrower at the bottom, with a smooth transition between the upper and lower sections. Preferably, the conical structure of the lower section is similar in shape to the paper roll, but slightly larger in size, to facilitate the continued downward movement of the paper roll during the filling process; while the straight cylindrical upper section can provide a larger clamping force-bearing area.

[0029] Compared with the prior art, the present invention has the following advantages: (1) This utility model constructs an active and efficient anti-clogging solution through the vertical reciprocating movement of the material-push rod. The material-push rod runs through the hopper and the discharge pipe from top to bottom. Its movement principle is similar to that of a piston. With the hopper divided, the flow rate is controlled after filling. The material can fall into the material pipe by the vibrator and the weight of the material itself, so that the material can be directly pushed and compacted. This utility model can fill the filling material in the filling container in multiple sections with controllable density. Compared with the rotary stirring rod, this reciprocating piercing motion has less shear force on the material, and is especially suitable for easily agglomerated powders and granules. Its movement trajectory is consistent with the direction of gravity flow of the material, which can more effectively break the vertically formed material arch and has no dead zone. More importantly, the material-push rod is controlled by an independent second drive component. It can be used with the lifting filling assembly to compact in the container, and can also automatically start high-frequency short-range motion when the material discharge is not smooth, so as to achieve precise and timely blockage intervention, from passive response to active prevention, which greatly improves the reliability and continuity of the filling.

[0030] (2) The feeding hopper of this utility model is divided into multiple independent feeding channels by a middle partition, which makes the material distribution more uniform and reduces the possibility of local accumulation; the horizontally pull-out bottom plate is controlled by a third drive component, which can quickly open and close the bottom of the channel, facilitating flow adjustment and cleaning maintenance. The conical shape of the hopper facilitates the natural sliding of materials by gravity, while the anti-stick coating significantly reduces the adhesion between the material and the metal surface, preventing the residue of grease or high-viscosity components. The periodic vibration generated by the pneumatic oscillator further breaks the static friction of the material, maintaining its fluidity. These elements, combined with the detachable connection, make the equipment easy to clean and adapt to changes in material characteristics, thereby extending its service life and reducing maintenance frequency and cost.

[0031] (3) The overall system of this utility model integrates a tilting and pouring component and a clamping component, realizing full automation and high adaptability of the filling process. The tilting and pouring component accurately measures the material through a weighing unit and controls the pouring angle by a tilting unit, ensuring that the material is poured into the hopper intact, avoiding errors or spillage caused by manual operation. The clamping component uses a finger cylinder with adjustable clamping force, which can firmly fix filling containers of different shapes (such as conical paper rolls) to prevent filling failure or material waste caused by container displacement. This integrated design enables the mechanism to flexibly cope with various material profiles and production conditions, improving the stability of continuous operation. Compared with existing solutions that rely on a single anti-clogging technology, this utility model significantly improves production efficiency and equipment reliability through the synergy of mechanical, pneumatic and structural optimization.

When the weighing unit 31 is quantitatively filled with material, the flipping unit 32 drives the weighing unit 31 to flip toward the hopper 22, so that all the material in the weighing unit 31 can be poured into the hopper 22.

[0089] In this embodiment, the weighing unit 31 includes: Weighing sensor 311; The weighing hopper 312, which is installed on the weighing sensor 311 and can rotate to pour material, can accurately detect the weight of the material when the material is filled into the weighing hopper 312.

[0090] In this embodiment, the flipping unit 32 includes: Rotary cylinder 321; A flipper 322 connected to the rotary cylinder 321; And a transmission lever 323, one end of which is connected to the end of the flipping plate 322 away from the rotary cylinder 321 and the other end of which is connected to the weighing hopper 312, when the rotary cylinder 321 rotates, the flipping plate 322 drives the transmission lever 323 and the weighing hopper 312 to flip synchronously.

[0091] In this embodiment, the clip assembly 4 includes: Finger cylinder 41; And two clamping plates 42 connected to the finger cylinder 41. When the two clamping plates 42 are driven to move closer to each other by the finger cylinder 41, a clamping cavity is formed between the two clamping plates 42 that can cooperate with the discharge pipe 23 to clamp the loading container 6.

[0092] In this embodiment, when the clamping piece 42 clamps the filling container 6, the clamping force provided by the finger cylinder 41 is adjustable. Specifically, the gas pressure entering the finger cylinder 41 can be controlled by adjusting the air source pressure, thereby adjusting the output clamping force.

[0093] In this embodiment, the loading container 6 is a conical paper roll. A paper roll base is also provided outside the conical paper roll.

[0094] In this embodiment, the clamping cavity is divided into a straight cylindrical upper section and a conical lower section that is wider at the top and narrower at the bottom, with a smooth transition between the upper and lower sections. The conical structure of the lower section is similar in shape to the conical paper roll 11, but slightly larger, which facilitates the continued downward movement of the conical paper roll 5 during the filling process; while the straight cylindrical upper section can provide a larger clamping force area.

[0095] Example 3 An anti-clogging filling mechanism is used to fill material into the filling container 6, such as... Figures 1-2 As shown, the packing mechanism includes: Support frame 1; The lifting filler assembly 2 includes a lifting slider 21 that is mounted on the support frame 1 and can move up and down, a hopper 22 mounted on the lifting slider 21, a discharge pipe 23 connected to the bottom outlet of the hopper 22, and a material pusher 24 that passes through the hopper 22 and the discharge pipe 23 from above. The material pusher 24 can reciprocate in the vertical direction to push and squeeze the material poured into the hopper 22, so that the material is sent out through the discharge pipe 23. The tilting and pouring component 3, located next to the lifting and filling component 2, is used to tilt the material and pour it into the hopper 22; And a clamp assembly 4 located below the discharge pipe 23 for clamping and fixing the filling container 6.

[0096] In this embodiment, the support frame 1 is provided with a first driving member 25 that is connected to the lifting slider 21 for driving the lifting slider 21 to move in the vertical direction of the support frame 1; the first driving member 25 is a servo motor.

[0097] In this embodiment, a fixing frame 26 is installed on the hopper 22, and a second driving member 27 is installed on the fixing frame 26. The second driving member 27 is connected to the material feeding rod 24 and drives the material feeding rod 24 to reciprocate in the vertical direction. The second driving member 27 is a cylinder.

[0098] In this embodiment, as Figure 3 As shown, the hopper 22 includes an upper hopper 221 and a lower hopper 222 connected vertically. The feeding hopper 221 is provided with a middle partition 223, which divides the interior of the feeding hopper 221 into two independent feeding channels. The bottom of the feeding hopper 221 is provided with a horizontally pull-out bottom plate 224 to open or close the bottom outlets of multiple feeding channels in the feeding hopper 221.

[0099] In this embodiment, the intermediate partition 223 is a T-shaped partition, including a first plate 2231 and a second plate 2232 arranged vertically. The first plate 2231 is parallel to the pulling direction of the bottom plate 224, and the second plate 2232 is perpendicular to the pulling direction of the bottom plate 224. The height of the first plate 2231 is greater than that of the second plate 2232. The first plate 2231 divides the material in the feeding hopper 221 into two spaces. The first plate 2231 is located on one side of the feeding rod 24, and the material is poured in from the side that does not pass through the feeding rod 24. In the feeding hopper 221, the material does not contact the feeding rod. The second plate 2232 divides the space where the material is poured into into two independent feeding channels of equal size, named the first feeding channel and the second feeding channel.

[0100] In this embodiment, the base plate 224 is connected to the third driving member 225, driving the base plate 224 to move horizontally; the third driving member 225 is a cylinder. The second feeding channel is located near the third driving member 225, and the other is the first feeding channel.

[0101] In this embodiment, when the third driving member 225 drives the base plate 224 to the maximum stroke position (located at the bottom of the feeding bin 221), it is located below the second feeding channel 2233, completely blocking the second feeding channel 2233.

[0102] In this embodiment, a vertical plate 226 is also connected to the side of the bottom plate 224. The vertical plate 226 is located below the first plate 2231 of the intermediate partition 223 and is used to prevent materials from falling from the second feeding channel.

[0103] In this embodiment, the feeding bin 221 and the unloading bin 222 are cone-shaped.

[0104] In this embodiment, the feeding hopper 221 includes a fixed hopper section 2211 and a movable hopper section 2212 that is detachably connected to the fixed hopper section 2211, which facilitates cleaning and maintenance.

[0105] In this embodiment, the disassembly and connection method adopts a conventional connection in the art, such as a bolt connection.

[0106] In this embodiment, the surfaces of the lifting packing assembly 2 that come into contact with the material are provided with an anti-stick coating, which is a Teflon coating. The surfaces of the lifting packing assembly 2 that come into contact with the material include the inner wall of the hopper 22, the material feeding rod 24, and the discharge pipe 23.

[0107] In this embodiment, a pneumatic vibrator 28 is installed on the outer wall of the hopper 22 to generate periodic vibrations. The pneumatic vibrator 28 is driven by a vibration cylinder 29, which provides the driving force. The pneumatic vibrator 28 is located at the connection between the upper hopper 221 and the lower hopper 222, ensuring that both the upper hopper 221 and the lower hopper 222 achieve effective vibration.

[0108] In this embodiment, the discharge pipe 23 is detachably connected to the bottom of the hopper 22, and the discharge pipe 23 is detachably connected to the bottom of the hopper 22 by a clamp.

[0109] In this embodiment, the flipping and unloading component 3 includes: A weighing unit 31 installed on the lifting slider 21 and having the ability to weigh materials quantitatively; And a flipping unit 32 that drives the weighing unit 31 to flip back and forth. When the weighing unit 31 is quantitatively filled with material, the flipping unit 32 drives the weighing unit 31 to flip toward the hopper 22, so that all the material in the weighing unit 31 can be poured into the hopper 22.

[0110] In this embodiment, the weighing unit 31 includes: Weighing sensor 311; The weighing hopper 312, which is installed on the weighing sensor 311 and can rotate to pour material, can accurately detect the weight of the material when the material is filled into the weighing hopper 312.

[0111] In this embodiment, the flipping unit 32 includes: Rotary cylinder 321; A flipper 322 connected to the rotary cylinder 321; And a transmission lever 323, one end of which is connected to the end of the flipping plate 322 away from the rotary cylinder 321 and the other end of which is connected to the weighing hopper 312, when the rotary cylinder 321 rotates, the flipping plate 322 drives the transmission lever 323 and the weighing hopper 312 to flip synchronously.

[0112] In this embodiment, the clip assembly 4 includes: Finger cylinder 41; And two clamping plates 42 connected to the finger cylinder 41. When the two clamping plates 42 are driven to move closer to each other by the finger cylinder 41, a clamping cavity is formed between the two clamping plates 42 that can cooperate with the discharge pipe 23 to clamp the loading container 6.

[0113] In this embodiment, when the clamping piece 42 clamps the filling container 6, the clamping force provided by the finger cylinder 41 is adjustable. Specifically, the gas pressure entering the finger cylinder 41 can be controlled by adjusting the air source pressure, thereby adjusting the output clamping force.

[0114] In this embodiment, the filling mechanism further includes a top-loading assembly 5 located directly below the filling container 6. The top-loading assembly 5 includes a fourth drive member 51 and a base 52. The base 52 is disposed at the moving end of the fourth drive member 51. The fourth drive member 51 is a double-stroke cylinder configured to drive the base 52 to have at least two stop positions to selectively abut or lift the filling container 6. The base 52 is a cylinder head seat.

[0115] In this embodiment, the dual-stroke cylinder is a nested cylinder, including a mother cylinder and a daughter cylinder disposed within the cavity of the mother piston rod of the mother cylinder. The mother cylinder drives the mother piston rod to achieve a first lifting stroke, and the daughter cylinder drives the daughter piston rod to achieve a second lifting stroke. The daughter piston rod is directly or indirectly connected to the base 52. The first lifting stroke is configured to move the base 52 to a stop position contacting the bottom of the filling container 6, and the second lifting stroke is configured to move the base 52 to a lifting position that lifts the filling container 6 upwards.

[0116] In this embodiment, the loading container 6 is a conical paper roll. A paper roll base is also provided outside the conical paper roll.

[0117] In this embodiment, the clamping cavity is divided into a straight cylindrical upper section and a conical lower section that is wider at the top and narrower at the bottom, with a smooth transition between the upper and lower sections. The conical structure of the lower section is similar in shape to the conical paper roll 11, but slightly larger, which facilitates the continued downward movement of the conical paper roll during the filling process; while the straight cylindrical upper section can provide a larger clamping force-bearing area.

[0118] In this embodiment, the operation process of the anti-clogging packing mechanism is as follows: An operator or robotic arm places an empty conical paper roll (filling container 6) into the container base 61 (in this embodiment, a paper roll base). Due to the diameter limitation of the paper roll base, the filling container 6 is positioned some distance above the base 52 of the top feeding assembly 5, aligning the opening of the paper roll with the upper discharge pipe 23. The double-stroke cylinder 51 of the top feeding assembly 5 drives the base 52 to rise to the first lifting stroke, causing the conical paper roll to move upward and align with the lower end of the discharge pipe 23, slightly abutting it to ensure a tight seal. The double-stroke cylinder 51 of the top feeding assembly 5 drives the base 52 to rise to the second lifting stroke, until the lower end of the discharge pipe 23 extends into the opening of the conical paper roll to a suitable depth, preparing for filling. The finger cylinder 41 actuates, driving the two clamping plates 42 to move closer together. The clamping cavity formed on the inner side of the clamping plates, adapted to the shape of the conical paper roll, can firmly and gently hold the paper roll, preventing it from shifting or tipping over during filling. By adjusting the air source pressure, the clamping force can be precisely controlled, ensuring stability while preventing damage to the conical paper roll. The double-stroke cylinder 51 of the top material assembly 5 drives the base 52 to reset, and the double-stroke cylinder 51 of the top material assembly 5 drives the base 52 to rise to the first lifting stroke.

[0119] Materials such as powders and granules are conveyed into the weighing hopper 312. The weighing sensor 311 monitors the material weight in real time, stopping feeding when a preset quantitative value is reached. The rotary cylinder 321 is activated, causing the weighing hopper 312 to tilt upwards towards the upper hopper 221 via the tilting plate 322 and the transmission lever 323. The tilting angle is designed to ensure that all material in the weighing hopper is completely and thoroughly poured into the upper hopper 221, guaranteeing the accuracy of the filling filler weight.

[0120] At this time, the bottom plate 224 of the feeding hopper 221 is in the closed position. Its initial position only blocks the second feeding channel, while the first feeding channel is open. The poured material first falls into the feeding hopper 221. The first plate 2231 divides the hopper space in two, and its main function is to guide the material to be poured in from the side of the feeding rod 24, avoiding direct impact and encapsulation of the feeding rod by the material, and reducing the movement resistance and initial adhesion of the feeding rod. The second plate 2232 further divides the space on the pouring side into the first feeding channel and the second feeding channel. By splitting the large flow of material into two smaller flows, the risk of material accumulation and bridging at the inlet is effectively reduced.

[0121] The material first flows into the feeding hopper 222 through the open first feeding channel for initial filling. All surfaces in contact with the material, including the hopper 22 and the feeding rod 24, are coated with a Teflon anti-stick coating, greatly reducing the material's adhesion tendency. A pneumatic vibrator 28, installed on the outer wall of the hopper 22, generates high-frequency, low-amplitude mechanical vibrations driven by a vibrating cylinder 29. This vibration is transmitted to the hopper wall, effectively breaking down the arched structures formed between material particles, keeping them loose and flowing, allowing them to move smoothly downwards. After the material is filled into the conical paper roll, the second driving component 27 drives the feeding rod 24 downwards (it can be repeatedly moved up and down within the loading container 6 if necessary), pushing the material in the conical paper roll downwards. This causes the conical paper roll to move slightly downwards. The finger cylinder 41 actuates, driving the two clamping plates 42 to move away from each other. The conical paper roll is released, and at this time, it falls onto the base 52 located at the first lifting stroke and is held in place. The servo motor 25 is activated, causing the discharge pipe 23 to move upwards by a certain position (the amount of movement is adjustable). The finger cylinder 41 is activated again, driving the two clamping plates 42 to move closer together and clamp the conical roll of paper. The double-stroke cylinder 51 of the top material assembly 5 drives the base 52 to reset. When it is necessary to increase the feeding amount or the feeding of the first feeding channel slows down, the third drive component 225 is activated, horizontally pulling the bottom plate 224. When the bottom plate 224 moves, the vertical plate 226 on its side moves accordingly. The vertical plate 226 is located below the first plate 2231, and its function is to ensure that when the bottom plate opens the second feeding channel, the material in the first feeding channel will not leak from the side. This allows the two feeding channels to work independently or in concert, and the feeding flow rate is controllable. When the bottom plate 224 is completely removed, the second filling is performed. After the second filling is completed, the second drive component 27 is driven to drive the shoveling rod 24 downwards (it can be moved up and down repeatedly in the loading container 6 if necessary) to shove the material in the loading container 6.

[0122] After filling is complete, the feeding rod 24 stops moving and returns to its original position, and the pneumatic vibrator 28 stops vibrating. The bottom plate 224 resets under the drive of the cylinder, closing the bottom outlet of the feeding hopper 221. The first driving component 25 drives the lifting filling assembly 2 to rise as a whole, causing the discharge pipe 23 to detach from the filled paper roll. The finger cylinder 41 is released, and the operator or robot arm removes the paper roll filled with material. The flipping unit 32 drives the weighing hopper 312 to flip and reset, ready for the next quantitative weighing. Because the feeding hopper is designed with a detachable movable section 2212, and the discharge pipe 23 is detachably connected to the hopper via a clamp, regular cleaning and maintenance become very convenient.

[0123] When material blockage occurs in the discharge hopper 222, the second drive component 27 can drive the piercing rod 24 to perform a high-speed, short-range reciprocating piercing motion. The piercing rod 24 is like a giant needle, passing through the blocked material area from top to bottom.

[0124] Example 4 Compared with Embodiment 3, most of them are the same, except that the second drive component 27 and the third drive component 225 in this embodiment are both servo electric cylinders.

[0125] In this embodiment, the second driving component 27 is a servo electric cylinder. The cylinder body of the servo electric cylinder is fixedly mounted on the fixed frame 26, and its push rod is drivenly connected to the top end of the material-push rod 24. The reciprocating frequency, stroke, and speed of the material-push rod 24 can be precisely set.

[0126] In this embodiment, the third driving component 225 is a servo electric cylinder. The push rod of the servo electric cylinder is connected to the bottom plate 224 of the feeding bin 221 for precise control of the pulling stroke and opening degree of the bottom plate. This makes the feeding control of the two feeding channels no longer a simple "open" or "close" operation, but allows for precise adjustment of the opening degree, thereby achieving precise control of the feeding flow rate and meeting more refined filling process requirements. At this time, the maximum stroke of the bottom plate 224 is no longer limited to being located below the second feeding channel 2233, but can be located below the first and second feeding channels, simultaneously blocking the bottom openings of both feeding channels, and then achieving precise opening degree adjustment.
