Abstract
Description
Technical Field
[0001] This invention relates to the field of building ceramics technology, and in particular to a feeding machine and a feeding control method. Background Technology
[0002] In the production process of architectural ceramics, ball milling is a core step in the preparation of raw materials and glazes. In the preparation of the raw material slurry, ball milling mainly involves mixing and grinding raw materials, including clay and sand, according to the formula ratio. Sand, due to its good particle flowability, is less prone to clogging when fed through the feeder. However, clay, due to its inherent high viscosity and tendency to agglomerate, is highly susceptible to bridging during feeding and distribution.
[0003] Specifically, due to its own adhesion and cohesive forces, mud in storage silos or feeding equipment often forms stable material arches above the discharge port, causing material flow interruptions or even complete blockage of the feeder. This problem is persistent and unpredictable, not an occasional malfunction, but a frequent occurrence in the production process. Once bridging occurs, the current solution requires operators to manually tap, poke, or clear the bridging with tools to temporarily restore feeding. This approach is not only inefficient, disrupting production continuity and forcing the ball mill and subsequent processes to frequently operate in a waiting or under-load state, but also significantly increases the labor intensity and safety risks for operators. Summary of the Invention

The n actuators are connected and rotated sequentially. When two extrusion components move relative to each other, the n actuators swing synchronously, and the connection point between the two actuators reciprocates along the height direction of the feeding body.
[0006] Optionally, the actuator is connected to the pressing member via a revolute joint; In the height direction of the feeding body, the rotary joint is located above the connection point between the two actuators.
[0007] Optionally, the anti-bridging mechanism further includes: A linear drive device is mounted on the feeding body, the output end of the linear drive device is connected to the extrusion member, and the linear drive device is configured to drive the extrusion member to move.
[0008] Optionally, a feeding channel is provided inside the feeding body. The cross-sectional area of the feeding channel gradually decreases from top to bottom along the height direction of the feeding body. An inlet is provided at the upper end of the feeding body, and an outlet is provided at the lower end of the feeding body. Both the inlet and the outlet are connected to the feeding channel.
[0009] Optionally, both extrusion members are arranged at an angle from top to bottom toward the centerline of the feeding body along the height direction of the feeding body, so that the gap between the two extrusion members forms a wedge-shaped gap that is wider at the top and narrower at the bottom.
[0010] Optionally, the feeder further includes: A screw conveyor mechanism, comprising: Drive motor; A spiral reamer, which passes through the wedge-shaped gap to be mounted within the feeding body; The spiral reamer includes a rod and a spiral blade disposed on the surface of the rod and extending along the axial direction of the rod; The output end of the drive motor is connected to one end of the spiral reamer. When the drive motor drives the spiral reamer to rotate, the spiral blades rotate the material in the feeding channel through the discharge port.
[0011] Optionally, a conveying mechanism is provided below the feeding body, the conveying mechanism including: The mounting bracket is equipped with two pulleys. A conveyor belt, which is wound around the two pulleys and is located directly below the discharge port.
[0012] Optionally, the extrusion member includes a bottom wall and a plurality of side walls extending from the edge of the bottom wall, the bottom wall and the plurality of side walls together defining a receiving groove with an opening; The feeding body is provided with a fixed frame and a suspension plate. The suspension plate is disposed in the receiving groove and is connected to the feeding body through the fixed frame.
[0013] Optionally, the extruded member is made of polyethylene material.
[0014] In addition, this application also provides a feeding control method for the feeder as described above, including: Start the feeder to make the anti-bridging mechanism workable; Material is conveyed into the feeding body; Control the two extrusion components to move towards each other, extruding the material toward the middle area of the feeding body; During the movement of the extrusion component, the linkage drives n sequentially rotated and connected actuators to swing synchronously. The connection point between two adjacent actuators reciprocates along the height direction of the feeding body to complete the material arch breaking operation.
[0015] Beneficial Effects: The feeder proposed in this invention includes a feeding body and an anti-bridging mechanism. The feeding body has two opposing movable slots, and the anti-bridging mechanism is located on the feeding body. The anti-bridging mechanism includes two opposing extrusion members and at least one anti-bridging actuator. The two opposing extrusion members are movably installed in the two movable slots and can move towards or away from each other. The anti-bridging actuator is located between the two extrusion members and includes n actuators, where n is a natural number greater than or equal to 2. The n actuators are sequentially rotatably connected. When the two extrusion members move relative to each other, the n actuators swing synchronously, and the connection point between the two actuators reciprocates along the height direction of the feeding body. This design allows the two extrusion members to periodically extrude the material through relative displacement, thereby achieving vibratory feeding while simultaneously disrupting the static adhesion tendency of the material and inhibiting the formation of material bridging. When the two extrusion components move relative to each other, the driving force is converted into the oscillating motion of n actuators through the rotating connection point. This causes the connection point of the two actuators to reciprocate along the height direction of the feeding body, thereby creating a vertical dispersing effect on the material, preventing material bridging, effectively solving the problem of material bridging during the feeding process, ensuring the continuity of material feeding, improving feeding efficiency, and thus reducing production costs.

[0024] In the production process of architectural ceramics, ball milling is a core step in the preparation of raw materials and glazes. In the preparation of the raw material slurry, ball milling mainly involves mixing and grinding raw materials, including clay and sand, according to the formula ratio. Sand, due to its good particle flowability, is less prone to clogging when fed through the feeder. However, clay, due to its inherent high viscosity and tendency to agglomerate, is highly susceptible to bridging during feeding and distribution.
[0025] Specifically, due to its own adhesion and cohesive forces, mud in storage silos or feeding equipment often forms stable material arches above the discharge port, causing material flow interruptions or even complete blockage of the feeder. This problem is persistent and unpredictable, not an occasional malfunction, but a frequent occurrence in the production process. Once bridging occurs, the current solution requires operators to manually tap, poke, or clear the bridging with tools to temporarily restore feeding. This approach is not only inefficient, disrupting production continuity and forcing the ball mill and subsequent processes to frequently operate in a waiting or under-load state, but also significantly increases the labor intensity and safety risks for operators.
[0026] Based on this, the present application provides a feeder, see [link to relevant documentation]. Figures 1-6 As shown, the feeder includes a frame 1, a feeding body 2, an anti-bridging mechanism 3, and a conveying mechanism 4. Sensor components 8 are installed at the four corners of the upper end of the frame 1. The four sensor components 8 fix the feeding body 2 on the frame 1.
[0027] Specifically, the sensing assembly 8 includes a sensor 81 mounted on the frame 1 and a fixing plate 82. The fixing plate 82 is positioned above the sensor 81, and a rigid connection is formed between the fixing plate 82 and the feeding body 2.
[0028] In this embodiment, sensor 81 can be a gravity sensor. The gravity sensor can continuously monitor the force state of the feeding body 2 at the four corner support points. By collecting load data in real time, the weight of the feeding body 2 can be detected. When the weight data collected by the gravity sensor reaches or exceeds the set threshold, an early warning mechanism is triggered, an early warning signal is generated and transmitted to the control terminal, so as to inform the staff that there is a risk of material blockage inside the feeding body 2, so that the staff can intervene in time.
[0029] In this embodiment, the inner cavity of the feeding body 2 forms a feeding channel 21 for the material to flow from top to bottom. The feeding body 2 is provided with two oppositely arranged movable grooves. The movable grooves extend along the height direction of the feeding body 2, and the groove opening size is adapted to the overall size of the anti-bridging mechanism 3.
[0030] Specifically, the anti-bridging mechanism 3 is installed on the feeding body 2. The anti-bridging mechanism 3 includes two opposing extrusion members 31 and at least one arch-breaking execution component 32. The two extrusion members 31 are respectively movably installed in the two movable slots, and the two extrusion members 31 can move relative to each other to approach or move away from each other.
[0031] The arch-breaking actuator 32 is disposed between the two extrusion members 31. One end of the arch-breaking actuator 32 is movably connected to one of the two extrusion members 31, and the other end of the arch-breaking actuator 32 is movably connected to the other of the two extrusion members 31.
[0032] In this application, the arch-breaking execution component 32 includes n execution elements 321, where n is a natural number greater than or equal to 2. The n execution elements 321 are connected in sequence and rotate. When the two extrusion components 31 move relative to each other, the n execution elements 321 swing synchronously, and the connection point between the two execution elements 321 reciprocates along the height direction of the feeding body 2.
[0033] In this embodiment, there are two actuators 321, which are rotatably connected. This design allows the two actuators 321 to cooperate to form a scissor structure that can swing relative to each other.
[0034] Of course, the number of actuators 321 is not limited to the two listed in this embodiment. In other embodiments of this application, the number of actuators 321 can be three, four, five, six or even more. Multiple actuators 321 are rotated and connected in sequence to be arranged between two extrusion members 31.
[0035] When the feeder is started, the material in the feeding body 2 flows downward along the feeding channel 21. At the same time, the anti-bridging mechanism 3 is started synchronously, and the two extrusion components 31 reciprocate relative to each other. When the two extrusion components 31 approach each other, the extrusion components 31 exert a squeezing effect on the accumulated material in the feeding channel 21, reducing the gap between the two extrusion components 31. Subsequently, the two extrusion components 31 move in opposite directions, the squeezing effect is released, and the material loosens under the action of gravity. Through the periodic squeezing action on the material, the static adhesion tendency of the material is destroyed.
[0036] During the relative movement of the two extrusion components 31, the two extrusion components 31 drive the two actuators 321 to reciprocate around the rotation connection point. When the two extrusion components 31 approach each other, the two actuators 321 swing towards each other, and the rotation connection point of the two actuators 321 moves downward along the height direction of the feeding body 2, forming a downward extrusion effect on the material accumulated below; when the two extrusion components 31 move away from each other, the two actuators 321 swing away from each other, and the rotation connection point of the two actuators 321 moves upward along the height direction of the feeding body 2, forming an upward lifting effect on the material. Through the periodic lifting and pressing operation of the material in the vertical direction, the two actuators 321 act on the material accumulation area that is prone to bridging, preventing the formation of material bridging, so that the material in the feeding channel 21 is in a dynamic loose state, avoiding the adhesion and bridging phenomenon formed by the material due to long-term static or slow flow, and ensuring that the material is continuously and stably fed along the feeding channel 21 of the feeding body 2.
[0037] The feeder provided in this embodiment of the application uses two extrusion components 31 to periodically extrude materials through relative displacement. This achieves vibratory feeding while simultaneously disrupting the static adhesion tendency of the materials and inhibiting the formation of material bridging. When the two extrusion components 31 move relative to each other, the driving force is converted into the oscillating motion of n actuators 321 through the rotating connection point. This causes the connection point of the two actuators 321 to reciprocate along the height direction of the feeding body 2, thereby creating a vertical dispersing effect on the materials and preventing material bridging. This effectively solves the problem of material bridging during feeding, ensures the continuity of material feeding, improves feeding efficiency, and ultimately reduces production costs.
[0038] In this embodiment, the actuator 321 is connected to the extrusion member 31 via a rotating joint 322. In the height direction of the feeding body 2, the rotating joint 322 is located above the connection point between the two actuators 321.
[0039] Specifically, the rotary joint 322 is a rotating shaft, and the extrusion member 31 is provided with two oppositely arranged lugs 314. Both oppositely arranged lugs 314 are provided with through holes. The rotary joint 322 passes through the through holes of the lugs 314 and is threadedly connected to the first fixing nut 323. This design allows the linear reciprocating motion of the extrusion member 31 to be transmitted to the actuator 321, so as to drive the two actuators 321 to reciprocate synchronously around their respective hinge points. When the two extrusion members 31 approach each other, the two actuators 321 swing synchronously towards each other, and their hinge nodes move downward along the height direction of the feeding body 2, forming a vertical downward pressing action on the material piled below, further loosening the material while preventing material bridging; when the two extrusion members 31 move away from each other, the two actuators 321 swing synchronously towards each other, and their hinge nodes move upward along the height direction of the feeding body 2, forming a vertical upward lifting action on the material above, thereby ensuring that the material in the feeding channel 21 is always in a dynamic loose state, avoiding the risk of adhesion and bridging caused by the material being static or flowing too slowly, and ensuring that the material is continuously and stably fed along the feeding channel 21.
[0040] In this embodiment, the anti-bridging mechanism 3 further includes a linear drive device 33, which is mounted on the feeding body 2. The output end of the linear drive device 33 is connected to the extrusion member 31, and the linear drive device 33 is configured to drive the extrusion member 31 to move.
[0041] Specifically, the linear drive device 33 provides a controllable linear drive force to the extrusion member 31 to drive the extrusion member 31 to reciprocate, thereby ensuring the stability of the linkage between the extrusion member 31 and the arch-breaking execution component 32.
[0042] The linear drive device 33 can be a cylinder, hydraulic cylinder, electric push rod, etc., to adapt to the driving force requirements and motion accuracy requirements under different working conditions.
[0043] In this embodiment, the cross-sectional area of the feeding channel 21 gradually decreases from top to bottom along the height direction of the feeding body 2. The upper end of the feeding body 2 is provided with an inlet 22, and the lower end of the feeding body 2 is provided with an outlet 23. Both the inlet 22 and the outlet 23 are connected to the feeding channel 21.
[0044] Specifically, the feeding body 2 has an inlet 22 and an outlet 23 respectively at its two axial ends. The inlet 22 is located in the upper region of the feeding body 2 and is used to receive the material being transported. The cross-sectional dimensions of the inlet 22 are matched with the cross-sectional dimensions of the upper end of the feeding channel 21 to ensure smooth material input. The outlet 23 is located in the lower region of the feeding body 2 and serves as the material output port. Its cross-sectional dimensions are matched with the cross-sectional dimensions of the lower end of the feeding channel 21 to achieve directional material output.
[0045] Both extrusion members 31 are arranged at an angle from top to bottom toward the center line of the feeding body 2, so that the gap between the two extrusion members 31 forms a wedge-shaped gap that is wider at the top and narrower at the bottom.
[0046] Specifically, when the two extrusion members 31 approach each other, the wider gap at the top can accommodate more of the accumulated material to be processed, reducing the risk of overflow caused by the material being squeezed at the inlet of the feeding channel 21. As the material flows downward under the action of gravity, the wedge-shaped gap gradually narrows. This design ensures both effective reception and initial compression of the loose material at the top, and high-intensity compression of the material that has already begun to accumulate at the bottom, pushing the material towards the middle of the feeding channel 21. When the extrusion members 31 move in opposite directions and the extrusion action is released, the material loosens under the combined action of gravity and gap expansion. The material at the top exerts a downward thrust on the material at the bottom through its gravity, propelling the loose material at the bottom through the feeding channel 21 quickly.
[0047] In this embodiment, the feeder also includes a screw conveyor mechanism 5, which includes a drive motor and a screw reamer 51. The screw reamer 51 passes through a wedge-shaped gap to be mounted inside the feed body 2.
[0048] The spiral reamer 51 includes a rod 511 and a spiral blade 512 disposed on the surface of the rod 511 and extending along the axial direction of the rod 511. The output end of the drive motor is connected to one end of the spiral reamer 51. When the drive motor drives the spiral reamer 51 to rotate, the spiral blade 512 spins the material in the feeding channel 21 out through the discharge port 23.
[0049] See Figure 2 As shown, a conveying mechanism 4 is provided below the feeding body 2. The conveying mechanism 4 includes a mounting bracket 41 and a conveyor belt 43. Two pulleys 42 are provided on the mounting bracket 41. The conveyor belt 43 is wound around the two pulleys 42 and is located directly below the discharge port 23.
[0050] Specifically, the two pulleys 42 are arranged at intervals along the preset conveying direction, and the axis lines of the two pulleys 42 are kept parallel to ensure that the conveyor belt 43 can be smoothly wound.
[0051] In this embodiment, the surface of the pulley 42 is treated with an anti-slip coating to increase the friction between the pulley 42 and the conveyor belt 43, preventing the conveyor belt 43 from slipping during operation and ensuring the stability of power transmission. The conveyor belt 43 is wound around the outer periphery of the two pulleys 42 in a tensioned state. By rotating the pulleys 42, the conveyor belt 43 is driven to circulate in a preset direction, thereby realizing the continuous transfer of materials.
[0052] In one embodiment of this application, the extrusion member 31 includes a bottom wall 311 and a plurality of side walls 312 extending from the edge of the bottom wall 311, the bottom wall 311 and the plurality of side walls 312 together defining a receiving groove 313 with an opening. The feeding body 2 is provided with a fixed frame 6 and a suspension plate 7. The suspension plate 7 is set in the receiving groove 313. The suspension plate 7 is connected to the feeding body 2 through the fixed frame 6. The output end of the linear drive device 33 passes through the suspension plate 7 and is connected to the extrusion member 31 through the second fixing nut 324.
[0053] When the suspension plate 7 is placed inside the receiving groove 313, the receiving groove 313 and the suspension plate 7 cooperate to form a multi-directional limit on the extrusion member 31, which limits the movement trajectory of the extrusion member 31. During the process of the linear drive device 33 driving the extrusion member 31 to move, it can prevent the extrusion member 31 from causing instability such as lateral displacement or torsion.
[0054] By adopting the above structural design, it works in coordination with the driving direction of the linear drive device 33, so that the displacement of the extrusion member 31 always follows the preset trajectory, thereby improving the stability of the movement of the extrusion member 31.
[0055] Secondly, the weight of the extrusion component 31 is transmitted through the bottom wall 311 and side wall 312 to the contact surface between the receiving groove 313 and the suspension plate 7, and then transmitted from the suspension plate 7 to the frame 1 via the fixing frame 6. In this process, the frame 1, as the load-bearing foundation, bears most of the weight load of the extrusion component 31, avoiding the direct action of the weight of the extrusion component 31 on the output end of the linear drive device 33. This ensures that the output end of the linear drive device 33 mainly bears the driving force required to drive the extrusion component 31 to produce linear displacement, rather than the weight load of the extrusion component 31. This reduces the load pressure on the linear drive device 33, which not only helps to improve the operating stability of the linear drive device 33, but also reduces the impact of the weight load on the output accuracy and transmission efficiency of the linear drive device 33, and extends the service life of the linear drive device 33.
[0056] Because polyethylene has an anti-sticking effect, the extrusion member 31 in this embodiment is made of polyethylene.
[0057] See Figure 7As shown, this application also provides a feeding control method for a feeder as described above, specifically including the following steps: S1. Start the feeder to make the anti-bridging mechanism 3 workable. S2. Convey materials into the feeding body 2; S3. Control the two extrusion components 31 to move towards each other, and extrude the material into the middle area of the feeding body 2; During the movement of the extrusion component 31, the linkage drives n sequentially rotating and connected actuators 321 to swing synchronously. The connection point between two adjacent actuators 321 moves back and forth along the height direction of the feeding body 2 to complete the material arch breaking operation.
[0058] The material is periodically squeezed by the relative displacement of two extrusion components 31, thereby achieving vibratory feeding while also breaking the static adhesion tendency of the material and inhibiting the formation of material bridging. When the two extrusion components 31 move relative to each other, the driving force is converted into the oscillating motion of n actuators 321 through the rotational connection point, which in turn causes the connection point of the two actuators 321 to reciprocate along the height direction of the feeding body 2, so as to form a vertical dispersing effect on the material, prevent material bridging, effectively solve the problem of material bridging during the feeding process, ensure the continuity of material feeding, improve the feeding efficiency, and thus reduce production costs.
