Description

Technical Field

[0001] This application relates to the field of glass production equipment technology, and more specifically, to an automatic furnace feeder. Background Technology

[0002] Currently, in the glass production process, powders made from a mixture of various mineral raw materials need to be fed into the kiln by a feeder to be melted at high temperatures into molten glass. In large-scale kiln production, an automated storage system is usually used to store the powders, and various raw materials are mixed evenly in a certain proportion through a mixing station. Finally, the powders are continuously transported to the kiln through a special conveying equipment to ensure the continuity of production.

[0003] Traditional feeding methods are mostly manual, but this is inefficient, labor-intensive, and results in uneven feeding, affecting product quality. Existing automatic feeders also have shortcomings; for example, conveyor belt feeders are prone to deformation under high temperatures, and impurities from conveyor belt wear can enter the kiln, further impacting product quality. Traditional kiln feeders (such as large belt-type and bucket-type feeders) are bulky and require significant installation space, making them unsuitable for densely packed workshops with limited kiln spacing. The automatic glass kiln feeder disclosed in CN204058224U has a large storage hopper and moving device, requiring coordination with multiple silos for material transport, resulting in low space utilization and inconvenience for workshop layout. Some small feeding machines have low automation levels and require frequent manual intervention, which can easily lead to uneven distribution of raw materials in the kiln. For example, the small kiln automatic feeding machine with application number CN202411067637.2 includes a frame, feeding cylinder, feeding screw, etc., which can realize continuous feeding of powder in small experimental kilns at a low cost, but has certain limitations in terms of functional integration. Summary of the Invention

[0004] The purpose of this application is to provide an automatic kiln feeder that adopts an integrated and compact structure, a combination of vibratory feeding and reciprocating pushing, and a rotatable walking design, thereby solving the problems of uneven manual feeding, large size of automatic feeders, and poor adaptability in related technologies.

[0005] To achieve the above objectives, this application provides the following technical solution: An automatic kiln feeder includes: The frame is equipped with a feeding mechanism, a conveying mechanism, and a pushing mechanism; the conveying mechanism is used to feed material into the kiln inlet, and the feeding mechanism is used to supply material to the conveying mechanism. The pushing mechanism includes a pusher frame and a first reduction motor; the pusher frame is provided with a first connecting rod, a second connecting rod and a pusher arm; A connecting block is fixed to the output end of the first geared motor, and the connecting block is rotatably connected to the first connecting rod; The second connecting rod is hinged to the first end of the torsion arm, and the second end of the torsion arm is rotatably connected to the frame via the torsion arm shaft; The pusher arm is located at the end of the pusher frame away from the first connecting rod and extends to the kiln inlet. The end of the pusher arm away from the pusher frame is provided with a pusher for feeding materials. The frame is provided with a heat insulation plate on the side near the kiln. The heat insulation plate has a clearance opening for the pusher arm to extend and an opening for the discharge end of the feeding mechanism to pass through. It also includes a walking mechanism, which includes a base frame, wheels, a track and a limiting component. The wheels are located at the bottom of the base frame and roll in cooperation with the track. The limiting component is used to limit the position of the base frame relative to the track. The rotating mechanism includes a second geared motor, a rotating assembly, and a sensor switch. The frame is rotatably connected to the base frame via the rotating assembly, and the sensor switch is used to limit the rotation angle of the frame. The output end of the second geared motor is fixed with a gear, which meshes with an arc-shaped rack. The arc-shaped rack is fixed on the bottom frame, and the center of the arc-shaped rack coincides with the rotation center of the rotating assembly.

[0006] Furthermore, the feeding mechanism includes a feeding trough, an electromagnetic vibrator for driving the feeding trough to vibrate, and a spring bracket supporting the feeding trough. The spring brackets are in multiple sets and are symmetrically arranged below the feeding trough.

[0007] Furthermore, the rake frame is a rectangular frame structure, and the end of the rake frame near the first connecting rod is provided with a downward bending section. The first connecting rod is vertically fixed to the bending section, and the bending section extends toward the bottom of the frame.

[0008] Furthermore, there are two of each of the second connecting rods and torsion arms. The two second connecting rods are symmetrically arranged on both sides of the pusher frame, and the two torsion arms are respectively fixed to both ends of the torsion arm shaft. The torsion arm shaft is connected to the frame through a bearing seat.

[0009] Furthermore, the feeding mechanism includes a hopper and a discharge valve plate, the hopper being fixed to the upper part of the frame, and the discharge valve plate being located at the discharge port of the hopper.

[0010] Furthermore, the heat insulation board is an arc-shaped board.

[0011] Furthermore, the limiting component includes a limiting block fixed to the track and a stop block fixed to the outside of the bottom frame.

[0012] Furthermore, a protective plate is provided on the outside of the frame. The protective plate is a mesh plate and is detachably connected to the frame.

[0013] Compared with the prior art, this application has the following advantages: 1. Excellent material feeding uniformity: The pushing mechanism, driven by a drive unit, propels the rake frame. Combined with the hinged and rotating connection of the torsion arm, this achieves the reciprocating motion of the rake, evenly pushing material from the kiln inlet into the kiln. Simultaneously, the feeding mechanism uses an electromagnetic vibrator to drive the feeding trough, supported by multiple symmetrically arranged spring supports, ensuring uniform material distribution during transport from the feeding mechanism to the kiln inlet. This effectively solves the problem of uneven feeding during manual feeding. Furthermore, this pushing and feeding structure does not rely on a conveyor belt, avoiding the risk of conveyor belt deformation and wear under high temperatures, which could lead to impurities entering the kiln and further guarantee product quality.

[0014] 2. The overall equipment integrates the feeding mechanism, conveying mechanism, and pushing mechanism onto the frame, eliminating large redundant components. Compared to traditional large belt-type and bucket-type feeders, its size is significantly reduced, making it suitable for compact environments with dense workshop layouts and small kiln spacing. Simultaneously, the frame is connected to the traveling mechanism via a rotating mechanism. The wheels of the traveling mechanism work with the rails to move the equipment, facilitating positioning, installation, and maintenance without requiring significant space for fixed installation. The rotating mechanism, driven by a geared motor, engages a gear and an arc-shaped rack, causing the frame to rotate relative to the traveling mechanism, expanding the feeding coverage area and significantly improving space utilization.

[0015] 3. The heat insulation plates installed on the frame can prevent the high temperature of the kiln from affecting the internal components of the equipment, avoiding damage to the drive unit, connecting parts, etc., and extending the service life of key components. The equipment has a high degree of automation, reducing labor intensity. Compared with manual feeding and small feeding machines with low automation, the work efficiency is significantly improved. At the same time, the mobile design of the walking mechanism allows the equipment to be flexibly moved to different locations for use or maintenance, further improving the practicality and ease of maintenance of the equipment.

Detailed Implementation

[0018] To enable those skilled in the art to better understand this application, the technical solutions of this application will be clearly and completely described below in conjunction with embodiments. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0019] The following detailed explanation of specific implementation methods further illustrates this application: See Figures 1 to 7 This embodiment of an automatic kiln feeder includes a frame 1, on which a feeding mechanism, a conveying mechanism 3 and a pushing mechanism 4 are provided; it also includes a traveling mechanism 6, and the frame 1 is connected to the traveling mechanism 6 through a rotating mechanism 5.

[0020] Among them, see Figure 1The frame 1 is a three-dimensional frame structure welded from steel, with an overall rectangular shape. A horizontal base plate 12 is provided at the bottom to support the various functional mechanisms. A protective plate 11 is detachably connected to the outside of the frame 1 by bolts. The protective plate 11 is a mesh plate, which can prevent foreign objects from entering the equipment or operators from accidentally touching moving parts without affecting the observation of the equipment's operating status. The mesh structure also allows for better heat dissipation of the internal structural components.

[0021] Among them, see Figure 1 and Figure 6 The feeding mechanism includes a hopper 2 and a discharge valve plate (not shown in the figure). The hopper 2 has an inverted conical structure and is fixed to the upper part of the frame 1. The discharge port of the hopper 2 faces downward and is connected to the inlet end of the feeding trough 31 of the feeding mechanism 3. The discharge valve plate is located inside the discharge port of the hopper 2 and can control the amount of material falling by adjusting the opening. The hopper 2 can store a sufficient amount of material at one time, reducing the frequency of replenishment and improving production continuity. Preferably, an air hammer (not shown in the figure) can also be installed on the outer wall of the hopper 2. The vibration direction of the air hammer is towards the inside of the hopper 2, which can be used to prevent material from arching and blocking in the hopper 2 and ensure smooth material falling.

[0022] It should be noted that, for reference Figure 6 The discharge port of hopper 2 and the inlet of feeding trough 31 ( Figure 6 A certain gap is reserved between the hopper 2 and the feed trough 31, and no fixed connection structure such as welding or bolt fastening is used to avoid the constraint of the hopper 2 on the vibration of the feed trough 31. This ensures that the feed trough 31 can achieve stable vibration under the drive of the electromagnetic vibrator 32, so as to ensure the uniformity of material conveying. The air hammer and the discharge valve plate can both adopt existing technologies. The air hammer is a commercially available air hammer. When working, it directly impacts the outer wall of the hopper 2, using the impact force to break the adhesion and arching of materials on the inner wall of the hopper. This is suitable for the smooth feeding requirements of powder materials. The air hammer and the discharge valve plate can be assembled with the hopper 2 in a conventional installation manner to achieve the corresponding functions.

[0023] See Figure 6The feeding mechanism 3 includes a feeding trough 31, an electromagnetic vibrator 32, and spring supports 33. The feeding trough 31 has a U-shaped structure, with its inlet end connected to the outlet of the hopper 2 below, and its outlet end extending to the kiln inlet. The entire structure is horizontally positioned in the middle of the frame 1. The electromagnetic vibrator 32 is bolted to the bottom of the feeding trough 31, serving as the power source for the vibration of the feeding trough 31. It is connected to an external control system via wires, allowing for adjustment of the vibration frequency. Four sets of spring supports 33 are symmetrically arranged on both sides below the feeding trough 31. Each set of spring supports 33 includes an upper connecting plate, a lower connecting plate, and a damping spring. The upper connecting plate is fixedly connected to the feeding trough 31, and the lower connecting plate is bolted to the frame 1. The damping spring is fitted onto a guide post between the upper and lower connecting plates, providing elastic support for the feeding trough 31 and ensuring stability during vibration conveying.

[0024] It should be noted that, since the electromagnetic vibrator 32 is fixedly connected to the feeding trough 31, the reciprocating motion of the armature of the electromagnetic vibrator 32 is directly transmitted to the feeding trough 31, causing the feeding trough 31 to vibrate linearly at a set frequency. The material uses this motion as power to make continuous horizontal linear motion in the feeding trough 31, being thrown up and then moving forward a certain distance, falling down and then being thrown up again, thus completing the distribution and conveying of the material in a cyclical manner. By adjusting the frequency and amplitude of the current input to the electromagnetic coil through the external control system, the vibration frequency and amplitude of the feeding trough 31 can be controlled, thereby adapting to the conveying requirements of materials of different particle sizes, so that the material is evenly distributed in the feeding trough 31 and smoothly conveyed to the kiln inlet.

[0025] See Figure 5 The pushing mechanism 4 includes a pusher frame 41, a first geared motor 44 as a drive device, a torsion arm 42, a pusher 43, a first connecting rod 411, a second connecting rod 412, a connecting block 441, a torsion arm shaft 421, and a bearing seat 422. The pusher frame 41 has a rectangular frame structure, and in order to accommodate the low-position installation layout of the first geared motor 44 and avoid the installation space of the hopper 2, a downward bending section is provided at the end of the pusher frame 41 (the end near the first geared motor 44) to reduce the internal space occupied by the equipment. (See reference...) Figure 4 The rectangular frame of the pusher frame 41 is adapted to the lower part of the hopper 2, allowing the lower part of the hopper 2 to be contained within the frame, thus improving the compactness of the overall machine structure. (See reference...) Figure 5The first connecting rod 411 is vertically fixed at the middle of the bent section of the rake frame 41, and its axis is perpendicular to the central axis of the bent section of the rake frame 41. The first reduction motor 44 is fixedly mounted on the base plate 12 of the frame 1 through a motor mount and is located below the bent end of the rake frame 41. The connecting block 441 is a rectangular block, one end of which is fixedly connected to the output end of the first reduction motor 44, and the other end is rotatably connected to the end of the first connecting rod 411 away from the rake frame 41 through a rotating shaft, thereby realizing the driving connection between the first reduction motor 44 and the rake frame 41.

[0026] See Figure 5 Two second connecting rods 412 are provided, each vertically fixed to the rod portion on both sides of the rake frame 41, with their axes perpendicular to the axes of the rod portions on both sides of the rake frame 41. Two torsion arms 42 are provided, corresponding to the second connecting rods 412, symmetrically arranged on both sides of the rake frame 41; the upper end of each torsion arm 42 is hinged to the lower end of the corresponding second connecting rod 412. The two torsion arms 42 are fixedly connected to both ends of a torsion arm shaft 421, which is horizontally mounted on the frame 1 via two bearing seats 422. (See reference...) Figure 7 The bearing seat 422 is fixed to the pre-set vertical plate of the frame 1. The pusher 43 is a plate-shaped structure, preferably made of high-temperature resistant alloy steel, to ensure that it is not easily deformed or worn in the high-temperature environment of the kiln.

[0027] See Figure 5 Two pusher arms 431 are provided, and they have a bending structure to adapt to the installation space. One end of the two pusher arms 431 is symmetrically fixed to the opposite end of the pusher frame 41 away from the first connecting rod 411 (i.e. the end opposite to the bending section), and the bending direction is towards the kiln inlet. The other end of the two pusher arms 431 is fixedly connected to the back of the pusher 43.

[0028] See Figure 3 The heat insulation plate 7 is an arc-shaped plate. During production, the frame 1 reciprocates with the rotating mechanism 5. The arc-shaped plate can achieve maximum high-temperature barrier protection within the rotation range of the frame 1, reducing heat leakage. Furthermore, the arc-shaped structure can more comprehensively conform to the surrounding environment of the kiln inlet, reducing the equipment footprint while also increasing the heat insulation protection range. (See reference...) Figure 5 Two clearance openings 71 are provided on the heat insulation plate 7, located in the middle of the heat insulation plate 7, corresponding to the installation positions of the two pusher arms 431. The shape of the clearance openings 71 is adapted to the bending structure and movement trajectory of the pusher arms 431, and the opening size is slightly larger than the cross-sectional size of the pusher arms 431 to ensure that when the pusher arms 431 drive the pusher 43 in reciprocating motion, there will be no friction or interference with the heat insulation plate 7. Furthermore, see [reference needed]. Figure 7 An opening is provided at the lower middle part of the heat insulation plate 7 for the feeding trough 31 to extend out, and the discharge end of the feeding trough 31 extends through the opening to the kiln inlet.

[0029] Among them, see Figure 7 and Figure 8 The rotating mechanism 5 includes a second reduction motor 51, a gear 52, an arc-shaped rack 53, a rotating sleeve 54, and a sensor switch. The rotating sleeve 54 adopts a slewing bearing structure, with its upper end fixedly connected to the bottom of the base plate 12 of the frame 1 and its lower end fixedly connected to the top of the bottom frame 61 of the traveling mechanism 6, serving as a fulcrum for the rotation of the frame 1 relative to the traveling mechanism 6. The second reduction motor 51 is fixedly mounted on the base plate 12 of the frame 1, located on one side of the rotating sleeve 54. The gear 52 is fixed to the output end of the second reduction motor 51, and the arc-shaped rack 53 is fixed to the top of the bottom frame 61. The center of the arc-shaped rack 53 coincides with the rotation center of the rotating sleeve 54. The gear 52 meshes with the arc-shaped rack 53 to drive the rotation of the frame 1. The sensor switch (not shown in the figure) is fixed to one side of the rotating sleeve 54, with sensing points corresponding to both ends of the arc-shaped rack 53, used to limit the rotation angle of the frame 1, achieving positioning and limit protection.

[0030] It should be noted that the inductive switch is preferably an industrial sensor such as a proximity switch or photoelectric switch. The inductive switch sets sensing points at both ends of the arc-shaped rack 53. When the frame 1 rotates to the extreme position of one end of the arc-shaped rack 53, the inductive switch triggers a signal and transmits it to the external control system, which controls the second geared motor 51 to run in reverse. When the frame 1 rotates to the extreme position of the other end of the arc-shaped rack 53, the inductive switch triggers a signal again, which controls the second geared motor 51 to run in reverse again. This achieves the reciprocating rotation of the frame 1 within a preset range, which ensures that the material can be evenly covered in the feeding area and avoids excessive rotation that could cause damage to the parts due to collision, thus ensuring the safe and stable operation of the equipment.

[0031] In practice, the rotating mechanism 5 and the pushing mechanism 4 work in a coordinated manner. During normal operation, the rotating mechanism 5 drives the frame 1 and the pushing mechanism 4 mounted on it to continuously reciprocate within a preset range to expand the feeding coverage area. At the same time, the first reduction motor 44 of the pushing mechanism 4 continuously drives the pusher 43 to reciprocate, uniformly pushing the material delivered to different positions at the kiln inlet by the feeding trough 31 during the rotation into the kiln. This achieves both a wide distribution of material at the kiln inlet through rotation and ensures that material at each distribution position is pushed into the kiln through continuous pushing, effectively avoiding local material accumulation and further improving the uniformity of feeding, thus meeting the kiln's production requirements for continuous and uniform feeding.

[0032] See Figure 2To adapt to the dense workshop layout and small kiln spacing, and to simplify the arrangement and positioning of equipment within the workshop, this embodiment also includes a traveling mechanism 6. This allows the equipment to move and adjust its workstation flexibly, without requiring a large fixed area, thus improving workshop space utilization and layout flexibility. The traveling mechanism 6 includes a base frame 61, wheels 62, rails 63, and limiting components 64. The base frame 61 adopts a rectangular frame structure, with its overall dimensions adapted to the bottom of the frame 1, providing support for the upper structure. Multiple wheels 62 are respectively mounted on the bottom of the base frame 61 via axles and bearings, with grooves on the wheel surfaces adapted to the rails 63. The rails 63 are laid parallel to a predetermined position on the workshop floor and fixed to the ground with anchor bolts. The wheels 62 roll along the rails 63, enabling the equipment to move. (See reference...) Figure 3 and Figure 4 The limiting component 64 includes a limiting block disposed on one side of the track 63 and a stop block fixed to the outer side of the bottom frame 61. When the equipment moves to the preset limit position of the track 63, the stop block of the bottom frame 61 abuts against the limiting block of the track 63, and the positioning can be achieved by using bolt assemblies or other connecting parts through the through holes opened on the stop block and the limiting block, thereby realizing the quick locking of the entire equipment.

[0033] The working principle of this embodiment is as follows: The mobile device is positioned at the corresponding working position at the kiln inlet. The material to be added is added to the hopper 2, and the material falls from the outlet of the hopper 2 into the feeding trough 31 of the feeding mechanism 3. The electromagnetic vibrator 32 drives the feeding trough 31 to vibrate, and the material is continuously thrown up and moved forward under the action of vibration, and conveyed to the kiln inlet. While the feeding mechanism 3 continuously feeds, the pushing mechanism 4 and the rotating mechanism 5 work together. The first reduction motor 44 of the pushing mechanism 4 starts, driving the connecting block 441 to rotate. The connecting block 441 pulls the first connecting rod 411, causing the pusher frame 41 to swing back and forth, thereby driving the pusher 43 to move back and forth. At the same time, the rotating mechanism 5 drives the frame 1 to rotate back and forth within a preset angle. The pusher 43 pushes the material conveyed to different positions at the kiln inlet during the rotation process, pushing the material into the kiln. During the feeding process, the arc-shaped heat insulation plate 7 prevents the high temperature inside the kiln from spreading outward, protecting the key components inside the frame 1 from high temperature damage.
