Description

Technical Field

[0001] This invention relates to the field of electric kilns, specifically a feeding device and an electric kiln thereof. Background Technology

[0002] A kiln is a furnace used to fire ceramic objects and sculptures or to fuse enamel onto the surface of metal objects. It is generally built of bricks and stones and can be made in various sizes as needed. It can be operated by combustible gas, oil or electricity. Electric kilns are easier to control the temperature than kilns that use combustible gas and oil, and the energy source is widely available and does not require transportation, and is precise and reliable.

[0003] Chinese utility model patent CN211668258U, published on October 13, 2020, discloses a convenient art ceramics processing kiln for loading and unloading. The kiln includes a furnace body, a support frame, and a feeding mechanism. The furnace body has a slidingly connected bottom plate, and the support frame is fixedly connected to the bottom of the furnace body. The right end of the support frame is fixedly connected to the feeding mechanism. The feeding mechanism includes a feeding frame, a servo motor, a feed screw, a sliding seat, electromagnets, and a control switch. The lower surface of the feeding frame has the feed screw and servo motor. Both ends of the feed screw are rotatably connected to the feeding frame. The servo motor is located below the feed screw and is rotatably connected to the feed screw via a chain. The upper surface of the feeding frame has a slidingly connected sliding seat, and symmetrically distributed electromagnets are fixedly connected to the surface of the sliding seat. This utility model, by providing a feeding mechanism at the edge of the furnace body, facilitates the quick and easy removal of finished art ceramics from the furnace while simultaneously allowing for the rapid loading of art ceramic blanks into the furnace, thus improving the kiln's production efficiency.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing feeding devices can only feed semi-finished products, but cannot feed fine particles, and cannot feed particles against gravity when the opening of the electric kiln is high and the feeding device is at a different height from the opening of the electric kiln. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems and provide a feeding device and its electric kiln.

[0006] To achieve the above objectives, the present invention employs the following technical solutions;

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A feeding device according to this invention includes a fixed frame and a lifting and conveying unit; the fixed frame is provided with the lifting and conveying unit; track plates are symmetrically fixed to the fixed frame; a second shaft is inserted into the track plates and the fixed frame; external clamping plates are symmetrically sleeved on the second shaft; a first sleeve plate is fixed between the external clamping plates; a second sleeve plate is slidably inserted into the first sleeve plate; a third sleeve plate is slidably inserted into the second sleeve plate; an elastic element is fixedly connected through an opening between the third sleeve plate and the first sleeve plate; a traction rope is fixedly connected to the third sleeve plate; a pull rod is fixedly connected to the end of the traction rope; the pull rod is inserted into a gripping tube; the gripping tube is fixed to the side of the external clamping plate; during operation, through... The lifting and conveying unit transports granular material from a low position to a high position, then aligns it with the opening of the electric kiln. One hand holds the lever, while the other hand holds the grip tube, moving it up and down to change the angle and extension length of the first, second, and third sets of plates. This allows the granular material to be directly conveyed deep into the electric kiln, achieving a roughly uniform distribution inside the kiln without the need for additional tools to adjust the material. This process of filling the kiln during loading is achieved, and the lifting and conveying unit allows the material to enter the kiln from low to high, eliminating the need to adjust the material to the same height within the kiln. This solves the problem of existing loading devices being unable to lift and load materials against gravity.

[0008] Furthermore, the lifting and conveying unit includes a first shaft, a first tube, and a first plate; the first shaft is symmetrically inserted into the fixed frame; the first tube is sleeved on the first shaft; the first plate is sleeved between the first shafts; a first clamping plate is fixedly connected to the first plate through an opening; a first motor is fixedly connected to the first clamping plate; a first belt is meshed and sleeved on the output shaft of the first motor; the other end of the first belt is meshed and driven by the first tube; a first grid belt is tensioned and sleeved on the first tube; during operation, the first motor is energized to drive the first belt and the first tube to rotate, thereby driving the first grid belt to rotate, so that the first grid belt horizontally conveys materials. The first grid belt is low off the ground, which facilitates the pouring of materials required by the electric kiln onto the first grid belt to complete the feeding action.

[0009] Furthermore, a second plate and a second tube are sleeved on the second shaft; a second grid belt is sleeved on the second tube; an elastic membrane is sealed and fixed between the second grid belts; a second clamping plate is slotted and fixed on the second plate; a second motor is fixed on the second clamping plate; a second belt is meshed and driven on the output shaft of the second motor; the other end of the second belt is meshed and connected to the second tube; during operation, the second motor drives the second belt and the second tube to rotate, thereby causing the second grid belt to rotate, thus conveying the material falling on the second grid belt upward to the opening of the electric kiln. With the help of other tools, the material can be conveyed into the electric kiln to complete the uniform feeding, or the material can be piled up near the opening of the electric kiln and then pushed into the electric kiln using tools. Through the second shaft, the second plate and the track plate, the angle of the second grid belt can be adjusted to adapt to electric kilns of different heights for feeding, thereby eliminating the need to adjust the height of the material to align with the electric kiln, reducing the difficulty of raising the material height, and solving the problem that existing material lifting and feeding devices cannot lift materials from a low position to a high position.

[0010] Furthermore, nuts are symmetrically threaded onto the second shaft corresponding to the track plate; a guide frame is fixedly connected to the inner surface of the fixing frame corresponding to the second grid belt; during operation, the nut is rotated to contact the track plate, thereby restricting the position of the second shaft within the track plate, thus fixing the tilt angle of the second grid belt, thereby adapting to electric kilns of different heights, allowing the upper end of the second grid belt to be aligned and inserted into the interior of the electric kiln, thus enabling continuous feeding of granular materials or materials of other shapes. The guide frame guides materials that fall during high-speed movement onto the second grid belt for feeding, preventing them from falling and solving the problem that existing horizontal feeding devices cannot achieve feeding materials of varying heights.

[0011] Furthermore, the external card plate has multiple rope holes corresponding to the traction rope; the lower surface of the fixed frame is fixed with multiple casters; during operation, the multiple casters fixed to the lower surface of the fixed frame allow the feeding device to easily move and align with the electric kiln, making feeding more accurate and faster, and also facilitating its movement away after feeding, thus making it easier to close and seal the electric kiln; the multiple rope holes on the external card plate corresponding to the traction rope restrict the movement path of the traction rope, preventing it from contacting other objects and causing interference or entanglement, thus ensuring the normal use of the traction function of the traction rope.

[0012] An electric kiln includes a feeding device as described above.

[0013] The feeding device and electric kiln provided by the present invention have the following beneficial effects:

[0014] 1. This invention uses a lifting conveyor unit to transport granular material from a low position to a high position, then aligns it with the opening of the electric kiln. One hand holds a lever and pulls the other hand holds a grip tube, moving it up and down to change the angle and extension length of the first, second, and third plates. This allows the granular material to be directly transported into the depths of the electric kiln and to roughly and evenly fill the interior of the kiln. This eliminates the need for additional tools to adjust the material, achieving full filling of the kiln interior during the feeding process. Furthermore, the lifting conveyor unit allows the material to enter the kiln from low to high, eliminating the need to adjust the material to the same height within the kiln. This solves the problem that existing feeding devices cannot perform gravity-assisted feeding.

[0015] 2. This invention uses a second motor to drive the second belt and the second pipe to rotate, thereby causing the second grid belt to rotate. This allows the material falling onto the second grid belt to move upwards and be conveyed to the opening of the electric kiln. With the help of other tools, the material can be conveyed into the electric kiln for uniform feeding, or the material can be piled up near the opening of the electric kiln and then pushed into the kiln using tools. The second shaft, in conjunction with the second plate and the track plate, allows the angle of the second grid belt to be adjusted to accommodate electric kilns of different heights. This eliminates the need to adjust the material height to align with the electric kiln, reducing the difficulty of raising the material height and solving the problem that existing material lifting and feeding devices cannot lift materials from a low position to a high position.

[0022] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that in the embodiments of the present invention, all directional indications (such as up-down-left-right-forward-backward...) are only used to explain the relative positional relationship and movement between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0025] Please see Figure 1-4As shown, a feeding device includes a fixed frame 1 and a lifting and conveying unit; the fixed frame 1 is provided with the lifting and conveying unit; track plates 29 are symmetrically fixed to the fixed frame 1; a second shaft 8 is inserted into the track plate 29 and the fixed frame 1; external clamping plates 17 are symmetrically sleeved on the second shaft 8; a first sleeve plate 18 is fixed between the external clamping plates 17; a second sleeve plate 19 is slidably inserted into the first sleeve plate 18; a third sleeve plate 20 is slidably inserted into the second sleeve plate 19; an elastic element 21 is fixedly connected through an opening between the third sleeve plate 20 and the first sleeve plate 18; a traction rope 22 is fixedly connected to the third sleeve plate 20; a pull rod 23 is fixedly connected to the end of the traction rope 22; the pull rod 23 is inserted into a grip tube 24; the grip tube 24 is fixed to the side of the external clamping plate 17. During operation, the lifting and conveying unit transports granular materials from a low position to a high position, aligns them with the opening of the electric kiln, and then, by holding the lever 23 with one hand and pulling the grip tube 24 with the other hand, the angles and extension lengths of the first set of plates 18, the second set of plates 19, and the third set of plates 20 are changed. This allows the granular materials to be directly transported into the depth of the electric kiln and to be roughly and evenly spread throughout the interior of the kiln. This eliminates the need for additional tools to adjust the materials, achieving full coverage of the interior of the electric kiln during the feeding process. Furthermore, the lifting and conveying unit allows the materials to enter the electric kiln from low to high, eliminating the need to adjust the materials to the same height within the kiln. This solves the problem that existing feeding devices cannot perform gravity-assisted feeding.

[0026] The lifting and conveying unit includes a first shaft 2, a first pipe 3, and a first plate 4; the first shaft 2 is symmetrically inserted into the fixed frame 1; the first pipe 3 is sleeved on the first shaft 2; the first plate 4 is sleeved between the first shafts 2; a first clamping plate 7 is fixedly connected to the first plate 4 with an opening; a first motor 6 is fixedly connected to the first clamping plate 7; a first belt 5 is meshed and sleeved on the output shaft of the first motor 6; the other end of the first belt 5 is meshed and driven to the first pipe 3; a first grid belt 13 is tensioned and sleeved on the first pipe 3; during operation, the first belt 5 and the first pipe 3 are rotated by the first motor 6, thereby driving the first grid belt 13 to rotate, so that the first grid belt 13 horizontally conveys materials. The first grid belt 13 is low off the ground, which makes it convenient to pour the materials required by the electric kiln onto the first grid belt 13 to complete the feeding action.

[0027] A second plate 16 and a second tube 9 are sleeved on the second shaft 8; a second grid belt 14 is sleeved on the second tube 9; an elastic membrane 15 is sealed and fixed between the second grid belts 14; a second clamping plate 12 is slotted and fixed on the second plate 16; a second motor 11 is fixed on the second clamping plate 12; a second belt 10 is meshed and driven on the output shaft of the second motor 11; the other end of the second belt 10 is meshed and connected to the second tube 9; during operation, the second motor 11 is energized to drive the second belt 10 and the second tube 9 to rotate, thereby causing the second grid belt 14 to rotate, thus discharging the contents onto the second grid belt 14. The material is conveyed upwards to the opening of the electric kiln. With the help of other tools, the material can be conveyed into the interior of the electric kiln to achieve uniform feeding. Alternatively, the material can be piled up near the opening of the electric kiln and then pushed into the interior of the electric kiln using tools. Through the second shaft 8, the second plate 16 and the track plate 29, the angle of the second grid belt 14 can be adjusted to adapt to electric kilns of different heights for feeding. This eliminates the need to adjust the height of the material to align with the electric kiln, reducing the difficulty of raising the material height and solving the problem that existing material lifting and feeding devices cannot lift materials from a low position to a high position.

[0028] Nuts 25 are symmetrically threaded onto the second shaft 8 corresponding to the track plate 29; a guide frame 27 is fixedly connected to the inner surface of the fixing frame 1 corresponding to the second grid belt 14; during operation, the nut 25 is rotated to contact the track plate 29, thereby restricting the position of the second shaft 8 within the track plate 29, thus fixing the tilt angle of the second grid belt 14, thereby adapting to electric kilns of different heights, allowing the upper end of the second grid belt 14 to be aligned and inserted into the interior of the electric kiln, thereby enabling continuous feeding of granular materials or materials of other shapes. The guide frame 27 guides materials that fall during high-speed movement to the second grid belt 14 for feeding, preventing them from falling and solving the problem that existing horizontal feeding devices cannot achieve feeding materials of different heights.

[0029] The external clamping plate 17 has multiple rope holes 26 corresponding to the traction rope 22; the lower surface of the fixed frame 1 is fixed with multiple casters 28; during operation, the multiple casters 28 fixed to the lower surface of the fixed frame 1 make it easy for the feeding device to move and align with the electric kiln, thereby making the feeding more accurate and faster, and also making it easy to move away after feeding, thus facilitating the closing and sealing of the electric kiln; the multiple rope holes 26 on the external clamping plate 17 corresponding to the traction rope 22 restrict the movement path of the traction rope 22, so that it will not come into contact with other objects and cause interference or entanglement, so that the traction function of the traction rope 22 can be used normally.

[0030] An electric kiln includes a feeding device as described above. During operation, the feeding device feeds material into the opening of the electric kiln, eliminating the need to pre-adjust the material height. This allows the material to be directly transported upwards into the electric kiln even when it is low off the ground, making it suitable for feeding electric kilns of different heights. This solves the problem that existing feeding devices can only feed material at the same horizontal height and cannot feed particulate matter.

[0031] Using the above solution, in use, the present invention uses a lifting conveyor unit to transport granular material from a low position to a high position, then aligns it with the opening of the electric kiln. One hand holds the pull rod 23 and the other hand holds the grip tube 24, moving it up and down to change the angle and extension length of the first set of plates 18, the second set of plates 19, and the third set of plates 20. This allows the granular material to be directly transported into the depths of the electric kiln and to be roughly and evenly distributed throughout the kiln's interior. Therefore, no additional tools are needed to adjust the material, achieving full distribution of the kiln's interior during the feeding process. Furthermore, the lifting conveyor unit allows the material to enter the kiln from a low to a high position, eliminating the need to adjust the material to the same height within the kiln. This solves the problems of existing feeding devices. To address the issue of materials not being able to be lifted and fed against gravity, the first motor 6 is energized to drive the first belt 5 and the first pipe 3 to rotate, thereby causing the first grid belt 13 to rotate. This allows the first grid belt 13 to horizontally transport materials. The low height of the first grid belt 13 from the ground facilitates the pouring of materials required for the electric kiln onto it. The second motor 11 is energized to drive the second belt 10 and the second pipe 9 to rotate, causing the second grid belt 14 to rotate. This lifts the materials falling onto the second grid belt 14 and transports them upwards to the opening of the electric kiln. With the help of other tools, the materials can be conveyed into the electric kiln for uniform feeding, or the materials can be piled up near the opening of the electric kiln and then pushed in using tools. Inside the electric kiln, the second shaft 8, in conjunction with the second plate 16 and the track plate 29, allows adjustment of the angle of the second grid belt 14. This adapts to electric kilns of different heights for feeding, eliminating the need to adjust the material height to align with the kiln. This reduces the difficulty of raising the material and solves the problem of existing material lifting and feeding devices being unable to lift materials from a low position to a high position. The rotating nut 25 contacts the track plate 29, restricting the position of the second shaft 8 within the track plate 29 and fixing the tilt angle of the second grid belt 14. This allows for adaptation to electric kilns of different heights, enabling the upper end of the second grid belt 14 to be aligned and inserted into the kiln, thus facilitating continuous feeding of granular materials or other shaped materials. The material, which falls during high-speed movement, is guided by the guide frame 27 to the second grid belt 14 for feeding, thus preventing it from falling and solving the problem that existing horizontal feeding devices cannot feed materials at different heights. Multiple casters 28 are fixed to the lower surface of the fixed frame 1, allowing the feeding device to easily move and align with the electric kiln, making feeding more precise and faster. It also facilitates movement away after feeding, making it easier to close and seal the electric kiln. Multiple rope holes 26 are provided on the external clamping plate 17 corresponding to the traction rope 22, restricting the movement path of the traction rope 22 and preventing it from contacting other objects and causing interference or entanglement, ensuring the normal operation of the traction function of the traction rope 22.By feeding material into the opening of the electric kiln through a feeding device, the material height can be moved upwards and conveyed into the kiln directly from a low height without needing to adjust it in advance. This allows for feeding of material into electric kilns of different heights, solving the problem that existing feeding devices can only feed at a single horizontal height and cannot feed particulate matter.
